Abstract:
Thoracic vertebral osteophytes have been reported to affect the adjacent organs. We report an uncommon case of localized bronchiectasis secondary to an allergic reaction stimulated by vertebral osteophytes. A man in his 60s presented with a 2.5-cm lung nodule connected to the proximal segmental bronchus in the right lower lobe near vertebral osteophytes that caused obstructive pneumonia due to mucoid impaction. His medical history suggested a tendency for development of allergic respiratory tract reactions. Thoracoscopic resection was successfully performed, and histopathologic examination confirmed the pathogenesis.

Asthma: Pathogenesis and Management
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.
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
