Does Degree of Vulvar Sensitivity Predict Vulvodynia Characteristics and Prognosis?

"Time is on my side". Disease trajectory of vulvodynia: a systematic review with a narrative synthesis

PURPOSE

The aim of this systematic review was to shed light on the disease-trajectory of vulvodynia and identify potential risk factors which may affect such trajectory.

METHODS

We searched Pubmed to identify articles providing evidence on vulvodynia trajectory (i.e., remission, relapse or persistence rates) with a minimum follow-up of 2 years. A narrative approach was used for data synthesis.

RESULTS

Four articles were included (total participants: 741 women with vulvodynia; 634 controls). At a 2-year follow-up, 50.6% of women reported remission, remission with relapse was observed in 39.7% and persistence throughout time occurred in 9.6%. A decrease in pain was observed in 71.1% of patients at a 7-year follow-up. Mean pain scores and depressive symptoms resulted lower at 2-year follow-up, whereas sexual function and satisfaction were increased. Factors associated with remission of vulvodynia were greater couple cohesion, decreased reporting of pain after intercourse and lower levels of worst pain. Risk factors for symptom persistence included marriage, more severe pain ratings, depression, pain with partner touch, interstitial cystitis, pain with oral sex, fibromyalgia, older age and anxiety. Recurrence was associated with: longer duration of pain, more severe ratings of the worst pain ever and pain described as provoked.

CONCLUSIONS

Symptoms of vulvodynia seem to improve over time, regardless of treatment. This finding contains a key message for patients and their physicians, considering the deleterious consequences of vulvodynia on women's lives.

Examining vaginal and vulvar health and sexual dysfunction in patients with interstitial cystitis (UNICORN-1 study)

INTRODUCTION AND HYPOTHESIS

The Vaginal Health Index Score (VHIS) and vulvodynia swab tests are used to assess vaginal health and vulvodynia. However, few studies have used these tests in patients with interstitial cystitis/bladder pain syndrome (IC/BPS). IC/BPS is a chronic, debilitating disorder, characterised by urinary frequency, urinary urgency and pelvic pain. It adversely affects organs adjacent to the urinary system, leading to complications of sexual dysfunction. This study was aimed at understanding sexual dysfunction in patients with IC/BPS, as well as deterioration of vaginal health and vulvodynia.

METHODS

This study compared the vaginal health of IC/BPS patients with that of asymptomatic control individuals. The Pain Urgency Frequency (PUF) score, Female Sexual Function Index (FSFI), VHIS, and vulvodynia swab tests, were used as tools. The PUF and FSFI are questionnaire-based surveys of bladder symptoms and sexual function respectively. VHIS evaluation and vulvodynia swab tests are performed by physicians. The PUF was used to assess baseline IC/BPS symptoms to validate the patient population, and FSFI, vulvodynia swab tests and VHIS were used to determine between-group differences.

RESULTS

Thirty-seven patients were recruited in each group. The IC/BPS group had a higher PUF score (18.19±3.51 vs 3.56±2.35; p<0.05), worse total FSFI (15.72±4.46 vs 26.3±4.93; p<0.05), and worse vulvodynia swab test and total VHIS (11.59±2.87 vs 22.05±3.05; p<0.05) scores than those of the control group.

CONCLUSIONS

Asian women with IC/BPS experienced greater sexual dysfunction, worsened vaginal health and increased vulvodynia compared with control individuals. Information on vaginal and vulva health is very useful in evaluating IC/BPS patients.

Managing vulvar and vestibular pain in postmenopausal women: recommendations from the Spanish Menopause Society, Sociedad Española de Ginecología y Obstetricia, Sociedad Española de Medicos de Atención Primaria y Federación Española de Sociedades de Sexología

Background: Relieving vulvar pain caused by atrophy in postmenopausal women is a challenge in our clinical practice. We know more and more about the vulva, its anatomy and physiology and we are realizing that it is different from the vagina. The importance of the vulvar approach in the management of vulvar or vestibular pain (VP) due to atrophy in postmenopausal women is becoming increasingly important. A panel of experts from several Spanish scientific societies (Spanish Menopause Society, AEEM; Spanish Federation of Sexology Societies, FESS; Spanish Society of Primary Care Physicians, SEMERGEN; and the Spanish Society of Gynecology and Obstetrics) held a meeting to discuss treatment recommendations for women with vulvar and VP based on the best available evidence, creating a report to describe grades of recommendations.

The Biopsychosocial Puzzle of Painful Sex

Genital pain associated with sex is a prevalent and distressing problem with a complex research and clinical profile. This article reviews the historical context of the "sexual pain disorders" and the circuitous trajectory that has led from the first mention of painful sex in ancient documents to the latest diagnostic category of genito-pelvic pain penetration disorder in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders as well as in other existing and proposed nomenclatures. Prominent etiologic research and emergent theoretical models are critically assessed, as is the latest treatment outcome research of note. Finally, the review points to a number of extant needs in the research and clinical effort, including an integrated biopsychosocial and multidisciplinary approach, randomized clinical trials, targeting of treatment barriers, and expansion of the entire enterprise to include populations that have not been considered. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 18 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

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.

Comparing Vestibule Examination Techniques: Light Touch, Serial Forces, and the Lidocaine Test

OBJECTIVE

The purpose of this study was to compare techniques and pain scales that assess tenderness in the vulvar vestibule in provoked vestibulodynia, using the cotton swab test and a vulvalgesiometer, and assess topical lidocaine solution with each.

MATERIALS AND METHODS

This randomized study at a specialty vulvar clinic evaluated tender vestibules of reproductive-aged women with vestibulodynia using light rolling cotton swab touch at 6 sites and evaluated the vulvalgesiometer at 2 sites, randomizing the order of the initial tool. Participants reported pain using the Numerical Rating Scale 0-10 and the Verbal Pain Scale 0-3. With the vulvalgesiometer, the pain tolerance threshold was measured using forces of 10, 25, 50, 100, 200, and 300 g. After both initial tests, lidocaine 4% topical solution was applied for 3 minutes, and the swab test and vulvalgesiometer were repeated in the order initially performed, constituting the lidocaine test. Data analysis used t tests, Fisher exact tests, Wilcoxon signed rank tests, and Spearman rank correlation.

RESULTS

Sixteen patients completed the study, 8 starting with each instrument. Light swab touch evoked significant pain, and lidocaine reduced pain to zero or mild levels. The pain threshold was 25 g, and only 38% could tolerate testing past 100 g without lidocaine. The Verbal Pain Scale correlated well with the Numerical Rating Scale.

CONCLUSIONS

Light rolling cotton swab touch using the 4-item verbal scale can map vestibulodynia tenderness that can be extinguished by lidocaine, consistent with distinguishing a mucosal condition. Forces by vulvalgesiometer of greater than 100-200 g may evoke pain other than mucosal allodynia.

Vulvodynia

Vulvodynia is a condition that occurs in 8-10% of women of all ages and is characterized by pain at the vulva that is present during sexual and/or non-sexual situations. Diagnosis is established through careful medical history and pelvic examination, including the cotton-swab test. The onset and maintenance of vulvodynia involves a complex interplay of peripheral and central pain mechanisms, pelvic floor muscle and autonomic dysfunction, anxiety, depression and childhood maltreatment as well as cognitive-affective, behavioural and interpersonal factors. Given the absence of empirically supported treatment guidelines, a stepwise approach of pelvic floor physical therapy and cognitive behavioural therapy as well as medical management is suggested, with surgery as the last option. Vulvodynia has a negative effect on the quality of life of women and their partners, and imposes a profound personal and societal economic burden. In addition, women with vulvodynia are more likely to report other chronic pain conditions, which further alters their quality of life. Future efforts should aim to increase girls', women's and healthcare professionals' education and awareness of vulvodynia, phenotype different subgroups of women based on biopsychosocial characteristics among more diverse samples, conduct longitudinal studies and improve clinical trial designs.

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.

Provoked vestibulodynia: current perspectives

Provoked vestibulodynia (PVD) refers to vulvar pain of at least 3 months duration, localized to the vestibule, provoked by touch and sexual activity and occurring in the absence of a clear identifiable cause. The clinical spectrum ranges from mild with distressing discomfort through to severe and disabling pain. Current understanding is that PVD is one of many chronic pain conditions characterized by sensitization of peripheral and central nociceptive pathways, with pain arising due to dysfunctional neuronal activity in the absence of painful stimuli. Pathophysiology is not well understood but is likely a complex interplay of environmental, genetic, psychological and immune factors. Care is multidisciplinary and follows general principles of chronic pain management with the addition of specific therapy tailored to address pelvic floor overactivity, and sexual and relationship difficulties. More recently, the therapeutic use of placebo is gaining traction in chronic pain research and is a very promising adjunctive therapy. The majority of women with PVD are managed outside of tertiary clinic settings, and care depends on availability and affordability of specialized services; however, much can be done by the primary health provider. PVD is common, and highly treatable, especially with early intervention, but unfortunately, many clinicians are unaware of this condition, and the biggest hurdle for women accessing treatment is obtaining a diagnosis. With treatment, most women can expect significant improvement, often with fairly simple interventions, although some women will benefit from referral to specialized centers. The aims of this article are twofold: firstly, to summarize current literature concerning PVD pathophysiology and management; secondly, to provide a framework for clinicians unfamiliar with vulvar medicine to understand and manage PVD.
