VAGINAL DISCHARGE

VAGINAL DISCHARGE: Excerpt from Algorithmic Diagnosis of Symptoms and Signs

Ask the Following Questions:

1. Is it purulent? A purulent vaginal discharge suggests nonspecific bacterial vaginitis and gonorrhea.
2. Is it frothy and yellow? This type of discharge is very often due to trichomoniasis vaginitis.
3. Is it cheesy and associated with itching? These findings suggest candidiasis vaginitis.
4. Is it watery and bloodstained? This type of discharge suggests carcinoma of the cervix or endometrium, polyps, hydatidiform mole, and chronic cervicitis. If a frankly bloody discharge is noted, consult the differential diagnosis discussed on page 309 .
5. Is it offensive smelling? An offensive smelling discharge would suggest foreign body in the vagina.
6. Is there inflammation of the cervix? The presence of cervical inflammation would suggest chronic cervicitis and gonorrhea.

DIAGNOSTIC WORKUP

The most important test is microscopic examination of a saline and potassium hydroxide preparation. This will diagnose most cases of trichomoniasis and candidiasis. Gardnerella vaginalis can be diagnosed if clue cells are found, and the pH of the discharge will be greater than 4.7. If this is unrevealing, a Gram stain for gonorrhea and cultures for trichomoniasis, candidiasis, chlamydia, Gardnerella vaginalis , and gonorrhea may be done. A Pap smear should be done to rule out malignancy. Polyps or inflamed areas of the cervix should be biopsied. Colposcopy may help further differentiate a cervical lesion. A dilation and curettage may be necessary to diagnose endometrial carcinoma and hydatidiform mole. Occasionally, pelvic ultrasound and CT scans are necessary. However, before ordering these expensive diagnostic tests, a gynecologist should be consulted. Patients with documented evidence of gonorrhea should have a VDRL test and HIV testing.
