In most people, deafness is a result of sensorineural hearing impairment, commonly known as nerve deafness. This means that the abnormality is located in the inner ear (the cochlea), in the auditory nerve, or in the brain itself. The prevalence of this type of hearing impairment rises greatly in elderly people, to the extent that more than 50 per cent of the over-70s have a moderate hearing impairment. In most cases no de?nite cause can be found, but contributory factors include excessive exposure to noise, either at work (e.g. shipyards and steelworks) or at leisure (loud music). Anyone who is exposed to gun?re or explosions is also likely to develop some hearing impairment: service personnel, for example.
Conductive hearing impairment is the other main classi?cation. Here there is an abnormality of the external or middle ear, preventing the normal transmission of sound waves to the inner ear. This is most commonly due to chronic otitis media where there is in?ammation of the middle ear, often with a perforation of the ear drum. It is thought that in the majority of cases this is a sequela of childhood middle-ear disease. Many preschool children suffer temporary hearing loss because of otitis media with e?usion (glue ear). Wax does not interfere with hearing unless it totally obstructs the ear canal or is impacted against the tympanic membrane. (See also EAR; EAR, DISEASES OF.)
Treatment Conductive hearing impairment can, in many cases, be treated by an operation on the middle ear or by the use of a hearing aid. Sensorineural hearing impairments can be treated only with a hearing aid. In the UK, hearing aids are available free on the NHS. Most NHS hearing aids are ear-level hearing aids – that is, they ?t behind the ear with the sound transmitted to the ear via a mould in the external ear. Smaller hearing aids are available which ?t within the ear itself, and people can wear such aids in both ears. The use of certain types of hearing aid may be augmented by ?ttings incorporated into the aid which pick up sound directly from television sets or from telephones, and from wire loop systems in halls, lecture theatres and classrooms. More recently, bone-anchored hearing aids have been developed where the hearing aid is attached directly to the bones of the skull using a titanium screw. This type of hearing aid is particularly useful in children with abnormal or absent ear canals who cannot therefore wear conventional hearing aids. People with hearing impairment should seek audiological or medical advice before purchasing any of the many types of hearing aid available commercially. Those people with a hearing impairment which is so profound (‘stone deaf’) that they cannot be helped by a hearing aid can sometimes now be ?tted with an electrical implant in their inner ear (a cochlear implant).
Congenital hearing loss accounts for a very small proportion of the hearing-impaired population. It is important to detect at an early stage as, if undetected and unaided, it may lead to delayed or absent development of speech. Otitis media with e?usion (glue ear) usually resolves spontaneously, although if it persists, surgical intervention has been the traditional treatment involving insertion of a ventilation tube (see GROMMET) into the ear drum, often combined with removal of the adenoids (see NOSE, DISORDERS OF). Recent studies, however, suggest that in many children these operations may provide only transient relief and make no di?erence to long-term outcome.

The start of ‘dehydration’ is signalled by a person becoming thirsty. In normal circumstances, the drinking of water will relieve thirst and serious dehydration does not develop. In a temperate climate an adult will lose 1.5 litres or more a day from sweating, urine excretion and loss of ?uid through the lungs. In a hot climate the loss is much higher – up to 10 litres if a person is doing hard physical work. Even in a temperate climate, severe dehydration will occur if a person does not drink for two or three days. Large losses of ?uid occur with certain illnesses – for example, profuse diarrhoea; POLYURIA in diabetes or kidney failure (see KIDNEYS, DISEASES OF); and serious blood loss from, say, injury or a badly bleeding ULCER in the gastrointestinal tract. Severe thirst, dry lips and tongue, TACHYCARDIA, fast breathing, lightheadedness and confusion are indicative of serious dehydration; the individual can lapse into COMA and eventually die if untreated. Dehydration also results in a reduction in output of urine, which becomes dark and concentrated.
Prevention is important, especially in hot climates, where it is essential to drink water even if one is not thirsty. Replacement of salts is also vital, and a diet containing half a teaspoon of table salt to every litre of water drunk is advisable. If someone, particularly a child, suffers from persistent vomiting and diarrhoea, rehydration therapy is required and a salt-andglucose rehydration mixture (obtainable from pharmacists) should be taken. For those with severe dehydration, oral ?uids will be insu?cient and the affected person needs intravenous ?uids and, sometimes, admission to hospital, where ?uid intake and output can be monitored and rehydration measures safely controlled.... dehydration

Doctors make the diagnosis of depression when they believe a patient to be ill with the latter condition, which may affect physical health and in some instances be life-threatening. This form of depression is common, with up to 15 per cent of the population suffering from it at any one time, while about 20 per cent of adults have ‘medical’ depression at some time during their lives – such that it is one of the most commonly presenting disorders in general practice. Women seem more liable to develop depression than men, with one in six of the former and one in nine of the latter seeking medical help.
Manic depression is a serious form of the disorder that recurs throughout life and is manifested by bouts of abnormal elation – the manic stage. Both the manic and depressive phases are commonly accompanied by psychotic symptoms such as delusions, hallucinations and a loss of sense of reality. This combination is sometimes termed a manic-depressive psychosis or bipolar affective disorder because of the illness’s division into two parts. Another psychiatric description is the catch-all term ‘affective disorder’.
Symptoms These vary with the illness’s severity. Anxiety and variable moods are the main symptoms in mild depression. The sufferer may cry without any reason or be unresponsive to relatives and friends. In its more severe form, depression presents with a loss of appetite, sleeping problems, lack of interest in and enjoyment of social activities, tiredness for no obvious reason, an indi?erence to sexual activity and a lack of concentration. The individual’s physical and mental activities slow down and he or she may contemplate suicide. Symptoms may vary during the 24 hours, being less troublesome during the latter part of the day and worse at night. Some people get depressed during the winter months, probably a consequence of the long hours of darkness: this disorder – SEASONAL AFFECTIVE DISORDER SYNDROME, or SADS – is thought to be more common in populations living in areas with long winters and limited daylight. Untreated, a person with depressive symptoms may steadily worsen, even withdrawing to bed for much of the time, and allowing his or her personal appearance, hygiene and environment to deteriorate. Children and adolescents may also suffer from depression and the disorder is not always recognised.
Causes A real depressive illness rarely has a single obvious cause, although sometimes the death of a close relative, loss of employment or a broken personal relationship may trigger a bout. Depression probably has a genetic background; for instance, manic depression seems to run in some families. Viral infections sometimes cause depression, and hormonal disorders – for example, HYPOTHYROIDISM or postnatal hormonal disturbances (postnatal depression) – will cause it. Di?cult family or social relations can contribute to the development of the disorder. Depression is believed to occur because of chemical changes in the transmission of signals in the nervous system, with a reduction in the neurochemicals that facilitate the passage of messages throughout the system.
Treatment This depends on the type and severity of the depression. These are three main forms. PSYCHOTHERAPY either on a one-to-one basis or as part of a group: this is valuable for those whose depression is the result of lifestyle or personality problems. Various types of psychotherapy are available. DRUG TREATMENT is the most common method and is particularly helpful for those with physical symptoms. ANTIDEPRESSANT DRUGS are divided into three main groups: TRICYCLIC ANTIDEPRESSANT DRUGS (amitriptyline, imipramine and dothiepin are examples); MONOAMINE OXIDASE INHIBITORS (MAOIS) (phenelzine, isocarboxazid and tranylcypromine are examples); and SELECTIVE SEROTONIN REUPTAKE INHIBITORS (SSRIS) (?uoxetine – well known as Prozac®, ?uvoxamine and paroxetine are examples). For manic depression, lithium carbonate is the main preventive drug and it is also used for persistent depression that fails to respond to other treatments. Long-term lithium treatment reduces the likelihood of relapse in about 80 per cent of manic depressives, but the margin between control and toxic side-effects is narrow, so the drug must be carefully supervised. Indeed, all drug treatment for depression needs regular monitoring as the substances have powerful chemical properties with consequential side-effects in some people. Furthermore, the nature of the illness means that some sufferers forget or do not want to take the medication. ELECTROCONVULSIVE THERAPY (ECT) If drug treatments fail, severely depressed patients may be considered for ECT. This treatment has been used for many years but is now only rarely recommended. Given under general anaesthetic, in appropriate circumstances, ECT is safe and e?ective and may even be life-saving, though temporary impairment of memory may occur. Because the treatment was often misused in the past, it still carries a reputation that worries patients and relatives; hence careful assessment and counselling are essential before use is recommended.
Some patients with depression – particularly those with manic depression or who are a danger to themselves or to the public, or who are suicidal – may need admission to hospital, or in severe cases to a secure unit, in order to initiate treatment. But as far as possible patients are treated in the community (see MENTAL ILLNESS).... depression
Causes of degeneration are, in many cases, very obscure. In some cases heredity plays a part, with particular organs – for example, the kidneys – tending to show ?broid changes in successive generations. Fatty, ?broid, and calcareous degenerations are part of the natural change in old age; defective nutrition may bring them on prematurely, as may excessive and long-continued strain upon an organ like the heart. Various poisons, such as alcohol, play a special part in producing the changes, and so do the poisons produced by various diseases, particularly SYPHILIS and TUBERCULOSIS.... degeneration
Delirium (confusion) In some old people, acute confusion is a common e?ect of physical illness. Elderly people are often referred to as being ‘confused’; unfortunately this term is often inappropriately applied to a wide range of eccentricities of speech and behaviour as if it were a diagnosis. It can be applied to a patient with the early memory loss of DEMENTIA – forgetful, disorientated and wandering; to the dejected old person with depression, often termed pseudo-dementia; to the patient whose consciousness is clouded in the delirium of acute illness; to the paranoid deluded sufferer of late-onset SCHIZOPHRENIA; or even to the patient presenting with the acute DYSPHASIA and incoherence of a stroke. Drug therapy may be a cause, especially in the elderly.
Delirium tremens is the form of delirium most commonly due to withdrawal from alcohol, if a person is dependent on it (see DEPENDENCE). There is restlessness, fear or even terror accompanied by vivid, usually visual, hallucinations or illusions. The level of consciousness is impaired and the patient may be disorientated as regards time, place and person.
Treatment is, as a rule, the treatment of causes. (See also ALCOHOL.) As the delirium in fevers is due partly to high temperature, this should be lowered by tepid sponging. Careful nursing is one of the keystones of successful treatment, which includes ensuring that ample ?uids are taken and nutrition is maintained.... delirium
Treatment If organic disease is identi?ed, it should, where possible, be treated; otherwise the treatment of dementia is alleviation of its symptoms. The affected person must be kept clean and properly fed. Good nursing care in comfortable surroundings is important and sedation with appropriate drugs may be required. Patients may eventually need institutional care. (See ALZHEIMER’S DISEASE.)... dementia
The dependence that most concerns modern society is one in which individuals become dependent on or addicted to certain substances such as alcohol, drugs, tobacco (nicotine), caffeine and solvents. This is often called substance abuse. Some people become addicted to certain foods or activities: examples of the latter include gambling, computer games and use of the Internet.
The 28th report of the World Health Organisation Expert Committee on Drug Dependence in 1993 de?ned drug dependence as: ‘A cluster of physiological, behavioural and cognitive phenomena of variable intensity, in which the use of a psychoactive drug (or drugs) takes on a high priority. The necessary descriptive characteristics are preoccupation with a desire to obtain and take the drug and persistent drug-seeking behaviour. Psychological dependence occurs when the substance abuser craves the drug’s desirable effects. Physical dependence occurs when the user has to continue taking the drug to avoid distressing withdrawal or abstinence symptoms. Thus, determinants and the problematic consequences of drug dependence may be biological, psychological or social and usually interact.’
Di?erent drugs cause di?erent rates of dependence: TOBACCO is the most common substance of addiction; HEROIN and COCAINE cause high rates of addiction; whereas ALCOHOL is much lower, and CANNABIS lower again. Smoking in the western world reached a peak after World War II with almost 80 per cent of the male population smoking. The reports on the link between smoking and cancer in the early 1960s resulted in a decline that has continued so that only around a quarter of the adult populations of the UK and USA smokes. Globally, tobacco consumption continues to grow, particularly in the developing world with multinational tobacco companies marketing their products aggressively.
Accurate ?gures for illegal drug-taking are hard to obtain, but probably approximately 4 per cent of the population is dependent on alcohol and 2 per cent on other drugs, both legal and illegal, at any one time in western countries.
How does dependence occur? More than 40 distinct theories or models of drug misuse have been put forward. One is that the individual consumes drugs to cope with personal problems or diffculties in relations with others. The other main model emphasises environmental in?uences such as drug availability, environmental pressures to consume drugs, and sociocultural in?uences such as peer pressure.
By contrast to these models of why people misuse drugs, models of compulsive drug use – where individuals have a compulsive addiction
– have been amenable to testing in the laboratory. Studies at cellular and nerve-receptor levels are attempting to identify mechanisms of tolerance and dependence for several substances. Classical behaviour theory is a key model for understanding drug dependence. This and current laboratory studies are being used to explain the reinforcing nature of dependent substances and are helping to provide an explanatory framework for dependence. Drug consumption is a learned form of behaviour. Numerous investigators have used conditioning theories to study why people misuse drugs. Laboratory studies are now locating the ‘reward pathways’ in the brain for opiates and stimulants where positive reinforcing mechanisms involve particular sectors of the brain. There is a consensus among experts in addiction that addictive behaviour is amenable to e?ective treatment, and that the extent to which an addict complies with treatment makes it possible to predict a positive outcome. But there is a long way to go before the mechanisms of drug addiction are properly understood or ways of treating it generally agreed.
Effects of drugs Cannabis, derived from the plant Cannabis sativa, is a widely used recreational drug. Its two main forms are marijuana, which comes from the dried leaves, and hashish which comes from the resin. Cannabis may be used in food and drink but is usually smoked in cigarettes to induce relaxation and a feeling of well-being. Heavy use can cause apathy and vagueness and may even cause psychosis. Whether or not cannabis leads people to using harder drugs is arguable, and a national debate is underway on whether its use should be legalised for medicinal use. Cannabis may alleviate the symptoms of some disorders – for example, MULTIPLE SCLEROSIS (MS) – and there are calls to allow the substance to be classi?ed as a prescribable drug.
About one in ten of Britain’s teenagers misuses volatile substances such as toluene at some time, but only about one in 40 does so regularly. These substances are given o? by certain glues, solvents, varnishes, and liquid fuels, all of which can be bought cheaply in shops, although their sale to children under 16 is illegal. They are often inhaled from plastic bags held over the nose and mouth. Central-nervous-system excitation, with euphoria and disinhibition, is followed by depression and lethargy. Unpleasant effects include facial rash, nausea and vomiting, tremor, dizziness, and clumsiness. Death from COMA and acute cardiac toxicity is a serious risk. Chronic heavy use can cause peripheral neuropathy and irreversible cerebellar damage. (See SOLVENT ABUSE (MISUSE).)
The hallucinogenic or psychedelic drugs include LYSERGIC ACID DIETHYLAMIDE (LSD) or acid, magic mushrooms, ecstasy (MDMA), and phencyclidine (PCP or ‘angel’ dust, mainly used in the USA). These drugs have no medicinal uses. Taken by mouth, they produce vivid ‘trips’, with heightened emotions and perceptions and sometimes with hallucinations. They are not physically addictive but can cause nightmarish bad trips during use and ?ashbacks (vivid reruns of trips) after use, and can probably trigger psychosis and even death, especially if drugs are mixed or taken with alcohol.
Stimulant drugs such as amphetamine and cocaine act like adrenaline and speed up the central nervous system, making the user feel con?dent, energetic, and powerful for several hours. They can also cause severe insomnia, anxiety, paranoia, psychosis, and even sudden death due to convulsions or tachycardia. Depression may occur on withdrawal of these drugs, and in some users this is su?ciently deterrent to cause psychological dependence. Amphetamine (‘speed’) is mainly synthesised illegally and may be eaten, sni?ed, or injected. Related drugs, such as dexamphetamine sulphate (Dexedrine), are prescribed pills that enter the black market. ECSTASY is another amphetamine derivative that has become a popular recreational drug; it may have fatal allergic effects. Cocaine and related drugs are used in medicine as local anaesthetics. Illegal supplies of cocaine (‘snow’ or ‘ice’) and its derivative, ‘crack’, come mainly from South America, where they are made from the plant Erythroxylon coca. Cocaine is usually sni?ed (‘snorted’) or rubbed into the gums; crack is burnt and inhaled.
Opiate drugs are derived from the opium poppy, Papaver somniferum. They are described as narcotic because they induce sleep. Their main medical use is as potent oral or injectable analgesics such as MORPHINE, DIAMORPHINE, PETHIDINE HYDROCHLORIDE, and CODEINE. The commonest illegal opiate is heroin, a powdered form of diamorphine that may be smoked, sni?ed, or injected to induce euphoria and drowsiness. Regular opiate misuse leads to tolerance (the need to take ever larger doses to achieve the same e?ect) and marked dependence. A less addictive oral opiate, METHADONE HYDROCHLORIDE, can be prescribed as a substitute that is easier to withdraw.
Some 75,000–150,000 Britons now misuse opiates and other drugs intravenously, and pose a huge public-health problem because injections with shared dirty needles can carry the blood-borne viruses that cause AIDS/HIV and HEPATITIS B. Many clinics now operate schemes to exchange old needles for clean ones, free of charge. Many addicts are often socially disruptive.

Individuals with dementia suffer a gradual deterioration of memory and of the ability to grasp what is happening around them. They often cover up their early failings and the condition may ?rst become apparent as a result of emotional outbursts or uncharacteristic behaviour in public. Eventually personal habits and speech deteriorate and they become thoroughly confused and di?cult to look after. Treatment is primarily a matter of ameliorating the symptoms, coupled with a sympathetic handling of the sufferer and the relatives. Admission to hospital or nursing home may be necessary if relatives are unable to look after the patient at home. (See also MEDICINE OF THE AGEING.)... senile dementia

Delays vary in severity and may affect the development of hand–eye coordination, walking, listening, language, speech, or social interaction. Delay may first be noticed by parents or detected during a routine developmental check.
There are many causes of developmental delay. A child who is late in most aspects of development usually has a generalized problem. This may be due to severe visual or hearing impairment, limited intellectual abilities (see learning difficulties), or damage to the brain before, during, or after birth.
Specific areas of delay may occur in movement and walking. Often there is no serious cause. However, specific causes may include muscular dystrophy and spina bifida. Delay in developing manipulative skills is often due to lack of adequate stimulation.
A lack of response to sound may be due to deafness. Autism is a rare cause of unresponsiveness to the human voice although hearing is normal. A hearing problem may cause delayed speech. Twins are often late talkers. Any generalized difficulty with muscle control can affect speech production; this may occur in children with cerebral palsy. Damage to, or structural defects of, the speech muscles, larynx (voice box), or mouth may also cause speech difficulties, as may any disorder affecting the speech area of the brain (see aphasia; dysarthria; dysphonia; speech disorders). Delay in bladder and bowel control have many possible causes (see encopresis; enuresis; soiling).

(CCRAS.)... ceratophyllum demersumBarrel chest is found in long-standing ASTHMA or chronic BRONCHITIS and EMPHYSEMA, when the lungs are chronically enlarged. The anterio-posterior dimension of the chest is increased and the ribs are near horizontal. In this position they can produce little further expansion of the chest, and breathing often relies on accessory muscles in the neck lifting up the whole thoracic cage on inspiration.
Pigeon chest is one in which the cross-section of the chest becomes triangular with the sternum forming a sort of keel in front. It may be related to breathing problems in early life.
Rickety chest is uncommon now and is caused by RICKETS in early life. There is a hollow down each side caused by the pull of muscles on the softer ribs in childhood. The line of knobs produced on each side where the ribs join their costal cartilages is known as the rickety rosary.
Pectus excavatum, or funnel chest, is quite a common abnormality where the central tendon of the diaphragm seems to be too short so that the lower part of the sternum is displaced inwards and the lower ribs are prominent. When severe, it may displace the heart further to the left side.
Local abnormalities in the shape of the chest occur when there is a deformity in the spine such as scoliosis which alters the angles of the ribs. The chest wall may be locally ?attened when the underlying lung is reduced in size locally over a prolonged period. (See SPINE AND SPINAL CORD, DISEASES AND INJURIES OF.) This may be seen over a scarred area of lung such as that observed in pulmonary TUBERCULOSIS.... chest, deformities of

Special needs The Children Act 1989, Education Acts 1981, 1986 and 1993, and the Chronically Sick and Disabled Persons Legislation 1979 impose various statutory duties to identify and provide assistance for children with special needs. They include the chronically ill as well as those with impaired development or disabilities such as CEREBRAL PALSY, or hearing, vision or intellectual impairment. Many CDTs keep a register of such children so that services can be e?ciently planned and evaluated. Parents of disabled children often feel isolated and neglected by society in general; they are frequently frustrated by the lack of resources available to help them cope with the sheer hard work involved. The CDT, through its key workers, does its best to absorb anger and divert frustration into constructive actions.
There are other groups of children who come to the attention of child health services. Community paediatricians act as advisers to adoption and fostering agencies, vital since many children needing alternative homes have special medical or educational needs or have behavioural or psychiatric problems. Many see a role in acting as advocates, not just for those with impairments but also for socially disadvantaged children, including those ‘looked after’ in children’s homes and those of travellers, asylum seekers, refugees and the homeless.
Child protection Regrettably, some children come to the attention of child health specialists because they have been beaten, neglected, emotionally or nutritionally starved or sexually assaulted by their parents or carers. Responsibility for the investigation of these children is that of local-authority social-services departments. However, child health professionals have a vital role in diagnosis, obtaining forensic evidence, advising courts, supervising the medical aspects of follow-up and teaching doctors, therapists and other professionals in training. (See CHILD ABUSE.)
School health services Once children have reached school age, the emphasis changes. The prime need becomes identifying those with problems that may interfere with learning – including those with special needs as de?ned above, but also those with behavioural problems. Teachers and parents are advised on how to manage these problems, while health promotion and health education are directed at children. Special problems, especially as children reach secondary school (aged 11–18) include accidents, substance abuse, psychosexual adjustment, antisocial behaviour, eating disorders and physical conditions which loom large in the minds of adolescents in particular, such as ACNE, short stature and delayed puberty.
There is no longer, in the UK, a universal school health service as many of its functions have been taken over by general practitioners and hospital and community paediatricians. However, most areas still have school nurses, some have school doctors, while others do not employ speci?c individuals for these tasks but share out aspects of the work between GPs, health visitors, community nurses and consultant paediatricians in child health.
Complementing their work is the community dental service whose role is to monitor the whole child population’s dental health, provide preventive programmes for all, and dental treatment for those who have di?culty using general dental services – for example, children with complex disability. All children in state-funded schools are dentally screened at ages ?ve and 15.
Successes and failures Since the inception of the NHS, hospital services for children have had enormous success: neonatal and infant mortality rates have fallen by two-thirds; deaths from PNEUMONIA have fallen from 600 per million children to a handful; and deaths from MENINGITIS have fallen to one-?fth of the previous level. Much of this has been due to the revolution in the management of pregnancy and labour, the invention of neonatal resuscitation and neonatal intensive care, and the provision of powerful antibiotics.
At the same time, some children acquire HIV infection and AIDS from their affected mothers (see AIDS/HIV); the prevalence of atopic (see ATOPY) diseases (ASTHMA, eczema – see DERMATITIS, HAY FEVER) is rising; more children attend hospital clinics with chronic CONSTIPATION; and little can be done for most viral diseases.
Community child health services can also boast of successes. The routine immunisation programme has wiped out SMALLPOX, DIPHTHERIA and POLIOMYELITIS and almost wiped out haemophilus and meningococcal C meningitis, measles and congenital RUBELLA syndrome. WHOOPING COUGH outbreaks continue but the death and chronic disability rates have been greatly reduced. Despite these huge health gains, continuing public scepticism about the safety of immunisation means that there can be no relaxation in the educational and health-promotion programme.
Services for severely and multiply disabled children have improved beyond all recognition with the closure of long-stay institutions, many of which were distinctly child-unfriendly. Nonetheless, scarce resources mean that families still carry heavy burdens. The incidence of SUDDEN INFANT DEATH SYNDROME (SIDS) has more than halved as a result of an educational programme based on ?rm scienti?c evidence that the risk can be reduced by putting babies to sleep on their backs, avoidance of parental smoking, not overheating, breast feeding and seeking medical attention early for illness.
Children have fewer accidents and better teeth but new problems have arisen: in the 1990s children throughout the developed world became fatter. A UK survey in 2004 found that one in ?ve children are overweight and one in 20 obese. Lack of exercise, the easy availability of food at all times and in all places, together with the rise of ‘snacking’, are likely to provoke signi?cant health problems as these children grow into adult life. Adolescents are at greater risk than ever of ill-health through substance abuse and unplanned pregnancy. Child health services are facing new challenges in the 21st century.... child development teams (cdts)

When a death occurs at sea, the captain of the ship has authority to permit burial at sea. If, however, there are any doubts about cause of death, the captain may decide to preserve the body and refer the case to the relevant authorities at the next port of call.
Embalming is still used occasionally. The process consists in removing the internal organs through small openings, and ?lling the body cavities with various aromatics of antiseptic power – the skin being swathed in bandages or otherwise protected from the action of the air. Bodies are also preserved by injecting the blood vessels with strong antiseptics such as perchloride of mercury.
Cremation or incineration of the body is now the commonest method of disposal of the dead in the UK, where land for burials is increasingly scarce; today it accounts for around 75 per cent of disposals. The process of incineration takes 1–2 hours. Something in the range of 2·3 to 3·2 kg (5–7 lbs) of ash result from the combustion of the body, and there is no admixture with that from the fuel.
Cremation of a body means that it is almost impossible to conduct any meaningful forensic tests should any subsequent doubts be raised about the cause of death. So, before cremation can take place, two doctors have to sign the cremation forms. The ?rst is usually the doctor who was caring for the patient at the time of death – an important exception being cases of sudden death, when the coroner holds an inquest into the cause and authorises the necessary approval for cremation. In 1999, fewer than 3,500 deaths were certi?ed following a post-mortem, out of a total number of deaths in England and Wales of more than 556,000. When the coroner is not involved, the second doctor must have been quali?ed for ?ve years; he or she must be unconnected with the patient’s care and not linked professionally with the ?rst doctor. (For example, if the ?rst doctor is a general practitioner – as in the majority of cases they are – the second doctor should be from another practice.) Before signing the cremation certi?cate the second doctor must conduct an external examination of the dead person and discuss the circumstances of death with the ?rst doctor.
The two cremation forms are then inspected by crematorium medical referees who must be satis?ed that the cause of death has de?nitely been ascertained. The present death and cremation certi?cation system has been in place in the UK for many years – the legislative framework for cremation was set up in 1902 – and death certi?cation procedures were last reviewed by the government-appointed Brodrick committee in 1971, with no fundamental changes proposed. The case of Harold Shipman, a general practitioner convicted of murdering more than 15 patients, and suspected of murdering many more, has revealed serious weaknesses in the certi?cation system. A comprehensive review of the present procedures was in place at the time of writing (2004).... dead, disposal of the

The two most common causes of death in the UK are diseases of the circulatory system (including strokes and heart disease) and cancer.
Overall annual death rates among women in the UK at the start of the 21st century were
7.98 per 1,000 population, and among men,
5.58 per 1,000. Comparable ?gures at the start of the 20th century were 16.3 for women and
18.4 for men. The death rates in 1900 among infants up to the age of four were 47.9 per 1,000 females and 57 per 1,000 males. By 2003 these numbers had fallen to 5.0 and 5.8 respectively. All these ?gures give a crude indication of how the health of Britain’s population has improved in the past century.
Death rates and ?gures on the causes of deaths are essential statistics in the study of EPIDEMIOLOGY which, along with information on the incidence of illnesses and injuries, provides a temporal and geographical map of changing health patterns in communities. Such information is valuable in planning preventive health measures (see PUBLIC HEALTH) and in identifying the natural history of diseases – knowledge that often contributes to the development of preventive measures and treatments for those diseases.... death, causes of
The only certain sign of death, however, is that the heart has stopped beating. To ensure that this is permanent, it is necessary to listen over the heart with a stethoscope, or directly with the ear, for at least ?ve minutes. Permanent stoppage of breathing should also be con?rmed by observing that a mirror held before the mouth shows no haze, or that a feather placed on the upper lip does not ?utter.
In the vast majority of cases there is no dif?culty in ensuring that death has occurred. The introduction of organ transplantation, however, and of more e?ective mechanical means of resuscitation, such as ventilators, whereby an individual’s heart can be kept beating almost inde?nitely, has raised diffculties in a minority of cases. To solve the problem in these cases the concept of ‘brain death’ has been introduced. In this context it has to be borne in mind that there is no legal de?nition of death. Death has traditionally been diagnosed by the irreversible cessation of respiration and heartbeat. In the Code of Practice drawn up in 1983 by a Working Party of the Health Departments of Great Britain and Northern Ireland, however, it is stated that ‘death can also be diagnosed by the irreversible cessation of brain-stem function’. This is described as ‘brain death’. The brain stem consists of the mid-brain, pons and medulla oblongata which contain the centres controlling the vital processes of the body such as consciousness, breathing and the beating of the heart (see BRAIN). This new concept of death, which has been widely accepted in medical and legal circles throughout the world, means that it is now legitimate to equate brain death with death; that the essential component of brain death is death of the brain stem; and that a dead brain stem can be reliably diagnosed at the bedside. (See GLASGOW COMA SCALE.)
Four points are important in determining the time that has elapsed since death. HYPOSTASIS, or congestion, begins to appear as livid spots on the back, often mistaken for bruises, three hours or more after death. This is due to the blood running into the vessels in the lowest parts. Loss of heat begins at once after death, and the body has become as cold as the surrounding air after 12 hours – although this is delayed by hot weather, death from ASPHYXIA, and some other causes. Rigidity, or rigor mortis, begins in six hours, takes another six to become fully established, remains for 12 hours and passes o? during the succeeding 12 hours. It comes on quickly when extreme exertion has been indulged in immediately before death; conversely it is slow in onset and slight in death from wasting diseases, and slight or absent in children. It begins in the small muscles of the eyelid and jaw and then spreads over the body. PUTREFACTION is variable in time of onset, but usually begins in 2–3 days, as a greenish tint over the abdomen.... death, signs of

This contrasts with 10 per cent during the service’s early years, when the NHS was coping with decades of ‘dental neglect’. The population’s dental health has, however, been steadily improving: in 1968 more than one-third of people had no natural teeth; by the late 1990s the proportion had fallen to 13 per cent.
Dentistry is divided into several groupings.
General dental practitioners Concerned with primary dental care, the prevention, diagnosis and treatment of diseases of the gums and teeth – for example, caries (see TEETH, DISORDERS OF). They also deal with diffculties in biting and the effects of trauma, and are aware that oral disorders may re?ect disease elsewhere in the body. They will refer to the hospital dental services, patients who require treatment that cannot be satisfactorily carried out in a primary-care setting.
Most routine dental prevention and treatment is carried out in general dental practitioners’ surgeries, where the dentists also supervise the work of hygienists and dental auxiliaries. Appliances, such as dentures, crowns, bridges and orthodontic appliances are constructed by dental technicians working in dental laboratories.
There are around 18,800 dentists providing general dental services in the UK. These practitioners are free to accept or reject any potential patient and to practise where they wish. Those dentists treating patients under an NHS contract (a mixture of capitation fees and items of service payments) can also treat patients privately (for an appropriate fee). Some dentists opt for full-time private practice, and their numbers are increasing in the wake of changes in 1990 in the contracts of NHS general dental practitioners.
Community dental practitioner Part of the public-health team and largely concerned with monitoring dental health and treating the young and the handicapped.
In the hospitals and dental schools are those who are involved in only one of the specialities.
Around 2,800 dentists work in NHS hospitals and 1,900 in the NHS’s community services. In some parts of the UK, people wanting NHS treatment are having diffculties ?nding dentists willing to provide such care.
Restorative dentist Concerned with the repair of teeth damaged by trauma and caries, and the replacement of missing teeth.

The cause of developmental hip dysplasia is not known, although it is more common in girls, especially babies born by breech delivery or following pregnancies in which the amount of amniotic fluid was abnormally small.
If dislocation is detected in early infancy, splints are applied to the thigh to manoeuvre the ball of the joint into the socket and keep it in position. These are worn for about 3 months and usually correct the problem. Progress may be monitored by ultrasound scanning and X-rays. Corrective surgery may also be required.
If treatment is delayed, there may be lifelong problems with walking. Without treatment, the dislocation often leads to shortening of the leg, limping, and early osteoarthritis in the joint.... developmental hip dysplasia

Unfortunately these ‘biological’ detergents may cause dermatitis. In addition, they have been reported to cause asthma in those using them, and even more so in workers manufacturing them.... detergents

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

The affected tooth aches or throbs, and biting or chewing is usually extremely painful. The gum around the tooth is tender and may be red and swollen. An untreated abscess eventually erodes a sinus (channel) through the jawbone to the gum surface, where it forms a swelling known as a gumboil. As the abscess spreads, the glands in the neck and the side of the face may become swollen, and fever may develop. Treatment may consist of draining the abscess, followed by root-canal treatment of the affected tooth, but in some cases extraction of the tooth is necessary. Antibiotics are prescribed if the infection has spread beyond the tooth.

Although there is wide variation in individual rates of progress, most children develop certain skills within predictable age ranges.
For example, most infants start to walk at 12–18 months.
Capability for new skills is linked to the maturity of the child’s nervous system.
Individual rates of maturity are determined genetically and modified by environmental factors in the uterus and after birth.
Development is assessed in early childhood by looking at abilities in 4 main areas: locomotion; hearing and speech; vision and fine movement; and social behaviour and play.

Most congenital deformities are relatively rare.
Among the more common are club-foot (talipes) and cleft lip and palate.
Injuries that can cause deformity include burns, torn muscles, and broken bones.
Disorders that may cause deformity include nerve problems, some deficiencies, such as rickets, and Paget’s disease of the bone.
Disuse of a part of the body can lead to deformity through stiffening and contracture of unused muscles or tendons.
Many deformities can be corrected by orthopaedic techniques, plastic surgery, or exercise.... deformity
During a routine dental examination, the dentist uses a metal instrument to
probe for dental cavities, chipped teeth, or fillings. Dental X-rays are sometimes carried out to check for problems that may not be visible. Dentists also check how well the upper and lower teeth come together. Regular examinations in children enable the monitoring of the replacement of primary teeth by permanent, or secondary, teeth. Referral for orthodontic treatment may be made. dental extraction See tooth extraction. dental X-ray An image of the teeth and jaws that provides information for detecting, diagnosing, and treating conditions that can threaten oral and general health.

Periapical X-rays are taken using X-ray film held behind the teeth. They give detailed images of whole teeth and the surrounding tissues. They show unerupted or impacted teeth, root fractures, abscesses, cysts, and tumours, and can help diagnose some skeletal diseases. Bite-wing X-rays show the crowns of the teeth and can detect areas of decay and changes in bone due to periodontal disease. Panoramic X-rays show all the teeth and surrounding structures on one large film. They can show unerupted or impacted teeth, cysts, jaw fractures, or tumours. The amount of radiation received from dental X-rays is extremely small. However, dental X-rays should be avoided during pregnancy.... dental examination
outer surfaces of the front teeth is most frequently caused by excessive intake of fruit juices and carbonated drinks. Erosion of the inner surfaces of the molars may be a result of the regurgitation of stomach acid, as occurs in people suffering from acid reflux or bulimia. (See also caries, dental.)... erosion, dental
There is a widespread rash with severe flaking of the skin, which results in increased loss of water and protein from the surface of the body.
Protein loss may cause oedema and muscle wasting.
Further possible complications include heart failure and infection.
The treatment and outlook depend on the cause.... exfoliative dermatitis
For most extractions, local anaesthesia is used (see anaesthesia, dental). Teeth are usually extracted with dental forceps, which grasp the root of the tooth. In difficult extractions, some gum and bone may also need to be removed from around the tooth.... extraction, dental

the mother is unable to push out her baby unaided, or if the baby is showing signs of fetal distress. Forceps are also used to control the head once the body has been delivered in breech delivery to prevent too rapid a birth.An episiotomy (making of a cut in the perineum) is usually needed for a forceps delivery. Recovery and care for mother and child is usually the same as after a vaginal delivery.... forceps delivery
Fractures may involve the crown or the root of a tooth, or both.
Fractures of the enamel can usually be repaired by bonding (see bonding, dental); in some cases, a replacement crown may be fitted (see crown, dental).
Pulpotomy may be performed if the pulp of a tooth is damaged.
Fractures of the root may be treated by splinting (see splinting, dental), root-canal treatment, or removing the tooth (see extraction, dental).... fracture, dental
Impacted wisdom teeth are common, and, if symptomless, may not need to be removed.
In some cases, however, symptoms necessitate their removal.... impaction, dental
A quick-setting material, such as alginate, is placed in a mould over the teeth.
The mould is removed, and plaster of Paris is poured into it to obtain a model of the area.
This model is then used as a base on which to build a denture, bridge, or dental inlay.
Dental impressions are also used in orthodontics to study the position of the teeth and to make orthodontic appliances to correct irregularities.... impression, dental

Lactase deficiency results in a reduced ability to digest lactose, also known as lactose intolerance.
The condition may be permanent, or may occur temporarily after gastroenteritis, particularly in young children.
Symptoms include abdominal cramps, bloating, flatulence, and diarrhoea, all of which are caused by the laxative effect of the undigested sugar in the intestines.
Treatment is with a lactose-free diet.... lactase deficiency
Limb defects are rare and may be inherited or form part of a syndrome.
In a condition called phocomelia, hands, feet, or tiny finger- or toe-buds are attached to limb stumps or grow directly from the trunk.
The sedative drug thalidomide, when taken by pregnant women, is known to have caused phocomelia in fetuses.... limb defects
Abnormalities in brain biochemistry, or in the structure and/or function of certain nerve pathways within the brain, could underlie manic–depressive illness. An inherited tendency is also an established causative factor.Severe manic–depressive illness often needs hospital treatment. Antidepressant drugs and/or ECT are used to treat depression, and antipsychotic drugs are given to control manic symptoms. Carbamazepine or lithium may be used to prevent relapse.
Group therapy, family therapy, and individual psychotherapy may be useful in treatment. Cognitive–behavioural therapy may also be helpful. With treatment, more than 80 per cent of patients improve or remain stable. Even those with severe illness may be restored to near normal health with lithium.... manic–depressive illness
Typically, a child shows hostile, argumentative behaviour that includes loss of temper, defiance of rules, and swearing.
To some extent such behaviour is common in adolescence, but when law-breaking or violence occur the condition is deemed to be pathological.... oppositional defiant disorder
It is the chief cause of tooth decay (see caries, dental) and gingivitis, and forms the basis of a hard deposit (see calculus, dental).
Some of the microorganisms in plaque, particularly STREPTOCOCCUS MUTANS, break down sugar in the remains of carbohydrate food that sticks to the mucus, creating an acid that can erode tooth enamel.... plaque, dental

There are different forms of spina bifida. In spina bifida occulta, the only defect is a failure of the fusion of the bony arches behind the spinal cord, which may not cause any problems. When the bone defect is more extensive, there may be a meningocele, a protrusion of the meninges, or a myelomeningocele, a malformation of the spinal cord. Myelomeningocele is likely to cause severe handicap, with paralysis of the legs, loss of sensation in the lower body, hydrocephalus, and paralysis of the anus and bladder, causing incontinence. Associated problems include cerebral palsy, epilepsy, and mental handicap.
Surgery is usually performed a few days after birth. In mild cases, the defect can usually be corrected, but in myelomeningocele, some handicap will remain.
Genetic factors play a part in neural tube defects, which show multifactorial inheritance. Couples who have had an affected child or who have a family history of neural tube defects should seek genetic counselling. The risk of a neural tube defect occurring can be substantially reduced if the mother takes folic acid supplements for a month before conception and during the early part of the pregnancy.
Ultrasound scanning and amniocentesis allow accurate antenatal testing for neural tube defects.... neural tube defect
Overcrowded teeth may lead to malocclusion or may prevent certain teeth from erupting through the gum (see impaction, dental). They can be difficult to clean, increasing the risk of dental decay (see caries, dental) and periodontal disease.
Teeth may need to be extracted to allow room for others. Usually an orthodontic appliance is fitted to the remaining teeth to position them correctly.... overcrowding, dental

Chromosomal abnormalities or hormonal defects can lead to ambiguous sex (see genitalia, ambiguous), although true hermaphroditism is rare.... sex determination
Irritability and a shortened attention span may occur after a short night’s sleep.
Longer periods without sleep leave a person increasingly unable to concentrate or perform normal tasks.
Three or more sleepless nights may lead to hallucinations and, in some cases, to paranoia.... sleep deprivation
A diagnosis is made by doppler ultrasound scanning.
Treatment depends on the site and extent of the clots.
Small clots may not need treatment if they are confined to the calf and the patient is mobile.
Otherwise, anticoagulant drugs or thrombolytic drugs are given.
If there is a high risk of a pulmonary embolism, thrombectomy may be performed.... thrombosis, deep vein

SYNONYMS: Trilisa odoratissima, Liatris odoratissima, Frasera speciosa, hound’s tongue, deer’s tongue, Carolina vanilla, vanilla leaf, wild vanilla, vanilla trilisa, whart’s tongue, liatrix (oleoresin or absolute).
GENERAL DESCRIPTION: A herbaceous perennial plant distinguished by a naked receptacle and feathery pappus, with large, fleshy, dark green leaves, clasped at the base. When fresh, the leaves have little odour but when dried they acquire a vanilla-like odour, largely due to the coumarin that can be seen in crystals on the upper sides of the leaves.
DISTRIBUTION: Native to eastern USA; gathered on the savannah land between North Carolina and Florida.
OTHER SPECIES: There are several species of deertongue native to America, for example blazing star or prairie pine (Liatris squarrosa), and gayfeather (L. spicata). Not to be confused with the common vanilla (Vanilla planifolia) or with the European hound’s tongue (Cynoglossum officinale), all of which have been used in herbal medicine.
HERBAL/FOLK TRADITION: The roots have been used for their diuretic effects, and applied locally for sore throats and gonorrhoea. It has also been used as a tonic in treating malaria. In folklore the plant is associated with contraception and sterility in women.
ACTIONS: Antiseptic, demulcent, diaphoretic, diuretic, febrifuge, stimulant, tonic.
EXTRACTION: Oleoresin by solvent extraction from the dried leaves.
CHARACTERISTICS: A dark green, heavy, viscous liquid with a rich, herbaceous, new-mown hay scent. It blends well with oakmoss, labdanum, lavandin, frankincense, clove, patchouli and oriental-type fragrances.
PRINCIPAL CONSTITUENTS: Mainly coumarin (1.6 per cent), with dihydrotoumarin and terpenes, aldehydes and ketones.
SAFETY DATA: ‘Coumarin has toxic properties including liver injury and haemorrhages.’. (There is also the possibility of dermal irritation and phototoxicity due to the lactones present.)
AROMATHERAPY/HOME: USE None.
OTHER USES: The oleoresin is used as a fixative and fragrance component in soaps, detergents and perfumery work. Used for flavouring tobacco and; also employed for the isolation of coumarin.... deertongue
