BACKGROUND Asthma is a frequent chronic respiratory disease in both children and adults. However, few data on asthma prevalence are available in Portugal. The Portuguese National Asthma Survey is the first nationwide study that uses standardized methods. We aimed to estimate the prevalence of current asthma in the Portuguese population and to assess the(More)
BACKGROUND The values obtained when the fraction of exhaled nitric oxide (FeNO) is measured are affected by several factors that are specific to the individual patient, making interpretation difficult, especially in the initial assessment of patients with respiratory symptoms. METHODS Systematic review of studies on FeNO reference values and(More)
BACKGROUND Fraction of exhaled nitric oxide (Feno) and blood eosinophil count (B-Eos) values, markers of local and systemic eosinophilic inflammation, respectively, are increased in asthmatic patients. Little is known about the relation of these markers to reported wheeze and asthma events in a random population sample. OBJECTIVES We sought to determine(More)
BACKGROUND Atopy and rhinitis are among the factors affecting exhaled nitric oxide (FeNO) values and may contribute to difficulties in the clinical interpretation of FeNO measurements. However, data assessing their effects on FeNO values had never been summarized. This review aims to evaluate the effect of atopy and rhinitis in FeNO values in otherwise(More)
OBJECTIVE The best combination of questions to define asthma in epidemiological asthma studies is not known. We summarized the operational definitions of asthma used in prevalence studies and empirically assess how asthma prevalence estimates vary depending on the definition used. METHODS We searched the Thomson Reuters ISI Web of knowledge and included(More)
Asthma frequently occurs in association with allergic rhinitis and a combined management approach has been suggested. The Control of Allergic Rhinitis and Asthma Test (CARAT) is the first questionnaire to assess control of both diseases concurrently. However, to have an impact on healthcare it needs to be disseminated and adopted. In this paper we discuss(More)
BACKGROUND Asthma and allergic rhinitis (ARA) are common inflammatory diseases of the airways. Enhancement of a patient's participation on clinical decisions is related to better results in control of diseases. To control ARA, patients should monitor their symptoms, avoid triggers, and follow their treatment plan. This study described the challenges of(More)
BACKGROUND Guided self-management is an important component of asthma care. Most trials have evaluated paper-based strategies. The effectiveness of new communication technologies remains uncertain. OBJECTIVES To compare the feasibility and clinical outcomes of a standard paper-based asthma self-management strategy with web-based strategies. METHODS In a(More)
