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...
Respiratory System Abnormal Finding II: Palpation and Auscultation01:31

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:
Respiratory System Abnormal Finding I: Inspection and Percussion01:30

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...
Esophageal Perforation-I: Introduction01:22

Esophageal Perforation-I: Introduction

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.
Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
Clinical Manifestations:
Common Respiratory Disorders01:31

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,...

Summary
This summary is machine-generated.

Vocal cord dysfunction (VCD) causes breathing issues and is often misdiagnosed as asthma. This case highlights how thorough investigation is key to correctly identifying VCD, even when asthma is suspected.

Area of Science:

  • Otolaryngology
  • Pulmonology
  • Allergology

Background:

  • Vocal cord dysfunction (VCD) involves paradoxical vocal cord adduction, causing symptoms like shortness of breath, wheezing, and stridor.
  • VCD is frequently misdiagnosed as asthma due to overlapping clinical presentations.
  • Diagnosing VCD can be challenging due to its variable nature and requires direct visualization of the upper airway.

Purpose of the Study:

  • To report a case of a patient initially diagnosed with asthma who was found to have VCD.
  • To emphasize the importance of comprehensive evaluation in differentiating VCD from asthma.

Main Methods:

  • Clinical case presentation of a 41-year-old female.
  • Referral to an Allergology clinic with a presumed asthma diagnosis.
  • Diagnostic workup including rhinolaryngoscopy for direct observation of the upper airway.

Main Results:

  • The patient presented with symptoms mimicking asthma.
  • Thorough investigation, including direct airway visualization, led to the diagnosis of VCD.
  • VCD was identified as the underlying cause of the patient's respiratory symptoms.

Conclusions:

  • Vocal cord dysfunction can present similarly to asthma, leading to misdiagnosis.
  • Rhinolaryngoscopy is crucial for the definitive diagnosis of VCD.
  • A high index of suspicion and comprehensive diagnostic approach are necessary for accurate VCD diagnosis.
