The preoperative diagnosis of uterine torsion is very difficult due to the rarity of this disorder and its nonspecific clinical course. A primigravida woman visited our hospital with severe abdominal pain at 34 weeks of gestation. Emergency cesarean section was carried out due to development of fetal distress and severe abdominal pain. During the cesarean section, we noticed the uterus was rotated 180 degrees and the torsion was corrected after the delivery by making a vertical incision at the posterior uterine wall. High degree of suspicion and prompt management are important factors contributing to good prognosis of uterine torsion.

PURPOSE: We performed an analysis of the RSV outbreak in a postpartum center in Gyeongsangbukdo to provide preliminary data for health and hygiene management of postpartum care centers. METHODS: All of 22 newborns who were transferred to our hospital from a postpartum care center from December 2014 to January 2015 showed positive for RSV by viral culture and enrolled in the study group. To identify early symptoms in RSV infected newborn in the nursery 31 infants (1 month to 24 month of age) who were hospitalized in our hospital due to RSV infection during the same period were selected as control group and clinical symptoms were compared with the study group. A retrospective study was also performed on the newborns who were cared and not transferred to our hospital in the postpartum care center, as well as the facilities offered by the center. RESULTS: All of 22 neonatal patients who were transferred to our hospital had early symptoms of rhinorrhea and cough compared to control group. Rhinorrhea appeared 4.2±2.0 days before the admission, and cough occurred 1.0±1.1 days after rhinorrhea. The level of infection control specified by the law for general facilities relating to postpartum care centers was applied to the postpartum center, RSV infection was not controlled. Strict hand washing, individual equipment such as stethoscopes and exclusion of visitors with respiratory symptoms were done and infected neonates were segregated in separate air circulation system and cared by nurse-infant ratios from 1:1 to 1:2 depending on the needs of the individual neonates. Additional transmission was not observed after transfer to our hospital CONCLUSION: Neonates with cough and rhinorrhea were initial symptom for RSV infection in the postpartum center and should be evaluated for RSV infection during high risk season. Current guideline or support for infection control in postpartum center should be reevaluated for RSV infection control.

PURPOSE: The aim of this study is to determine the clinical characteristics of early onset sepsis (EOS) in micropreemie. METHODS: We retrospectively reviewed medical records of 107 extremely preterm infants born at 25 or less than 25 weeks of gestation and admitted to the neonatal intensive care unit of Samsung Medical Center from January 2013 to August 2015. Infants were divided into two groups based on the presence of culture-proven EOS in the first 7 days of life. Retrospective analysis of perinatal factors and laboratory findings within the first week of life was done between two groups. We compared the neonatal outcomes among two groups. RESULTS: Culture-proven EOS was diagnosed in 11 of 107 infants (10.3%). Main pathogen of EOS was Staphylococcus epidermidis (45.5%). There were no significant differences between control group and EOS group in gestational age, birth weight, Apgar score, delivery type and pathologic chorioamnionitis. Among 11 infants with EOS, 9 showed fetal tachycardia (P=0.001). And EOS group presented lower platelet count at 3rd day and 7th day of life than that of control group (P=0.033, P=0.045). Neonatal outcomes in EOS group were compatible with control group. Main cause of death was sepsis in EOS group. CONCLUSION: In micropreemie, EOS is important factor of mortality. Our data suggest that fetal tachycardia and low platelet count during the first 7 days of life were associated with EOS.

PURPOSE: The aim of this study was to evaluate the usefulness of thyroid function screening in preterm infants and the relation between thyroid hormone level, perinatal environment, and clinical presentation after preterm birth. METHODS: We retrospectively evaluated 46 preterm infants from March 2013 to December 2014, who had been screened for congenital hypothyroidism during the 1st week with thyroid stimulating hormone (TSH), triiodothyronine (T3) and free thyroxine (fT4) measured by the radioimmunoassay method. The effects of pregnancy associated maternal factors, gestational age, growth parameters, Apgar score, 1st meconium passage time, respiratory distress syndrome and apnea on thyroid hormone levels were assessed by Mann-Whitney U-test and multiple linear regression analysis. RESULTS: With advancing gestational age, T3 and fT4 displayed a tendency to increase. FT4 showed a positive correlation pattern with antenatal steroid therapy, corrected gestational age at examination and a negative correlation pattern with 1st meconium passage time and apnea (P<0.05). TSH displayed a positive correlation pattern with 1st meconium passage time, 5-minute Apgar score and a negative correlation pattern with sampling age (P<0.05). CONCLUSION: In the preterm period, both fT4 and TSH seems to correlate significantly with various perinatal factors and clinical presentation. We recommend that early fT4 screening should be included in the screening for hypothyroidism in preterm infants.

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.

PURPOSE: This study aims to compare the effectiveness and safety of ultrasound-guided contrast enema comparing with exploratory laparotomy for meconium plug syndrome in preterm infants. METHODS: Fifty-three preterm infants who were diagnosed with meconium plug syndrome among the neonates admitted to the Neonatal Intensive Care Unit of the Seoul National University Bundang Hospital from March 2008 to August 2015 were analyzed retrospectively. Four-teen infants among the 53 infants were excluded and Thirty-nine infants were analyzed. That time were divided into Period I and Period II. There was no pediatric radiologist and we couldn't try contrast enema in Period I. Pediatric radiologist was appointed and ultrasound guided contrast enema has been available in Period II. RESULTS: There were no specific differences of demographic characters between both Periods. Invasive procedure including contrast enema was increased in Period II than Period I (81% vs. 42%; P<0.05) and there were more exploratory laparotomy in Period I than in Period II (42% vs. 7%; P<0.05). Complications after treatment of meconium plug syndrome were more frequent in exploratory laparotomy groups than in ultrasound-guided contrast enema (57% vs. 0%; P<0.05) and total parenteral nutrition days were longer in laparotomy groups than in contrast enema groups (61±30 days vs. 31±13 days; P<0.05). CONCLUSION: We suggest that ultrasound-guided contrast enema with hyperosmolar water-soluble contrast is more therapeutic and safe therapy than exploratory laparotomy for meconium plug syndrome.
