[en] Edwards syndrome is the second most common trisomy syndrome occurring in 0.3/1,000 births. The prenatal diagnosis of this trisomy may be suspected in the routine ultrasound exam of the pregnancy by means of the recognition of a constellation of findings: fetal structural anomalies, intrauterine growth retardation (CIR) and umbilical cord or amniotic fluid volume abnormalities. The diagnosis is then confirmed by chromosome analysis of either amniotic fluid or fetal blood or tissue. We present six cases of Edwards syndrome suspected by fetal ultrasonography exam, all of them confirmed by karyotype, describing the major sonographic findings. (Author) 15 refs

[en] To evaluate the sonographic features and appearance time of the physiologic midgut herniation early in pregnancy. Sonograms of 87 features ranging from 7 to 13 weeks were obtained over a 2-month period. The presence or absence, the size and echogenecity of the physiologic midgut herniation were evaluate on each examination. Disappearance of the midgut herniation was confirmed on follow-up sonogram at 13-20 weeks, 3-12 weeks after the first sonogram. The results were analyzed in terms of appearance or disappearance time of midgut herniation. In all cases of physiologic midgut herination, an echogenic mass measuring 0.4-0.7 cm wa demonstrated within the base of the umbilical cord at its insertion into the fetal abdomen. This herniation was detected in 3/6 cases (50%) at 8 weeks, in 15/16 cases (94%) at 9 weeks, in 22/24 cases (92%) at 10 weeks and in 12/27 cases (44%) at 11 weeks gestation. None of the features studied at 7 weeks and 12 weeks had a midgut herniation. Sonographic findings of a 0.4-0.7 cm sized echogenic mass within the base of the umbilical cord which appears from 8 weeks to 12 weeks pregnancy represent physiologic midgut herniation in early pregnancy and should not be confused with pathologic ventral wall defected such as omphalocele or gastroschisis.

[en] The aim of the present article is to provide an important example for the application of relative topology in biology. The model presented allows one to trace development of an embryo from zygote until birth by using basic concepts in topology, namely relative subspaces, together with dynamical topology and folding. This leads to insight into the stage at which medication should be used to stop any abnormality during pregnancy.

[en] Sonographic determination of fetal gender was attempted prospectively in most pregnancies of more than 26 weeks. We studied 193 cases of pregnancies with ultrasound for recent 9 months from June 1984 to February 1985 at department of radiology, Soonchunhyang university, Soonchunhyang Chunan hospital, and analysed ultrasonographic finding of fetal gender. The results were as follows; 1. Overall accuracy rate for fetal gender is 90%. 2. Accuracy rate for male fetus is 97.8%. 3. Accuracy rate for female fetus is 88.2%

[en] We report here a review of the current medical literature on pregnancy associated desmoids, including 10 cases of our own. The pertinent findings are that a large percentage of desmoids in females arise in and around pregnancy. Most occur in the abdominal muscles, particularly the right rectus abdominus, perhaps related to trauma from abdominal stretching and fetal movement. While these tumors may regress spontaneously after delivery most can be surgically resected with low recurrence rates even with R1 resections and this is clearly the treatment of choice. Subsequent pregnancies do not appear to result in recurrence in either FAP or non FAP patients. It is not clear from currently available data whether pregnancy associated desmoids are molecularly distinct from other desmoids

[en] Ultrasonography is playing an very important in diagnosis of normal pregnancy and the other diseases in the fields of obstetrics and gynecology. It is mainly used B-mode and Real time linear scan for pregnancy such as fetal movement during its early stage, fetal position, placenta location and biparietal diameter during its middle stage, and amniotic fluid and placenta previa during its late stage, as well as tumor accompanying pregnancy. Ultrasonography has been extensively used in the fields of obstetrics and gynecology for obtaining detailed images of soft tissues without hazard to the fetus and pregnant woman. In view of the need for its professionalism of high degree of skill, this treatise will introduce clinical instances and images obtained in the sonography room of the Seoul National University Hospital

[en] Objectives: To compare the efficacy, safety and cost effectiveness of Manual Vacuum Aspiration (MVA) with dilatation and curettage (DNC) in the management of early pregnancy failure. Methods: One hundred patients of spontaneous abortion, incomplete or missed, with gestational age <12 weeks were included in the study. Using a Random Number Table, these patients were assigned to undergo either DNC or MVA. Results: The distribution of age, parity and gestational age was similar in both groups. The mean duration of procedure was significantly higher (p<0.0001) in DNC (8.98+-2.64 minutes) as compared to 5.88+-2.43 minutes in MVA. The duration of hospital stay was significantly lower (p<0.0001) in MVA group (3.48+-1.2 hours) as compared to 7.42+-1.93 minutes in DNC group. Similarly the cost of procedure was also significantly lower (p=0.0001) in MVA group (PKR 1410+-243.4) compared to PKR 3460+-908.24 in DNC group. Conclusion: MVA is as effective as conventional dilatation and curettage for treatment of early pregnancy failure while it causes less blood loss, is less time consuming, requires a shorter hospital stay and thus costs less. It does not require general anaesthesia and complication rate is less than dilatation and curettage. (author)
