Vaginal beautiful roundworm disease

　　1. Etiology

　　The beautiful vaginal nematode disease is caused by the shared use of the same pond water by humans and animals. There have been reports by some scholars of a rural woman living in an area with a lack of water resources, poor hygiene conditions, and the habit of taking a bath in a basin who was infected with the beautiful vaginal nematode disease.

　　2. Pathogenesis

　　The adult worms are parasitic in the vaginal mucosa of humans, and the migration of the worms can cause damage to the vaginal mucosa, leading to the formation of vesicles, blood blisters, and ulcers. The vaginal mucosa can be seen with small white vesicles and milky white linear curved elevations.

　　Concurrent infection with other pathogens in the vulva and vagina, such as vaginitis. Normal healthy women have a natural defense function against pathogens due to the anatomical and physiological characteristics of the vagina. For example, the closure of the vaginal orifice, the close adhesion of the anterior and posterior vaginal walls, the proliferation of vaginal epithelial cells under the influence of estrogen, and the keratinization of the epidermal cells, the vaginal pH is maintained at 4-5, which inhibits the proliferation of pathogenic organisms that adapt to alkalinity, such as anaerobic bacteria. When the natural defense function of the vagina is destroyed, pathogens are more likely to invade and cause vaginal inflammation.

　　The main clinical symptoms of the beautiful vaginal nematode disease are increased leukorrhea, itching of the vulva and vagina, a sensation of something piercing, and some patients may have mental and neurological symptoms: mental unrest, fear, allergy, insomnia, headache, anorexia, and so on. All these manifestations will be alleviated and disappear as soon as the worm is removed.

　　Manage polluted water bodies, pay attention to water hygiene. The care solution is generally not necessary, but it can be used, but not frequently, to maintain once a week or every two weeks. Because the vagina itself has a self-cleaning function, which is due to the rich glycogen in the vaginal epithelial cells. This glycogen is generated by the decomposition of lactobacilli that寄生 in the vagina, producing lactic acid. Lactic acid creates an acidic environment inside the vagina, which can prevent the proliferation of many pathogenic bacteria. The killing components in the care solution are large, which can kill both harmful and beneficial bacteria. It is even more not recommended to use it during menstruation, because during menstruation, the vaginal excretion is large, and using the care solution to wash can slow down the work of beneficial bacteria.

　　The beautiful vaginal nematode disease should be examined as follows: vaginal mucosal vesicle smears for microscopic examination, ulcer surface tissue pathological examination, increased eosinophils in the blood, sometimes up to 20%. According to the patient's dietary hygiene habits, local and systemic clinical manifestations, and the identification of the worm through local examination of the vagina, the diagnosis can be clearly made.

　　Prevention of阴道美丽筒线虫 disease should start from the following aspects:

　　1. Pay attention to dietary hygiene, do not eat unclean raw and cold foods, and vegetables and fruits that are eaten raw must be washed before they can be eaten.

　　2. Develop good hygiene habits, do not defecate at will. The transmission route of ascariasis is that the eggs excreted by the worm are excreted with feces and then contaminate the surrounding environment, and can also contaminate vegetables and fruits. Once eaten, infection can occur. It is necessary to wash hands before and after meals, and often cut nails. Children should not suck their fingers.

　　3. In the prevention and treatment of阴道美丽筒线虫 disease, it is necessary to carry out health education and cultivate good hygiene habits. The focus of the general survey is on children's collective units (kindergartens, primary schools), to carry out general survey and treatment to ensure children's health. Strengthen fecal management, improve the living environment, and do a good job in fly control and prevention to prevent the spread of eggs. Experiments have shown that eggs die within half an hour at 45-50℃.

　　Building sedimentation fermentation fecal ponds or using composting methods - that is, using the heat produced by fermentation and the ammonia decomposed from feces and urine to kill the eggs in the feces.

　　Firstly, precautions before the treatment of阴道美丽筒线虫病

　　1. Avoid or reduce direct contact with epidemic water. Wear protective gloves and wear long boots and nylon protective pants before going into the water in the epidemic area.

　　2. Aquatic larvicide should be carried out in susceptible areas, and the drinking water hygiene of temporary residential areas of residents should be strengthened.

　　3. Do not eat beetles and bed bugs, do not drink raw water and do not eat unclean vegetables and fruits. If raw or semi-raw insects containing infective larvae are eaten as hosts.

　　Secondly, the Western medical treatment method for阴道美丽筒线虫病

　　1. Treatment

　　(1) The main treatment method is to cut open the blood blister or use a sterilized needle to puncture the mucosa to pull out the worm, and the symptoms will disappear.

　　(2) Metronidazole 400mg can be taken orally, 3 times a day, for 7 consecutive days.

　　(3) After 100ml of 0.5% metronidazole injection is used for vaginal irrigation, 200mg of metronidazole is placed in the vagina, once a day. Continuous treatment for 7 days.

　　2. Prognosis

　　No adverse outcomes occurred after treatment.
