Asthma III: Clinical Manifestations

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Asthma-II: Pathophysiology and Classification

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma-III: Symptoms and Complications

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Asthma-IV: Diagnostic and Management

Asthma-IV: Diagnostic and Management

The diagnosis and management of asthma are comprehensive, encompassing clinical assessments, lung function tests, and pharmacological interventions. Here's an overview:
Clinical Assessment for Asthma:

Asthma: Pathogenesis and Management

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Asthma I: Introduction

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Summary

Paradoxical vocal fold motion dysfunction (PVFMD) is more common in asthma patients. This condition, characterized by vocal cord adduction, can mimic asthma symptoms, leading to misdiagnosis.

Area of Science:

Laryngology
Pulmonology
Respiratory Medicine

Background:

Paradoxical vocal fold motion dysfunction (PVFMD) involves vocal cord adduction during respiration, causing airway obstruction.
PVFMD symptoms mimic asthma, often leading to misdiagnosis as refractory asthma and unnecessary treatments.

Purpose of the Study:

To determine the prevalence of PVFMD in asthma patients.
To describe the relationship between asthma and PVFMD.

Main Methods:

A descriptive study involving laryngoscopy and pulmonary function tests.
94 asthma patients and 40 control subjects were examined.

Main Results:

PVFMD prevalence was 19% in asthma patients versus 5% in controls (P < 0.001).
No correlation found between PVFMD and asthma severity or attacks.
Laryngopharyngeal reflux and allergies were more common in PVFMD+ patients.

Conclusions:

Asthma prevalence significantly increases the likelihood of developing PVFMD.
PVFMD should be considered in asthma patients presenting with specific respiratory symptoms.
