The relation between atopic dermatitis and depressive symptoms / A relação entre dermatite atópica e sintomas depressivos

Introdução: O quadro da dermatite atópica (DA) é caracterizado por prurido crônico de evolução flutuante, que pode resultar em distúrbios no padrão de sono e em estigmatização social devido à presença de lesões visíveis e recidivantes, as quais tendem a se tornar progressivamente liquenificadas. Fatores como os já citados e outros associados, como incapacidade laboral, falta de concentração ao longo do dia e isolamento apresentam-se como profundos impactantes para a saúde mental do paciente, podendo resultar em baixa autoestima, depressão e frustração. Além disso, sabe-se que a DA é uma doença essencialmente inflamatória, ao mesmo tempo em que estudos recentes demonstram papel de citocinas no desenvolvimento de síndromes depressivas, podendo haver correlação causal entre os quadros por vias inflamatórias. Objetivos: Essa revisão sistemática de literatura objetivou analisar a relação entre dermatite atópica e sintomas depressivos, identificando possíveis mecanismos responsáveis por essa ligação. Métodos: A busca foi feita entre 17/11/2020 e 18/11/2020 seguindo o modelo PRISMA e utilizando as bases PUBMED, Biblioteca Virtual em Saúde (BVS) - IBECS, LILACS e CUMED - e EMBASE. As palavras-chave "Depression" e "Atopic Eczema", em conjunto com seus termos MeSh e DECS, foram utilizadas e associadas através do método booleano. Critérios para inclusão foram definidos como artigos que são ensaios clínicos ou observacionais envolvendo grupo de pacientes com dermatite atópica e grupo controle, que pôde ser constituído pelo próprio grupo com dermatite atópica, porém, após intervenção. Os sintomas depressivos precisavam ser medidos por escalas ou terem critérios para diagnóstico de síndrome depressiva estabelecidos. A seleção foi feita por todos os autores de forma independente, sendo discordâncias solucionadas por consenso. Resultados: Ao final, quinze estudos restaram, os quais foram classificados entre aqueles que comparam tratamentos e seus desfechos relacionados à depressão e DA, aqueles que propõem DA como agravante de sintomas depressivos, aqueles que propõem sintomas depressivos como agravantes da DA e aqueles que trazem análises estatísticas sem estabelecer claramente onde reside a relação de causalidade entre os dois quadros. Conclusões: Diversos estudos mostraram a existência de relação entre o quadro de DA e sintomas depressivos em vias distintas, tanto analisando a DA como agravante de sintomas depressivos como vice-versa. A partir dessa perspectiva, é possível que haja uma causalidade bidirecional cíclica, na qual um constante feedback positivo gera piora de ambos os quadros até que a abordagem adequada seja tomada, evidenciando a importância da propedêutica multidisciplinar para esses pacientes (AU)

Introduction: Atopic dermatitis (AD) is characterized by chronic itching, presenting with fluctuating evolution, resulting in sleep disorders and social stigmatization due to the presence of visible and recurrent lesions, that might become progressively lichenified. Factors such as those mentioned and others associated, such as incapacity for work, lack of concentration throughout the day and isolation have profound impacts on the patient's mental health, resulting in low self-esteem, depression and frustration. In addition, it is known that AD is essentially an inflammatory disease. And, recent studies demonstrate the role of inflammatory cytokines in the development of depressive syndromes, therefore may be a causal correlation between the conditions by inflammatory pathways. Objectives: This systematic literature review aimed to analyze a relationship between atopic dermatitis and depressive symptoms, identifying mechanisms responsible for this connection. Methods: The research was carried out between 11/17/2020 and 11/18/2020 following the PRISMA model and using PUBMED, Virtual Health Library (VHL) - IBECS, LILACS and CUMED - and EMBASE databases. Keywords "Depression" and "Atopic Eczema", along with its MeSh and DECS terms, were used and associated using the Boolean method. Inclusion criteria were defined as articles that are clinical or observational trials involving a group of patients with atopic dermatitis and a control group, which could be constituted by the group with atopic dermatitis itself, however, after an intervention. The depressive symptoms had to be measured by scales or, at least, the criteria for diagnosis of depressed syndrome must have been established. Results:In the end, fifteen studies remained, which were classified among those that compare treatments and their outcomes related to depression and AD, those that propose AD as an aggravator of depressive symptoms, those that propose depressive symptoms as an aggravating factor for AD and those that bring statistical analysis without clearly establishing where the causality relation resides. Conclusion: Several studies have presented a relationship between the condition of AD and depressive symptoms in distinct pathways, or analyzing AD as an aggravating factor for depressive symptoms or vice-versa. From this perspective, there may be a cyclical bidirectional causality, in which constant positive feedback generates worsening of both conditions until the adequate approach is taken, highlighting the importance of the multidisciplinary propaedeutics for these patients (AU)

Síndrome de hiperinmunoglobulinemia E: dermatitis atópica como manifestación inicial. A propósito de un caso / Hyper IgE syndrome: atopic dermatitis as first manifestation. Case report

La dermatitis atópica es la forma más frecuente de eccema durante el primer año de vida; sin embargo, cuando la presentación es atípica o se asocia a infecciones, constituye un desafío diagnóstico para el pediatra. Es importante mantener un índice alto de sospecha para detectar inmunodeficiencias primarias asociadas a eccemas graves desde el período neonatal. Un ejemplo de estas es el síndrome de hiperinmunoglobulinemia E (hiper-IgE) autosómico dominante. Este cuadro se caracteriza por la presencia de infecciones cutáneas y respiratorias recurrentes, dermatitis atópica, eosinofilia y aumento de IgE. Se reporta el caso clínico de una niña de 1 mes y 29 días con diagnóstico de hiper-IgE con afección cutánea desde el nacimiento.

Atopic dermatitis is the most common form of eczema often developed before the first year of life. Nevertheless, when the presentation is atypical or related to infections the diagnostic represents a challenge for the pediatricians. It is important to maintain a high index of suspicion for the detection of primary immunodeficiency associated to severe eczema. One of them is the autosomal dominant hyper-IgE syndrome characterized by recurrent skin and respiratory infections, atopic dermatitis, eosinophilia, and high serum IgE concentrations. In this paper, we report a 1 months and 29 days old baby girl diagnosed with hyper-IgE and a skin involvement since birth.

Prevalencia de asma, rinitis, dermatitis atópica en escolares, San Pedro Sula, Honduras, 2020 / Prevalence of asthma, rhinitis, atopic dermatitis in schoolchildren, San Pedro Sula, Honduras, 2020

La prevalencia de las enfermedades atópicas va en aumento de manera impor- tante, especialmente en la población infantil a nivel mundial según la Organización Mundial de la Salud. Dentro de estas enfermedades están incluidas el asma, rinitis y la dermatitis atópica. Objetivo: Determinar la prevalencia de asma, rinitis y dermatitis atópica en escolares de 6 a 12 años en San Pedro Sula, Honduras en el año 2000. Pacientes y Métodos: Estudio descrip- tivo, cuantitativo, no experimental. La muestra fue de 1500 escolares matriculados en diversas escuelas que fueron seleccionadas por un método no probabilístico por conveniencia. La reco- lección de datos se realizó mediante la aplicación de un instrumento tipo encuesta a escolares que cumplían con los criterios de inclusión y contaban con consentimiento informado. Los datos se tabularon en SPSS. Resultados: La prevalencia de asma fue 24.46% (367), rinitis 17% (255) y dermatitis atópica 11.69% (175). Se encontró que 15.73% (236) tenían asma y rinitis; 9.53% (143) asma y dermatitis; y 8.40% (126) padecían rinitis y dermatitis. Además, 7.93% (119) padecían de las tres enfermedades. Conclusión: Los datos de prevalencia de asma y de dermatitis atópica en Escolares de San Pedro Sula son mayores a los encontrados en estudios de prevalencia de dichas enfermedades en Latinoamérica. Sin embargo, la preva- lencia de rinitis en San Pedro Sula es menor en comparación a la señalada en estos estudios...(AU)

Pediatric dermatoses pattern at a Brazilian reference center

Abstract Objective: The aim of this study was to identify the pattern of pediatric dermatoses of patients evaluated at a dermatologic clinic of a reference center in Brazil and to compare these results to similar surveys conducted in other countries. Methods: A retrospective study was performed of patients up to 18 years old, evaluated at a dermatologic clinic between January 1, 2017 and December 31, 2017. Variables collected for analysis included age, gender, dermatological diagnosis, multidisciplinary follow-up, hospitalization, and complementary exams. Results: A total of 2330 patients were included for analysis, with a mean age of 9.7 years. 295 patients were diagnosed with more than one skin disease, leading to a total of 2668 diagnoses. Skin diseases were organized into categories and inflammatory dermatoses corresponded to the largest group (31.2%), mostly due to atopic dermatitis (18.3%). The other main categories were: genodermatoses (14.2%), infectious diseases (12.6%), adnexal disorders (12.5%), cysts and neoplasms (10.7%), and vascular disorders (7.0%). Fifty-six patients needed to be admitted to the dermatology ward; 25 of them (44.6%) for management of worsening of the skin disease, mainly atopic dermatitis, psoriasis, and drug reactions. There were 885 biopsies performed in 38.0% of the subjects and 751 patients (32.2%) required multidisciplinary care; most of them had some genodermatoses. Conclusions: Dermatologic disorders are very common in the pediatric age group and differ from those in adults, suffering influence from cultural, ethnic, socioeconomic, and environmental factors. Knowing the magnitude and distribution of these dermatoses is important to better plan healthcare policies.

Prevalence of canine atopic dermatitis at the Veterinary Hospital of the "Universidade Federal Rural da Amazônia" in Belém/Pará, Brazil / Prevalência de dermatite atópica canina no Hospital Veterinário da Universidade Federal Rural da Amazônia em Belém/Pará, Brasil

Canine atopic dermatitis (CAD) is a pruritic, chronic inflammatory disease, recurrent and genetically predisposed, which is the second most frequent allergic skin disorder, and ranks second among all the causes of pruritus in dogs worldwide. Given the absence of data on the occurrence of CAD in the northern region of Brazil, the aim of the current study was to conduct a survey to define the prevalence of canine atopic dermatitis attended at the Dermatology Department of the Mário Dias Teixeira Veterinary Hospital of the "Universidade Federal Rural da Amazônia" (HOVET-UFRA). To determine the prevalence of CAD, a retrospective survey was carried out of clinical records and results of dermatological examinations conducted at the Dermatology Department of HOVET-UFRA Belém, Pará from October 2018 to October 2019. During this period, 456 dogs were examined, of which 25.65% (117) were diagnosed with atopic dermatitis. Among the animals diagnosed, 62.4% (73) were females and 51.7% (29) were of the Shih-tzu breed. This level of atopic dermatitis is considered high. There are still no exact data on the incidence and prevalence of this dermatopathy, with described occurrence ranging from 3 to 15% of the canine population, a geographical relationship may be present. Although a sex-related predisposition has not been proven, a higher incidence of atopy in females is described, which indicated this may be the case. The most commonly diagnosed dogs in this study were the Shih-tzu breed. It is suspected that the regional popularity of some breeds, or the different genetic backgrounds in different geographical areas, may affect the predominance of CAD in some breeds. The results of the present study demonstrate the need for more research on the prevalence of canine atopic dermatitis, and better means of characterizing the population of atopic dogs in the region, so that it is possible to obtain a reliable epidemiological profile.(AU)

A dermatite atópica canina (DAC) é uma doença inflamatória crônica e pruriginosa recorrente e geneticamente predisposta, que se destaca como o segundo transtorno cutâneo alérgico mais frequente e ocupa o segundo lugar entre todas as causas de prurido em cães. Diante da ausência de dados da ocorrência de DAC na região Norte do Brasil, objetivou-se realizar um levantamento de dados para definir a prevalência de dermatite atópica canina atendida no Serviço de Dermatologia do Hospital Veterinário Mário Dias Teixeira da Universidade Federal Rural da Amazônia (HOVET-UFRA). Foi realizado um levantamento retrospectivo através dos registros clínicos e dos resultados de exames dermatológicos com base nos atendimentos dermatológicos no setor de Dermatologia do HOVET-UFRA Belém/Pará, de outubro de 2018 a outubro de 2019 para determinar a prevalência de DAC. Nesse período, foram atendidos 456 cães e destes, 25,65% (117) foram diagnosticados com dermatite atópica. Dentre os animais diagnosticados, 62,4% (73) eram fêmeas e 51,7% (29) eram da raça Shih-tzu. Neste estudo houve uma alta prevalência de cães com Dermatite atópica. Ainda não existem dados exatos sobre a incidência e a prevalência desta dermatopatia, com ocorrência descrita variando de 3 a 15% da população canina, podendo ter relação geográfica. Embora a predisposição sexual não tenha sido comprovada, descreve-se maior incidência de atopia em fêmeas, concordando com esta pesquisa. Os cães mais acometidos neste estudo foram da raça Shih-tzu. Suspeita-se que a popularidade regional de algumas raças ou os diferentes antecedentes genéticos em diferentes áreas geográficas afetam a predominância de algumas raças. Estes resultados mostraram que a prevalência de DAC em cães é a mais frequentemente diagnosticada no setor de Dermatologia do HOVET-UFRA, sendo mais prevalente em fêmeas e na raça Shih-tzu, podendo refletir um aspecto regional desta dermatopatia. Os resultados do presente estudo contribuíram para demonstrar a importância de mais pesquisas sobre a prevalência da Dermatite atópica canina e melhor caracterizar a população de cães atópicos na região, para que seja possível obter um perfil epidemiológico confiável.(AU)

Análise da ocorrência dos critérios de Favrot e das comorbidades apresentadas por cães com dermatite atópica atendidos no Hospital Veterinário da Universidade Federal Fluminense / Analysis of the occurrence of Favrot's criteria and comorbidities presented by dogs with atopic dermatitis treated at the Veterinary Hospital of Universidade Federal Fluminense

O objetivo desse trabalho foi analisar a ocorrência dos critérios de Favrot em cães diagnosticados com Dermatite Atópica Canina (DAC) no Hospital Veterinário Professor Firmino Mársico Filho da Universidade Federal Fluminense, bem como sua associação com doenças concomitantes. Foram analisadas 2199 fichas propedêuticas com queixas dermatológicas, dos anos de 2016 e 2017. Do total, 165 (7,5%) animais foram diagnosticados com DACdos quais 94 (57%) eram fêmeas e 71 (43%) machos. Embora os cães mestiços fossem a maioria dos casos (22,4%), a raça pura mais frequentemente acometida foi a Poodle (12,5%). Foram identificados 134 (81,2%) cães com cinco ou mais critérios de Favrot, sendo 32,7% animais com seis critérios, 26,7% com cinco critérios, 17,0% com sete critérios e 4,8% com oito critérios. Enfatiza-se o aparecimento em mais de 90% dos casos os critérios intradomiciliado, com prurido primário, responsivo à corticoterapia e com bordas das pinas não acometidas. Dos 165 animais avaliados, 115 (69,7%) eram portadores de uma ou mais afecções concomitantes à DAC, sendo a otite externa a principal (73%). Considera-se que os critérios de Favrot podem ser aplicados para a triagem dos pacientes com suspeita de dermatite atópica canina atendidos no HUVET-UFF.

The objective of this study was to analyze the occurrence of Favrot criteria in dogs diagnosed with Canine Atopic Dermatitis (CAD) at the Veterinary Hospital Professor Firmino Mársico Filho of Universidade Federal Fluminense, as well as its association with concomitant diseases. A total of 2199 propaedeutic records with dermatological complaints from 2016 and 2017 were analyzed. Of the total, 165 (7.5%) animals were diagnosed with CAD. Among those diagnosed with CAD, 94 (57%) were females and 71 (43%) males. Although crossbreed dogs were the majority of cases (22.4%), the purebred dog most frequently affected by CAD was the Poodle (12.5%). One hundred and thirty four (81.2%) animals were identified with five or more Favrot criteria, 32.7% animals with six criteria, 26.7% with five criteria, 17.0% with seven criteria and 4.8% with eight criteria. It emphasizes the appearance in more than 90% of criteria, dog living mostly indoors,alesional pruritus, glucocorticoid-responsive pruritus and nonaffected ear margins. Of the 165 animals evaluated, 115 (69.7%) had one or more conditions concomitant with CAD, with otitis externa being the main one (73%). It is considered that the Favrot criteria can be applied for the screening of patients with suspected canine atopic dermatitis treated at HUVET-UFF.

Correlation of nipple eczema in pregnancy with atopic dermatitis in Northern India: a study of 100 cases

Abstract Background Nipple eczema is a less common presentation of atopic dermatitis. No studies in the literature have correlated nipple eczema in pregnancy as a manifestation of atopic dermatitis. Objective To evaluate whether nipple eczema presenting in pregnancy is a manifestation of atopic dermatitis. Methods This was a prospective observational study including 100 women who presented with nipple eczema for the first time during pregnancy. The exclusion criteria were any patient with previous history of nipple eczema, those already on oral or topical treatment for atopic dermatitis or nipple eczema, and other disorders mimicking eczema. Patients were divided into two groups ‒ nipple eczema with atopic dermatitis and without atopic dermatitis. Demographic data, clinical features, total leukocyte count, differential leukocyte count, absolute eosinophil counts, and serum IgE levels were compared between the two groups to detect association between nipple eczema in pregnancy and atopic dermatitis. Results Out of 100 patients, 39 were diagnosed with atopic dermatitis, whereas 61 were ruled out to have any features suggestive of atopic dermatitis. There were no statistically significant differences in mean age, mean duration of symptoms, and serum IgE levels. In patients with atopic dermatitis, bilateral symptoms were noted more commonly than in patients without the disease, but this was statistically insignificant. Study limitations Lack of long term follow-up and no large studies in literature to compare results. Conclusion Nipple eczema in pregnancy follows a similar pattern as in other age groups. The clinical profile of patients is similar in cases with and without atopic dermatitis.

The results that are offered in this work will contribute to the professional formation for a better promotion, prevention, precocious diagnosis and treatment of this illness that is more likely to be found in the childhood.

Dermatitis atópica del adulto: un desafío diagnóstico y terapéutico / Adult atopic dermatitis: a challenge diagnosis and therapy

Adult atopic dermatitis is a chronically recurring inflammatory dermatosis which presents in various forms. Some of these forms develop mostly in adults such as head and neck dermatitis and chronic hand eczema. Even though the diagnosis is clinical it frequently requires further investigations to exclude differential diagnosis. Once confirmed, it is crucial to classify its severity and exclude other comorbidities. Treatment includes general measures such as the use of emollients and soap substitutes which are applicable in all cases regardless of its severity. Other therapeutic options include topical corticosteroids, topical calcineurin inhibitors, phototherapy and immunosuppressants. Their use will depend on the degree of severity and specific characteristics of each individual. Newer biologics have proven to be a safe and effective alternative, and seem to be a promising option in cases of adult atopic dermatitis refractory to conventional treatments. (AU)

La Histiocitosis de Células de Langerhans (HCL) es una neoplasia mieloide de las células dendríticas Langerhans (CDL), caracterizada por acúmulos de células dendríticas mieloides CD207+. Corresponden a un espectro de enfermedades, desde sólo cutáneas a variantes multiorgánicas. El objetivo de este reporte es describir el caso clínico de un paciente pediátrico, con diagnóstico de Histiocitosis de Células de Langerhans, enfatizando el algoritmo clínico. Paciente masculino de 1 año y 5 meses, con antecedentes de otorrea persistente, refractaria a tratamiento, de un año de evolución. Consulta en policlínico de dermatología por "dermatitis severa" desde hace 1 año. Al examen físico se constatan lesiones tipo dermatitis seborreica generalizadas en tronco y cuero cabelludo, intertrigo fisurado, pápulas eritemato-costrosas plantares con petequias y pus en conducto auditivo externo bilateral. Presenta Hemoglobina 9,5 mg/dl, Hematocrito31,9%, leucocitos 12.400, linfocitos 33,3%, plaquetas 920.000, VHS 27. Subpoblaciones linfocitarias: CD3: 34,7%, C4: 22,7%, CD8: 9,7%, CD19:47,8%. HTLV negativo, VIH negativo. Acaro-test negativo. Dermatopatología: Denso infiltrado de células linfomonocíticas en dermis papilar, con ensanchamiento de estas y gran epidermotropismo, con abundante citoplasma eosinófilo con núcleos arriñonados, CD1a y langerina positivo. Recomendamos elevar la sospecha diagnóstica ante un cuadro de dermatitis seborreica generalizada que esta fuera del rango etario característico y en casos de dermatitis refractarias, donde a pesar de un adecuado tratamiento médico, el paciente persiste comprometido.

Langerhans Cell Histiocytosis (HCL) is a myeloid neoplasm of Langerhans dendritic cells (CDL), characterized by accumulations of myeloid dendritic cells CD207 +. They correspond to a spectrum of diseases, from cutaneous to multi-organ variants. The objective of this report is to describe the clinical case of a pediatric patient with diagnosis of, emphasizing the clinical algorithm. Male patient,1 year and 5 months old, with a history of refractory persistent otorrhea, consulted because of long term severe dermatitis. Physical examination revealed generalized seborrheic dermatitis lesions on the trunk and scalp, cleft intertrigo, plantar erythematous-crusted papules with petechiae, and pus in the external auditory canal. Laboratory findings showed: Hemoglobin 9.5 mg / dl, Hematocrit: 31.9%, leukocytes: 12,400, lymphocytes 33.3%, platelets: 920,000, HSV 27. Lymphocyte subpopulations: CD3: 34.7%, C4: 22.7%, CD8: 9.7%, CD19: 47.8%. HTLV negative, HIV negative. Scabies Negative. Dermatopathology: Dense infiltrate of lymphomonocytic cells in the papillary dermis with widening of the papilla and large epidermotropism, cells show abundant eosinophilic cytoplasm with "kidney nuclei", CD1a and langerin were positive. We recommend elevating the diagnostic suspicion in the face of a generalized seborrheic dermatitis that is outside the characteristic age range and in cases of refractory dermatitis, where the patient persists compromised.

Case for diagnosis. Infective dermatitis associated with HTLV-1: differential diagnosis of atopic dermatitis

Abstract: Infective dermatitis associated with HTLV-1 (IDH) is the main cutaneous marker of HTLV-1 infection. This disease occurs primarily in children and should be differentiated from other eczemas, especially from atopic dermatitis. The largest series of IDH are from Jamaica and Brazil. There are an estimated 15 to 20 million infected people in the world, and Brazil is one of the endemic regions. Studies suggest that IDH in children may be a marker for the development of T-cell leukemia/lymphoma (ATL) or myelopathy associated with HTLV-1/tropical spastic paraparesis (HAM / TSP) in adulthood.

Guia prático de atualização em dermatite atópica - Parte I: etiopatogenia, clínica e diagnóstico. Posicionamento conjunto da Associação Brasileira de Alergia e Imunologia e da Sociedade Brasileira de Pediatria / Updated practical guide on atopic dermatitis - Part I: etiopathogenesis, clinical features, and diagnosis. Joint position paper of the Brazilian Association of Allergy and Immunology and the Brazilian Society of Pediatrics

A dermatite atópica (DA) é uma doença crônica e recidivante que acomete principalmente pacientes da faixa etária pediátrica. A fisiopatologia inclui fatores genéticos, alterações na barreira cutânea e imunológicas. A prevalência da DA no Brasil, entre adolescentes, oscila entre 7,1% e 12,5%, com tendência à estabilização. O diagnóstico é clínico, e exames complementares auxiliam na determinação dos fatores desencadeantes. A identificação dos fatores irritantes e/ou desencadeantes envolvidos permite melhor controle das crises. Entre os fatores desencadeantes destacam-se os agentes infecciosos, alérgenos alimentares e aeroalérgenos. Tomando-se como ponto de partida o "Guia Prático para o Manejo da Dermatite Atópica ­ opinião conjunta de especialistas em alergologia da Associação Brasileira de Alergia e Imunopatologia e da Sociedade Brasileira de Pediatria" publicado em 2006, foi realizada revisão e atualização dos conceitos apresentados por grupo de alergologistas, dermatologistas e pediatras especializados no tratamento de pacientes com DA. O objetivo desta revisão foi elaborar um documento prático e que auxilie na compreensão dos mecanismos envolvidos na DA, assim como dos possíveis fatores de risco associados a sua apresentação, bem como sobre a avaliação subsidiária disponível para a identificação dos fatores associados à DA.

Atopic dermatitis (AD) is a chronic, recurrent skin disease that mainly affects pediatric patients. The pathophysiology of AD includes genetic factors, skin barrier abnormalities, and immunological factors. The prevalence of AD in Brazil, among adolescents, ranges from 7.1% to 12.5%, with a trend towards stabilization. The diagnosis of AD is clinical, and complementary tests can help determine the triggering factors. Identification of the irritating and/or triggering factors involved allows better control of exacerbations. Among the triggering factors, infectious agents, food allergens, and aeroallergens stand out. Taking as a starting point the Practical Guide for the Management of Atopic Dermatitis ­ joint opinion of specialists in allergology of the Brazilian Association of Allergy and Immunopathology and of the Brazilian Society of Pediatrics, published in 2006, the present paper describes the results of the review and update of different concepts related to AD, conducted by a group of allergists, dermatologists, and pediatricians specializing in the treatment of patients with AD. The objective of this review was to design a practical document that can help improve our understanding of the mechanisms involved in AD, possible risk factors associated with its presentation, as well as ancillary tests available to identify factors associated with AD.

Caracterización de la Dermatitis ocupacional en pacientes evaluados en consulta de Dermatología / Characterization of the occupational Dermatitis in patients evaluated in consultation of Dermatology

Introducción: La Dermatitis ocupacional es una inflamación de la piel provocada por el entorno laboral o contacto de una sustancia perjudicial, siendo considerada el problema de salud más frecuente en el ámbito laboral. Objetivo: Describir las características de los pacientes con Dermatitis ocupacional atendidos en una consulta de Dermatología durante 2015.

IMPACTO DA DERMATITE ATÓPICA NA QUALIDADE DE VIDA DE PACIENTES PEDIÁTRICOS E SEUS RESPONSÁVEIS / IMPACT OF ATOPIC DERMATITIS ON THE QUALITY OF LIFE OF PEDIATRIC PATIENTS AND THEIR GUARDIANS

RESUMO Objetivo: Avaliar o impacto da dermatite atópica na qualidade de vida de pacientes pediátricos de 5 a 16 anos e seus responsáveis, atendidos no serviço de dermatologia da Universidade do Estado do Pará (UEPA) em 2015. Métodos: Estudo transversal de 51 pacientes juntamente com seus responsáveis, aos quais foram aplicados dois questionários de qualidade de vida, o Escore da Qualidade de Vida na Dermatologia Infantil (CDLQI) e o Impacto da Dermatite Atópica na Família (DFI). Para avaliar a gravidade da doença, os pesquisadores aplicaram o índice de Severity Scoring of Atopic Dermatitis (SCORAD). A correlação linear de Pearson foi aplicada para averiguar a correspondência entre os instrumentos CDLQI, DFI e SCORAD, e o coeficiente de contingência C para avaliar a associação entre as variáveis qualitativas. Considerou-se significante p<0,05. Resultados: Dos pacientes, 55% pertenciam ao sexo feminino. A idade média foi de 9.5±3.2 anos, e 41% tinha renda familiar de até um salário-mínimo. A média dos escores foi de 5.4±5.1 para o CDLQI, 6.6±4.5 para o DFI e 28.3±19.8 para o SCORAD. Atestou-se correlação altamente significante entre os escores CDLQI, DFI e SCORAD pela correlação linear de Pearson (p<0.001). Conclusões: A dermatite atópica afeta a qualidade de vida tanto das crianças quanto de seus responsáveis, o que indica a importância de inserir o estudo da qualidade de vida de forma complementar à avaliação clínica dos pacientes.

ABSTRACT Objective: To evaluate the impact of atopic dermatitis on the quality of life of pediatric patients in the age group of 5-16 years, and their parents, assisted at the Dermatology Department of Universidade do Estado do Pará in 2015. Methods: A cross-sectional study including 51 patients and their guardians, to whom two questionnaires about the quality of life were applied, the Children’s Dermatology Life Quality Index (CDLQI) and the Dermatitis Family Impact (DFI). To evaluate the severity of the disease, the researchers applied the Severity Scoring of Atopic Dermatitis (SCORAD) index. The Pearson Product-Moment Correlation Coefficient (PPMCC) evaluated the correlation between CDLQI, DFI, SCORAD, and the contingency coefficient C evaluated the association between the qualitative variables, considering p<0.05 significant. Results: Of the patients, 55% were female. The average age was 9.5±3.2 years, and 41% had family income up ≤1 minimum wage. The average score was 5.4±5.1 for CDLQI, 6.6±4.5 for DFI, and 28.3±19.8 for SCORAD. The correlation among the scores CDLQI, DFI, and SCORAD was significant by the PPMCC (p<0,001). Conclusions: Atopic dermatitis affects the quality of life of both children and their guardians, and indicates the importance of including the study of quality of life as a complement to clinical evaluation.

Particular characteristics of atopic eczema in tropical environments. The Tropical Environment Control for Chronic Eczema and Molecular Assessment (TECCEMA) cohort study

Abstract: Background: Atopic dermatitis is a prevalent health problem in the world. Allergic sensitization is an important risk factor, but the roles of other factors, inherent in tropic region, are unknown. Objective: A cohort study was designed in a tropical city to investigate molecular and environmental risk factors for eczema, considering as particular features perennial exposure to mites, poor living conditions and others tropical characteristics. Methods: 433 patients were included at baseline and biological samples were collected during 24 months of follow-up. Clinical information was collected using questionnaires (SCORAD, DLQI and a subjective scale) during each clinical assessment. Results: The prevalence of atopic eczema was 93%, with similar frequency between children and adults; parents history of eczema and polysensitization to mites, dogs, cats, cockroaches and birds, were risk factors for severe and persistent eczema and allergic comorbidities. Food sensitization was present in 16% of patients but food-induced allergies were scarce. Psychiatric, dental and ocular disorders were the most frequent non-allergic comorbidities. Study limitations: selection bias. Conclusion: We presented a tropical cohort of patients with eczema and we identified some risk factors for severe and persistent dermatitis. Some patterns of sensitization were associated with severe eczema and respiratory symptoms, and the natural history of "atopic march" is different to that described in some industrialized countries. The collection of biological samples will contribute to the understanding of the gene/environment interactions leading to allergy inception and evolution.

Patch-test results in children and adolescents: systematic review of a 15-year period

Abstract The number of studies on patch-test results in children and adolescents has gradually increased in recent years, thus stimulating reviews. This paper is a systematic review of a 15-year period devoted to studying the issue. Variations pertaining to the number and age groups of tested children and/or adolescents, the number of subjects with atopy/atopic dermatitis history, the quantity, type and concentrations of the tested substances, the test technique and type of data regarding clinical relevance, must all be considered in evaluating these studies, as they make it harder to formulate conclusions. The most common allergens in children were nickel, thimerosal, cobalt, fragrance, lanolin and neomycin. In adolescents, they were nickel, thimerosal, cobalt, fragrance, potassium dichromate, and Myroxylon pereirae. Knowledge of this matter aids health professionals in planning preventive programs aimed at improving children's quality of life and ensuring that their future prospects are not undermined.

Há lugar para o uso de probióticos na prevenção e no tratamento da dermatite atópica pediátrica? / Can probiotics play a role in the prevention and treatment of pediatric atopic dermatiti

A dermatite atópica (DA) é a doença dermatológica crônica mais frequente na infância e traz impacto negativo na qualidade de vida do paciente e de seus familiares. Os probióticos surgem como uma nova opção terapêutica, pela sua capacidade de modulação da reposta imunológica do hospedeiro, produzindo benefícios à saúde. Realizou-se uma busca nas plataformas de dados científicos PubMed, SciELO e Cochrane, apurando estudos nos idiomas português, inglês e espanhol. Baseado nos bancos de descritores DeCS e MeSH foram utilizadas as seguintes palavras/expressões: probiotics, probiotics and atopic dermatitis, atopic dermatitis and child e suas correspondentes nas demais línguas, sendo selecionados estudos entre 1993 e 2014. Considerando o papel dos probióticos na prevenção da DA, foram encontrados sete ensaios clínicos randomizados, sendo que quatro destes apresentaram desfecho positivo e os demais foram inconclusivos. Avaliando-se as possibilidades terapêuticas dos probióticos, cinco dos sete estudos analisados evidenciaram que a imunomodulação exercida pelas cepas probióticas tem melhor resposta à DA, além de menos efeito colateral que o obtido com o uso de corticoides e imunossupressores sistêmicos. O uso de probióticos na prevenção e no tratamento da DA mostrou-se seguro e eficaz, com descrição de efeitos colaterais em apenas um estudo. É possível que a suplementação com probióticos alcance seu lugar no manejo clínico da DA, podendo ser uma alternativa mais interessante e menos onerosa se comparada à terapia conservadora utilizada atualmente.

Atopic dermatitis (AD) is the most common chronic skin disease in childhood and it causes negative effect on patients? and their families? quality of life. The probiotics arise as a new therapeutic option for their ability to modulate the host?s immune response and produce benefits on their health. The authors searched on the scientific databases PubMed, SciELO and Cochrane, assessing studies in Portuguese, English and Spanish. Based on the descriptive databases of MeSH and DeCS, the following words/ phrases were used: probiotics, probiotics and atopic dermatitis, atopic dermatitis and child and their correspondents in other languages, studies were selected between 1993 and 2014. Considering the role of probiotics in the prevention of AD, seven randomized controlledtrials were found, four of those had a positive outcome and the others were inconclusive. Evaluating probiotics? therapeutic potential, five of the seven analyzed studies showed that the immunomodulation exerted by probiotic strains has a better answer for AD, as well as minor side effects than those obtained with the use of systemic corticosteroids and immunosuppressants. The use of probiotics in the prevention and treatment of AD proved to be safe and effective, being that side effects have been reported in only one study. It is possible that supplementation with probiotics can play a role in the clinical management of AD, being a more interesting and less expensive alternative compared to conservative therapy currently used
