The hemolytic-uremic syndrome consists of microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia following a prodromal illness of gastroenteritis or upper respiratory infection. The syndrome can present in dramatic fashion with severe abdominal pain and signs of peritonitis suggesting an acute surgical crisis. In a series of 25 patients, 40% had abdominal pain, 25% had abdominal tenderness, and 20% had peritoneal signs. Clues to diagnosis in the early stages of the acute illness were mild to moderate hypertension, abnormal peripheral blood smear, anemia despite dehydration, and proteinuria. Significant abdominal pain and x-ray evidence of colitis may occur before development of typical laboratory findings, and these were evident in at least one case. Three patients underwent laparotomy for suspected bowel perforation. Colitis without perforation was found in all cases. In the absence of documented perforation, toxic megacolon, or intussusception, the decision to perform laparotomy in patients with hemolytic-uremic syndrome who have signs of peritonitis must be individualized. Failure to recognize the underlying renal problem can lead to serious errors in fluid and electrolyte management and delay of appropriate therapy.

A 58 year old Chinese male, one week after arriving in Canada from Hong Kong, presented with acute abdominal pain and diarrhoea which was rapidly followed by Escherichia coli infection causing septicaemia and meningitis. His past history revealed bronchial asthma for 15 years treated with steroids. At laparotomy, 7 days after the onset of symptoms, he was found to have extensive haemorrhagic infarction of the small bowel and right colon. Examination of the fibrosed mesenteric vessels revealed numerous filariform larvae of Strongyloides stercoralis, within the walls, and in all layers of bowel wall. The role of the parasite in the production of obliterative arteritis in this fatal case of haemorrhagic enteropathy is discussed. Clinical strongyloidiasis, in uncomplicated cases, varies from mild to severe with gastroenteritis, nausea, colicky abdominal pain, electrolyte imbalance and symptoms of malabsorption syndrome (MARCIAL-ROJAS, 1971). In malnourished individuals and patients with debilitating infections, either newly acquired or asymptomatic latent infection with S. stercoralis can assume severe dimensions (BROWN and PERNA, 1958; HUGHTON and HORN, 1959). Similarly, in patients on steroid (CRUZ et al., 1966; WILLIS and MWOKOLO, 1966; NEEFE et al., 1973) and immunosuppressive therapy for lymphomatous diseases or deficient in immune response (ROGERS and NELSON, 1966; RIVERA et al., 1970), systemic strongyloidiasis is often fatal. The increased frequency of auto-infection in such patients with a breached immune barrier is, however, unclear. Further complications of this infection due to severe enterocolitis result in sepsis, bacteraemia and meningitis (BROWN and PERNA, 1958; HUGHTON and HORN, 1959). This paper presents a fatal case of S. stercoralis infection which illustrates an uncommon if not unique, mechanism in its production of haemorrhagic enteropathy leading to sepsis and death.

Of 34 non-bacterial gastroenteritis outbreaks which occurred at day-care centers, kindergartens, elementary and secondary schools in Tokyo during the period from February 1985 to June 1991, 28 outbreaks from which small round structured viruses (SRSV) were detected in the patients' stool specimens by electron microscopy were subjected to an epidemiological investigation. The outbreaks tended to occur frequently in the cold season; twenty-two (79%) of these outbreaks from November through April. Though detailed epidemiological informations was not obtained from all outbreaks, the common source of infection were presumed to be present in many of the outbreaks, judged from the incidence as to time course of patients. Food doubted to be incriminated as transmission vehicles in these outbreaks was served at schools, kindergartens, and lodgings. In some outbreaks, SRSV was detected from stool specimens of food handlers, or they were seroconverted to SRSV, suggesting that food was incriminated as a transmission vehicle. The symptoms of patients differ slightly from age to age: in the age range of 0 to 6 years, vomiting 90%, fever 41% and diarrhea 32%; in the 6 to 12 year-olds, nausea 61%, vomiting 48%, abdominal pain 65%, diarrhea 20% and fever 29%; and in the 12 to 15 year-olds, nausea 69%, vomiting 42%, abdominal pain 60%, diarrhea 30% and fever 34%. The lower the age of patient vomiting was more frequently observed. In these lower age groups, the frequency of nausea and vomiting tended to exceed that of diarrhea.

A retrospective study is discussed, in which the disorder of pancreatic enzymes in hospitalized patients because of an acute infectious gastroenteritis is analyzed. Of 30 cases, 15 showed a raise in lipase levels, being over 1,000 IU in five of them. There was no associated raise in amylase levels. Patients with high lipase levels did not show more fever, leucocytosis nor disorders on the hepatic enzymes, in comparison with those patients with normal lipase levels. Mean age was slightly lower in patients with high lipase levels than in those with normal lipase. Chronic diseases are not a predisposing factor to suffer pancreatic complications in patients with gastroenteritis. There was no case with intense abdominal pain which would suggest a pancreatitis, and a raise in lipase did not modify the evolution of the gastroenteritis.

Campylobacter jejuni/coli (CJC) was isolated from the stools of 82 (1 per cent) of 7369 children with gastrointestinal symptoms during a 2-year period. Among 1130 control children, CJ was isolated from the stool of one (0.09 per cent). The peak incidence of CJC associated gastroenteritis was in the winter. Seventy-six per cent of the patients were 4 years of age and younger with the highest incidence (56 per cent) in children 2 years old and younger. The most common presenting symptoms and signs were diarrhoea (95 per cent), anorexia (71 per cent), abdominal pain (70 per cent), high fever (57 per cent), and frank blood in stools (48 per cent). In five (6 per cent) patients CJC isolates were resistant to erythromycin. In all patients CJC infection was self-limited and the majority of patients required only supportive therapy.

Primary pneumococcal peritonitis is an uncommon condition 1st identified in 1885. It occurs when peritoneal inflammation is present in the absence of an intraabdominal source of infection. In the preantibiotic era, the condition accounted for 2% of childhood abdominal emergencies largely among girls aged 2-10 years. Mortality was 42-100%, with death sometimes occurring within 48 hours of the onset of symptoms. This condition now present in female adults, is associated with IUD use, and is comparatively common in India. Consideration should therefore be given to the existence of primary pneumococcal peritonitis when diagnosing and managing abdominal emergencies. The pneumococcus may enter the peritoneal cavity via the female genital tract, blood, or through transmural spread from the gastrointestinal tract. No evidence supports a relationship between type of IUD and/or length of time in place, and the onset of peritonitis. Given pneumococcus' commensal existence in the upper respiratory tract, urogenital sex may facilitate its entrance to the peritoneal cavity through the female genital tract. Abdominal pain, diarrhea, and vomiting generally present, while the patient may also be pyrexial and dehydrated. In diagnosing this condition, the practitioner may confuse it with acute appendicitis, pelvic inflammatory disease, or gastroenteritis if in the early stages of peritonitis. Diagnosis is often confirmed only thorough laparotomy, but abdominal paracentesis and/or abdominal ultrasound may also be employed as diagnostic aids. Laparotomy and a regime of antibiotics is the preferred treatment. 2 case studies are discussed.

A total of 27,480 stool specimens from 15,548 patients with gastroenteritis were analyzed for bacterial enteropathogens during a 4-year period between 1986-89 at a major referral center in Saudi Arabia. Bacterial pathogens were isolated from 1,152 patients, Salmonella being the most frequent, followed by Campylobacter, Shigella, and Aeromonas hydrophila. The latter bacterium was found in 58 patients; seven of them were associated with other enteric pathogens, but A. hydrophila was the only organism in 51 patients. All had gastrointestinal symptoms, the most common being diarrhea (92%), followed by abdominal pain (68%), fever (37%), and vomiting (27%). Stool specimens from 1,368 control patients were negative for A. hydrophila.

In March 1989 a large outbreak of acute gastroenteritis occurred simultaneously among schoolchildren and teachers at nine elementary schools in Toyota City, Japan. Illness was observed in 3236 (41.5%) of 7801 schoolchildren and 117 (39.4%) of 297 teachers. The main clinical symptoms were diarrhoea, vomiting, nausea and abdominal pain. Gastroenteritis was significantly associated with the consumption of school lunch served by one particular lunch preparation centre. One food handler at the centre suffered from gastroenteritis during the outbreak. Small round structured virus (SRSV) was detected in 4 of 8 stool specimens from sick persons. The school lunch contaminated by the infected food handler is the most probable source of this outbreak due to SRSV.

An outbreak of gastroenteritis involving a total of 256 patients (49.7%) among 515 persons occurred at a primary and secondary school in Agatsuma Town, Gunma Prefecture between the 23rd and 28th of June 1988. The majority of the cases occurred within the first 4 days. The main symptoms were abdominal pain (81.6%), diarrhea (57.0%) and headache (40.2%). In most cases, the stools were watery and occasionally mucous. Although food-borne infection was strongly suggested epidemiological evidence did not incriminate any foods as the cause of the outbreak. In the bacteriological study on stool specimens from 25 patients, Escherichia coli O167:H9 was isolated from 20 of these specimens, virtually in pure culture. The isolates of the E. coli serovar were negative for recognized diarrheagenic virulence properties: production of heat-labile and heat-stable enterotoxins, enteroinvasion, and production of Shiga-like toxin. When the HEp-2 cell-adherence test was used, however, they exhibited localized adherence. All the strains were demonstrated to carry 56 Md plasmids that presumably mediate the production of the adherence factor.

Between August 24-October 20, 1985, an outbreak of acute diarrheal disease occurred among 1833 children in Imphal, Bishenpur, and Thoubal districts in Manipur State in India for an overall attach rate of 2/1000. 17 children died, a case fatality rate of 9/1000. Hospital and health center personnel treated 1711 cases with rehydration therapy (oral or intravenous fluids). Local, mainly unqualified, practitioners treated the remaining 122 cases with antidarrheal drugs. Children treated at home were more likely to die than those treated at health facilities (case fatality rates 0.6% vs. 4.9%; p.001). Nevertheless these case fatality rates were lower than those in a 1973-1974 outbreak of gastroenteritis in Manipur, perhaps because the health authority distributed oral rehydration solution packets during this 1985 epidemic. The leading symptoms were watery diarrhea (82.5%), vomiting (67.5%), and abdominal pain (37.5%). Children 5 years old tended to experience severe dehydration more so than younger children (31.3% vs. 12.5%). 58.8% of hospitalized cases were older children who suffered the highest death rate. (1.9%). Peak admissions occurred the last week of September ending on October 2. Yet during the decline phase, the admission rate of children 2 years old rose. 25.3% of cases sampled recovered V. cholerae with the highest isolation rate (30.8%) found in older children and adults. 50% of fecal samples of children 6-23 months old tested positive for rotavirus. The researchers did not find any obvious epidemiological link between the 3 areas. They concluded that the rotavirus epidemic which peaked the week after that of cholera represented the beginning of the usual rotavirus diarrhea season.
