[Incidence and risk factors for diarrhoea and acute respiratory infections in urban communities of Pernambuco, Brazil]. / Incidência e fatores de risco de diarréia e infecções respiratórias agudas em comunidades urbanas de Pernambuco, Brasil.

Magnitude and distribution of Diarrhoea and Acute Respiratory Infections (ARI) in children were studied within a larger broader research that focused on health education. Two household surveys were conducted in a sample of families with at least one child under five years of Recife and Olinda in April-May 1992 and 1994. The total number of children studied was 5,436. The estimated adjusted annual incidence rate (AAIR) of diarrhoea was 2.7 episodes per child. The two-week incidence rate of diarrhoea was 10.2% for both years. Risk factors associated with higher incidence of diarrhoea were age (under two years), lack of sanitation facilities, and absence of electrical appliances in the household. Estimated AAIR of ARI was 9. 5 episodes per child. The two-week incidence rate of ARI was 41.0% in 1992 and 32.6% in 1994. Majority of ARIs affected the upper respiratory tract (75.9%). The only factor consistently associated with a higher risk of ARI was age (under three years). Study results indicate that both pathologies are still an important health problem for children under five in Pernambuco. In particular, in the case of diarrhoea the need for improving the access to basic services, such as water supply and sewage system is urgently needed.

[Single dose mebendazole for the treatment of Trichuris trichiura and Necator americanus in chemotherapeutic control campaigns in the communities]. / Estudio de dosis única de mebendazol para el tratamiento de Trichuris trichiura y Necator americanus en campañas de control quimioterapéutico en las comunidades.

A study of intestinal parasitism is made in "Argelia Libre" community, Isle of Youth, by means of four coproparasitologic techniques: Kato Kratz, Ritchie, Direct, and Willis. Patients with geohelminths are divided into two groups of treatment: Group A, treated with 500 mg mebendazole in single doses and group B, treated with the classical scheme of 100 mg every 12 hours for three days. Results of treatment are expressed in terms of cure rates and percentage of egg-count reduction. When comparing schemes A and B, no significant differences are found (p less than 0.05). Due to its lower cost and easier administration, the single dosage scheme is recommended for massive chemotherapy of geohelminthiasis in the community.
