An epidemic of nearsightedness?
A story making the media rounds this month is that more children and young adults are being diagnosed with myopia, or nearsightedness, and smartphones might be to blame.
I couldn’t find the actual study online, but it came out of the UK where a laser eye surgeon claims there has been a 35% increase in nearsightedness–screen sightedness, he has dubbed it–since 1997. He believes smartphones are a cause, and warns that the problem will only get worse.
Without being able to see the actual study, it’s difficult to assess this claim. Perhaps as a Lasik surgeon, … Continue reading
Too many CT scans ordered on children
This morning I read a post by a pediatric intensive care (PICU) doctor who admitted too many CT scans are still being given to children, despite recent evidence that radiation exposure from the scans carries a not insignificant future risk of cancer.
I posted about the results of this study a couple of months ago: Children are more “radiosensitive” than adults; CT scanners can vary dramatically in the amount of radiation exposure; and radiation exposure is cumulative–more CT scans relate to a higher risk.
This doctor focused on the overuse of … Continue reading
The “sleep supplement”
I am a chronically poor sleeper, and I have tried melatonin, the sleep supplement, in the past. I have friends that swear by it, but it never worked for me.
Plus, I could never get a straight answer from any source about the therapeutic dosage – 1 mg, 3 mg, 5 mg, 10 mg? Should I only take it as needed, or is melatonin safe to take every night, forever?
As a supplement (it’s actually a hormone), melatonin falls under the extremely loose guidelines of the Dietary Supplement Health And Education Act (DSHEA) of 1994. It … Continue reading
Poisoning deaths are on the rise
Why? Drugs. And I don’t mean heroine or cocaine. Legal prescription opioids, pain pills such as hydrocodone, are involved in more drug poisoning deaths than illegal drugs.
The National Center for Health Statistics (NCHS) reports that 9 out of 10 poisoning deaths are caused by drugs. And since 2009 more people have died as a result of all types of drug poisoning, whether accidental or intentional, than car accidents.
We usually associate poisoning with children, but the largest increase in poisonings has been in the 20-59 year old age range, again related to … Continue reading
CT scans increase a child’s risk of developing cancer
A year ago the British medical journal, The Lancet, published a study looking at the potential cancer risk to children from using CT scans.
CT scans use ionizing radiation, and children are considered more “radiosensitive” than adults.
The Lancet study concluded there was “… a positive association between radiation dose from CT scans and leukaemia” and recommended “…although clinical benefits should outweigh the small absolute risks, radiation doses from CT scans ought to be kept as low as possible and alternative procedures, which do not involve ionising radiation, should be … Continue reading
My belief as a frugal nurse is that each of us has the power to improve our health and lower our health care costs. Prevention is key, and in my posts I advocate such preventive actions as vaccinations, hand washing, adequate sleep, drug safety, exercise and a healthy diet.
Diet is an important part of a healthy lifestyle and, I think, is crucial to cancer prevention.
Therefore, I read with keen interest a recent post by David Katz, MD, on the HuffPost Healthy Living Blog.
Dr. Katz interviewed a one-time student, Nicole Larizza, a nutritionist currently … Continue reading
