Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma affecting children and is often diagnosed with concurrent metastases. Unfortunately, few effective therapies have been discovered that improve the long-term survival rate for children with metastatic disease. Here we determined effectiveness of targeting the receptor tyrosine kinase, EphB4, in both alveolar and embryonal RMS either directly through the inhibitory antibody, VasG3, or indirectly by blocking both forward and reverse signaling of EphB4 binding to EphrinB2, cognate ligand of EphB4...

Patients with displaced patellar fractures typically present with disruption to the extensor mechanism requiring acute surgical intervention. Chronic patellar fractures with disruption of the extensor mechanism are uncommon, and few surgical options are available. The authors present a patient who sustained a fracture to the inferior pole of the patella in Africa 5 years prior that was managed conservatively with bands and a brace. He decided to pursue surgical intervention because of difficulties with leg extension, weakness, and ambulation...

The objective of this network meta-analysis was to identify and rank different ridge preservation procedures using allograft, xenograft, or extraction only by dimensional changes in ridge width and height after tooth extraction. Electronic and hand searches of several databases were performed in September 2016 to identify randomized controlled trials on extraction and ridge preservation with 3 to 7 months of follow-up. Eight studies were included in the network meta-analysis. The total number of teeth included in these trials was 466, which were randomly assigned to treatment groups...

STUDY DESIGN: Cross-sectional survey study. OBJECTIVE: To determine what are the most commonly used graft materials in anterior cervical discectomy and fusion and whether the choice of graft is affected by surgeon's training, years in practice, geographic location, practice setting, or surgeon's perceived difficulty in achieving fusion. METHODS: A 23-question survey was sent out to 5334 surgeons using the Global AO Spine database. Response data was then stratified into surgeon training, years of practice, practice type, and global region...

BACKGROUND: Infected non-unions of the supracondylar region of the femur are uncommon. Even though hardware removal is a common procedure, it may lead to complications, including neurovascular injury, refracture, worsening pain or recurrence of deformity. CASE PRESENTATION: We report on a male who developed subcutaneous emphysema of the leg after hardware removal and bone allografting for an infected non-union of the distal femur. He was managed by debridement of the surgical wound, antibiotic therapy, multiple fasciotomies, and application of a VAC (vacuum-assisted closure) system...

Heart-lung transplant is the most effective therapy for patients with end-stage cardiopulmonary disease. Here, we report an initial assessment of a 31-year-old man who had survived more than 11 years after heart-lung transplant, which represents the longest survival time in this procedure in Asian studies. At his 11th anniversary after transplant, extensive tests were carried out, especially to detect regulatory T-cell levels for the first time in a surviving heart-lung transplant recipient. Preliminarily data revealed the status of his immunologic function in relation to chronic allograft rejection...

Background: Steroid-avoidance protocols have gained popularity in pediatric kidney transplant recipients at low immunologic risk. The long-term safety of steroid avoidance in children with immunologic risk factors remains unknown. Methods: Pediatric kidney transplant recipients from 2004 to 2014 in the Organ Procurement and Transplantation Network database who received tacrolimus and mycophenolate immunosuppression were investigated. Propensity score matching was used to compare graft survival in 1624 children who received steroid avoidance with 1624 children who received steroid-based immunosuppression...

In the not so distant past, organs from hepatitis C infected donors were either discarded or rarely transplanted into HCV viremic recipients - but never allocated to non-infected patients. However, the simplicity, ease and unprecedented success rates of HCV direct acting antiviral regimens has raised the possibility of utilizing such organs in an attempt to expand the donor pool. The thinker trial reports the first of such attempts. However, caution must be exercised prior to the widespread adoption of such strategy...

M J Kraus, A M Nowakowski
We report a 72-year-old man who underwent fixation with a multifilament cerclage system after a peri-prosthetic trochanteric fracture (Vancouver A1). Failure of cerclage occurred after 23 month and revision of trochanteric attachment was performed due to non-union. Intraoperatively fragments of the cable were found between prosthesis head and liner. Cup and head were changed and the greater trochanter was re-attached after allograft-impaction. Based on the present case report multifilament cerclage cables should be used with precaution and might require a close and frequent follow-up given the possibility of cerclage breakage and consecutive catastrophic wear by migration of cerclage particles...

Renal allograft rupture (RAR) is a rare but lethal complication of renal transplantation. It potentially threatens graft and patient survival. RAR is frequently associated with acute rejection, but other causes like renal vein thrombosis and acute tubular necrosis have also been observed. Most commonly a graft nephrectomy is required, but graft repair can also be attempted in selected cases to salvage the graft. Herein, we describe a rare case of spontaneous renal allograft rupture in the early posttransplant period due to acute tubular necrosis...

INTRODUCTION: Suboptimal healing of the tendon bone interface (TBI) remains an unsolved problem. One solution is a biocompatible tissue engineered construct that promotes augmented healing. We hypothesisze that 1.) the presence of Platelet Rich Plasma (PRP) and prolonged in vitro incubation produces tissue engineered tendon bone interface scaffolds with greater reseeding of viable Adipo-derived Stem Cells (ADSC) and 2.) when implanted with extracellular matrix hydrogel, constructs will display superior in vivo strength repair and biocompatibility...

JC polyomavirus (JCPyV)-associated nephropathy (JCPyVAN) occurs in < 3% of PVAN cases after renal transplantation. We report the first confirmed case to our knowledge of JCPyVAN diagnosed by kidney biopsy in the early 6 months post transplant in Thailand. In this case report, recovery of renal allograft function was not observed after reduction of immunosuppressive agents and administration of intravenous immunoglobulin and cidofovir. Despite persistent JCPyV viruria, no significant further decline in allograft function was documented at 15 months post transplant...

Hematopoietic cell transplant is a potentially curative procedure for many benign and malignant conditions. The efficacy of allogeneic transplant relies in part on the cytotoxicity of the conditioning regimen and the graft versus tumor effect mediated by alloreactive donor T cells; the same cells are also implicated in the development of graft versus host disease (GVHD). Selective identification and depletion of the T cells implicated in GVHD, while preserving the T cells responsible for graft versus tumor effect has been the focus of many research groups in the recent years...

Post-transplant diabetes mellitus (PTDM) is a metabolic disorder occurring after solid organ transplantation during the therapy with calcineurin inhibitors. ATP-sensitive potassium channels KCNJ11 and KCNQ1 play an important role in the regulation of insulin secretion by β cells and development of diabetes mellitus. Numerous studies have confirmed the association between KCNJ11 and KCNQ1 gene polymorphisms and type 2 diabetes. The aim of this study was to examine the association between KCNJ11 and KCNQ1 gene polymorphisms and posttransplant diabetes mellitus in kidney allograft recipients treated with tacrolimus...
