BACKGROUND The emergence of multidrug-resistant nosocomial pathogens, such as Pseudomonas aeruginosa and Acinetobacter baumannii, has led to the revival of the systemic use of antimicrobial agent colistin in critically ill patients, but only limited data are available to define its pharmacokinetic profile in these patients. OBJECTIVE The aim of this study(More)
Colistin pharmacokinetics were prospectively studied after intravenous administration of colistin methanesulphonate in critically ill patients without central nervous system infection (controls, n = 5) and in patients with external ventricular drain-associated ventriculitis after intravenous administration (EVDViv, n = 3) or combined(More)
Linezolid is a new antimicrobial agent effective against drug-resistant gram-positive pathogens commonly responsible for central nervous system (CNS) infections in neurosurgical patients hospitalized in intensive care units. In order to study the penetration of this antimicrobial into the cerebrospinal fluid (CSF) of such patients, the disposition of(More)
STUDY OBJECTIVES To estimate the penetration of gentamicin into lung tissue by measuring its concentrations in alveolar lining fluid (ALF) and blood in critically ill patients with ventilator-associated pneumonia (VAP). PATIENTS AND INTERVENTIONS The study population consisted of 24 patients who were admitted to an ICU for respiratory failure and(More)
Nitric oxide (NO), produced by endothelial nitric oxide synthase (eNOS), plays a key role in the regulation of vascular tone. Endothelium-derived NO exerts vasoprotective effects by suppressing platelet aggregation, leukocyte adhesion and smooth muscle cell proliferation. The E298D polymorphic variant of eNOS has been associated with myocardial infarction(More)
Data relating to the pharmacokinetics of voriconazole in critically ill patients are lacking. A prospective observational study was conducted on 18 non-consecutive critically ill patients aged 24-97 years, comprising 12 patients with normal renal function (NRF) [creatinine clearance (CL(Cr)) > or = 60 mL/min] and 6 patients with moderate renal impairment(More)
BACKGROUND The prophylactic administration of antimicrobial agents to surgical patients has become standard practice to minimize the risk for postsurgical infection. During surgery, factors such as renal clearance, fluid administration, and blood loss contribute to drug concentrations achieved in the blood and tissues. The aminoglycoside gentamicin was(More)
OBJECTIVE To estimate the effectiveness of a short-term educational-counseling worksite program focused on lipid intake, by monitoring the possible change on nutrition knowledge and eating habits. METHODS an 8-week educational program based on the Health Belief Model was implemented in a honey packaging and sales company in Greece. 20 out of the 29(More)
18590 Background: Combinations of β-lactam antibiotics and aminoglycosides are considered standard therapy for febrile neutropenia. Monotherapies have been proposed as standard treatments, demonstrating equal efficacy and better safety. METHODS This is a prospective, multi-centre, randomized clinical trial. Cancer patients with absolute neutrophil count(More)
