Abstract

The prevalence of Stapylococcus bacteriaemia is increasing worldwide, because of the increasing use of invasive procedures leading to nosocomial infections, but also of a changing way of life (increasing fashion for tattoos or piercing, use of intravenous drugs). Infective endocarditis develops in 10-30% of the cases of staphylococcus bacteriaemia. Staphylococcus aureus endocarditis must be suspected when it develops in the year following heart surgery or implantation of permanent devices. In drug users, it usually involves the tricuspid valve. According to the resistance of the germ to meticillin, antibiotic therapy uses a combination of intravenous penicillin or glycopeptide and an aminoside. Other antibiotics such as fosfomycin, rifampicin, fusidic acid, or clindamycin can be used when aminosides are contra-indicated. The role of newer antibiotic agents, such as daptomycin or linezolide, remains to be established.

Abstract

Cidofovir (CDF) or Vistid is a monophosphate nucleoside analogue that inhibits the DNA polymerase of herpes viruses including the cytomegalovirus (CMV). CDF is active on GCV-resistant strains with a mutation on the phosphotransferase gene (UL97). However, DNA polymerase gene mutations that induce resistance to GCV are responsible for cross-resistance to CDF. Resistance phenotypes to GCV and CDF were determined for 57 CMV strains isolated from blood and urine samples. Sixteen strains were recovered after CDF therapy. Of the remaining 41 CDF-naive strains, 34 were susceptible and seven resistant to GCV. Fifty percent inhibitory concentrations (IC50) for CDF were in the 0.2-2.6 microM range for CDF-naive strains susceptible to GCV. For GCV-resistant strains, IC50 values for CDF were < or = 3 microM for strains with a low level of resistance to GCV (GCV IC50 < 30 microM) and > or = 6 microM for three of the five strains with a high level of resistance to GCV (GCV IC50 > or = 30 microM).

16. [Renal artery stenosis and aorto-iliac restoration: is it necessary to do extensive evaluation?].

Abstract

In patients with aortoiliac disease and a stenosis of one or two renal artery, renal hypertension is rarely the sole mechanism of the elevated blood pressure. The preservation of nephron mass being the aim of the renal revascularization, we firmly believe that only three tests are required for the operative decision: renal ultrasonography, nephroscintigraphy and global and selective aortography.
