ReviewAmplification with hearing aids for patients with tinnitus and co-existing hearing loss.
Tinnitus is described as the perception of sound or noise in the absence of real acoustic stimulation. In the current absence of a cure for tinnitus, clinical management typically focuses on reducing the effects of co-morbid symptoms such as distress or hearing loss. Hearing loss is commonly co-morbid with tinnitus and so logic implies that amplification of external sounds by hearing aids will reduce perception of the tinnitus sound and the distress associated with it. ⋯ The current evidence base for hearing aid prescription for tinnitus is limited. To be useful, future studies should make appropriate use of blinding and be consistent in their use of outcome measures. Whilst hearing aids are sometimes prescribed as part of tinnitus management, there is currently no evidence to support or refute their use as a more routine intervention for tinnitus.

Review Meta AnalysisKinship care for the safety, permanency, and well-being of children removed from the home for maltreatment.
Every year a large number of children around the world are removed from their homes because they are maltreated. Child welfare agencies are responsible for placing these children in out-of-home settings that will facilitate their safety, permanency, and well-being.However, children in out-of-home placements typically display more educational, behavioural, and psychological problems than do their peers, although it is unclear whether this results from the placement itself, the maltreatment that precipitated it, or inadequacies in the child welfare system. ⋯ This review supports the practice of treating kinship care as a viable out-of-home placement option for children removed from the home for maltreatment. However, this conclusion is tempered by the pronounced methodological and design weaknesses of the included studies.

Carpal tunnel syndrome (CTS) is the most common compressive neuropathy of the upper extremity. It is caused by increased pressure on the median nerve between the transverse carpal ligament and the carpal bones. Surgical treatment consists of the release of the nerve by cutting the transverse carpal ligament. This can be done either with an open approach or endoscopically. ⋯ In this review, with support from low quality evidence only, OCTR and ECTR for carpal tunnel release are about as effective as each other in relieving symptoms and improving functional status, although there may be a functionally significant benefit of ECTR over OCTR in improvement in grip strength. ECTR appears to be associated with fewer minor complications compared to OCTR, but we found no difference in the rates of major complications. Return to work is faster after endoscopic release, by eight days on average. Conclusions from this review are limited by the high risk of bias, statistical imprecision and inconsistency in the included studies.

Review Meta AnalysisOvulation triggers in anovulatory women undergoing ovulation induction.
Anovulation is a common cause of infertility. Drugs used to treat anovulation include selective oestrogen receptor modulators, aromatase inhibitors and gonadotrophins. Ovulation triggers are used with these drugs, as a surrogate for the hormonal surge seen in spontaneous menstrual cycles, to control the timing of ovulation and the timing of sexual intercourse. Ovulation triggers given without reliable evidence of oocyte maturity could be inappropriately timed; they increase costs, and the need to time intercourse precisely after the ovulation trigger is given adds to psychological stress.This is an update of a Cochrane review first published in Issue 3, 2008, of the Cochrane Database of Systematic Reviews. ⋯ Evidence is inadequate to recommend or refute the use of urinary hCG as an ovulation trigger in anovulatory women treated with clomiphene citrate. We found no trials evaluating the use of ovulation triggers in anovulatory women treated with other ovulation-inducing agents.

Review Meta AnalysisProgestational agents for treating threatened or established preterm labour.
Prematurity is not only the leading cause of perinatal morbidity and mortality but is associated with long-term impairment. Studies of various tocolytic agents have shown mixed results with little effect in improving pregnancy duration and insufficient data to confirm a definite beneficial effect on neonatal morbidity or mortality. Progesterone is known to have an inhibitory effect on uterine contractility and is thought to play a key role in the maintenance of pregnancy until term. ⋯ There is insufficient evidence to advocate progestational agents as a tocolytic for women presenting with preterm labour.
