Disorders of the Vulva and Vagina Flashcards
pH ranges in vaginitis
Premenopausal women—pH = 3.5– 4.5 Trichomoniasis—pH = 5.0-6.0 Bacterial vaginosis—pH >4.5 Candidial infection—pH = 4.0 – 4.5 In pregnant women amniotic fluid raises the pH
Bacterial Vaginosis
Most common cause of discharge of women of childbearing age (40-50%)
Abnormality of the normal vaginal flora:
Decrease in hydrogen-peroxidase lactobacilli
Increase in primarily gram negative rods
Bacterial Vaginosis Findings on exam:
Fishy odor
Clue cells
Thin, white/gray, fishy smelling discharge
Amsel criteria for dx of BV
At least 3 of the 4 criteria
Homogeneous, thin, grayish-white discharge that smoothly coats the vaginal walls
Vaginal pH > 4.5
Positive whiff-amine test
Clue cells on saline wet mount, comprising at least 20% of epithelial cells
Vulvovaginal Candidiasis
Second most common cause of vaginitis symptoms and accounts for 1/3 of vaginitis cases—not an STI
Primary etiologic agent: Candida albicans, C. glabrata accounts for the remainder
More common in those on OCP’s or DM or immunocompromised
cottage cheese like discharge
Vulvovaginal Candidiasis Complicated infection Treatment
Fluconazole
Topical therapy w/ clotrimazole/miconazole/terconazole
Intravaginal boric acid tablets for 2 weeks (FATAL IF SWALLOWED)
Flucytosine cream intavaginally
Trichomonas Vaginitis
Most common STI WORLD wide
Flagellated protozoan—Trichomonas vaginalis is the causative organism
Infects both females and males
Trichomonas Vaginitis Presentation
Malodorous, thin, green/yellow vaginal discharge (70%) can also be frothy
Burning, dysuria, frequency (urethra commonly involved also)
Pruritus, dyspareunia, pelvic discomfort
Post-coital bleeding
Get “strawberry” cervix
Trichomonas Vaginitis Treatment
Tinadazole (Tindamax) or metronidazole (Flagyl)
Codylomata acuminata (anogenital warts)
MOST common viral sexually transmitted disease in the U.S.
Etiologic agent: HPV—serotypes 16 & 18
Atrophic Vaginitis Clinical manifestations
Vaginal dryness, burning or itching
Decreased lubrication during sex
Dsypareunia
Vulvar or vaginal bleeding (postcoital bleeding)
Vaginal discharge
Pelvic pressure or vaginal bulge
Urinary tract symptoms—frequency, dysuria, hematuria
Lichen Sclerosis
Etiology may be linked to genetics, autoimmune
Pathophysiology: Intense inflammatory reaction
Two peaks—prepubertal girls & postmenopausal women
Vulvar pruritus is the hallmark and may be so intense as to interfere with sleep
Treatment for lichen sclerosis
clobetasol propionate 0.05% cream for 6-12 weeks (topical steroids)
Marsupilization:
Done under local anesthesia
Longer procedure
Reserved for patients who fail 1-2 placements of a Word catheter
Complications: hematoma, scarring, dyspareunia
Paget’s Disease
Intraepithelial adenocarcinoma
Extramammary disease may involve genital, perianal and axillary areas
Lesions are brick red, scaly, velvety eczematoid plaque with sharp border
S/S: itching, burning, bleeding
Treatment: excision with > 3 mm border from visible margin
