Quality of Life after Face Transplantation: Outcomes, Assessment Tools, and Future Directions.

Background: Face transplantation has emerged as a clinical reality for the restoration of complex facial defects. Critical to the advancement of the burgeoning field of reconstructive transplantation is the quality of the methods used to measure and report the impact of face transplantation on quality of life. Methods: A systematic search using PubMed and EMBASE was conducted for all studies matching the a priori inclusion criteria from 2005 through 2015. Bibliographies of included studies were also reviewed. Two authors (M.A.A and H.K) independently performed screening of titles. Results: The authors identified 17 articles reporting on quality-of-life outcomes among 14 face transplant recipients. Combinations of objective and subjective measures were used to assess quality of life. Instruments used to assess quality of life after face transplantation included over 25 different instruments. Four centers, comprising eight patients, have reported using prospective, systematic data with validated instruments. Overall, there is reported improvement in quality of life after face transplantation. Heterogeneity and a paucity of data between articles preclude a quantitative analysis. Conclusions: Anecdotal and subjective reports of improvements in quality of life after face transplantation constitute the majority of reported outcomes in the English peer-reviewed literature. Improved efforts in methods and standardization of collection and reporting of quality-of-life data after face transplantation are needed to better appreciate the impact of face transplantation on quality of life and justify lifelong immunosuppression and its attendant risks and morbidity.

Mental Status in Patients Before and After Liver Transplantation

BACKGROUND In contrast to the well-described beneficial organic effects of liver transplantation (OLT) in patients with end-stage liver disease, changes in the mental status of patients after OLT remain poorly understood. The current study seeks to evaluate the influence of OLT on anxiety, depression, and dispositional optimism in patients with end-stage liver disease. MATERIAL AND METHODS Questionnaires were sent to patients on the OLT waiting list and patients after OLT. Depression/anxiety and dispositional optimism were assessed using the HADS and LOT-R questionnaires, respectively. These findings were compared to results from the general population. RESULTS The number of returned questionnaires was 292 of 940 (31.1%; 57 patients on the liver transplant waiting list: waiting group, 235 liver transplant recipients: OLT group). Both depression and anxiety scores were significantly higher in the waiting group when compared to the OLT group (p<0.05) and the general population (anxiety: p<0.001, depression: p<0.05), respectively. The OLT group was characterized by significantly higher anxiety scores (p<0.001) compared to the general population. Depression and summation scores did not differ (p>0.05). Dispositional optimism was higher in the OLT group compared to the waiting group (p<0.05) and to the general population (p<0.01). The waiting group had equal values as the general population (p>0.05). CONCLUSIONS Besides beneficial effects on liver function, OLT appears to be associated with significant improvements in depression and anxiety and a more optimistic view of life.

Acellular Hypothermic Extracorporeal Perfusion Extends Allowable Ischemia Time in a Porcine Whole Limb Replantation Model

Background: One of the major challenges in traumatic amputation is the need to keep ischemia time brief (4 to 6 hours) to avoid ischemic damage and enable successful replantation. The current inability to meet this challenge often leads to traumatic limb loss, which has a considerable detrimental impact on the quality of life of patients. Methods: The authors’ team built a portable extracorporeal membrane oxygenator device for the perfusion of amputated extremities with oxygenated acellular solution under controlled parameters. The authors amputated forelimbs of Yorkshire pigs, perfused them ex vivo with acellular Perfadex solution for 12 hours at 10°C in their device, and subsequently replanted them into the host animal. The authors used limbs stored on ice slurry for 4 hours before replantation as their control group. Results: Clinical observation and histopathologic evaluation both demonstrated that there was less morbidity and less tissue damage to the cells during preservation and after replantation in the perfusion group compared with the standard of care. Significant differences in blood markers of muscle damage and tissue cytokine levels underscored these findings. Conclusions: The authors demonstrated the feasibility and superiority of ex vivo hypothermic oxygenated machine perfusion for preservation of amputated limbs over conventional static cold storage and herewith a substantial extension of the allowable ischemia time for replantation after traumatic amputation. This approach could also be applied to the field of transplantation, expanding the potential pool of viable donor vascularized composite allografts.

Evaluation of Complication Rates after Breast Surgery Using Acellular Dermal Matrix: Median Follow-Up of Three Years

Introduction Acellular dermal matrices (ADMs) are now commonly used for breast reconstruction surgery. There are various products available: ADMs derived from human (HADM), porcine (PADM), or bovine (BADM) sources. Detailed long-term follow-up studies are necessary to detect differences in complication rates between these products. Material and Methods From 2010 to 2015, forty-one patients underwent 52 ADM-breast reconstructions in our clinic, including oncologic breast reconstructions and breast augmentation revisions (n = 52). 15x HADMs (Epiflex®/DIZG), 21x PADMs (Strattice®/LifeCell), and 16x BADMs (Tutomesh®/RTI Surgical) were implanted. Retrospective data collection with median follow-up of 36 months (range: 12–54 months) was performed. Results Overall complication rate was 17% after ADM implantation (HADM: 7%; PADM: 14%; BADM: 31%). In a composite endpoint of complications and Red Breast Syndrome, a lower event probability was observed between BADMs, PADMs, and HADMs (44%, 19%, and 7%, resp.; p = 0.01 for the trend). Furthermore, capsular contracture occurred in 6%, more frequently as compared to the current literature. Conclusions When ADM-based reconstruction is indicated, the authors suggest primarily the use of HADMs and secondary the use of PADMs. It is shown that BADMs have the highest complication probability within our patient cohort; nevertheless, BADMs convey physical advantages in terms of flexibility and better aesthetic outcomes. The indication for the use of ADMs should be filled for each case individually.

The role of face transplantation in the self-inflicted gunshot wound

BACKGROUND Facial self-inflicted gunshot wounds (SIGSWs) cause a devastating midfacial defect and pose a challenging problem to the reconstructive surgeon. Face transplantation (FT) has the potential for near-normal restoration in otherwise non-reconstructible defects. Two out of 7 FT recipients at Brigham and Womens Hospital (BWH) sustained SIGSWs. In this study, we illustrate the role of FT in the management of SIGSWs through an aesthetic, functional, and psychosocial examination of outcomes. METHODS We performed a retrospective analysis of individuals with SIGSWs who were screened at BWH between 2008 and 2015. We then collected data of the injuries, modes of conventional reconstruction (CR), and deficits. For the FT recipients, we critically reviewed the psychosocial screening process and post-transplantation aesthetic, functional, and psychosocial outcomes. RESULTS A total of six individuals post-SIGSWs were screened for FT. All of them had undergone CR, with five receiving loco-regional flaps and free tissue transfers, and one undergoing serial debridement and primary soft-tissue repair. Following CR, all suffered from residual functional and aesthetic deficits. Two underwent partial FT and one is currently undergoing FT screening. We describe the pre-transplant psychosocial screening process and the aesthetic, functional, and psychosocial outcomes of the SIGSW FT recipients. CONCLUSIONS We examined the facial SIGSW injury, outcomes of CR, and the mechanism of FT to offer a potential solution to the shortcomings of CR. More importantly, we highlight the critical nature of the psychosocial component of the multidisciplinary evaluation given the history of mental illness and suicidal behavior in this subset of patients.

Immunological Characteristics of a Patient With Belatacept‐Resistant Acute Rejection After Face Transplantation

Belatacept has been introduced as a promising novel immunosuppressant to the field of transplantation, especially for patients suffering from adverse effects of conventional immunosuppression such as nephrotoxicity. Analysis of rejection episodes under costimulation-based regimen in kidney transplants suggested that high percentages of circulating CD4+CD57+PD1- cells pre-transplantation may be predictive markers for belatacept-resistant acute rejection (BRR) (1). We investigated this particular subset in one of our face transplant recipients who experienced complications of CNI-based immunosuppression. This article is protected by copyright.

A Retrospective Analysis of Secondary Revisions after Face Transplantation: Assessment of Outcomes, Safety, and Feasibility

Background: Face transplantation has emerged as a viable option for certain patients in the treatment of devastating facial injuries. However, as with autologous free tissue transfer, the need for secondary revisions in face transplantation also exists. The authors’ group has quantified the number of revision operations in their cohort and has assessed the rationale, safety, and outcomes of posttransplantation revisions. Methods: A retrospective analysis of prospectively collected data of the authors’ seven face transplants was performed from April of 2009 to July of 2015. The patients’ medical records, preoperative facial defects, and all operative reports (index and secondary revisions) were critically reviewed. Results: The average number of revision procedures was 2.6 per patient (range, zero to five procedures). The median time interval from face transplantation to revision surgery was 5 months (range, 1 to 10 months). Most interventions consisted of debulking of the allograft, superficial musculoaponeurotic system plication and suspension, and local tissue rearrangement. There were no major infections, allograft skin flap loss, or necrosis. One patient suffered a postoperative complication after autologous fat grafting in the form of acute rejection that resolved with pulse steroids. Conclusions: Secondary revisions after face transplantation are necessary components of care, as they are after most conventional free tissue transfers. Secondary revisions after face transplantation at the authors’ institution have addressed both aesthetic and functional reconstructive needs, and these procedures have proven to be safe in the context of maintenance immunosuppression. Patient and procedure selection along with timing are essential to ensure patient safety, optimal function, and aesthetic outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

Impact of different immunosuppressive regimens on the health‐related quality of life following orthotopic liver transplantation

The influence of immunosuppression on the recipients’ quality of life (QoL) is of major importance after OLT and has not yet been evaluated.

Face transplantation-current status and future developments

More than thirty‐five facial allograft transplantations (FAT) have been reported worldwide since the pioneering case performed in France in the year 2005. FAT has received tremendous interest by the medical field and the general public while gaining strong support from multiple disciplines as a solution for reconstructing complex facial defects not amenable/responsive to conventional methods. FAT has expanded the frontiers of reconstructive microsurgery, immunology and transplantation, and established its place in the cross section of multiple disciplines. The procedure introduces complex scientific, ethical, and societal issues. Patients and physicians are called to deal with a variety of—sometimes everlasting—challenges, such as immunosuppression management and psychosocial hurdles. This review reflects on the surgical and scientific advancements in FAT and milestones reached in the last 12 years. It aims to encourage active discussion regarding the current practices and techniques used in FAT and suggest future directions that may allow transitioning into the next phase of FAT, which we describe as safe, reliable, and accessible standard operation for selected patients.

Trendy Tattoos—Maybe a Serious Health Risk?

BackgroundThe literature reports many cases of cutaneous malignancy in the setting of skin tattoos. In this study, we review the reported incidence of and risk factors for tattoo-associated skin cancer.MethodsA PubMed literature review was performed for all cases of tattoo-associated skin cancer, including squamous cell carcinoma, basal cell carcinoma, malignant melanoma, keratoacanthoma, and other rare skin malignancies (source: PubMed/until June 2017).ResultsThe authors identified 51 publications and 63 total cases of tattoo-associated skin cancer. We also report on a single new case of tattoo-associated skin cancer observed at one of our co-authors’ institutions. Among these 64 total cases, 58% were associated with black and blue inks and 34% were associated with red ink.ConclusionsOverall, while the strength of association remains unclear, the literature reports many cases of tattoo-associated skin cancer. Among these cases, black, blue, and red inks were particularly worrisome for their carcinogenic potential.Level of Evidence IVThis journal requires that authors assign a level of evidence to each article.
