Various solutions have been recommended for cleansing wounds, however normal saline is favoured as it is an isotonic solution and does not interfere with the normal healing process. Tap water is commonly used in the community for cleansing wounds because it is easily accessible, efficient and cost effective, however, there is an unresolved debate about its use. ⋯ Although the evidence is limited one trial has suggested that the use of tap water to cleanse acute wounds reduces the infection rate and other trials conclude that there is no difference in the infection and healing rates between wounds that were not cleansed and those cleansed with tap water and other solutions. However the quality of the tap water should be considered prior to its use and in the absence of potable tap water, boiled and cooled water as well as distilled water can be used as wound cleansing agents.

The prevalence of obesity and overweight is increasing in both adult and child populations throughout the world. Obesity in children impacts on their health in both the short and longer term, and obesity prevention is an international public health priority. However, the efficacy of prevention strategies is poorly understood. ⋯ There is limited high quality data on the effectiveness of obesity prevention programs and no generalisable conclusions can be drawn. However, concentration on strategies that encourage reduction in sedentary behaviours and increase in physical activity may be fruitful. The need for well-designed studies that examine a range of interventions remains a priority, although a number of important studies are underway.

Review Meta AnalysisRegular treatment with long acting beta agonists versus daily regular treatment with short acting beta agonists in adults and children with stable asthma.
Selective beta-adrenergic agonists for use in asthma are: short acting (2-6 hours) and long acting (>12 hours). There has been little controversy about using short acting beta-agonists intermittently, but long acting beta-agonists are used regularly, and their regular use has been controversial. ⋯ Long acting inhaled beta-agonists have advantages across a wide range of physiological and clinical outcomes for regular treatment.

Paracetamol (acetaminophen) is widely used for treating fever in children. Like ibuprofen, aspirin, and physical methods (such as fanning), paracetamol aims to provide relief from symptoms and prevent febrile convulsions. Uncertainty exists about the benefits of using it to treat fever in children. ⋯ Trial evidence that paracetamol has a superior antipyretic effect than placebo is inconclusive. There is limited evidence that there is no difference between the antipyretic effect of paracetamol and physical methods. Data on adverse events in these trials were limited. Establishing standard outcomes will help comparisons between studies and meta-analysis.

Fracture of the distal radius is a common clinical problem, particularly in older white women with osteoporosis. ⋯ The available evidence from randomised trials is insufficient to establish the relative effectiveness of the various interventions used in the rehabilitation of adults with fractures of the distal radius.
