ReviewNewer atypical antipsychotic medication versus clozapine for schizophrenia.
Clozapine is an atypical antipsychotic drug, which is claimed to have superior efficacy and to cause fewer movement disorders. However, clozapine carries a significant risk of serious blood disorders. Newer atypical antipsychotics are safer alternatives that might share the benefits of clozapine. It is thus of interest to compare the effectiveness of newer atypical antipsychotics with the effectiveness of clozapine. ⋯ The equal effectiveness and tolerability of new atypical drugs in comparison with clozapine is not yet demonstrated. Lack of statistical power to determine the comparative efficacy and effectiveness of newer atypical drugs makes it difficult to judge whether newer drugs are more effective, less effective or equivalent. Trials of sufficient power, with longer duration, measuring clinically important outcomes, are needed to assess the true comparative clinical effectiveness, tolerability and cost effectiveness of newer drugs in relation to clozapine.

Amodiaquine has been widely used to treat malaria. Due to reports of fatal adverse drug reactions, discontinuation or modification of its use has been suggested. ⋯ There is some evidence to support the continued use of amodiaquine in the treatment of uncomplicated malaria, although drug resistance should be considered. Monitoring for toxicity should also continue.

ReviewCaregivers' use of strict criteria for diagnosing active labour in term pregnancy.
Application of specific criteria for diagnosis of active labour as part of a labour assessment program aims to differentiate more accurately between latent and active phases of labour. ⋯ Early labour assessment (which includes use of specific criteria for diagnosis of active labour) may have some positive outcomes for women at term pregnancy.

Patients with isolated supratentorial brain tumours, presumed to be primary on imaging, have two surgical management options - biopsy or resection. Surgical opinions appear to be equally divided when considering the relative risks and benefits of these two procedures. ⋯ Given that no qualifying studies were identified and because this is an important issue, both in terms of patient risk and benefit and health economics, the author feels it important to conduct a randomised controlled trial in this subject.

Traveller's diarrhoea is a syndrome frequently encountered in persons crossing an international boundary. Diarrhoea can lead to significant discomfort and interference with travel plans. Bacterial pathogens are a frequent cause of this syndrome. Several antibiotics have been tested for efficacy in reducing the duration and severity of the illness. ⋯ Antibiotic treatment is associated with shorter duration of diarrhoea but higher incidence of side-effects. Trials generally do not report duration of post-treatment diarrhoea using time-to-event analyses, and should do.
