Negative pressure wound therapy (NPWT) is becoming routine for the preparation of wounds prior to grafting for wound closure. We have been using both foam- and gauze-based NPWT to prepare wounds for closure prior to skin grafting and have obtained similar proportions of closed wounds; 7/7 for wounds treated with gauze-based NPWT and 11/11 for wounds treated with foam-based NPWT. In our follow-up consultations we observed that skin grafts on the foam-treated patients were less pliable than those on the gauze-treated patients. ⋯ The findings of this preliminary analysis suggest that foam-based NPWT may induce a thicker layer of scar tissue beneath skin grafts than gauze-based NPWT which might explain a reduced pliability of the reconstructed bed. At present it is unclear which mechanism might be responsible for the difference in pressure (-125 versus -80 mm Hg), either the length of the time taken to reconstruct the wound bed or the intrinsic nature of the foam or gauze on the tissue surface. Prospective studies are necessary to investigate whether these preliminary observations are confirmed and to investigate what the mechanism might be.

Randomized Controlled Trial Comparative Study
A randomized, controlled study comparing the cosmetic outcome of a new wound closure device with Prolene suture closing caesarean wounds.
A prospective, randomised study was conducted to compare the wound closure performance and cosmetic outcome of caesarean section wounds closed with traditional Prolene suture or a new wound closure device (Leukosan(®) SkinLink). Sixty-one patients referred to primary section were allocated to wound closure with either Leukosan(®) SkinLink or Prolene suture. ⋯ Both methods of wound closure scored equally high on the visual analogue scale for cosmetic evaluation at the 3-, 6- and 12-month follow-ups as assessed by the patient, surgeon and the blinded observers. The study has shown that innovative methods for wound closure compared with traditional methods such as suture providing excellent cosmetic results represent a valid alternative to physician and patient for surgical incisions.

Comparative Study
Evaluation of chitosan gel containing liposome-loaded epidermal growth factor on burn wound healing.
The objective of this study is to develop a chitosan gel formulation containing liposomes loaded with epidermal growth factor (EGF) and to evaluate their effects on the healing of second-degree burn wounds in rats by immunohistochemical, histochemical and histological methods. EGF-containing multilamellar liposomes which were carried in chitosan gel, EGF gel and EGF-loaded liposome formulations were prepared. The in vivo experiments were performed on female Sprague Dawley rats. ⋯ When the results were evaluated immunohistochemically, there were significant increases in cell proliferation observed in the EGF-containing liposome in chitosan gel (ELJ) formulation applied group (P < 0·001). The histochemical results showed that the epithelisation rate in the ELJ group was the highest compared with the other group results (P < 0·001). The histological results indicated and supported these findings and faster epithelisation was observed in the ELJ group compared with the other groups.
