RESUMO Introdução: As queimaduras encontram-se em quarto lugar como o tipo de trauma mais comum do mundo, gerando um desafio pela gravidade das lesões apresentadas pelos pacientes. Este estudo tem como objetivo rastrear o perfil epidemiológico de pacientes atendidos no ambulatório do Centro de Tratamento de Queimaduras (CTQ) do Hospital Municipal do Tatuapé (HMT/SP). Métodos: Foram analisados os dados obtidos a partir das fichas de atendimento do ambulatório do CTQ do HMT/SP, no período de janeiro de 2019 a janeiro de 2020, utilizando as seguintes variáveis: sexo, idade, agente causal, extensão da queimadura e região acometida. Resultados: Maior predomínio de queimadura no sexo masculino (55,3%). Houve porcentagem maior na população entre 21 a 30 anos (15,9%), seguidos de perto pelos menores de 10 anos (15,8%). O principal agente causador foi escaldo/líquidos aquecidos (56,8%); seguido de queimadura por contato (14,7%), a grande maioria dos pacientes foram acometidos por queimadura de médio porte (90,1%), ou seja, entre 11 e 20% de superfície corpórea queimada e o tórax/abdome a região mais acometida. Conclusão: O perfil epidemiológico demonstrado nesse estudo, mostrou-se compatível, na maioria dos dados, com o perfil encontrado em outros centros especializados em tratamento de queimados.

ABSTRACT Introduction: Burns are in fourth place as the most common type of trauma globally, generating a challenge due to the severity of patients’ injuries. This study investigates the epidemiological profile of patients treated at the Burn Treatment Center (BTC) outpatient clinic of the Hospital Municipal do Tatuapé (HMT/SP). Methods: Data obtained from the outpatient records of the BTC outpatient clinic of the HMT/SP were analyzed from January 2019 to January 2020, using the following variables: gender, age, causal agent, burn extension, and affected region. Results: Higher predominance of burns in males (55.3%). There was a higher percentage in the population between 21 and 30 years (15.9%), followed closely by children under 10 years of age (15.8%). The leading causative agent was scalded/heated liquids (56.8%); followed by contact burn (14.7%), the vast majority of patients were affected by medium-sized burn (90.1%), i.e., between 11 and 20% of the burned body surface and the thorax/abdomen the most affected region. Conclusion: The epidemiological profile demonstrated in this study was compatible, in most data, with the profile found in other centers specialized in treating burns.

ABSTRACT PURPOSE: To compare renal dysfunction after right nephrectomy and ligation of the right renal vein with preservation of kidney. METHODS: Animals' weight, pH, density, protein in urine and histological samples of the kidneys were evaluated. Fifteen female rats (Wistar) were divided into three groups. In the control group, right renal vein dissections were performed. In the second group, the right nephrectomy was performed. In the third group, the right renal vein was ligated and the kidney was preserved. Urine samples were taken before, three and seven days after the procedure. On the seventh postoperative day the kidneys were removed to histopathological study. Analysis by Student's t test was performed. RESULTS: weight loss, alterations of urine pH (p<0.05), in specific gravity, proteinuria (p<0.05) were found in groups 2 and 3; hemorrhagic infarction and edema were found after ligation of the right renal vein; changes in the left kidney were also observed on the seventh day. CONCLUSIONS:
