<p><b>OBJECTIVE</b>To review the long-term clinical effect of composite transplantation of allogeneic acellular dermal matrix (ADM) and split thickness skin autograft (STSG).</p><p><b>METHODS</b>Nineteen patients with 34 wounds transplanted with allogeneic ADM combined with STSG who were hospitalized from March 2001 to October 2008 were enrolled as composite transplantation group (CT). Another 9 patients with 11 wounds transplanted with STSG admitted within the same time frame were enrolled as control group (C). All patients were followed up for longer than 2 years. Color, evenness, texture, contracture, sensation, and complications of transplanted skin were assessed using a modified Manchester Scar Scale (1-4 scores, the higher the score, the poorer the situation). The scar formation on skin donor sites was assessed by the Vancouver Scar Scale. Patients' degree of satisfaction and health status during the transplantation period were investigated in the form of questionnaire. The skin tissue structure of 4 patients was observed with histological method. The joint range of motion was assessed by the neutral position before and after operation and at follow-up. Data were processed with nonparametric test, chi-square test or t test.</p><p><b>RESULTS</b>(1) The evenness, contracture, and texture of transplanted skin in CT group scored (1.6 ± 0.5), (1.8 ± 0.8), and (1.5 ± 0.8), respectively, which were significantly lower than those in C group [(2.0 ± 0.7), (2.2 ± 0.9), and (2.3 ± 0.7), with Z value respectively -2.058, -2.220, -2.323, P values all below 0.05]. Scores of color, sensation, and complications of transplanted skin in two groups were close to each other (with Z value respectively -0.628, -0.428, -2.520, P values all above 0.05). (2) Mild scar formation was observed in one of the skin donor sites in CT group. (3) Information as obtained from questionnaire showed no statistical difference between two groups in pinching, itching, and satisfaction degree (with χ(2) value respectively 0.187, 0.019, 2.628, P values all above 0.05). (4) Nerve fibers were seen in hand tissue 2 years after operation. ADM did not induce severe inflammatory responses in the site of grafting. (5) Eleven joints in CT group recovered or improved in function; while the other two joints required secondary surgery. Obvious contracture was observed in the two joints in C group.</p><p><b>CONCLUSIONS</b>Allogeneic ADM combined with STSG transplantation prevents scar contracture and has obvious effect in improving function and appearance. There is no problem in regard to safety for its existence in either adult or children.</p>

<p><b>OBJECTIVE</b>To describe an operative method for the repair of electric burn wound in the upper limbs with lateral intercostal perforator-based pedicled flap, and to observe its clinical effect.</p><p><b>METHODS</b>Intercostal artery perforator-based pedicled abdominal flap with the blood supply originating from the lateral perforator branches of the 7th-10th intercostal arteries were used to repair the wounds of 6 patients with burn wounds in elbows, forearm, wrists and palms. The pedicles were (16. 0 cm x 12. 0 cm) - (9. 0 cm x 7.0 cm) in area, and the pedicles were severed 18 to 21 days after the operation. The survival and the appearance of the flaps were observed after operation.</p><p><b>RESULTS</b>The procedure was easy and safe, and there was reliable and adequate blood supply in the lateral intercostal perforator-based pedicled flap. All the flaps survived in 5 patients, except marginal necrosis (3.5 cm x 2. 0 cm) was found in the distal portion of flap because flap cutting exceeded the paraumbilical line. The appearance was satisfactory after operation.</p><p><b>CONCLUSION</b>This flap is suitable for the repair of deep wounds in hands, forearms, and elbows.</p>

<p><b>OBJECTIVE</b>To investigate the bacterial flora and their drug resistance in hospitalized burn patients on tropical islands.</p><p><b>METHODS</b>Retrospective study was carried out to analyze pathogenic microorganisms and their drug resistance characteristics in 392 burn patients hospitalized during 2000-2005.</p><p><b>RESULTS</b>(1) Totally 671 strains of bacteria were isolated, among which Pseudomonas aeruginosa, Staphylococcus aureus, Aerobacter cloacae and Acinetobacter species were predominant, but the isolation rate of Pseudomonas aeruginosa was declining compared with that in 1990's. (2) The resistance rate of Pseudomonas aeruginosa to imipenem and cefepime was 32.2% and 36.7% , respectively, while that to other antibiotics was above 80%. (3) Among 141 strains of Staphylococcus aureus, 89 strains (63.1%) of MRSA were isolated, and none of them were resistant to Vancomycin.</p><p><b>CONCLUSION</b>Pseudomonas aeruginosa, Staphylococcus aureus, Aerobacter cloacae and Acinetobacter species were predominant in tropical islands. The species of the pathogens are changing . The drug resistance rates of Pseudomonas aeruginosa and Staphylococcus aureus are rather high.</p>

<p><b>OBJECTIVE</b>To present the clinical application of composite graft of acellular allo-dermis matrix (ADM) with thin auto-microskin on burn wound.</p><p><b>METHODS</b>8 inpatients with 18 full thickness skin burn wounds were transplanted with allo-ADM after eschar was excised, then the auto-microskin and allo-human skin were covered on the area of the matrix, the wound where no allo-ADM grafting were covered as control groups only with auto-microskin and allo-human skin. The area of donor to wound is 1:5 - 1:8.</p><p><b>RESULTS</b>Survived rate of 18 pieces composite skin that allo-ADM with auto-microskin were grafted were 94%. After following up for 3 to 13 months, the skins of complex grifting had well elastic and smooth texture compared to auto-microskin grafted, they appeared less cicatrisation and ulceration. 3 months after operation, it was indicated by histological examination that tightknit the epithelial-dermal conjunction and epidermal papilla structure could be identified in the allo-ADM skin and there were orderly collagenous fibres, but scar skin structure was observed in that auto-microskin grifted area.</p><p><b>CONCLUSION</b>The graft effectiveness of allo-ADM and auto-microskin was better than that of auto-microskin, and this method could be used on major deep burn wound healing.</p>
