Gastroendoscopy was performed on 111 horses (1 to 22 years old) that had signs of abdominal discomfort of variable duration and severity. At least 1 episode of colic had been observed within 48 hours of examination in 31 horses. Recurrent episodes of colic were observed in 28 horses within 2 to 10 days of examination, 31 horses within 11 to 30 days, 12 horses within 31 to 60 days, and in 9 horses at more than 60 days after the initial examination. Gastric ulceration was found in 91 of 111 horses examined. Other abnormalities involving the gastrointestinal tract or other abdominal viscera were not found on examination in 57 of 91 horses with gastric ulcers. The most frequent concurrent abnormalities found in the remaining 34 horses with gastric ulcers were impaction of the large colon (n = 6), colonic tympany (n = 6), peritonitis (n = 6), gastric impaction (n = 4), ileocecal intussusception (n = 3), small-colon impaction (n = 4), and proximal enteritis (n = 2). Thirteen horses with gastric ulceration underwent abdominal surgery, and in 5 horses, lesions were not found at surgery. Gastric ulceration was determined to be the primary cause of colic in 31 horses on the basis of the lack of other abnormalities, clinical response to treatment with histamine type-2 receptor (H2) antagonists, and confirmation of improvement or resolution of gastric ulceration via endoscopy. Gastric ulceration was the suspected cause of colic in 26 other horses on the basis of the lack of other abnormalities, severity of lesions, and clinical response to treatment with H2 antagonists.(ABSTRACT TRUNCATED AT 250 WORDS)

Helicobacter pylori is firmly established as a human pathogen; it fulfils all of Koch's postulates as the infectious agent causing chronic, active (type B) gastritis. Infection is strongly associated with duodenal and gastric ulcer. Recently, gastric mucosal-associated lymphoid tissue lymphoma has been successfully treated by curing H. pylori infection. Because of the evidence that the organism causes chronic gastritis and an increased risk of gastric cancer, it has been classified as a category 1 carcinogen by the World Health Organization. However, the overwhelming majority of people infected have no symptoms. Current eradication therapy is not ideal; there are treatment failures and substantial side effects. As a result, therapy should be reserved for people with clinical symptoms and complications. The infection, if present, should be treated in patients who have endoscopic evidence of mucosal ulcers in the stomach or duodenum. Current evidence does not support treating the infection to prevent gastric carcinogenesis or to alleviate symptoms of abdominal discomfort in the absence of peptic ulcers.

It is known that collections of popular medical prescriptions and instructions appeared in areas without educated physicians, and all previously published manuscripts of this kind are inevitably anonymous. The reported manuscript comprises 23 pages written in sepia ink, appendixed to a prayer book published in 1747, containing popular medical instructions and prescriptions collected and practiced by orthodox priest Mihailo Plamenac in Montenegro at the turn of the 18th century. Mihailo Plamenac took an important part in historical events, as documented by numerous domestic historical data and several letters discovered in The Archives of Vienna. Being the only literate persons at the time, priests were both politicians and military officers, but they also offered medical services to the population. The manuscript comprises advices for various common emergencies (snake bites, urinary retention, contusions, fever, burns, eye injuries, rabies, otitis, traumatic wryneck) and diseases(impetigo, scabies, infertility, gastric ulcer, low back pain) as well as for certain poorly defined conditions (chest pain, abdominal discomfort). Besides medically fully adequate treatment, for example, the remedy against scabies containing sulfur, there are numerous examples of magic and ritual pagan elements, including famous medieval SATOR formula against rabies. Most of the herbs used in prescriptions have been identified: fig, dog rose, hyssop, leek, laurel, absinthe, rosemary, mallow, cypress, elder, endive, mangel, orache, ivy. The manuscript is the first manuscript undoubtedly attributed to a well known historical personality, as indicated in the first page of the manuscript: "This is a medical prayer book by Mihailo Plamenac, left to him by his ancestors."

Gastric ulceration is a prevalent condition of racehorses. A number of models of gastric ulceration have been described, but none mimic the conditions of a horse in training. The objectives of this study were to determine whether gastric ulcers could be induced and maintained in a group of horses in simulated race training. In addition, serum cortisol was measured on a weekly basis to investigate the possibility that stress may be important in the pathogenesis of gastric ulceration. Thirty horses used in the trial were fed Bermuda grass hay and 6 kg of a concentrate diet, and exercised 6 days/week at speed over a distance of 1.6-2.4 km. Serum was collected and gastroendoscopic examinations performed on a weekly basis for the duration of the trial. All horses developed moderate to severe ulceration, and ulcers were maintained for the 56 day period of the trial. Only one horse had signs of abdominal discomfort, which resolved with minimal symptomatic treatment and without the use of anti-ulcer medications. Serum cortisol remained within reference ranges for the duration of the trial. Although there was some variation between the weekly examinations, serum cortisol concentrations were decreased from values obtained at the start of the trial. In this study ulcers developed without the administration of nonsteroidal anti-inflammatory agents or withholding of feed. This model provides a method to study the condition, and to investigate the effects of medications on the healing of ulcers in racehorses.

Invasive techniques for diagnosis of Helicobacter pylori (H. pylori) infection require an endoscopic examination which is expensive and inconvenient and may cause complications. Stool cultures for H. pylori or a direct detection of H. pylori antigen in stools by PCR are expensive, tedious, and have a low sensitivity. We recently used an enzyme immunoassay (EIA) to detect H. pylori antigen in stool specimens. A total of 41 patients were seen at Inha University Hospital, Inchon, Korea between September and October 1998. There were 26 men and 15 women who had an average age of 37.6 years which ranged from 5 to 71 years in the present study. All of these patients came to the hospital complaining of an upper abdominal discomfort and were subjected to endoscopy and biopsies. Fifteen had a gastric ulcer, 13 had a duodenal ulcer, 1 had an early gastric cancer, and there were 12 chronic gastritis patients as shown by endoscopy. The biopsy specimens were examined by histology, CLO test, and cultures and these results were used as gold standards. Stool specimens were tested for the H. pylori antigen by EIA. A dual wavelength cut-off of 0.100 that was recommended by the manufacturer gave a good performance (87.1% sensitivity, 100% specificity, 100% positive predictive value, 71.4% negative predictive value, and a 90.2% efficiency). But the adjusted cut-off value using the receiver operating characteristic curve improved the performance of the test (using the cut-off value of 0.024, the sensitivity, specificity, PPV, NPV, and efficiency were 100%, 90.0%, 96.9%, 100%, and 97.6% respectively). Re-evaluation of the cut-off value may be needed for Korean patients. This technique is non-invasive, rapid, easy-to-use, and shows good performance characteristics for diagnosis of H. pylori infections. Therefore, this technique may be a substitute for gastric endoscopy especially in children and some patients who are unable to tolerate an endoscopic examination and it may be substituted for a serologic test in epidemiological research.

Toll-like receptors (TLRs) play important roles in the signaling of many pathogen-related molecules and endogenous proteins associated with immune activation. -196 to -174del polymorphism affects the TLR2 gene and alters its promoter activity. We investigated the influence of TLR2 -196 to -174del polymorphism on the risk of gastro-duodenal diseases, on the severity of Helicobacter pylori-induced gastritis in a Japanese population. The study was performed on 309 patients with abdominal discomfort and 146 healthy controls. -196 to -174del polymorphism of TLR2 was investigated by allele-specific polymerase chain reaction method in all of the subjects. Gastritis scores of antral gastric mucosa were assessed according to the updated Sydney system in H. pylori-positive subjects (n = 156). Patients with abdominal discomfort was consisted of 80 gastric ulcers (25.9%), 38 duodenal ulcers (12.3%), five gastric + duodenal ulcers (1.6%), 105 patients with gastritis (34.0%) and 81 normal healthy stomachs (26.2%). We did not find any association between TLR2 polymorphism and risk of gastric ulcer, duodenal ulcer, gastric and duodenal ulcer and gastritis compared to healthy controls. However, the TLR2-196 to -174ins allele was associated with severity of intestinal metaplasia in more than 60 years of ages (P = 0.02). The same allele also increased the risks of developing more severe gastric mucosal atrophy and intestinal metaplasia in female subjects (P < 0.05, P = 0.07 respectively). No association was observed between TLR2 polymorphism and severity of neutrophil and mononuclear cell infiltration. Our data suggest that the TLR2-196 to -174ins allele was associated with more severe intestinal metaplasia in patients older than was correlated with severity of gastric mucosal atrophy and intestinal metaplasia in female subjects.

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.

A 11-year-old child diagnosed as chronic tonsillitis and adenoid hypertrophy underwent adeno-tonsillectomy under general anesthesia. After surgery, patient complained with abdominal discomfort, paleness and vomiting, which presented as the old black contents. Complete blood count showed: 45.2 g/L, hemoglobin of red blood cells 2.57 x 10(12)/L, An emergency gastroscopy confirmed gastric ulcer with hemorrage. Hemorrage was controlled and complete blood count results restored to normal after supportive therapy. Gastric ulcer completely recovered two weeks after discharge.
