A small but significant subgroup of patients with irritable bowel syndrome (IBS) report a sudden onset of their IBS symptoms after a bout of gastroenteritis. Population-based surveys show that although a history of neurotic and psychologic disorders, pain-related diseases, and gastroenteritis are all risk factors for developing IBS, gastroenteritis is the most potent. More toxigenic organisms increase the risk 11-fold, as does an initial illness lasting more than 3 weeks. Hypochondriasis and adverse life events double the risk for postinfective (PI)-IBS and may account for the increased proportion of women who develop this syndrome. PI-IBS is associated with modest increases in mucosal T lymphocytes and serotonin-containing enteroendocrine cells. Animal models and some preliminary human data suggest this leads to excessive serotonin release from the mucosa. Both the histologic changes and symptoms in humans may last for many years with only 40% recovering over a 6-year follow-up. Celiac disease, microscopic colitis, lactose intolerance, early stage Crohn's disease, and bile salt malabsorption should be excluded, as should colon cancer in those over the age of 45 years or in those with a positive family history. Treatment with Loperamide, low-fiber diets, and bile salt- binding therapy may help some patients. Serotonin antagonists are logical treatments but have yet to be evaluated.

Acute gastroenteritis remains a common and often severe illness among infants and children throughout the world. The management of a child with acute diarrhea includes rehydration and maintenance fluids with oral rehydration solutions (ORS), combined with continued age-appropriate nutrition. However, although substantial data support the role of continued nutrition in improving gastrointestinal function and anthropometric, biochemical, and clinical outcomes, the practice of continued feeding during diarrheal episodes has been difficult to establish as accepted standard of care. Recommendations for maintenance dietary therapy depend on the age and diet history of the patient. It has been clear for many years that, when affected by gastroenteritis, breastfed infants should be continued on breast milk without any need for interruption and, by that way, will get faster recovery and improved nutrition. Moreover, many well-conducted studies have provided evidence that in formula-fed children not severely dehydrated, a rapid return to full feeding is well tolerated. Lactose intolerance and/or secondary cow's milk allergy are not a clinical concern for the vast majority of patients. In fact early refeeding i.e resumption of normal diet, in amounts sufficient to satisfy energy and nutrient requirements, should be the rule. However, in children younger than 6 months of age, the lack of suitable studies must lead to caution and use of specific lactose-free or extensively hydrolysate formulae, especially in case of severe and/or prolonged diarrhea. Several studies support the use of zinc supplementation or probiotics for acute diarrhea but some doubts persist in infant in developed countries.
