- Visceral leishmaniasis caused by Leishmania (Leishmania) amazonensis associated with Hodgkin's lymphoma(2022) PORTO, Victor Bertolo Gomes; CARVALHO, Laina Bubach; BUZO, Bruno Fernando; LITVOC, Marcelo Nobrega; SANTOS, Ana Catharina S.; ROCCI, Rafael Avila; SOARES, Sandra Regina Castro; ZAMPIERI, Ricardo Andrade; DUARTE, Maria Irma Seixas; LINDOSO, Jose Angelo LaulettaVisceral leishmaniasis (VL) is mainly caused by Leishmania (Leishmania) donovani and Leishmania (L.) infantum; however, other Leishmania species have been associated with VL. We report a case of a patient simultaneously diagnosed with VL caused by Leishmania (L.) amazonensis and Hodgkin's lymphoma. After treatment with liposomal amphotericin B and chemotherapy, the patient presented a clinical cure. This case report reinforces the hypothesis that other Leishmania species can cause visceral lesions mainly related to immunosuppression.

- Yellow fever(2018) LITVOC, Marcelo Nobrega; NOVAES, Christina Terra Gallafrio; LOPES, Max Igor Banks FerreiraThe yellow fever (YF) virus is a Flavivirus, transmitted by Haemagogus, Sabethes or Aedes aegypti mosquitoes. The disease is endemic in forest areas in Africa and Latin America leading to epizootics in monkeys that constitute the reservoir of the disease. There are two forms of YF: sylvatic, transmitted accidentally when approaching the forests, and urban, which can be perpetuated by Aedes aegypti. In Brazil, the last case of urban YF occurred in 1942. Since then, there has been an expansion of transmission areas from the North and Midwest regions to the South and Southeast. In 2017, the country faced an important outbreak of the disease mainly in the states of Minas Gerais, Espirito Santo and Rio de Janeiro. In 2018, its reach extended from Minas Gerais toward Sao Paulo. Yellow fever has an incubation period of 3 to 6 days and sudden onset of symptoms with high fever, myalgia, headache, nausea/ vomiting and increased transaminases. The disease ranges from asymptomatic to severe forms. The most serious forms occur in around 15% of those infected, with high lethality rates. These forms lead to renal, hepatic and neurological impairment, and bleeding episodes. Treatment of mild and moderate forms is symptomatic, while severe and malignant forms depend on intensive care. Prevention is achieved by administering the vaccine, which is an effective (immunogenicity at 90-98%) and safe (0.4 severe events per 100,000 doses) measure. In 2018, the first transplants in the world due to YF were performed. There is also an attempt to evaluate the use of active drugs against the virus in order to reduce disease severity.
