Premature constriction of the ductus arteriosus is rare, but it can occur during fetal life idiopathically or secondary to medications or structural lesions. Premature constriction of the ductus arteriosus can lead to progressive right heart dysfunction, heart failure, subsequent hydrops fetalis, and even fetal death. Herein, we describe a case of fetal ductus arteriosus constriction of unknown etiology with a severely enlarged and hypertrophied right ventricle, which resolved dramatically soon after birth.

Monochorionic twins with discordant karyotypes are rare and mostly caused by post-zygotic mitotic nondisjunction. A 32 year old nulliparous woman at 11 weeks of gestation with spontaneous twin pregnancy was referred to our hospital. An amniocentesis was performed in both amniotic sacs at 15 weeks of pregnancy. One fetus in monochorionic twin pregnancy was diagnosed with Turner syndrome with cystic hygroma, and the other fetus was normal. Because of high mortality rate in abnormal fetuses, the umbilical cord coagulation was performed using radiofrequency ablation to prevent the damage of co-twin that may be caused by the demise of one fetus. After delivery, chorionicity of placenta was ascertained by pathologic exam. Postnatal findings of physical exam, abdominal and brain sonography were normal in the surviving neonate.

PURPOSE: Perinatal asphyxia is a major factor correlated with diseases that cause respiratory distress in a neonate. So we aimed to investigate the relationship between respiratory distress syndrome (RDS) and transient tachypnea of newborn (TTN) with plasma biological markers of perinatal asphyxia in full-term neonates. METHODS: Full-term neonates with transient tachypnea of the newborn (TTN) and respiratory distress syndrome (RDS) who were admitted within 24 hours after birth were enrolled in a study group. And control group are infants with premature rupture of amniotic membrane without significant findings. Serum lactate dehydrogenase (LDH), aspartate transaminase (AST), alanine transaminase (ALT), creatine kinase (CK) and myoglobin were measured at admission. RESULTS: Of the total 80 infants, 54 were of the study group and 26 were of the control group. The numbers of RDS and TTN groups were 27 and 27, and the numbers of RDS with hypoxic-ischemic encephalopathy (HIE) and RDS without HIE were 6 and 21 retrospectively. Serum AST, ALT, LDH and CK were significantly higher in the study group than the control group (P<0.05). When RDS group and TTN group were compared AST and LDH were significantly higher in RDS group than TTN group (P<0.05). Serum AST, ALT and LDH were significantly higher in RDS with HIE group than RDS without HIE group (P<0.05). A prediction of RDS by LDH analysis showed good correlation by receiver operating characteristic curve (P<0.05). A cut off level of 720 IU/L for LDH was the best predictor of RDS (sensitivity 63% and specificity 86%). CONCLUSION: LDH is an excellent predictor to differentiate RDS from TTN soon after birth in full-term neonates with respiratory distress.

PURPOSE: This study aimed to compare the neonatal outcome by quantifying the effect of maternal age on low birth weight (LBW). METHODS: We reviewed the medical records of 12,742 newborn infants born at CHA Bundang Medical Center from January 2009 to December 2013. Infants were compared after being categorized by the following 4 maternal age groups - <25 years (N=343), 25-34 years (N=8,573), 35-39 years (N=3,186), > or =40 years (N=640). Statistical analysis included use of logistic regression models with likelihood ratio tests for interaction effects. RESULTS: Incidence of perinatal complications tended to increase significantly with maternal age - gestational diabetes mellitus (GDM; P<0.001), pregnancy induced hypertension (PIH; P=0.019), placenta previa (P<0.001), and cesarean section (P<0.001). Compared to the age group of 25-34 years (reference group), no significant differences were found in age group of 35-39 year [odds ratio (OR)=0.945, 95% confidence interval (CI) 0.847-1.056, P=0.319] and > or =40 years (OR=0.841, 95% CI 0.671-1.056, P=0.136) for LBW. After adjusted by gestational age, incidence of in vitro fertilization (IVF), and perinatal complications, maternal age was not found to be an independent risk factor for LBW (OR=0.847, 95% CI 0.730-0.982, P=0.028 for 35-39 years, and OR=0.652, 95% CI 0.481-0.884, P=0.006 for > or =40 years). CONCLUSION: Although incidence of perinatal complications tends to increase with age, neonatal outcome of age group of > or =35 years measured by incidence of LBW infants was not unfavorable compared to the reference group. The result suggests that the thorough prenatal care may be more important than the maternal age itself.

PURPOSE: The purpose of this study is to investigate the perinatal risk factors for severity of intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWIs) and to study the following neurodevelopmental outcomes depending on the degree of IVH severity. METHODS: The retrospective study included 145 VLBWIs who were admitted at Seoul St. Mary's Hospital between May of 2009 and April of 2013. Prenatal, obstetric and postnatal risk factors for IVH were investigated. VLBWIs were divided into the group of IVH grade 1-2 and IVH grade 3-4. During this study period, 26 VLBWIs were died and 11 VLBWIs were lost to followed up, thereby 108 infants were included in the final analysis. They were regularly followed up and assessed for presence of major neurodevelopmental impairments including cognitive impairment, cerebral palsy, visual deficit, hearing deficit, and epilepsy. Among 108 infants, 23 (21.3%) patients had neurodevelopmental impairments. RESULTS: The lower gestational age and birth weight were significant prenatal risk factors for severe IVH. Lower Apgar score at 1 and 5 min, hypotension/shock, higher levels of partial pressure of carbon dioxide, presence of patent ductus arteriosus, pneumothorax, thrombocytopenia, necrotizing enterocolitis, and bronchopulmonary dysplasia were significant postnatal risk factors for severe IVH. After multiple logistic regression analysis, gestational age, birth weight, and hypotension/shock were independent risk factors for severe IVH. The incidence of major neurodevelopmental impairments were also significantly higher in VLBWIs who survived after severe IVH. CONCLUSION: In addition to preterm birth, minimizing hypotension/shock, the risk factor of severe IVH, is important to prevent major neurodevelopmental impairments in VLBWIs.

PURPOSE: In this study, the risk factors of failure of ibuprofen treatment in preterm infants with hemodynamically significant patent ductus arteriosus (hsPDA) were investigated. METHODS: Among 403 preterm infants (<32 weeks gestation) born between January 2010 and December 2012, 125 infants treated with ibuprofen for hsPDA were retrospectively reviewed. The preterm infants were divided into the following groups according to their response to the 1st and 2nd cycles of ibuprofen treatment: responder groups I and II, closure of the ductus arteriosus after the 1st and 2nd cycles of ibuprofen treatment; and non-responder groups I and II, persistency of hsPDA after the 1st and 2nd cycles of ibuprofen treatment. RESULTS: One hundred twenty five infants were enrolled in the study: 74 in responder group I, 51 in non-responder group I, 14 in responder group II, and 22 in non-responder group II. In non-responder group I, the gestational age and birth weight were smaller, the postnatal steroid treatment was more frequent, and the duration of mechanical ventilation and the days spent in the hospital were prolonged.I n non-responder group II, the gestational age and birth weight were smaller, the diameters of the ductus arteriosus were larger, and the inotropics use was more frequent. CONCLUSION: Failure of ibuprofen treatment of hsPDA is associated with the diameter of the ductus arteriosus and with inotropics use. Obtaining data regarding these is expected to help in determining if early direct surgical ligation is needed.

PURPOSE: We evaluated the clinical characteristics of term infants admitted to the neonatal intensive care unit (NICU) from nursery. METHODS: This is a study of NICU-admitted infants who were born > or =37 weeks of gestation at the Bungdang CHA Hospital between January 2012 and August 2013 (n=161). The infants were divided into 3 groups. The "nursery room (NR) group" (n=97) comprised admissions from the nursery following a late deterioration in condition. The "delivery room (DR) group" (n=64) comprised infants who required admission to the NICU immediately after delivery. In addition, healthy term infants who were selected as the "Term group" (n=95). RESULTS: The NR group had a higher incidence of respiratory distress syndrome than DR group (28.9% vs. 14.1%, P=0.029). Compared with the Term group, the NR group had increased incidence of prolonged (>18 h) premature rupture of membranes (PROM) (6.2% vs. 0.0%, P=0.029). By logistic regression analysis, comparing NR group and Term group, a 1 min Apgar score < or =7 points {odds ratio (OR) and 95% confidence intervals (CI) 3.1 (1.0-9.1)}, a requirement of O2 at birth 2.6 (1.2-5.9) and abnormalities detected on an antenatal sonogram 3.3 (1.4-7.8) were associated with an increased risk of admission to NICU. CONCLUSION: Risk factors for NICU admission from nursery in term infants included prolonged PROM, a 1 min Apgar score of < or =7 points, a requirement of O2 at birth, and abnormalities on antenatal sonograms. Term infants with these risk factors should be carefully observed in the early neonatal period.

Antibiotics are among the most commonly prescribed medicines during pregnancies for various reasons. The antepartum use of antibiotics requires the consideration of maternal physiologic change, its effects to fetuses and drug-resistance. Usually, antibiotics are prescribed to pregnant women complicated with preterm labor, preterm premature ruptures of the membranes, urinary tract infection or sexually transmitted diseases. In this article, we reviewed the antepartum use of antibiotics in obstetrical management.

Parenting needs to be approached by cultural and economic aspects. Our society has become disordered because of the conflicts of multicultural values caused by dramatically developing economy. Between generations there are differences of ideas of many things, which are marriage, diet, daily living, and even relationships with the others. In old days, children were used to learn these values through their extended family. It did not need to be said or shared, but acquired just naturally. We, however, live in a society in which concept of parenting is rapidly changing almost every five years. There is no such a thing called a success or a failure. It can differ based on the perspective we try to look at. There is also difference in peoples' goal. Parenting has a meaning of raising myself, which means that parents become true parents by raising their offspring. Children can be the happiest when they grow surrounded by family and can have strong ties to their parents. There is tremendous amount of stress during perinatal period to both mother and her child. Therefore, closely monitoring mother's anxiety about infant care is the most important step to build proper bonds between a mother and a child. Affection is a crucial mental connection, which makes possible for children to live and also be able to help others. Stable bonds can be foundations of becoming positive and active person and it will affect the child's life entirely. It will be better to teach them how to listen to the others rather than focusing on them too much. Children need to learn how to solve their problems and build their own future. Thus, what parents should do is taking a step back, giving them a time, and waiting for their children to grow up. I believe this is the ultimate parenting purely from love.

Ovarian tumor in pregnancy is not rare and benign cystic teratoma is most common ovarian tumor in pregnancy. Most ovarian tumor in pregnancy is found at first and second trimester but sometimes found at third trimester and it is difficult to make a decision for management. Moreover physician should consider fetal age and mother's condition, and weigh outcome of operation for complicated ovarian tumor in pregnancy. Torsion of ovarian tumor is not an uncommon complication during first trimester of pregnancy and puerperium but rare occurs during the third trimester of pregnancy. We have experienced a case of torsion of benign cystic teratoma of ovary which occurred at 37 weeks gestation in a 25 year-old woman. So we report this case with a brief review of literature.
