Systematic review and meta-analysis of randomized controlled trials on topical interventions for genital lichen sclerosus

Clinical outcomes with utilization of high-potency topical steroids in patients with lichen sclerosus-associated vulvar cancer

OBJECTIVES

To evaluate the impact of high-potency topical steroid use on risk of recurrence of lichen sclerosus-associated vulvar cancer.

METHODS

This is a retrospective cohort study evaluating patients with lichen sclerosus (LS)- associated vulvar squamous cell cancer (VSCC). Demographic and clinical outcome data were compared between two comparison groups: patients who received steroids, mainly clobetasol, and patients who did not receive steroids following treatment of LS-related vulvar cancer. Categorical variables were compared using Fisher's exact test or chi-square test. Continuous variables were compared using a two-sided student's t-test. Time to recurrence (TTR) and overall survival (OS) were analyzed using Kaplan-Meier survival plot and compared using Mantel-Cox log rank test. Cox proportional hazard regression models were conducted to generate hazard ratios for both TTR and OS. A p value of <0.05 was considered statistically significant.

RESULTS

A total of 49 patients were included, with 36 patients receiving steroid treatment and 13 patients in the expectant management group. The median age of diagnosis was 68. The average BMI was 31.7 +/- 7.0. The median length of follow up was 41 months. The majority of patients were diagnosed with stage I VSCC. There was no difference in demographics or oncologic management of vulvar cancer between the two cohorts. Overall recurrence was decreased among patients who received steroid treatment when compared to patients who did not, 12 patients (33.3%) versus 9 patients (69.2%) respectively (p = 0.048).

CONCLUSIONS

High-potency topical steroid use following treatment of lichen sclerosus-associated vulvar squamous cell carcinoma is associated with decreased risk of recurrence and prolonged median time to recurrence.

Assessment of the Cutaneous Hormone Landscapes and Microbiomes in Vulvar Lichen Sclerosus

Vulvar lichen sclerosus (VLS) is a progressive skin disease of unknown etiology. In this longitudinal case-control exploratory study, we evaluated the hormonal and microbial landscapes in 18 postmenopausal females (mean [SD] age: 64.4 [8.4] years) with VLS and controls. We reevaluated the patients with VLS after 10-14 weeks of daily topical class I steroid. We found that groin cutaneous estrone was lower in VLS than in controls (-22.33, 95% confidence interval [CI] = -36.96 to -7.70; P = .006); cutaneous progesterone was higher (5.73, 95% CI = 3.74-7.73; P < .0001). Forehead 11-deoxycortisol (-0.24, 95% CI = -0.42 to -0.06; P = .01) and testosterone (-7.22, 95% CI = -12.83 to -1.62; P = .02) were lower in disease. With treatment, cutaneous estrone (-7.88, 95% CI = -44.07 to 28.31; P = .62), progesterone (2.02, 95% CI = -2.08 to 6.11; P = .29), and 11-deoxycortisol (-0.13, 95% CI = -0.32 to 0.05; P = .15) normalized; testosterone remained suppressed (-7.41, 95% CI = -13.38 to -1.43; P = .02). 16S ribosomal RNA V1-V3 and ITS1 amplicon sequencing revealed bacterial and fungal microbiome alterations in disease. Findings suggest that cutaneous sex hormone and bacterial microbiome alterations may be associated with VLS in postmenopausal females.

Photodynamic therapy for male genital lichen sclerosus with urethral stricture-Case report

Male genital lichen sclerosus (MGLSc) typically impacts the external genitalia, resulting in balanitis, erectile pain, urination symptoms, and/or urinary retention. Urethral stricture develops in up to 20 % of these patients, which is usually found in the distal part of the urethra but can, in severe instances, impact the entire urethra and cause structural changes. Patients with skin lesions limited to the foreskin and partially extending to the glans can typically be cured by circumcision, but the recurrence rate of stricture is high when the glans or urethra is extensively involved. In the following case report, we describe a 45-year-old man with a history of MGLSc for 3 years and urethral stricture for 2 years, and these conditions remained untreated after circumcision. We emphasize that treatment with 5-aminolevulinic acid-induced photodynamic therapy (ALA-PDT) may further improve outcomes in such severe cases.

Penile Lichen Sclerosis: A Surgical Perspective of its Aetiology and Treatment

Penile lichen sclerosis is a longstanding inflammatory disease of the skin with a controversial aetiology. Penile lichen sclerosis (PLS) is a growing, inflammatory dermatitis of the anogenital region, which involves the meatus, prepuce, penile shaft, and glans penis. Although the accurate aetiology of PLS is contentious, multiple factors including genetics, autoimmunity, infections of human papillomavirus, hepatitis C, Epstein-Barr virus, risk factors (hormonal and trauma), etc., can be considered to be a part of the etiopathogenesis of PLS. The initial clinical presentations of penile lichen sclerosis are white plaques, atrophied skin, erythema, erosions, and sclerosis in the anogenital region. When the disease advances, the following can occur, including meatal constraints, telangiectasia, petechiae, soreness, papular lesions, tightness of the foreskin, difficulties in passing urine, itching, tenderness on erections, pain, cracking, bleeding, redness, rashes, tightness at frenulum, and dysuria. This disease has a dangerous course of action and if untreated it may be linked with severe urologic and sexual morbidities. PLS is usually treated with medical and surgical interventions like topical or intralesional steroids and circumcision. The role of circumcision is very critical in the course of action and prognosis of PLS, and its treatment is dependent on the stage of the disease. This review brings up the knowledge regarding epidemiology, etiopathology, clinical presentation, and management of PLS with an emphasis on the role of circumcision.

Efficacy of topical progesterone versus topical clobetasol propionate in patients with vulvar Lichen sclerosus - A double-blind randomized phase II pilot study

BACKGROUND

Lichen sclerosus (LS) is a chronic inflammatory skin disease that mostly affects the anogenital region of women and lowers patients' quality of life. Current standard treatment of LS is topical steroids.

OBJECTIVE

To evaluate the efficacy of topical progesterone 8% ointment and compare to standard therapy with topical clobetasol propionate 0.05% in premenopausal women presenting with previously untreated early onset LS.

STUDY DESIGN

Randomized, double-blind, 2-arm, single center superiority trial in premenopausal women with histologically confirmed vulvar LS who were randomized in a 1:1 ratio to receive clobetasol propionate 0.05% ointment or progesterone 8% ointment. The primary outcome was the clinical severity LS score after 12 weeks, which consists of six clinical features assessed by the physician. Secondary outcomes were the symptom severity LS score, which consists of three symptoms rated by the patient, the Short Form SF-12 physical and mental health scores, and adverse events. Response to medication was assessed by biopsy at the end of the treatment to evaluate inflammatory parameters.

RESULTS

Overall, 105 women were screened, 102 underwent vulvar biopsy and 37 received a histologically confirmed diagnosis of LS and were randomized: 17 to progesterone and 20 to clobetasol propionate. At 12 weeks, the mean clinical LS scores improved from 4.6 (SD 2.0) to 4.5 (SD 1.7) in the progesterone arm, and from 4.6 (SD 2.8) to 2.9 (SD 2.2) in the clobetasol propionate arm (difference in favor of clobetasol 1.61; 95% CI 0.44 to 2.77, p = 0.009), and the mean symptom severity LS scores improved from 4.5 (SD 3.8) to 3.1 (SD 3.0) in the progesterone arm, and from 4.7 (SD 2.8) to 1.9 (SD 1.8) in the clobetasol propionate arm (difference in favor of clobetasol 1.32; 95% CI -0.25 to 2.89, p = 0.095). LS was in complete remission in 6 out of 10 patients (60%) with available biopsy in the progesterone arm, and in 13 out of 16 patients (81.3%) in the clobetasol propionate arm (odds ratio in favor of clobetasol 0.35; 95% CI 0.06 to 2.06, p = 0.234). No drug-related serious adverse event occurred during the trial.

CONCLUSIONS

Topical progesterone 8% ointment is inferior to standard therapy with topical clobetasol propionate 0.05% in previously untreated premenopausal women with vulvar LS after 12 weeks treatment.

Does compliance to topical corticosteroid therapy reduce the risk of development of permanent vulvar structural abnormalities in pediatric vulvar lichen sclerosus? A retrospective cohort study

BACKGROUND

Vulvar lichen sclerosus (VLS) is a chronic inflammatory dermatosis of the genital skin, with up to 20% of cases in the pediatric age group. Limited data exist concerning the prognosis of pediatric VLS, particularly the likelihood of permanent architectural change and whether this can be prevented by compliance with topical corticosteroid treatment (TCS).

OBJECTIVE

To evaluate the extent to which compliance to TCS treatment influences the risk of developing vulvar structural abnormalities, including clitoral phimosis and diminutive or fused labia minora.

METHODS

A retrospective chart review of case records of pediatric-age females with VLS between January 31, 2004 and January 31, 2021.

RESULTS

One hundred eighteen cases of VLS were identified, with a mean age at diagnosis of 7.25 years and a mean follow-up period of 42.7 months. Thirty-four girls were "partially compliant," whereas 84 were "compliant." The risk ratio (RR) of developing any vulvar structural abnormality or clitoral phimosis was 5.76 (95% CI 2.96-11.3) and 21.2 (95%CI 5.23-85.9) times higher, respectively, in partially compliant compared with compliant subjects. The RR of a partially compliant female with pre-pubertal onset VLS having a vulvar structural abnormality persisting beyond menarche was increased 3.54-fold relative to compliant females (95% CI 1.75-7.17).

LIMITATIONS

The retrospective nature of our data, lack of a control group, wide variability in follow-up duration, and nonstandardized method of stratifying compliance.

CONCLUSION

Vulvar structural abnormalities are common in prepubertal onset VLS. Compliance to TCS appears to be critical in the prognosis of pediatric VLS although attitudes underpinning noncompliance to TCS treatment require further elucidation.

Assessing the compliance of systematic review articles published in leading dermatology journals with the PRISMA statement guidelines: A systematic review

Background

Reporting quality of systematic reviews and meta-analyses is of critical importance in dermatology because of their key role in informing health care decisions.

Objective

To assess the compliance of systematic reviews and meta-analyses in leading dermatology journals with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement guidelines.

Methods

This review was carried out in accordance with PRISMA guidelines. Included studies were reviews published across 6 years in the top 4 highest-impact-factor dermatology journals of 2017. Records and full texts were screened independently. Data analysis was conducted with univariate multivariable linear regression. The primary outcome was to assess the compliance of systematic reviews and meta-analyses in leading dermatology journals with the PRISMA statement.

Results

A total of 166 studies were included and mean PRISMA compliance across all articles was 73%. Compliance significantly improved over time (β = .016; P = <.001). The worst reported checklist item was item 5 (reporting on protocol existence), with a compliance of 15% of articles.

Conclusion

PRISMA compliance within leading dermatology journals could be improved; however, it is steadily improving.

Quality of life of women with untreated vulval lichen sclerosus assessed with vulval quality of life index (VQLI)

BACKGROUND/OBJECTIVE

The diagnosis of vulval lichen sclerosus (VLS) is often delayed, and little is known about quality of life (QoL) of women with it prior to receiving diagnosis and treatment. This study aimed to investigate the impact on QoL on patients with previously untreated VLS using the Vulval Quality of Life Index (VQLI).

METHODS

A prospective cross-sectional survey of patients attending a dermato-gynaecology practice in Sydney, Australia from March 2018 to November 2019. Patients with a new biopsy-proven diagnosis of VLS not previously commenced on topical corticosteroid treatment were invited to complete the VQLI.

RESULTS

A total of 68 participants with median age of 58 (interquartile range, IQR 48-67) years. Median symptom duration was 24 (IQR 11-60) months. Scarring was present in 53% of participants. The median total score was 13.5 (IQR 7.5-22.0), global score 1.0 (IQR 1.0-2.0). Twelve per cent had nil to minimal effect on QoL, 38% had a mild effect on QoL, 28% had a moderate effect on QoL, 22% had a severe effect on QoL, and none had a very severe effect on QoL. The highest-scoring domains were symptoms, followed by sexuality, anxiety and activities of daily living.

CONCLUSION

There was significant impairment in all QoL areas of women with untreated VLS. Most experienced moderate-to-severe impairment as a result of the disease and approximately half had already developed scarring at the time of diagnosis. The findings emphasise the importance of improved awareness, early diagnosis and early commencement of treatment in VLS.

An arm-based network meta-analysis on treatments for vulvar lichen sclerosus and a call for development of core outcome sets

OBJECTIVE

The purpose of the present systematic review is to evaluate the available medical treatments for vulvar lichen sclerosus, using an arm-based network meta-analysis protocol.

DATA SOURCES

We searched Medline (1966-2019), Scopus (2004-2019), Cochrane Central Register of Controlled Trials CENTRAL (1999-2019), Clinicaltrials.gov (2008-2019) databases, and Google Scholar (2004-2019) database along with the reference list of all included studies.

STUDY ELIGIBILITY CRITERIA

All observational, randomized, and single-arm studies that evaluated medical treatments for vulvar lichen sclerosus were considered eligible for inclusion in the present systematic review.

STUDY APPRAISAL

A network meta-analysis was carried out in R 3.4.3 using the pcnetmeta package, which uses a Bayesian hierarchical model (based in Markov chain Monte Carlo convergence simulation).

RESULTS

Sixteen studies were included in this present meta-analysis, which recruited 954 women with vulvar lichen sclerosus. Their quality was evaluated with the JADAD, Cochrane risk of bias, and risk of bias in nonrandomised studies of interventions-I tools. Clobetasol treatment ranked as the best treatment for disease remission after evaluating rank probabilities (40% chance of ranking first compared with tacrolimus [38%]). However, the density plot revealed partial overlapping with tacrolimus. The lowest probability of experiencing a relapse was observed with pimecrolimus (15% [2-48%]); however, the density plot revealed significant overlapping with mometasone furoate, testosterone, and clobetasol.

CONCLUSION

Robust evidence concerning the superiority of potent steroids at least over calcineurin inhibitors is still lacking in the field of vulvar lichen sclerosus. On the other hand, the gross heterogeneity in terms of selected population, duration of treatment, administered regimen, outcome reporting, and selection of outcome measures leaves several fields unanswered.

Off-Label Use of Topical Calcineurin Inhibitors in Dermatologic Disorders

Off-label prescribing is a common practice in dermatology, particularly when uncommon dermatologic diseases have limited or no approved treatment options. Topical calcineurin inhibitors are approved for the treatment of eczema, and their anti-inflammatory, immunomodulatory, and steroid-sparing effects make them an attractive therapeutic option for a wide variety of other dermatologic diseases. This review summarizes and qualifies the available evidence supporting the clinical effectiveness of tacrolimus ointment and pimecrolimus cream in non-eczema indications. There is high-quality evidence supporting the effectiveness of topical calcineurin inhibitors in multiple dermatological disorders including vitiligo; psoriasis of the face, folds, and genitals; seborrheic dermatitis; chronic hand dermatitis; contact dermatitis; oral lichen planus; lichen sclerosus; morphea; and cutaneous lupus erythematosus. Lower-quality evidence suggests they may be considered as an option in many other cutaneous disorders.

Balanitis xerotica obliterans: an update for clinicians

Lichen sclerosus (LS) is a severe, chronic, dermatosis characterised by inflammatory, sclerotic, pruritic lesions that causes significant morbidity in patients of all genders and ages. In boys, the lesions typically affect the foreskin and glans (termed balanitis xerotica obliterans (BXO)), leading to phimosis and potentially meatal stenosis. The incidence of the disease is not well reported but the average age of affected boys is 8 years (range 1-16). Diagnosis can often be made clinically, although histological study remains important to rule out important differential diagnoses. Complications include genital scarring, urinary and sexual dysfunction as well as the development of carcinomas in adult life. Circumcision has been regarded as definitive management of BXO in boys, but this may be supplemented with medical therapies such as topical steroids, immune modulators, intralesional triamcinolone and ozonated olive oil. Supportive measures including emollients, avoidance of irritants, surveillance of complications and recurrence as well as education and counselling remain important.Conclusion: BXO remains an important cause of phimosis in boys. The frequency of this condition appears unclear but seems likely to be less than 1% of males. Treatment generally involves circumcision, with some evidence that topical steroids or immunomodulators may decrease the incidence of recurrent meatal stenosis.What is Known:• Surgical circumcision is considered the definitive management of BXO• Many aspects of BXO are still in contention or require further study including the epidemiology and aetiology.What is New:• There is increasing awareness of non-surgical modalities that may be used in adjunct to surgery including topical corticosteroids, immune modulators, intralesional triamcinolone and ozonated olive oil• Awareness of meatal stenosis-related BXO has led to the development of surgical techniques such as preputioplasty as well as buccal mucosal inlay grafts.

Raman spectroscopy and multivariate analysis for the non invasive diagnosis of clinically inconclusive vulval lichen sclerosus

Vulval lichen sclerosus (LS) is a common inflammatory condition associated with an increased risk of developing vulval carcinoma. Diagnosis is usually clinical although biopsy is necessary if the diagnosis is uncertain or if there is a failure to respond to adequate initial treatment. Raman spectroscopy has the potential to be applied in vivo for near real time objective non-invasive optical diagnosis, avoiding the need for invasive tissue biopsies. The aim of this study was to evaluate the diagnostic performance of Raman spectroscopy for differentiating LS from other vulval conditions in fresh vulval biopsies. Biopsies were analysed from 27 women with suspected LS in whom the attending gynaecologist could not establish the diagnosis on clinical presentation alone. Spectral variance was explored using principal component analysis and in conjunction with the histological diagnoses was used to develop and test a multivariate linear discriminant classification model. This model was validated with leave one sample out cross validation and the diagnostic performance of the technique assessed in comparison with the pathology gold standard. After cross validation the technique was able to correctly differentiate LS from other inflammatory vulval conditions with a sensitivity of 91% and specificity of 80%. This study demonstrates Raman spectroscopy has potential as a technique for in vivo non-invasive diagnosis of vulval skin conditions. Applied in the clinical setting this technique may reduce the need for invasive tissue biopsy. Further in vivo study is needed to assess the ability of Raman spectroscopy to diagnose other vulval conditions before clinical application.

Diagnostic criteria, severity classification and guidelines of lichen sclerosus et atrophicus

We established diagnostic criteria and severity classification of lichen sclerosus et atrophicus, because there is no established diagnostic criteria or widely accepted severity classification of the disease. Also, there is no clinical guideline for lichen sclerosus et atrophicus in Japan, so we proposed its clinical guideline. The clinical guidelines were formulated by clinical questions and recommendations on the basis of evidence-based medicine according to the New Minds Clinical Practice Guideline Creation Manual (version 1.0). We aimed to make the guidelines easy to use and reliable including the newest evidence, and to present guidance for various clinical problems in treatment of lichen sclerosus et atrophicus.

Development of the Adult Vulvar Lichen Sclerosus Severity Scale-A Delphi Consensus Exercise for Item Generation

Through expert international consensus, 24 items are proposed for inclusion in a future validated adult vulvar lichen sclerosus severity scale.

Supplemental digital content is available in the text.

Objective

To generate a list of items through international expert consensus consisting of both symptoms and clinical signs for inclusion in an adult vulvar lichen sclerosus severity scale.

Methods

This study was carried out as a three-stage Delphi consensus exercise. After an extensive literature review, any items used to determine disease severity in previous clinical trials were compiled into a survey. The Delphi participants were recruited from the International Society for the Study of Vulvovaginal Disease most of whom were gynecologists and in practice for more than 20 years. Participants were asked to rate the importance of these items. Consensus was defined as 75% agreeing that an item was very important or essential toward determining disease severity. Participants were also asked to indicate preferred method of measurement for these items.

Results

Of approximately 400 members of the International Society for the Study of Vulvovaginal Disease, 66 participated in the study. Of the 14 symptoms presented, 7 reached consensus for inclusion. Of the 23 signs presented, 11 reached consensus for inclusion and 1 reached consensus for exclusion. Of the six architectural changes presented, all six reached consensus for inclusion. No consensus was reached regarding method of measurement for any of the symptoms and signs that reached consensus for inclusion.

Conclusion

International consensus was reached for a variety of items for use in an adult vulvar lichen sclerosus severity scale that will be further developed and tested. Ideally, this scale will be used in clinical practice and in research to allow for high-quality trials.

Anti-Inflammatory and Tissue Regenerative Effects of Topical Treatment with Ozonated Olive Oil/Vitamin E Acetate in Balanitis Xerotica Obliterans

Balanitis xerotica obliterans (BXO) is a chronic inflammatory skin disorder, considered the male genital variant of lichen sclerosus. Anti-inflammatory drugs are commonly used in BXO. We evaluated the effects of an innovative formulation of ozonated olive oil with vitamin E acetate (OZOILE®) on the inflammatory status and tissue remodeling in male children with BXO. The mRNA transcripts of proteins involved either in inflammation or in dynamics of tissue regeneration were analyzed by quantitative real-time PCR, in foreskins affected by BXO removed from patients untreated or treated with OZOILE® cream for 7 days before circumcision. We found a significant reduction in mRNA levels of IL-1β, TNF-α, INF-γ, transglutaminase 2 and NOS2 in foreskins treated with OZOILE® in comparison to untreated ones (p < 0.001). No significant differences were observed in NF-κB activation in the specimens obtained from treated and untreated patients. Hence, OZOILE® treatment up-regulated hypoxia-inducible factor (HIF)-1alpha, vascular endothelial growth factor (VEGF) and E-cadherin gene expression (p < 0.001). The treatment with OZOILE® showed effective results in children affected by BXO by reducing the inflammatory process and stimulating mechanisms for tissue regeneration of the foreskin. A randomized clinical trial on a large number of children affected by BXO might be useful to verify the efficacy of topical treatment with OZOILE®.

A Pediatric Case of Disseminated Lichen Sclerosus – a Case Report

Lichen sclerosus (LS) is an uncommon chronic inflammatory skin disorder with a predilection for the anogenital area, characterized by porcelain white papules, plaques and atrophic patches. We report a prepubertal, 12-year-old girl who presented with chronic, disseminated pearly, flat-topped papules, plaques and atrophic patches located on the trunk, limbs and in the anogenital area, consistent with LS based on clinical and histologic findings. Potent and ultrapotent topical corticosteroids should be considered as first-line treatment. The ultraviolet A1 (UVA1) and calcipotriol for extragenital lesions, as well as calcineurin inhibitors for anogenital lesions, are other treatment options for pediatric LS.

Photodynamic therapy in the treatment of vulvar lichen sclerosus

BACKGROUND

Vulvar lichen sclerosus is a chronic and incurable disease that causes various unpleasant symptoms and serious consequences.

OBJECTIVE

The purpose of the study was to assess the effectiveness of photodynamic therapy in the treatment of vulvar lichen sclerosus.

METHODS

Participants in the study included 102 female patients aged 19-85 suffer from vulvar lichen sclerosus. The patients underwent photodynamic therapy (PDT). In the course of PDT the 5% 5- aminolevulinic acid was used in gel form. The affected areas were irradiated with a halogenic lamp PhotoDyn 501 (590-760nm) during a 10-min radiation treatment. The treatment was repeated weekly for 10 weeks.

RESULT

PDT has brought about a good therapeutic effect (complete or partial clinical remission), with 87.25% improvement rate in patients suffering from lichen sclerosus. The greatest vulvoscopic response was observed in the reduction of subepithelial ecchymoses and teleangiectasia (78.95%), and the reduction of erosions and fissures (70.97%). A partial remission of lichenification with hyperkeratosis was observed in 51.61% of cases. The least response was observed in the atrophic lesions reduction (improvement in 37.36% of cases).

CONCLUSION

Our patients suffering from vulvar lichen sclerosus demonstrated positive responses to photodynamic therapy and the treatment was well tolerated. Photodynamic therapy used to treat lichen sclerosus yields excellent cosmetic results.

Bleeding after circumcision is more likely in children with lichen sclerosus (balanitis xerotica obliterans)

INTRODUCTION

Over 27,000 circumcisions were performed in England in 2012-13. The complication rate is generally perceived to be low, although published figures vary widely. Balanitis xerotica obliterans, more correctly termed Lichen Sclerosus et atrophicus (LS), is one of the commonest indications for medical circumcision. To test the hypothesis that children undergoing circumcision for LS have a higher rate of postoperative bleeding than those undergoing the procedure for other reasons, we retrospectively reviewed records for patients undergoing circumcision.

METHODS

The disease and procedure coding system was used to identify patients who underwent circumcision (ICD10 code N303) between 2000-2010. Cases with a diagnosis unrelated to circumcision and children circumcised during hypospadias repair were excluded. Bleeding which required return to theatre for surgical arrest was considered significant. Cases were identified by review of medical records if there was: a second procedure during the same admission, or readmission coded for circumcision within 2 weeks. Only cases with histologically confirmed LS were included in the LS cohort. GraphPad online calculator was used for statistical analysis (two tailed Fisher's exact test.

RESULTS

2385 boys with a median age of 4 years (range 0-16) were included in the study. Indication for circumcision included religious (1305, 54.7%), phimosis or redundant prepuce (512, 21.5%), suspected LS (366, 15.4%) and balanoposthitis (202, 8.5%). LS was histologically confirmed in 262 (10.9%) boys. Fourteen (0.6%) patients returned to theatre for surgical arrest of bleeding following circumcision; 6 had LS and 8 did not (Table 1). The bleeding rate was higher in those with LS (2.3%) than in those without (0.3%), P = 0.0003 with a relative risk of 6.08.

CONCLUSION

Post-operative complications are distressing, especially if further surgery is required. Published figures for complications following circumcision vary widely making counseling regarding risk difficult. Since LS includes an inflammatory element and circumcision in widespread LS can be challenging, the observation of more post-operative bleeding in patients with histologically confirmed LS during a previous audit prompted the hypothesis that this may be a significant finding. Thus we reviewed all patients requiring return to theatre within 2 weeks of circumcision, finding that whilst the overall bleeding rate was low, circumcision for LS significantly increased the risk. Although factors such as the severity of LS and surgical technique were not assessed, this is still a notable finding which should be reflected during pre-operative counseling.

Vulvar Lichen Sclerosus et Atrophicus

Vulvar lichen sclerosus (VLS) is a chronic inflammatory dermatosis characterized by ivory-white plaques or patches with glistening surface commonly affecting the vulva and anus. Common symptoms are irritation, soreness, dyspareunia, dysuria, and urinary or fecal incontinence. Anogenital lichen sclerosus (LS) is characterized by porcelain-white atrophic plaques, which may become confluent extending around the vulval and perianal skin in a figure of eight configuration. Thinning and shrinkage of the genital area make coitus, urination, and defecation painful. LS is not uncommon in India and present as an itchy vulvar dermatosis which a gynecologist may mistake for candidal vulvovaginitis. There is often a delay in diagnosis of VLS due to its asymptomatic nature and lack of awareness in patients as well as physicians. Embarrassment of patients due to private nature of the disease and failure to examine the genital skin properly are the other reasons for delay in diagnosis. There is no curative treatment for LS. Various medications available only relieve the symptoms. Chronic nature of the disease affects the quality of life. Proper and regular follow-up is required as there are chances of the development of squamous cell carcinoma.

Photodynamic therapy with green light for the treatment of vulvar lichen sclerosus - Preliminary results

INTRODUCTION

The standard treatment for lichen sclerosus (LS) is symptomatic and is primarily based on the chronic use of corticosteroids, sometimes resulting in unsatisfactory effects. Therefore, other non-pharmacological methods are being sought, which are less aggravating for the patient. LS can be treated topically by using photodynamic therapy (PDT) based on 5-aminolevulinic acid (5-ALA). Unfortunately, therapy with the red light is often connected with severe local pain during the illumination. Green light can also be characterised by its ability to turn on photodynamic reactions in cells.

MATERIALS AND METHODS

The aim of this study was an evaluation into the efficacy and tolerance of 5-ALA-PDT with a green light (540nm±15nm) in 11 patients with chronic LS that were characterised by severe itching. The disease lasted from 1.5 to 4 years. All the patients were treated with three sessions of PDT.

RESULTS

Following treatment with PDT, a significant improvement of local status, as well as a reduction of the main symptom (pruritus), were observed. No patient complained of severe pain during the sessions that would have required an interruption of irradiation or local application of analgesics.

CONCLUSIONS

Our preliminary results of using green light in PDT for superficial skin non-oncological lesions are very promising but require further studies.

[Differential diagnosis and management of balanitis]

Balanitis is a descriptive diagnosis for a heterogeneous group of infectious or inflammatory dermatoses which have to be differentiated from malignant conditions. Balanitis is caused not only by Candida spp. and bacterial infections, including anaerobic bacteria: viral infections, parasites and other sexually transmitted infections (STI) also have to be considered. Lichen planus, psoriasis and contact dermatitis can characteristically lead to inflammatory conditions of the glans penis. In addition to a complete skin examination, a thorough patient history with respect to topically applied products and sexual behavior is essential. Infections must be treated and the glans penis should be kept dry. It is important to ensure a balanced genital hygiene in patients. As a last resort therapeutic circumcision can be considered for most forms of chronic balanitis.

Pediatric Lichen Sclerosus: A Review of the Epidemiology and Treatment Options

Lichen sclerosus (LS) is a rare, chronic, inflammatory disease of the skin that primarily affects postmenopausal women but may occur in men and children as well. Approximately 7% to 15% of cases are believed to occur in children. The epidemiologic data for LS have been limited and treatment options are not well studied, particularly in children. We reviewed new developments available in the current literature on the epidemiology and management of LS for children.

Lower Anogenital Tract Disease Therapy Outcomes, COMET, and CROWN: Call for Research Submissions

OBJECTIVES

There is a problem of inconsistent and inappropriate outcome selection for research studies. We can improve the relevance of research results for women and for their physicians and clinicians by encouraging researchers to critically evaluate outcome measures, and use valid, appropriate, standardized measures. To this purpose, and to facilitate synthesis of the evidence, outcomes reported by clinical studies should be standardized for different disease conditions through the development of core outcome sets (COS).

METHODS

There is an international effort for reaching consensus on outcome measures and establishing COS that represent agreed-upon standardized collections of outcome measures that will be reported in all studies within a clinical area. Across clinical specialties, the Core Outcome Measures in Effectiveness Trials (COMET) initiative launched in 2010. In 2014, the editors of women's health journals answered the challenge of COMET and formed the Core Outcomes in Women's Health initiative. The Journal of Lower Genital Tract Diseases is a participating member of the Core Outcomes in Women's Health consortium.

RESULTS

There is broad inconsistency in outcome measures and reporting in the field of lower anogenital tract diseases. No core outcome sets currently exist. Suggested target conditions in anogenital disease are vulvar dermatoses, cervical intraepithelial neoplasia, and vulvodynia.

CONCLUSIONS

Investigators are encouraged to conduct secondary systematic research to determine previously reported primary outcome measures and suggest domains for COS. Core Outcomes in Women's health initiative and COMET encourage the formation of consensus panels of stakeholders (researchers, health care providers, patients, and others) to recommend outcome domains and COS and then publish their report.

Evidence-based (S3) Guideline on (anogenital) Lichen sclerosus

Lichen sclerosus (LS) is an inflammatory skin disease that usually involves the anogenital area. All patients with symptoms or signs suspicious of lichen sclerosus should be seen at least once initially by a physician with a special interest in the disease in order to avoid delay in diagnosis, as early treatment may cure the disease in some and reduce or prevent scarring. The diagnosis is made clinically in most cases. Biopsies should only be performed under certain circumstances. The gold standard for treatment remains potent to very potent topical steroids; however, mild and moderate disease in boys and men may be cured by circumcision. Certain triggers should be avoided. http://www.euroderm.org/images/stories/guidelines/2014/S3-Guideline-on-Lichen-sclerosus.pdf http://www.awmf.org/fachgesellschaften/mitgliedsgesellschaften/visitenkarte/fg/deutsche-gesellschaft-fuer-gynaekologie-und-geburtshilfe-dggg.html.

Avocado and soybean extracts as active principles in the treatment of mild-to-moderate vulvar lichen sclerosus: results of efficacy and tolerability

OBJECTIVE

Limited evidence is available on the effectiveness of treatments alternative to corticosteroids for vulvar lichen sclerosus (VLS). The present study aimed to assess the efficacy and tolerability of avocado and soybean extracts (ASE) as active principles of both a topical product and a nutritional supplement in the treatment of active mild-to-moderate VLS.

MATERIALS AND METHODS

Twenty-three patients were enrolled. Treatment consisted of a topical product containing ASE and other lenitive and anti-oxidant principles administered twice daily for 24 weeks, in association with a dietary supplement containing ASE, vitamin E and para-aminobenzoic acid for the first 12 weeks. The primary efficacy endpoint was the rate of patients achieving an improvement from baseline in global subjective score (GSS) and global objective score (GOS) of ≥ 75%. Secondary efficacy endpoint was the rate of patients achieving GSS50 and GOS50. Tertiary efficacy endpoint was the mean reduction in subjective and objective scores throughout the treatment.

RESULTS

By the end of the 24-week treatment, 12 (70.5% of symptomatic patients) and 13 patients (72.2%) achieved an improvement of at least 75% in subjective and objective global scores, respectively; 100% and 88.9% reached GSS50 and GOS50, respectively. Mean symptom and sign scores decreased significantly after treatment. The treatment was well tolerated.

CONCLUSIONS

Our results provide evidence that the topical and dietary supplements used in the study, which contain active principles exerting anti-inflammatory, anti-fibrotic, emollient and lenitive actions, are effective alternatives in the treatment of symptoms and signs of mild-to-moderate VLS.

Spanish consensus on vulvar disorders in postmenopausal women

INTRODUCTION

The consequences of vulvar disorders in terms of health, sexuality, and quality of life are usually undervalued, with disparities in the conceptual, diagnosis and treatment criteria.

AIM

The objective of this guide will be to analyse the factors associated with the diagnosis and treatment of vulvar disorders and to provide recommendations for the most appropriate diagnostic and therapeutic measures.

METHODOLOGY

A panel of experts from various Spanish scientific societies related to sexual health (Spanish Menopause Society [SMS] and the Asociación Española de Patología Cervical y Colposcopia [AEPCC]) met to reach a consensus on these issues and to decide the optimal timing and methods based on the best evidence available.

RESULTS

We recommend a biopsy of all vulvar lesions with an uncertain diagnosis, especially with asymmetry, irregular borders, variegated and irregular colour and diameter >6mm. For vulvodynia, we recommend the use of lubricants or topical treatments with lidocaine or bupivacaine, amitriptyline, baclofen or triamcinolone. For vulvar epithelial disorders, we recommend beginning with topical corticosteroids of moderate to high potency. For sexual dysfunction, a multidisciplinary approach is the best management strategy in these patients.

Growing evidence for topical mometasone fuoroate in the treatment of Vulvar Lichen Sclerosus

Vulvar lichen sclerosus (VLS) is a chronic inflammatory disease with a huge impact on a person's quality of life. On the basis of the immunologic changes in VLS, treatment with a high potency topical corticosteroid is recommended. The currently available guidelines identified the ultra-potent corticosteroid clobetasol propionate 0.05% (CP) as the first-line recommended treatment but growing evidence supports the use of the potent corticosteroid mometasone furoate 0.1% (MMF). We reviewed the available studies assessing MMF in the treatment of VLS. Both non comparative and comparative studies were included in this review. Findings from clinical trials indicate that MMF is an effective and safe option in the treatment of VLS both in the active phase and in long-term maintenance treatment. Consistent with the findings from the comparative studies, MMF shows similar efficacy and safety to CP.

Clinical guidelines for gynecologic care after hematopoietic SCT. Report from the international consensus project on clinical practice in chronic GVHD

Despite similarities relevant age- and gender-specific issues exist in the care of patients after allogeneic hematopoietic SCT (HSCT). Female genital chronic GVHD (cGVHD) has been markedly underreported in the past but has a significant impact on the patients' health and quality of life. Data on prevention and treatment of this complication are still limited. Here we present a comprehensive review summarizing the current knowledge, which was discussed during several meetings of the German, Austrian and Swiss Consensus Project on clinical practice in cGVHD. In this report, we provide recommendations for post-transplant gynecological care of cGVHD manifestations agreed upon by all participants. This includes guidelines for diagnosis, prevention, and therapeutic options and topical treatments in female patients with genital cGVHD and hormonal replacement treatment of premature ovarian failure for adult and pediatric patients and underlines the necessity for regular gynecological care and screening programs for women after HSCT.

Vulvar dermatosis

Vulvar dermatoses are inflammatory conditions responsible for chronic or recurrent itching and soreness. The lesions are either circumscribed to the vulva or associated with extragenital localizations which may help to assess the diagnosis. They should be differentiated from infectious or neoplastic diseases which may have clinical similarities. As opposed to the majority of all dermatoses that have a benign and regular course, lichen sclerosus or lichen planus could exceptionally foster the occurrence of an epithelial cancer precursor which may evolve to squamous cell carcinoma. Topical corticosteroids are the mainstay treatment of vulvar dermatosis. We do not know if the treatment of vulvar lichen sclerosus and vulvar lichen planus prevents squamous cell carcinoma.
