1/534. Pill-induced gastric injury.

    Pill-induced esophageal injury is a well described clinical entity. In contrast, pill-induced gastric injury has not been well characterized. In this report, we describe two patients with acute gastric ulcers due to pill ingestion and review the available literature on pill-induced gastric injury. The first patient presented with upper gastrointestinal hemorrhage and was found to have a large gastric ulcer with multiple potassium chloride pills in the ulcer crater. The second patient presented with odynophagia and endoscopy revealed doxycycline-induced esophageal and gastric injury. To our knowledge, this is the first case report of doxycycline-induced gastric ulcer. ( info)

2/534. A case of cimetidine-induced acute tubulointerstitial nephritis associated with antineutrophil cytoplasmic antibody.

    We present a case of acute tubulointerstitial nephritis (ATIN) that developed in a 63-year-old man who had been taking cimetidine for treatment of a gastric ulcer. The constellation of clinical, laboratory, and histopathologic findings suggested drug-induced ATIN. Of interest, the patient had antineutrophil cytoplasmic antibody (ANCA) in his sera, reactive with myeloperoxidase, elastase, and lactoferrin. Prominent renal histological features included marked plasmacyte infiltration into the renal interstitium. Withdrawal of cimetidine resulted in complete resolution of renal findings, and the titers of ANCA concomitantly declined. Thus, cimetidine may have played a causative role in the development of ANCA-associated ATIN. ( info)

3/534. pneumoperitoneum caused by a perforated peptic ulcer in a peritoneal dialysis patient: difficulty in diagnosis.

    peritonitis due to viscus perforation in peritoneal dialysis (PD) patients can be catastrophic. We describe the first reported case of perforated peptic ulcer (PPU) in a PD patient. This 78-year-old man presented with a 1-day history of mild abdominal pain. He had been receiving nocturnal intermittent PD for 2 years and had ischemic heart disease and cirrhosis of the liver. pneumoperitoneum and peritonitis were documented, but the symptoms were mild. The "board-like abdomen" sign was not noted. air inflation and contrast radiography indicated a perforation in the upper gastrointestinal tract, and laparotomy disclosed a perforation in the prepyloric great curvature. Unfortunately, the patient died during surgery. This case illustrates that the "board-like abdomen" sign may be absent in PD patients with PPU because of dilution of gastric acid by the dialysate. Free air in the abdomen, although suggestive of PPU, is also not uncommon in PD patients without viscus perforation. Because PD has to be discontinued after laparotomy and exploratory laparotomy may be fatal in high-risk patients, other diagnostic methods should be used to confirm viscus perforation before surgery. PPU, which can be proved by air inflation and contrast radiography, should be suspected in PD patients with pneumoperitoneum and peritonitis. ( info)

4/534. Combined yolk sac tumor and adenocarcinoma in a gastric stump: molecular evidence of clonality.

    BACKGROUND: Extragonadal yolk sac tumors of the gastrointestinal tract are extremely rare neoplasms. Their greater rarity compared with other extragonadal yolk sac tumors suggests that different pathogenetic mechanisms could be involved according to the site of origin. This report describes a case of a combined yolk sac tumor and adenocarcinoma that arose in a gastric stump in a man age 61 years 43 years after he underwent distal gastric resection and gastrojejunostomy (Billroth II operation) for a benign duodenal ulcer. The coexistence of an adenocarcinomatous component with the yolk sac component suggests that the two histologic patterns may represent distinct phenotypes arising from a common mucosal epithelial cell. methods: Immunohistochemical and molecular techniques were used to define the mutation pattern of p53 in both components of the tumor. RESULTS: Single-strand conformation polymorphism and sequencing analyses demonstrated the same pattern of p53 mutation in the adenocarcinomatous and yolk sac tumor components. CONCLUSIONS: This finding suggests that the two tumors could have been derived from the same cellular clone and supports the hypothesis that the two components represented a heterogeneous differentiation of the same tumor.

5/534. helicobacter heilmannii associated erosive gastritis.

    The spiral bacteria, helicobacter heilmannii (H. heilmannii), distinct from helicobacter pylori (H. pylori), was found in the gastric mucosa of a 71-year-old man without clinical symptoms. The endoscopic examination revealed erosive gastritis. Rapid urease test from the antral specimen was positive, but both culture and immunohistological staining for H. pylori were negative. touch smear cytology showed tightly spiral bacteria, which were consistent with H. heilmannii. At the second endoscopy after medication regimen for eradication of H. pylori, inflammation was decreased and the rapid urease test was negative. The second cytology showed no evidence of H. heilmannii. Anti-H. pylori therapy may be a useful medication for H. heilmannii. ( info)

6/534. Metastasis of an esophageal carcinoma to a giant gastric ulcer.

    In patients with esophageal carcinoma it is considered that stomach metastasis is induced mainly via the lymphatic route rather than via the bloodstream route that is common in other types of distant organ metastasis. A 56 year-old patient is reported who underwent synchronous subtotal esophagectomy and total gastrectomy for a middle third esophageal carcinoma and a giant peptic ulcer within the gastric fundus. The final histopathologic examination revealed a squamous cell carcinoma of the esophagus with concomitant squamous tumor implantation within the gastric ulcer. The increased cell proliferation in the ulcer margin can serve as a "biological background or base" for implantation. ( info)

7/534. Pyloric channel stricture secondary to high-dose ibuprofen therapy in a patient with cystic fibrosis.

    OBJECTIVE: To describe a case of pyloric channel stricture secondary to high-dose ibuprofen therapy in a pediatric patient with cystic fibrosis. CASE SUMMARY: A 12-year-old white girl started taking high-dose ibuprofen to treat the pulmonary manifestations of cystic fibrosis. The peak plasma concentration at dose initiation was within the accepted therapeutic range. Approximately one month later, the patient developed emesis and intolerance of solid foods, which persisted for several months and resulted in a weight loss of seven kilograms. The patient was referred to a pediatric gastroenterologist, who performed an upper endoscopy and subsequently diagnosed a pyloric channel stricture. The patient's pyloric channel was successfully dilated with two balloons. It is felt that the pyloric stricture developed from healing antral/pyloric channel ulcers. ibuprofen was discontinued and omeprazole therapy was begun. Over the course of the following year, the patient was asymptomatic. Follow-up upper gastrointestinal barium swallows were normal. DISCUSSION: When used for analgesia and fever in the pediatric population, ibuprofen has been shown to be a relatively safe drug. While it is known that ibuprofen may cause gastrointestinal adverse effects, the pediatric population is at lower risk; however, large doses of ibuprofen increase the risk of gastrointestinal adverse effects. The use of large doses of ibuprofen in the treatment of cystic fibrosis is a relatively new therapy. Limited data thus far in cystic fibrosis patients do not suggest increased risk of gastrointestinal complications. CONCLUSIONS: Limited data to date indicate that ibuprofen, when used in large doses to treat the pulmonary manifestations of cystic fibrosis, is relatively safe. However, because of the potential risks to the gastrointestinal tract of high-dose ibuprofen therapy, clinicians should be aware of its possible complications. ( info)

8/534. intestinal obstruction and gastrointestinal bleeding due to systemic amyloidosis in a woman with occult plasma cell dyscrasia.

    A 60-year-old woman presented to our hospital with repeated vomiting. Upper gastrointestinal endoscopy revealed a 1 cm diameter ulcer with clean base on the roof of the gastric antrum. Histological examination of gastric biopsies revealed abundant amorphous eosinophilic deposits in the submucosa. congo red stain for amyloid was positive. A barium follow-through study revealed a mass in the jejunum causing incomplete obstruction. urine for bence jones protein was negative. serum protein electrophoresis did not reveal any abnormal band and serum immunoelectrophoresis did not detect any monoclonal immunoglobulin. bone marrow examination, however, revealed an increased proportion of plasma cells. Subsequent immunohistochemical staining demonstrated monoclonal lambda light chains in the marrow plasma cells, thereby confirming a plasma cell dyscrasia. amyloidosis involving the gastrointestinal tract can produce a wide variety of non-specific symptoms and signs. A high index of suspicion is necessary to arrive at an early diagnosis. Management consists of supportive therapy for the gastrointestinal tract as well as treatment of the underlying condition.

9/534. Amelioration of acromegaly after pituitary infarction due to gastrointestinal hemorrhage from gastric ulcer.

    We report a rare case of acromegaly in which pituitary infarction possibly developed in a GH-producing pituitary adenoma following gastrointestinal bleeding from peptic ulcer. In this case, pituitary infarction resulted in spontaneous remission of acromegaly associated with diabetes mellitus. In addition, detailed histological investigation revealed that clinically silent pituitary apoplexy was mainly an acute ischemic event which occurred recently in a GH-producing adenoma. This event led to massive coagulation necrosis of the tumor and endocrinological improvement. ( info)

10/534. Sonographic "gastric corona sign": diagnosis of gastric pneumatosis caused by a penetrating gastric ulcer.

    We present a case of gastric pneumatosis associated with splenoportal venous gas caused by a giant penetrating gastric ulcer. On sonography, the gastric pneumatosis appeared as a circular hyperechoic band with distal reverberations due to gas collection in the gastric wall; we termed this appearance the "gastric corona sign. "awareness of this sonographic sign may aid in the early diagnosis of gastric pneumatosis. ( info)
