Diagnostic criteria for bacterial vaginosis

Mycorethritis is an inflammatory lesion of the urethra caused by fungi. Fungi exist in the normal human body, usually in the skin, oropharynx, colon, vagina and other parts. So how do we identify and diagnose the several types of mycotic urethritis? The following are the identification and diagnosis methods of several types of vaginitis.

Trichomonas vaginitis

Trichomonas vaginitis is a common vaginitis caused by Trichomonas vaginalis.

Increased leucorrhea and vulvar pruritus The main symptoms of trichomonas vaginitis are increased thin foamy leucorrhea and vulvar pruritus. If there is a mixed infection with other bacteria, the discharge is purulent and may have a foul odor. The itching sites are mainly the vaginal opening and vulva, and there may be burning, pain, and sexual intercourse pain. If the urethral opening is infected, there may be frequent urination, dysuria, and sometimes hematuria. During the examination, the vaginal mucosa is congested. In severe cases, there are scattered bleeding spots. There is a large amount of leucorrhea in the posterior fornix, which is gray-yellow, yellow-white thin liquid or yellow-green purulent secretions, often foamy. There may be no abnormal findings in the vaginal mucosa of carriers. A small number of patients have trichomonas in the vagina without inflammatory reactions, which are called carriers. Some people believe that trichomonas cannot cause inflammation when it exists alone, because it consumes glycogen in vaginal epithelial cells, changes the pH of the vagina, destroys the defense mechanism, and promotes secondary bacterial infection. Therefore, it often causes inflammation when the vaginal Ph changes before and after menstruation, during pregnancy or after childbirth.

Bacterial vaginosis

Bacterial vaginosis is a type of vaginitis caused primarily by Gardnerella vaginalis and can be transmitted through sexual intercourse.

The typical clinical symptoms of this disease are a significant increase in abnormal vaginal secretions, which are thin and homogeneous or thin and paste-like, grayish white, grayish yellow or milky yellow, and have a special fishy odor. Since alkaline prostatic fluid can cause the release of amines, the odor worsens during or after sexual intercourse. The pH value of the vagina increases during menstruation, so the odor may also worsen during or after menstruation. The patient has discomfort in the vulva, including varying degrees of vulvar itching, which generally has no obvious time limit, but the itching is more obvious when resting or under stress. There is also a varying degree of burning sensation when taking external medicine, and some patients experience dyspareunia. A very small number of patients experience lower abdominal pain, difficulty in sexual intercourse, and abnormal urination. The vaginal mucosal epithelium does not show obvious congestion at the onset of the disease.

Amebic vaginitis

Amebic vaginitis is mostly caused by amebic pathogens being excreted in the stool and directly infecting the vulva or vagina.

Vaginal secretions are serous or mucous, and large trophozoites can be found in them. When the vaginal mucosa forms ulcers and bleeds, the secretions may become purulent or bloody. Sometimes brittle ulcers may appear on the cervix and vulva, merging into large pieces of necrosis. In some cases, due to severe connective tissue reactions, irregular tumor-like hyperplasia may occur, with a hard texture and bloody mucous secretions covering the ulcer surface, which can be easily misdiagnosed as malignant tumors.
