Review Meta AnalysisSurgery for thumb (trapeziometacarpal joint) osteoarthritis.
Surgery is used to treat persistent pain and dysfunction at the base of the thumb when conservative management, such as splinting, or medical management, such as oral analgesics, is no longer adequate in reducing disability and pain. This is an update of a Cochrane Review first published in 2005. ⋯ We did not identify any studies that compared surgery to sham surgery and we excluded studies that compared surgery to non-operative treatments. We were unable to demonstrate that any technique confers a benefit over another technique in terms of pain and physical function. Furthermore, the included studies were not of high enough quality to provide conclusive evidence that the compared techniques provided equivalent outcomes.

Review Meta AnalysisPulmonary rehabilitation for chronic obstructive pulmonary disease.
Widespread application of pulmonary rehabilitation (also known as respiratory rehabilitation) in chronic obstructive pulmonary disease (COPD) should be preceded by demonstrable improvements in function (health-related quality of life, functional and maximal exercise capacity) attributable to the programmes. This review updates the review reported in 2006. ⋯ Pulmonary rehabilitation relieves dyspnoea and fatigue, improves emotional function and enhances the sense of control that individuals have over their condition. These improvements are moderately large and clinically significant. Rehabilitation serves as an important component of the management of COPD and is beneficial in improving health-related quality of life and exercise capacity. It is our opinion that additional RCTs comparing pulmonary rehabilitation and conventional care in COPD are not warranted. Future research studies should focus on identifying which components of pulmonary rehabilitation are essential, its ideal length and location, the degree of supervision and intensity of training required and how long treatment effects persist. This endeavour is important in the light of the new subgroup analysis, which showed a difference in treatment effect on the CRQ between hospital-based and community-based programmes but no difference between exercise only and more complex pulmonary rehabilitation programmes.

Chronic deep venous incompetence (DVI) is caused by incompetent vein valves and/or blockage of large-calibre leg veins and causes a range of symptoms including recurrent ulcers, pain and swelling. Most surgeons accept that well-fitted graduated compression stockings (GCS) and local care of wounds serve as adequate treatment for most patients, but sometimes symptoms are not controlled and ulcers recur frequently, or they do not heal despite compliance with conservative measures. In these situations, in the presence of severe venous dysfunction, surgery has been advocated by some vascular surgeons. This is an update of the review first published in 2000. ⋯ No evidence was found for benefit or harm of valvuloplasty in the treatment of patients with DVI secondary to primary valvular incompetence. The individual trials included in this review were small; they used different methods of assessment and overall were of poor quality. They did not include participants with severe DVI. Trials investigating the effects of other surgical procedures on deep veins are needed. Until the findings of such trials become available, the benefit of valvuloplasty remains uncertain.

Review Meta AnalysisArtemisinin-naphthoquine for treating uncomplicated Plasmodium falciparum malaria.
The World Health Organization (WHO) recommends artemisinin-based combination therapy (ACT) for treating people with Plasmodium falciparum malaria. Five combinations are currently recommended, all administered over three days. Artemisinin-naphthoquine is a new combination developed in China, which is being marketed as a one-day treatment. Although shorter treatment courses may improve adherence, the WHO recommends at least three days of the short-acting artemisinin component to eliminate 90% P. falciparum parasites in the bloodstream, before leaving the longer-acting partner drug to clear the remaining parasites. ⋯ The results of these few trials of artemisinin-naphthoquine are promising, but further trials from multiple settings are required to reliably demonstrate the relative efficacy and safety compared to established ACTs. Future trials should be adequately powered to demonstrate non-inferiority, and regimens incorporating three days of the artemisinin component are probably preferable to the one-day regimens.

Review Meta AnalysisChewing gum for postoperative recovery of gastrointestinal function.
Ileus commonly occurs after abdominal surgery, and is associated with complications and increased length of hospital stay (LOHS). Onset of ileus is considered to be multifactorial, and a variety of preventative methods have been investigated. Chewing gum (CG) is hypothesised to reduce postoperative ileus by stimulating early recovery of gastrointestinal (GI) function, through cephalo-vagal stimulation. There is no comprehensive review of this intervention in abdominal surgery. ⋯ This review identified some evidence for the benefit of postoperative CG in improving recovery of GI function. However, the research to date has primarily focussed on CS and CRS, and largely consisted of small, poor quality trials. Many components of the ERAS programme also target ileus, therefore the benefit of CG alongside ERAS may be reduced, as we observed in this review. Therefore larger, better quality RCTS in an ERAS setting in wider surgical disciplines would be needed to improve the evidence base for use of CG after surgery.
