Purpose:To evaluate the minimum inhibitory concentration (MIC) of GTA against these microorganisms and alternative disinfectants for high-level disinfection (HLD). Methods: Reference mycobacteria and clinical M. massiliense strains were included in this study. Active cultures were submitted to susceptibility qualitative tests with GTA dilutions (ranging from 1.5% to 8%), and commercial orthophthaldehyde (OPA) and peracetic acid (PA) -based solutions, during the period of exposure as recommended by National Agency of Sanitary Surveillance for HLD. Results: All reference and M. massiliense non-BRA100 strains, recovered from sputum, were susceptible to any GTA concentration, OPA and PA solutions. M. massiliense BRA100 strains presented MIC of 8% GTA and were susceptible to OPA and PA. Conclusion: M. massiliense BRA100 strain is resistant to high GTA concentrations (up to 7%), which proves that this product is non-effective against specific rapidly growing mycobacteria and should be substituted by OPA or PA -based solutions for HLD. Key words: Mycobacterium Infections. Videolaparoscopy. Disinfection. Glutaraldehyde. RESUMOObjetivo: Avaliar a concentração mínima inibitória (CMI) de GTA frente a M. massiliense e a susceptibilidade a produtos alternativos para desinfecção de alto nível (DAN). Métodos: Cepas de M. massiliense de origem clínica e de referência foram incluídas no estudo. As culturas ativadas foram submetidas a testes qualitativos com diluições de GTA (de 1,5% a 8%) e com soluções comerciais de ortoftaldeído (OPA) ou ácido peracético (PA), utilizando os tempos de exposição recomendados pela Agência Nacional de Vigilância Sanitária para DAN. Resultados: Todas as cepas de referência e M. massiliense não-BRA100, obtida de escarro, foram susceptíveis às concentrações de GTA, e soluções de OPA e PA. As cepas de M. massiliense BRA100 apresentaram CMI de 8% para GTA e foram susceptíveis a OPA e PA. Conclusão: M. massiliense BRA100 é resistente a altas concentrações de GTA (até 7%), o que demonstra que esse composto não é eficaz, e deve ser substituído por OPA ou PA nos processos de DAN.

RESUMO Objetivo: avaliar o benefício de paratireoidectomia em pacientes submetidos à hemodiálise, em relação ao estado nutricional e bioquímico, composição corporal e a qualidade de vida. Métodos: estudo longitudinal envolvendo 28 adultos em programa de hemodiálise, com hiperparatireoidismo secundário grave, avaliados antes e um ano após a cirurgia. Critérios de inclusão: níveis de paratormônio dez vezes superior ao valor de referencia e doença renal crônica em programa de hemodiálise. O índice de massa corporal foi utilizado para classificação do estado nutricional. A bioimpedância elétrica para avaliação da composição corporal. A análise bioquímica incluiu dosagem de lipídios e marcadores do metabolismo ósseo. A qualidade de vida foi avaliada pelo questionário SF36 (Short Form Health Survey). Todos os pacientes foram submetidos à paratireoidectomia total com implante em antebraço. Resultados: houve ganho significativo de peso corporal (61,7 vs 66,0 kg; p<0,001), da massa celular corporal (22,0 vs 24,5 kg/m2; p=0,05) e da qualidade de vida (p=0,001) após a cirurgia. Com relação ao metabolismo ósseo, PTH intacto, cálcio, fósforo e fosfatase alcalina, se estabilizaram e houve melhora em parâmetros bioquímicos, tais como albumina e hemoglobina. Conclusão: a paratireoidectomia melhora a sobrevida em pacientes de hemodiálise e está associada a aumento de peso, ganho de massa óssea e melhoria na qualidade de vida.

PURPOSE: Analyze the morphological and structural outcomes of a patch of expanded polytetrafluoroethylene in the treatment of an iatrogenic injury of the common bile duct. METHODS: In Group 1 (Sham), 7 dogs underwent 3 laparotomies with intervals of 30 days between them. In Group 2, 10 dogs underwent transient common bile duct obstruction. After 30 days, this biliary occlusion was undone and a patch of expanded polytetrafluoroethylene replaced a fragment removed from the duct's wall. Thirty days after this last surgery, cholangiographic assessment of prosthesis patency and macro and microscopic evaluation of the biliary tract were performed. Daily clinical inspection completed the study outcomes. The Wilcoxon non-parametric test was used for statistical analysis. RESULTS: In all dogs enlargement of the biliary tree diameter was observed 30 and 60 days after the first surgical procedure. Partial adhesion of the patch to the common bile duct as a free luminal foreign body was found in 6 dogs. The prosthesis was completely integrated to surrounding tissue in the remaining four. CONCLUSION: Although a feasible option for the treatment of biliary duct iatrogenic lesions, the expanded polytetrafluoroethylene prosthesis must be used with caution considering the potential risks for complications.

Arq Bras Endocrinol Metab vol 49 nº 2 Abril 2005 314 RESUMOO hiperparatireoidismo primário (HPP) é uma doença incomum na infân-cia e na adolescência. A associação de HPP e epifisiólise de cabeça do fêmur é rara, tendo sido descritos apenas quatro casos na literatura. Relatamos um caso de HPP por adenoma de paratireóide, com dores e inúmeras deformidades ósseas, associado a epifisiólise de cabeça do fêmur em um jovem de 18 anos. A análise laboratorial mostrou cálcio de 13,7mg/dL, paratormônio de 1.524pg/mL e fosfatase alcalina de 3.449U/L. As deformidades foram decorrentes de diagnóstico tardio e possivelmente pelo fato de a doença ter ocorrido na fase de estirão puberal. A combinação de vários fatores metabólicos e mecânicos provavelmente contribuiu para esta associação. O paciente foi submetido à remoção cirúrgica do adenoma, que costuma ser acompanhada por resolução pronta da epifisiólise. Desta forma, foi optado por conduta expectante quanto à epifisiólise da cabeça do fêmur, em consonância com a literatura. Houve melhora das dores ósseas e normalização dos níveis de cálcio e de paratormônio. ABSTRACT Primary Hyperparathyroidism Associated to Slipped Capital Femoral Epiphysis in a Teenager.Primary hyperparathyroidism (PHP) is an uncommon disease in children and adolescents. The association between PHP and slipped capital femoral epiphysis is rare, and so far only four cases have been reported in the literature. Herein, we report a case of PHP due to a parathyroid adenoma, with several painful skeletal deformities and associated with slipped capital femoral epiphysis in an 18-year-old male patient. Laboratory evaluation showed: calcium of 13.6mg/dL, parathyroid hormone of 1,524pg/mL and alkaline phosphatase of 3,449U/L. Deformities were caused by late diagnosis during the growth spurt, and this association is the result of combinations between metabolic and mechanical factors. The patient underwent parathyroidectomy and, in agreement with the literature, since the removal of the adenoma is followed by prompt resolution of the slipped capital femoral epiphysis we decided for a conservative approach. We observed improvement of the pain and normalization of calcium and parathyroid hormone levels.

Background: Few centers in Brazil perform parathyroidectomy (PTX) for recalcitrant secondary hyperparathyroidism (SHPT) generating a long queue. There is little data regarding prioritize criteria besides chronological order and survival. Objectives: To determine the difference of clinical and laboratory factors between PTX patients and those who remained in the line despite the need for surgery and their survival. Methods: A retrospective cohort study was conducted in a quaternary hospital in Brazil, where 43 patients with PTX indication due to severe SHPT were followed from 2009 to 2016. While 31 patients underwent PTX, 12 remained in the queue. Data on clinical and laboratory factors were collected for comparison and Kaplan–Meier and Cox regression survival analysis were used. Results: PTX group was younger (40.9 vs. 49.3 years, p = .03), had higher PTH levels (2578 vs. 1937 pg/ml, p = .01) and higher CaxP product (62 vs. 47.5, p = .02). There were no percentage differences between groups of fractures, calciphylaxis and other complications due to SHPT. Patients who were not operated had a worst overall survival (5 y 62.2% vs. 96.7%, p = .04) with a HR for death of 8.08 ( p = .07, PTX as a TVC). Other variables associated with decreased survival included a history of previous myocardial infarction (HR: 10.4, p = .01) and age per additional year (HR: 1.09, p = .02). Conclusions: Patients with severe SHPT are at increased risk of death while waiting for PTX. Clinical events like fracture were not used to prioritize patients beyond consecutive order. Therefore, optimizing priority criteria for PTX may result in improved survival in this population.

Introduction: the attraction of women by Surgery has always existed. Although Surgery has been considered a specialty for men, several women chose it, despite gender bias issues that have persisted over many years. Several obstacles have impacted the practice of women surgeons, leading them to abandon the profession, while others, perhaps bearers of a stronger spirit, managed to overcome them, and won. Objective: to assess the rates of perception of harassment against female surgeons as a cause of difficulty and negative feelings related to the specialty. Methods: we conducted a quantitative and qualitative (personal accounts) research through a questionnaire via Google Forms® sent to all women surgeons registered in the Brazilian College of Surgeons and in a WhatsApp women surgeons’ groups. The qualitative analysis was made with the Wordle® app. Results: from 821 questionnaires sent, we obtained 232 responses (28.2%). Harassment perception during training was 49.1% (n=114). From the women surgeons who perceived harassment, 56.1% reported having undergone different training than expected, with statistical significance (p<0.001). The question of having been treated differently due to being a woman also had an impact on harassment perception (77.2% harassed vs 47.5%; p<0.001). Physical (42.1% vs 6.8%) and emotional (92.1% vs 39.8%) threats were also different between groups. Conclusion: women surgeons still report great harassment perception, both moral and sexual, which impacts their feelings about the specialty.

Introduction: Confronting the COVID-19 pandemic involves actions in the scope of information, especially in combating false content disseminated by social media. In this sense, medical students, including those belonging to a Trauma and Emergency Academic League, have mobilized to create a media campaign in order to disseminate information about SARS-CoV-2’s aspects to the population. The objective of this work was to report the contribution of the league members to the campaign developed to disseminate reliable scientific content based on simple and objective language about COVID-19. Methodology: A campaign was organized by second to the sixth-year medical students, members of 15 university academic leagues, with the aim to use social media as an information tool for health educational practice. Results: The students from the Trauma and Emergency Academic League made a total of 6 posts on Instagram, using the league’s and the campaign’s accounts. Those posts obtained a total of 1983 views and had the purposed of reaching the general population. The information provided was about self-medication and its risks or benefits, preventive measures against COVID-19 and how to make and use homemade masks. Among the public that accessed the campaign’s profile on Instagram, 70% were women and 80% were between 18 and 34 years old. Discussion: With the reported activities, league students described acquiring knowledge about COVID-19, in addition to teamwork experience and contribution to the fight against the pandemic through the materials production and its dissemination to the population. It allowed innovation in learning and in the access to knowledge, as the pandemic imposed new health-related educational challenges. However, it is noticed that there is a limitation in the posts scope, as they have mostly reached a specific age group. Conclusion: The proper internet usage is essential to combat misleading information in the pandemic context. Therefore, the online dissemination of reliable information with the intent to reach a larger audience indicates academic commitment, especially to social responsibility.
