Efeito Conjunto da Exposição à Poluição do Ar e aos Ácaros do Pó Sobre as Vias Aéreas

Introdução: A asma é uma doença respiratória crónica, cujo agravamento pode estar associado a factores ambientais, entre os quais os relacionados com a qualidade do ar. Objectivo: O presente trabalho pretendeu avaliar o efeito da exposição individual a poluentes atmosféricos em termos de função respiratória, num grupo de crianças com história de sibilância, entrando em consideração com o grau de infestação de ácaros do pó doméstico. Métodos: Um grupo de 51 crianças com história de sibilância, seleccionadas através do questionário do estudo ISAAC, foi acompanhado prospectivamente num estudo com medidas repetidas, que envolveu avaliações médicas padronizadas que incluíram a realização de espirometria, avaliação da exposição aos ácaros do pó e cálculo do valor de exposição individual a uma variedade de poluentes do ar: PM10, O3, NO2, benzeno, tolueno, xileno, etilbenzeno e formaldeído. Resultados: Observou -se uma elevada percentagem de colchões com um grau de infestação de ácaros médio ou elevado. Com excepção dos valores de PM10, os valores de exposição aos poluentes do ar não alcançaram valores elevados. Na análise multivariável, tanto os poluentes (designadamente PM10, NO2, benzeno, tolueno e etilbenzeno) como o grau de infestação de ácaros do pó associaram -se a deterioração da função pulmonar. Conclusão: O presente trabalho vem reforçar o interesse da exposição aos poluentes do ar em crianças com história de sibilância, que à semelhança do que acontece com os ácaros do pó influenciam as vias aéreas.

The palm tree Copernicia cerifera (carnaúba) as an ecotope of Rhodnius nasutus in rural areas of the State of Piauí Northeastern Brazil

The C. cerifera palm tree (carnaúba) is widely distributed in the Northeastem Brazil, including the State of Piauí. This investigation revealed that R. nasutus is the ortly triatomine species captured on that palm tree, in five different localities. 78% of palm trees were infested with triatomines, and 4.0% were infected with flagellates morphologically and biologically indistinguishable from Trypanosoma cruzi. Birds, rodents and marsupials were found as major blood meai sources for R. nasutus.

Usefulness of serology for the evaluation of Trypanosoma cruzi transmission in endemic areas of Chagas' disease

Thirteen communities from 7 Argentinian provinces were selected for the evaluation of serology as an indicator of transmission of Chagas disease. Of the communities appraised, 6 did not have a history of previous treatment with insecticides and 7 had received sporadic or continuous insecticide treatment. The inhabitants of 20% of the houses of each locality were studied by serology. The samples were obtained byfinger pricking and 50 fil of blood were mixed with 150μl of 50% glycerine solution in tissue culture media to be assayed by Indirect Hemagglutination and Indirect Immunofluorescence tests. In untreated areas, the prevalence of infection in infants 0-4 years old was 17.5%, reaching to over 22% for the 5-9 year old group, and to 33.3% in 10-14 year old individuals. The prevalence in treated and surveyed areas was 2.6% in 0-4 year old children, 5.4% in 5-9 year old and 6,2% in 10-14 year old youngsters. The differences between both areas were statistically significant (p < 0.005). This study favors serology as a valid indicator for the evaluation of transmission of Chagas disease in rural areas.

Environmental contamination by Toxocara sp eggs in public areas of Salvador, Bahia state, Brazil

A survey ofparasite eggs and cysts in soil and dog feces collected in public places of 23 boroughs of Salvador, a city in the Northeast of Brazil, was performed. High degree of contamination by Toxocara sp eggs was observed in all boroughs studied; other parasites found included: Ascaris lumbricoides, hookworms, whipworms and protozoan cysts. Parks andpublic gardens were more contaminated than streets and beachesfor all parasites, including Toxocara sp.

Comparative clinical and ultrasound study of egg-negative and egg-positive individuals from Schistosoma mansoni low morbidity endemic areas, and hospitalized patients with hepatosplenic disease

Two hundred and twenty three subjects from a Schistosoma mansoni low morbidity endemic area and nine hospitalized hepatosplenic patients were submitted to stool test and clinical examination and abdomen ultrasound assessments. According to stool examination and ultrasound results, they were grouped as follows: G1 - 63 Schistosoma mansoni egg-negative individuals; G2 - 141 egg-positive patients and without evidence of periportal fibrosis; G3 - 19 egg-positive patients with periportal echogenicity (3-6mm); and G4 - 9 hepatosplenic patients with periportal echogenicity (> 6mm). Hepatomegaly detected by physical examination of the abdomen evaluated in the midclavicular line was verified in G1, G2 and G3, respectively, in 11.1, 12.1 and 26.3%. In G1, G2 and G3, periportal thickening occurred only in schistosomal patients (8.5%). Mild pathological alterations in patients that cannot yet be detected by clinical examination were detectable in the liver by ultrasound and can be due to fibrosis. The degree of mild periportal fibrosis was diminished in 57.9% of patients 12 months after treatment of schistosomiasis with oxamniquine. At ultrasonography, the mean liver left lobe measurement of G3 was larger than that of G1, and that of G4 larger than that of G1 and G2. The mean size of the spleen of G4 was significantly larger than that of the other three groups, and that of G3 larger than that of G1 and G2.
