Outcome Measures in Adult Vulvar Lichen Sclerosus:A Case Series of Women Diagnosed as Juveniles
OBJECTIVES: Studies on the consequences of juvenile vulvar lichen sclerosus (JVLS) in adulthood are limited. A number of measuring tools are available for analyzing adult vulvar lichen sclerosus (VLS), but these have not been applied in studies on JVLS. The aim is to study physical findings, quality of life, sexual well-being, and self-image in adult women with a history of juvenile VLS. MATERIALS AND METHODS: Adult women with a biopsy proven history of JVLS were recruited to be examined and surveyed using available standardized measurement tools. This took place in an outpatient setting by physicians who were not involved in the treatment of participants. RESULTS: Twenty-seven women (median age 29 years) with a history of JVLS and median time since biopsy of 19.5 years were recruited. Of these women, 59% currently had symptoms, 63% had signs of active disease, and 85% had moderate to severe architectural changes. Despite these residual signs, vulvar specific-quality of life and vulvar self-image scored favorably while generic health-related quality of life was somewhat effected. CONCLUSIONS: JVLS has consequences in adulthood involving physical findings and vulvar quality of life. The use of standardized outcome measures for clinical practice and research purposes facilitates a better understanding of the sequelae to JVLS.</p
Dermatoscopy and Optical Coherence Tomography in Vulvar High-Grade Squamous Intraepithelial Lesions and Lichen Sclerosus:A Prospective Observational Trial
Objective This study aimed to examine potential discriminatory characteristics of dermatoscopy and dynamic optical coherence tomography (D-OCT) on vulvar high-grade squamous intraepithelial lesions (vHSIL) and lichen sclerosus (LS) compared with healthy vulvar skin. Methods A prospective observational clinical trial was performed in 10 healthy volunteers, 5 vHSIL and 10 LS patients. Noninvasive imaging measurements using dermatoscopy and D-OCT were obtained at several time points, including lesional and nonlesional vulvar skin. Morphologic features of vHSIL and LS were compared with healthy controls. Epidermal thickness and blood flow were determined using D-OCT. Patients reported tolerability of each study procedure, including reference vulvar biopsies. The main outcome measures were feasibility and tolerability of imaging modalities, dermatoscopy and OCT characteristics, OCT epidermal thickness and D-OCT dermal blood flow. Results The application of dermatoscopy and D-OCT is feasible and tolerable. In vHSIL, dermatoscopic warty structures were present. In LS, sclerotic areas and arborizing vessels were observed. Structural OCT in the vulvar area aligned with histology for hyperkeratosis and dermal-epidermal junction visualization. Currently, the OCT algorithm is unable to calculate the epidermal thickness of the uneven vulvar area. Dynamic optical coherence tomography showed statistically significant increased blood flow in LS patients (mean ± SD, 0.053 ± 0.029) to healthy controls (0.040 ± 0.012; p =.0024). Conclusions The application of dermatoscopy and D-OCT is feasible and tolerable in vHSIL and LS patients. Using dermatoscopy and D-OCT, the authors describe potential characteristics to aid differentiation of diseased from healthy vulvar skin, which could complement clinical assessments.</p
Comparison of lichen sclerosus in boys and girls: A systematic literature review of epidemiology, symptoms, genetic background, risk factors, treatment, and prognosis
Background: Studies concerning pediatric lichen sclerosus are limited, and, to date, there have been no studies comparing the course of lichen sclerosus in boys and girls. We sought to examine all publications on boys and girls with lichen sclerosus and assess and compare epidemiology, symptoms and signs, genetic background, risk factors, treatment, and prognosis. Methods: A systematic search was performed in the Embase, Medline, Cochrane, and Web of Science databases. Inclusion criteria were information on children ages 0–18 years and a clinical or histologic diagnosis of lichen sclerosus. Literature from 1985 to 2021 was reviewed. Results: A total of 1780 articles were retrieved from the search, of which 90 articles were eligible for inclusion. Boys and girls present similarly on many aspects; nonetheless, treatment and follow-up are approached differently. Conclusions: Though the clinical approach is often different, lichen sclerosus in boys and girls demonstrates many similarities. More research is needed, especially on follow-up, to gain a better understanding of the course of lichen sclerosus and establish an advanced management plan for children
A case of leprosy in an immunocompromised traveller
Case presentationA 63-year-old man, born and living in The Netherlands, presented with a one-and-half year history of polyneuropathic burning pain and swelling involving the distal extremities which made walking difficult, development of a pressure ulcer on the fifth toe of the right foot and progressive fatigue and weight loss. He also reported a reddish/purple rash on his trunk and legs which had been present for a few months. He had a medical history of allergic asthma and hypereosinophilic syndrome for which he was using prednisone 10 mg/day for 24 years and mepolizumab, a monoclonal antibody to IL-5, for the last 2 years. The dose of prednisone was recently reduced to 5 mg/day. Furthermore, he had hypopigmentated skin lesions diagnosed as vitiligo nine years previously. The patient’s travel history included two trips to the Moluccas in Indonesia (three and fifteen years ago), visiting friends and relatives. He also travelled for months to several countries in Southern Africa 9 and 11 years ago to play music with a band in rural villages

The NLR SkinApp:Testing a Supporting mHealth Tool for Frontline Health Workers Performing Skin Screening in Ethiopia and Tanzania
Background: The prevalence of skin diseases such as leprosy, and limited dermatological knowledge among frontline health workers (FHWs) in rural areas of Sub-Saharan Africa, led to the development of the NLR SkinApp: a mobile application (app) that supports FHWs to promptly diagnose and treat, or suspect and refer patients with skin diseases. The app includes common skin diseases, neglected tropical skin diseases (skin NTDs) such as leprosy, and HIV/AIDS-related skin conditions. This study aimed to test the supporting role of the NLR SkinApp by examining the diagnostic accuracy of its third edition.Methods:A cross-sectional study was conducted in East Hararghe, Ethiopia, as well as the Mwanza and Morogoro region, Tanzania, in 2018–2019. Diagnostic accuracy was measured against a diagnosis confirmed by two dermatologists/dermatological medical experts (reference standard) in terms of sensitivity, specificity, positive predictive value, and negative predictive value. The potential negative effect of an incorrect management recommendation was expressed on a scale of one to four. Results: A total of 443 patients with suspected skin conditions were included. The FHWs using the NLR SkinApp diagnosed 45% of the patients accurately. The values of the sensitivity of the FHWs using the NLR SkinApp in determining the correct diagnosis ranged from 23% for HIV/AIDS-related skin conditions to 76.9% for eczema, and the specificity from 69.6% for eczema to 99.3% for tinea capitis/corporis. The inter-rater reliability among the FHWs for the diagnoses made, expressed as the percent agreement, was 58% compared to 96% among the dermatologists. Of the management recommendations given on the basis of incorrect diagnoses, around one-third could have a potential negative effect. Conclusions: The results for diagnosing eczema are encouraging, demonstrating the potential contribution of the NLR SkinApp to dermatological and leprosy care by FHWs. Further studies with a bigger sample size and comparing FHWs with and without using the NLR SkinApp are needed to obtain a better understanding of the added value of the NLR SkinApp as a mobile health (mHealth) tool in supporting FHWs to diagnose and treat skin diseases.</p
