Fifty-four cases of Achromobacter xylosoxidans bacteremia diagnosed over a 10-year period in patients from 2 months to 87 years of age were reviewed. Fifty-two episodes were nosocomial. The most frequent underlying condition was neoplasm (solid or hematological). The source of infection was a contaminated intravenous catheter in 35 patients (60%) and(More)
Abdominal pain associated with nausea and vomiting in a young patient led to a diagnosis of median arcuate ligament syndrome. The presence of mild haematuria was associated with a concomitant Nutcracker syndrome. Diagnosis was achieved by a computed tomography scan, which showed compression of the vessels of the coeliac axis and left renal vein. These(More)
Most pairwise comparison (PC) methods typically require the explicit elicitation of only half of the comparisons, and infer the rest by assuming reciprocity in the decision maker’s comparisons. However, this may imply losing useful information contained in the additional comparisons that could be made, and which might be different from the first ones. This(More)
We report immunological studies performed in 19 sera from 4 children with idiopathic pulmonary hemosiderosis (IPH). Circulating C1q binding immune complexes (IC) were found in 3/4 of the patients during the acute phase. One child showed IC in 4 consecutive crises but they disappeared very rapidly (within 36 hours). Only one serum was positive after acute(More)
OBJECTIVE To prospectively analyze the results obtained with papillary balloon dilatation (PBD) in the treatment of common bile duct stones in patients at risk of complications if endoscopic sphincterotomy (ES) were performed. PATIENTS AND METHOD Thirty-three patients were included between January 2001 and June 2003 (mean age 76.2 years). The criteria for(More)
Tumor necrosis factor (TNF) is a potent proinflammatory cytokine involved in asthma and atopy. Increased TNF-alpha levels have been found in airway biopsies and bronchoalveolar lavage fluids from asthmatic patients. Constitutional variations in the TNF-alpha secretion levels in vitro are associated with molecular polymorphisms located within and around the(More)
Energy efficiency and conservation are major factors in the reduction of environmental impact of the energy sector, particularly with regard to climate change. Energy efficiency also contributes to reducing external dependence and vulnerabilities in the energy domain. In this paper we discuss the factors that influence energy efficiency and conservation(More)
The objective of this study is to determine if treatment with the angiogenesis inhibitor TNP-470 results in impairment of oxidative stress, inhibition of nuclear factor kappa B (NF-kappaB) activation and decrease of nitric oxide production in an experimental model of rat hepatocarcinogenesis. Tumour was induced by diethylnitrosamine and promoted by(More)
This paper tries to contribute to the well-known and lengthy discussion on whether we should allow decision makers to be inconsistent, or, to put it in another way, if intransitive decisions better represent their preferences. We will focus specifically on the multiple-criteria decision making problem, since it is one of the most usual stances where this(More)
