Older
Skin Needs More Sunscreen, Extra Protection,
Say Dermatologists

Marburg: Whether gardening at
home or vacationing at a beach resort, older
people need to be aware that exposure to the
sun without some kind of UV (Ultraviolet
Ray) protection is a danger.
“Seniors should use the same kind of
sunscreen as children,” advises Alexandra
Renkawitz of the German Green Cross, a
consumer health organisation. The extra
protection is needed because older skin is
particularly sensitive to sunlight.
“As you age, cell creation slows down. The
skin gets drier and more sensitive,” she
says. That also means older skin needs a
longer time to recover from sun damage. It’s
best to wear billowy, long-armed clothing,
plus a sun hat and sunscreen with UV
protection. These should all be part of an
older person’s standard summer attire. “And
instead of getting direct sun, sit in the
shade as often as possible,” advises
Renkawitz.
The elderly need to keep an eye out for the
effects of past sun damage, says Dirk
Eichelberg, a dermatologist in the German
town of Dortmund. Skin takes a long time to
recover from every sunburn. It can take 40
years for damage to become evident in some
cases. That’s why dermatologists assume that
the number of elderly suffering from common
skin cancers like basal cell carcinoma will
grow.
“We’re counting up to 200,000 new cases
every year. It’s growing explosively,” says
Eichelberg.
That’s why, the older one gets, the more
important it becomes to note changes in the
skin, adds Herberg Kirschech, a doctor of
dermatological diseases. Regardless of
whether the symptoms are reddening,
flakiness or a scab: “As soon as you see
anything unusual on your body, don’t delay.
Go to your doctor.”
“Apply sunscreen half an hour before you
leave the house,” he says. The sun
protection factor (SPF) should be as high as
possible. Older people with bald spots or
thinning hair need to protect the top of
their head with a hat or other head
covering. “Otherwise you run the risk of
dizziness,” warns Kirschech. Clothing also
offers some protection. “A white T-shirt has
an SPF of eight,” says Eichelberg. Renkawitz
recommends clothing with a thick knit and
dark colours. “Then the least amount of
sunlight gets through.”
Taking calcium or eating vegetables do not
help build up natural protection from
sunlight. “The effect is almost zero,” says
Kirschech. Special care also needs to be
taken when taking medications, warns
Renkawitz. “Some beta-blockers and
antibiotics can lead to sensitivity to
light.” |

A few
extra pounds can add years to your life:
study
http://www.ecanadanow.com/news/health/a-few-extra-pounds-can-add-years-to-life.html
Toronto (ECN) -
A Canadian study has shown that having a
little extra body weight might be good for
the body and actually a few extra pounds may
protect people from dying too early.
Researchers have discovered that obese and
underweight people are dying earlier than
those who are at a normal weight. And people
who are just a bit overweight are even
living longer than those at normal weight.
Researcher, David Feeny says it is not a
surprise to find that people who are very
underweight or very overweight increase
their risk of dying. It is a surprise,
thought, to know that carrying just a little
extra weight may provide longevity. Feeny
works and has studied these finding at the
Health Research Center for Kaiser
Permanente. Feeny’s fellow researcher, Mark
Kaplan, says that having a few extra pounds
may protect people as their health begins to
decline as they age, but wants to clarify
that it does not mean that people of normal
weight should try to add weight to their
body for this reason.
Kaplan explains that these findings were
found in a study that looked at mortality
and not the quality of life. There many
negative health results that can occur from
obesity, including high cholesterol, high
blood pressure and diabetes. This study was
based on the correlation between death among
11,326 adults living in Canada and their
body mass index. The data over a period of
12 years was taken from the National
Population Health Survey. |

Adult
Obesity On The Rise In Canada
http://lfpress.ca/newsstand/News/CanadaWorld/2009/06/26/9949761-sun.html
By CHRISTINA SPENCER, National Bureau
OTTAWA —
Obesity rates are going up, diabetes
is increasing and blood pressure problems
are worsening among Canadian adults.
To top it off, more people are having
trouble finding a family doctor — the
medical expert most likely to help prevent
such health conditions from occurring.
Statistics Canada’s latest Community Health
Survey shows that in 2008, more than 17% of
adults — or about 4.2 million people — were
obese. In the last five years, obesity rates
among men have grown from 16% to 18.3%.
Among women, they’ve bulged even further —
from 14.5% of the population to 16.2%.
Diabetes rates have also shot up, in just
three years, from 4.9% of the adult
population to 5.5%. And our blood pressure
is continuing to climb. In 2008, more than
16% of Canadians had high blood pressure, a
“significant increase” from 2005, according
to the survey. The data coincide with
findings that only 84.4% of adults have a
regular medical doctor, down from 85% five
years ago. The greatest gap showed in the
20-to-34 age group, where 34% of men had no
family physician.
Dr. Sarah Kredentser, president of the
College of Family Physicians of Canada, said
since young men are the healthiest
demographic, they don’t tend to see
themselves as needing preventative care. Yet
“it’s something we need to be concerned
about,” she said.
“We have lots of international research that
shows that health outcomes are better in
communities where everyone has a personal
family physician.” Kredentser said one of a
family doctor’s most important roles is
helping clients improve their health and
keep many kinds of illnesses from occurring
in the first place.
“If people don’t have access to that type of
service, then we’re going to continue to see
increasing rates of chronic diseases.”
The percentage of Canadians without a
regular doctor translates to between four
and five million people over the age of 18.
The community health survey does reveal some
positive trends. For instance:
n Exposure to second-hand smoke at home has
declined steadily in the last five years
from more than 10% to 7.4%;
n Almost 44% of Canadians eat fruit or
vegetables at least five times a day. In
2001, that number was only 37.6%;
n In 2008, 31.7% were vaccinated against
influenza, a result Kredentser said was
surprisingly good, given that not every
provincial health plan fully covers flu
shots.
Later this year, health authorities hope to
have an additional vaccination available for
the H1N1 swine flu virus.
“It’ll be interesting to see what happens,
whether H1N1 has an effect on personal
choices in regards to flu vaccines,”
Kredentser said. |

How Eating Less
Can Help Boost Lifespan
http://www.dnaindia.com/health/report_how-eating-less-can-help-boost-lifespan_1268414
Thursday, June 25, 2009
London: Scientists have long known that a
restricted diet extends life. Now,
researchers at the Salk Institute for
Biological Studies have identified two
enzymes that provide a new molecular
explanation for how eating less leads to
living longer.
Howard Hughes Medical Institute investigator
Andrew Dillin and colleagues identified two
proteins, WWP-1 and UBC-18, that link
dietary restriction to longevity in
roundworms.
Dillin says when researchers removed the two
enzymes from the test animals, the benefits
of a restricted diet disappeared.
And when those enzymes were enhanced,
longevity and disease resistance increased.
The scientists say understanding how these
molecules influence longevity could have
implications for developing new treatments
for age-related diseases.
"The only other known factor regulating
longevity in response to diet restriction
operates at the very end of the signaling
cascade," said Howard Hughes Medical
Investigator and senior author Andrew Dillin,
Ph.D., an associate professor in the
Molecular and Cell Biology Laboratory.
"These two enzymes are further up the
ladder, bringing us closer to the receptor
that receives the signal for throwing the
switch to promote a healthy lifespan,"
Dillin added.
The study has been published in the June 24,
2009, advance online edition of the journal
Nature. |

Warning: Never
Mix Javex With Any Other Cleaning
Compound!!!
Sent by Juliet Rebello
Local woman nearly killed after mixing
cleaners
EAMONN MAHER
A Terra Cotta woman who recently had a
near-fatal accident with household cleaning
agents wants to share her story with the
public in order to hopefully prevent a
similar incident from happening to someone
else.
Laura Fiander, 50, was cleaning the upstairs
bathroom of her rural residence near the
Terra Cotta Conservation Area around 2 p.m.
on July 8, while husband Mike Witt was
outside painting. A quiet day of doing
chores around the house soon turned into a
nightmare that nearly resulted in Fiander's
death and sent her to hospital for several
days.
"I had a shower and then I decided to clean
the tub afterward and I noticed some
hard-water deposits on the shower mat that
looked like mildew, and I dumped some Javex
in the tub and let the water run," said
Fiander, her voice still breaking from
damage to her larynx. "Then I noticed some
deposits on the shower curtain, so I got a
spray bottle with CLR and sprayed it. All of
a sudden there was a hissing sound and the
fumes overwhelmed me. It felt like a blow
torch was instantly going down my throat."
Fiander was able to make it to the front of
the house before collapsing to alert Witt to
the situation, but by this time she was
foaming at the mouth and gasping for air as
her oesophagus was swelling shut. The only
word she was able to blurt out was
"chemicals." After several minutes of trying
to resuscitate her, Witt called 911 when her
eyes and skin turned a ghostly blue colour.
"I kept hoping that with some fresh air she
might catch her breath, but she went into
convulsions, gagging intensely, and twice I
was able to revive her, but there was
nothing I could do. It was horrifying," he
said. "It's amazing she's still with us.
We're fortunate that an ambulance was just
10 minutes away in Caledon, and the two
female paramedics did a fantastic job."
After being stabilized at Georgetown
Hospital, Fiander would remain there for
another five days as doctors flushed the
toxins out of her body. Her lungs were
literally burned, and it may take several
years for them to return to normal, and she
has been basically confined to her home
because of the susceptibility of contracting
an illness or developing an infection.
Fiander uses a puffer six times a day to
help her collapsed lungs expand to their
former size and faces a lengthy recovery
period with several more trips to see
specialists.
"I'm not sure of the exact contents of the
CLR, but I'm guessing it contains ammonia,
and when that is mixed together with bleach
it gives off a noxious gas, a form of
chlorine gas," said Emmanuel Adianas, a
spokesperson for Colgate-Palmolive Products
Ltd. "We strongly recommend not to mix Javex
with any products, period...As far as I am
aware, this is not a common occurrence, but
it certainly can happen."
Witt, who operates a freight-forwarding
business out of the couple's home, would
like to see changes in the labelling of such
potentially deadly household cleaners that
would more effectively alert consumers of
their danger.
"I've spoken to literally hundreds of people
since this happened, and yes they do know of
the danger from these chemicals, but most
don't know it's fatal, and that should be
played up more in the packaging," he added.
"These things should be locked up in
cupboards like prescription drugs, or at
least have a better labelling system. There
needs to be better public awareness,
especially in households with children."
Fiander is also circulating a letter, which
tells her frightening story and warns of the
deadly dangers of household cleaners.
"I was told that this chlorine gas is
similar to mustard gas that was used in the
First World War," Fiander said. "My throat
literally closed up. What a horrid way to
die. Who would ever think that just a quick
whiff like that could kill you?" |

Calling All
White Blood Cells

Anyone who has felt the sting as hydrogen
peroxide foams and fizzes on a scraped knee
knows about the compound's antiseptic
properties. But new research suggests that
hydrogen peroxide does more than just kill
microbes. It may also call for
reinforcements, summoning an army of
bacteria-fighting cells to cuts and wounds.
Punctured skin sets off a chain reaction of
chemical signals that activates
blood-clotting and attracts an array of
immune cells to guard against intruding
microbes. Some of these cells, known as
leukocytes, or white blood cells, kill by
initiating a "respiratory burst," which
releases highly reactive antimicrobial
molecules, including hydrogen peroxide
produced by the body itself. |
