Case report of the first Caucasian burn patient transplanted with Cutimed Sorbact®-based cultured epithelial autografts technique at Tygerberg Hospital, Cape Town, South Africa: An 8-year follow-up.

Cultured epithelial autograft applications are limited by the associated cost and time constraints in resource-limited settings. A modified composite technique using the patients' own tissue and Cutimed Sorbact dressing was employed as a life-saving emergency measure. Since the non-Caucasian population was more commonly treated at the center, it was important to report the first Caucasian patient outcome, as the graft-take outcome for all populations was unknown. A 54-year-old male with extensive flame burns and a low chance of survival was admitted to the Tygerberg Burn Center. He received traditional skin grafts and cultured epithelial cells, after the 2 week-culture period using the current technique. Short- (⩽2 weeks) and long-term graft take (⩽8 years) was inspected. Good graft take and complete epithelialization was observed during short-term inspection with partially healed areas initially attributed to extensive burn depth and dressing removal. Long-term follow-up indicated a near normal tissue appearance and excellent pliability.

Graft take outcomes of burn patients transplanted with CEA derived from a modified composite culture technique: A case series.

Low-cost and efficient culture environments comparable to standard techniques would undoubtedly improve burn outcomes in under-resourced settings. The aim of this case series was to report on the CEA graft-take using a modified composite culture technique. CEA transplants, following emergency ethical approval, occurred for burn patients (n=25) with low survival prognosis and/or exhausted donor sites. Keratinocytes were retrieved from skin biopsies, seeded centrally on routinely-used dressing gauze and incubated at 37 °C in pediatric incubators. Fresh autogenous plasma was applied daily and hydrogel every third or fourth day. After confluence, the CEA was transplanted onto debrided wound beds. Xenografts were used for temporary cover during the culture period. Final graft take assessment (21 days) was assessed and calculated as a graft take percentage for total CEA area transplanted. Central indices were described as mean (95% CI) and frequency (%) for age, total body surface area, abbreviated burn severity index scores, survival prognosis and graft take. Eleven patients survived with a mean age of 36.1 years (95% CI 25.8-46.4), 45.0 %TBSA burns (95% CI 35.1-54.9), 9.7 ABSI scores (95% CI 8.6-10.8) and 79.5% graft take (95% CI 62.9-96.0). Reduced graft take (61.2%) was observed in patients with perineum burns and increased graft take (97%) in uncomplicated burns. The average CEA graft take was 79.5% using a low-cost culture technique and comparable to the largest case series in literature. The survival of the major burn cases was highly favourable considering injury severity, expected outcomes without CEA and the observed challenges.

Ventral onlay glanuloplasty for treatment of fossa navicularis strictures

ABSTRACT Purpose: Management of fossa navicularis (FN) strictures balances restoring urethral patency with adequate cosmesis. Historically, FN strictures are managed via glans cap or glans wings, and in severe cases, multi-stage procedures. Ventral onlay glanuloplasty (VOG) is an easily reproducible technique that involves a single-stage augmentation with buccal mucosal graft. We have been applying this technique for several years and present early promising outcomes of this novel approach. Materials and Methods: We retrospectively reviewed all patients with FN strictures who underwent VOG at our institution. Treatment success was designated by the absence of extravasation on voiding cystourethrogram and no need for further urethral instrumentation on follow up. Glans cosmesis was assessed by patients providing binary (yes/no) response to the satisfaction in their appearance. We also noted stricture length, stricture etiology, demographic characteristics and any post-operative complications and reported median, interquartile range (IQR) and count, frequency (%), accordingly. Results: Ten patients underwent VOG and fit our inclusion criteria. Median stricture length was 2.0 cm (IQR 1.6 -2). Success rate was 90% (9/10) with a median follow up of 30 months (IQR 24.3 - 36.8). The one recurrence was treated by dilation combined with triamcinolone injection at 419 days post-op. Stricture etiology included primarily iatrogenic causes such as transurethral prostate resection (4/10), greenlight laser vaporization (2/10), cystolitholapaxy (1/10), and traumatic catheterization (3/10). All patients were satisfied with penile cosmesis. Conclusion: VOG is a simple technique for treating FN strictures. Based on our preliminary series, VOG provides sustained distal urethral patency and patients are pleased with the appearance.
