    The objective of the present study was to characterise the floristic and phytosociological composition on a stretch of dense “Terra Firme” rainforest located in the Belo Monte hydroelectric plant area of influence, located in the state of Pará, Brazil. All trees with DAP > 10 cm situated in 75 permanent plots of 1 ha were inventoried. 27,126 individuals trees (361 ind.ha-1), distributed in 59 botanical families, comprising 481 species were observed. The families with the largest number of species were Fabaceae (94), Araceae (65) and Arecaceae (43), comprising 43.7% of total species. The species Alexa grandiflora (4.41), Cenostigma tocantinum (2.50) and Bertholletia excelsa (2.28) showed the highest importance values (IV). The ten species with greater IV are concentrated (22%). The forest community has high species richness and can be classified as diverse age trees, heterogeneous and of medium conservation condition. © 2015, Instituto Internacional de Ecologia.

    A incidência da esquistossomose no Brasil continua alta, atingindo cerca de 10% da população. Desde o primeiro relato da neuroesquistossomose (NE) em nosso país, há mais de 4 décadas, seu comparecimento na literatura nacional tem mostrado acréscimo significativo. O presente trabalho tem como substrato o estudo de 5 casos de NE medular. Estes casos foram avaliados sob o ponto de vista clínico-laboratorial e submetidos a tratamento medicamentoso. Além disso, é nosso propósito incentivar a pesquisa de novos casos, em portadores de quadros sugestivos desta patologia, sobretudo pelos resultados obtidos neste estudo
