Abstract
Importance Patients with induced laryngeal obstruction (ILO) present with a variety of behavioral health profiles. Identifying these profiles is crucial in that behavioral health conditions may affect treatment duration and outcomes. Objective To characterize the prevalence of anxiety, depression, posttraumatic stress disorder (PTSD), and physical somatic symptoms in adult and pediatric patients with ILO and determine the factors associated with anxiety, depression, PTSD, and physical somatic symptoms in patients with ILO? Design, Setting, and Participants This cross-sectional study included a nonprobability sample of 83 adult and 81 pediatric patients diagnosed with ILO at outpatient adult and pediatric otolaryngology clinics between 2021 and 2023. Exclusion criteria included a comorbid respiratory diagnosis other than asthma, head or neck cancer, or neurological impairments. Recruitment took place between September 2021 and March 2023. The analyses were run in January 2024. Main Outcome Measures Patients were prospectively screened for anxiety, depression, PTSD, and somatic physical symptoms. In addition, any past behavioral health diagnoses were extracted from the medical record. Comorbidities, ILO symptoms triggers, and onset details were gathered from ILO evaluations. Adult patients completed the Screen for Adult Anxiety Related Disorders (SCAARED), depression (Patient Health Questionnaire [PHQ]-9), and somatic physical symptoms portions of the Patient Health Questionnaires (PHQ-15), and the PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (PCL-5). Pediatric patients completed the Screen for Child Anxiety Related Disorders (SCARED), depression (PHQ-9A) and somatic physical symptoms portions of the Patient Health Questionnaires for Adolescents (PHQ-15A), and the UCLA PTSD Reaction Index brief screeners. Results Eighty-three adult patients participated in this study (mean [SD] age, 45.8 [14.3] years; 64 female, 19 male). Eighty-one pediatric patients participated (mean [SD] age, 13.83 [2.55] years; 67 female, 14 male). Adult and pediatric patients with ILO screened positive for elevated rates of anxiety (53 adults [63%]; 49 children [60%]), depression (27 adults [32%]; 25 children [30%]), and PTSD (29 adults [34%]; 13 children [16%]). Most of the patients with anxiety and depression symptoms were formally diagnosed prior to ILO evaluation, with rates of previously diagnosed anxiety, depression, and PTSD also above published norms. Adults were twice as likely as children to present with PTSD (odds ratio, 2.1; 95% CI, 0.05-4.48). Elevated rates of physical somatic symptoms were also evident, with 38 adults (45%) and 32 children (39%) scoring in the moderate to severe range. Conclusions and Relevance This study found high rates of adult and pediatric patients with ILO screened positive for anxiety, depression, and PTSD symptoms. Future work should investigate how behavioral health and ILO treatments can best be coordinated to maximize treatment outcomes.

Abstract
PURPOSE Exercise-induced laryngeal obstruction (EILO) is suspected when dyspnea associated with upper airway symptoms is triggered by exercise. This condition affects mainly adolescent athletes. Visualization of the obstruction, while the patient is experiencing the symptoms during continuous laryngoscopy during exercise (CLE-test) is the gold standard for diagnosing EILO. Our study aims to evaluate the prevalence of EILO in a population presenting exercise-induced inspiratory symptoms (EIIS) or uncontrolled asthma with exertional symptoms. The second objective was to evaluate the diagnostic strength of laryngology consultation (LC) and pulmonary function tests (PFTs). METHODS All patients referred to our center for EIIS or uncontrolled asthma with exertional symptoms were included. EILO diagnosis was made if Maat score was > 2 for patients with CLE-test or if there were inspiratory anomalies on PFTs and LC. The sensitivity and specificity of LC and PFTs as diagnostic tools were calculated considering CLE-test as the gold standard. RESULTS Sixty two patients were referred to our center for EIIS or uncontrolled asthma with exertional symptoms. EILO was diagnosed in 28 patients (56%) with associated asthma in 9 patients (18%). The sensibility and specificity of LC for supraglottic anomalies were 75% and 60%, respectively. The sensibility and specificity of PFTs were 61% and 89%, respectively. CONCLUSIONS There was a high prevalence of EILO among patients with EIIS and uncontrolled asthma. Some clinical characteristics might guide the diagnosis. Nevertheless, CLE-test remained the gold standard for EILO diagnosis and identification of the dysfunctional upper airway site to provide specific management.

Abstract
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. Current asthma was defined as physician-diagnosed asthma and use of asthma medication during the last 12 months. EILO was defined as ≥2 points at the supraglottic or glottic level during exercise at maximal effort, using a visual grade score system. RESULT A total of 89 (51% female) cross-country skiers completed the study. EILO was identified in 27% of the skiers, 83% of whom were female. All skiers with EILO had supraglottic EILO, and there was no glottic EILO. Current asthma was present in 34 (38%) of the skiers, 10 (29%) of whom had concomitant EILO. In the skiers with EILO, a higher proportion reported wheeze or shortness of breath after exercise, compared with skiers without EILO. In skiers with EILO and current asthma, compared with skiers with asthma only, a higher proportion reported wheeze or shortness of breath after exercise. Asthma medication usage did not differ between these groups. CONCLUSION EILO is common in elite cross-country skiers, especially females. Asthma and EILO may coexist, and the prevalence of respiratory symptoms is higher in skiers with both. Testing for EILO should be considered in cross-country skiers with respiratory symptoms.

Abstract
OBJECTIVES To explore long-term patient reported outcome (PRO) measures of pediatric paradoxical vocal cord motion (PVCM) including ease of diagnosis, management, symptom duration and effect on quality of life. METHODS All children >8 years of age diagnosed with PVCM at a tertiary pediatric hospital between 2006 and 2017 were invited to complete a survey addressing study objectives. RESULTS 21/47 eligible participants could be contacted and 18/21 (86%) participated. 78% were female with a mean age at diagnosis of 11.6 and 15.0 years at survey completion. Common PVCM symptoms reported were dyspnea (89%), globus sensation (56%), and stridor (50%). The median time to diagnosis was 3 months (IQR 2-5 months). Nearly all reported being misdiagnosed with another condition, usually asthma, until being correctly diagnosed usually by an otolaryngologist. Participants reported undergoing 3.7 diagnostic studies (range 0-8); pulmonary function testing was most common. Of numerous treatments acknowledged, breathing exercises were common (89%) but only reported helpful by 56%. Use of biofeedback was recalled in 1/3 of subjects but reported helpful in only 14% of them. Anti-reflux, allergy, anticholinergics, inhalers and steroids were each used in >50%, but rarely reported effective. PVCM was reportedly a significant stressor when initially diagnosed but despite 2/3 of participants still reporting ongoing PVCM symptoms, the perceived stress significantly decreased over time (Z = 3.26, P = 0.001). CONCLUSIONS This first PVCM PRO study endorses that diagnosis is often delayed and prescribed treatments often viewed as ineffective. While biofeedback and breathing exercises may be critical for short-term control of PVCM episodes, lifestyle changes and stress reduction are likely necessary for long-term management. Increased awareness and improvements in management are needed for this condition.

Abstract
INTRODUCTION Exercise-induced laryngeal obstruction (EILO) affects 2-3% of the general population and 5.1% of elite athletes. Symptoms arise during high-intensity exercise and resolve at rest. EILO is often misdiagnosed as exercise-induced asthma as both conditions can present with dyspnea, chest tightness and cough. The purpose of this quality initiative was to identify patient characteristics that predict a higher likelihood of EILO, streamline referrals for exercise-endoscopy testing and avoid unnecessary medications. METHODS A retrospective chart review included patients referred to a pediatric tertiary center between 2013 and 2018 for suspected EILO requesting exercise endoscopy. Data was collected from the patient chart and referral letters included age, sex, physical activity, medications, symptoms, and results of pulmonary and cardiac function tests. RESULTS Between 2013 and 2018, 35 patients (9 males and 26 females, aged 5-18 years) were referred. Only 18 patients developed symptoms during an exercise endoscopy test. The majority were female (15/18), older than 10 years (18/18) and were involved in competitive sports (16/18). Stridor was the most common complaint among all patients referred (24/35) and many reported anxiety and high stress (15/35). The majority (63%) were previously treated with asthma medication. Pulmonary and cardiac function testing was not predictive of EILO. CONCLUSION EILO is typically present in adolescent females involved in competitive sports. Anxiety and high stress was commonly noted. The majority were treated with asthma medication even though pulmonary function testing was normal. Recognition of this patient profile should improve timely access to appropriate diagnostic assessments, avoid unnecessary medical treatment, and promote a return to optimal athletic performance.

Abstract
INTRODUCTION Paradoxical vocal fold movement dysfunction (PVFMD) is a disorder in which the vocal folds involuntarily adduct during inspiration resulting in stridor, cough, dysphonia and dyspnea. Diagnosis of PVFMD is difficult given the episodic nature of the disorder and the often-normal laryngeal exam in between episodes. Moreover, additional sources of obstruction have been identified as sources of Periodic Occurrence of Laryngeal Obstruction (POLO). Treatments can vary with site of obstruction. OBJECTIVE To evaluate pediatric patients presenting to a Vocal Fold Dysfunction Center for evaluation of exertional, inspiratory, harsh breath sounds and dyspnea suggestive of PVFMD whom were found to have a dynamic obstruction of the upper airway due to adenotonsillar hypertrophy and prolapse. METHODS Retrospective chart review of patients diagnosed with exertional dynamic tonsillar prolapse whom have undergone adenotonsillectomy. Clinical characteristics, spirometry, exam findings and response to adenotonsillectomy were recorded. RESULTS Seven patients with exercise induced dyspnea and respiratory distress with whom underwent exercise spirometry then subsequent adenotonsillectomy were identified. Symptomatic co-morbidities were common and included: rhinitis (43%), reflux (29%), sleep disordered breathing (29%), asthma (14%), obesity (14%), prematurity (14%) and anxiety/post-traumatic stress disorder (PTSD) (14%). Preoperative use of bronchodilators or reflux medications was common. All patients were noted to have >50% oropharyngeal obstruction secondary to tonsillar hypertrophy and dynamic lateral pharyngeal collapse or tonsillar prolapse with inspiration. No exercise induced paradoxical vocal fold dysfunction was identified. All baseline and most exertion FVC, FEV1, FEV1/FVC and FEF 25-75% were normal. Four patients had flow volume loops suggestive of obstruction. All patients had symptomatic improvement after adenotonsillectomy. CONCLUSIONS Dynamic tonsillar prolapse can result in subjective exertional dyspnea and objective upper airway resistance mimicking PVFMD and treatment with adenotonsillectomy can greatly reduce symptoms.

Abstract
Vocal cord dysfunction is an obstruction of the upper airway, primarily on inspiration, due to the paradoxical adduction of the vocal cords. Vocal cord dysfunction continues to be underdiagnosed as its own entity. The lack of diagnosis can be attributed to the overlap of symptoms between asthma and exercise-induced bronchospasm. It is possible for patients diagnosed with asthma and/or exercise-induced bronchospasm to have underlying vocal cord dysfunction, which needs to be considered when prescribing asthma medications. This article will review the history of vocal cord dysfunction, the differential diagnosis, diagnostic testing, and the role of the nurse practitioner in caring for these patients.

Abstract
Exertional dyspnea is a common complaint in general pediatric practice. While a high proportion of the general pediatric population has asthma, other diagnoses, including exercise-induced laryngeal obstruction should be considered, especially when asthma therapy is not sufficient to control symptoms. This review describes some of the key clinical features of exercised-induced laryngeal obstruction as well as preferred diagnostic and therapeutic approaches. Importantly, current diagnostic technology has considerably improved in the last decade at specialty centers. At the same time, infrastructure for clinical trials is emerging and there is not strong evidence to support specific therapies at the current time.

Abstract
This international task force report updates general considerations for bronchial challenge testing and the performance of the methacholine challenge test. There are notable changes from prior recommendations in order to accommodate newer delivery devices. Rather than basing the test result upon a methacholine concentration (provocative concentration (PC20) causing a 20% fall in forced expiratory volume in 1 s (FEV1)), the new recommendations base the result upon the delivered dose of methacholine causing a 20% fall in FEV1 (provocative dose (PD20)). This end-point allows comparable results from different devices or protocols, thus any suitable nebuliser or dosimeter may be used, so long as the delivery characteristics are known. Inhalation may be by tidal breathing using a breath-actuated or continuous nebuliser for 1 min (or more), or by a dosimeter with a suitable breath count. Tests requiring maximal inhalations to total lung capacity are not recommended because the bronchoprotective effect of a deep breath reduces the sensitivity of the test.

Abstract
Exercise induced laryngeal obstruction (EILO) is a condition where inappropriate vocal cord or glottic closure occurs during exercise. This review of the literature provides an overview of the current understanding of the definition, epidemiology, diagnosis and management of EILO. Using The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines the Cochrane, Embase, Ovid MEDLINE and PubMed databases were searched. Four search domains “exercise”, “induced”, “laryngeal” and “obstruction” were used. Primary searching found 469 records, 308 were excluded following screening of titles and citation. 100 were duplicates, a further 47 studies were excluded after applying inclusion and exclusion criteria. Two studies were identified following cross-referencing. A total of 15 studies were included. The last search date was 6/06/15. Average prevalence in the general adolescent population and athletes was 7.1 and 35.2 %, respectively. Dyspnoea was reported in 96.5, 99 and 100 % of three EILO patient cohorts. Two studies (n = 107) reported continuous laryngoscopy during exercise (CLE) testing could differentiate between patients and controls. In two studies (n = 33) the visual analogue scale (VAS) showed a beneficial effect of endoscopic supraglottoplasty (ES). Thirty-eight out of 43 patients who received two or more laryngeal control therapy sessions (LCT) had improvement or resolution of EILO symptoms. Exercise induced dyspnoea is the most common EILO symptom. EILO has a high occurrence in adolescents and athletes. The CLE test is the current gold standard for EILO diagnostics. Management of EILO includes both surgical and non-surgical interventions.

Abstract
The first practice parameter on exercise-induced bronchoconstriction (EIB) was published in 2010. This updated practice parameter was prepared 5 years later. In the ensuing years, there has been increased understanding of the pathogenesis of EIB and improved diagnosis of this disorder by using objective testing. At the time of this publication, observations included the following: dry powder mannitol for inhalation as a bronchial provocation test is FDA approved however not currently available in the United States; if baseline pulmonary function test results are normal to near normal (before and after bronchodilator) in a person with suspected EIB, then further testing should be performed by using standardized exercise challenge or eucapnic voluntary hyperpnea (EVH); and the efficacy of nonpharmaceutical interventions (omega-3 fatty acids) has been challenged. The workgroup preparing this practice parameter updated contemporary practice guidelines based on a current systematic literature review. The group obtained supplementary literature and consensus expert opinions when the published literature was insufficient. A search of the medical literature on PubMed was conducted, and search terms included pathogenesis, diagnosis, differential diagnosis, and therapy (both pharmaceutical and nonpharmaceutical) of exercise-induced bronchoconstriction or exercise-induced asthma (which is no longer a preferred term); asthma; and exercise and asthma. References assessed as relevant to the topic were evaluated to search for additional relevant references. Published clinical studies were appraised by category of evidence and used to document the strength of the recommendation. The parameter was then evaluated by Joint Task Force reviewers and then by reviewers assigned by the parent organizations, as well as the general membership. Based on this process, the parameter can be characterized as an evidence- and consensus-based document.
