Genital candidiasis is a common disease of the genitalia in men and women that is caused by a fungal infection called Candida albicans. The disease spreads easily among women and causes symptoms such as increased leucorrhea and itching in the pubic area. Since the disease can be transmitted through sexual intercourse, the World Health Organization has included it among sexually transmitted diseases. Candida albicans is a kind of putrefactive parasitic bacteria, which usually lives in human skin, mucous membrane, digestive tract and other organs. When the resistance of the organism decreases, Candida albicans will multiply and when it reaches a certain amount, the human body will develop the disease, so Candida albicans is a conditionally pathogenic bacteria. In women, when the glycogen of vaginal epithelial cells increases and acidity is enhanced, Candida albicans will multiply and cause vaginitis, so this disease is common in pregnant women, diabetic patients and patients receiving estrogen therapy. In addition, the disease can be sexually transmitted, on the grounds that couples often develop the disease at the same time, which is reason enough to prove that the disease can be sexually transmitted. Of course, Candida albicans can also be transmitted through public baths, bath tubs, bath towels, swimsuits, clothing, medical devices and dressings. The vulva and vaginitis of Candida albicans mainly manifests as vaginal itching and burning sensation, and the symptoms usually range from mild to intolerable. At this time, the vaginal mucosa is red and edematous, with white curd-like or flaky membrane-like material attached, which can be easily peeled off, and there can be erosion or shallow ulcers under it, and the leucorrhoea is a lot, watery or pus-like, in which there are cheese like white lumps of different sizes or bean curd-like material. The male Candida glans penis is mostly infected due to the spouse suffering from Candida vaginitis or infected due to unclean sexual intercourse. The symptoms are itching of the penis, mucus-like or pus-like discharge from the foreskin, redness and swelling of the glans and coronal groove of the penis, vesicular surface, maculopapular rash, and even thin-walled pustules on the surface of the penis head, and in severe cases, it can spread to the penis body, scrotum, inner thighs and groin. The symptoms of male Candida urethritis are not as obvious as those of other urethritis, and there are usually no symptoms of acute urethritis such as frequent urination, urgent urination, painful urination, etc. Instead, they are manifested as itching sensation in the urethra, burning sensation in urination, and little urethral discharge, which is watery or mucus-like. The complication of female genital candidiasis is mainly female candidal vaginitis (mycosis fungoides), because the stimulation of the vulva by the discharge, together with secondary infection, causes candidal vulvovaginitis. At this time, erythema and vesicles appear around the labia majora, labia minora, mons pubis, vulva and inner thighs, with moist white scales on the surface, blood papules and small blisters may appear around the erythema, and there is obvious itching. In addition to the typical symptoms and signs, laboratory tests are essential for the diagnosis of genital candidiasis. Generally, direct microscopic examination of the secretions can make a clear diagnosis, and the culture of Candida albicans can also be used if necessary, which can make a clearer diagnosis. Direct microscopic examination is a very simple laboratory method. Take a small amount of secretion on a glass slide, add a drop of potassium hydroxide or isotonic sodium chloride solution, cover the slide, placed under the microscope, can see the spores and mycelium of Candida albicans. The accuracy of diagnosis by this method is 70%. Genital Candida albicans is often confused with genital trichomoniasis. They share symptoms of genital itching, increased discharge and leucorrhea, but the former genital discharge is cheesy or pea-like, while the latter genital discharge is grayish-yellow with a fishy odor. Direct microscopic tests can help in the differential diagnosis of the two. The majority of genital candidiasis is a conditional pathogenic infection, in addition to the infection caused by unclean sexual intercourse, certain diseases suffered by the individual is also the cause of this disease. Therefore, before treating this disease, one should check whether one has diabetes, immunodeficiency disease, etc., and whether the patient has long-term application of antibiotics, hormones and other drugs. If the patient has such a condition, it should be treated promptly. This is very crucial for the treatment of this disease. Female genital candidiasis is often due to glycogen breakdown and vaginal reproduction of Candida albicans is accelerated in an acidic environment. Therefore, it is helpful to treat the disease by changing the pH of the vagina. A common method is to rinse the vagina and vulva with 2% to 4% soda, gently wipe dry, and then place a mycobacterial suppository in the vagina, which is often effective. For genital candida infection, the commonly used drugs are mycobacterium, fluconazole, itraconazole, etc. (1) Mycoplasma. It can be taken internally and used externally. Internally, each time 500,000 units, 4 times a day. Externally as a suppository, each suppository is 250,000 units. (2) Fluconazole. Also known as Da Fluconazole, it usually takes effect with 1 oral dose of 150mg, but it is noteworthy that it is easy to recur after cure. (3) Itraconazole. Also known as Spironolactone, generally 100mg per dose, twice daily, for 10 days as a course of treatment. Self-protection against genital candidiasis Extreme treatment of primary diseases such as diabetes, timely discontinuation of antibiotics, estrogen, etc. Change underwear regularly, used underwear, towels, etc. should be scalded with boiling water. Local treatment should be given to pregnant women and last until the eighth month of pregnancy. Avoid sexual intercourse during the treatment period, and treat your spouse at the same time if necessary.
