Another School Year… Another Flu Season

It’s hard to believe it’s already that time of year again. Here’s what’s new for flu season 2010-2011:

This years’ flu shot contains the H1N1 (“swine flu”) strain and 2 other strains of flu virus most likely to cause seasonal flu this year. Regardless of whether you received seasonal flu vaccine, H1N1 vaccine, or both vaccines in 2009, vaccination with a 2010-11 seasonal influenza vaccine is necessary. Although the World Health Organization announced the end of the H1N1 pandemic this month, the virus does continue to circulate. The CDC recommends that all people age 6 months and older receive the flu shot — not just people in high risk categories.

Each year, it is estimated that there are 200,00 people hospitalized due to influenza and there are 36,000 deaths related to complications of influenza.

According the Flu Resource Center here is a list of some of the top places cold and flu germs hide:
1. Handshakes, sneezes, kisses
2. Kitchen sink sponges and dishcloths
3. Restrooms and toilet seats
4. Doorknobs
5. Drinking fountains
6. Shopping carts

The best protection against the flu are to WASH YOUR HANDS FREQUENTLY and GET VACCINATED.

Meriter clinics are anticipating having flu vaccine available early September, so remember to check our Web site or to call your primary care physician’s office for availability.

What is Swimmer's Ear?

While on vacation, my son started complaining about his ears hurting when I put on his shirt. At first I just thought it was him being a typical 4 year-old, but it caught my attention when it really seemed to bother him when I bumped his ear while brushing his hair and then later when giving him a hug. Turns out my son had developed swimmer’s ear after having spent several days in the pool.

Swimmer’s ear is a common summer occurrence, but can occur year round even in people who do not swim. It is also called otitis externa because it is inflammation of the external ear canal. The inflammation can be caused by a number of things, but is most commonly caused by water in the ear canal that causes skin breakdown. The loss of skin integrity allows bacteria or fungus to enter the skin and cause inflammation. Other things that can cause skin breakdown and lead to otitis externa are using Q-tips, a foreign body in the ear canal, hearing aid, a rash that extends into the canal or drainage from a perforated ear drum.

Children usually complain of itching or pain in the ear. Children may have drainage from the ear as well. It often hurts when either the tragus (the prominence in front of the external opening of the outer ear) or pinna (the largely cartilaginous projecting portion of the external ear) are moved.

Physicians diagnose otitis externa by looking in the ear with an otoscope and by the tenderness elicited with movement of the ear. It is often treated with prescription ear drops. Oral antibiotics are sometimes used if the infection is severe or spread beyond the ear canal. There are over-the-counter ear drops but these will not treat otitis externa that has already developed. The drops should be put in the ear with the child laying on his or her side and remaining there for 3-5 minutes for the medication to have contact with the skin of the canal. The ear canal should be kept as dry as possible during the healing process. Avoid swimming and bathing that would get the canal wet. A cool air blow-dryer can be used if the ear does become wet.

Once a child has had otitis externa, steps should be taken to prevent it in the future. Ear plugs are an option, but sometimes if they enter the canal, they can also cause irritation. Drying the ears after swimming and bathing is important. First dry with a towel. You can again use a cool air blow-dryer. Another option is a couple drops of 70% rubbing alcohol solution or a mixture of ½ alcohol plus ½ vinegar placed in the canal will help dry up any water in the canal.

Enjoy the warm weather while it lasts!

Rotavirus (or the lack thereof): A vaccine success story

As a hospitalist, I see a sicker patient group. Only when a parent is very worried or a clinic provider feels they need ongoing attention do I see a child in the ED or in the hospital. Now, as we approach the end of summer, I can’t help but feel like something is missing. Five years ago, it was common in the spring and early summer to have children in the hospital for vomiting, diarrhea and dehydration from rotavirus. Rotavirus is a common virus that infects most children under 5 years of age and is most severe for children under 2 years of age. Every year there was a significant number of children who needed to stay in the hospital for IV fluids while they recovered from this virus. So, where did it go?

If your child is less than 4 years old then you may remember an oral vaccine received at the 2, 4 and 6 month visits. In 2006, the FDA approved the vaccine RotaTeq® and shortly thereafter, it was recommended routinely for infants. Since that time there have been other similar vaccines approved as well. This vaccine is not 100% effective in preventing rotavirus, but its goal was to reduce the severity of illness and prevent the need for hospitalization.

Recently, there have been some published studies on the effect this vaccine has had in the United States. One study showed a 46% decrease in need for hospitalization. Another study showed 100% effectiveness in preventing hospitalization compared to children who did not receive the vaccine. Wow! As a younger physician, it has been wonderful to see the impact vaccines can have on the health and well being of our children.

Although I love meeting the children and their families, I am glad more kids are at home. Staying in the hospital is no fun for anyone. To rotavirus, I say good riddance and you won’t be missed.

What Every Parent Should Know About Concussions

As a parent, it is exciting to watch your young athlete from the side-lines, making a great catch or kicking a goal. Also, as a parent, safety is always something that is in the back of our minds. One injury I would like to address is a concussion. It has brought recent media attention due to famous athletes or movie stars sustaining an injury to the head. However, it can affect any athlete.

What is a concussion?
A concussion is any injury to the head that potentially affects the function of the brain. It is usually the result of a blow or jolt to the head. However, it is important to know that it can also be secondary to a blow to any part of the body that causes the brain in the head to move back and forth, as per definition from the CDC. It is important to be aware of this because an athlete can sustain a serious concussion without a blow to the head. For example, imagine a hit to the shoulder, causing your head to move back and forth like whip lash.

A CDC study found that among youth ages 5 to 18 years old, the sports and recreation activities that generated the greatest number of emergency department visits for Traumatic Brain Injury were popular activities such as bicycling, football, basketball, playground activities and soccer.

What are some signs of a concussion?
After a blow to the head, talk to your doctor if you have any of the following signs of concussion:

• Headache
• Vision disturbance
• Dizziness
• Loss of balance
• Confusion
• Memory loss (called amnesia)
• Ringing in the ears
• Difficulty concentrating
• Nausea
• Feeling foggy or groggy
• Sensitivity to light or noise

However, some athletes may just say that they “don’t feel right.” This could be a sign of a concussion as well. Remember, you do not need to have loss of consciousness in order to have a concussion. If an athlete has been suspected to have a concussion, they should be evaluated by a physician. Secondly, due to new rules and regulations, the athlete will not be able to play that day and will need medical clearance by a physician in order to return to play for future games.

Recovery and safe return to play:
It is crucial to allow enough healing and recovery time following a concussion to prevent further damage. Research suggests that the effects of repeated concussion are cumulative over time.

Most athletes who experience an initial concussion can recover completely as long as they do not return to contact sports too soon. Following a concussion, there is a period of change in brain function that may last anywhere from 24 hours to 10 days. During this time, the brain may be vulnerable to more severe or permanent injury. If the athlete sustains a second concussion during this time period, the risk of permanent brain injury increases.

I encourage you to visit the CDC Web site to understand more about concussions.

Meriter Pediatrics now offers ImPACT concussion management baseline testing. Think of it as a pre-season physical for the brain!

The New Rules of Head Lice: Part 2

Continued from yesterday's post ...
What should you do if your child has head lice? First, all other household members should be checked. So should any kids who were likely to have direct head-to-head contact. Anyone with live lice or eggs close to the scalp should be treated. Anyone who shares a bed with the infested person should also be treated.

Hair care items and bedding that have been in contact with the infested person in the 48 hours prior to treatment should be cleaned. (If it’s been longer than 48 hours, any lice will already be dead.) A temperature of 130 degrees or more (by washing or drying) will kill lice and eggs. Furniture, carpeting, and other fabric covered items can be vacuumed. Pediculicide sprays are not necessary. If there is a concern about eggs surviving and hatching, items that cannot be washed may be placed in a plastic bag for 2 weeks.

Unless there is known resistance in the community, the first step in treatment is permethrin 1% or pyrethrins which are available over-the-counter. Permethrin 1% is the most studied and the least toxic of the pediculicides (lice-killers). Conditioners and silicone-based additives will interfere with permethrin, as will vinegar which is often used in an attempt to loosen nits from the hair shaft. When rinsing off pediculicides, use a sink instead of a shower or bath in order to reduce skin exposure. Using warm instead of hot water will minimize absorption. There are many other prescription medications that can be used if these over-the-counter products fail.
For those who cannot afford or who would prefer not to use pediculicides, wet combing or using suffocation methods can be attempted. An example of suffocation would be applying petroleum jelly to the hair and scalp and leaving it on overnight under a shower cap.

Misapplication is the leading cause of treatment failure. No treatment will kill all the eggs, so retreatment at specific intervals is recommended. Shaving, although effective, is not recommended. Any product that is meant to loosen nits can also damage the hair itself. Acetone, bleach, vodka, and WD-40 do not loosen nits. Please do NOT use kerosene, gasoline, or any other such flammable or toxic substance. They are not effective; they are just dangerous. Do not use products that are meant for animals.

Infested kids should definitely get treated, but they should not be kept out of school. The chance of transmission may not be zero, but it is lower than in other settings where head-to-head contact is more likely. One study at a school where over 14,000 live lice were found showed zero lice in the classroom carpeting. In another study, infested people spread lice to pillowcases only 4% of the time. And remember, head lice don’t carry any diseases, unlike mosquitoes which transmit a large number of diseases.

Just to put things in perspective, dust mites (see photo) thrive in bedding, mattresses, carpets, furniture…anyplace where there are tiny flakes of shedded human skin. Their fecal matter is a leading cause of allergies and asthma exacerbations. They are much more insidious than lice, but they don’t keep kids out of school.

The New Rules for Head Lice: Part 1

On July 26, the American Academy of Pediatrics updated its clinical report on head lice. It is common in school-aged kids, and it can be found all over the world. It affects all socioeconomic groups, and it can affect anyone regardless of hygiene. Mere mention of it can cause itchiness. It seems that resistance to standard treatments is on the rise. And yet, the AAP is pushing for kids to stay in school despite having lice. What’s going on?

Head lice are tan to grayish-white, and they are 2-3 mm long. Their eggs are even smaller. Their life cycle is about 3 weeks long. They feed by sucking tiny amounts of blood. Sensitization to their saliva as they feed is what makes us itchy, but this can take 4-6 weeks to develop. This means that by the time the diagnosis has been made, a kid in school has already been around other kids for a month. The good news is lice can only crawl; that means that they can only spread by direct contact. They cannot jump from head to head. This is also why brushing your hair will not prevent you from getting lice; it will only reduce the number of lice you are infested with. You are better off not sharing personal items (like hats, combs, brushes, etc.), but this is NOT an excuse to refuse to wear protective headgear. Lice that fall off or are combed off are usually injured or dead. Live lice and nits need our body heat to survive, so they are found close to the scalp (within 4-10mm). Farther than that, live lice only survive up to 48 hours, and eggs cannot hatch.

Many cases of “lice” are actually misdiagnosed. Dandruff, hair debris, dirt, and other insects have been mistaken for lice. This adds to the number of “resistant” cases. School screenings and forcing kids to stay home doesn’t reduce the incidence of live lice. Instead it means lost days in education and missed work days for the parents.

So what are we to do? The AAP does encourage parents to check their kids’ heads regularly and whenever the kids are itchy. Especially after sharing sleeping quarters, like at a camp, child care center, or sleepover. Using a louse comb on hair that is wet (with water, oil, or conditioner) is the easiest way to go about it. Eggs are most easily seen at the nape of the neck or behind the ears. Remember to look close to the scalp!

Please check back tomorrow, as I'll talk more about what to do if you find lice in your child's hair.
