  • Three-dimensional ultrasound in the diagnosis and the classification of
           congenital uterine anomalies using the ESHRE/ESGE classification: a
           diagnostic accuracy study
    • Authors: Anna Kougioumtsidou; Themistoklis Mikos; Grigoris F. Grimbizis; Aikaterini Karavida; Theodoros D. Theodoridis; Alexandros Sotiriadis; Basil C. Tarlatzis; Apostolos P. Athanasiadis
      Abstract: Study objective To estimate the diagnostic accuracy of three-dimensional ultrasonography (3D US) compared to hysteroscopy/laparoscopy, in the investigation of uterine congenital anomalies using the ESHRE/ESGE classification of female genital tract congenital anomalies. Design Prospective blind, comparative, cohort study. Setting University Tertiary Hospital and affiliated private Hospital. Patients and methods Sixty-two women consecutively referred with a suspected diagnosis of uterine congenital anomalies. The ESHRE/ESGE classification of congenital anomalies of the female genital tract was used for the description of abnormal findings. Interventions All patients underwent (1) 3D US and (2) hysteroscopy with laparoscopy to establish the final diagnosis. Results Concordance between 3D US and hysteroscopy with laparoscopy about the type and the classification of uterine anomaly was verified in 61 cases, including all those with septate uterus, dysmorphic uterus, bicorporeal, hemi-uterus or unicorporeal, and aplastic uterus and one out of two with normal uterus. For the diagnosis of septate uteri, which was the most common anomaly, the sensitivity of 3D US was 100%, the specificity was 92.3%, the PPV was 98% and the NPV was 100%, with kappa index 0.950. For bicorporeal, dysmorphic uterus, hemi-uteri or unicorporeal and aplastic uterus the sensitivity, specificity, PPV and NPV were all 100% with K = 1.00. Overall, 3D US showed perfect diagnostic accuracy (Kappa index = 0.945) in the detection of congenital uterine anomalies. Conclusion 3D US appears to be a very accurate method for the diagnosis of congenital uterine anomalies.

  • Effect of endometrial injury on in vitro fertilization pregnancy rates: a
           randomized, multicentre study
    • Authors: Jennifer Hilton; Kimberly E. Liu; Carl A. Laskin; Jon Havelock
      Abstract: Purpose To determine if endometrial injury prior to the first or second in vitro fertilization (IVF) cycle affects clinical pregnancy rates. Methods This study was a randomized, multicentre, controlled study performed at three Canadian outpatient fertility clinics. Patients undergoing their first or second IVF cycle were randomized to a single endometrial injury 5–10 days prior to the start of gonadotropins in an IVF cycle compared to no injury. The primary outcome was clinical pregnancy rate. Secondary outcomes were live birth rates, implantation rate, endometrial thickness, number of oocytes retrieved and the rate of embryo cryopreservation. Results Fifty-one women were randomized (25 in the en dometrial injury group and 26 in the control group); however, the study was terminated prematurely due to slow recruitment (target 332 patients). Groups were similar at baseline for: age, duration of infertility, BMI, day 3 FSH, and the number having first IVF cycle. The groups were similar for gonadotropin dose, endometrial thickness, number of oocytes retrieved, and embryo cryopreservation rate. The clinical pregnancy rate in the endometrial injury group was 52% (13/25) and 46% (12/26) in the control group (p = 0.45). Live birth rate in the endometrial injury group was 52% (13/25) and 35% (9/26) in the control group (p = 0.17). The implantation rate was also similar (58% vs. 45%, p = 0.17). Conclusions This study did not detect a difference in implantation, clinical pregnancy or live birth rates; however, the lack of difference in this study may be because it was underpowered.

  • Intrauterine administration of human chorionic gonadotropin improves the
           live birth rates of patients with repeated implantation failure in
           frozen-thawed blastocyst transfer cycles by increasing the percentage of
           peripheral regulatory T cells

      Abstract: Introduction Repeated implantation failure (RIF) frustrates both patients and their clinicians. Our aim was to observe the effects of intrauterine administration of human chorionic gonadotropin (hCG) on pregnancy outcomes of patients who received frozen-thawed embryo transfer (FET). Methods A prospective cohort study was conducted to evaluate the impact of intrauterine administration of hCG on pregnancy outcomes in FET cycles of patients with RIF from January 1st 2016 to December 31st 2016. The treatment group (n = 153, 152 cycles) received an infusion of 500 IU of hCG diluted in normal saline 3 days before embryo transfer. The control group (n = 152, 151 cycles) received embryo transfer with a previous intrauterine injection of normal saline without hCG. Early morning fasting blood samples were obtained from each patient for the measurement of peripheral regulatory T cells (Tregs) on the day of embryo transfer. The outcome parameters including Tregs in each group were compared. Results The patients in the hCG-treated group had significantly higher clinical pregnancy rates, implantation rates and live birth rates than the controls (37.5% versus 25.17%, 29.19% versus 19.4%, 26.97% versus 17.22%, respectively). They also had significantly higher percentages of peripheral Tregs than the controls (6.1 ± 0.6% versus 5.4 ± 1.0%). In addition, the clinical pregnancy rate, implantation rate and live birth rate in patients who received blastocyst transfer were significantly higher in the hCG-treated group when compared to the control group (41.38% versus 26.44%, 42.22% versus 26.14%, 33.33% versus 17.24%, respectively). We also showed that the clinical pregnancy rate, implantation rate and live birth rate were significantly higher in hCG-treated group when compared to the control group (49.12% versus 28.07%, 49.15% versus 28.07%, 40.35% versus 17.54%, respectively) of RIF patients with blastocyst transfer under 35 years, while there was on difference in patients above 35 years. Conclusions Intrauterine administration of hCG significantly improves the clinical pregnancy rate, implantation rate and live birth rate in FET cycles of patients with RIF by increasing Tregs. The treatment improves the pregnancy outcomes much more for younger RIF patients transferred blastocysts.

  • Oncoplastic breast-conserving surgery: More relevant than ever'
           Results of a survey among breast surgeons
    • Authors: Joerg Heil; Fabian Riedel; Christine Solbach; Bernd Gerber; Mario Marx; Sara Brucker; Christoph Heitmann; Jürgen Hoffmann; Markus Wallwiener; Michael P. Lux; Diethelm Wallwiener; Markus Hahn
      Abstract: Purpose Oncoplastic breast-conserving surgery has been part of clinical routine for several years without an internationally accepted nomenclature, standardization or a systematic evaluation of single surgical procedures. Methods We carried out a structured survey of breast surgeons (n = 50) during the annual meeting of the German Society for Senology in Berlin 2017. In the run-up to the event, 10 questions were determined and released for an anonymous survey during the consensus meeting. Results Most surgeons participating in the consensus meeting had an expertise of more than 200 oncologic breast surgeries in the last 3 years and approved the need of a higher rate of standardization in oncoplastic techniques. From the oncological standpoint, oncoplastic surgery is considered safe with a comparable rate of compilations as seen in conventional breast-conserving procedures. Most surgeons approve that using oncoplastic surgery, higher rates of breast conservation and improved aesthetic results can be accomplished. The majority of the participants would endorse a more systematic review of subjective aesthetic results in clinical routine. Conclusions A higher degree in standardization of oncoplastic breast surgery is required for surgical-technical, educational, and scientific reasons as well as for a more differentiated monetary compensation of the surgical procedures. This process has already been started.

  • Prevalence of colonisation by group B streptococcus in pregnant patients
           in Taguatinga, Federal District, Brazil: a cross-sectional study
    • Authors: Fábio Siqueira; Eli Mendes Ferreira; Iracema de Matos Calderon; Adriano Dias
      Abstract: Propose Group B streptococcus is responsible for severe infections in neonates resulting from vertical transmission from pregnant women colonized in the anal, perineal or vaginal regions. The identification of colonized patients and use of intrapartum prophylaxis may reduce the risk of neonatal infection. Methods A cross-sectional study of pregnant women of gestational age between 35 and 37 weeks was conducted. Material was collected from patients for laboratory identification of group B streptococcus. Epidemiological data, including weight, height, body mass index, antibiotic use during pregnancy, pathologies during pregnancy (diabetes, hypertensive diseases, and hypothyroidism), twinning, and others, were also collected from patients. Results The sample consisted of 501 pregnant women, and the prevalence of group B streptococcus was 14%. The mean age was 29 years, and the mean BMI was 30.7. During pregnancy, 204 patients had some type of infection, and 201 used antibiotics. Ninety-five patients were diagnosed with gestational diabetes mellitus and 74 with some type of hypertensive disease. Conclusions The prevalence of group B streptococcus observed did not differ from that observed in other studies. None of the factors studied can be considered as risk or protective factors for maternal colonization by group B streptococcus.

  • Delayed cord clamping does not affect umbilical cord blood gas analysis
    • Authors: Jiachen Tang; Rachel Fullarton; Sheri-Lee Samson; Yu Chen
      Abstract: Background Although delayed umbilical cord clamping has been shown to have significant benefits for both term and preterm infants, currently, data on its impact on blood gas analysis have been scant and conflicting. Methods In a retrospective review, we compared the demographic characteristics and blood gas parameters of 114 delayed cord clamping (DCC—births between 45 and 90 s in length; 109 being for 60 s) versus 407 early cord clamping births (ECC—immediately after delivery) collected over a 1-year period. Intrapartum care and timing of cord clamping for individual cases were performed at the discretion of obstetricians. The differences were assessed for statistical and clinical significance. Results The DCC group was found to have significantly higher mean Apgar scores at both 1 and 5 min (p < 0.05), as well as lower percentages of nulliparous births, cesarean-section deliveries, epidural anesthesia usage, and major pregnancy-related complications. No significant differences in maternal age, gestational age, neonate birthweight, sex, or in the presence of meconium at birth were observed. A higher umbilical artery pO2 in the DCC group [21 (9) vs. 19 (10) mmHg, p < 0.05] was the only statistically significant difference found out of all the blood gas parameters analyzed. Conclusions In this study, infants selected for the DCC procedure were found to be overall lower risk than those delivered as per the standard ECC procedure. No clinically significant difference in any blood gas parameter was observed, and therefore, no adjustment to clinical reference intervals is needed for DCC blood gas samples taken after a 1-min delay period.

  • Prolapse surgery versus vaginal pessary in women with symptomatic pelvic
           organ prolapse: which factors influence the choice of treatment'
    • Authors: Barbara Bodner-Adler; Klaus Bodner; Anna Stinglmeier; Oliver Kimberger; Ksenia Halpern; Heinz Koelbl; Wolfgang Umek
      Abstract: Objective To investigate which specific clinical factors influence patients’ choice of prolapse treatment. Methods This study includes a total of 510 cases with symptomatic pelvic organ prolapse (POP) of stage II or higher requiring prolapse treatment. Patients were divided into surgery and pessary groups according to their own choice and treatment preference. Primary outcome of interest was to define potential clinical parameters, which contribute to surgical treatment decision. Results A total of 252/510 (49%) women decided for prolapse surgery and 258/510 (51%) cases were treated conservatively with vaginal pessary. Hypertension, COPD as well as polypharmacy were parameters, which were statistically significantly more common in the pessary group compared to the surgically managed cases (p <0.05). On the contrary, women undergoing prolapse surgery were significantly younger and showed more advanced POP-Q (pelvic organ prolapse quantification) stages (p < 0.05). Clinical factors, such as BMI (body mass index), parity, mode of delivery and postmenopausal status, did not differ between the two groups (p > 0.05). Multiple logistic regression analysis revealed that advanced POP-Q stage (p < 0.001) as well as the absence of smoking (p < 0.001) were independent factors associated with surgical treatment decision. Conclusion Women, who favoured prolapse surgery, were younger and in significant better health condition (less hypertension and COPD), but showed a significantly higher POP-Q stage compared to women choosing pessary treatment. Our data indicate that women with higher POP-Q stage and non-smokers tended to decide for prolapse surgery. This information could help in clinical practice to guide patients for the best possible treatment decision and strengthen individual counselling.

  • What defines a good website of a Department of Obstetrics and
           Gynecology' A user survey
    • Authors: Günther A. Rezniczek; Ziad Hilal; Alaa Helal; Sven Schiermeier; Clemens B. Tempfer
      Abstract: Purpose The Internet has become a widely used source of healthcare information. Many Departments of Obstetrics and Gynecology use their websites for public relations purposes. It is, however, unclear, what relevant stakeholders such as patients, relatives of patients, physicians, and medical students expect of an Obstetrics and Gynecology Department’s website. Therefore, we evaluated the opinions and expectations of the various stakeholders using a structured questionnaire. Methods We asked gynecologic patients, obstetric patients, relatives of patients, medical students, and physicians to fill in an anonymous questionnaire consisting of general facts about the informant, one open-ended question on expectations and wishes regarding the website, and 28 rating scale questions (7-step visual analog scale ranging from, not important’ to, very important’) covering the topics “website navigation” (4 questions), “first contact” (3 questions), “clinic processes” (7 questions), “facts and figures about the Department” (4 questions), “visual impressions” (5 questions), and “obstetrics-specific items” (5 questions). Questionnaires for physicians included four additional questions about the value of Department websites as an information tool for themselves and their patients. We used descriptive statistics to analyze the data. Results 1458 questionnaires were analyzed (gynecologic patients, n = 615 [42%]; obstetric patients, n = 479 [33%]; relatives of patients, n = 77 [5%]; medical students n = 238 [16%]; physicians, n = 41 [3%]). The number of circulated questionnaires was not recorded and thus, the response rate is unknown. 1304 (89%) respondents used the Internet as a regular source of health care information, 642 (44%) had previously searched an Obstetrics and Gynecology Department website. All respondents rated contact data and information about processes in the clinic highest; whereas, other issues such as medical facts, visual impressions, and website design issues were significantly less important. Pregnant women rated contact information and obstetric facts highest. 90% of physicians regularly used Department websites for patient referrals and rated contact information and medical team details most important. Conclusions When designing a website of an Obstetrics and Gynecology Department, contact information and information about processes in the clinic should be displayed most prominently and be easily accessible. Subsections specifically targeted at obstetric patients and physicians should be provided.

  • Health care and risk of adverse pregnancy outcomes among diabetic women:
           an updated meta-analysis
    • Authors: Guo-Hong Xie; Zan Zheng; Tao-Cheng Liu; Lu-Lu Qing; Xiu-Qin Hong; Wen-Ting Zha; Yuan Lv
      Abstract: Purpose Diabetic women appear to have adverse pregnancy outcomes. Although there were two meta-analyzes that examined the association between health care and adverse pregnancy outcomes, their results were limited because they only included congenital anomaly and perinatal mortality, and they did not clarify the detailed situations of diabetes and health care. This meta-analysis aims to completely evaluate the effects of health care in improving adverse pregnancy outcomes among diabetic mothers. Methods CNKI, EMBASE, Web of Science, and PubMed databases were searched for eligible studies up to December 2017, without any restrictions. Relevant cohort studies characterizing the relationship between health care and adverse pregnancy outcomes were selected for inclusion in the meta-analysis. We also screened the reference list of relevant studies. The fixed-effect models or random-effect models were used to calculate the risk estimates. The potential sources of heterogeneity were explored by stratified and sensitivity analyzes. Results Twenty-one studies with 6685 cases were included in our analysis. Health care was associated with significantly decreased risk of congenital anomaly (RR 0.237; 95% CI 0.166–0.338), perinatal death (RR 0.457; 95% CI 0.294–0.712), large for gestational age (LGA) (RR 0.794; 95% CI 0.640–0.986), and neonatal hypoglycemia (RR 0.672; 95% CI 0.486–0.929). Publication bias was not found in most results, with the exception of congenital anomaly and small for gestational age (SGA). Conclusion Health care is associated with decreased risk of congenital anomaly, perinatal death, LGA, neonatal hypoglycemia.

  • Oviductus Ranae protein hydrolyzate prevents menopausal osteoporosis by
           regulating TGFβ/BMP2 signaling
    • Authors: Xiaohua Li; Xin Sui; Qing Yang; Yinqing Li; Na Li; Xiaozheng Shi; Dong Han; Yiping Li; Xiaowei Huang; Peng Yu; Xiaobo Qu
      Abstract: Purpose It is known that menopausal osteoporosis (MOP) is the most typical form of osteoporosis, which is characterized by low bone mass and microstructure damage of the bone tissue, leading to increased bone fragility and risk of fracture. This study aimed to evaluate the protective effects of Oviductus Ranae protein hydrolyzate (ORPH) on the MOP in vivo. Methods Osteoporosis model was induced by ovariectomy, treated with ORPH 150 or 75 mg kg−1. Body weight and bone mineral density (BMD) of rats were measured at the beginning and the end of the experiment, and femoral maximum load was determined immediately after killing. The expression levels of alkaline phosphatase (ALP), Smad4, tartrate acid phosphatase (TRAP), BMP2, Runx2, CPB, ColI and osteocalcin were examined by RT-PCR or western-blotting. HE staining was used to observe the pathological changes in the femurs. Immunohistochemistry was used to detect the expression of ALP and BMP2. All data were analyzed by SPSS 13.0. Results The results revealed that ORPH had no effect on the weight of normal and osteoporotic rats. ORPH could significantly improve the femur BMD and increase the maximum load of the osteoporotic rats. ORPH could significantly upregulate the expression level of bone formation makers, ALP, osteocalcin, ColI, and Runx2, and downregulate the expression level of bone resorption marker, TRAP. In the ORPH group, the expression levels of BMP2, Smad4, and CPB of key proteins in the TGFβ/BMP2 signaling pathway were significantly upregulated. In addition, immunohistochemistry showed that ALP and BMP2 expression in femurs of the ORPH group was stranger. H&E staining showed that ORPH (150 mg kg−1) significantly increased the thickness of trabeculae and decreased fracture risk. Conclusion Collectively, ORPH plays a role in the prevention and treatment of osteoporosis, which may be a potential anti-osteoporosis drug.

  • Adaptation and qualitative evaluation of encounter decision aids in breast
           cancer care
    • Authors: Pola Hahlweg; Isabell Witzel; Volkmar Müller; Glyn Elwyn; Marie-Anne Durand; Isabelle Scholl
      Abstract: Purpose Shared decision-making is currently not widely implemented in breast cancer care. Encounter decision aids support shared decision-making by helping patients and physicians compare treatment options. So far, little was known about adaptation needs for translated encounter decision aids, and encounter decision aids for breast cancer treatments were not available in Germany. This study aimed to adapt and evaluate the implementation of two encounter decision aids on breast cancer treatments in routine care. Methods We conducted a multi-phase qualitative study: (1) translation of two breast cancer Option Grid™ decision aids; comparison to national clinical standards; cognitive interviews to test patients’ understanding; (2) focus groups to assess acceptability; (3) testing in routine care using participant observation. Data were analysed using qualitative content analysis. Results Physicians and patients reacted positively to the idea of encounter decision aids, and reported being interested in using them; patients were most receptive. Several adaptation cycles were necessary. Uncertainty about feasibility of using encounter decision aids in clinical settings was the main physician-reported barrier. During real-world testing (N = 77 encounters), physicians used encounter decision aids in one-third of potentially relevant encounters. However, they did not use the encounter decision aids to stimulate dialogue, which is contrary to their original scope and purpose. Conclusions The idea of using encounter decision aids was welcomed, but more by patients than by physicians. Adaptation was a complex process and required resources. Clinicians did not follow suggested strategies for using encounter decision aids. Our study indicates that production of encounter decision aids alone will not lead to successful implementation, and has to be accompanied by training of health care providers.

  • Pelvic floor muscle training for prevention and treatment of urinary
           incontinence during pregnancy and after childbirth and its effect on
           urinary system and supportive structures assessed by objective measurement
    • Authors: Ilaria Soave; Simona Scarani; Maddalena Mallozzi; Flavia Nobili; Roberto Marci; Donatella Caserta
      Abstract: Purpose During the second and the third trimesters of pregnancy and in the first 3 months following childbirth, about one-third of women experience urinary incontinence (UI). During pregnancy and after delivery, the strength of the pelvic floor muscles may decrease following hormonal and anatomical changes, facilitating musculoskeletal alterations that could lead to UI. Pelvic floor muscle training (PFMT) consists in the repetition of one or more sets of voluntary contractions of the pelvic muscles. By building muscles volume, PFMT elevates the pelvic floor and the pelvic organs, closes the levator hiatus, reduces pubovisceral length and elevates the resting position of the bladder. Objective of this review is to evaluate the efficacy of PFMT for prevention and treatment of UI during pregnancy and after childbirth and its effect on urinary system and supportive structures assessed by objective measurement techniques. Methods The largest medical information databases (Medline–Pubmed, EMBASE, Lilacs, Cochrane Library and Physiotherapy Evidence Database) were searched using the medical subject heading terms “pelvic floor muscle training”, “prevention”, “urinary incontinence”, “urinary stress incontinence”, “objective measurement techniques”, “pregnancy, “exercise”, “postpartum” and “childbirth” in different combinations. Results and conclusions Overall, the quality of the studies was low. At the present time, there is insufficient evidence to state that PFMT is effective in preventing and treating UI during pregnancy and in the postpartum. However, based on the evidence provided by studies with large sample size, well-defined training protocols, high adherence rates and close follow-up, a PFMT program following general strength-training principles can be recommended both during pregnancy and in the postnatal period.

  • Intermediate trophoblastic tumor: the clinical analysis of 62 cases and
           prognostic factors
    • Authors: Ying Zhang; Shiqian Zhang; Wenqian Huang; Tingting Chen; Hang Yuan; Yumin Zhang
      Abstract: Purpose The aim is to analyze the clinical characteristics of intermediate trophoblastic tumor (ITT). Methods 12 cases diagnosed at Qilu Hospital of Shandong University from January 2005 to December 2016 were investigated. Additionally, 50 cases were selected from MEDLINE and CBM databases between January 2010 and December 2016. The clinical data extracted from those aforementioned 62 cases were analyzed. Results There were 42 cases with placental site trophoblastic tumor (PSTT), 19 cases with epithelioid trophoblastic tumor (ETT), and 1 case with mixed type (PSTT and ETT). No significant differences were found between PSTT and ETT in terms of age, type of antecedent pregnancy, main complaints, serum β-hCG peak, FIGO stage or prognosis. However, the interval between antecedent pregnancy and the onset was longer in ETT than in PSTT (P = 0.01). FIGO stage was irrelevant to serum β-hCG (P = 0.263). All 62 cases underwent surgeries and seven cases preserved fertility. Fifteen cases with high risk factors were not treated with adjuvant chemotherapy. Univariate analysis results showed that age ≧ 40 years, serum β-hCG peak ≧ 1000 IU/L and nonstandard treatment were associated with poor survival, but only age remained significant on multivariate analysis for ITT (P = 0.018). Conclusion PSTT and ETT have similar clinical characteristics generally. Serum β-hCG can not reflect the progress of ITT. Age ≧ 40 years is the independent high risk factor for ITT.

      Abstract: Purpose The two main etiological factors for vulvar squamous cell carcinoma (vSCC) are the vulvar dermatosis lichen sclerosus (LS) and high-risk human papillomavirus (hrHPV). Serpin A1 (α1-antitrypsin) is a serine protease inhibitor, which plays a role in the tumorigenesis of various cancer types. The aim of the study was to evaluate the expressions of Serpin A1 in LS, premalignant vulvar lesions, and vSCC using immunohistochemistry (IHC) and serum analysis, and to compare Serpin A1 stainings to the tumor markers p53 and p16. Methods In total, 120 samples from 74 patients were studied with IHC for Serpin A1, p53 and p16: 18 normal vulvar skin, 53 LS, 9 premalignant vulvar lesions (dVIN/HSIL) and 40 vSCC samples. Serum concentrations of Serpin A1 were analyzed from 30 LS, 44 vSCC and 10 control patients. Expressions were compared to clinical data. Results Tumor cell-specific Serpin A1 overexpression was detected in 88% of vSCC samples, independent of the etiology. The intensity of Serpin A1 expression was significantly higher in vSCC than in healthy vulvar skin, LS, or premalignant vulvar lesions. Serpin A1 showed an association with p53 positivity. No difference in overall survival was found between Serpin A1-, p53-, or p16-positive vSCC patients. Serum concentrations of Serpin A1 were equal in the LS, vSCC, and control groups. Conclusion Tumor cell-specific Serpin A1 overexpression is a potential biomarker in vSCC.

      Abstract: Purpose We address the impact of applying loop electrosurgical excision procedure (LEEP) under direct colposcopic vision teaching to our undergraduates using a self-developed simulation model and a standardized assessment to evaluate the progress of learning. Methods The undergraduate teaching module was composed of a theoretical course on cervical dysplasia, colposcopy, electrosurgery and excisional procedures of the uterine cervix. This was followed by hands-on practical rounds. During the hands-on practice the students performed five “type 1” LEEP under direct colposcopic vision on the self-developed simulator. Based on specimen fragmentation and excision accuracy a score system was established. The students were asked to answer a course evaluation questionnaire. Results The accuracy of the excisions showed a statistically significant improvement during the five training procedures (excision depth 7.34 ± 1.60–8.54 ± 1.67 mm, p = 0.0041; deviation from target cone thickness 0.88 ± 1.16–0.13 ± 0.94 mm, p = 0.0116). The fragmentation of the conus decreased (2.57 ± 1.26–1.29 ± 0.60 pieces, p < 0.0001). All this led to a general improvement of the LEEP score (2.59 ± 1.93–0.84 ± 1.03, p = 0.001). The student’s questionnaire revealed a subjective satisfaction and improvement of their knowledge in pathomechanism, diagnosis and therapy of cervical pathologies. Conclusion Undergraduate surgical training, in cervical excisional procedure, is a successful method in improving the students’ perception and management of cervical pathologies.

      Abstract: Purpose The association between hysterectomy for benign gynecologic disease and ovarian cancer risk was controversial. Thus, we perform a systematic review and meta-analysis to evaluate the effect of hysterectomy and ovarian cancer risk. Methods PubMed, Cochrane Library, and Embase were searched from 2000 toJanuary 2018. A random-effect model was used to obtain the summary odds risks (ORs) and 95% confidence intervals (CIs). Results A total of 18 case–control studies were included in the meta-analysis. We found that there was no statistical significance for ovarian cancer risk following hysterectomy (OR 0.97, 95% CI 0.83–1.12). And in subgroup analysis, the protective effects were observed for invasive endometrioid/clear cell carcinomas after hysterectomy (OR 0.70, 95% CI 0.51, 0.94; I2 = 0%), and no statistical significance for serous and mucinous. Conclusions Hysterectomy showed no relationship with ovarian cancer. But a reduced risk was found for endometrioid-invasive OC. These findings could provide evidence for patients with benign gynecological disease and clinicians to make appropriate decision about whether to conduct hysterectomy.

    • Authors: Katrina Mark; Anja Frost; Heather Hussey; Micael Lopez-Acevedo; Anne E. Burke; Jill Edwardson; Opey Solaru; Patti Gravitt
      Abstract: Purpose To determine rates and factors associated with regression of cervical intraepithelial neoplasia (CIN) 2 + between colposcopic biopsy and therapeutic excisional procedure in standard practice. Methods A retrospective chart review was performed for women undergoing a cervical excisional procedure for CIN 2 + at clinics at three academic institutions over a 3-year period. Cytology, histology, patient age and time-to-excision were analyzed to determine factors influencing rates of regression. Results Of 356 women undergoing excision for CIN 2 + on colposcopic biopsy, 91 (25.3%) of final pathology diagnoses displayed clinically significant regression. Age and time-to-excision were not associated with regression, but referral cytology and severity of initial biopsy histology were, with ASC-H (aOR 0.1, CI 0.03, 0.8) and CIN 3/AIS (aOR 0.4, CI 0.2, 0.7) being less likely to regress than less severe lesions. Conclusions Disease severity by referral cytology or diagnostic biopsy, as opposed to age or length of time-to-excision, is likely the most relevant factor in determination of regression for cervical intraepithelial neoplasia in women undergoing excisional treatment for biopsy-confirmed CIN2 +.

      Abstract: Purpose Alterations in renal dimensions may be an early manifestation of deviation from normality, with possible repercussions beyond intrauterine life. The objective of this study was to establish reference curves for fetal kidney dimensions and volume from 14 to 40 weeks of gestation. Methods This is a prospective longitudinal study of 115 Brazilian participants in the “WHO multicentre study for the development of growth standards from fetal life to childhood: the fetal component”. Pregnant women with clinical and sociodemographic characteristics allowing the full potential fetal growth were followed up from the first trimester until delivery. These women underwent serial sonographic evaluation of fetal kidneys. The longitudinal, anteroposterior and transverse diameters of both fetal kidneys were measured, in addition to calculation of kidney volume. By quantile regression analysis, reference curves of renal measurements related to gestational age were built. Results Standard normal sonographic values of renal biometry were defined during pregnancy. Reference values for the 10th, 50th and 90th centiles of different fetal kidney measurements (longitudinal, anteroposterior, transverse and volume) from the 14th to the 40th week of gestation were fitted. Conclusion The reference curves presented should be of the utmost importance for screening and diagnosis of alterations in renal development during the intrauterine period.

      Abstract: Purpose Decreased oocyte maturation rate (OMR) is associated with worse clinical outcomes in IVF/ICSI cycles. The clinical features inducing decreased OMR remain unknown. The study is designed to explore the factors influencing the incidence of decreased OMR and its effects on clinical outcomes. Methods This is a retrospective case–control study analyzing data from 20,939 ICSI cycles in a reproductive center of university affiliated hospital from January 2015 to December 2017. Patients with a decreased OMR (< 30%) were characterized as Group A and those with an OMR ≥ 30% constituted Group B. Candidate factors of decreased OMR and clinical outcomes were compared between the two groups. Results There were 1.3% cycles with an OMR < 30% and 22.16% of all oocytes retrieved (12.87 per cycle in average) were immature. Primary infertility, longer duration of infertility, larger BMI, more previous assisted reproductive times, less oocytes retrieved were risk factors for decreased OMR. Compared with long agonist protocol, patients received antagonist protocol for COH had a higher incidence of decreased OMR. The fertilization rate and subsequent embryo development of oocytes in Group A were worse than Group B. Implantation rate and clinical pregnancy rate were both lower in Group A than Group B. Conclusion Primary infertility, duration of infertility, BMI, previous assisted reproductive times, number of oocytes retrieved and COH protocol were found to be factors inducing decreased OMR. Patients with decreased OMR had worse clinical outcomes.
