Abstract
Objectives: We describe a cohort of patients with an unusual presentation of stridor, their evaluation and management, and their outcome. We review the pertinent English-language literature. Methods: We performed a retrospective review of the records of 12 adolescent patients treated for acute-onset inspiratory stridor at the Departments of Otolaryngology-Head and Neck Surgery and Allergy and Immunology at the University of South Florida and the Department of Speech Pathology at the H. Lee Moffitt Cancer Center and Research Institute. Two additional patients received treatment elsewhere. Demographic, historical, and laboratory data, physical examination findings, and follow-up information were extracted. A review of both the Hillsborough County Department of Health epidemiological report and the English-language literature was performed. Results: Fourteen female patients who attended a local high school developed audible inspiratory noise. Twelve of the 14 were seen at the University of South Florida Ear, Nose and Throat Center. The remaining 2 patients were evaluated by outside otolaryngologists but were included in all reports from the Department of Health. Environmental studies did not find noxious chemical or biological agents in the students' environments to explain the development of the symptoms. Physical and videostroboscopic examination identified two distinct laryngeal findings causing the audible stridor. One involved paradoxical vocal fold movement, and the other, supraglottic mucosal collapse into the airway. All patients underwent rigorous speech pathology intervention and structured treatment with either complete resolution or significant improvement, seen both clinically and on videostroboscopic evaluation. Conclusions: Audible stridor can arise from numerous disease processes. In the vast majority of presentations it occurs sporadically and on an individual basis. Our cohort is especially unusual because of the sheer number of patients. Our presentation of a case of mass psychogenic illness as the cause of vocal cord dysfunction with additional findings of laryngomalacia within a group of adolescent girls is the first in the English-language literature. The key to the diagnosis is recognition of the disorder and susceptible individuals by using a thorough physical examination with emphasis on the laryngoscopic and videostroboscopic findings. The systematic approach, undertaken by a team including an otolaryngologist, an allergist, a speech pathologist, and an epidemiologist, proved to be effective in the management of this complex disorder and highly unusual situation.

Abstract
This article presents disorders of periodic occurrence of laryngeal obstruction (POLO) resulting in noisy breathing and dyspnea and a variety of secondary symptoms. Included in this classification are glottic disorders, such as paradoxic vocal fold movement and vocal cord dysfunction. The supraglottic disorder, termed, intermittent arytenoid region prolapse or laryngomalacia, is also reviewed. Three categories of POLO are defined as irritant, exertional, and psychological.

Abstract
OBJECTIVE To perform a review of the epidemiology, pathogenesis, clinical presentation, diagnosis and management of laryngeal dyskinesia. METHODS A search of the Medline database from 1966 to 2003 was performed. A manual search was performed of the references of each article. RESULTS Laryngeal dyskinesia is a respiratory condition characterized by abnormal vocal cord adduction and airflow limitation at the level of the larynx in the absence of evidence of local organic disease. It typically presents to the ED as wheeze, stridor or apparent upper airway obstruction. It occurs across a wide age range, is more common in females, and is typically associated with a range of underlying psychopathologies. Diagnosis is often delayed and unnecessary emergency treatment such as intubation and tracheostomy is not uncommon. Patients are commonly on high-dose steroids and are frequent users of the health-care system, often over prolonged periods. There are multiple diagnostic features on history and examination, and flexible nasendoscopy of the vocal cords in the ED can be used to confirm the diagnosis. Treatment options in the ED include sedation and use of continuous positive airway pressure. Long-term treatment involves a multidisciplinary approach involving respiratory physicians/ear, nose and throat surgeons, speech therapy and psychiatry. CONCLUSION Laryngeal dyskinesia remains an under-appreciated cause of respiratory presentations to the ED. Emergency physicians are ideally placed to make the diagnosis and initiate appropriate referral for specific therapies that have a high level of success.

Abstract
Stridor as an initial symptom of a conversion reaction (hysteria) is rare. We report cases of hysterical stridor in two older women, unrelated and unacquainted, from the same rural community in Oman. Once the diagnosis was made, both patients were successfully treated with a single dose of an anxiolytic. We also review the literature on hysterical stridor and discuss the diagnostic dilemmas and therapeutic options.

Abstract
The diagnosis of a functional respiratory disorder is sometimes difficult and time-consuming, because the symptoms often resemble those of organic diseases. The most common entities are hyperventilation syndrome, psychogenic cough, sighing dyspnea, and vocal cord dysfunction. Typical signs are heavy breathing or dyspnea, cough or sneezing, various breathing sounds, tightness of the throat or chest, pain, and fear. Criteria for differentiation include the lack of nocturnal symptoms, the sudden occurrence, no typical trigger factors, the variable duration, a quick regression, and that symptoms do not respond to adequate pharmacotherapy and finally normal results of diagnostic work-up. Therapeutic options comprise psychological intervention (by reassurance, relaxation techniques, and behaviour therapy) and physiotherapy (e.g. breathing therapy, voice training). Intensive efforts should be made to diagnose functional symptoms at an early stage because this will prevent stigmatization and fixation of symptoms and disease, and also prevent children from undergoing unnecessary and potentially harmful therapies.

Abstract
Paroxysmal vocal cord movement/motion (PVCM), paroxysmal vocal cord dysfunction (PVCD), episodic paroxysmal laryngospasm (EPL), and irritable larynx syndrome (ILS) are terms used to describe laryngeal dysfunction masquerading as asthma, upper airway obstruction, or functional and organic voice disorders. The differential diagnosis of PVCM, PVCD, EPL, and ILS is critical to successful medical and behavioral management of the patient. During the past 10 years, 27 subjects, ages 15-79 years, were identified to have paroxysms of inspiratory stridor, acute respiratory distress, associated aphonia and dysphonia, resulting in misdiagnosis and unnecessary emergency treatments, including endotracheal intubation, cardiopulmonary resuscitation, massive pharmacotherapy, or tracheostomy. A multifactorial management program is proposed utilizing principles of motor learning, neurolinguistic programming model, respiratory and phonatory synchronization, relaxation techniques, concurrent monitoring of behavioral adjustments, and formal psychological counseling.

Abstract
BACKGROUND: Pulmonary disease such as asthma is a psychosomatic disorder vulnerable to exacerbations precipitated by psychological factors. A case is described in which a patient thought to have treatment-refractory asthma was discovered to have a conversion reaction, specifically paradoxical vocal cord dysfunction (PVCD), characterized by abnormal vocal cord adduction during inspiration. DATA SOURCES: Reports of PVCD were located using a MEDLINE search and review of bibliographies. MEDLINE (English language only) was searched from 1966 through December 1998 using the terms functional asthma, functional upper airway obstruction, laryngeal diseases, Munchausen's stridor, paradoxical vocal cord dysfunction, psychogenic stridor, respiratory stridor, vocal cord dysfunction, and vocal cord paralysis. A total of 170 cases of PVCD were reviewed. STUDY FINDINGS: PVCD appears to be significantly more common among females. PVCD spans all age groups, including pediatric, adolescent, and adult patients. PVCD was most often misdiagnosed as asthma or upper airway disease. Because patients present with atypical and/or refractory symptoms, several diagnostic tests are employed to evaluate patients with PVCD; laryngoscopy is the most common. Direct visualization of abnormal vocal cord movement is the most definitive means of establishing the diagnosis of PVCD. A number of psychiatric disturbances are related to PVCD, including conversion and anxiety disorders. PVCD is associated with severe psychosocial stress and difficulties with modulation of intense emotional states. CONCLUSIONS: Psychogenic respiratory distress produced by PVCD can be easily misdiagnosed as severe or refractory asthma or other pulmonary disease states. Recognition of PVCD is important to avoid unnecessary medications and invasive treatments. Primary care physicians can detect cases of PVCD by attending to clinical symptoms, implementing appropriate laboratory investigations, and examining the psychological covariates of the disorder. Psychotherapy and speech therapy are effective in treating most cases of PVCD.

Abstract
Vocal cord dysfunction (VCD) is a respiratory disorder often confused with asthma. Although previous case reports have implicated family and/or individual psychopathology in the etiology of this condition, this is the first paper to present prospective, case-control empirical data on a group of pediatric patients with VCD. A case-control methodology was employed to examine patients in terms of both family and individual functioning. Results indicate that patients with VCD were not different from asthmatic controls on measures of family functioning. However, they did experience significantly higher levels of anxiety and received a higher number of anxiety-related diagnoses such as separation anxiety and generalized anxiety disorder on a structured psychiatric interview. The nature of the relation between VCD and psychological symptoms in children is discussed. Etiologic and treatment issues are examined in the context of the findings.

Abstract
Vocal cord dysfunction (VCD), with its symptoms of stridor, air hunger, and chest or throat tightness, occurs primarily in active adolescents and young adults and may mimic exercise-induced asthma. Suspicions of VCD will be borne out by a mostly inspiratory stridor, abrupt onset and resolution of symptoms, an unpredictable symptom pattern, and the failure of usual asthma medications to resolve attacks. Laryngoscopy during acute symptoms is the definitive diagnostic tool. Panting can often stop an attack, and preventive treatment consists of patient education, speech therapy, and, when needed, psychological measures.

Abstract
We present a case of one patient with respiratory stridor that was resolved by speech therapy. Paradoxical vocal fold movements were observed by flexible fiberoptic videolaryngoscopy in this patient during episodes of wheezing and dyspnea. Otherwise, normal vocal fold movement was observed in normal conditions of breathing (out of the crisis) and during phonation. Many different terms have been used to describe this entity in the literature, and it is crucial that clinicians recognize the subtle signs of functional stridor. Paradoxical vocal fold motion has to be considered as an important cause of respiratory disease. Its recognition and treatment are discussed in this report.

Abstract
Three asthmatic patients with dyspnea and episodes of apparent bronchospasm unresponsive to conventional therapy are described. During these episodes variable extrathoracic upper airway obstruction and airflow limitation typical of bronchial asthma were demonstrated by spirometry test results. In one patient, paradoxical vocal cord motion was identified by fiberoptic laryngoscopy. We believe these patients represent an unusual subgroup of asthmatic subjects who manifest laryngeal dysfunction. Recognition of this upper airway component to airflow limitation in some asthmatic patients may help physicians avoid potentially unnecessary therapy with systemic steroids and endotracheal intubation.

Abstract
Episodic paroxysmal laryngospasm (EPL) is a sign of laryngeal dysfunction, often without a specific organic etiology, which can masquerade as asthma, vocal fold paralysis, or a functional voice disorder. The intermittent respiratory distress of EPL may precipitate an apparent upper airway obstructive emergency, resulting in unnecessary endotracheal intubation, cardiopulmonary resuscitation, or tracheostomy. During 27 months, seven women and three men, age 30-76 years, were assessed by a high diagnostic index of suspicion, an intensive history including psychosocial factors, physical examination of the airways, provocative asthma testing, and swallowing studies. Videolaryngoscopy, stroboscopy, and pulmonary flow-volume loop testing were definitive. The classic appearance was paradoxic inspiratory adduction of the anterior vocal folds with a posterior diamond-shaped glottic gap. During an attack of stridor or wheezing, attenuation of the inspiratory flow rate as depicted by the flow-volume loop suggested partial extrathoracic upper airway obstruction. Swallowing evaluation by videolaryngoscopy and videosophagography may uncover gastroesophageal reflux disease. Hallmarks of management include patient and family education by observation of laryngoscopic videos, a specific speech therapy program, psychotherapy, and medical treatment of associated disorders. Electromyography may become a valuable future adjunct. Unlike laryngeal dystonia, patients with EPL do not benefit from botulinum toxin type A.

Abstract
This article presents the case history of a 4 month old infant diagnosed with Paradoxical Vocal Cord Dysfunction (PVCD) secondary to gastroesophageal reflux. The child presented with intermittent stridor which responded promptly to treatment of her reflux. This is believed to be the youngest person with PVCD reported in the literature and supports the concept that PVCD may be associated with multiple etiologies.

Abstract
In the past 20 years, several cases have been reported describing an upper airway obstruction reportedly caused by psychological factors. This paper reviews 48 reported cases of "psychogenic stridor." Patients with psychogenic stridor usually present to primary care physicians with symptoms of asthma or stridor unresponsive to conventional treatments. Of the 48 cases reviewed, 52% received a diagnosis of conversion disorder. The obstruction was severe enough to cause intubation and tracheostomies in some patients. In addition, many suffered from the unnecessary side effects of corticosteroids. The literature is reviewed and medical and psychiatric differential diagnosis and treatment are discussed.

Abstract
A 75 year old woman presented with a three week history of severe dyspnoea and cough. Auscultation and spirometry suggested extrathoracic inspiratory airway obstruction, and bronchoscopy showed abnormal motion of the arytenoid region (supraglottic area), causing upper airway obstruction only during forced inspiratory efforts. Sedatives improved the symptoms within a week. It is suggested that reversible malfunction of the arytenoid region can be responsible for upper airway obstruction.

Abstract
A 15-year-old boy, known to have asthma, developed acute inspiratory airway obstruction with marked stridor. Spirometry indicated extrathoracic airway obstruction and a bronchofiberoptic examination disclosed narrowing in the hypopharynx. After administration of sedatives, the stridor suddenly disappeared. Psychotherapy decreased the frequency of subsequent stridor attacks. It is suggested that psychogenic pharyngeal constriction may have caused the upper airway obstruction with respiratory distress.

Abstract
We report the case of a young man who presented to 3 emergency departments with apparent upper airway obstruction and was intubated each time before being diagnosed with paradoxical vocal cord motion. His previous discharge diagnoses were laryngeal edema secondary to anaphylaxis, even though he had no other objective findings of IgE-mediated disease. Flexible fiberoptic laryngoscopy demonstrated tight apposition of the vocal cords during inspiration while symptomatic, but normal movement when asymptomatic. Psychiatric evaluation revealed severe posttraumatic stress disorder. Of the approximately 41 reported cases of functional airway obstruction in the medical literature, only two have been adult males and none have been associated with posttraumatic stress disorder. The current literature is reviewed, and an approach to evaluation and management of such patients is provided.

Recent research has increased the still limited understanding about the generation of continuous adventitious lung sounds. These sounds all have a definite pitch, such as in stridor and wheezing. With the use of waveform analysis, one can examine more closely the relationship between what is heard and the pathophysiology causing the sound. Clinical examples are given to show the utility and limitations of current lung sounds analysis techniques.

Abstract
We present the cases of three patients with stridor that resolved spontaneously. Paradoxical vocal cord motion was documented in one patient. Normal vocal cord motion was present in the other two patients, but stridor had resolved in both cases. Many different terms have been used to describe this entity in the literature. Emergency physicians must recognize the subtle signs of hysterical stridor. Once more serious etiologies are ruled out, sedation and reassurance instead of aggressive airway intervention are required for this benign condition.

Abstract
A case of functional upper airway obstruction is presented. The case is unusual because even though no identifiable organic cause could be found for dyspnea and stridor, the patient developed respiratory failure from respiratory muscle fatigue.

Abstract
Obstruction of the laryngeal airway is a life threatening problem due normally to obstructive pathology within the upper aero-digestive tract. We describe four cases of laryngeal stridor (two adults and two children) of psychogenic origin, one of which required a tracheostomy. The literature is reviewed and the subsequent pattern of this disease documented on the basis of 28 patients previously described.

Abstract
A case of acute respiratory obstruction in the immediate postoperative period is described in a young woman who emerged from general anaesthesia after a Caesarean section for fetal distress. She had a pregnancy complicated by disabling polyhydramnios and anxiously anticipated the birth of a child with a diaphragmatic hernia, diagnosed antenatally. The cause of the airway obstruction was functional in nature as confirmed by flexible fibreoptic laryngoscopy. The diagnosis, paradoxical vocal cord motion, has to be considered as an infrequent cause of postoperative airway obstruction; its recognition and treatment are discussed. The patient did not have a history which might have indicated its possible occurrence. It is suggested that paradoxical vocal cord movement in a more mild form may be overlooked as cause for postoperative stridor and airway obstruction.

Abstract
A 4.75-year-old male presented with several episodes of expiratory stridor leading, on one occasion, to a respiratory arrest and intubation. A detailed evaluation emphasizing physiological and anatomical studies revealed no organic basis for the patient's upper airway obstruction. Emphasis is placed on one method found to be helpful in the differentiation of an organic versus a psychogenic type of respiratory disorder. Recognition of functional airway obstruction in children may prevent inappropriate therapy and allow proper psychiatric intervention.

Abstract
We have obtained physiologic and psychiatric evaluations on five subjects with episodic laryngeal dyskinesia (LD) and compared them with three patients with expiratory laryngeal stridor and asthma (ELS), and five with chronic asthma (CA). Laryngoscopy confirmed adduction of the vocal cords. Diminished inspiratory flow rates with an expiratory/inspiratory ratio of 1.5 to 3.3 was demonstrated by flow volume studies. Flows improved strikingly while breathing an 80 percent helium/20 percent oxygen mixture. Patients with LD showed varying degrees of depression and sought some form of secondary gain. A histrionic personality, conversion or factitious disorders are not an essential part of this syndrome. Tracheostomy may seldom be necessary in the managing of the acute crisis of LD. Reassurance, oxygen, intermittent positive pressure, and sedation may be sufficient. Mildly depressed patients decreased the frequency and severity of wheezing episodes after receiving reassurance and a clear explanation of ventilatory mechanics.
