Complex Female Pelvic Pain: A Case Series From a Multidisciplinary Clinic in Urogynecology and Physiatry

Pain in the enthesis of levator ani muscle: A novel source of chronic pelvic pain

BACKGROUND

Managing chronic pelvic pain (CPP) remains a challenge due to its diverse range of causes. A newly identified anatomical entity known as the enthesis of the levator ani muscle (LAM) and its associated disorders might play a role. This paper describes a novel insight into CPP's origin, aiming to improve accurate diagnosis and treatment.

METHODS

Data were collected from medical records (paper or electronic) retrospectively. The study included 112 patients meeting the criteria, divided into CPP and non-CPP groups. Clinical symptoms, including location of LAM enthesis, referred pain from pain in LAM enthesis, and related lower urinary tract symptoms (LUTSs) were discussed. To identify differences in symptoms between the groups, a Chi-squared test and descriptive analyses were conducted.

RESULTS

Bimanual examination revealed tender sites in the attachment of the LAM to the pubic bone. LAM enthesis pain presumably caused referred pain in at least 10 areas, primarily in the lower abdominal quadrate (40.2%-47.3%) followed by the inguinal area (8.9%-15.1%). Multiple LUTSs were observed, including urinary frequency (72.3%), urgency (42.9%), nocturia (53.6%), residual urine sensation (64.3%), urinary incontinence (30.3%), painful bladder (34.8%), and weak urine stream (47.9%). Patients in the CPP groups experienced significant residual urine sensation (53.6%) and bearing-down sensation (42%) compared to the non-CPP group.

CONCLUSION

Pain in LAM enthesis is a novel cause of pelvic pain and LUTSs that warrants attention for the evaluation and management of CPP.

Prevalence of Paget's disease of bone: review of consecutive abdominopelvic CT scans and literature

BACKGROUND

Previous studies suggest an overall decrease of Paget's disease of bone (PDB) prevalence. However, a large number of asymptomatic patients make previously reported prevalence likely underrepresented.

PURPOSE

To evaluate the prevalence of PDB in our patient population.

MATERIAL AND METHODS

We retrospectively identified 1295 (mean age = 59 years; age range = 18-98 years) consecutive abdominopelvic computed tomography (CT) scans over a 15-day period in 2014. Abdominopelvic CT images were reviewed to assess for the presence of PDB in the lower thoracic spine, lumbar spine, pelvis, or proximal femora. This prevalence was compared with prevalence reported in earlier literature using Fisher's exact test.

RESULTS

Of the included patients, 5/1295 (0.39%) patients had imaging findings of PDB on abdominopelvic CT. Those five patients were all aged ≥55 years and had pelvic bone involvement, with one patient having additional involvement of multiple lower thoracic vertebral bodies. In our studied cohort, 812/1295 (62.7%) patients were aged ≥55 years, which corresponds to a prevalence of 0.62% (5/812) of PDB in patients aged ≥55 years. When accounting for fact that bones of the pelvis are involved in 40%-91% of patients with PDB, the prevalence is estimated at 0.43%-0.98% in the total adult population and estimated at 0.68%-1.55% in older adults. The prevalence was greater than two studies before 1960, and less than some studies during 1960-2019.

CONCLUSION

We found that the prevalence of PDB on abdominopelvic CTs was 0.39% of all adult patients with an increase after the age of 55 years.

A systematic review of diagnostic tests to detect pelvic floor myofascial pain

INTRODUCTION AND HYPOTHESIS

Myofascial pain arising from pelvic floor muscles occurs in women with vaginismus, interstitial cystitis and endometriosis but is often overlooked. The aim is to examine alternative diagnostic tests to detect pelvic floor myofascial pain compared with standardized vaginal palpation of pelvic floor muscles as the reference test.

METHODS

A systematic review was prospectively conducted (PROSPERO-CRD42020183092) according to PRISMA guidelines. Databases searched included Ovid Medline 1946-, Embase 1957-, Scopus 1960-, Cochrane Combined, Clinical trials, Google Scholar (top 200 articles), Web of Science, TRIP, BIOSIS, DARE, CINHAL, EmCare, PEDro, ProQuest and EBSCOhost up to July 2020. Articles were independently screened by two authors and assessed for bias using QUASDAS-2 tool.

RESULTS

A total of 26,778 articles were screened and 177 were selected for full text review, of which 5 were selected for final analysis. Five studies included 9694 participants of which 1628 had pelvic floor myofascial pain. Only one study reported data to calculate sensitivities and specificities of the index test, which utilized a score of > 40 on the Central Sensitization Inventory to detect women with pelvic floor myofascial pain and revealed a sensitivity of 34.8% and a specificity of 84.9% compared to the reference test.

CONCLUSIONS

This systematic review did not reveal any diagnostic test superior to the pre-defined reference test. There is a lack of consensus on the definition of pelvic floor myofascial pain and a lack of a validated diagnostic criteria which must be addressed to progress with meaningful research in this field.

No Association Between Intrauterine Contraceptive Devices and Musculoskeletal Hip Joint Pain

Purpose

To investigate the association between intrauterine device (IUD) use and hip pain, orthopaedic visits for hip pain, and arthroscopic hip surgery.

Methods

This was a retrospective cohort study of patients aged 18-44 years old using either IUDs or subdermal implants for contraception in a large commercial claims database (MarketScan) from 2012 to 2015. All patients had at least 12 months of continuous enrollment both before and after contraceptive placement. Patients with a history of hip pain or surgery were excluded. The primary outcome was new hip pain. Secondary outcomes included visiting an orthopaedic or sports medicine provider for a hip complaint, intra-articular hip injection, and arthroscopic hip surgery. Outcomes were analyzed with Cox proportional-hazard models.

Results

We identified a total of 242,383 patients, including 216,541 (89.3%) with IUDs and 25,842 (10.7%) with subdermal contraceptive implants. In time-to-event analysis, IUDs (vs implants) were not associated with increased risk of new hip pain diagnoses (hazard ratio [HR] 0.95, 95% confidence interval [CI] 0.87-1.03, P = .21). In contrast, both age (P < .001) and region (P < .001) were associated with increased risk of new hip pain. Similar results were seen for the secondary outcomes, including risk of orthopaedic visits for hip complaints (HR 1.06, 95% CI 0.83-1.35, P = .63), intra-articular injections of the hip (HR 0.94, 95% CI 0.63-1.41, P = .77), and hip arthroscopy procedures (HR 1.13, 95% CI 0.53-2.40, P = .75).

Conclusions

In this study, we found no evidence that IUDs were associated with hip pain or surgery.

Level of Evidence

Level III, retrospective cohort.

The role of the multi-disciplinary team and multi-disciplinary therapeutic protocol in the management of the chronic pelvic pain: There is strenght in numbers!

INTRODUCTION

The aim of the study is to evaluate the effectiveness of a Multi-disciplinary team (MDT) and multi-disciplinary approach in the treatment of Chronic Pelvic Pain (CPP).

METHODS

The data of all consecutive patients referred for a CPP from 11/2016 to 2/2019 has been prospectively collected. The sample was divided in two groups: Group A, made by patients managed after the institution of our MDT, and Group B, made of patients managed before this date. The MDT is composed by three urogynecologists, a psychologist and a physiotherapist. All Group A patients underwent a weekly bladder instillation with dimethyl sulfoxide (DMSO), kinesiotherapy for trigger points and Percutaneous Tibial Nerve Stimulation for 10 consecutive weeks. Patients were asked to perform a self-treatment following the Stanford Protocol and to adhere to a specific diet. All Group B patients were managed only with DMSO instillations and a strict diet.

RESULTS

The Group A was made of 41 females and 6 males while the Group B was made of 38 females and 5 males. The Group A patients showed a statistically significant improvement in the Pelvic Pain Urgency Frequency, in the frequency times reported at the 6 months voiding diary, and a better Patient Global Impression of Improvement.

CONCLUSIONS

Our data support the efficacy of the MDT in the management of CPP. The multimodal approach might represent an effective and reproducible non-invasive option to manage successfully CPP.

Clinical Outcomes of a Multidisciplinary Female Chronic Pelvic Pain Program

OBJECTIVE

The aim of this study was to describe patient-reported longitudinal outcomes in a multidisciplinary female chronic pelvic pain (CPP) program.

METHODS

We conducted a retrospective cohort study for women cared for in a tertiary, multidisciplinary, female (CPP) program between 2012 and 2017. Patient demographics were collected from electronic medical records. Patients completed the numerical rating scale for pain, Pain Disability Index (PDI), and Patient Global Impression of Improvement scale at each visit. Mixed-effects models were used to assess change in patient responses over time.

RESULTS

Patients (N = 317) with a mean age of 44.3 years (SD, 14.6) and median duration of symptoms of 3 years (interquartile range, 1.0-7.0) were assessed in this analysis. The primary diagnosis was pelvic floor myofascial pain (67%). On multivariable analysis, numerical rating scale scores decreased by -0.11 point [95% confidence interval (CI), -0.20 to -0.01] every 3 months (P = 0.03). On multivariable analysis, total PDI score decreased by -0.88 point (95% CI, -1.43 to -0.33) (P = 0.003), and PDI sexual subscores decreased by -0.29 point (95% CI, -0.44 to -0.14) (P < 0.001) every 3 months. A higher (worse) Patient Global Impression of Improvement score was associated with a higher (worse) PDI score at follow-up (odds ratio, 1.04; 95% CI, 1.01-1.07; P = 0.01).

CONCLUSIONS

Patients in a multidisciplinary CPP program demonstrated improvement over time in pain disability that was associated with an overall global impression of improvement.

Interdisciplinary Teams in Endometriosis Care

Endometriosis-associated chronic pelvic pain can at times be a complex problem that is resistant to standard medical and surgical therapies. Multiple comorbidities and central sensitization may be at play and must be recognized with the help of a thorough history and physical examination. If a complex pain problem is identified, most endometriosis expert reviews and guidelines recommend multidisciplinary care. However, there are no specific recommendations about what should be the components of this approach and how that type of team care should be delivered. There is evidence showing the effectiveness of specific interventions such as pain education, physical therapy, psychological therapies, and pharmacotherapies for the treatment of chronic pain. Interdisciplinary team models have been well studied and validated in other chronic pain conditions such as low back pain. The published evidence in support of interdisciplinary teams for endometriosis-associated chronic pain is more limited but appears promising. Based on the available evidence, a model for an interdisciplinary team approach for endometriosis care is outlined.

Chronic Pelvic Pain: ACOG Practice Bulletin, Number 218

Chronic pelvic pain is a common, burdensome, and costly condition that disproportionately affects women. Diagnosis and initial management of chronic pelvic pain in women are within the scope of practice of specialists in obstetrics and gynecology. The challenging complexity of chronic pelvic pain care can be addressed by increased visit time using appropriate coding modifiers, as well as identification of multidisciplinary team members within the practice or by facilitated referral. This Practice Bulletin addresses the diagnosis and management of chronic pelvic pain that is not completely explained by identifiable pathology of the gynecologic, urologic, or gastrointestinal organ systems. When evidence on chronic pelvic pain treatment is limited, recommendations are extrapolated from treatment of other chronic pain conditions to help guide management. The evaluation and management of potential gynecologic etiologies of pelvic pain (ie, endometriosis, adenomyosis, leiomyomas, adnexal pathology, vulvar disorders) are discussed in other publications of the American College of Obstetricians and Gynecologists ().
