Does your little one's scalp itch all the time? Or does it get red, scaly, and look like it's losing hair? Does he sometimes get a little feverish and have lice around his neck? If so, that's what we're going to talk about. In medical terms, we call this condition Tinea Capitis . Some people also call it "ringworm of the head." Simply put, it's a fungal infection. Let's talk about this in a little more detail, because it's very important to recognize and treat it properly.
What is Tinea Capitis?
Simply put, tinea capitis is a fungal infection that affects the skin and hair on your child's head. Some people also call it "Scalp Ringworm," but it has nothing to do with worms. It happens when a type of fungus gets into your child's hair follicles. Sometimes, the fungus can even get into the hair shaft. Not only that, but it can also affect the eyelashes and eyebrows of some children.
There are two main types of tinea capitis. One is the inflammatory type . This can sometimes lead to a condition called a kerion . A kerion is a painful, pus-filled, sometimes watery lesion. This is caused by the child's immune system reacting to the fungus. This can cause scarring and even permanent hair loss.
The other type is the non-inflammatory type . This usually does not cause permanent hair loss. However, it can cause something called "black dot tinea capitis." This means that your child's hair follicles break off at the skin level of the scalp. This looks like a black dot. "Gray patch tinea capitis" is also a non-inflammatory type. This is where the hair follicles break off just above the skin, leaving short, scaly patches.
Who is most likely to get this?
Tinea Capitis is most common in children between the ages of 3 and 14. However, it can also affect adults. People with weakened immune systems (such as those with certain illnesses or those taking certain medications) are at higher risk.
How common is this condition?
In fact, Tinea Capitis is a common condition seen by pediatricians and dermatologists. This infection can be seen in any country in the world. However, it is seen more frequently in regions with hot, humid climates (like Sri Lanka!) . It is very common in countries like Central America, Southeast Asia, and Africa.
What are the symptoms of this?
Tinea Capitis can affect all or part of your child's scalp. Symptoms may include:
- Swollen, red spots or patches.
- Dry, scaly rash.
- It's very itchy .
- Hair loss in places (alopecia) .
- The skin is peeling off like a bald eagle.
- Body heat, slight fever.
- Swollen lymph nodes around the neck.
Now, in the inflammatory condition of Tinea Capitis, painful, swollen patches may appear on the scalp. This is called a Kerion . These Kerions may sometimes crust over and ooze a pus-like fluid. Severe cases of Tinea Capitis can cause scarring and hair loss in those areas. Therefore, it is important to see a doctor as soon as possible if you notice these symptoms.
In "black dot tinea capitis", the hair shaft breaks off at the skin level, giving the appearance of black dots. In "gray patch tinea capitis", short, broken pieces of hair are left behind.
What is the reason for this?
Tinea Capitis is caused by a type of fungus called Dermatophytes . In countries like America, the main causes are the dermatophytes `(Microsporum)` and `(Trichophyton)`. These fungi thrive in warm, moist environments . That is why it is common in countries like ours, which have a slightly hot, sweaty climate.
Also, Tinea Capitis is a very contagious disease . Your child can catch it from an infected person, an animal, or from the soil. It can also be spread by touching objects and surfaces that have been contaminated with the fungus (such as towels, combs, pillowcases). Tinea Capitis can survive on infected objects for a long time.
What are the risk factors that contribute to this development?
Tinea Capitis is a fungus that thrives in moist, warm environments. So, the main risk factors for it are:
- Living in a tropical environment (like Sri Lanka).
- Traveling to areas with hot, humid climates.
- Places where many people live close together (e.g. school dormitories, kindergartens).
- Playing contact sports that involve touching other people.
- There are small wounds on the skin of the head.
- Not bathing the child often, not washing their hair .
- Excessive sweating (hyperhidrosis) .
- Exchanging things like hats, combs, hairpins, and sports equipment (helmets) with each other .
- Weakened immune system. This can be caused by conditions like HIV/AIDS, cancer, or diabetes.
How is this transmitted?
Tinea Capitis is a highly contagious disease , especially among children. It can be transmitted in three main ways.
1. People to people
Your child can get it if they come into direct contact with someone who has the infection. That person may or may not have symptoms. But if they are a carrier, they can spread the infection to others.
2. From animals
Your child can get it if they touch an infected animal. It can be spread from many different animals, including pets like dogs and cats. So it's important to wash your hands thoroughly after playing with animals.
3. Fomites - Infected objects
Fomites are objects or materials that can carry an infection. Sharing items such as clothing, hats, combs, hairbrushes, and helmets can spread tinea capitis to your child.
How does a doctor recognize this?
Your child's doctor will ask you about his or her symptoms. Then he or she will examine your child. He or she will look closely at your child's hair and scalp. Sometimes you can tell it's ringworm right away.
However, to be sure, the doctor will need to take a small sample from the infected area. He may remove a few hairs or scrape a small amount of scalp skin. The doctor may also decide to do some more tests to see if it is tinea capitis.
What tests are being done to confirm this?
To determine if you have tinea capitis, your doctor may perform the following tests:
1. KOH stain test
In this, the doctor gently scrapes a small amount of skin from the infected area of your child's head. He or she may also remove a few hairs. In the lab, a technician will place the sample on a microscope slide. The slide will have a drop of potassium hydroxide (KOH). When viewed under the microscope, the KOH solution will show if there is fungus. The results are usually available within 24 hours.
2. Culture test
If the KOH stain test doesn't give a clear result, your doctor may order a culture test. A culture is a medium that allows fungi to grow. This will help the technician identify exactly what fungus is causing your child's infection. A culture test is more accurate than a KOH stain, but it can take several weeks for the results to come back.
3. Wood light test
A Wood's light is a special type of ultraviolet (UV) light. The doctor will hold this light to your child's scalp. This may help identify the type of fungus that is causing the ringworm. Some types of fungi glow under this UV light, while others do not. Depending on the type of dermatophyte on the scalp, the area may glow yellow, green, or blue.
How is it treated?
Your child's doctor will prescribe an antifungal medication to treat tinea capitis. Usually, topical treatments alone don't work, so an oral medication is prescribed. Your child will need to take this medication for at least six weeks . The most common oral antifungal medications for children are Griseofulvin and Terbinafine.
However, the doctor may also prescribe a selenium sulfide shampoo . You will need to wash your child's head with this shampoo at least twice a week. This shampoo may help stop the spread of tinea capitis, but it will not cure it completely.
The doctor may also recommend an antifungal cream. This cream should be applied directly to the infected areas of the child's scalp. This cream can also help prevent the infection from spreading. However, this alone cannot completely cure tinea capitis.
Remember, these shampoos and creams only help reduce the spread of the disease. To fully cure the disease, you must use the medicine prescribed by your doctor exactly for the prescribed period.
If your child has the aforementioned kerion ( pus-filled sore), the doctor may prescribe a corticosteroid, such as Prednisone. Steroids can help reduce inflammation and reduce the risk of scarring and permanent hair loss.
Tinea Capitis in adults is treated in a similar manner. An oral antifungal medication should be taken for at least six weeks to ensure that the infection is completely gone. Medications for adults include terbinafine and itraconazole. Your doctor may also recommend selenium sulfide shampoo, antifungal creams, and steroids.
How can you and your family take care of yourself at home?
If you or your child has tinea capitis, you should check to see if everyone else in your household has the infection . Sometimes, even if they don't have symptoms, it's a good idea to treat them too. Otherwise, the infection could be passed back and forth between everyone. Children can use an antifungal cream or shampoo twice a week for at least six weeks.
Also, things like pillows, bed sheets, and towels should be washed and dried thoroughly . Things like combs, brushes, and hairpins that are used should be thoroughly cleaned and disinfected. It may be better to buy new ones.
How can I prevent this from happening again?
There are several things you can do to prevent tinea capitis:
- Do not share items you use (such as hats, combs, pillows, helmets) with others.
- Keep the baby's scalp clean and dry.
- Keep children with tinea capitis away from healthy children (until the infection has cleared up).
- Avoid places where the child may be exposed to the infection (e.g. public swimming pools).
- Wash pillowcases and bed sheets regularly.
- Wash your hands thoroughly after touching or playing with pets.
What can we expect in the future?
Non-inflammatory tinea capitis can be treated quickly and consistently, and can lead to a good recovery . However, tinea capitis can sometimes be difficult to treat. It is therefore important to complete the full course of antifungal medication given to your child. Severe inflammatory tinea capitis can cause scarring and permanent hair loss. This is why we recommend seeing a doctor as soon as possible.
How long will this last?
Fungal infections can be difficult to treat. That's why it's important to use your child's antifungal medication exactly as prescribed. You may need to take the medication for at least six weeks . Even if your child's infection seems to be decreasing or completely gone, it can come back if not treated properly. In most cases, tinea capitis will go away on its own by the time your child reaches adulthood.
What is the difference between Tinea Capitis and Seborrheic Dermatitis?
Seborrheic dermatitis is also a common skin condition. It is more common in older children. Unlike tinea capitis, it does not cause hair loss. In some cases of tinea capitis, the lesions may look like those of seborrheic dermatitis. However, seborrheic dermatitis does not cause hair loss. Seborrheic dermatitis can be treated with over-the-counter medications. Tinea capitis usually requires a prescription from a doctor.
What is the difference between Tinea Capitis and Tinea Barbae?
Tinea Barbae is a fungal infection similar to Tinea Capitis. However, it affects the facial hair and beard. It is not as common as Tinea Capitis and usually affects older men. Tinea Barbae is most common among farmers. It is spread by direct contact with an infected animal. Person-to-person transmission is rare.
Finally, things to remember
Tinea Capitis can be an itchy, uncomfortable infection for your child. However, with prompt and consistent treatment , you can help your child get rid of the infection. However, this can take some time. It is very important to follow your child's doctor's instructions exactly. Your child should complete the full course of treatment. It can take at least six weeks for a fungal infection to clear up. If the infection does not go away, see your doctor again. They are there to help you and your child.
