Pinworm infections often produce no symptoms but, when they occur, symptoms can include: itchy bottom, especially at night. reduced appetite. feeling mildly unwell.
Diagnosis is made by identifying the worm or its eggs. Worms can sometimes be seen on the skin near the anus or on underclothing, pajamas, or sheets about 2 to 3 hours after falling asleep. Pinworm eggs can be collected and examined using the “tape test” as soon as the person wakes up.
Pinworms can rarely migrate into the vagina or urinary tract causing irritation in these regions. Intense itching is again the prominent complaint. This location of infection is less common than the perianal region, and the infection usually goes away on its own.
Although not all infected people will have symptoms, many will experience itching around the rectum. Some females may also experience itching in the genital area. How soon do symptoms appear? Symptoms usually are noticed one to two months after infection.
Pinworms (Enterobius vermicularis) are small, white worms about the length of a staple that live in the rectum of humans. About 20% of children will get pinworms. It is more common in school-age children than pre- schoolers. Adults are rarely affected, except for parents of infected children.
The best way to diagnose this infection is to do a tape test. The best time to do this is in the morning before bathing, because pinworms lay their eggs at night. Steps for the test are: Firmly press the sticky side of a 1-inch (2.5 centimeters) strip of cellophane tape over the anal area for a few seconds.
One way to detect pinworms is to shine a flashlight on the anal area. The worms are tiny, white, and threadlike. If none are seen, check for 2 or 3 additional nights. The best way to diagnose this infection is to do a tape test.
Sometimes crusty areas develop, which may be mistaken for dandruff. If left untreated, the area can become boggy (spongy), discharge pus and develop areas of hair loss. This form of ringworm is most common in children.
Strict hygiene measures can clear up pinworm infection without medication, and reduce the risk of reinfection. The worm has a lifespan of about six weeks, therefore the strict hygiene needs to last that long.
It is especially active at night or early morning. Rarely, the pinworm is seen on the surface of a stool. The pinworm's secretions are a strong skin irritant and cause the itching.
Complications. Typical pinworm infections don't cause serious problems. In rare circumstances, heavy infestations can cause infection of female genitals. The parasite can travel from the anal area up the vagina to the uterus, fallopian tubes and around the pelvic organs.
The eggs pass into the digestive system, where they hatch. About 1 to 2 months later, adult female pinworms lay eggs on the skin right around the anus, which makes the area itchy. Often, this happens at night.
Pinworm infections are very common, affecting approximately 1 billion people worldwide. People of all ages can become infected with pinworms, but the infections are found most often in children. Caregivers and family members of infected children have a higher risk of infection.
If you are self-treating for pinworms, take the medication once only. Do not repeat the dose without talking with your doctor first. Depending on the type of worm infection you have, your doctor may direct you to take the medication only once or for several days.
Pinworm Infection Symptoms
Anal itching, especially at night. Restless sleep. Itching in the vaginal area -- if adult worms move to your vagina. Feeling irritable.
To treat pinworm infection, your doctor may recommend over-the-counter pyrantel pamoate or prescribe medication to all members of your household to prevent infection and reinfection. The most common prescription anti-parasite medications for pinworms are: Mebendazole. Albendazole (Albenza)
Chlorine dioxide gas inactivates pinworm eggs in a non-invasive and non-corrosive manner.
Pinworm eggs continue to be present (excreted) in the feces of an infected person for up to a week after the treatment, so precautions should be taken to prevent reinfection by washing hands thoroughly, especially under the nails. Bathe daily. Change and wash clothing and bedding frequently.
Most pinworm infections are mild and easily treated. Your doctor may prescribe a single chewable tablet of a medicine called mebendazole. A second tablet is taken about 3 weeks later if the infection isn't cured. Or your doctor may recommend another kind of medicine called pyrantel, which is taken as a single dose.
Pinworms are small white worms about 1/2 inch long and as thin as a thread. They can sometimes be seen in and around the child's bottom (anus) and in bowel movements.
How long does pinworms last? The life cycle of a pinworm is 4 to 6 weeks. Without treatment, infestation will continue as long as fresh eggs are being swallowed, unless a person develops immunity to pinworms, which is unusual before age 15.
As eggs can become infective after 3-5 days the bathing should be repeated every third day. If a problem is occurring, then daily bathing is best. If the skin is irritated a dilute mild antiseptic can help. Applying Vaseline to the skin after cleaning can help protect the skin and prevent the eggs sticking.
Pinworm infections often produce no symptoms but, when they occur, symptoms can include: itchy bottom, especially at night. reduced appetite. feeling mildly unwell.
Causes of itchy bottom
a bacterial infection – such as those that cause streptococcal infections. a skin condition – such as atopic eczema, where the skin becomes red, dry and flaky. haemorrhoids (piles) – swellings that contain enlarged and swollen blood vessels in and around the anus.
