The relation between FoxP3⁺ regulatory T cells and fungal density in oral paracoccidioidomycosis: a preliminary study.

Regulatory T (Treg) cells may play an important role in the pathogenesis of paracoccidioidomycosis (PCM), but data on the role of Treg cells in the context of oral PCM are still scarce. The objectives of this study were to investigate the density of FoxP3(+) T regulatory cells in oral PCM and to correlate the results with the density of Paracoccidioides brasiliensis in the lesions. Cases of chronic oral PCM seen between 2000 and 2008 were included in this study.

Ameloblastoma: a clinical and therapeutic analysis on six cases.

Ameloblastomas are odontogenic tumors that are locally invasive and slow-growing. Their etiology is still not well defined, but the forms of treatment have been widely discussed because of the possibility of tumor recurrence and postoperative complications. In this study, six patients who were diagnosed with ameloblastoma in the mandibular region and were treated in the Department of Orthopedics and Traumatology of Hospital das Clínicas, Federal University of Goiás, between 1958 and 1963, were evaluated.

Splenic rupture in dengue hemorrhagic fever: report of a case and review.

Dengue is currently the most important arboviral disease in the world, particularly in tropical countries in which the environmental conditions favor the development and proliferation of the mosquito vector. Dengue hemorrhagic fever presents in two phases: an initial phase, which is characterized by sudden onset of fever and a variety of nonspecific signs and symptoms, and a critical phase, which is characterized by the recovery from fever and development of hemorrhagic symptoms and circulatory insufficiency. This report documents a case of splenic rupture in a patient with dengue hemorrhagic fever who developed hypovolemic shock and subsequently died.
