Neurogenic potentials of human amniotic fluid-derived stem cells according to expression levels of stem cell markers and ingredients of induction medium

PURPOSE: We investigated the neurogenic potentials of amniotic fluid-derived stem cells (AFSCs) according to the expression levels of stem cell markers and ingredients in the neural induction media. MATERIALS AND METHODS: Four samples of AFSCs with different levels of Oct-4 and c-kit expression were differentiated neurally, using three kinds of induction media containing retinoic acid (RA) and/or a mixture of 3-isobutyl-1-methylxanthine/indomethacin/insulin (neuromix), and examined by immunofluorescence and reverse transcription-polymerase chain reaction (RT-PCR) for their expression of neurospecific markers. RESULTS: The cells in neuromix-containing media displayed small nuclei and long processes that were characteristic of neural cells. RT-PCR analysis revealed that the number of neural markers showing upregulation was greater in cells cultured in the neuromix-containing media than in those cultured in RA-only medium. Neurospecific gene expression was also higher in Oct-4 and c-kit double-positive cells than in c-kit-low or -negative cells. CONCLUSION: The stem cell marker c-kit (rather than Oct-4) and the ingredient neuromix (rather than RA) exert greater effects on neurogenesis of AFSCs.

Intraoperative intraperitoneal chemotherapy with cisplatin in epithelial ovarian cancer / 부인종양

OBJECTIVE: To assess retrospectively the feasibility of intraoperative intraperitoneal (IP) chemotherapy with cisplatin in epithelial ovarian cancer. METHODS: IP chemotherapy during optimal staging surgery was performed in 10 patients who were diagnosed with primary epithelial ovarian cancers between April 2008 and February 2011. Cisplatin (70 mg/m2 in 1 L normal saline solution) was administered in the abdominal cavity for 24 hours postoperatively and then adjuvant chemotherapy was started 2-4 weeks after surgery. Perioperative toxicity of the combined treatment was evaluated until the initiation of postoperative adjuvant chemotherapy. RESULTS: A total of 23 adverse events were observed in 9 of 10 patients (grade 1, 7; grade 2, 13; grade 3, 3; grade 4, 0). In descending order of frequency, adverse events affected the gastrointestinal system (n=14), hematologic system (n=6), pulmonary system (n=2), and genito-urinary system (n=1). The adverse events did not affect adjuvant systemic chemotherapy schedules. One patient experienced disease recurrence in the liver 16 months after surgery. The remaining 9 patients have been well controlled by chemotherapy and/or observation during the follow-up period of 4 to 39 months after surgery. CONCLUSION: Intraoperative IP chemotherapy with cisplatin during surgical procedures is considered feasible for the treatment of primary epithelial ovarian cancer. Further studies, including long-term, prospective and comparative trials, are needed to validate the efficacy of this combined therapy.

Adhesion formation after applying adhesion barrier in laparoscopic gynecologic surgery: Experience of 7 patients / 대한산부인과내시경학회지

OBJECTIVE: Adhesion barrier has been commonly used in gynecologic surgery. The objective of this study is to evaluate the outcome of applying adhesion barrier in preventing adhesion formation after laparoscopic surgery. METHODS: Between March 2000 and March 2010, we retrospectively reviewed the medical records of patients who performed laparoscopic surgery twice at Samsung Medical Center. The patients to whom adhesion barrier was applied at the end of the first laparoscopic surgery and had imaging files of pelvic cavity at second laparoscopic surgery were included. The patients with recurrent endometriosis and pelvic inflammatory disease which can make postoperative adhesion by itself due to the nature of the disease were excluded. RESULTS: Ten patients were eligible to be analyzed. Only 3 among 10 showed adhesion free and we could find de novo adhesion formation in 7 patients at second laparoscopic surgery. Eight patients used Intercede(R) (oxidized regenerated cellulose mesh; Johnson & Johnson, New Brunswick, NJ, USA) and two patients used Guardix(R) (sodium hyaluronic acid solution and carboxymethylcellulose: Hanmi, Seoul, Korea). In six patients, adhesion formation was found at the operation site and one patient showed postoperative adhesion distant from operation site between omentum and anterior peritoneum of pelvic wall. CONCLUSION: We observed adhesion formation despite of prior use of adhesion barrier after laparoscopic gynecological surgery. These results suggest that the use of adhesion barrier alone after gynecologic laparoscopic surgery may not guarantee adhesion prevention.

A case of robotic laparoscopic radical trachelectomy / 대한산부인과학회지

To present a case of successful robotic assisted radical trachelectomy. A nulliparous woman with early cervical cancer underwent a laparoscopic radical trachelectomy and pelvic lymphadenectomy with the da Vinci robot (Intuitive Surgical Inc., Sunnyvale, CA). After the pelvic lymph nodes were found negative on frozen section, the parametria, paracolpia and uterosacral ligaments were dissected transabdominally sparing the ascending branches of the uterine arteries. Cervical transection and vaginal closure were performed transvaginally. Surgical time was 450 min. No perioperative complications were noted. Robotic laparoscopic radical trachelectomy may bridge the gap between laparotomy and laparoscopy for radical trachelectomy.

Correlation between Ultrasonographic Findings of Endometrioma and Endometriosis Stage and Recurrence / 대한산부인과학회지

OBJECTIVE: This study was performed to evaluate of correlation between ultrasonographic findings of endometrosis and endometriosis stage and recurrence. METHODS: We reviewed medical records of fifty-nine patients who admitted the department of Obstetrics and Gynecology of Sanggye Paik Hospital from April 1998 to June 2004 and were surgically confirmed endometriosis stage 3-4. GnRH agonist was injected every 4 weeks after the first injection following initial operation and a total of six doses were injected to a patient. We performed ultrasonographic examination of pre- and post-operation at an interval of 3 or 6 months. The endometriotic ultrasonographic findings were classified into three group; low-level internal echo (LIE), LIE and septation, LIE and hyperechoic wall foci. The correlation between ultrasonographic finding of endometrioma and endometriosis stage and recurrence were analyzed by Fisher's exact test and Pearson's chi-square test. RESULTS: The follow-up periods after operation were about 11.9 months. Typical ultrasonographic findings of endometrioma were observed on 50 of 59 patients, diagnostic performance of ultrasound in the detection of endometrioma had a 84.7% sensitivity in this study. In 50 cases, 48% (n=24) had a only low-level internal echoes, 32% (n=16) had a low-level internal echoes and multiple septation, 20% (n=10) had a low-level internal echoes and hyperechoic wall foci. The most common ultrasonographic findings were LIE (50%) in stage 3, LIE and septation (33.3%) in stage 4. During follow-up we observed ultrasonographic recurrence in 6 (10.2%) cases. There were no statistically significant correlation between ultrasonographic finding and endometriosis stage or recurrence. CONCLUSION: Ultrasound is a convenient and reliable method for diagnosis of endometrioma. But, it appears that ultrasonographic findings of endometrioma not correlate with endometriosis stage or recurrence. Further long term follow-up studies in large scale is needed for correlation between ultrasonographic findings of endometriosis and clinical significance.

Study for umbilical cord plasma leptin in gestational diabetes and normal pregnancy / 대한산부인과학회지

OBJECTIVE: To compare umbilical cord plasma leptin level between infants of mothers with gestational diabetes and infants of control subjects and to evaluate the regulation of leptin in GDM. METHODS: Leptin concentrations were measured in cord blood at birth using a specific radioimmunoassay employing human recombinant leptin (Human Leptin RIA kit; Linco Research, Inc. USA). We compared cord plasma leptin level between gestational diabetes (n=18 women) and control pregnancies (n=21 women). RESULTS: Maternal weight, fetal birth weight, Ponderal index and placental weight were significant variables among the demographic variables. There was statistical difference in cord plasma leptin level between infants of mothers with gestational diabetes and infants of control subjects (Control subjects: 4.8 [3.7-7.9]ng/mL, GDM women: 8.0 [6.6-11.9]ng/mL, P=0.022). There was also statistical difference in the ratio between cord plasma leptin level and birth weight (Control subjects: 0.001 [0.001-0.002]ng/mL/gm, GDM women: 0.002 [0.002-0.003]ng/mL/gm (P=0.022)), and between cord plasma leptin level and Ponderal index (Control subjects: 0.280 [0.217-0.579], GDM women: 0.605 [0.452-1.005], (P=0.008)). There was no difference in gender. CONCLUSION: We found significant difference in umbilical cord plasma leptin level and adjusted leptin level for fetal birth weight, Ponderal index and placental weight between infants of mothers with gestational diabetes and infants of control subjects. It is suggested that umbilical cord plasma leptin is produced by fetal fat tissue, but it is more complicatedly regulated by placenta and other factors in gestational diabetes.

Performance of Risk Indices for Prediction of Osteoporosis in Post- and Perimenopausal women / 대한산부인과학회지

OBJECTIVE: To examine the ability of published osteoporosis risk indices for prediction of osteoporosis in post- and perimenopausal women. METHODS: Subjects included 1559 of post- and perimenopausal women, 45 year old and older, recruited from Menopause Clinic from January 2002 to June 2004. Their bone mineral density (BMD) of femur neck was determined by dual energy x-ray absorptiometry (DXA), and their historical and clinical risk factors were assessed. We employed the World Health Organization (WHO) diagnostic criteria of osteoporosis for calculating the T scores, using race/ethnic and gender-specific young adult mean values. We applied 6 published osteoporosis risk indices (OSTA, ORAI, SCORE, SOFSURF, ABONE, NOF practice guideline) to each subject. Also, the predictive abilities of risk indices were assessed using the area under receiver operating characteristic (ROC) curve. RESULTS: The prevalence of osteoporosis and osteopenia was 8.7% and 32.6% for femur neck, 16.0% and 30.1% for lumbar spine, respectively. The prevalence of osteoporosis for femur neck was increased dramatically in the coming decades (1.6% for fifties, 8.7% for sixties, 43.0% for seventies, 64.1% for over eighties). ROC curve for predicting osteoporosis according to femur neck by OSTA showed the area under the curve (AUC) of 0.920. Sensitivity, specificity, and positive predictive value (PPV) were 93.4%, 75.4%, 26.6%, respectively. AUC for ORAI, SCORE, SOFSURF, ABONE, and NOF practice guideline was 0.896, 0.916, 0.871, 0.846, and 0.856, respectively. CONCLUSION: Validated risk indices have varying complexity, but similar sensitivity, specificity, and PPV for identifying individuals who are likely to have osteoporosis. However, OSTA is the most excellent risk index and simple tool.
