Purpose: To evaluate the impact of submersion of the microsurgical anastomosis suture area using saline (0.9% NaCl) in an experimental laboratory during the training of medical students and resident physicians. Methods: Wistar rats (n = 10) were selected to have the two femoral arteries sectioned and anastomosed end-to-end under optical magnification. They were randomly divided, so that on one side suturing was performed under submersion with saline, and the contralateral side was kept dry during the procedure. The surgical times, as well as the patency within 30 min and 72 h of the procedure, were evaluated. Results: Six male Wistar rats survived the surgical anesthetic procedure, with the average initial weight of 243.3 g and the average artery diameter of 0.86 mm, with average time of 15.67 min for the submerged technique and 20.50 min for the dry technique (p = 0.03). The failure rates were 17 and 50% for the submerged group and the dry one, respectively (p = 0.62). Conclusion: Submerged microvascular suture does not compromise the patency of the vessel or increase the time of anastomosis. Therefore, it is a strategy that can be applied by the surgeon according to his/her technical preferences.

Soccer is one of the most popular sports in the world. Despite the concept that soccer is not a violent game, it can lead to several injuries in amateur and professional settings, including facial fractures. Previous studies of facial fractures in soccer were all retrospective and, to date, no prospective studies are available in the literature.The authors performed a comprehensive literature search using the terms ''soccer'' AND ''facial fracture'' OR ''craniofacial fracture'' and ''football'' AND ''facial fracture'' OR ''craniofacial fracture'' and retrieved 693 articles. After applying inclusion and exclusion criteria, 11 articles were included in the present study.A total of 647 patients had suffered facial trauma, with a maleto-female ratio of 63.7:1. The patients' mean age was 27.3 years.The articles reported 670 fractures as follows: 219 (32.7%) in the zygoma, 197 (29.4%) in the nasal bone, 153 (23.6%) in the mandibula, 54 (8.0%) in the orbital wall, 12 (1.8%) in the frontal sinus, 10 (1.5%) in the alveolar bone, 3 (0.4%) in the maxilla, 3 (0.4%) in a Le Fort pattern, and 1 (0.1%) in a naso-orbito-ethmoid (NOE) pattern.Sports are a frequent cause of maxillofacial trauma and are responsible for 9.2% to 33.2% of such injuries. Soccer is a contact sport more associated with lower-limb injuries, but with a significant rate of facial fractures. As soccer is a popular sport played without facial protection and involving high-intensity movements and contact, the prevention of facial fractures related to this sport is crucial to improve the players' safety.

Burns cause greater morbidity and mortality in older patients owing to the physiological changes and functional status declines with age. We sought to characterize the epidemiology of burn injuries in the patient population aged over eighty years. A retrospective analysis of all patients aged >80 years admitted to a tertiary burn center in Brazil over a 10-year period was conducted. Multiple parameters including comorbidities, body surface area(BSA) burned, intensive care unit(ICU) admissions, inhalation injury and revised Baux score were analyzed to assess association with mortality. 26 patients were identified. The overall mortality rate was 42.3%. The mortality rate increased with the TBSA, with 100% mortality at >20% total BSA involvement(p<0.001). Inhalation injury occurred in 3(11.5%) patients, all of whom suffered mortality(p<0.001). ICU admission was necessary for 14(53.8%) patients, out of which 11(78.6%) did not survive(p<0.001). The revised Baux score had a significant impact on the mortality, with higher values among patients who did not survive(89.2 ± 6.2 versus 110.7 ± 17.9,p < 0.001). Burns cause high mortality in the octogenarian and nonagenarian populations. It is important to stratify patients at high risk, institute prompt treatment and discuss goals of care early on for optimal patient outcomes.

RESUMO Introdução: obesidade é uma das doenças mais comuns do mundo e a cirurgia bariátrica é o tratamento mais eficaz até o momento. Um dos impactos negativos do procedimento é o dismorfismo corporal causado pelo excesso cutâneo. No Brasil, o Sistema Único de Saúde (SUS) promove cirurgia de contorno corporal para tratar pacientes com perda ponderal maciça desde 2007. Este artigo tem como objetivo descrever a abordagem do SUS para pacientes pós-bariátricos através de análise do banco de dados do próprio sistema. Métodos: foi realizada pesquisa no banco de dados do SUS para procedimentos em pós-bariátricos entre 2007 e 2021. As variáveis analisadas foram localização geográfica, ano, tempo médio de internação, morte e taxa de mortalidade. Também analisamos o número de procedimentos bariátricos realizados no mesmo período. Análise estatística foi realizada utilizando os testes t de Student e do Qui-Quadrado, considerando valor p<0,5 como significante. Resultados: um total de 12.717 procedimentos de cirurgia plástica foram realizados em pacientes pós-bariátricos, com prevalência nacional de 13,8%. Dermolipectomia foi o procedimento mais realizado, com um total de 6.719. Nos anos de 2020 e 2021 houve um decréscimo de 64,3 e 70,9% no total de cirurgias, respectivamente (p<0,001). Procedimentos bariátricos tiveram maior número total e taxa de crescimento maiores do que cirurgia pós-bariátricas (p<0,001), totalizando 93.589 cirurgias. Conclusões: houve um número significativo de cirurgias de contorno corporal no Brasil, embora com baixa prevalência. Dermolipectomia foi o procedimento mais realizado. Notamos impacto significativo da pandemia Sars-CoV-2 no total de procedimentos realizados.
