Review Meta AnalysisAction plans for chronic obstructive pulmonary disease.
The effectiveness of action plans as treatment for chronic obstructive pulmonary disease (COPD) is not known. ⋯ This review shows there is evidence that action plans aid people with COPD in recognising and reacting appropriately to an exacerbation of their symptoms via the self-initiation of antibiotics or steroids. Further research needs to be completed with more comprehensive outcomes measures in order to ascertain whether this results in significantly decreased morbidity and/or mortality.

Cervical dystonia is the most common form of focal dystonia. It is characterized by involuntary posturing of the head and frequently is associated with neck pain. Disability and social withdrawal are common. Most cases of cervical dystonia are idiopathic and generally it is a life-long disorder. In recent years, Botulinum toxin type A (BtA) has become the first line therapy. However, some patients become resistant to it. This problem led to the study of another Botulinum toxin (Bt) serotype, Bt type B (BtB) to address the issues of clinical efficacy, effect size, and safety of BtB in the treatment of cervical dystonia. ⋯ A single injection of BtB was effective and safe for treating cervical dystonia. Long-term uncontrolled studies suggested that further injection cycles continue to work for most patients. Future research should explore technical factors such as the optimum treatment intervals and use of image or electromyographic guidance for administration. Other issues include service delivery, quality of life, long-term efficacy and safety, and the relative indications for BtA, BtB and other treatments such as deep brain stimulation.

Review Meta AnalysisVitamin D and vitamin D analogues for preventing fractures associated with involutional and post-menopausal osteoporosis.
Vitamin D and related compounds have been used to prevent fractures. ⋯ Frail older people confined to institutions may sustain fewer hip and other non-vertebral fractures if given vitamin D with calcium supplements. Effectiveness of vitamin D alone in fracture prevention is unclear. There is no evidence of advantage of analogues of vitamin D compared with vitamin D. Calcitriol may be associated with an increased incidence of adverse effects. Dose, frequency, and route of administration of vitamin D in older people require further investigation.

Review Meta AnalysisHyperbaric oxygen therapy for acute coronary syndrome.
Acute coronary syndrome (ACS) includes acute myocardial infarction and unstable angina. ACS is common and may prove fatal. Hyperbaric oxygen therapy (HBOT) will improve oxygen supply to the threatened heart and may reduce the volume of heart muscle that will perish. The addition of HBOT to the standard treatment may reduce death rate and other major adverse outcomes. ⋯ For people with ACS, individual small trials suggest the addition of HBOT reduced the risk of Major Adverse Cardiac Events, some dysrrhythmias, and reduced the time to relief from ischaemic pain, but did not reduce mortality. In view of the modest number of patients, methodological shortcomings and poor reporting, this result should be interpreted cautiously, and an appropriately powered trial of high methodological rigour is justified to define those patients (if any) who can be expected to derive most benefit from HBOT. The routine application of HBOT to these patients cannot be justified from this review.

Review Meta AnalysisChest physiotherapy for acute bronchiolitis in paediatric patients between 0 and 24 months old.
Acute bronchiolitis is the leading causes of medical emergencies during winter in children younger than two years of age. Chest physiotherapy is thought to assist infants in the clearance of secretions and decrease ventilatory effort. ⋯ Based on the results of three RCTs, chest physiotherapy using vibration and percussion techniques does not reduce length of hospital stay, oxygen requirements, or improve the severity clinical score in infants with acute bronchiolitis that are not under mechanical ventilation, and who do not have any other co-morbidity. Chest physiotherapy using forced expiratory technique needs to be evaluated by clinical research.
