Vulvovaginal pseudomonal yeast disease (V V V C) is a common vulvovaginal inflammatory disease caused by Pseudomonas aeruginosa. Foreign studies show that about 75% of women have had one episode of VV C in their lifetime, and 45% of women experience two or more episodes. Symptoms include itchy, burning vulva, frequent urination, painful urination and painful intercourse, and in some cases, increased leucorrhea. Typical leukorrhea is pea-like or curd-like and has no specific odor. The diagnosis can be confirmed by finding pseudofilamentous yeast in the leucorrhea examination. If there are symptoms and the test is negative several times, culture method can be used. Treatment, if diabetes should be actively treated, timely discontinuation of broad-spectrum antibiotics, estrogen and corticosteroids. Wash underwear regularly, and wash used underwear, basins and towels with boiling water. Local medication can be given vaginally. Oral medication can be used for unmarried women who cannot tolerate local medication and for those who do not want to use local medication. Patients who are unfortunate enough to have recurrent vulvovaginal pseudomycosis (RVVC), which is symptomatic and mycologically confirmed VVC occurring four or more times in a year with an incidence of about 5%, can have a headache. Its antifungal treatment is a protracted battle, divided into initial and consolidation therapy. Drug selection is based on fungal culture and drug sensitivity testing, and consolidation therapy is given for six months after the initial treatment achieves fungal cure. And follow-up is given once in 7-14 days, 3 months and 6 months at the end of treatment, and fungal culture is recommended again in the latter 2 times. Even with this troublesome course of treatment adhered to, yet there are still some patients who still have to relapse. Patients with this disease should not worry too much, because the inflammation can always be treated, and there are no reports that this disease can become cancerous with repeated attacks.
