The role of shigella infection in childhood gastroenteritis was studied over a 2-year period. Shigella species were found in the faecal specimens of 70 (1%) of 7369 children with gastroenteritis, but in only 1 (0.1%) of 1130 controls. S. flexneri was the commonest isolate (51%), followed by S. sonnei (37%). Most shigella species were isolated during the winter. The prevalence of shigellosis was highest for children 1-5 years of age but equal for both sexes. Fever, abdominal cramps, vomiting, and bloody diarrhoea were the predominant clinical features. Of the shigella isolates, 73% were resistant to cotrimoxazole, 43% to ampicillin, and 41% to chloramphenicol. One-third of isolates were resistant to greater than or equal to 3 antibiotics. All isolates were susceptible to nalidixic acid. The illness was mild and self-limiting and most patients recovered without antimicrobial 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.

For a minimum of one month (mean, 54 days), 287 infants and children less than 8 years of age were fed an isolated soy-protein formula. Prior to entry into the study, a cow's milk formula was being fed to 71%, a soy formula to 9%, and cow's milk or other formulas to 20%. Intolerance to cow's milk was reported in 35% of the patients, symptoms indicative of cow's milk intolerance in 23%, diarrhea or gastroenteritis in 18%, a family history of allergy in 13%, and insufficient weight gain, intolerance to other formulas, or constipation in 11%. The patients showed normal increases in weight and length during the study. A significant decrease in the following symptoms were reported in the patients from before to after treatment: abdominal cramps, bloating or gas, colic, diarrhea, fussiness, rashes or eczema, spitting up, waking up crying at night, wheezing, and vomiting. It is concluded that, while receiving soy formula, infants and children continued to thrive normally and that the formula was well tolerated. After receiving soy formula, the frequency of undesirable feeding-related symptoms was reduced in the majority of infants and children.

Over a 5-year period, lymphocytic/plasmacytic gastroenteritis was diagnosed in 14 cats. Purebred cats were affected significantly (P less than 0.025) more often than nonpurebred cats. Mean age at onset of clinical signs was 6.8 years (range, 1 to 13 years); 11 cats were male. Vomiting and weight loss, each reported in 10 of 14 cats, were the most common clinical signs. Diarrhea was reported in 7 of 14 cats. Alopecia was found in 4 of 14 cats. High hepatic enzyme activities and low plasma protein concentrations were frequent biochemical findings. Hyperemia, hemorrhage, and a roughened or "cobblestone" mucosa were visualized by endoscopy in only 2 of 8 cats with duodenal disease and in 2 of 5 cats with gastric disease. Lymphocytic/plasmacytic inflammation was detected in biopsy specimens from the stomach or duodenum or both in all cats; the duodenum was affected most commonly. Degree of inflammation frequently varied among gastric, duodenal, and colonic specimens from the same cat. Glucocorticoid treatment and dietary management adequately controlled clinical signs in 7 cats, but treatment was ineffective in 6 cats, 5 of which were euthanatized because of severity of clinical signs.

The epidemiology of rotavirus gastroenteritis was studied in the Matsuyama district from January to May 1988. Among strains of rotaviruses detected 46 showed the group C-specific PAGE pattern of virus RNA. Group C rotavirus gastroenteritis occurred following an epidemic of group A rotavirus infection, primarily in children aged 4-7 years but rarely in those aged 0-1 years. This was seriologically confirmed after the epidemic. Unlike the previous strains detected in Matsuyama in 1985-1986, PAGE of the RNA showed arrangement of the 5th, 6th and 7th segments at similar intervals, suggesting virologic variation. The symptoms of fever, diarrhea and vomiting were milder than in group A rotavirus infection used as a control.

Between December 9, 1988 and January 28, 1989, there were four outbreaks of acute gastroenteritis in Saitama prefecture. Eighty-two of 123 persons (67%) attending four banquets in restaurants became ill: 44 cases attending three banquets were related to eating raw oysters, and 38 attending one banquet to eating sashimi. The most common symptoms were nausea, diarrhea, abdominal cramps, and vomiting. Average incubation periods were 29 to 32 hours long. Bacteriologic analysis of stool specimens did not reveal causative agents. Small round structured viruses were detected in fecal specimens from 19 of 39 ill persons (49%) by electron microscopy. In one of four outbreaks, the formation of antibody to small round structured virus in paired serum samples was detected by western blot test. Small round structured viruses were implicated as the etiologic agents in four outbreaks of acute gastroenteritis.

In December 1989, an outbreak of gastroenteritis associated with cake consumption occurred in a day-care center with 60 children and 12 staff in Saitama prefecture. Children were served cakes at the Christmas party held in the day-care center and ate them with their families. Thirty-three of the 59 children (56%), 16 of the 74 families (22%) and 1 of the 10 staff (10%) eating the cakes became ill. Illness consisted primarily of nausea, vomiting, diarrhea and fever; the median incubation period was 31 hours. Bacteriological analysis of stool specimens did not reveal a causative agent. Small round structured viruses (SRSV) were detected in fecal specimens from 10 of the 17 ill children (59%) and 2 of the 6 ill families (33%) by electron microscopy. Cakes were purchased from a bakery where an employee who prepared the cake denied symptoms, and SRSV was not detected in the fecal specimen from the employee. Thus, it was not determined that the cake was contaminated by a food handler.

During the period December 1984 to October 1988, adenoviruses (Ads) were isolated on 119 occasions (1.6%) from stool samples of patients with gastroenteritis. By DNA restriction analysis, 85 enteric adenoviruses (EAds) were identified. Sixty-seven patients with these infections were studied, of whom 18 had Ad40, 30 had Ad41 and 19 had untyped Ad infections. The incidence of Ad infection was high in children between 6 and 11 months of age. The illness was characterized by watery diarrhea (whitish in one third of patients), continuing for a mean of 4.5 days, and vomiting, which occurred more often in patients with EAds than in other types of infection. Diarrhea, fever and vomiting were seen significantly more frequently in patients with Ad40 than in Ad41 infection. Diarrhea and vomiting were also seen significantly more frequently in patients with EAds than in Ads infection. Diarrhea, fever and vomiting were observed more frequently in patients with rotavirus than EAds infection.

Infection with small round structured viruses (SRSV) usually causes an acute, but short-lived, attack of gastroenteritis in which vomiting is a prominent feature. Most documented outbreaks have occurred in institutional and catering establishments and infected food handlers are often implicated. Reports of SRSV infection have risen substantially during the last decade partly due to an increase in the number of laboratories able to examine samples for this organism. Ascertainment is likely to remain low, however, until a sensitive, simple, reliable and economical method of detection becomes routinely available.

Out of 317 human gastroenteritis cases studied between August 1988-August 1989, two atypical antigenically distinct rotaviruses (pararotaviruses) were detected in faecal samples among 19 rotaviruses shedding children from Misiones province, North-Eastern Argentina. A 1 3/4 year old girl a 3 years old boy, both with vomiting and normal temperature, shed these atypical rotaviruses. Their morphology by electron microscopy was identical to other rotaviruses; they contained 11 double-stranded RNA segments detected by polyacrylamide gel electrophoresis and failed to react with the antibody directed against the rotavirus group specific antigen (Rotazyme II ELISA). The electrophoretic migration of these RNAs (electropherotype) in polyacrylamide gels did not coincide with the typical pattern of distinct size classes observed in most human rotaviruses reported, instead, they appeared to be related to patterns of rotaviruses group C.
