Symptomatic benign prostatic obstruction is a common problem for older men. The gold standard treatment, transurethral resection of the prostate (TURP), significantly improves urinary symptoms and urinary flow. However, TURP has up to a 20% morbidity. Currently, there are a number of minimally invasive procedures that may be safe, effective alternatives to TURP. One promising surgical technique is laser prostatectomy. ⋯ Laser techniques are a useful alternative to TURP for treating BPO. Small sample sizes and differences in study design limit any definitive conclusions regarding the preferred type of laser technique. Data were insufficient to compare laser techniques with other minimally invasive procedures.

ReviewInterventions to help external cephalic version for breech presentation at term.
Breech presentation places a fetus at increased risk. The outcome for the baby is improved by planned caesarean section compared with planned vaginal delivery. External cephalic version attempts to reduce the chances of breech presentation at birth, but is not always successful. Tocolytic drugs to relax the uterus as well as other methods have been used in an attempt to facilitate external cephalic version at term. ⋯ Routine tocolysis appears to reduce the failure rate of external cephalic version at term. There is not enough evidence to evaluate the use of fetal acoustic stimulation in midline fetal spine positions, nor of epidural or spinal analgesia. Large volume intravenous preloading may have contributed to the effectiveness demonstrated in two of the latter trials.

Studies have reported high tumour response rates for platinum-containing regimens in the treatment of women with metastatic breast cancer. ⋯ In view of the significant excess toxicity, lack of progression or survival benefit and the availability of less toxic active agents it is difficult to justify the use of platinum-containing regimens, particularly as first line treatment for women with metastatic breast cancer in routine clinical practice. Ongoing trials are examining the possibility of synergy between platins and trastuzamab, a monoclonal antibody treatment. No randomised trials containing oxalplatin were identified for the present review.

ReviewBenzodiazepine receptor antagonists for hepatic encephalopathy.
Hepatic encephalopathy may be associated with accumulation of substances that bind to a receptor-complex in the brain resulting in neural inhibition. Benzodiazepine receptor antagonists may have a beneficial effect on patients with hepatic encephalopathy. ⋯ Flumazenil had a significant beneficial effect on short-term improvement of hepatic encephalopathy in patients with cirrhosis and a highly favourable prognosis. Flumazenil had no significant effect on recovery or survival. Considering the fluctuating nature of hepatic encephalopathy, future trials should use a parallel design and assess if treatment with flumazenil leads to a sustained improvement or increased recovery and survival. Until this has been demonstrated, flumazenil may be considered for patients with chronic liver disease and hepatic encephalopathy, but cannot be recommended for routine clinical use.

ReviewInterventions for improving adherence to treatment in patients with high blood pressure in ambulatory settings.
Lack of adherence to blood pressure lowering medication is a major reason for poor control of hypertension worldwide. Interventions to improve adherence to antihypertensive medication have been evaluated in randomised trials but it is unclear which interventions are effective. ⋯ Reducing the number of daily doses appears to be effective in increasing adherence to blood pressure lowering medication and should be tried as a first line strategy, although there is less evidence of an effect on blood pressure reduction. Some motivational strategies and complex interventions appear promising, but we need more evidence on their effect through carefully designed RCTs.
