Fujiki RB, Thibeault SL. Diagnostic utility of spirometry for children with induced laryngeal obstruction or chronic non-specific cough. Am J Otolaryngol 2024; 45:104316. [PMID: 38677150 PMCID: PMC11168868 DOI: 10.1016/j.amjoto.2024.104316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Accepted: 04/15/2024] [Indexed: 04/29/2024]
Abstract
PURPOSE To determine the diagnostic utility of spirometry in distinguishing children with Induced Laryngeal Obstruction (ILO) or chronic non-specific cough (a.k.a. tic cough) from those with mild or moderate to severe asthma. METHODS Retrospective cross sectional design. Children diagnosed with ILO (N = 70), chronic non-specific cough (N = 70), mild asthma (N = 60), or moderate to severe asthma (N = 60) were identified from the electronic medical record of a large children's hospital. Spirometry was completed before ILO, non-specific cough, or asthma diagnoses were made by pediatric laryngologists or pulmonologists. Spirometry was performed following American Thoracic Society guidelines and was interpreted by a pediatric pulmonologist. Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 Second (FEV1), FEV1/FVC Ratio (FEV1/FVC), Forced Mid-Expiratory Flow 25--75 % (FEF25-75%), pulmonologist interpretation of flow volume loops, and overall exam findings were extracted from the medical record. RESULTS Ninety seven percent of children with ILO or chronic non-specific cough presented with spirometry values within normative range. Patients with ILO, non-specific cough, and mild asthma presented with FVC, FEV1, FEV1/FVC, and FEF25-75% values in statistically similar range. Children with moderate to severe asthma presented with significantly reduced FVC (p < .001), FEV1 (p < .001), FEV1/FVC (p < .001), and FEF25-75% (p < .001) values when compared with patients in the other groups. Flow volume loops were predominantly normal for children with ILO and non-specific cough. CONCLUSIONS Findings indicate that ILO and chronic non-specific cough can neither be diagnosed nor differentiated from mild asthma using spirometry alone. Spirometry should therefore be used judiciously with this population, bearing in mind the limitations of the procedure. Future research should determine the most effective and efficient ways of delineating ILO and non-specific cough from other respiratory conditions in children.

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
BACKGROUND Asthma and vocal cord dysfunction (VCD), also known as inducible laryngeal obstruction (ILO), may coexist, resulting in worse outcomes for patients. The experience of people with VCD/ILO and coexisting asthma is unknown. OBJECTIVE We sought to determine whether coexistent VCD/ILO and asthma have deleterious impacts on quality of life. METHODS We undertook a descriptive qualitative study using one-to-one semistructured interviews with 30 purposively recruited adult participants with a prior confirmed doctor asthma diagnosis and laryngoscopy-confirmed VCD/ILO. A thematic and content analysis was conducted to explore the data. RESULTS Participants were mostly female (63%), mean ± SD age 63 ± 12 years. Four themes were identified: trapped voice, altered life, knowledge about VCD/ILO, and looking for solutions. Participants reported their voice being trapped in their throat or the voice being suddenly cut off when talking or singing. Self-reported VCD/ILO symptoms including throat tightness and breathlessness were highlighted by participants. The second theme described how patients struggle to communicate or tended to shorten conversations. Insufficient knowledge and existing confusion regarding whether asthma was causing the breathlessness was described in the third theme. Looking for solutions depicted participants' diagnostic journey and how they sought an explanation for the symptoms. CONCLUSIONS People with asthma and coexisting VCD/ILO experience a substantial burden affecting the quality of life. These data describe the impact on patients with coexisting conditions and should be used to increase clinician awareness of the experience of VCD/ILO from patients' perspectives to support a personalized approach to care.

Abstract
Vocal fold motion impairment (VFMI) is the inappropriate movement of the vocal folds during respiration, leading to vocal fold adduction and/or abduction problems and causing respiratory and vocal impairments. Neurodegenerative diseases (NDDs) are a wide range of disorders characterized by progressive loss of neurons and deposition of altered proteins in the brain and peripheral organs. VFMI may be unrecognized in patients with NDDs. VFMI in NDDs is caused by the following: laryngeal muscle weakness due to muscular atrophy, caused by brainstem and motor neuron degeneration in amyotrophic lateral sclerosis; hyperactivity of laryngeal adductors in Parkinson's disease; and varying degrees of laryngeal adductor hypertonia and abductor paralysis in multiple system atrophy. Management of VFMI depends on whether there is a presence of glottic insufficiency or insufficient glottic opening with/without severe dysphagia. VFMI treatment options for glottic insufficiency range from surgical interventions, including injection laryngoplasty and medialization thyroplasty, to behavioral therapies; for insufficient glottic opening, various options are available based on the severity and underlying cause of the condition, including continuous positive airway pressure therapy, botulinum toxin injection, tracheostomy, vocal fold surgery, or a combination of interventions. In this review, we outline the mechanisms, clinical features, and management of VFMI in NDDs and provide a guide for physicians who may encounter these clinical features in their patients. NDDs are always progressive; hence, timely evaluation, proper diagnosis, and appropriate management of the patient will greatly affect their vocal, respiratory, and swallowing functions as well as their quality of life.

Abstract
Hypoxaemia in the postanaesthesia care unit is common and the majority is caused by hypoventilation or upper airway obstruction due to the (residual) effects of anaesthetic and analgesic agents. We present a case of upper airway obstruction caused by vocal cord dysfunction, a less frequently occurring aetiology. The patient's case suggests a notable relationship between procedural laryngeal stimulus and the onset of symptoms. Approach to the diagnosis and flexible laryngoscopy to either rule-in or rule-out several relevant differentials are discussed.

Abstract
OBJECTIVE This study examined the number of therapy sessions required to sufficiently improve (exercise) induced laryngeal obstruction (EILO/ILO) symptoms for discharge. Factors predicting therapy duration were examined as was the likelihood of patients returning for additional therapy sessions following initial discharge. METHODS Retrospective observational cohort design. Data for 350 patients were gathered from the University of Wisconsin-Madison Voice and Swallow Clinics Outcome Database. Patients (>18 years of age) diagnosed with EILO/ILO received therapy from a Speech-Language Pathologist (SLP) and were successfully discharged. EILO/ILO treatment details, symptoms, triggers, medical comorbidities, and patient demographics were collected from initial evaluations and subsequent course of therapy. RESULTS Patients required an average of 3.59 (SD = 3.7) therapy sessions prior to discharge. A comorbid behavioral health diagnosis (p = .026), higher Vocal Handicap Index Score (p = .009) and reduced physical activity due to EILO/ILO symptoms (p = .032) were associated with increased therapy duration. Patients with ILO or EILO with secondary environmental triggers required significantly more sessions than those with exercise-induced symptoms (p < .01). Eight percent of patients returned for additional sessions following discharge. Patients returning for additional sessions all came from affluent neighborhoods as measured by the Area Deprivation Index (ADI). CONCLUSIONS Patients with EILO/ILO required an average of 3.59 therapy sessions prior to discharge. As such, 4 sessions is a reasonable estimate for clinicians to provide patients. Six sessions may be a more conservative estimate for patients who present with a behavioral health diagnosis, a voice complaint, or reduced physical activity from EILO/ILO symptoms.

Abstract
Vocal cord dysfunction (VCD) is the inappropriate adduction of the vocal cords during inhalation and sometimes, exhalation. Vocal cord dysfunction is often misdiagnosed in the emergency room as asthma exacerbation or laryngeal angioedema, leading to unnecessary and potentially harmful interventions including intubation and mechanical ventilation. Based on this, it is especially important to recognize this condition early to avoid intubation, which can further worsen VCD. This case presents a 74-year-old female with a history of hypertension and colon cancer who presented to the emergency department (ED) with respiratory distress associated with stridor and wheezing. Our literature review sheds light on identifying key clinical features, physical exam findings, diagnostic tests, existing treatment options for this condition, and preventive measures to minimize its occurrence.

Abstract
The Spanish Guideline on the Management of Asthma, better known by its acronym in Spanish GEMA, has been available for more than 20 years. Twenty-one scientific societies or related groups both from Spain and internationally have participated in the preparation and development of the updated edition of GEMA, which in fact has been currently positioned as the reference guide on asthma in the Spanish language worldwide. Its objective is to prevent and improve the clinical situation of people with asthma by increasing the knowledge of healthcare professionals involved in their care. Its purpose is to convert scientific evidence into simple and easy-to-follow practical recommendations. Therefore, it is not a monograph that brings together all the scientific knowledge about the disease, but rather a brief document with the essentials, designed to be applied quickly in routine clinical practice. The guidelines are necessarily multidisciplinary, developed to be useful and an indispensable tool for physicians of different specialties, as well as nurses and pharmacists. Probably the most outstanding aspects of the guide are the recommendations to: establish the diagnosis of asthma using a sequential algorithm based on objective diagnostic tests; the follow-up of patients, preferably based on the strategy of achieving and maintaining control of the disease; treatment according to the level of severity of asthma, using six steps from least to greatest need of pharmaceutical drugs, and the treatment algorithm for the indication of biologics in patients with severe uncontrolled asthma based on phenotypes. And now, in addition to that, there is a novelty for easy use and follow-up through a computer application based on the chatbot-type conversational artificial intelligence (ia-GEMA).

Butler J, Asbridge H, Stringer H. Applying behaviour change theory to speech and language therapy intervention for inducible laryngeal obstruction. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2023; 58:1539-1550.

Abstract
BACKGROUND Speech and language therapists (SLTs) provide interventions for inducible laryngeal obstruction (ILO) despite a current lack of evidence to inform intervention delivery. This study is the first step to develop an evidence-based intervention for ILO, using behaviour change theory and the Behaviour Change Technique Taxonomy version 1 (BCTTv1). Outcomes will inform the early development stage of a complex speech and language therapy intervention for ILO, enabling more precise reporting of ILO intervention studies, as per CONSORT guidelines. AIMS (1) To identify whether the BCTTv1 is a useful tool for characterising speech and language therapy interventions for ILO, based on existing literature, current practice and patient interviews. (2) To identify key behaviour change techniques (BCT) used within existing complex speech and language therapy interventions for ILO METHODS AND PROCEDURES: A five-phase study was conducted: (1) a systematic literature search of six electronic databases (Medline, EMBASE, CINAHL (EBSCO), Scopus, Trip, Web of Science) and grey literature between 2008 and 2020; (2) observations of six speech and language therapy intervention sessions; (3) a semi-structured interview with an SLT to validate the observed BCTTs; (4) consensus from four national expert SLTs regarding application of synthesised BCTT data to their own experiences of ILO interventions; and (5) patient engagement to review and comment on findings. OUTCOMES AND RESULTS Forty-seven BCTs in total were coded across all three sources. Thirty-two BCTs were identified in clinical observations; 31 in interviews with SLTs and 18 in the literature. Only six BCT were identified in all three sources. Expert SLTs confirmed clinical application and relevance. Patients reported finding the concept of BCT challenging but highlighted the value of psychoeducation to support their understanding of symptoms and in turn to understand the rationale behind speech and language therapy intervention recommendations. CONCLUSION This study indicates that the BCTTv1 is a suitable framework to identify and describe intervention components used within speech and language therapy interventions for ILO. A practice-research gap exists, reinforcing that existing literature does not capture the complexity of speech and language therapy intervention for ILO. Further research is needed to develop our understanding of the BCTs that support optimal behaviour change for this patient group. WHAT THIS PAPER ADDS What is already known on the subject There is growing recognition for the value of speech and language therapists (SLTs) in delivering complex interventions for patients with inducible laryngeal obstruction (ILO), including evidence to suggest that their intervention can improve quality of life for patients and reduce excessive healthcare use. There are, however, no randomised controlled trials in this field; thus it is unclear what constitutes the most effective intervention. What this study adds This study demonstrates the complexity of speech and language therapy interventions for ILO and highlights the practice-research gap. It identifies a range of behaviour change techniques that are used in existing practice and captures patient views relating to the components identified within this study. What are the clinical implications of this work? Findings highlight the value of providing education about factors that might be driving ILO symptoms and in turn the importance of sharing with patients the rationale for treatment recommendations that necessitate a change in their behaviours. Identified behaviour change techniques can be used when developing and implementing SLT interventions for ILO.

Abstract
Inducible laryngeal obstruction (ILO), formerly referred to as paradoxical vocal fold motion and vocal cord dysfunction, is a complex disorder of the upper airway that requires skillful differential diagnosis. There are several medical conditions that may mimic ILO (or which ILO may mimic) that should be considered in the differential diagnosis before evidence-supported behavioral intervention is initiated to mitigate or eliminate this upper airway condition. A key in treatment planning is determination of an isolated presentation of ILO or ILO concurrent with other conditions that affect the upper airway. Accurate, timely differential diagnosis in the clinical assessment of this condition mitigates delay of targeted symptom relief and/or insufficient intervention. Accurate assessment and nuanced clinical counseling are necessary to untangle concurrent, competing conditions in a single patient. This tutorial describes the common and rare mimics that may be encountered by medical professionals who evaluate and treat ILO, with particular attention to the role of the speech-language pathologist. Speech-language pathologists receive referrals for ILO from several different medical specialists (allergy, pulmonology, and sports medicine), sometimes without a comprehensive team assessment. It is paramount that speech-language pathologists who assess and treat this disorder have a solid understanding of the conditions that may mimic ILO. Summary tables that delineate differential diagnosis considerations for airway noise, origin of noise, symptoms, triggers, role of the speech-language pathologist, and β-agonist response are included for clinician reference. A clinical checklist is also provided to aid clinicians in the critical assessment process.

Paradoxical vocal fold motion disorder (PVFMD) is a condition involving the inappropriate narrowing of the larynx with symptoms of laryngeal tightness and dyspnea. A 23-year-old woman was diagnosed with PVFMD by imaging, revealing dynamically constricted, supraglottic tissue, an abnormal adduction of the vocal cords with a characteristic "posterior chink" observed. After diagnosis, laryngeal control retraining protocols and biofeedback therapy were initiated. To treat persistent symptoms, interventions such as vocal fold botulinum toxin (BoNT) injections were performed with slight improvements. Ultimately, psychiatry performed 10 repetitive transcranial magnetic stimulations (rTMS) with a right-sided, low-frequency approach to treat the patient's underlying major depressive disorder and comorbid anxious distress. Afterward, the patient's symptoms were successfully reduced with an improvement in Dyspnea Severity Index. Although most patients with PVFMD were relieved with laryngeal control therapy, some are refractory and lack the literature on the best treatment. In this case, we followed the multidisciplinary approach and individualized our novel therapeutic strategies including especially rTMS, which successfully reduced symptoms. This is the first reported case of refractory PVFMD to be treated with novel interventions, and rTMS might play a role in PVFMD mitigation.

Abstract
PURPOSE Paradoxical Vocal Fold Movement (PVFM) may cause airway restriction and resulting dyspnea in the pediatric population. Therapy with a speech-language pathologist (SLP) is the primary treatment for children and adolescents diagnosed with Paradoxical Vocal Fold Movement (PVFM). This study examined treatment duration and factors predicting number of therapy sessions required. METHODS Data were drawn from the University of Wisconsin-Madison Voice and Swallow Clinics Outcome Database. One hundred and twelve children and adolescents were included in this study. Participants were diagnosed with PVFM, followed for therapy with a SLP, and were subsequently discharged from therapy with successful outcomes. Extracted data included number of therapy sessions, PVFM symptoms, patient demographics, medical history, and comorbid diagnoses. Regression was used to determine factors predicting therapy duration. RESULTS Patients completed an average of 3.4 therapy sessions before discharge. Comorbid behavioral health diagnosis (β = 1.96, t = 3.83, p < .01) and a history of upper airway surgeries (β = 1.26, t = 2.615, p = .01) were significant predictors of the number of therapy sessions required before discharge; both factors significantly increased therapy duration. Age, symptom trigger-type, reflux symptoms, and dysphonia did not predict therapy duration. Overall, our regression model accounted for 42% of the variance in number of sessions required (r2 = 0.42). CONCLUSIONS On average, 3.4 sessions of therapy with an SLP resolved PVFM symptoms. Children with a behavioral health diagnosis required an average of 5.45 sessions and those with a history of upper airway surgery an average of 4.3 sessions. Future work should examine the relationship between behavioral health care and PVFM treatment, as well as how PVFM treatment efficiency can be maximized.

Abstract
Objectives Paradoxical vocal fold motion (PVFM) is a common condition where the vocal folds inappropriately adduct during inspiration. This results in dyspnea and occasionally significant distress. The condition is thought to be primarily functional, with behavioural therapy considered mainstay in the non-acute setting. However, practice variations and limited access to speech language pathology (SLP) services can pose management challenges. We aimed to examine the efficacy of surgeon performed visual biofeedback as first-line treatment for PVFM. Study design Prospective, non-randomized, non-comparative clinical study. Methods Adult patients referred for possible PVFM and congruent laryngoscopy findings over a two-year period were included. Patients were excluded if they presented in acute distress, had alternate diagnosis to explain symptomology and/or coexisting untreated lower respiratory pathology. Patients underwent immediate surgeon-performed visual biofeedback on the same visit day. The primary outcome of interest was change in Dyspnea Index (DI) scores pre- and post-intervention 3 months follow-up. The secondary outcome measured was change in asthma medication use from baseline to follow-up. Results Of 34 patients presenting, 25 met inclusion criteria. Of these, 72% were female with an average age of 36.9 ± 14.1. Approximately 48% of patients had a diagnosis of well-controlled asthma at presentation and co-morbid psychiatric diagnoses were common (52%). Pre- and post-intervention analysis showed significant improvement in DI scores (p < 0.001) and reduction in bronchodilator use (p = 0.003). Conclusion This is a prospective study that evaluates the role of visual biofeedback in PVFM patients. Our data suggests that visual biofeedback effectively reduces short-term subjective symptoms and asthma medication use. Level of evidence 3 Graphical abstract ![]()

Abstract
Purpose The larynx is a uniquely situated organ, juxtaposed between the gastrointestinal and respiratory tracts, and endures considerable immunological challenges while providing reflexogenic responses via putative mucosal mechanoreceptor afferents. Laryngeal afferents mediate precise monitoring of sensory events by relay to the internal branch of the superior laryngeal nerve (iSLN). Exposure to a variety of stimuli (e.g., mechanical, chemical, thermal) at the mucosa-airway interface has likely evolved a diverse array of specialized sensory afferents for rapid laryngeal control. Accordingly, mucosal mechanoreceptors in demarcated laryngeal territories have been hypothesized as primary sources of sensory input. The purpose of this article is to provide a tutorial on current evidence for laryngeal afferent receptors in mucosa, the role of mechano-gated ion channels within airway epithelia and mechanisms for mechanoreceptors implicated in laryngeal health and disease. Method An overview was conducted on the distribution and identity of iSLN-mediated afferent receptors in the larynx, with specific focus on mechanoreceptors and their functional roles in airway mucosa. Results/Conclusions Laryngeal somatosensation at the cell and molecular level is still largely unexplored. This tutorial consolidates various animal and human researches, with translational emphasis provided for the importance of mucosal mechanoreceptors to normal and abnormal laryngeal function. Information presented in this tutorial has relevance to both clinical and research arenas. Improved understanding of iSLN innervation and corresponding mechanotransduction events will help shed light upon a variety of pathological reflex responses, including persistent cough, dysphonia, and laryngospasm.

Abstract
OBJECTIVE Dysfunctional breathing often coexists with asthma and complicates asthma control, especially in difficult-to-treat asthma. Voice bubbling therapy (VBT) by a specialized speech therapist may influence the breathing pattern. This pilot study investigated the effect of voice bubbling therapy (VBT) in participants with difficult-to-treat asthma, who fulfilled criteria for dysfunctional breathing pattern. METHOD Twenty-four patients were randomized between VBT and usual care (UC). VBT is blowing into a glass (resonance) tube (28 cm in length, 0.9 cm inner diameter) which ends in a bowl of water (1.5 litre). Lung function, capillary blood gas and questionnaires were measured at baseline, at 6 and 18 weeks of follow up. RESULTS No difference in ACQ and quality of life was found after VBT compared to UC group. However, after six weeks of bubbling therapy, pCO2 levels measured in capillary blood gas were higher (baseline median (IQR) pCO2 = 33.00 (17.25 - 38.6) mmHg; week 6 pCO2 = 36.00 (29.00 - 42.3) mmHg) p = 0.01. Moreover, ΔpCO2 (baseline - 18 weeks of follow up) was significantly correlated with ΔAQLQ (rs = 0.78, p = 0.02). CONCLUSION VBT in participants with difficult-to-treat asthma resulted in a higher average pCO2 level, indicating the treatment may improve hyperventilation. However, this did not improve asthma control or quality of life. VBT may have value for a better management of asthma related symptoms.

Abstract
Background In recent years, we have observed respiratory difficulty manifested as paroxysmal laryngospasm in a few outpatients, most of whom were first encountered in a respiratory clinic. We therefore explored how to identify and address paroxysmal laryngospasm from the perspective of respiratory physicians. Methods The symptoms, characteristics, auxiliary examination results, treatment, and prognosis of 12 patients with paroxysmal laryngospasm treated in our hospital from June 2017 to October 2019 were analyzed. Results Five males (42%) and 7 females (58%) were among the 12 Han patients sampled. The average age of the patients was 49.25 ± 13.02 years. The disease course ranged from 14 days to 8 years and was characterized by sudden dyspnea, an inability to inhale and exhale, a sense of asphyxia, and voice loss during an attack. Eight patients with gastroesophageal reflux were cured after antacid treatment. One case of upper respiratory tract infection (URI) was completely relieved after symptomatic treatment. One patient with left vocal cord paralysis experienced complete relief after specialist treatment by an otorhinolaryngologist. Episodes in 1 patient were significantly reduced after lifestyle improvement. One patient experienced spontaneous relief after rejecting treatment. Conclusions Paroxysmal laryngospasm is a rare laryngeal disease that generally occurs secondary to gastroesophageal reflux disease (GERD), and antireflux therapy is frequently effective for its treatment. A respiratory physician should master and identify the symptoms and differentiate this condition from hysterical stridor, reflux-related laryngospasm, and asthma. Timely referral to otolaryngologists, gastroenterologists, and other specialists for standardized examination and regular treatment should be provided when necessary.

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
OBJECTIVES To perform a systematic literature review on the use of Heliox with patients with inducible laryngeal obstruction/vocal cord dysfunction to: i) identify current evidence base; and ii) establish the methodological quality of published research. METHODS Articles published up to March 2018 were searched for key words and terms using Cochrane Library, MEDLINE, PubMed, CINAHL, EMBASE and Dynamed. Studies were included if they presented original research into the use of Heliox for vocal cord dysfunction. RESULTS Only three studies met the inclusion criteria for review. All reported favorable results for the use of Heliox as an adjunctive therapy for vocal cord dysfunction but none had sufficient methodological quality to support their conclusions. CONCLUSION Despite review articles recommending the use of Heliox in vocal cord dysfunction, there is a lack of good quality research to support this conclusion. There is a need for further research to investigate the effectiveness of Heliox as an adjunctive therapy for vocal cord dysfunction. LEVEL OF EVIDENCE 4.

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
Ear, nose and throat (ENT) comorbidities are common in patients with asthma and are frequently associated with poorer asthma outcomes. All these comorbidities are "treatable traits" in asthma. Identification and management of these disorders may spare medication usage and contribute to improved asthma control and quality of life, and a decrease in exacerbation rates.This review summarises recent data about the prevalence, clinical impact and treatment effects of ENT comorbidities in asthma including allergic rhinitis, chronic rhinosinusitis with and without nasal polyposis, aspirin-exacerbated respiratory disease, obstructive sleep apnoea and vocal cord dysfunction.Many of these comorbidities are possible to be managed by the pulmonologist, but the collaboration with the ENT specialist is essential for patients with chronic rhinosinusitis or vocal cord dysfunction. Further rigorous research is needed to study the efficacy of comorbidity treatment to improve asthma outcomes, in particular with the development of biotherapies in severe asthma that can also be beneficial in some ENT diseases.

Abstract
Vocal cord dysfunction, also known as paradoxical vocal fold motion (PVFM), is a disorder characterized by abnormal vocal cord adduction during inspiration. PVFM is commonly misdiagnosed as asthma because of the similarity of symptoms: cough, wheezing, chest pain, and dyspnea. We present the clinical vignette of a 36-year-old woman with juvenile rheumatoid arthritis and multiple adverse drug reactions who presented with recurrent episodes of unrecognized PVFM during skin testing for drug allergy, omalizumab treatment, and tocilizumab desensitization. Before the diagnosis of PVFM, these episodes were treated as anaphylaxis, including the administration of epinephrine. Once diagnosed and treated for PVFM, the patient did not present any further events and continued treatment for drug allergy. PVFM may be underreported in hypersensitivity reactions because of the similarity to Type 1-mediated respiratory symptoms and comorbid asthma.

Clinical Mimics: An Emergency Medicine-Focused Review of Asthma Mimics. J Emerg Med 2017; 53:195-201. [PMID: 28233608 DOI: 10.1016/j.jemermed.2017.01.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2016] [Revised: 01/02/2017] [Accepted: 01/04/2017] [Indexed: 11/22/2022]
Abstract
BACKGROUND Asthma is a common diagnosis or preexisting condition, and many patients with acute asthma exacerbation may present to the emergency department with wheezing and respiratory distress. However, many conditions may mimic this presentation. OBJECTIVES This review provides an overview of common asthma mimics and an approach to evaluation and management. DISCUSSION Asthma is characterized by an obstructive pulmonary disease with recurrent exacerbations. The disease may present with a variety of symptoms, including wheezing, chest tightness, shortness of breath, and even respiratory failure. Mimics include anaphylaxis, angioedema, central airway obstruction, heart failure, allergic reaction, foreign body aspiration, pulmonary embolism, and vocal cord dysfunction. The approach to evaluation and management of these patients includes assessment for life-threatening conditions while treatment and resuscitation is underway. Providers should assess for red flags, including no history of asthma, lack of severe asthma, and no improvement with standard treatments. Focused assessment with history, physical examination, chest imaging, electrocardiogram, and laboratory studies may provide benefit. Through consideration of these mimics and treatment, providers can provide rapid management. CONCLUSIONS While asthma is a common disease, many asthma mimics exist. Through consideration of other diseases with wheezing and assessing for red flags, such as patients presenting without a history of asthma or patients with a history of only mild asthma presenting with severe symptoms, emergency providers may decrease the chance of early diagnostic closure and anchoring while improving the care of these patients.
