Human lagochilascariasis—A rare helminthic disease

Lagochilascariasis is a parasitic disease caused by a helminth of the order Ascaroidea, genus Lagochilascaris that comprises 6 species, among which only Lagochilascaris minor Leiper, 1909, is implicated in the human form of the disease. It is remarkable that the majority of cases of human lagochilascariasis in the Americas have been reported in Brazil. The natural definitive hosts of this parasite seem to be wild felines and canines. Lagochilascariasis is mostly a chronic human disease that can persist for several years, in which the parasite burrows into the subcutaneous tissues of the neck, paranasal sinuses, and mastoid. L. minor exhibits remarkable ability to migrate through the tissues of its hosts, destroying even bone tissue. Fatal cases have been described in which the parasite was found in the lungs or central nervous system. Treatment is often palliative, with recurrence of lesions. This paper summarizes the main features of the disease and its etiologic agent, including prevalence, life cycle, clinical course, and treatment.

Fronteira, História e Natureza: a construção simbólica do Oeste Brasileiro (1930-1940)

This article aims to present the discourses on the occupation of the Brazilian West in the publications of Cassiano Ricardo, Henrique Silva and Zoroastro Artiaga published in the magazines Cultura Politica (1941-1945), Informacion Goyana (1917-1935), Revista Oeste (1942-1944) and in other works published during the 1940s. Frontier and nature are the analytical categories the article deals with, from an Environmental History perspective. The analysis privileges the scientific and ideological perspectives present in the works studied, which allow for the identification of the symbolic construction of the Brazilian West.
