- 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.
- Factors Associated With Asthma Control in 121 Preschool ChildrenPublication . Leiria-Pinto, P; Carreiro-Martins, P; Peralta, I; Marques, J; Finelli, E; Alves, C; Belo, J; Alves, M; Papoila, AL; Neuparth, NBackground: Data on risk factors for uncontrolled asthma in preschool children are controversial. Objective: This study aims to explore the association between clinical and functional parameters and the lack of asthma control in preschool children. Methods: Children aged 3-5 years with asthma and healthy controls were recruited. A questionnaire was used to identify potential risk factors for uncontrolled asthma, as defined by the Global INitiative for Asthma criteria. Lung function and bronchial reversibility were evaluated through impulse oscillometry and spirometry. Adjusted odds ratios were estimated based on multivariable generalized additive regression models. The discriminative ability of the models was measured by the area under the receiver operating characteristic curve (AUC). Results: The study population comprised 121 children (107 with asthma and 14 healthy controls). Fifty-three patients (50%) had uncontrolled asthma. After adjustment, the variables associated with an increased risk of lack of control were as follows: “More than 3 flare-ups in the last 12 months”, “Moderate to severe rhinitis”, and “Relative variation in postbronchodilator FVC and FEV1”. The AUC of the final models that included variation in FVC or FEV1 were 0.82 and 0.81, respectively. The R5-20, R5-20%, and AX z-score values of the healthy group were lower than those of children with asthma. Conclusion: In preschool children, clinical and functional parameters are associated with uncontrolled asthma. More studies are needed to confirm the usefulness of impulse oscillometry.

- 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.
