The occurrence of pinworms may cause the patient to pass some live worms during bowel movements, but they are difficult to see with the naked eye. Pinworms are a parasitic disease that is more common in clinical practice, indicating that pinworms are parasitized in the human intestines and can cause the patient to experience anal itching or vulvar itching. Since pinworms are parasitized in the intestinal tract, it cannot be ruled out that when a person with pinworm disease defecates, there are live worms that will be expelled along with the feces, but it is usually difficult to see them with the naked eye. In general, if you experience unusual perianal itching and sleep disturbance at night, you need to consider pinworms, but you must find the eggs or adult worms to confirm the diagnosis. The diagnosis of pinworms can be confirmed if eggs are found by microscopic examination by scraping, sticking or rubbing contaminants from the perianal wall. The diagnosis can also be confirmed if adult worms are found by shining a light into the perianal skin folds after falling asleep again. Once an individual is diagnosed with pinworms, he or she should actively cooperate with the doctor in deworming treatment, and commonly used deworming medications include mebendazole and enbovirium.
