Psychology of Chronic Pelvic Pain: Prevalence, Neurobiological Vulnerabilities, and Treatment

Effect of dry needling on pain and central sensitization in women with chronic pelvic pain: A randomized parallel-group controlled clinical trial

Chronic pelvic pain (CPP) is a debilitating problem in women with clear evidence of myofascial dysfunction. It seems that Myofascial trigger points (MTrPs) contribute to the development of central sensitization (CS). This study aimed to investigate the effect of dry needling on pain and CS in women with CPP. Thirty-six women with CPP participated in this randomized controlled clinical trial and randomly assigned into three groups: dry needling group (DNG), placebo needling group (PNG) and control group (CG). The DNG received five sessions of DN using the "static needling", the PNG received non-penetrating method, and the CG did not receive any intervention. Assessment of outcomes including central sensitization inventory (CSI), short-form McGill pain questionnaire (SF-MPQ), electroencephalography (EEG), conditioned pain modulation (CPM), salivary cortisol concentration, 7-item general anxiety disorder scale (GAD-7), pain catastrophizing scale (PCS), and SF-36 questionnaire was performed pre-intervention, post-intervention, and three months post-intervention by a blind examiner. The result showed a significant group-by-time interaction for CSI, SF-MPQ, and PCS. There was a significant decrease in CSI score in post-intervention and three-months post-intervention compare to pre-intervention in the DNG and PNG. SF-MPQ-PPI score in DNG significantly decreased post-intervention. PCS-Total score decreased significantly post-intervention in DNG and PNG. No significant group-by-time interactions were observed for other variables. EEG results showed regional changes in the activity of frequency bands in both eye closed and eye open conditions. It seems that DN can affect central pain processing by removing the source of peripheral nociception.

Using language to identify a bladder pain component in women with Dysmenorrhoea-Related Pelvic Pain: A cross-sectional study

BACKGROUND

Dysmenorrhoea-Related Pelvic Pain (DRPP) is a common condition, which may or may not include bladder-related symptoms. Primary health care practitioners (PHCP) rely heavily on language for diagnosis of DRPP-related conditions. However, there are no established pain descriptors to assist PHCP to determine whether an individual's DRPP may include a bladder component.

AIMS

To identify differences in the use of pain descriptors in women with DRPP with and without a co-existing bladder pain component, through an exploratory study of the language of pelvic pain in women.

MATERIALS AND METHODS

A cross-sectional online survey of Australian and New Zealand women (n = 750, ages 18-49) who have self-identified pelvic pain. Free text and predetermined pain descriptors used by women with a self-perceived bladder pain component (DRPPB+, n = 468) were compared to those without bladder pain (DRPPB-, n = 282). Statistical analysis included Pearson χ2, logistic regression and analysis of variance tests using StataCorp Stata Statistical Software combined with qualitative data from AntConc concordance software.

RESULTS

Within free-form text, bloating (P = 0.014) and pressure (P = 0.031) were used more commonly to describe dysmenorrhoea in women with DRPPB+, while the word excruciating (P < 0.001) was more commonly used by women with DRPPB-. From a pre-determined list of descriptors, pounding (P < 0.001), tingling (P < 0.001), stabbing (P = 0.010), burning (P = 0.002) and cramping (P = 0.021) were more commonly used by women with DRPPB+, than women with DRPPB-.

CONCLUSIONS

Systematic patterns of word use should encourage practitioners to further enquire about bladder symptoms that may co-exist with dysmenorrhoea. Knowledge of these words may be useful in targeting diagnostic and therapeutic interventions.

Health Care Utilization by Patients With Chronic Pelvic Pain

OBJECTIVE

To describe the patterns of health care utilization among patients with chronic pelvic pain.

METHODS

Deidentified administrative claims data from the OptumLabs Data Warehouse were used. Adult female patients who had their first medical claim for chronic pelvic pain between January 1, 2016, and December 31, 2019, were included. Utilization was examined for 12 months after the index diagnosis. The greedy nearest neighbor matching method was used to identify a control group of individuals without chronic pelvic pain. Comparisons were made between those with and those without chronic pelvic pain using χ2 tests for categorical data and Wilcoxon rank-sum tests for continuous data.

RESULTS

In total, 18,400 patients were analyzed in the chronic pelvic pain cohort. Patients with chronic pelvic pain had a higher rate of chronic overlapping pain conditions. Patients with chronic pelvic pain had higher rates of health care utilization across all queried indices. They had more outpatient office visits; 55.5% had 10 or more office visits. Patients with chronic pelvic pain showed higher utilization of the emergency department (ED) (6.3 visits vs 1.9 visits; P<.001). Urine culture and pelvic ultrasonography were the most utilized tests. One-third of patients with chronic pelvic pain utilized physical therapy (PT), and 13% utilized psychological or behavioral therapy. Patients with chronic pelvic pain had higher rates of hysterectomy (8.9% vs 0.6%). The average total health care costs per patient with chronic pelvic pain per year was $12,254.

CONCLUSION

Patients with chronic pelvic pain have higher rates of chronic overlapping pain conditions and undergo more ED visits, imaging tests, and hysterectomies than patients without chronic pelvic pain. Improving access to multidisciplinary care, increasing utilization of interventions such as PT and psychological or behavioral therapy, and reducing ED utilization may be possible targets to help reduce overall health care costs and improve patient care.

Efficacy and classification of Sesamum indicum linn seeds with Rosa damascena mill oil in uncomplicated pelvic inflammatory disease using machine learning

Background and objectives: As microbes are developing resistance to antibiotics, natural, botanical drugs or traditional herbal medicine are presently being studied with an eye of great curiosity and hope. Hence, complementary and alternative treatments for uncomplicated pelvic inflammatory disease (uPID) are explored for their efficacy. Therefore, this study determined the therapeutic efficacy and safety of Sesamum indicum Linn seeds with Rosa damascena Mill Oil in uPID with standard control. Additionally, we analyzed the data with machine learning. Materials and methods: We included 60 participants in a double-blind, double-dummy, randomized standard-controlled study. Participants in the Sesame and Rose oil group (SR group) (n = 30) received 14 days course of black sesame powder (5 gm) mixed with rose oil (10 mL) per vaginum at bedtime once daily plus placebo capsules orally. The standard group (SC), received doxycycline 100 mg twice and metronidazole 400 mg thrice orally plus placebo per vaginum for the same duration. The primary outcome was a clinical cure at post-intervention for visual analogue scale (VAS) for lower abdominal pain (LAP), and McCormack pain scale (McPS) for abdominal-pelvic tenderness. The secondary outcome included white blood cells (WBC) cells in the vaginal wet mount test, safety profile, and health-related quality of life assessed by SF-12. In addition, we used AdaBoost (AB), Naïve Bayes (NB), and Decision Tree (DT) classifiers in this study to analyze the experimental data. Results: The clinical cure for LAP and McPS in the SR vs SC group was 82.85% vs 81.48% and 83.85% vs 81.60% on Day 15 respectively. On Day 15, pus cells less than 10 in the SR vs SC group were 86.6% vs 76.6% respectively. No adverse effects were reported in both groups. The improvement in total SF-12 score on Day 30 for the SR vs SC group was 82.79% vs 80.04% respectively. In addition, our Naive Bayes classifier based on the leave-one-out model achieved the maximum accuracy (68.30%) for the classification of both groups of uPID. Conclusion: We concluded that the SR group is cost-effective, safer, and efficacious for curing uPID. Proposed alternative treatment (test drug) could be a substitute of standard drug used for Female genital tract infections.

Cognitive Behavioral Therapy for Chronic Pelvic Pain: What Is It and Does It Work?

PURPOSE

Urologic chronic pelvic pain syndrome (UCPPS), which encompasses interstitial cystitis/bladder pain syndrome in women and men and chronic prostatitis/chronic pelvic pain syndrome in men, is a common, often disabling urological disorder that is neither well understood nor satisfactorily treated with medical treatments. The past 25 years have seen the development and validation of a number of behavioral pain treatments, of which cognitive behavioral therapy (CBT) is arguably the most effective. CBT combines strategies of behavior therapy, which teaches patients more effective ways of behaving, and cognitive therapy, which focuses on correcting faulty thinking patterns. As a skills-based treatment, CBT emphasizes "unlearning" maladaptive behaviors and thoughts, and replacing them with more adaptive ones that support symptom self-management.

MATERIALS AND METHODS

This review describes the rationale, technical procedures, and empirical basis of CBT.

RESULTS

While evidence supports CBT for treatment-refractory chronic pain disorders, there is limited understanding of why or how CBT might work, for whom it is most beneficial, or the specific UCPPS symptoms (eg, pain, urinary symptoms) it effectively targets. This is the focus of EPPIC (Easing Pelvic Pain Interventions Clinical Research Program), a landmark NIH trial examining the efficacy of low-intensity, home-based CBT for UCPPS relative to a nonspecific comparator featuring self-care recommendations of AUA guidelines.

CONCLUSIONS

Systematic efforts to increase both the efficiency of CBT and the way it is delivered (eg, home-based treatments) are critical to scaling up CBT, optimizing its therapeutic potential, and reducing the public health burden of UCPPS.

An Investigation of Associations between Pain Catastrophizing and Pain Disability in a Diverse Sample of Persons with Endometriosis

OBJECTIVE

This study sought to investigate associations between components of pain catastrophizing (using the Pain Catastrophizing Scale; rumination, magnification, and helplessness) and components of pain disability (using the Pain Disability Index; family/home responsibilities, recreation, social activity, occupation, sexual behaviour, self-care, life-support activity) in a diverse sample of persons with endometriosis.

METHODS

A total of 686 persons with a self-reported clinician-identified diagnosis of endometriosis participated in this study. Two-tailed independent samples t tests were used to examine between-group differences in pain disability and pain catastrophizing among those below and above clinically relevant moderate pain intensity levels. Between-group differences in pain disability among those below and above the clinically relevant pain catastrophizing level, and between-group differences in pain catastrophizing among those below and above the clinically relevant moderate pain disability level, were also analyzed.

RESULTS

Experiencing moderate or greater levels of pain intensity was associated with increased levels of pain disability and pain catastrophizing (P < 0.001). Strong associations between clinically relevant levels of pain catastrophizing and increased levels of pain disability (P < 0.001), in addition to between clinically relevant levels of moderate pain disability and increased levels of pain catastrophizing (P < 0.001), were found at both the total and subdomain levels.

CONCLUSION

Pain catastrophizing significantly affects pain disability and vice versa. Future research should examine the temporal relationship between catastrophizing and disability to inform intervention practices. Health care providers are strongly encouraged to evaluate the effects of endometriosis in patients using a biopsychosocial framework.

The role of psychosocial factors in the interprofessional management of women with chronic pelvic pain: A systematic review

INTRODUCTION

Chronic pelvic pain (CPP) is a common pain disorder in women associated with negative biopsychosocial consequences. The multifactorial etiology and maintaining aspects of CPP logically require an interprofessional treatment approach. However, the effects of interprofessional treatment strategies on psychosocial factors remain unclear. The study aims to investigate how interprofessional therapy helps to treat psychosocial factors in women with CPP. The systematic review summarizes the current evidence of interprofessional treatment in women with CPP.

MATERIAL AND METHODS

A systematic literature review was performed in six databases (Medline, Web of Science, Cochrane Library, PEDro, CINAHL, and PsycINFO) until February 2023. Studies were selected in a two-step approach applying as inclusion criteria the search combinations of Chronic Pelvic Pain and CPP, synonyms for interprofessional therapies, and for female patients. Studies were excluded if they were not quantitative primary research published in English, if CPP was not defined appropriately, if the study population was not female adult patients, if the interprofessional intervention was not operationalized appropriately, if they were single case studies, and if outcomes did not include at least one of the psychosocial factors pain, depressive symptoms, pain catastrophizing, fear, or anxiety. Risk of bias of the included studies was rated with the McMaster Critical Review Form. Studies were summarized narratively. The review is registered in PROSPERO (CRD42023391008).

RESULTS

Five studies with a total sample size of n = 186 women were included, three of them were uncontrolled retrospective before-after chart review. Only one study used a randomized controlled design, the other study used a non-randomized controlled group. The studies' methodological quality is adequate with perspective of study design. The multiprofessional treatment approaches used in the studies differed with regard to professions involved, therapy methods, and modalities. Psychosocial outcome measures were pain (five studies), depressive symptoms (three studies), and anxiety symptoms (four studies).

CONCLUSIONS

Although interprofessional treatment strategies for women with CPP are recommended in existing guidelines, available evidence is scarce and does not allow for identification of the best interprofessional treatment approach. The effect on psychosocial factors remains unclear. More research is needed determining the best practice interprofessional treatment option for women with CPP.

Endometriosis, chronic pain, anxiety, and depression: A retrospective study among 12 million women

BACKGROUND

There is a lack of information regarding the impact of the physical symptoms associated with endometriosis and chronic pain on the mental health and well-being of affected women. Thus, our study aimed to evaluate the relationship between endometriosis, chronic pain, anxiety, and depression.

OBJECTIVE

Our study aimed to evaluate the relationship between endometriosis, chronic pain, and mental health disorders among women registered in a large database until 2014.

STUDY DESIGN

This was a retrospective population-based study involving 12,904,324 hospitalized women from the Healthcare Cost and Utilization Project (HCUP) database between 2007 and 2014. We calculated the prevalence of chronic pain, endometriosis, anxiety, and depression during the study period. We used multivariate logistic regression to examine the relationship between these variables.

RESULTS

An upward pattern was noted in the prevalence of chronic pain, while an opposite trend was seen for endometriosis during the study period. After adjusting for sociodemographic characteristics and comorbidities, including depression, the highest odds ratio of experiencing anxiety appeared in the group with both chronic pain and endometriosis (OR = 2.719, 95 % CI 2.481-2.979).

LIMITATIONS

HCUP is a cross-sectional administrative database that does not link patients' records over the years. Thus, we could not establish any temporal association between endometriosis, chronic pain, anxiety, and depression.

CONCLUSION

Potential associations were identified between endometriosis, with and without chronic pain, anxiety, and depression. We recommended that clinicians provide proper medical management of endometriosis-related pain through symptom management and adequate counseling for those suffering from anxiety and depression.

Associations between endometriosis and common symptoms: findings from the Australian Longitudinal Study on Women's Health

BACKGROUND

Endometriosis has been linked to higher rates of a variety of symptoms; however, the findings from longitudinal studies are scarce and inconsistent.

OBJECTIVE

This study aimed to examine the association between endometriosis and common symptoms in a prospective cohort study.

STUDY DESIGN

This study included 7606 women born from 1973 to 1978 using data from the Australian Longitudinal Study on Women's Health that were collected every 3 years from 2009 to 2018. We identified women with endometriosis based on self-reported incidence from each survey and linked administrative health data. At each survey, women also completed a checklist on the presence of 24 symptoms. Generalized estimating equations for multinomial responses were used for analyses.

RESULTS

Women with endometriosis had significantly more menstrual symptoms than those without endometriosis with an adjusted odds ratio (95% confidence interval) of 3.61 (3.11-4.19) for severe period pain, 2.40 (2.10-2.74) for heavy menstrual bleeding, 1.76 (1.52-2.03) for irregular bleeding, and 1.52 (1.32-1.76) for premenstrual tension. They also had higher odds of mental health problems with adjusted odds ratios of 1.67 (1.39-2.01) for depression and 1.59 (1.24-2.03) for anxiety and higher odds of allergies and nonspecific symptoms with adjusted odds of 1.62 (1.40-1.89) for allergies or hay fever or sinusitis, 1.79 (1.56-2.05) for severe tiredness, 1.56 (1.35-1.81) for sleep difficulty, and 1.77 (1.37-2.18) for palpitations. There was also a strong association with other forms of pain with an adjusted odds ratio of 1.76 (1.53-2.04) for backpain, 1.50 (1.29-1.74) for headaches or migraines, and 1.65 (1.41-1.93) for stiff or painful joints. Women with endometriosis also had increased odds of developing bowel and urinary symptoms with an adjusted odds ratio (95% confidence interval) of 1.67 (1.35-2.08) for constipation, 1.46 (1.12-1.90) for hemorrhoids or piles, 1.25 (1.03-1.52) for indigestion or heartburn, 2.80 (1.71-4.58) for urine burn or stings, and 1.37 (1.03-1.82) for vaginal discharge or irritation. The association between each symptom and endometriosis was similar whether endometriosis was surgically confirmed or clinically suspected. No association was found between endometriosis and the risk for skin problems, leaking urine, or breathing difficulty.

CONCLUSION

This study suggests that women with endometriosis are more likely to report not only menstrual symptoms but are also at an increased risk for mental health problems, other pain symptoms, bowel and urinary symptoms, and nonspecific symptoms, such as severe tiredness and difficulty sleeping.

Preoperative quality of life at time of gynecologic surgery: considerations for postoperative management

BACKGROUND

Patients presenting for gynecologic surgery are a heterogeneous group. Preoperative quality of life may be a useful tool to guide postoperative management.

OBJECTIVE

This study aimed to examine the key drivers of preoperative quality of life to improve counseling and postoperative management.

STUDY DESIGN

This study analyzed preoperative survey results from 154 participants using the following surveys: National Institutes of Health Toolbox Global Health v1.2, Gastrointestinal: Gas and Bloating v1.1 13a, Gastrointestinal: Diarrhea v1.0 6a, and Sexual Function and Satisfaction Brief Profile (Female) v2.0, Perceived Stress Scale, the Vaginal Assessment Scale, and the Vulvar Assessment Scale. Survey results in the form of T-scores were compared in patients with endometrial cancer and patients with benign gynecologic conditions using the Kruskal-Wallis test. The multivariate analysis was performed using linear regression to adjust the comparisons for age, body mass index, and comorbidity.

RESULTS

Of the 154 patients, preoperative diagnosis was benign in 66% (n=102) and endometrial cancer in 34% (n=52). Patients with endometrial cancer were more likely to be older, non-White, in lower income brackets, have higher body mass index, and be postmenopausal (P<.05). Although preoperative global health scores were similar between benign and malignant cases (P>.05), when adjusted for age, the differences in global health quality of life between patients with benign gynecologic conditions and those with endometrial cancer became significant, because the endometrial cancer group was older than the benign group (P<.05). However, when adjusting for age, body mass index, and comorbidities (hypertension and diabetes), the differences were no longer significant (P>.05). Sexual interest was decreased in the patients with endometrial cancer both in the unadjusted and adjusted model; and vulvar complaints became significantly different between the groups when controlling for body mass index, age, and comorbidities (P<.05).

CONCLUSION

Despite substantial differences in preoperative diagnosis, preoperative quality of life is highly influenced by age, body mass index, and comorbidities. Therefore, these factors should be explored in surgical outcomes and postoperative management trials.

Incidence of self-reported pelvic pain and risk factors for pain 1 year after benign hysterectomy: A register study from the Swedish National Quality Registry for Gynecological Surgery

INTRODUCTION

The primary aim of this study was to determine the incidence of patient-reported pain 1 year after hysterectomy for benign gynecological conditions in relation to occurrence of preoperative pain. The secondary aim was to analyze clinical risk factors for pain 1 year after the hysterectomy in women with and without preoperatively reported pelvic/lower abdominal pain.

MATERIAL AND METHODS

This was a historical cohort study using data from the Swedish National Quality Registry for Gynecological Surgery on 16 694 benign hysterectomies. Data were analyzed using multivariable logistic regression models.

RESULTS

One year after surgery, 22.4% of women with preoperative pain reported pelvic pain and 7.8% reported de novo pelvic pain. For those with preoperative pain younger age (adjusted odds ratio [aOR] 1.75, 95% confidence interval [CI] 1.38-2.23 and aOR 1.21, 95% CI 1.10-1.34 for women aged <35 and 35-44 years, respectively), not being gainfully employed (aOR 1.43, 95% CI 1.26-1.63), pelvic pain as the main symptom leading to hysterectomy (aOR 1.51, 95% CI 1.19-1.90), endometriosis (aOR 1.18, 95% CI 1.06-1.31), and laparoscopic hysterectomy (aOR 1.30, 95% CI 1.07-1.58), were clinically relevant independent risk factors for pelvic/lower abdominal pain 1 year after surgery, as were postoperative complications within 8 weeks after discharge. Meanwhile, clinically relevant independent risk factors for reporting de novo pain 1 year after surgery were younger age (aOR 2.05, 95% CI 1.08-3.86 and aOR 1.29, 95% CI 1.04-1.60 for women aged <35 and 35-44 years, respectively), and postoperative complications within 8 weeks after discharge.

CONCLUSIONS

The incidence of pelvic pain and de novo pain 1 year after hysterectomy was relatively high. Women with and without reported preoperative pelvic/lower abdominal pain represented clinically different populations. The risk factors for pelvic pain seemed to differ in these two populations. The differences in risk factors could be taken into consideration in the preoperative counseling and in the decision-making concerning method of hysterectomy, provided that large well-designed studies confirm these risk factors.

Health literacy in women with chronic pelvic pain

INTRODUCTION AND HYPOTHESIS

Limited health literacy (HL) is a risk factor for poor patient outcomes, including pain. Chronic pelvic pain (CPP) is a prevalent disorder affecting up to 25% of women and coexists with multiple overlapping conditions. This study aimed to describe health literacy in women with CPP, primarily correlate HL to pain intensity and pain duration, and secondarily correlate HL to mood symptoms and pain catastrophizing. We hypothesized that women with CPP with higher HL would report lower levels of pain intensity and duration.

METHODS

This was a prospective, cross-sectional study. Forty-five women with CPP were recruited from outpatient Physical Medicine & Rehabilitation and Female Pelvic Medicine & Reconstructive Surgery clinics. Validated questionnaires were administered to evaluate pain intensity and duration, pain disability, psychological symptoms, pain catastrophizing, and health literacy. Statistical analyses included descriptive statistics of patient characteristics and summary scores, as well as Spearman's rank correlation coefficients (rho) to assess the strength of associations between summary scores and health literacy.

RESULTS

Forty-five women with CPP were enrolled with mean age of 49 years, majority non-Hispanic White, and median chronic pelvic pain duration of 7 years. Possible or high likelihood of limited health literacy was identified in 20% women with CPP (11.1% and 8.9%, respectively). Limited health literacy was moderately correlated with pain intensity, depressive symptoms, and pain catastrophizing. Pain duration was not significantly correlated with health literacy. The remaining 80% of women with CPP were likely to have adequate health literacy.

CONCLUSIONS

A majority of women with CPP in this single center study were likely to have adequate health literacy. Limited health literacy was seen in a minority of women with CPP but was moderately correlated with greater pain intensity, more depressive symptoms, and higher pain catastrophizing. This study identified that women with CPP were likely to have adequate HL, but underscores the importance of considering HL screening and interventions in those with higher pain intensity, depression, and pain catastrophizing.

Trends in chronic pain conditions among delivering women with and without mood and anxiety disorders

OBJECTIVE

The co-existence of chronic pain conditions with anxiety and/or depression is common in the general population but poorly described during pregnancy. In this study, we sought to describe trends in chronic pain among a sample of delivering people and describe the co-existence of chronic pain with anxiety and/or depression among delivering people.

METHODS

This cross-sectional study used data from Optum's de-identified Clinformatics® Data Mart Database between 2008 and 2021, for delivering persons with coverage by single employer-based health plan. We computed predicted margins from generalized estimating equations to determine the marginal predicted probability of chronic pain among all delivering and non-delivering persons who identify as women with and without diagnosed anxiety and/or depression.

RESULTS

Musculoskeletal and pelvic pain occurred most often regardless of delivering status. Delivering persons with anxiety and/or depression had higher marginal predicted probabilities of chronic pain compared to all delivering persons. Between 2008 and 2021, the predicted probabilities ranged from 0.400 to 0.527 and 0.221-0.261, respectively.

CONCLUSION

Chronic pain conditions are common in pregnancy and nearly two times higher among individuals with anxiety and/or depression. The frequency of comorbid depression and/or anxiety with pain disorders among delivering persons highlights the importance of proper detection, coordination of care, and safe treatment options for this population.

Evaluation and Medical Management of Chronic Pelvic Pain

Chronic pelvic pain (CPP) is a challenging condition affecting an estimated 15% of females in the United States. Multiorgan system dysfunction results in the complex clinical pain presentation. Similar to other chronic pain syndromes, CPP is influenced by biopsychosocial factors and requires a multimodal approach for optimal pain management. This review summarizes the clinical evaluation and medical management of CPP with a comprehensive approach.

The temporal effect of emotional distress on psychological and physical functioning in endometriosis: A 12-month prospective study

Psychological factors of emotional distress and cognition have an important role in the understanding and management of endometriosis; however, their temporal relationship with key pain variables is not fully understood. This exploratory study sought to establish the temporal relationship between psychological and pain-related factors in a 12-month prospective study of 208 Australian women with endometriosis. Participants, aged 18-50 years and living in Australia, were recruited via social media and completed baseline (May 2019) and 12-month follow-up (June 2020) surveys. Participants who reported a diagnosis of endometriosis and menses in the past 12 months were included in the study. Structural equation modelling was used to determine the temporal effects of psychological and pain-related factors in endometriosis. In a covariate-adjusted model, baseline emotional distress was the only variable to predict pain catastrophizing (β = .24, p < .01), functional pain disability (β = .16, p < .05) and concomitant emotional distress (β = .55, p < .001) 12 months later, adjusting for age and chronic illness. Women who exhibit symptoms of distress may be at risk of poorer psychological and physical function at 12 months. Further research is required to understand the impact of psychological management early in the disease course.

Sacral neuromodulation in the management of chronic pelvic pain: A systematic review and meta-analysis

INTRODUCTION

Sacral neuromodulation (SNM) is a treatment approved for use in several conditions including refractory overactive bladder (OAB) and voiding dysfunction. Chronic pelvic pain (CPP) is a debilitating condition for which treatment is often challenging. SNM shows promising effect in patients with refractory CPP. However, there is a lack of clear evidence, especially in long-term outcomes. This systematic review will assess outcomes of SNM for treating CPP.

METHODS

A systematic search of MEDLINE, Embase, Cochrane Central and clinical trial databases was completed from database inception until January 14, 2022. Studies using original data investigating SNM in an adult population with CPP which recorded pre and posttreatment pain scores were selected. Primary outcome was numerical change in pain score. Secondary outcomes were quality of life assessment and change in medication use and all-time complications of SNM. Risk of bias was assessed using the Newcastle Ottawa Tool for cohort studies.

RESULTS

Twenty-six of 1026 identified articles were selected evaluating 853 patients with CPP. The implantation rate after test-phase success was 64.3%. Significant improvement of pain scores was reported in 13 studies; three studies reported no significant change. WMD in pain scores on a 10-point scale was -4.64 (95% confidence interval [CI] = -5.32 to -3.95, p < 0.00001) across 20 studies which were quantitatively synthesized: effects were maintained at long-term follow-up. Mean follow-up was 42.5 months (0-59). Quality of life was measured by RAND SF-36 and EQ-5D questionnaires and all studies reported improvement in quality of life. One hundred and eighty-nine complications were reported in 1555 patients (Clavien-Dindo Grade I-IIIb). Risk of bias ranged from low to high risk. Studies were case series and bias stemmed from selection bias and loss to follow-up.

CONCLUSION

Sacral Neuromodulation is a reasonably effective treatment of Chronic Pelvic Pain and significantly reduces pain and increases patients' quality of life with immediate to long-term effects.

Beliefs and Narratives Associated with the Treatment of Chronic Pelvic Pain in Women

STUDY OBJECTIVE

Female patients with chronic pelvic pain (CPP) face complicated healthcare journeys, but narrative perspectives on CPP treatment are lacking.

DESIGN

We collected data in English and Spanish from discussion groups and individual interviews with stakeholders around female CPP.

SETTING

A tertiary care center for gynecologic care.

PATIENTS

Patients with CPP who self-identified as women/female, community healthcare workers, and providers who care for women with CPP.

INTERVENTIONS

We conducted discussion groups with all 3 types of stakeholders and individual interviews with female patients who have CPP.

MEASUREMENTS AND MAIN RESULTS

Patient participants completed condition specific validated questionnaires. De-identified transcripts were coded with NVivo software. We contrasted patient characteristics and codes between patients with CPP who did and did not report opioid use in the last 90 days. The mean pain score of patient participants was 6/10 ± 2/10, and 14 of 47 (28%) reported recent opioid use, without significant differences between patients with and without recent opioid use. Thematic saturation was achieved. Five main themes emerged: the debilitating nature of CPP, emotional impacts of CPP, challenges in CPP healthcare interactions, treatment for CPP, and the value of not feeling alone. Common threads voiced by stakeholders included difficulty discussing chronic pain with others, a sense of inertia in treatment, interest in alternative and less invasive treatments before more involved treatments, and the need for individualized, stepwise, integrated treatment plans. Participants agreed that opioids should be used when other treatments fail, but women recently using opioids voiced fewer concerns about addiction and positive experiences with opioid efficacy.

CONCLUSIONS

These findings among female patients with CPP and also among community healthcare workers and providers advocate for a move toward patient-centered care, particularly the acknowledgment that every woman experiences pain in a singular way. Furthermore, stakeholders voice a deep need for development of individualized treatment plans.

Incidence of Chronic Pelvic Pain in Females Attending a Gynaecology Outpatient Department

Background and Aims: Chronic pelvic pain (CPP) is a persistent pelvic pain that leads to reduced work performance and impaired quality of life in females. Nearly 15% of females report time off from paid work and around 45% report reduced work productivity. There is a paucity of studies to address the issue, especially with a multidisciplinary and multifactorial view. Various gynaecological disorders are associated with CPP such as endometriosis, adenomyosis, adhesions, chronic pelvic inflammatory disease, and pelvic congestion syndrome. The objective is to determine the frequency of CPP in females attending gynaecologic outpatient departments. Materials and Methods: A total of 201 patients aged 14–48 years attending the gynaecologic outpatient department for gynaecological disorders with complaints of lower abdominal pain were included in this study. Patients enrolled in the study were assessed by a detailed history and pelvic examination, and a structured questionnaire was filled out. Data were analysed using the statistical package for social sciences version 23.0 (International Business Machines Corporation, Armonk, New York, USA). Results: The mean age of the patients was 32.39±6.98 years. The frequency of CPP in females was observed as 95.52% (95% confidence interval: 91.67–97.93%) The rate of CPP was significantly high in females with parity ≤5 and those who had a duration of pain lower than 36 months. In multivariate analysis, adjusted odds ratio by stepwise logistic regression model showed that parity (parity 0–1) and duration of pain (≤36 months) were significantly associated with CPP in females. Conclusion: The study indicates that the most common gynaecological causes of CPP in females attending the outpatient department were those with endometriosis followed by adenomyosis. The management of CPP needs patient-centred care with a multidisciplinary approach. This will lead to early and effective management.

Hemodynamic and neurobiological factors for the development of chronic pelvic pain in patients with pelvic venous disorder

OBJECTIVE

The study was aimed at the identification of hemodynamic and neurobiological factors for the development of chronic pelvic pain (CPP) in patients with pelvic venous disorder (PeVD) using ultrasound, radionuclide, and enzyme immunoassay methods.

METHODS

This cohort study included 110 consecutive patients with PeVD and 20 healthy controls. Seventy patients with PeVD had symptoms (CPP in 100% of cases, discomfort in hypogastrium, dyspareunia, vulvar varices, and dysuria), and 40 were asymptomatic. Patients underwent clinical examination, duplex ultrasound study of the pelvic veins and lower extremities, and single-photon emission computed tomography of the pelvic veins with in vivo labeled red blood cells. The prevalence, duration, severity, and pattern of reflux in the pelvic veins, as well as the severity of pelvic venous congestion, were evaluated. Healthy controls underwent only clinical and duplex ultrasound examination. All 130 patients were assessed using enzyme immunoassays to determine plasma levels of calcitonin gene-related peptide (CGRP) and substance P (SP).

RESULTS

Symptomatic patients with PeVD had a higher prevalence of reflux in the ovarian veins (OVs) than asymptomatic ones (45.7% vs 10%, respectively; P = .001) and a greater reflux duration (4.1 ± 1.7 seconds vs 1.4 ± 0.3 seconds; P = .002), although no differences in the OV diameter were found. Similar results were obtained when comparing the diameters of the parametrial veins (PVs) and the duration of reflux in them. Type II/III reflux (greater than 2 seconds) was identified in 41.4% of symptomatic and in only 5% of asymptomatic patients (P = .001). Among patients with CPP, 24.2% had a combined reflux in the OVs, PVs, and uterine veins, and 45.7% had a combined reflux in the OVs and PVs, whereas 90% of patients without CPP had only an isolated reflux in the PVs. The pelvic venous congestion was moderate or severe in 95.7% of patients with CPP and in only 15% patients without CPP (P = .001). In patients with PeVD, the presence of CPP was associated with higher levels of CGRP and SP compared with asymptomatic patients (CGRP: 0.48 ± 0.06 vs 0.19 ± 0.02 ng/mL, respectively, P = .001; SP: 0.38 ± 0.08 vs 0.13 ± 0.03 ng/mL, P = .001).

CONCLUSIONS

In patients with PeVD, significant hemodynamic and neurobiological factors for the CPP development were found to be reflux in the pelvic veins greater than 2 seconds, involvement of several venous collectors, and increased plasma levels of CGRP and SP.

Chronic Pelvic Pain Profiles in Women Seeking Care in a Tertiary Pelvic Pain Clinic

OBJECTIVE

Female chronic pelvic pain (CPP) has multiple pain generators and significant psychosocial sequalae. Biopsychosocial-based phenotyping could help identify clinical heterogeneity that may inform tailored patient treatment. This study sought to identify distinct CPP profiles based on routinely collected clinical information and evaluate the validity of the profiles through associations with social histories and subsequent health care utilization.

METHODS

Women (18-77 years, n = 200) seeking care for CPP in a tertiary gynecological pelvic pain clinic between 2017 and 2020 were included. Baseline data of pain intensity, interference, catastrophizing, acceptance, overlapping pelvic pain syndromes, and co-occurring psychiatric disorders were subject to a partition around medoids clustering to identify patient profiles. Profiles were compared across social history and subsequent treatment modality, prescribed medications, and surgeries performed.

RESULTS

Two profiles with equal proportion were identified. Profile 1 was vulvodynia and myofascial pelvic pain-dominant characterized by lower pain burden and better psychological functioning. Profile 2 was visceral pain-dominant featuring higher pain interference and catastrophizing, lower pain acceptance, and higher psychiatric comorbidity. Patients in Profile 2 had 2-4 times higher prevalence of childhood and adulthood abuse history (all P < .001), were more likely to subsequently receive behavioral therapy (46% vs 27%, P = .005) and hormonal treatments (34% vs 21%, P = .04), and were prescribed more classes of medications for pain management (P = .045) compared to patients in Profile 1.

CONCLUSIONS

Treatment-seeking women with CPP could be separated into two groups distinguished by pain clusters, pain burden, pain distress and coping, and co-occurring mental health disorders.

Effect of high-frequency repetitive transcranial magnetic stimulation under different intensities upon rehabilitation of chronic pelvic pain syndrome: protocol for a randomized controlled trial

INTRODUCTION

Nearly one in seven women worldwide suffers from chronic pelvic pain syndrome (CPPS) each year. Often, CPPS necessitates a combination of treatments. Studies have shown the good therapeutic effects of repetitive transcranial magnetic stimulation (rTMS) upon CPPS. We wish to undertake a randomized controlled trial (RCT) to observe the effect of high-frequency rTMS at different intensities upon CPPS.

METHODS AND ANALYSES

In this prospective, double-blinded RCT, 63 female CPPS participants will be recruited and randomized (1:1:1) to high-intensity rTMS, low-intensity rTMS, or sham rTMS. The control group will receive a 10-day course of conventional pelvic floor (PF) rehabilitation (neuromuscular stimulation, magnetic therapy, or light therapy of the PF). On the basis of conventional treatment, participants in the high-intensity rTMS group will receive pulses of 10 Hz with a resting motor threshold (RMT) of 110% for a total of 15,000 pulses. Participants in the low-intensity rTMS group will receive pulses of 10 Hz with an RMT of 80% with 15,000 pulses. The sham rTMS group will be subjected to sham stimulation with the same sound as produced by the real magnetic stimulation coil. The primary outcome will be determined using a visual analog scale, the Genitourinary Pain Index, Zung Self-Rating Anxiety Scale, and Zung Self-Rating Depression Scale. The secondary outcome will be determined by electromyography of the surface of PF muscles at baseline and after treatment completion.

ETHICS AND DISSEMINATION

This study is approved by the Ethics Committee of Bao'an People's Hospital, Shenzhen, Guangdong Province (approval number: BYL20211203). The results will be submitted for publication in peer-reviewed journals and disseminated at scientific conferences (Protocol version 1.0-20220709).

Dysmenorrhea catastrophizing and functional impairment in female pelvic pain

Background

Dysmenorrhea is suggested to increase the risk of chronic pain by enhancing central sensitization. However, little is known about whether emotional and cognitive responses induced by dysmenorrhea contribute to chronic pain interference. This study examined the association between catastrophizing specific to dysmenorrhea and both dysmenorrhea and chronic pelvic pain (CPP)-associated pain interference.

Methods

Women (N = 104) receiving care for CPP through a tertiary gynecological pain clinic between 2017 and 2020 were recruited. They completed the Pain Catastrophizing Scale, the Brief Pain Inventory-pain interference, and a separate questionnaire regarding dysmenorrhea symptoms and treatment preceding the development of CPP. Dysmenorrhea catastrophizing and interference measures were developed and tested for internal consistency and construct validity. Multiple linear regression models examined dysmenorrhea catastrophizing in association with dysmenorrhea interference and CPP-associated pain interference.

Results

Dysmenorrhea catastrophizing and interference measures demonstrated excellent internal consistency (Cronbach's Alpha = 0.93 and 0.92 respectively) and evidence of construct validity (correlated with dysmenorrhea severity and treatment, Ps < 0.01). Dysmenorrhea catastrophizing was moderately correlated with pain catastrophizing (ρ = 0.30, P = 0.003), and was associated with greater dysmenorrhea interference (P < 0.001) and CPP-associated pain interference (P = 0.032) accounting for general pain catastrophizing and other outcome-specific confounders. Dysmenorrhea intensity was most predictive of dysmenorrhea catastrophizing.

Conclusion

Among our clinical sample of women with CPP, dysmenorrhea catastrophizing was associated with greater dysmenorrhea interference and subsequent CPP-associated pain interference. More research is needed to determine whether reduction in dysmenorrhea catastrophizing leads to reduced pain interference associated with female pelvic pain.

The role of catastrophizing in chronic cyclical pelvic pain: A systematic review and meta-analysis

BACKGROUND

Dysmenorrhea (painful menstrual cramps) is one of the most common gynecological complaints in women and girls. Dysmenorrhea may be a condition itself or a result of another medical condition, including endometriosis and chronic pelvic pain. Research examining the relationship between menstrual pain ratings and catastrophizing has produced mixed results.

OBJECTIVE

To review and meta-analyze the relationship between catastrophizing and pain ratings of chronic cyclical pelvic pain.

DESIGN

Cross-sectional, longitudinal, and intervention studies that reported the relationship between menstrual/pelvic pain and catastrophizing were included. Study populations had to include healthy menstruating persons or persons with a condition associated with cyclical pelvic pain including primary dysmenorrhea, endometriosis, and/or chronic pelvic pain.

DATA SOURCES AND METHODS

A systematic search of articles published since 2012 on PubMed, PsychInfo, CINHAL, and Medline was conducted in January and rerun in November of 2022. Search terms included cyclical pelvic pain, dysmenorrhea, endometriosis, pelvic pain, and catastrophizing. Data extraction was completed independently by two extractors and cross-checked for errors. A random-effects meta-regression was used to synthesize the data using restricted maximum likelihood.

RESULTS

Twenty-five studies examining 4,540 participants were included. A random effects model found a meta-correlation between catastrophizing and pain of r = .31 (95% confidence interval: .23-.40) p < .001. Heterogeneity was large and significant (I2 = 84.5%, Q(24) = 155.16, p < .001). Studies that measured general pelvic pain rather than cyclical pelvic pain specifically and those that used multi-item rather than single-item measures of pain had significantly higher correlations. Age and depression did not moderate the relationship between catastrophizing and pain.

CONCLUSION

A systematic review and meta-analysis found that catastrophizing had a small but significant positive association with pain ratings. Patients experiencing cyclical pelvic pain may benefit from interventions targeting the psychological management of pain.

Nurses' role in the management of persons with chronic urogenital pelvic pain syndromes: A scoping review

BACKGROUND

Pelvic pain has cognitive, behavioral, sexual, and emotional consequences. Nurses involved in pelvic floor rehabilitation clinics have contacts with patients reporting chronic pain and should know the most appropriate service for patient referral, to submit the problem to professionals capable of correctly assessing and managing the condition. Furthermore, in some countries nurses can use conservative methods to treat the painful symptoms inside a multidisciplinary team such as breathing retraining, biofeedback, and noninvasive neuromodulation. This paper aims to provide an overview of the literature regarding the role of rehabilitation nurses in dealing with patients suffering from chronic urogenital pelvic pain or urogenital painful syndromes, inside a multidisciplinary team.

METHODS

Scoping review on Pubmed, CINAHL, Embase, Scopus, Web of Science including trials, reviews, case studies or series, and other descriptive studies regarding the role of nurses inside the multidisciplinary team in the management of males and females presenting chronic pelvic pain (CPP) or chronic pelvic pain syndrome (CPPS).

RESULTS

The 36 papers included in this review allowed answering research questions in four areas of nursing: collecting basic information, referring the person to appropriate services, evidence-based nursing interventions for CPP and CPPS, and proper documentation. Clinical history and assessment of breathing pattern, Muscular assessment and research of trigger points are the main points of data collection. Techniques for muscular relaxation and breathing retraining are important aspects of treatment, as well as biofeedback and noninvasive neuromodulation where the law allows nurses to practice such techniques. The McGill pain questionnaire and the pain inventory of the International Pain Society allow systematic data collection and handover.

CONCLUSION

Rehabilitation nurses work inside multidisciplinary teams when dealing with persons suffering from pelvic pain; further research is needed as our comprehension of the underlying pathophysiological mechanisms of CPP and CPPS evolve.

Non-pharmacological therapies for treating chronic pelvic pain in women: A review

Chronic pelvic pain (CPP) is an intricate condition with multiple etiologies that lead to indefinite pain mechanisms. Physicians and researchers are challenged in its treatment, and the combined therapy of pharmacologic and non-pharmacologic treatment has been recognized as a multidisciplinary approach cited by guidelines and adopted in clinical practice. As an alternative therapy for CPP, non-pharmacologic therapies benefit patients and deserve further study. This study reviews the literature published from January 1991 to April 2022 on non-pharmacologic therapies for CPP in adult women. Based on a survey, this review found that the most commonly used non-pharmacological therapies for CPP include pelvic floor physical therapy, psychotherapy, acupuncture, neuromodulation, and dietary therapy. By evaluating the efficacy and safety of each therapy, this study concluded that non-pharmacological therapies should be included in the initial treatment plan because of their high degree of safety and low rate of side effects. To fill the lack of data on non-pharmacologic therapies for CPP, this study provides evidence that may guide treatment and pain management.

Does group physiotherapy improve pain scores and reduce the impact of pelvic pain for women referred with persistent pelvic pain? A clinical trial

Introduction:

This study aimed to test group Physiotherapy sessions – pain education and supervised exercise − in addition to individual consultations, for women referred with persistent pelvic pain (with/without endometriosis), with the primary outcomes being pain scores and pain impact.

Methods:

Parallel study design with three treatment arms: (1) usual care: a suite of individual Physiotherapy consultations; (2) introductory group pain education session followed by usual care and (3) introductory group pain education session followed by usual care and an 8-week supervised group exercise programme.

Results:

Ninety women were recruited (30/treatment arm), with 66 women (73%) completing their allocated treatment. Participants were aged between 16 and 51 years; endometriosis was confirmed in 41% ( n = 27/66) of the study population. Data was analysed using descriptive and inferential statistics. Statistically significant gains ( p < 0.05) in pain scores and pelvic pain impact scores were observed in all arms. Between groups, there was statistically significant improvement ( p < 0.05) in pelvic pain impact score for those who attended the group pain education session followed by usual care (arm 2), compared to usual care (arm 1) alone. There was no significant added improvement with the weekly supervised group exercise programme (arm 3), when compared to those who received the group pain education programme and usual care (arm 2).

Conclusion:

This study has demonstrated positive benefits of a group pain education session on pain scores and pelvic pain impact for women referred with persistent pelvic pain, when added as a precursor to individual Physiotherapy consultations.

Persistent Pelvic Pain in Patients With Endometriosis

As our understanding of chronic pain conditions, including endometriosis-related pain and chronic pelvic pain evolves, the evaluation and management of patients should reflect our increasing appreciation of the role of central sensitization, comorbid conditions and biopsychosocial factors on the pain experience and treatment outcomes. This review provides a systematic approach to persistent pain in patients with endometriosis. Expanding the evaluation and treatment of endometriosis-related pain by all health care providers could limit unnecessary surgical interventions and best meet our patient's needs.

Psychological Profile in Women with Chronic Pelvic Pain

(1) Background: Chronic Pelvic Pain (CPP) is a prevalent medical condition with a complex treatment due to different variables that influence its clinical course. (2) Methods: Psychological variables such as depression, anxiety, catastrophizing or neuroticism have been described as influencing CPP. This is a cross-sectional study of 63 patients with CPP sent for a psychological evaluation due to participation in group therapy for CPP. The main purpose of this study was to characterize the baseline psychological characteristics of women with CPP. The NEO Five Factor Inventory (NEO-FFI), State and Trait Anxiety Inventory (STAI), Beck Depression Inventory-Fast Screen (BDI-FS), Pain Catastrophizing Scale (PCS) and Chronic Pain Acceptance Questionnaire (CPAQ) were performed. (3) Results: The personality profile of patients (NEO FFI) shows high neuroticism, low extraversion and low conscientiousness. The 25.4% of patients had moderate or severe depression according to BDI-FS results, almost half of the patients had high levels of anxiety trait (>P75, 49.2%) and more than half the patients had high levels of anxiety state (>P75, 59.5%). Punctuations of PCS and CPAQ are similar to patients with fibromyalgia. (4) Conclusions: CPP is associated with high levels of depression, anxiety, neuroticism, catastrophizing and low pain acceptance. It is important to develop interventions that can modify these psychological factors in order to improve the clinical course of CPP.

Prevalence of chronic pelvic pain and primary dysmenorrhea in women of reproductive age in Ecuador

Background

Chronic pelvic pain (CPP) and primary dysmenorrhoea are debilitating conditions that can impair the quality of life of affected women. These conditions are frequently neglected, delaying proper diagnosis and healthcare provision. This study aimed to estimate the prevalence of CPP and primary dysmenorrhoea in Ecuador and identify potential variables associated with their occurrence.

Methods

We conducted a cross-sectional survey in an urban neighbourhood of Quito, the capital of Ecuador. A total of 2397 participants of 14–49 years of age were included. The data were collected through questionnaires administered by trained interviewers.The crude and adjusted prevalence ratios were calculated using a log-binomial regression model. The correlation between pain intensity catastrophising of symptoms were statistically analysed.

Results

The prevalence of CPP and primary dysmenorrhoea was 9.8% and 8.9%, respectively. Irritative urinary symptoms, primary dysmenorrhoea, and underlying mental disorders were associated with CPP, while smoking, irritable bowel syndrome, sleep disturbance, dyspareunia, and mental disorders were associated with primary dysmenorrhoea.

Conclusions

The prevalence of CPP and primary dysmenorrhoea in Ecuador was similar to that in other Latin American countries. Primary dysmenorrhoea is a risk factor of CPP, and less than a quarter of women are undergoing treatment for the condition. Our findings reinforce the importance of healthcare interventions in anticipating the diagnosis of these conditions in women of reproductive age.

Childhood betrayal trauma, dissociation, and shame impact health-related quality of life among individuals with chronic pelvic pain

BACKGROUND

High betrayal trauma (HBT), or interpersonal trauma perpetrated by someone close, is linked to dissociation and shame, while trauma perpetrated by someone less close, low betrayal trauma (LBT) is associated with post-traumatic stress disorder (PTSD).

OBJECTIVE

Child interpersonal trauma is common among women with chronic pelvic pain (CPP) and can negatively impact physical and mental health-related quality of life (HRQOL). Our study investigates unexplored connections between these variables.

PARTICIPANTS & SETTING

Survey data were analyzed from 96 English-speaking female patients with CPP at a women's health clinic (mean age = 33, 59 % White non-Hispanic, 62 % married or cohabitating, 61.5 % completed post-high school degree); prevalence of HBT and LBT were 65.2 % and 45.6 %, respectively.

METHODS

Multiple regression analyzed relationships between mental and physical HRQOL and dissociation, shame, and PTSD. Parallel mediation analyses examined indirect relationships between mental and physical HRQOL and exposure to childhood HBT and LBT.

RESULTS

Dissociation was related to worse physical HRQOL, while shame was related to worse physical and mental HRQOL. Dissociation and shame mediated relationships between childhood HBT and current mental (R² = 0.08, p = .01) and physical (R² = 0.11, p = .002) HRQOL. Shame, but not PTSD, mediated relationships between childhood LBT and current mental (R² = 0.14, p < .001) and physical (R² = 0.16, p < .001) HRQOL.

CONCLUSIONS

Our study provides preliminary evidence that dissociation and shame negatively impact HRQOL among individuals with CPP in the context of exposure to different types of childhood betrayal trauma. Replication studies to validate our results with larger samples and longitudinal designs are encouraged.

Study protocol and methods for Easing Pelvic Pain Interventions Clinical Research Program (EPPIC): a randomized clinical trial of brief, low-intensity, transdiagnostic cognitive behavioral therapy vs education/support for urologic chronic pelvic pain syndrome (UCPPS)

Background

Urologic chronic pelvic pain syndrome (UCPPS) encompasses several common, costly, diagnoses including interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome that are poorly understood and inadequately treated with conventional medical therapies. Behavioral strategies, recommended as a first-line treatment for managing symptoms, are largely inaccessible, time and labor intensive, and technically complex. The Easing Pelvic Pain Interventions Clinical Research Program (EPPIC) is a clinical trial examining the efficacy of low-intensity cognitive behavioral therapy (Minimal Contact CBT or MC-CBT) for UCPPS and its durability 3 and 6 months post treatment. Additional aims include characterizing the operative processes (e.g., cognitive distancing, context sensitivity, coping flexibility, repetitive negative thought) that drive MC-CBT-induced symptom relief and pre-treatment patient variables that moderate differential response.

Methods

UCPPS patients (240) ages 18–70 years, any gender, ethnicity, and race, will be randomized to 4-session MC-CBT or a credible, non-specific education comparator (EDU) that controls for the generic effects from simply going to treatment. Efficacy assessments will be administered at pre-treatment, 2 weeks, and 3 and 6 months post treatment-week acute phase. A novel statistical approach applied to micro-analytic mediator assessment schedule will permit the specification of the most effective CBT component(s) that drive symptom relief.

Discussion

Empirical validation of a low-intensity self-management therapy transdiagnostic in scope has the potential to improve the health of chronic pelvic pain patients refractory to medical therapies, reduce social and economic costs, conserve health care resources, as well as inform evidence-based practice guidelines. Identification of change mechanisms and moderators of treatment effects can provide proactive patient-treatment matching fundamental to goals of personalized medicine.

Analgesic Alkaloids Derived From Traditional Chinese Medicine in Pain Management

Chronic pain is one of the most prevalent health problems. The establishment of chronic pain is complex. Current medication for chronic pain mainly dependent on anticonvulsants, tricyclic antidepressants and opioidergic drugs. However, they have limited therapeutic efficacy, and some even with severe side effects. We turned our interest into alkaloids separated from traditional Chinese medicine (TCM), that usually act on multiple drug targets. In this article, we introduced the best-studied analgesic alkaloids derived from TCM, including tetrahydropalmatine, aloperine, oxysophocarpine, matrine, sinomenine, ligustrazine, evodiamine, brucine, tetrandrine, Stopholidine, and lappaconitine, focusing on their mechanisms and potential clinical applications. To better describe the mechanism of these alkaloids, we adopted the concept of drug-cloud (dCloud) theory. dCloud illustrated the full therapeutic spectrum of multitarget analgesics with two dimensions, which are “direct efficacy”, including inhibition of ion channels, activating γ-Aminobutyric Acid/opioid receptors, to suppress pain signal directly; and “background efficacy”, including reducing neuronal inflammation/oxidative stress, inhibition of glial cell activation, restoring the balance between excitatory and inhibitory neurotransmission, to cure the root causes of chronic pain. Empirical evidence showed drug combination is beneficial to 30–50% chronic pain patients. To promote the discovery of effective analgesic combinations, we introduced an ancient Chinese therapeutic regimen that combines herbal drugs with “Jun”, “Chen”, “Zuo”, and “Shi” properties. In dCloud, “Jun” drug acts directly on the major symptom of the disease; “Chen” drug generates major background effects; “Zuo” drug has salutary and supportive functions; and “Shi” drug facilitates drug delivery to the targeted tissue. Subsequently, using this concept, we interpreted the therapeutic effect of established analgesic compositions containing TCM derived analgesic alkaloids, which may contribute to the establishment of an alternative drug discovery model.

Effect of sex education on sexual function and sexual quality of life in women with endometriosis: A quasi-experimental study

OBJECTIVE

To evaluate the effect of a sex education program on sexual function and sexual quality of life in women with endometriosis.

METHODS

In a quasi-experimental study, women with endometriosis who had undergone laparoscopic surgery were assigned to an intervention group (n = 36) or a control group (n = 36). The intervention group received a sex education program consisting of two sessions a week (90 min each) for two consecutive weeks; the control group received none. Both groups were followed for 12 weeks. Sexual function and sexual quality of life were assessed on the Female Sexual Function Index (FSFI) and the Sexual Quality of life-Female (SQOL-F) questionnaire before the intervention, as well as 8 and 12 weeks after the intervention. Outcomes were analyzed using Student t test, the χ² test, Fisher exact test, and repeated measures analysis of variance.

RESULTS

The mean age of the study participants was 36.9 ± 5.7 years. The two groups did not differ significantly in terms of demographics and pre-intervention clinical characteristics. At the end of the study, sex education reduced female sexual dysfunction by 58.1% in the intervention group. The mean FSFI score increased significantly in the intervention group from pre-intervention to 8 and 12 weeks post-intervention compared with the scores in the control group (P < 0.001).

CONCLUSIONS

Sex education appears to be a promising intervention for reducing sexual dysfunction and improving sexual function and sexual quality of life in women with endometriosis. Future studies should encompass longer periods of follow up to obtain further data on the efficacy of sex education in this setting.

Potential Feasibility of an Online Hypnosis Intervention for Women with Persistent Pelvic Pain

This study aimed to examine the potential feasibility of an online hypnotic intervention for women with persistent pelvic pain. The secondary aim was to explore the effect of the hypnosis intervention on anxiety, depression, pain severity, coping, pain catastrophizing, and pain disability in comparison to a no-intervention control. Twenty women with persistent pelvic pain completed assessment questionnaires and were recruited from a variety of social media sites related to persistent pelvic pain and randomized to either control or hypnotic intervention groups. The intervention group completed a 7-week online hypnotic intervention. Results found a 30% dropout rate and modest compliance (90%-40%) with practice of audio recordings. Comments from the 7 participants who completed the hypnosis intervention indicated it was acceptable. Significant reductions in screening measures of anxiety and depression were found; however, there were no significant effects shown for pain severity, avoidant coping, pain catastrophizing, or pain disability. The intervention is potentially feasible, but further refinement and optimization is needed to increase retention, compliance, and potential effects.

The longitudinal association of symptom-related and psychological factors with health-related quality of life in patients with chronic pelvic pain syndrome

OBJECTIVE

To analyze the course of symptom-related measures, psychological variables and health-related quality of life (HRQoL) over a 12-month period, and to longitudinally examine symptom-related and psychological factors as predictors for HRQoL in male and female patients with chronic pelvic pain syndrome (CPPS).

METHODS

Data from 125 patients aged 19-83 years at baseline attending an interdisciplinary outpatient clinic for CPPS were analyzed. Participants completed a self-administered questionnaire on subjective health issues, and a postal follow-up survey was conducted 12 months later. We assessed physical and mental HRQoL, CPPS symptom severity, pain intensity, severity of somatic, depressive and anxiety symptoms, pain catastrophizing, and data on treatments during the follow-up period. Data were analyzed using multilevel linear modelling.

RESULTS

CPPS symptom severity, pain intensity, and pain catastrophizing significantly decreased over time. HRQoL and levels of somatic symptoms, depressive symptoms and anxiety remained stable. Lower baseline levels of somatic symptoms were associated with an increase in physical HRQoL, and lower baseline levels of depressive symptoms, anxiety and pain catastrophizing were associated with an increase in mental HRQoL after 12 months. Treatment utilization was neither related to decrease in CPPS symptom severity, pain intensity and pain catastrophizing, nor to HRQoL after 12 months.

CONCLUSIONS

Our data suggest that CPPS is related to persistently diminished HRQoL. Somatic symptoms and psychological factors are important determinants of HRQoL and potential therapeutic targets. To evaluate the efficacy and impact of treatment on CPPS-related outcomes, future large-scaled studies should systematically assess detailed data about therapies patients receive in routine care.

Symptomatology and Serum Nuclear Magnetic Resonance Metabolomics; Do They Predict Endometriosis in Fertile Women Undergoing Laparoscopic Sterilisation? A Prospective Cross-sectional Study

Endometriosis is a common, chronic inflammatory condition, thought to have a higher incidence in symptomatic women, yet, commonly associated symptoms do not always correlate with the presence or severity of disease and diagnosis requires surgery. We prospectively collected data and assessed symptomology and NMR spectroscopy-based metabolomics of 102 women undergoing laparoscopic sterilisation at a tertiary referral centre in a cross-sectional study. Twelve women were incidentally diagnosed with endometriosis (11.7%). According to the pre-operative questionnaire, presence and absence of many symptoms usually attributed to endometriosis were declared at similar frequencies in women with or without endometriosis. Women with endometriosis reported apparently more persistent heavy periods (50% vs 18.9%), prolonged periods (25% versus 7.8%) and problems conceiving (27.3% versus 9%) than those without endometriosis. NMR could not discern any distinguishable differences in the serum metabolome between those with and without endometriosis. Our paper highlights the complex symptomology experienced by women, regardless of a surgical diagnosis of endometriosis. Previous literature and the current study failed to identify clear, distinguishable symptoms or biomarkers pertinent to surgically confirmed endometriosis in the general population. Therefore, development of effective, non-invasive tests for identifying this heterogenous benign condition, endometriosis, is likely to be challenging.

Treatment use and satisfaction in Australian women with endometriosis: A mixed-methods study

AIMS

This study aimed to document the frequency of conventional and complementary treatments used by Australian women with endometriosis and the perceived efficacy of these treatments; and to qualitatively explore women's treatment satisfaction.

METHODS

Using a mixed-methods design, 532 women with self-reported endometriosis were recruited from the community.

METHOD

Participants were asked about their medication, complementary and self-care treatment use, as well as perceived efficacy on a 0 (not effective) - 10 (extremely effective) numeric rating scale (NRS), and open-ended qualitative survey items about treatment satisfaction.

RESULTS

97% of women used medication for pain relief (mean perceived efficacy = 5.05) and 89% used complementary/ self-care strategies (mean perceived efficacy = 3.70), with medication rated as significantly more effective (p <.001). Content analysis of the qualitative data identified that 36% of women were dissatisfied with treatment, 34% were somewhat satisfied, and 24% were satisfied. We identified qualitative themes relating to: 1) Barriers to treatment, which included lack of access, stigma, and disappointment with medical professionals who were perceived as uncaring, unhelpful and in some cases, psychologically damaging; 2) The need for holistic, interdisciplinary care; and 3) Patient knowledge, advocacy and resilience in endometriosis management.

CONCLUSIONS

Our findings reveal important limitations in the current Australian healthcare model, including the need for patient-centred interdisciplinary care that treats the biopsychosocial needs of people with endometriosis; and widespread pain education, spanning medical training to community awareness.

The innervation of the bladder, the pelvic floor, and emotion: A review

The innervation of the pelvic region is complex and includes extensive neurologic pathways. The higher centres' organisation determining the pelvic floor and organs' function remains a challenge understanding the physiological and pain mechanisms. Psychological and emotional factors have a profound influence on the pelvic floor and organ dysfunction such as LUTS. LUTS are associated with stress, depression, and anxiety. Neuroception is a subconscious neuronal system for detecting threats and safety and might explain the permanent disturbance of higher brain centres maintaining functional urological and gastrointestinal disorders and sphincter dysfunction.

Pain catastrophizing is associated with pain thresholds for heat, cold and pressure in women with chronic pelvic pain

Background and aims Psychological traits such as pain catastrophizing may play a role in the development of chronic pelvic pain (CPP). Pain catastrophizing is the tendency to amplify negative cognitive and emotional pain processes. The Pain Catastrophizing Scale (PCS) assesses elements of pain catastrophizing divided into three subgroups of factors (rumination, helplessness and magnification). Previous studies have shown associations between CPP and increased pain sensitivity, widespread generalized hyperalgesia, and decreased pain thresholds, but the relation between pain catastrophizing and specific pain thresholds has not yet been widely examined in this patient group. The aims of this study were (a) to determine if catastrophizing is increased in women with CPP compared with pain-free women, (b) to assess the importance of pain catastrophizing, psychological distress variables, and subjective pain sensitivity for pain thresholds of heat, cold and pressure in these two groups, and (c) to determine whether psychological variables or pain thresholds best contribute to the differentiation between CPP and controls. Methods Thirty-seven women with chronic pelvic pain who underwent diagnostic laparoscopy on the suspicion of endometriosis participated along with 55 healthy and pain-free controls. All underwent quantitative sensory testing on six locations on the body to determine heat (HPT), cold (CPT) and pressure (PPT) pain thresholds. The PCS, the Pain Sensitivity Questionnaire (PSQ), the Hospital Anxiety Depression Scale, (HADS) demographics and clinical data were collected prospectively. Principal component analysis and orthogonal partial least square regressions were used to assess the associations between PCS scores and pain thresholds. Results The women with CPP scored significantly higher on PCS than the healthy controls. PCS-helplessness, PCS-rumination and HADS-depression were significantly associated with pain thresholds for the whole group. In the CPP group, PCS-rumination, body mass index and PSQ were significant regressors for HPT and CPT. The PCS and the HADS subscales were strongly intercorrelated in women with CPP and were stronger regressors of group membership than the three pain thresholds. In the group of healthy control women, no relationships were found to be significant. The psychological variables were somewhat stronger significant regressors than pain thresholds (also significant) for group membership. Conclusions Women with CPP have significantly higher pain catastrophizing scores than women without CPP. The pain catastrophizing rumination factor is significantly associated with pain thresholds of heat and cold in CPP women. PCS and HADS are strongly intercorrelated and PSQ correlates positively with these variables. It seems that the psychological variables are important for group differentiation. Implications The results clearly indicate the need for a multimodal assessment (bio-psycho-social) of CPP patients including psychological symptoms such as catastrophizing, anxiety and depression. The registration of semi-objective pain thresholds captures both specific pain sensitivity information (mechanical pressure, cold or heat) and the degree of wide spread pain hypersensitivity. There is a need for future larger studies investigating whether certain profiles in the clinical presentations (including pain thresholds and psychological variables) are associated with outcomes after different types of interventions.

Application of Bioinformatics Methods to Identify Key Genes and Functions in Chronic Pelvic Pain

Neuropathologic pain (NPP) occurs in most patients with chronic pelvic pain (CPP), and the unique physiological characteristics of visceral sensory neurons make the current analgesic effect of CPP patients not optimistic. Therefore, this study explored the possible biological characteristics of key genes in CPP through the bioinformatics method. CPP-related dataset GSE131619 was downloaded from Gene Expression Omnibus to investigate the differentially expressed genes (DEGs) between lumbar dorsal root ganglia (DRG) and sacral DRG, and the functional enrichment analysis was performed. A protein-protein interaction (PPI) network was constructed to search subnet modules of specific biological processes, and then, the genes in the subnet were enriched by single gene set analysis. A CPP mouse model was established, and the expression of key genes were identified by qPCR. The results showed that 127 upregulated DEGs and 103 downregulated DEGs are identified. Functional enrichment analysis showed that most of the genes involved in signal transduction were involved in the pathway of receptor interaction. A subnet module related to neural signal regulation was identified in PPI, including CHRNB4, CHRNA3, and CHRNB2. All three genes were associated with neurological or inflammatory activity and are downregulated in the sacral spinal cord of CPP mice. This study provided three key candidate genes for CPP: CHRNB4, CHRNA3, and CHRNB2, which may be involved in the occurrence and development of CPP, and provided a powerful molecular target for the clinical diagnosis and treatment of CPP.

Psychological Interventions for Women with Persistent Pelvic Pain: A Survey of Mental Health Clinicians

Objective

To establish which psychological therapies mental health professionals use with reference to the treatment of women with persistent pelvic pain conditions. This research investigates overall therapies and specific techniques that clinicians believe are the most effective with this patient group, and the challenges mental health clinicians face in administering interventions. The study aims to suggest improvements to clinical practice and establish directions for targeted future research.

Design

Cross-sectional survey design.

Methods

An online survey was developed to ask mental health clinicians questions regarding the therapies and techniques they use with women experiencing persistent pelvic pain, their perspective on their practice in this area. The survey was advertised on relevant social media and professional websites. Survey results were tabled, and chi-square statistical analyses were undertaken to examine differences in therapy use according to country and profession.

Results

Mental health clinicians predominantly utilized cognitive behavioral therapy, acceptance and commitment therapy and associated techniques for women with persistent pelvic pain conditions. The results of the chi-square analyses showed that psychologists were more likely to use cognitive behavioral therapy or acceptance and commitment therapy, than counsellors who preferred counselling interventions. Chi-square analyses showed that Australian clinicians used acceptance and commitment therapy with a higher frequency than mental health clinicians in other countries. Clinicians provided multiple insights into their experiences working with women affected by persistent pelvic pain and their opinions as to valuable future research directions.

Conclusion

Cognitive behavioral therapy, acceptance and commitment therapy, and mindfulness therapies were most commonly used by mental health clinicians working with women with persistent pelvic pain conditions, despite severely limited evidence for the use of these psychological interventions in this client group.

Pain and functionality improved when underlying neuromuscular dysfunction addressed in chronic pelvic pain patients

AIM

Examine the effects of treating underlying neuromuscular dysfunction in chronic pelvic pain (CPP) patients.

METHODS

A retrospective longitudinal study of 200 female and male patients with CPP was performed upon an Institutional Review Board (IRB) approval (IRB# 17-0761). The outpatient protocol consisted of ultrasound-guided trigger point injections to the pelvic floor musculature with peripheral nerve blocks once a week for 6 weeks in an outpatient setting. Pelvic pain and functionality were measured before and after treatment using the Visual Analogue Scale and the Functional Pelvic Pain Scale. Functionality categories assessed were intercourse, bladder, bowel, working, walking, running, lifting, and sleeping.

RESULTS

Pretreatment, mean VAS score was 6.44 (standard deviation [SD] = 2.50; p < 0.05, 95% confidence interval [CI] = 6.09-6.79). Posttreatment mean VAS score was 4.25 (SD = 2.63; p < 0.05, 95% CI = 3.88-4.61). The mean FPPS score before treatment was 10.77 (SD = 6.39; p < 0.05, 95% CI = 9.88-11.65). Posttreatment mean FPPS score was 7.42 (SD = 5.87; p < 0.05, 95% CI = 6.61-8.23). Analysis of subcategories within FPPS indicated statistically significant improvement in the categories of intercourse, working, and sleeping.

CONCLUSION

Findings show the treatment was efficient at decreasing pain in CPP patients. Results show promise for improving overall pelvic functionality, particularly within the categories of intercourse, sleeping, and working.

A systematic review and meta-analysis of the Endometriosis and Mental-Health Sequelae; The ELEMI Project

Background:

It is important to evaluate sequalae for complex chronic health conditions such as endometriosis and mental health disorders. Endometriosis impacts 1 in 10 women. Mental health outcomes can be a primary determinant in many physical health conditions although this is an area not well researched particularly in women’s health. This has been problematic for endometriosis patients in particular, who report mental health issues as well as other key comorbidities such as chronic pelvic pain and infertility. This could be partly due to the complexities associated with comprehensively exploring overlaps between physical and mental health disorders in the presence of multiple comorbidities and their potential mechanistic relationship.

Methods:

In this evidence synthesis, a systematic methodology and mixed-methods approaches were used to synthesize both qualitative and quantitative data to examine the prevalence of the overlapping sequalae between endometriosis and psychiatric symptoms and disorders. As part of this, an evidence synthesis protocol was developed which included a systematic review protocol that was published on PROSPERO (CRD42020181495). The aim was to identify and evaluate mental health reported outcomes and prevalence of symptoms and psychiatric disorders associated with endometriosis.

Findings:

A total of 34 papers were included in the systematic review and 15 were included in the meta-analysis. Anxiety and depression symptoms were the most commonly reported mental health outcomes while a pooled analysis also revealed high prevalence of chronic pelvic pain and dyspareunia.

Interpretation:

It is evident that small-scale cross-sectional studies have been conducted in a variety of settings to determine mental health outcomes among endometriosis patients. Further research is required to comprehensively evaluate the mental health sequalae with endometriosis.

Depression Partially Mediates the Association of Adverse Childhood Experiences with Pain Intensity in Patients with Chronic Pelvic Pain Syndrome: Results from a Cross-Sectional Patient Survey

OBJECTIVE

Adverse childhood experiences (ACEs), such as emotional and physical maltreatment, are linked to chronic pelvic pain syndrome (CPPS) in adults. Psychological factors are important in understanding CPPS. We aimed to determine the nature and frequency of ACEs in male and female patients with CPPS and to investigate whether somatic symptoms and psychological comorbidities mediate the relationship of ACE severity with pain intensity.

DESIGN

Cross-sectional study.

SETTING

Interdisciplinary outpatient clinic for CPPS in Hamburg, Germany.

SUBJECTS

Individuals with CPPS (n = 234) who were 18 to 84 years of age.

METHODS

Using a self-administered questionnaire, we assessed the history of ACEs (ACE Scale), pain intensity (McGill Pain Questionnaire), somatic symptoms (Patient Health Questionnaire-15]), depression (Patient Health Questionnaire-9), and anxiety (Generalized Anxiety Disorder Scale). Parallel mediation analysis was conducted to examine whether the association of ACE severity with pain intensity is mediated by somatic symptoms, depression, and anxiety.

RESULTS

Emotional abuse and neglect were reported more than twice as often as physical abuse and neglect (37.2% vs 17.1%). Depression partially mediated the association of ACE severity with pain intensity in the whole study population. In sex-stratified analyses, different patterns of associations were observed, but somatic symptoms predicted pain intensity in both sexes.

CONCLUSIONS

Emotional maltreatment was highly prevalent, supporting an increased consideration of psychological factors in CPPS and indicating the need to screen for ACEs in patients with CPPS. Findings further suggest that depression and somatic symptoms may be important targets for therapeutic interventions in patients with CPPS who have a history of childhood adversity.

Efficacy of capacitive resistive monopolar radiofrequency in the physiotherapeutic treatment of chronic pelvic pain syndrome: study protocol for a randomized controlled trial

BACKGROUND

Chronic pelvic pain syndrome (CPPS) is a multifactorial disorder that affects 5.7% to 26.6% of women and 2.2% to 9.7% of men, characterized by hypersensitivity of the central and peripheral nervous system affecting bladder and genital function. People with CPPS have much higher rates of psychological disorders (anxiety, depression, and catastrophizing) that increase the severity of chronic pain and worsen quality of life. Myofascial therapy, manual therapy, and treatment of trigger points are proven therapeutic options for this syndrome. This study aims to evaluate the efficacy of capacitive resistive monopolar radiofrequency (CRMRF) at 448 kHz as an adjunct treatment to other physiotherapeutic techniques for reducing pain and improving the quality of life of patients with CPPS.

METHODS

This triple-blind (1:1) randomized controlled trial will include 80 women and men with CPPS. Participants will be randomized into a CRMRF activated group or a CRMRF deactivated group and receive physiotherapeutic techniques and pain education. The groups will undergo treatment for 10 consecutive weeks. At the beginning of the trial there will be an evaluation of pain intensity (using VAS), quality of life (using the SF-12), kinesiophobia (using the TSK-11), and catastrophism (using the PCS), as well as at the sixth and tenth sessions.

DISCUSSION

The results of this study will show that CRMRF benefits the treatment of patients with CPPS, together with physiotherapeutic techniques and pain education. These results could offer an alternative conservative treatment option for these patients.

Chronic Pelvic Pain Educational Experience Among Minimally Invasive Gynecologic Surgery Fellows and Recent Graduates: A Needs Assessment

STUDY OBJECTIVE

Learning to evaluate and treat chronic pelvic pain (CPP) is an established curriculum objective within the Fellowship in Minimally Invasive Gynecologic Surgery (FMIGS). Our aim was to investigate current educational experiences related to the evaluation and management of CPP and the impacts of those experiences on FMIGS fellows and recent fellowship graduates, including satisfaction, confidence in management, and clinical interest in CPP.

DESIGN

The AAGL-Elevating Gynecologic Surgery Special Interest Group for pelvic pain developed a 33-item survey tool to investigate the following topics: (1) current educational experiences with the assessment and management of patients with CPP, (2) satisfaction with fellowship training in CPP, (3) perceived preparedness to treat patients with CPP, (4) plans to incorporate management of CPP into clinical practice, and (5) perceived desires to expand CPP exposure. Composite scores were created to examine experiences related to diseases associated with CPP and pharmaceutical and procedural treatment options.

SETTING

Electronic survey.

PATIENTS

Not applicable.

INTERVENTIONS

The survey was distributed via AAGL email lists and offered on FMIGS social media sites from August 2017 to November 2017 to all active FMIGS fellows and individuals who graduated the fellowship during the preceding 5 years.

MEASUREMENTS AND MAIN RESULTS

Fifty-three of 82 (65%) current FMIGS fellows and 104 of 169 (62%) recent fellowship graduates completed the survey. Only 66% of current fellows endorsed working with a fellowship faculty member whose clinical work focused on CPP. Most current fellows reported having a "good amount" of experience or "extensive" experience with superficial endometriosis (39/53, 74%) and deeply infiltrative endometriosis (34/53, 64%), whereas the majority reported having "no" or "little" experience with frequently comorbid conditions like irritable bowel syndrome (68%), pelvic floor tension myalgia (55%), and interstitial cystitis/painful bladder syndrome (51%). For both current fellows and recent graduates, increased CPP Disease Experience composite scores were associated with satisfaction with CPP training (current fellows odds ratio [OR] 1.9, p =.002; recent graduates OR 1.5, p < .001), perceived preparedness to treat patients with CPP (current fellows OR 2.0, p = .0021; recent graduates OR 1.5, p <.001), and the desire to incorporate the treatment of CPP into future clinical practice (current fellows OR 1.8, p = .0099; recent graduates OR 1.3, p = .0178). More than 80% (43/53) of current fellows indicated that they believed an expanded pelvic pain curriculum should be part of the FMIGS fellowship.

CONCLUSION

This needs assessment of FMIGS fellows and recent graduates suggests that there are gaps between FMIGS curriculum objectives and current educational experiences, and that fellows desire increased CPP exposure. Expansion and standardization of the CPP educational experience is needed and could lead to increased focus on this disease process among subspecialty benign gynecologic surgeons.

Depression, Anxiety, and Self-Directed Violence in Women With Endometriosis: A Retrospective Matched-Cohort Study

The purpose of this study was to compare the incidence of mental health outcomes in women in the United States with and without documented endometriosis. In a retrospective matched-cohort study using administrative health claims data from Optum's Clinformatics DataMart from May 1, 2000, through March 31, 2019, women aged 18-50 years with endometriosis (n = 72,677), identified by International Classification of Disease diagnosis codes (revisions 9 or 10), were matched 1:2 on age and calendar time to women without endometriosis (n = 147,251), with a median follow-up of 529 days (interquartile range, 195, 1,164). The rate per 1,000 person-years of anxiety, depression, and self-directed violence among women with endometriosis was 57.1, 47.7, and 0.9, respectively. Comparing women with endometriosis to those without, the adjusted hazard ratios and 95% confidence intervals were 1.38 (1.34, 1.42) for anxiety, 1.48 (1.44, 1.53) for depression, and 2.03 (1.60, 2.58) for self-directed violence. The association with depression was stronger among women younger than 35 years (P for heterogeneity < 0.01). Risk factors for incident depression, anxiety, and self-directed violence among women with endometriosis included endometriosis-related pain symptoms and prevalence of other chronic conditions associated with pain. The identification of risk factors for mental health conditions among women with endometriosis may improve patient-centered disease management.

Inflammatory Mediators and Pain in Endometriosis: A Systematic Review

BACKGROUND

pain is one of the main symptoms of endometriosis and it has a deleterious effect on a patients' personal and social life. To date, the clinical management of pain includes prolonged medication use and, in some cases, surgery, both of which are disruptive events for patients. Hence, there is an urgency for the development of a sufficient non-invasive medical treatment. Inflammation is one of the causative factors of pain in endometriosis. It is well established that inflammatory mediators promote angiogenesis and interact with the sensory neurons inducing the pain signal; the threshold of pain varies and it depends on the state and location of the disease. The inhibition of inflammatory mediators' synthesis might offer a novel and effective treatment of the pain that is caused by inflammation in endometriosis.

OBJECTIVES

patients with endometriosis experience chronic pelvic pain, which is moderate to severe in terms of intensity. The objective of this systematic review is to highlight the inflammatory mediators that contribute to the induction of pain in endometriosis and present their biological mechanism of action. In addition, the authors aim to identify new targets for the development of novel treatments for chronic pelvic pain in patients with endometriosis.

DATA SOURCES

three databases (PubMed, Scopus, and Europe PMC) were searched in order to retrieve articles with the keywords 'inflammation, pain, and endometriosis' between the review period of 1 January 2016 to 31 December 2020. This review has been registered with PROSPERO (registry number: CRD42020171018). Eligibility Criteria: only original articles that presented the regulation of inflammatory mediators and related biological molecules in endometriosis and their contribution in the stimulation of pain signal were included.

DATA EXTRACTION

two authors independently extracted data from articles, using predefined criteria.

RESULTS

the database search yielded 1871 articles, which were narrowed down to 56 relevant articles of interest according to the eligibility criteria.

CONCLUSIONS

inflammatory factors that promote angiogenesis and neuroangiogenesis are promising targets for the treatment of inflammatory pain in endometriosis. Specifically, CXC chemokine family, chemokine fractalkine, and PGE₂ have an active role in the induction of pain. Additionally, IL-1β appears to be the primary interleukin (IL), which stimulates the majority of the inflammatory factors that contribute to neuroangiogenesis along with IL-6. Finally, the role of Ninj1 and BDNF proteins needs further investigation.
