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 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 AnalysisHome versus center based physical activity programs in older adults.
Physical inactivity is a leading cause of preventable death and morbidity in developed countries. In addition physical activity can potentially be an effective treatment for various medical conditions (e.g. cardiovascular disease, osteoarthritis). Many types of physical activity programs exist ranging from simple home exercise programs to intense highly supervised hospital (center) based programs. ⋯ In the short-term, center based programs are superior to home based programs in patients with PVD. There is a high possibility of a training effect however as the center based groups were trained primarily on treadmills (and the home based were not) and the outcome measures were treadmill based. There is conflicting evidence which is better in patients with COPD. Home based programs appear to be superior to center based programs in terms of the adherence to exercise (especially in the long-term).

Review Meta AnalysisInterventions for replacing missing teeth: different types of dental implants.
Dental implants are available in different materials, shapes and with different surface characteristics. In particular, numerous implant surface modifications have been developed for enhancing clinical performances. ⋯ Based on the available results of RCTs, there is limited evidence showing that implants with relatively smooth (turned) surfaces are less prone to loose bone due to chronic infection (perimplantitis) than implants with rougher surfaces. On the other hand, there is no evidence showing that any particular type of dental implant has superior long-term success. These findings are based on a few RCTs, often at high risk of bias, with few participants and relatively short follow-up periods. More RCTs should be conducted, with follow up of at least 5 years including a sufficient number of patients to detect a true difference if any exists. Such trials should be reported according to the CONSORT recommendations (http://www.consort-statement.org/).

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.
