BACKGROUND: Indoor allergens are risk factors for asthma: thus, the characterization of indoor air quality is important for studying environment-health relationships in children. In particular, Dermatophagoides pteronyssinus is the dominant allergen for asthma. We cross-sectionally investigated the relationships among respiratory symptoms and function, airway inflammation, allergen sensitization and indoor allergen concentration. METHODS: One hundred thirty two children aging 10-14 years and living in a Southern Mediterranean area were evaluated by parental questionnaires...

BACKGROUND: In children, exercise-induced dyspnea is a common symptom that can be due to dysfunctional breathing. EVH test has bee used especially in elite athletes as bronchoprovocation test. Currently, there are only few studies on the EVH test. New research methods are required alongside the traditionally used tests especially due to dysfunctional breathing disorder. PURPOSE: The purpose of the "pilot study" was to study the usability of the EVH test with real time biofeedback in children of 10-16 years of age in the diagnostics of exercise-induced dyspnea...

BACKGROUND: Obesity is increasing worldwide among children and adolescents, and has been associated with an increased incidence of asthma. However, the mechanisms underlying this association are incompletely understood. OBJECTIVE: In this cohort study we aimed to investigate whether being overweight in childhood and adolescence is associated with an increased risk of airway hyperresponsiveness (AHR), a hallmark of asthma, in early adulthood. METHODS: Of 527 subjects from a random population sample of children and adolescents (7-17 years) examined at baseline, a total of 184 subjects completed the follow-up visit 20 years later and were included in the present analysis...

BACKGROUND: Breath-actuated inhalers (BAI) eliminate the need for hand-breath coordination and, therefore, simplify thedelivery of inhaled medication. OBJECTIVE: To evaluate the efficacy and safety of beclomethasone dipropionate BAI and metered-dose inhaler (MDI) versus placebo in pediatric patients ages 4-11 years with persistent asthma. METHODS: In this double-blind, double-dummy, phase III study, 628 children with persistent asthma were randomly assigned(1:1:1:1:1) to twice-daily beclomethasone dipropionate (BAI 80 micrograms/day, BAI 160 micrograms/day, MDI 80 micrograms/day, or MDI 160 micrograms/day) or to placebo...

OBJECTIVES: American Thoracic Society/European Respiratory Society (ATS/ERS) spirometry interpretation guidelines recommend ≥15 min between pre- and post-bronchodilator testing to evaluate for a bronchodilator response. We aimed to lengthen the time between albuterol administration and post-bronchodilator testing to adhere to ATS/ERS guidelines and evaluated if lengthening this wait time would increase the percentage of patients classified as bronchodilator responsive. METHODS: We compared the proportion of patients with a positive bronchodilator response between two groups of children with asthma, one group in which post-bronchodilator administration wait times were not standardized (pre-intervention) to another in which the wait time was extended to 15 min to adhere to ATS/ERS standards (post-intervention)...

Theoretical non-linear modeling of exhaled nitric oxide has revealed extended flow-independent parameters that could explain where or how nitric oxide is produced in the lung and transferred to the airway gas stream. We aimed to evaluate the associations of bronchial hyperresponsiveness and bronchodilator response with extended flow-independent nitric oxide parameters. Nitric oxide (30, 50, 100, 200 mL/s) was measured in 432 children with asthma on the same day as either methacholine challenge test (n=156) or spirometry with bronchodilator (n=276; 96 previously diagnosed with asthma and treated with inhaled corticosteroid, 37 with acute exacerbation treated with systemic corticosteroid)...

Sport is an essential part of childhood, with precious and acknowledged positive health effects but the impact of exercise-induced bronchoconstriction (EIB) significantly reduces participation in physical activity. It is important to recognize EIB, differentiating EIB with or without asthma if the transient narrowing of the airways after exercise is associated with asthmatic symptoms or not, in the way to select the most appropriate treatment among the many treatment options available today. Therapy is prescribed based on symptoms severity but diagnosis of EIB is established by changes in lung function provoked by exercise evaluating by direct and indirect tests...

BACKGROUND: Breastfeeding reduces the risk of asthma in early childhood, but it is not clear whether its effect on respiratory morbidity is still present in later childhood. OBJECTIVE: To examine the associations of any breastfeeding, breastfeeding duration, and breastfeeding exclusiveness with lung function and asthma in school-aged children and whether associations were influenced by respiratory tract infections and maternal or child's atopic status. METHODS: This study of 4,464 children was embedded in a population-based prospective cohort study...

The forced oscillation technique (FOT) can provide unique and clinically relevant lung function information with little cooperation with subjects. However, FOT has higher variability than spirometry, possibly because strategies for quality control and reducing artifacts in FOT measurements have yet to be standardized or validated. Many quality control procedures either rely on simple statistical filters or subjective evaluation by a human operator. In this study, we propose an automated artifact removal approach based on the resistance against flow profile, applied to complete breaths...

BACKGROUND: We wanted to compare cold dry air challenge (CACh) induced changes in spirometric parameters with changes in nitrogen multiple breath washout (N2 MBW) parameters in pediatric asthma patients during clinical remission over the past year (ie, with "inactive asthma"). As N2 MBW assesses ventilation heterogeneity we expected to gain detailed information about peripheral airways contribution. METHODS: In subjects with normal spirometry N2 MBW, spirometry and body plethysmography were performed at baseline, after CACh, and after salbutamol inhalation...
