Total face, double jaw, and tongue transplantation: an evolutionary concept.

BACKGROUND: The central face high-energy avulsive injury has been frequently encountered and predictably managed at the R Adams Cowley Shock Trauma Center. However, despite significant surgical advances and multiple surgical procedures, the ultimate outcome continues to reveal an inanimate, insensate, and suboptimal aesthetic result. METHODS: To effectively address this challenging deformity, a comprehensive multidisciplinary approach was devised. The strategy involved the foundation of a basic science laboratory, the cultivation of a supportive institutional clinical environment, the innovative application of technologies, cadaveric simulations, a real-time clinical rehearsal, and an informed and willing recipient who had the characteristic deformity. RESULTS: After institutional review board and organ procurement organization approval, a total face, double jaw, and tongue transplantation was performed on a 37-year-old man with a central face high-energy avulsive ballistic injury. CONCLUSIONS: This facial transplant represents the most comprehensive transplant performed to date. Through a systematic approach and clinical adherence to fundamental principles of aesthetic surgery, craniofacial surgery, and microsurgery and the innovative application of technologies, restoration of human appearance and function for individuals with a devastating composite disfigurement is now a reality. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

Antibody-mediated rejection of renal allograft in combined liver-kidney transplant.

Liver transplantation is performed based on ABO blood type compatibility without dependence on crossmatch results. Combined liver-kidney transplantation (CLKT) is similarly performed without dependence of crossmatch results as the liver is thought to confer protection to the renal allograft against alloantibody. We report a case of CLKT in a sensitized patient with antibody-mediated rejection (AMR) of the renal allograft. AMR was confirmed with C4d staining and serial monitoring of donor-specific antibody (DSA). Despite intensive therapy directed against AMR and the presence of the liver allograft, the patient demonstrated increasing titers of alloantibody, never demonstrated adequate renal function, and ultimately expired after two months. This result demonstrates the potential for AMR of the renal allograft in sensitized recipients of CLKT.

Acute graft-versus-host disease in pancreas transplantation: a comparison of two case presentations and a review of the literature.

As a complication of solid organ transplantation, acute graft-versus-host disease (GVHD) is most associated with small bowel and liver transplants. We present two cases of acute GVHD following pancreas transplantation. Case 1 was a 27-year-old female who underwent cadaveric pancreas transplant 9 months after a successful live donor kidney transplant. Case 2 was a 38-year-old male who received a simultaneous cadaveric pancreas and live donor kidney transplant. Both patients presented within 30 days of transplant with nonspecific symptoms. Rejection and infection were ruled out. Both subjects had progressive decline in mentation associated with pancytopenia and hyperbilirubinemia. Rash was not present until late in their hospital course. Skin biopsies demonstrated mixed chimerism with pancreas donor DNA diagnostic of GVHD. Acute GVHD is a rare, often fatal, complication of pancreas transplantation, and its presentation appears to differ from acute GVHD associated with stem cell transplantation.
