Collagenous colitis is a newly recognized entity presenting clinically as chronic watery diarrhea and histologically by a thickened subepithelial collagenous band in colonic biopsies. We report the case of a middle aged woman affected of acute diarrhea in whom, after ruling out its main etiologies, the diagnosis of collagenous colitis was made.

Several clinical symptoms and laboratory findings from 352 pediatric patients, seen in the Emergency Room for acute diarrhea, were evaluated in order to develop a method to predict the bacterial etiology of the diarrhea. According to the microbiology findings, the patients were classified into two groups: proven bacterial diarrhea and diarrhea of another etiology. Among all clinical symptoms recorded, only the following were found to be useful for the prediction score: fever greater than 38 degrees C (8 points), fecal mucus (8 points), over fecal blood (6 points) and the presence of fecal leukocytes in a wet mount (7 points). An alternative score useful for outpatients was developed that does not include a score for the wet mount. When the fecal leukocyte score was included and a cutoff value of 20 points was assigned, a sensitivity of 74% and a specificity of 83% were obtained. When the score for the fecal leukocytes was excluded and a cutoff value of 13 points assigned a sensitivity of 84% and specificity of 59% were obtained. These rapid and simple scores may be useful methods for predicting acute bacterial diarrhea in children.

In infants and children, the treatment of acute diarrhoea with glucose-based electrolyte solutions results in rehydration but does not reduce the severity and duration of diarrhoea. In german-speaking countries, rice- and carrot-based solutions have a long tradition in the treatment of diarrhoea and may also reduce stool output and the duration of diarrhoea. Therefore, we evaluated the efficacy and safety of a carrot-rice-based rehydration solution (Na 57 mmol/L, n = 70) and two conventional glucose-based solutions with high or low sodium concentrations (Na 90 mmol/L, n = 48 or Na 55 mmol/L, n = 60) in a prospective study. The study subjects were Pakistani boys and girls between 3 and 48 months of age with mild or moderate dehydration. We measured duration of diarrhoea, fecal and urine output, fluid intake and serum electrolytes. The duration of diarrhoea was significantly lower (p less than 0.05) in the group receiving the carrot-rice based rehydration solution (59.5 +/- 30.9 h) than in the groups receiving the high-Na (75.5 +/- 30.5) and low-Na (74.8 +/- 32.5) glucose-electrolyte solutions. The mean fecal output (p less than 0.01) and fluid intake (p less than 0.001) were also significantly lower in the infants and children receiving the carrot-rice-based rehydration solution. No major electrolyte imbalances were observed in the three groups. We conclude that the carrot-rice-based rehydration solution was safe and more effective than two conventional glucose-electrolyte solutions in the rehydration of infants and children with acute diarrhoea.

Between June 1989 and January 1990 in Ethiopia, health workers collected 2 gm diarrhea samples from 100 patients, 2-48 months old, at the oral rehydration unit of the Gondar College Medical Sciences Hospital to test for the presence of Cryptosporidium species' oocysts. Laboratory personnel used Loeffler's alkaline methylene-blue solution to isolate oocysts in 9 children. 6 of these children were 12 months old. None of the children with Cryptosporidium oocysts exhibited signs of severe protein energy malnutrition, but 31 other children did exhibit these signs. The presence of oocysts in the 9 children did not necessarily indicate that Cryptosporidium species were the only causes of their acute diarrhea. The 9% isolation rate may be an underestimate, because Baxby and Blonde have demonstrated that safranin-methylene blue yields a better Cryptosporidium oocyst isolation rate than does Loeffler's alkaline methylene-blue. A well-designed study is needed to determine the true prevalence of cryptosporidiosis, to describe its clinical profile, and to define its association with other diarrhea-causing enteropathogens and its association with malnutrition.

In a case-control study we evaluated the role of maternal behaviour, as reflected in maintenance of breast feeding and the use of oral rehydration therapy (ORT) at home during acute diarrhoea, in preventing dehydration in infants and young children. A systematic 5% sample was taken of all children aged 1-35 months attending the treatment centre of the International Centre for Diarrhoeal Disease Research, Bangladesh, with acute watery diarrhoea of six days or less between August 1988 and September 1989. There were 285 children with moderate or severe dehydration as cases and 728 with no dehydration as controls in the study. In a multivariate analysis using a logistic regression model we showed that withdrawal of breast feeding during diarrhoea was associated with a five times higher risk of dehydration compared with continuation of breast feeding during diarrhoea at home. Lack of ORT with either complete formula or a salt and sugar solution at home was associated with 57% higher risk of dehydration compared with receipt of a reasonable amount of ORT after controlling for several confounders. The confounding variables--that is, lack of maternal education, history of vomiting, high stool frequency, young age and infection with Vibrio cholerae 01--were also shown to be risk factors of dehydration. Health education programmes should promote continued breast feeding and adequate oral rehydration therapy for infants with acute diarrhoea at home.

Diarrhoea is defined as the frequent passage of loose or watery stools. Most patients can easily recognise and accurately define acute diarrhoea as an abrupt change in their bowel habits. Chronic or recurrent diarrhoea is more difficult for the patient to define, since it may mean malabsorption, tenesmus or true diarrhoea. Serious disorders not to be missed include neoplasia, AIDS, various serious infections such as amoebiasis, and inflammatory bowel disease.

Enterobacteriaceae isolated from the duodena of Peruvian children with persistent diarrhea (PD) have been examined for virulence factors and compared with Enterobacteriaceae isolated from children with acute diarrhea, those convalescent from PD and diarrhea-free controls. Escherichia coli were isolated from 42 of 186 (23%) of the aspirates. All 11 children with PD in whom multiple E. coli colonies were examined were colonized by a single serotype. DNA probes identified enterotoxigenic E. coli in 2 of 89 (2.2%) PD aspirates and 2 of 38 (5.3%) acute diarrhea aspirates and enteroaggregative E. coli in one PD and one control aspirate. Strains positive with the enteropathogenic E. coli adherence factor probe were identified from 2 of 89 (2.2%) patients with PD and 1 of 34 (2.9%) controls. A subset of 12 E. coli strains failed to show adhesion to human duodenal enterocytes although 5 of 9 showed sparse but polar attachment to ileal cells from a child with short bowel syndrome and PD. Three of 10 Enterobacteriaceae (two E. coli, one Klebsiella species) caused diarrhea in the reversible ileal tie adult rabbit model. Colonization with virulent Enterobactericeae did not explain the majority of episodes of PD. Examination of these duodenal bacteria in the rabbit model revealed some that caused diarrhea but were not recognized pathogens.

A longitudinal study of diarrhea was carried out from May 1988 to April 1989 by household surveillance of 705 children less than 5 years old in rural Bangladesh. Stool samples were examined for enteric pathogens at the beginning of each diarrheal episode. For persistent episodes, stool examination was repeated on days 15-17 of the illness. For each case of persistent diarrhea, stool samples from age-matched acute diarrheal and healthy controls were examined. Compared with healthy controls, cases of diarrhea were associated with Shigella species (P = .07) and rotavirus (P less than .05). Diffusely adherent Escherichia coli (P less than .05) and cryptosporidia (P = .07) were the only enteropathogens associated with persistent diarrhea in comparison with acute diarrhea. No more than 15% of children had the same class of pathogen identified from stool on both days 1-3 and days 15-17, indicating that persistent infection was uncommon. However, a different enteropathogen was frequently found on days 15-17, suggesting that sequential infection may be a cause of persistent diarrhea.

Forty-six male children 12-59 months old (27 malnourished and 19 with normal nutrition) admitted for acute water diarrhoea of less than 48 hours' duration were studied. Using a metabolic balance and separate collections of urine and stools over each 6-hour period, balance studies were carried out up to 48 hours. Blood, stool, and urine samples were analysed for sodium and potassium levels. Serum cortisol levels were determined using radio-immunoassay in a subsample of six normal and five malnourished children. Malnourished children lost more sodium in their stools and urine during diarrhoea, so that they had significantly diminished gut net sodium balance and significantly diminished total body sodium balance. Significantly higher levels of serum cortisol were observed initially on admission among children with malnutrition. This study demonstrated that malnourished children had poorer sodium balance during acute diarrhoea.

A commercial dog breeding unit experienced problems with acute diarrhoea, often haemorrhagic, in young German Shepherd Dog litters. No aetiologic diagnosis had been made. In order to determine whether coccidial infections were implicated, a survey was conducted to ascertain shedding of oocysts by dams, acquisition of coccidial infection by neonatal pups and to determine whether bouts of diarrhoea were associated with peak oocyst production. Oocysts of Isospora canis and I. burrowsi/I. ohioenis were recovered from 26.0% of faecal specimens from bitches and from 51.7% of similar specimens from litters. No association between shedding of oocysts by bitches and their litters could be demonstrated, nor was there consistent association between bouts of diarrhoea and peaks of oocyst shedding.
