Review Case Reports
Complex regional pain syndrome in burn pathological scarring: A case report and review of the literature.
Chronic pain in burn pathological scarring is not an uncommon occurrence. The mechanisms of pain are not clearly understood and hence the management approach is often a daunting task. ⋯ We present a patient with classic signs and symptoms of complex regional pain syndrome associated with burn pathological scarring of her left forearm that had a favourable response to a thoracoscopic sympathectomy. The possible pathological mechanisms of burn pathological scarring, mechanisms of pain, and complex regional pain syndrome are reviewed.

Posttraumatic growth after burn is a relatively new area of study with only a small number of studies that have examined this phenomenon. It is important to understand the presentation of posttraumatic growth and coping in burn survivors, how it changes over time and the components which influence growth so that we can understand how to promote posttraumatic growth in burn survivors. The aim of this review was to assess these three parameters. ⋯ Suddenness of the event, and the severity and location of injury might affect the amount of growth experienced. Overall function, quality of life, social support and optimism, hope and new opportunities are influences on growth after burn, all of which have the potential for improvement through targeted intervention strategies. Further research is indicated in many areas related to growth, intervention and measurement.

Review Case Reports
The unusual presentation of a burn from methyl bromide exposure: A case report and review of the literature.
Methyl bromide chemical burns are rare. Only two cases have been reported to date. ⋯ The latency period lasts several hours prior to the development of chemical burn wounds. In this article, we review the literature on methyl bromide chemical burns and present our experience managing a patient with an extensive methyl bromide burn.

Oxidative stress in sepsis: Pathophysiological implications justifying antioxidant co-therapy.
Sepsis is one of the main causes of death among critically ill patients. Sepsis pathogenesis includes infection by gram-negative and gram-positive bacteria, fungi, or both; exacerbated inflammatory response; hypotension, with potential to cause vasodilatory shock; and lesser delivery of oxygen to tissues due to impairment of oxygen utilization by cells. The participation of reactive species and/or free radicals such as nitric oxide (NO), peroxynitrite (ONOO-), superoxide (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (OH) has been reported to underlie these effects. ⋯ In addition, overproduction of NO due to inducible nitric oxide synthase (iNOS) activity has been associated with harmful effects such as general vasodilatation and hypo-responsiveness to therapeutic vasoconstrictor agents. Considering that iNOS expression is regulated by nuclear factor-κB, which may be activated by ROS, antioxidants could inhibit the overexpression of iNOS in sepsis. In line with this, several antioxidants such as vitamins C and E, polyphenols, melatonin, β-glucan, N-acetylcysteine, mitochondrion-targeted antioxidants (MitoQ, MitoE, and peptides associated with dimethyltyrosine), selenium salts, and organoselenium compounds were effective in ameliorating oxidative stress in animal models of sepsis and in a number of clinical trials with septic patients.
