Counseling patients on lifestyle changes is important at any blood pressure level and includes weight loss order levitra plus 400mg otc erectile dysfunction treatment in pune, limitation of alcohol intake discount 400 mg levitra plus otc erectile dysfunction essential oils, increased aerobic physical activity 400mg levitra plus fast delivery erectile dysfunction causes wiki, reduced sodium intake, cessation of smoking, and reduced intake of dietary saturated fat and cholesterol. For those with prehypertension (blood pressure 120-139/80-89 mm Hg), lifestyle modifications are the only interventions indicated unless they have another comorbid condition, such as heart failure or diabetes, which necessitates use of an antihypertensive. For most patients, a low dose of the initial drug of choice should be admin- istered slowly, titrating upward at a schedule dependent on the patient’s age, needs, and responses. The target blood pressure typically is 135/85 mm Hg, unless the patient has diabetes or renal disease, in which case the target would be lower than 130/80 mm Hg. A long-acting formulation that pro- vides 24-hour efficacy is preferred over short-acting agents for better compliance and more consistent blood pressure control. Because they are associated with a decrease in mortality in all types of patients, thiazide diuretics should be considered in all patients with hypertension who do not have compelling contraindications to this class of drugs. Both thiazide diuretics and beta-blockers should be used first in patents with uncomplicated hypertension, unless there are specific compelling indications to use other drugs. It is critical to tailor the treatment to the patient’s personal, financial, lifestyle, and medical factors, and to periodically review compliance and adverse effects. Selected Causes of Secondary Hypertension The most common cause of secondary hypertension is renal disease (renal parenchymal or renal vascular). Renal artery stenosis is caused by athero- sclerotic disease with hemodynamically significant blockage of the renal artery in older patients or by fibromuscular dysplasia in younger adults. The clinician must have a high index of suspicion, and further testing may be indicated, for instance, in an individual with diffuse atherosclerotic disease. Potassium level may be low or borderline low in patients with renal artery stenosis caused by second- ary hyperaldosteronism. A captopril-enhanced radionuclide renal scan often is helpful in establishing the diagnosis; other diagnostic tools include mag- netic resonance angiography and spiral computed tomography. The classic clinical findings are positive family history of polycystic kidney disease, bilateral flank masses, flank pain, elevated blood pressure, and hematuria. Other causes of secondary hypertension include primary hyperaldosteronism, which typically will cause hypertension and hypokalemia. Anabolic steroids, sym- pathomimetic drugs, tricyclic antidepressants, nonsteroidal anti-inflammatory agents, and illicit drugs, such as cocaine, as well as licit ones, such as caffeine and tobacco, are included in possible secondary causes of hypertension. The cause of obstructive sleep apnea is a critical narrowing of the upper air- way that occurs when the resistance of the upper airway musculature fails against the negative pressure generated by inspiration. In most patients, this is a result of a reduced airway size that is congenital or perhaps complicated by obesity. These patients frequently become hypoxic and hypercarbic multi- ple times during sleep, which, among other things, eventually can lead to sys- temic vasoconstriction, systolic hypertension, and pulmonary hypertension. The patient will have a widened pulse pressure with increased systolic blood pressure and decreased diastolic blood pressure, as well as a hyperdynamic precordium. Glucocorticoid excess states, including Cushing syndrome, and iatro- genic (treatment with glucocorticoids) states usually present with, thinning of the extremities with truncal obesity, round moon face, supraclavicular fat pad, purple striae, acne, and possible psychiatric symptoms. An excess of corticosteroids can cause secondary hypertension because many glucocorti- coid hormones have mineralocorticoid activity. Dexamethasone suppression testing of the serum cortisol level aids in the diagnosis of Cushing syndrome. Coarctation of the aorta is a congenital narrowing of the aortic lumen and usually is diagnosed in younger patients by finding hypertension along with discordant upper and lower extremity blood pressures. Coarctation of the aorta can cause leg claudication, cold extremities, and diminished or absence of femoral pulses as a result of decreased blood pressure in the lower extremities. Carcinoid tumors arise from the enterochromaffin cells located in the gastrointestinal tract and in the lungs. Clinical manifestations include cutaneous flushing, headache, diarrhea, and bronchial construction with wheezing. Pheochromocytoma is a catecholamine-releasing tumor that typically pro- duces hypertension. Clinical manifestations include headaches, palpitations, diaphoresis, and chest pain. Other symptoms include anxiety, nervousness, tremor, pallor, malaise, and, occasionally nausea and/or vomiting. Thus, in the evaluation of newly diagnosed hypertension, orthostatic blood pressure measurements may be helpful. Which of the following would most likely provide prognostic information regarding this patient? Which of the following antihypertensive agents are generally considered first- line agents for this individual? The central obesity, abdominal striae, hirsutism, and easy bruis- ability are consistent with Cushing syndrome, a disease of adrenal steroid overproduction. Prognosis in hypertension depends on the patient’s other cardio- vascular risks and observed end-organ effects from the hypertension. Thiazide diuretics and beta-blockers are generally considered first-line agents for uncomplicated hypertension because of their effect in reducing cardiovascular mortality and their cost-effectiveness.

This page intentionally left blank Case 10 A 39-year-old man is brought to the emergency room by ambulance after he was found wandering in the street in a disoriented state. She reports that for the last several months he has been complaining of intermittent headaches and palpitations, and he had experienced feelings of lighthead- edness and flushed skin when playing basketball. Three weeks ago, he was diagnosed with hypertension and was started on clonidine twice per day. He took the clonidine for 2 weeks, but because the drug made him feel sedated, he was instructed by his physician 5 days ago to stop the clonidine and to begin metoprolol twice daily. On examination, he is afebrile, with heart rate 110 bpm, respiratory rate 26 breaths per minute, oxygen satura- tion 98%, and blood pressure 215/132 mm Hg, equal in both arms. He is agitated and diaphoretic, and he is looking around the room but does not appear to recognize his wife. His pupils are dilated but reactive, and he has papilledema and scattered retinal hemorrhages. He moves all of his extremities well, his reflexes are brisk and symmetric, and he is slightly tremulous.

At that time neither Cass Mann nor Stuart Marshall realised that they had stepped onto a minefield buy levitra plus 400 mg low price erectile dysfunction causes medscape. From the first meeting cheap levitra plus 400mg online erectile dysfunction foods that help, the organisation was infiltrated by people loyal to the pharmaceutical companies discount levitra plus 400 mg broccoli causes erectile dysfunction. At one meeting, apparently acting on behalf of a drug company, a doctor announced that he could offer the organisation £25,000, to fund an administrator. Mann was amazed that a National Health doctor, who was meant to be independent of the drugs companies, could offer a small voluntary sector organisation £25,000 on behalf of a pharmaceutical company. In 1987, Mann and Marshall together with Dietmar Bollef and Simon Martin set up Positively Healthy. Both Stuart Marshall and Cass Mann had a fiery determination which, as time went on, they were going to need. My work is getting people to celebrate: to stop them from being attendants at their own funeral. People were dying of loneliness and fear, as much as they were dying of opportunist infections, Mann maintains. Those who have bought the story that cancer inevitably kills often cannot see beyond that, or break away from the damaging aspects of a self-destructive life-style. Gay men have become frivolous entertainment queens, self-parodying creatures of the night, which is not what we should be. The practice of allopathic medicine in the institutions of our major cities, he maintains, is programming people to die. The only ones who stand any chance of surviving are those who take part in the new paradigm. Everyone knows that cancer can be treated by numerous different kinds of alternative treatments, but within the present medical treatment paradigm, they are killing people. The Practice of Positively Healthy People ought to have the information which makes them doubt. Positively Healthy began by holding monthly workshops, to which guest speakers were invited. They were proud of the fact that they worked only with statistics and verifiable information taken from the best scientific sources. Positively Healthy was from the start a political organisation; its weekend workshops produced politicised discourses. The workshops also taught simple health-enhancing techniques, like meditation, and generated information about diet and vitamins. As well as the workshops, Positively Healthy organised public meetings and day-long seminars. Within no time, Positively Healthy was assailed by difficulties which undermined its very existence. In April 1988, the organisation was told that its adverts and articles were not wanted in the Pink Paper, the only national paper for gay people. Slowly it began to dawn on Cass Mann and Stuart Marshall that behind the scenes a few individuals were waging a campaign against them. One of the prominent behind-the-scenes critics of Positively Healthy was Duncan Campbell. Although Cass Mann had heard that it was Campbell who had persuaded the editors and owners of the Pink Paper against Positively Healthy adverts, neither he nor Stuart Marshall knew him. Evan Jones was a gay man who had been involved in Positively Healthy from its inception. At the wake, Cass Mann was told that Campbell was making disparaging remarks about the photographs. Looking back on that moment of meeting Campbell, Mann thinks that Campbell must have kept an agenda from that time: Positively Healthy plus charismatic guru, alternative medicine and dietary advice equals anti-rational orthodox treatment. I was cleaning up the mess, the vomit and talking him out of suicide all the time. Mainly I was trying to persuade him 11 into alternative therapies which he always refused. The people who took part in the initial meetings which formulated its policy were members of the gay and lesbian left. By the end of 1988, the paper was running into financial difficulties and against the wishes of both founders it was bought out by Kelvin Sollis, a north London gay businessman. All the papers, files and correspondence in the Pink Paper offices were destroyed. No information about its early financing or its relationship with commercial concerns survived. Alan Beck, a drama lecturer at the University of Kent, joined the new Pink Paper in February 1988, becoming its senior writer responsible for the weekly editorial. In contrast to Cass Mann, Alan Beck had for a long time been steeped in the politics of the gay movement. He was a die-hard political campaigner for the rights of gay men, an organiser and an activist. When Alan Beck talks about the gay community, he speaks with a voice from the street. He is also light years away from the ideas and activities of the high profile media-friendly respectable gays whom he sees as inhabiting a rarified and still quiescent area of gay life, a world which often protects the anonymity of its members. Beck would organise and agitate for gay rights at work or in housing in much the same way as other grass-roots political organisers have fought for other civil rights. He respects socialist activists and campaigners like Peter Tatchell, rather than members of the essentially liberal gay intelligentsia like Duncan Campbell. From that time, he can count three decades of struggle, and discuss milestones, victories and set-backs. His view of the late sixties and early seventies is still optimistic and he chooses to highlight the 12 good things which grew out of that period. Like the film maker Derek Jarman, Beck emphasises the communality of the period and the social ideas it generated.
