Potential interventions for the prevention of childhood pneumonia in developing countries: a meta-analysis of data from field trials to assess the impact of vitamin A supplementation on pneumonia morbidity and mortality. The Vitamin A and Pneumonia Working Group.

Reported are the results of a meta-analysis (12 large-scale field trials in seven countries) of the impact of vitamin A supplementation on pneumonia morbidity and mortality, undertaken as part of a wider review process of a range of possible potential interventions for the prevention of childhood pneumonia. The summary estimate of the relative risk for the impact of vitamin A supplementation on pneumonia incidence was 0.95 (95% confidence interval (CI) = 0.89, 1.01), and for pneumonia mortality, 0.98 (95% CI = 0.75, 1.28). This is in marked contrast to the substantial impact of vitamin A supplementation on all-cause mortality (combined rate ratio (RR) = 0.77, 95% CI = 0.71, 0.84), and on diarrhoea-specific and measles-specific mortality. There was no evidence for a differential impact on pneumonia mortality by age. Since the majority of pneumonia deaths occur in the first year of life, we complemented the paucity of data on pneumonia-specific mortality among this age group with a detailed examination of all-cause mortality among infants. The mortality reduction in the 6-11 month age group was consistent with that observed for older age groups (RR = 0.69; 95% CI = 0.54, 0.90), but there was no reduction for 0-5 month-olds (RR = 0.97; 95% CI = 0.73, 1.29)

Laparoscopic Burch colposuspension after failed sub-urethral tape procedures: a retrospective audit

Our objective was to evaluate the outcome of laparoscopic Burch colposuspension in women with recurrent stress urinary incontinence after failed primary sub-urethral tape procedures. A total of 16 patients were identified, and their data from symptom-specific questionnaires, urodynamic studies and urogynaecological assessment were collected. At a median follow-up of 24.5 months, objective and subjective cure rates were 54.5% and 92.9%, respectively. Average satisfaction score regarding outcome after surgery was 9.3 on a rating scale from 0 to 10. All but one patient had symptoms of urge incontinence pre-operatively with 64.3% experiencing cure or improvement post-operatively. Voiding difficulties were observed in one patient, and post-operative urodynamics revealed a significant decrease in urinary flow rate (p
