BACKGROUND Significant controversy exists regarding when an athlete may return to contact sports after anterior cervical discectomy and fusion (ACDF). Return-to-play (RTP) recommendations are complicated due to a mix of medical factors, social pressures, and limited outcome data. OBJECTIVE The aim of this study was to characterize our diagnostic and(More)
BACKGROUND Photochemical tissue bonding (PTB) is an emerging technique for bonding or sealing tissue surfaces that requires light and a photoactive dye for its effect. The potential of PTB for tendon repair was assessed in a rat model. MATERIALS AND METHODS The optical properties of bovine tendon were determined ex vivo to gauge the depth of light(More)
OBJECTIVES To bond vocal fold flaps using a sutureless, nonthermal laser-assisted method combining visible light and photosensitizing dyes to produce collagen crosslinks. STUDY DESIGN In the ex vivo study, epithelial incisions were created in sheep vocal folds. The concentration of the Rose Bengal, and the laser fluence were varied and studied. The in(More)
Tissue adhesion can be achieved using lasers in a non-thermal process called photochemical tissue bonding (PTB) as well as by the better known processes in which the tissue is heated to achieve welding or soldering. In PTB the energy of the absorbed photons is used to drive photochemical reactions via activated chemical species. Covalent bonds(More)
Heat illness remains a large medical burden for militaries around the world. Mitigating the incidence as well as the complications of heat illness must remain on the forefront of operational planning when operating in hot environments. We report the case of a 27-year-old male U.S. Marine who sustained a heat-related illness resulting in fulminant liver(More)
BACKGROUND Photochemical tissue bonding (PTB) is a novel tissue repair technique that uses visible light and a photosensitizing dye to crosslink proteins on tissue surfaces. This technique has been successfully demonstrated in a number of tissue repair models. An ideal nerve repair technique would be atraumatic and avoid placement of foreign bodies at the(More)
