Reported are the results of a study of residents' knowledge about malaria and antimalarial drugs and of their treatment-seeking behaviour in a rural area of western Kenya. The study subjects were generally well-informed about the symptoms of the disease. Malaria was perceived as a relatively mild illness, much less severe than acquired immunodeficiency syndrome (AIDS), measles, difficulty in breathing, and diarrhoea. ⋯ Commercially available chloroquine preparations were perceived as more effective than either antipyretics or herbal remedies for the treatment of malaria, and injections were regarded as more effective than oral medications. 4-Amino-quinolines were used to treat 58% of febrile illnesses but in only 12% of the cases was a curative dose of > or = 25 mg/kg body weight employed. Even attendance at a health centre did not ensure adequate treatment because of the common practice of sharing medication among family members. Greatly increased attention should be paid to the role of home treatment of malaria when policies are being developed for the management of febrile illnesses in sub-Saharan Africa.

Respiratory rate and signs in roentgenographically confirmed pneumonia among children in China.
A clinical study was conducted in three Chinese community hospitals to investigate the reliability of respiratory rate and various clinical signs in the diagnosis of pneumonia among 54 children less than 5 years of age. Anteroposterior chest film was used as the diagnostic standard. The cutoff criterion for rapid breathing was 50 breaths/minute for infants ages 2 to 11 months and 40/minute in children 1 to 5 years old. ⋯ Nasal flaring, chest indrawing, stridor and cyanosis of the tongue had predictive values of > 86%, but these clinical signs were observed in only a small proportion of patients. We recommend that village health workers use rapid breathing for diagnosis of pneumonia, rather than auscultation which is difficult and has proved unreliable. Sensitivity, specificity and positive and negative predictive values are presented for seven signs and symptoms of pneumonia.

The authors conducted a case-control study of the relation of OC use after conception to the occurrence of congenital urinary tract anomalies (CUTAs). Singleton CUTA cases with no known chromosomal abnormality from seven counties in western Washington State born during the period January 1, 1990-December 31, 1991 were identified through the Washington State Birth Defect Registry. Controls without birth defects were randomly selected from singleton births that occurred in the same year as the cases in five large hospitals in King County. ⋯ Use of other contraceptive methods after conception was not related to the risk of CUTAs. OC use during the 3 or 6 months prior to the conception also was not associated with the risk of CUTAs. Further adjustment for sociodemographic factors, reproductive history, perinatal exposure to exogenous agents, and past OC use did not change the results, nor did restricting the analysis to residents of King County.(ABSTRACT TRUNCATED AT 250 WORDS)
