Case Report
Successful pleurodesis with OK-432 in preterm infants with persistent pleural effusion
Jeong Eun Kim, Chul Lee, Kook In Park, Min Soo Park, Ran Namgung, In Kyu Park
Clin Exp Pediatr. 2012;55(5):177-180.   Published online May 21, 2012

OK-432 (picibanil) is an inactivated preparation of Streptococcus pyogenes that causes pleurodesis by inducing a strong inflammatory response. Intrapleural instillation of OK-432 has recently been used to successfully treat neonatal and fetal chylothorax. Here we report a trial of intrapleural instillation of OK-432 in two preterm infants who were born with hydrops fetalis and massive bilateral pleural effusion. Both cases...

Case Report
De novo interstitial direct duplication 8 (p21.3p23.1) with Pierre Robin sequence
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...
