Hyun Joo Lee, Eun Ae Park, Seung Joo Lee, Mi Jeong Kim, Soon Hee Seong
Clin Exp Pediatr. 1996;39(12):1759-1762.   Published online December 15, 1996
Tracheal agenesis is the rare and uniformly lethal anomaly that presents with severe respiratory distress and aphonia after birth. In this anomaly, the trachea is usually absent and air is reaching the bronchi through a communication with the esophagus. The diagnosis should be suspected in a nowborn infant with respiratory distress whose intubation is difficult. We report an autopy case of tracheal...

It has been known that intrauterine thyroid hormone deficiency may be one of the factors predis- posing to RDS in premature infants. L-thyroxine has been shown to increase the production opf lung surfactant, widely accepted as deficient in RDS infants, as association between lung immaturity and fetal thyroid function is postulated. The authors investigated thyroid hormone concentration at birth and 5, 15 days of...

Clin Exp Pediatr. 1989;32(10):1402-1407.   Published online October 31, 1989
Insulin seems to exert an inhibitory effect on lung maturation. The incidence of respiratory distress syndrome in neonates of diabetic mothers is significantly greater than that observed in age-and weight-matched controls. Thus hyperinsulinemia may be an important factor in the developemnt of RDS. We investigated the relationship between cord blood insulin concentration and subsequent develop- ment of RDS in 32 premature neonates born at Koryo...
