RESUMO
Background: Malaria is one of the major vectors borne disease globally responsible for 1 million deaths a year. Changing trends in the causative species and epidemiological distribution have identified icterus and renal involvement as an emerging complication associated with severe mortality in children. The objectives of this study were aimed to study the clinical profile of malaria cases admitted in a pediatric ward. The study also highlights the involvement of renal manifestations in the cases with regard to species distribution and associated complications in the study group.Methods: A prospective study for 14 months was conducted, and all positive cases of malaria admitted in paediatric unit were enrolled and socio demographic data, clinical history were collected, and biochemical investigations were performed and analyzed. SPSS software version 12 was used for analysis. Statistical significance was set at p ?0.05.Results: About 278 subjects with 55.4% males, 44.6% females and with 5-10 years was most common age group. 102 cases of vivax malaria, 152 cases were falciparum and 24 were mixed cases. Cerebral malaria, hyperparasitemia was identified in 28 cases, DIC in 5.04% of cases. Renal involvement was observed in 38.16% of falciparum infections and 27.45% of vivax infections. 68 cases developed acute renal failure as a severe complication.Conclusions: 'Renal involvement is more in falciparum and mixed infections than vivax malaria. Early diagnosis and prompt treatment help in early recovery of cases and halts to progression to renal failure. An urgent need for a biomarker for early identification of renal involvement in malaria before biochemical involvement is detected.
RESUMO
A survey was conducted in Brasília, DF, from January 1999 to March 2001, on tobacco, cotton, tomato, cabbage, soybean, bean, melon, eggplant and the weed Emilia sonchifolia DC, to collect natural enemies of the whiteflies Bemisia tabaci (Gennadius) and Trialeurodes vaporariorum (Westwood). Fourteen predators, twelve parasitoids and two hyperparasitoids were collected. Among the parasitoids, Encarsia inaron (Walker) is recorded for the first time in South America, and E. basicincta Gahan is a new record for Brazil. E. aleurothrixi Evans & Polaszek is recorded for the first time parasitizing B. tabaci. The lady beetles Nephaspis hydra Gordon and Delphastus davidsoni Gordon are registered for the first time preying on B. tabaci.
Uma investigação foi conduzida em Brasília, DF, de janeiro de 1999 até março de 2001, sobre fumo, algodão, tomate, couve, soja, feijão, melão, jiló e a planta daninha Emilia sonchifolia DC, a fim de se obter inimigos naturais das moscas-brancas Bemisia tabaci (Gennadius) e Trialeurodes vaporariorum (Westwood). Ao todo, 14 predadores, 12 parasitóides e dois hiperparasitóides foram coletados. Entre os parasitóides, Encarsia inaron (Walker) ainda não havia sido registrada na América do Sul, e E. basicincta Gahan é um novo registro para o Brasil. E. aleurothrixi Evans & Polaszek é também registrada pela primeira vez parasitando B. tabaci. Os besouros Nephaspis hydra Gordon e Delphastus davidsoni Gordon são registrados pela primeira vez predando B. tabaci.
