RESUMO
These are natural inhibitors of coagulation, and deficiencies of any of these factors is referred to as thrombophilia. The identified main causes of thrombophilia are deficiencies of antithrombin III, protein C, or protein S, resistance to actived protein C associated with Factor V Leiden mutation, and inherited hyperhomocystinemia. Inherited and acquired thrombophilias may also contribute to pathophysiological processes involved in recurrent pregnancy loss, fetal death, intrauterine growth restriction, placental abruption, placental infarction, and pre-eclampsia. Various therapeutic protocols with low-molecular-weight heparin (LMWH) were used. because it is associated with a low incidence of osteoporosis and thrombocytopenia. We experienced the two cases of successful deliveries by Cesarean section following a successful pregnancy maintenance in thrombophilia. we administered LMWH to prevent thromboembolism. one patient was the primi-gravidarum, with inherited thrombophilia, who has the familial history of pulmonary embolism and deep vein thrombosis. the other was the multi-gravidarum, with acquired thrombophilia, who has the past medical history of pulmonary embolism.

OBJECTIVE: To determine whether unexplained elevation of maternal serum alpha-fetoprotein(MSAFP) is associated with adverse outcomes in pregnancies complicated by placenta previa. METHODS: One hundred and five pregnant women with placenta previa between January 1995 and March 1999 were included in this study. They underwent the triple test at 14 to 22 gestational weeks. These 105 pregnant women were stratified into two groups by MSAFP at 2.0MOM. The outcomes of pregnancy in high MSAFP(>or=2.0MOM) group were compared with those in normal MSAFP(or=2.0 MOM). Eleven out of 632 pregnant women with high MSAFP were having placenta previa. 3. The incidence of preterm birth was significantly high in high MSAFP group with placenta previa.(p<0.001) 4. Women with unexplained elevated MSAFP and having placenta previa showed the increased risk for preterm delivery (p<0.05), preeclamsa (p<0.001), and bleeding in third trimester (p<0.001), but not placenta accreta, placenta abruption, cesarean hysterctomy and intrauterine fetal death. CONCLUSION: We concluded that unexplained elevated levels of midtrimester MSAFP in complicated placenta previa were associated with the elevated risk of preterm delivery, preeclamsia and bleeding in the early third trimester, but not placenta accreta, placenta abruption, cearean hysterectomy and intrauterine fetal death.

OBJECTIVE: To evaluate the efficacy of prenatal multiplex PCR with chorionic villi, in the case of family history of DMD due to exon deletion. METHODS: DNA was extracted when cells' size are 1x 106 on T- flask surface area reach to 25 cm2 after 2 weeks from sex confirmation. Average DNA concentration was 50-100 ng and multiplex PCR test was performed from DNA extraction. RESULT: PCR was done for 17 exons devided into 4 groups. Seventeen exons were all amplified with their right size. CONCLUSIONS: This method is DNA analysis for prenatal diagnosis of DMD with chorionic villi in the family of DMD. This is useful when preimplantation genetic diagnosis is not available.

Hydrops fetalis is diagnosed when abnormal fluid collections are manifest in two or more fetal compartments, including abdominal ascites, pleural effusions, pericardial effusions, skin edema, polyhydroamniosis and placental edema. Although fetal hydrops was hystorically most commonly associated with Rh blood group isoimmunization, the availability of Rh immunoglobulin has increased the proportion of fetuses affected due to nonimmune etiologies. We have experienced a case of nonimmune hydrops fetalis at 32 weeks of gestation in a 27-year-old woman and reported that with brief review of related literatures.
