The major compo nents of iron need for children are: basal iron losses; increase in hemoglobin mass; increase in tissue (nonstorage iron); and menstrual iron losses in adolescent girls (aged 14 through 18 years) fungus on neck purchase nizoral 200 mg without a prescription. In this model, no provision was made for the development of iron stores after early childhood. It is accepted that all recognized func tions of iron are met before significant storage occurs and that stores are a reserve against possible future shortfalls in intake rather than a necessary functional compartment of body iron. Because most individuals in this age group in the United States and Canada are believed to consume iron at levels above their own require ment, it can be assumed that most will accumulate some stores. The associated physiological processes that have major impacts on iron requirements are the growth spurt in both sexes, menarche in girls, and the major increase in hemoglobin concentrations in boys. Because the growth spurt and menarche are linked to physiological age, the secular age at which these events occur varies among indi viduals. Since the growth spurt and menarche can be detected in the individual, provision is made for adjustments of requirement estimates when counseling specific individuals. Estimation of the variability of requirements in this age range is complicated because of the physiological changes that occur. In this report, median requirements for absorbed iron are estimated for each year of age, but the variability of requirement and the requirement for absorbed iron at the ninety seven and onehalf percentile are estimated at the midpoint for children 9 through 13 years (11 years) and adolescents 14 through 18 years (16 years). Although requirement estimates have been developed for individual ages, these should be interpreted with care. Unsmoothed data have been used and yearbyyear fluctuations may not be meaningful. In addition to achieved size, it is necessary to estimate growth rates (weight velocities). After fitting linear regressions to median weights for segments of the age range, the regression slopes were taken as estimates of median weight velocities for the age interval. Observa tions in adult men were extrapolated to adolescents on the basis of 14 mg/kg median weight and the losses for each age group are shown in Table 910. Estimation of the net iron utilization for increasing hemoglobin mass necessitates estimation of the rate of increase in blood volume and estimation of the rate of change in hemoglobin concentration. Blood volume is taken as approximate ly 75 mL/kg in boys and 66 mL/kg in girls (Hawkins, 1964). The rate of change in hemoglobin concentration has been directly estimated as the coefficients of the linear regression models applied to hemoglobin versus age for Nutrition Canada data by Beaton and coworkers (1989). The rate of change in hemoglobin concentration and the average hemoglobin concentrations for boys and girls are shown in Table 911. This is because the summation of the median of nonnormal distri butions (above) do not yield the median of simulation models that represent normal ized data. In working with individuals, menstrual status can be ascertained and an adjustment can be made. Boys ([Weight (kg) fi increase in hemoglobin concentration (kg/L/year)] + [Weight gain (kg/year) fi hemoglobin concentration (g/L)]) fi blood volume (0. Girls ([Weight (kg) fi increase in hemoglobin concentration (kg/L/year)] + [Weight gain (kg/year) fi hemoglobin concentration (g/L)]) fi blood volume (0. For example, the medium daily need for increased hemoglobin mass for a 16yearold girl would be ([55. Nonstorage tissue iron concentration (myoglobin and enzymes) (Table 910) can be calculated when the average weight gain for boys and girls and the iron content in muscle tissue are known. The median need for absorbed iron associated with increase in weight in both sexes is Tissue iron = Weight gain (kg/year) fi nonstorage tissue iron (0. It is not a component of requirement though it can be expected to occur when intake exceeds actual requirement. Iron losses in the menses can be calculated when the average blood loss, the average hemoglobin concentration, and concentration of iron in hemoglobin (3. It was deemed appropriate to use the blood losses reported by Hallberg and coworkers (1966a, 1966b) with additional information from Hallberg and RossanderHulthen (1991) and, more specifically, to use the blood loss estimates for 15yearold girls. Several important features of these and other data related to men strual blood loss were recognized in developing models to predict requirements: Menstrual losses are highly variable among women and the dis tribution of losses in the population shows major skewing, with some women having losses in excess of three times the median value. Hallberg and coworkers (1966b) found very little difference in blood loss with age. Losses were lower in the 15yearold group, but incomplete collection might have been a factor. Cole and coworkers (1971) reported a small effect of age that was attributed to two covariates, parity and infant birth weight. Bleeding is significantly increased by the use of certain intrauterine devices and significantly decreased in individuals taking oral contra ceptives. This data set was selected for the following reasons: It is representative of the other survey data quoted above and can be considered generalizable to women living in countries other than that of the study, including the United States and Canada. Blood losses per menstrual cycle were converted into estimated daily iron losses averaged over the whole menstrual cycle. The fol lowing assumptions were made: Blood loss does not change with mild anemia and is therefore independent of hemoglobin concentration. Comparison of the observed and mod eled values (Table 912) provides a way of visualizing the adequacy of the fit of the model. A lognormal distribution was fitted to the reported percentiles of the blood loss distribution (natural log of blood loss = 3. Although these high menstrual losses were found in apparently healthy women, it would be diffi cult to exclude unidentified hemostatic disorders (Edlund et al. The investigators considered all the subjects they studied to be free of any condition that might affect menstruation. Regression estimates of hemoglobin concentration and rates of change in hemoglobin concentration by age and gender have been derived by Beaton and coworkers (1989). Estimated hemoglobin concentration for females 14 to 20 years of age was 131 g/L + 0. The above data were used to compute median menstrual iron loss as follows: (Blood loss [27. After summing the components for each individual in the simulated pop ulation, the estimated percentiles of distribution were tabulated and are shown in Appendix Tables I3 and I4. While Table 910 shows an estimate of median requirement, it is a simple summation and does not reflect the distributions. Basal or obligatory losses were derived from Green and coworkers (1968) with the assumption of proportionality to body surface area. Various transformations were then tested; a square root transformation approximated normality. The relative variability of surface area in this proxy data set was taken as an estimate of variability of basal iron loss. Estimating iron associated with change in hemoglobin mass re quires consideration of rate of increase in blood volume and in hemoglobin concentration. For the purpose of modeling, blood volume as a proportion of body weight and rate of hemoglobin change as a function of age were taken as constants. The variability of iron need was attributed to variation in weight and weight velocity. Estimates of weight velocity at ages 11 and 16 years were based on the analyses of longitudinal data reported by Tanner and coworkers (1966) (Table 99).

Original Research Article Diagnostic utility of bone marrow aspiration in pancytopenia 1 2* Vijaya Nirmala B, Ramana P. Abstract Back ground: Pancytopenia is a common haematological finding in clinical practice. It is a striking feature of many serious and lifethreatening illnesses, ranging from simple druginduced bone marrow hypoplasia, megaloblastic anaemia to fatal bone marrow aplasias and leukaemia. The severity of Pancytopenia and the underlying pathology determine the management and prognosis. Thus, identification of the correct cause will help in implementing appropriate therapy. Pancytopenia is a common haematological finding for which bone marrow aspiration is conducted. Aim: To study the bone marrow aspiration smears in Pancytopenia cases and correlating with peripheral smear and clinical findings to arrive at a diagnosis. Materials and methods: this was a study conducted at Department of Pathology, Gandhi Medical College on 148 cases of Pancytopenia presenting over a period of 2 years. Clinical findings, complete blood counts and peripheral smear findings were recorded and Bone marrow aspiration was done. Results: Out of 148 cases of Pancytopenia 67 cases were males and 81 were females. Megaloblastic Anaemia was found to be the most common cause of Pancytopenia followed by hypoplastic marrow. Conclusion: A thorough Evaluation of bone marrow smears can diagnose underlying pathology in most cases of Pancytopenia. Correlating bone marrow features with clinical and haematological findings aid in diagnosing and management of most cases of Pancytopenia.

An action plan are now ready to learn from doing by developing and implementing should not be viewed as a static document. An action plan describes the specifc steps necessary to meet clearly > How you will assess impacts and outcomes. The initiative planning model described at the end of Section 2 (page 53) provides an outline of the components to include in your action plan. Some of these groups or individuals may be part of your existing partnership, whereas others may be invited because they bring a different perspective or experience. After the planning group has been organized it should meet to determine what action steps are necessary. Once these steps have been developed, assign specifc roles and responsibilities to partners and devise a timeline for all action steps. This determination should be made following a group discussion about who should be responsible for what. The group will need to estimate the time needed for each action step and be sure the times are reasonable for everyone involved. The group will need to identify existing resources frst and then determine whether additional resources will be required. Anticipating challenges Once an action plan has been formulated that meets the criteria above, revise Any partnership working to change conditions within a community should it as needed to maximize your chances for success.

Take time to appreciate what has been and is not necessarily a bad thing if handled well. Confict due to power accomplished and to publicly recognize what people have contributed. Although recognition of such imbalances can create tension and discomfort among partnership members, you can use the tension to your advantage by discussing differences in access to social resources among various groups in your community and the potential implications of these differences. If this is a problem, review each principle and determine challenges to adherence. Post the principles at each partnership meeting and review and revise them as needed. Partners may You can help prevent conficts from damaging the partnership by encouraging become impatient or dissatisfed with the direction of the partnership or members to openly discuss actual or potential conficts, modifying the action the time it takes to make decisions and implement actions. For example, plan if necessary and feasible and ensuring that community members help some people fnd the community development approach frustrating due defne the actions most appropriate for their communities. You may need to remind members better understand and respect the roles their partners have outside them that the focus on process is an effort to promote participation of all of the partnership. For example, agencies or organizations that receive public funding achievable action steps in your action plan should help reduce the may be prohibited from participating in certain policy activities. However, even frustration of partners eager for immediate change and give them a those agencies can play some role in policy change (see page 70). Working sense of accomplishment that will help them stay in the partnership for collaboratively to determine the most appropriate role for each partner will the long haul.

Although each initiative is unique, the there are several questions your partners may want to consider. Information your partners collect on this initiative can provide information for others engaged in similar work, and your partners can share this information with people and organizations in the community who are interested in your progress. All partners should be actively involved in tracking your progress, 69, 96, 97 which should include steps to defne the questions to address, collect and track information, assess and interpret fndings, and report fndings to others. One of the frst things to consider is how to evaluate the processes used to develop and carry out your initiative. To assess your partnership, your partners should discuss what to document, with whom the information should be shared, and how it is to be used. For example, your partners might want to document satisfaction with what has been accomplished to gauge continued interest in participating in the project. It might also be useful to document the extent to which partners feel they have been involved in decision making and their comfort with confict management strategies. Partners may also choose to review the minutes from meetings to ensure that activities are being carried out as agreed upon by the group. The accomplishments and challenges documented will help guide future partnership initiatives. In addition, many resources exist to guide the development and implementation of partnership evaluation plans.

Discussions on biologic plausibility are presented after new epidemiologic evidence and before the synthesis of all the evi dence antifungal cream prescription cheap 200mg nizoral. The degree of biologic plausibility itself infuences whether the committee perceives positive fndings to be indicative of a pattern or the product of statistical fuctuations. Studies that use isolated cells in culture also can elucidate how a chemical alters cellular processes. The objectives of those toxi cology studies are to determine what toxic effects are observed at different ex posure levels and to identify the mechanisms by which the effects are produced. To be considered an acceptable surrogate for the study of a human disease, an animal model must reproduce, with some degree of fdelity, the manifesta tions of the disease in humans. However, a given effect of an exposure in an animal species does not necessarily establish its occurrence in humans, nor does the apparent absence of a particular effect in animals mean that the effect could not occur in humans. In addition to possible species differences, many factors affect the ability to extrapolate results from animal studies to health effects in humans. The following, which are elaborated on in Chapter 4, are among the most important: Physiologic differences. Humans are ex posed to xenobiotics from multiple sources throughout their lifetimes. Most xenobiotic exposures occur in complex mix tures; the makeup of these mixtures can heavily infuence the ultimate toxic effects. In addition to the dietary modulation of responses to other exposures of both humans and animals, including dietary supplements in humans, prescription and overthecounter pharmaceuticals, and other factors (such as cigarette smoking and ambient pollution) may have effects. For example, the current committee included chronic skin conditions, which had not specifcally been addressed by prior committees. Comments received at public hearings and in written submissions from veterans and other interested persons have been valuable in identifying issues to be pursued to greater depth in the scientifc literature. In aggregate, the health outcomes that the committee has focused on include cancers of all types, cardiovascular and metabolic outcomes such as diabetes, immune system disorders, and neurologic disorders. Other chronic health out comes have also been considered, including respiratory disorders, gastrointestinal disorders, endocrine disorders, and bone conditions. Although for most health outcomes the primary focus of the evaluation was on adverse outcomes in the veterans themselves, to examine potential effects, the children of Vietnam veterans and also later generations were included in the evaluation of the literature. Because any effect of the herbicides or contaminants in individuals or groups of veterans is evaluated in terms of disease or medical outcome, the committee paid particular attention to disease diagnosis and classifcation as it assembled pertinent data from various investigations related to a particular outcome in prepa ration for integrating the information. For example, a patient may report having been treated for stomach cancer when the correct diagnosis was gastric adenocarcinoma, gastric lymphoma, or peritoneal cancer. How ever, such grouping into broader outcome categories can be problematic (and the same is true when categorizing potential exposure). Therefore, if a report indicated that a cohort has an increased incidence of digestive system cancers, then it would be unclear whether the association was attributable to excess cases of any single organ or type or to some combina tion thereof. This can also be an issue in mortal ity studies when more than the primary cause of death is used. Determining whether an estimated association between an exposure and an outcome represents a real relationship requires careful scrutiny because there can be more than one explanation for an estimate. There are several types of biases, and each type may affect the estimate differently. Another type of bias that may potentially affect studies of Vietnam veterans is detection bias, in which veterans who are encouraged to and who choose to participate in screening programs or registries, such as the Agent Orange Registry (discussed in Chapter 5) may have additional tests or followup exams that could potentially detect disease or a con dition earlier or because more thorough assessments were conducted. Incidence is the num ber of new cases of illness during a given period of tim e in a specified population divided by the total population. Detection bias may lead to an overestimate or underestimate of the true effect size. Effect modifca tion occurs when an exposure has a different effect among different subgroups or strata. In its examination of these epidemiologic studies, the committee looked for evidence of health effects that are associated with the specifc compounds in the herbicides used in Vietnam and sought consideration of and adjustment for other possibly confounding exposures. The strength of questionnairebased information as evidence of exposure is enhanced to the extent that the information can be corroborated or validated by other sources. Categories of Association As was done in previous volumes, the current committee used four categories of association to rate health outcomes based on the strength of the scientifc evi dence. The coherence of the full body of epidemiologic information, including biologic plausibility, is considered when the committee reaches a judgment about association for a given outcome. As was the case with the past three update committees, this committee did not use the Bradford Hill criteria for causality (Hill, 1965) as a checklist for its strengthofassociation assessments. The committee discussed the evidence and reached consensus on the categorization of the evidence for each health outcome, which appears in the Conclusion section for each health outcome. Suffcient Evidence of an Association For effects in this category, a positive association between herbicides and the outcome must be observed in studies in which chance, bias, and confounding can be ruled out with reasonable confdence. Experimental data supporting biologic plausibility strengthen the evidence of an association but are not a prerequisite and are not enough to establish an association without corresponding epidemio logic fndings. Typically, at least one highquality study indicates a positive association, but the results of other studies could be inconsistent. Even for a single exposure, a spectrum of results would be expected, depending on the power of the studies, inherent biological relationships, and other study design factors. Such studies might have failed to control for confounding factors or might have had inadequate assessment of exposure. For each substance, this chapter includes a review of its toxicokinetic properties, a brief summary of the toxic outcomes investigated in animal experiments, and a discussion of underlying mechanisms of action as illuminated by in vitro studies. If inhaled, the substance enters the bloodstream through the alveoli in the lungs. For example, the hydrophobicity of a chemical and its solubility in fat infuence how much of that chemical is absorbed. As the chemical is moved through the body, it may enter a target tissue where it may have its ultimate toxic effect, or it may enter into tissues that sequester it. As a chemical is distributed in the organism, it will also begin to undergo metabolism. Biotransformation or metabolism is the process by which a foreign substance is chemically modifed when it enters an organism. As metabolism occurs, the parent chemical is converted into new chemicals called metabolites, which are often more watersoluble (polar) and thus more readily excreted. M etabolism may, however, generate a chemical that is more potent or more toxic than the parent compound. Excretion is the removal of substances or their metabolites from the body, most commonly in urine or feces. This is different from elimination, which refers to the disappearance of the parent molecule from the bloodstream. The rate of excretion of a chemical from the body is often limited by the rate of metabolism of the parent chemical into more watersoluble, readily excreted metabolites. Incomplete excretion results in the accumulation of foreign substances that can adversely affect biologic functions. Shorter halflives were observed in humans during the frst months after exposure or in severely contaminated persons, which is consis tent with the nonlinear elimination predicted by physiologically based pharmaco kinetic models. Collectively, the routes and rates of absorption, distribution, biotransforma tion or metabolism, and excretion of a toxic substance make up the toxicokinetics (or the pharmacokinetics for chemicals used as pharmaceutical agents) of the substance. The basic principles involved in toxico kinetics are similar from chemical to chemical, but the precise way in which principles are applied will depend on the structure and other inherent properties of the particular chemical under consideration. The degree to which different toxicokinetic processes infuence the toxic potential of a chemical depends on the metabolic pathways, which often differ among species.

Such anatomic abnormalities as hiatal hernia fungus gnats h2o2 purchase nizoral us, Schatzki rings, and diverticula (Zenker or epi phrenic) can be seen as well. In patients with esophageal reflux, the radiologist may iden tify reflux of the barium from the stomach back into the esopha gus. If perforations or rupture of the esophagus are suspected, it is best not to use barium; rather, watersoluble xray contrast should be used. If swallowing function is to be evaluated and there is a concern for the potential of aspiration during the test, barium should be used instead of Gastrografin, which can cause a chemical pneumonitis. Contraindications Patients with evidence of bowel obstruction Barium may create a stonelike impaction. Usually, when perforation is suspected, diatrizoate (Gastrografin), a watersoluble contrast medium, is used. B Instruct the patient not to take anything by mouth for at least 8 hours before testing. Usually this is barium sulfate in a milkshake like substance; however, if a perforated viscus is possible, Gastrografin is used. As the patient drinks the contrast through a straw, the xray table is tilted to the nearerect position. The patient is asked to roll into various positions so that the entire esophagus can be adequately visualized. With fluoroscopy, the radiologist follows the barium col umn through the entire esophagus. Initially stools are white but should return to a normal color with complete evacuation. The test is used to detect and monitor the treat ment and clinical course of multiple myeloma and other similar diseases. Bence Jones proteins are monoclonal lightchain portions of immunoglobulins found in 75% of patients with multiple myeloma. They also may be associated with tumor metastases to the bone, chronic lymphocytic leukemias, lym phoma, macroglobulinemia, and amyloidosis. Immunoglobulin light chains are usually cleared from the blood through the renal glomeruli and are reabsorbed in the proximal tubules; thus, urine lightchain concentrations are very low or undetectable. The production of large amounts of mono clonal light chains, however, can overwhelm this reabsorption mechanism. Because the Bence Jones protein is rapidly cleared from the blood by the kidneys, it may be very difficult to detect in the blood; therefore, urine is used for this study. Routine urine testing for proteins using reagent strips often does not reflect the type or amount of proteins in the urine. In fact, the strip may show a completely negative result despite large amounts of Bence Jones globulins in the urine. Proteins in the urine are best identified by protein electrophoresis of the urine. With this method, the proteins are separated based on size and electrical charge in an electric field when the urine specimen is applied to a gel plate. After the various proteins are separated, antisera to specific proteins can be added to the gel and specific precipitin arcs can be identified and quantified (immunofixa tion). Monitoring the urine Mspike (a spike on electrophoresis indicating multiple myeloma) is especially useful in patients with lightchain multiple myeloma in whom the serum Mspike may be very small or absent, but in whom the urine Mspike is large. Instruct the patient to collect an early morning specimen of at least 50 mL of uncontaminated urine in a container. In the liver, indirect bilirubin is conjugated with a glucuronide, result ing in conjugated (direct) bilirubin. The conjugated bilirubin is then excreted from the liver cells and into the intrahepatic cana liculi, which eventually lead to the hepatic ducts, the common bile duct, and the bowel. Jaundice is the discoloration of body tissues caused by abnormally high blood levels of bilirubin. This yellow discol oration is recognized when the total serum bilirubin exceeds 2. This results in a high circulating blood level of uncon jugated bilirubin, which can pass through the bloodbrain bar rier and be deposited in the brain cells of the newborn. The spleen, liver, kidneys, and gastrointestinal tract contribute to this process. When the jaundice is recognized either clinically or chemi cally, it is important (for therapy) to differentiate whether it is predominantly caused by unconjugated or conjugated bilirubin. These are separated out when fractionation or differentiation of the total bilirubin to its direct and indirect parts is requested from the lab oratory. In patients with jaundice, when more than 50% of the bilirubin is conjugated, it is considered a conju gated hyperbilirubinemia from gallstones, tumors, inflammation, scarring, or obstruction of the extrahepatic ducts. Unconjugated hyperbilirubinemia exists when less than 15% to 20% of the total bilirubin is conjugated. Drugs that may cause increased levels of total bilirubin include allopurinol, anabolic steroids, antibiotics, antimalarials, ascor bic acid, azathioprine, chlorpropamide, cholinergics, codeine, dextran, diuretics, epinephrine, meperidine, methotrexate, methyldopa, monoamine oxidase inhibitors, morphine, nico tinic acid (large doses), oral contraceptives, phenothiazines, quinidine, rifampin, salicylates, steroids, sulfonamides, the ophylline, and vitamin A. Drugs that may cause decreased levels of total bilirubin include barbiturates, caffeine, penicillin, and salicylates (large doses). Prolonged expo sure (longer than 1 hour) to sunlight or artificial light can reduce bilirubin content. In this test, those agents to which humans are most likely to be exposed, either in war or a civilian terrorist attack, are discussed. Botulism infection the botulinum toxin produced by Clostridium botulinum causes this disease. The organism also can be inhaled by handling these items or by open wound contamination of soil that contains C. Blurred vision, dysphagia, and muscle weakness progress ing to flaccid paralysis are symptoms of the disease. Symptoms begin 6 to 12 hours after ingestion of the contaminated food or approximately 1 week after wound contamination. The test used to diagnose this disease involves the identifica tion of the toxin in the blood, stool, or vomitus of the affected individual. However, this antitoxin presents a risk of serum sickness in nearly one fourth of the patients who receive it. Anthrax Anthrax is caused by Bacillus anthracis, which is a sporeforming grampositive rod. Pulmonary anthrax results from inhalation of spores or tissues from infected animals. Cutaneous anthrax occurs after contact with contaminated meat, wool, hides, or leather from infected animals. Symptoms include fever, malaise, and fatigue progressing to cutaneous lesions, or pulmonary failure. Appropriate specimens for culture would be stool, blood, sputum, and the cutaneous vesicle. Treatment for this disease is B early institution of antibiotics and supportive care. Hemorrhagic fever (yellow fever) this disease complex has many causative viruses, including arenavirus, bunyavirus (including hantavirus), filovirus (includ ing Ebola), and flavivirus. Symptoms include fever, thrombocy topenia, shock, multiorgan failure, lung edema, and jaundice. Symptoms develop 4 to 21 days after a mosquito or rodent bite (depending on the disease). This disease is contagious, and patients with suspicious symptoms should be quarantined. However, viral cultures with polymerase chain reaction identification, serol ogy, and immunohistochemistry of tissue specimens are possible.

The initial recommended dose is 25 or 50 mg; therapy is continued until lesions have resolved fungus no more cheap nizoral 200 mg with visa. Adverse effects include hypertriglyceridemia and mucocutaneous effects such as dryness of the eyes, nasal and oral mucosa, chapped lips, cheilitis, epistaxis, xerosis, brittle nails, and burning skin. Acitretin should not be used in women of childbearing potential unless they use effective contraception for the duration of therapy and for 3 years after drug discontinuation. Cyclosporine is signifi cantly more effective than etretinate and has similar or slightly better efficacy than methotrexate. When discontinuing cyclosporine, a gradual taper of 1 mg/kg/day each week may prolong the time before relapse when compared with abrupt discontinuation. Because more than half of patients stopping cyclosporine relapse within 4 months, patients should be given appropriate alternative treatments shortly before or after discontinuing cyclosporine. Adverse effects include neph rotoxicity, hypertension, hypomagnesemia, hyperkalemia, hypertriglyceridemia, hypertrichosis, and gingival hyperplasia. It is more effective than acitretin and has similar or slightly less efficacy than cyclosporine. Adverse effects include nausea, vomiting, stomatitis, macrocytic anemia, and hepatic and pulmonary toxicity. Nausea and macrocytic anemia may be reduced by giving oral folic acid 1 to 5 mg daily. Methotrexate should be avoided in patients with active infections and in those with liver disease. It is an abortifa cient and teratogenic and is contraindicated in pregnancy (pregnancy category X). It is indicated for psoriatic arthritis and treatment of adults with mod erate to severe chronic plaque psoriasis who are candidates for systemic therapy or phototherapy. The recommended dose for psoriatic arthritis is 40 mg subcutaneously every other week. The recommended dose for adults with plaque psoriasis is an initial dose of 80 mg, followed by 40 mg every other week starting 1 week after the initial dose. The most common adverse reactions are infections (eg, upper respiratory and sinusitis), injection site reactions, headache, and rash. Unlike the chimeric infliximab, etanercept is fully humanized, minimizing the risk of immunogenicity. It can be used in combination with methotrexate in patients who do not respond adequately to methotrexate alone. The recommended dose for psoriatic arthritis is 50 mg subcutaneously once per week. For plaque psoriasis, the dose is 50 mg subcutaneously twice weekly (administered 3 or 4 days apart) for 3 months, followed by a maintenance dose of 50 mg once weekly. Adverse effects include headaches, fever, chills, fatigue, diarrhea, pharyngitis, and upper respiratory and urinary tract infections. Hypersensitivity reactions (urticaria, dyspnea, and hypotension) and lymphoproliferative disorders have been reported. Alefacept is approved for treatment of moderate to severe plaque psoriasis and is also effective for treatment of psoriatic arthritis. Adverse effects are mild and include pharyngitis, flulike symptoms, chills, dizziness, nausea, headache, injection site pain and inflammation, and nonspecific infection. The recommended dose for patients weighing 100 kg or less is 45 mg initially and 4 weeks later, followed by 45 mg every 12 weeks. For patients weighing 100 kg or more, the dose is 90 mg initially and 4 weeks later, followed by 90 mg every 12 weeks. Common adverse effects include upper respiratory infections, headache, and tiredness. Combination Therapies Combination therapy may be used to enhance efficacy or minimize toxicity. The combination product containing calcipotriene and betamethasone dipropionate ointment (Taclonex) is effective for relatively severe psoriasis and may also be steroid sparing. The typical dose is 1 g daily, with a gradual increase to 2 g daily as needed and as tolerated. Adverse effects include bone marrow suppression, lesional erythema, localized tenderness, and reversible hyperpigmentation. Severity scores are rated as less than 12 (mild), 12 to 18 (moderate), and more than 18 (severe). Initial dramatic response may be achieved with some agents, such as corticosteroids. However, sustained benefit with pharmacologically specific antipsoriatic therapy may require 2 to 8 weeks or longer for clinically meaningful response. Schwinghammer Adrenal gland disorders 18 Hyperfunction of the adrenal glands involves excess production of the adrenal hormones cortisol (resulting in Cushing syndrome) or aldosterone (resulting in hyperaldosteronism). Fat accumulation in the dorsocervical area (buffalo hump) is nonspecific, but increased supraclavicular fat pads are more specific for Cushing syndrome. Transsphenoidal resection of the pituitary tumor is the treatment of choice for Cushing disease. Pharmacologic Therapy Pharmacotherapy is generally used as secondary treatments in preoperative patients or as adjunctive therapy in postoperative patients awaiting response. Rarely, mono therapy is used as a palliative treatment when surgery is not indicated. This can increase androgenic and mineralocorticoid hormones, resulting in hypertension, acne, and hirsutism. Nausea, vomiting, vertigo, headache, dizziness, abdominal discomfort, and allergic rash have been reported after oral administration. Metyrapone is currently available through the manufacturer only for compassionate use. It also has antiandrogenic activity, which may be beneficial in women but can cause gynecomastia and decreased libido in men. Because it is only available in a parenteral formulation, use is limited to patients with acute hypercortisolemia requiring emergency treatment. Side effects of severe sedation, nausea, ataxia, and skin rashes limit aminoglutethimide use in many patients. Other steroido genesis inhibitors offer greater efficacy with fewer side effects; if aminoglutethimide is used, it should be coadministered with another steroidogenesis inhibitor (usually metyrapone) due to high relapse rates with aminoglutethimide monotherapy. Similar to ketoconazole, mitotane takes weeks to months to exert beneficial effects. Sustained cortisol suppression occurs in most patients and may persist after drug discontinuation in up to one third of patients. Mitotane degenerates cells within the zona fasciculata and reticularis; the zona glomerulosa is minimally affected during acute therapy but can become damaged after longterm treatment. Nausea and diarrhea are common at doses greater than 2 g/day and can be avoided by gradually increasing the dose and/or administering it with food. Consequently, agents that target these transmitters have been proposed for treatment of Cushing disease, including cyproheptadine, bromocriptine, cabergoline, valproic acid, octreotide, rosiglitazone, and tretinoin. None of these drugs have dem onstrated consistent clinical efficacy for treating Cushing syndrome. However, side effects such as sedation and weight gain significantly limit its use. It is approved for treatment of adults with Cushing disease for whom pituitary surgery is not an option or has not been curative. Evidence suggests that mifepristone is highly effec tive in reversing the manifestations of hypercortisolism. Monitor steroid secretion with all drug therapy and give corticosteroid replacement if needed. Mirtazapine and progestins (eg, medroxyprogesterone acetate, megestrol acetate) have also been reported to induce secondary adrenal insufficiency. Secondary disease typically presents with normal mineralocorticoid concentrations. Hyperpigmentation is usually not seen in secondary adrenal insufficiency because of low amounts of melanocytestimulating hormone. An increase to a cortisol level of 18 mcg/dL or more (500 nmol/L) rules out adrenal insufficiency. A normal cosyntropinstimulation test does not rule out secondary adrenal insufficiency.
