Aspectos epidemiológicos e clínicos da Doença de Chagas aguda no Brasil e na américa Latina / Epidemiological and clinical aspects of acute Chagas Disease in Brazil and Letin America

surgindo em um cenário não habitual, relacionado com a forma de transmissão. Atualmente, a transmissão por via oral envolvendo alimentos contaminados é a principal via de infecção humana, com surtos em toda a América Latina. Entre os sintomas da fase aguda, destacam-se febre prolongada, quase sempre acompanhada de mal-estar, adinamia, cefaleia e perda do apetite, acompanhados de manifestações sistêmicas, tais como adenomegalias e hepatoesplenomegalias. As manifestações cardíacas variam desde quadros assintomáticos até graus variáveis de insuficiência cardíaca aguda ou choque cardiogênico e morte. O tratamento da fase aguda com antiparasitários deve sempre ser instituído, pois existem algumas evidencias de melhor evolução clínica em relatos de casos

Acute Chagas disease shows changes in the epidemiological situation, reappearing in an unusual scenario related to the mode of transmission. Currently, the oral transmission involving contaminated food is the main route of human infection with outbreaks throughout Latin America. Among the symptoms of the acute phase stand out prolonged fever, often accompanied by malaise, asthenia, headache and loss of appetite, accompanied by systemic manifestations such as lymphadenopathy and hepatosplenomegaly. Cardiac manifestations range from asymptomatic clinical statuses to varying degrees of acute heart failure or cardiogenic shock and death. Treatment of acute phase with antiparasitic agents should always be provided, as there is some evidence of better clinical outcome in case reports

Opisthorchiasis in infant remains from the medieval Zeleniy Yar burial ground of XII-XIII centuries AD

We present a paleoparasitological analysis of the medieval Zeleniy Yar burial ground of the XII-XII centuries AD located in the northern part of Western Siberia. Parasite eggs, identified as eggs of Opisthorchis felineus, were found in the samples from the pelvic area of a one year old infant buried at the site. Presence of these eggs in the soil samples from the infant’s abdomen suggests that he/she was infected with opisthorchiasis and imply consumption of undercooked fish. Ethnographic records collected among the population of the northern part of Western Siberia reveal numerous cases of feeding raw fish to their children. Zeleniy Yar case of opisthorchiasis suggests that this dietary custom has persisted from at least medieval times.
