Assessing laryngeal function and hypersensitivity.

Pulm Pharmacol Ther 2019 Apr 17. Epub 2019 Apr 17.

Department of Respiratory Medicine, Royal Brompton Hospital, London, SW3 6HP, UK. Electronic address:

The larynx is one of the most highly innervated organs in humans, adapted to simultaneously deliver several key respiratory functions including airway protection, swallowing and phonation. In some individuals the larynx can adopt a state that could be considered 'dysfunctional' or maladaptive; resulting in or contributing to a range of clinical disorders such as chronic refractory cough, inducible laryngeal obstruction (previously termed paradoxical vocal fold movement or vocal cord dysfunction), muscle tension dysphonia and globus pharyngeus. These disorders appear to display significant overlap in clinical symptomology and in many cases have features of concomitant or allied sensory dysfunction; often described as laryngeal hypersensitivity.

Vocal Cord Dysfunction: Analysis of 27 Cases and Updated Review of Pathophysiology & Management.

Int Arch Otorhinolaryngol 2019 Apr 24;23(2):125-130. Epub 2018 Oct 24.

Department of ENT, Little Flower Hospital, Ernakulam, Kerala, India.

 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.  This descriptive study was intended to analyze presentations of vocal cord dysfunction in a tertiary care referral hospital.

Exercise-Induced Dyspnea in Children and Adolescents: Differential Diagnosis.

Pediatr Ann 2019 Mar;48(3):e121-e127

Exercise-induced dyspnea in children and adolescents can occur for many reasons. Although asthma is the common cause, failure to prevent exercise-induced asthma by pretreatment with a bronchodilator, such as albuterol, indicates that other etiologies should be considered. Other causes of exercise-induced dyspnea include exercise-induced vocal cord dysfunction, exercise-induced laryngomalacia, exercise-induced hyperventilation, chest wall restrictive abnormalities, cardiac causes, and normal physiologic limitation.

Spirometry and provocation tests for vocal fold dysfunction diagnosis: a retrospective case series.

Swiss Med Wkly 2018 12 4;148:w14692. Epub 2019 Jan 4.

Division of Immunology and Allergy, Department of Medical Specialties, University Hospitals and Medical Faculty, Geneva, Switzerland / Jules Gonin Eye Hospital, Lausanne, Switzerland.

Aims: Vocal cord dysfunction (VCD) is characterised by paradoxical inspiratory laryngeal motion and is often misdiagnosed as asthma. Definitive diagnosis of VCD is difficult, because laryngoscopy is positive only during symptomatic episodes or upon provocation with exercise or inhaled irritants. The aims of the study were to better characterise the symptomatology of patients with VCD and to evaluate the potential usefulness of less-invasive diagnostic tools, namely provocation tests and spirometry.

Tracheobronchomalacia and Excessive Dynamic Airway Collapse: Medical and Surgical Treatment.

Semin Respir Crit Care Med 2018 Dec 14;39(6):667-673. Epub 2019 Jan 14.

Division of Thoracic Surgery and Interventional Pulmonology, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts.

Excessive central airway collapse (ECAC) is characterized by excessive narrowing of the airway lumen during exhalation leading to dyspnea, cough, mucostasis, recurrent respiratory infections, and poor quality of life. Tracheobronchomalacia and excessive dynamic airway collapse are heterogeneous entities of ECAC and are characterized by a diverse nonspecific symptom profile. Although the pathophysiology of airway mechanics as well as morphology in both entities is different, current evidence so far shows no practical benefit in making such distinction since both have similar symptoms and the diagnostic and therapeutic work-ups are the same.

Dynamic tonsillar prolapse masquerading as paradoxical vocal fold movement dysfunction.

Int J Pediatr Otorhinolaryngol 2019 Mar 2;118:68-72. Epub 2018 Dec 2.

Division of Pediatric Otolaryngology, UPMC Children's Hospital of Pittsburgh, USA.

Introduction: Paradoxical vocal fold movement dysfunction (PVFMD) is a disorder in which the vocal folds involuntarily adduct during inspiration resulting in stridor, cough, dysphonia and dyspnea. Diagnosis of PVFMD is difficult given the episodic nature of the disorder and the often-normal laryngeal exam in between episodes. Moreover, additional sources of obstruction have been identified as sources of Periodic Occurrence of Laryngeal Obstruction (POLO). Read More

Asthma: Differential Diagnosis and Comorbidities.

Front Pediatr 2018 3;6:276. Epub 2018 Oct 3.

Paediatric Pulmonology & Respiratory Intermediate Care Unit, Sleep and Long Term Ventilation Unit, Department of Paediatrics, Paediatric Hospital "Bambino Gesù" Research Institute, Rome, Italy.

Childhood asthma remains a multifactorial disease with heterogeneous clinical phenotype and complex genetic inheritance. The primary aim of asthma management is to achieve control of symptoms, in order to reduce the risk of future exacerbations and progressive loss of lung function, which results especially challenging in patients with difficult asthma. When asthma does not respond to maintenance treatment, firstly, the correct diagnosis needs to be confirmed and other diagnosis, such as cystic fibrosis, primary ciliary dyskinesia, immunodeficiency conditions or airway and vascular malformations need to be excluded.

Hemi-laryngopharyngeal spasm as a novel cause of inducible laryngeal obstruction with a surgical cure: report of 3 cases.

J Neurosurg 2018 Jul 1:1-5. Epub 2018 Jul 1.

4Anesthesiology, Pharmacology and Therapeutics at the University of British Columbia, Vancouver, British Columbia, Canada.

Inducible laryngeal obstruction has been described under at least 40 different monikers, including vocal cord dysfunction, paroxysmal vocal fold motion, and irritable larynx. The etiology of this condition is believed to be laryngeal hyperactivity in response to psychological issues or acid reflux. Most patients are treated with some combination of proton pump inhibitors, speech therapy, and psychotherapy. Read More

Gasping for a Diagnosis: Pediatric Vocal Cord Dysfunction.

Authors:
Mariel Wenzel

J Pediatr Health Care 2019 Jan 13;33(1):5-13. Epub 2018 Apr 13.

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.

Observational study of laryngoscopy plus flow-volume loops during exercise.

Clin Case Rep 2018 04 4;6(4):735-740. Epub 2018 Mar 4.

Department of Otorhinolaryngology Mayo Clinic 200 First St. SW Rochester Minnesota 55905.

Laryngoscopy is the gold standard to diagnose exercise-induced laryngeal obstruction, though inspiratory flow-volume loop may provide a clue. We combined tidal flow-volume loop analysis laryngoscopy during exercise and found that cigar-shaped - flattened - inspiratory loops are associated with obstruction. Pursed-lip breathing slows inhalation thereby reducing vocal fold adduction. Read More
