Usefulness of Plasma Atrial Natriuretic Peptide Concentration in the Diagnosis of Patent Ductus Arteriosus in Preterm Infants
Byung Min Choi, Jae Kyun Yoon, Hyun Hee Lee, Hae Won Cheon, Kee Hwan Yoo, Young Sook Hong, Joo Won Lee, Soon Kyum Kim
Clin Exp Pediatr. 2000;43(7):897-904.   Published online July 15, 2000
Purpose : Diagnosis of a hemodynamically significant patent ductus arteriosus(PDA) that should be treated is difficult to determine by clinical and echocardiographic examinations. The aim of this study was to clarify the interrelationship of plasma atrial natriuretic peptide(ANP) concentrations and clinical signs or echocardiographic signs of PDA in preterm infants and use plasma ANP concentrations as a diagnostic indicator of a hemodynamically significant PDA. Methods...
Clinical Efficiency of Cardiac Troponin T for Myocardial Damage in Neonatal Asphyxia
Nam Soo Kang, Jae Kyun Yoon, Chang Sung Son, Joo Won Lee, Young Chang Tokgo, Sang Hee Kim
Clin Exp Pediatr. 1999;42(2):195-202.   Published online February 15, 1999
Purpose : The aim of this study was to evaluate the clinical efficiency of cardiac troponin T (cTnT) in detecting myocardial damage in neonatal asphyxia and to compare the diagnostic value of cTnT with creatine kinase MB(CK-MB). Methods : Sixty-three neonates were enrolled in this study, consisting of 27 asphyxiated infants (asphyxiated group; 1-min or 5-min Apgar score≤6) and 36 healthy...

A Case of Dexamethasone induced Hypertrophic Cardiomyopathy in Neonate with Bronchopulmonary Dysplasia
Youn Jung Choi, Soon Mi Jung, Jae Kyun Yoon, Ki Hyeng Lee, Chang Sung Son, Chang Tocko
Clin Exp Pediatr. 1998;41(5):711-715.   Published online May 15, 1998
Although hypertrophic cardiomyopathy is uncommon in infant and children, we have experienced a case of dexamethasone induced hypertrophic cardiomyopathy in preterm baby who had bronchopulmonary dysplasia. This patient had hyaline membrane disease. Therefore, he received prolonged mechanical ventilation that resulted in bronchopulmonary dysplasia. After we carried out dexamethasone therapy for 7 days, hypertrophic cardiomyopathy appeared in his echocardiographic finding. We...

Changes of Measles Specific IgG after Active Immunization of Measles in Korean Children
Young Kyoo Shin, Jae Kyun Yoon, Ji Tai Choung, Young Chang Tockgo
Clin Exp Pediatr. 1996;39(6):788-796.   Published online June 15, 1996
Purpose : Despite preventive measures, measles outbreaks ocurred in 1989, 1990 and 1994 in Korea. Especially, the proportion of immunized school aged children and adolescents was increased, and the reason was, in our opinion, primary and secondary vaccine failure after measles immunization. In this context, we attempted to evaluate the changes of measles specific IgG levels in various age groups of...
