Simplified technique to reduce perioral edema in intraoral sagittal split osteotomies.

A simplified technique has been developed for the prevention of the severe perioral edema that is routinely associated with intraoral sagittal split osteotomies of the ascending ramus of the mandible. By the use of gauze sutured through the cheeks in the region of the oral commissures, trauma caused by retraction of instruments is significantly diminished.

NSAID injury to the small intestine.

PURPOSE: To identify the clinical and radiologic findings in patients with diaphragm-like strictures in the small bowel. PATIENTS AND METHODS: We reviewed the histories, radiologic findings, and pathologic findings in two men and two women, all in their sixties, with a history of long-term nonsteroidal antiinflammatory drug (NSAID) or aspirin (ASA) usage and one or more radiologically demonstrated diaphragm-like strictures in the small bowel. RESULTS: Two patients had long histories of NSAID usage, and two of ASA usage. One NSAID user had a long segment of jejunal involvement, and the other three had short segments of duodenal involvement. The ASA users presented with symptoms of esophageal disease, the small bowel lesions were unexpected, and ASA usage was not initially elicited. In one NSAID user and one ASA user, broader strictures with humps rather than diaphragms were also seen producing a lifesaver-like or bagel-like configuration. CONCLUSIONS: Multiple diaphragm-like strictures can occur in NSAID injury and are pathognomonic except in the rare patient with ulcerative enteritis complicating celiac disease. Single or few diaphragm-like strictures can occur in NSAID injury and peptic ulceration. ASA should be considered an NSAID with regard to small-bowel toxicity. A careful medication history is required when an unexplained small bowel abnormality is seen radiologically, and a dedicated small bowel examination is required when NSAID injury is suspected.

Venous intravasation of barium: CT findings.

Portal venous barium and air intravasation occurred during an air contrast enema in a man with ulcerative colitis. Abdominal plain radiography and CT subsequently showed increased hepatic density. Computed tomography also showed colonic intramural and pericolic nodal or venous barium, increased splenic density, and pulmonary arterial barium. The patient's course was benign because little barium embolized beyond the liver into the systemic circulation.

Pancreaticoduodenal tuberculosis simulating metastatic ovarian carcinoma.

A patient from Thailand presented with symptoms suggestive of peptic ulceration. Radiology showed an ulcerated duodenal stricture, a pancreaticoduodenal mass and extensive retroperitoneal lymphadenopathy suggestive of metastatic carcinoma. Tuberculosis was diagnosed only at laparotomy. The incidence of tuberculosis is increasing, and alimentary tuberculosis should be considered in patients from populations at risk presenting with obscure abdominal complaints or unexplained radiologic findings.
