For treatments requiring split-thickness skin grafts, it is preferable to mesh the grafts. This reduces the amount of excised skin and covers more wound area. The mesh technique, however, destroys surface continuity, which results in scarring. Strain-based bioreactors, on the other hand, have successfully expanded split-thickness skin grafts in vitro within a 7-day period, increasing graft coverage. After in vitro expansion, the expanded skin grafts were tested in a porcine full-thickness excisional wound model...

The PI3K/mTOR signaling cascade is fundamental in T-cell activation and fate decisions. We showed the distinct regulation of PI3K/mTOR in regulatory and effector T-cells and proposed the potential therapeutic benefit of targeting this pathway to control the balance between effector and regulatory T-cell activities. Substantial adverse effects in long-term clinical usage of Rapamycin suggest the use of alternative treatments in restraining effector T-cell function in transplant patients. We hypothesize that dual PI3K/mTOR inhibitors may represent an immunosuppressant alternative...

The repair of lower leg defects, not amenable to primary closure, may be challenging, since the skin at this level is scarcely elastic and difficult to mobilize. Local skin flaps are generally utilized only to restore moderately sized losses, whereas grafting becomes a realistic choice in presence of larger wounds. We present the case of a 70-year-old man with a wide defect on his right leg following the surgical excision of a squamous cell carcinoma. The wound was successfully closed with a combination of three hatchet flaps...

Necrotizing fasciitis is a serious infection of the skin and soft tissues. Pasteurella multocida is rarely reported to cause necrotizing fasciitis and is associated with high mortality. We describe a female patient with a past medical history of diabetes mellitus and myeloproliferative disorder presenting with bullae and erythema of the right forearm secondary to P. multocida infection after possible cat bite. Despite adequate antibiotic coverage she developed necrotizing fasciitis diagnosed clinically and on diagnostic imaging...

The newer and potent immunosuppressive agents have successfully reduced the risk of rejection after kidney transplantation, but the development of cardiovascular diseases, infections, and malignancy is major factors limiting their success. Posttransplantation malignancy is the second most common cause of death in renal transplant recipients after cardiovascular disease; it is expected that mortality due to malignancy may become the most common cause of death within the next two decades. This study is designed to evaluate the incidence, risk factors, and types of malignancies occurring after renal transplantation and their impact on patient and graft survival...

Graft infection following aortic aneurysms repair is an uncommon but devastating complication; its incidence ranges from <1% to 6% (mean 4%), with an associated perioperative and overall mortality of 12% and 17.5-20%, respectively. The most common causative organisms are Staphylococcus aureus and Escherichia coli; causative bacteria typically arise from the skin or gastrointestinal tract. The pathogenetic mechanisms of aortic graft infections are mainly breaks in sterile technique during its implantation, superinfection during bacteremia from a variety of sources, severe intraperitoneal or retroperitoneal inflammation, inoculation of bacteria during postoperative percutaneous interventions to manage various types of endoleaks, and external injury of the vascular graft...

Reconstructive surgery to the lips requires the replacement of defective tissues with similarly functioning tissues. While non-dynamic free tissue transfers provide adequate lower lip reconstruction, improved benefits may be obtained with innervated free muscle flaps. This study reports the use of innervated serratus anterior muscle free flaps for lip reconstruction in five patients. All patients had squamous cell carcinoma of either the upper or lower lip. After resection of the tumours, the resultant defects comprised two-thirds of the lips...
