Acute Poisoning (acute + poisoning)
Selected AbstractsDepleted uranium,the growing concernJOURNAL OF APPLIED TOXICOLOGY, Issue 3 2002Aqel W. Abu-Qare Abstract Recently, several studies have reported on the health and environmental consequences of the use of depleted uranium. Depleted uranium is a heavy metal that is also radioactive. It is commonly used in missiles as a counterweight because of its very high density (1.6 times more than lead). Immediate health risks associated with exposure to depleted uranium include kidney and respiratory problems, with conditions such as kidney stones, chronic cough and severe dermatitis. Long-term risks include lung and bone cancer. Several published reports implicated exposure to depleted uranium in kidney damage, mutagenicity, cancer, inhibition of bone, neurological deficits, significant decrease in the pregnancy rate in mice and adverse effects on the reproductive and central nervous systems. Acute poisoning with depleted uranium elicited renal failure that could lead to death. The environmental consequences of its residue will be felt for thousands of years. It is inhaled and passed through the skin and eyes, transferred through the placenta into the fetus, distributed into tissues and eliminated in urine. The use of depleted uranium during the Gulf and Kosovo Wars and the crash of a Boeing airplane carrying depleted uranium in Amsterdam in 1992 were implicated in a health concern related to exposure to depleted uranium.

[source] Paediatric poisonings treated in one Finnish main university hospital between 2002 and 2006ACTA PAEDIATRICA, Issue 6 2008Juho E Kivistö Abstract Aim: Acute poisonings are a major cause of morbidity among children. This study aims to describe the incidence and nature of emergency visits for acute paediatric poisoning among Finnish children. Methods: All patients younger than 16 years admitted to the Tampere University Hospital's emergency department with a diagnosis of poisoning during 2002,2006 were identified from the Hospital Information System using the International Classification of Diseases (ICD-10). Results: Altogether 369 emergency visits were diagnosed with poisoning, the overall incidence being 8.1 per 10 000 person,years (95% CI 7.3,9.0). A majority of patients were adolescents aged 10,15 years (48%) and children under 5 years (45%). Boys represented 55% of the cases. Nonpharmaceutical agents were suspected to be the cause in 60.4% and pharmaceuticals in 30.6% of the intoxications. Multiple agents were involved in 8.4% of the cases. Ethanol was the agent in 30.9% of the poisonings. Most patients (78.9%) were hospitalized (median length of stay 1 day). Overall mortality was 0.3%. Conclusion: Acute paediatric poisonings represent a relatively frequent problem in Finland, and remain a life-threatening problem. The high proportion of alcohol poisonings highlights the necessity to develop more effective primary prevention programs. [source] Cardiopulmonary effects of HI-6 treatment in soman intoxicationJOURNAL OF APPLIED TOXICOLOGY, Issue S1 2001A. Göransson-Nyberg Abstract The cardiopulmonary effects of HI-6, together with atropine and soman, were studied in the rat. HI-6 is an effective antidote in acute poisoning with the nerve agent soman. The therapeutic efficiency of HI-6 is still unclear and cannot be explained entirely by the HI-6 reactivating ability of acetylcholinesterase (AChE). Other non-cholinergic factors must be involved. One possible detoxifying process might be an effect of HI-6 on the blood flow to sensitive organs. The purpose of the present study was to investigate 1) whether soman per se induces changes in regional blood flow and 2) whether the blood flow to different organs is affected when HI-6 (50 mg kg,1 i.m.) and atropine (10 mg kg,1 i.m.) are given either before or immediately after soman intoxication (90 µg kg,1 s.c.). For regional blood flow determinations the microsphere method was used with male Wistar rats weighing 300,400 g. The rats were anaesthetised and breathed spontaneously during the experiment. Three different blood flow measurements were made in the same animal and concomitant physiological parameters such as mean arterial blood pressure and respiratory rate were recorded. The blood AChE activity was followed throughout the experiment. Our results show that when HI-6 is given after intoxication with soman, dramatic changes in blood flow occur with a significant decrease in both respiratory rate and blood AChE activity. If HI-6 is given prior to the intoxication, however, all rats are unaffected and none of the parameters measured are changed. Copyright © 2001 John Wiley & Sons, Ltd. [source] Surrogate Alcohol: What Do We Know and Where Do We Go?ALCOHOLISM, Issue 10 2007Dirk W. Lachenmeier Background:, Consumption of surrogate alcohols (i.e., nonbeverage alcohols and illegally produced alcohols) was shown to impact on different causes of death, not only poisoning or liver disease, and appears to be a major public health problem in Russia and elsewhere. Methods:, A computer-assisted literature review on chemical composition and health consequences of "surrogate alcohol" was conducted and more than 70 references were identified. A wider definition of the term "surrogate alcohol" was derived, including both nonbeverage alcohols and illegally produced alcohols that contain nonbeverage alcohols. Results:, Surrogate alcohol may contain substances that cause severe health consequences including death. Known toxic constituents include lead, which may lead to chronic toxicity, and methanol, which leads to acute poisoning. On the other hand, the role of higher alcohols (e.g., propanol, isobutanol, and isoamyl alcohol) in the etiology of surrogate-associated diseases is currently unclear. Whether other constituents of surrogates have contributed to the high all-cause mortality over and above the effect of ethanol in recent studies also remains unclear. Conclusions:, Given the high public health importance associated with the consumption of surrogate alcohols, further knowledge on its chemical composition is required as well as research on its links to various disease endpoints should be undertaken with priority. Some interventions to reduce the harm resulting from surrogate alcohol could be undertaken already at this point. For example, the use of methanol or methanol-containing wood alcohol should be abolished in denatured alcohol. Other possible surrogates (e.g., automobile products) should be treated with bittering agents to avoid consumption. [source] Availability of antidotes for the treatment of acute poisoning in Queensland public hospitalsAUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 2 2010Lisa M. Nissen Abstract Objective:,To determine the sufficiency of stock levels of 13 antidotes in Queensland hospitals. Design:,A self-report survey was sent to 128 Queensland hospitals with acute care facilities. The stock level of the following antidotes was determined: acetylcysteine, anti-digoxin Fab antibodies (digibind), atropine, calcium gluconate, cyanokit, desferrioxamine, flumazenil, glucagon, intravenous ethanol, methylene blue, naloxone, pralidoxime and pyridoxine. Other factors sampled were bed capacity, rural, remote and metropolitan areas classification, use of formal stock reviews by pharmacists or nurses, existence of formal borrowing agreements with other facilities for non-stocked antidotes, distance to the nearest referral hospital and time taken to transfer antidotes from another hospital. Participants:,Pharmacists or nurses responsible for maintaining antidote stocks in Queensland hospitals. Main outcome measures:,Proportions of hospitals with sufficient antidote stock to treat a 70-kg adult for four or more hours using previously published guidelines. Results:,Survey response rate was 73.4%. No hospital had sufficient stock of all 13 antidotes. The proportion of hospitals with sufficient stocks varied from 0% (pyridoxine) to 68.1% (acetylcysteine). Larger hospitals had a higher frequency of sufficient antidote stocks. Only 16% of hospitals claimed to be able to acquire an antidote from another facility within 30 min. Conclusions:,Most Queensland hospitals stocked some important antidotes, but few had sufficient stock to treat a 70-kg patient or acquire an antidote within the recommended time frame of 30 min. Specific antidote stocking guidelines might be required for Queensland hospitals. A formalised program for stock rotation with rural facilities should be explored. [source] Reduced risk of acute poisoning in Australian cattle from used motor oils after introduction of lead-free petrolAUSTRALIAN VETERINARY JOURNAL, Issue 6 2010BG Burren Lead (Pb) poisoning of cattle has been relatively common in Australia and sump oil has been identified as an important cause of Pb toxicity for cattle because they seem to have a tendency to drink it. Lead-free petrol has been available in Australia since 1975, so the aim of this study was to assess the current risk to cattle from drinking used automotive oils. Sump or gear box oil was collected from 56 vehicles being serviced. The low levels of Pb found suggest that the removal of leaded petrol from the Australian market as a public health measure has benefited cattle by eliminating the risk of acute poisoning from used engine oil. [source] Ethylene glycol intoxication misdiagnosed as eclampsiaACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 3 2006I. Kralova Ethylene glycol intoxication is one of the most serious acute poisonings with very uncertain prognosis with regard to both recovery and survival. A case report is presented in which a woman who was admitted for the termination of pregnancy by Caesarean section with a diagnosis of eclampsia turned out to be severely intoxicated by ethylene glycol.
