Benign multicystic peritoneal mesothelioma (BMPM) is rare and difficult to diagnose before surgery. We report a case of BMPM incidentally discovered during laparoendoscopic single site surgery (LESS) for treatment of a pelvic mass. A 47-year-old Korean menopaused woman presented to our outpatient clinic with a pelvic mass. She had a history of right ovary cystectomy with adhesiolysis at a local hospital in 2010. Imaging study of the pelvis revealed a multilocular cystic mass. LESS was performed and multiple grapelike clusters of cysts were seen in the uterus, cul-de-sac, both adnexa, pelvic wall, and omentum...

Gastric type mucinous endocervical adenocarcinomas of the uterine cervix (GAC) are a newly classified mucinous subtype with morphologically in 2014, WHO. They have a much more aggressiveness and show unusual metastatic patterns compared to usual type endocervical adenocarcinoma. They tend to present at higher stage and even in stage I, they have worse survival. Therefore, differential diagnosis of GAC from the usual type of endocervical adenocarcinoma is very important because they are related to a significant risk of recurrence and decreased 5-year disease-specific survival...

Coronary arteriovenous fistula (CAVF) is a rare condition defined as an anomalous termination of the coronary arteries. The etiology of CAVF is either congenital or acquired, and iatrogenic CAVF is most commonly caused by cardiovascular surgery or percutaneous intervention. Most of the prenatally diagnosed CAVFs were related to complex heart disease, and only few cases of an isolated CAVF have been reported to date. We successfully diagnosed an isolated CAVF by fetal echocardiography at 25.3 weeks of gestation...

We reported a case of secondary abdominal pregnancy with placental implantation into the fallopian tube, diagnosed at 16 weeks, in a woman admitted to the emergency room complaining of syncopal attacks. The best approach would be termination of the pregnancy, taking into consideration the high risk to the mother and the low possibility of alive and healthy birth. We had to perform an urgent surgical intervention due to the fact that the patient was in a clinically unstable condition, which was related to hemoperitoneum...

Objective: We compared the expression levels of Müllerian inhibiting substance (MIS)/anti-Müllerian hormone type II receptor (AMHRII) in uterine myoma and adenomyosis to evaluate the possibility of using MIS/anti-Müllerian hormone (AMH) as a biological regulator or therapeutic agent in patients with uterine leiomyoma and adenomyosis. Methods: We studied normal uterine myometrium, leiomyoma, endometrial tissue, and adenomyosis from 57 patients who underwent hysterectomy for uterine leiomyoma (22 cases) or adenomyosis (28 cases) and myomectomy for uterine myoma (7 cases)...

Objective: This study aimed to analyze the association of socioeconomic factors, acculturation, and body mass index (BMI) as the first large prospective cohort study to determine the state of health of Vietnamese-born migrant women residing in Korea. Methods: Participants were Vietnamese marriage-based immigrant women living in Korea. Data (n=1,066) was collected during both periods of baseline (2006-2011) and follow-up (2012-2014) in 34 cities in Korea. Results: The results show that acculturation stress is relatively low among participants...

Objective: Endometriosis is a common and recurring gynecologic disease which have afflicting females of reproductive age. We investigated the efficacy of long-term, post-operative use of dienogest for ovarian endometrioma. Methods: We studied 203 patients who had undergone laparoscopic or robotic surgery for ovarian endometrioma, and were administrated dienogest 2 mg/day beginning in July of 2013, and continuing. We evaluated side effects of dienogest and ultrasonography was performed every 6 months to detect potential recurrence of endometrioma (2 cm) in these post-surgical patients...

Objectives: We investigated whether luteal estrogen administration and an early follicular Gonadotropin-releasing hormone antagonist (E/G-ant) priming protocol improves clinical outcomes in poor responders to controlled ovarian stimulation for in vitro fertilization (IVF)-embryo transfer, and identified underlying mechanisms. Methods: This restrospective study consisted of 65 poor responders who underwent the E/G-ant priming protocol. Sixty-four other poor responders undergoing conventional protocols without pretreatment were included as the control group...

Objective: Indications for preimplantation genetic diagnosis (PGD)/preimplantation genetic screening (PGS) cycles and clinical outcomes were evaluated at CHA Gangnam Medical Center. Methods: This is retrospective cohort study. All patients (n=336) who went through in vitro fertilization (IVF)-PGD/PGS cycles (n=486) between January 2014 and December 2015 were included in Fertility Center of CHA Gangnam Medical Center. Patients underwent IVF-PGD/PGS with 24-chromosome screening...

Objective: To detect the possible clinicopathologic factors associated with parametrial involvement in patients with stage IB1 cervical cancer and to identify a cohort of patients who may benefit from less radical surgery. Methods: We retrospectively reviewed 120 patients who underwent radical hysterectomy and pelvic lymphadenectomy as treatment for stage IB1 cervical cancer. Results: Overall, 18 (15.0%) patients had parametrial tumor involvement...

Objective: The objective of the study was to compare cosmetic outcomes and overall satisfaction rate of cesarean section scar between conventional subcuticular suture and intradermal buried vertical mattress. Methods: Patients were enrolled to the study by chart review. A scar assessment was obtained retrospectively through a telephone survey. The patient component of the patient and observer scar assessment scale (POSAS) was utilized along with the overall satisfaction of the patient regarding their cesarean section scar and their willingness to choose the same skin closure technique when anticipating their next cesarean section...

Objective: The purpose of this study was to investigate the effects of estradiol on the expression of hypoxia-inducible factor (HIF)-1α and the differentiation of trophoblasts in human first trimester villous explant cultures. Methods: Villous explant cultures were established from first trimester human placentas (6-8 weeks of gestation, n=3). Normal villous tissues were explanted on Matrigel and incubated under 3% O2 tension for 5 days. To evaluate the effects of estradiol on the villous explant cultures, 1 ng/mL of estradiol was added to the culture medium...

Objective: In terms of efficacy, several previous studies have shown that the success rate in inhibiting preterm labor was not different between magnesium sulfate and ritodrine. However, there is a paucity of information regarding the efficacy of both medications after consideration of intra-amniotic infection, which is one of the most important prognostic factors in patients of threatened preterm birth. The objective of this study was to compare the efficacy and safety of magnesium sulfate with that of ritodrine in preterm labor...

Methods: The study population included 64 women who were candidates for intravenous MgSO4 treatment for preterm labor. Serial blood samples were taken and measured total magnesium (T-Mg), ionized magnesium (I-Mg), total calcium (T-Ca), and ionized calcium (I-Ca) levels every one-week interval (1st, 2nd, 3rd)...
