Review Meta AnalysisOral vasodilators for primary Raynaud's phenomenon.
Many different drugs have been suggested for the symptomatic treatment of primary Raynaud's phenomenon. Apart from calcium channel blockers, which are considered the drugs of choice, the evidence of the effects of alternative pharmacological treatments is limited. ⋯ Poor methodological quality, small sample sizes and the limited data available resulted in low precision of the statistical results and limited value of the overall results . The overall results show that there is no evidence for an effect of vasodilator drugs on primary Raynaud's phenomenon.

Review Meta AnalysisOestrogens for preventing recurrent urinary tract infection in postmenopausal women.
Recurrent urinary tract infection (RUTI) is defined as three episodes of urinary tract infection (UTI) in the previous 12 months or two episodes in the last six months. The main factors associated with RUTI in postmenopausal women are vesical prolapse, cystocoele, post-voidal residue and urinary incontinence, all associated with a decrease in oestrogen. The use of oestrogens to prevent RUTI has been proposed. ⋯ Based on only two studies comparing vaginal oestrogens to placebo, vaginal oestrogens reduced the number of UTIs in postmenopausal women with RUTI, however this varied according to the type of oestrogen used and the treatment duration.

Review Meta AnalysisInformation provision for stroke patients and their caregivers.
Research shows that stroke patients and their families are dissatisfied with the information provided and have a poor understanding of stroke and associated issues. ⋯ There is evidence that information improves patient and carer knowledge of stroke, aspects of patient satisfaction, and reduces patient depression scores. However, the reduction in depression scores was small and probably clinically insignificant. Although the best way to provide information is still unclear there is some evidence that strategies that actively involve patients and carers and include planned follow up for clarification and reinforcement have a greater effect on patient mood.

Healthcare professionals frequently advise patients to improve their health by stopping smoking. Such advice may be brief, or part of more intensive interventions. ⋯ Simple advice has a small effect on cessation rates. Assuming an unassisted quit rate of 2 to 3%, a brief advice intervention can increase quitting by a further 1 to 3%. Additional components appear to have only a small effect, though there is a small additional benefit of more intensive interventions compared to very brief interventions.

ReviewAdjuvant treatment of anaplastic oligodendrogliomas and oligoastrocytomas.
AO and AOA are known to be chemosensitive tumors. However, the impact of adding chemotherapy to surgery and radiotherapy has not been studied. Also, the value of chromosome 1p and 19q deletions as prognostic and predictive markers is only beginning to be defined. ⋯ Early PCV chemotherapy in addition to standard treatment of surgery and RT does not improve OS in patients with AO or AOA. However, it does improve PFS. It also is associated with significant toxicities. Tumors with 1p and 19q co-deletions are associated with better OS and may indicate a more chemo-responsive tumor.
