Choice of the donor site for a split thickness skin graft depends on skin availability, possible complications and anticipated esthetic results. We selected the scalp to be the primary donor site at our institution. During a period of ten years (1998-2008), a group of 123 pediatric patients aged 4 months to 15 years (65% were below the age of 2; mean age 2.98 years) underwent skin grafting from this particular site. In 2 cases the same area was re-harvested. All donor sites healed by the 10th post-operative day. Donor site complications included: 2 microalopecia regions, 5 pressure sores in a close proximity, 1 hypertrophic scar and 1 visible mark on the forehead due to technical mistake in graft harvesting. All children started scar management of the recipient site with contact therapy using adhesive tape Hypafix (BSN Medical); subsequently moving on to silicone sheets or gel in selected refractory cases. We present results for 68 scars in 41 patients with the longest follow-up period. Scar quality was evaluated after minimum of 10 years and scored according to the Vancouver Scar Assessment Scale. Very good and good results were obtained in 55 scars (80.9%), satisfactory in 11 scars (16.2%) and unsatisfactory in 2 scars (2.9%). ⋯ Our results confirm, that the scalp is a reliable donor site in children and contact therapy is an adequate form of scar prevention/treatment of the recipient site.

Severe burns in children are conventionally treated with split-thickness skin autografts or epidermal sheets. An alternative approach is to graft isolated keratinocytes. We evaluated foreskin and other anatomic sites as donor sources for autologous keratinocyte graft in children. We studied in vitro capacities of isolated keratinocytes to divide and reconstitute epidermal tissue. ⋯ Our studies highlight the potential of foreskin tissue for autograft applications in boys. A suitable alternative donor site for autologous cell transplantation in female paediatric burn patients remains an open question in our department. We tested the hypothesis that in vitro studies and RHE reconstructive capacities of cells from different body sites can be helpful to select an optimal site for keratinocyte isolation before considering graft protocols for girls.

Severe burns with delayed resuscitation are associated with high morbidity which is attributed to ischemia-reperfusion injury. This study was undertaken to investigate the effect of hydrogen-rich saline known as a significant selective antioxidant on the inflammatory reaction induced by severe burns with delayed resuscitation. By establishing the model of severe burns with delayed resuscitation in rats, we recorded improvement on the mortality, secretion of cytokines and reaction of oxidative stress of rats treated with hydrogen-rich saline. ⋯ We further detected the change of the key nuclear factor NF-κB contributed to inflammation. The expression of both NF-κB and phosphorylated NF-κB in rats having severe burns with delayed resuscitation by hydrogen-rich saline was lower than that in rats with delayed resuscitation with Ringers' solution. Our data imply that hydrogen-rich saline significantly improves the inflammatory reaction in rats with severe burns with delayed resuscitation, possibly by inhibiting activation of NF-κB.

Glycyrrhizin (Gly) has been reported as an inhibitor of extracellular HMGB1 (high-mobility group box 1 protein) cytokine's activity, and protects spinal cord, liver, heart and brain against ischemia-reperfusion-induced injury in rats. The purpose of this study was to investigate the protective effect of Gly in rat skin thermal injury model and to elucidate the underlying mechanisms. ⋯ These results demonstrate that Gly possesses an anti-inflammation effect to protect the remote organs from burn-induced injury.
