Oocyte diameter predicts the maturation rate of human immature oocytes collected ex vivo. J Assist Reprod Genet 2022; 39:2209-2214. [PMID: 36087150 PMCID: PMC9596637 DOI: 10.1007/s10815-022-02602-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 08/19/2022] [Indexed: 11/29/2022] Open
Abstract
Purpose To study the impact of oocyte diameter and cumulus cell mass on the potential for final maturation of immature human oocytes in vitro. Methods Immature oocytes (n = 1563) from 75 women undergoing fertility preservation by ovarian tissue cryopreservation (14–41 years) were collected. After preparation of the ovarian cortex for freezing, immature oocytes were collected from the surplus medulla. After collection, IVM was performed according to standard published methods. The mass of cumulus cell surrounding the immature oocyte was grouped according to size. After IVM, each oocyte was photographed, measured, and the diameter was calculated as a mean of two perpendicular measurements. Results The diameter of the oocytes ranged from 60 to 171 µm with a mean of 115 µm (SD:12.1) and an interquartile range from 107 to 124 µm. The oocyte diameter was positively associated with a higher incidence of MII (p < 0.001). MII oocytes had a significantly larger mean diameter than MI, GV, and degenerated oocytes. The size of the cumulus cell mass was significantly associated with the MII stage (p < 0.001) and larger oocyte diameter (p < 0.001). The results further confirm that the diameter of the fully grown oocyte is reached relatively early in human follicular development and that the factors governing oocyte maturation in vitro are connected to the surrounding cell mass and the oocyte. Conclusion The diameter of the oocyte is a highly determining factor in the nuclear maturation of the human oocyte during in vitro maturation, and the size of the cumulus cell mass is closely positively associated with a larger diameter.

Development of a core outcome set and outcome definitions for studies on uterus-sparing treatments of adenomyosis (COSAR): an international multistakeholder-modified Delphi consensus study. Hum Reprod 2022; 37:2012-2031. [PMID: 35906919 PMCID: PMC9433836 DOI: 10.1093/humrep/deac166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 06/11/2022] [Indexed: 11/25/2022] Open
Abstract
STUDY QUESTION What outcomes should be reported in all studies investigating uterus-sparing interventions for treating uterine adenomyosis? SUMMARY ANSWER We identified 24 specific and 26 generic core outcomes in nine domains. WHAT IS KNOWN ALREADY Research reporting adenomyosis treatment is not patient-centred and shows wide variation in outcome selection, definition, reporting and measurement of quality. STUDY DESIGN, SIZE, DURATION An international consensus development process was performed between March and December 2021. Participants in round one were 150 healthcare professionals, 17 researchers and 334 individuals or partners with lived experience of adenomyosis from 48 high-, middle- and low-income countries. There were 291 participants in the second round. PARTICIPANTS/MATERIALS, SETTING, METHODS Stakeholders included active researchers in the field, healthcare professionals involved in diagnosis and treatment, and people and their partners with lived experience of adenomyosis. The core component of the process was a 2-step modified Delphi electronic survey. The Steering Committee analysed the results and created the final core outcome set (COS) in a semi-structured meeting. MAIN RESULTS AND THE ROLE OF CHANCE A total of 241 outcomes was identified and distilled into a ‘long list’ of 71 potential outcomes. The final COS comprises 24 specific and 26 generic core outcomes across nine domains, including pain, uterine bleeding, reproductive outcomes, haematology, urinary system, life impact, delivery of care, adverse events and reporting items, all with definitions provided by the Steering Committee. Nineteen of these outcomes will apply only to certain study types. Although not included in the COS, the Steering Committee recommended that three health economic outcomes should be recorded. LIMITATIONS, REASONS FOR CAUTION Patients from continents other than Europe were under-represented in this survey. A lack of translation of the survey might have limited the active participation of people in non-English speaking countries. Only 58% of participants returned to round two, but analysis did not indicate attrition bias. There is a significant lack of scientific evidence regarding which symptoms are caused by adenomyosis and when they are related to other co-existent disorders such as endometriosis. As future research provides more clarity, the appropriate review and revision of the COS will be necessary. WIDER IMPLICATIONS OF THE FINDINGS Implementing this COS in future studies on the treatment of adenomyosis will improve the quality of reporting and aid evidence synthesis.

Consensus on revised definitions of Morphological Uterus Sonographic Assessment (MUSA) features of adenomyosis: results of modified Delphi procedure. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2022; 60:118-131. [PMID: 34587658 PMCID: PMC9328356 DOI: 10.1002/uog.24786] [Citation(s) in RCA: 64] [Impact Index Per Article: 32.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 08/18/2021] [Accepted: 09/16/2021] [Indexed: 05/13/2023]
Abstract
OBJECTIVES To evaluate whether the Morphological Uterus Sonographic Assessment (MUSA) features of adenomyosis need to be better defined and, if deemed necessary, to reach consensus on the updated definitions. METHODS A modified Delphi procedure was performed among European gynecologists with expertise in ultrasound diagnosis of adenomyosis. To identify MUSA features that might need revision, 15 two-dimensional (2D) video recordings (four recordings also included three-dimensional (3D) still images) of transvaginal ultrasound (TVS) examinations of the uterus were presented in the first Delphi round (online questionnaire). Experts were asked to confirm or refute the presence of each of the nine MUSA features of adenomyosis (described in the original MUSA consensus statement) in each of the 15 videoclips and to provide comments. In the second Delphi round (online questionnaire), the results of the first round and suggestions for revision of MUSA features were shared with the experts before they were asked to assess a new set of 2D and 3D still images of TVS examinations and to provide feedback on the proposed revisions. A third Delphi round (virtual group meeting) was conducted to discuss and reach final consensus on revised definitions of MUSA features. Consensus was predefined as at least 66.7% agreement between experts. RESULTS Of 18 invited experts, 16 agreed to participate in the Delphi procedure. Eleven experts completed and four experts partly finished the first round. The experts identified a need for more detailed definitions of some MUSA features. They recommended use of 3D ultrasound to optimize visualization of the junctional zone. Fifteen experts participated in the second round and reached consensus on the presence or absence of ultrasound features of adenomyosis in most of the still images. Consensus was reached for all revised definitions except those for subendometrial lines and buds and interrupted junctional zone. Thirteen experts joined the online meeting, in which they discussed and agreed on final revisions of the MUSA definitions. There was consensus on the need to distinguish between direct features of adenomyosis, i.e. features indicating presence of ectopic endometrial tissue in the myometrium, and indirect features, i.e. features reflecting changes in the myometrium secondary to presence of endometrial tissue in the myometrium. Myometrial cysts, hyperechogenic islands and echogenic subendometrial lines and buds were classified unanimously as direct features of adenomyosis. Globular uterus, asymmetrical myometrial thickening, fan-shaped shadowing, translesional vascularity, irregular junctional zone and interrupted junctional zone were classified as indirect features of adenomyosis. CONCLUSION Consensus between gynecologists with expertise in ultrasound diagnosis of adenomyosis was achieved regarding revised definitions of the MUSA features of adenomyosis and on the classification of MUSA features as direct or indirect signs of adenomyosis. © 2021 The Authors.

Definition and sonographic reporting system for Cesarean scar pregnancy in early gestation: modified Delphi method. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2022; 59:437-449. [PMID: 34779085 PMCID: PMC9322566 DOI: 10.1002/uog.24815] [Citation(s) in RCA: 34] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 10/30/2021] [Accepted: 11/05/2021] [Indexed: 05/10/2023]
Abstract
OBJECTIVE To develop a standardized sonographic evaluation and reporting system for Cesarean scar pregnancy (CSP) in the first trimester, for use by both general gynecology and expert clinics. METHODS A modified Delphi procedure was carried out, in which 28 international experts in obstetric and gynecological ultrasonography were invited to participate. Extensive experience in the use of ultrasound to evaluate Cesarean section (CS) scars in early pregnancy and/or publications concerning CSP or niche evaluation was required to participate. Relevant items for the detection and evaluation of CSP were determined based on the results of a literature search. Consensus was predefined as a level of agreement of at least 70% for each item, and a minimum of three Delphi rounds were planned (two online questionnaires and one group meeting). RESULTS Sixteen experts participated in the Delphi study and four Delphi rounds were performed. In total, 58 items were determined to be relevant. We differentiated between basic measurements to be performed in general practice and advanced measurements for expert centers or for research purposes. The panel also formulated advice on indications for referral to an expert clinic. Consensus was reached for all 58 items on the definition, terminology, relevant items for evaluation and reporting of CSP. It was recommended that the first CS scar evaluation to determine the location of the pregnancy should be performed at 6-7 weeks' gestation using transvaginal ultrasound. The use of magnetic resonance imaging was not considered to add value in the diagnosis of CSP. A CSP was defined as a pregnancy with implantation in, or in close contact with, the niche. The experts agreed that a CSP can occur only when a niche is present and not in relation to a healed CS scar. Relevant sonographic items to record included gestational sac (GS) size, vascularity, location in relation to the uterine vessels, thickness of the residual myometrium and location of the pregnancy in relation to the uterine cavity and serosa. According to its location, a CSP can be classified as: (1) CSP in which the largest part of the GS protrudes towards the uterine cavity; (2) CSP in which the largest part of the GS is embedded in the myometrium but does not cross the serosal contour; and (3) CSP in which the GS is partially located beyond the outer contour of the cervix or uterus. The type of CSP may change with advancing gestation. Future studies are needed to validate this reporting system and the value of the different CSP types. CONCLUSION Consensus was achieved among experts regarding the sonographic evaluation and reporting of CSP in the first trimester. © 2021 The Authors.

Hormonal response in patients transplanted with cryopreserved ovarian tissue is independent of whether freezing was performed in childhood or adulthood. J Assist Reprod Genet 2021; 38:3039-3045. [PMID: 34617199 DOI: 10.1007/s10815-021-02320-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Accepted: 09/10/2021] [Indexed: 12/23/2022] Open
Abstract
PURPOSE This study evaluated the concentrations of hormones resulting from the transplantation of ovarian tissue (OTT) in relation to whether the tissue was frozen at a time close to puberty or above the age of 19 years. METHODS Six girls and adolescents (aged 9-14 years) who underwent ovarian tissue cryopreservation (OTC) were followed after transplantation in adulthood. After OTT, the women were followed via regular blood samples to evaluate the concentrations of FSH, LH, oestradiol and AMH. Twenty-three women undergoing OTT (aged 19-36 years at the time of OTC) were included as a reference group. All of the women had postmenopausal levels of gonadotropins at the time of transplantation. RESULTS The return of FSH and LH to normal premenopausal concentrations in adult women transplanted with ovarian tissue that was frozen at a time close to puberty was similar to the profiles in women from the reference group. Serum AMH levels were below the detection limit (via the Roche Elecsys assay) in many samples, but four out of six young girls showed measurable concentrations. Oestradiol similarly increased in the first 12 weeks following transplantation, after which it tended to be higher in women having frozen tissue in adulthood. CONCLUSIONS Ovarian tissue that was excised from girls at a time close to puberty, after which it was frozen and transplanted in adulthood, interacts with pituitary tissue in a similar manner to ovarian tissue that is frozen from adult women. Follicles located in the ovarian tissue from young girls are equally sensitive to gonadotropin stimulation as follicles from adult women when exposed to postmenopausal levels of gonadotropins. This result indicates that it is not the ovaries that require maturation to sustain full reproductive potential but rather proper FSH and LH stimulation. Moreover, these results support the continued use of OTC in young women.

Abstract
OBJECTIVES To derive and validate a practical scoring system for identification of endometrial cancer (EC) or atypical hyperplasia (AH) using transvaginal ultrasonography (TVS) and gel infusion sonography (GIS) in women with postmenopausal bleeding (PMB). STUDY DESIGN Endometrial pattern was correlated with endometrial pathology in consecutive women with PMB in both a derivation study (N = 164) and a validation study (N = 711). Logistic regression was used to derive and validate two scoring systems (A and B) for prediction of EC/AH: scoring system A was Doppler score + interrupted endo-myometrial junction (IEJ) (2 points); and scoring system B was Doppler score + IEJ (1 point) + Irregular Endometrial Outline (IESO) by GIS (1 point); the Doppler score was based on the presence of more than one single or double vessel (1 point) + multiple vessels (1 point) + large vessels (1 point). OUTCOME MEASURES Diagnostic performance and calibration curves for identification of EC/AH. RESULTS Both scoring systems had good observer agreement. VALIDATION DATA Scoring was most effective with endometrial thickness (ET) ≥ 8 mm. Both scoring systems were well calibrated and performed satisfactorily in women with ET ≥ 8 mm. The sensitivity and specificity of a score of ≥ 2 points in system A were 92% and 84%; the respective values were 89% and 88% in system B. CONCLUSIONS Scoring was highly efficient in identifying EC/AH. Four risk groups of EC/AH may guide the management of women with PMB: very low (ET < 4 mm), low (ET 4-7.9 mm), intermediate (ET ≥ 8 mm and score < 2 points) and high risk (ET ≥ 8 mm and score ≥ 2 points).

Abstract
OBJECTIVE To generate guidance for detailed uterine niche evaluation by ultrasonography in the non-pregnant woman, using a modified Delphi procedure amongst European experts. METHODS Twenty gynecological experts were approached through their membership of the European Niche Taskforce. All experts were physicians with extensive experience in niche evaluation in clinical practice and/or authors of niche publications. By means of a modified Delphi procedure, relevant items for niche measurement were determined based on the results of a literature search and recommendations of a focus group of six Dutch experts. It was predetermined that at least three Delphi rounds would be performed (two online questionnaires completed by the expert panel and one group meeting). For it to be declared that consensus had been reached, a consensus rate for each item of at least 70% was predefined. RESULTS Fifteen experts participated in the Delphi procedure. Consensus was reached for all 42 items on niche evaluation, including definitions, relevance, method of measurement and tips for visualization of the niche. A niche was defined as an indentation at the site of a Cesarean section with a depth of at least 2 mm. Basic measurements, including niche length and depth, residual and adjacent myometrial thickness in the sagittal plane, and niche width in the transverse plane, were considered to be essential. If present, branches should be reported and additional measurements should be made. The use of gel or saline contrast sonography was preferred over standard transvaginal sonography but was not considered mandatory if intrauterine fluid was present. Variation in pressure generated by the transvaginal probe can facilitate imaging, and Doppler imaging can be used to differentiate between a niche and other uterine abnormalities, but neither was considered mandatory. CONCLUSION Consensus between niche experts was achieved regarding ultrasonographic niche evaluation. © 2018 The Authors.

Abstract
OBJECTIVE To evaluate intra- and inter-observer agreement in measurements of the cesarean scar niche and the residual myometrial thickness (RMT) using 3-dimensional (3D) transvaginal ultrasonography. STUDY DESIGN Fifty-eight uterine 3D volumes from women with deep cesarean scar niches were evaluated. 3D volumes were obtained six to fifteen months after a primary cesarean section. Evaluation of the 3D volume was performed in a standardized multiplanar view. Two observers independently obtained RMT, cesarean scar niche depth (D), length (L), width (W), and myometrium adjacent to the scar (M). Differences within and between observers were expressed in mm and were evaluated according to the Bland-Altman method including the calculation of limits of agreement (LOAs). RESULTS The intra-observer LOAs in mm were as follows: RMT: -3.7 to 4.0; D: -2.2 to 2.6; L: -3.6 to 4.2; W: -4.0 to 3.7; and M: -3.4 to 4.5. The inter-observer LOAs in mm were as follows: RMT: -3.2 to 4.1; D: -3.3 to 2.2; L: -3.4 to 4.2; W: -3.2 to 4.1; and M: -4.1 to 3.2. CONCLUSIONS In non-pregnant women, we found rather wide limits of agreement measuring the cesarean section scar niche and myometrium using 3D volumes. Whether 3D transvaginal ultrasonography provides clinical advantages compared to 2D TVU needs clarification.

Abstract
The MUSA (Morphological Uterus Sonographic Assessment) statement is a consensus statement on terms, definitions and measurements that may be used to describe and report the sonographic features of the myometrium using gray-scale sonography, color/power Doppler and three-dimensional ultrasound imaging. The terms and definitions described may form the basis for prospective studies to predict the risk of different myometrial pathologies, based on their ultrasound appearance, and thus should be relevant for the clinician in daily practice and for clinical research. The sonographic features and use of terminology for describing the two most common myometrial lesions (fibroids and adenomyosis) and uterine smooth muscle tumors are presented.

Abstract
OBJECTIVES To evaluate the diagnostic efficiency of two-dimensional (2D) and three-dimensional (3D) transvaginal ultrasonography, power Doppler angiography (PDA) and gel infusion sonography (GIS) at offline analysis for recognition of malignant endometrium compared with real-time evaluation during scanning, and to determine optimal image parameters at 3D analysis. METHODS One hundred and sixty-nine consecutive women with postmenopausal bleeding and endometrial thickness ≥ 5 mm underwent systematic evaluation of endometrial pattern on 2D imaging, and 2D videoclips and 3D volumes were later analyzed offline. Histopathological findings at hysteroscopy or hysterectomy were used as the reference standard. The efficiency of the different techniques for diagnosis of malignancy was calculated and compared. 3D image parameters, endometrial volume and 3D vascular indices were assessed. Optimal 3D image parameters were transformed by logistic regression into a risk of endometrial cancer (REC) score, including scores for body mass index, endometrial thickness and endometrial morphology at gray-scale and PDA and GIS. RESULTS Offline 2D and 3D analysis were equivalent, but had lower diagnostic performance compared with real-time evaluation during scanning. Their diagnostic performance was not markedly improved by the addition of PDA or GIS, but their efficiency was comparable with that of real-time 2D-GIS in offline examinations of good image quality. On logistic regression, the 3D parameters from the REC-score system had the highest diagnostic efficiency. The area under the curve of the REC-score system at 3D-GIS (0.89) was not improved by inclusion of vascular indices or endometrial volume calculations. CONCLUSION Real-time evaluation during scanning is most efficient, but offline 2D and 3D analysis is useful for prediction of endometrial cancer when good image quality can be obtained. The diagnostic efficiency at 3D analysis may be improved by use of REC-scoring systems, without the need for calculation of vascular indices or endometrial volume. The optimal imaging modality appears to be real-time 2D-GIS.

Abstract
OBJECTIVES To assess interobserver reproducibility among ultrasound experts and gynecologists in the prediction by transvaginal ultrasound of deep myometrial and cervical stromal invasion in women with endometrial cancer. METHODS Sonographic videoclips of the uterine corpus and cervix of 53 women with endometrial cancer, examined preoperatively by the same ultrasound expert, were integrated into a digitalized survey. Nine ultrasound experts and nine gynecologists evaluated presence or absence of deep myometrial and cervical stromal invasion. Histopathology from hysterectomy specimens was used as the gold standard. RESULTS Compared with gynecologists, ultrasound experts showed higher sensitivity, specificity and agreement with histopathology in the assessment of cervical stromal invasion (42% (95% CI, 31-53%) vs 57% (95% CI, 45-68%), P < 0.01; 83% (95% CI, 78-86%) vs 87% (95% CI, 83-90%), P = 0.02; and kappa, 0.45 (95% CI, 0.40-0.49) vs 0.58 (95% CI, 0.53-0.62), P < 0.001, respectively) but not of deep myometrial invasion (73% (95% CI, 66-79%) vs 73% (95% CI, 66-79%), P = 1.0; 70% (95% CI, 65-75%) vs 69% (95% CI, 63-74%), P = 0.68; and kappa, 0.48 (95% CI, 0.44-0.53) vs 0.52 (95% CI, 0.48-0.57), P = 0.11, respectively). Though interobserver reproducibility (in the context of test proportions 'good' and 'very good', according to kappa) regarding deep myometrial invasion did not differ between the groups (experts, 34% vs gynecologists, 22%, P = 0.13), ultrasound experts assessed cervical stromal invasion with significantly greater interobserver reproducibility than did gynecologists (53% vs 14%, P < 0.001). CONCLUSION Preoperative ultrasound assessment of deep myometrial and cervical stromal invasion in endometrial cancer is best performed by ultrasound experts, as, compared with gynecologists, they showed a greater degree of agreement with histopathology and greater interobserver reproducibility in the assessment of cervical stromal invasion.

An ultrasound algorithm for identification of endometrial cancer. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2014; 43:557-568. [PMID: 24009152 DOI: 10.1002/uog.13205] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2013] [Revised: 08/27/2013] [Accepted: 09/02/2013] [Indexed: 06/02/2023]
Abstract
OBJECTIVE To propose a scoring system to predict endometrial cancer using different ultrasound image characteristics at gray-scale, with and without enhancement by gel infusion, and Doppler transvaginal sonography (TVS) and to evaluate intra- and interobserver variability in assessment of these characteristics. METHOD Unenhanced TVS, Doppler examinations and gel infusion sonography (GIS) were performed prospectively in 174 consecutive postmenopausal women with endometrial thickness ≥ 5 mm. The reference standard in all women was hysteroscopy or hysterectomy with pathological evaluation of the malignancy. The presence of various ultrasound pattern characteristics indicative of endometrial malignancy and intra- and interobserver variability in their assessment were evaluated. Multivariate logistic regression was used to correlate image and clinical parameters to presence of endometrial cancer. RESULTS A simple Doppler flow score (which considered only presence of vascularity and not presence of single/double dominant vessel, multiple vessels, large vessels, color splash or densely packed vessels) had an area under the receiver-operating characteristics curve (AUC) of 0.83 in the prediction of endometrial cancer. Models including endometrial thickness, Doppler score and interrupted endomyometrial junction on unenhanced TVS predicted endometrial cancer with an AUC of 0.95 (95% CI, 0.92-0.99) and, with addition of irregular surface on GIS, the AUC was 0.97 (95% CI, 0.94-0.99). A risk of endometrial cancer (REC) scoring system based on body mass index, Doppler score, endometrial thickness and interrupted endomyometrial junction on unenhanced TVS and irregular surface at GIS performed very well at identifying endometrial cancer; at a REC-score of ≥ 4 the sensitivity for detection of endometrial cancer was 91% and specificity was 94%. Observers agreed in 82.3% of cases (kappa, 0.63 (0.48-0.78)) when subjective parameters were analyzed in stored videoclips. CONCLUSION Our observer-dependent proposed scoring system seems to perform well in the prediction of endometrial cancer and should be tested in future studies.

Abstract
OBJECTIVES To compare residual myometrial thickness (RMT) and size of the Cesarean scar defect after single- and double-layer uterotomy closure following first elective Cesarean section. METHODS A retrospective cohort study was conducted in 149 women at least 6 months after an uncomplicated, elective Cesarean delivery. Two-dimensional transvaginal ultrasonographic measures of RMT, scar defect depth, width and length and myometrial thickness adjacent to the scar were compared in 68 women with single-layer and 81 women with double-layer closure delivered before and after, respectively, a change in the surgical procedure. Outcomes between the two groups were compared. RESULTS Median RMT was 5.8 (interquartile range (IQR), 4.1-7.8) mm in women with double-layer closure vs 4.6 (IQR, 3.4-6.5) mm in those with single-layer closure (P = 0.04). Scar defect length was greater in women with single-layer closure (median, 6.8 (IQR, 4.4-8.5) mm) than in those with double-layer closure (median, 5.6 (IQR, 3.9-6.8) mm) (P = 0.01). Measurements of defect depth and width, and the proportion of scars with RMT < 2.3 mm were similar in the two groups. CONCLUSIONS RMT was greater and defect length, but not defect depth and width, was smaller following double-layer compared with single-layer closure, which may indicate some limited benefit of double-layer closure following first elective Cesarean section.

Abstract
OBJECTIVE To evaluate the feasibility of ultrasound-guided radiofrequency ablation (USgRFA) for the treatment of women with symptomatic uterine fibroids in relation to volume of fibroid. METHODS Forty-three women with symptomatic fibroids underwent USgRFA for treatment of uterine fibroids. Improvements in fibroid symptoms and quality of life were measured by the Uterine Fibroid Symptom and Quality of Life questionnaire scores at baseline and 3, 6 and 9 months after the intervention, and analyzed in relation to baseline fibroid volume. Volume reduction of fibroids was measured and the frequency of adverse events and re-interventions was recorded. RESULTS Following USgRFA, mean Symptom Severity Scores (SSS) decreased from 60.7 ± 17.8 to 31.2 ± 19.5, corresponding to an improvement of 48.6%. The total Health-Related Quality of Life (HRQOL) score improved by 46.4% from 55.6 ± 20.9 to 81.4 ± 16.6. There was no correlation between fibroid volume at baseline and improvement in SSS and HRQOL scores. Fibroid volume was reduced in all patients, by a mean of 69.7 ± 19.4%. Two (4.7%) patients underwent hysterectomy. No adverse events occurred. CONCLUSION USgRFA reduces fibroid symptom and size even in patients with larger fibroids. USgRFA is a promising new treatment for fibroids in gynecological settings and should be further investigated.

Abstract
OBJECTIVE To compare the diagnostic potential of magnetic resonance imaging (MRI) and transvaginal ultrasonography (TVS) in the diagnosis of adenomyosis. DESIGN Double blind set-up. SETTING University medical school. PATIENT(S) We studied 106 consecutive premenopausal women who underwent hysterectomy for benign reasons. INTERVENTION(S) Transvaginal ultrasonography and MRI were compared with histopathologic examination as the golden standard. MAIN OUTCOME MEASURE(S) Adenomyosis. RESULT(S) Twenty-two (21%) patients had adenomyosis. The sensitivity and specificity were as follows: sensitivity: MRI 0.70 (0.46-0.87) and TVS 0.68 (0.44-0.86) (P=.66); specificity: MRI 0.86 (0.76-0.93) and TVS 0.65 (0.50-0.77) (P=.03). The combination of MRI and TVS was most sensitive (0.89 [0.64-0.98]), but produced the lowest specificity (0.60 [0.44-0.73]). Adenomyosis was not detected by either MRI or TVS at uterine volumes >400 mL. Exclusion of uteri >400 mL from the analysis improved the diagnostic precision of MRI, but not that of TVS. The diagnostic accuracy at MRI was improved by calculating the maximum difference between the thinnest and thickest junctional zone (JZdif) (i.e., > or =5-7 mm). CONCLUSION(S) Magnetic resonance imaging was superior to TVS for the diagnosis of adenomyosis. Magnetic resonance imaging had a higher specificity than TVS, but their sensitivities were in line. The diagnostic accuracy of MRI, as that of TVS, was at an intermediate level, but the diagnostic accuracy of the former improved by exclusion of uteri >400 mL. The combination of MRI and TVS produced the highest level of accuracy for exclusion of adenomyosis, but the low specificity may necessitate further investigation of positive findings. Measurement of the difference in junctional zone thickness may optimize the diagnosis of adenomyosis at MRI.

Abstract
OBJECTIVE To evaluate and compare the diagnostic accuracy of magnetic resonance imaging (MRI), transvaginal ultrasonography (TVS), hysterosonographic examination (HSE), and hysteroscopy in the evaluation of the uterine cavity. DESIGN Independent double-blind study. SETTING University medical hospital. PATIENT(S) One hundred six consecutive premenopausal women who underwent hysterectomy for benign diseases. INTERVENTION(S) Results of MRI, TVS, HSE, and hysteroscopy were compared with the results of histopathologic examination at hysterectomy (the gold standard). RESULT(S) The overall sensitivity was MRI 0.76, TVS 0.69, HSE 0.83, and hysteroscopy 0.84. The specificity was MRI 0.92, TVS 0.83, HSE 0.90, and hysteroscopy 0.88 (MRI, HSE, hysteroscopy vs. TVS <0.05). Polyps were missed in 9 of 12 cases at MRI, 7 at TVS, 4 at HSE, and 2 at hysteroscopy (MRI vs. hysteroscopy, and TVS vs. hysteroscopy <0.05). The sensitivity for identification of submucous myomas was MRI 1.0, TVS 0.83, HSE 0.90, and hysteroscopy 0.82; the specificity was MRI 0.91, TVS 0.90, HSE 0.89, and hysteroscopy 0.87 (MRI vs. TVS, and MRI vs. hysteroscopy). Magnetic resonance imaging was significantly more precise than TVS, HSE, and hysteroscopy in determining submucous myoma in-growth (2-way ANOVA <0.05). CONCLUSION(S) For exclusion of abnormalities in the uterine cavity, MRI, HSE, and hysteroscopy were equally effective and slightly superior to TVS. Magnetic resonance imaging and TVS missed endometrial abnormalities such as polyps, but MRI and HSE were most accurate for the evaluation of submucous myomas, and MRI was superior in evaluation of exact submucous myoma in-growth.

Abstract
OBJECTIVES To evaluate whether saline contrast sonohysterography (SCSH) adds additional information to that obtained by transvaginal sonography (TVS) for predicting endometrial abnormality in premenopausal patients with abnormal uterine bleeding. PATIENTS AND METHODS This was a two-center prospective study at a university clinic and a central hospital in Denmark. The uterine cavity was evaluated with TVS and SCSH in 470 premenopausal patients with abnormal uterine bleeding. One hundred and eighty-nine of the patients had operative hysteroscopy or hysterectomy within 4 months which provided a detailed description of the uterine cavity and was used as the true value for exclusion of polyps and submucous myomas. RESULTS Based on normal endometrial morphology alone, the results for detection of an abnormal uterine cavity were as follows: sensitivities of TVS 0.92, SCSH 0.99; specificities of TVS 0.62, SCSH 0.72; positive predictive values of TVS 0.80, SCSH 0.85; negative predictive values of TVS 0.82, SCSH 0.98. Transvaginal sonography combined with SCSH was superior to TVS for detection of intracavitary abnormalities (McNemar test, P = 0.008). The post-test probability of there being an abnormal cavity after normal findings on TVS alone was 0.18 (0.10-0.32) and after TVS and SCSH it was 0.02 (0.01-0.11). When normal endometrial morphology was combined with an endometrial thickness of < 12 mm for evaluation of all abnormalities including hyperplasia, the diagnostic potential of TVS or SCSH was almost unchanged except for specificities, which were markedly lower (TVS 0.54; SCSH 0.57). In all the patients referred, TVS had a negative predictive value of 0.94 for identification of polyps and myomas when findings at subsequent SCSH were accepted as the true value. Transvaginal sonography reduced the pretest probability of polyps or submucous myomas from 0.35 to a post-test probability of 0.06, but missed 21% of the polyps. CONCLUSIONS Sonohysterography was a sensitive tool and was superior to TVS used alone for evaluation of the uterine cavity in patients who underwent operative surgery for abnormal uterine bleeding. All abnormalities except one were found at SCSH, while TVS alone missed polyps and had almost one in four equivocal findings. The use of TVS, without saline contrast, left one in five of the polyps undiagnosed in referred patients with abnormal bleeding.

Abstract
BACKGROUND To combine findings of normal mid-line echoes from TVS (trans-vaginal sonography) with cut-off levels for endometrial thickness, in order to examine the associated risk of abnormalities in the uterine cavity. DESIGN AND SETTING Two center prospective study at a university clinic and a central hospital in Denmark. PARTICIPANTS Three hundred and fifty-five pre-menopausal patients with abnormal uterine bleeding, and indications for endometrial sampling or surgery. INTERVENTIONS The thickness of the endometrium was measured, and the mid-line echoes were evaluated using TVS. The findings from the endometrial sampling, combined with the evaluation of the uterine cavity using operative hysteroscopy (115), hysterectomy (74) or HSE (hysterosonographic examination) (166), were used as the true values. RESULTS The mean (+/-s.d.) endometrial thickness was significantly different in patients with hyperplasia 11.5 mm (+/-5.0), polyps 11.8 mm (+/-5.1), sub-mucous myomas 7.1 mm (+/-3.4) and in patients without these abnormalities 8.37 (+/-3.9) (p<0.001). Hyperplasia and/or polyps were present in 20% of all patients, and in 8% of 143 patients with an endometrial thickness of < or =7 mm. This proportion did not decrease with lower cut-off levels for endometrial thickness. Receiver operating characteristic (ROC) curves were not optimal for excluding hyperplasia or polyps by endometrial thickness. In 173 cases with a distinct, regular midline echo without echo-dense foci in TVS the proportion of patients with abnormalities was 16% (11-23). This proportion did not decrease with cut-off levels for endometrial thickness. CONCLUSIONS Using TVS, low levels of endometrial thickness reduced the possibility of abnormalities such as polyps and hyperplasia, but did not exclude them. Low cut-off levels for endometrial thickness did not increase the diagnostic performance in cases with normal sonograms.

Abstract
BACKGROUND The purpose of the present study was to evaluate a one-stop outpatient bleeding disorder clinic in a Scandinavian population. METHODS One hundred and fourteen women under the age of 60 years referred to the clinic for bleeding disorders. The consultation included pelvic ultrasound, hysterosonography and, when indicated, endometrial sampling. RESULTS In 93% of the patients a sufficient diagnosis of the uterine cavity was attained at a one-stop visit. Eighty-six percent of the patients were investigated according to the one-stop program, and in 73% of the patients a treatment plan could be formulated during the consultation. Twenty-one percent had selective resection of intracavitary abnormalities. In 3% no intracavitary abnormality was found at hysteroscopy, even though hysterosonography had indicated this. CONCLUSIONS Most patients under the age of 60 with bleeding disorders can be investigated by a one-stop out-patient procedure with the use of hysterosonography and endometrial sampling. Diagnostic or operative hysteroscopy was needed in cases of insufficient hysterosonography and suspicion of intracavitary abnormalities. This procedure can assist in determining the therapeutic approach and can often lessen the extent of surgical intervention or obviate it altogether.

Abstract
BACKGROUND The validity of cytobrush and endocervical curettage combined with colposcopically directed biopsies in the diagnosis of cervical dysplasia and malignancy has not been evaluated in randomized trials. We aimed to elucidate the diagnostic validity of the two methods. METHODS A prospective, randomized study of 180 consecutive patients. All patients were examined without anesthesia by colposcopically directed biopsies of the ectocervix and randomly assigned to either cytobrush or endocervical curettage. Patients with < or = CIN 1 were investigated with the alternative method three months later. Patients with > or = CIN 2 had a cone biopsy. RESULTS One hundred and thirty-one patients were evaluable. The sensitivity of cytobrush and endocervical curettage combined with colposcopically directed biopsies of the ectocervix was 96% and 84% (p = 0.08), respectively. The specificities of the two investigations were 95% and 88%, respectively (p = 0.78). All cytobrush specimens were evaluable but because of a low recovery of endocervical material a diagnosis could not be made in 12% of the patients examined by endocervical curettage. CONCLUSION The sensitivity of the combined use of cytobrush and biopsies of the ectocervix was equal to or higher than the sensitivity of endocervical curettage and ectocervical biopsies. The specificities of the two investigations were much alike. All cytobrush specimens were evaluable but a diagnosis could not be performed in 12% of the endocervical curettage specimens because of too little endocervical material. Furthermore, cytobrush is less inconvenient to the patient. Therefore, in the follow-up of patients with cervical dysplasia endocervical curettage may be replaced with cytobrush.

Abstract
Lupus anticoagulant (LA) and anticardiolipin antibodies (ACA) have been reported to be associated with fetal loss. OBJECTIVE. Our aim was to estimate the incidence of LA and to examine the correlation between LA and ACA in pregnant women. To investigate the clinical significance of LA and ACA in an obstetric population. STUDY DESIGN. A prospective, cross sectional study of 2856 consecutive women admitted to a department of obstetrics and gynecology for delivery or due to pregnancy complications during an 11 month period. METHODS. Activated partial thromboplastin time (APTT) was determined in all patients. LA and ACA were determined if APTT > or = 35 sec. For reference ACA was determined in a group of randomly selected patients with APTT < 35 sec. The results were analyzed in relation to the obstetrical records. RESULTS. Overall incidence of APTT > or = 35 sec.: 7.0%, significantly more frequent in patients with early spontaneous abortion (18.6%) and intrauterine growth retardation (17.5%). Incidence of LA 0.07%. The patients had undetectable ACA and no clinical condition related to LA. Incidence of ACA class IgM (IgM-ACA) in patients with APTT > or = 35: 20.4%, significantly higher than in the reference group (9.6%). Uncomplicated pregnancy in 84% of patients with IgM-ACA. No cases of ACA class IgG (IgG-ACA) in patients with APTT > or = 35 but two cases in the reference group (one normal pregnancy, one spontaneous abortion). CONCLUSION. LA is a rare manifestation with uncertain significance in otherwise healthy pregnant women. IgM-ACA in low titer occurs relatively frequently during normal pregnancy.

Abstract
Sixty-five patients with chronic bronchitis were studied at five different centres in a double-blind, randomized trial. Two parallel groups were treated with either N-acetylcysteine or placebo by metered dose inhalers for 16 weeks. Following a 1-week run-in period, each patient recorded subjective impressions of the drug action on their bronchitic symptoms in a diary once a week. In addition, exacerbations were registered. Lung function testing and adverse effects were evaluated by four visits to the chest clinics during the 16 weeks. We could not demonstrate that N-acetylcysteine by metered dose inhalers had any significant effect on patients' feeling of well-being, sensation of dyspnoea, intensity of coughing, mucus production, or expectoration or lung function. Its effect in reducing exacerbations could not be estimated because of a very low number of exacerbations reported. N-acetylcysteine inhalation was safe when used over a 16-week period.

Abstract
Allergy to storage mites has been shown among farmers and grain elevator workers. This study aimed to examine whether bakers also are sensitized to storage mites. Twenty-three bakers or other employees in bakeries suffering from nasal or pulmonary symptoms were compared with 17 control persons with no relation to bakery work or agriculture. All participants underwent skin prick test with a standard panel of allergens, four types of flour and the storage mites Acarus siro, Lepidoglyphus destructor and Tyrophagus putrescentiae, RAST to storage mites and flour, and measurement of total IgE. We found no difference between the baker group and the control group in prevalence and strength of positive skin prick test or RAST to any of the three storage mite species. In the baker group positive RAST to flour was related to positive RAST to A. siro and L. destructor, but not T. putrescentiae. Almost all bakers sensitized to flour were also sensitized to storage mites (6 of 7). We suggest that if a baker become sensitized to flour he will be more prone to develop specific IgE towards storage mites too.

Abstract
In the Central Hospital in Randers, 233 fathers of first infants replied to a questionnaire which illustrated their attitudes to the preparatory courses about delivery, experience of delivery and attitudes to paternity leave. 65% of the fathers participated in the course and 74% stated that they considered that this had been profitable. Where 77% of the men were concerned, these considered that participation in delivery had been a positive experience. 73% of the men had planned paternity leave around the time of delivery, which emphasizes the need for this arrangement.

Abstract
Isolated torsion of the fallopian tube is a rare disease of unknown etiology. Pathological conditions often pre-dispose to torsion. The correct diagnosis is usually not established until the operation and it is almost always necessary to remove the tube. Awareness of this condition and early laparoscopy in case of unexplained acute low abdominal pain may result in early diagnosis and possible preservation of the affected tube.

Abstract
A hydatidiform mole associated with a fetus proved to be the result of twin gestation. On microscopic examination of the placenta the case was classified as a partial hydatidiform mole. Chromosomal markers were, however, consistent with a normal conception and a mole of diploid androgenetic origin. Chromosome analysis of a morphologic complete molar specimen yielded two cell lines, one consistent with a normal conception and one with diploid androgenesis. Twinning in molar specimens must therefore be considered, regardless of macroscopic appearance. The prenatal diagnosis of a coexisting fetus and molar placenta poses a real clinical problem; analyses must distinguish between a partial mole plus a triploid fetus and a normal fetus occurring with a partial or a complete mole. The distinction is important for decisions made during pregnancy and may be of prognostic significance after termination. The usefulness of chromosome marker analysis in distinguishing between the various origins is pointed out, and it is suggested that twin pregnancy with hydatidiform mole is more frequent than its description in the literature would suggest.
