Free Tissue Transfer for Reconstruction After Bilateral Skin Sparing Mastectomy-A Systematic Review.

BACKGROUND: Breast cancer is the most commonly diagnosed malignant neoplasia in females worldwide. Overall survival and patients' choice for bilateral mastectomy have increased. It is therefore important to offer breast reconstructive procedures to improve patient quality of life and self-esteem. The aim of this systematic literature review is to quantify the outcome and sustainability of bilateral breast reconstruction using autologous, vascularized free tissue transfer. METHODS: A systematic literature review of PubMed, Cochrane, and the Web of Science databases was performed. A total of 5879 citations were identified, and 12 studies met the inclusion criteria. RESULTS: A total of 1316 patients were included, with a mean age of 47.2 years. Overall, 32.5% of patients experienced a complication after breast reconstruction. If reported, 7.45% of patients experienced major complications, while 20.7% had minor complications.The following flaps were used for breast reconstruction, in order of reducing frequency: DIEP (45.45%), TRAM (22.73%), SIEA (9.09%), SGAP (9.09%), TUG (4.55%), TMG (4.55%), and LD/MLD (4.55%). CONCLUSIONS: Current studies indicate that bilateral breast reconstruction using autologous, vascularized free tissue transfer is a safe procedure for postmastectomy reconstruction and offers stable long-term results. This is particularly in comparison to implant-based breast reconstruction.

Organization of Hannover Skin Bank: Sterile culture and procurement protocols for viable cryopreserved allogeneic skin grafts of living donors.

Preserved allogeneic donor skin still represents one of the gold standard therapies in temporary wound coverage in severely burned patients or chronic wounds. Allogeneic skin grafts are currently commercially available as cryo- or glycerol-preserved allografts through skin tissue banks all over the world. Most of the skin tissue banks rely on human cadaveric skin donations. Due to the chronic shortage of human allogeneic transplants, such as skin, and increasing costs in the procurement of allografts from other skin tissue banks, Hannover Medical School has been building up its own skin tissue bank based on allogeneic skin grafts from living donors who underwent surgical treatment (i.e., body-contouring procedures, such as abdominioplasties). This article presents procedures and protocols for the procurement and processing of allogeneic skin grafts according to national legislation and European regulations and guidelines. Beside protocols, initial microbiological data regarding the sterility of the harvested grafts are presented. The results currently form the basis for further investigations as well as clinical applications. In summary, a microbiological testing and acceptance procedure is presented that ensures adequate patient safety and skin viability.

Consequences and predisposing factors of self-discharge against medical advice in plastic and hand surgery.

PURPOSE: Therapeutic success of surgical interventions is significantly affected by patients' adherence. Patient autonomy can lead to unreasonable behavior. We analyzed the consequences and predisposing factors of patient self-discharge in a plastic and hand surgery cohort. STUDY DESIGN AND SETTING: Data was collected retrospectively in a case-control study with n = 73 patients who had self-discharged in a 10-year time period and n = 130 controls (discharge by the surgeon). Data was collected through the hospital information systems and a particular questionnaire. Statistical analyses were performed via chi-squared test and logistic regression analyses. RESULTS: Patients who self-discharged against medical advice had a significantly higher complication rate (p = 0.045) and a higher number of revision operations (p < 0.001). They were more often dissatisfied with the primary inpatient treatment (p < 0.05). Secondly, they lived more often in shared households (p = 0.002; OR 5.387 (1.734-16.732)) or had to take care of their children at home (p = 0.006; OR 1.481 (1.280-1.741)). There was a significantly lower pain score (NAS) on time of self-discharge (p = 0.002) as well as 24 h after self-discharge (p < 0.001) in self-discharged patients. CONCLUSION: Self-discharge was associated with predisposing factors and poorer outcomes. Patient autonomy can lead to health-compromising behavior and patients should be counseled accordingly.

Complications and Disasters After Minimally Invasive Tissue Augmentation with Different Types of Fillers: A Retrospective Analysis.

BACKGROUND: The interest in youthful appearance and rejuvenating procedures is unbroken in our society. Besides surgical procedures, permanent fillers are utilized. The incorrect and unprofessional use of these substances, auto-injections in particular, have devastating results for patients and are challenging for the plastic surgeon. The aim of this retrospective study was to delineate the differences between permanent and non-permanent filler complications and appropriate treatment options. METHODS: We conducted a retrospective study and researched the hospital information system in the time period from 2001 to 2020. Patients with unprofessional use of permanent fillers, auto-injections and injections of unformulated substances were determined. Age, gender, localization, complications, length of hospital stay, comorbidities, histopathological workups and surgical salvage procedures were noted. Descriptive statistics were calculated. RESULTS: Seventeen patients were identified from 2001 till 2020. In four cases, auto-injections by the patients were the cause, whereas in the other patients the injections were performed by medical staff. Ages range from 18 to 57 years. Fourteen patients were female and three were male. The injected substances could be recognized as synthol, silicone, vaseline, fat tissue, hyaluronic acid as well as non-medical substances. Surgical procedures were necessary in eleven cases. One patient died because of the underlying diseases. CONCLUSION: Our results indicate different sequels of filler materials injected in an unprofessional way, possible complications, conservative and surgical techniques to resolve these rare complications. We suggest a staged therapy adjusted to the clinical symptoms. Milder symptoms can be handled conservatively, whereas severe infections, skin breakdowns or persistent granuloma are justifying indications for surgical treatment.

[Infections of the hand and forearm]. / Infektionen der Hand und des Unterarms.

Infections of the hand and forearm are a frequently seen surgical emergency of the hand. Patients of all age groups are affected and underlying systemic diseases are risk factors. Posttraumatic causes are the leading cause of infections. This includes cuts and stab wounds, animal and human bites but often also minor injuries. Due to the anatomical peculiarities of the hand, rapid progression of initially inconspicuous infections can occur resulting in functional limitations. If an infection is suspected, a symptom-oriented evaluation by a hand surgeon should be performed. This includes a detailed patient history, clinical examination, laboratory analyses and imaging. This is followed by the development of an individualized and interdisciplinary treatment concept with the aim of achieving the shortest possible rehabilitation period. The treatment includes surgical cleansing of the infection, accompanied by antibiotic treatment taking the expected possible spectrum of pathogens into account. Cephalosporins and aminopenicillins in combination with beta-lactamase inhibitors are the antibiotics of first choice. Follow-up treatment includes early functional exercise under the guidance of a hand therapist to minimize postinfectious restrictions in the range of motion and to enable occupational rehabilitation. In rare cases, fulminant necrotizing infections with resulting skin and soft tissue defects can occur. In these cases, secondary plastic reconstruction is usually required after cleansing of the infection.

The surgical approach to Pyoderma gangrenosum: A retrospective monocenter study.

Pyoderma gangrenosum is a diagnosis of exclusion. It occurs rarely and is frequently misdiagnosed. It can result in severe tissue loss, particularly in surgical units with little experience. Nevertheless, surgical treatment might be necessary for reconstruction, once the progression of these wounds is controlled. We aimed to characterize medical findings in Pyoderma patients with extensive defects to assess the surgical procedures and their outcome. A retrospective study was conducted at our centre over an 18-year period. Inclusion criteria were the diagnosis of Pyoderma gangrenosum and at least one surgical intervention. Descriptive statistics were used to analyse the data. Sixteen patients were included. The mean size of the lesions was noted with 12 × 8 cm. Surgical procedures comprised debridements/necrectomies, allograft conditioning, negative pressure wound therapy, skin grafts, and microvascular free flaps. Seven patients were discharged with healed wounds, six with minor wound healing disturbances. Three patients succumbed to their underlying diseases. Drug-based therapy can stop the progress of Pyoderma, but severe tissue loss can be a persistent problem. According to our data, reconstructive-surgical treatments (debridement, autologous and allogenous skin transplantation and microvascular free flaps) act as an integral component of the therapy and can be safe options for selected patients. Furthermore, we provide an algorithm that we follow at our department in severe cases.

Botulinum Toxin Versus Placebo: A Meta-Analysis of Treatment and Quality-of-life Outcomes for Hyperhidrosis.

AIMS: This study aims at assessing the treatment effect, disease severity and quality-of-life outcomes of botulinum toxin (BTX) injections for focal hyperhidrosis. METHODS: We included randomized controlled trials of BTX injections compared with placebo for patients with primary or secondary focal hyperhidrosis. PubMed, Embase and the Cochrane Library were searched to August 2020. Gravimetric sweat rate reduction, disease severity measured by Hyperhidrosis Disease Severity Scale and quality-of-life assessment measured by Dermatology Life Quality Index were the outcomes of interest. Cochrane risk-of-bias tools were employed for quality assessment of given randomized controlled trials. RESULTS: Eight studies met our inclusion criteria (n=937). Overall, risk bias was mixed and mostly moderate. BTX injections showed reduced risk in comparison with placebo for the gravimetric quantitative sweat reduction of > 50 % from baseline (risk difference: 0.63, 95% CI 0.51 to 0.74). Additionally, improvements were seen for disease severity and quality-of-life assessments evaluated by Hyperhidrosis Disease Severity Score reduction of ≥ 2 points (risk difference: 0.56, 95% CI 0.42 to 0.69) and mean change in Dermatology Life Quality Index (mean difference: - 5.55, 95% CI - 7.11 to - 3.98). The acquired data were insufficient to assess for long-term outcomes and limited to an eight-week follow-up period. CONCLUSIONS: In focal axillary hyperhidrosis, BTX significantly reduces sweat production and yields superior outcomes in assessments of disease severity and quality-of-life. However, the quality-of-evidence is overall moderate and included studies account for short-term trial periods only. Further studies assessing BTX in comparison with first-line treatments for hyperhidrosis are warranted.

A Short History of Skin Grafting in Burns: From the Gold Standard of Autologous Skin Grafting to the Possibilities of Allogeneic Skin Grafting with Immunomodulatory Approaches.

Due to groundbreaking and pioneering developments in the last century, significant improvements in the care of burn patients have been achieved. In addition to the still valid therapeutic standard of autologous split-thickness skin grafting, various commercially available skin substitutes are currently available. Significant progress in the field of tissue engineering has led to the development of promising therapeutic approaches. However, scientific advances in the field of allografting and transplant immunology are of great importance. The achievement of various milestones over the past decades has provided thought-provoking impulses in the field of skin allotransplantation. Thus, biologically viable skin allotransplantation is still not a part of the clinical routine. The purpose of this article is to review the achievements in burn surgery with regards to skin allotransplantation in recent years.

Chronic rejection of human face allografts.

Face vascularized composite allografts (FVCAs) have helped patients with severe facial disfigurement, with acute rejection now largely controlled through iatrogenic immunosuppression. However, little is known regarding the incidence and mechanism(s) of more long-term pathologic alterations in FVCAs that may affect function and graft durability. Protocol surveillance biopsy specimens for up to an 8-year interval in 7 patients who received FVCAs at our institution revealed histopathologic evidence of chronic rejection. Clinical manifestations included features of premature aging, mottled leukoderma accentuating suture lines, telangiectasia, and dryness of nasal mucosa. Pathologic changes consisted of epidermal thinning accompanied by discrete foci of lymphocyte-mediated cytotoxicity, hyperkeratosis, follicular plugging, vascular ectasia, and sclerosis beneath the epidermal layer associated with collagen type I deposition. Genomic interrogation and immunohistochemistry of sclerotic zones revealed upregulation of the AP-1 pathway components, JunB and c-Fos, previously implicated in overproduction of type I dermal collagen in the setting of systemic sclerosis. We conclude that some patients develop chronic rejection in FVCAs with striking similarities to alterations seen in certain autoimmune cutaneous disorders (lupus erythematosus and scleroderma/chronic sclerodermoid graft-versus-host disease). Identification of relevant pathways and genes, such as JunB and c-Fos, may provide new targets for preventative therapies for chronic immune-mediated changes in vascularized composite allografts.

Reduced Hypoxia-Related Genes in Porcine Limbs in Ex Vivo Hypothermic Perfusion Versus Cold Storage.

BACKGROUND: Ischemia-reperfusion injury remains the major limiting factor for limb replantation and transplantation. Static cold storage (SCS) on ice currently represents the standard mode of preservation but is limited to 6 h of duration. Ex vivo machine perfusion has evolved as a potential alternative to safely extend the duration of ex vivo preservation by providing continuous supply of oxygen and nutrients. This study aims to evaluate underlying molecular mechanisms of both preservation modalities. METHODS: We assessed molecular changes in amputated porcine forelimbs stored on ice at 4°C for 2 h (n = 2) and limbs perfused with Perfadex solution at 10°C for 2 h (n = 3) or 12 h (n = 3) before replantation. Muscle biopsies were examined for histological changes and gene expression levels using H&E staining and a hypoxia-related PCR gene array, respectively. RESULTS: Histology revealed only minor differences between the ice (SCS) and perfusion groups after 2 h of preservation, with decreased muscle fiber disruption in the perfusion groups compared with the ice (SCS) group. Perfused limbs demonstrated downregulation of genes coding for glycolytic pathways and glucose transporters after 2 h and 12 h when compared with SCS after 2 h. Similarly, genes that induce angiogenesis and those that are activated on DNA damage were downregulated in both perfusion groups as compared with SCS. CONCLUSIONS: Perfusion of porcine limbs resulted in less activation of hypoxia-related gene families when compared with SCS. This may indicate a state more closely resembling physiological conditions during perfusion and potentially limiting ischemic injury. Our study confirms ex vivo perfusion for up to 12 h as a viable alternative for preservation of vascularized composite tissues.

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.

Extracorporeal Perfusion in Vascularized Composite Allotransplantation: Current Concepts and Future Prospects.

Severe injuries of the face and limbs remain a major challenge in today's reconstructive surgery. Vascularized composite allotransplantation (VCA) has emerged as a promising approach to restore these defects. Yet, there are major obstacles preventing VCA from broad clinical application. Two key restrictions are (1) the graft's limited possible ischemia time, keeping the potential donor radius extremely small, and (2) the graft's immunogenicity, making extensive lifelong monitoring and immunosuppressive treatment mandatory. Machine perfusion systems have demonstrated clinical success addressing these issues in solid organ transplantation by extending possible ischemia times and decreasing immunogenicity. Despite many recent promising preclinical trials, machine perfusion has not yet been utilized in clinical VCA. This review presents latest perfusion strategies in clinical solid organ transplantation and experimental VCA in light of the specific requirements by the vascularized composite allograft's unique tissue composition. It discusses optimal settings for temperature, oxygenation, and flow types, as well as perfusion solutions and the most promising additives. Moreover, it highlights the implications for the utility of VCA as therapeutic measure in plastic surgery, if machine perfusion can be successfully introduced in a clinical setting.

Trismus in Face Transplantation Following Ballistic Trauma.

BACKGROUND: Trismus can be a challenging consequence of ballistic trauma to the face, and has rarely been described in the setting of face transplantation. Almost half of all current face transplant recipients in the world received transplantation to restore form and function after a ballistic injury. Here we report our experience and challenges with long standing trismus after face transplantation. METHODS: We reviewed the medical records of our face transplant recipients whose indication was ballistic injury. We focused our review on trismus and assessed the pre-, peri- and postoperative planning, surgery and functional outcomes. RESULTS: Two patients received partial face transplantation, including the midface for ballistic trauma. Both patients suffered from impaired mouth opening, speech intelligibility, and oral competence. Severe scarring of the temporomandibular joint (TMJ) required intraoperative release in both patients, and additional total condylectomy on the left side 6 months posttransplant for 1 patient. Posttransplant, both patients achieved an improvement in mouth opening; however, there was persistent trismus. One year after transplantation, range of motion of the jaw had improved for both patients. Independent oral food intake was possible 1 year after surgery, although spillage of liquids and mixed consistency solids persisted. Speech intelligibility testing showed impairments in the immediate postoperative period, with improvement to over 85% for both patients at 1 year posttransplant. CONCLUSIONS: Ballistic trauma to the face and subsequent reconstructive measures can cause significant scarring and covert injuries to structures such as the TMJ, resulting in long standing trismus. Meticulous individual planning prior to interventions such as face transplantation must take these into account. We encourage intraoperative evaluation of these structures as well as peri- and postoperative treatment when necessary. Due to the nature of the primary injury, functional outcomes after face transplantation in these patients may differ substantially from those of other indications.

Trendy Tattoos-Maybe a Serious Health Risk?

BACKGROUND: The 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. METHODS: A 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). RESULTS: The 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. CONCLUSIONS: Overall, 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.

Primary liver transplantation and liver retransplantation: comparison of health-related quality of life and mental status - a cross-sectional study.

BACKGROUND: Liver Retransplantation (Re-LT) procedures are associated with an increased risk of morbidity and mortality. Up to date, there is no knowledge on the health-related quality of life and the mental status of these patients. METHODS: Health-Related Quality of Life (HRQoL) was assessed by using the Short Form 36 (SF-36) Health Survey and Mental Status was assessed by using the Hospital Anxiety and Depression Scale (HADS). The patients were examined in different assessments: During regular check-up examinations in the LT outpatient department in 2011 (Survey 1) and in a postal survey in 2013 (Survey 2). Their medical data was collected by using an established database. RESULTS: We received eligible surveys of 383 patients (55.6%) with a history of LT, of which 15 (3.9%) had undergone Re-LT (Re-LT group). These patients were compared to a group of 60 patients who had undergone only one LT. With regard to their HRQoL, the Re-LT group had significantly lower scores on the scales of physical function (PF, p = 0.026), their role-physical (RP, p = 0.008), their vitality (VIT, p = 0.040), and their role-emotional (RE, p = 0.005). The scores for anxiety and depression did not differ significantly between the groups. In a multiple regression analysis, chronic kidney disease was found to be an independent risk factor for decreased scores of PF (p = 0.023). CONCLUSIONS: Patients who have to undergo Re-LT procedures are faceing impairments in physical aspects of a HRQoL. Together with clinical results from other studies, the findings of the present examination underline the need for an optimized organ distribution strategy since not all patients listed for Re-LT appear to benefit from it.

The elderly liver transplant recipients: anxiety, depression, fatigue and life satisfaction.

Introduction Older patients are neglected in clinical trials and are likely to be excluded from liver transplantation (LT). The aim of this study was to assess fatigue, anxiety, depression, and health-related quality of life (HRQoL) in elderly LT recipients. Methods Questionnaires were mailed to patients who underwent LT between 1993 and 2013. Three groups were created: patients ≥ 70, 60 - 69, and < 60 years old. Mental-health status, life satisfaction, and fatigue were assessed using, respectively, the Hospital Anxiety and Depression Scale (HADS), Questions on Life Satisfaction (FLZ-M), and the Multidimensional Fatigue Inventory (MFI-20). Results In total, 276 eligible questionnaires (40.1 %) were received out of 689 patients with a history of LT. No age-related differences were found with regard to anxiety or depression in the study sample. Patients ≥ 70 years old had significantly better life satisfaction in regards to income (p = 0.003) and work (p = 0.005) compared to patients < 60 years. The overall fatigue scores were the highest in patients < 60 years (52.7, SD = 15.8) and ≥ 70 years (52.7, SD = 17.7) compared to patients 60 - 69 years old (48.2, SD = 17.3, p = 0.037). Discussion Advanced age alone should not be considered a contraindication for LT due to potentially poor quality of life outcomes.

Optimal Positioning of the Nipple-Areola Complex in Men Using the Mohrenheim-Estimated-Tangential-Tracking-Line (METT-Line): An Intuitive Approach.

INTRODUCTION: The reconstruction of the body shape after post-bariatric surgery or high-grade gynecomastia involves, besides skin tightening, the repositioning of anatomical, apparent landmarks. The surgeon usually defines these during the preoperative planning. In particular, the positions of the nipple-areola complexes (NAC) should contribute to the gender-appropriate appearance. While in the female breast numerous methods have been developed to determine the optimal position of the NACs, there are only a few, metric and often impractical algorithms for positioning the nipples and areoles in the male. With this study, we show the accuracy of the intuitive positioning of the nipple-areola complex in men. MATERIAL AND METHODS: From a pre-examined and measured quantity of 10 young and healthy men, six subjects were selected, which corresponded, on the basis of their chest and trunk dimensions, to the average of known data from the literature. The photographed frontal views were retouched in two steps. Initially, only the NACs were removed and the chest contours were left. In a second step, all contours and the navel were blurred. These pictures were submitted to resident and consultant plastic surgeons, who were asked to draw the missing NACs without any tools. The original positions of the nipples were compared with the inscriptions. Furthermore, the results were compared between the contoured and completely retouched pictures and between the residents and consultants. RESULTS: A total of 8 consultants and 7 residents were included. In the contoured and completely retouched images, a significant deviation of the marked positions of the missing features was found. The height of the NAC was determined somewhat more precisely than the vertical position. There was no significant difference between the contoured and completely retouched images, with a discretely more accurate tendency on the contoured images. In comparison with the professional experience, the consultants were tangentially more precise, but without a statistically significant impact. DISCUSSION: The intuitive determination of the NACs is a challenge for the plastic surgeon. In this study, a statistically significant deviation was seen in almost all dimensions, although the clinical relevance cannot be conclusively assessed. We found a positional relationship of the NAC to the infraclavicular groove ("Mohrenheim pit") in the vertical and 4-4.5 cm above the submammary fold. The position of the NAC can be satisfactorily determined by a combination of plastic surgical intuition, patient wishes and practical metric methods using the Mohrenheim-Estimated-Tangential-Tracking-Line (METT-Line).

Health-related quality of life and affective status in liver transplant recipients and patients on the waiting list with low MELD scores.

BACKGROUND: This study seeks to examine the impact of orthotopic liver transplantation (OLT) on Health-Related Quality of Life (HRQoL) and mental health in patients with different MELD scores. METHODS: Patients who has undergone orthotopic liver transplant (OLT) or were on the waiting list for OLT were submitted to HRQoL and depression/anxiety assessment by questionnaire: Short-Form 36 (SF-36), Questions on Life Satisfaction (FLZ-M), Patient Health Questionnaire-4 (PHQ-4). Data were analysed following division of patients into three groups: pretransplant patients with a MELD score <10, ≥10, and OLT recipients. RESULTS: The surveys were sent to 940 consecutive patients within one week in June 2013. Of these 940 patients, 869 (92.4%) met the inclusion criteria. In total, 291 (33.5%) eligible questionnaires (OLT group: 235, MELD <10: 25; MELD _10: 31) were suitable for analysis. General health (GH), vitality (VIT), and mental health (MH) were lower in both pretransplant groups compared to the OLT group (all p < 0.05). Anxiety and depression were higher in the MELD <10 group than in the OLT group (anxiety: p < 0.05; depression: p < 0.01). DISCUSSION: Patients with low MELD scores seem to benefit from OLT with regards to HRQoL and mental health.

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

BACKGROUND: The influence of immunosuppression on the recipients' quality of life (QoL) is of major importance after OLT and has not yet been evaluated. METHODS: The impact of different immunosuppression regimens after OLT was evaluated in 275 patients using the Short Form 36 (SF-36) survey. The following immunosuppressive strategies were compared: (a) CNI, (b) mTOR inhibitors, and (c) mTOR combined with CNI. All regimens were prescribed alone (mono) or in combination (+) with prednisolone and/or mycophenolate mofetil (MMF). RESULTS: Highest scores were evident in patients in the mTOR+ group. There were significantly higher values for general health perceptions (GH, p = 0.049), vitality (VIT, p = 0.020), and physical component summary (PCS, p = 0.041) when compared to CNImono and for GH (p = 0.042) and VIT (p = 0.043), when compared to mTORmono. Early conversion to mTOR inhibitors (two months after OLT), with a statistically significant improvement for the dimension role-emotional (RE, p = 0.027). DISCUSSION: mTOR inhibitor-based regimens appear to have beneficial effects on QoL after OLT, especially after an early conversion.

[Secondary defect coverage and functional reconstruction]. / Sekundäre Defektdeckung und funktionelle Rekonstruktion.

Secondary reconstruction in trauma surgery is crucial for restoring both functional and esthetic results in patients with complex defects. Established reconstructive techniques in plastic surgery offer a wide range of options for an effective treatment. This applies not only to covering large defects with free flaps but especially also for the functional reconstruction of bony, neural and musculotendinous impairments. Advances in the fields of microsurgery and 3D printing show innovative approaches to further improve the therapeutic options. A multidisciplinary approach, requiring close collaboration between trauma and plastic surgeons, is necessary to optimize treatment plans and outcomes. The effective management of complications and qualified postoperative care are essential for the success of reconstructive measures.
