Introdução: As doenças de pele apresentam alta prevalência em ambientes hospitalares. Pacientes hospitalizados com dermatoses associadas apresentam maior risco de mortalidade do que indivíduos sem doenças de pele, reforçando a importância do diagnóstico e tratamento precoces. Métodos: Foi realizada uma revisão sistemática em cinco bases de dados Medline, SciELO, LILACS, Web of Science e Scopus, utilizando as palavras- chave “Inpatients” AND “Dermatology”, abrangendo o período de 2010 a 2020. Em seguida, foi realizada uma revisão narrativa por meio dos autores 'seleção de referências relevantes sobre dermatologia hospitalar, incluindo artigos de revisão, livros e outras publicações. Resultados: Com base na estratégia de busca, foram encontradas 166 publicações, das quais 26 estudos foram elegíveis para inclusão no estudo. A partir desta revisão da literatura, analisamos as frequências de dermatoses em pacientes hospitalizados e os tipos de cuidados dermatológicos. As doenças dermatológicas constituem patologias importantes nos hospitais, sendo as erupções infecciosas e medicamentosas as dermatoses mais prevalentes. Conclusão: Este estudo demonstra que as doenças dermatológicas são altamente frequentes entre os pacientes hospitalizados. A maioria dos estudos corrobora a contribuição da dermatologia para a assistência hospitalar.

Introdução: A pandemia da Covid-19 impôs um grande desafio para as universidades ao redor do mundo, em meio a necessidade de distanciamento social causado pela disseminação do novo coronavírus (Sars-Cov-2). Frente a esta conjuntura, docentes e discentes foram instigados a buscar alterativas para continuidade das atividades universitárias, dentre as quais a adoção de Tecnologias de Informação e Comunicação, assim como, a ampliação do papel das atividades extracurriculares. Nessa perspectiva, este artigo teve como objetivo relatar a experiência da Liga Acadêmica de Dermatologia da Universidade Federal de Ciências da Saúde (Liaderm - UFCSPA) durante a pandemia da Covid-19, analisando a importância das atividades extracurriculares e da educação digital como ferramentas de Educação Médica. Relato de experiência: Durante o período de isolamento social e de suspensão de aulas, as atividades de ensino, pesquisa e extensão da Liaderm - UFCSPA precisaram ser readaptadas. Os encontros da liga, antes presenciais, passaram a ocorrer sob a forma de reuniões online em plataformas de videoconferência, como Zoom® e Google Meet®, nos quais eram organizadas aulas teóricas e discussão de casos clínicos. Aulas abertas à comunidade acadêmica também foram realizadas, como o webinar sobre Cirurgia Dermatológica, que teve participação de estudantes de medicina e outras áreas da saúde de todo o país. Além disso, em vista a manter o engajamento social dos membros, a Liaderm organizou um manual com orientações básicas acerca das lesões dermatológicas desencadeadas pelo uso de Equipamentos de Proteção Individual (EPIs), essenciais para a proteção dos profissionais de saúde envolvidos com o atendimento aos pacientes com Covid-19. Conclusões: Durante a pandemia, a maioria das atividades desenvolvidas pela Liaderm - UFCSPA pôde ser mantida mediante a adoção de Tecnologias de Informação e Comunicação, como as plataformas de videoconferência. Ademais, o alcance das atividades de ensino da liga foi expandido com a participação de acadêmicos de diferentes estados do país e do exterior. Nesse sentido, as adaptações provocadas pela pandemia podem repercutir a longo prazo, tanto nos modelos de ensino adotados pelas escolas médicas, quanto no reconhecimento das atividades extracurriculares como recursos educacionais estratégicos para a formação em Medicina.

Hailey-Hailey disease, or familial benign pemphigus, is a rare bullous genodermatosis that usually presents with flaccid blisters, erosions, and maceration limited to flexural areas, resulting in increased morbidity and reduced quality of life for affected patients. The authors report an unusual case of generalized Hailey-Hailey disease with erythroderma and fatal outcome.

BACKGROUND: Atopic dermatitis is a highly prevalent inflammatory and pruritic dermatosis with a multifactorial etiology, which includes skin barrier defects, immune dysfunction, and microbiome alterations. Atopic dermatitis is mediated by genetic, environmental, and psychological factors and requires therapeutic management that covers all the aspects of its complex pathogenesis. OBJECTIVES: The aim of this article is to present the experience, opinions, and recommendations of Brazilian dermatology experts regarding the therapeutic management of atopic dermatitis. METHODS: Eighteen experts from 10 university hospitals with experience in atopic dermatitis were appointed by the Brazilian Society of Dermatology to organize a consensus on the therapeutic management of atopic dermatitis. The 18 experts answered an online questionnaire with 14 questions related to the treatment of atopic dermatitis. Afterwards, they analyzed the recent international guidelines on atopic dermatitis of the American Academy of Dermatology, published in 2014, and of the European Academy of Dermatology and Venereology, published in 2018. Consensus was defined as approval by at least 70% of the panel. RESULTS/CONCLUSION: The experts stated that the therapeutic management of atopic dermatitis is based on skin hydration, topical anti-inflammatory agents, avoidance of triggering factors, and educational programs. Systemic therapy, based on immunosuppressive agents, is only indicated for severe refractory disease and after failure of topical therapy. Early detection and treatment of secondary bacterial and viral infections is mandatory, and hospitalization may be needed to control atopic dermatitis flares. Novel target-oriented drugs such as immunobiologicals are invaluable therapeutic agents for atopic dermatitis.

Patients with psychocutaneous disorders often refuse psychiatric intervention in their first consultations, leaving initial management to the dermatologist. The use of psychotropic agents in dermatological practice, represented by antidepressants, antipsychotics, anxiolytics, and mood stabilizers, should be indicated so that patients receive the most suitable treatment rapidly. It is important for dermatologists to be familiar with the most commonly used drugs for the best management of psychiatric symptoms associated with dermatoses, as well as to manage dermatologic symptoms triggered by psychiatric disorders.

Objective. To determine the prevalence of skin changes during pregnancy and to relate their occurrence to specific factors in a population of south Brazil. Methods. A cross-sectional analytical study was carried out with 1284 puerperal patients. A questionnaire about skin changes during pregnancy was developed and applied by the authors to all puerperal women admitted in a tertiary hospital in south Brazil. Results. The appearance of striae during pregnancy was reported by 633 women (49.5%) and had a statistically significant association with primiparity, presence of stretch marks before pregnancy, and gestational weight gain above 21 kg. Facial blemishes were reported by 33.9% (n=434) and were associated with a positive family history, multiparity, and the use of facial sunscreen (p<0.0001). The onset or worsening of acne was identified in 35.7% (n=456) and was statistically associated with primiparity and Fitzpatrick phototypes IV and V. Hair alterations were reported by 44.5% (n=569) and were associated with primiparity (p=0.029). Conclusion. Although most of the skin changes during pregnancy are considered “physiologic,” they can cause significant discomfort. Thus, it is important to know them and to understand which risk factors may be associated with such changes.

Background: Topical antimicrobial drugs are indicated for limited superficial pyodermitis treatment, although they are largely used as self-prescribed medication for a variety of inflammatory dermatoses, including atopic dermatitis. Monitoring bacterial susceptibility to these drugs is difficult, given the paucity of laboratory standardization. Objective: To evaluate the prevalence of Staphylococcus aureus topical antimicrobial drug resistance in atopic dermatitis patients. Methods: We conducted a cross-sectional study of children and adults diagnosed with atopic dermatitis and S. aureus colonization. We used miscellaneous literature reported breakpoints to define S. aureus resistance to mupirocin, fusidic acid, gentamicin, neomycin and bacitracin. Results: A total of 91 patients were included and 100 S. aureus isolates were analyzed. All strains were methicillin-susceptible S. aureus. We found a low prevalence of mupirocin and fusidic acid resistance (1.1% and 5.9%, respectively), but high levels of neomycin and bacitracin resistance (42.6% and 100%, respectively). Fusidic acid resistance was associated with more severe atopic dermatitis, demonstrated by higher EASI scores (median 17.8 vs 5.7, p=.009). Our results also corroborate the literature on the absence of cross-resistance between the aminoglycosides neomycin and gentamicin. Conclusions: Our data, in a southern Brazilian sample of AD patients, revealed a low prevalence of mupirocin and fusidic acid resistance of S. aureus atopic eczema colonizer strains. However, for neomycin and bacitracin, which are commonly used topical antimicrobial drugs in Brazil, high levels of resistance were identified. Further restrictions on the use of these antimicrobials seem necessary to keep resistance as low as possible.

BACKGROUND Many therapies involving varying degrees of complexity have been used to treat acne scars, but none is considered the gold standard treatment. OBJECTIVE A comparative evaluation of 88% phenol and 90% trichloroacetic acid (TCA) applied using the chemical reconstruction of skin scars (CROSS) technique. MATERIALS AND METHODS A nonrandomized, single-blinded self-controlled clinical trial was conducted among patients with ice pick-type and boxcar-type atrophic acne scars. Using 88% phenol on the left hemiface and 90% TCA on the right hemiface was adopted as the standard practice of the CROSS technique. The dermatological quality of life index (DLQI) questionnaire, acne scar grading scale Echelle d´Evaluation Clinique des Cicatrices d'Acne (ECCA), and evaluation of improvement were performed pretreatment and post-treatment. RESULTS Regarding ECCA, significant differences were found in pretreatment and post-treatment (p < .001). Regarding tolerance to pain, it was found that the discomfort felt with 90% TCA was significantly less than that felt with 88% phenol (p = .020). Regarding the quality of life measured with the DLQI, the results showed that the mean score in post-treatment assessment was significantly lower than that in the pretreatment assessment (p < .05). Hypochromia and enlargement scar were only seen after the use of 90% TCA. CONCLUSION This study confirmed the efficacy of both TCA and phenol for treating such scars, with less severe complications from the use of phenol.

Today, obesity is considered an epidemic all over the world and it is recognized as one of the major public health problems. Bariatric surgery is considered an appropriate therapeutic option for obesity with progressively increasing demands. The changes resulting from massive weight loss after bariatric surgery are related to numerous complications. This article will present the dermatological alterations that can be found after bariatric surgery. They will be subdivided into dermatoses that are secondary to metabolic and nutritional disorders, those derived from cutaneous structural modifications after major weight loss and the influence the latter may have in improving of certain dermatoses.

Background Melasma is an acquired, irregularly patterned, light to dark-brown hypermelanosis, with symmetric distribution mostly over the face. The aim of this study was to evaluate clinical characteristics and factors related to melasma in Brazilian patients. Methods This was a cross-sectional, multicenter study performed in Brazil. Investigators examined and questioned 953 patients over 18 years of age on clinical characteristics and other factors related to their melasma. Results Melasma was more prevalent in women (97.5%) and in Fitzpatrick skin phototypes II (12.8%), III (36.3%), and IV (39.7%). Skin phototypes II and III and family history of melasma had early onset of the disorder when compared with skin phototypes IV, V, and VI (P

Although the intradermal melanocytic nevi are benign lesions, many patients seek for dermatologists for their excision. However, there are no studies about the best method for this procedure. Objective: To compare in a randomized clinical trial the excision of intradermal melanocytic nevi in the face for shaving and elliptical excision with suture Methods: Patients with intradermal melanocytic nevi on the face were selected for removal by shaving or ellipse, randomly. The results were described regarding patient satisfaction and photographic records evaluated by a blinded physician. Results: 18 patients underwent excision of intradermal melanocytic nevi. The mean scar size after six months of the procedure was of 8,11mm for the excision in ellipse and 2,92mm for the shaving (p < 0.05). The mean score of the patients after six months was 9.67 (ellipse) and 9.57 (shaving) (p = 0.8). The mean by the blinded physician was of 7.78 (ellipse) and 7.86 (shaving) (p = 0.91). 28.6% of patients undergoing shaving had recurrence of the nevus. Conclusions: The two forms are of excision are equivalent concerning patients satisfaction and the judgment of medical team about the aesthetic results of the scar. However, ellipse with suture excision has the advantage of having a lower relapse

BACKGROUND: Skin diseases cause negative impact on the emotional state, social relationships and daily activities, due to the stigma caused by the appearance of the lesions. OBJECTIVE: This study aimed to assess the quality of life of pediatric patients with skin diseases attending a dermatology service, compare the scores obtained among the dermatoses found in the sample and associate them to the variables, in addition to observing how the skin disease specifically affects quality of life. METHODS: Cross-sectional study, with patients between 5 and 16 years attending the Dermatology Service of the University of Health Sciences of Porto Alegre, Brazil, between July 2010 and February 2011. The data collection instruments were the Children's Dermatology Life Quality Index questionnaire and the AUEQI questionnaire. RESULTS: A total of 161 patients were interviewed, with mean age of 9,66 years. The main dermatoses were atopic dermatitis (29.8%), warts (13%) and molluscum contagiosum (7.5%). Chronic diseases (73.9%) were the most prevalent. The overall mean Children's Dermatology Life Quality Index score was 5.01 for chronic dermatoses and 2.07 for acute illnesses, indicating a compromised quality of life among chronically ill patients. The comparison between the scores obtained with the AUEQI scale and the Children's Dermatology Life Quality Index scores indicates that the overall quality of life is less affected than the specific quality of life related to the dermatosis. CONCLUSIONS: The data presented reinforce how important it is that the patients, their families and caregivers understand the symptoms, triggers and treatment of the skin disease in question. This information facilitates adherence to the treatment and justifies the conduct adopted by the dermatologist. FUNDAMENTOS: Doenças dermatológicas, em razão dos estigmas pela aparência das lesões, são fonte de impacto negativo no estado emocional, relações sociais e atividades cotidianas. OBJETIVOS: Este estudo objetiva avaliar a qualidade de vida nos pacientes dermatológicos pediátricos em um centro de referência em dermatologia, comparar os índices de qualidade de vida entre as dermatoses e associá-los às variáveis, além de avaliar de que forma as dermatoses afetam a qualidade de vida especificamente. MÉTODOS: Estudo analítico transversal, pacientes entre 5 e 16 anos, do Serviço de Dermatologia da Universidade Federal de Ciências da Saúde de Porto Alegre, entre julho de 2010 e fevereiro de 2011. Instrumentos utilizados: questionário Índice Pediátrico de Qualidade de Vida em Dermatologia e escala AUQEI. RESULTADOS: Um total de 161 pacientes, média de idade de 9,66 anos. As principais dermatoses foram dermatite atópica (29,8%), verrugas vulgares (13%) e molusco contagioso (7,5%). Doenças crônicas (73,9%) foram mais prevalentes. A média do Índice Pediátrico de Qualidade de Vida em Dermatologia de 5,01 para dermatoses crônicas, e de 2,07 em agudas, indicando maior comprometimento da qualidade de vida entre os pacientes cronicamente enfermos. A comparação entre os escores obtivos com a escala AUEQI e o Índice Pediátrico de Qualidade de Vida em Dermatologia indicam que a qualidade de vida global é afetada com menor intensidade do que a relacionada especificamente à dermatose. CONCLUSÃO: Os dados obtidos reforçam a importância do entendimento dos sintomas, desencadeantes e da terapêutica da dermatose em questão pelos pacientes, por seus familiares e por seus cuidadores. Tais infomações facilitam a aderência ao tratamento e justificam a conduta adotada pelo dermatologista.

Pityriasis versicolor (PV) is a disease with worldwide distribution. Twelve different species of Malassezia yeast have been described. The objective of this study was to determine which species of Malassezia are more prevalent in patients with pityriasis versicolor. Samples were collected by scraping the lesions of 87 patients with a clinical suspicion of pityriasis versicolor. The samples were then sub- mitted to fungal microscopy and culture to identify the species. The species found were: Malassezia sym- podialis (30%), Malassezia furfur (25.7%), Malassezia globosa (22.7%), Malassezia restricta (12.1%), Malassezia obtusa (7.6%) and Malassezia slooffiae (1.5%).

FUNDAMENTOS: prurido é o sintoma mais freqüente nos pacientes nefropatas em hemodiálise. Parâmetros laboratoriais anormais têm sido encontrados, com dados conflitantes. OBJETIVO: relacionar a prevalência de prurido com alterações no metabolismo mineral de pacientes em hemodiálise. MÉTODOS: estudo caso-controle. Avaliados 105 pacientes, sendo os pacientes com prurido os casos, preencheram o questionário do protocolo de pesquisa e a escala análoga visual, os dados laboratoriais foram coletados dos prontuários eletrônicos. RESULTADOS: a média de idade foi de 51,9 anos, 59% dos pacientes eram homens e 43% dos pacientes tinham prurido. Xerodermia ocorreu em 45% dos pacientes. Níveis elevados de Ca foram demonstrados em 55% dos pacientes e 47% tinham prurido. Quanto ao fósforo 60% tinham valores elevados e 43% tinham prurido. A relação Ca/P foi normal em todos. O paratormônio mostrou-se elevado em 95% dos pacientes, todos referindo prurido. CONCLUSÃO: houve associação estatisticamente significativa entre o grupo de pacientes com prurido e xerodermia. Os níveis séricos de Cálcio, Fósforo, relação Ca/P, PTHi e o tamanho do dialisador não apresentaram associação estatisticamente significativa com o prurido. Logo, encontramos relação importante entre xerodermia e prurido, sem relação com os parâmetros laboratoriais avaliados. BACKGROUND: Uremic pruritus is the most frequent symptom in long-term hemodialysis patients. Abnormal laboratory parameters have been found with conflicting data. OBJECTIVE: To correlate the prevalence of pruritus with alterations in mineral metabolism in hemodialysis patients. METHODS: This was a case-control study. A hundred and five patients on maintenance hemodialysis were evaluated: a group of patients with pruritus and a control group. They answered a research protocol questionnaire; laboratory data were collected from medical records and the patients with pruritus filled out a visual analogue scale (VAS) to measure pruritus level. RESULTS: The mean age was 51.9 years; 59% of the patients were men and 43% of the patients had pruritus. Xeroderma occurred in 45% of the patients. High levels of calcium were demonstrated in 55% of the patients and 47% had pruritus. 60% of the patients had high phosphorus levels and 43% had pruritus. The Ca/P ratio was normal for all the patients. Parathyroid hormone was high in 95% of the patients, all of them referring pruritus. CONCLUSION: There was a statistically significant association between the group of patients with pruritus and xeroderma. Serum calcium and phosphorus levels, Ca/P ratio, PTHi and size of the dialyzer did not show a statistically significant association with pruritus. Therefore, we found an important relationship between xeroderma and pruritus, with no relation with the assessed laboratory parameters.

Duas irmãs com doença de Hailey-Hailey, com lesões recorrentes - uma em axilas e outra em região inguinal -, e resposta limitada aos tratamentos clássicos. Elas foram tratadas com aplicação de toxina botulínica tipo A. Observamos que houve importante melhora na paciente tratada na região inguinal e remissão completa na paciente em cujas axilas sofreram tratamento. Além disso, foi possível poupar uso de antibióticos sistêmicos e corticoides tópicos. O alto custo é um fator restritivo para uso rotineiro e estudos maiores são necessários para definir eficácia e relação custo-benefício dessa intervenção.

FUNDAMENTOS: Algumas dermatoses repercutem, pela sua aparência, na vida pessoal, profissional e social dos pacientes. Faz-se necessária a valorização desse tema visando-se à avaliação global desses indivíduos, para o estabelecimento de uma abordagem terapêutica mais eficaz. OBJETIVOS: Avaliar a qualidade de vida e a frequência de sofrimento psíquico nos pacientes em um centro de Dermatologia. MÉTODOS: Estudo transversal. Após consulta, aplicou-se o Índice de Qualidade de Vida para Dermatologia (DLQI) e o Self-Reported Questionnaire (SRQ-20). RESULTADOS: Foram entrevistados 1.000 pacientes. Não houve efeito da dermatose sobre a qualidade de vida em 21,5% deles; 34,2% apresentaram "pouco efeito", 21,6%, "efeito moderado", 19,3%, "grande efeito" e 3,4%, efeito extremo sobre a qualidade de vida. A correlação entre sofrimento psíquico e dermatoses não mostrou associação estatística significativa. Comparando-se os dois questionários, houve associação significante entre presença de sofrimento psíquico e pior qualidade de vida (p

FUNDAMENTOS: O prurido é um sintoma freqüente nos pacientes em hemodiálise. Tem etiologia não totalmente esclarecida e difícil manejo, o que piora de modo considerável a qualidade de vida dos doentes. OBJETIVOS: Avaliar o grau de prurido e sua influência na qualidade de vida dos pacientes renais crônicos em hemodiálise. MÉTODOS: Estudo transversal com pacientes renais crônicos em hemodiálise no Complexo Hospitalar Santa Casa de Porto Alegre, que apresentassem prurido sem outras dermatoses. Utilizou-se a escala análoga visual para mensuração do grau de prurido e o questionário do Índice de Qualidade de Vida para Dermatologia. RESULTADOS: Dos 200 pacientes avaliados, 69 (34,5%) apresentaram prurido, dos quais 16 (23%) de grau leve, 39 (56,5%) moderado e 14 (20,2%) grave. Quando analisada a qualidade de vida, verificou-se que em 14 (20,3%) não houve influência do prurido na qualidade de vida. Entretanto, para 26 pacientes (37,4%), o prurido teve um pequeno efeito, em nove (13%) houve efeito moderado, 13 (18,8%) foram afetados de maneira grave e em sete (10,1%) houve influência extremamente grave. CONCLUSÕES: Neste estudo, 57% dos indivíduos não demonstraram alterações importantes na qualidade de vida relacionadas ao prurido, mas um número significativo estava na faixa de muito e extremamente alterado, o que denota a necessidade de atenção ao tratamento deste sintoma neste grupo de pacientes. INTRODUCTION: Pruritus is a frequent symptom affecting patients on hemodialysis. Its etiology is not known and treatment is difficult. This symptom considerably worsens the patients’ quality of life. OBJECTIVES: To evaluate the degree of pruritus and its influence on the quality of life of patients on hemodialysis. METHODS: Patients with chronic renal disease on hemodialysis and presenting pruritus in a Hospital of Porto Alegre were enrolled in this transversal study. A visual analogue scale for measuring the degree of pruritus was used and the Dermatology Life Quality Index questionnaire was applied. RESULTS: Of 200 evaluated patients; 69 (34.5%) presented pruritus, of whom 16 (23%) of mild degree, 39 (56.5%) moderate, 14 (20.2%) severe. Quality of life assessment revealed that in 14 of the patients (20.3%) there was no influence of pruritus, in 26 (37.4%) there was a small effect, in nine (13%) a moderate effect, in 13 (18.8%) a serious effect and in seven (10.1%) there was an extremely serious influence of pruritus on the quality of life. CONCLUSIONS: In this study, 57% of the individuals did not demonstrate important alterations in the quality of life related to the pruritus. A significant number of patients on hemodialysis have their quality of life from moderately to extremely modified by pruritus, which demonstrates the need for treating this symptom.

Atopic Dermatitis is a chronic inflammatory skin disease that affects a large number of children and adults. The disease results from an interaction between genetic predisposition, host environment, skin barrier defects, and immunological factors. A major aggravating factor associated with Atopic Dermatitis is the presence of microorganisms on the patient's skin surface. Staphylococcus aureus and Streptococcus pyogenes, for instance, can exacerbate chronic skin inflammation. As a result, antimicrobials have often been prescribed to control the acute phase of the disease. However, increased bacterial resistance to antimicrobial agents has made it difficult for dermatologists to prescribe appropriate medication. In the presence of disseminated dermatitis with secondary infection, systemic antibiotics need to be prescribed; however, treatment should be individualized, in an attempt to find the most effective antibiotic with fewer side effects. Also, the medication should be used for as short as possible in order to minimize bacterial resistance. A dermatite atópica é uma doença inflamatória crônica da pele que afeta um grande número de crianças e adultos. A doença resulta da interação entre predisposição genética, fatores ambientais, defeitos da barreira cutânea e fatores imunológicos. Um dos grandes fatores agravantes associados à dermatite atópica é a presença de microorganismos na superfície cutânea desses pacientes. Staphylococcus aureus e Streptococcus pyogenes, por exemplo, podem exacerbar a inflamação crônica da pele. Como resultado, antimicrobianos são prescritos para controlar a fase aguda da doença. O constante crescimento da resistência bacteriana aos antimicrobianos tem tornado a escolha do mais adequado medicamento uma difícil decisão para os dermatologistas. Na presença de dermatite disseminada com infecção secundaria, antibióticos sistêmicos necessitam ser prescritos; no entanto, o tratamento deve ser individualizado, de forma a encontrar o antimicrobiano mais eficaz e com menores efeitos colaterais. Além disso, esse medicamento deve ser utilizado pelo menor tempo possível, a fim de minimizar a resistência bacteriana.

BACKGROUND: The skin is the primary interface of the human being with the external environment and the presence of skin diseases can have substantial effects on the quality of life. OBJECTIVE: This study aims to make a comparative evaluation of the quality of life of pediatric patients with atopic dermatitis, psoriasis and vitiligo and correlate the findings with the total body surface and the areas with the disease exposed to view. METHODS: The sample consisted of 118 patients with atopic dermatitis, vitiligo and psoriasis, aged between 5 and 16 years, who were asked to answer the Children's Dermatology Life Quality Index (CDLQI) questionnaire. A dermatological examination for the measurement of total body surface affected by the disease was performed. RESULTS: The three groups showed an impaired quality of life. Patients with atopic dermatitis and psoriasis showed a significantly greater impact on the QoL than the group with vitiligo. There is a trend towards impaired quality of life in patients from the three groups of dermatoses, which is related to increments in both the total affected area and affected area exposed to view (r = 0.428 and p

A lesão cutânea do eritema ab igne é caracterizada por eritema reticulado, hiperpigmentação, descamação fina, atrofia epidérmica e telangiectasias. Atualmente, a região lombar é a mais atingida, devido ao uso de bolsas de água quente, para alívio de dores crônicas, e por constantes exposições a calor profundo em sessões de fisioterapia. Os autores alertam sobre uma dermatose pouco diagnosticada e que talvez seja mais prevalente pela alta freqüência com que são realizados tratamentos fisioterápicos. The cutaneous lesion of erythema ab igne is characterized by a reticulate erythema, hyperpigmentation, fine scaling, epidermal atrophy and telangiectasis. Currently the lumbar region is the most affected, due to the use of hot water bottles to relieve chronic pains, and by constant exposure to deep heat in physiotherapy sessions. The authors call attention to a dermatosis that is not often diagnosed, and that may be more prevalent, because of the high frequency with which such physiotherapeutic treatments are performed.
