L20 urethritis and trichomoniasis Flashcards
what do you tx w/ PID
infection + inflammation
c. trachomatis dx
gold standard is isolation in cx
more sensitive is nucleic acid probes
vag candidiasis presentation
thick, white, frothy, non odorous discharge
itching
irritation
burning during sex/ urination
vag pain
risk factors for bacterial vaginosis
hx of STDs
sexually active
IUD
prior pregnancy/ abortion
trichomoniasis presentation
M- asymptomatic, +/- slight clear discharge
F- frothy malodorous discharge that can create an environement for further infection of bacterial vaginosis
trichomonas vaginalis morph
flagellate protozoa
extracellular anaerobe
trophozoite only
c. trachomatis presentation
M- uretritis, watery discharge
F- cervicitis, salpingitis, PID
baby- conjunctivitis
lypmhogranuloma
complications of repeat/ chronic salpingits/PID
by c. trachomatis
sterility
ectopic pregnancy
baby can catch (conjunctivitis/ PNA)
trichomonas tenax is in
mouth
usual causes of PID
n. gonorrhea
c. trachomatis
presentation of PID
lower ab pain
discharge
painful intercourse
fever/ chills
scarring
dysmenorrhea
dx of bacterial vaginosis, needs to have 3 of these things:
homogeneous secretions
clue cells
fishy amine odor when KOH is added
pH > 4.5
curved gram negative or gram variable rods
psittacosis =
chlamydiophyila psittaci
(chlamydia)
chancroid presentation
painful, bleeding, soft ulcer that develops quickly
gets bigger and more sprout up
bubo (painful inguinal LAD)
trichomonas dx
wet mount- common
cx- sensitive
MAB
DNA probe
trichomonas hominis is in
intestine
what kind of person presents w/ chancroid
tropical country
male (F- asymptomatic)
common species of vulvovaginal candidiasis
albicans (80-90%)
tropicalis
glabrata
PID dx
fever
leukocytosis
high ESR
clinica presentation (can be inaccurate)
clamydia trach infectious form
elemenary body
etiology of chancroid
haemophilus ducreyi
chancroid dx
difficult b/c bubo is sterile and sometimes many organisms in the chancre
media needs growth supplements
PCR based method available
chlamydia trach intracellular form
reticulate body
not an STD
bacterial vaginosis
can be grow in environment created by STD though (trichomonas vag)
chalmydia trachomatis morph
gram neg
need host ATP (obligate intracellular)
protein scaffolding of infected cells cllapse causing mucosal cells to separate
c. trachomatis
