Review Meta AnalysisInterventions for the prevention and management of oropharyngeal candidiasis associated with HIV infection in adults and children.
Oral candidiasis (OC) associated with human immunodeficiency virus (HIV) infection occurs commonly and recurs frequently, often presenting as an initial manifestation of the disease. Left untreated, these lesions contribute considerably to the morbidity associated with HIV infection. Interventions aimed at preventing and treating HIV-associated oral candidal lesions form an integral component of maintaining the quality of life for affected individuals. ⋯ Five new studies were added to the review, but their results do not alter the final conclusion of the review.Implications for practice Due to there being only one study in children, it is not possible to make recommendations for treatment or prevention of OC in children. Amongst adults, there were few studies per comparison. Due to insufficient evidence, no conclusion could be made about the effectiveness of clotrimazole, nystatin, amphotericin B, itraconazole or ketoconazole with regard to OC prophylaxis. In comparison to placebo, fluconazole is an effective preventative intervention. However, the potential for resistant Candida organisms to develop, as well as the cost of prophylaxis, might impact the feasibility of implementation. No studies were found comparing fluconazole with other interventions. The direction of findings suggests that ketoconazole, fluconazole, itraconazole and clotrimazole improved the treatment outcomes.Implications for research It is encouraging that low-cost alternatives are being tested, but more research needs to be on in this area and on interventions like gentian violet and other less expensive anti-fungal drugs to treat OC. More well-designed treatment trials with larger samples are needed to allow for sufficient power to detect differences in not only clinical, but also mycological, response and relapse rates. There is also a strong need for more research to be done on the treatment and prevention of OC in children as it is reported that OC is the most frequent fungal infection in children and adolescents who are HIV positive. More research on the effectiveness of less expensive interventions also needs to be done in resource-poor settings. Currently few trials report outcomes related to quality of life, nutrition, or survival. Future researchers should consider measuring these when planning trials. Development of resistance remains under-studied and more work must be done in this area. It is recommended that trials be more standardised and conform more closely to CONSORT.

Review Meta AnalysisMagnesium sulphate and other anticonvulsants for women with pre-eclampsia.
Eclampsia, the occurrence of a seizure (fit) in association with pre-eclampsia, is rare but potentially life-threatening. Magnesium sulphate is the drug of choice for treating eclampsia. This review assesses its use for preventing eclampsia. ⋯ Magnesium sulphate more than halves the risk of eclampsia, and probably reduces maternal death. There is no clear effect on outcome after discharge from hospital. A quarter of women report side effects with magnesium sulphate.

Review Meta AnalysisChoice of instruments for assisted vaginal delivery.
Instrumental or assisted vaginal birth is commonly used to expedite birth for the benefit of either mother or baby or both. It is sometimes associated with significant complications for both mother and baby. The choice of instrument may be influenced by clinical circumstances, operator choice and availability of specific instruments. ⋯ There is a recognised place for forceps and all types of ventouse in clinical practice. The role of operator training with any choice of instrument must be emphasised. The increasing risks of failed delivery with the chosen instrument from forceps to metal cup to hand-held to soft cup vacuum, and trade-offs between risks of maternal and neonatal trauma identified in this review need to be considered when choosing an instrument.

Review Meta AnalysisMass media interventions for preventing smoking in young people.
The mass media have been used as a way of delivering preventive health messages. They have the potential to reach and to modify the knowledge, attitudes and behaviour of a large proportion of the community. ⋯ There is some evidence that mass media can prevent the uptake of smoking in young people, however the evidence is not strong and contains a number of methodological flaws.

ReviewHuman albumin for intradialytic hypotension in haemodialysis patients.
Intradialytic hypotension (IDH) occurs in 20% to 55% of haemodialysis sessions and is more frequent among patients on long-term haemodialysis. Symptomatic IDH is generally defined as a decrease in systolic blood pressure (BP) of at least 10 mm Hg or a systolic BP less than 100 mm Hg, with symptoms such as cramps, nausea, vomiting, and dizziness. IDH is managed acutely by volume expansion through the intravenous administration of fluids. ⋯ No randomised or controlled trial was identified comparing albumin to crystalloids (other than normal saline) or non-protein colloids, or a combination of both, in the treatment of symptomatic hypotension during dialysis. One double blind crossover RCT in 45 assessable patients showed that 5% albumin is not superior to normal saline for the treatment of symptomatic hypotension in maintenance haemodialysis patients with a previous history of IDH. Given the cost and relative rarity of albumin use compared to saline, saline should be first line of therapy for treatment of IDH in stable dialysis patients.
