Because hyperventilation is often associated with a rapid fall in intracranial pressure, it has been assumed to be effective in the treatment of severe head injury. Hyperventilation reduces raised intracranial pressure by causing cerebral vasoconstriction and a reduction in cerebral blood flow. Whether reduced cerebral blood flow improves neurological outcome however, is unclear. ⋯ The data available are inadequate to assess any potential benefit or harm that might result from hyperventilation in severe head injury. Randomised controlled trials to assess the effectiveness of hyperventilation therapy following severe head injury are needed.

ReviewMultidisciplinary rehabilitation for fibromyalgia and musculoskeletal pain in working age adults.
Non-malignant musculoskeletal pain is an increasing problem in western countries. Fibromyalgia syndrome is an increasing recognised chronic musculoskeletal disorder. ⋯ We conclude that there appears to be little scientific evidence for the effectiveness of multidisciplinary rehabilitation for these musculoskeletal disorders. However, multidisciplinary rehabilitation is a commonly used intervention for chronic musculoskeletal disorders, which cause much personal suffering and substantial economic loss to the society. There is a need for high quality trials in this field.

Aspirin has been known to be an effective analgesic for many years and is commonly used throughout the world for many different pain conditions. It is important for both prescribers and patients to have the best possible information about the efficacy and safety of analgesics, and this need is reflected in patient surveys which show that postoperative pain is often poorly managed. We also need to benchmark relative efficacy and safety of current analgesics so that we can compare them with new analgesics. ⋯ Aspirin is an effective analgesic for acute pain of moderate to severe intensity with a clear dose-response. Drowsiness and gastric irritation were seen as significant adverse effects even though the studies were single-dose. The pain relief achieved with aspirin was very similar milligram for milligram to that seen with paracetamol.

It is unclear how dysphagic patients should be fed and treated after acute stroke. ⋯ Too few studies have been performed, and these have involved too few patients. PEG feeding may improve outcome and nutrition as compared with NGT feeding. Further research is required to assess how and when patients are fed, and the effect of swallowing or drug therapy on dysphagia.

ReviewChest radiograph in acute respiratory infections in children.
Chest radiography is widely used in acute lower respiratory infection in children, but the benefits are unknown. ⋯ There is no evidence that chest radiography improves outcome in ambulatory children with acute lower respiratory infection. The findings do not exclude a potential effect of radiography, but the potential benefit needs to be balanced against the hazards and expense of chest radiography. The findings apply to ambulatory children only.
