Este artigo faz uma revisão das principais abordagens teóricas da área da Saúde em relação ao estudo das doenças resultantes das mudanças ambientais e a ocorrência de doenças emergentes no Brasil. Apresenta, de forma geral, a dinâmica de transmissão de doenças como a dengue, as leishmanioses, a febre maculosa, a cólera, a malária. Aponta para a necessidade de estudos interdisciplinares e estratégias políticas integradas.
The present study was effected aiming the verification of the seasonal, spatial and hourly of the phlebotominic species found in the county of Itupeva. Captures were performed fortnightly and 864 sand flies were collected between april/94 and march/95. 81.3% of the captured specimens belonged to 4 species: L. migonei (32.4%), L. whitmani (26.0%), L. intermedia (12.0%) e L. fischeri (10.9%). Such species showed larger densities during the cold and dry season of the year (from april to september/94) and were more active between the second and the fifth hour after twilight. L. migonei predominated almost in all the investigated surroundings being followed by L. whitmani and L. longipalpis in the domestic environments. In conclusion it is thought that in conjunction with L. intermedia, a suspect vector in the State of São Paulo, L. migonei and L. whitmani may have an important role in the transmission of cutaneous leishmaniasis in the area under study.
A dengue é considerada como uma das mais importantes arbovirose que afeta o homem e constitui um sério problema de saúde pública no mundo, especialmente nos países tropicais, onde as condições ambientais principalmente a temperatura, a precipitação, além da umidade relativa, velocidade do vento,
Monitoramento do mosquito
ABSTRACTTDengue is one of the most important arboviruses affecting man and is a serious health problem in tropical areas where climatic conditions are favorable for occurrences of foci of Aedes aegypti. Oviposition traps with added hay infusion were installed at 19 points on the campus of the Federal University of Mato Grosso with the objective of investigating the monthly levels of infestation with the dengue vector and the influence of abiotic factors. The results obtained were compared with the following monthly abiotic data: temperature, relative air humidity and precipitation; and with the number of days for which the traps remained in the field. Rain was the only abiotic factor that influenced the level of infestation of the dengue vector at this location. There were significant differences between the quantities of Aedes aegypti eggs found at different sites within the same study area. The numbers of eggs found at each site over the year did not follow a single distribution pattern.
ResumoO câncer infantojuvenil vem se apresentando como a segunda causa de óbito na população entre 0 e 19 anos no Brasil, atrás apenas dos acidentes. Dentre os fatores ambientais, para além das questões genéticas, estudos epidemiológicos relacionaram exposição a agrotóxicos e tumores da infância, especialmente leucemia. No interior do estado de Mato Grosso, o aumento do cultivo de grãos e exportação vem sendo acompanhado de uso crescente de agrotóxicos. Para analisar a associação entre o uso agrícola de agrotóxico e morbimortalidade por câncer em menores de 20 anos, foi realizado estudo ecológico da média das séries históricas de morbidade (2000)(2001)(2002)(2003)(2004)(2005) e mortalidade (2000)(2001)(2002)(2003)(2004)(2005)(2006) por câncer na faixa etária de 0 a 19 anos e o uso de agrotóxicos nos municípios do estado de Mato Grosso. Observou-se que a média de uso de agrotóxicos nos municípios apresentou associação estatisticamente significante tanto para morbidade (p=0,021), como para mortalidade (p=0,005) por câncer infantojuvenil, com intervalo de confiança de 95%. Os resultados indicam que a exposição aos agrotóxicos está associada à morbimortalidade por câncer na população infantojuvenil. Recomenda-se como medida preventiva para evitar o câncer a redução do uso intencional dos agrotóxicos.Palavras-chave: neoplasias; mortalidade; morbidade; praguicidas.
AbstractCancer in children and adolescents is reported as the second cause of death in the population between 0 and 19 years in Brazil, only behind the accidents. Among environmental factors, in addition to genetic issues, epidemiological studies have linked exposure to pesticides and childhood tumors, especially leukemia. Inside the state of Mato Grosso, the increase in grain cultivation and export has been accompanied by increasing use of pesticides. To analyze the association between the agricultural use of pesticides and cancer morbidity and mortality in children under 20 years, it was conducted ecological study of the average time series of morbidity (2000)(2001)(2002)(2003)(2004)(2005) and mortality (2000)(2001)(2002)(2003)(2004)(2005)(2006) from cancer at the age 0-19 years and the use of pesticides in municipalities in the state of Mato Grosso. It was observed that the average use of pesticides in the counties showed a statistically significant association for both morbidity (p=0.021), as for mortality (p=0.005) for cancer children and adolescents, with 95% confidence interval. The results indicate that exposure to pesticides is associated with morbidity and mortality from cancer in children and adolescents. It is recommended as a preventive measure to prevent cancer to reduce the intentional use of pesticides.
