ReviewPerioperative local anaesthesia for reducing pain following tonsillectomy.
Pain relief after tonsillectomy is an important part of post-operative management. Sometimes local anaesthetics are administed to the tonsillar region, but their effectiveness in relieving pain has not been formally assessed. ⋯ There is no evidence that the use of perioperative local anaesthetic in patients undergoing tonsillectomy improves post-operative pain control. The trials identified were of small size and several involved the perioperative co-administration of intravenous opiates which may have masked any beneficial effect of the local anaesthetic. Further randomised controlled trials are necessary.

When pregnant women near term lie in the supine position the uterus can compress the inferior vena cava, interfering with venous return to the heart. This can result in hypotension, reduced placental perfusion and decreased fetal oxygenation. ⋯ There is not enough evidence from these trials to evaluate use of lateral tilt during caesarean section.

Review Meta AnalysisExtramedullary fixation implants for extracapsular hip fractures.
Extramedullary fixation of hip fractures refers to the application of a plate and screws to the lateral side of the proximal femur. ⋯ The fixed nail plate has higher risks of implant breakage and fixation failure than the SHS. Though insufficient evidence on other outcomes is available from randomised trials, the increased fixation failure rate is a major consideration and thus the SHS appears preferable. Insufficient information is available to draw firm conclusions of the clinical significance of differences between the SHS and either the RAB plate, the Pugh nail or the Medoff plate.

ReviewMultidisciplinary biopsychosocial rehabilitation for subacute low back pain among working age adults.
Multidisciplinary biopsychosocial rehabilitation programs are widely applied for chronic low back pain patients. The biopsychosocial approach for low back pain could also be considered to prevent chronicity by carrying out the rehabilitation if the acute pain is prolonged. Nevertheless multidisciplinary treatment programmes are often laborious and long processes and require good collaboration between the patient, the rehabilitation team and the work place. By workplace visits and close relationship with occupational health care one might expect results in terms of patients working ability. ⋯ We conclude that there is moderate evidence of positive effectiveness of multidisciplinary rehabilitation for subacute low back pain and workplace visit increases the effectiveness. But because this evidence is based on the trials that had some methodological shortcomings and several expensive multidisciplinary rehabilitation programmes are commonly used for common subacute low back problems, there is an obvious need for high quality trials in this field.

ReviewNocturnal mechanical ventilation for chronic hypoventilation in patients with neuromuscular and chest wall disorders.
Chronic alveolar hypoventilation is a common complication of many neuromuscular and chest wall disorders. Long term nocturnal mechanical ventilation is used to treat an increasing number of patients. ⋯ Current evidence about the therapeutic benefit of mechanical ventilation is weak, but consistent, suggesting alleviation of the symptoms of chronic hypoventilation in the short term, and in two small studies survival was prolonged. Mechanical ventilation should be offered as a therapeutic option to patients with chronic hypoventilation due to neuromuscular diseases. Further larger randomized trials are needed to confirm long term beneficial effects of nocturnal mechanical ventilation on quality of life, morbidity and mortality, to assess its cost-benefit ratio, and to compare the different types and modes of ventilation.
