Review Meta AnalysisLocal versus general anaesthesia for carotid endarterectomy.
Carotid endarterectomy reduces the risk of stroke in people with recently symptomatic, severe carotid artery stenosis. However, there are significant perioperative risks which may be lessened by performing the operation under local rather than general anaesthetic. This is an update of a Cochrane review first published in 1996, and previously updated in 2004. ⋯ There is insufficient evidence from randomised trials comparing carotid endarterectomy performed under local and general anaesthetic. Non-randomised studies suggest potential benefits with the use of local anaesthetic, but these studies may be biased.

Review Meta AnalysisBlood pressure lowering efficacy of angiotensin receptor blockers for primary hypertension.
Angiotensin receptor blockers (ARBs) are widely prescribed for hypertension so it is essential to determine and compare their effects on blood pressure (BP), heart rate and withdrawals due to adverse effects (WDAE). ⋯ The evidence from this review suggests that there are no clinically meaningful BP lowering differences between available ARBs. The BP lowering effect of ARBs is modest and similar to ACE inhibitors as a class; the magnitude of average trough BP lowering for ARBs at maximum recommended doses and above is -8/-5 mmHg. Furthermore, 60 to 70% of this trough BP lowering effect occurs with recommended starting doses. The review did not provide a good estimate of the incidence of harms associated with ARBs because of the short duration of the trials and the lack of reporting of adverse effects in many of the trials.

Review Meta AnalysisOnce or twice daily versus three times daily amoxicillin with or without clavulanate for the treatment of acute otitis media.
Acute otitis media (AOM) is a common problem in children, for which the antibiotic amoxicillin, with or without clavulanate, is frequently prescribed. ⋯ This review showed insufficient evidence to judge whether once or twice daily doses of amoxicillin, with or without clavulanate, were comparable with three or four daily doses for the treatment of AOM. The evidence appears to be biased and therefore no firm conclusions can be drawn.

Review Meta Analysis Comparative StudySurgical versus non-surgical treatment for carpal tunnel syndrome.
Carpal tunnel syndrome results from entrapment of the median nerve in the wrist. Common symptoms are tingling, numbness, and pain in the hand that may radiate to the forearm or shoulder. Most symptomatic cases are treated non-surgically. ⋯ Surgical treatment of carpal tunnel syndrome relieves symptoms significantly better than splinting. Further research is needed to discover whether this conclusion applies to people with mild symptoms and whether surgical treatment is better than steroid injection.

Review Meta AnalysisInterval debulking surgery for advanced epithelial ovarian cancer.
Primary debulking surgery, a crucial step in the management of epithelial ovarian cancer, is not always possible in patients with advanced stage disease (stage III to IV). In some circumstances, surgery may have been attempted but generally does not yield good results with residual tumour masses > 1 to 2 cm (so called suboptimal surgery). Induction or neoadjuvant chemotherapy followed by interval debulking surgery (IDS) may have an alternative role in this setting. However, the advantage of IDS compared to conventional methods is still a controversial issue. ⋯ No conclusive evidence was found to determine whether IDS between cycles of chemotherapy would improve or decrease the survival of women with advanced ovarian cancer, compared with conventional treatment of primary surgery followed by adjuvant chemotherapy. IDS appeared to yield benefit only in the patients whose primary surgery was not performed by gynecologic oncologists. Data on QOL and adverse events were inconclusive.
