BACKGROUND Three anatomical sites are commonly used to insert central venous catheters, but insertion at each site has the potential for major complications. METHODS In this multicenter trial, we randomly assigned nontunneled central venous catheterization in patients in the adult intensive care unit (ICU) to the subclavian, jugular, or femoral vein (in a(More)
INTRODUCTION Prognostic factors in intentional insulin self-poisoning and the significance of plasma insulin levels are unclear. We therefore conducted this study to investigate prognostic factors in insulin poisoning, in relation to the value of plasma insulin concentration. METHODS We conducted a prospective study, and used logistic regression to(More)
Morphine is responsible for severe poisonings in chronically treated patients. We hypothesize that toxicity could be related to the development of weaker tolerance for morphine-induced deleterious respiratory effects in comparison to analgesic effects. Our objectives were to compare tolerance to both effects in mice and investigate possible mechanisms for(More)
INTRODUCTION The prognostic value of cardiac troponin I (cTnI) in patients having a heat-related illness during a heat wave has been poorly documented. METHODS In a post hoc analysis, we evaluated 514 patients admitted to emergency departments during the August 2003 heat wave in Paris, having a core temperature >38.5 degrees C and who had analysis of cTnI(More)
Approximately 20-30 declared snakebite cases occurin Martinique each year. Bothrops lanceolatus, a member of the Crotalidae family, is considered to be the only involved snake. B. lanceolatus, commonly named "Fer-de-Lance", is endemic and only found on this Caribbean island. Envenomation local features include the presence of fang marks, swelling, pain,(More)
BACKGROUND Psychosis can be associated with acute recreational drug and novel psychoactive substance (NPS) toxicity. However, there is limited data available on how common this is and which drugs are most frequently implicated. We describe a European case series of psychosis associated with acute recreational drug toxicity, and estimate the frequency of(More)
INTRODUCTION Methadone, the most widely delivered maintenance therapy for heroin addicts, may be responsible for life-threatening poisonings with respiratory depression. The toxicokinetics and the toxicokinetic/toxicodynamic (TK/TD) relationships of methadone enantiomers have been poorly investigated in acute poisonings. The aim of this study was to(More)
Regardless of stringent safety regulations and increased compound selectivity by pharmaceutical companies, prediction of toxicity in humans is still far from perfect and adverse drug reactions are still detected after drug marketing. High costs of failures due to toxicity has led pharmaceutical companies to search for screening methods that would allow(More)
A 42-year-old man from Bhutan was admitted to the emergency department with a 5-day history of abdominal pain, nausea and vomiting. Enhanced abdominal CT scan was found negative, however laboratory tests showed hemolytic anemia and basophilic stippling which are often seen in lead and heavy metal poisoning. Additional tests revealed a high level of lead in(More)
Gastrointestinal (GI) diseases affect a large number of people all over the world. Uncontrolled acid secretion and occurrence of gastric ulcers are common disorders of GI tract which pose serious problems to human health. Many synthetic drugs have been used to treat GI disorders but a definite cure has not been discovered so far and the available(More)
