Metástases pulmonares em crianças: estamos operando desnecessariamente? / Pulmonary metastases in children: are we operating unnecessarily?

RESUMO Objetivo: determinar, em pacientes pediátricos portadores de neoplasias malignas, as características de nódulos pulmonares identificados à tomografia computadorizada, capazes de diferenciar nódulos benignos de metástases. Métodos: estudo retrospectivo de pacientes submetidos a ressecções pulmonares de nódulos diagnosticados como metástases em um período de sete anos. Achados de tomografia e da cirurgia, assim como resultados dos exames anatomopatológicos foram comparados. Resultados: nove pacientes, submetidos a 11 intervenções cirúrgicas, foram estudados. Entre as variáveis estudadas, apenas o tamanho do nódulo, maior do que 12,5mm provou ser estatisticamente significante para predizer malignidade. Conclusão: esse estudo sugere que, entre as características tomográficas de nódulos pulmonares de crianças portadoras de neoplasias malignas, apenas o tamanho da lesão foi preditor de malignidade.

ABSTRACT Objective: to determine, in pediatric patients with malignant neoplasms, the characteristics of pulmonary nodules identified on computed tomography, as well as the possibility of differentiating benign lesions from metastases. Methods: we conducted a retrospective study of patients submitted to pulmonary resections of nodules diagnosed as metastases in a period of seven years. We compared computed tomography and surgery findings, as well as results of anatomopathological examinations. Results: we studied nine patients submitted to 11 surgical interventions. Among the studied variables, only nodule size greater than 12.5mm proved to be statistically significant to predict malignancy. Conclusion: among the tomographic characteristics of pulmonary nodules in children with malignant neoplasms, only the size of the lesion was a predictor of malignancy.

Pé diabético: complicação evitável - Relato de Caso / Diabetic foot: avoidable complication - Case Report

Este relato descreve a evolução de lesão podólica associada ao diabetes mellitus em que a amputação foi a medida tertapêutica necessária. Alerta para a gravidade da evolução do pé diabético, complicação potencialmente prevenível mas muito prevalente no Brasil, com repercussões pessoais e sociais graves, com acometimento de parcela importante de jovens. A importância de sua abordagem requer organização da equipe multiprofissional de saúde e intervenção ativa do médico da Unidade Básica de Saúde não só para o tratamento adequado como para sua prevenção e profilaxia, propiciando ao diabético melhor qualidade de vida.

This report describes the evolution of podic lesion associated with diabetes mellitus in which amputation was the necessary therapeutical measure. Alert for the severity of diabetic foot evolution, a potentially preventable but very prevalent complication in Brazil, with serious personal and social repercussions, involving a significant portion of young people. The importance of its approach requires the organization of the multiprofessional health team and the active intervention of the physician of the Basic Health Unit not only for the appropriate treatment but also for its prevention and prophylaxis, providing diabetics with a better quality of life.

Relationship between the recurrent laryngeal nerve and the inferior thyroid artery: a study in corpses

The anatomical relationship between the recurrent laryngeal nerve (RLN) and the inferior thyroid artery (ITA) was studied in 76 embalmed corpses, 8 females and 68 males. In both sexes, the RLN lay more frequently between branches of the ITA.; it was found in this position in 47.3 percent of male corpses and 42.8 percent of female ones. On the right, RLN was found between branches of the ITA in 49.3 percent of the cases, anterior to it in 38.04 percent, and posterior in 11.26 percent. On the left, the RLN lay between branches of the ITA in 44.45 percent, posterior to the ITA in 37.05 percent, and anterior to it in 18.05 percent of the cases. In 62.68 percent of the cases, the relationship found on one side did not occur again on the opposite side. There was a significant difference (p<0.05) in the distribution of the 3 types of relationships between the RLN and the ITA, on the right and on the left. Racial variations could contribute to an explanation of the differences observed by authors of different countries in the relationship between the RLN and the ITA
