Eilo

PURPOSE: Exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (EILO) are the two disorders commonly considered when athletes complain of exertional dyspnea. They are highly different but often confused. We aimed to address this diagnostic challenge and its consequences in elite athletes. METHODS: We included all athletes competing at national or international level, referred to our institution for workup for EILO during 2013-2016...

PURPOSE: Exercise-induced laryngeal obstruction (EILO) is relatively common in young people. Treatment rests on poor evidence; however, inspiratory muscle training (IMT) has been proposed a promising strategy. We aimed to assess laryngeal outcomes shortly after IMT, and to compare self-reported symptoms with a control group 4-6 years later. METHODS: Two groups were retrospectively identified from the EILO-register at Haukeland University Hospital, Norway; one group had received only information and breathing advice (IBA), and another additionally IMT (IBA + IMT)...

Exercise-induced laryngeal obstruction (EILO) is common, but we lack readily available diagnostic tools. The larynx represents an important point of resistance in the airways, and we therefore hypothesized that EILO is associated with characteristic breathing patterns possible to record from a standard incremental ergospirometry test. We studied 24 individuals with moderate/severe EILO and 20 individuals with no-EILO, mean (SD) age 17 (6.1) and 24 (6.4) years, respectively. EILO versus no-EILO was verified from maximal continuous laryngoscopy treadmill exercise (CLE) tests, which also included ergospirometry...

BACKGROUND: Self-reported exercise-induced dyspnea (EID) is common among adolescents. Possible underlying pathologies are exercise-induced bronchoconstriction (EIB) and laryngeal obstruction (EILO). The forced oscillation technique (FOT) may evaluate exercise-induced changes in airway caliber. AIM: To investigate in adolescents the relationship between EID, EIB (post-exercise fall in forced expiratory volume in 1s (FEV1 )≥10%), EILO, and post-exercise challenge changes in FOT parameters...

BACKGROUND: With concern over the rise in mental health symptoms associated with the COVID-19 pandemic, the present study set out to address the absence of pandemic-specific screening tools for detecting those in Chinese societies who are at-risk for experiencing mental distress due to the pandemic; thus, its aim was to validate the Coronavirus Anxiety Scale (CAS) and Obsession with COVID-19 Scale (OCS) in Chinese adults. METHODS: With a two-stage cluster random sampling method, we surveyed 1011 Chinese community-dwelling adults (38...

BACKGROUND: Exercise-induced laryngeal obstruction (EILO) is an exercise-dependent dyspnoea, linked to a laryngeal closure during physical effort. It may concern from 5% to 7% of adolescents and young athletic adults. EILO is a quite recently described condition: standardized diagnostic criteria and consensual management are still to come. Formal diagnosis of EILO requires a continuous laryngoscopy during exercise (CLE). This test allows visualization of laryngeal abnormalities during an effort but is only accessible in specialized centres...

Many adolescent sport performers present with exercise-related respiratory symptoms consistent with exercise-induced laryngeal obstruction (EILO). The pathogenic underpinnings of EILO are not fully resolved and existing behavioral management include therapies targeting laryngeal physiology while surgical interventions target laryngeal anatomical anomalies. Recent findings from research and clinical practice indicate that psychological stress and thoracic breathing co-occur with laryngeal tightness in adolescent sport performers with EILO...

BACKGROUND: Exercise-induced laryngeal obstruction (EILO) causes exertional dyspnea and is important for its effect on quality of life, diagnostic confusion with exercise-induced asthma, and health care resource utilization. There is no validated patient-reported outcome measure specific to EILO. OBJECTIVE: We sought to develop, validate, and define a minimal clinically important difference for a patient-reported outcome measure to be used with adolescents and young adults with EILO...

Background: Exercise-induced laryngeal obstruction (EILO) is common in young people with exertional breathing difficulties. Psychological characteristics have been proposed as underlying contributors; however, the evidence for this is limited. Objectives: Describe self-reported health, self-efficacy, and anxiety symptoms in adolescents with EILO, and address possible associations with EILO subtypes and severity. Methods: Cross-sectional study of 71/180 (39%) adolescents tested for EILO at Haukeland University Hospital during 2014-2016, age range 14-18 years...

BACKGROUND: Exercise-induced laryngeal obstruction (EILO) is a common cause of exertional breathlessness and wheeze yet is frequently misdiagnosed as asthma. Insight regarding the demographic characteristics, laryngeal abnormalities and impact of EILO is currently limited, with data only available from individual centre reports. The aim of this work was to provide a broader perspective from a collaboration between multiple international expert centres. METHODS: Five geographically distinct clinical paediatric and adult centres (3 Denmark, 1 UK, 1 USA) with an expertise in assessing unexplained exertional breathlessness completed database entry of key characteristic features for all cases referred with suspected EILO over a 5-year period...

Smartphone technologies have played a crucial role in the fight against the COVID-19 pandemic; however, the increased use of smartphones during the pandemic period may expose the general public to a higher risk of problematic smartphone use (PSU). This study aimed to estimate the prevalence of PSU among Chinese community adults and adopted a social-cognitive theory and social axiom framework to evaluate the effects of beliefs on PSU. A Chinese adult sample ( N = 616) was obtained through probability sampling via a telephone survey from Macao, China and included 591 smartphone users' data (39...

In order to propose better mental health interventions under the pandemic threat, the present study aimed to investigate whether depression and anxiety are associated to Chinese adults' perceptions of government's pandemic responses and the personal lifestyle changes imposed by those responses during the COVID-19 pandemic. We used a telephone survey with random sampling and obtained a probability community sample of 616 adults (39.1% men; M age  = 41.7, SD age  = 16.3) in Macao, China in April 2020. The prevalence of 8...

The diagnosis of exercise-induced laryngeal obstruction (EILO) should be suspected when exercise triggers inspiratory stridor. EILO is common in adolescent populations and has a significant impact on sports. Identification of laryngeal obstruction during continuous laryngoscopy during exercise (CLE) is the gold standard diagnostic tool for this disorder, which is not widely known in France. The challenge faced by otolaryngologists is to identify, among patients referred by pulmonologists or sports physicians, those with exercise-induced inspiratory symptoms or poorly controlled exercise-induced asthma, in whom a diagnosis of EILO is strongly suspected...

INTRODUCTION: Exercise-induced laryngeal obstruction (EILO) is a differential diagnosis for asthma and prevalent in athletes referred for exercise-induced dyspnea. The aim of this study was to estimate the prevalence of EILO in elite cross-country skiers, known for a high prevalence of asthma. METHOD: Elite cross-country skiers were invited for screening of EILO. Screening consisted of clinical assessment, questionnaires, skin prick test, spirometry, eucapnic voluntary hyperventilation test, and continuous laryngoscopy during exercise test...

Exertional dyspnoea among children and adolescents is a common presenting complaint to general practitioners. Exertional dyspnoea is most commonly attributed to exercise-induced bronchoconstriction (EIB), but there are several other causes including hyperventilation syndrome, breathlessness associated with normal exercise limitation and exercise-induced laryngeal obstruction (EILO). The symptoms of EILO include stridor, throat tightness and difficulty on inspiration. If these are mistaken for EIB, children will receive asthma therapy...

BACKGROUND: In the face of the global pandemic of coronavirus disease-2019 (COVID-19), people's adherence to precautionary behavioral measures (e.g. social distancing) largely influences the effectiveness of those measures in containing the spread of the coronavirus. The present study aims at testing the applicability of the health belief model (HBM) and generalised social beliefs (i.e. social axioms) to explore strategies for promoting adherence to COVID-19 precautionary measures. METHODS: We conducted a telephone survey with a two-step stratified random sampling method and obtained a probability sample of 616 adults in Macao, China (18-87 years old; 60...

OBJECTIVES: To study the prevalence of exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (EILO) in adolescent athletes. METHODS: All adolescents (n = 549) attending first year at a sports high school in 2016 and 2017, were invited to answer a questionnaire on respiratory symptoms. The 367 responding participants were divided into two groups based on whether they reported exercise-induced dyspnea (dyspnea group) or not (nondyspnea group)...

OBJECTIVE: Exercise-induced laryngeal obstruction (EILO) occurs with paradoxical vocal fold motion or supraglottic collapse during moderate to vigorous exercise. Previously, Gallena et al (2015) reported lower-than-normal inspiratory (Ri ) and expiratory (Re ) resistances during resting tidal breathing (RTB) in female teenage athletes with EILO. This study aimed to replicate that unexpected result. METHOD: The Airflow Perturbation Device measured Ri and Re during three 1-minute trials of RTB in 16 teenage female athletes with EILO and 16 sex-, age-, and height-matched controls...

METHODS: We retrospectively audited the health records of 18 patients with breathing pattern disorders (BPDs), who were diagnosed in our respiratory clinic (2015-2018), and then referred onto our dysfunctional breathing care pathway to a specialist speech and language therapist. RESULTS: The age of the patients ranged from 11 to 16 years (median: 14 years, 14 female/4 male patients). Comorbidities included the following: 16 patients had asthma, 2 patients had a tracheoesophageal fistula and esophageal atresia repair, one patient suffered from chronic regional pain syndrome, and one patient had chronic fatigue syndrome...

Breathlessness during sport can be caused by various cardiorespiratory conditions, but when associated with stridor, usually arises from an upper airway etiology. The term exercise-induced laryngeal obstruction (EILO) is now used to describe the phenomenon of transient glottic closure occurring in association with physical activity. Exercise-related laryngeal closure is most commonly encountered in athletic individuals and likely affects between 5% and 7% of all young adults and adolescents. The diagnosis of EILO is not always straightforward because features can overlap with exercise-induced asthma/exercise-induced bronchoconstriction...
