Q

How might dexamethasone be helpful in children and infants >6 weeks with bacterial meningitis?

Study These Flashcards
A

To decrease hearing loss in patients with H. influenza meningitis (NOT NEONATES)

20
Q

What are IDSA indications for dexamethasone in the setting of pediatric meningitis?

Study These Flashcards
A
  • H. influenzae suspected, before antibiotics
  • Consider if s. pneumoniae and high risk of mortality
21
Q

What is the most common comorbidity that leads to CAP?

22
Q

What are the 3 routes of entry for pathogens causing CAP?

Study These Flashcards
A
  • Inhaled aerosolized particles
  • Through bloodstream
  • Aspiration
23
Q

What are the hallmark s/s of CAP that must be present for diagnosis?

24
Q

What is the gold standard for bacterial CAP diagnosis?

Study These Flashcards
A

Chest X-ray lobar or confuse consolidation in one lobe of the lung

25
How does a viral CAP infection look on a chest X-ray?
General haziness throughout both lungs
26
What diagnostics are rarely drawn/used for CAP?
- Blood cultures - Sputum cultures
27
Who should be hospitalized for CAP?
- Moderate-severe - Respiratory distress (O2 < 90%) - Infants <3 months - Infants <6 months with suspected bacterial CAP - Suspicion or documentation of MRSA - Caretaker capability concern - Underlying medical conditions
28
What is the best predictor of pathogen identification in CAP?
AGE
29
What is the most common pathogen for CAP across all age groups up to 15?
S. pneumoniae
30
T/F: Viruses such as RSV are significant causes of CAP in young children and infants.
TRUE
31
When do atypical bacteria begin to enter the suspected pathogen pool and become more common for CAP? (M. pneumoniae, C. pneumoniae)
5 years of age
32
When should CAP symptoms resolve with appropriate treatment?
2-3 days
33
What are the 1st and 2nd line treatments for outpatient bacterial CAP outpatient?
1. Amoxicillin PO 90 mg/kg/day in 2 doses 2. Augmentin PO 90 mg/kg/day in 2 doses
34
What is the first line treatment for presumed atypical CAP outpatient?
Azithromycin PO 10 mg/kg on day 1, followed by 5 mg/kg on days 2-5
35
T/F: Azithromycin and penicillins should not be used together to treat CAP.
FALSE: Azithromycin can be added on to the first line treatment if bacterial vs. atypical is ambiguous
36
What treatment should be used for inpatient CAP who is fully immunized and lives in an area where the local penicillin resistance is minimal (MIC <2)
Ampicillin IV* or penicillin G IV
37
What treatment should be used for inpatient CAP who is NOT fully immunized OR lives in an area where the local penicillin resistance is HIGH (MIC >2)
Ceftriaxone IV* or cefotaxime IV
38
Why do we use high dose amoxicillin/augmentin to treat CAP?
To overcome s. pneumoniae mechanism of resistance - penicillin-binding proteins
39
What does the clavulanate offer in augmentin?
Coverage of B-lactamase producing organisms (H. influenzae)
40
Why is the ES formulation preferred for high-dose augmentin/amoxicillin?
To minimize supratherapeutic concentrations of clavulanate
41
Why does azithromycin have such a short treatment course?
Its long half life produces a post-antibiotic effect
42
Why is ceftriaxone used in un-immunized children?
Concern for H. influenzae (B-lactamase-producing)
43
What is the viral influenza treatment that should be used within 48 hours of symptoms to be effective?
Oseltamivir - 5 day course
44
What is the IDSA recommended treatment duration for CAP?
10 days
45
What should you switch to if a patient has a non-serious penicillin allergy?
Trial under medical supervision: - Cephalosporins such as cefpodoxime, cefprozil, cefuroxime
46
What should you switch to if a patient has a history of anaphylaxis to penicillin?
- Levofloxacin - Linezolid - Macrolide - Clindamycin - Bactrim
