- Alergia a Medicamentos Reportada em Crianças que Frequentam InfantáriosPublication . Carreiro-Martins, P; Belo, J; Marques, J; Papoila, AL; Caires, I; Araújo-Martins, J; Pedro, C; Rosado-Pinto, J; Virella, D; Leiria-Pinto, P; Neuparth, NIntrodução: A prevalência de alergia a fármacos na população geral não se encontra devidamente caraterizada, existindo poucos estudos publicados que tenham abordado esta situação em crianças com idades inferior a seis anos de idade. Este estudo tem como objetivo principal estimar a prevalência de alergia a medicamentos reportada pelos pais de crianças de infantários de Lisboa e do Porto. Material e Métodos: No âmbito da Fase II do projeto “ENVIRH – Ambiente e Saúde em Creches e Infantários” foi aplicado um questionário sobre alergia a medicamentos aos pais das crianças, recrutadas por amostragem aleatória estratificada dos infantários. Resultados: Foram analisados 1 169 questionários, 52,5% de rapazes. A idade média foi de 3,5 ± 1,5 anos. A prevalência de alergia a medicamentos reportada foi de 4,1% (IC 95%: 3,0 - 5,2%). Os fármacos mais referidos foram os antibióticos (em 27 reações) e os AINEs (em seis reações). Na análise multivariável, a alergia a medicamentos reportada associou-se diretamente com a idade da criança (OR 1,19; IC 95% 1,01 - 1,41) e com a referência a alergia alimentar (OR 3,19; IC95% 1,41 - 7,19) e inversamente com o nível de escolaridade dos pais (OR 0,25; IC95% 0,10 - 0,59). Discussão: Apesar das limitações do estudo, os resultados encontram-se de acordo com o reportado por outros autores e sugerem que a prevalência reportada de alergia a medicamentos seja elevada no grupo etário estudado. Conclusão: Torna-se necessário que situações de alergia a medicamentos reportadas pelos pais sejam devidamente estudadas, no sentido de evitar evicções desnecessárias que possam condicionar opções terapêuticas em futuras situações de doença.
- Chronic Respiratory Diseases and Quality of Life in Elderly Nursing Home ResidentsPublication . Carreiro-Martins, P; Gomes-Belo, J; Papoila, AL; Caires, I; Palmeiro, T; Gaspar-Marques, J; Leiria-Pinto, P; Mendes, AS; Paulo-Teixeira, J; Botelho, MA; Neuparth, NFew studies have assessed the quality of life (QOL) related to chronic respiratory diseases in the elderly. In the framework of the geriatric study on the health effects of air quality in elderly care centers (GERIA) study, a questionnaire was completed by elderly subjects from 53 selected nursing homes. It included various sections in order to assess respiratory complaints, QOL (World Health Organization QOL (WHOQOL)-BREF), and the cognitive and depression status. The outcome variables were the presence of a score lower than 50 (<50) in each of the WHOQOL-BREF domains (physical health, psychological health, social relationships, and environmental health). Chronic bronchitis, frequent cough, current wheezing, asthma, and allergic rhinitis were considered as potential risk factors. The surveyed sample was (n = 887) 79% female, with a mean age of 84 years (SD: 7 years). In the multivariable analysis, a score of <50 in the physical domain was associated with wheezing in the previous 12 months (odds ratio (OR): 2.03, confidence interval (CI): 1.25-3.31) and asthma (OR: 1.95, CI: 1.12-3.38). The psychological domain was related with a frequent cough (OR: 1.43, CI: 0.95-2.91). A score of <50 in the environmental domain was associated with chronic bronchitis (OR: 2.89, CI: 1.34-6.23) and emphysema (OR: 3.89, CI: 1.27-11.88). In view of these findings, the presence of respiratory diseases seems to be an important risk factor for a low QOL among elderly nursing home residents.
- CO2 Concentration in Day Care Centres is Related to Wheezing in Attending ChildrenPublication . Carreiro-Martins, P; Viegas, J; Papoila, AL; Aelenei, D; Caires, I; Araújo-Martins, J; Gaspar-Marques, J; Cano, MM; Mendes, AS; Virella, D; Rosado-Pinto, J; Leiria-Pinto, P; Annesi-Maesano, I; Neuparth, NPoor ventilation at day care centres (DCCs) was already reported, although its effects on attending children are not clear. This study aimed to evaluate the association between wheezing in children and indoor CO2 (a ventilation surrogate marker) in DCC and to identify behaviours and building characteristics potentially related to CO2. In phase I, 45 DCCs from Lisbon and Oporto (Portugal) were selected through a proportional stratified random sampling. In phase II, 3 months later, 19 DCCs were further reassessed after cluster analysis for the greatest difference comparison. In both phases, children’s respiratory health was assessed by ISAAC-derived questionnaires. Indoor CO2 concentrations and building characteristics of the DCC were evaluated in both phases, using complementary methods. Mixed effect models were used to analyze the data. In phase I, which included 3,186 children (mean age 3.1±1.5 years), indoor CO2 concentration in the DCC rooms was associated with reported wheezing in the past 12months (27.5 %) (adjusted odds ratio (OR) for each increase of 200 ppm 1.04, 95 % CI 1:01 to 1:07). In phase II, the association in the subsample of 1,196 children seen in 19 out of the initial 45 DCCs was not significant (adjusted OR 1.02, 95 % CI 0.96 to 1.08). Indoor CO2 concentration was inversely associated with the practices of opening Windows and internal doors and with higher wind velocity. A positive trend was observed between CO2 and prevalence of reported asthma (4.7 %). Conclusion: Improved ventilation is needed to achieve a healthier indoor environment in DCC.
- Efeito Conjunto da Exposição à Poluição do Ar e aos Ácaros do Pó Sobre as Vias AéreasPublication . Carreiro-Martins, P; Valente, J; Papoila, AL; Caires, I; Araújo-Martins, J; Mata, P; Lopes, M; Simões Torres; Rosado-Pinto, J; Borrego, C; Neuparth, NIntrodução: A asma é uma doença respiratória crónica, cujo agravamento pode estar associado a factores ambientais, entre os quais os relacionados com a qualidade do ar. Objectivo: O presente trabalho pretendeu avaliar o efeito da exposição individual a poluentes atmosféricos em termos de função respiratória, num grupo de crianças com história de sibilância, entrando em consideração com o grau de infestação de ácaros do pó doméstico. Métodos: Um grupo de 51 crianças com história de sibilância, seleccionadas através do questionário do estudo ISAAC, foi acompanhado prospectivamente num estudo com medidas repetidas, que envolveu avaliações médicas padronizadas que incluíram a realização de espirometria, avaliação da exposição aos ácaros do pó e cálculo do valor de exposição individual a uma variedade de poluentes do ar: PM10, O3, NO2, benzeno, tolueno, xileno, etilbenzeno e formaldeído. Resultados: Observou -se uma elevada percentagem de colchões com um grau de infestação de ácaros médio ou elevado. Com excepção dos valores de PM10, os valores de exposição aos poluentes do ar não alcançaram valores elevados. Na análise multivariável, tanto os poluentes (designadamente PM10, NO2, benzeno, tolueno e etilbenzeno) como o grau de infestação de ácaros do pó associaram -se a deterioração da função pulmonar. Conclusão: O presente trabalho vem reforçar o interesse da exposição aos poluentes do ar em crianças com história de sibilância, que à semelhança do que acontece com os ácaros do pó influenciam as vias aéreas.
- Effect of Indoor Air Quality of Day Care Centers in Children with Different Predisposition for AsthmaPublication . Carreiro-Martins, P; Papoila, AL; Caires, I; Azevedo, S; Cano, MM; Virella, D; Leiria-Pinto, P; Teixeira, JP; Rosado-Pinto, J; Annesi-Maesano, I; Neuparth, NScarce information is available about the relationships between indoor air quality (IAQ) at day care centers (DCC), the estimated predisposition for asthma, and the actual wheezing susceptibility. METHODS: In the Phase II of ENVIRH study, 19 DCC were recruited after cluster analysis. Children were evaluated firstly using the ISAAC questionnaire and later by a follow-up questionnaire about recent wheezing. A positive asthma predictive index (API) was considered as predisposition for asthma. Every DCC was audited for IAQ and monitored for chemical and biologic contaminants. RESULTS: We included 1191 children, with a median age of 43 (P25 -P75 : 25-58) months. Considering the overall sample, in the first questionnaire, associations were found between CO2 concentration (increments of 200 ppm) and diagnosis of asthma (OR: 1.10; 95% CI: 1.00-1.20). Each increment of 100 μg/m(3) of total volatile organic compounds (TVOC) and 1 μg of Der p1/g of dust were associated with wheezing in the previous 12 months (OR: 1.06; 95% CI: 1.01-1.11 and OR: 1.06; 95% CI: 0.99-1.12, respectively). In the follow-up questionnaire, TVOC were again associated with wheezing (OR: 1.05; 95% CI: 1.00-1.11). Children exposed to fungal concentration above the 75th percentile had also higher odds of wheezing at follow-up. TVOC were associated with wheezing in children with either negative or positive API.
- Effect of Indoor Air Quality of Day Care Centers in children with Different Predisposition for SsthmaPublication . Carreiro-Martins, P; Papoila, AL; Caires, I; Azevedo, S; Cano, MM; Virella, D; Leiria-Pinto, P; Teixeira, JP; Rosado-Pinto, J; Annesi-Maesano, I; Neuparth, NBACKGROUND: Scarce information is available about the relationships between indoor air quality (IAQ) at day care centers (DCC), the estimated predisposition for asthma, and the actual wheezing susceptibility.

Children exposed to fungal concentration above the 75th percentile had also higher odds of wheezing at follow-up. TVOC were associated with wheezing in children with either negative or positive API. CONCLUSIONS: IAQ in DCC seems to be associated with wheezing, in children with and without predisposition for asthma.
- Food Allergy and Anaphylaxis in Infants and Preschool-Age ChildrenPublication . Gaspar-Marques, J; Carreiro-Martins, P; Papoila, AL; Caires, I; Pedro, C; Araújo-Martins, J; Virella, D; Rosado-Pinto, J; Leiria-Pinto, P; Neuparth, NFood allergy (FA) prevalence data in infants and preschool-age children are sparse, and proposed risk factors lack confirmation. In this study, 19 children’s day care centers (DCC) from 2 main Portuguese cities were selected after stratification and cluster analysis. An ISAAC’s (International Study of Asthma and Allergies in Childhood) derived health questionnaire was applied to a sample of children attending DCCs. Outcomes were FA parental report and anaphylaxis. Logistic regression was used to explore potential risk factors for reported FA. From the 2228 distributed questionnaires, 1217 were included in the analysis (54.6%). Children’s median age was 3.5 years, and 10.8% were described as ever having had FA. Current FA was reported in 5.7%. Three (0.2%) reports compatible with anaphylaxis were identified. Reported parental history of FA, personal history of atopic dermatitis, and preterm birth increased the odds for reported current FA. A high prevalence of parental-perceived FA in preschool-age children was identified. Risk factor identification may enhance better prevention.
- Improving Influenza Surveillance in Portuguese Preschool Children by Parents' ReportPublication . Paixão, P; Piedade, C; Papoila, AL; Caires, I; Pedro, C; Santos, M; Silvestre, MJ; Brum, L; Nunes, B; Guiomar, R; Curran, M; Carvalho, A; Marques, T; Neuparth, NInfluenza surveillance is usually based on nationally organized sentinel networks of physicians and on hospital reports. This study aimed to test a different report system, based on parents' phone contact to the research team and in home collection of samples by a dedicated team. The identification of influenza and other respiratory viruses in children who attended a Hospital Emergency Department was also recorded. Real-time PCR and reverse transcription PCR were performed for influenza A and B, parainfluenza 1-4, adenovirus, human metapneumovirus, respiratory syncytial virus A and B, rhinovirus, enterovirus, group 1 coronaviruses, group 2 coronaviruses, and human bocavirus. One hundred children were included, 64 from the day care centers and 36 from the Hospital. Overall, 79 samples were positive for at least one respiratory virus. Influenza A (H3) was the virus most frequently detected: 25 cases, 20 of these in children under 5 years of age (ten from day care centers and ten who went to the hospital) which was higher than those reported by the National Influenza Surveillance Programme for this age. CONCLUSION: The results obtained in this study suggest that a surveillance system based on parents' reports could complement the implanted system of the National Influenza Surveillance Programme.
- Medição do Óxido Nítrico no Ar Exalado: Utilização na Avaliação de Crianças com História de SibilânciaPublication . Carreiro-Martins, P; Caires, I; Rosado-Pinto, J; Lopes Mata, P; Torres, S; Valente, J; Borrego, C; Neuparth, NEncontram -se publicados múltiplos trabalhos sobre o papel das determinações do óxido nítrico no ar exalado (FENO) no âmbito do estudo da inflamação brônquica que nos permitem afirmar que se trata duma medição simples, não invasiva e de grande utilidade na avaliação do doente asmático.No decurso de um estudo prospectivo sobre o impacto da poluição do ar sobre a saúde da população na cidade de Viseu (Projecto Saud’AR), foram identificadas crianças com história clínica de sibilância, mediante a aplicação de questionários do International Study of Asthma and Allergy in Childhood (ISAAC). As crianças foram submetidas posteriormente a um questionário padronizado, testes cutâneos prick para aeroalergénios, espirometria com prova de broncodilatação e medição de FENO. A idade média era de 7,8±1,1 anos. Comparando os doentes com queixas de sibilância e/ou dispneia nos 6 meses anteriores à avaliação (n=27) com os que não apresentaram estes sintomas, observaram-se diferenças estatisticamente significativas para o ΔFEV1 (mediana: 4,5% vs 8%, p=0,0399) e para o FENO (mediana: 12 ppb vs 23 ppb, p=0,0195, respectivamente). Se olharmos para as crianças que recorreram a broncodilatador nos seis meses anteriores à avaliação (n=19) e as compararmos com as que não necessitaram, encontramos diferenças para o FENO: mediana de 27 ppb versus mediana de 11 ppb, respectivamente; p<0,0001. Ao compararmos as crianças que recorreram a uma consulta de urgência nos seis meses anteriores à avaliação(n=9) e as compararmos com as que não recorreram, encontramos também diferenças estatisticamente significativas para o FENO: mediana de 28 ppb versus mediana de 13 ppb, p=0.0029. Constatou -se assim que a existência de sintomas se associou melhor com o FENO de que com a espirometria.
- Reference Values for Spirometry in Elderly Individuals: a Cross-Sectional Study of Different Reference EquationsPublication . Belo, J; Palmeiro, T; Caires, I; Papoila, AL; Alves, M; Carreiro-Martins, P; Botelho, MA; Neuparth, NSpirometry is the single most important test for the evaluation of respiratory function. The results are interpreted by comparing measured data with predicted values previously obtained from a reference population. Reference equations for spirometry have been discussed previously. The aim of this study was to compare reference values based on National Health and Nutrition Assessment Survey (NHANES III), European Community of Steel and Coal (ECSC), and Global Lung Initiative (GLI) equations in an elderly sample population.
