Factors associated with a positive intake of folic acid in the periconceptional period among Korean women

OBJECTIVE We aimed to investigate the factors associated with a positive intake of folic acid (FA) during the periconceptional period among Korean women. DESIGN In a cross-sectional study of demographic, obstetric and socio-economic data, history of periconceptional intake of FA and awareness of the benefits of FA supplementation in pregnancy were obtained and analysed using the chi2 test, followed by multiple logistic regression analysis. SETTING The Maternity School, Cheil General Hospital and Womens Healthcare Center, Seoul, South Korea, between October 2005 and March 2006. SUBJECTS In total 1313 pregnant women participating in a two-day training course available every month. RESULTS After excluding subjects with incomplete or inconsistent data, there were 1277 women included in the analysis. Participants were aged 29.4 (sd 2.9) years and had a mean gestational age of 27.9 (sd 7.1) weeks. Only 131 (10.3 %) women took FA during the periconceptional period. According to multiple logistic regression analyses, the adjusted OR for FA supplementation was 1.79 (95 % CI 1.10, 2.91) in women who had previous spontaneous abortions, 4.10 (95 % CI 2.43, 6.78) in women who planned their pregnancy and 6.63 (95 % CI 2.08, 21.12) in those who were aware of the protective effects of FA. CONCLUSIONS Periconceptional intake of FA was more likely among Korean women with a history of previous spontaneous abortion, who planned their pregnancy or who were aware of the protective effects of FA during pregnancy. However, the proportion of women who took FA in the periconceptional period was low.

P02.68: Various prenatal sonographic findings of normal and abnormal fetal genitalia

regression of the lesion. As it regards the other 9 cases, 4 cases with cyst diameter less than 5cm were aspirated in utero. Progressive decrease in size and subsequent prenatal or postnatal regression was observed. The remaining 5 cases were submitted to postnatal operative laparoscopy. 1 case among those treated in utero underwent premature rupture of membranes and 1 case showed preterm labor. Conclusion: Many complications associated with fetal and neonatal ovarian cysts have been reported, including gastrointestinal obstruction or perforation, ascites, polyhydramnios, cyst rupture, hemorrhage and torsion. Nevertheless, in utero procedures, make the patients at risk of rupture of membranes, bleeding, intrauterine infection and premature labor. Criteria for management are still debated. A controversial about conservative versus surgical therapy remains. Therapeutic approach should be personalized in order to considered gestational age, size of the cyst, the presence of complications. These considerations will be extensively discussed.

P04.20: Pre & postnatal imaging findings of fetal neoplasms

by conventional 2D ultrasound, it was confirmed by another senior sonographer. 3D color and power Doppler were applied to delineate vascular anatomy of this area subsequently. Confirmation of antenatal diagnosis was made in all newborns. Results: Four fetuses with PRUV were detected in these 1067 cases. The estimate incidence is about 0.375% (1 : 267). Ductus venosus were found in all of the fetuses. All of them had no other additional malformation. Discussion: The diagnosis of persistent right umbilical vein was easily made in a transverse section of the fetal abdomen with ultrasound findings of the portal vein towards to the stomach and fetal gallbladder located medially to the umbilical vein by twodimensional sonography. The incidence of PRUV in our patients was similar to other articles. Reconstruction of portal system in fetus with PRUV by 3-dimensional ultrasound was easy to delineate the vascular anatomy of this area. We proposed this modality can be used to help to understand the vascular anatomy of the fetus with PRUV.

OC24.07: Usefulness of measurement of the fetal thymus in the diagnosis of IUGR: a preliminary result

Comment: In CHD fetuses, increased DV Index, associated with reduced forward ductal flow to the right atrium, well correlates with increased right atrial pressure occurring in right outflow tract obstruction or in hypoplastic left ventricle. On the contrary in IUGR fetuses with increased DV Index and compensatory ductal dilatation, normal left cardiac output suggests normal myocardial function due to a maintained or even increased forward flow through the DV to right atrium.

P04.30: Ultrasound findings of venous anomalies in the fetal liver

(20%) postnatally diagnosed and in 13 (7%) cases the timing of diagnosis was unavailable. In 13/128 cases reported antenatally the fetus/baby did not have unilateral CDH or had been misdiagnosed. The majority of affected pregnancies were singleton (98%). Of the antenatal suspected/diagnosed cases there were 70 babies delivered alive (39 died subsequently), 4 miscarried, 8 were stillbirths, 43 had termination of pregnancy (TOP) and in 1 case this information is missing. Most cases (68%) were diagnosed between 18–23 weeks. All TOP’s were performed at less than 24 weeks gestation and 28/43 (65%) fetuses had other associated structural anomalies/chromosomal problems. Conclusions: The prevalence of CDH was 3.5 per 10 000 births in this region. 27% of pregnancies diagnosed with unilateral CDH antenatally resulted in a live born infant that survived the immediate postnatal period. Majority of the cases reported to the register were diagnosed antenatally. Increased surveillance for other anomalies is required when CDH is suspected/diagnosed antenatally. Population based data should be used in counselling parents.

P075: Prenatal sonographic diagnosis of omphalocele: the significance of the omphalocele contents

Objective: This study was undertaken to evaluate the feasibility of using free-hand three-dimensional (3D) ultrasonography to evaluate the volume of the fetal stomach. Material and methods: We studied a total of 108 normal singleton fetuses from 13 to 42 gestational weeks. During 2D ultrasonographic examination three-dimensional upper abdomen data were collected prospectively. The stomach was scanned with a fanning motion of the transducer in the axial plane, nearly parallel to the conventional abdominal circumference plane. 3D volume segmentation processing of the stomach was performed and saved in different files. Stomach volume was calculated. Results: In almost all cases in which the stomach was visualized it was possible to calculate structure volume. There was considerable volume variation during the range of gestational ages studied. This preliminary study would have to be expanded to construct nomograms of stomach dimensions. Conclusion: 3D echocardiography can provide estimates of fluid filled fetal organs’ volumes and can be used for nomogram construction.
