Superabsorbent charcoal dressing versus silver foam dressing in wound area reduction: a randomised controlled trial.

AIM: This study aimed to compare the effect of a novel sterile polyacrylate wound pad with activated carbon cloth treatment with a standard non-adhesive hydrocellular foam dressing with silver in reducing wound area. METHOD: A multicentre randomised controlled open-label wound-dressing trial was conducted in two wound care outpatient clinics in western Switzerland from November 2018 to March 2020. RESULTS: A total of 77 successive patients were randomised to receive either a sterile polyacrylate wound pad with activated carbon cloth treatment (n=38) or the standard non-adhesive hydrocellular foam dressing with silver (n=39). Reduction in wound area was the primary outcome, whereas the application period of the dressing, odour, maceration and pain were the secondary outcomes. Wound area was measured at baseline and during each wound dressing change until the dressings were no longer indicated. Wound area reduced faster in the intervention group than in the control group (0.45cm2 per day vs. 0.2cm2 per day), although the application period was longer in the intervention group compared with the control group (9.5 days vs. 8.1 days). Maceration reduction was more pronounced in the intervention group (-2.07cm2) than in the control group (-0.71cm2). Odour, pain and infection were similar in both groups. CONCLUSION: Sterile polyacrylate wound pad dressings with activated carbon cloth reduced the wound area, as well as the maceration area, faster than the non-adhesive hydrocellular foam dressing with silver.

[Honey: from Noe to wound care]. / Le miel: de Noé aux soins de plaies.

Honey with its high concentration of sugar constitute a hyperosmotic medium with antimicrobial properties. It contains different enzymes, including glucose-oxidase that generates hydrogen peroxide and gluconic acid in the presence of glucose and water. The viscosity and the hygroscopic qualities of honey permits its even spread on the wound bed, creating a favourable environment for wound healing. With these properties, honey when adequately prepared, is an efficient treatment of chronic wounds of the lower leg and also of abdominal wounds.

General consumer communication tools for improved image management and communication in medicine.

We elected to explore new technologies emerging on the general consumer market that can improve and facilitate image and data communication in medical and clinical environment. These new technologies developed for communication and storage of data can improve the user convenience and facilitate the communication and transport of images and related data beyond the usual limits and restrictions of a traditional picture archiving and communication systems (PACS) network. We specifically tested and implemented three new technologies provided on Apple computer platforms. (1) We adopted the iPod, a MP3 portable player with a hard disk storage, to easily and quickly move large number of DICOM images. (2) We adopted iChat, a videoconference and instant-messaging software, to transmit DICOM images in real time to a distant computer for conferencing teleradiology. (3) Finally, we developed a direct secure interface to use the iDisk service, a file-sharing service based on the WebDAV technology, to send and share DICOM files between distant computers. These three technologies were integrated in a new open-source image navigation and display software called OsiriX allowing for manipulation and communication of multimodality and multidimensional DICOM image data sets. This software is freely available as an open-source project at http://homepage.mac.com/rossetantoine/OsiriX. Our experience showed that the implementation of these technologies allowed us to significantly enhance the existing PACS with valuable new features without any additional investment or the need for complex extensions of our infrastructure. The added features such as teleradiology, secure and convenient image and data communication, and the use of external data storage services open the gate to a much broader extension of our imaging infrastructure to the outside world.
