    Case report: Mucosal leishmaniasis presenting with nasal septum perforation after almost thirty years
    (American Society of Tropical Medicine and Hygiene, 2018) Rojas-Jaimes, J.; Frischtak, H.L.; Arenas, J.; Lescano, A.G.
    Mucosal leishmaniasis (ML) is associated with progressive tissue destruction and granuloma formation, often after a considerable period of latency from an initial cutaneous infection. We report a case of recurrent epistaxis of 3 years duration and nasopharyngeal obstruction in a woman with treated cutaneous leishmaniasis nearly 30 years before and with no further exposure to Leishmania. Computed tomography revealed nasal septal perforation and histopathology demonstrated chronic inflammation. Microscopy was negative for amastigotes, but molecular testing of nasal mucosa biopsy detected Leishmania (Viannia) braziliensis. The patient underwent 28 days of treatment with IV sodium stibogluconate and her symptoms improved significantly. Sixteen months after treatment, she continues to have episodic epistaxis and detectable parasite load in her nasal lesion. Although ML is known to take years to decades to develop, there are few reported cases in the literature of such a long latency period. This report highlights the importance of considering ML in the differential diagnosis of chronic epistaxis in countries where leishmaniasis is endemic or in immigrants from these countries, even when presentation occurs decades after leaving an endemic region.

    Subdural empyema caused by Peptostreptococcus sp.: a complication of acute pharyngitis
    (Instituto de Medicina Tropical de Sao Paulo, 2017) Rojas-Jaimes, J.; Diaz-Tello, A.; Bazán, C.C.; Kerrigan, M.
    Subdural Empyema (ESD) is the collection of purulent fluid that develops between the exterior “dura mater” layer and the middle “arachnoid mater” layer that covers the brain. ESD can be caused by a primary infection located in the paranasal sinuses. In many aerobic and/or anaerobic bacterial cases, hearing or traumatic processes serve as the causative agent. This report presents pharyngitis in a young girl which later developed into a subdural empyema caused by the bacteria Peptostreptococcus sp. The report emphasizes the correct clinical valuation of pharyngitis as a risk factor for developing subdural empyema in children. © 2017, Instituto de Medicina Tropical de Sao Paulo.
