Vaginal discharge (leukemia) is one of the key complaints from patients in the practice of a gynecologist. This syndrome requires careful differential diagnosis, because diseases that manifest themselves with leukemia are not equal in their predictions, clinical significance and therapeutic tactics. The material describes the main causes of vaginal discharge, diagnostic approaches to them and The methods of treatment.

Bacterial vaginosis

Risk factors include the change of a sexual partner or more than three partners during the last year, douching, smoking.
Diagnostic criteria:
Treatment: drug of choice - metronidazole.
Dosage:
500 mg 2 times a day for 7 days OR
2 g once or
Metronidazole long-acting: 750 mg once a day for 7 days.
In pregnant women: 500 mg 2 times a day for 7 days OR 250 mg 3 times a day for 7 days.

Usually there is pronounced erythema of the vulva and vaginal mucosa. On the cervix of the uterus it is possible to detect pinpoint hemorrhages (a symptom of a strawberry neck).
Diagnostics:
Microscopy of a wet swab of vaginal discharge: detectable Trichomonas vaginalis.
Tests of amplification of nucleic acids and determination of antigens in vaginal discharge.
Gold standard: tothe vaginal discharge.
Treatment:
Metronidazole 2 g once. In addition to the patient, treatment should be prescribed to all sexual partners.

Candidiasis
Causal agent: Candida albicans.
Clinical picture: Typical complaints: itching and burning sensations in the vagina, dysuria, dyspareunia. Allocations are usually ungrowner, white, curdled. On examination, erythema and swelling of the vaginal mucosa are noted.
