Objetivo: Avaliar o grau de conhecimento dos acadêmicos de odontologia do Centro Universitário do Norte (UNINORTE-AM) sobre emergências médicas no consultório odontológico e discutir se os alunos estão ou estarão preparados para agir diante de eventuais situações de emergências médicas na prática odontológica enquanto acadêmicos. Material e métodos: No período de setembro a novembro de 2016, foram aplicados questionários, e colhido dados, através de questões objetivas, com respostas do tipo sim/não e múltipla escolha referentes ao diagnóstico e tratamento das principais situações emergenciais, como: síncope/lipotimia, crise hipertensiva, choque anafilático, parada cardiorrespiratória, medicamentos utilizados durante tais intercorrências e a segurança que os acadêmicos possuem diante de uma emergência médica. Resultados: Após a análise da amostra de 157 alunos que responderam ao questionário, verificou-se que 57% dos alunos marcaram de forma errônea as respostas objetivas sobre emergências médicas, ao passo que 43% acertaram as questões. Quando interrogados em relação à segurança frente a situações de emergência médica, 85,36% dos alunos relataram não se sentirem preparados para tal. Quanto a necessidade de disciplina específica de emergência médica na matriz curricular do curso de graduação, o percentual de alunos que responderam sim foi de 96,17%. Conclusão: Evidenciou-se a necessidade de melhor preparação dos futuros profissionais através de uma educação continuada sobre o assunto.
The goal is to show a rare case of Giant Cell Tumor of Bone in the maxillary sinus implicated in a process coincidentally or casually with another type of lesion primarily developed. A 33-year-old male patient attended a surgical service, presenting swelling, obstruction and firm mass externalizing through the right nostril and perceived during 6 months. During the anamnesis, the patient stated to been underwent an incisional biopsy 4 years ago of a tumor with histopathological diagnosis of the Nasal Paraganglioma, however the immunohistochemical study was negative for this tumor. During the Computed Tomography evaluate was observed a hyperdense mass occupying the entire maxillary sinus. In the Nuclear Magnetic Resonance evaluation, it was showed a hypersignal image in the entire maxillary sinus, invading the nasal cavity and portion of skull base. A bone window was performed in the right maxillary sinus and excisional biopsy was made. In the new histopathological examination, the diagnose was consistent with Giant Cell Tumor of Bone, being observed a large number of multinucleated giant cells, some with disorganized nuclei and others similar to Touton giant cells. A large proliferation of xanthomatous-looking cells was also observed without features of malignity. At the 3-year follow-up, the patient reported no complications such as facial paralysis, infection, relapse or spread. The association between lesions occurring in the same location requires further study, possibly implicated in a new model of clinical, microscopic, and genetic disorders. Thus, masses originating from chronic inflammatory tissue may have the potential to transform into GCTB?
Giant Cell Tumor of Bone is an uncommon aggressive benign neoplasm that
frequently affecting the epiphysis of long bones especially around the
knee. This is a singular rare case of GCTB in the right maxillary sinus
implicated in a process coincidentally or casually with another type of
lesion primarily developed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
