Exploring Localized Provoked Vulvodynia: Insights from Animal Model Research.

Provoked vulvodynia represents a challenging chronic pain condition, characterized by its multifactorial origins. The inherent complexities of human-based studies have necessitated the use of animal models to enrich our understanding of vulvodynia's pathophysiology. This review aims to provide an exhaustive examination of the various animal models employed in this research domain. A comprehensive search was conducted on PubMed, utilizing keywords such as "vulvodynia", "chronic vulvar pain", "vulvodynia induction", and "animal models of vulvodynia" to identify pertinent studies. The search yielded three primary animal models for vulvodynia: inflammation-induced, allergy-induced, and hormone-induced. Additionally, six agents capable of triggering the condition through diverse pathways were identified, including factors contributing to hyperinnervation, mast cell proliferation, involvement of other immune cells, inflammatory cytokines, and neurotransmitters. This review systematically outlines the various animal models developed to study the pathogenesis of provoked vulvodynia. Understanding these models is crucial for the exploration of preventative measures, the development of novel treatments, and the overall advancement of research within the field.

Innervation of the human vulvar vestibule: A comprehensive review.

Pain of the vulvar vestibule, including provoked vestibulodynia, is prevalent among women, yet challenging to treat due to its multifactorial etiology. Recent evidence indicates a neuroproliferative subtype in which hypersensitivity of the vulvar vestibule is due, in part, to hyperinnervation. Detailed knowledge regarding the innervation of the vulvar vestibule is crucial to understanding and treating pain conditions impacting this region. The purpose of this review is to consolidate the current evidence regarding the innervation of the human vulvar vestibule and discuss the implications of this innervation for pathological conditions affecting this tissue. A comprehensive review of the literature was conducted using keywords including vulvar vestibule, innervation, and vestibulodynia to identify articles concerning the innervation of the vulvar vestibule. Fifteen studies published between 1998 and 2017 were reviewed. Evidence from immunohistochemical investigations support that the vulvar vestibule has nociceptive, mechanosensory, sympathetic, and parasympathetic innervation. In pathological samples, hyperinnervation supports the neuroproliferative etiology of provoked vestibulodynia. Additionally, there is some evidence supporting the role of the pudendal nerve in vulvar vestibule innervation, although no cadaveric studies have been reported to date. Progress has been made in our understanding of the innervation of the vulvar vestibule, though further research into the origin of sensory and autonomic innervation of this region is needed. Advancing the knowledge of vulvar vestibule innervation is crucial towards improving our understanding of the function of this tissue, in addition to informing the etiology and management of pain syndromes impacting this region.

Surgical Treatments of Chronic Vulvar Pain After Female Genital Mutilation/Cutting.

BACKGROUND: Vulvar and in particular clitoral pain can affect women with Female Genital Mutilation/Cutting (FGM/C). To date, there is no comprehensive study on the different available treatments for vulvar pain after FGM/C. AIM: To study the outcome of surgical treatments of vulvar and/or clitoral pain among women living with FGM/C. METHODS: Retrospective review of the consecutive medical files of all 506 women who consulted at a specialized outpatient clinic for women with FGM/C between April 1, 2010 and December 31, 2017. OUTCOME: Subjective change in chronic vulvar pain after surgical treatment. RESULTS: In total, 36.1% of women (n = 183) experienced chronic pain, all types included, among which 2.8% (n = 14) experienced provoked or unprovoked chronic vulvar pain. Among the 14 women with provoked or unprovoked chronic vulvar pain, ten (71.4%) underwent surgical treatment: 7 underwent resection of vulvar scar complications (cysts, bridles, adhesions) with (n = 4) or without (n = 3) concomitant defibulation, 3 had clitoral reconstruction and one had labium reconstruction with removal of peri-clitoral adhesion. Nine out of ten (90%) experienced resolution of pain after surgery and the remaining woman (10%) was lost to follow-up. CLINICAL IMPLICATIONS: Safe and effective surgical treatments exist and patients with chronic vulvar pain post-FGM/C should be referred to specialists who would consider appropriate indications for surgery and support informed decision-making and treatment. STRENGTHS & LIMITATIONS: The strengths of this research are the big sample size of women from diverse cultural and religious backgrounds, as well as the availability of pre- and postsurgery iconographic material and histology. Limitations include a subjective reporting of pain without validated questionnaires. CONCLUSION: Effective surgical treatments for provoked or unprovoked chronic vulvar pain post-FGM/C are clitoral reconstruction, defibulation, cystectomy, and bridle removal. Surgical treatments should be combined with a culturally sensitive multidisciplinary care and follow-up. Bazzoun Y., Aerts L., Abdulcadir J.

Vulvodynia - an evolving disease.

Vulvodynia is a common vulval pain syndrome that occurs most commonly in reproductive women of all ages. It can, in some cases, present for the first time after menopause. Up to about 15% of adult women have had symptoms of vulvodynia, with 4-5% currently symptomatic. Since there are no specific tests for diagnosis, vulvodynia is a diagnosis of exclusion. The condition is commonly associated with other chronic pain disorders and can be exceedingly debilitating, resulting in sexual dysfunction, severe depression and/or anxiety. It can significantly impair quality of life. Goals for long-term team approach management should be discussed with the patient at the commencement of each intervention as effectiveness of therapy is not assured. Currently, there is no intervention that effects cure in all individuals and a combination of pharmacological therapy, psychotherapy and physiotherapy, reserving surgery as a last-line option, is the best option for treatment. There are no long-term data on how long women will have symptoms and, if resolved, what provokes symptoms again in the future, whilst correlation between the etiology of vulvodynia and efficacy of treatment is not known.

Vulvodynia: a neuroinflammatory pain syndrome originating in pelvic visceral nerve plexuses due to mechanical factors.

This short opinion aimed to present the evidence to support our hypothesis that vulvodynia is a neuroinflammatory pain syndrome originating in the pelvic visceral nerve plexuses caused by the failure of weakened uterosacral ligaments (USLs) to support the pelvic visceral nerve plexuses, i.e., T11-L2 sympathetic and S2-4 parasympathetic plexuses. These are supported by the USLs, 2 cm from their insertion to the cervix. They innervate the pelvic organs, glands, and muscles. If the USLs are weak or lax, gravitational force or even the muscles may distort and stimulate the unsupported plexuses. Inappropriate afferent signals could then be interpreted as originating from an end-organ site. Activation of sensory visceral nerves causes a neuro-inflammatory response in the affected tissues, leading to neuroproliferation of small peripheral sensory nerve fibers, which may cause hyperalgesia and allodynia in the territory of the damaged innervation. Repair of the primary abnormality of USL laxity, responsible for mechanical stimulation of the pelvic sensory plexus, may lead to resolution of the pain syndrome.

Changes in the Vaginal Microbiota of Women With Secondary Localized Provoked Vulvodynia.

OBJECTIVE: The etiology of localized provoked vulvodynia (LPV) remains unknown, but observations suggest the involvement of the vaginal microbiota. We examined the vaginal microbiota of women with LPV and healthy controls, upon after a low-oxalate diet (LOD). MATERIALS AND METHODS: A total of 9 women diagnosed with secondary LPV and 21 healthy controls were recruited from the Galilee Medical Center in Israel and subjected to prospective evaluations of their vaginal microbiota. Total DNA was extracted from vaginal discharge samples provided before and after following LOD for 3 weeks and was then subjected to 16S sequencing. Data obtained were then used to evaluate α and ß diversity, identify differentially abundant bacterial taxa in LPV, and determine their impact on the metabolism. RESULTS: These evaluations revealed decreased diversity in the vaginal microbiota of women with LPV and identified the Ochrobactrum genus and Pseudomonadaceae family as indicators for LPV. In addition, we identified 23 differentially expressed bacterial metabolic pathways between the LPV and control samples and revealed that LOD could induce changes in the ß diversity of LPV vaginal microbiomes, which was further supported by some degree of pain reduction in patients. CONCLUSIONS: Localized provoked vulvodynia and LOD were associated with shifts in the vaginal microbiota. However, the impact of these changes on the development of LPV requires additional studies with a larger cohort.

High rate of dyspareunia and probable vulvodynia in Ehlers-Danlos syndromes and hypermobility spectrum disorders: An online survey.

Vulvodynia is debilitating vulvar pain accompanied by dyspareunia (pain with sexual intercourse). Ehlers-Danlos syndromes (EDS) and hypermobility spectrum disorders (HSD) may represent a predisposing factor for vulvodynia given a high rate of dyspareunia in these conditions. We conducted an online survey of women with EDS or HSD to assess rates of dyspareunia and estimate rates of vulvodynia, report rates of comorbid conditions common to EDS or HSD and vulvodynia, and examine rates of conditions contributing to dyspareunia in women with EDS or HSD. Women with EDS or HSD (N = 1,146) recruited via social media were 38.2 ± 11.5 years old, primarily White (94.4%), and resided in the United States (78.5%). 63.7% of participants reported dyspareunia and 50% screened positive for vulvodynia. The rate of comorbid conditions common to EDS or HSD and vulvodynia were: irritable bowel syndrome, 6.5%; fibromyalgia, 40.0%; temporomandibular joint dysfunction, 56.4%; migraine, 6.7%; interstitial cystitis, 1.7%; and mast cell activation syndrome, 10.2%. Participants reporting dyspareunia also reported ovarian cysts, fibroids, or abdominal or pelvic scars, 47.5%; endometriosis, 26.5%; and genital lacerations, 19.3%. Women with EDS or HSD may have a higher rate of vulvodynia (50.0%) than women in the U.S. population at large (8%) and should be assessed for dyspareunia and vulvodynia.

Clinical outcomes and adherence to topical corticosteroid therapy in women with vulvar lichen sclerosus: A retrospective cohort study.

BACKGROUND: Vulvar lichen sclerosus is a progressive dermatitis with significant itching, pain, and sexual dysfunction. OBJECTIVE: To investigate topical steroid use and clinical improvement across multiple specialties. METHODS: Retrospective cohort study at dermatology, gynecology, and vulvovaginal specialty clinics from 2012 to 2017. Descriptive statistics and panel logistic regression were performed. RESULTS: A total of 333 women attended 1525 visits (median 6/patient; range, 1-24 visits). Patients used steroids exactly as prescribed at 66% of visits, less than prescribed at 26%, and not at all at 8%. Versus no use, exact use improved symptoms (odds ratio [OR], 4.6; 95% confidence interval [CI], 2.2-9.6) and physical examination findings (OR, 6.9; 95% CI, 2.7-17.6) more than infrequent steroid use (symptoms: OR, 2.5; 95% CI, 1.2-5.4; physical examination findings: OR, 4.2; 95% CI, 1.6-11.0). Sexual activity status was noted in 93% of vulvovaginal, 29% of gynecology, and 0% of dermatology visits. At intake, 42% of women were sexually inactive because of pain; of these, 37% became sexually active after steroid treatment. Steroid adherence was not associated with change in sexual activity. CONCLUSIONS: Women with vulvar lichen sclerosus improve more when topical steroids are used exactly as prescribed, although some improvement occurs with imperfect use. Sexual activity documentation is inconsistent, limiting quality of life follow-up.

Vulvodynia.

Vulvodynia is a heterogenous, chronic pain condition of unknown etiology that affects 7% to 15% of women. It affects sexual function and quality of life. Vulvodynia can be primary or secondary, localized or generalized, and spontaneous or provoked. Contributing factors for provoked vulvodynia might include vulvovaginal infections, low estrogen states, and underlying anxiety disorder. Generalized vulvodynia likely arises from underlying connective tissue or neurological dysfunction. Vulvodynia treatment must be individualized on the basis of the patient's presentation and physical examination findings. Surgical excision of the vulvar vestibule has high success rates but other modalities showing success include pelvic floor physical therapy and cognitive-behavioral therapy.

Interpersonal trauma and aging-related genitourinary dysfunction in a national sample of older women.

BACKGROUND: Among reproductive-aged women, exposure to interpersonal trauma is associated with genitourinary symptoms. Little is known about the relationship between these exposures and the genitourinary health of older women, who tend to experience different and more prevalent genitourinary symptoms because of menopause and aging. OBJECTIVES: In this study, we examined relationships between common types of interpersonal trauma and aging-related genitourinary dysfunction among older women. STUDY DESIGN: We analyzed data from the National Social Life, Health, and Aging Project, a national area probability sample of older community-dwelling adults born between 1920 and 1947. We used cross-sectional data from home-based study visits conducted in 2005-2006 to examine interpersonal violence exposures (any lifetime sexual assault, past-year emotional and physical abuse), and past-year genitourinary symptoms (urinary incontinence, other urinary problems, and vaginal pain/lubrication problems with sexual intercourse) among women participants. Multivariable logistic regression models were used to relate interpersonal violence and genitourinary symptoms, adjusting for age, race/ethnicity, body mass index, education, marital status, parity, hormone therapy, depressive and anxiety symptoms, and self-reported health. In exploratory models, we further adjusted for vaginal maturation, a tissue-specific marker of aging-related urogenital atrophy obtained from vaginal self-swabs. RESULTS: In this national sample of 1551 older women (mean age 69 ± 2 years), 9% reported sexual assault, 23% reported emotional abuse, and <1% reported physical abuse. Urinary incontinence and other urinary problems were reported by 42% and 17%, respectively, and 42% of sexually active women (n = 527) reported vaginal symptoms with intercourse. In multivariable regression analyses adjusted for age, race/ethnicity, education, marital status, parity, hormone therapy, anxiety, depressive symptoms, and self-reported health, women with any lifetime history of sexual assault had 2.5 times the odds (95% confidence interval, 1.0-6.3) of vaginal symptoms, while women who reported past-year emotional abuse had higher odds of urinary incontinence (odds ratio, 1.7, 95% confidence interval, 1.2-2.4) and other urinary problems (odds ratio, 1.8, 95% confidence interval, 1.2-2.8). Among women who provided vaginal self-swabs (n = 869), adjustment for vaginal maturation-attenuated associations with other urinary problems (odds ratio, 1.6, 95% confidence interval, .9-2.6) and vaginal symptoms (odds ratio, 2.2, 95% confidence interval, 0.8-5.8). CONCLUSION: Sexual assault and emotional abuse may play a role in the development or experience of aging-related genitourinary dysfunction in older women. Clinicians caring for older women should recognize the prevalence and importance of traumatic exposures in health related to menopause and aging.

Sexual pain and IC/BPS in women.

Interstitial cystitis/bladder pain syndrome (IC/BPS) and female sexual dysfunction (FSD) are common conditions that substantially reduce women's health. In particular, women with IC/BPS show vulvodynia, a kind of FDS that originates from consistent pain around the vulvar area. There have been many studies attempting to find the underlying mechanisms that induce the chronic pain associated with IC/BPS and vulvodynia and explain why these two conditions often coexist. Proposed theories suggest that pain hypersensitivity is being mediated by peripheral and central sensitization. However, there are still many unknown factors, such as etiologies, that can evoke pain hypersensitivity and may be linking the casual relationship between IC/BPS and vulvodynia. At present, knowledge regarding IC/BPS and vulvodynia are insufficient when considering their clinical importance. Therefore, efforts are necessary to elucidate the issues surrounding IC/BPS and vulvodynia.

Tetrahydrocannabinol Reduces Hapten-Driven Mast Cell Accumulation and Persistent Tactile Sensitivity in Mouse Model of Allergen-Provoked Localized Vulvodynia.

Vulvodynia is a remarkably prevalent chronic pain condition of unknown etiology. An increase in numbers of vulvar mast cells often accompanies a clinical diagnosis of vulvodynia and a history of allergies amplifies the risk of developing this condition. We previously showed that repeated exposures to oxazolone dissolved in ethanol on the labiar skin of mice led to persistent genital sensitivity to pressure and a sustained increase in labiar mast cells. Here we sensitized female mice to the hapten dinitrofluorobenzene (DNFB) dissolved in saline on their flanks, and subsequently challenged them with the same hapten or saline vehicle alone for ten consecutive days either on labiar skin or in the vaginal canal. We evaluated tactile ano-genital sensitivity, and tissue inflammation at serial timepoints. DNFB-challenged mice developed significant, persistent tactile sensitivity. Allergic sites showed mast cell accumulation, infiltration of resident memory CD8+CD103+ T cells, early, localized increases in eosinophils and neutrophils, and sustained elevation of serum Immunoglobulin E (IgE). Therapeutic intra-vaginal administration of Δ9-tetrahydrocannabinol (THC) reduced mast cell accumulation and tactile sensitivity. Mast cell-targeted therapeutic strategies may therefore provide new ways to manage and treat vulvar pain potentially instigated by repeated allergenic exposures.

Vulvodynia in adolescents: presentation, diagnosis and treatment options.

PURPOSE OF REVIEW: Vulvodynia in adults is a significant source of genital and sexual pain with far reaching negative repercussions. Well designed studies with sufficient power in adults are limited and there are even fewer in adolescents. This review will help the clinician understand, diagnose and treat vulvodynia in adolescents based on current knowledge. RECENT FINDINGS: Although research on vulvodynia in adolescents is lacking, studies suggest that it not only exists but also may negatively impact an adolescent's medical and sexual health. This review will look at both historical approaches to vulvodynia, as well as more current approaches. It is important to note that no treatment modalities have been specifically approved for use in vulvodynia. SUMMARY: Vulvodynia in women is known to have significant impact on general health and sexual wellbeing. How early vulvodynia presents is unknown, but it appears that in at least some cases, it can be found in adolescents. Providers of adolescent care should have knowledge of this pain disorder so that they may appropriately diagnose and manage this multifactorial problem.

Heightened Pelvic Floor Muscle Tone and Altered Contractility in Women With Provoked Vestibulodynia.

BACKGROUND: Pelvic floor muscle (PFM) dysfunctions are reported to be involved in provoked vestibulodynia (PVD). Although heightened PFM tone has been suggested, the relative contribution of active and passive components of tone remains misunderstood. Likewise, alterations in PFM contractility have been scarcely studied. AIMS: To compare PFM tone, including the relative contribution of its active and passive components, and muscular contractility in women with PVD and asymptomatic controls. METHODS: Fifty-six asymptomatic women and 56 women with PVD participated in the study. The PVD diagnosis was confirmed by a gynecologist based on a standardized examination. OUTCOMES: PFM function was evaluated using a dynamometric speculum combined with surface electromyography (EMG). PFM general tone was evaluated in static conditions at different vaginal apertures and during repeated dynamic cyclic stretching. The active contribution of tone was characterized using the ratio between EMG in a static position and during stretching and the proportion of women presenting PFM activation during stretching. Contribution of the passive component was evaluated using resting forces, stiffness, and hysteresis in women sustaining a negligible EMG signal during stretching. PFM contractility, such as strength, speed of contraction, coordination, and endurance, also was assessed during voluntary isometric efforts. RESULTS: Greater PFM resting forces and stiffness were found in women with PVD compared with controls, indicating an increased general tone. An increased active component also was found in women with PVD because they presented a superior EMG ratio, and a larger proportion of them presented PFM activation during stretching. Higher passive properties also were found in women with PVD. Women with PVD also showed decreased strength, speed of contraction, coordination, and endurance compared with controls. CLINICAL IMPLICATIONS: Findings provide further evidence of the contribution of PFM alterations in the etiology of PVD. These alterations should be assessed to provide patient-centered targeted treatment options. STRENGTHS AND LIMITATIONS: The use of a validated tool investigating PFM alterations constitutes a strength of this study. However, the study design does not allow the determination of the sequence of events in which these muscle alterations occurred-before or after the onset of PVD. CONCLUSION: Findings support the involvement of active and passive components of PFM tone and an altered PFM contractility in women with PVD. Morin M, Binik YM, Bourbonnais D, et al.

Maintaining Affection Despite Pain: Daily Associations Between Physical Affection and Sexual and Relationship Well-Being in Women with Genito-Pelvic Pain.

Provoked vestibulodynia (PVD) is a recurrent, genito-pelvic pain condition that affects 8-12 % of women and has negative implications for sexual and relationship functioning. Many women with PVD report avoiding physical affection because they are concerned that affectionate behavior will lead to painful sexual activity. In community samples, physical affection is associated with improved sexual and relational well-being; however, no research has assessed the influence of physical affection on well-being in women with PVD. The current study examined day-to-day, within-person associations between affectionate behavior (hugging/kissing, cuddling) and sexual satisfaction, relationship satisfaction, sexual functioning, and pain intensity in women with PVD. Seventy women diagnosed with PVD completed an 8-week daily survey. Data were analyzed using multilevel modeling. All outcomes were assessed on days involving sexual activity (n = 401 days). Physical affection was assessed on days with and without sexual activity. Hugging/kissing was positively associated with sexual satisfaction, relationship satisfaction, and sexual functioning within any given day and when predicting the next day. Hugging/kissing was unrelated to pain intensity. Cuddling was not associated with any outcomes. Results persisted for affection that occurred on days with and without sexual activity. Findings suggest physical affection is beneficial for the sexual and relationship well-being of women with PVD. These results may inform interventions that encourage women coping with PVD to engage in more daily physical affection with their partners.

The aetiology of chronic vulval pain and entry dyspareunia: a retrospective review of 525 cases.

BACKGROUND: There are few published data about the incidence of diagnoses or treatment outcomes, for chronic vulval pain. AIMS: To document diagnoses and treatment outcomes in a cohort of chronic vulval pain presentations. MATERIALS AND METHODS: A retrospective case review of the patient database of a private vulval clinic between January 2011 and March 2015. RESULTS: Five hundred and twenty-five out of 3360 patients (15.6%) met the criterion of vulval pain alone. Mean age was 47.1 years (range 17-86). Average duration of symptoms was 60 months (range 3-432). Overall, 277/525 (52.7%) patients had satisfactory responses to appropriate treatment and 90/525 (17%) had partial improvement. A dermatosis was identified in 322/525 (61.3%) patients and of these, 211/322 (65.5%) had satisfactory responses to appropriate dermatological treatment. In the remaining 203/525 (38.7%) the skin was normal. These patients were questioned around the possibility of a neuromuscular cause for their pain, including pre-existing dysfunction, trauma or previous operations involving the spine, hips or lower limbs. There were 181/203 (89%) patients considered to have a neuromuscular cause for their pain and considered suitable for physiotherapy and/or neuromodulating medications. Of these patients, 63/182 (34.6%) had satisfactory responses to this treatment. One hundred and sixty-six out of 525 (31.6%) described vulval pain only during sexual intercourse. There was no statistically significant difference between different diagnoses and responses to treatment between patients reporting dyspareunia only and those sexually active women who did not experience dysparenunia (29/525, 5.5%). CONCLUSIONS: The majority of this cohort with chronic vulval pain had a dermatological disease with a smaller proportion caused by neuromuscular dysfunction. Both groups are potentially treatable.

Vulvodynia: What We Know and Where We Should Be Going.

OBJECTIVE: The aim of the study was to review the current nomenclature and literature examining microbiome cytokine, genomic, proteomic, and glycomic molecular biomarkers in identifying markers related to the understanding of the pathophysiology and diagnosis of vulvodynia (VVD). MATERIALS AND METHODS: Computerized searches of MEDLINE and PubMed were conducted focused on terminology, classification, and "omics" variations of VVD. Specific MESH terms used were VVD, vestibulodynia, metagenomics, vaginal fungi, cytokines, gene, protein, inflammation, glycomic, proteomic, secretomic, and genomic from 2001 to 2016. Using combined VVD and vestibulodynia MESH terms, 7 references were identified related to vaginal fungi, 15 to cytokines, 18 to gene, 43 to protein, 38 to inflammation, and 2 to genomic. References from identified publications were manually searched and cross-referenced to identify additional relevant articles. A narrative synthesis of the articles was conducted; however, meta-analysis was not conducted because of substantial heterogeneity in the studies and limited numbers of control-matched studies. RESULTS: Varying definitions of VVD complicate a meta-analysis, and standard definitions will better allow for comparisons of studies and enhance the applicability of evidence to patient populations. Although data are still limited, genomic and molecular diagnostic testings continue to be investigated as potential tools for the diagnosis of VVD. CONCLUSIONS: Standardized nomenclature will allow for comparability of studies and progress in research related to the pathophysiology of VVD and to facilitate clinical decision making and treatment choices. Although the current understanding of the pathogenesis of VVD is limited, there are new opportunities to explore potential diagnostic markers differences in women with VVD, which may lead to targeted therapy.

Effectiveness of Cognitive-Behavioral Therapy and Physical Therapy for Provoked Vestibulodynia: A Randomized Pilot Study.

INTRODUCTION: Non-medical and non-surgical treatments for provoked vestibulodynia target psychological, sexual, and pelvic floor muscle factors that maintain the condition. AIM: The goal of the study was to compare the effects of cognitive-behavioral therapy (CBT) and physical therapy (PT) on pain and psychosexual outcomes in women with provoked vestibulodynia. METHODS: In a clinical trial, 20 women with provoked vestibulodynia were randomly assigned to receive CBT or comprehensive PT. Participants were assessed before treatment, after treatment, and at 6-month follow-up by gynecologic examination, structured interviews, and standardized questionnaires measuring pain, psychological, and sexual variables. MAIN OUTCOME MEASURES: Outcome measurements were based on an adaptation of the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials recommendations. The primary outcome was change in intercourse pain intensity. Secondary outcomes included pain during the cotton swab test, pain with various sexual and non-sexual activities, and sexual functioning and negative pain cognitions. RESULTS: The two treatment groups demonstrated significant decreases in vulvar pain during sexual intercourse, with 70% and 80% of participants in the CBT and PT groups demonstrating a moderate clinically important decrease in pain (≥30%) after treatment. Participants in the two groups also had significant improvements in pain during the gynecologic examination, the percentage of painful intercourse attempts, the percentage of activities resulting in pain, and the ability to continue intercourse without stopping because of pain. Psychological outcomes, including pain catastrophizing and perceived control over pain, also showed improvement in the two groups. Significant improvements in sexual functioning were observed only in participants who completed CBT. Few between-group differences were identified other than the PT group showing earlier improvements in some outcomes. Nearly all improvements were maintained at the 6-month follow-up. CONCLUSION: The results of the study suggest that CBT and PT can lead to clinically meaningful improvements in pain and areas of psychosexual functioning.

Vestibulodynia: A Multifactorial Syndrome: A Case Report.

BACKGROUND: Vulvodynia is a difficult-to-treat, chronic, multifactorial malady that drastically lowers the quality of life of afflicted patients. CASE: A 68-year-old woman, who had been treated successfully for vulvodynia years before with medication, returned with a recurrence of vulvodynia symptoms that this time did not respond to treatment. She now had biopsy-confirmed lichen sclerosis and was found to have markedly elevated serum testosterone levels. An imaging study detected an ovarian lesion that, on removal, proved to be afibrothecoma. Postoperatively the testosterone rapidly dropped to normal levels. What was unexpected and unusual was that the vulvar pain disappeared and the lichen sclerosis markedly regressed. CONCLUSION: This case demonstrates a hormonal trigger for the development of vulvodynia.

Vulvodynia--An Evidence-Based Literature Review and Proposed Treatment Algorithm.

OBJECTIVE: We searched the medical literature from the last 15 years (1998 to 2013) relating to the etiology, diagnosis, and treatment of vulvodynia. The evidence was reviewed supporting the therapeutic proposals currently in use and propose the incorporation of novel, minimally invasive, interventional therapies, within the context of a multidisciplinary approach. METHODS: This was a systematic review of all relevant studies with no language restrictions. Studies were identified through Medline/PubMed (1998 to March 2013), the Cochrane Library (2001 to 2013), and conference records and book chapters. The keywords used included "chronic pelvic pain," "vulvodynia," "vestibulodynia," and search terms "etiology," "diagnosis," and "treatment" were added. The levels of evidence were assessed using grading system for "Therapy/Prevention/Etiology/Harm" developed by the Centre for Evidence-Based Medicine (CEBM). The grading system assists in clinical decision-making, and we decided to use "The Grading of Recommendations Assessment, Development, and Evaluation (GRADE)." RESULTS: A total of 391 papers were assessed. Of these, 215 were analyzed and 175 were excluded, as they pertained to areas not directly related to the disease under review. CONCLUSION: The optimal therapy for vulvar pain syndrome remains elusive, with low percentages of therapeutic success, using either local or systemic pharmacological approaches. Surgery involving invasive and often irreversible therapeutic procedures has resulted in success for certain subtypes of vulvodynia. We present a multidisciplinary approach whereby pain treatment units may provide an intermediate level of care between standard medical and surgical treatments.
