Mitochondrial DNA (mtDNA)-depletion syndromes (MDS; OMIM 251880) are phenotypically heterogeneous, autosomal-recessive disorders characterized by tissue-specific reduction in mtDNA copy number. Affected individuals with the hepatocerebral form of MDS have early progressive liver failure and neurological abnormalities, hypoglycemia and increased lactate in(More)
BACKGROUND A window of opportunity has been suggested for reducing the risk of celiac disease by introducing gluten to infants at 4 to 6 months of age. METHODS We performed a multicenter, randomized, double-blind, placebo-controlled dietary-intervention study involving 944 children who were positive for HLA-DQ2 or HLA-DQ8 and had at least one first-degree(More)
OBJECTIVES Osteoporosis is the most common manifestation of untreated celiac disease (CD). Bone quantitative ultrasound (QUS) has recently emerged as a new modality for bone status assessment. We evaluated bone status in children with CD using dual-energy x-ray absorptiometry and quantitative ultrasound. METHODS This cross-sectional study included 41(More)
Non-Organic Feeding Disorders (NOFEDs) are frequently encountered in children younger than 6 years old. NOFED are characterized by feeding aversion, failure to advance to age-appropriate foods, food selectivity and negative mealtime behaviors. Parents of children with feeding disorders often use abnormal feeding behaviors, such as intrusive feeding.(More)
Mitochondrial respiratory chain disorders are an established cause of liver failure in early childhood. In some patients, the levels of mitochondrial DNA are markedly reduced, a condition referred to as mtDNA depletion syndrome (MDS). We report here on the ultrastructural changes in the livers of 10 infants with the hepatic form of this syndrome. All(More)
BACKGROUND Anti tumor necrosis factor alpha (TNFα) agents have become widely used in pediatric inflammatory bowel disease (IBD). So far, only few studies examined the long-term results of anti-TNFα treatment in children with IBD. METHODS The long-term outcome of pediatric patients with IBD was assessed retrospectively in a multicenter cohort of children(More)
OBJECTIVES Upper endoscopy (esophagogastroduodenoscopy [EGD]) has a limited role, if any, in the evaluation of functional abdominal pain (FAP). Nevertheless, children with intractable FAP are occasionally referred to EGD to rule out intestinal pathology. We evaluated the role of wireless video capsule endoscopy (VCE) in children referred for EGD with a(More)
Underweight and specific nutrient deficiencies are frequent in adult patients with inflammatory bowel disease (IBD). In addition, a significant number of children with IBD, especially Crohn's disease (CD) have impaired linear growth. Nutrition has an important role in the management of IBD. In adults with CD, enteral nutrition (EN) is effective in inducing(More)
BACKGROUND & AIMS Children with cerebral palsy (CP) have a high prevalence of pathologic fractures. Bone quantitative ultrasonography (QUS) has emerged as a radiation-free method for the assessment of bone quality and fracture risk. In this study, we applied QUS technique in order to investigate bone status in handicapped institutionalized children and(More)
BACKGROUND Pediatric-onset Crohn's disease (CD) is a heterogeneous disorder which is subjected to progression and complications in a substantial proportion of patients. AIMS We aimed to assess the progression in pediatric-onset CD phenotype on long term follow up. METHODS Medical charts of pediatric onset CD patients with at least 10 years follow-up(More)
