ReviewAntihypertensive therapy for preventing cardiovascular complications in people with diabetes mellitus.
To assess the effect of intervention, both pharmacological and non-parmacological, to reduce blood pressure in people with diabetes mellitus on all cause mortality, specific causes of death, including cardiovascular disease, stroke, ischaemic heart disease and renal disease, morbidity associated with macro- and microvascular complications of diabetes mellitus and also side effects of the interventions and their influence on quality of life and well being. ⋯ Primary intervention trials indicated a treatment benefit for CVD, but not for total mortality in people with diabetes. For both short- and long-term secondary prevention, the present meta-analysis indicated a benefit for total mortality in diabetic subjects. However lack of information on CVD outcomes probably reduced the power of the meta-analysis to detect any corresponding benefit for this end-point. This, along with the fact that all published data of randomised control trials of anti-hypertensive therapy in diabetes for all cause mortailty and CVD outcomes are taken from the hypertension trials not specific to diabetes, underlines the need for further high quality trials examining the effects of blood pressure lowering interventions in people with diabetes.

ReviewEpidural versus non-epidural analgesia for pain relief in labour.
Epidural analgesia is effective in reducing labour pain, but the possible adverse effects are not clear. ⋯ Epidural analgesia appears to be very effective in reducing pain during labour, although there appear to be some potentially adverse effects. Further research is needed to investigate adverse effects and to evaluate the different techniques used in epidural analgesia.

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.
