Abstract
Post-anesthesia stridor due to laryngospasm, laryngeal edema, or any other organic cause is a life-threatening condition requiring immediate intervention. The very rare functional stridor or psychogenic stridor following emergence from general anesthesia may sometimes mimic stridor due to an organic cause, but it is neither fatal nor require immediate airway management. However, if the condition is not diagnosed timely, it may lead to unnecessary manipulation of the airway, such as endotracheal intubation or tracheostomy. We report herein a case of functional stridor in a 48-year-old woman who underwent abdominal-perineal resection for carcinoma rectum. The case was timely diagnosed by the attending anesthetist, and the patient recovered spontaneously, thus avoiding any unindicated airway handling and its associated complications.

Abstract
INTRODUCTION Exercise-induced laryngeal obstruction (EILO) and exercise-induced asthma can cause troublesome respiratory symptoms that can be difficult to distinguish between. Further, there is now a growing appreciation that the two conditions may coexist, complicating the interpretation of symptoms. The primary aim of this study is to investigate the prevalence of EILO in patients with asthma. Secondary aims include evaluation of EILO treatment effects and investigation of comorbid conditions other than EILO in patients with asthma. METHODS AND ANALYSIS The study will be conducted at Haukeland University Hospital and Voss Hospital in Western Norway, and enrol 80-120 patients with asthma and a control group of 40 patients without asthma. Recruitment started in November 2020, and data sampling will continue until March 2024. Laryngeal function will be assessed at baseline and at a 1-year follow-up, using continuous laryngoscopy during high-intensity exercise (CLE). Immediately after the EILO diagnosis is verified, patients will be treated with standardised breathing advice guided by visual biofeedback from the laryngoscope video screen. The primary outcome will be the prevalence of EILO in patients with asthma and control participants. Secondary outcomes include changes in CLE scores, asthma-related quality of life, asthma control and number of the asthma exacerbations, as assessed between baseline and the 1-year follow-up. ETHICS AND DISSEMINATION Ethical approval has been obtained from the Regional Committee for Medical and Health Research Ethics, Western Norway, (ID number 97615). All participants will provide signed informed consent before enrolment. The results will be presented in international journals and conferences. TRIAL REGISTRATION NUMBER NCT04593394.

Abstract
BACKGROUND Vocal cord dysfunction is an upper-airway disorder characterized by exaggerated and transient glottic constriction causing respiratory and laryngeal symptoms. Common presentation is with inspiratory stridor often in the context of emotional stress and anxiety. Other symptoms include wheezing (which may be on inspiration), frequent cough, choking sensation, or throat and chest tightness. This is seen commonly in teenagers, particularly in adolescent females. The COVID-19 pandemic has been a trigger for anxiety and stress with an increase in psychosomatic illness. Our objective was to find out if the incidence of vocal cord dysfunction increased during COVID-19 pandemic. METHODS We performed a retrospective chart review of all the subjects with a new diagnosis of vocal cord dysfunction who were seen at the out-patient pulmonary practice at our children's hospital between January 2019-December 2020. RESULTS The incidence of vocal cord dysfunction in 2019 was found to be 5.2%, (41/786 subjects seen) compared to 10.3% (47/457 subjects seen) in 2020, which is a nearly 100% increase in incidence (P < .001). CONCLUSIONS It is important to recognize that vocal cord dysfunction has increased during the COVID-19 pandemic. In particular, physicians treating pediatric patients, as well as respiratory therapists, should be aware of this diagnosis. It is imperative to avoid unnecessary intubations and treatments with bronchodilators and corticosteroids as opposed to behavioral and speech training to learn effective voluntary control over the muscles of inspiration and the vocal cords.

Abstract
Inducible laryngeal obstruction (ILO) describes as inappropriate, episodic, reversible laryngeal closure during inspiration, occurring at the glottic and/or supraglottic level, in response to external triggers causing exertional breathing difficulties. We describe a case of a female patient with an underlying major depressive disorder who presented with sudden onset of stridor and tachypnoea, whereby the external trigger was psychogenic in origin. Bedside flexible nasopharyngolaryngoscopy (FNPLS) showed characteristic findings of paradoxical adduction of vocal cords during inspiration. Arterial blood gas analysis, routine blood tests, chest radiography, and computed tomography (CT) scan of brain, neck, and thorax excluded neurological or airway abnormality. Bedside distraction breathing exercise alleviated the stridor and tachypnoea. The patient was managed by supportive psychotherapy, speech therapy, and anti-reflux medication and was discharged well with resolution of her respiratory distress. We would like to highlight that meticulous history along with physical examinations are imperative especially amongst Otorhinolaryngologists as emergent airway management tracheostomy would have been unnecessary and cause more stress and burden to the patient as well as family members.

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
ZusammenfassungWiederholt episodenhaft auftretende Atemnot ist im Kindes- und Jugendalter ein häufiges Symptom. Neben anstrengungsinduzierter Bronchialobstruktion im Rahmen eines Asthma bronchiale ist eine funktionelle Genese eine sehr häufige Differenzialdiagnose. Dennoch wird diese Diagnose häufig nicht oder mit langer Latenz gestellt. Unter dem Oberbegriff „ILO“ („inducible laryngeal obstruction“) werden sowohl funktionelle supraglottische Obstruktionen durch Kollaps der Knorpelstrukturen als auch Dysfunktionen auf Glottisebene wie „vocal cord dysfunction“ (VCD) subsumiert. Körperliche Anstrengung ist ein häufiger Auslöser; es werden jedoch auch Beschwerdebilder ohne Anstrengungsbezug beobachtet. Es wird der Erkenntnisstand zur Pathophysiologie referiert und die klinische Präsentation beschrieben. Ein wesentlicher Fokus des Artikels liegt im Folgenden auf der Darstellung eines sinnvollen und Ressourcen-orientierten diagnostischen Vorgehens. Der CLE-Test („continuous laryngoscopy exercise test“) als Provokationsmethode unter Wach-Videolaryngoskopie ist der Goldstandard, jedoch wird diese Diagnostik im deutschsprachigen Raum nicht flächendeckend vorgehalten. Dieses Positionspapier stellt daher die diagnostische Wertigkeit verschiedener anderer Diagnostik-Algorithmen und anamnestischer Informationen heraus. Ein weiterer Schwerpunkt des Papiers besteht in der detaillierten Vorstellung geeigneter atemphysiotherapeutischer Interventionen.

Abstract
OBJECTIVE To determine whether treatment effectiveness can be established for a range of vocal cord dysfunction (VCD) interventions in adolescents and adults. DESIGN A systematic review of the literature and risk of bias appraisal was completed using the Joanna Briggs Institute Critical Appraisal Tools. Data were qualitatively synthesized in the broad intervention groups of glottic airway and respiratory retraining, pharmacological therapies, airway device therapies and psychological therapies. DATA SOURCES Nine electronic databases, two clinical trial registries and the grey literature were searched from inception to September 2021 for articles on VCD interventions or equivalent terms. ELIGIBILITY CRITERIA Studies were included if they were randomized controlled trials, non-randomized controlled trials, quasi-experimental pre- and post-test studies and within-subject repeated measure designs, participants were 13 years or older, VCD was diagnosed using laryngoscopy or CT larynx, VCD intervention was provided and outcome measures reported on VCD symptoms. RESULTS The search yielded no randomized controlled trials. There were 17 quasi-experimental studies that met the eligibility criteria, and these studies reported on glottic airway and respiratory retraining, botulinum toxin injections, inspiratory muscle strength training and amitriptyline; all were associated with VCD symptom reduction. In addition, 2 within-subject repeated measure studies reported inspiratory muscle strength training and respiratory retraining to be effective in reducing symptoms in participants with exertional VCD. The included studies were reported in full-text publications (11) and conference proceedings (8). There was a high risk of bias and low quality of evidence across all intervention areas. CONCLUSION Glottic airway and respiratory retraining, botulinum toxin injections, low-dose amitriptyline and inspiratory muscle strength training devices have been associated with symptom reduction in adults and adolescents with vocal cord dysfunction. Limited objective data exist to support the effectiveness of these interventions, and robust controlled trials are needed in this area. Systematic Review Registration: CRD42018092274 (PROSPERO).

Abstract
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. Validated questionnaires were used to assess general self-rated health, subjective health complaints (Health Behavior in School-aged Children-Symptom Check List; HBSC-SCL), general self-efficacy (GSE), and anxiety symptoms (SCARED). The outcomes were compared with normative data from comparable unselected populations. Results: The HBSC-SCL items for somatic complaints revealed weekly or more often occurrence of headache in 42%, abdominal pain in 30%, backache in 31%, and dizziness in 32%. For psychological complaints, corresponding figures were 26% for feeling low, 43% for irritability or bad mood, 33% for feeling nervous, and 38% for sleep problems. Mean (range) GSE score was 3.13 (2.2-4.0), and reports suggesting anxiety symptoms were rare. The outcomes were in line with normative data from comparable unselected populations. Self-rated health, and scores obtained for HBSC-SCL, GSE, and SCARED were similarly distributed across EILO subtypes and severity. Conclusion: Self-reported health, self-efficacy, and level of anxiety symptoms in adolescents with laryngoscopically confirmed EILO were similar to data obtained in comparable unselected populations, irrespective of EILO subtype and severity. The findings challenge the notion that pediatric EILO is causally related to psychological problems.

Abstract
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. EILO can therefore remain misdiagnosed for years, and most patients receive inappropriate asthma therapy. In contrast with asthma, EILO symptoms are usually most prominent at maximal exercise intensity and resolve quickly on exercise cessation. It is important to recognize that EILO and asthma can coexist in a proportion of athletes. The criterion standard test for diagnosing EILO is continuous laryngoscopy during exercise testing, although eucapnic voluntary hyperpnea testing has also been used. Various surgical or pharmacological interventions can be used to treat EILO, but first-line treatment is breathing technique work. Further research is needed to establish the optimal treatment algorithm, and more work is needed to increase awareness of this important clinical entity.

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
Dynamic obstructions of the larynx are a set of disorders that occur during exercise in equines and humans. There are a number of similarities in presentation, diagnosis, pathophysiology and treatment. Both equines and humans present with exercise intolerance secondary to dyspnea. During laryngoscopy at rest, the larynx appears to function normally. Abnormalities are only revealed during laryngoscopy at exercise, seemingly triggered by increased ventilatory demands, and quickly resolve after cessation of exercise. Lower airway disease (asthma being the most prevalent condition), cardiac disease and lack of fitness are the major differentials in both species. Laryngoscopic examination during exercise should be performed from rest to peak exertion to allow for a comprehensive diagnosis, including where the airway collapse begins, and thereafter how it progresses. Dynamic disorders with most visual similarity between humans and equines are: aryepiglottic fold collapse (both species); equine dynamic laryngeal collapse (DLC) relative to some forms of human combined supraglottic/glottic collapse; and epiglottic retroversion (both species). Quantitative grading techniques, such as airway pressure measurement, that have proven effective in veterinary research are currently being piloted in human studies. Conditions that appear visually similar are treated in comparable ways. The similarities of anatomy and certain types of dynamic collapse would suggest that the equine larynx provides a good model for human upper respiratory tract obstruction during exercise. Thus, close collaboration between veterinarians and medical personal may lead to further advancements in understanding pathophysiologic processes, and enhance the development of improved diagnostic tests and treatments that will benefit both species.

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
Introduction
Vocal cord dysfunction is characterized by unintentional paradoxical vocal cord movement resulting in abnormal inappropriate adduction, especially during inspiration; this predominantly manifests as unresponsive asthma or unexplained stridor. It is prudent to be well informed about the condition, since the primary presentation may mask other airway disorders.
Objective
This descriptive study was intended to analyze presentations of vocal cord dysfunction in a tertiary care referral hospital. The current understanding regarding the pathophysiology and management of the condition were also explored.
Methods
A total of 27 patients diagnosed with vocal cord dysfunction were analyzed based on demographic characteristics, presentations, associations and examination findings. The mechanism of causation, etiological factors implicated, diagnostic considerations and treatment options were evaluated by analysis of the current literature.
Results
There was a strong female predilection noted among the study population (
n
= 27), which had a mean age of 31. The most common presentations were stridor (44%) and refractory asthma (41%). Laryngopharyngeal reflux disease was the most common association in the majority (66%) of the patients, with a strong overlay of anxiety, demonstrable in 48% of the patients.
Conclusion
Being aware of the condition is key to avoid misdiagnosis in vocal cord dysfunction. Fiberoptic laryngoscopy is the diagnostic gold standard to demonstrate paradoxical vocal cord adduction during an attack. A multidisciplinary approach should be adapted for the management, which should be specific and tailored for individual patients.

Abstract
Asthma is a heterogeneous disease, usually characterized by chronic airway inflammation. Various clinical conditions can mimic asthma, such as foreign body aspiration, subglottic stenosis, congestive heart failure, diffuse panbronchiolitis, aortic arch anomalies, reactive airway dysfunction syndrome, chronic obstructive pulmonary disease, retrosternal goiter, vocal cord tumors, other airway tumors, and vocal cord dysfunction. Upper airway obstruction can be a life-threatening emergency. Here, we present the case of a 58-year-old female with recurrent hospital visits for wheezing and exacerbations of asthma, who was later found to have a vocal cord nodule confirmed to be squamous cell carcinoma, which was mimicking like asthma.

Abstract
OBJECTIVES Paradoxical vocal fold motion (PVFM) consists of intermittent adduction of the vocal folds during inspiration, resulting in stridor and worsened by anxiety and stress. The purpose of this study was to assess the impact of PVFM on quality of life in our pediatric patient population. STUDY DESIGN This is a prospective, descriptive survey study. METHODS Thirty-nine consecutive patients (ages 12-17 years) presenting with a PVFM diagnosis for respiratory retraining sessions with speech-language pathology were recruited. Patients completed a brief demographic questionnaire and the Short Form 36, version 2, a validated tool for measuring health-related quality of life. RESULTS There were 31 (79%) girls and 8 (21%) boys with a mean age of 15.5 years. Subjects reported regular participation in competitive extracurricular activities, including track or cross country (30.8%), swimming (17.9%), and cheerleading or dancing (15.4%). Of the patients in the study, 46.2% were straight-A students. On the SF-36 (population averages normalized to a score of 50), the general health of patients with PVFM was better than that of the general population (53.27); however, their physical health limited their role activities more severely (42.82). In addition, a greater proportion of the group with PVFM was at risk for first-stage depression screening when compared with the general population (28% versus 18%). CONCLUSIONS We demonstrate a measurable detrimental impact of PVFM on health-related quality of life. This is consistent with previously published literature showing a preponderance of females with PVFM, most of whom are high achievers academically and athletically.

Abstract
OBJECTIVES Goals of the current study were to (1) conduct initial validation of a new Paradoxical Vocal Fold Movement Disorder Screening Questionnaire (PVFMD-SQ); (2) determine if symptom-based questionnaires can discriminate between patients with confirmed PVFMD and those with diagnosed uncontrolled asthma without clinical suspicion for PVFMD; and (3) determine if a new questionnaire with diagnostic specificity could be created from a combination of significant items on previously validated questionnaires. METHODS This is a prospective, case-controlled study of patients with PVFMD only and asthma only, who completed five questionnaires: Dyspnea Index, Reflux Symptom Index, Voice Handicap Index-10, Sino-Nasal Questionnaire, and PVFMD-SQ. Factor analysis was completed on the new PVFMD-SQ, and the discrimination ability of selected factors was assessed by receiver operating characteristics curve. The factor with the greatest discriminatory ability was selected to create one diagnostic questionnaire, and scores for each participant were calculated to estimate how well the factor correlated with a PVFMD or asthma diagnosis. Mean scores on all questionnaires were compared to test their discriminatory ability. RESULTS Patients with PVFMD showed greater voice handicap and reflux symptoms than patients with asthma. A 15-item one-factor questionnaire was developed from the original PVFMD-SQ, with a sensitivity of 89% and specificity of 73% for diagnosing asthma versus PVFMD. The combined questionnaires resulted in four factors, none of which showed discriminatory ability between PVFMD and asthma. CONCLUSION This study represents the first time that a patient symptom-based screening tool has shown diagnostic sensitivity to differentiate PVFMD from asthma in a cohort of symptomatic patients.

Abstract
Coordination between the larynx and lower airways is essential for normal voice production. Dyscoordination may contribute to myriad voice problems. The current study provides an overview of respiratory and laryngeal physiology as it relates to normal and disordered voice production, as well as a review of phonatory aerodynamic assessment practices. Finally, the integration of voice and breathing in common voice therapy programs is explored.

Abstract
The study and management of episodic laryngeal breathing disorders (ELBD)—characterized by paradoxical laryngeal movement patterns and dyspnea—has traditionally focused on clinical presentation of these conditions. However, the underlying mechanisms driving these entities are largely unknown. This article provides a review of potential underlying mechanisms driving clinical expression in ELBD and suggests approaches to the future study of ELBD etiology.

Abstract
Exercise-induced shortness of breath is not uncommon in otherwise healthy young people. Based on the presenting symptoms alone, it is challenging to distinguish exercise-induced asthma (EIA) from exercise-induced obstruction of central airways, sometimes leading to diagnostic errors and inadequate treatment. Central airway obstruction usually presents with exercise-induced inspiratory symptoms (EIIS) during ongoing exercise. EIIS tends to peak towards the end of an exercise session or immediately after its completion, contradicting symptoms of EIA typically peaking 3-15 min after the exercise has stopped. EIIS is usually associated with some form of laryngeal obstruction. Transnasal flexible laryngoscopy performed continuously throughout an incremental exercise test from rest to exhaustion or to intolerable symptoms is usually diagnostic, and also provides information that is important for further handling and treatment. Reflecting the complex anatomy and functional features of the larynx, exercise-induced laryngeal obstruction (EILO) appears to be a heterogeneous condition. Contradicting previous beliefs, recent literature suggests that laryngeal adduction in a majority of cases starts in supraglottic structures and that vocal cord adduction (VCD) most often occurs as a secondary phenomenon. However, EILO is poorly understood and more and better research is needed to unravel causal mechanisms. The evidence base for treatment of EILO is weak. Speech therapy, psychotherapy, biofeedback, muscle training, anticholinergic aerosols have all been applied, as has laser supraglottoplasty. Randomized controlled trials with well-defined and verifiable inclusion and success criteria are required to establish evidence-based treatment schemes.

Abstract
PURPOSE In this article, our goal was to determine the state of the evidence and the effect of speech-language pathology (SLP) treatment for individuals with paradoxical vocal fold motion (PVFM). METHOD The American Speech-Language-Hearing Association's National Center for Evidence-Based Practice in Communication Disorders searched 22 electronic databases using key words related to PVFM, speech or voice treatment, and behavioral intervention for articles published through July 2013. Identified articles were systematically evaluated to assess the quality of the evidence using a modification of the American Speech-Language-Hearing Association's critical appraisal scheme. RESULTS Sixty-five articles met the search criteria. Only 2 out of the 65 articles were judged to contain adequate evidence to evaluate the effect of SLP treatment for PVFM. All 65 articles exemplify the state of the evidence for SLP treatment for PVFM. CONCLUSION The state of the evidence for the use of SLP treatment is in its infancy, with a majority of articles in the exploratory stage of research. Consequently, few clinical implications can be drawn at this time. SLP treatment for PVFM is promising; however, there is clearly a pressing need for systematic experimental studies that involve a control group to further the evidence base.

Abstract
BACKGROUND Vocal cord dysfunction (VCD) or paradoxical vocal-fold motion (PVFM) is a functional disorder of the vocal cords that requires multidisciplinary treatment. Besides relaxation techniques, the use of psychological interventions can help treat the underlying psychological co-morbidities. There is currently no literature that examines the effectiveness of psychological interventions for VCD/PVFM. OBJECTIVES To review the evidence for psychological interventions used for the treatment of patients with VCD/PVFM. DATA SOURCES We searched electronic databases for English medical literature using Pubmed (Medline), PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Registry of Controlled Trials, and Clinicaltrials.gov. The date range for our search is from June 1964 to June 2014. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS We included studies that reported the use of psychological interventions in both adults and children diagnosed with VCD/PVFM. We included randomized controlled trials, case-control studies, retrospective chart reviews, prospective case series, and individual case reports. RESULTS Most reported studies are small case series or individual case reports that have described the use of interventions such as psychotherapy, behavioral therapy, use of anti-anxiety and anti-depressant medications, and hypnotherapy in conjunction with breathing exercises taught by speech therapists for symptomatic relief. Among the various psychological interventions that have been reported, there is no data regarding effectiveness and/or superiority of one approach over another in either adult or pediatric patients. CONCLUSIONS Psychological interventions have a role to play in the management of adult and pediatric patients with VCD/PVFM. Future prospective studies using uniform approaches for treatment of associated psychopathology may help address this question.

Abstract
A 2 yr old castrated male cat presented to an emergency referral facility for several episodes of gagging, nonproductive coughing, and increased respiratory effort. He was diagnosed with inspiratory stridor and referred to another emergency referral practice for further diagnostics. Three separate, sedated oral examinations, nasal computed tomography (CT), rhinoscopic biopsies, and tracheoscopy showed no structural causes for the cat's stridor. An endotracheal wash was consistent with feline asthma. Blood work showed a peripheral eosinophilia and exposure to Dirofilaria immitis (D. immitis). The feline asthma was treated with albuterol, fluticasone, dexamethasone sodium phosphate, and terbutaline. Despite aggressive therapy for feline asthma, the cat had several episodes of severe inspiratory respiratory distress and stridor secondary to an upper airway obstruction. After 3 days of hospitalization, a temporary tracheostomy was performed and no further episodes of respiratory distress were noted. The tracheostomy tube was removed 3 days later, and the cat was discharged on the fourth day. At a 14 mo follow-up examination, the client reported no further episodes of respiratory distress, coughing, or gagging. To the authors' knowledge, this is the first report of dynamic upper airway obstruction secondary to feline asthma.

Abstract
Paradoxical vocal cord motion (PVCM), or vocal cord dysfunction, is a descriptive term for inappropriate adduction of the vocal folds during respiration. The laryngeal mistiming leads to breathing difficulty and is often misdiagnosed as refractory asthma. The etiology of PVCM has been unclear but has long been hypothesized to be psychological. The present thesis is a prospective study of 170 patients older than 18 years being evaluated for PVCM, with 117 of the 170 (68.8%) identified as having PVCM by video laryngoscopy. Laryngeal edema (P = .021) and reflux (P = .026) were increased in patients with PVCM. A flat inspiratory arm of the flow volume loop during spirometry testing was a predictor of PVCM (P = .034). A subgroup of 47 newly diagnosed patients with PVCM underwent psychological analysis. The psychological profiles were elucidated using the Minnesota Multiphasic Personality Inventory and the Life Experiences Survey to evaluate stress. Compared to established normative data, PVCM demonstrated a conversion disorder pattern (P < .01) but not an anxiety disorder or a correlation with stress. A subgroup, 11 of the 47 (23.4%), had normal psychological outcomes, and two of the 47 (4.3%) were identified as malingering. Previous studies have suggested that PVCM is strictly a psychological disorder. It is proposed that PVCM is a descriptive term that is multifactorial and the etiology should direct treatment. A classification scheme divides PVCM into primary, or psychological, and secondary. The secondary form consists of medical disorders divided into irritable larynx syndrome and neurologic disorders.

Abstract
OBJECTIVE We report a novel bilateral suture lateralisation technique that allowed permanent tracheostomy decannulation in a patient with severe paradoxical vocal fold movement. CASE REPORT A 45-year-old woman presented to the accident and emergency department with worsening shortness of breath. Flexible nasoendoscopy revealed limited vocal fold abduction and an emergency tracheostomy was sited; this was subsequently changed to a long-term Silver Negus tube. Her tracheostomy care was complicated by discomfort and dislodgement. The diagnosis of paradoxical vocal fold movement was only made when the patient presented to our department. Cognitive behaviour therapy and botulinum toxin injection were tried without success. A right vocal fold lateralisation procedure was performed, which enabled temporary tracheostomy decannulation. A left vocal fold lateralisation procedure was subsequently performed and the patient was successfully decannulated, with significant improvement in quality of life. CONCLUSION Paradoxical vocal fold movement is a rare condition that is most commonly managed by biofeedback sessions, relaxation manoeuvres or botulinum toxin injection. However, in cases similar to ours in which these treatments are unsuccessful, we suggest a 'last resort' technique to manage this rare condition.

Abstract
Wood and Milgrom defined vocal cord dysfunction (VCD) as paradoxical adduction of the vocal folds during inspiration or during inspiration and expiration. We describe the case of a patient with attacks of dyspnea with an isolated expiratory paradoxical adduction of the vocal folds. A review of the literature reveals many factors associated with VCD. Because of the similar risk factors and order of events concerning VCD, we believe that even expiratory laryngeal dysfunctions could be denoted as subtypes of VCD.

Abstract
OBJECTIVE The etiology of paradoxical vocal fold dysfunction (PVFD) has been unclear, but it has long been hypothesized that there is a significant psychological component. The purpose of this study was to elucidate the psychological profiles of patients newly diagnosed with PVFD using psychometrically-sound psychological assessment instruments. STUDY DESIGN Prospective cohort study of 45 adults newly diagnosed with PVFD at a tertiary university referral center. METHODS The Minnesota Multiphasic Personality Inventory (MMPI-2) was administered to test for psychopathology. The Life Experiences Survey (LES) was administered to investigate levels of stress. Demographic, medical, and social histories were reviewed. MMPI-2 and LES scores for the PVFD cohort were compared with scores previously established for normative populations. RESULTS The study population included 81% female and 60% who were age 50 or older. Compared to the normative population for the MMPI-2, significant differences were noted for both male and female PVFD patients; on average, scores were highly elevated on the hypochondriasis scale and hysteria scale and less elevated on the depression scale. This pattern was consistent with conversion disorder (P < .01). In MMPI-2 subset analysis, 18 patients had a classic conversion profile while 13 others had elevated scores in the three scales of interest, but not in the classic conversion disorder pattern. Also, 11 patients had normal scores, suggesting no psychopathology. PVFD patients with a psychological history scored significantly higher on the depression and anxiety scales than PVFD patients without a psychological history. Patients with a history of asthma or gastroesophageal reflux disease (GERD) achieved significantly higher scores on the hypochondriasis scale than those without that medical history. On the LES assessment, female PVFD patients had significantly lower levels of positive stress and higher levels of negative stress than the general population; total levels of stress were not significantly different, however. Male PVFD patients had significantly lower levels of positive, negative, and total stress. For the entire cohort, asthma (65%), GERD (51%), and a history of abuse (38%) were common comorbidities. CONCLUSIONS On average, in both male and female adults, PVFD is associated with conversion disorder, representing a physical manifestation of underlying psychological difficulty. There also appears to be a subset of PVFD that is not associated with psychopathology. PVFD patients with a previous psychological history are prone to more depressive and anxious symptomatology. Patients with PVFD and a history of asthma or GERD are more likely to excessively complain about physical symptoms. Overall levels of stress are not higher in PVFD patients compared to a general population. However, females report more negative stress, and both males and females may have trouble coping with the amount of stress that they do have. PVFD is more common among women, more prevalent among older individuals, and can be comorbid with asthma, GERD, and previous abuse. These results have implications for treatment- psychotherapy directed for somatoform and conversion disorders may be added to traditional speech therapy for increased efficacy.

The frequency of perceived stress, anxiety, and depression in patients with common pathologies affecting voice. J Voice 2008; 22:472-88. [PMID: 18395419 DOI: 10.1016/j.jvoice.2006.08.007] [Citation(s) in RCA: 115] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2006] [Accepted: 08/08/2006] [Indexed: 11/15/2022]
Abstract
The study's objectives were to investigate (1) the frequency of perceived stress, anxiety, and depression for patients with common voice disorders, (2) the distribution of these variables by diagnosis, and (3) the distribution of the variables by gender. Retrospective data were derived from self-report questionnaires assessing recent stress (Perceived Stress Scale-10), anxiety, and depression (Hospital Anxiety and Depression Scale) in a cohort of new patients presenting to a voice clinic. Data are presented on 160 patients with muscle tension dysphonia (MTD), benign vocal fold lesions, paradoxical vocal fold movement disorder (PVFMD), or glottal insufficiency. Pooled data indicated that average stress, anxiety, and depression scores were similar to those found for the healthy population. However, 25.0%, 36.9%, and 31.2% of patients showed elevated stress, anxiety, and depression scores, respectively, compared to norms. Patients with PVFMD had the most frequent occurrence-and patients with glottal insufficiency had the least frequent occurrence of elevated stress, anxiety, and depression. Stress and depression were more common with MTD than with lesions, whereas reverse results were obtained for anxiety. More females than males had elevated stress, anxiety, and depression scores. The data are consistent with suggestions that stress, anxiety, and depression may be common among some patients with PVFMD, MTD, and vocal fold lesions and more common for women than men. However, individual variability in the data set was large. Further studies should evaluate the specific role of these conditions for selected categories of voice disorders in susceptible individuals.

Abstract
BACKGROUND Vocal cord dysfunction (VCD) is an increasingly recognized condition that affects the upper airway, which can be difficult to discriminate from asthma. Speech therapy and psychological cognitive therapy are the mainstays of treatment, but other modalities have been used when response is unsatisfactory. OBJECTIVE To present 2 case studies in which VCD has been treated with long-term tracheostomy. METHODS In the first patient, VCD was diagnosed by nasoendoscopic demonstration of paradoxical movement of the vocal cords. The patient was transferred to a regional unit, where nasoendoscopy was performed, which revealed immobile and adducted vocal cords. The decision to perform emergency surgical tracheostomy was made. In the second patient, a possible additional diagnosis of VCD was suggested during a hospital stay, and nasoendoscopy was performed. RESULTS Both patients report considerable subjective benefits. Objective improvement was seen in only one patient. CONCLUSIONS Tracheostomy is an invasive procedure that carries risk of potential morbidity and should only be considered as a final option in carefully selected cases.

Abstract
We report a case of stridor in a 32 year old woman. Initial laryngoscopy demonstrated adduction of the vocal cords on inspiration, which reverted to abduction on induction of general anaesthesia. The airway was structurally normal. The most likely diagnosis was paradoxical vocal cord motion, a condition in which psychological stress can precipitate respiratory symptoms and signs due to involuntary adduction of the vocal cords during inspiration. Its importance to the anaesthetist lies in its ability to masquerade as a serious airway or respiratory condition.

Abstract
OBJECTIVE The purpose of this study was to determine whether methacholine challenge testing (MCT) combined with serial laryngoscopy could elicit and visualize paradoxical vocal fold motion (PVFM) during asymptomatic periods and suggest laryngeal dysfunction as an etiology of episodic dyspnea. STUDY DESIGN A retrospective study of seven adult patients. METHODS Medical records of seven adult patients who were referred to an otolaryngology clinic with recurrent episodes of dyspnea or choking and underwent bronchoprovocation testing were reviewed. After initial fiberoptic laryngoscopy and pulmonary function testing (PFT), bronchoprovocation was performed using aerosolized methacholine at increasing concentrations. Each administration was followed by repeated laryngoscopy and PFT. A positive endoscopic test was marked by the visualization of paradoxical adduction of the true vocal folds during inspiration. A positive bronchoprovocation test was marked by a 20% or greater decline in the forced expiratory volume. RESULTS All seven patients demonstrated normal upper airway anatomy and function on initial laryngoscopy. In three patients, a positive endoscopic examination demonstrating PVFM was elicited during MCT. In three, the bronchoprovocation test was positive, and asthma was diagnosed. In one patient, both tests were negative. PVFM was seen in all patients whose chief complaint was choking (n = 2) but in only one of five patients whose chief complaint was dyspnea. CONCLUSIONS PVFM may be elicited and observed during MCT coupled with serial laryngoscopy. This test holds promise in differentiating vocal cord dysfunction from asthma during asymptomatic periods in patients who present with recurrent episodes of refractory dyspnea.

Abstract
BACKGROUND Vocal cord dysfunction (VCD) is an involuntary functional disorder commonly misdiagnosed as asthma. Previous reports describe the disorder and treatment but not the long-term outcome. OBJECTIVE To determine the long-term outcome of VCD. METHODS A retrospective medical record review identified 49 patients, ages 8 to 25 years, diagnosed as having VCD from 1989 to 2002. Telephone contact was attempted in all. RESULTS Of the 49 patients, 41 had previously been treated for asthma; that diagnosis was confirmed by us as a comorbidity in only 12 patients. Two distinct phenotypes of VCD were observed. Symptoms were limited to exercise-induced VCD (EIVCD) in 29 and spontaneously occurring VCD (SVCD) in 20, only 4 of whom additionally had EIVCD. Twenty-eight of the 49 were successfully contacted by telephone. Eight of the 11 contacted patients with SVCD followed the recommendation to see our speech therapist, all of whom learned to control symptoms. However, 2 who also had EIVCD continued with that problem. Pretreatment with an anticholinergic inhaler prevented EIVCD in 6 patients in whom this was tried. Complete absence of symptoms, at times ranging from 1 week to 5 years (median, 5 months), was reported in 26 of the 28 contacted patients. CONCLUSIONS VCD continues to be frequently misdiagnosed as asthma. Two phenotypes of VCD are apparent: EIVCD and SVCD. Speech therapy provides relief of symptoms for SVCD. Prevention of EIVCD with an anticholinergic inhaler in 6 patients suggests that a controlled clinical trial is warranted. Regardless of treatment, eventual spontaneous resolution was common.
