Treatment is supportive: antihistamines are given, often prophylactically, in an attempt to reduce pruritus. Lesions begin in the striae distensae and spread up and around the umbilicus, thighs, and buttocks. In some atypical cases, biopsy should be performed to distinguish the diagnosis from herpes gestationis (8). Urticaria Pigmentosa Urticaria pigmentosa is characterized by persistent, red-brown, maculopapular lesions that urticate when stroked (Darier sign). The diagnosis may be established by their typical appearance, Darier sign, and skin biopsy. Occasionally, it has been noted to complicate other forms of anaphylaxis such as Hymenoptera venom sensitivity, causing very severe reactions with sudden vascular collapse. The remaining forms of urticaria are associated with many diverse etiologies ( Table 13. Diagnosis is established by history and physical examination based on knowledge of the possible causes. Laboratory evaluation is occasionally helpful in establishing a diagnosis and identifying the underlying disease. Treatment is based on the underlying problem, and may include avoidance, antihistamines, and corticosteroid therapy or other forms of antiinflammatory drugs. Clinical Approach History The clinical history is the single most important aspect of evaluating patients with urticaria. The history generally provides important clues to the etiology; therefore, an organized approach is essential. Once the diagnosis of urticaria is established on the basis of history, etiologic mechanisms should be considered. The patient with dermographism usually reports a history of rash after scratching. Frequently, the patient notices itching first, scratches the offending site, and then develops linear wheals. Stroking the skin with a pointed instrument without disrupting the integument confirms the diagnosis. Cholinergic urticaria is usually recognized by its characteristic lesions and relationship to rising body temperature or stress. Familial localized heat urticaria is recognized by its relationship to the local application of heat, and familial cold urticaria by the unusual papular skin lesions and the predominance of a burning sensation instead of pruritus. C3b inactivator deficiency is rare, and can be diagnosed by special complement studies. Thus, after a few moments of discussion with a patient, a physical urticaria or hereditary form usually can be suspected or established. The success of determining an etiology for urticaria is most likely a function of whether it is acute or chronic, because a cause is discovered much more frequently when it is acute. Great patience and effort are necessary, along with repeated queries to detect drug use. Over-the-counter preparations are not regarded as drugs by many patients, and must be specified when questioning the patient. Although theoretically they should not cause angioedema, several case reports have been published (64). Infections documented as causes of urticaria include infectious mononucleosis, viral hepatitis (both B and C), and fungal and parasitic invasions. Chronic infection as a cause of chronic urticaria is a rare event, although chronic hepatitis has been postulated to cause chronic urticaria ( 65). Physical Examination A complete physical examination should be performed on all patients with urticaria. The purpose of the examination is to identify typical urticarial lesions, if present; to establish the presence or absence of dermographism; to identify the characteristic lesions of cholinergic and papular urticaria; to characterize atypical lesions; to determine the presence of jaundice, urticaria pigmentosa (Darier sign), or familial cold urticaria; exclude other cutaneous diseases; exclude evidence of systemic disease; and establish the presence of coexisting diseases. Diagnostic Studies It is difficult to outline an acceptable diagnostic program for all patients with urticaria. Each diagnostic workup must be individualized, depending on the results of the history and physical examination. An algorithm may become a useful adjunct in this often unrewarding diagnostic endeavor ( Fig. Foods Five diagnostic procedures may be considered when food is thought to be a cause of urticaria ( Table 13. Diagnostic studies of food-induced urticaria Skin Tests Routine food skin tests used in evaluating urticaria are of unproven value at best. Because the etiology of chronic urticaria is established in only an additional 5% of patients (38), and only some of these cases will be related to food, the diagnostic yield from skin testing is very low. Important studies of food-induced atopic dermatitis ( 66) have revealed a few selected foods that are most commonly associated with symptoms. Second, for patients in whom a mixed food (combination of ingredients) is thought to be the problem, food tests may isolate the particular item (e. At present, an extensive battery of food tests cannot be recommended on a routine basis, and must be used with clinical discretion. Commercially prepared extracts frequently lack labile proteins responsible for IgE-mediated sensitivity to many fruits and vegetables. If the clinical history is convincing for a food allergy, but skin testing with a commercially prepared extract is negative, testing should be repeated with the fresh food before concluding that food allergen-specific IgE is absent ( 67). Additionally, certain foods have been shown to cross-react with pollen allergens ( 68) or latex allergens (69) to which a patient may be exquisitely sensitive. Although it is considered less sensitive, it may be necessary when a patient has an exquisite sensitivity to a certain food or significant dermographism. Drugs With the exception of penicillins, foreign sera, and recombinant proteins such as insulin, there are no reliable diagnostic tests for predicting or establishing clinical sensitivity to a drug.

One in six patients aged 16 65 years in a large general practice in the United Kingdom consulted at least once because of headache over an observed period of ve years buy cheap femara 2.5mg online, and almost 10% of them were referred to secondary care (25) discount femara online master card. A survey of neurologists found that up to a third of all their patients consulted because of headache more than for any other single complaint (26) discount 2.5 mg femara amex. Far less is known about the public health aspects of headache disorders in developing and resource-poor countries. Indirect nancial costs to society may not be so dominant where labour costs are lower but the consequences to individuals of being unable to work or to care for children may be severe. There is no reason to believe that the burden of headache in its personal elements weighs any less heavily where resources are limited, or where other diseases are also prevalent. For ex- ample, in representative samples of the general populations of the United States and the United Kingdom, only half the people identied with migraine had seen a doctor for headache-related reasons in the last 12 months and only two thirds had been correctly diagnosed (27). Most were solely reliant on over-the-counter medications, without access to prescription drugs. In a separate general-population questionnaire survey in the United Kingdom, two thirds of respondents with migraine were searching for better treatment than their current medication (28). In Japan, aware- ness of migraine and rates of consultation by those with migraine are noticeably lower (29). Over 76 Neurological disorders: public health challenges 80% of Danish tension-type headache sufferers had never consulted a doctor for headache (30). It is highly unlikely that people with headache fare any better in developing countries. The barriers responsible for this lack of care doubtless vary throughout the world, but they may be classied as clinical, social, or political and economic. Clinical barriers Lack of knowledge among health-care providers is the principal clinical barrier to effective head- ache management. This problem begins in medical schools where there is limited teaching on the subject, a consequence of the low priority accorded to it. It is likely to be even more pronounced in countries with fewer resources and, as a result, more limited access generally to doctors and effective treatments. Social barriers Poor awareness of headache extends similarly to the general public. Headache disorders are not perceived by the public as serious since they are mostly episodic, do not cause death and are not contagious. In fact, headaches are often trivialized as normal, a minor annoyance or an excuse to avoid responsibility. These important social barriers inhibit people who might otherwise seek help from doctors, despite what may be high levels of pain and disability. Surprisingly, poor awareness of headache disorders exists among people who are directly affected by them. A Japanese study found, for example, that many patients were unaware that their headaches were migraine, or that this was a specic illness requiring medical care (31). The low consultation rates in developed countries may indicate that many headache sufferers are unaware that effective treatments exist. Political and economic barriers Many governments, seeking to constrain health-care costs, do not acknowledge the substantial burden of headache on society. They fail to recognize that the direct costs of treating headache are small in comparison with the huge indirect cost savings that might be made (for example by reduc- ing lost working days) if resources were allocated to treat headache disorders appropriately. Therefore the key to successful health care for headache is education (31), which rst should create awareness that headache disorders are a medical problem requiring treatment. Education of health-care providers should encompass both the elements of good management (see Box 3. Diagnosis Committing sufcient time to taking a systematic history of a patient presenting with headache is the key to getting the diagnosis right. The history-taking must highlight or elicit description of the characteristic features of the important headache disorders described above. The correct diagnosis is not always evident initially, especially when more than one headache disorder is present, but the history should awaken suspicion of the important secondary headaches. Once it is established that there is no serious secondary headache, a diary kept for a few weeks to record neurological disorders: a public health approach 77 the pattern of attacks, symptoms and medication use will usually clarify the diagnosis. Physical examination rarely reveals unexpected signs after an adequately taken history, but should include blood pressure measurement and a brief but comprehensive neurological examination including the optic fundi; more is not required unless the history is suggestive. Examination of the head and neck may nd muscle tenderness, limited range of movement or crepitation, which suggest a need for physical forms of treatment but do not necessarily elucidate headache causation. Investigations, including neuroimaging, rarely contribute to the diagnosis of headache when the history and examination have not suggested an underlying cause. Realistic objectives There are few patients troubled by headache whose lives cannot be improved by the right medical intervention with the objective of minimizing impairment of life and lifestyle (32). Cure is rarely a realistic aim in primary headache disorders, but people disabled by headache should not have unduly low expectations of what is achievable through optimum management. Medication-overuse headache and other secondary headaches are, at least in theory, resolved through treatment of the underlying cause. Predisposing and trigger factors Migraine, in particular, is said to be subject to certain physiological and external environmental factors. While predisposing factors increase susceptibility to attacks, trigger factors may initiate them. Trigger factors are important and their inuence is real in some patients, but generally less so than is commonly supposed. Dietary triggers are rarely the cause of attacks: lack of food is a more prominent trigger. Many attacks have no obvious trigger and, again, those that are identied are not always avoidable. Diaries may be useful in detecting triggers but the process is complicated as triggers appear to be cumulative, jointly overowing the threshold above which attacks are initiated. Too much effort in seeking triggers causes introspection and can be counter-productive. Enforced lifestyle change to avoid triggers can itself adversely affect quality of life. In tension-type headache, stress may be obvious and likely to be etiologically implicated.

Most of these genes are new to medical science, and working out the functions they control is the key to designing new drugs, and to detecting illness early, or preventing illness. Virtually all human genes have mouse equivalents, and studying how the genes work in mice is often the most effective way of discovering the genes role in human health and disease. Having a living model for a human disease is a powerful tool in understanding how to treat or prevent the illness. Mice have been produced which are susceptible to some human cancers, and more recently the creation of a cystic fibrosis mouse has allowed invaluable work into this fatal illness. Changing single genes can allow the disease 2624 processes to be switched off one at a time, to develop a clearer picture of the disease, and how each aspect of the disease might be tackled. Some people have argued that creating transgenic animals is unnatural or represents a new form of cruelty to animals. The effects of genetic modification are closely monitored,against the same standards that apply in every other area of research. Other concerns have been raised that the process of creating transgenic strains is wasteful,as much breeding has to be done to produce relatively small numbers of altered animals. However, care is taken to try to produce only the numbers of animals that are needed. As better ways of introducing new genes are developed,the process will become more precise. This method is particularly valuable if the genetic variation affects the animals health: reducing the stocks of these mice is a priority. Genetic modification is an effective research method that can give clear answers more quickly than older research techniques using animals. This does mean that this area of medical research is the only one where the use of animals is increasing. But this is a necessary development because of the unique opportunities to understand the roles genes play in human illness. Most of these procedures were in applied medical research or basic biological research,but the figures also include veterinary research (7%). About half a million of the procedures are safety tests required by law on new medicines, veterinary products, and other new products. Many research procedures do not involve significant animal suffering:some are simple tests such as taking blood for analysis. Around 94% of the licences allow only procedures graded as mild or moderate:less than 2% are substantial. Nationally, mice, rats and other rodents were used in the majority of procedures 85% of the total. The rest involved mice or other animals with either a natural or a man-made genetic variation. But animal studies rarely involve surgery, and animals are not anaesthetised for experiments involving injections, blood samples, and other minor procedures. We support roughly the same amount of research again through grants to universities and hospitals. The numbers of mouse procedures are higher, because studies on mice are one of the main ways of understanding the genetics of human disease. In counting procedures, we include every mouse bred simply to keep special genetic strains going where there is any risk that the genetic variation in the mice might cause illness or disability as well as mice used in experiments. For this reason the numbers of mice linked to genetic research are higher than in other areas of research. Alongside these statutory controls, researchers and scientists are striving to promote animal welfare through a culture of care. The aims are to cut the numbers of animals needed in tests, and where animals must be used, to ensure that distress is kept to a minimum. Legal controls on the use of animals in experiments have existed in Great Britain since 1876.

A primary focus on directed living donation femara 2.5mg overnight delivery, at the expense of developing efficient communal donation systems buy femara visa, might risk losing or diminishing this sense of communal concern 2.5 mg femara for sale. Diverting attention away from deceased donation would also serve to neglect forms of bodily material (for example hearts) that may only be donated after death. Yet in both cases, the potential availability of bodily material (kidneys for transplantation or eggs for fertility treatment) depends on individuals in other countries exchanging those materials for money, often in the face of significant economic hardship. However, in the case of organs, the nature of the good to be achieved the saving and enhancing of life provides an impetus to achieve a communitarian solution to the problem of organ scarcity (a system of deceased donation), allowing people the opportunity to contribute to the survival of those who remain strangers to them. Such a consideration provides a powerful reason to support and encourage an efficient system of deceased donation that will both reduce the temptation to travel abroad for treatment and ensure a more equitable approach to the allocation of available organs. We distinguish between altruist-focused interventions (that act to remove disincentives from, or to provide a spur to, those already inclined to donate); and non-altruist- focused interventions (where the reward offered to the potential donor is intended alone to be sufficient to prompt action). We distinguish authorisation/willingness to donate from consent in these circumstances, on the grounds of the potentially different informational requirements involved. This is true both of trust in individual professionals, for example that they will exercise a duty of care towards donors and respect their confidentiality; and of trust in systems, that they are the subject of good and transparent governance. In such a climate of change, it is particularly important that policy makers should remain alert to the importance and value of the donation of bodily material, and should act to ensure that valuable systems currently in place are not inadvertently lost. Indeed, we note the interconnected nature of the two perspectives: for example if an organisation is well respected and trusted (a result of organisational ethos and action), then people may be more likely to make their own individual decisions to donate 562 (individual action). We reiterate here, as we have done elsewhere in this report, that we do not assume that an approach that is judged to be ethical and effective in one field will automatically be so in another. We note here that there are other areas in particular surrogacy arrangements and the donation of whole bodies to medical schools for education and research where we have not felt well-placed to make specific recommendations. Nevertheless, we hope that our ethical analysis will also be helpful to those working in these areas. However, it is still constructive to distinguish between those policy initiatives that seek primarily to change how individuals behave, and those targeted at the behaviour and functions of organisations. We therefore recommend that, where a health need is not being met by altruist-focused interventions, the following factors should be closely scrutinised, in order to ascertain whether offering a form of non-altruist-focused intervention might or might not be harmful: The welfare of the donor; The welfare of other closely concerned individuals; The potential threat to the common good; The professional responsibilities of the health professionals involved; and The strength of the evidence on all these factors. People may be influenced by many considerations, and there is much debate as to their likely responsiveness both to particular forms of encouragement and to particular ways in which their consent may be sought. This certainly does not mean, however, that we consider that they become redundant. Rather, we emphasise that the way in which they are being used in particular circumstances should be made explicit and, where necessary, justified. Such an idea of altruism is closely linked with solidarity: both may be seen as aspirational, setting a standard for the kind of society that one would wish to live in, particularly in the context of the way that society provides health care as a basic good. It makes a valuable contribution to the vocabulary with which the common good is conceptualised in this context, and is particularly powerful in the way that it joins up with individual motivation. In this chapter we apply our ethical framework with this in mind, considering also the issue of evidence. Twenty papers in total were identified: five on blood donation, nine on organ donation, two on tissue donation and four on egg donation (including egg-sharing). One prospective study also found that belief in the personal benefits to be gained from donating (that is, that donation would make 565 donors feel good about themselves) was the best predictor of future donation behaviour. Reasons given by non-donors were more wide-ranging: in one study 42 per cent of non-donors cited medical contraindications, with other factors being fear of needles, a simple lack of interest 563 See Appendix 1 for details of the evidence review and the criteria for inclusion. Because of the very large number of papers originally identified, the part of the review concerned with the donation of bodily material focused specifically on potentially modifiable factors relating to motivators and deterrents to donation rather than the personality characteristics of donors and non-donors. The role of fear and anxiety was raised in a number of studies: such fears include anxiety about the process of blood donation itself (for example fear of needles or of fainting), fear of the unknown, and concerns about the risk of negative 567 outcomes, such as contracting a blood-borne disease. In another, both donors and non- donors identified the same top three factors (a major disaster, more frequent mobile units and 568 being specifically invited) as being most likely to encourage them to donate. Medical mistrust was expressed both through the anxiety that a potential organ donor would not receive appropriate medical care (for example by less effort being put into resuscitation) and through concern that organs might be taken for other purposes than 573 transplantation, or additional organs taken without consent. The first study is particularly striking in that, of over 3,000 patients asked to consent to the use of their tissue removed during surgery for commercial research, just 1. Reasons for refusing included mistrust of how the material would be used, and concern that their own care might be compromised (for example by not enough material being retained for their own diagnosis). The study did, however, suggest that empathy with those needing donor eggs in order to have the chance to conceive was also experienced as a motivating 576 factor. Other studies of egg sharers not included within the review similarly noted that those entering in egg-sharing arrangements describe their motivations as both self-interested and 577 altruistic. The three remaining studies explored factors associated with the intention of donating eggs outside the context of egg sharing, both for another persons treatment and for research: identified factors include positive attitudes towards the value of egg donation and the importance of parenthood, a sense of control over the decision-making process, and support 578 from others. A systematic review of English-language peer-reviewed studies on egg donation, published in 2009, noted 12 studies that included volunteer egg donors: motivations cited in these studies included both general altruistic motives for donation and personal experiences of 579 infertility (for example through family and friends). We also flag here the well-known difficulty of interpreting what is told to the researcher: that ones description of ones own motivation in any particular case may only ever 576 Rapport F (2003) Exploring the beliefs and experiences of potential egg share donors Journal of Advanced Nursing 43: 28- 42.

Keeping these qualifications in mind, we would suggest that a number of points can, tentatively, be made from the research reviewed above. It suggests that, if approached appropriately, the vast majority of patients do not have any objection either to permitting research use of tissue excised during surgery, or to such uses being commercial. We return to this issue when we consider possible changes to consent defaults later in this chapter (see paragraph 6. Such a consideration highlights the serious difficulties involved in schemes that aim to increase donation by giving priority in allocation to those willing to give, however attractive and reasonable such schemes may seem at first sight (see paragraphs 2. This leads us on to a consideration of the potential role of such incentives in the donation of bodily material itself. Only studies that explicitly compared two groups (non-incentivised and incentivised) were included. In total, 22 studies were identified that considered the effect of an incentive on the quality of the donated material, and four that considered the effect of an incentive on the quantity (two dealing with both).
