Added Info From Lectures Flashcards
How do the following parameters differ for a viral vs. a bacterial pneumonia:
• CXR
• Infiltrate
• WBC
CXR will show NO consolidation with viral infections, while consolidation may or may not be present in bacterial infection
Infiltrates will be mostly lymphocytic in viral infection, while in bacterial pneumonia PMNs are more prominent
WBC becomes much more elevated in bacterial than viral infection
Who do you typically want to give Osmeltavir (tamaflu) to even if they are already experiencing symptoms?
Someone hwo is Pregant, Immunocompromised, or is very sick.
What viral infections are known to be linked to Reye’s syndrome?
Chicken Pox and Flu
If someone presents with a severe viral pneumonia, what should be one of the first drugs you treat them with?
Treat people who have severe pneumonia with vancomycin or Pip/Tazo just to cover for a secondary bacterial infection (b/c if you’re wrong about it being viral they’ll die)
What should you consider if you want to do PCR on flu, RSV, parainfluenza, coronaviruses or Adenovirus?
You will have to use reverse transcriptase (RT) on all RNA viruses like RSV, Flu, Corona, Adeno.
What are the two most common types of pneumonia to follow a viral flu infection?
S. Pneumococcus and Staph Aureus are the most common bacteria to follow a viral infection.
Which of the viral pneumonias could cause you to have a low hematocrit?
SARS because it causes thrombocytopenia and thus could cause peripheral bleeding.
What is the most important determinant of whether you will get TB?
Adequacy of cell mediated immunity
Someone has a positive PPD test, what should you do before intitiating treatment of latent TB?
Do a CXR to make sure its not reactivated
Would you expect someone with miliary TB to have a high AFB load in their sputum?
• Why or why not?
No, because the infection is not forming the cavitations like you see in secondary reactivated TB
What are two common bacterial infections to get following a flu infection?
Staph. a. and strep. pneumo
What will you cultures look like for atypical pneumonia?
Typically cultures are negative
