Cultured epithelial autografts (CEAs) have long been used to tackle limited donor site availability and difficulty of permanent skin coverage in massive burns, but this approach still has limited documentation. ⋯ Although complex and costly, CEAs can be used with reasonable success and satisfying survival results for the treatment of massive burns. In this study, favorable outcome was principally associated with young age and low number of infectious complications.

We address the clinical application of the suspension type cultured epithelial autografts (CEAs), Keraheal™ (MCTT, Seoul, Korea), along with the effects, application method, merits and demerits thereof. From February 2007 to June 2010, 29 burn patients with extensive burns, participated in the suspension type of CEA clinical test. A widely meshed autograft (1:4-6 ratio) was applied to the wound bed and the suspension type CEA was sprayed with a Tissomat cell sprayer, followed by a Tissucol spray, a fibrin sealant. ⋯ The Vancouver burn scar scale was 5 (4-6.5), 4 (3-6), and 3 (2-4) at 8, 12 and 24 weeks after the Keraheal™ application. Widely meshed autograft must be applied in massive burns but it's take rate is greatly reduced. The CEAs enhance the take rate of a wide meshed autograft in massive burns and allow for grafting wide meshed autograft together with acellular dermal matrix in some cases.

Function of the skin lymphatics as well as blood perfusion of a meshed transplant is crucial for the healing. The lymphatic regeneration and arterial perfusion of skin transplants after severe burns of the extremities had been studied in eight patients by microlymphography, laser doppler perfusion imaging and transcutaneous oxygen pressure measurements 1, 6 and 18 months after transplantation. One month after transplantation, only fragmented as well as many giant lymphatic skin vessels were present in the transplant. ⋯ By contrast, transcutaneous oxygen measurement (TcPO(2)) increased from 44 (21-47) to 55 (50-76) mmHg. In meshed transplants used to cover severely burned skin morphological and functional normal lymphatics develop within 6 months and the initially increased laser flux due to inflammatory reaction normalises. Our results provide important insights into the healing process of skin transplants after burn.

With increasing numbers of illicit drug users in both urban and rural communities, users and producers are becoming increasingly enterprising in their sourcing of mind altering drugs. An example of this is the 'amateur' production of methamphetamine in domestic dwellings. We describe the mechanism of burn seen in methamphetamine production, the pattern of clinical injury, and the difficulties in treating these patients. ⋯ Methamphetamine laboratory explosion burns are difficult injuries from the start. Invariably the true circumstances surrounding the injury are not clear, and clinicians should be suspicious of a meth lab explosion in suspect individuals with burns plus airway injury. Patient management is complex and often requires substantial analgesic and anxiolytic medication in conjunction with clinical psychology and psychiatry as an inpatient.
