Infantile vulvitis

　　1. Within 15 days after birth, the vaginal mucus of newborns shows a significant acidic reaction, with a pH of about 5.5. After that, the pH value rises and becomes neutral or alkaline. At birth, the vagina of a female infant remains in a sterile state. In the days before and after delivery, due to the influence of high estrogen from the mother, the vaginal epithelium is similar to the adult level, rich in glycogen, and the vaginal pH is between 4.2 and 4.5. By the third day, the cell population is entirely composed of vaginal bacteria. Around the 15th day, vaginal bacteria maintain a low hormone level until puberty.

　　2. Infants and young children wearing open crotch pants are prone to contamination if not hygienic. If the baby's diaper is not changed in time, the stimulation of stool and urine can cause skin infection. A decrease in the amount of acute infectious diseases, reduced overall resistance, local uncleanliness, and easy infection. A few cases of vulvitis in young children are caused by the presence of vaginal foreign bodies. Improper wiping of the anus with stool can lead to fecal contamination of the vulva. Over-washing the vulva with soap water or other cleaning agents, wearing too tight underwear, or wearing nylon or artificial fiber underwear can all lead to the onset of the disease. The pathogenic bacteria are mostly pyogenic bacteria, such as staphylococcus, streptococcus, and Escherichia coli.

　　Some children may scratch the local area due to pain and itching, resulting in local scratches and bleeding. Some children may experience urinary pain, frequency, and burning sensation. Local skin erosion may form an infection, and even purulent secretions may be discharged. Due to the weak resistance of infants and young children, it is easy for skin and mucosal infections to enter the blood circulation and cause septicemia. At this time, the child may have symptoms such as high fever, poor spirit, not eating, and not crying, which can be confirmed by blood culture examination.

　　1. Vulvar pain, itching, and increased secretion.

　　2. The vulva, clitoris, urethral orifice, and vaginal orifice mucosa are congested, swollen, and have purulent secretions. The underwear often has purulent crusts or thin water-like traces. The vulva is red, swollen, and even peeled. There are local scratches and bleeding, and the labia minora are adhered, the urinary stream becomes finer, and examination can find that the adhered area of the labia minora is thin and translucent.

　　3. Older children can describe vulvar pain, itching, and increased secretion. Infants and young children often cry and are restless due to local pain.

　　4. The vulva, clitoris, urethral orifice, and vaginal orifice mucosa are congested, swollen, and have purulent secretions. When parents pay attention, they may find that the infantile underwear often has purulent crusts or traces of thin water. The vulva is red, swollen, and even peeled. Some children may scratch the local area due to pain and itching, resulting in local scratches and bleeding. Some children may experience urinary pain, frequency, and burning sensation, but they may be overlooked by parents during the acute stage, or the symptoms may be very mild, leading to adhesion of the labia minora after the acute stage, narrowing of the urinary stream, and only discovered later, mistakenly believed to be a congenital malformation of the reproductive organs and seeking medical attention. Examination may find that the adhesion of the labia minora is thin and translucent.

　　Parents and caregivers should pay attention to the cleanliness of the infantile vulva and carry out relevant publicity. The infantile pants should have a tight crotch, and children should be taught to wipe the anus from front to back after each bowel movement to avoid fecal contamination of the vulva. The underwear should be made of cotton fabric and should be loose. If there are infected individuals with the reproductive system in the family or kindergarten, attention should be paid to the isolation of utensils. When infants and young children are suffering from acute infectious diseases, attention should be paid to vulvar hygiene.

      Physical Examination: During the examination, it was found that both sides of the labia minora were adhered, leaving a small hole for urine above or below, and the urinary orifice and vaginal orifice were both covered from this place. A careful examination can find that the adhered area of the labia minora is thinner and more transparent.

　　First, Diet

　　Dietary Taboos:

　　Second, Foods to Eat More of:

　　1. Foods rich in protein and carbohydrates. For example: milk, soy milk, eggs, meats, etc.

　　2. Drink plenty of water, eat more fresh fruits and vegetables. Such as kiwi, apple, pear, green vegetables, banana, strawberry, rapeseed, cabbage, mushrooms, seaweed, kelp, etc.

　　Third, Taboo Foods

　　1. Spicy and刺激性 foods: such as onions, pepper, Sichuan pepper, chili, mustard greens, fennel, etc.

　　2. Fried and greasy foods: such as butter, fried dough sticks, butter, chocolate, etc.

　　It has the effect of increasing dampness and heat, which will increase the secretion of leukorrhea.

　　3. Triggers: such as fish, pork head meat, shrimp, crab, goose meat, chicken wings, chicken head, chicken feet, etc.

　　It will worsen the itching and inflammation of the vulva.

　　Firstly, special infections should be excluded, and the secretion should be sent for examination to check for trichomonads and molds. Cultures can be performed when necessary to identify the pathogenic bacteria and administer appropriate antibiotics. Local treatment includes sitting in a bath of potassium permanganate at a concentration of 1:5000. Apply calamine oil, coptis extract ointment, and cortisone antibiotic ointment to the vulva. Maintain cleanliness and dryness of the vulva. For stubborn cases, add ethinyl estradiol locally to the calamine oil or the aforementioned ointments. For those with adhesions, after disinfection, use fingers to separate downward and outward, which is usually successful. For more firm adhesions, use a curved mosquito forceps to insert into the small hole and then pull it vertically backward to separate the transparent area. After separation, apply calamine oil or disinfected vanaspruce balsam ointment to prevent re-adhesion. Sit in a potassium permanganate bath 1-2 times a day and apply calamine oil until the epidermis is normal.
