Abstract:
A case of vocal cord dysfunction (VCD) is presented, followed by a discussion of the clinical characteristics, pathogenesis, diagnosis, and management of this disorder. Special emphasis is given to clinical pearls and pitfalls for the practicing allergist. VCD is a common condition that mimics asthma. Dyspnea, cough, and chest tightness are frequent manifestations of the disease. A high degree of clinical suspicion is required to recognize VCD and diagnosis is made most confidently by laryngoscopy. The mainstay of treatment for VCD is reassurance, speech therapy, and treatment of associated comorbidities including gastroesophageal reflux disease, postnasal drip syndrome, and psychiatric conditions.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Respiratory System Abnormal Finding I: Inspection and Percussion
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...
Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
