Syphilis Flashcards
syphilis bacteria type
Treponema pallidum –> spirochete (spiral-shaped) bacteria
how is Treponema pallidum bacteria spread
- through shedding lesions containing microbial particles during sexual contact
- placental transmission from infected mother to baby
systemic cmplx
blindness, paralysis, heart disease & death
why do systemic cmplx occur
d/t bacteria entering circulatory & lymphatic systems
1st stage
- painless, non-bleeding, oval-shaped ulcer/chancre at contact sites
- regional lymphadenopathy
1st stage ulcer healing duration
heals in ~3-12 wks
quick healing in 1st makes pt speculate what
thinking they’re cured although they’re still infected (lesion is just not present)
regional lymphadenopathy
Bacteria in lymphatic system causing infection & resulting inflm of lymph nodes (swollen lymph nodes)
2nd stage duration
up to 6 months
when does 2nd stage begin
6-8 wks post-infection
2nd stage characteristics
- maculopapular (spotty, pimple-like) rash on palms of hands & soles of feet
- patches on mucous membranes
- flat papules
- generalized lymphadenopathy
symptoms of 2nd stage
fever, malaise
2nd stage latent period
can last up to 50 yrs (pt asympt while advancing subclinically)
when does 3rd stage occur
~1-35 yrs after 1st infection (if untreated)
3rd stage characteristics
irreversible damage to bones, joints, CVS, and NS
bacteria can still be eradicated
