    ABSTRACT: Uterine leiomyoma is the most common pelvic tumor in women, but the actual prevalence is unknown. To review the literature on the prevalence of uterine leiomyoma, presenting symptoms, and medical management. On April 1-30, 2014, a PubMed search for studies reported in English was conducted using the terms "uterine leiomyoma," "prevalence," and "symptoms." Another search was performed using the terms "uterine leiomyoma" and "treatment." All trial types other than internet-only studies were included. Animal studies were excluded from the prevalence/symptom review, but included in the medical management review. Prevalence rates were recorded on the basis of imaging modality, cohort studied, ethnic origin, and age. Studies involving asymptomatic women revealed a trend in prevalence similar to that in symptomatic women, and showed that leiomyomas are more common in this cohort than previously recognized. Affected patients can present with many complaints, but no single symptom has been shown to be specific for this tumor. Various medical therapies are reviewed, summarizing efficacy and toxicity. Further research needs to be conducted on the prevalence in asymptomatic women. Current and future medical management options provide promising results in symptom reduction. Copyright © 2015.

    ABSTRACT: To evaluate the feasibility and safety of robotic nerve-sparing radical hysterectomy for locally advanced cervical cancer (LACC). In a retrospective study, data were analyzed for patients treated for cervical cancer at a center in Beijing, China, between December 2011 and September 2013. Patients were subdivided into those with early-stage disease (FIGO stage IA2-IB1) who were treated by robotic surgery (group 1), and those with LACC (stage IB2-IIB) who were treated by robotic surgery after neoadjuvant chemotherapy (NACT; group 2). Therapeutic outcomes and complications were compared. Group 1 included 32 patients and group 2 included 22 patients. Two patients in group 2 did not respond to NACT and did not undergo surgery. The operative outcomes and incidences of complications did not differ significantly between the two groups (P>0.05 for all). There were no differences in nodal yield, lengths of parametrium removed, or vaginal cuff length (P>0.05 for all). During a mean follow-up of 26months, no patient experienced recurrence. Robotic nerve-sparing radical hysterectomy was found to be feasible and safe for LACC after NACT. A larger case series with longer follow-up data is needed to justify its widespread application.

    ABSTRACT: To determine the prevalence of and risk factors for bacterial vaginosis. A cross-sectional study of women aged 14-54 years attending 18 primary healthcare units in Botucatu, Brazil, for cervical screening was undertaken between September 1, 2012, and January 31, 2013. Data on sociodemographics, sexual behavior, and medical history were obtained by interview. Vaginal swabs were taken to classify the vaginal flora according to the Nugent scoring system. Candida sp. hyphae and infection by Trichomonas vaginalis were also evaluated by microscopy and culture, respectively. Stepwise logistic regression analysis was performed to identify risk factors independently associated with bacterial vaginosis. Among 1519 women included in analyses, 457 (30.1%) had bacterial vaginosis. Variables independently associated with bacterial vaginosis were a single marital status (OR 1.4; 95%CI 1.1-1.8), partner infidelity (OR 1.5; 95%CI 1.2-1.9), abnormal discharge in the previous year (OR 1.5; 95%CI 1.2-2.0), and concurrent trichomoniasis (OR 4.1; 95%CI 1.5-11.5). Current use of hormonal contraception (OR 0.7; 95%CI 0.5-0.9), luteal phase of menstrual cycle (OR 0.8; 95%CI 0.6-0.9), higher income (OR 0.8; 95%CI 0.6-0.9), and vaginal candidiasis (OR 0.5; 95%CI 0.3-0.9) all had protective effects. The prevalence of bacterial vaginosis in the study population is high. The epidemiological data provide evidence of the sexual transmissibility of bacterial vaginosis.

    ABSTRACT: To validate a simplified objective structured clinical examination (OSCE) tool for evaluating the competency of birth attendants in low-resource countries who have been trained in neonatal resuscitation by the Helping Babies Breathe (HBB) program. A prospective cross-sectional study of the OSCE tool was conducted among trained birth attendants working at dispensaries, health centers, or hospitals in five regions of Tanzania between October 1, 2013, and May 1, 2014. A 13-item checklist was used to assess clinical competency in a simulated newborn resuscitation scenario. The OSCE tool was simultaneously administered by HBB trainers and experienced external evaluators. Paired results were compared using the Cohen κ value to measure inter-rater reliability. Participant performance was rated by health cadre, region, and facility type. Inter-rater reliability was moderate (κ=0.41-0.60) or substantial (κ=0.61-0.80) for eight of the OSCE items; agreement was fair (κ=0.21-0.41) for the remaining five items. The best OSCE performances were recorded among nurses and providers from facilities with high annual birth volumes. The simplified OSCE tool could facilitate efficient implementation of national-level HBB programs. Limitations in inter-rater reliability might be improved through additional training.

    ABSTRACT: To determine women's perceptions and expectations of focused prenatal care visits. The present questionnaire-based, cross-sectional survey was performed among pregnant women in their third trimester attending two tertiary health centers in southern Nigeria between January and March 2012. Obstetric data, histories, and information on preferences for prenatal visits were obtained using questionnaires. A total of 353 questionnaires were appropriately completed. Among 277 participants who stated a preference for the number of prenatal care visits, 241 (87.0%) reported a preference of more than four. Among 203 parous women, 132 (65.0%) had no previous negative obstetric experience. Only previous stillbirth (odds ratio [OR] 2.67, 95% confidence interval [CI] 1.05-6.77; P=0.039) among multiparous women, and HIV/AIDS (OR 0.27, 95% CI 0.06-1.17; P=0.048) among all women were significantly associated with a preference for more prenatal visits. Previous negative obstetric experiences did not generally affect preference for prenatal visits. However, pregnant women expressed dissatisfaction with a reduced number of visits.

    ABSTRACT: To identify factors associated with cesarean delivery following successful external cephalic version (ECV). In a prospective study, data were obtained for ECV procedures performed at Cruces University Hospital, Spain, between March 2002 and June 2012. Women with a singleton pregnancy who had a successful, uncomplicated ECV and whose delivery was assisted at the study hospital, with the fetus in cephalic presentation, were included. A multivariate model of risk factors of cesarean delivery was developed. Among 627 women included, 92 (14.7%) delivered by cesarean. A cesarean was performed among 33 (8.5%) of 387 women with spontaneous labor versus 59 (24.6%) of 240 who were induced (P<0.001). Multivariate analysis showed that higher BMI (P=0.006), labor induction (P=0.001), and prior cesarean (P<0.001) were associated with cesarean. Time between ECV and delivery was inversely associated with probability of cesarean during the first 2weeks. Thus, the probabilities of cesarean delivery on the first day were 0.53 (95% CI 0.35-0.71) and 0.34 (95% CI 0.18-0.51) following induced and spontaneous labor, respectively. On the seventh day, the probabilities were 0.23 (95% CI 0.15-0.32) and 0.12 (95% CI 0.07-0.18), respectively. Following ECV, induction of labor, an interval of less than 2weeks to delivery, BMI, and previous cesarean were associated with an increased risk of cesarean.

    ABSTRACT: To analyze the relationship between contrast kinetics in tumorous vessels and lesion histologic type in an attempt to differentiate between malignant and benign disease. In a single-center prospective study, patients who had been referred for elective surgery because of a diagnosis of unilateral and/or bilateral adnexal masses were enrolled at Dr Jan Biziel University Hospital, Bydgoszcz, Poland, between January 2012 and September 2013. Participants underwent contrast-enhanced ultrasonography examination (CEUS). Contrast kinetics were obtained and compared with the neovascularization of the tumor. Accuracy, and positive and negative predictive values were calculated. Among 160 enrolled patients, 84 underwent CEUS examination and 51 lesions were studied. Baseline and maximum color Doppler intensities were significantly higher in malignant than in benign tumors (P<0.001 for both). Similarly, the absolute and relative increases in color Doppler intensity were significantly higher in malignant tumors (P<0.001). The estimated positive predictive value was 97.1%, the negative predictive value was 100%, and the accuracy was 100%. Peak enhanced intensity of fractional color Doppler Area and area under the time-intensity curve (S-parameter) correlated significantly with the histology of the lesion (P<0.001). Probability curves demonstrated that higher S-parameter values were correlated with a higher risk of malignancy. Transvaginal CEUS is a reliable and reproducible way to differentiate between benign and malignant adnexal lesions. Copyright © 2015 International Federation of Gynecology and Obstetrics.

    ABSTRACT: To determine the effect of aspirin and low-molecular-weight heparin (LMWH) for women affected by recurrent spontaneous abortion (RSA). The present prospective observational study included women with RSA (≥2 previous spontaneous abortions) and those without a history of RSA attending Ren Ji Hospital, Shanghai, China, between March 2011 and March 2014. D-dimer levels, auto-antibodies, and platelet aggregation in response to arachidonic acid (AA) and adenosine diphosphate (ADP) were monitored before pregnancy. Women with unexplained RSA and increased platelet aggregation received low-dose aspirin, and those with elevated D-dimer levels (>0.75μg/mL) received LMWH. Platelet aggregation in response to AA and ADP, and D-dimer levels were monitored during pregnancy. Among 517 participants with RSA, 325 had unexplained RSA. Compared with 63 control patients, those with unexplained RSA and two, three, four, or at least five previous spontaneous abortions had increased platelet aggregation in response to AA (P<0.05 for all comparisons) but not to ADP. Among 37 women with unexplained RSA who became pregnant, aspirin reduced platelet aggregation in response to AA (P<0.001). LMWH reduced D-dimer levels during pregnancy (P<0.001). Among 37 women with unexplained RSA who became pregnant and completed the study, 33 (89.2%) had a live birth. Aspirin and LMWH maintained a lower thrombotic state and led to a high live birth rate among patients with unexplained RSA. Copyright © 2015. Published by Elsevier Ireland Ltd.

    ABSTRACT: Metformin is used among patients with polycystic ovary syndrome (PCOS), but findings for its effects on outcomes of assisted reproductive technology (ART) have been conflicting. To compare ART outcomes among women with PCOS who were and were not given metformin. Databases were searched for reports published in English between 2002 and 2013, using combinations of the terms "polycystic ovary syndrome," "PCOS," "insulin-sensitizing," and "metformin." Randomized controlled trials of metformin versus placebo among women with PCOS undergoing ART were included if they assessed rates of pregnancy, live birth, spontaneous abortion, multiple pregnancy, and/or ovarian hyperstimulation syndrome (OHSS). Data were extracted from included studies. The Mantel-Haenzel random-effects model was used for meta-analyses. Twelve studies (1516 participants) were included. No significant differences were recorded between metformin and placebo groups for rates of pregnancy (risk ratio [RR] 1.11, 95% CI 0.92-1.33), live birth (RR 1.12, 0.92-1.36), spontaneous abortion (RR 1.00, 0.60-1.67), or multiple pregnancy (RR 0.96, 0.47-1.96). However, OHSS rate was significantly lower among patients who received metformin than among those who received placebo (RR 0.44, 0.26-0.77). Metformin does not improve ART outcomes among patients with PCOS, but does significantly reduce their risk of OHSS. Copyright © 2015 International Federation of Gynecology and Obstetrics.

    ABSTRACT: When patients require information to decide whether to accept recommended treatments, a question in both law and ethics is whether the same information is adequate whether they consent or refuse, or whether refusal requires more or repeated information. Refusals of recommended treatment can carry increased risks for patients' well-being and so require more emphatic disclosure without imposing pressure. A related question is whether guardians of dependents who would decline recommended treatment for themselves-for instance on religious grounds-can similarly decline it for their dependents. When pregnant women, children, and adolescents are able to give consent for recommended treatment, the question arises whether they are equally competent to refuse it and prevent their decisions being overridden by guardians or courts. Consenting to and refusing medical treatments recommended in one's own or dependents' best interests might not be the same sorts of decisions and could require different levels of disclosure and capacity.

    ABSTRACT: To characterize the incidence, presentation, management, and outcomes of rectovaginal fistula (RVF) in Ethiopia. In a retrospective study, demographic and clinical data were obtained for all women with genital tract fistulas admitted to the Barhirdar Hamlin Fistula Hospital, Ethiopia, for fistula repair surgery between January 2005 and October 2008. Of 1100 cases, 1057 were suitable for analysis. Vesicovaginal fistula (VVF) without RVF was present in 933 (88.3%) cases, combined VVF and RVF in 79 (7.5%), and isolated RVF in 45 (4.3%). Only 4 (0.4%) women had isolated RVFs that could be attributed to prolonged obstructed labor; the remaining 41 RVFs were due to trauma (including sexual trauma), iatrogenic causes, infection, perineal tears, or previous failed repairs. All RVFs were managed with a flap-splitting operative technique, without grafts or diverting colostomies. Overall, 120 (98.4%) of 122 RVFs repaired at the study hospital remained closed at discharge. Combined VVF and RVF was associated with a longer labor (P<0.001), more stillbirths (P=0.028), a larger and lower VVF (P<0.001 for both), and more vaginal scarring than was isolated VVF (P<0.001). An obstetric RVF represents a more severe injury process than does a VVF. RVFs rarely occur without a VVF if due to obstructed labor. However, they can be managed successfully without diverting colostomies or grafts. Copyright © 2015 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

    ABSTRACT: To compare the artesunate-amodiaquine and artemether-lumefantrine combinations in the treatment of acute uncomplicated falciparum malaria during pregnancy. Between January and July, 2013, a double-blind randomized trial was undertaken of symptomatic pregnant women (second/third trimester) with malaria parasitemia who attended a center in Ile-Ife, Nigeria. Participants were assigned to receive artesunate-amodiaquine or artemether-lumefantrine (twice daily on days 1-3) according to a computer-generated randomization sequence. Participants and investigators were masked to group allocation. Clinical evaluations and malaria parasite counts were performed at baseline and on days 2, 3, 7, and 28. Mean interval to symptomatic relief, day-3 parasite clearance, day-28 cure rate, and adverse effects were assessed. Of 75 women assigned to each group, 65 in the artesunate-amodiaquine group and 71 in the artemether-lumefantrine group completed the study. No significant differences between the artesunate-amodiaquine and artemether-lumefantrine groups were recorded for mean interval to symptomatic relief (2.2±1.0days vs 2.0±0.8days; P=0.090), day-3 parasite clearance (58/65 [89.2%] vs 66/71 [93.0%]; P=0.444), and day-28 cure rate (64/65 [98.5%] vs 67/71 [94.4%]; P=0.138). Adverse effects (body weakness and pruritus) were more common among women assigned to artesunate-amodiaquine (30/75 [40.0%]) than among those assigned to artemether-lumefantrine (2/75 [2.7%]; P<0.001). Efficacies of the regimens are similar among pregnant women. However, adverse effects are more common with artesunate-amodiaquine. Pan-African Clinical Trial Registry: PACTR201310000484185.

    ABSTRACT: To investigate the use and success rate of hysteroscopic tubal electrocoagulation for the treatment of hydrosalpinx-related infertility among patients undergoing in vitro fertilization (IVF) who have laparoscopic contraindications. A prospective study was conducted among patients who had unilateral or bilateral hydrosalpinges identified on hysterosalpingography and vaginal ultrasonography, and who were undergoing IVF at a center in Cairo, Egypt, between January 1, 2013, and October 30, 2014. All patients who had contraindications for laparoscopy were scheduled for hysteroscopic tubal electrocoagulation (group 1); the other patients underwent laparoscopic tubal ligation (group 2). For all patients, hysterosalpingography was performed 3 months after their procedure to evaluate proximal tubal occlusion. Among 85 enrolled patients, 22 underwent hysteroscopic tubal electrocoagulation and 63 underwent laparoscopic tubal ligation. The procedure was successful in terms of tubal occlusion for 25 (93%) of 27 hydrosalpinges in group 1, and 78 (96%) of 81 hydrosalpinges in group 2 (P=0.597). No intraoperative or postoperative complications were reported. Hysteroscopic tubal electrocoagulation was found to be a successful treatment for hydrosalpinges before IVF when laparoscopy is contraindicated.

    ABSTRACT: To compare the effectiveness of fluoxetine and gabapentin for treatment of vasomotor symptoms (VMS) after the menopause. Between March 2011 and March 2012, a randomized crossover study was performed at a center in Semnan, Iran, among postmenopausal women aged 45-57years with hot flashes (≥2 per day for previous 4months) for which they had received no previous treatment. Participants were divided into two groups with consecutive numbers assigned in order of recruitment. In the first treatment round (4weeks), group A received 20mg/day fluoxetine and group B received 300mg/day gabapentin. After a 2-week washout period, group A received gabapentin and group B received fluoxetine in a second round (4weeks). Information about VMS was obtained with the Greene Climacteric Scale questionnaire. Participants and all investigators except one were masked to group assignment. Data for 79 participants (39 in group A, 40 in group B) were analyzed. In both treatment rounds, gabapentin caused greater reductions in the severity of hot flashes than did fluoxetine (P<0.001 for both). After the first round of treatment, those who had received gabapentin reported greater reductions in the severity of night sweats (P<0.001). Gabapentin at a dose of 300mg/day is more effective for treatment of VMS among postmenopausal women than is 20mg/day fluoxetine. Iranian Registry of Clinical Trials:IRCT2014092711019N3.

    ABSTRACT: To assess Doppler flow velocity in fetal, uteroplacental, and maternal arteries before and after betamethasone therapy among singleton pregnancies complicated by fetal growth restriction (FGR). A prospective, longitudinal, multicenter study was conducted at three university-affiliated hospitals in Tehran, Iran, between January 1 and November 30, 2013. The inclusion criteria were FGR, a gestational age of 24-34weeks, no fetal anomalies, and no previous betamethasone therapy. Doppler blood flow was measured in uterine, umbilical, and middle cerebral arteries before treatment, and 24hours and 5days after completion of betamethasone therapy (two 12-mg doses at a 24-hour interval). Overall, 40 women were enrolled. Doppler blood flow through the uterine and umbilical arteries showed significant but transient changes across the three timepoints (P<0.001), whereas the middle cerebral artery showed no changes. Prenatal betamethasone led to transient improvements in blood flow in the uterine and umbilical arteries among pregnancies affected by FGR.
