Infection is a major limitation of implantable devices. Optimal antibiotic therapeutic regimes have not yet been defined. Implant-associated infections have a number of differentiating characteristics, which include the predominance of Staphylococcus epidermidis and other skin bacteria of normally low pathogenicity as the causative agents, together with a(More)
Renal artery stenosis may play a significant role in the pathogenesis of secondary hypertension, renal dysfunction, and flash pulmonary edema. Currently correction of renal arterial inflow stenosis is reserved for resistant hypertension patients who have failed maximal medical therapy, have worsening renal function and/or unexplained proximal congestive(More)
Implant-associated infections offer resistance to antibiotic treatment and possibly do so because the causative bacteria which reside on the artificial surface are enclosed in a protective matrix (biofilm) shielding the bacteria against the action of host defenses and antibiotic action. We have investigated in vitro the effect of various antimicrobial(More)
Routine laboratory testing of the susceptibility of infecting strains of S. epidermidis to antibiotics is based on the assumptions that the infection is in contact with the stable environment of blood or tissue fluid and that the bacteria are in a susceptible phase of growth. In infections of the continuous ambulatory peritoneal dialysis (CAPD)(More)
