Double transection of complete duodenal circumference after blunt abdominal trauma without other intra-abdominal injuries.

We report a case of a 20-year-old male with isolated complete duodenal transection at two duodenal segments after blunt abdominal trauma. On admission, the patient underwent physical examination, laboratory analysis, abdominal ultrasound and plain abdominal x-ray. Physical examination revealed diffuse and rebound tenderness and extreme rigidity of the abdomen, guarding and decreased bowel sounds.

Bouveret's syndrome--case report.

Background: Bouveret's syndrome is a rare complication of cholecystolithiasis with gastric outlet obstruction caused by a gallstone migrating through a biliogastric or bilioduodenal fistula. Gallstone ileus is mainly treated by surgery, either enterolithotomy or gastrotomy, with some cases being treated by endoscopic extraction.

Case Report: We report on an 80-year-old woman without previous episodes of biliary colic, and known cholecystolithiasis who underwent emergency surgery due to pyloric obstruction caused by a large, 7-cm stone, after failure of endoscopic treatment.

Perforin expression in peripheral blood lymphatic cells of patients subjected to laparoscopic or open cholecystectomy.

Perforin-(P-) related characteristics of cytotoxic T lymphocytes and natural killer cells were investigated in peripheral blood of patients subjected to open (OC; n = 23) or laparoscopic cholecystectomy (LC; n = 21) and healthy controls (n = 20). Blood samples were obtained preoperatively and 24 hours after the surgeries, and the data were correlated with the intensity of cholestasis and concomitant inflammation, determined by functional hepatic tests. Postoperative differences were found to be minimal: OC decreased only the percentage of CD56(+) cells, while LC decreased the fraction of CD8(+)P(+) cells and augmented the mean fluorescence intensity of P in CD56 cells.

Mediastinal necrosis in acute pancreatitis - case report.

Ascites, pseudocyst, necrosis of the retroperitoneal fat tissue and pancreatopleural fistula with left sided pleural effusion may complicate pancreatitis. However, steatonecrosis of the mediastinum and right side pleural effusion are rather rare complications of pancreatitis. We present a case of a patient with alcohol induced pancreatitis.

Swallowing lateralization: the effects of modified dual-task interference.

A modified dual-task paradigm was designed to learn whether swallowing functions are selectively mediated by the left or right hemisphere. Healthy right-handed men (N = 38) were studied using videofluoroscopy to examine continuous straw drinking at baseline and with three interference conditions (silent word repetition, line orientation, finger tapping). Results indicate that activation of both right and left hemispheres can interfere with some swallowing behaviors.
