The relationship between the secretion of pepsin 1 (the most electronegative of the pepsins), and the smoking habits of 219 patients has been investigated. Significantly more cigarette smokers with peptic ulceration (72.5%) secreted pepsin 1 in greater than trace amounts after pentagastrin or histamine than did non-smokers with ulceration (51.2%). Differences of a similar order were found for men with duodenal ulcer, women with duodenal ulcer, and all patients with gastric ulcer, but the difference was statistically significant only for men with duodenal ulcer. Significantly more patients with peptic ulcer smoking six to 15 cigarettes/day secreted moderate or high concentrations of pepsin 1 than did heavier smokers or non-smokers. There was no significant association between cigarette smoking and pepsin 1 secretion among 74 patients without ulceration. Maximal acid output was not significantly related to smoking in any group studied. The findings add to the increasing body of evidence linking pepsins and pepsin 1 with the pathogenesis of peptic ulceration.

Pepsin 1, the ulcer-associated pepsin, occurred significantly more frequently in the gastric juice of those patients with duodenal ulcer who did not secrete A, B, or H antigens into gastric juice than in those secreting these antigens. This observation may explain the increased proportion of such non-secretors among patients with duodenal ulceration. In patients with gastric ulcer and non-ulcer dyspepsia, and in a miscellaneous group of patients, there was no association of pepsin 1 secretion with secretor status, suggesting that the association noted in duodenal ulceration is an indirect rather than a direct one. No increase of pepsin 1 occurred in group O patients with peptic ulcer, so that the increased proportion of such patients in peptic ulcer does not arise from differences in pepsin 1 secretion.

The incidence of gastric carcinoma was studied in a series of 210 patients presenting with apparently benign gastric ulcer. In eight cases (3.9 per cent), carcinoma was diagnosed within 18 months and was almost certainly present from the outset; in 2.4 per cent the diagnosis was delayed for over three months, and the five-year death-rate due to gastric carcinoma was 3.2 per cent. In a mean follow-up period of 5.7 years after the first diagnosis of an ulcer (8.2 years after first symptoms), three fresh cases of gastric carcinoma were found, and in two of these the cancer was at a different site from the ulcer. The five-year incidence of fresh gastric carcinoma was 0.6 per cent. Unsuspected superficial spreading carcinoma was detected by histology in 5.4 per cent of gastrectomy specimens. The significance of these findings is discussed in relation to the management of gastric ulcer and the early diagnosis of cancer.

In a series of 500 patients admitted to hospital for upper digestive hemorrhage, the authors studied the influence of taking drugs on the clinical characteristics and course of the original disease. Taking aspirin is exceptional before rupture of esophageal varices. One may isolate a homogenous group of elderly women consuming aspirin and another anti-inflammatory drug, and bleeding from a gastric ulcer. One may also isolate another group of men, bleeding from acute gastro-duodenal lesions after taking aspirin alone. If one considers apart portal hypertension, owing to its extreme gravity, one may note that the prognosis depends on the age. One patient out of five, dies of hemorrhage after the age of 60 years. Taking an anti-inflammatory drug at this age is thus not harmless.

A patients with a cytomegalovirus (CMV) post-transfusion syndrome developed upper gastrointestinal tract bleeding; subsequently, a gastric ulcer was found. CMV was searched for in the gastroscopic biopsy material because the gastric ulcer had occurred in a setting of CMV mononucleosis. CMV cells were found in gastroscopic biopsy sections and CMV was also cultured from biopsy material. This study illustrates the feasibility of antemortem diagnosis of CMV-associated disease of the upper gastrointestinal tract.

10 YEARS AFTER B-I-partial gastrectomy for a proven benign gastric ulcer a multicentric early gastric carcinoma type II b, c was detected by endoscopy and histology. This early carcinoma differed from published cases in respect of its macroscopic classification, localization and expansion. The carcinoma situated next to the anastomosis invaded the duodenal mucosa. It also invaded a polypoid fold caused by the previous surgery, thus imitating an early gastric carcinoma type I.

The authors report the case of a 57 year old man who had taken for several years large quantities of alkaline drugs to relieve pain due to a gastric ulcer. This man presented acute digestive symptoms, and a confusional syndrome explained by various metabolic disturbance and especially hypercalcemia at 145 mg. Stopping the alkalis permitted within a few days the disappearance of the clinical symptoms and the correction of the laboratory disturbances. In the light of this case, the authors study the main clinical cases which have been described either in their acute form or in their chronic form (Burnett's syndrome). They discuss above all the physiopathology of these manifestations and it seems to them that the hypercalcemia is more important than the alkalosis. It remains to be explained why only a small number of subjects are exposed to these metabolic complications. There seems to be an individual hypersensitivity for under normal conditions, excess calcium is not sufficient to induce hypercalcemia.

During a combined acupuncture-neural therapy-treatment on account of a gastric ulcer several lesions with vast haemorrhages in the abdominal cavity and in the retroperitoneal space on the right (lesions of the kidney) were produced. At the operation a duodenal ulcer without perforation was found. The competence of the neural therapy in its relation to the complications is discussed, the indication to the application of these forms of therapy in such cases is refused.

A case of fibrosarcoma of the breast metastatic to the stomach and small bowel is reported. Upper gastrointestinal bleeding secondary to a "bull's eye" or "target" gastric ulcer was successfully treated by surgical resection.

The giant stomach ulcer can be defined as a crater measuring more than 30 mm in diameter. This variety of stomach ulcer represents 10-15% of the whole range of gastric ulcers, but they are not quite different from the nosologic point of view. It appears effectively that no etiopathogenic clinical or evolving particular factors can distinguish this kind of ulcer from the niches of normal size. To be taken into consideration is the risk of transforming into cancer which is multiplied by 3 or 5 times when compared with normal stomach ulcers, whence the importance of the endoscopy with many biopsies. In spite of the endoscopy the percentage of error is 5%, this is the reason for which, when in doubt, the more or less extensive gastric resection of the total gastrectomy is required with even more necessity then in normal cases of ulcers.
