Randomized Controlled Trial Comparative Study Clinical Trial
Randomised controlled trial of treatment of chronic suppurative otitis media in Kenyan schoolchildren.
The outcomes of treatment of chronic suppurative otitis media (CSOM) are disappointing and uncertain, especially in developing countries. Because CSOM is the commonest cause of hearing impairment in children in these countries, an effective method of management that can be implemented on a wide scale is needed. We report a randomised, controlled trial of treatment of CSOM among children in Kenya; unaffected schoolchildren were taught to administer the interventions. ⋯ Our finding that dry mopping plus topical and systemic antibiotics is superior to dry mopping alone contrasts with that of the only previous community-based trial in a developing country, though it accords with findings of most other trials in developed countries. The potential role of antibiotics needs further investigation. Further, similar trials are needed to identify the most cost-effective and appropriate treatment regimen for CSOM in children in developing countries.

Respiratory rehabilitation is increasingly recognised as an important part of the management of patients with chronic obstructive pulmonary disease (COPD). The widespread application of such programmes should be preceded by evidence of directly attributable improvements in function. We assessed the effect of respiratory rehabilitation on exercise capacity and health-related quality of life (HRQL) in patients with COPD. ⋯ Respiratory rehabilitation relieves dyspnoea and improves the control over COPD. These improvements are clinically important. The value of the improvement in exercise capacity is not clear. Respiratory rehabilitation is an effective part of care in patients with COPD.

Guidelines have been offered on haemoglobin thresholds for blood transfusion in surgical patients. However, good evidence is lacking on the haemoglobin concentrations at which the risk of death or serious morbidity begins to rise and at which transfusion is indicated. ⋯ A low preoperative haemoglobin or a substantial operative blood loss increases the risk of death or serious morbidity more in patients with cardiovascular disease than in those without. Decisions about transfusion should take account of cardiovascular status and operative blood loss as well as the haemoglobin concentration.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Epidermoid anal cancer: results from the UKCCCR randomised trial of radiotherapy alone versus radiotherapy, 5-fluorouracil, and mitomycin. UKCCCR Anal Cancer Trial Working Party. UK Co-ordinating Committee on Cancer Research.
Non-surgical management of anal cancer by radiotherapy alone or combined with chemotherapy has, in uncontrolled studies, yielded similar local tumour control and survival rates to surgery. However, whether the addition of chemotherapy improves outcome without adding to morbidity is not known. Our trial was designed to compare combined modality therapy (CMT) with radiotherapy alone in patients with epidermoid anal cancer. ⋯ Our trial shows that the standard treatment for most patients with epidermoid anal cancer should be a combination of radiotherapy and infused 5-fluorouracil and mitomycin, with surgery reserved for those who fall on this regimen.
