A Case of Partial Hydatidiform Mole with a Coexistent Live Fetus / 대한산부인과학회지

Hydatidiform moles are generally separated into two classifications. Complete hydatidiform moles are characterized by cystic swelling of all villi, often pronounced trophoblastic hyperplasia, lack of fetal parts, all 46 chromosomes of paternal origin, and a major risk for persistent trophoblastic tumor. Partial hydatidiform moles appear to be a milder version of complete moles with both normal and cystic villi, focal trophoblastic hyperplsia, a fetus or indication of previous fetal existence, 69 chromosomes with a maternal contribution, and a malignant potential less than described for complete moles. Hydatidiform mole with coexistent fetus is a very rare phenomenon, with an estimated incidence of 0.005 to 0.01 percent of all pregnancies. Due to advances in cytogenetics and ultrasonography, now permit the diagnosis of this pregnancy antenatally. However this unusual pregnancy has the risks of malignant change and severe medical complications, so it is a dilemma to decide continuation or termination of pregnancy. We experienced a case of partial hydatidiform mole with coexistent live fetus, which was diagnosed by ultrasonography at 12 gestational weeks, and confirmed normal karyotype (diploid) of the coexistent fetus. A brief reviews of related literature was done.

Perinatal outcomes in hyperemesis gravidarum patients as compared to normal pregnancy / 대한산부인과학회잡지

OBJECTIVE: To study perinatal outcomes in hyperemesis gravidarum (HG) patients as compared to normal pregnancy. METHODS: We performed retrospective analysis of pregnancy records of obstetric admission during 9-years period (between 1995 and 2003). We identified 77 women who admitted for control of HG after diagnosed as HG and delivered during the study period. Women treated as out-patients for hyperemesis and delivered at other hospital were excluded. Multiple gestation and stillbirth were also excluded from analysis. Subjects were stratified into groups of mild and severe HG according to the presence of at least one of the following criteria: ketonuria, increased hematocrit, and/or abnormal electrolytes. All patients without HG on whom records were available and who delivered during the study period were included as controls. Student T-test, chi square test, Kruskal-Wallis test and Mann-Whitney's U test were used. RESULTS: Among 77 women, 31 patients were diagnosed as having mild HG and 46 patients as having severe; 41205 patients were defined as controls. Maternal age, gravidity, maternal weight gain from preconception to delivery, maternal anemia were not significantly different between hyperemesis patients and control group. Mean birth weight, mean gestational age, neonatal sex ratio, Apgar score, delivery route were not significantly different. Pregnancy outcome variables and maternal characteristics for mild, severe HG and control group were also similar. CONCLUSION: Women with hyperemesis have similar maternal characteristics to the general population and have similar pregnancy outcomes. And there were no significantly difference between mild and severe hyperemesis patients.
