VAGINAL INFECTIONS Flashcards
Normal vaginal ph
pH 3.8 to 4.5 is normal
Anything that disrupts the normal vaginal pH will lead to
infections of the genital tract!
o Alkaline pH (>4.5) will favor BACTERIAL VAGINOSIS and
TRICHOMONAS
o Acidic pH (<3.8) will favor fungi growth
CANDIDA
Describe the normal secretion of the vagina
white, floccular, odorless
Discharge: Gray-white
• Usually noted after
intercourse
Bacterial
Vaginitis
Discharge: Yellow-green bubbly
Trichomonas
Discharge: White, curd-like
Candida
Vaginitis
Discharge: Fishy
Bacterial
Vaginitis
What is the treatment for Bacterial Vaginosis?
Nonpregnant women: 500 mg BID x 7 days OR 2 g orally single dose
Pregnant women: 500 mg PO BID x 7 days OR 250 mg PO
TID x 7 days
Alternative: Tinidazole
Give the precautions of Metronidazole
do not take alcohol with
metronidazole to prevent the disulfiram-like reaction (nausea, vomiting, flushing, dizziness, throbbing headache, chest and abdominal discomfort, and general hangover-like symptoms among others)
Significance of having bacterial vaginosis in pregnant women
o Risk factor for PPROM
o Preterm labor
Bacterial Vaginosis
Etiology
Gardnerella
vaginalis
GIVE THE 4 CRITERIA in Diagnosis of BACTERIAL VAGINOSIS
Criteria for diagnosis: 1. Homogenous vaginal discharge 2. Discharge pH >4.5 3. Whiff test (+) – amine like odor 4. Clue cells > 20% of normal vaginal epithelial cells on wet smear
Diagnostics for Bacterial Vaginosis
WET SMEAR - clue cells (vaginal
epithelial cells with clusters of
bacteria adherent to the external
surfaces)
(+) Whiff test with KOH –> Amine like odor is observed
Why does bacterial vaginosis occur?
Occurs when anaerobic
bacteria predominate over
lactobacilli in the vagina
Etiology of Trichomoniasis
Trichomonas vaginalis
