Ambient oxygen concentration and vascular endothelial growth factor (VEGF)-A are vital in lung development. Since hypoxia stimulates VEGF-A production and hyperoxia reduces it, we hypothesized that VEGF-A down-regulation by exposure of airways to hyperoxia may result in abnormal lung development. An established model of in vitro rat lung development was… (More)
BACKGROUND Previous work in our laboratory demonstrated that hyperoxia suppressed the expression of vascular endothelial growth factor (VEGF) by the embryonic lung, leading to increased epithelial cell apoptosis and failure of explant airway growth and branching that was rescued by the addition of Vegf165. The aims of this study were to determine protective… (More)
We report a 19-year-old man with pulmonary squamous cell carcinoma (SCC) who had a history of vertebral, anal, cardiac, tracheal, esophageal, renal, and radial limb defects (VACTERL) association and tracheoesophageal fistula (TEF) + esophageal atresia (EA) repair as an infant. Children that undergo TEF + EA repair may have an increased risk for developing… (More)
A term infant was born with respiratory distress, and subsequent imaging, histopathologic, and hormonal studies confirmed congenital hypothyroidism. This report is intended to alert pediatricians to the possibility of congenital hypothyroidism as a cause of respiratory symptoms of unknown cause in neonates with respiratory distress.
We report undescribed pulmonary findings in a child with mucolipidosis II (ML-II). Children with ML-II bear significant pulmonary morbidity that may include extensive pulmonary fibrosis, persistent hemosiderosis as well as pulmonary airway excrescences as they reach preschool age.
