[A recurrent gastric cancer with peritoneal metastasis 15 years after distal gastrectomy successfully treated with S-1 and weekly intravenous and intraperitoneal injections of Paclitaxel].

Fifteen years after receiving a distal gastrectomy for advanced gastric cancer, a 70-year-old woman was admitted to our hospital because of abdominal fullness due to ascites. Although cytological examination showed adenocarcinoma cells in the fluid, no examination revealed the primary lesion. Peritoneal metastasis was detected via immunohistochemistry using the cell block technique.

[A case of superior mesenteric artery occlusion with ischemic enteritis after transcatheter therapy].

An 84-year-old female was admitted with sudden-onset upper abdominal pain. Contrast-enhanced computed tomography (CECT) revealed complete occlusion of the superior mesenteric artery (SMA). After transcatheter infusion of urokinase, embolic occlusion resolved.

Involvement of IL-17A in the pathogenesis of DSS-induced colitis in mice.

To investigate the etiological implication of IL-17A in inflammatory bowel disease (IBD), dextran sodium sulfate (DSS) was administered to the mice deficient for the IL-17A gene. They showed only faint manifestations of colitis, as revealed by body weight loss, shrinkage in the colon length, serum haptoglobin concentration, and disease activity index. Although the mortality rate of WT mice reached approximately 60%, more than 90% of the IL-17A KO mice survived the DSS treatment.

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.
