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.

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.

Mortality due to cutaneous melanoma in south region of Brazil: a spatial approach.

BACKGROUND: Cutaneous melanoma is a skin cancer with low incidence but high mortality rates. The South region of Brazil has the highest death rates by melanoma per 100,000 inhabitants of the country. Little is known about the spatial distribution of this malignancy in southern Brazil. OBJECTIVES: Identify the spatial patterns of deaths from cutaneous melanoma in South region of Brazil, using geoprocessing tools. METHODS: This is an ecological and exploratory study of death information by cutaneous melanoma obtained from portal Datasus, for Brazil's southern region, from January 2008 to December 2012. Deaths were separated by gender and rates per 100,000 inhabitants were calculated and used to compile thematic maps, Moran maps and Kernel maps, using TerraView software. It was adopted an alpha = 5%. RESULTS: There were data on 2378 deaths from cutaneous melanoma in the study period. High rates were identified in the northern and littoral regions of Rio Grande do Sul; the northeast of Santa Catarina; and west of Paraná - for the total population, with minor differences detected and indicated regarding gender. The global Moran index presented p-values of 0.03, 0.04 and 0.03, respectively, for male, female and overall deaths. All the micro-regions that showed high priority for intervention were detected in the Rio Grande do Sul. CONCLUSION: Spatial clusters of micro-regions with high death rates from cutaneous melanoma in South region of Brazil were identified, serving as an important tool for health managers.
