    ABSTRACT: Ulipristal Acetate (UPA) modifies the endometrium, as well as fibroids, and therefore it might make hysteroscopic surgery more difficult. To confirm that pre-treatment with UPA is as safe and effective an option as pre-treatment with GnRH analogues, considered the gold standard. We present the first series of 26 hysteroscopic myomectomies after 3 months treatment with UPA and we compare the results with a series of 24 cases pretreated with GnRH analogues. This was a retrospective cohort study between July 2013 and May 2015. We analyszed patients with submucous myomas >2.5 in diameter. Hysteroscopic myomectomy was performed after 3 months of treatment with either UPA (5mg daily) or the GnRH agonist (3.75mg/month). Both groups were similar in age, myoma initial size and classification. There were no significant differences between UPA and GnRHa treated groups in terms of percentage of myomas resected (39% vs 98%), duration of surgery (38 vs 37min), fluid deficit (200 vs 350ml) and complications. In the surgeon's subjective opinion, UPA treatment was associated with an easier resection. Based on our experience, previous treatment with UPA does not difficult Hhysteroscopic myomectomy. Endometrial changes have no impact on surgery. Safety and feasibility are comparable to hysteroscopic myomectomies with previous treatment with GnRH analogues. This allows us to take advantage of the reduction in size of fibroids before surgery with less side effects.

    ABSTRACT: Objective: To evaluate the sonologic and clinical outcome of collagen coated (CC) versus non-collagen coated (NC) anterior vaginal mesh (AVM) for pelvic organ prolapse (POP) surgery. Study design: The study is a prospective observational study which included 122 patients who had symptomatic POP stage III and IV. AvaultaPlus™ (collagen coated, CC group) was compared to Perigee™ (non collagen coated, NC group). Introital ultrasound morphology, measure of neovascularization by color Doppler and clinical outcomes were assessed. Student t test was used for comparison of pre- and post-operation continuous data (p value of <0.05). Results: A total of 110 (CC group=50, NC group=60) women completed the study. A woman in the CC group developed ureteral injury. Both groups had comparable morphologic and clinical outcomes however, the onset of changes in mesh thickness and neovascularization occurred earlier in the NC group (1 month) compared to the CC group (6 months to 1 year). Conclusion: CC group was comparable to the NC group in terms of erosion rate, ultrasound and clinical assessment. Collagen coating may induce delayed inflammatory response however may also delay tissue integration. The onset of changes in mesh thickness and neovascularization may give us an insight toward utilization of collagen coated mesh for host-tissue integration.

    ABSTRACT: Functional hypothalamic amenorrhoea (FHA) is a neuroendocrine disorder caused by an energy deficit and characterized by low leptin levels. Based on this, previous studies have suggested that leptin administration may play a crucial role in FHA treatment. However, FHA is also associated with abnormal psychosocial and dietary behaviour that needs to be addressed. In this context, this systematic review examined the efficacy of leptin treatment, non-pharmacological therapy and nutritional interventions in FHA. PubMed, Medline and Cochrane Library databases were searched in order to find relevant papers, including randomized controlled trials, clinical trials, prospective studies and case reports. The effects of different treatments on reproductive function, hormonal status and bone markers were recorded. Studies regarding other forms of treatment were excluded. In total, 111 papers were retrieved. After the removal of 29 duplicate papers, the abstracts and titles of 82 papers were examined. Subsequently, 53 papers were excluded based on title, and seven papers were omitted based on abstract. The remaining 11 papers were used: three based on leptin treatment, three regarding non-pharmacological treatment and five regarding dietary intervention. This literature review indicates that all of these treatment strategies improved reproductive function and hormonal status significantly, although conclusive results could not be drawn on bone markers. While leptin may be a promising new treatment, social aspects of FHA should also be addressed. As a result, a multifaceted therapeutic approach should be applied to treat affected women.

    ABSTRACT: Objective: To investigate the effect of dehydroepiandrosterone (DHEA) on mouse decidual endometrial stromal cells (ESCs) and to explore mechanisms regulating endometrial receptivity. Study design: Mouse ESCs were incubated with increasing concentrations of DHEA during decidualization. Treatment with flutamide (FLU), a specific androgen receptor (AR) antagonist, was also performed. Flow cytometry was used to measure intracellular reactive oxygen species (ROS). Real time-PCR was used to determine mRNA expression of decidual PRL-related protein (dPRP), AR, and HomeoboxA10 (HOXA10). Protein levels of AR and HOXA10 were measured by western blot. Results: DHEA significantly inhibited ESC proliferation at concentrations ≥1×10(-6)M. DHEA treatment reduced intracellular ROS in a dose-dependent manner. Expression of dPRP was minimally affected by DHEA at concentrations of 1 to 100nM. However, DHEA (100nM) significantly increased the expression of HOXA10 at both the mRNA and protein levels (P<0.01). Importantly, this DHEA-mediated increase in HOXA10 was attenuated by treatment with FLU. Finally, neither DHEA nor FLU influenced expression of AR mRNA or protein. Conclusion: Low concentration of DHEA improves the antioxidant capacity of decidual ESCs. DHEA treatment may also improve endometrium receptivity via AR.

    ABSTRACT: Objective: To compare the efficacy of calcium supplements versus combined oral contraceptive pills (COC) containing drospirenone in treating mild to moderate premenstrual syndrome. Study design: This was a double-blind, randomized placebo controlled trial conducted in Beni-Suef University Hospital. Premenstrual syndrome (PMS) was prospectively diagnosed using the Daily Record of Severity of Problems (DRSP). In total, 210 women with mild to moderate PMS were randomly divided into three equal groups. Group 1 received COC daily for 21 days starting on the third day of menstruation and a daily oral placebo similar to calcium and vitamin D. Group 2 received calcium 400mg+vitamin D 400IU once daily and an oral placebo similar to COC for 21 days starting on the third day of menstruation. Group 3 received a daily placebo similar to calcium and vitamin D in addition to an oral placebo similar to COC for 21 days starting on the third day of menstruation. Treatment was continued for 3 months. Results: The proportion of women with improved PMS decreased progressively from the COC group to the calcium group and the placebo group (81%, 62.3% and 16.3%, respectively; p<0.001). Similarly, mean DRSP scores 5 days before menstruation decreased progressively from the COC group, the calcium group and the placebo group (45.51±16.97, 55±15.71 and 74.98±19.12, respectively; p<0.001). Conclusion: Both COC and calcium supplements improved DRSP scores in women with mild to moderate PMS, but the improvement was more evident with COC.

    ABSTRACT: Objective: Although placement of a retropubic mid-urethral slings (MUS) is one of the gold standard surgical treatments for stress urinary incontinence, new devices are poorly evaluated before marketing. We compared TVT-EXACT™ (TVT-E), a new device expected to reduce bladder injuries, with the historically described bottom-to-top TVT™ (TVT). Study design: This retrospective study compared TVT-E (n=49) and TVT (n=49). The main outcomes were the prevalence of complications (bladder injuries, immediate postoperative pain, perioperative complications, etc.) and the short-term success rate (no reported urinary leakage and negative cough test) of both MUSs. Results: Minimum follow-up was 12 months. The characteristics of the two groups were comparable. The prevalence of bladder injury for TVT-E and TVT was 8% and 6%, respectively (p=1). The intensity of immediate postoperative pain (VAS/100) was lower following TVT-E than after TVT (8.0 vs. 15.9, p=0.01). The first post-void residual was increased in the TVT-E group (153.9 vs. 78.9mL, p=0.045), and there were more postoperative bladder outlet obstruction (BOO) symptoms in the TVT-E group (24% vs. 6%, p=0.02). However, there was no difference when considering only de novo BOO (14% vs. 4%, p=0.16). The prevalence of peri- and post-operative complications was equal in the two groups. The success rate was similar at 12 months of follow-up (80 vs. 82%, p=1). Conclusion: The prevalence of bladder injury was unchanged with TVT-EXACT™ compared with TVT™, but post-operative pain was decreased. The success rate of both retropubic MUSs was similar at 12 months of follow-up.

    ABSTRACT: Objective: This study examined microRNA-92 (miR-92) expression level in relation to the mRNA level of its potential target gene, estrogen receptor β1 (ERβ1), in female patients diagnosed with pelvic organ prolapse (POP). Study design: Between July 2012 and September 2014, a total of 104 patients were recruited at the First Affiliated Hospital of Sun Yet-sen University, which included 56 POP patients and 48 non-POP control subjects. Based on POP-Q score, the POP patients were further categorized into POP II and POP III groups. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to quantify miR-92 expression level. ERβ1 tissue expression was measured by western blot and immunohistochemistry (IHC) methods. SPSS 19.0 software was used for statistical analysis. Results: No remarkable differences were observed between the POP group and non-POP group, and between the POP II and POP III groups, with respect to age, body mass index (BMI), parity, menopause status, and family history of POP. The expression level of miR-92 in the POP group was dramatically higher than the non-POP group (P<0.05). Consistent with the disease status, miR-92 expression level in POP III group was markedly higher than the POP II group (P<0.05). Western blot analysis revealed significantly reduced levels of ERβ1 in the POP group compared to the non-POP group, with similar results obtained between the POP III and POP II groups (all P<0.05). IHC results showed ERβ1 staining mainly in the nucleus and semi-quantitative measurements, expressed as positive expression rate, revealed that ERβ1 level in the POP group was clearly lower than non-POP group. Finally, statistical analysis of IHC results from uterosacral ligament tissue showed inverse correlation between miR-92 and ERβ1 expression levels in POP patients (P<0.05). Conclusions: Our results revealed increased miR-92 expression and decreased ERβ1 level in uterosacral ligaments of women diagnosed with POP, compared to non-POP subjects POP III patients exhibited more severe changes than POP II patients. Further, ERβ1expression is inversely correlated to miR-92 expression. Taken together, our results suggest that miR-92 and ERβ1 expression levels may be used as reliable diagnostic markers for assessing the severity of POP.

    ABSTRACT: Objective: The impact of simple and radical hysterectomy on all aspects of pelvic floor dysfunctions was evaluated in current study. Study design: This retrospective cohort study included 142 patients; 58 women (40.8%) who have undergone simple, 41 (28.8%) radical hysterectomy, and 43 (30.2%) women without any surgical intervention to serve as the control group. The validated versions of the Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire (IIQ-7), Pelvic Floor and Incontinence Sexual Impact Questionnaire (PISQ-12), Wexner Incontinence Scale score and pelvic organ prolapse quantification (POP-Q) system were used in detailed evaluation of pelvic floor dysfunction. One-way ANOVA and Pearson's chi square tests were performed in statistical analysis. Results: It was found that there were significant differences in irritative and obstructive scores of UDI-6 between Type III hysterectomy group and Type I hysterectomy group. In addition, patients of Type I hysterectomy had significant higher irritative and obstructive scores than the control group. Type III hysterectomy had the most significant deteriorating effect on sexual life, based on scores of PISQ-12 compared to both Type I hysterectomy group and control group. Conclusion: Hysterectomy results in detrimental effects on the quality of life (QoL) regarding all aspects of pelvic floor functions especially in women of radical hysterectomy. Urinary dysfunctional symptoms like urgency, obstruction and especially sexual problems are more bothersome and difficult to overcome. The impact of hysterectomy on QoL should be investigated as a whole and may be more profound than previously thought.

    ABSTRACT: Objectives: Our aim was to determine serum perforin and granzyme-B levels in adolescent PCOS patients, and to investigate whether they are associated with some of the insulin sensitivity, obesity and cardiovascular (CV) risk markers and metabolic syndrome. Study design: A case-control study was carried out including a total of 172 adolescents (83 PCOS patients and 89 age-matched healthy controls). Participants were recruited consecutively. Homeostasis model assessment (HOMA-IR), lipid parameters, and anthropometric measurements were determined. Serum perforin and granzyme B levels were measured by commercially available ELISA kits. HOMA-IR>3.16 was considered to indicate the presence of insulin resistance. Logistic regression analysis was applied for the predictive value of granzyme-B for increased CV risk in PCOS patients. Results: As body mass index (BMI) of the PCOS patients was significantly higher than the controls (median 24.6kg/m(2) and 21.4kg/m(2), respectively, p<0.001) all parameters were evaluated after adjustment for BMI. Adolescents with PCOS had significantly higher levels of fasting glucose, insulin, HOMA-IR and granzyme-B when compared with controls. According to the results of logistic regression analysis, granzyme-B levels were found to be significantly associated with increased HOMA-IR (OR=6.120, 95% CI: 2.352-15.926, p<0.001) in adolescent PCOS patients. Additionally, elevated levels of serum granzyme-B were predictive for increased CV risk in PCOS patients (OR=0.237, 95% CI: 0.091-0.616, p=0.003). Conclusions: Increased levels of serum granzyme-B are independently associated with insulin resistance and also with increased CV risk in adolescent polycystic ovary syndrome patients.

    ABSTRACT: Objectives: To assess the effects of heavy metal and trace element concentrations in blood and follicular fluid on assisted reproductive technology cycle outcome. Study design: A prospective study was conducted between January 2012 and July 2012 in a university hospital infertility clinic. One hundred and one patients with unexplained infertility who underwent intracytoplasmic sperm injection using GnRH-antagonist protocol were recruited. Concentrations of four toxic metals (Cd, Pb, Hg, As) and three trace elements (Cu, Zn, Fe) were measured both in blood and follicular fluid specimens. Patients were evaluated in two groups; the study group consisted of patients with ongoing pregnancy (n=20) and the reference group consisted of patients experienced assisted reproductive technology failure, miscarriage or biochemical pregnancy (n=81). Results: Demographics and cycle parameters were comparable between the groups except for median number of day 3 Grade A embryos. Statistically significant negative correlations were found between blood Pb levels and number of MII oocytes, implantation, clinical pregnancy and ongoing pregnancy rates. Results of the log binomial regression revealed 2.2% lower risk for ongoing pregnancy for each 1μg/dL higher blood Pb concentration while holding the other variables in the model constant (RR 0.978; 95% CI 0.956-0.998; P=.041). Also, the results revealed 71.9% lower risk for ongoing pregnancy for each 1μg/dL higher follicular fluid Cu concentration while holding the other variables in the model constant (RR 0.288; 95% CI 0.085-0.92; P=.039). Conclusion: Blood concentrations of Pb and follicular fluid concentrations of Cu seem to have significant impacts on assisted reproductive technology cycle outcome.

    ABSTRACT: Objective: To investigate the significance of the related indexes of three-dimensional color power angiography (3D-CPA) combined with SonoVue angiography in the diagnosis and prognosis evaluation of intrauterine adhesion (IUA). Methods: The accuracy, sensitivity, and specificity were evaluated between 3D-TVS and hysteroscopy. Endometrial thickness, volume (V), mean gray value (MG), vascularization index (VI), flow index (FI), vascularization flow index (VFI), and other related indexes before and after the angiography were compared. According to the hysteroscopy findings, the patients were divided into three groups: mild, medium, and severe. The endometrial thickness at 3 months postoperatively and the pregnancy rates at 1 year postoperatively were compared. Results: Compared with the hysteroscopy, sensitivity: 0.970 (0.021), specificity: 0.667 (0.086), (the values inside the bracket were the standard error), positive likelihood ratio: 2.909, negative likelihood ratio: 0.045. There was a significant difference in endometrial thickness and V between the three groups (P<0.05), and there was a significant difference in MG, VI, FI, and VFI between the mild and severe group (P>0.05). During intravenous injection of SonoVue, the blood flow of each group increased (P<0.001), and the VI, FI, and VFI of each group were significantly different (P<0.05). Compared with the preoperative values, the endometrial thickness, V, MG, VI, FI, and VFI significantly changed at 3 months postoperatively (P<0.05). The mild group and high VI group had a higher pregnancy success rate at one year postoperatively. Conclusion: 3D-CPA can indirectly diagnose IUA, and may play an important role in prognosis assessment.

    ABSTRACT: Introduction: The lung-to-head ratio (LHR) is routinely used to select the best candidates for prenatal surgery and to follow-up the fetuses with congenital diaphragmatic hernia (CDH). Since this index is gestation-dependent, the quantitative lung index (QLI) was proposed as an alternative parameter that stays constant throughout pregnancy. Our objective was to study the performance of QLI to predict survival in fetuses with CDH. Materials and methods: Observational retrospective study of fetuses with isolated CDH, referred to our center. LHR was originally used for the prenatal surgery evaluation. We calculated the QLI and compared the performance of both indexes (QLI and LHR) to predict survival. Results: From January-2009 to February-2015 we followed 31 fetuses with isolated CDH. The mean QLI was 0.66 (95% CI: 0.57-0.75) for survivors and 0.41 (95% CI: 0.25-0.58) for non-survivors (p<0.01) and the mean LHR was 1.38 (95% CI: 1.17-1.60) for survivors and 0.91 (95% CI: 0.57-1.25) for non-survivors (p<0.02). All operated fetuses (n=12) had a LHR <1 and a QLI <0.5 and none of them survived when the QLI was <0.32. When separately considering the prenatal surgery status, the mean values of the QLI (but not those of the LHR) were still significantly different between survivors and non-survivors. The comparative ROC curves showed a better performance of the QLI with respect to the LHR for the prediction of survival, especially in the group of operated fetuses, although differences were not statistically significant. Comment: The QLI seems to be a better predictor for survival than the LHR, especially for the group of fetuses undergoing prenatal surgery.

    ABSTRACT: Introduction: Planned cesarean hysterectomy (CH) is recommended to minimize morbidity for suspected placenta accreta (PA), yet this ends fertility. We examined CH frequency and post-operative morbidities for suspected PA cases when an intra-operative decision strategy to perform CH was used. Methods: Suspected PA cases were pre-operatively identified in one tertiary care center. Women were assessed intra-operatively, prior to uterine incision, for immediate CH or for attempted placental separation. We compared outcomes among women with versus without PA (surgical and/or pathologic diagnosis), and examined outcomes following immediate CH versus attempted placental separation. Results: Our cohort, from 2002 to 2012, comprised 99 women with suspected PA; 54 (54.5%) had PA diagnosed by surgery/pathology, and 45 (45.5%) did not. Among women diagnoses surgically or pathologically with PA, CH was performed for 46/54 (85%); 8 women with suspected PA had successful placental separation. 27 of the 46 CH were performed immediately following uterine wall examination and 19 were performed following attempted placental separation. We received histological confirmation of the clinical placenta accreta diagnosis for 24/46 (52.2%) cases, and in 22/46 (47.8%) cases the histology did not confirm the clinical diagnosis. Surgery duration, packed cell transfusion requirement and postoperative outcomes were similar among women with PA regardless of immediate CH versus attempted placental separation, except for a higher cystotomy rates following attempted placental separation. Emergency deliveries were performed at significantly earlier gestational ages. Discussion: Among women with suspected PA, an intra-operative CH decision allows some women to avoid CH. Consideration of attempted placental separation did not increase blood transfusion or post-operative complications, but was associated with a higher rate of cystotomy.
