Negative for bacterial vaginosis, meaning that the test results do not reveal signs of bacterial vaginosis. If at this time there is no discomfort and no change in the color or smell of the leukorrhea, in most cases it means that the vagina is not infected, so no special medication is needed. At this time, you should pay attention to keep your vulva clean and dry, change your underwear regularly, and try to choose cotton and breathable underwear. You should also pay attention to menstrual hygiene and change your sanitary napkins regularly to avoid prolonged non-replacement of sanitary napkins which may cause dampness in the pubic area and bacterial growth and induce vaginitis. If you go to the hospital because of uncomfortable symptoms such as vulvar itching and change in color and smell of the leucorrhea, and after a series of tests, you find that a negative bacterial vaginosis test only means that bacterial vaginosis is ruled out, and you need to consider several other vaginal inflammatory diseases, the more common ones being mycosis fungoides, trichomoniasis and senile vaginitis, as follows: 1. Mycosis fungoides: the patient’s vaginal discharge is white thick The vaginal discharge is white and thick, curd-like, bean curd-like or watery thin leucorrhea, redness and itching of the vulva, burning sensation in the vulva, painful intercourse and painful urination in some patients, and odor of leucorrhea in a few patients. Patients can be treated with oral fluconazole as prescribed by the doctor. In severe cases, glucocorticoid ointment can be applied externally, or local application of miconazole nitrate suppositories or clotrimazole suppositories. 2. Trichomonas vaginitis: The main manifestations are increased vaginal discharge and itching of the vulva and vaginal opening, with discharge typically characterized as thin or purulent, foamy and odorous (a putrid smell). There may also be burning and pain in the genital area, and some patients have painful intercourse. Treatment with drugs (metronidazole and tinidazole) is the mainstay. 3. senile vaginitis: the main manifestations are vulvar itching, increased vaginal discharge, and yellowish watery discharge. It is mainly treated by local and systemic medication, estrogen supplementation (local estrogen ointment is generally recommended for elderly women, oral estrogen supplementation is not recommended), increasing vaginal resistance and thus inhibiting bacterial growth.
