Pinworms are also called “threadworms.” They're the most common type of intestinal worm infection in the U.S., and one of the most common in the world. They're thin and white, and about one-quarter to one-half inch long -- about as long as a staple. Tapeworms are flatworms that look a bit like ribbons.
Dipylidium caninum mimicking recurrent enterobius vermicularis (pinworm) infection.
Pinworm eggs can be collected and examined using the “tape test” as soon as the person wakes up. This “test” is done by firmly pressing the adhesive side of clear, transparent cellophane tape to the skin around the anus. The eggs stick to the tape and the tape can be placed on a slide and looked at under a microscope.
At night, the female adult worms deposit their eggs outside the rectum or anal area. 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.
If you have pinworms, you might see the worms in the toilet after you go to the bathroom. They look like tiny pieces of white thread. You also might see them on your underwear when you wake up in the morning. But the pinworm eggs are too tiny to be seen without a microscope.
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.
It moves. If it doesn't wiggle, it's probably lint or a thread. The worm may be seen around the anus or on the child's bottom. It is especially active at night or early morning.
Symptoms of pinworm infection may include: Itching of the anal or vaginal area. Insomnia, irritability, teeth grinding and restlessness. Occasional stomach pain and nausea.
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.
Most people don't experience serious complications from pinworm infections, but in rare cases the following complications can occur: Urinary tract infections (UTIs). UTIs can develop if you do not treat the pinworm infection. Vaginitis and endometritis.
How long after exposure do symptoms begin? Two to six weeks.
Your child may be fussy and wake often at night. If your child is infected, it may take 2 to 8 weeks for symptoms to start.
Pinworms can usually be treated completely with two doses of over-the-counter medicine called pyrantel pamoate, available in the United States under the brand names Pin-X and Reese's Pinworm Medicine. Take one dose immediately and another dose two weeks later.
Pinworm eggs can cling to surfaces, including toys, faucets, bedding and toilet seats, for two weeks. So besides regular cleaning of surfaces, methods to help prevent the spread of pinworm eggs or to prevent reinfection include: Wash in the morning.
Since pinworm eggs and worms are often sparse in stool, examining stool samples is not recommended. Serologic tests are not available for diagnosing pinworm infections.
Rope worms are long, rope-like structures that sometimes occur in the intestines. According to some scientists, they are parasitic worms, but it is more likely that they are nothing more than a buildup of intestinal mucus and other debris.
Symptoms and Causes
Symptoms of a pinworm infection (enterobiasis) include: Anal itching, especially at night: Pinworms lay their eggs around the anus at night, causing itching and irritation. While symptoms are usually mild, anal itching can be severe.
The medications used for the treatment of pinworm are either mebendazole, pyrantel pamoate, or albendazole. Any of these drugs are given in one dose initially, and then another single dose of the same drug two weeks later. Pyrantel pamoate is available without prescription.
Pinworms do not cause abdominal pain, bloody bowel movements,fevers, or poor appetite. If the person has any of these signs or symptoms, they may have a more serious condition and should call a doctor or visit the hospital's emergency department.
Adults are rarely affected, except for parents of infected children. Infection often occurs in more than one family member. While an infected person sleeps, female pinworms crawl out of the anus and lay their eggs on the surrounding skin.
Pinworm, or Enterobius vermicularis, is a small intestinal roundworm about the size of a staple. The female adult worms leave the anus in the middle of the night while the person is sleeping to deposit her eggs around the skin of the perianal region.
Causes of an itchy bottom
infection and infestation – such as staphylococcal bacterial infections and scabies. a skin condition – such as atopic eczema or psoriasis. haemorrhoids (piles) – swellings that contain enlarged and swollen blood vessels in and around the anus.
A person is infected with pinworms by ingesting pinworm eggs either directly or indirectly. These eggs are deposited around the anus by the worm and can be carried to common surfaces such as hands, toys, bedding, clothing, and toilet seats.
Complete die-off within the tested exposure time range was noted for 70 °C, 75 °C and 80 °C, however treatment at 60 °C and 65 °C allowed for development of a few eggs after incubation.
