Self-Reported Neuropathic Pain Characteristics of Women With Provoked Vulvar Pain: A Preliminary Investigation

Does the addition of electrical stimulation or kinesiotherapy improve outcomes of amitriptyline treatment for women with vulvodynia? A randomized clinical trial

INTRODUCTION AND HYPOTHESIS

Women diagnosed with provoked vulvodynia frequently report a great deal of frustration in achieving symptomatic relief. Physical therapy and drug treatment are among the interventions most indicated by guidelines; however, whether those modalities are effective when combined remains unclear. The objective was to evaluate the effectiveness of adding a physical therapy modality compared with amitriptyline alone for the treatment of vulvodynia.

METHODS

Eighty-six women with vulvodynia were randomized to (G1) 25 mg amitriptyline, once a day (n=27), (G2) amitriptyline + electrical stimulation therapy (n=29) or (G3) amitriptyline + kinesiotherapy (n=30). All treatment modalities were administered for 8 weeks. The primary endpoint was the reduction in vestibular pain. Secondary measurements focused on sexual pain, frequency of vaginal intercourse, Friedrich score, and overall sexual function. Data were analyzed using intention-to-treat.

RESULTS

All treatment modalities resulted in a significant decrease in vestibular pain (p<0.001), sexual pain (p<0.05), Friedrich score (p<0.001), and an increase in the frequency of sexual intercourse (p<0.05). G3 was more effective than G1 at reducing sexual pain (G1: 5.3±3.3 vs G3: 3.2±2.7; p=0.01) and at improving sexual function (G1: 18.8±9.8 vs G3: 23.9±7.8; p=0.04).

CONCLUSION

Kinesiotherapy and electrotherapy additions to amitriptyline administration as well as amitriptyline alone, were effective at improving vestibular pain in women with vulvodynia. Women receiving physical therapy had the greatest improvement in sexual function and frequency of intercourse at post-treatment and follow-up.

Moderators of the Relationship Between Pain and Pain-Related Sexual Disability in Women with Provoked Vestibulodynia Symptoms

BACKGROUND

Previous studies have demonstrated the deleterious effects of pain anxiety (ie, the degree to which one fears pain), stress, and solicitous partner responses (ie, expressions of sympathy and attention to one's partner's pain) on pain and pain-related disability, but little is known about whether these variables moderate the robust pain-pain-related disability relationship in individuals with provoked vestibulodynia (PVD).

AIM

We investigated whether pain anxiety, stress, and solicitous partner responses moderated the relationship between penetrative pain and pain-related sexual disability in women with PVD symptoms.

METHODS

Participants with PVD symptoms (N = 65, age range = 18-73 years) completed an online survey assessing pain anxiety (Pain Anxiety Symptoms Scale-20), perceived stress (Perceived Stress Scale), solicitous partner responses (WHYMPI Solicitous Responses Scale), penetrative pain (Female Sexual Function Index), and pain-related sexual disability (Pain Disability Index). Moderated regression analyses were performed using pain anxiety, stress, and solicitous partner responses as moderators of the relationship between penetrative pain, and pain-related sexual disability.

OUTCOMES

Outcomes in the current study included the moderating effect of pain anxiety, perceived stress, and solicitous partner responses on the relationship between penetrative genital pain and pain-related disability in sexual behavior.

RESULTS

Higher genital pain from penetrative intercourse and higher pain anxiety significantly predicted higher pain-related sexual disability, but perceived stress was not significantly related to sexual disability. Solicitous partner responses were significantly positively correlated with pain-related sexual disability. None of the moderators significantly moderated the pain-pain-related sexual disability relationship.

CLINICAL IMPLICATIONS

For women with PVD, pain anxiety and solicitous partner responses to their pain may exacerbate their pain-related sexual disability, signifying that pain anxiety and solicitous partner responses represent important targets of therapeutic intervention for women with PVD.

STRENGTHS AND LIMITATIONS

The present study extended past research on the relationships between psychological and behavioral factors and pain in women with PVD symptoms by demonstrating the deleterious relationship between pain anxiety, solicitous responses, and pain-related sexual disability. However, the study was correlational in nature, which precludes conclusions about the effect of pain anxiety, and solicitous partner responses on pain-related sexual disability.

CONCLUSION

High pain anxiety and frequent solicitous partner responses to an individual's pain predicted higher pain-related sexual disability, suggesting that it may be possible to improve the quality of life of PVD sufferers through interventions that aim to decrease pain anxiety, and solicitous partner responses, in addition to interventions that aim to decrease pain per se.

Pain, Anxiety, Depression, and Quality of Life in Patients with Vulvodynia

BACKGROUND/AIMS

The term vulvodynia refers to vulvar pain of unknown origin lasting at least 3 months. Psychiatric comorbidities are a common feature and, along with pain, may severely affect patients' wellbeing. We aimed to determine the characteristics of pain in vulvodynia, to correlate characteristics with symptoms of anxiety and depression, and to analyse the impact of these factors on patients' quality of life.

METHODS

This cross-sectional observational study analysed pain, anxiety, and depression and the effects of these factors on quality of life. Pain, anxiety, and depression were assessed using validated tools in 110 women.

RESULTS

Statistical analyses found correlations between pain and anxiety and between anxiety and worsened quality of life. Patients often reported stinging, burning, pain, itching, and dyspareunia, pointing to the importance of temporal, localisation, punctate pressure, thermal, tactile sensitivity, and emotional tension characteristics. Most patients had severe pain related to psychiatric comorbidities and decreased quality of life.

CONCLUSION

Using descriptors of pain quality and assessing anxiety and depression might help to define subgroups of patients that may benefit from different therapeutic approaches and thus enable treatments to be tailored to individual patients.

[Method of determining disease severity in women with pelvic varicose veins]

BACKGROUND

Using assessment scales in clinical and research practice is one of fundamental reference methods of evaluation in human pathological states. Pelvic vein varicosity is an independent nosological entity within the framework of chronic vein diseases. Currently, the clinical methods of assessment in the aspect of a patient-oriented approach in this type of disease are largely understudied and still not duly defined.

AIM

The study was aimed at analyzing clinical outcomes of surgical treatment in the form of resection of the ovarian vein in female patients with pelvic varicose veins, based on the developed specialized scale of clinical assessment of disease severity.

PATIENTS AND METHODS

We carried out an open prospective study of efficacy of resection of the ovarian vein in 37 women with pelvic varicose veins. The main criterion for assessment was a clinical method of determining manifestations of the disease by means of the Pelvic Venous Clinical Severity Score.

RESULTS

According to the Pelvic Venous Clinical Severity Score, improvement of the condition was observed in 36 (97.3%) operated female patients and 1 (2.7%) woman turned out to have negative dynamics. The median of the composite score of the severity scale decreased form 11.78±5.06 points to 5.22±3.19 (p<0.05). The total positive gradient of the score amounted to 6.57±3 .65 points. A significant decrease in manifestations of severity was observed for 9 of the 10 clinical descriptors of the disease.

CONCLUSION

The use of the suggested scale in practical assessment of the results made it possible to prove high efficacy of resection of the ovarian vein in women with pelvic varicose veins in the form of decreased intensity of the disease's symptomatology. The VCSS is an easy-to-fill-in tool, taking up little time, ensuring no influence of the physician's personality on the answers, presenting quantitative expression of therapeutic results.

Sensory pain characteristics of vulvodynia and their association with nociceptive and neuropathic pain: an online survey pilot study

Supplemental Digital Content is Available in the Text.

Objectives:

To evaluate self-reported sensory pain scores of women with generalized vulvodynia (GV) and provoked vestibulodynia (PVD), characterize pain phenotypes, and assess feasibility of using the Internet for recruitment and data collection among women with vulvodynia.

Methods:

Descriptive online survey. Data collected using an online survey accessed via a link on the National Vulvodynia Association web site. Convenience sample, 60 women aged 18 to 45 years (mean = 32.7 ± 5.5); 50 white, 2 black/African American, 4 Hispanic/Latino, and 4 Native American/Alaskan Native, diagnosed with vulvodynia, not in menopause. Pain assessment and medication modules from PAINReportlt.

Results:

Women with GV (n = 35) compared to PVD (n = 25). Estimated mean pain sites (2.5 ± 1.4 vs 2.2 ± 1.0, P = 0.31), mean current pain (8.7 ± 1.4 vs 5.5 ± 4.0, P = 0.0008), worst pain (8.1 ± 1.8 vs 6.1 ± 3.6, P = 0.02), and least pain in the past 24 hours (4.4 ± 1.8 vs 2.0 ± 2.0, P < 0.0001). Average pain intensity (7.1 ± 1.2 vs 4.6 ± 2.9, P = 0.0003) on a scale of 0 to 10, mean number of neuropathic words (8.3 ± 3.6 vs 7.7 ± 5.0), and mean number of nociceptive words (6.9 ± 4 vs 7.5 ± 4.4). Nineteen (54%) women with GV compared to 9 (38%) with PVD were not satisfied with pain levels.

Conclusion:

Women with GV reported severe pain, whereas those with PVD reported moderate to severe pain. Pain quality descriptors may aid a clinician's decisions about whether to prescribe adjuvant drugs vs opioids to women with vulvodynia.

Chronic Pelvic Pain: Assessment, Evaluation, and Objectivation

Chronic Pelvic Pain (CPP) and Chronic Pelvic Pain Syndrome (CPPS) have a significant impact on men and women of reproductive and nonreproductive age, with a considerable burden on overall quality of life (QoL) and on psychological, functional, and behavioural status. Moreover, diagnostic and therapeutic difficulties are remarkable features in many patients. Therefore evaluation, assessment and objectivation tools are often necessary to properly address each patient and consequently his/her clinical needs. Here we review the different tools for pain assessment, evaluation, and objectivation; specific features regarding CPP/CPPS will be highlighted. Also, recent findings disclosed with neuroimaging investigations will be reviewed as they provide new insights into CPP/CPPS pathophysiology and may serve as a tool for CPP assessment and objectivation.
