OBJECTIVE: The purpose of this study was to evaluate the clinical course of discordant fetal growth and perinatal outcome in relation to dichorionic and monochorionic twin for different degrees of birth weight difference. METHODS: Between Jan. 1992 and Dec, 1997, 154 twin pairs were born at Yonsei medical center and there were 36 pairs of twins which had 20% or more birth weight difference. The placental examination were performed routinely on all multiple births and 13 pairs of dichorionic twins and 23 pairs of monochorionic twins were consisted of the study population. These twin pairs were divided into three groups based on birth weight difference: 20-29%(as group A), 30-39%(as group B), and 40% or more(as group C). Gestational age, birth weight, gender and perinatal outcomes were observed for each twin pairs. RESULTS: The perinatal death in the monochorionic twin pairs showed 9(34.6%) as group A, 4(50%) as group B, and 5(41,7%) as group C and in the dichorionic twin paus 1(10.0%) as youp A, 0 as group B and 5(62.5%) as group C. Up to 40% of birth weight difference, dichorionic twin pairs showed good perinatal outcomes compared with monochorionic twin pairs but over 40% or more of birth weight diffaence, however there were no significant difference of perinatal outcomes by chorionicity. In the monochorionic twin pairs, the cause of perinatal death showed 3 cases of prematurity, 2 cases of congenital anomalies and 2 cases of IIOC and 2 cases of cord lesions in group A whenas in the group B and C 3 cases of prematurity and 6 cases of congenital anomalies. In the dichorionic twin pairs, different-sex twin pairs showed no perinatal death in all three groups but in same-sex twin pairs there were 6 perinatal deaths. CONCLUSION: More recent improved fetal ultrasonographic surveillance such as determination of chorionicity, identification of fetal sex and evaluation of fetal anomalies help to make a clinical decision in growth discordant twin up to 40% of weight difference each other.

It is well established that the CT is an essential part not only in screening primary brain tumors, but alsoin staging known malignancy. This paper reports various CT findings demonstrated in 12 cases of choriocarciomawith brain metastasis. The CT findings such as the number, location and density of the metastatic lesions, thedegree of brain edema, mass effect and effect of contrast enhancement are reviewed as well as the episode ofstroke syndrome and survival duration after neurologic symptoms attacks. The results were as follows; 1. Ten ofthese cases showed solitary metastatic lesion and remaining 2 cases were multiple lesions. 2. One was isodensedensity and the others were hemorrhagic increased denstiy by CT. 3. All of these showed mass effect to thesurrounding structures along with moderate to marked brain edema. 4. The position of the metastatic lesion werelocated at the supratentorially in all cases. Most of them were at the unilateral frontal or parietal area of bothof them. One which noted multiple metastatic foci showed at the bilateral occipital regions. 5. Nine cases showedring enhancement after contrast infusion. One which noted isodense density on the noninfusion scan showed alsoring enhancement after contrast infusion. 6. Nine cases showed positive stroke syndrom. One of them was perforemdemergency craniotomy. The remainging 3 cases noted progressive neurologic symptoms. 7. Two cases were noted onlybrain metastasis but the others also had various degree of pulmonary metastasis and 2 of latter had hepaticmetastasis, too. 8. Most of the cases were treated with CHAMOCA regimen, and one of them was taken whole brainirradiation (3000 rads/2 weeks). Another one case revealed marked regression of not only metastatic brain lesionbut the pulmonary lesion after the 8th course of CHAMOCA regimen and still alive for over 460 days.

OBJECTIVE: The aims of this study was to examine whether epileptic women with antiepileptic drugs(AEDs) treatment during pregnancy were associated with an increased risk of adversed pregnancy outcome. METHODS: The study design was a retrospective analysis of 91 epileptic pregnant women attending the Severance Hospital Yonsei Medical Center between January 1980 and June 1998. Of the 91 women, data from 84 were available for analysis. Adverse pregnancy outcome in 66 women who were exposed to AEDs during pregnancy were compared with those of 18 controls who were not. The main adverse pregnancy outcome included spontaneous abortions, perinatal deaths, preterm deliveries, fetal growth restriction and congenital anomalies. RESULTS: Epileptic women with AEDs treatment during pregnancy were not significantly different from their controls in the incidence of spontaneous abortions(1.5% vs, 5.5%), perinatal deaths(1.5% vs. 0%), preterm deliveries(3% vs. 5.5%), fetal growth restriction(3% vs. 0%), and congenital anomalies(3% vs 5.5%). An adverse outcome occurred in 8 of 66 women(l2%) in the study group and 3 of 18 control group(16.5%). This difference was not statisitically significant. CONCLUSION: Our study shows that epileptic women who were exposed to AEDs during pregnancy do not have an increased risk of adversed pregnancy outcome than the women who were not.
