Comparison study on results of LAVH according to prior abdominal surgery / 대한산부인과학회지

OBJECTIVE: To evaluate the result of laparoscopically assisted vaginal hysterectomy (LAVH) according to history of prior abdominal surgery. METHODS: From January, 2003 to June, 2005, a total of 504 patients were performed LAVH at our Hospital. The patients were divided into 2 groups: Group of non prior abdominal surgery (Op. Hx(-) group) included 262 cases and group of prior abdominal surgery (Op. Hx(+) group) had 242 cases. We reviewed medical records and analyzed these cases regarding age, parity, weight, height, operation indication, operation outcome, duration of hospitalization and complication. RESULTS: There were no differences in terms of patients' mean age, parity, weight and height, and indications for surgery between the two groups. Mean operation time of Op. Hx(+) group (86.9+/-28.2 min) was longer than Op. Hx(-) group (80.7+/-20.0 min). There was no statistical difference on mean postoperative hemoglobin drop and mean uterine weight between the 2 groups. Mean hospital stay of Op. Hx(+) group (4.6+/-1.7 days) was longer than Op. Hx(-) group (4.3+/-0.9 days). The incidence of major surgical complications was higher in Op. Hx(+) group (10 cases - 4.1%) than Op. Hx(-) group (3 cases - 1.2%). In case of blader injury, Op. Hx(+) group (5 cases) was higher than Op. Hx(-) group (0 case). Op. Hx(+) group had 2 ureteral injuries and 1 rectal injury but there were no statistical differences. In case of trocar site bleeding, both group had 2 cases trocar site bleeding respectively. Op. Hx(-) group had 1 inferior vena cava injury but there was no statistical difference. CONCLUSION: At the time of LAVH, the incidence of bladder injury was higher in group of patients with history of prior abdominal surgery. So special attention should be paid to prevent bladder injury.

Clinical review of midtrimester amniocentesis / 대한산부인과학회지

OBJECTIVE: To compare the usefulness of prenatal screening tests for chromosomal abnormalities by analyzing the cytogenetic results of midtrimester amniocentesis METHODS: We reviewed a total of 1264 cases of midtrimester prenatal genetic amniocentesis performed from February 1997 to September 2003, of which accorded to indications of cytogenetic studies. Cytogenetic results were analyzed with the distribution of maternal age, indications of amniocentesis. RESULTS: The most common age of total subjects was in between 35-39 years (37.1%). The indications of amniocentesis were abnormal maternal serum marker (60.0%), advanced maternal age (34.8%), abnormal ultrasonographic findings (3.2%), in order. The overall incidence of chromosomal aberration was 3.9% (49/1264). No significant difference was found between the mean maternal age with and without abnormal fetal karyotype. According to indications, there was 12.5% (5/49) of chromosomal abnormalities in abnormal sonographic finding group, 5.2% (36/688) in abnormal maternal serum screening group and 2.4% (12/498) in advanced maternal age group. There was statistical significance (P=0.004) only in abnormal ultrasonographic finding group. CONCLUSION: Ultrasonography was become to be more important due to development of high resolution ultrasonography, skillful technique and awareness of sonographic markers. Ultrasonographic abnormality could be the most predictive marker for abnormal fetal karyotypes.

Factor V Leiden mutation in Korean women with pregnancy-induced hypertension / 대한산부인과학회지

OBJECTIVE: The purposes of this study was to evaluate the frequency of Leiden mutation (missense mutation in the factor V gene at exon 10, 1691 CGA to CAA) in Korean women with well characterized pregnancy-induced hypertension (PIH) compared with normotensive gravid women. METHODS: Genomic DNA from 121 PIH cases and 98 normotensive pregnant control cases were used for polymerase chain reaction (PCR). To genotype Leiden mutation (missense mutation in the factor V gene, exon 10 (1691 G to A)), primers (5'-TGC CCA GTG CTT AAC AAG ACC A-3', 5'-TGT TAT CAC ACT GGT GCT AA-3') were employed to make 267 base pair (bp) PCR product. There was an initial denaturation at 94 degrees C 5 min, followed by 30 cycles of one minute at 94 degrees C, one minute at 55 degrees C, and one minute at 72 degrees C. A 267 bp PCR product was further digested with Mnl I for 2 hour at 37 degrees C and analysed through 12% polyacrylamide gel electrophoresis to determine genotype. Allele 1691G yielded 37 bp, 67 bp, 163 bp fragment and allele 1691A yielded 67 bp, 200 bp fragment. RESULTS: We examined the genotypes of factor V of 121 Korean women with pregnant induced hypertension and 98 normal pregnant women. None of the 219 Korean women carried the factor V Leiden mutation. CONCLUSION: The factor V Leiden mutation is absent and not a common cause of PIH in Korean women.

Evaluation of NeonatalImmature Reticulocyte Fraction in Small-for-gestational Age Infant in Umbilical Cord Blood / 대한산부인과학회잡지

OBJECTIVE: To evaluate the immature reticulocyte fraction (IRF) by automated calculator that have played a role of predicting marker for hematopoiesis induced by perinatal asphyxia. METHODS: Hospital charts of 40 neonates with diagnosis of small for gestational age (SGA: birth weight <10 percentile) and 47 babies of appropriate for gestational age (AGA) who were delivered vaginally between May 8, 2000 and March 2, 2002 at department of Obstetric and Gynecology, Sanggye Paik Hospital, Inje university. About 5 cc in cord blood was collected immediately after delivery, the calculation of nucleated RBC (N-RBC)/100WBC by macroscopic exam and the evaluation of reticulocyte maturation by automated reticulocyte calculator (Sysmex SE 9000, TOA Medical Electronics Co., Ltd, Kobe, Japan) were performed, and made a comparative study of apgar score. RESULTS: The comparison between AGA and SGA infants, the mean values of cord blood sampling parameter N-RBC (3.53 +/- 4.89 vs 7.92 +/- 10.06, P=0.016), middle fluorescence ratio reticulocyte (MFR) (0.21 +/- 0.02 vs 0.23 +/- 0.03, P<0.001), high fluorescence ratio reticulocyte (HFR) (0.08 +/- 0.03 vs 0.12 +/- 0.03, P<0.001), IRF (0.28 +/- 0.03 vs 0.35 +/- 0.05, P<0.001) were obtained. All of the parameters were significantly different between SGA infants and normal infants and IRF was more valuable marker than N-RBC in evaluation of hematopoietic activity in SGA infants (multiple logistic regression analysis: P value 0.282 vs <0.001). CONCLUSION: Immature reticulocyte fraction by automated calculator is more accurate and confident marker better than N-RBC/100WBC by manual countingin evaluation of the fetal hypoxic induced hematopoiesis.

Clinical and Pathologic Study of Abnormal Uterine Bleeding in Premenopausal Women-To Evaluate the Prognostic Variables of Endometrial Hyperplasia / 대한산부인과학회잡지

OBJECTIVE: We performed this study to understand correlation between clinical aspects and pathological findings of abnormal uterine bleeding (AUB) and to evaluate the prognostic variables of endometrial hyperplasia. METHODS: We reviewed 500 premenopausal women with abnormal uterine bleeding who underwent endometrial biopsy from January 1996 to February 2003, retrospectively. Pregnant women, or women who had hematologic disease, or who used iatrogenic hormones were excluded. The age of women with AUB was mostly in the 5th decade (41.3 +/- 6.8). Body mass index (BMI) in most of women (69.6%) was between 18.6 and 24.9 (22.7 +/- 3.5). RESULTS: Among AUB menorrhagea (51.0%) was the most common bleeding pattern, and the next one was intermenstrual bleeding (38.0%). Histologic findings of endometrium were proliferative phase (34.0%), hyperplasia (26.4%), and seceretory phase (22.6%), in order of frequency. 79.0% (104 cases) of endometrial hyperplasia were simple hyperplasia, 16.0% (21 case) were complex hyperplasia, and 5.0% (7 case) were atypical hyperplasia. The associated diseases were myoma uteri, hypertension, and diabetes mellitus, in order of frequency. The endometrial hyperplasia was diagnosed in 46.4% of patients whose BMI was between 27.0-29.9, in 40% of patients between 30.0-34.9 and in 100% of patients whose BMI was 35.0 or more. The endometrial hyperplasia was diagnosed in 40.6% of patients with an endometrial thickness measured 15.1 mm to 20.0 mm, in 57.1% of patients with 20.1 mm to 25.0 mm, and in 100% of patients with 25.1 mm or higher. CONCLUSION: In premenopausal woman with AUB, the endometrial hyperplasia was highly associated with women whose BMI was 27.0 or higher, or with endometrial thickness measured more than 15.0 mm. Therefore endometrial biopsy should be taken in women with AUB whose BMI is high, or endometrial thickness is thick to exclude the endometrial hyperplasia.

Second-line Chemotherapy with Paclitaxel and Carboplatin for Patients with Recurrent Ovarian Carcinoma / 대한산부인과학회잡지

OBJECTIVE: This study is to investigate the efficacy and toxicity of paclitaxel plus carboplatin used as a salvage therapy. METHODS: Between June 2000 and November 2003, 10 patients aged 43-74 (median 55.0) with recurrent ovarian carcinoma were given combination chemotherapy including paclitaxel and carboplatin. The subjects received initial chemotherapy with paclitaxel plus cisplatin/carboplatin. On recurrence, paclitaxel was administered intravenously at a dose of 175 mg/m2 with carboplatin by AUC 5 every 3 weeks. The median treatment cycle was 10 cycles (range, 1 to 15 cycles). Recurrence of ovarian carcinoma was determined by elevation of serum CA-125, or radiologic imaging. Responses and toxicities were evaluated according to Gynecologic Oncology Group criteria and Common Terminology Criteria for Adverse Events from NCI (National Cancer Institute). RESULTS: The overall clinical response rate was 60.0% (6/10). Better response was observed in patients who were sensitive with initial chemotherapy. Anemia was the most frequent complication. CONCLUSION: Paclitaxel and carboplatin has been shown to be a feasible agent in patients with recurrent ovarian cancer.

Gemcitabine as second-line chemotherapy in patients with recurrent epithelial ovarian cancer: Review of four cases / 대한산부인과학회잡지

Adjuvant multiagent chemotherapy with platinum and paclitaxel after optimal cytoreductive surgery decisively improved survival rates of patients with epithelial ovarian carcinoma. However, more than two- thirds of patients with advanced disease will encounter tumor progression, underlining the need for effective second-line strategies. Continued efforts to discover new active agents for the treatment of patients with ovarian carcinoma had identified gemcitabine. Four patients with epithelial ovarian carcinoma, who were treated in Inje University Sanggye Paik Hospital and recurred thereafter received gemcitabine 1,000 mg/m2 as a 30 min intravenous infusion on days 1, 8, and 15, which was repeated every 28 days. The disease progressed in two patients, while one showed stable disease and another reached complete response. One patient expired of disease two months after the completion of therapy. Grade 3 leukopenia was successfully managed using G-CSF. Regrowth of hair lost during previous chemotherapy occurred in all subjects. We report four cases of advanced recurrent ovarian carcinoma which were treated with gemcitabine.

Maternal Morbidity and it's Risk Factors in Eclamptic Woman / 대한산부인과학회잡지

OBJECTIVE: To identify risk factors for maternal morbidity in eclamptic woman. METHODS: A retrospective analysis was performed on the record of eclamptic woman during from August 1989 to February 2002. Univariate analysis was used to determine which of the independent variables were significantly different between two groups (antepartum vs postpartum). RESULTS: The incidence of eclampsia was 1 in 1,795 deliveries and the maternal mortality rate was 4.3%. Maternal complications associated with eclampsia were abruptio placentae (13.0%), pulmonary edema (26.1%), acute renal failure (39.1%), HELLP syndrome (30.4%), disseminated intravascular coagulopathy (8.7%), neurologic sequelae (8.7%), maternal death (4.3%). One patient died from disseminated intra- vascular coagulopathy, sepsis, and multiorgan failure after postpartum eclampsia. Women with antepartum eclampsia had higher incidence of acute renal failure (44.4% vs 20%) and HELLP syndrome (33.3% vs 20%) than did in women with postpartum eclampsia. Conversely, women with postpartum eclampsia had higher incidence of disseminated intravascular coagulopathy (6.7% vs 20%) and neurologic sequelae (6.7% vs 20%). CONCLUSION: Early detection and management of preeclampsia can prevent the eclampsia and maternal mortality and morbidity.

Study on Umbilical Cord Plasma Leptin in Preeclamptic and Normal Pregnant Women / 대한산부인과학회잡지

OBJECTIVE: Leptin, the protein encoded by the Ob gene in the adipose cell, is produced by the placenta during pregnancy and materanal serum leptin is increased in preeclampsia. The objective of this study was to compare umbilical cord plasma leptin level between infants of mothers who experienced preeclampsia and infants of control subjects and to understand the physiology of leptin. METHODS: Leptin concentrations were measured in cord blood at birth using a specific radioimmunoassay employing human recombinant leptin (Human leptin RIA kit; Linco Research, Inc. U.S.A.). We compared cord plasma leptin between preeclamptic (n=17 women) and normal pregnancies (n=21 women). RESULTS: Gestational age is the only one significant variable among the demographic variables (P=0.011). There was no statistically significant difference in cord plasma leptin level between infants of mothers who experienced preeclampsia and infants of control subjects, but preeclampsia group had slightly lower leptin levels than control subjects (Control subjects: 4.8 [3.7-7.9] ng/ml, Preeclamptic women: 2.7 [2.3-6.8] ng/ml, P=0.142). There was also no difference in the leptin value adjusted for different gestational age, or ratio between cord plasma leptin level and gestational age (Control subjects: 0.017 [0.013-0.018], Preeclamptic women: 0.010 [0.008-0.025], P=0.131). CONCLUSION: We found no difference between umbilical cord plasma leptin in infants of mothers who had preeclampsia and umbilical cord plasma leptin in infants of control subjects, but insignificantly lower levels of umbilical cord plasma leptin in infants of mothers who had preeclampsia. It suggest that maternal serum concentration do not correlate with cord leptin concentration and dysregulation of leptin metabolism and/or function in the placenta may be implicated in the pathogenesis of preeclampsia.

A Case of Advanced Squamous Cell Carcinoma Arising in Mature Cystic Teratoma of the Ovary / 대한산부인과학회잡지

Mature cystic teratoma comprises approximately 10-20% of all ovarian neoplasms and malignant transformation from mature cystic teratoma is reported to be less than 2%. Squamous cell carcinoma is the most frequent malignancy (80%) arising in mature cystic teratoma followed by sarcoma (7-8%), adenocarcinoma (6-7%), carcinoid tumor, melanoma, choriocarcinoma (1-2%). Prognosis of squamous cell carcinoma in mature cystic teratoma is reported much poorer than that of epithelial ovarian cancer with the same stage. We experienced one case of squamous cell carcinoma arising in mature cystic teratoma.

Effects of Oligohydramnios on Perinatal Outcome and Latency Period in Patients with Preterm Premature Rupture of Membranes / 대한주산의학회잡지

OBJECTIVES: To examine the effects of the oligohydramnios on perinatal outcome and latency period in patients with preterm premature rupture of membranes. METHODS: We performed a retrospective analysis of 98 singleton pregnancies complicated by preterm premature rupture of membranes, with delivery between 26 and 35 weeks' gestation. Amniotic fluid index was determined using transabdominal ultrasound at admission. All medical records of mothers and neonates were reviewed. Oligohydramnios was defined as amniotic fluid index less or equal to 5.0 cm and latency period was defined as time interval from membrane rupture to delivery. Chi-spuare test, Fisher's exact test, Student-t test, Mann-Whitney U test were used for statistical analysis. RESULTS: 1) Of the 98 patients, 59 patients(60%) were oligohydramnios group(AFI5.0). Both groups were similar with respect to selected dermographics, gestational age at rupture of the membranes, chorioamnionitis, 1 min Apgar score and 5 min Apgar score. Patients with oligohydramnios demonstrated a lower gestatoinal age at birth and lower birth weight. There were no statistically significant correlations in neonatal morbidity and perinatal mortality between both groups. 2) For comparing latency period, we excluded deliveries of Cesarean section or induction. Comparing the remained group(25 patients), median of latency period in oligohydramnios group were 41.5 hours and median of latency period in non-oligohydramnios group were 44 hours. There were no statistically significant correlations in oligohydramnios and latency period. CONCLUSION: There were no significant effects of the oligohydramnios on poor perinatal outcome and latency period in patients with preterm premature rupture of membranes

Analysis of A1166C Polymorphism in Type I Receptor for Angiotensin II Gene with Pregnancy Induced Hypertension(PIH) in Korean Women / 대한주산의학회잡지

BACKGROUND/AIM: Recent studies have suggested an association between genetic background of renin-angiotensin(RA) system and the pathogenesis of pregnancy induced hypertension(PIH). Even though various single nucleotide polymorphism(SNP) such as M235T, T174M polymorphism in angiotensinogen gene(AGT) and I/D polymorphism in angiotensin I-converting enzyme gene(ACE) have been studied extensively among essential hypertension and PIH in various population, its association was still inconclusive. Previous studies within Korean PIH patients also revealed that M235T or T174M single nucleotide polymorphism in AGT gene or I/D polymorphism in ACE gene were not linked tightly with PIH. However, recent studies on angiotensin II type I receptor(AT1) polymorphism A1166C with PIH in Polish or in Chinese suggested its possible correlations to a pathogenesis of PIH. Thus the aim of the present study was to determine the frequency of genotypes of A1166C mu-tation in women with PIH and to establish the role of this polymorphism on the susceptibility to the PIH development. PATIENTS AND METHODS: We have analysed 121 women with PIH and 98 healthy normotensive gravid women as a control. Genomic DNA was used for PCR. To genotype the A1166C polymorphism in angiotensin II receptor(AT1) gene, primers(sense 5'-CGA CTA CTG CTT AGC ATA-3', antisense 5'-GCA CCA TGT TTT GAG GTT-3') were employed to make 546bp PCR product. There was an initial denaturation at 94degrees C 5 minutes, followed by 30 cycles of one minute at 94degrees C, one minute at 58degrees C, and two minutes at 7degrees C. A 546bp PCR product was further digested with DdeI for 2 hour at 37degrees C and analysed through 2% agarose gel electrophoresis to determine genotype. Allele C1166 yielded 435bp, 111bp fragment and allele A1166 yielded intact 546 bp fragment RESULTS: We found that frequency of genotype A1166/C1166 and A1166/A1166 in PIH were 9.9% (12) and 90.1%(109), while in controls were 17.3%(17) and 82.7%(81). There was no statistical significance between development of PIH and A1166C polymorphism in type I receptor for Angiotensin II. Homozygous mutated genotype(C1166/C1166) was not detected in this study. CONCLUSION: Our results found no possible correlation of A1166C polymorphism in angiotensin II receptor(AT1) with PIH in Korean and found that allele C might behave as a protective factor rather than as a risk factor in the pathogenesis of PIH. We suggest a large-scale study to evaluate relevance to this polymorphism for PIH.

The Effect of VEGF (Vascular endothelial growth factor) on Endothelial Cells in Pathogenesis of Preeclampsia / 대한산부인과학회잡지

OBJECTIVE: Preeclampsia is primarily a disorder of the maternal endothelium. The objective of this study was to assess the effect of VEGF on human umbilical vein endothelial cells (HUVEC) in vitro. METHODS: The serum concentrations of VEGF in women with preeclampsia and normotensive pregnant women were measured with a sensitive and specific enzyme immunoassays. After HUVEC were isolated and cultured in vitro, these HUVEC were stimulated with VEGF, sera from women with preeclampsia and normotensive pregnant women for 24 hours. And then prostacyclin levels were measured. RESULTS: The serum concentrations of VEGF were significantly higher in women with preeclampsia than in normotensive pregnant women. Vascular endothelial growth factor induced a significant concentration- dependent increase in prostacyclin production. HUVEC stimulated with sera from women with preeclampsia showed an increase in production of prostacyclin. VEGF concentration in serum was correlated with prostacyclin production by the stimulated cells. CONCLUSION: VEGF may be one of the circulating factors that cause the alteration in endothelial function and the high serum concentration of VEGF is thought to be important in the pathogenesis of preeclampsia.

Multiple dose methotrexate chemotherapy in suspected medical treament failure of ectopic pregnancy / 대한산부인과학회잡지

OBJECTIVE: The purpose of this study was to determine the efficacy of multiple dose methotrexate (MTX) chemotherapy approved as a primary treatment of ectopic pregnancy in suspected medical treatment failure of ectopic pregnancy. METHODS: This study included 77 hemodynamically stable high risk ectopic pregnants diagnosed from January 1995 to June 2000 at department of Obstetrics & Gynecology, Sanggye Paik hospital, Inje university. High risk criteria of our study were adnexal ectopic mass 3.5 cm or serum-hCG 4,000 mIU/ml or presence of fetal heart beat(FHB) or presence of peritoneal fluid and fresh blood on culdocentesis. Statistics were analyzed with 2-test, Student t-test and odds ratio of each risk factors. RESULTS: The response rate of multiple dose MTX chemotherapy was 85.7%(66/70). There was no statistically difference of risk factors between success and failure group except fetal heart beat. Among 11 failure patients, there were 3 patients with adnexal ectopic mass 3.5 cm (odds ratio=1.4, 0.3~5.7), 3 patients with presence of FHB, 7 patients with presence of peritoneal fluid(odds ratio=1.0, 0.3~3.8), 8 patients with serum-hCG 4,000 mIU/ml (odds ratio=2.8, 0.7~11.6). CONCLUSION: There results suggest that multiple dose MTX chemotherapy can be treated regardless of ectopic mass size, presence of pretoneal fluid, serum beta-hCG level. But we must pay attention to treat ectopic pregnancy with presence of fetal heart beat.

The relationship between amniotic fluid tumor necrosis factor- , histologic chorioamnionitis, and congenital sepsis in preterm labor / 대한산부인과학회잡지

OBJECTIVE: Our purposes were (1) to determine whether amniotic fluid concentrations of tumor necrosis factor- are of value in the diagnosis of histologic chorioamnionitis of preterm placenta and in the prediction of congenital sepsis in patients with preterm labor and intact membranes and (2) to compare the diagnostic performance of placental histologic finding and amniotic fluid culture with that of amniotic fluid tumor necrosis factor- for this outcome variable. METHODS: The relations among placental histologic finding, perinatal outcome, amniotic fluid culture, and amniotic fluid tumor necrosis factor- concentrations were examined in 61 consecutive patients with preterm labor and intact membranes who delivered preterm neonates within 72 hours after transabdominal amniocentesis. Tumor necrosis factor- was determined by enzyme-linked immunosorbent assays. Mann-Whitney U test, Fisher's exact test, receiver-operator characteristic curve, and multiple logistic regression were used for analysis. RESULTS: 1) Women with acute histologic chorioamnionitis had significantly higher median amniotic fluid tumor necrosis factor- concentrations than those without histologic chorioamnionitis (median 83.2 pg/ml, range 1.4 to 7241 pg/ml vs median 1.6 pg/ml, range 0 to 59.9 pg/ml, p or =4.6 pg/ml had a sensitivity of 88% (28/32) and specificity of 80% (23/29) in the diagnosis of acute histologic chorioamnionitis. 2) Amniotic fluid concentrations of tumor necrosis factor- were significantly higher in neonates with congenital sepsis than in those without congenital sepsis (median 227.5 pg/ml, range 1.2 to 7241 pg/ml vs median 3.8 pg/ml, range 0 to 735 pg/ml, p or =41 pg/ml had a sensitivity of 82% (23/29) and specificity of 79% (38/48) in the prediction of congenital sepsis. 3) Multiple logistic regression indicated that elevated amniotic fluid tumor necrosis factor- (> or =41 pg/ml) was the only independent predictor of congenital sepsis (odd ratio 12.9, 95% confidence interval 1.3 to 125.3, p<0.05) after correction for known confounding variables [i.e., low gestational age at birth (< or =32 weeks), positive amniotic fluid culture, histologic or clinical chorioamnionitis, low Apgar score (<7)]. CONCLUSION: Test of amniotic fluid tumor necrosis factor- is of value in the antenatal diagnosis of histologic chorioamnionitis and congenital sepsis in patients with preterm labor and intact membranes. Amniotic fluid tumor necrosis factor- is a better independent predictor of congenital sepsis than placental histologic finding or amniotic fluid culture.

Effects of preeclampsia on labor induction with prostaglandin E2 and oxytocin / 대한산부인과학회잡지

OBJECTIVE: The purposes of this study were 1) to determine whether preeclampsia itself affects failure of labor induction with prostaglandin E2 and oxytocin and 2) to investigate risk factors for failed induction in women with preeclampsia. METHOD: Fifty preeclamptic women and 175 nonpreeclamptic women requiring labor induction were studied prospectively. Intravaginal prostaglandin (PG) E2 tablet (Dinoprostone, The Upjohn company, 3 mg) followed by a second dose if the cervix assessed 6 hours later was 5 or less of Bishop score, and oxytocin were used for labor induction. Women with rupture of membrane, spontaneous contraction resulting in cervical change or an initial cervical examination showing more than 2 cm dilatation and 50% effacement were excluded. Statistics were analyzed with 2 test, Student t test, and multiple logistic regression. RESULTS: 1) The women with preeclampsia had a significantly higher rate of failed induction than did those without preeclampsia [24% (2/50) versus 9% (16/175); p <0.05]. However, the women with preeclampsia had a higher rate of the use of magnesium sulfate, and were more likely to decrease gestational age at induction and increase maternal weight than those without preeclamp sia (p <0.0001, respectively). There were no significant differences in prevalence of nulliparity and low initial Bishop score (< or =3) between the women with and without preeclampsia. 2) Multiple logistic regression showed that preeclampsia itself was not associated with failed induction after correction of known confounding variables (odds ratio 0.22, 95% confidence interval 0.03-2). 3) In women with preeclampsia, the use of magnesium sulfate only was associated with increased risk of failed induction analyzed by multiple logistic regression(odds ratio 38.5, 95% confidence interval 1.6-897). Maternal weight with 70 kg or more was associated with increased risk of failed induction, but it is not statistically significant (p=0.055). CONCLUSIONS: 1) The risk of failed induction is increased in women with preeclampsia, but not by preeclampsia itself but by the use of magnesium sulfate, prematurity, and increased maternal weight secondary to preeclampsia. 2) The use of magnesium sulfate is independent risk factor for failed induction in women with preeclampsia.

Prenatal diagnosis of fetal intussusception: A case report / 대한산부인과학회잡지

Fetal intussusception is not common and the underlying mechanism triggering the event is not known at present. There are few reports of successful diagnosis in fetus with prenatal ultrasongraphy. It may be detected by meconium peritonitis. Meconium peritonitis is a nonbacterial foreign body reaction or chemical inflammation by intestinal perforation result from intestianl atresia, intussusception and fetal bowel obstruction. Recently we experienced a 33+1 weeks of gestational fetus with fetal intussusception who had prenatal ultrasonographic detection with meconium peritonitis, and the infant was underwent postnatal laparotomy. We present this case with a brief review of literature.
