Medicine- Day 3

First full patient workup today. I learned that gathering information is easier if I know what I’m looking for . There are many sources of information, so it’s a good idea to prioritize my needs so that I don’t run out of time looking through different sources. It became a much more fulfilling experience as I gathered more information and was able to form a bigger picture of the patient.

Discussion topic: Pneumonia ( extra info)

  • PSI is validated, CURB-65 is not
  • blood cultures are more useful when: pt is alocholic, increase risk of non std bug suspected, low WBC
  • atypicals and anaerobic bacterias don’t grow in cultures
  • Atypical: Legionnella, K pneumoniae, C. pneumoniae, RSV (virus)
  • pneum vaccine repeat needed after age 65, or a 2nd dose may be required at least 5 years afterewards if first vaccination after 65 years of age
  • aspirational pneumonia likely in pt with: poor swallowing reflex, seizure, intubation, collapse
  • Antipseudomonas FQ: cipro, levo
  • moxi –> PO/IV, high bioavaliability
  • differential diagnosis: VQ scan ( pulmonary embolism), COPD, CHF

Bacterias that cause pneumonia: S. pneumo, M. Pneumo, C. pneumo, staph aureus, pseudomonas, viral, H. influenza, Legionnella

Atypicals that cause pneumonia: Legionnella, M. pneumo, C. pneumo, RSV

Bacterias that cause pneumonia in ICU patients: gram negatives, pseudomonas, MRSA,
