The presence of auditory middle latency evoked responses allows us to make an evaluation of the peripheral and central auditory system integrity , as well as the nucleus and auditory ways existing until the level of the thalamus-cortical region and primary auditory cortex. Aim: Our objective is to evaluate the presence or not of this numerous peaks, as well as, their latencies and intervals and extend to make a standardizing study. Way of study: Contemporary study of Coorte with transversal cut and the outline was quantitative, descriptive e non experimental. Material and method: Studying several peaks, positives and negatives, caused by the middle latency auditory potentials, in a population of young adults individuals, ranging from 18 to 30 years old, from both genders, with normal hearing. It was used a monoauricular resonant stimulation and a capitation, separately, in both cerebral hemispheres, with surface electrodes. Result: In this research was verified that the analyzed crossings did not present statistically significant results and it was stipulated a pattern from the obtained results. Based on the non-statistical difference found we can affirm that to the Po waves was obtained respectively an average and standard deviation of 12,09 and 1,84; for Na 17,91 and 2,60; for Pa 29, 41 and 5,66; for Nb 41,43 and 8,89; to for 51,44 ms e 12,63 and finally to the interval Na-Pa 11,52 and 4,99. Conclusion: 1-The presence of the defluxions Po, Na, and Pa was verified in all the registers, whereas the defluxions Nb and Pb were absent in only 06 registers. 2-By having these registers, we evaluated that the inveiglement of these defluxions can be used as a reliable method to detect the average latency of the auditory potentials, by electrical generated activities, possibly in sites located in the thalamus-cortical area, evoked by sonorous stimulation. From that point, we establish a pattern of responses for young ones with normal hearing, helping us with future studies in patients with alterations in the hearing system.

The authors concluded that patients with neurological disorders have either wave suppression or enlarged latency periods in relation to normal subjects.

Background: The swine is an essential model for carrying out preclinical research and for teaching complex surgical procedures. There is a lack of experimental models describing anatomical and surgical aspects of total pancreatectomy in the pig. Materials and Methods: The experiments were performed on 10 white male swine weighing 27–33 kg. The animals were premedicated with midazolam (0.4 mg/kg, i.m.) and ketamine (4 mg/kg, i.m.). Anesthesia was induced with propofol (1–2 mg/kg, i.v.) and was maintained with propofol and fentanyl (0.3 mg and 0.1 µg/kg/min, respectively, i.v.). The surgical period ranged from 44 to 77 min. The pancreas anatomy, and the main arterial, venous and pancreatic duct anatomy were assessed. Results: The pancreas anatomy was composed of 3 lobes, the ‘splenic’, ‘duodenal’ and ‘connecting’ lobe which is attached to the anterior portion of the portal vein. The splenic artery and the junction of the splenic vein and portal vein were divided. The left gastric artery was dissected and separated from its origin at the splenic artery. The head of the pancreas is disposed in a C shape. The pancreas was dissected and liberated from the right portion of the portal vein and the infrahepatic vena cava. The pancreas was separated from the duodenum preserving the pancreaticoduodenal artery, then we performed the total pancreatectomy preserving the duodenum, common bile duct and spleen. Conclusion: Total pancreatectomy with duodenum, bile duct and spleen preservation in the pig is feasible and an important instrument for research purposes and teaching surgical technique.

Resumo: Introdução: O cadáver é uma peça insubstituível no aprendizado da anatomia humana, pois permite uma visão tridimensional das estruturas anatômicas. Entretanto, observa-se um cenário de escassez e aumento da demanda das peças cadavéricas nas universidades brasileiras. Logo, diversas instituições, amparadas no artigo 14 da Lei nº 10.406/2002 do Código Civil brasileiro, implementaram programas de doação de corpos interessados em trazer melhorias significativas na qualidade de ensino da disciplina de anatomia. Objetivo: Este estudo teve como objetivo analisar o grau de conhecimento e as perspectivas de uma comunidade universitária a respeito da doação voluntária de corpos cadavéricos para fins educacionais e de pesquisa. Método: Trata-se de um estudo observacional, transversal e prospectivo com abordagem quantitativa e coleta de dados por meio de questionário individual. Os sujeitos incluídos foram os docentes e discentes da Universidade Federal do Maranhão (Ufma), campus Dom Delgado. Os questionários eram relativos à obtenção de informações sobre o conhecimento e a opinião acerca da temática da doação de corpos. Resultado: Obteve-se um total de 264 questionários respondidos, os quais mostraram que 85,65% dos discentes e 87,1% dos docentes tinham conhecimento acerca da possibilidade da doação do próprio corpo. Contudo, observou-se que 94% dos entrevistados não sabiam que procedimentos eram necessários para a doação, e 86% não possuíam conhecimento acerca da legislação que permitia tal prática. Ademais, 27,65% dos participantes estavam aptos a doar o próprio corpo, 33,7% apontaram que não doariam e 38,9% informaram que não tinham opinião formada. O principal motivo apontado para doar foi: “para contribuir com o avanço da educação na área da saúde”, e para não doar: “quero ser enterrado ou cremado”. Conclusão: Existe um alto percentual de indivíduos que não conhecem os meios para realizar a doação de corpos, sendo evidenciado que os participantes apresentam baixa aptidão para doação. Contudo, existe um percentual significativo de indivíduos que não tem opinião formada sobre o assunto, demonstrando que a divulgação dessa temática é um meio para aumentar a adesão a tal prática. É importante realizar o desenvolvimento de programas de doação de corpos para solucionar a problemática.

Introduction: The cadaver is an irreplaceable piece in the learning of human anatomy, allowing a three-dimensional view of anatomical structures. However, there is a scenario of scarcity and increased demand for cadaveric parts in Brazilian universities. Therefore, several institutions, supported by article 14 of Law 10.406/2002 of the Brazilian Civil Code, implemented body donation programs aimed at bringing significant improvements in the teaching quality of the anatomy discipline. Objective: To analyze the level of knowledge and perspectives of a university community regarding the voluntary donation of cadaveric bodies for educational and research purposes. Method: This is an observational, cross-sectional and prospective study with a quantitative approach and data collection through an individual questionnaire. The subjects included in the study were teachers and students from the Federal University of Maranhão, Campus Dom Delgado - UFMA. The questionnaires were related to obtaining information about knowledge and opinions on the topic of body donation. Result: A total of 264 answered questionnaires were obtained, which showed that 85.65% of students and 87.1% of teachers were aware of the possibility of donating their own bodies. However, it was observed that 94% of the interviewees did not know what procedures were necessary for the donation, and 86% did not have knowledge about the legislation that allowed this practice. Furthermore, 27.65% of the participants were able to donate their own body, 33.7% indicated that they would not donate and 38.9% reported that they had no formed opinion. The main reason given for donating was: “to contribute to the advancement of education in the health area”, and for not donating: “I want to be buried or cremated”. Conclusion: There is a high percentage of individuals who do not know how to carry out the donation of their own bodies, being evidenced that the participants have low aptitude for donation. However, there is a significant percentage of individuals who do not have a formed opinion on the subject, demonstrating that the dissemination of this topic is a means to increase adherence to this practice. It is important to carry out the development of body donation programs to solve the problem.
