The single most important risk factor for postpartum maternal infection is Cesarean delivery. ⋯ The reduction of endometritis by two thirds to three quarters justifies a policy of administering prophylactic antibiotics to women undergoing elective or non-elective Cesarean section.

ReviewAntioxidant vitamin and mineral supplements for age-related macular degeneration.
It has been proposed that antioxidants may prevent cellular damage in the retina by reacting with free radicals produced in the process of light absorption. ⋯ The question as to whether people with age-related macular degeneration should take antioxidant vitamin or mineral supplements to prevent progression of the disease has not been answered by research to date. The results of ongoing trials are awaited.

ReviewInterventions for promoting adherence to tuberculosis management.
Up to half the people with tuberculosis do not complete their treatment. Strategies to improve adherence to treatment can be targeted at the person with the disease or at health workers. ⋯ We have found evidence of benefit for a number of specific interventions to improve adherence to anti-tuberculous therapy and completion of diagnostic protocols. These should be implemented by health care providers where appropriate to local circumstances. Future studies in low income countries are a priority and should measure adherence as well as clinical outcomes.

Review Comparative StudyRisperidone versus typical antipsychotic medication for schizophrenia.
The 'conventional' neuroleptic drugs, such as haloperidol and chlorpromazine, are frequently used as the first line treatment for people with schizophrenia. However, about 5-25% of these people show poor response to these treatments and side effects often makes compliance with the 'older generation' of drug treatment problematic. Although the efficacy of these medications with respect to 'positive' symptoms is well described, little evidence exists that 'conventional' antipsychotic treatment has any effect on the 'negative' symptoms of schizophrenia. Risperidone is one of the 'new generation' neuroleptic compounds. As well as its reputed tendency to cause fewer movement disorders it is claimed that risperidone may improve negative symptoms. ⋯ Little can be concluded about the long term effects of risperidone and generalising results beyond a comparison with haloperidol would be imprudent. Risperidone may be more acceptable to those with schizophrenia and have marginal benefits in terms of limited clinical improvement and side

Review Meta AnalysisPharmacological interventions for non-ulcer dyspepsia.
The commonest cause of upper gastrointestinal symptoms is non-ulcer dyspepsia (NUD) and yet the pathophysiology of this condition has been poorly characterised and the optimum treatment is uncertain. It is estimated that pound450 million is spent on dyspepsia drugs in the UK each year. ⋯ There is some evidence that anti-secretory therapy may be effective in NUD. The trials evaluating prokinetic therapy are difficult to interpret as the meta-analysis result could have been due to publication bias. Further research using prokinetics and anti-secretory therapy is required before any firm conclusions can be reached. The effect of these drugs is likely to be small and many patients will need to take them on a long-term basis so the therapies assessed need to be inexpensive and well tolerated.
