OBJECTIVE: To investigate the change of maternal characteristics, delivery and neonatal outcomes in gestational diabetes mellitus (GDM) over recent 10 years and to identify the risk factors associated with adverse outcome. METHODS: Consecutive GDM patients (n=947) delivered in our institution were included. Research period was arbitrarily divided into 2 periods (period 1: from 2006 to 2010, period 2: from 2011 to 2015). Multiple pregnancies or preexisting diabetes were excluded. Maternal baseline characteristics, delivery and neonatal outcomes were reviewed. Fetal biometric findings by prenatal ultrasonography were collected. Adverse pregnancy outcome (APO) was defined by the presence of one of the followings; shoulder dystocia, neonatal macrosomia (>4 kg), neonatal hypoglycemia (< 35 mg/dL), respiratory distress syndrome (RDS), and admission to the neonatal intensive care unit (NICU) in term pregnancy. RESULTS: Period 2 was associated with older maternal age (34 vs. 33, P < 0.001) and higher proportion of GDM A2 compared to period 1 (30.9% vs. 23.0%, P=0.009). By univariate analysis, APO was associated with increased body mass index (BMI) at pre-pregnancy (23.4 kg/m² vs. 21.8 kg/m², P=0.001) or delivery (27.9 kg/m² vs. 25.8 kg/m², P < 0.001), higher HbA1c at diagnosis (5.6% vs. 5.3%, P < 0.001) or delivery (5.8% vs. 5.5%, P=0.044), and larger fetal biometric findings (abdominal circumference [AC] and estimated fetal weight, P=0.029 and P=0.007, respectively). Multivariate analysis showed pre-pregnancy BMI (odds ratio [OR], 1.101; 90% confidence interval [CI], 1.028–1.180) and fetal AC (OR, 1.218; 90% CI, 1.012–1.466) were independently associated with adverse outcomes. CONCLUSION: Our study demonstrated the trends and relevant factors associated with the adverse outcomes.

The neurogenic tumor of frequent occurrence in the presacral area is a schwannoma. Giant presacral schwannoma has a risk for anterior surgical approach because of its massive size and proximity to abundant vascularity of presacral region. We report a single stage posterior approach for total resection of a giant presacral schwannoma. A 40-year-old female patient experienced left buttock pain and tingling sensation at left S1 dermatome. Magnetic resonance imaging showed that the presacral huge mass at S1–3 level with osseous extension and structural remodeling in left sacral ala. The presacral mass was ranging in maximum diameter from 8.0 to 8.6 cm. S2 foramen laminectomy was performed to expose the mass. The tumor capsule and the root were carefully dissected away. The tumor was removed while preserving the capsule by dissecting the plane between the inner wall of the capsule and the tumor. The single stage posterior approach for presacral giant schwannoma is feasible, and it can be a good surgical alternative to prevent pelvic organ or vascular damage and anterior approach related dystocia and infertility.

Gestational diabetes mellitus (GDM) is traditionally defined as newly onset or detected carbohydrate intolerance during pregnancy. Unprotected exposure to high glucose levels during pregnancy is related to adverse pregnancy outcomes including fetal demise and intrauterine growth restriction associated with placental insufficiency. The most common complications related to GDM comprise macrosomia, shoulder dystocia, brachial plexus palsy, intrauterine fetal death and preeclampsia, polyhydramnios, preterm delivery, and increased cesarean section rate. Moreover, GDM may increase the chance of GDM recurrence in a subsequent pregnancy, impaired glucose tolerance or type 2 DM, and obesity or impaired glucose tolerance in the offspring. Therefore, proper obstetrical management and glucose control are always challenging and important. The aim of this article is to discern: 1) obstetric complications related to GDM diagnosed after pregnancy, 2) various methods of fetal surveillance, 3) proper timing for delivery and mode of delivery, 4) postpartum management for GDM patients and neonates, and 5) preconceptional counseling prior to a possible subsequent pregnancy.

Postpartum genital tract adhesions are unusual, and their cause has not been evaluated. However, severe dystocia and numerous pelvic examinations have been suggested as possible causes. Here, we report a case of vaginal adhesions following a difficult labor that presented as dyspareunia for 5 months. Pelvic examination and ultrasonography revealed a transverse vaginal septum that obstructed the vaginal cavity, and fluid collection proximal to this septum. The patient was successfully treated with surgical resection and administration of antibiotics.

OBJECTIVE: The objective of this study was to compare the neonatal outcomes and intrapartum events conducted by staff versus resident physicians in full term vaginal deliveries. METHODS: We divided study population (n = 5,007) into two groups: staff versus resident physicians. These two groups were sub-divided; faculty versus fellow and senior versus junior resident, respectively. The maternal characteristics, neonatal outcomes including Apgar score, admission to the neonatal intensive care unit and umbilical arterial pH and intrapartum event which was defined as the occurrence of shoulder dystocia and vacuum delivery were also investigated. RESULTS: There was no difference in neonatal outcomes between two groups. The group delivered by staff had a higher rate of nulliparity, large for gestational age and intrapartum events than the resident physician group. The subgroup analysis revealed a higher rate of vacuum delivery in the group delivered by faculty and senior members than the group delivered by fellows and junior members. CONCLUSION: There was no significant difference in neonatal outcomes between the two groups; staff versus resident physicians in full term vaginal deliveries in low-risk pregnant women. Also, experienced obstetricians might tend to participate in difficult labors and would prefer applying vacuum compared to the obstetricians with fewer experiences.

Pelvic organ prolapse complicating pregnancy is a rare clinical condition and its incidence is one in 10,000~15,000 deliveries. It is associated with multiparity, low socioeconomic status, inadequate perinatal care, maternal malnutrition, previous abdominal surgery, and weakness of pelvic muscular and connective tissue. It can cause cervical dystocia, which leads to cervical laceration, uterine rupture, maternal and fetal death. We experienced a case, first in Korea, of cervical swelling that developed during labor, prolapsed beyond the vaginal introitus and thus obstructed the birth canal. The patient underwent cesarean section and subsequently received MgSO4 topical therapy and resulted in complete resolution. We report this case with a brief review of literature.

OBJECTIVE: The purpose of this study is to compare the pregnancy outcomes of gestational diabetes mellitus (GDM) class A1 to those of GDM A2. METHODS: We performed a retrospective analysis of 99 women who were diagnosed as GDM during prenatal care and managed until delivery from March 1996 to September 2007. Subjects were grouped into GDM class A1 and class A2. The obstetric and neonatal outcomes were compared between the two groups. RESULTS: There were 57 cases of GDM class A1 and 42 cases of GDM class A2. Hemoglobin A1c level of GDM A2 group was significantly higher than GDM A1 group. We could not find any significant difference in obstetric (body mass index, hypertensive disorder, preterm delivery, preterm labor, preterm premature rupture of membrane) and neonatal outcomes (gestational age at delivery, macrosomia, shoulder dystocia, respiratory distress syndrome, transient tachypnea of neonate, sepsis, Apgar score, congenital anomaly) between the two groups other than increased frequency of cesarean delivery and admission to neonatal intensive care unit in GDM A2 group. CONCLUSION: After proper management, overall pregnancy outcomes of women with GDM class A2 are comparable to those with GDM class A1.

OBJECTIVE: The purpose of this study was to determine which factors influence the likelihood of successful trial of labor, to evaluate the risks of VBAC and to evaluate the criteria of dystocia and the safety of VBAC. METHODS: This retrospective study was peformed based on 61 pregnant women who succeeded VBAC, 37 VBAC failure women, 100 nulliparas and 100 multiparas. RESULTS: In clinical characteristics, the parity, the number of previous cesarean section, gestational age, estimated fetal body weight by ultrasonography, and neonatal body weight had notable differences between the success and the failure group. In obstetric and historical factors, cervical effacement, dilation, and Bishop score at admission, spontaneous labor and method of induction of labor had differences. Among these factors, estimated fetal body weight by ultrasonography, cervical effacement and augmentation of labor using oxytocin were the most prognostic factors affecting the success of VBAC. In VBAC group, the duration of active-phase, second phase and total duration of labor were 313.5, 36.4 and 350.2 minutes, which were significantly shorter than nulliparas, but longer than multiparas. CONCLUSION: The trial of labor after cesarean section will decrease repeat operation, if it is performed under exact understanding of successful prognostic factors and the unique time length of labor. It will contribute to increase advantages for mother and economic benefits.

Sacrococcygeal teratoma is often diagnosed by ultrasound in the prenatal period. The fetus may develop high-output heart failure due to limited cardiac pumping ability and anemia secondary to sequestration of blood volume in the tumor. Eventually, fetal hydrops or placentomegaly may develop and these complications carry a grave prognosis. Therefore, careful monitoring by serial USG is needed, and any evidence of fetal hydrops should trigger prompt delivery or fetal intervention. Recently, fetal MRI may be helpful in assessing the exact tumor size, content, and intraabdominal extent to optimize prenatal and postnatal management. We experienced a case sacrococcygeal teratoma diagnosed by prenatal ultrasonography and fetal MRI at 28 weeks of gestation. At 31 weeks of gestation, preterm labor with sudden aggravation of polyhydramnios developed, we delivered the baby by Cesarean section due to concerns about fetal dystocia by the mass. Tumor was removed successfully 6 days after birth, and was diagnosed as immature teratoma. Thirteen months after delivery, the infant is healthy without any evidence of recurrence. So we present this case with a brief review of literatures.

OBJECTIVE: To compare the perinatal outcomes of pregnant women with 100 g oral glucose tolerance test (OGTT) proven impaired glucose tolerance (IGT), with normal control and gestational diabetes mellitus (GDM) groups. METHODS: 159 pregnant women who had visited our medical center between March 2002 and March 2004, positive (> or = 140 g) for 50 g OGTT were included in this study. IGT was defined by the presence of one abnormal 100 g OGTT glucose value, and they were compared with the control group, and the GDM group(with at least 2 abnormal glucose values). The maternal and neonatal outcomes were assessed among three groups. RESULTS: Even though familial history of DM was significantly higher in the IGT and GDM group (p<0.001) compared with the control group, no difference was observed in the frequency of previous GDM. The rate of fetal macrosomi a (>4 kg) and hypoglycemia was significantly increased in GDM group than other groups. The difference in the frequency of i) large for gestational age birthweight (>90 percentile) ii) preterm delivery, iii) APGAR score (1-min and 5-min), iv) shoulder dystocia, and v) congenital anomalies among the three groups was not notable-however, the incidence of neonatal hyperbilirubinemia was significantly higher and duration of NICU admission is significantly longer in the IGT group, compared to the control group (p<0.001). In maternal outcomes, whereas no significant difference was observed concerning the frequency of i) polyhydramnios (>95%) ii) infections (genitourinary and surgical wounds) in the three groups, the prevalence of preeclampsia was significantly higher in the IGT (p=0.018) and GDM group (p=0.023), compared with the control group. CONCLUSION: Neonatal hyperbilirubinemia, as well as maternal preeclampsia were significantly elevated in the IGT group. The results obtained thus far demonstrate the possibility of the need for active perinatal care with therapeutic intervention in pregnant women with IGT.
