Vaginal Infections, STIs, Vulvar Conditions Flashcards
(111 cards)
bacterial vaginosis definiton
alteration of the normal vaginal flora of the vagina with dominance of anaerobic bacteria (not enough of that good Lacto B)
etiology of BV
-loss of lactobacilli results in elevated pH and subsequent overgrowth of bacteria
-NOT an STI, however more common in women with new partners
-BV may increase risk for acquiring HIV or HSV 2
-may be asx with pp, post op infection, endometriosis, PID
symptoms of BV (4)
-odor, color
-most often asymptomatic
-pruritis occasionally
-heavy grayish/yellowish/whitish malodorous discharge
-rancid or fishy odor during menses and after sex
physical findings of BV
- homogenous, aderent, whitish-gray discharge
- normal appearing vulva and vaginal mucosa
- discharge may coat vaginal walls and vulva
- presence of foul odor
diagnostic tests/findings for BV
-wet mount of vaginal secretions
Amsel criteria diagnostic of BV include presence of three of the following:
a. vaginal pH > 4.5
b. clue cells on saline wet mount (epithelial cells with borders obscured); > 20% of epithelial cells are studded
c. homogeneous discharge, white, smoothly coating vaginal wall
d. positive “whiff” test- fishy amine odor of vaginal dc with addition of KOH
treatment of BV includes
-Metronidazole (Flagyl) 500 mg BID for 7 days
-Metronidazole gel 0.75%, one full applicator intravaginally at bedtime for 5 days
-Clindamycin cream 2%, one full applicator intravaginally at bedtime for 7 days
alternative regimens:
-Clindamycin 300 mg orally BID for 7 days
what should we counsel patients regarding metronidazole use?
can cause disulfiram effect (flushing, vomiting) when consumed with alcohol; counsel patient to avoid alcohol use during and for 24 hours after completion
SE: metallic taste, nausea, headache, dry mouth, dark-colored urine
Trichomoniasis definition
vaginal infection caused by anareobic, flagellated protozoan parasite
T/F trichomoniasis infection may be associated with preterm rupture of membranes and preterm labor
TRUE
why we test and treat in pregnancy/at amenorrhea visit
symptoms of Trich
-copious, malodorous, yellowish-green discharge; vulva irritation; pruritis, and occasionally dysuria, urgency, frequency of urination, post coital and intermenstrual bleeding
-onset of symptoms occur after menses
physical findings of patients with trich
-erythema, edema, excoriation of vulva
-red speckles “strawberry cervix” on vagina and cervix
-homogeneous, watery, yellow-green, grayish, foul smelling discharge
-ph>5
-cervix may bleed easily when touched
diagnostic tests for trich
-saline wet mouth
-definitive test: culture
-detection on pap ok too
treatment of trichomoniasis
- metronidazole 2g orally in a single dose (male)
- metronidazole 500 mg BID for 7 days (female)
- Tinidazole 2 g orally in single dose
T/F trichomoniasis is not an STI so partners don’t need to be treated
false babe!!!
all sexual partners should be treated
when should repeat testing be done? what if treatment failure has occured?
in 3 months
-exclude reinfection, consider treatment with metronidazole or tinidazole 2g orally for 7 days
treatment of trich in pregnancy (1)
- metronidazole 2g PO in single dose
*NOTE: crosses the placenta BUT no teratogenicity effect found
vulvovaginal candidiasis (VVC)
-predisposing factors??
inflammatory vulvovaginal process caused by yeast organism
predisposing factors to yeast infections: pregnancy, reproductive age, uncontrolled diabetes, immunosuppressive disorders, frequent intercourse, antibiotic use, high-dose corticosteroids
symptoms and physical findings of yeast infection
-pruritis/irritation of vulva
-white, curd-like discharge
-dyspareunia
-erythema of vulva and vagina
-cervix normal on speculum exam
diagnostic tests
wet mount of vaginal secretions
-vaginal pH usually < 4.5; amine test neg
-increased number of WBC (since its an inflammatory process)
recommended regimens for yeast infections
-azole family of antifungals preferred
- Clotrimazole 1% cream, 5g intravaginally daily for 7-14 days
- Miconazole 2% cream, 5g intravaginally for 7 days
- Miconazole 4% cream, 5g intravaginally for 3 days
- oral agent: fluconazole 150 mg orally in single dose
treatment for recurrent VVC in nonpregnant patients
-how many episodes is considered recurrent
-4 or more symptomatic episodes in one year
- culture to determine if non-albicans candida species
- consider longer-duration therapy: 150 mg oral fluconazole every 72 hours for 3 rounds
- consider use of intravaginal probiotics
treatment of VVC in pregancy
- monistat OTC
- Miconazole 2% cream, in the vagina for 7 days
- Nystatin suppository for 14 nights
OVERALL: avoid oral agent for VVC in pregnancy!
key point regarding use of azole creams an suppositories since they are oil-based…
may weaken latex condoms and diaphragms
