Abstract
This study focused on detecting the reflections of healing and change in cortex activation in full-face transplantation and lesions patients on EEG activity. Face transplant patients have facial lesions before transplantation and, to identify pre-face transplant patients' brain activity in the absence of pre-transplant recordings, we used data obtained from pre-transplant facial lesion patients. Ten healthy, four facial lesion and three full-face transplant patients participated in this study. EEG data recorded for four different sensory stimuli (brush from the right face, right hand, left face, and left-hand regions) were analyzed using wavelet packet transform method. EEG waves were analyzed for standard bands. Our findings indicate significant change in the 2-4 Hz frequency range which may be a result of ongoing or previous cortical reorganization for face lesion and transplant patients. Alterations of the delta wave seen in patients with facial lesion and face transplant can also be explained by the intense central plasticity. Our findings show that the delta band differences might be used as a marker in the evaluation of post-transplant cortical plasticity in the future.

Acute Rejection Rates in Vascularized Composite Allografts: A Systematic Review of Case Reports. J Surg Res 2024; 298:137-148. [PMID: 38603944 DOI: 10.1016/j.jss.2024.02.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 01/20/2024] [Accepted: 02/29/2024] [Indexed: 04/13/2024]
Abstract
INTRODUCTION Vascularized Composite Allografts (VCA) are usually performed in a full major histocompatibility complex mismatch setting, with a risk of acute rejection depending on factors such as the type of immunosuppression therapy and the quality of graft preservation. In this systematic review, we present the different immunosuppression protocols used in VCA and point out relationships between acute rejection rates and possible factors that might influence it. METHODS This systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We systematically searched Medline (PubMed), Embase, and The Cochrane Library between November 2022 and February 2023, using following Mesh Terms: Transplant, Transplantation, Hand, Face, Uterus, Penis, Abdominal Wall, Larynx, and Composite Tissue Allografts. All VCA case reports and reviews describing multiple case reports were included. RESULTS We discovered 211 VCA cases reported. The preferred treatment was a combination of antithymocyte globulins, mycophenolate mofetil (MMF), tacrolimus, and steroids; and a combination of MMF, tacrolimus, and steroids for induction and maintenance treatment, respectively. Burn patients showed a higher acute rejection rate (P = 0.073) and were administered higher MMF doses (P = 0.020). CONCLUSIONS In contrast to previous statements, the field of VCA is not rapidly evolving, as it has encountered challenges in addressing immune-related concerns. This is highlighted by the absence of a standardized immunosuppression regimen. Consequently, more substantial data are required to draw more conclusive results regarding the immunogenicity of VCAs and the potential superiority of one immunosuppressive treatment over another. Future efforts should be made to report the VCA surgeries comprehensively, and muti-institutional long-term prospective follow-up studies should be performed to compare the number of acute rejections with influencing factors.

Abstract
ABSTRACT Hand transplantation for upper extremity amputation provides a unique treatment that restores form and function, which may not be achieved by traditional reconstruction and prosthetics. However, despite enhancing quality of life, hand transplantation remains controversial, because of immunological complications, transplant rejection, and medication effects. This systematic literature review sought to collect information on current experiences and outcomes of hand transplants to determine the efficacy and utility of hand transplants. The databases PubMed, Scopus, and Embase were analyzed with combinations of "hand" or "upper extremity" or "arm" and "transplant" or "allograft," with information collected on recipient characteristics, details of transplant, immunological outcomes, functional outcomes, and complications. Functional outcomes, as measured by Disabilities of Arm, Shoulder and Hand score, were compared between patient groups using Wilcoxon signed-rank test or 1-way analysis of variance test and post hoc Tukey test. Within the 108 articles that fulfilled inclusion and exclusion criteria, there were 96 patients with 148 hand transplants. There were 57 patients who experienced acute rejection and 5 patients with chronic rejection. Disabilities of the Arm, Shoulder and Hand scores significantly decreased after hand transplantation and were significantly lower for distal transplants compared with proximal transplants. There were 3 patients with concurrent face transplantation and 2 patients with simultaneous leg transplants. Sixteen patients experienced amputation of the hand transplant, and there were 5 deaths. This study found that hand transplantation provides significant restoration of function and form, especially for proximal transplants. Reduction in complications, such as rejection and amputation, can be achieved by decreasing medication cost and patient education.

Psychometric evaluation of the disabilities of the arm, shoulder and hand (DASH) in patients with orthopedic shoulder impairments seeking outpatient rehabilitation. J Hand Ther 2021; 34:404-414.

Abstract
STUDY DESIGN This is a cross-sectional, observational study. INTRODUCTION The disability of the arm, shoulder and hand (DASH) questionnaire is an upper-extremity specific outcome measure commonly used in routine clinical care and clinical trials. PURPOSE OF THE STUDY Our purposes were to: (1) examine the psychometric properties of the DASH questionnaire using factor analysis, one- and two-parameter item response theory models, and (2) develop a functional staging map illustrating the relationships between the item difficulty hierarchy of the DASH items and the patient's DASH total score. METHODS Data from 2724 patients with orthopedic shoulder impairments seeking outpatient physical therapy in 79 clinics in the US were analyzed. RESULTS Factor analysis supported a general factor, explaining 62.2% of the total variance. The coverage of DASH items was suitable for patients with shoulder impairments with no ceiling or floor effect. Endorsed items representing the most difficult items were related to feeling less capable, executing recreational activities with force or impact, and performing recreational activities in which you move your arm freely. Items with higher discriminating abilities were those related to do heavy household chores, garden/yard work, and change a light bulb overhead. With a separation index equaled to 4.94, the DASH can differentiate persons into at least 6 statistically distinct person strata. None of the DASH items exhibited differential item functioning by gender or symptom acuity, except two items by age group. DISCUSSION Besides a total (summed) final score obtained from a specific measure, the keyform and functional staging plots/maps can be used to assist clinicians in clinical interpretation of the scores. CONCLUSIONS Results supported the clinical usage of the DASH questionnaire in patients with orthopedic shoulder impairments seeking outpatient rehabilitation.

Abstract
Composite tissue allotransplantation (CTA) is the culmination of progress in transplantation, allowing the reconstruction of the hand in amputees. Worldwide, more than 100 procedures have been performed. The aim of this work was to understand the hand allotransplantation approach, making known current aspects, risks, and benefits. A PubMed research was realized between October 2018 and March 2019, including terms like "Hand transplantation" AND "Composite tissue allotransplantation," "Hand transplantation" AND "Functional outcomes," "Hand transplantation" AND "Immunosuppression," "Hand prosthetics," "Hand Transplantation" AND "Ethics." There were included papers between 1995 and 2018, with English language, amputee human adults, systematic reviews, and clinical studies. Seventy-two papers were fully evaluated. There are technical aspects that influence the procedure like team coordination or surgical technique. It requires a long-life treatment, which has risks such as toxicity or infections. However, it allows the recovery of fine movements, and independence, to perform detailed tasks. The indications must be carefully considered, because some patients benefit from the use of prosthesis. CTA has become an option for amputees so it is important to do more research, to determine the benefits of this procedure. It is not considered a life-saving procedure, so there is an ethical debate because of the risks.

Abstract
Several methods can be used for identifying tissues for transfer in donor-site-depleted patients. A fillet flap can be temporarily stored in other parts of the body and transferred back to the site of tissue defect, including covering the amputated stump of the lower extremity. Human arm transplant is rare and has some unique concerns for the surgery and postsurgical treatment. Cosmetics of the narrow neck of transferred second toes can be improved with insertion of a flap. Lymphedema of the breast after cancer treatment can be diagnosed with several currently available imaging techniques and treated surgically with lymphaticovenous anastomosis.

Abstract
Hand transplantation is the most common form of modern composite tissue allotransplantation, with 89 cases reported worldwide since 1998. The procedure is a treatment option for complex injuries that leave patients with structural, functional, and aesthetic deficits that cannot be addressed by other means. Successful application of this technology requires a multidisciplinary approach, incorporating not only skilled hand surgeons, transplant surgeons, and transplant immunologists, but also hand therapists, psychiatrists, medical specialists, anesthesiologists, and so on. Its long-term results depend on proper patient selection, a technically successful operation, postoperative rehabilitation, and an immunotherapy protocol that prevents rejection. Recent advances in transplant immunology are shifting the focus from immunosuppression to immunoregulation. Despite the enormous antigen load associated with composite tissue allografts, hand transplant has become a clinical reality, with immunosuppression comparable to that of solid-organ transplants. Our understanding of hand transplantation is still evolving, and ongoing research is needed to improve functional outcomes and to decrease the morbidity associated with long-term immunosuppression. This review discusses the current protocols for upper extremity donation, transplant receipt, surgical techniques, postoperative rehabilitation and immunosuppression, nerve regeneration, functional outcomes, ethical issues, and financial considerations.

Abstract
BACKGROUND As we enter an age with new approaches to tissue reconstruction, the emphasis on the adage "like for like" has become even more relevant. This study illustrates the potential for several tailored vascularized composite allotransplantation reconstructive techniques and, in particular, for the management of Volkmann contracture. METHODS Twenty fresh cadaver dissections and 30 archival lead oxide radiographic studies were examined to (1) identify potential upper limb vascularized composite allotransplantation donor sites (i.e., elbow, forearm, and flexor tendon complex) and (2) demonstrate a "mock transplant" of the vascularized volar forearm allograft for a severe Volkmann ischemia defect. They were designed without skin to reduce antigenicity. RESULTS The elbow joint was supplied within the brachial angiosome and the flexor tendon complex of the flexor digitorum superficialis and flexor digitorum profundus by the superficial palmar arch of the ulnar angiosome. The forearm allograft of flexor muscles, median, ulnar, and anterior interosseous nerves, when harvested on the brachial vessels, was supplied within the radial, ulnar, and anterior interosseous angiosomes but could be based on the ulnar artery alone because of intramuscular connections with the other territories. A mock transplant was performed with a distal-to-proximal dissection of the allograft, facilitating the best and fastest technique. CONCLUSIONS This application of the angiosome concept highlights the anatomical feasibility of the volar forearm vascularized composite allotransplantation donor site focusing on a complex subunit problem in the upper limb-severe Volkmann ischemic contracture. It demonstrates the potential use and immunologic advantage of subdivided and modified nonskin variations of vascularized composite allotransplantation in reconstructive transplantation surgery.

Abstract
The objective of this review is to summarize the collective knowledge regarding the risks and complications in vascularized composite tissue allotransplantation (VCA), focusing on upper extremity and facial transplantation. The field of VCA has entered its second decade with an increasing experience in both the impressive good outcomes, as well as defining challenges, risks, and experienced poor results. The limited and selective publishing of negative outcomes in this relatively new field makes it difficult to conclusively evaluate outcomes of graft and patient survival and morbidities. Therefore, published data, conference proceedings, and communications were summarized in an attempt to provide a current outline of complications. These data on the medical complications of VCA should allow for precautions to avoid poor outcomes, data to better provide informed consent to potential recipients, and result in improvements in graft and patient outcomes as VCA finds a place as a therapeutic option for selected patients.

Abstract
Psychosocial factors are important elements in the assessment and follow-up care for vascularized composite allotransplantation (VCA) and require multidisciplinary evaluation protocols. This review will highlight differences between VCA with solid organ transplantation (SOT), provide information on the psychosocial selection of VCA candidates, ethical issues, psychological outcomes, and on the need for multicenter research. VCA is primarily a life-enhancing procedure to improve recipients' quality of life and psychological well-being and it represents a potential option to provide reproduction in case of penile or uterine transplantation. The risk benefit ratio is distinctly different than SOT with candidates desiring life enhancing outcomes including improved body image, return to occupations, restored touch, and for uterine transplant, pregnancy. The Chauvet Workgroup has been convened with membership from a number of transplant centers to address these issues and to call for multicenter research. A multicenter research network would share similar evaluation approaches so that meaningful research on psychosocial variables could inform the transplant community and patients about factors that increase risk of non-adherence and other adverse psychosocial and medical outcomes.

Abstract
BACKGROUND The clinic era of composite tissue allotransplantation was inaugurated by hand allotransplantation in 1998, giving rise to many controversies and scepticism because of the lifelong immunosuppression, the unclear risk-benefit ratio, and the uncertain long-term functional results of the procedure. The aim of this study was to evaluate the outcomes and the risk/benefit balance in bilateral hand allotransplantation. METHODS The study included 5 cases of bilateral hand allotransplantation performed in a single center, with a follow-up ranging from 3 to 13 years. The recipients (4 men, 1 woman) were young. The level of amputation was distal in all cases except for 2 patients amputated at the midforearm level. All the recipients initially received the same immunosuppressive treatment that included tacrolimus, mycophenolate mofetil, prednisone, and, for induction, antithymocyte globulins. RESULTS Patient and graft survival was 100%. All recipients showed adequate sensorimotor recovery (protective and tactile sensitivity and partial recovery of intrinsic muscles), they were able to perform the majority of activities of daily living, and had a normal social life. Most complications occurred in the first posttransplant year and were successfully managed. All recipients experienced at least 1 episode of acute rejection, which was easily reversed by increasing oral steroid dose or by intravenous steroids, except for patient 3, who presented 6 episodes of acute rejection, the latest 2 treated with Campath-1H. CONCLUSIONS Although bilateral hand transplantation may be a satisfactory treatment option for amputees, a careful selection of candidates and a rigorous evaluation of recipients after transplantation are imperative.

Abstract
PURPOSE To evaluate the variability of reported baseline Disabilities of the Arm, Shoulder, and Hand (DASH) scores for non-acute hand and wrist conditions. We hypothesized that DASH scores for evaluation of hand and wrist pathology would provide a map of scores that would correspond to severity. In addition to providing a catalog of DASH scores for various upper extremity pathologies, we hypothesized that this review would support the validity of the DASH instrument. METHODS A literature search was performed using 3 databases (MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials) from the earliest available date through January 1, 2013. Search terms included "DASH" and "hand" and combinations of conditions found in the initial search. The search was restricted to studies with baseline DASH scores and DASH scores for isolated conditions, and written in the English language. RESULTS Our search identified 1,770 citations; 136 full-text articles were reviewed and 85 studies were included in the scoping review. This provided 100 DASH scores mapped for 24 different diagnoses. Most articles (67%) included chronic conditions for inflammatory or degenerative pathologies rather than posttraumatic disorders. Posttraumatic DASH score reporting ranged from 4 months to 11 years after injury, and final outcome scores varied among studies assessing the same pathology. The greatest variation and highest scores were for de Quervain tendinitis (range, 29-93) and scapholunate advance collapse (range, 17-89). These scores indicated higher disability in de Quervain tendinitis and wrist osteoarthritis compared with conditions such as thumb amputation and upper extremity replantation. CONCLUSIONS Substantial variation in the DASH scores and methodology was found and indicates a need for further study of the DASH to allow for standardized interpretation.

Abstract
PURPOSE OF REVIEW Psychosocial aspects are important indicators for reconstructive hand transplantation (RHT). They warrant further research attention given the influence of psychosocial factors on the success of RHT. This review will contrast RHT with solid organ transplantation, provide information to guide selection of RHT candidates and ethical implications, share information on psychological outcomes, and address the importance of a multicenter research approach. RECENT FINDINGS Previously published RHT reports have tried to identify psychosocial factors that are essential to guide selection of RHT candidates and that predict psychosocial outcomes. These issues in RHT are receiving increased attention, but standardized psychosocial evaluation and follow-up protocols are still needed. Recent study highlights the potential for a multicenter research approach that uses standardized assessment strategies and also emphasizes the need for a shared assessment approach to understand psychosocial outcomes. SUMMARY RHT combines the technical rigors of hand surgery and microsurgery with the complex multidisciplinary care that defines modern transplantation medicine. As recent work has provided a more complete picture of the complexities of the psychosocial factors in RHT, a psychosocial assessment protocol developed with input across the centers currently performing this procedure would capitalize on the collective diverse clinical experiences and standardize the assessment and follow-up protocol. With such standardized procedures in place, psychosocial risk factors for both poor psychosocial and medical/surgical outcomes can be identified which can inform the selection or preparation of future candidates.

Abstract
The Louisville VCA (Vascularized Composite Allograft) Program is one of the largest hand transplant programs in the world. During my hand surgery fellowship at the Christine M. Kleinert Institute, the team performed the eighth hand transplant on the seventh recipient in Louisville. The Louisville VCA Program has done 9 hand transplants in 8 recipients with one bilateral case. Among these are the first 5 hand transplant cases in the United States. The first case was done in 1999 and has the World's longest follow-up. The seventh case was performed in a 36-year-old male on July 10, 2011. The result achieved so far can be considered excellent with a very good patient satisfaction. There is a large multidisciplinary team involved in such procedures with all members playing a crucial role for the achievement of the best result possible. The present paper focuses on the surgical procedure for the seventh recipient, which was unique due to the level of amputation of the recipient's hand, with preservation of nerve to the thumb.

Abstract
There have been more than 90 hand and upper extremity transplants performed worldwide. Functional and sensory outcomes have been reported in several studies, but little is known about the psychosocial outcomes. A comprehensive systematic literature review was performed, addressing the psychosocial impact of reconstructive hand transplantation. This review provides an overview of psychosocial evaluation protocols and identifies standards in this novel and exciting field. Essentials of the psychosocial assessment are discussed and a new protocol, the 'Chauvet Protocol', representing a standardized assessment protocol for future multicenter psychosocial trials is being introduced.

Abstract
PURPOSE As reconstructive transplantation emerges as an increasingly viable option for upper limb amputees, a better understanding of quality of life (QOL) outcomes is needed to evaluate the benefits and risks of the procedure from the patient perspective. METHODS To address this need, we searched PubMed (1998-2011) to characterize QOL outcomes among upper limb transplant recipients. We identified 27 articles reporting on QOL outcomes in hand transplantation. Common instruments to assess domains of QOL in hand transplantation include the Disabilities of the Arm, Shoulder, and Hand questionnaire, the Medical Outcomes Study Short Form-36, and the International Registry on Hand and Composite Tissue Transplantation's Hand Transplantation Score System. RESULTS Preliminary reports using standardized measures indicate that most hand transplant recipients described improved QOL. Several studies also qualitatively reported that recipients expressed satisfaction with cosmetic, sensory, functional, and social outcomes after transplantation. However, our review suggests that the measurement of QOL in hand transplantation is limited, although it is largely driven by QOL considerations. CONCLUSIONS This review highlights the need for improved measurement of QOL in hand transplantation. The preliminary QOL findings across published hand transplantation articles will aid in improving the future assessment of QOL in hand transplantation. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic III.

Abstract
The aim of this work is to compare disabilities of the upper limb before and after hand allograft transplantation (HAT), and to describe the side effects of immunosuppressive (IS) agents given to recipients of hand allografts. Clinical cases of HAT published between 1999 and 2011 in English, French, or German were reviewed systematically, with emphasis on comparing disabilities of the arm, shoulder and hand (DASH) scores before and after transplantation. Duration of ischemia, extent of amputation, and time since amputation were evaluated for their effect on intrinsic musculature function. Infectious, metabolic, and oncological complications because of IS therapy were recorded. Twenty-eight patients were reported in 56 clinical manuscripts. Among these patients, disabilities of the upper limb dropped by a mean of 27.6 (±19.04) points on the DASH score after HAT (P = 0.005). Lower DASH scores (P = 0.036) were recorded after secondary surgery on hand allografts. The presence of intrinsic muscle function was observed in 57% of the recipients. Duration of ischemia, extent of transplantation, and time since amputation were not associated statistically with the return of intrinsic musculature function. Three grafts were lost to follow-up because of noncompliance with immunosuppression, rejection, and arterial thrombosis, respectively. Fifty-two complications caused by IS agents were reported, and they were successfully managed medically or surgically. HAT recipients showed notable functional gains, but most complications resulted from the IS protocols.

Abstract
Bilateral forearm and hand transplantation poses unique challenges especially in the setting of bilateral lower limb amputations. A 57-yr-old man with bilateral transradial amputations and bilateral transtibial amputations after remote streptococcal sepsis was admitted for inpatient rehabilitation because of severe debilitation after forearm/hand transplantations. He required 6 wks of bed rest to allow the healing of the allografts but developed profound deconditioning. Because of weight-bearing precautions and other complications such as femoral neurapraxia, he required the use of body weight-support apparatus to ambulate with lower limb prostheses, keeping weight off the allografts. He progressed to walking 600 ft using a platform-wheeled walker at a modified independent level, to climbing four stairs with minimal assistance, and to being able to toss a small football using his right hand, indicating improved flexor function in this hand. Tacrolimus levels were maintained without clinical evidence of acute rejection. Through an individualized therapy regimen, careful monitoring of the allografts and dedicated support staff, rehabilitation training of a previous quadrimembral amputee after bilateral hand transplantations can be successful.

Abstract
Hand transplantation is the most common form of modern composite tissue allotransplantation. Successful application of this technology requires a multidisciplinary approach incorporating not only skilled hand surgeons, transplant surgeons, and transplant immunologists, but also hand therapists, psychiatrists, medical specialists, anesthesiologists, and others. Functional outcomes can be life changing for properly selected candidates. Hand transplantation is becoming more common, with more centers offering this relatively new reconstructive modality. Its success depends on proper patient selection, a technically successful operation, postoperative rehabilitation, and an immunotherapy protocol that prevents rejection but has minimal or acceptable morbidity.

Abstract
Patients who have lost a hand or upper extremity face many challenges in everyday life. For some patients, reconstructive hand transplantation represents a reasonable option for anatomic reconstruction, restoring prehensile function with sensation and allowing them to regain daily living independence. The first clinical case of bilateral hand transplantation at University Hospital Innsbruck was realized on March 17th, 2000. A decade later, a total of 7 hands and forearms were transplanted in 4 patients. This article review the clinical courses of 3 bilateral hand transplant recipients and highlights psychological aspects on reconstructive hand transplantation with special regard to unilateral/bilateral transplantation.

Abstract
The ultimate goal of hand allotransplantation is to achieve graft survival and useful long-term function. To achieve these goals, selection of the appropriate patient, detailed preoperative planning, and precise surgical technique are of paramount importance. Transplantation should be reserved for motivated consenting adults in good general heath, who are psychologically stable and have failed a trial of prosthetic use. While the key surgical steps of transplantation are similar to those of replantation, there are major differences. This article describes the steps in hand allotransplantation, and the importance of patient selection as well as preoperative and postoperative care.

Abstract
To date, 78 upper extremity transplants have been performed in 55 recipients around the world. The purpose of this article is to provide an overview of acute and chronic rejection (CR) and to summarize collective insights in upper extremity transplantation. To date, almost all patients experienced AR that is pathophysiologically similar to that in solid organs. The spectre of chronic rejection is just emerging. Upper extremity transplantation has significant potential as a reconstructive option only if efforts are invested in strategies to reduce risks of prolonged immunosuppression and in approaches to better diagnose, monitor and treat AR and CR.

Abstract
This article summarizes the findings from 3 recipients of hand allografts, including a description of the preparatory surgery and the transplant and secondary procedures to enhance the function of the hand, forearm, and arm allografts. The study focuses on the complications and disability reported by each patient, with a minimum follow-up of 2 years. The few complications were controlled successfully with medical treatment. Hand transplantation is a major reconstructive procedure that requires careful medical follow-up. The authors provide the first report of a significant improvement in disabilities of the upper limb as a result of hand allotransplantation.

Abstract
Mild skin rejection is a common observation in reconstructive transplantation. To enlighten the role of this inflammatory reaction we investigated markers for cellular and antibody mediated rejection, adhesion molecules and tolerance markers. Forty-seven skin biopsies (rejection grade I) of human hand allografts were investigated by immunohistochemistry (CD3, CD4, CD8, CD20, CD68, C4d, LFA-1, ICAM-1, E-selectin, P-selectin, VE-cadherin, HLA-DR, IDO, and Foxp3). Expression was read with respect to time after transplant. The infiltrate was mainly comprised of CD3+T-lymphocytes. Among these, CD8+cells were more prominent than CD4+cells. CD20+B-lymphocytes were sparse and CD68+macrophages were found in some, but not all samples (approximately 10% of the infiltrate). The CD4/CD8-ratio was increased after the first year. C4d staining was mainly positive in samples at time-points later than 1 year. Adhesion molecules LFA-1, ICAM-1, E-selectin, P-selectin, and VE-cadherin were found upregulated, and for P-selectin, expression increased with time after transplant. IDO expression was strongest at 3 months-1 year post-transplant and a tendency toward more Foxp3+ cells at later time points was observed. Mild skin rejection after hand transplantation presents with a T-cell dominated dermal cell infiltrate and upregulation of adhesion molecules. The role of C4d expression after year one remains to be elucidated.

Abstract
Overall, more than 60 hand/forearm/arm transplantations and 16 face transplantations have been performed in the past 12 years. In the European experience summarized here, three grafts have been lost in response to a vascular thrombosis (n = 1), rejection and incompliance with immunosuppression (n = 1) and death (n = 1). The overall functional and esthetic outcome is very satisfactory, but serious side effects and complications related to immunosuppression are challenges hindering progress in this field. The high levels of immunosuppression, skin rejection, nerve regeneration, donor legislation and the acceptance level need to be addressed to promote growth of this promising new field in transplantation and reconstructive surgery.

Abstract
Skin rejection remains a major hurdle in reconstructive transplantation. We investigated molecular markers of skin rejection with particular attention to lymphocyte trafficking. Skin biopsies (n = 174) from five human hand transplant recipients were analyzed for rejection, characteristics of the infiltrate and lymphocytic adhesion markers. The cellular infiltrate predominantly comprised CD3+ T cells. CD68, Foxp3 and indoleamine 2, 3-dioxygenase expression and the CD4/CD8 increased with severity of rejection. Lymphocyte adhesion markers were upregulated upon rejection, intercellular adhesion molecule-1 and E-selectin correlated best with severity of rejection. Guided by the findings, a specific E- and P-selectin inhibitor was investigated for its effect on skin rejection in a rat hind limb allotransplant model. While efomycine M (weekly s.c. injection into the graft) alone had no effect, long-term allograft survival was achieved when combined with antithymocyte globulin and tacrolimus (control group without efomycine M rejected at postoperative day [POD] 61 +/- 1). Upregulation of lymphocyte trafficking markers correlates with severity of skin rejection and time after transplantation in human hand transplantation. Blocking E- and P-selectin in the skin holds potential to significantly prolong limb allograft survival.
