You know, after Tamara's recent succcess with the demodex slaying Z cream,
and others speaking of theirs with the red LED lamps, it would be an
interesting experiment to put some of the lil' buggers under red LED light
for awhile and see what happens to them... decrease in vitality or life
span, effects on reproduction, etc. etc.

If it did negatively impact them in someway, it would certainly be another
significant indicator for demodex as a root cause in rosacea.
Unfortunately, I do not as yet possess an LED array nor a microscope. Not
even a petri dish, lol. So someone else would have to conduct it.

Fry you little bastards, fry!!! ; D

"Intense pulsed light appears to kill Demodex mites around hair follicles and
sebaceous
glands.... Dr. Sadick of Cornell University, New York, conducted an
investigation in which
24 patients with a mean age of 47 years and Fitzpatrick skin types I-IV were
treated with
an intense pulsed light device (Quantum SR, ESC-Lumenis, Palo Alto, Calif.),
which emits a
noncoherent, multiwavelength of light of 500-1,100 nm. All patients were treated
monthly, up to five times, using an average fluence of 25-45 J/cm2....

"If you treat patients with intense pulsed light, you can eradicate almost all
the
organisms," he said.

The findings help explain the results already observed with intense pulsed
light, Dr. Sadick
said. They also suggest that the patient who will benefit most is the person in
his or her
mid-40s who wants to reverse early sun damage but does not need dramatic rhytid
improvement.

...Killing of the Demodex organisms, and consequently toning down inflammatory
processes, probably explains why intense pulsed light improves redness. Many
patients
believe that they have a decrease in pore size, and this may be due to shrinkage
of the
sebaceous glands. Normalization of the elastin fibers may improve elasticity and
account
for some of the smoothing of texture that is seen. Decreased melanin production
accounts
for the improvements in dyschromia...."

The possibility of RLT killing Demodex has crossed my mind, too. Would
be easy to look at someone's skin after several months of RLT use to
compare. Maybe Peter's skin is squeaky clear of Demodex. Maybe killing
Demodex is just one benefit along with the anti-inflammatory and
collagen effects. Lots of maybe's, but very interesting to
contemplate!

Quick, someone grab Peter and a microscope ;)

Brian, This is indeed a definite possibility as it has been known for a while
that Blue Light can kill Propionibacterium Acnes. (P.Acnes).

Blue light is FDA approved for killing P.Acnes.

Apparently it was initially discovered when some scientists were trying to count
the number of ¡bugs¢ on surface tissue. The bugs fluoresced when illuminated
with the blue light. This was due to the reaction with porphyrin which the bugs
used as part of its respiratory chain, the fluorescing was the porphyrin
producing oxygen, the bugs did not like too much oxygen and consequently die.

There are many support articles for the destruction of P.Acnes with LED light.

http://www.medscape.com/viewarticle/499713_2

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=Abstra\
ctPlus&list_uids=17111415&query_hl=9&itool=pubmed_docsum

ctPlus&list_uids=16766484&query_hl=9&itool=pubmed_DocSum


Blue has been proven to be the most affective for killing the P.Acne, but it has
also been noted that Red Light also kills P.Acne, and can penetrate deeper into
the skin, destroying P.Acnes that the blue light cannot reach. The two studies
shown above list combination treatments with Blue and Red.

I did some quick googling but couldn¢t find what the demodex mite uses for its
respiratory chain. But it is possible that it has the same affect.

Did a little more research. Unfortunately without more background knowledge it’s
only speculation, but seems to be heading somewhere.

There is a gram negative bacteria found within the Demodex Mite called Bacillus
Oleronius.


The following is an article on LLLT and Gram Negative Bacteria. It mentions two
other types of Bacteria, being the Gram Negative Pseudomonas aeruginosa and the
Gram Positive Staphylococcus aureus.

They classify the difference as follows. Gram-negative bacteria are those that
do not retain crystal violet dye in the Gram staining protocol. Gram-positive
bacteria will retain the dark blue dye after an alcohol wash, whereas
Gram-negative bacteria do not. In a Gram stain test, a counterstain is added
after the crystal violet, which colors all Gram-negative bacteria a red or pink
color. The test itself is useful in classifying two distinctly different types
of bacteria based on structural differences in their cell walls.

Here is a quote…

“All energy densities of Ar ion laser showed a proliferative effect on
Pseudomonas aeruginosa and inhibitory effect on Staphylococcus aureus.
Similarly, SHG Nd:YAG and He-Ne lasers with chosen energy densities were again
proliferating for Pseudomonas aeruginosa and inhibitory for Staphylococcus
aureus“

http://www.springerlink.com/content/e072158g52487462/

This shows that LLLT definitely has an affect on Gram-Negative/Positive
bacteria.

Unfortunately you have to purcahse the article to see it in its entirety. If you
look at the google search though it mentions something about Gram negative
Bacteria with higher amounts of porphyrins, so it gives a teaser to possibly
releasing some information there.

http://www.google.com.au/search?hl=en&q=gram-negative+bacteria+respiratory+chain\
+porphyrin&meta=



This article mentions Bacillus, Porphyrin and respiratory chain but there was
soo much medical jargon it was hard to put it all together. Maybe Dan could
decipher this one for us if he has a spare minute?

http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=197023


This article from the Rosacea Archives relates a possible cause to Bacillus
Oleronius also.

http://www.rosacea.org/press/archive/20040503.php

Hmm, All I can add is that LLLT definitely has an affect on bacteria. But for
Bacillus Oleronius specifically though, I am unsure.

Matt.

Hi Matt,

Thanks for your contribution to the discussion on this topic, which was of
course rather more detailed than the snippet above. ;)

I wonder if anyone else might like to take up the challenge and locate a study
with this information? You never know, someone might have a bit of time on their
hands and want to demonstrate their superior abilities with search engines. No
harm in cautious optimism, is there? :)

Kind regards,

Aurelia

Hi Matt,

Thanks for posting this info. I found it very interesting,
particularly since most articles I've read haven't mentioned naturally
occuring porphyrins in bacteria, but rather concentrate on application
of additional porphyric substances in addition to light therapy.

I couldn't dig up too much more that helped explain this, but here's
an article discussing light therapy (mostly laser, but again, I don't
think the light source is all that important here) and porphyrins.
It explains pretty well how they work together, namely, "Light energy
is absorbed by bacterial porphyrins, triggering production of toxic
singlet oxygen which damages or destroys the bacteria":

http://www.shorelaser.com/LaserAcneRx.html

So with your articles and other suggesting that certain bacterial seem
to have naturally occuring porphyrins, potentially light therapy can
be antibacterial for these bacteria even without the use of additional
photoactive substances (like ALA, etc).

Along these lines, the only thing that worries me is the statement
"all energy densities of Ar ion laser showed a proliferative effect on
Pseudomonas aeruginosa".

Does this sort of answer your questions? If not, let me know and
I'll take another stab at answering...

Thanks again...

Dan

See the below study, which indicates Demodex is the carrier. I thought this
excerpt was pretty interesting: "typical treatment for rosacea
initially includes oral antibiotics that destroy B. oleronius.
Interestingly, he said, antibiotics that are not harmful to these
bacteria generally are not effective in the management of rosacea. "
-Artist


The role of bacterial antigen(s) in the etiology and persistence of
papulopustular bacteria.
Dr. Kevin Kavanagh, Department of Biology, National University of
Ireland - Maynooth, and Dr. Frank Powell, consultant dermatologist,
Mater Misericordiae Hospital, Dublin.

Bacteria associated with microscopic mites known as Demodex
folliculorum may play a role in the development of papulopustular
(subtype 2) rosacea, according to the results of a study funded by a
National Rosacea Society grant and reported at the 2004 annual meeting
of the Society for Investigative Dermatology.

In the completed study, Dr. Kevin Kavanagh and colleagues found that
the bacterium Bacillus oleronius stimulated an immune system response,
inducing high levels of T-cell proliferation, in 79 percent of
patients with subtype 2 rosacea, compared with only 29 percent of
patients without the disorder. T-cell proliferation induces an
inflammatory response, evident as papules and pustules.

"This indicates that the Bacillus bacteria found in the Demodex mite
produce an antigen that could be responsible for the tissue
inflammation associated with papulopustular rosacea," Dr. Kavanagh
said.

The researchers located the bacteria in Demodex folliculorum, which
are normal inhabitants of human skin. Because these microorganisms
often occur in much greater numbers in patients with rosacea,
researchers have long theorized that they may play a part in the
development of the disorder.

The researchers offered several possibilities that may explain how
Demodex and bacteria interact to cause inflammation in rosacea. The
Demodex mites may carry the pathogenic bacteria into areas of the face
susceptible to the changes of rosacea, so that the increased mite
density in rosacea patients may result in a higher density of bacteria
that produce the papules and pustules. Alternatively, Demodex mites
may be attracted to an area of facial skin rich in these bacteria and
increase in numbers in this "fertile territory."

Another possibility is that the mites in rosacea patients are infected
with these bacteria, which in turn produce stimulatory antigens that
trigger the disorder in susceptible patients.

Dr. Kavanagh noted that the potential role for bacteria in causing
papulopustular rosacea is supported by the fact that typical treatment
for rosacea initially includes oral antibiotics that destroy B.
oleronius. Interestingly, he said, antibiotics that are not harmful to
these bacteria generally are not effective in the management of
rosacea.

Moreover, the possibility that antigens may play a role in disease
processes has been demonstrated in other disorders. For example,
antigens produced by Streptococcus and Staphylococcus bacteria have
been linked with such disorders as psoriasis, food poisoning and toxic
shock syndrome.

Dr. Kavanagh and his colleagues are now developing antibodies against
the antigen produced by B. oleronius to confirm its presence on the
faces of patients with papulopustular rosacea and to define its
relationship with Demodex mites.

When first researching Rosacea I also ran across this fact - I read
that only antibiotics that worked against gram negative bacteria were
helpful for rosacea - reason unknown.

Hi Dan,

Yeah that confirms a few things.

When i was trying to find whether B.Oleronius contained naturally occuring
Porphyrins, I couldn't find any matches, so did a quick search to find if other
Negative Gram bacteria contained Porphyrins, but it seems to vary.

I think it is established that the production of singlet oxygen produced by the
light reacting with the porphyrin is destructive to the bacteria, However I
cannot locate if porphyrin is naturally occuring in B.Oleronius. Any ideas
there?

Yeah i share your concern about the statement that had the words "Proliferative"
and "Pseudomonas aeruginosa" in the same sentence. With consideration to the
fact that it is apparently an opportunistic bacteria that thrives in burns,
wounds and cuts.

One of the major marketed uses of LED therapy is for wound healing. If it could
possibly have a proliferative affect on some form of gram negative bacteria this
could be a problem.

Hi Matt,

Thanks for posting this info. I found it very interesting,
particularly since most articles I've read haven't mentioned naturally
occuring porphyrins in bacteria, but rather concentrate on application
of additional porphyric substances in addition to light therapy.

I couldn't dig up too much more that helped explain this, but here's
an article discussing light therapy (mostly laser, but again, I don't
think the light source is all that important here) and porphyrins.
It explains pretty well how they work together, namely, "Light energy
is absorbed by bacterial porphyrins, triggering production of toxic
singlet oxygen which damages or destroys the bacteria":

http://www.shorelas er.com/LaserAcne Rx.html

So with your articles and other suggesting that certain bacterial seem
to have naturally occuring porphyrins, potentially light therapy can
be antibacterial for these bacteria even without the use of additional
photoactive substances (like ALA, etc).

Along these lines, the only thing that worries me is the statement
"all energy densities of Ar ion laser showed a proliferative effect on
Pseudomonas aeruginosa".

Does this sort of answer your questions? If not, let me know and
I'll take another stab at answering...

Thanks again...

Dan

Hi Matt,

I did some searching, but couldn't find anything on B.Oleronius and
porphyrins either. I also did a search on the species and porphyrins
but did not find anything that would indicate that all members of the
species would contain porphyrins...

Ewwww Dan that's gross! Hmmm....maybe if I put peanut butter on them..
and honey.. ha ha!

All the demodex and B.Oleronius talk is very interesting. Exciting to
see new ponderings.

Haha. I wish that were the case Artist. Maybe we can just breed something
specifically for the job. I'm sure you could take a pick from one of your many
options growing in my bar fridge on the balcony! Surely if you had a million
diffferent options one of them would have to do the job!

Dan, I couldn't find any detailed information either on B.Oleronius either. I
tried to search for the the general Genus 'Bacillus' - but couldn't find any
good information either. Might need to go to some text books for this one. I
then starting thinking about the probitoics containing Lactobacillus that I
generally have once a day. Apparently 'bacillus' can be used to describe any
rod-shaped bacterium, however, when the word Bacillus is capitalised and
italicized, it refers to the genus bacillus. (thanks for the clear
classifications Mr scientists! real handy!) So silly me has no reason to worry
about dangerous inflammatory lipase enzymes in lactobacillus which are found on
B.Oleronius

Matt.
