Spray-on therapy shows promise for leg ulcers
In a recent study, published in The Lancet, a new spray-on therapy made from donated skin cells has shown to be effective in healing leg ulcers without the need for tissue engineering. Made from growth-
arrested allogeneic neonatal keratinocytes and fibroblasts, the spray was used in different concentrations on outpatients with leg ulcers in 28 different health centres in the US and Canada. There was significant wound area reduction in the three groups that had the spray applied to their wounds, compared with those who were in the control group. The three groups contained
about 45 patients in each and had different dosing instructions for the spray. Those who showed the largest improvement overall were treated with the spray every 14 days. Adverse side-effects included new skin ulcers and cellulitis in more than 5% of patients in all groups. Click here for more information.
Free prosthesis trial for Paralympic-inspired amputees
Amputees who express an interest in taking up sport after watching the Paralympic Games will have the opportunity to trial a new prosthetic knee specifically developed for participating in athletics. Otto Bock Healthcare, the
official technical service provider for the 2012 Paralympic Games, has offered to loan out the new S380 prosthetic knee to encourage amputees who would like to partake in sports. Otto Bock intends to work with individuals and their physiotherapists to ensure the technology is fitted and used properly. 'People who see the
Paralympics and think "I want to try running", will have a chance to see if they like the limb before they potentially end up with a white elephant in the corner of their living room,' announced John McFall, an amputee who competed for Team GB at the Paralympics in
Beijing 2008. 'How many people joined a gym in January and have rarely gone back because it was not right for them? This is an opportunity for people.' Click here for more information

A new electronic suture technology can sense infections by measuring wound temperature. Researchers at the University of
Illinois, USA, have developed ultra- thin electronic sensors, which when embedded in small threads of silicon can be used as suture material for wounds. The sutures are made from
becomes infected, the temperature inside it rises, so the sutures alert clinicians if there is an underlying infection. The next
step, according to John Rogers, professor of materials science and engineering at University of Illinois, is to create sutures that are drug- infused and can be activated on command. Click here for more

New app documents and shares wound care cases
A new app for the iPhone and
iPad allows clinicians to document wound progress while they are on the go, using a patient logging system, photographs and social media sharing. Clinicians can now log wound
care progress through the WoundSmart® app documenting photos, patient information and significant wound history, as well as wound specific lab tests and cultures. The app can forward cases to colleagues and consultants, as well as 'sync' the cases into their electronic medical record system. There is also an option to share
specific photos and information on social networks for second opinions and feedback. Click here for more information.
