The prevalence of Aeromonas spp. and other enteric pathogens in stool specimens from diarrheic and non-diarrheic patients was studied over a 12 month period (January to December, 1986). Except for the absence of fever, all the clinical features in Aeromonas diarrhea were comparable to those associated with other diarrheagenic agents. These features included abdominal pain (30%), vomiting (24.5%), fever (31.5%), dehydration (9.5%) and hematochezia (19.5%). Aeromonas spp. were more frequently isolated from patients with gastroenteritis (2.5%) than from control patients (1.0%) (P less than 0.05). Isolates were recovered more often during the dry months (66.7%), than during the wet months (33.3%). Among the enteric pathogens isolated, Aeromonas spp. (2.5%) ranked next to Esch. coli (14.5%) and Shigella spp. (6.3%) in prevalence. Other bacterial isolates included Plesiomonas shigelloides (1.5%) Vibrio spp. (1.0%), Yersinia enterocolitica (1.0%) and Salmonella spp. (1.8%).

Behaviors of low income urban mothers and child caretakers in the treatment of childhood less than 5 year diarrhea were analysed from a surveillance study conducted between August 1988 and July 1989. Help seeking behaviors of mothers and caretakers for 412 episodes of child diarrhea were as follows: investigators 37.1%, drug stores 18.2%, wait and see or self treatment 17.0%, private clinics 12.6%, near by hospital 10.2%, and local health center 4.9%. Major treatment practices included ORT alone (54%) and ORT plus antibiotics and/or antidiarrheal drug (22%). Overall ORT usage was 76%. Twelve percent of diarrheal episodes no treatment was given to the children. Antimicrobials were believed to be essential in addition to ORT especially when diarrhea was associated with fever, vomiting and bloody stools. Thirty-six percent of invasive diarrhea cases (Shigella, Salmonella, Campylobacter) were treated with antibiotics. Only 18.2% of noninvasive diarrhea received antibiotics, most of this antibiotic use being in rotavirus diarrhea where vomiting and some fever are prominent. Availability of oral rehydration salts (ORS) and good experience with ORT were the key to the extensive use or ORT in this study. A surprisingly small number of mothers and child caretakers (4.9%) sought help from the local health center when their children had diarrhea.

During January through June 1988, oocysts of Cryptosporidium were identified in fecal samples of 83 (7.7%) of 1073 children who presented with acute gastroenteritis. Other intestinal pathogens were less common: Salmonella 4.2%, E. coli 1.9%, Shigella 2.6% and Campylobacter jejuni 5.0%. Cryptosporidiosis (C) was more common under the age of 5 years than over (8.4% vs 1.8%, respectively, p less than 0.01). In 6 (7.2%) children with C, another stool pathogen was found. Frequent signs of C were diarrhea (85.4%), vomiting (36.3%) and fever (32.7%). Although no anticryptosporidial treatment was given, most children recovered within 5-9 days, but 6 had to be hospitalized: 4 were dehydrated and 5 had electrolyte imbalance. Repeated examination showed persistence of oocysts in the stools for up to 19 days. We conclude that C is a significant cause of gastroenteritis in Israeli children under the age of 5 years which occasionally requires hospitalization. We therefore recommend routine examination for C in cases of acute gastroenteritis.

During a survey examining the causes of diarrhea in the East African country of Djibouti, 140 bacterial pathogens were recovered from 209 diarrheal and 100 control stools. The following pathogens were isolated at comparable frequencies from both diarrheal and control stools: enteroadherent Escherichia coli (EAEC) (10.6 versus 13%), enterotoxigenic E. coli (ETEC) (11 versus 10%), enteropathogenic E. coli (EPEC) (7.7 versus 12%), Salmonella spp. (2.9 versus 3%), and Campylobacter jejuni-C. coli (3.3 versus 5%). Surprisingly, the EAEC strains isolated did not correspond to well-recognized EPEC serogroups. No Yersinia spp., enteroinvasive E. coli, or enterohemorrhagic E. coli were isolated during the course of this study. Only the following two genera were recovered from diarrheal stools exclusively: Shigella spp. (7.7%) and Aeromonas hydrophila group organisms (3.3%). Shigella flexneri was the most common Shigella species isolated. Patients with Shigella species were of a higher average age than were controls (27 versus 13 years), while subjects with Campylobacter or Salmonella species belonged to younger age groups (2.6 and 1.6 years, respectively). Salmonella cases were more often in females. Shigella diarrhea was associated with fecal blood or mucus and leukocytes. ETEC was not associated with nausea or vomiting. Anorexia, weight loss, and fever were associated with the isolation of Salmonella and Aeromonas species. EAEC, ETEC, EPEC, and Shigella species were resistant to most drugs used for treating diarrhea in Africa, while the antibiotic most active against all bacteria tested was norfloxacin. We conclude that in Djibouti in 1989, Shigella and Aeromonas species must be considered as potential pathogens whenever they are isolated from diarrheal stools and that norfloxacin should be considered the drug of choice in adults for treating severe shigellosis and for diarrhea prophylaxis in travelers.

The aetiology of acute diarrhoea was investigated in 245 children less than 3 years old in a paediatric outpatient clinic in southern India. In 55% of the children organisms were found in the stools, and one quarter were infected with multiple organisms. Viruses, enteropathogenic E. coli, shigella and campylobacter species accounted for 75% of all isolates. Cholera and helminthiasis were rare, and no child had amoebiasis. Clinical findings were useful in the diagnosis of shigella and rotavirus infection only. Children with shigellosis had classical dysentery, and a greater number of stools; they were unlikely to be breast-fed, to be less than 6 months old, or to have watery stools. Rotavirus infections were characterized by vomiting. Only 20% of the 245 children had an infection which could be treated effectively with antimicrobials.

A major cause of morbidity and mortality among children in developing countries is acute diarrhoea and rotavirus, a reovirus-like agent, is found to be a leading causative agent. We report here the incidence of rotavirus infection among infants and young children with gastro-enteritis treated at the Children's Hospital in Dammam, Kingdom of Saudi Arabia. One hundred and fifty children, aged between 1 and 60 months, suffering from diarrhoeal illness, were selected as the study cohort; another 150 hospitalized children of the same age group, but not suffering from diarrhoea, served as controls. Sixty-two per cent of the study children complained of watery diarrhoea and 39% of vomiting; all had mild to moderate dehydration. Seventy-two per cent had fever and 30% associated respiratory illness. Worst affected were those 7-12 months old, among whom rotavirus was detected by ELISA techniques in 39.6%, compared with 7.5% of the control children of comparable age group. We could not detect any rotavirus from control children aged over 36 months, whereas approximately 15% of the study children in this age group yielded rotavirus from the stool. The second most common pathogen isolated was Shigella ssp. It was isolated from 18.7% of children under study as against 3% of the controls.

The influence of the Pre-existing malnutrition (PEM) on the severity of diarrhoea as well as the causative organisms was studied on 60 cases. The duration of diarrhoea was prolonged in cases with PEM. The stool purgative rate ranged from 4-15 times/day in PEM infant while it was 3-6 times in well nourished cases (WNC) (P less than 0.05). Also vomiting and dehydration was more marked among PEM cases (52.9% and 32.4% of cases than in WNC cases (31.3% and 12.5% of cases) (P less than 0.05). Rota virus and Candida albicans were the Commonest identified organisms in the stools of the PEM cases, they were detected in 52% and 38.2% of cases respectively while 25% of WNC had rota virus in their stool and non of them had Candida (P less than 0.02). Giardia lamblia was detected in 23.5% and 18.8% of PEM and WNC while 10% of healthy controls had Giardia. Other bacterial enteropathogen were also found less frequently including Salmonella, Shigella, E. coli, Pseudomonas and Campylobacter. There was no statistical difference in the incidence between both groups. Multiple infections were detected in 47% and 18.7% of PEM cases and WNC (P less than 0.05) and correlated with the severity of illness.

Acute diarrhea is a common problem in children. Understanding the different pathologic processes that cause diarrhea, and the agents that are associated with those processes, can aid the clinician in predicting the etiology of the diarrhea in an individual patient. Small bowel involvement, most commonly caused by Rotavirus, produces a high incidence of vomiting, often before the onset of diarrhea, and large, watery, and relatively infrequent stools. Large bowel involvement, usually due to Campylobacter, Salmonella, or Shigella produces frequent, often bloody stools containing leukocytes. Treatment of diarrhea should be focused on correcting dehydration, principally with oral rehydration solutions containing appropriate concentrations of electrolytes and carbohydrates. Early refeeding, avoiding foods containing lactose, should be considered for most pediatric patients with acute diarrhea. Antimicrobial therapy should be reserved primarily for parasitic infectious, pseudomembranous enterocolitis, and the early stages of a Campylobacter dysentery. The etiology of acute pediatric diarrhea can be predicted in most patients and early, appropriate treatment can be instituted.

Patients below 5 yr of age, hospitalised for shigellosis over a period of four years (1984-87), were studied. During the epidemic of bacillary dysentery (1984) isolation of different Shigella spp. as well as Shigella dysenteriae type 1 was high. Decreased isolation of Sh. dysenteriae type 1 and increased isolation of Sh. flexneri was observed during post-epidemic years (1985-87). Isolation of different Shigella spp. was always above 25 per cent from patients with dysentery and greater than 7 per cent from those with watery diarrhoea during the post-epidemic years. Higher incidence of shigellosis was observed amongst older children (greater than 3 yr). Most of the shigellosis patients complained of blood and mucus in stools. Vomiting was common among shigellosis patients presenting with watery diarrhoea whereas fever was commonly seen in patients with both dysentery and watery diarrhoea. Most patients of shigellosis presenting with blood and mucus in stools had no dehydration.

Guillain-Barre syndrome is known as one of the autoimmune disease, but the etiology, pathophysiology relating immune reaction, as well as the treatment are not established. It still causes physical handicap although its rate is low. The causes, clinical symptoms and outcome of 132 cases of Guillain-Barre syndrome have been analyzed. The patients' ages ranged from 4 months to 15 years. The antecedent events for 56.1% of the patients were known. These were upper respiratory tract infection, unexplained fever, vomiting, diarrhea, vaccination, measles, german measles, shigellosis, mumps, hepatitis, pertussis and surgery in order of frequency. The CSF protein level reached a maximum at 12.3 +/- 9.5 days. Steroids did not influence the outcome of this disease. More studies are necessary to conquer the disease.
