OBJECTIVES The incidence of ventilator-associated pneumonia (VAP) due to multidrug-resistant (MDR) organisms is increasing. Intravenous (IV) colistin or aerosolized (AS) plus IV colistin have been recently used to treat these life-threatening infections. The purpose of this study was to compare the efficacy and safety of AS plus IV colistin versus IV(More)
To compare the diagnostic performance of lung ultrasound and bedside chest radiography (CXR) for the detection of various pathologic abnormalities in unselected critically ill patients, using thoracic computed tomography (CT) as a gold standard. Forty-two mechanically ventilated patients scheduled for CT were prospectively studied with a modified lung(More)
To assess the impact of lung ultrasound (LU) on clinical decision making in mechanically ventilated critically ill patients. One hundred and eighty-nine patients took part in this prospective study. The patients were enrolled in the study when LU was requested by the primary physician for (1) unexplained deterioration of arterial blood gases and (2) a(More)
The POEM group, 1992 General circulation of the Eastern Mediterranean Sea Earth-Sct Ret', 32 285 308 A novel description of the phenomenology of the Eastern Me&terranean is presented based upon a comprehensive pooled hydrographic data base collected during 1985-1987 and analyzed by cooperating scientists from several restitutions and nations (the POEM(More)
Patient-ventilator asynchrony refers to the uncoupling between the mechanically delivered breath and the patient's respiratory effort. It is common during assisted mechanical ventilation and may affect the morbidity of critically ill patients. Close inspection of pressure, volume and flow waveforms - displayed by modern ventilators - may help the physician(More)
OBJECTIVE To summarize current knowledge regarding the diagnosis and management of gastrointestinal vasculitis. METHODS Three cases of gastrointestinal vasculitis with acute abdominal ischemia as their first manifestation are presented. Underlying diseases were microscopic polyangiitis, systemic lupus erythematosus (SLE), and polyarteritis nodosa (PAN).(More)
The aim of this study was to investigate the changes induced by high tidal volume ventilation (HVTV) in pulmonary expression of micro-RNAs (miRNAs) and identify potential target genes and corresponding miRNA-gene networks. Using a real-time RT-PCR-based array in RNA samples from lungs of mice subjected to HVTV for 1 or 4 h and control mice, we identified 65(More)
Although liver metastases are commonly found in cancer patients, fulminant hepatic failure (FHF) secondary to diffuse liver infiltration is rare. Furthermore, clinical presentation and laboratory findings are obscure and far from being pathognomonic for the disease. We report a case of a patient who died in the intensive care unit of our hospital from(More)
In the context of assisted ventilation in ICU, it is of vital importance to keep a high synchronization between the patient’s attempt to breath and the assisted ventilation event, so that the patient receives the ventilation support requested. In this work, experimental equipment is employed, which allows for unobtrusive and continuous monitoring of a(More)
OBJECTIVE To evaluate silver-impregnated (Oligon) central venous catheters and chlorhexidine-gluconate-impregnated sponges for reducing catheter-related colonization and infection, nonbacteremic or bacteremic. DESIGN Multicenter, prospective, randomized, controlled study. SETTING Five general intensive care units in Greece. PATIENTS Intensive care(More)
