RESUMO

Applying a comprehensive diagnostic approach to breast pathology (clinical information, physical exam, state of the art mammography complemented by ultrasonography) 36,396 patients were evaluated. 462 malignancies (40%) were found. 81.2% of carcinomas were clinically occult. 45.2% of the non-palpable lesions were 1 cm or smaller. The yield of carcinomas was 1 every 2.7 biopsies. The preoperative diagnosis of presumptive extensive intraductal component was 85% correct. This information helps to define the excisional limits and upon pathological confirmation select the appropriate surgical therapy: lympectomy vs. mastectomy.

RESUMO

Localization of the pancreatic head for biopsy under fluoroscopy was accomplished using carbon dioxide-producing pills. This technique proved useful when other modalities were unsuccessful. Gas can be a useful contrast agent for localization, has no side effects, and causes little interference with further procedures. A case report is presented.

RESUMO

Common hepatic duct obstruction that results from a gallstone impacted in the cystic duct or fundus of the gallbladder is an uncommon cause of obstructive jaundice and cholangitis. In the literature, the Mirizzi syndrome frequently is used to describe a rare entity consisting of an anatomic variation of the cystic duct or neck of the gallbladder, an impacted gallstone in the cystic duct, and a benign mechanical obstruction of the hepatic duct which causes jaundice and cholangitis. Recently, we saw two patients who had this syndrome. Their case reports, operative management, and a review of the Mirizzi syndrome are discussed in this article.

RESUMO

A simple technique is described for producing enhanced radiographs of excised breast specimens with clinical mammographic equipment. Radiographs of specimens immersed in water are compared to radiographs of the same specimen in air. Using this fluid-balancing technique, visualization of tissue structure is enhanced, particularly when negative-mode Xerox or film is used.

RESUMO

Selective views with negative technique are indicated to exclude or confirm breast tumors. Additional decisive information is obtained to differentiate between benign and malignant lesions. Five case reports are presented.
