Evidence is currently lacking regarding the outcomes of kidneys undergoing Hypothermic Machine Perfusion (HMP) in the UK. Using the National Health Service Blood and Transplant database, the authors compared outcomes for recipients of single organ Donation after Circulatory Death (DCD) kidneys preserved with HMP to those using only static cold storage (SCS). Between 2007 and 2015, HMP was used in 19.1% (864/4,529) of kidneys. Rates of delayed graft function (DGF) were significantly lower in organs preserved with HMP than for SCS (34...

BACKGROUND: Volumetric muscle loss (VML) following extremity orthopaedic trauma or surgery results in chronic functional deficits and disability. A current translational approach to address the devastating functional limitations due to VML injury is the use of an autologous minced muscle graft (~1 mm(3) pieces of muscle tissue) replacement into the injured defect area, although limitations related to donor site morbidity are still unaddressed. This study was designed to explore adjunct pharmacological immunomodulation to enhance graft efficacy and promote muscle function following VML injury, and thereby reduce the amount of donor tissue required...

REVIEW
Daniel Kwon, Alfred Iloreta, Brett Miles, Jared Inman
Skull base extirpative and reconstructive surgery has undergone significant changes due to technological and operative advances. While endoscopic resection and reconstruction will continue to advance skull base surgery for the foreseeable future, traditional open surgical approaches and reconstructive techniques are still contemporarily employed as best practices in certain tumors or patient-specific anatomical cases. Skull base surgeons should strive to maintain a working knowledge and technical skill set to manage these challenging cases where endoscopic techniques have previously failed, are insufficient from anatomical constraints, or tumor biology with margin control supersedes the more minimally invasive approach...

We describe a technique to reinforce a double-barreled aortic anastomosis in the repair of chronic aortic dissection. After distal aortic resection was carried out, an intimal flap was incised lineally 1 cm in width along with its margin. This intimal band was reapproximated to the adventitia which supported the false lumen. The wedge-shaped excision was made on the residual intimal flap to maintain blood flow to both the true and false lumens. Two felt strips were circumferentially placed inside and outside of the aortic edge, and the layers were sandwiched together with monofilament sutures...

Dermatofibrosarcoma protuberans with fibrosarcomatous differentiation (DFSP-FS) is a rare soft tissue tumor with more aggressive behavior and it is not clear what causes this type of skin cancer. We describe the case of a 48-year-old woman who was born with a vascular malformation in the sternal region and presented suddenly with a soft tissue sarcoma (DFSP-FS) in the same territory. She was initially treated by embolization as the sarcoma was misdiagnosed but the tumor within 6 months seemed to be growing rapidly and reached a giant dimension with ulceration and required surgical intervention...

BACKGROUND: Subcutaneous islet transplantation (SC Tx) is associated with minimal invasiveness, but poor vascularization. Thus, the optimization of the prevascularization procedures is crucial for improving the outcomes. Although the effectiveness of basic fibroblast growth factor (bFGF) was reported, the optimal procedures remain unclear. We sought to optimize the prevascularization procedures including the use of a novel scaffold, recombinant peptide (RCP). METHODS: Devices containing various amount of bFGF with/without heparin, or RCP were implanted into the subcutaneous space of diabetic C57BL/6 mice...
