Is two-stage revision surgery for infected hip arthroplasty worth the suffering, resources and results compared to one-stage?

Purpose: Periprosthetic joint infection (PJI) is the most serious complication of total hip arthroplasty. The treatment is usually revision in either 1 or 2 stages. This study analyses revision with impaction bone grafting for periprosthetic joint infection of the hip and compares 1- and 2-stage strategies.

Protection Against Lipopolysaccharide-Induced Immunosuppression by IgG and IgM.

Lipopolysaccharide (LPS) is commonly used in murine sepsis models, which are largely associated with immunosuppression and collapse of the immune system. After adapting the LPS treatment to the needs of locally bred BALB/c mice, the present study explored the potential role of IgG and IgM in reversing LPS endotoxemia. The established protocol consisted of five daily intraperitoneal injections of 0.

l-Carnitine affects preimplantation embryo development toward infertility in mice.

l-Carnitine (l-Cn), despite the beneficial role as energy-generating substance delivering long-chain fatty acids to the β-oxidation pathway in mitochondria, has been accused to cause an endometriosis-like state to BALB/c mice manifested by increased inflammatory cytokines in serum and peritoneal fluid, accumulation of immune cells in the peritoneal cavity and uterine walls and most importantly, correlating to infertility. Exploring this type of infertility, the effect of l-Cn on preimplantation embryo development, ovarian integrity and systemic maternal immunity was studied. Using nonlinear microscopy analysis, which was shown to be a powerful tool for determining embryo quality by quantitatively estimating the lipid body (LB) content of the cells, it was shown that in vitro and in vivo administration of l-Cn significantly decreased LB mean area in zygotes.

Supervision of thrombolysis of acute myocardial infarction using telemedicine.

The treatment of acute myocardial infarction (MI) constitutes a significant problem in remote geographical areas of Greece. Furthermore, thrombolysis, the treatment of choice in the early phase of acute MI, requires the supervision of an expert. We have used thrombolytic treatment, using telemedicine, in remote medical centres.
