Dermatitis atópica en niños y adolescentes asistidos en un hospital general de la Ciudad Autónoma de Buenos Aires / Atopic dermatitis in children and adolescents seen at a general hospital in the City of Buenos Aires

La dermatitis atópica (DA) es una enfermedad inflamatoria de la piel de alta prevalencia en pediatría, de acuerdo a estudios internacionales. Existe escasa información sobre las características epidemiológicas en la población pediátrica Argentina. El objetivo fue describir la prevalencia y características clínicas de la DA en una población de niños argentinos atendidos en el servicio de pediatría de un hospital general. Estudio observacional, de corte transversal. Se incluyeron 500 pacientes al azar, media de edad de 10 años (DE 5), el 50 % (250) de sexo femenino, de los cuales 24 presentaron DA. La prevalencia global fue del 5 % (IC95 % 3-7) y 3/24 fueron formas graves. La comorbilidad atópica más frecuente fue asma. La DA es una enfermedad con una prevalencia en nuestra población similar a la de otros países. Nuestro estudio aporta nuevos datos acerca de las características epidemiológicas de la dermatitis atópica en nuestra región

Atopic dermatitis (AD) is an inflammatory skin disease highly prevalent in pediatrics as per international studies. There is scarce information on the epidemiological characteristics of AD in the Argentine pediatric population. The objective of this study was to describe the prevalence and clinical characteristics of AD in a population of Argentine children seen at the Department of Pediatrics of a general hospital. Observational, cross-sectional study. Five hundred patients were randomly included; their mean age was 10 years (SD: 5); 50% (250) were female. A total of 24 had AD. The overall prevalence was 5% (95% confidence interval: 3­7) and 3/24 were severe forms. The most frequent atopic comorbidity was asthma. The prevalence of AD in our population is similar to that of other countries. Our study provides new data on the epidemiological characteristics of AD in our region.

Epidemiology and healthcare resource utilization in atopic dermatitis in Colombia: A retrospective analysis of data from the National Health Registry from 2015 to 2020 / Epidemiología y uso de recursos de salud en dermatitis atópica en Colombia: análisis retrospectivo de datos del Registro Nacional de Salud de 2015 a 2020

Introduction: Atopic dermatitis, also known as eczema or atopic eczema, is a chronic inflammatory skin disorder characterized by the presence of pruritus accompanied by itching. In Colombia, epidemiological and healthcare resource utilization information regarding this pathology is limited. Objective: To describe atopic dermatitis epidemiological characteristics and healthcare resource utilization patterns in Colombia. Materials and methods: A retrospective database study using real-world data obtained from the national claims database SISPRO (Sistema de Información para la Protección Social) for the 2015-2020 period was carried out. Sociodemographic (age, and health services delivery), epidemiological (incidence, prevalence, and comorbidities), and healthcare resource utilization data were extracted from the SISPRO database. Results: The epidemiological results showed increased incidence and prevalence of atopic dermatitis in Colombia in the 2018-2019 period compared to 2015-2017. Accordingly, the number of medical consultations (particularly with specialists), the number of procedures, and the number of hospitalizations of patients with atopic dermatitis increased. Topic and systemic corticoids were the most frequently prescribed drugs. Conclusions: Diagnoses of atopic dermatitis in Colombia increased with a concomitant increase in healthcare resource utilization during 2015-2020, which was possibly slowed down by the arrival of the Covid-19. This study may help physicians gaining a better understanding of the disease, improving atopic dermatitis patient management.

Introducción. La dermatitis atópica, también conocida como eczema o eczema atópico, es un trastorno inflamatorio crónico de la piel caracterizado por la presencia de prurito acompañado de picor. En Colombia, la información epidemiológica y de utilización de recursos sanitarios sobre esta enfermedad es limitada. Objetivo. Describir las características epidemiológicas y los patrones de utilización de recursos sanitarios para la dermatitis atópica en Colombia. Materiales y métodos. Se trata de un estudio retrospectivo en el cual se utilizan datos de la práctica clínica real obtenidos del registro nacional SISPRO (Sistema de Información para la Protección Social) en el período 2015-2020. Se extrajeron datos sociodemográficos (incluida la edad y la prestación de servicios de salud), epidemiológicos (incluidos la incidencia, la prevalencia y las comorbilidades) y los correspondientes a la utilización de los recursos sanitarios. Resultados. Los resultados epidemiológicos han demostrado un aumento de la incidencia y prevalencia de la dermatitis atópica en Colombia en el periodo 20182019, en comparación con el periodo 2015-2017. Aumentó el número de consultas médicas (particularmente, con especialistas) de pacientes con dermatitis atópica, el de procedimientos y el de hospitalizaciones. Los corticoides tópicos y sistémicos fueron los medicamentos más prescritos. Conclusiones. Los diagnósticos de dermatitis atópica en Colombia aumentaron con un incremento concomitante en la utilización de recursos sanitarios durante 2015-2020, que posiblemente se vio atenuado por la llegada del Covid-19. Este estudio puede ayudar a los médicos a tener un mejor conocimiento de la enfermedad y, por lo tanto, mejorar el tratamiento de los pacientes con dermatitis atópica.

Dermatite atópica em crianças e adolescentes durante a pandemia COVID-19: piora clínica associada ao medo de infecção / Atopic dermatitis in children and adolescents during the COVID-19 pandemic: disease exacerbation associated with fear of infection

Introdução: A dermatite atópica é uma doença crônica e recidivante, influenciada por fatores ambientais, que necessita prescrições médicas frequentes. O objetivo deste estudo foi investigar se crianças e adolescentes com dermatite atópica atendidos em um serviço público tiveram agravamento das lesões ou dificuldades no autocuidado durante a pandemia COVID-19.Métodos: Estudo longitudinal retrospectivo. Os dados foram coletados do prontuário de pacientes com dermatite atópica menores de 18 anos atendidos em um ambulatório público de referência do Rio Grande do Sul. A percepção sobre o agravamento das lesões foi avaliada pelos testes Qui-quadrado ou Exato de Fisher e regressão de Poisson foi utilizada para estimar o risco de agravamento das lesões conforme o medo da COVID-19.Resultados: Foram avaliados 33 pacientes, sendo 70% do sexo feminino e 57,6% residentes na capital. A média de idade foi de 9,6 ± 3,9 anos e o tempo médio de acompanhamento pelo serviço 4,6 ± 2,9 anos. A percepção de agravamento das lesões durante o período de suspensão dos atendimentos esteve presente em 81,8% das crianças/adolescentes. As crianças relataram com frequência o aumento de coceira (78,3%) e descamação (60,9%), enquanto os adolescentes referiram maior aumento da vermelhidão (60%). O medo de contrair o vírus foi associado a um risco oito vezes maior de apresentar agravamento das lesões.Conclusões: O alto percentual de crianças/adolescentes com agravamento das lesões e a associação da piora da doença com o medo relacionado à pandemia reforçam a importância do acompanhamento destes por equipe multidisciplinar que observe fatores fisiopatológicos e psicossociais.

Introduction: Atopic dermatitis is a chronic and recurrent condition, influenced by environmental factors, that requires frequent medical prescriptions. The aim of this study was to investigate if children and adolescents with atopic dermatitis treated at a public clinic reported exacerbation of the disease or self-care problems during the COVID-19 pandemic.Methods: We conducted a retrospective longitudinal study. Data were collected from the medical records of patients aged < 18 years with atopic dermatitis treated at a public outpatient clinic in Rio Grande do Sul, Brazil. The perception of disease exacerbation in children and adolescents was evaluated using the chi-square test or Fisher's exact test. Poisson regression was used to estimate the risk of worsening of skin lesions according to the fear of COVID-19. Results: The study sample included 33 patients, of whom 70% were female and 57.6% lived in the state's capital city. Mean patient age was 9.6 ± 3.9 years, and mean time of clinic follow-up was 4.6 ± 2.9 years. The perception of disease exacerbation during the pandemic was reported by 81.8% of children/adolescents. Children reported increased itching (78.3%) and desquamation (60.9%), whereas adolescents reported increased redness (60%). The fear of contracting COVID-19 was associated with an eight-fold increased risk of worsening of skin lesions.Conclusion: The high percentage of children/adolescents with worsening of skin lesions and the association between disease exacerbation and the fear of COVID-19 reinforce the importance of a multidisciplinary approach that focuses on pathophysiological and psychosocial factors in patients with atopic dermatitis.

Abstract | Introduction: Atopic dermatitis is a cutaneous, inflammatory, chronic disease, very frequent in the world and it imposes a high clinical and quality of life impact in patients. To date there are no local studies describing the general features in our population. Objective: To evaluate the socio demographic, clinical and life quality features in patients with atopic dermatitis from Medellín city and its metropolitan area. Materials and methods: cross sectional, descriptive study, that included patients who attended some teaching dermatological clinics. Data collection included sociodemographic and clinical features in addition to clinical issues and quality of life measurements. Results: A total of 13 patients were included. 36,3% manifested a sleeping disturbance, 38,1% attention deficit; 44,2% reported asthma in the childhood. EASI and SCORAD scores were 6,9 and 32,4, respectively, which indicates a mild-moderate compromise. Regarding quality of Life, Skindex-29 showed average scores for the symptomatic, emotional and functional dominions of 37,7, 25,09 and 16,9, respectively, and a total score of 24,78. In EQ-5D scores, the most altered component was the presence of pain or discomfort (17,6%) and the presence of anxiety or depression (12,1%), which enhances the symptomatic and emotional impact of the disease. Conclusion: These results confirm that patients with atopic dermatitis present similar features to those reported in other studies from different countries, highlighting the burden of the disease in adults and its impact in neuropsychiatric and emotional domains.

Pediatric dermatoses pattern at a Brazilian reference center

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

Asociación entre lactancia materna exclusiva y dermatitis atópica en un hospital de tercer nivel de atención / Association between exclusive breastfeeding and atopic dermatitis in a third level of care hospital

RESUMEN Objetivos. Evaluar si la lactancia materna exclusiva se asocia a la dermatitis atópica en niños menores de siete años. Materiales y métodos. Estudio tipo casos y controles no pareado, realizado en un hospital de tercer nivel de atención (Hospital Regional Lambayeque) entre junio de 2016 y mayo de 2018 en donde se evaluó 260 casos y 260 controles captados en consulta externa de los servicios de Dermatología y Pediatría. Se usaron los criterios del Reino Unido para el diagnóstico de dermatitis atópica y una encuesta con posibles factores de riesgo. Resultados. En el análisis bivariado se encontró diferencias entre los casos y controles en relación a lactancia materna exclusiva (p=0,001), antecedente familiar de atopia (p<0,001), nivel educativo de padres (p<0,001), hábito de fumar en presencia del niño (p=0,006) y procedencia (p=0,002). La lactancia materna exclusiva estuvo presente en 93 (35,8%) de los casos en comparación con 132 (50,8%) en los controles. En el análisis multivariado usando regresión logística se encontró que lactancia materna exclusiva tendría un efecto protector sobre la presencia de dermatitis atópica (OR= 0,62; IC95%= 0,41-0,94) ajustado por edad, sexo, procedencia, nivel educativo de los padres, inicio de alimentación complementaria, familiar con atopía y hábito de fumar. Conclusiones. La lactancia materna materna exclusiva tendría un efecto protector sobre la presencia de dermatitis atópica en niños menores de siete años.

ABSTRACT Objetive. To assess whether exclusive breastfeeding is associated with atopic dermatitis in children under seven years of age. Materials and Methods. Non-paired case and control type study conducted in a third level of care hospital (Lambayeque Regional Hospital) between June 2016 and May 2018 in which 260 cases and 260 controls recruited in outpatient consultation of the Dermatology and Pediatrics services were evaluated. The UK criteria were used for the diagnosis of atopic dermatitis, as well as a survey with possible risk factors. Results. In the bivariate analysis, differences were found between cases and controls in relation to exclusive breastfeeding (p=0.001), family history of atopy (p<0.001), parents' educational level (p<0.001), smoking in the presence of the child (p=0.006), and origin (p=0.002). Exclusive breastfeeding was present in 93 (35.8%) of cases compared to 132 (50.8%) of controls. The multivariate analysis using logistic regression found that exclusive breastfeeding would have a protective effect on the presence of atopic dermatitis (OR= 0.62; 95% CI= 0.41-0.94) adjusted by age, sex, background, parents' educational level, initiation of complementary feeding, family member with atopy, and smoking habit. Conclusions. Exclusive breastfeeding would have a protective effect on the appearance of atopic dermatitis in children under the age of seven.

INTRODUCTION: Erythroderma is an infrequent cutaneous inflammatory disorder characterized by generalized erythematous compromise and desquamation, of more than 90% of total cutaneous surface. OBJECTIVE: Clinical and histopathological cha-racterization of patients with erythroderma in a Chilean university hospital. METHODOLOGY: Retrospective study, performed at the University of Chile Clinical Hospital, based on review of clinical records and histopatho-logical reports of patients with erythroderma, between 2005 and 2018. Age, sex and clinical variables were evaluated (co-morbidities, symp-toms, days of evolution, hospital admission, histopathological report, diagnosis and evolu-tion). RESULTS: A total of 28 patients, 18 were men (64%), average age 59 years. Most frequent cause of erythroderma was pre-existing dermatosis, with 13 cases (52%), which included: psoriasis 9 (32%), contact dermatitis 3 (11%), PRP 2 (7%), atopic dermatitis 1 (4%). These are followed by adverse drug eruption 6 (21%), idiopathic 6 (21%) and Sezary syndrome 1 (4%). CONCLUSION: The present study corresponds to the first series of erythrodermas performed in Chile. The pre-existing dermatoses were the main cause of erythroderma, which coincides with other reports.

Aspectos de interés sobre la etiopatogenia de la dermatitis atópica / Interesting aspects about the etiopathogenesis of atopic dermatitis

La dermatitis atópica es una enfermedad inflamatoria crónica y su etiopatogénesis es multifactorial. La diversidad de factores de riesgo reportados en la bibliografía, evidencia la complejidad de las investigaciones con estos fines, y la interrelación entre ellos ofrece un problema para la orientación precisa en cada caso, al verse efectos que se superponen. El objetivo fue ofrecer una revisión actualizada sobre la etiopatogenia y fisiopatología de la dermatitis atópica que contribuya al incremento y actualización de la información sobre este tema. Se realizó una revisión en artículos de la base de datos PubMed y Scielo principalmente de los últimos 5 años y se sistematizan los resultados para de esta forma contribuir a la superación de los profesionales en la atención primaria de salud (AU).

The atopic dermatitis (DA by its acronym in Spanish) is a chronic inflammatory disease and its etiopathogenesis is multifactorial. The diversity of risk factors described in the bibliography evidences the complicatedness of the research with these aims and the interrelation among them offers a problem for the precise approach in each case, given the overlapped effects found. The aim is to give an up-dated review on atopic dermatitis etiopathogenesis and physiopathology helping to increase and up-date information on this topic. A review was carried out in articles appeared mainly in PubMed and Scielo databases during the last five years, and the results were systematized to contribute to the professional growth of health professionals working in the primary health care (AU).

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

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

Epidemiología de dermatosis pediátricas: experiencia de 30 años en Antofagasta, Chile / Epidemiology of pediatric dermatoses: experience of 30 years in Antofagasta, Chile

Introducción: La consulta por dermatología pediátrica es prevalente en dermatología general, por lo que estudiamos su importancia relativa y los motivos de consulta, en un periodo de 30 años en Antofagasta, Chile. Material y método: Se analizó el principal motivo de consulta en los menores de 15 años en una consulta dermatológica privada en 3 décadas, de 1984 a 2013. Se consideró diagnóstico, género, edad, previsión y se estudiaron las diferencias epidemiológicas entre las décadas en estudio. Resultados: El 26,6% de la consulta fue por dermatología pediátrica (15.742 pacientes). Los 10 principales motivos de consulta fueron prurigo insectario, dermatitis atópica, verrugas, escabiosis, impétigo, acné, estigmas atópicos, hemangioma, tiña y nevus melanocítico. Según décadas en estudio, la dermatitis atópica pasó del tercer al primer lugar en el periodo. Asimismo, disminuyeron escabiosis e impétigo y aumentaron acné y nevus melanocítico. Discusión: La dermatitis atópica ha llegado a ser el principal motivo de consulta dermatológica pediátrica en gran parte del mundo, especialmente en países desarrollados. Igualmente, la disminución de enfermedades bacterianas y parasitarias también es propia de países en desarrollo. Conclusiones: El volumen de consulta dermatológica pediátrica es importante, por lo que debe considerarse cuidadosamente en el currículo formativo del dermatólogo. Asimismo, los cambios epidemiológicos demostrados sugieren que nuestro país ha mutado a una epidemiología de país desarrollado.

Introduction: Consultation for pediatric dermatology is prevalent in general dermatology, that's why we studied the relative importance and motives of children's consultation in a period of 30 years in Antofagasta, Chile. Material and method: We analyzed the main motive of consultation in children under 15 years of age at a private dermatological clinic in 3 decades, from 1984 to 2013. Diagnosis, gender, age and social security system were considered and we studied the epidemiological differences between the decades in review. Results: 26,6% of the consultation was for pediatric dermatology (15.742 patients). The 10 main reasons for consultation were papular urticaria, atopic dermatitis, wart, scabies, impetigo, acne, atopic stigma, hemangioma, tinea and melanocytic nevus. According to decades under study, atopic dermatitis went from third to first place in the period. Likewise, scabies and impetigo diminished and acne and melanocytic nevus increased. Discussion: atopic dermatitis has become the main reason for pediatric dermatological consultation largely in the world, especially in developed countries. Similarly, the decline in bacterial and parasitic diseases is characteristic of developing countries. Conclusion: The volume of pediatric dermatological consultation is important, so it should be carefully considered in the training curriculum of the dermatologist. Likewise, the epidemiological changes demonstrated suggest that our country has mutated to a developed country epidemiology. Capsule Summary: Pediatric dermatology consultation is prevalent at a global level and atopic dermatitis is its main reason. In our investigation, both premises are fulfilled, important information that is partly extrapolable to guide public policies in dermatological formation and resource distribution.

Introducción. El efecto que tiene la lactancia materna y la alimentación complementaria sobre la prevalencia de las enfermedades alérgicas ha mostrado resultados inconsistentes. Objetivo. Evaluar el efecto de la lactancia materna y el momento de inicio de la alimentación complementaria en la prevalencia de las enfermedades alérgicas. Población y métodos. Estudio transversal analítico con base poblacional realizado en niños de 6 a 12 años de edad inscriptos en escuelas primarias, seleccionados mediante muestreo polietápico. Se aplicó a sus padres o tutores un cuestionario estructurado para identificar enfermedades alérgicas (asma, rinitis alérgica o dermatitis atópica), antecedente de lactancia materna prolongada y edad de inicio de la alimentación complementaria. La búsqueda de asociaciones entre variables se realizó mediante regresión logística. Resultados. Se incluyeron 740 niños. La frecuencia de lactancia e" 6 meses fue 73,4% y de alimentación complementaria con d" 4 meses fue 31,9%. La lactancia materna prolongada no tuvo efecto sobre la prevalencia de las enfermedades alérgicas. Se observó un efecto protector en la frecuencia de la dermatitis atópica cuando el inicio de la alimentación complementaria era tardío, OR ajustado= 0,36; IC95%: 0,1-0,8 (p 0,019). Conclusiones. El efecto protector de la lactancia materna sobre la prevalencia de las enfermedades alérgicas no pudo ser comprobado. La prevalencia de dermatitis atópica es menor con un comienzo tardío de la alimentación complementaria.

Introduction. The effect that breastfeeding and complementary feeding practices have on the prevalence of allergic diseases has shown inconsistent results. Objective. To assess the effect of breastfeeding and the initiation of complementary feeding on the prevalence of allergic disease. Population and Methods. Analytical, crosssectional population-based study conducted in 6-12 year old children attending primary school and selected through a multistage sampling technique. A structured questionnaire was administered to parents or tutors to identify allergic diseases (asthma, allergic rhinitis, or atopic dermatitis), a history of prolonged breastfeeding and age at initiation of complementary feeding. A logistic regression analysis was used to establish associations among variables. Results. A total of 740 children were included. The frequency of breastfeeding for >6 months was 73.4%, and of complementary feeding at <4 months old was 31.9%. Prolonged breastfeeding showed no effect on the prevalence of allergic diseases. A protective effect was observed on the frequency of atopic dermatitis when complementary feeding was initiated late, adjusted OR= 0.36, 95% confidence interval (CI): 0.1-0.8 (p 0.019). Conclusions. The protective effect ofbreastfeeding against the prevalence of allergic diseases has not been demonstrated. There is a reduction in the prevalence of atopic dermatitis when complementary feeding is started late.

Prevalence of asthma and allergic diseases in adolescents: nine-year follow-up study (2003-2012) / Prevalência de asma e doenças alérgicas em adolescentes: estudo evolutivo de nove anos (2003 a 2012)

OBJECTIVE: To determine the prevalence of symptoms of asthma, rhinitis, and atopic eczema in adolescents (AD; 13-14 years) living in seven Brazilian cities, by applying the standardized written questionnaire (WQ) of the International Study of Asthma and Allergies in Childhood (ISAAC), and to evaluate the time trend nine years after the last assessment of ISAAC phase 3 (ISP3). METHODS: The ISAAC-WQ was answered by 20,099 AD from the Northern, Northeastern, Southeastern, and Southern Brazilian regions. Values obtained were compared to those observed in ISP3 using nonparametric (chi-squared or Fisher) tests, and the ratio of annual increment/decrement was established for each of the centers, according to the symptom assessed. RESULTS: Considering the national data and comparing to values of ISP3, there was a decrease in the mean prevalence of active asthma (18.5% vs. 17.5%) and an increase in the frequency of severe asthma (4.5% vs. 4.7%) and physician-diagnosed asthma (14.3% vs. 17.6%). An increase in prevalence of rhinitis, rhinoconjunctivitis, and atopic eczema was also observed. CONCLUSIONS: The prevalence of asthma, rhinitis, and atopic eczema in Brazil was variable; higher prevalence values, especially of asthma and eczema, were observed in regions located closer to the Equator. .

OBJETIVO: Determinar a prevalência de sintomas relacionados à asma, à rinite e ao eczema atópico em adolescentes (13-14 anos, AD) residentes em sete cidades brasileiras com o questionário escrito (QE) padronizado do International Study of Asthma and Allergies in Childhood (Isaac) e verificar a tendência temporal passados nove anos da última avaliação do Isaac fase 3 (ISF3). MÉTODOS: O QE Isaac foi respondido por 20.099 AD (13-14 anos) moradores em centros das regiões Norte, Nordeste, Sudeste e Sul. Os índices obtidos foram comparados aos do ISF3 com o teste não paramétrico (qui-quadrado ou Fisher) e foi estabelecida a taxa de incremento/decremento anual para cada um dos centros segundo o sintoma avaliado. RESULTADOS: Em relação ao ISF3, considerando-se os dados nacionais, houve queda da prevalência média de asma ativa (18,5% vs. 17,5%) com elevação da frequência de asma grave (4,5% vs. 4,7%) e de asma diagnosticada por médico (14,3% vs. 17,6%). Aumento da prevalência de rinite e rinoconjuntivite e de eczema flexural também ocorreram. CONCLUSÕES: A prevalência de asma, rinite e eczema atópico no Brasil foi variável. Valores mais altos, sobretudo de asma e eczema, foram observados nos centros localizados mais próximos ao Equador. .

A 9-year Trend in the Prevalence of Allergic Disease Based on National Health Insurance Data / 예방의학회지

OBJECTIVES: To investigate trends in the prevalence of allergic disease over a 9-year period. METHODS: Using National Health Insurance Service (NHIS) data, the annual number of patients with allergic disease was obtained for each regional subdivisions (small cities, counties, and districts) from 2003 to 2011. Annual populations for each sub-region were obtained and used to calculate the standardized prevalence. To compare prevalence within the study period, data was standardized spatially and temporally. For standardization, demographic data was used to obtain the registered population and demographic structure for 2010, which was used to perform direct standardization of previous years. In addition, a geographic information system (GIS) was used to visualize prevalence for individual sub-regions, and allergic diseases were categorized into five groups according to prevalence. RESULTS: The nationwide outpatient prevalence of allergic rhinitis increased approximately 2.3-fold, from 1.27% in 2003 to 2.97% in 2013, while inpatient prevalence also increased approximately 2.4-fold,. The outpatient prevalence of asthma increased 1.2-fold, and inpatient prevalence increased 1.3-fold. The outpatient prevalence of atopic dermatitis decreased approximately 12%, and inpatient prevalence decreased 5%. CONCLUSIONS: There was a large difference between prevalence estimated from actual treatment data and prevalence based on patients' self-reported data, particularly for allergic rhinitis. Prevalence must continually be calculated and trends should be analyzed for the efficient management of allergic diseases. To this end, prevalence studies using NHIS claims data may be useful.

Factors Associated with Cataract in Korea: A Community Health Survey 2008-2012

PURPOSE: To investigate sociodemographic factors, health behaviors, and comorbidities associated with cataracts in a large, nationally representative Korean sample. MATERIALS AND METHODS: This cross-sectional study included 715554 adults aged 40 years or older who participated in the 2008-2012 Community Health Survey. Significant risk factors were identified using multivariate logistic regression analysis for self-reported cataract, and a nomogram for analysis of cataract risk was generated. RESULTS: Roughly 11% of participants (n=88464) reported being diagnosed with cataracts by a doctor. Age was the most important independent risk factor [adjusted odds ratio (aOR)=1.11, 99% confidence interval (CI), 1.11-1.11 for each increasing year]. Significant comorbidities with descending order of effect size (aOR, 99% CI), included diabetes mellitus (1.78, 1.71-1.85), osteoporosis (1.62, 1.56-1.69), arthritis (1.54, 1.48-1.59), hepatitis B infection (1.46, 1.31-1.63), atopic dermatitis (1.50, 1.33-1.69), angina (1.46, 1.35-1.57), allergic rhinitis (1.45, 1.36-1.55), dyslipidemia (1.38, 1.31-1.45), asthma (1.35, 1.26-1.44), and hypertension (1.23, 1.19-1.28). Subjects who sleep less than 6 hours/day were more likely to have cataract than subjects who sleep more than 9 hours/day as a reference group (aOR=1.22, 99% CI, 1.11-1.34). CONCLUSION: While the most important cataract risk factor was age, the ten comorbidities mentioned above were also significant risk factors. Interestingly, longer duration of sleep was associated with a protective effect against cataract development.

Methicillin-resistant Staphylococcus aureus colonization and disease severity in atopic dermatitis: A cross-sectional study from South India.

Background: Colonization by methicillin-resistant Staphylococcus aureus (MRSA) in atopic dermatitis is little studied but has therapeutic implications. It may have a role in disease severity given the additional virulence factors associated. Aims: Our aims were to record the proportion of patients with MRSA colonization in atopic dermatitis and to ascertain if any association exists between MRSA colonization and disease severity. Methods: An observational cross-sectional study involving children aged≤12 years with atopic dermatitis attending the outpatient department of Government Medical College, Kottayam was conducted. Socio-demographic data, exacerbating factors and risk factors for hospital care-associated MRSA were documented. Extent of atopic dermatitis was recorded using a standardized scale (Eczema Area Severity Index, EASI). Skin swabs were taken from anterior nares and the worst affected atopic dermatitis sites for culture and sensitivity. Results: Of the 119 subjects recruited during the study period (November 2009-April 2011), Staphylococcus aureus was isolated from 110 (92.4%) patients and MRSA from 30 (25.21%) patients. A total of 18 patients with MRSA had risk factors for healthcare associated-MRSA. The patients whose cultures grew MRSA were found to have significantly higher EASI score when compared to those patients colonized with methicillin sensitive Staphylococcus aureus (P < 0.01). Presence of Staphylococcus aureus, early age of onset, presence of food allergies, seasonal exacerbation and inadequate breastfeeding did not seem to influence disease severity. Conclusions: There is a high degree of prevalence of MRSA (25.2%) in atopic dermatitis and presence of MRSA is associated with increased disease severity. Further studies are needed to validate these findings.

Epidemiologia da alergia ocular e comorbidades em adolescentes / Epidemiology of ocular allergy and co-morbidities in adolescents

OBJETIVO: A prevalência de conjuntivite alérgica (CA) não foi estabelecida. Estimativas sugerem que alergias oculares afetam de 15 a 20% da população mundial, ainda que a maioria dos estudos epidemiológicos abranjam sintomas de alergia nasal e ocular e não sejam específicos a respeito da CA. O objetivo deste estudo foi verificar a prevalência de sintomas, comorbidades e o impacto da alergia ocular em adolescentes. MÉTODOS: Os adolescentes foram selecionados de uma amostra de escolas e preencheram, em sala de aula, um questionário previamente validado sobre os sintomas da CA. O seu diagnóstico foi considerado quando mais de três episódios de prurido ocular foram relatados nos últimos 12 meses. Sintomas relacionados, como lacrimejamento, fotofobia, sensação de corpo estranho, impacto sobre as atividades diárias e diagnóstico de conjuntivite alérgica, foram analisados. RESULTADOS: Foram obtidos questionários de 3.120 adolescentes (média de 13,3±1,1 ano). Nos últimos 12 meses, 1.592 (51%) adolescentes tiveram prurido ocular. O sintoma relacionado mais frequente foi lacrimejamento (74%), seguido de fotofobia (50,1%) e sensação de corpo estranho (37,1%). A prevalência de conjuntivite alérgica foi de 20,7%, afetando mais pessoas do sexo feminino do que do masculino (56,1% em comparação a 45,9%; p = 0,01). O risco de um adolescente com alergia ocular apresentar asma, rinite e eczema atópico foi (RC = 5,7; IC de 95%: 4,5 a 7,1); (RC = 3,6; IC de 95%: 3,0 a 4,3) e (RC = 2,6; IC de 95%: 2,0 a 3,5), respectivamente. Uma interferência grave nas atividades diárias foi relatada por 30,5%. CONCLUSÕES: Sintomas de alergia ocular são comuns, frequentemente relacionados a outras doenças alérgicas, e causam impacto sobre as atividades diárias de adolescentes.

OBJECTIVE: The prevalence of allergic conjunctivitis (AC) has not been established. Estimates suggest that ocular allergies affect 15% to 20% of the worldwide population, yet most epidemiological studies encompass nasal and ocular allergy symptoms and have not been specific to AC. The aim of this study was to verify the prevalence of ocular allergy symptoms, co-morbidities, and their impact on adolescents. METHODS: Adolescents were selected from a sample of schools, and completed in classrooms a previously validated questionnaire on symptoms of AC. AC diagnosis was considered when more than three episodes of ocular itching were reported in the past 12 months. Related symptoms such as tearing, photophobia, foreign body sensation, impact on daily activities, and diagnosis of AC were analyzed. RESULTS: Questionnaires were obtained from 3,120 adolescents (mean age 13.3 ± 1.1 years). Ocular itching in the past 12 months occurred in 1,592 (51%). The most frequently associated symptom was tearing (74%), followed by photophobia (50.1%) and foreign body sensation (37.1%). The prevalence of AC was 20.7%, affecting more females than males (56.1% versus 45.9%; p = 0.01). The risks of an adolescent with ocular allergy to present asthma, rhinitis, and atopic eczema were (OR = 5.7; 95% CI: 4.5 to 7.1), (OR = 3.6; 95% CI: 3.0 to 4.3), and (OR = 2.6; 95% CI: 2.0 to 3.5), respectively. Severe interference in daily activities was reported by 30.5%. CONCLUSIONS: Symptoms of ocular allergy are common, frequently associated to other allergic diseases, and impact the daily activities of adolescents.
