MEDLINE Abstracts: Vulvodynia

from Medscape Ob/Gyn & Women's Health
Posted 06/06/2003

Unexplained vulvar pain, sexual dysfunction, and psychological disability characterize vulvodynia, a syndrome that seems to be prevalent and underdiagnosed or misdiagnosed. Only since 1983 has vulvodynia been recognized as a diagnosis in the medical literature. We have had numerous requests from Medscape members to provide more information on this disorder. We invite you find out more about vulvodynia in this easy-to-navigate collection of recent MEDLINE abstracts compiled by the editors at Medscape.



 

Vulvodynia: The Challenge of "Unexplained" Genital Pain

Graziottin A, Castoldi E, Montorsi F, Salonia A, Maga T
J Sex Marital Ther. 2001;27:503-512

Vulvodynia is a clinical syndrome that may include unexplained vulvar pain, sexual dysfunction, and psychological disability. It is a multifactorial syndrome that should be diagnosed, if possible, with an intradisciplinary approach. This article discusses the diagnosis and treatment of vulvodynia, starting with a summary of the complex nervous system within the pelvis. Different clinical pictures and different subtypes of the syndrome have been described in order to identify the etiologic aspects that are essential for diagnosis and subsequent treatment. Clinical evaluation should stress attention to detailed "pain-mapping" and evaluation of past and present history. The gynecological examination should be an overall patient evaluation, incorporating global physical impression, change in posture due to pain and careful examination of the pelvic floor. Examination of the pelvic floor is frequently omitted. Leading to an incorrect diagnosis of psychogenic pain. Such a misdiagnosis can result in the dismissal of appropriate treatment. Proper evaluation requires a comprehensive, multidisciplinary approach that includes medical, rehabilitative, and psychological issues.

Vulvodynia: An introduction and Critical Review of a Chronic Pain Condition

Masheb RM, Nash JM, Brondolo E, Kerns RD
Pain.. 2000;86:3-10

Vulvodynia, or chronic vulvar discomfort, has become an increasingly recognized complaint in the medical literature. However, classification, assessment, and treatment for vulvodynia have not been universally established. There is a serious need for greater understanding of this disorder since evidence suggests, although not life-threatening, vulvodynia appears to have a significant impact on quality of life. This article reviews the medical and psychological literature on vulvodynia published since 1983, the first year vulvodynia was recognized as a diagnosis in the medical literature. The purpose of this article is to provide a review of the literature on diagnostic issues, treatment options, and psychosocial sequelae with the aim of highlighting areas in need of future research. Finally, suggestions are made for considering vulvodynia from a multidimensional, chronic pain perspective.

A Population-Based Assessment of Chronic Unexplained Vulvar Pain: Have We Underestimated the Prevalence of Vulvodynia?

Harlow BL, Stewart EG
J Am Med Womens Assoc.. 2003;58:82-88

Objectives: To estimate the prevalence of unexplained chronic vulvar pain (burning or sharp knifelike pain or pain on contact) in an ethnically diverse population-based sample of women.
Methods: We used town census directories to identify 4915 women age 18 to 64 from 5 ethnically diverse Boston communities and asked them to complete a self-administered questionnaire pertaining to current and past chronic lower genital tract discomfort (response rate 68%). We calculated the cumulative incidence and 95% confidence intervals by demographic and reproductive characteristics. Approximately 16% of respondents reported histories of chronic burning, knifelike pain, or pain on contact that lasted for at least 3 months or longer, and nearly 7% were experiencing the problem at the time of the survey. Chronic vulvar pain on contact decreased with increasing age, but the cumulative incidence of chronic burning and knifelike pain was similar across all ages. Contrary to earlier clinical assessments, white and African American women reported similar lifetime prevalences. However, Hispanic women were 80% more likely to experience chronic vulvar pain than were white and African American women. Women with histories of chronic vulvar pain were 7 to 8 times more likely to report difficulty and great pain with their first tampon use than were women without such histories. Nearly 40% of women chose not to seek treatment, and of those who did, 60% saw 3 or more doctors, many of whom could not provide a diagnosis.
Conclusion: Chronic unexplained vulvar pain is a highly prevalent disorder that is often misdiagnosed.

Characteristics of Women With Vulvar Pain Disorders: Responses to a Web-based Survey

Gordon AS, Panahian-Jand M, Mccomb F, Melegari C, Sharp S
J Sex Marital Ther.. 2003;29(Suppl 1):45-58

This article presents data contributed by 428 highly educated, internet-savvy women who frequented various vulvar pain discussion lists. The age range was in the reproductive years and older and over 90% were Caucasians. No country of origin was given. They had a number of distressing symptoms, including vulvar pain at rest and with contact, burning, itching, redness, and inflammation. Most felt that they had either vulvar vestibulitis, vulvodynia, or both, although they had other vulvar conditions as well. Many felt that yeast infections, stress, antibiotics, infections, and chemicals played a contributing role. There were a number of comorbidities, including irritable bowel syndrome, fibromyalgia, and interstitial cystitis. Sexual abuse was not a major issue. The vulvar pain destroyed or altered their sex lives, lowered their self-esteem, and affected their relationships. Often, they relied upon understanding partners, support groups, and hobbies but not the medical profession for comfort.

Characteristics and Initial Diagnoses in Women Presenting to a Referral Center for Vulvovaginal Disorders in 1996-2000

Hansen A, Carr K, Jensen JT
J Reprod Med.. 2002;47:854-860

Objective: To describe the demographics, presenting symptoms, physical examination and laboratory findings, and initial diagnoses in a cohort of women referred for evaluation of vulvovaginal problems. STUDY
Design: Descriptive review of medical records of new patients referred for evaluation of vulvar problems between January 1, 1996, and December 31, 1999. Electronic medical records and other documents were manually abstracted.
Results: Three hundred twenty-two women met the study criteria. The majority were Caucasian (93.8%) and married (63.9%). The mean age was 41 years, with a range of 13-88. The majority reported at least one vaginal delivery (72.9%) or cesarean section (10.6%). The most common symptoms were vulvar pain (86.3%), dyspareunia (70.8%), itching (36.0%) and skin changes (18.0%). Most patients received a diagnosis in more than one evaluation category. Prevalent diagnoses included Bartholin fossa pain (12.1%), vulvar vestibulitis (19.9%), restriction and fissuring of the posterior labial commissure (20.1%), dysesthetic vulvodynia (32.3%), pelvic floor dysfunction (39.8%) and dermatologic conditions (47.5%).
Conclusion: Women presenting for evaluation of vulvar disorders represent a heterogeneous population. Among women with vulvar pain, abnormalities of the skin and pelvic floor are common and should be ruled out prior to making a diagnosis of vulvar vestibulitis or dysesthetic vulvodynia.

Clinical Profile of Vulvodynia Patients. A Prospective Study of 300 Patients.

Sadownik LA
J Reprod Med.. 2000;45:679-684

Objective: To define the demographic and clinical characteristics of women presenting with vulvodynia. STUDY
Design: Vulvodynia patients seen by the author between September 1996 and June 1999 were included in the study. Patients completed a standardized questionnaire and were interviewed and clinically examined.
Results: Three hundred one patients completed the questionnaire. The average age was 38 years old, 72% reported postsecondary education, 54% were nulligravid, and 55% were married. Average duration of symptoms was 38 months. Patients reported dyspareunia (71%), vulvar burning (57%) and vulvar itching (46%). One-third reported problems with sexual response. The majority (64%) reported a "history" of yeast infections. Over 64% of the time all therapeutic interventions tried by patients made the vulvar symptoms no better or worse. Approximately 55% reported another chronic health condition. Positive physical findings were often limited to inflammation in the vestibule (25%) and pain on palpation of the posterior vestibule (69%). Patients reported that their vulvodynia limited their physical activities.
Conclusion: Physicians should approach management of vulvodynia using a chronic pain model that emphasizes multidisciplinary health care and "improvement" in health, rather than single interventions and cure of disease.

Vulvar Pain. Psychological Profiles and Treatment Responses

Schmidt S, Bauer A, Greif C, Merker A, Elsner P, Strauss B
J Reprod Med.. 2001;46:377-384

Objective: To compare the psychological and quality of life profiles of women with different subsets of vulvodynia and identify differential response patterns to a combined gynecologic-dermatologic treatment program. STUDY
Design: Fifty-three women with vulvar dermatoses, dysesthetic vulvodynia and vulvar vestibulitis were recruited from a combined dermatologic and gynecologic vulvar clinic and completed instruments related to quality of life (QoL) and psychologic symptomatology. A repeated measurement design was employed. However, only 33 women could be assessed at the second point of measurement.
Results: Women with different subsets of vulvodynia showed (1) distinct quality of life and psychological profiles, and (2) different response patterns to treatment. There were significant differences on most QoL scales, with patients with dysesthetic vulvodynia and with vulvar dermatoses showing greater impairment than patients with vestibulitis. However, patients with vestibulitis displayed a highly specific pattern of psychologic symptomatology. Patients with vulvar dermatoses had an improvement in problems related to intimacy than patients with vulvar pain syndromes.
Conclusion: Treatment intervention studies seem to be indispensable in order to gain a better understanding of the complex interplay between different subsets of vulvodynia and psychological symptoms concurrently with differential treatment reactions.

Psychosocial and Sexual Functioning in Women With Vulvodynia and Chronic Pelvic Pain. A Comparative Evaluation

Reed BD, Haefner HK, Punch MR, Roth RS, Gorenflo DW, Gillespie BW
J Reprod Med.. 2000;45:624-632

Objective: To determine whether women with vulvodynia differ from women with chronic pelvic pain and normal controls in their psychological functioning, somatic preoccupation, pain experience and sexual functioning. STUDY
Design: Cross-sectional, self-report study of women presenting to University of Michigan specialty and general clinics for the treatment of vulvodynia or chronic pelvic pain or seeking a routine gynecologic examination. All subjects completed questionnaires assessing demographic characteristics, pain, depressive symptoms, general affective state, marital adjustment, functional activity, somatic complaints, exposures, and medical and sexual history. Univariate analyses, chi 2 tests, analyses of variance and logistic regression were used to assess associations between these variables and the diagnostic category.
Results: Women with vulvodynia (n = 31) were similar to asymptomatic control women (n = 23) in demographic characteristics, sexual relationship variables, sexual behaviors, current and past depression, somatic sensitivity, and history of sexual or physical abuse. Women with chronic pelvic pain (n = 18) were younger and less educated than the other two groups and were more likely to have a history of physical and sexual abuse, to report recent depression and to screen positive for current depression, to have more work absences and to have more somatic complaints.
Conclusion: Women with vulvodynia are psychologically similar to control women but differ significantly from women with chronic pelvic pain. A primary psychological cause of vulvodynia is not supported.

Burning Mouth Syndrome and Vulvodynia Coexisting in the Same Patient: A Case Report

Gaitonde P, Rostron J, Longman L, Field EA
Dent Update.. 2002;29:75-76

The 'dynias' are a group of chronic focal pain syndromes with a predilection for the orocervical and urogenital regions. This is a case report of stomatodynia (burning mouth syndrome) and vulvodynia coexisting in a middle-aged woman. The dynias are an enigma in terms of aetiology, which is multifactorial, making clinical investigations difficult and often requiring liaison with other specialties.

Vulvodynia After CO2 Laser Treatment of the Female Genital Mucosa

Tschanz C, Salomon D, Skaria A, Masouye I, Vecchietti GL, Harms M
Dermatology.. 2001;202:371-372

We have observed 3 cases of vulvodynia after CO2 laser (pulse or scan) treatment of condylomata acuminata (n = 1) or bowenoid papulosis (n = 2) of the female genital mucosa. Laser treatment was associated with a considerable delay in healing (3-4 months) and chronic pain. The histology of the treated areas showed a scar tissue and severe mucosal atrophy. The occurrence of painful scars following CO2 laser treatment could be related to an inadequate laser technique considering the morphology of the vagina.

Vulvodynia: An Indicator or Even an Early Symptom of Vulvar Cancer

Fischer M, Marsch WC
Cutis.. 2001;67:235-238

Vulvodynia is a symptom of chronic, painful vulvar discomfort of multicausal origin. Vulvar cancer is an underestimated cause of vulvodynia. Even early stages of vulvar neoplasia can lead to aching lesions. Three cases of vulvar carcinoma eliciting persistent pain have been diagnosed within a 2-year period. In 2 of our case studies, women had antecedent periods of vulvar pruritus of long duration (5 and 20 years, respectively). We conclude that early histologic examination of all visible vulvar lesions is necessary to exclude the presence of malignant vulvar neoplasia.

Pain Measurement in Vulvodynia

Pukall CF, Payne KA, Binik YM, Khalife S
J Sex Marital Ther.. 2003;29(Suppl 1):111-120

Current approaches to the conceptualization of vulvodynia focus either on issues of sexuality or underlying pathophysiology but tend to neglect the central symptom of pain. An adequate understanding of this condition will not be achieved, however, without examining all three factors and how they interact. A multiaxial pain approach has provided data regarding the intensity, location, temporal pattern, underlying system, and sensory quality of vulvodynic pain. In addition, standardized vulvar pain measurement techniques, including a new device called a vulvalgesiometer, have been developed, making possible the collection of reliable pain ratings. To date, this approach has been promising for the differential diagnosis, classification, and understanding of vulvar pain conditions.

Developments in Vulvovaginal Care

Stewart EG
Curr Opin Obstet Gynecol.. 2002;14:483-488

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.

Vulvodynia -- New and More Effective Approaches to Therapy

Bates CM, Timmins DJ
Int J STD AIDS.. 2002;13:210-212

Two cases are described of treatment-resistant vulvodynia that responded well to gabapentin. Gabapentin, an anti-epileptic drug, has been used in the treatment of neuropathic pain such as diabetic neuropathy and post-herpetic neuralgia. However, there has been little experience of its use in the relief of symptoms in vulvodynia and we add our observations to the one report of its use in these circumstances that has been published so far.

Vulvodynia: A Dermatologist's Perspective With Emphasis on an Irritant Contact Dermatitis Component

O'Hare PM, Sherertz EF
J Womens Health Gend Based Med.. 2000;9:565-569

Vulvodynia (vulvar burning and itching) is a symptom complex with a number of potential triggering/exacerbating factors. We reviewed the management and outcomes of 60 patients seen in a referral dermatology clinic for vulvodynia. The composite patient profile is that of a 44-year-old white woman with a 2-year history of vulvar burning who has tried multiple topical therapies. Dermatological factors in these patients included candidiasis (37%), atopy (27%), dermatographism (27%), and irritant contact dermatitis (83%). Identification of these factors and directed management led to symptomatic improvement in 72% of patients within 4 months. No patients were treated with amitriptyline. A dermatological approach to discern the contributing factors for individual patients with vulvodynia can be helpful in directing therapeutic management.

Safety and Efficacy of Topical Nitroglycerin for Treatment of Vulvar Pain in Women With Vulvodynia: A Pilot Study

Walsh KE, Berman JR, Berman LA, Vierregger K
J Gend Specif Med.. 2002;5:21-27

Objective: To evaluate the safety and efficacy of topical nitroglycerin cream for the treatment of vulvar pain in women with vulvodynia.
Methods: A total of 34 women diagnosed with vulvodynia were included in this study. Patients were treated with 0.2% nitroglycerin cream in the clinic. The cream was applied directly to the skin at the genital/vulvar area where the pain was located. Patients who did not experience any adverse side effects were instructed to use the cream at home at least three times per week, 5-10 minutes prior to sexual relations. Patients completed a pretreatment pain scale at baseline and a posttreatment pain scale questionnaire 4-6 weeks later.
Results: Twenty-one patients completed both the pre- and posttreatment pain scale questionnaires, and 13 patients completed only the posttreatment pain questionnaire. Thirty-one patients (91.5%) stated that "overall" their pain had improved. Analysis of the pre- and posttreatment questionnaires revealed a significant decrease in pain intensity on a scale of 0 (no pain) to 5 (excruciating pain; 3.95-2.57; P < .000). There was also a significant decrease in the frequency of overall painful episodes on a scale of 0 (never) to 4 (always; 3.25-2.15, P < .006). All 21 patients reported "improvement" of pain during sexual activity (3.65-2.15; P < .005).
Conclusion: Topical nitro-glycerine is safe and effective in providing temporary relief of introital dyspareunia and vulvar pain in women with vulvodynia. Women who completed this study experienced significant improvement in their overall pain and pain with sexual activity after nitroglycerin use. A larger placebo-controlled study is necessary to establish the optimum dosage level and to minimize the side effects.

Dysesthetic Vulvodynia. Long-term Follow-up After Treatment With Surface Electromyography-assisted Pelvic Floor Muscle Rehabilitation

Glazer HI
J Reprod Med .. 2000;45:798-802

Objective: To determine the long-term follow-up status of dysesthetic vulvodynia patients who were asymptomatic at the termination of treatment using surface electromyography (sEMG)-assisted pelvic floor muscle rehabilitation.
Study Design: A chart review of the years 1994-1996 identified 62 patients with a diagnosis of dysesthetic vulvodynia on initial evaluation and who were asymptomatic at the termination of treatment. Forty-three of these patients responded to a survey requesting information on their pain, maintenance activities and treatments, daily functioning and sexual status since treatment termination.
Results: Thirty-eight of the 43 patients (88.4%) reported experiencing no vulvar pain since completion of treatment. Three patients reported a single episode of pain, and two patients reported two episodes each. All five of these patients reported the absence of any vulvar pain for a mean period of 19.8 months prior to completion of the survey. One hundred percent of the 43 dysesthetic vulvodynia patients studied reported being pain free a mean of 39.5 months after successful treatment termination. No vulvar pain-related treatments or significant restrictions on daily activities were reported. All patients reported sexual interest, pleasure and activity.
Conclusion: Surface electromyography-assisted pelvic floor muscle rehabilitation is an effective and long-term cure for dysesthetic vulvodynia.
