Heavy-metal dancers can get whiplash from head banging
The Associated Press
WASHINGTON — Rock music now has its own malady — "head banger's whirlwind."
And Dr. Marilyn Kassiter warns that, after the music ends, the malady lingers on.
The neurologist at Boston University School of Medicine concedes that she is no expert on youth culture. But she does know injuries. And she wrote up these in a case report in The Clinical Journal of Pain.
head勇挠 a whipstand develops when muscles that control movement of the head and neck are flexed and extended about as much as they can be, so the head and neck are rhythmically and repetitively rotated. Kaisser said
She found it among 37 Newton, Mass., eighth graders who took part in a five-to-seven hour dance marathon for charity. During three heavy metal songs, dancers got their beads moving with such force that many of them developed neck pain that lasted one to three days, the article said.
The doctor followed up by surveying the young dancers on the extent of their pain
Nine of the 11 girls and one of the six boys who danced to the heavy metal music reported pain, the article said. The association was not statistically significant for boys. But for girls, the link between dancing and pain was so strong that researchers would not consider it the result of chance.
the girls had long hair and whipped it in a circle as they danced, adding centrifugal force to the strain of the movement. Kassiter said.
The injuries had healed by the time Kassirer found out about them. The youngsters used common remedies such as aspirin and ibuprofen, the doctor said.
The injuries were self-limiting partly because they were self-induced, Kassirer said. In whiplish that results from impact, such as a car accident, the forces involved and the extent of the injuries are greater, she said.
Also, people under 16 have remarkably elastic ligaments, which also probably helped recovery, Kassirer's article said.
Head banger's whiplash appears to be a simple case of too much strain on muscles and ligaments, said Dr. Charles Anderson, associate coordinator of Primary Care Sports Medicine at Hennepin County Medical Center in Minneapolis.
Anderson also conceded that he is not up on all the latest dances. But he believes those dancers were stretching a bit more.
As long as they are not banging into each other or into objects, the young head bangers should do fine. Anderson said.
In any case, listeners will not stand still. Movement gets you into the music, said Daniel Fidler, an assistant editor of Spirz a youth culture magazine in New York.
“It’s kind of trippy, in a way,” Fidler said. “You get clated. You are throwing your body into the music. It’s like a joining thing.”
At a crowded dance or concert, throwing your head around is about all the movement there is room for. Filler said.
Adult leukemia linked to smoking
The Associated Press
ATLANTA — Smokers have a 50 percent greater risk of contracting a deadly form of adult leukemia, according to government research that presents the strongest link yet between cigarettes and leukemia.
Tobacco smoke causes 22 percent of all cases of myeloid leukemia, making it the leading known cause of the disease, the study by a national Centers for Disease Control and Prevention scientist found.
"A lot of people are worried about exposure to radiation and electromagnetic fields, which are linked to leukemia," the scientist, Dr. Michael Siegel, said Thursday. "But it's clear that smoking is much more deadly."
it's yet another cancer related to a known carcinogen, which is tobacco smoke," said Dr. Clark Heath of the American Cancer Society.
Leukemia is a cancer of the blood cells. The cancer society expects 26,700 new cases in U.S. adults this
year. About 12,000 of those will be myeloid leukemia, which is often fatal
Doctors do not know everything that causes myeloid leukemia, although the chemical benzene, radiation and certain viruses are known to cause some cases.
Since 1986, doctors have been looking for evidence that smoking also causes adult leukemia.
Now Siegel has gone a step further.
For just myeloid leukemia, he found that smokers have a 50 percent greater risk than non-smokers.
In February, the strongest evidence to date was reported in the Archives of Internal Medicine. Researchers found that smokers had a 30 percent higher risk for contracting adult leukemias and that tobacco smoke caused about 14 percent of all cases — or 3,600 a year.
Also, his analysis of 15 smoking- and cancer studies found that smoking caused more of that cancer than did all other known risks combined
"Because myeloid leukemia is often
fatal, if we could eliminate smoking,
we could eliminate 20 percent of adult
leukemia deaths," Siegel said.
There is biological evidence to back up his findings.
Tobacco smoke contains high levels of benzene, radioactive lead and radioactive potium, all of which are carcinogens.
■ Smokers have high levels of radioactive lead in their bones, which is where the blood cells that leukemia attacks are produced.
- Smoking suppresses the immune system, preventing it from fighting cancer cells.
Siegel urged more study to determine the effects of smoking on other forms of adult leukemia.
He did find some good news. The longer a former smoker had gone without a cigarette, the lower the person's risk of developing myeloid leukemia.
"So it's not too late to quit," Siegel said.
