Objectives: The objective of this study is to analyze 1,068 cases of prenatal genetic amniocentesis and to compare the results with reported studies. Method: We analyzed 1,068 cases of midtrimester prenatal genetic amniocenteses from September 1994 to February 1999, and investigated the fetal chromosomal abnormality, obstetric outcomes and complications by the indications of genetic amniocentesis and prophylactic antibiotic use at the Department of Obstetrics and Gynecology, Ajou University School of Medicine. Results: Abnormal maternal serum markers were the most common indication of amniocentesis (57.7%) and the most common age distribution was 25-29 years (39.2%). One case of early amniocentesis (14 gestational weeks) was performed. The overall incidence of chromosomal aberration was 5.2% (56/1,068), of which there were 28 cases (50.0%; 28/56) of numerical aberrations and 28 cases (50.0%; 28/56) of structural aberrations. There were 50 cases (4.7%) of autosomal chromosomal aberrations and 6 cases (0.6%) of sex chromosomal aberrations. The pregnancy outcome was full-term delivery in 86.5%, preterm delivery in 7.6%, termination of pregnancy in 4.0%. There were no cases of serious complications including fetal death except for a case of self-limited amniotic fluid leakage(high leakage) in which the pregnancy was maintained. There were no significant differences between prophylactic antibiotics user group and non-user group in obstetric complications and outcomes. Conclusion: We could confirm that the trend in the indication of genetic amniocentesis had changed from advanced maternal age(35 year-old) toward abnormal maternal serum marker(triple test), and we recognized the importance of genetic amniocentesis according to the various antenatal screening tests of maternal serum marker, antenatal ultrasound, past history of fetal anomaly or family history of fetal chromosomal anomaly in the younger age groups(< 35 year-old) that are involved in more than half of the chromosomal anomaly. Further study will be needed to elucidate the efficacy of using prophylactic antibiotics in amniocentesis.

Objective : To evaluate the clinical outcomes of pregnancies showing one abnormal glucose tolerance test value. Method : We performed 50 gm glucose challenge test in 5,019 pregnant women at 24-28 weeks of gestation. In 1,170 women with plasma glucose levels over 130 mg/dL, 100 gm oral glucose tolerance tests (OGTTs) were performed at 28-32 weeks of gestation. In the 888 cases who were followed up, according to the National Diabetes Data Group (NDDG) criteria, 122 cases with one abnormal 100 gm OGTT value were divided into three groups (groups 1, 2, 3 : abnormal value after 1, 2, 3 hours, respectively). These were compared with 577 cases (control group) with normal 100 gm OGTT value, retrospectively. Result : The incidence of one abnormal glucose tolerance test value was 2.6%, and there were no cases where the fasting plasma glucose level only was elevated. The incidence (control, group 1, group 2, group 3 : 19.4%, 43.8%, 25.7%, 29.6%) of poor maternal outcomes which contain any one of preeclampsia, hydramnios, cesarean delivery for cephalopelvic disproportion or failure to progress or fetal distress was highest in group 1 (p=0.025). The incidence (15.8%, 43.1%, 14.3%, 21.1%) of poor perinatal outcomes which contain any one of fetal distress, Apgar score of 5 minute < 7, hypoglycemia, respiratory distress syndrome, small for gestational age, perinatal death was also highest in group 1 (p=0.009). Logistic regression analysis for poor maternal outcomes showed odds ratio of 2.83 (95% confidence interval 1.02-7.87) in group 1 and 2.08 (95% confidence interval 1.22-3.55) in group 3, and for poor perinatal outcomes odds ratio of 4.24 (95% confidence interval 1.02-17.52) in group 1 and 3.30 (95% confidence interval 1.45- 7.48) in group 3. Conclusion : Pregnancies complicated with one abnormal glucose tolerance test value, particularly the group showing abnormal glucose tolerance test value after 1 or 3 hour exhibited adverse maternal and perinatal outcomes.

The uterus with rudimentary horn occurs as a result of a lack of development during fetal life of the middle and lower parts of one of the Miillerian ducts, in which there is a failure of fusion of the two ducts, The incidence of this uterine anomaly is rare. Many cases of rudimentary uterine horn are not discovered since they do not become involved in a pregnancy, and thus remain symptomless and uncomplicated, and the diagnosis usually being made only with pregnancy with rupture. In this presentation, we describe a case of diagnosis and management of unruptured non-communicating rudimentary uterine horn pregnancy at the third trimester. The patient diagnosed by ultrasonography and MRI, was hospitalized for further evaluation and delivery under the impression of unruptured non-communicating rudimentary horn pregnancy. A living male infant weighing 1,930 gm was delivered by cesarean section at 33+l weeks due to impending preterm labor. Some articles concerned this subject were reviewed briefly to discuss relevant method of diagnosis, treatment, and clinical characteristics.

Objective: The aim of this study is to evaluate the value of the ultrasonographic cervical length after emergent and urgent cervical cerclage to prediction of preterm delivery in patients with incompetence of cervix. Methods: Fifty-one women who underwent emergent cervical cerclage and forty women who underwent urgent cervical cerclage were studied respectively. Receiver-operating characteristic (ROC) curve analysis, Pearson`s partial correlation coefficient, and multiple logistic regression analysis were used for statistical analysis. Results: The mean gestational age at admission was 21.2 ± 2.3 weeks in emergent cerclage group and 21.8 ± 3.2 weeks in urgent cerclage group. Postoperative mean cervical length was 17.6 ± 8.6 mm in emergent group and 21.8 ± 8.7 mm in urgent group. The diagnostic indices of postoperative cervical length (cut-off value 16.5 mm in emergent cerclage, 23.2 mm in urgency cerclage) by ROC curve were sensitivity of 65%, specifi city of 45%, positive predictive value of 17%, and negative predictive value of 8% in emergent cerclage group and in urgent cerclage group, sensitivity of 85%, specifi city of 50%, positive predictive value of 17%, and negative predictive value of 16%. Multiple logistic regression analysis indicated that postoperative cervical length was not an independent predictor of preterm delivery after adjustment of confounding factors in emergent group (P=0.65) in urgent groups (P=0.77). Conclusion: In the both groups, the postoperative cervical length was longer than preoperative. However the postoperative cervical length is not a useful predictor of preterm delivery in patients with emergent and urgent cervical cerclage.

Objective: The study was designed to ascertain a proper method of early diagnosis and treatment of ectopic pregnancy by analyzing its clinical and epidemiological characteristics. Methods: The medical records of patients who were diagnosed to ectopic pregnancy at Hallym medical center during the period from January 1, 2000 to December 31, 2007 have been reviewed. Results: The incidence of ectopic pregnancy was 7.3% (1,067) out of 14,519 deliveries. The most frequent age group was 26~30 (29.5%). Risk factors they had were previous histories of abdominal or pelvic surgery (37.0%), artificial abortion (30.8%), pelvic inflammatory disease (12%), and tubal sterilization (9.6%). Most frequent clinical symptoms were amenorrhea (88.7%), lower abdominal pain (81.2%), and vaginal spotting (60.0%). Percentage of patients with hemoglobin level over 10.0 gm/dL was 79% and below 8.0 gm/dL 3.9%. The clinical symptoms of ectopic pregnancy most commonly occurred after 6~8 weeks from last menstrual period (47%). Ectopic gestation was implanted on the fallopian tube in 89%, cornus in 7.2%, ovary in 1.1% and the cervix in 2.7%. Laparosopic surgeries were performed in 755 cases (71.6%) and laparotomies in 273 cases (25.9%) and dilatation and curettages in 26 cases (2.5%). Salpingectomy was performed most frequently (82.4%). Methotrexate (MTX) treatment was successful in 13 cases (1.21%). Conclusion: The early diagnosis of ectopic pregnancy is most useful when serum β-hCG and vaginal sonography are used together. Laparoscopy would be a preferred method because of its short hospitalization period and low complication rate compared with laparotomy in ectopic pregnancy treatment.

Objective : To evaluate perinatal outcomes in patients with abnormal 50 gm challenge test followed by normal 100 gm oral glucose tolerance test (OGTT) value. Methods : We examined the pregnancy outcomes of 423 women classified as the study group with abnormal 50 gm oral glucose challenge test (OGCT) followed by normal 100 gm OGTT based on NDDG criteria. If the 1-hour plasma glucose value of 50 gm OGCT was over 130 mg/dL, the patient was scheduled for a full 3-hour 100 gm OGTT. 50 gm OGCT and 100 gm OGTT were administered at 24-28 and 28-32 weeks' gestation, respectively. The control group constituted of 467 age- and body mass index (BMI)-matched negative screenees. We defined poor maternal outcomes as those suffering from any one of hydramnios or oligohydramnios, preeclampsia, cesarean delivery due to cephalopelvic disproportion, dystocia, or fetal distress. We also defined poor neonatal outcomes as those suffering from any one of hyperbilirubinemia, hypoglycemia, congenital anomaly, admission to neonatal intensive care unit due to respiratory distress syndrome, or perinatal mortality. Retrospective review of outcomes of these patients was performed. Student t-test, Fisher's exact test and chi-square test were used to determine the statistical significance. Results : There were no significant differences in demographic and obstetric characteristics between the control group and the study group. There were no significant differences in gestational age (38.7±1.5 vs 38.5±1.5 weeks), birth weight (3189.2±420.9 vs 3236.7±423.1 gm), between the groups. And there were no significant differences in preterm birth (6.2% vs 7.4%), large for gestational age births (4.5% vs 5.0%), intrauterine growth restriction (5.4% vs 4.3%) between the groups. There were no significant differences in poor maternal outcomes (15.6% vs 18.7%) and poor neonatal outcomes (3.9% vs 5.7%) between the groups. Conclusion : We conclude that abnormal value on 50 gm challenge test followed by normal 100 gm OGTT is not associated with adverse perinatal outcomes
