Development of an easy-to-handle murine model for the characterization of radiation-induced gross and molecular changes in skin.

Background: Radiation-induced skin injury is a dose-limiting complication of radiotherapy. To investigate this problem and to develop a framework for making decisions on treatment and dose prescription, a murine model of radiation-induced skin injury was developed.

Methods: The dorsal skin of the mice was isolated, and irradiation was applied at single doses of 15, 30, and 50 Gy.

Endoscopic-assisted surgical correction for congenital muscular torticollis.

Background: Various surgical approaches have been advocated to release, lengthen, or excise a segment of the sternocleidomastoid (SCM) muscle for the treatment of congenital muscular torticollis (CMT). However, all those conventional methods make noticeable scars on the clavicle or neck area. We proposed the endoscopic-assisted postauricular approach for the treatment of CMT that provides good functional and cosmetic outcomes and less learning curve.
