Clinical features of infantile diarrhea were studied among 603 infants from birth to 12 months of age to determine the predominant clinical feature(s) seen in infantile diarrhea associated with a specific enteric pathogen. Among the major clinical features, fever was most often seen in diarrhea due to Yersinia spp. (61.5%) followed by that in rotavirus (26.1%). Vomiting was mostly associated with Vibrio cholerae infection (90.9%) and shigellosis (64.6%). Dehydration was predominant in Vibrio cholerae (90.9%) and Salmonella (84.9%) infections. Bloody diarrhea was mostly due to Shigella infection (74.3%). As regards diarrhea with multiple pathogens, vomiting and dehydration were most frequent with Campylobacter+Enteropathogenic Escherichia coli (EPEC) (88.9% and 77.8%, respectively), while fever was more common with rotavirus+Shigella+Escherichia coli and rotavirus+Giardia. Infection with invasive organisms lead to vomiting, 4-10 stools per day and dehydration significantly more often as compared to infections with non-invasive organisms. Similarly more stools of patients infected with invasive organisms showed presence of blood and more than 5 leukocytes/HPF as compared to those infected with non-invasive organisms.

We report 45 pediatric cases of Yersinia pseudotuberculosis infection confirmed by stool culture between May 1993 and June 1994. In 41 (91.1%) cases there had been contact with untreated well or mountain water. Y. pseudotuberculosis was also isolated from 4 samples of mountain spring water thought to be the sources of infection. During the course of the illness, acute renal failure (ARF) developed in 6 patients (13.6%). The age distribution of the ARF group (12.3 +/- 1.2 years) was significantly different from the non-ARF group (8.0 +/- 3.2 years). The serogroups of Y. pseudotuberculosis isolates from stool samples were 5 (n = 30) and 4 (n = 15). Isolates from the water samples were all serogroup 5. The main symptoms of both groups were fever, rash, abdominal pain, and vomiting. ARF developed between the 2nd and 14th days (mean 6 days) after the onset of fever, and oliguria (< 400 ml/m2 per day) developed in 3 patients (3/6, 50%) immediately after their fevers had subsided. ARF underwent a benign course, with complete recovery within a maximum of 4 weeks (mean 10.2 days), with 1 exceptional patient requiring hemodialysis. Renal biopsy showed evidence of tubulointerstitial nephritis. Y. pseudotuberculosis should be included as one of the causes of acute interstitial nephritis causing ARF in children, especially when the children have histories of drinking untreated water in endemic areas.

Three children were diagnosed as having acute renal failure due to acute tubulointerstitial nephritis (TIN) associated with Yersinia pseudotuberculosis infection. The kidneys were observed ultrasonically during the disease course. The subjects presented with remittent fever, vomiting or diarrhea, and nonoliguric acute renal failure with sterile pyuria and tubular reabsorptive dysfunction. Ultrasound examination delineated marked enlargement of the kidneys with diffuse hyperechogenicity in the cortex, suggesting the diagnosis of TIN. The renal swelling was marked in the descending order of width, depth and length, respectively, and reached more than 200% in volume in 1 of the children who was examined at the culminating stage of acute renal failure. The enlarged kidneys reduced in size in parallel as the elevated serum creatinine levels decreased. However, the enlarged kidneys did not seem to return to their original sizes: the kidney size in 1 of the children remained well above the upper allowance limit of the body-height-related normals and in the other 2 they were only a little smaller than the upper limits. These ultrasound findings should help with the diagnosis and follow-up of the disease.

Eleven patients with Yersinia enterocolitica infections were identified in the Upper Valley of New Hampshire and Vermont during October and November of 1995. Three children presented with an appendicitis-like picture. Two underwent appendectomy, one of whom was the outbreak's index case. Both appendectomy patients presented with lower abdominal pain, fever, vomiting, and a right lower quadrant mass associated with leukocytosis. Both had terminal ileitis, and in both, cultures of peritoneal fluid and a mesenteric lymph node grew Y. enterocolitica. Even during an outbreak there is no consistently reliable nonoperative way to separate a sporadic case of appendicitis from one whose appendicitis-like symptoms are due to Yersinia. In addition, a small percentage of Yersinia patients will present with true appendicitis as a complication of their disease.

A 31/2-year-old girl presented with persistent abdominal pain, fever, vomiting, and diarrhea accompanied by rash, oral ulceration, anemia, and an elevated sedimentation rate. Initial evaluation revealed no pathogens and was extended to include abdominal ultrasound and computed tomography showing marked ileocecal edema and mesenteric adenopathy. Colonoscopy revealed focal ulceration from rectum to cecum with histology of severe active colitis with mild chronic changes. Enteroclysis demonstrated a nodular, edematous terminal ileum. Because of the patient's clinical deterioration despite antibiotics, these features were construed consistent with Crohn's disease, and glucocorticoid therapy was begun. By the ninth hospital day, admission cultures grew Yersinia enterocolitica, and trimethoprim/sulfamethoxazole was begun followed by prompt clinical improvement. The delay in diagnosis afforded an unusually comprehensive clinical description of the presentation and diagnosis of Yersinia enterocolitis in childhood.

The incidence of astrovirus infection in children less than 10 years of age with gastroenteritis in the city of Zaragoza, Spain, was analysed during a 12-month period. A total of 718 stool samples obtained from 534 children were examined. In 401 samples no routinely searched for pathogenic organism was detected; these specimens were then tested for the presence of astrovirus antigens. Astrovirus was detected in the samples of 15 (5.5%) patients, a detection rate similar to that recognised for Yersinia enterocolitica and Cryptosporidium spp. All children with confirmed astrovirus infection had diarrhoea (median duration, 9 days), 11 experienced loss of appetite, 5 vomiting, and 4 fever. The incidence of astrovirus infection reported here indicates that Spanish children suffering from gastroenteritis should be routinely screened for the presence of astrovirus.

The high-pathogenicity island (HPI) of Yersinia has been observed in 93% of 60 enteroadhesive Escherichia coli strains and 80% of E. coli strains isolated from blood samples. In the present study we investigated 671 fecal samples from patients with diarrhea in Shandong Province, China, and isolated HPI-harboring E. coli from 6. 26% of the samples. The isolation rates for patients with diarrhea in three age groups, 10 to 20, 30 to 40, and 50 to 60 years, were 6. 70, 12.35, and 10.81%, respectively. Therefore, HPI-harboring E. coli is the third most frequently isolated enteric pathogen from patients with diarrhea. Vomiting and abdominal pain were recorded for 33.33 and 66.67% of the patients, respectively. Stools with blood were observed for 9.52% of the patients. Twenty-four of 42 (57%) patients experienced a temperature over 37.4 degrees C. These observations indicate that HPI-harboring E. coli is one of the major causes of diarrheal disease in China and that the clinical symptoms caused by HPI-harboring E. coli differ from those caused by enteroadhesive E. coli.

Between February 1992 and January 1993 different Campylobacter spp. were isolated from 86 (13.7%) of 630 patients with diarrhoea at Tikur Anbessa and Ethio-Swedish Children's Hospital, Addis Ababa, Ethiopia. In the same study population, Shigella spp. were found in 11.7% and Salmonella spp. in 3.8%. Campylobacter spp. were found in all age groups, but the majority were isolated from children less than five years of age (68.6%). Only 2 (0.9%) of 220 controls had campylobacter in their stools. Of the campylobacters that were differentiated at species level, Campylobacter jejuni accounted for 82.4% and Campylobacter coli for 17.6% of the isolates. Yersinia enterocolitica was not isolated from any tested stool specimen. More patients (53.1%) presented for investigation of diarrhoea during the months of April through July than during other parts of the year but there was no significant difference in the frequency of isolation of the three enteric pathogens studied during this period as compared to other months of the year. In 12 of the patients infected with Campylobacter spp., Shigella spp. or Salmonella spp. was concomitantly isolated from their stools. The most common symptoms and signs in both adults and children were watery diarrhoea in 82.4%, low grade fever in 78.4% and frequent vomiting in 45.9%. Dehydration ranging from mild to severe was observed in 25.4% of the 55 children with campylobacter infections. Of the 55 children 67.2% had signs of malnutrition and most of them (47.2%) were underweight. This study indicates that Campylobacter spp. are an important cause of diarrhoea both in adults and children in Addis Ababa, and should be considered routinely in the diagnosis of patients with diarrhoea.

The present study, conducted from March 1998 to July 2000, determined the etiology of acute diarrhea in 253 young children and infants from Cartagena and Sincelejo, Colombia. In 253 stool samples, the following enteric pathogens were recovered: rotavirus type A (36.6%) as the major agent, Salmonella spp (9.0%), Shigella spp (8.0%), enteric pathogenic Escherichia coli (6.0%), enteric hemorragic Esc. coli (2.8%), Providencia alcalifaciens (2.8%), Aeromonas hydrophila (2.0%), Yersinia enterocolitica (0.8%), Entamoeba hystolitica (10%), Giardia lamblia (4%), Endolimax nana (3.2%), Ascaris lumbricoides (2.8%), Ent. coli (1.2%), Balantidium coli (0.8%), Blastocystis hominis (0.8%), Dypilidium caninum (0.4%) and hook worm sp. (0.4%). Infection with more than one pathogen occurred in 96 (37.9%) patients. Rotavirus and enteric pathogenic Esc. coli were frequent. Concurrent infection by more than one parasite occurred in 18.6% of the infants. Most rotavirus infections (76.7%) occurred in infants under 12 months. Vomiting, severe dehydration and fever were frequent in children with rotavirus infection. At least one fecal marker of inflammatory diarrhea was registered in patients with bacterial infection. To our knowledge, this is first report of P. alcalifaciens associated with infantile diarrhea in Colombia and the first description of Esc. coli O157:H7 and Y. enterocolitica in our region.

Human infections due to Yersinia enterocolitica have been reported worldwide, predominantly in Europe. However, there have been few reports of Yersinia enterocolitica infection in Taiwan. We report a case of Y. enterocolitica sepsis in a 15-year-old Taiwanese girl with Cooley's anemia and insulin-dependent diabetes mellitus. She presented at admission with fever, shock and consciousness disturbance. She had symptoms of abdominal pain, vomiting and diarrhea for three days before admission. Blood pressure stabilized after intravenous normal saline rescue. Blood culture yielded Y. enterocolitica 2 days later and ceftriaxone was administered according to the results of sensitivity tests. She recovered well after a course of antibiotic treatment. Though Y. enterocolitica sepsis is rare in Taiwan, clinicians should be aware of its tendency to develop in patients with Cooley's anemia, fever and enterocolitis and that its clinical course may include sepsis leading to shock.
