Case Report
A 35-year-old woman was admitted for respiratory distress after 1week of increasing dyspnea, despite treatment with inhaledcorticosteroids and bronchodilators. The patient had been treated forsuspected asthma since childhood. During the last 6 years, the patienthad experienced six similar episodes. Tracheal intubation was performedon four occasions, and tracheostomy was performed twice. During thelast episode, the respiratory obstruction resolved completelyimmediately after intubation. PVCM was
Discussion
The clinical presentation of PVCM ranges from mild dyspnea toacute respiratory distress. The condition should be considered in theacute care setting since it is frequently confused or associated withasthma.1 The case reported here provides an example ofsevere PVCM with acute hypercapnic respiratory failure.
PVCM typically disappears during sleep. In our patient, airflowlimitation resolved during acute attacks culminating in syncope orafter IV sedation. This phenomenon provides a rationale for

2018, Journal of VoiceCitation Excerpt :In contrast, treatment protocol for VFD suggests a multidimensional approach, which considers different etiologies and treatment including speech and language therapy. The speech therapy that includes laryngeal relaxation and breathing exercises is recommended as the main treatment particularly for chronic VFD.15–18 With the aim of validating a questionnaire for monitoring treatment response, the researchers aimed to adapt and evaluate validity and reliability of the Persian version of VFDQ questionnaire.

2014, Otolaryngologic Clinics of North AmericaCitation Excerpt :Continuous positive airway pressure has been shown to relieve expiratory constriction in case reports,31 and an investigational mask that functions as a one-way “inspiratory valve” was developed to decrease the rate of inspiratory airflow, reducing stridor and perhaps breaking the spiral of anxiety and distress that patients feel when they hear their own noisy breathing.59 For acute or severe cases, benzodiazepines, heliox, and even laryngeal botox have been used with some benefit.51,60,61 Managing reflux, allergies, sinus disease, and extreme dryness is crucial and often leads to the prescription of medications during the evaluation of PVFMD.
