Obstetrical outcome after oocyte donation in patients with premature ovarian failure / 대한산부인과학회지

OBJECTIVE: The purposes of this study are to evaluate the obstetric outcome in pregnancies resulting from oocyte donation and to assess the factors related to the obstetric complications. METHODS: The obstetric outcome in pregnancies from the oocyte donation (n=37) was compared with that in pregnancies from conventional IVF program (n=137) in our IVF center between January 1995 and December 2000. Control group was selected by age, parity, and order of gestation matched to the study group. Pregnancy induced hypertension (PIH) was defined as blood pressure >140/90 mmHg on two or more occasions at least 6 hours apart with or without proteinuria after 20 weeks of gestation and not associated with chronic hypertension. Small for gestational age (SGA) was defined as birth weight below tenth percentile for gestational weeks. The data was analyzed using the Statistical Package for Social Sciences (SPSS). RESULTS: Early pregnancy loss rates were 37.8% (14/37) and 23.4% (32/137) in study and control group, respectively (P>0.05). PIH related factors such as mean age, parity and order of gestation were not significantly different among the two groups. However, the incidence of PIH in oocyte donation group (30.0%, 6/20) was significantly higher than control group (8.8%,9/102). There was no significant difference in the incidence of SGA between the two groups. When oocyte donation group was stratified by relationship of oocyte donor to infertile patient (sibling versus non-sibling), the incidence of early pregnancy loss and PIH was significantly higher (chi square test, P<0.05) in non-sibling group (42.3%, 11/26; 38.5%, 5/13) than in control group (23.4%, 32/137; 8.8%, 9/102). CONCLUSION: The incidence of PIH was significantly higher in pregnancies after oocyte donation. Notably, the pregnancies from non-sibling oocyte donors had much higher incidence of early pregnancy loss and PIH than pregnancies from sibling oocyte donors or control group. Therefore, the occurrence of early pregnancy loss and PIH may be related to other factors than age, parity or multiple pregnancy.

Frequency of fetal anomaly and perinatal outcome in polyhydramnios / 대한산부인과학회잡지

OBJECTIVE: To determine the frequency of fetal anomaly and perinatal outcome in pregnant women with polyhydramnios. METHODS: Ultrasound examinations from January 1998 to August 2001 were reviewed to identify 170 patients with singleton pregnancy which diagnosed polyhydramnios. Frequency of fetal anomaly and perinatal outcomes were compared with amniotic fluid index (AFI) 20.0-25.0 cm as group 1 and AFI >25.0 cm as group 2. RESULTS: The prevalence of polyhydramnios was 0.54% (170/31,358). The types of structural anomalies were gastrointestinal system (10/34, 29.4%), genitourinary system (9/34, 26.5%), central nervous system (CNS, 6/34, 17.7%), cardiovascular system (CVS, 3/34, 8.8%), neuromuscular system (2/34, 5.9%), respiratory system (1/34, 2.9%) and others (3/34, 8.8%). The structural anomaies between two groups were significantly different. The rate of cesarean section, low 5-min Apgar score (25.0 cm) and genitourinary system anomaly was dominant in group 1 (AFI 20.0-25.0 cm). Polyhydramnios (AFI>25.0 cm) indicated an increased risk of severe fetal anomaly.

Surgical Management of Adnexal Mass during Pregnancy / 대한산부인과학회잡지

OBJECTIVE: The objective of this study was to evaluate the safety and timing of the surgery and fetal outcome of pregnancy complicated by a persistent adnexal mass that was required surgical intervention METHODS: We retrospectively reviewed 171 cases of adnexal masses during pregnancy that were required surgery at Samsung Cheil Hospital and Women's Healthcare Center between 1996 to 2001. We analysed medical records for characteristics of tumor, indication and timing of surgery and the effect of pregnancy outcome. Adverse pregnancy outcome is defined as preterm delivery, spontaneous abortion, intrauterine fetal death and perinatal death. The obtained data were analysed using t-test and Fisher's exact test by SPSS. RESULTS: The incidence of adnexal masses during pregnancy that required surgical management was 1 in 292.3 live births. A malignant tumor or a tumor of low malignant potential was found in 7% of cases. A total of 43 patients underwent surgery under emergency condition, 31 (72%) of which were done due to torsion. There were 14 preterm delivery, 3 spontaneous abortion, 1 intrauterine fetal death, 1 perinatal death and 2 artificial abortion in this study. There was a significant difference in adverse pregnancy outcome between elective and emergency group (7/118 [5.9%] versus 11/43 [25.6%] P=.001), and surgery group that before 20 week's gestation and those of after 20 week's gestation (12/145 [8.3%] versus 6/16 [37.5%] P=.004). CONCLUSION: When necessary and feasible, surgery should be scheduled for the early portion of the second trimester, when organogenesis is complete and most spontaneous abortion have occurred, but before later risks of technical difficulties and premature labor. Also we recommend early diagnostic evaluation and immediate surgical intervention of adnexal masses as problematic adnexal mass diagnosed during pregnancy to prevent the risk of emergency surgery associated with adnexal complication (torsion, rupture and hemorrhage) and the risk of delayed diagnosis of malignancy.

Chromosome Analysis of Abortuses in Recurrent Spontaneous Aborters with Serum Anticardiolipin Antibodies / 대한산부인과학회잡지

OBJECTIVE: It has been suggestes that various mechanism of fetal loss are associated with anticardiolipin(ACA) and humoral immunity in the patients with recurrent spontaneous abortion. Thus we have investigated the relationship between ACA and chromosomal anomaly to know the clinical impact of ACA to early fetal loss as comparing to the chromosomal anomaly in the patients of recurrent spontaneous abortions. MATERIALS AND METHODS: Patients(n=88) with a history of recurrent spontaneous abortion (2 or more) between January 1, 1994 and June 30, 1999 were included in this study. Quantitative measurement of serum ACA was performed by ELISA and chromosomal analysis of chorionic villi obtained from aborted conceptuses was done by using standard G-banding technique. RESULTS: The incidence rate of ACA positive was 27%(24/88) and that of chromosomal abnormality was 57%(50/88). The incidence rate of abnormal karyotype was 54% (13/24) in ACA positive. Among 24 ACA positive, 10 had IgG-ACA positive, 10 had IgM-ACA positive and 4 had both types of ACA. The incidence rate of chromosomal anomalies was 30% (3/10) in IgG-ACA positive, 90%(9/10) in IgM-ACA positive and there was significant difference between these two groups (p=0.02). The incidence rate of chromosomal trisomy was 59% (23/37) in ACA negative, 62% (8/13) in ACA positive and there was no significance between two groups. CONCLUSIONS: The significantly low incidence of chromosomal abnormalities in conceptal products of patients with IgG-ACA comparing that of patients with IgM-ACA suggests that this isotype of antibody have influence on the genesis of spontaneous abortions in genetically normal pregnancy. In further studies, additional trials are mandatory for obtaining a definitive conclusions about relationship between pathologic changes of conceptal products and pathophysiologic effects of IgG-ACA.
