Background: Based on relation of pathological effects of stress on the body and its reflex on blood pressure, the high level of stress undergone by medical students becomes a concern about quality of medical training and its health. The aim is to verify the possible influence of stress during exam periods on the blood pressure of medical students. Method: The systemic arterial pressure (SAP) of 109 medical students of an institution was measured and analyzed in the period from March to September 2016, using the standardization recommended by the American Heart Association, in 3 time intervals: school holidays, classes without exams, and classes with exams. Results: The authors verified that the systolic arterial pressure and cardiac frequency values checked on exam days were statistically higher (mean of 121.60 mmHg and 85 bpm, respectively) than when measured on class days or during vacations. Whereas the systolic arterial pressure and cardiac frequency values measured on class days were significantly lower than those on the other days (mean of 112.75 mmHg and 74.86 bpm, respectively). Conclusion: The authors statistically verified that stress during exam periods had an influence on the arterial blood pressure of medical students, bringing into focus the need for teaching institutions to provide these students with psychosocial and pedagogical support.
Atherosclerosis is a pathology of great importance worldwide, because of its direct relationship with cerebrovascular events
RESUMOA aterosclerose representa uma patologia de grande importância mundial devido à relação direta com as doenças cerebrovaculares, resultando em altos índices de morbimortalidade. A possibilidade de identificação destas placas ateromatosas através da radiografia panorâmica está consolidada na literatura, sendo também relatadas suas limitações. Com intutito de possibilitar um diagnóstico diferencial de ateromas na prática odontológica, a Projeção de Manzi consiste numa técnica ântero-posterior que possibilita uma visualização sem sobreposições do trajeto carotídeo. O presente estudo tem por objetivo relatar um caso clínico demonstrando as possibilidades diagnósticas dos exames odontológicos na detecção de ateromas calcificados na artéria carótida.Termos de indexação: Aterosclerose. Artérias carótidas. Radiografia panorâmica.
Introdução: O laser em baixa intensidade apresenta propriedades que podem ser efetivas no tratamento endodôntico, como a capacidade reparadora, a atuação antimicrobiana e o auxílio à proliferação celular. Objetivo: Descrever, por meio do relato de um caso clínico, a ação do laser em baixa intensidade como coadjuvante na reparação óssea de uma perfuração radicular e lesão perirradicular em um elemento dentário com canais tratados, sendo realizado retratamento endodôntico apenas do canal mesiovestibular, utilizando-se hidróxido de cálcio como medicação intracanal e laser em baixa intensidade. Os demais canais não foram submetidos a retratamento, apesar de apresentarem lesão perirradicular. Resultados: O laser em baixa intensidade mostrou-se efetivo como auxiliar no processo de reparação óssea restituindo, ad integrum, o osso interradicular e as lesões perirradiculares das raízes mesial e distal após acompanhamento de 12 anos. Conclusões: O laser em baixa intensidade pode ser utilizado como coadjuvante ao tratamento de perfurações, demonstrando sucesso em longo prazo.
Introduction. Early diagnosis of calcified atheromas may decrease morbidity and mortality caused by brain and cardiovascular diseases, in which atherosclerosis is the main etiological factor of these pathologies. Dental examinations with the aim of detecting this pathology have been in progress since 1981, such as panoramic radiography, considered the most widely studied method for this diagnosis. However, some limitations of this exam have been reported with reference to inability to visualize the cervical region and difficulty of establishing a precise diagnosis because of many structures and calcifications that have similar radiographic characteristics. Case Report. The present study to describe a dental radiographic technique for establishing the differential diagnosis of calcified atheromas regarding other calcifications and reporting 3 clinical cases that demonstrate its effectiveness in different clinical situations. Discussion. Manzi Projection can promote a differential diagnosis of calcified atheromas in dental practice and consequently subsidize the clinician for referring the patient to the physician.
