The treatment of chronic low back pain is not primarily focused on removing an underlying organic pathology, but at the reduction of disability through the modification of environmental contingencies and cognitive processes. Behavioural interventions are commonly used in the treatment of chronic (disabling) low back pain. ⋯ Behavioural treatment seems to be an effective treatment for chronic low back pain patients, but it is still unknown what type of patients benefit most from what type of behavioural treatment.

Posttraumatic stress disorder (PTSD) is a prevalent and disabling disorder. By definition prior psychological trauma plays a causal role in the disorder, and psychotherapy is a widely accepted intervention. Nevertheless there is growing evidence that PTSD is characterized by specific psychobiological dysfunctions, and this has contributed to a growing interest in the use of medication in its treatment. ⋯ Medication treatments can be effective in PTSD, acting to reduce its core symptoms, and should be considered as part of the treatment of this disorder. The existing evidence base does not provide sufficient data to suggest particular predictors of response to treatment, or to demonstrate that any particular class of medication is more effective or better tolerated than any other. However, the largest trials showing efficacy to date have been with the SSRIs, and in contrast, there have been negative studies of some agents. Given the high prevalence and enormous personal and societal costs of PTSD, there is a need for additional controlled trials in this area. Additional questions for future research include the effects of medication on quality of life in PTSD, appropriate dose and duration of medication, the use of medication in different trauma groups, in pediatric and geriatric subjects, and the value of early (prophylactic), combined (with psychotherapy), and long-term (maintenance) medication treatment.

Review Meta AnalysisLong-acting beta2-agonists for chronic obstructive pulmonary disease.
Chronic obstructive pulmonary disease (COPD) is characterised by airflow limitation which is only partially reversible. Long acting beta2-agonists, effective in the management of asthma,are also recommended for COPD management so it is important to establish whether these drugs are effective in reducing COPD symptoms in view of the potential side effect and cost burden. ⋯ Treatment of patients with COPD with long acting beta2-agonists produces only small increases in FEV1. In one study, a dose of salmeterol 50 mcg twice daily produced a reduction in breathlessness and a clinically significant improvement in quality of life. (ABSTRACT TRUNCATED)

ReviewExtubation from low-rate intermittent positive airways pressure versus extubation after a trial of endotracheal continuous positive airways pressure in intubated preterm infants.
Failure of extubation and subsequent reintubation may result in additional stress and trauma to the premature infant. Testing infants about to be extubated with a period of endotracheal CPAP has been suggested as a method of demonstrating readiness for extubation. However, this process has been criticized as increasing the neonate's work of breathing and perhaps increasing the likelihood of extubation failure. ⋯ Preterm infants no longer requiring endotracheal intubation and IPPV should be directly extubated without a trial of ETT CPAP.

ReviewAudit and feedback versus alternative strategies: effects on professional practice and health care outcomes.
Audit and feedback has been identified as having the potential to change the practice of health care professionals. ⋯ It is not possible to recommend a complementary intervention to enhance the effectiveness of audit and feedback. Reminders might be more effective than audit and feedback to improve the delivery of some preventive services but the results are not striking. Few trials have investigated the effect of varying different characteristics of the audit and feedback process. Consideration should be given to testing the effects of modifying important characteristics such as the content, source, timing, recipient and format.
