Abstract Objective: We studied eight mental health conditions diagnosed before bilateral oophorectomy performed for nonmalignant indications. Methods: We identified 1,653 premenopausal women who underwent bilateral oophorectomy for a nonmalignant indication in Olmsted County, Minnesota, during a 20-year period (1988-2007). Each woman was matched by age (±1 year) to one population-based control who had not undergone bilateral oophorectomy before the index date (age range: 21-49 years). Both cases and controls were identified using the records-linkage system of the Rochester Epidemiology Project (REP http://www.rochesterproject.org). For eight mental health conditions, we calculated odds ratios (ORs) and their 95% confidence intervals (95% CIs) adjusted for race, education, and income using conditional logistic regression. Results: Pre-existing mood disorders, anxiety disorders, and somatoform disorders were associated with increased risk of bilateral oophorectomy in overall analyses. These associations were also significant in women ≤45 years of age at index date. Personality disorders were associated with increased risk only in overall analyses and adjustment disorders only in women 46 to 49 years of age. Some of the associations were significantly different across strata by age at index date and by indication. There was also a linear trend of increasing adjusted ORs from 1.55 (95% CI 1.31-1.83) for one mental health condition to 2.19 (95% CI 1.40-3.41) for three or more conditions (trend P < 0.001). Conclusions: We identified several mental health conditions that were associated with bilateral oophorectomy for nonmalignant indications. Awareness of these associations may guide women and physicians in future decision-making and limit unindicated bilateral oophorectomies. Video Summary: http://links.lww.com/MENO/A458.

Abstract Objective: The aim of this research was to study the long-term risk of de novo mental health conditions in women who underwent hysterectomy with bilateral ovarian conservation compared with age-matched referent women. Methods: Using the Rochester Epidemiology Project records-linkage system, we identified a historical cohort of 2,094 women who underwent hysterectomy with ovarian conservation for benign indications at age ≥18 years and with an index date between 1980 and 2002 in Olmsted County, Minnesota. Each woman was age-matched (±1 y) to a referent woman residing in the same county who had not undergone hysterectomy or any oophorectomy before the index date. These two cohorts were followed historically to identify de novo mental health conditions. We estimated hazard ratios (HRs) and 95% confidence intervals (95% CIs) using Cox proportional hazards models adjusted for 20 preexisting chronic conditions and other potential confounders. We also calculated absolute risk increases (ARIs) and reductions (ARRs) at 30 years of follow-up. Results: Over a median follow-up of 21.9 years, women who underwent hysterectomy at any age experienced increased risks of de novo depression (adjusted HR 1.26; 95% CI, 1.12-1.41; ARI 6.6%) and anxiety (adjusted HR 1.22; 95% CI, 1.08-1.38; ARI 4.7%). The association for depression increased significantly with younger age at hysterectomy, but did not vary significantly by indication. Interactions were not significant for anxiety. Conclusions: Hysterectomy, even with ovarian conservation, is associated with an increased long-term risk of de novo depression and anxiety, especially when performed in women who are younger.

ABSTRACT Background Vaginal diazepam is frequently used to treat pelvic floor tension myalgia and pelvic pain despite limited knowledge of systemic absorption. Aim To determine the pharmacokinetic and adverse event profile of diazepam vaginal suppositories. Methods We used a prospective pharmacokinetic design with repeated assessments of diazepam levels. Eight healthy volunteers were administered a 10-mg compounded vaginal diazepam suppository in the outpatient gynecologic clinic. Serum samples were collected at 0, 45, 90, 120, and 180 minutes; 8, 24, and 72 hours; and 1 week following administration of a 10-mg vaginal suppository. The occurrence of adverse events was assessed using the alternate step and tandem walk tests, the Brief Confusion Assessment Method, and numerical ratings. Plasma concentrations of diazepam and active long-acting metabolites were measured. Pharmacokinetic parameters were calculated by standard noncompartmental methods. Results The mean peak diazepam concentration (Cmax) of 31.0 ng/mL was detected at a mean time (Tmax) of 3.1 hours after suppository placement. The bioavailability was found to be 70.5%, and the mean terminal elimination half-life was 82 hours. The plasma levels of temazepam and nordiazepam peaked at 0.8 ng/mL at 29 hours and 6.4 ng/mL at 132 hours, respectively. Fatigue was reported by 3 of 8 participants. Clinical Implications Serum plasma concentrations of vaginally administered diazepam are low; however the half-life is prolonged. Strengths & Limitations Strengths include use of inclusion and exclusion criteria aimed at mitigating clinical factors that could adversely impact diazepam absorption and metabolism, and the use of an ultrasensitive LC-MS/MS assay. Limitations included the lack of addressing the efficacy of vaginal diazepam in lieu of performing a pure pharmacokinetic study with healthy participants. Conclusion Vaginal administration of diazepam results in lower peak serum plasma concentration, longer time to peak concentration, and lower bioavailability than standard oral use. Providers should be aware that with diazepam’s long half-life, accumulating levels would occur with chronic daily doses, and steady-state levels would not be reached for up to 1 week. This profile would favor intermittent use to allow participation in physical therapy and intimacy.

Abstract Background: Endometrial cancer (EC) is the most common gynecologic malignancy in developed countries and the incidence and mortality of EC continue to rise in the US. When detected early, EC is highly curable, suggesting that early detection strategies could reduce EC mortality. Women who develop EC often have a prolonged history of abnormal bleeding, offering a window for identifying many at-risk women prior to the development of advanced cancer. To evaluate risk prediction, novel sampling and early detection strategies in women at increased risk of EC, we established a prospective cohort of women with abnormal bleeding that is followed for endometrial hyperplasia and cancer endpoints. Methods: We consecutively enrolled women ≥45 years old presenting to the Mayo Clinic for evaluation of abnormal uterine bleeding (AUB), postmenopausal bleeding (PMB), thickened endometrial stripe (ES) on imaging, or Lynch Syndrome (LS). From all women, an intravaginal tampon and an endometrial brushing via Tao brush were collected before endometrial biopsy. Epidemiological EC risk factor data, clinical data, and endometrial biopsy histology results were abstracted from medical records. Absolute risk of endometrial hyperplasia and EC were calculated overall and in strata based on clinical symptoms and risk factors. Results: Among the first 1,000 women enrolled into the study, 712 (71%) were overweight or obese, 534 (53%) were postmenopausal, and 214 (22%) were current hormone replacement therapy (HRT) users. Endometrial biopsy and, if indicated, subsequent hysterectomy, detected 39 ECs, 16 atypical hyperplasias, and 28 hyperplasias without atypia at baseline evaluation. Among 534 postmenopausal women, 453 (85%) reported any type of bleeding, with spotting (39%) and light bleeding (27%) being more common than heavy bleeding (14%). Among perimenopausal women with AUB (n=452), the absolute risk of EC at baseline was 0.9% and among women with PMB, the absolute risk of EC at baseline was 7.5%. Among women with PMB, EC risk was modified by HRT use (risk of 2.6% in women on HRT and 8.2% in women not on HRT, respectively), obesity (risk of 5.3%, 8.1% and 9.5% for women with normal, overweight, and obese BMI, respectively), and type of bleeding (risk of 9.7%, 4.9%, and 8.2% in women with spotting, light or heavy bleeding, respectively). Discussion: While risk of endometrial cancer in perimenopausal women with AUB is low, approximately 8% of women presenting for clinical work up of PMB have underlying EC. Clinical presentation and risk factors modify the absolute risk of EC and may inform clinical management. Additional recruitment and prospective follow-up is underway to improve estimates of short- and long-term EC risk in women with PMB. With its collection of tampon and Tao brush samples, the study will provide a unique resource to evaluate molecular markers of EC and EC risk in elevated-risk women. Citation Format: Nicolas A.

INTRODUCTION: Bimanual pelvic examination is often performed for symptoms related to uterine fibroids (UF). We evaluated the clinical utility of this exam at the time of UF diagnosis in a community setting. METHODS: Retrospective sample of women diagnosed with UF between 2006 and 2010 in the Rochester Epidemiology Project, a population-based records-linkage system. Cohort includes a sample of women who had a pelvic examination within 12 months of UF diagnosis (n=141). Abnormal pelvic exam was defined as abnormal uterine size or shape, or any adnexal mass or fullness recorded by healthcare provider. We examined clinical and imaging characteristics using chi-squared for categorical and t tests for continuous data. Data reported as percentage or mean ± standard deviation. Volumes of the uterus and largest fibroid were calculated using the prolate ellipsoid formula. RESULTS: Women with UF and a normal pelvic exam (n=73) were younger than women with abnormal exam (n=68) (44.7±7.1 vs 46.9±5.4 years, P=.05), and had a higher BMI (29.4 ± 6.5 vs 26.6 ± 5.0 kg/m2, P=.007). Women with abnormal exam had significantly larger uterine volumes (226.0 ± 151.8 vs 150.9 ± 97.9 cm³, P=.005) and fibroid volumes (61.1±81.1 vs 19.9±52.8 cm³, P=.005). Abnormal examination was more frequently documented by gynecology providers (57.4%) than other providers (42.7%, P=.04). Fibroid symptoms were not associated with abnormal examination. CONCLUSION: Fifty-two percent of women with fibroids had a normal bimanual examination. Thus, a high suspicion of fibroids should prompt imaging. Lower BMI and larger uterine and fibroid dimensions increase fibroid diagnosis on pelvic examination.
