Unique combination of hyaluronic acid and amino acids in the management of patients with a wide range of moderate-to-severe chronic wounds: Evidence from international clinical practice.

The availability of new products and strategies to manage wounds has taken a quantum leap in recent years. Healthcare professionals now have an extensive range of products to choose from, but while positive this also raises dilemmas in real-world clinical practice to decide on the most appropriate treatment for a given patient. Clinical trials confirm the effectiveness of the unique combination of hyaluronic acid and amino acids (Vulnamin®) in a range of wounds, but are these results replicated in real-world clinical practice? International experts presented their clinical experience with the use of the combination in difficult-to-treat wounds.

Preparation and characterization of a novel skin substitute.

Autologous epidermal cell cultures (CEA) represent a possibility to treat extensive burn lesions, since they allow a significative surface expansion which cannot be achieved with other surgical techniques based on autologous grafting. Moreover currently available CEA preparations are difficult to handle and their take rate is unpredictable. This study aimed at producing and evaluating a new cutaneous biosubstitute made up of alloplastic acellular glycerolized dermis (AAGD) and CEA to overcome these difficulties.

Accuracy of 18F-FDG-PET/CT for staging of oral squamous cell carcinoma.

Background: This study prospectively assessed 2-[F18]-fluoro-2-deoxy-D-glucose-positron emission tomography (18F-FDG-PET)/CT (PET/CT) in oral squamous cell carcinoma.

Methods: Twenty-three patients completed preoperative TNM staging (CT, MR, whole-body fusion imaging PET/CT). In patients who underwent surgical therapy (19 of 23), TNM staging based on PET/CT scan was compared with pTNM.

In vitro mechanical compression induces apoptosis and regulates cytokines release in hypertrophic scars.

Hypertrophic scars resulting from severe burns are usually treated by continuous elastic compression. Although pressure therapy reaches success rates of 60-85% its mechanisms of action are still poorly understood. In this study, apoptosis induction and release of interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) were evaluated in normal (n = 3) and hypertrophic (=7) scars from burns after in vitro mechanical compression.

Release and activation of matrix metalloproteinase-9 during in vitro mechanical compression in hypertrophic scars.

Objective: To investigate induction of matrix metalloproteinases (MMPs) during mechanical compression of hypertrophic scars. Mechanical pressure blocks hypertrophy inducted on extracellular matrix in scars by a mechanism that involves MMP-2 (gelatinase A) and MMP-9 (gelatinase B).

Design: We assayed conditioned media obtained from normotrophic and hypertrophic scars during 24 hours of in vitro mechanical compression using gelatin zymography.
