In July 1981, an outbreak of gastroenteritis occurred at a summer diet camp. Of the 455 campers and staff, 35 per cent developed an illness characterized by abdominal pain, fever, diarrhea, and/or nausea and vomiting. A total of 53 per cent experienced abdominal pain. Seven persons were hospitalized, five of whom had appendectomies. Yersinia enterocolitica serogroup 0:8 was isolated from 37 (54 per cent) of 69 persons examined, including the camp cook and three assistants. An epidemiologic investigation demonstrated that illness was associated with consumption of reconstituted powdered milk and/or chow mein . Y. enterocolitica serogroup 0:8 was subsequently isolated from milk, the milk dispenser, and leftover chow mein . Information obtained during the investigation suggested that the Yersinia had been introduced by a food handler during food-processing procedures.

An outbreak of epidemic gastroenteritis associated with astrovirus, the first case reported in Japan, is described. Not only children (5-6 years of age), but also staff members of a kindergarten were affected. the virus particles detected in stools were 28-30 nm in diameter with a circular outline and had the characteristic star-like configuration which allowed identification as astrovirus. Significant immune responses to the virus were confirmed by immune electron microscopy. Out of 84 children, 43 (54.2%) were affected; the common symptoms were vomiting, abdominal pain, diarrhea, and fever. All the patients recovered completely within 48 hours. Occurrence of gastroenteritis due to contact with these patients was observed in 14 of 43 families.

From among 1,248 stool specimens examined during the 2-year period, February 1979 to February 1981, astrovirus was detected by electron microscopy in 42 specimens from 28 children. Diarrhoea was an invariable clinical feature; vomiting occurred in 18 children, abdominal pain in 7, and mild dehydration in 5. Fourteen of the children with acute diarrhoea were admitted directly to the gastroenteritis unit. The other 14 children developed their acute diarrhoea sometime after hospital admission. Although the excretion of astrovirus was associated with mild gastroenteritis, the presence of other enteric pathogens in 16 of the 28 children limited the degree to which the clinical symptoms could be attributed to astrovirus alone. Transient monosaccharide intolerance lasting 1 to 2 days occurred in 18 children, and cow's milk protein intolerance requiring milk elimination for several months was a sequel in 3 children.

Aeromonas hydrophila gastroenteritis was detected in 12 pediatric patients during a 5-month period. Chief complaints included bloody diarrhea, fever, vomiting, and abdominal pain. Severe symptoms in two patients necessitated hospitalization and supportive care. Phenotypic characteristics associated with enterotoxigenicity of A. hydrophila strains demonstrated that all 12 isolates were cytotoxic to HeLa cells and most were lysine decarboxylase positive (75%). A correlation existed between the presence of the five virulence-associated markers of two isolates of A. hydrophila and the severity of disease. Although the length and symptoms of gastroenteritis varied among all 12 patients, most had self-limiting diarrhea. The frequent occurrence of A. hydrophila gastroenteritis in pediatric patients warrants a greater appreciation of this agent as a significant cause of diarrhea, especially in summer.

The Authors describe a rare case of Yersinia Enterocolitica (Y.E.) infection in a child affected by thalassemia. The onset of the disease was that of an acute enteritis with diarrhea, fever, vomiting and abdominal pain which subsequently evolved in a picture consistent with an acute appendicitis. Laparotomy was then performed and showed a marked suppurative mesenterial lymphadenitis with mild appendicular inflammation and Y.E. infection was suspected. Culture from lymphonodes confirmed the presence of Y.E. sensitive to tobramicin and CTM. The use of these chemiotherapic agents has been followed by a rapid clinical improvement. Our recent experience could suggest some practical considerations: 1) Culture of Y.E. should be routinely performed in all children affected by acute gastroenteritis and particularly in those, above 5 years of age, in which the infection can simulate acute appendicitis. 2) Special attention should be carried out in children affected by thalassemia who can easily present more serious disease often complicated by septicemia. 3) Therapy depends on the form and severity of the disease and should be always guided by in vitro sensitivity test because of the possibility of resistence of Y.E. against the most frequently used antibiotics in septicemia.

Campylobacter fetus ss. jejuni has recently been recognized as a very common cause of gastroenteritis. Symptoms of Campylobacter gastroenteritis include fever, diarrhea, abdominal pain, myalgia and headache. Bloody diarrhea occurs in about 50 percent of patients. This organism is now being isolated more frequently than Salmonella or Shigella in cases of diarrhea. Acute colitis mimicking Crohn's disease or ulcerative colitis on proctoscopic examination and on barium enema x-ray has been described. The drug of choice for therapy is erythromycin.

Outbreaks of acute gastroenteritis occurred in AK and N Primary Schools of Osaka Prefecture early in March and early in November, respectively, 1977. Epidemiological surveys were carried out in both schools with the following results. The morbidity rates were 21.8% (AK) and 8.5% (N) among all pupils, and 41.7% (AK) and 36.8% (N) in special age groups. The main clinical symptoms were abdominal pain (77.2-91.3%), diarrhea (38.4-41.3%) and vomiting (6.5-41.6%). Electron microscopic observations of negatively stained specimens showed that five of 15 fecal extracts obtained from patients in the two schools contained virus particles of 35-40 nm diameter with some black hollows on the surface of complete particles and ten projection-like structures at the edge of empty shells. These morphological characteristics resemble those of calicivirus particles. Immune electron microscopic examination suggested that outbreak in AK School was associated with this virus. Attempts to cultivate the viruses in various cultured cells and in suckling mice were unsuccessful.

In the first year after establishing a gastroenterological center in a vineyard and industrial district with 220.000 inhabitants we examined 1.171 patients. In 36.53% we had diseases in the lower gastrointestinal tract excluding proctological disturbances. We could find out 37 cases of colitis ulcerosa and 42 colorectal cancers. Excluding two cancers in colon transversum and ascendens all the tumors were found by coloscopy. Previously 4 cases of colitis ulcerosa were identified by other methods, clinically or by rectoscopy. In 48.6% of the colitis ulcerosa the transfer was done by reason of blood in the feces. The melaena lingers between 1 month and 10 years. Other presumed diagnoses for transfer to our Institute were gastroenteritis, proctitis, hemorrhoids, fissure or ileitis terminalis Crohn. In some rare cases the supposed diagnosis was salmonellosis or mycosis of the intestinum. In colorectal cancers the main reason for special gastroenterological investigation was the addition of blood to stool, whether microscopically or visible. Abdominal pain or ileus were following in frequency. Clinical symptoms were to be reconstructed in 30.9% for six weeks, in 59% for six months and in 9.5% up to one year. Most of the colorectal tumors (85.7%) were localized distal from splenic colonflexur, mostly in the rectosigmoid and colon descendens (see figure 1). Ambulant coloscopy is a method for quickly and definitive clarification, if the practitioner will refer swiftly.

A prospective study was performed to estimate the frequency of gastroenteritis due to Yersinia enterocolitica in Montreal children and their families. Evidence of bacterial infection was correlated with clinical features and serologic responses. YE was isolated from the stools of 181 (index cases) of 6,364 children with gastroenteritis over a 15-month period; Salmonella was isolated from 280 and Shigella from 68. Median ages were 24, 30, and 41 months, respectively. All but 18 YE isolates were biotype 4, serotype 0:3. YE was not found in the stools of 545 children without gastrointestinal symptoms. Clinical manifestations of the index cases with YE biotype 4, serotype 0:3 (n = 57) included diarrhea (98%), fever (88%), abdominal pain (64.5%), and vomiting (38.5%) with mean durations of 14, 3.9, 7.7, and 2.4 days, respectively. The duration of excretion of YE in the stool ranged from 14 to 97 days (mean 42). Spread of YE occurred in 27 of 57 families studied, involving 15 of 41 children and 19 of 117 adult contacts; approximately one-third of infected contacts developed diarrhea. Agglutination titers of greater than or equal to 200 were demonstrated in all index cases infected with serotype 0:3, with the exception of two very young infants. YE is a frequent cause of bacterial gastroenteritis in Montreal children. The illness is characterized by persistent diarrhea and abdominal pain, prolonged YE excretion in the stools, and moderate communicability.

The role played by Campylobacter jejuni in the origin of infantile bacterial gastroenteritis is important. Diarrhea, often bloody, is dysentery-like. Fever, abdominal pain and vomiting are rarely lacking. Dehydration is exceptional. Spontaneous recovery occurs in about ten days. Campylobacter jejuni is a Gram-negative, oxidase-positive, microaerophilic bacillus. The often typical results of direct morphological examination of the stools, special culture and isolation techniques, the erythromycine sensitivity of the germ, clearly define campylobacteriosis. Its epidemiology is still being investigated.
