hADSCs may play a key role in nerve regeneration by acting primarily as support for local neurotrophic mediation and modulation of nerve growth rather than that of a primary neuronal differentiation agent. © 2013 Wiley Periodicals, Inc. Microsurgery 34:324–330, 2014. “
“Microsurgical

revascularized fibula graft is a standard for the reconstruction of mandible or maxilla after major resection. Usually, screwed implants are inserted as a second procedure for dental rehabilitation. A lot has been published about the advantages of vascularized bone grafts, but PF-02341066 mw until now there is only little information about long-term viability of inserted bone grafts. In this study, previously inserted vascularized fibula bone grafts were examined histologically. Bone biopsies were taken during dental implant insertion procedure in average of 19 months after insertion of bone grafts from 10 patients. All bone biopsies showed partially or totally necrotic bone, although clinical examination and postoperative monitoring of the revascularized bone remained

unremarkable. The results of histological examination are surprising, due to the fact of previous insertion of a vascularized bone graft and pretended osseointegration of inserted dental implants with satisfying primary stability. Therefore, one would expect vital bone. For better understanding how much viability is really necessary for sufficient remodeling of HDAC assay inserted bone grafts for adequate functional load, further studies should be performed. © 2011 Wiley-Liss, Inc.

“Background: The Iraq and Afghanistan Wars have presented military reconstructive surgeons with a high volume of challenging extremity injuries. In recent years, a number of upper and

lower extremity injuries requiring multiple tissue transfers for multiple limb salvages in the same casualty have been encountered. Our group will discuss the microsurgical challenges, algorithms, and success and complication rates for this cohort of war injured patients. Methods: during All consecutive limb salvage cases requiring free flaps from 2003 to 2012 were reviewed. Cases involving simultaneous free tissue transfers were identified. Data collected included success rates and complications with comparisons made between the single and multiple free-flap limb salvage cohorts. Results: Seventy-four free flap limb salvage cases were performed over the 10-year period. Of these cases, four patients received two free flaps to separate upper and lower extremity injuries for limb salvage within a single operative setting. The complication rate was 63%, which was significantly higher than those cases in which a single microvascular anastomosis was performed (26%, p = 0.046). However, the higher complication rate did not increase the flap or limb salvage failure rates (p = 0.892 and 0.626).
