A gastric fibrolipoma presenting as acute gastrointestinal hemorrhage.

A 56-year-old woman was admitted to our hospital with upper gastrointestinal hemorrhage from a gastric submucosal tumor that was treated by a laparoscopic technique. Endoscopy and endoscopic ultrasonography (EUS) revealed a 2-cm submucosal tumor located in the posterior wall of the upper gastric body, showing a heterogeneous hyperechoic tumor. A laparoscopic wedge resection of the stomach was performed.

Nonfunctional pituitary macroadenoma manifested as muscular symptoms.

A 75-year-old man with a large pituitary adenoma presented with general muscular weakness, including difficulty in rising in the morning and forceless defecation and urination, and muscular pain, numbness and atrophy in the shoulder, neck and thigh. Testosterone replacement and subsequent resection of the pituitary tumor resulted in resolution of the symptoms. The value of pituitary imaging tests for men with hypogonadotropic hypogonadism is discussed.

Sciatic hernia with an early-stage adenocarcinoma of the appendix: report of a case.

Sciatic hernia and early-stage appendiceal adenocarcinoma are rare disorders. We report herein a case of an early stage of appendiceal adenocarcinoma found incidentally during an operation for sciatic hernia. An 80-year-old woman was admitted to our hospital with abdominal distension.

Evaluation of gastric acid secretion in two patients (each aged over 90 years) with Helicobacter pylori-negative nonsteroidal anti-inflammatory drug-caused duodenal ulcers.

We treated two patients (each aged over 90 years) with Helicobacter pylori-negative nonsteroidal anti-inflammatory drug (NSAID)-caused duodenal ulcers, and had the opportunity to determine gastric acidity by means of 24-h pH monitoring. Endoscopic and histological examination showed no remarkable atrophic change in the gastric mucosa. The gastric pH was low throughout the day and night, and the gastric pH > or = 3 holding time ratio during 24 h was 17.
