News in Brief
Small
pressure controlled probe for the
MoistureMeter SC
to measure skin surface hydration
 Delfin
has
developed a new, smaller probe for the
MoistureMeter SC. The small probe is equipped with a contact pressure
control to ensure repeatable, user-independent skin surface moisture
measurements.
The contact diameter of the new probe is only 10
mm making it even more user-friendly on the face and small areas.
The small
probe is included in the new MoistureMeter SC package together with the
standard probe.
If you already have the MoistureMeter SC and want to configure it to be
compatible with the small
probe, please send us an email

Handy Carrying Cases now
available
New
durable plastic Carrying Cases are now
available for all Delfin
instruments. The cases are filled with strong polyethene giving
perfect protection while carrying
and
storing the instruments.
All new instrument orders
include Carrying Cases. If you wish to
purchase a Carrying Case for your existing instruments,
please email us here.
VapoMeter featured on BBC
The
Delfn VapoMeter used for TEWL measurements was recently featured in BBC
Two's Horizon science program in the UK. The program "Prof Regan's
Beauty Parlour" hosted by Professor Regan concentrated on the claims
and the research of cosmetic products. The VapoMeter was shown in use
at the Boots R&D facility in Nottingham.
Daniel
Whitby from Alliance Boots comments:
 "Boots
bought their first VapoMeter in 2004 after
testing various other
devices. The VapoMeter was selected for its stability of readings, ease
of
use and the very user friendly software which is supplied with it. It
has
proved to be a very popular device in the unit, so much so that we have
recently purchased a second VapoMeter. Customer service from Delfin has
also been excellent and I recommend the device highly."

Delfin at SAWC 2007
in Tampa
Delfin Technologies participated as an exhibitor at the annual
Symposium on Advanced Wound Care (SAWC) that was held this year in the
warmth of Tampa, FL. The areas of interest that delegates showed
towards Delfin's instruments related to their use in research areas
including lymphedema, burns, and specific wound and compression
dressings. It appears that there is increasing interest in using
validated instruments in wound care research to achieve more reliable
and accurate data especially when edema needs to be assessed.
Delfin sponsored the ASCS 2007
Delfin Technologies participated as a sponsor at the Asian Society of
Cosmetic Scientists conference held in Singapore 7-9 March, 2007. The
conference brought together a large number of delegates who benefitted
from
scientific and industry presentations, workshops and networking
possibilities. Delfin's Director of International Marketing and Sales,
Mr.
Aki Immonen, contributed to the conference program by giving an
industry
presentation titled "The Art of Practical and Reliable TEWL and Skin
Hydration Measurements".
Dr.
Harvey N. Mayrovitz awarded at SAWC 2006
Dr. Harvey N. Mayrovitz from Nova Southeastern University, Ft.
Lauderdale, Florida was awarded a
Certificate of Achievement,
Oral Presentation, First Place at The Symposium on Advanced Wound Care
in San Antonio, Texas, 2006.
He utilized the Delfin MoistureMeter D in his study and the talk he
gave
was titled
"Assessment of local tissue edema in arms of women with postmastectomy
lymphedema".
Dr. Mayrovitz comments:
 "I have had the opportunity to use the Delfin
MoistureMeter D in conjunction with several research studies
investigating the characteristics and changes in tissue edema and
lymphedema. I am impressed by the systems simplicity of use and the
repeatability of sequential measurement data that it provides. Beyond
this, perhaps its most useful feature is its unique ability to assess
local tissue edema or lymphedema at virtually any body site.
New
studies, including the use of this system as a means of early detection
of incipient lymphedema, are now underway."
Recent publications
Skin barrier recovery in mice
proven by the Vapometer
Authors Amano et al from Pharmaceutical Research Center, Kyowa Hakko
Kogyo Co., Ltd in Japan utilized Delfin VapoMeter to show a recovery of
skin barrier in mice. The skin barrier was disrupted by tape stripping
and the VapoMeter TEWL instrument was used to follow-up the olopatadine
induced recovery of the barrier. The study was published in latest
British
Journal of Dermatology (156, 906-912, 2007).
Skin
tissue water during a menstrual cycle
Dr. Mayrovitz et al used Delfin’s water specific
MoistureMeter D instrument to see the effect of menstrual cycle on
local
tissue water content. Ten premenopausal women were measured three times
during their cycle at 4, 12 and 22 days after the start of their
menses. The results showed no significant cycle-dependent variations in
tissue water volume. The authors conclude that the contralateral arm
provides a control site in paired arm studies at any time point in the
menstrual cycle. The study was published in Clinical
Physiology and Functional Imaging (27, 54-59, 2007). (Free

Evaluation of hyperhidrosis with
the VapoMeter
Rieger and Pedevilla from Austria used the Delfin
VapoMeter to determine the effectiveness of sympathectomy for
preventing plantar hyperhidrosis. Perspiration of the sole was measured
on pre- and post-operative days. A clear reduction of sweat secretion
was found. The study was published in Surgical
Endoscopy last
month ( 21: 129-135, 2007).
Measurement of irritant-exposed
skin edema
We used the MoistureMeter D to assess sodium lauryl sulphate (SLS)
induced skin edema. After 6
hours occlusion of 1%
SLS the water-specific measuring values were up to 1.45 times higher
than at baseline. Another group was treated using
topical medium-strong corticosteroid that almost completely prevented
SLS-induced skin edema. These findings were published at the end of
last year
in Skin
Research and Technology (November: 235-240, 2006).
Depth
evaluation of thermal burns
The Delfin MoistureMeter D was used to measure local edema and to
evaluate depth of thermal burn. In clinical
practice early burn depth determination can lead to early excision
and grafting when needed. An established skin burn model using pigs was
adopted to show that partial and full thickness burns could be
differentiated at 8 hours post burn. The study was published
in Plastic
and Reconstructive Surgery last year (March: 899-901, 2006).
