Bronchiectasis
CF
Restrictive Diseases
Sarcoidosis
IPF
Penumoconiosis
Asthma Samters Triad
Asthma
Nasal Polyps
NSAID allergy
Asthma Sx
dyspnea, wheezing, cough (worse at night)
Asthma PE
Prolonged expiration with wheezing
Hyperresonance to percussion
Decreased breath sounds
Status Asmaticus
Inability to speak in full sentences, AMS, pulsus paradoxis
Asthma Dx
Gold Standard: PFT
Methacholine challenge test
Bronchodilator challenge
PFT in asthma
decreased FEV1, decreased FEV1/FVC
Methacholine challenge in asthma
> /= 20% decrease in FEV1
Tx acute asthma
- SABA: albuterol (bronchodilators, nebs q20 min x3)
- Anticholinergics: Ipratropium
- Corticosteroids: Prednisone, prednisolone, methylprednisone (3-5d)
Tx chronic asthma
Start with SABA PRN then add an ICS (beclamthasone, Flunisolide) then add LABA (Salmeterol/fometerol)
Leuko Modifiers if allergies are causing asthma
IV mag if uncontrolled severe
Acute Bronchitis etiology
MC cause: ADENOVIRUS, parainfluenza
Inflam of trachea/bronchi often post URI
Hallmark is cough 1-3 weeks
Bronchitis dx/ tx
Clinical usually, CXR is nonspecific
Tx: TOC is sx tx
- fluids
- rest
- antitussives
Bronchiectasis etiology
Recurrent/chronic lung infections: H. Flu (MC)
CF usually Pseudomonas
Bronchiectasis sx
Daily chronic cough with thick, mucopurulent, foul-smelling sputum
Hemoptysis
Bronchiectasis Dx
CT scan TOC: Dilated airway, bronchial wall thickening
TRAM TRACKS
PFT: obstructive pattern (decreased)
Signet Ring Sign
pulmonary artery coupled with dilated bronchus
Bronchiectasis Tx
Abx TOC
- empiric ampicilin, amox, bactrim
- pseudomonal fluoroquin, pip/tazo
Bronchodilators for mucus management
Bronchial Carcinoid tumors etiology
Enterochromaffin cells
MC in GI tract, lung is 2nd MC
Can secrete serotonin/ACTH/ADH/melanocyte stim hormone
Bronch Tumor sx
focal wheeze, cough, recurrent PNA, hemoptysis
SIADH, Cushing’s syndrome
Carcinoid syndrome
diarrhea d/t increased serotonin, increased bradykinin and histamine –> flushing, tachycardia, bronchoconstriction
Bronch Carcinoid tumor Dx/ Tx
Bronchoscopy
Tx: Surgical excision is definitive
Octreotide to reduce sx
COPD etiology
progressive, irreversible airflow obstruction d/t loss of elastic recoil and increased resistance
Emphysema + Bronchitis
COPD rsk fx
Sm MC
Alpha 1 antitrypsin deficiency: genetic <40yo
