Eletriptan (Relpax) is a new triptan soon to be made available by prescription for the treatment of acute migraine. Currently five triptans are available by prescription and more are under development. In light of the many drugs for treating acute migraine, there is a need for evidence-based assessments to help determine the relative efficacy and harm of these treatments. ⋯ Eletriptan 20 mg, 40 mg and 80 mg are effective for the treatment of an acute migraine attack. Effectiveness is dose-related, with statistically significant differences between doses for pain-free response and 24-hour outcomes. Eletriptan compares well with other triptans available for outcomes measured up to 2 hours and provides meaningful relief for 24 hours. Taken as a single dose, eletriptan was well tolerated and caused no major harm. The incidence of minor harm was dose-dependent, with 80 mg giving significantly more adverse effects than 40 mg.

ReviewDietary advice for treatment of type 2 diabetes mellitus in adults.
While initial dietary management immediately after formal diagnosis is an 'accepted' cornerstone of treatment of type 2 diabetes mellitus, a formal and systematic overview of its efficacy and method of delivery is not currently available. ⋯ There are no high quality data on the efficacy of the dietary treatment of type 2 diabetes, however the data available indicate that the adoption of exercise appears to improve glycated haemoglobin at six and twelve months in people with type 2 diabetes. There is an urgent need for well-designed studies which examine a range of interventions, at various points during follow-up, although there is a promising study currently underway.

ReviewPatient isolation measures for infants with candida colonization or infection for preventing or reducing transmission of candida in neonatal units.
Candida is one of the most common nosocomial infections in the intensive care setting worldwide and is associated with increased healthcare costs. In neonates, candida infection is associated with high mortality and morbidity. Candida is transmitted by direct and indirect contact. Routine infection control measures that include standard precautions are routinely employed to prevent spread of nosocomial infections. Patient isolation measures, i.e. single room isolation or cohorting, are usually recommended for infections spread by contact. ⋯ The review found no evidence to either support or refute the use of patient isolation measures (single room isolation or cohorting) in neonates with candida colonization or infection. Despite the evidence for transmission of candida by direct or indirect contact and evidence of cross-infection by health care workers, no standard policy of patient isolation measures beyond routine infection control measures exists in the neonatal unit. There is an urgent need to research the role of patient isolation measures for preventing transmission of candida in the neonatal unit. Cluster randomized trials involving multiple units or hospitals with randomized allocation of one type of patient isolation measure or the other (i.e. single room isolation or cohorting) with careful consideration for determining an appropriate sample size and analysis would be the most appropriate method to research this intervention.

There are a number of different drug treatments for acute migraine, including currently four triptans, with several more likely to become available in the future. There is a need for evidence-based information to help determine the balance of benefit and harm for acute migraine treatment. ⋯ Rizatriptan 5 mg and 10 mg are effective in treating acute migraine, with a dose-related increase in efficacy.

ReviewInterventions for smoking cessation in hospitalised patients.
An admission to hospital provides an opportunity to help people stop smoking. Individuals may be more open to help at a time of perceived vulnerability, and may find it easier to quit in an environment where smoking is restricted or prohibited. Initiating smoking cessation services during hospitalisation may help more people to make and sustain a quit attempt. ⋯ High intensity behavioural interventions that begin during a hospital stay and include at least one month of supportive contact after discharge promote smoking cessation among hospitalised patients. These interventions are effective regardless of the patient's admitting diagnosis. lnterventions of lower intensity or shorter duration have not been shown to be effective in this setting. There is insufficient direct evidence to conclude that adding NRT or bupropion to intensive counselling increases cessation rates over what is achieved by counselling alone, but the evidence of benefit for NRT has strengthened in this update and the point estimates are compatible with research in other settings showing that NRT and bupropion are effective.
