Department of Paediatrics and Child Health

Despite nutrition interventions, stunting thought to be secondary to underlying environmental enteropathy (EE) remains pervasive among infants residing in resource-poor countries and remains poorly characterized. From a birth cohort of 380 children, 65 malnourished infants received 12 weeks of nutritional supplementation with ready-to-use therapeutic food (RUTF). Eleven children with insufficient response to RUTF underwent upper endoscopy with duodenal biopsies, which were compared with U.S., age-matched specimens for healthy, celiac disease, non-celiac villous atrophy, non-celiac intraepithelial lymphocytosis, and graft-versus-host disease patients. Of the 11 children biopsied, EE was found in 10 (91%) with one subject with celiac disease. Morphometry demonstrated decreased …

Rates Of Developmental And Behavioral Screening Of Young Children: Implications For Health Care Policy And Practice, Shirley Berger

Dissertations and Theses

Background: The skills and capacities developed during early childhood are the foundation for a child’s future academic functioning, economic productivity, and lifelong health and mental health. When young children have developmental delays or disabilities, early identification and intervention lead to better outcomes; however, only a minority are identified before school entry. Primary care is an important setting for identification of developmental and behavioral conditions as most young children attend well-child visits regularly and parents expect developmental guidance from pediatricians. Two key pediatric preventive services are recommended: developmental monitoring/surveillance at every well-child visit and developmental screening at 9 months, 18 months, …
