Mental Health Outcomes of Endometriosis Patients during the COVID-19 Pandemic: Impact of Pre-pandemic Central Nervous System Sensitization. THE JOURNAL OF PAIN 2024; 25:104481. [PMID: 38246253 DOI: 10.1016/j.jpain.2024.01.346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 01/16/2024] [Accepted: 01/16/2024] [Indexed: 01/23/2024]
Abstract
To correlate pain-related phenotyping for central nervous system sensitization in endometriosis-associated pain with mental health outcomes during the COVID-19 pandemic, the prospective Endometriosis and Pelvic Pain Interdisciplinary Cohort (ClinicalTrials.gov #NCT02911090) was linked to the COVID-19 Rapid Evidence Study of a Provincial Population-Based Cohort for Gender and Sex (RESPPONSE) dataset. The primary outcomes were depression (PHQ-9) and anxiety (GAD-7) scores during the pandemic. The explanatory variables of interest were the Central Sensitization Inventory (CSI) score (0-100) and endometriosis-associated chronic pain comorbidities/psychological variables before the pandemic. The explanatory and response variables were assessed for correlation, followed by multivariable regression analyses adjusting for PHQ-9 and GAD-7 scores pre-pandemic as well as age, body mass index, and parity. A higher CSI score and a greater number of chronic pain comorbidities before the pandemic were both positively correlated with PHQ-9 and GAD-7 scores during the pandemic. These associations remained significant in adjusted analyses. Increasing the CSI score by 10 was associated with an increase in pandemic PHQ-9 by .74 points (P < .0001) and GAD-7 by .73 points (P < .0001) on average. Each additional chronic pain comorbidity/psychological variable was associated with an increase in pandemic PHQ-9 by an average of .63 points (P = .0004) and GAD-7 by .53 points (P = .0002). Endometriosis patients with a history of central sensitization before the pandemic had worse mental health outcomes during the COVID-19 pandemic. As a risk factor for mental health symptoms in the face of major stressors, clinical proxies for central sensitization can be used to identify endometriosis patients who may need additional support. PERSPECTIVE: This article adds to the growing literature of the clinical importance of central sensitization in endometriosis patients, who had more symptoms of depression and anxiety during the COVID-19 pandemic. Clinical features of central sensitization may help clinicians identify endometriosis patients needing additional support when facing major stressors.

Abstract
OBJECTIVE The World Endometriosis Research Foundation established the Endometriosis Phenome and Biobanking Harmonisation Project (EPHect) to create standardized documentation tools (with common data elements) to facilitate the comparison and combination of data across different research sites and studies. In 2014, 4 data research standards were published: clinician-reported surgical data, patient-reported clinical data, and fluid and tissue biospecimen collection. Our current objective is to create an EPHect standard for the clinician-reported physical examination (EPHect-PE) for research studies. DESIGN An international consortium involving 26 clinical and academic experts and patient partners from 11 countries representing 25 institutions and organizations. Two virtual workshops, followed by the development of the physical examination standards underwent multiple rounds of iterations and revisions. SUBJECTS N/A MAIN OUTCOME MEASURE(S): N/A RESULT(S): The EPHect-PE tool provides standardized assessment of physical examination characteristics and pain phenotyping. Data elements involve examination of back and pelvic girdle; abdomen including allodynia and trigger points; vulva including provoked vestibulodynia; pelvic floor muscle tone and tenderness; tenderness on unidigital pelvic examination; presence of pelvic nodularity; uterine size and mobility; presence of adnexal masses; presence of incisional masses; speculum examination; tenderness and allodynia at an extra-pelvic site (e.g., forearm); and recording of anthropometrics. CONCLUSION(S) The EPHect-PE standards will facilitate the standardized documentation of the physical examination, including the assessment and documentation of examination phenotyping of endometriosis-associated pelvic pain.

A Systematic Review with a Narrative Synthesis. Reprod Sci 2024; 31:633-644.

Abstract
It has been suggested that central sensitization (CS) may be involved in the failure of standard medical and surgical treatment to relieve endometriosis-related pain. However, there is no gold standard for the diagnosis of CS, and self-reported questionnaires are used as diagnostic surrogates. The main objective of this review was to identify all CS questionnaires used in clinical endometriosis studies. The secondary objective was to qualitatively analyze strengths and weaknesses of each questionnaire. A PubMed and EMBASE systematic literature search conducted in April 2023 using the terms "endometriosis; central pain; central sensitization; questionnaire; patient-reported outcome measure; screening tool" identified 122 publications: six articles were included in the review. The Central Sensitization Inventory (CSI) is the most frequently used questionnaire for the detection of CS in patients with endometriosis. It has been validated in patients with endometriosis, in whom it appears to have good psychometric proprieties. The Fibromyalgia Survey Questionnaire (FSQ) has also been used, although it has not been specifically validated in endometriosis patients. The debate regarding these questionnaires' construct validity is still open and will be so until a gold standard diagnostic tool for CS is found. In fact, some authors argue these questionnaires are measuring psychological vulnerability and a hypervigilant state that is associated with pain, rather than CS itself. However, their use should not be discouraged as they are able to identify chronic pain patients which warrant further attention and who may benefit from broader treatment strategies.

Abstract
IMPORTANCE A subset of people who undergo surgery for endometriosis have persistent pain, suggesting that other factors besides the endometriosis, such as central sensitization, may play a role in this pain. The Central Sensitization Inventory, a validated self-reported questionnaire of central sensitization symptoms, may identify individuals with endometriosis who have more pain after surgery due to pain sensitization. OBJECTIVE To examine whether greater baseline Central Sensitization Inventory scores are associated with postsurgical pain outcomes. DESIGN, SETTING, AND PARTICIPANTS This prospective, longitudinal cohort study performed at a tertiary center for endometriosis and pelvic pain in British Columbia, Canada, included all patients aged 18 to 50 years with diagnosed or suspected endometriosis and a baseline visit between January 1, 2018, and December 31, 2019, who underwent surgery after the baseline visit. Individuals who were menopausal, had a prior hysterectomy, or were missing data for outcomes or measures were excluded. Data analysis was performed from July 2021 to June 2022. MAIN OUTCOMES AND MEASURES The primary outcome was chronic pelvic pain at follow-up measured on a scale of 0 to 10, with 0 to 3 indicating no pain or mild pain, 4 to 6 indicating moderate pain, and 7 to 10 indicating severe pain. Secondary outcomes were deep dyspareunia, dysmenorrhea, dyschezia, and back pain at follow-up. The main variable of interest was baseline Central Sensitization Inventory score (measured from 0 to 100, consisting of 25 self-reported questions rated from 0 to 4 [never, rarely, sometimes, often, and always, respectively]). RESULTS A total of 239 patients (mean [SD] age, 34 [7] years; 189 [79.1%] White [11 (5.8%) identified as White mixed with another ethnicity], 1 [0.4%] Black or African American, 29 [12.1%] Asian, 2 [0.8%] Native Hawaiian or Pacific Islander, 16 [6.7%] other, and 2 [0.8%] mixed race or ethnicity) with follow-up data at more than 4 months after surgery were included in this study (71.0% follow-up rate). The mean (SD) baseline Central Sensitization Inventory score was 43.8 (18.2), and the mean (SD) follow-up was 16.1 (6.1) months. Higher baseline Central Sensitization Inventory scores were significantly associated with higher chronic pelvic pain (odds ratio [OR], 1.02; 95% CI, 1.00-1.03; P = .02), deep dyspareunia (OR, 1.03; 95% CI, 1.01-1.04; P = .004), dyschezia (OR, 1.03; 95% CI, 1.01-1.04; P < .001), and back pain (OR, 1.02; 95% CI, 1.00-1.03; P = .02) at follow-up, when controlling for baseline pain scores. The Central Sensitization Inventory scores themselves decreased slightly from baseline to follow-up (mean [SD] score, 43.8 [18.2] vs 41.7 [18.9]; P = .05); however, individuals with high baseline Central Sensitization Inventory scores still had high scores at follow-up. CONCLUSIONS AND RELEVANCE In this cohort study of 239 patients with endometriosis, higher Central Sensitization Inventory scores at baseline were associated with worse pain outcomes after endometriosis surgery, when controlling for baseline pain scores. The Central Sensitization Inventory could be used to counsel patients with endometriosis on their expected outcomes after surgery.

OHNUT VS WAITLIST CONTROL FOR THE SELF-MANAGEMENT OF ENDOMETRIOSIS-ASSOCIATED DEEP DYSPAREUNIA: A PILOT RANDOMIZED CONTROLLED TRIAL PROTOCOL (Preprint). JMIR Res Protoc 2022; 12:e39834. [PMID: 36972117 PMCID: PMC10131731 DOI: 10.2196/39834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 01/19/2023] [Accepted: 01/24/2023] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND Endometriosis-associated deep dyspareunia is associated with reduced sexual quality of life, lower self-esteem, and impaired sexual function. OBJECTIVE The primary objective is to assess the acceptability of a phallus length reducer (brand name: Ohnut [OhnutCo]), which is a buffer worn over the penis or a penetrating object to reduce endometriosis-associated deep dyspareunia, and the feasibility of a definitive randomized controlled trial (RCT). The secondary objective is to obtain estimates of the effectiveness of the buffer. An embedded substudy will explore the acceptability and the preliminary validity and reliability of a vaginal insert for the self-assessment of deep dyspareunia. METHODS Ours is an investigator-initiated, 2-arm RCT. We will recruit 40 patient participants with diagnosed endometriosis between the ages of 19 and 49 years, as well as their sexual partners. The participating couples will be randomized in a 1:1 ratio into the experimental arm or the waitlist control arm. The length of the study period will be 10 weeks, during which time all participants will record deep dyspareunia severity following each episode of sexual intercourse. In weeks 1 to 4, all patient participants will record deep dyspareunia severity at each sexual encounter. In weeks 5 to 10, participants in the experimental arm will use the buffer during vaginal penetration; participants in the waitlist control arm will continue engaging in vaginal penetration as usual. Participants will complete questionnaires for assessing measures of anxiety, depression, and sexual function at baseline, at 4 weeks, and at 10 weeks. In the substudy, patient participants will self-assess dyspareunia by using a vaginal insert on 2 occasions, at least 1 week apart. The primary outcomes-the acceptability and feasibility of the buffer-will be assessed with descriptive statistics, and the secondary outcome-phallus length reducer effectiveness-will be assessed by using an analysis of covariance-based approach. For the vaginal insert, we will assess acceptability, test-retest reliability, and convergent validity via correlation analyses comparing the use of the insert to clinical examination in terms of dyspareunia assessment outcomes. RESULTS Our pilot will provide initial data on the acceptability and effectiveness of the buffer and the feasibility of the study methodology. The results from our study are expected to be submitted for publication by the spring of 2023. As of September 2021, we have consented 31 couples into the study. CONCLUSIONS Our study will provide preliminary evidence for the self-assessment and management of endometriosis-associated deep dyspareunia. The findings will inform the decision to proceed to a definitive RCT. TRIAL REGISTRATION ClinicalTrials.gov NCT04370444; https://clinicaltrials.gov/ct2/show/NCT04370444.

Abstract
Women with endometriosis often suffer from genito-pelvic pain. The objective of the present study was to analyze the relationship between cognitive and psycho-emotional factors and sexual functioning of women with endometriosis, comparing women with and without endometriosis. A total of 87 women with endometriosis (EG) and 100 women without endometriosis (CG) completed a socio-demographic questionnaire; the short-form of McGill Pain Questionnaire (SF-MPQ); the Female Sexual Functioning Index (FSFI); the Sexual Distress Scale (SDS); the Symptoms Checklist (SCL-90-R); the Toronto Alexithymia Scale (TAS-20); the Positive and Negative Affects Scale (PANAS); the Sexual Dysfunctional Belief Questionnaire (SDBQ); the Sexual Modes Questionnaire (SMQ); and the Questionnaire of Cognitive Schema Activation in Sexual Context (QCSASC). EG obtained worse scores than CG in SF-MPQ, Pain subscale of FSFI, and SDS. EG reached higher scores than CG on almost all scales of SCL-90-R and lower scores in the “Identifying Feelings” scale of TAS-20. Furthermore, EG reported more negative emotions toward sexuality than CG (PANAS) higher scores on the “Affection Primacy” scale of SDBQ and the “Helpless” sexual cognitive schema of QCSASC than CG. No significant differences were found in SMQ. Sexual health professionals should address psychological, emotional, and cognitive factors since they seem involved in patients’ sexual experiences.

Abstract
Background Up to 28% of endometriosis patients do not get pain relief from therapeutic laparoscopy but this subgroup is not defined. Objectives To identify any prognostic patient-specific factors (such as but not limited to patients’ type or location of endometriosis, sociodemographics and lifestyle) associated with a clinically meaningful reduction in post-surgical pain response to operative laparoscopic surgery for endometriosis. Search strategy PubMed, Cochrane and Embase databases were searched from inception to 19 May 2020 without language restrictions. Backward and forward citation tracking was used. Selection criteria, data collection and analysis: Cohort studies reporting prognostic factors, along with scores for domains of pain associated with endometriosis before and after surgery, were included. Studies that compared surgeries, or laboratory tests, or outcomes without stratification were excluded. Results were synthesised but variation in study designs and inconsistency of outcome reporting precluded us from doing a meta-analysis. Main results Five studies were included. Quality assessment using the Newcastle–Ottawa scale graded three studies as high, one as moderate and one as having a low risk of bias. Four of five included studies separately reported that a relationship exists between more severe endometriosis and stronger pain relief from laparoscopic surgery. Conclusion Currently, there are few studies of appropriate quality to answer the research question. We recommend future studies report core outcome sets to enable meta-analysis. Lay summary Endometriosis is a painful condition caused by displaced cells from the lining of the womb, causing inflammation and scarring inside the body. It affects 6–10% of women and there is no permanent cure. Medical and laparoscopic surgical treatments are available, but about 28% of patients do not get the hoped-for pain relief after surgery. Currently, there is no way of predicting who gets better and who does not. We systematically searched the world literature to establish who may get better, in order to improve counselling when women choose treatment options. We identified five studies of variable quality showing: More complex disease (in specialist hands) responds better to surgery than less, but more studies needed.

Abstract
Deep dyspareunia refers to pain with deep penetration or insertion into the vagina, which affects quality-of-life. The aim of this narrative review is to examine how the underlying conditions that give rise to deep dyspareunia, and the symptoms of these conditions, can affect sexual function and quality-of-life beyond the deep dyspareunia itself. For example, deep dyspareunia may be associated with gynaecological pathologies that cause cyclical pain symptoms (e.g dysmenorrhea, dyschezia/dysuria), resulting in quality-of-life changes related to menstrual cycle events such as ovulation or menstruation. Recurrent dysmenorrhea can cause hyperalgesic priming that sensitizes the nervous system, leading to chronic pelvic pain that can be exacerbated with sexual activity. The co-existence of functional bowel or bladder disorders can result in urgency and frequency that affect the sexual response cycle. Myofascial/musculoskeletal origins of deep dyspareunia may affect body positioning during sexual activity. Central nervous system sensitization can underlie these different factors, and also be associated with mental health conditions, which together can cause symptomatology across body systems that can affect all aspects of one's sexual life. Recognition and management of the far-reaching impacts of deep dyspareunia and its associated comorbidities may be important in clinical care to meaningfully improve quality-of-life. Future research should include a comprehensive empirical validation of the hypotheses and potential mechanisms in this review.

Abstract
ABSTRACT A key clinical problem is identifying the patient with endometriosis whose pain is complicated by central nervous system sensitization, where conventional gynecologic treatment (eg, hormonal therapy or surgery) may not completely alleviate the pain. The Central Sensitization Inventory (CSI) is a questionnaire previously validated in the chronic pain population. The objective of this study was an exploratory proof-of-concept to identify a CSI cutoff in the endometriosis population to discriminate between individuals with significant central contributors (identified by central sensitivity syndromes [CSS]) to their pain compared to those without. We analyzed a prospective data registry at a tertiary referral center for endometriosis, and included subjects aged 18 to 50 years with endometriosis who were newly or re-referred to the center in 2018. The study sample consisted of 335 subjects with a mean age of 36.0 ± 7.0 years. An increasing number of CSS was significantly correlated with dysmenorrhea, deep dyspareunia, dyschezia, and chronic pelvic pain scores (P < 0.001), and with the CSI score (0-100) (r = 0.731, P < 0.001). Receiver operating characteristic analysis indicated that a CSI cutoff of 40 had a sensitivity of 78% (95% CI: 72.7%-84.6%) and a specificity of 80% (95% CI: 70.3%-84.5%) for identifying a patient with endometriosis with ≥3 CSS. In the group with CSI ≥ 40, 18% retrospectively self-reported pain nonresponsive to hormonal therapy and 40% self-reported daily pain, compared with 6% and 20% in the CSI < 40 group (P = 0.003 and 0.002, respectively). In conclusion, a CSI ≥ 40 may be a practical tool to help identify patients with endometriosis with pain contributors related to central nervous system sensitization.

Abstract
ABSTRACT Hyperthermic intraperitoneal chemotherapy (HIPEC) has been used for decades as a treatment for disseminated abdominal malignancies, including pseudomyxoma peritonei and peritoneal mesothelioma. HIPEC had been used to treat recurrent ovarian cancer only when curative options were lacking, but new data indicate that it may be suitable as a primary treatment for patients with late-stage epithelial ovarian cancer, increasing the recurrence-free time interval and improving quality of life. However, treatment can be challenging because of patient trauma from surgery, combined with the toxicity and high temperature of the chemotherapeutic agents. This article reviews HIPEC and its targeted intraoperative and postoperative management.

Abstract
INTRODUCTION While two-thirds of women will experience dyspareunia and vaginal dilators are often used to treat dyspareunia, outside of a single case report, no study has investigated the potential of low-dose, high frequency movement-based dilator therapy for dyspareunia in premenopausal female patients. AIM To determine the utility of low-dose, high frequency movement-based dilator use for dyspareunia in premenopausal female patients. METHODS Retrospective study of women presenting to outpatient hospital-based pelvic floor physical therapy office in a tertiary care center. All adult premenopausal female patients who were referred to pelvic floor physical therapy for dyspareunia and completed movement-based dilator therapy (MBDT) and met study criteria (n = 26) were included for analysis. MAIN OUTCOME MEASURE Patient change in pain level status using Numeric Pain Rating Scale with intercourse was compared between initial evaluation and time of discharge from pelvic floor physical therapy. RESULTS Among the 26 women who met criteria for this study, the average pain score decreased from 8.3 (SD 2.2) before treatment to 1.3 (SD 2.0) after treatment and was statistically significant (P< .001). Complete resolution of dyspareunia was reported in 58% of patients. Patients completed between 2 and 6 total pelvic floor physical therapy visits (average 3.7, SD1.5), over 0-44 weeks (mean 9.6 weeks, SD 8.3). CONCLUSION Low-dose, high frequency, movement-based dilator therapy significantly reduced or resolved the experience of pain with penetrative vaginal intercourse with dyspareunia. Future prospective studies with larger samples and the inclusion of sexual functional status should be considered to explore the full potential of this modality in treatment of premenopausal patients with dyspareunia.

Abstract
INTRODUCTION Endometriosis is a chronic gynecological disease that affects women's quality of life, sexuality, and relationship. Endometriosis-associated pain plays an essential role in well-being impairment. The present review aimed to analyze literature about endometriosis-associated pain and quality of life, sexual health, and quality of the relationship, assessing the role of the biopsychosocial factors involved and the women's pain experience. EVIDENCE ACQUISITION Bibliographic research of relevant articles published from 2015 to 2020 in PubMed, Google Scholar, Web of Science, Scopus, EBSCO, and Cochrane Library. EVIDENCE SYNTHESIS Endometriosis is associated with impairing all women's quality of life domains, and pain appears to be the most influential variable. The pain mechanism is not simple and implies several biological, psychological, and social factors. Women's sexual health is also impaired, and patients report dyspareunia, sexual dysfunctions, dissatisfaction, and distress. Partners' sexual well being is compromised as well. Endometriosis negatively influences relationship quality, and the illness burden affects both couple members. CONCLUSIONS A multidisciplinary team using a couple-centered and a biopsychosocial approach is crucial to provide appropriate treatment for endometriosis-associated pain. A better comprehension of all bio-psycho-social aspects implicated in women's well-being and pain experience needs more research.

Abstract
Endometriosis is a chronic, inflammatory disease affecting more than 170 million women worldwide and up to 10% of women of reproductive age. As a consequence of inflammatory reaction and infiltration of anatomic structures, endometriosis can cause “pain symptoms” including dysmenorrhea, dyspareunia, dyschezia, dysuria, and chronic pelvic pain. In this review, we summarized the impact of endometriosis on quality of life in all its aspects including sexual life, work, and social relationships. The data research was conducted using web-based search engines and/or various electronic research databases querying for all articles related to endometriosis and quality of life from the inception of the database up to February 2020. Endometriosis has not only physical but also psychological effects, causing depression, anxiety, and compromising social relationships. Furthermore, endometriosis negatively impacts sexual life and social relationships. At last, the economic burden of endometriosis should not be underestimated, both individually and for the community, as this pathology leads to a loss of productivity at work and large use of health resources. Thus, endometriosis-related symptoms control women’s lives compromising the quality of life in all aspects. In this review, we summarized the impact of endometriosis on various aspects of women’s lives.

Abstract
Background The quality of life (QoL) of patients with endometriosis and infertility was assessed in different stages and correlated with the clinical features of the cases. Methods The present study was a cross-sectional study; 106 women were included, divided in two endometriosis groups (Grade I/II, 26 women, and Grade II/IV, 74 women). All participants attended the Endometriosis and Infertility Outpatient Clinic of the Instituto Ideia Fértil de Saúde Reprodutiva, Faculdade de Medicina do ABC, São Paulo, Brazil, were and responded to the Short Form (SF) Health Survey-36. Convenience sampling was used due to the authors’ access to the study population; however, the sample number was calculated to be sufficient for 95% power in both groups. Results Homogeneity was observed between Grade I/II and Grade III/IV staging, with similar mean ages (35.27, ±3.64 years and 34.04, ±3.39 years, respectively, p = 0.133); types of infertility (p = 0.535); infertility time (p = 0.654); degrees of pain (p = 0.849); and symptoms common to endometriosis, namely, dysmenorrhea (p = 0.841), dyspareunia (0.466), chronic pelvic pain (p = 0.295), and intestinal (p = 0.573) or urinary (p = 0.809) diseases. Comparisons of median scores in the QoL domains demonstrated that the distributions of QoL and clinical symptoms were significantly related between the types of dyspareunia and the following domains: physical functioning (p = 0.017), role- emotional (p = 0.013), and general health (p = 0.001). Regarding pain outside of menstruation, there was significance in the pain domain (p = 0.017), and degree of pain was significance in physical functioning (p = 0.005) and role-physical (p = 0.011) domains. Conclusions The present study pointed out that it is not the stage of endometriosis that interferes in the quality of life of women with endometriosis and infertility but rather the clinical manifestations, such as dyspareunia and pain. Thus, we can conclude that the patient’s perception of the disease should be considered in health care and that the losses are independent of the degree of endometriosis in this population with the aggravating factor of infertility.

Abstract
STUDY QUESTION What are the use patterns and factors associated with combined hormonal contraception (CHC) ineffectiveness or discontinuation due to side-effects in patients with endometriosis and pelvic pain? SUMMARY ANSWER Worse chronic pelvic pain (CPP) severity and pelvic floor myalgia were associated with continuous CHC ineffectiveness, while poorer quality-of-life was associated with continuous CHC discontinuation due to side-effects. WHAT IS KNOWN ALREADY CHC is a first line of therapy for endometriosis-associated pelvic pain in women. However, some patients state that CHC is ineffective for their pain, while others have to discontinue CHC due to side-effects. STUDY DESIGN, SIZE, DURATION Analysis of a prospective patient database from a tertiary care referral center for patients with endometriosis and pelvic pain between December 2013 and April 2015 was carried out. PARTICIPANTS/MATERIALS, SETTING AND METHODS A total of 373 patients of reproductive age with endometriosis from the database were included in the study. Data included patient self-reported questionnaires, physical examination findings and validated instruments. There were four variables of interest: history of cyclical CHC ineffectiveness (yes/no), history of cyclical CHC discontinuation due to side-effects (yes/no), history of continuous CHC ineffectiveness (yes/no) and history of continuous CHC discontinuation due to side-effects (yes/no). The primary outcome was CPP severity for the past 3 months (score of 0–10), and secondary outcomes were other pelvic pain scores, quality-of-life on the Endometriosis Health Profile 30 (EHP-30) and underlying conditions including irritable bowel syndrome, painful bladder syndrome, abdominal wall pain, pelvic floor myalgia and depression, anxiety and pain catastrophizing. MAIN RESULTS AND THE ROLE OF CHANCE Among the 373 cases in the dataset, prior cyclical CHC use was reported by 228 (61.1%) women, of which 103 (27.6%) stated it was ineffective for their pain and 94 (25.2%) stated they discontinued CHC due to side-effects. Previous continuous CHC use was reported by 175 (46.9%) women, of which 67 (18.0%) stated it was ineffective and 59 (15.8%) stated they discontinued due to side-effects. Worse CPP severity in the last 3 months was associated with a history of continuous CHC ineffectiveness (P < 0.001). Poorer quality-of-life was present in women who reported a history of continuous CHC discontinuation due to side-effects (P = 0.005). Among the underlying conditions, pelvic floor tenderness (as a marker of pelvic floor myalgia) was associated with CHC ineffectiveness. LIMITATIONS AND REASONS FOR CAUTION This study involved patient recall and no longitudinal follow-up. Also, we do not have data on the type of side-effect that led to discontinuation. Medication ineffectiveness was reported subjectively by the patient rather than using standardized criteria. Finally, the diagnosis of endometriosis was based on previous surgery or a current nodule or endometrioma on examination/ultrasound; without prospective surgical data on all the patients, it was not possible to do a sub-analysis by current surgical features (e.g. stage). WIDER IMPLICATIONS OF THE FINDINGS In women with endometriosis, CHC ineffectiveness was associated with worse CPP and pelvic floor myalgia, which suggests myofascial or nervous system contributors to CPP that does not respond to hormonal suppression. A tender pelvic floor, as a sign of pelvic floor myalgia, may be a clinical marker of patients with endometriosis who are less likely to have an optimal response to hormonal suppression. For women who discontinue CHC due to side-effects, research is needed to help alleviate these side-effects as these patients report worse quality-of-life.

Abstract
INTRODUCTION Deep dyspareunia, a common symptom in endometriosis, has previously been associated with bladder and/or pelvic floor tenderness (BPFT), which suggests a role for central nervous system sensitization. The Central Sensitization Inventory (CSI, 0-100) is a validated self-reported scale for patients with central sensitization. AIM The objective of this study was to phenotype deep dyspareunia using BPFT and the CSI. METHODS The methods included cross-sectional analysis from a prospective registry from January 2018 to June 2018 at a tertiary center for endometriosis (ClinicalTrials.gov #NCT02911090). Included were women aged 18-50 years with endometriosis (previously surgically diagnosed, current visualized endometrioma on ultrasound, or current palpable or visualized nodule on ultrasound), who were newly or re-referred to the center. Severity of deep dyspareunia was self-reported using an 11-point numeric rating scale (0 = no pain; 10 = worst pain imaginable), categorized as no or low deep dyspareunia (0-4) and high deep dyspareunia (5-10). We identified the subgroup with high deep dyspareunia and presence of BPFT, where we hypothesized a central component of the sexual pain. This subgroup was compared with 2 other subgroups: no or low deep dyspareunia and high deep dyspareunia but no BPFT. The CSI was compared between the groups using analysis of variance, followed by post hoc testing (P < .05). MAIN OUTCOME MEASURE The main outcome measure was the CSI score ranging from 0 to 100. RESULTS Data from 163 women with endometriosis were analyzed. The mean age of this cohort was 36.4 ± 6.8 years, and the mean CSI score was 41.0 ± 18.6. 37 percent (61/163) had high deep dyspareunia and BPFT; 29% (47/163) had high deep dyspareunia and no BPFT; and 34% (55/163) had no or low deep dyspareunia. The CSI significantly differed between the 3 groups (analysis of variance: F = 22.4, P < .001). In post hoc testing, the CSI was higher in women with high deep dyspareunia and BPFT (51.3 ± 16.9), compared with women with no or low deep dyspareunia (30.9 ± 15.4, P < .001) and compared with women with high deep dyspareunia but no BPFT (39.4 ± 17.2, P = .001). CLINICAL IMPLICATIONS The CSI could be used to classify and phenotype patients with endometriosis-associated sexual pain. STRENGTH & LIMITATIONS Strengths include a prospective registry with integrated pain scores, validated questionnaires, and physical examination findings. Limitations include the lack of quantitative sensory testing for central sensitization. CONCLUSIONS In women with endometriosis, the subgroup with high deep dyspareunia and bladder and/or pelvic floor tenderness had a significantly higher score on the CSI than other subgroups, suggesting that this group may have a central component to their sexual pain.

Abstract
We conducted an observational study between March 2015 and March 2018 in our academic center. Symptomatic, sexually active women with clinical and sonographic diagnosis of deep infiltrating endometriosis (DIE) or isolated ovarian endometriosis were enrolled. Women were asked to rank endometriosis-related symptoms, especially superficial and deep dyspareunia. Moreover, 3D transperineal ultrasound was performed to assess the levator hiatus area (LHA) evaluating pelvic floor muscle (PFM) morphometry. Women with endometriosis seem to have a high prevalence of superficial dyspareunia and three-dimensional transperineal ultrasound seems to be a viable technique to assess PFM morphometry in these women.

Abstract
INTRODUCTION Pelvic pain and vulvar pain are common conditions in women. In this study, we sought to characterize the clinical picture of patients with concurrent pelvic pain and provoked vestibulodynia (PVD). AIM To analyze the association between sexual/clinical characteristics and a diagnosis of PVD among women with pelvic pain. METHODS Cross-sectional analysis of a prospective registry at a tertiary referral center for pelvic pain and endometriosis, involving consecutive non-menopausal sexually active patients 18-49 years-old seen by a single gynecologist from January 2016-December 2017. The sample was divided into 2 groups: pelvic pain with PVD; and pelvic pain alone (without PVD). MAIN OUTCOME MEASURES Superficial dyspareunia and deep dyspareunia on a 11-point numeric rating scale, and the sexual quality-of-life subscale of the Endometriosis Health Profile-30 (0-100%). RESULTS There were 129 patients that met study criteria: one third with pelvic pain and PVD (n = 42) and two-thirds with pelvic pain alone (without PVD) (n = 87). Women with pelvic pain and PVD had significantly more severe superficial dyspareunia ≥7/10 (OR = 12.00 (4.48-32.16), P < .001), more severe deep dyspareunia ≥7/10 (OR = 4.08 (1.83-9.10), P = .001), and poorer sexual quality of life (Endometriosis Health Profile-30 ≥50%) (OR = 4.39 (1.67-11.57), P = .002), compared with the group with pelvic pain alone. Women with pelvic pain and PVD also had more anxiety, depression, and catastrophizing, more frequent tenderness of the bladder and pelvic floor, and more common diagnosis of painful bladder syndrome. On the other hand, there were no significant differences between the 2 groups in terms of dysmenorrhea, chronic pelvic pain, abdominal wall allodynia, positive Carnett test for abdominal wall pain, functional quality of life, endometriosis, and irritable bowel syndrome. CONCLUSIONS In the pelvic pain population, PVD may be associated with more negative impact on dyspareunia, sexual quality of life, and bladder/pelvic floor function, but it may not significantly impact abdominopelvic pain or day-to-day function in general.

Deep Dyspareunia: Review of Pathophysiology and Proposed Future Research Priorities. Sex Med Rev 2019; 8:3-17.

Abstract
INTRODUCTION Dyspareunia has been traditionally divided into superficial (introital) dyspareunia and deep dyspareunia (pain with deep penetration). While deep dyspareunia can coexist with a variety of conditions, recent work in endometriosis has demonstrated that coexistence does not necessarily imply causation. Therefore, a reconsideration of the literature is required to clarify the pathophysiology of deep dyspareunia. AIMS To review the pathophysiology of deep dyspareunia, and to propose future research priorities. METHODS A narrative review after appraisal of published frameworks and literature search with the terms (dyspareunia AND endometriosis), (dyspareunia AND deep), (dyspareunia AND (pathophysiology OR etiology)). MAIN OUTCOME VARIABLE Deep dyspareunia (present/absent or along a pain severity scale). RESULTS The narrative review demonstrates potential etiologies for deep dyspareunia, including gynecologic-, urologic-, gastrointestinal-, nervous system-, psychological-, and musculoskeletal system-related disorders. These etiologies can be classified according to anatomic mechanism, such as contact with a tender pouch of Douglas, uterus-cervix, bladder, or pelvic floor, with deep penetration. Etiologies of deep dyspareunia can also be stratified into 4 categories, as previously proposed for endometriosis specifically, to personalize management: type I (primarily gynecologic), type II (nongynecologic comorbid conditions), type III (central sensitization and genito-pelvic pain/penetration disorder), and type IV (mixed). We also identified gaps in the literature, such as lack of a validated patient-reported questionnaire or an objective measurement tool for deep dyspareunia and clinical trials not powered for sexual outcomes. CONCLUSION We propose the following research priorities for deep dyspareunia: deep dyspareunia measurement tools, inclusion of the population avoiding intercourse due to deep dyspareunia, nongynecologic conditions in the generation of deep dyspareunia, exploration of sociocultural factors, clinical trials with adequate power for deep dyspareunia outcomes, partner variables, female sexual response, pathways between psychological factors and deep dyspareunia, and personalized approaches to deep dyspareunia.

Abstract
The purpose of this study was to identify and localize mucosal epithelial progenitor cells (EPCs) in the rat vagina. Rat vagina was obtained from f77emale Sprague-Dawley rats (12 weeks old, n = 20). To identify EPCs in vagina, we followed a single-cell isolation protocol and analyzed the number of cells staining positive for EPC markers by flow cytometry. The expression of EPC-specific markers (CD44, ERα, PR) was evaluated by immunofluorescence. As shown by confocal immunofluorescence, CD44/ERα double-labeled cells were mainly expressed in the basal cell and suprabasal cell layers. Immunofluorescent staining of CD44 was expressed in the plasma membrane of the vaginal epithelium, and ERα was expressed in the cytoplasm of the vaginal epithelium. The CD44/ERα double-positive cells were noted in the rat vagina by flow cytometric analysis. PR-labeled cells were localized in the intermediate layer of the epithelial space of the vagina. The results revealed the existence of EPCs in the vagina. These findings imply that resident EPCs may have a role in the regeneration of vaginal mucosa.
