To introduce and assess a system for the delivery of fibroblast growth factor to autologous cartilage grafts using fibrin sealant and analyze whether this "enhancement" results in reduced rates of cartilage resorption and greater preservation of normal architectural features compared with "unenhanced" cartilage grafts. Methods: Auricular cartilage segments measuring 1 cm 2 were harvested from 12 New Zealand white rabbits, morselized, and implanted into the subcutaneous dorsum of the upper back for 3 months. The conditions included (1) cartilage alone; (2) cartilage + fibrin sealant; (3/4) cartilage+acidic or basic fibroblast growth factor (aFGF or bFGF); and (5/6) cartilage + fibrin sealant +aFGF or bFGF. Subsequent to graft harvest, gross and microscopic assessments were performed to assess size, structural integrity, and architectural features, with comparisons performed between each of the conditions. Results: The mean areas of the harvested cartilage grafts treated with fibrin sealant+aFGF or bFGF were 1.23 cm 2 and 1.19 cm 2 , respectively, while the corresponding value
We describe ({ rare case ofa glomus tumor of the pinna. The lesion produ ced a briefbut sharp pain that occurred spontaneo usly. interm ittently. and upon tactile stimulation. Surgica l exc ision with wide margins was successful. We believe this to be only the third case ofa glomus tumor of the auri cle that has been reported in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
