Pseudomyxoma peritonei occurring after an uneventful 23 years interval from appendectomy.

A 77-year-old male was admitted to our hospital for a bulky abdominal mass. He had a history of appendectomy under the diagnosis of appendiceal rupture 23 years previously. He also had received a radical lung resection for an early lung cancer 2 years earlier in another hospital.

Effects of the cholecystokinin A receptor antagonist loxiglumide on the proliferation and cell cycle time of pancreatic acinar cells in rats.

Objectives: Prior studies have indicated that endogenous or exogenous cholecystokinin (CCK) induces transient acinar cell proliferation at about 24 hours after its stimulation. The aims of the present study were to determine the time point when the administration of the CCK-A-receptor antagonist loxiglumide had its maximal suppressive effect on the proliferation of pancreatic acinar cells and to investigate the effects of loxiglumide on the cell cycle time of pancreatic acinar cells during transient acinar cell proliferation induced by endogenous or exogenous CCK.

Methods: Eight-week-old Wistar rats were divided into the following groups: preadministration of loxiglumide (40 mg/kg) intravenously at 120, 60, and 0 minutes before endogenous CCK stimulation induced by a single oral administration of camostat (50 mg/kg) or exogenous CCK stimulation by a subcutaneous injection of CCK-8 (6 g/kg body weight).

Endoscopic resection for the diagnosis of visceral Kaposi's sarcoma.

Kaposi's sarcoma is an uncommon neoplasm that occasionally involves the gastrointestinal tract in immunosuppressed individuals. Infection with human herpes virus 8 is known to be necessary for developing all forms of Kaposi's sarcoma. We report a renal transplant recipient who developed visceral Kaposi's sarcoma 18 months after the transplantation.

Solid pseudopapillary tumor as a possible cause of acute pancreatitis.

Context: Acute pancreatitis is not commonly seen in the first presentation of pancreatic neoplasms. Solid pseudopapillary tumor as a cause of acute pancreatitis has not yet been reported. This is the first report of acute pancreatitis resulting from solid pseudopapillary tumor.

Increased QT dispersion in patients with alcoholic pancreatitis.

Objectives: Increased dispersion of the QT interval has been proposed to be a novel marker for increased risk of ventricular arrhythmia and sudden cardiac death. This study examined whether QT dispersion is affected in patients with alcoholic pancreatitis.

Methods: We measured the QT interval, corrected QT interval, activation recovery interval, activation time, recovery time, and their respective dispersions in 3 age- and gender-matched groups: patients with alcoholic pancreatitis [age, 58.
