ReviewInhaled corticosteroid effects on bone metabolism in asthma and mild chronic obstructive pulmonary disease.
Inhaled corticosteroids form the main therapy for asthma, but there is increasing concern about the potential systematic effects of long-term inhaled corticosteroids including their effect on bone metabolism and bone loss. ⋯ In patients with asthma or mild COPD, there is no evidence of an effect of inhaled corticosteroid at conventional doses given for two or three years on BMD or vertebral fracture. Higher doses were associated with biochemical markers of increased bone turnover, but data on BMD and fractures at these doses are not available. There is a need for further, even longer term prospective studies of conventional and high doses of inhaled corticosteroids.

ReviewEarly versus delayed initiation of continuous distending pressure for respiratory distress syndrome in preterm infants.
The application of a continuous distending pressure (CDP) has been shown to have some benefits in the treatment of pre-term infants with respiratory distress syndrome (RDS). CDP has the potential to reduce lung damage, particularly if applied early before atelectasis has occurred. Early application of CDP may better conserve an infant's own surfactant stores and consequently be more effective than CDP applied later in the course of RDS. ⋯ Early application of CDP has a clinical benefit in the treatment of RDS in that it reduces subsequent use of IPPV and thus may be useful in preventing the adverse effects of this treatment. However, many of the trials were done in the 1970s and 1980s and re-evaluation of the strategy of early CDP in the era of antenatal steroid use and early surfactant administration is indicated.

This review is one in a series of reviews of interventions for lateral elbow pain. Lateral elbow pain, or tennis elbow, is a common condition causing pain in the elbow and forearm and lack of strength and function of the elbow and wrist. Shock wave therapy (ESWT) involves the application of single pulsed acoustic wave. Since the 1990's reports of benefit of ESWT in the treatment of tendon disorders have been appearing in the literature. A systematic review published in the German language appeared in 2000 (Boddeker 2000) ⋯ The two trials included in this review yielded conflicting results. Further trials are needed to clarify the value of ESWT for lateral elbow pain.

The majority of people with epilepsy have a good prognosis and their seizures can be well controlled with the use of a single antiepileptic agent, but up to 30 per cent develop refractory epilepsy, especially those with partial seizures. In this review we summarize the current evidence regarding zonisamide, when used as an add-on treatment for drug-resistant partial epilepsy. ⋯ Zonisamide has efficacy as an add-on treatment in people with drug-resistant partial epilepsy. Minimum effective and maximum tolerated doses cannot be identified. The trials reviewed were of 12 week duration and results cannot be used to confirm longer periods of effectiveness in seizure control. The results cannot be extrapolated to monotherapy or to people with other seizure types or epilepsy syndromes.

Induced hypothermia has been used in the treatment of head injury for many years. Encouraging results from small trials and laboratory studies led to renewed interest in the area and some larger trials. ⋯ There is no evidence that hypothermia is beneficial in the treatment of head injury. The earlier, encouraging, trial results have not been repeated in larger trials. The reasons for this are unclear. Hypothermia increases the risk of pneumonia and has other potentially harmful side effects. Therefore, it would seem inappropriate to use this intervention outside of controlled trials in subgroups of patients for whom there is good reason to think the treatment would be beneficial.
