ABSTRACT

Resumo: Introdução: Em janeiro de 2020, a OMS reconheceu a pandemia do novo coronavírus no mundo, chegando os casos ao Brasil em fevereiro e ao Acre em março. Uma das respostas para enfrentamento da pandemia no estado foi o telemonitoramento dos casos suspeitos e confirmados de Covid-19, que se viabilizou a partir da parceria entre o Núcleo Telessaúde Acre, as Secretarias de Saúde e os cursos Medicina da Universidade Federal do Acre (Ufac) e do Centro Universitário Uninorte. O objetivo do artigo é relatar a experiência do projeto de ensino de apoio ao telemonitoramento dos casos de covid-19 em Rio Branco. Relato de experiência: O telemonitoramento tem sido realizado por uma equipe composta de 210 alunos de Medicina dos últimos períodos do curso e por um grupo de oito professores. Atenta às necessidades de fortalecimento das ações de enfrentamento do novo coronavírus, a Pró-Reitoria de Graduação da Ufac lançou um edital para projetos de ensino que pudessem cumprir esse papel social por meio da sistematização de conhecimentos sobre o tema. Discussão: A partir daí, o projeto foi executado através de reuniões virtuais sistemáticas da equipe executora do telemonitoramento pela plataforma Zoom, com discussões dos casos acompanhados, de rodas de conversa com especialistas sobre temas clínicos específicos, apresentação de artigos, discussão de dados epidemiológicos e aulas expositivas sobre a Covid-19. Além disso, têm sido articulados trabalhos de conclusão de curso a partir dos dados trabalhados na estratégia. Conclusão: Apesar do desafio que é trabalhar a partir do ensino remoto, o projeto tem contribuído de maneira substancial para o aprofundamento dos conhecimentos sobre a pandemia de Covid-19 e para o acompanhamento dos casos em Rio Branco.


Abstract: Introduction: In January 2020, the WHO recognized the new Coronavirus pandemic, reaching Brazil in February, and the state of Acre in March. One of the actions employed to tackle the pandemic in Acre is the telemonitoring of suspected and confirmed Covid-19 cases, enabled though a partnership between the Acre Telehealth Center, the Health Departments and the two local medical courses. The purpose of this article is to report the experience of the teaching project to support telemonitoring of Covid-19 cases in Rio Branco. Experience report: The telemonitoring was performed by a team of 210 final year medical student and a group of eight professors. Aware of the need to strengthen actions to tackle the new Coronavirus, the UFAC central administration issued a public notice for teaching projects that could fulfill this social role by systematizing knowledge on the subject. Discussion: The project has been carried out through systematic virtual meetings of the telemonitoring executive team on the Zoom platform, with discussions of the monitored cases, discussions with specialists on specific clinical topics, the presentation of articles, discussion of epidemiological data and lectures on Covid-19. Furthermore, course conclusion papers have been developed based on the telemonitoring data. Conclusion: Despite the challenge of working through distance learning, the project has contributed substantially to deepening knowledge about the Covid-19 pandemic and to monitoring cases in Rio Branco.

ABSTRACT

Abstract Objective: To evaluate liver lesions, in accordance with the LI-RADS classification, using contrast-enhanced multiphase dynamic computed tomography in patients with hepatitis B, coinfected or not with hepatitis D, or with chronic hepatitis C, as well as to determine the level of agreement between radiologists. Materials and Methods: We evaluated 38 patients with hepatitis B, coinfected or not with hepatitis D, or with chronic hepatitis C, all of whom underwent contrast-enhanced multiphase dynamic computed tomography. For each examination, two radiologists selected up to three hepatic lesions, categorizing them in accordance with the LI-RADS classification and evaluating signs of chronic liver disease and portal hypertension. To determine the level of agreement between radiologists, we calculated the kappa statistic (κ) . Results: Radiologist 1 and radiologist 2 selected 56 and 48 liver lesions, respectively. According to radiologist 1 and radiologist 2, respectively, 27 (71%) and 23 (61%) of the 38 patients had at least one liver lesion; 13 (34%) and 12 (32%) had a LI-RADS 5 lesion (κ = 0.821); 19 (50%) and 16 (42%) had a hypervascular lesion (κ = 0.668); and 30 (79%) and 24 (63%) had splenomegaly (κ = 0.503). Both radiologists identified chronic liver disease in 31 (82%) of the patients (κ = 1.00). Conclusion: Lesions categorized as LI-RADS 5 were detected in approximately 32% of the patients, with almost perfect agreement between the radiologists. The level of agreement was substantial or moderate for the other LI-RADS categories.


Resumo Objetivo: Avaliar lesões hepáticas de acordo com a classificação LI-RADS nas tomografias computadorizadas de pacientes com hepatite B, co-infectados ou não com vírus delta, e com hepatite C crõnica, e o grau de concordância entre os radiologistas. Materiais e Métodos: Foram incluídos 38 pacientes com hepatite B, co-infectados ou não com vírus delta, e/ou com hepatite C crônica, que realizaram tomografia computadorizada. Dois radiologistas selecionaram até três lesões hepáticas classificadas pelo LI-RADS e avaliaram sinais de hepatopatia crônica e de hipertensão portal. Foi utilizado o teste kappa (κ) para avaliar o grau de concordância entre os radiologistas. Resultados: Foram selecionadas 56 observações pelo radiologista 1 e 48 pelo radiologista 2. Verificou-se que 71% e 61% dos pacientes apresentaram pelo menos uma observação hepática, segundo o radiologista 1 e o radiologista 2, respectivamente. Dos 38 pacientes, 13 (34%), segundo o radiologista 1, e 12 (32%), segundo o radiologista 2, apresentaram observações LI-RADS 5 (κ = 0,821). Hipervascularização foi detectada em 50% e 42% dos pacientes (κ = 0,668), esplenomegalia em 79% e 63% (κ = 0,503) e sinais de hepatopatia crônica em 82% (κ = 1,00), segundo o radiologista 1 e o radiologista 2, respectivamente. Conclusão: Detectaram-se, aproximadamente, 32% de observações LI-RADS 5 nos pacientes, com concordância quase perfeita entre os radiologistas. Houve concordância substancial/moderada entre as demais categorias LI-RADS.

ABSTRACT

Abstract Purpose To develop 3D anatomical models, and corresponding radiographs, of canine jaw fractures. Methods A base model was generated from a mandibular bone scan. With this model it was possible to perform fracture planning according to the anatomical location. Results The 3D base model of the canine mandible was similar in conformation to the natural bone, demonstrating structures such as canine tooth crowns, premolars and molars, mental foramina, body of the mandible, ramus of the mandible, masseteric fossa, the coronoid process, condylar process, and angular process. It was not possible to obtain detail of the crown of the incisor teeth, mandibular symphysis, and the medullary channel. Production of the 3D CJF model took 10.6 h, used 150.1 g of filament (ABS) and cost US$5.83. Conclusion The 3D canine jaw fractures models, which reproduced natural canine jaw fractures, and their respective radiographic images, are a possible source of educational material for the teaching of veterinary medicine.
