Chemical burns continue to pose a variety of dilemmas to the clinician managing such cases. Assessment of burn depth is often difficult and the decision whether to excise the wound early is not always clear-cut. In this updated review, common agents are classified and the basic principles of management and specific recommendations are examined. The complications arising from exposure to these chemicals and the supportive measures needed during treatment are also described.

The treatment of deep dermal hand burns: How do we achieve better results? Should we use allogeneic keratinocytes or skin grafts?
The treatment of deep dermal burns has a broad spectrum and has been subject to discussion over the past years. The treatment of hand burns is challenging due to the high requirements to aesthetic and functional outcome. 27 patients, 7 women and 20 men with deep dermal hand burns with a mean age of 41.3+/-16.5 and a mean TBSA of 15%+/-19.6% were treated either with allogeneic cryopreserved keratinocytes or with split skin grafts. Long-term follow-up revealed no statistical significant differences between the two groups concerning Vancouver Scar Scale as well as hand function judged by the DASH score; however there was a tendency to higher VSS scores and impaired aesthetic results in the keratinocyte group. ⋯ In our opinion, the cultivation and use of keratinocytes should be reserved to these centres in order to facilitate a sensible application for a full range of indications. We recommend usage of allogeneic keratinocytes for deep dermal hand burns only in severely burned patients with a lack of donor sites. Patients with unrestricted availability of donor sites seem to profit from the application of split-thickness skin grafts according to our results.

Burns are a complex phenomenon with multiple interactive factors. Age, ethnicity and socioeconomic deprivation have been identified in the literature as important determinants of this form of injury. ⋯ This study confirms marked ethnic and socioeconomic disparities in burn injuries requiring hospital admission. This is unacceptable and preventable. We propose active targeting of burn prevention strategies at high-risk groups as a cost-effective way of reducing disparities.

In efforts to prevent and reduce joint contracture and scar formation after burn, we used the acellular human dermis (AlloDerm) as a dermal replacement in the acute stage. A total of 64 patients received AlloDerm graft selectively on joint areas during the study period from March, 2005 to July, 2007. From January to March, 2008, a total of 31 patients returned to our burn center to examine the functional results by measuring range of motion of joints. ⋯ Trans-epidermal water loss for non-AlloDerm applied areas was 20.9+/-7.7 g/h/m(2) and AlloDerm applied areas was 10.8+/-3.4 g/h/m(2) (p<0.001). Erythema value for non-AlloDerm applied areas was 436.1+/-65.8, whereas AlloDerm applied area was 394.4+/-61.2 (p<0.001). Acellular dermal matrix is a good option for treating major burns to prevent scar formation after burn and loss of joint function.

Salvage of the zone of stasis is a major subject of focus in burn research. Use of various antithrombotic, anti-inflammatory and antioxidant drugs have been studied experimentally, with reports of favourable results; however, none became popular in clinical practice. Activated protein C (APC) is a well-known physiologic anticoagulant. ⋯ At day 3, the differences between the results obtained from the treatment and the control groups were found to be statistically significant (p<0.05). Our experimental study revealed that APC improved tissue perfusion and decreased the area of skin necrosis in the zone of stasis in rats. The dual effect of APC, each of which has been shown to be favourable in saving the zone of stasis, may make this agent effective with a single effect in treatment of burn injury.
