Abstract
OBJECTIVE To assess the diagnostic performance of transvaginal ultrasound (TVUS) for preoperative evaluation of lymph node metastasis in gynecological cancers. METHODS A systematic review and meta-analysis was performed. All studies published between January 1990 to May 2023 evaluating the role of ultrasound for detecting lymph node metastasis (index test) in gynecological cancers, using histopathological analysis, as reference standard were included. Quality was assessed using QUADAS-2. Pooled sensitivity, specificity and diagnostic odds ratio of TVUS were estimated. RESULTS The search identified 2638 citations. Eight studies comprising 967 women were included. The mean prevalence of pelvic lymph nodes metastasis was 24.2%, [14%-65.6%]. The risk of bias was low for most domains assessed. Overall pooled sensitivity, specificity and diagnostic odds ratio of TVUS were 41% (95% confidence interval [CI] =26%-58%), 98% (95%CI=93%-99%) and 32 (95%CI=14-72), respectively. Heterogeneity in TVUS evaluation was high between studies, both for sensitivity and specificity. No publication bias was found (p=0.46). CONCLUSION TVUS showed a high-pooled specificity for the detection of pelvic lymph node metastasis in gynecological cancers. However, pooled sensitivity was low.

Abstract
The purpose of this State-of-the-Art Review was to provide a strategic analysis, in terms of strengths, weaknesses, opportunities and threats (SWOT analysis), of the current evidence regarding the management of uterine isthmocele (Cesarean scar defect). Strengths include the fact that isthmocele can be diagnosed on two-dimensional transvaginal ultrasound, and that surgical repair may restore natural fertility potential and prevent secondary infertility, as well as reduce the risk of miscarriage and other obstetric complications. However, there is a lack of high-quality evidence regarding the best diagnostic method and criteria, as well as the potential benefits of surgical repair with respect to fertility. There is a need for experienced surgeons skilled in the various isthmocele repair techniques. Isthmocele repair does not prevent the need for Cesarean delivery in subsequent pregnancies. There is increasing awareness regarding the accuracy of transvaginal ultrasound in diagnosing isthmocele. This may lead to surgical correction and prevention of obstetric and perinatal complications in subsequent pregnancies, including Cesarean scar pregnancy. Regarding threats, the existence of different surgical techniques means that there is a risk of selecting an inadequate approach if the type of isthmocele and the patient's characteristics are not considered. There is a risk of overtreatment when asymptomatic defects are repaired surgically. Finally, there is an absence of cost-effectiveness analyses to justify routine repair. Thus, while there are many data suggesting that isthmocele has an adverse effect on both natural fertility and the outcome of assisted reproduction techniques, high-quality evidence to support surgical isthmocele repair in all asymptomatic patients desiring future fertility are lacking. There is increasing agreement to recommend hysteroscopic repair of isthmocele as a first-line approach as long as the residual myometrial thickness is at least 2.5-3.0 mm. © 2023 The Authors.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy of different ultrasound signs for diagnosing adnexal torsion, using surgery as the reference standard. METHODS This was a systematic review and meta-analysis of studies published between January 1990 and November 2021 evaluating ovarian edema, adnexal mass, ovarian Doppler flow findings, the whirlpool sign and pelvic fluid as ultrasound signs (index tests) for detecting adnexal torsion, using surgical findings as the reference standard. The search for studies was performed in PubMed/MEDLINE, CINAHL, Scopus, The Cochrane Library, ClinicalTrials.gov and Web of Science databases. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool was used to evaluate the quality of the studies. Pooled sensitivity, specificity, and positive and negative likelihood ratios were calculated separately, and the post-test probability of adnexal torsion following a positive or negative test was also determined. RESULTS The search identified 1267 citations after excluding duplicates. Eighteen studies were ultimately included in the qualitative and quantitative syntheses. Eight studies (809 patients) analyzed the presence of ovarian edema, eight studies (1044 patients) analyzed the presence of an adnexal mass, 14 studies (1742 patients) analyzed ovarian Doppler flow, six studies (545 patients) analyzed the whirlpool sign and seven studies (981 patients) analyzed the presence of pelvic fluid as ultrasound signs of adnexal torsion. Overall, the quality of most studies was considered to be moderate or good. However, there was a high risk of bias in the patient-selection and index-text domains (with the exception of the whirlpool sign) in a significant proportion of studies. Pooled sensitivity, specificity, and positive and negative likelihood ratios of each ultrasound sign were 58%, 86%, 4.0 and 0.49 for ovarian edema, 69%, 46%, 1.3 and 0.67 for adnexal mass, 65%, 91%, 7.6 and 0.38 for the whirlpool sign, 53%, 95%, 11.0 and 0.49 for ovarian Doppler findings and 55%, 69%, 1.7 and 0.66 for pelvic fluid. Heterogeneity was high for all analyses. CONCLUSIONS The presence of an adnexal mass or pelvic fluid have poor diagnostic accuracy as ultrasound signs of adnexal torsion, while the presence of ovarian edema, the whirlpool sign and decreased or absent ovarian Doppler flow have good specificity but moderate sensitivity for detecting adnexal torsion. © 2022 The Authors.

Abstract
OBJECTIVE The aim of this systematic review and meta-analysis was to evaluate the diagnostic accuracy of the sliding sign on transvaginal ultrasound (TVS) in detecting pouch of Douglas obliteration and bowel involvement in patients with suspected endometriosis, using laparoscopy as the reference standard. METHODS A search for studies evaluating the role of the sliding sign in the assessment of pouch of Douglas obliteration and/or bowel involvement using laparoscopy as the reference standard published from January 2000 to October 2021 was performed in PubMed/MEDLINE, Web of Science, CINAHL, The Cochrane Library, ClinicalTrials.gov and SCOPUS databases. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was used to evaluate the quality of the studies. Analyses were performed using MIDAS and METANDI commands in STATA. RESULTS A total of 334 citations were identified. Eight studies were included in the analysis, resulting in 938 and 963 patients available for analysis of the diagnostic accuracy of the sliding sign for pouch of Douglas obliteration and bowel involvement, respectively. The mean prevalence of pouch of Douglas obliteration was 37% and the mean prevalence of bowel involvement was 23%. The pooled estimated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the sliding sign on TVS for detecting pouch of Douglas obliteration were 88% (95% CI, 81-93%), 94% (95% CI, 91-96%), 15.3 (95% CI, 10.2-22.9), 0.12 (95% CI, 0.07-0.21) and 123 (95% CI, 62-244), respectively. The heterogeneity was moderate for sensitivity and low for specificity for detecting pouch of Douglas obliteration. The pooled estimated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the sliding sign on TVS for detecting bowel involvement were 81% (95% CI, 64-91%), 95% (95% CI, 91-97%), 16.0 (95% CI, 9.0-28.6), 0.20 (95% CI, 0.10-0.40) and 81 (95% CI, 34-191), respectively. The heterogeneity for the meta-analysis of diagnostic accuracy for bowel involvement was high. CONCLUSION The sliding sign on TVS has good diagnostic performance for predicting pouch of Douglas obliteration and bowel involvement in women with suspected endometriosis. © 2022 The Authors.

Abstract
OBJECTIVE To evaluate the accuracy of transvaginal sonography (TVS) for detecting parametrial deep endometriosis, using laparoscopy as the reference standard. METHODS A search was performed in PubMed/MEDLINE and Web of Science for studies evaluating TVS for detecting parametrial involvement in women with suspected deep endometriosis, as compared with laparoscopy, from January 2000 to December 2020. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool was used to evaluate the quality of the studies. Pooled sensitivity, specificity and positive and negative likelihood ratios for TVS in the detection of parametrial deep endometriosis were calculated, and the post-test probability of parametrial deep endometriosis following a positive or negative test was determined. RESULTS The search identified 134 citations. Four studies, comprising 560 patients, were included in the analysis. The mean prevalence of parametrial deep endometriosis at surgery was 18%. Overall, the pooled estimated sensitivity, specificity and positive and negative likelihood ratios of TVS in the detection of parametrial deep endometriosis were 31% (95% CI, 10-64%), 98% (95% CI, 95-99%), 18.5 (95% CI, 8.8-38.9) and 0.70 (95% CI, 0.46-1.06), respectively. The diagnostic odds ratio was 26 (95% CI, 10-68). Heterogeneity was high. Visualization of a lesion suspected to be parametrial deep endometriosis on TVS increased significantly the post-test probability of parametrial deep endometriosis. CONCLUSION TVS has high specificity but low sensitivity for the detection of parametrial deep endometriosis. © 2021 The Authors.

Abstract
BACKGROUND To investigate the value of a single determination of hyperglycosylated hCG (hCG-H) for predicting the clinical outcome of patients with threatened abortion in the first trimester of pregnancy. METHODS Prospective study performed on 86 consecutively selected women with a diagnosis of threatened abortion and viable intrauterine pregnancy in the first trimester of pregnancy, conducted in two tertiary care hospitals. All patients underwent a single blood sample to determine hCG-H and total hCG serum levels and a transvaginal ultrasound 12-24 hours after diagnosis. Patients were monitored to determine whether the outcome was a miscarriage before the 20th week of pregnancy. RESULTS Forty-three women (50%) had a miscarriage during the follow-up. We observed a very high correlation between hCG-H and total hCG (r?=?0.91, p?<?0.001). Median hCG-H and total hCG from pregnancies with normal outcome was signif-icantly higher than those ending in abortion. hCG-H and total hCG were very similar predictors of pregnancy outcomes (AUC: 0.90 and 0.89, respectively). The ratio hCG-H / total hCG was a poor predictor (AUC: 0.64). CONCLUSION A single hCG-H assay is helpful for predicting pregnancy outcomes in women with first trimester threatened abortion and viable or potentially viable pregnancy at the time of presentation. However, hCG-H is not a better predictor than total hCG.

Abstract
OBJECTIVE To determine the feasibility,tolerability, and safety of the ultrasound assessment of tubal patency using foam as contrast. METHODS This was a prospective multicenter study of 915 infertile nulliparous women scheduled for sonohysterosalpingography with foam instillation (HYFOSY) for tubal patency testing as a part of the fertility workup. Clinical and sonographic data were recorded into a web-shared database. Tubal patency, cervical catheterization, pain during the procedure and post-procedural complications were collected. Patients reported discomfort or pain experienced during the procedure with a visual analogue scale (VAS) score. RESULTS Nine hundred fifteen women were included in the final analysis. Median age was 34 (range, 21-45) years and median body mass index was 23 (range, 16-41) kg/m2. Of 839 women, only 8(0.95 %) cases were abandoned due to impossibility of introducing the intracervical catheter. Most of the cervical os were easily cannulated with either paediatric nasogastric probes or special catheter for intrauterine insemination / sonohysterosalpingography 688/914(75.3 %). With a median instillation of 4 mL (range 1-16) of foam, both tubes were identified in 649/875 (70.9 %) patients, while unilateral patency was observed in 190/875 (20.8 %). Only 36/875 (3.9 %) of the women had bilateral tubal obstruction. The median VAS score for perception of pain during HyFoSy examination was 2 (range 0-10), and only 17 (1.9 %) of women reported severe pain (VAS ≥ 7). Pain was unrelated to tubal patency or tubal blockage. Unexpectedly, difficult cervical catheterizations that needed tenaculum, were more likely associated with mild pain during procedure [nasogastric probe group 176/289 (70.9 %) vs. insemination catheter group 166/399 (41.6 %) vs. tenaculum group 190/218(87.2 %) p < 0.001]. Finally, among 915 patients, we only noticed 3 (0.32 %) complications of the technique: two vasovagal episodes and a mild urinary infection. CONCLUSION HYFOSY is a feasible, well-tolerated and safe technique for the evaluation of tubal patency in infertile women.

Abstract
OBJECTIVE To compare the diagnostic performance of two-dimensional transvaginal sonography (TVS) and saline contrast sonohysterography (SCSH) for the diagnosis of endometrial polyps in studies that used both tests in the same group of patients. METHODS This was a systematic review and meta-analysis. An extensive search was conducted of Medline (PubMed), Cochrane Library and Web of Science, for studies comparing the diagnostic performance of TVS and SCSH for identifying endometrial polyps, published between January 1990 and December 2019, that reported a definition of endometrial polyp on TVS and SCSH and used pathologic analysis as the reference standard. Quality of the included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. A random-effects model was used to determine pooled sensitivity, specificity and positive and negative likelihood ratios of TVS and SCSH in the detection of endometrial polyps. Subanalysis according to menopausal status was performed. RESULTS In total, 1278 citations were identified; after exclusions, 25 studies were included in the meta-analysis. In the included studies, the risk of bias evaluated using QUADAS-2 was low for most of the four domains, except for flow and timing, which had an unclear risk of bias in 13 studies. Pooled sensitivity, specificity and positive and negative likelihood ratios for TVS in the detection of endometrial polyps were 55.0% (95% CI, 46.0-64.0%), 91.0% (95% CI, 86.0-94.0%), 5.8 (95% CI, 3.9-8.7) and 0.5 (95% CI, 0.41-0.61), respectively. The corresponding values for SCSH were 92.0% (95% CI, 87.0-95.0%), 93.0% (95% CI, 91.0-95.0%), 13.9 (95% CI, 9.9-19.5) and 0.08 (95% CI, 0.05-0.14), respectively. Significant differences were found when comparing the methods in terms of sensitivity (P < 0.001), but not for specificity (P = 0.0918). Heterogeneity was high for TVS and moderate for SCSH. On subanalysis according to menopausal status, SCSH was found to have higher diagnostic accuracy in both pre- and postmenopausal women; sensitivity and specificity did not differ significantly between the groups for either TVS or SCSH. CONCLUSION Given that SCSH has better diagnostic positive and negative likelihood ratios than does TVS in both pre- and postmenopausal women, those with clinical suspicion of endometrial polyps should undergo SCSH if TVS findings are inconclusive. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVES To perform an external validation of the diagnostic performance of the three-step strategy proposed by the International Ovarian Tumor Analysis (IOTA) group for classifying adnexal masses as benign or malignant, when ultrasound is performed by non-expert sonographers in the first two steps. The second objective was to assess the diagnostic performance of an alternative strategy using simple-rules risk (SRR), instead of simple rules (SR), in the second step. METHODS This was a prospective observational study conducted at two university hospitals, from September 2015 to August 2017, of consecutive patients diagnosed with an adnexal mass. All women were evaluated by ultrasound using the IOTA three-step strategy. Non-expert sonographers performed the first step (use of simple descriptors to classify the masses) and the second step (use of SR if the mass could not be classified in the first step); masses that could not be classified in the first two steps were categorized by an expert sonographer based on their subjective assessment (third step). The reference standard was histological diagnosis in patients who underwent surgery or at least 12 months of follow-up in cases managed expectantly. The sensitivity, specificity, positive (LR+) and negative (LR-) likelihood ratios and overall accuracy of the IOTA three-step strategy were estimated. Furthermore, we evaluated retrospectively an alternative two-step strategy using SRR in the second step to categorize the masses not classifiable with simple descriptors, classifying the lesions as being of low, intermediate or high risk for malignancy. The diagnostic performance of this strategy was estimated by calculating its sensitivity and specificity, assuming surgical intervention for intermediate- or high-risk lesions. RESULTS The study included 283 patients (median age, 48 (range, 18-90) years), of whom 165 (58.3%) were premenopausal and 118 (41.7%) postmenopausal. Two hundred and sixteen (76.3%) women underwent surgery (154 benign and 62 malignant masses) and 67 (23.7%) were managed expectantly with serial ultrasound follow-up for at least 12 months. All expectantly managed masses were considered benign because no sonographic changes suggestive of malignancy were observed during follow-up. Simple descriptors could be applied in 126 (44.5%) masses. Of the remaining 157 lesions, 112 (39.6%) could be characterized using SR. Therefore, 238 (84.1%) masses could be classified by non-expert sonographers in the first two steps. Of the remaining 45 (15.9%) masses, all could be classified by an expert sonographer. Overall sensitivity, specificity, LR+ and LR- of the IOTA three-step strategy were 95.2%, 97.7%, 42.1 and 0.05, respectively. The diagnostic accuracy was 97.2%. Following the two-step strategy using SRR in the second step, of the 157 lesions not classified with simple descriptors, 42, 38 and 77 presented low, intermediate or high risk for malignancy, respectively. Based on this method, 210 women would have undergone surgical treatment. The sensitivity and specificity of this two-step strategy were 98.4% and 63.8%, respectively. CONCLUSIONS The IOTA three-step strategy shows high accuracy for discriminating between benign and malignant adnexal lesions when used by non-expert sonographers. An alternative strategy using the SRR calculator in the second step might improve on this diagnostic performance by decreasing the number of surgical interventions and increasing sensitivity.

Abstract
OBJECTIVE To compare clinical and sonographic features of benign, borderline, and malignant invasive mucinous ovarian tumors (MOTs). MATERIALS AND METHODS Retrospective observational multicenter study comprising 365 women (mean age: 46.1 years) with a histologically confirmed benign, borderline or malignant invasive MOT. Clinical data (patient's age, patient's complaints), tumor markers (CA-125 and CA-1 9.9), and sonographic data (tumor size, bilaterality, morphology -unilocular, multilocular, unilocular-solid, multilocular-solid and solid-, and IOTA color score) were reviewed and compared among these three groups. Women with ultrasound evidence on intra-abdominal disease spread were excluded. RESULTS Three hundred seventy-eight MOTs (14 women had bilateral lesions) were analyzed. Histologically, 287 tumors were benign, 51 were borderline, and 40 were malignant. No difference in patient's mean age was observed. Women with borderline or invasive tumors were less frequently asymptomatic. Tumors were larger in case of invasive lesions. Borderline and invasive tumors showed solid components and exhibited IOTA color score 3 or 4, more frequently than benign lesions (p < 0.001). However, the authors discovered that 16 out of 51 (31.4%) of borderline tumors and six out of 40 (15.0%) of invasive cancers had no solid components and a color score 1 or 2, and were considered as a benign lesion by the sonolo- gist. On the other hand, 96 out of 287 (33.4%) benign mucinous cystadenoma exhibited solid components and/or a color score of 3 or 4. CONCLUSIONS In spite of statistical differences, the authors observed significant overlapping in ultrasound features among benign, borderline, and invasive ovarian mucinous tumors that renders a difficult accurate preoperative discrimination among these lesions.

Abstract
OBJECTIVE To assess the diagnostic performance of a three-step strategy proposed by the International Ovarian Tumor Analysis (IOTA) Group for discriminating between benign and malignant adnexal masses. METHODS This was a prospective observational study, performed at two tertiary-care university hospitals, of women diagnosed with an adnexal mass on transvaginal or transabdominal ultrasound between December 2012 and December 2014. Women were scheduled for an ultrasound evaluation, which was initially performed by non-expert examiners. The examiner had to classify the mass using 'simple descriptors' (first step) and, if not possible, using 'simple rules' (second step). For inconclusive masses, an expert examiner classified the mass according to their subjective impression (third step). Masses were managed expectantly, with serial follow-up examinations, or surgically, according to ultrasound findings and clinical symptoms. Histology was used as the reference standard. Masses that were managed expectantly with at least 1 year of follow-up were considered as benign for analytical purposes. Women with less than 1 year of follow-up were not included in the study. RESULTS Six hundred and sixty-six women were included (median age, 41 (range, 18-81) years) of whom 514 were premenopausal and 152 were postmenopausal. Based on the three-step strategy, 362 women had surgical removal of the mass (53 malignant and 309 benign), 71 masses resolved spontaneously and 233 persisted. Four hundred and forty-eight (67.3%) of 666 masses could be classified using simple descriptors and, of the 218 that could not, 147 (67.4%) were classified using simple rules. Of the remaining 71 masses, the expert examiner classified 45 as benign, 12 as malignant and 14 as uncertain. Overall sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of the three-step strategy were 94.3%, 94.9%, 18.6 and 0.06, respectively. CONCLUSION The IOTA three-step strategy, based on the sequential use of simple descriptors, simple rules and expert evaluation, performs well for classifying adnexal masses as benign or malignant.

Abstract
OBJECTIVE To compare diagnostic performance of preoperative transvaginal ultrasound (TVS) and intraoperative macroscopic examination for determining myometrial infiltration in women with low-risk endometrial cancer, and to estimate the agreement between the two methods. METHODS This was a single-center observational study comprising women with preoperative diagnosis of well- or moderately differentiated endometrioid carcinoma of the endometrium. All women underwent preoperative TVS by a single examiner. According to the examiner's subjective impression, myometrial infiltration was stated as ≥ 50% or < 50%. Surgical staging was performed in all cases. Intraoperative macroscopic examination of the removed uterus was performed by pathologists who were unaware of the ultrasound findings, and myometrial infiltration was stated as ≥ 50% or < 50%. Definitive histological diagnosis of myometrial infiltration was made by frozen section analysis and was used as the gold standard. Sensitivity and specificity with 95% CIs were calculated for TVS and intraoperative macroscopic inspection and compared using McNemar's test. Agreement between TVS and intraoperative macroscopic inspection was estimated using Cohen's kappa index (κ) and percentage of agreement. RESULTS Of 209 eligible women, 152 were ultimately included. Mean (± SD) age was 60.9 ± 10.2 years, with a range of 32-91 years. Definitive histological diagnosis revealed that myometrial infiltration was < 50% in 114 women and ≥ 50% in 38 women. Sensitivity and specificity of TVS for detecting deep myometrial infiltration were 81.6% and 89.5%, respectively, whereas the respective values for intraoperative macroscopic examination were 78.9% and 90.4% (McNemar's test, P > 0.05 when comparing TVS and intraoperative macroscopic examination). Agreement between methods was moderate with κ = 0.54 (95% CI, 0.39-0.69) and percentage of agreement of 82%. CONCLUSIONS Although the agreement between preoperative TVS and intraoperative macroscopic examination for detecting deep myometrial infiltration was only moderate, both methods had similar accuracy when compared with frozen section histology. Preoperative TVS might reasonably be proposed as a method for assessing myometrial infiltration as an alternative to intraoperative macroscopic examination, especially when performed by an experienced examiner and image quality is not poor.

Abstract
OBJECTIVE To evaluate the role of transvaginal/transrectal ultrasound for preoperative identification of high-risk cases among women with well-differentiated (G1) or moderately differentiated (G2) endometrioid carcinoma of the endometrium. METHODS This was a single-center prospective observational cohort study comprising a consecutive series of women with a preoperative diagnosis of G1/G2 endometrioid carcinoma of the endometrium. All women underwent transvaginal or transrectal ultrasound examination by a single examiner. According to the examiner's subjective impression, patients were considered high risk if myometrial infiltration was ≥ 50% and/or involvement of the cervix and/or adnexa was suspected. FIGO surgical staging was performed in all cases. According to definitive histological data regarding myometrial infiltration, cervical involvement and adnexal involvement, women were classified as low risk (no myometrial infiltration, no cervical involvement and no adnexal involvement) or high risk (myometrial infiltration ≥ 50% and/or cervical involvement and/or adnexal involvement). Sensitivity, specificity and positive (LR+) and negative (LR-) likelihood ratios, with 95% CIs, of transvaginal/transrectal ultrasound for detecting stage ≥ IB were calculated. Agreement between risk determined by transvaginal/transrectal ultrasound and postoperative definitive histology was calculated. RESULTS Of 209 eligible women, 169 were included in the study. Mean (± SD) age of the study cohort was 60.7 ± 10.3 years, with a range of 32-91 years. Sensitivity, specificity, LR+ and LR- of transvaginal/transrectal ultrasound identifying high-risk cases according to myometrial infiltration, cervical involvement and adnexal involvement were 78.0% (95% CI, 63.7-88.0%), 89.1% (95% CI, 81.7-93.8%), 7.14 (95% CI, 4.19-12.18) and 0.25 (95% CI, 0.15-0.42), respectively. CONCLUSIONS Preoperative transvaginal/transrectal ultrasound may play a significant role in identifying high-risk cases among those with G1/G2 endometrioid carcinoma of the endometrium according to preoperative biopsy, and could be a useful test in this clinical setting.

Abstract
BACKGROUND The external validation of predictive model of late preeclampsia in a low volume and low risk obstetrical setting. METHODS A cohort was created of 174 singleton pregnancies of 11+0-13+6 gestational weeks at Clinica Universidad Navarra from September 2011 to March 2013, which was considered as a validation cohort of a previously described model for late PE (Hospital Clinic, Barcelona). RESULTS A total of 7 (4%) women developed late PE. In the validation cohort the area under the curve of the model was 0.69 (95% CI 0.45-0.93). Detection rates for a 5, 10 and 15% of false positive rates were 21.9, 31.4% and 38.6% respec-tively. When comparing the areas under the curve of the validation cohort with the construction cohort, no statistical differences were found (p=0.68). CONCLUSION The combination of maternal history, pregnancy associated plasma protein-A and mean arterial pressure is moderately useful to predict preeclampsia in a low risk and low volume obstetrical setting. The predictive model of the Clinic Hospital of Barcelona is a valid tool in predicting late preeclampsia in this setting.

Abstract
OBJECTIVE To review the diagnostic accuracy of transvaginal ultrasound (TVS) in the preoperative detection of deep myometrial infiltration in patients with endometrial cancer, comparing subjective and objective methods. METHODS An extensive search was performed in MEDLINE (PubMed) and EMBASE for studies published between January 1989 and December 2014. The eligibility criterion was use of TVS for preoperative assessment of myometrial infiltration by subjective evaluation and/or objective measurements. Objective measurements included, specifically, the approaches of Gordon (ratio of the distance between endometrium-myometrium interface and maximum tumor depth to the total myometrial thickness) and Karlsson (endometrial tumor thickness/anteroposterior uterine diameter ratio), in women with endometrial cancer, using the surgical pathological data as a reference standard. Study quality was assessed using the QUADAS-2 tool. RESULTS Our extended search identified a total of 184 citations, among which we examined the full text of 24 articles. Overall pooled sensitivity, specificity, positive likelihood ratio (LR+) and negative likelihood ratio (LR-) of TVS for detecting deep myometrial infiltration were 82% (95% CI, 76-87%), 81% (95% CI, 76-85%), 4.3 (95% CI, 3.6-5.3) and 0.22 (95% CI, 0.16-0.30), respectively. We did not observe differences among the three methods in terms of diagnostic performance. Significant heterogeneity was found for sensitivity and specificity of all three methods (I(2) range, 60.6-95.0). The main limitation was that very few studies compared different approaches in the same set of patients. CONCLUSION Diagnostic performance of TVS for detecting deep myometrial infiltration in women with endometrial cancer is moderate.

Abstract
OBJECTIVE To evaluate the contribution of three-dimensional (3D) power Doppler angiography (3D-PDA) to the differential diagnosis of adnexal masses. METHODS This was a prospective study in women diagnosed with a persistent adnexal mass and subsequently scheduled for surgery in a tertiary university hospital. All women were evaluated by transvaginal/transrectal ultrasound according to a predetermined three-step protocol, with transabdominal ultrasound being performed in some cases. First, morphological evaluation of the mass was performed using gray-scale 'pattern recognition' (first step). Lesions diagnosed as having a benign pattern were considered as being at low risk of malignancy whereas tumors with solid components, ascites and/or signs of carcinomatosis were considered as being at high risk of malignancy. In both cases no further test was performed and a decision regarding clinical management, either for follow-up or surgery, was taken. Tumors with solid components but without signs of ascites or carcinomatosis were considered as being at intermediate risk of malignancy. These lesions were assessed by two-dimensional (2D) PDA to evaluate tumor vascularity (color score) (second step). Solid tumors with a color score of 1 or 2 were considered as benign and no further test was performed, while tumors with a color score of 2, 3 or 4 within solid components or a color score of 3 or 4 in the case of a solid tumor were considered as malignant. The latter group underwent 3D-PDA assessment (third step). Vascularization index (VI) was calculated in a 1-mL sphere of the most vascularized area of the tumor. When a VI ≥ 24.015% was found, the tumor was considered as malignant. All masses were removed surgically and definitive histological diagnosis was used as the gold standard. Sensitivity and specificity for each strategy were calculated and compared. In the case of bilateral tumors, only the more suspicious one was used for analysis. RESULTS A total of 367 adnexal masses diagnosed in 367 women (mean age, 46.5 (range, 18-80) years) were evaluated during the study period. Of these, 86 masses were malignant and 281 were benign. The sensitivity and specificity for each assessment strategy were as follows: one-step, 97.7% and 78.6%; two-step, 94.2% and 97.9% (P < 0.001 for specificity when compared with that of one-step); three-step, 90.7% and 98.9% (not statistically significant when compared with that of two-step). CONCLUSIONS The addition of 2D-PDA in the differential diagnosis of an adnexal mass significantly increases specificity while sensitivity remains high; however performing subsequent 3D-PDA does not provide additional information or further improve diagnostic performance subsequent to 2D-PDA.

Abstract
OBJECTIVE To estimate the interobserver agreement between a trainer and trainees in assigning the International Ovarian Tumor Analysis (IOTA) color score to adnexal masses using three-dimensional (3D) volumes and videoclips. METHODS Fifty-one digital videoclips and 3D volumes of a non-consecutive series of adnexal masses were used for this study. One trainer and four trainees evaluated first the 3D volume and 1 week later a videoclip from the same mass. They had to assign IOTA color scores according to their impression of the amount of color content in each case. Interobserver agreement between trainer and trainees was assessed using Cohen's weighted kappa index with 95% CIs and percentage of agreement. RESULTS When using 3D volumes, interobserver agreement was good for three out of four pairs of comparisons and very good for one (kappa values of 0.70, 0.68, 0.81 and 0.71 for trainees A, B, C and D, respectively). When using videoclips, interobserver agreement was very good for two out of four pairs of comparisons and good for two (kappa values of 0.84, 0.80, 0.68 and 0.86 for Trainees A, B, C and D, respectively). CONCLUSION Evaluation of IOTA color scores in adnexal masses using either videoclips or 3D volumes is reproducible even in the hands of trainees after a short training program.

Abstract
INTRODUCTION The aim of this research is to contribute to knowledge of the normal spontaneous motor behavior of the human fetus during the second trimester of pregnancy. This study focuses on five patterns of spontaneous fetal movement: startle (S), axo-rhizomelic rhythmia (ARR), axial stretching (AS), general movement (GM), and diaphragmatic contraction (DC). METHODS A cohort of 13 subjects was followed up using 2D obstetrical ultrasound images at 12, 16, 20, and 24 weeks of gestation. As inclusion criteria, neonatal neurological examination and general movements after eutocic delivery at term were normal in all of the subjects, and their neuromotor and cognitive development until the end of pre-school age were also normal. RESULTS All these five motor patterns are present at the beginning of the 2(nd) gestational trimester, but their quantitative and qualitative traits are diverse according to gestational ages. The phasic, isolated or rhythmically repeated movements, S and ARR, are prominent at 12 and 16 weeks of gestation, and then their presence gradually diminishes. By contrast, tonic and complex AS and GM movements increase their presence and quality at 20 and 24 weeks. RAR constitute a particular periodic motor pattern not described in previous literature. Moreover, the incidence of DC is progressive throughout the trimester, in clusters of 2-6 arrhythmic and irregular beats. Fetal heart rate increases during fetal motor active periods. CONCLUSIONS All five normal behavioral patterns observed in the ultrasounds reflect the progressive tuning of motor generators in human nervous system during mid-pregnancy.

Abstract
OBJECTIVE To estimate the agreement between an expert and a non-expert examiner using the International Ovarian Tumor Analysis (IOTA) simple rules for classifying adnexal masses on real-time ultrasound and when using three-dimensional (3D) ultrasound volumes and digital clips. METHODS Forty-two non-consecutive women diagnosed as having an adnexal mass were evaluated by transvaginal power Doppler ultrasound as part of their diagnostic work-up. In each woman, examination was first performed by a non-expert examiner (a trainee) and immediately afterwards by an expert examiner. Both used the IOTA simple rules to describe the mass, blinded to each other's results. After finishing the examination, each examiner classified the mass as benign, malignant or inconclusive, according to the IOTA simple rules. Additionally, the expert recorded a short videoclip and acquired a static 3D volume of each mass, which were subsequently assessed by four trainees in obstetrics and gynecology with different levels of training, who also classified the mass as benign, malignant or inconclusive according to the IOTA simple rules. Agreement was assessed by calculating weighted and standard kappa index values with 95% CI and the percentage of agreement between observers. RESULTS Agreement between the observers who performed real-time ultrasound examination was good (weighted kappa = 0.76; 95% CI, 0.61-0.90; agreement = 78.6%). Agreement between trainees using videoclips plus 3D volumes was moderate (kappa values ranged from 0.45 to 0.58, depending on pair comparison). CONCLUSION Interobserver agreement of the IOTA simple rules for classifying adnexal masses as benign, malignant or inconclusive using real-time ultrasound, between an expert and a non-expert examiner, might be considered good. Agreement using a videoclip plus a 3D volume was moderate for trainees with different degrees of training.

Abstract
OBJECTIVE To determine the diagnostic performance of International Ovarian Tumor Analysis (IOTA) 'simple' rules for discriminating between benign and malignant adnexal masses. METHODS A prospective study was performed between January 2011 and June 2012. Eligible patients were women diagnosed with a persistent adnexal mass who presented to the participating centers. Four trainees evaluated the adnexal mass by transvaginal ultrasound under the supervision of an expert examiner. The trainee analyzed the mass according to IOTA simple rules and provided a diagnosis of benign, malignant or inconclusive. All women included in the study underwent surgery and tumor removal in the center of recruitment. Diagnostic performance was assessed by calculating sensitivity, specificity and positive (LR+) and negative (LR-) likelihood ratios. RESULTS A total of 340 women were included (mean patient age, 42.1 (range, 13-79) years). Of the tumors, 55 (16.2%) were malignant and 285 (83.8%) were benign. The IOTA simple rules could be applied in 270 (79.4%) cases. In these cases, sensitivity was 87.9% (95% CI, 72.4-95.2), specificity 97.5% (95% CI, 94.6-98.8), LR+ 34.7 (95% CI, 15.6-77.3) and LR- 0.12 (95% CI, 0.05-0.31). CONCLUSIONS Application of the IOTA simple rules yielded acceptable results in terms of specificity in the hands of non-expert examiners. However, with non-expert examiners there was a 12% false-negative rate, which is relatively high.

Abstract
OBJECTIVE To assess the feasibility of a specific training program for ultrasound diagnosis of adnexal masses. METHODS A 2-month intensive training program was developed. The program protocol consisted of a 1-day intensive theoretical course focused on clinical and sonographic issues related to adnexal masses and ovarian cancer, followed by a 4-week real-time ultrasound training program in a tertiary center (25-30 adnexal masses evaluated per month) and a final 4-week period for offline assessment of three-dimensional (3D) volumes from adnexal masses. In this final period, each trainee evaluated five sets of 100 3D volumes. 3D volumes contained gray-scale and power Doppler information, and the trainee was provided with clinical data for each case (patient age, menopausal status and reported symptoms). 3D volumes were obtained from surgically removed masses that had undergone histological diagnosis or from masses that had been followed up until resolution. After assessment of each set, the trainee's diagnostic performance was calculated (sensitivity and specificity) and each incorrectly classified mass was evaluated with the trainer. The objective was to achieve a sensitivity of > 95% and a specificity of > 90%. Learning curve cumulative summation (LC-CUSUM) graphs were plotted to assess the learning curve for the trainees. RESULTS One trainer and two trainees with little experience in gynecological ultrasound (one gynecologist and one radiologist) participated in this study. LC-CUSUM graphs showed that competence was achieved after 170 or 185 examinations. The objectives for diagnostic performance were achieved after assessment of the second set of 3D volumes (200 cases) for each trainee. CONCLUSIONS The proposed training program appears to be feasible. High diagnostic performance can be achieved after analysis of 200 cases and maintained thereafter.

Abstract
OBJECTIVE To evaluate the results of expectant management of ovarian cysts with benign ultrasound morphology in selected asymptomatic premenopausal women. METHODS This was a prospective cohort study of premenopausal women diagnosed with a persistent adnexal cyst. Patients were selected according to symptoms (asymptomatic), the cyst's appearance on ultrasound (benign) and size (< 8 cm). Patients underwent a follow-up protocol with transvaginal ultrasound examination at 6-monthly intervals for 2 years and then annually for at least 3 years. RESULTS The study comprised 166 women (mean age, 40 years) with 192 masses present at inclusion. Twenty-two women (with 29 masses) were lost to follow-up. Seventy-four masses (38.5%) resolved spontaneously (median time from diagnosis to resolution, 40 months). Forty-nine masses (25.5%) persisted without change (median follow-up time, 88 (range, 36-192) months). Forty masses (20.8%) were surgically removed; 12 because of increase in size, four because a second lesion appeared during follow-up, three because of change in appearance and increase in size, five because of surgery for uterine benign or malignant disease, two because of change in appearance without increase in size, one because of clinical suspicion of ovarian torsion and 13 because of the patient's decision in spite of there being no change in the mass. Histology was benign in all but two cases (Stage Ia mucinous ovarian carcinoma and Stage Ia mucinous borderline tumor). During follow-up 40 new masses in 31 women were diagnosed, of which 21 resolved spontaneously, five (all with benign histology) were surgically removed and 14 were still present at the time of writing. CONCLUSIONS Expectant management of cysts with benign ultrasound morphology is a management option in selected asymptomatic premenopausal women.

Abstract
OBJECTIVE To compare spatiotemporal image correlation-high definition flow (STIC-HDF) indices from spherical samples of ovary between women with polycystic ovary syndrome (PCOS) and normal women. METHODS This was a prospective case-control study of premenopausal women with a diagnosis of PCOS according to the Rotterdam criteria and of healthy, regularly menstruating, premenopausal women (controls) matched for age (< 35 years) and body mass index. Women were assessed in the follicular phase of the menstrual cycle by 4D STIC-HDF transvaginal ultrasound. Based on 1-cm(3) spherical sampling, we calculated for each woman the vascularization index (VI) for the most vascularized part of the ovarian stroma in all three-dimensional volumes of the 4D STIC-HDF sequence. The maximum (VI(sys)) and minimum (VI(diast)) values were assumed to represent systole and diastole, respectively, and the mean VI for all frames from one cardiac cycle was calculated. Based on these three VI values, we calculated the following indices: volumetric systolic/diastolic ratio (vS/D), volumetric resistance index (vRI) and volumetric pulsatility index (vPI), and compared them between study and control groups. RESULTS The study included 32 PCOS women (mean age, 29.6 years) and 32 controls (mean age, 30.4 years). Mean VI(sys) (26.246% vs 8.136%, P < 0.0001) and mean VI(diast) (22.242% vs 5.997%, P < 0.0001) were significantly higher in PCOS women compared with controls. Median vS/D (1.15 vs 1.33, P < 0.001), mean vRI (0.17 vs 0.30, P < 0.001) and median vPI (0.14 vs 0.28, P < 0.001) were significantly lower in PCOS women compared with controls. CONCLUSION 4D STIC-HDF indices from 1-cm(3) spherical samples of the ovaries were different between PCOS women and controls, suggesting lower impedance to flow in ovarian stromal vessels in PCOS women.

Abstract
OBJECTIVE To assess the clinical usefulness of a structured reporting system based on ultrasound findings for management of adnexal masses. METHODS This was a prospective multicenter study comprising 432 adnexal masses in 372 women (mean age, 44.0 (range, 13-78) years) over a 36-month period. Ninety-three (25%) women were postmenopausal and 279 (75%) women were premenopausal. Patients were evaluated with transvaginal ultrasound by one of three examiners expert in gynecological ultrasound. Reporting was provided to referring clinicians according to the Gynecologic Imaging Report and Data System (GI-RADS) classification. A predetermined management protocol was offered to referral clinicians. It was suggested that patients classified as GI-RADS 2 be managed with follow-up scan, patients classified as GI-RADS 3 undergo laparoscopic surgery and patients classified as GI-RADS 4 or 5 be referred to a gynecologic oncologist. Definitive histologic diagnosis was available in 370 cases and 62 additional cases were considered as benign because of spontaneous resolution during follow-up. These outcomes were used as the gold standard for calculating the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+) and negative likelihood ratio (LR-) of GI-RADS classification for identifying adnexal masses at high risk of malignancy, considering GI-RADS 4 and 5 as being malignant. RESULTS Of the 432 tumors, 112 were malignant and 320 benign. The GI-RADS classification rate was as follows: GI-RADS 2, 92 (21%) cases; GI-RADS 3, 184 (43%) cases; GI-RADS 4, 40 (9%) cases; GI-RADS 5, (27%) 116 cases. Sensitivity for this system was 99.1% (95% CI, 95.1-99.8%), specificity was 85.9% (95% CI, 81.7-89.3%), LR+ was 7.05 (95% CI, 5.37-9.45) and LR- was 0.01 (95% CI, 0.001-0.07). PPV and NPV were 71.1% and 99.6%, respectively. CONCLUSIONS The GI-RADS reporting system performed well in identifying adnexal masses at high risk of malignancy and seems to be useful for clinical decision-making.

Abstract
OBJECTIVE To assess the correlation between intratumoral vascularization using three-dimensional power Doppler angiography (3D-PDA) and several histological tumor characteristics in a series of patients with endometrial carcinoma. METHODS Ninety-nine women (mean age, 61.7 (range, 31-84) years) diagnosed as having endometrial cancer were assessed by transvaginal 3D-PDA before surgical staging. Endometrial volume (EV) and 3D-PDA vascular indices (vascularization index (VI), flow index (FI) and vascularization flow index (VFI)) were calculated using the Virtual Organ Computer-aided AnaLysis (VOCAL) method. All patients were surgically staged. Individual tumor features such as histological type, tumor grade, myometrial infiltration depth, lymph-vascular space involvement, cervical involvement, lymph node metastases and tumor stage were considered for analysis. Multivariate logistic regression (MLR) analysis was used to determine which 3D-PDA parameters were independently associated with each histological characteristic. RESULTS MLR analysis showed that only EV and VI were independently associated with myometrial infiltration (EV: odds ratio (OR), 1.119 (95% CI, 1.025-1.221), P = 0.012; VI: OR, 1.127 (95% CI, 1.063-1.195), P = 0.001) and tumor stage (EV: OR, 1.103 (95% CI, 1.012-1.202), P = 0.025; VI: OR, 1.120 (95% CI, 1.057-1.187), P = 0.001), only VI was independently associated with tumor grade (OR, 1.056 (95% CI, 1.023-1.091), P = 0.001) and only EV was independently associated with lymph node metastases (OR, 1.086 (95% CI, 1.017-1.161), P = 0.001). CONCLUSION 3D-PDA analysis of tumor vascularization in endometrial cancer correlates with some prognostic histological characteristics.

Abstract
OBJECTIVE To assess whether, when using spherical sampling with Virtual Organ Computer-Aided Analysis (VOCAL) for calculating three-dimensional (3D) power Doppler angiography (PDA) indices, the sphere volume affects performance in the prediction of malignancy in vascularized cystic-solid or solid adnexal masses. METHODS One hundred and thirty-eight women (mean +/- SD age, 51.8 +/- 14.1 years) diagnosed as having vascularized cystic-solid or solid adnexal masses on B-mode and two-dimensional (2D) power Doppler ultrasound were evaluated by 3D-PDA prior to surgery. Five women had bilateral masses, giving a total number of 143 masses analyzed. Vascularization was assessed using VOCAL software. 3D-PDA vascular indices (vascularization index (VI), flow index (FI) and vascularization flow index (VFI)) from the most vascularized area within papillary projections and solid areas were calculated automatically using spherical sampling. Five different volumes of sphere were used (1 cm(3), 2 cm(3), 3 cm(3), 4 cm(3) and 5 cm(3)) in each case. A definitive histological diagnosis was obtained in each case after surgical tumor removal. RESULTS One hundred and seventeen (82%) masses were malignant and 26 (18%) were benign. Morphological evaluation revealed 34 (24%) unilocular solid masses, 49 (34%) multilocular solid masses and 60 (42%) mostly solid masses. The 1-cm(3) sphere could be used in 100% of the cases, the 2-cm(3) sphere could be used in 98.2% of the cases and the 3-5-cm(3) spheres could be used in 97.2% of the cases. The median VI, FI and VFI for all sphere volumes were significantly higher in malignant compared with non-malignant tumors. Receiver-operating characteristics curve analysis showed that VI and VFI, independently of sphere volume, were better predictors of malignancy than was FI. The best cut-off values for the 3D-PDA indices differed depending on sphere volume. VI was significantly more specific than were VFI and FI. CONCLUSIONS Sphere volume does not affect the performance of 3D-PDA. We recommend the use of different cut-off values for 3D-PDA indices for discriminating between benign and malignant adnexal masses, depending on the sphere volume used. Use of VI is preferable due to its higher specificity.

Abstract
OBJECTIVE To assess whether the analysis of cyst content using mean gray value (MGV) can discriminate ovarian endometriomas from other unilocular ovarian cysts in premenopausal women. METHODS Stored three-dimensional (3D) volumes from 54 unilocular ovarian cysts diagnosed in 50 premenopausal women (mean age, 37 (range, 22-50) years) were analyzed to calculate the MGV from cyst content. Cysts with solid components or septations were excluded. MGV was calculated in all cases with the Virtual Organ Computer-aided AnaLysis technique. The B-mode presumptive diagnosis based on the examiner's subjective impression was also recorded. RESULTS Sixteen of the cysts resolved spontaneously and were given a final clinical diagnosis of hemorrhagic functional cyst, while 38 cysts were removed surgically (diagnosed histologically as seven simple cysts, three hemorrhagic cysts, 20 endometriomas, five mucinous cysts and three paraovarian cysts). B-mode diagnoses were as follows: seven simple cysts, 18 hemorrhagic cysts, 24 endometriomas, three mucinous cysts and two paraovarian cysts. MGV was significantly higher in ovarian endometrioma when compared with all other kinds of cyst. The receiver-operating characteristics curve showed that using an MGV cut-off >or= 15.560 had a sensitivity of 85% and a specificity of 76.5% for diagnosing ovarian endometrioma (area under the curve, 0.831; 95% CI, 0.718-0.944). These figures were similar to those for B-mode diagnosis (sensitivity, 90%; specificity, 82%) (McNemar test, P = 1.000). Combining B-mode and MGV gave a sensitivity of 80% and a specificity of 91%. CONCLUSION Cyst content MGV is higher in ovarian endometrioma than it is in other unilocular ovarian cysts. The diagnostic performance of MGV is similar to that of the examiner's subjective impression. The combination of both criteria achieves the highest specificity.

Abstract
There are no sufficiently sensitive and specific signs and symptoms or diagnostic tests for the clinical diagnosis of endometriosis, and no diagnostic strategy is supported by evidence of effectiveness. Pelvic and rectal examinations should be performed, although the yield of the physical examination is low. Laboratory tests and radiological examinations are usually not warranted. Measurement of CA 125 levels may be useful for monitoring disease progress, and MRI has a high sensitivity in detecting endometrial cysts but poor diagnostic accuracy for endometriosis in general. Patients with persistent symptoms after empirical treatment should be referred for laparoscopy, the preferred method for diagnosis of endometriosis.

Abstract
Abnormal thickening of the Endometrial Subendometrial Myometrium Unit (ESEMy Unit, including basal endometrium and inner myometrium) has been detected on imaging and referred to as "diffuse adenomyosis" in infertile patients with proven endometriosis. However, no robust relationship exists between enlargement of the ESEMy Unit and adenomyosis proven on hysterectomy specimen examination; moreover, if any correlation exists, it lacks histological validation in women wishing to preserve fertility. While adenomyosis effects on fertility, if any, remain elusive, thickening of the ESEMy Unit have been consistently linked to fertility impairment in both experimental and clinical models. The hypothesis tested herein is that a novel condition exists, called "ESEMy Unit disruption disease"; it is epidemiologically different from adenomyosis, diagnosable on imaging and bears a clear impact on human fertility through various mechanisms. A new wave of good quality studies may be elicited by a clear distinction between adenomyosis and the "ESEMy Unit disruption disease".

Abstract
Endometriosis is a common gynaecological disease of unknown aetiology. Angiogenesis appears to be one of the processes involved in its pathogenesis. Angiogenic factors are increased in the peritoneal fluid of patients with endometriosis (McLaren 1996 et al; Taylor et al, 2002), in peritoneal implants (Ferriani et al, 1993) and in ovarian endometriomas. On the other hand, some researchers have found that angiogenesis is related to pelvic pain. We speculated that ovarian endometriomas in patients presenting with pelvic pain would be more angiogenic than those in asymptomatic women and that their vascular features would therefore be different.

Abstract
OBJECTIVE To analyze two different methods for performing three-dimensional power Doppler angiography (3D-PDA) vascular sampling in solid and cystic-solid adnexal masses. METHODS Twenty-one 3D-PDA volumes from 18 consecutive and unselected solid or cystic-solid adnexal masses (13 malignant and five benign) were analyzed. A single examiner (J. L. A.) acquired all the volumes according to a predetermined scanning protocol. Two different observers (one inexperienced and the other experienced) calculated 3D-PDA vascular indices (vascularization index (VI), flow index (FI) and vascularization flow index (VFI)) from solid tumor areas. First, manual sampling (Plane A, 15 degrees rotation-step) was performed, and 1 week later 5-cm(3) sphere sampling from the most vascularized area was carried out. The observers made a record of any difficulty that they encountered in delineating the solid areas of tumors or in distinguishing true tumor vessels from pre-existing vessels, the time spent performing each analysis was recorded and inter- and intraobserver reproducibility was evaluated for each method using intraclass correlation coefficients (ICC). RESULTS In four (19.0%) of the 21 volumes sphere sampling could not be performed because it was not possible to obtain a sphere smaller than 5.5 cm(3). This happened in cases in which image zooming was used when acquiring the 3D volume. The inexperienced observer encountered more difficulty, but not significantly more, than the experienced observer when analyzing 3D-PDA volumes both by manual sampling (29% vs. 14% of cases) and 5-cm(3) sphere sampling (35% vs. 18% of cases). The mean time spent by the inexperienced observer was significantly greater (P < 0.001) than that spent by the experienced observer both for manual sampling (6.11 min vs. 1.85 min) and 5-cm(3) sphere sampling (2.93 min vs. 2.15 min). Contrary to the findings for the experienced observer, the inexperienced observer required less time to perform sphere sampling than they did manual sampling. Interobserver agreement was high for both methods: ICC for manual volume, 0.993; manual VI, 0.908; manual FI, 0.913; manual VFI, 0.914; sphere volume, 0.949; sphere VI, 0.954; sphere FI 0.850; and sphere VFI, 0.953. Intraobserver reproducibility was also high, with all ICCs above 0.99. CONCLUSIONS Manual and 5-cm(3) sphere sampling are reproducible methods for 3D-PDA vascular sampling. Caution is required when image zoom is used at the time of acquiring the volume because this may prevent sphere sampling. Difficulties found in performing both manual and sphere sampling do not seem to significantly affect the reproducibility of Doppler index calculations.

Abstract
OBJECTIVES To prospectively evaluate an ultrasound-based scoring system as a method for triaging asymptomatic women presenting with an adnexal mass for surgical treatment. METHODS Two hundred and four adnexal masses in 189 asymptomatic women undergoing elective surgical treatment at our institution were included in this prospective study. Patients were evaluated by transvaginal power Doppler ultrasound imaging before surgery. Patients were classified as low risk or high risk for malignancy according to an ultrasound-based scoring system. Women with a low risk for malignancy were scheduled for laparoscopy and patients with a high risk for malignancy were scheduled for laparotomy. However, patients classified as low risk by the ultrasound scoring system, but with a tumor size >or= 10 cm or clinical suspicion of pelvic adhesions, were instead considered to be at intermediate risk and were scheduled for laparotomy. Some patients classified as high risk were scheduled for an operative laparoscopy by an expert in gynecological oncology. RESULTS One hundred and thirty-four (65.7%) masses were considered to be low risk and were treated by a laparoscopically guided procedure. All these tumors were benign. Forty-seven (23%) masses were classified as high risk, of which 39 tumors were malignant and eight benign. Twenty-three (11.3%) tumors were considered to be intermediate risk and were scheduled for primary laparotomy. In this group, 21 (91.3%) tumors proved to be benign and two (8.7%) were malignant. CONCLUSIONS Ultrasound-based triage of asymptomatic women diagnosed with a persistent adnexal mass is effective for selecting the surgical approach.

Abstract
OBJECTIVE To evaluate tumor vascularity by three-dimensional power Doppler ultrasound (3D-PDU) in early and advanced stage primary ovarian cancers and in metastatic tumors to the ovary. PATIENTS AND METHODS This was a retrospective analysis of clinical and sonographic data from 49 women with primary ovarian cancers or metastatic tumors to the ovary. All women underwent 3D-PDU prior to surgery. Vascularization index (VI), flow index (FI) and vascularization flow index (VFI) from solid portions or papillary projections in the tumors were calculated using the Virtual Organ Computer-aided AnaLysis (VOCAL(trade mark)) program. Definitive histological diagnosis was obtained in each case. RESULTS Among the 49 women, 10 had stage I primary cancers (five low-malignant potential tumors and five invasive tumors), 26 had advanced stage primary ovarian cancers and 13 had metastatic tumors to the ovary. Mean VI and VFI were significantly higher in advanced stage tumors and metastatic tumors as compared with early stage tumors. No differences in 3D-PDU indices were found between advanced stage and metastatic cancers. CONCLUSIONS Vascular indices derived from 3D-PDU tend to be higher in advanced stage and metastatic ovarian cancers as compared with early stage ovarian tumors.

Abstract
In pregnancy there occurs maternal tolerance to the foetus. Several mechanisms have been proposed to explain this phenomenon. The main immune population in the decidua are macrophages and natural killer cells, but with some "special" suppressor characteristics. There is also a predominant TH2 response. The non classical MCH type I HLA-G is expressed by trophoblasts and can suppress lymphomononuclear cytotoxicity. Other system to avoid the immune system is the expression of indoleamine-2,3-dioxygenase, that suppresses T cell activation by degrading tryptophan. Even though in the placenta there is a high production of nitric oxide, a well-known immune modulator, low attention has been paid to its role in maternal tolerance. There are many data showing that NO affects the IDO, CD95/CD95-L and the balance between TH1/TH2. Maybe NO could interact with several mechanisms at the same time, which could modify the tolerogenic activity depending on the concentration and the presence of other factors in the medium.

Abstract
The objective of this study was to evaluate whether intratumoral blood flow as assessed by transvaginal color Doppler ultrasonography (TVCD) correlates with some tumor features in cervical cancer. Clinical, sonographic, and histologic data on 49 women (mean age: 50.3 years, range: 25-85 years) diagnosed as having a carcinoma from the uterine cervix were reviewed. Intratumoral blood flow was assessed by TVCD in all cases. Subjective impression of the amount of flow (scanty, moderate, or abundant) as well as the lowest resistance index (RI) and highest peak systolic velocity (PSV, cm/s) were used for analysis. These data were correlated with some tumoral features such as histologic type, histologic grade, tumor volume, and tumor stage. Intratumoral blood flow was found in all cases. Abundant blood flow was found more frequently in squamous carcinoma, moderately or poorly differentiated tumors, tumors with larger volume, and advanced stage tumors (P < 0.0001). Significantly lower RI was found in moderately or poorly differentiated tumors and advanced stage tumors (P < 0.01) and significantly higher PSV was found in moderately or poorly differentiated tumors, tumors with larger volume, and advanced stage tumors (P < 0.01). No correlation was found between RI and PSV and histologic type. Our data indicate that intratumoral blood flow as assessed by TVCD correlates well with some tumor features in cervical cancer.

Abstract
OBJECTIVE To evaluate the role of transvaginal power Doppler sonography to discriminate between benign and malignant endometrial conditions in women presenting with postmenopausal bleeding and thickened endometrium at baseline sonography. METHODS Ninety-one postmenopausal women (median age, 58 years; range, 47-83 years) presenting with uterine bleeding and a thickened endometrium (> or = 5-mm double-layer endometrial thickness) on transvaginal sonography were included in this prospective study. Endometrial blood flow distribution was assessed in all patients by power Doppler immediately after B-mode transvaginal sonography. Three different vascular patterns were defined: Pattern A: multiple-vessel pattern, Pattern B: single-vessel pattern and Pattern C: scattered-vessel pattern. Histological diagnoses were obtained in all cases. No patient taking tamoxifen citrate or receiving hormone replacement therapy was included. RESULTS Histological diagnoses were as follows: endometrial cancer: 33 (36%), endometrial polyp: 37 (41%), endometrial hyperplasia: 14 (15%), endometrial cystic atrophy: 7 (8%). Blood flow was found in 97%, 92%, 79% and 85% of cases of carcinoma, polyp, hyperplasia and endometrial cystic atrophy, respectively. A total of 81.3% of vascularized endometrial cancers showed Pattern A, 97.1% of vascularized polyps exhibited Pattern B and 72.7% of vascularized hyperplasias showed Pattern C. Sensitivity and specificity for endometrial cancer were 78.8% and 100%. For endometrial polyp these respective values were 89.2% and 87% and for hyperplasia they were 57.1% and 88.3%. CONCLUSIONS Transvaginal power Doppler blood flow mapping is useful to differentiate benign from malignant endometrial pathology in women presenting with postmenopausal bleeding and thickened endometrium at baseline sonography.

Abstract
BACKGROUND The aim of this investigation was to correlate ovarian endometrioma vascularization with the presence of pelvic pain. METHODS The presence of blood flow, peak systolic velocity (PSV, cm/s) and lowest pulsatility index (PI), assessed by transvaginal colour Doppler ultrasonography and CA-125 plasma concentrations, were retrospectively analysed in 74 patients who had undergone operations for cystic ovarian endometriosis. Fifty-two patients were asymptomatic (group A) and 22 presented with pelvic pain (group B). There were 56 endometriomas in group A and 26 in group B. RESULTS Blood flow was found in 66.1 and 88.5% of endometriomas in groups A and B respectively (P = 0.036). PI was significantly lower (P = 0.009) and CA-125 concentration higher (P = 0.0004) in group B. There were no differences in PSV. CONCLUSIONS We conclude that vascularization of ovarian endometriomas in patients presenting with pelvic pain is higher than in asymptomatic patients. This could be an indicator of endometriosis activity.

Abstract
OBJECTIVE To assess a new logistic regression model developed to predict malignancy in adnexal masses. METHODS In the first part of this study, we developed a logistic model by applying logistic regression analysis in a series of 268 adnexal masses (203 benign and 65 malignant lesions) in 248 patients (mean age, 43.6 years; SD, 14.2 years) evaluated and treated at our institution. Eleven parameters were entered in the logistic regression analysis in a forward stepwise way. In the second part of the study, we evaluated the model's diagnostic performance in a further set of 135 adnexal masses (103 benign and 32 malignant tumors) in 129 patients (mean age, 44.4 years; SD, 14.6 years). This diagnostic performance was compared with that of age, tumor volume, Sassone's and Ferrazzi's B-mode ultrasonographic morphologic scoring systems, serum cancer antigen 125 level, and the tumor's lowest resistive index. Comparison was done by calculating the area under the receiver operating characteristic curve. RESULTS In logistic analysis, only menopausal status, the presence of papillary projections, the logarithm of the cancer antigen 125 value, tumor blood flow location, and the lowest resistive index were retained in the model. The model had the best area under the curve (0.97), significantly higher than patient age (area under the curve, 0.78; P = .001), tumor volume (area under the curve, 0.68; P < .0001), cancer antigen 125 (area under the curve, 0.88; P = .008), lowest resistive index (area under the curve, 0.85; P = .011), Ferrazzi's scoring system (area under the curve, 0.89; P = .01), and maximal peak systolic velocity (area under the curve, 0.71; P< .0001). Comparison with Sassone's scoring system (area under the curve, 0.91) did not reach statistical significance, but a clear trend was found (P = .116). CONCLUSIONS The model had the best diagnostic performance for discriminating between benign and malignant adnexal masses. A clinical prospective evaluation is needed to confirm its actual value.

Abstract
OBJECTIVE To describe the sonographic characteristics of ovarian cystadenofibromas. METHODS We conducted a retrospective study of 23 ovarian tumors histopathologically confirmed as ovarian cystadenofibromas that were preoperatively evaluated by transvaginal color Doppler sonography. RESULTS In all cases the mass was predominantly cystic. Septations appeared in 30.4% of the tumors. Papillary projections or solid nodules appeared in 56.5% of the cases. The most frequent appearance was a unilocular complex cystic mass. In 47.8% of the tumors, vascularization was detected, having a typical pattern of peripheral vascularization with scattered vessels of high blood flow impedance. CONCLUSIONS We have described the sonographic spectrum of findings of ovarian cystadenofibromas. The most frequent appearance was a unilocular cystic mass with gross papillary projections or solid nodules. In almost half of the tumors, vascularization could be detected.

Abstract
OBJECTIVE To analyze the usefulness of transvaginal color Doppler assessment of venous flow in the differential diagnosis of adnexal masses. MATERIAL AND METHODS Ninety-one consecutive patients (mean age: 46.6 years, range: 16-81 years) diagnosed as having an adnexal mass were evaluated by transvaginal color Doppler sonography prior to surgery. Color Doppler was used to detect and analyze the flow velocity waveform from arterial and venous blood flow within the tumor. For arterial signals the resistance index and peak systolic velocity, and for veins the maximum venous flow velocity, were calculated. Receiver operator characteristic curves were plotted to determine the best venous flow velocity cut-off. According to our previous study using arterial Doppler, a tumor was considered as malignant when flow was detected and the lowest resistance index was < or = 0.45. Using venous Doppler a mass was considered as malignant when flow was detected and the venous flow velocity was > or = the best cut-off found on the receiver operator characteristic curve. Definitive histopathological diagnosis was obtained in all cases. Sensitivity, specificity, positive predictive value and negative predictive value for B-mode morphology (evaluation performed according to Sassone's scoring system), arterial Doppler, venous Doppler, and a combination of both arterial and venous Doppler were calculated. RESULTS Twenty-five masses (27.5%) were malignant and 66 (72.5%) benign. Arterial and venous flow was found more frequently in malignant than in benign masses (92% vs. 41% (P < 0.001) and 72% vs. 21% (P < 0.001), respectively). The resistance index was significantly lower in malignant tumors (0.42 vs. 0.60, P = 0.0003). No differences were found in peak systolic velocity. Venous flow velocity was significantly higher in malignant masses (18.1 cm/s vs. 8.9 cm/s, P = 0.0006). The best cut-off of venous flow velocity was 10 cm/s. Sensitivity, specificity, positive predictive value and negative predictive value for morphology, arterial Doppler, venous Doppler, and the combination of both arterial and venous Doppler were 92%, 71%, 45%, 96%; 76%, 95%, 87%, 91%; 68%, 94%, 81%, 89%; and 88%, 91%, 79%, 95%, respectively. CONCLUSIONS Our results indicate that preoperative evaluation by venous flow assessment of adnexal masses may be useful to discriminate between malignant and benign tumors.

Abstract
PURPOSE The purpose of this study was to analyze our experience with the influence of reconstructive techniques at the time of pelvic exenteration on morbidity. MATERIALS AND METHODS Between June 1986 and December 1998, 60 pelvic exenterations for gynecologic malignancies were performed in our hospital. Forty-five were selected for this study because they met two criteria: they were performed by the same team (gynecologic oncologist), and they had similar primary tumors. There were 38 cervical, 2 vaginal, and 5 uterine malignancies. Sixteen patients underwent reconstructive surgery: 11 (68.8%) with placement of a myocutaneous flap with left rectus abdominis, 3 (18.8%) with gracilis muscle, and 2 (12.5%) with the Singapore fasciocutaneous flap. Twenty-nine patients had no reconstruction. Records were reviewed and statistical analysis was performed. RESULTS Attachment of the grafts was complete in 14 of 16 (87.5%), with a partial vulvovaginal dehiscence in 2 cases. Morbidities included secondary infection in 3 (18.8%), partial necrosis in 3 (18.8%), and partial stenosis in 5 (31.6%); the last was significantly associated with a gracilis flap (P = 0.015). There were no statistical differences between neovagina and nonneovagina groups with respect to the rate of fever, small bowel fistula, bowel obstruction, wound infection or dehiscence, hernia, colorectal leak, colostomy or urostomy prolapse, deep vein thrombosis, pulmonary embolism, intraoperative blood transfusions, or hospital stay. There were no pelvic abscesses in the neovagina group compared with 27% (6/29) in the other group (P = 0.050). Surgery was significantly longer (P = 0.019) for the reconstructive surgery group, with no statistical difference between different kinds of flaps. There were no deaths in either group. CONCLUSIONS Reconstruction of the vagina and pelvic floor at the time of pelvic exenteration can be done safely. Although this increases surgical time, morbidity is not significantly increased. The rectus abdominis flap seems to be the preferable option for primary vaginal and pelvic floor reconstruction.

Abstract
PURPOSE In this retrospective study, the sonographically measured endometrial thickness in asymptomatic, hypertensive postmenopausal women was compared with that in normotensive postmenopausal women. METHODS We reviewed clinical and sonographic data on 511 consecutive, unselected, asymptomatic postmenopausal women who attended our hospital for routine gynecologic examinations during a 6-month period. Two hundred nineteen patients (mean age, 60.2 years; age range, 49-81 years) were included in the study. Reasons for exclusion were: clinical data about hypertension were not available (n = 159); the patient had received or was receiving hormonal treatment (n = 78); the patient had undergone a hysterectomy (n = 25); and endometrial thickness could not be determined (n = 30). All patients had been examined using transvaginal or transabdominal sonography. Endometrial thickness was measured at the level of its maximum thickness in the uterine sagittal plane. RESULTS Fifty-six (26%) of 219 patients were hypertensive. Of these 56 patients, 41 (73%) were receiving drug treatment. The mean endometrial thickness in the hypertensive patients receiving treatment [6.2 mm; 95% confidence interval (CI), 5.1-7.4 mm] was significantly greater than in both the untreated, hypertensive patients (4.3 mm; 95% CI, 3.1-5. 5 mm) (p = 0.008) and the normotensive patients (3.6 mm; 95% CI, 3. 4-3.8 mm) (p < 0.0001). Endometrial thickness was equal to or greater than 5 mm in 59% of the hypertensive patients receiving drug treatment compared with 40% of the untreated, hypertensive patients and 18% of the normotensive patients (p < 0.001). An endometrial stripe was sonographically detected in 22% of the hypertensive patients undergoing treatment, 7% of the hypertensive patients undergoing no treatment, and 1% of the normotensive patients (p < 0. 0001). CONCLUSIONS Our data indicate that endometrial thickness, which can be determined sonographically, is frequently greater in asymptomatic, hypertensive postmenopausal women receiving antihypertensive drugs than in untreated hypertensive and normotensive patients. This conclusion could have clinical relevance when interpreting endometrial sonographic findings in asymptomatic, hypertensive postmenopausal patients.

Abstract
BACKGROUND To assess the risk of malignant cells dissemination in patients with endometrial cancer undergoing saline infusion sonohysterography (SIS). METHODS Fourteen consecutive patients (mean age: 58.1 years, range: 41-74 years) diagnosed as having a clinical stage I endometrial carcinoma and scheduled for surgical staging were entered in this study. SIS was performed at the time of laparotomy just when the abdomen was opened and prior to the start of the surgical procedure. 10-20 mL of saline was infused. All fluid spilled from the fimbrial ends of the fallopian tubes was collected and analyzed for the presence or absence of malignant endometrial cells. Samplings were also taken from ascites, if found, or cytological washings, prior to and after SIS. RESULTS SIS could be satisfactorily performed in all patients. There was no spillage from either tube in nine patients. Mean fluid volume obtained from the other five patients was 4.4 mL. Cytologic analysis revealed the presence of malignant cells in the spilled fluid in one case (7.1%, one out of fourteen). CONCLUSIONS Our data show that a small but real risk of malignant cell dissemination exists in patients with endometrial carcinoma who undergo SIS.
