Schmid Counterterrorism Bookshelf: 62 Books on Terrorism & Counter-Terrorism-Related Subjects. Now in its fourteenth year, Perspectives on Terrorism has nearly 8,900 registered subscribers and many more occasional readers and website visitors worldwide. The Articles of its six annual issues are fully peer-reviewed by external referees while its Research and Policy Notes, Special Correspondence, Resources and other content are subject to internal editorial quality control. The frst research article, by Joseph Franco, draws lessons from the 2017 Battle for Marawi in the Philippines that can help identify alternative measures to detect sources of violent extremism, such as the responsiveness of local governments, poverty levels, and the efectiveness of educational institutions. Next, Abhinav Pandya examines how Kashmir is becoming increasingly vulnerable to the infuence and operations of transnational terrorist groups. In the frst of these, Michael Furstenberg and Carolin Gorzig apply a conceptual framework of organizational learning to explain the strategic evolution of jihadist groups, particularly Al-Qaeda and Hayat Tahrir al-Sham. Next, Linda Wendelberg examines whether the psychological condition known as Existential Anxiety could be a risk factor in radicalization processes. And this section concludes with a Research Note by Meili Criezis, examining the ways in which Islamic State supporters on Telegram, an encrypted messaging application, renegotiate gender boundaries. The Resource section begins with a book review by Alex Schmid of the recently published Handbook of Terrorism and Counter Terrorism Post 9/11. Ten Joshua Sinai presents more than 60 books by listing their tables of contents, while Associate Editor Judith Tinnes continues her series of extensive hand-searched bibliographies with one on deradicalisation research, and another on terrorism and Iran. The next issue of the journal is tentatively scheduled as a Special Issue on terrorism in the North Caucasus region, guest edited by Julie Wilhelmsen from the Norwegian Institute of International Afairs. This article highlights the need to identify alternative measures to detect sources of violent extremism in Mindanao. Greater foresight could be obtained by observing proxy indicators such as the responsiveness of local governments, poverty levels, and the efectiveness of educational institutions. Given the possibility of a resurgence among jihadist-inspired groups, what are the potential indicators that could detect future with Marawis Reliance on security sector-measures such as the number of previous violent incidents has only limited early-warning utility. It may be more productive to look at other indicators such as the responsiveness of local government units, poverty levels, and the efectiveness of educational institutions. It is unlikely that another urban centre in Mindanao would experience a protracted battle like the one in Marawi. Field visits covered the provinces of Misamis Oriental (Cagayan de Oro City), Lanao del Norte (Iligan City), Lanao del Sur (the Islamic City of Marawi and Butig municipality), and Maguindanao. Implementing guidelines covering the hiring of civil servants, budgeting, and the awarding of contracts is not yet fnalised. Lack of clarity over the day-to-day operations of the regional government could stymie much-needed socio-economic interventions. The dominance of political clans in Mindanao is the manifestation of such local-level dysfunctions. The 2019 Philippine midterm elections saw the continuity of dynastic politics, including the use of violence. Brothers Pre and Solitario Salic who were engaged in a rido [clan war] with the incumbent vice governor of Lanao del Sur province, Bombit Adiong. Adiong was able to convince the Philippine Army brigade commander to put pressure on the rival Salic clan. In turn, the Salic clan sought help from their Maute clan relatives in the neighbouring town of Butig. Butig became associated with the terrorist group afer a series of military ofensives in late 2016. Farhana Maute entered the clan into a pyramid scheme in 2012, seeking to launder funds it obtained afer skimming of funds from government infrastructure projects. To protect itself from loan sharks, the clan organised in 2015 an armed group as a defence measure in 2015. During the initial hours of the siege, an 80-strong band of local gunmen he heard speaking in Maranao seized Father Chito Soganub. One Indonesian straggler was captured, days afer the end of major combat operations in the city. The Box has a disproportionately high number of violent incidents in the history of confict in Mindanao. Tese armed individuals ofen act as mercenaries for other political clans, especially in the run-up to a local election. Expectations of receiving fnancial resources from the Middle East, which, however, remain unfulflled, motivated their local hosts. Local Islamic teachers in Lanao del Sur and Maguindanao were actively contesting jihadist narratives at the village level. For instance, the appointment process for youth representatives was haphazard, with some appointees stripped of their designation at the last minute. Delays in infrastructure projects can be the catalyst for frustration among Cotabato City residents and the Bangsamoro as a whole. The command-and-control arrangements for the Cotabato City police force are one example. Without tangible improvements to peace and development, the Bangsamoro constituency may be disillusioned and trigger another cycle of secessionist-inspired violence. Mindanao is no stranger to how violent extremist groups can thrive and exploit governance vacuums. The lack of good governance and the levels of clan confict appear to be the most promising indicators for future with Marawis in central Mindanao. In turn, weak governance structures can incentivise the creation of private militias as a hedge against uncertainty. At worst, what starts as self-organised groups for communal defence can trigger a security dilemma as clans become inadvertently locked in a spiral of escalation with other militias. More than two years afer Marawi, the socio-economic and political context that gave rise to the Maute Group remains largely unchanged. Illicit economic activities by organised crime groups, whether committed directly or in cooperation with militias, can be considered as an indicator. Another quantifable proxy indicator is the presence or absence of an entrenched criminal syndicate in a locality. Instead of focusing primarily on tracking down personalities or groups espousing violent extremist ideology, it may be more prudent to include collection and production of intelligence on organised crime groups in proximity to known militant strongholds. Statistics on municipal or even village-level economic inequality, out-of school youth, and even incidents of fnancial fraud can serve as early-warning indicators. For instance, municipal and village-level statistics on income inequality from confict afected and confict areas can be compared. A succeeding test can entail using the presence of armed confict as a control variable to determine the efect of income inequality. The same two-step process can be repeated for other proposed proxy measures to detect future with Marawis. Getting individuals to join remains a clan-based and community-level activity in Mindanao. It is also very striking that suicide attacks are not a common fxture in the repertoire of Filipino militants. Material gains through terrorist means remain the most potent driver that sustain and incentivise non-state armed groups in the Philippines. Clearly, there are many potential areas of study that can be pursued to head of any future extremisms.

Malnourished patients are also much more prone to the side effects of medications impotence journal discount top avana 80 mg with visa. Given Treatment of Patients With Eating Disorders 49 Copyright 2010 impotence causes cheap top avana 80 mg amex, American Psychiatric Association erectile dysfunction brochure cheapest top avana. With all antidepressants how to avoid erectile dysfunction causes buy cheap top avana on-line, strategies to manage side effects include limiting the use of medications to pa tients with persistent depression erectile dysfunction in diabetes mellitus pdf purchase 80 mg top avana, anxiety 498a impotence proven top avana 80mg, or obsessive-compulsive symptoms; using low initial doses in underweight patients; and remaining vigilant about early manifestations of side effects. Bupropion has been associated with an increased likelihood of seizures in patients with bulimia nervosa (180, 181); although the reason for this is unknown, it is suspected that patients with anorexia nervosa, binge-purge type, may also be at increased risk for seizures. Thus, this medication is not recommended for patients with anorexia nervosa, particularly those who purge. Mirtazapine, an antidepressant associated with weight gain, has also been associated with neutropenia. Thus, mirtazapine may not be suit able for use in underweight anorexia nervosa patients. Although no controlled studies have been reported in pa tients with anorexia nervosa, controlled trials of olanzapine and risperidone are under way. The quality of the available ev idence on using antipsychotic medications is also limited by the fact that studies rarely include male patients and have included only small numbers of adolescents; in addition, only case re ports are available regarding prepubertal children. If antipsychotic medications are used, the possibility of extrapyramidal symptoms, especially in debilitated patients, should be considered and routinely assessed. Other medications have been used to address associated features of anorexia nervosa. However, no good supporting evidence exists to demonstrate the efficacy of this treatment (202, 203). Only in a subset of very-low-weight women (<70% average body weight) did it prevent further bone loss (204). This, in turn, may cause the patient to misunderstand that her body is functioning normally and therefore contribute to denial of the need to gain more weight. Because most bulimia nervosa patients who have been studied are of normal weight, nutritional restoration will not be a central focus of treatment. Thus, even among patients of normal weight, nutritional counseling may be a useful adjunct to other treatment modalities in reducing behaviors related to the eating disorder, minimizing food restrictions, increasing the variety of foods eaten, and encouraging healthy but not compul sive exercise patterns (208). Patients with bulimia nervosa who are overweight or obese have not been well studied. Behavioral techniques, such as planned meals and self-monitoring, may also be helpful for managing initial symptoms and interrupting binge-purge behaviors (213, 214). It should be pointed out that these study results may not be generalizable to typical clinical situations. It is also possible that the narrow inclusion cri teria of some studies limit the generalizability of the study results (216). Some bulimia nervosa patients, particularly those with concurrent personality pathology or other co-occurring disorders, may require substantially longer treatment. Also unknown is how the length and characteristics of the treatments varied according to other clin ical dimensions of these patients. These concerns are often approached in practice through a variety of longer-term psychotherapies. However, clinicians should remain cognizant of the idiosyn cratic recommendations made in some self-help groups. Available studies also suggest that antidepressants may be helpful for patients with substantial symptoms of depression or anxiety, obsessions, or certain impulse disorder symptoms or for patients who have not responded or had a suboptimal response to previous attempts at appropriate psychosocial therapy (228, 229). Thus, many clini cians initiate fluoxetine treatment for bulimia nervosa at the higher dosage, titrating downward if necessary to manage side effects. Side effects vary widely across studies depending on the type of antidepressant med ication used. The toxicity and potential lethality of tricyclic antidepressant overdosage also dictate cau tion in prescribing this class of drug for patients who are at risk for suicide. Although there are data indicating that fluoxetine can be ef fective in preventing relapse in these patients (226), other data suggest that high rates of relapse occur while antidepressants are being taken and possibly higher rates are seen when the medi cation is withdrawn (240). In the absence of more systematic data, most clinicians recommend continuing antidepressant therapy for a minimum of 9 months and probably for 1 year in most patients with bulimia nervosa. Topiramate is not an effective mood stabilizer but may be potentially useful for bulimia nervosa and binge eating disorder (242, 243). Empirically supported strategies for the treatment of binge eating disorder include nutritional counseling and dietary management; individual or group behavioral, cognitive behavioral, dialectical behavioral, psychodynamic, or in terpersonal psychotherapy; and medications. In reviewing the available information on treating binge eating disorder, it is important to consider the focus of treatment. Most programs using nutritional rehabilitation and counseling focus on weight loss as the primary outcome, whereas studies of psychotherapy and medication generally consider reduction of binge eating as the primary outcome measure, with weight loss as a secondary outcome. Addiction-based 12-step approaches, self-help orga nizations, and treatment programs based on the Alcoholics Anonymous model have been tried, but no systematic outcome studies of these programs are available. In sum, there appear to be several good psychotherapeutic options for treating binge eating disorder when a reduction in binge eating is the primary goal. However, several studies suggest that at least for some patients at certain stages of recovery, behavioral weight control may be a useful treatment component. Also, because studies have found that binge eating may begin before obesity or dieting (283), specific approaches are needed for nonobese patients struggling with binge eating symptoms. Heart rate and blood pressure need to be monitored closely in patients taking sibutramine, and the medication should be discontinued if there are significant elevations in these parameters, although these side effects seem to be uncommon (285). Finally, the anticonvulsant medication topiramate appears to be effective in reducing binge eating and promoting weight loss in the short (286) and long (287) term, although side effects such as cognitive problems, paresthesias, and somnolence may limit its clinical utility for some individuals. Dexfen fluramine, although effective for reducing binge eating (289), has been removed from the mar ket because of increased risk of primary pulmonary hypertension and heart valve abnormalities. It is important to note that in several studies, the placebo response rate has been reported to be quite high. Another study found that fluoxetine in the setting of group behavioral treatment did not augment binge cessation or weight loss but did reduce depressive symptoms (294). Thus, the addition of medication to psychotherapy for binge eating disorder is not, in most cases, associated with additional benefit on the core symp tom of binge eating, perhaps because psychosocial treatments are quite effective for this symp tom. Although formal agreed-upon definitions for these syndromes do not yet exist, the construct of night eating syndrome, first described by Stunkard et al. Throughout the out patient care of such patients, communication among professionals is especially important. The focus of treatment may be on addressing quality-of-life issues (rather than on weight changes or more normal eating habits) and providing compassionate care, with the rec ognition that patients can realistically achieve only limited goals (125, 304, 305). Some older patients maintain accurate images of their body and recognize that they are too thin but still need significant help with actually gaining the needed weight or relinquishing a strongly established habit of binge eating or purging. Binge eating disorder is also associated with high rates of lifetime co-occurring substance abuse, which is more prevalent in male (57%) than in female (28%) patients (313). The presence of an ac tive substance use disorder does have implications for the treatment of eating disorders. Patients with co-occurring eating and substance use disorders require longer inpatient stays and are less adherent with treatment after hospitalization than those with substance use disorders alone (322). In everyday clinical practice, substance use shows a strong association with length of treatment required for remission (81). Depressed individuals with an eating disorder experience higher levels of anxiety, guilt, and obsessionality but lower levels of social withdrawal and lack of interest than depressed individuals without eating disorders (328). In a controlled study with a large sample, 71% of women with an orexia or bulimia nervosa had at least one anxiety disorder, a rate significantly higher than that found in the control group (330), although rates for specific anxiety disorders varied (331). Although specific causal links have not been demonstrated and the mechanisms of association and potential transmission remain unclear, it is thought that early trauma may sensitize some individuals to later traumatic experiences and an array of impulsive behaviors, including eating disorder symptoms. In all cases, person ality types and the extent of personality pathology have implications for treatment (79, 351, 352). The presence of borderline personality disorder seems to be associated with a greater disturbance in eating attitudes, a history of more frequent hospitalizations, and the presence of other problems such as suicidal behaviors and self-injurious behaviors (356, 360). The improvement of axis I eating disorder symptoms may produce concurrent improvement in traits associated with these personality dis turbances (364). Although this approach has not yet been systematically studied, clinical con Treatment of Patients With Eating Disorders 59 Copyright 2010, American Psychiatric Association. Recent naturalistic research documents the generally poorer outcome and longer treatment required for bulimia nervosa patients with borderline, avoidant, or more broadly emotionally dysregulated personality pathology, although many such patients do improve substantially with longer-term treatment (365). Type 1 diabetes Eating disorders may be more common among patients with type 1 or type 2 diabetes than among nondiabetic patients (366, 367), but this contention is not strongly supported by re search (368). The presentation of eating disorders in the context of diabetes may be substantially more complex than that seen with an eating disorder alone. In addition, these concurrent diagnoses may present as numerous general medical crises before the presence of the eating disorder is diagnosed and treated, particularly among patients with type 1 diabetes. Lengthy in patient treatment for adult diabetic patients with eating disorders (primarily bulimia nervosa) is promising but has been studied in only a few patients (373). Behaviors associated with eat ing disorders, including inadequate nutritional intake, binge eating, purging by various means, and the use or misuse of some teratogenic medications. Another study found that anorexia and bulimia nervosa patients had a decreased severity of eating disorder symptoms during pregnancy and that patients with bu limia nervosa, but not patients with anorexia nervosa, maintained this improvement through 9 months postpartum (384). Although some patients may be able to eat normally and decrease binge eating and purging during their pregnancy, it is best for the eating disorder to be treated before the pregnancy if possible. In one study, primiparous mothers with an episode of eating disorder during the first postpartum year often expressed negative emotions toward their infants during meals, the infants emotional tone was more negative, and the infants mealtimes were more conflictual than those of control infants (388). In a study of eight women with bulimia nervosa, six of the seven women with active bulimic symptoms showed polycystic ovaries; at follow-up, the five who continued to have bu limic symptoms all had polycystic ovaries, whereas normal ovaries were seen in the three whose bulimia nervosa had remitted (389). Although little is known about the consequences of fertility drugs in patients with anorexia nervosa, the simultaneous multiple pregnancies that often occur with these drugs may be even more difficult for patients with an eating disorder to contend with than for women without an eating disorder. Male gender Although eating disorders are more prevalent in women, males with eating disorders are not rare, and case series often report on hundreds of male patients (390, 391). Studies of national samples of girls and boys exposed to physical and sexual abuse have shown that although binge and purge behaviors were nearly twice as prevalent among girls (13%) as boys (7%), boys who had experienced both physical and sexual abuse were nearly twice as likely as girls to report these behaviors (odds ratios 8. Especially in the bulimia nervosa and binge eating disorder subgroups, males with eating disorders who present to tertiary care cen Treatment of Patients With Eating Disorders 61 Copyright 2010, American Psychiatric Association. As in women, there is a higher risk of osteoporosis in men with eating disorders (398, 399). Studies of binge eating disorder patients demonstrate that women have greater body image dissatisfaction and are more likely to cope with negative affect by binge eating, whereas men have higher rates of drug and alcohol use disorder histories (400). For example, with regard to personality traits, males with eating disorders have somewhat less perfectionism, harm avoidance and reward dependence behaviors, and cooperativeness than females (405). Open blind studies suggest that bringing testosterone levels to within normal ranges in males during nutritional rehabilitation for anorexia nervosa may be helpful in increasing lean muscle mass, but definitive studies on this have not been completed. Although studies in clinical samples have suggested that a higher prevalence of homosexu ality may exist among males with eating disorders (390), this finding has not yet been con firmed epidemiologically. Nevertheless, because issues concerning sexual orientation are not uncommon among males with eating disorders seen in clinical settings, these issues should be considered in treatment (390). Where possible, therapy groups restricted to male patients may address some of these pa tients specific needs and help them deal with potential stigmatization of male patients by fe male patients in treatment. Further, because they are generally taller and larger framed to begin with, males with anorexia nervosa often re quire much larger weight gains to return to a healthy weight (391, 399). These young patients know that they are under weight, would like to be heavier, may not know why this goal is hard to achieve, and usually show more generalized anxiety unrelated to food. Other syndromes to be considered are selective eating disorder, functional dysphasia, and pervasive refusal syndrome (407). With respect to middle-aged patients, case reports and clinical consensus now suggest that as the baby boomer generation grows older, body image concerns and eating disorders are becoming more prevalent. At the other end of the age spectrum, incidence rates for anorexia nervosa among women over age 50 years are low, accounting for <1% of patients with newly diagnosed anorexia ner vosa (421). Cultural factors Specific pressures and values concerning weight and shape vary among different cultures. The quest for beauty and acceptance in accordance with the stereotypes women perceive in contem porary media is leading increasing numbers of women around the world to develop attitudes and eating behaviors associated with eating disorders. Popkin and Gordon-Larsen (428) have described a phenomenon called the nutritional tran sition in economically emerging countries. Female athletes in competitive sports that emphasize a thin body or appearance, such as gymnastics, figure skating, and distance running, are especially at risk, as are female ballet dancers. Certain antecedent factors such as cultural preoccupation with thinness, performance anxiety, and athlete self-appraisal may predispose a female athlete to body dissatisfaction, which may mediate the development of eating disorder symptoms (442).

It is to be differentiated from the pseudomelanosis which is a postmortem artefact of blood in association with bacteria. This specific finding in the brain of sheep has been mistaken for a lesion of a plant poisoning. Such a lesion is nonspecific and can be seen in any tissue destructive lesion as infarcts, hydrocephalus, trauma, infections, etc. Such anomalies are often related to in utero induction by viruses, chemicals, defective genes, etc. Normally, a slight empty space is in this area when the head is removed at the atlantooccipital articulation. An acute space occuping lesion such as an abscess, edema, or meningitis has caused the brain to swell and push outwards. Although brain tumors are space occuping, they usually grow too slowly for edema to develop and cause such a lesion. The paler brain shows wider gyri and more shallow sulci of both the cerebrum and the cerebellum. In addition, the caudal ventral tip (nodulus) of the cerebellum is projecting outwardly and caudally (cerebellar coning). It had actually protruded through the foramen magnum when the skullcap was in place. Any space occupying lesion can cause this, but a brain or meningeal infection are the most common causes. Neither animal was bled out, but apparently the animal with the darker blood filled tissues died in a position with its head lower than the rest of its body to allow for this hypostasis. Hypostatic congestion can sometimes be well marked but it will not leave large pockets or pools of blood on the tissue involved. Because of the hard cover of the brain, which in effect is a semifluid mass, a blow to the outside of the skull in one area often causes a rebound lesion such as this in the area of brain opposite the site of external contact. Such large areas of hemorrhage are usually traumatic, but smaller foci can be from capillary damage by viruses as in hog cholera. In this case, an enzyme needed for the normal metabolism of lipids is deficient or absent. Similar diseases are seen in other species and most are considered hereditary in nature. This failure of proper development has been shown to be caused by embryological viral diseases such as Herpes in the dog and horse, panleukopenia in the cat and hog cholera in the pig. In this case, the entire litter was affected with myoclonia congenita at birth and also had this lesion. The corpus callosum is thinned more on one side than the other, and in general, one side is slightly more affected than the other. Many cystic spaces (porencephaly) in the grey and white matter are seen scattered in the remaining parenchyma. It is to be noted that the more sensitive white matter is more severely affected than the grey matter. This day old piglet was infected in utero with the virus of Japanese B encephalitis. The *H I * 1 lack of neutrophils helps differentiate this viral disease from the suppurative encephalitides usually caused by bacterial agents. Almost any of the viral agents could be involved in this case as it is not a diagnostic lesion by itself. A distinct focus is seen to one side of, not actually associated with, the vessel (gliosis). This is from a natural case in a piglet and is to be differentiated from hog cholera which usually lacks this neutrophilic response in its cuffs and glial nodules. In most cases of a nonsuppurative encephalitis, there are no grossly recognizable lesions in the brain which again helps to differentiate them from bacterial diseases. They may also be found as a diagnostic lesion of cholinesterase inhibition poisoning as vacuolated neurons in the ventral nucleus of the vagus. Closer observation shows it to be degeneration of the wall itself with many of the reactive cells being neutrophils. In some cuffs, not shown here, the reaction may involve only one segment of the wall and not its entire circumference. The neutrophils should make one consider that this could be a bacterial infection or a viral disease that may stimulate more neutrophils than a viral disease usually does. This is a moderate case, as mild cases often have no grossly visible lesion on the surface and severe ones may be covered completely by a sheet of fibrin. Many organisms can cause such a lesion from septicemia or by direct extension as from a middle ear infection. While this was a case of polyserositis, almost any septicemic bacterial disease can cause it as well as extensions from local infections of the middle ear or the nasal cavity. The clear spaces in the brain tissue proper represent edema and possibly some myelin swelling. While it is possible for almost any bacterial agent to be isolated from such a case, it is most prudent to consider first Listeria monocytogenes as in this cattle case. Of note is the fact that cold storage of this brain prior to culture attempts often enhances the chances to isolate the organism. The great majority of acute listeriosis cases do not have gross lesions, but chronic cases such as those treated with antibiotics may have such a lesion as shown above. The granulomatous mass has effectively blocked the aqueduct of Sylvius to cause this acquired hydrocephalus. This photograph is a good case in point to show that a mass or lump is often just that, a lump, until examined further. It is surprising that in the many bacterial vegetative endocarditis cases in domestic animals more emboli do not go to the brain. In general, one should r v * consider a parasitic migration quite likely in any species. This is most commonly seen in dogs of the large breeds such as Great Danes and St. They tend to form, as seen here, over the body of the vertebra leaving the area over the intervertebral discs less involved. Their cause is unknown, although at one time they were considered a sequelae of chronic pachymeningitis. Their dark color is primarily due to bone marrow which has developed in these metaplastic pieces of bone. These are associated with a purulent infection of the adjacent spinal cord with resultant paresis. The pig was down in the rear quarters and had decubital sores on its hocks and tail stump. The amputation of the tail, which may have been caused by tail biting, is considered the source of entry for the Staphylococcus spp. The affected animals act like they have severe cervical cord disease of some type and any forced movements of the head may elicit a pain response. The picture is included here as such a gross lesion may be seen in any animal with an acute bacterial meningitis, a bleeding disorder or trauma to the cord. Many slightly elongated oval areas of vacuolated fibers are easily seen, some of which have bits and pieces of degenerated axon material in them. Just one or two vacuoles in the case of equine wobblers may be all that is seen in the cord to justify the diagnosis. Histologically, neutrophils will be present in the ocular tissues to show that this is an inflammatory process. This lesion in any young animal can almost be considered pathognomonic for septicemia. If one does not look closely, or if the fibrin is also in the posterior chamber, it may be mistaken for a cataract (pathological clouding of the lens), or a pseudocataract that results from chilling, but which clears up when the carcass is rewarmed. This could be the result of a traumatic injury to the cornea with a secondary infection or it could be a primary infection. From this view, one would have to be careful to distinguish it from a clump of fibrin in the anterior chamber (hypopyon). While most cases of goiter are associated with iodine deficiency there are others, such as these, which are related to a plant poisoning caused by members of the Brassicaceae family, rape and kale. These were eaten by the ewe and the lambs were born with the condition, congenital goiter. It should be noted that there is some difficulty in goiter evaluation as twin lambs may be born with one lamb having hyperplastic goiter and the other having colloid goiter. Often in congenital cases at least, hair covered animals may have wool like hair and in wool covered animals, the wool may be more hair like. The large cystic appearance suggests this is cystic goiter and not hyperplastic goiter with cellular proliferation of the follicular epithelium. Iodine deficiency itself or some plant related problem as with rape and kale pastures can be involved. There is a decrease in follicle pressure as indicated by the infolding and collapse of the follicular walls and colloid is absent. Slightly medial and anterior to this, the curved, dark, flattened, atrophic adrenal lies between the kidney and the abdominal vena cava. A normal adrenal is usually more pale and bulges above the peritoneum in an elongated, roundish lump like fashion. Most cases of adrenal atrophy in animals are associated with disuse atrophy such as is commonly seen in captured wild animals. These wild animals often die after a sharp, loud noise or other stress, from adrenal failure to stimulate gluconeogenesis. This adrenal lesion is a progressive one and the adrenal gland lesion may be seen without the other lesions if the animal happened to die from some other intercurrent disease first. The pair of glands set off by themselves are essentially normal and weigh a total of 7. This affected animal had pale muscles with interfascial edema and it had died suddenly with a high fever. Given time and proper conditions they probably would that die suddenly, often following stress. Most have some have died in the same fashion as category one and three fibrin deposition with slight excess fluid in serous cavities. The third in this disease complex, but disuse atrophy can not category pigs do not have muscle or fascial lesions, but be ruled out. This is a relatively common tumor of older animals especially rats and dogs, and, in this case, a bull. Histologically, there is a marked cellular increase (hyperplasia) of the anterior part (pars anterior) of the pituitary, but the cause is not known. This is one of several aged ewes having this lesion that died suddenly with lesions of overeating disease caused by C.

Syndromes

  • How much do you drink each day and how much urine do you produce?
  • Spinal anesthesia. This is also called regional anesthesia. The pain medicine is injected into a space in your spine. You will be awake but will not be able to feel anything below your waist.
  • After the defibrillator paddles (or large patches) are placed on your chest, the defibrillator is activated and an electric shock is delivered to your heart. This shock briefly stops all electrical activity of the heart. Then it allows the normal heart rhythm to return.
  • Benzodiazepines can have many side effects. The most common are daytime drowsiness and a hung-over feeling, which can increase the risk of automobile accidents. Benzodiazepines may also worsen certain breathing problems and can lead to falls in the elderly. Benzodiazepines taken during pregnancy may be associated with birth defects (such as cleft palate).
  • Numbness and tingling
  • Shift work sleep disorder
  • Reactions to medications
  • Your adolescent may have difficulty with a new authority figure entering the situation. This complication can be reduced if someone he or she knows performs the test. Otherwise, your adolescent may show some resistance. Prepare the adolescent in advance for the possibility that the test will be done by someone unfamiliar.
  • Being the first child
  • Trouble keeping fluids down

Most patients had underlying allogeneic hematopoietic-cell transplantation erectile dysfunction zinc buy genuine top avana online, acute leukemia icd 9 code erectile dysfunction neurogenic buy top avana without prescription, or other hematologic diseases homeopathic remedy for erectile dysfunction causes buy top avana pills in toronto. At week 12 erectile dysfunction jackson ms cheap top avana 80mg online, for the modified intention to treat population erectile dysfunction hiv medications order top avana american express, a complete or partial response to therapy (a successful outcome) was achieved in 52 impotence liver disease 80mg top avana. Switches were made because of intolerance or insufficient response in 70% and 24% of the amphotericin B and voriconazole groups, respectively. The application also summarized international guideline recommendations for voriconazole in adults and children. There have also been rare cases of arrhythmia (including torsade de pointes and bradycardia), cardiac arrest, and sudden death in patients taking voriconazole, probably related to excessive plasma concentrations. These cases usually involve patients with multiple confounding risk factors, such as history of cardiotoxic chemotherapy, cardiomyopathy, hypokalemia, and concomitant medications. Peripheral neuropathy may occur after months of therapy, usually sensory, sometimes motor or mixed, and is related to increased doses required to achieve adequate plasma concentrations. The risk for squamous cell skin cancer or melanoma in sun-exposed areas is enhanced by concomitant immunosuppression and chronic voriconazole use, especially in fair skinned persons (11). The Committee acknowledged that voriconazole is currently the recommended treatment of choice for treatment of acute invasive aspergillosis in available guidelines. The Committee recommended that with the addition of new azoles (itraconazole and voriconazole) to the Model Lists, the square box should be removed from the current listing for fluconazole.

The Committee considered the rationale behind the new proposals to delete atazanavir, lamivudine+nevirapine+stavudine, nevirapine and saquinavir formulations to be reasonable and therefore recommended deletion of the items as proposed. It has been recommended for deletion in 2017 in accordance with the 2015 Expert Committee recommendation. Summary of evidence: benefits Evidence for the clinical effectiveness of abacavir was evaluated at the time of listing. The application described a review of abacavir use in paediatric patients by Melroy et al. Summary of evidence: harms Evidence for the safety of abacavir was evaluated at the time of listing. The application also claimed cost savings in terms of reduced shipment, storage and wastage costs. The Committee acknowledged the advantages of dispersible tablets over liquid formulations include easier logistics, lower production costs, and their suitability for use in very young children. Zidovudine capsules have been recommended for deletion in 2017 in accordance with the 2015 Expert Committee recommendation. Summary of evidence: benefits Evidence for the clinical effectiveness of zidovudine was evaluated at the time of listing. Advantages of a dispersible tablet formulation over syrups include easier and lower-cost transport, lower production costs, able to be used in very young children and may be dispersed in breast milk or formula. Summary of evidence: harms Evidence for the safety of zidovudine was evaluated at the time of listing. The application also claims cost savings in terms of reduced shipment, storage and wastage costs compared with oral liquid. Scored tablets also allow greater dosing flexibility across age and weight ranges. Kekitiinwa A, Cook A, Nathoo K, Mugyenyi P, Nahirya-Ntege P, Bakeera-Kitaka S, et al. Summary of evidence: benefits Evidence for the clinical effectiveness of atazanavir and ritonavir was evaluated at the time of (from the application) their individual listings. Summary of evidence: harms Evidence for the safety of atazanavir and ritonavir was evaluated at the time of their individual (from the application) listings. The application described the most common adverse events, warnings and precautions, drug interactions and precautions for special populations associated with atazanavir and ritonavir, with reference to the U. A comparative analysis of the characteristics of available ritonavir-boosted protease inhibitors is presented in the guidelines. The application describes cost savings associated with shipment, freight and storage compared with the oral solution. The oral pellet formulation also has advantages over the oral solution in terms of logistics, storage and less wastage. Less than half of all infected people were receiving antiretroviral therapy in 2015 (1). The proportion of patients with treatment-emergent integrase-inhibitor resistance was a pre specified secondary endpoint. In addition, 174 significantly fewer patients in the dolutegravir group had virological failure due to treatment emergent resistance (4 versus 17 patients; adjusted difference -3. Summary of evidence: harms the safety profile of dolutegravir compared favourably to other antiretrovirals in the (from the application) abovementioned clinical trials. The occurrence of adverse events leading to treatment discontinuation was low and comparable across treatment groups (2, 3). Dolutegravir has also been associated with hepatotoxicity and hypersensitivity reactions (8). Dolutegravir and raltegravir had comparable effects, but were better than elvitegravir+cobicistat in terms of viral suppression and treatment discontinuation. Compared with efavirenz 600 mg, dolutegravir has advantages including lower potential for drug interactions, a shorter median time to viral suppression and a higher genetic resistance barrier. The application claims that with increasing volumes and generic manufacture, the unit price of dolutegravir is expected to decline, and pricing agreements be refined. There was no difference between groups in the proportions of patients who had viral suppression < 400 copies/mL at 96 weeks (86%) (5). The most common drug-related adverse events were reported as headache, nausea, fatigue and diarrhoea. The rates of development of new, recurrent or progressive cancers were similar across treatment groups (3). Elevations in creatine kinase, along with associated rhabdomyolysis and myopathy have been observed with raltegravir. Risk is increased by concomitant administration of other medicines known to increase the risk of these events (7). There have been rare reports of severe, life-threatening and fatal skin reactions with raltegravir including Stevens-Johnson syndrome and toxic epidermal necrolysis. There are limited data on the safety of integrase inhibitors during pregnancy and breastfeeding (7). The Committee considered that dolutegravir was the preferred integrase inhibitor for the majority of patients, but that currently no data exist for the use of dolutegravir in these two populations. Summary of evidence: benefits Evidence for the clinical effectiveness of abacavir and lamivudine was evaluated at the time of (from the application) their listing. Summary of evidence: harms Evidence for the safety of abacavir and lamivudine was evaluated at the time of their listing. The application 180 also claims cost savings in terms of reduced shipment, storage and wastage costs. Less than half of all infected people were receiving antiretroviral therapy in 2015 (2). The pooled results of these trials formed the basis for regulatory approval in Europe and the United States. The primary efficacy endpoint in both studies was the proportion of subjects with viral load less than 50 copies/mL at week 48. This product is currently licensed in Europe, the United States, Canada and Australia. At week 96, the proportions of patients with viral load less than 200 copies/mL were 90. For adverse events related to efavirenz, the proportions of reported adverse events were 39% in the 400 mg group and 48% in the 600 mg group (difference -8. The proportions of patients reporting serious adverse events was not statistically significantly different between treatment groups (2). Countries should discontinue stavudine (d4T) use in first-line regimens because of its well recognized metabolic toxicities (strong recommendation, moderate-quality evidence). Gilead has licencing agreements with generic drug manufacturers in India, South Africa and China, as well as the Medicines Patent Pool, allowing production and sale of generic versions of Gilead medicines in 112 developing countries. The Committee also noted concerns regarding potential drug-drug interactions of this combination with other medicines, particularly rifampicin. Bioequivalence of two co-formulations of emtricitabine/tenofovir alafenamide fixed-dose combinations with 200/10 mg and 200/25 mg. Bioequivalence of the Rilpivirine/Emtricitabine/Tenofovir Alafenamide Single-Tablet Regimen. The Committee considered that triaging patients according to bassline viral load, or switching regimens after achieving viral suppression was not consistent with a public health approach and may not be feasible in resource-limited settings. In addition, the Committee noted that rilpivirine, would not be suitable for patients co-infected with tuberculosis and taking rifampicin. Less than half of all infected people were receiving antiretroviral therapy in 2015 (3). At week 24, switching resulted in no significant difference in maintenance of virologic suppression and met the criteria for non-inferiority. Prevention is specified as mother-to-child transmission and post-exposure prophylaxis. Study populations included serodiscordant couples, people who inject drugs, men who have sex with men, female sex workers, transgender women, heterosexual men and women. A formulation manufactured by Cipla Ltd was added to the list of prequalified medicines on 21 December 2016. The authors concluded that policy makers should consider adopting and implementing this low-cost broad infection prevention package which could save 3. The small number of pediatric patients enrolled in the study makes it difficult to interpret efficacy results in patients 5 to 17 years of age but the available data support use of the half-dose in patients less than 12 years of age and at weighing least 14 kg and use of the full dose in patients 12 to 17 years of age. At that time there was limited evidence available on the use of oseltamivir in patients with severe influenza (Table 1). The effect of oseltamivir in reducing the complications of influenza was originally reported in a pooled analysis of 10 manufacturer-sponsored randomized trials of oseltamivir for the treatment of seasonal influenza, not reporting data on mortality (1). The addition of oseltamivir was based on consideration of not only the randomized trials but also systematic reviews of observational studies. The meta-analysis of observational data examined was published as an independent systematic review and meta-analyses of 74 studies (2). The large effect on mortality was considered a key element in the decision, despite information from observational studies on severely ill patients is at high risk of bias. In 2013 the Expert Committee reviewed all the evidence available to it and decided to retain oseltamivir in the list. Up until then, no randomised trials of severe or complicated patients had been undertaken and this remains the case today. Further, numerous randomised trials on oseltamivir treatment had never been published. However, in 2014 their results become available through protracted investigations and efforts to retrieve unpublished evidence by independent researchers: a systematic review based on a complete set of clinical study reports of clinical trials of oseltamivir used to support applications for regulatory approval was published in the Cochrane Database of Systematic Reviews (3). In 2016 the Cochrane group published a systematic review of observational studies of oseltamivir in hospitalised patients with 2009/A H1N1 influenza infection (4). Manufacturer sponsored studies were also published, including an individual patient meta-analysis of observational data in hospitalised patients with 2009/A H1N1 influenza infection (6). This review included 29 234 patients, from 78 centres, for which information on mortality was available. However this large number represents only a fraction of the potentially available data: of 401 centres contacted, only 77 (19%) agreed to contribute data. As there were no randomised studies of patients with severe influenza, evidence was limited to observational studies primarily of patients hospitalised with 2009/A H1N1 influenza infection to inform on the benefits of oseltamivir for severely ill patients (Table 1). Influenza type C virus is detected much less frequently and usually causes mild infections. Worldwide, these annual epidemics are estimated to result in about 3 to 5 million cases of severe illness, and about 250 000 to 500 000 deaths. In industrialized countries most deaths associated with influenza occur among people age 65 or older (7). Epidemics can result in high levels of worker/school absenteeism and productivity losses. The effects of seasonal influenza epidemics in developing countries are not fully known, but research estimates indicate that about 28. Treatment of uncomplicated disease in healthy individuals is supportive and includes antipyretics, adequate fluid intake, rest, and staying off work or school until 24 hours after resolution of fever to limit spread to others. Inhibitors of the influenza neuraminidase protein (oseltamivir, zanamivir, peramivir and laninamivir which are licensed in several countries). M2 proton channel blockers adamantanes (amantadine and rimantadine), to which virus resistance has been frequently reported, limiting the effectiveness of treatment.
