BACKGROUND: Exposure to airborne particles has a major impact on global health. The probability of these particles to deposit in the respiratory tract during breathing is essential for their toxic effects. Observations have shown that there is a substantial variability in deposition between subjects, not only due to respiratory diseases, but also among individuals with healthy lungs. The factors determining this variability are, however, not fully understood. METHOD: In this study we experimentally investigate factors that determine individual differences in the respiratory tract depositions of inhaled particles for healthy subjects at relaxed breathing...

BACKGROUND: The diagnosis and assessment of COPD rely mainly on the use of spirometry, which is an effort-dependent test and requires good patient cooperation. Impulse oscillometry (IOS) is a non-volitional method that requires less effort and cooperation and presents advantages for geriatric patients. However, the clinical application value of IOS in geriatric patients with COPD remains unclear. AIM: The aim of this study was to investigate the clinical application value of IOS in geriatric patients with COPD...

BACKGROUND: Inhalants are the standard treatment for patients with bronchial asthma. Inaccurate inhaler use leads to inadequate therapeutic effects and unnecessary dosage increases. However, it is a challenge for practitioners to master the various devices available and train patients on the accurate use of inhalers. Thus, establishing a system to instruct patients on how to accurately use inhalers is essential. We prepared a DVD and accompanying user manual explaining the operation of each inhaler device used in Japan...

The impulse oscillometry (IOS) is recognized as a complementary method to spirometry in the diagnostics of obstructive pulmonary disorders. The IOS enables to measure total respiratory resistance (R5) and proximal respiratory resistance (R20), with the R5-R20 difference reflecting small airway resistance. This study seeks to evaluate the usefulness of R5-R20, maximal mid-expiratory flow (MMEF), and forced expiratory volume in 3 s/forced vital capacity ratio (FEV3/FVC), in the assessment of small airway obstruction in chronic obstructive pulmonary disease (COPD)...

Emotional stimuli elicit airway constriction in individuals with asthma and in healthy individuals, but little is known about effects of repeated stimulation. We therefore explored the effect of repeated emotion induction on respiratory resistance (Rrs) using unpleasant, high-arousal surgery films and investigated effects of respiration and emotional reactivity. Twenty-six participants (13 with asthma) watched a series of 12 short, 45-s surgery films followed by 2-min recovery periods. Rrs assessed with impulse oscillometry was significantly elevated during films in both groups compared to baseline and recovered quickly after that...

BACKGROUND: In chronic obstructive pulmonary disease (COPD) patients, small-airway dysfunction (SAD) is considered a functional hallmark of disease. However, the exact role of SAD in the clinical presentation of COPD is not yet completely understood; moreover, it is not known whether SAD may have a relationship with the impact of disease. OBJECTIVES: To evaluate the prevalence of SAD among COPD patients categorized by the old and the new GOLD classification and to ascertain whether there is a relationship between SAD and impact of disease measured by the COPD Assessment Test (CAT) questionnaire...

Diagnosis and management of asthma often relies mostly on symptoms because spirometry is not always reliable in some age groups, such as preschoolers. It is unclear whether impulse oscillometry (IOS) can supplement or replace spirometry. Available reports suggest that IOS has been applied with success in asthmatic children and adolescents to assess exacerbations, level of control, severity and response to treatment in the short and long term. Very few studies using adequate sample sizes and methods have been performed comparing the accuracy of IOS to spirometry for the diagnosis of asthma...

INTRODUCTION: Early origins of chronic obstructive pulmonary disease have been recognized. Impulse oscillometry (IOS) is suitable for assessment of lung function also in preschool children, and some novel indices have been connected to assessment of small airway function. However, limited data exist on the sensitivity of these new indices to detect lung function deficits in young symptomatic children. METHODS: IOS measurements of 103 healthy preschool children were evaluated to establish reference equations for the difference between respiratory resistance at 5 and 20 Hz (R5-20), the relative difference of R5-20 (R5-20%), and area under the reactance curve (AX)...

Patch formulation of tulobuterol has been used in asthma treatment as a long-acting β2 -agonist (LABA) through sustained skin absorption. Its treatment efficacy, especially in small airways, remains poorly understood. The study aim was to investigate LABA add-on effects of tulobuterol patch (TP) and salmeterol inhaler (SA) on pulmonary function, asthma control and health status. Patients who had adult-onset under-control asthma, despite taking inhaled corticosteroids, were enrolled in a randomized, open-label, parallel-group, proof-of-concept study of 12-week add-on treatment with TP (n=16) or SA (n=17)...

INTRODUCTION AND OBJECTIVES: The invasive techniques can be direct and objective to assess small airway function, but they have significant risks and inconveniences for patients and can not be repeated often. Some sophisticated techniques such as fractional exhaled nitric oxide (FeNO) and impulse oscillometry (IOS) may surmount such restrictions. Therefore, we investigated the relation among FeNO, IOS and small airway function in asthmatic patients. METHODS: We recruited 140 asthmatic patients including 69 patients with small airway normal function and 71 patients with small airway dysfunction...

BACKGROUND: Diagnosing asthma in children is a challenge and using a single biomarker from exhaled breath condensate (EBC) showed the lack of improvement in it. OBJECTIVE: The aim of this study was to assess the diagnostic potential of a pattern of simple chemical biomarkers from EBC in diagnosing asthma in children in a real-life setting, its association with lung function and gastroesophageal reflux disease (GERD). METHODS: In 75 consecutive children aged 5-7 years with asthma-like symptoms the following tests were performed: skin prick tests, spirometry, impulse oscillometry (IOS), exhaled NO (FENO), 24-hour oesophageal pH monitoring and EBC collection with subsequent analysis of pH, carbon dioxide tension, oxygen tension, and concentrations of magnesium, calcium, iron and urates...
