Review Comparative StudyConservative versus interventional management for primary spontaneous pneumothorax in adults.
Primary spontaneous pneumothorax is widely managed according to size with interventional techniques based on practice guidelines. Interventional management is not without complications and observational data suggest conservative management works. The current guidelines are based on expert consensus rather than evidence, and a systematic review may help in identifying evidence for this practice. ⋯ There are no completed randomized controlled trials comparing conservative and interventional management for primary spontaneous pneumothorax in adults. There is a lack of high-quality evidence for current guidelines in management and a need for randomized controlled trials comparing conservative and interventional management for this condition.

Review Meta AnalysisCordyceps sinensis (a traditional Chinese medicine) for treating chronic kidney disease.
Cordyceps sinensis (Cordyceps, Dong Chong Xia Cao), a herbal medicine also known as Chinese caterpillar fungus, is one of the most commonly used ingredients in traditional Chinese medicine for the treatment of people with chronic kidney disease (CKD). ⋯ We found that Cordyceps preparation, as an adjuvant therapy to conventional medicine, showed potential promise to decrease serum creatinine, increase creatine clearance, reduce proteinuria and alleviate CKD-associated complications, such as increased haemoglobin and serum albumin. However, definitive conclusions could not be made because of the low quality of evidence.

ReviewEphedrine for myasthenia gravis, neonatal myasthenia and the congenital myasthenic syndromes.
Myasthenia is a condition in which neuromuscular transmission is affected by antibodies against neuromuscular junction components (autoimmune myasthenia gravis, MG; and neonatal myasthenia gravis, NMG) or by defects in genes for neuromuscular junction proteins (congenital myasthenic syndromes, CMSs). Clinically, some individuals seem to benefit from treatment with ephedrine, but its effects and adverse effects have not been systematically evaluated. ⋯ There was no evidence available from RCTs or quasi-RCTs, but some observations from non-randomised studies are available. There is a need for more evidence from suitable forms of prospective RCTs, such as series of n-of-one RCTs, that use appropriate and validated outcome measures.

Review Meta AnalysisGraduated compression stockings for prevention of deep vein thrombosis.
One of the settings where deep vein thrombosis (DVT) in the lower limb and pelvic veins occurs is in hospital with prolonged immobilisation of patients for various surgical and medical illnesses. Using graduated compression stockings (GCS) in these patients has been proposed to decrease the risk of DVT. This is an update of a Cochrane review first published in 2000 and updated in 2010. ⋯ GCS are effective in diminishing the risk of DVT in hospitalised patients, with strong evidence favouring their use in general and orthopaedic surgery. However, evidence for their effectiveness in medical patients is limited to one trial.

Review Meta AnalysisMechanical devices for urinary incontinence in women.
Incontinence can have a devastating effect on the lives of sufferers with significant economic implications. Non-surgical treatments such as pelvic floor muscle training and the use of mechanical devices are usually the first line of management, particularly when a woman does not want surgery or when she is considered unfit for surgery. Mechanical devices are inexpensive and do not compromise future surgical treatment. ⋯ The place of mechanical devices in the management of urinary incontinence remains in question. Currently there is little evidence from controlled trials on which to judge whether their use is better than no treatment and large well-conducted trials are required for clarification. There was also insufficient evidence in favour of one device over another and little evidence to compare mechanical devices with other forms of treatment.
