infectious disorders of the female GU Flashcards
vaginitis
inflammation or infection of the vaginal canal, often in conjuction with vulvar irritation.
normal values
discharge: 1.5 gm
pH: 3.5-4.5
group B strep. lactobacillus predominant
sxs of vaginitis
change in flora, change in pH, change in discharge, inflammation. itching, burning, irritation, contact with dc is uncomfortable. odor, color/consistency
candidiasis
yeast infection. predisposed by: DM, recent abx use, OCPs, pg, coricosteroid therapy, occulusive clothing.
sxs candidiasis
white, thick dc. intense itching, dysuria (as flow touches labia). signs: vulvar/labial erythema, excoriation, edema, white dc often without odor
dx of candidiasis
characteristic signs and symptoms, normal pH, hyphae/spores on KOH, wet prep or culture
tx yeast infection
antifungal therapy-topicals (miconazole) qhs for 7 days. oral (fluconazole) 150 mg PO 1 dose. Resistant terconazole qhs 3-7 days. OTC
bacterial vaginosis
common cause vaginal dc in women of childbearing age.
etiology of BV
overgrowth of largely anaerobic bacteria, decrease or absence of lactobacillus. increased gardnerella. STI, douching, vag irritants, smoking
sxs of BV
non-irritating dc-multimicrobial. thin gray-white/yellow dc; foul fishy odor.
dx of BV Amsel criteria must have 3
abnormal dc, abnormal pH (>4.5), + whiff test with KOH, wet prep shows clue cells, DNA probe
tx of BV
antibacterial (anaerobic) metronidazole either vaginally o PO. oral or topical clindamycin
Trichomoniasis
wet mount shows increased PMNs with motile flagellate. KOH: whiff. pH >4.5. DNA probe. strawberry spots on cervix. Screen for other STIs
tx of trichomoniasis
systemic metronidazole for both pt and partner. screen for other stis.
wet prep
normal saline added to dc on a slide. visualize trichomonas, clue cells, yeast
