Larynx

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...

Respiratory System Abnormal Finding II: Palpation and Auscultation

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.

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.
Primary Symptoms of COPD:

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like 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

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
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

Tracheostomy Decannulation

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
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...

Summary

Vocal cord dysfunction (VCD) is often misdiagnosed as asthma due to similar symptoms. This review clarifies VCD

Area of Science:

Pulmonology
Otolaryngology

Background:

Vocal cord dysfunction (VCD) presents as paradoxical vocal cord closure during inhalation.
It frequently mimics asthma and other upper airway obstruction conditions.
Misdiagnosis of VCD leads to unnecessary treatments and patient morbidity.

Purpose of the Study:

To explore the clinical features, causes, diagnosis, and management of VCD.
To differentiate VCD from asthma in clinical practice.

Main Methods:

Review of clinical features.
Analysis of proposed etiologies.
Discussion of diagnostic considerations.
Outline of management strategies.
Comparison with asthma symptoms and diagnostic criteria.

Minimally Invasive Murine Laryngoscopy for Close-Up Imaging of Laryngeal Motion During Breathing and Swallowing

Published on: December 1, 2023

Main Results:

VCD is characterized by inspiratory stridor and throat tightness.
Diagnostic challenges include its mimicry of asthma.
Effective management involves laryngeal sensory retraining and speech therapy.

Conclusions:

Accurate differentiation of VCD from asthma is crucial for appropriate patient care.
Early diagnosis and targeted management of VCD can prevent morbidity associated with misdiagnosis.
