Artificial intelligence model for enhancing the accuracy of transvaginal ultrasound in detecting endometrial cancer and endometrial atypical hyperplasia.

OBJECTIVES: Transvaginal ultrasound is typically the initial diagnostic approach in patients with postmenopausal bleeding for detecting endometrial atypical hyperplasia/cancer. Although transvaginal ultrasound demonstrates notable sensitivity, its specificity remains limited. The objective of this study was to enhance the diagnostic accuracy of transvaginal ultrasound through the integration of artificial intelligence. By using transvaginal ultrasound images, we aimed to develop an artificial intelligence based automated segmentation model and an artificial intelligence based classifier model. METHODS: Patients with postmenopausal bleeding undergoing transvaginal ultrasound and endometrial sampling at Mayo Clinic between 2016 and 2021 were retrospectively included. Manual segmentation of images was performed by four physicians (readers). Patients were classified into cohort A (atypical hyperplasia/cancer) and cohort B (benign) based on the pathologic report of endometrial sampling. A fully automated segmentation model was developed, and the performance of the model in correctly identifying the endometrium was compared with physician made segmentation using similarity metrics. To develop the classifier model, radiomic features were calculated from the manually segmented regions-of-interest. These features were used to train a wide range of machine learning based classifiers. The top performing machine learning classifier was evaluated using a threefold approach, and diagnostic accuracy was assessed through the F1 score and area under the receiver operating characteristic curve (AUC-ROC). RESULTS: 302 patients were included. Automated segmentation-reader agreement was 0.79±0.21 using the Dice coefficient. For the classification task, 92 radiomic features related to pixel texture/shape/intensity were found to be significantly different between cohort A and B. The threefold evaluation of the top performing classifier model showed an AUC-ROC of 0.90 (range 0.88-0.92) on the validation set and 0.88 (range 0.86-0.91) on the hold-out test set. Sensitivity and specificity were 0.87 (range 0.77-0.94) and 0.86 (range 0.81-0.94), respectively. CONCLUSIONS: We trained an artificial intelligence based algorithm to differentiate endometrial atypical hyperplasia/cancer from benign conditions on transvaginal ultrasound images in a population of patients with postmenopausal bleeding.

What are essential laparoscopic skills these days? Results of the SAGES Fundamentals of Laparoscopic Surgery (FLS) Committee technical skills survey.

INTRODUCTION: The Fundamentals of Laparoscopic Surgery (FLS) program tests basic knowledge and skills required to perform laparoscopic surgery. Educational experiences in laparoscopic training and development of associated competencies have evolved since FLS inception, making it important to review the definition of fundamental laparoscopic skills. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) assigned an FLS Technical Skills Working Group to characterize technical skills used in basic laparoscopic surgery in current practice contexts and their possible application to future FLS tests. METHODS: A group of subject matter experts defined an inventory of 65 laparoscopic skills using a Nominal Group Technique. From these, a survey was developed rating these items for importance, frequency of use, and priority for testing for FLS certification. This survey was distributed to SAGES members, recent recipients of FLS certification, and members of the Association of Program Directors in Surgery (APDS). Results were collected using a secure web-based survey platform. RESULTS: Complete data were available for 1742 surveys. Of these, 1143 comprised results for post-residency participants who performed advanced procedures. Seventeen competencies were identified for FLS testing prioritization by determining the proportion of respondents who identified them of highest priority, at median (50th percentile) of the maximum survey scale rating. These included basic peritoneal access, laparoscope and instrument use, tissue manipulation, and specific problem management skills. Sixteen could be used to show appropriateness of the domain construct by confirmatory factor analysis. Of these 8 could be characterized as manipulative tasks. Of these 5 mapped to current FLS tasks. CONCLUSIONS: This survey-identified competencies, some of which are currently assessed in FLS, with a high level of priority for testing. Further work is needed to determine if this should prompt consideration of changes or additions to the FLS technical skills test component.

Improving patient access through office hysteroscopy clinic redesign.

BACKGROUND AND OBJECTIVE: Patients with abnormal uterine bleeding (AUB) often require hysteroscopy as part of the diagnostic workup. The purpose of this study was to improve efficiency by shortening the time to patient appointment for office hysteroscopy. INTERVENTIONS: Preintervention, nurse practitioners (NPs) and gynecologists saw patients with abnormal uterine bleeding (AUB) separately. This created inefficiency for the patients, frequently requiring second visits for hysteroscopy. A new hysteroscopy clinic was designed to increase practice efficiency. A collaborative team model was created including consecutive visits with NPs and gynecologists. Each patient with AUB was first evaluated by an NP, followed immediately by a shorter visit with a gynecologist for office hysteroscopy as indicated. NPs managed other diagnostic evaluation and bleeding treatment if hysteroscopy was not warranted. Collaborative clinic staffing consisted of two NPs seeing patients with AUB paired with one gynecologist for procedural support. MEASUREMENTS AND RESULTS: Electronic records of 393 patients scheduled for AUB visits from January to June 2015 were evaluated for preintervention data. Postintervention, 647 patient records were reviewed from January to June of 2016. During the preintervention period, 30% of patients had a hysteroscopy appointment scheduled within 0-13 days from the initial visit for AUB. Postintervention, the wait time for appointments decreased, with 63% of patients scheduled within 0-13 days. Clinic redesign also resulted in an increase of 57.5% in appointment slots. No-show rates and appointment fill rates were not adversely affected. CONCLUSIONS: A collaborative team-based care model using NPs and gynecologists improved efficiency and access to office hysteroscopy services.

Medical therapy versus radiofrequency endometrial ablation in the initial treatment of heavy menstrual bleeding (iTOM Trial): A clinical and economic analysis.

BACKGROUND: Radiofrequency endometrial ablation (REA) is currently a second line treatment in women with heavy menstrual bleeding (MHB) if medical therapy (MTP) is contraindicated or unsatisfactory. Our objective is to compare the effectiveness and cost burden of MTP and REA in the initial treatment of HMB. METHODS: We performed a randomized trial at Mayo Clinic Rochester, Minnesota. The planned sample size was 60 patients per arm. A total of 67 women with HMB were randomly allocated to receive oral contraceptive pills (Nordette ®) or Naproxen (Naprosyn®) (n = 33) or REA (n = 34). Primary 12-month outcome measures included menstrual blood loss using pictorial blood loss assessment chart (PBLAC), patients' satisfaction, and Menorrhagia Multi-Attribute Scale (MMAS). Secondary outcomes were total costs including direct medical and indirect costs associated with healthcare use, patient out-of-pocket costs, and lost work days and activity limitations over 12 months. RESULTS: Compared to MTP arm, women who received REA had a significantly lower PBLAC score (median [Interquartile range, IQR]: 0 [0-4] vs. 15 [0-131], p = 0.003), higher satisfaction rates (96.8%vs.63.2%, p = 0.003) and higher MMAS (median [IQR]: 100 [100-100] vs. 100 [87-100], p = 0.12) at 12 months. Direct medical costs were higher for REA ($5,331vs.$2,901, 95% confidence interval (CI) of mean difference:$727,$4,852), however, when indirect costs are included, the difference did not reach statistical significance ($5,469 vs. $3,869, 95% CI of mean difference:-$339, $4,089). CONCLUSION: For women with heavy menstrual bleeding, initial radiofrequency endometrial ablation compared to medical therapy offered superior reduction in menstrual blood loss and improvement in quality of life without significant differences in total costs of care.

Clinical Manifestations and Outcomes in Surgically Managed Gartner Duct Cysts.

STUDY OBJECTIVE: Gartner duct cysts (GDCs) are rare embryological remnants of the mesonephric duct with the majority of cases discovered incidentally in asymptomatic patients. The largest prior published series evaluating the surgical management of GDCs included 4 patients. The present study aimed to determine the manifestations and outcomes of surgically managed patients with GDCs with important implications for surveillance, monitoring, and management. DESIGN: A retrospective chart review (Canadian Task Force classification III). SETTING: A tertiary care center. PATIENTS: All women diagnosed with GDCs from January 1994 to April 2014 at our institution were identified. Patients were included if they underwent surgical management and had GDCs confirmed by pathology. One hundred twenty-four charts were manually reviewed, and 29 patients were included in the analysis. INTERVENTIONS: All patients underwent surgical management, which included vaginal excision or marsupialization. MEASUREMENTS AND MAIN RESULTS: A total of 29 patients met the inclusion criteria for this study. The median age of the patients included in the analysis was 36 years old. Eleven patients were asymptomatic at the time of diagnosis (37.9%). The reason for surgical intervention was not available in 9 of these patients. Surgical intervention was performed in 2 of the 11 asymptomatic patients because of an increasing size of the lesion during observation. Presenting symptoms included dyspareunia or pain with tampon placement (37.9%), pelvic pain or pressure (24.1%), pelvic mass or bulge (17.2%), and urinary incontinence (6.9%). Preoperative imaging studies were obtained in 62% of patients; ultrasound was used in 44.4%, computed tomographic scanning in 22.2%, magnetic resonance imaging in 16.7%, and multiple modalities in 16.7%. Approximately 10% were found to have other genitourinary anomalies, including a bladder cyst, urethral diverticulum, and a solitary right kidney with uterine didelphis and septate vagina. The average cyst size was 3.5 cm (±1.8 cm). Surgical excision of GDCs was performed in all except for 3 cases of marsupialization. No intraoperative complications occurred. The median follow-up was 82 months (range, 0-246 months). One patient had possible recurrence with dyspareunia and protruding tissue diagnosed 14 months postoperatively. There were no other postoperative complications in the follow-up period. CONCLUSION: GDCs are rare pelvic masses that are often asymptomatic but may present with dyspareunia, pelvic pain or pressure, pelvic mass or bulge, or urinary symptoms. Excision or marsupialization is successful in the majority of cases without significant morbidity.

Hysteroscopic Morcellation Versus Resection for the Treatment of Uterine Cavitary Lesions: A Systematic Review and Meta-analysis.

This systematic review and meta-analysis compares hysteroscopic morcellation with electrosurgical resection to treat uterine cavitary lesions. A search of Ovid MEDLINE, Ovid Embase, Scopus, and Web of Science was conducted through August 18, 2015, for randomized controlled trials (RCTs) and prospective and retrospective studies, regardless of surgical indication and study language or sample size. Seven studies were eventually included (4 RCTs and 3 retrospective observational studies), enrolling 650 women. The meta-analysis showed that the total procedure time was significantly shorter for morcellation than for resection (weighted mean difference = 9.36 minutes; 95% confidence interval [CI], -15.08 to -3.64). When reviewing RCTs only, intrauterine morcellation was associated with a smaller fluid deficit and lower odds of incomplete lesion removal. This difference was not statistically significant in observational studies. There was no significant difference in the odds of surgical complications (odds ratio = 0.72; 95% CI, 0.20-2.57) or the number of insertions (weighted mean difference = -3.04; 95% CI, -7.86-1.78). In conclusion, compared with hysteroscopic resection, hysteroscopic morcellation is associated with a shorter operative time and possibly lower odds of incomplete lesion removal. The certainty in evidence was limited by heterogeneity and the small sample size.

Impact of Simple Ovarian Cysts on the Interpretation of Endometrial Thickness in Women with Postmenopausal Bleeding.

BACKGROUND: There is evidence that premenopausal hormones may persist for variable time after menopause. Histological specimens from postmenopausal women support the presence of follicular growth at that age. Residual ovarian function may explain postmenopausal bleeding (PMB), which is not associated with endometrial pathology. Our objective was to evaluate the effect of sonographic diagnosis of simple ovarian cysts on the association between thickened endometrium and endometrial pathology in women with PMB. MATERIALS AND METHODS: Data were retrospectively collected from medical records of women who underwent office hysteroscopy for PMB between January 2007 and October 2011. Women with sonographic reports within 3 months of presentation were included. Endometrial thickness and the presence of a simple ovarian cyst (≤5 cm) were documented by reviewing sonographic reports. Diagnosis of endometrial pathology was abstracted according to pathology reports or hysteroscopic impression. Endometria with hyperplasia, cancer, or polyps were considered pathological. RESULTS: Of 836 women with PMB, 356 had recent transvaginal sonography and were included in the analysis. Pathological endometrium was documented in 129 (36.2%) women, including 29 (8.2%) with endometrial cancer. In women with PMB and no evidence of a simple ovarian cyst, endometrial thickness was an independent predictor of endometrial pathology and endometrial cancer with adjusted OR = 1.13 (95% CI = 1.07-1.19) and 1.16 (95% CI = 1.07-1.25), respectively. In the presence of simple ovarian cysts, the adjusted ORs for endometrial thickness as a predictor of endometrial pathology were 1.06 (95% CI = 0.90-1.25) and 0.84 (95% CI = 0.62-1.14), respectively. CONCLUSION: The presence of simple ovarian cysts (≤5 cm) tempers the value of endometrial thickness in predicting endometrial pathology in women with PMB.

Teaming Up for Women's Health: The 2015 American College of Obstetricians and Gynecologists Annual Clinical and Scientific Meeting.

63rd Annual Clinical and Scientific Meeting of the American College of Obstetricians and Gynecologists, 2-6 May, 2015, San Francisco, CA, USA. In response to major practice changes in obstetrics and gynecology (OB/GYN), the 2015 Annual Clinical and Scientific Meeting of the American College of Obstetricians and Gynecologists responded with modification of the program organization, methods of presenting the information (debates, hands on, flip classrooms) and increased emphasis on current clinical research. The Presidential Program covered broad themes of changes in healthcare technology, teamwork in OB/GYN practice and the importance of advocating for patients. Over 400 abstracts representing a broad range of clinical and basic science research were presented. Changes in the Annual Clinical and Scientific Meeting should allow the membership to be more prepared and pro-active as the practice of OB/GYN evolves.

Hysterosalpingography After Radiofrequency Endometrial Ablation and Hysteroscopic Sterilization as a Concomitant Procedure.

OBJECTIVE: To evaluate the accuracy of hysterosalpingography (HSG) in patients who underwent concomitant radiofrequency endometrial ablation and hysteroscopic sterilization. METHODS: This historical cohort study was conducted at a midwestern academic medical center. A total of 186 women (94 with combined procedure and 92 with sterilization alone) were identified as having undergone intervention between January 1, 2003, and June 30, 2011. Two reviewers blinded to the surgical procedure interpreted the standard clinically indicated HSGs in each group. RESULTS: The primary outcome assessed was the inability to rely on the microinserts for contraception based on HSG interpretation using manufacturers' guidelines (unsatisfactory HSG). Position of the devices and occlusion of tubes were assessed on all 3-month and, when available, all 6-month repeat HSGs. At the 3-month HSG, 5 of 76 (6.6%, 95% confidence interval [CI] 2.2-14.7%) in the sterilization-only group had unsatisfactory HSG compared with 13 of 71 (18.3%, 95% CI 10.1-29.3%) in the combined group (P=.03). After accounting for the seven patients who underwent repeat HSG at 6 months, 3 of 76 (3.95%, 95% CI 0.8-11.1%) in the sterilization-only group had unsatisfactory HSG compared with 13 of 71 (18.31%, 95% CI 10.1-29.3%) in the combined group (P=.005). CONCLUSION: After completing all clinically indicated HSGs, patients who undergo concomitant radiofrequency endometrial ablation and hysteroscopic sterilization have an approximate fivefold increase (odds ratio 5.45, 95% CI 1.48-20.0) in the rate of unsatisfactory HSG for purposes of documenting tubal occlusion. LEVEL OF EVIDENCE: II.

Perceived risk of cervical cancer among low-income women.

BACKGROUND: Risk perception is an important predictor of cancer prevention behaviors. We examined the perceived risk of cervical cancer among an ethnically diverse population of women of lower socioeconomic status. MATERIALS AND METHODS: Females attending a women's health clinic were recruited for a study addressing cervical cancer prevention. Survey questions evaluated lifetime perceived risk of cervical cancer (0%-100%), beliefs about the accuracy of the Pap test, and estimated incidence of abnormal Pap test results. Risk estimates for oneself were followed with an item seeking a brief, qualitative explanation of the risk estimate. RESULTS: Surveys were completed by 338 women. The mean (SD) age of respondents was 29.9 (8.6) years. Women self-identified as Hispanic/Latina (32%, n=107), White (34%, n=116), and African American (34%, n=115). Estimated perceived lifetime risk of getting cervical cancer ranged from 0% to 100% (59.2 [29.5]). Risk estimates were associated with perceived prevalence of abnormal results (r=0.24, p<.001) and perceptions regarding the accuracy of the Pap test (r=0.13, p<.05). On average, women estimated that nearly half of all women have ever had an abnormal result (49.2 [26.9]; n=335; range, 0%-100%), with African American women estimating a higher percentage compared to Hispanic/Latina and White women. Women who themselves experienced an abnormal Pap test result reported higher proportions of other women experiencing an abnormal result (t333=-3.67, p<.01). CONCLUSIONS: This study advances our understanding of misperception of risk and how women qualitatively view their risk of cervical cancer. The findings underscore areas for practitioners to enhance patient education efforts.

Asymptomatic thickened endometrium in postmenopausal women: malignancy risk.

STUDY OBJECTIVE: To assess the diagnostic findings and determine the frequency of malignancy in postmenopausal women evaluated by office hysteroscopy for a thickened endometrium without bleeding. DESIGN: Retrospective cohort (Canadian Task Force classification II-B). SETTING: Academic medical center in the Midwestern United States. PATIENTS: Over 3600 women underwent an office hysteroscopy between January 1, 2007, and October 20, 2011, for abnormal uterine bleeding or an abnormal ultrasound. Of these, 154 postmenopausal women had a thickened endometrium (>4 mm) and no bleeding. INTERVENTIONS: Flexible office hysteroscopy using a 3.1-mm scope with saline as the distending media was performed for clinical reasons, and results were captured within a research database. MEASUREMENTS AND MAIN RESULTS: For the 154 women, the range of endometrial measurements was 4.2 to 28 mm (mean = 10.0 mm). Hysteroscopy diagnoses included 93 patients with polyps, 19 with myomas or uterine synechiae, and 34 with benign-appearing endometrium. Nine hysteroscopies were inadequate because of poor visualization (n = 1), cervical stenosis (n = 6), or patient discomfort (n = 2). Endometrial biopsies (EMBs) were performed in 109 patients, and none were found to have cancer or an atypical endometrium. Six had simple hyperplasia without atypia, and their endometrial measurements were within the range of the patients in our study who had a benign endometrium (5-15 mm, mean = 10.3). Of the women with a polyp, 73 (78.4%) subsequently underwent polypectomy. On final pathology, 1 had cancer (endometrial measurement = 24 mm), and 1 had complex hyperplasia with atypia (endometrial measurement = 17 mm). EMBs performed in the office for these 2 patients showed an insufficient endometrium and inactive endometrium, respectively. CONCLUSION: Cancer and atypia can occur in asymptomatic women. Endometrial thickness was 17 mm or greater in 2 cases, and EMBs performed in the office were inconsistent with the final diagnosis. Hysteroscopy is important when ultrasound and EMB do not agree. Polypectomy may be indicated even in asymptomatic women, but further studies regarding an endometrial measurement threshold or polyp size are warranted.

Intervention to improve follow-up for abnormal Papanicolaou tests: a randomized clinical trial.

OBJECTIVE: To evaluate the effect of a theory-based, culturally targeted intervention on adherence to follow-up among low-income and minority women who experience an abnormal Pap test. METHOD: 5,049 women were enrolled and underwent Pap testing. Of these, 378 had an abnormal result and 341 (90%) were randomized to one of three groups to receive their results: Intervention (I): culturally targeted behavioral and normative beliefs + knowledge/skills + salience + environmental constraints/barriers counseling; Active Control (AC): nontargeted behavioral and normative beliefs + knowledge/skills + salience + environmental constraints/barriers counseling; or Standard Care Only (SCO). The primary outcome was attendance at the initial follow-up appointment. Secondary outcomes included delay in care, completion of care at 18 months, state anxiety (STAI Y-6), depressive symptoms (CES-D), and distress (CDDQ). Anxiety was assessed at enrollment, notification of results, and 7-14 days later with the CDDQ and CES-D. RESULTS: 299 women were included in intent-to-treat analyses. Adherence rates were 60% (I), 54% (AC), and 58% (SCO), p = .73. Completion rates were 39% (I) and 35% in the AC and SCO groups, p = .77. Delay in care (in days) was (M ± SD): 58 ± 75 (I), 69 ± 72 (AC), and 54 ± 75 (SCO), p = .75. Adherence was associated with higher anxiety at notification, p < .01 and delay < 90 days (vs. 90+) was associated with greater perceived personal responsibility, p < .05. Women not completing their care (vs. those who did) had higher CES-D scores at enrollment, p < .05. CONCLUSIONS: A theory-based, culturally targeted message was not more effective than a nontargeted message or standard care in improving behavior.

Direct aspiration endometrial biopsy via flexible hysteroscopy.

STUDY OBJECTIVE: To determine feasibility and efficacy of direct aspiration endometrial biopsy via the fluid channel of a flexible diagnostic hysteroscope. DESIGN: Retrospective review (Canadian Task Force classification II-3). SETTING: Abnormal uterine bleeding clinic in a tertiary care center. PATIENTS: All women who underwent direct aspiration endometrial biopsy from January 2007 through August 2011 via a flexible diagnostic hysteroscope because traditional office-based endometrial biopsy using a suction piston device was not technically possible. INTERVENTIONS: Diagnostic hysteroscopy followed by direct aspiration endometrial biopsy, accomplished by applying suction to the fluid channel of a 3.1-mm flexible diagnostic hysteroscope via a 10-mL syringe. The hysteroscope tip was agitated within the uterine cavity to obtain a tissue sample. MEASUREMENTS AND MAIN RESULTS: The median age of the 32 identified patients was 50 years; 18 women (56%) were nulliparous, and 10 (31%) were postmenopausal. Thirty-one patients underwent hysteroscopy/direct aspiration biopsy because of abnormal uterine bleeding or postmenopausal bleeding. The vaginoscopic approach was used in 19 patients (59%). Indications for direct aspiration endometrial biopsy included cervical stenosis, inability to pass the endometrial biopsy instrument into the uterine cavity, and patient intolerance of endometrial biopsy. Adequate endometrial samples were obtained in 28 patients (87.5%). In 3 of 4 patients in whom direct aspiration endometrial biopsy did not provide sufficient tissue, hysteroscopy revealed an atrophic-appearing endometrium. The direct aspiration endometrial biopsy diagnosis was confirmed in 5 of 7 patients who subsequently underwent dilation and curettage or hysterectomy. CONCLUSION: Direct aspiration endometrial biopsy is a simple and effective endometrial sampling method when traditional office-based endometrial biopsy is not feasible. Further prospective studies including larger populations are needed to confirm these results.

Measurement of endometrial stripe thickness by obstetrics and gynecology residents.

OBJECTIVE: How well do obstetrics and gynecology residents measure the endometrial stripe by transvaginal sonography? STUDY DESIGN: Three obstetrics and gynecology residents at the University of Texas Medical Branch from each year level were tested for their ability to perform endometrial stripe measurements. Measurements of endometrial stripe thickness within 1 mm of the reference value that was obtained by an expert sonographer were deemed to be correct. RESULTS: Residents correctly measured the endometrial stripe in 14 of 24 cases (58%). Postgraduate year-4 residents correctly measured endometrial stripe thickness in 5 of 6 cases (83%); lower level residents were correct in 9 of 18 cases (50%). The most common error that was noted was an incorrect image plane in 25 of 47 attempts (53%). Fewer errors were committed by upper level as compared with lower level residents (P < .05). CONCLUSION: By the end of residency, residents can accurately measure the endometrial stripe using transvaginal sonography. Emphasis should be placed on the improvement of the measurement skills.

Poor knowledge regarding the Pap test among low-income women undergoing routine screening.

CONTEXT: Many women undergoing cervical cancer screening lack appropriate understanding of the Pap test. It is important to evaluate knowledge and informational needs about Pap testing among groups who may have difficulty accessing care or a relatively low likelihood of obtaining follow-up for an abnormal result, such as minority and low-income women. METHODS: A sample of 338 women undergoing cervical screening at two clinics in Texas completed a questionnaire measuring their knowledge of Pap testing and asking what specific information they would like to know about the test. Group comparisons and qualitative analyses were conducted. RESULTS: Women correctly answered an average of 8.7 out of 20 questions; the range was 0-17. Mean scores were higher among white women (10.2) than among blacks (8.4) and Hispanics (7.4), among women with more than a high school education than among their less educated counterparts (10.0 vs. 7.9) and among women with an annual household income of at least $10,000 than among those with a lower income (9.3 vs. 8.4). Knowledge scores did not differ according to Pap history. Open-ended questioning identified a need for information on the purpose of the test, exam procedures, abnormal test results and prognosis. CONCLUSIONS: Minority women and those of low socioeconomic status had poor understanding of Pap testing. Identifying misunderstandings in this vulnerable population and improving patient education on the most basic aspects of Pap testing may increase adherence to follow-up when abnormalities are detected.

Detection of benign endometrial masses by endometrial stripe measurement in premenopausal women.

OBJECTIVE: Our objective was to estimate whether a transvaginal endometrial stripe of less than 5 mm in premenopausal women would exclude endometrial polyps and intracavitary leiomyomata, thereby eliminating the need for sonohysterography. METHODS: Data from 206 consecutive sonohysterograms performed in premenopausal women with abnormal uterine bleeding between August 1998 and October 2001 were collected retrospectively. Endometrial stripe measurements were obtained in the sagittal plane before sonohysterography. Baseline endometrial stripe images were reviewed by one of the authors, who was blinded to sonohysterography and pathology results, to evaluate for gross endometrial abnormalities on transvaginal ultrasonography. RESULTS: Endometrial stripe measurements were obtained before sonohysterography in 200 of the 206 consecutive exams in premenopausal subjects. Of the 80 subjects with an endometrial stripe measurement less than 5 mm, 11 had endometrial polyps and 5 had submucosal fibroids on sonohysterography. With an endometrial stripe thickness of less than 5 mm, the sensitivity was 74% (95% confidence interval 62-84), the specificity was 46% (95% confidence interval 38-54), the positive predictive value was 37%, and the negative predictive value was 80%. The detection of pathology was not improved by excluding cases with an abnormal-appearing endometrial stripe on the baseline transvaginal images. The use of other endometrial stripe cutoff values did not improve the diagnostic accuracy. CONCLUSION: Using an endometrial stripe cutoff of 5 mm in premenopausal women would miss significant intracavitary pathology. The sonographic evaluation of abnormal uterine bleeding in premenopausal women should include sonohysterography or equivalently accurate testing regardless of endometrial stripe thickness.

Efficacy of second versus third generation oral contraceptives in the treatment of hirsutism.

OBJECTIVE: To compare second versus third generation combination oral contraceptives (OCs) in the treatment of hirsutism. METHODS: Women with hirsutism, as defined by a minimum Ferriman-Gallwey score of 10, were randomized in a double-blind fashion to receive an OC containing either ethinyl estradiol/desogestrel or ethinyl estradiol/levonorgestrel for 9 months of treatment. Ferriman-Gallwey scores, androgen levels and sex hormone-binding globulin were measured at baseline and every 3 months for the duration of the study. Hormones were measured in duplicate by radioimmunoassay. RESULTS: Of the 47 women enrolled, 24 were randomized to ethinyl estradiol/desogestrel and 23 were randomized to ethinyl estradiol/levonorgestrel. Mean sex hormone-binding globulin increased significantly in subjects using the desogestrel-containing contraceptive compared with the levonorgestrel-containing contraceptive. Ten subjects completed the 9 months of treatment in the levonorgestrel group and 11 completed the study in the desogestrel group. Mean free testosterone and 3alpha-androstanediol glucuronide decreased significantly in the group receiving ethinyl estradiol/desogestrel but not in the ethinyl estradiol/levonorgestrel group. Mean Ferriman-Gallwey scores decreased significantly in both treatment groups. Improvement in mean Ferriman-Gallwey score was 35.7 +/- 38.1% (p < 0.001) for the ethinyl estradiol/desogestrel arm and 33.4 +/- 27.3% (p < 0.001) for the ethinyl estradiol/levonorgestrel arm. There were no statistically significant differences found in the improvement of Ferriman-Gallwey scores between the two treatment arms, although the power to detect a difference was limited by the small sample size. CONCLUSIONS: Treatment of hirsute women with third generation OCs containing desogestrel results in a significant increase in sex hormone-binding globulin and decrease in free testosterone and 3alpha-androstanediol glucuronide. Both second and third generation OCs were clinically effective in treating hirsutism.
