Review Meta AnalysisOral evening primrose oil and borage oil for eczema.
Eczema is a chronic inflammatory skin condition, which usually develops in early childhood. Many children outgrow this disorder as they reach secondary school age, and although It may improve with age, there is no cure. Constant itch makes life uncomfortable for those with this condition, no matter what age they are, so it may have a significant effect on a person's quality of life. Its prevalence seems to be increasing as populations move from rural locations to cities. Some people, who do not see an adequate improvement or fear side-effects of conventional medical products, try complementary alternatives to conventional treatment. This is a review of evening primrose oil (EPO) and borage oil (BO) taken orally (by mouth); these have been thought to be beneficial because of their gamma-linolenic acid content. ⋯ Noting that the confidence intervals between active and placebo treatment are narrow, to exclude the possibility of any clinically useful difference, we concluded that further studies on EPO or BO for eczema would be hard to justify.This review does not provide information about long-term use of these products.

Review Meta AnalysisMonoclonal antibody for reducing the risk of respiratory syncytial virus infection in children.
Respiratory syncytial virus (RSV) is one of the most important viral pathogens causing acute respiratory infections in children. It results in about 3.4 million hospitalisations annually in children under five. Palivizumab is an anti-RSV monoclonal antibody, administered intramuscularly at a dose of 15 mg/kg once every 30 days. The efficacy and safety of palivizumab has been evaluated in multicentre, randomised controlled trials (RCTs) and a large number of economic evaluations (EEs) have tested its cost-effectiveness. ⋯ There is evidence that palivizumab prophylaxis is effective in reducing the frequency of hospitalisations due to RSV infection, i.e. in reducing the incidence of serious lower respiratory tract RSV disease in children with chronic lung disease, congenital heart disease or those born preterm.Results from economic evaluations of palivizumab prophylaxis are inconsistent, implying that economic findings must be interpreted with caution. ICER values varied considerably across studies, from highly cost-effective to not cost-effective. The availability of low-cost palivizumab would reduce its inequitable distribution, so that RSV prophylaxis would be available to the poorest countries where children are at greatest risk.

Review Meta AnalysisInterventions for the prevention of mycobacterium avium complex in adults and children with HIV.
Mycobacterium avium complex (MAC) infection is a common complication of advanced acquired immunodeficiency syndrome (AIDS) disease and is an independent predictor of mortality and shortened survival. ⋯ Based on limited data, azithromycin or clarithromycin appeared to be a prophylactic agent of choice for MAC infection. Further studies are needed, especially direct comparison of clarithromycin and azithromycin. In additions, studies that will compare different doses and regimens are needed.

ReviewChinese herbal medicines for induction of remission in advanced or late gastric cancer.
Gastric cancer is difficult to cure once it progresses to an advanced or late stage. Although some chemotherapies or bio-therapies have made progress in the remission of this disease, the mortality from gastric cancer remains high. A variety of Chinese medicinal herbs have been used to treat gastric cancer. ⋯ This review did not provide assured evidence concerning the effectiveness of TCMHs in improving quality of life or rate of remission, alleviating the toxicity or side effects of chemotherapy, or reducing short-term mortality. Limited, weak evidence showed that Huachansu, Aidi, Fufangkushen, and Shenqifuzheng improved leukopenia when used together with chemotherapy; and Huachansu, Aidi, and Fufangkushen were of benefit for adverse events in the digestive system caused by chemotherapy. These TCMHs did not improve the rate of short-term remissions. Large, well designed clinical trials are required urgently before any definite conclusions can be drawn about the value of TCMHs for advanced or late stage gastric cancer.

Review Meta AnalysisParacetamol (acetaminophen) with or without an antiemetic for acute migraine headaches in adults.
This is an updated version of the original Cochrane review published in Issue 11, 2010 (Derry 2010). Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce nausea and vomiting, which are commonly associated with migraine. ⋯ Paracetamol 1000 mg alone is statistically superior to placebo in the treatment of acute migraine, but the NNT of 12 for pain-free response at two hours is inferior to at of other commonly used analgesics. Given the low cost and wide availability of paracetamol, it may be a useful first choice drug for acute migraine in those with contraindications to, or who cannot tolerate, non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin. The addition of 10 mg metoclopramide gives short-term efficacy equivalent to oral sumatriptan 100 mg. Adverse events with paracetamol did not differ from placebo; serious and/or severe adverse events were slightly more common with sumatriptan than with paracetamol plus metoclopramide.
