Ossifying fibroma is a benign fibro-osseous lesion that occurs most commonly in the mandible of female patients. In rare cases, it affects the nasal cavity. The magnetic resonance imaging features may vary depending on the amount of fibrous and bony tissue in its composition. In these tumors, T2-hypointensity is a feature described in the peripheral ossified areas of the lesion, but it may present diffusely, especially when the degree of ossification is extensive. In this scenario, this particular characteristic on T2-weighted imaging is superimposable to the commonly described appearance of other lesions, such as non-Hodgkin's lymphoma, melanoma, and other sinonasal neoplasms with high cellularity and high nucleocytoplasmic ratio. In the present study, we report a case of ossifying fibroma of the nasal cavity that presented as a diffusely and homogeneously T2-hypointense mass, a finding that may cause difficulty in the differential diagnosis with other expansive sinonasal lesions.

PALAVRAS-CHAVE-Educação Médica.-Docentes Médicos.-Pesquisadores.-Currículo. RESUMOA formação em pesquisa é um elemento importante para o preparo de médicos com perfil crítico-reflexivo. Tendo o docente como pesquisador-orientador, o aluno une teoria e prática, ensino e pesquisa, adquirindo preparação adequada para sua futura ação profissional. Foi realizado um estudo de caso, descritivo, de abordagem quantitativa, onde buscamos identificar, no curso de graduação em Medicina da Universidade Estadual do Ceará, o perfil dos docentes que desenvolvem atividades de pesquisa integradas às didáticas. Para caracterizar esses profissionais foram utilizadas as variáveis: formação na graduação, ciclo em que lecionam as disciplinas e regimes de contratação. Concluímos que a participação em pesquisa é maior entre os docentes não médicos, que lecionam no ciclo básico e que possuem dedicação exclusiva. Acreditamos que a menor participação em pesquisa entre docentes médicos e que atuam no ciclo profissional decorra principalmente da alta proporção desses docentes com vinculação de apenas 20 horas à universidade. A contratação de professores com maiores vínculos e a inserção da pesquisa no currículo principal podem contribuir na formação em pesquisa e, portanto, aprimorar a formação de médicos críticos e reflexivos. ABSTRACTResearch training is important for the preparation of physicians with a critical and reflective profile. Having the teacher as researcher-mentor, the student combines theory and practice, teaching and research, acquiring adequate preparation for their future professional activity. We conducted a descriptive case study, using a quantitative approach, in which we sought to identify the profile of teachers who combine research and learning activities at the Ceará State University School of Medicine. To characterize these professional the following variables were used: undergraduate education; cycle in which their disciplines are taught, and time dedication regime of employment. We concluded that research participation is higher among teachers: with non-medical degrees; who lecture in the basic cycle; and with exclusive dedication. We believe that the lower participation in research among medical and professional cycle teachers results mainly from the high proportion of these teachers with only 20 class hours at the university. Hiring teachers with greater time commitment and integrating research into the core curriculum are factors that could contribute toward improving research training and, therefore, the qualification of critical and analytically minded physicians. na concepção e desenho do estudo, aquisição e análise dos dados, redação inicial e REVISTA BRASILEIRA DE EDUCAÇÃO MÉDICA 36 (1) : 14 -23 ; 2012 23 Pedro Mansueto Melo Souza et al.

Since its beginning in Wuhan, China, in December 2019, the disease caused by COVID-19 has reached more than 27 million confirmed cases and more than 880 thousand deaths worldwide by early September 2020. Although it is known that some of these deaths may have been influenced by the overload of health systems, the world medical literature lacks data on deaths due to COVID-19 in patients who have not received medical assistance. We conducted a retrospective transversal study to report the clinical and epidemiological profile of the first 200 consecutive cases of home deaths without medical assistance caused by COVID-19 diagnosed by verbal autopsy and real-time PCR in samples of postmortem nasopharyngeal swabs, in the state of Ceara, in Northeastern Brazil. The data show a slightly increased prevalence of cases in males (57%) and an average age of 76.8 years. Previous comorbidities were reported in 85.5% of cases, the most common being cardiovascular disease (45%), neurological disease (30%), and diabetes (29%). The main symptoms reported were dyspnea (79%), fever (75.5%), cough (69%), and fatigue (42.5%). The average time between the onset of illness and death was 7.3 days, being statistically shorter in patients who had previous comorbidities (P = 0.0215). This is the first study to evidence the clinical and epidemiological characteristics of COVID-19 home deaths without medical assistance, which may represent a considerable portion of the pandemic burden, especially in the context of health system overload.
