PULM and Allergy/Immuno Flashcards
(44 cards)
Types of CA
Small Cell
Squamous Adeno Large Carcinoid Mesothelioma
Small Cell - ACTH, ADH, Lambert E, L myc, Kulchitsky cell. Bombesi, chromogranin+. Poorly diff neuroendocrine>
Squamous- PTHrp _ Central cavitation, Keratin, pearls, intercellular bridges
Adeno - Peripheral - most common overal - K-Ras - Short plump microvilli
Large
Carcinoid - polyp like mass in the bronchus - Well diff neuroendocirne - Nonsmoking, related. Chromogranin +
mesothelioma - recurrent hemorrhagic pleural effusion - Long villi. Psamomma body.
Sarcoid finding
What to not confuse this with?
Sarcoid - noncaseating granulomas - ICN ACE, Ca, can mimic sjogrens. E nodosum.
dont confuse w/ berylliosis! Which is also noncaseating granulomas!
Asbestos - findings?
Pleural plaques - ferruginous bodies - Fe
Sililicosis findings -
M! dysfunction - INC risk of TB - pper lobe eggschell calcifications of hilar LAD
Anthracosis
Asx - urban dweller
Nasopharyngeal CA findings
monitoring?
Epistaxis, otitis media.
Monitor EBV titers for tx responsiveness
Obsturctive PFT fidigns
Emphysema vs Chronic Bronchitis?
FEV1/FVC is LESS THAN 80% predicted.
Emyphsema - DEC DLCO (destroyed alveoli)
Chronic Bronhchitis - DLCO is normal
Tx COPD exacerbation vs Asthma?
COPD - O2, Ipra, Steroids, ABX! -»PPV, Intubate.
Asthma - similar - O2, Ipra, steroids. NO ABX.
Pharm causes of Restrictive Diseaes and PFT?
Restrictive - FEv/FVC > 8-%.
Drug - Bleomycin, busulfan, amiodarone, methotrexate.
Solitary mass - algorithm?
Past X ray.
Neg -> Ct
Okay looking - serieal CT
Suspicious - Surgical excision
PE pressure measurements?
What ABG findings?
S1Q3T3
INC RA, pulm artery pressure.
NORMAL WEDGE.
ABG - INC A-a gradient . (Normal alveoli, DEC arterioles)
Empyema - most convincing finding?
pH > Gluocse
Lights criteria
Tranduse -Low - CHF, Cirrhosis
Exudate - INC - PE, CA, Infection
Bronchial rupture
vs
Diaphgramatic rupture
Both are post traumatic
Bronchial rupture - persistent PTX
Diaphgramatic rupture - NG in pulm space
Neonatal RDS - Tx?
Steroids, T4, Prolactin
Longstanding complciatiosn of neonatal ARDS?
Tx?
N! dmg -> T2 stem cell dmg -> fibrosis
Protein rich, pink/fibrin. NORMAL pulm wedge! BUT INC poulm artery .
Tx - low tidal, INC PEEP. But INC PTX risk
Bronchogenic cyst location?
Middle mediastnial mass.
Tx for aspirin induced athma?
Montelukast
LTR antagonist
TB exudate findings
HIGH PROTEIN CONTENT (Greater than 4),LYMPHOCYTIC leukocytosis. No gross purulence! (compared to other infectious exudates.
Pulmonary contusion
– after trauma – delayed in development – up to within first 24 hours. Tx- conservative w/ pain control and maintnence of pulm toilet until bloody fluid cleared./
Angioedema (hereditary tx) - c1 esterase inhbitor def.
Intubate (if needed)
Acute:ECALLANTIDE or FFP
Long term - androgens (Danazole, Stanazole)
When Asx, best way to test for asthma?
> 20% def in FEV1 w/ methacholine use . WHEN ASX
Best test for dx Bronchiectasis?
High res CT scan
Major cuase of death in CF?
lung pathology
