47
Q

A

.

48
Q

Bronchiectasis. development requires infectious insult in combination with impaired bacterial clearance

A

.

49
Q

Bronchiectasis. exacerbations why and what symptoms?

A

Patients may have frequent exacerbations (due to bacterial infections) characterized by:
a. Fever
b. Increased dyspnea
c. Increased sputum production

50
Q

Bronchiectasis. Best diagnostic?

A

CT
i. Bronchial dilation
ii. Lack of airway tapering
iii. Bronchial wall thickening

xray is not diagnostic, but may show linear atelectasis, dilated and thickened airways

51
Q

bronchiectasis differential?

A

a. Chronic Bronchitis:
i. Sputum production is less prominent than bronchiectasis
ii. Exacerbations are usually viral in chronic bronchitis
iii. It is associated with smoking, while bronchiectasis is not

52
Q

bronchiectasis due to CF.

A

In young patients, because CF is usually in young people.

53
Q

bronchiectasis due to CF. pathophysiology?

A

a. Defective sodium and chloride transport leads to thick secretions and impaired mucociliary clearance

b. Chronic bacterial infection ensues, leading to enhanced neutrophil recruitment and excessive release of Elastase (which contributes to bronchial airway damage)

54
Q

bronchiectasis due to CF. causative mo?

A

pseudomonas aeruginosa

55
Q

bronchiectasis due to CF. what lung part involvement?

A

Upper lung lobe involvement is characteristic of bronchiectasis due to CF, and helps differentiate it from bronchiectasis due to other causes
