RESUMEN

Introdução: No presente trabalho, relatamos um caso de reconstrução do terço proximal do úmero direito e reanimação do cotovelo de um paciente masculino, de 20 anos, vítima de acidente automobilístico, com necrose óssea de 5 cm no terço proximal do úmero e avulsão do bíceps braquial. Métodos: Utilizamos o retalho ósseo da escápula, associado ao retalho miocutâneo do grande dorsal, tendo como pedículo os vasos subescapulares. Resultados: O paciente teve excelente evolução no pós-operatório, apresentando-se, no pós-operatório de 2 meses, com consolidação óssea e iniciando a flexão do cotovelo. Conclusões: Perante a utilização do retalho descrito, concluímos que esta modalidade de retalho se insere no arsenal dos retalhos ósseos de maior segurança nas reconstruções ósseas em geral.

Introduction: We report a case of reconstruction of the proximal third of the right humerus and rehabilitation of the elbow in a 20-year-old male patient who was injured in an automobile accident and developed bone necrosis of 5 cm at the proximal third of the humerus and avulsion of the brachial biceps. Methods: A scapular bone flap was used, together with a latissimus dorsi myocutaneous flap, using subscapular vessels for the pedicle. Results: The patient had excellent postoperative course, presenting in the 2-month postoperative period with bone consolidation and initiation of elbow flexion. Conclusions: This flap modality is a safe and useful option for bone reconstruction.

RESUMEN

UNLABELLED: BACKGROUNGD: previous outcome research in bariatric surgery has to document positive changes in co-morbidities associated with obesity. OBJECTIVE: the study aimed report a description of the impact of bariatric surgery on weight loss and on the resolution of diseases associated with obesity in patients followed up for 12 months in the public health service of São Paulo/Brazil. METHODS: the study was conducted on the data for 598 selected patients with grade III obesity subjected to Rouxen- Y gastric bypass evaluated postoperatively and 6 and 12 months after surgery. Anthropometric, demographic and biochemical data and personal history were determined at each time point. Serum glucose, total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides were determined in the biochemical evaluation. Data were analyzed statistically by the Chi-square test, by ANOVA followed by the Bonferroni post-test and by the Student t-test for independent data, significance set at p < 0.05. RESULTS: weight loss of 45.5 ± 13.7kg (33.5%) was observed during the first year after surgery. Serum glucose, total cholesterol and LDL cholesterol were reduced during the first six months after surgery and the values were maintained up to 12 months, whereas weight and triglycerides were reduced throughout the study period. A reduced prevalence of diabetes mellitus and dyslipidemia was observed after surgery (p < 0.001). CONCLUSIONS: Roux-en-Y gastric bypass is an important procedure for weight loss and control of comorbidities such as diabetes and dyslipidemia at least during the first postoperative year.

Introducción: la investigación de los resultados previa en cirugía bariátrica tiene que documentar los cambios positivos en las comorbilidades asociadas a la obesidad. Objetivo: el objetivo del estudio fue informar de una descripción de los efectos de la cirugía bariátrica sobre la pérdida de peso y en la resolución de enfermedades asociadas con la obesidad en pacientes seguidos durante 12 meses en el servicio de salud pública de São Paulo/Brasil. Métodos: el estudio se realizó con los datos de 598 pacientes seleccionados con obesidad grado III sometidos a bypass gástrico en Y de Roux evaluados antes y 6 y 12 meses después de la cirugía. En cada momento se determinaron la antropometría, los datos demográficos y bioquímicos y la historia personal. La glucosa sérica, el colesterol total, el colesterol LDL, el colesterol HDL y los triglicéridos fueron determinados en la evaluación bioquímica. Los datos fueron analizados estadísticamente por el test de Chi-cuadrado, por ANOVA seguido por el post-test de Bonferroni y por la prueba t de Student para datos independientes; significación fijada en p < 0,05. Resultados: se observó pérdida de peso de 45,5 ± 13,7 kg (33,5%) durante el primer año después de la cirugía. Glucosa sérica, colesterol total y colesterol LDL se redujeron durante los primeros seis meses después de la cirugía y los valores se mantuvieron hasta los 12 meses, mientras que el peso y los triglicéridos se redujeron en todo el período de estudio. Se observó una prevalencia reducida de diabetes mellitus y dislipidemia después de la cirugía (p < 0,001). Conclusiones: el bypass gástrico en Y de Roux es un procedimiento importante para la pérdida de peso y el control de las comorbilidades como la diabetes y la dislipidemia, al menos durante el primer año postoperatorio.

RESUMEN

UNLABELLED: The studies which associated acute kidney injury (AKI) and trauma emerged during the Second World War, and since then we have seen a progressive evolution of healthcare aiming at AKI prevention. However, establishing the risk factors for post-trauma AKI development remains crucial and may help reduce this complication. OBJECTIVE: This study aims at identifying risk factors vis-à-vis the development of AKI in patients with severe trauma and its impact on mortality. This is a retrospective study of 75 patients with severe trauma. Six were taken off because they arrived at the hospital past the point of resuscitation. METHOD: The variables considered were age, gender, trauma severity according to the Injury Severity Score (ISS) and the Glasgow Coma Scale (GCS), trauma mechanism, mean blood pressure upon admission, fluid replacement in the first 24 hours, serum creatinine levels, use of nephrotoxic antibiotics, length of hospital stay, need for ICU admission and mortality. RESULTS: The prevalence of AKI in severe trauma patients was 17.3%, and the factors associated with ARF in this sample were Head Injury and GCS < 10. Mortality, length of hospital stay and the need for ICU were significantly higher in patients who developed AKI. CONCLUSIONS: The identification of these risk factors is of paramount importance for the development of care strategies for patients suffering from severe trauma, for the prevention of acute kidney injury and the associated high mortality.

RESUMEN

Os estudos que relacionaram lesão renal aguda (LRA) e trauma surgiram durante a Segunda Guerra Mundial e, desde então, tem havido progressiva evolução dos cuidados para a prevenção da LRA. Entretanto, a determinação dos fatores de risco para o desenvolvimento de LRA pós-trauma permanece crucial e pode ajudar a reduzir esta complicação. OBJETIVO: Este estudo tem como objetivo identificar os fatores de risco para o desenvolvimento de LRA em pacientes com trauma grave e sua influência na mortalidade. Trata-se de um estudo retrospectivo com 75 pacientes incluídos por apresentarem trauma grave; seis foram excluídos por terem chegado ao hospital sem condições de ressuscitação. MÉTODO: As variáveis estudadas foram: idade, sexo, gravidade do trauma de acordo com Injury Severity Score (ISS) e Escala de Coma de Glasgow (ECG), mecanismo de trauma, pressão arterial média na admissão, reposição volêmica nas primeiras 24h, níveis séricos de creatinina, uso de antibióticos nefrotóxicos, tempo de internação, necessidade de internação em UTI e mortalidade. RESULTADOS: A prevalência de LRA em traumatizados graves foi de 17,3%, sendo que os fatores associados à IRA nessa amostra foram TCE, ECG < 10. A mortalidade, o tempo de internação e a necessidade de UTI foram significativamente maiores nos pacientes que desenvolveram LRA. CONCLUSÕES: A identificação desses fatores de risco é de suma importância para a formulação de estratégias de atendimento aos pacientes vítimas de trauma grave, visando à prevenção da lesão renal aguda e da elevada mortalidade.
