A 24-year-old pregnant woman started to have severe hyperemesis gravidarum at 6 weeks' gestation. Six weeks later, dizziness, ataxia, visual disturbance, diplopia and confusion were developed. On admission, she presented ophthalmoplegia, nystagmus, deaeased tendon reflex, intention tremor, ataxia, confusion and memory disturbance. She was diagnosed to Wernicke-Korsakoff syndrome and 100mg of thiamine was administered intravenously daily till 28 weeks gestation and then intramuscularly. Her ocular symptns, together with neurological signs, were gradually improved. Memory disturbance slightly improved but remained at the time of delivery. The case will be presented in more details with a brief revie of literatures.

OBJECTIVES: The purposes of this study were to determine the usefulness of transvaginal ultrasonographic assessment of the uterine cervix and to compare the diagnostic performance of ultrasonographic and digital examination of the cervix in predicting a successful induction of labor. STUDY DESIGN: One hundred-one singleton term pregnancies without ruptured membranes admitted for the labor induction were included in this study. Digital examination and transvaginal ultrasonography of the uterine cervix were performed at the time of admission. Cervical parameters evaluated included cervical length, presence of funneling, funnel length, and funnel width. Labor induction was underwent by prostaglandin E2 (PGE2) vaginal suppository and/or pitocin intravenous infusion. Outcome variable was a successful labor induction within 48 hours after beginning of the induction. RESULTS: The prevalence of induction failure was 10.9% (11/101). Receiver-operator characteristic (ROC) curve and multiple logistic regression analysis indicated a significant relationship between the successful induction of labor and cervical length <3.1 cm. The diagnositic indices of endocervical length was superior to those of Bishop's cervical score in predicting a successful induction of labor. In patients with cervical length <3.1 cm, the labor was induced successfully with fewer tablets of PGE2, less use of pitocin infusion, and shorter induction-delivery interval. CONCLUSION: Transvaginal ultrasonographical examination of the uterine cervix is more accurate than digital examination of the cervix in the prediction of a successful induction of labor in term gestation.

OBJECTIVES: The purpose of this study was to determine the clinical significance of residual amniotic fluid volume, as measured by the amniotic fluid index(AFI), on the prediction of latency period and perinatal outcomes in patients with preterm premature rupture of the membranes(PPROM). METHODS: Study population consisted of 103 singleton pregnancies with PPROM between 24 and 34 weeks' gestation. Amniotic fluid index was determined using transabdominal ultrasound at admission. Latency period was defined as time interval in hours between admission and delivery. All medical records of mothers and neonates were reviewed. Spearman's rho rank correlation, receiver-operator characteristic(ROC) curve analysis, survival analysis and Cox's proportional hazard model were used for statistical analysis. RESULTS: There was a statistically significant correlation between latency period and AFI at admission. ROC curve analysis showed that AFI at admission had a significant predictive value in the prediction of latency period < 48 hours. Survival analysis demonstrated that AFI < 5.0 was strongly associated with the likelihood of shorter latency period, Cox's proportional hazard model indicated that AFI < 5.0 was a significant independent predictor for the occurrence of latency period < 48 hours even after adjustment of other independent variables. The patients with AFI <5.0 had a higher rate of cesarean section due to fetal distress than those with AFI > 5.0 but the incidence of chorioamnionitis was not significantly different between two groups. Comparing the perinatal mortality and neonatal morbidity including infectious morbidity between the neonates born to mothers with AFI <5.0 and those with AFI > 5.0, there was no significance after adjustment of gestational age at birth. CONCLUSION: AFI at admission has a significant correlation with latency period and predictive value in prediction of latency period in the patients with PPROM. AFI <5.0 is a independent predictor for the shorter latency period.

OBJECTIVE: Bronchopulmonary dysplasia (BPD) is one of the most frequent and clinically significant complications of prematurity and it has been widely accepted that immaturity, barotrauma, and oxygen toxicity are major factors in the etiology of BPD. However, recent studies showed that infection may also play a role in the pathogenesis of BPD and exposure to a prenatal inflammatory process may lead to lung injury and predispose to the subsequent development of BPD. The purpose of this study was to test the hypothesis that neonates with BPD had higher incidence of histologic chorioamnionitis than those in whom BPD does not develop. METHODS: A retrospective study was conducted to examine the relationship between histologic chorioamnionitis and the occurrence of BPD in neonate. We reviewed the hospital charts of 363 women and their neonates whose gestational age at birth were between 24 weeks and 35 weeks and recorded their pregnancy outcomes, the results of placental Biopsy, perinatal outcomes including the occurrence of BPD. RESULTS: 1. Neonates who developed BPD showed higher incidence of acute histologic chorioamnionitis. The relationship remained significant even after the adjustment for gestational age (odds ratio, 3.2: 95% confidence interval, 1.6-11.3: P<0.05). 2. Higher maternal serum CRP was also associated with increased incidence of histologic chorioamnionitis and BPD (P<0.05). 3. Neonates who developed BPD also had higher incidence of infectious morbidity such as early neonatal pneumonia and sepsis (P<0.05). CONCLUSION: These results suggest that histologic chorioamnionitis is closely related to the occurrence of BPD. This support the hypothesis that intrauterine infection may cause fetal lung injury and subsequent development of BPD.

6.Cervical Length During Pregnancy in Korean Women as Assessed by Transvaginal Ultrasound: A Prospective Longitudinal Study.
Korean Journal of Obstetrics and Gynecology 2002;45(11):1956-1960
OBJECTIVE: The aims of this study are to evaluate the longitudinal change in the cervix throughout pregnancy by transvaginal ultrasound and to establish a normogram of the cervical length in Korean pregnant women. METHODS: A prospective observational study was undertaken. Forty-eight women of singleton pregnancy without history of preterm delivery and medical or obstetrical complication were finally enrolled. Serial transvaginal ultrasound examination and the measurement of cervical length were performed at 12 weeks of gestation and every 4 weeks (until 28 weeks), every two weeks (until 36 weeks) and every week until delivery. ANOVA for repeated measures and paired t test were used for statistical analysis. RESULTS: The mean gestational age at delivery was 39.9 weeks. There was a significant quadratic correlation between gestational age and cervical length (y=-0.0038x(2)+0.1773x+1.6437, p<0.001). The cervical length was gradually increased until 24 weeks of gestation and then decreased during rest period of gestation. The measured values were distributed normally at each gestational age and the normogram of cervical length during pregnancy was presented in term of mean and standard deviation. There was no significant difference in cervical length between primipara and multipara. CONCLUSION: We presented serial measurements of cervical length throughout normal pregnancy. These values can be used as normative guidelines in assessment of cervical length during pregnancy.

7.Pro-inflammatory cytokine-induced nuclear factor-kappa B activity in prelabor and in-labor myometrial cells at term gestation.
Korean Journal of Obstetrics and Gynecology 2005;48(3):638-650
OBJECTIVE: The objectives of this study were to determine whether NF-kappa B-mediated pro-inflammatory cytokines signaling leads to COX-2 expression and PGE2 synthesis in human myometrial cells at term, and to compare cytokines-induced NF-kappa B activity and subsequent COX-2 expression and PGE2 synthesis between prelabor and in-labor myometrial cells. METHODS: Ten samples of human myometrium were obtained from 5 pregnant women with no labor and 5 in labor at term during cesarean section. Myometrial smooth muscle cells were harvested by cell culture and stimulated with TNF-alpha. PGE2 production and COX-2 expression were determined by ELISA and Western blotting analysis, respectively. NF-kappa B transcriptional activity was assessed by luciferase assay and by nuclear shifting using EMSA. RESULTS: Before the treatment of TNF-alpha, the levels of PGE2 production, COX-2 expression, and activity and nuclear shift of NF-kB in in-labor cells were higher than those in prelabor cells. By the stimulation of TNF-alpha, PGE2 output, COX-2 expression, and activity and nuclear shift of NF-kappa B increased in both of prelabor and in-labor cells. The increases of PGE2 production, COX-2 expression, and NF-kappa B activity were significantly greater in in-labor cells. CONCLUSION: Pro-inflammatory cytokines-induced COX-2 expression and subsequent PG synthesis, mediated by NF-kappa B, appears one of the important mechanisms of labor in term gestation.

OBJECTIVE: o determine the correlation between birth weight and the level of insulin-like growth factor(IGF)-I, -II and insulin-like growth factor binding protein(IGFBP)-3 in amniotic fluid at second trimester and to evaluate possibility whether the levels of IGF-I, II and IGFBP-3 could predict birth weight. METHODS: Sixty-seven samples of amniotic fluid in second trimester were analyzed for IGF-I, IGF-II, and IGFBP-3 by radioimmunoassay. Newborn birth weights were stratified arbitrarily as <25th percentile, 25-75th percentile, and >75th percentile. Linear regression analysis and Kruskal-Wallis test were used in well appropriately for statistical analysis. RESULTS: The level of IGF-I showed positive correlation with birth weight. However, the levels of IGF-II and IGFBP-3 showed no significant correlation with birth weight. The level of IGF-I were signifi cantly different among these groups. However, the levels of IGF-II and IGFBP-3 were not significantly different among these groups divided by the birth weight percentile. CONCLUSION: The levels of IGF-I in amniotic fluid at second trimester may be useful marker in predicting birth weight.
