Hemipelvectomia externa ampliada para tratar adenocarcinoma de sigmóide / Extended external hemipelvectomy for sigmoid adenocarcinoma treatment

Surgery is the most effective way of treating a locally advanced colorectal carcinoma and an extended en bloc resection is necessary to achieve the best overall survival rate. In this rare case, a multi-visceral resection was performed along with the entire lower left limb and left iliac bone for a sigmoid carcinoma. The T4N0M0 (B3) tumor involved the left iliac vessels, left pelvic wall, small bowel and both rectus muscles, besides presenting with a skin fistula. A Hartmann colostomy was also performed. Chemotheraphy was interrupted because of toxicity. The patient is free of disease after 38 months. There are very few cases that describe an extended hemipelvectomy as part of a colorectal carcinoma treatment.

Estudo experimental de 26 ossos semilunares de cadáveres humanos submetidos a teste de compressäo / Experimental study of 26 lunate bones from human cadavers submitted to compression test

Os autores estudaram experimentalmente 26 ossos semilunares de 13 cadáveres frescos, analisando medidas antropométricas e submetendo-os a ensaios de compressäo para verificar sua resistência. Obtiveram valores de resistência variando de 41 a 200kgf, com média de 102,1kgf, e correlacionaram com as medidas antropomêtricas.
