Chronic Fatigue Syndrome

(CFS) is a recently designated semi-disease, often attributed to EBV (the Epstein-Barr virus) or CMV (Cytomegalovirus) infections, characterized by FUOs (Fevers of Unknown Origin) and resulting in the patient suffering FLS (Feels Like Shit). In most of us, the microorganisms involved in CFS usually provoke nothing more than a head cold; in some individuals, however, they induce a long, grinding, and debilitating disorder, characterized by exhaustion, depression, periodic fevers...a crazy-quilt of symptoms that frustrates both the sufferer and the sometimes skeptical physician. MCS (Multiple Chemical Sensitivities) are another syndrome that is often lumped with CFS, and they may often be two faces of the same condition. I am not using all these acronyms to mock the conditions, but as an irony. There is too much (Acronym Safety Syndrome) in medicine, reducing complex and frustrating conditions to insider’s techno-babble, somehow therein trivializing otherwise complex, painful and crazy-making problems. The widest use of acronyms (AIDS, HIV, CFS, MCS, MS etc.) seems to be for diseases hardest to treat, least responsive to procedural medicine, and most depressing to discuss with patients or survivors.... chronic fatigue syndrome

Dumping Syndrome

A sensation of weakness and sweating after a meal in patients who have undergone GASTRECTOMY. Rapid emptying of the stomach and the drawing of ?uid from the blood into the intestine has been blamed, but the exact cause is unclear.... dumping syndrome

Syndrome

A pattern of symptoms and signs, appearing one by one or simultaneously, that together characterise a particular disease or disorder.... syndrome

Adrenogenital Syndrome

An inherited condition, the adrenogenital syndrome – also known as congenital adrenal hyperplasia – is an uncommon disorder affecting about 1 baby in 7,500. The condition is present from birth and causes various ENZYME defects as well as blocking the production of HYDROCORTISONE and ALDOSTERONE by the ADRENAL GLANDS. In girls the syndrome often produces VIRILISATION of the genital tract, often with gross enlargement of the clitoris and fusion of the labia so that the genitalia may be mistaken for a malformed penis. The metabolism of salt and water may be disturbed, causing dehydration, low blood pressure and weight loss; this can produce collapse at a few days or weeks of age. Enlargement of the adrenal glands occurs and the affected individual may also develop excessive pigmentation in the skin.

When virilisation is noted at birth, great care must be taken to determine genetic sex by karyotyping: parents should be reassured as to the baby’s sex (never ‘in between’). Blood levels of adrenal hormones are measured to obtain a precise diagnosis. Traditionally, doctors have advised parents to ‘choose’ their child’s gender on the basis of discussing the likely condition of the genitalia after puberty. Thus, where the phallus is likely to be inadequate as a male organ, it may be preferred to rear the child as female. Surgery is usually advised in the ?rst two years to deal with clitoromegaly but parent/ patient pressure groups, especially in the US, have declared it wrong to consider surgery until the children are competent to make their own decision.

Other treatment requires replacement of the missing hormones which, if started early, may lead to normal sexual development. There is still controversy surrounding the ethics of gender reassignment.

Blind Loop Syndrome

A disorder in which abnormal FAECES occur as a result of a redundant loop in the small INTESTINE. The loop obstructs the normal ?ow of the contents of the bowel, causing stagnation. The syndrome is characterised by light-yellow, smelly, fatty, bulky faeces. The patient suffers from tiredness, malaise and loss of weight. Previous abdominal surgery is sometimes the cause, but the condition can be inherited. Blockage of intestinal contents upsets the bowel’s normal bacterial balance and hinders the normal absorption of nutrients. Treatment is either with antibiotics or, if that fails, surgery.... blind loop syndrome

Crush Syndrome

A condition in which kidney failure occurs in patients who have been the victims of severe crushing accidents (see also KIDNEYS). The fundamental injury is damage to muscle. The limb swells. The blood volume falls. Blood UREA rises; there is also a rise in the POTASSIUM content of the blood. Urgent treatment in an intensive therapy unit is required and renal dialysis may well be necessary. The patient may survive; or die with renal failure. Post-mortem examination shows degeneration of the tubules of the kidney, and the presence in them of pigment casts.... crush syndrome

Guillain-barré Syndrome

A disease of the peripheral nerves causing weakness and numbness in the limbs. It customarily occurs up to three weeks after an infection – for example, CAMPYLOBACTER infection of the gastrointestinal tract provoking an allergic response in the nerves. It may begin with weakness of the legs and gradually spread up the body. In the worst cases the patient may become totally paralysed and require to be arti?cially ventilated. Despite this, recovery is the rule.... guillain-barré syndrome

Gulf War Syndrome

A collection of varying symptoms, such as persistent tiredness, headaches, muscle pain and poor concentration, reported by members of the Coalition Armed Forces who served in the 1991 Gulf War. Whilst there is strong evidence for a health e?ect related to service, there is no evidence of a particular set of signs and symptoms (the de?nition of a ‘syndrome’) unique to those who served in the Gulf War. Symptoms have been blamed on multiple possible hazards, such as exposure to depleted uranium munitions, smoke from oil-well ?res and use of pesticides. However, the only clearly demonstrated association is with the particular pattern of vaccinations used to protect against biological weapons. Many con?icts in the past have generated their own ‘syndromes’, given names such as e?ort syndrome and shell-shock, suggesting a link to the psychological stress of being in the midst of warfare.... gulf war syndrome

Irritable Bowel Syndrome

(IBS) This is a common and generally benign condition of the colon, taking different forms but usually characterized by alternating constipation and diarrhea. There is often some pain accompanying the diarrhea phase. The bowel equivalent of spasmodic asthma, its main cause is stress, often accompanied by a history of GI infections. Adrenalin stress slows the colon and causes constipation, followed by a cholinergic rebound overstimulation of the colon. It is also called spastic colon, colon syndrome, mucous colitis, even chronic colitis. True colitis is a potentially or actually serious pathology.... irritable bowel syndrome

Nephrotic Syndrome

Nephrotic syndrome is one of PROTEINURIA, hypo-albuminaemia and gross OEDEMA. The primary cause is the leak of albumin (see ALBUMINS) through the GLOMERULUS. When this exceeds the liver’s ability to synthesise albumin, the plasma level falls and oedema results. The nephrotic syndrome is commonly the result of primary renal glomerular disease (see KIDNEYS, DISEASES OF – Glomerulonephritis). It may also be a result of metabolic diseases such as diabetic glomerular sclerosis and AMYLOIDOSIS. It may be the result of systemic autoimmune diseases such as SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) and POLYARTERITIS NODOSA. It may complicate malignant diseases such as MYELOMATOSIS and Hodgkin’s disease (see LYMPHOMA). It is sometimes caused by nephrotoxins such as gold or mercury and certain drugs, and it may be the result of certain infections such as MALARIA and CROHN’S DISEASE.... nephrotic syndrome

Premenstrual Syndrome

This has been de?ned as ‘any combination of emotional or physical features which occur cyclically in a woman before MENSTRUATION, and which regress or disappear during menstruation’. It is characterised by mood-changes, discomfort, swelling and tenderness in the breasts, swelling of the legs, a bloated feeling in the abdomen, headache, fatigue and constipation. The mood-changes range from irritability and mild depression to outbursts of violence. It may last for 3–14 days. How common it is is not known, as only the more severe cases are seen by doctors, but it has been estimated that one in ten of all menstruating women suffer from it severely enough to require treatment. The cause is not known, but it is probably due to some upset of the hormonal balance of the body. In view of the multiplicity of causes that have been put forward, it is not surprising that there is an equal multiplicity of treatments. Among these, one of the most widely used is PROGESTERONE. Others include pyridoxine, danazol, and gamma linolenic acid available in the form of oil of evening primrose. Whatever drug may be prescribed, counselling is equally essential and, in many cases, is all that is required.... premenstrual syndrome

Slapped Cheek Syndrome

See ERYTHEMA – Erythema infectiosum.... slapped cheek syndrome

Toxic Shock Syndrome

First described in 1978, this disorder is characterised by high fever, diarrhoea, SHOCK and a rash. It is frequently associated with the use of tampons (see TAMPON), but has occasionally been reported in men. The syndrome may also be linked to the use of contraceptives such as the diaphragm, cap and sponge (see under CONTRACEPTION), and skin wounds or infections may also be a cause. The disease is due to a staphylococcal toxin (see STAPHYLOCOCCUS; TOXINS). Treatment consists of supportive measures to combat shock and eradication of the staphylococcus by ANTIBIOTICS. The design of tampons has been improved. Recurrence of the disorder has been reported and women who have had an episode should stop using tampons and vaginal contraceptives.... toxic shock syndrome

Cushing’s Syndrome

A glandular disorder occurring mostly in females, aged 30 to 50.

Causes: a tumour on the adrenal glands or excessive medication with large doses of corticosteroid drugs to make up for adrenal insufficiency. There is diminished resistance to infection. (Echinacea)

Symptoms. Fat plethoric ‘moon’ face. Limbs thin, trunk obese. Skin easily bruises (Arnica). Fatigue, weakness, pink streaks on skin. Cessation of menstruation. Loss of sex drive in men. High blood pressure and sugar in the urine are common. Bone softening leads to pain. Acne (Agnus Castus). Excess body hair. Personality change.

Treatment. Adrenal stimulants may obviate surgery or irradiation to the adrenal glands: they include Ginseng, Liquorice, Sarsaparilla, Holy Thistle (Hyde), Samphire (Hyde).

Men. Tinctures. Formula. Ginseng 3; Sarsaparilla 2; Liquorice 1. One to two teaspoons in water thrice daily.

Women. Tinctures. Formula. Agnus Castus 2; Helonias 2; Pulsatilla 1. One to two teaspoons in water thrice daily.

Good responses have been observed from Pulsatilla and Black Cohosh. ... cushing’s syndrome

Down’s Syndrome

Mongolism. Trisomy 21. Not a disease but a defect in mental and physical development. In the normal human being there are 46 chromosomes; in Down’s there are 47 – one extra No 21 chromosome. The syndrome increases with the age of the mother after the age of 35. Over the age of 40 the chances of a mother having such a child are 1-2 per cent. Children with the defect have low levels of zinc.

Cases of Down’s have followed use of nonoxynol-9 (vaginal contraceptive device) such as the polyurethane sponge. The sponge. when left in situ for a long time, may cause Down’s to follow.

Certain physical characteristics are present. The most important feature is impaired mental development. Almost all are coeliacs.

Symptoms. Low IQ, short fingers, small flat head, flattened nose, low-set ears. May be subject to umbilical hernia, and heart disease. No treatment can cure, but certain herb teas rich in minerals (Alfalfa, Red Clover) together with Kelp (either in tablet or powder form) may help children, with possible improvements in IQ. Vitamin supplements – A, D, Thiamine, Riboflavin, B6, B12, C and E improve a child’s physical and mental health – as do also the minerals: Magnesium, Calcium, Zinc, Manganese, Copper, Iron and Iodine.

Children with Down’s syndrome run an increased risk of coeliac disease, due to disturbed immunity. A substantial evidence is held in America that links a low level of Selenium in the mother. Unnecessary X- rays should be avoided. Ensure fitness before conception by gentle exercise and nutrients: Folic Acid, Selenium and Zinc.

Children with the condition are noted for their happy disposition and warmth of feeling towards others. ... down’s syndrome

Marfan’s Syndrome

A collagen disease in infants (hereditary) with lax joints permitting easy dislocation and strain.

Features: long fingers and arm span, high palate, kyphosis, etc.

Symptoms. Backache, pain in joints, dislocations.

Alternatives. Alfalfa, Fenugreek, Irish Moss, Kelp, Horsetail, Marshmallow, Bamboo gum.

Teas. Alfalfa, Comfrey leaves, Horsetail, Plantain, Silverweed. Any one: 1 heaped teaspoon to each cup boiling water; infuse 10-15 minutes. 1 cup thrice daily.

Decoction. Fenugreek seeds 2; Horsetail 1; Bladderwrack 1; Liquorice half. Prepare: 3 heaped teaspoons to 1 pint (500ml) water gently simmered 10 to 20 minutes. 1 wineglass thrice daily. Fenugreek seeds decoction.

Diet. High protein, oily fish.

Supplements. Calcium, Dolomite, Zinc. ... marfan’s syndrome

Carpal Tunnel Syndrome

A condition characterised by attacks of pain and tingling in the ?rst three or four ?ngers of one or both hands. The attacks usually occur at night. Carpal tunnel syndrome is caused by pressure on the median nerve as it passes under the strong ligament that lies across the front of the wrist. The condition may respond to use of a night splint on the hand; otherwise a corticosteroid injection under the ligament may help. If not, pressure is relieved by surgical division of the compressing ligament.... carpal tunnel syndrome

Compression Syndrome

See MUSCLES, DISORDERS OF.... compression syndrome

Haemolytic Uraemic Syndrome

A disease of children resulting in acute RENAL failure. A febrile illness of the gastrointestinal or respiratory tracts is followed by intravascular COAGULATION of blood which results in HAEMOLYSIS, ANAEMIA, THROMBOCYTOPAENIA and renal failure (resulting from ?brin deposition in renal arterioles and glomerular capillaries).

The death rate is 2–10 per cent and the majority of patients survive without renal failure. The longer the period of OLIGURIA, the greater the risk of chronic renal failure.

Treatment is supportive, with replacement of blood and clotting factors, control of HYPERTENSION, and careful observation of ?uid balance.... haemolytic uraemic syndrome

Hellp Syndrome

A type of severe PRE-ECLAMPSIA (a disorder affecting some pregnant women) that affects various systems in the body. HAEMOLYSIS, raised concentration of the enzymes in the LIVER, and a low blood platelet count are among the characteristics (and explain the name HELLP); patients are acutely ill and immediate termination of pregnancy is necessary. (See also PREGNANCY AND LABOUR.)... hellp syndrome

Irritable Bowel Syndrome (ibs)

A disorder of the intestinal tract that affects its motility and causes abdominal distension and irregular defaecation. Traditional, but now discarded, names have been spastic or irritable colon. The disease affects around 20 per cent of the general population but in most it is no more than a minor nuisance. The causes are not fully understood, but it is generally believed that symptoms develop in response to psychological factors, changed gastrointestinal motility, or altered visceral sensation. About 50 per cent of patients meet criteria for a psychiatric diagnosis. Anxiety, depression, neurosis, panic attacks, acute disease are among possible triggering factors. Some patients have diarrhoea, others are constipated, and some alternate between the two. Many have increased sensitivity to distension of the intestine. Dietary factors such as intolerance to dairy products and wheat are apparent in certain patients.

Common features of IBS include:

abdominal distension.

altered bowel habit.

colicky lower abdominal pain, eased by defaecation.

mucous discharge from rectum.

feelings of incomplete defaecation.

Investigations usually produce normal results. Positive diagnosis in people under 40 is usually straightforward. In older patients, however, barium ENEMA, X-rays and COLONOSCOPY should be done to exclude colorectal cancer.

Reassurance is the initial and often e?ective treatment. If this fails, treatment should be directed at the major symptoms. Several months of the antidepressant amitriptyline (see ANTIDEPRESSANT DRUGS) may bene?t patients with intractable symptoms, given at a dose lower than that used to treat depression. The majority of patients follow a relapsing/remitting course, with episodes provoked by stressful events in their daily lives. (See also INTESTINE, DISEASES OF.)... irritable bowel syndrome (ibs)

Locked-in Syndrome

This describes a condition in which a patient is awake and retains the power of sense perception, but is unable to communicate except by limited eye movements because the motor nervous system is paralysed. Several diseases can cause this syndrome, which results from interruption of some of the nerve tracts between the mid brain and the pons (see BRAIN). Sometimes the syndrome is caused by severe damage to muscles or the nerves enervating them. Locked-in syndrome may sometimes be confused with a PERSISTENT VEGETATIVE STATE (PVS).... locked-in syndrome

Malabsorption Syndrome

This term includes a multiplicity of diseases, all of which are characterised by faulty absorption from the INTESTINE of essential foodstu?s such as fat, vitamins and mineral salts. Among the conditions in this syndrome are COELIAC DISEASE, SPRUE, CYSTIC FIBROSIS and pancreatitis (see PANCREAS, DISORDERS OF). Surgical removal of the small intestine also causes the syndrome. Symptoms include ANAEMIA, diarrhoea, OEDEMA, vitamin de?ciencies, weight loss and, in severe cases, MALNUTRITION.... malabsorption syndrome

Mendelson Syndrome

Inhalation of regurgitated stomach contents, usually as a complication of general ANAESTHESIA. It may cause death from ANOXIA or result in extensive lung damage.... mendelson syndrome

Plummer-vinson Syndrome

Hypochromic ANAEMIA and di?culty in swallowing due to an oesophageal web.... plummer-vinson syndrome

Post-viral Fatigue Syndrome

See MYALGIC ENCEPHALOMYELITIS (ME).... post-viral fatigue syndrome

Polycystic Ovary Syndrome

Characterised by scanty (or absent) MENSTRUATION, INFERTILITY, hirsutism (excessive hairiness) and OBESITY and the sufferers often have multiple cysts in their OVARIES.

The condition is caused by an imbalance between LUTEINISING HORMONE (LH) and FOLLICLE-STIMULATING HORMONE (FSH); this imbalance stops OVULATION and varies the TESTOSTERONE output of the ovaries. The treatment may be with CLOMIPHENE; with a PROGESTOGEN drug; with LUTEINISING HORMONE-RELEASING HORMONE (LHRH); or with oral contraceptives (see under CONTRACEPTION – Non-barrier methods). The treatment chosen depends on the severity of the disease and whether the woman wants to conceive. Rarely a section of ovarian tissue is surgically removed.... polycystic ovary syndrome

Respiratory Distress Syndrome

This may occur in adults as ACUTE RESPIRATORY DISTRESS SYNDROME (ARDS), or in newborn children, when it is also known as HYALINE MEMBRANE DISEASE. The adult syndrome consists of PULMONARY OEDEMA of non-cardiac origin. The process begins when tissue damage stimulates the autonomic nervous system, releases vasoactive substances, precipitates complement activation, and produces abnormalities of the clotting cascade – the serial process that leads to clotting of the blood (see COAGULATION). The activation of complement causes white cells to lodge in the pulmonary capillaries where they release substances which damage the pulmonary endothelium.

Respiratory distress syndrome is a complication of SHOCK, systemic SEPSIS and viral respiratory infections. It was ?rst described in 1967, and – despite advances with assisted ventilation

– remains a serious disease with a mortality of more than 50 per cent. The maintenance of adequate circulating blood volume, peripheral PERFUSION, acid-base balance and arterial oxygenation is important, and assisted ventilation should be instituted early.

In newborns the mechanism is diferent, being provoked by an inability of the lungs to manufacture SURFACTANT.... respiratory distress syndrome

Restless Legs Syndrome

A condition in which the patient experiences unpleasant sensations, and occasionally involuntary movements, in the legs when at rest, especially at night. No pathological changes have been identi?ed. It is sometimes indicative of iron-de?ciency ANAEMIA, but in many cases the cause remains a mystery and the variety of cures o?ered are a testimony to this. Some anti-epileptic drugs are said to help (see EPILEPSY).... restless legs syndrome

Seasonal Affective Disorder Syndrome

Known colloquially as SADS, this is a disorder in which an affected individual’s mood changes with the seasons. He or she is commonly depressed in winter, picking up again in the spring. The diagnosis is controversial and its prevalence is not known. The mood-change is probably related to light, with MELATONIN playing a key role. (See also MENTAL ILLNESS.)... seasonal affective disorder syndrome

Stokes-adams Syndrome

A term applied to a condition in which slowness of the PULSE is associated with attacks of unconsciousness, and which is due to ARRHYTHMIA of the cardiac muscle or even complete heart block. Usually the heart returns to normal rhythm after a short period, but patients who suffer from the condition are commonly provided with a PACEMAKER to maintain normal cardiac function (see also CARDIAC PACEMAKER).... stokes-adams syndrome

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. Treatment is by surgery.... zollinger-ellison syndrome

Carcinoid Syndrome

Flushing of the face and neck caused by an active malignant tumour in the stomach or intestines with secondary growths in the liver. Often accompanied by an explosive diarrhoea. The lesion is usually found in the ileum yet it may also appear in the bile duct, ovaries or bronchi. Other symptoms include low blood pressure, drastic reduction in weight due to loss of body fluids.

Symptoms: flushing of face and neck, diarrhoea, low blood pressure, weight loss.

Treatment: relief of symptoms only. Diarrhoea – Fenugreek seed tea. Flushing: Chamomile tea.

Vitamin and Mineral Supplementation: Because of severe drain on these food elements Multivitamins should be taken daily together with additional 1000ius Vitamin E for the disturbed circulatory system. The heart should be sustained with a preparation of the Hawthorn berry.

To be treated by or in liaison with a qualified medical practitioner. ... carcinoid syndrome

Asperger’s Syndrome

A rare developmental disorder that is usually first recognized in childhood because of difficulties with social interactions, stilted speech, and very specialized interests.

Intelligence is normal or high.

Asperger’s syndrome is considered to be an autistic spectrum disorder and is also known as pervasive developmental disorder.

Special educational support may be needed, often within mainstream education.

The condition is lifelong.... asperger’s syndrome

Behçet’s Syndrome

A rare, multisystem disorder with recurrent mouth ulcers and genital ulcers and inflammation of the eyes, skin joints, blood vessels, brain, and intestines. The cause of Behçet’s syndrome is unknown, but it is strongly associated with a genetically determined histocompatability antigen, -B51. Treatment is difficult and may require corticosteroid and immunosuppressant drugs. The condition often becomes long-term.... behçet’s syndrome

Compartment Syndrome

A painful cramp due to compression of a group of muscles within a confined space. It may occur when muscles are enlarged due to intensive training or injury such as shin splints. Cramps induced by exercise usually disappear when exercise is stopped. Severe cases may require fasciotomy to improve blood flow and prevent development of a permanent contracture.... compartment syndrome

Conn’s Syndrome

A disorder caused by the secretion of excessive amounts of the hormone aldosterone by a noncancerous tumour of one of the adrenal glands. (See also aldosteronism.)... conn’s syndrome

Cri Du Chat Syndrome

A rare, congenital condition of severe mental handicap, abnormal facial appearance, low birth weight, and short stature, which is characterized by a cat-like cry in infancy. The syndrome is caused by a chromosomal abnormality. There is no treatment. (See also genetic counselling.)... cri du chat syndrome

Fanconi’s Syndrome

A rare kidney disorder that occurs most commonly in childhood. Various important chemicals, such as amino acids, phosphate, calcium, and potassium, are lost in the urine, leading to failure to thrive, stunting of growth, and bone disorders such as rickets. Possible causes of the syndrome include several rare inherited abnormalities of body chemistry and an adverse reaction to certain drugs.

The child may resume normal growth if an underlying chemical abnormality can be corrected. Alternatively, a kidney transplant may be possible.... fanconi’s syndrome

Fragile X Syndrome

An inherited defect of the X chromosome that causes learning difficulties.

The disorder occurs within families according to an X-linked recessive pattern of inheritance (see genetic disorders).

Although mainly males are affected, women can become carriers of the genetic defect.

In addition to having learning difficulties, affected males tend to be tall and physically strong, with large testes, a prominent nose and jaw, increased ear length, and are prone to epileptic seizures.

About a third of female carriers show some intellectual impairment.

The condition cannot be treated.... fragile x syndrome

Ganser’s Syndrome

A rare factitious disorder in which a person seeks, consciously or unconsciously, to mislead others about his or her mental state and may simulate symptoms of psychosis.... ganser’s syndrome

Gilles De La Tourette’s Syndrome

A rare, inherited neurological disorder.

It starts in childhood with repetitive grimaces and tics.

Involuntary barks, grunts, or other noises may appear as the disease progresses.

In some cases, the sufferer has episodes of issuing foul language.

The syndrome is more common in males.

It is usually of lifelong duration, but antipsychotic drugs can help in some cases.... gilles de la tourette’s syndrome

Goodpasture’s Syndrome

A rare autoimmune disorder causing inflammation of the glomeruli in the kidney (see glomerulus) and the alveoli in the lungs, and anaemia. It is a serious disease; unless treated early it may lead to lifethreatening bleeding into the lungs and progressive kidney failure. The disease is most common in young men, but can develop at any age and in women. Sometimes, it responds to treatment with immunosuppressant drugs and plasmapheresis. People who have severe or repeated attacks require dialysis and, eventually, a kidney transplant.... goodpasture’s syndrome

Horner’s Syndrome

A group of physical signs (narrowing of the eye pupil, drooping of the eyelid, and absence of sweating) affecting 1 side of the face that indicates damage to part of the sympathetic nervous system (see autonomic nervous system).... horner’s syndrome

Hurler’s Syndrome

A rare, inherited condition caused by an enzyme defect. The syndrome is a type of inborn error of metabolism (see metabolism, inborn errors of) in which there is an abnormal accumulation of substances known as mucopolysaccharides in the tissues.

Affected children may appear normal at birth but, at 6–12 months of age, they develop cardiac abnormalities, umbilical hernia, skeletal deformities, and enlargement of the tongue, liver, and spleen.

Growth is limited and mental development slows.

If the condition is diagnosed in early infancy, a bone marrow transplant may be curative.... hurler’s syndrome

Klinefelter’s Syndrome

A chromosomal abnormality in which a male has 1, or occasionally more, extra X chromosomes in his cells, giving a complement of instead of. The risk of a baby having the condition increases with maternal age. Features of the syndrome vary in severity and may not become apparent until puberty, when gynaecomastia (breast enlargement) occurs and the testes remain small. Affected males are usually infertile (see infertility). They tend to be tall and thin with a female body shape and absence of body hair. Incidence of learning difficulties is higher in people with Klinefelter’s syndrome than in the general population. There is no cure for the disorder, but hormonal treatment can induce secondary sexual characteristics, and mastectomy may be used to treat gynaecomastia.... klinefelter’s syndrome

Munchausen’s Syndrome

A chronic factitious disorder in which the sufferer complains of physical symptoms that are pretended or self-induced in order to play the role of patient. Most afflicted people are repeatedly hospitalized.

The usual complaints are abdominal pain, bleeding, neurological symptoms, rashes, and fever. Sufferers typically invent dramatic histories and behave disruptively in hospital. Many have detailed medical knowledge and scars from self-injury or previous treatment. In Munchausen’s syndrome by proxy, parents cause factitious disorders in their children.

Treatment consists of protecting sufferers from unnecessary operations and drug treatments.... munchausen’s syndrome

Nelson’s Syndrome

A rare disorder of the endocrine system that causes increased skin pigmentation. Nelson’s syndrome results from enlargement of the pituitary gland, which can follow removal of the adrenal glands (a treatment for Cushing’s syndrome).

Nelson’s syndrome is treated by hypophysectomy (removal or destruction of the pituitary gland).... nelson’s syndrome

Rett’s Syndrome

A brain disorder, thought to be a genetic disorder, that only affects girls. Symptoms usually occur when the child is 12–18 months old. Acquired skills, such as walking and communication skills, disappear and the girl becomes progressively handicapped, perhaps with signs of autism. There are repetitive writhing movements of the hands and limbs, and inappropriate outbursts of crying or laughter. There is no cure for Rett’s syndrome and sufferers need constant care and attention. Parents of an affected child should receive genetic counselling.... rett’s syndrome

Reiter’s Syndrome

A condition in which there is a combination of urethritis, reactive arthritis, and conjunctivitis. There may also be uveitis. Reiter’s syndrome is more common in men.

The syndrome is caused by an immune response and usually develops only in people with a genetic predisposition. Most patients have the -B27 tissue type (see histocompatability antigens). The syndrome’s development is induced by infection: usually nongonococcal urethritis, but sometimes bacillary dysentery. Reiter’s syndrome usually starts with a urethral discharge, which is followed by conjunctivitis and then arthritis. The arthritis usually affects 1 or 2 joints (usually the knee and/or ankle) and is often associated with fever and malaise. Attacks can last for several months. Tendons, ligaments, and tissue in the soles of the feet may also become inflamed. Skin rashes are common.

Diagnosis is made from the symptoms.

Analgesic drugs and nonsteroidal antiinflammatory drugs relieve symptoms but may have to be taken for a long period.

Relapses occur in about 1 in 3 cases.... reiter’s syndrome

Reye’s Syndrome

A rare disorder in which brain and liver damage follow a viral infection. Children over 15 are rarely affected. The cause is unknown, but aspirin seems to be a predisposing factor to developing the condition and is therefore not recommended for children.

The disorder starts as the child recovers from the infection. Symptoms include uncontrollable vomiting, lethargy, memory loss, and disorientation. Swelling of the brain may cause seizures, disturbances in heart rhythm, coma, and cessation of breathing.

Brain swelling may be controlled by corticosteroid drugs and by intravenous infusions of mannitol. Dialysis or blood transfusions may be needed. If breathing stops, a ventilator is used.

The death rate is around 10 per cent, and higher for those who have seizures, lapse into deep coma, and stop breathing.

Permanent brain damage may occur.... reye’s syndrome

Sézary Syndrome

A rare condition in which there is an abnormal overgrowth of lymphocytes in the skin, liver, spleen, and lymph nodes. It mainly affects middleaged and elderly people. The first symptom is the appearance of red, scaly patches on the skin that spread to form an itchy, flaking rash. There may also be accumulation of fluid under the skin, baldness, and distorted nail growth. Sézary syndrome is sometimes associated with leukaemia. Treatment includes anticancer drugs and radiotherapy.... sézary syndrome

Sjögren’s Syndrome

A condition in which the eyes and mouth are excessively dry.

The nasal cavity, throat, and vagina may also be affected.

The syndrome tends to occur with certain autoimmune disorders, such as rheumatoid arthritis and systemic lupus erythematosus.

Most sufferers are middle-aged women.... sjögren’s syndrome

Stein-leventhal Syndrome

See ovary, polycystic.... stein-leventhal syndrome

Subclavian Steal Syndrome

Recurrent attacks of blurred or double vision, loss of coordination, or dizziness caused by reduced blood flow to the base of the brain when one arm (usually the left) is moved.

The cause is narrowing of the arteries that carry blood to the arms, usually due to atherosclerosis.

Treatment is by arterial reconstructive surgery.... subclavian steal syndrome

Sudden Infant Death Syndrome

The sudden, unexpected death of an infant that cannot be explained.

Possible risk factors include: laying the baby face-down to sleep; overheating; parental smoking after the birth; prematurity and low birth weight; and poor socioeconomic background.

Preventive measures include: ensuring that the baby sleeps on its back at the foot of the cot; regulating the baby’s temperature (using the same amount of clothing and blankets that an adult would need); and stopping smoking.... sudden infant death syndrome

Temporomandibular Joint Syndrome

Pain and other symptoms affecting the head, jaw, and face, thought to result when the temporomandibular joints and the muscles and ligaments attached to them do not work together correctly. Causes include spasm of the chewing muscles, an incorrect bite (see malocclusion), jaw, head, or neck injuries, or osteoarthritis. Common symptoms include headaches, tenderness of the jaw muscles, and aching facial pain. Treatment involves correction of any underlying abnormality, analgesic drugs, and, in some cases, injection of corticosteroid drugs into the joint.... temporomandibular joint syndrome

Testicular Feminization Syndrome

A rare inherited condition in which a genetic male with internal testes has the external appearance of a female. The syndrome is a form of intersex and is the most common form of male pseudohermaphroditism.

The cause is a defective response of the body tissues to testosterone.

The causative genes are carried on the X chromosome, and so females can be carriers. Affected individuals appear to be girls throughout childhood, and most develop female secondary sexual characteristics at puberty; but amenorrhoea occurs, and a diagnosis is usually made during investigations to find its cause. Chromosome analysis shows the presence of male chromosomes and blood tests show male levels of testosterone. Treatment of testicular feminization syndrome involves surgical removal of the testes, to prevent cancerous change in later life, and therapy with oestrogen drugs. An affected person is not fertile but can live a normal life as a woman.... testicular feminization syndrome

Tietze’s Syndrome

Chest pain localized to an area on the front of the chest wall, usually made worse by movement of the arms or trunk or by pressure on the chest wall. The syndrome is caused by inflammation of 1 or several rib cartilages and symptoms may persist for months. Treatment is with analgesics, nonsteroidal anti-inflammatory drugs, or local injections of corticosteroid drugs into the cartilage.... tietze’s syndrome

Turner’s Syndrome

A disorder caused by a chromosomal abnormality that only affects females. The abnormality may arise in 1 of 3 ways: affected females may have only 1 X chromosome instead of 2; they may have 1 normal and 1 defective X chromosome; or they may have a mixture of cells (see mosaicism), in which some of the cells are missing an X chromosome, some have extra chromosomes, and others have the normal complement of chromosomes. Turner’s syndrome causes short stature; webbing of the skin of the neck; absence or retarded development of sexual characteristics; amenorrhea, coarctation of the aorta, and abnormalities of the eyes and bones.

Treatment with growth hormone from infancy helps girls with Turner’s syndrome to achieve near normal height. Coarctation of the aorta is treated surgically. Treatment with oestrogen drugs induces menstruation, but it does not make affected girls fertile.... turner’s syndrome

Acquired Immune Deficiency Syndrome (aids)

A severe manifestation of infection with the Human immunodeficiency virus (HIV).... acquired immune deficiency syndrome (aids)

Acute Respiratory Distress Syndrome (ards)

Formerly known as adult respiratory distress syndrome. A form of acute respiratory failure in which a variety of di?erent disorders give rise to lung injury by what is thought to be a common pathway. The condition has a high mortality rate (about 70 per cent); it is a complex clinical problem in which a disproportionate immunological response plays a major role. (See IMMUNITY.)

The exact trigger is unknown, but it is thought that, whatever the stimulus, chemical mediators produced by cells of the immune system or elsewhere in the body spread and sustain an in?ammatory reaction. Cascade mechanisms with multiple interactions are provoked. CYTOTOXIC substances (which damage or kill cells) such as oxygen-free radicals and PROTEASE damage the alveolar capillary membranes (see ALVEOLUS). Once this happens, protein-rich ?uid leaks into the alveoli and interstitial spaces. SURFACTANT is also lost. This impairs the exchange of oxygen and carbon dioxide in the lungs and gives rise to the clinical and pathological picture of acute respiratory failure.

The typical patient with ARDS has rapidly worsening hypoxaemia (lack of oxygen in the blood), often requiring mechanical ventilation. There are all the signs of respiratory failure (see TACHYPNOEA; TACHYCARDIA; CYANOSIS), although the chest may be clear apart from a few crackles. Radiographs show bilateral, patchy, peripheral shadowing. Blood gases will show a low PaO2 (concentration of oxygen in arterial blood) and usually a high PaCO2 (concentration of carbon dioxide in arterial blood). The lungs are ‘sti?’ – they are less e?ective because of the loss of surfactant and the PULMONARY OEDEMA.

Causes The causes of ARDS may be broadly divided into the following:... acute respiratory distress syndrome (ards)

Asperger’s Syndrome

A lifelong personality disorder, evident from childhood and regarded as a mild form of AUTISM. Persons with the syndrome tend to have great di?culty with personal relationships. They tend to take what is said to them as literal fact and have great di?culty in understanding irony, metaphors or even jokes. They appear shy with a distant and aloof character, emotional rigidity and inability to adapt to new situations. They are often mocked and ill-treated at school by their fellows because they appear unusual. Many people with Asperger’s seem to take refuge in intense interests or hobbies, often conducted to an obsessional degree. Many become skilled in mathematics and particularly information technology. Frustration with the outside world which is so hard to comprehend may provoke aggressive outbursts when stressed.... asperger’s syndrome

Behçet’s Syndrome

This is a syndrome characterised by oral and genital ulceration, UVEITIS and ARTHROPATHY. THROMBOPHLEBITIS is a common complication, and involvement of the central nervous system may occur.... behçet’s syndrome

Attention Deficit Disorder (hyperactivity Syndrome)

A lifelong disorder characterised by overactive behaviour, short attention span and poor concentration. It is thought to be caused by a minor abnormality that affects the part of the brain that allows us to concentrate and focus on tasks. Some scientists have suggested that it may be caused by particular foods, particularly processed foods containing arti?cial additives, and recommend special diets. In some countries, attention de?cit disorder is diagnosed in up to a tenth of all children; this may re?ect di?erences in paediatric practice and diagnosis rather than a real variation in prevalence of the disorder. Behaviour therapy is the main treatment. Those children with very severe symptoms of restlessness, short attention span and disturbed behaviour may respond to additional treatment with methylphenidate (Ritalin®). This is an amphetamine-like drug that is thought to stimulate the part of the brain that is not working properly. Use of this drug has, however, been controversial.... attention deficit disorder (hyperactivity syndrome)

Chronic Fatigue Syndrome (cfs)

See also MYALGIC ENCEPHALOMYELITIS (ME). A condition characterised by severe, disabling mental and physical fatigue brought on by mental or physical activity and associated with a range of symptoms including muscle pain, headaches, poor sleep, disturbed moods and impaired concentration. The prevalence of the condition is between 0.2 and 2.6 per cent of the population (depending on how investigators de?ne CFS/ME). Despite the stereotype of ‘yuppie ?u’, epidemiological research has shown that the condition occurs in all socioeconomic and ethnic groups. It is commoner in women and can also occur in children.

In the 19th century CFS was called neurasthenia. In the UK, myalgic encephalomyelitis (ME) is often used, a term originally introduced to describe a speci?c outbreak such as the one at the Royal Free Hospital, London in 1955. The term is inaccurate as there is no evidence of in?ammation of the brain and spinal cord (the meaning of encephalomyelitis). Doctors prefer the term CFS, but many patients see this as derogatory, perceiving it to imply that they are merely ‘tired all the time’ rather than having a disabling illness.

The cause (or causes) are unknown, so the condition is classi?ed alongside other ‘medically unexplained syndromes’ such as IRRITABLE BOWEL SYNDROME (IBS) and multiple chemical sensitivity – all of which overlap with CFS. In many patients the illness seems to start immediately after a documented infection, such as that caused by EPSTEIN BARR VIRUS, or after viral MENINGITIS, Q FEVER and TOXOPLASMOSIS. These infections seem to be a trigger rather than a cause: mild immune activation is found in patients, but it is not known if this is cause or e?ect. The body’s endocrine system is disturbed, particularly the hypothalamopituitary-adrenal axis, and levels of cortisol are often a little lower than normal – the opposite of what is found in severe depression. Psychiatric disorder, usually depression and/or anxiety, is associated with CFS, with rates too high to be explained solely as a reaction to the disability experienced.

Because we do not know the cause, the underlying problem cannot be dealt with e?ectively and treatments are directed at the factors leading to symptoms persisting. For example, a slow increase in physical activity can help many, as can COGNITIVE BEHAVIOUR THERAPY. Too much rest can be harmful, as muscles are rapidly weakened, but aggressive attempts at coercing patients into exercising can be counter-productive as their symptoms may worsen. Outcome is in?uenced by the presence of any pre-existing psychiatric disorder and the sufferer’s beliefs about its causes and treatment. Research continues.... chronic fatigue syndrome (cfs)

Da Costa’s Syndrome

See EFFORT SYNDROME.... da costa’s syndrome

Effort Syndrome

Also known as Da Costa’s syndrome, this is a condition in which symptoms occur, such as palpitations and shortness of breath, which are attributed by the patient to disorder of the heart. There is no evidence, however, of heart disease, and psychological factors are thought to be of importance. (See PSYCHOSOMATIC DISEASES.)... effort syndrome

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

False-memory Syndrome

Fetal Alcohol Syndrome

A disorder of newborn infants that is caused by the toxic effects on the growing FETUS of excessive amounts of alcohol taken by the mother. Low birth-weight and retarded growth are the main consequences, but affected babies may have hand and facial deformities and are sometimes mentally retarded.... fetal alcohol syndrome

Cushing’s Syndrome

Described in 1932 by Harvey Cushing, the American neurosurgeon, Cushing’s syndrome is due to an excess production of CORTISOL. It can thus result from a tumour of the ADRENAL GLANDS secreting cortisol, or from a PITUITARY GLAND tumour secreting ACTH and stimulating both adrenal cortexes to hypertrophy and secrete excess cortisol. It is sometimes the result of ectopic production of ACTH from non-endocrine tumours in the LUNGS and PANCREAS.

The patient gains weight and the obesity tends to have a characteristic distribution over the face, neck, and shoulder and pelvic girdles. Purple striae develop over the abdomen and there is often increased hairiness or hirsutism. The blood pressure is commonly raised and the bone softens as a result of osteoporosis. The best test to establish the diagnosis is to measure the amount of cortisol in a 24-hourly specimen of urine. Once the diagnosis has been established, it is then necessary to undertake further tests to determine the cause.... cushing’s syndrome

Down’s (down) Syndrome

A genetic disorder in which the affected person usually carries an extra chromosome – 47 instead of the usual 46. The extra chromosome occurs in the no. 21 group, hence the disorder is described as trisomy 21. The condition was named after Dr J L H Down, the London doctor who ?rst described it in 1866. The incidence is around one in 600 births. The disorder is characterised by a particular physical appearance and learning diffculties, with the affected individuals having an INTELLIGENCE QUOTIENT (IQ) ranging from 30 to 80 (normal is 100). Most people with the syndrome have eyes that slope up at the outer corners with skin folds that cover the inner ones. The face and features are smaller than normal, while the tongue is larger; the back of the head is ?attened and the hands are usually short and broad. The facial features led to the syndrome being described as ‘mongolism’, a term that is no longer used.

Children with Down’s syndrome are usually friendly and ?t in well with the family. Despite their learning disabilities, some learn to read and, if they have appropriate educational and environmental stimulation, can make the most of their abilities.

A heart defect is present in around 25 per cent of the children at birth, and deafness and acute LEUKAEMIA occur more frequently than in unaffected youngsters. Those with the syndrome are particularly prone to developing ear infections. ATHEROSCLEROSIS often develops early in adults and ALZHEIMER’S DISEASE tends to occur as early as 40 years of age. A friendly home environment helps them to enjoy life, but a few individuals with the syndrome may eventually require institutional care. Improved social and medical care means that many now live until their 60s.

Routine screening tests early in pregnancy, starting with blood analysis but going on if necessary to AMNIOCENTESIS and chorionic villus sampling (see PRENATAL SCREENING OR DIAGNOSIS), can identify fetuses likely to develop the disorder. If a sample of fetal cells con?rms the chromosome defect (triple marker test – see PREGNANCY AND LABOUR), the parents may consider termination of the pregnancy. In the UK, screening is normally o?ered to women over 35 because of their increased risk. When younger parents have a child with Down’s syndrome, the chances of a subsequent child with the disorder are relatively high as it is probable that both parents carry a chromosome abnormality insu?cient to cause ill-health until combined. So they may wish to discuss with their medical advisers the question of further pregnancies.

Parents who have a child with Down’s syndrome will understandably feel a combination of strong emotions, including anger and guilt, and constructive counselling can be valuable. Among societies o?ering advice and support is the Down’s Syndrome Association.... down’s (down) syndrome

Fibromyalgia Syndrome

Symptoms These vary, with pain and fatigue generally prominent, sometimes causing considerable disability. Patients can usually dress and wash independently but cannot cope with a job or household activities. Pain is mainly axial, but may affect any region. ANALGESICS, NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS) and local physical treatments are generally ine?ective.

Patients often have a poor sleep pattern, waking exhausted. Unexplained headache, urinary frequency and abdominal symptoms are common, but no cause has been found. Patients generally score highly on measures of anxiety and DEPRESSION. Fibromyalgia is not an ideal description; idiopathic di?use-pain syndrome and non-restorative sleep disorder are increasingly preferred terms.

Clinical ?ndings are generally unremarkable; most important is the presence of multiple hyperalgesic tender sites (e.g. low cervical spine, low lumbar spine, suboccipital muscle, mid upper trapezius, tennis-elbow sites, upper outer quadrants of buttocks, medial fat pad of knees). In ?bromyalgia, hyperalgesia (excessive discomfort) is widespread and symmetrical, but absent at sites normally non-tender. Claims by patients to be tender all over are more likely to be due to fabrication or psychiatric disturbance. OSTEOARTHRITIS and periarticular syndrome are much more common and should be excluded, together with other conditions, such as hypothyroidism (see THYROID GLAND, DISEASES OF), SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) and in?ammatory myopathy (see MUSCLES, DISORDERS OF), which may present with similar symptoms.

Cause There is no investigational evidence of in?ammatory, metabolic or structural abnormality, and the problem seems functional rather than pathological. SEROTONIN de?ciency has a signi?cant role in ?bromyalgia syndrome.

Management Controlled trials have con?rmed the usefulness of low-dose AMITRIPTYLINE or DOTHIEPIN together with a graded exercise programme to increase aerobic ?tness. How this works is still unclear; its e?cacy may be due to its normalising effects on the sleep centre or ‘pain gating’ (reduction of pain sensation) at the spinal-cord level. Prognosis is often poor. Nevertheless, suitable advice and training can help most patients to learn to cope better with their condition and avoid unnecessary investigations and drug treatments.... fibromyalgia syndrome

Gilles De La Tourette’s Syndrome

Also known as Tourette’s syndrome, this is a hereditary condition of severe and multiple tics (see TIC) of motor or vocal origin. It usually starts in childhood and becomes chronic (with remissions). With a prevalance of one in 2,000, a dominant gene (see GENES) with variable expression may be responsible. The disorder is associated with explosive vocal tics and grunts, occasionally obscene (see COPROLALIA). The patient may also involuntarily repeat the words or imitate the actions of others (see PALILALIA). HALOPERIDOL, pimozide (an oral antipsychotic drug similar to CHLORPROMAZINE hydrochloride) and clonidine are among drugs that may help to control this distressing, but fortunately rare, disorder.... gilles de la tourette’s syndrome

Sydrome occurs during the invasive stage of schistosomiasis from the time of cercarial penetration of the skin to the time of early egg laying in the veins.... katayama syndrome

Korsakoff’s Syndrome

Its special features are talkativeness with delusions in regard to time and place – the patient, although clear in other matters, imagining that he or she has recently made journeys.... korsakoff’s syndrome

Klinefelter’s Syndrome

The original syndrome described by Klinefelter consisted of GYNAECOMASTIA, testicular ATROPHY and INFERTILITY. Intelligence was unimpaired. Patients have been described who have associated mental defects and striking tallness of stature, but the only constant feature of the syndrome is testicular atrophy with resulting azoospermia and infertility.

The atrophy of the testis is the result of ?brosis, which begins to appear in childhood and progresses until all the seminiferous tubules are replaced by ?brous tissue. Gynaecomastia, mental retardation and eunuchoidism (see EUNUCH; loss of male secondary sexual characteristics – small penis, loss of body hair and a high-pitched voice) may be present. Most patients with Klinefelter’s syndrome have 47 chromosomes instead of the normal 46. The extra chromosome is an X chromosome, so that the sex chromosome constitution is XXY instead of XY. Klinefelter’s syndrome is one of the most common chromosome abnormalities and occurs in 1 in 300 of the male population. Patients with this syndrome show that the Y chromosome is strongly sex-determining: thus, a patient who has an XXY chromosome constitution may have the appearance of a normal male, with infertility the only incapacity, while the loss of a Y chromosome leads to the development of a bodily form which is essentially feminine (see TURNER’S SYNDROME).... klinefelter’s syndrome

Marfan’s Syndrome

An inherited disorder affecting about one person in 50,000 in which the CONNECTIVE TISSUE is abnormal. The result is defects of the heart valves, the arteries arising from the heart, the skeleton and the eyes. The victims are unusually tall and thin with a particular facial appearance (the US President Abraham Lincoln was said to have Marfan’s) and deformities of the chest and spine. They have spider-like ?ngers and toes and their joints and ligaments are weak. Orthopaedic intervention may help, as will drugs to control the heart problems. As affected individuals have a 50 per cent chance of passing on the disease to their children, they should receive genetic counselling.... marfan’s syndrome

Medial Tibial Syndrome

The term applied by athletes to a condition characterised by pain over the inner border of the shin, which occurs in most runners and sometimes in joggers. The syndrome, also known as shin splints, is due to muscular swelling resulting in inadequate blood supply in the muscle: hence the pain. The disorder may be the result of compartment syndrome (build-up of pressure in the muscles), TENDINITIS, muscle or bone in?ammation, or damage to the muscle. It usually disappears within a few weeks, responding to rest and PHYSIOTHERAPY, with or without injections. In some cases, however, it becomes chronic and so severe that it occurs even at rest. If the cause is the compartment syndrome, relief is usually obtained by a simple operation to relieve the pressure in the affected muscles.... medial tibial syndrome

Munchausen’s Syndrome

Munchausen’s syndrome, also known as ‘hospital addiction’ syndrome, is a disorder in which the patient presents repeatedly to hospitals with symptoms and signs (often simulated) suggestive of serious physical illness. More common among men than women, it differs from MALINGERING in that no obvious reward results from the imagined or simulated symptoms. Patients may simulate signs and symptoms in a bizarre way – for instance, by swallowing blood or inserting needles into the chest. Abdominal symptoms are particularly common. They often have a history of multiple hospital admissions and operations, and show extensive pathological lying and lack of personal rapport. Although the cause is unclear, it is thought to be a form of hysterical behaviour in a severely disordered personality. Patients are often masochistic, attention-seeking, and constantly trying to obtain ANALGESICS. Occasionally there may be a degree of treatable DEPRESSION, but on the whole management is very di?cult as patients often abscond from psychiatric treatment.

A variation of the syndrome – Munchausen’s syndrome by proxy, better termed ‘fabricated and induced illness’ – has been identi?ed, in which the persons affected in?ict damage upon others, usually children (or even animals) in their care. Factitious illness refers to simulating symptoms, such as stating that the child has blood in its urine when it is actually the parent’s blood. Induced illness includes such events as injecting dirty water into a baby’s muscles, dropping mild caustic into their eyes, adding salt to a baby’s milk or diluting it 50–50 with water, and so on. Much debate has ensued about the suggestion that some sudden infant deaths are due to smothering rather than natural causes, as a type of induced illness. As a consequence of two successful appeals against conviction for murder in 2004, the UK attorney general ordered a review of all criminal and family court cases in which disputed medical evidence had formed the basis of the decision. Paediatricians are concerned that one result is likely to be an increase in undetected child abuse.... munchausen’s syndrome

Raynauds Either Syndrome Or Disease

The first is less severe, characterized by blanching spasms of blood vessels leading to the hands and feet, initiated by cold, moisture, even emotional stress and low blood sugar. Sort of a finger migraine. After the spasm relaxes, the tissue distal becomes red, hot, even painful. R. Disease is more serious and perhaps deriving from different causes as well. The spasms may not subside, the effected tissues can become purplish, and in extreme cases, gangrenous.... raynauds either syndrome or disease

Recovered Memory Syndrome

See REPRESSED MEMORY THERAPY.... recovered memory syndrome

Reiter’s Syndrome

A condition probably caused by an immunological response to a virus (see IMMUNITY), in which the patient has URETHRITIS, ARTHRITIS and conjunctivitis (see under EYE, DISORDERS OF). The skin may also be affected by horny areas which develop in it. The disorder was ?rst described by a German physician, H. Reiter (1881–1969); it is more common in men than in women, and is the most common cause of arthritis in young men. It usually develops in people who have a genetic predisposition for it: around 80 per cent of sufferers have the HLA B27 tissue type. Treatment is symptomatic with ANALGESICS and NON-STEROIDAL ANTIINFLAMMATORY DRUGS (NSAIDS). (See also REACTIVE ARTHRITIS.)... reiter’s syndrome

Scalded-skin Syndrome

In infants, certain staphylococcal bacteria (see STAPHYLOCOCCUS) can cause an acute toxic illness in which the subject develops sheets of bright ERYTHEMA, accompanied by shedding of layers of outer epidermis. The result is similar to a hot-water scald. The condition responds promptly to appropriate antibiotic therapy. Drug reactions, especially from sulphonamides, may cause a similar syndrome in adults. In drug-induced forms, mucosae are also affected and the disease is often fatal.... scalded-skin syndrome

Reye’s Syndrome

A condition, now rare, which occurs predominantly in young children following a viral infection of the upper respiratory tract or a viral infection such as CHICKENPOX or INFLUENZA.

The cause is not known, but there is evidence that ASPIRIN may also play a part in its causation. Doctors recommend that children should be given PARACETAMOL in place of aspirin. The initial feature is severe, persistent vomiting and fever. This is followed by outbursts of wild behaviour, DELIRIUM and CONVULSIONS terminating in COMA and death, often from liver failure. The MORTALITY rate is around 23 per cent, and 50 per cent of the survivors may have persistent mental or neurological disturbances. The younger the patient, the higher the death rate and the more common the permanent residual effects. Since aspirin has no longer been licensed for use in children and young people the incidence of the condition has fallen dramatcally. Some cases, previously thought to be Reye’s syndrome, have subsequently turned out to have been due to certain inherited metabolic diseases and to be unconnected with aspirin.... reye’s syndrome

Shaken Impact Syndrome

A type of non-accidental head-injury to infants. A study published in 2000 (Lancet, 4 November) suggests that almost 25 out of 100,000 children under a year old sustain brain damage from shaken impact syndrome, even if they do not strike any hard surface. So, of around 685,000 babies in this age-group in Britain, as many as 170 a year may suffer injury from violent shaking. The median age for admission to hospital for the condition in Scotland was 2.2 months in the 18 months from July 1998. A Swedish report has concluded that children at risk from CHILD ABUSE can be identi?ed and the incidence reduced by legislation banning corporal punishment. (See also NON-ACCIDENTAL INJURY (NAI).)... shaken impact syndrome

Sjogren’s Syndrome

A disorder of CONNECTIVE TISSUE, with dryness of the mouth (xerostomia) and dryness of the eye (kerato conjunctivitis sicca) occurring in association with RHEUMATOID ARTHRITIS. It occurs in approximately 10 per cent of patients with the latter condition, but it can occur – and frequently does so – independently of rheumatoid disease. The lack of tears gives rise to symptoms of dryness and grittiness of the eyes; the dry mouth can occasionally be so severe as to cause a DYSPHAGIA. The disease is due to the autoimmune destruction of the SALIVARY GLANDS and the lacrimal glands (see EYE – Lacrimal apparatus). The disorder is usually associated with speci?c HLA antigen (see HLA SYSTEM). Treatment is unsatisfactory and is limited to oral and ocular hygiene as well as the provision of arti?cial tears in the form of cellulose eye drops.... sjogren’s syndrome

Sudden Infant Death Syndrome (sids)

Sudden infant death syndrome, or cot death, refers to the unexpected death – usually during sleep – of an apparently healthy baby. Well over 1,500 such cases are thought to have occurred in the United Kingdom each year until 1992, when government advice was issued about laying babies on their backs. The ?gure was 192 in 2002 and continues to fall. Boys are affected more than girls, and over half of these deaths occur at the age of 2–6 months. More common in lower social classes, the incidence is highest in the winter; most of the infants have been bottle-fed (see also INFANT FEEDING).

Causes These are unknown, with possible multiple aetiology. Prematurity and low birth-weight may play a role. The sleeping position of a baby and an over-warm environment may be major factors, since deaths have fallen sharply since mothers were o?cially advised to place babies on their backs and not to overheat them. Some deaths are probably the result of respiratory infections, usually viral, which may stop breathing in at-risk infants, while others may result from the infant becoming smothered in a soft pillow. Faults in the baby’s central breathing control system (central APNOEA) may be a factor. Other possible factors include poor socioeconomic environment; vitamin E de?ciency; or smoking, drug addiction or anaemia in the mother. Help and advice may be obtained from the Foundation for the Study of Infant Deaths and the Cot Death Society.... sudden infant death syndrome (sids)

Urethral Syndrome

A group of symptoms of unknown cause. It mainly affects women, and occasionally men, with pain and discomfort in the lower abdomen, a frequent urge to urinate and, in women, pain in the area of the VULVA. Investigation rarely results in any abnormal ?ndings. Postmenopausal women (see MENOPAUSE), who are the most common sufferers, may have in?ammation of the vulva due to thinning of the tissues in that area. Treatment is supportive, with the patient being advised to drink a lot of ?uid and maintain a high standard of personal hygiene.... urethral syndrome

Turner’s Syndrome

This occurs in one in 2,500 live female births. It is caused by either the absence of or an abnormality in one of the two X CHROMOSOMES. Classical Turner’s syndrome is a complete deletion of one X so that the karyotype is 45XO. Half of the people with Turner’s syndrome have MOSAICISM with a mixture of Turner cells and normal cells, or other abnormalities of the X chromosome such as partial deletions or a ring X. They are females, both in appearance and sexually; clinical features are variable and include short stature, with ?nal height between 1·295 m and 1·575 m, and ovarian failure. Other clinical features may include a short neck, webbing of the neck, increased carrying angle at the elbow (cubitus valgus), widely spaced nipples, cardiovascular abnormalities (of which the commonest is coarctation of the aorta [about 10 per cent]), morphological abnormalities of the kidneys (including horseshoe kidney and abnormalities of the pelviureteric tracts), recurrent otitis media (see under EAR, DISEASES OF), squints, increased incidence of pigmented naevi (see NAEVUS), hypothyroidism (see under THYROID, DISEASES OF) and DIABETES MELLITUS. Intelligence is across the normal range, although there are speci?c learning defects which are related to hand-eye coordination and spatial awareness.

Patients with Turner’s syndrome may require therapeutic help throughout their life. In early childhood this may revolve around surgical correction of cardiovascular disease and treatment to improve growth. Usually, PUBERTY will need to be induced with oestrogen therapy (see OESTROGENS). In adult life, problems of oestrogen therapy, prevention of osteoporosis (see under BONE, DISORDERS OF), assessment and treatment of HYPERTENSION and assisted fertility predominate.

Building Sickness Syndrome

Work-related lethargy coming on in the afternoon may be the result of this syndrome. Air-conditioned buildings promote symptoms not encountered in naturally ventilated offices, shops, etc.

Symptoms: dry throat, eye irritation, headache, fatigue, wheezy chest and flu-like colds may be a product of modern ventilating systems. The headache may come on in the afternoon and improve on leaving work. Humidifier fever. Passive inhalation of cigarette smoke a factor.

Alternatives. Treatment. Ginseng, Iceland Moss, Irish Moss, German Chamomile tea. ... building sickness syndrome

Commuter’s Syndrome

A range of complaints blamed on the effects of commuting to and from work.

Symptoms: headaches, palpitations, skin complaints, sleeplessness, digestive disorders, chest pains and excessive perspiration. These may be due to exposure to unsatisfactory levels of bacterial and chemical pollution. Where symptoms are not due to any underlying condition, Ginseng, Gota Kola and Chaparral may usually be relied on.

Preparations: teas, tablets, liquid extracts. Professional woman’s fatigue may be dispelled by German Chamomile tea. ... commuter’s syndrome

Eosinophilic Myalgia Syndrome (ems)

An increase in the number of eosinophils in the blood. May occur in a number of allergies, infections, and is sometimes responsible for leukaemia. Among other causes, food supplement tryptophan has been linked. See entry.

Symptoms. Stiffness and severe muscle pain.

Treatment. Formula. Echinacea 2; Burdock 1; Yarrow 1; Poke root quarter. Dose: Liquid Extracts: 1-2 teaspoons. Tinctures: 2-3 teaspoons. Powders: 750mg (three 00 capsules or half a teaspoon). Thrice daily. ... eosinophilic myalgia syndrome (ems)

Carpal Tunnel Syndrome (cts)

Compression of the median nerve between the transverse carpal ligament and the carpal bone. May cause damage to the sensory and motor nerves and manifest as teno-synovitis or ganglion. Affects chiefly middle-aged women.

Symptoms. Numbness or tingling in first three fingers which feel ‘clumsy’. Worse at night. Muscle wasting of palm of the hand.

Diagnostic sign: the ‘flick’ sign – shaking or ‘flicking’ of the wrist when pain is worse and which is believed to mechanically untether the nerve and promote return of venous blood. (J. Neural Neurosurgery and Psychiatry, 1984, 47, 873)

Differential diagnosis: compression of seventh cervical spinal nerve root (osteopathic lesion) has tingling of the hands when standing or from exaggerated neck movements.

Treatment. Reduction of spasm with peripheral relaxants (antispasmodics). Also: local injection of corticosteroid or surgical division of the transverse carpal ligament.

In chronic cases, irreversible brain damage may already have occurred. (See also psychosis.)... brain syndrome, organic

Floppy Valve Syndrome

See mitral valve prolapse.... floppy valve syndrome

Guillain–barré Syndrome

A rare condition affecting the peripheral nerves (see peripheral nervous system) that causes weakness, usually in the limbs. The cause is believed to be an allergic reaction to an infection, usually viral; the nerves are damaged by antibodies produced by the body to eliminate the infection. In most cases, the disease develops 2 or 3 weeks after the onset of infection. Weakness, often accompanied by numbness and tingling, usually starts in the legs and spreads to the arms. The weakness may become progressively worse, resulting in paralysis. The muscles of the face and those controlling speech, swallowing, and breathing may also be affected.

Diagnosis of Guillain–Barré syndrome is confirmed by electrical tests to measure how fast nerve impulses are being conducted, or by a lumbar puncture. Most people recover fully with only supportive treatment. However, in severe cases, treatment with plasmapheresis or immunoglobulin may be given. Mechanical ventilation may be needed to aid breathing if the respiratory muscles and diaphragm are severely affected. Some people are left with permanent weakness in affected areas and/or suffer from further attacks of the disease.... guillain–barré syndrome

Haemolytic–uraemic Syndrome

A rare disease in which red blood cells are destroyed prematurely and the kidneys are damaged, causing acute kidney failure. Thrombocytopenia can also occur. Haemolytic–uraemic syndrome most commonly affects young children and may be triggered by a serious bacterial or viral infection. Symptoms include weakness, lethargy, and a reduction in the volume of urine. Seizures may occur. Blood and urine tests can determine the degree of kidney damage. Dialysis may be needed until the kidneys have recovered. Most patients recover normal renal function.... haemolytic–uraemic syndrome

Hand–arm Vibration Syndrome

Pain and numbness in the hand and arm due to prolonged use of vibrating tools. Symptoms often also include blue or white coloration of the fingers and a tingling sensation in affected areas. Hand–arm vibration syndrome tends to develop slowly over years and is the result of repeated damage to blood vessels and nerves. Exposure to cold tends to aggravate the condition. There is no specific treatment, but avoiding vibrating tools is essential to prevent the disease progressing. In some cases, calcium channel blockers may help relieve some symptoms.... hand–arm vibration syndrome

Hypoplastic Left-heart Syndrome

A very serious form of congenital heart disease (see heart disease, congenital). The baby is born with a poorly formed left ventricle, often associated with other heart defects. The aorta is malformed and blood can reach it only via a duct (the ductus arteriosus) that links the aorta to the pulmonary artery.

At birth, the baby may seem healthy. However, within a day or 2 the ductus arteriosus naturally closes off and the baby collapses, becoming pale and breathless. In most cases, hypoplastic left-heart syndrome cannot be treated surgically, and most affected babies die within a week. A few infants have been treated with heart transplants.... hypoplastic left-heart syndrome

The cause of shoulder–hand syndrome is unknown, but it may occur as a complication of myocardial infarction, stroke, herpes zoster, or shoulder injury. Recovery usually occurs in about 2 years. This period may be shortened by physiotherapy and corticosteroid drugs. In rare cases, a cervical sympathectomy is performed.... shoulder–hand syndrome

Shy–drager Syndrome

A rare degenerative disorder of unknown cause that progressively damages the autonomic nervous system. It begins gradually at age 60–70 and is more common in men. Symptoms include dizziness and fainting due to postural hypotension, urinary incontinence, impotence, reduced ability to sweat, and parkinsonism. The condition eventually leads to disability, and sometimes premature death. There is no cure or means of slowing degeneration, but many symptoms are relieved by drugs.... shy–drager syndrome

Sick Sinus Syndrome

Abnormal function of the heart’s sinoatrial node that leads to episodes of bradycardia (slow heart-rate), alternating bradycardia and tachycardia (fast heart-rate), or very short episodes of cardiac arrest.

The cause is usually coronary artery disease, but may be a cardiomyopathy.

Symptoms may include lightheadedness, fainting, and palpitations.

The diagnosis is confirmed by a 24-hour ECG recording.

Treatment is usually by antiarrhythmic drugs and the fitting of an artificial pacemaker.... sick sinus syndrome

Sturge–weber Syndrome

A rare, congenital condition that affects the skin and the brain. Characteristically, a large purple birthmark (port wine stain) extends over one side of the face, including the eye. Malformation of cerebral blood vessels may cause weakness on one side of the body, progressive mental handicap, and epilepsy. Glaucoma may develop in the affected eye, leading to loss of vision.

Seizures can usually be controlled with anticonvulsant drugs.

In severe cases, brain surgery may be necessary.... sturge–weber syndrome

Supraspinatus Syndrome

See painful arc syndrome.... supraspinatus syndrome

Thoracic Outlet Syndrome

A condition in which pressure on the brachial plexus causes pain in the arms and shoulders, pins-and-needles sensation in the fingers, and weakness of grip and other hand movements. Severe symptoms are usually caused by a cervical rib. Thoracic outlet syndrome may also be caused by drooping of the shoulders, an enlarged scalenus muscle in the neck, or a tumour.The condition is made worse by lifting and carrying heavy loads or by increases in body weight.

Treatment of thoracic outlet syndrome usually consists of exercises to improve posture, sometimes together with nonsteroidal anti-inflammatory drugs and muscle-relaxant drugs. Severe cases may be treated by surgical removal of the 1st rib.... thoracic outlet syndrome

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

Acquired Immune Deficiency Syndrome

Wernicke–korsakoff Syndrome

An uncommon brain disorder almost always related to malnutrition occurring in chronic alcohol dependence, but occasionally due to that which occurs in other conditions, such as cancer. Wernicke–Korsakoff syndrome is caused by deficiency of thiamine (see vitamin B complex), which affects the brain and nervous system.The disease consists of 2 stages: Wernicke’s encephalopathy and Korsakoff’s psychosis. Wernicke’s encephalopathy usually develops suddenly and produces nystagmus (abnormal, jerky eye movements), ataxia (difficulty in coordinating body movements), slowness, and confusion. Sufferers usually have signs of neuropathy, such as loss of sensation, pins-and-needles, or impaired reflexes. The level of consciousness falls progressively and may lead to coma and death unless treated. The condition is a medical emergency. Treatment with high doses of intravenous thiamine often reverses most of the symptoms, sometimes within a few hours.

Korsakoff’s psychosis may follow Wernicke’s encephalopathy if treatment is not begun promptly enough. Symptoms consist of severe amnesia, apathy, and disorientation. Korsakoff’s psychosis is usually irreversible.... wernicke–korsakoff syndrome

Withdrawal Syndrome

Unpleasant mental and physical symptoms experienced when a person stops using a drug on which he or she is dependent (see drug dependence). Withdrawal syndrome most commonly occurs in those with alcohol dependence or dependence on opioids, in smokers, and in people addicted to tranquillizers, amfetamines, cocaine, marijuana, and caffeine.

Alcohol withdrawal symptoms start 6–8 hours after cessation of intake and may last up to 7 days. They include trembling of the hands, nausea, vomiting, sweating, cramps, anxiety, and, sometimes, seizures. (See also confusion, delirium tremens, and hallucinations.)

Opioid withdrawal symptoms start after 8–12 hours and may last for 7–10 days. Symptoms include restlessness, sweating, runny eyes and nose, yawning, diarrhoea, vomiting, abdominal cramps, dilated pupils, loss of appetite, irritability, weakness, tremor, and depression.

Withdrawal symptoms from barbiturate drugs and meprobamate start after 12–24 hours, beginning with tremor, anxiety, restlessness, and weakness, sometimes followed by delirium, hallucinations, and, occasionally, seizures. A period of prolonged sleep occurs 3–8 days after onset. Withdrawal from benzodiazepine drugs may begin much more slowly and can be life-threatening.

Withdrawal symptoms from nicotine develop gradually over 24–48 hours and include irritability, concentration problems, frustration, headaches, and anxiety. Discontinuation of cocaine or amfetamines results in extreme tiredness, lethargy, and dizziness. Cocaine withdrawal may also lead to tremor, severe depression, and sweating.

Withdrawal symptoms from marijuana include tremor, nausea, vomiting, diarrhoea, sweating, irritability, and sleep problems. Caffeine withdrawal may lead to tiredness, headaches, and irritability.

Severe withdrawal syndromes require medical treatment.

Symptoms may be suppressed by giving the patient small quantities of the drug he or she had been taking.

More commonly, a substitute drug is given, such as methadone for opioid drugs or diazepam for alcohol.

The dose of the drug is then gradually reduced.... withdrawal syndrome

Adie’s Syndrome

(Holmes-Adie syndrome) an abnormality of the pupils of the eyes, often affecting only one eye. The affected pupil is dilated and reacts slowly to light; the response on convergence *accommodation of the eyes is also slow (see tonic pupil). Tendon reflexes may be absent.

(painful bruising syndrome, psychogenic purpura) a rare disorder, characterized by unexplained, recurrent, and painful bruising, typically arising after physical and/or psycho-emotional stress. Classically, ecchymoses spontaneously appear and are associated with a prodrome of warmth and pain at the sites. The condition, which is seen primarily in young to middle-aged women, is induced by trauma and associated with *personality disorders. Research into the syndrome is sparse but recent publications suggest that only a minority of patients experience a serious reduction in their quality of life, that the condition seems to be dermal rather than systematic in most patients, and that it seems to be associated with ongoing stress. [L. K. Diamond (1902–1999), US paediatrician; F. H. Gardner (1919–2013), US haematologist]... gardner–diamond syndrome

Hepatorenal Syndrome

impairment of renal function, which can occur in acute or chronic liver disease. The condition is associated with intrarenal vasoconstriction and extrarenal vasodilation and hypotension, and the kidney disease is functional rather than structural in nature. There are two common clinical presentations. An acute form (type 1) is characterized by rapid spontaneous deterioration in renal function against a background of acute liver failure, acute alcoholic hepatitis, or acute decompensation of chronic cirrhotic liver disease. A chronic form (type 2) is characterized by insidious onset and slowly progressive deterioration in renal function. This is most often observed in patients with decompensated cirrhosis and portal hypertension. The prognosis of hepatorenal syndrome is extremely poor, and the best hope of survival is usually with liver transplantation.... hepatorenal syndrome

Liddle’s Syndrome

a rare autosomal *dominant condition characterized by hypertension associated with hypokalaemia, metabolic alkalosis, and low levels of plasma *renin and *aldosterone. The hypertension often starts in infancy and is due to excess resorption of sodium and excretion of potassium by the renal tubules. The syndrome is caused by a single genetic mutation on chromosome 16, which results in dysregulation of a sodium channel in the distal convoluted tubule. Treatment is with a low salt diet and a potassium-sparing diuretic that directly blocks the sodium channel, such as amiloride or triamterene. [G. G. Liddle (1921–89), US endocrinologist]... liddle’s syndrome

Refeeding Syndrome

a potentially fatal condition that may affect severely malnourished patients in response to the reintroduction of a protein- and calorie-rich diet. It is thought to be due to severe fluid and *electrolyte shifts (especially low phosphate, magnesium, and potassium levels in the blood) and related metabolic complications (e.g. raised levels of insulin in the blood).

Treatment involves surgery to repair the bony defect.... superior canal dehiscence syndrome

Staphylococcal Scalded Skin Syndrome

(Ritter’s disease) a potentially serious condition of young infants (and occasionally seen in adults) in which the skin becomes reddened and tender and then peels off, giving the appearance of a scald. The area of skin loss may be quite extensive and is usually centred on the armpits and groin. The underlying cause is an infection by certain bacteria of the genus *Staphylococcus. It is contagious and may occur in clusters. Treatment is by antibiotics (usually intravenous), but careful nursing is essential to prevent skin damage. Admission to hospital is mandatory for small children.... staphylococcal scalded skin syndrome

Syndrome Of Inappropriate Secretion Of Antidiuretic Hormone

(SIADH) a condition of inappropriately high plasma levels of ADH (see vasopressin) with associated water retention, dilutional *hyponatraemia, and the production of highly concentrated urine. Renal, adrenal, thyroid, and hepatic function are normal, as is the volume of circulating blood (euvolaemia). It is caused by a variety of pathological conditions, usually intrathoracic and intracerebral, and also by a number of drugs, including antidepressants, chemotherapy agents, and some of the older antidiabetic agents. The treatment involves fluid restriction, treatment (or removal) of the underlying cause (or drug), and, in severe cases, administration of *demeclocycline to reduce the effects of ADH on the kidney. Very rarely, hypertonic saline is given.... syndrome of inappropriate secretion of antidiuretic hormone

Treacher Collins Syndrome

(Treacher Collins deformity) a hereditary disorder of facial development. It is characterized by underdevelopment of the jaw and zygomatic (cheek) bones and the precursors of the ear fail to develop, which results in a variety of ear and facial malformations. The ear abnormality may cause deafness. [E. Treacher Collins (1862–1919), British ophthalmologist]... treacher collins syndrome

Twin-to-twin Transfusion Syndrome

(TTTS) a condition in which communicating vessels in the shared placenta of monochorionic twins (see chorionicity) divert blood to one fetus (the recipient) from the other (the donor), resulting in one fetus with increased blood volume and one anaemic fetus. It complicates 15% of monochorionic twin pregnancies, and a system of ultrasound staging has been developed to assess the severity of the syndrome. TTTS is associated with a high perinatal mortality rate. There is significant morbidity and poor neurodevelopmental outcome in surviving infants due to complications of the disease itself and the high preterm birth rate that invariably accompanies this condition. A range of treatments, including *amnioreduction, *septostomy, and laser ablation of the communicating vessels, have led to an improvement in overall perinatal survival rates.... twin-to-twin transfusion syndrome

Werner’s Syndrome

a rare genetic disorder resulting in premature ageing that starts at adolescence. Growth may be retarded and affected individuals may suffer from a thin skin, arterial disease, leg ulcers, and diabetes. Treatment is limited to the management of complications, such as diabetes. The gene responsible codes for an enzyme involved in the mechanisms of DNA replication and repair, which in affected individuals is defective. [C. W. O. Werner (1879–1936), German physician]... werner’s syndrome

Williams Syndrome

a hereditary condition, caused by a defect (a *deletion) in chromosome 7, marked by a characteristic ‘elfin’ facial appearance (including large eyes, a wide mouth, and small chin), *hypercalcaemia, short stature, learning disabilities, and *aortic stenosis. Most affected children are highly sociable and have unusual conversational ability, using a rich and complex vocabulary. The condition can be diagnosed prenatally. [J. C. P. Williams (20th century), British physician]... williams syndrome

Wiskott–aldrich Syndrome

a rare *sex-linked recessive disorder characterized by eczema, *thrombocytopenia, and deficiency in the immune response (*immunodeficiency). It is caused by a decrease in the amount of Wiskott–Aldrich syndrome protein (WASP: a protein occurring in lymphocytes, platelets, and other cells) due to a mutation in the WASP gene.... wiskott–aldrich syndrome

Wolff–parkinson–white Syndrome

a congenital abnormality of heart conduction caused by the presence of an *accessory pathway of conduction between the atria and ventricles. It results in premature excitation of one ventricle and is characterized by an abnormal wave (delta wave) at the start of the QRS complex on the electrocardiogram. The accessory pathway predisposes the patient to episodes of fast heart rate due to the rapid self-sustaining circulation of an electrical impulse from the atria to the ventricles and back again (*atrioventricular reciprocating tachycardia). Emergency treatment is in the form of drugs that temporarily block the re-entry circuit. Permanent destruction of the accessory pathway by *radiofrequency ablation is usually curative. [L. Wolff; Sir J. Parkinson (1885–1976), British physician; P. D. White (1886–1973), US cardiologist]... wolff–parkinson–white syndrome
