OBJECTIVE: To evaluate the risk of emergency cesarean section according to the prepregnancy body mass index (BMI) and gestational weight gain per the 2009 Institute of Medicine guidelines. METHODS: A retrospective analysis of data from 2,765 women with singleton full-term births (2009 to 2012) who attempted a vaginal delivery was conducted. Pregnancies with preeclampsia, chronic hypertension, diabetes, planned cesarean section, placenta previa, or cesarean section due to fetal anomalies or intrauterine growth restriction were excluded. Odds ratios (ORs) and confidence intervals (CIs) for emergency cesarean section were calculated after adjusting for prepregnancy BMI or gestational weight gain. RESULTS: Three-hundred and fifty nine (13.0%) women underwent emergency cesarean section. The adjusted OR for overweight, obese, and extremely obese women indicated a significantly increased risk of cesarean delivery. Gestational weight gain by Institute of Medicine guidelines was not associated with an increased risk of cesarean delivery. However, inadequate and excessive weight gain in obese women was highly associated with an increased risk of emergency cesarean section, compared to these in normal BMI (OR, 5.56; 95% CI, 1.36 to 22.72; OR, 3.63; 95% CI, 1.05 to 12.54; respectively), while there was no significant difference between normal BMI and obese women with adequate weight gain. CONCLUSION: Obese women should be provided special advice before and during pregnancy for controlling weight and careful consideration should be needed at the time of vaginal delivery to avoid emergency cesarean section.

PURPOSE: Fast MRI has provided detailed and reproducible fetal anatomy. This study was performed to evaluate the usefulness of fetal MRI for prenatal diagnosis. MATERIALS AND METHODS: Fifty-six fetuses with congenital abnormalities on ultrasonography were evaluated by fetal MRI from 2001 to 2004 in Severance Hospital. Final diagnosis was made by postnatal pathology, postnatal MRI, and other modalities (such as ultrasound, retrograde pyelogram). A 1.5-Tesla superconductive MR imaging unit was used to obtain half-Fourier acquisition single-shot turbo spin images. RESULTS: Of the 56 fetuses, intracranial abnormalities were found in 26 fetuses, intraabdominal abnormalities in 17 fetuses, intrathoracic in 6 fetuses, head and neck in 5 fetuses, and other sites in 2 fetuses. There were six cases in which the diagnoses of fetal MRI and ultrasonography differed. In such cases, fetal MRI provided more exact diagnosis than ultrasonography (5 vs. 0). Three fetuses with intracranial abnormalities on ultrasonography were diagnosed as normal by fetal MRI and in postnatal diagnosis. CONCLUSION: Although ultrasonography is known as a screening modality of choice in the evaluation of fetus because of the cost-effectiveness and safety, the sonographic findings are occasionally inconclusive or insufficient for choosing the proper management. Thus, in this study, we suggest that fetal MRI is more useful than ultrasonography for the evaluation of intracranial abnormalities in some instances. For prenatal counseling and postnatal treatment planning, fetal MRI can be informative when prenatal ultrasonography is inadequate and doubtful.

The incidence of acute leukemia in pregnancy is estimated to be about 1 per 75000 pregnancies, and the incidence of lymphocytic leukemia is known to be lower than myelocytic leukemia. Pregnancy dose not affect the course of acute leukemia, but thrombocytopenia, anemia and leukopenia resulting from leukemia may lead to hemorrhage, infection, and insufficient supply of oxygen and nutrition to fetus. The most important factor for chemotherapy is gestational age. Since no evidence on adverse effect of chemotherapeutic agents on fetus when given after the first trimester, aggressive chemotherapy is recommended during pregnancy. However, during chemotherapy, caution regarding risk of spontaneous abortion, intrauterine fetal growth retardation, teratogenicity, intrauterine fetal death, fetal immunosupression and preterm labor should be taken. Acute leukemia in pregnancy is extremely rare, so treatment and management of the pregnant mother bearing viable fetus in her 3rd trimester is not established clearly. We experienced a patient with acute lymphocytic leukemia who was first diagnosed at 27 gestational weeks and immediately started with chemotherapy. But due to preterm labor and impending fetal distress, emergency cesarean section was performed at 28 gestational weeks. We present this patient along with past experiences of acute leukemia in pregnancy.

OBJECTIVE: To investigate the differential expression of junctional proteins in the normal and preeclamptic human placenta and the effect of ginsenoside Rk1 in junctional proteins. METHODS: Placental tissues from 10 women with severe preeclampsia and 5 normal women were collected at the time of their cesarean section. Five of 10 preeclamptic women were complicated with intrauterine growth restriction (IUGR). Immunohistochemistry and Western blotting was employed to localize junctional proteins (zo-1, occludin and plakoglobin) positive cells. The placental explant culture was performed to investigate if Rk1 can attenuate the expression of junctional proteins (zo-1, occluding and plakoglobin) induced by deferoxamine-induced hypoxia. Rk1 was treated at the day 3 and Western blot analysis was performed for protein quantification. RESULTS: There was no different expression of zo-1 and plakoglobin among all the study groups. Occludin showed negative at the endothelial cells of the terminal villi in both normal and preeclampsia groups. At the endothelial cells of the stem villi, occludin was detected in both normal and severe preeclamptic placenta with normal fetal growth. However, severe preeclampsia with IUGR were decreased expression of occludin at the endothelial cells of the stem villi. When we administered Rk1 to the placenta treated with DFO, expression of occludin was not different. CONCLUSION: The placental expression of zo-1 and plakoglobin were not different among the study groups, while that of occludin was significantly decreased at the endothelium of stem villi in severe preeclampsia with IUGR. Rk-1 showed no effect on the placental junctional proteins. These results suggest that occludin may play a role in pathophysiology of fetal growth restriction in utero.

OBJECTIVE: We studied relationship between average amount of fish consumption and blood mercury level in pregnant women, in addition we would like to know the blood mercury level in pregnant women in Korea and we compared the initial blood mercury level in pregnant women and followed up how much blood mercury level decreased after counseling and prenatal education. METHODS: Pregnant women who received prenatal care at the Yonsei medical center from March 2004 to September 2004, were targeted. They were divided into two groups. One was the study group who was educated to restrict the intake of fish, the other was the control group who was not given any prenatal education. We measured their blood mercury level and followed up until 2nd and 3rd trimester, to find out the differences between two groups. RESULTS: Out of the 63 pregnant women who participated in our study, we followed up 11 pregnant women in the study group and 13 pregnant women of control group. The initial mean blood mercury level of both groups was 2.94 (0.14-10.75) microgram/L. Blood mercury level in fish eating group of more than 4 times a month was higher than the others, which was statistically significant (p=0.02). Followed up blood mercury levels were increased in both groups, but there was not statistically significant between two groups. CONCLUSION: Pregnant women who consume a large amount of fish may have high blood mercury level. As fish intake seems to influence blood mercury level, to lower their blood mercury level, periconceptional education to decrease fish consumption might be necessary.

BACKGROUND: As single donor platelets (SDP) has been increasingly used, the quality of SDP, especially apheresis-induced platelet activation, has become a major issue. This study evaluated the activation of SDP platelets prepared with three different cell separators that are currently being used at the Korean Red Cross. METHODS: CD62p, CD63 and CD42 were measured in 35 units of SDP prepared with Amicus (Baxter, Deerfield, IL, USA), MCS+ (Haemonetics, Braintree, MA, USA), or Trima (Gambro BCT, Lakewood, USA) using flow cytometry. RESULTS: Expression of CD62p gradually increased with storage time, but no difference in expression was noted between cell separators. Expression of CD63 also increased with storage time and platelets prepared with the Amicus displayed significantly higher CD63 expression 72 and 120 hours after collection compared to those prepared with MCS+ and Trima. Expression of CD42b tended to decrease with storage time, but this was only significant for Amicus 120 hours after collection. No difference in CD42b expression was noted between cell separators. CONCLUSIONS: Platelet activation increased with storage time, and platelet activation was more pronounced in the platelets prepared with the Amicus. However, because in vitro results of platelet activation does not necessarily reflect in vivo platelet function and survival, additional studies are needed to clarify clinical effectiveness of activated platelets.

BACKGROUND: Epidural pain control has been used extensively for postoperative pain management, but nausea, vomiting and pruritus associated with morphine and fentanyl administration remain intractable problems. The aim of this study is to find the optimal epidural droperidol dosage for reducing the side effects of epidural morphine and fentanyl. METHODS: 140 patients randomly sampled and undergoing vaginal total hysterectomy were divided into 7 groups. Groups I and IV, and groups II and V, and groups III and VI, received 5 mg, 3.75 mg, 2.5 mg of droperidol by 2-day infusion pump through the indwelling epidural catheter, respectively. Group IV, V, VI patients received 1.25 mg of bolus droperidol through the indwelling epidural catheter at the time of peritoneal closure. As group VII was the control group, these patients received only epidural analgesics (morphine 10 mg, fentanyl citrate 300 microgram and 0.05% bupivacaine 100 ml) by 2-day infusion pump. RESULTS: Droperidol significantly reduced the incidence and severity of postoperative nausea, vomiting and itching sensation compared with the control group but verbal rating scale (VRS) of sedation was increased with the dosage of droperidol. There was no significant difference in the intensity of analgesia between the there groups. CONCLUSIONS: An effective epidural droperidol dosage for reducing postoperative nausea, vomiting and pruritus due to epidural pain control is 2.5 mg by 2-day infusion pump.

Presentation of antigen in a suitable form to lymphocytes is prerequsite for the initiation of primary immune response. Dendritic cells (DC) provide an effective pathway for presenting antigens to lymphocytes in situ. The aim of this study was to establish a dendritic cell-line from human tonsils and to investigate the changes in surface phenotype during culture. Immunohistochemical studies using various surface markers indicated that cultured DC were follicular dendritic cells (FDC) from human tonsils. Cultured DC showed typical dendritic morphology at early stage of culture. Their shape changed into fibroblast-like cells over culture time. Surface phenotype study suggested that cultured DC were distinct from human fibroblast. Antigenic pattern of FDC was changed during culture; I-ILA-DR antigens decreased and HJ2 antigens increased with aging of culture. Functional characteristics of human tosillar FDC will be investigated in the future.
