Dermatite de contato pigmentada por cosmético / Pigmented cosmetic contact dermatitis

A dermatite de contato pigmentada se destaca por sua raridade, sendo associada a inúmeros alérgenos cosméticos e têxteis. Acomete predominantemente mulheres de meia idade e fototipos altos. O teste de contato é imprescindível para a identificação do agente causal. O tratamento indicado consiste no afastamento do agente causal, no uso de fotoprotetores, clareadores tópicos e, por vezes, procedimentos dermatológicos abrasivos. Relatamos um caso de dermatite de contato pigmentada por cosmético motivado pela exuberância clínica e desfecho satisfatório, ressaltando a importância da suspeição diagnóstica e do manejo adequado impactando neste desfecho.

Pigmented contact dermatitis is a rare condition associated with numerous cosmetic and textile allergens. It predominantly affects middle-aged women with high phototypes. The patch test is essential to identify the causative agent. Treatment includes removal of the causative agent, sunscreen use, administration of topical bleaching agents, and occasionally abrasive dermatologic procedures. We report a case of pigmented cosmetic contact dermatitis motivated by its clinical exuberance and satisfactory outcome, emphasizing the importance of diagnostic suspicion and adequate management impacting this outcome.

Dermatite fotoalérgica ao pigmento azul de tatuagens: relato de um caso e breve revisão da literatura / Photoallergic dermatitis due to the blue pigment in tattoos: a case report and brief literature review

A prática de tatuagens é muito antiga e atualmente tornou-se extremamente popular, porém traz consigo riscos que não podem ser ignorados. As tintas utilizadas nas tatuagens são um fator importante para o aparecimento de reações adversas. A reação de hipersensibilidade aos pigmentos das tintas é uma das mais comuns. Entre elas, encontram-se reações alérgicas tipo dermatites de contato ou reações de fotossensibilidade, sendo esta última o motivo deste relato. O tratamento indicado é o uso de corticoides e a fotoproteção. Neste artigo, discorreremos especificamente sobre a reação de fotossensibilidade ao pigmento azul, com o relato de um caso e breve revisão da literatura.

Tattooing is a very old practice that has become extremely popular in recent years; however, it carries risks that cannot be ignored. The inks used in tattoos are an important factor for the appearance of adverse reactions. Hypersensitivity reactions to the pigments in the inks are some of the most common. These include allergic reactions such as contact dermatitis or photosensitivity reactions, the latter being the reason for this report. The recommended treatment is the use of corticosteroids and photoprotection. In this article, we will specifically discuss the photosensitivity reaction to the blue pigment with a case report and a brief literature review.

Spatial approach of leprosy in the State of São Paulo, 2009-2012

Abstract: Background: Leprosy is a chronic, infectious disease that affects the skin and the peripheral nervous system and can lead to permanent disability and/or deformity. Objectives: To identify the distribution and to quantify the spatial dependence of the detection rates of new cases of Hansen's disease in the State of São Paulo, correlating with socioeconomic variables. Methods: Ecological and exploratory study with data on the detection rates of new cases of Hansen's disease among residents of São Paulo State municipalities between 2009-2012. The average rate per 10,0000 inhabitants was estimated. Information on the proportion of the population with low-income and the values of the Gini index were obtained. Thematic maps were constructed with the average rates and with those obtained by the Bayesian estimator; Moran and Kernel maps were also constructed. Spatial analysis by TerraView program. An alpha of 5% was adopted. Results: In total, 7163 new cases of Hansen's disease were recorded throughout the state. The average rate per 10,000 inhabitants, was 0.71 (SD = 1.06), ranging from zero to 12.87, with higher rates in the west of the State, in the metropolitan area of the capital and the Paraiba Valley. Municipalities with high priority for intervention were located in the west and northwest of the State. There was no correlation between rates with Gini index and low income. Study limitations: Possible inconsistency of Hansen's disease notification database regarding information quantity, quality and processing. Conclusions: This study identified the distribution and quantified the spatial dependence of the detection rates of new cases of Hansen's disease in the State of São Paulo, corroborating previous studies and serving as a subsidy to health managers.

Fatores de crescimento e cicatrização: experiência em um serviço de Dermatologia / Growth factors and healing: experience in a Dermatology service

Introdução: A cicatrização é um fenômeno que ocorre após lesão tecidual e envolve mecanismos celulares e moleculares complexos. Os fatores de crescimento parecem ser um complemento eficaz e seguro no tratamento das feridas. Objetivo: Avaliar a cicatrização de feridas após eletrocoagulação, comparando-se o veículo isolado à sua associação com o fator de crescimento epidérmico. Métodos: Ensaio clínico duplo-cego em Serviço de Dermatologia entre 2016 e 2018. Incluídos pacientes de ambos os sexos, acima de 18 anos, submetidos à eletrocoagulação de duas lesões e posterior aplicação de veículo (cold cream) em uma e fator de crescimento epidermico em cold cream na outra. Avaliações com sete, 14 e 28 dias, analisaram: eritema, edema, crosta, secreção e cicatrização. Utilizou-se o teste binomial para duas proporções e o teste exato de Fisher para dados dicotômicos. Resultados: Em relação a eritema, edema, crosta e secreção foram encontrados resultados variáveis, ora favorecendo o veículo, ora o fator de crescimento, porém sem significância estatística. Quanto à cicatrização, a epitelização mostrou-se mais rápida com fator de crescimento epidermico (p<0,05). Conclusões: Os resultados deste estudo, que avaliou o impacto do fator de crescimento epidérmico no processo de cicatrização, corroboram os dados da escassa literatura atual e servem de base para estudos futuros.

Introduction: Healing is a phenomenon that occurs after tissue injury and involves complex cellular and molecular mechanisms. Growth factors seem to be an effective and safe complement for the treatment of wounds. Objective: To evaluate wound healing after electrocoagulation, comparing the vehicle in isolation and its association with epidermal growth factor. Methods: Double-blind clinical trial in a Dermatology service between 2016 and 2018. Patients of both genders, older than 18 years of age, submitted to electrocoagulation of two lesions and subsequent application of the vehicle (cold cream) on one and epidermal growth factor in cold cream on the other were included. Evaluations after 7, 14 and 28 days, analysed erythema, edema, crusting, discharge and healing. Analyzed: edema, edema, crusting, discharge and healing. The binomial test was used for two ratios and Fisher's exact test was used for dichotomic data. Results: Variable results were found regarding erythema, edema, crusting and discharge, sometimes favoring the vehicle, sometimes the growth factor, however with no statistical significance. Regarding healing, epithelialization was quicker with epidermal growth factor (p<0.05). Conclusions: This study evaluated the impact of epidermal growth factor in the healing process, and its results reinforce scarce data of the current literature and are a foundation for future studies.

Neutrophilic dermatosis of the dorsal hands: response to dapsone monotherapy

Abstract: Neutrophilic dermatosis of the dorsal hands is considered a rare and localized variant of Sweet's syndrome. Although the etiology is unknown, there are reports of association with infections, neoplasias, autoimmune diseases and medications. Histopathology shows a dense neutrophilic inflammatory infiltrate in the dermis. Treatment is based on the administration of systemic corticosteroids; however, a combination of medications is useful, given the frequency of relapses. The authors report a classic and clinically exuberant case of neutrophilic dermatosis of the dorsal hands, with excellent response to oral dapsone treatment, and offer a brief literature review.

Coexistência de psoríase e comorbidades relacionadas à síndrome metabólica / Coexistence of psoriasis with metabolic syndrome-related comorbidities

OBJETIVOS: Avaliar a coexistência da psoríase e comorbidades relacionadas à síndrome metabólica, e identificar a associação de características dessa dermatose (gravidade, forma clínica e tipo de tratamento) com essas comorbidades. MÉTODOS: Trata-se de um estudo transversal e descritivo de base hospitalar, envolvendo indivíduos com psoríase em acompanhamento em um ambulatório de referência, de 2014 a 2015, sem restrições para seleção dos mesmos. A análise dos dados, obtidos por meio de questionário, avaliação clínica e exames complementares, foi inicialmente descritiva e, posteriormente, por regressão logística univariada. RESULTADOS: Foram incluídos 59 indivíduos. Destes, 55,9% apresentaram obesidade abdominal, 72,9% hipertensão arterial e 62,7% redução da HDL-c. A presença de psoríase de maior gravidade (Índice de Gravidade da Psoríase por Área − PASI>10) indicou maior chance para a ocorrência de hipertensão arterial, elevação da glicemia e de triglicerídeos; pacientes com forma clínica não vulgar apresentaram maior chance para todas as comorbidades, exceto para elevação de triglicerídeos, e pacientes em uso de medicação sistêmica apresentaram maior chance para ocorrência de obesidade abdominal, elevação da glicemia e de triglicerídeos. CONCLUSÕES: Psoríase e comorbidades relacionadas à síndrome metabólica coexistiram. Possivelmente, as formas clínicas não vulgar, a psoríase grave e o tratamento sistêmico com essas comorbidades estão associadas

OBJECTIVE: To evaluate the coexistence of psoriasis with metabolic syndrome-related comorbidities, and to identify the association of this dermatosis features (severity, clinical presentation and type of treatment) with these comorbidities. METHODS: This is a hospital based, cross-sectional and descriptive study involving individuals with psoriasis attended in a reference outpatient clinic, from 2014 to 2015, with no selection restrictions. Data were obtained through a questionnaire, clinical evaluation and laboratory tests; data analysis was first descriptive and, subsequently, by univariate logistic regression. RESULTS: Fifty-nine subjects were included. Among these, 55.9% had abdominal obesity, 72.9% had arterial hypertension, and 62.7% had decrease in HDL cholesterol. The presence of more severe psoriasis (Psoriasis Area Severity Index - PASI>10) indicated increased odds for the occurrence of arterial hypertension, high blood glucose and triglycerides levels; patients with clinical presentations other than psoriasis vulgaris had increased odds to all comorbidities, except for high triglycerides levels, and patients using systemic medications had increased odds to abdominal obesity, high blood glucose and triglycerides levels. CONCLUSIONS: There was coexistence of psoriasis with metabolic syndrome-related comorbidities. There is possible association of clinical presentations other than psoriasis vulgaris, severe psoriasis and systemic treatment with these comorbidities.

Enxerto por raspagem epidérmica no vitiligo estável: uma opção terapêutica / Grafting by epidermal scraping in stable vitiligo: a therapeutic option

O vitiligo é despigmentação adquirida caracterizada pela perda parcial ou total dos melanócitos da epiderme. Inúmeras modalidades terapêuticas foram propostas para seu tratamento. Nos casos de vitiligo estável os tratamentos cirúrgicos são a preferência. O enxerto por raspagem epidérmica é uma variante da técnica de microenxertos por punch. Constitui técnica nova, simples e de baixo custo, com altas taxas de repigmentação. O objetivo deste relato é demonstrar a experiência dos autores com essa técnica e discutir os resultados obtidos numa série inicial de dois casos (três lesões).

Vitiligo is an acquired depigmentation characterized by partial or total loss of epidermal melanocytes. Many therapeutic modalities have been proposed for its treatment. In cases of stable vitiligo surgical treatments are preferred. Grafting by epidermal scraping is a variant of micrografts by punch technique. It is a new, simple and low cost technique, with high rates of repigmentation. The objective of this report is to demonstrate the authors' experience with this technique and discuss the results in an initial series of two cases (three lesions).

Porokeratosis of Mibelli - literature review and a case report / Poroqueratose de Mibelli - revisao da literatura e relato de um caso

Porokeratosis is a disorder of epidermal keratinization characterized by annular plaques with an atrophic center and hyperkeratotic edges, and includes a heterogeneous group of disorders that are mostly inherited in an autosomal dominant form. This report describes a 5 year-old female patient, with porokeratosis of Mibelli confirmed histopathologically. The rarity of this disorder, its clinical exuberance and the destructive character of the lesions, as well as the facial and mucosal involvements, unusual in this form of porokeratosis, and also its onset in early childhood motivated this report.

A poroqueratose é uma desordem da queratinização epidérmica caracterizada por placas anulares com centro atrófico e bordas hiperqueratóticas, e inclui um grupo heterogêneo de desordens que são na sua maioria herdadas de forma autossômica dominante. O presente caso refere-se a uma paciente feminina de 5 anos de idade, com poroqueratose de Mibelli confirmada histologicamente. A raridade desta desordem, a exuberância clínica e o caráter destrutivo das lesões, o acometimento facial e mucoso pouco usuais nesta forma de poroqueratose e o início na infância precoce motivaram este relato.

Acral pseudolymphomatous angiokeratoma: case report and literature review / Angioqueratoma pseudolinfomatoso acral: relato de caso e revisao da literatura

The authors describe a case of a female patient with Acral Pseudolymphomatous Angiokeratoma of Children, known as APACHE. It is a rare benign cutaneous disease, of unknown etiology, characterized by multiple, asymptomatic erythematous-violaceous papules and nodules, usually located unilaterally with acral distribution. Today, this denomination is questionable, since there are published reports of this disease in adults and in different locations. Clinically, it is similar to an angiokeratoma, whereas hystologically, it corresponds to a distinct type of pseudolymphoma. The immunohistochemical study is required to distinguish APACHE from cutaneous lymphoma.

Relata-se o caso de uma paciente com diagnóstico de angioqueratoma pseudolinfomatoso acral, conhecido por sua sigla em inglês APACHE - Acral Pseudolymphomatous Angiokeratoma of Children. É uma doença cutânea benigna, rara, de etiologia desconhecida, caracterizada por múltiplas pápulas e nódulos eritêmato-violáceos assintomáticos, de localização geralmente unilateral e acral. Atualmente, questiona-se esta denominação, já que há relatos na literatura do quadro em adultos e em outras localizações. Clinicamente, é similar a um angioqueratoma, porém, histologicamente, corresponde a um tipo distinto de pseudolinfoma. O estudo imuno-histoquímico é necessário para diferenciação dos linfomas cutâneos.

Differences in age and topographic distribution of the different histological subtypes of basal cell carcinoma, Taubaté (SP), Brazil / Diferencas na idade e distribuicao topografica dos diferentes subtipos histologicos de carcinoma basocelular, Taubate (SP), Brasil

BACKGROUND: Basal cell carcinoma is the most common form of cancer in humans. OBJECTIVES: To identify the epidemiology of basal cell carcinoma in Taubaté-SP and verify a possible association between topography and the different histological subtypes of this tumor. METHODS: This was a cross-sectional study conducted at The University Hospital of Taubaté between 01/01/08 and 12/31/09. The study included patients with a confirmed diagnosis of basal cell carcinoma, of both genders, without age restrictions. The variables studied were incidence of basal cell carcinoma, topography, histological subtype, skin color, age and gender. We employed the chi-square test to identify the association between histological subtype and topography, and the student's t test to compare the mean age of onset for the different histological subtypes. RESULTS: The study included 239 individuals. The mean age of the sample was 68.0 years. Male subjects (57.7%) and whites (87.1%) predominated in the study. The predominant histological subtype was nodular (34.7%), followed by the superficial subtype. The most frequent sites of involvement were the head and neck (areas exposed to light), with predominance of the nasal region. The superficial subtype was an exception, as it showed a strong association with unexposed areas like the trunk. The mean age of onset of superficial basal cell carcinoma also differed from that of the other histological subtypes, 63.0 and 69.0 years, respectively. CONCLUSION: The results of this study suggest an association of the superficial histological subtype with younger patients and unexposed areas of the body, linking this type of tumor with a pattern of intermittent sun exposure, more similar to the standard photocarcinogenesis of melanoma. .
