Spinal cord injury (SCI) results in loss of feeling and movement. The consequences can be devastating for the patient and his or her carers. Global estimates of the number of new cases annually range from 15 to 40 per million. Leading causes of acute SCI are road traffic injury, violence, and injuries sustained in sports and other recreational activities. Care for people with SCI has improved, leading to an increase in survival rates. Attempts to improve patients' feeling and movement have involved the use of a wide range of treatments. Gangliosides are compounds that occur naturally in cell membranes. Laboratory studies have suggested they may have protective effects on nerves and even help them to re-grow. Clinical trials have taken place using gangliosides (usually GM1 ganglioside) for a number of neurological conditions. ⋯ The evidence available does not support the use of ganglioside treatment to reduce the death rate in SCI patients. No evidence has yet emerged that ganglioside treatment improves recovery or quality of life in survivors.

Review Meta AnalysisProstacyclin for pulmonary hypertension in adults.
Primary pulmonary hypertension (PPH) is progressive, resulting in right ventricular failure. Pulmonary hypertension can be idiopathic or associated with other conditions. Prostacyclin is a potent vasodilator and inhibitor of platelet aggregation, and can be given orally, subcutaneously, intravenously or inhaled via a nebuliser. ⋯ There is evidence that intravenous prostacyclin in addition to conventional therapy at tolerable doses optimised by titration, can confer some short-term benefits (up to 12 weeks of treatment) in exercise capacity, NYHA functional class and cardiopulmonary haemodynamics. There is also some evidence that patients with more severe disease based upon NYHA functional class showed a greater response to treatment.

ReviewThe 'WHO Safe Communities' model for the prevention of injury in whole populations.
The safe communities approach has been embraced around the world as a model for coordinating community efforts to enhance safety and reduce injury. Over 80 communities throughout the world have been formally designated as 'Safe Communities' by the World Health Organization. It is of public health interest to determine to what degree the model is successful, and whether its application does indeed reduce injury rates in communities to which it is introduced. ⋯ Evidence suggests the WHO Safe Communities model is effective in reducing injuries in whole populations. However, important methodological limitations exist in all studies from which evidence can be obtained. A lack of reported detail makes it unclear which factors facilitate or hinder a programme's success, and makes uncertain, whether the success of any particular application of the model is necessarily replicable in other communities. In evaluated programmes that did not report significant decreases in injury rates, this lack of information makes it difficult to distinguish between evidence of no effect of the model, or no evidence of effect. The four countries that have evaluated their Safe Communities with a sufficiently rigorous study design have higher economic wealth and health standards and lower injury rates than much of the world. No evaluations were available from other parts of the world, despite the designation of WHO Safe Communities in countries such as South Africa, Bangladesh, China, Vietnam, Canada, UK and USA. Generalisation of results of studies conducted in just four countries, to the international population needs to be done with caution. There is a need for more high-quality, methodologically strong evaluations of the model in a range of diverse communities and detailed reporting of implementation processes.

Psychosocial and emotional factors are important in childhood asthma. Nevertheless, drug therapy alone continues to be the main treatment. Treatment programmes that include behavioural or psychological interventions have been developed to improve disturbed family relations in the families of children with severe asthma. These approaches have been extended to examine the efficacy of family therapy to treat childhood asthma in a wider group of patients. This review systematically examines these studies. ⋯ There is some indication that family therapy may be a useful adjunct to medication for children with asthma. This conclusion is limited by small study sizes and lack of standardisation in the choice of outcome measures.
