Comparing Vestibule Examination Techniques: Light Touch, Serial Forces, and the Lidocaine Test

Genitourinary Syndrome of Menopause: Pathophysiology, Clinical Presentation, and Differential Diagnosis

Scientific information is incomplete regarding the genitourinary syndrome of menopause. Both the lower genital and urinary tracts are rich in receptors for reproductive hormones and are highly susceptible to waning ovarian hormones at menopause. Symptoms of dryness and pain emerge in late perimenopause, but they can also result earlier from cancer therapies or bilateral oophorectomy. Lower urinary tract symptoms rise in prevalence at midlife and increase further with advancing age. Because ovarian senescence is typically followed by years of aging, some postmenopausal complaints may be attributable to increasing longevity.

Preferred physical characteristics of lidocaine thin film for women with vestibulodynia

Introduction

Vestibulodynia (VBD) is the most common cause of sexual pain in the United States, affecting up to 15% of reproductive-aged women during their lifetime with limited treatment options. The purpose of this study was to describe ideal physical characteristics of a vulvar film designed for insertional sexual pain in sexually active women with VBD.

Methods

Twenty women were recruited to participant in one of six, semi-structured 60-minute focus group discussions regarding treatment options for VBD. Heterosexual women, aged 18-51 years old with a diagnosis of vulvodynia, vestibulodynia or insertional dyspareunia fit the inclusion criteria. Those who reported no episodes of vaginal intercourse in the prior 18 months were excluded. A new vulvar film technology loaded with 50 mg of 5% lidocaine was introduced to the group. Participants took part in focus groups on a rolling basis depending on availability. Focus group discussions were audio-recorded and transcribed verbatim. Two study investigators coded the transcripts using inductive coding and merged their respective projects to resolve disagreements. We analyzed data related to each code to develop code clusters and higher-level primary topics regarding device preferences. Data related to each of these primary topics was analyzed to assess the range of participant attitudes and preferences and to identify patterns within each primary topic.

Results

One hundred and sixteen women were recruited, and twenty women were enrolled. The mean age for the participants was 33.3 years. Most women were educated with at least some college (93%), White (78.6%), married (75%), and had income greater than $100,000 (50%). Analysis of the focus group discussions identified five common topics addressed by participants: desired loaded medication, film size, film shape, film flexibility, and ease and accuracy of use. Concerns across topics included comfort, sexual spontaneity, and efficacy. Interest in loading the device with other acceptable medications or combination with lidocaine was independently noted in 2/6 (33%) of the focus groups.

Discussion

Mucoadhesive vulvar thin films may be an acceptable drug delivery system for insertional sexual pain for women with VBD.

Treating where it hurts-a randomized comparative trial of vestibule estradiol for postmenopausal dyspareunia

OBJECTIVE

To compare efficacies of two strengths of estradiol cream applied to the vulvar vestibule and use of silicone lubricant to reduce intercourse pain scores in postmenopausal women with moderate/severe dyspareunia.

METHODS

This pilot randomized comparative trial assigned 50 women to nightly applications of estradiol cream, 50 or 100 μg, for 12 weeks. We asked women to have lubricated penetration twice weekly, with intercourse or performing a tampon test. Pain, recorded in dairies, was rated using the 0-10 Numerical Rating Scale. We assessed biopsychosocial outcomes, urinary symptoms, and measured serum estradiol levels and endometrial stripe thicknesses. We performed physical examinations to determine tenderness levels of the vestibule, vagina, pelvic floor muscles, bladder, uterus, and adnexa. Comparisons were made using two-sample t test, Wilcoxon rank-sum test, or χ2 /Fisher's exact test.

RESULTS

Forty-seven women (94%), with a mean age of 59.7 years, completed the trial. The baseline median intercourse pain score was 8/10 (interquartile range, 6, 8). After 12 weeks, we measured no statistically significant difference between groups in the primary outcome, intercourse pain score, or any secondary outcome measure. For both groups together, the median intercourse pain score diminished by 50% after 4 weeks and 75% after 12 weeks ( P < 0.001). The most tender anatomic area, the vulvar vestibule, improved by 82% to 100% ( P < 0.001) with therapy. We did not measure a statistically significant difference in serum estradiol levels or endometrial stripe thickness between groups.

CONCLUSION

Estradiol cream applied to the vulvar vestibule, paired with precoital silicone lubricant, is a promising alternative to vaginal therapy for dyspareunia.

Where does postmenopausal dyspareunia hurt? A cross-sectional report

OBJECTIVE

A common symptom of genitourinary syndrome of menopause (GSM) is dyspareunia, attributed to vulvovaginal atrophy. Our objective was to systematically describe the pain characteristics and anatomic locations of tenderness in a cohort with moderate/severe dyspareunia likely due to GSM.

METHODS

This cross-sectional study reports the baseline data of postmenopausal women with dyspareunia screened for an intervention trial of topical estrogen. Postmenopausal women not using hormone therapy who had moderate or severe dyspareunia were eligible if estrogen was not contraindicated. Biopsychosocial assessments were performed using the Vulvar Pain Assessment Questionnaire, and participants underwent a systematic vulvovaginal examination that included a visual assessment and cotton swab testing for tenderness rated using the Numerical Rating Scale (0-10). Vaginal pH and mucosal sensitivity were assessed; pelvic floor muscles and pelvic viscera were palpated for tenderness.

RESULTS

Fifty-five eligible women were examined between July 2017 and August 2019. Mean age was 59.5 ± 6.8 years, and duration of dyspareunia was 6.2 ± 4.3 years. The mean intercourse pain score was 7.3 ± 1.8, most often described as "burning" and "raw." Ninety-eight percent had physical findings of vulvovaginal atrophy. Median pain scores from swab touch at the vulvar vestibule (just outside the hymen) were 4 to 5/10, and topical lidocaine extinguished pain. Median vaginal mucosal pain was zero.

CONCLUSIONS

Participants described their pain as "burning" and "dry." Tenderness was most severe and most consistently located at the vulvar vestibule. Correlating the symptom of dyspareunia with genital examination findings may further our understanding of treatment outcomes for GSM.
