Review Meta AnalysisInterventions before consultations for helping patients address their information needs.
Patients often do not get the information they require from doctors and nurses. To address this problem, interventions directed at patients to help them gather information in their healthcare consultations have been proposed and tested. ⋯ Interventions before consultations designed to help patients address their information needs within consultations produce limited benefits to patients. Further research could explore whether the quality of questions is increased, whether anxiety before consultations is reduced, the effects on other outcomes and the impact of training and the timing of interventions. More studies need to consider the timing of interventions and possibly the type of training provided to clinicians.

Review Meta AnalysisSurgical management of pelvic organ prolapse in women.
Pelvic organ prolapse may occur in up to 50% of parous women. A variety of urinary, bowel and sexual symptoms may be associated with prolapse. ⋯ Abdominal sacrocolpopexy is associated with a lower rate of recurrent vault prolapse and dyspareunia than the vaginal sacrospinous colpopexy. These benefits must be balanced against a longer operating time, longer time to return to activities of daily living and increased cost of the abdominal approach. The use of mesh or graft inlays at the time of anterior vaginal wall repair may reduce the risk of recurrent cystocele. Posterior vaginal wall repair may be better than transanal repair in the management of rectoceles in terms of recurrence of prolapse. The addition of a continence procedure to a prolapse repair operation may reduce the incidence of postoperative urinary incontinence but this benefit needs to be balanced against possible differences in costs and adverse effects. Adequately powered randomised controlled clinical trials are urgently needed.

Review Meta AnalysisCalcium antagonists for aneurysmal subarachnoid haemorrhage.
Secondary ischaemia is a frequent cause of poor outcome in patients with subarachnoid haemorrhage (SAH). Its pathogenesis has been incompletely elucidated, but vasospasm probably is a contributing factor. Experimental studies have suggested that calcium antagonists can prevent or reverse vasospasm and have neuroprotective properties. ⋯ Calcium antagonists reduce the risk of poor outcome and secondary ischaemia after aneurysmal SAH. The results for 'poor outcome' depend largely on a single large trial of oral nimodipine; the evidence for other calcium antagonists is inconclusive. The evidence for nimodipine is not beyond all doubt, but given the potential benefits and modest risks of this treatment, oral nimodipine is currently indicated in patients with aneurysmal SAH. Intravenous administration of calcium antagonists cannot be recommended for routine practice on the basis of the present evidence. Magnesium sulphate is a promising agent but more evidence is needed before definite conclusions can be drawn.

Review Meta AnalysisPharmacological interventions for epilepsy in people with intellectual disabilities.
The development of epilepsy in a person with intellectual disabilities is a common occurrence. In view of the fact that seizures in intellectually disabled people are often complex and refractory to treatment and that antiepileptic medication may have a profound effect upon behaviour in this patient group, it is evident that good quality randomised controlled trials are needed in this population. ⋯ In summary this review broadly supports the use of AEDs to reduce seizure frequency in people with refractory epilepsy and intellectual disability. The evidence suggests that side effects are similar to those in the general population and that behavioural side effects leading to discontinuation are rare but that other effects are under researched.

Review Meta AnalysisOrthodontic treatment for prominent upper front teeth in children.
Prominent upper front teeth are an important and potentially harmful type of orthodontic problem. This condition develops when the child's permanent teeth erupt and children are often referred to an orthodontist for treatment with dental braces to reduce the prominence of the teeth. If a child is referred at a young age, the orthodontist is faced with the dilemma of whether to treat the patient early or to wait until the child is older and provide treatment in early adolescence. When treatment is provided during adolescence the orthodontist may provide treatment with various orthodontic braces, but there is currently little evidence of the relative effectiveness of the different braces that can be used. ⋯ The evidence suggests that providing early orthodontic treatment for children with prominent upper front teeth is no more effective than providing one course of orthodontic treatment when the child is in early adolescence.
