Chemical analysis showed that they consisted of carbon treatment 3rd degree hemorrhoids discount 625mg co-amoxiclav amex, hydrogen medications and grapefruit juice cheap co-amoxiclav 625mg on-line, oxygen 6 mp treatment buy co-amoxiclav in united states online, and nitrogen and the proportions of these elements differed significantly in different alkaloids treatment 5th metacarpal fracture discount co-amoxiclav 625 mg overnight delivery. But the structure of complex carbon com pounds the way the numerous atoms were joined to each other was not under stood until well on in the nineteenth century. His one-time assistant at the College de France, Claude Bernard (see page 181) who took over Magendie’s job in 1852, did more towards explaining exactly how drugs acted. Bernard showed that certain drugs acted at strictly localized and well-defined sites, a profoundly important fact that began to displace vaguer notions that drugs had some sort of general influence throughout the body. He discovered that the poison used by South American Indians called curare (a tree resin) works where a nerve joins the muscle on which it acts, and nowhere else. It prevents the nerve impulse from making the muscle contract, and so causes paral ysis as long as the curare persists. Injected into an animal on the tip of an arrow, for instance the poison is carried by the bloodstream to all the muscles of the body and causes paralysis and death when the muscles of respiration are made inactive. The discovery paved the way to the chemical understanding that Antoine Lavoisier had foreshadowed a century earlier. The amount of opium taken, to burial chambers in Granada believed to be 5,000 years old, relieve the wear and tear of authorship was, he said, and the plant was important in the medicine of ancient civ greater than most people had any conception of, and all ilizations in Babylonia, Egypt, Rome, and Greece. Extensive seventeenth-century English physician Thomas Sydenham legal controls have been applied to the drug, and been commended its use and it became an important remedy for extensively defied by traders, governments, and consumers. Simple chemical period such as de Quincey and Coleridge were not excep treatment of morphine converts it to diamorphine or tional except in degree. Opium was widely smoked in China and other oriental nations for therapeutic and recreational reasons. When the Chinese government attempted to stop the trade in the 1840s, Britain went to war in defence of ‘free’ trade. The scenes in an opium factory in India (opposite) appeared in the Graphic in 1882. These specific structures or sub stances, of then unknown composition, came to be called ‘receptors’, and the study of drug receptors became a mainspring of fundamental pharmacology. So the reactions of drugs with bodily constituents began to be seen to be chemical events, best understood in terms of chemical knowledge. These, however, were the ideas of the laboratory scientist, and only the wisest doctors of the time saw how important the science of chemistry was becoming to the practice of medicine. One who did was Sir William Osier, a Canadian who graduated at McGill Medical School in Montreal, became professor of medicine at Johns Hopkins University in Baltimore (see page 182), and built up the first orga nized clinical unit in any Anglo-Saxon country. In his address to McGill University in 1894, he commented: ‘the physician without physiology and chemistry flounders along in an aimless fashion, never able to gain any accurate conception of disease, practising a sort of popgun pharmacy, hitting now the malady and again the patient, he himself not knowing which’. It is a curiosity of history that the first chair of pharmacology was established, not in France, Germany, or Britain, but in the university at Dorpat, now called Tartu, in Estonia. It had strong links with Germany, and recruited from Leipzig an able young doctor, Rudolph Buchheim, who had already translated the classic English textbook on pharmacology Jonathan Pereiras the Elements of M ateria Medica and Therapeutics (1839-40). His pupil, Oswald Schmiedeberg, succeeded him, and, in 1872, moved to a new department at Strasbourg. There he attracted many young doctors and scientists, who later left to develop the subject in other parts of the world. Scottish medical schools had a strong tradition of teaching ‘materia medica’, largely as a branch of botany, and the departments of materia medica were well placed to take up the new science of pharmacology under the old name. These academic departments were mainly concerned with medicinal plants, and began isolating their active constituents and discovering exactly how they worked, in terms of the growing knowledge of normal physiology. Robert Christison, a med ical professor in Edinburgh from 1822 to 1877, wrote a textbook on poisons and described experiments on his own heart and blood vessels with a poisonous bean from Calabar in West Africa, noting the muscular weakness or paralysis that the Drug Treatment and the Rise of Pharmacology 261 Help for headaches and fever the aspirin family of medicines, introduced by the German ever, was this compound checked for antirheumatic effects. Their work, published in 1899, the laboratory as by-products of coal-tar distillation. They showed that the compound was indeed effective in control included phenazone (Antipyrine), acetanilide (Antifebrine), ling pain and inflammation both in rheumatism and other and phenacetin. Bayer patented the city in animals were, by modern standards, almost non-exis production process, and named the new drug Aspirin. However, several had ognized as a useful medicine may seem surprising, but not longer lives. It is difficult, tedious, and not without risk to dis acetanilide, was first used medically in 1893 and became cover whether a substance has unpredicted medical proper a popular over-the-counter-painkiller (bufferin, aceta ties, and the odds against any particular compound being minophen, etc. Aspirin became probably the most started to fall into disrepute in the 1930s but was eventually widely used of all synthetic medicaments in the Western replaced by the related compound phenylbutazone. This was world, and nowadays competes for favour with paracetamol, introduced in 1949 but became increasingly unpopular, the chief survivor of the coal-tar antipyretic especially in the 1980s. In 1838, salicyclic acid was manufactured from salicin, today, including an ingredient of willow bark (see page 252) and used to heroin, were freely relieve fever and rheumatic pain. Fifteen years later, a rela on sale around 1900 tive of salicin, acetylsalicyclic acid, was synthesized by the when this advertise German chemist Charles Gerhardt. His successor, Thomas Fraser, isolated the bean’s active constituent an alkaloid, which he named eserine. At the Royal College of Chemistry in London, an ambitious young student, William Henry Perkin, noted that quinine was described as C20H24N2O2. He thought of a simple reaction by which it could be synthesized by oxidizing allyltoluidine, a compound available to him. The attempt produced a coloured precip itate, certainly not quinine but exciting enough to suggest further experiments, 262 The Cam bridge Illustrated H istory of M edicine the properties of anaesthetics were in part found out by accident, as is indicated in this rendering of the discov ery of chloroform by the Scottish obstetrician James Young Simpson on 4 November L847. Aged only 18, Perkin realized that one of them might do as a dye, and with great persistence he arranged for the material, called mauveine, to be made on a larger sale, and, finally, marketed. Mauveine became famous as the world’s first synthetic dye, and Perkin’s work thus started the great dyestuff industry that developed, mainly in Germany, in the later nineteenth century. Many special chemical skills were developed in this industry, and by the end of the nineteenth century these were being applied to the manufacture of new drugs as well as dyes. Perkin’s ambition to develop medicinal substances was, in a long roundabout way, fulfilled, and, after his death, on a vastly wider scale than he is likely to have foreseen. The early history of these new substances, and especially how some came to be recognized as potential medicines, is obscure. German industrial firms worked in great secrecy, and did not reveal how they tested their new products to see if they were medicinal, or harmless, or poisonous. Some new drugs came initially from academic chemists, others from by-products of heavy chemical manufacture pain-relievers (analgesics) and antifever drugs (antipyretics) from coal-tar distillation and, later, from producers of fine chemicals, especially dyestuffs. Practising doctors, either on their own initiative or requested by industry, tried hitherto unknown substances on themselves, on animals, and on patients, sometimes with little more than guesswork about what the substances might do, either of benefit or of harm. Among the most rash experiments were those with nitrous oxide, ether, and chloroform, all of which were found to cause reversible loss of consciousness. Nitrous oxide (laughing gas’), first made by Humphry Davy about 1800, was taken up by showmen at fairgrounds to provide entertainment. Its use as an anaes thetic was inspired by observing that a man who fell and injured himself while Drug Treatment and the Rise of Pharmacology 263 under its influence suffered no pain at the time. Ether was more difficult to inhale, but experiments suggested that it could be more effective, and after some hesita tions both substances were adopted as anaesthetics. So one horror surgery with out anaesthesia was abolished, and new surgical procedures of all kinds became possible (see page 229). Chloroform followed soon afterwards; easiest to give but more hazardous, it was for long a controversial drug. Some thought it was unnatural and wrong to alleviate the suffering inflicted on mankind by God as. However, by the time Queen Victo ria received chloroform administered by John Snow for the birth of Prince Leopold on 7 April 1853, the protests were medical, on the grounds of safety, rather than theological. The editor of the Lancet thundered, Tn no case could it be 9 justifiable to administer chloroform in perfectly ordinary labour’, and went on to the special iniquity of taking risks with the Royal Sovereign. The macologist and immunologist of his day, photographed revolutionary work of Louis Pasteur and Robert Koch and their followers is around 1900, probably shortly described in Chapter 5 (page 184); its significance cannot be overrated. The new after he became director of a knowledge of ‘germs’ started new studies of immunity and of ways in which infec new state research institute in tions could be prevented or overcome. They were, by modern standards, crude and impure materials, containing com plex substances far beyond the chemical knowledge of the time, and not encour aging thought on chemical lines about how they acted. However, such thought was possible, and led the great German medical scien tist Paul Ehrlich to the idea that much simpler substances might act powerfully against microbes without harming the patient.

Typical indications for other nonopioid medication in In general, we never know what the necessary total breakthrough pain would be spasmatic pain or neural dose for pain control will be. By asking the with infiltration of the brachial plexus, first described by patient each time, 5–10 minutes after the opioid appli the American radiologist Henry Pancoast), i.

All drug regimes for cancer patients should to completely take effect before you decide whether fur include a breakthrough pain medication from the start. Breakthrough pain analgesic a rule of the thumb, the patient should be allowed to use titration is considered successful when pain intensity is extra (“demand”) doses of his regular opioid as needed. Again, Can I use the average number of daily demand 10–15% of the total daily dose is calculated, and that ti doses to estimate the true opioid requirement tration dose is offered to the patient every 30 minutes of my patient? If your patient needs five demand doses daily, you Can I use the acute titration dose to estimate should add the cumulative daily demand dose to the the future opioid needs of my patient? Yes, in cancer patients you can pretty well foresee morphine needing morphine demand doses of 10 mg the future opioid demand of your patient. A frequency of fewer than four demand dos morphine for analgesic titration, he or she will have es daily is considered to be “normal,” and therefore the an estimated daily supplemental demand of 120 mg dosing scheme may be maintained. Breakthrough Pain, the Pain Emergency, and Incident Pain 281 What are practical considerations for pain episodes. Usually breakthrough pain has a dif rescue medication will be a normal-release (“im ferent etiology than in cancer pain since there is mediate-release”) opioid analgesic. Alternative routes of administration and lipophil fore, the patient should not receive “free access” ic opioids would appear to be appropriate for pa to demand doses to avoid dose escalations in pain tients with insufficient breakthrough pain control.

Breakthrough pain may result in a number of oth prescribed medications for this kind of activity, er physical, psychological, and social problems. The degree of inter breakthrough pain, but is a bit different, is called ference seems to be related to the characteristics end-of-dose failure. Breakthrough pain is an analgesic that becomes ineffective after a few associated with greater pain-related functional hours, and then pain returns. Generally, breakthrough pain happens fast, and may last anywhere from seconds to Pearls of wisdom minutes to hours. If you to experience breakthrough pain just before or have not offered this option to your patients, al just after taking the regular pain medication. Although it has a delayed onset of ac nerstone for the management of breakthrough tion, and a prolonged duration of effect, studies 282 Gona Ali and Andreas Kopf show that the majority of patients have sufficient [2] Mercadante S, Radbruch L, Caraceni A, Cherny N, Kaasa S, Nauck F, Ripamonti C, De Conno F; Steering Committee of the European Asso breakthrough pain control with this approach.

This occurs because a failing heart will push blood pressure into the lung medicine to increase appetite discount co-amoxiclav 625mg line, which shows up on X-ray as excess fluid in the lung cavity schedule 6 medications order co-amoxiclav online from canada. Therefore medicine 5000 increase cheap co-amoxiclav 625 mg visa, the chest X-ray will do very little to treatment 0 rapid linear progression purchase 625 mg co-amoxiclav diagnose atherosclerosis, before the disease is already known. These electrical waves are Depolarization detectable with wires attached to the chest skin. It will not show the valves, the muscle wall action, or the amount and exact location of occluded arteries from atherosclerosis. It detects mainly the health and blood flow capability of the left ventricle during physical exercise. It takes more than 75 percent occlusion of a major vessel in the heart to show up as an abnormality during stress testing. For example, the vasodilator Dipyridamole is injected and it rapidly increases the local blood flow by causing heart vessel dilation. This vasodilation occurs in healthy arteries, whereas diseased arteries remain narrowed. This creates a “steal” phenomenon in which the blood flow increases to the dilated healthy vessels compared to narrowed diseased arteries. Nuclear Perfusion Imaging I Sestamibi (Cardiolite) scanning uses the radioactive isotope, Technetium-99m (Tc99m), a new nuclear medicine tracer molecule that can be used to assess heart muscle blood flow during stress testing. This molecule passes cell membranes and can be visualized with a gamma camera to “light up” the areas where blood flow is plentiful and where it does not flow due to recent damage (infarction). This has an accuracy equivalent to the Dobutamine Stress Echocardiography for detecting residual infarct-related artery stenosis of greater than 50 percent and multi-vessel 47 disease early after a heart attack. I Thallium-201 scanning uses thallium-201 (Tl-201) injected into the blood stream during stress testing and it “lights up” (much like sestamibi) in the heart muscle using a gamma camera, showing areas lacking blood perfusion (the location of the myocardial infarction). Intima-Media Thickness the tunica intima is where the endothelium of the artery develops thickness of atherosclerotic plaque. Many studies have documented the relation between the carotid intima-media thickness and the presence and severity of atherosclerosis in the coronary arteries of the heart. Therefore, this measurement is valuable for early detection and prevention of atherosclerosis. It focuses on the atherosclerosis rather than the narrowing of the lumen, which is seen on angiography (discussed later). With this video a cardiologist can then assess your heart valves, heart chambers, aorta, and the degree of your heart muscle contraction. The amount of blood that is ejected with each heart beat is measurable, called the ejection fraction. A failing heart has an ejection fraction of less than 25 percent while the normal healthy heart is more than 55 percent. It is also limited in patients with obesity, chronic obstructive pulmonary disease, and chest wall deformities. Before hand you’ll need conscious sedation so you don’t experience much, if any, pain or gagging. These optimizations make heart structures and other features of cardiovascular function easily assessed. Blood appears bright in these pictures in contrast to the muscle due to the rapid flow and imaging properties of blood. Contrast agents can also be given to detect muscle scarring from normal heart muscle. They can also detect coronary artery narrowing during stress, which appears as a transient perfusion defect. Coronary Artery Calcium Scoring Cardiac calcium scoring uses computed tomography to take thin section images of the calcium buildup in the plaque on the walls of coronary arteries. A radiologist interprets the results in regards to the current and future expected risk of having a heart attack. This means that with a score of zero you have no evidence of plaque, and are very unlikely to develop atherosclerosis or experience a heart attack for the next five years. As evidence of plaque increases so does your likelihood of having a heart attack in the next five years. See the scoring system below: Calcium Score Presence of Plaque 0 No evidence of plaque, risk low X 5 yrs more 1-10 Minimal evidence of plaque, symptoms or not 11-100 Mild evidence of plaque 101-400 Moderate evidence of plaque Over 400 Extensive evidence of plaque. The value of using this technique is to rule out coronary artery disease rather than to rule it in. This is because a negative test result means that a patient is very unlikely to have coronary artery disease as the cause for symptoms. Manufacturers have developed a 256-slice scanner and even a 320-slice scanner (Toshiba), which are both upgrades from the standard 64-slice scanners. Coronary Angiography An angiogram is an imaging technique using X-ray pictures that visualize the inner opening (or lumen) of coronary arteries. Angiograms can also be done on arteries of the brain to detect narrowing (stenosis), ballooning (such an aneurysm) or arterio venous malformations. The contrast material is introduced via a catheter that is inserted in the femoral artery (near the groin), passed into the heart and then inserted into a coronary artery under moving X-ray guidance called fluoroscopy. It is seen as a moving picture as the heart beats, and interpretation of the image can be a bit tricky. Atherosclerosis will not be seen directly but is presumed with severe narrowing of an artery. This test gives definitive information and can be enough for a cardiothoracic surgeon to decide to do open heart surgery. Cardiac Markers of Heart Muscle Damage When you go to an emergency room for evaluation of chest pain, there will be several vials of blood taken from you immediately. The following tests will be run: I Troponin: this is a complex protein found in skeletal and cardiac muscle, but not smooth muscle. The level of troponin usually rises within four hours of the onset of anginal chest pain and even before permanent damage is done to the heart. I Myoglobin: Myoglobin is also a molecule that is released from damaged muscle tissue. It is not widely used anymore as a marker of myocardial muscle damage because of the newer, better tests named above. Risk Factors for Stroke Risk factors for stroke are not necessarily the same for cardiac atherosclerosis and heart attack. Treatment with a pharmaceutical drug is the first choice by conventional medicine doctors today. Let me outline the conventional medicinal approach to treating cardiovascular accidents and long-term management of the disease. Medical management of cardiovascular disease in America stems from the misconception that high cholesterol and dietary fats are to blame for the disease. The reality, however, is that patients are not taught how this is effectively done. As a result, the focus nearly always becomes a prescription for a statin drug to lower cholesterol. This may be accompanied by antihypertensive drugs and sometimes antithrombotic drugs. Rarely does a patient get practical hands-on training on nutrient-rich, whole foods and other lifestyle interventions which actually have been proven to reverse atherosclerosis. Do doctors know that nearly half of all heart attack victims have completely normal cholesterol levels? Taking this conventional medicine approach further, when the use of cholesterol-lowering medications does not prevent a heart attack or the chest pains that precede one, called angina, then a surgical intervention is automatically sought. For more than 35 years the standard treatment for significant coronary atherosclerosis has been open heart bypass graft surgery. Recuperation from this highly invasive procedure can take months, and some patients suffer lifetime impairments such as memory loss, chronic inflammation and depression. Another surgical approach is coronary artery angioplasty with or without stenting. Once discovered on an angiogram, these stenotic (narrowed) artery segments can be “ballooned” up mechanically.
There is a loss of protein rich fluids from open wounds symptoms nervous breakdown purchase co-amoxiclav 625mg overnight delivery, which needs to 5 medications that affect heart rate cheap co-amoxiclav american express be replaced symptoms 0f heart attack order 625 mg co-amoxiclav amex. Healing of fractures may involve bed rest medications contraindicated in pregnancy order discount co-amoxiclav, which increases loss of calcium due to lack of movement. Nutritional Care: the losses in injury have to be replaced and needs of healing have to be met. In the first 24-48 hours after injury, the blood volume and electrolyte balance needs to be maintained. Next, the diet must help to resist infection, ensure healing, restore muscular strength and avoid weight loss. Nutrients Needed: (a) Sufficient protein and calories to meet the above-mentioned needs (b) In case of fracture, additional calcium and vit. B complex be increased in proportion to increase in calories and protein (d) Vits. A and C to ensure wound healing and prevent infection Intake of drinks providing high protein and calories between meals ensure adequate nutrient intake and utilization. The mode of feeding oral, tube feeding or parenteral route – depends upon the severity and location of the injury. Surgery It is good to remember that to aid recovery from surgery, nutritional support is necessary. Some illnesses need surgery as a corrective measure, for example, appendicitis, removal of infected part, etc. Prior to surgery, the patient may have lost appetite due to illness or may have had restricted food intake. If there has been vomiting or diarrhea or loss of blood, these may result in losses of sodium, potassium chloride, iron in addition to fluid loss. Nutrition in Stress, Burns and Surgery 347 Nutritional Considerations the most critical factor is protein status of the patient. It is known that the stress of surgery will increase protein losses for several days after surgery. Nutrients needed are: (a) Proteins for wound healing, to ensure resistance to infection and to protect liver from toxicity of anaesthesia. A 30 to 50 per cent increase in calorie and protein intake above maintenance level is needed to help gain weight if the patient is underweight. Postoperative Diet: After a minor surgery, liquids may be tolerated within few hours and return to normal diet is rapid. In other cases, when peristalsis resumes, patients are progressively given ice chips, sips of water, a clear liquid, full liquid, soft and then normal diet. The rate of progression is dependent on the patient’s condition and tolerance of food. If the patient is unable to take food orally or is not able to eat sufficient food, it is necessary to resort to tube feeding or parenteral feeding. If a patient is dehydrated,, it is important to ensure rehydration, before planning surgery. If the surgery is minor, a deficient intake for a few days may not pose a serious problem. But if the person is nutritionally depleted and has to undergo a major surgery, the matter may be serious. Therefore screening persons on admission to identify those at nutritional risk is very important. Specific Surgery Though the basic dietary needs of all surgery patients are similar in each case, attention to some specific aspects helps to ensure comfort of the patient. Teeth: the diet is restricted to liquids (cool), followed by soft foods for multiple tooth extractions Tonsillectomy: After the operation, cold bland food, low-fibre foods are given followed by soft foods, not too hot or cold and then to regular normal diet. Gastrectomy: Removal of part or all of the stomach and vagotomy (cutting of the vagus nerve to relieve pain). In gastric cancer and sometimes for intractable peptic ulcer, part or all of the stomach(gastrectomy) and the vagus nerve (vagotomy) are removed surgically. In absence of vagus nerve, food flow through gastrointestinal tract is increased and diarrhea and steatorrhea are likely to occur. Since tolerance is low, foods are introduced one by one, meals are very small and frequent. The order of introduction of foods is as follows: (1) Cereals, milk, cream soups, fruit, purees, eggs, custards. Dumping Syndrome this is one of the problems faced by some patients after gastrectomy. These patients suffer from nausea, weakness, sweating and faintness soon after eating. The water from blood circulation is tied up by the large amount of carbohydrates present and blood volume is reduced. Avoid very hot or very cold food Eat slowly, chew food well and rest before and after meals Include vitamins and mineral supplements Plan the diet to suit individuals. Low fat milk: 300 ml, if tolerated take ½ 1 hr after meals Dals : Mung, masur, cooked 50 g. Chapati – 1 chapati per meal or 1 slice enriched bread per meal Bread substitutes: rice, boiled or mashed potato or sweet potato, spaghetti, macaroni noodles Cereal: one serving Vegetables: all kinds one serving per meal Fruits: fresh, one serving per meal Fruit juices between meals Fats: butter, cream, oil Nuts: if tolerated Nutrition in Stress, Burns and Surgery 349 In conclusion, surgery, burns, fevers and infections are traumas which lead to increased pace of metabolism in the body. Therefore, the diet must be modified to provide extra fluid, proteins, energy, vitamins and minerals as required in these conditions. When surgery is preplanned or elective, the nutritional status must be improved before surgery. Discuss the various degrees of burns and the nutritional care of the patient with burns. Anorexia nervosa and Bulimia are addictive behaviours related to food intake, while alcoholism is the result of addiction to alcohol and alcoholic drinks. Each case has to be studied and the patient helped to normalcy with patience and perseverance. Though eating disorders have been known since the Middle Ages, the incidence of eating disorders is on the rise in the developed countries. One of the contributing factors is the breakdown of social structure resulting in isolation of individuals. Luckily there is hardly any report of these in India, but one needs to watch and prevent these, as the treatment and rehabilitation of persons suffering from eating disorders is very slow and expensive. The incidence of alcoholism is on the increase in all strata of population in India. It needs to be stemmed as it affects the well being of the whole family adversely All these disorders result in the deterioration of the nutritional status of the person; therefore nutritional rehabilitation of the patient is a very important part of therapy. Girls whose profession demands maintaining ultra slim figures (such as models, Nutrition: Addictive Behaviours in Anorexia Nervosa, Bulimia and Alcoholism 351 dancers, athletes) have long standing histories of eating disorders. So they try to get rid of the food by forced vomiting, fasting, taking diuretics or using laxatives. They keep their binge –purge behaviour a secret and hence it is difficult to identify the disorder until the stress of these episodes results in some visible impact on the system. Causes: Addictive behaviours have multiple causes – emotional, psychological, social and biological, which result in disordered eating. Stress may have a strong role and lack of appropriate coping mechanism is another common factor. Symptoms of Anorexia Nervosa: the anorectic patient is often 20 to 40 per cent below desirable weight for the age and stature and appears to be skin and bones. Other symptoms are lowered body temperature, slower basal metabolism, decreased heart rate (hence easy fatigue, fainting, sleepiness), iron-deficiency anemia, rough dry scaly and cold skin from a poor nutrient intake, low white blood cell count (increasing risk of infection and death), loss of hair, constipation (and laxative abuse), loss of menstrual periods and deterioration of teeth due to frequent vomiting, An anorectic person is psychologically and physically ill and needs help. Treatment of Anorexia Nervosa: the patient is often a victim of isolation and fear. Hence the health team must include a psychologist in addition to a physician, dietitian and other health personnel. They should all work together to restore a sense of balance, purpose and future with the cooperation of the patient. The first step is to help the patient to gain weight, as a psychiatrist cannot counsel a starving person. The third is to ensure that the patient keeps in weekly contact with the dietitian.
