    Abstract This work reports 30 cases of folliculitis decalvans (FD) in patients with dystrophic epidermolysis bullosa (DEB) among a cohort of 125 DEB patients seen between 2010 and 2021 in 2 French expert centers for the management of inherited epidermolysis bullosa. Such an association between two rare diseases cannot be fortuitous and implies a physiopathological link that we discuss in this paper. This association is a new significant fact to add to the reflexion on FD causes, suggesting that skin abnormality of DEB could act as a factor of a specific skin barrier alteration which could favor FD. Scarring alopecia with tufted folliculitis and pustules on inflamed skin at the vertex of a woman with dominant dystrophic epidermolysis bullosa.

    Abstract Alopecia areata (AA), an autoimmune disease -affecting the hair of the scalp, face, and/or body, can entail substantial psychological and physical burden for patients. There is currently no international agreement on how to treat AA and the approach may vary across countries. This study investigated the management of AA in clinical practice. Data from a point-in-time survey conducted in France, Germany, Italy, Spain, and the United Kingdom, between October 2021-June 2022, were analysed for adults with mild, moderate, and severe AA, based on physician assessment. Dermatologists were surveyed about factors used to assess disease severity, physician-reported treatment goals, and treatment patterns for AA, including the use of wigs. In total, 239 dermatologists reported on 2,083 patients. Physicians' severity assessment and treatment goals were predominantly driven by scalp hair loss. Topical and intralesional corticosteroids were the most prescribed treatments for mild and moderate AA. Conventional immunosuppressants, oral Janus kinase inhibitors, and topical immunotherapy use generally increased with AA severity and therapy line. Wig use was greatest for severe AA. The primary reasons for the last treatment change in the moderate and severe groups were worsening of condition, lack of initial efficacy, and loss of response, and for mild group were improvement in condition, lack of initial efficacy, and worsening of condition. Findings were generally similar across countries. This analysis provides insights into the management of AA in five European countries and confirms the need for more effective therapies, especially for patients with severe AA.

    Abstract Background: Androgenetic alopecia (AGA) is a pathology involving the aesthetic prognosis. Hair transplantation is among best treatments. The principle of hair micro-grafts during AGA consists in taking hair from the non-androgen-dependent occipital area to transplant them with their root in the sparse androgen-dependent areas. Herein, we report 10 cases of the different types of post-transplant inflammatory complications.
    Materials and methods: We included patients referred to our center by their dermatologists or hair transplant surgeons for inflammatory cicatricial alopecia or hair loss observed after the hair transplant.
    Results: Ten patients (eight men and two women) were included. These patients represented 0.08% of all consultations in our center. The indication for hair transplantation was AGA in all of our patients. The technique used for the transplant was follicular unit extraction (FUE) in seven cases and follicular unit transplantation (FUT) strip in three cases. None of the patients had pathology of the scalp or an inflammatory dermatosis before the operation. The inflammatory complications found were lichen planopilaris (LPP) in seven cases, erosive pustulosis of the scalp (EPS) in two cases, and superficial folliculitis (SF) in 1 case.
    Conclusion: Our series highlight the rarity of inflammatory complications that occur after a hair transplant. We demonstrate through this work that a hair transplant can trigger inflammatory pathology a few months after the act. We show also, the importance of detecting the rough forms of lichen before an intervention, hence the interest of the systematic dermatoscopic examination during the preoperative consultation.

    Abstract Introduction: Seborrheic dermatitis (SD) is a chronic, relapsing, inflammatory disorder of the head and trunk.
    Objectives: To explore the potential of a 1% Selenium disulphide (SeS2)-based shampoo to prevent relapses of scalp SD (SSD) following corticosteroid/salicylic acid (TCS/SA) treatment.
    Materials & methods: After a 2-week treatment with TCS/SA, adult patients with moderate-to-severe SSD received either the SeS2-based shampoo or its vehicle for eight weeks in a randomized, double-blinded fashion. Visits took place at baseline, weeks 2, 6 and 10. SSD severity was assessed based on erythema, flakes and pruritus; patients assessed the severity of pruritus. Global investigator and patient satisfaction were assessed at week 10.
    Results: Forty-eight adults were included. After four and eight weeks of post TCS/SA maintenance regimen, 8.1% and 16.7% in the SeS2, and 41.7% and 54.2% in the vehicle group relapsed, respectively. First median time-to-relapse in the vehicle group was 56 days; this was not reached for SeS2. After two weeks of TCS/SA, the prevalence of patients with no pruritus was 29.2% in the SeS2 group, and 41.7% in the vehicle group; it increased to 76.2% with SeS2 and to 57.1% with the vehicle at the end of the study. The clinical benefit of treatment with TCS/SCA was maintained in the SeS2 group only. Investigators and patients were highly satisfied with the efficacy of SeS2. Tolerance to SeS2 was excellent, with no reported adverse events.
    Conclusion: The SeS2-based shampoo significantly reduces the time-to-relapse of moderate-to-severe SSD flares. Its tolerance was excellent, with no reported adverse events.

    Abstract Introduction: Alopecia areata (AA) can negatively affect quality of life (QoL) and is associated with increased prevalence of anxiety and depression (vs people without AA). This study compared physician-assessed and patient self-rated severity of AA in a European sample and described the patient-reported burden of AA stratified by physician-assessed severity.
    Methods: Real-world data were collected from the Adelphi Real World AA Disease Specific Programme™, a retrospective point-in-time cross-sectional survey of dermatologists and their adult patients with AA in five European countries (France, Germany, Italy, Spain, UK). Physicians provided clinical data and an AA severity assessment, according to their own definition of 'mild', 'moderate' and 'severe'. Patients were invited to provide their perception of AA severity and completed patient-reported outcome (PRO) questionnaires, including Skindex-16 for AA (Skindex-16 AA), EuroQol-5-dimension questionnaire 5-level (EQ-5D-5L), Hospital Anxiety and Depression Scale and the Work Productivity and Activity Impairment Questionnaire.
    Results: Data for 2083 patients were collected by 239 physicians; 561 of these patients completed PRO questionnaires. In 78.5% of cases with available data (N = 549), there was alignment between patient and physician-rated AA severity (severity was rated higher by physicians in 15.7% of cases, by patients in 5.8% of cases). Data from all PRO instruments showed an increase in patient-reported burden and work and activity impairment with increasing physician-rated AA severity. For the Skindex-16 AA, the Emotions scale had the worst scores; anxiety/depression was the EQ-5D-5L dimension with the highest percentages of patients reporting any perceived problem.
    Conclusions: These data highlight the significant impact that AA can have beyond hair loss, especially for patients with severe AA. There was substantial physician-patient alignment on severity assessment. Higher physician-rated AA severity was associated with higher levels of patient-reported disease burden, including anxiety and depression, and work and activity impairment. These data may help inform appropriate treatment strategies.

    Abstract Introduction: Scalp psoriasis frequently goes with other disease location and may lead to a significant burden and impairment of quality of life (QoL). Adherence to local treatments is a frequent problem. A keratolytic and hydrating shampoo containing 2% salicylic acid, 5% urea, and 1% glycerin (active shampoo) has been developed for psoriasis-prone scalp.
    Objective: To assess the efficacy and tolerability of an active shampoo in subjects with mild to moderate scalp psoriasis.
    Materials and methods: A single-center, randomized, double-blind, vehicle-controlled study was conducted on 67 adults with mild to moderate psoriasis. The active shampoo or its vehicle were applied daily for 14 days and 3 times/week for another 14 days. Assessments included the Psoriasis Scalp Severity Index (PSSI), Investigator Global Assessment (IGA), calculated total surface affected hair, scalp greasiness, irritation, and assessed scalp dermatitis-specific quality-of-life issues using SCALPDEX and product acceptability.
    Results: The active shampoo significantly (p < 0.05) reduced the PSSI by 39.0%, 37.2%, 63.0%, and 69.0% immediately after washing compared to a 22.8%, 5.5%, 19.6%, and 13.0% with the vehicle at Days 1, 8, 15, and 30, respectively. SCALPDEX items, IGA, and irritation significantly (p < 0.05) reduced with the active shampoo. Hair and scalp greasiness improved continuously with both products until Day 21. Subject-reported symptom scores paralleled the positive evolution of clinical signs. The active shampoo was well tolerated, subjects were highly satisfied and had an improved QoL.
    Conclusion: The active shampoo significantly improved clinical signs, symptoms, and QoL of mild-to-moderate scalp psoriasis compared to the vehicle. It was very well tolerated and highly appreciated by the subjects.

    Abstract Background: Follicular hyperkeratosis along with hyperplasia of the follicular and interfollicular epithelia are major histopathological characteristics of hidradenitis suppurativa (HS). The presence of an occasional thickening of lesional skin in some folliculitis decalvans (FD) patients and histological similarities between FD and HS led us to look for epidermal hyperplasia and follicular hyperkeratosis in FD patients.
    Patients and method: We performed a retrospective histological analysis of 26 patients with FD.
    Objective: We sought to find out whether the presence of hyperplasia of the interfollicular epidermis and of the follicular epithelia could be verified in FD, with reference to the work of von Laffert et al. concerning HS.
    Results: The main quantitative and qualitative data were: follicular hyperkeratosis (77%), hyperplasia of the interfollicular epidermis (92%) with a psoriasiform aspect (88%), atrophy of the follicular epithelia (85%), plasma cells in infiltrate (92%) in large quantities (42%), follicular microcysts (60%), atrophy of the sebaceous glands (85%) and polytrichia (54%).
    Conclusion: Epidermal hyperplasia, sometimes psoriasiform and follicular microcysts, are significant histological signs of FD, which have been ignored until now although they seem very common.
