BACKGROUND A method of diagnosing catheter-related infection (CRI) without removing the catheter would be useful. An earlier positivity of central compared with peripheral venous-blood cultures may be associated with catheter-related bacteraemia. We evaluated prospectively the differential time to positivity (DTP) of paired blood cultures drawn(More)
BACKGROUND Peritoneal carcinomatosis (PC) is fatal, despite standard systemic chemotherapy. A new approach that combines maximal surgery with maximal regional chemotherapy has potential to cure selected patients who have colorectal PC. The authors have reported the oncologic results of this combined treatment. METHODS The authors performed a retrospective(More)
Although several advantages are attributed to tracheotomy in ICU patients requiring mechanical ventilation (MV), true benefits and the optimal timing of tracheotomy remain controversial. In this study, we compared early tracheotomy (ET) with prolonged intubation (PI) in severely ill patients requiring prolonged MV. Prospective, randomized study. Twenty-five(More)
CONTEXT Invasive life-support techniques are a major risk factor for nosocomial infection. Noninvasive ventilation (NIV) can be used to avoid endotracheal intubation and may reduce morbidity among patients in intensive care units (ICUs). OBJECTIVE To determine whether the use of NIV is associated with decreased risk of nosocomial infections and improved(More)
To diagnose catheter-related sepsis without removing the catheter, we evaluated the differential positivity times of cultures of blood drawn simultaneously from central venous catheter and peripheral sites. In a 450-bed cancer reference center, simultaneous central- and peripheral-blood cultures were prospectively performed for patients with suspicion of(More)
The admission of neutropenic patients to an intensive care unit (ICU) is still controversial, especially if mechanical ventilation is required. To avoid useless stays in ICU, the evaluation of the respective role of the underlying malignancy and acute organ failures might be useful for better definition of the categories of patients who could benefit from(More)
Ventilator-associated pneumonia (VAP) is difficult to detect and is often unsuspected during adult respiratory distress syndrome (ARDS). We prospectively evaluated lower respiratory tract (LRT) colonization and infection in 30 patients with severe ARDS (PaO2/FIO2 ratio < 150 mm Hg), using repeated quantitative cultures of plugged telescopic catheter (PTC)(More)
OBJECTIVES To use three severity of illness scores to estimate the probability of hospital mortality among patients with cancer and neutropenia; to compare the performance of these scores, calculated at admission to an intensive care unit (ICU); and to test the improvement in estimation obtained by taking into account the first 72-hr period. DESIGN(More)
PURPOSE Because the overall outcome of critically ill hematologic patients has improved, we evaluated the short-term and long-term outcomes of the poor risk subgroup of allogeneic hematopoietic stem-cell transplantation (HSCT) recipients requiring admission to the intensive care unit (ICU). PATIENTS AND METHODS This was a retrospective multicenter study(More)
