Histologic assessment of low-voltage electrical burns: experimental study with pigskin.

The authors have carried out an experimental protocol on pigs, producing identical electrical burns to examine clinically and histologically the evolution of these burns with time. A clinical lesion in the form of a rosette was observed. It was composed of three zones: a central zone of carbonization, a pale ischemic intermediate zone, and an erythematous peripheral zone.

Primary pressure grafts in early reconstruction of deep facial burns.

The face is an area of great cosmetic importance where the repair of deep burns is particularly delicate, as both appearance and function must be taken into account. In order to improve the aesthetic prognosis of full skin thickness facial burns, a primary pressure graft technique was used in eight patients. Early excision was carried out during postburn day 3 and after good-quality granulation tissue was obtained around day 10, a full skin thickness graft was applied.
