Bronchiectasis definition
|
permanent dilation of bronchi, w/ peri-bronchial inflam & organization w/ muco-purulent debris
|
|
|
Bronchiectasis path
|
- Impaired mucus flow -> microbial colonization -> microbial products (elastase)
– all of this causes mucus hypersecretion and structural damage |
|
|
Bronchiectasis Sx
|
cough, purulent sputum, hemoptysis, localized rales or rhonchi, and clubbing
|
|
|
Bronchiectasis causes of impaired flow how?
|
1) Obstruction to outflow
2) Abnormal mucus (CF) 3) abnormal ciliary function (1oCD) |
|
|
Bronchiectasis treatment
|
drainage, antibiotics, and bronchodilators – surgical resection is rarely needed
|
|
|
Bronchiectasis radiology
|
airway dilation which extends to the periphery
|
|
|
Upper>lower lobe emphysema
|
suggests centrilobular type, from smoking
|
|
|
Lower>upper lobe emphysema
|
suggests panlobular type, from A1AT deficiency
|
|
|
BOOP definition
|
Bronchiolar lumen and alveolar airspace fibroblastic proliferation
|
|
|
BOOP clinical
|
- acute onset cough, dyspnea, fever, and malaise
- multiple associations (collagen-vascular disease) - most patients respond to corticosteroids |
|
|
BOOP radiology
|
will show multiple patchy airspace infiltrates
|
|
|
BOOP path
|
will show patchy fibromyxoid plugs in distal bronchioles and alveoli, +/- endogenous lipid pneumonia
|
