Follow-up study on patients with non-alcoholic and non-diabetic fatty liver.

From a group of 424 patients with histologically verified fatty liver 92 patients without diabetes mellitus and alcohol abuse were subjected to follow-up examination for 3 1/2 years. 56 patients underwent second liver biopsy at this time; 20 of these patients had shown marked fatty liver at the initial liver biopsy examination. These 20 patients with marked fatty liver and 25 further patients with moderarte fatty liver could be followed up 5 and 7 1/2 years later; the clinical examination, the various liver function tests, liver scan and blind liver biopsy did not show any evidence of progression of fatty liver towards chronic inflammatory liver disorders or precirrhotic states. This clinical study therefore suggests the harmlessness of non-alcoholic fatty liver.

[Cimetidin treatment of duodenal ulcer resistant to antacid therapy (author's transl)].

A selected group of 21 patients having received antacids (neutralizing capacity less than 50 meq HCl/d) as treatment for duodenal ulcers showed no improvement of the disease as demonstrated by endoscopic control after 8-16 weeks. Subsequent treatment of this group with 1 g Cimetidin/d for periods of 4-8 weeks was successful as far as healing of the ulcers is concerned in 85% of the cases, however symptoms of duodenitis persisted. In a control group of 39 patients which did not improve after 8 weeks of treatment with antacids the same therapy was continued for another 8 weeks; during this second period ulcers disappeared in 12 patients = 30% of the group. Improvement of symptoms resulted on the average after 6 days of therapy with cimetidine. One third of the patients treated with cimetidine relapsed with ulcers after approximately 4 months as demonstrated by endoscopy. Patients with duodenal ulcers resistant to therapy with antacids do represent a selected group suited to test the potency of new therapeutic methods as for instance treatment with cimetidine.

Morphological findings of different areas of gastric mucosa in patients with achlorhydria, extreme hypochlorhydria, normochlorhydria and their relationship to serum gastrin levels: evidence for two different types of gastritis.

The morphological changes of gastric mucosa taken from different areas has been studied in patients of approximately the same age with achlorhydria, extreme hypochlorhydria and normochlorhydria. The serum gastrin level and parietal cell antibodies were determined in the achlorhydric parietal cell antibodies were determined in the achlorhydric patients. In the latter the diffuse gastritis was localized in the corpus-fundic area, while the changes in the antral region were few and occurred mostly in the superficial zone. In normochlorhydric patients however, the diffuse gastritis was localized in the antral region, with only few changes at the corpus-fundic area. In patients with extreme hypochlorhydira either the fundic or the antral region was involved. Besides the diffuse gastritis intestinal metaplasia, pseudopyloric metaplasia, and atrophy of mucosa were also observed, although much less commonly. The increase of gastrin level could not be related to a definite morphological pattern in the gastric mucosa. It can be assumed that each of the two types of gastritis has a different natural history; the antral site of gastrititis cannot be transformed into the fundic site, nor can the fundic site be transformed into the antral site.

[Intestinal pseudo-obstruction].

The report is the first on intestinal pseudoobstruction in german literature. The most impressive clinical signs and symptoms in our case were uncharacteristic abdominal discomfort, flatulence, and relapsing diarrhoe over a period of two decades. Finally we observed periods of inappetence, occasional vomiting a few hours after food intake and kachexia developing in 8 months. A localized dilatation of the duodenum and upper jejunum associated with complete atonia was found by laparatomy. The dilated segment of the intestine was largely resected. An impressive decrease in the thickness of the muscularis propria with splitting of muscle fibres and intact neural plexus was found by histology. After treatment with antibiotics it came to a satisfying restitution of the patient. The hitherto very rare clinical syndrome of localized dilatation of intestine with severe disturbance of motility and the published cases of the world literature are discussed.

Daily fluctuation of lithogenicity in bile in the postoperative period in cholecystectomized patients.

The lithogenicity of bile samples taken over 14 hrs from 7 a.m. to 9 p.m. on two consecutive days at 4-5 hrs intervals has been measured in 7 freshly colecystectomized patients on the 7th to 9th postoperative days. The values have also been estimated additionally in 4 patients 1 and 2 hrs after meal intake. It was found that the lithogenicindex is higher at 16 and 21 hrs than at 7 and 11 hrs. The lithogenicity began to increase 2 hrs after lunch. The observed difference between our results and those of other authors could be due either to the changed enterohepatic circulation before the begin of our study or to the different types of populations studied.

[Is there a risk of transmitting hepatitis by gastroduodenoscopy?].

Among 211 patients undergoing gastroduodenoscopy five had been carriers of Australia antigen. The same instrument had been used on all, and follow-up examination was carried out two and four months after the gastroscopy. Twelve patients died during the follow-up period of their original disease. Two additional patients became Australia-antigen positive. One of these had liver cirrhosis. In the other, surgery with multiple infusions of albumin had been carried out after gastroscopy and could have been the cause of the Australia-antigen transmission. No proven case of hepatitis transmission occurred in this group of patients.
