BACKGROUND: Ankle fractures account for 9% of all fractures seen in the United Kingdom. 15,000 of these fractures undergo operative fixation each year. Soft tissue swelling impacts on timing of fixation due to fears of infection and wound dehiscence. The use of arterio-venous foot pumps (AVFP) is increasing in this population although the evidence for their efficacy is unclear. In order to address this, we present an overview of the evidence for AVFP device use following ankle fracture...

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by production of inflammatory cytokines and autoreactive antibodies due to the loss of immune tolerance. Recognition of self-nucleic acids by intracellular Toll-like receptors (TLRs) can overactivate immune responses and this abnormal activation of TLRs contributes to the pathogenesis of the disease. In recent years, anti-inflammatory and immunomodulatory effects of 1, 25-dihydroxyvitamin D3 (VitD3) on the immune system has received particular attention...

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...
