– the hormone which provokes the adrenal cortex into action.
Symptoms The clinical symptoms appear slowly and depend upon the severity of the underlying disease process. The patient usually complains of appetite and weight loss, nausea, weakness and fatigue. The skin becomes pigmented due to the increased production of ACTH. Faintness, especially on standing, is due to postural HYPOTENSION secondary to aldosterone de?ciency. Women lose their axillary hair and both sexes are liable to develop mental symptoms such as DEPRESSION. Acute episodes – Addisonian crises – may occur, brought on by infection, injury or other stressful events; they are caused by a fall in aldosterone levels, leading to abnormal loss of sodium and water via the kidneys, dehydration, low blood pressure and confusion. Patients may develop increased tanning of the skin from extra pigmentation, with black or blue discoloration of the skin, lips, mouth, rectum and vagina occurring. ANOREXIA, nausea and vomiting are common and the sufferer may feel cold.
Diagnosis This depends on demonstrating impaired serum levels of cortisol and inability of these levels to rise after an injection of ACTH.
Treatment consists in replacement of the de?cient hormones. HYDROCORTISONE tablets are commonly used; some patients also require the salt-retaining hormone, ?udrocortisone. Treatment enables them to lead a completely normal life and to enjoy a normal life expectancy. Before surgery, or if the patient is pregnant and unable to take tablets, injectable hydrocortisone may be needed. Rarely, treated patients may have a crisis, perhaps because they have not been taking their medication or have been vomiting it. Emergency resuscitation is needed with ?uids, salt and sugar. Because of this, all patients should carry a card detailing their condition and necessary management. Treatment of any complicating infections such as tuberculosis is essential. Sometimes DIABETES MELLITUS coexists with Addison’s disease and must be treated.
Secondary adrenal insu?ciency may occur in panhypopituitarism (see PITUITARY GLAND), in patients treated with CORTICOSTEROIDS or after such patients have stopped treatment.... Medical Dictionary
Both HIV-1 and HIV-2 are predominantly sexually transmitted and both are associated with secondary opportunistic infections. However, HIV-2 seems to result in slower damage to the immune system. HIV-1 is known to mutate rapidly and has given rise to other subtypes.
HIV is thought to have occurred in humans in the 1950s, but whether or not it infected humans from another primate species is uncertain. It became widespread in the 1970s but its latency in causing symptoms meant that the epidemic was not noticed until the following decade. Although it is a sexually transmitted disease, it can also be transmitted by intravenous drug use (through sharing an infected needle), blood transfusions with infected blood (hence the importance of e?ective national blood-screening programmes), organ donation, and occupationally (see health-care workers, below). Babies born of HIV-positive mothers can be infected before or during birth, or through breast feeding.
Although HIV is most likely to occur in blood, semen or vaginal ?uid, it has been found in saliva and tears (but not sweat); however, there is no evidence that the virus can be transmitted from these two body ?uids. There is also no evidence that HIV can be transmitted by biting insects (such as mosquitoes). HIV does not survive well in the environment and is rapidly destroyed through drying.
Prevalence At the end of 2003 an estimated 42 million people globally were infected with HIV – up from 40 million two years earlier. About one-third of those with HIV/AIDS are aged 15–24 and most are unaware that they are carrying the virus. During 2003 it is estimated that 5 million adults and children worldwide were newly infected with HIV, and that 3 million adults and children died. In Africa in 2003,
3.4 million people were newly infected and 2.3 million died, with more than 28 million carrying the virus. HIV/AIDS was the leading cause of death in sub-Saharan Africa where over half of the infections were in women and 90 per cent of cases resulted from heterosexual sex. In some southern African countries, one in three pregnant women had HIV.
In Asia and the Paci?c there were 1.2 million new infections and 435,000 deaths. The area with the fastest-growing epidemic is Eastern Europe, especially the Russian Federation where in 2002 around a million people had HIV and there were an estimated 250,000 new infections, with intravenous drug use a key contributor to this ?gure. Seventy-?ve per cent of cases occurred in men, with male-to-male sexual transmission an important cause of infection, though heterosexual activity is a rising cause of infection.
At the end of 2002 the UK had an estimated 55,900 HIV-infected adults aged between 15 and 59. More than 3,600 individuals were newly diagnosed with the infection in 2000, the highest annual ?gure since the epidemic started
– in 1998 the ?gure was 2,817 and in 1999 just over 3,000 (Department of Health and Communicable Disease Surveillance Centre). The incidence of AIDS in the UK has declined sharply since the introduction of highly active antiretroviral therapy (HAART) and HIV-related deaths have also fallen: in 2002 there were 777 reported new AIDS cases and 395 deaths, compared with 1,769 and 1,719 respectively in 1995. (Sources: UNAIDS and WHO, AIDS Epidemic Update, December 2001; Public Health Laboratory Services AIDS and STD Centre Communicable Disease Surveillance and Scottish Centre for Infection and Environmental Health, Quarterly Surveillance Tables.)
Poverty is strongly linked to the spread of AIDS, for various reasons including lack of health education; lack of e?ective public-health awareness; women having little control over sexual behaviour and contraception; and, by comparison with the developed world, little or no access to antiretroviral drugs.
Pathogenesis The cellular target of HIV infection is a subset of white blood cells called T-lymphocytes (see LYMPHOCYTE) which carry the CD4 surface receptor. These so-called ‘helper T-cells’ are vital to the function of cell-mediated immunity. Infection of these cells leads to their destruction (HIV replicates at an enormous rate – 109) and over the course of several years the body is unable to generate suf?cient new cells to keep pace. This leads to progressive destruction of the body’s immune capabilities, evidenced clinically by the development of opportunistic infection and unusual tumours.
Monitoring of clinical progression It is possible to measure the number of viral particles present in the plasma. This gives an accurate guide to the likely progression rate, which will be slow in those individuals with fewer than 10,000 particles per ml of plasma but progressively more rapid above this ?gure. The main clinical monitoring of the immune system is through the numbers of CD4 lymphocytes in the blood. The normal count is around 850 cells per ml and, without treatment, eventual progression to AIDS is likely in those individuals whose CD4 count falls below 500 per ml. Opportunistic infections occur most frequently when the count falls below 200 per ml: most such infections are treatable, and death is only likely when the CD4 count falls below 50 cells per ml when infection is developed with organisms that are di?cult to treat because of their low intrinsic virulence.
Simple, cheap and highly accurate tests are available to detect HIV antibodies in the serum. These normally occur within three months of infection and remain the cornerstone of the diagnosis.
Clinical features Most infected individuals have a viral illness some three weeks after contact with HIV. The clinical features are often non-speci?c and remain undiagnosed but include a ?ne red rash, large lymph nodes, an in?uenza-like illness, cerebral involvement and sometimes the development of opportunistic infections. The antibody test may be negative at this stage but there are usually high levels of virus particles in the blood. The antibody test is virtually always positive within three months of infection. HIV infection is often subsequently asymptomatic for a period of ten years or more, although in most patients progressive immune destruction is occurring during this time and a variety of minor opportunistic infections such as HERPES ZOSTER or oral thrush (see CANDIDA) do occur. In addition, generalised LYMPHADENOPATHY is present in a third of patients and some suffer from severe malaise, weight loss, night sweats, mild fever, ANAEMIA or easy bruising due to THROMBOCYTOPENIA.
The presentation of opportunistic infection is highly variable but usually involves either the CENTRAL NERVOUS SYSTEM, the gastrointestinal tract or the LUNGS. Patients may present with a sudden onset of a neurological de?cit or EPILEPSY due to a sudden onset of a STROKE-like syndrome, or epilepsy due to a space-occupying lesion in the brain – most commonly TOXOPLASMOSIS. In late disease, HIV infection of the central nervous system itself may produce progressive memory loss, impaired concentration and mental slowness called AIDS DEMENTIA. A wide variety of opportunistic PROTOZOA or viruses produces DYSPHAGIA, DIARRHOEA and wasting. In the respiratory system the commonest opportunistic infection associated with AIDS, pneumonia, produces severe shortness of breath and sometimes CYANOSIS, usually with a striking lack of clinical signs in the chest.
In very late HIV infection, when the CD4 count has fallen below 50 cells per ml, infection with CYTOMEGALOVIRUS may produce progressive retinal necrosis (see EYE, DISORDERS OF) which will lead to blindness if untreated, as well as a variety of gastrointestinal symptoms. At this stage, infection with atypical mycobacteria is also common, producing severe anaemia, wasting and fevers. The commonest tumour associated with HIV is Kaposi’s sarcoma which produces purplish skin lesions. This and nonHodgkin’s lymphoma (see LYMPHOMA), which is a hundred times more frequent among HIV-positive individuals than in the general population, are likely to be associated with or caused by opportunistic viral infections.
Prevention There is, as yet, no vaccine to prevent HIV infection. Vaccine development has been hampered
by the large number of new HIV strains generated through frequent mutation and recombination.
because HIV can be transmitted as free virus and in infected cells.
because HIV infects helper T-cells – the very cells involved in the immune response. There are, however, numerous research pro
grammes underway to develop vaccines that are either prophylactic or therapeutic. Vaccine-development strategies have included: recombinant-vector vaccines, in which a live bacterium or virus is genetically modi?ed to carry one or more of the HIV genes; subunit vaccines, consisting of small regions of the HIV genome designed to induce an immune response without infection; modi?ed live HIV, which has had its disease-promoting genes removed; and DNA vaccines – small loops of DNA (plasmids) containing viral genes – that make the host cells produce non-infectious viral proteins which, in turn, trigger an immune response and prime the immune system against future infection with real virus.
In the absence of an e?ective vaccine, preventing exposure remains the chief strategy in reducing the spread of HIV. Used properly, condoms are an extremely e?ective method of preventing exposure to HIV during sexual intercourse and remain the most important public-health approach to countering the further acceleration of the AIDS epidemic. The spermicide nonoxynol-9, which is often included with condoms, is known to kill HIV in vitro; however, its e?ectiveness in preventing HIV infection during intercourse is not known.
Public-health strategies must be focused on avoiding high-risk behaviour and, particularly in developing countries, empowering women to have more control over their lives, both economically and socially. In many of the poorer regions of the world, women are economically dependent on men and refusing sex, or insisting on condom use, even when they know their partners are HIV positive, is not a straightforward option. Poverty also forces many women into the sex industry where they are at greater risk of infection.
Cultural problems in gaining acceptance for universal condom-use by men in some developing countries suggests that other preventive strategies should also be considered. Microbicides used as vaginal sprays or ‘chemical condoms’ have the potential to give women more direct control over their exposure risk, and research is underway to develop suitable products.
Epidemiological studies suggest that male circumcision may o?er some protection against HIV infection, although more research is needed before this can be an established public-health strategy. Globally, about 70 per cent of infected men have acquired the virus through unprotected vaginal sex; in these men, infection is likely to have occurred through the penis with the mucosal epithelia of the inner surface of the foreskin and the frenulum considered the most likely sites for infection. It is suggested that in circumcised men, the glans may become keratinised and thus less likely to facilitate infection. Circumcision may also reduce the risk of lesions caused by other sexually transmitted disease.
Treatment AIDS/HIV treatment can be categorised as speci?c therapies for the individual opportunistic infections – which ultimately cause death – and highly active antiretroviral therapy (HAART) designed to reduce viral load and replication. HAART is also the most e?ective way of preventing opportunistic infections, and has had a signi?cant impact in delaying the onset of AIDS in HIV-positive individuals in developed countries.
Four classes of drugs are currently in use. Nucleoside analogues, including ZIDOVUDINE and DIDANOSINE, interfere with the activity of the unique enzyme of the retrovirus reverse transcriptase which is essential for replication. Nucleotide analogues, such as tenofovir, act in the same way but require no intracellular activation. Non-nucleoside reverse transcriptase inhibitors, such as nevirapine and EFAVIRENZ, act by a di?erent mechanism on the same enzyme. The most potent single agents against HIV are the protease inhibitors, such as lopinavir, which render a unique viral enzyme ineffective. These drugs are used in a variety of combinations in an attempt to reduce the plasma HIV viral load to below detectable limits, which is achieved in approximately 90 per cent of patients who have not previously received therapy. This usually also produces a profound rise in CD4 count. It is likely, however, that such treatments need to be lifelong – and since they are associated with toxicities, long-term adherence is di?cult. Thus the optimum time for treatment intervention remains controversial, with some clinicians believing that this should be governed by the viral load rising above 10,000 copies, and others that it should primarily be designed to prevent the development of opportunistic infections – thus, that initiation of therapy should be guided more by the CD4 count.
It should be noted that the drug regimens have been devised for infection with HIV-1; it is not known how e?ective they are at treating infection with HIV-2.
HIV and pregnancy An HIV-positive woman can transmit the virus to her fetus, with the risk of infection being particularly high during parturition; however, the risk of perinatal HIV transmission can be reduced by antiviral drug therapy. In the UK, HIV testing is available to all women as part of antenatal care. The bene?ts of antenatal HIV testing in countries where antiviral drugs are not available are questionable. An HIV-positive woman might be advised not to breast feed because of the risks of transmitting HIV via breastmilk, but there may be a greater risk associated with not breast feeding at all. Babies in many poor communities are thought to be at high risk of infectious diseases and malnutrition if they are not breast fed and may thus be at greater overall risk of death during infancy.
Counselling Con?dential counselling is an essential part of AIDS management, both in terms of supporting the psychological wellbeing of the individual and in dealing with issues such as family relations, sexual partners and implications for employment (e.g. for health-care workers). Counsellors must be particularly sensitive to culture and lifestyle issues. Counselling is essential both before an HIV test is taken and when the results are revealed.
Health-care workers Health-care workers may be at risk of occupational exposure to HIV, either through undertaking invasive procedures or through accidental exposure to infected blood from a contaminated needle (needlestick injury). Needlestick injuries are frequent in health care – as many as 600,000 to 800,000 are thought to occur annually in the United States. Transmission is much more likely where the worker has been exposed to HIV through a needlestick injury or deep cut with a contaminated instrument than through exposure of mucous membranes to contaminated blood or body ?uids. However, even where exposure occurs through a needlestick injury, the risk of seroconversion is much lower than with a similar exposure to hepatitis C or hepatitis B. A percutaneous exposure to HIV-infected blood in a health-care setting is thought to carry a risk of about one infection per 300 injuries (one in 1,000 for mucous-membrane exposure), compared with one in 30 for hepatitis C, and one in three for hepatitis B (when the source patient is e-antigen positive).
In the event of an injury, health-care workers are advised to report the incident immediately where, depending on a risk assessment, they may be o?ered post-exposure prophylaxis (PEP). They should also wash the contaminated area with soap and water (but without scrubbing) and, if appropriate, encourage bleeding at the site of injury. PEP, using a combination of antiretroviral drugs (in a similar regimen to HAART – see above), is thought to greatly reduce the chances of seroconversion; it should be commenced as soon as possible, preferably within one or two hours of the injury. Although PEP is available, safe systems of work are considered to o?er the greatest protection. Double-gloving (latex gloves remove much of the blood from the surface of the needle during a needlestick), correct use of sharps containers (for used needles and instruments), avoiding the resheathing of used needles, reduction in the number of blood samples taken from a patient, safer-needle devices (such as needles that self-blunt after use) and needleless drug administration are all thought to reduce the risk of exposure to HIV and other blood-borne viruses. Although there have been numerous cases of health-care workers developing HIV through occupational exposure, there is little evidence of health-care workers passing HIV to their patients through normal medical procedures....

Alcohol depresses the central nervous system and disturbs both mental and physical functioning. Even small doses of alcohol will slow a person’s re?exes and concentration; potentially dangerous effects when, for example, driving or operating machinery. Drunkenness causes slurred speech, muddled thinking, amnesia (memory loss), drowsiness, erectile IMPOTENCE, poor coordination and dulled reactions – thereby making driving or operating machinery especially dangerous. Disinhibition may lead to extreme euphoria, irritability, misery or aggression, depending on the underlying mood at the start of drinking. Severe intoxication may lead to COMA and respiratory failure.
Persistent alcohol misuse leads to physical, mental, social and occupational problems, as well as to a risk of DEPENDENCE (see also ALCOHOL DEPENDENCE). Misuse may follow several patterns: regular but controlled heavy intake, ‘binge’ drinking, and dependence (alcoholism). The ?rst pattern usually leads to mainly physical problems such as gastritis, peptic ulcer, liver disease, heart disease and impotence. The second is most common among young men and usually leads to mainly social and occupational problems – getting into ?ghts, jeopardising personal relationships, overspending on alcohol at weekends, and missing days o? work because of hangovers. The third pattern – alcohol dependence – is the most serious, and can severely disrupt health and social stability.
Many researchers consider alcohol dependence to be an illness that runs in families, with a genetic component which is probably passed on as a vulnerable personality. But it is hard to disentangle genetic, environmental and social factors in such families. In the UK there are estimated to be around a million people suffering from alcohol dependence and a similar number who have di?culty controlling their consumption (together about 1:30 of the population).
Alcohol causes tolerance and both physical and psychological dependence (see DEPENDENCE for de?nitions). Dependent drinkers classically drink early in the morning to relieve overnight withdrawal symptoms. These symptoms include anxiety, restlessness, nausea and vomiting, and tremor. Sudden withdrawal from regular heavy drinking can lead to life-threatening delirium tremens (DTs), with severe tremor, hallucinations (often visual – seeing spiders and monsters, rather than the pink elephants of romantic myth), and CONVULSIONS. This must be treated urgently with sedative drugs, preferably by intravenous drip. Similar symptoms, plus severe INCOORDINATION and double-vision, can occur in WERNICKE’S ENCEPHALOPATHY, a serious neurological condition due to lack of the B vitamin thiamine (whose absorption from the stomach is markedly reduced by alcohol). If not treated urgently with injections of thiamine and other vitamins, this can lead to an irreversible form of brain damage called Korsako?’s psychosis, with severe amnesia. Finally, prolonged alcohol misuse can cause a form of dementia.
In addition to these severe neurological disorders, the wide range of life-threatening problems caused by heavy drinking includes HEPATITIS, liver CIRRHOSIS, pancreatitis (see PANCREAS, DISEASES OF), gastrointestinal haemorrhage, suicide and FETAL ALCOHOL SYNDROME; pregnant women should not drink alcohol as this syndrome may occur with more than a glass of wine or half-pint of beer a day. The social effects of alcohol misuse – such as marital breakdown, family violence and severe debt – can be equally devastating.
Treatment of alcohol-related problems is only moderately successful. First, many of the physical problems are treated in the short term by doctors who fail to spot, or never ask about, heavy drinking. Second, attempts at treating alcohol dependence by detoxi?cation or ‘drying out’ (substituting a tranquillising drug for alcohol and withdrawing it gradually over about a week) are not always followed-up by adequate support at home, so that drinking starts again. Home support by community alcohol teams comprising doctors, nurses, social workers and, when appropriate, probation o?cers is a recent development that may have better results. Many drinkers ?nd the voluntary organisation Alcoholics Anonymous (AA) and its related groups for relatives (Al-Anon) and teenagers (Alateen) helpful because total abstinence from alcohol is encouraged by intensive psychological and social support from fellow ex-drinkers.
Useful contacts are: Alcoholics Anonymous; Al-Anon Family Groups UK and Eire (including Alateen); Alcohol Concern; Alcohol Focus Scotland; and Alcohol and Substance Misuse.

Alpha-fetoprotein (AFP) can be measured in the maternal blood from the latter part of the 1st trimester of pregnancy, and its concentration rises between the 15th and 20th weeks.
Raised levels of are associated with fetal neural tube defects, such as spina bifida or anencephaly, and certain kidney abnormalities. High levels of also occur in multiple pregnancies (see pregnancy, multiple) and threatened or actual miscarriage. levels may be unusually low if the fetus has Down’s syndrome. For this reason, measurement of blood is included in blood tests, which are used to screen pregnant women for an increased risk of Down’s syndrome.

About the Nutrients in This Food Asparagus has some dietary fiber, vitamin A, and vitamin C. It is an excel- lent source of the B vitamin folate. A serving of four cooked asparagus spears (½ inch wide at the base) has 1.2 g dietary fiber, 604 IU vitamin A (26 percent of the R DA for a woman, 20 percent of the R DA for a man), 4.5 mg vitamin C (6 percent of the R DA for a woman, 5 percent of the R DA for a man), and 89 mcg folate (22 percent of the R DA).
The Most Nutritious Way to Serve This Food Fresh, boiled and drained. Canned asparagus may have less than half the nutrients found in freshly cooked spears.
Diets That May Restrict or Exclude This Food Low-sodium diet (canned asparagus)
Buying This Food Look for: Bright green stalks. The tips should be purplish and tightly closed; the stalks should be firm. Asparagus is in season from March through August. Avoid: Wilted stalks and asparagus whose buds have opened.
Storing This Food Store fresh asparagus in the refrigerator. To keep it as crisp as possible, wrap it in a damp paper towel and then put the whole package into a plastic bag. Keeping asparagus cool helps it hold onto its vitamins. At 32°F, asparagus will retain all its folic acid for at least two weeks and nearly 80 percent of its vitamin C for up to five days; at room temperature, it would lose up to 75 percent of its folic acid in three days and 50 percent of the vitamin C in 24 hours.
Preparing This Food The white part of the fresh green asparagus stalk is woody and tasteless, so you can bend the stalk and snap it right at the line where the green begins to turn white. If the skin is very thick, peel it, but save the parings for soup stock.
What Happens When You Cook This Food Chlorophyll, the pigment that makes green vegetables green, is sensitive to acids. When you heat asparagus, its chlorophyll will react chemically with acids in the asparagus or in the cooking water to form pheophytin, which is brown. As a result, cooked asparagus is olive-drab. You can prevent this chemical reaction by cooking the asparagus so quickly that there is no time for the chlorophyll to react with acids, or by cooking it in lots of water (which will dilute the acids), or by leaving the lid off the pot so that the volatile acids can float off into the air. Cooking also changes the texture of asparagus: water escapes from its cells and they collapse. Adding salt to the cooking liquid slows the loss of moisture.
How Other Kinds of Processing Affect This Food Canning. The intense heat of can ning makes asparagus soft, robs it of its bright green color, and reduces the vitamin A, B, and C content by at least half. ( White asparagus, which is bleached to remove the green color, contains about 5 percent of the vitamin A in fresh asparagus.) With its liquid, can ned asparagus, green or white, contains about 90 times the sodium in fresh asparagus ( 348 mg in 3.5 oz. can ned against 4 mg in 3.5 oz. fresh boiled asparagus).
Medical Uses and/or Benefits Lower risk of some birth defects. As many as two of every 1,000 babies born in the United States each year may have cleft palate or a neural tube (spinal cord) defect due to their moth- ers’ not having gotten adequate amounts of folate during pregnancy. The R DA for folate is 400 mcg for healthy adult men and women, 600 mcg for pregnant women, and 500 mcg for women who are nursing. Taking folate supplements before becoming pregnant and through the first two months of pregnancy reduces the risk of cleft palate; taking folate through the entire pregnancy reduces the risk of neural tube defects. Lower risk of heart attack. In the spring of 1998, an analysis of data from the records for more than 80,000 women enrolled in the long-running Nurses’ Health Study at Harvard School of Public Health/Brigham and Woman’s Hospital, in Boston, demonstrated that a diet providing more than 400 mcg folate and 3 mg vitamin B6 daily, from either food or supplements, more than twice the current R DA for each, may reduce a woman’s risk of heart attack by almost 50 percent. Although men were not included in the analysis, the results are assumed to apply to them as well. However, data from a meta-analysis published in the Journal of the American Medical Association in December 2006 called this theory into question. Researchers at Tulane Univer- sity examined the results of 12 controlled studies in which 16,958 patients with preexisting cardiovascular disease were given either folic acid supplements or placebos (“look-alike” pills with no folic acid) for at least six months. The scientists, who found no reduction in the risk of further heart disease or overall death rates among those taking folic acid, concluded that further studies will be required to verify whether taking folic acid supplements reduces the risk of cardiovascular disease.
Adverse Effects Associated with This Food Odorous urine. After eating asparagus, we all excrete the sulfur compound methyl mercap- tan, a smelly waste product, in our urine.
Food/Drug Interactions Anticoagulants. Asparagus is high in vitamin K, a vitamin manufactured naturally by bac- teria in our intestines, an adequate supply of which enables blood to clot normally. Eating foods that contain this vitamin may interfere with the effectiveness of anticoagulants such as heparin and warfarin (Coumadin, Dicumarol, Panwarfin) whose job is to thin blood and dissolve clots....

This technique is used when normal methods of attempted CONCEPTION or ARTIFICIAL INSEMINATION with healthy SEMEN have failed. In the UK, assisted-conception procedures are governed by the Human Fertilisation & Embryology Act 1990, which set up the Human Fertilisation & Embryology Authority (HFEA).
Human Fertilisation & Embryology Act 1990 UK legislation was prompted by the report on in vitro fertilisation produced by a government-appointed committee chaired by Baroness Warnock. This followed the birth, in 1978, of the ?rst ‘test-tube’ baby.
This Act allows regulation monitoring of all treatment centres to ensure that they carry out treatment and research responsibly. It covers any fertilisation that uses donated eggs or sperm (called gametes) – for example, donor insemination or embryos (see EMBRYO) grown outside the human body (known as licensed treatment). The Act also covers research on human embryos with especial emphasis on foolproof labelling and immaculate data collection.
Human Fertilisation & EmbryologyAuthority (HFEA) Set up by the UK government following the Warnock report, the Authority’s 221 members inspect and license centres carrying out fertilisation treatments using donated eggs and sperm. It publishes a code of practice advising centres on how to conduct their activities and maintains a register of information on donors, patients and all treatments. It also reviews routinely progress and research in fertility treatment and the attempted development of human CLONING. Cloning to produce viable embryos (reproductive cloning) is forbidden, but limited licensing of the technique is allowed in specialist centres to enable them to produce cells for medical treatment (therapeutic cloning).
In vitro fertilisation (IVF) In this technique, the female partner receives drugs to enhance OVULATION. Just before the eggs are released from the ovary (see OVARIES), several ripe eggs are collected under ULTRASOUND guidance or through a LAPAROSCOPE. The eggs are incubated with the prepared sperm. About 40 hours later, once the eggs are fertilised, two eggs (three in special circumstances) are transferred into the mother’s UTERUS via the cervix (neck of the womb). Pregnancy should then proceed normally. About one in ?ve IVF pregnancies results in the birth of a child. The success rate is lower in women over 40.
Indications In women with severely damaged FALLOPIAN TUBES, IVF o?ers the only chance of pregnancy. The method is also used in couples with unexplained infertility or with male-factor infertility (where sperms are abnormal or their count low). Women who have had an early or surgically induced MENOPAUSE can become pregnant using donor eggs. A quarter of these pregnancies are multiple – that is, produce twins or more. Twins and triplets are more likely to be premature. The main danger of ovarian stimulation for IVF is hyperstimulation which can cause ovarian cysts. (See OVARIES, DISEASES OF.)... Medical Dictionary

About the Nutrients in This Food The avocado is an unusual fruit because about 16 percent of its total weight is fat, primarily monounsaturated fatty acids. Like many other fruits, avo- cados are high in fiber (the Florida avocado is very high in fiber), a good source of the B vitamin folate, vitamin C, and potassium. The edible part of half of one average size avocado (100 g/3.5 ounces) provides 6.7 g dietary fiber, 15 g fat (2.1 g saturated fat, 9.7 g monoun- saturated fat, 1.8 g polyunsaturated fat), 81 mcg folate (20 percent of the R DA), 20 mg vitamin C (26 percent of the R DA for a woman, 22 percent for a man), and 485 mg potassium (the equivalent of one eight-ounce cup of fresh orange juice). The edible part of one-half a Florida avocado (a.k.a. alligator pear) has eight grams dietary fiber, 13.5 g fat (2.65 g saturated fat), 81 mcg folate (41 percent of the R DA for a man, 45 percent of the R DA for a woman), 12 mg vitamin C (20 percent of the R DA), and 741 mg potassium, 50 percent more than one cup fresh orange juice.
Diets That May Exclude or Restrict This Food Controlled-potassium diet Low-fat diet
Buying This Food Look for: Fruit that feels heavy for its size. The avocados most commonly sold in the U.S. are the Hass—a purple-black bumpy fruit that accounts for 85 percent of the avocados shipped from California—and the smooth-skinned Florida avocado (“alligator pear”). The oval, midwinter Bacon; the pear-shaped, late-fall Fuerte; the Gwen, a slightly larger Hass; Pinkerton, pear-shaped with a smaller seed; the round summer Reed; and the yellow-green, pear-shaped Zutano. Avoid: Avocados with soft dark spots on the skin that indicate damage underneath.
Storing This Food Store hard, unripened avocados in a warm place; a bowl on top of the refrigerator will do. Avocados are shipped before they ripen, when the flesh is hard enough to resist bruising in transit, but they ripen off the tree and will soften nicely at home. Store soft, ripe avocados in the refrigerator to slow the natural enzyme action that turns their flesh brown as they mature even when the fruit has not been cut.
Preparing This Food When you peel or slice an avocado, you tear its cell walls, releasing polyphenoloxidase, an enzyme that converts phenols in the avocado to brownish compounds that darken the avocado’s naturally pale green flesh. You can slow this reaction (but not stop it completely) by brushing the exposed surface of the avocado with an acid (lemon juice or vinegar). To store a cut avocado, brush it with lemon juice or vinegar, wrap it tightly in plastic, and keep it in the refrigerator—where it will eventually turn brown. Or you can store the avocado as guacamole; mixing it with lemon juice, tomatoes, onions, and mayonnaise (all of which are acidic) is an efficient way to protect the color of the fruit.
Medical Uses and/or Benefits Lower risk of some birth defects. As many as two of every 1,000 babies born in the United States each year may have cleft palate or a neural tube (spinal cord) defect due to their moth- ers’ not having gotten adequate amounts of folate during pregnancy. The current R DA for folate is 180 mcg for a healthy woman and 200 mcg for a healthy man, but the FDA now recommends 400 mcg for a woman who is or may become pregnant. Taking folate supple- ments before becoming pregnant and through the first two months of pregnancy reduces the risk of cleft palate; taking folate through the entire pregnancy reduces the risk of neural tube defects. Lower risk of heart attack. In the spring of 1998, an analysis of data from the records for more than 80,000 women enrolled in the long-running Nurses’ Health Study at Harvard School of Public Health/Brigham and Woman’s Hospital, in Boston, demonstrated that a diet providing more than 400 mcg folate and 3 mg vitamin B6 daily, from either food or supplements, more than twice the current R DA for each, may reduce a woman’s risk of heart attack by almost 50 percent. Although men were not included in the analysis, the results are assumed to apply to them as well. However, data from a meta-analysis published in the Journal of the American Medical Association in December 2006 called this theory into question. Researchers at Tulane Univer- sity examined the results of 12 controlled studies in which 16,958 patients with preexisting cardiovascular disease were given either folic acid supplements or placebos (“look-alike” pills with no folic acid) for at least six months. The scientists, who found no reduction in the risk of further heart disease or overall death rates among those taking folic acid, concluded that further studies will be required to ascertain whether taking folic acid supplements reduces the risk of cardiovascular disease. Lower levels of cholesterol. Avocados are rich in oleic acid, a monounsaturated fat believed to reduce cholesterol levels. Potassium benefits. Because potassium is excreted in urine, potassium-rich foods are often recommended for people taking diuretics. In addition, a diet rich in potassium (from food) is associated with a lower risk of stroke. A 1998 Harvard School of Public Health analysis of data from the long-running Health Professionals Study shows 38 percent fewer strokes among men who ate nine servings of high potassium foods a day vs. those who ate less than four servings. Among men with high blood pressure, taking a daily 1,000 mg potas- sium supplement—about the amount of potassium in one avocado—reduced the incidence of stroke by 60 percent.
Adverse Effects Associated with This Food Latex-fruit syndrome. Latex is a milky fluid obtained from the rubber tree and used to make medical and surgical products such as condoms and protective latex gloves, as well as rubber bands, balloons, and toys; elastic used in clothing; pacifiers and baby-bottle nipples; chewing gum; and various adhesives. Some of the proteins in latex are allergenic, known to cause reactions ranging from mild to potentially life-threatening. Some of the pro- teins found naturally in latex also occur naturally in foods from plants such as avocados, bananas, chestnuts, kiwi fruit, tomatoes, and food and diet sodas sweetened with aspar- tame. Persons sensitive to these foods are likely to be sensitive to latex as well. NOT E : The National Institute of Health Sciences, in Japan, also lists the following foods as suspect: A lmonds, apples, apricots, bamboo shoots, bell peppers, buckwheat, cantaloupe, carrots, celer y, cherries, chestnuts, coconut, figs, grapefruit, lettuce, loquat, mangoes, mushrooms, mustard, nectarines, oranges, passion fruit, papaya, peaches, peanuts, peppermint, pine- apples, potatoes, soybeans, strawberries, walnuts, and watermelon.
Food/Drug Interactions MAO inhibitors. Monoamine oxidase (M AO) inhibitors are drugs used as antidepressants or antihypertensives. They inhibit the action of enzymes that break down the amino acid tyramine so it can be eliminated from the body. Tyramine is a pressor amine, a chemical that constricts blood vessels and raises blood pressure. If you eat a food such as avocado that contains tyramine while you are taking an M AO inhibitor you cannot eliminate the pressor amine, and the result may be abnormally high blood pressure or a hypertensive crisis (sus- tained elevated blood pressure). False-positive test for tumors. Carcinoid tumors (which may arise from tissues in the endo- crine system, the intestines, or the lungs) secrete serotonin, a natural chemical that makes blood vessels expand or contract. Because serotonin is excreted in urine, these tumors are diagnosed by measuring the levels of serotonin by-products in the urine. Avocados contain large amounts of serotonin; eating them in the three days before a test for an endocrine tumor might produce a false-positive result, suggesting that you have the tumor when in fact you don’t. (Other foods high in serotonin are bananas, eggplant, pineapples, plums, tomatoes, and walnuts.)... A Nutritional, Medical and Culinary Guide

About the Nutrients in This Food Because beans use stored starches and sugars to produce green shoots called sprouts, sprouted beans have less carbohydrate than the beans from which they grow. But bean sprouts are a good source of dietary fiber, including insoluble cellulose and lignin in leaf parts and soluble pectins and gums in the bean. The sprouts are also high in the B vitamin folate and vitamin C. One-half cup raw mung bean sprouts has 1.2 mg dietary fiber, 31.5 mcg folate (8 percent of the R DA), and 7 mg vitamin C (9 percent of the R DA for a woman, 7 percent of the R DA for a man). Raw beans contain anti-nutrient chemicals that inhibit the enzymes we use to digest proteins and starches; hemagglutinins (substances that make red blood cells clump together); and “factors” that may inactivate vita- min A. These chemicals are usually destroyed when the beans are heated. with the bean must be cooked before serving. Sprouted beans served

Buying This Food Look for: Fresh, crisp sprouts. The tips should be moist and tender. (The shorter the sprout, the more tender it will be.) It is sometimes difficult to judge bean sprouts packed in plastic bags, but you can see through to tell if the tip of the sprout looks fresh. Sprouts sold from water-filled bowls should be refrigerated, protected from dirt and debris, and served with a spoon or tongs, not scooped up by hands. Avoid: Mushy sprouts (they may be decayed) and soft ones (they have lost moisture and vitamin C).
Storing This Food Refrigerate sprouts in a plastic bag to keep them moist and crisp. If you bought them in a plastic bag, take them out and repack them in bags large enough that they do not crush each other. To get the most vitamin C, use the sprouts within a few days.
Preparing This Food R inse the sprouts thoroughly under cold running water to get rid of dirt and sand. Discard any soft or browned sprouts, then cut off the roots and cook the sprouts. Do not tear or cut the sprouts until you are ready to use them. When you slice into the sprouts, you tear cells, releasing enzymes that begin to destroy vitamin C.
What Happens When You Cook This Food Cooking destroys some of the heat-sensitive vitamin C in sprouts. To save it, steam the sprouts quickly, stir-fry them, or add them uncooked just before you serve the dish.
How Other Kinds of Processing Affect This Food Canning. Vitamin C is heat-sensitive, and heating the sprouts during the canning process reduces their vitamin C content.
Medical Uses and/or Benefits Lower risk of some birth defects. As many as t wo of ever y 1,000 babies born in the United States each year may have cleft palate or a neural tube (spinal cord) defect due to their mothers’ not having gotten adequate amounts of folate during pregnancy. The R DA for folate is 400 mcg for healthy adult men and women, 600 mcg for pregnant women, and 500 mcg for women who are nursing. Taking folate supplements before becoming pregnant and continuing through the first t wo months of pregnancy reduces the risk of cleft palate; taking folate through the entire pregnancy reduces the risk of neural tube defects.

Adverse Effects Associated with This Food Food poisoning: Reacting to an outbreak of Salmonella and E. coli O157:H7 food poisoning associated with eating raw alfalfa sprouts, the Food and Drug Administration issued a warn- ing in 1998 and again in summer 1999, cautioning those at high risk of food-borne illness not to eat any raw sprouts. The high-risk group includes children, older adults, and people with a weakened immune system (for example, those who are HIV-positive or undergoing cancer chemotherapy). Tests conducted by the U.S. Department of Agriculture in 1999 sug- gest that irradiating raw sprouts and bathing them in an antiseptic solution at the processing plant may eliminate disease organisms and prolong the vegetable’s shelf life; this remains to be proven....

About the Nutrients in This Food Beans are seeds, high in complex carbohydrates including starch and dietary fiber. They have indigestible sugars (stachyose and raffinose), plus insoluble cellulose and lignin in the seed covering and soluble gums and pectins in the bean. The proteins in beans are limited in the essential amino acids methionine and cystine.* All beans are a good source of the B vitamin folate, and iron. One-half cup canned kidney beans has 7.5 g dietary fiber, 65 mcg folate (15 percent of the R DA), and 1.6 mg iron (11 percent of the R DA for a woman, 20 percent of the R DA for a man). Raw beans contain antinutrient chemicals that inactivate enzymes required to digest proteins and carbohydrates. They also contain factors that inactivate vitamin A and also hemagglutinins, substances that make red blood cells clump together. Cooking beans disarms the enzyme inhibi- tors and the anti-vitamin A factors, but not the hemagglutinins. However, the amount of hemagglutinins in the beans is so small that it has no mea- surable effect in your body. * Soybeans are t he only beans t hat contain proteins considered “complete” because t hey contain sufficient amounts of all t he essent ial amino acids.

The Most Nutritious Way to Serve This Food Cooked, to destroy antinutrients. With grains. The proteins in grains are deficient in the essential amino acids lysine and isoleucine but contain sufficient tryptophan, methionine, and cystine; the proteins in beans are exactly the opposite. Together, these foods provide “complete” proteins. With an iron-rich food (meat) or with a vitamin C-rich food (tomatoes). Both enhance your body’s ability to use the iron in the beans. The meat makes your stomach more acid (acid favors iron absorption); the vitamin C may convert the ferric iron in beans into ferrous iron, which is more easily absorbed by the body.

Buying This Food Look for: Smooth-skinned, uniformly sized, evenly colored beans that are free of stones and debris. The good news about beans sold in plastic bags is that the transparent material gives you a chance to see the beans inside; the bad news is that pyridoxine and pyridoxal, the natural forms of vitamin B6, are very sensitive to light. Avoid: Beans sold in bulk. Some B vitamins, such as vitamin B6 (pyridoxine and pyridoxal), are very sensitive to light. In addition, open bins allow insects into the beans, indicated by tiny holes showing where the bug has burrowed into or through the bean. If you choose to buy in bulk, be sure to check for smooth skinned, uniformly sized, evenly colored beans free of holes, stones, and other debris.
Storing This Food Store beans in air- and moistureproof containers in a cool, dark cabinet where they are pro- tected from heat, light, and insects.
Preparing This Food Wash dried beans and pick them over carefully, discarding damaged or withered beans and any that float. (Only withered beans are light enough to float in water.) Cover the beans with water, bring them to a boil, and then set them aside to soak. When you are ready to use the beans, discard the water in which beans have been soaked. Some of the indigestible sugars in the beans that cause intestinal gas when you eat the beans will leach out into the water, making the beans less “gassy.”
What Happens When You Cook This Food When beans are cooked in liquid, their cells absorb water, swell, and eventually rupture, releasing the pectins and gums and nutrients inside. In addition, cooking destroys antinutri- ents in beans, making them more nutritious and safe to eat.
How Other Kinds of Processing Affect This Food Canning. The heat of canning destroys some of the B vitamins in the beans. Vitamin B is water-soluble. You can recover all the lost B vitamins simply by using the liquid in the can, but the liquid also contains the indigestible sugars that cause intestinal gas when you eat beans. Preprocessing. Preprocessed dried beans have already been soaked. They take less time to cook but are lower in B vitamins.
Medical Uses and/or Benefits Lower risk of some birth defects. As many as two of every 1,000 babies born in the United States each year may have cleft palate or a neural tube (spinal cord) defect due to their moth- ers’ not having gotten adequate amounts of folate during pregnancy. The current R DA for folate is 180 mcg for a woman and 200 mcg for a man, but the FDA now recommends 400 mcg for a woman who is or may become pregnant. Taking a folate supplement before becoming pregnant and continuing through the first two months of pregnancy reduces the risk of cleft palate; taking folate through the entire pregnancy reduces the risk of neural tube defects. Lower risk of heart attack. In the spring of 1998, an analysis of data from the records for more than 80,000 women enrolled in the long-run ning Nurses Health Study at Har vard School of Public Health/ Brigham and Woman’s Hospital in Boston demonstrated that a diet providing more than 400 mcg folate and 3 mg vitamin B6 a day from either food or supple- ments, more than t wice the current R DA for each, may reduce a woman’s risk of heart attack by almost 50 percent. A lthough men were not included in the analysis, the results are assumed to apply to them as well. NOT E : Beans are high in B6 as well as folate. Fruit, green leaf y vegetables, whole grains, meat, fish, poultr y, and shellfish are good sources of vitamin B6. To reduce the levels of serum cholesterol. The gums and pectins in dried beans and peas appear to lower blood levels of cholesterol. Currently there are two theories to explain how this may happen. The first theory is that the pectins in the beans form a gel in your stomach that sops up fats and keeps them from being absorbed by your body. The second is that bacteria in the gut feed on the bean fiber, producing short-chain fatty acids that inhibit the production of cholesterol in your liver. As a source of carbohydrates for people with diabetes. Beans are digested very slowly, produc- ing only a gradual rise in blood-sugar levels. As a result, the body needs less insulin to control blood sugar after eating beans than after eating some other high-carbohydrate foods (such as bread or potato). In studies at the University of Kentucky, a bean, whole-grain, vegetable, and fruit-rich diet developed at the University of Toronto enabled patients with type 1 dia- betes (who do not produce any insulin themselves) to cut their daily insulin intake by 38 percent. Patients with type 2 diabetes (who can produce some insulin) were able to reduce their insulin injections by 98 percent. This diet is in line with the nutritional guidelines of the American Diabetes Association, but people with diabetes should always consult with their doctors and/or dietitians before altering their diet. As a diet aid. Although beans are high in calories, they are also high in bulk (fiber); even a small serving can make you feel full. And, because they are insulin-sparing, they delay the rise in insulin levels that makes us feel hungry again soon after eating. Research at the University of Toronto suggests the insulin-sparing effect may last for several hours after you eat the beans, perhaps until after the next meal.
Adverse Effects Associated with This Food Intestinal gas. All legumes (beans and peas) contain raffinose and stachyose, complex sug- ars that human beings cannot digest. The sugars sit in the gut and are fermented by intestinal bacteria which then produce gas that distends the intestines and makes us uncomfortable. You can lessen this effect by covering the beans with water, bringing them to a boil for three to five minutes, and then setting them aside to soak for four to six hours so that the indigestible sugars leach out in the soaking water, which can be discarded. Alternatively, you may soak the beans for four hours in nine cups of water for every cup of beans, discard the soaking water, and add new water as your recipe directs. Then cook the beans; drain them before serving. Production of uric acid. Purines are the natural metabolic by-products of protein metabo- lism in the body. They eventually break down into uric acid, sharp cr ystals that may concentrate in joints, a condition known as gout. If uric acid cr ystals collect in the urine, the result may be kidney stones. Eating dried beans, which are rich in proteins, may raise the concentration of purines in your body. Although controlling the amount of purines in the diet does not significantly affect the course of gout (which is treated with allopurinol, a drug that prevents the formation of uric acid cr ystals), limiting these foods is still part of many gout regimens.
Food/Drug Interactions Monoamine oxidase (MAO) inhibitors. Monoamine oxidase inhibitors are drugs used to treat depression. They inactivate naturally occurring enzymes in your body that metabolize tyramine, a substance found in many fermented or aged foods. Tyramine constricts blood vessels and increases blood pressure. If you eat a food containing tyramine while you are taking an M AO inhibitor, you cannot effectively eliminate the tyramine from your body. The result may be a hypertensive crisis. Some nutrition guides list dried beans as a food to avoid while using M AO inhibitors.... A Nutritional, Medical and Culinary Guide

About the Nutrients in This Food Like fish, pork, poultry, milk, and eggs, beef has high-quality proteins, with sufficient amounts of all the essential amino acids. Beef fat is slightly more highly saturated than pork fat, but less saturated than lamb fat. All have about the same amount of cholesterol per serving. Beef is an excellent source of B vitamins, including niacin, vitamin B6, and vitamin B12, which is found only in animal foods. Lean beef pro- vides heme iron, the organic iron that is about five times more useful to the body than nonheme iron, the inorganic form of iron found in plant foods. Beef is also an excellent source of zinc. One four-ounce serving of lean broiled sirloin steak has nine grams fat (3.5 g saturated fat), 101 mg cholesterol, 34 g protein, and 3.81 mg iron (21 percent of the R DA for a woman, 46 percent of the R DA for a man). One four-ounce serving of lean roast beef has 16 g fat (6.6 g saturated fat), 92 mg cholesterol, and 2.96 mg iron (16 percent of the R DA for a woman, 37 percent of the R DA for a man).

Buying This Food Look for: Fresh, red beef. The fat should be white, not yellow. Choose lean cuts of beef with as little internal marbling (streaks of fat) as possible. The leanest cuts are flank steak and round steak; rib steaks, brisket, and chuck have the most fat. USDA grading, which is determined by the maturity of the animal and marbling in meat, is also a guide to fat content. U.S. prime has more marbling than U.S. choice, which has more marbling than U.S. good. All are equally nutritious; the difference is how tender they are, which depends on how much fat is present. Choose the cut of meat that is right for your recipe. Generally, the cuts from the cen- ter of the animal’s back—the rib, the T-Bone, the porterhouse steaks—are the most tender. They can be cooked by dry heat—broiling, roasting, pan-frying. Cuts from around the legs, the underbelly, and the neck—the shank, the brisket, the round—contain muscles used for movement. They must be tenderized by stewing or boiling, the long, moist cooking methods that break down the connective tissue that makes meat tough.
Storing This Food Refrigerate raw beef immediately, carefully wrapped to prevent its drippings from contami- nating other foods. Refrigeration prolongs the freshness of beef by slowing the natural multi- plication of bacteria on the meat surface. Unchecked, these bacteria will convert proteins and other substances on the surface of the meat to a slimy film and change meat’s sulfur-contain- ing amino acids methionine and cystine into smelly chemicals called mercaptans. When the mercaptans combine with myoglobin, they produce the greenish pigment that gives spoiled meat its characteristic unpleasant appearance. Fresh ground beef, with many surfaces where bacteria can live, should be used within 24 to 48 hours. Other cuts of beef may stay fresh in the refrigerator for three to five days.
Preparing This Food Trim the beef carefully. By judiciously cutting away all visible fat you can significantly reduce the amount of fat and cholesterol in each serving. When you are done, clean all utensils thoroughly with soap and hot water. Wash your cutting board, wood or plastic, with hot water, soap, and a bleach-and-water solution. For ultimate safety in preventing the transfer of microorganisms from the raw meat to other foods, keep one cutting board exclusively for raw meats, fish, and poultry, and a second one for everything else. Finally, don’t forget to wash your hands.
What Happens When You Cook This Food Cooking changes the appearance and flavor of beef, alters nutritional value, makes it safer, and extends its shelf life. Browning meat after you cook it does not “seal in the juices,” but it does change the fla- vor by caramelizing sugars on the surface. Because beef’s only sugars are the small amounts of glycogen in the muscles, we add sugars in marinades or basting liquids that may also con- tain acids (vinegar, lemon juice, wine) to break down muscle fibers and tenderize the meat. (Browning has one minor nutritional drawback. It breaks amino acids on the surface of the meat into smaller compounds that are no longer useful proteins.) When beef is cooked, it loses water and shrinks. Its pigments, which combine with oxygen, are denatured (broken into fragments) by the heat and turn brown, the natural color of well-done meat. At the same time, the fats in the beef are oxidized. Oxidized fats, whether formed in cooking or when the cooked meat is stored in the refrigerator, give cooked meat a character- istic warmed-over flavor. Cooking and storing meat under a blanket of antioxidants—catsup or a gravy made of tomatoes, peppers, and other vitamin C-rich vegetables—reduces the oxidation of fats and the intensity of warmed-over flavor. Meat reheated in a microwave oven also has less warmed-over flavor. An obvious nutritional benefit of cooking is the fact that heat lowers the fat content of beef by liquif ying the fat so it can run off the meat. One concrete example of how well this works comes from a comparison of the fat content in regular and extra-lean ground beef. According to research at the University of Missouri in 1985, both kinds of beef lose mass when cooked, but the lean beef loses water and the regular beef loses fat and cholesterol. Thus, while regular raw ground beef has about three times as much fat (by weight) as raw ground extra-lean beef, their fat varies by only 5 percent after broiling. To reduce the amount of fat in ground beef, heat the beef in a pan until it browns. Then put the beef in a colander, and pour one cup of warm water over the beef. Repeat with a second cup of warm water to rinse away fat melted by heating the beef. Use the ground beef in sauce and other dishes that do not require it to hold together. Finally, cooking makes beef safer by killing Salmonella and other organisms in the meat. As a result, cooking also serves as a natural preservative. According to the USDA, large pieces of fresh beef can be refrigerated for two or three days, then cooked and held safely for another day or two because the heat of cooking has reduced the number of bacteria on the surface of the meat and temporarily interrupted the natural cycle of deterioration.
How Other Kinds of Processing Affect This Food Aging. Hanging fresh meat exposed to the air, in a refrigerated room, reduces the moisture content and shrinks the meat slightly. As the meat ages enzymes break down muscle pro- teins, “tenderizing” the beef. Canning. Canned beef does not develop a warmed-over flavor because the high tempera- tures in canning food and the long cooking process alter proteins in the meat so that they act as antioxidants. Once the can is open, however, the meat should be protected from oxygen that will change the flavor of the beef. Curing. Salt-curing preserves meat through osmosis, the physical reaction in which liquids flow across a membrane, such as the wall of a cell, from a less dense to a more dense solution. The salt or sugar used in curing dissolves in the liquid on the surface of the meat to make a solution that is more dense than the liquid inside the cells of the meat. Water flows out of the meat and out of the cells of any microorganisms living on the meat, killing the microor- ganisms and protecting the meat from bacterial damage. Salt-cured meat is much higher in sodium than fresh meat. Freezing. When you freeze beef, the water inside its cells freezes into sharp ice crystals that can puncture cell membranes. When the beef thaws, moisture (and some of the B vitamins) will leak out through these torn cell walls. The loss of moisture is irreversible, but some of the vitamins can be saved by using the drippings when the meat is cooked. Freezing may also cause freezer burn—dry spots left when moisture evaporates from the surface of the meat. Waxed freezer paper is designed specifically to hold the moisture in meat; plastic wrap and aluminum foil are less effective. NOTE : Commercially prepared beef, which is frozen very quickly at very low temperatures, is less likely to show changes in texture. Irradiation. Irradiation makes meat safer by exposing it to gamma rays, the kind of high- energy ionizing radiation that kills living cells, including bacteria. Irradiation does not change the way meat looks, feels or tastes, or make the food radioactive, but it does alter the structure of some naturally occurring chemicals in beef, breaking molecules apart to form new com- pounds called radiolytic products (R P). About 90 percent of R Ps are also found in nonirradiated foods. The rest, called unique radiolytic products (UR P), are found only in irradiated foods. There is currently no evidence to suggest that UR Ps are harmful; irradiation is an approved technique in more than 37 countries around the world, including the United States. Smoking. Hanging cured or salted meat over an open fire slowly dries the meat, kills micro- organisms on its surface, and gives the meat a rich, “smoky” flavor that varies with the wood used in the fire. Meats smoked over an open fire are exposed to carcinogenic chemicals in the smoke, including a-benzopyrene. Meats treated with “artificial smoke flavoring” are not, since the flavoring is commercially treated to remove tar and a-benzopyrene.
Medical Uses and/or Benefits Treating and/or preventing iron deficiency. Without meat in the diet, it is virtually impossible for an adult woman to meet her iron requirement without supplements. One cooked 3.5- ounce hamburger provides about 2.9 mg iron, 16 percent of the R DA for an adult woman of childbearing age. Possible anti-diabetes activity. CLA may also prevent type 2 diabetes, also called adult-onset diabetes, a non-insulin-dependent form of the disease. At Purdue University, rats bred to develop diabetes spontaneously between eight and 10 weeks of age stayed healthy when given CLA supplements.
Adverse Effects Associated with This Food Increased risk of heart disease. Like other foods from animals, beef contains cholesterol and saturated fats that increase the amount of cholesterol circulating in your blood, raising your risk of heart disease. To reduce the risk of heart disease, the National Cholesterol Education Project recommends following the Step I and Step II diets. 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) Increased risk of some cancers. According the American Institute for Cancer Research, a diet high in red meat (beef, lamb, pork) increases the risk of developing colorectal cancer by 15 percent for every 1.5 ounces over 18 ounces consumed per week. In 2007, the National Can- cer Institute released data from a survey of 500,000 people, ages 50 to 71, who participated in an eight-year A AR P diet and health study identif ying a higher risk of developing cancer of the esophagus, liver, lung, and pancreas among people eating large amounts of red meats and processed meats. Food-borne illness. Improperly cooked meat contaminated with E. coli O157:H7 has been linked to a number of fatalities in several parts of the United States. In addition, meats con- taminated with other bacteria, viruses, or parasites pose special problems for people with a weakened immune system: the very young, the very old, cancer chemotherapy patients, and people with HIV. Cooking meat to an internal temperature of 140°F should destroy Salmo- nella and Campylobacter jejuni; 165°F, the E. coli organism; and 212°F, Listeria monocytogenes. Antibiotic sensitivity. Cattle in the United States are routinely given antibiotics to protect them from infection. By law, the antibiotic treatment must stop three days to several weeks before the animal is slaughtered. Theoretically, the beef should then be free of antibiotic residues, but some people who are sensitive to penicillin or tetracycline may have an allergic reaction to the meat, although this is rare. Antibiotic-resistant Salmonella and toxoplasmosis. Cattle treated with antibiotics may pro- duce meat contaminated with antibiotic-resistant strains of Salmonella, and all raw beef may harbor ordinary Salmonella as well as T. gondii, the parasite that causes toxoplasmosis. Toxoplasmosis is particularly hazardous for pregnant women. It can be passed on to the fetus and may trigger a series of birth defects including blindness and mental retardation. Both Salmonella and the T. gondii can be eliminated by cooking meat thoroughly and washing all utensils, cutting boards, and counters as well as your hands with hot soapy water before touching any other food. Decline in kidney function. Proteins are nitrogen compounds. When metabolized, they yield ammonia, which is excreted through the kidneys. In laborator y animals, a sustained high-protein diet increases the flow of blood through the kidneys, accelerating the natural age-related decline in kidney function. Some experts suggest that this may also occur in human beings.
Food/Drug Interactions Tetracycline antibiotics (demeclocycline [Declomycin], doxycycline [ Vibtamycin], methacycline [Rondomycin], minocycline [Minocin], oxytetracycline [Terramycin], tetracycline [Achromycin V, Panmycin, Sumycin]). Because meat contains iron, which binds tetracyclines into com- pounds the body cannot absorb, it is best to avoid meat for two hours before and after taking one of these antibiotics. Monoamine oxidase (MAO) inhibitors. Meat “tenderized” with papaya or a papain powder can interact with the class of antidepressant drugs known as monoamine oxidase inhibi- tors. Papain meat tenderizers work by breaking up the long chains of protein molecules. One by-product of this process is tyramine, a substance that constructs blood vessels and raises blood pressure. M AO inhibitors inactivate naturally occurring enzymes in your body that metabolize tyramine. If you eat a food such as papain-tenderized meat, which is high in tyramine, while you are taking a M AO inhibitor, you cannot effectively eliminate the tyramine from your body. The result may be a hypertensive crisis. Theophylline. Charcoal-broiled beef appears to reduce the effectiveness of theophylline because the aromatic chemicals produced by burning fat speed up the metabolism of the- ophylline in the liver....

About the Nutrients in This Food Beer and ale are fermented beverages created by yeasts that convert the sugars in malted barley and grain to ethyl alcohol (a.k.a. “alcohol,” “drink- ing alcohol”).* The USDA /Health and Human Services Dietary Guidelines for Americans defines one drink as 12 ounces of beer, five ounces of wine, or 1.25 ounces of distilled spirits. One 12-ounce glass of beer has 140 calo- ries, 86 of them (61 percent) from alcohol. But the beverage—sometimes nicknamed “liquid bread”—is more than empty calories. Like wine, beer retains small amounts of some nutrients present in the food from which it was made. * Because yeasts cannot digest t he starches in grains, t he grains to be used in mak ing beer and ale are allowed to germinate ( “malt” ). When it is t ime to make t he beer or ale, t he malted grain is soaked in water, forming a mash in which t he starches are split into simple sugars t hat can be digested (fermented) by t he yeasts. If undisturbed, t he fermentat ion will cont inue unt il all t he sugars have been digested, but it can be halted at any t ime simply by raising or lowering t he temperature of t he liquid. Beer sold in bott les or cans is pasteurized to k ill t he yeasts and stop t he fermentat ion. Draft beer is not pasteurized and must be refrigerated unt il tapped so t hat it will not cont inue to ferment in t he container. The longer t he shipping t ime, t he more likely it is t hat draft beer will be exposed to temperature variat ions t hat may affect its qualit y—which is why draft beer almost always tastes best when consumed near t he place where it was brewed.

Buying This Food Look for: A popular brand that sells steadily and will be fresh when you buy it. Avoid: Dusty or warm bottles and cans.
Storing This Food Store beer in a cool place. Beer tastes best when consumed within two months of the day it is made. Since you cannot be certain how long it took to ship the beer to the store or how long it has been sitting on the grocery shelves, buy only as much beer as you plan to use within a week or two. Protect bottled beer and open bottles or cans of beer from direct sunlight, which can change sulfur compounds in beer into isopentyl mercaptan, the smelly chemical that gives stale beer its characteristic unpleasant odor.
When You Are Ready to Serve This Food Serve beer only in absolutely clean glasses or mugs. Even the slightest bit of grease on the side of the glass will kill the foam immediately. Wash beer glasses with detergent, not soap, and let them drain dry rather than drying them with a towel that might carry grease from your hands to the glass. If you like a long-lasting head on your beer, serve the brew in tall, tapering glasses to let the foam spread out and stabilize. For full flavor, serve beer and ales cool but not ice-cold. Very low temperatures immo- bilize the molecules that give beer and ale their flavor and aroma.
What Happens When You Cook This Food When beer is heated (in a stew or as a basting liquid), the alcohol evaporates but the flavor- ing agents remain intact. Alcohol, an acid, reacts with metal ions from an aluminum or iron pot to form dark compounds that discolor the pot or the dish you are cooking in. To prevent this, prepare dishes made with beer in glass or enameled pots.
Medical Uses and/or Benefits Reduced risk of heart attack. Data from the American Cancer Society’s Cancer Prevention Study 1, a 12-year survey of more than 1 million Americans in 25 states, shows that men who take one drink a day have a 21 percent lower risk of heart attack and a 22 percent lower risk of stroke than men who do not drink at all. Women who have up to one drink a day also reduce their risk of heart attack. Numerous later studies have confirmed these findings. Lower risk of stroke. In January 1999, the results of a 677-person study published by researchers at New York Presbyterian Hospital-Columbia University showed that moder- ate alcohol consumption reduces the risk of stroke due to a blood clot in the brain among older people (average age: 70). How the alcohol prevents stroke is still unknown, but it is clear that moderate use of alcohol is a key. Heavy drinkers (those who consume more than seven drinks a day) have a higher risk of stroke. People who once drank heavily, but cut their consumption to moderate levels, can also reduce their risk of stroke. Numerous later studies have confirmed these findings. Lower cholesterol levels. Beverage alcohol decreases the body’s production and storage of low-density lipoproteins (LDLs), the protein and fat particles that carr y cholesterol into your arteries. As a result, people who drink moderately tend to have lower cholesterol levels and higher levels of high density lipoproteins (HDLs), the fat and protein particles that carr y cholesterol out of the body. The USDA /Health and Human Services Dietar y Guidelines for Americans defines moderation as two drinks a day for a man, one drink a day for a woman. Stimulating the appetite. Alcoholic beverages stimulate the production of saliva and the gastric acids that cause the stomach contractions we call hunger pangs. Moderate amounts of alcoholic beverages, which may help stimulate appetite, are often prescribed for geriatric patients, convalescents, and people who do not have ulcers or other chronic gastric problems that might be exacerbated by the alcohol. Dilation of blood vessels. Alcohol dilates the capillaries (the tiny blood vessels just under the skin), and moderate amounts of alcoholic beverages produce a pleasant flush that temporar- ily warms the drinker. But drinking is not an effective way to warm up in cold weather since the warm blood that flows up to the capillaries will cool down on the surface of your skin and make you even colder when it circulates back into the center of your body. Then an alco- hol flush will make you perspire, so that you lose more heat. Excessive amounts of beverage alcohol may depress the mechanism that regulates body temperature.
Adverse Effects Associated with This Food Increased risk of breast cancer. In 2008, scientists at the National Cancer Institute released data from a seven-year survey of more than 100,000 postmenopausal women showing that even moderate drinking (one to two drinks a day) may increase by 32 percent a woman’s risk of developing estrogen-receptor positive (ER+) and progesterone-receptor positive (PR+) breast cancer, tumors whose growth is stimulated by hormones. No such link was found between consuming alcohol and the risk of developing ER-/PR- tumors (not fueled by hor- mones). The finding applies to all types of alcohol: beer, wine, and spirits. Increased risk of oral cancer (cancer of the mouth and throat). Numerous studies confirm the American Cancer Society’s warning that men and women who consume more than two drinks a day are at higher risk of oral cancer than are nondrinkers or people who drink less. Note: The Dietary Guidelines for Americans describes one drink as 12 ounces of beer, five ounces of wine, or 1.5 ounces of distilled spirits. Increased risk of cancer of the colon and rectum. In the mid-1990s, studies at the University of Oklahoma suggested that men who drink more than five beers a day are at increased risk of rectal cancer. Later studies suggested that men and women who are heavy beer or spirits drinkers (but not those who are heavy wine drinkers) have a higher risk of colorectal cancers. Further studies are required to confirm these findings. Fetal alcohol syndrome. Fetal alcohol syndrome is a specific pattern of birth defects—low birth weight, heart defects, facial malformations, and mental retardation—first recognized in a study of babies born to alcoholic women who consumed more than six drinks a day while pregnant. Subsequent research has found a consistent pattern of milder defects in babies born to women who consume three to four drinks a day or five drinks on any one occasion while pregnant. To date, there is no evidence of a consistent pattern of birth defects in babies born to women who consume less than one drink a day while pregnant, but two studies at Columbia University have suggested that as few as two drinks a week while preg- nant may raise a woman’s risk of miscarriage. (“One drink” means 12 ounces of beer, five ounces of wine, or 1.25 ounces of distilled spirits.) Alcoholism. Alcoholism is an addiction disease, the inability to control one’s alcohol consumption. It is a potentially life-threatening condition, with a higher risk of death by accident, suicide, malnutrition, or acute alcohol poisoning, a toxic reaction that kills by para- lyzing body organs, including the heart. Malnutrition. While moderate alcohol consumption stimulates appetite, alcohol abuse depresses it. In addition, an alcoholic may drink instead of eating. When an alcoholic does eat, excess alcohol in his/her body prevents absorption of nutrients and reduces the ability to synthesize new tissue. Hangover. Alcohol is absorbed from the stomach and small intestine and carried by the bloodstream to the liver, where it is oxidized to acetaldehyde by alcohol dehydrogenase (ADH), the enzyme our bodies use to metabolize the alcohol we produce when we digest carbohydrates. The acetaldehyde is converted to acetyl coenzyme A and either eliminated from the body or used in the synthesis of cholesterol, fatty acids, and body tissues. Although individuals vary widely in their capacity to metabolize alcohol, on average, normal healthy adults can metabolize the alcohol in one quart of beer in approximately five to six hours. If they drink more than that, they will have more alcohol than the body’s natural supply of ADH can handle. The unmetabolized alcohol will pile up in the bloodstream, interfering with the liver’s metabolic functions. Since alcohol decreases the reabsorption of water from the kidneys and may inhibit the secretion of an antidiuretic hormone, they will begin to urinate copiously, losing magnesium, calcium, and zinc but retaining more irritating uric acid. The level of lactic acid in the body will increase, making them feel tired and out of sorts; their acid-base balance will be out of kilter; the blood vessels in their heads will swell and throb; and their stomachs, with linings irritated by the alcohol, will ache. The ultimate result is a “hangover” whose symptoms will disappear only when enough time has passed to allow their bodies to marshal the ADH needed to metabolize the extra alcohol in their blood. Changes in body temperature. Alcohol dilates capillaries, tiny blood vessels just under the skin, producing a “flush” that temporarily warms the drinker. But drinking is not an effective way to stay warm in cold weather. Warm blood flowing up from the body core to the surface capillaries is quickly chilled, making you even colder when it circulates back into your organs. In addition, an alcohol flush triggers perspiration, further cooling your skin. Finally, very large amounts of alcohol may actually depress the mechanism that regulates body temperature. Impotence. Excessive drinking decreases libido (sexual desire) and interferes with the ability to achieve or sustain an erection. “Beer belly.” Data from a 1995, 12,000 person study at the University of North Carolina in Chapel Hill show that people who consume at least six beers a week have more rounded abdomens than people who do not drink beer. The question left to be answered is which came first: the tummy or the drinking.
Food/Drug Interactions Acetaminophen (Tylenol, etc.). The FDA recommends that people who regularly have three or more drinks a day consult a doctor before using acetaminophen. The alcohol/acetamino- phen combination may cause liver failure. Disulfiram (Antabuse). Taken with alcohol, disulfiram causes flushing, nausea, low blood pressure, faintness, respiratory problems, and confusion. The severity of the reaction gener- ally depends on how much alcohol you drink, how much disulfiram is in your body, and how long ago you took it. Disulfiram is used to help recovering alcoholics avoid alcohol. (If taken with alcohol, metronidazole [Flagyl], procarbazine [Matulane], quinacrine [Atabrine], chlorpropamide (Diabinase), and some species of mushrooms may produce a mild disulfi- ramlike reaction.) Anticoagulants. Alcohol slows the body’s metabolism of anticoagulants (blood thinners) such as warfarin (Coumadin), intensif ying the effect of the drugs and increasing the risk of side effects such as spontaneous nosebleeds. Antidepressants. Alcohol may increase the sedative effects of antidepressants. Drinking alcohol while you are taking a monoamine oxidase (M AO) inhibitor is especially hazard- ous. M AO inhibitors inactivate naturally occurring enzymes in your body that metabolize tyramine, a substance found in many fermented or aged foods. Tyramine constricts blood vessels and increases blood pressure. If you eat a food containing tyramine while you are taking an M AO inhibitor, you cannot effectively eliminate the tyramine from your body. The result may be a hypertensive crisis. Ordinarily, fermentation of beer and ale does not produce tyramine, but some patients have reported tyramine reactions after drinking some imported beers. Beer and ale are usually prohibited to those using M AO inhibitors. Aspirin, ibuprofen, ketoprofen, naproxen, and nonsteroidal anti-inflammatory drugs. Like alcohol, these analgesics irritate the lining of the stomach and may cause gastric bleeding. Combining the two intensifies the effect. Insulin and oral hypoglycemics. Alcohol lowers blood sugar and interferes with the metabo- lism of oral antidiabetics; the combination may cause severe hypoglycemia. Sedatives and other central nervous system depressants (tranquilizers, sleeping pills, antidepres- sants, sinus and cold remedies, analgesics, and medication for motion sickness). Alcohol inten- sifies sedation and, depending on the dose, may cause drowsiness, respiratory depression, coma, or death.... A Nutritional, Medical and Culinary Guide

About the Nutrients in This Food Beets are roots, high-carbohydrate foods that provide sugars, starch, and small amounts of dietary fiber, insoluble cellulose in the skin, and soluble pectins in the flesh. Beets are also a good source of the B vitamin folate. One-half cup cooked fresh beets has one gram of dietar y fiber and 68 mcg folate (17 percent of the R DA).
The Most Nutritious Way to Serve This Food Cooked, to dissolve the stiff cell walls and make the nutrients inside available.
Diets That May Restrict or Exclude This Food Anti-kidney-stone diet Low-sodium diet
Buying This Food Look for: Smooth round globes with fresh, crisp green leaves on top. Avoid: Beets with soft spots or blemishes that suggest decay underneath.
Storing This Food Protect the nutrients in beets by storing the vegetables in a cool place, such as the vegetable crisper in your refrigerator. When stored, the beet root converts its starch into sugars; the longer it is stored, the sweeter it becomes. Remove the green tops from beets before storing and store the beet greens like other leaf y vegetables, in plastic bags in the refrigerator to keep them from drying out and losing vitamins (also see gr eens). Use both beets and beet greens within a week.
Preparing This Food Scrub the globes with a vegetable brush under cold running water. You can cook them whole or slice them. Peel before (or after) cooking.
What Happens When You Cook This Food Betacyamin and betaxanthin, the red betalain pigments in beets, are water-soluble. (That’s why borscht is a scarlet soup.) Betacyanins and betaxanthins turn more intensely red when you add acids; think of scarlet sweet-and-sour beets in lemon juice or vinegar with sugar. They turn slightly blue in a basic (alkaline) solution such as baking soda and water. Like carrots, beets have such stiff cell walls that it is hard for the human digestive tract to extract the nutrients inside. Cooking will not soften the cellulose in the beet’s cell walls, but it will dissolve enough hemicellulose so that digestive juices are able to penetrate. Cook- ing also activates flavor molecules in beets, making them taste better.
How Other Kinds of Processing Affect This Food Canning. Beets lose neither their color nor their texture in canning.
Medical Uses and/or Benefits Lower risk of some birth defects. As many as two of every 1,000 babies born in the United States each year may have cleft palate or a neural tube (spinal cord) defect due to their moth- ers’ not having gotten adequate amounts of folate during pregnancy. The R DA for folate is 400 mcg for healthy adult men and women, 600 mcg for pregnant women, and 500 mcg for women who are nursing. Taking folate supplements before becoming pregnant and continu- ing through the first two months of pregnancy reduces the risk of cleft palate; taking folate through the entire pregnancy reduces the risk of neural tube defects. Possible lower risk of heart attack. In the spring of 1998, an analysis of data from the records of more than 80,000 women enrolled in the long-running Nurses’ Health Study at Harvard School of Public Health/Brigham and Women’s Hospital, in Boston, demonstrated that a diet providing more than 400 mcg folate and 3 mg vitamin B6 daily, either from food or supple- ments, might reduce a woman’s risk of heart attack by almost 50 percent. Although men were not included in the study, the results were assumed to apply to them as well. However, data from a meta-analysis published in the Journal of the American Medical Association in December 2006 called this theory into question. Researchers at Tulane Univer- sity examined the results of 12 controlled studies in which 16,958 patients with preexisting cardiovascular diseases were given either folic acid supplements or placebos (“look-alike” pills with no folic acid) for at least six months. The scientists, who found no reduction in the risk of further heart disease or overall death rates among those taking folic acid, concluded that further studies will be required to verif y whether taking folic acid supplements reduces the risk of cardiovascular disease.
Adverse Effects Associated with This Food Pigmented urine and feces. The ability to metabolize betacyanins and be taxanthins is a genetic trait. People with two recessive genes for this trait cannot break down these red pig- ments, which will be excreted, bright red, in urine. Eating beets can also turn feces red, but it will not cause a false-positive result in a test for occult blood in the stool. Nitrosamine formation. Beets, celery, eggplant, lettuce, radishes, spinach, and collard and turnip greens contain nitrates that convert naturally into nitrites in your stomach—where some of the nitrites combine with amines to form nitrosamines, some of which are known carcinogens. This natural chemical reaction presents no known problems for a healthy adult. However, when these vegetables are cooked and left standing for a while at room tempera- ture, microorganisms that convert nitrates to nitrites begin to multiply, and the amount of nitrites in the food rises. The resulting higher-nitrite foods may be dangerous for infants (see spinach).... A Nutritional, Medical and Culinary Guide

In blood transfusion, the person giving and the person receiving the blood must belong to the same blood group, or a dangerous reaction will take place from the agglutination that occurs when blood of a di?erent group is present. One exception is that group O Rhesus-negative blood can be used in an emergency for anybody.

Rhesus factor In addition to the A and B agglutinogens (or antigens), there is another one known as the Rhesus (or Rh) factor – so named because there is a similar antigen in the red blood corpuscles of the Rhesus monkey. About 84 per cent of the population have this Rh factor in their blood and are therefore known as ‘Rh-positive’. The remaining 16 per cent who do not possess the factor are known as ‘Rh-negative’.
The practical importance of the Rh factor is that, unlike the A and B agglutinogens, there are no naturally occurring Rh antibodies. However, such antibodies may develop in a Rh-negative person if the Rh antigen is introduced into his or her circulation. This can occur (a) if a Rh-negative person is given a transfusion of Rh-positive blood, and (b) if a Rh-negative mother married to a Rh-positive husband becomes pregnant and the fetus is Rh-positive. If the latter happens, the mother develops Rh antibodies which can pass into the fetal circulation, where they react with the baby’s Rh antigen and cause HAEMOLYTIC DISEASE of the fetus and newborn. This means that, untreated, the child may be stillborn or become jaundiced shortly after birth.
As about one in six expectant mothers is Rh-negative, a blood-group examination is now considered an essential part of the antenatal examination of a pregnant woman. All such Rh-negative expectant mothers are now given a ‘Rhesus card’ showing that they belong to the rhesus-negative blood group. This card should always be carried with them. Rh-positive blood should never be transfused to a Rh-negative girl or woman.... Medical Dictionary

About the Nutrients in This Food Broccoli is very high-fiber food, an excellent source of vitamin A, the B vitamin folate, and vitamin C. It also has some vitamin E and vitamin K, the blood-clotting vitamin manufactured primarily by bacteria living in our intestinal tract. One cooked, fresh broccoli spear has five grams of dietary fiber, 2,500 IU vitamin A (108 percent of the R DA for a woman, 85 percent of the R DA for a man), 90 mcg folate (23 percent of the R DA), and 130 mg vitamin C (178 percent of the R DA for a woman, 149 percent of the R DA for a man).
The Most Nutritious Way to Serve This Food Raw. Studies at the USDA Agricultural Research Center in Beltsville, Maryland, show that raw broccoli has up to 40 percent more vitamin C than broccoli that has been cooked or frozen.
Diets That May Restrict or Exclude This Food Antiflatulence diet Low-fiber diet
Buying This Food Look for: Broccoli with tightly closed buds. The stalk, leaves, and florets should be fresh, firm, and brightly colored. Broccoli is usually green; some varieties are tinged with purple. Avoid: Broccoli with woody stalk or florets that are open or turning yellow. When the green chlorophyll pigments fade enough to let the yellow carotenoids underneath show through, the buds are about to bloom and the broccoli is past its prime.
Storing This Food Pack broccoli in a plastic bag and store it in the refrigerator or in the vegetable crisper to protect its vitamin C. At 32°F, fresh broccoli can hold onto its vitamin C for as long as two weeks. Keep broccoli out of the light; like heat, light destroys vitamin C.
Preparing This Food First, rinse the broccoli under cool running water to wash off any dirt and debris clinging to the florets. Then put the broccoli, florets down, into a pan of salt water (1 tsp. salt to 1 qt. water) and soak for 15 to 30 minutes to drive out insects hiding in the florets. Then cut off the leaves and trim away woody section of stalks. For fast cooking, divide the broccoli up into small florets and cut the stalk into thin slices.
What Happens When You Cook This Food The broccoli stem contains a lot of cellulose and will stay firm for a long time even through the most vigorous cooking, but the cell walls of the florets are not so strongly fortified and will soften, eventually turning to mush if you cook the broccoli long enough. Like other cruciferous vegetables, broccoli contains mustard oils (isothiocyanates), natural chemicals that break down into a variety of smelly sulfur compounds (including hydrogen sulfide and ammonia) when the broccoli is heated. The reaction is more intense in aluminum pots. The longer you cook broccoli, the more smelly compounds there will be, although broccoli will never be as odorous as cabbage or cauliflower. Keeping a lid on the pot will stop the smelly molecules from floating off into the air but will also accelerate the chemical reaction that turns green broccoli olive-drab. Chlorophyll, the pigment that makes green vegetables green, is sensitive to acids. When you heat broccoli, the chlorophyll in its florets and stalk reacts chemically with acids in the broccoli or in the cooking water to form pheophytin, which is brown. The pheophytin turns cooked broccoli olive-drab or (since broccoli contains some yellow carotenes) bronze. To keep broccoli green, you must reduce the interaction between the chlorophyll and the acids. One way to do this is to cook the broccoli in a large quantity of water, so the acids will be diluted, but this increases the loss of vitamin C.* Another alternative is to leave the lid off the pot so that the hydrogen atoms can float off into the air, but this allows the smelly sulfur compounds to escape, too. The best way is probably to steam the broccoli quickly with very little water, so it holds onto its vitamin C and cooks before there is time for reac- tion between chlorophyll and hydrogen atoms to occur.
How Other Kinds of Processing Affect This Food Freezing. Frozen broccoli usually contains less vitamin C than fresh broccoli. The vitamin is lost when the broccoli is blanched to inactivate catalase and peroxidase, enzymes that would otherwise continue to ripen the broccoli in the freezer. On the other hand, according to researchers at Cornell University, blanching broccoli in a microwave oven—two cups of broccoli in three tablespoons of water for three minutes at 600 –700 watts—nearly doubles the amount of vitamin C retained. In experiments at Cornell, frozen broccoli blanched in a microwave kept 90 percent of its vitamin C, compared to 56 percent for broccoli blanched in a pot of boiling water on top of a stove.
Medical Uses and/or Benefits Protection against some cancers. Naturally occurring chemicals (indoles, isothiocyanates, glucosinolates, dithiolethiones, and phenols) in Brussels sprouts, broccoli, cabbage, cauli- flower, and other cruciferous vegetables appear to reduce the risk of some forms of cancer, perhaps by preventing the formation of carcinogens in your body or by blocking cancer- causing substances from reaching or reacting with sensitive body tissues or by inhibiting the transformation of healthy cells to malignant ones. All cruciferous vegetables contain sulforaphane, a member of a family of chemicals known as isothiocyanates. In experiments with laboratory rats, sulforaphane appears to increase the body’s production of phase-2 enzymes, naturally occurring substances that inacti- vate and help eliminate carcinogens. At the Johns Hopkins University in Baltimore, Maryland, 69 percent of the rats injected with a chemical known to cause mammary cancer developed tumors vs. only 26 percent of the rats given the carcinogenic chemical plus sulforaphane. To get a protective amount of sulforaphane from broccoli you would have to eat about two pounds a week. But in 1997, Johns Hopkins researchers discovered that broccoli seeds and three-day-old broccoli sprouts contain a compound converted to sulforaphane when the seed and sprout cells are crushed. Five grams of three-day-old sprouts contain as much sulphoraphane as 150 grams of mature broccoli. * Broccoli will lose large amounts of vitamin C if you cook it in water t hat is cold when you start. As it boils, water releases ox ygen t hat would ot her wise dest roy vitamin C, so you can cut t he vitamin loss dramat ically simply by lett ing t he water boil for 60 seconds before adding t he broccoli. Vision protection. In 2004, the Johns Hopkins researchers updated their findings on sulfora- phane to suggest that it may also protect cells in the eyes from damage due to ultraviolet light, thus reducing the risk of macular degeneration, the most common cause of age-related vision loss. Lower risk of some birth defects. Up to two or every 1,000 babies born in the United States each year may have cleft palate or a neural tube (spinal cord) defect due to their mothers’ not having gotten adequate amounts of folate during pregnancy. The current R DA for folate is 180 mcg for a woman, 200 mcg for a man, but the FDA now recommends 400 mcg for a woman who is or may become pregnant. Taking a folate supplement before becoming pregnant and continuing through the first two months of pregnancy reduces the risk of cleft palate; taking folate through the entire pregnancy reduces the risk of neural tube defects. Broccoli is a good source of folate. One raw broccoli spear has 107 mcg folate, more than 50 percent of the R DA for an adult. Possible lower risk of heart attack. In the spring of 1998, an analysis of data from the records for more than 80,000 women enrolled in the long-running Nurses’ Health Study at Harvard School of Public Health/Brigham and Women’s Hospital, in Boston, demonstrated that a diet providing more than 400 mcg folate and 3 mg vitamin B6 daily, either from food or supple- ments, might reduce a woman’s risk of heart attack by almost 50 percent. Although men were not included in the study, the results were assumed to apply to them as well. However, data from a meta-analysis published in the Journal of the American Medical Association in December 2006 called this theory into question. Researchers at Tulane Univer- sity examined the results of 12 controlled studies in which 16,958 patients with preexisting cardiovascular disease were given either folic acid supplements or placebos (“look-alike” pills with no folic acid) for at least six months. The scientists, who found no reduction in the risk of further heart disease or overall death rates among those taking folic acid, concluded that further studies will be required to ascertain whether taking folic acid supplements reduces the risk of cardiovascular disease. Possible inhibition of the herpes virus. Indoles, another group of chemicals in broccoli, may inhibit the growth of some herpes viruses. In 2003, at the 43rd annual Interscience Confer- ence on Antimicrobial Agents and Chemotherapy, in Chicago, researchers from Stockholm’s Huddinge University Hospital, the University of Virginia, and Northeastern Ohio University reported that indole-3-carbinol (I3C) in broccoli stops cells, including those of the herpes sim- plex virus, from reproducing. In tests on monkey and human cells, I3C was nearly 100 percent effective in blocking reproduction of the HSV-1 (oral and genital herpes) and HSV-2 (genital herpes), including one strain known to be resistant to the antiviral drug acyclovir (Zovirax).
Adverse Effects Associated with This Food Enlarged thyroid gland. Cruciferous vegetables, including broccoli, contain goitrin, thio- cyanate, and isothiocyanate, chemical compounds that inhibit the formation of thyroid hormones and cause the thyroid to enlarge in an attempt to produce more. These chemicals, known collectively as goitrogens, are not hazardous for healthy people who eat moderate amounts of cruciferous vegetables, but they may pose problems for people who have thyroid problems or are taking thyroid medication. False-positive test for occult blood in the stool. The guaiac slide test for hidden blood in feces relies on alphaguaiaconic acid, a chemical that turns blue in the presence of blood. Broccoli contains peroxidase, a natural chemical that also turns alphaguaiaconic acid blue and may produce a positive test in people who do not actually have blood in the stool.
Food/Drug Interactions Anticoagulants Broccoli is rich in vitamin K, the blood-clotting vitamin produced natu- rally by bacteria in the intestines. Consuming large quantities of this food may reduce the effectiveness of anticoagulants (blood thinners) such as warfarin (Coumadin). One cup of drained, boiled broccoli contains 220 mcg vitamin K, nearly four times the R DA for a healthy adult.... A Nutritional, Medical and Culinary Guide

About the Nutrients in This Food Brussels sprouts are high in dietary fiber, especially insoluble cellulose and lignan in the leaf ribs. They are also a good source of vitamin A and vitamin C. One-half cup cooked fresh brussels sprouts has three grams of dietary fiber, 1,110 IU vitamin A (48 percent of the R DA for a woman, 37 percent of the R DA for a man), 47 mcg folate (16 percent of the R DA), and 48 mg vitamin C (64 percent of the R DA for a woman, 53 percent of the R DA for a man). Brussels sprouts also contain an antinutrient, a natural chemical that splits the thiamin (vitamin B1) molecule so that it is no longer nutritionally useful. This thiamin inhibitor is inactivated by cooking.
The Most Nutritious Way to Serve This Food Fresh, lightly steamed to preserve the vitamin C and inactivate the antinutrient.
Diets That May Restrict or Exclude This Food Antiflatulence diet Low-fiber diet
Buying This Food Look for: Firm, compact heads with bright, dark-green leaves, sold loose so that you can choose the sprouts one at a time. Brussels sprouts are available all year round. Avoid: Puff y, soft sprouts with yellow or wilted leaves. The yellow carotenes in the leaves show through only when the leaves age and their green chlorophyll pigments fade. Wilting leaves and puff y, soft heads are also signs of aging. Avoid sprouts with tiny holes in the leaves through which insects have burrowed.
Storing This Food Store the brussels sprouts in the refrigerator. While they are most nutritious if used soon after harvesting, sprouts will keep their vitamins (including their heat-sensitive vitamin C) for several weeks in the refrigerator. Store the sprouts in a plastic bag or covered bowl to protect them from moisture loss.
Preparing This Food First, drop the sprouts into salted ice water to flush out any small bugs hiding inside. Next, trim them. Remove yellow leaves and leaves with dark spots or tiny holes, but keep as many of the darker, vitamin A–rich outer leaves as possible. Then, cut an X into the stem end of the sprouts to allow heat and water in so that the sprouts cook faster.
What Happens When You Cook This Food Brussels sprouts contain mustard oils (isothiocyanates), natural chemicals that break down into a variety of smelly sulfur compounds (including hydrogen sulfide and ammonia) when the sprouts are heated, a reaction that is intensified in aluminum pots. The longer you cook the sprouts, the more smelly compounds there will be. Adding a slice of bread to the cook- ing water may lessen the odor; keeping a lid on the pot will stop the smelly molecules from floating off into the air. But keeping the pot covered will also increase the chemical reaction that turns cooked brussels sprouts drab. Chlorophyll, the pigment that makes green vegetables green, is sensi- tive to acids. When you heat brussels sprouts, the chlorophyll in their green leaves reacts chemically with acids in the sprouts or in the cooking water to form pheophytin, which is brown. The pheophytin turns cooked brussels sprouts olive or, since they also contain yel- low carotenes, bronze. To keep cooked brussels sprouts green, you have to reduce the interaction between chlorophyll and acids. One way to do this is to cook the sprouts in a lot of water, so the acids will be diluted, but this increases the loss of vitamin C.* Another alternative is to leave the lid off the pot so that the hydrogen atoms can float off into the air, but this allows the smelly sulfur compounds to escape, too. The best solution is to steam the sprouts quickly in very little water, so they retain their vitamin C and cook before there is time for reaction between chlorophyll and hydrogen atoms to occur.
How Other Kinds of Processing Affect This Food Freezing. Frozen brussels sprouts contain virtually the same amounts of vitamins as fresh boiled sprouts.
Medical Uses and/or Benefits Protection against cancer. Naturally occurring chemicals (indoles, isothiocyanates, gluco- sinolates, dithiolethiones, and phenols) in brussels sprouts, broccoli, cabbage, cauliflower and other cruciferous vegetables appear to reduce the risk of some cancers, perhaps by pre- venting the formation of carcinogens in your body or by blocking cancer-causing substances from reaching or reacting with sensitive body tissues or by inhibiting the transformation of healthy cells to malignant ones. All cruciferous vegetables contain sulforaphane, a member of a family of chemicals known as isothiocyanates. In experiments with laboratory rats, sulforaphane appears to increase the body’s production of phase-2 enzymes, naturally occurring substances that inac- tivate and help eliminate carcinogens. At Johns Hopkins University in Baltimore, Maryland, 69 percent of the rats injected with a chemical known to cause mammary cancer developed tumors vs. only 26 percent of the rats given the carcinogenic chemical plus sulforaphane. In 1997, the Johns Hopkins researchers discovered that broccoli seeds and three- day-old broccoli sprouts contain a compound converted to sulforaphane when the seed and sprout cells are crushed. Five grams of three-day-old broccoli sprouts contain as much sulforaphane as 150 grams of mature broccoli. The sulforaphane levels in other cruciferous vegetables have not yet been calculated. Lower risk of some birth defects. Up to two or every 1,000 babies born in the United States each year may have cleft palate or a neural tube (spinal cord) defect due to their mothers’ not having gotten adequate amounts of folate during pregnancy. NOTE : The current R DA for folate is 180 mcg for a woman and 200 mcg for a man, but the FDA now recommends * Brussels sprouts will lose as much as 25 percent of their vitamin C if you cook them in water that is cold when you start. As it boils, water releases oxygen that would otherwise destroy vitamin C. You can cut the vitamin loss dramatically simply by letting the water boil for 60 seconds before adding the sprouts. 400 mcg for a woman who is or may become pregnant. Taking a folate supplement before becoming pregnant and continuing through the first two months of pregnancy reduces the risk of cleft palate; taking folate through the entire pregnancy reduces the risk of neural tube defects. Possible lower risk of heart attack.

About the Nutrients in This Food All cabbage has some dietary fiber food: insoluble cellulose and lignin in the ribs and structure of the leaves. Depending on the variety, it has a little vitamin A, moderate amounts of the B vitamin folate and vitamin C. One-half cup shredded raw bok choy has 0.1 g dietary fiber, 1,041 IU vitamin A (45 percent of the R DA for a woman, 35 percent of the R DA for a man), and 15.5 mg vitamin C (21 percent of the R DA for a woman, 17 percent of the R DA for a man). One-half cup shredded raw green cabbage has 0.5 g dietary fiber, 45 IU vitamin A (1.9 percent of the R DA for a woman, 1.5 percent of the R DA for a man), 15 mcg folate (4 percent of the R DA), and 11 mg vitamin C (15 percent of the R DA for a woman, 12 percent of the R DA for a man). One-half cup chopped raw red cabbage has 0.5 g dietary fiber, 7 mcg folate (2 percent of the R DA), and 20 mg vitamin C (27 percent of the R DA for a woman, 22 percent of the R DA for a man). One-half cup chopped raw savoy cabbage has one gram dietary fiber, 322 IU vitamin A (14 percent of the R DA for a woman, 11 percent of the R DA for a man), and 11 mg vitamin C (15 percent of the R DA for a woman, 12 percent of the R DA for a man). Raw red cabbage contains an antinutrient enzyme that splits the thiamin molecule so that the vitamin is no longer nutritionally useful. This thiamin in hibitor is inactivated by cooking.
The Most Nutritious Way to Serve This Food Raw or lightly steamed to protect the vitamin C.
Diets That May Restrict or Exclude This Food Antiflatulence diet Low-fiber diet
Buying This Food Look for: Cabbages that feel heavy for their size. The leaves should be tightly closed and attached tightly at the stem end. The outer leaves on a savoy cabbage may curl back from the head, but the center leaves should still be relatively tightly closed. Also look for green cabbages that still have their dark-green, vitamin-rich outer leaves. Avoid: Green and savoy cabbage with yellow or wilted leaves. The yellow carotene pig- ments show through only when the cabbage has aged and its green chlorophyll pigments have faded. Wilted leaves mean a loss of moisture and vitamins.
Storing This Food Handle cabbage gently; bruising tears cells and activates ascorbic acid oxidase, an enzyme in the leaves that hastens the destruction of vitamin C. Store cabbage in a cool, dark place, preferably a refrigerator. In cold storage, cabbage can retain as much as 75 percent of its vitamin C for as long as six months. Cover the cabbage to keep it from drying out and losing vitamin A.
Preparing This Food Do not slice the cabbage until you are ready to use it; slicing tears cabbage cells and releases the enzyme that hastens the oxidation and destruction of vitamin C. If you plan to serve cooked green or red cabbage in wedges, don’t cut out the inner core that hold the leaves together. To separate the leaves for stuffing, immerse the entire head in boiling water for a few minutes, then lift it out and let it drain until it is cool enough to handle comfortably. The leaves should pull away easily. If not, put the cabbage back into the hot water for a few minutes.
What Happens When You Cook This Food Cabbage contains mustard oils (isothiocyanates) that break down into a variet y of smelly sulfur compounds (including hydrogen sulfide and ammon ia) when the cabbage is heated, a reaction that occurs more strongly in aluminum pots. The longer you cook the cabbage, the more smelly the compounds will be. Adding a slice of bread to the cooking water may lessen the odor. Keeping a lid on the pot will stop the smelly molecules from floating off into the air, but it will also accelerate the chemical reaction that turns cooked green cabbage drab. Chlorophyll, the pigment that makes green vegetables green, is sensitive to acids. When you heat green cabbage, the chlorophyll in its leaves reacts chemically with acids in the cabbage or in the cooking water to form pheophytin, which is brown. The pheophytin gives the cooked cabbage its olive color. To keep cooked green cabbage green, you have to reduce the interaction between the chlorophyll and the acids. One way to do this is to cook the cabbage in a large quantity of water, so the acids will be diluted, but this increases the loss of vitamin C.* Another alternative is to leave the lid off the pot so that the volatile acids can float off into the air, but this allows the smelly sulfur compounds to escape too. The best way may be to steam the cabbage ver y quickly in ver y little water so that it keeps its vitamin C and cooks before there is time for the chlorophyll/acid reaction to occur. Red cabbage is colored with red anthocyanins, pigments that turn redder in acids (lemon juice, vinegar) and blue purple in bases (alkaline chemicals such as baking soda). To keep the cabbage red, make sweet-and-sour cabbage. But be careful not to make it in an iron or aluminum pot, since vinegar (which contains tannins) will react with these metals to create dark pigments that discolor both the pot and the vegetable. Glass, stainless-steel, or enameled pots do not produce this reaction.
How Other Kinds of Processing Affect This Food Pickling. Sauerkraut is a fermented and pickled produce made by immersing cabbage in a salt solution strong enough to kill off pathological bacteria but allow beneficial ones to sur- vive, breaking down proteins in the cabbage and producing the acid that gives sauerkraut its distinctive flavor. Sauerkraut contains more than 37 times as much sodium as fresh cabbage (661 mg sodium/100 grams canned sauerkraut with liquid) but only one third the vitamin C and one-seventh the vitamin A. * According to USDA, if you cook t hree cups of cabbage in one cup of water you will lose only 10 percent of t he vitamin C; reverse t he rat io to four t imes as much water as cabbage and you will lose about 50 percent of t he vitamin C. Cabbage will lose as much as 25 percent of its vitamin C if you cook it in water t hat is cold when you start. As it boils, water releases ox ygen t hat would ot her wise dest roy vitamin C, so you can cut t he vitamin loss dramat ically simply by lett ing t he water boil for 60 seconds before adding t he cabbage.
Medical Uses and/or Benefits Protection against certain cancers. Naturally occurring chemicals (indoles, isothiocyanates, glucosinolates, dithiolethiones, and phenols) in cabbage, brussels sprouts, broccoli, cauli- flower, and other cruciferous vegetables appear to reduce the risk of some cancers, perhaps by preventing the formation of carcinogens in your body or by blocking cancer-causing substances from reaching or reacting with sensitive body tissues or by inhibiting the trans- formation of healthy cells to malignant ones.

Consuming large quantities of this food may reduce the effectiveness of anticoagulants (blood thinners) such as warfarin (Coumadin). One cup of shredded common green cabbage contains 163 mcg vitamin K, nearly three times the R DA for a healthy adult; one cup of drained boiled common green cabbage contains 73 mcg vita- min K, slightly more than the R DA for a healthy adult. Monoamine oxidase (MAO) inhibitors. Monoamine oxidase inhibitors are drugs used to treat depression. They inactivate naturally occurring enzymes in your body that metabolize tyra- mine, a substance found in many fermented or aged foods. Tyramine constricts blood vessels and increases blood pressure. If you eat a food such as sauerkraut which is high in tyramine while you are taking an M AO inhibitor, you cannot effectively eliminate the tyramine from your body. The result may be a hypertensive crisis.... A Nutritional, Medical and Culinary Guide
The operation is usually performed through a low, horizontal ‘bikini line’ incision. A general anaesthetic in a heavily pregnant woman carries increased risks, so the operation is often performed under regional – epidural or spinal – ANAESTHESIA. This also allows the mother to see her baby as soon as it is born, and the baby is not exposed to agents used for general anaesthesia. If a general anaesthetic is needed (usually in an emergency), exposure to these agents may make the baby drowsy for some time afterwards.
Another problem with delivery by Caesarean section is, of course, that the mother must recover from the operation whilst coping with the demands of a small baby. (See PREGNANCY AND LABOUR.)... Medical Dictionary
Calcium is a most important element in diet; the chief sources of it are milk and cheese. Calcium is especially needed by the growing child and the pregnant and nursing mother. The uptake of calcium by the baby is helped by vitamin D (see APPENDIX 5: VITAMINS). A de?ciency of calcium may cause TETANY, and an excess may result in the development of CALCULI (stones) in the KIDNEYS or gallbladder (see LIVER).
The recommended daily intakes of calcium are: 500 mg for children, 700 mg for adolescents, 500–900 mg for adults and 1,200 mg for pregnant or nursing mothers.... Medical Dictionary
Symptoms. A small lump comes to light while washing, a discharge from the nipple, change in nipple size and colour, irregular contour of the breast surface. Though tissue change is likely to be a cyst, speedy diagnosis and treatment are necessary. Some hospital physicians and surgeons are known to view favourably supportive herbal aids, and do not always think in terms of radical mastectomy. Dr Finlay Ellingwood, Chicago physician (1916) cured a case by injection of one dram Echinacea root extract twice a week into the surrounding tissues.
The condition is believed to be due to a number of causes including suppression of ovulation and oestrogen secretion in pregnant and lactating women. A high fat diet is suspected of interference with the production of oestrogen. Some women are constitutionally disposed to the condition which may be triggered by trauma or emotional shock. Increase in incidence in older women has been linked with excessive sugar consumption. “Consumption overwhelms the pancreas which has to ‘push it out’ to all parts of the body (when broken down by the digestive process) whether they need it or not. The vital organs are rationed according to their requirements of nutrients from the diet. What is left over has to ‘go into store elsewhere’. And the breast is forced to take its share and store it. If it gets too much, for too long, it may rebel!” (Stephen Seely, Department of Bacteriology and Virology, Manchester)
“Women who nurse their babies less than one month are at an increased risk for breast cancer. The longer a woman breast-feeds – no matter what her age – the more the risk decreases. (Marion Tompson, co-founder, The La Leche League, in the American Journal of Epidemiology)
Lactation reduces the risk of pre-menopausal breast cancer. (Newcomb P.A. et al New England Journal of Medicine, 330 1994)
There is currently no treatment to cure metastatic breast cancer. In spite of chemotherapy, surgery and radiotherapy survival rate has not diminished. Herbs not only have a palliative effect but, through their action on hormone function offer a positive contribution towards overcoming the condition. Their activity has been widely recorded in medical literature. Unlike cytotoxic drugs, few have been known to cause alopecia, nausea, vomiting or inflammation of the stomach.
Treatment by a general medical practitioner or oncologist.
Special investigations. Low radiation X-ray mammography to confirm diagnosis. Test for detection of oestrogen receptor protein.
Treatment. Surgery may be necessary. Some patients may opt out from strong personal conviction, choosing a rigid self-disciplined approach – the Gentle Way. Every effort is made to build up the body’s natural defences (immune system).
An older generation of herbalists believed tissue change could follow a bruise on the breast, which should not be neglected but immediately painted with Tincture Arnica or Tincture Bellis perennis.

Meat-free diet. In a study of 75 adolescent girls, vegetarians were found to have higher levels of a hormone that women suffering from breast cancer often lack. (Cancer Research) Supplements. Daily. Chromium. Selenium (600mcg). Zinc chelate (100mg morning and evening). Beta carotene. “Low levels of Selenium and Vitamins A and E are shown in breast cancer cases.” (British Journal of Cancer 49: 321-324, 1984).
Vitamins A and D inhibit virus penetration in healthy cell walls. Multivitamin combinations should not include Vitamin B12, production of which in the body is much increased in cancerous conditions. Vitamins B-complex and C especially required.
Note: A link between sugar consumption and breast cancer has been reported by some authorities who suggest that countries at the top of the mortality table are the highest also in sugar consumption; the operative factor believed to be insulin.
Screening. Breast screening should be annual from the age of forty.

Each year around 50 people in the United Kingdom are reported as dying from carbon monoxide poisoning, and experts have suggested that as many as 25,000 people a year are exposed to its effects within the home, but most cases are unrecognised, unreported and untreated, even though victims may suffer from long-term effects. This is regrettable, given that Napoleon’s surgeon, Larrey, recognised in the 18th century that soldiers were being poisoned by carbon monoxide when billeted in huts heated by woodburning stoves. In the USA it is estimated that 40,000 people a year attend emergency departments suffering from carbon monoxide poisoning. So prevention is clearly an important element in dealing with what is sometimes termed the ‘silent killer’. Safer designs of houses and heating systems, as well as wider public education on the dangers of carbon monoxide and its sources, are important.
Clinical effects of acute exposure resemble those of atmospheric HYPOXIA. Tissues and organs with high oxygen consumption are affected to a great extent. Common effects include headaches, weakness, fatigue, ?ushing, nausea, vomiting, irritability, dizziness, drowsiness, disorientation, incoordination, visual disturbances, TACHYCARDIA and HYPERVENTILATION. In severe cases drowsiness may progress rapidly to COMA. There may also be metabolic ACIDOSIS, HYPOKALAEMIA, CONVULSIONS, HYPOTENSION, respiratory depression, ECG changes and cardiovascular collapse. Cerebral OEDEMA is common and will lead to severe brain damage and focal neurological signs. Signi?cant abnormalities on physical examination include impaired short-term memory, abnormal Rhomberg’s test (standing unsupported with eyes closed) and unsteadiness of gait including heel-toe walking. Any one of these signs would classify the episode as severe. Victims’ skin may be coloured pink, though this is very rarely seen even in severe incidents. The venous blood may look ‘arterial’. Patients recovering from acute CO poisoning may suffer neurological sequelae including TREMOR, personality changes, memory impairment, visual loss, inability to concentrate and PARKINSONISM. Chronic low-level exposures may result in nausea, fatigue, headache, confusion, VOMITING, DIARRHOEA, abdominal pain and general malaise. They are often misdiagnosed as in?uenza or food poisoning.
First-aid treatment is to remove the victim from the source of exposure, ensure an e?ective airway and give 100-per-cent oxygen by tight-?tting mask. In hospital, management is largely suppportive, with oxygen administration. A blood sample for COHb level determination should be taken as soon as practicable and, if possible, before oxygen is given. Ideally, oxygen therapy should continue until the COHb level falls below 5 per cent. Patients with any history of unconsciousness, a COHb level greater than 20 per cent on arrival, any neurological signs, any cardiac arrhythmias or anyone who is pregnant should be referred for an expert opinion about possible treatment with hyperbaric oxygen, though this remains a controversial therapy. Hyperbaric oxygen therapy shortens the half-life of COHb, increases plasma oxygen transport and reverses the clinical effects resulting from acute exposures. Carbon monoxide is also an environmental poison and a component of cigarette smoke. Normal body COHb levels due to ENDOGENOUS CO production are 0.4 to
0.7 per cent. Non-smokers in urban areas may have level of 1–2 per cent as a result of environmental exposure. Smokers may have a COHb level of 5 to 6 per cent.... Medical Dictionary

About the Nutrients in This Food Cheese making begins when Lactobacilli and/or Streptococci bacteria are added to milk. The bacteria digest lactose (milk sugar) and release lactic acid, which coagulates casein (milk protein) into curds. Rennet (gastric enzymes extracted from the stomach of calves) is added, and the mixture is put aside to set. The longer the curds are left to set, the firmer the cheese will be. When the curds are properly firm, they are pressed to squeeze out the whey (liquid) and cooked. Cooking evaporates even more liquid and makes the cheese even firmer.* At this point, the product is “fresh” or “green” cheese: cottage cheese, cream cheese, farmer cheese. Making “ripe” cheese requires the addition of salt to pull out more moisture and specific organisms, such as Penicil- lium roquefort for Roquefort cheese, blue cheese, and Stilton, or Penicillium cambembert for Camembert and Brie. The nutritional value of cheese is similar to the milk from which it is made. All cheese is a good source of high quality proteins with sufficient amounts of all the essential amino acids. Cheese is low to high in fat, mod- erate to high in cholesterol. * Natural cheese is cheese made direct ly from milk. Processed cheese is natural cheese melted and combined wit h emulsifiers. Pasteurized process cheese foods contain ingredients t hat allow t hem to spread smoot hly; t hey are lower in fat and higher in moisture t han processed cheese. Cholesterol and Saturated Fat Content of Selected Cheeses Mozzarella Source: USDA, Nutritive Value of Foods, Home and Garden Bullet in No. 72 (USDA, 1989). All cheeses, except cottage cheese, are good sources of vitamin A. Orange and yellow cheeses are colored with carotenoid pigments, including bixin (the carotenoid pigment in annatto) and synthetic beta-carotene. Hard cheeses are an excellent source of calcium; softer cheeses are a good source; cream cheese and cottage cheese are poor sources. The R DA for calcium is 1,000 mg for a woman, 1,200 mg for a man, and 1,500 mg for an older woman who is not on hormone- replacement therapy. All cheese, unless otherwise labeled, is high in sodium.

The Most Nutritious Way to Serve This Food With grains, bread, noodles, beans, nuts, or vegetables to add the essential amino acids miss- ing from these foods, “complete” their proteins, and make them more nutritionally valuable.
Diets That May Restrict or Exclude This Food Antiflatulence diet Controlled-fat, low-cholesterol diet Lactose- and galactose-free diet (lactose, a disaccharide [double sugar] is composed of one unit of galactose and one unit of glucose) Low-calcium diet (for patients with kidney disease) Sucrose-free diet (processed cheese)
Buying This Food Look for: Cheese stored in a refrigerated case. Check the date on the package. Avoid: Any cheese with mold that is not an integral part of the food.
Storing This Food Refrigerate all cheese except unopened canned cheeses (such as Camembert in tins) or grated cheeses treated with preservatives and labeled to show that they can be kept outside the refrigerator. Some sealed packages of processed cheeses can be stored at room temperature but must be refrigerated once the package is opened. Wrap cheeses tightly to protect them from contamination by other microorganisms in the air and to keep them from drying out. Well-wrapped, refrigerated hard cheeses that have not been cut or sliced will keep for up to six months; sliced hard cheeses will keep for about two weeks. Soft cheeses (cottage cheese, ricotta, cream cheese, and Neufchatel) should be used within five to seven days. Use all packaged or processed cheeses by the date stamped on the package. Throw out moldy cheese (unless the mold is an integral part of the cheese, as with blue cheese or Stilton).
Preparing This Food To grate cheese, chill the cheese so it won’t stick to the grater. The molecules that give cheese its taste and aroma are largely immobilized when the cheese is cold. When serving cheese with fruit or crackers, bring it to room temperature to activate these molecules.
What Happens When You Cook This Food Heat changes the structure of proteins. The molecules are denatured, which means that they may be broken into smaller fragments or change shape or clump together. All of these changes may force moisture out of the protein tissue, which is why overcooked cheese is often stringy. Whey proteins, which do not clump or string at low temperatures, contain the sulfur atoms that give hot or burned cheese an unpleasant “cooked” odor. To avoid both strings and an unpleasant odor, add cheese to sauces at the last minute and cook just long enough to melt the cheese.
How Other Kinds of Processing Affect This Food Freezing. All cheese loses moisture when frozen, so semisoft cheeses will freeze and thaw better than hard cheeses, which may be crumbly when defrosted. Drying. The less moisture cheese contains, the less able it is to support the growth of organ- isms like mold. Dried cheeses keep significantly longer than ordinary cheeses.
Medical Uses and/or Benefits To strengthen bones and reduce age-related loss of bone density. High-calcium foods protect bone density. The current recommended dietary allowance (R DA) for calcium is still 800 mg for adults 25 and older, but a 1984 National Institutes of Health (NIH) Conference advisory stated that lifelong protection for bones requires an R DA of 1,000 mg for healthy men and women age 25 to 50 ; 1,000 mg for older women using hormone replacement therapy; and 1,500 mg for older women who are not using hormones, and these recommendations have been confirmed in a 1994 NIH Consensus Statement on optimal calcium intake. A diet with adequate amounts of calcium-rich foods helps protect bone density. Low-fat and no-fat cheeses provide calcium without excess fat and cholesterol. Protection against tooth decay. Studies at the University of Iowa (Iowa City) Dental School confirm that a wide variety of cheeses, including aged cheddar, Edam, Gouda, Monterey Jack, Muenster, mozzarella, Port Salut, Roquefort, Romano, Stilton, Swiss, and Tilsit—limit the tooth decay ordinarily expected when sugar becomes trapped in plaque, the sticky film on tooth surfaces where cavity-causing bacteria flourish. In a related experiment using only cheddar cheese, people who ate cheddar four times a day over a two-week period showed a 20 percent buildup of strengthening minerals on the surface of synthetic toothlike material attached to the root surfaces of natural teeth. Protection against periodontal disease. A report in the January 2008 issue of the Journal of Periodontology suggests that consuming adequate amounts of dairy products may reduce the risk of developing periodontal disease. Examining the dental health of 942 subjects ages 40 to 79, researchers at Kyushu University, in Japan, discovered that those whose diets regularly included two ounces (55 g) of foods containing lactic acid (milk, cheese, and yogurt) were significantly less likely to have deep “pockets” (loss of attachment of tooth to gum) than those who consumed fewer dairy products.
Adverse Effects Associated with This Food Increased risk of heart disease. Like other foods from animals, cheese is a source of choles- terol and saturated fats, which increase the amount of cholesterol circulating in your blood and raise your risk of heart disease. To reduce the risk of heart disease, the USDA /Health and Human Services Dietary Guidelines for Americans recommends limiting the amount of cholesterol in your diet to no more than 300 mg a day. The guidelines also recommend limit- ing the amount of fat you consume to no more than 30 percent of your total calories, while holding your consumption of saturated fats to more than 10 percent of your total calories (the calories from saturated fats are counted as part of the total calories from fat). Food poisoning. Cheese made from raw (unpasteurized) milk may contain hazardous microorganisms, including Salmonella and Listeria. Salmonella causes serious gastric upset; Lis- teria, a flulike infection, encephalitis, or blood infection. Both may be life-threatening to the very young, the very old, pregnant women, and those whose immune systems are weakened either by illness (such as AIDS) or drugs (such as cancer chemotherapy). In 1998, the Federal Centers for Disease Control (CDC) released data identif ying Listeria as the cause of nearly half the reported deaths from food poisoning. Allergy to milk proteins. Milk is one of the foods most frequently implicated as a cause of allergic reactions, particularly upset stomach. However, in many cases the reaction is not a true allergy but the result of lactose intolerance (see below). Lactose intolerance. Lactose intolerance—the inability to digest the sugar in milk—is an inherited metabolic deficiency that affects two thirds of all adults, including 90 to 95 percent of all Orientals, 70 to 75 percent of all blacks, and 6 to 8 percent of Caucasians. These people do not have sufficient amounts of lactase, the enzyme that breaks the disaccharide lactose into its easily digested components, galactose and glucose. When they drink milk, the undi- gested sugar is fermented by bacteria in the gut, causing bloating, diarrhea, flatulence, and intestinal discomfort. Some milk is now sold with added lactase to digest the lactose and make the milk usable for lactase-deficient people. In making cheese, most of the lactose in milk is broken down into glucose and galactose. There is very little lactose in cheeses other than the fresh ones—cottage cheese, cream cheese, and farmer cheese. Galactosemia. Galactosemia is an inherited metabolic disorder in which the body lacks the enzymes needed to metabolize galactose, a component of lactose. Galactosemia is a reces- sive trait; you must receive the gene from both parents to develop the condition. Babies born with galactosemia will fail to thrive and may develop brain damage or cataracts if they are given milk. To prevent this, children with galactosemia are usually kept on a protective milk- free diet for several years, until their bodies have developed alternative pathways by which to metabolize galactose. Pregnant women who are known carriers of galactosemia may be advised to give up milk and milk products while pregnant lest the unmetabolized galactose in their bodies cause brain damage to the fetus (damage not detectable by amniocentesis). Genetic counseling is available to identif y galactosemia carriers and assess their chances of producing a baby with the disorder. Penicillin sensitivity. People who experience a sensitivity reaction the first time they take penicillin may have been sensitized by exposure to the Penicillium molds in the environment, including the Penicillium molds used to make brie, blue, camembert, roquefort, Stilton, and other “blue” cheeses.
Food/Drug Interactions Tetracycline. The calcium ions in milk products, including cheese, bind tetracyclines into insoluble compounds. If you take tetracyclines with cheese, your body may not be able to absorb and use the drug efficiently. Monoamine oxidase (MAO) inhibitors. Monoamine oxidase inhibitors are drugs used to treat depression. They inactivate naturally occurring enzymes in your body that metabolize tyra- mine, a substance found in many fermented or aged foods. Tyramine constricts blood ves- sels and increases blood pressure. If you eat a food such as aged or fermented cheese which is high in tyramine while you are taking an M AO inhibitor, your body may not be able to eliminate the tyramine. The result may be a hypertensive crisis.

False-positive test for pheochromocytoma. Pheochromocytomas (tumors of the adrenal glands) secrete adrenalin that is converted by the body to vanillyl-mandelic acid ( VM A) and excreted in the urine. Tests for this tumor measure the level of VM A in the urine. Since cheese contains VM A, taking the test after eating cheese may result in a false-positive result. Ordinarily, cheese is prohibited for at least 72 hours before this diagnostic test.... A Nutritional, Medical and Culinary Guide

Incubation period varies from a few hours to ?ve days. Watery diarrhoea may be torrential and the resultant dehydration and electrolyte imbalance, complicated by cardiac failure, commonly causes death. The victim’s skin elasticity is lost, the eyes are sunken, and the radial pulse may be barely perceptible. Urine production may be completely suppressed. Diagnosis is by detection of V. cholerae in a faecal sample. Treatment consists of rapid rehydration. Whereas the intravenous route may be required in a severe case, in the vast majority of patients oral rehydration (using an appropriate solution containing sodium chloride, glucose, sodium bicarbonate, and potassium) gives satisfactory results. Proprietary rehydration ?uids do not always contain adequate sodium for rehydration in a severe case. ANTIBIOTICS, for example, tetracycline and doxycycline, reduce the period during which V. cholerae is excreted (in children and pregnant women, furazolidone is safer); in an epidemic, rapid resistance to these, and other antibiotics, has been clearly demonstrated. Prevention consists of improving public health infrastructure – in particular, the quality of drinking water. When supplies of the latter are satisfactory, the infection fails to thrive. Though there have recently been large epidemics of cholera in much of South America and parts of central Africa and the Indian subcontinent, the risk of tourists and travellers contracting the disease is low if they take simple precautions. These include eating safe food (avoid raw or undercooked seafood, and wash vegetables in clean water) and drinking clean water. There is no cholera vaccine at present available in the UK as it provides little protection and cannot control spread of the disease. Those travelling to countries where it exists should pay scrupulous attention to food and water cleanliness and to personal hygiene.... Medicinal Plants Glossary

Barrier methods These involve a physical barrier which prevents sperm (see SPERMATOZOON) from reaching the cervix (see CERVIX UTERI). Barrier methods reduce the risk of spreading sexually transmitted diseases, and the sheath is the best protection against HIV infection (see AIDS/HIV) for sexually active people. The e?ciency of barrier methods is improved if they are used in conjunction with a spermicidal foam or jelly, but care is needed to ensure that the preparation chosen does not damage the rubber barrier or cause an allergic reaction in the users. CONDOM OR SHEATH This is the most commonly used barrier contraceptive. It consists of a rubber sheath which is placed over the erect penis before intromission and removed after ejaculation. The failure rate, if properly used, is about 4 per cent. DIAPHRAGM OR CAP A rubber dome that is inserted into the vagina before intercourse and ?ts snugly over the cervix. It should be used with an appropriate spermicide and is removed six hours after intercourse. A woman must be measured to ensure that she is supplied with the correct size of diaphragm, and the ?t should be checked annually or after more than about 7 lbs. change in weight. The failure rate, if properly used, is about 2 per cent.
Non-barrier methods These do not provide a physical barrier between sperm and cervix and so do not protect against sexually transmitted diseases, including HIV. COITUS INTERRUPTUS This involves the man’s withdrawing his penis from the vagina before ejaculation. Because some sperm may leak before full ejaculation, the method is not very reliable. SAFE PERIOD This involves avoiding intercourse around the time when the woman ovulates and is at risk of pregnancy. The safe times can be predicted using temperature charts to identify the rise in temperature before ovulation, or by careful assessment of the quality of the cervical mucus. This method works best if the woman has regular menstrual cycles. If used carefully it can be very e?ective but requires a highly disciplined couple to succeed. It is approved by the Catholic church.
SPERMICIDAL GELS, CREAMS, PESSARIES, ETC.
These are supposed to prevent pregnancy by killing sperm before they reach the cervix, but they are unreliable and should be used only in conjunction with a barrier method.
INTRAUTERINE CONTRACEPTIVE DEVICE (COIL) This is a small metal or plastic shape, placed inside the uterus, which prevents pregnancy by disrupting implantation. Some people regard it as a form of abortion, so it is not acceptable to all religious groups. There is a risk of pelvic infection and eventual infertility in women who have used coils, and in many countries their use has declined substantially. Coils must be inserted by a specially trained health worker, but once in place they permit intercourse at any time with no prior planning. Increased pain and bleeding may be caused during menstruation. If severe, such symptoms may indicate that the coil is incorrectly sited, and that its position should be checked. HORMONAL METHODS Steroid hormones have dominated contraceptive developments during the past 40 years, with more than 200 million women worldwide taking or having taken ‘the pill’. In the past 20 years, new developments have included modifying existing methods and devising more e?ective ways of delivering the drugs, such as implants and hormone-releasing devices in the uterus. Established hormonal contraception includes the combined oestrogen and progesterone and progesterone-only contraceptive pills, as well as longer-acting depot preparations. They modify the woman’s hormonal environment and prevent pregnancy by disrupting various stages of the menstrual cycle, especially ovulation. The combined oestrogen and progesterone pills are very e?ective and are the most popular form of contraception. Biphasic and triphasic pills contain di?erent quantities of oestrogen and progesterone taken in two or three phases of the menstrual cycle. A wide range of preparations is available and the British National Formulary contains details of the commonly used varieties.
The main side-e?ect is an increased risk of cardiovascular disease. The lowest possible dose of oestrogen should be used, and many preparations are phasic, with the dose of oestrogen varying with the time of the cycle. The progesterone-only, or ‘mini’, pill does not contain any oestrogen and must be taken at the same time every day. It is not as e?ective as the combined pill, but failure rates of less than 1-per-100 woman years can be achieved. It has few serious side-effects, but may cause menstrual irregularities. It is suitable for use by mothers who are breast feeding.
Depot preparations include intramuscular injections, subcutaneous implants, and intravaginal rings. They are useful in cases where the woman cannot be relied on to take a pill regularly but needs e?ective contraception. Their main side-e?ect is their prolonged action, which means that users cannot suddenly decide that they would like to become pregnant. Skin patches containing a contraceptive that is absorbed through the skin have recently been launched.
HORMONAL CONTRACEPTION FOR MEN There is a growing demand by men worldwide for hormonal contraception. Development of a ‘male pill’, however, has been slow because of the potentially dangerous side-effects of using high doses of TESTOSTERONE (the male hormone) to suppress spermatogenesis. Progress in research to develop a suitable ANDROGEN-based combination product is promising, including the possibility of long-term STEROID implants. STERILISATION See also STERILISATION – Reproductive sterilisation. The operation is easier and safer to perform on men than on women. Although sterilisation can sometimes be reversed, this cannot be guaranteed and couples should be counselled in advance that the method is irreversible. There is a small but definite failure rate with sterilisation, and this should also be made clear before the operation is performed. POSTCOITAL CONTRACEPTION Also known as emergency contraception or the ‘morning after pill’, postcoital contraception can be e?ected by two di?erent hormonal methods. Levonorgesterol (a synthetic hormone similar to the natural female sex hormone PROGESTERONE) can be used alone, with one pill being taken within 72 hours of unprotected intercourse, but preferably as soon as possible, and a second one 12 hours after the ?rst. Alternatively, a combined preparation comprising ETHINYLESTRADIOL and levonorgesterol can be taken, also within 72 hours of unprotected intercourse. The single constituent pill has fewer side-effects than the combined version. Neither version should be taken by women with severe liver disease or acute PORPHYRIAS, but the ethinylestradiol/levonorgesterol combination is unsuitable for women with a history of THROMBOSIS.
In the UK the law allows women over the age of 16 to buy the morning-after pill ‘over the counter’ from a registered pharmacist.... Medical Dictionary

Unsaturated fatty acids, as in vegetable oils, should replace animal fats (saturated fatty acids) that increase deposits of cholesterol on the inner coat of arteries and encourage hardening. Vegetable oils contain lecithin – a homogeniser which thins and separates the cholesterol, sweeping it along through the bloodstream and preventing deposits to form on walls of the arteries.
A study on the European population has shown a strong link between oily fish consumption and a reduced risk of heart disease. Populations that eat a lot of fish, such as Greenland Eskimos (about 400g a day) and Japanese fishermen (about 200g a day) have low rates of heart disease.
Another study, by the Leiden University of the Netherlands, has found that men who ate more than 30g of fish per day were less than half as likely to die from coronary heart disease as those who ate no fish. A diet high in fish lowers plasma cholesterol, triglyceride and very low density lipoprotein levels and is of value in the treatment of hyperlipidaemia (abnormally high concentration of fats in the blood).

In the United States, the proof of an alcoholic beverage is defined as twice its alcohol content by volume: a beverage with 20 percent alcohol by volume is 40 proof. This is high enough for most wines, but not high enough for most whiskies, gins, vodkas, rums, brandies, and tequilas. To reach the concentra- tion of alcohol required in these beverages, the fermented sugars are heated and distilled. Ethyl alcohol (the alcohol in beer, wine, and spirits) boils at a lower temperature than water. When the fermented sugars are heated, the ethyl alcohol escapes from the distillation vat and condenses in tubes leading from the vat to a collection vessel. The clear liquid that collects in this vessel is called distilled spirits or, more technically, grain neutral spirits. Gins, whiskies, cordials, and many vodkas are made with spirits American whiskeys (which include bourbon, rye, and distilled from grains. blended whiskeys) and Canadian, Irish, and Scotch whiskies are all made from spirits aged in wood barrels. They get their flavor from the grains and their color from the barrels. (Some whiskies are also colored with caramel.) Vodka is made from spirits distilled and filtered to remove all flavor. By law, vodkas made in America must be made with spirits distilled from grains. Imported vodkas may be made with spirits distilled either from grains or potatoes and may contain additional flavoring agents such as citric acid or pepper. Aquavit, for example, is essentially vodka flavored with caraway seeds. Gin is a clear spirit flavored with an infusion of juniper berries and other herbs (botanicals). Cordials (also called liqueurs) and schnapps are flavored spirits; most are sweetened with added sugar. Some cordials contain cream. Rum is made with spirits distilled from sugar cane (molasses). Tequila is made with spirits distilled from the blue agave plant. Brandies are made with spirits distilled from fruit. (Arma- gnac and cognac are distilled from fermented grapes, calvados and applejack from fermented apples, kirsch from fermented cherries, slivovitz from fermented plums.) Unless they contain added sugar or cream, spirits have no nutrients other than alcohol. Unlike food, which has to be metabolized before your body can use it for energy, alcohol can be absorbed into the blood-stream directly from the gastrointestinal tract. Ethyl alcohol provides 7 calories per gram.
The Most Nutritious Way to Serve This Food The USDA /Health and Human Services Dietary Guidelines for Americans defines one drink as 12 ounces of beer, five ounces of wine, or 1.25 ounces of distilled spirits, and “moderate drinking” as two drinks a day for a man, one drink a day for a woman.
Diets That May Restrict or Exclude This Food Bland diet Lactose-free diet (cream cordials made with cream or milk) Low-purine (antigout) diet
Buying This Food Look for: Tightly sealed bottles stored out of direct sunlight, whose energy might disrupt the structure of molecules in the beverage and alter its flavor. Choose spirits sold only by licensed dealers. Products sold in these stores are manufac- tured under the strict supervision of the federal government.
Storing This Food Store sealed or opened bottles of spirits in a cool, dark cabinet.
Preparing This Food All spirits except unflavored vodkas contain volatile molecules that give the beverage its characteristic taste and smell. Warming the liquid excites these molecules and intensifies the flavor and aroma, which is the reason we serve brandy in a round glass with a narrower top that captures the aromatic molecules as they rise toward the air when we warm the glass by holding it in our hands. Whiskies, too, though traditionally served with ice in America, will have a more intense flavor and aroma if served at room temperature.
What Happens When You Cook This Food The heat of cooking evaporates the alcohol in spirits but leaves the flavoring intact. Like other alcoholic beverages, spirits should be added to a recipe near the end of the cooking time to preserve the flavor while cooking away any alcohol bite. Alcohol is an acid. If you cook it in an aluminum or iron pot, it will combine with metal ions to form dark compounds that discolor the pot and the food you are cooking. Any recipe made with spirits should be prepared in an enameled, glass, or stainless-steel pot.
Medical Uses and/or Benefits Reduced risk of heart attack. Data from the American Cancer Society’s Cancer Prevention Study 1, a 12-year survey of more than 1 million Americans in 25 states, shows that men who take one drink a day have a 21 percent lower risk of heart attack and a 22 percent lower risk of stroke than men who do not drink at all. Women who have up to one drink a day also reduce their risk of heart attack. Numerous later studies have confirmed these findings. Lower cholesterol levels. Beverage alcohol decreases the body’s production and storage of low density lipoproteins (LDLs), the protein and fat particles that carry cholesterol into your arteries. As a result, people who drink moderately tend to have lower cholesterol levels and higher levels of high density lipoproteins (HDLs), the fat and protein particles that carry cholesterol out of the body. Numerous later studies have confirmed these findings. Lower risk of stroke. In January 1999, the results of a 677-person study published by researchers at New York Presbyterian Hospital-Columbia University showed that moderate alcohol consumption reduces the risk of stroke due to a blood clot in the brain among older people (average age: 70). How alcohol prevents stroke is still unknown, but it is clear that moderate use is a key. Heavy drinkers (those who consume more than seven drinks a day) have a higher risk of stroke. People who once drank heavily, but cut their consumption to moderate levels, reduce their risk of stroke. Stimulating the appetite. Alcoholic beverages stimulate the production of saliva and the gastric acids that cause the stomach contractions we call hunger pangs. Moderate amounts of alcoholic beverages, which may help stimulate appetite, are often prescribed for geriatric patients, convalescents, and people who do not have ulcers or other chronic gastric problems that might be exacerbated by the alcohol. Dilation of blood vessels. Alcoholic beverages dilate the tiny blood vessels just under the skin, bringing blood up to the surface. That’s why moderate amounts of alcoholic beverages (0.2–1 gram per kilogram of body weight, or two ounces of whiskey for a 150-pound adult) temporarily warm the drinker. But the warm blood that flows up to the surface of the skin will cool down there, making you even colder when it circulates back into the center of your body. Then an alcohol flush will make you perspire, so you lose more heat. Excessive amounts of beverage alcohol may depress the mechanism that regulates body temperature.
Adverse Effects Associated with This Food Alcoholism. Alcoholism is an addiction disease, the inability to control one’s alcohol consumption. It is a potentially life-threatening condition, with a higher risk of death by accident, suicide, malnutrition, or acute alcohol poisoning, a toxic reaction that kills by para- lyzing body organs, including the heart. Fetal alcohol syndrome. Fetal alcohol syndrome is a specific pattern of birth defects—low birth weight, heart defects, facial malformations, learning disabilities, and mental retarda- tion—first recognized in a study of babies born to alcoholic women who consumed more than six drinks a day while pregnant. Subsequent research has found a consistent pattern of milder defects in babies born to women who drink three to four drinks a day or five drinks on any one occasion while pregnant. To date there is no evidence of a consistent pattern of birth defects in babies born to women who consume less than one drink a day while preg- nant, but two studies at Columbia University have suggested that as few as two drinks a week while pregnant may raise a woman’s risk of miscarriage. (One drink is 12 ounces of beer, five ounces of wine, or 1.25 ounces of distilled spirits.) Increased risk of breast cancer. In 2008, scientists at the National Cancer Institute released data from a seven-year survey of more than 100,000 postmenopausal women showing that even moderate drinking (one to two drinks a day) may increase by 32 percent a woman’s risk of developing estrogen-receptor positive (ER+) and progesterone-receptor positive (PR+) breast cancer, tumors whose growth is stimulated by hormones. No such link was found between consuming alcohol and the risk of developing ER-/PR- tumors (not fueled by hor- mones). The finding applies to all types of alcohol: beer, wine, and distilled spirits. Increased risk of oral cancer (cancer of the mouth and throat). Numerous studies confirm the A merican Cancer Societ y’s warn ing that men and women who consume more than t wo drinks a day are at higher risk of oral cancer than are nondrinkers or people who drink less. Increased risk of cancer of the colon and rectum. In the mid-1990s, studies at the University of Oklahoma suggested that men who drink more than five beers a day are at increased risk of rectal cancer. Later studies suggested that men and women who are heavy beer or spirits drinkers (but not those who are heavy wine drinkers) have a higher risk of colorectal cancers. Further studies are required to confirm these findings. Malnutrition. While moderate alcohol consumption stimulates appetite, alcohol abuses depresses it. In addition, an alcoholic may drink instead of eating. When an alcoholic does eat, excess alcohol in his/her body prevents absorption of nutrients and reduces the ability to synthesize new tissue. Hangover. Alcohol is absorbed from the stomach and small intestine and carried by the bloodstream to the liver, where it is oxidized to acetaldehyde by alcohol dehydrogenase (ADH), the enzyme our bodies use every day to metabolize the alcohol we produce when we digest carbohydrates. The acetaldehyde is converted to acetyl coenzyme A and either eliminated from the body or used in the synthesis of cholesterol, fatty acids, and body tis- sues. Although individuals vary widely in their capacity to metabolize alcohol, an adult of average size can metabolize the alcohol in four ounces (120 ml) whiskey in approximately five to six hours. If he or she drinks more than that, the amount of alcohol in the body will exceed the available supply of ADH. The surplus, unmetabolized alcohol will pile up in the bloodstream, interfering with the liver’s metabolic functions. Since alcohol decreases the reabsorption of water from the kidneys and may inhibit the secretion of an antidiuretic hormone, the drinker will begin to urinate copiously, losing magnesium, calcium, and zinc but retaining uric acid, which is irritating. The level of lactic acid in the body will increase, making him or her feel tired and out of sorts; the acid-base balance will be out of kilter; the blood vessels in the head will swell and throb; and the stomach, its lining irritated by the alcohol, will ache. The ultimate result is a hangover whose symptoms will disappear only when enough time has passed to allow the body to marshal the ADH needed to metabolize the extra alcohol in the person’s blood. Changes in body temperature. Alcohol dilates capillaries, tiny blood vessels just under the skin, producing a “flush” that temporarily warms the drinker. But drinking is not an effective way to stay warm in cold weather. Warm blood flowing up from the body core to the surface capillaries is quickly chilled, making you even colder when it circulates back into your organs. In addition, an alcohol flush triggers perspiration, further cooling your skin. Finally, very large amounts of alcohol may actually depress the mechanism that regulates body temperature. Impotence. Excessive drinking decreases libido (sexual desire) and interferes with the ability to achieve or sustain an erection. Migraine headache. Some alcoholic beverages contain chemicals that inhibit PST, an enzyme that breaks down certain alcohols in spirits so that they can be eliminated from the body. If they are not broken down by PST, these alcohols will build up in the bloodstream and may trigger a migraine headache. Gin and vodka appear to be the distilled spirits least likely to trigger headaches, brandy the most likely.
Food/Drug Interactions Acetaminophen (Tylenol, etc.). FDA recommends that people who regularly have three or more drinks a day consult a doctor before using acetaminophen. The alcohol/acetaminophen combination may cause liver failure. Anti-alcohol abuse drugs (disulfiram [Antabuse]). Taken concurrently with alcohol, the anti- alcoholism drug disulfiram can cause flushing, nausea, a drop in blood pressure, breathing difficulty, and confusion. The severity of the symptoms, which may var y among individu- als, generally depends on the amount of alcohol consumed and the amount of disulfiram in the body. Anticoagulants. Alcohol slows the body’s metabolism of anticoagulants (blood thinners), intensif ying the effect of the drugs and increasing the risk of side effects such as spontane- ous nosebleeds. Antidepressants. Alcohol may strengthen the sedative effects of antidepressants. Aspirin, ibuprofen, ketoprofen, naproxen and nonsteroidal anti-inflammatory drugs. Like alco- hol, these analgesics irritate the lining of the stomach and may cause gastric bleeding. Com- bining the two intensifies the effect. Insulin and oral hypoglycemics. Alcohol lowers blood sugar and interferes with the metabo- lism of oral antidiabetics; the combination may cause severe hypoglycemia. Sedatives and other central nervous system depressants (tranquilizers, sleeping pills, antide- pressants, sinus and cold remedies, analgesics, and medication for motion sickness). Alcohol intensifies the sedative effects of these medications and, depending on the dose, may cause drowsiness, sedation, respiratory depression, coma, or death. MAO inhibitors. Monoamine oxidase (M AO) inhibitors are drugs used as antidepressants or antihypertensives. They inhibit the action of natural enzymes that break down tyramine, a substance formed naturally when proteins are metabolized. Tyramine is a pressor amine, a chemical that constricts blood vessel and raises blood pressure. If you eat a food that contains tyramine while you are taking an M AO inhibitor, the pressor amine cannot be eliminated from your body and the result may be a hypertensive crisis (sustained elevated blood pressure). Brandy, a distilled spirit made from wine (which is fermented) contains tyramine. All other distilled spirits may be excluded from your diet when you are taking an M AO inhibitor because the spirits and the drug, which are both sedatives, may be hazard- ous in combination....

Symptoms Warning symptoms include dizziness, headache, oedema, vomiting, and the secretion of albumin (protein) in the urine. These are normally accompanied by a rise in blood pressure, which can be severe. Preeclamptic symptoms may be present for some days or weeks before the seizure takes place, and, if a woman is found to have these during antenatal care, preventive measures must be taken. Untreated, CONVULSIONS and unconsciousness are very likely, with serious migraine-like frontal headache and epigastric pain the symptoms.
Treatment Prevention of eclampsia by dealing with pre-eclamptic symptoms is the best management, but even this may not prevent convulsions. Hospital treatment is essential if eclampsia develops, preferably in a specialist unit. The treatment of the seizures is that generally applicable to convulsions of any kind, with appropriate sedatives given such as intravenous DIAZEPAM. HYDRALLAZINE intravenously should also be administered to reduce the blood pressure. Magnesium sulphate given intramuscularly sometimes helps to control the ?ts. The baby’s condition should be monitored throughout.
Urgent delivery of the baby, if necessary by CAESAREAN SECTION, is the most e?ective ‘treatment’ for a mother with acute eclampsia. (See PREGNANCY AND LABOUR.)
Women who have suffered from eclampsia are liable to suffer a recurrence in a further preganancy. Careful monitoring is required. There is a self-help organisation, Action on Pre-eclampsia (APEC), to advise on the condition.... Medicinal Plants Glossary
Ectopic pregnancy is more common in women who have had previous pelvic infections (see pelvic inflammatory disease) and with some types of IUD and progestogen-only oral contraceptives.
Most ectopic pregnancies are discovered in the first 2 months, often before the woman realizes she is pregnant. Symptoms usually include severe painin the lower abdomen and vaginal bleeding. Internal bleeding may cause symptoms of shock, such as pallor, sweating, and faintness.
Diagnosis is made by a transvaginal ultrasound examination and can be confirmed by ectopic laparoscopy. If the diagnosis is made early, medical treatment using the drug methotrexate may be considered. In most cases, surgery, usually minimally invasive surgery, to remove the pregnancy is carried out. If blood loss is severe, blood transfusions are needed. An affected fallopian tube is removed if it cannot be repaired.... BMA Medical Dictionary
Nutritional Profile Energy value (calories per serving): Moderate Protein: High Fat: Low to moderate Saturated fat: Low to moderate Cholesterol: Moderate Carbohydrates: Low Fiber: None Sodium: Low (fresh fish) High (some canned or salted fish) Major vitamin contribution: Vitamin A, vitamin D Major mineral contribution: Iodine, selenium, phosphorus, potassium, iron, calcium
About the Nutrients in This Food Like meat, poultry, milk, and eggs, fish are an excellent source of high- quality proteins with sufficient amount of all the essential amino acids. While some fish have as much or more fat per serving than some meats, the fat content of fish is always lower in saturated fat and higher in unsaturated fats. For example, 100 g/3.5 ounce cooked pink salmon (a fatty fish) has 4.4 g total fat, but only 0.7 g saturated fat, 1.2 g monounsaturated fat, and 1.7 g polyunsaturated fat; 100 g/3.5 ounce lean top sirloin has four grams fat but twice as much saturated fat (1.5 g), plus 1.6 g monounsatu- rated fat and only 0.2 g polyunsaturated fat. Omega-3 Fatty Acid Content of Various Fish (Continued) Fish Grams/ounce Rainbow trout 0.30 Lake whitefish 0.25 Source: “Food for t he Heart,” American Health, April 1985. Fish oils are one of the few natural food sources of vitamin D. Salmon also has vita- min A derived from carotenoid pigments in the plants eaten by the fish. The soft bones in some canned salmon and sardines are an excellent source of calcium. CAUTION: do not eat the bones in r aw or cook ed fish. the only bones consider ed edible ar e those in the canned products.

Diets That May Restrict or Exclude This Food Low-purine (antigout) diet Low-sodium diet (canned, salted, or smoked fish)
Buying This Food Look for: Fresh-smelling whole fish with shiny skin; reddish pink, moist gills; and clear, bulging eyes. The flesh should spring back when you press it lightly. Choose fish fillets that look moist, not dry. Choose tightly sealed, solidly frozen packages of frozen fish. In 1998, the FDA /National Center for Toxicological Research released for testing an inexpensive indicator called “Fresh Tag.” The indicator, to be packed with seafood, changes color if the product spoils. Avoid: Fresh whole fish whose eyes have sunk into the head (a clear sign of aging); fillets that look dry; and packages of frozen fish that are stained (whatever leaked on the package may have seeped through onto the fish) or are coated with ice crystals (the package may have defrosted and been refrozen).
Storing This Food Remove fish from plastic wrap as soon as you get it home. Plastic keeps out air, encouraging the growth of bacteria that make the fish smell bad. If the fish smells bad when you open the package, throw it out. Refrigerate all fresh and smoked fish immediately. Fish spoils quickly because it has a high proportion of polyunsaturated fatty acids (which pick up oxygen much more easily than saturated or monounsaturated fatty acids). Refrigeration also slows the action of microorgan- isms on the surface of the fish that convert proteins and other substances to mucopolysac- charides, leaving a slimy film on the fish. Keep fish frozen until you are ready to use it. Store canned fish in a cool cabinet or in a refrigerator (but not the freezer). The cooler the temperature, the longer the shelf life.
Preparing This Food Fresh fish. Rub the fish with lemon juice, then rinse it under cold running water. The lemon juice (an acid) will convert the nitrogen compounds that make fish smell “fishy” to compounds that break apart easily and can be rinsed off the fish with cool running water. R insing your hands in lemon juice and water will get rid of the fishy smell after you have been preparing fresh fish. Frozen fish. Defrost plain frozen fish in the refrigerator or under cold running water. Pre- pared frozen fish dishes should not be thawed before you cook them since defrosting will make the sauce or coating soggy. Salted dried fish. Salted dried fish should be soaked to remove the salt. How long you have to soak the fish depends on how much salt was added in processing. A reasonable average for salt cod, mackerel, haddock (finnan haddie), or herring is three to six hours, with two or three changes of water. When you are done, clean all utensils thoroughly with hot soap and hot water. Wash your cutting board, wood or plastic, with hot water, soap, and a bleach-and-water solution. For ultimate safety in preventing the transfer of microorganisms from the raw fish to other foods, keep one cutting board exclusively for raw fish, meats, and poultry, and a second one for everything else. Finally, don’t forget to wash your hands.
What Happens When You Cook This Food Heat changes the structure of proteins. It denatures the protein molecules so that they break apart into smaller fragments or change shape or clump together. These changes force moisture out of the tissues so that the fish turns opaque. The longer you cook fish, the more moisture it will lose. Cooked fish flakes because the connective tissue in fish “melts” at a relatively low temperature. Heating fish thoroughly destroys parasites and microorganisms that live in raw fish, making the fish safer to eat.
How Other Kinds of Processing Affect This Food Marinating. Like heat, acids coagulate the proteins in fish, squeezing out moisture. Fish marinated in citrus juices and other acids such as vinegar or wine has a firm texture and looks cooked, but the acid bath may not inactivate parasites in the fish. Canning. Fish is naturally low in sodium, but can ned fish often contains enough added salt to make it a high-sodium food. A 3.5-ounce ser ving of baked, fresh red salmon, for example, has 55 mg sodium, while an equal ser ving of regular can ned salmon has 443 mg. If the fish is can ned in oil it is also much higher in calories than fresh fish. Freezing. When fish is frozen, ice cr ystals form in the flesh and tear its cells so that mois- ture leaks out when the fish is defrosted. Commercial flash-freezing offers some protec- tion by freezing the fish so fast that the ice cr ystals stay small and do less damage, but all defrosted fish tastes drier and less palatable than fresh fish. Freezing slows but does not stop the oxidation of fats that causes fish to deteriorate. Curing. Fish can be cured (preser ved) by smoking, dr ying, salting, or pickling, all of which coagulate the muscle tissue and prevent microorganisms from growing. Each method has its own particular drawbacks. Smoking adds potentially carcinogenic chemicals. Dr ying reduces the water content, concentrates the solids and nutrients, increases the calories per ounce, and raises the amount of sodium.
Medical Uses and/or Benefits Protection against cardiovascular disease. The most important fats in fish are the poly- unsaturated acids k nown as omega-3s. These fatt y acids appear to work their way into heart cells where they seem to help stabilize the heart muscle and prevent potentially fatal arrhythmia (irregular heartbeat). A mong 85,000 women in the long-run n ing Nurses’ Health Study, those who ate fatt y fish at least five times a week were nearly 50 percent less likely to die from heart disease than those who ate fish less frequently. Similar results appeared in men in the equally long-run n ing Physicians’ Health Study. Some studies suggest that people may get similar benefits from omega-3 capsules. Researchers at the Consorzio Mario Negri Sud in Santa Maria Imbaro ( Italy) say that men given a one-gram fish oil capsule once a day have a risk of sudden death 42 percent lower than men given placebos ( “look-alike” pills with no fish oil). However, most nutrition scientists recom- mend food over supplements. Omega-3 Content of Various Food Fish Fish* (3 oz.)

Adverse Effects Associated with This Food Allergic reaction. According to the Merck Manual, fish is one of the 12 foods most likely to trigger classic food allergy symptoms: hives, swelling of the lips and eyes, and upset stom- ach. The others are berries (blackberries, blueberries, raspberries, strawberries), chocolate, corn, eggs, legumes (green peas, lima beans, peanuts, soybeans), milk, nuts, peaches, pork, shellfish, and wheat (see wheat cer ea ls). NOTE : Canned tuna products may contain sulfites in vegetable proteins used to enhance the tuna’s flavor. People sensitive to sulfites may suf- fer serious allergic reactions, including potentially fatal anaphylactic shock, if they eat tuna containing sulfites. In 1997, tuna manufacturers agreed to put warning labels on products with sulfites. Environmental contaminants. Some fish are contaminated with methylmercury, a compound produced by bacteria that chemically alters naturally occurring mercury (a metal found in rock and soil) or mercury released into water through industrial pollution. The methylmer- cury is absorbed by small fish, which are eaten by larger fish, which are then eaten by human beings. The larger the fish and the longer it lives the more methylmercury it absorbs. The measurement used to describe the amount of methylmercury in fish is ppm (parts per mil- lion). Newly-popular tilapia, a small fish, has an average 0.01 ppm, while shark, a big fish, may have up to 4.54 ppm, 450 times as much. That is a relatively small amount of methylmercur y; it will soon make its way harmlessly out of the body. But even small amounts may be hazardous during pregnancy because methylmercur y targets the developing fetal ner vous system. Repeated studies have shown that women who eat lots of high-mercur y fish while pregnant are more likely to deliver babies with developmental problems. As a result, the FDA and the Environ men- tal Protection Agency have now warned that women who may become pregnant, who are pregnant, or who are nursing should avoid shark, swordfish, king mackerel, and tilefish, the fish most likely to contain large amounts of methylmercur y. The same prohibition applies to ver y young children; although there are no studies of newborns and babies, the young brain continues to develop after birth and the logic is that the prohibition during pregnancy should extend into early life. That does not mean no fish at all should be eaten during pregnancy. In fact, a 2003 report in the Journal of Epidemiology and Community Health of data from an 11,585-woman study at the University of Bristol (England) shows that women who don’t eat any fish while pregnant are nearly 40 percent more likely to deliver low birth-weight infants than are women who eat about an ounce of fish a day, the equivalent of 1/3 of a small can of tuna. One theory is that omega-3 fatty acids in the fish may increase the flow of nutrient-rich blood through the placenta to the fetus. University of Southern California researchers say that omega-3s may also protect some children from asthma. Their study found that children born to asthmatic mothers who ate oily fish such as salmon at least once a month while pregnant were less likely to develop asthma before age five than children whose asthmatic pregnant mothers never ate oily fish. The following table lists the estimated levels of mercury in common food fish. For the complete list of mercury levels in fish, click onto www.cfsan.fda.gov/~frf/sea-mehg.html.

Like raw meat, raw fish may carry various pathogens, including fish tapeworm and flukes in freshwater fish and Salmonella or other microorganisms left on the fish by infected foodhandlers. Cooking the fish destroys these organisms. Scombroid poisoning. Bacterial decomposition that occurs after fish is caught produces a his- taminelike toxin in the flesh of mackerel, tuna, bonito, and albacore. This toxin may trigger a number of symptoms, including a flushed face immediately after you eat it. The other signs of scombroid poisoning—nausea, vomiting, stomach pain, and hives—show up a few minutes later. The symptoms usually last 24 hours or less.
Food/Drug Interactions Monoamine oxidase (MAO) inhibitors. Monoamine oxidase inhibitors are drugs used to treat depression. They inactivate naturally occurring enzymes in your body that metabolize tyramine, a substance found in many fermented or aged foods. Tyramine constricts blood vessels and increases blood pressure. If you eat a food such as pickled herring, which is high in tyramine, while you are taking an M AO inhibitor, your body may not be able to eliminate the tyramine and the result may be a hypertensive crisis....

It has been suggested that the o?cial recommendation of 200 micrograms a day in the diet should be doubled. (See APPENDIX 5: VITAMINS.)... Medical Dictionary
Lactation is initiated by a rise in the level of prolactin, a hormone produced by the pituitary gland. Galactorrhoea is caused by excessive secretion of prolactin due to a pituitary tumour or otherendocrine disease, such as hypothyroidism. Some antipsychotic drugs may also cause excessive secretion. Treatment with bromocriptine suppresses prolactin production, but the underlying cause may also need treatment. galactosaemia A rare, inherited condition in which the body is unable to convert the sugar galactose into glucose due to the absence of a liver enzyme. It causes no symptoms at birth, but jaundice, diarrhoea, and vomiting soon develop and the baby fails to gain weight. Untreated, the condition results in liver disease, cataract, and learning difficulties. The diagnosis is confirmed by urine and blood tests. The major source of galactose is the milk sugar lactose. Lactosefree milk must be used throughout life. gallbladder A small, pear-shaped sac situated under the liver that stores bile.

In mild cases of haemolytic disease, the newborn baby becomes slightly jaundiced during the first 24 hours of life (due to excess bilirubin in the blood) and slightly anaemic. In more severe cases, the level of bilirubin in the blood may increase to a dangerous level, causing a risk of kernicterus (a type of brain damage). Severely affected babies have marked anaemia while still in the uterus. They become swollen (hydrops fetalis) and are often stillborn.
In mild cases, no treatment is necessary. In other cases, the aim is to deliver the baby before the anaemia becomes severe, usually by induction of labour at 35–39 weeks’ gestation. If the baby is too young to be delivered safely, fetal blood transfusions may be necessary. After birth, phototherapy (light treatment that converts bilirubin in the skin into a water-soluble form that is more easily excreted from the body) can help to reduce jaundice. An exchange blood transfusion may be needed.... BMA Medical Dictionary
Hepatitis B (formerly known as serum hepatitis) is transmitted by infected blood or blood products contaminating hypodermic needles, blood transfusions, or tattooing needles, by unprotected sexual contact, or (rarely) by contact with any other body fluid. It often occurs in drug users. Symptoms, which develop suddenly after an incubation period of 1–6 months, include headache, fever, chills, general weakness, and jaundice. Treatment includes *interferon alfa and other oral antivirals (e.g. *lamivudine, *adefovir dipivoxil, entecavir). Most patients make a gradual recovery but the mortality rate is 5–20%. A vaccine is available.
Hepatitis C (formerly known as non-A, non-B hepatitis) has a mode of transmission similar to that of hepatitis B (predominantly intravenous drug abuse). Treatment is with interferon alfa, peginterferon alfa, ribavirin, telaprevir, and boceprevir.
Hepatitis D is a defective virus that can only proliferate when there is infection with hepatitis B. Patients with D virus usually have severe chronic hepatitis.
Hepatitis E is transmitted by infected food or drink and can cause acute hepatitis; it is especially severe in a pregnant patient.
Chronic hepatitis continues for months or years, eventually leading to *cirrhosis and possibly to malignancy (see hepatoma). It is usually caused by chronic viral hepatitis, alcohol, or autoimmune disease.... Oxford | Concise Colour Medical Dictionary

Genital herpes cannot be cured, but treatment can reduce the severity of symptoms. Antiviral drugs such as aciclovir make the ulcers less painful and also encourage healing. Other measures include taking analgesic drugs and bathing with a salt solution.
Once the virus enters the body, it stays there for the rest of the person’s life. Recurrent attacks may occur, usually during periods when the person is feeling run down, anxious, or depressed, before menstruation, or after sexual intercourse. The virus can be spread to others through sexual intercourse even when symptoms are absent. Recurrent attacks tend to become less frequent and less severe over time.Genital herpes may be passed from a pregnant woman to her baby during delivery.
If the virus can be detected in vaginal swabs, delivery by caesarean section is usually recommended.... BMA Medical Dictionary

Causes. Injury, tumour, blood clot, meningitis, or congenital malformation obstructing the aqueduct. Symptoms. Headache on the crown of the head, enlarged pupils, double vision, eyes squint and appear abnormally small, convulsions, slow onset of fever, high blood pressure, delirium, flushed cheeks, patient shuns the light.
Treatment. As a supportive aid to conventional treatment by hospital specialist or general medical practitioner.
Formula. Yarrow 2; Lily of the Valley 2; Ginkgo 1. Dose: Powders – 750mg (three 00 capsules or half a teaspoon). Liquid extracts – 1 teaspoon. Tinctures – 1-2 teaspoons every 2 hours for acute cases, otherwise thrice daily.
Ivy. Dr John Clarke, homoeopathic physician, reports the case of a colleague, Dr L. Cooper, who cured a case with one single dose of 1 drop mother-tincture of Ivy (Hedera helix). “Clear fluid (cerebrospinal rhinorrhoea) dripped from his nostrils for three weeks; 20-30 handkerchiefs being used a day.” Evidence of efficacy of the traditional reputation of 1-2 drops Ivy juice for the condition is lacking.

Treatment Crusts should be gently removed with SALINE. Mild cases respond to frequent application of mupiricin or NEOMYCIN/BACITRACIN ointment; more severe cases should be treated orally or, sometimes, intravenously with FLUCLOXACILLIN or one of the CEPHALOSPORINS. If the patient is allergic to penicillin, ERYTHROMYCIN can be used.
For severe, intractable cases, an oral retinoid drug called isotretinoin (commercially produced as Roaccutane®) can be used. It is given systemically but treatment must be supervised by a consultant dermatologist as serious side-effects, including possible psychiatric disturbance, can occur. The drug is also teratogenic (see TERATOGENESIS), so women who are, or who may become, pregnant must not take isotretinoin. It acts mainly by suppressing SEBUM production in the sebaceous glands and can be very e?ective. Recurrent bouts of impetigo should raise suspicion of underlying SCABIES or head lice. Bactericidal soaps and instilling an antibiotic into the nostrils may also help.... Medicinal Plants Glossary
The improvement in the infant mortality rate has occurred mainly in the period from the second month of life. There has been much less improvement in the neonatal mortality rate – that is, the number of infants dying during the ?rst four weeks of life, expressed as a proportion of every 1,000 live births. During the ?rst week of life the main causes of death are asphyxia, prematurity, birth injuries and congenital abnormalities. After the ?rst week the main cause of death is infection.
Social conditions also play an important role in infant mortality. In England and Wales the infant mortality rate in 1930–32 was: Social Class I (professional), 32·7; Social Class III (skilled workers), 57·6; Social Class V (unskilled workers), 77·1. Many factors come into play in producing these social variations, but overcrowding is undoubtedly one of the most important.
1838–9 146 1950–52 30 1851–60 154 1960–62 22 1900–02 142 1970–72 18 1910–12 110 1980–82 12 1920–22 82 1990–92 7 1930–32 67 1996 6·2 1940–42 59 1999 5.8 2000 5.6
It is thus evident that for a reduction of the infant mortality rate to the minimum ?gure, the following conditions must be met. Mothers and potential mothers must be housed adequately in healthy surroundings, particularly with regard to safe water supplies and sewage disposal. The pregnant and nursing mother must be ensured an adequate diet. E?ective antenatal supervision must be available to every mother, as well as skilled supervision during labour (see PREGNANCY AND LABOUR). The newborn infant must be adequately nursed and fed and mothers encouraged to breast feed. Environmental and public-health measures must be taken to ensure adequate housing, a clean milk supply and full availability of medical care including such protective measures as IMMUNISATION against diphtheria, measles, poliomyelitis and whooping-cough.

An IUD is inserted through the vagina and cervix into the uterine cavity. Once in position, an IUD provides immediate protection. Most IUDs have a plastic string attached to make removal easier and also to indicate its presence when in place. IUDs usually need to be replaced every 3–8 years.
Women who have been pregnant are less likely to have complications than women who have never been pregnant. For example, they may experience less pain on insertion and have lighter menstrual flow and lower expulsion rates. IUDs are usually not recommended for women with fibroids or an irregular uterine cavity. If menstrual flow is heavy, or there is a history or increased risk of pelvic inflammatory disease (PID), a progestogen IUD may be recommended.
Rarely, pregnancy can occur, although IUDs seldom cause problems and can be removed. Nonprogestogen IUDs increase the risk of PID, which can lead to permanent infertility. A rare complication of IUD use is perforation of the uterus, which most commonly occurs at the time of insertion.... BMA Medical Dictionary

A localised (focal) form of liver disease in all tropical/subtropical countries results from invasive Entamoeba histolytica infection (amoebic liver ‘abscess’); serology and imaging techniques assist in diagnosis. Hydatidosis also causes localised liver disease; one or more cysts usually involve the right lobe of the liver. Serological tests and imaging techniques are of value in diagnosis. Whilst surgery formerly constituted the sole method of management, prolonged courses of albendazole and/or praziquantel have now been shown to be e?ective; however, surgical intervention is still required in some cases.
Hepato-biliary disease is also a problem in many tropical/subtropical countries.

SYNONYMS: C. nobilis, C. madurensis, C. unshiu, C. deliciosa, European mandarin, true mandarin, tangerine, satsuma.
GENERAL DESCRIPTION: A small evergreen tree up to 6 metres high with glossy leaves, fragrant flowers and bearing fleshy fruit. The tangerine is larger than the mandarin and rounder, with a yellower skin, more like the original Chinese type.
DISTRIBUTION: Native to southern China and the Far East. Brought to Europe in 1805 and to America forty years later, where it was renamed the tangerine. The mandarin is produced mainly in Italy, Spain, Algeria, Cyprus, Greece, the Middle East and Brazil; the tangerine in Texas, Florida, California and Guinea.
OTHER SPECIES: There are many cultivars within this species: the terms tangerine (C. reticulata) and mandarin are used somewhat interchangeably, as is the word satsuma. They could be said to represent different chemotypes since the oils are quite different; see the Botanical Classification section.
HERBAL/FOLK TRADITION: The name comes from the fruit which was a traditional gift to the Mandarins of China. In France it is regarded as a safe children’s remedy for indigestion, hiccoughs, etc, and also for the elderly since it helps strengthen the digestive function and liver.
EXTRACTION: Essential oil by cold expression from the outer peel. A mandarin petitgrain oil is also produced in small quantities by steam distillation from the leaves and twigs.
CHARACTERISTICS: Mandarin oil is a yellowy-orange mobile liquid with a blue-violet hint, having an intensely sweet, almost floral citrus scent. It blends well with other citrus oils, especially neroli, and spice oils such as nutmeg, cinnamon and clove. Tangerine oil is an orange mobile liquid with a fresh, sweet, orangelike aroma. It has less body than mandarin and is little used in perfumery work.
PRINCIPAL CONSTITUENTS: Limonene, methyl methylanthranilate, geraniol, citral, citronella!, among others.
SAFETY DATA: Non-toxic, non-irritant, nonsensitizing. Possibly phototoxic, although it has not been demonstrated decisively.
AROMATHERAPY/HOME: USE
Skin care: Acne, congested and oily skin, scars, spots, stretch marks, toner.
Circulation muscles and joints: Fluid retention, obesity.
Digestive system: Digestive problems, dyspepsia, hiccoughs, intestinal problems.
Nervous system: Insomnia, nervous tension, restlessness. It is often used for children and pregnant women and is recommended in synergistic combinations with other citrus oils.
OTHER USES: Mandarin oil is used in soaps, cosmetics and perfumes, especially colognes. It is employed as a flavouring agent especially in sweets, soft drinks and liqueurs.... The Encyclopedia of Essential Oils
Ovulation (release of an egg from the follicle) usually occurs in the middle of the menstrual cycle.
The empty follicle also produces progesterone hormone, which makes the endometrium become swollen and thick with retained fluid.
This enables a fertilized egg to implant in the endometrium.
If pregnancy fails to occur, the production of oestrogens and progesterone diminishes.
The endometrium is then shed about 14 days after ovulation.
Uterine contractions force the menstrual discharge to be expelled into the vagina, accompanied by bleeding, which may last for 1–8 days.... BMA Medical Dictionary

Structural defects of the nipple are rare. An inverted nipple is usually a harmless abnormality of development. Nipple inversion that develops in older women is mostly due to ageing, but mammography may be advisable to rule out the possibility of cancer.
Cracked nipples, common in the last months of pregnancy and during breastfeeding, may lead to infective mastitis. Washing, drying, and moisturizing the nipple daily can help to prevent cracking. Papilloma of the nipple is a noncancerous swelling attached to the skin by a stalk. Paget’s disease of the nipple appears initially as persistent eczema of the nipple and is due to a slow-growing cancer arising in a milk duct. Surgical treatment is required.Discharge from the nipple occurs for various reasons.
A clear, straw-coloured discharge may develop in early pregnancy; a milky discharge may occur after breast-feeding is over.
Galactorrhoea (milk discharge in someone who is not pregnant or breast-feeding) may be caused by a hormone imbalance, or, rarely, a galactocele (a cyst under the areola).
A discharge containing pus indicates a breast abscess.
A bloodstained discharge may be due to a noncancerous breast disorder or cancer.... BMA Medical Dictionary
Occupational health includes both mental and physical health. It is about compliance with health-and-safety-at-work legislation (and common law duties) and about best practice in providing work environments that reduce risks to health and safety to lowest practicable levels. It includes workers’ ?tness to work, as well as the management of the work environment to accommodate people with disabilities, and procedures to facilitate the return to work of those absent with long-term illness. Occupational health incorporates several professional groups, including occupational physicians, occupational health nurses, occupational hygienists, ergonomists, disability managers, workplace counsellors, health-and-safety practitioners, and workplace physiotherapists.
In the UK, two key statutes provide a framework for occupational health: the Health and Safety at Work, etc. Act 1974 (HSW Act); and the Disability Discrimination Act 1995 (DDA). The HSW Act states that employers have a duty to protect the health, safety and welfare of their employees and to conduct their business in a way that does not expose others to risks to their health and safety. Employees and self-employed people also have duties under the Act. Modern health-and-safety legislation focuses on assessing and controlling risk rather than prescribing speci?c actions in di?erent industrial settings. Various regulations made under the HSW Act, such as the Control of Substances Hazardous to Health Regulations, the Manual Handling Operations Regulations and the Noise at Work Regulations, set out duties with regard to di?erent risks, but apply to all employers and follow the general principles of risk assessment and control. Risks should be controlled principally by removing or reducing the hazard at source (for example, by substituting chemicals with safer alternatives, replacing noisy machinery, or automating tasks to avoid heavy lifting). Personal protective equipment, such as gloves and ear defenders, should be seen as a last line of defence after other control measures have been put in place.
The employment provisions of the DDA require employers to avoid discriminatory practice towards disabled people and to make reasonable adjustments to working arrangements where a disabled person is placed at a substantial disadvantage to a non-disabled person. Although the DDA does not require employers to provide access to rehabilitation services – even for those injured or made ill at work – occupational-health practitioners may become involved in programmes to help people get back to work after injury or long-term illness, and many businesses see the retention of valuable sta? as an attractive alternative to medical retirement or dismissal on health grounds.
Although a major part of occupational-health practice is concerned with statutory compliance, the workplace is also an important venue for health promotion. Many working people rarely see their general practitioner and, even when they do, there is little time to discuss wider health issues. Occupational-health advisers can ?ll in this gap by providing, for example, workplace initiatives on stopping smoking, cardiovascular health, diet and self-examination for breast and testicular cancers. Such initiatives are encouraged because of the perceived bene?ts to sta?, to the employing organisation and to the wider public-health agenda. Occupational psychologists recognise the need for the working population to achieve a ‘work-life balance’ and the promotion of this is an increasing part of occupational health strategies.
The law requires employers to consult with their sta? on health-and-safety matters. However, there is also a growing understanding that successful occupational-health management involves workers directly in the identi?cation of risks and in developing solutions in the workplace. Trade unions play an active role in promoting occupational health through local and national campaigns and by training and advising elected workplace safety representatives.
Occupational medicine The branch of medicine that deals with the control, prevention, diagnosis, treatment and management of ill-health and injuries caused or made worse by work, and with ensuring that workers are ?t for the work they do.
Occupational medicine includes: statutory surveillance of workers’ exposure to hazardous agents; advice to employers and employees on eliminating or reducing risks to health and safety at work; diagnosis and treatment/management of occupational illness; advice on adapting the working environment to suit the worker, particularly those with disabilities or long-term health problems; and advice on the return to work and, if necessary, rehabilitation of workers absent through illness. Occupational physicians may play a wider role in monitoring the health of workplace populations and in advising employers on controlling health hazards where ill-health trends are observed. They may also conduct epidemiological research (see EPIDEMIOLOGY) on workplace diseases.
Because of the occupational physician’s dual role as adviser to both employer and employee, he or she is required to be particularly diligent with regards to the individual worker’s medical CONFIDENTIALITY. Occupational physicians need to recognise in any given situation the context they are working in, and to make sure that all parties are aware of this.
Occupational medicine is a medical discipline and thus is only part of the broader ?eld of occupational health. Although there are some speci?c clinical duties associated with occupational medicine, such as diagnosis of occupational disease and medical screening, occupational physicians are frequently part of a multidisciplinary team that might include, for example, occupational-health nurses, healthand-safety advisers, ergonomists, counsellors and hygienists. Occupational physicians are medical practitioners with a post-registration quali?cation in occupational medicine. They will have completed a period of supervised in-post training. In the UK, the Faculty of Occupational Medicine of the Royal College of Physicians has three categories of membership, depending on quali?cations and experience: associateship (AFOM); membership (MFOM); and fellowship (FFOM).
Occupational diseases Occupational diseases are illnesses that are caused or made worse by work. In their widest sense, they include physical and mental ill-health conditions.
In diagnosing an occupational disease, the clinician will need to examine not just the signs and symptoms of ill-health, but also the occupational history of the patient. This is important not only in discovering the cause, or causes, of the disease (work may be one of a number of factors), but also in making recommendations on how the work should be modi?ed to prevent a recurrence – or, if necessary, in deciding whether or not the worker is able to return to that type of work. The occupational history will help in deciding whether or not other workers are also at risk of developing the condition. It will include information on:
the nature of the work.
how the tasks are performed in practice.
the likelihood of exposure to hazardous agents (physical, chemical, biological and psychosocial).
what control measures are in place and the extent to which these are adhered to.
previous occupational and non-occupational exposures.
whether or not others have reported similar symptoms in relation to the work. Some conditions – certain skin conditions,
for example – may show a close relationship to work, with symptoms appearing directly only after exposure to particular agents or possibly disappearing at weekends or with time away from work. Others, however, may be chronic and can have serious long-term implications for a person’s future health and employment.
Statistical information on the prevalence of occupational disease in the UK comes from a variety of sources, including o?cial ?gures from the Industrial Injuries Scheme (see below) and statutory reporting of occupational disease (also below). Neither of these o?cial schemes provides a representative picture, because the former is restricted to certain prescribed conditions and occupations, and the latter suffers from gross under-reporting. More useful are data from the various schemes that make up the Occupational Diseases Intelligence Network (ODIN) and from the Labour Force Survey (LFS). ODIN data is generated by the systematic reporting of work-related conditions by clinicians and includes several schemes. Under one scheme, more than 80 per cent of all reported diseases by occupational-health physicians fall into just six of the 42 clinical disease categories: upper-limb disorders; anxiety, depression and stress disorders; contact DERMATITIS; lower-back problems; hearing loss (see DEAFNESS); and ASTHMA. Information from the LFS yields a similar pattern in terms of disease frequency. Its most recent survey found that over 2 million people believed that, in the previous 12 months, they had suffered from an illness caused or made worse by work and that
19.5 million working days were lost as a result. The ten most frequently reported disease categories were:
stress and mental ill-health (see MENTAL ILLNESS): 515,000 cases.
back injuries: 508,000.
upper-limb and neck disorders: 375,000.
lower respiratory disease: 202,000.
deafness, TINNITUS or other ear conditions: 170,000.
lower-limb musculoskeletal conditions: 100,000.
skin disease: 66,000.
headache or ‘eyestrain’: 50,000.
traumatic injury (includes wounds and fractures from violent attacks at work): 34,000.
vibration white ?nger (hand-arm vibration syndrome): 36,000. A person who develops a chronic occu
pational disease may be able to sue his or her employer for damages if it can be shown that the employer was negligent in failing to take reasonable care of its employees, or had failed to provide a system of work that would have prevented harmful exposure to a known health hazard. There have been numerous successful claims (either awarded in court, or settled out of court) for damages for back and other musculoskeletal injuries, hand-arm vibration syndrome, noise-induced deafness, asthma, dermatitis, MESOTHELIOMA and ASBESTOSIS. Employers’ liability (workers’ compensation) insurers are predicting that the biggest future rise in damages claims will be for stress-related illness. In a recent study, funded by the Health and Safety Executive, about 20 per cent of all workers – more than 5 million people in the UK – claimed to be ‘very’ or ‘extremely’ stressed at work – a statistic that is likely to have a major impact on the long-term health of the working population.
While victims of occupational disease have the right to sue their employers for damages, many countries also operate a system of no-fault compensation for the victims of prescribed occupational diseases. In the UK, more than 60 diseases are prescribed under the Industrial Injuries Scheme and a person will automatically be entitled to state compensation for disability connected to one of these conditions, provided that he or she works in one of the occupations for which they are prescribed. The following short list gives an indication of the types of diseases and occupations prescribed under the scheme:
CARPAL TUNNEL SYNDROME connected to the use of hand-held vibrating tools.
hearing loss from (amongst others) use of pneumatic percussive tools and chainsaws, working in the vicinity of textile manufacturing or woodworking machines, and work in ships’ engine rooms.
LEPTOSPIROSIS – infection with Leptospira (various listed occupations).
viral HEPATITIS from contact with human blood, blood products or other sources of viral hepatitis.
LEAD POISONING, from any occupation causing exposure to fumes, dust and vapour from lead or lead products.
asthma caused by exposure to, among other listed substances, isocyanates, curing agents, solder ?ux fumes and insects reared for research.
mesothelioma from exposure to asbestos.
In the UK, employers and the self-employed have a duty to report all occupational injuries (if the employee is o? work for three days or more as a result), diseases or dangerous incidents to the relevant enforcing authority (the Health and Safety Executive or local-authority environmental-health department) under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR). Despite this statutory duty, comparatively few diseases are reported so that ?gures generated from RIDDOR reports do not give a useful indication of the scale of occupational diseases in the UK. The statutory reporting of injuries is much better, presumably because of the clear and acute relationship between a workplace accident and the resultant injury. More than 160,000 injuries are reported under RIDDOR every year compared with just 2,500 or so occupational diseases, a gross underestimate of the true ?gure.
There are no precise ?gures for the number of people who die prematurely because of work-related ill-health, and it would be impossible to gauge the exact contribution that work has on, for example, cardiovascular disease and cancers where the causes are multifactorial. The toll would, however, dwarf the number of deaths caused by accidents at work. Around 250 people are killed by accidents at work in the UK each year – mesothelioma, from exposure to asbestos at work, alone kills more than 1,300 people annually.
The following is a sample list of occupational diseases, with brief descriptions of their aetiologies.
Inhaled materials
PNEUMOCONIOSIS covers a group of diseases which cause ?brotic lung disease following the inhalation of dust. Around 250–300 new cases receive bene?t each year – mostly due to coal dust with or without silica contamination. SILICOSIS is the more severe disease. The contraction in the size of the coal-mining industry as well as improved dust suppression in the mines have diminished the importance of this disease, whereas asbestos-related diseases now exceed 1,000 per year. Asbestos ?bres cause a restrictive lung disease but also are responsible for certain malignant conditions such as pleural and peritoneal mesothelioma and lung cancer. The lung-cancer risk is exacerbated by cigarette-smoking.
Even though the use of asbestos is virtually banned in the UK, many workers remain at risk of exposure because of the vast quantities present in buildings (much of which is not listed in building plans). Carpenters, electricians, plumbers, builders and demolition workers are all liable to exposure from work that disturbs existing asbestos. OCCUPATIONAL ASTHMA is of increasing importance – not only because of the recognition of new allergic agents (see ALLERGY), but also in the number of reported cases. The following eight substances are most frequently linked to occupational asthma (key occupations in brackets): isocyanates (spray painters, electrical processors); ?our and grain (bakers and farmers); wood dust (wood workers); glutaraldehyde (nurses, darkroom technicians); solder/colophony (welders, electronic assembly workers); laboratory animals (technicians, scientists); resins and glues (metal and electrical workers, construction, chemical processors); and latex (nurses, auxiliaries, laboratory technicians).
The disease develops after a short, symptomless period of exposure; symptoms are temporally related to work exposures and relieved by absences from work. Removal of the worker from exposure does not necessarily lead to complete cessation of symptoms. For many agents, there is no relationship with a previous history of ATOPY. Occupational asthma accounts for about 10 per cent of all asthma cases. DERMATITIS The risk of dermatitis caused by an allergic or irritant reaction to substances used or handled at work is present in a wide variety of jobs. About three-quarters of cases are irritant contact dermatitis due to such agents as acids, alkalis and solvents. Allergic contact dermatitis is a more speci?c response by susceptible individuals to a range of allergens (see ALLERGEN). The main occupational contact allergens include chromates, nickel, epoxy resins, rubber additives, germicidal agents, dyes, topical anaesthetics and antibiotics as well as certain plants and woods. Latex gloves are a particular cause of occupational dermatitis among health-care and laboratory sta? and have resulted in many workers being forced to leave their profession through ill-health. (See also SKIN, DISEASES OF.)
Musculoskeletal disorders Musculoskeletal injuries are by far the most common conditions related to work (see LFS ?gures, above) and the biggest cause of disability. Although not all work-related, musculoskeletal disorders account for 36.5 per cent of all disabilities among working-age people (compared with less than 4 per cent for sight and hearing impairment). Back pain (all causes – see BACKACHE) has been estimated to cause more than 50 million days lost every year in sickness absence and costs the UK economy up to £5 billion annually as a result of incapacity or disability. Back pain is a particular problem in the health-care sector because of the risk of injury from lifting and moving patients. While the emphasis should be on preventing injuries from occurring, it is now well established that the best way to manage most lower-back injuries is to encourage the patient to continue as normally as possible and to remain at work, or to return as soon as possible even if the patient has some residual back pain. Those who remain o? work on long-term sick leave are far less likely ever to return to work.
Aside from back injuries, there are a whole range of conditions affecting the upper limbs, neck and lower limbs. Some have clear aetiologies and clinical signs, while others are less well de?ned and have multiple causation. Some conditions, such as carpal tunnel syndrome, are prescribed diseases in certain occupations; however, they are not always caused by work (pregnant and older women are more likely to report carpal tunnel syndrome irrespective of work) and clinicians need to be careful when assigning work as the cause without ?rst considering the evidence. Other conditions may be revealed or made worse by work – such as OSTEOARTHRITIS in the hand. Much attention has focused on injuries caused by repeated movement, excessive force, and awkward postures and these include tenosynovitis (in?ammation of a tendon) and epicondylitis. The greatest controversy surrounds upper-limb disorders that do not present obvious tissue or nerve damage but nevertheless give signi?cant pain and discomfort to the individual. These are sometimes referred to as ‘repetitive strain injury’ or ‘di?use RSI’. The diagnosis of such conditions is controversial, making it di?cult for sufferers to pursue claims for compensation through the courts. Psychosocial factors, such as high demands of the job, lack of control and poor social support at work, have been implicated in the development of many upper-limb disorders, and in prevention and management it is important to deal with the psychological as well as the physical risk factors. Occupations known to be at particular risk of work-related upper-limb disorders include poultry processors, packers, electronic assembly workers, data processors, supermarket check-out operators and telephonists. These jobs often contain a number of the relevant exposures of dynamic load, static load, a full or excessive range of movements and awkward postures. (See UPPER LIMB DISORDERS.)
Physical agents A number of physical agents cause occupational ill-health of which the most important is occupational deafness. Workplace noise exposures in excess of 85 decibels for a working day are likely to cause damage to hearing which is initially restricted to the vital frequencies associated with speech – around 3–4 kHz. Protection from such noise is imperative as hearing aids do nothing to ameliorate the neural damage once it has occurred.
Hand-arm vibration syndrome is a disorder of the vascular and/or neural endings in the hands leading to episodic blanching (‘white ?nger’) and numbness which is exacerbated by low temperature. The condition, which is caused by vibrating tools such as chain saws and pneumatic hammers, is akin to RAYNAUD’S DISEASE and can be disabling.
Decompression sickness is caused by a rapid change in ambient pressure and is a disease associated with deep-sea divers, tunnel workers and high-?ying aviators. Apart from the direct effects of pressure change such as ruptured tympanic membrane or sinus pain, the more serious damage is indirectly due to nitrogen bubbles appearing in the blood and blocking small vessels. Central and peripheral nervous-system damage and bone necrosis are the most dangerous sequelae.
Radiation Non-ionising radiation from lasers or microwaves can cause severe localised heating leading to tissue damage of which cataracts (see under EYE, DISORDERS OF) are a particular variety. Ionising radiation from radioactive sources can cause similar acute tissue damage to the eyes as well as cell damage to rapidly dividing cells in the gut and bone marrow. Longer-term effects include genetic damage and various malignant disorders of which LEUKAEMIA and aplastic ANAEMIA are notable. Particular radioactive isotopes may destroy or induce malignant change in target organs, for example, 131I (thyroid), 90Sr (bone). Outdoor workers may also be at risk of sunburn and skin cancers. OTHER OCCUPATIONAL CANCERS Occupation is directly responsible for about 5 per cent of all cancers and contributes to a further 5 per cent. Apart from the cancers caused by asbestos and ionising radiation, a number of other occupational exposures can cause human cancer. The International Agency for Research on Cancer regularly reviews the evidence for carcinogenicity of compounds and industrial processes, and its published list of carcinogens is widely accepted as the current state of knowledge. More than 50 agents and processes are listed as class 1 carcinogens. Important occupational carcinogens include asbestos (mesothelioma, lung cancer); polynuclear aromatic hydrocarbons such as mineral oils, soots, tars (skin and lung cancer); the aromatic amines in dyestu?s (bladder cancer); certain hexavalent chromates, arsenic and nickel re?ning (lung cancer); wood and leather dust (nasal sinus cancer); benzene (leukaemia); and vinyl chloride monomer (angiosarcoma of the liver). It has been estimated that elimination of all known occupational carcinogens, if possible, would lead to an annual saving of 5,000 premature deaths in Britain.
Infections Two broad categories of job carry an occupational risk. These are workers in contact with animals (farmers, veterinary surgeons and slaughtermen) and those in contact with human sources of infection (health-care sta? and sewage workers).
Occupational infections include various zoonoses (pathogens transmissible from animals to humans), such as ANTHRAX, Borrelia burgdorferi (LYME DISEASE), bovine TUBERCULOSIS, BRUCELLOSIS, Chlamydia psittaci, leptospirosis, ORF virus, Q fever, RINGWORM and Streptococcus suis. Human pathogens that may be transmissible at work include tuberculosis, and blood-borne pathogens such as viral hepatitis (B and C) and HIV (see AIDS/HIV). Health-care workers at risk of exposure to infected blood and body ?uids should be immunised against hapatitis B.
Poisoning The incidence of occupational poisonings has diminished with the substitution of noxious chemicals with safer alternatives, and with the advent of improved containment. However, poisonings owing to accidents at work are still reported, sometimes with fatal consequences. Workers involved in the application of pesticides are particularly at risk if safe procedures are not followed or if equipment is faulty. Exposure to organophosphate pesticides, for example, can lead to breathing diffculties, vomiting, diarrhoea and abdominal cramps, and to other neurological effects including confusion and dizziness. Severe poisonings can lead to death. Exposure can be through ingestion, inhalation and dermal (skin) contact.
Stress and mental health Stress is an adverse reaction to excessive pressures or demands and, in occupational-health terms, is di?erent from the motivational impact often associated with challenging work (some refer to this as ‘positive stress’). Stress at work is often linked to increasing demands on workers, although coping can often prevent the development of stress. The causes of occupational stress are multivariate and encompass job characteristics (e.g. long or unsocial working hours, high work demands, imbalance between e?ort and reward, poorly managed organisational change, lack of control over work, poor social support at work, fear of redundancy and bullying), as well as individual factors (such as personality type, personal circumstances, coping strategies, and availability of psychosocial support outside work). Stress may in?uence behaviours such as smoking, alcohol consumption, sleep and diet, which may in turn affect people’s health. Stress may also have direct effects on the immune system (see IMMUNITY) and lead to a decline in health. Stress may also alter the course and response to treatment of conditions such as cardiovascular disease. As well as these general effects of stress, speci?c types of disorder may be observed.
Exposure to extremely traumatic incidents at work – such as dealing with a major accident involving multiple loss of life and serious injury
(e.g. paramedics at the scene of an explosion or rail crash) – may result in a chronic condition known as post-traumatic stress disorder (PTSD). PTSD is an abnormal psychological reaction to a traumatic event and is characterised by extreme psychological discomfort, such as anxiety or panic when reminded of the causative event; sufferers may be plagued with uncontrollable memories and can feel as if they are going through the trauma again. PTSD is a clinically de?ned condition in terms of its symptoms and causes and should not be used to include normal short-term reactions to trauma.... Medical Dictionary

Pregnancy lasts about 280 days and is calculated from the ?rst day of the last menstrual period – see MENSTRUATION. Pregnancy-testing kits rely on the presence of the hormone beta HUMAN CHORIONIC GONADOTROPHIN (b HCG) which is excreted in the woman’s urine as early as 30 days from the last menstrual period. The estimated date of delivery can be accurately estimated from the size of the developing fetus measured by ULTRASOUND (see also below) between seven and 24 weeks. ‘Term’ refers to the time that the baby is due; this can range from 38 weeks to 41 completed weeks.
Physical changes occur in early pregnancy – periods stop and the abdomen enlarges. The breasts swell, with the veins becoming prominent and the nipples darkening. About two in three women will have nausea with a few experiencing such severe vomiting as to require hospital admission for rehydration.
Antenatal care The aim of antenatal care is to ensure a safe outcome for both mother and child; it is provided by midwives (see MIDWIFE) and doctors. Formal antenatal care began in Edinburgh in the 1930s with the recognition that all aspects of pregnancy – normal and abnormal – warranted surveillance. Cooperation between general practitioners, midwives and obstetricians is now established, with pregnancies that are likely to progress normally being cared for in the community and only those needing special intervention being cared for in a hospital setting.
The initial visit (or booking) in the ?rst half of pregnancy will record the history of past events and the results of tests, with the aim of categorising the patients into normal or not. Screening tests including blood checks and ultrasound scans are a routine part of antenatal care. The ?rst ultrasound scan is done at about 11 weeks to date the pregnancy, with a further one done at 20 weeks – the anomaly scan – to assess the baby’s structure. Some obstetric units will check the growth of the baby with one further scan later in the pregnancy or, in the case of twin pregnancies (see below), many scans throughout. The routine blood tests include checks for ANAEMIA, DIABETES MELLITUS, sickle-cell disease and THALASSAEMIA, as well as for the blood group. Evidence of past infections is also looked for; tests for RUBELLA (German measles) and SYPHILIS are routine, whereas tests for human immunode?ciency virus (see AIDS/ HIV below) and HEPATITIS are being o?ered as optional, although there is compelling evidence that knowledge of the mother’s infection status is bene?cial to the baby.
Traditional antenatal care consists of regular appointments, initially every four weeks until 34 weeks, then fortnightly or weekly. At each visit the mother’s weight, urine and blood pressure are checked, and assessment of fetal growth and position is done by palpating the uterus. Around two-thirds of pregnancies and labours are normal: in the remainder, doctors and midwives need to increase the frequency of surveillance so as to prevent or deal with maternal and fetal problems.
Common complications of pregnancy
Some of the more common complications of pregnancy are listed below.
As well as early detection of medical complications, antenatal visits aim to be supportive and include emotional and educational care. Women with uncomplicated pregnancies are increasingly being managed by midwives and general practitioners in the community and only coming to the hospital doctors should they develop a problem. A small number will opt for a home delivery, but facilities for providing such a service are not always available in the UK.
Women requiring more intensive surveillance have their management targeted to the speci?c problems encountered. Cardiologists will see mothers-to-be with heart conditions, and those at risk of diabetes are cared for in designated clinics with specialist sta?. Those women needing more frequent surveillance than standard antenatal care can be looked after in maternity day centres. These typically include women with mildly raised blood pressure or those with small babies. Fetal medicine units have specialists who are highly skilled in ultrasound scanning and specialise in the diagnosis and management of abnormal babies still in the uterus. ECTOPIC PREGNANCY Chronic abdominal discomfort early in pregnancy may be caused by unruptured ectopic pregnancy, when, rarely, the fertilised OVUM starts developing in the Fallopian tube (see FALLOPIAN TUBES) instead of the uterus. The patient needs hospital treatment and LAPAROSCOPY. A ruptured ectopic pregnancy causes acute abdominal symptoms and collapse, and the woman will require urgent abdominal surgery. URINARY TRACT INFECTIONS These affect around 2 per cent of pregnant women and are detected by a laboratory test of a mid-stream specimen of urine. In pregnancy, symptoms of these infections do not necessarily resemble those experienced by non-pregnant women. As they can cause uterine irritability and possible premature labour (see below), it is important to ?nd and treat them appropriately. ANAEMIA is more prevalent in patients who are vegetarian or on a poor diet. Iron supplements are usually given to women who have low concentrations of HAEMOGLOBIN in their blood (less than 10.5 g/dl) or who are at risk of becoming low in iron, from bleeding, twin pregnancies and those with placenta previa (see below). ANTEPARTUM HAEMORRHAGE Early in pregnancy, vaginal bleedings may be due to a spontaneous or an incomplete therapeutic ABORTION. Bleeding from the genital tract between 24 completed weeks of pregnancy and the start of labour is called antepartum haemorrhage. The most common site is where the PLACENTA is attached to the wall of the uterus. If the placenta separates before delivery, bleeding occurs in the exposed ‘bed’. When the placenta is positioned in the upper part of the uterus it is called an abruption. PLACENTA PRAEVIA is sited in the lower part and blocks or partly blocks the cervix (neck of the womb); it can be identi?ed at about the 34th week. Ten per cent of episodes of antepartum bleeding are caused by placenta previa, and it may be associated with bleeding at delivery. This potentially serious complication is diagnosed by ultrasound scanning and may require a caesarean section (see below) at delivery. INCREASED BLOOD PRESSURE, associated with protein in the urine and swelling of the limbs, is part of a condition known as PRE-ECLAMPSIA. This occurs in the second half of pregnancy in about 1 in 10 women expecting their ?rst baby, and is mostly very mild and of no consequence to the pregnancy. However, some women can develop extremely high blood pressures which can adversely affect the fetus and cause epileptic-type seizures and bleeding disorders in the mother. This serious condition is called ECLAMPSIA. For this reason a pregnant woman with raised blood pressure or PROTEIN in her urine is carefully evaluated with blood tests, often in the maternity day assessment unit. The condition can be stopped by delivery of the baby, and this will be done if the mother’s or the fetus’s life is in danger. If the condition is milder, and the baby not mature enough for a safe delivery, then drugs can be used to control the blood pressure. MISCARRIAGE Also called spontaneous abortion, miscarriage is the loss of the fetus. There are several types:
threatened miscarriage is one in which some vaginal bleeding occurs, the uterus is enlarged, but the cervix remains closed and pregnancy usually proceeds.
inevitable miscarriage usually occurs before the 16th week and is typi?ed by extensive blood loss through an opened cervix and cramp-like abdominal pain; some products of conception are lost but the developing placental area (decidua) is retained and an operation may be necessary to clear the womb.
missed miscarriages, in which the embryo dies and is absorbed, but the decidua (placental area of uterine wall) remains and may cause abdominal discomfort and discharge of old blood.
THERAPEUTIC ABORTION is performed on more than 170,000 women annually in England and Wales. Sometimes the woman may not have arranged the procedure through the usual health-care channels, so that a doctor may see a patient with vaginal bleeding, abdominal discomfort or pain, and open cervix – symptoms which suggest that the decidua and a blood clot have been retained; these retained products will need to be removed by curettage.
Septic abortions are now much less common in Britain than before the Abortion Act (1967) permitted abortion in speci?ed circumstances. The cause is the passage of infective organisms from the vagina into the uterus, with Escherichia coli and Streptococcus faecalis the most common pathogenic agents. The woman has abdominal pain, heavy bleeding, usually fever and sometimes she is in shock. The cause is usually an incomplete abortion or one induced in unsterile circumstances. Antibiotics and curettage are the treatment. INTRAUTERINE GROWTH RETARDATION describes a slowing of the baby’s growth. This can be diagnosed by ultrasound scanning, although there is a considerable margin of error in estimates of fetal weight. Trends in growth are favoured over one-o? scan results alone. GESTATIONAL DIABETES is a condition that is more common in women who are overweight or have a family member with diabetes. If high concentrations of blood sugar are found, e?orts are made to correct it as the babies can become very fat (macrosomia), making delivery more di?cult. A low-sugar diet is usually enough to control the blood concentration of sugars; however some women need small doses of INSULIN to achieve control. FETAL ABNORMALITIES can be detected before birth using ultrasound. Some of these defects are obvious, such as the absence of kidneys, a condition incompatible with life outside the womb. These women can be o?ered a termination of their pregnancy. However, more commonly, the pattern of problems can only hint at an abnormality and closer examination is needed, particularly in the diagnosis of chromosomal deformities such as DOWN’S (DOWN) SYNDROME (trisomy 21 or presence of three 21 chromosomes instead of two).
Chromosomal abnormalities can be de?nitively diagnosed only by cell sampling such as amniocentesis (obtaining amniotic ?uid – see AMNION – from around the baby) done at 15 weeks onwards, and chorionic villus sampling (sampling a small part of the placenta) – another technique which can be done from 12 weeks onwards. Both have a small risk of miscarriage associated with them; consequently, they are con?ned to women at higher risk of having an abnormal fetus.
Biochemical markers present in the pregnant woman’s blood at di?erent stages of pregnancy may have undergone changes in those carrying an abnormal fetus. The ?rst such marker to be routinely used was a high concentration of alpha-fetol protein in babies with SPINA BIFIDA (defects in the covering of the spinal cord). Fuller research has identi?ed a range of diagnostic markers which are useful, and, in conjunction with other factors such as age, ethnic group and ultrasound ?ndings, can provide a predictive guide to the obstetrician – in consultation with the woman – as to whether or not to proceed to an invasive test. These tests include pregnancy-associated plasma protein assessed from a blood sample taken at 12 weeks and four blood tests at 15–22 weeks – alphafetol protein, beta human chorionic gonadotrophin, unconjugated oestriol and inhibin A. Ultrasound itself can reveal physical ?ndings in the fetus, which can be more common in certain abnormalities. Swelling in the neck region of an embryo in early pregnancy (increased nuchal thickness) has good predictive value on its own, although its accuracy is improved in combination with the biochemical markers. The e?ectiveness of prenatal diagnosis is rapidly evolving, the aim being to make the diagnosis as early in the pregnancy as possible to help the parents make more informed choices. MULTIPLE PREGNANCIES In the UK, one in 95 deliveries is of twins, while the prevalence of triplets is one in 10,000 and quadruplets around one in 500,000. Racial variations occur, with African women having a prevalence rate of one in 30 deliveries for twins and Japanese women a much lower rate than the UK ?gure. Multiple pregnancies occur more often in older women, and in the UK the prevalence of fertility treatments, many of these being given to older women, has raised the incidence. There is now an o?cial limit of three eggs being transferred to a woman undergoing ASSISTED CONCEPTION (gamete intrafallopian transfer, or GIFT).
Multiple pregnancies are now usually diagnosed as a result of routine ultrasound scans between 16 and 20 weeks of pregnancy. The increased size of the uterus results in the mother having more or worse pregnancy-related conditions such as nausea, abdominal discomfort, backache and varicose veins. Some congenital abnormalities in the fetus occur more frequently in twins: NEURAL TUBE defects, abnormalities of the heart and the incidence of TURNER’S SYNDROME and KLINEFELTER’S SYNDROME are examples. Such abnormalities may be detected by ultrasound scans or amniocentesis. High maternal blood pressure and anaemia are commoner in women with multiple pregnancies (see above).
The growth rates of multiple fetuses vary, but the di?erence between them and single fetuses are not that great until the later stages of pregnancy. Preterm labour is commoner in multiple pregnancies: the median length of pregnancy is 40 weeks for singletons, 37 for twins and 33 for triplets. Low birth-weights are usually the result of early delivery rather than abnormalities in growth rates. Women with multiple pregnancies require more frequent and vigilant antenatal assessments, with their carers being alert to the signs of preterm labour occurring. CEPHALOPELVIC DISPROPORTION Disparity between the size of the fetus and the mother’s pelvis is not common in the UK but is a signi?cant problem in the developing world. Disparity is classi?ed as absolute, when there is no possibility of delivery, and relative, when the baby is large but delivery (usually after a dif?cult labour) is possible. Causes of absolute disparity include: a large baby – heavier than 5 kg at birth; fetal HYDROCEPHALUS; and an abnormal maternal pelvis. The latter may be congenital, the result of trauma or a contraction in pelvic size because of OSTEOMALACIA early in life. Disproportion should be suspected if in late pregnancy the fetal head has not ‘engaged’ in the pelvis. Sometimes a closely supervised ‘trial of labour’ may result in a successful, if prolonged, delivery. Otherwise a caesarean section (see below) is necessary. UNUSUAL POSITIONS AND PRESENTATIONS OF THE BABY In most pregnant women the baby ?ts into the maternal pelvis head-?rst in what is called the occipito-anterior position, with the baby’s face pointing towards the back of the pelvis. Sometimes, however, the head may face the other way, or enter the pelvis transversely – or, rarely, the baby’s neck is ?exed backwards with the brow or face presenting to the neck of the womb. Some malpositions will correct naturally; others can be manipulated abdominally during pregnancy to a better position. If, however, the mother starts labour with the baby’s head badly positioned or with the buttocks instead of the head presenting (breech position), the labour will usually be longer and more di?cult and may require intervention using special obstetric forceps to assist in extracting the baby. If progress is poor and the fetus distressed, caesarean section may be necessary. HIV INFECTION Pregnant women who are HIV positive (see HIV; AIDS/HIV) should be taking antiviral drugs in the ?nal four to ?ve months of pregnancy, so as to reduce the risk of infecting the baby in utero and during birth by around 50 per cent. Additional antiviral treatment is given before delivery; the infection risk to the baby can be further reduced – by about 40 per cent – if delivery is by caesarean section. The mother may prefer to have the baby normally, in which case great care should be taken not to damage the baby’s skin during delivery. The infection risk to the baby is even further reduced if it is not breast fed. If all preventive precautions are taken, the overall risk of the infant becoming infected is cut to under 5 per cent.
Premature birth This is a birth that takes place before the end of the normal period of gestation, usually before 37 weeks. In practice, however, it is de?ned as a birth that takes place when the baby weighs less than 2·5 kilograms (5••• pounds). Between 5 and 10 per cent of babies are born prematurely, and in around 40 per cent of premature births the cause is unknown. Pre-eclampsia is the most common known cause; others include hypertension, chronic kidney disease, heart disease and diabetes mellitus. Multiple pregnancy is another cause. In the vast majority of cases the aim of management is to prolong the pregnancy and so improve the outlook for the unborn child. This consists essentially of rest in bed and sedation, but there are now several drugs, such as RITODRINE, that may be used to suppress the activity of the uterus and so help to delay premature labour. Prematurity was once a prime cause of infant mortality but modern medical care has greatly improved survival rates in developing countries.
Labour Also known by the traditional terms parturition, childbirth or delivery, this is the process by which the baby and subsequently the placenta are expelled from the mother’s body. The onset of labour is often preceded by a ‘show’ – the loss of the mucus and blood plug from the cervix, or neck of the womb; this passes down the vagina to the exterior. The time before the beginning of labour is called the ‘latent phase’ and characteristically lasts 24 hours or more in a ?rst pregnancy. Labour itself is de?ned by regular, painful contractions which cause dilation of the neck of the womb and descent of the fetal head. ‘Breaking of the waters’ is the loss of amniotic ?uid vaginally and can occur any time in the delivery process.
Labour itself is divided into three stages: the ?rst is from the onset of labour to full (10 cm) dilation of the neck of the womb. This stage varies in length, ideally taking no more than one hour per centimetre of dilation. Progress is monitored by regular vaginal examinations, usually every four hours. Fetal well-being is observed by intermittent or continuous monitoring of the fetal heart rate in relation to the timing and frequency of the contractions. The print-out is called a cardiotocograph. Abnormalities of the fetal heart rate may suggest fetal distress and may warrant intervention. In women having their ?rst baby (primigravidae), the common cause of a slow labour is uncoordinated contractions which can be overcome by giving either of the drugs PROSTAGLANDIN or OXYTOCIN, which provoke contractions of the uterine muscle, by an intravenous drip. Labours which progress slowly or not at all may be due to abnormal positioning of the fetus or too large a fetus, when prostaglandin or oxytocin is used much more cautiously.
The second stage of labour is from full cervical dilation to the delivery of the baby. At this stage the mother often experiences an irresistible urge to push the baby out, and a combination of strong coordinated uterine contractions and maternal e?ort gradually moves the baby down the birth canal. This stage usually lasts under an hour but can take longer. Delay, exhaustion of the mother or distress of the fetus may necessitate intervention by the midwife or doctor. This may mean enlarging the vaginal opening with an EPISIOTOMY (cutting of the perineal outlet – see below) or assisting the delivery with specially designed obstetric forceps or a vacuum extractor (ventouse). If the cervix is not completely dilated or open and the head not descended, then an emergency caesarean section may need to be done to deliver the baby. This procedure involves delivering the baby and placenta through an incision in the mother’s abdomen. It is sometimes necessary to deliver by planned or elective caesarean section: for example, if the placenta is low in the uterus – called placenta praevia – making a vaginal delivery dangerous.
The third stage occurs when the placenta (or afterbirth) is delivered, which is usually about 10–20 minutes after the baby. An injection of ergometrine and oxytocin is often given to women to prevent bleeding.
Pain relief in labour varies according to the mother’s needs. For uncomplicated labours, massage, reassurance by a birth attendant, and a warm bath and mobilisation may be enough for some women. However, some labours are painful, particularly if the woman is tired or anxious or is having her ?rst baby. In these cases other forms of analgesia are available, ranging from inhalation of NITROUS OXIDE GAS, injection of PETHIDINE HYDROCHLORIDE or similar narcotic, and regional local anaesthetic (see ANAESTHESIA).
Once a woman has delivered, care continues to ensure her and the baby’s safety. The midwives are involved in checking that the uterus returns to its normal size and that there is no infection or heavy bleeding, as well as caring for stitches if needed. The normal blood loss after birth is called lochia and generally is light, lasting up to six weeks. Midwives o?er support with breast feeding and care of the infant and will visit the parents at home routinely for up to two weeks.
Some complications of labour All operative deliveries in the UK are now done in hospitals, and are performed if a spontaneous birth is expected to pose a bigger risk to the mother or her child than a specialist-assisted one. Operative deliveries include caesarean section, forceps-assisted deliveries and those in which vacuum extraction (ventouse) is used. CAESAREAN SECTION Absolute indications for this procedure, which is used to deliver over 15 per cent of babies in Britain, are cephalopelvic disproportion and extensive placenta praevia, both discussed above. Otherwise the decision to undertake caesarean section depends on the clinical judgement of the specialist and the views of the mother. The rise in the proportion of this type of intervention (from 5 per cent in the 1930s to its present level of over 23 per cent
P
of the 600,000 or so annual deliveries in England) has been put down to defensive medicine
– namely, the doctor’s fear of litigation (initiated often because the parents believe that the baby’s health has suffered because the mother had an avoidably di?cult ‘natural’ labour). In Britain, over 60 per cent of women who have had a caesarean section try a vaginal delivery in a succeeding pregnancy, with about two-thirds of these being successful. Indications for the operation include:
absolute and relative cephalopelvic disproportion.
placenta previa.
fetal distress.
prolapsed umbilical cord – this endangers the viability of the fetus because the vital supply of oxygen and nutrients is interrupted.
malpresentation of the fetus such as breech or transverse lie in the womb.
unsatisfactory previous pregnancies or deliveries.
a request from the mother.
Caesarean sections are usually performed using regional block anaesthesia induced by a spinal or epidural injection. This results in loss of feeling in the lower part of the body; the mother is conscious and the baby not exposed to potential risks from volatile anaesthetic gases inhaled by the mother during general anaesthesia. Post-operative complications are higher with general anaesthesia, but maternal anxiety and the likelihood that the operation might be complicated and di?cult are indications for using it. A general anaesthetic may also be required for an acute obstetric emergency. At operation the mother’s lower abdomen is opened and then her uterus opened slowly with a transverse incision and the baby carefully extracted. A transverse incision is used in preference to the traditional vertical one as it enables the woman to have a vaginal delivery in any future pregnancy with a much smaller risk of uterine rupture. Women are usually allowed to get up within 24 hours and are discharged after four or ?ve days. FORCEPS AND VENTOUSE DELIVERIES Obstetric forceps are made in several forms, but all are basically a pair of curved blades shaped so that they can obtain a purchase on the baby’s head, thus enabling the operator to apply traction and (usually) speed up delivery. (Sometimes they are used to slow down progress of the head.) A ventouse or vacuum extractor comprises an egg-cup-shaped metal or plastic head, ranging from 40 to 60 mm in diameter with a hollow tube attached through which air is extracted by a foot-operated vacuum pump. The instrument is placed on the descending head, creating a negative pressure on the skin of the scalp and enabling the operator to pull the head down. In mainland Europe, vacuum extraction is generally preferred to forceps for assisting natural deliveries, being used in around 5 per cent of all deliveries. Forceps have a greater risk of causing damage to the baby’s scalp and brain than vacuum extraction, although properly used, both types should not cause any serious damage to the baby.
Episiotomy Normal and assisted deliveries put the tissues of the genital tract under strain. The PERINEUM is less elastic than the vagina and, if it seems to be splitting as the baby’s head
moves down the birth canal, it may be necessary to cut the perineal tissue – a procedure called an episiotomy – to limit damage. This is a simple operation done under local anaesthetic. It should be done only if there is a speci?c indication; these include:
to hasten the second stage of labour if the fetus is distressed.
to facilitate the use of forceps or vacuum extractor.
to enlarge a perineum that is restricted because of unyielding tissue, perhaps because of a scar from a previous labour. Midwives as well as obstetricians are trained
to undertake and repair (with sutures) episiotomies.

The haemagglutination inhibition test This, and the subsequent tests to be mentioned, are known as immunological tests. They are based upon the e?ect of the urine from a pregnant woman upon the interaction of red blood cells, which have been sensitised to human gonadotrophin, and anti-gonadotrophin serum. They have the great practical advantage of being performed in a test-tube or even on a slide. Because of their ease and speed of performance, a result can be obtained in two hours.
Enzyme-linked immunosorbent assay (ELISA) This is the basis of many of the pregnancy-testing kits obtainable from pharmacies. It is a highly sensitive antibody test and can detect very low concentrations of human chorionic gonadotrophin. Positive results show up as early as ten days after fertilisation – namely, four days before the ?rst missed period.
Ultrasound The fetal sac can be detected by ULTRASOUND from ?ve weeks, and a fetal echo at around six or seven weeks (see also PRENATAL SCREENING OR DIAGNOSIS).... Medical Dictionary
Problems may also be caused in a developing baby if a pregnant woman drinks alcohol, smokes (see tobaccosmoking), or takes drugs of abuse. The babies of women who use heroin during pregnancy tend to have a low birthweight and a higher death rate than normal during the first few weeks of life. Babies of women who abuse drugs intravenously are at high risk of HIV infection.... BMA Medical Dictionary

ULTRASOUND scanning is probably the most widely used diagnostic tool in obstetric practice. It can detect structural abnormalities such as SPINA BIFIDA and CLEFT PALATE and even cardiac and renal problems. A series of scans can assess whether the baby is growing at a normal rate; ultrasound may also be used to assist with other diagnostic tests (e.g. AMNIOCENTESIS – see below).
Tests on the mother’s blood can also diagnose fetal abnormalities. Alphafetoprotein (AFP) is produced by babies and ‘leaks’ into the AMNIOTIC FLUID and is absorbed by the mother. In spina bi?da and other neural-tube defects there is increased leakage of AFP, and a blood test at 16 weeks’ gestation can detect a raised level which suggests the presence of these abnormalities.
The triple test, also performed at 16 weeks, measures AFP and two hormones – HUMAN CHORIONIC GONADOTROPHIN and unconjugated OESTRADIOL – and is used in diagnosing DOWN’S (DOWN) SYNDROME.
Amniocentesis involves inserting a needle through the mother’s abdominal wall into the uterus to remove a sample of amniotic ?uid at 16–18 weeks. Examination of the ?uid and the cells it contains is used in the diagnosis of Down’s syndrome and other inherited disorders. The test carries a small risk of miscarriage.
Chorionic villus sampling may be used to diagnose various inherited conditions. A small amount of tissue from the developing PLACENTA is removed for analysis: this test has the advantages of having a lower incidence of miscarriage than amniocentesis and is carried out at an earlier stage (9–13 weeks).
Analysis of a blood sample removed from the umbilical cord (cordocentesis) may diagnose infections in the uterus, blood disorders or inherited conditions.
Direct observation of the fetus via a viewing instrument called a fetoscope is also used diagnostically and will detect structural abnormalities.
Most tests have a recognised incidence of false positive and negative results and are therefore usually cross-checked with another test. Counselling of the parents about prenatal tests is important. This allows them to make an informed choice which may not necessarily involve terminating the pregnancy if an abnormality is found. (See PREGNANCY AND LABOUR.)... Medical Dictionary

Chronic pyelonephritis may start in childhood, and the usual cause is back ?ow of urine from the bladder into one of the ureters – perhaps because of a congenital deformity of the valve where the ureter drains into the bladder. Constant urine re?ux results in recurrent infection of the kidney and damage to its tissue. Full investigation of the urinary tract is essential and, if an abnormality is detected, surgery may well be required to remedy it. HYPERTENSION and renal failure may be serious complications of pyelonephritis (see also KIDNEYS, DISEASES OF).... Medical Dictionary

The Rh system is based on the presence or absence in the blood of several factors, the most important of which is a substance called D antigen. Rh-positive blood contains D antigen, whereas Rhnegative blood does not. The blood type is determined by genes.Rhesus incompatibility results if a Rhnegative woman is exposed to the blood of her Rh-positive baby while it is being born. There are usually no problems during the first pregnancy with a Rh-positive baby. However, the woman may produce antibodies against the D antigen; in a subsequent pregnancy with a Rh-positive baby, these antibodies may cross the placenta and attack the red blood cells of the fetus. A Rhnegative woman can also be sensitized if she has had a miscarriage, abortion, or amniocentesis, in which the fetus’s Rhpositive blood enters her circulation.
Rhesus incompatibility is now uncommon because injections of anti-D(Rh0) immunoglobulin are given routinely to Rh-negative women during pregnancy and at delivery. They are also given after miscarriage, abortion, amniocentesis, or any procedure that might result in exposure of the mother to fetal blood cells.... BMA Medical Dictionary
Cause A virus spread by close contact with infected individuals. Rubella is infectious for a week before the rash appears and at least four days afterwards. It occurs in epidemics (see EPIDEMIC) every three years or so, predominantly in the winter and spring. Children are more likely to be affected than infants. One attack gives permanent IMMUNITY. The incubation period is usually 14–21 days.
Symptoms are very mild, and the disease is not at all serious. On the day of onset there may be shivering, headache, slight CATARRH with sneezing, coughing and sore throat, with very slight fever – not above 37·8 °C (100 °F). At the same time the glands of the neck become enlarged. Within 24 hours of the onset a pink, slightly raised eruption appears, ?rst on the face or neck, then on the chest, and the second day spreads all over the body. The clinical signs and symptoms of many other viral infections are indistinguishable from rubella so a precise diagnosis cannot be made without taking samples (such as saliva) for antibody testing, but this is rarely done in practice.
An attack of German measles during the early months of pregnancy may be responsible for CONGENITAL defects in the FETUS (for information on fetal abnormalities, see under PREGNANCY AND LABOUR). The incidence of such defects is not precisely known, but probably around 20 per cent of children whose mothers have had German measles in the ?rst three months of the pregnancy are born with congenital defects. These defects take a variety of forms, but the most important ones are: low birth weight with retarded physical development; malformations of the HEART; cataract (see under EYE, DISORDERS OF); and DEAFNESS.
Treatment There is no speci?c treatment. Children who develop the disease should not return to school until they have recovered, and in any case not before four days have passed from the onset of the rash.
In view of the possible dangerous e?ect of the disease upon the fetus, particular care should be taken to isolate pregnant mothers from contact with infected subjects. As the risk is particularly high during the ?rst 16 weeks of pregnancy, any pregnant mother exposed to infection during this period should be given an intramuscular injection of GAMMA-GLOBULIN. A vaccine is available to protect an individual against rubella (see IMMUNISATION).
In the United Kingdom it is NHS policy for all children to have the combined measles, mumps and rubella vaccine (see MMR VACCINE), subject to parental consent. All women of childbearing age, who have been shown by a simple laboratory test not to have had the disease, should be vaccinated, provided that the woman is not pregnant at the time and has not been exposed to the risk of pregnancy during the previous eight weeks.... Medical Dictionary
The rubella virus is spread by motherto-baby transmission and in airborne droplets; it has an incubation period of 2–3 weeks. Infection usually occurs in children aged 6–12. A rash appears on the face, spreads to the trunk and limbs, then disappears after a few days. There may be slight fever and enlarged lymph nodes at the back of the neck.
The virus may be transmitted from a few days before symptoms appear until one day after they disappear. An unborn baby is at risk if the mother is infected during the first 4 months of pregnancy. The earlier the infection occurs, the more likely the infant is to be affected, and the more serious the abnormalities tend to be. The most common abnormalities are deafness, congenital heart disease, learning difficulties, cataracts, purpura, cerebral palsy, and bone abnormalities. About 1 in 5 affected babies dies in early infancy.
There is no specific treatment, apart from paracetamol for fever.
Treatment of rubella syndrome depends on the defects.
Rubella vaccine provides longlasting immunity to the disease; it is given in the MMR vaccine to babies aged 12–15 months, with a booster at school entry.
Rubella infection also provides immunity.
If a nonimmune pregnant woman comes into contact with a person who has rubella, passive immunization by immunoglobulin injection may help prevent infection of the fetus.... BMA Medical Dictionary
In a highly signi?cant advance in research, a scienti?c team in the United States obtained stem cells from newly formed human embryos
– donated by women who had become pregnant after successful in vitro fertilisation – and successfully cultivated these cells in the laboratory. This achievement opened the way to replicating in the laboratory, the various specialised cells that develop naturally in the body. UK government legislation constrains the use of human embryos in research (see ETHICS) and the ethical aspects of taking this stem-cell culture technique forwards will have to be resolved. Nevertheless, this discovery points the biological way to the use of genetic engineering in selecting di?erentiated specialised cells from which replacement tissues could be grown for use as transplants to rectify absent or damaged tissues in the human body.
Research into potential use of stem cells has raised expectations that in the long term they may prove to be an e?ective regenerative treatment for a wide range of disorders including PARKINSONISM, ALZHEIMER’S DISEASE, type-2 diabetes (see under DIABETES MELLITUS), myocardial infarction (see HEART, DISEASES OF), severe burns, osteoporosis (see under BONE, DISORDERS OF) and the regeneration of blood to replace the need for BONE MARROW TRANSPLANT. Recent research has shown that adult stem cells may also be stimulated to produce new cell lines. If successful, this would eliminate the need to use embryos and thus resolve existing ethical dilemmas over the use of stem cells.... Medical Dictionary

The bark gave colloturine, harman (loturine) and loturidine. Stem bark gave proanthocyanidin-3-monogluco- furanosides of 7-O-methyl-and 4'-O- methyl-leucopelargonidin. Betulinic, oleanolic, acetyl oleanolic and ellagic acids are reported from the plant.Glycosides, isolated from the ethanolic extract of the stem bark, are highly astringent and are reported to be responsible for the medicinal properties of the bark.The bark extracts have been reported to reduce the frequency and intensity of the contractions in vitro of both pregnant and non-pregnant uteri of animals. A fraction from the bark, besides showing action on uteri, was spasmogenic on various parts of the gastrointestinal tract and could be antagonized by atropine.The bark extracts were found to inhibit the growth of E. coli, Micrococcus pyogenes var. aureus, and enteric and dysenteric groups of organisms.Dosage: Stem bark—3-5 g powder; 20-30 g for decoction.
