title: A retrospective review of newborn screening for congenital hypothyroidism and newborn thyroid disease at a major medical center.
abstract: Objective. To study the frequency of congenital hypothyroidism (CH)/thyroid disorders at a major, urban medical center. Methods. We conducted a retrospective review of a preexisting database for 2007 to 2011. Infants were classified as having CH, secondary/tertiary hypothyroidism, thyroid-binding globulin deficiency, and other types of newborn thyroid dysfunctions. Results. A total of 353 (50%) abnormal newborn screens were found to be normal and 42% were abnormal on repeat. Of the latter, 14% had true CH, 1% had thyroid-binding globulin deficiency, and 27% had other causes of thyroid dysfunction. The 5-year incidence of CH at NYP Morgan Stanley Children's Hospital was significantly greater than in New York City, New York State, and Upstate New York. Conclusion. The incidence of CH and other thyroid dysfunctions were greater in our population for 2007 to 2010, after which there was an unexplained decline. The study underlines the importance of continued newborn screening for thyroid dysfunction.
