ReviewNeuromuscular 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. Therefore, the routine use of pancuronium or any other neuromuscular blocking agent in ventilated newborn infants cannot be recommended based on current evidence.

Radiotherapy is used commonly to provide pain relief for painful bone metastases, and there is a perception that of the three-quarters of patients who achieve pain relief, half of these stay free from pain. However, the precise contribution from radiotherapy may be unclear because of difficulties in assessing the numbers of people achieving relief, the extent of relief and its duration, and the influence of other contemporaneous interventions, such as analgesics. ⋯ Radiotherapy is clearly effective at reducing pain from painful bone metastases. There was no evidence of any difference in efficacy between different fractionation schedules, nor indeed of a dose-response with total dose of radiation. For treatment of generalised bone pain both hemibody irradiation and radioisotopes can reduce the number of painful new sites.

ReviewMultidisciplinary rehabilitation for fibromyalgia and musculoskeletal pain in working age adults.
Non-malignant musculoskeletal pain is an increasing problem in western countries. Fibromyalgia syndrome is an increasing recognised chronic musculoskeletal disorder. ⋯ We conclude that there appears to be little scientific evidence for the effectiveness of multidisciplinary rehabilitation for these musculoskeletal disorders. However, multidisciplinary rehabilitation is a commonly used intervention for chronic musculoskeletal disorders, which cause much personal suffering and substantial economic loss to the society. There is a need for high quality trials in this field.

Recurrent apnea is common in preterm infants, particularly at very early gestational ages. These episodes of loss of effective breathing can lead to hypoxemia and bradycardia which may be severe enough to require resuscitation including use of positive pressure ventilation. Two forms of methylxanthine (caffeine and theophylline) have been used to stimulate breathing and so prevent apnea and its consequences. ⋯ Caffeine appears to have similar short term effects on apnea/bradycardia to theophylline. In view of the other therapeutic advantages of caffeine (a higher therapeutic ratio, more reliable enteral absorption and a longer half life) this is the preferred treatment for apnea in preterm infants. The possibility that higher doses of caffeine might be more effective in extremely preterm infants needs further evaluation in randomized clinical trials.

There is a need to identify effective and safe treatments for depression in children and adolescents. While tricyclic drugs have proven effectiveness in the treatment of depression in adults, individual studies involving children and adolescent have been equivocal. ⋯ Data suggest tricyclic antidepressants are of unlikely benefit in the treatment of depression in pre pubertal children. There is marginal evidence to support the use of tricyclic antidepressants in the treatment of depression in adolescents, although the magnitude of effect is likely to be moderate at best.
