Chronic Obstructive Pulmonary Disease01:24

Chronic Obstructive Pulmonary Disease

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
Chronic Pharyngitis01:23

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
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.

Chronic Obstructive Pulmonary Disease-I: Introduction01:20

Chronic Obstructive Pulmonary Disease-I: Introduction

Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.
Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features01:24

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Summary
This summary is machine-generated.

Dysphagia and dysphonia are common in severe chronic obstructive pulmonary disease (COPD) but often go unnoticed. Objective screening for swallowing disorders is recommended, even without vocal complaints.

Area of Science:

  • Pulmonology
  • Otolaryngology
  • Gastroenterology

Background:

  • Chronic obstructive pulmonary disease (COPD) exacerbations are linked to severity.
  • Laryngeal aspiration is a risk factor for COPD exacerbations.
  • Dyspnea in COPD can impair both phonation and swallowing.

Purpose of the Study:

  • To assess the associations between COPD, dysphonia, and dysphagia.
  • To determine the prevalence of phonation and swallowing disorders in severe COPD.
  • To investigate if vocal disorders indicate dysphagia in at-risk patients.

Main Methods:

  • Prospective study of 29 patients with severe COPD (Group E).
  • Exclusion criteria: neurodegenerative disease, head and neck cancer history.
  • Concomitant assessment of phonation and swallowing functions.

Main Results:

  • High prevalence of objective dysphonia and dysphagia, underestimated by self-reports.
  • Over 50% of patients had swallowing mechanism deficits, including delayed pharyngeal reflex.
  • The s/z ratio was the only significant predictor of dysphagia.

Conclusions:

  • Dysphagia and dysphonia are frequent and underestimated in severe COPD.
  • Systematic objective screening for swallowing disorders is advised.
  • Screening is recommended even in the absence of patient complaints or dysphonia.
