BACKGROUND Procalcitonin (PCT) has been proposed as a diagnostic and prognostic sepsis marker, but has never been validated in febrile patients with prolonged ICU stay. METHODS Patients were included in the study provided they were hospitalised in the ICU for > 10 days, were free of infection and presented a new episode of SIRS, with fever >38 degrees C(More)
BACKGROUND Intensivists and nursing staff are often reluctant to admit patients with cancer to the intensive care unit even though these patients' survival rate has improved since the 1980s. OBJECTIVE To identify factors associated with mortality in cancer patients admitted to the intensive care unit and to assess and compare the effectiveness of 3(More)
The pathophysiology of pulmonary hypertension (PH) in parenchymal lung diseases is partially related to hypoxic pulmonary vasoconstriction. PH treatment is controversial for these patients. This article focuses on group III PH, namely PH attributable to lung diseases and/or hypoxia. Group III includes chronic obstructive pulmonary disease and interstitial(More)
INTRODUCTION Aspergillus spp. infections mainly affect patients who are immunocompromised, and are extremely rare in immunocompetent individuals. CASE PRESENTATION Aspergillus post-operative mediastinitis is considered to be a devastating infection, usually affecting patients undergoing cardiothoracic surgery with specific predisposing factors. We(More)
BACKGROUND The aim was to evaluate the clinical usefulness of a single plasma and bronchoalveolar lavage fluid (BALF) PCT and IL-6 measurement in discriminating septic from non-septic causes of acute respiratory distress syndrome (ARDS) and forecasting clinical outcomes. METHODS One hundred patients were enrolled within 48 h of ALI/ARDS recognition.(More)
INTRODUCTION Diabetic patients may develop acute lung injury less often than non-diabetics; a fact that could be partially ascribed to the usage of antidiabetic drugs, including metformin. Metformin exhibits pleiotropic properties which make it potentially beneficial against lung injury. We hypothesized that pretreatment with metformin preserves alveolar(More)
We report a case of severe ovarian hyperstimulation syndrome (OHSS) complicated by community-acquired methicillin-resistant Staphylococcus aureus-Panton-Valentine leukocidin positive (CAMRSA-PVL[+]) necrotizing pneumonia, sepsis and multiple organ failure (MOF) in a previously immunocompetent female. The patient required prolonged ventilatory support and(More)
Inflammatory mediators appear to be the most intriguing yet confusing subject, regarding the management of patients with acute coronary syndromes (ACS). The current inflammatory concept of atherosclerotic coronary artery disease (CAD) led many investigators to concentrate on systemic markers of inflammation, as well as imaging techniques, which may be(More)
BACKGROUND The role of the D allele of the angiotensin-converting enzyme (ACE) gene I/D polymorphism in the clinical outcomes of patients with acute lung injury and acute respiratory distress syndrome (ALI/ARDS) remains controversial. Our aim was to assess simultaneously the effect of the ACE I/D polymorphisms as well as the serum and BALF ACE levels on(More)
