Review Meta AnalysisNeuromuscular electrical stimulation for muscle weakness in adults with advanced disease.
Patients with progressive diseases often experience muscle weakness, which impacts adversely on levels of independence and quality of life. In those who are unable or unwilling to undertake traditional forms of exercise, neuromuscular electrical stimulation (NMES) may provide an alternative method of enhancing leg muscle strength. Programmes appear to be well tolerated and have led to improvements in muscle function, exercise capacity and quality of life. However, estimates regarding the effectiveness of NMES from individual studies lack power and precision. ⋯ NMES appears an effective means of improving muscle weakness in adults with progressive diseases such as COPD, chronic heart failure and cancer. Further research is required to clarify its place in clinical practice, by determining the optimal parameters for a NMES programme, the patients most likely to benefit, and its impact on morbidity and service use.

Review Meta Analysis Comparative StudySurgical versus non-surgical treatment for thoracolumbar burst fractures without neurological deficit.
Spinal burst fractures result from the failure of both the anterior and the middle columns of the spine under axial compression loads. Conservative management is through bed rest and immobilisation once the acute symptoms have settled. Surgical treatment involves either anterior or posterior stabilisation of the fracture, sometimes with decompression involving the removal of bone fragments that have intruded into the vertebral canal. This is an update of a review first published in 2006. ⋯ The contradictory evidence provided by two small and potentially biased randomised controlled trials is insufficient to conclude whether surgical or non-surgical treatment yields superior pain and functional outcomes for people with thoracolumbar burst fractures without neurological deficit. It is likely, however, that surgery is associated with more early complications and the need for subsequent surgery, as well as greater initial healthcare costs.

Review Meta AnalysisTiotropium versus ipratropium bromide for chronic obstructive pulmonary disease.
Tiotropium and ipratropium bromide are both recognised treatments in the management of people with stable chronic obstructive pulmonary disease (COPD). There are new studies which have compared tiotropium with ipratropium bromide, making an update necessary. ⋯ This review shows that tiotropium treatment, when compared with ipratropium bromide, was associated with improved lung function, fewer hospital admissions (including those for exacerbations of COPD), fewer exacerbations of COPD and improved quality of life. There were both fewer serious adverse events and disease specific events in the tiotropium group, but no significant difference in deaths with ipratropium bromide when compared to tiotropium. Thus, tiotropium appears to be a reasonable choice (instead of ipratropium bromide) for patients with stable COPD, as proposed in guidelines. We would advise some caution with tiotropium via the Respimat inhaler and suggest waiting for further information from an ongoing head-to-head trial comparing mortality in relation to tiotropium delivery devices and doses.

Review Meta AnalysisCalcium antagonists as an add-on therapy for drug-resistant epilepsy.
This is an updated version of the original Cochrane review published in The Cochrane Library 2001, Issue 4.Nearly a third of people with epilepsy do not have their seizures controlled with current treatments. Continuous attempts have been made to find new antiepileptic drugs based on increasing knowledge of the cellular and molecular biology involved in the genesis of epilepsy and seizures. Therefore, calcium antagonists that can alter the effects of calcium on brain cells have been investigated for their effect on epileptic seizures. ⋯ Flunarizine may have a weak effect on seizure frequency but had a significant withdrawal rate, probably due to adverse effects, and should not be recommended for use as an add-on treatment. Similarly, there is no convincing evidence to support the use of nifedipine or nimodipine as add-on treatments for epilepsy.

Review Meta AnalysisUse of plastic adhesive drapes during surgery for preventing surgical site infection.
Surgical site infection has been estimated to occur in about 15% of clean surgery and 30% of contaminated surgery cases. Using plastic adhesive drapes to protect the wound from organisms that may be present on the surrounding skin during surgery is one strategy used to prevent surgical site infection. Results from non-randomised studies have produced conflicting results about the efficacy of this approach, but no systematic review has been conducted to date to guide clinical practice. ⋯ There was no evidence from the seven trials that plastic adhesive drapes reduce surgical site infection rates, and some evidence that they increase infection rates. Further trials may be justified, using blinded outcome assessment to examine the effect of adhesive drapes on surgical site infection, based on different wound classifications.
