The primary gastrointestinal lymphomas in Shiraz, Iran, and Richmond, Virginia, USA were compared. Upper duodenojejunal lymphoma is always associated with atrophy of the surrounding nonlymphomatous mucosa, plasma cell infiltration and formation of lymph follicles. This is frequently linked to repeated gastroenteritis leading to mucosal atrophy, mutation of plasma cell precursors and secretion of alpha-heavy-chain. Gastrointestinal lymphoma in the USA and other industrialized countries is found in the stomach, where it is accompanied by superficial perifoveolar plasma cell gastritis of the surrounding mucosa, or in the performed lymphoid tissue of the ileocolon, surrounded usually by normal mucosa. A hypothesis for the pathogenesis of the different types of primary gastrointestinal lymphoma, considering the geographic distribution, and mucosal and immunologic antecedents, is presented.

11.7% of all cases with inability to work, 11.3% of all days with inability to work, and 13.6% of all dismissals from hospital of working people concern diseases of the digestive system. Gastroenterological diseases occupy an anterior place in inability to work. The inability to work is essentially determined by 7 diagnoses--gastritis and duodenitis, cholelithiasis, gastroenteritis and colitis, cholecystitis and cholangitis, ulcus ventriculi and duodeni, acute appendicitis. They comprise 78% of the days of inability to work. The endoscopic diagnostics is further to be developed with the further improvement of the organisation of treatment, particularly the cooperation between outpatient department and hospital and the interdisciplinary work.

It is now well documented that a characteristic mucosal lesion of the proximal small intestine is present in acute nonbacterial gastroenteritis. To determine whether a gastric mucosal lesion also accompanies this illness, stool filtrate containing Norwalk agent was given orally to 15 volunteers after base line biopsies of gastric fundal and/or antral mucosa had been obtained. Gastric fundal and/or antral biopsies were then obtained serially between 24 and 168 hr after administration of the inoculum. Nine volunteers developed symptoms of gastroenteritis. gastric biopsies from those with normal base line fundal and/or antral biopsies remained normal during and after clinical illness. Those volunteers who had mild to moderate gastritis in their base line biopsies showed persistence but no progression of the lesion during illness. In 4 of the volunteers who became ill, intestinal biopsies were available and showed the typical gastroenteritis lesion. These results indicate that acute infectious nonbacterial gastroenteritis induced by Norwalk agent is not associated with histologically detectable gastric mucosal lesion.

Cytomegalovirus (CMV)-induced interstitial pneumonitis is a well-known lethal complication in bone marrow recipients. CMV is also known to cause gastroenteritis. We report the first case of a bone marrow recipient who developed CMV-induced gastritis which is verified both histologically and virologically. The gastritis preceded the interstitial pneumonitis which was detected in an early stage and was successfully treated. We propose that bone marrow recipients who show signs and symptoms of gastritis undergo an endoscopic examination, and that biopsied specimens should be scrutinized for CMV by both histological examination and culture investigation.

Antibiotics have an important place in the management of gastrointestinal disease. Recent studies have demonstrated efficacy in acute bacterial gastroenteritis caused by salmonellae and campylobacteriaceae, shigellae and enterotoxigenic strains of E coli (ETEC). Tetracycline remains effective in cholera. Antibiotic resistance is widespread amongst the enteric pathogens and can quickly spread during epidemics of infective diarrhoeas. It is important that antibiotics are reserved for the treatment of serious infections lest their effectiveness in these conditions be lost. Campylobacter pylori appears to be an important cause of chronic active gastritis and is amenable to treatment with antibiotics and bismuth salts. The role of C. pylori in the pathogenesis of peptic ulcer disease is not yet established but there is mounting evidence that antibiotic treatment will have a place in the treatment of this common condition. The effect of antibiotics on the normal intestinal microflora can have serious consequences. It is a major cause of resistance in urinary tract pathogens, can result in outbreaks of hospital infection with resistant organisms and frequently results in C. difficile associated diarrhoea.

Rabbits were treated with a single oral dose (1, 2, 4, 6, 8, 10 or 15 mg/kg body mass) of T-2 fusariotoxin. Doses of 4 mg or higher killed the animals in 24 to 48 h. As opposed to the controls, in the treated rabbits gross pathological and histopathological examinations revealed acute catarrhal gastroenteritis, necrosis of lymphoid cells of the gastrointestinal mucosa, centrolobular dystrophy of the liver, necrosis of cells of the mononuclear phagocyte system (MPS) in the liver, tubulonephrosis, focal dystrophy of the adrenal cortex, lymphocyte depletion involving both T- and B-cell-dependent zones of the lymphoid organs (spleen, lymph, ampulla ilei), and depletion and necrosis of the myelopoietic cell colonies of the bone marrow. Similar but milder changes were observed in surviving rabbits exsanguinated 48 h after treatment. In addition to the direct damage done to the digestive tract mucosa and liver, the toxin severely damaged the cells participating in humoral and cell-mediated immunity and in the local defence of the intestinal mucosa, and markedly impaired phagocytosis and granulocytopoiesis. In another experiment rabbits were given oral doses of 2 mg/kg body mass T-2 toxin daily for several days. One rabbit was killed by bleeding every day. In rabbits killed beyond day 7 there was subacute catarrhal gastritis, emaciation, and hypertrophy of the adrenal cortex.

Bacteria of what are now regarded as the genus Campylobacter were first isolated in 1909, but initially were considered as pathogens of animals only. Although the first human infections were reported in 1947, the importance of campylobacters as causes of intestinal illnesses was not widely recognized until the 1970s. C. jejuni and closely related species are now known as leading causes of bacterial gastroenteritis. C. fetus causes systemic diseases, primarily in compromised hosts. Most recently, C. pylori has been associated with antral gastritis and peptic ulcer disease. The pathogenic mechanisms for these three related organisms, while still being elucidated, are now known to be substantially different.

Salmonella typhimurium infection was diagnosed in 186 patients aged 18-56. The clinical picture was that of gastroenteritis (73.1%), enteritis (14.0%), gastritis (6.45%), gastroenterocolitis (6.45%). Salmonellosis of moderate severity presented in 88.7% of patients, a severe course occurred in 11.3%. Concomitant disorders arose in 22.6% of cases. Immunological investigation disclosed T-lymphopenia, reduced number of multireceptor RFC, both T-helpers and T-suppressors. The levels of 0-lymphocytes and CIC were on the increase. Salmonellosis of long duration was characterized by hyperactivity of autoimmune reactions.

The efficacy of the oxfendazole pulse release bolus system for the control of parasitic gastroenteritis and parasitic bronchitis in first-season grazing calves was evaluated in Belgium. Twenty-two calves were allocated to two groups. The calves in one group received a bolus at the time of turn out, while the other group remained untreated. The efficacy of the bolus was assessed by comparison of faecal worm egg counts, plasma pepsinogen concentrations, the antibody response to Ostertagia, Cooperia and Dictyocaulus species total plasma protein and albumin concentrations, and weight gains throughout the grazing season and the housing period. The oxfendazole pulse release bolus provided good control of parasitic gastroenteritis dominated by ostertagia. The effects of parasitic gastritis were greatly reduced as shown by the significantly lower values of serum pepsinogen and ostertagia antibody titres. The use of the bolus further reduced the adverse effects of parasitism as indicated by better liveweight gains and normal total plasma protein and albumin concentrations whereas in the untreated control group hypoproteinaemia and hypoalbuminaemia were observed. Most animals exhibited clinical signs of parasitic bronchitis at the end of the grazing season, and the bolus may not adequately control parasitic bronchitis in all cases at all times.

Two calves given a mean of 16.1 g and 16.4 g ripe Castanospermum australe seeds/kg body weight daily for 13 and 16 days respectively developed haemorrhagic gastroenteritis. The first calf died. The second calf had mild myocardial degeneration and necrosis and mild nephrosis at necropsy. Two calves given a mean of 16.8 g unripe C. australe seeds/kg body weight daily for 18 days remained clinically normal and had mild gastritis at necropsy. The activity of alpha-glucosidase was reduced in the mononuclear cells of peripheral blood and in skeletal muscle. This was attributed to the presence of the indolizidine alkaloid, castanospermine, in the seeds. The toxin causing the gastroenteritis and other lesions is unknown.
