A 2-year-old Miniature Dachshund was admitted to the hospital because of fever, frequent vomiting, and watery diarrhea. An intra-abdominal mass and a gastric ulcer were detected. At laparotomy, the omentum was yellow but not icteric, irregularly thickened, and fragile, and a large mass involving the root of the mesentery and the gastrosplenic ligament was found. The histopathologic diagnosis was steatitis, and the dog was treated with prednisolone and cyclosporine for 2.5 years. After 1.5 years, the abdominal mass was not detectable. The dog died suddenly from perforation of the small intestine caused by a foreign body. Necropsy revealed severe adhesions between portions of the small intestine, and cicatrization of the mesentery. Cause of the mesenteric and omental steatitis was not apparent.

A 66-year-old man with a history of abdominal pain, diarrhoea and weight loss was admitted for evaluation. Gastroscopy disclosed a severe gastric ulceration covering the lesser curvature. There was none of the usual risk factors for peptic ulcer disease and no malignancy was found. After 2 weeks' treatment with a proton pump inhibitor no healing was observed. The patient had a known atherosclerotic vascular disease, and angiography disclosed severe mesenteric ischaemia. After a revascularization procedure with stenting of the superior mesenteric artery was performed, the patient's symptoms disappeared. Healing of the gastric ulceration was observed at a further gastroscopy 2 weeks later. Chronic ischaemia is a rare cause of gastric ulcer, but should be suspected when no other cause is found and when the usual treatment with proton pump inhibitors does not result in healing.

Byrsonima basiloba A. Juss. species is a native arboreal type from the Brazilian "cerrado" (tropical American savanna), and the local population uses it to treat diseases, such as diarrhea and gastric ulcer. It belongs to the Malpighiaceae family, and it is commonly known as "murici." Considering the popular use of B. basiloba derivatives and the lack of pharmacological potential studies regarding this vegetal species, the mutagenic and antimutagenic effect of methanol (MeOH) and chloroform extracts were evaluated by the Ames test, using strains TA97a, TA98, TA100, and TA102 of Salmonella typhimurium. No mutagenic activity was observed in any of the extracts. To evaluate the antimutagenic potential, direct and indirect mutagenic agents were used: 4 nitro-o-phenylenediamine, sodium azide, mitomycin C, aflatoxin B(1), benzo[a]pyrene, and hydrogen peroxide. Both the extracts evaluated showed antimutagenic activity, but the highest value of inhibition level (89%) was obtained with the MeOH extract and strain TA100 in the presence of aflatoxin B(1). Phytochemical analysis of the extracts revealed the presence of n-alkanes, lupeol, ursolic and oleanolic acid, (+)-catechin, quercetin-3-O-alpha-L-arabinopyranoside, gallic acid, methyl gallate, amentoflavone, quercetin, quercetin-3-O-(2"-O-galloyl)-beta-D-galactopyranoside, and quercetin-3-O-(2"-O-galloyl)-alpha-L-arabinopyranoside.

Gastrocolic fistula formation is an extremely rare complication of gastric ulcer disease. We report a case of a 55-year-old man who presented with a two-month history of abdominal discomfort, postprandial diarrhea, nausea and faecal vomiting. Upper gastrointestinal endoscopy showed an ulcer in the greater curvature of the stomach. Barium enema examination revealed an obvious gastrocolic fistula between the greater curvature of the stomach and the transverse colon. The involved segment of the colon was excised and truncal vagotomy and antrectomy was performed. The patient was discharged on the 7th postoperative day. It is concluded that cases with postprandial diarrhea and nutritional disturbances after gastric surgery should remind us of the probability of gastrocolic fistula formation.

We report a 49-year-old Chinese male with locally advanced gastric adenocarcinoma achieving pathological complete response after neoadjuvant chemotherapy with trastuzumab-containing regimen. He underwent esophagogastroduodenoscopy in September 2009, which revealed a 2-cm gastric ulcer on the lesser curvature proximal to angularis. Biopsy of gastric ulcer showed moderately differentiated adenocarcinoma with overexpression of human epidermal growth factor receptor 2 (HER2) by immunohistochemistry and fluorescence in situ hybridization. Further workups with endoscopic ultrasound, computed tomography and positron emission tomography staged his cancer as T3N1M0. He received 3 cycles of neoadjuvant chemotherapy consisting of trastuzumab, oxaliplatin, docetaxel and capecitabine without severe toxicities except grade 2 diarrhea near the completion of cycle 3 requiring discontinuation of capecitabine. Afterwards, he received total gastrectomy with extended D2 lymph node dissections showing pathological complete response. He went on to receive 3 more cycles of chemotherapy postoperatively. The role of trastuzumab as a part of perioperative therapy in gastric cancer overexpressing HER2 is worth further investigation.

Prostaglandins play important roles in the gastric mucosal protection and gastric ulcer healing. Non-steroidal anti-inflammatory drugs (NSAIDs) including aspirin are widely used for the aged patients. Administration of the prostaglandin derivatives has been proven to be effective for both prevention and treatment of gastric ulcers associated with NSAIDs, and prostaglandin derivatives are recommended for NSAIDs-induced gastric ulcers by the Japanese guidelines. The important side effects include abdominal pain, flatulence, and diarrhea. Recent advances in diagnostic methods including video capsule endoscopy and balloon endoscopy have enabled us to examine the entire small intestine, and we recognize that prevalence of small intestinal damage in patients taking NSAIDs is high. Prostaglandin derivatives are also useful for these small intestinal damages.

Apical application of lysophosphatidic acid (LPA), a growth-factor-like phospholipid, was shown to prevent or restore gastrointestinal (GI) disorders, such as diarrhea and stomach ulcer, in experimental animals. Because LPA is formed from phosphatidic acid (PA) by the activity of digestive phospholipase A(2), PA is a potential component for dietary treatment of such GI disorders. Here, we quantified PA contained in 38 foodstuffs and 3 herbs by a thin-layer-chromatography-imaging technique. Vegetables belonging to Brassicaceae, such as cabbage leaves (700 nmol/g of wet weight) and Japanese radish leaves (570 nmol/g), contained higher amounts of PA than other foodstuffs. Amounts of PA in fruits, cereals, and starchy root vegetables were below 300 nmol/g. Animal foodstuffs contained low amounts of PA (<60 nmol/g). Interestingly, leaves of Mallotus japonicas, a Japanese edible herb used for treatment of stomach ulcer, had the highest PA (1410 nmol/g) among those examined. The data shown here will be useful for the development of dietary treatment for a damaged GI tract.

Guggulsterone (GS) is a phytosterol derived from the gum resin of guggul plants that have been used traditionally to treat various disorders such as burns, wounds, gastric ulcer, cough, gum diseases, urinary complaints, diarrhea, stomach cramps, fascioliasis, and intestinal worms. It has anti-inflammatory and antioxidative properties and has recently attracted substantial attention due to its cancer chemopreventive and therapeutic potential exemplified by its antiproliferative, antimetastatic, and proapoptotic properties in many cancer cell lines and animal models. This review highlights some of the cancer chemopreventive/therapeutic targets of GS and the underlying molecular mechanisms.

This commentary summarizes the laboratory investigations and clinical trials published recently involving per-oral application of IgY supplemented food for specific orogastrointestinal disease prevention and control purposes. The prolonged use and misuse of conventional antibacterial drugs has spawned antibiotic resistant microbes prompting scientists to search for other germ-killing options. In particular, the use of IgY as a novel mode of immunotherapy using oral chicken immunoglobulin (IgY) to confer passive immunity has gained much interest as an inexpensive non-antibiotic alternative for the prophylaxis and treatment of a wide variety of infectious diseases. The stability of IgY in the orogastrointestinal tract and its safety profile has been well-documented. IgY has been used in the treatment or prevention of dental caries, periodontitis and gingivitis, gastritis and gastric ulcer, oral thrush and infant rotavirus diarrhea. The recent clinical trials on IgY with encouraging results has catapulted into the market novel nutraceutical or health supplements for therapeutic or prophylactic intervention based on the consumption of mono-specific or mixed IgY formulations. With recent trends in consumer preference for natural materials to alleviate health concerns, the increasing healthcare costs and the recent advances in drug delivery systems, IgY is likely to shift from its mainly functional food status toward pharmaceuticalization in the foreseeable future.

Microscopic colitis (MC) is a disease with intestinal mucosal inflammation causing diarrhea, affecting predominantly middle-aged women. The etiology is unknown, but increased prevalence of autoimmune diseases in these patients has been described, although not compared with controls or adjusted for confounding factors. The aim of this study was to examine the prevalence of common diseases in patients with MC and controls from the general population. Hypertension, rheumatoid arthritis, asthma or bronchitis, ischemia, and diabetes mellitus were more prevalent in patients than in controls. The prevalence of gastric ulcer and cancer did not differ between the groups. Besides corticosteroids, many patients were also being treated with proton pump inhibitors, antidepressant drugs, angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists, statins, thyroid hormones, and beta-blockers. More patients than controls were former or current smokers (72.5% versus 57.7%). Thus, MC patients have an increased prevalence of several diseases, not only of autoimmune origin.
