Rosacea is a common chronic skin condition affecting the face, characterised by flushing, redness, pimples, pustules, and dilated blood vessels. The eyes are often involved. Frequently it can be controlled, but it is not clear which treatments are most effective. ⋯ The quality of studies evaluating rosacea treatments was generally poor. There is evidence that topical metronidazole and azelaic acid are effective. There is some evidence that oral metronidazole and tetracycline are effective. There is insufficient evidence concerning the effectiveness of other treatments. Good RCTs looking at these treatments are urgently needed.

Review Meta AnalysisIn vitro fertilisation for unexplained subfertility.
In vitro fertilisation (IVF) is now a widely accepted treatment for unexplained infertility (RCOG 1998). However, with estimated live-birth rates per cycle varying between 13% and 28%, its effectiveness has not been rigorously evaluated in comparison with other treatments. With increasing awareness of the role of expectant management and less invasive procedures such as intrauterine insemination, concerns about multiple complications and costs associated with IVF, it is extremely important to evaluate the effectiveness of IVF against other treatment options in couples with unexplained infertility. ⋯ Any effect of IVF relative to expectant management, clomiphene citrate, IUI with or without ovarian stimulation and GIFT in terms of live-birth rates for couples with unexplained subfertility remains unknown. The studies included are limited by their small sample size so that even large differences might be hidden. Live-birth rates are seldom reported. Periods of follow up are inadequate and unequal. Adverse effects such as multiple pregnancies and ovarian hyperstimulation syndrome have also not been reported in most studies. Larger trials with adequate power are warranted to establish the effectiveness of IVF in these women. Future trials should not only report rates per woman/couple but also include adverse effects and costs of the treatments as outcomes. Factors that have a major effect on these outcomes such as fertility treatment, female partner's age, duration of infertility and previous pregnancy history should also be considered.

Review Meta AnalysisVaccines for measles, mumps and rubella in children.
Public debate over the safety of the trivalent measles, mumps and rubella (MMR) vaccine, and the resultant drop in vaccination rates in several countries, persists despite its almost universal use and accepted effectiveness. ⋯ The design and reporting of safety outcomes in MMR vaccine studies, both pre- and post-marketing, are largely inadequate. The evidence of adverse events following immunisation with MMR cannot be separated from its role in preventing the target diseases.

Review Meta AnalysisInhaled magnesium sulfate in the treatment of acute asthma.
Asthma exacerbations can be frequent and range in severity from relatively mild to status asthmaticus. The use of magnesium sulfate (MgSO4) is one of numerous treatment options available during acute exacerbations. While the efficacy of intravenous MgSO4 has been demonstrated, little is known about inhaled MgSO4. ⋯ Nebulised inhaled magnesium sulfate in addition to beta2-agonist in the treatment of an acute asthma exacerbation, appears to have benefits with respect to improved pulmonary function and there is a trend towards benefit in hospital admission. Heterogeneity between trials included in this review precludes a more definitive conclusion.

Review Meta AnalysisPrimary stenting versus primary balloon angioplasty for treating acute myocardial infarction.
Balloon angioplasty following myocardial infarction (MI) reduces death, non-fatal MI and stroke compared to thrombolytic reperfusion. However up to 50% of patients experience restenosis and 3% to 5% recurrent myocardial infarction. Therefore, primary stenting may offer additional benefits compared to balloon angioplasty in patients with acute myocardial infarction. ⋯ There is no evidence to suggest that primary stenting reduces mortality when compared to balloon angioplasty. Stenting seems to be associated with a reduced risk of reinfarction and target vessel revascularization, but potential confounding due to unbalanced post-interventional antithrombotic/anticoagulant therapies can not be ruled out on basis of this review.
