Filter by:Previous report showed that 37% of patients with moderate to severe carbon monoxide (CO) poisoning experienced a myocardial injury, defined as elevated cardiac enzyme [creatine kinase, CK-MB, and cardiac troponin I (TnI)] or ischemic electrocardiogram (ECG) change. In other study, 24% of the patients with the myocardial injury after CO poisoning died during a median follow-up of 7.6 years. The myocardial injury was the major predictor of mortality. In addition, in the Taiwanese nationwide population-based cohort study, CO poisoning itself reported as a higher risk of a major adverse cardiovascular event. According to the previous study of investigators, among CO poisoned patients with myocardial injury, 74.4% of patients experienced CO-induced cardiomyopathy. All CO-induced cardiomyopathy recovered to normal status. In this situation, there is no definite approved reason why more cardiovascular events are occurred in CO poisoned patients with myocardial injury during long term follow-up period despite normalization of CO-induced elevated TnI and cardiac dysfunction. Two image cases related to cardiac magnetic resonance imaging (CMR) in acute CO poisoning previously reported. One image case reported that patient had mildly depressed left ventricular (LV) systolic function with hypokinesis of the anterior wall and regional akinesis of the inferior wall on the transthoracic echocardiography performed during hospitalization and late gadolinium-enhancement (LGE) images of CMR demonstrated multiple focal areas of high signal consistent with myocardial necrosis or fibrosis. Another image case reported an image case that in CMR, inferolateral mid-wall myocardial fibrosis, which was defined as LGE, was present despite the setting of a completely normal echocardiogram at 4-month follow-up in CO poisoned patients. Therefore, the investigators evaluate prevalence (frequency of LGE positive) and patterns (involved LV wall and range of LGE positive) of myocardial fibrosis (LGE positive) in acute CO-poisoned patients during acute (within seven days after CO exposure) and chronic phase (at 4-5 months after CO exposure) and whether LGE positive developed in acute phase have been changed through cardiac MRI performed at chronic phase. The investigators also evaluate LV ejection fraction and global longitudinal strain in transthoracic echocardiography performed at the ED (baseline) and within seven days (follow-up). The investigators also assessed the association between neurocognitive outcomes using the global deterioration scale (at 1, 6, and 12 months after CO exposure) and the presence of LGE positive.
Aim of the study: To assess the role of intralipid emulsion in the acute man-agement of organophosphorus toxicity and its benefits in de-creasing mortality rates among victims.
Poisoning is the deterioration of the body's functions by the ingestion of any substance being toxic to the body or by overdosing a nontoxic substance. Poisoning cases may vary according to the geographical and seasonal characteristics of the region, sociocultural structure of the population, life index and the age groups. Worldwide, intentional self-poisoning (ISP) is the most common form of suicide attempt and the most common method that results in medical hospitalization.
Metal phosphides are widely used as a rodenticide and insecticide and poisoning with these substances has a very high mortality. The aim of this study was to evaluate the butyrylcholinesterase (BuCh) level in poisoning with metal phosphides.
Aluminum phosphide (AlP) or rice tablet is a cheap pesticide. When it comes in contact with acid (gastric acid) or moisture, it releases phosphine (PH3) gas. The heart,lungs, liver are the main targets in acute Aluminum phosphide (AlP) poisoning. Most deaths occur due to cardiovascular toxicity.
NBMI (N1, N3-Bis-(2-Mercaptoethyl) Isophthalamide) is a new metal chelator drug proposed as an alternative to the current chelators, and it is widely different; compared to the current chelators, consisting of two cysteamine molecules coupled to a single molecule of dicarboxybenzoate. It is used as a chelating agent and has the designation of an orphan drug, in the EU and USA; in the EU it is used for the treatment of mercury toxicity. It is freely soluble in solutions of dimethylformamide (DMF), dimethyl sulfoxide (DMSO) and sodium hydroxide diluted NaOH, slightly soluble in methanol and acetone, and insoluble in water. Pre-clinical data indicates low to no toxicity, and that it reduces the toxicity associated with acute exposure to Hg2+. No other chelator has been reported to prevent acute mercury toxicity with only one exposure to the chelator. It has the ability to penetrate cell membranes and cross the blood-brain barrier and chelate Hg2+ in a complex that eliminates the availability of Hg2+ and essentially eliminates toxic effects. The antioxidant properties of NBMI could also reduce the toxicity levels of hydroxyl free radicals immediately, upon entering cells suffering from oxidative stress. It is possible that the combined chelation of Hg2+ and the elimination of hydroxyl free radicals contribute significantly to the protective effects observed with the NBMI. Previous clinical studies conducted in subjects of the Phase I and Phase II a studies conducted, did not show significant adverse events in patients intoxicated with mercury, all patients who received the study medication have tolerated it well, with only mild or moderate adverse events reported; None of these were considered related to the pharmacological treatment of the study. In addition, there is no potential identified with safety problems in laboratory tests, or vital signs evaluations. The purpose of this Controlled Single-Center Double-Blind Crossover Clinical Trial Phase II b is to determine the efficacy, safety and tolerability of a 14 day 600mg / day of NBMI (N1, N2-bis-2-mercaptoethyl isophthalamide) Treatment, in the reduction of urinary mercury levels versus placebo, in accidentally exposed subjects to mercury in Colombia.
Paraquat is a common human toxicant and accounts for 20 deaths per million persons in the world. Paraquat usually cause multiple organ dysfunction syndrome, including liver, kidney, lung and heart dysfunction. Besides, pituitary insufficiency also occurs on those patients with paraquat poisoning, which leads to multiple endocrine gland dysfunction, involving adrenal gland, thyroid and sex gland. As a result, the investigators decide to initiate the clinical trial to find whether thyroid replacement therapy can furtherly reduce the mortality, and improve patients long-term prognosis.
In some patients, a few days or weeks after recovery from carbon monoxide poisoning, new symptoms develop. These can affect mood, ability to think or remember clearly, and movements. Some people develop movement problems that are similar to Parkinson's disease. This damage to brain tissue is called "encephalopathy," and this study will look at the effect of pressurized oxygen therapy on long term, or chronic, encephalopathy.
The study aimed to investigate the association between RDW and in-hospital mortality in methanol poisoning.
The investigators designed a monitoring and control table of a citrate treatment on a specific monitor. This is the Baxter "Prismaflex" monitor, with 8.2 software version. Dialysis bath liquids marketed by Baxter: Biphozyl are used. Citrate liquid (1:18) Regiocit is used. The dialysis treatment monitor (CVVHD) is programmed, with a blood / citrate pumps at a rate of 1:10 (1 ml / min of blood: 10 ml / h of dialysis fluid) The starting dose of citrate will be 3.5 mmol / l and the calcium compensation will be 100% Working hypothesis: The patient undergoing citrate anticoagulation according to the designed algorithm will respond with ion stability and pH during the treatment, in addition to achieving an effective cleaning process.
