The clinical response rather than results of stool tests should be used to guide the response to therapy. Nitazoxanide is not teratogenic in animals but no data on use in human pregnancy are available. Limited information is available about the teratogenic potential of paromomycin, but oral administration is associated with minimal systemic absorption, which may minimize potential risk. However, one study identified an increased risk of congenital malformations, and specifically hypospadias, among 683 women with exposure to loperamide early in pregnancy.

On the basis of limited data, the maturation process is completed in approximately 1 to 2 days but might occur more rapidly in some settings. Clinical Manifestations the most common manifestation is watery, non-bloody diarrhea, which may be associated with abdominal pain, cramping, anorexia, nausea, vomiting, and low-grade fever. The diarrhea can be profuse and prolonged, particularly in immunocompromised patients, resulting in severe dehydration, electrolyte abnormalities such as hypokalemia, weight loss, and malabsorption. It is the only agent whose use is supported by substantial published data and clinical experience. Single-agent therapy with pyrimethamine has been used, with anecdotal success for treatment and prevention of isosporiasis. For patients with documented sulfa intolerance or in whom treatment fails, use of a potential alternative agent (typically pyrimethamine) should be considered. Chemoprophylaxis probably can be safely discontinued in patients without evidence of active I.

Moreover, Britain had managed to acquire this position at only moderate cost during the relatively peaceful nineteenth century. Mackinder: the Heartland Theory Then and Now," Journal of Strategic Studies 22: 2-3 (1999): 15-38. Nor could Britain use its existing coal bunkering network to control naval refueling, "and unless therefore we take early steps to convert our coaling stations to oil stations we shall risk losing, to some extent, the means of bunker control of neutrals which was so valuable in the recent war when coal was in general use. Just the physical infrastructure alone, including coal mines at home or coaling stations abroad, represented sunk costs that Britain could not easily liquidate since the fate of coal industry was as much a political and economic quandary as a strategic dilemma. The rise of oil undermined the very basis of the Pax Britannica, which one historian describes as resting upon "trade, colonies, and the navy. Britain had been running a trade deficit since the 1880s following the economic rise of the United States and Germany, and it only balanced its current account through exports to captive markets in Asia such as India and earnings from invisible income. It could subordinate itself to the United States to secure reliable oil supplies in wartime. This was hardly advisable if, as policymakers in both London and Washington feared, U. One political scientist describes Britain as the "Saudi Arabia of coal" during the nineteenth century not just because of the extent, but also the quality, of its reserves (Welsh coal being ideally suited for naval boilers). Quoted in: John Maurer, "Fuel and the Battle Fleet: Coal, Oil, and American Naval Strategy, 1898-1925," Naval War College Review 34: 6 (1981): 62. Navy colliers around the Cape Horn (the Panama Canal not being completed until 1914), refueling at British coaling stations, and resupply at sea from British colliers. After the First World War, oil did more than just solidify the supremacy of the U. The existence of plentiful, high-quality oil supplies in California also radically upset the balance of power in the Pacific in favor of the United States, at the expense of both Britain and Japan. As one historian concludes, "Oil would be the foundation of American overseas expansion much as coal served to underpin British imperial policy. The argument here is not that Britain made the wrong choice in 1912 when the Royal Navy shifted to oil. For Britain, in 14 15 Ian Lesser, Resources and Strategy (Basingstoke: Macmillan, 1989), 25. Neither option was especially palatable, and both of them would have sooner or later resulted in the erosion of British strength. Although it had some control over the timing, London could not indefinitely delay the conversion of the Royal Navy from burning coal to oil due to advances in naval technology, for a coal-burning fleet would have been at a major tactical disadvantage against oil-fueled rivals. Germany was hardly in a better position, even if its synthetic petroleum and domestic oil industries provided it with a margin of security unavailable to its rival across the English Channel. Unlike Britain, it could not even consider relying on overseas imports during wartime. German analysts had deluded themselves into thinking that Romania could be a reliable wartime supplier in spite of ample evidence that oil production there had peaked in 1936. The Third Reich proved incapable of arresting this downward trend, not the least because Romania had no interest in turning over its oil industry to a new set of foreign owners or losing the diplomatic and economic leverage that came from being the only oil-producer of consequence in Europe. After 1939, the Third Reich had no option except to expend inordinate amounts of resources to secure and transport relatively small quantities of oil. Germany invested billions of Reichmarks, millions of tons of coal and steel, and the labor of tens of thousands of skilled and slave laborers to construct its synthetic fuel industry. The vast synthetic production facilities, which often produced a variety of synthetic products besides petroleum, including rubber or chemicals such as ammonia and methanol, were also vulnerable to bombing. Production could even be disrupted indirectly by attacks on the railway lines and distribution hubs that supplied these facilities with the coal and steel they needed to function, and which carried their output to consumers across Axis Europe. In the case of the former, we are speaking of the revolutionary application of tanks supported by mechanized infantry and close air-support that interwar theorists (in Germany and elsewhere) designed to overcome the stalemate of the First World War, and which supposedly brought France to its knees in six weeks. In the case of the latter definition, we are 17 For additional information concerning the extent of prewar capital, material, and labor investment in the German oil industry (both natural and synthetic), as well as detailed information concerning production, imports, and consumption, see: Chiefs of Staff Committee, Technical Sub-Committee on Axis Oil, Oil as a Factor in the German War Effort, 1933-1945, 08 March 1946, A.

It would therefore be difficult for clinicians and researchers to learn from one case to the next or to decide how best to help each person with unusual symptoms or combinations of symptoms. For instance, Kitty Dukakis, wife of 1988 Democratic presidential candidate Michael Dukakis, suffered from depression (Dukakis & Scovell, 1991). To say that someone has a diagnosis of depression effectively communicates to a mental health professional that the patient has a particular constellation of symptoms. When a clinician hears that Kitty Dukakis suffered from depression, for instance, the clinician can infer that she has some or all of the following symptoms: depressed mood, reduced pleasure in activities, fatigue or tiredness, a sense of worthlessness, difficulty concentrating, recurrent thoughts about death, and significant changes in appetite, sleep, and energy level (American Psychiatric Association, 2000). Notice how long this list of symptoms is-the term depression conveys much of the needed information more succinctly. Depression, for instance, can further be specified as either a single-that is, first-episode or as a recurrence. A diagnosis of recurrent depression implies a heightened neurological and/or cognitive vulnerability to depression and a longer and more variable course, and it indicates that the disorder may require multiple types of treatments in order to reduce symptoms (Peterson et al. Despite treatment, Kitty Dukakis suffered numerous bouts of depression, which suggests that many types of factors contributed to her disorder and that she was at significant risk for additional episodes. If there were no diagnoses, then how would researchers be able to study mental illness and its treatment Not only did Kitty Dukakis suffer from depression, but she was also dependent on amphetamine pills-"uppers"-and alcohol (Dukakis & Tye, 2006). Some researchers investigate differences between people who suffer from both depression and substance abuse (as Dukakis did) and those who suffer only depression. Researchers have also examined the effect of substance abuse on the course of depression (Agosti & Levin, 2006). Without a classification system for psychological disorders, the problems that Pete Wentz, Carolina Reston, and Keith Urban appear to have suffered from-bipolar disorder, anorexia nervosa, and substance abuse, respectively-would be nameless. Among other purposes, a classification system allows clinicians to diagnose and treat symptoms more effectively, allows patients to know that they are not alone in their experiences, and helps researchers to investigate the factors that contribute to psychological disorders and to evaluate treatments. Such comparisons are possible only because the diagnoses are part of a classification system. For example, children diagnosed with a learning disorder may receive special accommodations or services at school. For some adults, a diagnosis may allow them to have special accommodations at home or work or to receive certain services paid for by their health insurance plan or by government programs. For some people involved in criminal justice proceedings, a diagnosis of a psychological disorder, such as schizophrenia, may make the difference between being sent to a mental health facility and going to prison or jail. People may derive a measure of comfort from merely being given a label for their problems-knowing not only that there is a term for their disturbing thoughts, feelings, and behaviors, but also that they are not the only one with the specific difficulties. Moreover, once they have a name for the symptoms they are experiencing, they can learn more about the disorder and treatments for it. For much of her adult life, she had suffered from insomnia, panic attacks, and intense fear. Then, six years ago, a nightmare triggered memories of childhood sexual abuse and she was finally diagnosed with posttraumatic stress disorder. For example, clinicians may be biased to make-or not make-particular diagnoses for certain groups of people. Relatives and friends, as well as patients, often struggle to answer this question: Does having a psychological disorder exempt patients from being responsible for their behavior Diagnostic Bias A diagnostic bias is a systematic error in diagnosis (Meehl, 1960). Such a bias can cause groups of people to receive a particular diagnosis disproportionately, on the basis of an unrelated factor such as sex, race, or age (Kunen et al. Studies of diagnostic bias show, for example, that in the United States, black patients are more likely than white patients to be diagnosed with schizophrenia instead of a mood disorder (Abreu, 1999; Garb, 1997; Neighbors et al. Black patients are also prescribed higher doses of medication than are white patients (Strakowski, Shelton, & Kolbrener, 1993). Clinical Diagnosis and Assessment 7 7 pathological, and thus be more likely to diagnose a psychological disorder.

Director, Vision Rehabilitation Service Almost daily, individuals with visual impairments confront eye care professionals with questions concerning operating a motor vehicle. Iowa Visual Acuity: (Bioptic Telescopes not allowed to achieve the visual acuity standards noted) > 20/40 in one or both eyes No restrictions 20/41-20/70 in one or both eyes No driving when headlights are required - Behind the wheel testing can be requested via discretionary review process to gain privilege to drive when headlights are required. This standard states that the individual is legally qualified to drive, until their license comes up for renewal, regardless of whether their visual acuity or visual field becomes impaired during the interval between licensing renewal. Although individuals with acquired visual impairments are legally qualified to drive until their license is up for renewal, civil liability exposure exists if they continue to drive with the knowledge that they would no longer visually qualify to drive, if they attempted to renew their license. At such time the vehicle is no longer used for the transport of the passenger or operator that is the subject of the exemption, the exemption expires and may not be used on any replacement vehicle purchased after July 3, 2012. The owner of the vehicle to which the exemption applied must return the vehicle to conformance with the minimum standard of transparency within 60 days of expiration of the exemption.
