Pulmonology Flashcards
Asthmatic triad
Nasal Polyps
Sensitivity to ASA
Wheezing
Allergic Bronchopulmonary Aspergillosis
Ongoing immunologic response to Aspergillus causing persistent eosinophilic airway inflammation, increased IgE, and tissue damage w/ airway remodeling
Sx: Brown, mucous plugs in sputum, productive cough, wheeze
Dx: Elevated IgE, asthma, positive Aspergillius skin antigen test, bronchiectasis/infiltrates on CXR
Vocal Cord Dysfunction
Due to paradoxical adduction of the vocal cords during inspiration
May present like asthma w/ similar triggers but patients complain of throat tightness and voice dysfunction during attacks as well; they will not respond to oral inhalers
Tx: Speech therapy
Bronchial Thermoplasty
Radiofrequency airway treatment used for severe asthma that is not controlled despite high dose inhaled glucocorticoid/LABA therapy
Patients must also have FEV > 60%
=»Decreased exacerbations and improved quality of life
Antidote for Cyanide poisoning
IV hydroxycobalamin
CTEPH diagnostic criteria and treatment
- Mean pulmonary artery pressure >25mmHg
- Evidence of vascular webs, intimal irregularities, and luminal narrowing on CT-PA
- **V/Q scan is more sensitive in this case
Tx: Pulmonary thromboendartectomy
Lung Volume Reduction Surgery candidate
Patients w/ upper lobe-predominant COPD and significant exercise limitation even after pulm rehab
***Not candidate w/ FEV1 <20%, DLCO <20%, or non-upper lobe predominant disease
Otherwise, can lead to increased exercise tolerance, quality of life, and survival
Chronic Simple Silicosis CT findings
Upper-zone predominant disease w/ centrilobular or perilymphatic nodules 1-9mm in diameter
Indicator for need of thoracostomy drainage for parapneumonic effusion
pH < 7.2
Cryptogenic Organizing Pneumonia
Present w/ cough, fever, and malaise for 6-8 weeks; initial CXR mimics pneumonia
CT: Patchy ground glass opacity, alveolar consolidation w/ peripheral and basal predominance
Assoc. w/ CT disease, infxn, drugs
Resolves w/ steroids
Idiopathic Pulmonary Fibrosis
Presents w/ >6month dry cough, dyspnea on exertion, often times clubbing as well
CXR: Bibasilar septal line thickening w/ reticular changes, volume loss, bronchiectasis
CT: Basal and peripheral predominant septal line thickening w/ traction bronchiectasis and honeycomb changes
Tx: Pirfenidone or nintedanib
- **DO NOT INTUBATE =» Extremely poor prognosis
- Typically, only 3-5yr life expectancy at diagnosis anyways
Respiratory bronchiolitis
Associated w/ smoking; presents w/ combined restriction and obstruction on PFTs
CT: Centrilobular nodules and ground-glass opacity in upper lobe distribution
Tx: Stop smoking; ? steroid beneft
Desquamative interstitial pneumonia
Found in smokers; CT shows basal-predominant and peripheral predominant ground glass opacities w/ occasional cysts; basically like respiratory bronchiolitis but peripheral
Pulmonary Langerhans Cell Histiocytosis
Smoking DPLD
CT: Diffuse, thin walled cysts and pulmonary nodules that are mid and upper lobe predominant, biopsy shows langerhan’s cells positive for CD1a or S100
Can be associated w/ PAH
Hypersensitivity Pneumonitis
Acutely presents w/ flu-like illness; manage by removing offending agent
CT: Acute-ground glass opacification w/ centrilobular micronodules that are upper and mid lobe predominant
Chronic- Mid and upper lung predominant septal lung thickening w/ traction bronchiectasis
Lofgren Syndrome
- Bilateral hilar lymphadenopathy
- Migratory polyarthralgia
- Erythema nodosum
- Fever
Radiograph Staging of Sarcoid
I-Hilar lymphadenopathy w/ normal lung parenchyma
-90% resolution w/ no treatment
II-HIlar lymphadenopathy w/ abnormal lung parenchyma
-50% resolution w/ no treatment
III-No lymphadenopathy w/ abnormal lung parenchyma
-20% resolution w/ no treament
IV-Parenchymal changes w/ fibrosis and architectural distortion
Gene associated w/ pulmonary arterial hypertension
BMPR2; associated w/ worse prognosis
Other syndromes associated w/ PAH
AI disease: RA, lupus, Sjogrens
Connective tissue diseases: Systemic Sclerosis, CREST
Liver disease: Due to decreased clearance of vasoactive substances
HIV, HCV
Dasatinib, imatinib
Last medication to try in patient’s with a severe asthma exacerbation
Mag sulfate
Shown to decrease bronchial constriction
TPA for PE in code
50mg over one minute
Intubation check list
Suction
Oxygenation
Airway (tube)
Pharmacy (etomidate 20 or 10 + succinylcholine or vecuronium if hyperkalemia or renal dysfunction)
