Respiratory (43) Flashcards
Dx:
distress, dysphagia, dysphonia, drooing
epiglottitis
“thumb sig” on XR
MCC of epiglottitis?
Hib
MCC of bronchiolitis in children
RSV
MCC of illness that causes “steeple sign” dt subglottic narrowing.
Croup, caused by parainfluenza virus
MCC of pharyngitis
- MC viral (rhino)
2. MC bacterial strep pyogenes (Grp A)
differentiating factor b/w viral v. bacterial pharyngitis
both fever –> bacterial if anterior cervical LAD and/or tonsillar erythema/exudates
What is the dx:
asthmatic pt with recurrent exacerbations of fever, cough, dyspnea. bronchiectasis (dilation of airways), causing expectoration of brown mucus plug. Peripheral eosinophilia
aspergillus - Allergic BronchoPulmonary Aspergillosis (ABPA)
dx first test for ABPA
skin prick for HSR
dx criteria for chronic bronchitis.
classic color on exam
> 3mo for 2 years in a row of productive cough, as well as evidence of airway obstruction on PFT (FEV1/FVC blue bloaters (fat, cyanotic)
major distinguishing factor b/w asthma and chronic bronchitis
asthma is reversible after bronchodilator therapy
CT imaging reveals expiratory trapping within bronchioles, bronchial wall thickening, gropund glass ocpacities thorught all lung fields. rare cause of cough in adults.
bronchiolotis obliteras (dt inflammation or fibrosis)
abnormal enlargement and permanent destruction of airspace distal to bronchioles iwth no evidence of fibrosis. common cause of chronic cough. non cyanotic, RR high, thin with inc AP ches diameter.
CT: large bullae, flat diaphragm, enlarged airspace.
emphysema
Cough, dyspnea, excess production of foul purulent sputum for mo-years. May complain of hemoptysis, dyspnea, pleuritic chest pain, wheezing, wt loss, fatigue. Not relieved by tx for pneumonia or obsructive lung diseases (asthma/bronchitis/COP)
CXR: dilated and thickened airways.
CT: airway dilatation and bronchial thickening in presence of mucus plugs or debris and post-obstructive air trapping “signet ring sign”
bronchiectasis
First step in management of children with epiglottitis
endotracheal intubation

Most appropriate first test for someone suspected to have AAT
genetic
child with hx of recurrent OM presents with new onset unilateral conductive hearing loss (weber localizes to bad, rinne: negative = bone conduction > air = sound not heard)). PE shows white mass located behind intact TM
congenital cholesteatoma
Middle age women complains of pulsatile tinnitus and gradual, painless hearing loss. Pulsating reddish-blue mass seen behind intact tympanic membrane
glomus tumors
weber: sound hear best in normal hear
rinne: positive = air>bone conduction = sound still heard
sensorineural hearing loss
dx: a single, discrete inhalation exposure
dx: multiple exposures
single = reactive airway dysfunction syndrome (RADS)
multiple = irritant-induced asthma

Give ampicillin for OM when?
only first line tx if middle ear inflammation or very severe infective sx
first line is supportive
MCC of hypercalcemia (bones, groans, abdominal moans, psychiatric overtones)
SCCa - MALIGNANCY (hyperCa = >10.2)
