Review Meta AnalysisInterventions for preventing and treating stress fractures and stress reactions of bone of the lower limbs in young adults.
Stress reaction in bone, which may proceed to a fracture, is a significant problem in military recruits and in athletes, particularly long distance runners. ⋯ The use of shock absorbing inserts in footwear probably reduces the incidence of stress fractures in military personnel. There is insufficient evidence to determine the best design of such inserts but comfort and tolerability should be considered. Rehabilitation after tibial stress fracture may be aided by the use of pneumatic bracing but more evidence is required to confirm this.

Review Meta AnalysisNeuromuscular paralysis for newborn infants receiving mechanical ventilation.
Ventilated newborn infants breathing in asynchrony with the ventilator are at risk for complications during mechanical ventilation, such as pneumothorax or intraventricular hemorrhage, and are exposed to more severe barotrauma, which consequently could impair their clinical outcome. Neuromuscular paralysis, which eliminates spontaneous breathing efforts of the infant, has potential advantages in this respect. However, a number of complications have been reported with muscle relaxation in infants, so that concerns exist regarding the safety of prolonged neuromuscular paralysis in newborn infants. ⋯ For ventilated preterm infants with evidence of asynchronous respiratory efforts, neuromuscular paralysis with pancuronium seems to have a favourable effect on intraventricular hemorrhage and possibly on air leak. Uncertainty remains, however, regarding the long term pulmonary and neurologic effects, and regarding the safety of prolonged use of pancuronium in ventilated newborn infants. There is no evidence from randomized trials on the effects of neuromuscular blocking agents other than pancuronium. The routine use of pancuronium or any other neuromuscular blocking agent in ventilated newborn infants cannot be recommended based on current evidence.

Review Meta AnalysisAlarm interventions for nocturnal enuresis in children.
Enuresis (bedwetting) is a socially disruptive and stressful condition which affects around 15 to 20% of five year olds, and up to 2% of young adults. ⋯ Alarm interventions are an effective treatment for nocturnal bedwetting in children. Alarms appear more effective than desmopressin or tricyclics by the end of treatment, and subsequently. Overlearning (giving extra fluids at bedtime after successfully becoming dry using an alarm), dry bed training and avoiding penalties may further reduce the relapse rate. Better quality research comparing alarms with other treatments is needed, including follow-up to determine relapse rates.

A possible therapeutic effect of diagnostic tubal patency testing has been debated in the literature for half a century. Further debate surrounds whether oil-soluble or water-soluble contrast media might have the bigger fertility-enhancing effect. Historically a variety of agents have been used to 'flush' the fallopian tubes, although tubal flushing does not currently form part of routine practice in the treatment of fertility delay. ⋯ There is evidence of effectiveness of tubal flushing with oil-soluble contrast media in increasing the odds of pregnancy and live birth versus no intervention. The limited evidence of an increase in the odds of live birth from tubal flushing with oil-soluble contrast media versus water-soluble contrast media must be interpreted cautiously. Further robust randomised trials, comparing oil-soluble versus water-soluble media and comparing water-soluble media versus no intervention, would be a useful further guide to clinical practice. Further research is merited to ascertain the mechanism of the fertility enhancing effect of oil-soluble media, as to whether this is a 'tubal flushing' phenomenon, an effect on the intraperitoneal environment, or an implantation enhancing effect on the endometrium.

Spinal cord injury (SCI) results in loss of feeling and movement. The consequences can be devastating for the patient and his or her carers. Global estimates of the number of new cases annually range from 15 to 40 per million. Leading causes of acute SCI are road traffic injury, violence, and injuries sustained in sports and other recreational activities. Care for people with SCI has improved, leading to an increase in survival rates. Attempts to improve patients' feeling and movement have involved the use of a wide range of treatments. Gangliosides are compounds that occur naturally in cell membranes. Laboratory studies have suggested they may have protective effects on nerves and even help them to re-grow. Clinical trials have taken place using gangliosides (usually GM1 ganglioside) for a number of neurological conditions. ⋯ The evidence available does not support the use of ganglioside treatment to reduce the death rate in SCI patients. No evidence has yet emerged that ganglioside treatment improves recovery or quality of life in survivors.
