Trachea01:22

Trachea

6.2K
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

Asthma III: Clinical Manifestations

37
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: Introduction

84
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-I: Introduction

3.6K
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: 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.

Area of Science:

  • Thoracic Surgery
  • Oncology
  • Pulmonology

Background:

  • Primary tracheal tumors are rare, with most adult cases being malignant.
  • Schwannomas, a type of nerve sheath tumor, are exceptionally uncommon in the tracheobronchial tree.

Observation:

  • A 37-year-old male presented with progressive dyspnea, initially misdiagnosed as asthma.
  • Imaging and bronchoscopy revealed a tracheal mass obstructing the left stem bronchus.

Findings:

  • Endoscopic laser resection was insufficient, necessitating surgical excision of the schwannoma.
  • Histopathology confirmed a benign schwannoma, with no recurrence after surgical resection and primary anastomosis.

Implications:

  • Intratracheal masses should be considered in the differential diagnosis of refractory asthma or unexplained dyspnea.
  • Surgical resection is a viable treatment for benign tracheal schwannomas, ensuring long-term disease-free survival.
