The computed tomographic appearance of volvulus in intestinal malrotation in an adult is presented. The small-bowel loops encircling the superior mesenteric artery create a whirl-like pattern that may be distinctive for this diagnosis.
There are many disease processes, both inflammatory and neoplastic, which can alter the colonic bowel wall. A retrospective study was done on surgically proven cases of colonic disease in which colonic bowel wall abnormalities were identified by computed tomography. Colonic bowel wall thickening was the most common finding, but was nonspecific. Finger-like… (More)
OBJECTIVE We designed a prospective study to determine the frequency of retroperitoneal air after endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy. We sought to elucidate the relationship of retroperitoneal air with endoscopic maneuvers, clinical findings, the length of sphincterotomy, and the time spent during the procedure. We… (More)
The recent identification of antisense RNA in the transcriptomes of many eukaryotes has generated enormous interest. The presence of antisense RNA in Plasmodium falciparum, the causative agent of severe malaria, remains controversial. Elucidation of the mechanism of antisense RNA in P. falciparum synthesis is critical in order to demonstrate the origin and… (More)
Plasma levels of tumor necrosis factor-alpha (TNF-alpha) peak between 2 and 4 h during a 12-h continuous infusion of endotoxin in awake sheep. We hypothesized that a source of this TNF-alpha is the pool of leukocytes that accumulate in the pulmonary circulation. To test this hypothesis, we physiologically monitored six anesthetized sheep during baseline and… (More)
An intramural mass of the second portion of the duodenum proved to be a mucocele of a Brunner gland on excision during cholecystectomy. This entity, although rare, should be included in the differential diagnosis of duodenal mass lesions.
Several patients with lipid storage myopathies have been described, although in most cases the biochemical defect is unclear. A child is reported who presented with severe muscle weakness at age six months. She had lipid storage myopathy due to glutaric aciduria type II. It is probable that her brother died from the same disorder at the age of three months.… (More)
We report two unusual cases of giant sigmoid diverticulum, which is a rare manifestation of diverticular disease. Giant diverticula are 3 to 4 cm or greater in size and are produced by gradual enlargement of an acquired pseudodiverticulum that has had superimposed infection, abscess formation, and healing. For more than 3 years, we have observed and managed… (More)
