Acute vulvovaginitis is characterized by swelling, congestion and erosion of the vulva, sometimes forming ulcers or patches of eczema. Patients are conscious of burning, itching or pain in the vulva, especially when urinating. In severe cases, the inguinal lymph nodes are enlarged and painful, body temperature may be slightly elevated, and leukocytosis. In diabetic vulvitis, the vulvar skin is red, thickened, often brown, with scratches. Because the urine sugar is conducive to mold growth and reproduction, it is often complicated by Candida albicans infection. In chronic inflammation, the vulva is itchy and mossy. The common causes of acute vulvar inflammation include: such as vaginal secretion stimulation (including vaginal secretion increased flow to the vulva stimulation, menstruation or menstrual pads, panties, etc. stimulation); other irritating factors (a. diabetic urine b. urogenital fistula patients long time impregnated by urine c. patients with intestinal cancer is sometimes stimulated by feces d. intestinal bypassing worms); mixed infections (the common pathogens staphylococcus streptococcus and Escherichia coli) etc. Common vulvovaginitis in women are mainly as follows: 1. Non-specific vulvovaginitis: Physical and chemical factors stimulation in life, not paying attention to hygiene, and physical weakness can make women’s vulva be infested by bacteria and cause vulvovaginitis, such as inflammation of cervix-vagina; or wearing impermeable nylon panties to make vaginal secretions excessively stimulate the vulva; impregnation of the vulva by urine; and vulvovaginal infections caused by the use of unclean sanitary napkins and handkerchiefs, etc., all of these factors All these factors will create conditions for bacteria to grow and multiply in the vulva. But because this kind of vulvovaginitis is not caused by specific pathogens, but mostly staphylococcus streptococcus, Escherichia coli and other mixed infections, so it is called non-specific vulvovaginitis. 2.Mycotic vulvovaginitis: vulvovaginitis caused by a kind of yeast infection, often coexisting with mycotic vaginitis. 3.Acute vulvar ulcers: mostly caused by various causes of vulvitis, generally a manifestation of vulvovaginitis in the course of lesions. Found to have vulvar skin itching, burning sensation and pain, in the activity of sexual intercourse and urination after aggravation, the acute phase of redness, congestion, scratching and other symptoms can be initially suspected after vulvovaginitis.
