Abstract Background The severity of nail disease, the presence of arthralgia and fatigue are predictors of development of psoriatic arthritis (PsA) in patients with psoriasis (Pso). In children, little is known about the musculoskeletal (MSK) impairment in patients with Pso and its effect on health-related quality of life (HRQoL). Objectives To determine the frequencies of pain and MSK inflammation (i.e., arthritis, enthesitis, and sacroiliitis) among children and adolescents with Pso and its relationship to HRQoL and fatigue. Methods Pediatric patients with Pso underwent a rheumatologic physical examination to evaluate synovitis, enthesalgia, sacroiliac joint (SIJ) pain and tender points of fibromyalgia. The core set of domains recommended by the GRAPPA - OMERACT to be measured in PsA studies was assessed. Ultrasound (US) was performed in clinical cases of enthesitis, and magnetic resonance imaging (MRI) was performed in cases of SIJ pain. Results Forty-three participants (10 ± 2.9 years old) were evaluated. Pain on palpation of the entheses was observed in 10 (23.2%) patients and pain on SIJ palpation was observed in 3 (7%). No patient presented with synovitis; one presented with enthesitis on US, but MRI did not confirm sacroiliitis in any case. Patients with MSK pain had greater skin disease severity (PASI 5.4 vs. 2, p < 0.01), worse fatigue, and lower HRQoL scores on all instruments used. The estimated risk of HRQoL impairment was eight times higher in the presence of MSK pain, which was an independent predictive factor. With a NAPSI greater than 30, the probability of pain was greater than 80%. Conclusion MSK pain is frequent among children with Pso, related to the severity of skin and nail disease, and negatively affects HRQoL. The typically used complementary exams might not detect the inflammatory process caused by Pso.

RESUMO Objetivo: Avaliar os hábitos de higiene e a frequência do uso de produtos de higiene pessoal, cosméticos e protetor solar nas crianças e adolescentes. Métodos: Estudo transversal com entrevistas para cuidadores sobre cuidados com a pele, por meio de perguntas fechadas. Incluídos pacientes de até 14 anos que consultavam nos ambulatórios pediátricos de um hospital terciário. Realizada estatística descritiva e aplicados os testes de Kruskal-Wallis e exato de Fisher para comparar os hábitos conforme a escolaridade materna. Resultados: Foram realizadas 276 entrevistas. A mediana de idade foi de 4 anos, sendo 150 (54,3%) crianças do sexo masculino. O número de banhos por dia foi de um em 143 (51,8%) casos e dois ou mais por parte de 128 (46,3%) indivíduos, com duração de até dez minutos em 132 (47,8%) dos participantes. O sabonete destinado a adultos era utilizado por 103 (37,3%) crianças e o sabonete em barra por 220 (79,7%) delas. Protetor solar era utilizado diariamente por 53 (19,2%) participantes. Perfume foi utilizado por 182 (65,9%) integrantes da amostra, gel de cabelo por 98 (35,5%), esmalte por 62 (22,4%) e algum tipo de maquiagem por 71 (25,7%) - sombra em 30 (10,8%), batom em 52 (18,8%), pó facial e rímel em 13 (4,7%). A mediana de idade de início do uso de maquiagem foi de 4 anos. Tatuagem de hena foi realizada em oito crianças. Conclusões: As crianças estudadas utilizavam produtos inadequados para a sua pele, como os destinados à pele do adulto, e faziam uso incorreto do protetor solar e uso precoce de maquiagem, mostrando a importância da orientação médica.

ABSTRACT Objective: To evaluate the hygiene practices and frequency of use of personal hygiene products, cosmetics, and sunscreen among children and adolescents. Methods: Cross-sectional study with interviews about skincare conducted with caregivers through closed-ended questions. We included patients up to 14 years of age waiting for consultation in pediatric outpatient clinics of a tertiary hospital. We performed a descriptive statistical analysis and applied the Kruskal-Wallis test and Fisher’s exact test to compare the practices according to maternal schooling. Results: We conducted 276 interviews. The median age of the participants was age four, and 150 (54.3%) were males. A total of 143 (51.8%) participants bathed once a day and 128 (46.3%) bathed two or more times a day, lasting up to ten minutes in 132 (47.8%) cases. Adult soap was used by 103 (37.3%) children and bar soap by 220 (79.7%). Fifty-three (19.2%) participants used sunscreen daily. Perfume was used by 182 (65.9%) children, hair gel by 98 (35.5%), nail polish by 62 (22.4%), and some type of make-up by 71 (25.7%) - eyeshadow by 30 (10.8%), lipstick by 52 (18.8%), face powder and mascara by 13 (4.7%). Make-up use started at a median age of 4 years. Henna tattoo was done in eight children. Conclusions: The children studied used unsuitable products for their skin, such as those intended for adults, used sunscreen inadequately, and started wearing make-up early, evidencing the need for medical orientation.

Abstract: Background: The greatest sun exposure occurs until adolescence and this is the only factor involved in photocarcinogenesis subject to modification with photoprotection. Objective: The objective of this study was to evaluate the habits and knowledge of adolescents regarding photoprotection. Method: Cross-sectional study that included 512 students from primary and high school. Data were collected by questionnaires with questions about habits and knowledge on sun protection. For data analysis, Pearson's Chi-square test and Yates test were applied, with 5% level of significance. Results: We evaluated 512 students, with a mean age of 14 years old. The teenagers agreed that ultraviolet rays cause skin cancer and aging (96% and 70%, respectively). Knowledge about the occurrence of burns even on cloudy days was recorded in 68% of cases, as well as the need for photoprotection for sports in 72%. The source of information about sun protection were by parents in 55%. In 70% was observed previous occurrence of sunburn, the daily use of sunscreens was found in 15% and 67% used only at the beach. of sunscreens with SPF higher than 30 was reported by 70% of students and 57% reported going to the beach between 10h and 16h. In 68% of cases it was registered insufficient sun protection, attributed, in 57% of the time to forgetfulness. Study limitations: The sample refers to two schools of Curitiba (PR), Brazil. Conclusion: Teenagers know the risks of sun exposure, but they do not adopt the practices for adequate protection.

A paraqueratose granular é alteração da queratinização, primeiramente descrita em adultos, caracterizada por pápulas e placas hiperqueratósicas nas áreas intertriginosas. Os autores descrevem seis casos de paraqueratose granular em crianças. Um paciente apresentava lesões nas regiões glúteas, dois em ambas as axilas e região cervical (apresentações inéditas na literatura). Três pacientes apresentavam lesões em pregas inguinais. Realizam também revisão da literatura e discutem a possível etiologia dessa rara dermatose.

Granular parakeratosis is an alteration of keratinization that was first described in adults. It is characterized by hiperkeratotic plaques and papules in intertriginous areas. The authors describe six cases of granular parakeratosis in children. One patient had lesions on the buttocks; two children presented papules in both axillae and cervical region (presentations never described before in the literature). The remaining three patients presented with lesions in the inguinal folds. Review of the literature and discussion on the pathogenesis of this rare dermatosis are presented.

FUNDAMENTOS: Desde o início da epidemia da Aids as dermatoses têm sido freqüentemente descritas em pacientes com essa doença, com relatos de casos atípicos e estudos de séries de pacientes adultos; no entanto, há poucas publicações sobre alterações cutâneas em pacientes pediátricos com Aids. OBJETIVOS: Estudo prospectivo para avaliar a presença de dermatoses em 40 pacientes pediátricos com Aids. MÉTODOS: Quarenta pacientes, com idade inferior a 13 anos e portadores de Aids, foram estudados por um período de seis meses para avaliação de: número de alterações dermatológicas; suas características clínicas; distribuição conforme as categorias clínico-imunológicas e o valor da carga viral. RESULTADOS: A prevalência de dermatoses foi de 82,4%, na primeira consulta, e, no acompanhamento longitudinal, 92,5% dos pacientes tiveram alterações dermatológicas, com proporção de cinco diagnósticos por doente. As crianças com classificação clínico-imunológica grave e carga viral acima de 100.000 cópias/ml apresentaram maior número de alterações dermatológicas quando comparadas àquelas das categorias clínico-imunológicas leves. A proporção de diagnósticos por paciente na categoria clínica C foi de 6,8 e na A de 3,6; na categoria imunológica grave, de sete, e na leve de 3,7; e na carga viral > 100.000 de 7,3, e na < 100.000 de 4,2 (todos com significância estatística). CONCLUSÃO: As dermatoses foram freqüentes nas crianças com Aids e ocorreram em maior número nos pacientes pertencentes às categorias graves. A elevada freqüência de alterações da pele nos pacientes pediátricos com a doença indica ser imprescindível sua avaliação dermatológica minuciosa e freqüente.

BACKGROUND: Ever since the beginning of the Acquired Immunodeficiency Syndrome (Aids) epidemic, a number of dermatoses have been frequently described in patients with this disease. In the literature, case reports and studies in series of adult patients with atypical lesions are frequent found. By contrast, there are few reports on cutaneous alterations in pediatric patients with Aids. OBJECTIVE: The purpose of the following prospective survey is to evaluate the presence of dermatoses in 40 pediatric patients with Aids. METHOD: Forty patients diagnosed with Aids and less than 13 years of age were seen for six months. The following features were evaluated: number of dermatoses, clinical characteristics, distribution in accordance with the clinical-immunological categories in relation to CD4 T-lymphocyte and viral load values. RESULTS: The prevalence of dermatoses in the first evaluation was 82.4%. In a longitudinal follow-up, 92.5% of the patients developed some kind of skin problem. Children belonging to the worst clinical-immunological category, with a viral load higher than 100,000 copies/ml showed a higher number of dermatoses when compared to the mildest categories. The number of dermatologic alterations per patient was 6.8 in clinical category C and 3.6 in A. In the immunological severe category, it was 7.0, while in the mild one, it was 3.7. For viral load > 100,000, the number was 7.3, and for < 100,000, it was 4,2 (all with statistical significance). CONCLUSION: Dermatological alterations were frequent and directly related to advanced stages of Aids in pediatric patients. Higher frequencies of skin alterations in pediatric patients with Aids indicate that it is necessary to perform careful and frequent dermatological examinations of these patients.
