[Tetanus: an immunopreventable disease].

Tetanus is an infectious disease caused by a ubiquitous bacterium Clostridium tetani, that synthesizes and releasesa potent neurotoxin under anaerobic conditions, which is responsible for the clinical manifestations. As it is found in soil contaminated with animal and human excreta, it is difficult to eradicate but it may be prevented by immunization. Immunization rate has decreased in the last years, especially during the COVID-19 pandemic.

[Chagas disease in the central nervous system in patient infected with HIV: diagnostic and therapeutic difficulties].

Chagas disease (ChD), caused by the protozoan Trypanosoma cruzi, is an endemic anthropozoonosis in Latin America, linked to deficients socio-economic and cultural aspects and is considered one of the neglected tropical diseases. We report a fatal case of Chagas disease reactivation with central nervous system involvement in a patient with HIV infection, whose diagnosis was confirmed by positive PCR (polymerase chain reaction) test of blood, with treatment response efficiency with benznidazol and management and etiologic treatment was difficult due to limited number of antitrypanosomal drugs and the occurrence of frequent and serious adverse effects.
