Injury

Morel-Lavallee lesion is a closed degloving soft tissue injury in which subcutaneous tissue is torn from the underlying muscular fascia. The tear leads to venolymphatic leak, and concomitant adipose tissue necrosis from the force of the trauma causes swelling and possible infection at the site of injury. The traditional treatment for the lesion is surgical drainage and debridement. In this report, an endoscopic method is described, which achieves the goal of an open surgical debridement but minimizes surgical morbidity.

Burden of disease should impact research prioritisation. ⋯ CDSR representation of external causes of injury strongly correlates with disease burden. The number of systematic reviews and protocols was well aligned for seven out of 12 causes of injury. These results provide high-quality and transparent data that may guide future prioritisation decisions.

Uncontrolled haemorrhage is the leading cause of potentially preventable death in both civilian and military trauma patients. Animal studies and several case series have shown that hemostatic dressings reduce haemorrhage and might improve survival. One of these products is HemCon ChitoGauze(®). The objective of this study was to determine the effectiveness and safety of ChitoGauze in achieving hemostasis in massive traumatic bleeding in civilian emergency medical services. ⋯ This is the largest prospective study in civilian healthcare and the second largest case series with prehospital use of hemostatic dressings. It demonstrated that ChitoGauze is an effective and safe adjunct in the prehospital treatment of massive external traumatic haemorrhage.

Prior analysis demonstrates improved survival for older trauma patients (age>64years) treated at trauma centres that manage a higher proportion of geriatric patients. We hypothesised that 'failure to rescue' (death after a complication during an in-hospital stay) may be responsible for part of this variation. The objective of the study was to determine if trauma centre failure to rescue rates are associated with the proportion of older trauma seen. ⋯ Centres more experienced at managing geriatric trauma are more successful at rescuing older patients with serious complications. Processes of care at these centres need to be further examined and used to inform appropriate interventions.

Among Canadian youth, injury is the most common reason for presentation to the emergency department. Youth who commonly engage in multiple risk-taking behaviours are at greater risk for injury, but is it unknown if this phenomenon is more pronounced in different contexts. We aimed to study relationships between risk-taking behaviours and injury, and variations in such relationships between different environmental and social contexts, among youth in Canada. ⋯ This study furthers understanding of clustered risk-taking phenomena that put youth at increasing levels of injury risk. Higher risks for injury and associated gradients were observed in less structured contexts such as neighbourhoods. In contrast, clustered physical activity behaviours were most related to school injury or sport injury and were more likely to be sustained in a supervised context. Understanding the clustered and cumulative nature of risk-behaviours, and how these vary by environmental and social context, helps to explain potential mechanisms of injury as well as modifiable factors that may be important avenues for intervention.
