-bacterial vaginosis
-vulvovaginal candidiasis
-trichomoniasis
vulvovaginal candidiasis symptoms
pruritis, discomfort, dysuria, thick discharge(thick, clumpy), no change in pH
vulvovaginal candidiasis(VVC) microbiology
-disruption of host vaginal enviorment
-excessive yeast growth
vulvovaginal candidiasis(VVC) predisposing factors
-pregnancy
-high dose oral contraceptives
-estrogen therapy
-history of diabetes
-antibiotics
-immunosuppressed
Self screening kits
-used to identify elevations in pH
-NOT a diagnostic tool
-elevated pH>4.5 needs referral
-pretty accurate
Limitations of self screening kits
-must wait72 hours after using any vaginal preparation(spermacide, antifungal)
-must wait 48 hours after sexual intercourse

uncomplicated VVC
-sporadic/infrequent
-mild to moderate symptoms
-likely to be C. albicans
-non-immunocomprimised
-Responds to short course treatment
Complicated VVC
-recurrent(>3 episodes/year)
-severe symptoms
-non-albicans candidiasis
-VVC in pregnant women, uncontrolled diabetes, immunosuppressed
-Should be evaluated by PCP. May need longer course of treatment/systemic treatment
Exclusions for self care of VVC
-pregnancy
-<12
-concurrent fever or pain in pelvis
-medications such as corticosteroids and antineoplastics
medical disorders(diabetes, HIV)
-recurrent VVC
-first episode
-bacterial vaginosis or trichomoniasis
OTC treatments of VVC
-vaginal antifungals(clotrimazole, miconazole, tioconazole): comes as cream, suppositories, tablets
Vaginal antifungal MOA
Alter fungi membrane permeability through decreased synthesis of
the fungal sterol ergosterol
duration of treatment for VVC
1, 3, or 7 days depending on treatment
Adverse effects of antifungals
-uncommon and generally mild
-burning, itching, irritation
-penile irritation and allergic reactions

-possible interactions between miconazole suppositories and warfarin
Which antifungals should be used during lactation?
miconazole or clotrimazole
Application of vaginal antifungals

yes. Continue as normal
Is it ok to have sex while using a vaginal medication?
No. wait 3 days
Non pharmacologic VVC
-sodium bicarb sitz bath
-prevention: yougurt(1 cup/day of live culture), decrease dietary sugars and refined carbs

-quick, temporary relief of vulvar irritation
-1 tsp of NA bicarb to 1 pint water
-Add 2-4 T. to 2 inches of bath water
