RESUMO
Objective: The study aimed to investigate the clinical outcomes of fetuses diagnosed with isolated mega cisterna magna in utero. Methods: A multicenter retrospective cohort study was conducted across 18 university hospitals from 2010 to 2019. Cases diagnosed with isolated mega cisterna magna, defined as a cisterna magna >10 mm with a normal cerebellar vermis and no cystic dilation of the fourth ventricle, were included. Cases with other central nervous system (CNS) anomalies, extra-central nervous system anomalies, chromosomal abnormalities, or congenital infections were excluded. Maternal demographics, prenatal findings, delivery outcomes, and postnatal outcomes were analyzed. Results: The mean gestational age at initial diagnosis was 28.6 ± 3.9 weeks, and the mean anteroposterior diameter of the cisterna magna was 12.5 ± 3.2 mm. Of the 71 cases initially assessed, 48 (67.6%) showed self-regression in utero. Postnatally, 13 cases (18.3%) had persistent isolated mega cisterna magna, whereas 10 cases (14.1%) were diagnosed with other central nervous system anomalies. Among the persistent isolated mega cisterna magna cases, one child exhibited delayed neurodevelopment. There was a higher incidence of isolated mega cisterna magna in male fetuses, which exhibited a significantly larger mean cisterna magna diameter compared with female fetuses (P = .045). Conclusion: Male fetuses exhibited a higher incidence of isolated mega cisterna magna compared with female fetuses and had larger anteroposterior diameters of the cisterna magna. The study demonstrated favorable neurodevelopmental outcomes associated with isolated mega cisterna magna, with self-regression observed in two-thirds of the cases. However, consecutive prenatal and postnatal evaluations for additional central nervous system or extra-central nervous system malformations need to be performed, considering the differences between prenatal and postnatal diagnoses.

OBJECTIVES: Individuals delivered from preeclamptic pregnancies exhibit a long-term increased risk of developing cardiovascular and metabolic diseases, likely caused by aberrant fetal cell reprogramming incurred in utero. The present study investigated the functional impairment and epigenetic changes exhibited by endothelial progenitor cells derived from offspring born to preeclamptic pregnancies. STUDY DESIGN: The capacity of CD133+/C-kit+/Lin- (CKL-) human umbilical cord blood endothelial progenitor cells (EPCs) derived from gestationally matched normal and preeclamptic (nâ¯=â¯10 each) pregnancies to differentiate to form outgrowth endothelial cells (OECs) was assessed by observing both their morphology, and the number and size of generated OECs colonies. Likewise, OECs angiogenic function was evaluated via migration, adhesion, and tube-formation assays. EPCs from preeclampsia were cultured in normal-, and preeclampsia-derived serum-conditioned media to assess the effects of environmental factors on EPC differentiation potency and OEC angiogenic function, and finally, EPCs H3K4, H3K9, and H3K27 trimethylation levels were assayed. RESULTS: The preeclampsia-derived CKL- EPCs exhibited decreased H3K4 and H3K9 trimethylation levels, significantly delayed differentiation times, and a significant reduction in both their number of generated OECs colonies, and exhibited reduced OECs migration, adhesion, and tube formation activities compared to those achieved by the normal-derived EPCs. Interestingly, the reduced differentiation potency of the preeclampsia-derived EPCs was not rescued via exposure to normal serum. CONCLUSIONS: Exposure to preeclampsia significantly and irreversibly reduced CKL- EPC differentiation potency and OEC angiogenic function, likely reflecting incurred irreversible epigenetic changes.

Estrogens are commonly used in gynecologic area, such as oral contraception, hormone replacement therapy, and in vitro fertilization-embryo transfer. Although estrogen is a common cause of acute drug-induced pancreatitis, there has been paucity of report in Korea. Clinical course of estrogen-induced acute pancreatitis is usually mild to moderate, but fetal case can occur. In addition, there can be a latency from the first administration to the symptom. Therefore, physicians should consider the possibility of the disease when a woman taking estrogen or previous history of taking estrogen presents with acute abdominal pain. Here, we report a case of estrogen-induced acute pancreatitis that occurred during the preparation for embryo transfer.
RESUMO
PURPOSE: We examined the frequency of severe perineal injuries according to the use of episiotomy in vaginal deliveries of Korean women. MATERIALS AND METHODS: This is a retrospective cohort study in which 358 consecutive parturients were included. Women were divided into episiotomy (n = 115) and no episiotomy (n = 243) groups. The main outcome was the occurrence of severe (third or fourth degree) perineal injuries. Delivery records and medical documents were reviewed to collect the data. Parametric and nonparametric tests were used as appropriate. RESULTS: There were no significant differences in the frequency of severe perineal injuries between two groups (6.1% (7/115) in episiotomy versus 3.7% (9/243) in no episiotomy group, p = 0.308). Anterior perineal laceration was more frequent (40.3% (98/243) vs. 18.3% (21/115), p < 0.001), but intact perineum was found in 15.6% (38/243) of women in no episiotomy group. Logistic regression analysis was performed to evaluate independent risk factors in the occurrence of severe perineal injuries including maternal age, parity, performance of episiotomy, head position at delivery, length of second stage of labor, birth weight, head circumference, and the use of vacuum during delivery. Only birthweight was a significant factor in predicting severe perineal injuries, and performance of episiotomy did not increase nor decrease the risk of severe perineal injury. CONCLUSIONS: There was no difference in the occurrence of severe perineal injuries according to the use of episiotomy.

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.
RESUMO
BACKGROUND: This study aimed to compare single-port transumbilical total laparoscopic hysterectomy (SPLS-TLH) and four-port total laparoscopic hysterectomy (TLH) in terms of postoperative pain. METHODS: The study enrolled 68 patients who underwent TLH from October 2009 to March 2010 and randomly assigned them to one of two groups. Patient demographics, operative outcomes, and postoperative pain were prospectively examined. RESULTS: Four cases in the SPLS-TLH group were converted to other laparoscopic approaches. The two study groups did not differ in terms of patient demographics and surgical outcomes. Postoperative pain scores, measured using a visual analog scale, did not differ between the two groups. However, significantly higher total requests for analgesics were observed in the SPLS-TLH group (11.3 ± 4.1 vs. 7.7 ± 2.7; p < 0.001). CONCLUSION: Compared with four-port TLH, SPLS-TLH is a feasible approach with comparable operative outcomes. However, reduction of postoperative pain is not evident with SPLS-TLH.

OBJECTIVE: The objective of the study was to compare surgical outcomes and postoperative pain between transumbilical single-port access total laparoscopic hysterectomy (SPA-TLH) and conventional 4-port total laparoscopic hysterectomy (TLH). STUDY DESIGN: We retrospectively reviewed 157 patients who underwent SPA-TLH (n = 52) or conventional TLH (n = 105). A single-port access system consisted of a wound retractor, surgical glove, 2 5 mm trocars, and 1 10/11 mm trocar. RESULTS: The SPA-TLH group had less intraoperative blood loss (P < .001), shorter hospital stay (P = .001), and earlier diet intake (P < .001) compared with the conventional TLH group. There was no difference in perioperative complications. Immediate postoperative pain score was lower in the SPA-TLH group (P < .001). Postoperative pain after 6 and 24 hours was lower in SPA-TLH with marginal statistical significance. CONCLUSION: SPA-TLH is a feasible method for hysterectomy with lower immediate postoperative pain and better surgical outcomes with respect to recovery time compared with conventional TLH.
