We describe a patient with a 30-year history of mycosis fungoides (MF) and renal transplantation performed 3 years before he presented with an ulcerated tumour in the lumbosacral area. Biopsy revealed a lymphatic infiltrate of medium-sized, pleomorphic T cells expressing the gamma-delta T-cell receptor. Radiological staging and bone marrow biopsy revealed no extracutaneous involvement. Despite reduction in systemic immunosuppressants, total skin electron beam radiotherapy and systemic chemotherapy, the disease followed a highly aggressive course and the patient died 31 years after initial diagnosis of MF...

Organ transplantation is considered the therapy of choice for end-stage organ failure. However, the growing gap between the number of patients waiting for transplantation and available organs continue to be the number one issue facing the transplant community. As a consequence the major focus in liver transplantation has been developing strategies to increase available donors, including the use of live donor liver segments, splitting deceased donor grafts for two patients and the use of organs procured from donors after circulatory death (DCD)...

Follicular unit extraction (FUE) is one of the widely practiced minimally invasive follicular harvesting techniques employed during hair transplantation. FUE technique has an advantage of utilising lower occipital area and supra-auricular region as a safe donor area described by Unger, in addition to the standard occipital donor area used in strip method (follicular unit transplant). Despite its potential advantages such as rapid recovery, minimal scarring and reduced post-operative pain; its widespread acceptance is limited due to various factors in variable contribution like steeper learning curve and potentially higher follicular transection rates (FTRs)...

Regeneration in many organisms involves the formation of a blastema, which differentiates and organizes into the appropriate missing tissues. How blastema pattern is generated and integrated with pre-existing tissues is a central question in the field of regeneration. Planarians are free-living flatworms capable of rapidly regenerating from small body fragments [1]. A cell cluster at the anterior tip of planarian head blastemas (the anterior pole) is required for anterior-posterior (AP) and medial-lateral (ML) blastema patterning [2-4]...

BACKGROUND: We examined if African or Asian ethnicity was associated with lower access to kidney transplantation (KT) in a Canadian setting. METHODS: Patients referred for KT to the Toronto General Hospital from January 1, 2003 to December 31, 2012, who completed social work assessment, were included (n=1769). The association between ethnicity and the time from referral to completion of KT evaluation or receipt of a KT were examined using Cox proportional hazards models...

Knee osteoarthritis (OA) after partial or total meniscectomy is a prevalent issue that patients must face. Various methods of replacing meniscal tissue have been studied to avoid this progression, including meniscal allograft transplantation, meniscal scaffolds, and synthetic meniscus replacement. Studies have shown that meniscal scaffolds may improve symptoms but have not been shown to prevent progression of OA. Recently, mesenchymal stem cells (MSCs) have been proposed as a possible biological therapy for meniscal regeneration...

BACKGROUND: Alcohol dependent liver transplantation (LT) patients who resume alcohol are at risk for a number of alcohol related problems including liver injury and liver failure. Post LT patients are strongly advised to remain abstinent. However, we don't know how well this population complies due to a lack of valid methods (self-report and/or biomarkers) to identify alcohol use. Studies suggest as many as 50% resume alcohol use within 5 years. Phosphatidylethanol (PEth) is a new cell-membrane phospholipid biomarker to identify alcohol use in the past 28 days...

An 11-year-old girl presented to our tertiary eye care centre with a 9-month-old history of lime injury in the left eye in 1999 with vision of counting fingers close to the face. She initially underwent superficial keratectomy with amniotic membrane graft in 1999. Subsequently, cultivated limbal epithelial transplantation was performed in 2001 which improved her vision to 20/400. Following development of pannus and symblepharon in the left eye, she underwent pannus resection and conjunctival limbal autograft in 2002 and, a month later, optical penetrating keratoplasty (PK) following which her vision improved to 20/125...

Fertility preservation in prepubertal boys facing gonadotoxic treatment is still at the experimental stage. Nevertheless cryopreservation of immature testicular tissue (ITT) obtained by small testicular biopsy is being increasingly proposed in reproductive care clinics for this purpose. Different approaches to in vivo or in vitro mature spermatogonial stem cells (SSCs) contained in ITT have been studied: autografting of testicular tissue pieces, transplantation of one's own purified germ cell suspensions, and in vitro maturation (IVM) for subsequent use of sperm for intra cytoplasmic sperm injection (ICSI)...

Adult mesenchymal stromal cell-based interventions have shown promising results in a broad range of diseases. However, their use has faced limited effectiveness owing to the low survival rates and susceptibility to environmental stress on transplantation. We describe the cellular and molecular characteristics of multilineage-differentiating stress-enduring (Muse) cells derived from adipose tissue (AT), a subpopulation of pluripotent stem cells isolated from human lipoaspirates. Muse-AT cells were efficiently obtained using a simple, fast, and affordable procedure, avoiding cell sorting and genetic manipulation methods...

The current strategies for healing bone defects are numerous and varied. At the core of each bone healing therapy is a biomimetic mechanism, which works to enhance bone growth. These range from porous scaffolds, bone mineral usage, collagen, and glycosaminoglycan substitutes to transplanted cell populations. Bone defects face a range of difficulty in their healing, given the composite of dense outer compact bone and blood-rich inner trabecular bone. As such, the tissue possesses a number of inherent characteristics, which may be clinically harnessed as promoters of bone healing...

Preterm birth is the leading cause of death in newborns and children. Despite advances in perinatology, immature infants continue to face serious risks such chronic respiratory impairment from bronchopulmonary dysplasia (BPD). Current treatment options are insufficient and novel approaches are desperately needed. In recent years stem cells have emerged as potential candidates to treat BPD with mesenchymal stem/stromal cells (MSCs) being particularly promising. MSCs originate from several stem cell niches including bone marrow, skin, or adipose, umbilical cord, and placental tissues...

The evolution of managing short gut syndrome optimizes management and decision making of intestinal failure by way of a multidisciplinary team utilizing the latest advances in therapeutic options. Only the minority of patients referred for small bowel transplantation will actually need a transplant. Many of these patients can be rehabilitated without the need for transplant, by way of early referral, and thus the likelihood of medical therapy increases. On the other hand, in those patients with little likelihood of success with medical therapy, early referral decreases the morbidity and mortality associated with long-term total parenteral nutrition and associated complications and will improve their overall survival outcomes...

BACKGROUND AND OBJECTIVES: Bowel cancer is a leading cause of cancer-related death in people with CKD. Shared decision making regarding cancer screening is particularly complex in CKD and requires an understanding of patients' values and priorities, which remain largely unknown. Our study aimed to describe the beliefs and attitudes to bowel cancer screening in patients with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Face to face, semistructured interviews were conducted from April of 2014 to December of 2015 with 38 participants ages 39-78 years old with CKD stages 3-5, on dialysis, or transplant recipients from four renal units in Australia and New Zealand...

Burn scars remain a serious physical and psychological problem for the affected. Clinical studies as well as basic scientific research have shown that Medical Needling can significantly increase the quality of burn scars with comparatively low risk and stress for the patient with regards to skin elasticity, moisture, erythema and transepidermal water loss. However, Medical Needling has no influence on repigmentation of large hypopigmented scars. The goal is to evaluate whether both established methods - Needling (improvement of scar quality) and ReNovaCell (repigmentation) - can be combined...

Allogeneic hematopoietic cell transplant (allo-HCT) represents the earliest form of immunotherapy used to treat multiple myeloma (MM). Since the first successful myeloablative allografts were performed in the early 1980s, highly effective new agents to treat this disease have been identified at an unprecedented pace. Currently, sixteen FDA-approved therapies are available to treat MM. As a consequence of these advances, the median overall survival for standard risk MM patients has extended to over 7 years...

Ten years after the first face transplantation we report the partial loss of this graft. After two episodes of acute rejection (AR) occurred and completely reversed in the first post-transplantation year, ninety months post-transplantation the patient developed de novo class II-donor specific antibodies, without clinical signs of AR. Some months later she developed several skin rejection episodes treated with steroid pulses. Despite rapid clinical improvement, some months later the sentinel skin graft underwent necrosis...

BACKGROUND The human face is a one-of-a-kind structure with unique morphology, complexity, and function, in which different subunits are not even similar to other parts of the body. Therefore, extended complex deficits of the face are usually difficult to reconstruct, and autologous tissue restoration is generally not able to give a satisfactory aesthetic and functional outcome. The main goal of face allotransplantation is to restore symmetry, contour, and appearance as well as function of the face, especially control of orbicularis oculi and oris muscle physiology...

In small children with end-stage renal disease, an adult-size kidney transplant is the best option. However, in the face of a completely thrombosed inferior vena cava (IVC), such transplants can be challenging, given the difficulty of achieving adequate renal venous outflow and the risk of graft thrombosis. Using a new technique to anastomose the renal vein to the right hepatic vein/IVC junction, we successfully implanted an adult-size graft in 2 small children (9.8 kg and 14 kg) who had end-stage renal disease and a completely thrombosed IVC...
