Review Meta AnalysisMethyl-xanthines for exacerbations of chronic obstructive pulmonary disease.
International guidelines currently recommend the use of methyl-xanthines for exacerbations of chronic obstructive pulmonary disease (COPD) for patients who have incomplete responses to bronchodilators. However, available clinical trials are small and underpowered to evaluate the benefits and risks of methyl-xanthines in this acute setting. ⋯ There is no evidence to support the routine use of methyl-xanthines for COPD exacerbations. Methyl-xanthines do not appreciably improve FEV1 during COPD exacerbations and cause adverse effects; evidence of their effect on admissions is limited.

Review Meta AnalysisCardioselective beta-blocker use in patients with reversible airway disease.
Beta-blocker therapy has 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 reversible airway disease. ⋯ Cardioselective beta-blockers, given to patients with mild-moderate reversible airway disease, do not produce clinically significant adverse respiratory effects in the short term. It is not possible to comment on their effects in patient with more severe or less reversible disease, or on their effect on the frequency or severity of acute exacerbations. Given their demonstrated benefit in conditions such as heart failure, coronary artery disease and hypertension, cardioselective beta-blockers should not be withheld from patients with mild-moderate reversible airway disease.

Review Meta AnalysisEarly use of inhaled corticosteroids in the emergency department treatment of acute asthma.
Systemic corticosteroid therapy is central to the management of acute asthma The use of ICS may also be beneficial in this setting. ⋯ Inhaled steroids reduced admission rates in patients with acute asthma, but it is unclear if there is a benefit of ICS when used in addition to systemic corticosteroids. There is insufficient evidence that ICS therapy results in clinically important changes in pulmonary function or clinical scores when used in acute asthma. Similarly, there is insufficient evidence that ICS alone is as effective as CS. Further research is needed to clarify if there is a benefit of ICS when used in addition to CS.

Review Meta AnalysisAntidepressants versus placebo for people with bulimia nervosa.
Bulimia Nervosa (BN) represents an important public health problem and is related to serious morbidity and even mortality. This review attempted to systematically evaluate the use of antidepressant medications compared with placebo for the treatment of bulimia nervosa. ⋯ The use of a single antidepressant agent was clinically effective for the treatment of bulimia nervosa when compared to placebo, with an overall greater remission rate but a higher rate of dropouts. No differential effect regarding efficacy and tolerability among the various classes of antidepressants could be demonstrated.

A variety of manual therapies with similar postulated biologic mechanisms of action are commonly used to treat patients with asthma. Manual therapy practitioners are also varied, including physiotherapists, respiratory therapists, chiropractic and osteopathic physicians. A systematic review across disciplines is warranted. ⋯ There is insufficient evidence to support the use of manual therapies for patients with asthma. There is a need to conduct adequately-sized RCTs that examine the effects of manual therapies on clinically relevant outcomes. Future trials should maintain observer blinding for outcome assessments, and report on the costs of care and adverse events. Currently, there is insufficient evidence to support or refute the use of manual therapy for patients with asthma.
