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.

Abstract: Background: Acne vulgaris is a pilosebaceous follicle disorder affecting over 85% of adolescents to some degree. It frequently causes psychological distress that may persist into adulthood due to scarring. Little information about post-acne scarring epidemiology is available. Objectives: To describe prevalence, distribution patterns and associated factors of acne scarring in young males, drawing on a representative population sample from a southern Brazilian city. Methods: A cross-sectional study was undertaken during presentation for military service, which is compulsory for all 18-year-old males. A questionnaire was applied, covering topics like diet, smoking habits, ethnicity, family structure, socio-economic level, as well as specific questions about active acne and resulting scars. Dermatologists conducted the clinical examination. Results: A total of 2,201 male adolescents were interviewed and examined. The overall prevalence of acne scarring was 22%. The malar region was the most frequently involved, present in 80% of affected individuals, followed by the frontal region (31.5%), back (17%), anterior chest (8.2%) and mentonian region (6.4%). Correlation between the intensity of clinical acne and the presence of scars was found, but no association was observed with educational level, smoking, ethnicity, obesity or socio-economic status. Conclusions: There is a high prevalence of acne scars among this population. This is the first study to ascertain a correlation between acne scarring and factors such as socio-economic status and educational level. The direct relation between acne severity and scarring indicates that prompt and effective treatment is the best way to reduce scarring.

The selection of instruments that will be used to collect data is a crucial step in the research process. Validity and reliability of the collected data and, above all, their potential comparability with data from previous investigations must be prioritized during this phase. We present a decision tree, which is intended to guide the selection of the instruments employed in research projects. Studies conducted along these lines have greater potential to broaden the knowledge on the studied subject and contribute to addressing truly socially relevant needs.

BACKGROUND: Acne vulgaris has high prevalence, disturbing quality of life during adolescence. OBJECTIVES: To measure dissastifaction and acne in 18-year-old male individuals and its associated factors. METHODS: A questionnaire was applied by trained interviewers to all boys during selection for the military service. Dissatisfaction and acne was evaluated using a self-administered face scale. Facial, prestrernal and dorsal acne were evaluated separately. RESULTS: A total of 2,200 adolescents, aged 18 years, were interviewed. Among these, 1,678 had acne on the face and 974 (54.05%) showed some degree of dissatisfaction. Regarding the impact of acne located on the chest, 326 out of 686 adolescents (47.52%) reported dissatisfaction. For acne located on the back, 568 out of 1,103 affected individuals (51.50%) showed dissatisfaction. Facial / dorsal acne and dissatisfaction were statistically associated with lower income, lower education levels and with non-whites. Presternal acne and dissatisfaction were statistically asssociated with lower income and lower education levels. CONCLUSION: This population-based study found a high prevalence of acne on the face, back and chest, with high rates of dissatisfaction. .

The importance of estimating sample sizes is rarely understood by researchers, when planning a study. This paper aims to highlight the centrality of sample size estimations in health research. Examples that help in understanding the basic concepts involved in their calculation are presented. The scenarios covered are based more on the epidemiological reasoning and less on mathematical formulae. Proper calculation of the number of participants in a study diminishes the likelihood of errors, which are often associated with adverse consequences in terms of economic, ethical and health aspects.

The present paper aims to provide basic guidelines to present epidemiological data using tables and graphs in Dermatology. Although simple, the preparation of tables and graphs should follow basic recommendations, which make it much easier to understand the data under analysis and to promote accurate communication in science. Additionally, this paper deals with other basic concepts in epidemiology, such as variable, observation, and data, which are useful both in the exchange of information between researchers and in the planning and conception of a research project.

BACKGROUND: Prevalence of tattoos is around 10-26% in men and 10-22% in women, and can involve negative effects such as: regret, removal attempts, physical and biological changes of the skin and association with some viral diseases. OBJECTIVE: to determine the prevalence, characteristics and factors associated with tattoos in recruiters joining the military. METHODS: the recruiters were examined by dermatologists that documented the presence or absence of tattoos, as well as their sizes, colors, designs and patterns, and whether they needed a parent's consent to get a tattoo. RESULTS: 1,968 recruiters were examined and the prevalence of tattoos was 10.82% (213), 141 (66.20%) had a single tattoo, 44 (20.66%) two tattoos, 15 (7.04%) three tattoos, 9 (4.23%) four tattoos, and 4 (1.88%) had more than four. Of the total sample, 168 (80.77%) reported getting the first tattoo before the age of 18. 158 (74.53%) were monochromatic. In relation to size, 108 (50.70%) had tattoos of up to 10 cm, 75 (35.21%) had tattoos measuring between 11-20cm, while 30 had ones over 21cm (14.09%). CONCLUSIONS: The population studied had a high prevalence of tattoos for their age, the percentage of complex (large and polychromatic) tattoos was also high. .

FUNDAMENTOS: Estima-se que a prevalência de tatuagens seja por volta de 10-26% em homens e 10-22% em mulheres, e estas trazem como consequência desdobramentos como: arrependimento, tentativas de remoção, alterações físicas e biológicas da pele e associação com soro positividade para doenças virais. OBJETIVOS: determinar a prevalência, características e fatores associados a tatuagens em alistandos do exército. MÉTODOS: Os alistandos foram entrevistados e examinados por dermatologistas, os quais anotaram a presença ou não de tatuagem , seus tamanhos, suas cores, padrões de desenhos e se havia permissão dos responsáveis para sua execução. RESULTADOS: Foram examinados 1.968 alistandos e a prevalência de tatuagens foi de 10,82% (213), 141 (66,20%) tinham tatuagem única, 44 (20,66%) tinham duas tatuagens, 15 (7,04%) tinham três tatuagens, 9 (4,23%) tinham quatro tatuagens e 4 (1,88%) tinham mais que quatro tatuagens; 168 (80.77%) informaram ter feito a primeira tatuagem antes de completar 18 anos de idade. 158 (74,53%) eram monocromáticas. Em relação ao tamanho no seu maior eixo temos que 108 (50,70%) tinham tatuagens com até 10 cm, 75 (35,21%) tinham entre 11 e 20 cm e com mais de 21 centimetros 30 (14,09%). CONCLUSÕES: a população estudada apresenta uma prevalência alta de tatuagens para a idade, e o percentual de tatuagens complexas (grandes e policromáticas) também é alto. .

BACKGROUND: Sunlight exposure is responsible for a large number of dermatological diseases. OBJECTIVE: We estimated the prevalence of sunlight exposure and its associated factors in adults from southern Brazil in a cross-sectional, population-based study. METHODS: We investigated a representative sample of individuals aged ≥ 20 years (n=3,136). Sunlight exposure and its associated factors were evaluated in two distinct situations: at leisure time and at work. The time period investigated ranged from December 2004 to March 2005, comprising 120 days of the highest ultraviolet index in the urban area of the city of Pelotas, in southern Brazil. The participants were asked about sunlight exposure for at least 20 minutes between 10 A.M. and 4 P.M. The analysis was stratified by sex, and sunlight exposure was grouped into five categories. RESULTS: Among the 3,136 participants, prevalence of sunlight exposure at the beach was 32.8% (95% CI, 30.3 - 35.2) and 26.3% (95% CI, 24.2 28.3) among men and women, respectively. The prevalence at work was 39.8% (95% CI, 37.2 - 42.4) among men and 10.5% (95% CI, 9.1 - 12.0) among women. Age was inversely associated with sunlight exposure. Family income and achieved schooling were positively associated with sunlight exposure at leisure time and inversely associated with sunglight exposure at work. Self-reported skin color was not associated. Knowledge of any friend or relative who has been affected by skin cancer was positively ...

Facial miliary osteoma is characterized by the presence of multiple normochromic papules, affecting mainly middle-aged women, with a previous history of acne. A 39-year-old HIV positive female patient presented hardened papules which had appeared 3 years before, located on the malar region, glabella and mentum. Optical microscopy showed spherical bone formations in the dermis. Computerized tomography of the face revealed small calcifications on the surface consistent with bone formation. Multiple facial osteomas are rare as well as its association with HIV virus infection.

Os osteomas miliares da face são caracterizados por múltiplas pápulas normocrômicas na face, afetando, geralmente, mulheres de meia idade, com história pregressa de acne. Uma paciente de 39 anos, portadora do HIV, apresentou pápulas endurecidas, com 3 anos de evolução, localizadas na região malar, glabela e mento. A microscopia óptica demonstrou formações ósseas esféricas na derme. A tomografia computadorizada da face observou pequenas calcificações na superfície, compatíveis com formação óssea. Os osteomas múltiplos da face são raros assim como sua associação com a infecção pelo HIV.

O eritema elevatum diutinum é vasculite cutânea rara. Caracteriza-se por pápulas e nódulos eritêmato-acastanhados, que podem coalescer formando placas. A região extensora dos membros é a mais acometida, e lesões antigas apresentam aspecto xantomatoso. O exame histopatológico apresenta infiltrado neutrofílico perivascular com depósito dérmico de fibrina, edema endotelial e leucocitoclasia. Apresenta-se um caso de eritema elevatum diutinum sem doença secundária associada.

Erythema elevatum diutinum is a rare presentation of cutaneous vasculitis. Typical lesions are papules, plaques, and nodules that may coalesce and later turn to yellow-brown color. The extensor surface of the extremities is the most involved area and older lesions may present xanthomatous appearance. Light microscopy of acute lesions shows neutrophilic, perivascular infiltrate with dermal fibrin deposits, endothelial expansion, and leukocytoclasis. We present a case of erythema elevatum diutinum without associated disease.

OBJETIVO: Estudar a prevalência dos padrões de sibilância respiratória e suas associações com variáveis independentes. MÉTODOS: Coorte de nascidos vivos, 1993, Pelotas (RS); subamostra sistemática de 20 por cento da coorte original acompanhada aos 6 e 12 meses e 4 anos; aos 10-12 anos localizou-se 87,5 por cento da coorte original. Definição dos padrões: transitório: chiado até 4 anos e ausência de chiado aos 10-12 anos; persistente: chiado em todos acompanhamentos; início tardio: chiado aos 10-12 anos. Variáveis independentes: gênero; cor da pele; renda familiar; fumo/asma na gravidez; amamentação; infecção respiratória/diarréia (1º ano); alergia e asma na família (4 e 10-12 anos); diagnóstico médico de rinite/eczema (10-12 anos). RESULTADOS: O total da subamostra foi de 897 adolescentes. Prevalência (IC95 por cento) dos padrões de sibilância: transitório 43,9 por cento (40,7-47,2);persistente 6,4 por cento (4,8-8,0); de início tardio 3,3 por cento (2,2-4,5). O transitório foi mais freqüente em crianças de famílias de baixa renda, com menor duração da amamentação, relato de infecções respiratórias (1º ano) e história familiar de asma (4 anos); o persistente foi quase duas vezes mais freqüente em meninos, em filhos de mulheres com asma na gravidez, com infecções respiratórias (1º ano) e história familiar de asma (4 e 10-12 anos); de início tardio mostrou maior prevalência naqueles com asma na família (10-12 anos) e diagnóstico médico de rinite (10-12 anos); menor prevalência em quem relatou infecções respiratórias (1º ano) e diagnóstico médico de eczema (10-12 anos). CONCLUSÕES: O conhecimento das associações dos padrões sibilantes permite a adoção de medidas preventivas e terapêuticas.

OBJECTIVE: To study the prevalence of wheezing patterns and their associations with independent variables. METHODS: Cohort study of live births in 1993 in Pelotas, Brazil. A systematic subsample (20 percent) of the original cohort was evaluated at 6 months, 12 months and 4 years. At 10-12 years, 87.5 percent of the original cohort was contacted. Wheezing was categorized: transient, wheezing at 4 years but not at 10-12; persistent, wheezing at all evaluations; late-onset, wheezing at 10-12 years. Independent variables were analyzed: gender; skin color; family income; smoking/asthma during pregnancy; breastfeeding; respiratory infection/diarrhea (during the 1st year); family members with asthma/allergy (at 4 years and at 10-12); physician-diagnosed rhinitis/eczema (at 10-12 years). RESULTS: The subsample comprised 897 adolescents. Wheezing patterns were expressed as prevalence (95 percent CI): transient, 43.9 percent (40.7-47.2); persistent, 6.4 percent (4.8-8.0); and late-onset, 3.3 percent (2.2-4.5). The transient pattern was more common in children from low-income families, children breastfed for less time, children with a history of respiratory infections (during the 1st year) and children with asthma in the family (at 4 years). The persistent pattern was almost twice as common in males, in children whose mothers had asthma during pregnancy, in children with respiratory infections (during the 1st year) and in children with asthma in the family (at 4 and 10-12 years). The late-onset pattern was more prevalent among those with asthma in the family (at 10-12 years) and those diagnosed with rhinitis (at 10-12 years), being less prevalent among those reporting respiratory infections (during the 1st year) and those diagnosed with eczema (at 10-12 years). CONCLUSIONS: Knowledge of the associations of wheezing patterns allows us to adopt preventive and therapeutic measures.

O objetivo deste estudo foi descrever e comparar as pregas cutâneas triciptal (PCT) e subescapular (PCS) de acordo com características demográficas, sócio-econômicas, comportamentais e biológicas em adolescentes de Pelotas, Rio Grande do Sul, Brasil. Realizou-se um estudo transversal aninhado a uma coorte de nascimentos (N = 4.452; média de idade = 11 anos). Os desfechos foram apresentar prega cutânea maior ou igual ao percentil 90 da curva de referência do National Center for Health Statistics. A prevalência de PCT e PCS elevada foi, respectivamente, de 20,2 por cento e 17,3 por cento nos meninos e de 14,2 por cento e 10,5 por cento nas meninas. O fator mais fortemente associado com adiposidade nos meninos foi o nível econômico (p < 0,001) e entre as meninas foi o índice de massa corporal materno (p < 0,001). Baixo nível de atividade física (< 300 minutos/semana) esteve associado com PCS elevadas somente entre as meninas, enquanto que escolaridade se associou à PCT e PCS elevada somente entre os meninos. Dieta, cor da pele e comportamento sedentário não se associaram com nenhum dos desfechos. Concluiu-se que os principais preditores de adiposidade foram características maternas e sócio-econômicas. Recomendam-se investigações utilizando-se outras técnicas de composição corporal para confirmação dos achados deste estudo.

The objective of this study was to describe and compare the tricipital (TSF) and subscapular skinfold (SSF) thickness according to demographic, socioeconomic, behavioral, and biological characteristics in adolescents from Pelotas, Rio Grande do Sul State, Brazil. A cross-sectional study nested in a birth cohort (n = 4,452; mean age = 11 years) was conducted. The outcomes were defined as skinfold thickness > 90th percentile of the National Center for Health Statistics reference curve. The prevalence rates for elevated TSF and SSF were 20.2 percent and 17.3 percent, respectively, in boys and 14.2 percent and 10.5 percent in girls. The strongest factor associated with adiposity in boys was socioeconomic status (p < 0.001), whereas among girls it was maternal body mass index (p < 0.001). Low physical activity (< 300 minutes/week) was associated with elevated SSF only among girls, while schooling was associated with increased TSF and SSF only among boys. Diet, skin color, and sedentary behavior were not associated with any of the outcomes. We concluded that the main predictors of adiposity were maternal and socioeconomic characteristics. We recommend that further studies on this issue apply other methods to estimate body composition in order to confirm our results.
