Benign prostatic hyperplasia (BPH) is a nonmalignant enlargement of the prostate which can result in bothersome lower urinary tract symptoms. The treatment goal for men with BPH is to relieve these bothersome symptoms. ⋯ Tamsulosin provided a small to moderate improvement in urinary symptoms and flow compared to men receiving placebo in men with BPH. Effectiveness was similar to other alpha antagonists and increased only slightly with higher doses. Long term effectiveness and ability to reduce complications due to BPH progression could not be determined. Adverse effects were generally mild but their frequency, including withdrawals, increased substantially with the higher doses that are generally available for treatment.

ReviewBeta-lactam versus beta-lactam-aminoglycoside combination therapy in cancer patients with neutropaenia.
Chemotherapy treated cancer patients are prone to neutropaenia and life-threatening infections. Early, empirical antibiotic treatment is therefore administered routinely to febrile neutropaenic patients. Currently, either beta-lactam-aminoglycoside combination treatment or beta-lactam monotherapy are recommended. ⋯ We have shown an advantage to broad-spectrum beta-lactam monotherapy over beta-lactam-aminoglycoside combination therapy for febrile neutropaenia. This advantage comprises of 1) a similar, if not better, survival, 2) a significantly lower treatment failure rate, 3) comparable probability for secondary infections and, 4) most importantly, a lower rate of adverse events associated with significant morbidity. Monotherapy can be regarded, therefore, as the standard of care for febrile neutropaenic patients.

Review Meta AnalysisCorticosteroid therapy for nephrotic syndrome in children.
In nephrotic syndrome protein leaks from the blood to the urine through the glomeruli resulting in hypoproteinaemia and generalised oedema. Children with untreated nephrotic syndrome frequently die from infections. The majority of children with nephrotic syndrome respond to corticosteroids. However about 70% of children experience a relapsing course with recurrent episodes of oedema and proteinuria. Corticosteroid usage has reduced the mortality rate in childhood nephrotic syndrome to around 3%, with infection remaining the most important cause of death. However corticosteroids have known adverse effects such as obesity, poor growth, hypertension, diabetes mellitus, osteoporosis and adrenal suppression. The original treatment schedules for childhood nephrotic syndrome were developed in an ad hoc manner. The optimal doses and durations of corticosteroid therapy that are most beneficial and least harmful have not been clarified. ⋯ Children in their first episode of SSNS should be treated for at least three months with an increase in benefit being demonstrated for up to seven months of treatment. In a population with a baseline risk for relapse following the first episode of 60% with two months of prednisone, daily prednisone for four weeks followed by alternate day therapy for six months would be expected to reduce the number of children experiencing a relapse by about 33%. In children who relapse frequently, deflazacort deserves further study.

Review Meta AnalysisAntiplatelet and anticoagulation for patients with prosthetic heart valves.
Patients with prosthetic heart valves are at increased risk for valve thrombosis and arterial thromboembolism. Oral anticoagulation alone, or the addition of antiplatelet drugs, has been used to minimize this risk. An important issue is the effectiveness and safety of the latter strategy. ⋯ Adding antiplatelet therapy, either dipyridamole or low-dose aspirin, to oral anticoagulation decreases the risk of systemic embolism or death among patients with prosthetic heart valves. The risk of major bleeding is increased with antiplatelet therapy. These results apply to patients with mechanical prosthetic valves or those with biological valves and indicators of high risk such as atrial fibrillation or prior thromboembolic events. The effectiveness and safety of low dose aspirin (100 mg daily) appears to be similar to higher dose aspirin and dipyridamole.

While many treatments, including corticosteroid injections in and around the shoulder, are advocated to be of benefit for shoulder pain, few are of proven efficacy. This review of corticosteroid injections for shoulder pain is one in a series of reviews of varying interventions for shoulder disorders. ⋯ Despite many RCTs of corticosteroid injections for shoulder pain, their small sample sizes, variable methodological quality and heterogeneity means that there is little overall evidence to guide treatment. Subacromial corticosteroid injection for rotator cuff disease and intra-articular injection for adhesive capsulitis may be beneficial although their effect may be small and not well-maintained. There is a need for further trials investigating the efficacy of corticosteroid injections for shoulder pain. Other important issues that remain to be clarified include whether the accuracy of needle placement, anatomical site, frequency, dose and type of corticosteroid influences efficacy.
