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. While the majority of children with nephrotic syndrome respond to corticosteroids, 70% experience a relapsing course. Corticosteroid usage has reduced the mortality rate to around 3%, however they have known serious adverse effects. ⋯ 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 For 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 reduce the number of children relapsing by 33%. Deflazacort deserves further study for frequent relapsers.

Review Meta AnalysisLong-acting beta2-agonists versus anti-leukotrienes as add-on therapy to inhaled corticosteroids for chronic asthma.
Patients who continue to experience asthma symptoms despite taking regular inhaled corticosteroids (ICS) represent a management challenge. Leukotriene receptor antagonists (LTRA) and long-acting beta2-agonists (LABA) agents may both be considered as add-on therapy to inhaled corticosteroids (ICS). ⋯ In asthmatic adults inadequately controlled on low doses of inhaled steroids, the addition of LABA is superior to LTRA for preventing exacerbations requiring systemic steroids, and for improving lung function, symptoms, and use of rescue beta2-agonists.

The course of advanced renal cell carcinoma is extremely variable, ranging from spontaneous remission to disease progression refractory to chemotherapy. Immunotherapy has held promise of improved outcomes based on uncontrolled studies and randomized controlled trials generally limited by small size and low power. ⋯ interferon-alfa provides a modest survival benefit compared to other commonly used treatments and should be considered for the control arm of future studies of systemic agents. In fit patients with metastases at diagnosis and minimal symptoms, nephrectomy followed by interferon-alfa gives the best survival strategy for fully validated therapies. The need for more effective specific therapy for this condition is apparent.

Review Meta AnalysisChinese medicinal herbs for acute pancreatitis.
Acute pancreatitis is a relatively common acute abdominal emergency but there is no specific therapy for it. Traditional Chinese medicinal herbs have been used widely for many years in China to treat acute pancreatitis, and several controlled trials have been carried out to investigate their efficacy. ⋯ Some Chinese medicinal herbs may work in acute pancreatitis. However, the evidence is too weak to recommend any single herb. Rigorously designed, randomized, double-blind, placebo-controlled trials are required.

Review Meta AnalysisAntiplatelet and anticoagulant drugs for prevention of restenosis/reocclusion following peripheral endovascular treatment.
Peripheral arterial disease (PAD) is frequently treated by balloon angioplasty. Restenosis/reocclusion of the dilated segments occurs often depending on length of occlusion, lower leg outflow, stage of disease and presence of cardiovascular risk factors. To prevent reocclusion, patients are treated with antithrombotic agents. ⋯ Aspirin 50 to 300 mg started prior to femoropopliteal endovascular treatment appears to be the most effective and is safe. Clopidogrel might be an alternative, but data are lacking. Abciximab might be a useful adjunctive for high risk patients with long segmental femoropopliteal interventions. Low molecular weight heparin seems to be more effective in preventing reocclusion or restenosis than unfractionated heparin.
