ReviewElectrical stimulation for preventing and treating post-stroke shoulder pain.
Shoulder pain after stroke is common and disabling. The optimal management is uncertain, but electrical stimulation (ES) is often used to treat and prevent pain. ⋯ The evidence from randomised controlled trials so far does not confirm or refute that ES around the shoulder after stroke influences reports of pain, but there do appear to be benefits for passive humeral lateral rotation. A possible mechanism is through the reduction of glenohumeral subluxation. Further studies are required.

To estimate the short-term efficacy and toxicity of methotrexate (MTX) for the treatment of rheumatoid arthritis (RA). ⋯ Twenty-two percent of people on MTX withdrew due to adverse effects compared to seven percent of the placebo group. MTX has a substantial clinically and statistically significant benefit in the short term treatment of patients with RA.

ReviewEndotracheal intubation at birth for preventing morbidity and mortality in vigorous, meconium-stained infants born at term.
On the basis of evidence from non-randomised studies, it has been recommended that all babies born through thick meconium should have their tracheas intubated so that suctioning of their airways can be performed. The aim is to reduce the incidence and severity of meconium aspiration syndrome. However, for term babies who are vigorous at birth endotracheal intubation may be both difficult and unnecessary. ⋯ Routine endotracheal intubation at birth in vigorous term meconium-stained babies has not been shown to be superior to routine resuscitation including oro-pharyngeal suction. This procedure cannot be recommended for vigorous infants until more research is available.

Currently hydergine is used almost exclusively for treating patients with either dementia, or 'age-related' cognitive symptoms. Since the early eighties there have been over a dozen more clinical trials, yet hydergine's efficacy remains uncertain. Although previous reviews offer generally favorable support for hydergine's efficacy, they were, however, limited by a bias with respect to the particular clinical studies chosen (eg, the inclusion of case reports, and uncontrolled trials), and by authors' impressionistic assessments of results. Not surprisingly, there has been a lack of consensus among reviewers with regard to the efficacy of hydergine. In 1994, a meta-analysis was published by the present reviewers who reported that overall, hydergine was more effective than placebo. However they also observed that the statistical evidence for efficacy in 'possible or probable Alzheimer's disease' patients was so modest that one additional statistically non-significant trial would have reduced the results to non significance. ⋯ As in an earlier systematic review, we found hydergine to show significant treatment effects when assessed by either global ratings or comprehensive rating scales (based here on a smaller set of trials than in the earlier published systematic review because trials were required to have data that could conform with MetaView, the Cochrane Collaboration statistics software). The small number of trials available for analysis, however, limited the ability of subgroup analyses to identify statistically significant modera

ReviewImproving health professionals' management and the organisation of care for overweight and obese people.
Obesity is increasing throughout the industrialised world. If left unchecked it will have major implications for both population health and costs to health services. Health professionals have a key role to play in tackling the obesity problem, but little is known about how they may be encouraged to work more effectively with overweight and obese people. ⋯ At present, decisions about improving provision of services must be based on the evidence of patient interventions and good clinical judgement. Further research is needed to identify cost effective strategies for improving the management of obesity.
