The Baumann Angle: An Analysis from Theory to Practice.

Objective To analyze how the Baumann angle (BA) is affected by inadequate radiographic inclinations. Methods The study was performed from radiographs of the distal humerus of children aged 3 to 10 years. The BA measurements performed by five observers were compared, and each radiograph was evaluated for its quality as "adequate" or "inadequate." The correlation between radiographic quality and the normality of the angles was evaluated. Results Sample was composed of 141 patients, 44% between 3 and 6 years of age and 56% between 7 and 10. We observed the BA between 52.01 and 89.82 degrees, with about 16% of the measurements outside the normal limits of the literature. A total of 33.3% of the evaluated radiographs were classified as "inadequate". On the BA measurements outside the normality parameter, we observed that its proportion was higher among images with inadequate radiographic quality (31.1 vs. 6.2%), and this difference was significant ( p < 0.001). Conclusions The BA is a very variable measurement and, alone, it is unreliable for the evaluation of angular deformities of the pediatric elbow, with radiographic quality proven to be an important causal factor of this variability.

Resumo Objetivo Analisar como o ângulo de Baumann (AB) é afetado por inclinações radiográficas inadequadas. Métodos Estudo realizado a partir de radiografias do úmero distal de crianças de 3 a 10 anos. Foram comparadas as aferições do AB realizadas por cinco observadores, e cada radiografia foi avaliada quanto à sua qualidade em "adequada" ou "inadequada". A correlação entre a qualidade radiográfica e a normalidade dos ângulos foi avaliada. Resultados Amostra composta por 141 pacientes, 44% entre 3 e 6 anos e 56% entre 7 e 10. Observamos AB entre 52,01 e 89,82 graus, tendo cerca de 16% das medidas fora dos limites de normalidade da literatura. Um total de 33,3% das radiografias avaliadas foram classificadas como "inadequadas". Sobre as medidas do AB fora do parâmetro da normalidade, observamos que sua proporção foi maior entre as imagens com qualidade radiográfica inadequada (31,1% vs. 6,2%), tendo essa diferença se mostrado significativa (p< 0,001). Conclusões O AB é uma medida muito variável e, isoladamente, pouco confiável para a avaliação de deformidades angulares do cotovelo pediátrico, tendo a qualidade radiográfica se mostrado um fator causal importante dessa variabilidade.

Análise anatômica da abdominoplastia / Anatomical analysis of abdominoplasty

A abdominoplastia está entre os procedimentos cirúrgicos mais realizados na cirurgia plástica, de forma que muitas variações técnicas têm sido criadas com o objetivo de se reduzirem as complicações e para se obter melhores resultados no contorno abdominal. Nesse contexto, a anatomia da parede abdominal ganha papel de destaque, uma vez que as justificavas em defesa de técnicas, como a abdominoplastia clássica e lipoabdominoplastia, estão atreladas a princípios anatômicos. Isso evidencia a necessidade do domínio da anatomia da região pelo cirurgião plástico, pois, além de entender os motivos de se adotar determinados procedimentos cirúrgicos, o torna mais capacitado de adaptá-los às características anatômicas de cada paciente, além de compreender as alterações morfofuncionais provocadas pela cirurgia. Diante disso, esse trabalho teve o objetivo de buscar na literatura estudos que enfocassem a descrição anatômica da abdominoplastia, tanto clássica quanto de outras variantes, como a lipoabdominoplastia, bem como as explicações anatomofisiopatológicas das principais complicações operatórias inerentes.

Abdominoplasty is a common surgical procedure in plastic surgery. Consequently, several technical variations have been created with the aim of reducing complications and obtaining better results in the abdominal contour. The anatomy of the abdominal region plays an important role in this procedure, since arguments in favor of techniques, such as classic abdominoplasty and lipoabdominoplasty are linked to anatomical principles. This highlights the plastic surgeon's need to have a good knowledge of the anatomy of this region. Not only will this knowledge enable plastic surgeons to understand the reasons for adopting certain surgical procedures, but it will also enable them adapt these procedures to the anatomical characteristics of each patient. In addition, this knowledge will help determine the morphological changes caused by surgery. Therefore, this study aimed to identify studies in the literature focusing on the anatomical description of both classical abdominoplasty and other variants, such as lipoabdominoplasty. It also aimed to discover the anatomical and physiopathological explanations for the major inherent surgical complications.

Trauma leagues: an alternative way to teach trauma surgery to medical students.

OBJECTIVE: to compare the knowledge of medical students between those who are members of the Trauma League (TL) and those from a non-Trauma League (NTL) group of the Federal University of Espírito Santo (UFES). METHODS: cross-sectional, analytical and descriptive study. Two knowledge tests, with 30 questions each, were applied to students from 3rd to 12th period, randomly selecting five students per period, with 50 students in the TL group and 50 in NTL. The questionnaire topics were: pre-hospital care, the mnemonic ABCDE trauma sequence, advanced trauma and imaging. The students' performances were evaluated by graduation-period group: basic (3rd-5th period), intermediary/clinical (6th-8th) and internship (9th-12th). RESULTS: in the first test the average accuracy of the TL group was 20.64 ± 3.17, while for the NTL group, it was 14.76 ± 5.28 (p<0.005). In the second test the average accuracy for the TL group was 21.52 ± 3.64, while for the NTL group, the average was 15.36 ± 29.5 (p<0.005). When divided into graduation periods, it was observed that the TL group showed a higher average across all three groups (p<0.05) in both tests. CONCLUSION: the students who attended the academic league activities have greater knowledge of the issues that are considered relevant to patient trauma care. In all periods of undergraduate academic training, the TL group had greater knowledge of the subject than the NTL group.

OBJETIVO: comparar o conhecimento dos estudantes de Medicina da Liga do Trauma (LT) com os alunos Não Ligantes do Trauma (NLT), sobre os temas do atendimento ao trauma que os acadêmicos possuem maior domínio, avaliando a performance do conhecimento dos dois grupos. MÉTODOS: estudo transversal, analítico, descritivo. Aplicou-se teste de conhecimento para os alunos do terceiro ao 12º período. Desses, foram sorteados cinco acadêmicos de cada período, constituindo dois grupos: 50 no LT e 50 no NLT. Foram aplicados dois testes contento 30 questões para cada prova com os temas: atendimento pré-hospitalar, sequência mnemônica ABCDE do trauma, condutas avançadas e imagem no trauma. Avaliou-se a performance dos estudantes por grupo de períodos da graduação: cadeira básica (3º - 5º período), clínica (6º -8º) e internato (9º - 12º). RESULTADOS: no primeiro teste, a média de acertos do grupo LT foi 20,64±3,17 e 14,76± 5,28 no NLT (p<0,005). No segundo teste, a média do LT foi 21,52±3,64 e 15,36±5,29 no NLT (p<0,005). O grupo LT teve maior média de acerto nas três cadeiras da graduação (p<0,05), nos dois testes. CONCLUSÃO: o grupo LT teve maior média de acerto em relação ao NLT e melhor aproveitamento dos temas estudados em todas as fases do curso médico. .
