ReviewCommunication skills training for health care professionals working with cancer patients, their families and/or carers.
Research suggests communication skills do not reliably improve with experience and considerable effort is dedicated to courses improving communication skills for health professionals. The evaluation of such courses is of importance to enable evidence-based teaching and practice. ⋯ The training programmes assessed by these trials appear to be effective in improving cancer care professionals communication skills. It is not known whether the training would be effective if taught by other educators, nor has any trial compared the efficacy of both programmes.

ReviewMale circumcision for prevention of heterosexual acquisition of HIV in men.
The findings from observational studies, reviews and meta-analyses, supported by biological theories, that circumcised men appear less likely to acquire human immunodeficiency virus (HIV) has contributed to the recent ground swell of support for considering male circumcision as a strategy for preventing sexually acquired infection. We sought to elucidate and appraise the global evidence from published and unpublished studies that circumcision can be used as an intervention to prevent HIV infection. ⋯ We found insufficient evidence to support an interventional effect of male circumcision on HIV acquisition in heterosexual men. The results from existing observational studies show a strong epidemiological association between male circumcision and prevention of HIV, especially among high-risk groups. However, observational studies are inherently limited by confounding which is unlikely to be fully adjusted for. In the light of forthcoming results from RCTs, the value of IPD analysis of the included studies is doubtful. The results of these trials will need to be carefully considered before circumcision is implemented as a public health intervention for prevention of sexually transmitted HIV.

Current treatment of sleep apnoea in children consists of largely surgical based treatments. Adenotonsillectomy is the most commonly used intervention to treat sleep apnoea in children. ⋯ At present there is still debate as to the polysomnographic criteria required to diagnose significant obstructive sleep apnoea in children. Also the natural history of the condition has not been fully delineated. There is an absence of randomised controlled trials investigating the efficacy of treatment of obstructive sleep apnoea with adenotonsillectomy in children and, therefore, further research is required before recommendations for the treatment of obstructive sleep apnoea in children can be formulated.

The tremor of Parkinson's disease can cause considerable disability for the individual concerned. Traditional antiparkinsonian therapies such as levodopa have only a minor effect on tremor. Beta-blockers are used to attenuate other forms of tremor such as Essential Tremor or the tremor associated with anxiety. It is thought that beta-blockers may be of use in controlling the tremor of Parkinson's disease. ⋯ In view of this lack of evidence, it is impossible to determine whether beta-blocker therapy is effective and safe for the treatment of tremor in Parkinson's disease. The high frequency of bradycardia in one trial raises some concerns about the prescription of beta-blockers to normotensive elderly patients but the study was too small for the true degree of risk to be calculated.

ReviewTreadmill training and body weight support for walking after stroke.
Treadmill training, with some body weight supported using a harness, is a method of treating walking after stroke. Systematic review is required to assess the cost, effectiveness and acceptance of this treatment. ⋯ Overall, no statistically significant effect of treadmill training and body weight support was detected. However, among people who could walk independently, treadmill training with body weight support appeared to be more effective than other interventions at improving walking speed, but this conclusion was not robust.
