E-cigarettes: Good news, bad news
Follow me at @JohnRossMD
Americans are confused about electronic cigarettes. A recent poll showed that the public was about evenly split between those who thought that electronic cigarettes, or e-cigarettes, were less harmful than conventional cigarettes, and those who believed that e-cigarettes were as bad as or worse than regular cigarettes.
Unfortunately, there is no long-term safety data about e-cigarettes. What information we do have suggests that e-cigarettes have a complex mix of potential harms and benefits.
E-cigarettes: Less deadly than regular cigarettes
First, the good news: e-cigarettes are almost certainly le...

3 reasons your child shouldn’t go “gluten-free” (unless your doctor says so)
Follow me at @drClaire
There is a puzzling and worrisome new phenomenon that I am seeing as a pediatrician: parents who are putting their children on gluten-free diets.
It’s puzzling because in the vast majority of cases it isn’t necessary — and it’s worrisome because, although parents are doing it because they think it’s healthy, a gluten-free diet can be very unhealthy for children.
Gluten is a protein found in wheat, rye, barley, and some other grains. It’s in bread and other baked goods, cereals, pastas — and in many other foods in small amounts. For people with celiac disease, even those small amounts ca...

Can aspirin protect against cancer?
The other day, a fit 50-year-old man came to me for a visit to review his health. As we discussed his (generally good) efforts to take care of himself, he said, “I’ve been wondering if I should take an aspirin every day. I read somewhere that it can prevent cancer.”
As a clinician, I really love it when people come in with questions that stretch my thinking. I have a stock set of answers to the “does aspirin prevent heart disease” question, but I didn’t have an easy answer to the cancer prevention question. What were the data? What should I be recommending? Is it true for everyone? Or maybe just for some people...

Diabetes drug pioglitazone could get personal: Neither panacea, nor peril
When I was in training, one of my beloved mentors declared, “I never use a drug until it’s been on the market for 20 years.” I was young enough then that I couldn’t fathom being a doctor for 20 years, let alone waiting two decades to use a new drug. As my career has progressed, I’ve seen many new drugs released to the market. Some of them are truly miraculous, bringing people longer, healthier, and more productive lives. Many of them have not withstood the test of time. More than a few have even been taken off the market. Even though the Food and Drug Administration diligently reviews each new medicine before it...

High blood pressure: Why me?
“I go to the gym, and I never add salt. So why do I have high blood pressure?” Despite its astonishing prevalence of one in three Americans, many people struggle with the diagnosis of high blood pressure, or hypertension. It’s worth exploring why, because being an active participant in your care is crucial for optimal blood pressure control.
Certain features make any diagnosis easier to accept:
First, people are more likely to accept a diagnosis if they have symptoms. A person with cough and fever will believe a diagnosis of pneumonia. But someone who feels fine would not.
Next, people more readily accept a diagnosi...

FDA warns parents about arsenic in rice cereal
Follow me at @drClaire
For years, rice cereal has been a go-to for parents when they start their babies on solid foods.
It’s time to change that.
In 2012, the Consumer Products Safety Commission (CPSC) issued a report warning about high levels of inorganic arsenic in rice and rice products. Rice plants are particularly good at absorbing arsenic from the soil, in particular because they grow in a lot of water. Inorganic arsenic is a common ingredient in pesticides and other products used in farming, and can linger in the soil for a long time after it is used. It can be poisonous. In high doses it is lethal, but even small...

Don’t shrug off shingles
If you had chickenpox as a kid, there is a good chance you may develop shingles later in life. “In fact, one in three is predicted to get shingles during their lifetime,” says Dr. Anne Louise Oaklander, director of the Nerve Unit at Harvard-affiliated Massachusetts General Hospital.
The same varicella-zoster virus that causes chickenpox also causes shingles. After the telltale spots of chickenpox vanish, the virus lies dormant in your nerve cells near the spinal cord and brain. When your immunity weakens from normal aging or from illnesses or medications, the virus can re-emerge. It then travels along a nerve to trigge...

Exercise: You may need less than you think
Regular exercise is one of the cornerstones for maintaining good health. Regular physical activity helps to prevent heart and blood vessel disease, diabetes, dementia, and even some types of cancer. But while the health benefits of exercise are indisputable, there is still a question about exactly how much exercise is needed to promote optimal health.
According to a recent article in The Journal of the American Medical Association by Thijs Eijsvogels and Paul Thompson, the answer may be “not as much as you might think.”
Every little bit of exercise counts
Drs. Eijsvogels and Thompson reviewed several published studies ...

Healing through music
The last time I had a mammogram, I got a big surprise — and it was a good one. A string quartet was playing just outside the doors of the breast imaging center, and my thoughts immediately shifted from “What are they going to find on the mammogram?” to “Is that Schubert, or Beethoven?” By the time my name was called, I had almost forgotten why I was there.
The unexpected concert was the work of Holly Chartrand and Lorrie Kubicek, music therapists and co-coordinators of the Environmental Music Program at Massachusetts General Hospital. But bringing music to hospital corridors is just a sideline for music therapist...

Kids and flu shots: Two common myths
As a pediatrician, I am really passionate about the flu shot. Influenza can be a nasty illness; every year, thousands of people are hospitalized with influenza and its complications, and some of those people die. The flu shot can protect my patients and their families, and I enthusiastically recommend it to all of them.
And yet many of them refuse, despite my best efforts. What is particularly frustrating is that many of them refuse because of misunderstandings about the flu shot. There is all sorts of misinformation out there, but here are the two most common myths:
1. The flu shot can make you sick. This is the one I hea...

Hidden cancer rarely causes out-of-the-blue clots in the bloodstream
Blood clots can be lifesavers when they form outside the bloodstream to stop bleeding from an injury. But they can wreak havoc when they form inside the bloodstream. A blood clot in a coronary artery can cause a heart attack. One in the brain can cause a stroke.
Blood clots that form in a leg vein cause a problem known as venous thromboembolism, or VTE. If the clot stays in the leg, it can cause swelling or pain. If it breaks away and travels to the lungs, it can cause a potentially deadly pulmonary embolism.
In about half of people who develop a VTE, doctors can identify what caused it. Common causes include an injury; su...

Grip strength may provide clues to heart health
A strong or weak hand grip carries more than just social cues. It may also help measure an individual’s risk for having a heart attack or stroke, or dying from cardiovascular disease.
As part of the international Prospective Urban and Rural Epidemiological (PURE) study, researchers measured grip strength in nearly 140,000 adults in 17 countries and followed their health for an average of four years. A device called a dynamometer was used to assess grip strength.
Each 11-pound decrease in grip strength over the course of the study was linked to a 16% higher risk of dying from any cause, a 17% higher risk of dying from...

Hospitalization after fainting can do more harm than good
One morning not long ago, my teenage daughter started to black out. After an ambulance ride to our local hospital’s emergency department, an electrocardiogram, and some bloodwork, she was sent home with a follow-up doctor appointment. We got the good news that Alexa is perfectly healthy, but should avoid getting too hungry or thirsty so she doesn’t faint again. And I’m feeling lucky that she didn’t need to be hospitalized, because a research letter in this week’s JAMA Internal Medicine points out that hospitalization for low-risk fainting can do more harm than good.
Doctors use something called th...

Precision medicine is coming, but not anytime soon
President Obama’s announcement of a Precision Medicine Initiative was one of the few items in this year’s State of the Union address to garner bipartisan support. And for good reason. Precision medicine, also known as personalized medicine, offers the promise of health care — from prevention to diagnosis to treatment — based on your unique DNA profile. Who wouldn’t want that?
We’ve already had a taste of precision medicine. Relatively low-tech therapies like eyeglasses, orthotic devices, allergy treatments, and blood transfusions have long been personalized for the individual. Genetic analysis o...

Menopause-related hot flashes and night sweats can last for years
According to conventional medical wisdom, menopause-related hot flashes fade away after six to 24 months. Not so, says a new study of women going through menopause. Hot flashes last, on average, for about seven years and may go on for 11 years or more.
The hormonal roller coaster that comes with the end of a woman’s childbearing years can trigger a range of symptoms. Up to 80% of women going through menopause experience hot flashes. Hot flashes, also known as vasomotor symptoms, are often described as a sudden sensation of heat in the chest, face, and head followed by flushing, perspiration, and sometimes chills. Whe...
