Bronchial dilation


Bronchial dilation, the cardinal sign of bronchiectasis

FACED scale uses ---------------- to predict clinical outcomes in bronchiectasis as one of the parameters.

Correct! Wrong!

FACED scale uses the FEV-1 (forced expiratory volume in 1 second), age of the affected person, presence of chronic infection, extent of disease (number of lung lobes involved) and dyspnea scale rating (MRC dyspnea scale) to predict clinical outcomes in bronchiectasis.

Which of the following has a particular propensity for colonizing damaged airways in bronchiectasis?

Correct! Wrong!

Pseudomonas

Which of the following cells dominate in airway inflammation of bronchiectasis?

Correct! Wrong!

Neutrophils


Neutrophils dominate airway inflammation in bronchiectasis, driven by high concentrations of neutrophil chemoattractants such as interleukin-8 (CXCL-8), and leukotriene B4.
