Abstract

Vocal cord dysfunction can coexist with or masquerade as asthma. Vocal cord dysfunction, when coexistent with asthma, contributes substantially to the refractory nature of the respiratory problem. To report a case of an asthmatic patient with vocal cord dysfunction and a previously unreported unique expiratory flow volume curve. A 16-year-old female, known to have asthma, developed increased frequency of her asthma exacerbations. Spirometry, during symptoms, showed an extrathoracic airway obstruction with a reproducible unique abrupt drop and rise in the expiratory flow volume loop. Laryngoscopy showed adduction of the vocal cords during inspiration and expiration. We report a unique expiratory flow volume curve in an asthmatic with vocal cord dysfunction that resolved with panting maneuvers. Speech and psychological counseling helped prevent future attacks.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
