Review Meta AnalysisMonoamine oxidase B inhibitors for early Parkinson's disease.
It has been postulated that monoamine oxidase B (MAO-B) inhibitors alter disease progression in Parkinson's disease (PD). Clinical trials have produced conflicting results. ⋯ MAO-B inhibitors do not appear to delay disease progression but may have a beneficial effect on motor fluctuations. There was no statistically significant effect on deaths although the confidence interval does not exclude a small increase with MAO-B inhibitors. At present we do not feel these drugs can be recommended for routine use in the treatment of early Parkinson's disease but further randomized controlled trials should be carried out to clarify, in particular, their effect on deaths and motor complications.

Review Meta AnalysisConcomitant chemotherapy and radiation therapy for cancer of the uterine cervix.
The National Cancer Institute (USA) alert in February 1999 stated that concomitant chemoradiotherapy should be considered for all patients with cervical cancer, based on evidence from five randomised controlled trials (RCTs). ⋯ Concomitant chemoradiation appears to improve overall survival and progression-free survival in locally advanced cervical cancer. It also appears to reduce local and distant recurrence suggesting concomitant chemotherapy may afford radiosensitisation and systemic cytotoxic effects. Some acute toxicity is increased, but the long-term side effects are still not clear.

Review Meta AnalysisAdrenergic drugs for urinary incontinence in adults.
Adrenergic drugs have been used for the treatment of urinary incontinence. However, they have generally been considered to be ineffective or to have side effects which may limit their clinical use. ⋯ There was weak evidence to suggest that use of an adrenergic agonist was better than placebo treatment. There was not enough evidence to assess the effects of adrenergic agonists when compared to or combined with other treatments. Further larger trials are needed to identify when adrenergics may be useful. Patients using adrenergic agonists may suffer from minor side effects, which sometimes cause them to stop treatment. Rare but serious side effects, such as cardiac arrhythmias and hypertension, have been reported.

Review Meta AnalysisWhich anticholinergic drug for overactive bladder symptoms in adults.
Around 16% to 45% of adults have overactive bladder symptoms (urgency with frequency and/or urge incontinence - 'overactive bladder syndrome'). Anticholinergic drugs are common treatments. ⋯ Where the prescribing choice is between oral immediate release oxybutynin or tolterodine, tolterodine might be preferred for reduced risk of dry mouth. With tolterodine, 2 mg twice daily is the usual starting dose, but a 1 mg twice daily dose might be equally effective with less risk of dry mouth. If extended release preparations of oxybutynin or tolterodine are available, these might be preferred to immediate release preparations because there is less risk of dry mouth. There is little or no evidence available about quality of life, costs, or long-term outcome in these studies. There were insufficient data from trials of other anticholinergic drugs to draw any conclusions.

Review Meta AnalysisProphylactic nasal continuous positive airways pressure for preventing morbidity and mortality in very preterm infants.
Cohort studies (Avery 1987; Jonsson 1997) have suggested that early post-natal nasal continuous positive airways pressure (CPAP) may be beneficial in reducing the need for intubation and intermittent positive pressure ventilation, and in preventing chronic lung disease in preterm or low birth weight infants. ⋯ There is currently insufficient information to evaluate the effectiveness of prophylactic nasal CPAP in very preterm infants. Neither of the included studies reviewed showed evidence of benefit in reducing the use of IPPV. The tendency for some adverse outcomes to be increased is of concern and further multicentre randomized controlled trials are needed to clarify this.
