The harrowing picture of emaciated terminally ill AIDS patients is a reminder of our lack of understanding of immunological mechanisms that normally control opportunistic infections. Many gastrointestinal pathogens in patients with AIDS are resistant to treatment and lead inexorably to weight loss and death. Although knowledge of the pathogenesis and clinical significance of weight loss has improved considerably, this has not yet led to a sustained effort to improve nutritional status during early stages of disease.

Randomized Controlled Trial Clinical Trial
Dexamethasone in bronchiolitis: a randomised controlled trial.
Although corticosteroids are commonly prescribed in the treatment of bronchiolitis, there is no evidence on the efficacy of these drugs in this disorder. We designed a randomised, double-blind, prospective study to assess the efficacy of dexamethasone in infants with bronchiolitis who require hospital management. ⋯ Our findings do not support the use of dexamethasone in the treatment of bronchiolitis in infants.

The Expert Advisory Group's recommendations to establish cancer centres, cancer units, and a network involving primary care for the treatment of cancer patients in the UK is based on the view that specialisation in cancer care will improve outcomes. Evidence to support the various aspects of specialisation (eg, training, caseload, and the formation of multidisciplinary teams) is strongest for breast cancer, ovarian cancer, and some haematological malignant diseases. There is evidence to support the view that some specialised care can be successfully delivered by a network of district hospitals and main general or teaching hospitals and does not always require referral to cancer centres.
