Pinworms and Your Child What are pinworms?
Pinworms are a type of worm that can get inside your body. They live in your intestines and eat some of the nutrients from your food. Usually this infection is annoying but not dangerous. Pinworm infections are common in families with small children. If your child has pinworms, you may notice your child moving around a lot in bed at night or being unable to sleep because of an itchy bottom. The itching is caused by a female pinworm that comes out of the rectum to lay eggs around the anus (the opening to the rectum). Sometimes tiny worms (shorter than 1/2 inch) may be seen on the child's bottom at night or they may show up in the child's bowel movement. How do people get pinworms? Pinworms are easy to get. Pinworms are usually spread from child to child, and the eggs can be picked up on children's fingers when they are playing. If the eggs are on their hands or toys, and they put their fingers or toys in their mouth, the tiny eggs can enter their bodies. The eggs are very small and can only be seen with a microscope. The eggs stay in the upper part of the intestine until they hatch. After they hatch, the worms move down the length of the intestine, trying to get out to lay eggs. When the children scratch their itchy bottoms, the tiny eggs can get under their fingernails. As the children move around the house, the eggs may be spread, and other family members may become infected. Sometimes adults breathe in the eggs when the bed covers are shaken. Children easily infect each other while they are playing. Pets do not spread pinworms, although they may carry their own kinds of worms.

Pinworms
Enterobius vermicularis, Oxyuris spp. It is estimated that pinworms infect more than 400,000,000 people throughout the world (10% of humans), and in many areas of the world (e.g., North America and Europe) it is the most common nematode parasite of humans. On a world-wide basis, however, Ascaris lumbricoides ranks #1 infecting more than 1,000,000,000 people (25% of humans). Adult pinworms live in the large intestines; males and females are about 5 mm and 10 mm long, respectively. After copulation the males die. When the female is ready to lay eggs she crawls out of the anus and deposits the eggs on the perianal skin; a single female can produce more than 10,000 eggs. After laying her eggs, the female also dies. At body temperature the eggs develop quickly and are infective (contain 3rd stage juvenile worms) in about six hours. When ingested by another person the eggs hatch in the small intestine, and the juvenile worms grow into adult, sexually mature worms in about a month ( view diagram of the life cycle Pinworms infections can be asymptomatic or result in mild gastrointestinal upsets. A common symptom associated with pinworm infections is perianal itching. Scratching of the perianal skin to relieve the itching can lead to bacterial infections that result in more itching, etc. This cycle can result in a situation where the infected person becomes very uncomfortable. Children infected with pinworms often undergo behavioral changes, including restlessness, irritability, and insomnia. In women, the adult pinworms can enter the vagina and cause additional irritation.

pinworms
Pinworms ( Enterobius vermicularis , for all you taxonomists) are a common parasite of humans. I've read that perhaps 40 or 50% of us harbor at least a few pinworms at any given time. They are tiny white threadlike creatures, about a quarter of an inch long. They live in the colon of humans only. They are harmless and cause no symptoms except itching around the anus. Repeat: no belly aches from pinworms, no weight loss, nothing but itch (admittedly, it can be quite an itch). It's icky to think of, but let's face it: pinworms are a manifestation of our generally poor hygeine when it comes to the toilet. A brief review of the life cycle of the pinworm explains why. The little creature crawls out of the anus and lays eggs. The eggs cause itching. Itching gets scratched. The fingernails have eggs on them. Things get touched with contaminated fingers. Fingers go directly in the mouth (reinfection) or new fingers pick up eggs by touching contaminated objects. Then THOSE fingers go in the mouth. Then the eggs hatch in the GI tract of a new person and off we go. The symptoms are squirming and scratching of the area around the anus, especially at night when the little buggers come out. If you want to check the child suspected of pinworms, go in about a half hour after bedtime and examine the area around the anus for the little white threads. Alternatively, your doctor may want you to do a Scotch-tape slide test before treating.

Pinworms
Within the Order Ascaridida, in the superfamily Oxyyuroidea is a nematode parasite commonly associated with children in daycare centers, boarding schools and also in senior citizens homes. Commonly known as the pinworm Enterobius vermicularis is a nematode which is not highly pathogenic but can be considerably irritating to those infected. The eggs which are very resistant to desiccation are ingested orally and contain infective L3 larvae. They hatch on entering the duodenum and migrate gradually down to the ileo-cecal junction molting twice to become adult worms. This can take anywhere from 15 to 45 days. Males die soon after copulation, but females migrate down the colon through the rectum and out onto the perianal area where they lay their eggs. The gravid females can lay up to 16,000 eggs before they die. The eggs are already partially embryonated and at body temperature reach the L3 stage within 6 hours. The adult worms are very distinctive having a very short stout body with a pointed tail and a very prominent pharyngeal basal bulb. They also have the 3 lips, characteristic of this Order. The eggs also have a very characteristic flattened appearance similar in shape to a grain of rice. An infection with these worms are generally asymptomatic. However, the worms which tend to lay their eggs at night when the host is at rest, can cause irritation when they appear on the perianal area promoting scratching by the host. This scratching can sometimes be aggressive enough to cause bleeding and secondary bacterial infections.

There may be variations in treatment that your pediatrician may recommend based on individual facts and circumstances. Pinworms are the most common type of intestinal infection in children in America. The adult worm measures about ¼ of an inch in length. You can barely see it without a magnifying glass. Pinworms cause no symptoms in the majority of children they infest. You cannot get an infection from pets only from another infected child or adult. Symptoms caused by pinworms are usually confined to the areas surrounding the rectum, although in girls the worms can cause symptoms in the vagina. There may be itching and pain or restlessness at night. Many children grind their teeth.
You may be able to see the worms migrating at night near the rectum. Take a flashlight at night while your child is sleeping.

A mother and her 4 year old boy visit their family doctor for consultation about tiny white worms that the mother has observed on her son's stool. The kid was treated for "worms". After three weeks the mother revisits the doctor with the same story. In this case, however, both the mother and her son appear to be infested with the worm. Moreover she claims "to feel" the worms almost constantly and demands to be set free from this unpleasant experience. Both are treated by the doctor with the same anthelmintic. The doctor advises to have the dogs/cats dewormed by the veterinarian in order to prevent further spread of the infection in the family.

The pinworm is a tiny parasitic worm that lives in the large intestines and comes out at night to lay its eggs around the anus. Pinworms are sometimes called thread worms or seat worms.
Health officials think that as many as forty-two million Americans have pinworms and that most of those infected are children. An estimated one out of every five children between the ages of five and fourteen is infected with pinworms at all times in this country.
Pinworm infections commonly develop in areas where the weather is warm, even when there is good sanitation. However, crowded living conditions do promote the spread of pinworms from one family member to another. Outbreaks may happen at schools or in day cares.
Once pinworms are in the large intestines, they multiply in three ways:

Pinworm Infection
What is pinworm infection?
This infection is caused by a small, white intestinal worm called Enterobius vermicularis (EN-ter-O-be-us ver-MIK-u-lar-is). Pinworms are about the length of a staple and live in the rectum of humans. While an infected person sleeps, female pinworms leave the intestines through the anus and deposit eggs on the surrounding skin.
What are the symptoms of a pinworm infection?
Itching around the anus, disturbed sleep, and irritability are common symptoms. If the infection is heavy, symptoms may also include loss of appetite, restlessness, and difficulty sleeping. Symptoms are caused by the female pinworm laying her eggs. Most symptoms of pinworm infection are mild; many infected people have no symptoms.
Who is at risk for pinworm infection?
Pinworm is the most common worm infection in the United States. School-age children, followed by preschoolers, have the highest rates of infection. In some groups nearly 50% of children are infected. Infection often occurs in more than one family member. Adults are less likely to have pinworm infection, except mothers of infected children. Child care centers, and other institutional settings often have cases of pinworm infection.

I have 3 children. In the last 2 years the same child has been infected with pinworms 3 times. We belong to a family medicine group. The first doctor elected to treat the whole family, but the 2nd and 3rd time I had to request this from different doctors. My question is, does the medicine to treat this infection hurt the family members who are not suffering from this gross infestation? Also, could the worms or eggs live dormant in my daughter or could she be a carrier? Or is there such a thing as a carrier?

Definition A pinworm is a white, very thin worm about 1/4 inch long that moves. If it doesn't wiggle it's probably lint or a thread. Pinworms usually are seen in the anal and buttock area, especially at night or early in the morning. Occasionally one is found on the surface of a bowel movement. More than 10% of children have them. They do not cause any serious health problems, but they can cause considerable itching and irritation of the anal area and buttocks.
Home Treatment When Pinworm is Seen Anti-pinworm Medicine. If you have definitely seen a pinworm, your child needs to be treated. The pinworm medicine is called given times a day. Treatment of Other Family Members for Pinworm. Children are usually infected by children outside the family. If anyone else in your family has anal symptoms or anyone sleeps with your child, call our office during office hours for instructions. Physicians do not agree on whether to treat everyone in the family or only those with symptoms. If any of your child's friends have similar symptoms, be sure to tell their parents to get them tested. Dogs and cats do not carry pinworms.
Suspicious Symptoms But Pinworm Not Seen If your child has itching or irritation of the anal area, she could have pinworms. Keep in mind that many children get itching in this area just from washing their anal area too frequently or vigorously with soap.

What are pinworms?
The pinworm, or Enterobius vermicularis , is one of the most common parasitic infections of humans. Somewhere between 10% and 40% of children have pinworms at any given time ( Pediatric Consult , Williams and Wilkins 1997). The infections are usually limited to children below the age of twelve
The adult pinworms are white and measure less than one half inch long, with the diameter of a strand of thread. These tiny roundworms are quite complex. Like us, they have mouths, throats, and gastrointestinal tracts. Like us they have nervous systems. The females have a vagina, a uterus, and ovaries. The males have a testical, vas deferens, seminal vesicle, and ejaculatory duct. They eat, drink, pee, poop, and reproduce sexually.

Pinworms
Pinworms are tiny parasitic worms that live in the large intestine. The female worms lay their eggs around the anus at night. Symptoms include anal itching, sleeplessness, irritability, and anal irritation due to scratching. Pinworms may also be present without symptoms. Pinworms are common in school-aged children. Pinworms are spread when an uninfected person touches the anal area of an infected person (e.g., during diaper changing) or sheets or other articles contaminated with pinworm eggs, then touches the mouth, transferring the eggs, and swallows the eggs. An infected person can spread pinworms by scratching the anal area, then contaminating food or other objects which are then eaten or touched by uninfected persons. Pinworms can be spread as long as either worms or eggs are present. Eggs can survive up to 2 weeks away from a human host.

A small white, thin worm about 1/4 inch in length that infects the intestinal tract. The main symptom is usually rectal itching, especially intense at night.
  • They may seen with the naked eye and are best seen at night or early in the morning in the rectal area. To diagnose pinworms look with a flashlight in the rectal area a few hours after your child goes to bed or in the early morning. You should see the 1/4 inch threadlike worms moving. Occasionally they are seen with the bowel movement. They come out at night to lay eggs in the rectal area. They are extremely common in childhood and are usually contacted from other children. They become infected when they ingest the pinworm eggs. The swallowed egg matures to the adult pinworm after 3 to 4 weeks. This infection does not reflect uncleanliness or poor hygiene and frequently does recur. They are harmless and do not typically cause abdominal pain or diarrhea. Occasionally, if the child is heavily infected, abdominal pain may be a problem. A laboratory microscopic exam may be done if the diagnosis is uncertain. Discuss with your physician how to order this.

6.09 Enterobiasis (Pinworm or Threadworm)
Presentation
The patient complains of perianal itching which is worse at night, and may contribute to insomnia or superinfection of the excoriated perianal skin. Often, an entire family is affected.
What to do:
  • Examine the anus to rule out other causes of itching, such as rectal prolapse, fecal leakage, hemorrhoids, lice (pediculosis), fungal infections (tinea or candidiasis), or bacterial infections (erythrasma).
  • Look for pinworms directly (especially if the patient comes in at night), and by pressing the sticky side of cellophane tape wrapped around a tongue blade to the perianal skin. Examine the tape under the low power of the microscope for female worms, approximately 1 cm long, 5mm in diameter, with pointed tails. (Use shiny rather than "invisible" tape, because the latter's rough surface makes microscopy difficult .)
  • If you see pinworms or still suspect them, administer a single oral dose of pyrantel pamoate 11mg/kg (maximum l gram) to all family members (Antiminth oral suspension, lml per l0lb). Alternate drugs include mebendazole (Vermox) 100mg in a single po dose (not for infants and pregnant women) and pyrvinium pamoate.
  • Explain to all concerned that this is not a dangerous infection, and that it should be eradicated from the whole family after one treatment (which may be repeated in two or more weeks if there are recurrences).
