Emerging Strategies in HIV PreventionHIV infection continues to exact a devastating toll worldwide.Advances in antiretroviral therapy have helped bring theHIV/AIDS epidemic under control in developed countries.Antiretroviral drugs, however, are not widely available inthose developing countries where HIV poses a catastrophicthreat. Effective strategies for HIV prevention are thereforecrucial to curbing the global epidemic. Vaccination, microbicideuse, and male circumcision are 3 key preventive interventions.Current research is focused on developing effective vaccinesand microbicides and on determining the extent to whichcircumcision helps prevent HIV acquisition and transmission.[Infect Med. 2008;25:63-72]

Why patients with asthma should be given a trial of controller therapyAbstract: There is convincing evidence that controller therapies, such as inhaled corticosteroids and leukotriene receptor antagonists, provide many benefits to patients with asthma. These benefits include decreased symptoms, improved lung function, reduced frequency of exacerbations, and improved quality of life. Even patients with mild asthma and normal lung function can benefit from controller therapy. A recent analysis of the burden of asthma suggests that the proportion of patients who have mild intermittent disease is much smaller than previously estimated and that many more patients have persistent asthma. This finding, in combination with the considerable variability of patient responses to therapy and the difficulty in predicting which patients will respond, underscores the importance of considering a trial of controller therapy in patients with asthma.

Inside the Southeast Michigan ePrescribing InitiativeDespite clear evidence of its benefits, widespread adoption of electronic prescribing (ePrescribing) has been slow. The vast majority of prescriptions are still written by hand, a process plagued with errors and inefficiencies. The Southeast Michigan ePrescribing Initiative (SEMI), a collaborative effort of employers, health plans, physician groups, and others, was launched in 2005 to speed the adoption of ePrescribing. SEMI has accomplished much in 4 years, enrolling more than 3000 physicians who have transmitted nearly 9.5 million electronic prescriptions while improving patient safety and winning over physicians.

Benign Prostatic Hyperplasia:Traditionally, urologists have cared for patients with benign prostatic hyperplasia (BPH). However, because of demographic fluctuations, changes in the health care system, and the development of effective pharmacologic therapy for BPH, primary care physicians are increasingly involved not only in initial patient evaluation but also in continuing management. Here we provide guidelines for treatment of uncomplicated BPH--with special emphasis on medical therapies.

A practical evidence-based approach to rhinosinusitisAbstract: Rhinosinusitis affects millions of persons annually and has a marked impact on quality of life and work productivity. Chronic rhinosinusitis (CRS) is characterized by symptoms that last at least 12 weeks. The history and physical examination should include a search for underlying conditions, such as allergic or nonallergic rhinitis and nasal polyposis. An evaluation of underlying immunodeficiency is warranted in certain patients, particularly those with severe or difficult-to-treat disease or other recurrent infections. When radiologic evaluation is indicated, coronal sinus CT scanning is the procedure of choice. While antibiotics are indicated for bacte- rial rhinosinusitis, intranasal corticosteroids represent the mainstay of treatment for CRS and are particularly useful when polyp disease is present. Nasal irrigation with a saline solution can be a very beneficial adjunctive therapy. Depending on coexisting conditions, additional treatments may include antihistamines, leukotriene modifiers, and immunotherapy. (J Respir Dis. 2006;27(9):372-379)

Prompt diagnosis and therapy are keys to reducing mortality Extrapulmonary tuberculosis, part 5: Pericardial involvement key words: Tuberculosis, Pericarditis, Pericardial effusionabstract: Tuberculous pericarditis, while relatively rare in the United States, is an important cause of pericardial disease in countries where tuberculosis is prevalent. Patients are most likely to present with chronic disease--effusive and/or constrictive. Those with effusive pericarditis often present with tamponade. Patients with constrictive pericarditis exhibit features of systemic and pulmonary venous congestion. An elevated level of adenosine deaminase in pericardial fluid is a good marker for tuberculosis. The presence of granulomas or case-ation necrosis in pericardial tissue confirms the diagnosis. If treatment of effusive tuberculous pericarditis is delayed, constrictive or effusive-constrictive disease usually develops, resulting in a high mortality risk. In addition to a standard antituberculosis regimen, treatment of tuberculous pericarditis may include adjuvant therapy with corticosteroids, pericardiocentesis, and/or pericardiectomy.
