title: Gastroduodenal disorders in children.
abstract: Studies within the past year examining the mechanisms underlying infantile hypertrophic stenosis at the cellular and molecular level are reviewed. A number of new modalities, including electrogastrography, and the 13C octanoid acid breath test have been used in the study of normal and abnormal gastrointestinal motility, as well as for the characterization of patterns of development of gastric motility in early infancy. Several studies pertaining to the natural outcome, the mode of transmission, and the associated symptomatology of Helicobacter pylori were published, attesting that, despite the tremendous progress achieved in our understanding of H. pylori, important gaps remain in our knowledge of this microorganism. Newly described clinical presentations of eosinophilic gastroenteritis and food allergy will also be of interest to the reader.
