Fujiki RB, Johnson R, Fujiki AE, Thibeault SL. Effects of Exercise-Induced Laryngeal Obstruction in Adolescents: A Qualitative Study. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2024; 33:1911-1929. [PMID: 38728156 PMCID: PMC11253634 DOI: 10.1044/2024_ajslp-23-00296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 12/09/2023] [Accepted: 03/25/2024] [Indexed: 05/12/2024]
Abstract
PURPOSE The purpose of this study was to examine the influence of exercise-induced laryngeal obstruction (EILO) on adolescents. METHOD Twenty patients (< 17 years) diagnosed with EILO participated in this study. Patients completed semistructured interviews examining their experience with the health care system, treatment, and the effects of EILO symptoms on quality of life. Interviews were analyzed using a combination of directed and conventional content analyses. Researchers identified seven overarching themes either prior to or during analysis, and 24 subthemes were inductively identified from patient interviews using open, axial, and selective coding. RESULTS On average, patients went 1.9 years between symptom onset and EILO diagnosis. Patients described symptom onset as frightening and confusing. Even after initially reporting symptoms to a medical provider, patients went an average of 10.5 months before diagnosis. Patients perceived that delays in diagnosis prevented efficient management and allowed symptoms to escalate. Patients reported that EILO detrimentally influenced athletic performance, forcing them to pace themselves or cease participation altogether. Social and academic effects of EILO included missed classes, difficulty in physical education courses, and resentment from teammates if athletic performance declined. Both athletes and nonathletes indicated that EILO elicited feelings of fear, frustration, dread, guilt, and embarrassment. Patients reported that therapy with a speech-language pathologist (SLP) effectively addressed symptoms; however, employing rescue breathing techniques was often more difficult than anticipated. CONCLUSIONS Physical and emotional sequelae associated with EILO may have widespread influence on patient quality of life. Therapy with an SLP reportedly ameliorated EILO symptoms; however, patients indicated that delayed diagnosis allowed negative effects to intensify prior to treatment.

Abstract
PURPOSE Diagnosing pediatric induced laryngeal obstruction (ILO) requires equipment typically available in specialist settings, and patients often see multiple providers before a diagnosis is determined. This study examined the financial burden associated with the diagnosis and treatment of ILO in pediatric patients with reference to socioeconomic disadvantage. METHODS Adolescents and children (<18 years of age) diagnosed with ILO were identified through the University of Madison Voice and Swallow Outcomes Database. Procedures, office visits, and prescribed medications were collected from the electronic medical record. Expenditures were calculated for two time periods (1) pre-diagnosis (first dyspnea-related visit to diagnosis), and (2) the first year following diagnosis. The Area Deprivation Index (ADI) was used to estimate patient socioeconomic status to determine if costs differed with neighborhood-level disadvantage. RESULTS A total of 113 patients met inclusion criteria (13.9 years, 79% female). Total pre-diagnosis costs of ILO averaged $6486.93 (SD = $6604.14, median = $3845.66) and post-diagnosis costs averaged $2067.69 (SD = $2322.78; median = $1384.12). Patients underwent a mean of 3.01 (SD = 1.9; median = 2) procedures and 5.8 (SD = 4.7; median = 5) office visits prior to diagnosis. Pharmaceutical, procedure/office visit, and indirect costs significantly decreased following diagnosis. Patients living in neighborhoods with greater socioeconomic disadvantage underwent fewer procedures and were prescribed more medication than those from more affluent areas. However, total expenditures did not differ based on ADI. CONCLUSIONS Pediatric ILO is associated with considerable financial costs. The source of these costs, however, differed according to socioeconomic advantage. Future work should determine how ILO diagnosis and management can be more efficient and equitable across all patients. Laryngoscope, 134:3384-3390, 2024.

Abstract
OBJECTIVE The prevalence of exercise-induced laryngeal obstruction is largely unknown. This study aimed to evaluate the prevalence of this condition in a selected study population of patients with exercise-induced dyspnoea. METHOD A retrospective analysis was conducted of demographic data, co-morbidities, medication, symptoms, performance level of sporting activities, continuous laryngoscopy exercise test results and subsequent treatment. RESULTS Data from 184 patients were analysed. The overall prevalence of exercise-induced laryngeal obstruction in the study population was 40 per cent, and the highest prevalence was among females aged under 18 years (61 per cent). However, a high prevalence among males aged under 18 years (50 per cent) and among adults regardless of gender (34 per cent) was also found. CONCLUSION The prevalence of exercise-induced laryngeal obstruction is clinically relevant regardless of age and gender. Clinicians are encouraged to consider exercise-induced laryngeal obstruction as a possible diagnosis in patients suffering from exercise-induced respiratory symptoms. No single characteristic that can distinguish exercise-induced laryngeal obstruction from other similar conditions was identified.

Abstract
PURPOSE This study examined treatment outcomes of speech-language pathology intervention addressing exercise-induced laryngeal obstruction (EILO) symptoms in teenage athletes. METHOD A prospective cohort design was utilized; teenagers diagnosed with EILO completed questionnaires during initial EILO evaluations, posttherapy, 3-month posttherapy, and 6-month posttherapy. Questionnaires examined the frequency of breathing problems, the use of the techniques taught in therapy, and the use of inhaler. Patients completed the Pediatric Quality of Life (PedsQL) inventory at all time points. RESULTS Fifty-nine patients completed baseline questionnaires. Of these, 38 were surveyed posttherapy, 32 at 3-month posttherapy, and 27 at 6-month posttherapy. Patients reported more frequent and complete activity participation immediately posttherapy (p = .017) as well as reduced inhaler use (p = .036). Patients also reported a significant reduction in the frequency of breathing problems 6-month posttherapy (p = .015). Baseline PedsQL physical and psychosocial scores were below normative range and were not impacted by therapy. Baseline physical PedsQL score significantly predicted frequency of breathing difficulty 6-month posttherapy (p = .04), as better baseline scores were associated with fewer residual symptoms. CONCLUSIONS Therapy with a speech-language pathologist for EILO allowed for more frequent physical activity following therapy completion and decreased dyspnea symptoms 6-month posttherapy. Therapy was associated with a decrease in inhaler use. PedsQL scores indicated mildly poor health-related quality of life even after EILO symptoms improved. Findings support therapy as an effective treatment for EILO in teenage athletes and suggest that dyspnea symptoms may continue to improve following discharge as patients continue using therapy techniques.

Abstract
OBJECTIVE Vocal cord dysfunction is inappropriate adduction of vocal cords during inspiration that causes dyspnea and is commonly mistaken for exercise-induced asthma. To improve diagnostic accuracy, this study aims to identify demographics associated with vocal cord dysfunction and to determine their impact on the efficacy of voice therapy in improving vocal cord function. STUDY DESIGN Retrospective chart review. SETTING Single tertiary care institution between January 2015 and December 2021. METHODS 184 patients who underwent voice therapy for vocal cord dysfunction were included. The primary outcome was patient self-reported percent improvement of symptoms. The secondary outcome was number of voice therapy treatments. RESULTS The mean duration of symptoms was 2 ± 3 years. The mean number of voice therapy treatments was 2.2 ± 1.5. Of the 107 (58.2 %) patients with documented perceived breathing improvement percentages recorded, the mean maximal percent improvement was 72.5 ± 21.5 %. Mean maximal percent improvement of symptoms increased with each voice therapy treatment (p = 0.01). This association remained significant when controlling for comorbid conditions such as allergic rhinitis with postnasal drip, anxiety, asthma, and gastroesophageal reflux disease in multivariate analysis (p = 0.005). Patients with asthma had significantly higher maximum percent breathing improvement compared to those without asthma (p = 0.026). Similarly, patients who played sports had significantly higher maximum percent breathing improvement compared to those who did not (p = 0.022). CONCLUSION Patient perceived breathing improvement with voice therapy is higher among those with concomitant asthma and those who play sports. Voice therapy is a safe and effective first line treatment of vocal cord dysfunction even when controlling for comorbid conditions.

The impact of identifying laryngeal obstruction syndromes on reducing treatment of pediatric asthma: A systematic review. Pediatr Pulmonol 2022; 57:1401-1415. [PMID: 35355450 PMCID: PMC9321614 DOI: 10.1002/ppul.25910] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 03/18/2022] [Accepted: 03/23/2022] [Indexed: 11/11/2022]
Abstract
Inducible laryngeal obstruction (ILO) in children is underrecognized. This systematic review characterizes the scientific evidence on the impact of pediatric ILO diagnosis and treatment on asthma medication use. This review, registered with PROSPERO (CRD42020209168), utilized database searches in MEDLINE, EMBASE, CINAHL, and Web of Science from inception to October 2020. Both experimental and observational studies on ILO and asthma outcomes in patients ≤18 years were included. Population characteristics (sample size, sex, age, and comorbidities) and study outcomes (medication usage and respiratory symptoms) were extracted. The risk of bias was assessed with the National Toxicology Program's Office of Health Assessment and Risk of Bias Rating Tool. Data are presented narratively due to study heterogeneity. Of 1091 studies, 1076 titles and abstracts were screened after duplicate removal. Screening 31 full texts yielded eight pre-post studies. Patients were an average of 14.1 years old, 15% male, and >90% used asthma medication; 40% reported allergies, 30% gastroesophageal reflux, and 20% anxiety or depression. Most patients received at least one intervention, with 75% showing symptomatic improvement and >75% decreasing or stopping asthma medications. Studies were small with a high risk of selection, confounding, and detection bias. Asthma management was not a primary outcome in any of the studies. Overall, ILO patients were often diagnosed with or treated for asthma before ILO diagnosis. Evidence from individual studies suggests that comorbidities including ILO, gastroesophageal reflux, allergies, and anxiety should be considered in pediatric patients with asthma not responsive to medical therapy. Further research is required to determine the proportion of impacted asthma patients.

Abstract
OBJECTIVE Exercise-induced respiratory symptoms (EIS) are common in childhood and reflect different diseases that can be difficult to diagnose. In children referred to respiratory outpatient clinics for EIS, we compared the diagnosis proposed by the primary care physician with the final diagnosis from the outpatient clinic and described diagnostic tests and treatments. DESIGN An observational study of respiratory outpatients aged 0-16 years nested in the Swiss Paediatric Airway Cohort (SPAC). PATIENTS We included children with EIS as the main reason for referral. Information about diagnostic investigations, final diagnosis, and treatment prescribed came from outpatient records. We included 214 children (mean age 12 years, range 2-17, 54% males) referred for EIS. RESULTS The final diagnosis was asthma in 115 (54%), extrathoracic dysfunctional breathing (DB) in 35 (16%), thoracic DB in 22 (10%), asthma plus DB in 23 (11%), insufficient fitness in 10 (5%), chronic cough in 6 (3%), and other diagnoses in 3 (1%). Final diagnosis differed from referral diagnosis in 115 (54%, 95%-CI 46%-60%). Spirometry, body plethysmography, and exhaled nitric oxide were performed in almost all, exercise-challenge tests in a third, and laryngoscopy in none. 91% of the children with a final diagnosis of asthma were prescribed inhaled medication and 50% of children with DB were referred to physiotherapy. CONCLUSIONS Diagnosis given at the outpatient clinic often differed from the diagnosis proposed by the referring physician. Diagnostic evaluations, management, and follow-up differed between clinics and diagnostic groups highlighting the need for evidence-based diagnostic guidelines and harmonized procedures for children seen for EIS.

Int J Pediatr Otorhinolaryngol 2019; 127:109677. [PMID: 31526937 DOI: 10.1016/j.ijporl.2019.109677] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Revised: 09/07/2019] [Accepted: 09/08/2019] [Indexed: 10/26/2022]
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.

Zalvan C, Yuen E, Geliebter J, Tiwari R. A Trigger Reduction Approach to Treatment of Paradoxical Vocal Fold Motion Disorder in the Pediatric Population. J Voice 2019; 35:323.e9-323.e15. [PMID: 31537408 DOI: 10.1016/j.jvoice.2019.08.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2019] [Revised: 08/14/2019] [Accepted: 08/15/2019] [Indexed: 12/12/2022]
Abstract
OBJECTIVES Paradoxical vocal fold motion disorder (PVFMD), or induced laryngeal obstruction (ILO), is a clinical phenomenon characterized by inappropriate adduction of the true vocal folds during inspiration. The resultant episodes of acute respiratory distress marked by exercise-induced cough, inspiratory stridor, throat tightness, and shortness of breath are often misattributed to asthma despite normal pulmonary function testing results. Although the pathogenesis of the disease remains unclear, the etiology is likely multifactorial with an inflammatory, neurological, and psychiatric basis. Our trigger reduction approach, consisting of a plant-based, Mediterranean-style diet to treat laryngopharyngeal reflux and sinus toilet, aims to dampen the peripheral neuronal hyperexcitability of the laryngopharyngeal tissues that is hypothesized to contribute to this disorder. The primary objective of the present study was to assess for therapeutic efficacy by analyzing pre- and post-treatment subjective scores using four validated indices: Voice Handicap Index (VHI), Reflux Symptom Index (RSI), Dyspnea Index (DI), and Cough Severity Index (CSI). METHODS A retrospective chart review of all patients age ≤18 years seen by the senior author between 2012 and 2018 who reported laryngeal spasm (J35.5) as a presenting complaint with no underlying organic diagnosis that otherwise explained the symptom identified the study cohort. Patients were excluded if another cause of their laryngeal spasm was identified or their medical records were incomplete. RESULTS Of 80 patients, 24 met the criteria. The most frequent presenting symptom was exercise-induced dyspnea (79%). Of the four measured indices, only a change in DI (P = 0.024) met statistical significance. Of 24 patients, 18 (75%) demonstrated a reduction in DI following our treatment protocol. Using reduction in DI as a continuous variable to assess response, the patient cohort experienced a 4.62 (95% confidence interval [CI]: 0.65-8.6) mean point reduction. Using the eight-point reduction (improvement) in DI as an accepted clinical response to treatment, 8 of 24 patients (33%) experienced a clinically relevant response. Changes in CSI (P = 0.059), RSI (P = 0.27), and VHI (P = 0.25) did not meet statistical significance. Of 24 patients, 8 (33%), 11 (46%), and 7 (29%) demonstrated a reduction in CSI, RSI, and VHI following our trigger reduction protocol, respectively. The patient cohort experienced a mean point reduction of 1.8 (95% CI: -0.1 to 3.7), 1.3 (95% CI: -1.1 to 3.7), and 1.3 (95% CI: -1.0 to 3.6) in CSI, RSI, and VHI, respectively. CONCLUSIONS Paradoxical vocal fold motion disorder is a multifactorial disease that poses diagnostic and therapeutic challenges. Early diagnosis and treatment are critical to ensure patient safety, satisfaction, and reduction in health care costs, as mistreatment with asthma pharmacotherapy, intubation, or tracheostomy may exacerbate their dyspnea and lead to preventable hospitalizations. Our results demonstrate that a trigger reduction approach consisting of a plant-based, Mediterranean-style diet and sinus toilet alone may not achieve a clinically meaningful response in the majority of patients. However, given their favorable safety profile, our therapeutic regimen, along with respiratory retraining therapy, may provide symptom relief for selected patients who would otherwise continue to suffer.

Abstract
Vocal cord dysfunction (VCD) is an upper airway disorder characterized by exaggerated and transient glottic constriction causing respiratory and laryngeal symptoms. Although the origin of VCD symptoms is in the upper airway, it is frequently misdiagnosed as asthma resulting in significant morbidity. VCD can coexist with asthma or mimic allergic conditions affecting the upper airway. VCD may be difficult to diagnose, because patients are intermittently symptomatic and VCD awareness in the medical community is underappreciated. Once VCD is diagnosed and treated, most patients report significant improvement in their symptoms as well as a decrease in asthma medication use.

Abstract
The syndromology of dysfunction of the vocal cords varies widely from the absence of symptoms to mild shortness of breath to acute respiratory disfunction, which can mimic an asthma attack. The treatment of vocal dysfunction and bronchial asthma is different. An early fold diagnosis of vocal dysfunction can prevent improper treatment and, therefore, minimize the rising costs of health care.

Abstract
Exertional dyspnea is common in health and disease. Despite having known for centuries that breathlessness can arise from the larynx, exercise-induced laryngeal obstruction is a more prevalent condition than previously assumed. This article provides a brief overview of the history, epidemiology, and pathophysiology of exercise-induced laryngeal obstruction.

Abstract
Inducible laryngeal obstruction (ILO) is a complex entity and its exact mechanisms are still unclear. It is characterised by transient and reversible narrowing of the larynx in response to external triggers, resulting in symptoms such as cough, dyspnoea and noisy breathing. The prevalence of this condition in adult or paediatric populations is uncertain. Management of ILO starts by establishing an accurate diagnosis, and treatment includes control of trigger factors, breathing and relaxation techniques, and speech and respiratory therapy. The aim of this article is to summarise current understanding and provide a review of the literature of ILO in the paediatric population.

Abstract
Vocal cord dysfunction (VCD)-associated symptoms are not rare in pediatric patients. Dyspnea, wheezing, stridor, chest pain or tightness and throat discomfort are the most commonly encountered symptoms. They may occur either at rest or more commonly during exercise in patients with VCD, as well as in asthmatic subjects. The phase of respiration (inspiration rather than expiration), the location of the wheezing origin, the rapid resolution of symptoms, and the timing occurring in relation to exercise, when VCD is exercise induced, raise the suspicion of VCD in patients who may have been characterized as merely asthmatics and, most importantly, had not responded to the appropriate treatment. The gold standard method for the diagnosis of VCD is fiberoptic laryngoscopy, which may also identify concomitant laryngeal abnormalities other than VCD. However, as VCD is an intermittent phenomenon, the procedure should be performed while the patient is symptomatic. For this reason, challenges that induce VCD symptoms should be performed, such as exercise tests. Recently, for the evaluation of patients with exercise-induced VCD, continuous laryngoscopy during exercise (such as treadmill, bicycle ergometer, swimming) was used. A definite diagnosis of VCD is of importance, especially for those patients who have been erroneously characterized as asthmatics, without adequate response to treatment. In these cases, another therapeutic approach is necessary, which will depend on whether they suffer solely from VCD or from both conditions.
