Tuberculin survey among Afghan refugee children. Tuberculosis control programme among Afghan refugees in North West Frontier Province (NWFP) Pakistan.

Since 1982 over 2 million Afghan refugees have settled in the North West Frontier Province (NWFP) of Pakistan. Socio-economical factors, sudden urbanisation and psychological stress may influence the pattern of tuberculosis morbidity and infection among refugees as compared with the original population. In order to study the prevalence of tuberculous infection among Afghan children a tuberculin survey was carried out in April and May 1985 on a cluster sample of male children attending the first two grades of primary schools in refugee camps in the NWFP.

Helsinki Heart Study: primary-prevention trial with gemfibrozil in middle-aged men with dyslipidemia. Safety of treatment, changes in risk factors, and incidence of coronary heart disease.

In a randomized, double-blind five-year trial, we tested the efficacy of simultaneously elevating serum levels of high-density lipoprotein (HDL) cholesterol and lowering levels of non-HDL cholesterol with gemfibrozil in reducing the risk of coronary heart disease in 4081 asymptomatic middle-aged men (40 to 55 years of age) with primary dyslipidemia (non-HDL cholesterol greater than or equal to 200 mg per deciliter [5.2 mmol per liter] in two consecutive pretreatment measurements). One group (2051 men) received 600 mg of gemfibrozil twice daily, and the other (2030 men) received placebo.
