Eyespy brings you the latest quirky medical
stories from around the world
Could birthdays predispose people to stroke
and heart attacks? Apparently, the answer is yes. This frightening
conclusion comes from a Canadian study that found more people were
admitted to emergency departments on their birthday as a result of
vascular events compared with the control conditions of asthma and
appendicitis. The association was stronger if predisposing
conditions such as hypertension were present (Neurology 2006 May 25; doi:
10.1212/01.wnl.0000217915.06 544.aa).

After last month's article on e-leaning,
Eyespy was surprised to hear that doctors often show resistance to
new technology, especially computer systems. Case study analyses of
the implementation of computer information systems in three
hospitals showed that the “implementers” themselves
played an important part in whether the outcome was successful (CMAJ 2006;174:
1573-8). Implementation was successful when the implementers dealt
with the real reasons underlying this resistance. Implementation
failed when they didn't respond to resistance behaviour,
offered antagonistic responses, or when support was aimed at the
wrong object of resistance.
Summer is here, and Eyespy knows the best
advice is to stay out of the sun, cover up, and use sunscreen
lotions. But researchers have recently found that repeated exposure
to such lotions can increase the levels of serum thyroid
stimulating hormone in rats. In addition, the weight of the thyroid
gland was also found to be increased. Should we put off the use of
sunscreens then? Not yet, say researchers (http://news.bbc.co.uk).
Some people doubt the existence of a clinical
entity defined by an overt addiction to videogames, but a company
based in Amsterdam is all set to launch a rehabilitation programme
for young cyberaddicts. It has been well known that authorities in
countries such as South Korea, China, and the United States have
become increasingly concerned about young people spending too much
time in front of their computers. The Dutch rehabilitation
programme is the first of its kind in Europe, aimed at parents
worried about their children spending all their energy on video
games (www.independent.co.uk).
Tick tock, tick tock. It's time to go to
bed, your adrenal glands say. And that's what scientists from
Oregon have just found—genes linked with the circadian cycle
were rhythmically expressed in rhesus monkeys' adrenal
glands. The suprachiasmatic nucleus was once thought to be the only
part involved with body clock mechanisms, but that might not be the
final word. The scientistss have identified 322 transcripts with
rhythmic patterns of expression and most of them show activation at
night (Molecular Endocrinology 2006;20:1164-76).
Pakistanis are concerned with penis
enlargement and bird flu, whereas Indians want information about
condoms and metatarsals. South Africans concentrate on malaria and
AIDS, and Singaporeans want to know about body odour and slimming.
In Ireland, loneliness and facial hair top the bill, and in the
United Kingdom they search for information about chips and chicken
tikka masala. Google Trends, which reports which nations conduct
the most internet searches for particular items, offers up cultural
insights (Independent 2006 May 17).
Many hospital patients are confused about
whether to call their doctor “Doctor” or
“Mister” (or “Miss”). Just when they start
to get the hang of it, they're caught out again. Now they
have physicians, dressed like surgeons, sticking a cardiac stent in
them—and wanting to be called doctor. And the stent insertion
is an intervention, rather than an operation, because it's
not carried out by a card carrying surgeon. In the US, of course,
“Doctor” will do for every vet, dentist, osteopath, and
podiatrist (Journal of the Royal
Society of Medicine 2006;99:
164-5).
Eyespy is concerned for your health during the
World Cup. There's so much to celebrate, but watch out. A
report by the Liberal Democrats party stated that Britons will
consume an extra 218 billion calories during the tournament. Added
to that, the British Beer and Pub Association reported that
England's supporters will drink an extra 80 million pints of
beer and lager, in supporting the team all the way to the final
(www.timesonline.co.uk).
Given the choice between waiting to receive an
electric shock and getting it over with as quickly as possible,
some people choose to have a stronger shock rather than wait for a
mild shock. Not surprising, say the scientists who used functional
magnetic resonance imaging to study neural responses to cutaneous
shock. The levels of dread correlated well with the increase in
neural activity in the posterior elements of the pain matrix and
were a result of anticipating the adverse event, rather than of
simple fear or anxiety (Science 2006;312:754-8).
Not getting enough sleep is a risk factor for
high blood pressure, according to an analysis of the first national
health and nutrition examination survey in the US (Hypertension 2006;47:
833-9). Sleeping less than five hours a night was associated with
a significantly increased risk of hypertension in people aged
between 32 and 59, a relation only partially attenuated by
adjustment for potential confounding factors such as obesity and
diabetes.
Ozone pollution chokes not just our cities,
but could choke our arteries as well. It has been known for some
time that ozone reacts with cholesterol and produces substances
called atheronals. These atheronals have been found in
atherosclerotic plaques. Researchers have now found evidence that
atheronals (and hence ozone) play an important role in
atherogenesis itself, by activation of monocytes into macrophages.
The inflammatory reactions thus induced have an important role in
the formation of the fibrofatty plaques that cause narrowing of
arterial walls (www.newscientist.com).
