Multicenter StudyRisk assessment and other screening options for gonorrhoea and chlamydial infections in women attending rural Tanzanian antenatal clinics.
Sexually transmitted diseases (STDs) are a major cause of morbidity and mortality in developing countries and may play a key role in enhancing the heterosexual transmission of human immunodeficiency virus (HIV). Treatment of STDs is one of the most cost-effective of all health interventions in developing countries; however, STDs among women in rural populations have received little attention. ⋯ The recommended syndromic approach to screening for NG/CT infection, based on reported genital symptoms, had a low sensitivity (43%) and failed to discriminate between infected and uninfected women. A risk score approach that we developed, based on sociodemographic and other factors associated with NG/CT infection, had a higher sensitivity and lower cost per true case treated than other approaches, although its positive predictive value was only about 20%.

High caesarean birth rates are an issue of international public health concern. Determinants of caesarean birth are reviewed in order to formulate strategies to reduce these high rates. ⋯ The risks and safety of caesarean birth differ from place to place in this world. As the relative safety of the procedure is an important factor contributing to the rise of caesarean birth, the fact that this has only been achieved in some parts of the world should restrict the indications to perform the operation in the best interests of pregnant women.

Clinical TrialUse of simple clinical signs to predict pneumonia in young Gambian children: the influence of malnutrition.
The current WHO recommendations for the case management of acute respiratory infections (ARI) in children aged 2 months to 5 years in developing countries use fast breathing (respiratory rate of > or = 50 per minute in children under 12 months and > or = 40 in children aged 12 months to 5 years) and lower chest wall indrawing to determine which child is likely to have pneumonia and should therefore receive antibiotics. We have evaluated these and other physical signs in 487 malnourished children and 255 well nourished children who presented with a cough or breathing difficulty. Pneumonia, defined as definite radiological pneumonia or probable radiological pneumonia associated with crackles on auscultation, was present in 145 (30%) of the malnourished children and 68 (26%) of the well nourished children. ⋯ Intercostal indrawing was more common and lower chest wall indrawing was less common in the malnourished children, with or without pneumonia. These results suggest that fast breathing, as defined at present by WHO, and lower chest wall indrawing are not sufficiently sensistive as predictors of pneumonia in malnourished children. As the latter are a high-risk group, we should like to recommend that children with malnutrition who present with a cough, fast breathing or difficult breathing should be treated with antibiotics.
