ABNORMAL VAGINAL DISCHARGE Leukorrhea - Definition: Excessive normal vaginal discharge - Normal fluid: Watery, white, non-odorous, pH 4.0, contains Doderlein bacilli Leukorrhea Criteria must know: - Excess secretion causing vulvar moistness or staining undergarments - Nonpurulent, nonoffensive, nonirritant, never causes pruritus Classification of Abnormal Vaginal Discharge: Type Features ---------------- Noninfective Nonpurulent, nonoffensive, nonirritant → Leukorrhea Infective Purulent, offensive, irritant Neoplastic - Foreign body - Causes of Physiologic Leukorrhea: - Puberty - endogenous estrogen excess - Menstrual cycle - peak at ovulation cervical glands, premenstrual endometrial glands - Pregnancy - hyperestrinsim + increased vascularity - Sexual excitement - Bartholin's gland secretion Life Table of Abnormal Discharge HIGH YIELD: Period Probable Diagnosis --------------------------- Early neonatal Leukorrhea Pre-menarchal Ill health, foreign body, threadworm Puberty Leukorrhea Reproductive non-pregnant Leukorrhea Pill users Leukorrhea, Moniliasis During antibiotics Moniliasis Diabetes Moniliasis Pregnancy Vaginitis moniliasis Postmenopausal Senile vaginitis, Pyometra, Neoplasm Treatment of Leukorrhea: - Improve general health - Local hygiene - Cervical lesions - electrocautery, cryosurgery, or trachelorrhaphy - Treat specific infection --- 2.
