Mucoid presentation of acute enterocolitis in children: a hospital-based case-control study.

A hospital-based case-control study was carried out to clarify the characteristics of mucoid presentation of acute enterocolitis in children. One hundred sixty-eight cases of acute mucoid enterocolitis (study population) were compared with 200 cases of watery diarrhoea and 118 cases of blood dysentery (control groups) on the basis of clinical characteristics and findings on stool examination. Study and control groups were comparable with respect to age, body weight and nutritional status. There was no significant difference in clinical characteristics (duration of diarrhoea, stool frequency, presence of vomiting, fever and dehydration) between patients suffering from mucoid enterocolitis and blood dysentery. However, watery diarrhoea patients had significantly high frequencies of vomiting (p=0.00001) and dehydration (p=0.00001). High numbers of microscopic red blood cells (mean +/- SD: 40.8 +/- 16.8) and white blood cells (40.6 +/- 18.0) were present in faecal samples of the patients with mucoid enterocolitis, which is indicative of infection caused by enteroinvasive enteropathogens. Shigella was a commonly identified enteropathogen in patients with mucoid enterocolitis (40.5%) and in patients with dysentery (46.6%), with no statistically significant difference (p = 0.30). Isolation of Salmonella was statistically similar in study and control groups. However, Entamoeba histolytica was detected in significantly high frequency in patients with mucoid enterocolitis as compared to the patients with dysentery (p = 0.0004) and watery diarrhoea (p = 0.00004). Our results indicate that mucoid enterocolitis patients are infected with enteroinvasive enteropathogens, and that stool examination is useful in establishing the aetiological diagnosis.

Adherence, enterotoxigenicity, invasiveness and serogroups in Campylobacter jejuni and Campylobacter coli strains from adult humans with acute enterocolitis.

Two hundred Campylobacter jejuni and Campylobacter coli strains from the same number of adult Swedish patients with acute enterocolitis were tested regarding adherence to and invasiveness in HEp-2 cells and for enterotoxigenicity by the CHO-cell assay. The serogroup characteristics, heat-stable and heat-labile, for each strain were also investigated. Eighty-four percent of the strains were classified as C. jejuni and 16 percent as C. coli. All of the strains were adherent to HEp-2 cells, 39% were invasive and 31.5% enterotoxigenic. We found significantly more invasive strains in the non-enterotoxigenic group than in the enterotoxigenic one. There would seem to be no correlation between enterotoxigenicity or invasiveness and serogroup. The results of this study suggest the existence of multiple mechanisms for C. jejuni- and C. coli-induced diarrhoea and that the mechanisms may differ from one strain to another.

[An epidemic of acute enterocolitis caused by enterotoxigenic Escherichia coli].

In an epidemic of enterocolitis on a military ship which lasted two days, 13 (54%) out of 24 soldiers became ill. The clinical picture was mild with predomination of diarrhoea and abdominal pain, and the troubles in all ill persons ended within 48 hours with administration of symptomatic therapy. Since routinely examined causative agents of infectious diseases were not detected, detailed examination of 13 Escherichia coli strains isolated from stools of the ill persons as well as 8 strains from stools of healthy but exposed soldiers, revealed that 7 of them produced enterotoxins; 5 strains produced heat-labile (LT) and heat-stabile (ST) enterotoxins, and 2 strains ST only. Enterotoxigenic strains were isolated from stools of 5 (38.5%) ill persons and 2 (25%) healthy persons. According to epidemiological investigations, infection was transmitted by secondary contaminated food due to its mishandling. The presented results prove that enterotoxigenic E. coli play a role as a causative agent in epidemics of acute enterocolitis in adults.

Diffusely increased colonic F-18 FDG uptake in acute enterocolitis.

A 60-year-old woman with a remote history of colon carcinoma was studied with F-18 FDG PET imaging 5 days after admission for acute toxigenic enterocolitis. Marked and diffusely increased uptake was noticed throughout the ascending and transverse colon, which was noticed to be edematous and thickened on contrast CT examination. The study emphasizes the need to consider nonneoplastic entities, such as enterocolitis in the differential diagnosis of intensely hypermetabolic colonic lesions on F-18 FDG PET examinations.

Acute enterocolitis in a human being infected with the protozoan Cryptosporidium.

A 3-year-old child with severe acute self-limited enterocolitis was found on rectal biopsy to be infected with the protozoal parasite Cryptosporidium. This organism is known to infect a variety of vertebrates, but this is the first report of infection by Cryptosporidium in a human being. Both light and electron microscopic findings in the rectal biopsy are reported. It is suggested, on the basis of the severity of the clinical symptoms, and on the pathological changes in the rectum, that the organism in this case is likely to have been the cause of the enterocolitis and thus to have been a pathogen rather than a commensal. The source of the infection in this child could not be established. The value of signoidoscopy and biopsies is noted in this condition and as a general method for determining the etiology of a gastrointestinal infection in cases where other studies are negative.

[Non-obstructive necrotizing acute enterocolitis (apropos of a case report) )University Hospital Center Kamenge-Bujumbura)].

The authors report on a new case of acute necrotic non obstructive enterocolitis. Discussion is mainly centered on the nosological framework of this uncommon affection, occurring in an infectious background, and on its etiopathogenetic mechanism. Several hypothesis are formulated. Because of the seriousness of its prognosis, it is emphasized on the necessity of a rapid surgical intervention.

[The characteristics of acute enterocolitis and Escherichia infections in the Ukrainian SSR].

A nosogeographic study in the Ukrainian SSR revealed 3 zones of gastroenterocolitis morbidity: low, average and above average. Also cartographically were determined 3 Escherichia infection morbidity zones in children under 1 year of age. Conformity of pathogenic Escherichia serogroups (025, 026, 055, 0119 and others) among most humans, animals and environment suggest circulation of pathogens by the cycle: man (patient, carrier)--environment--animals (birds) and vice versa.

Clostridium difficile and acute enterocolitis.

Clostridium difficile belonging to groups not normally detected in infancy was the only potential pathogen detected in the stools of two infants with severe enterocolitis. Further information regarding the virulence of this organism was obtained by use of a recently introduced typing scheme.
