Nonabsorbable disaccharides (lactulose or lactitol) are considered the treatment of choice for hepatic encephalopathy. ⋯ This systematic review questions the beneficial effects of nonabsorbable disaccharides and highlights that there is insufficient high-quality evidence to support this treatment. We found that antibiotics appeared to be superior to nonabsorbable disaccharides in improving hepatic encephalopathy, but it is unclear whether this difference in treatment effect is clinically important to patients. Nonabsorbable disaccharides should not serve as comparator in randomised trials on hepatic encephalopathy.

ReviewAnti-leukotriene agents compared to inhaled corticosteroids in the management of recurrent and/or chronic asthma in adults and children.
Anti-leukotrienes agents are currently being studied as alternative first line agents to inhaled corticosteroids in mild to moderate chronic asthma. ⋯ Inhaled steroids at a dose of 400 mcg/day of beclomethasone or equivalent are more effective than anti-leukotriene agents given in the usual licensed doses. The exact dose-equivalence of anti-leukotriene agents in mcg of ICS remains to be determined. Inhaled glucocorticoids should remain the first line monotherapy for persistent asthma.

Studies have reported high tumour response rates for platinum-containing regimens in the treatment of women with metastatic breast cancer. ⋯ In view of the significant excess toxicity, lack of progression or survival benefit and the availability of less toxic active agents it is difficult to justify the use of platinum-containing regimens, particularly as first line treatment for women with metastatic breast cancer in routine clinical practice. Ongoing trials are examining the possibility of synergy between platins and trastuzamab, a monoclonal antibody treatment. No randomised trials containing oxalplatin were identified for the present review.

Acute otitis media (AOM) is one of the most common diseases in early infancy and childhood. Long term effects of recurrent episodes of otitis media, rapid emergence of drug resistant bacteria associated with AOM worldwide and huge estimated direct and indirect annual costs associated with otitis media have emphasized the need for an effective vaccination program to prevent episodes of AOM. ⋯ Based on the currently available results of the effectiveness of pneumococcal vaccination for the prevention of AOM, a large scale use of pneumococcal polysaccharide and conjugate vaccination for this specific indication is not yet recommended. So far, pneumococcal conjugate vaccinations are not indicated in the management of recurrent AOM in toddlers and older children. The results of currently ongoing trials of 9- and 11-valent conjugate vaccines should provide more information as to whether pneumococcal vaccines are more effective in specific high-risk populations like infants and older children with recurrent AOM or immunodeficiency.

Herbal medicines are being used for treating viral diseases including viral myocarditis, and many controlled trials have been done to investigate their efficacy. ⋯ Some herbal medicines may have anti-arrhythmia effect in suspected viral myocarditis. However, interpretation of these findings should be careful due to the low methodological quality, small sample size, and limited number of trials on individual herbs. In the light of the findings, some herbal medicines deserve further examination in rigorous trials.
