A 2-day-old male (Premie, Large for gestational age(LGA), Intrauterine period(IUP) 33 weeks, birth weight 2,955 gram) was transferred with marked abdominal distention, bilious return via the orogastric tube, respiratory difficulty, and generalized edema (hydrops fetalis). He was born by cesarean section to a 36 year-old mother. Antenatal ultrasonogram at IUP 31 weeks demonstrated multiple dilated bowel loops suggestive of intestinal obstruction. There was no family history of cystic fibrosis. Simple abdominal films disclosed diffuse haziness and suspicious fine calcifications in the right lower quadrant. Barium enema demonstrated a microcolon. Sweat chloride test was not available in our institution. At laparotomy, there noted 1) a segmental volvulus of the small bowel with gangrenous change, associated with meconium peritonitis, 2) an atresia of the ileum at the base of the volvulus, and 3) the terminal ileum distal to the volvulus was narrow and impacted with rabbit pellets-like thick meconium. These findings appeared to be very similar to those of a complicated meconium ileus. In summary, the ileal atresia and meconium peritonitis seemed to be caused by antenatal segmental volvulus of the small intestine in a patient with probable meconeum ileus.
Purpose : It was generally accepted now a days that the pathogenesis of preeclampsia, small for gestational age (SGA), intrauterine growth retardation and fetal origin of adult diseases were related with a endothelial cell dysfunction. The purpose of this study was to know the relation of such diseases by assessing the level of endothelin-1. Methods : SGA babies, newborns of preeclampsia and normal control mother were included in this study. Isolated endothelial cells were centrifugated and mixed with media in $37^{\circ}C$, 5% $CO_2$ to obtain confluent monolayer of cultured human umbilical venous endothelial cell (HUVEC). Endothelin-1 levels were determined by Endothelin-1 colorimetric (EIA) Kits. We examined the endothelin-1 level in the HUVEC supernatants from SGA baby, and newborns from preeclampsia as well as normal mother. Also, we compared the endothelin-1 level of cultured normal HUVEC incubated with serum from cord blood of SGA, babies of preeclampsia or normal control mother. Results : The endothelin-1 levels in cultured HUVEC supernatants of three groups showed no significant difference but the endothelin-1 levels of cultured normal HUVEC incubated with serum from preeclampsia mother or SGA mother was significantly higher than those from newborns of control mothers (P<0.05). Conclusion : These findings suggest that there may be the factor which affect the endothelin-1 level in serum of cord blood from SGA and preeclampsia.

Purpose : Being small for gestational age (SGA) is a risk factor of short stature in children. Genetic background such as mid-parental height (MPH) is known to influence growth of children born SGA. We studied the relationship between growth of children born SGA and MPH and studied the effects of insulin-like growth factor (IGF-I) and insulin-like growth factor binding protein 3 (IGFBP-3) on postnatal growth in children born SGA according to MPH. Methods : Forty-nine neonates born SGA were included in this study. We defined corrected height standard deviation score (cHtSDS) by modified height SDS (HtSDS) based on their MPH. We categorized subjects into group 1 consisting of children with cHtSDS ${\geq}0$ (n=35) and group 2 consisting of children with cHtSDS <0 (n=14), and compared IGF-I and IGFBP-3 between the two groups. Results : The HtSDSs and cHtSDSs in groups 1 and 2 were $0.06{\pm}1.05$ vs. $-0.95{\pm}0.85$ (P=0.000) and $0.78{\pm}0.93$ vs. $-0.46{\pm}0.67$ (P=0.000), respectively. IGF-I SDS was higher in group 1 than in group 2 ($2.82{\pm}3.69$ vs. $0.23{\pm}2.42$, P=0.012). Total cHtSDS ($0.42{\pm}1.03$) was significantly higher than HtSDS ($-0.22{\pm}1.10$) (P=0.000). Conclusion : Our results show that cHtSDS differs significantly from HtSDS. Growth assessment by standardized growth curve does not uniformly show effects of genetic factors. A more accurate assessment of growth uses a personalized corrected growth curve that considers the genetic factor measured by MPH.
Purpose : Extrauterine growth restriction (EUGR) in preterm infants is a major problem in neonatal intensive care units (NICUs) and it has been related to long-term growth deficit and neurodevelopmental issues. The aim of this study was to investigate the frequency of and risk factors for EUGR. Methods : The study subjects consisted of very low birth weight (VLBW) infants with a gestational age $\leq$32 weeks that were born at the Seoul National University Children's Hospital between November 2005 and April 2009. EUGR was defined as weight for gestation, lower than the 10th percentile on discharge. Results : The frequency of EUGR was 67% (n=111/166). By multiple logistic regression, the presence of small for gestational age (SGA) was the greatest predictor of EUGR, birth weight and daily weight gain during the first 28 days were independent predictors of EUGR. Risk factors for EUGR in non-SGA infants were evaluated because 56% (64/114) of non-SGA infants developed EUGR at discharge. Daily weight gain in the first 28 days was also decreased in EUGR group and independently predicted the risk of EUGR in the non-SGA group. Conclusion : EUGR was a common problem in the NICU. SGA was the most significant predictive factor of the EUGR. Half of the non-SGA infants also developed EUGR, revealing poor weight gain in the early days was as an important predictor. These results support the importance of early nutritional intervention for weight gain which have lagged behind other modern therapeutic interventions when the infant is clinically unstable.
Objective: To investigate adverse pregnancy outcomes in non-obese women with polycystic ovary syndrome (PCOS) compared with obese-PCOS and control groups. Methods: Women with PCOS who underwent assisted reproductive technology (ART) from August, 2003 to December, 2007, were considered. A total of 336 women with PCOS were included in the study group and 1,003 infertile women who had tubal factor as an indication for ART were collected as controls. They were divided into four groups: a non-obese PCOS group, obese-PCOS group, non-obese tubal factor group, and obese tubal factor group, with obesity defined by a body mass index over 25 kg/$m^2$, and reviewed focusing on the basal characteristics, ART outcomes, and adverse pregnancy outcomes. Results: There was no difference among the groups' the clinical pregnancy rate or live birth rate. Regarding adverse pregnancy outcomes, the miscarriage rate, multiple pregnancy rate, and prevalence of preterm delivery and pregnancy induced hypertension were not different among the four groups. The incidence of small for gestational age infant was higher in the PCOS groups than the tubal factor groups ($p$ <0.02). On the other hand, the morbidity of gestational diabetes mellitus (GDM) was not high in the non-obese PCOS group but was in the obese groups. And in the obese PCOS group, the newborns were heavier than in the other groups ($p$ <0.02). Conclusion: Non-obese PCOS presents many differences compared with obese PCOS, not only in the IVF-parameters but also in the morbidity of adverse pregnancy outcomes, especially in GDM and fetal macrosomia.
Purpose: To evaluate the impact of delayed interval delivery on neonatal outcomes. Methods: This was a retrospective study of infants who were born at Seoul National University Hospital by delayed interval delivery from June 2005 to July 2010. Outcomes (neonatal mortality and morbidity) of later babies were compared to those of the first babies and the control group whose gestational ages and birth weights were similar to them. Results: There were 4 twin and 5 triplet pregnancies. The first babies (group 1, n=9) were delivered at $22^{+6}$ to $27^{+5}$ weeks of gestational age, and the later babies (group 2, n=14) were born at $24^{+6}$ to $28^{+0}$ weeks. The mean interval between the first and later deliveries was 10 days, and there was no delay between the second and third deliveries in all triplet pregnancies. There were more small for gestational age (SGA) infants in group 1 than group 2 (66.7% and 21.4% respectively, P=0.03). Two of three babies who died in group 1 were born before 24 weeks of gestational age and expired within a week after birth. The mortality rate of group 2 (7.1%) was lower than group 1 (33.3%), but not significantly (P=0.106). The control group matched to group 2 consisted of 28 infants. There were no significant differences in neonatal mortality and morbidity between the two groups. Conclusion: Although there is a limitation to the number of infants in this study, it suggested that delayed delivery in a multiple pregnancy could decrease the incidence of SGA of the remaining fetuses and that prolonged gestation would not be harmful to those fetuses after birth.
Purpose: Cytogenetic analysis of spontaneous abortions (SABs) provides valuable information to establish the causes of fetal loss, information that is essential to provide accurate reproductive and genetic counseling couples. Such analysis also provides information on the frequencies and types of chromosomal abnormalities and associated risks of recurrence. However, there have only been a few reports of chromosomal abnormalities in small samples of SABs in the Korean population. Here, we report the incidence and spectrum of chromosomal abnormalities for cases of 470 SAB in Korea. Material and Methods: Between 2005 and 2010, a total of 470 products of conception (POC) resulting from SABs were submitted to our laboratory for cytogenetic analysis from various medical sites in Korea. The incidences and types of specific chromosomal abnormalities were determined. The abnormalities were distinguished by gestational age at the time of SAB and by maternal age. Results: The frequency of chromosomal abnormalities in POCs was 54.3% (255/470), including 228 (89.3%) numerical and 27 (10.7%: 3 balanced and 24 unbalanced) structural abnormalities. Among the numerical abnormalities, trisomy was predominant (67.0%), followed by monosomy X (12.5%), polyploidy (8.2%), triple X (0.8%), and autosomal monosomy (0.8%). The overall sex ratio (male: female) among the 470 POCs with normal and abnormal karyotypes were 0.58 and 0.65, respectively. Trisomies were identified for each autosome, with the exceptions of 1, 3, and 19. Among the 171 autosomal trisomies, trisomy 16 was the most common (19.9%), followed by trisomy 22 (13.5%), trisomy 21 (12.3 %), trisomy 15 (9.9%), and trisomies 18 and 13 (5.3%). The frequency of chromosomal abnormalities decreased with gestational age and increased with maternal age, but only because of increases in trisomies and complex abnormalities. Conclusions: We have presented a large collection of cytogenetic data for SABs collected during the past 6 years and provided a database for prenatal genetic counseling of parents who have experienced SABs in Korea.
Purpose: Meconium-related ileus is common in preterm infants. Without proper management, it can cause necrotizing enterocolitis and perforation requiring emergent operation. This study was conducted to describe the efficacy and safety of ultrasound-guided Gastrografin enema at bedside for preterm infants with meconium-related ileus. Methods: Between March 2013 and December 2014, this study enrolled preterm infants with birth weight <1,500 g, who were diagnosed with meconium-related ileus requiring ultrasound-guided Gastrografin enema refractory to glycerin or warm saline enemas. Gastrografin was infused until it passed the ileocecal valve with ultrasound guidance at bedside. Results: A total of 13 preterm infants were enrolled. Gestational age and birth weight were 28.6 weeks (range, 23.9-34.3 weeks) and 893 g (range, 610-1,440 g), respectively. Gastrografin enema was performed around postnatal day 8 (range, day 3-11). The success rate was 84.6% (11 of 13 cases). Three of these 11 infants received a second procedure, which was successful. Among 2 unsuccessful cases, one failed to pass meconium while the other required surgery due to perforation. The time required to pass meconium was $2.8{\pm}1.5hours$ (range, 1-6 hours). The time until radiographic improvement was $2.8{\pm}3.4days$ (range, 1-14 days) after the procedure. Conclusion: Ultrasound-guided Gastrografin enema at bedside as a first-line treatment to relieve meconium-related ileus was effective and safe for very low birth weight infants. We could avoid unnecessary emergent operation in preterm infants who have high postoperative morbidity and mortality. This could also avoid transporting small preterm infants to fluoroscopy suite.
Background: This study was aimed at analyzing the preoperative conditions post-operative results indication and methods of surgical closure of patent ducturs arterio년 in prematures low birth weight infants and neonates. Patients and Methods: We retro-spectively studied two groups of patients (prematures group and neonates group) who underwent surgical closure of the patent ductus arteriosus between March 1995 and June 1998. Results: The premature group consisted of 9 patients(3 males and 6 females) Their mean gestational period was 30.7 weeks(ranging from 26 weeks to 33 weeks) mean age 27.8 days(11 days to 55 days) and mean body weight 1.56 kg. Prominent preoperative symptoms were dependency on mechanical ventilation generalized edema and hepatomegaly. We performed PDA ligation via thoracotomy in all premature patients. The neonate group consisted of 16 patients and their mean body weight was 3.75 kg. Major symptoms of this group was tachypnea and intercostal retraction resistant to medical treatment. We performed video-assisted PDA clipping to them all. There were no postoperative complications or operation-related mortality in both groups. Comparing the ratio of size of PDA(mm)/body weight(kg) the ratio of premature group (ligation through thoracotomy) was higher than that of neonate group ( video-assisted clipping) that is 3,89:1.21(p=0.03) Conclusion : We conclude that the surgical closure of PDA can be a safe method of treatment for prematures low birth weight infants and neonates with compromised general conditions. Choice of surgical technique depends on the surgeon's preference but there was a tend-ency to choose the ligation method through thoracotomy for patients with small body weight and large PDA.
Purpose: Maintaining body temperature is a key vital function of human beings, but little is known about how body temperature of highrisk infants is sustained during early life after birth. The aim of this study was to describe hypothermia in high-risk infants during their first week of life and examine demographic, environmental, and clinical attributors of hypothermia. Methods: A retrospective longitudinal study was done from January 1, 2013 to December 31, 2015. Medical records of 570 high-risk infants hospitalized at Neonatal Intensive Care Units (NICU) of a university affiliated hospital were examined. Body temperature and related factors were assessed for seven days after birth. Results: A total of 336 events of hypothermia (212 mild and 124 moderate) occurred in 280 neonates (49.1%) and most events (84.5%) occurred within 24 hours after birth. Logistic regression analysis revealed that phototherapy (aOR=0.28, 95% CI=0.10-0.78), Apgar score at 5 minute (aOR=2.20, 95% CI=1.17-4.12), and intra-uterine growth retardation or small for gestational age (aOR=3.58, 95% CI=1.69-7.58) were statistically significant contributors to hypothermia. Conclusion: Findings indicate that high-risk infants are at risk for hypothermia even when in the NICU. More advanced nursing interventions are necessary to prevent hypothermia of high-risk infants.
