Vulvodynia: the challenge of "unexplained" genital pain

Psychosocial factors associated with pain and sexual function in women with Vulvodynia: A systematic review

Background and objective

Vulvodynia is a prevalent chronic vulval pain condition affecting 10%–28% of women, and significantly impacting their health and quality of life. It is currently poorly understood and biomedical treatments achieve only modest benefits for pain and sexual functioning. A wider psychosocial conceptualization of this condition may improve outcomes. There is currently no coherent understanding of how psychosocial factors may contribute to outcomes in Vulvodynia. The aim of this review is to identify and systematically review psychosocial factors associated with pain and sexual outcomes and to inform a psychosocial model of Vulvodynia.

Databases and data treatment

Observational/experimental studies reporting on the association between psychosocial factors and pain/sexual outcomes in adult women with Vulvodynia were eligible. Two reviewers independently conducted eligibility screening, data extraction and quality assessment. Twenty‐one studies were included, all focused on women with Provoked Vestibulodynia (PVD). Most of the studies were low‐to‐medium quality.

Results/Conclusion

A range of general/pain‐related distress and avoidance processes, and sex/intimacy avoidance or engagement processes were significantly associated with pain, sexual functioning or sexual distress and sexual satisfaction, supporting the role of a psychosocial approach to PVD. Depression, anxiety, catastrophizing, pain‐anxiety, pain acceptance, body‐exposure anxiety, attention to sexual cues, partner hostility and solicitousness, self‐efficacy and penetration cognitions are highlighted as potentially important treatment targets in PVD. Due to the limited data available, developing a psychosocial model was not possible. Directions for future research include examining the replicability and generalizability of the factors identified, exploring differences/similarities across Vulvodynia subsets and testing tailored theoretically based treatments.

Significance

The systematic review highlights the role of psychosocial factors associated with pain and sexual functioning in Vulvodynia. The review findings reveal that Vulvodynia presents both similar and unique cognitive, behavioural and interpersonal features compared to other chronic pain conditions. There may be important roles for negative sexual cues, body image–related factors during intercourse, partner factors, self‐efficacy beliefs and penetration cognitions, in relation to pain and sexual functioning.

Why do young women continue to have sexual intercourse despite pain?

PURPOSE

Many young women suffer from pain and discomfort during sexual intercourse, and an increasing number of them seek help for their problems. It seems that some young women continue to have sexual intercourse despite pain. However, their motives are unclear.

METHODS

A total of 16 women, aged 14 to 20 years, with variable degrees of coital pain were selected at a youth center in a city in southeastern Sweden, to explore why they continued to have sexual intercourse despite pain. The women participated in audiotaped qualitative individual interviews, which were analyzed using the constant comparative method from grounded theory.

RESULTS

During the analysis we identified the core category striving to be affirmed in their image of an ideal woman and the categories resignation, sacrifice, and feeling guilt. The perceived ideal women had several distinct characteristics, such as willingness to have sexual intercourse, being perceptive of their partner's sexual needs, and being able to satisfy their partners. Having sexual intercourse per se was considered to be an affirmation of being a normal woman, irrespective of pain or discomfort.

CONCLUSIONS

These young women's focus on a constructed ideal explains why they continue to have sexual intercourse despite pain. Greater awareness of these beliefs among gynecologists, sexologists, and other healthcare professionals involved in the management of young women with coital pain would be beneficial.

Vulvodynia: case report and review of literature

Vulvodynia is defined as chronic vulvar burning, stinging, rawness, soreness or pain in the absence of objective clinical or laboratory findings to explain these symptoms. Vulvodynia is a chronic pain syndrome affecting up to 18% of the female population and is generally regarded as an underdiagnosed difficult to treat gynecological disorder. An increasing number of patients present with symptoms of vulvar pain, soreness, burning or irritation, which becomes chronic. Vulvodynia is a term used to describe chronic burning and/or pain in the vulva without objective clinical or laboratory findings to explain these symptoms. We present a case of vulvodynia accompanying somatoform disorder and depression.

Efficacy of functional electrical stimulation-biofeedback with sexual cognitive-behavioral therapy as treatment of vaginismus

OBJECTIVES

To report 12 cases of vaginismus that were successfully treated with functional electrical stimulation (FES)-biofeedback with sexual cognitive-behavioral therapy (SCBT) to determine the efficacy of FES-biofeedback with SCBT as a standard therapy for vaginismus. Vaginismus is an involuntary spasm of the musculature of the outer third of the vagina that leads to impossible vaginal penetration, causing personal distress. Various therapeutic approaches, both physiologic and psychological, have been considered.

METHODS

Twelve women with vaginismus referred from a checkup outpatient clinic participated in this study. The patients enrolled in this study had vaginismus according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders. The patients were assessed before and after treatment with gynecologic examinations and structured interviews pertaining to sexual function and psychological adjustment. After the diagnosis of vaginismus, we conducted weekly pelvic floor muscle relaxation using FES-biofeedback. Once the patients became tolerable to vaginal manipulation, the eight-stage SCBT (eight-stage gradual desensitization described by Kaplan using vaginal self-dilation with fingers and vaginal probe insertion) was added for 8 weeks.

RESULTS

After 8 weeks of treatment, all 12 couples had completed the program, had become tolerable to vaginal insertion of larger size probes, and could achieve satisfactory vaginal intercourse.

CONCLUSIONS

FES-biofeedback with SCBT is an effective aid for patients with vaginismus to learn muscle control. Therefore, it may increase the success rate of treatment of vaginismus.

Botulinum Toxin for the Treatment of Genital Pain Syndromes

Our purpose was to test the effect of botulinum toxin injections on hypertonic pelvic floor muscles of patients suffering from genital pain syndromes. We report two cases of women complaining of a genital pain syndrome resistant to pharmacological therapies and rehabilitation exercises associated with a documented involuntary tonic contraction of the levator ani muscle as a defense reaction triggered by vulvar pain. We performed botulinum toxin injections into the levator ani with the intent to relieve pelvic muscular spasms. Within a few days after the injections both the patients reported a complete resolution of the painful symptomatology, lasting for several months. Our experience suggests that botulinum injections are indicated in patients with genital pain syndrome with documented pelvic muscle hyperactivity, whose symptoms arise not only from genital inflammation and lesions, but also, and sometimes chiefly, from levator ani myalgia.

New concepts in vulvodynia

Vulvodynia is chronic vulvar burning/pain without clear medical findings. The etiology of vulvodynia is unknown and health care professionals should thoroughly rule out specific, treatable causes or factors such as dermatoses or group B Streptococcus infections. Vulvodynia is divided into 2 classes: vulvar vestibulitis syndrome is vestibule-restricted burning/pain and is elicited by touch; dysesthetic vulvodynia is burning/pain not limited to the vestibule and may occur without touch/pressure. After diagnosis, critical factors in successful patient management include education and psychological support/counseling. Unfortunately, clinical trials on potential vulvodynia therapies have been few. Standard therapy includes treating neuropathic pain (eg, tricyclic medications, gabapentin) thought to play a role. Additional therapies may be considered: pelvic floor rehabilitation combined with surface electromyography, interferon alfa, estrogen creams, and surgery. Importantly, any therapy should be accompanied by patient education and psychological support. Because definitive data on effective therapies are lacking, further clinical investigations of treatment options are warranted.

Developments in vulvovaginal care

Clinical studies on the myriad benign diseases of the vulva and vagina have long been outnumbered by emphasis on other areas of obstetrics and gynecology. The complexity of vulvovaginal diseases emerges in the recent literature. As clinicians embrace available knowledge, women's health will improve. This review encompasses current developments in candida, bacterial vaginosis, lichen sclerosus and vulvodynia.
