ABSTRACT
The aim of this study was to assess the effectiveness of active intervention with antenatal maternal corticosteroid and antibiotics therapy in infants delivered between 24 and 28 weeks of gestation after premature rupture of membrane. This retrospective study included pregnant women complicated by preterm delivery at the Dong-A University Hospital from 1998 to 2002. Patients were divided into labor induction group 1 (n=20), observation group 2 (n=19), and medication group 3 (n=20). We evaluated the effects of prolongation of pregnancy and intervention with maternal corticosteroids and antibiotics therapy on perinatal and neonatal outcomes. Each group did not have a significant difference (p<0.05) in neonatal outcomes, such as respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, retinopathy of prematurity, pneumonia, bronchopulmonary dysplasia, and sepsis. The mean latency period was 4.7 days and 7.6 days in groups 2 and 3, respectively. Therefore, this study was unable to demonstrate any beneficial effects of corticosteroids in improving neonatal outcomes and prolongation of the latency period with antibiotics.

OBJECTIVE: To understand the pathogenesis of adenomyosis through the immunohistochemical staining with bcl-2 and matrix metalloproteinase-9 (MMP-9) antibody. METHODS: We selected 45 cases of adenomyosis among the uterine specimens that were extirpated surgically due to benign gynecologic problem. Immunohistochemical staining to the myometrial tissue was performed using anti-bcl-2 and anti-MMP-9 antibodies. Staining was qualitatively assessed in terms of extent and intensity. RESULTS: There were 32 cases of proliferative phase and 13 cases of secretory phase depending on the date of endometrium. Anti-bcl-2 stained 81.3% (26/32) compared with anti-MMP-9 stained 6.3% (2/32) in the glandular tissue of the proliferative phase (p<.001). In the secretory phase, anti-bcl-2 92.3% (12/13) and anti- MMP-9 7.7% (1/13) respectively (p<.001). In the stromal tissue of the proliferative phase, anti-bcl-2 stained 62.5% (20/32) compared with anti- MMP-9 stained 6.3% (2/32) (p<.001). In the secetory phase, anti-bcl-2 84.6% (11/13) and anti-MMP-9 15.4% (2/13) (p<.001). CONCLUSION: The adenomyosis may be developed from simple invagination and cellular proliferation of endometrial tissue, not caused by myometrial infiltration of endometrial tissue.

OBJECTIVE: Amniocentesis is the most commonly used invasive method for prenatal diagnosis of genetic disorders. We performed this study to analyze the indications, distributions of maternal age and cytogenetic results of midtrimester amniocentesis. METHODS: We retrospectively analyzed 785 cases of midtrimester prenatal genetic amniocentesis which were performed in the cytogenetics laboratory using in situ coverslip culture at Dong-A University Hospital from January 1995 to March 2003. RESULTS: Amniocentesis was practiced mostly from 15 weeks to 20 weeks of gestational ages. Requested indications of amniocentesis were abnormal maternal serum screening (421, 53.7%), advanced maternal age (233, 29.7%) and abnormal ultrasonographic finding (61, 7.8%) in the order of decrease. The overall incidence of chromosome abnormalities was 5.1% (40 cases), and it contains 27 cases (3.4%) of numerical abnormalities and 13 cases (1.7%) of structural abnormalities. Among autosomal abnormalities Down syndrome was most common (13 cases) and followed by Edward syndrome (2 cases). Of the sex chromosomal abnormalities, three cases of Turner syndrome and three cases of Kleinefelter syndrome were found. Chromosomal abnormalities were most frequently noted in the maternal age of 30 to 34 years old (14 cases, 35.0%), 25 to 29 years old (12 cases, 30.0%), followed by 35 to 39 years old (7 cases, 17.5%). The frequency of pseudomosaicism were 5 cases (0.6%). CONCLUSION: Maternal serum screening, advanced maternal age and antenatal ultrasonographic finding must be important screening methods for amniocentesis which is considered to the most effective diagnostic procecdure for prenatal cytogenetic studies. I conclude that the karyotyping analysis of midtrimester amniocentesis is efficacious method for detection of chromosomal aberration and genetic counselling for parents.

Twin-to-twin transfusion syndrome (TTTS) is one of the complications showing high mortality rate in monochorionic twins with vascular communication in the placenta. Clinical manifestations of TTTS are usually characterized by polyhydramnios, circulatory overload, cardiac failure and fetal hydrops in the recipient twin and symmetrical fetal growth restriction, oligohydramnios, hypovolemia and anemia in the donor twin. TTTS occurres in 10-35% of monochorionic twins. We report three cases of TTTS with fetal hydrops in which amnioreduction was serially attempted and maternal digoxin treatment was tried for the therapeutic purpose.

OBJECTIVE: During early pregnancy, CD71 and glycophorin A positive cells in peripheral blood of pregnant women were studied, to assess the relationship between increased numbers of nucleated RBC (NRBC) in maternal blood and pregnant outcomes. METHODS: Peripheral venous blood samples were obtained from 47 primigravidas of 14~16 weeks gestation. Triple screening tests were routinely performed. Blood samples were incubated with monoclonal anti-CD71 and monoclonal anti-glycophorin antibodies, and analyzed by flow cytometry using FACSort (Becton Dickinson, USA) for checking the NRBC count. RESULTS: A total of 47 pregnant women were enrolled at 14-16 weeks gestation; one pregnancy had anemia and was excluded from the test, the outcome was unknown for 2 other pregnancies, and twelve pregnancies had 1-4% of NRBC in the maternal blood. In the remaining 32 pregnant women, grouped according to their percentage of NRBC, the group with more than 4% of NRBC was termed the study group, and less than 1% of NRBC was termed the control group.The results were as follows: 1) The study group showed lower fetal birth weight than the control group, which was statistically negatively significant (y=-62.219x + 3,401.6, R2=0.2146, p0.05).3) There were two complications in the study group: one was a preterm delivery at 35 weeks of gestational age with birth weight of 2,300 gm and the other was a case of pregnancy-induced hypertension. CONCLUSION: It can be concluded that increased NRBC count in maternal blood during the early second trimester has a significant correlation with fetal birth weight but can't predict high risk pregnancies such as preeclampsia, preterm labor or intrauterine fetal growth restriction.In order to obtain a higher predictive value, further studies with more participants and with high risk pregnancies of known risk factors are needed.

Abnormal offsprings from balanced translocation carriers usually inherit only one of the translocated products and are therefore partially trisomic for one chromosome and partially monosomic for another. Partial trisomy 1q usually demonstrates fetal growth restriction and anomalies of head, face, urogenital tract, heart, finger and toes with a wide range of characteristics and severities. It has been reported in a few individuals in the world and this is the first report of partial trisomy 1q in Korea. We present the case of recurrent partial trisomy 1q in maternal balanced translocation which was prenatally diagnosed by amniocentesis with fluorescence in situ hybridization(FISH) based on abnormal ultrasonographic findings and poor obstetric history.

Plasmapheresis has been used for some conditions during pregnancy and puerperium, such as hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. We present one case of the HELLP syndrome which was treated with plasmapheresis and also review the indications, complications and guidelines for repetitive plasma exchange.
