A Study of the Rubella Antibody in Korean Fertile Women in the Last 5 Years (1992~1996) / 대한산부인과학회잡지

In the past two decades, the incidence of rubella infection has decreased due to a nation-wide rubella vaccination program. Therefore the rate of rubella Ig G antibody has decreased. This means an increasing vulnerability to rubella infection among the group, with negative Ig G antibodies. The study was conducted in January of 1992 to April of 1996. The subjects were 1,010 fertile women(ages 20/45 years). The study was performed at Park Women`s Clinic to investigate the status of rubella antibody in Korean fertile women. The results were as follows. 1. The positive rate of rubella Ig G and Ig M antibody were 80.5% and 1.5%, respectively. 2. The mean age of positive rubella Ig G group was 28.5+/-3.6 years. The positive rate of rubella Ig G antibody was decreased by an increase in age with a significant level at p < 0.05. 3. The positive rate of rubella Ig G antibody was 63.3% in 1992, 71.3% in 1993, 87.5% in 1994, 81.1% in 1995 and 83.8% in 1996. The increase in the positive rate of rubella Ig G antibody by year for 5 years was statistically significant at p < 0.05. 4. The positive rubella Ig M antibody was noted in 15 women. Among them, one woman was tested in 1993, 5 women in 1995 and 9 women in 1996. The incidence of rubella infection had increased by years, and was statistically significant at p < 0.05. 5. The mean titer of rubella Ig G antibody was 47.18+/-50.04 IU/ml. The titer of rubella Ig G antibody was decreased by the increased in at age(p < 0.05). We observed a low positive rate of rubella Ig G antibody as compaired with other studies that were performed before 1990. Therefore, to prevent sporadic rubella infections, rubella vaccinations should be given to unmarried women.

Transvaginal Color Doppler Imaging in the Assessment of Utero-placental Blood Flow in Normal and Abnormal Early Pregnany / 대한산부인과학회잡지

Flow velocimetry waveforms of the uterine artery and subtrophoblastic blood flow were analyzed at normal early pregnancy, missed abortion and blighted ovum, by using transvaginal color Doppler ultrasonography. Results show that a progressive fall in S/D ratio and RI with advancing in gestation. Among the three groups, the S/D ratio and RI of both uterine arteries were not a significant difference in all gestational age. Characteristic subtrophoblastic blood flows were obtained in 60.3%, 47.2% and 53.3% of normal pregnancy, missed abortion and blighted ovum, respectively. The S/D ratio and RI of subtrophoblastic blood flow were not a significant difference among the three groups. Although the number of cases studied is small and not prospective study, the further study about this will give us some understanding to the pathophysiology of early pregnancy failure.

The utilization of Doppler ultrasonography with color flow mapping in the diagnosis and evaluation of malignant trophoblastic tumors

The Doppler ultrasound with color flow mapping image has been recently applied for the evaluation of gynecologic diseases, in particular, malignant trophoblastic tumors with the characteristic abundant blood flow. Doppler color flow mapping of uterine artery and intratumoral blood vessels was performed at a regular interval in all 26 patients including 3 cases of lost for follow up. Systolic/diastolic (S/D) ratio representing blood flow was measured in 19 cases of malignant trophoblastic tumors and 7 cases of hydatidiform mole diagnosed at the department of Obstetrics and Gynecology, Yonsei University, College of Medicine. The initial mean S/D ratio and standard deviation(SD) of uterine artery in 11 remitted and 5 non-remitted patients were 2.72 +/- 1.31 and 2.69 +/- 1.80, respectively. No significant difference was noted between two groups. However, the final S/D ratio of uterine artery in remitted group showed significantly higher values than non-remitted group, of which values were 6.23 +/- 2.38 and 3.08 +/- 1.54, respectively (p< 0.05). In aspect of blood flow changes in malignant trophoblastic tumors after chemotherapy, remitted group showed entirely disappeared blood flow, while non-remitted group had persistent blood flow. The mean S/D ratio and SD measured in hydatidiform mole patients were 5.43 +/- 1.65, of which value reflects higher resistance than malignant trophoblastic tumors. Also blood flow was not detected in all cases. This study suggests that color flow mapping Doppler ultrasound can be a useful method in diagnosing and monitoring the treatment in malignant trophoblastic tumors along with the conventional serum beta-hCG titration.
