ABSTRACT

Importance: A recent expert consensus exercise emphasized the importance of developing a global network of patient registries for alopecia areata to redress the paucity of comparable, real-world data regarding the effectiveness and safety of existing and emerging therapies for alopecia areata. Objective: To generate core domains and domain items for a global network of alopecia areata patient registries. Evidence Review: Sixty-six participants, representing physicians, patient organizations, scientists, the pharmaceutical industry, and pharmacoeconomic experts, participated in a 3-round eDelphi process, culminating in a face-to-face meeting at the World Congress of Dermatology, Milan, Italy, June 14, 2019. Findings: Ninety-two core data items, across 25 domains, achieved consensus agreement. Twenty further noncore items were retained to facilitate data harmonization in centers that wish to record them. Broad representation across multiple stakeholder groups was sought; however, the opinion of physicians was overrepresented. Conclusions and Relevance: This study identifies the domains and domain items required to develop a global network of alopecia areata registries. These domains will facilitate a standardized approach that will enable the recording of a comprehensive, comparable data set required to oversee the introduction of new therapies and harness real-world evidence from existing therapies at a time when the alopecia areata treatment paradigm is being radically and positively disrupted. Reuse of similar, existing frameworks in atopic dermatitis, produced by the Treatment of Atopic Eczema (TREAT) Registry Taskforce, increases the potential to reuse existing resources, creates opportunities for comparison of data across dermatology subspecialty disease areas, and supports the concept of data harmonization.

ABSTRACT

BACKGROUND: Frontal fibrosing alopecia (FFA) is a chronic cicatricial alopecia with unknown etiology and a worldwide rising incidence. OBJECTIVE: The objective of this study was to evaluate the association of FFA with demographic and exposure factors in a Brazilian multiracial population. METHODS: A multicenter case-control study was conducted in 11 referral centers throughout Brazil. The study was a case-control study that prospectively recruited 902 participants (451 patients with FFA and 451 sex-matched control individuals). Study participants completed a thorough questionnaire comprising variables grouped as baseline demographics, environmental exposure, diet, hormonal factors, allergies, and hair and skin care. RESULTS: When adjusted by sex, age, menopause, and skin color, FFA was associated with hair straightening with formalin (odds ratio [OR], 3.18), use of ordinary (nondermatologic) facial soap (OR, 2.09) and facial moisturizer (OR, 1.99), thyroid disorders (OR, 1.69), and rosacea (OR, 2.08). Smokers (OR, 0.33) and users of antiresidue/clarifying shampoo (OR, 0.35) presented a negative association with FFA. There was no association with the use of sunscreen. LIMITATIONS: Recall bias. CONCLUSIONS: The association with moisturizers, ordinary facial soap, and hair straightening with formalin and the negative association with antiresidue/clarifying shampoo reinforce the possibility of an exogenous particle triggering FFA.

ABSTRACT

BACKGROUND: Alopecia areata is a highly frequent disease with an impact on quality of life and several treatment options with little clinical confirmatory evidence. OBJECTIVE: To disseminate the recommendations of Brazilian dermatologists with expertise in the treatment of alopecia areata. METHODS: Eight specialists with expertise in alopecia areata from different university centers were appointed by the Brazilian Society of Dermatology to reach a consensus on its treatment. Based on the adapted DELPHI methodology, the relevant elements were considered; then, an analysis of recent literature was carried out and the consensus was written down. Consensus on the management of alopecia areata was defined with the approval of at least 70% of the panel. RESULTS/CONCLUSIONS: Intralesional injectable corticotherapy was considered the first option for localized disease in adults. In extensive cases with signs of activity, systemic corticosteroid therapy should be considered and can be used together with immunosuppressants (corticosteroid-sparing agents). The use of an immunosensitizer (diphencyprone) is an option for stable long-term cases. Evaluation of side effects is as important as the rate of hair regrowth.

ABSTRACT

Dissecting cellulitis is a chronic, progressive, and relapsing inflammatory disease that predominantly affects the vertex and occiput of young Afro-descendent men. It starts with papules and pustules that evolve to nodules, abscesses, and cicatricial alopecia. This article illustrates the evolutive trichoscopy of dissecting cellulitis, from its early phase, through the abscess phase, to the fibrotic cicatricial phase. Trichoscopy complements clinical-pathological classification, representing a complementary tool useful in early diagnosis and monitoring of the patient during treatment.

ABSTRACT

BACKGROUND: Frontal fibrosing alopecia (FFA) is considered a variant of lichen planopilaris affecting mainly the frontotemporal hairline. Since the first report in 1994, several other clinical features have been associated with the disease, such as facial papules (FP). Even though FP have been linked to facial vellus hair follicle involvement, how this finding alone could lead to the formation of clinically evident FP in FFA patients had not yet been addressed. OBJECTIVE: To describe histopathological findings of FP in the context of FFA and to highlight features that may be linked to their clinical formation. METHODS: Cutaneous FP biopsies of FFA patients performed between January 2016 and May 2017 were retrieved from our pathology database and reexamined by 2 pathologists. RESULTS: Histological sections of thirteen 3.0-mm punch biopsy specimens (2 horizontally and 11 vertically oriented) were collected from 7 patients. Eleven specimens demonstrated prominent sebaceous glands and 10 dilated sebaceous ducts. Pinkus acid orcein staining revealed reduction and fragmentation of the elastic fibers in 12 samples and, in 7 of these, this finding was observed in both the papillary and reticular dermis, particularly around sebaceous lobules. Vellus hair follicle involvement was only seen in 2 samples. CONCLUSIONS: Prominent sebaceous lobules with dilated ducts associated with an abnormal elastic framework seem to be the main explanation for the formation of FP in the context of FFA.

ABSTRACT

Intralesional corticosteroid (IL-CS) injections have been used to treat a variety of dermatological and nondermatological diseases. Although an important therapeutic tool in dermatology, a number of local side effects, including skin atrophy, have been reported following IL-CS injections. We recently noticed that a subset of patients with steroid-induced atrophy presented with ivory-colored areas under trichoscopy. We performed a retrospective analysis of trichoscopic images and medical records from patients presenting ivory-colored areas associated with atrophic scalp lesions. In this paper, we associate this feature with the presence of steroid deposits in the dermis and report additional trichoscopic features of steroid-induced atrophy on the scalp, such as prominent blood vessels and visualization of hair bulbs.

ABSTRACT

BACKGROUND: Nail psoriasis may affect up to 90% of patients with psoriasis in the course of the disease throughout their lives and it is often a therapeutic challenge to dermatologists. Topical treatments described in the literature have demonstrated variable efficacy, and unsatisfactory results have been associated to inefficient penetration of the active ingredient into the nail plate and proximal nail fold. Recently the use of clobetasol on nail lacquer vehicle has been suggested, with satisfactory results and no side effects. OBJECTIVE: To determine the efficacy and safety of clobetasol in nail lacquer vehicle in three concentrations (0.05%, 1% and 8%) in patients with nail psoriasis. METHODS: Prospective, controlled, randomized pilot study in fifteen patients with nail bed and/or nail matrix psoriasis in both hands, subdivided into three groups: A(0.05% clobetasol nail lacquer), B(1% clobetasol nail lacquer) and C(8% clobetasol nail lacquer). All groups used clobetasol nail lacquer on the left hand and base coat nail lacquer as control on the right, twice a week for 16 weeks. Clinical evaluation was done by photographic records and the NAPSI score of both treated and control hands, as well as modified NAPSI score of the most affected nail of the treated hand. RESULTS: Group C showed a statistically relevant clinical response compared to the other groups, reflected in the improvement of clinical parameters, of treated hand NAPSI score, when compared to the control hand, and modified NAPSI score of the most affected nail in the treated hand. CONCLUSION: The 8% clobetasol nail lacquer was effective and safe, and it can be considered a good option of topical therapy in the treatment of nail psoriasis.

FUNDAMENTOS: A psoríase ungueal, de difícil manejo terapêutico, pode afetar até 90% dos portadores de psoríase no transcurso da doença, ao longo de suas vidas. Os tratamentos tópicos descritos na literatura têm eficácia variável, muitas vezes com resultados insatisfatórios causados pela ineficiência da penetração da substância ativa através da placa ungueal e dobra proximal. Recentemente tem sido proposto o uso do clobetasol em veículo esmalte, demonstrando resultados satisfatórios e ausência de efeitos colaterais. OBJETIVO: Determinar a eficácia e segurança do clobetasol em veículo esmalte em três concentrações (0,05%, 1% e 8%) nos pacientes com psoríase ungueal. MÉTODOS: Estudo piloto, prospectivo, controlado e randomizado com quinze pacientes portadores de psoríase ungueal em ambas as mãos. Os pacientes foram subdivididos em três grupos: A (esmalte clobetasol 0,05%), B (esmalte de clobetasol 1%) e C (esmalte de clobetasol 8%). Os pacientes usaram esmalte de clobetasol na mão esquerda e esmalte base (sem medicação - controle) na direita, aplicandoos duas vezes por semana, por 16 semanas. Fez-se a avaliação clínica por registros fotográficos e pelos MÉTODOS: NAPSI da mão tratada e controle e NAPSI modificado da unha mais acometida da mão tratada. RESULTADOS: O grupo C apresentou de forma estatisticamente significativa a resposta clínica mais relevante, refletida na melhora dos parâmetros clínicos, do NAPSI da mão tratada comparado ao da mão controle e do NAPSI modificado da unha mais acometida da mão tratada. CONCLUSÕES: Neste estudo piloto, o esmalte de clobetasol a 8% foi eficaz e seguro, mostrando-se uma boa opção de terapêutica tópica no tratamento da psoríase ungueal.

ABSTRACT

BACKGROUND: Dermoscopy is an important tool for the diagnosis of benign and malignant melanocytic diseases. Recently, this method has also been found to be extremely useful in the diagnosis and follow-up of alopecias. OBJECTIVE: The objective of this study was to describe dermoscopic findings in patients with clinical and histopathological characteristics of cicatricial alopecia. METHODS: A descriptive cross-sectional study was conducted in which 14 patients with cicatricial alopecia were selected based on clinical and histopathological evaluation of the scalp. The underlying cause was classic lichen planopilaris in four cases, frontal fibrosing alopecia in five and discoid lupus erythematosus in the remaining five. The patients were evaluated using videodermoscopy and conventional dermoscopy (with a handheld dermoscope), performed independently by three different examiners. Magnification ranged from 10x to 70x. RESULTS: Principal findings in cases of discoid lupus erythematosus were: white patches, branching capillaries, keratin plugs and areas of reduced follicular ostia; in classic lichen planopilaris: perifollicular scales, white dots and reduced follicular ostia; and in frontal fibrosing alopecia: reduced follicular ostia, perifollicular scales, perifollicular erythema and branching capillaries. The blue-grey dots described in this paper were a novel feature in scalp dermoscopy. CONCLUSIONS: The use of dermoscopy for the clinical evaluation of the scalp in cases of cicatricial alopecia improves diagnostic capacity beyond simple clinical inspection and reveals novel features of the disease.

ABSTRACT

Hair abnormalities observed in epidermolysis bullosa (EB) are of variable severity and include mild hair shaft abnormalities, patchy cicatricial alopecia, cicatricial alopecia with a male pattern distribution, and alopecia universalis. Alopecia is usually secondary to blistering, and scalp areas more exposed to friction, such as the occipital area, are involved more frequently. This article reviews the hair abnormalities reported in the different subtypes of EB.
