Prophylactic treatment of deep dermal burn scar to prevent hypertrophic scarring using the pulsed dye laser: a preliminary study.
The pulsed dye laser, by selectively targeting blood vessels, has been used to treat established hypertrophic scars with good effect. This prospective clinical study aims to assess the feasibility of treating deep dermal burn wounds prophylactically before the formation of hypertrophic scars. Patients with burn wounds that took longer than 2 weeks to heal were primarily recruited. ⋯ No notable side effects were seen in all patients. Prophylactic treatment of burn wounds with the pulsed dye laser is effective in hastening the resolution of scarring. In the authors' opinion, this treatment may revolutionize the traditional method of hypertrophic burn scar prevention, and should be considered early, especially for patients who are prone to hypertrophic scarring, and in areas where hypertrophic scarring are common.

Reinnervation of denervated muscle in a split-nerve transfer model.
This study was performed to quantify the reinnervation of denervated muscle in a split-nerve transfer model and to determine any possible downgrading effects on the donor nerve and its end organ. Fifty-four adult Wistar rats weighing 200 to 250 g were used. The experimental design consisted of two groups. ⋯ The difference between the experimental side and the untouched normal healthy side was not significant in the weight measurements of both muscles. The results show acceptable reinnervation by split-nerve transfer with minimal functional impairment of the donor muscle. This study confirms that split-nerve transfer is a reliable method of reconstruction for paralyzed muscle with minimal donor area morbidity.
