Respi system oneliners
[1] Creola bodies
In Bronchial asthma, air way epithelium is sloughed into bronchial lumen in form of CREOLA BODIES
[2] Asteroid body or Schaumann body
Nonspecific birefringent crystalline bodies in sarcoid granulomas.
[3] PULMONARY HEMORRHAGE primary causes:
[A] Good pasture syndrome
[2] Microscopic polyangitis
[C] Idiopathic pulmonary hemosiderosis
[4] Hypersensitivity pneumonitis : Important examples :-
[A] Bagassosis = due to T actinomycetes from moldy bagasse (sugarcane)
[B] Bird fancier,s , breeder's , handler's lung = bird proteins from avian droppings.
[C] Farmers lung = T actinomycetes from moldy hey
[D] Malt workers lung = Aspergillus fumigatus from moldy barley
[5] Hypersensitivity pneumonits = Both type III and type IV hypersensivity reaction
[6] Caplan syndrome = Seropositive rheumatoid arthiritis + Progressive massive fibrosis
Initially it was described in coal workers but subsequebntly found in variety of pneumoconioses
[7] Byssinosis = (typical description to identify q) = is charecterised clinically by occasional in early stage and then regular (late stage) chest tightness toward the end of the first day of workweek (" MONDAY CHEST TIGHTNESS")
[8] Asbestosis usually affects lower lobe first then spreads upwards as disease becomes more severe whereas silocosis coal workers pneumoconiosis usually affects upper lobe.
[9] Presence of hilar lymphedenopathy or calcified hilar lymphnode " egg shell calcification" in a pneumoconioses is more suggestive of SILICOSIS among all other pneumoconiosis
[10] The single most useful clinical sign of the severity of pneumonia is ?
Ans = respiratory rate >30 /min [ref : hson]
Other scoring methods for severity of pneumonia= [a] CURB score [b] PORT risk class
[11] Guessing most likely etiological agent of pneumonia by radiological finding
[A] upper lobe cavity = tb
[B] pneumatocoele = s pneumoniae
[C] air fluid level = abscess = polymicrobial
[D] *** CRESCENT SIGN in lung = Aspergillosis
[12] Pneumonia + hyponatremia = legionella pneumonia
[13] Hecht's pneumonia= interstitial giant cell pneumonia = measeles
[14] Triads
SAMTER TRIAD = asthma + allergy + nasal polyposis
KARTARGENERS SYNDROME = situs inversus + bronchiectasis + sinusitis
[15] Friedlanders pneumonia = kleibsiella pneumonia = bulging fissure sign
