NORMAL VAGINAL FLORA DISCharge HEALTHY VAGINA IS AN ECOSYSTEM DYNAMIC EQUILIBRUM EXIXTS BETWEEN Epithelium Normal Colonizing Organisms (mostly Lactobacilli SPP) Local Secretory and Celluar Immune Factors Vaginal pH maintained o Acidic(3.8-4. 4) o Creates unfavourable environment for Pathogens
NORMAL VAGINAL FLORA & DISCHARGE HEALTHY VAGINA IS AN ECOSYSTEM DYNAMIC EQUILIBRUM EXIXTS BETWEEN: - Epithelium - Normal Colonizing Organisms (mostly Lactobacilli SPP) - Local Secretory and Celluar Immune Factors - Vaginal pH maintained o Acidic (3.8 – 4.4) o Creates unfavourable environment for Pathogens
NORMAL PH MECHANISM Estrogen increases Epithelial Glycogen Lactobacilli Metabolise Glycogen into Lactic Acid Lactic Acid maintains acid pH
NORMAL pH MECHANISM • Estrogen increases Epithelial Glycogen • Lactobacilli Metabolise Glycogen into Lactic Acid • Lactic Acid maintains acid pH
SIMPLE OFFICE ANALYSIS pH-litmus/nitrazine paper (nitrazine turns blue) Whff test-10% KOH-2 drops Microscopy -Wet mount, WBCS. Trichomonas, Monilia If no microscope available o Add hydrogen peroxide 1-2 drops of 5-10% KOH o Foaming bubbles if there are WBCS Wooden stick o No bubbles if no WBCs(BV for mixing under Yeast the nose 1-2 drops of vaginal
SIMPLE OFFICE ANALYSIS • pH – litmus/nitrazine paper (nitrazine turns blue) • “Whff” test – 10% KOH – 2 drops • Microscopy – Wet mount, WBCS, Trichomonas, Monilia • If no microscope available o Add hydrogen peroxide o Foaming bubbles if there are WBCs o No bubbles if no WBCs (BV, Yeast)
PATHOLOGIC VAGINAL DISCHARGE Common causes in lower genital tract 1)Bacterial vaginosis 2)Candidal vulvo vaginitis 3) Trichomonas vaginalis Bacterial Vaginosis Affects 25% of women 50% of women asymptomatic Commonest cause of vaginal complaint. Specific trigger not known, but BV related to o Intercourse- especially new partner, sexual aids o Spermicides, douches o Other infections

BV DIAGNOSIS )Gray homogenous discharge adherent to vaginal walls -no erythemaledema 2) pH akaline(over 4.5) 3)Presence of"Clue cells o Cells studded with bacteria o Cell wall indistinct 4)Fishy amine odor when 10% KOH added(TV, semen also causes odor releases 5)Paucity of lactobacilli 6)Relative absence of WBCs
BV DIAGNOSIS 1) Gray homogenous discharge adherent to vaginal walls – no erythema/edema. 2) pH akaline (over 4.5) 3) Presence of “Clue cells” o Cells studded with bacteria o Cell wall indistinct 4) Fishy amine odor when 10% KOH added (TV, semen also causes odor releases. 5) Paucity of lactobacilli 6) Relative absence of WBCs
