Feeding problems, anorexia and vomiting are common in infants and children with chronic renal failure (CRF), and play a major role in the growth failure often found in this condition. However, the gastroenterological and nutritional aspects of CRF in children have received little attention, hence therapeutic interventions are usually empirical and often(More)
BACKGROUND The purpose was to assess in Italy the clinical features at diagnosis of inflammatory bowel disease (IBD) in children. METHODS In 1996 an IBD register of disease onset was established on a national scale. RESULTS Up to the end of 2003, 1576 cases of pediatric IBD were recorded: 810 (52%) ulcerative colitis (UC), 635 (40%) Crohn's disease(More)
INTRODUCTION Eosinophilic esophagitis (EoE) is one of the most prevalent esophageal diseases and the leading cause of dysphagia and food impaction in children and young adults.

In children with chronic renal failure (CRF) anorexia, nausea, and vomiting are common yet poorly understood symptoms. We studied oesophageal and gastric motor function in 12 children (age 7 months-6.8 years) with severe CRF not undergoing dialysis who had persistent anorexia and vomiting. Eight of 12 patients had significant gastro-oesophageal reflux(More)
Objectives:In celiac disease (CD) the degree of histological damage in the duodenum may vary, but there is some controversy about the coexistence of villous atrophy and normal mucosa in different biopsy sites, i.e., patchy villous atrophy. We prospectively evaluated the degree, frequency, and distribution of histological lesions among different duodenal(More)
Chronic idiopathic intestinal pseudoobstruction is a serious disorder of intestinal neuromuscular function resulting in recurrent episodes of intestinal obstruction, and is caused by primary disease of the enteric nerves or enteric smooth muscle. Gastric electrical control activity detected by the non-invasive technique of surface electrogastrography was(More)
OBJECTIVES:It is generally believed that in gluten-sensitive enteropathy or celiac disease (CD), mucosal lesions may have a patchy distribution. We wanted to verify this concept and establish whether one or more biopsy samples are needed in order to make a correct diagnosis of CD.METHODS:One hundred and twelve consecutive children with positive(More)
