Aim Preoperative autologous blood donation ( PAD) has the advantages over allogeneic blood transfusion of theoretically no risk of viral infection and alloimmunization. However, there are some concerns regarding PAD in pregnant women, as they sometimes become anemic and adverse effects such as low blood pressure could be harmful to fetuses. In our hospital, the PAD program was implemented in 2006 and has been used in pregnant women at high risk of massive hemorrhage. In this study, the safety of PAD in pregnant women and its efficacy for avoiding allogeneic blood transfusion were investigated. Methods The hospital records of pregnant women who delivered at our hospital from January 2009 to June 2012 were reviewed and those who were enrolled in the PAD program for predicted massive hemorrhage were analyzed. Results Among the total of 3095 deliveries, 69 cases enrolled in the PAD program were analyzed. Blood donation was performed 189 times for the 69 cases. The median donated blood volume was 1200 m L (range, 400-2000). The mean blood loss during delivery was 1976 ± 1654 m L. Autologous blood was transfused in 64 cases. Allogeneic blood transfusion was required in five cases of massive blood loss exceeding 5000 m L. In the other 64 cases, no additional allogeneic blood transfusion was required. No adverse events were observed in either the pregnant women or fetuses. Conclusion For pregnant women at a high risk of massive hemorrhage, our PAD program was safe and effective for avoiding allogeneic blood transfusion. [ABSTRACT FROM AUTHOR]

Aim Endometriosis is a chronic inflammatory disease. Sirtuin 1 ( SIRT1) plays a role in regulation of inflammation. The role of SIRT1 in endometriosis remains unknown. We here addressed the anti-inflammatory effects of SIRT1 on endometriosis. Methods The expression of SIRT1 in human ovarian endometriomas and eutopic endometria were examined using immunohistochemistry and reverse transcription polymerase chain reaction ( RT-PCR). Endometriotic stromal cells ( ESC) obtained from endometriomas were exposed to either resveratrol or sirtinol, an activator or inhibitor of sirtuins, respectively, and tumor necrosis factor ( TNF)-α-induced interleukin ( IL)-8 release from the ESC was assessed at m RNA and protein levels. Results Both immunochemistry and RT-PCR demonstrated that SIRT1 was expressed in ESC and normal endometrial stromal cells. Resveratrol suppressed TNF-α-induced IL-8 release from the ESC in a dose-dependent manner while sirtinol increased IL-8 release. Conclusion These opposing effects of SIRT1-related agents suggest that IL-8 release from the ESC is modulated through the SIRT1 pathway. Resveratrol may have the potential to ameliorate local inflammation in endometriomas. [ABSTRACT FROM AUTHOR]

Aim The purpose of our study was to evaluate the efficacy of laser ablation as a conservative treatment for cervical intraepithelial neoplasia 3 ( CIN3) and assess whether the human papillomavirus ( HPV) test is useful to predict recurrence after treatment. Materials and Methods A total of 134 patients who received laser ablation for treatment of CIN3 were enrolled in this study. During the follow-up period, patients were followed with cytological and colposcopic evaluations. Recurrence of CIN3 was regarded as the primary end-point. HPV genotype was tested before and after treatment. Post-treatment cumulative recurrence rates were estimated and comparisons by both patient age and HPV genotype were performed. Results Overall cumulative recurrence rate of CIN3 in the first year after treatment was 22.6% for all patients. No significant correlation was shown between patient age and recurrence. Patients infected by specific genotypes (16, 18, 31, 33, 52, and 58) frequently failed to clear the infection after treatment. The 1-year recurrence-free survival in those positive after treatment for eight high-risk genotypes (16, 18, 31, 33, 35, 45, 52, and 58) was significantly lower (66.7%), compared to that in those positive for other high-risk types (78.6%). The recurrence-free survival of those who remained HPV-positive after treatment was significantly lower than those who turned negative. Conclusion Laser ablation should be performed prudently with appropriate patient counseling about recurrence rate. Considering its minimal invasiveness, laser ablation is effective, especially for young patients who are negative for eight high-risk genotypes. With regard to HPV testing, although genotyping has significant value for predicting recurrence, screening for all genotypes warrants further evaluation. [ABSTRACT FROM AUTHOR]

Aim The aim of this study was to identify factors that can predict clinical course among patients hospitalized with pelvic inflammatory disease ( PID). Methods Ninety-three patients who needed hospitalization with a diagnosis of PID were retrospectively studied. Patients who were discharged within 7 days by conservative treatment were defined as favorable course cases ( n = 44). Patients who needed more than 7 days of hospitalization and/or surgery were defined as poor course cases ( n = 49). Twenty variables were evaluated by univariate and logistic regression analysis: age, history of pregnancy/delivery, gynecological open/laparoscopic surgery, PID, oral contraceptives/intrauterine device use and intrauterine operation before onset, body temperature, signs of peritoneal irritation, vomiting/diarrhea, abnormal vaginal discharge, endometriosis/fibroid/adenomyosis/any cystic lesion detected by ultrasonography, white blood cell counts/C-reactive protein ( CRP) levels . The cut-off value was calculated by receiver-operator curve ( ROC) analysis. Results Factors associated with poor clinical course were advanced age ( P < 0.01), history of gynecological open surgery ( P < 0.05), any cystic lesion detected by ultrasonography ( P < 0.05) and high CRP levels ( P < 0.05). High CRP levels and intrauterine operation before onset were independently associated with poor clinical course. The cut-off value for CRP was 4.4 mg/dL. Conclusion This study identified variables that can predict poor clinical course of PID. These results can assist gynecologists with identifying patients at risk and optimizing the choice of management. [ABSTRACT FROM AUTHOR]

Clinical outcome of confined placental mosaicism ( CPM) is varied, from normal pregnancy to intrauterine fetal death. It has been suggested that CPM for trisomy 2 is less likely to cause serious adverse effect on pregnancy. We hereby report a case of CPM for trisomy 2, which presented severe fetal growth restriction ( FGR) and placental abnormalities. A 30-year-old woman was referred to our hospital at 17+2 weeks because of marked FGR. Ultrasonography demonstrated prominent placental hypertrophy with multiple focal defects without any fetal structural abnormalities. Amniocentesis at 18+3 weeks revealed normal karyotype. Fetal growth rate worsened with gestational weeks, reaching −7 standard deviation at 36 weeks. At 37 weeks, the fetal condition suddenly deteriorated, ending in a stillbirth of a 756-g female baby. Postnatal cytogenetic analysis by array comparative genomic hybridization revealed trisomy 2 of the chorionic villi, and CPM for trisomy 2 was suggested as the cause of FGR and placental abnormalities.

Aim The aim of this study was to review diagnostic/therapeutic strategies of umbilical endometriosis managed in our department and evaluate the effectiveness of these strategies. Methods Medical records for patients with diagnosis of endometriosis managed from 1999 through 2011 in the University of Tokyo Hospital were retrospectively reviewed. Cases with diagnosis of umbilical endometriosis were identified. Clinical information of age, gravida, parity, histories of surgery and oral contraceptive ( OC), management for the disease prior to the first visit, symptoms, patients' desire for pregnancy, diagnostic/therapeutic methods and prognosis were reviewed and summarized. Results During the period, 2530 patients with diagnosis of endometriosis were identified. Seven patients had diagnosis of umbilical endometriosis, giving an incidence of 0.29% of all endometriosis cases and 5.6% of extragenital endometriosis cases. A definitive diagnosis was made by histological examination following a biopsy (two cases) or a resection (three cases). A clinical diagnosis was made by empirical treatment with OC (one case) or dienogest (one case). With regard to therapy, three patients chose expectant management and did not require therapeutic intervention. Three patients began OC and symptoms were well controlled in all patients. One patient who wished to conceive chose a wide resection followed by umbilical reconstruction. She became pregnant afterwards and recurrence was not reported. Conclusion There are various options of diagnostic/therapeutic strategies, such as empirical treatments and OC that can provide individualized management of umbilical endometriosis, congruent with the severity of patient symptoms, age and desire for pregnancy.

Ovarian fibroma can occur in young women of reproductive age. Despite its benign feature, most surgical removals are done in open surgery with oophorectomy. However, an ovarian-sparing tumor resection can be an option, especially for an exophytic type of fibroma, which accounts for more than half of ovarian fibromas. Here we report a case of exophytic ovarian fibroma in a young woman treated by laparoscopic ovarian-sparing surgery. A 27-year-old woman presented with a pelvic mass. Magnetic resonance imaging revealed an 11 cm × 8 cm solid mass connected to the normal-appearing left ovary by a pedicle-like structure. A clinical diagnosis of an exophytic ovarian fibroma was made, and laparoscopic ovarian-sparing surgery with an intraoperative pathological examination was planned. The tumor was resected by cutting the pedicle, morcellated in a pouch and removed. All procedures were performed laparoscopically and the affected ovary was completely preserved. Having confirmation of its benign characteristics by the intraoperative examination, no further excision was performed. The patient conceived 3 months after the surgery and no recurrence was reported. We propose that gynecologists should consider laparoscopic ovarian-sparing surgery for exophytic ovarian fibroma in women of reproductive age. [ABSTRACT FROM AUTHOR]

A uterine artery pseudoaneurysm (UAP) is a rare but life-threatening complication that can occur after gynecologic surgery. Herein, we present a case of a 38-year-old woman who presented with massive uterine bleeding one month after a laparoscopically assisted myomectomy. Although the bleeding ceased spontaneously, a massive hemorrhage reoccurred three weeks thereafter, and a ruptured perfusion sac at the right uterine artery was identified by computed tomography angiography and ultrasonography. The patient was treated with transfemoral catheter embolization of the right uterine artery, and complete resolution of the UAP was successfully obtained. Our case suggests that a UAP may be a cause of unexplained repetitive metrorrhagia after myomectomy. [ABSTRACT FROM AUTHOR]

Low-grade endometrial stromal sarcoma (ESS) is a rare neoplasm that is generally estrogen-receptor- and progesterone-receptor-positive and develops in premenopausal women. Although tamoxifen treatment is associated with an increased risk of ESS, the effect of other selective estrogen receptor modulators, including toremifene, on the risk of ESS is not clear. A 61-year-old postmenopausal woman was treated with toremifene as an adjuvant therapy for breast cancer. A cystic mass developed during the treatment, with gradual growth in the uterine myometrium. The patient was treated with hysterectomy and bilateral salpingo-oophorectomy, and the tumor was diagnosed as low-grade ESS (stage IA) with estrogen-receptor and progesterone-receptor. The patient discontinued toremifene and has been progression-free for 21 months. Our data suggest that toremifene might be associated with the development of ESS in certain patients through its estrogen-like effects in the uterus. [ABSTRACT FROM AUTHOR]

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a cardiac disease that affects the right side of the heart and causes ventricular arrhythmias. It is considered as the most common cause of sudden cardiac death in young adults. However, risk and optimal management of ARVC during pregnancy and delivery remain unclear due to the small number of reported cases. Here we report a case of successful management of pregnancy and delivery in a patient with ARVC, who had a history of sustained ventricular tachycardia from her previous pregnancy.

Aim: Platinum is a milestone drug against gynecologic malignancies. The purpose of this retrospective study was to investigate the feasibility of replacing carboplatin with nedaplatin in patients who had developed a hypersensitivity reaction to carboplatin. Material and Methods: Fifteen patients with recurrent gynecologic cancer (12 ovarian, 1 fallopian tube, 1 endometrial and 1 cervical cancer) who had experienced a hypersensitivity reaction to carboplatin and a possible clinical indication for continuing treatment with platinum were treated with nedaplatin (80 mg/m2)-containing regimen. Results: The total number of nedaplatin cycles given was 137 (range 1-29). Four (27%) patients developed hypersensitivity reactions on the second, second, fourth, and ninth administration, respectively. The severities of all the hypersensitivity reactions were grade 3 or less. The other 11 patients (73%) had no nedaplatin-associated hypersensitivity reactions. The incidence of hypersensitivity reactions in the paclitaxel and nedaplatin group (three of four, 75%) was more frequent than the docetaxel and nedaplatin group (none of seven, P = 0.024). The objective response rate in eleven patients with measurable disease was 36% (complete response at 9% and partial response at 27%), and the disease control rate was 73% (stable disease at 36%). Conclusion: Nedaplatin-associated hypersensitivity reactions are not rare in patients who developed allergic reactions to carboplatin. Retreatment of carboplatin-allergic patients with nedaplatin cannot be recommended without careful consideration of the potential risks and benefits. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to clarify the factors affecting the outcome of induction of labor (IOL) in a Japanese population and to develop a prediction model to assess the probability of emergent cesarean section (CS). Material and Methods: By reviewing the medical records of 1029 women who underwent IOL, we compared the emergent CS rate during IOL among subgroups divided by parity and pre-labor risk, such as fetal anomaly and maternal complication. We created a prediction model to predict the CS rate during IOL focusing on 392 cases of nulliparous women with premature rupture of membrane (PROM). Six factors, including Bishop score (BS), gestational age, maternal body mass index (BMI), maternal height (MH) and birth weight (BW) were extracted and multivariable logistic regression analysis followed by cross-validation test were performed. Results: The emergent CS rate was remarkably higher in the nulliparous group than in the multiparous group (17.6% vs 2.0%). In the nulliparous group, the high-risk group demonstrated a higher CS rate than the low-risk group (33.8% vs 15.6%). Multivariate analysis on nulliparous low-risk cases with PROM demonstrated significant odds ratios for emergent CS in BS, MH and BW. Cross-validation test selected these three factors as the best combination of parameters. The prediction formula was determined as follows: probability of CS (%) = (odds/1 + odds) ∗ 100, odds = eX and X = 8.18 + 1.23 ∗ BW (kg) − 7.74 ∗ MH (m) − 0.253 ∗ BS. Conclusion: This study is the first to provide a prediction formula targeting an Asian population. Our model, which is specialized for nulliparous low-risk women could enable obstetricians to inform patients of the precise prospect of IOL outcome. [ABSTRACT FROM AUTHOR]
