Ecstasy

Ecstasy refers to a morbid mental condition, associated with an extreme sense of wellbeing, with a feeling of rapture, and temporary loss of self-control. It often presents as a form of religious obsession, with a feeling of direct communication with God, saintly voices and images being perceived. In milder cases the patient may preach as though with a divine mission to help others. Ecstasy may occur in happiness PSYCHOSIS, SCHIZOPHRENIA, certain forms of EPILEPSY, and abnormal personalities.

The term is also a street drug name for an amphetamine derivative, 3, 4-methylenedioxymethamphetamine or MDMA, increasingly used as a ‘recreational’ drug. It is classi?ed as a class A drug under the Misuse of Drugs Act 1971. MDMA is structurally similar to endogenous CATECHOLAMINES and produces central and peripheral sympathetic stimulation of alpha and beta ADRENERGIC RECEPTORS. It is taken into nerve terminals by the serotonin transporter and causes release of the NEUROTRANSMITTER substances serotonin and dopamine. Following this, SEROTONIN depletion is prolonged. As serotonin plays a major part in mood control, this leads to the characteristic ‘midweek depression’ experienced by MDMA users.

Several fatalities in young people have been attributed to adverse reactions resulting from MDMA use/abuse and possibly accompanying alcohol consumption. The principal effects are increase in pulse, blood pressure, temperature and respiratory rate. Additional complications such as cardiac ARRHYTHMIA, heatstroke-type syndrome, HYPONATRAEMIA and brain haemorrhage may occur. There is also concern over possible effects on the mental concentration and memory of those using ecstasy.

Management of patients who get to hospital is largely symptomatic and supportive but may include gastric decontamination, and use of DIAZEPAM as the ?rst line of treatment as it reduces central stimulation which may also reduce TACHYCARDIA, HYPERTENSION and PYREXIA.... ecstasy

Endometriosis

The presence of endometrial tissue outside of the uterus. The endometrium is the mucus membrane inner lining of the uterus, with glandular cells and structural cells, both responding to estrogen by increasing in size (the proliferative phase), the first responding to progesterone (the secretory phase); if there is endometrial tissue outside of the uterus, the tissue expands and shrinks in response to the estrus cycle, but the normal shedding of the menstrual phase can be difficult. The most common type of endometriosis is found in the fallopian tubes; the abnormal fallopian endometrial tissue can shed and drain into the uterus, but it hurts! It’s funny, but little tiny ducts, like the ureters, bile ducts, and fallopian tubes really cramp. The colon and uterus are big muscular tubes and, when cramped up, cause rather strong pain. When one of those little bitty things gets tenesmus, your face gets white (or light tan), you start to sweat, shiver, and revert to a fetal position. Endometriosis that occurs around the ovaries or inside the belly and therefore can NEVER drain is a purely physical and medical condition, but fallopian presence of endometrium usually reaches its peak in the early thirties. It can be helped by ensuring a strong estrogen and progesterone balance, thereby decreasing the tendency to form clots in the tubes, and to experience severe cramps every month... endometriosis

Enuresis

Involuntary voiding of urine... enuresis

Enzyme

Usually a protein made by the body to make chemical reactions take place at a faster rate or to cause a colour change in a laboratory test.... enzyme

Epidemic

A group of cases of a specific disease or illness clearly in excess of what one would normally expect in a particular geographic area. There is no absolute criterion for using the term epidemic; as standards and expectations change, so might the definition of an epidemic, e.g. an epidemic of violence.... epidemic

Epidemiology

The study of the various factors influencing the occurrence, distribution, prevention and control of disease, injury and other health-related events in a defined population. Epidemiology utilizes biology, clinical medicine, and statistics in an effort to understand the etiology (causes) and course of illness and/or disease. The ultimate goal of the epidemiologist is, not merely to identify underlying causes of a disease, but to apply findings to disease prevention and health promotion.... epidemiology

Elecampane

Inula helenium. N.O. Compositae.

Synonym: Aunee, Scabwort.

Habitat: Moist meadows and pasture land.

Features ? The stem. growing up to three feet, is branched, furrowed, and downy above; egg-shaped, serrate leaves embrace the stem. The calyx is also egg-shaped and leafy, and the flowers, blooming in July and August, are large, solitary and terminal, brilliantly yellow in colour. The root is light grey, hard, horny and cylindrical. The whole plant is similar in appearance to the horseradish, its taste is bitter and acrid, and the odour reminiscent of camphor.

Part used ? Root.

Action: Diaphoretic, expectorant and diuretic.

In combination with other remedies it is made up into cough medicines, and can be of service in pulmonary disorders generally. Skillfully compounded, slight alterative and tonic qualities are noticed. Wineglass doses are taken of a 1 ounce to 1 pint (reduced) decoction.

These modest present-day claims for Elecampane are far exceeded by Culpeper's exuberance. In his view, the root "warms a cold and windy stomach or the pricking therein, and stitches in the side caused by the spleen; helps the cough, shortness of the breath, and wheezing of the lungs. . . . Profitable for those that have their urine stopped. . . . Resisteth poison, and stayeth the venom of serpents, as also of putrid and pestilential fevers, and the plague itself." When we are also told by the same author that it kills and expels worms, fastens loose teeth, arrests dental decay, cleanses the skin from morphew, spots and blemishes, we realize in what esteem Elecampane was held in the seventeenth century! But here again germs of truth are hidden among manifold exaggerations.... elecampane

Encephalopathy

Any degenerative brain disease... encephalopathy

Endocarditis

In?ammation of the lining, valves and muscle of the HEART. The main causes are bacterial and virus infections and rheumatic fever, and the condition occurs most often in patients whose ENDOCARDIUM is already damaged by congenital deformities or whose immune system has been suppressed by drugs. Infection may be introduced into the bloodstream during dental treatment or surgical procedures, especially on the heart or on the gastrointestinal system. The condition is potentially very serious and treatment is with large doses of antibiotic drugs. (See HEART, DISEASES OF.)... endocarditis

Enema

Introduction of ?uid into the RECTUM via the

Percutaneous nephroscope used for examining the interior of the kidney. It is passed into the pelvis of the kidney through a track from the surface of the skin. (The track is made with a needle and guide wire.) Instruments can be passed through the nephroscope under direct vision to remove calculi.

ANUS. Enemas may be given to clear the intestine of faeces prior to intestinal surgery or to relieve severe constipation. They may also be used to give barium for diagnostic X-rays as well as drugs such as CORTICOSTEROIDS, used to treat ULCERATIVE COLITIS. The patient is placed on his or her side with a support under the hips. A catheter (see CATHETERS) with a lubricated end is inserted into the rectum and warmed enema ?uid gently injected. Disposable enemas and miniature enemas, which can be self-administered, are widely used; they contain preprepared solution.... enema

Enteric Fever

Typhoid and Paratyphoid. Septicaemic diseases caused by Salmonella typhi and Salmonella paratyphi.... enteric fever

Eosinophilia

A group of conditions having the characteristic elevation of eosinophils. These somewhat mysterious granulocytic leukocytes (white blood cells filled with cottage cheese) are definitely involved in parasite resistance, seem to initiate strong inflammation under some conditions, can facilitate clotting by inhibiting heparin, yet also are a part of the process of healing and inflammation control as an infection winds down. Eosinophilia is on one hand an inherited condition associated with atopic dermatitis (common, relatively benign, and irritating as hell), but, when acquired from chemical contact, drug reaction or spontaneously surfaced auto-immune response, it can destroy muscles, nerve, lungs, even kill. It caused the notorious string of chemical reactions that was triggered by tainted Japanese tryptophan.... eosinophilia

Erythema

Redness of the skin due to dilatation of dermal blood vessels. It may be transient or chronic, localised or widespread, and it can be blanched by pressure. Erythema may be caused by excessive exposure to heat or ultraviolet light, or by in?ammation of the skin due to infection, DERMATITIS, and various allergic reactions – for example, to drugs. It may be emotional (e.g. as in ?ushing), mediated by the autonomic nervous system.

Erythema ab igne is a ?xed redness of the skin caused by chronic exposure to heat from a domestic ?re or radiator.

Erythema pernio (See CHILBLAIN.) Redness induced by spasm of the skin arterioles due to cold. It affects the hands, feet or calves in winter. The red swollen areas are cooler than normal.

Erythema nodosum A singular pattern of red, tender nodules occurring on the shins, often lasting several weeks. It may be caused by a streptococcal throat infection, primary tuberculosis, SARCOIDOSIS, or may be drug-induced.

Erythema multiforme is an acute allergic eruption of the extremities characterised by circular areas of erythema, purpura and blistering, which resolve over two or three weeks, caused by infections or drugs. In severe forms the mucous membranes of the eyes, mouth and genitalia may be involved.

Erythema infectiosum is an acute contagious disease of children caused by a parvo-virus (see PARVOVIRUSES). In young children a bright erythema of the face gives a ‘slapped cheek’ appearance.

The use of ultrasonics (see ULTRASOUND) for the purpose of examining the HEART. By thus recording the echo (hence the name) from the heart of ultrasound waves, it is possible to study, for example, the movements of the heart valves as well as the state of the interior of the heart. Safe, reliable and painless, the procedure cuts the need for the physically interventionist procedure of CARDIAC CATHETERISATION.... echocardiography

See EYE, DISORDERS OF.... ectropion

Ectopic Pregnancy

An ectopic pregnancy most commonly develops in one of the FALLOPIAN TUBES. Occasionally it may occur in one of the OVARIES, and rarely in the uterine cervix or the abdominal cavity. Around one in 200 pregnant women have an ectopic gestation. As pregnancy proceeds, surrounding tissues may be damaged and, if serious bleeding happens, the woman may present as an ‘abdominal emergency’. A life-threatening condition, this needs urgent surgery. Most women recover satisfactorily and can have further pregnancies despite the removal of one Fallopian tube as a result of the ectopic gestation. Death is unusual. This disorder of pregnancy may occur because infection or a previous abdominal injury or operation may have damaged the normal descent of an ovum from the ovary to the womb. The ?rst symptoms usually appear during the ?rst two months of pregnancy, perhaps before the woman realises she is pregnant. Severe lower abdominal pain and vaginal bleeding are common presenting symptoms. Ultrasound can be used to diagnose the condition and laparoscopy can be used to remove the products of conception. (See PREGNANCY AND LABOUR.)... ectopic pregnancy

Edentulous

Lacking teeth: this may be because teeth have not developed or because they have been removed or fallen out.... edentulous

Effusion

The passage of ?uid through the walls of a blood vessel into a tissue or body cavity. It commonly occurs as a result of in?ammation or damage to the blood vessel. A pleural e?usion may occur in heart failure (as a result of increased blood pressure in the veins forcing out ?uid) or as a result of in?ammation in the lung tissue (PNEUMONIA). E?usions may also develop in damaged joints.... effusion

Ejaculation

The expulsion of SEMEN from the PENIS during ORGASM. The stimulation of sexual intercourse (coitus) or masturbation produces a spinal re?ex action that causes ejaculation. As well as containing spermatozoa (male germ cells), the semen comprises several constituents arising from COWPER’S GLANDS, the PROSTATE GLAND, the testicles and seminal vesicles (see TESTICLES) and these are discharged in sequence. (See also PREMATURE EJACULATION.)... ejaculation

Elder

Sambucus nigra. N.O. Caprifoliaceae.

Synonym: Black Elder. European Elder.

Habitat: Woods and hedges throughout Europe.

Features ? This familiar small tree, twelve to twenty feet high, has young branches containing light, spongy pith, with a bark that is light grey and corky externally. The leaves are opposite, deep green and smooth. Creamy-white, flat-topped masses of flowers bloom in July, to be followed by the decorative, drooping bunches of purplish-black, juicy berries. Country folk aptly limit our English summer when they say that it does not arrive until the Elder is in full blossom, and ends when the berries are ripe!

Part used ? Flowers.

Action: Diaphoretic, emollient, alterative, diuretic.

These properties of the flowers are obtained from infusions of 1 ounce to

1 pint of water in wineglass doses. It is used, often in conjunction with Peppermint and Yarrow, chiefly for the reduction of feverish colds, but inflamed conditions of the eyes are also found to yield to bathing with the warm Elder flower infusion. Although the medicinal qualities are weaker in the berries than in the flowers, the popular Elder berry wine is widely used as part of the treatment for colds and influenza.

An ointment made from the leaves has been of help to sufferers from chilblains.... elder

Electrocautery

The use of an electrically heated needle or loop to destroy diseased or unwanted tissue. Benign growths, warts and polyps can be removed with this technique.... electrocautery

Electrocoagulation

A method of sealing blood vessels using heat generated by high-frequency electric current through ?ne needles or a surgical knife. The procedure is used during surgery to close newly cut vessels. It can also be used to stop nosebleeds and to remove vascular deformities such as naevi (see NAEVUS).... electrocoagulation

Electrophoresis

The migration of charged particles between electrodes. A simple method of electrophoresis, known as paper electrophoresis, has been introduced to analyse PROTEIN in body ?uids. This method consists in applying the protein-containing solution as a spot or a streak to a strip of ?lter paper which has been soaked in bu?er solution and across the ends of which a potential di?erence is then applied for some hours. Comparison is made between ?lter strips of normal ?uids and that of the patient under investigation. Identi?cation and quanti?cation of proteins in the blood are possible using this method.... electrophoresis

Embolectomy

Surgical removal of a clot or EMBOLUS to clear an obstruction in an artery (see ARTERIES, DISEASES OF). The obstruction may be cleared by inserting a balloon (Fogarty) catheter (see CATHETERS) into the blood vessel or by surgical incision through the arterial wall. Embolectomy may be a life-saving operation when a patient has a PULMONARY EMBOLISM.... embolectomy

Endometrium

The mucous membrane which lines the interior of the UTERUS.... endometrium

Endorphins

Peptides (see PEPTIDE) produced in the brain which have a pain-relieving action; hence their alternative name of opiate peptides. Their name is derived from endogenous MORPHINE. They have been de?ned as endogenous opiates or any naturally occurring substances in the brain with pharmacological actions resembling opiate alkaloids such as morphine. There is some evidence that the pain-relieving action of ACUPUNCTURE may be due to the release of these opiate peptides. It has also been suggested that they may have an antipsychotic action and therefore be of value in the treatment of major psychotic illnesses such as SCHIZOPHRENIA.... endorphins

Endoscope

A tube-shaped instrument inserted into a cavity in the body to investigate and treat disorders. It is ?exible and equipped with lenses and a light source. Examples of endoscopes are the CYSTOSCOPE for use in the bladder, the GASTROSCOPE for examining the stomach and the ARTHROSCOPE for looking into joints (see also FIBREOPTIC ENDOSCOPY).... endoscope

Endothelium

The membrane lining various vessels and cavities of the body, such as the pleura (lining the lung), the pericardium (lining the heart), the peritoneum (lining the abdomen and abdominal organs), the lymphatic vessels, blood vessels, and joints. It consists of a ?brous layer covered with thin ?at cells, which render the surface perfectly smooth and secrete the ?uid for its lubrication.... endothelium

Enterobiasis

Infection with Enterobius vermicularis, the threadworm (or pinworm as it is known in the USA). It is the most common of all the intestinal parasites in Britain, and the least harmful. The male is about 6 mm (••• inch) in length and the female about 12 mm (••• inch) in length. Each resembles a little piece of thread. These worms live in considerable numbers in the lower bowel, affecting children particularly. They usually cause no symptoms but can result in great irritation round the anus or within the female genitalia, especially at night when the female worm emerges from the anus to lay its eggs and then die. The most e?ective form of treatment is either viprynium embonate or piperazine citrate, which needs to be taken by the whole family. Bedclothes must then be laundered.... enterobiasis

Entropion

See EYE, DISORDERS OF.... entropion

Eosinophil

Any cell in the body with granules in its substance that stain easily with the dye, eosin. Granulocytes which form about 2 per cent of the white cells of the blood are eosinophils.... eosinophil

Ephedrine

An alkaloid (see ALKALOIDS) derived from a species of Ephedra or prepared synthetically. A BRONCHODILATOR, it was once widely used to treat asthma, but has now been superseded by the much safer (and more e?ective) selective beta-2-adrenoceptor stimulants (see ADRENERGIC RECEPTORS). Ephedrine is a constituent of several decongestant cold and cough remedies available to the general public.... ephedrine

Genus of dermatophyte fungi associated with tinea or ringworm in humans.... epidermophyton

Epididymis

An oblong body attached to the upper part of each TESTICLE, composed of convoluted vessels and ducts, that connects the VASA EFFERENTIA to the VAS DEFERENS. Sperm cells produced in the testis pass along the epididymis, maturing as they go, to be stored in the seminal vesicles until EJACULATION occurs. The epididymis may be damaged by trauma or infection resulting sometimes in sterility. Cysts may also occur.... epididymis

Epidural Anaesthesia

See ANAESTHESIA.... epidural anaesthesia

Epiglottis

A leaf-like piece of elastic CARTILAGE covered with mucous membrane, which stands upright between the back of the tongue and the glottis, or entrance to the LARYNX. In the act of swallowing, it prevents ?uids and solids from passing o? the back of the tongue into the larynx.... epiglottis

Epiglottitis

Acute epiglottitis is a septicaemic illness which includes an acute in?ammatory OEDEMA of the EPIGLOTTIS, due to Haemophilus in?uenzae. It progresses very rapidly and a child can be dangerously ill or even die within hours of onset. Once recognised, however, it is easily and successfully treated by immediate transfer to hospital for emergency intubation and ventilation and use of antibiotics and steroids. Fortunately it is now very rare as a result of the introduction of haemophilus vaccine into the primary vaccination course of infants. (See LARYNGOTRACHEO-BRONCHITIS.)... epiglottitis

Epiloia

Epithelioma

Epithelioma is a tumour of malignant nature arising in the EPITHELIUM covering the surface of the body. (See CANCER.)... epithelioma

Epithelium

Epithelium is the cellular layer which forms the epidermis on the skin, covers the inner surface of the bowels, and forms the lining of ducts and hollow organs, like the bladder. It consists of one or more layers of cells which adhere to one another, and is one of the simplest tissues of the body. It is of several forms: for example, the epidermis is formed of scaly epithelium, the cells being in several layers and more or less ?attened. (See SKIN.) The bowels are lined by a single layer of columnar epithelium, the cells being long and narrow in shape. The air passages are lined by ciliated epithelium: that is to say, each cell is provided with ?agellae (lashes) which drive the ?uid upon the surface of the passages gradually upwards.... epithelium

Epstein Barr Virus

The virus that causes glandular fever or infectious MONONUCLEOSIS. It is similar to the viruses that cause herpes and is associated with BURKITT’S LYMPHOMA. It has been suggested as precipitating some attacks of MYALGIC ENCEPHALOMYELITIS (ME), also known as CHRONIC FATIGUE SYNDROME (CFS).... epstein barr virus

Erection

The rigid state of the PENIS when it responds to sexual stimulus. An erection is necessary for e?ective penetration of the VAGINA. As a result of sexual arousal, the three cylinders of erectile tissue in the penis become engorged with blood, lengthening, raising and hardening the penis. Muscles surrounding the blood vessels contract and retain the blood in the penis. Erections also occur during sleep and in young boys. Inability to have or maintain an erection is one cause of IMPOTENCE (see also SILDENAFIL CITRATE).... erection

An active constituent of ergot, it has a powerful action in controlling the excessive bleeding from the UTERUS which may occur after childbirth. The o?cial British Pharmacopoeia preparation is ergometrine maleate.... ergometrine

Ergotamine

One of the alkaloids in ergot. In the form of ergotamine tartrate it is usually given orally to treat MIGRAINE, but treatment carries a risk and should be medically supervised.... ergotamine

Eruption

Eruption, or rash, means an outbreak, in a scattered form, upon the surface of the skin. The skin is usually raised and red, or it may be covered with scales, or crusts, or vesicles containing ?uid. Eruptions di?er in appearance: for example, the eruption of MEASLES is always distinguishable from that of CHICKENPOX. But the same disease may also produce di?erent eruptions in di?erent people; or in the same person in di?erent states of health; or even on di?erent parts of the body at one time.

Eruptions may be acute or chronic. Most of the acute eruptions belong to the exanthemata (see EXANTHEM): that is, they are bright in col-our and burst out suddenly like a ?ower. These are the eruptions of SCARLET FEVER, measles, German measles (see RUBELLA), SMALLPOX and chickenpox. In general, the severity of these diseases can be measured by the amount of eruption. Some eruptions are very transitory, like nettle-rash, appearing and vanishing again in the course of a few hours. (See also SKIN, DISEASES OF.)... eruption

Erythrasma

A super?cial mild infection of the skin caused by CORYNEBACTERIA. It produces pink or slightly brown ?aky areas of skin usually on the upper inner thighs or axillae. Toe clefts may be affected with thickened, white, macerated skin. The affected areas ?uoresce coral pink under ultraviolet light. CLOTRIMAZOLE or KETOCONAZOLE cream clears the rash rapidly. Very extensive erythrasma responds to oral ERYTHROMYCIN given for seven days.... erythrasma

Erythromycin

One of the MACROLIDES, it has an antibacterial spectrum similar, but not identical, to that of penicillin. The drug is a valuable alternative for patients who are allergic to penicillin. Erythromycin is used for respiratory infections, including spread within a family of WHOOPINGCOUGH, and also CHLAMYDIA, LEGIONNAIRE’S DISEASE, SYPHILIS and enteritis caused by CAMPYLOBACTER. It is also used with neomycin when preparing for bowel surgery. Though often active against penicillin-resistant staphylococci, these bacteria are now sometimes resistant to erythromycin. The drug may be given orally, intravenously or topically (for acne).... erythromycin

Eschar

Hard adherent crust caused by tissue killed by heat, chemicals or disease.... eschar

Erythroderma

A rare in?ammation of the skin which causes universal itching. The skin is red, thickened and scaly. It is also called generalised exfoliative dermatitis (see SKIN, DISEASES OF). It may complicate chronic eczema (see DERMATITIS) or PSORIASIS, particularly in men, in the second half of life. It may also result from HYPERSENSITIVITY to a drug, such as gold injections used in RHEUMATOID ARTHRITIS. Rarely, it may be a manifestation of T-cell LYMPHOMA.

Universal in?ammation of the skin may cause heart failure, particularly in elderly people with pre-existing heart disease. It may lead to HYPOTHERMIA due to excessive heat loss from the skin and protein de?ciency caused by the shedding of large quantities of skin scales containing keratin. Rarely, these complications can be fatal.

Treatment depends on the cause, but in eczematous erythroderma, oral CORTICOSTEROIDS (PREDNISOLONE) in full dosage may be needed.... erythroderma

Ethambutol

Ethambutol is a synthetic drug, often included in the treatment regimen of TUBERCULOSIS when the infection is thought to be resistant to other drugs. The main side-effects are visual disturbances, chie?y loss of acuity and colour blindness. Such toxic effects are more common when excessive dosages are used, or the patient has some renal impairment, in which case the drug should be avoided – as it should be in young children.... ethambutol

Ethanol

Ethanol is another name for ethyl alcohol. (See ALCOHOL.)... ethanol

Ether

A colourless, volatile, highly in?ammable liquid, formed by the action of sulphuric acid on alcohol. Ether boils below body temperature and therefore rapidly evaporates when sprayed over the skin. Dissolving many substances such as fats, oils and resins better than alcohol or water, it is used in the preparation of many drugs. Formerly used as an anaesthetic, it has been replaced by safer and more e?cient drugs.... ether

Ethinylestradiol

A highly active oestrogen – about 20 times more active than STILBOESTROL; it is active when given by mouth. (See OESTROGENS.)... ethinylestradiol

Ethosuximide

A drug used in the treatment of the form of EPILEPSY known as petit mal.... ethosuximide

Euphoria

A feeling of well-being. This may occur normally; for instance, when someone has passed an examination. In some neurological or psychiatric conditions, however, patients may have an exaggerated and quite unjusti?ed feeling of euphoria. This is then a symptom of the underlying condition.

Evidence-based Medicine

The process of systematically identifying, appraising and using the best available research ?ndings, integrated with clinical expertise, as the basis for clinical decisions about individual patients. The aim is to encourage clinicians, health-service managers and consumers of health care to make decisions, taking account of the best available evidence, on the likely consequences of alternative decisions and actions. Evidence-based medicine has been developing internationally for the past 25 years, but since around 1990 its development has accelerated. The International COCHRANE COLLABORATION ?nds and reviews relevant research. Several other centres have been set up to look at the clinical application of research results, including the Centre for Evidence-Based Medicine in Oxford.... evidence-based medicine

Exchange Transfusion

A method of treating newborn infants with HAEMOLYTIC DISEASE. Blood is taken out of the baby through the umbilical vein and is replaced with the same quantity of blood from a donor that is compatible with the mother’s blood. The procedure is repeated several times to get rid of damaged cells while maintaining the infant’s blood volume and keeping its red cell count constant. (See also TRANSFUSION.)... exchange transfusion

Excimer Laser

A type of laser that is used to remove thin sheets of tissue from the surface of the cornea (see EYE), thus changing the curvature of the eye’s corneal surface.

Exercise

An activity requiring physical exertion. Everyone should take regular exercise: this keeps muscles in tone, maintains the CARDIOVASCULAR SYSTEM in good shape, helps to keep weight at an optimum level and promotes relaxation and sleep. When an individual is at rest, the heart’s output is 5 litres of blood per minute. When running at 12 km (7••• miles) per hour, this rises to around 25 litres, obliging the heart and lungs to operate more e?ciently and speeding up the metabolism of food to provide the necessary energy. Lack of exercise by children may lead to faulty posture and ?abby muscles; in adults it results in an increase in weight and poorly functioning respiratory and cardiovascular system, with an increased chance of heart disease later in life. Adolescents and adults, participating regularly in sporting activities, should train regularly, preferably under expert supervision, to ensure that they do not place potentially damaging demands on their cardiovascular, respiratory and musculoskeletal systems. Those wanting to participate in demanding sports would be wise to have a medical examination before embarking on training programmes (see SPORTS MEDICINE).... exercise

Exomphalos

The term applied to a congenital HERNIA formed by the projection of abdominal organs through the UMBILICUS.... exomphalos

Exophthalmos

Exophthalmos, or PROPTOSIS, refers to forward displacement of the eyeball and must be distinguished from retraction of the eyelids, which causes an illusion of exophthalmos. Lid retraction usually results from activation of the autonomic nervous sytem. Exophthalmos is a more serious disorder caused by in?ammatory and in?ltrative changes in the retro-orbital tissues and is essentially a feature of Graves’ disease, though it has been described in chronic thyroiditis (see THYROID GLAND, DISEASES OF). Exophthalmos commonly starts shortly after the development of thyrotoxicosis but may occur months or even years after hyperthyroidism has been successfully treated. The degree of exophthalmos is not correlated with the severity of hyperthyroidism even when their onset is simultaneous. Some of the worst examples of endocrine exophthalmos occur in the euthyroid state and may appear in patients who have never had thyrotoxicosis; this disorder is named ophthalmic Graves’ disease. The exophthalmos of Graves’ disease is due to autoimmunity (see IMMUNITY). Antibodies to surface antigens on the eye muscles are produced and this causes an in?ammatory reaction in the muscle and retroorbital tissues.

Exophthalmos may also occur as a result of OEDEMA, injury, cavernous venous THROMBOSIS or a tumour at the back of the eye, pushing the eyeball forwards. In this situation it is always unilateral.... exophthalmos

Expectorants

Drugs which are claimed to help the removal of secretions from the AIR PASSAGES – although there is no convincing evidence that they do this. A simple expectorant may, however, be a useful placebo. Most preparations are available without a doctor’s prescription and pharmacists will advise on which might be helpful for particular patients with dry or congestive coughs.... expectorants

Extrapyramidal System

This is a complex part of the nervous system, extending from the cortex to the medulla in the BRAIN, from which emerge descending spinal pathways which in?uence voluntary motor activity throughout the body. Although the normal functions of the system are poorly understood, there are characteristic signs of an extrapyramidal LESION. These include disturbance of voluntary movements, notably slowness and ‘poverty’ of movement; disturbance of muscular tone, which may be increased or decreased; and involuntary movements, such as a tremor, irregular jerking movements, or slow writhing movements.

Diseases There are several diseases that result from lesions to the extrapyramidal system, of which the most common is PARKINSONISM. Others include WILSON’S DISEASE, KERNICTERUS, CHOREA and ATHETOSIS.... extrapyramidal system

Eyebright

Euphrasia. officinalis. N.O. Scrophulariaceae.

Synonym: Birdeye, Brighteye.

Habitat: Plentiful on commons, heaths, and in meadows, as well as on sea cliffs, but varies considerably in growth and development with the richness of the soil.

Features ? The stems are four to six inches long, and under suitable soil conditions, branched below. The lower leaves are opposite each other, and alternate higher up the stem, small, dark green, lanceolate or nearly rhomboid above, deeply cut, proceeding directly from the stem. The flowers are small, axillary, and range in hue between white and purple, while some are delicately variegated with yellow. The taste is bitter, salty and slightly astringent.

Action: Astringent and tonic.

This herb, as its name indicates, is valued mainly as an application in

inflammation and weakness of the eyes, and is frequently combined with Golden Seal to make an excellent lotion for this purpose. A large pinch of the herb should be infused with sufficient boiling water for each application. The eyebath should be freshly filled for each eye, care being taken to strain thoroughly before using the tepid lotion.

Euphrasia is also employed externally to arrest hemorrhages.... eyebright

Genetic Engineering

Genetic engineering, or recombinant DNA technology, has only developed in the past decade or so; it is the process of changing the genetic material of a cell (see CELLS). GENES from one cell – for example, a human cell – can be inserted into another cell, usually a bacterium, and made to function. It is now possible to insert the gene responsible for the production of human INSULIN, human GROWTH HORMONE and INTERFERON from a human cell into a bacterium. Segments of DNA for insertion can be prepared by breaking long chains into smaller pieces by the use of restriction enzymes. The segments are then inserted into the affecting organism by using PLASMIDS and bacteriophages (see BACTERIOPHAGE). Plasmids are small packets of DNA that are found within bacteria and can be passed from one bacterium to another.

Already genetic engineering is contributing to easing the problems of diagnosis. DNA analysis and production of MONOCLONAL ANTIBODIES are other applications of genetic engineering. Genetic engineering has signi?cantly contributed to horticulture and agriculture with certain characteristics of one organism or variant of a species being transfected (a method of gene transfer) into another. This has given rise to higher-yield crops and to alteration in colouring and size in produce. Genetic engineering is also contributing to our knowledge of how human genes function, as these can be transfected into mice and other animals which can then act as models for genetic therapy. Studying the effects of inherited mutations derived from human DNA in these animal models is thus a very important and much faster way of learning about human disease.

Genetic engineering is a scienti?c procedure that could have profound implications for the human race. Manipulating heredity would be an unwelcome activity under the control of maverick scientists, politicians or others in positions of power.... genetic engineering

Urgent medical attention is required to control the condition, or the patient may suffer permanent brain damage.... status epilepticus

Pre-eclampsia

A complication of pregnancy (see PREGNANCY AND LABOUR), of unknown cause, which in severe cases may proceed to ECLAMPSIA. It is characterised by HYPERTENSION, renal impairment, OEDEMA, often with PROTEINURIA and disseminated intravascular coagulation. It usually occurs in the second half of pregnancy – mild cases (without proteinuria) occurring in about 10 per cent of pregnancies, severe cases in about 2 per cent. Predisposing factors include a ?rst pregnancy, or pregnancy by a new partner; a family history of pre-eclampsia, hypertension, or other cardiovascular disorders; and preexisting hypertension or DIABETES MELLITUS. Increased incidence with lower socio-economic class may be linked to diet or to failure to attend for antenatal care. Although less common in smokers, fetal outlook is worse. Multiple pregnancy and HYDATIDIFORM MOLE, together with hydrops fetalis (see HAEMOLYTIC DISEASE OF THE NEWBORN), predispose to early and severe pre-eclampsia.

Treatment Severe pre-eclampsia is an emergency, and urgent admission to hospital should be arranged. Treatment should be given to control the hypertension; the fetal heart rate carefully monitored; and in very severe cases urgent CAESAREAN SECTION may be necessary.... pre-eclampsia

Pulmonary Embolism

The condition in which an embolus (see EMBOLISM), or clot, is lodged in the LUNGS. The source of the clot is usually the veins of the lower abdomen or legs, in which clot formation has occurred as a result of the occurrence of DEEP VEIN THROMBOSIS (DVT) – THROMBOPHLEBITIS (see VEINS, DISEASES OF). Thrombophlebitis, with or without pulmonary embolism, is a not uncommon complication of surgical operations, especially in older patients. This is one reason why nowadays such patients are got up out of bed as quickly as possible, or, alternatively, are encouraged to move and exercise their legs regularly in bed. Long periods of sitting, particularly when travelling, can cause DVT with the risk of pulmonary embolism. The severity of a pulmonary embolism, which is characterised by the sudden onset of pain in the chest, with or without the coughing up of blood, and a varying degree of SHOCK, depends upon the size of the clot. If large enough, it may prove immediately fatal; in other cases, immediate operation may be needed to remove the clot; whilst in less severe cases anticoagulant treatment, in the form of HEPARIN, is given to prevent extension of the clot. For some operations, such as hip-joint replacements, with a high risk of deep-vein thrombosis in the leg, heparin is given for several days postoperatively.... pulmonary embolism

Importance: Eclipta is one of the ten auspicious herbs that constitute the group dasapuspam which is considered to destroy the causative factors of all unhealthy and unpleasant features and bestow good health and prosperity. The members of this group cure wounds and ulcers as well as fever caused by the derangement of the tridosas - vata, pitta and kapha. It is used in hepatitis, spleen enlargements, chronic skin diseases, tetanus and elephantiasis. The leaf promotes hair growth and use as an antidote in scorpion sting. The root is used as an emetic, in scalding of urine, conjuctivitis and as an antiseptic to ulcers and wound in cattle. It is used to prevent abortion and miscarriage and also in cases of uterine pains after the delivery. The juice of the plant with honey is given to infants for expulsion of worms. For the relief in piles, fumigation with Eclipta is considered beneficial. A decoction of the leaves is used in uterine haemorrhage. The paste prepared by mincing fresh plants has got an antiinflammatory effect and may be applied on insect bites, stings, swellings and other skin diseases. In Ayurveda, it is mainly used in hair oil, while in Unani system, the juice is used in “Hab Miskeen Nawaz” along with aconite, triphala, Croton tiglium, Piper nigium, Piper longum, Zingiber officinale and minerals like mercury, sulphur, arsenic, borax, etc. for various types of pains in the body. It is also a constituent of “Roghan Amla Khas” for applying on the hair and of “Majun Murrawah-ul-arwah”.

Distribution: This plant is widely distributed in the warm humid tropics with plenty of rainfall. It grows commonly in moist places as a weed all over plains of India.

Botany: Eclipta prostrata (Linn) Linn. syn. E. alba Hassk. is an annual, erect or postrate herb, often rooting at nodes. Leaves are sessile, 2.5-7.5cm long with white appressed hairs. Floral heads are 6-8 mm in diameter, solitary and white. Fruit is an achene, compressed and narrowly winged. Sometimes, Wedelia calendulacea, which resembles Eclipta prostrata is used for the same purpose.

Properties and activity: The leaves contain stigmasterol, -terthienylmethanol, wedelolactone, dismethylwedelolactone and dismethylwedelolactone-7-glucoside. The roots give hentriacontanol and heptacosanol. The roots contain polyacetylene substituted thiophenes. The aerial part is reported to contain a phytosterol, -amyrin in the n-hexane extract and luteolin-7-glucoside, -glucoside of phytosterol, a glucoside of a triterpenic acid and wedelolactone in polar solvent extract. The polypeptides isolated from the plant yield cystine, glutamic acid, phenyl alanine, tyrosine and methionine on hydrolysis. Nicotine and nicotinic acid are reported to occur in this plant.

The plant is anticatarrhal, febrifuge, antidontalgic, absorbent, antihepatic, CVS active, nematicidal, ovicidal and spasmolytic in activity. The alcoholic extract of entire plant has been reported to have antiviral activity against Ranikhet disease virus. Aqueous extract of the plant showed subjective improvement of vision in the case of refractive errors.

Eggs

Nutritional Profile Energy value (calories per serving): Moderate Protein: High Fat: High Saturated fat: Moderate Cholesterol: High Carbohydrates: Low Fiber: None Sodium: Moderate to high Major vitamin contribution: Vitamin A, riboflavin, vitamin D Major mineral contribution: Iron, calcium

About the Nutrients in This Food An egg is really three separate foods, the whole egg, the white, and the yolk, each with its own distinct nutritional profile. A whole egg is a high-fat, high-cholesterol, high-quality protein food packaged in a high-calcium shell that can be ground and added to any recipe. The proteins in eggs, with sufficient amounts of all the essential amino acids, are 99 percent digestible, the standard by which all other proteins are judged. The egg white is a high-protein, low-fat food with virtually no cholesterol. Its only important vitamin is riboflavin (vitamin B2), a vis- ible vitamin that gives egg white a slightly greenish cast. Raw egg whites contain avidin, an antinutrient that binds biotin a B complex vitamin for- merly known as vitamin H, into an insoluble compound. Cooking the egg inactivates avidin. An egg yolk is a high-fat, high-cholesterol, high-protein food, a good source of vitamin A derived from carotenes eaten by the laying hen, plus vitamin D, B vitamins, and heme iron, the form of iron most easily absorbed by your body. One large whole egg (50 g/1.8 ounce) has five grams fat (1.5 g satu- rated fat, 1.9 g monounsaturated fat, 0.7 g polyunsaturated fat), 212 mg cholesterol, 244 IU vitamin A (11 percent of the R DA for a woman, 9 percent * Values are for a whole egg. of the R DA for a man), 0.9 mg iron (5 percent of the R DA for a woman, 11 percent of the R DA for a man) and seven grams protein. The fat in the egg is all in the yolk. The protein is divided: four grams in the white, three grams in the yolk.

The Most Nutritious Way to Serve This Food With extra whites and fewer yolks to lower the fat and cholesterol per serving.

Diets That May Restrict or Exclude This Food Controlled-fat, low-cholesterol diet Low-protein diet

Buying This Food Look for: Eggs stored in the refrigerated dair y case. Check the date for freshness. NOTE : In 1998, the FDA and USDA Food Safety and Inspection Service (FSIS) proposed new rules that would require distributors to keep eggs refrigerated on the way to the store and require stores to keep eggs in a refrigerated case. The egg package must have a “refrigera- tion required” label plus safe-handling instructions on eggs that have not been treated to kill Salmonella. Look for: Eggs that fit your needs. Eggs are graded by the size of the yolk and the thick- ness of the white, qualities that affect appearance but not nutritional values. The higher the grade, the thicker the yolk and the thicker the white will be when you cook the egg. A Grade A A egg fried sunny side up will look much more attractive than a Grade B egg prepared the same way, but both will be equally nutritions. Egg sizes ( Jumbo, Extra large, Large, Medium, Small) are determined by how much the eggs weigh per dozen. The color of the egg’s shell depends on the breed of the hen that laid the egg and has nothing to do with the egg’s food value.

Storing This Food Store fresh eggs with the small end down so that the yolk is completely submerged in the egg white (which contains antibacterial properties, nature’s protection for the yolk—or a developing chick embryo in a fertilized egg). Never wash eggs before storing them: The water will make the egg shell more porous, allowing harmful microorganisms to enter. Store separated leftover yolks and whites in small, tightly covered containers in the refrigerator, where they may stay fresh for up to a week. Raw eggs are very susceptible to Salmonella and other bacterial contamination; discard any egg that looks or smells the least bit unusual. Refrigerate hard-cooked eggs, including decorated Easter eggs. They, too, are suscep- tible to Salmonella contamination and should never be left at room temperature.

Preparing This Food First, find out how fresh the eggs really are. The freshest ones are the eggs that sink and lie flat on their sides when submerged in cool water. These eggs can be used for any dish. By the time the egg is a week old, the air pocket inside, near the broad end, has expanded so that the broad end tilts up as the egg is submerged in cool water. The yolk and the white inside have begun to separate; these eggs are easier to peel when hard-cooked. A week or two later, the egg’s air pocket has expanded enough to cause the broad end of the egg to point straight up when you put the egg in water. By now the egg is runny and should be used in sauces where it doesn’t matter if it isn’t picture-perfect. After four weeks, the egg will float. Throw it away. Eggs are easily contaminated with Salmonella microorganisms that can slip through an intact shell. never eat or serve a dish or bever age containing r aw fr esh eggs. sa lmonella is destroyed by cooking eggs to an inter nal temper atur e of 145°f ; egg-milk dishes such as custar ds must be cooked to an inter nal temper atur e of 160°f. If you separate fresh eggs by hand, wash your hands thoroughly before touching other food, dishes, or cooking tools. When you have finished preparing raw eggs, wash your hands and all utensils thoroughly with soap and hot water. never stir cooked eggs with a utensil used on r aw eggs. When you whip an egg white, you change the structure of its protein molecules which unfold, breaking bonds between atoms on the same molecule and forming new bonds to atoms on adjacent molecules. The result is a network of protein molecules that hardens around air trapped in bubbles in the net. If you beat the whites too long, the foam will turn stiff enough to hold its shape even if you don’t cook it, but it will be too stiff to expand natu- rally if you heat it, as in a soufflé. When you do cook properly whipped egg white foam, the hot air inside the bubbles will expand. Ovalbumin, an elastic protein in the white, allows the bubble walls to bulge outward until they are cooked firm and the network is stabilized as a puff y soufflé. The bowl in which you whip the whites should be absolutely free of fat or grease, since the fat molecules will surround the protein molecules in the egg white and keep them from linking up together to form a puff y white foam. Eggs whites will react with metal ions from the surface of an aluminum bowl to form dark particles that discolor the egg-white foam. You can whip eggs successfully in an enamel or glass bowl, but they will do best in a copper bowl because copper ions bind to the egg and stabilize the foam.

What Happens When You Cook This Food When you heat a whole egg, its protein molecules behave exactly as they do when you whip an egg white. They unfold, form new bonds, and create a protein network, this time with molecules of water caught in the net. As the egg cooks, the protein network tightens, squeez- ing out moisture, and the egg becomes opaque. The longer you cook the egg, the tighter the network will be. If you cook the egg too long, the protein network will contract strongly enough to force out all the moisture. That is why overcooked egg custards run and why overcooked eggs are rubbery. If you mix eggs with milk or water before you cook them, the molecules of liquid will surround and separate the egg’s protein molecules so that it takes more energy (higher heat) to make the protein molecules coagulate. Scrambled eggs made with milk are softer than plain scrambled eggs cooked at the same temperature. When you boil an egg in its shell, the air inside expands and begins to escape through the shell as tiny bubbles. Sometimes, however, the force of the air is enough to crack the shell. Since there’s no way for you to tell in advance whether any particular egg is strong enough to resist the pressure of the bubbling air, the best solution is to create a safety vent by sticking a pin through the broad end of the egg before you start to boil it. Or you can slow the rate at which the air inside the shell expands by starting the egg in cold water and letting it warm up naturally as the water warms rather than plunging it cold into boiling water—which makes the air expand so quickly that the shell is virtually certain to crack. As the egg heats, a little bit of the protein in its white will decompose, releasing sulfur that links up with hydrogen in the egg, forming hydrogen sulfide, the gas that gives rot- ten eggs their distinctive smell. The hydrogen sulfide collects near the coolest part of the egg—the yolk. The yolk contains iron, which now displaces the hydrogen in the hydrogen sulfide to form a green iron-sulfide ring around the hard-cooked yolk.

How Other Kinds of Processing Affect This Food Egg substitutes. Fat-free, cholesterol-free egg substitutes are made of pasteurized egg whites, plus artificial or natural colors, flavors, and texturizers (food gums) to make the product look and taste like eggs, plus vitamins and minerals to produce the nutritional equivalent of a full egg. Pasteurized egg substitutes may be used without additional cooking, that is, in salad dressings and eggnog. Drying. Dried eggs have virtually the same nutritive value as fresh eggs. Always refrigerate dried eggs in an air- and moistureproof container. At room temperature, they will lose about a third of their vitamin A in six months.

Medical Uses and/or Benefits Protein source. The protein in eggs, like protein from all animal foods, is complete. That is, protein from animal foods provides all the essential amino acids required by human beings. In fact, the protein from eggs is so well absorbed and utilized by the human body that it is considered the standard by which all other dietary protein is measured. On a scale known as biological value, eggs rank 100 ; milk, 93; beef and fish, 75; and poultry, 72. Vision protection. The egg yolk is a rich source of the yellow-orange carotenoid pigments lutein and zeaxanthin. Both appear to play a role in protecting the eyes from damaging ultraviolet light, thus reducing the risk of cataracts and age-related macular degeneration, a leading cause of vision of loss in one-third of all Americans older than 75. Just 1.3 egg yolks a day appear to increase blood levels of lutein and zeaxanthin by up to 128 percent. Perhaps as a result, data released by the National Eye Institute’s 6,000-person Beaver Dam ( Wisconsin) Eye Study in 2003 indicated that egg consumption was inversely associated with cataract risk in study participants who were younger than 65 years of age when the study started. The relative risk of cataracts was 0.4 for people in the highest category of egg consumption, compared to a risk of 1.0 for those in the lowest category. External cosmetic effects. Beaten egg whites can be used as a facial mask to make your skin look smoother temporarily. The mask works because the egg proteins constrict as they dry on your face, pulling at the dried layer of cells on top of your skin. When you wash off the egg white, you also wash off some of these loose cells. Used in a rinse or shampoo, the pro- tein in a beaten raw egg can make your hair look smoother and shinier temporarily by filling in chinks and notches on the hair shaft.

Adverse Effects Associated with This Food Increased risk of cardiovascular disease. Although egg yolks are high in cholesterol, data from several recent studies suggest that eating eggs may not increase the risk of heart disease. In 2003, a report from a 14-year, 177,000-plus person study at the Harvard School of Public Health showed that people who eat one egg a day have exactly the same risk of heart disease as those who eat one egg or fewer per week. A similar report from the Multiple R isk Factor Intervention Trial showed an inverse relationship between egg consumption and cholesterol levels—that is, people who ate more eggs had lower cholesterol levels. Nonetheless, in 2006 the National Heart, Lung, and Blood Institute still recommends no more than four egg yolks a week (including the yolk in baked goods) for a heart-healthy diet. The American Heart Association says consumers can have one whole egg a day if they limit cholesterol from other sources to the amount suggested by the National Cholesterol Education Project following the Step I and Step II diets. (Both groups permit an unlimited number of egg whites.) The Step I diet provides no more than 30 percent of total daily calories from fat, no more than 10 percent of total daily calories from saturated fat, and no more than 300 mg of cholesterol per day. It is designed for healthy people whose cholesterol is in the range of 200 –239 mg/dL. The Step II diet provides 25– 35 percent of total calories from fat, less than 7 percent of total calories from saturated fat, up to 10 percent of total calories from polyunsaturated fat, up to 20 percent of total calories from monounsaturated fat, and less than 300 mg cho- lesterol per day. This stricter regimen is designed for people who have one or more of the following conditions: •  Existing cardiovascular disease •  High levels of low-density lipoproteins (LDLs, or “bad” cholesterol) or low levels of high-density lipoproteins (HDLs, or “good” cholesterol) •  Obesity •  Type 1 diabetes (insulin-dependent diabetes, or diabetes mellitus) •  Metabolic syndrome, a.k.a. insulin resistance syndrome, a cluster of risk fac- tors that includes type 2 diabetes (non-insulin-dependent diabetes) Food poisoning. Raw eggs (see above) and egg-rich foods such as custards and cream pies are excellent media for microorganisms, including the ones that cause food poisoning. To protect yourself against egg-related poisoning, always cook eggs thoroughly: poach them five minutes over boiling water or boil at least seven minutes or fry two to three minutes on each side (no runny center) or scramble until firm. Bread with egg coating, such as French toast, should be cooked crisp. Custards should be firm and, once cooked, served very hot or refrigerated and served very cold. Allergic reaction. According to the Merck Manual, eggs are one of the 12 foods most likely to trigger the classic food allergy symptoms: hives, swelling of the lips and eyes, and upset stomach. The others are berries (blackberries, blueberries, raspberries, strawberries), choco- late, corn, fish, legumes (green peas, lima beans, peanuts, soybeans), milk, nuts, peaches, pork, shellfish, and wheat (see wheat cer ea ls).

Food/Drug Interactions Sensitivity to vaccines. Live-virus measles vaccine, live-virus mumps vaccine, and the vac- cines for influenza are grown in either chick embryo or egg culture. They may all contain minute residual amounts of egg proteins that may provoke a hypersensitivity reaction in people with a history of anaphylactic reactions to eggs (hives, swelling of the mouth and throat, difficulty breathing, a drop in blood pressure, or shock).... eggs

Embryo Transfer

Embryo transfer is the process whereby the initial stages of procreation are produced outside the human body and completed in the uterus or womb. The procedure is also known as ‘embryo transplantation’ and ‘in vitro fertilisation’ (IVF). It consists of extracting an ovum (or egg) from the prospective mother’s body and placing this in a dish where it is mixed with the male partner’s SEMEN and special nutrient ?uids. After the ovum is fertilised by the sperm it is transferred to another dish containing a special nutrient solution. Here it is left for several days while the normal early stages of development (see FETUS) take place. The early EMBRYO, as it has then become, is then implanted in the mother’s uterus, where it ‘takes root’ and develops as a normal fetus.

The ?rst ‘test-tube baby’ – to use the popular, and widely used, term for such a child – was born by CAESAREAN SECTION in England on 25 July 1978. Many other children conceived in this manner have since been born, and, though only 10 per cent of women conceive at the ?rst attempt, the overall success rate is improving. Embryo transplantation and research are controversial procedures and in many countries, including the UK, are controlled by legislation. Embryo transfer and research using embryos are regulated by the Human Fertilisation & Embryology Authority (see ASSISTED CONCEPTION; APPENDIX 7: STATUTORY ORGANISATIONS).... embryo transfer

Emotion

Mental arousal that the individual may ?nd enjoyable or unpleasant. The three components are subjective, physiological and behavioural. The instinctive fear and ?ee response in animals comprises physiological reaction – raised heart rate, pallor and sweating – to an unpleasant event or stimulus. The loving relationship between mother and child is another wellrecognised emotional event. If this emotional bond is absent or inadequate, the child may suffer emotional deprivation, which can be the trigger for behavioural problems ranging from attention-craving to aggression. Emotional problems are common in human society, covering a wide spectrum of psychological disturbances. Upbringing, relationships or psychiatric illnesses such as anxiety and DEPRESSION may all contribute to the development of emotional problems (see MENTAL ILLNESS).... emotion

In?ammation of the endocardium is called ENDOCARDITIS.... endocardium

Endocrine Glands

Organs whose function it is to secrete into the blood or lymph, substances known as HORMONES. These play an important part in general changes to or the activities of other organs at a distance. Various diseases arise as the result of defects or excess in the internal secretions of the di?erent glands. The chief endocrine glands are:

Adrenal glands These two glands, also known as suprarenal glands, lie immediately above the kidneys. The central or medullary portion of the glands forms the secretions known as ADRENALINE (or epinephrine) and NORADRENALINE. Adrenaline acts upon structures innervated by sympathetic nerves. Brie?y, the blood vessels of the skin and of the abdominal viscera (except the intestines) are constricted, and at the same time the arteries of the muscles and the coronary arteries are dilated; systolic blood pressure rises; blood sugar increases; the metabolic rate rises; muscle fatigue is diminished. The super?cial or cortical part of the glands produces steroid-based substances such as aldosterone, cortisone, hydrocortisone, and deoxycortone acetate, for the maintenance of life. It is the absence of these substances, due to atrophy or destruction of the suprarenal cortex, that is responsible for the condition known as ADDISON’S DISEASE. (See CORTICOSTEROIDS.)

Ovaries and testicles The ovary (see OVARIES) secretes at least two hormones – known, respectively, as oestradiol (follicular hormone) and progesterone (corpus luteum hormone). Oestradiol develops (under the stimulus of the anterior pituitary lobe – see PITUITARY GLAND below, and under separate entry) each time an ovum in the ovary becomes mature, and causes extensive proliferation of the ENDOMETRIUM lining the UTERUS, a stage ending with shedding of the ovum about 14 days before the onset of MENSTRUATION. The corpus luteum, which then forms, secretes both progesterone and oestradiol. Progesterone brings about great activity of the glands in the endometrium. The uterus is now ready to receive the ovum if it is fertilised. If fertilisation does not occur, the corpus luteum degenerates, the hormones cease acting, and menstruation takes place.

The hormone secreted by the testicles (see TESTICLE) is known as TESTOSTERONE. It is responsible for the growth of the male secondary sex characteristics.

Pancreas This gland is situated in the upper part of the abdomen and, in addition to the digestive enzymes, it produces INSULIN within specialised cells (islets of Langerhans). This controls carbohydrate metabolism; faulty or absent insulin production causes DIABETES MELLITUS.

Parathyroid glands These are four minute glands lying at the side of, or behind, the thyroid (see below). They have a certain e?ect in controlling the absorption of calcium salts by the bones and other tissues. When their secretion is defective, TETANY occurs.

Pituitary gland This gland is attached to the base of the brain and rests in a hollow on the base of the skull. It is the most important of all endocrine glands and consists of two embryologically and functionally distinct lobes.

The function of the anterior lobe depends on the secretion by the HYPOTHALAMUS of certain ‘neuro-hormones’ which control the secretion of the pituitary trophic hormones. The hypothalamic centres involved in the control of speci?c pituitary hormones appear to be anatomically separate. Through the pituitary trophic hormones the activity of the thyroid, adrenal cortex and the sex glands is controlled. The anterior pituitary and the target glands are linked through a feedback control cycle. The liberation of trophic hormones is inhibited by a rising concentration of the circulating hormone of the target gland, and stimulated by a fall in its concentration. Six trophic (polypeptide) hormones are formed by the anterior pituitary. Growth hormone (GH) and prolactin are simple proteins formed in the acidophil cells. Follicle-stimulating hormone (FSH), luteinising hormone (LH) and thyroid-stimulating hormone (TSH) are glycoproteins formed in the basophil cells. Adrenocorticotrophic hormone (ACTH), although a polypeptide, is derived from basophil cells.

The posterior pituitary lobe, or neurohypophysis, is closely connected with the hypothalamus by the hypothalamic-hypophyseal tracts. It is concerned with the production or storage of OXYTOCIN and vasopressin (the antidiuretic hormone).

PITUITARY HORMONES Growth hormone, gonadotrophic hormone, adrenocorticotrophic hormone and thyrotrophic hormones can be assayed in blood or urine by radio-immunoassay techniques. Growth hormone extracted from human pituitary glands obtained at autopsy was available for clinical use until 1985, when it was withdrawn as it is believed to carry the virus responsible for CREUTZFELDT-JAKOB DISEASE (COD). However, growth hormone produced by DNA recombinant techniques is now available as somatropin. Synthetic growth hormone is used to treat de?ciency of the natural hormone in children and adults, TURNER’S SYNDROME and chronic renal insu?ciency in children.

Human pituitary gonadotrophins are readily obtained from post-menopausal urine. Commercial extracts from this source are available and are e?ective for treatment of infertility due to gonadotrophin insu?ciency.

The adrenocorticotrophic hormone is extracted from animal pituitary glands and has been available therapeutically for many years. It is used as a test of adrenal function, and, under certain circumstances, in conditions for which corticosteroid therapy is indicated (see CORTICOSTEROIDS). The pharmacologically active polypeptide of ACTH has been synthesised and is called tetracosactrin. Thyrotrophic hormone is also available but it has no therapeutic application.

HYPOTHALAMIC RELEASING HORMONES which affect the release of each of the six anterior pituitary hormones have been identi?ed. Their blood levels are only one-thousandth of those of the pituitary trophic hormones. The release of thyrotrophin, adrenocorticotrophin, growth hormone, follicle-stimulating hormone and luteinising hormone is stimulated, while release of prolactin is inhibited. The structure of the releasing hormones for TSH, FSH-LH, GH and, most recently, ACTH is known and they have all been synthesised. Thyrotrophin-releasing hormone (TRH) is used as a diagnostic test of thyroid function but it has no therapeutic application. FSH-LH-releasing hormone provides a useful diagnostic test of gonadotrophin reserve in patients with pituitary disease, and is now used in the treatment of infertility and AMENORRHOEA in patients with functional hypothalamic disturbance. As this is the most common variety of secondary amenorrhoea, the potential use is great. Most cases of congenital de?ciency of GH, FSH, LH and ACTH are due to defects in the hypothalamic production of releasing hormone and are not a primary pituitary defect, so that the therapeutic implication of this synthesised group of releasing hormones is considerable.

GALACTORRHOEA is frequently due to a microadenoma (see ADENOMA) of the pituitary. DOPAMINE is the prolactin-release inhibiting hormone. Its duration of action is short so its therapeutic value is limited. However, BROMOCRIPTINE is a dopamine agonist with a more prolonged action and is e?ective treatment for galactorrhoea.

Thyroid gland The functions of the thyroid gland are controlled by the pituitary gland (see above) and the hypothalamus, situated in the brain. The thyroid, situated in the front of the neck below the LARYNX, helps to regulate the body’s METABOLISM. It comprises two lobes each side of the TRACHEA joined by an isthmus. Two types of secretory cells in the gland – follicular cells (the majority) and parafollicular cells – secrete, respectively, the iodine-containing hormones THYROXINE (T4) and TRI-IODOTHYRONINE (T3), and the hormone CALCITONIN. T3 and T4 help control metabolism and calcitonin, in conjunction with parathyroid hormone (see above), regulates the body’s calcium balance. De?ciencies in thyroid function produce HYPOTHYROIDISM and, in children, retarded development. Excess thyroid activity causes thyrotoxicosis. (See THYROID GLAND, DISEASES OF.)... endocrine glands

Endoscopy

Examination of a body cavity – for example, PLEURAL CAVITY, GASTROINTESTINAL TRACT, BILE DUCT and URINARY BLADDER – using an ENDOSCOPE in order to diagnose or treat a disorder in the cavity. The development of endoscopy has reduced the need for major surgery, as many diagnostic procedures can be performed with an endoscope (as can MINIMALLY INVASIVE SURGERY (MIS)). The development of ?bre optics (the transmission of light along bundles of glass or plastic ?bres) has greatly advanced the practice of endoscopy and hospitals now routinely run endoscopy clinics on an out-patient basis, often without the necessity for a general anaesthetic.... endoscopy

Enteral Feeding

In severely ill patients, the metabolic responses to tissue damage may be su?cient to cause a reduction of muscle mass and of plasma proteins. This state of CATABOLISM may also impair the immune response to infection and delay the healing of wounds. It is probable that as many as one-half of patients who have had a major operation a week previously show evidence of protein malnutrition. This can be detected clinically by a loss of weight and a reduction in the skinfold thickness and arm circumference. Biochemically the serum-albumin (see ALBUMINS) concentration falls, as does the LYMPHOCYTE count. The protein reserves of the body fall even more dramatically when there are SEPSIS, burns, acute pancreatitis or renal failure.

The purpose of enteral feeding is to give a liquid, low-residue food through a naso-gastric feeding tube. It has the advantage over parenteral nutrition that the septic complications of insertion of CATHETERS into veins are avoided. Enteral feeding may either take the form of intermittent feeding through a large-bore naso-gastric tube, or of continuous gravity-feeding through a ?ne-bore tube.

A number of proprietary enteral foods are available. Some contain whole protein as the nitrogen source; others – and these are called elemental diets – contain free amino acids. DIARRHOEA is the most common problem with enteral feeding and it tends to occur when enteral feeding is introduced too rapidly or with too strong a preparation.... enteral feeding

Erosion means a process of gradual wearing down of structures in the body. The term is applied to the e?ect of tumours, when they cause destruction of tissue in their neighbourhood without actually growing into the latter: for example, an ANEURYSM may erode bones in its neighbourhood. The term is also applied to minute ulcers – for example, erosions of the stomach, caused by extreme acidity of the gastric juice.

Dental erosion is the loss of tooth substance due to a cause other than decay or trauma. This is usually as a result of the presence of acid; for example, frequent vomiting or the excessive intake of citrus fruits. The teeth appear very smooth and later develop saucer-shaped depressions.... erosion

Eryngo

Eryngium maritimum. N.O. Umbelliferae.

Synonym: Commonly known as Sea Holly and Sea Eryngo.

Habitat: The plant is seen only on the sand dunes of the sea shore.

Features ? A pale greenish-blue bloom is characteristic of the erect, smooth stem, which grows to nearly one foot. Stiff, wavy, roundish leaves are roughly divided into three short, broad lobes, with beautiful veins and sharp teeth at the margins. Root leaves have stalks, but those from the stem are sessile. Blooming from July to September, the bright, pale blue flowers form a dense, round head at the end of

branches. The blackish-brown roots, long, thin arid cylindrical, are topped with the bristly remnants of the leaf stalks, and have a sweetish, mucilaginous taste.

Part used ? The root is the only part of the plant recognised in herbalism.

Action: Eryngo root is a diaphoretic, diuretic and expectorant.

It is mostly prescribed for bladder disorders, such as difficult and painful micturation, and also forms part of the treatment for uterine irritation.

Richard Lawrence Hool, of the British and American Physio-Medical Association, advises it in "sluggishness of the liver with uric acid accumulations," prepared as follows:

"Sea Holly 1 ounce

Wild Carrot 1 ounce.

"Boil in 1 1/2 pints of water down to 1 pint; strain, and take a wineglassful four times a day. In cases of jaundice take:

"Sea Holly 1 ounce

Barberry bark 1/2 ounce

"Boil in 1 quart of new milk for 10 minutes. Strain, and take two wineglassfuls every three hours." He adds ? "Most obstinate cases have been known to yield to this remedy in from 7-to 14 days."... eryngo

E. coli is also used in laboratory experiments for genetic and bacteriological research.... escherichia

Erythromelalgia

A condition in which the ?ngers or toes, or even larger portions of the limbs, become purple and bloated in appearance, and very painful. In people suffering from the condition – which is not a common one – the attacks come and go, being worse in summer (unlike chilblains), and worse on exertion or when the affected parts are warmed or allowed to hang down. The condition may appear without apparent cause, but is often associated with vascular diseases, such as HYPERTENSION and POLYCYTHAEMIA VERA. It aso occurs in association with certain diseases of the central nervous system, and in cases of metallic poisoning

(e.g. arsenic, mercury and thallium). Treatment is unsatisfactory but aspirin provides sympomatic relief.... erythromelalgia

Ethics

Within most cultures, care of the sick is seen as entailing special duties, codi?ed as a set of moral standards governing professional practice. Although these duties have been stated and interpreted in di?ering ways, a common factor is the awareness of an imbalance of power between doctor and patient and an acknowledgement of the vulnerability of the sick person. A function of medical ethics is to counteract this inevitable power imbalance by encouraging doctors to act in the best interests of their patients, refrain from taking advantage of those in their care, and use their skills in a manner which preserves the honour of their profession. It has always been accepted, however, that doctors cannot use their knowledge indiscriminately to ful?l patients’ wishes. The deliberate ending of life, for example, even at a patient’s request, has usually been seen as alien to the shared values inherent in medical ethics. It is, however, symptomatic of changing concepts of ethics and of the growing power of patient choice that legal challenges have been mounted in several countries to the prohibition of EUTHANASIA. Thus ethics can be seen as regulating individual doctor-patient relationships, integrating doctors within a moral community of their professional peers and re?ecting societal demands for change.

Medical ethics are embedded in cultural values which evolve. Acceptance of abortion within well-de?ned legal parameters in some jurisdictions is an example of how society in?uences the way in which perceptions about ethical obligations change. Because they are often linked to the moral views predominating in society, medical ethics cannot be seen as embodying uniform standards independent of cultural context. Some countries which permit capital punishment or female genital mutilation (FGM – see CIRCUMCISION), for example, expect doctors to carry out such procedures. Some doctors would argue that their ethical obligation to minimise pain and suffering obliges them to comply, whereas others would deem their ethical obligations to be the complete opposite. The medical community attempts to address such variations by establish-ing globally applicable ethical principles through debate within bodies such as the World Medical Association (WMA) or World Psychiatric Association (WPA). Norm-setting bodies increasingly re?ect accepted concepts of human rights and patient rights within professional ethical codes.

Practical changes within society may affect the perceived balance of power within the doctor-patient relationship, and therefore have an impact on ethics. In developed societies, for example, patients are increasingly well informed about treatment options: media such as the Internet provide them with access to specialised knowledge. Social measures such as a well-established complaints system, procedures for legal redress, and guarantees of rights such as those set out in the NHS’s Patient’s Charter appear to reduce the perceived imbalance in the relationship. Law as well as ethics emphasises the importance of informed patient consent and the often legally binding nature of informed patient refusal of treatment. Ethics re?ect the changing relationship by emphasising skills such as e?ective communication and generation of mutual trust within a doctor-patient partnership.

A widely known modern code is the WMA’s International Code of Medical Ethics which seeks to provide a modern restatement of the Hippocratic principles.

Traditionally, ethical codes have sought to establish absolutist positions. The WMA code, for example, imposes an apparently absolute duty of con?dentiality which extends beyond the patient’s death. Increasingly, however, ethics are perceived as a tool for making morally appropriate decisions in a sphere where there is rarely one ‘right’ answer. Many factors – such as current emphasis on autonomy and the individual values of patients; awareness of social and cultural diversity; and the phenomenal advance of new technology which has blurred some moral distinctions about what constitutes a ‘person’ – have contributed to the perception that ethical dilemmas have to be resolved on a case-by-case basis.

An approach adopted by American ethicists has been moral analysis of cases using four fundamental principles: autonomy, bene?cence, non-male?cence and justice. The ‘four principles’ provide a useful framework within which ethical dilemmas can be teased out, but they are criticised for their apparent simplicity in the face of complex problems and for the fact that the moral imperatives implicit in each principle often con?ict with some or all of the other three. As with any other approach to problem-solving, the ‘four principles’ require interpretation. Enduring ethical precepts such as the obligation to bene?t patients and avoid harm (bene?cence and non-male?cence) may be differently interpreted in cases where prolongation of life is contrary to a patient’s wishes or where sentience has been irrevocably lost. In such cases, treatment may be seen as constituting a ‘harm’ rather than a ‘bene?t’.

The importance accorded to ethics in daily practice has undergone considerable development in the latter half of the 20th century. From being seen mainly as a set of values passed on from experienced practitioners to their students at the bedside, medical ethics have increasingly become the domain of lawyers, academic philosophers and professional ethicists, although the role of experienced practitioners is still considered central. In the UK, law and medical ethics increasingly interact. Judges resolve cases on the basis of established medical ethical guidance, and new ethical guidance draws in turn on common-law judgements in individual cases. The rapid increase in specialised journals, conferences and postgraduate courses focused on ethics is testimony to the ever-increasing emphasis accorded to this area of study. Multidisciplinary practice has stimulated the growth of the new discipline of ‘health-care ethics’ which seeks to provide uniformity across long-established professional boundaries. The trend is to set common standards for a range of health professionals and others who may have a duty of care, such as hospital chaplains and ancillary workers. Since a primary function of ethics is to ?nd reasonable answers in situations where di?erent interests or priorities con?ict, managers and health-care purchasers are increasingly seen as potential partners in the e?ort to establish a common approach. Widely accepted ethical values are increasingly applied to the previously unacknowledged dilemmas of rationing scarce resources.

In modern debate about ethics, two important trends can be identi?ed. As a result of the increasingly high pro?le accorded to applied ethics, there is a trend for professions not previously subject to widely agreed standards of behaviour to adopt codes of ethical practice. Business ethics or the ethics of management are comparatively new. At the same time, there is some debate about whether professionals, such as doctors, traditionally subject to special ethical duties, should be seen as simply doing a job for payment like any other worker. As some doctors perceive their power and prestige eroded by health-care managers deciding on how and when to ration care and pressure for patients to exercise autonomy about treatment decisions, it is sometimes argued that realistic limits must be set on medical obligations. A logical implication of patient choice and rejection of medical paternalism would appear to be a concomitant reduction in the freedom of doctors to carry out their own ethical obligations. The concept of conscientious objection, incorporated to some extent in law (e.g. in relation to abortion) ensures that doctors are not obliged to act contrary to their own personal or professional values.... ethics

Extension

Extension is the process of straightening or stretching a limb. When used in the natural sense, it involves the contraction of the muscles opposing those used in FLEXION. In cases of fractured limbs (see BONE, DISORDERS OF – Bone fractures), extension is employed during the application of splints, in order to reduce the displacement caused by the fracture, and prevent movement of the broken ends of bone. It is e?ected by gently and steadily pulling upon the part of the limb beyond the fracture. Extension of a more permanent type is used in the after-treatment of some fractures, as well as in diseases of the spine, by placing the patient upon an inclined bed and a?xing weights to his or her lower limbs, or to his or her head by means of adhesive plaster or of straps.... extension

Extrasystole

Extrasystole is a term applied to premature contraction of one or more of the chambers of the heart. A beat of the heart occurs sooner than it should do in the ordinary rhythm and is followed by a longer rest than usual before the next beat. In an extrasystole, the stimulus to contraction arises in a part of the heart other than the usual. Extrasystoles often give rise to an unpleasant sensation as of the heart stumbling over a beat, but their occurrence is not usually serious.... extrasystole

Extravasation

An escape of ?uid from the vessels or passages which ought to contain it. Extravasation of blood due to tearing of vessel walls is found in STROKE, and in the commoner condition known as a bruise. Extravasation of urine takes place when the bladder or the URETHRA is ruptured by a blow on the abdomen or on the crutch (PERINEUM), or torn in a fracture of the pelvis. Intravenous infusions frequently extravasate.... extravasation

Hepatic Encephalopathy

A neuropsychiatric syndrome caused by disease of the LIVER, and occurring most often in patients with CIRRHOSIS – see also LIVER, DISEASES OF; it also occurs in acute form in acute failure of liver function. The disorder is believed to be the result of biochemical disturbance of brain function, because the condition is reversible and pathological changes in brain tissue are rarely found. The patient’s intellect, personality, emotions and consciousness are altered but neurological signs may or may not be identi?ed. Apathy, confusion, drowsiness, sometimes CONVULSIONS, speech disturbance and eventually COMA mark the progress of the condition. The principles of treatment are to remove the precipitating causes. These include: URAEMIA; sedative, antidepressant and hypnotic drugs; gastrointestinal bleeding; too much protein in the diet; infection; and trauma (including surgical operations).... hepatic encephalopathy

Physical Examination

That part of a patient’s consultation with a doctor in which the doctor looks, feels (palpates) and listens to (auscultates) various parts of the patient’s body. Along with the history of the patient’s symptoms, this enables the doctor to assess the patient’s condition and decide whether an immediate diagnosis is possible or whether laboratory or imaging investigations are needed to reach a diagnosis. A full physical examination may take 30 minutes or more. Physical examination, along with certain standard investigations, is done when a person attends for a ‘preventive’ check-up of his or her state of health.... physical examination

Pseudoxanthoma Elasticum

Myalgic Encephalomyelitis (me)

A syndrome in which various combinations of extreme fatiguability, muscle pain, lack of concentration, panic attacks, memory loss and depression occur. Its existence and causes have been the subject of controversy re?ected in the variety of names given to the syndrome: CHRONIC FATIGUE SYNDROME (CFS), post-viral fatigue syndrome, Royal Free disease, epidemic neuromyasthenia and Icelandic disease. ME often follows virus infections of the upper respiratory tract or gut, but it is not clear whether this is an association or cause-ande?ect. It may occur in epidemics or as individual cases. Physical examination shows no evidence of diagnosable disease and there is no diagnostic test – diagnosis usually being made by excluding other possible disorders. The sufferer usually recovers in time, although sometimes recovery may take many months or even years. The most severely affected may be bedridden and may need tube-feeding. There is no speci?c curative treatment, but symptomatic treatment such as resting in the early stages may help. Some experts believe that the illness has a psychological element, and sufferers have been treated with COGNITIVE BEHAVIOUR THERAPY. In 1998 the Chief Medical O?cer set up a multidisciplinary working group, including patients, to consider possible cures and treatments for ME/CFS. The report (2002) concluded that the disorder should be recognised as chronic and treatable, but there was no clear agreement on cause(s) and treatment(s). Meanwhile research continues, including a programme by the Centre of Disease Control in Atlanta, USA. Su?erers may ?nd it helpful to consult the ME Association.... myalgic encephalomyelitis (me)

Spongiform Encephalopathy

A disease of the neurological system caused by a PRION. Spongy degeneration of the BRAIN occurs with progressive DEMENTIA. Known examples of the disorder in humans are CREUTZFELDT-JAKOB DISEASE (CJD) and KURU. Among animals, scrapie in sheep and BOVINE SPONGIFORM ENCEPHALOPATHY (BSE) are caused by slow viruses. The latter has occurred as an outbreak in cattle over the past decade or so, probably as a result of cattle being fed processed o?al from infected animals. Some people have developed a form of CJD from eating infected beef.... spongiform encephalopathy

Tennis Elbow

The medical name for this condition is epicondylitis. The condition is characterised by pain and tenderness on the outside of the elbow and is the result of in?ammation in the TENDON that attaches the muscles which extend the elbow to the HUMERUS bone. Epicondylitis can be the result of playing a lot of tennis or other racquet sports, gardening, ‘do it yourself’ work, or any activity that constantly pulls the tendon at its point of attachment. Lifting heavy objects aggravates the condition. Treatment is resting the arm, ANALGESICS and/or NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS). Sometimes ULTRASOUND therapy may promote healing, but persistent severe pain may necessitate the local injection of CORTICOSTEROIDS. Rarely, surgery may be recommended to release the tendon.... tennis elbow

Vasa Efferentia

Vacuum Extractor

Also called a ventouse. The idea of the glass suction cup applied to the emerging head of the baby to assist in delivery was ?rst considered by Younge in 1706, but it was not until 1954 that the modern (ventouse) vacuum extractor was introduced. The value of the ventouse as against the FORCEPS has been disputed in di?erent clinics, the former being less popular in the UK. Indications are similar for the use of obstetric forceps. Even if the OCCIPUT is not in the anterior position, the extractor may still be applied; many obstetricians would choose forceps or perform manual rotation of the fetus in such cases.

In cases of prolongation of the ?rst stage of labour, the ventouse may be used to accelerate dilatation of the cervix – provided that the cervix is already su?ciently dilated to allow application of the cup. The ventouse cannot be applied to the breech or face; in urgent cases of fetal distress the operation takes too long, and forceps delivery is preferred. There is some doubt about its safety when used on premature babies; many obstetricians feel that forceps delivery reduces the risk of intracranial haemorrhage. The vacuum extractor, while resulting in a slower delivery than when forceps are used, has a lower risk of damage to the mother’s birth canal. (See PREGNANCY AND LABOUR – Some complications of labour.)... vacuum extractor

Zollinger-ellison Syndrome

A rare disorder in which severe peptic ulcers recur in the stomach and duodenum (see DUODENAL ULCER; STOMACH, DISEASES OF). It is caused by a tumour in the PANCREAS that produces a hormone, GASTRIN, which stimulates the stomach and duodenum to produce excess acid: this causes ulceration.

The deliberate obstruction of a blood vessel in order to stop

internal bleeding or to cut off the blood supply to a tumour. In the latter case, the technique can relieve pain; cause the tumour to shrivel, making surgical removal easier; or stop the tumour from spreading. Embolization can also be used to block flow through vascular abnormalities such as haemangiomas both in the skin and the internal organs. A catheter is introduced into a blood vessel near the one to be blocked and the embolus that will block the vessel is released through the catheter.

Earwax

A yellow or brown secretion, also called cerumen, produced by glands in the outer ear canal. Some people produce so much wax that it regularly obstructs the canal. Excess earwax may produce a sensation of fullness in the ear and partial deafness. Prolonged blockage may irritate the canal.Wax that causes blockage or irritation may come out after being softened with oil. Otherwise, it should be removed by a doctor. This is usually done, after wax is softened, by syringing of the ears. eating disorders Illnesses characterized by obsessions with weight and body image. Eating disorders are most common in young adolescent females but can affect males. In anorexia nervosa, patients, despite being painfully thin, perceive themselves as fat and starve themselves.

Elbow

The hinge joint formed where the lower end of the humerus meets the upper ends of the radius and ulna. The elbow is stabilized by ligaments at the front, back, and sides. It enables the arm to be bent and straightened, and the forearm to be rotated through almost 180 degrees around its long axis without more than very slight movement of the upper arm.

Disorders of the elbow include arthritis and injuries to the joint and its surrounding muscles, tendons, and ligaments. Repetitive strain on the tendons of the muscles of the forearm, where they attach to the elbow, can result in an inflammation that is known as epicondylitis. There are 2 principle types of epicondylitis: tennis elbow and golfer’s elbow. Alternatively, a sprain of the ligaments may occur. Olecranon bursitis develops over the tip of the elbow in response to local irritation. Strain on the joint can produce an effusion or traumatic synovitis. A fall on to the hand or on to the elbow can cause a fracture or dislocation.elderly, care of the Appropriate care to help minimize physical and mental deterioration in the elderly. For example, failing vision and hearing are often regarded as inevitable in old age, but removal of a cataract or use of a hearing-aid can often improve quality of life. Isolation or inactivity leads to depression in some elderly people. Attending a day-care centre can provide social contact and introduce new interests.

Many elderly people are cared for by family members. Voluntary agencies can often provide domestic help to ease the strain on carers. Sheltered housing allows independence while providing assistance when needed. Elderly people who have dementia or physical disability usually require supervision in a residential care or hospital setting. (See also geriatric medicine.)... elbow

Eustachian Tube

The passage that runs from the middle ear into the back of the nose, just above the soft palate. The tube acts as a drainage channel from the middle ear and maintains hearing by opening periodically to regulate air pressure. The lower end of the tube opens during swallowing and yawning, allowing air to flow up to the middle ear, equalizing the air pressure on both sides of the eardrum.

When a viral infection such as a cold causes blockage of the eustachian tube, equalization cannot occur, resulting in severe pain and temporary impairment of hearing. A person with a blocked eustachian tube who is subjected to rapid pressure changes may suffer from barotrauma. Glue ear or chronic otitis media may occur if the tube is blocked, preventing adequate drainage from the middle ear. These conditions, which often result in partial hearing loss are more common in children. This is partly because their adenoids are larger and more likely to cause a blockage if they become infected and partly because children’s eustachhian tubes are shorter than those of adults.... eustachian tube

Ewing’s Sarcoma

A rare malignant form of bone cancer. It arises in a large bone, usually the femur, tibia, humerus, or a pelvic bone, and spreads to other areas at an early stage. The condition is most common in children aged 10–15. An affected bone is painful and tender. It may also become weakened and fracture easily. Other symptoms include weight loss, fever, and anaemia.

The sarcoma is diagnosed by X-rays and a biopsy.

If cancer is found, the whole skeleton is examined by X-rays and radionuclide scanning, and the lungs viewed by CT scanning, to determine if, and how far, the cancer has spread.

Treatment is with radiotherapy and anticancer drugs.

If the cancer has not spread, the outlook is good.... ewing’s sarcoma

Exotropia

Eyelid

A fold of tissue at the upper or lower edge of an eye socket.

The eyelids are held in place by ligaments attached to the socket’s bony edges.

They consist of thin plates of fibrous tissue (called tarsal plates) covered by muscle and a thin layer of skin.

The inner layer is covered by an extension of the conjunctiva.

Along the edge of each lid are two rows of eyelashes.

Immediately behind the eyelashes are the openings of the ducts leading from the meibomian glands, which secrete the oily part of the tear film.

The lids act as protective shutters, closing as a reflex action if anything approaches the eye.

They also smear the tear film across the cornea.... eyelid

Golfer’s Elbow

A painful condition caused by inflammation of the epicondyle (bony prominence) on the inner elbow, at the site of attachment of some forearm muscles. Golfer’s elbow is caused by overuse of these muscles, which bend the wrist and fingers. Activities such as using a screwdriver or playing golf with a faulty grip can cause the condition. Treatment consists of resting the elbow, applying ice-packs, and taking analgesic drugs to relieve pain.

Accident And Emergency Medicine

Accident and Emergency Medicine is the specialty responsible for assessing the immediate needs of acutely ill and injured people. Urgent treatment is provided where necessary; if required, the patient’s admission to an appropriate hospital bed is organised. Every part of the UK has nominated key hospitals with the appropriately trained sta? and necessary facilities to deal with acutely ill or injured patients. It is well-recognised that prompt treatment in the ?rst hour or so after an accident or after the onset of an acute illness – the so-called ‘golden hour’ – can make the di?erence between the patient’s recovery and serious disability or death.

A&E Medicine is a relatively new specialty in the UK and there are still inadequate numbers of consultants and trainees, despite an inexorable rise in the number of patients attending A&E departments. With a similar rise in hospital admissions there is often no bed available immediately for casualties, resulting in backlogs of patients waiting for treatment. A major debate in the specialty is about the likely need to centralise services by downgrading or closing smaller units, in order to make the most e?cient use of sta?.

Anís De Estrella

Chinese star anise (Illicium verum).

Plant Part Used: Fruit, seed.

Dominican Medicinal Uses: The fruits or seeds are traditionally prepared as a decoction and taken orally for flatulence, headache, indigestion, stomach ache, upper respiratory tract infection and cleansing the intestines.

Safety: The fruit is generally considered safe for human consumption in small amounts and is widely used as a culinary spice. When taken in excessive quantities, isolated compounds from the fruit have shown neurotoxic effects in animal studies. Caution is advised due to possible adulteration with the highly poisonous look-alike, Japanese star anise (Illicium anisatum).

Contraindications: Avoid use in small children due to potential contamination with misidentified toxic look-alike. Caution and avoidance is advised in patients with a history of convulsive disorders including epilepsy due to case reports of seizures associated with internal use of the tea. Caution advised in patients prior to surgery due to potential risk of increased bleeding.

Drug Interactions: Anticoagulants, antiplatelet medications and NSAIDS: based on animal studies in mice, star anise increases cytochrome P450 dependent 7-ethoxycoumarin O-deethylase activity which may affect the metabolism of these drugs.

Clinical Data: No human clinical trials evaluating this plant species have been identified in the available literature.

Laboratory & Preclinical Data: The following biological activities of this plant have been demonstrated in laboratory and preclinical studies using in vitro or animal models: antiangiogenic, antibacterial, antimicrobial, insecticidal, neurotropic and sepsis prevention.

Ebola Virus Disease

Ebola virus disease is another name for VIRAL HAEMORRHAGIC FEVER. The ebola virus is one of the most virulent micro-organisms known. Like the marburg virus (see MARBURG DISEASE), it belongs to the ?lovirus group which originates in Africa. Increased population mobility and wars have meant that the infection occasionally occurs elsewhere, with air travellers developing symptoms on returning home.

Treatment As the disease can be neither prevented nor cured, treatment is supportive, with strict anti-infection procedures essential as human-to-human transmission can occur via skin and mucous-membrane contacts. Incubation period is 5–10 days. Fever with MYALGIA and headache occur initially, often accompanied by abdominal and chest symptoms. Haemorrhagic symptoms soon develop and the victim either starts to improve in the second week or develops multi-organ failure and lapses into a coma. Mortality ranges from 25 to 90 per cent.... ebola virus disease

Discover More About Earl Grey Tea

If you’re a fan of black tea, you must have heard of the Earl Grey tea. If not, this is your chance to find out all you need to know about this richly-flavored black tea. Read about its health benefits and side effects, as well. About Earl Grey tea Earl Grey tea is one of the most popular types of black tea, drunk by people all around the world. It has a refreshing, citrusy flavor thanks to the bergamot orange oil added in its composition. The bergamot orange is the fruit of a citrus tree which blooms during winter; it is commercially cultivated in Italy. The bergamot oil, which is responsible for the tea’s citrusy flavor, is extracted from the skin of the fruit. In America, it is sometimes misspelled as “Earl Gray”. However, this is not the generally accepted spelling of the tea’s name. The Earl Grey tea is often drank during breakfast or brunch. It makes a good team with different sweets and pastries.  It is also used to add flavor to various types of cakes. History of Earl Grey tea The Earl Grey tea is named after Charles Grey, 2nd Earl of Britain, who was Prime Minister during the 1830s. As to why it was named after him, one legend says that a Chinese merchant gave this tea to Lord Grey to show his gratefulness, as one of the lord’s men had saved his son from drowning. However, there are doubts related to the authenticity of this story, as Lord Grey had never been to China, and the Chinese hadn’t yet discovered about the use of bergamot oil as a tea ingredient. It is possible that, seeing as Earl Grey tea was discovered at the beginning of the 19th century, it was simply named after a politician who was quite well-known at that time. According to the Grey family, Lady Grey served Earl Grey tea to various guests. As it became more and more popular, she was asked if the Earl Grey tea could be sold. This is how it became a brand of the Twinings tea company. Varieties of Earl Grey tea Considering how popular the Earl Grey tea is, it isn’t surprising that there are currently quite a few varieties of this tea. One of the well-known varieties of Earl Grey tea is Lady Grey, named after Mary Elizabeth Grey, the wife of Lord Grey. Other flavors are added to the usual Earl Grey tea. Some varieties of Lady Grey include adding blue cornflower blossoms, lavender or Seville oranges. Another type of the Earl Grey tea is the Russian Earl Grey. To the usual ingredients, it adds citrus peels, vodka, and lemon grass. Other types of Earl Grey tea include flowers among its ingredients. One of them is the French Earl Grey, which uses rose petals. There are some types of Earl Grey tea where the usual black tea leaves are replaced with something else. One example is Earl Grey Green, where the bergamot oil is combined with green leaves instead of the black ones. Another example is Rooibos Earl Grey, possibly originating from Malaysia. In this case, the black leaves are replaced with Rooibos, a South-African herbal plant. Also, in various coffee shops and tea shops, you can find a drink called London Fog. It is a “tea latte” and its ingredients are Earl Grey tea, steamed milk and vanilla syrup. How to prepare Earl Grey Tea For a cup of Earl Grey tea, use one teaspoon of tea leaves, or one regular-sized teabag. Boil the water before pouring it into the cup, and then let it steep for about 5 minutes. Then, remove the tea leaves or teabag. Based on your preferences, you can add sugar, lemon or milk to your cup of Earl Grey tea. Benefits of Earl Grey Tea The Earl Grey tea comes with many health benefits, both thanks to the black tea leaves and the bergamot oil. First, the antioxidants in its composition strengthen your immune system. They help keep your body young and healthy, protecting it from various viruses. This is why people who have caught a cold or the flu, or simply have a fever, drink Earl Grey tea. The Earl Grey tea has a calming effect thanks to the bergamot oil in its composition. It helps improve your mood by fighting against anxiety, depression, stress, and mood swings. The bergamot oil in the Earl Grey tea also helps you with digestion. It’s useful when suffering from indigestion, nausea and colic. It is also recommended in the case of urinary tract infections and intestinal problems. Earl Grey tea also helps you maintain a good oral hygiene. It fights against tooth decay and oral infections, and keeps the cavities away. Side effects of Earl Grey tea Despite its many health benefits, consumption of Earl Grey tea can have a few side effects, as well. The caffeine found in the composition of Earl Grey tea can affect you negatively, especially if caffeine isn’t good for your body.  To some people it may induce anxiety and heart palpitations. It can also increase blood pressure, making it bad for people who already have a high blood pressure. Also, if you drink a large amount of Earl Grey tea for a long time and suddenly, you stop, you might experience caffeine withdrawal symptoms. They include headaches that can last for up to a week, difficulty in concentrating, nausea, depression and anxiety. Drinking a large amount of Earl Grey tea can lead to side effects, as well. You might end up suffering from headaches, loss of appetite, vomiting, diarrhea, insomnia, dizziness, and irregular heartbeats. Therefore, make sure you don’t drink more than six cups of any tea, including Earl Grey tea.   Stay healthy by drinking this rich and citrusy-flavored black tea, the Earl Grey tea. Keep an eye on the side effects, but don’t let them scare you, as there are many more health benefits. So relax and enjoy your cup of Earl Grey tea with some cookies!... discover more about earl grey tea

Eating Disorders

The term ‘eating disorders’ covers OBESITY, feeding problems in childhood, anorexia nervosa, and bulimia nervosa. The latter two are described here.

Anorexia nervosa Often called the slimmer’s disease, this is a syndrome characterised by the loss of at least a quarter of a person’s normal body weight; by fear of normal weight; and, in women, by AMENORRHOEA. An individual’s body image may be distorted so that the sufferer cannot judge real weight and wants to diet even when already very thin.

Anorexia nervosa usually begins in adolescence, affecting about 1–2 per cent of teenagers and college students at any time. It is 20 times more common among women than men. Up to 10 per cent of sufferers’ sisters also have the syndrome. Anorexia may be linked with episodes of bulimia (see below).

The symptoms result from secretive self-starvation, usually with excessive exercise, self-induced vomiting, and misuse of laxatives. An anorexic (or anorectic) person may wear layers of baggy clothes to keep warm and to hide the ?gure. Starvation can cause serious problems such as ANAEMIA, low blood pressure, slow heart rate, swollen ankles, and osteoporosis. Sudden death from heart ARRHYTHMIA may occur, particularly if the sufferer misuses DIURETICS to lose weight and also depletes the body’s level of potassium.

There is probably no single cause of anorexia nervosa. Social pressure to be thin seems to be an important factor and has increased over the past 20–30 years, along with the incidence of the syndrome. Psychological theories include fear of adulthood and fear of losing parents’ attention.

Treatment should start with the general practitioner who should ?rst rule out other illnesses causing similar signs and symptoms. These include DEPRESSION and disorders of the bowel, PITUITARY GLAND, THYROID GLAND, and OVARIES.

If the diagnosis is clearly anorexia nervosa, the general practitioner may refer the sufferer to a psychiatrist or psychologist. Moderately ill sufferers can be treated by COGNITIVE BEHAVIOUR THERAPY. A simple form of this is to agree targets for daily calorie intake and for acceptable body weight. The sufferer and the therapist (the general practitioner or a member of the psychiatric team) then monitor progress towards both targets by keeping a diary of food intake and measuring weight regularly. Counselling or more intensely personal PSYCHOTHERAPY may help too. Severe life-threatening complications will need urgent medical treatment in hospital, including rehydration and feeding using a nasogastric tube or an intravenous drip.

About half of anorectic sufferers recover fully within four years, a quarter improve, and a quarter remain severely underweight with (in the case of women) menstrual abnormalities. Recovery after ten years is rare and about 3 per cent die within that period, half of them by suicide.

Bulimia nervosa is a syndrome characterised by binge eating, self-induced vomiting and laxative misuse, and fear of fatness. There is some overlap between anorexia nervosa and bulimia but, unlike the former, bulimia may start at any age from adolescence to 40 and is probably more directly linked with ordinary dieting. Bulimic sufferers say that, although they feel depressed and guilty after binges, the ‘buzz’ and relief after vomiting and purging are addictive. They often respond well to cognitive behaviour therapy.

Bulimia nervosa does not necessarily cause weight loss because the binges – for example of a loaf of bread, a packet of cereal, and several cans of cold baked beans at one sitting – are cancelled out by purging, by self-induced vomiting and by brief episodes of starvation. The full syndrome has been found in about 1 per cent of women but mild forms may be much more common. In one survey of female college students, 13 per cent admitted to having had bulimic symptoms.

Bulimia nervosa rarely leads to serious physical illness or death. However, repeated vomiting can cause oesophageal burns, salivary gland infections, small tears in the stomach, and occasionally dehydration and chemical imbalances in the blood. Inducing vomiting using ?ngers may produce two tell-tale signs – bite marks on the knuckles and rotten, pitted teeth.

Those suffering from this condition may obtain advice from the Eating Disorders Association.... eating disorders

They are particularly dangerous when they infect premature infants, and there have been several outbreaks of such infection in neonatal units, in which premature infants and other seriously ill small babies are nursed. The virus is introduced to such units by mothers, sta? and visitors who are unaware that they are carriers of the virus.... echoviruses

Eclectics

The name commonly applied to the American School Physicians, a distinct group of Medical Doctors who trained in their own schools, and were licensed as M.D.s. They specialized in low-tech, nonhospital rural health care...the famous country doc with a black bag. Besides standard medical procedures, they used a more wholistic approach to disease, sometimes terming themselves Vitalists. They were the most sophisticated of the many movements that arose in response to the almost maniac medical practices of the first half of the 19th century, especially in the United States, where, as always, medicine was philosophically invasive and heroic (often a wonderment to visiting physicians from Paris or London) The Eclectics flourished and grew out of the settlement and usurpment of the Ohio and Missouri Valleys, with a sparse population and no organized hospitals, relied on methods that were not invasive (unless emergencies dictated), used therapies that relied on strengthening natural resistance (no hospitals, just someone’s sod hut) and made particular care to explain and prepare the family or neighbors for THEIR part in caring for the patient...long after the physician left. Scudder, John King, Felter, Ellingwood and Clyce Wilson were some of the more famous Eclectics, and John Uri Lloyd was the most famous pharmacist/pharmacologist within the profession. The Eclectic movement lasted from 1840 to 1937...when the only remaining medical school, unwilling to change to a Flexner Curriculum (as had the other survivors) closed its doors in Cincinnati. Long operating in a tradition of radical, populist and anti­establishment philosophy, they were unable to get any public funding, were unable to ally themselves with full universities (and share faculty and funding), and were unable to expand their teaching facilities with only a base of tuition income. They lost the licensing wars and are no more. Their tradition was exported by practitioners in Germany and Mexico, and the German Eclectics, transformed by that peculiar culture into wild-eyed Nature Curists such as Ehret, Mausert and Lust, started the nucleus for the Naturopathic movement in Yellow Springs, Ohio (next-door to Goddard College) in 1947, helping to found the initial form of the National College of Naturopathic Medicine...10 years after, and 50 miles away from the last Eclectic Medical School. Without benefit of Tanna Leaves or Charleton Heston and an armful of pickled mummy-organs, Eclectecism was reborn into the body of Naturopathy. See: THOMSONIANS... eclectics

Eisenmenger Syndrome

A condition in which the subject suffers from a defect in one of the dividing walls (septum) of the HEART and this is accompanied by PULMONARY HYPERTENSION. The defect allows blood low in oxygen to ?ow from the right to the left side of the heart and be pumped into the aorta, which normally carries oxygenated blood to the body. The patient has a dusky blue appearance, becomes breathless and has a severely restricted exercise tolerance. There is an increase in red blood cells as the body attempts to compensate for the lowered oxygen delivery. The condition may be avoided by early surgical repair of the septal defect, but once it is evident, surgery may not be possible.... eisenmenger syndrome

Elderberry

Sambucus canadensis

Description: Elderberry is a many-stemmed shrub with opposite, compound leaves. It grows to a height of 6 meters. Its flowers are fragrant, white, and borne in large flat- topped clusters up to 30 centimeters across. Its berrylike fruits are dark blue or black when ripe.

Habitat and Distribution: This plant is found in open, usually wet areas at the margins of marshes, rivers, ditches, and lakes. It grows throughout much of eastern North America and Canada.

Edible Parts: The flowers and fruits are edible. You can make a drink by soaking the flower heads for 8 hours, discarding the flowers, and drinking the liquid.

CAUTION

All other parts of the plant are poisonous and dangerous if eaten.... elderberry

Elderberry Tea - A Natural Flu Fighter

Elderberry tea is commonly known as a remedy for flu or cold. This miraculous shrub has many other benefits for your health and can be used in many forms even for wines or sweets. About Elderberry tea Originally native to Europe and Western Africa, elderberry is a bush with white flowers and clusters of berries that are purplish to black in color. The best type of elderberry is considered to be the sambucus nigra, because it is truly the only safe type. Other types can be poisonous (especially stems and leaves) so be careful when you pick it yourself or when you buy it from stores. The elderberry flowers and fruits are usually used to prepare teas, wine, jams, pies and syrups and are sometimes used as flavoring for soft drinks. The elderberry plant is also sometimes used as an ornamental plant. Elderberry tea is rich in vitamin C and has high levels of flavonoids, anthocyanin, sambucin, sambunigrin and potassium nitrate, along with sugars. Only dried white flowers are used to prepare the tea which has a delicate tasty flavor. How to prepare Elderberry tea For a delicious cup of Elderberry tea, take 3 teaspoons of dried flowers and combine them with a cup of boiling water. Let them steep for approximately 10 minutes. Cool, strain and enjoy it afterwards. The same procedure must be followed if you use teabags, but use only 1. Drink it up to three times a day to treat flu or other respiratory conditions. If you add honey, its benefits will be doubled. Benefits of Elderberry tea Elderberry tea has lots of benefits especially when it comes to flu or fever. It helps relieving respiratory conditions caused by a buildup of mucus or phlegm, such as colds, bronchitis, and asthma problems. It clears the system out, lowers fever and eases flu symptoms. Elderberry tea also acts as an antioxidant protecting the body against aging free radicals thanks to the flavonoids contained. It has also a detoxifying effect helping the liver and kidneys to process and remove toxins from the body. Elderberry tea may help in the treatment of various types of allergies. Elderberry tea may be helpful in the quick recovery of patients with eruptive diseases caused by viruses like measles and chicken pox. It is also recommended in the treatment of arthritic and rheumatic pain. Side effects of Elderberry tea Although Elderberry tea is considered generally safe, it can occasionally generate  some side effects like gastrointestinal upset. Please keep in mind that it is always a good idea to ask your physician’s opinion before taking this tea if you are pregnant or breastfeeding. As you can see, Elderberry tea has many benefits for your health and as long as you have chosen the right type and you do not exceed 3 cups a day you can drink it with no worries.... elderberry tea - a natural flu fighter

Electrical Injuries

These are usually caused by the passage through the body of an electric current of high voltage owing to accidental contact with a live wire or to a discharge of lightning. The general effects produced are included under the term electric shock, but vary greatly in degree. The local effects include spasmodic contraction of muscles, fracture of bones, and in severe cases more or less widespread destruction of tissues which may amount simply to burns of the skin or may include necrosis of masses of muscle and internal organs. Fright due to the unexpectedness of the shock, and pain due to the sudden cramp of muscles, are the most common symptoms and in most cases pass o? within a few minutes. In more severe cases – especially when the person has remained in contact with a live wire for some time, or has been unable to let go of the electrical contact owing to spasmodic contraction of the muscles – the effects are more pronounced and may include concussion or compression of the brain (see BRAIN, DISEASES OF). In still more severe cases, death may ensue either from paralysis of the respiration or stoppage of the heart’s action. If prompt measures are taken for treatment, the victim can often be resuscitated.

In Britain there are an average of 110 deaths a year from electrocution, half of these occurring in the home.

Treatment No electrical apparatus or switch should be touched by anyone who is in metallic contact with the ground, such as through a metal pipe, especially, for example, from a bath. The ?rst action is to break the current. This can sometimes be done by turning o? a switch. If the victim is grasping or in contact with a live wire, the contact may be severed with safety only by someone wearing rubber gloves or rubber boots; but as these are not likely to be immediately available, the rescuer’s hands may be protected by a thick wrapping of dry cloth, or the live wire may be hooked or pushed out of the way with a long wooden stick such as a broom-handle. If the injured person is unconscious, and especially if breathing has stopped, arti?cial respiration should be applied as described in APPENDIX 1: BASIC FIRST AID – Electrocution. When the patient begins to breathe again, he or she must be treated for shock and professional help obtained urgently.... electrical injuries

Electrocardiogram (ecg)

A record of the variations in electric potential which occur in the HEART as it contracts and relaxes. Any muscle in use produces an electric current, but when an individual is at rest, the main muscular current in the body is that produced by the heart. This can be recorded by connecting the outside of the body by electrodes with an instrument known as an electrocardiograph. The patient is connected to the electrocardiograph by leads from either the arms and legs or di?erent points on the chest. The normal electrocardiogram of each heartbeat shows one wave corresponding to the activity of the atria and four waves corresponding to the phases of each ventricular beat. Various readily recognisable changes are seen in cases in which the heart is acting in an abnormal manner, or in which one or other side of the heart is enlarged. This record therefore forms a useful aid in many cases of heart disease (see HEART, DISEASES OF). The main applications of the electrocardiogram are in the diagnosis of myocardial infarction and of cardiac ARRHYTHMIA.

Electrocardiography

A method of recording the electrical activity of the heart muscles. Electrodes from a recording machine (electrocardiograph) are placed on the skin of the chest wall, arms and legs. The record of the electrical changes is called an ECG (electrocardiogram). The number of electrodes used depends on the complexity of the heart disorder being monitored. The procedure can be done in hospital, doctors’ surgeries and the patient’s home, and should not cause any discomfort.

In certain circumstances – for example, where a person has had bouts of chest pain – an exercise ECG may be performed under medical supervision. The patient walks on a treadmill while the ECG is recorded continuously.... electrocardiogram (ecg)

Electroconvulsive Therapy (ect)

A controversial but sometimes rapidly e?ective treatment for cases of severe DEPRESSION, particularly where psychotic features are present (see PSYCHOSIS), or in high-risk patients such as suicidal or post-partum patients. ECT is only indicated after antidepressants have been tried and shown to be ine?ective; the full procedure of treatment should be explained to the patient, whose consent must be obtained.

Before treatment, the patient will have been fasted for at least eight hours. After checking for any potential drug ALLERGY or interactions, the patient is given a general anaesthetic and muscle relaxants. Depending on the side of the patient’s dominance, either unilateral (on the side of the non-dominant hemisphere of the BRAIN) or bilateral (if dominance is uncertain,

e.g. in left-handed people) positioning of electrodes is used. Unilateral ECT has the advantage of being associated with less anterograde AMNESIA. When the current passes, the muscles will contract for approximately 10 seconds, with further tonic spasms lasting up to a minute. The patient should then be put in the COMA or recovery position and observed until fully conscious. Up to 12 treatments may be given over a month, improvement usually showing after the third session. Widely used at one time, the treatment is now given only rarely. It can be extremely frightening for patients and relatives and is not recommended for children.... electroconvulsive therapy (ect)

Electronic Monitoring Devices

Electronically driven equipment that will constantly monitor the physiological status of patients and the effects of medical intervention on that status. Such devices should relieve hospital sta? of time-consuming ‘human monitoring’ procedures and in some instances will enable patients to carry monitoring devices during their daily living activities. An example would be the regular assessment of blood-sugar concentration in subjects with DIABETES MELLITUS or the routine checking on the blood or tissue concentrations of administered drugs.... electronic monitoring devices

Electroencephalography (eeg)

In the BRAIN there is a regular, rhythmical change of electric potential, due to the rhythmic discharge of energy by nerve cells. These changes can be recorded graphically and the ‘brain waves’ examined – a procedure introduced to medicine in the 1920s. These records

– electroencephalograms – are useful in DIAGNOSIS: for example, the abnormal electroencephalogram occurring in EPILEPSY is characteristic of this disease. The normal waves, known as alpha waves, occur with a frequency of 10 per second. Abnormal waves, with a frequency of 7 or fewer per second, are known as delta waves and occur in the region of cerebral tumours and in the brains of epileptics. An electroencephalogram can assess whether an individual is awake, alert or asleep. It may also be used during surgery to monitor the depth of unconsciousness in anaesthetised patients.... electroencephalography (eeg)

Active principles are found to be oestrogenic and weakly progestogenic. Root—bechic, antidiarrhoeal. Seed—spermicidal, oxytocic, diuretic. The plant is also used for its blood purifying properties. It is an ingredient in cough syrups, preparations for anaemia, genitourinary tract infections, diarrhoea and diseases of the liver.

Embelin, isolated from the berries, shows significant anti-implantation and post-coital antifertility activity. (Successful trials have been carried out at the National Institute of Immunology, New Delhi on human beings.) It is found to be a potential male antifer- tility agent. Spermatogenesis has been impaired and sperm count reduced to the level of infertility. The antisper- matogenic changes are found to be reversible without any toxic effects.

Aqueous and EtOH extract of the fruit—anthelmintic against earthworms. Fruit powder (200 mg/kg), taken with curd on empty stomach, expelled tapeworm within 6-24 h. The treatment was also found effective in giardiasis. EtOH (50%) of the plant was found slightly active against E.coli. Di-salts of embelin—an- thelmintic. Amino salts exhibited less side effects than embelin. The effect of di-isobutyl amino derivatives lasted up to 10 h, also showed anti-inflammatory, hypotensive and antipyretic activities.

Berries gave quinones—embelin, ra- panone, homoembelin, homorapnone and vilangin.

Dosage: Fruit—5-10 g powder. (API Vol. I.)... embelia ribes

Siddha/Tamil: Nellikkaai, Nelli.

Action: Fruit—antianaemic, anabolic, antiemetic, bechic, astringent, antihaemorrhagic, antidiarrhoeal, diuretic, antidiabetic, carminative, antioxidant. Used in jaundice, dyspepsia, bacillary dysentery, eye trouble and as a gastrointestinal tonic. Juice with turmeric powder and honey is prescribed in diabetes insipidus. Seed—antibilious, antiasthmatic. Used in bronchitis. Bark—astringent. Leaf—juice is given in vomiting.

A decoction of powdered pericarp is prescribed for paptic ulcer.

Key application: As an antacid. (Indian Herbal Pharmacopoeia.).

The fruit is an important source of vitamin C, minerals and amino acids. The edible fruit tissue contains protein concentration threefold and vitamin C (ascorbic acid) concentration 160-fold than those of apple. The fruit also contains considerably higher concentration of most minerals and amino acids than apple.

The fruit gave cytokinine-like substances identified as zeatin, zeatin ribo- side and zeatin nucleotide; suspension culture gave phyllembin. Phyllem- bin exhibits CNS depressant and spasmolytic activity, potentiates action of adrenaline and hypnotic action of Nembutal.

The leaves contain gallic acid (10.8 mg/g dry basis), besides ascorbic and music acid. The methanol extract of the leaves is found to be effective in rat paw inflammation.

The bark contains tannin identified as mixed type of proanthocyanidin.

The fruit contains superoxide dis- mutase 482.14 units/g fresh weight and exhibits antisenescent (anti-aging) activity. Fruit, juice, its sediment and residue are antioxidant due to gallic acid. EtOH (50%) extract—antiviral.

Aqueous extract of the fruit increases cardiac glycogen level and decreases serum GOT, GPT and LDH in rats having induced myocardial necrosis.

Preliminary evidence suggests that the fruit and its juice may lower serum cholesterol, LDL, triglycerides and phospholipids without affecting HDL levels and may have positive effect on atherosclerosis. (Eur J clin Nutr, 42, 1988, 939-944; PhytotherRes, 14, 2000, 592-595.)

An aqueous extract of the fruit has been reported to provide protection against radiation-induced chromosomal damage in both pre-and postirradiation treatment. The fruit is reported to enhance natural killer cell activity and antibody dependent cellular cytotoxicity in mice bearing Dalton's lymphoma ascites tumour. The extract of the fruit and ascorbic acid prevented hepatotoxic and nephrotoxic effects induced by lead and aluminium. The toxicity could be counteracted to a great extent by the fruit extract than by an amount of ascorbic acid alone equivalent to that contained in fruits. (The fruit can be used as a dietary supplement to counteract prolonged exposure to metals in population in industrial areas.)

The fruits are reported to activate trypsin (proteolytic enzyme) activity.

The fruits can be used as coagulant in the treatment of water and can purify low turbidity water.

The fruits can be consumed safely all round the year.

Dosage: Fresh fruit—10-20 g; pulp juice—5-10 ml. (API Vol. I.)... emblica officinalis

Embrocations

Embrocations are mixtures, usually of an oily nature, intended for external application in cases of rheumatism, sprains, and other painful conditions. Their action is due mainly to the massage employed in rubbing in the embrocations, in part to the counter-irritant action of the drugs which they contain. (See LINIMENTS.)... embrocations

Embryo Research

When a woman is treated for infertility it is necessary to nurture human embryos for a few days (until the ?rst cell divisions of the fertilised egg have occurred) in a specialised laboratory. More eggs are fertilised than are usually needed because not all fertilisations are successful. Surplus embryos may be frozen for use in later attempts to implant an embryo in the womb. Research has been done on very early embryos but the practice is controversial and some countries have either forbidden it or imposed tight restrictions. In the UK such research is controlled by the government Human Fertilisation & Embryology Authority (see ASSISTED CONCEPTION).... embryo research

Emetics

An emetic is a substance which induces VOMITING (emesis). Emetics were previously used for gut decontamination in the treatment of poisoning but are now considered obsolete. This is because the e?cacy of emesis as a means of gut decontamination is unproved; there is a delay between administration and actual emesis, during which time continued absorption of the poison may occur; and some emetics have effects other than vomiting which may mask the clinical features of the ingested poison. The most commonly used emetic was syrup of ipecacuanha (ipecac). Salt (sodium chloride) water emetics were also used but there are many cases of fatal HYPERNATRAEMIA resulting from such use and salt water emetics should never be given. The most common method of gut decontamination currently used is the administration of activated CHARCOAL.... emetics

Encephalopathy (bse)

Known colloquially as ‘mad cow disease’, this is a fatal and untreatable disease. Along with scrapie in sheep and CREUTZFELDT-JACOB DISEASE (CJD) in humans, BSE belongs to a class of unusual degenerative diseases of the brain known as transmissible spongiform encephalopathies. The disease is caused by abnormal PRION proteins, which are resistant to cellular degradation. These abnormal prion proteins accumulate in and eventually cause the death of nerve cells, both in the spinal cord and the brain. The rare human disease CJD occurs throughout the world and is of three types: sporadic, iatrogenic (see IATROGENIC DISEASE) and inherited.

Since the BSE epidemic in cattle developed in the UK in the 1980s, however, a new variant of CJD has been identi?ed and is believed to be the result of consumption of the meat of BSE-infected cattle. Studies in transgenic mice have con?rmed that BSE caused variant CJD. The new variant has affected younger people and may have a shorter incubation period. If this incubation period turns out to be the same as for the other types of CJD, however, it could be 2005– 2010 before the peak of this outbreak is reached. Over 148 people had died, or were dying, from variant CJD in the UK by the year 2005.

The appearance of BSE in cattle is believed to have been caused by a gene mutation (see GENETIC DISORDERS), although whether this mutation ?rst occurred in cattle or in some other animal remains uncertain. Although the ?rst case of BSE was o?cially reported in 1985, the ?rst cattle are thought to have been infected in the 1970s. BSE spread to epidemic proportions because cattle were fed meat and bone meal, made from the o?al of cattle suffering from or incubating the disease. Mother-to-calf transfer is another likely route of transmission, although meat and bone meal in cattle feed were the main cause of the epidemic. The epidemic reached its peak in 1992 when the incidence of newly diagnosed cases in cattle was 37,545.

A two-year UK government inquiry into the BSE epidemic concluded that BSE had caused a ‘harrowing fatal disease in humans’, and criticised o?cials for misleading the public over the risk to humans from BSE. Consequently, a compensation package for patients and relatives was made available. Meanwhile, a ban on the export of UK beef and restrictions on the type of meat and products made from beef that can be sold to the public were put in place. Although initially thought to be a problem primarily con?ned to the UK, several other countries – notably France, Germany, Spain, Switzerland and the United States – have also discovered BSE in their cattle.... encephalopathy (bse)

Escop

European Scientific Cooperative for Phytotherapy. Established June 1989 by representatives of six European associations for phytotherapy. To advance the scientific status of phytomedicines (herbs) and to assist with harmonisation of their regulatory status at the European level. Represents about 1500 active members (physicians, pharmacists and scientists), many tens of thousands of prescribers and practitioners and many millions of consumers. This represents about 30 per cent of the entire pharmaceutical market.

Aims and objects. To develop a coordinated scientific framework to assess phytopharmaceuticals. To promote acceptance of phytopharmaceuticals, especially within the therapy of general medical practitioners. To support and initiate clinical and experimental research in phytotherapy. To improve and extend the international accumulation of scientific and practical knowledge.

National associations represented.

The Netherlands: Nederlandse Vereniging voor Fytotherapie.

Belgium: Socie?te? Belge de Phytothe?rapie, Belgische Vereniging voor Phytotherapie. France: Institut Francais de Phytothe?rapie.

United Kingdom: British Herbal Medicine Association.

Switzerland: Schweizerische Medizinische Gesellschaft fu?r Phytotherapie.

The Scientific Committee, with two delegates from each member country, has embarked on a programme of compiling proposals for European monographs on the medicinal uses of plant drugs. This task is expected to take about ten years to complete.

In preparing monographs the Committee assesses information from published scientific literature together with national viewpoints as expressed by delegates or included in the results of national reviews. Leading researchers on specific plant drugs are invited to relevant meetings and their contributions substantially assist the Committee’s work. Draft monographs prepared by the Scientific Committee are circulated for appraisal and comment to an independent Board of Supervising Editors, which includes eminent academic experts in the field of phytotherapy.

The monographs are offered to regulatory authorities as a means of harmonising the medicinal uses of plant medicines within the EC and in a wider European context. Phytotherapy (Herbalism) makes an important contribution to European medicine. ... escop

Essential Fatty Acids (efa)

A group of unsaturated fatty acids essential for growth and body function. EFA activity requires three polyunsaturated fatty acids (linolenic, linoleic and arachidonic). The most essential are linoleic and arachidonic which are closely involved in metabolism, transport of fats, and maintenance of cell membranes. While linolenic and arachidonic acids can be synthesised in the body, linoleic cannot.

EFA deficiency may be caused by alcohol, particularly Omega-6. Deficiencies may be responsible for a wide range of symptoms from foul-smelling perspiration to psoriasis, pre-menstrual tension and colic. EFAs are precursors of prostaglandin formation.

EFAs are present in oily fish and reduce the adhesion of platelets and the risk of heart disease. They reduce blood cholesterol and increase HDLs.

Common sources: cold pressed seeds, pulses, nuts and nut oils. Evening Primrose oil (15-20 drops daily). The best known source is Cod Liver oil (1-8 teaspoons daily); (children 1 teaspoon daily to strengthen immune system against infection); bottled oil preferred before capsules. To increase palatability pour oil into honey jar half filled with orange or other fruit juice, shake well and drink from the jar.

Margarines, salad dressings, cooking and other refined vegetable oils inhibit complete absorption of EFAs and should be avoided. EFAs require the presence of adequate supply of Vitamins A, B, C, D, E and minerals Calcium, Iron, Magnesium and Selenium. ... essential fatty acids (efa)

European Pharmacopoeia

Legal status of. Under the 1964 Convention on the Elaboration of a European Pharmacopoeia the standards of the European Pharmacopoeia are required to take precedence over the standards of the national pharmacopoeias of the contracting parties, thus ensuring a common standard.

Endotracheal Catheters Are Used To Pass

down the TRACHEA into the lungs, usually in the course of administering anaesthetics (see under ANAESTHESIA).

Eustachian catheters are small catheters that are passed along the ?oor of the nose into the Eustachian tube in order to in?ate the ear.

Nasal catheters are tubes passed through the nose into the stomach to feed a patient who cannot swallow – so-called nasal feeding.

Rectal catheters are passed into the RECTUM in order to introduce ?uid into the rectum.

Suprapubic catheters are passed into the bladder through an incision in the lower abdominal wall just above the pubis, either to allow urine to drain away from the bladder, or to wash out an infected bladder.

Ureteric catheters are small catheters that are passed up the ureter into the pelvis of the kidney, usually to determine the state of the kidney, either by obtaining a sample of urine direct from the kidney or to inject a radio-opaque substance preliminary to X-raying the kidney. (See PYELOGRAPHY.)

Urethral catheters are catheters that are passed along the urethra into the bladder, either to draw o? urine or to wash out the bladder.

It is these last three types of catheters that are most extensively used.... endotracheal catheters are used to pass

Endotracheal Intubation

Insertion of a rubber or plastic tube through the nose or mouth into the TRACHEA. The tube often has a cu? at its lower end which, when in?ated, provides an airtight seal. This allows an anaesthetist to supply oxygen or anaesthetic gases to the lungs with the knowledge of exactly how much the patient is receiving.

Enjoy A Cup Of Reishi Tea!

If you haven’t tried reishi tea until now, you should get some. Made from a “cure-all” herb, reishi tea has plenty of health benefits and helps you stay healthy with every gulp. About Reishi Tea Reishi tea is made form reishi, which is considered the best and most superior of all Chinese herbs. Reishi is a polypore mushroom which can be found growing in dark forests, on deciduous trees and logs. It is soft, corky, and flat, and has a conspicuous red-varnished cap, kidney-shaped, and with pores underneath it. It is classified based on its color and shape, and each variety protects and nourishes a different body organ. The classification is the following: white (lungs and skin), purple (joints), red (heart), green (liver), black (brain and kidney), and yellow (spleen). How to prepare Reishi Tea For a cup of reishi tea, you need about 5 grams of dried reishi mushroom herbs. Add them to the necessary amount of water for one cup and boil for about 10 minutes. Then, let the mixture steep for 2-3 hours, before you strain it to remove the herbs. If you don’t like the taste too much or you think it’s too bitter, you can add honey or fruit juice to sweeten it. Reishi Tea Constituents Reishi tea gets many of its health benefits thanks to the active constituents found in the reishi mushroom - the tea’s main ingredient. Some of them include triterpenes (ganoderic acids), polysaccharides, alkaloids, lactones, mannitol and coumarin. Also, reishi tea has various vitamins, proteins, and minerals. Reishi Tea Benefits Reishi tea is an important element in the fight against cancer. It helps by enhancing the human ability to fight abnormal cells and, consequently, it can improve the synthesis of proteins and nucleic acid. It also protects the cells against further damage, and it helps alleviate the pain and discomfort caused by chemotherapy. Drinking reishi tea will keep the heart diseases away, as it lowers bad cholesterol levels and blood pressure. It helps strengthen the immune system, and it will also slow down the aging process by nurturing the cells in your body. Not only is reishi tea good for your immune system, but it also helps your nervous system. This tea is bound to help you relax, by soothing the mind and sedating the nerves. It will also help you sleep properly during the night. You can drink reishi tea if you’ve got problems with coughing or asthma. It protects your liver, therefore it is recommended to persons who suffer from acute and chronic hepatitis. Besides this, it also helps with diabetes, skin allergy, and duodenal ulcers. Reishi Tea Side Effects You might have an allergic reaction to reishi tea. If you end up with an upset stomach, or you feel your mouth, nose and/or throat dry, you might have an allergic reaction. Stop drinking reishi tea and contact your doctor, just in case. Other side effects you might get when drinking reishi tea include dizziness, nosebleeds, sore bones, gastrointestinal distress, or irritated skin.

Environment And Health

Environment and Health concerns those aspects of human health, including quality of life, that are determined by physical, biological, social and psychosocial factors in the environment. The promotion of good health requires not only public policies which support health, but also the creation of supportive environments in which living and working conditions are safe, stimulating and enjoyable.

Health has driven much of environmental policy since the work of Edwin Chadwick in the early 1840s. The ?rst British public-health act was introduced in 1848 to improve housing and sanitation with subsequent provision of puri?ed water, clean milk, food hygiene regulations, vaccinations and antibiotics. In the 21st century there are now many additional environmental factors that must be monitored, researched and controlled if risks to human health are to be well managed and the impact on human morbidity and mortality reduced.

Environmental impacts on health include:

noise

air pollution

water pollution

dust •odours

contaminated ground

loss of amenities

vermin

vibration

animal diseases

Environmental risk factors Many of the major determinants of health, disease and death are environmental risk factors. Some are natural hazards; others are generated by human activities. They may be directly harmful, as in the examples of exposure to toxic chemicals at work, pesticides, or air pollution from road transport, or to radon gas penetrating domestic properties. Environmental factors may also alter people’s susceptibility to disease: for example, the availability of su?cient food. In addition, they may operate by making unhealthy choices more likely, such as the availability and a?ord-ability of junk foods, alcohol, illegal drugs or tobacco.

Populations at risk Children are among the populations most sensitive to environmental health hazards. Their routine exposure to toxic chemicals in homes and communities can put their health at risk. Central to the ability to protect communities and families is the right of people to know about toxic substances. For many, the only source of environmental information is media reporting, which often leaves the public confused and frustrated. To bene?t from public access to information, increasingly via the Internet, people need basic environmental and health information, resources for interpreting, understanding and evaluating health risks, and familiarity with strategies for prevention or reduction of risk.

Risk assessment Environmental health experts rely on the principles of environmental toxicology and risk assessment to evaluate the environment and the potential effects on individual and community health. Key actions include:

identifying sources and routes of environmental exposure and recommending methods of reducing environmental health risks, such as exposure to heavy metals, solvents, pesticides, dioxins, etc.

assessing the risks of exposure-related health hazards.

alerting health professionals, the public, and the media to the levels of risk for particular potential hazards and the reasons for interventions.

ensuring that doctors and scientists explain the results of environmental monitoring studies – for example, the results of water ?uoridation in the UK to improve dental health.

National policies In the United Kingdom in 1996, an important step in linking environment and health was taken by a government-initiated joint consultation by the Departments of Health and Environment about adding ‘environment’ as a key area within the Health of the Nation strategy. The ?rst UK Minister of State for Public Health was appointed in 1997 with responsibilities for health promotion and public-health issues, both generally and within the NHS. These responsibilities include the implementation of the Health of the Nation strategy and its successor, Our Healthy Nation. The aim is to raise the priority given to human health throughout government departments, and to make health and environmental impact assessment a routine part of the making, implementing and assessing the impact of policies.

Global environmental risks The scope of many environmental threats to human health are international and cannot be regulated e?ectively on a local, regional or even national basis. One example is the Chernobyl nuclear reactor accident, which led to a major release of radiation, the effects of which were felt in many countries. Some international action has already been taken to tackle global environmental problems, but governments should routinely measure the overall impacts of development on people and their environments and link with industry to reduce damage to the environment. For instance, the effects of global warming and pollution on health should be assessed within an ecological framework if communities are to respond e?ectively to potential new global threats to the environment.... environment and health

Ephedra Tea - The Energy Tea

With a reputation of an energy tea, Ephedra tea was taken by athletes and it is the subject of many controversies. Learn more about other benefits of this kind of tea. About Ephedra tea Ephedra, also known as Ma huang in Chinese, has been used in Chinese traditional medicine for centuries to treat cold related conditions. Botanically called Ephedra sinica, this is an evergreen shrub native to Asia. The plant’s leaves and stems are harvested, dried and then sold as teas, tinctures, extracts or tablets. The stems of ephedra have pungent and bitter taste and also diaphoretic, diuretic, pectoral, vasoconstrictive and vasodilative properties. The main chemical constituents in ephedra are ephedrine and pseudoephedrine which work by stimulating the nervous system, dilating bronchial tubes, elevating blood pressure, and increasing heart rate. Due to these effects, ephedra became a favorite for athletes as it is believed that the herb enhances athletic performance. Several incidences of adverse effects and even death that may have been caused by excessive consumption of ephedra and ephedra supplements led the Food and Drug Administration (FDA) to ban the sale of ephedra supplements in the United States in 2004. Currently, ephedra is still a subject of debate, especially when it comes to athletes in international competitions and anti-doping testes. However, don’t avoid Ephedra tea as it has important benefits as well. Ephedra tea preparation Ephedra tea can be made by placing about 10 grams of ephedra herb in 2 cups of water and let it boil for 10 minutes. Filter out the herbs before drinking the Ephedra tea. Ephedra tea benefits Here are several health benefits attributed to Ephedra tea. Ephedra Tea may alleviate respiratory ailments such asthma, colds, coughs and hay fever, as well as various allergic symptoms. Ephedra Tea may help expel exterior pathogens and regulate the proper functioning of the lungs. Ephedra Tea, taken in a regulated and supervised manner, may be effective for short-term weight loss, often associated with caffeine. Taken in a regulated and supervised manner, it stimulates the central nervous system may help boost energy and enhance alertness. Ephedra tea side effects Excessive use of Ephedra tea can cause dizziness, irregular heartbeat, seizures, strokes and even death. This tea is not recommended during pregnancy, breastfeeding and to persons with high blood pressure or heart disease. Ephedra tea should not be used as an energy booster, sports or diet aid or in combination with any stimulant such as caffeine as it may lead to unwanted side effects.

Epigenetics

The science of how the activity of DNA (deoxyribonucleic acid, which is the fundamental genetic material of cells) can be altered semi-permanently by chemical processes rather than by natural MUTATION. Genes contain instructions for making proteins. The natural process of implementing these instructions – gene expression – can be altered by chemical groups attaching themselves to the chemical bases that make up a strand of DNA. This, in turn, affects the generation of proteins from the genes so tagged. Some chemical groups can even stop a gene from being expressed. Recently, research in Australia showed that such a chemically induced alteration could be inherited, at least in mice. This points to the possibility that inherited epigenetic characteristics could cause ‘inherited diseases’ in the same way that natural genetic mutations do. These developments suggest that epigenetics will be an important part of genetic studies and research. Not all geneticists, however, believe that this developing aspect of genetics is so important and this debate will continue.... epigenetics

Ergot Poisoning

Ergot poisoning, or ergotism, occasionally results from eating bread made from rye infected with the fungus, Claviceps purpurea. Several terrible epidemics (St Anthony’s Fire), characterised by intense pain and hallucinations, occurred in France and Germany during the Middle Ages (see ERYSIPELAS). Its symptoms are the occurrence of spasmodic muscular contractions, and the gradual production of gangrene in parts like the ?ngers, toes and tips of the ears because of constriction of blood vessels and therefore the blood supply.... ergot poisoning

Erythrocytes

The biconcave red blood cells that carry oxygen from the lungs to the tissues, and return carbon dioxide (see also RESPIRATION). They have an excess of membrane, some of which may be lost in various disorders, as a result of which they become progressively more spherical and rigid. Erythrocytes, which have no nuclei, are formed during ERYTHROPOEISIS from ERYTHROBLASTS in the BONE MARROW, and each mm3 of blood contains 5 million of them. They are by far the largest constituent among the blood cells and they contain large amounts of the oxygen-carrier HAEMOGLOBIN. They have a life of about 120 days after which they are absorbed by macrophages (see MACROPHAGE), the blood’s scavenging cells. Most components of the erythrocytes, including the red pigment haemoglobin, are re-used, though some of the pigment is broken down to the waste product BILIRUBIN.... erythrocytes

Erythropoeisis

The process by which ERYTHROCYTES or red blood cells are produced. The initiating cell is the haemopoietic stem cell from which an identi?able proerythroblast develops. This goes through several stages as a normoblast before losing its nucleus to become an erythrocyte. This process takes place in the blood-forming bone-marrow tissue.... erythropoeisis

Ethics (of Care)

The basic evaluative principles which (should) guide “good” care. Principles typically refer to respect for, and the dignity of, human beings. Basic dimensions are “autonomy” (respect for self determination), “well-being” (respect for happiness, health and mental integrity) and “social justice” (justifiable distribution of scarce goods and services). More specifically, ethics of care refer to ethical standards developed for the care professions which are designed to implement ethical principles in the practice of care provision.... ethics (of care)

Ethics Committees

(In the USA, Institutional Review Boards.) Various types of ethics committee operate in the UK, ful?lling four main functions: the monitoring of research; debate of di?cult patient cases; establishing norms of practice; and publishing ethical guidance.

The most common – Local Research Ethics Committees (LRECs) – have provided a monitoring system of research on humans since the late 1960s. Established by NHS health authorities, LRECs were primarily perceived as exercising authority over research carried out on NHS patients or on NHS premises or using NHS records. Their power and signi?cance, however, developed considerably in the 1980s and 90s when national and international guidance made approval by an ‘appropriately constituted’ ethics committee obligatory for any research project involving humans or human tissue. The work of LRECs is supplemented by so-called ‘independent’ ethics committees usually set up by pharmaceutical companies, and since 1997 by multicentre research ethics committees (MRECs). An MREC is responsible for considering all health-related research which will be conducted within ?ve or more locations. LRECs have become indispensable to the conduct of research, and are doubtless partly responsible for the lack of demand in the UK for legislation governing research. A plethora of guidelines is available, and LRECs which fail to comply with recognised standards could incur legal liability. They are increasingly governed by international standards of practice. In 1997, guidelines produced by the International Committee on Harmonisation of Good Clinical Practice (ICH-GCP) were introduced into the UK. These provide a uni?ed standard for research conducted in the European Union, Japan and United States to ensure the mutual acceptance of clinical data by the regulatory authorities in these countries.

Other categories of ethics committee include Ethics Advisory Committees, which debate dif?cult patient cases. Most are attached to specialised health facilities such as fertility clinics or children’s care facilities. The 1990s have seen a greatly increased interest in professional ethics and the establishment of many new ethics committees, including some like that of the National Council for Hospice and Specialist Palliative Care Services which cross professional boundaries. Guidance on professional and ethical standards is produced by these new bodies and by the well-established ethics committees of regulatory or representative bodies, such as the medical and nursing Royal Colleges, the General Medical Council, United Kingdom Central Council for Nursing, Midwifery and Health Visiting, British Medical Association (see APPENDIX 8: PROFESSIONAL ORGANISATIONS) and bodies representing paramedics and professions supplementary to medicine. Their guidance ranges from general codes of practice to detailed analysis of single topics such as EUTHANASIA or surrogacy.

LRECs are now supervised by a central body

Eucalyptus Tea

Did you know that eucalyptus leaves are the favourite food of koala bears? Having a pungent scent and antimicrobial properties, eucalyptus is a well known remedy for sinusitis and other respiratory ailments. It is also used successfully in aromatherapy. About Eucalyptus Tea Eucalyptus is one of the quickest growing tree species on the planet and it is derived from the grayish-green, leathery leaves of the tree botanically known as Eucalyptus globulus, also called the “blue gum tree” or “Australian fever tree.” Native to Tasmania, the eucalyptus tree grows in subtropical zones worldwide. The leaves contain eucalyptol, as well as tannins, caffeic and gallic acids, also found in green tea, along with flavonoids and antioxidants. Eucalyptus is antiseptic, antiviral, antifungal and antispasmodic with expectorant and decongestant properties. Eucalyptus is primarily valuable for its leaves, which are used to make an essential oil, eucalyptus tea and compresses. If you want to enhance the scent of the leaves, due to the aromatic oils that are contained inside, all you have to do is break or crush them, and then this will be released. You can prepare eucalyptus tea either using dry or fresh leaves. However, Eucalyptus tea made of dried eucalyptus leaves has lost most of its healing power. Instead, it’s best to cut small branches with a few dozen fresh leaves and keep them in a vase with water to prevent drying. How to make Eucalyptus Tea To make eucalyptus tea, pour 1 cup of boiled water over up to 1/2 teaspoon of the dried eucalyptus leaves. Cover and steep for 10 minutes, then strain. You can sweeten with honey and drink up to 2 - 3 cups a day. If you want to use fresh leaves, take a single one, chop it, add hot water and let it steep for about 4-6 minutes - then add honey or brown sugar. The bits of leaf should then be strained and discarded. Take care not to ingest the eucalyptus oil directly, as it is extremely strong and somewhat volatile. Then drink in small sips while hot. Benefits of Eucalyptus Tea Some studies pointed out that drinking eucalyptus tea may help increase insulin production and lower blood sugar level. You can gargle this tea when you have throat infections, or use it as a mouthwash as its antiseptic and antibacterial properties fight bad breath. Eucalyptus tea, when rubbed in the chest area, may relieve bronchitis, asthma and colds. When inhaled, the steam from the eucalyptus tea can help alleviate chest infections and a host of respiratory and pulmonary ailments like colds, emphysema, whooping cough and asthma. Applied topically, the tea may produce healthier looking skin. A compress with eucalyptus tea is effective in treating painful joints, minor burns and sore muscles. Side effects of Eucalyptus Tea Side effects from eucalyptus tea are rare; nausea, vomiting and diarrhea have been reported. Consult your doctor before using eucalyptus tea. If you are pregnant, breastfeeding, if you have inflammation of the kidneys or that of the gastrointestinal tract, bile duct disease, liver disease or low or high blood pressure, don’t drink eucalyptus tea. Eucalyptus is a tree with many benefits and uses. Eucalyptus tea can easily be included in a healthy life style, especially when it is used to treat certain ailments.... eucalyptus tea

Although the likelihood of some form of evolution had been postulated by scientists in the late 18th and early 19th centuries, the prime contribution to the development of biological evolutionary doctrine came from the British scientist, Charles Darwin, who argued in his book The Origin of Species by Means of Natural Selection (1859) that natural selection resulted in the survival of the ?ttest organisms. The precise biological mechanism of evolution was not unravelled until the 20th century, with the discovery of CHROMOSOMES and GENES and the development of the science of genetics. Charles Darwin’s theory was based on his studies of the varied and unique animal life in the Galapagos Islands in the 19th century. He believed that the diversity of life on the planet could be ascribed to the combined effects of random variation in living things, inherited by succeeding generations.... evolution

Fagopyrum Esculentum

Moench.

Family: Polygonaceae.

Habitat: Native to Central Asia; now grown as minor grain-crop in hilly regions of North India and the Nilgiris.

English: Buckwheat.

Ayurvedic: Kotu.

Folk: Kutu, Phaapar.

Action: Used for treating fragile capillaries, chilbains and for strengthening varicose veins. Used at a supporting herb for treating high blood pressure. Rutin is obtained from fresh or dried leaves and flowers. (Rutin is used in a variety of haemorrhagic conditions.)

The seed are commonly used in colic, choleraic diarrhoea and abdominal obstructions. Root decoction is used in rheumatic pains, lung diseases and typhoid; juice in urinary disorders. In China, used in pulmonary sepsis.

The plant is used as a venous and capillary tonic, and for alleviating venous stasis and vericose veins.

Whole plant, dried or green, can cause photosensitization.... fagopyrum esculentum

Fibreoptic Endoscopy

A visualising technique enabling the operator to examine the internal organs with the minimum of disturbance or damage to the tissues. The procedure has transformed the management of, for example, gastrointestinal disease. In chest disease, ?breoptic bronchoscopy has now replaced the rigid wide-bore metal tube which was previously used for examination of the tracheo-bronchial tree.

The principle of ?breoptics in medicine is that a light from a cold light source passes down a bundle of quartz ?bres in the endoscope to illuminate the lumen of the gastrointestinal tract or the bronchi. The re?ected light is returned to the observer’s eye via the image bundle which may contain up to 20,000 ?bres. The tip of the instrument can be angulated in both directions, and ?ngertip controls are provided for suction, air insu?ation and for water injection to clear the lens or the mucosa. The oesophagus, stomach and duodenum can be visualised; furthermore, visualisation of the pancreatic duct and direct endoscopic cannulation is now possible, as is visualisation of the bile duct. Fibreoptic colonoscopy can visualise the entire length of the colon and it is now possible to biopsy polyps or suspected carcinomas and to perform polypectomy.

The ?exible smaller ?breoptic bronchoscope has many advantages over the rigid tube, extending the range of view to all segmental bronchi and enabling biopsy of pulmonary parenchyma. Biopsy forceps can be directed well beyond the tip of the bronchoscope itself, and the more ?exible ?breoptic instrument causes less discomfort to the patient.

Fibreoptic laparoscopy is a valuable technique that allows the direct vizualisation of the abdominal contents: for example, the female pelvic organs, in order to detect the presence of suspected lesions (and, in certain cases, e?ect their subsequent removal); check on the development and position of the fetus; and test the patency of the Fallopian tubes.

Mill.

Synonym: Solanum lycopersicum Linn.

Family: Solanaceae.

Habitat: Cultivated in many parts of India.

English: Tomato, Love Apple.

Unani: Tamaatar.

Action: Mild aperient, blood purifier, cholagogue, digestive. Used in homoeopathy for treating rheumatic conditions, colds, chills, digestive disorders, diabetes, obesity, leucorrhoea, metrorrhagia.

Tomato is a powerful deobstruent. It promotes flow of bile; mildly laxative, especially when taken raw. Tomato stimulates torpid liver and kidneys and helps to wash away toxins. Tomato is recommended for diabetics. It is a major dietary source of carotenoid lycopene.

Tomato juice inhibits carcinogenic N-nitrosocompound formation chiefly in the stomach. Most of the inhibition of formation of N-nitrosomorpholine by phenolic fraction of tomato juice was due to chlorogenic acids. The ascorbate fraction of the juice also contains compounds that inhibit ni- trosation.

Consumption of tomato juice can significantly increase serum lycopene levels. (Decreased serum lycopene concentrations are associated with an increase risk of prostate cancer.) (Natural Medicines Comprehensive Database, 2007.)

The alcoholic extract of tomato possesses CNS depressant and analgesic properties.... lycopersicon esculentum

(German Commission E.)

The leaves contain lithospermic acid. Plant contains luteolin-7-glucoside; ur- solic acid, caffeic acid, chlorogenic acid, sinapic acid, ellagic acid and other derivatives of phenolic acid. The antioxidant activity of the plant is partially attributed to rosmarinic acid. Antigonadotropic activity of the leaf extract is attributed to phenolic precursors.

Ethanol extract of the plant showed diverse effects on the pituitary, thyroid and gonadal glands of rats.

A closely related species, Lycopus virginicus of Europe, exhibits anti- thyrotropic activity. It induces TSH repletion in hypothyroid rats and reduction of TSH levels in euthyroid rats. Antigonadotropic activity has been demonstrated in rats.... lycopus europaeus

Maca Tea - A Libido Enhancer

Maca tea has been recognized for its nutritional properties and for being a libido enhancer. Maca plant, also known as the “Peruvian ginseng”, is an herb that grows in the high Andes of Bolivia and Peru for thousands of years. It is related to the turnip and the radish, having green and fragrant tops that lie along the ground. Maca has been used in Peru as a remedy to enhance energy and sexual function. The constituents of maca root are basically minerals such as calcium, potassium, magnesium, zinc, phosphorus and iron; sterols, lipids, carbohydrates, fiber, proteins and amino acids. How To Make Maca Tea Maca tea has a sweet taste, similar to butterscotch. To brew maca tea you will need an herbal tea of your choice to combine it with the maca powder. Prepare the herbal tea and after 1-2 minutes, add a teaspoon of maca powder and stir the mixture. To really enhance the flavor, you can add milk or honey. Tea connoisseurs recommend Soya milk. Maca Tea Benefits
  • Helps providing energy without over-stimulating the body’s systems.
  • Enhances libido and helps in the treatment of erectile dysfunction.
  • Increases the production of sperm.
  • Helps relieving the symptoms of menopause.
  • Strengthens your immune system.
  • Balances and stabilizes the body’s cardiovascular, nervous, muscular and lymphatic systems.
Maca Tea Side Effects In toxicity studies, maca tea showed no adverse pharmacological effects. However, maca root contains iodine, which can lead to side effects such as thyroid disease. Maca root is also high in glucosinolates and in case of over consumption, combined with low-iodine diet, can cause goiter. It can also cause hives and fatigue to people that are allergic to the constituents of maca tea. Maca Tea is a wonderful tea with many health benefits. It is ideal for incresing your libido and boosting your immune system! Try to avoid over consumption in order not to experience any of its side effects!... maca tea - a libido enhancer

Random Variation / Random Error

The tendency for the estimated magnitude of a parameter (e.g. based upon the average of a sample of observations of a treatment or intervention effect) to deviate randomly from the true magnitude of that parameter. Random variation is independent of the effects of systematic biases. In general, the larger the sample size, the lower the random variation of the estimate of a parameter. As random variation decreases, precision increases.... random variation / random error

Reticulo-endothelial System

This consists of highly specialised cells scattered throughout the body, but found mainly in the SPLEEN, BONE MARROW, LIVER, and LYMPH nodes or glands. Their main function is the ingestion of red blood cells and the conversion of HAEMOGLOBIN to BILIRUBIN. They are also able to ingest bacteria and foreign colloidal particles.... reticulo-endothelial system

Medical Education

This term is used to de?ne the process of learning and knowledge-acquisition in the study of medicine. It also encompasses the expertise required to develop education and training for students and learners in all aspects of medical health care. Studies for undergraduate students, postgraduate students and individual health-care practitioners, from the initial stages to the ongoing development of a career in medicine or associated health ?elds, are also included in medical education. The word ‘pedagogy’ is sometimes applied to this process.

A range of research investigations has developed within medical education. These apply to course monitoring, audit, development and validation, assessment methodologies and the application of educationally appropriate principles at undergraduate and postgraduate levels. Research is undertaken by medical educationalists whose backgrounds include teaching, social sciences and medicine and related health-care specialties, and who will hold a medical or general educational diploma, degree or other appropriate postgraduate quali?cation.

Development and validation for all courses are an important part of continuing accreditation processes. The relatively conservative courses at both undergraduate and postgraduate levels, including diplomas and postgraduate quali?cations awarded by the specialist medical royal colleges (responsible for standards of specialist education) and universities, have undergone a range of reassessment and rede?nition driven by the changing needs of the individual practitioner in the last decade. The stimuli to change aspects of medical training have come from the government through the former Chief Medical O?cer, Sir Kenneth Calman, and the introduction of new approaches to specialist training (the Calman programme), from the GENERAL MEDICAL COUNCIL (GMC) and its document Tomorrow’s Doctors, as well as from the profession itself through the activities of the British Medical Association and the medical royal colleges. The evolving expectations of the public in their perception of the requirements of a doctor, and changes in education of other groups of health professionals, have also led to pressures for changes.

Consequently, many new departments and units devoted to medical education within university medical schools, royal colleges and elsewhere within higher education have been established. These developments have built upon practice developed elsewhere in the world, particularly in North America, Australia and some European countries. Undergraduate education has seen application of new educational methods, including Problem-Based Learning (PBL) in Liverpool, Glasgow and Manchester; clinical and communications skills teaching; early patient contact; and the extensive adoption of Internet (World Wide Web) support and Computer-Aided Learning (CAL). In postgraduate education – driven by European directives and practices, changes in specialist training and the needs of community medicine – new courses have developed around the membership and fellowship examinations for the royal colleges. Examples of these changes driven by medical education expertise include the STEP course for the Royal College of Surgeons of England, and distance-learning courses for diplomas in primary care and rheumatology, as well as examples of good practice as adopted by the Royal College of General Practitioners.

Continuing Professional Development (CPD) and Continuing Medical Education (CME) are also important aspects of medical education now being developed in the United Kingdom, and are evolving to meet the needs of individuals at all stages of their careers.

Bodies closely involved in medical educational developments and their review include the General Medical Council, SCOPME (the Standing Committee on Postgraduate Medical Education), all the medical royal colleges and medical schools, and the British Medical Association through its Board of Medical Education. The National Health Service (NHS) is also involved in education and is a key to facilitation of CPD/CME as the major employer of doctors within the United Kingdom.

Several learned societies embrace medical education at all levels. These include ASME (the Association for the Study of Medical Education), MADEN (the Medical and Dental Education Network) and AMEE (the Association for Medical Education in Europe). Specialist journals are devoted to research reports relating to medical educational developments

(e.g. Academic Medicine, Health Care Education, Medical Education). The more general medical journals (e.g. British Medical Journal, New England Journal of Medicine, The Lancet, Annals of the Royal College of Surgeons) also carry articles on educational matters. Finally, the World Wide Web (WWW) is a valuable source of information relating to courses and course development and other aspects of modern medical education.

The UK government, which controls the number of students entering medical training, has recently increased the quota to take account of increasing demands for trained sta? from the NHS. More than 5,700 students – 3,300 women and 2,400 men – are now entering UK medical schools annually with nearly 28,600 at medical school in any one year, and an attrition rate of about 8–10 per cent. This loss may in part be due to the changes in university-funding arrangements. Students now pay all or part of their tuition fees, and this can result in medical graduates owing several thousand pounds when they qualify at the end of their ?ve-year basic quali?cation course. Doctors wishing to specialise need to do up to ?ve years (sometimes more) of salaried ‘hands-on’ training in house or registrar (intern) posts.

Though it may be a commonly held belief that most students enter medicine for humanitarian reasons rather than for the ?nancial rewards of a successful medical career, in developed nations the prospect of status and rewards is probably one incentive. However, the cost to students of medical education along with the widespread publicity in Britain about an under-resourced, seriously overstretched health service, with sta? working long hours and dealing with a rising number of disgruntled patients, may be affecting recruitment, since the number of applicants for medical school has dropped in the past year or so. Although there is still competition for places, planners need to bear this falling trend in mind.

Another factor to be considered for the future is the nature of the medical curriculum. In Britain and western Europe, the age structure of a probably declining population will become top-heavy with senior citizens. In the ?nancial interests of the countries affected, and in the personal interests of an ageing population, it would seem sensible to raise the pro?le of preventive medicine – traditionally rather a Cinderella subject – in medical education, thus enabling people to live healthier as well as longer lives. While learning about treatments is essential, the increasing specialisation and subspecialisation of medicine in order to provide expensive, high-technology care to a population, many of whom are suffering from preventable illnesses originating in part from self-indulgent lifestyles, seems insupportable economically, unsatisfactory for patients awaiting treatment, and not necessarily professionally ful?lling for health-care sta?. To change the mix of medical education would be a di?cult long-term task but should be worthwhile for providers and recipients of medical care.... medical education

National Institute For Clinical Excellence (nice)

This special health authority in the National Health Service, launched in 1999, prepares formal advice for all managers and health professionals working in the service in England and Wales on the clinical- and cost-e?ectiveness of new and existing technologies. This includes diagnostic tests, medicines and surgical procedures. The institute also gives advice on best practice in the use of existing treatments.

NICE – its Scottish equivalent is the Scottish Health Technology Assessment Centre – has three main functions:

appraisal of new and existing technologies.

development of clinical guidelines.

promotion of clinical audit and con?dential inquiries. Central to its task is public concern about ‘postcode prescribing’ – that is, di?erent availability of health care according to geography.

In 2003 the World Health Organisation appraised NICE. Amongst its recomendations were that there should be greater consistency in the methods used for appraisal and the way in which results and decisions were reported. WHO was concerned about the need for transparency about the con?ict between NICE’s use of manufacturers’ commercial evidence in con?dence, and believed there should be greater de?nition of justi?cation for ‘threshold’ levels for cost-e?ectiveness in the Centre’s judgement of what represents value for money.

In all, WHO was congratulatory – but questions remain about the practical value and imlementation of NICE guidelines.... national institute for clinical excellence (nice)

Nocturnal Enuresis

The involuntary passing of URINE during sleep. It is a condition predominantly of childhood, and usually genetically determined. Sometimes, however, it is a symptom of anxiety in a child, especially if there has been over-rigorous attempts at toilet-training or hostile or unloving behaviour by a parent. It can also be provoked by apparently unimportant changes in a child’s life – for example, moving house. In a small minority of cases it is due to some organic cause such as infection of the genitourinary tract.

The age at which a child achieves full control of bladder function varies considerably. Such control is sometimes achieved in the second year, but much more commonly not until 2–3 years old. Some children do not normally achieve such control until the fourth, or even ?fth, year, so that paediatricians are reluctant to make this diagnosis before a child is aged six.

The approach consists essentially of reassurance and ?rm but kindly and understanding training. In most cases the use of a ‘star chart’ and a buzzer alarm which wakens the child should he or she start passing urine is helpful. Where there are relationship or social problems, these need to be considered in treating the child. The few who have urinary infection or irritable bladders may respond to drug tretament.

Those who do not respond may be helped by DDAVP, an analogue of a pituitary hormone, which reduces the amount of urine produced overnight. It is licensed for use for three months at a time. Some children prefer to reserve it for occasions such as sleeping away from home. The antidepressant imipramine can help some children but has to be used cautiously because of side-effects.

General properties and colour reactions attributed to Ratanjot resemble Alkanet from Alkanna tinctoria Tausch.)... onosma echioides

Oolong Tea Health Benefits, Side Effects And Brewing

Oolong tea, literally meaning “Black Dragon”, is a traditional Chinese beverage which undergoes a unique preparation process resulting in a reddish drink with a slightly sweet delicate flavour. Oolong tea is partially fermented, unlike black tea, which is fully fermented, or green tea, which is unfermented. Oolong Tea Brewing Oolong tea requires a higher brewingtemperature in order to extract the complex aromas of the tea leaves. It is recommended to use spring or filtered water heated at a temperature of approximately 90 degrees Celsius. The steeping process for most Oolong teas should last no longer than five minutes. If this period is extended for too long, it may ruin the delicate aromas and turn your cup of tea unpleasantly bitter. Oolong teas are best served plain, but you can add milk, sugar, honey or lemon according to your taste. Oolong Tea Health Benefits Oolong tea, a hybrid between black and green tea, has numerous health benefits, especially if consumed regularly. Drinking Oolong tea stimulates brain activity and relieves mental and physical stress. Oolong tea has the potential of reducing high blood pressure, lowering blood sugar levels and preventing serious afflictions like obesity, osteoporosis, tooth decay, cancer or heart disease. Oolong tea accelerates the metabolism and promotes weight loss. Another health benefit of Oolong tea is its effectiveness in treating skin problems such as eczema and rashes and combating skin aging. Oolong Tea Side Effects Although drinking Oolong tea is extremely beneficial for the body, it can also lead to unpleasant side effects when consumed in large quantities, therefore moderation is required. These side effects include sleeping difficulties, anxiety or irritability, most of them related to excessive caffeine intake. It is not recommended for pregnant women and people suffering from kidney disorders. Furthermore, oolong tea has been proven to interact with certain medications; therefore, people who undertake treatment are advised to consult a health care provider first. Oolong tea is extremely effective in keeping your energy levels up, due to its caffeine content, and it also increases brain function, helping you maintain active and aware throughout the day.... oolong tea health benefits, side effects and brewing

Patient Empowerment

At a personal level, the engagement of individuals in decisions about their health and about the diagnosis, treatment and after-care of their illness, injuries and other disorders. At a public level, the engagement of all members of the public in the planning, provision and performance of their health-care services. Traditionally, at both personal and public levels, the patient has generally been regarded as naturally subordinate to the politicians and managers who plan and run the health-care system(s), and to health professionals and medical institutions who provide personal health care. The public and patients are increasingly unwilling to accept this traditional model and are asserting themselves, for example through patient help groups, complaints, litigation and local political action with the aim of securing changes in how health care is organised and a much greater say in their own care.... patient empowerment

Plasma Exchange

Also known as plasmapheresis. The removal of the circulating PLASMA from the patient. It is done by removing blood from a patient and returning the red cells with a plasma expander. The plasma exchange is carried out through an in-dwelling CANNULA in the femoral vein, and the red cells and plasma are separated by a hemonetics separator. Usually a sequence of three or four sessions is undertaken, at each of which 2–3 litres of plasma are removed. The lost plasma can either be replaced by human serum albumin (see ALBUMINS) or a plasma expander.

In autoimmune disorders, disease is due to damage wrought by circulating ANTIBODIES or sensitised lymphocytes (see LYMPHOCYTE). If the disease is due to circulating humoral antibodies, removal of these antibodies from the body should theoretically relieve the disorder. This is the principle on which plasma exchange was used in the management of autoimmune diseases due to circulating antibodies. Such disorders include Goodpasture’s syndrome, SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) and MYASTHENIA GRAVIS. One of the problems in the use of plasma exchange in the treatment of such diseases is that the body responds to the removal of an antibody from the circulation by enhanced production of that antibody by the immune system. It is therefore necessary to suppress this homeostatic response with cytotoxic drugs such as AZATHIOPRINE. Nevertheless, remissions can be achieved in autoimmune diseases due to circulating antibodies by the process of plasma exchange.... plasma exchange

Post-mortem Examination

Also called an autopsy (and less commonly, necropsy), this is an examination of a body to discover the causes of death. Such an examination is sometimes required by law. An unnatural death; a death occurring in suspicious circumstances; or a death when a doctor feels unable to complete a certi?cate about the cause – all must be reported to the CORONER (in Scotland, to the procurator ?scal). He or she may order an autopsy to be carried out as part of the inquiry into cause of death. Sometimes doctors may request the permission of relatives to perform a post-mortem so that they may discover something of value for the improvement of medical care. Relatives may refuse consent.

Rheum Emodi

Wall. ex Meissn.

Synonym: R. australe D. Don.

Family: Polygonaceae.

Habitat: Sub-alpine Himalayas, from Kashmir to Sikkim at altitudes of 3,300-5,200 m.; also cultivated in Assam.

English: Indian Rhubarb, Himalayan Rhubarb.

Ayurvedic: Amlaparni, Pitamuuli, Gandhini Revatikaa. Revandachini (roots).

Unani: Revandchini.

Siddha/Tamil: Revalchinikattai, Nattirevaichini.

Action: Purgative, astringent, aperient. Used for constipation and atonic dyspepsia. Not advised for patients suffering from gout, rheumatism, epilepsy. (When given internally, the root imparts a deep tinge to the urine.)

The root gave emodin, emodin- 3-monomethyl ether, chrysophanol, aloe-emodin, rhein. These occur free and as quinone, anthrone or dianthrone glycosides. The astringent principle consists of gallic acid together with small amounts of tannin. The drug also contain cinnamic and rhe- inolic acids, volatile oil, starch and calcium oxalate. Two major glyco- sidic active principles, sennoside A and B, are present along with free an- thraquinones.

At low doses, the tannin exerts astringent effect and relieves diarrhoea; at higher doses anthraquinones stimulate laxative effect and relieve constipation. (Natural Medicines Comprehensive Database, 2007.)

There are three main types of rhubarbs—Chinese, Indian or Himalayan, and Rhapontic.

The Chinese rhubarb consists of the rhizomes and roots of Rheum palma- tum and R. officinale.

The Indian rhubarb consists of dried rhizomes of R. emodi and R. web- bianum; rhizomes and roots of R. moorcroftianum and R. spiciforme are also reported to be mixed with the drug. R. rhaponticum is the Rhapontic rhubarb.

Rheum moorcroftianum Royle (the Himalayas at altitudes of 3,0005,200 m., chiefly in Garhwal and Ku- maon) possesses properties similar to those of R. emodi and the roots are mixed with the latter.

Rheum spiciforme Royle (drier ranges of Kumaon and Sikkim at altitudes of 2,700-4,800 m.) also possesses purgative properties. The rhizomes and roots are mixed up with Himalayan rhubarb.

Rheum webbianum Royle (the western and central Himalayas at altitudes of 3,000-5,000 m.) is the source of Himalayan rhubarb.

Rheum palmatum is esteemed as the best type of (Chinese) rhubarb. Two new stilbene glycosides, 4'-O- methylpiceid and rhapontin, isolated from the roots, exhibited moderate alpha-glucosidase inhibitory activity. Anthraquinone glucoside, pul- matin, isolated from the roots, along with its congeners, chrysophanein and physcionin, showed cytotoxic activity against several types of carcinoma cells. Polysaccharides, isolated from the roots and rhizomes, contained lyx- ose, glucose, galactose, xylose, rham- nose, mannose and ribose.

Sex Education

Information given to children and young adults about sexual relationships. Evidence suggests that young people want more information about the emotional aspects of sexual relationships, and about homosexuality and AIDS/HIV. There is growing concern about sexual risk-taking behaviour among adolescents, many of whom feel that sex education was provided too late for them. Although most parents or guardians provide some guidance by the age of 16, friends, magazines, television and ?lms are a more signi?cant source of information. Schools have been targeted as a place to address and possibly limit risky behaviour because they are geared towards increasing knowledge and improving skills, and have a captive audience of young adults. There are concerns that the conditions in schools may not be ideal: class time is limited; teachers are often not trained in handling sensitive subjects; and considerable controversy surrounds teaching about subjects such as homosexuality.

Sex education in schools is regarded as an e?ective way of reducing teenaged pregnancy, especially when linked with contraceptive services. Several studies have shown that it does not cause an increase in sexual activity and may even delay the onset of sexual relationships and lessen the number of partners. Programmes taught by youth agencies may be even more e?ective than those taught in the classroom – possibly because teaching takes place in small groups of volunteer participants, and the programmes are tailored to their target populations. Despite improvements in sex education, the United Kingdom has the highest incidence of teenaged pregnancies in the European Community.

Sex education, including information about AIDS/HIV and other sexually transmitted infections (STIs), is compulsory in all state-maintained secondary schools in England and Wales. The National Curriculum includes only biological aspects of AIDS/HIV, STIs and human sexual behaviour.

All maintained schools must have a written statement of their policy, which is available to parents. The local education authority, governing body and headteacher should ensure that sex education encourages pupils to have due regard to moral considerations and the value of family life. Sex-education policies and practices are monitored by the O?ce for Standards in Education (OFSTED) and the O?ce of HM Chief Inspector of Schools (OHMCI) as part of school inspections.... sex education

Tea For Edema

Edema is an affection in which the fluid gets trapped between the cell walls and which causes chronic pains and joint weakness. Edema may be caused by a number of things, such as standing too long or having an unhealthy diet, based on salty foods mostly. This is a common problem among pregnant women and, although in folklore there are many remedies, the traditional medicine advices against them. However, alternative medicine practitioners think that you shouldn’t avoid them and, on the contrary, give them a try and, if they don’t work, rush out to the pharmacy. How Tea for Edema Works A Tea for Edema’s main goal is to make all of your cells improve their action and flush away the unnecessary fluid. Of course, this requires ingesting a tea that has diuretic and purgative properties. If you’ve tried a tea to induce sweat or a decoction for constipation, you may want to take it again. The difference is that edema is a much serious condition and therefore needs to be treated more seriously. Efficient Tea for Edema When choosing a Tea for Edema, you must keep in mind two things: it must be safe and it must be one hundred percent safe (edema is a mild affection and you don’t want unnecessary complications). However, if you’re suffering from pulmonary edema (which is a water retention in your lungs), it’s best to ask for medical assistance right away. But if you don’t know which Tea for Edema fits best your condition, here’s a list to choose from: - Garlic Tea – it has a rather unpleasant taste and it doesn’t smell prettier either. You may want to add ginger, mint, lemon or honey to make it more adequate. This Tea for Edema will absorb all unwanted fluids and calm the affected areas. Don’t take more than 2 cups per day in order to avoid digestive tract complications. - Dandelion Tea – has purgative and diuretic properties thanks to which your body will be able to eliminate the water surplus and restore your original health. You can also take it to treat diarrhea, constipation or to induce sweat. - Bilberry Tea – not as popular as the other Teas for Edema, this wonderful decoction is very efficient, but not very safe. It’s true that you can see the results within days, but it’s best to talk to your doctor before making any move. Bilberry Tea is rich in acids and therefore it may cause uterine contractions. - Green Tea – in small dosages, Green tea can treat almost any affection. Be careful, though. It’s not recommended if you are experiencing some menstrual or menopausal symptoms. Green Tea is also a good remedy for asthenia, anemia, sore throats and general weakness. Tea for Edema Side Effects When taken properly, these teas are generally safe. However, exceeding the number of cups recommended per day may cause diarrhea, headaches, vomiting and nausea. If you’ve been taking one of these teas for a while and you’re experiencing some unusual reactions, talk to your doctor immediately. Do not take a treatment based on a tea for Edema if you’re pregnant, breastfeeding, on blood thinners or anticoagulants. The same advice if you’re preparing for a surgery. Once you have your doctor’s ok on the matter, choose a Tea for Edema that fits you best and enjoy its wonderful benefits!... tea for edema

This tea is known for stimulating the brain and the nervous system in a gentler way than coffee. It is also recommended to people who feel tired because of stress.

Tribulus Tea Libido Enhancer

Tribulus Tea is a well known for its aphrodisiac properties and for its ability to enhance the sexual activity, even if Tribulus plant is still considered a pest in many areas of the world. Tribulus is a perennial herb that grows mainly in sunny and warm places, such as Southern Europe, Asia, Africa and Australia, with small green leaves and bright yellow flowers. Its fruits contain a fruit that is round and hard. You can recognize it by its short needles, places on the back side of the leaves and all over the roots. Tribulus Tea Properties The main ingredient of Tribulus Tea is called steroidal sapoins and it can be found mainly in the leaves. However, drinking too much Tribulus Tea may increase your body’s toxicity level and cause great damages to your health. A great amount of steroidal sapoins is hard to be flushed out of your system, so if you’re not sure about taking it and you don’t know how much steroidal sapoins your system can take, talk to a herbalist or to your doctor. Tribulus Tea Benefits Tribulus Tea is a great help when it comes to increasing the libido. However, too much of it may cause you problems. It is also used to treat infertility in men, some erectile disorders and it is said that Tribulus Tea has also anti-tumor properties. Herbalists say that this tea can also increase your muscular mass, lower your blood pressure and your cholesterol. How to make Tribulus Tea Infusion Preparing Tribulus Tea involves following a number of simple steps. Take the fresh or dried herbs (you can use any parts of tribulus plant), put them in a teapot and add boiling water. Leave it for 10 or 15 minutes and drink it hot or cold. Use a teaspoon of herbs for every cup of tea and don’t drink more than 1 or 2 cups per day, for a short time period. Do not turn drinking Tribulus Tea into a daily habit, just take it as long as you need to take advantage of its benefits and then take some time off. This way, your system will be able to flush away any trace of toxicity that this tea could leave. Tribulus Tea Side Effects The main concern when it comes to taking Tribulus Tea is that you shouldn’t drink more than one or two cups per day, for not longer than 7 days. When enhancing your libido, Tribulus Tea increases your hormone level, especially your estrogen and testosterone level. If you are a female, pay attention to hair growth and other male characterics, and if you are a male, make sure you keep an eye on how your glands are behaving. Let’s not forget that Tribulus Tea is a medical treatment and should not be used unsupervised. Before starting a Tribulus Tea Treatment, talk to a specialist. Tribulus Tea Contraindications Do not take Tribulus Tea if you are suffering from one of these conditions: stomach disorders, ulcers, breast and prostate cancers as well as other hormone-dependent problems. The same advice if you are pregnant or breastfeeding: since the active ingredient of this tea enhances your libido by increasing your hormone level, it is best to avoid taking it. If you have already taken it and you’re experiencing vomiting episodes or any other side effect, talk to your doctor as soon as possible! But, if both your health and will are strong, there’s no reason not to take Tribulus Tea. At least give it a try and enjoy the wonderful benefits of this tea!... tribulus tea libido enhancer

Wormwood Tea Benefits And Side Effects

Wormwood Tea has been known for centuries as a great herbal treatment. Greeks used it as a treatment for many diseases, mostly concerning the digestive system problems or nervous system affections. Wormwood is a perennial herb that grows mainly in areas like Europe, Asia and Africa. It has speared-like green leaves, bright yellow flowers and its roots resemble to a rhizome. Also known as artemisia absinthus, wormwood has hallucinogenic and psychoactive properties. Wormwood is widely known as absinthe and it is said that great artists like Van Gogh and Hemingway owe a lot of their creation to wormwood consumption. Wormwood Tea Properties Aside from its hallucinogenic properties, Wormwood Tea turns out to be quite a help when it comes to treating certain health problems. Wormwood Tea is one of the bitterest teas on Earth so only take it combined with honey, ginger or lemon. Wormwood is the main ingredient of absinthe liquor and it’s also used as an important additive for wines, vinegar and vermouth. The active substances of this tea are thujone (absinthol or tenacetone), thujyl alcohol, acids, absinthin, tannins, resin, potash, and starch. Wormwood Tea Benefits Wormwood Tea has been used since ancient times as a hallucinogen in many rituals around the world. Africans believed that Wormwood Tea contained the secret to an absolute freedom of mind and that by taking it you could have reached the peak of human creativity. As crazy as these theories may sound, there are still many cults today that base their entire philosophy on Wormwood Tea consumption. Back to the real world, alternative medicine, by its practitioners, found the real medical benefits of this treatment. Wormwood Tea may come in hand if you are suffering from one of the following conditions: - Indigestion, by inhibiting gastric bacterial and by lowering the microbial risk to infections. - Gastric pains, by decreasing the gastric acidity level. - Loss of appetite, by stimulating intestinal actions and stomach functions. - Worms and other parasites of the digestive system, by flushing them away thanks to an active substance called absinthin. - Immune system deficiencies, by increasing the number of antibodies and by redirecting them to the affected areas. How to make Wormwood Tea Infusion When preparing Wormwood Tea infusion, first you need to make sure that the plants you are about to use are exactly what the label says they are. Only buy Wormwood Tea from trusted providers! Second of all, only use a teaspoon of herbs for every two cups of tea you want to make: the wormwood is a very concentrated herb and you need to be careful when dosing the ingredients. Put the dried herbs in a teapot and add boiling water. Wait for 15 or 20 minutes and drink it hot or cold. However, don’t drink more than a cup of tea per day or you’ll poison your entire nervous system! Wormwood Tea Side Effects When taken according to instructions and under supervised care, Wormwood Tea is safe. However, high dosages may lead to hallucinations, paranoia and other severe conditions of the nervous system. If you’ve been taking Wormwood Tea for a more than three weeks and you’ve noticed some unusual changes in your body reaction, talk to a specialist as soon as possible and don’t try to treat it at home! Wormwood Tea Contraindications Wormwood Tea is not recommended for pregnant or breastfeeding women, children, patients suffering from mental deviations or other serious conditions that imply the use of blood thinners and anti-coagulants. The best thing you can do when it comes to Wormwood Tea consumption is to talk to a herbalist or to your doctor in order to find out more about the ups and downs of this very controversial tea. If you get a specialized approval and you feel very confident about this treatment, give it a try and enjoy the benefits of Wormwood Tea responsibly!... wormwood tea benefits and side effects

Eclectic Medicine

The eclectics were a group of North American physicians who selected from various systems of medicine such principles as they judged to be rational. Their materia medica was based almost entirely on herbal medicine. Part of their knowledge was acquired from the native Indian population and they enjoyed an extraordinary degree of success in the treatment of some of the deeper disturbances of the human race. However, their work was eclipsed by the advance of science and the medical revolution with its brilliant discoveries that have long since been adopted by the orthodox profession. Impressive results were reported in their professional magazine, Ellingwood’s Therapeutist, which continued in publication from the turn of the century until 1920. The recorded experiences of those early pioneers awaken renewed interest today. ... eclectic medicine

Eliminative

A herb to disperse and promote excretion from the body accumulated poisonous substances, metabolites, that may have been ingested as additives in food, inhaled as part of the environment, or acquired as morbid products of inflammation left behind after some acute disease, such as influenza.

Some eliminatives have a biochemical action on cell wastes and toxins, breaking them down preparatory to voiding from the body. Others stimulate organs of elimination to speed them on their journey: liver, kidneys, skin, bowel. This group will therefore include diuretics, hepatics, lymphatics, expectorants, diaphoretics or laxatives according to indications of the case. ... eliminative

Emetic Treatment

As practised by members of the Thomsonian medical fraternity.

An emetic treatment may be administered with good effect when the body is powerless to throw off toxic matter in a healing crisis (acute disease). Uneliminated by-products of carbohydrate and protein metabolism may obstruct the abdominal circulation and congest the tissues. A few days fast followed by emesis has resolved many an acute gastro-intestinal problem.

Requirements: towel, large bowl, strainer, and a bowl of cold water in which a container may be cooled should infusions be too hot.

Before emesis the bowels should be evacuated. A full bowel inhibits the emetic effect and absorbs fluid.

Prepare three one-pint infusions, in separate vessels; cover to prevent escape of essential oils. Infuse 15 minutes.

1. Catnep. 1oz to 1 pint boiling water.

2. Bayberry (or Composition). 1 heaped teaspoon, powder, to 1 pint boiling water.

3. Lobelia. Half an ounce to 1 pint boiling water. Proceed: (a) Drink a cup of Catnep tea (b) follow with a cup of Bayberry (or Composition) tea (c) drink a second cup of Catnep (d) drink a second cup of Bayberry (or Composition). Four cups will be taken at this point, all of which will stimulate mucous surfaces. (e) Follow with a cup of Lobelia tea (a relaxant). (f) Repeat the procedure. Vomiting usually occurs before 8 cups. Repeat the sequence as long as can be borne. About half the intake will be returned. Vomit will be found to be exceedingly viscous and ropy and a healthy sense of well-being can follow its exit from the body. After vomiting three times, or as much as tolerated, discontinue treatment and rest. ... emetic treatment

Such organs may be congested by by-products of disease. Coffee enemas are used for their detoxifying effect.

3 heaped tablespoons of ground coffee (not Instant) to 2 pints (1 litre) water. Bring to boil. Simmer 20 minutes. Strain when warm. Inject one or more pints according to tolerance. “Coffee retention enemas may be given at frequent intervals where well-tolerated, with no side effects.” (Mayo Clinic) (JAMA 245, 591, 1981) ... enema, coffee

Essential Oils

Volatile oils. Out of 250,000 flowering plants only 2,000 yield essential oils. Soluble in alcohol, colourless. Contained in plants, they are responsible for taste, aroma and medicinal action. Organic properties give the flower its scent. May be anti-bacterial, antispasmodic, sedative, expectorant, antiseptic, anti-inflammatory. The smell of a flower roughly conveys the potency of its oil. An example is menthol in the mint family.

Oils used in Phytotherapy: Almond, English Chamomile, Aniseed, Bergamot, Black Pepper, Buchu, Camphor, Cedarwood, Cloves, Coriander, Cypress, Eucalyptus, Geranium, Juniper, Lavender (French), Lavender (English), Lavender (Spanish), Lemon, Marjoram, Orange (sweet), Patchouli, Peppermint, Pine (Scots), Rosemary, Sage, Sandalwood, Thyme, Spearmint, St John’s Wort, Turpentine, Ylang Ylang.

Most oils are obtained by steam distillation. Being highly concentrated, internal use is by a few drops, diluted. About 30-40 are used medicinally; each having its own specific healing properties. Some are convenient as inhalants; a few drops on a tissue for relief of catarrh, colds, etc. Fragrant burners and electronic diffusers are available for vapour-inhalation. Bring to boil 2 pints water; allow to stand 3-4 minutes; sprinkle on the surface 5-10 drops Eucalyptus oil and with towel over head, inhale steam, 5-10 minutes.

Examples: (a) equal parts dilute oils of Thyme and Hypericum (acute middle ear inflammation) 3-4 drops injected into ear 2-3 times daily. (b) 10 drops oil Marjoram in bath water for cramp. Eucalyptus is a useful antibacterial; Cinnamon (anti-inflammatory), Juniper (urinary antiseptic), Orange blossom (anti- depressant), Lavender (sedative).

Essential oils should never be used neat, except as prescribed by a suitably qualified practitioner. While aromatherapists do not prescribe internally, Dr Paul Belaiche, one of France’s leading experts on essential oils, advises oral medication at a maximum daily dosage of 12 drops according to the oil. He advises drops on the tongue, on activated charcoal, in capsule form using a suitable excipient or vegetable oil, or mixed with a little honey. Anal injection has proved successful, (8-10 drops in 10ml vegetable oil) or suppositories made from 200-300mg (8-10 drops) essential oil to 2 grams of base per suppository. Oils should never be allowed to touch the eyes.

Capsules of Garlic oil may be inserted into the rectum for worms or prostate disorder. OR: 10 drops oil mixed with 10ml vegetable oil and injected with the aid of a pipette. Dilute oil of Thyme is used as a massage-rub for chest infections. Oil of Cloves is not only an antiseptic but an analgesic to assuage moderate dental pain. Volatile oils reflexly stimulate the medulla through the olfactory nerve, thus promoting appetite and flow of saliva. All stimulate production of white blood cells and thereby support the immune system.

Oils not used: Basil, Bitter Almonds, Boldo, Calamus, Horseradish, Mugwort, Mustard, Pennyroyal, Rue, Sassafras, Savin, Tansy, Thuja, Wormseed.

Oils not used in pregnancy: Bay, Buchu, Chamomile, Clary Sage, Cinnamon, Clove, Fennel, Hyssop, Juniper, Marjoram, Myrrh, Peppermint, Rose, Rosemary, Sage, Thyme. All other oils – half the normal amount.

Tea: 2-3 drops, selected oil, on teabag makes 3 cups tea.

Inhalant: 10 drops on tissue, or same amount in hot water to inhale steam.

Bath water: add: 10-15 drops.

Compress: 10-15 drops in half a cup (75ml) milk or water. Soak suitable material and apply.

Massage: 6 drops in two teaspoons ‘carrier’ vegetable oil (Almond, Peanut, Olive, etc).

Fragrant oils replace hospital smell.

Flesh-eating Disease

Necrotising fasciitis, in which flesh and muscle are destroyed at a rate of inches an hour. Can spring from a range of streptococcal bacteria of which there are over 80 sub-types.

It seems that this common bacteria, in some unknown way, receives a booster by taking on viral DNA. Lungs, liver and stomach may be attacked, while red blood cells are disrupted and their haemoglobin released. Among other conditions caused by streptococcus is the bright red rash of scarlet fever, sinusitis, meningitis and rheumatic fever. Flesh-eater disease may take just twenty hours to kill a man (“galloping gangrene”).

Symptoms. High temperature – body hot, hands and feet freezing cold. ‘Strep’ sore throat (pharyngitis). Bright red skin rash. Pains in arms and legs as if straining a muscle.

Treatment. The disease is resistant to penicillin. Frequent hot lemon drinks well-laced with honey. Tinctures. Echinacea 2; Goldenseal 1; Myrrh half. Dose: 10-20 drops in dessertspoon water or honey, hourly, acute cases.

Heart – Enlargement

A heart may dilate (enlarge) to compensate for valvular disease. One of two types: (1) Swelling (dilation) of the cavities with thickening of the walls, (hypertrophy of the heart muscle). (2) Dilation of cavities with thinning of the walls.

(1) Arises from the exertions of professional athletes. Extra strain enlarges the heart and calls for compensation. Other causes: high blood pressure and diseased valves.

(2) From anaemia, thyroid disorder, or extra strain demanded by fever. Thin walls always lead to heart weakness, robbing the organ of its maximum power.

Treatment. When compensation is delayed cardiac supportives include Bugleweed (American) to increase force of contractions of the heart and reduce the rate BHP (1983).

Right ventricular enlargement – Stone root.

Left ventricular enlargement – Lily of the Valley.

Both remedies have the advantage of being diuretics, thus aiding elimination of excess fluids.

Heart – Extra Beats

Extra-systoles. An occasional beat or beats may arise prematurely from an abnormal focus in atrium or ventricle. Such is a common occurrence and is little cause for alarm. Simple arrythmia may be the outraged protest of a heart under the influence of alcohol, heavy meals, too much tea or coffee, smoking or excitement. If persistent, examination by a trained practitioner should be sought. For uncomplicated transient extra-systole:–

Alternatives. Teas: Balm, Motherwort, Hawthorn flowers or leaves. Tablets: Hawthorn, Motherwort, Mistletoe, Valerian.

Licencing Of Herbal Remedies – Exemptions From

There are remedies that may be manufactured or assembled by any person carrying on a business or practice provided he or she is occupier of the premises which are closed to exclude the general public. The person (i.e. practitioner) supplies or sells the remedy to a particular person (i.e. patient) having been requested by or on behalf of that person and in that person’s presence to use his/her own judgement as to treatment.

Anyone may administer a herbal product to a human being, except by injection. Under Section 12 of the Medicines Act 1968, any remedy may be sold or supplied which only specifies the plant and the process. The remedy shall be called by no other name. This applies to the process producing the remedy consisting only of drying, crushing and comminuting. It must be sold without any written recommendation for use.

Those who have a manufacturer’s licence, or who notify the Enforcement Authority (the Secretary of State and the Pharmaceutical Society) can sell dried, crushed or comminuted herbs which have also been subjected to certain other limited processes (tablet-making, etc) but not those herbs contained in the Schedule to the Medicines (Retail Sale or Supply of Herbal Remedies) Order 1977 (SI 1977 No.2130).

This Schedule has three parts.

Part 1 contains substances that may only be sold by retail at registered pharmacies under the supervision of a pharmacist.

Part 2 refers to remedies that can be sold only in a registered pharmacy. There is, however, an important exception, as follows.

Part 3 contains a list of considered toxic herbs. A practitioner can prescribe all remedies that a shopkeeper can sell. He may also prescribe and sell remedies on Part 3 of the Schedule which a shopkeeper cannot. Such supply must be in premises closed to the public and subject to a clear and accurate indication of maximum dosage and strength. These remedies are as follows:... licencing of herbal remedies – exemptions from

Liquid Extract (l. E.)

Fluid Extract (F.E.). The most concentrated form in which a herbal medicine can be prepared. Stronger than a tincture. Almost all liquid extracts contain alcohol. Made by a number of methods including cold percolation, evaporation by heat, or under pressure. A popular commercial form of administering herbs as a medicine. Usually taken in water.

Strength: “One part by volume of liquid is equal to 1 part by weight of herb.” Thus, one ounce of fluid is equal to one ounce of crude material. For instance, 1oz Stone root liquid extract would have the same therapeutic potency as 1oz Stone root.

In the making of liquid extracts there is often a loss of valuable volatile constituents which is believed to reduce efficacy of a plant. For this reason tinctures are becoming popular among practitioners. Dosage of L.E.s may vary from 5 to 60 drops according to the plant. For instance, the maximum dosage of Goldenseal is 15, Black Cohosh 30, and Yarrow 60 drops. A general average would appear to be 15-60 drops, though a practitioner would be more specific. The bottle should be shaken vigorously before use to remix any natural sediment.

One millilitre = 15 drops. One teaspoonful = 5ml (5 millilitres) or 75 drops liquid medicine. For liquid medicines, always use medicine glass graduated in millilitres, or standard dropper. ... liquid extract (l. e.)

Emotionally deprived children may be impulsive, crave attention, be unable to cope with frustration, and may have impaired intellectual development.... emotional deprivation

Napier’s Of Edinburgh

Britain’s oldest herbal establishment. Founded by Duncan Scott Napier, 1860, 17, Bristo Place. While run in the light of modern pharmacy it is still complete with its mahogany fittings, antique tincture bottles and bygones of the Victorian herbalist.

In those early days almost all herbs were collected locally and extracts made on the premises for the queues of patients which formed outside until ten o’clock at night. Today crude material comes from abroad for manufacture into their many preparations: Lobelia syrup, Compound Barberry bark, Composition Essence, Skullcap Herb Compound, Heart Tonic, etc. Ginseng, a supposed modern discovery, has been handled by Napier’s for over a century. ... napier’s of edinburgh

Animal Experimentation

The use of animals in research to provide information about animal biology or, by inference, human physiology or behaviour. Animal research has contributed to the development of drugs, such as vaccines, and surgical techniques, such as transplant surgery. However, because of ethical concerns, alternative practices, such as cell cultures, are now used wherever possible.

animals, diseases from See zoonosis. anisometropia Unequal focusing power in the 2 eyes, usually due to a difference in size and/or shape of the eyes, that causes visual discomfort. For example, one eye may be normal and the other affected by myopia (shortsightedness), hypermetropia (longsightedness), or astigmatism (uneven curvature of the cornea). Glasses or contact lenses correct the problem in most cases. ankle joint The hinge joint between the foot and the leg. The talus (uppermost bone in the foot) fits between the 2 bony protuberances formed by the lower ends of the tibia (the shinbone) and the fibula (the outer bone of the lower leg). Strong ligaments on either side of the ankle joint give it support. The ankle allows for up-anddown movement of the foot.

An ankle sprain is one of the most

common injuries.

It is usually caused by twisting the foot over on to its outside edge, causing overstretching and bruising of the ligaments.

Violent twisting of the ankle can cause a combined fracture and dislocation known as Pott’s fracture.... animal experimentation

Barium X-ray Examinations

Procedures used to detect and follow the progress of some gastrointestinal tract disorders. Because X-rays do not pass through it, barium is used to outline organs, such as the stomach, which are not normally visible on an X-ray. In some cases, barium X-rays are an alternative to endoscopy. Barium sulphate mixed with water is passed into the part of the tract requiring examination, and X-rays are taken. X-rays may be singleor double-contrast. Single-contrast barium X-rays use barium sulphate alone. The barium fills the section of the tract and provides an outline image that shows up prominent abnormalities. In double-contrast barium X-rays, the barium forms a thin film over the inner surface of the tract, and the tract is filled with air so that small surface abnormalities can be seen.

Different types of barium X-ray examination are used to investigate different parts of the gastrointestinal tract. Barium swallow involves drinking a barium solution and is used to investigate the oesophagus. A barium meal is carried out to look at the lower oesophagus, stomach, and duodenum. Barium followthrough is used to investigate disorders of the small intestine; X-rays are taken at intervals as the barium reaches the intestine. A barium enema is used to investigate disorders of the large intestine and rectum; barium is introduced though a tube inserted in the rectum. Barium remaining in the intestine may cause constipation. Therefore, it is important to have a high-fibre diet and drink plenty of water after a barium examination, until all the barium has passed through.... barium x-ray examinations

Raised Edge

Shallow of carcinoma ulcer the skin pigment melanin. The risk is reduced by avoiding overexposure to strong sunlight, using sunscreens, and wearing protective clothing and sun hats. Without treatment, the carcinoma gradually invades and destroys surrounding tissues but virtually never spreads to other parts of the body. Treatment is usually with surgery (or in some cases radiotherapy) and is often completely successful. Plastic surgery may also be needed, however, depending on the size and site of the tumour. People who have had a basal cell carcinoma may develop new tumours and should be alert to any changes in their skin. (See also melanoma, malignant; squamous cell carcinoma; sunlight, adverse effects of.)... raised edge

Breast Self-examination

Visual and manual examination of the breasts carried out by a woman to detect lumps

and other changes that might be an indication of early breast cancer. To carry out self-examination, the breasts should be checked in a mirror for any dimpling of the skin or changes in the nipples or breast size and shape. Then, with one arm behind the head, and using small circular movements, the breast should be gently but firmly pressed. The entire breast, armpit area, and nipple should be examined. Regular self-examination helps a woman to become familiar with the appearance and feel of her breasts; any changes should be reported to a doctor without delay.... breast self-examination

Breathing Exercises

Techniques for learning to control the rate and depth of breathing. They aim to teach people to inhale through the nose, while expanding the chest, and then to exhale fully through the mouth, while contracting the abdominal muscles. They are used after chest surgery and for people with chronic obstructive pulmonary disease (see pulmonary disease, chronic obstructive). Breathing exercises can also help people with anxiety disorders and may help to relieve symptoms in some people with asthma.

In yoga, deep rhythmic breathing is used to achieve a state of relaxation. During childbirth, breathing exercises relax the mother and also help to control contractions and reduce pain. (See also physiotherapy.)... breathing exercises

Cervical Erosion

A condition affecting the cervix in which a layer of mucusforming cells more characteristic of those found in the inner lining of the cervix appear on its outside surface. The eroded cervix has a fragile, reddened area on the surface. Usually, there are no symptoms, but some women experience bleeding at unexpected times and may have a vaginal discharge.

Cervical erosion may be present from birth. Other causes include injury to the cervix during labour and long-term use of oral contraceptives. The condition is often detected during a routine cervical smear test.

Only women who have symptoms need treatment.

Abnormal tissue may be destroyed using cauterization, cryosurgery, diathermy, or laser treatment.... cervical erosion

Dental Examination

An examination of the mouth, gums, and teeth by a dentist as a routine check or as part of the assessment a person complaining of a symptom. Routine examinations enable tooth decay and gum disease to be detected and treated at an early stage.

During a routine dental examination, the dentist uses a metal instrument to

probe for dental cavities, chipped teeth, or fillings. Dental X-rays are sometimes carried out to check for problems that may not be visible. Dentists also check how well the upper and lower teeth come together. Regular examinations in children enable the monitoring of the replacement of primary teeth by permanent, or secondary, teeth. Referral for orthodontic treatment may be made. dental extraction See tooth extraction. dental X-ray An image of the teeth and jaws that provides information for detecting, diagnosing, and treating conditions that can threaten oral and general health. There are 3 types of dental X-ray: periapical X-ray, bite-wing X-ray, and panoramic X-ray.

Periapical X-rays are taken using X-ray film held behind the teeth. They give detailed images of whole teeth and the surrounding tissues. They show unerupted or impacted teeth, root fractures, abscesses, cysts, and tumours, and can help diagnose some skeletal diseases. Bite-wing X-rays show the crowns of the teeth and can detect areas of decay and changes in bone due to periodontal disease. Panoramic X-rays show all the teeth and surrounding structures on one large film. They can show unerupted or impacted teeth, cysts, jaw fractures, or tumours. The amount of radiation received from dental X-rays is extremely small. However, dental X-rays should be avoided during pregnancy.... dental examination

Endocrine System

The collection of glands around the body that produce hormones.

These glands include the thyroid gland, pancreas, testes, ovaries, and adrenal glands.

Their hormones are responsible for numerous bodily processes, including growth, metabolism, sexual development and function, and response to stress.

Any increase or decrease in the production of a specific hormone interferes with the process it controls.

To prevent under- or overproduction, hormone secretion from many endocrine glands is regulated by the pituitary gland, which is in turn influenced by the hypothalamus in the brain according to a feedback mechanism.... endocrine system

Doppler Effect

A change in the frequency with which sound waves from a given source reach an observer when the source is in rapid motion with respect to the observer.

Approaching sounds appear higher in pitch (frequency) than sounds that are moving away.

This is because the wavelengths of the sound from an approaching source are progressively foreshortened, whereas the wavelengths from a receding source are stretched.

The Doppler effect is used in ultrasound scanning techniques.

An emitter sends out pulses of ultrasound (inaudible highfrequency sound) of a specific frequency.

When these pulses bounce off a moving object (blood flowing through a blood vessel, for example), the frequency of the echoes is changed from that of the emitted sound.

A sensor detects the frequency changes and converts the data into useful information (about how fast the blood flows, for example).

Doppler ultrasound techniques are also used to monitor fetal heartbeat, to detect air bubbles in dialysis and heart–lung machines, and to measure blood pressure.... doppler effect

Eardrum, Perforated

Rupture or erosion of the eardrum. Perforation of the eardrum can cause brief, intense pain. There may be slight bleeding, a discharge from the ear (see ear, discharge from), and some reduction in hearing.

Most commonly, perforation occurs as a result of the build-up of pus in the middle ear due to acute otitis media. Perforation may also be associated with cholesteatoma. Another cause is injury, for example from insertion of an object into the ear, a loud noise, barotrauma, or a fracture to the base of the skull.

Diagnosis is confirmed by examination of the ear (see ear, examination of).

Hearing tests may also be performed.

Analgesic drugs may relieve any pain and antibiotic drugs may be prescribed to treat or prevent infection.

Most perforations heal quickly.

If the perforation has failed to heal after 6 months, myringoplasty may be needed.... eardrum, perforated

Ear, Examination Of

The ear may be examined to investigate earache, discharge from the ear (see ear, discharge from), hearing loss, a feeling of fullness in the ear, disturbed balance, tinnitus, or swelling of lymph nodes (see glands, swollen) around the ear.

To view the ear canal and eardrum, an otoscope may be used. To obtain images of the middle and inner ears, X-rays, CT scanning, or MRI may be carried out. Hearing and balance can be assessed by means of hearing tests or caloric tests. Electronystagmography assesses balance by watching eye movements when water is inserted into the ear. ear, foreign body in Foreign bodies can easily enter the ear canal. Children often insert objects into their ears, and insects may crawl or fly in. Objects in the ear must be removed by a doctor. This can be done by syringing of the ear or by using fine-toothed forceps. Insects can sometimes be floated out with olive oil or lukewarm water.... ear, examination of

Ectopic Heartbeat

A contraction of the heart muscle that is out of normal timing. An ectopic heartbeat occurs shortly after a normal beat and is followed by a longer than usual interval before the next one.

Ectopic beats can occur in a heart that is otherwise normal and may cause no symptoms. Multiple ectopic beats can cause palpitations. After a myocardial infarction, multiple ectopic beats are a sign of damaged heart muscle. Multiple ectopic beats may lead to ventricular fibrillation, a rapid uncoordinated heartbeat that may be fatal.

Multiple ectopic beats that are causing palpitations, or that occur after a myocardial infarction, are often treated with an antiarrhythmic drug. (See also arrhythmia, cardiac.)... ectopic heartbeat

A tube that is passed into the trachea through the nose or mouth that enables delivery of oxygen during artificial ventilation or of anaesthetic gases (see anaesthesia) during surgery. An inflatable cuff around the lower end of the endotracheal tube prevents secretions or stomach contents from entering the lungs.... endotracheal tube

Enflurane

A liquid mixed with oxygen and inhaled as a vapour to induce and help maintain general anaesthesia (see anaesthesia, general). Rarely, enflurane may cause arrhythmia.... enflurane

Effusion, Joint

The accumulation of fluid in a joint space, causing swelling, limitation of movement, and usually pain and tenderness. A joint is enclosed by a capsule lined with a membrane called the synovium. The synovium normally secretes small amounts of fluid to lubricate the joint, but if it is damaged or inflamed (for example, by arthritis) it produces excessive fluid.

Pain and inflammation may be relieved by analgesic drugs, nonsteroidal anti-inflammatory drugs, and injections of corticosteroid drugs.

Swelling usually reduces with rest, firm bandaging, icepacks, and keeping the affected joint raised.

In some cases, the fluid is drawn out with a needle and syringe.... effusion, joint

Eisenmenger Complex

A condition in which deoxygenated blood flows directly back into the circulation rather than through the lungs, due to an abnormal connection between the left and right sides of the heart and pulmonary hypertension. The resultant hypoxia causes cyanosis, fainting, and breathing difficulty. The disorder most often occurs in people with certain congenital heart defects (see heart disease, congenital), such as ventricular septal defect, that have not been corrected.

The diagnosis is confirmed by cardiac catheterization.

Once Eisenmenger complex has developed, surgical correction of the original defect will not help.

Drug treatment may control symptoms.... eisenmenger complex

Ejaculation, Disorders Of

Conditions in which the normal process or timing of ejaculation is disrupted.

In premature ejaculation, emission of semen occurs before or almost immediately following penetration. Premature ejaculation is the most common sexual problem in men, and is often due to over-stimulation or anxiety about sexual performance. If the problem occurs frequently, sexual counselling and techniques for delaying ejaculation may help (see sex therapy).

Inhibited ejaculation is a rare condition in which erection is normal, or even prolonged, but ejaculation is abnormally delayed or fails to occur. The problem may be psychological in origin, in which case counselling may help, or it may be a complication of a disorder such as diabetes mellitus or alcohol dependence. In some cases, inhibited ejaculation occurs as a side effect of particular drugs, such as some antihypertensive and antidepressant drugs.

In retrograde ejaculation, the valve at the base of the bladder, which normally closes during ejaculation, stays open. As a result, ejaculate is forced back into the bladder. Retrograde ejaculation may occur as a result of a neurological disease, after surgery on the bladder or prostatectomy. There is no treatment, but intercourse with a full bladder can sometimes result in normal ejaculation. (See also azoospermia; psychosexual dysfunction; sexual problems.)... ejaculation, disorders of

Enteritis, Regional

Another name for Crohn’s disease.... enteritis, regional

Epicondylitis

Painful inflammation of an epicondyle, specifically one of the bony prominences of the elbow at the lower end of the humerus. It is due to overuse of forearm muscles, which causes repeated tugging on the tendons attaching to the bone. Epicondylitis affecting the prominence on the outer elbow is called tennis elbow. When the prominence on the inner elbow is affected it is called golfer’s elbow.... epicondylitis

Epididymal Cyst

A harmless swelling, usually painless, that develops in the epididymis.

Small cysts are common in men over 40 and need no treatment.

Rarely, they become tender or enlarge and cause discomfort, in which case surgical removal may be necessary.... epididymal cyst

Epididymo-orchitis

Acute inflammation of a testis along with its associated epididymis. Epididymo-orchitis causes severe pain and swelling at the back of the testis, and, in severe cases, swelling and redness of the scrotum.

The inflammation is caused by infection. Often, there is no obvious source of infection, but sometimes the cause is a bacterial urinary tract infection that has spread via the vas deferens to the epididymis. Treatment is with antibiotic drugs. If there is an underlying urinary tract infection, its cause will be investigated. (See also orchitis.)... epididymo-orchitis

Electrical Injury

Damage to the tissues caused by the passage of an electric current through the body and by its associated heat release. The internal tissues of the body, being moist and salty, are good conductors of electricity. Dry skin provides a high resistance to current flow, but moist skin has a low resistance and thus allows a substantial current to flow into the body. Serious injury or death from domestic voltage levels is thus more likely to occur in the presence of water.

All except the mildest electric shocks may result in unconsciousness. Alternating current (AC) is more dangerous than direct current (DC) because it causes sustained muscle contractions, which may prevent the victim from letting go of the source of the current. A current as small as 0.1 of an amp passing through the heart can cause a fatal arrhythmia. The same current passing through the brainstem may cause the heart to stop beating and breathing to cease. Larger currents, generated by high voltages, may cause charring of tissues, especially where the current enters and exits the body. ... electrical injury

Energy

The capacity to do work or effect a physical change. Nutritionists refer to the fuel content of a food as its energy.

There are many forms of energy, including light, sound, heat, chemical, electrical, and kinetic, and most of them play a role in the body. For instance, the retina converts light energy to electrical nerve impulses, making vision possible. Muscles use chemical energy obtained from food to produce kinetic energy, movement, and heat.

Energy is measured in units called calories and joules.

Because these units are extremely small, more practical units used in dietetics are the kilocalorie (kcal, 1,000 calories), and kilojoule (kJ, 1,000 joules).

Carbohydrates and proteins provide 4 kcal per gramme (g), fats provide 9 kcal per g (see metabolism).

In general, the energy liberated from the breakdown of food is stored as chemical energy in ATP molecules.

The energy in these molecules is then available for processes that consume energy, such as muscle contraction.... energy

Energy Requirements

The amount of energy that is needed by a person for cell metabolism, muscular activity, and growth. This energy is provided by the breakdown of carbohydrates, fats, and proteins supplied by food in the diet and by stored nutrients in the liver, muscles, and adipose tissue.

Energy is needed to maintain the heartbeat, lung function, and constant body temperature. The rate at which these processes use energy is called the basal metabolic rate (BMR). Any form of movement increases energy expenditure above the BMR. A person’s energy requirement increases during periods of growth and during pregnancy and lactation. When more energy is ingested as food than is used, the surplus is stored and there is usually a gain in weight. When less energy is consumed than is spent, weight is usually lost as the stores are used up. (See also nutrition; obesity.)... energy requirements

Epstein–barr Virus

A virus that causes infectious mononucleosis; the virus is also associated with Burkitt’s lymphoma and cancer of the nasopharynx (see nasopharynx, cancer of).... epstein–barr virus

Erection, Disorders Of

Conditions in which the normal process of erection of the penis is disrupted. They include total or partial failure to attain or maintain erection (see impotence), persistent erection in the absence of sexual desire (see priapism), and curving of the penis during erection (see chordee).... erection, disorders of

Ergometer

A machine that measures and records the amount of physical work done and the body’s response to a controlled amount of exercise.

An ergometer makes continuous recordings, both during and after activity, of heart-rate and rhythm (using an ECG), blood pressure, rate of breathing, and volume of oxygen taken in from the air.... ergometer

Erosion, Dental

Loss of enamel from a tooth’s surface due to attack by plaque acids or other chemicals. Erosion of the

outer surfaces of the front teeth is most frequently caused by excessive intake of fruit juices and carbonated drinks. Erosion of the inner surfaces of the molars may be a result of the regurgitation of stomach acid, as occurs in people suffering from acid reflux or bulimia. (See also caries, dental.)... erosion, dental

Erythema Ab Igne

Red, mottled skin that may also be dry and itchy, caused by exposure to strong direct heat, such as when sitting too close to a fire.

The condition is most common in elderly women.

Dryness and itching can often be relieved by an emollient.

The redness fades in time but may not disappear.... erythema ab igne

Erythema Infectiosum

See fifth disease.... erythema infectiosum

Eruption Of Teeth

The process by which developing teeth move upwards through the jawbone and break through the gum to project into the mouth.

Deciduous teeth (milk teeth) usually begin to appear at about 6 months of age. All 20 deciduous teeth have usually erupted by 3 years (see teething).

Permanent teeth (also known as secondary teeth) usually begin to appear at about 6 years of age. The first permanent molars erupt towards the back of the mouth and appear in addition to the deciduous teeth. The eruption of permanent teeth nearer the front of the mouth is preceded by reabsorption of the roots of the deciduous teeth, which become loose and detach. Eventually, permanent teeth replace all the deciduous ones. Wisdom teeth (the backmost, or 3rd, molars) usually erupt between ages 17 and 21, but, in some people, they never appear.... eruption of teeth

Erythema Multiforme

Acute inflammation of the skin, and sometimes of the mucous membranes. The disease can occur as a reaction to certain drugs, or may accompany viral infections such as herpes simplex or bacterial infections such as streptococcal infections. Other possible causes are pregnancy, vaccination, and radiotherapy. Half of all cases occur for no apparent reason.

A symmetrical rash of red, often itchy spots erupts on the limbs and sometimes on the face and the rest of the body. The spots may blister or form raised, pale-centred weals, called target lesions. Those affected may have a fever, sore throat, headache, and/or diarrhoea. In a severe form of erythema multiforme, known as Stevens–Johnson syndrome, the mucous membranes of the mouth, eyes, and genitals are affected and become ulcerated.

Corticosteroid drugs may be given to reduce the inflammation. People with Stevens–Johnson syndrome are also given analgesic drugs and may need intensive care.... erythema multiforme

Escherichia Coli

(E. coli) A bacterium normally found in the intestines which, if it enters the bladder through the urethra, is a common cause of urinary tract infections. Types of E.COLI are often the cause of traveller’s diarrhoea, which is usually a mild illness. However, some strains of the bacterium can cause serious food-borne infections that can result in haemolytic–uraemic syndrome.... escherichia coli

Esmarch’s Bandage

A broad, rubber bandage wrapped around the elevated limb of a patient to force blood out of the blood vessels towards the heart; this creates a blood-free area, enabling surgery to be performed more easily.... esmarch’s bandage

Etretinate can cause liver damage and a rise in blood fats.

The drug should not be taken during pregnancy because of the risk of damage to the fetus.... etretinate

Eucalyptus Oil

A substance distilled from the leaves of eucalyptus trees. Because of its aromatic smell and refreshing taste, it is used as a flavouring, and – applied as a rub, inhaled as vapour, or incorporated in tablets – is also used in cough and cold remedies. There is little evidence that it has any curative properties, although it may relieve symptoms.... eucalyptus oil

Evoked Responses

The tracing of electrical activity in the brain in response to a specific external stimulus. The procedure is similar to that for an EEG.

The technique is used to check the functioning of various sensory systems (such as sight, hearing, or touch). The information obtained can be used to reveal abnormalities caused by inflammation, pressure from a tumour, or other disorders, and to help confirm a diagnosis of multiple sclerosis.... evoked responses

Examination, Physical

The part of a medical consultation in which the doctor looks, feels, and listens to various parts of the patient’s body to assess the patient’s condition or to gather information to help make a diagnosis.

Most examinations include palpation, by which the doctor examines relevant parts of the body for signs such as swelling, tenderness, or enlargement of organs. In some cases, percussion of the chest, or other parts of the body, may be performed by tapping with the fingers and then listening to the sound produced. Auscultation may be used to listen to blood flow through arteries and sounds made by the heart and lungs. The doctor may take the pulse or blood pressure, examine the eyes and ears, and assess the strength and coordination of the muscles.... examination, physical

Exercise Ecg

The use of electrocardiography (see ECG) to assess the function of the heart when it is put under the stress of exercise.

Exercise is usually carried out when coronary artery disease is suspected.

It involves raising the heart rate by exercising, usually on a treadmill with an adjustable gradient or an exercise bicycle, and recording the heart’s electrical activity for analysis.... exercise ecg

Exfoliative Dermatitis

A skin disorder characterized by inflammation, redness, and scaling of the skin over most of the body. Exfoliative dermatitis may be the result of an allergic response to a drug or may be due to worsening of a skin condition such as psoriasis or eczema. The condition sometimes occurs in lymphoma and leukaemia.

There is a widespread rash with severe flaking of the skin, which results in increased loss of water and protein from the surface of the body.

Protein loss may cause oedema and muscle wasting.

Further possible complications include heart failure and infection.

The treatment and outlook depend on the cause.... exfoliative dermatitis

Exploratory Surgery

Expressing Milk

A technique used by breast-feeding women for removing milk from the breasts.

It may be needed if the woman’s breasts are overfull (see engorgement).

A woman may want to express milk so that it can be given to the baby in her absence, or so that an infant unable to feed at the breast, due to prematurity, for example, can benefit from breast milk.

Milk can be expressed by hand or with a breast pump.... expressing milk

Exstrophy Of The Bladder

A rare birth defect in which the bladder is turned inside out and is open to the outside of the body through a space in the lower abdominal wall.

Usually, there are also other defects, such as epispadias in males and failure of the pubic bones to join at the front.

Surgical treatment involves reconstructing the bladder and closing the abdominal wall.

If the bladder is very small, it is removed and the urine diverted (see urinary diversion).... exstrophy of the bladder

Extraction, Dental

Removal of teeth by a dentist. Extraction may be performed when a tooth is severely decayed or too badly broken to be repaired, or when an abscess (see abscess, dental) has formed. Teeth may also be removed if there is crowding or malocclusion, if the teeth are loose due to gum disease, or if they are preventing another tooth from erupting (see eruption of teeth).

For most extractions, local anaesthesia is used (see anaesthesia, dental). Teeth are usually extracted with dental forceps, which grasp the root of the tooth. In difficult extractions, some gum and bone may also need to be removed from around the tooth.... extraction, dental

Eyelashes, Disorders Of

The eyelashes are arranged in two rows at the front edge of the lid and normally curve outwards.

Growth in an abnormal direction may be due to injury to the lid or, more commonly, to infection.

Severe blepharitis may destroy the roots of the lashes.

Trachoma, an infection in which the lid is distorted by scarring, may lead to trichiasis.

With age, the lashes become finer and fewer.... eyelashes, disorders of

Extradural Haemorrhage

Bleeding into the space between the inner surface of the skull and the external surface of the dura mater, the outer layer of the meninges. Extradural haemorrhage usually results from a blow to the side of the head that fractures the skull and ruptures an artery running over the surface of the dura mater. A haematoma (collection of clotted blood) forms and enlarges, causing an increase in pressure inside the skull and resulting in symptoms several hours or even days after the injury. Symptoms may include headache, drowsiness, vomiting, paralysis affecting one side of the body, and seizures. Untreated, extradural haemorrhage may be life-threatening.

CT scanning or MRI confirms the diagnosis.

Surgical treatment consists of craniotomy, draining the blood clot, and clipping the ruptured blood vessel.... extradural haemorrhage

Eye, Examination Of

An inspection of the structures of the eyes, either as part of a vision test or to make a diagnosis when an eye disorder is suspected.

An eye examination usually begins with inspection of the external appearance of the eyes, lids, and surrounding skin. A check of eye movements is usually performed and the examiner looks for squint. A check of the visual acuity in each eye using a Snellen chart follows. Refraction testing (using lenses of different strengths) may be performed to determine what glasses or contact lenses, if any, may be needed. A test of the visual fields may be performed, especially in suspected cases of glaucoma or neurological conditions. Colour vision may be checked because loss of colour perception is an indication of certain disorders of the retina or optic nerve. To check for abrasions or ulcers, the conjunctiva and cornea may be stained with fluorescein. Applanation tonometry is an essential test for glaucoma.

The ophthalmoscope is an instrument used to examine the inside of the eye, particularly the retina. The slit-lamp microscope, with its illumination and lens magnification, allows examination of the conjunctiva, cornea, front chamber of the eye, iris, and lens. For a full view of the lens and the structures behind it, the pupil must be widely dilated with eye-drops.... eye, examination of

Falls In The Elderly

The tendency to fall increases steadily with age. Reflex actions become slower, and an elderly person who trips is frequently too slow to prevent a fall. Various medical conditions common in the elderly, including poor sight, walking disorders, cardiac arrhythmias, hypotension, and Parkinson’s disease, increase the risk of falls, as does taking sleeping drugs or tranquillizer drugs.

Broken bones (see fracture) are a common complication of falls, especially in women. Not only do women have more falls, they are also more likely to suffer fractures because their bone strength may be reduced due to osteoporosis. A fall, or the fear of falling, can also have adverse psychological effects on an elderly person, who may become reluctant to leave the home.

Falls may be prevented by taking common-sense measures such as ensuring that handrails are secure, good lighting is available, suitable footwear is worn, and floor coverings and wiring are safe.... falls in the elderly

Femoral Epiphysis, Slipped

Displacement of the upper epiphysis (growing end) of the femur (thigh bone). Such displacement is rare; it usually affects children between 11 and 13, and occurs more often in boys and obese children. The condition may also run in families. During normal growth, the epiphysis is separated from the shaft of the bone by a plate of cartilage. This is an area of relative weakness, so that a fall or other injury can cause the epiphysis to slip out of position. A limp develops, and pain is felt in the knee or groin. The leg tends to turn outwards and hip movements are restricted.

Surgery is needed to fix the epiphysis into its correct position and is usually completely successful.

In some cases, the other hip may also need to be stabilized.... femoral epiphysis, slipped

It may also be caused by vitamin deficiency, injury, or infection of a primary tooth that interferes with enamel maturation.... hypoplasia, enamel

Middle-ear Effusion, Persistent

See glue ear.... middle-ear effusion, persistent

Gastric Erosion

A break in the surface layer of the membrane lining the stomach. A break deeper than this layer is called a gastric ulcer (see peptic ulcer).Gastric erosions occur in some cases of gastritis.

Many erosions result from ingestion of alcohol, iron tablets, or aspirin.

The physical stress of serious illness, such as kidney failure, or of burns may bring on an erosion.

Often there are no symptoms, but erosions may bleed, causing vomiting of blood or blood in the faeces.

Persistent loss of blood may lead to anaemia.

Gastric erosions are diagnosed by gastroscopy.

They usually heal in a few days when they are treated with antacid drugs and ulcer-healing drugs.... gastric erosion

Metabolism, Inborn Errors Of

Inherited defects of body chemistry. Inborn errors of metabolism are caused by single gene defects, which lead to abnormal functioning of an enzyme.

Some of these gene defects are harmless, but others are severe enough to result in death or physical or mental handicap. Examples include Tay–Sachs disease, phenylketonuria, Hurler’s syndrome, and Lesch–Nyhan syndrome. Collectively, inborn errors of metabolism affect around 1 child in 5,000.

Symptoms are usually present at or soon after birth. They may include unexplained illness or failure to thrive, developmental delay, floppiness, persistent vomiting, or seizures.

Routine tests are performed on newborn babies for some genetic disorders, such as phenylketonuria.

Treatment is not needed for some inborn errors of metabolism. For others, avoidance of a specific environmental factor may be sufficient. In some cases, the missing enzyme or the protein that it produces can be manufactured using genetic engineering techniques, or a vitamin supplement can help compensate for the defective enzyme. If the enzyme is made in blood cells, a bone marrow transplant may provide a cure.

People with a child or a close relative who is affected may benefit from genetic counselling before planning a pregnancy.... metabolism, inborn errors of

Necrolysis, Toxic Epidermal

A severe, blistering rash in which the surface layers of the skin peel off, exposing large areas of red raw skin over the body. The condition carries a risk of widespread infection and loss of body fluid and salts.

The most common cause of toxic epidermal necrolysis is an adverse reaction to a drug, particularly a barbiturate, sulphonamide, or penicillin. The condition usually clears up when the drug is discontinued. Intravenous fluid replacement is sometimes necessary.... necrolysis, toxic epidermal

Needle Exchange

Nuclear Energy

The energy released as a result of changes in the nuclei of atoms. It is also known as atomic energy and is principally released in the form of heat, light, and ionizing radiation, such as gamma rays.

Nuclear energy is released in certain natural processes, including the spontaneous decay of radioactive substances such as uranium ores, and the nuclear reactions that power the sun. It is also what powers nuclear reactors.... nuclear energy

Otoacoustic Emission

An echo emitted by the inner ear in response to sound.

The emission is produced only by a normally functioning ear and is recorded in a test to detect impaired hearing.... otoacoustic emission

Pelvic Examination

Examination of a woman’s external and internal genitalia.

After examination of the external genitalia, a speculum is inserted into the vagina to allow a clear view of the cervix.

A cervical smear test may be performed.

The doctor inserts 2 fingers into the vagina and, with the other hand, feels the abdomen to evaluate the position and size of the uterus and the ovaries and to detect any tenderness or swelling.... pelvic examination

Pleural Effusion

An accumulation of fluid between the layers of the pleura, making breathing difficult. Pleural effusion may be caused by pneumonia, tuberculosis, heart failure, cancer, pulmonary embolism, or mesothelioma.

Diagnosis is confirmed by chest X-ray.

Some fluid may be removed with a needle and syringe and examined to find the cause.

A biopsy of the pleura may also be needed.

The underlying cause is treated and fluid may be drained off to relieve breathing problems.... pleural effusion

Postmortem Examination

An alternative term for an autopsy.... postmortem examination

Ringing In The Ears

See tinnitus.... ringing in the ears

Salivation, Excessive

The production of too much saliva. Excess salivation sometimes occurs during pregnancy. Other causes include mouth problems such as irritation of the mouth lining, gingivitis, or mouth ulcers; digestive tract disorders such as peptic ulcers and oesophagitis; and nervous system disorders such as Parkinson’s disease. In some cases, it may be reduced by anticholinergic drugs.... salivation, excessive

Pelvic Floor Exercises

A programme of exercises to strengthen the muscles and tighten the ligaments at the base of the abdomen, which form the pelvic floor.

These muscles and ligaments support the uterus, vagina, bladder, urethra, and rectum. Performing the exercises may help to prevent prolapse of the uterus (see uterus, prolapse of) and urinary stress incontinence (see incontinence, urinary). They may also help women who find achieving orgasm difficult.

The pelvic floor muscles are those that tighten when urine flow is stopped midstream. The exercises involve stopping and starting urine flow several times by contracting and relaxing the muscles. Ideally, they should be performed for 5 minutes every hour throughout the day. They can be done standing, sitting, or lying down, by imagining that urine is being passed, contracting and holding the muscles for 10 seconds, and then slowly releasing them, repeating 5–10 times as often as possible.... pelvic floor exercises

Prostate, Enlarged

An increase in the size of the inner zone of the prostate gland, also known as benign prostatic hypertrophy. It is most common in men over 50. The cause is unknown. The enlarging prostate compresses and distorts the urethra, impeding the flow of urine. Eventually the bladder is unable to expel all the urine (see urine retention) and becomes distended, causing abdominal swelling. There may also be incontinence and frequency of urination (see urination, frequent).

Prostate enlargement is detected by a rectal examination.

Tests may include a blood test, ultrasound scanning, urography, and a recording of the strength of urine flow.

Mild cases do not require treatment, but more severe ones usually require prostatectomy.

Alternatively, drug treatment with alpha-blocker drugs or androgen drugs may be given.... prostate, enlarged

Shock, Electric

The sensation caused by an electric current passing through the body, and its effects.

A current of sufficient size and duration can cause loss of consciousness, cardiac arrest, respiratory arrest, burns, and tissue damage.

(See also electrical injury.)... shock, electric

Slipped Femoral Epiphysis

See femoral epiphysis, slipped.... slipped femoral epiphysis

Sunlight, Adverse Effects Of

Problems resulting from overexposure to sunlight. Fair-skinned people are more susceptible. Short-term overexposure causes sunburn and, in intense heat, can result in heat exhaustion or heatstroke. Repeated overexposure over a long period can cause premature aging of the skin and solar keratoses. It increases the risk of skin cancer. Protection of the skin with sunscreens helps to prevent sun damage. Photosensitivity is an abnormal sensitivity to sunlight, resulting in a rash.

Exposure to sunlight can affect the eyes, causing irritation of the conjunctiva, actinic keratopathy, or pterygium.

Good sunglasses help to prevent eye problems.... sunlight, adverse effects of

Testis, Ectopic

A testis that is absent from the scrotum because it has descended into an abnormal position, usually in the groin or at the base of the penis. The condition is most often discovered soon after birth during a routine physical examination. It is treated by orchidopexy. (See also testis, undescended.) ... testis, ectopic

Thirst, Excessive

A strong and persistent need to drink, most commonly due to dehydration. Other causes include untreated diabetes mellitus and diabetes insipidus, kidney failure, treatment with phenothiazine drugs, and severe blood loss. Abnormal thirst may also be due to a psychological condition known as psychogenic polydipsia.... thirst, excessive

Urination, Excessive

The production of more than 2.5 litres of urine per day. The medical term is polyuria.

Causes include psychiatric problems, which may cause a person to drink compulsively; diabetes mellitus; disorders of the kidney known as salt-losing states; and central diabetes insipidus. Any person who passes large quantities of urine should consult a doctor.... urination, excessive

Ventricular Ectopic Beat

A type of cardiac arrhythmia in which abnormal heartbeats are initiated from electrical impulses in the ventricles of the heart. In a normal heart, beats are initiated by the sinoatrial node in the right atrium.

Ventricular ectopic beats may be detected on an ECG.

If there are frequent abnormal beats that cause symptoms, or beats that arise from more than 1 site in the ventricles, treatment with an antiarrhythmic drug may be required.... ventricular ectopic beat

Zollinger–ellison Syndrome

A rare condition characterized by severe and recurrent peptic ulcers in the stomach, duodenum, and jejunum (the 2nd part of the small intestine). Zollinger–Ellison syndrome is caused by 1 or more tumours in the pancreas that secrete the hormone gastrin. Gastrin stimulates production of large quantities of acid by the stomach, which leads to ulceration. The high levels of acid in the digestive tract often also cause diarrhoea.

The tumours are cancerous, but of a slow-growing type.

If possible, they are removed surgically.

Proton pump inhibitor drugs are given to treat the ulcers.... zollinger–ellison syndrome

Accident And Emergency Medicine

Vacuum Extraction

An obstetric procedure to facilitate the delivery of a baby. It may be used if the second stage of labour (see childbirth) is prolonged, if the mother becomes exhausted, or if the baby shows signs of fetal distress. Vacuum suction techniques are also used to perform early abortions.

The vacuum extraction instrument consists of a suction cup connected to a vacuum bottle. The suction cup is placed on the baby’s head in the birth canal, and the vacuum machine sucks the baby’s scalp into the cup. The obstetrician draws the baby out of the mother’s vagina by gently pulling on the cup with each uterine contraction.

The baby is born with a swelling on the scalp, but this disappears after a few days, usually without treatment.... vacuum extraction

Acid-etch Technique

a technique for creating a mechanical bond between resin-based materials and the enamel of teeth; it is used to retain and seal the margins of composite fillings, to retain brackets of fixed orthodontic appliances, and to retain resin-based *fissure sealants and adhesive bridges. Phosphoric acid is used to create a porous surface into which a bonding agent can flow.... acid-etch technique

Acute Generalized Exanthematous Pustulosis

(toxic pustuloderma) a reaction to a medication, resulting in the appearance of fine sterile *pustules on inflamed skin; the pustules may easily be overlooked. Common causes include penicillins, and pustular psoriasis must be excluded from the diagnosis.... acute generalized exanthematous pustulosis

Aerobic Exercises

see exercise.... aerobic exercises

Amniotic Fluid Embolism

a condition in which amniotic fluid enters the maternal circulation causing a complex cascade similar to that seen in anaphylactic and septic *shock. It is a rare event (1 in 50,000–100,000 deliveries), with a 60–80% maternal mortality. The sudden onset of cardiopulmonary collapse, together with coma or seizures, in labour or shortly after delivery, should prompt the diagnosis. Most of the women who survive have permanent neurological damage.... amniotic fluid embolism

(AVNRT) *re-entry tachycardia arising from the presence of an abnormal electrical connection between atria and ventricles situated within the *atrioventricular node.... atrioventricular nodal re-entry tachycardia

Automated External Defibrillator

(AED) a type of external *defibrillator that can analyse the heart rhythm it detects and advise via voice prompts on therapy to be given according to the latest guidelines. In cases of ventricular fibrillation, some defibrillators will make decisions on delivering electric shocks and do so after issuing appropriate warnings to the attending health-care professionals.... automated external defibrillator

Balloon Eustachian Tuboplasty

a surgical procedure used to treat dysfunction of the *Eustachian tube. A small balloon is inserted from the *nasopharynx into the Eustachian tube in a deflated state under endoscopic control. It is then inflated to widen the Eustachian tube before being deflated and removed.... balloon eustachian tuboplasty

Barium Enema

a radiological technique used to diagnose conditions of the large bowel using the combination of X-ray imaging and radiopaque contrast (barium sulphate). Prior bowel cleansing is usually required with a colonic cleansing preparation. A large-bore tube with a balloon is inserted into the rectum and through this the barium is delivered to the caecum. The balloon is inflated in the rectum to prevent leakage of barium outside. In *double contrast studies, air is passed through the catheter to distend the colon. A series of radiographs are taken after barium has coated the colon, and the patient may be asked to change position to ensure that the whole bowel is delineated. Barium enema is used to identify colonic polyps, colorectal cancer, and diverticular disease. However, its role has been largely taken over by *colonoscopy which enables additional mucosal sampling and therapeutic intervention.... barium enema

In the UK, clinical *ethics committees are increasingly common in the NHS.... clinical ethics

Confidential Enquiries

special enquiries that seek to improve health and health care by collecting evidence on aspects of care and disseminating recommendations based on these findings. MBRRACE-UK (Mothers and Babies; Reducing Risks through Audits and Confidential Enquiries in the UK) investigates maternal deaths, stillbirths, late fetal losses and terminations, and neonatal deaths (see infant mortality rate; maternal death; maternal mortality rate; perinatal mortality rate). It replaced the Centre for Maternal and Child Enquiries (CMACE), which carried out this work until 2012.

Doctrine Of Double Effect

the principle that, where it is foreseen that a single action will have both a good and a bad outcome, a person may perform such an action provided that (a) he or she intends only the positive outcome, (b) the bad outcome is not disproportionate to the good, and (c) the good outcome is not a direct consequence of the bad. The classic example occurs where a terminally ill patient requires high doses of opiates for pain relief that may also depress respiratory function and hasten his or her death. In such a case the law holds that the doctor may supply the necessary dosage without this being considered tantamount to *euthanasia, even though the outcome will be the same, i.e. the morality of the action does not lie in its consequences (see consequentialism).... doctrine of double effect

Ebola Virus

a virus responsible for an acute infection in humans with features similar to those of *Marburg disease. Transmission is by contact with infected blood and other body fluids and the incubation period is 2–21 days (7 days on average). The mortality rate is 53–88%, but intensive treatment (including rehydration) in the early stages of the disease can halt its rapid and usually irreversible progression to haemorrhaging of internal organs. Until recently, sporadic but short-lived outbreaks have occurred in Africa since 1976, when the virus was first identified during an outbreak in the region of the Ebola river, in Zaïre (now Democratic Republic of Congo). A major epidemic of the disease broke out in West Africa at the end of 2013 and lasted until May 2016: over 11,000 people died. An unknown species of animal – possibly a fruit bat – is assumed to act as a reservoir for the virus between outbreaks of the disease in humans.... ebola virus

Effectiveness And Efficiency

n. measures that are used in health economics and ethics to assess treatments of all kinds. A treatment that works or achieves its object is effective, but may do so at great cost. If it is also efficient, it achieves its aim equally but at lower cost (or consumes less resources) when compared with other treatments. Such an assessment may be part of an *intervention study. Even apparently effective and efficient treatments may work for patients only by depriving others of similar care (opportunity costs), so a moral evaluation must take into account the overall aims and purposes of health care in general.... effectiveness and efficiency

Ehlers–danlos Syndrome

any one of a rare group of inherited (autosomal *dominant or autosomal *recessive) disorders of the connective tissue involving abnormal or deficient *collagen, the protein that gives the body tissues strength. There are several types of differing severity. The skin of affected individuals is very elastic but also very fragile: it bruises easily and scars poorly, the scars often being paper-thin. The joints of those affected tend to be very mobile (double-jointed) and dislocate easily. In some types the uterus or bowel can rupture or the valves in the heart can be weaker than normal. [E. L.

Elastase

n. an enzyme that breaks down various proteins including elastin, which has a role in the connective tissue matrix. Pancreatic elastase, secreted by the pancreas, is not degraded in the small or large intestine; therefore its concentration in the stools expresses the functioning of the pancreas, which is the basis for the faecal pancreatic elastase test. In patients who have suspected pancreatic insufficiency, faecal pancreatic elastase is suppressed or absent. Patients at risk include those with chronic pancreatitis, cystic fibrosis, pancreatic cancer, or previous pancreatic surgery.... elastase

It has been found useful in demonstrating abnormalities of muscle, liver, and breast tissue.... elastography

Eisenmenger Reaction

(Eisenmenger syndrome) a condition in which *pulmonary hypertension is associated with a *septal defect, so that blood flows from the right to the left side of the heart or from the pulmonary artery to the aorta. This allows blue blood, poor in oxygen, to bypass the lungs and enter the general circulation. This reduces the oxygen content of the arterial blood in the aorta and its branches, resulting in a patient with a dusky blue appearance (*cyanosis) and an increased number of red blood cells (*polycythaemia). There is no curative treatment at this stage, but the patient may be helped by the control of heart failure and polycythaemia. The condition may be prevented by appropriate treatment of the septal defect in early childhood before irreversible pulmonary hypertension develops. [V. Eisenmenger (1864–1932), German physician]... eisenmenger reaction

Users are asked to talk about certain key moments of contact with the service (e.g. arrival on the ward, waking after an operation) and to characterize their experience using a selection of emotional words. The goal is to help staff to understand how users felt at these moments and thereby to develop more compassionate, holistic, and insightful care.... emotional touchpoints

Empowerment

n. giving or returning power to someone. Being ill is usually experienced as losing the ability to act as one wishes, and full recovery may only be achieved when the individual feels able to make their own decisions. This may be a problem where professionals insist on deciding for patients with certain conditions (e.g. mental illness). Empowerment involves action to redress the lack or *loss, for instance by offering explanation in a language, style, and level that is appropriate. See also autonomy; feminist ethics; paternalism.... empowerment

ECMO is only available in selected high-technology centres.... extracorporeal membrane oxygenation

Extraction

n. 1. the surgical removal of a part of the body. Extraction of teeth is usually achieved by applying *elevators and extraction *forceps to the crown or root of the tooth to dislocate it from its socket.

Extraordinary Means

life-prolonging treatments that are not regarded as beneficial (i.e. they do nothing to promote recovery or relieve suffering) and that may even be burdensome to the patient. It has been argued that there is no moral obligation to prolong life and/or to impose greater suffering by extraordinary means. ‘Extraordinary’ does not mean unusual: treatments that are considered routine may be classed as extraordinary when they are no longer clinically effective or are considered *futile. Another way to describe the appropriateness of such interventions is to talk of ‘proportionate’ and ‘disproportionate’ means. See artificial nutrition and hydration.... extraordinary means

Extrapleural

adj. relating to the tissues of the chest wall outside the parietal *pleura.... extrapleural

People high in extroversion (extroverts), as measured by questionnaires and tests, are gregarious and outgoing, prefer to change activities frequently, and are not susceptible to permanent *conditioning. Extroversion was first described by Carl Jung as a tendency to action rather than thought, to scientific rather than philosophical interests, and to emotional rather than intellectual reactions. Eysenck used it as one of the main personality traits in his widely used personality questionnaire. Compare introversion. 2. a turning inside out of a hollow organ, such as the uterus (which sometimes occurs after childbirth).... extroversion

Fuchs’ Endothelial Dystrophy

a hereditary condition in which the corneal endothelium loses its functional ability, usually with age. It may result in thickening and swelling of the cornea (*bullous keratopathy) and thus affect vision. Cornea guttata, small whitish deposits of hyalin, are seen on the inner surface of the cornea and signify a reduced number of endothelial cells. A corneal transplantation (see keratoplasty) may become necessary in certain cases. [E. Fuchs (1851–1913), German ophthalmologist]... fuchs’ endothelial dystrophy

Human Fertilisation And Embryology Acts

Acts of the UK parliament in 1990 and 2008, establishing and amending principles for the legal supervision, by the Human Fertilisation and Embryology Authority, of the creation, use, and storage of human embryos outside the body and of their use in treatment and research. The 2008 amendments included a ban on sex selection for social reasons, recognition of same-sex couples as potential legal parents, and regulations related to developing areas of research using embryos. The 1990 Act had also reduced the legal time limit for most abortions from 28 weeks gestation (as in the 1967 Abortion Act) to 24 weeks. Interpretation and regulation of principles and practice in this rapidly developing area of research and practice continue and are often controversial.... human fertilisation and embryology acts

Kantian Ethics

approaches to moral questions based on the thought of the German philosopher Immanuel Kant (1724–1804). These seek to discover what is morally right by asking what basic rules all rational people (see autonomy) could adopt for themselves and then act on as an *imperative matter of *duty, regardless of their personal desires or of the possible consequences (see deontology; consequentialism). The Kantian tradition has been influential in medical ethics, especially in its insistence that every human life must be treated as an end in itself and not simply as a means.... kantian ethics

Kegel Exercises

(pelvic-floor muscle training, pelvic-floor exelrcises) active rehabilitation of the pelvic-floor muscles by conscious contractions, which leads to a cure in 50–80% of patients with stress incontinence. [A. H. Kegel (20th century), US gynaecologist]... kegel exercises

Medical Emergency Team

(MET) a team, usually consisting of a group of physicians, anaesthetists, and senior nurses, that can be summoned urgently to attend to patients with deteriorating medical conditions. The aim is to prevent further deterioration and to decide if enhanced levels of care are appropriate (e.g. on the high-dependency or intensive care units). The team will also assume the role of the *cardiac-arrest team.... medical emergency team

Mental State Examination

(MSE) a full psychiatric examination of signs and symptoms, which takes place during a psychiatric interview and should apply only to signs and symptoms elicited at that time; it should not take into account historical information.

Middle East Respiratory Syndrome

(MERS) a viral respiratory infection that was first identified in 2012. Humans seem to be infected most easily by contact with dromedary camels (hence the informal name camel flu), although human-to-human infection also occurs. Symptoms include fever, cough, and shortness of breath. Although the syndrome is often mild, death occurs in about a third of diagnosed cases. Most reported cases have been in the Arabian Peninsula, although there was a major outbreak in South Korea in 2015. At present there is no vaccine or treatment.... middle east respiratory syndrome

Medical Ethics

the standards of conduct required of medical professionals and also the academic study of ethical issues arising from the practice of medicine. From the *Hippocratic oath onwards, standards are designed to reassure that professionals subscribing to them will act in the *best interests of, and will avoid harming, their patients. Today they lay greater emphasis on patient *autonomy, while the contemporary study of medical ethics is concerned with a great variety of complex societal and social issues related to medical practice and research. Medical ethics is now taught in all medical schools in the UK as an essential part of a professional training, and the wider field of *bioethics is becoming a recognized academic specialty. See also clinical ethics; feminist ethics; public health ethics; publication ethics; virtue ethics.

National Statistics Socio-economic Classification

(NS-SEC) an occupational classification of the national population that was developed to replace older systems based on social classes and socio-economic groups. The groupings are intended to stratify the population according to different forms of employment: households are classified according to the occupation of the household reference person (the person renting, owning, or otherwise responsible for accommodation). The NS-SEC is used for official surveys and statistics, including the *census. The analytic version of the classification has eight classes and is the version used for most analyses.... national statistics socio-economic classification

Necrotizing Enterocolitis

(NEC) a serious disease affecting the bowel during the first three weeks of life; it is much more common in preterm babies. The abdomen distends and blood and mucus appear in the stools; the bowel may perforate. Treatment is to rest the bowel and administer antibiotics.

Non-epileptic Seizure

n. an event with symptoms that mimic an epileptic seizure but that does not involve abnormal discharges of cortical neurons that would be captured on an EEG. It can be caused by both physiological and psychological conditions. Physiological causes include syncopes, cataplexy, migraine, narcolepsy, parasomnias, and tics. Psychological non-epileptic seizures, also known as psychogenic non-epileptic seizures, can arise from acute distress or anxiety or in the context of a *somatic symptom. People who suffer from epilepsy may have non-epileptic seizures as well. The main visible difference between a non-epileptic seizure and an epileptic seizure is that the former commonly lasts longer than two minutes and can last up to 30 minutes. Also there is occasional pelvic thrusting, the patient’s eyes and mouth are typically closed, and side-to-side head movements are more common than in epileptic seizures. Crying or talking during the attack is possible. There is no *postictal phase. Other names for non-epileptic seizures include pseudo seizures, functional seizures, and conversion seizures.... non-epileptic seizure

Objective Structured Clinical Examination

(OSCE) a type of examination used increasingly in the health sciences (medicine, dentistry, nursing, physiotherapy, pharmacy) to assess clinical skills in examination, communication, medical procedures, and interpretation of results. The examination usually takes the form of a circuit of stations around which each candidate moves after a specified time interval (5–10 minutes) at each station. Stations are a mixture of interactive and noninteractive tasks. Some have an examiner and a simulated patient, either an actor for assessment of communication or history-taking skills or a manikin of a specific part of the body (e.g. to demonstrate how to use an auriscope). Other stations have investigation results with a list of questions that are to be completed on computer-marked examination papers. Each station has a different examiner and the stations are standardized with specific marking criteria, thus enabling fairer comparison with peers.... objective structured clinical examination

Observer Error

see validity.... observer error

Otoacoustic Emissions

(OAE, Kemp echoes) tiny sounds that emerge from the inner ear either spontaneously (spontaneous otoacoustic emissions, SOAE) or shortly after the ear is exposed to an external sound (evoked otoacoustic emissions, EOAE). An objective test of hearing has been developed using otoacoustic emissions. The test equipment creates a small sound and then detects any response from the ear. This can be done using a click stimulus (transient otoacoustic emissions, TOAE) or two separate tones (distortion product otoacoustic emissions, DPOAE). A normal response suggests that the ear is functioning and that hearing is satisfactory. All newborn children in the UK are now screened using this technique.... otoacoustic emissions

Peak Expiratory Flow Rate

(PEFR) the maximum rate at which a person can forcibly expel air from the lungs at any time, expressed usually in litres per minute (occasionally in litres per second). A low value can help diagnose asthma in the correct clinical context, and differences between the morning and evening values can also be a feature of poor control of asthma. There is a place for PEFR in the monitoring of acute exacerbations of chronic pulmonary obstructive disease (COPD) but not in the diagnosis of COPD.... peak expiratory flow rate

The main symptoms are pain in the hip or knee and limping gait. It can be diagnosed on X-ray. Treatment usually involves surgery to stabilize the epiphysis.... slipped capital femoral epiphysis

Re-entry Tachycardia

a rapid heart rate due to a self-sustaining circulation of electrical impulses from the atria to the ventricles and back again. This re-entry circuit requires the presence of an abnormal second electrical conduction pathway in addition to the usual atrioventricular nodal connection route. The abnormal pathway may be located within the *atrioventricular node (causing *atrioventricular nodal re-entry tachycardia) or it may be an *accessory pathway situated outside the atrioventricular node (causing *atrioventricular reciprocating tachycardia). Medication is often effective and *radiofrequency ablation is usually curative.... re-entry tachycardia

Toxic Epidermal Necrolysis

(TEN, Lyell’s syndrome) a severe reaction to medications with a high mortality rate. Medications causing TEN include sulfonamides, anticonvulsants, antiretrovirals, and allopurinol. Widespread separation of the dead epidermal layer from underlying skin occurs, with consequent problems due to skin failure: impaired temperature regulation, infection risk, severe pain, etc. Mucous membranes are commonly affected, including the eyes (sometimes leading to blindness), mouth, and genitalia. Multi-organ failure may occur. Treatments include stopping the offending medication, good supportive nursing (usually in an ITU or HDU setting), antibiotics where appropriate, and intravenous immunoglobulin or ciclosporin.... toxic epidermal necrolysis

Wolff–chaikoff Effect

the inhibition of thyroid hormone production by administration of large doses of iodide. This occurs at a critical dosage level below which the addition of iodide to an iodine-deficient individual results in increased production of thyroid hormone. The effect is transient in individuals with normal thyroids but may persist in thyroiditis; it can be utilized medically to induce a hypothyroid state, for example in patients with *thyroid crisis (see Lugol’s solution).

Basil, Exotic

Ocimum basilicum

FAMILY: Lamiaceae (Labiatae)

SYNONYMS: Sweet basil, Comoran basil (oil), Reunion basil (oil).

GENERAL DESCRIPTION: Botanically classified as identical from the French basil, though it is a larger plant with a harsher odour and different constituents.

DISTRIBUTION: Mainly produced in the Comoro Islands, but it is also processed in Madagascar.

OTHER SPECIES: The exotic basil is a dramatically different chemotype to the French basil and probably a seperate sub-species (possibly a form of O. canum), although this has not been specified. Essential oils are also produced in Morocco, Egypt, South Africa, Brazil and Indonesia from various chemotypes of the East Indian or shrubby basil (O. gratissimum), which contain a high percentage of either thymol or eugenol. The hairy or hoary basil (O. canum), originating in East Africa and found in India and South America, is also used to extract oils rich in either methyl cinnamate or camphor, which are produced in West and East Africa, India, the West Indies and Indonesia. See also entry on French basil.

HERBAL/FOLK TRADITION: See French Basil.

ACTIONS: See Basil French.

EXTRACTION: Essential oil by steam distillation from the leaves and flowering tops.

CHARACTERISTICS: The Exotic type oil is yellow or pale green, with a slightly coarse sweet-herbaceous odour with a camphoraceous tinge. It’s scent does not compare with the ‘true’ sweet basil oil.

PRINCIPAL CONSTITUENTS: Mainly methyl chavicol (70–88 per cent), with small amounts of linalol, cineol, camphor, eugenol, limonene and citronellol.

SAFETY DATA: Methyl chavicol is moderately toxic and irritating to the skin: ‘the methyl chavicol content of Comoran basil is sufficient reason to discard it for therapeutic usage in favour of the French type.’6 There has also been some recent concern over the possible carcinogenic effects of methyl chavicol. Basil should be avoided during pregnancy.

AROMATHERAPY/HOME: USE None.

OTHER USE The oil is employed in high class fragrances, soaps and dental products; used extensively in major food categories especially meat products and savories.... basil, exotic

Elemi

Canarium luzonicum

FAMILY: Burseraceae

SYNONYMS: C. commune, Manila elemi, elemi gum, elemi resin, elemi (oleoresin).

GENERAL DESCRIPTION: A tropical tree up to 30 metres high which yields a resinous pathological exudation with a green pungent odour. Although it is called a gum, it is almost entirely made up of resin and essential oil.

DISTRIBUTION: Native to the Philippine Islands and the Moluccas, where it is also cultivated. Distillation of the oil takes place at source.

OTHER SPECIES: There are several other species of Canarium which grow wild or are cultivated in the Philippines, which also yield a ‘gum’. It is also closely related to the trees yielding myrrh, frankincense and opopanax.

HERBAL/FOLK TRADITION: The gum or oleoresin is used locally for skin care, respiratory complaints and as a general stimulant. Elemi was one of the aromatics used by the ancient Egyptians for the embalming process.

ACTIONS: Antiseptic, balsamic, cicatrisant, expectorant, fortifying, regulatory, stimulant, stomachic, tonic.

EXTRACTION: Essential oil by steam distillation from the gum. (A resinoid and resin absolute are also produced in small quantities.)

CHARACTERISTICS: A colourless to pale yellow liquid with a light, fresh, balsamic-spicy, lemonlike odour. It blends well with myrrh, frankincense, labdanum, rosemary, lavender, lavandin, sage, cinnamon and other spices.

PRINCIPAL CONSTITUENTS: The gum contains about 10–25 per cent essential oil of mainly phellandrene, dipentene, elemol, elemicin, terpineol, carvone and terpinolene among others.

SAFETY DATA: Non-toxic, non-irritant, non-sensitizing.

AROMATHERAPY/HOME: USE

Skin care: Aged skin, infected cuts and wounds, inflammations, rejuvenation, wrinkles – signifies drying and ‘preservation’..

Respiratory system: Bronchitis, catarrhal conditions, unproductive coughs.

Nervous system: Nervous exhaustion and stress-related conditions.

OTHER USES: Resinoid and oil are used primarily as fixatives but also as fragrance components in soaps, detergents, cosmetics and perfumes. Occasionally used as a flavouring ingredient in food products, alcoholic and soft drinks.... elemi

Eucalyptus, Blue Gum

Eucalyptus globulus var. globulus

FAMILY: Myrtaceae

SYNONYMS: Gum tree, southern blue gum, Tasmanian blue gum, fever tree, stringy bark.

GENERAL DESCRIPTION: A beautiful, tall, evergreen tree, up to 90 metres high. The young trees have bluish-green oval leaves while the mature trees develop long, narrow, yellowish leaves, creamy-white flowers and a smooth, pale grey bark often covered in a white powder.

DISTRIBUTION: Native to Tasmania and Australia. Mainly cultivated in Spain and Portugal, also Brazil, California, Russia and China. Very little of this oil now comes from its native countries.

OTHER SPECIES: There are over 700 different species of eucalyptus, of which at least 500 produce a type of essential oil. Many have been extracted simply for experimental purposes, and research is still being carried out with regard to the different constituents of each oil. In general, they can be divided into three categories. 1. The medicinal oils containing large amounts of cineol (or eucalyptol), such as the blue gum, but increasingly the blue malee (E. polybractea), the narrow-leaved peppermint (E. radiata var. australiana) and the gully gum (E. smithii). 2. The industrial oils containing mainly piperitone and phellandrene, such as the peppermint eucalyptus (E. piperita), grey peppermint (E. radiata var. phellandra) and increasingly the broad-leaved peppermint (E. dives var. Type). 3. The perfumery oils containing mainly citronellal, such as the lemon-scented eucalyptus (E. citriodora). See also Botanical Classification section.

HERBAL/FOLK TRADITION: A traditional household remedy in Australia, the leaves and oil are especially used for respiratory ailments such as bronchitis and croup, and the dried leaves are smoked like tobacco for asthma. It is also used for feverish conditions (malaria, typhoid, cholera, etc.) and skin problems like burns, ulcers and wounds. Aqueous extracts are used for aching joints, bacterial dysentery, ringworms, tuberculosis, etc. and employed for similar reasons in western and eastern medicine. The wood is also used for timber production in Spain.

ACTIONS: Analgesic, antineuralgic, antirheumatic, antiseptic, antispasmodic, antiviral, balsamic, cicatrisant, decongestant, deodorant, depurative, diuretic, expectorant, febrifuge, hypoglycaemic, parasiticide, prophylactic, rubefacient, stimulant, vermifuge, vulnerary.

EXTRACTION: Essential oil by steam distillation from the fresh or partially dried leaves and young twigs.

CHARACTERISTICS: A colourless mobile liquid (yellows on ageing), with a somewhat harsh camphoraceous odour and woody-sweet undertone. It blends well with thyme, rosemary, lavender, marjoram, pine, cedarwood and lemon. (The narrow-leaved eucalyptus (E. radiata var. australiana) is often used in preference to the blue gum in aromatherapy work, being rich in cineol but with a sweeter and less harsh odour.)

PRINCIPAL CONSTITUENTS: Cineol (70–85 per cent), pinene, limonene, cymene, phellandrene, terpinene, aromadendrene, among others.

SAFETY DATA: Externally non-toxic, non-irritant (in dilution), non-sensitizing. ‘When taken internally eucalyptus oil is toxic and as little as 3.5ml has been reported as fatal’..

AROMATHERAPY/HOME: USE

Skin Care: Burns, blisters, cuts, herpes, insect bites, insect repellent, lice, skin infections, wounds.

Circulation Muscles And Joints: Muscular aches and pains, poor circulation, rheumatoid arthritis, sprains, etc.

Respiratory System: Asthma, bronchitis, catarrh, coughs, sinusitis, throat infections.

Genito-Urinary System: Cystitis, leucorrhoea.

Immune System: Chickenpox, colds, epidemics, ’flu, measles.

Nervous System: Debility, headaches, neuralgia.

OTHER USES: The oil and cineol are largely employed in the preparation of liniments, inhalants, cough syrups, ointments, toothpaste and as pharmaceutical flavourings also used in veterinary practise and dentistry. Used as a fragrance component in soaps, detergents and toiletries – little used in perfumes. Used for the isolation of cineol and employed as a flavour ingredient in most major food categories.... eucalyptus, blue gum

DISTRIBUTION: Native to Tasmania and Australia, especially New South Wales and Victoria. Oil is also produced in South Africa.

OTHER SPECIES: There are two types of broad-leaved peppermint although they look identical – one is rich in cineol (E. dives var. C.) and one is rich in ‘piperitone’ (E. dives var. Type). It is also similar to the peppermint eucalyptus (E. piperita) and the grey or narrow-leaved peppermint (E. radiata var. phellandra). See also entry on Eucalyptus, blue gum and Botanical Classification section.

HERBAL/FOLK TRADITION: The aborigines used the burning leaves in the form of a fumigation for the relief of fever; ‘heat went out of sick man and into fire’.
