Clinical course of chronic pelvic pain in women

Evaluation of goserelin effectiveness based on assessment of inflammatory cytokines and symptoms in uterine leiomyoma

Background Uterine leiomyoma is a benign tumour of the uterine smooth muscles associated with an elevated level of inflammatory cytokines. Goserelin, a synthetic gonadotropin-releasing hormone analogue, suppresses the production of sex hormones and release of inflammatory cytokines in uterine leiomyoma cells. Objective The primary objective of this study was to find out the effectiveness of subcutaneous goserelin therapy on lowering serum levels of inflammatory cytokines and improving uterine leiomyoma-related symptoms in female patients diagnosed with uterine leiomyoma. The secondary objective was to assess the tolerability to goserelin therapy used in the management of this tumour. Setting Outpatient gynaecological clinic of the medical consultation department of Baghdad Teaching Hospital, Baghdad province, Iraq. Methods A single centre, prospective, longitudinal, cohort study was carried out on female patients diagnosed with uterine leiomyoma. Goserelin 3.6 mg subcutaneous injection was given in a consecutive monthly dose for the total time duration of three months. Serum levels of inflammatory cytokines, tumour necrosis factor-α and monocyte chemotactic protein-1 were detected before and after goserelin therapy in a consecutive monthly assessment. The study also assessed the improvement in uterine leiomyoma-related symptoms, including pelvic pain alongside the incidence of goserelin-related side effects during therapy schedules. Main Outcome Measures Assessment of serum levels of tumour necrosis factor-α and monocyte chemotactic protein-1 alongside uterine leiomyoma-related symptoms, including pelvic pain and goserelin-related side effects. Results There was a significant decrease in serum levels of tumour necrosis factor-α and monocyte chemotactic protein-1 compared to the baseline level over the 3-month duration of goserelin therapy (0.11 ± 0.02 vs. 0.74 ± 0.19) pg/mL; (0.07 ± 0.00 vs. 0.44 ± 0.18) pg/mL respectively. Patients showed a clinical improvement regarding uterine leiomyoma-related symptoms following each of the consecutive monthly doses of goserelin therapy (n = 11, 55%, P < 0.0001; n = 15, 75%, P < 0.0001; n = 18, 90%, P < 0.0001) respectively. This also includes a significant decrease in the intensity of leiomyoma-related pelvic pain before and after goserelin therapy (7.2 ± 1.43 vs. 3.05 ± 1.14, P < 0.0001). The majority of patients reported vaginal dryness (60%) as the main goserelin-related side effect. Conclusion Goserelin therapy reduces serum levels of inflammatory cytokines, tumour necrosis factor- α and monocyte chemotactic protein-1, improving leiomyoma-related symptoms with good tolerability in patients with uterine leiomyoma.

Endometriosis and pain in the adolescent- striking early to limit suffering: A narrative review

Endometriosis, a condition in which uterine tissue grows outside the uterus, is a debilitating disease, affecting millions of women and costing the United States approximately $78 billion annually in pain- related disability. It is also the leading cause of chronic pelvic pain (CPP), which is often unresponsive to existing treatments. Adolescent women with the disease are at particular risk as there are often significant diagnostic delays, which in turn can exacerbate pain. Research and treatment guidelines for adolescents with endometriosis are largely based on studies for adult women due to the limited number of studies focusing on adolescents. The current paper critically reviews the literature as it pertains to endometriosis pathophysiology, mechanisms contributing to CPP, and treatment implications and recommendations with a focus on gaps related to adolescents.

Chronic pelvic pain in an interdisciplinary setting: 1-year prospective cohort

BACKGROUND

Chronic pelvic pain affects ∼15% of women, and presents a challenging problem for gynecologists due to its complex etiology involving multiple comorbidities. Thus, an interdisciplinary approach has been proposed for chronic pelvic pain, where these multifactorial comorbidities can be addressed by different interventions at a single integrated center. Moreover, while cross-sectional studies can provide some insight into the association between these comorbidities and chronic pelvic pain severity, prospective longitudinal cohorts can identify comorbidities associated with changes in chronic pelvic pain severity over time.

OBJECTIVE

We sought to describe trends and factors associated with chronic pelvic pain severity over a 1-year prospective cohort at an interdisciplinary center, with a focus on the role of comorbidities and controlling for baseline pain, demographic factors, and treatment effects.

STUDY DESIGN

This was a prospective 1-year cohort study at an interdisciplinary tertiary referral center for pelvic pain and endometriosis, which provides minimally invasive surgery, medical management, pain education, physiotherapy, and psychological therapies. Exclusion criteria included menopause or age >50 years. Sample size was 296 (57% response rate at 1 year; 296/525). Primary outcome was chronic pelvic pain severity at 1 year on an 11-point numeric rating scale (0-10), which was categorized for ordinal regression (none-mild 0-3, moderate 4-6, severe 7-10). Secondary outcomes included functional quality of life and health utilization. Baseline comorbidities were endometriosis, irritable bowel syndrome, painful bladder syndrome, abdominal wall pain, pelvic floor myalgia, and validated questionnaires for depression, anxiety, and catastrophizing. Multivariable ordinal regression was used to identify baseline comorbidities associated with the primary outcome at 1 year.

RESULTS

Chronic pelvic pain severity decreased by a median 2 points from baseline to 1 year (6/10-4/10, P < .001). There was also an improvement in functional quality of life (42-29% on the pain subscale of the Endometriosis Health Profile-30, P < .001), and a reduction in subjects requiring a physician visit (73-36%, P < .001) or emergency visit (24-11%, P < .001) in the last 3 months. On multivariable ordinal regression for the primary outcome, chronic pelvic pain severity at 1 year was independently associated with a higher score on the Pain Catastrophizing Scale at baseline (odds ratio, 1.10; 95% confidence interval, 1.00-1.21, P = .04), controlling for baseline pain, treatment effects (surgery), age, and referral status.

CONCLUSION

Improvements in chronic pelvic pain severity, quality of life, and health care utilization were observed in a 1-year cohort in an interdisciplinary setting. Higher pain catastrophizing at baseline was associated with greater chronic pelvic pain severity at 1 year. Consideration should be given to stratifying pelvic pain patients by catastrophizing level (rumination, magnification, helplessness) in research studies and in clinical practice.

Pudendal nerve and branch neuropathy: magnetic resonance neurography evaluation

Pudendal neuralgia is being increasingly recognized as a cause of chronic pelvic pain, which may be related to nerve injury or entrapment. Due to its complex anatomy and branching patterns, the pudendal nerve abnormalities are challenging to illustrate. High resolution 3 T magnetic resonance neurography is a promising technique for the evaluation of peripheral neuropathies. In this article, the authors discuss the normal pudendal nerve anatomy and its variations, technical considerations of pudendal nerve imaging, and highlight the normal and abnormal appearances of the pudendal nerve and its branches with illustrative case examples.

The psychological profile of women presenting to a multidisciplinary clinic for chronic pelvic pain: high levels of psychological dysfunction and implications for practice

Objective

Chronic pelvic pain (CPP) is widely acknowledged as a common problem with significant consequences for those diagnosed with this condition. There is a lack of studies with good sample size that provide a comprehensive psychological profile of women presenting to specialist chronic pain clinics. Therefore, the objective of this study was to describe the psychological profile of a representative sample of women presenting with CPP at a tertiary referral center.

Design

This was a cross-sectional study. Women were asked to complete a questionnaire assessing symptoms of anxiety and depression, pain severity and interference, pain self-efficacy and catastrophizing beliefs, and sexual functioning.

Methods

One-hundred and seventy-five women with CPP were recruited when they attended their initial assessment at a specialist CPP clinic of the Royal Women’s Hospital, a public hospital in Melbourne, Australia.

Results

Over 75% of the participants had experienced pain for longer than 2 years. Fifty-three percent of women experienced either moderate or severe anxiety, and 26.7% experienced moderate-to-severe depression. There were strong correlations between depressive symptoms and pain interference, pain catastrophizing and self-efficacy beliefs.

Conclusion

Our findings confirm previous evidence for high levels of psychological distress and functional impairment associated with this condition, and extend these findings by including measures that are highly relevant to treatment planning, such as thinking styles and pain self-efficacy. Therefore, treatment of this complex condition needs to be holistic, and a multidisciplinary approach is likely to be the best way to achieve this.

Low back pain prevalence in Brazil: a systematic review

The article describes the methodological quality of published studies on prevalence of low back pain in Brazil. Eighteen studies were considered eligible after searches in the following electronic databases: LILACS, PubMed, Embase, CINAHL, SPORTDiscus and SciELO. A high source of bias was observed in the criteria for external validity related to sampling, in addition to non-response bias. Considering the criteria for internal validity, the main sources of bias were the lack of an acceptable definition of low back pain and the use of instruments that lacked proven reliability and validity. No representative study was found that provides a generalizable prevalence of low back pain in Brazil. The published studies included in this review showed a high risk of bias that affects the prevalence data. Future studies with appropriate methodological design are necessary to verify the real impact of low back pain in Brazil and allow comparisons.

Qualitative research as the basis for a biopsychosocial approach to women with chronic pelvic pain

Chronic pelvic pain (CPP) is a highly prevalent clinical condition and is recognized as a public health problem. Although the number of qualitative studies related to the topic is increasing, it is essential that this knowledge be presented in a synthesized manner, grounded in the context of the care provided to patients with CPP, in order to increase the clinical and research applicability of the findings. Little attention is given to CPP in undergraduate courses and in meetings for the continuing education of health professionals, the approach to CPP typically being based on the biomedical model. We believe that qualitative research can provide insights into CPP and form the basis for a biopsychosocial approach to the condition, which can in turn lead to better results, including resolution of the pain and greater patient/health professional satisfaction. Therefore, we conducted a metasynthesis of seven qualitative studies of CPP, the principal themes of which were as follows: (a) coping with CPP versus secondary gain; (b) the great importance of determining the cause of the pain; (c) expectations regarding the doctor-patient relationship; and (d) gender issues. We hope that the present study can aid in restoring the humanistic aspects of CPP treatment.

High prevalence of chronic pelvic pain in women in Ribeirão Preto, Brazil and direct association with abdominal surgery

INTRODUCTION

Chronic pelvic pain is a disease that directly affects the social and professional lives of women.

OBJECTIVE

To estimate the prevalence of this clinical condition and to identify independent factors associated with it in women living in Ribeirão Preto, Brazil.

METHODS

A one-year cross-sectional study was conducted in a population sample of 1,278 women over the age of 1,278 women over the age of 14 years. The target population was predominantly composed of women who are treated by the public health system. The questionnaire was administered by interviewers who were not linked to the city health care programs. The prevalence of the morbidity was estimated. First, we identified the significant variables associated with pelvic pain (p<0.10) and then we attributed values of 0 or 1 to the absence or presence of these variables. Logistic regression analysis was used to identify and estimate the simultaneous impact of the independent variables. The results were expressed by odds ratio and their 95% confidence interval with p<0.05.

RESULTS

The disease was found in 11.5% (147/1,278) of the sample. The independent predictors were dyspareunia, previous abdominal surgery, depression, dysmenorrhea, anxiety, current sexual activity, low back pain, constipation, urinary symptoms, and low educational level.

CONCLUSION

The prevalence of chronic pelvic pain in Ribeirão Preto is high and is associated with conditions that can usually be prevented, controlled, or resolved by improvement of public health policies and public education.

A cognitive behavioural based assessment of women with chronic pelvic pain

From population-based surveys, chronic pelvic pain (CPP) in women is a common condition with a spectrum of associated disability and distress. Those seen by gynaecologists in a referral setting often have substantial impairment of function and mood disturbance. Because in most cases, the aetiology of CPP cannot be explained and the range of effective interventions remains limited, treatment of CPP might easily result in a sense of frustration not only for the patient but also for the gynaecologist. To avoid this situation in clinical practice, a structured assessment of women suffering from CPP using a cognitive behavioural model, is suggested. This type of assessment provides information about the impact of CPP on a particular patient's daily life. It also facilitates referral for pain management. Future studies are needed to show further evidence of benefit of this approach for women with CPP.

EAU guidelines on chronic pelvic pain

CONTEXT

These guidelines were prepared on behalf of the European Association of Urology (EAU) to help urologists assess the evidence-based management of chronic pelvic pain (CPP) and to incorporate the recommendations into their clinical practice.

OBJECTIVE

To revise guidelines for the diagnosis, therapy, and follow-up of CPP patients.

EVIDENCE ACQUISITION

Guidelines were compiled by a working group and based on a systematic review of current literature using the PubMed database, with important papers reviewed for the 2003 EAU guidelines as a background. A panel of experts weighted the references.

EVIDENCE SYNTHESIS

The full text of the guidelines is available through the EAU Central Office and the EAU Web site (www.uroweb.org). This article is a short version of the full guidelines text and summarises the main conclusions from the guidelines on the management of CPP.

CONCLUSIONS

A guidelines text is presented including chapters on chronic prostate pain and bladder pain syndromes, urethral pain, scrotal pain, pelvic pain in gynaecologic practice, neurogenic dysfunctions, the role of the pelvic floor and pudendal nerve, psychological factors, general treatment of CPP, nerve blocks, and neuromodulation. These guidelines have been drawn up to provide support in the management of the large and difficult group of patients suffering from CPP.

Chronic pelvic pain in women: still a challenge

Chronic pelvic pain (CPP), a common condition particularly in reproductive-aged women, causes disability and distress, and significantly compromises quality of life and affects healthcare costs. The pathogenesis of CPP is still poorly understood and consequently poorly managed. Furthermore, the lack of a consensus on the definition of CPP greatly hinders epidemiological studies. Patients present with various associated problems, including bladder or bowel dysfunction, gynaecological pathologies or sexual dysfunction, and other systemic or constitutional symptoms. Other conditions, e.g. depression, anxiety and drug addiction, can also coexist. Effective management presupposes an integrated knowledge of all pelvic organs and other systems, including musculoskeletal, neurological and psychiatric systems. The key to treating CPP is to treat it as the complex disease it is. Treatment options range from conservative medical therapy to surgical intervention, and are primarily directed towards symptom relief. Unsatisfactory results of treatment render this condition a frustrating problem for both patients and physicians.
