Outcomes of Temperature-Controlled Radiofrequency in Treating Vulvar Lichen Sclerosus: A Pilot Study

OBJECTIVE

This study aimed to evaluate the efficacy and safety of transcutaneous temperature-controlled radiofrequency (TTCRF) in the treatment of female vulvar lichen sclerosus (VLS).

METHODS

A retrospective analysis was conducted on VLS patients treated with TTCRF at our hospital between May 2021 and May 2023. Each patient underwent ten TTCRF sessions, spaced 1 week apart. Complications were monitored throughout the treatment, and efficacy was assessed using the Cattaneo scoring system and the Patient Global Impression of Change (PGI-C) questionnaire at 1 and 6 months Posttreatment.

RESULTS

A total of 40 patients were included in the study, with a mean age of 44.98 ± 11.14 years and a mean BMI of 22.78 ± 2.62 kg/m². Follow-up results at 1 and 6 months Posttreatment showed significant improvements in pruritus degree, skin elasticity, and skin color compared to baseline (p < 0.05), although no significant change in lesion scope was observed. According to the PGI-C questionnaire, 75% (30/40) of patients reported improvement or significant improvement at 1 month Posttreatment, which decreased to 60% (24/40) at 6 months. No adverse reactions were reported during the treatment or follow-up periods.

CONCLUSION

TTCRF is an effective and safe treatment for female VLS, offering significant short-term symptom relief. However, further research is needed to confirm long-term benefits.

2024 British Association for Sexual Health and HIV (BASHH) UK national guideline on the management of vulval conditions

BackgroundThe management of vulval disorders in Genitourinary Medicine (GUM) clinics requires targeted approaches due to the wide range of conditions affecting the vulva. Vulval diseases encompass various aetiologies, including dermatoses, pain syndromes, and pre-malignant conditions, necessitating specialized care often involving multidisciplinary collaboration.PurposeThis guideline aims to provide evidence-based recommendations for the diagnosis and management of specific vulval conditions that may present in GUM clinics. The focus is on conditions commonly managed by Genitourinary Physicians, either independently or in partnership with other specialists, depending on available local expertise. Additionally, guidance on onward referral is included to ensure optimal patient care.Study SampleThe guideline primarily addresses the management of individuals aged 16 years and older presenting to GUM clinics with non-infective vulval conditions.Data CollectionRecommendations within this guideline are derived from a review of existing literature, clinical expertise, and consensus among specialists. Emphasis is placed on diagnostic tests and treatment regimens tailored to the following conditions: Lichen sclerosus, Lichen planus, Eczema, Lichen simplex, Psoriasis, Vulval high-grade squamous intraepithelial lesions (previously vulval intraepithelial neoplasia), Vulval pain syndromes, and Non-sexually acquired acute genital ulceration (Ulcer of Lipschütz).ConclusionsThis guideline offers practical recommendations for the effective management of specific vulval disorders in GUM settings. It is not intended to be a comprehensive review of all vulval diseases but rather a focused resource to assist clinicians in providing high-quality, patient-centred care. Onward referral pathways are also outlined to support collaborative and multidisciplinary management of complex cases.

Internet-based treatment for provoked vulvodynia: factors associated with treatment outcomes

INTRODUCTION

Previous research has indicated that internet-based Acceptance and Commitment Therapy (ACT) can reduce pain during intercourse and increase pain acceptance in individuals with provoked vulvodynia, but the factors associated with treatment outcomes remain unknown.

AIM

This study aimed to investigate factors associated with changes in pain acceptance following an internet treatment based on ACT.

METHODS

This exploratory study used data from the EMBLA study, a multicenter randomized controlled trial that investigated the effects of internet-based ACT for provoked vulvodynia. The examined factors included sociodemographics, medical history, pain and sexual behavior, and psychosocial characteristics. Linear regression analysis was employed to assess the association of these factors with pain acceptance, including interaction effects. Results were adjusted for multiple testing using Bonferroni correction.

OUTCOMES

The outcome measure was pain acceptance assessed on the scale Chronic Pain Questionnaire-Revised, which comprises two sub-scales: activity engagement and pain willingness.

RESULTS

Before adjustment, greater improvement in overall pain acceptance and the subscale activity engagement was seen participants in the intervention group who had a history of physical violence or sexual assault. Increased time spent on the treatment platform per week was also associated with greater improvement in pain acceptance. Participants who reported gastrointestinal problems before the internet-based treatment showed better treatment outcomes in activity engagement. Previous contact with a psychologist or counselor was associated with less improvement in activity engagement. The intervention was less effective on the subscale pain willingness with increased age and for those reporting urinary problems. No associations remained statistically significant after adjustment for multiple testing.

CLINICAL IMPLICATIONS

Previous exposure to violence and sexual assault, concomitant gastrointestinal or urinary problems, and adherence to treatment should be further investigated in larger studies on factors associated with treatment outcomes after internet treatment based on ACT, especially regarding pain.

STRENGTHS AND LIMITATIONS

This was a novel and exploratory study and provides information for researchers in future investigations of how individual characteristics may influence treatment outcomes. A range of variables were explored in the models, underscoring the importance of future studies to strengthen the findings. One limitation concerns the sample size, which was fairly small considering the nature of the study.

CONCLUSION

After correcting for multiple testing, no factors were found to be statistically associated with changes in pain acceptance after the treatment.

Treatment strategies for erosive genital lichen planus: A systematic review of therapeutic modalities and emerging breakthroughs

Background and Aims

Erosive genital lichen planus (EGLP) is a severe form of lichen planus characterized by painful erosions in the genital area, leading to significant distress and complications. This review aims to provide a thorough examination of EGLP, focusing on its clinical manifestations, diagnostic challenges, and various treatment strategies, with an emphasis on patient-centered care.

Methods

Adhering to PRISMA guidelines, we conducted a systematic review of 26 studies that explored dermatological treatments for EGLP. Our literature search was comprehensive, covering PubMed, Scopus, and Web of Science. Data were extracted systematically using established tools to ensure a robust analysis of the treatment modalities.

Results

EGLP presents with a range of symptoms, including severe pain, itching, and sexual dysfunction. Treatment options include topical corticosteroids, systemic medications, and surgical interventions. Despite the availability of various therapies, many cases are refractory to treatment, resulting in chronic symptoms and reduced quality of life. Emerging therapies show promise but are not yet established as standard practice.

Conclusion

Management of EGLP requires a tailored, multidimensional approach. While topical corticosteroids remain essential, the development of new therapies offers hope for improved outcomes. A patient-centered approach is vital to address both the physical and psychosocial impacts of EGLP. Continued research is necessary to refine treatment protocols and enhance patient care.

A Mimicker of Differentiated Vulvar Intraepithelial Neoplasia: Reactive Atypia From Noncompliance With Lichen Sclerosus Therapy

ABSTRACT

Differentiated vulvar intraepithelial neoplasia (d-VIN) is an HPV-independent precursor to vulvar squamous cell carcinoma. The histology of d-VIN lesions is difficult to differentiate from that of non-neoplastic epithelial disorders, especially lichen sclerosus (LS). The authors present a case of LS, where relying on histopathology alone could have led to misdiagnosis. The patient was a 17-year-old female patient with clinical features of vulvar dermatitis and LS for 2 years. She was counseled to apply clobetasol 0.05% to the affected area daily but reported no improvement after 6 months. A biopsy of the right labia majora revealed histologic findings typical of d-VIN and near-contiguous p53 expression. These features are characteristic of d-VIN. However, d-VIN is exceedingly rare in young patients. The case was reviewed by 6 dermatopathologists and gynecologic pathologists, who observed that the degree of inflammation would be unusual postclobetasol therapy and could be due to noncompliance. A review of the patient's chart revealed that she "does not always remember to apply" clobetasol. The patient's clinician confirmed that there were compliance issues, and the follow-up biopsy was negative for d-VIN. The case was signed out as LS, with a note describing the above, and to rebiopsy if concern persisted. The authors conjecture that inflammatory infiltrates in the biopsied area caused reactive atypia due to lack of adherence to treatment. Although the patient's age helped rule out d-VIN, similar cases in elderly patients may be occurring. Pathologists must be aware that reactive forms of untreated LS can mimic d-VIN, to avoid misdiagnosis.

Unmet needs in treating itch: reaching beyond eczema

PURPOSE

Pruritus is an unpleasant sensation that creates the urge to scratch. In many chronic conditions, relentless pruritus and scratching perpetuates a vicious itch-scratch cycle. Uncontrolled itch can detrimentally affect quality of life and may lead to sleep disturbance, impaired concentration, financial burden, and psychological suffering. Recent strides have been made to develop guidelines and investigate new therapies to treat some of the most common severely pruritic conditions, however, a large group of diseases remains underrecognized and undertreated. The purpose of this article is to provide a comprehensive review of the challenges hindering the treatment of pruritus.

METHODS

An online search was performed using PubMed, Web of Science, Google Scholar, and ClinicalTrials.gov from 1994 to 2024. Included studies were summarized and assessed for quality and relevance in treating pruritus.

RESULTS

Several barriers to treating pruritus emerged, including variable presentation, objective measurement of itch, and identifying therapeutic targets. Itch associated with autoimmune conditions, connective tissue diseases, genodermatoses, cutaneous T-cell lymphoma, and pruritus of unknown origin were among the etiologies with the greatest unmet needs.

CONCLUSION

Treating pruritus poses many challenges and there are many itchy conditions that have no yet been addressed. There is an urgent need for large-scale controlled studies to investigate potential targets for these conditions and novel therapies.

Vulvar Lichen Sclerosus: Navigating Sex Hormone Dynamics and Pioneering Personalized Treatment Paradigm

Vulvar lichen sclerosus (VLS) is a frequently overlooked inflammatory disorder affecting the skin and mucous membranes of the vulva. With a propensity for atrophy, severe scarring, functional impairment, and malignant evolution, VLS is a disease that recurs frequently; early diagnosis, rapid treatment, and ongoing patient follow-up are essential. Potent topical corticosteroids (TCSs) are now widely recognized as the most effective treatment for achieving remission in VLS, but considering the potential complications of long-term treatment with potent TCSs, understanding the evolution of VLS during puberty becomes particularly crucial in determining the necessity for aggressive or more conservative therapeutic interventions. Emerging treatments, including PRP (platelet-rich plasma), stem cell therapy, and energy-based lasers like fractional CO2 and Nd-YAG, are being investigated to identify more effective VLS treatments than ultrapotent topical corticosteroids. However, more research is needed to assess the efficacy and safety of these new medicines. Topical clobetasol 0.05% ointment daily for 4-12 weeks is the gold standard for treating VLS. This article is a narrative review of the English-language medical literature from 2017 to November 2023, following three main sections concerning VLS: studies of the evolution amid pubertal hormonal changes; studies of the outcomes of personalized conventional therapies; and studies addressing the spectrum of innovative modalities for VLS.

Effectiveness of topical gabapentin in the treatment of vulvodynia: a narrative synthesis

Vulvodynia is a leading cause of dyspareunia in premenopausal women, causing considerable morbidity and sexual dysfunction. A multimodal approach is used to treat vulvodynia. Alongside psychosocial interventions and physiotherapy, pharmacological treatment such as oral gabapentin are used in the treatment of vulvodynia. Topical formulations of gabapentin have shown promise in animal models and case reports investigating its use in other pain conditions. The topical route also avoids the systemic complications of gabapentin such as somnolence, dizziness, and peripheral edema. This study aimed to perform a narrative synthesis of studies investigating the use of topical gabapentin in the treatment of vulvodynia. The primary outcome was a change in pain score following treatment with topical gabapentin. A broad literature search was performed, which identified four studies for inclusion. The included studies reported improved pain measures following treatment; however, conclusions cannot be made due to methodological heterogeneity and inherent limitations. These include lack of control arms, small sample sizes, lack of patient randomization, and use of combination treatments. Due to the paucity of evidence, this review supports the future implementation of double-blind randomized controlled trials to further investigate the efficacy of topical gabapentin in the treatment of vulvodynia.

A systematic review of sexual health consequences among women with lichen sclerosus

Introduction

Lichen sclerosus (LS) is a chronic inflammatory skin condition predominantly affecting the vulva. Studies have shown high rates of sexual dysfunction in patients with LS; however, the sexual effects of the condition are poorly acknowledged.

Objectives

We sought to identify sexual health consequences among women with vulvar LS through systematic review of available literature.

Methods

A systematic review of the literature was conducted to find reports on sexual health consequences among women with LS. PubMed, MEDLINE, and Scopus were queried. Included articles were observational studies evaluating women with LS and their sexual health and randomized controlled trials or comparative studies utilizing a validated sexual health measure before intervention among the same population. Articles must have been written in English and published from January 1991 to April 2022.

Results

The search produced 683 references, including 32 articles that met criteria for full-text review and 20 reported studies that met inclusion criteria. Two studies investigated the impact of LS on interpersonal relationships, 6 studies evaluated sexual symptoms, 16%-60% reported sexual dysfunction, and 22%-56.7% reported dyspareunia. Also described were decreased sexual frequency and satisfaction, negative impact on sexual relationships, and feelings of inadequacy. Eight publications evaluated the Female Sexual Function Index (FSFI); all described studies that demonstrated a central tendency less than 26.55. Four publications evaluated the Female Sexual Distress Scale (FSDS); all demonstrated average scores greater than 12. Two publications evaluated the Female Genital Self-Image Scale (FGSIS), both found decreased scores compared to controls. Four publications evaluated the Dermatology Life Quality Index (DLQI); impact on quality of life was small to very large, with sexual difficulties affecting most study patients. One publication evaluated the Vulvar Quality of Life Index (VQLI); sexuality was the second highest-scoring subgroup.

Conclusions

Sexual health consequences of LS include sexual pain, dysfunction, and distress; negative genital self-image; and negative impact on sexual relationships. Women with LS experience a negative impact on quality of life, particularly related to sexual functioning.

Quality of life impact and treatment response in vulval disease: Comparison of 3 common conditions using the Vulval Quality of Life Index

BACKGROUND/OBJECTIVES

To compare the quality of life in patients with vulval lichen sclerosus (VLS), vulval lichen planus (VLP) and chronic vulvovaginal candidiasis (CVVC), as measured by the Vulval Quality of Life Index (VQLI).

METHODS

A retrospective, single-centre cohort study was conducted at a combined dermatology and gynaecology practice from March 2018 to November 2021. VQLI scores and patient data were systematically collected and recorded in an online patient database. Treatment regimens were individualised and titrated to clinical response.

RESULTS

Over 3 years, a total of 200 women were recruited: 59 with CVVC, 79 with VLP and 62 with VLS. The median duration of follow-up for all patients was 45.43 (16.25-80.89) weeks. At baseline, the median (interquartile range [IQR]) VQLI score was 24.00 (19.00-31.00), 21.00 (12.00-26.00) and 14.00 (7.00-26.00) for CVVC, VLP and VLS, respectively. At follow-up, the median (IQR) VQLI score for CVVC, VLP and VLS was 9.00 (3.00-15.00), 9.00 (3.00-16.00) and 5.00 (2.00-10.00), respectively. All three groups showed a significant improvement in VQLI score (p < 0.0001). At baseline, the highest scoring domains were 'Sexual Function' for CVVC and 'Future Health Concerns' for VLP and VLS. At follow-up, the highest scoring domains were 'Sexual Function' for CVVC and VLP, and 'Future Health Concerns' for VLS.

CONCLUSIONS AND RELEVANCE

Vulval disease has an immense impact on QOL, especially in patients with CVVC. The VQLI is useful to clinicians in identifying the unique impact of each vulval condition on a patient's QOL in order to provide better patient-focussed care.

Vulvar High-Grade Squamous Intraepithelial Lesions Treated with Imiquimod: Can Persistence of Human Papillomavirus Predict Recurrence?

Simple Summary

Vulvar high-grade intraepithelial lesion (vulvar HSIL) is a premalignant vulvar condition that requires intervention, usually surgery. It recurs frequently, and its treatment involves repeated disfiguring surgeries. Vulvar HSIL is associated with human papillomavirus. Imiquimod is a medical treatment option currently attracting attention because vulvar high-grade intraepithelial neoplasia is frequent in young women with multiple vulvar lesions. Few studies have evaluated the long-term effects of the response to imiquimod and the association of human papillomavirus with response and recurrence. We describe a retrospective (with cases already treated) study designed to determine the long-term response to imiquimod in patients with vulvar HSIL, and also to analyze the role of human papillomavirus (HPV), and different HPV types, in the persistence or recurrence of vulvar HSIL after imiquimod treatment.

Abstract

Objectives: Vulvar high-grade squamous intraepithelial lesion (vulvar HSIL) or vulvar intraepithelial neoplasia (VIN) is a premalignant condition that can progress to carcinoma. Imiquimod is a topical drug with high effectiveness and low morbidity. We aimed (1) to assess the long-term response to imiquimod in a cohort of patients with vulvar HSIL and (2) and to analyze the role of HPV determined in pre- and post-imiquimod treatment biopsies in the persistence or recurrence of vulvar HSIL. Design: Retrospective study between 2011 and 2022. Setting: Referrals from the primary care area of Baix Llobregat treated in the gynecology department of a university hospital in Barcelona, Spain. Population: 20 women with vulvar HSIL treated with imiquimod. Methods: The inclusion criteria were vulvar HSIL, vulvar HPV determination by pre- and post-treatment biopsy, acceptance of medical treatment, at least one follow-up and 4 weeks of treatment. Main outcome measures: Histological diagnosis of vulvar HSIL with pre- and post-imiquimod HPV determination. Response to treatment (complete, partial, no response, recurrence). Results: After imiquimod, 10 (50%) and 6 (30%) cases had complete and partial responses, respectively. Another 4 cases (20%) did not respond. Before treatment, 19 (95%) cases were positive for vulvar HPV (16 cases had HPV type 16). After treatment, 10 cases (50%) were positive for HPV (8 cases with HPV type 16): 2 cases (20%) with a complete response, 5 cases (83.3%) with a partial response and 3 cases (75%) with no response. Eight of the 10 HPV-negative cases (80%) post-treatment showed a complete response. HPV type 16 was present in 16 cases (84.2%) pre-treatment and in 8 cases (80%) post-treatment. Ten patients underwent additional treatments following a partial response, no response or recurrence. The 2 HIV and 3 immunosuppressed patients treated with imiquimod showed a partial response and required additional treatment. All these patients were HPV-positive pre- and post-treatment (100%). Response to imiquimod was associated with post-treatment vulvar HPV positivity (p = 0.03). The median time to a complete response in HPV-negative cases was 4.7 months versus 11.5 months in HPV-positive cases post-imiquimod treatment. Recurrence of vulvar HSIL was observed in 7 patients (35%), with a median time to recurrence of 19.7 months (range 3.2–32.7). Recurrence was experienced in 10% of cases with a complete response, in 4/6 (66.6%) cases with a partial response, and in 2/4 (50%) women with no response. Four of the 7 recurrent cases (57%) were infected with HIV or immunosuppressed. Six (85%) of the recurrent cases were HPV-positive post-treatment (all were HPV type 16). Four (30.7%) of the non-recurrent cases were HPV-positive post-treatment with imiquimod (p = 0.05), two of which were HPV type 16 (50%). Conclusions: Imiquimod effectively treats vulvar HSIL. Cases with a complete response showed less HPV positivity post-treatment than partial or non-response cases. Recurrences were more frequent in those with a partial or no response to imiquimod, and in immunosuppressed patients. In recurrent cases, 85% were HPV-positive post-treatment, while 30.7% of non-recurrent cases were HPV-positive. HPV positivity in the post-treatment biopsy suggests the need for stricter follow-up of patients.

Clinical study on multi-focused laser in the treatment of vulvar lichen sclerosus

Objective

To investigate the clinical effect of Multi-focused (MF) laser in the treatment of vulvar lichen sclerosus (VLS).

Methods

In this single-center, randomized controlled trial, we compared the effect of fractionated MF laser with other treatments on patients with biopsy-proven VLS. Patients with VLS were enrolled in this study and randomly divided into three groups. Patients in the experimental group were treated with a CO2 laser, control group 1 was treated with radiofrequency, and control group 2 was treated topically with glucocorticoids and soaking with Chinese patent medicine. The pruritus degree, skin elasticity, skin color, lesion scope, and total score were compared before treatment, at one month after treatment, and three months after treatment.

Results

One month after treatment, the pruritus degree, skin elasticity, skin color, lesion scope, and total score decreased in the experimental group, and the differences were statistically significant (P &lt; 0.05). In control group 1, the differences in pruritus degree, skin color, and total score were statistically significant (P &lt; 0.05), but the differences in skin elasticity and lesion scope were not statistically significant (P &gt; 0.05). In control group 2, the differences in pruritus degree and total score were statistically significant (P &lt; 0.05), but the differences in skin elasticity, skin color, and lesion scope were not statistically significant (P &gt; 0.05). At one month after the end of treatment, the differences in pruritus degree, skin elasticity, skin color, lesion scope, and total score among the three groups were not statistically significant. At three months after the end of treatment, the differences in the scores of the five indicators were statistically significant.

Conclusion

For the three treatment methods for VLS, topical corticosteroids + traditional Chinese medicine can quickly relieve itching symptoms in patients, but it cannot significantly improve skin elasticity, skin color, and lesion scope, and VLS easily relapses after treatment. Radiofrequency can improve itching symptoms and skin color but has poor effects on the change of skin elasticity and lesion scope. Multi-focused laser treatment can alleviate the degree of pruritus, improve skin color and elasticity, and narrow the lesion scope, and VLS will not relapse within three months after treatment.

Vulvar dermatoses: a cross-sectional 5-year study. Experience in a specialized vulvar unit

Background

Vulvar diseases are common in the general population and have a negative impact on the quality of life.

Objectives

To describe our experience as dermatologists in the management of vulvar dermatosis consultations.

Methods

A retrospective observational study was conducted with patients who attended monographic vulvar consultations over a 5-year period. Clinical information was obtained from the patient’s charts.

Results

148 women were studied. Their mean age was 43.24 years (standard deviation: 15.15 years), with ages ranging from 4 months to 80 years. 53.4% of patients took between 2 and 5 years to seek medical attention for the first time. The most frequent diagnosis was lichen sclerosus (41.9%), irritative eczema of the vulva (14.9%), and lichen simplex chronicus (10.1%). 83.8% reported anogenital itching, 66.2% pain, and 45.9% dyspareunia. The most frequently prescribed treatment was ultra-potent topical corticosteroids (clobetasol propionate; 41.2%). Patients with lichen sclerosus were significantly older than those who presented with any of the other diseases. No differences were found in terms of either the time of disease evolution or in symptom presentation.

Study limitations

Retrospective study. Vulvar diseases with an infectious cause are usually managed in primary care, therefore, were not included. All patients were recruited from a single private hospital which limits the comparisons with the public health system.

Conclusions

Vulvar diseases frequently occur and are associated with high morbidity. It is essential to promote the development of specific vulvar consultations in hospitals. Specialties such as dermatology, gynecology, urology, or physiotherapy must be part of these units.

Compliance with the Updated BASHH Recurrent Vulvovaginal Candidiasis Guidelines Improves Patient Outcomes

Recurrent vulvovaginal candidiasis (RVVC) is a debilitating, chronic condition that affects over 138 million (6%) women of reproductive age annually. We performed a retrospective audit of RVVC referrals to our tertiary care Candida clinic to evaluate the impact of the significantly updated British Association of Sexual Health and HIV (BASHH) 2019 vulvovaginal candidiasis guidelines on patient outcomes, the principles of which were implemented at our centre at the onset of the guideline revision process in 2017. A total of 78 women referred with suspected RVVC in 2017–2020 were included. Their mean symptom duration prior to referral was 6.7 years. RVVC was the definitive diagnosis in 73% of cases. In the 27% of patients without RVVC, the most common diagnoses were acute VVC (29%), vulval eczema (14%), dry skin (14%) and vulvodynia (10%). Of those with RVVC, 60% were diagnosed with an additional diagnosis, most commonly vulval eczema or vulvodynia. Only 12% of women had been counselled on appropriate vulval skin care, the mainstay of RVVC management. Long-term antifungal suppression was initiated in 68% of women. Azole-resistant Candida, for which there is no licensed treatment available in the UK, was identified in 23% of women with RVVC. In the follow-up, 82% of patients reported good control of symptoms using antifungal suppression therapy and recommended skin care, 16% had partial symptom control with some “flare-ups” responding to treatment, none reported poor control and for 2% this information was not available. RVVC-related morbidity can be reduced by following the principles outlined in the BASHH guidelines.

The Impact of Psychosexual Counseling in Women With Lichen Sclerosus: A Randomized Controlled Trial

INTRODUCTION

Lichen sclerosus (LS) can affect sexuality and quality of life (QoL).

OBJECTIVE

The aim of the study was to evaluate the impact of psychosexual counseling in women with LS.

MATERIALS AND METHODS

One hundred fifty-eight women 18 years or older, newly diagnosed with LS, and referred to North Denmark Regional Hospital from January 2018 to November 2019 were included. The women were randomized in a 1:1 ratio to usual care or an intervention group receiving usual care and up to 8 individual consultations with a specialist in sexual counseling. Spouses or partners were encouraged to participate. The women filled out the questionnaires Female Sexual Function Index (FSFI), Dermatology Life Quality Index, and the WHO-5 Well-Being Index at baseline and after 6 months.

RESULTS

The controls presented a mean score of 14.8 ± 8.7 and the intervention group presented a mean score of 12.8 ± 8.9 at FSFI. At follow-up, the controls had an FSFI score of 15.2 ± 9.2 and the intervention group revealed an FSFI score of 18.3 ± 9.5. Both groups experienced improved sexual functioning and for the intervention group the increase was significant ( p < .001).At baseline, the Dermatology Life Quality Index mean score was 8.9 ± 5.6 for the control group and 9.3 ± 6.1 for the intervention group. At follow-up, the controls revealed a score of 8.6 ± 5.5 and the intervention group a score of 6.8 ± 5.8. The intervention group reached a significantly higher degree of QoL than the controls ( p = .008).

CONCLUSIONS

Psychosexual counseling has a significant impact on sexual functioning and QoL in women with LS.

Vulvodynia: What is available online? A systematic review of information on the internet

AIM

This review aimed to evaluate the quality of medicalinformation online for patients relating to vulvodynia. To our knowledge no evaluation of online patient information exists regarding vulvodynia and, at present, there is no standardized or validated method of evaluating medical information on the internet.

METHODS

A clearly defined protocol was developed to generate keywords relating to vulvodynia. The three most popular search engines worldwide; google.com, yahoo.com, and bing.com, were searched in September 2020. Three assessors evaluated eligible webpages for accuracy, credibility, readability, and reliability.

RESULTS

Forty-five webpages were eligible with 38% given HON certification or Information Standard approval. Only one webpage achieved a DISCERN score of ≥63 indicating excellent reliability. No webpages scored a maximum 10 points for credibility. Eleven percent of webpages were rated "accurate" with score 17 or above. The modal Flesch Kincaid Grade Level was 9 with only 15.6% having a readability grade level of 8 or less.

CONCLUSIONS

It has been shown in previous studies that patient information available online pertaining to gynecological conditions is frequently inaccurate, with limited regulation and low reliability, and our findings are in agreement with this. As patients increasingly look to the internet for medical information and education, we as clinicians, need to ensure the resources available are of a high standard and regulated. Without ensuring safe and effective healthcare resources, we risk misinformation which can negatively impact clinical care.

Internet-based Treatment for Vulvodynia (EMBLA) - A Randomized Controlled Study

BACKGROUND

Internet-based ACT (Acceptance and commitment therapy) treatment may improve accessibility and reduce stigma related to seeking health care, but there are a lack of studies investigating internet-based treatment using ACT principles for women with vulvodynia.

AIM

The aim of this study was to investigate the effects of an internet-based treatment of pain during intercourse for women with provoked vulvodynia compared with no intervention during the waiting period before clinical treatment.

METHODS

A multicenter randomized controlled trial was conducted during 2016 to 2020, in which 99 participants were included. Participants were randomized to either a 6 week guided internet-based treatment using ACT principles or usual care. Data were collected at baseline, 6 weeks after baseline, and approximately 10 months after baseline.

OUTCOMES

Pain-related (pain during intercourse, tampon test, impact of pain on sexual function) and pain behavior-related outcomes (attempts at intercourse, sexual activities besides intercourse, willingness to perform the tampon test, chronic pain acceptance questionnaire) were used as outcomes.

RESULTS

Treatment was efficacious in what concerns pain during intercourse and pain acceptance. Less pain during intercourse among women in the intervention group was observed at both post-treatment (primary endpoint, P = .01, Cohen's d = 1.4, 95% CI = 0.33, 2.4), and follow-up (P = .04). Absolut mean difference between groups for pain during intercourse at post-treatment was -2.84, (95 % CI = -4.91, -0.78), and -1.58 at follow-up, (95 % CI = -3.17, 0.02), where the intervention group rated less pain than controls. No differences between groups over time were found for tampon test measures or impact of pain on sexual function. There was a significant difference between groups at all timepoints indicating fewer attempts at intercourse among participants in the intervention group. At post-treatment, women who underwent internet-based treatment reported higher pain acceptance and a rise in activity engagement compared with the control group.

CLINICAL IMPLICATIONS

There is an indication that internet-based treatment could be incorporated into clinical practice as a complement to clinical treatment.

STRENGTHS & LIMITATIONS

Study strengths included using several forms of recruitment and an intervention built by different professions with long experience of treating patients with vulvodynia. High dropout rate was a limitation of this study.

CONCLUSION

Internet-based treatment may have an impact on pain during intercourse and positive effects on pain acceptance. However, conclusions must be drawn with caution due to the small sample size.

Comparing the Effects of Two Cream Formulations, Henna (Lawsonia inermis) and Clotrimazole, on Vaginal Candidiasis: A Randomized Controlled Trial

Background: Vaginal candidiasis is the most prevalent infection among reproductive-aged women. The current treatment for this disorder includes azole compounds. Objectives: The aim of this study was to compare the effects of two creams, henna (Lawsonia inermis) and clotrimazole, on vaginal candidiasis. Methods: In this trial, 80 women with vaginal candidiasis were recruited and randomly assigned into two groups to receive either henna (n = 40) or clotrimazole (n = 40) for one week. The ethanol extract of henna was prepared. Vaginal discharge was cultured, and vaginal pH, colony formation, lactobacillus formation, and vaginitis subjective symptoms were evaluated before and one, two, and four weeks after the intervention. The chi-square test, independent t-test, and Generalized Estimating Equations were were used for analyzing the data using SPSS version 22. Results: After four weeks of the intervention, almost 90% of the women in the henna group declared no burning sensation, itching, discharge, irritation, or dyspareunia, while only 45%, 5%, 37.5%, 52.5%, and 27.5% of the participants in the clotrimazole group did not have these symptoms, respectively (P < 0.001). The means (SD) of colony formation were 290.85 (47.35) and 265.12 (37.46) in the henna and clotrimazole groups, respectively, at the baseline, which reduced to zero and 25.45 (25.09) in the 4th week of the intervention (P = 0.001). Compared with the clotrimazole group, there was a significant increase in the mean of lactobacillus formation and a significant decrease in vaginal pH in the henna group (P < 0.001). Conclusions: Henna vaginal cream could significantly reduce the symptoms of vaginal candidiasis, such as burning sensation, itching, discharge, irritation, and dyspareunia. Also, it could decrease colony formation and vaginal pH and increase lactobacillus formation.

Management of Vulvar Cancer Precursors: A Survey of the International Society for the Study of Vulvovaginal Disease

OBJECTIVE

The aim of the study was to determine how experts treat vulvar high-grade squamous intraepithelial neoplasia (VHSIL) and differentiated vulvar intraepithelial neoplasia (dVIN).

METHOD

A 26-question survey was designed through a literature review, reviewed by the Survey Committee of the International Society for the Study of Vulvovaginal Disease (ISSVD), and distributed to all ISSVD members via e-mail in January 2019.

RESULTS

Overall, 90 of 441 physician members consented to participate and 78 of 90 were eligible to complete the survey. Most respondents were gynecologists (77%), followed by dermatologists (12%). Forty-five percent responded that their pathology was being reported using the 2015 ISSVD terminology of vulvar squamous intraepithelial lesions. The most common first-line treatments were as follows: unifocal VHSIL-excision (65%), multifocal VHSIL-imiquimod 5% (45%), VHSIL in a hair-bearing area-excision (69%), and clitoral disease-imiquimod 5% (47%). In the recurrent VHSIL, excision was favored (28%), followed by imiquimod 5% (26%) and laser (19%). Differentiated vulvar intraepithelial neoplasia was most often first treated with excision (82%), and more patients were referred to gynecologic oncology. Most patients were seen in follow-up at 3 months (range: 1 week-6 months). Sixty-seven respondents provided 26 different ways to follow treated patients, which were most commonly every 6 months for 2 years and then yearly (25%), followed by every 6 months indefinitely (18%).

CONCLUSIONS

Treatment of VHSIL and dVIN varies among vulvar experts with excision being the most common treatment, except in multifocal VHSIL where imiquimod is commonly used. There is wide variation in how patients are followed after treatment.

The Quality of Life and Sexuality in Women with Lichen Sclerosus - A Cross Sectional Study

BACKGROUND

Lichen sclerosus (LS) affects the female anogenital area, causing anatomical changes. Reported symptoms include itching, soreness and dyspareunia.

OBJECTIVE

This cross-sectional study intends to evaluate the quality of life and sexual functioning in women with LS.

METHODS

158 women aged over 18, diagnosed with LS, and referred to North Denmark Regional Hospital from January 2018 to November 2019 were included. The questionnaires 'Female Sexual Function Index (FSFI)', 'Dermatology Life Quality Index (DLQI)', and the 'WHO-5 Well-Being Index' were completed.

RESULTS

The women (mean age 47 years (18-76)) presented a low score on all FSFI scales, with a mean score of 13.83 (95% CI: 12.46;15.20), indicating reduced sexual functioning. The sub-group evaluation scored as follows: Desire 2.32; arousal 2.23; lubrication 2.39; orgasm 2.28; satisfaction 3.02; pain 1.59. The results from DLQI revealed a mean score of 7.88 (95% CI: 7.02;8.74), indicating a moderate effect on the women´s everyday life. The mean sub-scores were: Treatment 0.32; sexual difficulties 1.56; relations 1.02; work/study 0.34; sport 0.45; social activities 0.54; clothing 0.89; shopping 0.22; embarrassment 0.99 and itching, soreness and, pain 1.55. The mean score for the WHO-5 Well-Being Index was 56.66 (95% CI: 53.48;59.84) indicating that 40% of the women had signs of depression.

CONCLUSIONS

This study concludes that LS has a considerable influence on the sexual functioning and quality of life of women. Health care professionals must not only consider the biological aspects but also the psychological and social aspects.

Human beta defensin levels and vaginal microbiome composition in post-menopausal women diagnosed with lichen sclerosus

Human beta defensins (hBDs) may play an important role in the progression of lichen sclerosus (LS), due to their ability to induce excessive stimulation of extracellular matrix synthesis and fibroblast activation. The genetic ability of the individual to produce defensins, the presence of microbes influencing defensin production, and the sensitivity of microbes to defensins together regulate the formation of an ever-changing balance between defensin levels and microbiome composition. We investigated the potential differences in postmenopausal vaginal microbiome composition and vaginal hBD levels in LS patients compared to non-LS controls. LS patients exhibited significantly lower levels of hBD1 (p = 0.0003), and significantly higher levels of hBD2 (p = 0.0359) and hBD3 (p = 0.0002), compared to the control group. The microbiome of the LS patients was dominated by possibly harmful bacteria including Lactobacillus iners, Streptococcus anginosus or Gardnerella vaginalis known to initiate direct or indirect damage by increasing defensin level production. Our observations highlight that correcting the composition of the microbiome may be applicable in supplementary LS therapy by targeting the restoration of the beneficial flora that does not increase hBD2-3 production.

Real-World Practices and Attitudes Towards Intimate Self- Care: Results From An International Women's Survey

OBJECTIVE

Vulvovaginal health is important to women's overall health, fertility, sexuality, self-perception, self-confidence and intimacy. It is important to identify the existing perceptions and levels of knowledge about intimate care practices from women in different countries, and with different cultures, religions, and perspectives to help women overcome barriers to optimal intimate care.

METHODS

An anonymous online survey about general and intimate hygiene routines/habits was distributed across 10 countries (England, France, Germany, Italy, Portugal, Russia, China, Philippines, Taiwan, Thailand). The sample consisted of around 10,000 women (aged 18 to 60 years) recruited through an online panel.

RESULTS

The survey indicates that for many women, cleaning the intimate area is not just about hygiene, but also about taking care of themselves. Intimate care practices, performed daily, varies widely among the countries (from 38% to 91%). Italy, Philippines Portugal, Russia and Thailand were the countries with higher percentage. Intimate care is mainly associated with hygiene and health benefit, but interestingly women engage in intimate care more often with age. Most women worldwide are comfortable talking about female genitalia but still consider it a taboo topic, particularly among younger generations. Asian countries continue to carry negative connotations.

CONCLUSIONS

This survey is the first of its kind for number of women involved in this research and for multi-cultural design. Women perceive that practicing intimate care positively impacts their health and wellbeing. However, intimate care is still not one of the most frequent daily routines for many women.

Lichen planus - a clinical guide

Lichen planus (LP) is a chronic lichenoid inflammatory disorder of the skin, mucosa and of the appendages. LP is classically characterized by the presence of a rich infiltration of inflammatory T cells, which migrate in the upper part of the dermis, arranged in a band-like pattern. Different sub types of the disease have been so far described. Albeit LP is clinically well defined, the disease still represents a therapeutic enigma. Especially with regard to mucosal or scalp affecting LP types, which often present a recalcitrant and treatment unresponsive course, efficacious therapeutic options are still lacking. Thus, LP represents a disease with a high psychosocial burden. Yet, development in the deciphering of LP pathogenesis reveals possible new druggable targets, thus paving the way for future therapeutic options. In this clinical guide, we summarize the current clinical knowledge and therapeutic standards and discuss the future perspective for the management of LP.

Vulvar cancer in a patient with long-lasting premalignant lesions in the genital area: easily overlooked and difficult to diagnose - a case report and literature review

Vulvar intraepithelial lesions are a heterogenic group of diseases, which can be easily misdiagnosed. The case of a 61-year-old woman with a history of genital intraepithelial lesions and infection with HPV is presented. Her main complaint was vulvar pruritus. Vulvoscopy revealed the presence of two skin lesions: the first one had the morphology of lichen sclerosus, and the second of a Bowenoid lesion. The biopsy of the first lesion revealed vulvar intraepithelial neoplasia, whereas cells of squamous vulvar cancer were identified in the second lesion. After staging, the patient was advised to undergo hemivulvectomy and lymphadenectomy. The coexistence of morphologically diverse vulvar skin lesions may cause difficulties with diagnosis and the selection of an adequate treatment. Long-term follow-up and regular examination are essential for diagnosis of vulvar malignancies in the early stage.

Anogenital High-Grade Squamous Intraepithelial Lesion Comorbid With Vulvar Lichen Sclerosus and Lichen Planus

OBJECTIVE

The aim of the study was to describe the clinicopathologic features of vulvovaginal or anal high-grade squamous intraepithelial lesion (HSIL) comorbid with lichen sclerosus and/or lichen planus (LS/LP).

METHODS

The local pathology database identified 37 consecutive cases from 2007 to 2019 of vulvar, vaginal, or anal HSIL among women who had a histopathologic diagnosis of vulvar LS/LP. Cases had p16 and p53 immunoperoxidase stains. Clinical data included age, relative location of HSIL and LS/LP, immune-modifying conditions, tobacco use, treatment type, and follow-up. Histopathologic data included HSIL morphology categorized as warty-basaloid or keratinizing, p16 and p53 patterns within HSIL, and features of LS/LP.

RESULTS

The mean age was 69 years with a median follow-up up 42 months. Lichen sclerosus, alone or in combination with LP, was the comorbid dermatosis in 89%. Lichen sclerosus/lichen planus was overlapping or adjacent to HSIL in two-thirds of cases and located separately in the remainder. Rates of tobacco use and immunologic dysfunction were each 40%. In cases of co-located LS and HSIL, sclerosis was absent under the neoplasia in 57%. Twenty-four percent of HSIL cases showed keratinizing morphology; block-positive p16 and suprabasilar-dominant p53 helped distinguish HSIL from human papillomavirus-independent neoplasia.

CONCLUSIONS

Histopathologic identification of comorbid HSIL and LS/LP may be challenging because of keratinizing morphology and loss of diagnostic features of LS. Clinicopathologic correlation and use of p16 and p53 are essential to achieve an accurate diagnosis and enact disease-specific management plans.

Clinicopathologic Diagnostic Criteria for Vulvar Lichen Planus

OBJECTIVE

The aim of the study was to describe the clinical and histopathologic features required for a clinicopathologic diagnosis of vulvar lichen planus (LP), which is divided into 3 types: erosive, classic, and hypertrophic.

MATERIALS AND METHODS

The International Society of the Study of Vulvovaginal Diseases tasked the Difficult Pathologic Diagnoses committee with development of a consensus document for the clinicopathologic diagnosis of vulvar LP, lichen sclerosus, and differentiated vulvar intraepithelial neoplasia. The LP subgroup reviewed the literature and formulated diagnostic criteria, then approved by the International Society of the Study of Vulvovaginal Diseases membership.

RESULTS

The clinicopathologic diagnosis of erosive LP incorporates 5 criteria: (a) a well-demarcated, glazed red macule or patch at labia minora, vestibule, and/or vagina, (b) disease affects hairless skin, mucocutaneous junction, and/or nonkeratinized squamous epithelium, (c) evidence of basal layer damage, categorized as degenerative or regenerative, (d) a closely applied band-like lymphocytic infiltrate, and (e) absent subepithelial sclerosis. The clinicopathologic diagnoses of classic and hypertrophic LP each require a characteristic clinical appearance accompanied by hyperkeratosis, hypergranulosis, acanthosis, basal layer degeneration, a closely applied lymphocytic infiltrate, and absent dermal sclerosis, with hypertrophic LP showing marked epithelial abnormality compared with classic LP.

CONCLUSIONS

Clinicopathological correlation yields the most reliable diagnosis of vulvar LP. Disease appearance overlaps with other physiologic, dermatologic, infectious, and neoplastic entities; a low threshold for biopsy at all morphologically distinct areas is recommended. Use of the histopathologic criteria described in this document may reduce the nondiagnostic biopsy rate for clinically diagnosed LP.

Internet-based treatment for vulvodynia (EMBLA) - Study protocol for a randomised controlled study

BACKGROUND

Vulvodynia is defined as vulvar pain for at least 3 months without a clear cause. To the best of our knowledge, there are no trials investigating the effects of internet treatment using CBT (Cognitive behavioural therapy) treatment with Acceptance and Commitment Therapy (ACT) components for women with vulvodynia. The aim of this study is to examine the effects of such a guided internet-based intervention on provoked vulvar pain during the waiting period before clinical treatment.

METHODS

We will randomise 52 patients to either guided internet-based intervention with CBT with (ACT) components or no intervention during the waiting period for treatment as usual. Online assessments are conducted at baseline, posttreatment, and at follow-up after 9 months. The primary outcome measure is provoked vulvar pain. Secondary outcomes are depression, anxiety, sexual function, and quality of life. Linear-mixed effect models will be used to assess the effect of the internet-based intervention on vulvar pain, pain acceptance, depression, anxiety, sexual function, and quality of life over time, by applying the intention-to-treat approach. Continuous data will be analysed with general linear models using intention-to-treat and also per protocol approaches to assess the effects of the intervention at different time points. Ordinal and binary data will be analysed with Mann Whitney's test, Fischer's exact test and multivariate logistic regression, respectively.

DISCUSSION

As a randomised controlled trial with short- and long-term follow-up points, the EMBLA study intends to provide a novel and better understanding regarding the treatment of vulvodynia and the role of internet-based treatment as a complement to standard care for women suffering from vulvodynia. The effects of vulvodynia on pain, sexual function, quality of life, depression, and anxiety are investigated. The study's results are expected to be of value in the planning of clinical care in the medical area. High dropout rates and technical difficulties associated with using the platform are common in similar studies.

TRIAL REGISTRATION NUMBER

NCT02809612.

[Paediatric vulval clinic]

In 2008 a vulval clinic was established at the University Clinic of Schleswig Holstein, Campus Luebeck, Department of Dermatology. A total of 1227 patients were referred to the clinic between 2008 and October 2020, including 91 children (age range 1-13 years) and 17 adolescents (age range 14-17 years). The most common paediatric vulval conditions encountered were lichen sclerosus (33%), vulvitis (23%) and vulval psoriasis (7%). Quality of life was measured in 81 children using the paediatric version of the Dermatology Life Quality Index (DLQI). Of a maximum 30 points, the mean score was 7.2, confirming the association between vulval diseases and impaired quality of life in children and adolescents.

Glucocorticoid Receptor Beta and Its Prognostic Value on Treatment Response in Chronic Vulvar Dermatitis

BACKGROUND

Chronic vulvar dermatitis (CVD) is the most prevalent disease in gynecologic dermatology. The treatment mainly depends on topical glucocorticoids (TGC) but is challenged by insufficient treatment response. On a histological level, the upregulation of the glucocorticoid receptor β (GRβ), an inhibitor of the active glucocorticoid receptor α (GRα), is discussed as mechanism of glucocorticoid insensitivity.

OBJECTIVES

To analyze whether the expression of GRβ protein at baseline in keratinocytes may predict responsiveness to TGC in patients with CVD.

METHODS

In this retrospective cohort study, clinical and biological data of 25 women with a histological diagnosis of chronic vulvar eczema were analyzed. Randomization was done according to the responsiveness to TGC treatment (responsive vs. nonresponsive). Clinical data and the expression of GRβ in the immunohistochemical stained biopsies were examined.

RESULTS

Fifty-two percent of women with CVD were nonresponsive to TGC. GRβ was abundantly expressed in the cytoplasma of keratinocytes of the vulvar epithelium, but no difference in the level of expression was found among GC responsive and nonresponsive patients in the semiquantitative (p = 0.376) and quantitative analysis (p = 0.894).

CONCLUSION

GRβ is highly expressed in keratinocytes of the vulvar epidermis affected by CVD, but GRβ expression was not increased in patients nonresponsive to TGC compared to responsive patients. Thus, the failure mechanism in nonresponders still remains to be elucidated.

Microablative fractional radiofrequency as a therapeutic option for vulvar lichen sclerosus: a pilot study

OBJECTIVES

To assess the clinical response to and the histomorphometric effects of microablative fractional radiofrequency (MFR) in women with symptomatic vulvar lichen sclerosus (VLS).

METHODS

This was a pilot study on the use of MFR for the treatment of VLS. Upon recruitment and at each treatment session, all participants were examined and each of their symptoms were rated on a visual analog scale. After the procedure, the participants completed a satisfaction questionnaire. We compared the morphometric findings of vulvar biopsies performed at enrollment and after the last treatment session. The participants were divided into three groups according to previous treatment with corticosteroids: G1, no previous treatment; G2, treated for up to 5 years; and G3, treated for >5 years.

RESULTS

This study included 26 women. After two to three sessions, most participants in all groups became either "asymptomatic" or "much better" than before treatment and were "very satisfied" or "satisfied" with the intervention. Pruritus and burning sensation were the most frequently reported symptoms. Nearly 40% of the participants in all groups reported complete remission of symptoms. The improvement was rated as moderate or higher by 80%, 76%, and 66% of the women in groups 1, 2, and 3, respectively. The improvement of symptoms persisted for 11 months (range, 7-16 months), on average, after the treatment. Type III collagen concentration significantly increased and was associated with important symptom improvement. Tissue trophism and vascularization also increased but did not reach statistical significance, probably because of the small number of cases.

CONCLUSIONS

MFR may be an effective and safe treatment for symptomatic VLS.

Erosive Vulvar Lichen Planus and Risk of Vulvar Neoplasia

OBJECTIVE

The aim of the study was to assess the risk of vulvar cancer and precursors in a cohort of women with vulvar lichen planus (LP) and the clinical and therapeutic features of these patients.

MATERIALS AND METHODS

A retrospective cohort study, including all the women with the diagnosis of vulvar LP, followed in one institution during a period of 11 years, was performed. Demographic and clinical data, as well as treatment, follow-up, and histology results, were evaluated.

RESULTS

A total of 127 women were diagnosed with vulvar LP. The mean follow-up time was 3.9 ± 0.5 years (range = 1-11 years). Ultrapotent topical corticosteroids were first-line treatment in 91.8% (n = 112), with 32 cases (25.2%) needing an alternative treatment. Overall, 30 biopsies were performed in 19 women (15%). Vulvar high-grade squamous intraepithelial lesion was diagnosed in 3 women (2.4%), 2 (1.6%) of whom were later diagnosed with vulvar squamous cell carcinoma. No cases of differentiated vulvar intraepithelial neoplasia were observed.

CONCLUSIONS

Premalignant/malignant transformation in women with vulvar LP under surveillance and compliant with treatment is low. A close follow-up seems to be crucial to prevent future malignancy. Biopsies should be performed whenever a suspicious lesion seems during follow-up.

Diagnostic Criteria for Differentiated Vulvar Intraepithelial Neoplasia and Vulvar Aberrant Maturation

OBJECTIVE

The aim of the study was to describe the features required for diagnosis of differentiated vulvar intraepithelial neoplasia (dVIN) and vulvar aberrant maturation (VAM).

MATERIALS AND METHODS

The International Society of the Study of Vulvovaginal Diseases tasked the difficult pathologic diagnoses committee to develop consensus recommendations for clinicopathologic diagnosis of vulvar lichen planus, lichen sclerosus, and dVIN. The dVIN subgroup reviewed the literature and formulated diagnostic criteria that were reviewed by the committee and then approved by the International Society of the Study of Vulvovaginal Diseases membership.

RESULTS

Differentiated vulvar intraepithelial neoplasia is the immediate precursor of human papillomavirus (HPV)-independent vulvar squamous cell carcinoma and shows a spectrum of clinical and microscopic appearances, some overlapping with HPV-related neoplasia. The histopathologic definition of dVIN is basal atypia combined with negative or nonblock-positive p16 and basal overexpressed, aberrant negative, or wild-type p53. The most common pattern of dVIN is keratinizing with acanthosis, aberrant rete ridge pattern, and premature maturation. The morphologic spectrum of keratinizing dVIN includes hypertrophic, atrophic, acantholytic, and subtle forms. A few dVIN cases are nonkeratinizing, with basaloid cells replacing more than 60% of epithelium. Vulvar aberrant maturation is an umbrella term for lesions with aberrant maturation that arise out of lichenoid dermatitis and lack the basal atypia required for dVIN.

CONCLUSIONS

Evaluation of women at risk for dVIN and VAM requires a collaborative approach by clinicians and pathologists experienced in vulvar disorders. Close surveillance of women with lichen sclerosus and use of these recommendations may assist in prevention of HPV-independent squamous cell carcinoma through detection and treatment of dVIN and VAM.

Topographic Differential Diagnosis of Chronic Plaque Psoriasis: Challenges and Tricks

BACKGROUND

Psoriasis is an inflammatory skin disease presenting with erythematous and desquamative plaques with sharply demarcated margins, usually localized on extensor surface areas.

OBJECTIVE

To describe the common differential diagnosis of plaque psoriasis classified according to its topography in the scalp, trunk, extremities, folds (i.e., inverse), genital, palmoplantar, nail, and erythrodermic psoriasis.

METHODS

A narrative review based on an electronic database was performed including reviews and original articles published until 1 September 2020, assessing the clinical presentations and differential diagnosis for psoriasis.

RESULTS

Several differential diagnoses could be considered with other inflammatory, infectious, and/or neoplastic disorders. Topographical differential diagnosis may include seborrheic dermatitis, tinea capitis, lichen planopilaris in the scalp; lupus erythematosus, dermatomyositis, cutaneous T-cell lymphomas, atopic dermatitis, syphilis, tinea corporis, pityriasis rubra pilaris in the trunk and arms; infectious intertrigo in the inguinal and intergluteal folds and eczema and palmoplantar keratoderma in the palms and soles.

CONCLUSIONS

Diagnosis of psoriasis is usually straightforward but may at times be difficult and challenging. Skin cultures for dermatophytes and/or skin biopsy for histological examination could be required for diagnostic confirmation of plaque psoriasis.

Identification and management of vulval problems of the postmenopausal woman - Tips and tricks

Vulval irritation and discomfort can be a common presentation to both primary and secondary care. These symptoms can become increasingly prevalent due to physiological changes, which occur to the female genitalia following menopausal transition or due to inflammatory conditions. The correct diagnosis and management can have a huge impact on the patients' quality of life. However, due to the nature of the symptoms, there can be delayed presentation to healthcare professionals. This article gives an overview of the most common benign vulval conditions in the post-menopausal woman, their clinical features and the diagnosis and initial management.

Characterization of female intimate hygiene practices and vulvar health: A randomized double-blind controlled trial

BACKGROUND

Inappropriate feminine hygiene practices are related to vulvar unpleasant symptoms (such as skin changes, lesions, burning, pruritus, fissures, and dyspareunia).

AIMS

We assessed the daily use effects of intimate cleansers on vulvar skin by comparing two specific products for intimate care: Saugella Hydraserum (SIS), based on natural extracts, and a standard product based on lactic acid, such as Lactacyd Feminine Hygiene (LTC). Forty healthy women were enrolled in this double-blind controlled study.

METHODS

After randomization, the cleansers were used twice daily for 30 days. The hydration level was determined using the Corneometer® CM 825, the pH using the Skin-pH-Meter PH 905® and the sebum level using the Sebumeter SM815® . Measurements were performed at baseline and on day 30 on the labia majora and labia minora.

RESULTS

Both cleansers showed a reduction in the hydration level, but this was much less evident in the SIS group (-6.3% SIS vs -23,7% LTC). The pH values of the SIS group were lower than those of the LTC group, especially on the labia minora (5.27 ± 0.08 and 5.6 ± 0.1, respectively, P = .025). The sebum increased in both groups, but in the LTC group, it was higher on the labia majora (+96.2% vs +46.8%, respectively, P = .003), while on the labia minora, it was higher in the SIS group (+24.7% vs +17.1%, respectively P = NS).

CONCLUSIONS

Both cleansers tested showed high performance for safety and tolerability on vulvar skin, but SIS showed better efficacy than LTC on some parameters.

Therapeutic Effects of Focused Ultrasound on Expression of Notch1, C-Fos and Transforming Growth Factor-β3 in Vulvar Skin of SD Rats with Vulvar Lichen Simplex Chronicus

The purpose of this study was to investigate the therapeutic effects of focused ultrasound on the expression of notch1, c-fos and transforming growth factor-β3 (TGF-β3) in genital skin of SD rats with vulvar lichen simplex chronicus (LSC). Fifty-six female SD rats with LSC were randomly divided into therapy and sham groups. The therapy group was exposed to focused ultrasound. The sham group received the same therapy with an instrument that had no power output. Four wk after a singly focused ultrasound therapy, histologic analyses revealed that recovered SD rats accounted for 75% of SD rats in the therapy group and 10.7% in the sham group. Total collagen fiber density in the superficial layer of dermis in the therapy group was significantly lower than that in the sham group. Notch1 and c-fos protein expression in the therapy group was significantly lower than that in the sham group, with the opposite effect present for TGF-β3. Focused ultrasound therapy may inhibit superficial collagen fibrosis in the dermis by affecting expression of notch1, c-fos and TGF-β3 in vulvar skin tissue and consequently reduce the recurrence rate of LSC.

Missed opportunities: misconceptions and lack of knowledge about vulval skin care in women attending a sexual health clinic

Vulval skin care is an important part of women's health, and this evaluation aimed to explore vulval care among women attending our sexual health clinic. A questionnaire was completed by 135 women over a five-week period. Forty-three women (32%) washed their vulva two to three times a day, with 93 (69%) using a detergent-containing product. Thirty-eight women (28%) used sanitary products when not menstruating. Ninety-five women (70%) reported at least one previous vulvo-vaginal condition. One hundred and two women (76%) reported being confident in vulval care; however, 60 women (44%) wished to receive more information. The mismatch between women's confidence and knowledge may reflect mixed sources of education used by women. We recommend that sexual health clinics review the information they provide to patients on vulval care.

Forming diagnostic criteria for vulvar lichen planus

BACKGROUND/OBJECTIVES

Vulvar lichen planus is a debilitating skin condition usually complicated by delayed diagnosis due to its highly variable clinical appearance and inconsistent histopathological characteristics. This study aims to devise a clinical diagnostic tool for the disease and to correlate this with histopathology findings.

METHODS

The retrospective single-centre chart review was conducted for patients presenting between January 2010 and December 2019. Clinical features were compared between 243 women with clinically suspected vulvar lichen planus with available histopathology, 50 patients with biopsy-proven vulvar lichen sclerosus and 50 patients with culture-proven chronic vulvovaginal candidiasis. Features which significantly differentiated between conditions were further studied using multivariate nonlinear regression analyses to formulate a score-based diagnostic criteria. Criteria was then applied to the remaining patients with inconclusive biopsies (classified as 'normal', 'non-specific' or 'suggestive or lichenoid') to determine sensitivity and specificity.

RESULTS

The clinical features that significantly differentiated the conditions were the presence of erosions (P < 0.001), glazed erythema (P < 0.001), oral involvement (P < 0.001), pain/burning sensation (P < 0.001) and hyperkeratotic border (P < 0.001). A score ≥2 correlated with a histopathological diagnosis of vulvar lichen planus with a sensitivity of 100%. The specificity was 92% and 88% when compared against vulvar lichen sclerosus and chronic vulvovaginal candidiasis, respectively. Sensitivity was 97%, 97% and 93% in suggestive, nonspecific and normal histopathological subgroups, respectively.

CONCLUSIONS AND RELEVANCE

The proposed criteria may aid clinicians in diagnosing patients if histopathology is inconclusive. Nonspecific and suggestive findings on biopsy for patients with ≥2 features on diagnostic criteria are comparable to a conclusive biopsy.

Vulvar pruritus-Causes, Diagnosis and Therapeutic Approach

BACKGROUND

In Germany, 17-23% of the population suffers from chronic itching of the skin; in 5-10% of cases, the female genitalia are affected, specifically, the vulva. Vulvar pruritus is thus a common symptom that often markedly impairs the affected women's quality of life.

METHODS

This review is based on pertinent publications that were retrieved by a selective search in MEDLINE/PubMed for articles on the pathogenesis, diagnosis, and treatment of vul- var pruritus. The search terms were (in German and English) "vulvärer Juckreiz," "pruritus vulvae," and "genital itch," alone and in combination with "Behandlung," "Therapie," or "treat- ment."

RESULTS

The most common cause of vulvar pruritus is vulvo- vaginal candidiasis followed by chronic dermatoses, such as lichen sclerosus and vulvar eczema. Especially in refractory cases, an invasive or preinvasive lesion such as squamous epithelial dysplasia (VIN, vulvar intraepithelial neoplasia) should be borne in mind in the differential diagnosis. Rarer causes include infection, atrophy, and vulvodynia. The essen- tial elements of treatment are topical/oral antimycotic drugs and high-potency glucocorticoids, along with consistently ap- plied, basic moisturizing care and the avoidance of potential triggering factors.

CONCLUSION

As vulvar pruritus has multiple causes, standard- ization of its diagnostic evaluation and treatment would be l efficacy and to meet the diverse needs of women who suffer from this condition.

Concordance rate of vulvoscopic findings in detecting early vulvar neoplasia

PURPOSE

Colposcopy-guided punch biopsy is a cornerstone method for diagnosing vulvar diseases. The aim of this study was to evaluate the concordance rate of clinical findings in vulvar diseases during examinations, in comparison with colposcopy-directed punch biopsy. We also developed a new classification to simplify the categorization of vulvoscopic findings.

METHODS

The concordance rate of the clinical findings was compared with the final histology results from punch biopsies. The data were collected between January 2014 and May 2017 at the Erlangen University Hospital.

RESULTS

A total of 482 colposcopy-directed punch biopsies of the vulva were obtained in 420 women. The overall concordance rate of the clinical findings in comparison with the histological vulvar punch-biopsy findings was 53.9% for all entities - benign lesions, lichen, low- and high-grade squamous intraepithelial lesions (LSIL/HSILs), and vulvar carcinoma. The concordance rate for detecting LSILs was 64.3% (45/70). The concordance rate for detecting HSILs was 62.3% and for Vulvar carcinoma 65.2%.

CONCLUSIONS

Punch biopsy of suspicious lesions continues to be a cornerstone in diagnosing HSILs and carcinoma of the vulva. Careful work-up of the vulva is recommended when patients have symptoms such as pruritus or pain. The new classification is more specific for diagnosing lesions in the vulva.

[Focused ultrasound therapy for reducing recurrence of vulvar lichen simplex chronicus in rats: efficacy and mechanism]

OBJECTIVE

To explore the changes of collagen fibrosis in the vulva skin of SD rats with lichen simplex chronicus (LSC) after focused ultrasound therapy and explore the mechanism by which focused ultrasound reduces the recurrence of vulvar LSC.

METHODS

Fifty female SD rat models of vulvar LSC were established and randomly divided into the treatment group and the control group (n=25) for treatment with focused ultrasound and sham treatment, respectively. Before and after the treatment, vulvar skin tissues were sampled to observe the pathological changes with HE staining and assess the density of collagen fibers using Masson staining. The ultrastructure of the collagen fibers in the superficial dermis was observed using transmission electron microscopy. The expressions of notch1 and c-fos in the vulvar tissue were detected by immunohistochemistry and Western blotting.

RESULTS

After 4 weeks of focused ultrasound therapy, 16% (4/25) of the rats in the treatment group showed lesion progression to LSIL, 4% (1/25) still had LSC, and 80% (20/25) showed normal vulvar skin. In the control group, progression to LSIL occurred in 19 (76%) rats, 3 (12%) rats still showed LSC, and only 3 (12%) had normal vulvar skin. The difference in the cure rate differed significantly between the two groups (P < 0.05). The density of collagen fibers in the superficial dermis and the expressions of notch1 and c-fos in the vulvar skin were significantly lower in the treatment group than in the control group (P < 0.05).

CONCLUSIONS

Focused ultrasound therapy can inhibit superficial collagen fibrosis of the dermis by lowering the expressions of notch1 and c-fos in the vulvar skin to reduce the recurrence of vulvar LSC in rats.
