Technique to locate the end of an endotracheal tube.

The use of metallic spinal instrumentation in the low-cervical and high-thoracic spine can impede radiographic verification of the position of an endotracheal tube. The method described here may be of value in solving this problem.

Management of abdominal wall clostridial myonecrosis: the role of total gastrointestinal diversion.

We report the successful management of two patients with abdominal wall gas gangrene and emphasize the principles of proximal gastrointestinal diversion and the initial use of 100% fraction of inspired oxygen (FiO2). Each patient lacked an abdominal wall and intractable fistulas developed. Complete diversion of their gastrointestinal tracts at a proximal level facilitated closure of the fistulas and prevented possible peritoneal contamination.

Characterization of a common antigen of colorectal and mucinous ovarian tumors, COTA.

A new colon cancer antigen is reported. It is designated as COTA, Colon-Ovarian Tumor Antigen, because it is found in mucins produced by both tissues during malignancy. The new antigen was identified by making antibodies against human colon cancer tissue in goats.

Massive rectal bleeding of colonic origin: localization of the bleeding site.

Fourteen patients with massive colonic bleeding underwent preoperative evaluation including visceral angiography and/or colonoscopy. Segmental for subtotal colectomy was performed in each case. The freshly excised colonic specimen was opened and washed clean, and the mucosal surface was closely examined by manually compressing the specimen segment by segment in order to detect the minute bleeding site(s), which were then marked with a suture for histologic sectioning.
