Xiaohong and Ah Wen are a pair of good sisters, working in a foreign company, also married in pairs last year. A Wen and Xiao Hong, since childhood is very clean, after the family room is also immaculate, cleaned up in order, clean. The two of them, because of the good relationship, together to tell, often feel the lower body secretion of foreign matter increased, they go to the pharmacy to buy a variety of drugs, repeatedly wash the vulva, but also according to advertising which brand of health care cleaning fluid, regardless of the buy to try, but are very unsatisfactory, sometimes good, sometimes bad, coupled with the recent period of time, the lower body discomfort symptoms aggravated, leucorrhea increased odor, the two of them with confusion into the Yang director of gynecology She came into the gynecology clinic with confusion. After careful examination and laboratory results, Wen was found to have “trichomoniasis” and Xiao Hong had “fungal vaginitis” (Candida vaginitis). What’s going on here? First, the structure of the female pubic area determines that women are very vulnerable to various germs, and the air, objects and human contact in the metropolis make women more surrounded by bacteria; second, the sebaceous glands of women’s pubic area secrete a lot, and the layers of underwear are not easy to breathe, plus in the hot summer heat, wearing tight pants, pantyhose and other chemical fiber clothing, so that the vulva is often outside in a humid state; third, the urethral opening, vaginal opening and anus, and the vaginal opening and the anus are not easy to breathe. The urethral opening, vaginal opening and anus are close to each other, so you can’t avoid residual urine and vaginal secretions pollution; fourth, vulvar skin folds are very easy to accumulate dirt. Some women often use unqualified pads and don’t change them often, which is conducive to the breeding of bacteria and can easily be brought into the vagina and urethra through sexual intercourse, causing inflammatory infections and endangering health. The leucorrhea produced in normal women’s vagina is an acidic secretion that makes the vagina acidic and has a self-cleaning function, which inhibits the growth and reproduction of pathogenic bacteria and protects the vagina and the adjacent urethra. The normal balance of vaginal flora is beneficial to the body as it keeps each other in check. The vaginal cleanser currently sold in the market has a bactericidal effect, but long-term application can kill the beneficial vaginal bacilli and disrupt the balance of various bacteria, which can lead to vaginitis, cervicitis, pelvic inflammatory disease, and even infertility. Wen got trichomoniasis because she traveled a lot and used pads for a long time. It is one of the more common types of vaginitis, caused by Trichomonas vaginalis. The main symptom is increased vaginal discharge and yellowish green foamy leucorrhea, which can be diagnosed by looking for trichomonads in the leucorrhea suspension. The reason is that most of the patients cannot adhere to the regular medication and the treatment is not complete. The common treatment method of oral and vaginal plugs of methotrexate is a course of treatment for 7-10 days. The second negative test of the leucorrhoea will be considered as treatment. Married couples should have their husbands tested and once trichomonas infection is found in men, both men and women should be treated together. During the treatment period, sexual intercourse is prohibited. The patient’s underwear should be washed, soaked in boiling water for twenty minutes, and placed in the sun to disinfect. Wear cotton underwear, use less pads, keep the vulva clean and do not repeatedly douche the vagina and vulva with cleaning solution. Frequent vaginal douching can change the vaginal pH and reproductive environment, increasing the chance of pelvic infection, which can lead to female infertility. The vaginal opening and urethral opening are mucous membranes, which are delicate, and the labia minora are often closed to cover the vaginal opening and the urethral opening in front of it, which has a protective effect. Vaginal douching should also be done under the guidance of a doctor. Xiao Hong is in her third trimester of pregnancy. Before pregnancy, her vulva was itchy and she did not go to the hospital for laboratory tests, but bought her own medicine for external use. The main symptoms are itchy vulva and white bean curd-like changes in the leucorrhoea. A few people scratch the vulva skin and even break the skin and water because of the itch. However, there are a few people who are asymptomatic and only report that the leucorrhea on their underwear falls off like bean dregs and there is some discomfort in the lower body. Diagnosis: The diagnosis can be confirmed by finding the budding spores and pseudobacterial filaments of the bacterium in the leucorrhoea suspension. There are also many female patients who have fungal vaginitis because their underwear is dry during the rainy season or because they wash their underwear in the same basin with their socks due to heavy foot fungus: some women are cleanliness freaks and repeatedly rinse their vagina and vulva, causing dysbiosis in the vagina. Treatment: Internal medication and vaginal plugs should be taken at the same time, and the medication should be stopped only after two or more cycles of treatment and two negative leucorrhoea tests. Prevention measures are the same as for trichomoniasis.
