HYHO URI + Pneumonia Flashcards
What is the classic cough pattern?
deep inspiration –>
attempted expiration against a closed glottis that suddenly opens –>
forceful exhalation of air, secretions, foreign debris
What is the most common chronic cough in healthy, nonsmokers with a normal CXR?
Upper Airway Cough Syndrome
(includes allergic rhinitis, bacterial sinusitis)
What is the most sensitive/specific test for GERD?
24 hr esophageal pH monitoring*
first line tx of GERD: 4 wk trial of PPI (dx and tx)
*not required to make dx
When is an endoscopy useful for GERD?
no improvement on PPIs for 4 wk duration
Pt reports they have a productive cough with green colored sputum. Should you be thinking bacterial or viral based on their presentation?
not enough info yet –> color of sputum is not diagnostic of presence of bacterial infection
Should we give ABs with acute bronchitis?
they don’t provide major clinical benefit, and are not recommended routinely
only recommended for at risk pts, when clinical suspicion of CAP is high, or suspected B pertussis, mycoplasma or chlamydia infection
when should you suspect bacterial URI?
after 7 days in an adult, 10 days in a kid
What organisms are most commonly responsible for acute bacterial sinusitis?
adults: S pneumoniae and H. influenza
children: H. inf. and Moraxella catarrhalis
The majority of pharyngitis cases are?
viral
Modified CENTOR Criteria
- A guideline for diagnosing GAS without performing rapid Strep or throat culture.
-
A point is given for each of the following criteria:
- Absence of cough
- enlarged/tender anterior cervical adenopathy
- fever of 100.4 F or higher
- tonsillar swelling/exudates.
- One additional point is added if patient is b/t 3 and 14
- One point is deducted if patient is age 45+
- 0-1 points: recommend no further testing and no antibiotic indicated
- 2-3 points: perform rapid strep or throat culture and treat with antibiotic if positive
- 4+: consider empiric antibiotic treatment
Pt. presents with acute cough <3 wks +/- sputum, what is your next move?
What diagnostic testing is used to dx pneumonia?
- Leukocytosis with leftward shift or leukopenia.
- Elevated inflammatory markers (ESR, CRP, and procalcitonin).
- CXR
- CT (may be considered for immunocompromised patients)
What lab abnormalities are seen with s. pneumoniae infections? how do we tx?
a. elevated LFT’s, hyponatremia, leukocytosis
b. penicillin, macrolides, fluoroquinolones
What organism may cause empyema?
s. auerus
CA-MRSA
If a pt presents with hx of ab use in the past 3 mo, and sx of pneumonia, what should you be worried about?
MRSA
also worry if hx includes recent hospitalization or IC staus
