Perfil clínico de pacientes dermatológicos encaminhados para avaliação oftalmológica / Clinical profile of dermatological patients referred to ophthalmological evaluation

RESUMO Objetivo: Analisar o perfil clínico de pacientes em acompanhamento dermatológico encaminhados para avaliação oftalmológica. Métodos: A amostra foi composta de pacientes dermatológicos encaminhados para avaliação oftalmológica, nos anos de 2016 e de 2017. Estudou-se a concomitância de doenças dermatológicas com as afecções oftalmológicas por meio da coleta simultânea do histórico dermatológico (prontuários registrados com dados gerais e diagnóstico) e de dados da consulta oftalmológica após o encaminhamento. Resultados: Foram avaliados pela oftalmologia 224 pacientes, sendo 65% do sexo feminino, 80% caucasianos, com idade variando entre 1 mês e 85 anos. As situações cujo encaminhamento foi mais prevalente foram psoríase, lúpus, vitiligo e rosácea (18,3%, 13,8%, 12,9% e 10,7%, respectivamente). Fototerapia crônica e uso de hidroxicloroquina representaram 35,7% e 22,3% dos pacientes. Casos de neurofibromatose, micose fungoide, líquen plano, neoplasias de pele, atopias, pênfigo e esclerodermia também estiveram presentes. Cegueira legal foi detectada em 6%, e deficiências visuais ligadas a afecções dermatológicas foram verificadas em 16,5% dos casos. As alterações oculares mais prevalentes foram catarata (18,9%), blefarite (15,9%), pterígio (5,3%) e conjuntivite (5,3%). Conclusão: Encontrou-se elevada frequência de alterações oftalmológicas em uma população de pacientes com doenças dermatológicas. Assim, o estudo e a análise de manifestações oculares em pacientes dermatológicos podem auxiliar na detecção precoce e na prevenção de complicações.

ABSTRACT Objective: To analyze the clinical profile of patients under dermatological care and referred to ophthalmological evaluation. Methods: The sample comprised dermatology patients referred to ophthalmological evaluation in 2016 and 2017. The simultaneous occurrence of skin and ophthalmic diseases was studied, by collecting dermatological history (medical records containing general data and diagnosis) and ophthalmic consultation data following referral. Results: A total of 224 patients were assessed, 65% were female, 80% were white, and age varied between one month and 85 years. The conditions more often referred were psoriasis, lupus, vitiligo and rosacea (18.3%, 13.8%, 12.9% and 10.7%, respectively). Chronic phototherapy and use of hydroxychloroquine were observed in 35.7% and 22.3% of patients, respectively. Cases of neurofibromatosis, mycosis fungoides, lichen planus, skin cancer, atopic dermatitis, pemphigus and scleroderma were also reported. Legal blindness was detected in 6% and visual impairment related to skin conditions in 16.5% of patients. The most prevalent ocular changes were cataracts (18.9%), blepharitis (15.9%), pterygium (5.3%) and conjunctivitis (5.3%). Conclusion: A high frequency of ophthalmic changes in a population of dermatological patients was found. In this context, studying and analyzing ocular manifestations in dermatological patients could be useful in early detection and prevention of complications.

Profile of dermatological consultations in Brazil (2018)

Abstract: Background: Dermatological diseases are among the primary causes of the demand for basic health care. Studies on the frequency of dermatoses are important for the proper management of health planning. Objectives: To evaluate the nosological and behavioral profiles of dermatological consultations in Brazil. Methods: The Brazilian Society of Dermatology invited all of its members to complete an online form on patients who sought consultations from March 21-26, 2018. The form contained questions about patient demographics, consultation type according to the patient's funding, the municipality of the consultation, diagnosis, treatments and procedures. Diagnostic and therapeutic decisions were compared between subgroups. Results: Data from 9629 visits were recorded. The most frequent causes for consultation were acne (8.0%), photoaging (7.7%), nonmelanoma skin cancer (5.4%), and actinic keratosis (4.7%). The identified diseases had distinct patterns with regard to gender, skin color, geographic region, type of funding for the consultation, and age group. Concerning the medical conducts, photoprotection was indicated in 44% of consultations, surgical diagnostic procedures were performed in 7.3%, surgical therapeutic procedures were conducted in 19.2%, and cosmetic procedures were performed in 7.1%. Study limitations: Nonrandomized survey, with a sample period of one week. Conclusion: This research allowed us to identify the epidemiological profiles of the demands of outpatients for dermatologists in various contexts. The results also highlight the importance of aesthetic demands in privately funded consultations and the significance of diseases such as acne, nonmelanoma skin cancer, leprosy, and psoriasis to public health.

Seasonality of the hospitalizations at a dermatologic ward (2007-2017)

Abstract: There is little data in the literature concerning dermatologic admissions. Several diseases are seasonal in incidence and clinical worsening. We performed a survey of hospitalizations in the dermatology ward of a public hospital (April/2007 to May/2017). There were 1790 hospitalizations, whose main diagnoses were infectious dermatoses, neoplasias, psoriasis, bullous diseases and cutaneous ulcers. In winter, there were fewer hospitalizations for bacterial infections and urticaria, but more for leprosy. In summer, there were fewer hospitalizations for systemic and subcutaneous mycoses, but more for zoodermatoses and erythema multiforme. In the fall, more patients were admitted with mycoses. Spring favored urticaria and angioedema, but less cases of erythema multiforme and diabetic foot.

Prevalence of dermatoses in patients referred for evaluation in an outpatient clinic of specialties

Abstract: Background: Brazilian Unified Health System presents a long waiting period for a dermatology appointment, varying from 34 to 239 days. Objectives: Analyze the prevalence of cutaneous diseases evaluated by dermatologists in a specialized center, in patients referred from the primary care, and to present possible interventions for the primary units. Methods: Retrospective analyses of the International Codes of Diseases (ICD-10) described in every dermatology appointment in a specialty center in Sao Paulo from January 2014 to August 2015. Results: A total of 7.350 consultations were included. Superficial mycosis corresponded to 1,058 (14.4%) of the main complaints and dermatophytosis was the most frequently used ICD, corresponding to 481 individual consultations (6.5%), followed by onychomycosis, responsible for 464 consultations (6.3%), acne in 347 (4,7%). and contact dermatitis in 311 consultations (4,2%). Study limitations: The study was based on retrospective analysis of ICD described and no previous orientation for a solid use of the codes was performed to the dermatology team; consultations in which the ICD was not informed or a non-especific ICD was used were excluded; different dermatologists were responsible for the consultations. Conclusion: Superficial mycosis corresponded to 14.4% of the chief complaints in the studied period and was the most frequent cause of reference from primary care doctors to dermatologists. Prevalence data obtained in the present study could assist the capacitation policies in the primary care system, focusing the dermatology teaching in the most prevalent dermatological disorders.

A esporotricose é uma micose subcutânea de evolução subaguda a crônica, causada pelo fungo dimórfico e geofílico Sporothrix schenckii. A transmissão zoonótica vem recebendo destaque, tendo os felinos domésticos um importante papel epidemiológico na doença. Este trabalho pesquisa teve como objetivo diagnosticar casos de esporotricose em felinos domésticos atendidos no município de Campos dos Goytacazes/RJ, bem como correlacionar os casos positivos com os sinais clínicos observados nos mesmos, assim como fatores de risco tais quais sexo, animais castrados ou não, dentre outras características. Foram utilizados 100 felinos domésticos, portadores de lesões cutâneas suspeitas de esporotricose, os quais passaram por avaliação clínica minuciosa e preenchimento de fichas individuais. As lesões foram então selecionadas para coleta de material em suabes estéreis e posterior análise laboratorial, através da citologia e cultura fúngica. Dos 100 animais analisados, 66 (66%) foram positivos para Sporothrix spp., sendo 46 (69,6%) machos não castrados, 15 (22,7%) fêmeas não castradas, 4 (6,06%) fêmeas castradas e 1 (1,5%) macho castrado, os quais 89,3% tinham acesso à rua. Quanto à topografia lesional e estado clínico dos animais, 43 (65,2%) apresentavam lesões focais e 23 (34,8%) lesões disseminadas, onde 21 (31,8%) vieram à óbito ou foram submetidos a eutanásia por opção do tutor. Com os resultados dos exames foi possível a adequada prescrição do protocolo terapêutico e acompanhamento de 40 animais (60,6%), e nos casos dos felinos encaminhados (7,5%), foi reportado ao médico veterinário responsável o respectivo diagnóstico para que este escolhesse sua conduta terapêutica.(AU)

Impact on the quality of life of dermatological patients in southern Brazil / Impacto na qualidade de vida de pacientes dermatológicos no sul do Brasil

BACKGROUNDS: Skin diseases are extremely frequent and may affect quality of life; therefore, it is important to assess it and identify which factors are associated with it. OBJECTIVES: To assess quality of life and its associated factors in dermatological patients. METHODS: A cross-sectional study involving a sample of 548 patients seen at the Dermatology Outpatient Clinic of Sistema Único de Saúde (the Brazilian National Public Health System), University Hospital, Federal University of Rio Grande do Sul (RS). Information related to socio-demographic data, medical consultation and quality of life was collected by means of the Dermatology Life Quality Index. RESULTS: A median of 7 and a mean of 7.7 (SD = 5.0) were obtained with the Dermatology Life Quality Index. The skin diseases with higher scores on the Dermatology Life Quality Index were psoriasis (median = 15.5), vitiligo (median = 13), atopic dermatitis (median = 12) and acne (median = 10). With respect to factors associated with quality of life, it was found that younger, single patients with a low income, one skin disease and longer disease duration presented poorer quality of life. CONCLUSION: The assessment of the impact of dermatoses on patients' quality of life is important for clinical management. It is essential to detect patients at higher risk of experiencing worse quality of life in order to treat them in a more integrated way.

FUNDAMENTOS: As doenças de pele são extremamente freqüentes e os pacientes podem ter a qualidade de vida afetada. Assim é importante medi-la, bem como verificar quais os fatores que podem estar associados. OBJETIVOS: Verificar a qualidade de vida em pacientes dermatológicos e os fatores associados. MÉTODOS: Estudo tranversal com uma amostra de 548 pacientes atendidos no ambulatório de dermatologia do Sistema Único de Saúde do Hospital Universitário da Universidade Federal do Rio Grande. As informações foram coletadas em um questionário pré-codificado e referiam-se à dados sócio-demográficos, da consulta e qualidade de vida. RESULTADOS: O escore total do Dermatology Life Quality Index foi uma mediana de 7 e uma média de 7,7 (DP=5,0). As dermatoses com escore maior no Dermatology Life Quality Index foram psoríase (mediana = 15,5), vitiligo (mediana =13), dermatite atópica (mediana = 12), acne (mediana=10). Com respeito aos fatores associados à qualidade de vida, identificou-se que pacientes mais jovens, com menor renda, solteiros, com uma dermatose e com um tempo maior de evolução da doença, apresentam pior qualidade de vida. CONCLUSÃO: A avaliação do impacto na qualidade de vida em pacientes com dermatoses é importante para o manejo clínico. É essencial a detecção daqueles pacientes com maior risco de apresentar uma qualidade de vida pior, para poder abordá-los de uma forma mais integrada.

Prevalência de dermatoses em escolares na região do ABC paulista / Prevalence of dermatosis in scholars in the region of ABC paulista

FUNDAMENTOS: A literatura mostra que a prevalência de doenças dermatológicas em crianças e adolescentes com idades de 7-14 anos é consideravelmente significante, bem como a falta de tratamento e possível agravamento da situação. OBJETIVOS: Realização de uma análise investigativa para apontar a prevalência de dermatoses em indivíduos de 714 anos, assim como para verificar se estas estão diretamente ligadas ou não a suas respectivas situações socioeconômicas. MÉTODOS: Analisaram-se 200 crianças e adolescentes com idades de 7-14 anos, entre os meses de agosto e novembro de 2006, sendo 100 crianças em duas escolas públicas localizadas na periferia e 100 em duas escolas particulares localizadas em bairro de classe média alta na cidade de Santo André, Grande São Paulo. Para tanto, utilizou-se o método investigativo, com exame clínico de toda a superfície corpórea, de mucosas e de gânglios palpáveis, sendo a amostra populacional analisada de acordo com o teste qui-quadrado. RESULTADOS: 87,5 por cento das crianças apresentaram algum tipo de dermatose; encontraram-se 46 dermatoses, destacando-se: a) nevos melânicos (p<0,001); b) acne grau II (p=0,004); c) pitiríase alba (p<0,001); d) livedo reticular (p=0,025); e) pediculose (p<0,001); f) asteatose (p<0,001); g) dermatite friccional (p=0,007). Constatou-se uma pequena predominância das dermatoses nas crianças das escolas públicas (53,14 por cento). CONCLUSÕES: A amostra dessa população indicou que 87,5 por cento das crianças apresentaram dermatoses, uma prevalência muito maior do que a encontrada na literatura (30 por cento a 50 por cento) e uma prevalência discretamente mais elevada nas escolas públicas. O estudo mostrou a indiferença dos pais e responsáveis, o que aponta para a necessidade de interferência de políticas públicas, cuja falta, certamente, é responsável por esse índice elevado e possível agravamento da prevalência.

BACKGROUND: Literature shows that prevalence of skin diseases in children and adolescents aged 7-14 years is very significant, as well as lack of treatment worsening the situation. OBJECTIVES: An investigative analysis was conducted to determine the prevalence of skin diseases in individuals 714 years and focus on whether or not they are related directly to their respective socio-economic status. METHODS: 200 children and adolescents were examined aged 7-14 years,between August and November 2006,100 children in two public schools located in the periphery and 100 in two private schools located in upper middleclass neighborhood in Santo André,located in São Paulo.Investigative method used was the clinical examination of the whole skin, mucous areas and palpable ganglia,and the population sample analyzed according to the chi-square. RESULTS: 87.5 percent of children had some skin disease.46 dermatoses were found,the most important:a)melanocytic nevi (p <0.001);b)acne grade II (p = 0.004);c)pityriasis alba (p <0.001);d)livedo reticularis (p = 0.025); e)pediculosis (p <0.001);f)asteatosis (p <0.001);g) frictional dermatitis (p = 0.007).Small prevalence of skin diseases was observed in children in public schools (53.14 percent). CONCLUSIONS: This population sample indicated that 87.5 percent of children had skin diseases,which prevalence was much higher than those found in the literature(30-50 percent),showing a lightly enhanced prevalence in public schools.The study showed the neglect of parents and caregivers,indicating the need for interference from public policy,which lack certainly is responsible for high rate and can increase it.

Manifestações cutâneas na doença renal terminal / Cutaneous manifestations in end-stage renal disease

A prevalência da doença renal crônica aumentou nos últimos anos. Os efeitos dessa doença são complexos e podem levar à disfunção de múltiplos órgãos, entre eles, a pele. A maioria dos pacientes apresenta pelo menos uma alteração dermatológica. Algumas vezes, esses sintomas podem ser o primeiro sinal evidente de doença renal. Este artigo aborda as manifestações cutâneas relacionadas a disfunção renal grave ou doença renal terminal, divididas em não específicas e específicas, revisando quadro clínico, etiopatogenia e opções terapêuticas dessas dermatoses. Seu reconhecimento e trata mento precoces diminuem a morbidade, melhorando a qualidade de vida desses doentes.

The prevalence of chronic kidney disease has increased over the last years. The effects of this disease are complex and may lead to dysfunction of multiple organs, including the skin, with most patients presenting with at least one dermatologic alteration. Sometimes these symptoms can be the first clear sign of kidney disease. This article discusses the skin manifestations related to severe renal impairment or end-stage renal disease (ESRD), which are divided into nonspecific and specific, and reviews the clinical features, etiopathogenesis and therapeutic options for these dermatoses. Early recognition and treatment reduce morbidity and improve these patients' quality of life.

Aplicación de la teledermatología asincrónica en usuarios de la comuna de Yerbas Buenas, Región del Maule, Chile / Effectiveness of asynchronous teledermatology in users of the rural health center in Chile

La teledermatología (TD) revoluciona la atención en dermatología, facilitando su acceso a regiones remotas. La TD asincrónica (TDA), utilizada para el diagnóstico dermatológico a través del envío de información mediante e-mail, ha sido implementada en forma limitada en Chile. El objetivo de este estudio fue analizar la efectividad y la satisfacción usuaria (SU) de la TDA en un centro de salud rural de Chile. Se diseño un sistema de teleconsultas, capacitando a los médicos generales en patología dermatológica más frecuente y se realizó contrarreferencia. Se analizaron 172 teleconsultas. Las patologías más frecuentes fueron: acné (11,1 por ciento), onicomicosis (8,7 por ciento), psoriasis (4,1 por ciento), dermatitis de contacto (4,1 por ciento) y verrugas (4,1 por ciento), Se encontró alta concordancia diagnóstica (CD) entre médicos generales y especialista (88,3 por ciento). La SU general alcanzó un 97 por ciento y se logró la resolución del 99,4 por ciento de las teleconsultas. La TDA permite proporcionar atención dermatológica a distancia, lo que permitiría favorecer a diversas localidades rurales de Chile.

Teledermatology (TD) revolutionizes the delivery of dermatology services by facilitating the access to specialist services at a distance. Asynchronous TD (ATD) is used for skin diseases diagnosis by sending information and images through e-mail. Its implementation in Chile has been limited. The purpose of this study was to analize the effectiveness and the user satisfaction (US) of the application of ATD in a rural helath center in Chile. A teleconsultation system was designed, primary care general practitioners were trained in dermatological diagnosis and implementation of the cross-refertence was developed. We assessed 172 teleconsultations. The most frequent pathologies were acne (11,1 percent), onychomycosis (8,7 percent), psoriasis (4,1 percent), contact dermatitis (4,1 percent) and warts (4,1 percent). The diagnosis concordance (DC) was 88,3 percent and the general US reached 97 percent. Diagnostic and therapeutic resolution was achieved in 99,4 percent of the teleconsultations. ATD was able to provide a distant dermatological assistance, helping several rural areas of Chile.

Cutaneous manifestations of internal malignancies in a tertiary health care hospital of a developing country / Manifestações cutâneas de doenças malignas em um hospital terciário de um país em desenvolvimento

In a public hospital in Lima, Peru, 24 patients with 16 types of paraneoplastic dermatoses were identified by data collection. The most frequent dermatosis was dermatomyositis (four patients). The other dermatoses were malignant acanthosis nigricans, palmoplantar keratoderma, bullous dermatoses, lymphomatoid papulosis, edematous scarring vasculitic panniculitis, Norwegian scabies, primary systemic amyloidosis, necrolytic migratory erythema, infective dermatitis, pancreatic panniculitis, generalized pruritus, Lesser-Trelat syndrome, and acquired ichthyosis. Most of these paraneoplastic dermatoses were diagnosed before (45.8 percent) or at the time of (38.5 percent) the diagnosis of the underlying malignancy. The most frequent underlying malignancies were lymphoma, adenocarcinomas of the upper digestive tract, and malignant neoplasms of the pancreas. The average age of the patients was 47.0 ± 16.9 years and the length of the disease since diagnosis was 13.7 months. The mortality rate was 75 percent. Paraneoplastic dermatoses are rare dermatologic entities that are difficult to diagnose. Surveillance is also hampered when patients do not have easy access to health care centers due to financial and geographical issues. However, when identified, they might facilitate the early diagnosis of an associated tumor and contribute to increase the surveillance of patients.

Em um hospital público em Lima, Peru, 24 pacientes com 16 tipos de dermatoses paraneoplásicas foram identificados por meio de coleta de dados. A dermatose mais frequente foi dermatomiosite (quatro pacientes). As outras dermatoses foram acantose maligna, queratodermia palmoplantar, dermatoses bolhosas, papulose linfomatóide, cicatriz edematosa, paniculite e vasculite, escabiose norueguesa, amiloidose sistêmica primária, eritema necrolítico migratório, dermatite infecciosa, paniculite pancreática, prurido generalizado, sinal de Leser-Trelat e ictiose adquirida. Grande parte dessas dermatoses foi diagnosticada antes (45,8 por cento) ou no momento (38,5 por cento) do diagnóstico do tumor subjacente. Os tumores malignos mais frequentes foram linfoma, adenocarcinomas do trato digestivo superior e neoplasias malignas do pâncreas. A idade média dos pacientes foi de 47.0 ± 16.9 anos e a duração da doença desde o diagnóstico foi de 13,7 meses. A taxa de mortalidade foi de 75 por cento. Dermatoses paraneoplásicas são condições dermatológicas raras de difícil diagnóstico. O controle também é prejudicado quando pacientes não têm acesso fácil à centros de saúde por questões financeiras ou geográficas. No entanto, quando identificadas, elas podem facilitar o diagnóstico precoce de um tumor associado e contribuir para um aumento do controle dos pacientes.

Colagenosis perforante reactiva adquirida: Caso clínico / Acquired reactive perforating collagenosis: Report of two cases

Acquired reactive perforating collagenosis is a perforating dermatosis characterized by transepidermal elimination of collagen. It is frequently associated to diabetes mellitus and chronic renal insuffciency, but it is also related to other systemic diseases. The lesions tend to resolve once the underlying condition is treated. We report two patients with the condition. A 65 year-old diabetic female on hemodialysis consulted for multiple itching cutaneous ulcers lasting one year. On physical examination, hyperpigmented papules and nodules were observed. A 65 year-old female with chronic renal failure in hemodialysis consulted for itching lesions in hands, forearms and arms. On physical examination, hyperpigmented lesions with ulcers, erosions and crusts were observed. In both cases, the pathological study of the lesions disclosed a reactive perforating collagenosis.

Concordância entre diagnósticos dermatológicos obtidos por consulta presencial e por análise de imagens digitais / Agreement between dermatological diagnoses made by live examination compared to analysis of digital images

FUNDAMENTOS: A teledermatologia, pouco utilizada no Brasil e com iniciativas incipientes no Amazonas, necessita de estudos para demonstrar sua factibilidade e eficácia. OBJETIVOS: Avaliar a eficácia de um método assíncrono de teledermatologia, utilizando recursos tecnológicos simples e de baixo custo. MÉTODOS: Cento e setenta e quatro pacientes foram examinados por quatro dermatologistas; dois efetuaram diagnóstico presencial (A1 e A2) e dois por meio de imagens das lesões e história clínica (B1 e B2). Foi investigada a concordância entre as avaliações presenciais e por imagens. RESULTADOS: A concordância do diagnóstico principal entre os examinadores presenciais (A1 e A2) foi de 83,3 por cento e entre os de imagens (B1 e B2), de 81 por cento. A concordância entre o diagnóstico principal estabelecido pelo método presencial e o obtido por meio de imagens variou de 78,2 por cento a 83,9 por cento. CONCLUSÃO: O diagnóstico de doenças dermatológicas realizado por imagens digitais demonstrou concordância ótima quando comparado àquele realizado com a presença física do paciente.

BACKGROUND: Teledermatology is seldom used in Brazil, although some incipient initiatives have been implemented in the state of Amazonas. Further studies are still required to confirm the feasibility and efficacy of this diagnostic tool. OBJECTIVES: To evaluate the efficacy of an asynchronous method of teledermatology using simple, inexpensive technological resources. METHODS: One hundred and seventy-four patients were examined by four dermatologists, two clinic-based dermatologists, who diagnosed the patients following live examination (A1 and A2), and two consultant specialists in image dermatology, who reached diagnoses by examining images of the lesions and the patients' clinical histories (B1 and B2). The agreement between live examination and examination of images was evaluated. RESULTS: Agreement between the two live examiners (A1 and A2) with respect to the principal diagnosis was 83.3 percent compared to 81.0 percent between the physicians who diagnosed by examining images (B1 and B2). Agreement between the principal diagnosis established by live examination and that obtained from examining images ranged from 78.2 percent to 83.9 percent, CONCLUSION: Agreement between diagnoses of dermatological diseases reached following examination of digital images and those reached following live examination of the patient was excellent.

Diagnóstico dermatológico: correlación entre médicos de atención primaria de salud y médicos dermatólogos / Diagnostic concordance between of primary care physicians and dermatologist

En Chile los médicos de Atención Primaria (AP) diagnostican y tratan gran cantidad de enfermedades de la piel. Sin embargo, muchos pacientes requieren ser referidos al Nivel Secundario para ser evaluados por especialistas. Objetivo: El presente estudio tiene como propósito analizar la concordancia del diagnóstico dermatológico realizado por los médicos de AP. Método: Se realizó un estudio retrospectivo en el que se incluyeron 1.478 pacientes referidos desde la AP a la Unidad de Dermatología en el Centro de Referencia de Salud (CRS) Cordillera entre enero de 2005 y enero de 2006. Se registraron sexo, edad, patología cutánea, época del año de la consulta y tiempo de espera para ser evaluados por dermatólogos. Para analizar la concordancia diagnóstico entre el médico general y el dermatólogo se utilizó el índice Kappa (IK), que se clasifica en seis categorías: sin acuerdo (KI < O), insignificante (O < KI > 0,2), discreto (0,21 < KI > 0,40), moderado (0,41 < KI > 0,60), sustancial (0,61 < KI > 0,80) y casi perfecto (0,81 < KI > 1,00). Resultados: La edad promedio de la muestra fue de 34.7 años. 63,8% de las consultas correspondieron a mujeres y 36,2% a varones. Los diagnósticos más frecuentes en la AP fueron: nevi (21,04%), verrugas virales (10,96%), dermatitis inespecífica (6,63%), acné (6,02%), dermatitis atópica (5,4%) y psoriasis (4,67%). Los diagnósticos más frecuentes en Dermatología fueron: nevi (13,80%), verrugas virales (8,19%), acné (6,09%), queratosis seborreico (5,63%) y psoriasis (3,92%). La concordancia diagnóstico (CD) global fue moderada (IK = 0,563), obteniéndose el más alto para acné (IK = 0,899) y alopecia (IK = 0,835), y el más bajo en queratosis seborreico (IK = 0,081) y melanoma (IK = 0,186). Conclusiones: La CD entre médicos de AP y dermatólogos es moderada. Es fundamentar elaborar estrategías...

In Chile, primary care (PC) physicians diagnose and treat large amount of skin diseases; however, a large number of patients are referred to the hospital to be en by dermatologists. Objective: The purpose of the present investigation was to analyse the accuracy of PC physicians in the skin diagnosis diseases. Method: A retrospective analysis of clinical data was performed including 1,478 patients requiring dermatology evaluation at the Dermatology Unit, Centro de Referencia de Salud (CRS) Cordillera, between January 2005 and January 2006. Information about skin disease, sex, age, season consultation and waiting time to see a dermatologist was collected. Kappa index (KI) was used to determine the clinic diagnostic accuracy between the PC physicians and the dermatologists. KI is classified in 6 categories: without agreement (KI < O), insignificant (O < KI > 0.2), discrete (0.21 < KI 0.40), moderate (0.41 < KI > 0.60), substantial (0.61 < KI 0.80) y almost perfect (0.81 < KI > 1.00). Results: The average of age was 34.7 years. 63.8% we females and 36.2% were males. The more frequent skin diagnosis in PC were: nevi (21.04%), warts (10.96%), nonspecific¡ dermatitis (6.63%), acne (6.02%), atopic dermatitis (5.4%) al psoriasis (4.67%). The more frequent skin diagnosis by the dermatologist was: nevi (13.80%), warts (8,19%), acne (6.09%) seborrheic keratosis (5.63%) and psoriasis (3.92%). The general diagnostic concordance (DC) was moderate (KI = 0.56: showing that the highest KI was observed for acne (KI = 0.899) and alopecia (KI = 0.835) and the lowest was for seborrheic keratosis (KI = 0.081) and melanoma (KI = 0.186). Conclusions: The diagnostic correlation between PC physician and dermatologists is moderate. More innovative strategies are needed to improve training in PC physicians to enhance their accurate skin diagnosis.

Estudo nosológico das dermatoses diagnosticadas no hospital da Universidade Federal de Juiz de Fora / Dermatoses diagnosed at the university hospital of the Federal University of Juiz de Fora

O censo dermatológico das diversas regiões brasileiras apresenta inegável importância para a Sociedade Brasileira de Dermatologia no intuito de se priorizar também seu papel social, assim como sua função no desenvolvimento da política de saúde do país. O objetivo do trabalho é o levantamento nosológico das dermatoses mais freqüentes de uma ampla região que abrange parte do Estado de Minas Gerais e do Estado do Rio de Janeiro, com a finalidade de fornecer dados para posteriores trabalhos e iniciativas afins específicas. Foram avaliados 14.784 prontuários dermatológicos referentes ao período de 02 de fevereiro de 2003 a 02 de fevereiro de 2006. Deste total, ao excluírem-se os retornos, obtiveram-se um total de 9.031 pacientes atendidos, valor referente ao número de patologias diagnosticadas e tratadas no Serviço de Dermatologia do Hospital Universitário da Universidade Federal de Juiz de Fora. Os diagnósticos foram subdivididos de forma compacta e didática. Os resultados mais frequentes foram Tumores Cutâneos com 19,9% do total; Infecções Cutâneas com 19,89%; Eczemas com 13,56% e Afecções dos Anexos com 10,56%. Quanto às infecções, estas representam um grande percentual dos casos analisados, o que se deve provavelmente ao baixo nível socioeconômico dos pacientes em estudo. O presente Censo Dermatológico fornece subsídios para as diversas instâncias governamentais no planejamento das políticas de saúde na área da dermatologia, assim como para os programas de formação em dermatologia.

A dermatological survey of the different Brazilian regions provides scope for the Brazilian Dermatology Society to both play its social role and influence the national health policies. The objective of this study is the data-gathering nosological survey of the most frequently diagnosed dermatological conditions in a region comprising part of the states of Minas Gerais and Rio de Janeiro, Brazil. 14.784 medical records of Dermatology from the period February 2, 2003 to February 2, 2006 were assessed.After exclusion of follow-up visits, 9.031 patients were seen at the Dermatology Clinic. Diagnoses were clustered in a compact and didatic way. The results were that 19.9% of the patients were diagnosed with skin tumors, 19.89% with skin infections, 13.56% with eczema, and 10.56% with infection of the skin annexes. The low socioeconomic status of the patients is likely to account for the high percentage of skin infections. This dermatological census informs different government levels about priorities for health policies and professional education.

Prevalência de dermatoses em idosos residentes em instituição de longa permanência / Prevalence of dermatoses in residents of institutions for the elderly

OBJETIVOS: Determinar a prevalência das afecções dermatológicas em 75 idosos residentes em instituição de longa permanência na cidade de Santos-SP, e confrontar os achados com revisão da literatura. MÉTODOS: Setenta e cinco idosos foram submetidos a exame dermatológico. Com os dados obtidos calculou-se a prevalência, o número médio por paciente e a freqüência de dermatoses. Foi ainda analisado a distribuição nos subgrupos sexo, raça, faixa etária e nos subgrupos principais de dermatoses. RESULTADOS: O número total de dermatoses diagnosticadas foi 280, o número médio por paciente foi 3,73 e o número total de tipos de dermatoses foi 32. A prevalência das principais dermatoses encontradas foi: melanose solar (53,3 por cento), queratose seborréica (46,6 por cento), onicomicose (37,3 por cento), nevo rubi (33,3 por cento), púrpura senil (29,3 por cento), xerose (14,6 por cento), escabiose (12,0 por cento) e neoplasia maligna (1,3 por cento). A distribuição das dermatoses foi 70 por cento (IC95 por cento: 59 por cento a 81 por cento) maior no sexo feminino do que no masculino. CONCLUSÃO: Apesar da pequena casuística, os dados obtidos são compatíveis com os poucos relatos disponíveis na literatura. Este estudo de prevalência definiu a distribuição de dermatoses em uma fração da população de idosos. Entretanto, os dados agregados de casuísticas subseqüentes podem permitir tornar os dados mais precisos, cuja relevância é indiscutível na orientação de medidas de saúde individual e coletiva.

OBJECTIVE: To determine the prevalence of dermatoses in 75 elderly residents in an institution of long permanence in the city of Santos, and to compare findings with those in literature. METHODS: Seventy five healthy elderly persons were submitted to a dermatological exam. The prevalence, the average number per elderly person and the frequency of dermatoses were calculated from the data collected. An analysis was then made of the distribution in the subgroups of, gender, race, age bracket as well as of dermatosis in the main sub-groups. RESULTS: The total number of diagnoses of dermatosis was 280 with an average number of 3. 73/ per elderly person and 32 different types of dermatosis: were found. The prevalence of the dermatosis most often found was respectively: melanosis (53.3 percent), seborrheic keratosis (46.6 percent), onychomycosis (37.3 percent), nevus (33.3 percent), senile purpura (29.3 percent), xerosis (14.6 percent), scabies (12.0 percent) and malignant neoplasm (1.3 percent). The distribution of dermatosis was 70 percent (CI95 percent: 59 percent to 81 percent) higher in the female population than in the male. CONCLUSION: Notwithstanding the small number of cases, these data are compatible with the few reports available in literature. This study of prevalence defined the distribution of dermatosis in a fraction of the elderly population. However the aggregate data of subsequent casuistries may provide the more precise information whose relevance is undeniable in the orientation of individual and collective future health measures.

Caracterización clínico-epidemiológica telefónica de la mordedura por araña de rincón, en un centro de información toxicológica de Chile, durante el año 2005 / Prevalence and epidemiology of Loxosceles laeta bite. Analysis of consultations to a poison control center

Background: Loxoscelism is caused by the bite of spider Loxosceles laeta. It can cause a cutaneous or systemic syndrome. Aim: To determine the epidemiol¢gica! and clinical features of patients bitten by the Chilean recluse spider (Loxosceles laeta). Material and Methods: All communications received at a telephonic orientation center for intoxications during 2005 were analyzed, selecting those who involved patients with symptoms that suggested loxoscelism (i.e., pain, burning sensation, blue area, hematuria, fever or myalgia). These were derived to the emergency room for confirmation of the diagnosis. Forty-eight hours after the initial communication, patients were contacted by phone to find out about the definitive diagnosis. The variables analyzed were: gender, age, geographical location, time since exposure, part of the body involved, clinical signs and definitive diagnosis. Results: Of 2,831 telephonic consultations with suspected loxoscelism, the diagnosis was confirmed in 287. All of these patients had cutaneous loxoscelism and only 7.3 percent of them developed visceral loxoscelism. Fifty six percent of patients with loxoscelism presented two or more clinical signs. The most common were a blue area, pain and a burning sensation, in 69 percent, 58 percent and 38 percent of patients, respectively. Fifty-one percent of patients developed signs within the first 12 hours. All patients with visceral syndrome presented with hemoglobinuria. No cases of loxoscelism were registered in areas located southern than the Xth region of Chile. There were no fatalities attributed to loxoscelism. Conclusions: Most cases of loxoscelism of this series were cutaneous. The population must be educated about the clinical signs of spider bite to seek early and adequate medical treatment.

Análisis de consultas dermatológicas en una clínica privada en Santiago de Chile: experiencia de 20 años, 1985 - 2005 / Dermatologic consultation in a private clinic in Santiago de Chile: 20 years experience

Chile se encuentra pasando por una fase de transición demográfica y epidemiológica. No existe información a nivel nacional sobre la forma como esta transición influye en las causas de consulta dermatológica. El propósito de este trabajo es caracterizar las principales causas de consulta por enfermedades a la piel en Chile, durante los últimos 20 años, en un centro del subsistema privado de salud. Los resultados confirman que la patología infecciosa (23,6 por ciento en hombres y 19 por ciento en mujeres), los nevi (12,5 por ciento en hombres y 11,9 por ciento en mujeres) y las lesiones por daño actínico (7,8 por ciento en hombres y 9,7 por ciento en mujeres) son las causas más frecuentes de consulta. Lo anterior confirma que en el país existe, a nivel de morbilidad dermatológica, incluso en el nivel privado, una coexistencia entre patología de los países menos desarrollados y patología propia de sociedades industrializadas.

Chile is undergoing a demographic and epidemiological transition. No local information is yet available regarding how this transition may affect dermatological consultation. This study aims to characterize the main causes of dermatological consultation in a private center in Santiago, Chile, during the last twenty years. Results show that infectious diseases (23.6 percent in men, 19 percent in women), nevi (12.5 percent in men, 11.9 percent in women) and actinic lesions (7.8 percent in men, 9.7 percent in women) are the main causes of consultation. These findings confirm that, even when the setting is private - in a Chilean dermatology Chile, pathologies that are more frequent in developing nations coexist with those more common in developed nations.
