Thus, the necessity for judicious management poses significant challenges to surgeons in order to avoid potential permanent disabilities. We report a case of massive penoscrotal skin avulsion and a composite graft was creatively applied to cover the defect which achieved good results. We believe that this case is of great reference value for fellow surgeons.CASE SUMMARY A 52-year-old male presented with massive traumatic avulsion of the penile and scrotal skin following mishandling of an electric drill. The avulsed skin was missing. The patient was diagnosed with massive skin avulsion of external genitalia. Following initial complete debridement of devitalized or infected tissues, Pelnac dermal substitute was secured to the defect with the assistance of negative-pressure wound closure. In the final step, the silicone layer of Pelnac was removed and a split-thickness skin graft was applied. The defect had healed at the two-month follow-up. The patient now has normal erections and satisfactory sexual function.CONCLUSION Our experience with this wound repair demonstrated that the combination of a dermal regeneration template and a split-thickness skin graft with vacuumassisted closure is a safe, well-tolerated and efficient solution for the reconstruction of massive penoscrotal skin defects.展开更多

All selected patients had wide excision following biopsy. To determine the correlation of gender, age distribution and cancer absence, BCC and SCC cases were separated based on excision-cancer absent or present after wide excision. χ2 tests, Fisher's exact tests were used to analyze the ratio of male to female between excision-cancer absent and excision-cancer present patients, while Mann-Whitney U test were used to compare the age distribution in the two groups. Statistical analyses were performed using SPSS version 16.0 for Windows.RESULTS: Our retrospective chart review of the patients showed that cancer cells were absent in 49% of BCC patients(n = 100) and 64% of SCC patients(n = 100) who had previously had positive margins upon biopsy. Gender analysis showed the ratio of male to female(M/F) in the BCC arm was significantly higher compared with the SCC arm in those with excision-cancer absent(2.06 vs 0.66; P = 0.004; χ2 test). But M/F of excision-cancer absent and excision-cancer present in neither BCC nor SCC patients was statistically significant. Age adjustment showed no significant difference between excision-cancer absent and excision-cancer present in BCC and SCC patients. Nevertheless, in excision-cancer absent cases, the age distribution showed that the BCC patients were younger than SCC patients(average age 67 vs 74; P < 0.001; Mann-Whitney U test). In addition, our data also indicated that in the patient group of 71-80 years old, there were more SCC patients who showed excision-cancer absence(67.6% vs 39.4%; P = 0.02; χ2 test).CONCLUSION: Our study indicates that approximately 50% or more of BCC and SCC patients with positive margins found on biopsies did not have cancer cells present at the time of wide excisions.展开更多

The most advanced and expensive dressings have been compared to the most basic of dressings, with little or no consensus and an unpersuasive level of evidence. We aimed to determine the efficacy of the locally manufactured non-adherent, hydroconductive Drawtex? dressing and compare it to our current standard-of-care dressing, a thin transparent polyurethane film, in the healing of split-thickness donor sites. Methods: This prospective, within-patient controlled study included 27 adult participants, each with two split-thickness skin donor sites. The 54 donor site wounds were compared with regard to time to re-epithelialisation, perceived pain and healed wound quality. Results: By day 5, complete healing of donor site wounds, defined as >90% of epithelialized surface, was significantly higher in the hydroconductive dressing group compared to the polyurethane film group (22.2% and 3.7%, respectively;p < 0.0001). The hydroconductive dressing-treated donor site wounds were significantly less painful at 24-hours, 48-hours and 7-days post-operatively, and had fewer complications and superior wound healing quality. Conclusion: We have demonstrated that the relatively cheap and readily available dressing made locally in South Africa, Drawtex? is at least as safe, and potentially superior in wound healing, when compared to our current standard-of-care dressing.展开更多

All three were in current use within the Pegg Leditschke Children's Burn centre (PLCBC), the largest paediatric burns centre in Queensland, Australia. Our objective was to find the best performing dressing, following on from previous trials designed to rationalise dressings for the burn wound itself. Methods:All children for STSG, with thigh donor sites, were considered for enrolment in the trial. Primary outcome measures were days to re-epithelialisation, and pain. Secondary measures were cost, itch, and scarring at 3 and 6 months. Patients and parents were blinded to group assignment. Blinding of assessors was possible with the dressing in situ, with partial blinding following first dressing change. Blinded photographic assessments of re-epithelialisation were used. Scar assessment was blinded. Covariates for analysis were sex, age, and graft thickness (as measured from a central biopsy). Results:There were 101 patients randomised to the Algisite?M (33), Cuticerin?(32), and Sorbact? (36) arms between April 2015 and July 2016. All were analysed for time to re-epithelialisation. Pain scores were not available for all time points in all patients. There were no significant differences between the three arms regarding pain, or time to re-epithelialisation. There were no significant differences for the secondary outcomes of itch, scarring, or cost. Regression analyses demonstrated faster re-epithelialisation in younger patients and decreased donor site scarring at 3 and 6 months with thinner STSG. There were no adverse effects noted. Conclusions:There are no data supporting a preference for one trial dressing over the others, in donor site wounds (DSW) in children. Thinner skin grafts lead to less donor site scarring in children. Younger patients have faster donor site wound healing. Trial registration:Australia and New Zealand Clinical Trials Register (ACTRN12614000380695).
