When a group of 3-month-old pigs was moved to another location, several died from internal bleeding. Two pigs that were necropsied had large esophagogastric ulcers, hepatic fibrosis with "milk spots" and swollen edematous lungs. The ulcers involved the full thickness of the gastric mucosa with pronounced eosinophilic infiltration and perivascular cuffing of the submucosal vessels. There was an acute interstitial and granulomatous pneumonia with an inflammatory exudate composed mainly of eosinophils. Ascarid larvae were recovered from the lungs. Gastric ulceration could have resulted from a second exposure to Ascaris suum infestation because pigs not removed from their original location did not develop ulcers.

The authors analyse the results of esophago-gastro-duodenal fibroscopy in 930 symptomatic patients. Ninety one per cent of them had lesions. Inflammatory pathology was predominant: esophagitis, gastritis and duodenitis were seen in 21.5%, 47% and 29.08% respectively of the patients investigated. Gastritis accompanied 75.13% of cases of esophagitis and 76.4% of duodenitis, and was associated with the demonstration of the presence of Helicobater pylori in gastric biopsies in 56.41% of patients with that lesion. The relatively high incidence of carcinoma of the esophagus (2.7%) is a particular feature of this study, while that of carcinoma of the stomach (1%) was in accordance with classical data. Duodenal ulcer was found in 18% of patients as compared with 5.16% for gastric ulcer. From a pathophysiological standpoint, mention is made of traditional diet (hot, highly spiced), self-medication and intestinal parasite infestation in causing inflammatory lesions. Finally, emphasis is placed upon the role of Helicobacter infection in the development of chronic gastritis. The high rate of infection with this organism and its involvement in the mechanisms of duodenal ulcerogenesis could explain the high incidence of duodenal ulcers in our group and in studies emanating from developing countries.

Results of semiquantitative culture of the gastric mucosa for Campylobacter pylori (C. pylori) are reported. The samples were obtained by biopsy at the pyloric antrum along the lesser curvature from 197 patients with various gastric or duodenal disorders. 1) C. pylori was found in most cases with duodenal ulcer (100%), gastric ulcer (87.7%) and acute gastric mucosal lesion (AGML) (87.5%). Relatively heavy infestation was usual in these diseases, while relatively small amounts of the organism were found in various frequencies in other gastroduodenal disorders. 2) Samples from gastric ulcer cases under H2-blocker treatment had reduced amount of C. pylori as compared with those from untreated cases (p less than 0.01). C. pylori decreased in quantity in each case of AGML after successful treatment with a H2-blocker but not in a case without favorable response. 3) C. pylori distributed evenly among the gastric mucosa sampled at the margin of the ulcer and that at a relatively healthy portion in the pyloric antrum of the same stomach. 4) There was a modest, positive correlation between the amount of C. pylori and that of inflammatory cells, especially of neutrophilic granulocyte, in the gastric mucosa (r = 0.679), while there was a weak, negative correlation between the former and the extent of intestinal metaplasia of the epithelial cells (r = -0.479). 5) Quantitative rather than qualitative observation of C. pylori seems mandatory for considering the relevance of the bacterium to gastric and duodenal disorders. Although C. pylori can be found in the mucosa of the stomach with any type of disorder, its quantity tends to parallel with the activity of duodenal as well as gastric ulcer.

Three cases of granulomatous inflammation in gastric biopsies showing Campylobacter pylori infestation are described. This type of reaction to Campylobacter pylori has not previously been described, and occurred in 1.1% of gastric biopsies containing Campylobacter-like organisms (CLO), in this series of all gastric biopsies submitted for histological examination during one year. Two other cases each showed a mucosal granuloma: one was a patient with Crohn's disease and the other had foreign body giant cells in a biopsy of the edge of a healing gastric ulcer. Each of our three CLO-positive cases with granulomas showed scanty CLO's only. Thus, although granulomatous inflammation associated with CLO's is uncommon as a proportion of all CLO-positive gastric biopsies, these currently represent the commonest condition associated with granulomas in gastric biopsies, in our experience.

121 cases of candidiasis were histologically demonstrated in the course of histological studies of gastric mucosal biopsies in 20 401 patients. Infestation of necrotic tissue with Candida albicans was found exclusively in patients with gastric ulcer, ulcerating carcinoma or lymphoma. Candidiasis was twice as common in carcinoma as in non-carcinomatous gastric ulcer. In the majority of those patients with ulcer who also had Candida albicans mycosis there was was at the same time atrophic or dysplastic gastric mucosa at the edge of the ulcer. Demonstration of candidiasis in biopsy material from gastric ulcer should thus be interpreted as suspicious of carcinoma, until and unless further studies confirm or exclude it.

Anisakiasis is caused by a fish parasite of the Nematode family. This kind of rare helminthozoonosis can mainly be found in countries where consumption of raw fish is traditionally high like Japan, the Netherlands, Pacific Islands, South Europe, Scandinavia, USA, and Canada. Man is the wrong hoste. Clinical manifestation depends on the localisation of penetration in the GI tract. In Japan, predominantly the stomach is affected in 97 % of cases, probably due to hypo- and achlorhydria; whereas mainly intestinal anisakiasis occurs in Europa. We report on a 67-year-old male patient with a gastric infestation of anisakiasis. The patient was on proton pump inhibitor which migh have caused the localisation of the infestation. The anisakis was an accidental endoscopic finding in a patient for control of an H. p.-positive gastric ulcer. Otherwise the patient was free of pain. The helminth (larva III) was endoscopically extracted. Thereafter, the patient remained in good health. Anisakis serology as well as repeated differential blood counts were without finding. The uneventful medical history and the normal blood findings indicate that our patient had a very early stage of infestation of anisakiasis. The patient reported no stay outside of Austria within the last years. However, he consumed on a regular basis "rolled pickled herring" produced by a well-known Viennese company for canned fish. This is the first documented case of this rare helminthozoonosis acquired in Austria.
