Review Meta AnalysisExercise for treating isolated anterior cruciate ligament injuries in adults.
The anterior cruciate ligament (ACL) is the most frequently injured ligament of the knee. Injury causes pain, effusion and inflammation leading to the inability to fully activate the thigh muscles. Regaining muscular control is essential if the individual wishes to return to pre-injury level of function and patients will invariably be referred for rehabilitation. ⋯ This review has demonstrated an absence of evidence to support one form of exercise intervention against another and the use of supplementary exercises in the management of isolated ACL injuries. Further research in the form of large scale well designed randomised controlled trials with suitable outcome measures and surveillance periods, using standardised reporting should be considered.

Review Meta AnalysisLow level laser therapy (Classes I, II and III) for treating rheumatoid arthritis.
Rheumatoid arthritis (RA) affects a large proportion of the population. Low Level Laser Therapy (LLLT) was introduced as an alternative non-invasive treatment for RA about ten years ago. LLLT is a light source that generates extremely pure light, of a single wavelength. The effect is not thermal, but rather related to photochemical reactions in the cells. The effectiveness of LLLT for rheumatoid arthritis is still controversial. This review is an update of the original review published in October 1998. ⋯ LLLT could be considered for short-term treatment for relief of pain and morning stiffness for RA patients, particularly since it has few side-effects. Clinicians and researchers should consistently report the characteristics of the LLLT device and the application techniques used. New trials on LLLT should make use of standardized, validated outcomes. Despite some positive findings, this meta-analysis lacked data on how LLLT effectiveness is affected by four important factors: wavelength, treatment duration of LLLT, dosage and site of application over nerves instead of joints. There is clearly a need to investigate the effects of these factors on LLLT effectiveness for RA in randomized controlled clinical trials.

Review Meta AnalysisTreadmill training and body weight support for walking after stroke.
Treadmill training, with or without some body weight supported using a harness, is a method of treating walking after stroke. A systematic review is required to assess the cost, effectiveness, and acceptability of this treatment. ⋯ Overall no statistically significant effect of treadmill training with or without body weight support was detected. Although individual studies suggested that treadmill training with body weight support may be more effective than treadmill training alone and that treadmill training plus task-oriented exercise may be more effective than sham exercises, further trials are required to confirm these findings.

Review Meta AnalysisCardioselective beta-blockers for chronic obstructive pulmonary disease.
Beta-blocker therapy has a proven mortality benefit in patients with hypertension, heart failure and coronary artery disease, as well as during the perioperative period. These drugs have traditionally been considered contraindicated in patients with chronic obstructive pulmonary disease (COPD). ⋯ Cardioselective beta-blockers, given to patients with COPD in the identified studies did not produce adverse respiratory effects. Given their demonstrated benefit in conditions such as heart failure, coronary artery disease and hypertension, cardioselective beta-blockers should not be routinely withheld from patients with COPD.

Randomised clinical trials have addressed the question whether propylthiouracil has any beneficial effects in patients with alcoholic liver disease. ⋯ We could not demonstrate any significant beneficial effect of propylthiouracil on all-cause mortality, liver-related mortality, liver complications, and liver histology of patients with alcoholic liver disease. Propylthiouracil was associated with adverse events. Confidence intervals were wide. Accordingly, there is no evidence for using propylthiouracil for alcoholic liver disease outside randomised clinical trials.
