Vulvar lichen sclerosus (VLS) is a chronic inflammatory skin disease of the anogenitalarea leading to itch, burning, sexual dysfunction and impaired quality of life. An unmet need in the context of LS is a practical, easily assessable grading scale to classify disease severity and to allow intra- and interindividual comparisons. The objectives of this study were i) to assess the prevalence and severity of 23 items proposed by a recent Delphi consensus group in patients with adult VLS. ii) to develop a clinical severity scale and, iii) to test the interrater reliability of this novel severity scale. A retrospective assessment of the prevalence and severity of 23 items in 143 patients was performed by using patient records and photo documentation to develop a novel clinical severity scale (i.e. the "Clinical Lichen Sclerosus Score" = CLISSCO) for VLS. Thereafter, the CLISSCO was validated by 16 raters. We found that the items proposed by the consensus group vary markedly in frequency and severity. Following selection of the most relevant items, the CLISSCO was developed consisting of 3 "Symptoms", 3 "Signs" and 6 "Architectural changes" rated on a 0-4 point Likert-scale. The intraclass correlation coefficient was excellent for each item, the applicability of the CLISSCO considered user-friendly by the raters. We conclude that the CLISSCO proved to be a user-friendly, reliable tool to assess disease severity in VLS. However, further studies are needed to validate its applicability and value in daily practice and clinical research., (© 2021 Wiley Periodicals LLC.)

In the era of staggering speed in development of the novel coronavirus disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we have reviewed the dermatologists' tools at hand for their utility (and potential risks) in patients affected by COVID-19. This review aims to shed light on the antiviral and proviral potential of drugs routinely used in dermatology to modulate COVID-19. The literature search included peer-reviewed articles published in the English language (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) from January 1990 to March 2020 and by reference lists of respective articles. Somewhat to our surprise, we have found that several of our drugs widely used in dermatology have antiviral potential. On the other hand, we also frequently use immunosuppressive drugs in our dermatologic patients that potentially pose them at increased risk for COVID-19., (© 2020 Wiley Periodicals LLC.)

The traditional patient-physician relationship is being changed by the patients' searches for medical information on the Internet and in social media (SM). Freely available medical information online bears enormous potential but also holds dangers. In this cross-sectional, questionnaire-based study, the patients' motivation, preferences and unmet needs when searching for medical information online and the impact on the patient-physician relationship were assessed using Spearman's correlation coefficients, χ 2 -tests and paired t-tests. Among 460 participants, 82.4% had already used the Internet/SM to gain medical information, but in only 9.4% their dermatologists had raised this topic. Online search for medical information was associated with female gender (P = .048), a higher skin-related burden (P = .020), higher level of education (P = .072), higher income (P = .019), anxiety (P = .004), and adnexal skin diseases (P = .043). For 16.1% of patients, "the Internet/SM" was their most important source of medical information; 81.4% deemed the impact of their online searches on their patient-physician relationship as neutral, 16.0% as positive, 2.6% as negative. The patients' top three unmet needs were "Online consultations", "Professional content on YouTube" and "Chat opportunities". Online search for medical information is a very important topic for most dermatology patients but it may not be adequately addressed by dermatologists. Our results indicate that from the patients`perspective such online searches do not have a significant impact on patient-physician relationship., (© 2020 Wiley Periodicals LLC.)

Dehydrated human amnion/chorion membrane allograft (dHACM) derived from placenta is increasingly used for skin and soft tissue repair in several medical specialties. Promising effects of dHACM were also reported in chronic venous and diabetic leg ulcers. However, dHACM is cost-intensive and its effect on chronic leg ulcers of other etiologies and pain reduction is unknown. Clinical predictors of a favorable response to dHACM during the early treatment period could help to limit unnecessary costs. In our case series with six patients suffering from chronic lower leg ulcers of various etiology, the effect of dHACM once per week on reduction of pain and wound size during a 5-week period was examined. dHACM resulted in effective pain reduction and improved wound healing in three patients with chronic leg ulcers due to calciphylaxis, chronic venous disease and reactive angioendotheliomatosis. Pain reduction after 1 to 2 applications of dHACM predicted a favorable healing response. Hence, our observation indicates that assessment of pain 3 weeks after initiation of dHACM may be a clinical predictor to justify dis-/continuation of dHACM and thereby may help to limit costs., (© 2020 Wiley Periodicals LLC.)

Itch is the commonest skin-related symptom and can be influenced by visual cues as exemplified by the phenomenon of "contagious itch." Colors are visual cues able to modify somatosensory inputs. We explored the relationship of colors and itch and the impact of color viewing on itch intensity. In this cross-sectional study, patients suffering from itch with a mean intensity of ≥2 on a Numerical Rating Scale during the last 7 days were evaluated. The study consisted of a questionnaire-based part using The Manchester Color Wheel and the ItchyQoL, followed by an interventional part. All 72 itch patients were able to match their itchy sensation with a color: In 68 patients (94.4%) this "pruritic" basic color was red. Likewise, all patients were able to define a subjective "antipruritic" color: The leading basic color choice was blue (31/72, 43.0%) followed by green (21/72, 29.1%), yellow (7/72,9.7%) and others. The impairment of the itch-related quality of life (as measured by the ItchyQoL) correlated with the brightness and saturation of the pruritic and antipruritic colors. Ten patients were visually exposed to their subjective antipruritic and pruritic color during 10 minutes resulting in a significant decrease and increase of itch intensity compared to baseline (5.1 ± 1.52 vs. 2.8 ± 1.47 [0-10 Numerical Rating Scale, NRS], p=0.0004 and 4.9 ± 1.66 vs. 6.8± 2.09 NRS, p=0.0009). These results indicate that itch can be modified by color viewing and colors matter when treating itch patients. However, further investigations are required to elucidate the therapeutic potential of colors in itch patients., (© 2020 Wiley Periodicals LLC.)

Itch is the most bothersome symptom in psoriasis, often leading to impaired quality of life. Treatment of psoriasis-induced itch is frequently unsatisfactory as the various therapies employed have a delayed onset of effect. Histamine-1 receptor (H1) antihistamines are not recommended in treatment guidelines as histamine is not considered a key mediator in psoriasis. However, patients using H1 antihistamines frequently report benefits in questionnaire-based studies. To address these contradictions, we examined the short-term effects of levocetirizine, a nonsedating H1 antihistamine, on psoriasis-related itch and itch-related quality of life. In this pilot study, patients with psoriasis-related itch received levocetirizine 5-10 mg daily as a concomitant treatment for 5 days. Change of itch intensity as measured by hourly itch ratings and the change of itch-related quality of life were measured at different time points. A total of 29 of 30 patients (96%) reported a decline in itch within 5 days. Mean itch reduction was 23% after Day 1 (p = .005), 40% after Day 3 (p < .001), and 41% after Day 5 (p < .001). Furthermore, itch-related quality of life also significantly improved after 5 days (p < .001). Only 2 of 30 patients (6.7%) reported mild sleepiness. Levocetirizine 5-10 mg daily as an add-on therapy seems to be an effective treatment to improve itch and itch-related quality of life within only a few days., (© 2019 Wiley Periodicals, Inc.)
