Oligohydramnios affects pulmonary functional/structural abnormalities in school-aged children with bronchopulmonary dysplasia
Jeong Eun Shin, Soon Min Lee, Mi-Jung Lee, Jungho Han, Joohee Lim, Haerin Jang, Ho Seon Eun, Min Soo Park, Soo Yeon Kim, Myung Hyun Sohn, Ji Ye Jung, Kyung Won Kim
Clin Exp Pediatr. 2024;67(5):257-266.   Published online April 16, 2024
Question: Is bronchopulmonary dysplasia (BPD) associated with functional/structural abnormalities later in life?
Finding: School-aged children with severe BPD had abnormalities on pulmonary function tests and lung computed tomography despite no subjective respiratory symptoms; however, only prenatal oligohydramnios and prolonged ventilator use were associated with abnormal lung function.
Meaning: Long-term monitoring of preterm infants’ lung health is essential, especially for those with prenatal oligohydramnios or prolonged ventilator use.

Soon Min Lee, Min Soo Park, Kook In Park, Ran Namgung, Chul Lee, Jin Seong Lee, Kyung A Lee, Jong-Rak Choi
Clin Exp Pediatr. 2009;52(5):603-606.   Published online May 15, 2009
The Pierre Robin sequence (PRS) is the nonrandom association of micrognathia, cleft palate, and glossoptosis, leading to respiratory and feeding difficulties that appear neurogenic rather than mechanical in causation. Genetic determinants are thought to underlie this functional and morphological entity, based on the existence of Mendelian syndromes with PRS. Here, we demonstrate the association of PRS with trisomy 8p due...
