ReviewSimple urethral dilatation, endoscopic urethrotomy, and urethroplasty for urethral stricture disease in adult men.
Strictures of the urethra are the commonest cause of obstructed micturition in younger men and frequently recur after initial treatment. Standard treatment comprises internal widening of the strictured area by simple dilatation or by telescope-guided internal cutting (optical urethrotomy), but these interventions are associated with a high failure rate requiring repeated treatment. The alternative option of open urethroplasty whereby the urethral lumen is permanently widened by removal or grafting of the strictured segment is less likely to fail but requires greater expertise. Improved choice of graft material and shortened hospital stay suggest urethroplasty may be under used. The extent and quality of evidence guiding treatment choice for this condition is uncertain. ⋯ There were insufficient data to determine which intervention is best for urethral stricture disease in terms of balancing efficacy, adverse effects and costs. Well designed, adequately powered multi-centre trials are needed to answer relevant clinical questions regarding treatment of men with urethral strictures.

Studies in traumatic encephalopathy first led to the insight that the damage seen was not just due to direct consequences of the primary injury. A significant, and potentially preventable, contribution to the overall morbidity arose from secondary hypoxic-ischaemic damage. Brain swelling accompanied by raised intracranial pressure (ICP) resulted in inadequate cerebral perfusion with well-oxygenated blood. Detection of raised ICP could be useful in alerting clinicians to the need to improve cerebral perfusion, with consequent reductions in brain injury. ⋯ There are no data from randomised controlled trials that can clarify the role of ICP monitoring in acute coma.

ReviewBicarbonate versus lactate solutions for acute peritoneal dialysis.
The high mortality rate among critically ill patients with acute kidney injury (AKI) remains an unsolved problem in intensive care medicine, despite the use of renal replacement therapy (RRT). Increasing evidence from clinical studies in adults and children suggests that the new peritoneal dialysis (PD) fluids may allow for better long-term preservation of peritoneal morphology and function. Formation of glucose degradation products (GDPs) can be reduced and even avoided with the use of newer "biocompatible" solutions. However, it is still unclear if there are any differences in using conventional (lactate) solutions compared with low GDP (bicarbonate) solutions for acute PD. ⋯ There is no strong evidence that any clinical advantage for patients requiring acute PD for AKI when comparing conventional (lactate) with low GDP dialysis solutions (bicarbonate).

ReviewDroperidol for treatment of nausea and vomiting in palliative care patients.
Nausea and vomiting are common symptoms in patients with terminal illness and can be very unpleasant and distressing. There are several different types of antiemetic treatments which can be used to control these symptoms. Droperidol is an antipsychotic drug and has been used and studied as an antiemetic in the management of post-operative and chemotherapy nausea and vomiting. ⋯ There is insufficient evidence to advise on the use of droperidol for the management of nausea and vomiting in palliative care. Studies of antiemetics in palliative care settings are needed to identify which agents are most effective with a minimum of side effects.

ReviewRespiratory function monitoring to reduce mortality and morbidity in newborn infants receiving resuscitation.
A respiratory function monitor is routinely used in neonatal intensive care units to continuously measure and display airway pressures, tidal volume and leak during ventilation. During positive pressure ventilation in the delivery room, clinical signs are used to monitor the effectiveness of ventilation. The additional use of a respiratory function monitor during positive pressure ventilation in the delivery room might help to improve the effectiveness of ventilation. ⋯ There is insufficient evidence to determine the efficacy and safety of a respiratory function monitor in addition to clinical assessment during positive pressure ventilation at neonatal resuscitation. Randomised clinical trials comparing positive pressure ventilation with and without a respiratory function monitor in addition to clinical assessment at neonatal resuscitation are warranted.
