ABSTRACT
OBJECTIVE: This study aimed to examine clinical practice patterns in the management of pregnant women admitted with threatened preterm labor (TPL) in Korea. METHODS: Data from women admitted with a diagnosis of TPL were collected from 22 hospitals. TPL was defined as regular uterine contractions with or without other symptoms such as pelvic pressure, backache, increased vaginal discharge, menstrual-like cramps, bleeding/show and cervical changes. Data on general patient information, clinical characteristics at admission, use of tocolytics, antibiotics, and corticosteroids, and pregnancy outcomes were collected using an online data collections system. RESULTS: A total of 947 women with TPL were enrolled. First-line tocolysis was administered to 822 (86.8%) patients. As a first-line tocolysis, beta-agonists were used most frequently (510/822, 62.0%), followed by magnesium sulfate (183/822, 22.3%), calcium channel blockers (91/822, 11.1%), and atosiban (38/822, 4.6%). Of the 822 women with first-line tocolysis, second-line tocolysis were required in 364 (44.3%). Of 364 with second-line, 199 had third-line tocolysis (37.4%). Antibiotics were administered to 29.9% of patients (284/947) with single (215, 22.7%), dual (26, 2.7%), and triple combinations (43, 4.5%). Corticosteroids were administered to 420 (44.4%) patients. Betamethasone was administered to 298 patients (71.0%), and dexamethasone was administered to 122 patients (29.0%). CONCLUSION: Practice patterns in the management of TPL in Korea were quite various. It is needed to develop standardized practice guidelines for TPL management.

BACKGROUND: The prevalence of group B streptococcus (GBS) among pregnant women and neonates in the Republic of Korea has increased. In addition, rates of resistance to antibiotics recommended for pregnant women allergic to penicillin, such as clindamycin and erythromycin, have increased. The aim of this study was to evaluate subject characteristics associated with GBS resistance to clindamycin and erythromycin. MATERIALS AND METHODS: A total of 418 clinical isolates from pregnant women in Korea were screened for antibiotic resistance from January 2006 to December 2011. Sociodemographic information, medical and obstetric history, and details of events during the previous 2 weeks were recorded using a standardized questionnaire. RESULTS: The resistance rates were 39.5% for clindamycin and 23.0% for erythromycin. In multiple logistic regression analysis, the subject characteristic significantly associated with resistance to both antibiotics was a history of symptomatic sore throat in the 2 weeks before obtaining the specimen (erythromycin: odds ratio [OR]: 2.13, 95% confidence interval [CI]: 1.10 to 4.13; clindamycin: OR: 2.31, 95% CI: 1.21, 4.42). Premature rupture of membranes (PROM) had an association of borderline significance. CONCLUSIONS: In the urgent treatment of GBS-colonized pregnant women, the subject's history of previous sore throat and PROM should be considered when choosing appropriate antibiotics.

OBJECTIVES: To identify obstetric and maternal factors related to Group B Streptococcus (GBS) colonization in pregnant women in Korea. METHODS: The study was conducted between the years 2006-2008 in four hospitals, Cheil and Eulji hospital in Seoul, and Motae and Eulji hospital in Daejeon. We recruited 2,644 pregnant women between 35 to 37 weeks of gestation who had visited for antenatal care. Participants completed a questionnaire, and urine, vaginal and rectal specimens were obtained and cultured using selective broth media. After delivery, medical records were reviewed. RESULTS: GBS colonization was significantly associated with hospital, age group, education, frequency of pregnancy, and premature rupture of membranes (PROM, more than 18 hours). After adjustment for other variables, Cheil hospital (odds ratio [OR], 2.05; 95% confidence interval [CI], 1.20-3.52), and the first pregnancy (OR, 2.32; 95% CI, 1.12-4.81) remained significant. History of vaginitis showed marginal significance (OR, 1.50; 95% CI, 0.98-2.29). CONCLUSION: To prevent GBS infection of neonates, clinicians should be alert to the potentially higher risk of GBS colonization in pregnant women in their first pregnancy, and women with premature rupture of membranes (PROM) (18 hours+) or who have a history of vaginitis.

The prevalence of group B streptococcus (GBS) among pregnant women and disease burdens in neonates and adults are increasing in Korea. Colonizing isolates, collected by screening pregnant women (n=196), and clinical isolates collected from clinical patients throughout Korea (n=234), were serotyped and screened for antibiotic resistance. Serotype III (29.8%) and V (27.7%) predominated, followed by Ia (17.0%). Antibiotic resistance was higher among clinical than colonizing isolates for erythromycin (35.1% and 26.9%; P=0.10) and for clindamycin (49.4% and 42.1%; P=0.17). erm(B) occurred in 91.9% of erythromycin resistant isolates, and 84.0% of isolates resistant to clindamycin. Only five isolates (4.2%) resistant to erythromycin were susceptible to clindamycin; by contrast, and unique to Korea, 34% of isolates resistant to clindamycin were erythromycin susceptible. Among these 60 erythromycin-susceptible & clindamycin-resistant isolates, 88% was serotype III, and lnu(B) was found in 89% of strains. Four fifths of the serotype V isolates were resistant to both erythromycin and clindamycin. Further characterization of the genetic assembly of these resistance conferring genes, erm(B) and lnu(B), will be useful to establish the clonal lineages of multiple resistance genes carrying strains.
ABSTRACT
OBJECTIVE: To determine the accuracy and usefulness of prenatal ultrasonographic and molecular genetic diagnosis in detection of skeletal dysplasia. METHODS: This study was based upon data of the 17 cases of skeletal dysplasia diagnosed by prenatal ultrasound and 7 cases by molecular diagnosis performed among the 17 cases and the 2 cases who has familial skeletal dysplasia by molecular diagnosis during the first trimester at Ewha and Eulji University from March 1998 to August 2005. A final diagnosis was sought on the basis of radiographic studies, molecular testing, or both. RESULTS: The mean gestational age at diagnosis was 24.9 weeks (range, 17 to 35 weeks). Nine cases were diagnosed before 24 weeks. A final diagnosis was obtained in 16 cases (94.1%). There was 1 false-positive diagnosis. The antenatal diagnosis was correct in 14 cases (82.4%). The 8 cases were prenatally confirmed and 1 case was postpartum confirmed using molecular genetic testing and accurate antenatal diagnosis and prediction was done. We were able to rule out skeletal dysplasia through chorionic villus sampling during the first trimester in the 2 cases with the family history with skeletal dysplasia. CONCLUSION: Prenatal diagnosis of skeletal dysplasia can be a considerable diagnostic challenge. However, skeletal dysplasia is correctly diagnosed on the basis of prenatal meticulous ultrasound and antenatal prediction of lethality was highly accurate. Using prenatal molecular diagnosis, skeletal dysplasia can be diagnosed at first trimester of pregnancy and nonlethal skeletal dysplasia can be confirmed when prenatal ultrasound was nonspecific.

OBJECTIVE: To compare the clinical effectiveness of transvaginal radiofrequency myolysis of the patients with leiomyomas and the patients with adenomyosis which have similar clinical symptoms. METHODS: From May 2005 to May 2006 at Eulji university hospital, 108 women who were diagnosed of leiomyoma and adenomyosis had undergone transvaginal radiofrequency myolysis. Before and after the procedure size, number of uterine myomas, location and the volume of the leiomyomas and adenomyosis were measured by ultrasound. And on every visit after the procedure improvement of the symptom was checked by questionnaire of the symptom and life quality. Using Wilcoxon signed ranked test, the statistical significance was proved and the P value lower than 0.05 was judged to be significant. RESULTS: 76 women with leiomyoma who had undergone transvaginal radiofrequency myolysis, were followed up 1 month, 3 months, 6 months and 9 months after the procedure. The average maximal diameter of the myoma was decreased by 14.6%, 23.3%, 30.6%, 33.6% respectively, and the average volume was decreased by 35.7%, 53.3%, 67.3%, 72.2% respectively. 32 women with adenomyosis who had undergone transvaginal radiofrequency myolysis were followed up, at the same period after the procedure. The average maximal diameter of the adenomyosis was decreased by 8.9%, 13.6%, 14.6%, 11.9% respectively, and the average volume was decreased by 22.6%, 30.0%, 32.3%, 28.4% respectively. Before and after the procedure the symptom score was 62.3, 52.2, 40.6, 32.6, 28.6 respectively, and the quality of life score was 68.9, 78.1, 82.9, 85.7, 87.3 respectively in the leiomyoma group. In the adenomyosis group, before and after the procedure the symptom score was 77.7, 37.6, 30.6, 54.4, 67.5 respectively, and the quality of life score was 48.1, 76.5, 85.5, 66.5, 55.1 respectively. CONCLUSION: Transvaginal radiofrequent myolysis had benefits in conserving the uterus, and was less invasive, and had great effect on the reducing the size of the leiomyoma and improving the symptoms, and also returning to normal life pattern was earlier. But in women with adenomyosis the symptoms were worsened after approximately 6 to 9 months after the procedure. Therefore additional research and follow-up is required and a strict criterion is needed.

OBJECTIVE: Recently, selective termination is employed in multifetal pregnancies, in the presence of an abnormal fetus, or in the complication of twin pregnancies. The purpose of this study is to evaluate effectiveness, safety of the tailored selective termination in multifetal pregnancies. METHODS: This study was retrospective and involved six cases. Indication of termination were 3 cases of structural anomalies (anencephaly, encephalocele, body stalk anomaly), 1 case of chromosomal anomaly (21 trisomy) and 2 cases of monochorionic twin complications (acardiac twin, twin to twin transfusion syndrome). RESULTS: We used KCL injection in 4 cases, they were all confirmed dichorionic twin, and in 2 cases of monochorionic twin, we used alcohol ablation of intra-abdominal umbilical artery in 1 case, and radiofrequency ablation of the cord in 1 case. CONCLUSION: All procedures were successful, and all normal infants were delivered in 3rd trimester. Tailored selective termination in 2nd trimester is effective and safe in abnormal multifetal pregnancies.

OBJECTIVE: To compare the clinical results between laparoscopically assisted vaginal hysterectomy (LAVH) and total vaginal hysterectomy (TVH). METHODS: We reviewed the medical records of patients who underwent LAVH and TVH from January 2002 to December 2004 in 00 university hospital without the history of uterine prolapse or pelvic relaxation. We evaluated age, parity, previous abdominal operations, indication of hysterectomy, size of the uterus, operation time, hemoglobin change, hospital day, the degree of postoperative pain and initiation of diet and postoperative complications. RESULTS: The age and parity of the patients in both groups were not different statistically. There were history of previous abdominal operations in 20.8% of LAVH group and 25.3% of TVH group which didn't have statistic significance. Major indications of the operation were uterine myomas in both groups. The average weight of the extracted uterus were 272.9+/-114.5 gm and 225.6+/-87.0 gm in the LAVH group and the TVH group respectively which had significance, and the operation time were 81.1+/-23.4 minutes and 71.1+/-37.8 minutes respectively which had significance. There were no difference in the hemoglobin drop of the postoperative day 1, but the hemoglobin drop of the postoperative day 4 was larger in the LAVH group. Postoperative complications occurred more often in the TVH group (15.2%) than LAVH group (11.9%) but didn't have significance, and the complications were treated by conservative managements and observation of the progress. And also the hospital day, the degree of postoperative pain and initiation of diet had no significance. CONCLUSION: Both LAVH and TVH had no statistic difference in the postoperative morbidity and recuperation. Moreover the indications of operation for both surgeries had no statistic difference, but LAVH had a preference for the larger size of uterus. Furthermore in order to increase the satisfactions of patients and remedy the weak points of procedures, research on the indications and contra-indications between the operative approaches and training on the operative procedures are required.

OBJECTIVE: The aim of this study is to prove the clinical significance by evaluating pregnancy outcomes from intrauterine growth restriction using waves of the Doppler velocimetry of uterine and umbilical artery and amniotic fluid index. METHODS: Throughout the period of January 2000 to May 2005 at our hospital, we reviewed 127 cases diagnosed with intrauterine growth restriction after 24 weeks of pregnancy and the existences of diastolic notch of uterine artery (DNUT), absent or reversed end-diastolic velocity of umbilical artery (AEDV) and oligohydramnios were considered abnormal. We set the group that had no abnormal signs as the control group (62 cases), and respectively compared the groups that had oligohydramnios (24 cases), unilateral DNUT (27 cases), bilateral DNUT (10 cases) and AEDV (13 cases) with the control group. And we compared the groups that had only one abnormal sign, that is oligohydramnios (20 cases), bilateral DNUT (7 cases), AEDV (7 cases) and the group showing 2 or more complicated abnormal signs those above (9 cases) with the control group. RESULTS: Perinatal outcomes such as preterm birth, low birth weight, lower 5-min Apgar score (A/S), neonatal acidosis, admission rate of neonatal intensive care unit (NICU) and perinatal mortality were poor statistically in groups with DNUT, AEDV and oligohydramnios compared to those which have none of these abnormal signs. And those with DNUT had worse results when affected on both sides. And those with AEDV showed worse perinatal outcomes compared to those with bilateral DNUT or oligohydramnios; any overlapping of these abnormal signs indicated worse perinatal outcomes, which had statistic significance. CONCLUSION: Close observation of the fetal well-being by analysis on the wave velocimetry of the blood flow such as the uterine arteries and umbilical arteries and the measurement of the amniotic fluid volume enables predicting the perinatal prognosis of the intrauterine-growth restricted fetuses which may contribute in reducing the perinatal morbidity and mortality.

OBJECTIVE: To compare the clinical results for women undergoing total abdominal hysterectomy (TAH), laparoscopic assisted vaginal hysterectomy (LAVH) and total vaginal hysterectomy (TVH). METHODS: We reviewed the medical records of patients who underwent TAH (n=97), LAVH (n=112) and TVH (n=95) from June 2002 to June 2005. We compared and evaluated patient's characteristics, previous abdominal operation histories, indication of hysterectomy, uterine weight, operative time, perioperative hemoglobin and hematocrit change, the degree of postoperative pain, hospital stay and complications. RESULTS: The patient's characteristic (age, weight, height, parity, perioperative hemoglobin and hematocrit change, complication rate) had no statistical difference in all three groups. In the TVH group, the rate of previous abdominal operations (25%) was significantly lower than TAH (56%), and LAVH (40%) (p=0.023). The mean uterine weight was the heaviest in TAH group (443.6+/-407.3 g), compared to LAVH group (301.9+/-133.9 g) and TVH group (225.3+/-91.8 g) (p<0.001). Operative time was the longest for LAVH group (p=0.001), and there was no significant difference between TAH group and TVH group (p=0.087). The TAH group had the highest postoperative pain scale and the length of hospital stay. The LAVH group and TVH group had almost the same postoperative pain scale and the length of hospital stay. CONCLUSION: Both LAVH and TVH had the following advantages compared with total abdominal hysterectomy: less pain, shorter hospital stay, cosmetic advantages. But limited operation field in TVH and expensive operative cost in LAVH were disadvantages. Specific guidelines for determining the route of hysterectomy result in decreased morbidity and lower costs, and thus the gynecologist can ensure that the patient receives the best possible surgical care.

Peripartum cardiomyopathy is a dilated cardiomyopathy of unexplained cause that occurs during the last trimester of pregnancy or within 5 months after delivery. And, It is a rare disease that has a frequency of 1 in 1,300-15,000 deliveries. It has not yet been reported that peripartum cardiomyopathy has occurred in an preeclampsia woman superimposed on idiopathic thrombocytopenic purpura. Moreover, the association between idiopathic thrombocytopenic purpura and peripartum cardiomyopathy has not been studied. Recently, we experienced a case of a woman who has undergone emergency Cesarean section due to complicated severe preeclampsia superimposed on idiopathic thrombocytopenic purpura. On the postoperative day, this patient developed respiratory distress and pumonary edema. Peripartum cardiomyopathy was diagnosed by echocardiography and we present with a brief review of literatures.

OBJECTIVE: Comparative genomic hybridization (CGH) is a new fluorescence in situ hybridization (FISH) technique to identify genomic aberrations in cancers. The purpose of this study was to analyze non-random chromosomal DNA aberrations involved in cervical squamous cell carcinoma cell lines from Korean women. METHODS: We analyzed non-random chromosomal DNA aberrations involved in cervical squamous cell carcinoma cell lines from Korean women, SNU-17, SNU-682, and SNU-902 using CGH. RESULTS: Chromosomal DNA gains of 5p, 5q22-q23, 8q11.2-q12, 14q21-qter, and 20 as well as chromosomal DNA losses of 21 were found frequently. Chromosomal DNA gains on chromosome 3q, 6P, 7p13-pter, 9p22-pter, 9q21-qter, 15q21-q22, 17q22-qter, 18p11.3-pter, 18q11.2-q21, 19p13.3-pter, 19q13.2-q13.3, and 22q12-qter, with losses on 4p14-pter, 10p11.2-p13 and 10q24 were observed in 2 of 3 cell lines. CONCLUSION: Non-random aberrations which were disclosed in this study might be candidate regions for the abnormal genes involved in the tumorigenesis of cervical squamous cell carcinomas. Datas about chromosomal aberrations of Korean squamous cell carcinoma cell lines in this study could afford very useful basic information for the development of diagnostic and therapeutic modalties targeting the abnormal genes associated with uterine cervical cancer in Korea.

Placenta accreta is a rare condition and is associated with considerable maternal morbidity and mortality. Though hysterectomy is a definitive therapy, there are some occasions that conservation of the uterus is desired by the patient and bleeding is not excessive. We report a case successfully treated using methotrexate in patient whose placenta was not detached from the uterus with a brief review of literature.

OBJECTIVE: We have attempted to identify prognostic factors regarding CC/hMG ovarian stimulation and IUI in infertility and to seek factors valuable in planning infertility treatment and predicting the success rate of IUI therapy in individual couples. METHODS: The variables selected for initial analysis were female age, duration of infertility, type and diagnosis of infertility, number of pre-ovulatory follicles (>or=16 mm, >or=18 mm follicles), thickness of the endometrium, number of the treatment cycles, result of semen analysis, ovarian stimulation protocol, number of IUI. A logistic regression method was used to identify significant variables that contribute to the success of CC/hMG/IUI treatment. RESULTS: Logistic regression analysis revealed four predictive variables as regards pregnancy: duration of infertility (p=0.011), infertility etiology (p=0.049), number of IUI (p=0.004), method of ovarian stimulation (p=0.042). A cause of infertility, especially ovarian dysfunction other than tubal factor, a shorter duration of infertility (<6 years) and CC/hMG minimal ovarian stimulation protocol with double IUI resulted in better treatment success in CC/hMG with IUI cycles. CONCLUSION: We concluded that careful patient selection criteria coupled with successful ovarian stimulation and increased sperm count in female reproductive tract is the model for CC/hMG/IUI sucess.

Persistent cloaca is a very rare congenital anomaly with a single common perineal opening for the genital urinary and gastrointestinal tract, which is caused by abnormal formation of the urorectal septum. It has an incidence of 1 in 50,000 to 1 in 125,000 births and is much more common in females and in twin pregnancies. Pathologic findings of persistent cloaca include dilated bowel, hydrocolpos, urethral obstruction, hydronephrosis and oligohydramnios caused by obstruction of the bladder, vagina and intestine. Failure of the paired m llerian ducts to fuse also usually results in duplication of the uterus and vagina. Currently, the diagnosis depends on the prenatal sonography but the diagnosis may be very difficult due to the complex nature of the anomaly and variable appearances. We present a case of persistent cloaca with one opening confirmed by autopsy after therapeutic termination which was initially diagnosed by prenatal sonography.

OBJECTIVE: To compare the perinatal outcomes in twin and singletone pregnancies delivered prematurely between 28 and 36 weeks gestational age. METHODS: We studied 80 pairs of twin delivered between 28 weeks and 36 weeks gestational age at Eulji university hospital between January 1996 and October 2000. The perinatal morbidity and mortality in premature twin pregnancies were compared to those of premature singleton pregnancies (N=402). RESULTS: The premature twin pregnancies had no significant differences of gestational age at delivery than those of singleton pregnancies, but significantly lower mean birth weight. In mean day of hospital stay, 1 and 5 min Apgar scores, there were no significant differences. There were no significant differences in the incidence of neonatal morbidity such as hyaline membrane disease, and retinopathy of prematurity, between the two groups. And also the perinatal mortality was not significantly different between the two groups. CONCLUSION: There were no significant differences in perinatal mortality and morbidity between the two groups.

OBJECTIVE: To evaluate pattern of associated structural anomalies, abnormal karyotypes and perinatal outcomes of fetuses with prenatally diagnosed single umbilical artery and to evaluate the relation of absent side of a single umbilical artery in association with anomalies and abnormal karyotypes. MATERIALS AND METHODS: 30 fetuses with a single umbilical artery were detected by prenatal ultrasound examnination between March 1998 and June 2001 at Eul-Ji University Hospital. All medical records were reviewed for maternal demographics, associated anomalies, karyotypic analysis, pregnancy complications, and neonatal outcome. RESULTS: Of the 30 fetuses, 11 (36.7%) were terminated because of severe anomalies and 2 (6.7%) experienced neonatal death. 17 fetuses (56.7%) had an associated structural anomaly. The structural anomalies found in association with single umbilical artery were cardiovascularac system (9 cases, 30.0%), urogenital system (6 cases, 20.0%), central nervous system (5 case, 16.7%) and ectopia cordis (1 case, 5.9%) and 7 cases (20%) among these had multiple malformations. Karyotype analysis was availabe in 25 cases and 5 (20%) of these were chromosomally abnormal. All of the karyotypically abnormal fetuses had a structural defect diagnosed on prenatal ultrasound examination in addition to the single umbilical artery. Of 13 fetuses without any associated structural or chromosomal anomalies, 3 (23.1%) demonstrated growth restriction. Of the 26 cases identified the absent side of a single umbilical artery, the right umbilical artery was absent in 13 (50%) and the left in 13 (50%) fetuses. The frequency with associated structural and chromosomal anomalies was equal on right (53.8%; 15.4%) and left (69.2%; 15.4%) sides. CONCLUSION: Scanning the umbilical cord should be one of the essential parts of 2 nd trimester ultrasonographic examination. When single umbilical artery is detected, a detailed ultrasonographic examnination including fetal echocardiography and fetal karyotyping should be recommended for search of associated structural and chromosomal abnormalities. In cases where single umbilical artery is an isolated finding on prenatal ultrasound, careful attention to fetal growth is necessary.
