Randomized Controlled Trial Multicenter Study Comparative Study
A prospective, multi-centre, randomised, open label, parallel, comparative study to evaluate effects of AQUACEL® Ag and Urgotul® Silver dressing on healing of chronic venous leg ulcers.
This study compared wound healing efficacy of two silver dressings, AQUACEL(®) Ag and Urgotul(®) Silver, against venous ulcers at risk of infection, over 8 weeks of treatment. The primary objective was to show non inferiority of AQUACEL(®) Ag to Urgotul(®) Silver. Patients (281) were randomised into two groups. ⋯ The non inferiority of the AQUACEL(®) Ag group to the Urgotul(®) Silver group was established based on the difference between them (6·84% ± 56·3%, 95% confidence interval -6·56 to 20·2) and the pre-defined non inferiority margin (-15%). Composite wound healing analysis showed that the AQUACEL(®) Ag group had statistically higher percentage of subjects with better wound progression (66·9% versus 51·9%, P = 0·0108). In general, both dressings were effective at promoting healing of venous ulcers.

Wound healing is a dynamic and complex biological process, which requires coordinated events including haemostasis, inflammation, proliferation, revascularisation and remodelling. Impaired wound healing is a common problem that occurs in both community and hospital settings. ⋯ Data derived from both animal and human studies showed that statins especially atorvastatin, simvastatin and pravastatin can accelerate the wound-healing process. However, further high-quality and evidence-based studies are needed to address the best statin drug, appropriate dose, the best administration route, duration of treatment and to determine correlation between pleiotropic effects of statins and their probable clinical benefits.

Comparative Study
Relationship between Braden scale score and pressure ulcer development in patients admitted in trauma intensive care unit.
The purpose of this study was to determine the relationship between the scores of Braden scale and pressure ulcer development among critically ill patients. All patients who admitted to intensive care unit (ICU) in 3 months (during July-October 2010) were surveyed with Braden scale. ⋯ Braden scale is a useful tool for predicting pressure ulcer development in trauma ICU patients. Also, factors such as age and level of consciousness may influence pressure ulcer development.

Randomized Controlled Trial Comparative Study
Split-thickness skin graft donor site management: a randomized controlled trial comparing polyurethane with calcium alginate dressings.
Split-thickness skin grafting (SSG) is a common reconstructive technique for the treatment of patients with deep burns and other traumatic injuries. The management of the donor site after harvesting an SSG remains controversial because of a variety of dressings available for use. The aim of this randomized controlled trial was to compare the effectiveness of a polyurethane dressing, Allevyn™, to a calcium alginate, Kaltostat®. ⋯ There were no significant differences between the two treatment groups with respect to time to wound healing, level of pain intensity, length of stay, staff and patient satisfaction levels. This trial showed Allevyn™ to be associated with increase demands on nursing time, increased cost of dressing products, medical consumables and wastes. Kaltostat® remains the dressing of choice for initial donor site dressing in this burns unit.

Comparative Study
Efficacy of hydrosurgical debridement and nanocrystalline silver dressings for infection prevention in type II and III open injuries.
The aim of this study was to retrospectively evaluate the clinical and culture-positive infection rates of open Gustilo/Anderson type II and III fractures using a protocol nanocrystalline silver wound dressing and hydrosurgical debridement. Retrospective case series through chart review on all type II and III open fractures were treated using a novel protocol from December 2005 to March 2008 (N = 17). All Gustilo/Anderson grade II and III open fractures were treated with a novel protocol at a Level I trauma centre. ⋯ There were no infections in the more high-energy Gustilo/Anderson grade IIIA and IIIB fractures compared with the Gustilo/Anderson control of 4-42%. We conclude that this novel protocol for open-fracture treatment is a promising intervention. A further prospective randomised clinical study is warranted.
