ReviewNon-surgical treatment (other than steroid injection) for carpal tunnel syndrome.
Non-surgical treatment for carpal tunnel syndrome is frequently offered to those with mild to moderate symptoms. The effectiveness and duration of benefit from non-surgical treatment for carpal tunnel syndrome remain unknown. ⋯ Current evidence shows significant short-term benefit from oral steroids, splinting, ultrasound, yoga and carpal bone mobilisation. Other non-surgical treatments do not produce significant benefit. More trials are needed to compare treatments and ascertain the duration of benefit.

Review Meta AnalysisAnticholinergic therapy for chronic asthma in children over two years of age.
In the intrinsic system of controlling airway calibre, the cholinergic (muscarinic) sympathetic nervous system has an important role. Anticholinergic, anti muscarinic bronchodilators such as ipratropium bromide are frequently used in the management of childhood airway disease. In asthma, ipratropium is a less potent bronchodilator than beta-2 adrenergic agents but it is known to be a useful adjunct to other therapies, particularly in status asthmaticus. What remains unclear is the role of anticholinergic drugs in the maintenance treatment of chronic asthma. ⋯ The present review summarises the best evidence available to date. Although there were some small beneficial findings in favour of anticholinergic therapy, there is insufficient data to support the use of anticholinergic drugs in the maintenance treatment of chronic asthma in children.

Review Meta AnalysisEarly versus deferred treatment for early stage multiple myeloma.
Early stage multiple myeloma (MM) represents about 20% of MM. Most of the patients are asymptomatic. Thus, it is far less dramatic than advanced disease and may require different treatment strategies. For these patients, it is not clear whether it is better to start chemotherapy right after the diagnosis or to delay the treatment until symptoms become obvious as the disease progresses. ⋯ Early treatment of early stage multiple myeloma inhibits disease progression, and may reduce vertebral compression. However, early treatment may increase the risk of acute leukemia. However, the data on vertebral compression and leukaemic transformation may not be interpretable due to very small numbers. Based on the current evidence, mortality and response rate are not significantly affected by introducing early treatment in the progression of myeloma. However, it is quite possible that the lack of beneficial effects of early intervention in myeloma is a false negative result due to the paucity of the existing evidence. In addition, data on quality of life and toxicity were sparsely reported adding to additional difficulties about management decisions in early stage myeloma.

Review Meta AnalysisLow dosage tricyclic antidepressants for depression.
Tricyclic antidepressants are still extensively prescribed worldwide. Evidence for the recommended dosage of tricyclics, however, is poor. ⋯ Treatment of depression in adults with low dose tricyclics is justified. However, more rigorous studies are needed to definitively establish the relative benefits and harms of varying dosages.

Review Meta AnalysisSelenium supplementation to prevent short-term morbidity in preterm neonates.
Selenium is an essential trace element and component of a number of selenoproteins including glutathione peroxidase, which has a role in protecting against oxidative damage. Selenium is also known to play a role in immunocompetence. Blood selenium concentrations in newborns are lower than those of their mothers and lower still in preterm infants. In experimental animals low selenium concentrations appear to increase susceptibility to oxidative lung disease. In very preterm infants low selenium concentrations have been associated with an increased risk of chronic neonatal lung disease and retinopathy of prematurity. ⋯ Supplementing very preterm infants with selenium is associated with benefit in terms of a reduction in one or more episodes of sepsis. Supplementation was not associated with improved survival, a reduction in neonatal chronic lung disease or retinopathy of prematurity. Supplemental doses of selenium for infants on parenteral nutrition higher than those currently recommended may be beneficial. The data are dominated by one large trial from a country with low selenium concentrations and may not be readily translated to other populations.
