The thirty eight newborn infants with periventricular leukomalacia who were admitted to the neonatal intensive care unit of Gil General Hospital from March 1, 1988 to June 30, 1991, were investigated for ultrasonographic findings, risk factors and neurological outcome. The results were as follows: 1) There were 38 cases of PVL including 21 echogenic flarings and 17 cystic PVL's. 2) Mean birth weight was 2,250 gm and mean gestational age was 35 week. 3) Mean detection timing was 4th day in echogenic flarings and 18th day in cystic PVL's. 4) PVL's were located in the parietal region in 1 case and fronto-parieto-occipital in 3 cases. 5) Mean cyst size was 6 mm. 6) Multiple logistic regression analysis for the risk factors of PVL showed that low birth weight, apnea and seizure were the most significant contributing factors (p<0.05). 7) In the follow-up study of cystic PVL's, 7 cases showed improvement, 7 cases developed into multicystic encephalomalacia and 3 cases developed into atrophy. 8) Neurodevelopmental outcome of cystic PVL's showed nomal; 6.2%, minor neurodevelopmental defect; 43.8%, major neurodevelopmental defect; 31.2% and death; 18.8%. 9) Neurosonographic predictability for neurodevelopemental sequelae by cystic PVL's showed sensitivity; 63.6%%, specificity; 98.0%, positive predictive value; 92.8% and accuracy; 88.2%. 10) Major neurodevelopmental defect was more frequent, cyst size being larger and location being more extensive (p<0.05).

4.The Normal Values of Pulmonary Function Test (PFT) in Neonates according to Postconceptional Age (PCA) and Changes of PFT in Neonatal Respiratory Diseases.
Journal of the Korean Society of Neonatology 2006;13(1):24-31
PURPOSE: Aim of this study is to obtain the normal values of pulmonary function test (PFT) in newborn babies according to their postconceptional age and to detect changes in PFT values of neonatal lung diseases including respiratory distress syndrome and meconium aspiration pneumonia. METHODS: PFT was performed in 60 newborn babies who were admitted in the neonatal intensive care unit and newborn nurseries of Inje University Sanggye Paik Hospital from 2002. 11. 1. to 2003. 10. 31. The PFT data of 20 respiratory distress syndrome (RDS) and 20 meconium aspiration pneumonia patients during the same period were analyzed and compared with normal values of similar postconceptional age group to find what kind of changes in PFT values occur in patient groups. PFT values including compliance (C), resistance (R), functional residual capacity (FRC), tidal volume (TV), percent volume to peak flow (%V-PF) were measured. RESULTS: 1) In PCA 30-32 week newborns, C:1.22+/-0.43 (mL/cmH2O), R:0.12+/-0.07 (cmH2O/mL/sec), FRC:20.9+/-12.7 (mL/kg), TV:7.1+/-3.6 (mL/kg), In PCA 33-36 week newborns, C:1.81+/-0.76 (mL/cmH2O), R:0.09+/-0.04 (cmH2O/mL/sec), FRC:23.3+/-14.1 (mL/ kg), TV:7.3+/-4.3 (mL/kg). In PCA 37-42 week newborns, C:2.08+/-0.57 (mL/cmH2O), R:0.08+/-0.06 (cmH2O/mL/sec), 28.3+/-13.4 (mL/kg), TV:8.5+/-4.1 (mL/kg). 2) In RDS patients of PCA 30-36 week, C:0.08+/-0.02 (mL/cmH2O), FRC:12.3+/-4.3 (mL/kg), %V-PF:0.27+/-0.11. These values were significantly decreased comparing with normal PFT values of newborns with similar postconceptional age (P<0.05). CONCLUSIONS: Lung compliance and FRC of normal newborns increased with increase of their postconceptional age. In RDS patients compliance, FRC and %V-PF were significantly decreased comparing with normal newborns with similar postconceptional age.

PURPOSE: The aim of the study was to determine the incidence of cystic periventricular leukomalacia (PVL) and identify the risk factors for cystic PVL in preterm infants with gestational age (GA) less than 32 weeks according to gestational age group. METHODS: The medical records and brain imaging were reviewed for preterm infants with less than 32 weeks GA who lived more than 4 weeks and admitted to the neonatal intensive care unit at Inje University Sanggye Paik Hospital from January 2009 to June 2015. We determined the incidence and the risk factors for the development of cystic PVL in preterm infants according to GA group. RESULTS: Incidence of cystic PVL was 15.1% (26/172). Multivariate analysis showed that intraventricular hemorrhage (IVH) [P=0.006, odds ratio (OR) 5.478, 95% confidence interval (CI) 1.641-18.285), oxygen uses over 28 days (P=0.025, OR 3.086, 95% CI 1.152-8.264), and NEC (P=0.042, OR 3.731, 95% CI 1.047-13.333) were independent risk factors for the developmental of cystic PVL. Subgroup analysis showed that pregnancy-induce hypertension and IVH were independent risk factors in preterm infants with GA of less than 28 weeks. Also, oxygen uses over 28 days and culture proven sepsis were independent risk factors in preterm infants with GA of 28(+0)-31(+6) weeks. CONCLUSION: These results suggest that pregnancy-induce hypertension and IVH may increase the risk for the subsequent development of cystic PVL in preterm infants with GA of less than 28 weeks, and oxygen uses over 28 days and culture proven sepsis may increase in preterm infants with GA of 28(+0)-31(+6) weeks.

Neonatal hyperbilirubinemia is a significant risk factor for the developemtn of otoneurologic disorder. Hyperbilirubinemia resulting in kernicterus produces widespread neuronal damage with the most common sites of staining and destruction involving the hippocampus, basal ganglia and the brainstem nuclei in the floor of the fourth ventricle, including the dorsal cochlear nucleus. ABR may be a useful tool for the monitoring early bilirubin toxicity and postcteric sequelae in infants. This study attempts to evaluate the clinical neurodevelopmental outcome in hyperbilirubnemic infants requiring exchange transfusion through the assessment of ABR. Eight hyperbilirubinemic neonates with severely abnormal ABR findings and twelve hyperbilirubinemic neonates with normal ABR findings were studied to assess their neurodevelopemental outcome. The results were as follows; 1) There were 8 severely abnormal ABR cases, including 5 cases of bilateral flat wave and 3 cases of unilateraly elevated hearing throeshold. 2) The major cause of hyperbilirubinemia was ABO incompatibility(65%) 3) Significant clinical finding associated with severely abnormal ABR was kernicterus(p<0.05) 4) Significant laboratory findings associated with severely abnormal ABR were lower levels of hemoglobin and hematocrit(p<0.05) 5) 2 cases of bilateraly flat ABR and 3 cases of unilaterally elevated hearing threshold could be classified into sensorineural type hearing defect by latency-intensity function curve. 6) At the follow up tests of 3 cases of bilaterally flat ABR, 2 cases showed no change and 1 case showed mild improvement. 7) Among 5 follow up cases of severely abnormal BR, only 1 case showed normal neurodevelopmental outcome, 3 cases showed major neurodevelopmental defect and 1 case showed minor neurodeveoplemental defect. Among them, 1 case has had definite hearing disability.
