“With Summer Sun Come Signs of Danger

By JANE E. BRODY

With summer sun shining brightly across the United States (at least on most days), there is no better time to review the latest sobering findings on the damage that ultraviolet radiation can inflict on one’s skin and then take steps to prevent it.

A British research team reported in May in the journal Science that a quarter or more of cells in the skin of middle-aged people have suffered sun-induced DNA damage. Although the cells were outwardly normal, the mutations that occurred could be the first stages of cancer.

The researchers, led by Dr. Peter J. Campbell, a cancer geneticist at the Wellcome Trust Sanger Institute in England, examined the eyelid skin of four middle-aged adults — three were Western European and one was of South Asian descent — and found that hundreds of ostensibly normal cells had mutations linked to cancer, a number “way higher than we’d expect,” Dr. Campbell said. Clusters of these mutant cells, called clones, appeared in every 0.1 square inch of skin, with thousands of DNA mutations in each cell.

Although it is not known if the same rate of mutations occurs in sun-exposed skin elsewhere on the body, or in people of different ethnic backgrounds, or even how many of the mutations would progress to cancer, it is not a finding to dismiss lightly.

Douglas E. Brash, a biophysicist at Yale University School of Medicine who has studied ultraviolet damage to cells for more than 40 years and wrote a commentary on the British study, described the new findings as “a canary in a coal mine” and a warning to take the effects of ultraviolet radiation, whether from sunlight or tanning beds, more seriously.

It is especially important, he said, “to be very conscientious about protecting young children,” who are more susceptible than teenagers and adults to ultraviolet-induced mutations.

“A lot of damage occurs when people go to the beach,” Dr. Brash said. “While the body does a great job of repairing the damage and gets 99.9 percent of things right, every once in a while, you do get a mutation that may make a cell resistant to death, allowing it to form a clone that can become a cancer.”

Complicating the matter is that many people don’t understand the meaning of the S.P.F. rating listed on modern sunscreens — only 43 percent of 114 people surveyed at a dermatology clinic in Illinois last summer, according to a study in JAMA Dermatology. The rating, which stands for sun protection factor, is meant to reflect how well a product protects against sunburn, which should also reduce the risk of skin cancer and sun-induced skin aging. And less than a third of people use sunscreen regularly, according to the Centers for Disease Control and Prevention.

Dermatologists have long cautioned people not to rely too heavily on sunscreens, even products with the recommended S.P.F. rating of 30 or higher for summer sun protection. Few people who do use sunscreen use enough to achieve the level of protection measured in the laboratory, and few reapply it often enough. A better plan is to stay out of the sun, especially midday, and cover the skin when sun exposure is unavoidable.

Furthermore, a recently published study by Dr. Brash’s team at Yale showed that much of the harm to skin cells caused by ultraviolet radiation occurs hours after the exposure has ended. Even in the dark, substances formed during UV exposure continue to damage melanin, the pigment that gives skin its color, “exciting electrons, the energy from which gets transferred to DNA and can damage it in the same way that UV photons do,” Dr. Brash explained.

The British researchers chose eyelid skin for their study because it is readily available from an operation called blepharoplasty to remove drooping upper eyelids. Using a sophisticated technique called ultradeep sequencing, the researchers analyzed 234 biopsies from normal skin tissue for 74 cancer genes, and found a level of mutations “similar to that seen in many cancers.” A lot of the genetic changes they found resulted in what is called “driver mutations” that are capable of forming clones, a major step toward forming cancers.

Dr. Brash said skin on the hands, arms, cheeks and ears is likely to be even more heavily exposed to UV radiation than eyelid skin, and thus may have even higher levels of mutations, since the eyelids are shaded in part by the eye socket and sometimes sunglasses.

Nearly 25 years ago, Dr. Brash and his co-workers reported that UV light induced mutations in the critically important tumor suppressor gene called p53. They examined squamous cell skin cancers from 24 patients in New England and Sweden and found that 58 percent had mutations in p53, including a particular change in DNA structure “unique to UV.”

“You can’t buy a cream to get rid of mutations, so the best approach is to prevent the damage,” Dr. Brash said. “The new study presents a graphic picture of what’s going on in our skin, and might convince people to put on sunscreen and stay off the beach between 10 and 2.”

In its latest analysis of 1,000 commercially available sunscreens, the Environmental Working Group, a consumer advocacy organization based in Washington, rated sunscreens made with zinc oxide or titanium oxide high because “they provide strong sun protection with few health concerns” and “they don’t break down in the sun.” These substances are also more protective than other sunscreen ingredients against UVA rays, which can cause aging of the skin and immune suppression and characteristic sun-induced mutations in skin cells. The group’s complete 2015 sunscreen guide is available online at ewg.org/2015sunscreen.

Some consumers erroneously believe that choosing a more expensive sunscreen with a sky-high S.P.F. number like 70 or 100 will provide complete protection. However, the Food and Drug Administration has not determined that an S.P.F. of more than 50 has any added benefits.”

Eight Ways to Help Improve Your Child’s Vocabulary

The basis of a lifelong love and talent for learning may very well be a solid vocabulary. A strong vocabulary helps foster understanding, communication, and reading ability. That’s why parents should do what they can to help kids learn new words.

It may seem like common sense, but simple activities that can help your children expand their vocabulary often get pushed aside in day to day life. Consider these oft-overlooked ways to help your child develop an impressive vocabulary for years to come. Like it or not, you’re their teacher for all aspects of life!

Use Grown-Up Words in Normal Conversations

While you want your children to understand you, that doesn’t mean you can’t introduce “big” words into their vocabulary. Pepper your conversations with words your child probably won’t understand, but ones you’d likely use in conversation with an adult. Be sure to encourage your children to ask for clarification when they don’t understand something, and be prepared to pause and explain. By not dumbing-down the way you speak to your kids, they’ll pick up new words as you use them.

Let Your Child Tell the Story

Perhaps you read nightly to your child or take turns doing so. Of course, this is an excellent way to expand reading and vocabulary skills. However, on occasion, feel free to put the book down and ask your child to create a story to tell you. You may want to provide the setting (a pirate ship, for example) and a problem the characters must face (stranded on a haunted island). Then, let your child take the reigns to wherever his or her imagination leads.

Be sure to ask rhetorical questions during the story in order to introduce new words and concepts. If your child says, “The island was really hot,” you could ask, “Was it a tropical island?” Make a point to use new words in regular conversations thereafter. Forcing them to articulate their ideas will have them reaching for new words, and you can also help them along with suggestions.

Converse Regularly

In the same vein as having them tell stories, one way to improve your young child’s vocabulary is by simply talking more. Start conversations frequently. For younger kids like toddlers and babies, you can just give them a play-by-play of your daily activities: “Now I’m putting the cookies in the oven,” or, “I’m getting ready to go to work.”

Kids constantly absorb everything they hear. The more they hear you speak, the more you can teach them. As kids get older, give them a chance to speak more and practice their burgeoning vocabulary on you.

Play Word Games

We all know about Scrabble, but there are a variety of other word games you can play with children. Several old-school favorites are Boggle, Hangman, and Apples to Apples. Further, seize on the value of your smartphone by downloading apps like 7 Little Words, What’s the Word, and Word Stack. Apps like these can turn a few minutes waiting in line or riding in the car into an educational event. No doubt your kids are always trying to get ahold of your phone or tablet to play games, so these sorts of apps offer an opportunity to trick them into learning.

Label Household Items

Using post-it notes to label household items is a fantastic way to introduce young children to an array of words. This is great for youngsters who are still learning simple words. No matter what age they’re at—even if they’re not talking yet—children will learn to associate the written word with the item it’s attached to. Review each item with your child; pronounce the word and ask them (if old enough) to do the same. Lamps, clocks, beds, and kitchen items such as salt and pepper shakers are all items you can label—though anything in your home that your child interacts with works.

Pay More Attention to Your Kids’ Vocabulary

In short, you need to take a proactive role. If you want your children’s language skills to improve, take their vocabulary questions seriously. When they express curiosity about a word, be sure to teach the correct definition and pronunciation. Do your best to simplify definitions, but provide copious detail and examples. If you’re asked, “What does ‘gigantic’ mean?” say more than just “big.” Also provide a comparison: An elephant is “big” when compared to a person, but “gigantic” when compared to an ant.

Correct Mistakes With Care

It’s natural for children to mispronounce or misuse new words. However, it’s essential not to reprimand when they make such mistakes. Rather, applaud your child’s attempt, point out what they got right, and then review the proper way to use and or speak the word. The more fun and positive an experience, the more interested and able your children will be in expanding their vocabulary.

And Be Patient

You may need to repeat words and meanings multiple time before your child fully grasps the concept. This is completely normal. Further, if your neighbor’s child has twice the vocabulary yours does, it’s not worth stressing over. Remember, it’s not a contest, and their vocabulary is no attestation to your value as a parent.

Children develop at their own pace. The most important thing is to honor and balance their needs so that learning doesn’t become a struggle. While you want them to get ahead, you don’t want them to develop negative associations or undue stress with trying to do so.

Ronald Marx, professor of educational psychology and dean of education at the University of Arizona, recently said, “Exposure to books, exposure to language, explanations for things, all give kids opportunities for language growth and success at reading.” Take the time and energy needed to teach your kids – once you see their reading and writing skills improve, you’ll be glad you did.”

What We Need To Know About Enterovirus D68

October 8th, 2014 by KneeBees

 

Enterovirus-D68-MGN-graphic-jpg

We, as concerned parents at KneeBees Inc, wanted to share information below with as many people as possible.

First article is from www.webmd.com :

“A fast-spreading virus related to hand-foot-and-mouth disease is hospitalizing kids across the country.

The virus, called enterovirus D68 or EV-D68, was first discovered in 1962 in California. But until now, it has only been tied to smaller clusters of disease around the U.S.

This is the first time it’s caused such widespread misery, and it seems to be particularly hard on the lungs.

As of Oct. 6, the CDC has confirmed more than 590 cases of EV-D68 in 43 states and Washington, DC. All of the cases have been in children except for one adult case.

Some children with EV-D68 have died, but it’s unclear if the virus directly caused their deaths or was a contributing factor. Health officials are investigating.

A few children hospitalized with EV-D68 have also developed unexplained paralysis in their arms and legs, officials say. The CDC is doing further tests to figure out the cause of the paralysis.

“This could be just coincidental, so we can’t leap to the conclusion that enterovirus D68 is the cause of this paralysis,” says William Schaffner, MD, an infectious disease expert at Vanderbilt University in Nashville, TN. “It’s right at the top of our list of suspects, but we haven’t nailed it yet.”

“Many of us will have EV-D68,” says Michael Fine, MD, director of the Rhode Island Department of Health, in a statement. “Most of us will have very mild symptoms, and all but very few will recover quickly and completely. The vast majority of children exposed to EV-D68 recover completely.”

We reached out to pediatricians and infectious disease specialists to find out what parents should know about this respiratory illness.

What are the symptoms of D68 infection?

Most viral infections start out with a fever, cough, and runny nose, but D68 doesn’t seem to follow that classic pattern, says Mary Anne Jackson, MD. She’s the division director of infectious disease at Children’s Mercy Hospital in Kansas City, MO, the hospital where the first cases were identified.

“Only 25% to 30% of our kids have fever, so the vast majority don’t,” Jackson says. Instead, kids with D68 infections have cough and trouble breathing, sometimes with wheezing.

They act like they have asthma, even if they don’t have a history of it, she says. “They’re just not moving air.”

Why so many cases now?

The typical enterovirus season runs from July through October, so we’re in an enterovirus season, says Jackson.

What’s unusual about this one is that it’s a virus that hasn’t widely spread through the U.S. before.

“If you have a new virus that has not widely circulated, most people are going to be susceptible,” Jackson says.

The spreading of the virus coincided with the start of the new school year. Many hospitals noticed a big uptick in cases when kids went back to their classrooms.

Unfortunately, Jackson says, the outbreak may get worse before it gets better.

“In order for this virus to stop, it’s going to have to infect enough of the population to provide immunity and essentially burn itself out,” she says.

Who’s at greatest risk?

Recent cases have been in children ages 6 months to 16 years, with most hovering around ages 4 and 5, the CDC says.

And while many kids are coming down with milder symptoms, the virus seems to be hitting children with a history of breathing problems particularly hard.

Two-thirds of those hospitalized at Children’s Mercy had a history of asthma or wheezing, Jackson says.

“We made sure that primary care providers are in touch with their patients with asthma, so those have an active asthma plan and know what to do if they get into trouble,” she says.

How is the infection treated?

Because it’s caused by a virus, and not bacteria, antibiotics don’t help.

There is no vaccine to prevent it and no antiviral medication to treat it, says Andi Shane, MD. She’s the medical director of hospital epidemiology and associate director of pediatric infectious disease at Children’s Healthcare of Atlanta.

Shane says her hospital is admitting about 100 kids a week with symptoms that are consistent with D68 infections.

She says the virus is treated with supportive care.

“The main thing is giving supplemental oxygen to the children who need it,” she says. Children may also get medications, such as albuterol, which help relax and open the air passages of the lungs.

Those with the most critical cases have needed ventilators to help them breathe.

When do kids need medical attention?

Most kids who get D68 infections will have a milder course of disease that just needs extra TLC, including lots of rest and plenty of fluids.

But it’s time to head to the doctor’s office or emergency room “if there’s any rapid breathing, and that means breathing more than once per second consistently over the span of an hour. Or if there’s any labored breathing,” says Roya Samuels, MD. She’s a pediatrician at Steven & Alexandra Cohen Children’s Medical Center in New Hyde Park, N.Y.

Labored breathing, Samuels says, means kids are using smaller muscles around the chest wall to help move air in and out of their lungs.

“If you see the skin pulling in between the ribs or above the collarbone, or if there’s any wheezing, those are clear signs that a child needs to be evaluated,” she says.

How do you catch it?

The bad news is that enteroviruses, which are thought to cause between 10 million and 15 million infections in the U.S. each year, are pretty hardy, says Stephen Morse, PhD. He’s an infectious disease expert at Columbia’s Mailman School of Public Health, in New York City.

The “entero-“ part of their name means the viruses can survive stomach acid and infect the gut, as opposed to their cousins, the rhinoviruses, which can’t.

He says these germs can live on surfaces for hours and maybe as long as a day, depending on the temperature and humidity.

“It is a pretty tough virus,” he says.

The virus can be found in saliva, nasal mucus, or sputum, according to the CDC.

Touching a contaminated surface and then rubbing your nose or eyes is the usual way someone catches it. You can also get it from close person-to-person contact.

Protect yourself with good hand-washing habits. Tell kids to cover their mouth with a tissue when they cough. If no tissue is handy, teach them to cough into the crook of their elbow or upper sleeve instead of their hand.

Common disinfectants and detergents will kill enteroviruses, Morse says, so clean frequently touched surfaces like doorknobs and toys according to manufacturers’ directions.

EV68-infographic

From CDC

Additonal information below is taken directly from CDC website at www.cdc.gov

“Enterovirus D68 (EV-D68) is one of more than 100 non-polio enteroviruses. This virus was first identified in California in 1962.

What are the symptoms of EV-D68 infection?

EV-D68 can cause mild to severe respiratory illness.
Mild symptoms may include fever, runny nose, sneezing, cough, and body and muscle aches.
Severe symptoms may include wheezing and difficulty breathing. See EV-D68 in the U.S., 2014 for details about infections occurring this year.
Anyone with respiratory illness should contact their doctor if they are having difficulty breathing or if their symptoms are getting worse.

How does the virus spread?

Since EV-D68 causes respiratory illness, the virus can be found in an infected person’s respiratory secretions, such as saliva, nasal mucus, or sputum. EV-D68 likely spreads from person to person when an infected person coughs, sneezes, or touches a surface that is then touched by others.
What time of the year are people most likely to get infected?

In the United States, people are more likely to get infected with enteroviruses in the summer and fall. Cases are likely to decline later in the fall.
Keep your child from getting and spreading Enterovirus D68

How common is EV-D68 in the United States?

In general, a mix of enteroviruses circulates every year, and different types of enteroviruses can be common in different years. Small numbers of EV-D68 have been reported regularly to CDC since 1987. However, this year the number of people reported with confirmed EV-D68 infection is much greater than that reported in previous years. See EV-D68 in the U.S., 2014 for details about infections occurring this year.

Who is at risk?

In general, infants, children, and teenagers are most likely to get infected with enteroviruses and become ill. That’s because they do not yet have immunity (protection) from previous exposures to these viruses. We believe this is also true for EV-D68. Adults can get infected with enteroviruses, but they are more likely to have no symptoms or mild symptoms.
Children with asthma may have a higher risk for severe respiratory illness caused by EV-D68 infection.
How is it diagnosed?

EV-D68 can only be diagnosed by doing specific lab tests on specimens from a person’s nose and throat.
Many hospitals and some doctor’s offices can test ill patients to see if they have enterovirus infection. However, most cannot do specific testing to determine the type of enterovirus, like EV-D68. CDC and some state health departments can do this sort of testing.
CDC recommends that clinicians only consider EV-D68 testing for patients with severe respiratory illness and when the cause is unclear.

What are the treatments?

There is no specific treatment for people with respiratory illness caused by EV-D68.
For mild respiratory illness, you can help relieve symptoms by taking over-the-counter medications for pain and fever. Aspirin should not be given to children.
Some people with severe respiratory illness may need to be hospitalized.
There are no antiviral medications currently available for people who become infected with EV-D68.

How can I protect myself?

You can help prevent yourself from getting and spreading EV-D68 and other respiratory illnesses by following these steps:
Wash hands often with soap and water for 20 seconds.
Avoid touching eyes, nose and mouth with unwashed hands.
Avoid close contact such as kissing, hugging, and sharing cups or eating utensils with people who are sick.
Cover your coughs and sneezes with a tissue or shirt sleeve, not your hands.
Clean and disinfect frequently touched surfaces, such as toys and doorknobs, especially if someone is sick.
Stay home when you are sick.
Also, see an infographic that shows these prevention steps.
There are no vaccines for preventing EV-D68 infections.

What should people with asthma and children suffering from reactive airway disease do?

Children with asthma are at risk for severe symptoms from EV-D68 and other respiratory illnesses. They should follow CDC’s guidance to maintain control of their illness during this time.
CDC recommends:
Discuss and update your asthma action plan with your primary care provider.
Take your prescribed asthma medications as directed, especially long term control medication(s).
Be sure to keep your reliever medication with you.
Get a flu vaccine when available.

If you develop new or worsening asthma symptoms, follow the steps of your asthma action plan. If your symptoms do not go away, call your doctor right away.
Parents should make sure the child’s caregiver and/or teacher is aware of his/her condition, and that they know how to help if the child experiences any symptoms related to asthma.”
