Infectious Disease Flashcards
four signs and symptoms of streptococcal pharyngitis
fever, pharyngeal erythema, tonsillar exudate, and lack of cough
non-suppurative complication of streptococcal infection that is not altered by tx of primary infection
post-infectious glomerulonephritis
most common predisposing factor for acute sinusitis

pseudomonas
osteomyelitis in a sickle cell pt
salmonella
3 most common causes of fever of unknown origin
infection, cancer, and autoimmune dz
PPD indurations that are considered positive in various pt groups…
> 5 mm = immunocomp. pts, recent contacts w/ known TB
10 mm = recent immigrants from TB areas, injection drug users, residents/employees of high risk settings, TB labs, children 15 mm = all pts
HIV pt w/ CD4 less than 200. bug? prophy?
PCP w/ TMP-SMX
HIV pt w/ CD4 less than 50. bug? prophy?
MAC w/ azithromycin
HIV pt w/ CD4 less than 100. bug? prophy?
toxoplasma gondii w/ TMP-SMX
CSF findings for bacterial meningitis? RBCs = ? WBCs = ? glucose = ? protein = ? opening pressure = ? appearance = ?
CSF findings for bacterial meningitis? RBCs = normal WBCs = increased (> 1000 PMNs) glucose = decreased protein = increased opening pressure = increased appearance = cloudy/purulent
CSF findings for viral meningitis? RBCs = ? WBCs = ? glucose = ? protein = ? opening pressure = ? appearance = ?
CSF findings for viral meningitis? RBCs = normal WBCs = increased (mono/lymph) glucose = normal protein = normal to increased opening pressure = normal to increased appearance = usually clear
CSF findings for aseptic meningitis? RBCs = ? WBCs = ? glucose = ? protein = ? opening pressure = ? appearance = ?
CSF findings for aseptic meningitis? RBCs = normal WBCs = increased glucose = normal protein = normal to increased opening pressure = normal appearance = clear
CSF findings for SAH? RBCs = ? WBCs = ? glucose = ? protein = ? opening pressure = ? appearance = ?
CSF findings for SAH? RBCs = increased WBCs = increased glucose = normal protein = increased opening pressure = normal to increased appearance = yellow to red
CSF findings for GBS? RBCs = ? WBCs = ? glucose = ? protein = ? opening pressure = ? appearance = ?
CSF findings for GBS? RBCs = normal WBCs = normal glucose = normal to increased protein = increased opening pressure = normal appearance = clear to yellow
CSF findings for pseudotumor cerebri? RBCs = ? WBCs = ? glucose = ? protein = ? opening pressure = ? appearance = ?
CSF findings for pseudotumor cerebri? RBCs = normal WBCs = normal glucose = normal protein = normal opening pressure = increased appearance = clear
triad of disseminated gonococcal infection?
polyarthralgias, tenosynovitis, and vesiculopustular skin lesions
