Autistic disorder is a pervasive developmental disorder manifested in the first 3 years of life by dysfunction in social interaction and communication. Many efforts have been made to explore the biologic basis of this disorder, but the etiology remains unknown. Recent publications describing upper gastrointestinal abnormalities and ileocolitis have focused(More)
Hydrogen and methane in human breath derive entirely from bacterial fermentation in the intestinal lumen. The sources of substrates utilized for these reactions have not been completely determined. Basal excretion of both gases occurs in the fasted state, while malabsorbed carbohydrate commonly results in increased hydrogen but not methane production. Using(More)
Pediatric feeding disorders are common: 25% of children are reported to present with some form of feeding disorder. This number increases to 80% in developmentally delayed children. Consequences of feeding disorders can be severe, including growth failure, susceptibility to chronic illness, and even death. Feeding disorders occur in children who are(More)
Acute diarrhoea is a serious cause of infant morbidity and mortality, and the development of preventive measures remains an important goal. Bifidobacteria (which constitute the predominant intestinal flora of breastfed infants), as well as other lactic-acid-producing organisms such as Streptococcus thermophilus, are thought to have a protective effect(More)
BACKGROUND & AIMS Treatment for gastroesophageal reflux may be ineffective in patients with an eosinophilic infiltration of the esophagus. The aim of this study was to investigate whether unremitting symptoms of gastroesophageal reflux and biopsy abnormalities of the esophagus may be associated with the ingestion of certain foods. METHODS Ten children(More)
Autism is a collection of behavioral symptoms characterized by dysfunction in social interaction and communication in affected children. It is typically associated with restrictive, repetitive, and stereotypic behavior and manifests within the first 3 years of life. The cause of this disorder is not known. Over the past decade, a significant upswing in(More)
Three substrates labeled with nonradioactive 13C have been employed to establish a trilogy of noninvasive breath tests to detect fat malabsorption in children and then to differentiate the etiology of the steatorrhea. Administration of 17 mg/kg of (13C)triolein Lipomul (The Upjohn Co., Kalamazoo, Mich.) resulted in a peak excretion rate of 13CO2 greater(More)
The accuracy of the serum ceruloplasmin level in distinguishing chronic active hepatitis from Wilson disease was compared to the 24-hour urinary copper excretion and hepatic copper content in 20 untreated patients with chronic active hepatitis and 25 with Wilson disease. Serum ceruloplasmin levels were decreased in five patients (25%) with chronic active(More)
OBJECTIVE Macroamylasemia is considered to be rarely associated with celiac disease (CD). We have evaluated patients in whom macroamylasemia or elevated total amylase (TA) led to the diagnosis of CD. These cases served as a catalyst for examining the prevalence of elevated TA and macroamylase (MA) in patients with active CD. METHOD Total amylase and MA(More)
