The test involves pressing the adhesive side of a piece of transparent tape to the skin around the anus of the person you suspect has pinworms as soon as the person awakens. The eggs stick to the tape. You then take the tape to your appointment so the doctor can look for pinworms or eggs under a microscope.
The eggs may be easily seen under a microscope. To obtain a sample, a piece of cellophane tape is pressed against the patient's anal opening. The sticky side of the tape picks up the pinworm eggs and the tape is then stuck to a microscope slide. The eggs can be viewed under the microscope, as seen above.
How is pinworm infection diagnosed? Itching during the night in a child's perianal area strongly suggests pinworm infection. 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.
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.
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.
At night, the adult worms can sometimes be seen directly around the anal area or in pajamas. The worm (one-quarter to one-half inch long) is clearly visible to the naked eye. Finding a worm confirms the diagnosis. If adult worms are not visible, conduct a tape test in the morning.
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.
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.
Symptoms of pinworm
feeling mildly unwell. inflammation of the vagina. adult worms can sometimes be seen in the faeces, and eggs may be seen clinging to the skin around the anus. irritability and behavioural changes.
It's important to note that some tapeworm infections don't require treatment. Sometimes, the tapeworm leaves the body on its own. This is why some people never have symptoms or only have mild symptoms. If a tapeworm doesn't leave your body, your doctor will recommend a treatment based on the type of infection.
The first option is to look for the worms in the perianal reqion 2 to 3 hours after the infected person is asleep. The second option is to touch the perianal skin with transparent tape to collect possible pinworm eggs around the anus first thing in the morning.
Diagnosis of Taenia tapeworm infections is made by examination of stool samples; individuals should also be asked if they have passed tapeworm segments. Stool specimens should be collected on three different days and examined in the lab for Taenia eggs using a microscope.
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.
If left untreated, the intense itching and scratching associated with these infections will result in secondary bacterial infections. Some of these may be difficult to treat. Untreated people can continue to infect other people.
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.
In order to stop the spread of pinworm and possible re-infection, people who are infected should shower every morning to help remove a large amount of the eggs on the skin. Showering is a better method than taking a bath, because showering avoids potentially contaminating the bath water with pinworm eggs.
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.
How long after exposure do symptoms begin? Two to six weeks.
So many of us or our family members have experienced this relatively mild though distressing infection.
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.
People are most likely to get pinworms if they swallow their eggs. This can happen if a person with pinworms scratches around the anus. Then the person gets eggs on his or her hands or under the fingernails. You can then get pinworms if you touch that person or if you touch something he or she touched.
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.
Pinworm infections are more common within families with school-aged children, in primary caregivers of infected children, and in institutionalized children.
If they are well and eating / drinking / urinating / deafecating / breathing normally, then you don't need to present as an emergency.
Don't Worry, They're Rare
If the thought of tapeworms makes you squirm, take heart. You probably won't ever get one. Less than 1,000 people in the U.S. get them a year.
