Review Meta AnalysisThird generation cephalosporins versus conventional antibiotics for treating acute bacterial meningitis.
Antibiotic therapy for suspected acute bacterial meningitis (ABM) needs to be started immediately, even before the results of cerebrospinal fluid (CSF) culture and antibiotic sensitivity are available. Immediate commencement of effective treatment using the intravenous route may reduce death and disability. Although bacterial meningitis guidelines advise the use of third generation cephalosporins, these drugs are often not available in hospitals in low income countries. ⋯ The review shows no clinically important difference between ceftriaxone or cefotaxime and conventional antibiotics. In situations where availability or affordability is an issue, third generation cephalosporins, ampicillin-chloramphenicol combination, or chloramphenicol alone may be used as alternatives. The antimicrobial resistance pattern against various antibiotics needs to be closely monitored in low to middle income countries as well as high income countries.

Review Meta AnalysisInterventions for preventing non-melanoma skin cancers in high-risk groups.
Some groups of people have a greater risk of developing common non-melanoma skin cancers (NMSC). ⋯ Some preventative treatments may benefit people at high risk of developing NMSC, but the ability to draw firm conclusions is limited by small numbers of trials, often with one trial per intervention or with inconsistent results between studies.

Review Meta AnalysisEducational outreach visits: effects on professional practice and health care outcomes.
Educational outreach visits (EOVs) have been identified as an intervention that may improve the practice of healthcare professionals. This type of face-to-face visit has been referred to as university-based educational detailing, academic detailing, and educational visiting. ⋯ EOVs alone or when combined with other interventions have effects on prescribing that are relatively consistent and small, but potentially important. Their effects on other types of professional performance vary from small to modest improvements, and it is not possible from this review to explain that variation.

Review Meta AnalysisCorticosteroid therapy for nephrotic syndrome in children.
In nephrotic syndrome (NS) protein leaks from the blood to the urine through the glomeruli resulting in hypoproteinaemia and generalised oedema. While the majority of children with NS respond to corticosteroids, 70% experience a relapsing course. Corticosteroids have reduced the mortality rate to around 3%. However corticosteroids have well recognised potentially serious adverse effects such as obesity, poor growth, hypertension, diabetes mellitus and osteoporosis. ⋯ Children in their first episode of SSNS should be treated for at least three months with an increase in benefit for up to seven months of treatment. For a baseline risk for relapse following the first episode of 60% with two months of therapy, daily prednisone or prednisolone given for four weeks followed by alternate-day therapy for six months would reduce the number of children relapsing by 33%.

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 performance. ⋯ Based on the available results of RCTs, there is limited evidence showing that implants with relatively smooth (turned) surfaces are less prone to lose 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. Such trials should be reported according to the CONSORT recommendations (http://www.consort-statement.org/).
