Chitin nanofibers were acetylated to modify the fiber surface and were characterized in detail. The acetyl DS could be controlled from 0.99 to 2.96 by changing the reaction time. FT-IR spectra indicate that chitin nanofibers were acetylated completely after 50 min reaction time. X-ray diffraction profiles and TGA curves show that the chitin nanofibers were(More)
AIM OF THE STUDY Pediatric hand deep dermal and deep burns may lead to serious hand deformity with functional impairment and result in an esthetically unfavorable outcome. Since there is no guideline regarding the use of growth factors for pediatric hand burns, we sought to investigate the effectiveness of an angiogenic and regenerative growth factor, basic(More)
Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder characterized by café-au-lait spots and neurofibroma. Vascular NF-1 lesions are rare, but bleeding from such lesions can sometimes cause lethal complications because surgical hemostasis is difficult to achieve due to the fragile nature of the surrounding blood vessels and soft tissue. In(More)
The sural nerve has been described for nerve reconstruction of the maxillofacial region since it provides many advantages. We report a case of a vascularized sural nerve graft based on a peroneal artery perforator for immediate reconstruction after the removal of intraosseous neuroma originating in the inferior alveolar nerve. The patient had a neuroma(More)

AIM OF THE STUDY Cranial bone-exposing wounds should be resurfaced as soon as possible using flaps. However, early one-stage wound closure is sometimes difficult due to the poor general condition of the patient or equipment shortages. Artificial dermis composed of atelocollagen sponge is useful for reconstructing bone-exposing wounds. In addition, the(More)
