Nonabsorbable disaccharides (lactulose or lactitol) are considered the treatment of choice for hepatic encephalopathy. ⋯ This systematic review questions the beneficial effects of nonabsorbable disaccharides and highlights that there is insufficient high-quality evidence to support this treatment. We found that antibiotics appeared to be superior to nonabsorbable disaccharides in improving hepatic encephalopathy, but it is unclear whether this difference in treatment effect is clinically important to patients. Nonabsorbable disaccharides should not serve as comparator in randomised trials on hepatic encephalopathy.

ReviewConservative management for postprostatectomy urinary incontinence.
Urinary incontinence is common after both radical prostatectomy and transurethral resection. Conservative management includes pelvic floor muscle training, biofeedback, electrical stimulation, compression devices (penile clamps), lifestyle changes, extra-corporeal magnetic innervation or a combination of methods. ⋯ The value of the various approaches to conservative management of postprostatectomy incontinence remains uncertain. There may be some benefit of offering pelvic floor muscle training with biofeedback early in the postoperative period immediately following removal of the catheter as it may promote an earlier return to continence. Long-term incontinence may be managed by external penile clamp, but there are safety problems.

ReviewAnti-leukotriene agents compared to inhaled corticosteroids in the management of recurrent and/or chronic asthma in adults and children.
Anti-leukotrienes agents are currently being studied as alternative first line agents to inhaled corticosteroids in mild to moderate chronic asthma. ⋯ Inhaled steroids at a dose of 400 mcg/day of beclomethasone or equivalent are more effective than anti-leukotriene agents given in the usual licensed doses. The exact dose-equivalence of anti-leukotriene agents in mcg of ICS remains to be determined. Inhaled glucocorticoids should remain the first line monotherapy for persistent asthma.

Motion sickness - the discomfort experienced when perceived motion disturbs the organs of balance - may include symptoms such as nausea, vomiting, pallor, cold sweats, hypersalivation, hyperventilation and headaches. The control and prevention of these symptoms have included pharmacological, behavioural and complementary therapies. Although scopolamine has been used in the treatment and prevention of motion sickness for decades, there have been no systematic reviews of its effectiveness. ⋯ The use of scopolamine versus placebo in preventing motion sickness has been shown to be effective. No conclusions can be made on the comparative effectiveness of scopolamine and other agents such as antihistamines and calcium channel antagonists. In addition, no randomised controlled trials were identified that examined the effectiveness of scopolamine in the treatment of established symptoms of motion sickness.

ReviewProphylactic intravenous antifungal agents to prevent mortality and morbidity in very low birth weight infants.
Invasive fungal infection is an increasingly common cause of mortality and morbidity in very low birth weight infants. As the diagnosis is often difficult, and treatment is often delayed, there is a need to assess whether antifungal prophylaxis is beneficial. ⋯ We have found some evidence that prophylactic intravenous fluconazole reduces mortality prior to hospital discharge in very low birth weight infants. The meta-analysis suggests that there will be one fewer death in every nine infants treated with this intervention, but the 95% confidence interval around this estimate of effect is wide. The longer term neurodevelopmental consequences for infants exposed to this intervention remain to be determined. It will be important to identify any subgroups of very low birth weight infants that receive the most benefit from this intervention. There is also a need for further data on the effect of the intervention on the emergence of organisms with stable antifungal resistance.
