Asthma III: Clinical Manifestations01:13

Asthma III: Clinical Manifestations

49
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 I: Introduction01:28

Asthma I: Introduction

112
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...

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma-II: Pathophysiology and Classification

4.7K
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: Pathogenesis and Management

1.5K
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.

Summary

A young woman experienced respiratory failure due to a large central tracheal tumor, initially misdiagnosed as asthma. Surgical removal was successful, revealing adenoid cystic carcinoma.

Area of Science:

  • Respiratory Medicine
  • Oncology
  • Pulmonology

Background:

  • A young woman presented with respiratory failure and a history of asthma.
  • Recurrent wheezing was the primary symptom for two years.
  • Initial diagnosis focused on managing presumed bronchial asthma.

Observation:

  • Difficult endotracheal intubation was noted upon admission.
  • Flexible bronchoscopy revealed a significant central tracheal tumor.
  • The tumor obstructed over 90% of the tracheal lumen.

Findings:

  • Rigid bronchoscopy with ventilation enabled tumor debulking.
  • Histopathology confirmed the tumor as adenoid cystic carcinoma.
  • This rare tracheal malignancy presented as respiratory failure.
