What causes small rashes at the vaginal opening?

Small rashes at the vaginal opening are usually caused by bacterial infection. Pay attention to hygiene, use vaginal wash to clean the skin, apply erythromycin or chlortetracycline, do not eat spicy food, do not drink alcohol, and do not stay up late. If the medication has no effect after two days, it is recommended to go to the hospital's dermatology department for a routine blood test.

Causes of vaginal infection

1. Indirect contact infection

Contact with toilets, bathtubs, bath seats, towels in public toilets that are contaminated with bacteria, and using unclean toilet paper can cause infection.

2. Sexual transmission

It is one of the causes of the disease. At least 10% of men with symptoms on the female side have bacterial urethritis.

3. Taking large amounts of antibiotics

Antibiotics change the vaginal microenvironment, causing pathogenic bacterial pathogens to multiply and leading to localized bacterial vaginosis.

4. Excessive attention to hygiene

In order to maintain hygiene, some women often use medicated washes to irrigate the vagina, which can easily destroy the acid and alkaline environment of the vagina and make it easy to get bacterial vaginitis.

Clinical manifestations

10% to 50% of patients are asymptomatic, while those with symptoms complain of grayish-white leucorrhea with a fishy odor, vaginal burning and itching.

Most patients with this disease are women of childbearing age. The disease has a slow onset and the subjective symptoms are not obvious, with the main manifestation being increased leucorrhea. The examination of vaginal secretions has the following characteristics: ① The pH value reaches 5.0-5.5, which is higher than normal. ② The leucorrhea is gray or gray-green, homogeneous, with a paste-like consistency, and may contain bubbles. ③There is a foul smell like rotten fish. The odor of women becomes worse after menstruation or sexual intercourse, and their sexual partners' genitals may also emit the same odor. ④ Patients with combined Trichomonas or Candida infection may experience vulvar itching, vaginal burning sensation, or pain during sexual intercourse.

This disease can often be combined with other vaginal sexually transmitted diseases, and its clinical manifestations may vary depending on the comorbidities. When combined with gonococcal infection, vaginal discharge will be obviously purulent and urinary tract irritation symptoms such as dysuria and dysuria may occur; when combined with Trichomonas infection, foamy vaginal discharge may appear, and itching may be aggravated and extremely itchy; when combined with Candida infection, vaginal discharge may appear curd-like or tofu-like.

examine

1. Smear microscopy

Clue cells can be found by taking a smear of the secretions. Clue cells are epithelial cells with a large number of Gardnerella attached to the surface. The characteristics are that the surface of the epithelial cells is rough or has fine particles, and the bacteria are Gram-negative coccobacilli.

2. Amine test

Take a drop of 10% potassium hydroxide solution and add it to the vaginal secretions. You can smell a "fishy" ammonia released because the secretions have a high amine content and can release ammonia gas when they come into contact with alkali.

3. Cultivation method

After isolation and then culture, round, opaque, smooth-surface colonies with a diameter of 0.5 mm can be seen.

4. Biochemical method

Vaginal secretions were taken for biochemical analysis. Normal women had high lactate levels and low succinate levels, while women with this disease had the opposite values.

5. Fluorescent antibody method

The smear was stained with fluorescent antibody and examined under a microscope.
