RESUMEN
MV-Flow is a tool enables to acquire spatially and temporally coherent data on low-speed blood flow information. In our case, it allowed a better definition of vein of Galen aneurysmal malformation morphology, venous drainage and feeder vessels than standard ultrasound techniques.
RESUMEN
PURPOSE: Abnormal flow in the ductus venosus (DV) has been reported to be associated with adverse perinatal outcome, chromosomal abnormalities, and congenital heart defects (CHD). Aneuploid fetuses have increased risk of CHD, but there are discrepancies on the performance of this markers in euploid fetuses. The aim of this meta-analysis was to establish the predictive accuracy of DV for CHD. METHODS: MEDLINE, EMBASE, and CINAHL were searched from inception to February 2022. No language or geographical restrictions were applied. Inclusion criteria regarded observational and randomized studies concerning first-trimester DV flow as CHD marker. Random effect meta-analyses to calculate risk ratio (RR) with 95% confidence interval (CI), hierarchical summary receiver-operating characteristics (HSROC), and bivariate models to evaluate diagnostic accuracy were used. Primary outcome was the diagnostic performance of DV in detecting prenatal CHD by means of area under the curve (AUROC). Subgroup analysis for euploid, high-risk, and normal NT fetuses was performed. Quality assessment of included papers was performed using QUADAS-2. RESULTS: Twenty two studies, with a total of 204.829 fetuses undergoing first trimester scan with DV Doppler evaluation, fulfilled the inclusion criteria for this systematic review. Overall, abnormal DV flow at the time of first trimester screening was associated to an increased risk of CHD (RR 6.9, 95% CI 3.7-12.6; I2 = 95.2%) as well in unselected (RR: 6.4, 95% CI 2.5-16.4; I2 = 93.3%) and in euploid (RR: 6.45, 95% CI 3.3-12.6; I2 = 95.8%) fetuses. The overall diagnostic accuracy of abnormal DV in detecting CHD was good in euploid fetuses with an AUROC of 0.81 (95% CI 0.78-0.84), but it was poor in the high-risk group with an AUROC of 0.66 (95% CI 0.62-0.70) and in the unselected population with an AUROC of 0.44 (95% CI 0.40-0.49). CONCLUSIONS: Abnormal DV in the first trimester increases the risk of CHD with a moderate sensitivity for euploid fetuses. In combination with other markers (NT, TV regurgitation) could be helpful to identify fetuses otherwise considered to be at low risk for CHD. In addition to the improvement of the fetal heart examination in the first trimester, this strategy can increase the detection of major CHD at earlier stage of pregnancy.

RESEARCH QUESTION: Several studies have investigated reproductive outcomes following surgical treatment of colorectal endometriosis, mainly segmental colorectal resection. This study examines pregnancy and live birth rates of women with rectosigmoid endometriosis not treated by surgery. DESIGN: A retrospective analysis of data collected between May 2009 and January 2020 related to 215 women affected by rectosigmoid endometriosis wishing to conceive. Patients had a diagnosis of rectosigmoid endometriosis by transvaginal ultrasonography and magnetic resonance imaging enema. Patients with estimated bowel stenosis >70% at computed tomographic colonography and/or subocclusive/occlusive symptoms were excluded. RESULTS: During the median length of follow-up of 31 months (range 13-63 months), the total pregnancy and live birth rates of the study population were 47.9% and 45.1%, respectively. Sixty-two women had a live birth after natural conception (28.8%; 95% confidence interval [CI] 22.8-35.6%) with a median time required to conceive of 10 months (range 2-34 months). Eighty-three women underwent infertility treatments (38.6%, 95% CI 32.1-45.5%); among these, 68 patients underwent IVF either directly (n = 51) or after intrauterine insemination (IUI) failure (n = 17). Time to conception was significantly higher in women having conceived by IVF than in those having conceived naturally (P < 0.001) or by IUI (P = 0.006). In patients undergoing IVF cycles, a worsening of some pain and intestinal symptoms was observed. CONCLUSIONS: At median follow-up of 31 months, women with rectosigmoid endometriosis have a 48% pregnancy rate. However, these patients must be referred to centres specialized in managing endometriosis to properly assess symptoms and degree of bowel stenosis.

INTRODUCTION: Preoperative assessment of deep endometriotic (DE) nodules is necessary to inform patients about the possible treatments and provide informed consent in case of surgery. This study aims to investigate the diagnostic performance of rectal water-contrast transvaginal ultrasonography (RWC-TVS) and sonovaginography (SVG) in women with suspicion of posterior DE. MATERIAL AND METHODS: This prospective comparative study (NCT04296760) enrolled women with clinical suspicion of DE at our institution (Piazza della Vittoria 14 SRL, Genoa, Italy). Exclusion criteria were previous diagnosis of DE by imaging techniques or laparoscopy. All patients underwent RWC-TVS and SVG, independently performed by two gynecological sonologists blinded to the other technique's results. Patients underwent laparoscopic surgery within the following three months; imaging findings were compared with surgical and histological results. RESULTS: In 208 of 281 (74.0%) patients included, posterior DE was surgically confirmed in rectosigmoid (n = 88), vagina (n = 21), rectovaginal septum (n = 34) and uterosacral ligaments (n = 156). RWC-TVS and SVG demonstrated similar sensitivity (SE; 93.8% vs 89.4%; p = 0.210) and specificity (SP; 86.3% vs 79.4%; p = 0.481) in diagnosing posterior DE. Specifically, both examinations had similar accuracy in detecting nodules of uterosacral ligaments (p = 0.779), vagina (p = 0.688) and rectovaginal septum (p = 0.824). RWC-TVS had higher SE (95.2% vs 82.0%; p = 0.003) and similar SP (99.5% vs 98.5%; p = 0.500) in diagnosing rectosigmoid endometriosis and estimated better infiltration of intestinal submucosa (p = 0.039), and distance between these nodules and anal verge (p < 0.001); only RWC-TVS allowed the estimation of bowel lumen stenosis. A similar proportion of discomfort was experienced during both examinations (p = 0.191), although a statistically higher mean visual analog score was reported during RWC-TVS (p < 0.001). CONCLUSIONS: Although RWC-TVS and SVG have similar accuracy in the diagnosis of DE, RWC-TVS performed better in assessment of the characteristics of rectosigmoid endometriosis.

OBJECTIVE: The use of three-dimensional (3D) transvaginal ultrasonography (TVS) has been investigated for the diagnosis of deep endometriosis (DE). This study aimed to evaluate if 3D reconstructions improve the performance of TVS) in assessing the presence and characteristics of bladder endometriosis (BE). DESIGN: This was a single-center comparative diagnostic accuracy study. Participants/Materials, Setting, Methods: Patients referred to our institution (Piazza della Vittoria 14 Srl, Genova, Italy) with clinical suspicion of DE were included. In case of surgery, women underwent systematic preoperative ultrasonographic imaging; an experienced sonographer performed a conventional TVS; another experienced sonographer, blinded to results of the previous exam, performed TVS, with the addition of 3D modality. The presence and characteristics of BE nodules were described in accord with International DE Analysis group consensus. Ultrasound data were compared with surgical and histological results. RESULTS: Overall, BE was intraoperatively found in 34 out of 194 women who underwent surgery for DE (17.5%; 95% confidence interval: 12.8-23.5%). TVS without and with 3D reconstructions were able to detect endometriotic BE in 82.2% (n = 28/34) and 85.3% (n = 29/34) of the cases (p = 0.125). Both the exams similarly estimated the largest diameter of BE (p = 0.652) and the distance between the endometriotic nodule and the closest ureteral meatus (p = 0.341). However, TVS with 3D reconstructions was more precise in estimating the volume of BE (p = 0.031). In one case (2.9%), TVS without and with 3D reconstructions detected the infiltration of the intramural ureter, which was confirmed at surgery and required laparoscopic ureterovesical reimplantation. LIMITATIONS: The extensive experience of the gynecologists performing the ultrasonographic scans, the lack of prestudy power analysis, and the population selected, which may have been influenced by the position of the institution as a referral center specialized in the treatment of severe endometriosis, are limitations of the current study. CONCLUSION: Our results demonstrated the high accuracy of ultrasound for diagnosing BE. The addition of 3D reconstructions does not improve the performance of TVS in diagnosing the presence and characteristics of BE. However, the volume of BE may be more precisely assessed by 3D ultrasound.

RESEARCH QUESTION: The major causes of IVF failure in women with endometriosis have been attributed to decreased ovarian reserve, low embryo quality and impaired receptivity of the endometrium. Dienogest (DNG) has anti-inflammatory and anti-angiogenic activity and so may theoretically improve IVF outcomes in women with endometriosis. This study aimed to evaluate the administration of DNG before IVF in women with endometriosis who had previously failed one IVF cycle. METHODS: This study was based on the retrospective analysis of a prospectively collected database, including 151 women who had failed a previous IVF cycle and all subsequent embryo transfers and had an imaging diagnosis of endometriosis. Patients either directly underwent IVF without receiving hormonal treatment or received 3 months of treatment with DNG (2 mg/daily) before IVF. RESULTS: Eighty-eight (58.3%) patients underwent IVF without previous hormonal treatment, and 63 (41.7%) received pretreatment with DNG. The cumulative implantation, clinical pregnancy and live birth rates were significantly higher in the DNG-treated group (39.7%, 33.3% and 28.6%) than in the non-treated group (23.9%, 18.2% and 14.8%; P = 0.049, 0.037 and 0.043, respectively). The largest diameter of endometriomas significantly decreased after DNG pretreatment (P < 0.001). The use of DNG increased significantly the number of oocytes retrieved (Pâ¯=â¯0.031), two-pronuclear embryos (P = 0.039) and blastocysts (P = 0.005) in women with endometriomas of diameter ≥4 cm. CONCLUSIONS: This study suggest that in patients with endometriosis, IVF outcomes can be improved by pretreatment with DNG. In particular, the use of DNG allows for better oocyte retrieval and blastocysts in patients with large endometriomas.

OBJECTIVES: Rectosigmoid involvement by endometriosis causes intestinal symptoms such as constipation, diarrhea, and dyschezia. A precise diagnosis about the presence, location, and extent of bowel implants is required to plan the most appropriate treatment. The aim of the study was to compare the accuracy of magnetic resonance with distension of the rectosigmoid (MR-e) with computed colonography (CTC) for diagnosing rectosigmoid endometriosis. METHODS: This study was based on the retrospective analysis of a prospectively collected database of patients with suspicion of rectosigmoid endometriosis who underwent both MR-e and CTC, and subsequently were treated by laparoscopy. The findings of imaging techniques were compared with surgical and histological results. RESULTS: Of 90 women included in the study, 44 (48.9%) had rectosigmoid nodules and underwent bowel surgery. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for the diagnosis of rectosigmoid endometriosis were 88.6%, 93.5%, 92.9%, 89.6%, and 91.1% for CTC, and 93.2%, 97.9%, 97.6%, 93.8%, and 95.6% for MR-e. There was no significant difference in the accuracy of both radiologic examinations for diagnosing rectosigmoid endometriosis (P = 0.344). However, MR-e was more accurate than CTC in estimating the largest diameter of the main rectosigmoid nodule (P < 0.001). The pain perceived by the patients was significantly lower during MR-e than during CTC (P < 0.001). CONCLUSIONS: MR-e and CTC have similar diagnostic performance for the diagnosis of rectosigmoid involvement of endometriosis. However, MR-e is more accurate in the estimation of the largest diameter of main rectosigmoid nodule and more tolerated than CTC.

This study aimed to investigate the efficacy of the etonogestrel (ENG)-releasing implant in treating patients with rectovaginal endometriosis. The study was based on the retrospective analysis of a prospectively collected database, including symptomatic women who had ultrasonographic diagnosis of rectovaginal endometriosis. Patients were follow-up at 6, 12 and 24 months from the insertion of the ENG-releasing implant. The intensity of pain symptoms was evaluated using a visual analog scale. The volume of the nodules was estimated by virtual organ computer-aided analysis. The Endometriosis Health Profile (EHP-30) was used to evaluate quality of life. Overall, 43 women were included in the study. The 2-year continuation rate for the ENG-releasing implant was 93.0%. The treatment quickly improved the intensity of non-menstrual pelvic pain, deep dyspareunia, dysmenorrhea, and dyschezia. At 6-month follow-up, there were improvements in all domains of the EHP-30 compared with baseline. Further improvements in the EHP-30 results were observed only in pain sub score at 12-month follow-up and in emotional well-being sub score at 24-month follow-up. At 6-month follow-up the volume of the rectovaginal nodules was significantly lower compared with baseline; a further decrease was observed at 12- and 24-month follow-up. The treatment was well tolerated.

INTRODUCTION: Nowadays, the resection of submucosal myomas is usually performed by hysteroscopy. No previous study has investigated the use of preoperative hormonal therapy before outpatient hysteroscopic myomectomy. OBJECTIVE: To compare the usefulness of 3-month preoperative treatment with ulipristal acetate (UPA) before outpatient hysteroscopic myomectomy in patients with FIGO (International Federation of Gynecology and Obstetrics) type 0-1 myomas. STUDY DESIGN: This prospective patient preference study included women requiring hysteroscopic resection of single FIGO type 0-1 myoma with the largest diameter <2 cm. Patients underwent either preoperative treatment with UPA (5 mg/day) for 3 months or direct surgery. Outpatient myomectomy was performed using the bipolar electrosurgical Versapoint system (Ethicon Gynecare, USA). The primary objective of the study was to compare the rate of complete resections in the 2 study groups. The secondary objective of the study was to compare the operative time and the volume of fluid infused/absorbed. The tertiary objective of the study was to assess the surgical appearance of the myomas in patients treated with UPA. RESULTS: The study included 38 women treated with UPA and 45 women who underwent direct surgery. UPA treatment significantly decreased the volume of uterine myomas (p < 0.001). The percentage of complete resection was higher in patients treated with UPA (89.5%) than in those who underwent direct surgery (68.9%; p = 0.046). Preoperative UPA treatment decreased the operative time (p < 0.001) and the volume of fluid infused (p = 0.016), but it did not significantly affect the volume of fluid absorbed (p = 0.874). The texture of the myoma was not significantly affected by UPA treatment (p = 0.142). CONCLUSIONS: Three-month UPA treatment improves the chance of single-step complete outpatient hysteroscopic resection of single FIGO type 0-1 myoma. Future randomized studies with a larger sample size should confirm these preliminary findings.

OBJECTIVES: The primary objective of the study was to compare the performance of the rectal water transvaginal ultrasonography (RWC-TVS) with and without bowel preparation (BP) in diagnosing rectosigmoid endometriosis. The secondary objectives were to compare the performance of the 2 exams in estimating infiltration of the mucosa, length of the largest rectosigmoid nodules, distance of the nodules from the anal verge, and presence of multifocal disease. METHODS: This prospective study included patients with pain symptoms and intestinal complaints suggestive of endometriosis. Patients underwent RWC-TVS with and without BP within an interval of 1 week to 2 months. Two independent and blinded gynecologists performed the exams. The results of the 2 exams were compared with surgical and histologic findings. RESULTS: A total of 155 patients were included in the study; 92 patients had rectosigmoid endometriosis. There was no significant difference in the performance of RWC-TVS with or without BP in diagnosing rectosigmoid endometriosis (P = .727). There was no significant difference in the performance of RWC-TVS with or without BP in diagnosing infiltration of the mucosa (P = .424) and multifocal disease (P = .688), in estimating the main diameter of the largest nodule (P = .644) and the distance between the more distal rectosigmoid nodule and the anal verge (P = .090). The patients similarly tolerated the 2 exams (P = .799). CONCLUSIONS: Bowel preparation does not improve the performance of RWC-TVS in diagnosing rectosigmoid endometriosis and in assessing the characteristics of these nodules.

BACKGROUND/AIMS: Ulipristal acetate ([UPA], Esmya®) is an orally active selective progesterone-receptor modulator that has been approved as preoperative treatment for uterine myomas. This systematic review aims to summarize the available data on surgical outcomes of patients undergoing myomectomy by hysteroscopy or by laparoscopy after preoperative treatment with UPA. METHODS: this review was performed following PRISMA guidelines and was registered in PROSPERO (CRD42018092201). PubMed, EMBASE, and Medline databases were systematically searched electronically until March 2018 for keywords concerning this topic. There were included only peer-reviewed, English language journal articles. RESULTS: two prospective studies and 4 retrospective studies were included. The effect of UPA on the endometrium does not increase the technical difficulty during hysteroscopic myomectomy, but it increases the chance of complete primary resection in complex hysteroscopic myomectomies. Moreover, UPA does not increase the overall technical difficulty of laparoscopic myomectomy. Contradictory results have been reported on the impact of UPA on the separation of the myoma from the myometrium and on the consistency of the myomas. CONCLUSION: current results support the use of UPA prior to both surgical procedures. Further studies should confirm these preliminary findings and to assess the long-term outcomes of myomectomies following UPA treatment.

Background and objective: Previous studies did not draw a definitive conclusion about the influence of the role of deep endometriosis (DE) and ovarian endometrioma (OE) as risk factor for developing adverse perinatal outcomes in patients affected by endometriosis. This study aimed to investigate if adverse fetal and maternal outcomes, and in particular the incidence of small for gestational age (SGA) infants, are different in pregnant women with OE versus pregnant women with DE without OE. Material and methods: This study was based on a retrospective analysis of a database collected prospectively. The population included in the study was divided into three groups: patients with OE, patients with DE without concomitant OE, and patients without endometriosis (controls). The controls were matched on the basis of age and parity. Demographic data at baseline and pregnancy outcomes were recorded. Results: There was no statistically significant difference in first trimester levels of PAPP-A, first and mid-pregnancy trimester mean Uterine Artery Doppler pulsatile index, estimated fetal weight centile, and SGA fetuses' prevalence for patients with OE, and those with DE without OE in comparison to health women; moreover, there was no statistically significant difference with regard to SGA birth prevalence, prevalence of preeclampsia, and five-minute Apgar score between these three groups. Conclusions: The specific presence of OE or DE in pregnant women does not seem to be associated with an increased risk of delivering an SGA infant. These data seem to suggest that patients with endometriosis should be treated in pregnancy as the general population, thus not needing a closer monitoring.

BACKGROUND: Prenatal diagnosis of coarctation of the aorta (CoA) is still challenging and affected by high rates of false-positive diagnoses. The aim of this study was to ascertain the strength of association and to quantify the diagnostic accuracy of different ultrasound signs in predicting CoA prenatally. METHODS: Medline, Embase, CINAHL, and Cochrane databases were searched. Random-effects and hierarchical summary receiver operating characteristic model meta-analyses were used to analyze the data. RESULTS: Seven hundred ninety-four articles were identified, and 12 (922 fetuses at risk for CoA) articles were included. Mean mitral valve diameter z score was lower (P<0.001) and the mean tricuspid valve diameter z score was higher in fetuses with CoA than in those without CoA (P=0.01). Mean aortic valve diameter z score was lower in fetuses with CoA than in healthy fetuses (P≤0.001), but the ascending aorta diameter, expressed as z score or millimeters, was similar between groups (P=0.07 and 0.47, respectively). Mean aortic isthmus diameter z scores measured either in sagittal (P=0.02) or in 3-vessel trachea view (P<0.001) were lower in fetuses with CoA. Conversely, the mean pulmonary artery diameter z score, the right/left ventricular and pulmonary artery/ascending aorta diameter ratios were higher (P<0.001, P=0.02, and P=0.02, respectively) in fetuses with CoA in comparison with controls, although aortic isthmus/arterial duct diameter ratio was lower in fetuses with CoA than in those without CoA (P<0.001). The presence of coarctation shelf and aortic arch hypoplasia were more common in fetuses with CoA than in controls (odds ratio, 26.0; 95% confidence interval, 4.42-153; P<0.001 and odds ratio, 38.2; 95% confidence interval, 3.01-486; P=0.005), whereas persistent left superior vena cava (P=0.85), ventricular septal defect (P=0.12), and bicuspid aortic valve (P=0.14) did not carry an increased risk for this anomaly. Multiparametric diagnostic models integrating different ultrasound signs for the detection of CoA were associated with an increased detection rate. CONCLUSIONS: The detection rate of CoA may improve when a multiple-criteria prediction model is adopted. Further large multicenter studies sharing the same imaging protocols are needed to develop objective models for risk assessment in these fetuses.

BACKGROUND: Assessment of tricuspid flow has been reported to improve the performance of screening for aneuploidies and congenital heart defects (CHD). However, the performance of tricuspid regurgitation (TR) as a screening marker for CHD in euploid fetuses is yet to be established. The main aim of this meta-analysis was to establish the predictive accuracy of TR for CHD. METHODS: MEDLINE, Embase, and the Cochrane Library were searched electronically utilizing combinations of the relevant medical subject heading for "fetus," "tricuspid regurgitation," and "first trimester." The outcomes explored were prevalence of TR in an euploid population, strength of association between TR and CHD, and predictive accuracy of TR for CHD in euploid fetuses. Summary estimates of sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio for the overall predictive accuracy of TR for the detection of CHD were computed using the hierarchical summary receiver-operating characteristics model. RESULTS: A total of 452 articles were identified; 60 were assessed with respect to their eligibility for inclusion and a total of 4 studies were included in the study. TR was associated with an increased risk of CHD (RR: 9.6, 95% CI 2.8-33.5; I2: 92.7%). The strength of association between TR and CHD persisted when considering fetuses at risk for CHD, such as those with increased nuchal translucency (RR: 7.2, 95% CI 5.2-9.8; I2: 0%), while TR did not show any association with CHD when detected in a population at low risk for cardiac defects (RR: 9.3, 95% CI 0.8-111.8; I2: 93%). The overall diagnostic performance of TR in detecting CHD was poor in detecting CHD (sROC: 0.684, SE: 0.61) with a sensitivity of 35.2% (95% CI 26.9-44.1) and a specificity of 98.6% (95% CI 98.5-98.7). Detection of TR at the 11-14 weeks' scan showed a positive likelihood ratio of 7.2 (95% CI 5.3-9.8) in detecting CHD when applied to a population at risk for CHD such as fetuses with an increased nuchal translucency. CONCLUSION: The detection of TR in the first trimester increases the risk of CHD. However, isolated TR in the first trimester does not seem to be a strong predictor for CHD.

INTRODUCTION: The aim of this study was to evaluate the role of mid-trimester fetal biometry, uterine artery Doppler indices and maternal demographics in prediction of small-for-gestational-age (SGA) birth. MATERIALS AND METHODS: We conducted a retrospective cohort study in a single referral center. The study included 23 894 singleton pregnancies scanned between 19 and 24 weeks of gestation. Maternal demographics included age, body mass index and ethnicity. Fetal biometry, birthweight and uterine artery pulsatility index values were converted into centiles. Multivariable logistic regression analysis was performed and the predictive accuracy was assessed using receiver operating characteristic curve analysis. The main outcome measure was prediction of delivery of preterm and term SGA neonates defined as a birthweight in the lowest centile groups (<10th, <5th and <3rd centiles). RESULTS: Maternal ethnicity, fetal biometry and uterine artery Doppler indices were significantly associated with the risk of SGA <5th centile (p < 0.01). Maternal factors or fetal biometry alone showed poor to moderate performance in prediction of term and preterm SGA <5th centile at a 10% false-positive rate. Uterine artery pulsatility index alone was able to predict 25, 60 and 77% of SGA <5th centile delivering at >37, <37 and <32 weeks of gestation respectively at a 10% false-positive rate; maternal factors, fetal biometry and uterine artery Doppler combined detected 40, 66 and 89% of term, preterm and very preterm SGA <5th centile at a 10% false-positive rate. CONCLUSIONS: Second-trimester screening can identify the majority of pregnancies at high risk of SGA birth and showed a higher performance for earlier gestational ages at birth and lower birthweight centiles.

INTRODUCTION: To evaluate the relative value of mid trimester fetal growth, uterine artery Doppler indices and maternal demographics in prediction of stillbirth. MATERIAL AND METHODS: Retrospective cohort study; 23 894 singleton pregnancies routinely scanned between 19 and 24 weeks' gestation. Maternal characteristics included age, body mass index, ethnicity and medical history. Fetal biometry indices, birthweight and uterine artery pulsatility index values were converted to percentiles and multivariable logistic regression analysis was performed. The predictive accuracy was assessed using receiver operating characteristic curves analysis. The main outcome was prediction of preterm and term stillbirths. RESULTS: Non-Caucasian ethnicity, femur length centile and uterine artery pulsatility index were significantly associated with the risk of stillbirth (all p < 0.01). The detection rate of screening by maternal factors alone was 19% for all stillbirths, and 12 and 14% for term and preterm stillbirth at a 10% false positive rate, respectively. Using femur length centile alone, the detection rates were 27 and 23%, respectively. Uterine artery pulsatility index alone was able to predict 24 and 31% of term and preterm stillbirths. Screening by combining maternal factors, femur length centile and uterine artery Doppler detected 27 and 35% of term and preterm stillbirths at a 10% false positive rate. CONCLUSIONS: Second trimester ultrasound assessment offers an opportunity to identify pregnancies at the highest risk of stillbirth occurring as a consequence of placental dysfunction. This information may be useful to improve pregnancy outcome by identifying women who may benefit from increased ultrasound surveillance and/or timely intervention.

OBJECTIVE: The aims of this study were evaluation of the association of reduced fetal movements (RFM) and small-for-gestational-age (SGA) birth at term and to explore if fetal and maternal outcomes are different with single vs repeated episodes of RFM and normal fetal assessment test results. STUDY DESIGN: This was a retrospective cohort study of all singleton pregnancies referred for RFMs at a tertiary fetal medicine unit from January 2008 through September 2014. Ultrasound and Doppler indices were obtained from a computerized ultrasound database and pregnancy outcome was collected from hospital records. RESULTS: Of the 21,944 women with a singleton pregnancy booked for maternity care during the study period, 1234 women (5.62%) reported RFMs >36+0 weeks. Of these, 1029 women (83.4%) reported a single episode of RFM and 205 (16.6%) had ≥2 presentations for RFM. Women with repeated RFMs had a significantly higher mean uterine artery pulsatility index in the second trimester. The prevalence of SGA baby at birth in women presenting with a single episode as compared to repeated episodes of RFM was 9.8% and 44.2%, respectively (odds ratio, 7.3; 95% confidence interval, 5.1-10.4; P < .05). CONCLUSION: Repeated episodes of RFMs at term are more likely to occur in women with high second-trimester uterine artery Doppler resistance indices and are strongly associated with the birth of SGA infants. Women presenting with repeated episodes of RFM should be treated as being at high risk of placental dysfunction irrespective of the results of prenatal ultrasound and Doppler assessment.

OBJECTIVE: To compare the efficacy of two hormonal therapies in treating symptoms caused by bowel endometriosis. DESIGN: Patient preference study. SETTING: University hospital. POPULATION: A total of 143 women with rectovaginal endometriosis infiltrating the rectum. METHODS: This study was performed between January 2008 and June 2011. Patients were treated with a desogestrel-only contraceptive pill or with the sequential combined contraceptive vaginal ring for 12 months. MAIN OUTCOME MEASURES: The primary endpoint of the study was the rate of satisfied patients at 12-month follow up. The changes in symptoms and in the volume of the nodules were secondary endpoints. RESULTS: At 12-month follow up, the rate of satisfied patients was higher in the group treated with the desogestrel-only contraceptive pill than in the group treated with the sequential combined contraceptive vaginal ring (p = 0.004). When only changes in gastrointestinal symptoms were considered, 50% of patients treated with the desogestrel-only contraceptive pill and 31.3% of those treated with the sequential combined contraceptive vaginal ring were satisfied (p = 0.037). The reduction in the volume of the nodules, the percentages of patients who discontinued the therapy after the completion of the study and of those who decided to undergo surgery were similar between the two groups. CONCLUSIONS: Both hormonal therapies are efficacious in treating symptoms caused by rectovaginal endometriosis infiltrating the rectum. Patient satisfaction is higher with the desogestrel-only pill than with a vaginal ring.

PURPOSE: To evaluate the changes in the volume of rectovaginal endometriotic nodules infiltrating the rectum during 12-month treatment with hormonal therapies. MATERIALS AND METHODS: This prospective, non-randomized, self-controlled clinical trial included patients with rectovaginal endometriotic nodules infiltrating at least the muscularis propria of the rectum, who received one of the following therapies: norethisterone acetate, triptorelin and tibolone, norethisterone acetate and letrozole, desogestrel, sequential oral contraceptive pill. The volume of the nodules was determined by virtual organ computer-aided analysis (VOCAL, GE Healthcare, USA) at baseline and after 6 and 12 months of treatment. RESULTS: Eighty-three women (90.2 %) completed the 12-month treatment. When compared with baseline values, the volume of the nodules decreased at 6-month (p < 0.001) and 12-month treatment (p < 0.001). After 12-month treatment, the volume of the nodules decreased in all study groups. The volume of the nodules decreased during therapy in 68 women (73.9 %) and increased in 11 women (12.0 %). CONCLUSION: 12-month administration of hormonal therapies reduces the volume of rectovaginal endometriotic nodules infiltrating the rectum in the majority of cases.
