METHODS: A prospective, randomized, single-blinded control trial was performed on eligible diabetic patients with full-thickness cavity wounds. Patients' demographics, size and site of wounds, and baseline routine blood investigations were recorded. The wounds were dressed every other day with Kelulut honey for the intervention group or gel for the control group. The wound size reduction and granulation tissue formation percentage were calculated every 6 days for 1 month.
RESULTS: Seventy-one patients were randomized. After 30 days of follow-up, 62 participants were available for analysis: 30 from the control group and 32 from the treatment group. The control group had increased granulation tissue at baseline and more wounds on the lower limb and posterior trunk. Both groups showed an increasing mean and median percentage of wound epithelialization and granulation tissue over time, with significantly higher values at every timepoint in the honey group (p
METHODS: Membrane films were prepared from water-soluble O-C solution blended with various concentrations of glycerol to modify the physical properties of the films. In vitro and in vivo biocompatibility evaluations were performed using primary human skin fibroblast cultures and subcutaneous implantation in a rat model, respectively.
RESULTS: Addition of glycerol significantly influenced the barrier and mechanical properties of the films. Water absorption capacity was in the range of 80%-160%, whereas water vapor transmission rate varied from 1,180 to 1,618 g/m2 per day. Both properties increased with increasing glycerol concentration. Tensile strength decreased while elongation at break increased with the addition of glycerol. O-C films were found to be noncytotoxic to human fibroblast cultures and histological examination proved that films are biocompatible.
CONCLUSION: These results indicate that the membrane film from O-C has potential application as a wound-dressing material.
METHODS: We performed a retrospective case note review of patients undergoing foot salvage surgeries and primary talus reconstruction with double-barrel free fibula flaps between 2009 and 2019. Patient demographics, aetiologies, operative details, complications, and outcomes were analysed. All patients underwent the same talar reconstruction technique whereby a wide-based triangular framework was created from two bony struts of the osteotomized fibula. The Musculoskeletal Tumour Society (MSTS) scoring system was used to analyse the short- to mid-term functional outcomes.
RESULTS: Four consecutive patients with aggressive benign and malignant tumours were identified. They consist of three males and one female, with a median age of 32 (range 27-39). Patients were followed up for a median duration of 60 months (range 24-132). Two flaps were complicated with venous thromboses; however, all were salvageable following re-explorations. All patients achieved solid bony fusion with good functional and aesthetic outcomes. The median MSTS score was 74.5% (range 66-76). No donor site morbidity and local recurrence were reported.
CONCLUSION: The triangular double-barrel free fibular flap is a good option for limb salvage following total talus resection, with good short- to mid-term functional and aesthetic outcomes.
