Another Study Finds No Vaccine –Autism Connection

2:00

A new study, using insurance records for nearly 96,000 U.S. children, found no link between the measles - mumps – rubella (MMR) vaccine and autism – even among children who are at an increased genetic risk.

Experts are hoping that this study, along with several other studies on the risks of autism and the MMR vaccine, will reassure parents that the vaccine is safe.

While the original 1998 study associating the vaccine with autism has been found fraudulent, many parents continue to worry that the vaccine could be a trigger for autism; particularly parents that already have a child with autism.

"Research has shown that parents of kids with autism spectrum disorders are more likely to delay vaccinating their younger children," said Dr. Bryan King, an autism researcher at the University of Washington, in Seattle.

"Basically, they wait until the developmental dust has settled, and it looks like their child will be unaffected (by autism)," said King, who wrote an editorial published with the study.

Health officials are concerned that children who do not receive the MMR vaccine are putting other children at risk for serious diseases. They point to the recent measles outbreaks as one example. So far this year, 162 people have been sickened across 16 states and Washington D.C. according to the U.S. Centers for Disease Control and Prevention (CDC).

Scientists are working hard to find out why there has been an increase in autism over the last decade.  It's known that genes make certain children more vulnerable to autism -- that's why kids with an affected older sibling are at higher-than-average risk. But environmental factors also have to play a role, experts believe.

Based on years of research, the MMR vaccine is not that trigger, according to health experts. "Every study that's looked at this, through every strategy they've used, has found no signal," King said.

According to King, it's natural for parents with a child who has autism to want to reduce their younger kids' risk.

"Everyone believes there have to be environmental factors contributing to the exponential rise we've seen in ASDs," he said. "But we don't understand what those factors are yet."

Researchers are finding clues, though. And more and more, they suspect that prenatal brain development is the critical period, King said.

The new findings are based on insurance records for nearly 96,000 U.S. children with an older brother or sister; 2 percent had an older sibling with an autism spectrum disorder.

Of the children with an affected sibling, 7 percent had an autism spectrum disorder themselves, compared to just under 1 percent of other kids. There was no evidence, though, that the MMR vaccination raised the risk of autism in either group of children, Jain said.

Among kids with an affected sibling, those who'd received one MMR dose by age 2 were actually one-quarter less likely to be diagnosed with an autism spectrum disorder, the study found. The odds were even lower among those who'd received two doses by age 5.

The study did not reveal any evidence that the MMR vaccine offered any protective influence over autism, only that it was not associated with an increase of risk for autism.

More studies are in the works to find the source of autism. Environmental factors are playing a key role in many of those studies as well as genetic links.

It’s understandable that parents would worry about vaccinations of any kind having a negative effect on their child, but more and more studies confirm that the MMR vaccine is one that parents can eliminate from their list of concerns.

This study was reported in the April 21 issue of the Journal of the American Medical Association.

High Cholesterol Putting Kids at Risk for Heart Attack

2:00

Abnormally high cholesterol levels are putting American children at higher risk for a heart attack or stroke later in life. One in five kids has high cholesterol according to a review of 2011-2014 federal health data compiled by researchers at the U.S. Centers for Disease Control and Prevention (CDC).

Overall, slightly more than 13 percent of kids had unhealthily low levels of HDL ("good") cholesterol -- the kind that actually might help clear out arteries. The CDC says just over 8 percent had too-high levels of other forms of cholesterol that are bad for arteries, and more than 7 percent had unhealthily high levels of "total" cholesterol.

Obesity was seen as a major contributing factor, the CDC said. For example, more than 43 percent of children who were obese had some form of abnormal cholesterol reading, compared to less than 14 percent of normal-weight children.

Not surprisingly, rates of abnormal cholesterol readings rose as kids aged. For example, while slightly more than 6 percent of children aged 6 to 8 had high levels of bad cholesterol, that number nearly doubled -- to 12 percent -- by the time kids were 16 to 19 years of age, the CDC said.

Knowing how obesity can impact the heart, cardiologists were not shocked by the findings.

"When one looks at the data it is clear that the obesity epidemic is responsible for a substantial portion of these abnormal cholesterol values," said Dr. Michael Pettei, who co-directs preventive cardiology at Cohen Children's Medical Center in New Hyde Park, N.Y. "Approximately one-third of U.S. children and adolescents are either overweight or obese.

"Clearly, the American Academy of Pediatrics' (AAP) recommendations to screen all children for cholesterol status, and to take measures to prevent and manage obesity, are more appropriate than ever," he said.

Dr. Kevin Marzo, chief of cardiology at Winthrop-University Hospital in Mineola, N.Y., agreed.

"Abnormal cholesterol is a key modifiable risk factor for developing cardiovascular disease, including heart attack and stroke, in adulthood," he said. "This study confirms that preventive strategies must start in childhood, including healthy eating habits, regular exercise, and maintaining ideal body weight."

The AAP recommends that all children begin having their cholesterol checked between the ages of 9 and 11.

An acceptable total cholesterol level for a child is below 170 with LDL below 110. A borderline reading in total cholesterol is 170-199 with LDL between 110-129.  And a high classification in total cholesterol is above 200 with LDL above 130.

There may be other reasons a child can have high cholesterol such as diabetes, liver disease, kidney disease or an underactive thyroid. If an initial test shows high cholesterol, your pediatrician will check your child’s blood again at least 2 weeks later to confirm the results. If it is still high, the doctor will also determine if your child has an underlying condition.

Some children can also have high cholesterol that is passed down through families.  It’s called familial hypercholesterolemia and is an inherited condition that causes high levels of LDL cholesterol levels beginning at birth, and heart attacks at an early age. Any child with a family history of high cholesterol should begin having his or her levels in infancy.

The findings were published Dec. 10 as a Data Brief from the CDC's National Center for Health Statistics.

New Guidelines for Treating Acne

2.30 to read

I recently ran into a friend I hadn’t seen in about 5 years. We were catching up on each other’s lives when her teenage son joined us. The last time I saw “John” he was about 11 years old and full of pre-teen energy and curiosity. This time however, he was quiet and kept his head down when he said hello. When he finally looked up, I saw why he had been avoiding full-face eye contact. “John” had a pretty severe case of acne. Not a few pimples, but entire areas on his face that were red and dotted with large pustules and cysts.  It looked painful.

Typically, acne isn’t a serious medical condition. It comes and goes throughout life and is more of an annoyance than anything else. For some though, acne can cause emotional distress and lead to scarring of the skin and psyche.

Fortunately, there are many over-the-counter (OTC) medications that when combined with a consistent face cleaning routine, keep breakouts to a minimum.

But for some people, teens in particular, acne can progress to the point where OTC medications don’t control the problem. Pediatricians are often called upon to help teens come up with a plan of treatment. 

There is a range of medications that can clear up even severe cases of acne, according to the American Academy of Pediatrics (AAP). Writing in the May issue of its journal Pediatrics, the group throws its support behind new guidelines from the American Acne and Rosacea Society that detail how to treat acne in children and teens of all ages.

That "all ages" part is important because acne is becoming more and more common in pre-teens, too, said Dr. Lawrence Eichenfield, the lead author of the AAP report. One study of 9- and 10-year-old girls found that more than three-quarters had pimples.

A possible reason for why kids are experiencing breakouts at a younger age is that, on an average, boys and girls are starting puberty earlier than in past generations says Eichenfield.

According to the AAP, milder cases of acne can be managed with OTC soaps, washes, lotions or gels containing benzoyl peroxide.  Another common ingredient used to battle acne is salicylic acid. Department stores now have sections of aisles filled with these types of products making them easy to find.

But what if the OTC medications do not help clear up your teen’s acne? The AAP recommends going to the next step of trying a topical retinoid. Retin-A, Avita and Differin are the most commonly prescribed treatments. They are vitamin A derivatives and work by speeding up skin cell turnover, which helps unclog pores.

The main side effects of all the topical treatments are skin irritation and dryness, the AAP said.

If the acne is considered moderate to severe and other treatments have failed to work, the next step may be oral antibiotics. When pores become clogged with oil and skin cells, bacteria can grow in the pore and cause inflammation. Antibiotics help by killing bacteria and soothing inflammation.

But, Eichenfield said, "it's important to use antibiotics appropriately."

Antibiotics can have their own set of problems and should be used with caution. The overuse of antibiotics has made some acne causing bacteria more resistant. Other side effects can be stomach upset, dizziness and, in girls - yeast infections.

When all else fails and acne is severe, the prescription drug isotretinoin may be an option. Brand names include Roaccutane (formerly known as Accutane) and Claravis.

The drug is very effective, but it can cause birth defects, so girls and women have to use birth control and get regular pregnancy tests if they go on the medication. Isotretinoin also has been linked to inflammatory bowel disease, depression and suicidal thoughts in some users, although it's not clear the drug is to blame, the AAP said. (Severe acne itself can cause depression and suicidal thoughts, for example.) Other side effects can include sun-sensitivity, dry eyes, mouth, lips nose and skin as well as itching, nosebleeds and muscle aches.

Why do we get acne?

Acne occurs when hair follicles become plugged with oil secretions, dead skin cells and sometimes bacteria. The most common areas on the body where acne erupts are the face, neck, chest, back and shoulders. It takes time for acne lesions to heal and quite often another breakout will appear as one is finally clearing up.

Hormones and certain medications can play a role in triggering acne. Whether diet is a factor is still up for debate. "The idea that food plays a role became relegated to myth," Eichenfield said. But recently, he added, some researchers have been revisiting the issue. There is some evidence that a sugary diet may promote acne, for example. But for now, it's not clear whether any diet changes will actually help keep kids' skin clear, Eichenfield said.

Stress may not cause acne but it can aggravate it.

Keeping skin pores open and unclogged is the key ingredient to preventing acne. While it may seems that scrubbing your face, using astringents and drying masks would help do that, they aren’t generally recommended. Too much washing and scrubbing can irritate the skin.

It's best to wash your face gently twice a day, with a soap-free pH-balanced cleanser, the AAP said. Facial toners -- which commonly come in pre-packaged acne regimens -- can help clear away oil. But the group suggested going easy on toners, since they can irritate the skin.

One myth that seems to never go away is that tanning and more time in the sun is good for acne. A sunburned face may look better to you because your whole face is red instead of just certain areas. Too much sun can actually make acne worse for some people. It also ages your skin and can cause skin cancer. Certain medications (including some for acne treatment) can make your skin very sensitive to the sun’s rays. Always use a “face-friendly” sunscreen that doesn’t clog the pores.

I really felt bad for my friend’s son when I saw how miserable he was. To me he’s still handsome and has a bright and interesting future ahead of him. I’m not so sure that he thinks that, at least not until his acne is under control.

The bottom line, Eichenfield says, is that many treatment options are available. "There's no reason that children have to live with acne that is severe and troubling to them.”

Teens & Headaches Go Together

I just read an interesting study about teenagers with headaches. About one to two percent of adolescents have chronic daily headaches, defined as greater than 15 headache days per month for greater than three months.

Once school begins, teens stress levels increase with each week of school, and with that come more complaints of chronic headaches. It is not unusual for me to see several teens a week who complain that they have headaches every day. Despite these persistent headaches, the majority of adolescents continue to participate in their school activities, sleep well once they fall asleep and spend their weekends doing whatever it is that teens all do. I see very few teens who look like they are in “severe” pain, although they state that their head is “killing” them while they chatter away about where it hurts, and how often it hurts etc. It is quite reassuring to watch their faces and expressions as they go into detail about their headaches. In these cases it is important to obtain a good history to rule out any underlying pathology, as well as to inquire about family history of migraines. In this study the authors followed adolescents ages 12 – 14 years who met criteria for chronic daily headaches. They followed the group after both one and two years, and then again after eight years. The results showed that after one year 40 percent of adolescents still complained of chronic headaches. After two years, only 25 percent reported headaches. After eight years, only 12 percent reported chronic headaches. Most participants reported substantial or some improvement in headache intensity and frequency during the eight-year follow-up. The most significant predictor for ongoing problems with headaches was onset of chronic headaches before the age of 13 years. For the most part 75 percent of adolescents with chronic daily headaches improved over the eight-year period, which is quite reassuring. This study just seemed to confirm that teens and headaches go together. If a good history and physical exam is performed and there seem to be no underlying problems that contribute to their headaches, it is best to discuss the natural history of chronic headaches. I think it is important to spend time with adolescents to explore ways to alleviate stress as a trigger for chronic daily headaches. Basic changes in lifestyle such as healthy eating, regular exercise, and a good night’s sleep will often help reduce headaches. Relaxation techniques and cognitive behavioral therapy may also be utilized. At least we know that the headaches reduce with time, maybe just a maturational process, like many things! That’s your daily dose, we’ll chat again tomorrow.

Does Birth Order Impact Children’s IQ or Personality?

2:00

In 1982, “The Birth Order Book” by psychologist, Dr. Kevin Leman, was published and quickly became a best seller. The premise was that there are four personality types based on a person’s birth order. Since then, other authors have written extensively about whether one’s birth order has a lasting effect on our personalities, IQ, successes or failures in life and other physical, emotional or psychological traits.

Now, a large study from the University of Illinois says there may be a slight benefit to being the first born in a family, but the difference is miniscule and offers no real advantage or disadvantage in how a person’s life plays out.

Psychology professor Brent Roberts, along with former postdoctoral researcher Rodica Damian, conducted an analysis of 377,000 high school-age students to test the assumption.

The researchers found that first-born children do tend to have a slightly higher IQ and often display differing personality traits than their siblings later, but the differences are so small between the first- born and the later-born that they really have no significant impact on their lives.

Their analysis determined first-borns had a one-point IQ advantage over their following siblings, statistically significant in scientific terms but meaningless in suggesting any practical effects on a person's life.

Previous studies have been conducted on the same topic, but most had a small sample size – that’s why Roberts believes this study is noteworthy.

"This is a conspicuously large sample size," he says.  "It's the biggest in history looking at birth order and personality."

Looking at personality differences, the study found first-borns tended to be slightly more extroverted, conscientious, agreeable and less anxious that later-borns, but that those differences were on a scale of 0.02, or "infinitesimally small," Roberts notes.

Statistical differences can be more or less valuable depending on what is being examined.

"In some cases, if a drug saves 10 out of 10,000 lives, for example, small [statistical] effects can be profound," Roberts said. However, he noted, when it comes to personality traits a 0.02 difference is so small as to be invisible, something that wouldn't be apparent to the naked eye.

"You're not going to be able to sit two people down next to each other and see the differences between them," he says. "It's not noticeable by anybody."

Damien, who is now a now a professor of psychology at the University of Houston, says she and Roberts controlled for factors that might skew results, including a family's economic level, the number of siblings and their relative ages.

Whether a child’s birth order has any effect on his or her personality or IQ is still somewhat controversial among child psychologists and psychiatrists.  Some believe it has its place in child rearing and others think it is simply pop culture. Most would probably agree however, that a child’s later personality and IQ are typically based on more complicated factors than whether they were the first, middle, last or only child in the family.

The study was published in the Journal of Research in Personality.

Young Male Athletes, Parental Pressure and Doping

1:45

When 129 young male athletes, whose average age was 17, were asked what would make them consider “doping” as a way to boost their athletic ability – the majority said parental pressure.

A new study from the University of Kent in England asked the young male athletes about their attitudes on "doping" -- the use of prohibited drugs, such as steroids, hormones or stimulants, to increase athletic competence.

These substances, sometimes called performance-enhancing drugs, can potentially alter the human body and biological functions. However, they can be extremely harmful to a person's health, experts warn.

The study group was also asked about four different aspects of perfectionism. The areas were: parental pressure; self-striving for perfection; concerns about making mistakes; and pressure from coaches.

Only parental pressure was linked to positive feelings about doping among the athletes, the study authors found. Although the study was small, it did point out how important demanding expectations from parents can be to kids. 

Lead author of the study, Daniel Madigan, a Ph.D. student in the university's School of Sport and Exercise Sciences, said the findings suggest that parents need to recognize the consequences of putting too much pressure on young athletes in the family.

"The problem of pressure from parents watching their children play sports is widely known, with referees and sporting bodies highlighting the difficulties and taking steps to prevent it," Madigan said in a university news release.

"With the rise of so-called 'tiger' parenting-- where strict and demanding parents push their children to high levels of achievement -- this study reveals the price young athletes may choose to pay to meet their parents' expectations and dreams," Madigan added.

The researchers only focused on young men for this study but plan to investigate if the same result will occur with young female athletes, and if there are differences between athletes in team versus individual sports.

The study findings are scheduled for publication in the April print issue of the Journal of Sports Sciences.

Concussion’s Effects May Linger in Kids

2.00 to read

Concussions have been in the news a lot lately, particularly when they relate to children. Awareness about the dangers of concussions has changed how schools, coaches and parents watch for and treat this kind of injury. A new study released this week points out that some concussion side effects can last longer than thought.

Children who suffer even a mild concussion can have attention and memory problems a year after their injury.

The study results were published in the Archives of Pediatrics and Adolescent Medicine, and suggest that problems such as forgetfulness, dizziness,  and fatigue may linger for up to about 20 percent after an accident.

Forgetfulness, difficulty paying attention, headaches and fatigue were more common in study children who lost consciousness or who had other mild head trauma that caused brain abnormalities on imaging tests, compared with kids who didn't get knocked out or who had normal imaging test results.

Longer lasting symptoms were not determined since the study only followed children for a year after their injury. For that year though, children who had injury-related symptoms experienced "significant functional impairment in their daily lives."

"What parents want to know is if my kid is going to do OK. Most do OK, but we have to get better at predicting which kids are going to have problems," said study author Keith Owen Yeates, a Neuropsychologist at Ohio State University's Center for Biobehaviorial Health.

Children who have concussion symptoms may need temporary accommodations such as extra time taking school tests, or wearing sunglasses if bright light gives them headaches, Yeates said.

Most of the children in the study received their concussion from a sports related injury or fall, but about 20 percent had a mild brain trauma injury from a traffic accident or some other cause.

The study included 186 children, aged 8 to 15, with mild concussions and other mild brain injuries treated at two hospitals in Cleveland and Columbus, Ohio. The reports are based on parents' reports of symptoms up to 12 months after the injuries.

The brain injuries studied were considered mild because they involved no more than half an hour of unconsciousness; 60 percent of kids with concussions or other brain trauma had no loss of consciousness.

Overall, 20 percent who lost consciousness had lingering forgetfulness or other non-physical problems a year after their injury; while 20 percent who had abnormal brain scans had lingering headaches or other physical problems three months after being injured.

The study adds to research showing that mild traumatic brain injuries, including concussions "should not necessarily be treated as minor injuries," Dr. Frederick Rivara, Archives' editor, said in a journal editorial.

More information is needed to determine who is most at risk for lingering problems after these injuries, and to determine what type of treatment and activity restriction is needed, said Rivara, a pediatrician and University of Washington researcher.

The Centers for Disease Control and Prevention (CDC) defines a concussion as a type of traumatic brain injury caused by a bump, blow, or jolt to the head that can change the way the brain normally works. Concussions can also occur from a blow to the body that causes the head to move rapidly back and forth. Even a “ding,” “getting your bell rung,” or what seems to be mild bump or blow to the head can be serious.

According to the CDC, if your child has any symptoms of a concussion - which include different sleeping patterns, mood changes or problems with cognitive processes - you should bring them to a medical professional. If the child is having a headache that won't go away, weakness or decreased coordination, vomiting or nausea, slurred speech, will not nurse or eat and/or is crying and cannot be consoled, they need to be taken to a hospital immediately.

Acne Gel Linked to Rare Side Effect

1:45

Nearly all teens will get acne at one time or another. For those that get severe acne, it can be devastating to their self-esteem. While acne isn’t a serious health problem, it’s not something that is easy to hide.

For a lot of teens, over-the–counter face washes and drying agents help keep acne under control. For more serious acne, families often turn to a dermatologist for prescription medicine.

In certain people, Aczone- the skin gel version of the drug Dapzone -may lead to a rare blood disorder called methemoglobinemia according to a new study.

That’s what a 19 year-old female in Pittsburgh was using to treat her acne before she entered the emergency room with a headache, shortness of breath, and blue lips and fingers. At first, her doctors were at a loss as to what was causing her condition.

The patient had been using a “pea-size” amount of Aczone on her face twice daily during the previous week and didn’t think to tell the doctors about it when questioned about any medications she was taking.

"We went over all her meds and herbal supplements," said Dr. Greg Swartzentruber, a medical toxicology fellow at the University of Pittsburgh Medical Center. "And we couldn't come up with a cause, even after interviewing her and her family. Aczone was just never mentioned."

Topical medicines can have systemic adverse effects on people, but many patients don’t think about topical creams or gels when asked about medications they are on by their doctor.

The study authors noted that prior research has shown that Dapsone pills, in very rare instances, can trigger methemoglobinemia, the abnormal production of a red blood cell protein that delivers oxygen throughout the body.

But the current case appears to be the first time that this condition has been associated with Aczone, the skin gel version of Dapsone, they said.

Dapzone pills have been available for decades and were once used to treat leprosy. In 2005, the FDA approved Aczone - the 5 percent topical cream – for acne treatment use. Dapzone and Aczone have been very effective for treating acne.

However, if someone has the rare genetic defect that makes it impossible to properly metabolize the drugs, it can cause serious health problems.

"The blood cells blow up, basically," said Dr. Darrell Rigel, a clinical professor of dermatology with New York University Medical Center in New York City. Rigel added. "The prevalence of this deficiency is very low. Maybe it affects less than 1 percent of the population, but those that have it can end up with serious problems."

Doctors were finally able to diagnose the young woman’s illness through a urine test. She was successfully treated and released from the hospital after two days.

Rigel noted that dermatologists who prescribe Aczone have a responsibility to always screen patients for this issue. "And patients have to know that when they're asked to give their drug history they can't forget their topicals," he said.

The young woman’s case was described in a letter published in the New England Journal of Medicine.

Gut Bacteria Linked to Kid’s Asthma

2:00

Four types of gut bacteria may reduce a child’s risk of developing asthma according to a recent Canadian study.

Most Infants - but not all - typically receive these bacteria from their environment or mothers after birth. Sometimes babies are given antibiotics that not only kill bad bacteria, but eliminating the helpful gut bacteria as well.

"We now have particular markers that seem to predict asthma later in life," lead researcher Brett Finlay, a professor of microbiology and immunology at the University of British Columbia in Vancouver, said during a news conference Tuesday.

"These findings indicate that bacteria that live in and on us may have a role in asthma," he said. This seems to happen by 3 months of age in ways that still aren't clear.

Previous studies have shown that certain environmental bacteria, such as living on a farm or having pets, appear to decrease the chances of children developing asthma.

Another interesting clue to asthma is what populations seem to have the most cases. Instances of asthma have increased in western countries where hygiene standards are higher. "Ironically, it has not increased in developing countries," Finlay said.

Organizations that specifically track asthma cases around the world say that as developing countries move from poverty into low-to-middle income, cases of childhood asthma begin to increase.

The "hygiene hypothesis," says environments that are too clean may actually impede development of the immune system.

For the study, Finlay and colleagues looked for four types of bacteria in stool samples of 319 infants at 3 months of age. The bacteria are called FLVR (Faecalibacterium, Lachnospira, Veillonella and Rothia).

The researchers found that 22 children with low levels of these bacteria at age 3 months also had low levels at age 1 year.

These 22 children are at the highest risk of developing asthma, and eight have been diagnosed with the respiratory disease so far, the researchers said.

Study co-author Dr. Stuart Turvey, professor of pediatric immunology at the University of British Columbia, said at the news conference that it's "not surprising how important early life is."

In the first 100 days of life, gut makeup influences the immune response that causes or protects kids from asthma, he said.

Turvey also noted that testing infants for these bacteria might help identify children who will be at high risk for asthma. Babies without FLVR bacteria could be followed and treated earlier for better outcomes he said.

Whether giving kids probiotics -- good bacteria -- might reduce asthma risk isn't known, the researchers said. Turvey said the probiotics available in over-the-counter forms do not include the four bacteria identified in this study.

"Studies like ours are identifying specific bacteria combinations that seem to be missing in the children at the highest risk of asthma," he said. "The long-term goal is to see if we could offer these bacteria back, not the general nonspecific probiotics."

Finlay said the findings need to be replicated in larger groups and in different populations. He said the researchers also want to know if all four bacteria are protective, or just one or two.

As with most studies, the results did not prove a cause and effect only a connection, in this case between gut bacteria and asthma risk in children.

The report was published online in the journal Science Translational Medicine.
