    Cases of acute pesticide poisoning (APP) account for significant morbidity and mortality worldwide. Developing countries are particularly susceptible due to poorer regulation, lack of surveillance systems, less enforcement, lack of training and inadequate access to information systems. Previous research has demonstrated wide variability in incidence rates for APP. This is possibly due to inconsistent reporting methodology and exclusion of occupational and non-intentional poisonings. The purpo...

    Cases of acute pesticide poisoning (APP) account for significant morbidity and mortality worldwide. Developing countries are particularly susceptible due to poorer regulation, lack of surveillance systems, less enforcement, lack of training and inadequate access to information systems. Previous research has demonstrated wide variability in incidence rates for APP. This is possibly due to inconsistent reporting methodology and exclusion of occupational and non-intentional poisonings. The purpose of this document is to create a standard case definition to facilitate the identification and diagnosis of all causes of APP, especially at the field level, rural clinics and primary health-care systems. This document is a synthesis of existing literature and case definitions that have been previously proposed by other authors around the world. It provides a standardized case definition and classification scheme for APP into categories of probable, possible and unlikely/unknown cases. Its use is intended to be applicable worldwide to contribute to identification of the scope of existing problems and thus promote action for improved management and prevention. By enabling a field diagnosis for APP, this standardized case definition may facilitate immediate medical management of pesticide poisoning and aid in estimating its incidence.

    Organophosphorus pesticide self-poisoning is an important clinical problem in rural regions of the developing world, and kills an estimated 200,000 people every year. Unintentional poisoning kills far fewer people but is a problem in places where highly toxic organophosphorus pesticides are available. Medical management is difficult, with case fatality generally more than 15%. We describe the limited evidence that can guide therapy and the factors that should be considered when designing further clinical studies. 50 years after first use, we still do not know how the core treatments--atropine, oximes, and diazepam--should best be given. Important constraints in the collection of useful data have included the late recognition of great variability in activity and action of the individual pesticides, and the care needed cholinesterase assays for results to be comparable between studies. However, consensus suggests that early resuscitation with atropine, oxygen, respiratory support, and fluids is needed to improve oxygen delivery to tissues. The role of oximes is not completely clear; they might benefit only patients poisoned by specific pesticides or patients with moderate poisoning. Small studies suggest benefit from new treatments such as magnesium sulphate, but much larger trials are needed. Gastric lavage could have a role but should only be undertaken once the patient is stable. Randomised controlled trials are underway in rural Asia to assess the effectiveness of these therapies. However, some organophosphorus pesticides might prove very difficult to treat with current therapies, such that bans on particular pesticides could be the only method to substantially reduce the case fatality after poisoning. Improved medical management of organophosphorus poisoning should result in a reduction in worldwide deaths from suicide.

    2005-01-01

    The International Code of Conduct on the Distribution and Use of Pesticides of the Food and Agriculture Organization (FAO) of the United Nations has been for 20 years the most acknowledged international initiative for reducing negative impact from pesticide use in developing countries. We analyzed pesticide use and poisoning in Central America, particularly in Costa Rica and Nicaragua, and evaluated whether registration decisions are based on such data, in accordance with the FAO Code. Extensive use of very hazardous pesticides continues in Central America and so do poisonings with organophosphates, carbamates, endosulfan and paraquat as the main causative agents. Central American governments do not carry out or commission scientific risk assessments. Instead, guidelines from international agencies are followed for risk management through the registration process. Documentation of pesticide poisonings during several decades never induced any decision to ban or restrict a pesticide. However, based on the official surveillance systems, in 2000, the ministers of health of the seven Central American countries agreed to ban or restrict twelve of these pesticides. Now, almost 4 years later, restrictions have been implemented in El Salvador and in Nicaragua public debate is ongoing. Chemical and agricultural industries do not withdraw problematic pesticides voluntarily. In conclusion, the registration processes in Central America do not comply satisfactorily with the FAO Code. However, international regulatory guidelines are important in developing countries, and international agencies should strongly extend its scope and influence, limiting industry involvement. Profound changes in international and national agricultural policies, steering towards sustainable agriculture based on non-chemical pest management, are the only way to reduce poisonings

    Objective: To analyze the characteristics of acute pesticide poisoning in Ningbo, and to provide scientific basis for the prevention and control strategy. Methods: In February 2017, the pesticide poisoning report card of Ningbo from 2011 to 2016 was drawn from the China Disease Control and prevention information system. The data of the report card was organized by Excel and analyzed by SPSS19.0 software. Results: 2593 cases of acute pesticide poisoning were reported in Ningbo from 2011 to 2016, 125 deaths, and the case fatality rate was 4.82%. The productive pesticide poisoning and unproductive pesticide poisoning were 299 and 2294, respectively, the ratio was 1: 7.67. The case fatality rate were 0.33% and 5.41%, respectively. The difference was statistically significant (χ(2)=14.83, PPesticide poisoning mainly occurred from July to September (55.85%) , the unproductive pesticides mainly occurred from April to June (30.64%) and July to September (30.34%). The seasonal distribution of the pesticide poisoning in the two groups was statistically significant (χ2=82.21, Ppesticide poisoning in male (80.27%) was significantly higher than the proportion of unproductive pesticide poisoning (52.09%) , the differences in gender composition between the two types of pesticide poisoning was significant (χ2=84.97, Ppesticide poisoning from 55 to 65 years old group was in the largest number (35.45%) , and the distribution of unproductive pesticide poisoning was uniform in each age group including 25 years old and above, the difference in age composition between two types of pesticide poisoning was statistically significant (χ2=177.84, Ppesticide poisoning. The counties with more reports were Ninghai county (18.28%) , Fenghua district (14.69%) and Yuyao (12.42%). The acute pesticide poisoning was mainly caused by pesticides and herbicides, mainly in organophosphorus (45.74%) and paraquat (16.81%) .

    Pesticides are chemical toxicants which are used to kill by their toxic actions, the pest organisms, known to incur significant economic losses or threaten human life, his health and that of his domesticated animals. These toxicants are seldom species-specific. The presence of these or their metabolites may scientific be vouched not only in the environment they are used, but in the entire ecosystem, in the subsoil, in the underwater reservoirs and in the food chain of all non-target species including man, his friends i.e. predator and parasite organisms which be uses against the pests, and in his cherished domesticated animals. In the present paper a survey is made of different groups of toxic chemicals generally used to manage pests, in the ecosystem, food chain and tissues and body parts of non-target species including man and the ones dear to him. Toxicology and biochemistry of these toxic materials and their important metabolites are also briefly discussed with special reference to ways and means through which these poison the above non-target species.

    Full Text Available Background. Acute pesticide poisoning (APP is a serious problem worldwide. Because the burden of childhood APP is unknown in Tanzania, this study describes the distribution, circumstances, and patterns of APP involving children under 18 years in Tanzania. Methodology. A 12-month prospective study was conducted in 10 Tanzanian healthcare facilities in 2006 using a data collection tool for surveillance. Results. Of 53 childhood poisoning cases identified, 56.6% were female. The most common poisoning circumstances were accidents (49.1% and suicide (30.2%. The most vulnerable children were 16-17 years old (30.2%. Suicide was significantly more common in females (PRR females/males = 1.66; 95% CI = 1.03–2.68 and accidental cases were more common in children aged 10 years or younger. Suicide was concentrated in children over 10 years, comprising 53% of cases in this age group. Organophosphates (OPs, zinc phosphide, and endosulfan were common amongst reported poisoning agents. The annual APP incidence rate was 1.61/100,000. Conclusion. APP is common among children in this region of Tanzania. Prevention of suicide in older children should address mental health issues and control access to toxic pesticides. Prevention of accidents in younger children requires safer storage and hygiene measures. Diverse interventions are needed to reduce pesticide poisoning among children in Tanzania.

    2008-01-04

    Pyraclostrobin is an agricultural pesticide product used to kill fungi (e.g., blights, mildews, molds, and rusts). Hazards to humans from pyraclostrobin exposure include eye injury and skin irritation. In July 2007, the Iowa Department of Public Health (IDPH) received reports of five events involving pyraclostrobin that sickened 33 persons, including 27 migrant workers who were exposed in a single incident during aerial application (i.e., crop dusting). This report describes those five events and provides recommendations for preventing additional illnesses associated with exposure to pyraclostrobin.

MATERIAL Y MÉTODOS: Se revisaron los expedientes de 33 pacientes ³ 13 años, tratados en una unidad de cuidados intensivos (UCI, entre 1994 y 1998. Se recopilaron variables demográficas y clínicas relevantes, y se aplicó estadística descriptiva. RESULTADOS: En la población estudiada predominó el sexo masculino (82% del medio rural (70%, y la edad media fue de 34 ± 15.8 años. El intento de suicidio fue causa frecuente de IAP (79%, y en 33% de los casos la intoxicación se produjo por la utilización de organofosforados. La mortalidad fue de 12%. CONCLUSIONES: La IAP fue baja entre los sujetos del medio rural, por lo que los resultados de este estudio parecen no reflejar la realidad del problema. Es importante añadir que los plaguicidas son utilizados con relativa frecuencia para el intento de suicidio.OBJECTIVE: To describe the epidemiologic pattern of acute pesticide poisoning (APP in a general hospital in Merida, Yucatan, Mexico. MATERIAL AND METHODS: From 1994 to 1998, 33 patients 13 years of age or older with diagnosis of APP were studied. Descriptive statistics were used to analyze information. RESULTS: Males were frequently affected (82%, specially those coming from rural areas (60%. The mean age of the group was 34 ± 15.8 years. In 79% of the cases, pesticides were used to commit suicide and 33% of poisoning cases were due to organophospate pesticides. The mortality rate was 12%. CONCLUSIONS: In this small sample, acute poisoning from pesticides in the agricultural setting may be underestimated, since it was less frequent than in the general population. APP was more commonly used by indigent people to commit suicide.

    In Paraguay, pesticides are the causative agent in 13.7% of poisonings, especially organophosphorus compounds. Such poisoning produces the inhibition of acetylcholinesterase generating three possible clinical conditions: acute poisoning, intermediate syndrome or late neurotoxicity. We present 15 cases of acute poisoning, ten women and five men from a rural community between 5 and 67 years of age, whose symptoms began after using water contaminated by pesticides from the community network. The most common symptoms were nausea and vomiting, followed by abdominal pain, headache, fever, itching, red eyes and sweating. Five patients underwent blood tests for blood count, renal and liver function and serum cholinesterase, with results within the reference values; just one patient had high liver enzymes.In two samples from the community water supply network the active compound detected was profenophos. It is essential to train primary health care personnel to identify cases of acute pesticide poisoning in a timely manner to provide appropriate treatment, especially in rural areas.

    2006-10-01

    Full Text Available Abstract Background Organophosphorus (OP pesticide poisoning is the most common form of pesticide poisoning in many Asian countries. Guidelines in western countries for management of poisoning indicate that gastric lavage should be performed only if two criteria are met: within one hour of poison ingestion and substantial ingested amount. But the evidence on which these guidelines are based is from medicine overdoses in developed countries and may be irrelevant to OP poisoning in Asia. Chinese clinical experience suggests that OP remains in the stomach for several hours or even days after ingestion. Thus, there may be reasons for doing single or multiple gastric lavages for OP poisoning. There have been no randomised controlled trials (RCTs to assess this practice of multiple lavages. Since it is currently standard therapy in China, we cannot perform a RCT of no lavage vs. a single lavage vs. multiple lavages. We will compare a single gastric lavage with three gastric lavages as the first stage to assess the role of gastric lavage in OP poisoning. Methods/Design We have designed an RCT assessing the effectiveness of multiple gastric lavages in adult OP self-poisoning patients admitted to three Chinese hospitals within 12 hrs of ingestion. Patients will be randomised to standard treatment plus either a single gastric lavage on admission or three gastric lavages at four hour intervals. The primary outcome is in-hospital mortality. Analysis will be on an intention-to-treat basis. On the basis of the historical incidence of OP at the study sites, we expect to enroll 908 patients over three years. This projected sample size provides sufficient power to evaluate the death rate; and a variety of other exposure and outcome variables, including particular OPs and ingestion time. Changes of OP level will be analyzed in order to provide some toxic kinetic data. Discussion the GLAOP study is a novel, prospective cohort study that will explore to the toxic

    Full Text Available Background: Acute pesticide poisoning (APP is commonly underdiagnosed in Tanzania. Studies in developing countries suggest that a lack of diagnostic skills among health care providers (HCPs undermines surveillance for APP. This study aimed at characterizing experience and skills of Tanzanian HCPs regarding APP diagnosis and management. Methodology: The population included HCPs responsible for managing APP in Kilimanjaro and Arusha regions (n = 91. The resulting sample included 66 respondents (response rate: 73%. The data were collected in 2005 using a standardized questionnaire. Results: Half of all respondents (50% reported handling at least 1 APP case with 15% reporting handling more than 5 cases in the past. Reported experience of handling an APP case was marginally higher in respondents who reported ⩾4 years of work experience in the health sector compared with those with <4 years of work experience (odds ratio = 1.32; 95% confidence interval = 0.9-1.5. Most of the respondents had high knowledge of exposure routes, reporting awareness of oral (98.5%, inhalational (93.9%, and dermal (77% routes. The study revealed low awareness of pesticide classification by chemical groups (29% or World Health Organization hazard (0% and weak knowledge on pesticide label instructions (55%. Organophosphates accounted for 35% of the pesticide products reported by respondents as being responsible for poisoning. Some treatment options were incorrectly reported as first aid options, and some reported first aid options were wrong or inappropriate. Conclusions: The study revealed that HCPs in northern Tanzania lack adequate skills to diagnose and manage APP. For effective surveillance of APP, there is a need to include training on hazards, classification, diagnosis, and health effects in the training programmes for all HCPs in Tanzania.

    Acetylcholinesterase inhibition by organophosphorus pesticides or organophosphate nerve agents can cause acute parasympathetic system dysfunction, muscle weakness, seizures, coma, and respiratory failure. Prognosis depends on the dose and relative toxicity of the specific compound, as well as pharmacokinetic factors. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute organophosphorus poisoning? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 62 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: activated charcoal (single or multiple doses), alpha(2) adrenergic receptor agonists, atropine, benzodiazepines, butyrylcholinesterase replacement therapy, cathartics, extracorporeal clearance, gastric lavage, glycopyrronium bromide (glycopyrrolate), ipecacuanha (ipecac), magnesium sulphate, milk or other home remedy immediately after ingestion, N-methyl-D-aspartate receptor antagonists, organophosphorus hydrolases, oximes, removing contaminated clothes and washing the poisoned person, and sodium bicarbonate.

    The high incidence of pesticide ingestion as a means to commit suicide is a critical public health problem. An important predictor of suicidal behavior is suicide ideation, which is related to stress. However, studies on how to defend against stress-induced suicidal thoughts are limited. This study explores the impact of stress on suicidal ideation by investigating the mediating effect of self-efficacy and dispositional optimism. Direct and indirect (via self-efficacy and dispositional optimism) effects of stress on suicidal ideation were investigated among 296 patients with acute pesticide poisoning from four general hospitals. For this purpose, structural equation modeling (SEM) and bootstrap method were used. Results obtained using SEM and bootstrap method show that stress has a direct effect on suicide ideation. Furthermore, self-efficacy and dispositional optimism partially weakened the relationship between stress and suicidal ideation. The final model shows a significant relationship between stress and suicidal ideation through self-efficacy or dispositional optimism. The findings extended prior studies and provide enlightenment on how self-efficacy and optimism prevents stress-induced suicidal thoughts.

  7. The power of poison: pesticide poisoning of Africa's wildlife.

    2014-08-01

    Poisons have long been used to kill wildlife throughout the world. An evolution has occurred from the use of plant- and animal-based toxins to synthetic pesticides to kill wildlife, a method that is silent, cheap, easy, and effective. The use of pesticides to poison wildlife began in southern Africa, and predator populations were widely targeted and eliminated. A steep increase has recently been observed in the intensity of wildlife poisonings, with corresponding population declines. However, the majority of poisonings go unreported. Under national laws, it is illegal to hunt wildlife using poisons in 83% of African countries. Pesticide regulations are inadequate, and enforcement of existing legislation is poor. Few countries have forensic field protocols, and most lack storage and testing facilities. Methods used to poison wildlife include baiting carcasses, soaking grains in pesticide solution, mixing pesticides to form salt licks, and tainting waterholes. Carbofuran is the most widely abused pesticide in Africa. Common reasons for poisoning are control of damage-causing animals, harvesting fish and bushmeat, harvesting animals for traditional medicine, poaching for wildlife products, and killing wildlife sentinels (e.g., vultures because their aerial circling alerts authorities to poachers' activities). Populations of scavengers, particularly vultures, have been decimated by poisoning. Recommendations include banning pesticides, improving pesticide regulations and controlling distribution, better enforcement and stiffer penalties for offenders, increasing international support and awareness, and developing regional pesticide centers. © 2014 New York Academy of Sciences.

    Full Text Available Abstract Background Globally, there is a growing concern over pesticides use, which has been linked to self-harm and suicide. However, there is paucity of research on the epidemiology of pesticides poisoning in Nepal. This study is aimed at assessing epidemiological features of pesticides poisoning among hospital-admitted cases in selected hospitals of Chitwan District of Nepal. Methods A hospital-based quantitative study was carried out in four major hospitals of Chitwan District. Information on all pesticides poisoning cases between April 1 and December 31, 2015, was recorded by using a Pesticides Exposure Record (PER form. Results A total of 439 acute pesticides poisoning cases from 12 districts including Chitwan and adjoining districts attended the hospitals during the 9-month-long study period. A majority of the poisoned subjects deliberately used pesticides (89.5% for attempted suicide. The total incidence rate was 62.67/100000 population per year. Higher annual incidence rates were found among young adults (111.66/100000 population, women (77.53/100000 population and individuals from Dalit ethnic groups (98.22/100000 population. Pesticides responsible for poisoning were mostly insecticides (58.0% and rodenticides (20.8%. The most used chemicals were organophosphates (37.3% and pyrethroids (36.7%. Of the total cases, 98.6% were hospitalized, with intensive care required for 41.3%. The case fatality rate among admitted cases was 3.8%. Conclusions This study has indicated that young adults, females and socially disadvantaged ethnic groups are at a higher risk of pesticides poisoning. Pesticides are mostly misused intentionally as an easy means for committing suicide. It is recommended that the supply of pesticides be properly regulated to prevent easy accessibility and misuse. A population-based study is warranted to reveal the actual problem of pesticides exposure and intoxication in the community.

    Full Text Available Abstract Background Pesticide poisoning is an important health problem among Chinese farm workers, but there is a paucity of pesticide poisoning data from China. Using the WHO standard case definition of a possible acute pesticide poisoning, we investigated the prevalence and risk factors of acute work-related pesticide poisoning among farmers in Southern China. Methods A stratified sample of 910 pesticide applicators from two villages in southern China participated in face-to-face interviews. Respondents who self-reported having two or more of a list of sixty-six symptoms within 24 hours after pesticide application were categorized as having suffered acute pesticide poisoning. The association between the composite behavioral risk score and pesticide poisoning were assessed in a multivariate logistic model. Results A total of 80 (8.8% pesticide applicators reported an acute work-related pesticide poisoning. The most frequent symptoms among applicators were dermal (11.6% and nervous system (10.7% symptoms. Poisoning was more common among women, farmers in poor areas, and applicators without safety training (all p 2 = 0.9246. Conclusions This study found that 8.8% of Chinese pesticide applicators suffered acute pesticide poisoning and suggests that pesticide safety training, safe application methods, and precautionary behavioral measures could be effective in reducing the risk of pesticide poisoning.

    Acute pesticide poisoning in developing countries is a considerable problem, requiring diagnosis and treatment. This study describes how training of health care workers in Uganda affects their ability to diagnose and manage acute pesticide poisoning. A postintervention cross-sectional study was conducted using a standardized questionnaire. A total of 326 health care workers in Uganda were interviewed on knowledge and handling of acute pesticide poisoning. Of those, 173 health care workers had received training, whereas 153 untrained health care workers from neighboring regions served as controls. Trained health care workers scored higher on knowledge of pesticide toxicity and handling of acute pesticide poisoning. Stratification by sex, profession, experience, and health center level did not have any influence on the outcome. Training health care workers can improve their knowledge and treatment of pesticide poisonings. Knowledge of the subject is still insufficient among health care workers and further training is needed.

    According to the present knowledge, none of the currently available oximes (pralidoxime, obidoxime, trimedoxime, MMB-4 or HI-6) originally developed for the treatment of the nerve agent poisonings is able to treat organophosphorus pesticide poisoning. Among them, obidoxime seems to be the best candidate, however, its high toxicity disfavors its application in the high quantities. As byproduct of our searching for the new nerve agent reactivators, we found that oxime K027 seems to be very promising in the case of the treatment of organophosphorus pesticide poisonings. Its reactivation potency is similar or better than that of obidoxime, and moreover, its acute toxicity is lower. Thanks to these results, this oxime seems to be the best candidate for future use as universal reactivator for the treatment of poisonings caused by organophosphorus pesticides.

    Pesticide poisoning in children has been a serious public health issue around the world, especially in the developing countries where agriculture is still one of the largest economic sectors. The purpose of this study was to analyze epidemiological characteristics of acute pesticide poisoning in children from Zhejiang province, China. The pesticide poisoning cases for children were retrieved from Occupational Disease Surveillance and Reporting System, Zhejiang Provincial Center for Disease Control and Prevention, China. The incident cases, deaths, and fatality rate of child pesticide poisoning from 2006 through 2015 were calculated. During the study period, totally 2952 children were poisoned by pesticides, with 66 deaths, resulting in a fatality rate of 2.24%. Among them, there were 1607 male cases with 28 deaths, and 1345 female cases with 38 deaths. Most of the cases occurred in preschool children (1349) and adolescent age group (1269). Organophosphate and carbamate insecticides were the cause of most poisonings (1130), leading to 34 deaths. The highest fatality rate (3.13%) was due to poisoning by herbicides and fungicides, causing 14 deaths out of 448 cases. Poisoning occurred mostly in rural areas (78%). And most pesticide poisoning occurred in the summer (896) and fall (811), while fewest poisoning cases in the winter (483) but with the highest fatality rate (3.52%). This study shows that pesticide poisoning of children is a major health problem in Zhejiang, suggesting preventive strategies should be conducted to control childhood pesticide poisoning.

    Objective: To summarize the CT and MR imaging findings in acute organophosphorus pesticides poisoning patients, and to improve the early diagnostic ability. Methods: The imaging of 34 patients of organophosphorus pesticides poisoning was analyzed, the poisons were all taken orally. The pesticides included methamidophos (12 cases), omethoate (15 cases), DDV (3 cases), and methylparathion (4 cases). According to the diagnosis and classification diagnosis criterion of acute organophosphorus pesticides poisoning, the patients were divided into two groups: mild or moderate grade group (24 cases) and severe grade group (10 cases). The relationship between the clinic grade and CT and MRI findings was studied. Results: in the severe grade group, 4 patients showed brain edema, presenting as sulcus and fissure flattened or disappeared, and ventricles and cisterns narrowed or closed 2-3 days after poisoning. In 3 patients 3 days to 3 months after poisoning, bilateral basal ganglion and cerebral cortex showed prolonged T 1 and T 2 signals, and high signal intensity was detected on FLAIR, and bilateral basal ganglion low density was revealed on CT. T 1 relaxation was shortened, T 2 WI and FLAIR imaging showed high signal intensity in 1 patient. The imaging of 1 patient 6 months after poisoning showed the cerebral sulcus, fissure and ventricle were enlarged. CT and MRI in the mild or moderate group were normal. By the Fisher's exact probabilities test, the imaging exhibition difference between the severe grade and mild or moderate grade patients was significant. Conclusion: The CT and MRI can reflect the brain injury after poisoning, and the imaging exhibitions were various. The imaging information can provide credible foundation for the therapy for lightening the brain edema and nourishing the brain cell

    2013-08-01

    Full Text Available Introduction: Acute exposure to pesticide due to suicidal poisoning is the most extensive cause of pesticide exposure, compared with all other causes including agricultural or industrial exposure. Organophosphate (OP and carbamate group of pesticides can inhibit acetylcholinesterase; on the other hand, paraoxonase1 can detoxify organophosphate poisoning by hydrolyzing organophosphate metabolites. Methods: We have compared the serum paraoxonase1 status and cholinesterase activity of subjects who attempted to commit suicide by consuming OP pesticide. Cholinesterase and paraoxonase1 activity were measured spectrophotometrically using butyrylthiocholine and phenyl acetate as substrates, respectively. Results: A positive correlation was found between serum paraoxonase1 activity and cholinesterase activity among pesticide consumed subjects. Conclusion: Our results suggest that subjects with higher paraoxonase1 activity may have a better chance of detoxifying the lethal effect of acute organophosphate poisoning.

    Understanding the epidemiologic profile of a particular disease is key to undertake health actions. To that end, information systems that present quality data help in the decision-making process and demonstrate the impact of the problems. To analyze the contribution of health information systems for the characterization of pesticide poisoning through SINAN, CEATOX and SIM in the State of Pernambuco. In this study, the completeness and consistency of the data were assessed, as well as the epidemiological profile of pesticide poisoning in Pernambuco in the period from 2008 to 2012, based on the following Health Information Systems: Center for Toxicological Assistance of Pernambuco (CEATOX), Notifiable Diseases Information System (SINAN) and Mortality Information System (SIM). The data revealed incompleteness and inconsistencies in information. Regarding the profile, females are more affected in the morbidity profile, and men have a higher mortality rate. Poisoning was more frequent in young adults with low educational level. With regard to the circumstances, most of the cases were suicide attempts, unique acute cases and not related to work. Despite suggesting underreporting, the data showed that persons engaged in agriculture are most commonly affected. The strengthening of these systems is necessary for the generation of consistent information that support health policies for the population groups involved.

    OBJECTIVES To determine the epidemiological profile and risk factors of voluntary poisoning by pesticides. METHODS A retrospective analysis was conducted of all cases of voluntary poisoning by pesticides registered at the AntiPoison and Pharmacovigilance Center of Morocco between January 2008 and December 2014. RESULTS During the study period, 2,690 cases of acute pesticide poisoning were registered. The region of Rabat-Salé-Zemmour-Zaer accounted for the largest proportion, with 598 cases. The average age of the patients was 24.63±10.29 years. The sex ratio (female-to-male) was 0.45. Adults and teenagers were most affected by this type of poisoning, with 1,667 cases (62.0%) and 806 cases (30.0%), respectively. Suicide attempts accounted for 98.4% of the cases (2,469 cases). Pesticide poisoning occurred more often in urban zones (64.8%). Insecticides were incriminated in 14.0% of cases, with a mortality rate of 4.2%. Among the 1,635 patients for whom the outcomes were known, 154 died, corresponding to a mortality rate of 5.7%. CONCLUSIONS Voluntary intoxication by pesticides presents a real scourge that affects public health, and in this study, we developed an epidemiological profile of this phenomenon. Nevertheless, this study has limitations in that it did not evaluate the impact of the socioeconomic and psychological factors that are important contributors to this type of poisoning.

    The purpose of this paper is to describe the epidemiological profile of acute pesticide poisoning in children (APP) treated by the Moroccan Poison Control Center (CAPM) and to analyze death cases in order to determine factors predictive of severity. the study is based on a retrospective study of all cases of APP collected by the CAPM over a period of eighteen years (January 1990 to December 2008). Univariate analysis was performed to identify risk factors. 2,672 cases of childhood poisoning by pesticide were collected. The mean age was 5.6 ± 4.57 years. The sex ratio was 1.12. The cause of poisoning was accidental in 87.1% of cases, followed by attempted suicide (12.1%). Organophosphates were the most frequent poison (50.7%), followed by alpha-chloralose (26.5%). The case fatality rate was 3.3%. Mortality was attributed to organophosphates in 30 cases, followed by inorganic derivatives (7 cases) and carbamates (6 cases). A univariate analysis comparing survivors and groups who died showed that rural origin (p = 0.04), voluntary circumstances (p = 0.001), and the type of chemical class of pesticide (p < 0.001) significantly influence fatal poisoning. Acute pesticide poisoning among children is a reality in Morocco. Preventive measures may be needed.

    Three hundred and seventy-six (67%) of 557 calves of approximately 150-200 kg live-weight died following subcutaneous injection of a solution containing 100 mg selenium as sodium selenite. Eight per cent of the 254 heifer calves and 56% of the 303 steers died. The calves had endured the stress of being weaned twice and held in stockyards twice as well as encountering wet weather during the 4 days before receiving the selenium. The heifer calves were also vaccinated with Br. abortus strain 19 vaccine at the same time as receiving the selenium. The clinical signs and pathological findings of circulatory failure and myocardial damage were similar to those previously reported in acute selenium poisoning.

    2013-01-01

    Full Text Available Organophosphorus compounds are used as pesticides and represent a common cause of poisoning in developing countries including India due to their widespread availability and use. Toxicity due to these agents can affect many organs including heart. Here, we report a case of acute organophosphorus poisoning (parathion, followed by acute myocardial infarction; documented by clinical features, electrocardiographic changes, and elevated cardiac enzymes. Myocardial infarction has been rarely reported with organophosphorus compounds exposure, thus awareness of this complication can reduce morbidity and mortality.

    Full Text Available Carbon monoxide poisoning is a major cause of death following attempted suicide and accidental exposures. Although clinical presentation depends on the duration and the intensity of exposure, the assessment of the severity of intoxication is difficult. A small percentage of patients who show complete initial recovery may develop delayed neurological deficits. Delayed encephalopathy after acute carbon monoxide poisoning is a rare and poor prognosis neurologic disorders and there is no specific treatment. We present a case with early onset of delayed encephalopathy after acute carbon monoxide poisoning with typical cranial imaging findings in a child with atypical history and clinical presentation.

    Poisoning by means of hazardous chemicals through ignorance, mishap or intentionally is becoming a serious health problem worldwide. Epidemiological data on this important health issue are, however, scarce in Ethiopia. The purpose of this study is to assess the pattern of acute poisonings and determine the approaches employed for the management of poisoning. The medical records of patients with acute poisonings presented to the Gondar University hospital between July 2001 and June 2004 were reviewed retrospectively. One hundred and two patients presenting to the emergency department of the hospital were due to acute poisoning; accounting for about 0.45% of emergency room admissions. Organophosphates, rat poison and alcohol were the commonly encountered poisoning agents (in about 70% of cases) mainly in adults possibly with suicidal or para-suicidal intention. The approaches employed in the management of poisoning mainly involved gastrointestinal decontamination procedures. Specific antidotes were used in a substantial number of patients. The fatality rate was 2.4%. Poisoning with suicidal intention is becoming a serious health problem particularly in adults. Pesticides are commonly used toxicants. The approaches in the management of poisoning are justifiable in some cases. However, much is to be done to improve the recording of patient-related information and record-keeping processes. Further large scale studies are required to investigate national trends of poisoning and factors associated with poisoning.

    Emamectin benzoate is the 4'-deoxy-4'-epi-methyl-amino benzoate salt of avermectin B1 (abamectin), which is similar structurally to natural fermentation products of Streptomyces avermitilis. Emamectin benzoate is being developed as a newer broad-spectrum insecticide for vegetables and has a very low application rate. The mechanism of action involves stimulation of high-affinity GABA receptors and a consequent increase in membrane chloride ion permeability. Animal studies indicate a wide margin of safety because mammalian species are much less sensitive due to lower GABA receptor affinities and relative impermeability of the blood-brain barrier. Notably, the literature has not reported human exposure resulting in toxicity. This paper describes a case of acute poisoning with Proclaim insecticide (Syngenta, Taiwan), consisting of 2.15% w/w emamectin benzoate in 2, 6-bis (1, 1-dimethylethyl)-4-methyl-phenol and 1-hexanol. The clinical manifestation was transient gastrointestinal upset with endoscopy-proven gastric erosion and superficial gastritis, mild central nervous system depression, and aspiration pneumonia. No specific antidote exists for emamectin benzoate intoxication; this patient was treated successfully with gastric lavage, administration of activated charcoal, and empiric antibiotics. Drugs that enhance GABA activity such as barbiturates and benzodiazepines were avoided.

    In parts of the developing world, pesticide poisoning causes more deaths than infectious diseases. Use of pesticides is poorly regulated and often dangerous; their easy availability also makes them a popular method of self-harm. In 1985, the UN Food and Agriculture Organisation (FAO) produced...... a voluntary code of conduct for the pesticide industry in an attempt to limit the harmful effects of pesticides. Unfortunately, a lack of adequate government resources in the developing world makes this code ineffective, and thousands of deaths continue today. WHO has recommended that access to highly toxic...... to do specific tasks within an integrated pest management system. Use of safer pesticides should result in fewer deaths, just as the change from barbiturates to benzodiazepines has reduced the number of deaths from pharmaceutical self-poisoning....

    Background Deliberate self-poisoning with agricultural pesticides is the commonest means of suicide in rural Asia. It is mostly impulsive and facilitated by easy access to pesticides. The aim of this large observational study was to investigate the immediate source of pesticides used for self-harm to help inform suicide prevention strategies such as reducing domestic access to pesticides. Methods The study was conducted in a district hospital serving an agricultural region of Sri Lanka. Patients who had self-poisoned with pesticides and were admitted to the adult medical wards were interviewed by study doctors following initial resuscitation to identify the source of pesticides they have ingested. Results Of the 669 patients included in the analysis, 425 (63.5%) were male; the median age was 26 (IQR 20-36). In 511 (76%) cases, the pesticides had been stored either inside or immediately outside the house; among this group only eight patients obtained pesticides that were kept in a locked container. Ten percent (n = 67) of the patients used pesticides stored in the field while 14% (n = 91) purchased pesticides from shops within a few hours of the episode. The most common reasons for choosing the particular pesticide for self-harm were its easy accessibility (n = 311, 46%) or its popularity as a suicide agent in their village (n = 290, 43%). Conclusion Three quarters of people who ingested pesticides in acts of self-harm used products that were available within the home or in close proximity; relatively few patients purchased the pesticide for the act. The study highlights the importance of reducing the accessibility of toxic pesticides in the domestic environment. PMID:19889236

    Paraquat is a highly effective contact herbicide that is marketed worldwide as a fantastical, non-selective compound for broadleaf weed control. As compared to most pesticides, paraquat is extremely toxic to humans and the lack of strategies to manage paraquat poisoning has resulted in high fatality rates. The rats were randomly divided into acute paraquat poisoning group and control group. The paraquat group rats were given 36 mg/kg paraquat by intragastric administration. The influence of a...

    To investigate the characteristics of pesticide poisoning in Jiangsu Province, China, and to provide a scientific basis for developing effective intervention measures and prevention strategies. The data from report cards of pesticide poisoning in Jiangsu Province from 2006 to 2013 were arranged using EXCEL tables, and assessed. Statistical analysis was applied to the epidemiological data using SPSS. From 2006 to 2013, a total of 32672 cases of pesticide poisoning were reported in Jiangsu Province. Most of the cases were caused by non-occupational poisoning (life poisoning) (72.78%). A majority of patients with pesticide poisoning were 35-54 years old (40.85%) or older than 65 years (15.69%). There were more female patients (58.22%) than male patients (41.78%). Among patients with occupational poisoning, male patients (50.90%) were more than female patients. Among patients with non-occupational poisoning, female patients were more than male patients (38.37%). Pesticide poisoning mainly occurred from July to September. The case-fatality rate of occupational poisoning (0.47%) was lower than that of non-occupational poisoning (7.10%). All 13 cities in Jiangsu Province reported cases of pesticide poisoning. There were more cases in the northern regions than in the southern regions. Pesticide poisoning was mainly caused by organophosphorus insecticides including methamidophos, dichlorvos, dimethoate, omethoate, and parathion, which accounted for 65.58%of all cases. Paraquat had the highest case-fatality rate (10.06%) among all pesticides, followed by tetramine (10.00%), dimethoate or omethoate (7.85%), methamidophos (7.79%), and dimehypo (7.68%). Pesticide poisoning cannot be ignored. The management and control should be improved in production and usage of highly toxic pesticides including organophosphorus insecticides, rodenticides, and herbicides. More attention should be paid to the protection of vulnerable groups including women, children, and the elderly.

    Full Text Available Abstract Background In South Asia, up to 20% of people ingesting pesticides for self-poisoning purchase the pesticide from a shop with the sole intention of self-harm. Individuals who are intoxicated with alcohol and/or non-farmers represent 72% of such high-risk individuals. We aimed to test the feasibility and acceptability of vendor-based restrictions on pesticide sales for such high-risk individuals. Methods We conducted a pilot study in 14 (rural = 7, urban = 7 pesticide shops in Anuradhapura District of Sri Lanka. A two-hour training program was delivered to 28 pesticide vendors; the aim of the training was to help vendors recognize and respond to customers at high risk of pesticide self-poisoning. Knowledge and attitudes of vendors towards preventing access to pesticides for self-poisoning at baseline and in a three month follow-up was evaluated by questionnaire. Vendors were interviewed to explore the practice skills taught in the training and their assessment of the program. Results The scores of knowledge and attitudes of the vendors significantly increased by 23% (95% CI 15%–32%, p < 0.001 and by 16% (95% CI 9%–23%, p < 0.001 respectively in the follow-up. Fifteen (60% vendors reported refusing sell pesticides to a high-risk person (non-farmer or intoxicated person in the follow-up compared to three (12% at baseline. Vendors reported that they were aware from community feedback that they had prevented at least seven suicide attempts. On four identified occasions, vendors in urban shops had been unable to recognize the self-harming intention of customers who then ingested the pesticide. Only 2 (8% vendors were dissatisfied with the training and 23 (92% said they would recommend it to other vendors. Conclusions Our study suggests that vendor-based sales restriction in regions with high rates of self-poisoning has the potential to reduce access to pesticides for self-poisoning.

    Full Text Available Most publications report on the use of methadone as a medication, however an increase of the illegal use of methadone has been demonstrated worldwide over the recent years, thus increasing the number of hospitalizations due to acute poisoning with this synthetic opioid. The aim of the present review was to summarize current data on the mechanisms of toxicity, selective toxicity, toxicokinetics and toxicodynamics of methadone (Dolphin. The involvement of CNS, respiratory, cardiovascular and urinary systems in acute poisoning with methadone was dis- cussed. The practice of use of methadone in many countries as a medicine for the replacement therapy for opiate addicts was analyzed. In addition, it was suggested that the results of the use of naloxone antidote therapy in acute opioid poisoning do not always clearly demonstrate its sufficient efficacy. Ways to improve of the intensive therapy of severe acute poisoning by methadone were substantiated; in addition to general critical care methods, treatment with a complex metabolic antihypoxant cytoflavin should be considered.

    To compare the acute-poisoning characteristics between city and rural areas of Guangxi Province in order to provide clinical data for the formation of treatment strategies of acute poisoning in Guangxi. Data of acute poisoning patients as treated in 36 municipal and 12 county hospitals, and also 15 rural clinics in 11 cities of Guangxi during 2005 to 2009 were collected and analyzed according to poisoning population, poisoning site, poisoning process, and poisoning degree. By analysing 3678 and 2153 cases of acute poisoning patients in rural and urban areas, the gender [χ (2) = 5.53, P old (11.17% vs. 8.69%), farmers by occupation (74.84% vs. 2.79%), home (80.64% vs. 78.07%), sites of labor (11.83% vs. 3.07%) and other sites (4.08% vs. 2.97%), and the chief causes were professional (3.10% vs. 1.30%), taken by mistake (21.85% vs. 20.91%), homicide (0.30% vs. 0.28%), and suicide (39.07% vs. 18.77%), and by pesticide (60.94% vs. 12.13%), plant (7.08% vs. 2.88%) and animal poisons (7.73% vs. 6.56%), belonging to severe poisoning (25.86% vs. 19.04%) were higher than those in town. In the town, poisoning occurred predominantly in female (55.09% vs. 51.90%), age below 19 years old (23.78% vs. 19.44%), unemployed (33.35% vs. 13.76%), student (17.53% vs. 8.43%), industrial workers (31.95% vs. 2.69%), executives (10.84% vs. 0.22%) and other professional (3.53% vs. 0.05%); occurred in schools (8.78% vs. 0.82%), restaurants (5.48% vs. 1.55%), place of entertainment (1.63% vs. 1.09%), by accidental (52.23% vs. 31.27%), therapeutic (4.46% vs. 2.56%), and other reasons (2.04% vs. 1.85%); by chemicals (33.19% vs. 8.55%), medicines (24.31% vs. 9.12%), and other types of poison (20.92% vs. 6.59%); light and medium degree of poisoning (44.87% vs. 41.22%, 36.09% vs. 32.93%) were higher than those in rural areas.

    This descriptive and retrospective study was conducted at the poisoning ward of Imam teaching hospital, Sari, Iran, with the aim of evaluating the pattern of poisoning. Hence, the medical profiles of 2057 patients, who were admitted, were carefully reviewed during the period from April 2006 to March 2008 for 2 years. During this period, 2057 cases, 53.9% female and 46.1% male, were admitted with the indication of acute poisoning. The greatest proportion of poisoning occurred between the ages of 18 and 29 years, with suicidal intentions. Most cases of poisoning were intentional (85%). The most common agents involved in acute poisoning were drugs (77.7%), especially sedatives/hypnotics such as benzodiazepines, followed by opioid analgesics. Organophosphate and carbamate insecticides were the third major agent that induced poisoning. Twenty-seven patients (1.3%) who were mostly females and young adults died. Death mostly occurred due to organophosphate and carbamate insecticides (19 cases) poisoning, followed by sedatives/hypnotics like benzodiazepines (3 cases). High prevalence of intentional overdose and mortality among young adults requires considerable attention and further studies to find out the underlying causes. In addition, strict rules must be followed regarding the sale of central nervous system drugs and pesticides, particularly organophosphate and carbamate insecticides. Establishing poison information centers in different parts of the country, preparing national treatment guidelines, training healthcare providers, and ensuring easy availability of the antidotes are also recommended.

    Introduction Pediatric poisonings represent a major and preventable cause of morbidity and mortality throughout the world. Epidemiologic information about poisoning among children in many lower- and middle-income countries is scarce. This study describes the epidemiology of acute poisonings in children presenting to Ain Shams University's Poisoning Treatment Center (ASU-PTC) in Cairo and determines the causative agents and characteristics of acute poisoning in several pediatric age groups. Methods This retrospective study involved acutely poisoned patients, 0 to 18 years of age, who presented to the ASU-PTC between 1/1/2009 and 12/31/2013. Data were extracted from electronic records maintained by the ASU-PTC. Collected data included demographics, substance of exposure, circumstances of the poisoning, patient disposition, and outcome. Results During the 5-year study period, 38,470 patients meeting our criteria were treated by the ASU-PTC; 19,987 (52%) were younger than 6 years of age; 4,196 (11%) were 6 to 12 years; and 14,287 (37%) were >12 years. Unintentional poisoning accounted for 68.5% of the ingestions, though among adolescents 84.1% of ingestions were with self-harm intent. In all age groups, the most frequent causative drugs were non-opioid analgesics, antipyretics, and antirheumatics. The most common nonpharmaceutical agents were corrosives in preschool children and pesticides in adolescents. Most patients had no/minor effects (29,174 [75.8%]); hospitalization rates were highest among adolescents. There were 119 deaths (case fatality rate of 0.3), primarily from pesticide ingestion. Conclusion Poisoning in preschool children is mainly unintentional and commonly due to nonpharmaceutical agents while poisoning in adolescents is mainly intentional (self-harm). Pesticides, mainly organophosphorous compounds and carbamates, were the most frequent agent leading to morbidity and mortality. PMID:26653953

    2014-07-01

    We report a case of 30 year old alcoholic male admitted with vomiting, drowsiness, limb weakness and fasciculations after alleged history of consumption of 30 ml of chlorpyriphos insecticide. He had low serum cholinesterase levels. With standard treatment for organophosphorus poisoning (OPP), he improved gradually until day 5, when he developed neck and limb weakness and respiratory distress. This intermediate syndrome was treated with oximes, atropine and artificial ventilation. During treatment, his ECG showed fresh changes of ST elevation. High CPK & CPK-MB levels, septal hypokinesia on 2D echo suggested acute coronary syndrome. Coronary angiography was postponed due to his bedridden and obtunded status. The patient finally recovered fully by day 15 and was discharged. Acute coronary syndrome is a rare occurrence in OP poisoning. The present case thus emphasises the need for careful electrocardiographic and enzymatic monitoring of all patients of organophosphorus poisoning to prevent potential cardiac complication which can prove fatal.

    Acute thallium poisoning rarely occurs but is a serious and even fatal medical condition. Currently, patients with acute thallium poisoning are usually treated with Prussian blue and blood purification therapy. However, there are few studies about these treatments for acute thallium poisoning. Nine patients with acute thallium poisoning from 1 family were treated successfully with Prussian blue and different types of blood purification therapies and analyzed. Prussian blue combined with sequential hemodialysis, hemoperfusion and/or continuous veno-venous hemofiltration were effective for the treatment of patients with acute thallium poisoning, even after delayed diagnosis. Blood purification therapies help in the clearance of thallium in those with acute thallium poisoning. Prussian blue treatment may do the benefit during this process.

    Full text: There are some difficulties in making early diagnosis on acute radioactive poisoning. Clinical disorders from a poison in November 2006 in London has not given an opportunity to doctors to reveal radiation as the reason of the acute injury before the death. The report purpose is to give more diagnostic possibilities to reveal early signs of acute radioactive poisoning. It provides an evaluation of clinical observation data on a difference of clinical symptoms after internal or external exposure, activities of some radioactive isotopes that are able to cause ARS with bone marrow failure or damages to different organs and tissues. The report contains descriptions of some clinical cases of radioactive poisonings. Prodromal responses after acute internal expose are significant only in cases of the following early death but are not typical for the most clinical cases of internal exposure. Lethal gastrointestinal or cutaneous damages are not characteristic. Early radiation vasculitis (blood vessel endotheliitis) sings: bloody rash on the trunk, blood in the urine, hemorrhages in the skin and mucous membranes at blood platelet count in excess of 40 x 10 9 l -1 . Death from lung radiation injury could be expected in all individuals from as little as 7 MBq of inhaled alpha emitter with energy of about 5 MeV and an effective half-life greater than 100 days. Death from severe bone marrow syndrome for the first month or death from liver insufficiency for the following 6 months is typical after ingestion or injection of radioactive materials at lethal doses. Hemolytic sings after acute exposure should be confirmed by the following clinical investigations. It is known the erythrocyte hemolysis and the following hemoglobin decay is a significant source of the endogenous CO that release from the hem. So estimation of CO and methemoglobin in the blood is a way for revealing of the higher erythrocyte destroy. If hemolytic syndrome is characteristic for early acute

    Full Text Available Objective: to evaluate the efficiency of methods for diagnosing and treating critically ill patients with acute respiratory failure (ARF in acute poisoning by neurotropic substances. Subjects and methods. Two hundred and thirty-three patients with acute severe intoxication with neurotropic poisons were examined. All the patients were admitted for toxic-hypoxic coma and ARF; in this connection all the patients underwent artificial ventilation (AV. The patients were divided into 3 groups: 1 those in whom the traditional treatments (AV, detoxifying therapy, and infusional and cardiotropic support could restore the basic parameters of vital functions, as judged from the recovered oxygenation index; these patients had no metabolic shifts; 2 those who had signs of pulmonary hyperhydration, low cardiac output and moderate metabolic disorders, as suggested by elevated lactate levels; 3 seriously ill patients in whom the interval between the time of poisoning to care delivery was more than 20 hours; the patients of this group had the most significant metabolic disorders. Results. Correction of ARF in critically ill patients with acute poisoning should include, in addition to the rational parameters of AV and detoxifying therapy, agents for targeted therapy for sequels of hypoxia and energy deficiency states. For maximally rapid and effective oxygen transport recovery, the addition of perfluorane to the complex therapy cardinally improves the results of treatment and reduces mortality rates. Conclusion. The complexity of the pathogenesis of ARF and its sequels is a ground for diagnosing and correcting not only ventilation disturbances, but also pulmonary microcirculatory disorders and metabolic disturbances. Key words: acute intoxication with neu-rotropic poisons, acute respiratory failure, pulmonary hyperhydration, hypoxia, metabolic disturbances.

    Full Text Available Acute poisonings are a frequent complaint in emergency departments and therapy which prevents the absorption of toxic products taken orally is often indicated: one such option is gastric lavage. Gastric lavage is a digestive decontamination technique whose goal is to remove the maximum amount of poison from the stomach and prevent its absorption. The procedure involves inserting a gastric tube into the stomach through the mouth or nose; firstly to aspirate all the stomach contents and then to perform gastric washing manoeuvres. The effectiveness of gastric lavage is limited and involves a risk of iatrogenesis, and therefore the indications and contraindications should be carefully considered and the technique carried out meticulously to increase its effectiveness and reduce complications, primarily bronchoaspiration. Gastric lavage may be used in conjunction with other digestive decontamination techniques such as administration of activated charcoal. This gastric lavage protocol is based on a review of the literature on this procedure and is supported by the expertise of our research group in gastrointestinal decontamination techniques in patients with acute poisoning.

    Organophosphorus compounds (OPCs) have a wide variety of applications and are a serious threat for self-poisoning, unintentional misuse, terrorist attack, occupational hazard and warfare attack. The present standard treatment has been reported to be unsatisfactory. Many novel approaches are being used and tested for acute organophosphorus (OP) poison treatment. The bioscavenger concept captured high attention among the scientific community during the last few decades. Other approaches like alkalinisation of blood plasma/serum and use of weak inhibitors against strong inhibitors, though it showed promising results, did not get such wide attention. The introduction of a novel broad-spectrum oxime has also been in focus. In this mini-review, an update of the overview of four different approaches has been discussed. The standard therapy that is atropine+oxime+benzodiazepine along with supportive measures will continue to be the best option with only the replacement of a single oxime to improve its broad-spectrum efficacy.

    To describe the chest radiographic findings of acute paraquat poisoning. 691 patients visited the emergency department of our hospital between January 2006 and October 2012 for paraquat poisoning. Of these 691, we identified 56 patients whose initial chest radiographs were normal but who developed radiographic abnormalities within one week. We evaluated their radiographic findings and the differences in imaging features based on mortality. The most common finding was diffuse consolidation (29/56, 52%), followed by consolidation with linear and nodular opacities (18/56, 32%), and combined consolidation and pneumomediastinum (7/56, 13%). Pleural effusion was noted in 17 patients (30%). The two survivors (4%) showed peripheral consolidations, while the 54 patients (96%) who died demonstrated bilateral (42/54, 78%) or unilateral (12/54, 22%) diffuse consolidations. Rapidly progressing diffuse pulmonary consolidation was observed within one week on follow-up radiographs after paraquat ingestion in the deceased, but the survivors demonstrated peripheral consolidation.

    Full Text Available Aluminium phosphide (AlP is a cheap solid fumigant and a highly toxic pesticide that is commonly used for grain preservation. AlP has currently generated interest with increasing number of cases in the past four decades because of its increased use for agricultural and nonagricultural purposes, and also its easy availability in the markets has led to its increased misuse to commit suicide. Ingestion is usually suicidal in intent, uncommonly accidental and rarely homicidal. The poison affects all systems, shock, cardiac arrhythmias with varied ECG changes and gastrointestinal features being the most prominent. Diagnosis is made on the basis of clinical suspicion, a positive silver nitrate paper test to phosphine, and gastric aspirate and viscera biochemistry. Treatment includes early gastric lavage with potassium permanganate or a combination of coconut oil and sodium bicarbonate, administration of charcoal and palliative care. Specific therapy includes intravenous magnesium sulphate and oral coconut oil. Unfortunately, the lack of a specific antidote Results in very high mortality and the key to treatment lies in rapid decontamination and institution of resuscitative measures. This article aims to identify the salient features and mechanism of AlP poisoning along with its management strategies and prognostic variables.

    We report a patient who ingested about 13 g of Padan SG, a cartap-containing pesticide. After ingestion, the patient developed multiple seizures and dyspnea and lost consciousness. The patient did not recover and died on the fifth hospital day despite treatment at the early stage of poisoning. The cause of death was multisystem organ failure. Results of toxicological analysis were as follows: concentrations of nereistoxin (cartap metabolite) were 10.6 microg/mL in plasma, 18.2 microg/mL in urine, and 2.6 mg/mL in gastric fluid. Results of drug screening of urine by Triage DOA Panels and using an organophosphate detection kit were negative.

    years. New potential therapeutic agents for OPI poisoning include: glycopyrrolate as anticholinergic; organophosphorous hydrolases, butyrilcholinesterases and sodium bicarbonate which degrade OPI and accelerate AChE reactivation; reversible anticholinesterases for reduction of AChE reinchibition; NMDA antagonist as neuroprotectors. Authors from Maryland have proposed the usage of IL-1 Rp antagonists in acute OPI intoxication, a new, original approach to therapy which deserves to be elucidated. For now pharmaceutical industries do not show satisfying initiative in developing new therapeutic agents and antidotes for OPI poisoning. However, randomized, controlled clinical studies, for the beginning with the agents which are in clinical practice, would elucidate their clinical efficacy, reduce the number of lethal pesticide poisonings in developing countries and provide information of special importance for the army and medical service.

    Full Text Available Poisoning is a frequent cause of referral to medical emergencies and a major health problem around the world, especially in developing countries. We aimed to review the epidemiology and pattern of adult poisoning in Iran in order to facilitate the early diagnosis and management of poisoning. The pattern of poisoning is different in various parts of Iran. Pharmaceutical compounds were the most common cause of poisoning in most parts of Iran. Pesticide-related toxicities were more common in northern agricultural regions, whereas bites and stings were seen more commonly in southern Iran. Carbon monoxide poisoning was common in cities with many motor vehicles such as Tehran and in colder climates such as in northern and western regions due to inadequately vented gas appliances such as stoves and heaters. Majoon Birjandi (containing cannabis is a unique substance used in eastern Iran. Poisoning by opioids, tramadol, and pesticides (organophosphate and aluminum phosphide has remained a common hazard in Iran. Poisoning-associated morbidity and mortality rates vary by region and have changed over time due to the introduction of new drugs and chemicals. Early diagnosis and proper treatment may be lifesaving; thus, understanding the general pattern of poisoning in different regions is important.

    1,2,3-trichloropropane (1,2,3-TCP) is commonly used as an intermediate in pesticide and an industrial specialty solvent. Acute 1,2,3-TCP poisoning is rare but a medical emergency. Sporadic cases of toxic hepatic injury from 1,2,3-TCP in humans have been reported. Liver is a target organ for 1,2,3-TCP toxicity, which may ensue in a short period after ingestion. A specific antidote against 1,2,3-TCP is not available. So it is important to distinguish that a patient with 1,2,3-TCP poisoning constitutes a medical emergency. In this case study, the poisoned patient's clinical condition and laboratory values improved gradually after she received hemoperfusion (HP) and plasma exchange, which indicated that the therapy with HP and plasma exchange were helpful in the treatment of 1,2,3-TCP poisoning.

    Full Text Available BACKGROUND Poisoning is a global public health problem causing significant morbidity and mortality. It is important to know the pattern and outcome of acute poisoning cases for proper planning, prevention and management of these cases. The aim of the study is to determine the mode (suicidal, accidental, homicidal and type of poisoning in North Indian population; relation to age, sex, occupation, marital status; outcome of different type of poisons and requirement of ventilatory support in different type of poisonings. MATERIALS AND METHODS This observational study was conducted in Department of Medicine of a tertiary care hospital in North India. A total of 379 patients were enrolled in the study after obtaining informed consent. RESULTS Poisoning was more common among males (59.89%. Maximum number of patients were in the age group 21-30 years (40.63% and consumption was found to be more prevalent in rural population (75.99%. Most of the patients were farmers and students. Most common types of poisoning were organophosphate (n=95, 25.07%, snake bite (n=77, 20.32% followed by aluminium phosphide (n=71, 18.73%. Out of 379 patients, 318 (83.91% improved while 61 (16.09% expired. Mortality was highest in aluminium phosphide poisoning. Requirement of ventilatory support was most commonly associated with aluminium phosphide poisoning (37.89% followed by organophosphate poisoning (28.42%. CONCLUSION Poisoning was more common in young males. Pesticides and snake bite were major causes of poisoning. Of the total, 318 improved while rest of the 61 expired. Mortality was higher with use of aluminium phosphide poisoning (57.38%, snake bite (21.31% and organophosphate consumption (9.84%. Requirement of ventilator was most commonly associated with aluminium phosphide poisoning. We suggest strict statutory measures covering import, manufacture, sale, transport, distribution and use of pesticides. Training of peripheral health center personnel to manage cases

  13. Predictive acute toxicity tests with pesticides.

    Science.gov (United States)

    Brown, V K

    1983-01-01

    By definition pesticides are biocidal products and this implies a probability that pesticides may be acutely toxic to species other than the designated target species. The ways in which pesticides are manufactured, formulated, packaged, distributed and used necessitates a potential for the exposure of non-target species although the technology exists to minimize adventitious exposure. The occurrence of deliberate exposure of non-target species due to the misuse of pesticides is known to happen. The array of predictive acute toxicity tests carried out on pesticides and involving the use of laboratory animals can be justified as providing data on which hazard assessment can be based. This paper addresses the justification and rationale of this statement.

Retrospective descriptive study of acute poisonings treated in the Emergency Service of the University Hospital of Zaragoza from 1995 to 2009 on patients 65 years old or older. A total of 762 patients were selected in the study (4.74% of all acute poisonings) with a mean age of 74.16 (SD ± 6) years. Ingestion was the major route of exposure (85%) and alcohol overdose (28,7%) was the most frequent type of poisoning. A trend was also observed showing a lower emetic treatment and gastric lavage and an increase in activated charcoal. Benzodiazepines (14.3%) and toxic household products (11%) with caustic properties were also the main toxics found in the study. Acute poisonings in the elderly required more hospitalizations, have a higher mortality and more autolytic attempts which result in death.

    Full Text Available Abstract Background Evidence is accumulating that pesticide self-poisoning is one of the most commonly used methods of suicide worldwide, but the magnitude of the problem and the global distribution of these deaths is unknown. Methods We have systematically reviewed the worldwide literature to estimate the number of pesticide suicides in each of the World Health Organisation's six regions and the global burden of fatal self-poisoning with pesticides. We used the following data sources: Medline, EMBASE and psycINFO (1990–2007, papers cited in publications retrieved, the worldwide web (using Google and our personal collections of papers and books. Our aim was to identify papers enabling us to estimate the proportion of a country's suicides due to pesticide self-poisoning. Results We conservatively estimate that there are 258,234 (plausible range 233,997 to 325,907 deaths from pesticide self-poisoning worldwide each year, accounting for 30% (range 27% to 37% of suicides globally. Official data from India probably underestimate the incidence of suicides; applying evidence-based corrections to India's official data, our estimate for world suicides using pesticides increases to 371,594 (range 347,357 to 439,267. The proportion of all suicides using pesticides varies from 4% in the European Region to over 50% in the Western Pacific Region but this proportion is not concordant with the volume of pesticides sold in each region; it is the pattern of pesticide use and the toxicity of the products, not the quantity used, that influences the likelihood they will be used in acts of fatal self-harm. Conclusion Pesticide self-poisoning accounts for about one-third of the world's suicides. Epidemiological and toxicological data suggest that many of these deaths might be prevented if (a the use of pesticides most toxic to humans was restricted, (b pesticides could be safely stored in rural communities, and (c the accessibility and quality of care for poisoning

    The role of pesticides in suicidal acts has not yet received adequate attention in Greece despite an evident rise of 39% in pesticide use over the period 1990-1992 to 2002-2004. To investigate the epidemiology of pesticide suicide on the Greek island of Crete, a largely rural agricultural area, and by further exploring the victim profiles, as well as patterns and trends of pesticide ingestion, to suggest probable preventive measures. Self-poisoning suicides between 1999 and 2007 were reviewed and information gathered was entered into a computerized database. The overall incidence of intentional pesticide poisoning was 1.7 per 100,000, representing the second most frequently used suicide method after hanging. The victim profile was composed of the following features: middle aged male, rural habitant, who carried out a suicidal act by consuming primarily methomyl or paraquat (WHO toxicity class Ib and class II, respectively). As to the place of death, the vast majority was found dead in the place of intoxication. Pesticide self-poisoning accounts for a quarter of the suicides in Crete. More detailed research is required to identify aspects of these deaths amenable to prevention, but measures such as bans on the most toxic pesticides and changes in storage practice would appear to be sensible initial approaches.

    Full Text Available During a six-year period (from January 2009 to December 2014, specimens collected from 344 cases of suspected organophosphorus and carbamate pesticide poisonings in wildlife, including birds, were submitted to the Toxicology Laboratory (ARC-OVI for analysis. A positive diagnosis was made in 135 (39% of these cases. The majority of cases were from birds, which included Cape vultures (Gyps coprotheres and African white-backed vultures (Gyps africanus and bateleur eagles (Terathopius ecaudatus. In one incident 49 vultures were killed when a farmer intentionally laced carcasses with carbofuran in an attempt to control jackal predation. There were 22 incidents of poisoning in helmeted guineafowl (Numida meleagris. On nine different occasions blue cranes (Anthropoides paradiseus were poisoned, in one incident 14 birds were reported to have been killed. Over the period of investigation, there were 20 cases of poisoning involving mammalian species, the majority being vervet monkeys (Chlorocebus pygerythrus. The carbamate pesticides were responsible for 57 incidents of poisoning. Aldicarb, carbofuran and methomyl were detected in 26, 18 and 12 cases respectively. The majority of organophosphorus pesticide poisonings were caused by diazinon (n = 19, monocrotophos (n = 13 and methamidophos (n = 10.

    Lithium continues to be the treatment of choice for bipolar disorder. Acute lithium poisoning is a potentially serious event. We present a retrospective observational significative study of episodes of acute lithium poisoning during a 52- month period. Poisoning was defined by a blood lithium concentration of 1.5 mEq/L or higher. We analyzed treatment and epidemiologic and clinical characteristics of 70 episodes were identified (incidence density among treated patients, 1.76 per 100 patient-years). The most frequent cause of lithium poisoning was a concurrent medical condition (46%). Most poisonings were mild (74.2%), but neurologic involvement was identified in 40.3%. Electrocardiographic abnormalities were found in 8 cases. Acute renal failure, found in 23 patients (37.1%), was mild in most cases, although 11 patients required hemodialysis. We concluded that acute lithium poisoning is an uncommon complication, but risk needs to be lowered. Patients should be warned to avoid dosage errors and to take special care during concurrent illnesses and while taking other medications.

    Hexogen (cyclonite, RDX) nitrate explosive is an infrequent cause of poisoning. A 42-year-old man with no prior history of epilepsy experienced grand mal seizures after sieving fine hexogen (RDX) powder for four hours in an ammunition plant. Physical examination was normal on arrival at the emergency room but recurrent seizures occurred six hour after admission. EEG, CT scan and MRI were normal and the patient recovered uneventfully. The available toxicological data on this rare occupational poisoning are reviewed.

    Organophosphates are commonly used pesticides and cause about one million unintentional and 2 million suicidal exposures with up to 300,000 fatalities every year around the world. Toxicity of organophosphates is due to inhibition cholinesterase activity and prolonging the effects of acetylcholine in the receptor site. Clinical features of organophosphate poisoning are defecation, urination, miosis, bronchorrhea, emesis, lacrimation and salivation. Spontaneous abortion reported some when in pregnant patients. Intravenous administration of benzodiazepines, atropine and pralidoxime is the formal treatment of this toxicity. Atropine and pralidoxime have been assigned to pregnancy class C by the FDA and should be recommended for use in pregnant women clinically suffer organophosphate poisoning. Benzodiazepines have been assigned to pregnancy class D and should be avoided during pregnancy. Clinical experiments suggest transplacental transfer of organophosphates is possible, and fetal sensitivity is probable, but a single acute overdose most likely don't make any physical deformities, therefore termination of pregnancy is not imperative. Nonetheless, no definite strategy focused on maintaining pregnancy. Here we propose an idea that in any female case of acute organophosphate poisoning in childbearing range of age, maternal serum Beta-HCG should be tested for pregnancy and prophylactic progesterone should be used in pregnant cases of organophosphate poisoning.

    Full Text Available Objective To study the applied value of modified poisoning severity score (PSS for early prognostic evaluation in acute paraquat poisoning. Methods Thirty-seven patients with acute paraquat poisoning from June 2013 to June 2016 were enrolled. The PSS score, the modified PSS score, the acute physiology and the chronic health status Ⅱ score (APACHE Ⅱ of the patients were calculated. The relationship between modified PSS and APACHE Ⅱ was analyzed. Also the factors that affect outcome were analyzed by logistic regression analysis. The work characteristic curve (ROC curve of the PSS, the modified PSS and the APECH Ⅱ were drawn and compared. Results There was a positive correlation between the risk of death and admission time, poisonous dose, the concentration of urine paraquat, and white blood cell count (P<0.05. There was a significant correlation between the modified PSS and the APACHE Ⅱ(P<0.0001. The immediate PSS score, the modified PSS score, and the APACHE Ⅱ score were significant for the prognosis of patients with acute paraquat poisoning. The area under the curve (AUC was in turn 0.774, 0.788, 0.799. Among them, the best bound of the modified PSS score was 6.5 (when the score is greater than 6.5, the risk of death is higher. Further comparison of the area under the three curves showed that there was no significant difference in the area under the ROC curve between the three scores in predicting the prognosis of death [P=0.7633(PSS-DPSS, P=0.7791(PSS-APACHE Ⅱ, P=0.8918(DPSS-APACHE Ⅱ]. Conclusion Modified PSS is helpful in early predicting the prognosis of acute paraquat poisoning. DOI: 10.11855/j.issn.0577-7402.2018.04.13

  14. Acute occupational poisoning by octogen: first case report.

    Science.gov (United States)

    Testud, François; Descotes, Jacques; Le Meur, Brigitte

    2006-01-01

    Octogen (HMX) is a polynitramine explosive closely related to hexogen, a known occupational toxin in military munitions plants. No acute human poisoning with octogen has ever been reported. A 28-year-old man with no history of epilepsy was admitted to the Emergency Department for seizures that had developed during the night after a full working day when he manually sieved large amounts of dry octogen. On admission, the clinical examination was normal and all other examinations could not substantiate the development of essential or secondary epilepsy. Elevated octogen concentrations were measured in his plasma, which confirmed occupational exposure to the explosive. The rarity of acute human poisonings by octogen is due to the infrequent use of this explosive and, more importantly, its very low oral bioavailability. However, acute poisoning can occur, but should be easily avoided by implementing adequate preventive measures.

    Method: A retrospective review of patients’ records was conducted and included patients treated from January 2004 to December 2005. Data on the demographic status of the patients, information about the poisonous agent(s involved, and the circumstances and outcomes of the poisoning incidents were recorded on a pre-tested data collection form. Results: A total of 590 cases of acute poisoning were included in the analysis. The most affected age category was that of children aged less than six years, who constituted 33.4% of the cases. Most incidents were recorded in the urban district of Gaborone. Seventy-eight percent (78% of the incidents were accidental, with the remainder being intentional. The poisonous agents involved were pharmaceuticals (26.6%, natural toxins (25.6%, household products (14.6%, foods (14.4%, alcohol (6.9%, traditional medicines (4.7%, unspecified agents (3.2%, and agrochemicals (2.7%. The most common route of poison exposure was by oral (82.2%, followed by dermal contact (16.5%, while the inhalation of gases occurred in 1.2% of cases. An incidence rate of 4.7/1000, a case fatality rate of 3.8/100, and 1.5% of deaths were recorded over the two-year period. Conclusion: In conclusion, it can be stated that acute poisoning involved mainly young children and resulted in an incidence rate of 4.7/1000, a case fatality rate of 3.8/100, and 1.5% of deaths over the two-year period. There were differences based on age category, gender and residence of the victims, the types of toxic agents involved, as well as the circumstances and the outcomes of the poisoning incidents. Given the fact that pharmaceuticals, natural toxins, household products and foods were the agents most commonly involved, targeted interventions should take these differences into account in addressing the problem of acute poisoning.

    Identifying international differences in the management of acute pediatric poisonings may help improve the quality of care. The objective of this study was to assess the international variation and appropriateness of gastrointestinal decontamination (GID) procedures performed in children and adolescents who present with acute poisonings to emergency departments. This was an international, multicenter, cross-sectional prospective study including children poisoning exposures presenting to 105 emergency departments in 20 countries from 8 global regions belonging to the Pediatric Emergency Research Networks. Data collection started between January and September 2013 and continued for 1 year. The appropriateness of GID procedures performed was analyzed using the American Academy of Clinical Toxicology and the European Association of Poisons Centres and Clinical Toxicologists' recommendations. Multivariate logistic regression was performed to identify independent risk factors for performing GID procedures. We included 1688 patients, 338 of whom (20.0%, 95% confidence interval 18.1%-22.0%) underwent the following GID procedures: activated charcoal (166, 49.1%), activated charcoal and gastric lavage (122, 36.1%), gastric lavage (47, 13.9%), and ipecac (3, 0.9%). In 155 (45.8%, 40.5%-51.2%), the GID procedure was considered appropriate, with significant differences between regions. Independent risk factors for GID procedures included age, toxin category, mechanism of poisoning, absence of symptoms, and the region where the intoxication occurred ( P management of pediatric poisonings.

    Background Poisoned patients are often treated in and discharged from pre-hospital health care settings. Studies of poisonings should therefore not only include hospitalized patients. Aims: To describe the acutely poisoned patients treated by ambulance personnel and in an outpatient clinic; compare patients transferred to a higher treatment level with those discharged without transfer; and study the one-week mortality after pre-hospital discharge. Methods A one-year multi-centre study with prospective inclusion of all acutely poisoned patients ≥ 16 years of age treated in ambulances, an outpatient clinic, and hospitals in Oslo. Results A total of 3757 health service contacts from 2997 poisoning episodes were recorded: 1860 were treated in ambulances, of which 15 died and 750 (40%) were discharged without transfer; 956 were treated in outpatient clinic, of which 801 (84%) were discharged without transfer; and 941 episodes were treated in hospitals. Patients discharged alive after ambulance treatment were mainly poisoned by opiates (70%), were frequently comatose (35%), had respiratory depression (37%), and many received naloxone (49%). The majority of the patients discharged from the outpatient clinic were poisoned by ethanol (55%), fewer were comatose (10%), and they rarely had respiratory depression (4%). Among the hospitalized, pharmaceutical poisonings were most common (58%), 23% were comatose, and 7% had respiratory depression. Male patients comprised 69% of the pre-hospital discharges, but only 46% of the hospitalized patients. Except for one patient, who died of a new heroin overdose two days following discharge from an ambulance, there were no deaths during the first week after the poisonings in the 90% of the pre-hospital discharged patients with known identity. Conclusion More than half of the poisoned patients treated in pre-hospital treatment settings were discharged without transfer to higher levels. These poisonings were more often caused by drug and

    Full Text Available Background: Identification of regional pattern of poisoning is essential for health care authorities for proper planning on prevention programs and optimized management of antidote stockpiles. This study was designed to evaluate one-year epidemiologic pattern of acute poisoning cases treated at a tertiary care hospital in Thrissur, India. Methods: In this retrospective cross sectional study, medical records of patients with the diagnosis of acute pharmaceutical and chemical poisoning admitted to Jubilee Mission Hospital (JMH, during 1st October 2012 to 30th September 2013 were reviewed. Results: During the study period, 168 poisoned patients (59.5% women were treated at emergency department of JMH. Married patients outnumbered unmarried ones (55.4% vs. 44.6%. The highest number of patients aged 21 to 30 years (31.5% followed by patients with 11-20 years of age (17.3%. Most of the poisonings occurred following suicidal ideation (72.6%. Familial disharmony (14.3% was the most common reason behind suicidal ingestions, followed by mental disorders (11.3%. Drug poisoning made up the largest proportion of poisoning-related admissions (43.5% followed by pesticide poisoning (37.5%. Among poisoning with pharmaceutical agents, most cases were due to paracetamol (13.7% followed by anti-psychotics and sedatives (5.4%. In pesticide poisonings, the most common classes ingested by the patients were rodenticides and organophosphates. The most common household items ingested by the patients were petroleum products. The average length of hospital stay was 5.5 days. Seven patients (4.2% died, of which 4 were due to organophosphates followed by 2 due to carbamates and one due to rodenticide ingestion. Conclusion: Pharmaceutical and pesticide products were identified as the main cause of poisoning. This finding warrants educational programs for adequate safety measures on storage and use of these substances.

    Hospitalized patients with acute poisoning come from all classes of society. The relationship between living conditions and pattern of poisoning is, however, unclear. The aim of this study was to examine the connection between living conditions in Oslo and the pattern of acute poisonings, measured by incidence, main toxic agents and intention. A one-year multi-centre study with prospective inclusion of all patients ≥ 18 years of age with a registered address in Oslo admitted to an Oslo hospital with acute poisoning from 1 April 2003 through 31 March 2004. The 15 city districts were grouped into three, according to the official living conditions index in Oslo: city district group 1 (best living conditions), city district group 2 (average living conditions) and city district group 3 (most difficult living conditions). Of a total of 947 patients admitted with acute poisoning as their main diagnosis in the study period, 691 were included in the study, 660 of whom had self-inflicted poisoning. In city district group 3, the annual incidence of acute poisonings was 2.14 per 1000 inhabitants, significantly higher than city district group 2, with 1.50 (p < 0.001), and city district group 1, with 1.36 (p < 0.001). Measured as intention assessed by the treating physician, suicidal and drug related poisonings and those induced by a "cry for help" were more common in city district group 3 (0.74, 0.59 and 0.74 per 1000 inhabitants, respectively) than in city district group 2 (0.62, 0.40 and 0.41, respectively) and city district group 1 (0.52, 0.32 and 0.45, respectively). The main toxic agents were predominantly benzodiazepines (20 %), ethanol (18 %) and paracetamol (12 %). There were no statistically significant differences in the distribution of main toxic agents between the city district groups. The findings show a social gradient, with the highest incidence of poisonings in the city district group with the most difficult living conditions.

    Full Text Available In the general structure of occupational diseases, a large proportion belongs to acute poisoning with pesticides (mainly group cases. However, today it is impossible to drop the use of pesticides in agriculture. Their application ensures high biological and economic efficiency of the latter, reduces losses of the yield. The purpose of the work was to predict the possibility of acute toxic effects in agricultural workers when working with combined formulations based on difenoconazole. Materials and methods. To assess the influence on the organism of the workers of the above-mentioned substances and formulations on their basis, the coefficient of inhalation poisoning possibility (CIPP, the coefficient of selective action of the pesticide in inhalation effect (CSAing and the selective action of the pesticide in the dermal effect (CSAderm were calculated. Results. Calculated values of CSAing (103.4-4701.2 and CSAderm (237.4-12345.7 for all investigated active substances were more than 100, this indicates to a rather high selectivity of their action. By the CSAing value formulations Celeste Top, Celeste Trio, Dinali, Cydeli Top belong to pesticides with a relatively low selectivity of action when they are inhaled by workers in the process of crops treating, the remaining formulations have a sufficient selectivity of action in inhalation intake. In addition, it should be noted that in general, for all combined preparations CSA values are significantly lower than for separate active ingredients, in addition to the above assumption, can be explained by the presence of other formulants in the preparation that may have not significant but toxic effect on the body of workers. All investigated substances in the probability of occurrence of acute poisoning with the use of combined preparations on their basis are related to the 4th grade of danger according to State Standards 8.8.1.002-98. There was proved relative safety in case of penetration into the

    Aim: The aim of this work has been to present the frequency, etiology and several other socio-demographic characteristics of acute poisoning in children. The treated patients and methods of work: The treated patients were children of all age groups hospitalized in the Pediatric Clinic of Prishtina during year 2009. The study was done retrospectively. The diagnosis was done on the basis of heteroanamnesis and in several cases on the basis of the anamnesis data of a child, routine laboratory tests and toxicologic analysis. Results: 66 (9.4%) poisoned children were treated in the Intensive Care Unit. The biggest number of patients, 37 (56.06%) of them, were male, and out of that number 36 (54.55%) cases were coming from rural areas. The biggest number of them 49 (74.98%) were over 2-6 years old. The poisoning was mostly caused through the digestive tract (ingestion), it happened with 55 cases (83.33%), 56 cases (84,80%) suffered from severe poisoning, whereas 59 cases (89,50%) suffered from accidental poisoning. Regarding the type of the substances that caused poisoning, the most frequent were drugs in 34 (51.50%) cases and pesticides in 20 (30.30%) cases. Among drugs, the most dominant were those belonging to a group of benzodiazepines (10 cases) and metoclopramide (4 cases). Among pesticides the most dominant one that caused poisoning was malation (5 cases), then paration and cipermetrina appeared in 3 cases each. The biggest number of cases, 64 (96.96%) of them, were treated, whereas 2 cases (3.40%) passed away. Conclusion: The practice proved that that our people are not well informed about the poisoning in general, therefore it is necessary that they be educated by the use of all media, written and electronic, as well as other methods of medical education.

    Pesticide self-poisoning accounts for one-third of suicides worldwide, but few studies have investigated the national epidemiology of pesticide suicide in countries where it is a commonly used method. We investigated trends in pesticide suicide, and factors associated with such trends, in Taiwan, a rapidly developing East Asian country. We conducted an ecological study using graphical approaches and Spearman's correlation coefficients to examine trends in pesticide suicide (1987-2010) in Taiwan in relation to pesticide sales, bans on selected pesticides, the proportion of the workforce involved in agriculture and unemployment. We compared pesticide products banned by the Taiwanese government with products that remained on the market and pesticides that accounted for the most poisoning deaths in Taiwan. Age-standardised rates of pesticide suicide showed a 67% reduction from 7.7 per 100,000 (42% of all suicides) in 1987 to 2.5 per 100,000 (12% of all suicides) in 2010, in contrast to a 69% increase in suicide rates by other methods. Pesticide poisoning was the most commonly used method of suicide in 1987 but had become the third most common method by 2010. The reduction was paralleled by a 66% fall in the workforce involved in agriculture but there was no strong evidence for its association with trends in pesticide sales, bans on selected pesticide products or unemployment. The bans mostly post-dated the decline in pesticide suicides; furthermore, they did not include products (e.g. paraquat) that accounted for most deaths and were mainly restricted to selected high-strength formulated products whilst their equivalent low-strength products were not banned. Access to pesticides, indicated by the size of agricultural workforce, appears to influence trends in pesticide suicide in Taiwan. Targeted bans on pesticides should focus on those products that account for most deaths.

    Full Text Available Abstract Background Mercury poisoning can occur as a result of occupational hazard or suicide attempt. This article presents a 36-year-old case admitted to emergency department (ED due to exposure to metallic mercury. Case Presentatıon A 36-year-old woman presented to the ED with a three-day history of abdominal pain, diarrhea and fever. One week ago her daughter had brought mercury in the liquid form from the school. She had put it on the heating stove. One day later, her 14-month old sister baby got fever and died before admission to the hospital. Her blood pressure was 134/87 mmHg; temperature, 40.2°C; heart rate 105 bpm and regular; respiration, 18 bpm; O2 saturation, 96%. Nothing was remarkable on examination and routine laboratory tests. As serine or urinary mercury levels could not be tested in the city, symptomatic chelation treatment with N-acetyl cysteine (NAC was instituted with regard to presumptive diagnosis and history. At the 7th day of admission she was discharged without any sequelae or complaint. At the discharge day blood was drawn and sent for mercury levels which turned out to be 30 μg/dL (normal range: 0 - 10 μg/dL. Conclusion Public education on poisoning and the potential hazards of mercury are of vital importance for community health.

    Full Text Available Objective: to study the specific features of the diagnosis and treatment of endothoxicosis as a manifestation of postresus-citative disease in acute exogenous poisoning.Subjects and methods. Clinical, laboratory, and statistical methods of the diagnosis of endotoxicosis complicating the course of acute poisoning by narcotics, psychopharmacological agents, and cauterants, as well as complex physicochemical detoxification were applied to 554 patients.Results. The study pathology has been ascertained to have 3 developmental stages — from functional (primary to developed and terminal clinical and laboratory manifestations as multiple organ dysfunctions. The best therapeutic results are achieved by effective therapeutic measures just in early-stage endotoxicosis, by substantially reducing the rates of death and pneumonia and the time of the latter’s resolution. The major contribution to the reduction in the rate of death due acute poisoning is associated with physicochemical detoxification that considerably lessens the influence of the intoxication factors of postresuscitative disease.Conclusion. When diagnosing endotoxicosis in patients with acute endogenous intoxication, it is necessary to keep in mind a whole spectrum of typical changes in endotoxicosis markers and homeostatic parameters: hematologi-cal, blood rheological, lipid peroxidation/antioxidative systems, which should be timely corrected by the basic efferent artificial detoxification techniques (hemosorption, hemodiafiltration, hemofiltration, by compulsorily employing physio-and chemohemotherapy (laser-ultraviolet hemotherapy, sodium hypochlorite infusion.

    Full Text Available Acute pesticide poisoning is a common mode of intentional self harm. Oral ingestion is the usual mode of poisoning. However, inhalation, accidental or occupational transdermal exposure leading to acute or chronic poisoning can be the other route of poisoning. It has been seen that the purpose of poising is suicidal intensity in most of the cases. We report an unusual case where the victim had acute pesticide poisoning through transdermal route that was intended for non suicidal purpose. The patient was managed successfully with immediate decontamination and adequate antidote.

    Full Text Available      Carbon monoxide (CO is a toxic gas produced by the incomplete combustion of carbon-containing compounds. Exposure to high concentrations of CO can be letha and is the most common cause of death from poisoning worldwide. Cardiac manifestations after exposure to CO, including myocardial ischemia, heart failure, and arrhythmias, have been reported. A 28-year-old a patient was admitted to our emergency department with altered consciousness as a consequence of acute domestic exposure to CO from a stove. His carboxyhemoglobin level was 39%. The oxygen treatment was started promptly, and therapeutic red cell exchange was performed. An electrocardiogram revealed supraventricular tachycardia (SVT, and an echocardiographic examination demonstrated normal cardiac functions. To the best of our knowledge, this study is the second to report a case of SVT attack due to acute CO intoxication. This paper discusses the management of this complication in patients poisoned with CO.

Subjects and methods. The results of treatment were analyzed in 32 patients admitted in 2009—2011 for severe acute carbon monoxide poisoning and a Glasgow coma score of 6—8. The patients were divided into 2 groups: 1 patients whose combination therapy involved hyperbaric oxygenation, Succinasol infusions, and L-lysine-aescinate injections; 2 those who received traditional therapy. All the patients underwent complex clinical, laboratory, and neurophysiologic examinations. Results. Just 24 hours after the combination use of Succinasol and L-lysine-aescinate, Group I patients were observed to have substantially reduced lactate, the content of the latter approached the normal value following 48 hours, which was much below the values in the control group. The similar pattern was observed when endogenous intoxication parameters were examined. During the performed therapy, the level of consciousness and that of intellect according to the MMSE and FAB scales were restored more rapidly in the study group patients than in Group 2. Conclusion. The combination use of hyperbaric oxygenation, the succinate-containing solution Succinasol, and the anti-edematous agent L-lysine-aescinate considerably enhances the efficiency of intensive therapy for acute carbon monoxide poisoning. Key words: carbon monoxide, toxic hypoxic encephalopathy, combination therapy, hyperbaric oxygenation, succinic acid, L-lysine-aescinate.

    Full Text Available The aim of this study was to estimate the diagnostic value of renal cortex copper (Cu concentration in clinical cases of acute copper poisoning (ACP. A total of 97 calves that died due to subcutaneous copper administration were compiled in eleven farms. At least, one necropsy was conducted on each farm and samples for complementary analysis were taken. The degree of autolysis in each necropsy was evaluated. The cases appeared on extensive grazing calf breeding and intensive feedlot farms, in calves of 60 to 200 kg body weight. Mortality varied from 0.86 to 6.96 %, on the farms studied. The first succumbed calf was found on the farms between 6 and 72 hours after the susbcutaneous Cu administration. As discrepancies regarding the reference value arose, the local value (19.9 parts per million was used, confirming the diagnosis of acute copper poisoning in 93% of the analyzed kidney samples. These results confirm the value of analysis of the cortical kidney Cu concentration for the diagnosis of acute copper poisoning.

    There is no specific toxicological screening of clinical laboratory parameters in clinical toxicology when it comes to acute exogenous poisoning. To determine routine clinical laboratory parameters and indicators for assessment of vital functions in patients with acute intoxications. One hundred and fifty-three patients were included in the present study. They were hospitalized in the Department of Clinical Toxicology at St. George University Hospital, Plovdiv for cerebral toxicity inducing medication (n = 45), alcohol (n = 40), heroin abuse (n = 33). The controls were 35. The laboratory tests were conducted in compliance with the standards of the clinical laboratory. We used the following statistical analyses: analysis of variance (the ucriterion of normal distribution, the Student's t-test, dispersion analysis based on ANOVA) and non-parametric analysis. Based on the routine hematological parameters with statistically significant changes in three groups of poisoning are: red blood cells, hematocrit, hemoglobin (except alcohol intoxication) and leukocytes. We found statistically significant changes in serum total protein, sodium and bilirubin. The highest statistical significance is the increased activity of AST and ALT. We present a model for selection of clinical laboratory tests for severe acute poisoning with modern equipment under standardized conditions. The results of the study suggest that the clinical laboratory constellation we used can be used as a mandatory element in the diagnosis of moderate and severe intoxication with the mentioned toxic substances.

    Introduction. We investigated a cluster of pesticide poisoning in Orissa. Methods. We searched the village for cases of vomiting and sweating on 2 February 2008. We described the outbreak by time, place, and person. We compared cases with controls. Results. We identified 65 cases (two deaths; attack rate: 12 per 1000; case fatality: 3%). The epidemic curve suggested a point source outbreak, and cases clustered close to a roadside eatery. Consumption of water from a specific source (odds ratio [OR]: 35, confidence interval [CI]: 13 93) and eating in the eatery (OR: 2.3, CI: 1.14.7) was associated with illness. On 31 January 2008, villagers had used pesticides to kill street dogs and had discarded leftovers in the drains. Damaged pipelines located beneath and supplying water may have aspirated the pesticide during the nocturnal negative pressure phase and rinsed it off the next morning in the water supply. Conclusions. Inappropriate use of pesticides contaminated the water supply and caused this outbreak. Education programs and regulations need to be combined to ensure a safer use of pesticides in India.

    Full Text Available Background:Acute poisoning with organophosphorus (OP pesticides is a common method of suicide and entails considerable mortality in Bangladesh. The objective of this study was to evaluate the effects and outcomes of a protocol for treatment of OP poisoning that included titrated incremental atropine as loading dose and slow infusion for maintenance.  Methods:In this prospective descriptive case series, definitive OP poisoned patients were enrolled in an adult medicine unit of Dhaka Medical College Hospital from April 2006 to April 2007. Clinical examinations were done as soon as the patient entered the ward. Patient’s demographics, comorbid conditions and the occurrence of specific clinical outcomes including death, need for assisted ventilation and clinical complications were recorded. The patients were treated according to the protocol. Results: A total of 56 patients were enrolled over the study period. The median age of the study population was 22.5 years. Most patients were men (67.8%. The most common clinical presentation was miosis (58.9%. In total, 11 patients died (19.6%. Intermediate syndrome developed in 12 patients (21.4% and 6 of them died. Assisted ventilation was required in 16 cases (28.5. Patients with diastolic blood pressure ≤ 70 mmHg and/or GCS ≤ 10 were significantly less likely to survive (P = 0.02, 0.006, respectively. Moreover, early respiratory failure (P < 0.001 and the need for assisted ventilation (P < 0.001 were significantly higher among deceased cases. The mortality rate in this study was similar to previous studies. The frequency of atropine toxicity in the present study (1.8% was considerably lower than conventional regimen used in previous studies. Conclusion:Using the new protocol, lower rate of atropine toxicity developed in victims. Hence, the new protocol appears to be safer and its effectiveness should be further evaluated in case control studies in Bangladesh.    How to cite this article: Ahmed AS

    Full Text Available AIM: In this study, it is aimed to explain the causes of the pesticid intoxication occured in the Vali Saim COTUR Regional Boarding Primary Education School in Karacasu district of the province of Kahramanmaras in May, 2008 and what have been done after the intoxication. METHODS: In the study is an investigation of outbreak. In the study used to face-to-face interviews with patients, parents of patients, menagers and teachers of school and the records of the health foundations and school and the laboratory works. RESULTS: Cases of acute pesticide intoxication first began appearing on 5 May 2008. During the course of the pesticide intoxication 51 cases were determined, though there were no fatalities. All cases are students of the Vali Saim COTUR RBPES. It has 1695 students. All cases, 35 (68.6% were females and 16 (31.4% males, and median age 11 (min=8, max=14. Intoxication was highest level as 84.3% in cases at the age of 11. The cause of the intoxication was agriculture medicine (pesticide contamination of the school’s drinking water. CONCLUSION: In order to prevent pesticide poisoning, it is necessary to be very careful with pesticide application especially in rural areas. Substances that are least toxic to human and environment, and are licenced and most effective to pests must be used, sensitive people, especially children, must be kept away. More attempts should be made for raising the awereness of zone managers and farmers in order to prevent intoxications. Even if there is important improvement in intoxication management, the most effective method is prevention of poisoning. [TAF Prev Med Bull 2009; 8(3.000: 199-206

    In patients with acute carbon monoxide (CO) poisoning, we have noted wide clinical variability in both criteria for hyperbaric oxygen (HBO2) treatment as well as HBO2 treatment regimens. Our aim was to survey Midwest hyperbaric centers for insight into specific criteria and protocols for treating acute CO toxicity with HBO2. Hyperbaric centers were identified from the published list of the Undersea and Hyperbaric Medical Society. Ninety-three centers from nine Midwestern states were contacted via telephone. A standard script was used to minimize surveyor bias. Thirty centers that treat CO poisonings were identified. One did not participate in the study. Nineteen reported a specific level of carboxyhemoglobin (COHb) that served as an independent indication for initiation of HBO2 treatment. Four centers used the COHb level as the exclusive indication for HBO2 treatment. Ten centers relied solely on reported symptoms, while the remaining centers used a combination of symptoms plus COHb levels. There were 19 separate treatment protocols. No uniform practice for either the initiation or implementation of HBO2 therapy for CO poisoning exists among U.S. Midwest hyperbaric centers responding to a survey. We see opportunity for specific targeted educational programs as well as further study.

  19. Acute and chronic lead poisoning in cattle

    Three cases of acute plumbism in cows are detailed: one of a six-year-old cow who accidentally ate about 100 gm. of lead (in 1956); the second of a 12-year-old cow who accidentally ate a packet containing about 100 gm. of lead used in painting; and the third of a three-week-old heifer who licked a freshly painted bucket. Route of exposure to lead can be gastrointestinal following deposition of lead fumes (lead oxide, sulfide, and sulfate) on pasturage and in exposed drinking water, or respiratory following the inhalation of such fumes. The presence of CO/sub 2/ in the respiratory tract is thought to provide a favorable situation for the dissolution of lead and the formation of soluble lead complexes. One author has calculated that 12% of respired lead is absorbed into the organism, while only 1-2% of ingested lead is absorbed.

    Cases of people presenting with poisoning are likely to develop acute renal failure (ARF), which may be due to multiple mechanisms/aetiologies. These cases need careful observation and appropriate treatment. To find the risk of ARF among acute poisoning cases, identify the underlying causes and to analyse the outcome. In this prospective study with nested case control, 1,250 cases admitted to the Poison Control, Training and Research Centre of Government General Hospital, Madras Medical College were monitored and evaluated for development of ARF. Patients with history of diabetes/hypertension, known chronic kidney disease, chronic NSAID therapy, those on drugs that increase serum creatinine by inhibiting creatinine secretion and other co-morbid illnesses were excluded. Data were interpreted after subjecting them to bivariate logistic regression and then step wise multivariate analysis. Thirty-two cases developed ARF. Twenty-four were due to snake bite, the rest due to chemical poisons. Chances of developing ARF were greater (6.15%) among the poisoning due to bites and stings than chemical poisoning (0.9%). Five in the former and seven in the latter expired. Among cases bitten by snakes, only 22 (7%) cases bitten by Russell Viper Daboia russelii developed renal failure. Copper sulphate and rat killer poisonings were the commonest causes of chemical induced ARF, dichromate, indigenous medicines and vasmol 33 (paraphenelyne diamine) were the least causes for ARF. None of the patients with organophosphate developed ARF nor did any of the 150 admitted for overdose of medicines developed ARF. The risk of ARF among the cases of poisoning was 2.5%. The outcome of ARF among bites and stings was better than chemical poisoning, and the difference was highly significant (p= 0.005, OR = 0.04-1.0, 95% CI = 0.004-0.38). Early recognition and appropriate measures reduce the occurrence of ARF. © 2011 European Dialysis and Transplant Nurses Association/European Renal Care

    Most patients with acute poisoning are treated as outpatients worldwide. In Oslo, these patients are treated in a physician-led outpatient clinic with limited diagnostic and treatment resources, which reduces both the costs and emergency department overcrowding. We describe the poisoning patterns, treatment, mortality, factors associated with hospitalization and follow-up at this Emergency Medical Agency (EMA, "Oslo Legevakt"), and we evaluate the safety of this current practice. All acute poisonings in adults (> or = 16 years) treated at the EMA during one year (April 2008 to April 2009) were included consecutively in an observational study design. The treating physicians completed a standardized form comprising information needed to address the study's aims. Multivariate logistic regression analysis was used to identify the factors associated with hospitalization. There were 2348 contacts for 1856 individuals; 1157 (62%) were male, and the median age was 34 years. The most frequent main toxic agents were ethanol (43%), opioids (22%) and CO or fire smoke (10%). The physicians classified 73% as accidental overdoses with substances of abuse taken for recreational purposes, 15% as other accidents (self-inflicted or other) and 11% as suicide attempts. Most (91%) patients were treated with observation only. The median observation time until discharge was 3.8 hours. No patient developed sequelae or died at the EMA. Seventeen per cent were hospitalized. Gamma-hydroxybutyric acid, respiratory depression, paracetamol, reduced consciousness and suicidal intention were factors associated with hospitalization. Forty-eight per cent were discharged without referral to follow-up. The one-month mortality was 0.6%. Of the nine deaths, five were by new accidental overdose with substances of abuse. More than twice as many patients were treated at the EMA compared with all hospitals in Oslo. Despite more than a doubling of the annual number of poisoned patients treated at the EMA

    To summarise the clinical features of 18 cases with acute trichloropropane (TCP) poisoning for improving the diagnosis and treatment of the disease. Exposure history, clinical manifestations, laboratorial examinations, poisoning causes and treatment were retrospectively reviewed in 18 cases with acute TCP poisoning. The results of peripheral lymphocyte micronucleus tests were compared with the healthy control group (n = 33). The common clinical symptoms were as following: respiratory symptoms were the earlier one set, such as chest tightness in 13, dry and sore throat in 7, cough and runny nose in 2. Gastrointestinal symptoms were more common, such as abdominal pain in 18, nausea and vomit in 14. Only 1 out of 18 patients was found with liver injury. The major manifestation was the increase in ALT and AST, which was returned to normal after treatment. ALL of the 18 patients were found TCP in their serum which concentration was from 39.0 to 310.0 ng/ml, and the average was (68.9 ± 42.1) ng/ml. The symptoms of toxic peripheral neuropathy were typical in all the patients, such as fatigue and numb limb in 18, burning pain of the distal lower limbs in 14, the symmetrical sock-like sensory dysfunction of pain, touch and vibration of the lower limbs in 13, muscle strength reduced in 7, hyporeflexia knee-jerks in 4, hyporeflexia ankle-jerks in 3. The peripheral nerve conduction velocity (NCV) examinations were as followed: the (sensore-nerve conduction velocity) SCV of peroneus super nerve in 18 and the (motor-nerve conduction velocity) MCV of tibial nerve in 8 was slowed down and the distal latency in 18 was prolonged. Micronucleus were found in all 18 cases. The micronucleus rate was 10.06‰ ± 2.80‰ and 8.24‰ ± 2.67‰ in acute TCP poisoning group and healthy control group, respectively. The difference was significant (P < 0.05). The common clinical manifestations of respiratory exposure of TCP poisoning patients were respiratory symptoms, gastrointestinal

    We reviewed cases of raptor mortality resulting from cholinesterase-inhibiting pesticides. We compiled records from the U.S., U.K. and Canada for the period 1985-95 (520 incidents) and surveyed the relevant literature to identify the main routes of exposure and those products that led to the greatest number of poisoning cases. A high proportion of cases in the U.K. resulted from abusive uses of pesticides (willful poisoning). The proportion was smaller in North America where problems with labeled uses of pesticides were as frequent as abuse cases. Poisoning resulting from labeled use was possible with a large number of granular pesticides and some seed treatments through secondary poisoning or through the ingestion of contaminated invertebrates, notably earthworms. With the more toxic products, residue levels in freshly-sprayed insects were high enough to cause mortality. The use of organophosphorus products as avicides and for the topical treatment of livestock appeared to be common routes of intoxication. The use of insecticides in dormant oils also gave rise to exposure that can be lethal or which can debilitate birds and increase their vulnerability. A few pesticides of high toxicity were responsible for the bulk of poisoning cases. Based on limited information, raptors appeared to be more sensitive than other bird species to organophosphorus and carbamate pesticides. Some of the more significant risk factors that resulted in raptor poisonings were: insectivory and vermivory; opportunistic taking of debilitated prey; scavenging, especially if the gastrointestinal tracts are consumed; presence in agricultural areas; perceived status as pest species; and flocking or other gregarious behavior at some part of their life cycle. Lethal or sublethal poisoning should always be considered in the diagnosis of dead or debilitated raptors even when another diagnosis (e.g., electrocution, car or building strike) is apparent. Many cases of poisoning are not currently

    Although national poison center data show that pesticides were the 8th most commonly reported substance category (3.27%) for children aged ≤5 years in 2014, there is limited information on childhood and adolescent pesticide exposures. This study assessed pesticide-related poison center exposures in children and adolescents aged ≤19 years from 2000-2013 in Texas to characterize the potential burden of pesticides. Pesticide-related poison center exposures among children and adolescents aged ≤19 years reported to Texas poison centers were identified. The distribution of exposures was estimated by gender, age category, medical outcome, management site, exposure route, and pesticide category. From 2000 to 2013, there were 61,147 pesticide-related poison center exposures in children and adolescents aged ≤19 years. The prevalence was highest among males at 864.24 per 100,000 population. The prevalence of unintentional exposures was highest among children aged ≤5 years at 2310.69 per 100,000 population, whereas the prevalence of intentional exposures was highest among adolescents aged 13-19 years at 13.82 per 100,000 population. A majority of medical outcomes reported were classified as having no effect (30.24%) and not followed, but minimal clinical effects possible (42.74%). Of all the exposures, 81.24% were managed on site. However, 57% of intentional exposures were referred to or treated at a health-care facility. The most common routes of exposure were ingestion (80.83%) and dermal (17.21%). The most common pesticide categories included rodenticides (30.02%), pyrethrins/pyrethroids (20.69%), and other and unspecified insecticides (18.14%). The study found differences in the frequency of exposures by intent for sex and age categories, and identified the most common medical outcomes, management site, exposure route, and pesticide category. Through characterizing pesticide-related poison center exposures, future interventions can be designed to address groups

    Cerebral computed tomographic (CT) findings of acute carbon monoxide (Co) poisoning were analized in thirty-six cases treated with hyperbraric oxygen therapy and their relationship with prognosis was evaluated. The cases were classified into there groups, early stage, interval form, and non-interval form groups. In all groups, the initial abnormality was low density areas presumably due to edema, demyelination and/or softening. It was seen in the globus pallidus and/or white matter. Following these initial changes, cerebral hemorrhage, ventricular dilatation, and cerebral atrophy developed in a few cases. The frequency of abnormal CT findings was higher in the interval form group (85 %) or non-interval group (83 %) than the early stage group (41 %). The prognosis was good in most cases with normal CT findings. The possibility of recovery diminished in the patients with abnormal CT findings. The prognosis was particularly poor in cases showing abnormality both in globus pallidus and white matter. We conclude that CT is useful not only for detecting the pathologic change but also for predicting the prognosis of the patient with acute Co poisoning. (author)

    Prevention and control of damage to health, crops, and property by insects, fungi, and noxious weeds are the major goals of pesticide applications. As with use of any biologically active agent, pesticides have unwanted side-effects. In this review, we will examine the thesis that adverse pesticide effects are more likely to occur in children who are at special developmental and behavioral risk. Children's exposures to pesticides in the rural and urban settings and differences in their exposure patterns are discussed. The relative frequency of pesticide poisoning in children is examined. In this connection, most reported acute pesticide poisonings occur in children younger than age 5. The possible epidemiological relationships between parental pesticide use or exposure and the risk of adverse reproductive outcomes and childhood cancer are discussed. The level of consensus among these studies is examined. Current concerns regarding neurobehavioral toxicity and endocrine disruption in juxtaposition to the relative paucity of toxicant mechanism-based studies of children are explored

    To analyze severe acute occupational poisoning accidents reported in China between 1989 and 2003, and to study the characteristics of severe acute occupational poisoning accidents and provide scientific evidences for prevention and control strategies. The data from the national occupational poisoning case reporting system were analyzed with descriptive methods. (1) There were 506 acute severe occupational poisoning accidents for 15 years with 4 657 workers poisoned. The total poisoning rate was 54.8%, and the total mortality was 16.5%. The average poisoning age was (31.9 +/- 9.8) years old and the average death age was (33.7 +/- 10.3) years old. The poisoning accidents occurred more in men than in women. (2) There were more than 112 chemicals which caused these poisoning accidents. Most of the accidents caused by hydrogen sulfide, carbon monoxide, benzene and homologs, metal and metalloid and carbon dioxide, and the types of chemicals varied in different types of industries. (3) The accidents mainly occurred in chemical industry, manufacture, water disposal industry, mining and construction industry, and the risk was higher in some jobs than others, such as cleanout, machine maintenance and repair, production, mine and digging. The accidents occurred more frequently from April to August each year. (1) The control over the severe acute occupational poisoning is urgent. (2) The trend of the characteristics of severe acute occupational poisoning accidents is centralized in the high risk industries, poisons and jobs. (3) The characteristics of the accidents varied in different types of industries. (4) It is the key point to strengthen the supervision on poisoning.

    Full Text Available Introduction. Caffeine is indicated in the treatment of migraine headaches, as well as neonatal apnea and bradycardia syndrome. In mild poisoning, the most prevalent symptoms are nausea, vomiting, diarrhea, tremor, anxiety and headache. In more severe cases, symptoms consist of heart rythym abnormalities, myocardial infarction and seizures. Due to its common lipolytic effect, caffeine is used in mesotherapy, usually in combination with drugs of similar effect. We presented a patient with acute iatrogenic caffeine poisoning. Case report. A 51-year-old woman, with preexisting hypertension and hypertensive cardiomyopathy was subjected to cosmetic treatment in order to remove fat by intradermal caffeine injections. During the treatment the patient felt sickness, an urge to vomit, and a pronounced deterioration of general condition. Upon examination, the patient exhibited somnolence, hypotension and nonsustained ventricular tachycardia, which was sufficient enough evidence for further hospitalization. On admission to the intensive care unit the patient was anxious with increased heart rate, normotensive, with cold, damp skin, and visible traces of injection sites with surrounding hematomas on the anterior abdominal wall. Paroxysmal supraventricular tachycardia (PSVT on electrocardiographic monitoring was found. The laboratory analysis determined a lowered potassium level of 2.1 mmol/L (normal range 3,5 - 5.2 mmol/L, and a toxicological analysis (liquid chromatography with ultraviolet detection proved a toxic concentration of caffeine in plasma - 85.03 mg/L (toxic concentration over 25 mg/L.

    Caffeine is indicated in the treatment of migraine headaches, as well as neonatal apnea and bradycardia syndrome. In mild poisoning, the most prevalent symptoms are nausea, vomiting, diarrhea, tremor, anxiety and headache. In more severe cases, symptoms consist of heart rythym abnormalities, myocardial infarction and seizures. Due to its common lipolytic effect, caffeine is used in mesotherapy, usually in combination with drugs of similar effect. We presented a patient with acute iatrogenic caffeine poisoning. A 51-year-old woman, with preexisting hypertension and hypertensive cardiomyopathy was subjected to cosmetic treatment in order to remove fat by intradermal caffeine injections. During the treatment the patient felt sickness, an urge to vomit, and a pronounced deterioration of general condition. Upon examination, the patient exhibited somnolence, hypotension and nonsustained ventricular tachycardia, which was sufficient enough evidence for further hospitalization. On admission to the intensive care unit the patient was anxious with increased heart rate, normotensive, with cold, damp skin, and visible traces of injection sites with surrounding hematomas on the anterior abdominal wall. Paroxysmal supraventricular tachycardia (PSVT) on electrocardiographic monitoring was found. The laboratory analysis determined a lowered potassium level of 2.1 mmol/L (normal range 3,5 - 5.2 mmol/L), and a toxicological analysis (liquid chromatography with ultraviolet detection) proved a toxic concentration of caffeine in plasma - 85.03 mg/L (toxic concentration over 25 mg/L). On application of intensive therapy, antiarrhythmics, and substitution of potassium, as well as both symptomatic and supportive therapy, there was a significant recovery. The patient was discharged without any sequele within four days. A presented rare iatrogenic acute caffeine poisoning occured due to massive absorption of caffeine from the subcutaneous adipose tissue into the circulation when injected

  15. Pesticide Exposure in Children

    2018-01-01

    Pesticides are a collective term for a wide array of chemicals intended to kill unwanted insects, plants, molds, and rodents. Food, water, and treatment in the home, yard, and school are all potential sources of children’s exposure. Exposures to pesticides may be overt or subacute, and effects range from acute to chronic toxicity. In 2008, pesticides were the ninth most common substance reported to poison control centers, and approximately 45% of all reports of pesticide poisoning were for children. Organophosphate and carbamate poisoning are perhaps the most widely known acute poisoning syndromes, can be diagnosed by depressed red blood cell cholinesterase levels, and have available antidotal therapy. However, numerous other pesticides that may cause acute toxicity, such as pyrethroid and neonicotinoid insecticides, herbicides, fungicides, and rodenticides, also have specific toxic effects; recognition of these effects may help identify acute exposures. Evidence is increasingly emerging about chronic health implications from both acute and chronic exposure. A growing body of epidemiological evidence demonstrates associations between parental use of pesticides, particularly insecticides, with acute lymphocytic leukemia and brain tumors. Prenatal, household, and occupational exposures (maternal and paternal) appear to be the largest risks. Prospective cohort studies link early-life exposure to organophosphates and organochlorine pesticides (primarily DDT) with adverse effects on neurodevelopment and behavior. Among the findings associated with increased pesticide levels are poorer mental development by using the Bayley index and increased scores on measures assessing pervasive developmental disorder, inattention, and attention-deficit/hyperactivity disorder. Related animal toxicology studies provide supportive biological plausibility for these findings. Additional data suggest that there may also be an association between parental pesticide use and adverse birth

    Direct lethal and sublethal effects of pesticides on farmland birds' populations are recurring questions and largely debated. In this context, we conducted an innovative study combining radiotelemetry, farmer surveys, residue analyses on carcasses and modelling to assess the unintentional effects of pesticides on terrestrial birds. We chose the grey partridge Perdix perdix as a case study because this typical bird of European cereal ecosystems is highly exposed to pesticides. In this paper we focused on acute and short-term impacts of pesticides on adult mortality during spring and summer in a one-substance approach (multiple exposure were not studied here) but for a large variety of active substances (a.s.) actually used in cultivated farmland of Northern France. The fate and the location of 529 partridges were monitored twice a day from early March to late August 2010 and 2011 on 12 sites (14,500 ha). Their daily potential exposure to 183 a.s. was determined by overlapping birds' habitat use and daily pesticide application data. Based on this procedure, we calculated mortality rates within 10 days following a potential exposure for 157 different a.s.. 5 a.s. were associated with a "10-day mortality rate" higher than 10% but a single one (thiacloprid) is reported to be highly toxic to birds. We recorded 261 mortalities among which 94 carcasses were in suitable condition for residue analyses. We detected at least one a.s in 39.4% of carcasses. However, only 2 mortality cases were attributed to poisoning (carbofuran). Furthermore, modelling results showed that these lethal pesticide-related poisonings decreased the population growth rate by less than 1%. In conclusion, we did not point out important direct acute and short-term effects of pesticides currently used by farmers during the breeding season on the grey partridge. This is discussed with regards to the complexity of potential effects in operational conditions. Copyright © 2015 Elsevier Inc. All rights

    The brain CT findings in 19 patients with acute carbon monoxide poisoning was analysed and the emphasis was placed on the relationship between CT findings and prognosis. Five had a normal manifestation in CT ; eight had the findings of ovoid or patchy low density area in globus pallidus, bilateral or unlateral, during the second day to fifth week after poisoning, and the low density areas were decreasing and blurring in edge in follow up and at last disappeared during 3 - 14 weeks in three cases of them ; nine showed the appearance of diffuse low density of white matter and of globus pallidus in some of them ; two had an appearance of brain atrophy. The pathology of CT findings mentioned above may be brain edema, necrosis, malacia and degeneration in gray matter and globus pallidus. The result suggested the cases with normal CT manifestation, cerebral edema and decreasing and disappearing low density area had a good prognosis, in contrary, the cases with persistant low density in globus pallidus had a poorer prognosis.

    Acute carbon monoxide (CO) poisoning is the most common cause of death from poisoning all over the world and may result in neuropathologic and neurophysiologic changes. Acute brain damage and delayed encephalopathy are the most serious complication, yet their pathogenesis is poorly understood. The present study aimed to evaluate the neuroprotective effects of Edaravone against apoptosis and oxidative stress after acute CO poisoning. The rat model of CO poisoning was established in a hyperbaric oxygen chamber by exposed to CO. Ultrastructure changes were observed by transmission electron microscopy (TEM). TUNEL stain was used to assess apoptosis. Immunohistochemistry and immunofluorescence double stain were used to evaluate the expression levels of heme oxygenase-1 (HO-1) and nuclear factor erythroid 2-related factor 2 (Nrf-2) protein and their relationship. By dynamically monitored the carboxyhemoglobin (HbCO) level in blood, we successfully established rat model of severe CO poisoning. Ultrastructure changes, including chromatin condensation, cytoplasm dissolution, vacuoles formation, nucleus membrane and cell organelles decomposition, could be observed after CO poisoning. Edaravone could improve the ultrastructure damage. CO poisoning could induce apoptosis. Apoptotic cells were widely distributed in cortex, striatum and hippocampus. Edaravone treatment attenuated neuronal apoptosis as compared with the poisoning group (P Edaravone, the expression of HO-1 and Nrf-2 significantly increased (P Edaravone may inhibit apoptosis, activate the Keapl-Nrf/ARE pathway, and thus improve the ultrastructure damage and neurophysiologic changes following acute CO poisoning. © 2014 Wiley Periodicals, Inc.

    Full Text Available Introduction: Poisoning with various substances is a major public health problem and a reason for significant morbidity and mortality throughout the globe. It is one of the most common presentation in an emergency department. This study was conducted to determine the sociodemographic, poisoning types, and mode of poisoning in cases attending a tertiary hospital of Western Nepal. Methods: A retrospective observational study of two years was conducted from July 2014 to June 2016. Demography details, name of poisonous substance, and reasons for poisoning were reviewed and analyzed using descriptive statistics. Results: A total of 65 cases of poisoning were recorded. The occurrence was more common in female (n=44, 67.7% than in male (n=21, 32.3% with a F:M ratio of 2.1:1.  Poisoning  was most  common in the age group of 11-20 years (32.3%. Most of the cases were students (37% followed by farmers (26%. The most commonly abused poisoning substance were organophosphorous compounds, zinc-phosphate,  and  kerosene in adults, adolescents, and children respectively. Oral route was the most common (99% route of administration. Suicidal attempt, as a mode of poisoning, accounted for 70.8% of total poisoning cases. Conclusion: Female and young people are at greater risk of acute poisoning. Insecticide was the most common agent and self administer poisoning was the most common mode of poisoning. The occurrence of poisoning and its morbidity and mortality can be reduced by developing and implementation of effective prevention strategies like restricting easy poison sales, establishing drug and poison information centers,  and community awareness programs.

    A case of favourable outcome of the treatment of extremely severe acute poisoning after prolonged exposure to lethal doses of methanol is reported. The complex treatment included urgent and effective elimination of the poison (multiple gastric lavage, hemodialysis), antidote therapy (administration of ethanol), correction of decompensated metabolic acidosis (alkali therapy and infusion therapy with reamberin). These measures had beneficial effect on the clinical course of poisoning and ensured its favourable outcome.

    Organophosphates (OP) account for the majority of pesticide-related unintentional or intentional poisonings in lower- and middle-income countries. The therapeutic role of atropine is well-established for patients with acute OP poisoning. The benefit of adding 2-pyridine aldoxime methyl chloride (2-PAM), however, is controversial. We performed a systematic review and meta-analysis of available randomized controlled trials (RCT) to compare 2-PAM plus atropine in comparison to atropine alone for acute OP poisoning. We searched PubMed, EMBASE, and SCOPUS up to March 2017. The Cochrane review handbook was used to assess the risk of bias. Data were abstracted and risk ratios (RR) were calculated for mortality, rate of intubation, duration of intubation, intermediate syndrome, and complications such as hospital-acquired infections, dysrhythmias, and pulmonary edema. We found five studies comprising 586 patients with varying risks of bias. The risk of death (RR = 1.5, 95% CI 0.9-2.5); intubation (RR = 1.3, 95% CI 1.0-1.6); intermediate syndrome (RR = 1.6, 95% CI 1.0-2.6); complications (RR = 1.2, 95% CI 0.8-1.8); and the duration of intubation (mean difference 0.0, 95% CI - 1.6-1.6) were not significantly different between the atropine plus 2-PAM and atropine alone. Based on our meta-analysis of the available RCTs, 2-PAM was not shown to improve outcomes in patients with acute OP poisoning.

    Pesticide self-poisoning is one of the most frequently used methods of suicide worldwide, killing over 300,000 people annually. Around 15-20% of pesticide self-poisonings occur soon after the person has bought the pesticide from a shop. We aim to determine the characteristics of individuals who purchase pesticides directly from shops and how they differ from individuals who access pesticides from other sources such as home, home garden or farmland. This information will help inform possible vendor/shop-based intervention strategies aimed at reducing access to pesticides used for self-harm. This study will investigate risk factors associated with purchasing pesticides for acts of self-poisoning from pesticide shops, including cases identified over a 9-month period using a population-based case-control group approach. Four interviewer-administered data collection tools will be used for this study: a semistructured questionnaire, Beck Suicidal Intent Scale (SIS), Clinical Interview Schedule-Sinhalese version (CIS-Sn) and Alcohol Use Disorders Identification Test (AUDIT). Each case (expected n=33) will be compared with two groups of individuals: (1) those who have self-poisoned using pesticides from the home, home garden or farmland and (2) those who bought pesticides from the same shops as the above cases, but not did not self-poison. Logistic regression models will be used to identify risk factors of purchasing pesticides for self-poisoning from shops. The study has received ethical approval from the Ethical Review Committee of the Faculty of Medicine and Allied Sciences, Rajarata University of Sri Lanka. A sensitive data collection technique will be used and ethical issues will be considered throughout the study. Results will be disseminated in scientific peer-reviewed articles.

    Full Text Available In India, acute aluminium phosphide poisoning (AAlPP is a serious health care problem. This study aimed to determine the characteristics of AAlPP and the predictors of mortality at the time of patients′ admission. We studied consecutive admissions of patients with AAlPP admitted to the intensive care unit (ICU between November 2004 and October 2006. We noted 38 parameters at admission to the hospital and the ICU and compared survivor and non-survivor groups. A total of 27 patients were enrolled comprising5 females and 22 males and the mean ingested dose of poison was 0.75 ± 0.745 grams. Hypotension was noted in 24 patients (89% at admission and electrocardiogram abnormalities were noted in 13 patients (48.1%. The mean pH on admission was 7.20 ± 0.14 and the mean bicarbonate concentration was 12.32 ± 5.45 mmol/ L. The mortality from AAlPP was 59.3%. We found the following factors to be associated with an increased risk of mortality: a serum creatinine concentration of more than 1.0 mg % (P = 0.01, pH value less than 7.2 (P = 0.014, serum bicarbonate value less than 15 mmol/L (P = 0.048, need for mechanical ventilation (P = 0.045, need for vasoactive drugs like dobutamine (P = 0.027 and nor adrenaline (P = 0.048 and a low APACHE II score at admission (P = 0.019. AAlPP causes high mortality primarily due to early haemodynamic failure and multi-organ dysfunction

    2012-01-01

    Full Text Available Background/Aim. Saliva is a body fluid which, like serum, can be used for determination of concentrations of certain drugs, both in pharmacotherapy as well as in acute poisonings. The aim of this study was to determine carbamazepine concentrations in both saliva and serum in acute poisoning in order to show if there is a correlation between the obtained values, as well as to monitor toxicokinetics of carbamazepine in body fluides. Methods. Saliva and serum samples were obtained from 26 patients treated with carbamazepine and 20 patients acutely poisoned by the drug immediately after their admission in the Emergency Toxicology Unit. Determination of salivary and serum carbamazepine concentrations was performed by the validated high pressure liquid chromatographyultraviolet (HPLC-UV method. Results. A significant correlation of salivary and serum carbamazepine concentrations in both therapeutic application and acute poisoning (r = 0.9481 and 0.9117, respectively was confirmed. In acute poisonings the mean ratio between salivary and serum concentrations of carbamazepine (0.43 was similar to the mean ratio after its administration in therapeutic doses (0.39, but there were high inter-individual variations in carbamazepine concentrations in the acutely poisoned patients, as a consequence of different ingested doses of the drug. In acute poisoning the halftime of carbamazepine in saliva and serum was 12.57 h and 6.76 h, respectively. Conclusion. Our results suggest a possible use of saliva as an alternative biological material for determination of carbamazepine concentrations in therapeutic application and acute poisoning as well, and a possible extrapolation of the results obtained in saliva to serum concentrations of carbamazepine.

    Objective: To assess the degree of poisoning in farmers using the erythrocyte acetylcholinesterase (AChE) test before and after the exposure to pesticides in townships in central Benin (Glazoué and Savè) and to identify the associated risk factors. Methods: Using a cross-sectional study design, we recruited 264 farm pesticide sprayers, who have been working for at least 5 years. They completed a questionnaire and underwent the AChE test using the Test-mate Model 400 device (EQM Research Inc.) with a photometric sensor, based on the works of Ellman. Results: Organophosphate/pyrethroids were the most common pesticides used by at least 72.96% of the farmworkers. We observed an inhibition of AChE between pre-exposure and post-exposure (P = .002) for 60.61% of the farmworkers. Among them, 11.88% displayed more than 20% AChE inhibition. Conclusions: Pesticide poisoning is a reality, and AChE monitoring is urgently needed for farmworker surveillance. PMID:28469452

    Full Text Available Carbon monoxide poisoning (COP is one of the most common causes of mortality and morbidity due to poisoning in all over the world. Although the incidence of COP has not been known exactly in the childhood, almost one-third of CO exposures occurred in children. The data regarding COP in children are inconclusive. Children may be more vulnerable to CO exposure than adults as a result of their high respiration and metabolic rates, high oxygen metabolism, and immature central nervous system. Recent researches proposed new theories about neurological effects of CO toxicity. The clinical presentations associated acute COP may be various and nonspecific. Unrecognized CO exposure may lead to significant morbidity and mortality. CO exposed children often become symptomatic earlier, and recover more rapidly, than similarly CO exposed adults. Mild clinical signs and symptoms associated with COP are headache, dizziness, weakness, lethargy, and myalgia; however, severe signs and symptoms such as blurred vision, syncope, convulsion, coma, cardiopulmonary arrest and death can also accompany with COP. Neurologic manifestations can include altered mental status at different degrees, neck stiffness, tremor, ataxia, and positive Babinski's sign. Delayed neurologic sequels (DNS of COP might be seen in children like adults. DNS symptoms and signs in children include memory problems, mental retardation, mutism, fecal and urinary incontinence, motor deficits, facial palsy, psychosis, chronic headache, seizures, and epilepsy. After CO exposure children must be cared to detect and treat DNS. Although hyperbaric oxygen therapy (HBOT is reported to prevent development of DNS, its indications, application duration and procedures are controversial in both of the children and adults. Although their predictive values are limited, exposing to CO more than eight hours and suffering from CO-induced coma, cardiac arrest, lactic acidosis, high COHb levels, and pathologic findings

  16. Successful Treatment of Acute Lethal Dose of Acrylamide Poisoning

    Directory of Open Access Journals (Sweden)

    Ali Banagozar Mohammadi

    2015-03-01

    Full Text Available Background: Acrylamide (C3H5NO is a vinyl monomer. This water-soluble crystalline solid is a colorless, odorless agent which is used in scientific laboratories and some industries. Acrylamide has cellular oxidative effects. Acute or chronic poisoning with this agent happens as a result of skin, respiratory, or oral contacts. Clinical manifestations depend on the dose, duration, and frequency of contact. Management of these patients consists of conservative and palliative therapies to reduce the oxidative effects. Case: The case was a 29-year-old girl with a Master of Sciences degree in genetics who worked in a university research center with previous history of depression. She had ingested 100cc of 30% Acrylamide solution for intentional suicide attempt. The patient was successfully managed using N-acetyl cysteine, vitamin C, and melatonin. Conclusion: Early diagnosis and appropriate treatment with recommended agents together with supportive therapies can save the life of patients exposed to potentially lethal doses of acrylamide, although intentional or accidental.

    Full Text Available Acute toxicity is a frequent but avoidable cause of morbidity and mortality in children especially in developing countries, including India. Present study assesses their pattern with relation to different age groupings. This retrospective study was conducted among all hospitalised paediatric victims of acute accidental poisoning at the King George Medical University; Lucknow during 2010 -11. Their history, baseline characteristics, clinical course and outcome was studied. Most children were male of less than three years with 4% overall mortality. Kerosene oil was implicated in most cases. Childhood poisoning is commonest during 1-3 years with a male preponderance. Household poisons; especially kerosene oil was responsible for most cases which was consumed accidentally. Parents must be educated and warned to keep these toxic ingredients safely in suitable containers and out of reach of their beloved children.

    Full Text Available Carbon monoxide (CO poisoning causes the major injury and death due to poisoning worldwide. The most severe damage via CO poisoning is brain injury and mortality. Delayed encephalopathy after acute CO poisoning (DEACMP occurs in forty percent of the survivors of acute CO exposure. But the pathological cause for DEACMP is not well understood. And the corresponding therapy is not well developed. In order to investigate the effects of salvianolic acid (SA on brain injury caused by CO exposure from the view point of hemorheology, we employed a rat model and studied the dynamic of blood changes in the hemorheological and coagulative properties over acute CO exposure. Compared with the groups of CO and 20% mannitol + CO treatments, the severe hippocampal injury caused by acute CO exposure was prevented by SA treatment. These protective effects were associated with the retaining level of hematocrit (Hct, plasma viscosity, fibrinogen, whole blood viscosities and malondialdehyde (MDA levels in red blood cells (RBCs. These results indicated that SA treatment could significantly improve the deformation of erythrocytes and prevent the damage caused by CO poisoning. Meanwhile, hemorheological indexes are good indicators for monitoring the pathological dynamic after acute CO poisoning.

    This paper presents a simple, rapid, reliable, and validated method suited for forensic examination of gasoline in biological samples. The proposed methodology has been applied to the investigation of four fatal cases due to gasoline poisoning that occurred in Spain in 2003 and 2004. Case histories and pathological and toxicological findings are described in order to illustrate the danger of gasoline exposure under several circumstances. Gasoline's tissular distribution, its quantitative toxicological significance, and the possible mechanisms leading to death are also discussed. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography (GC) with flame-ionization detection, and confirmation was performed using GC-mass spectrometry in total ion chromatogram mode. m,p-Xylene peak was selected to estimate gasoline in all biological samples. Gasoline analytical methodology was validated at five concentration levels from 1 to 100 mg/L. The method provided extraction recoveries between 77.6% and 98.3%. The limit of detection was 0.3 mg/L, and the limit of quantitation was 1.0 mg/L. The linearity of the blood calibration curves was excellent with r2 values of > 0.997. Intraday and interday precisions had a coefficient of variation inhalation of gasoline vapor inside a small enclosed space. Case 3 is a death by recreational gasoline inhalation in a male adolescent. Heart blood concentrations were 28.4, 18.0, and 38.3 mg/L, respectively; liver concentrations were 41.4, 52.9, and 124.2 mg/kg, respectively; and lung concentrations were 5.6, 8.4, and 39.3 mg/kg, respectively. Case 4 was an accidental death due to gasoline ingestion of a woman with senile dementia. Peripheral blood concentration was 122.4 mg/L, the highest in our experience. Because pathological findings were consistent with other reports of gasoline intoxication and constituents of gasoline were found in the body, cause of death was attributed to acute gasoline

    In 47 patients treated at the Toxicological Clinic in Krakow for coal-stove-gas poisoning, the aspartate aminotransferase, lactate dehydrogenase, LDH/sub 1/ isoenzyme activities, and the lactate level were studied. Findings were compared with those of earlier investigations carried out on a group of patients poisoned by lighting gas; qualitatively changes in both groups were similar. The biochemical parameters studied aided in quantitative evaluation of the patients' condition: a threefold increase in lactate level on admission to the hospital and a likewise threefold increase in aspartate aminotransferase activity after 24 hrs of treatment are indications of severe poisoning.

    Datura Stramonium (DS) is a common weed along roadsides, in cornfields and pastures and in waste areas. It belongs to the family Solanaceae and its toxic components are tropane belladonna alkaloids. It has been used voluntarily by teenagers for its hallucinogenic effect. The plant is named in Iran as Tatoore. Symptoms and signs of acute D. Stramonium poisoning usually are similar to anticholinergic syndrome. This study is done in order to clarify the status of this poisoning in our region. This study is a case series on all patients admitted to Imam Reza Hospital, Mashhad, Iran, with acute D. Stramonium poisoning between 2008 and 2011. We observed their symptoms, signs, routine laboratory test results and treatment used to control their symptoms. There were 19 patients included in our study. Children were poisoned more commonly than teenagers and poisoning in adults was rare. All of the children ingested the plant accidentally. The most presenting symptom was irritability and the most common sign was sinus tachycardia. There was not any presentation of seizure or coma. Most of the symptoms were controlled by parenteral benzodiazepines and there were no need to use of cholinergic agents such as physostigmine. Our study showed most of D. Stramonium poisoned population in our region are children. We suggest decreasing accessibility to the plant in order to decrease the incidence of its poisoning.

    Carbon monoxide poisoning, a public health problem of considerable significance, is a relatively frequent event today, resulting in thousands of hospitalizations annually. A 70-year-old lady was seen in the emergency department with a provisional diagnosis of carbon monoxide poisoning. The previous night, she slept in a tightly closed room heated with coal ember. She was found unconscious in the morning with poor ventilation. She had a rare presentation of popliteal vein thrombosis, pulmonary emboli, and possible tissue necrosis with carbon monoxide poisoning. Oxygen treatment with low-molecular-weight heparin (nadroparine) and warfarin therapy resulted in an improvement in both popliteal and pulmonary circulations. In conclusion, the presence of pulmonary emboli should be sought in patients with carbon monoxide poisoning.

    Aquatic ecosystems face variable exposure to pesticides, especially during floodings which are associated with short bursts of high contaminant concentrations that influence biological systems. A study was undertaken to highlight the impact of the herbicide diuron applied in mixture with the fungicide tebuconazole on natural periphyton during flooding events. Periphyton were grown in two series of two lotic outdoor mesocosms: one series was non-contaminated while the other was exposed to chronic contamination. After 4 weeks, one channel of each series was exposed to three successive pulses, with each pulse followed by one week of recovery. Impacts on periphyton were assessed by using Denaturing Gel Gradient Electrophoresis to characterize eukaryotic community structure. At a functional scale, photosynthetic efficiency was quantified during each pulse, and the induced tolerance to diuron was estimated by performing short-term inhibition tests based on photosynthetic efficiency. Moreover, pesticide concentrations in the water column and periphyton matrix were measured. Diuron was adsorbed in the periphyton during each pulse and desorbed 13 h after pulse end. The different pulses affected the eukaryotic community structures of the control biofilms, but not of the chronically exposed ones. During the first pulse, photosynthetic efficiency was correlated with pesticide concentration in the water phase, and there was no difference between periphyton from chronically contaminated channels and control channels. However, during the second and third pulses, the photosynthetic efficiency of periphyton chronically exposed to pesticides appeared to be less impacted by the acute pulsed exposure of pesticide. These changes were consistent with the acquisition of induced tolerance to diuron since only after the third pulse that periphyton from chronic channel became tolerant to diuron. Our experimental study indicates that the effects of pulsed acute exposures to pesticides on

    Full Text Available Purpose: Poisoning with drugs occupies a leading position among the causes of acute intoxications. Etiological distribution of medicated poisoning in different countries, even if they are adjacent, is different. In the most studies it was reported that the highest incidence of poisoning is with benzodiazepines or other psychoactive drugs. A retrospective analysis of acute poisoning with benzodiazepines and other hypnotic drugs in the Varna region for 25 years period – from 1991 to 2015 was carried out. Material and Methods: The number of patients who received hospital treatment after poisoning with benzodiazepines is 1741, and those with other hypnotics is 293, representing respectively 26.37% and 4.44% of all drug intoxications. Results: The share of poisoning with benzodiazepines and hypnotics compared to all acute intoxications is 11.66%. They are more common in women – 1566 (77%. Men are 468 (23%, the ratio of men to women was 3.34:1. The largest number of intoxications is in the age group up to 24 years - 1123 (55.2%, and only 4.1% of patients over 60 years. Intentional suicide attempts are 1896 (93.2%. Death is registered in 8 (0.4% patients.

    Full Text Available Abstract Background: poisoning is one of the most common medical emergencies. Every year many people refer to emergency wards due to poisoning and some of them are treated and some die because of severe complications. Most patients who refer to emergency wards are those who commit intentionally to suicide. This study is conducted to determine the prevalence of poisoning with pesticide (organophosphate and organochlorine in persons referred to Shohada Ashaier hospital of Khorramabad in the first six months in 2006. Metrials and methods: Required information of poisoned people with poisoning pesticide (organophosphate and organochlorine were collected using questionnaires which were distributed among the subjects. Results: In this study 153 patients including 118 patients who poisoned with organophophate and 35 patents with organochlorine were studied. Most of the patients (34.6% aged between 21-71 years including 57.5% female and 42.5% male and their education was about under secondary school, 91.5% of them attempted to suicided. The total mortality rate was 12 that 7 of them died by toxifications with organochlorine and 5 cases by organophosphate, which in turn was due to their respiratory complications like ARDS and aspiration pneumonia. Conclusion: findings indicate that due to high prevalence and mortality of poisoning with pesticides, this problem should be taken into consideration.

    Full Text Available Objective: to examine the capacities of pharmacological correction of impairments in oxygen-transporting systems and metabolic processes with perfluorane and cytoflavin in critically ill patients with acute intoxication with neurotropic poisons.Subjects and methods. Metabolic sequels of severe hypoxia, free radical processes, and endogenous intoxications were studied in 62 patients with the severest acute intoxication with neurotropic poisons.Results. The studies have established that hypoxia and metabolic changes lead to the development of endotoxicosis. Intensifying endotoxicosis in turn enhances hypoxic lesion. Thus, the major task of intensive care is to restore oxygen delivery and to diminish metabolic disturbances and endotoxicosis. Ways of correcting hypoxia and metabolic disturbances are considered in the severe forms of acute poisoning

    Full Text Available Background: Poisoning is one of the important reasons for children’s admission to hospital. Knowledge of epidemiology of poisoning in each region plays an important role in planning prevention, care, and treatment of patients. This study was conducted to determine the characteristics of acute poisoning epidemiology in children attending pediatric wards of Amirkabir Hospital in Arak in a five-year period (March 2008 to March 2012. Methods: This descriptive cross-sectional study was conducted on 224 children admitted for poisoning. Data were retrospectively collected from patients’ files and analyzed using SPSS 16 software. Results: Of the total population, 54.9% were boys and the rest were girls. Mean age of children was 3.54±2.99 years, and the most common age range was 1-3 years (50.9%. The highest rate of children’s admission due to poisoning was in the winter (30.8%. The most common causes of poisoning included drugs (65.2%, kerosene (7.1%, and food poisoning (5.4%. The most common poisoning drugs, included benzodiazepines (21.9%, gastrointestinal drugs (19.9%, opioid analgesics (15.1%. The most prevalent drugs were methadone, metoclopramide, and clonazepam. At admission, the most common presenting symptoms were neurological (51.3%, and gastrointestinal symptoms (38.4%. Conclusion: High prevalence of poisoning with groups of drugs mentioned could indicate community-wide excessive use of these drugs, as well as negligence of families in keeping them out of children’s reach. Therefore, raising knowledge and awareness about variety of poisoning and how to prevent them, through holding workshops, national media, schools, and health centers can be a valuable step toward upkeep of children’s health.

    Methanol poisoning is an uncommon but potent central nervous system toxin. We describe here the CT and MR findings in nine patients following an outbreak of methanol poisoning. Five patients with a typical clinical presentation and elevated anion and osmolar gaps underwent conventional brain MRI with a 1.5-T Gyroscan Interna scanner. In addition nonenhanced CT was performed in another three patients with more severe toxicity. Bilateral hemorrhagic or nonhemorrhagic necrosis of the putamina, diffuse white matter necrosis, and subarachnoid hemorrhage were among the radiological findings. Various patterns of enhancement of basal ganglial lesions were found including no enhancement, strong enhancement and rim enhancement. A good knowledge of the radiological findings in methanol poisoning seems to be necessary for radiologists. The present study is unique in that it enables us to include in a single report most of the radiological findings that have been reported previously. (orig.)

    Mushroom exposures are increasing worldwide. The incidence and fatality of mushroom poisoning are reported to be increasing. Several new syndromes in mushroom poisoning have been described. Rhabdomyolytic mushroom poisoning is one of new syndromes. Russula subnigricans mushroom can cause delayed-onset rhabdomyolysis with acute kidney injury in the severely poisoned patient. There are few reports on the toxicity of R. subnigricans. This report represents the first record of R. subnigricans poisoning with rhabdomyolysis in Korea, describing a 51-year-old man who suffered from rhabdomyolysis, acute kidney injury, severe hypocalcemia, respiratory failure, ventricular tachycardia, cardiogenic shock, and death. Mushroom poisoning should be considered in the evaluation of rhabdomyolysis of unknown cause. Furthermore, R. subnigricans should be considered in the mushroom poisoning with rhabdomyolysis.

    Effective management of cyanide poisoning from chemical terrorism, inhalation of fire smoke, and other causes constitutes a critical challenge for the prehospital care provider. The ability to meet the challenge of managing cyanide poisoning in the prehospital setting may be enhanced by the availability of the cyanide antidote hydroxocobalamin, currently under development for potential introduction in the United States. This paper discusses the causes, recognition, and management of acute cyanide poisoning in the prehospital setting with emphasis on the emerging profile of hydroxocobalamin, an antidote that may have a risk:benefit ratio suitable for empiric, out-of-hospital treatment of the range of causes of cyanide poisoning. If introduced in the U.S., hydroxocobalamin may enhance the role of the U.S. prehospital responder in providing emergency care in a cyanide incident.

    To analyze severe acute occupational poisoning accidents related to irritating gases reported in China between 1989 and 2003, and to study the characteristics of severe acute occupational poisoning accidents and provide scientific evidences for prevention and control strategies. The data from the national occupational poisoning case reporting system were analyzed with descriptive methods. (1) There were 92 severe acute occupational poisoning accidents related to asphyxiating gases during 15 years, which showed that there were 14.5 accidents occurred each year. Forty types of chemicals were reported to cause poisoning accidents directly. On average, there were 14.5 persons poisoned and 0.8 persons died of poisoning in each event. The number of death of poisoning reached 7 in most of the severe accidents. Chlorine was the main irritating gas resulting in poisoning accidents according to the number of accidents, cases and death. (1) The severe acute occupational poisoning related to irritating gases are more dangerous than others because of it is involved in more cases in each accident. (2) The accidents have concentricity in the certain types of chemicals, industries and jobs, and should be focused on control. (3) It is important to develop the program about early warning and forecast and the first aid.

    2010-01-01

    Full Text Available Objective: to evaluate the impact of oxidative stress intensity on hemorheological parameters in acute poisonings by psychopharmacological agents. Subjects and methods. The blood values of lipid peroxidation (LPO and the antioxidant system (AOS, and hemorheological parameters were determined in 196 patients with acute poisoning by psychopharmacological agents. Results. Mild poisoning was accompanied by a moderate rise in peroxidation processes, by compensated antioxidant activity, and by a decrease in hemorheological parameters. In moderate poisoning, and severe one in particular, there was an increase in the LPO/AOS imbalance attended by increases in the viscosity characteristics of blood and plasma and in the aggregation activity of platelets and red blood cells. Conclusion. As the intensity of oxidative stress increases, there are more severe impairments in blood viscosity and aggregation properties, the leading mechanism of which is damage to blood cells due to higher stiffness of their membranes and to plasma release of large-disperse molecules under the action of an excess of LPO products. Key words: oxidative stress, acute poisonings, hemorheology.

    Incidents of poisoning in humans caused by the ingestion of the glufosinate ammonium containing herbicides are gradually increasing in Japan. This poisoning is characterized by various neurological symptoms such as disturbances of consciousness, convulsions and apnea which appear after an asymptomatic interval of several hours. We studied the toxicokinetics of glufosinate in a patient with this poisoning successfully treated without extracorporeal hemopurification. A 65-year-old male ingested BASTA, which contains 20% w/v of glufosinate ammonium, about 300 ml, more than the estimated human toxic dose. Four and a half hours after ingestion, he showed speech ataxia and systemic tremor. He was prophylactically intubated before the occurrence of serious respiratory failure. After 5 days of artificial ventilation he was extubated and discharged without any sequelae. We studied the serial change of serum glufosinate concentration every 3-6 h and assessed the urinary excretion of glufosinate every 24 h. The absorbed amount of glufosinate was estimated from the cumulative excreted in urine. Toxicokinetic analysis was performed using the two-compartment model. The changes in serum glufosinate concentration exhibited T1/2alpha of 1.84 and T1/2beta of 9.59 h. The apparent distribution volume at beta-phase and the total body clearance were 1.44 l/kg and 86.6 ml/min, respectively. Renal clearance was estimated to be 77.9 ml/min. The indication for extracorporeal hemopurification for this poisoning has been discussed.

    This study evaluated the characteristics of orally poisoned patients admitted to our emergency department (ED) between January 1, 1998 and February 28, 2002. This study included 1098 patients. Poisoning cases annualy accounted for 0.5-1.3% of total patient admission during this period. The average age of the patients was 26y old. Poisoning was particulary common in students and housewives. Poisoning cases presented to the ED most commonly between 6 pm and 12 am (38%). More than half of study patients (52%) were admitted to the ED within 2 h of exposure. The incidence of concomitant alcohol intake with another intoxicant was 11%. The ingested drugs were 32% various antidepressants, 23% paracetamol, 20% analgesics (excluding paracetamol and salicylates), 10% antibiotics, 9% benzodiazepines, 7% salicylates and 7% cardiovascular drugs. Most patients received at least 1 of the following treatments: gastric lavage, oral activated charcoal, iv hydration, or diuresis. Thirty-two percent of patients were hospitalized beyond 24 h and 68% of were discharged within 24 h. The mortality rate of the overall cohort was < 1%. Psychiatric consultation was obtained for 55% of patients.

    Full Text Available The honey bee is credited with approximately 85% of the pollinating activity necessary to supply about one-third of the world’s food supply. Well over 50 major crops depend on these insects for pollination. The crops produce more abundantly when honey bees are plentiful. Worker bees are the ones primarily affected by pesticides. Poisoning symptoms can vary depending on the developmental stage of the individual bee, and the kind of chemical employed. The oral toxicity of these insecticides: (phosalone and pirimicarb, acaricide (propargite, insecticide and acaricide (fenpropathrin, fungicides, and bactericides (copper oxychloride and the Bordeaux mixture, were evaluated for the purposes of this research. The results showed that fenpropathrin had high acute oral toxicity (LC50-24h and LC50-48 were 0.54 and 0.3 ppm, respectively. Propargite had 7785 ppm (active ingredient for LC50-24h and 6736 ppm (active ingredient for LC50-48h in honeybees and is therefore, non-toxic to Apis mellifera. On the other hand, copper oxychloride had minimum acute oral toxicity to honeybees (LC50-24h and LC50-48 were 4591.5 and 5407.9 ppm, respectively and was therefore considered non-toxic. Also, the Bordeaux mixture was safe to use around honeybees. Phosalone and primicarb were considered highly and moderately toxic to honeybees, respectively.

    Full Text Available Acute carbon monoxide (CO poisoning with cardiac complications is well documented in the literature. However, ST segment elevation is a rare presentation, and most of these cases with ST elevation have revealed non-occlusive or normal coronary arteries. We report a case of CO poisoning complicated with ST elevation myocardial infarction. Emergency coronary angiography revealed total occlusion of the left anterior descending artery and primary percutaneous coronary intervention was performed. This report of a rare case should remind physicians that cardiovascular investigations, including electrocardiography, must be performed in cases with CO poisoning because mortality might increase if reperfusion therapy or appropriate medical treatments are not performed in patients with acute coronary artery occlusion.

    To study an influence of chronic alcoholism on the clinical course and severity of metabolic disturbances in patients with acute poisoning with ethanol and to improve the treatment. Authors examined 93 patients stratified into three groups (acute poisoning with ethanol in patients with chronic alcoholism, without chronic alcoholism and those treated with reamberin). The presence of chronic alcoholism significantly augmented metabolic disturbances and influenced the disturbance of oxygen-transport function and free-radical processes in patients with acute intoxication with ethanol. Using of reamberin in the complex intensive therapy led to the decrease in metabolic disorders, which improved the clinical course of acute poisoning with ethanol in patients with chronic alcoholism.

    2005-01-01

    Full Text Available Background/Aim. Pneumonia is the most frequent complication in acute psychotropic drugs poisoning, which results in substantial morbidity and mortality, but which also increases the costs of treatment. Risk factors for pneumonia are numerous: age, sex, place of the appearance of pneumonia, severity of underlying disease, airway instrumentation (intubation, reintubation, etc. The incidence of pneumonia varies in poisoning caused by the various groups of drugs. The aim of this study was to determine the incidence and risk factors for pneumonia in the patients with acute psychotropic drugs poisoning. Methods. A group of 782 patients, out of which 614 (78.5% with psychotropic and 168 (21.5% nonpsychotropic drug poisoning were analyzed prospectively during a two-year period. The diagnosis of pneumonia was made according to: clinical presentation, new and persistent pulmonary infiltrates on chest radiography, positive nonspecific parameters of inflammation, and the microbiological confirmation of causative microorganisms. To analyze predisposing risk factors for pneumonia, the following variables were recorded: sex, age, underlying diseases, endotracheal intubation, coma, severity of poisoning with different drugs, histamine H2 blockers, corticosteroids, mechanical ventilation, central venous catheter. The univariate analysis for pneumonia risk factors in all patients, and for each group separately was done. The multivariate analysis was performed using the logistic regression technique. Results. Pneumonia was found in 94 (12.02% of the patients, 86 of which (91.5% in psychotropic and 8 (8.5% in nonpsychotropic drug poisoning. In the psychotropic drug group, pneumonia was the most frequent in antidepressant (47%, and the rarest in benzodiazepine poisoning (3.8%. A statistically significant incidence of pneumonia was found in the patients with acute antidpressant poisoning (p < 0.001. Univariate analysis showed statistical significance for the

    Full Text Available Introduction. Acute exposure to the effects of volatile solvents is characterized by the abrupt onset of symptoms and signs of poisoning, and relatively fast recovery in the majority of cases. Case report. We report a 24-year-old patient with an acute, accidental poisoning with a mixture of volatile organic solvents (most probably toluene, styrene and xylene, which led to the development of upward gaze paresis, diplopia, hemiparesis, ataxic gate, and the late onset truncal ataxia episodes. After 6 weeks, he recovered completely, while his extensive brain MRI lesions in the caudate nuclei, laterobasal putaminal regions, bilateral anterior insular cortex, central midbrain tegmental area withdrew completely after 4 months. Conclusion. Acute toxic encephalopathy should be a part of the differential diagnosis in any patient with acute neurobehavioral and neurological deficit.

    Incidences of mortality of Indian peafowl Pavo cristatus, the national bird (Schedule I Indian Wild Life Protection Act 1972), are rampant in India. Between January 2011 and March 2017, around 550 peafowl in 35 incidences were reported dead across the country. Due to the non-availability of fresh carcases, poisoning could not be confirmed. Birds which died due to kite string injuries in Ahmedabad (15) and accidents in Coimbatore (5) were tested for residues of chlorinated pesticides, namely hexachlorocyclohexane (HCH), dichloro-diphenyl-trichloroethane (DDT), endosulfan, heptachlor, dicofol, dieldrin and cholipyrifos. The liver, kidney and muscle were the tissues considered to document pesticide load. Total load ranged from BDL to 388.2 ng/g. DDT (95%) and HCH (80%) were detected more frequently. DDT (40%) and endosulfan (26%) contributed maximum to the total pesticide load followed by HCH (21%). Pesticide accumulation pattern among the organs was in the order of liver (123.9 ng/g) > kidney (91.9 ng/g) > muscle (19.5 ng/g) with significant difference (p pesticide (149.0 ng/g) than birds from Coimbatore (47.8 ng/g). Although varying levels of chlorinated pesticide were detected, they were below reported toxic limits. Nevertheless, persistence of chlorinated pesticides and poisoning due to modern pesticides across the entire distribution range of Peafowl in India is a cause for concern.

    Procedures for the clinical assessment of acute poisoning by substances of abuse should identify patients in need of hospital admission and avoid hazardous discharges, while keeping the observation time short. We assess the safety of a systematic procedure developed at the Oslo Accident and Emergency Outpatient Clinic (OAEOC). All patients 12 years and older treated for acute poisoning by substances of abuse at the OAEOC were included consecutively from October 2011 to September 2012. Data were collected on pre-set registration forms. Information on re-presentations to health services nation-wide during the first week following discharge was retrieved from the Norwegian Patient Register and from local electronic medical records. Information on fatalities was obtained from the Norwegian Cause of Death Registry. There were 2343 cases of acute poisoning by substances of abuse. The main toxic agent was ethanol in 1291 (55 %) cases, opioids in 539 (23 %), benzodiazepines in 194 (8 %), central stimulants in 132 (6 %), and gamma-hydroxybutyrate (GHB) in 105 (4 %). Median observation time was four hours. The patient was hospitalised in 391 (17 %) cases. Two patients died during the first week following discharge, both from a new opioid poisoning. Among 1952 discharges, 375 (19 %) patients re-presented at the OAEOC or a hospital within a week; 13 (0.7 %) with a diagnosis missed at the index episode, 169 (9 %) with a new poisoning, 31 (2 %) for follow-up of concomitant conditions diagnosed at index, and 162 (8 %) for unrelated events. Among the patients with missed diagnoses, five needed further treatment for the same poisoning episode, two were admitted with psychosis, one had hemorrhagic gastritis, another had fractures in need of surgery and four had minor injuries. The procedure in use at the OAEOC can be considered safe and could be implemented elsewhere. The high re-presentation rate calls for better follow-up.

    Large, prospective pre-hospital studies of acute poisonings are scarce. We present the epidemiology of the pre-hospital poisonings, the treatment given, the complications of the poisoning itself and the treatment, predictors for hospitalization, and the safety of the present approach in a large industrial Russian city. Data were collected from March 2009 to March 2010. All adult (≥ 16 years) acute poisonings in the city of Yekaterinburg, Russia were included. The prospective cohort inclusion of data included age, gender, simple clinical features (including consciousness, respiratory status, circulatory status, convulsions, etc.), main toxic agent, reason why poisoning was suspected, treatment given, and outcome. Multivariate logistic regression analysis was used to identify the factors associated with hospitalization of the patients. In total, 1795/2536 patients (71%) were brought to hospitals, 736/2536 (29%) were discharged by the ambulance, and 5/2536 (0.2%) died on scene. The most frequent main agents were opioids (25%), ethanol (9%), benzodiazepines (8%), corrosive substances (7%), carbon monoxide (5%), and neuroleptics (5%). Pre-hospital treatment was given to 73% of patients; 3% were intubated, and antidotes were given in 27% (naloxone 24%, atropine 2%, and flumazenil 0.2%). Gastric lavage was performed in 34%, but only 20% within the first hour after ingestion; 49% had a Glasgow Coma Scale (GCS)treatment practice in most places, especially concerning the use of gastric lavage. Whether the current practice led to an increased morbidity and mortality is uncertain, but it justifies the need for thorough evaluation of clinical practice. These findings highlight the importance of studies like the present to improve diagnostics, triage, and treatment in acute poisonings.

    Although scarce, the data about acute poisonings with psycho-active substances during the period of socioeconomic crisis in Bulgaria indicate the appearance and increase of the use of inhalants, prescribed and over-the-counter medications and the increase of acute poisoning rate with heroin. To ascertain some characteristics of acute poisonings with psycho-active substances in Plovdiv region from 01.01.1990 to 31.12.2000. The whole caseload of 571 acute poisonings with psycho-active substances in Plovdiv region (8.8% of the population of the country) between 1990 and 2000, treated in the only Clinic of Toxicology in the region is studied retrospectively. The variables gender, age, type of psycho-active substance (DSM-IV criteria), grade of severity, duration of use, times of poisoning and some differences between alcohol and opioid poisonings are investigated. Acute poisoning with psycho-active substances are 5.43% of all intoxications. The moderate grade of severity (48.5%), alcohol (62.8%) and opioid (15.3%) intoxications, debut poisoning (86.8%) and poisonings occurring in the initial period of use predominate. An increase of acute poisonings with psycho-active substances in the last third of the studied period (1990-2000) is established--severe forms (2.59 times) and recidivistic intoxication (4 times). Alcohol and opioid poisonings predominate among severe intoxications. The hospital stay is relatively short--1.75 +/- 0.67 and hospital lethality is 1.6%. 1. The moderate grade of severity, alcohol and opioid intoxications (especially in the severe grade cases), occurrence in the initial period of use and relatively short hospital stay predominate in acute poisonings with psycho-active substances in the period of socioeconomic crisis. Hospital lethality (1.6%) is ascertained only in severe alcohol intoxication. 2. An increase of acute poisonings with psycho-active substances--severe forms, mild forms and recidivistic intoxications is established in the last

    Eleven magnetic resonance (MR) and computed tomographic (CT) imaging were performed in nine patients with mild to moderate degree of delayed neuropsychiatric symptoms following acute carbon monoxide (CO) poisoning, to evaluate the capability of MR in demonstrating any additional finding to CT. The MR images were obtained using 0.15 Tesla resistive system with various combination of three pulse sequences, including partial saturation recovery, T2-weighted spin echo and inversion recovery. Bilateral white matter abnormalities suggesting demyelination were demonstrated in 4 patients with MR and in only 2 patients with CT. The contrast discrimination between normal and abnormal white matter proved to be better with T2-weighted spin echo and inversion recovery than with partial saturation recovery and CT. But necrosis of the globus pallidus (1 patient) and diffuse atrophy (3 patients) were equally demonstrated on both MR and CT. It is suggested that MR be used as a initial imaging method in the evaluation of the delayed encephalopathy following acute CO poisoning, especially for the detection of the possible white matter lesions. Acute carbon monoxide (CO) poisoning produces hypoxia by displacing oxygen from hemoglobin and preventing its release from hemoglobin in tissues, often resulting in fetal event. Victims who survive acute CO poisoning may have various delayed symptoms and signs. Occasionally, an apparent recovery is followed within two days to three weeks by a sudden neurological deterioration. The degree of neuropsychiatric symptoms depends upon the extent and severity of the pathologic changes in the brain. The pathologic effects of CO poisoning are present in almost all organs of patients. However, the most important changes occur in the brain, which consist of necrosis of the globus pallidus and reticular zone of the substantia nigra, and the degeneration of the cerebral white matter. The diagnostic superiority of magnetic resonance (MR) over CT has already

    The present study investigated the predictive values of urine paraquat (PQ) concentration, dose of poison, arterial blood lactate and Acute Physiology and Chronic Health Evaluation (APACHE) II score in the prognosis of patients with acute PQ poisoning. A total of 194 patients with acute PQ poisoning, hospitalized between April 2012 and January 2014 at the First Affiliated Hospital of P.R. China Medical University (Shenyang, China), were selected and divided into survival and mortality groups. Logistic regression analysis, receiver operator characteristic (ROC) curve analysis and Kaplan-Meier curve were applied to evaluate the values of urine paraquat (PQ) concentration, dose of poison, arterial blood lactate and (APACHE) II score for predicting the prognosis of patients with acute PQ poisoning. Initial urine PQ concentration (C0), dose of poison, arterial blood lactate and APACHE II score of patients in the mortality group were significantly higher compared with the survival group (all Ppoison and arterial blood lactate correlated with mortality risk of acute PQ poisoning (all Ppoison, arterial blood lactate and APACHE II score in predicting the mortality of patients within 28 days were 0.921, 0.887, 0.808 and 0.648, respectively. The AUC of C0 for predicting early and delayed mortality were 0.890 and 0.764, respectively. The AUC values of urine paraquat concentration the day after poisoning (Csec) and the rebound rate of urine paraquat concentration in predicting the mortality of patients within 28 days were 0.919 and 0.805, respectively. The 28-day survival rate of patients with C0 ≤32.2 µg/ml (42/71; 59.2%) was significantly higher when compared with patients with C0 >32.2 µg/ml (38/123; 30.9%). These results suggest that the initial urine PQ concentration may be the optimal index for predicting the prognosis of patients with acute PQ poisoning. Additionally, dose of poison, arterial blood lactate, Csec and rebound rate also have referential significance.

  19. Lead Poisoning Can Be Easily Misdiagnosed as Acute Porphyria and Nonspecific Abdominal Pain

    2017-01-01

    Full Text Available Lead poisoning (LP is less commonly encountered in emergency departments (ED. However, lead exposure still occurs, and new sources of poisoning have emerged. LP often goes unrecognized due to a low index of suspicion and nonspecific symptoms. We present a case of a 48-year-old man who had recurring abdominal pain with anemia that was misdiagnosed. His condition was initially diagnosed as nonspecific abdominal pain and acute porphyria. Acute porphyria-like symptoms with a positive urine porphyrin test result led to the misdiagnosis; testing for heme precursors in urine is the key to the differential diagnosis between LP and acute porphyria. The final definitive diagnosis of lead toxicity was confirmed based on high blood lead levels after detailed medical history taking. The lead poisoning was caused by traditional Chinese herbal pills. The abdominal pain disappeared after a course of chelating treatment. The triad for the diagnosis of lead poisoning should be a history of medicine intake, anemia with basophilic stippling, and recurrent abdominal pain.

    During an outbreak of mass methanol poisoning in the Czech Republic in 2012-2014, we compared the total hospital costs and one-year medical costs in the patients treated with different antidotes (fomepizole versus ethanol) and modalities of hemodialysis (intermittent hemodialysis, IHD, versus continuous renal replacement therapy, CRRT). Cross-sectional study in 106 patients with confirmed diagnosis treated in 30 ICU settings. For each patient, the following data were analyzed: admission laboratory data, GCS, PSS, ICU length of stay, organ failures, treatment, outcome, and total hospital costs. Of 83 survivors, in 54 (65%) patients the follow-up examination, quality of life measurement with SF36 questionnaire two years after discharge, and one-year medical costs analysis were performed. The median total hospital costs were 7200 (IQR 1500-10,900) euros and the median one-year medical costs were 1447 (IQR 133-1163) euros in the study population. The total hospital costs were higher in the patients treated with fomepizole comparing to ethanol: 12,890 (IQR 6910-16,210) versus 5590 (IQR 1430-6940) euros (ppoisoning was 3.30 (1.70-3.80 CI 95%), p0.05). The total hospital costs in the patients with acute methanol poisoning were more than three times higher in the patients treated with fomepizole than in the patients treated with ethanol after adjustment for the severity of poisoning. The dialysis modality did not affect the total hospital costs, but the trend to lower costs was present in IHD-group. Copyright © 2017 Elsevier Inc. All rights reserved.

  1. Emergency department management of children with acute isoniazid poisoning.

    Science.gov (United States)

    Parish, R A; Brownstein, D

    1986-06-01

    We suggest that the following therapeutic regimen be followed in cases of isoniazid poisoning in children. In cases of intractable seizure activity in a child which remains unexplained, consider isoniazid poisoning. Give pyridoxine as an intravenous bolus to all children in whom isoniazid toxicity is suspected, who exhibit seizure activity and are known to have been exposed to isoniazid, or who have a history of ingesting one gram or more of isoniazid. It should be given on a gram-for-gram basis, and the clinician need not await serum isoniazid levels before administering pyridoxine. It can be safely given at a rate of five grams per three minutes in a 50 ml volume. In fact, serum isoniazid determinations are not available in many emergency departments and have not been shown to correlate closely with symptomatology. When available, serum isoniazid levels at best are subject to variability owing to sampling procedures (serum protein must be removed within two hours of sampling). The result is that serum isoniazid levels play only a minor role in the emergency department management of isoniazid poisoning. To potentiate the antidotal effects of pyridoxine, diazepam (0.1 mg/kg) may be given intravenously, preferably at a second intravenous site. Because the lactic acidosis seen after seizures resolves spontaneously, and because metabolic alkalosis may result following excess lactate loading, administration of bicarbonate is usually not necessary, and may be harmful in some cases. After pyridoxine treatment, syrup of ipecac may be given to empty the stomach.(ABSTRACT TRUNCATED AT 250 WORDS)

    A descriptive retrospective study of acute intoxication cases registered at the Complexo Hospitalario de Pontevedra (CHOP) between January 2005 and December 2008 was performed to find out the number and types of poisoning cases treated, their distribution according to patient's sex and age, chronology, type of toxic agents involved, intentionality, history, symptoms, clinical development, treatment and toxicological analysis used for diagnosis. Data were recorded using Clinica and IANUS software and consulting all paper records of patients with symptoms of poisoning. Data from a total of 1893 patients with a mean age of 35.6 ± 17.6 years (66% men) were included. Highest rates of poisoning were recorded on Saturdays and Sundays during the summer months (June, July and August). Drugs of abuse were the most common toxic agents (70.4%), ethyl alcohol accounting for 61% of these cases, which often involved males and with people with high degrees of dependency. In second place was poisoning resulting from the abuse of medical drugs, more commonly associated with females, and involving benzodiazepines in 73.2% of cases. The majority of these intoxications were intentional, and suicide attempts accounted for 18.8%. The problems most commonly resulting from the poisoning were neurological, and mortality rate was just 0.2%.

  3. Ulinastatin suppresses endoplasmic reticulum stress and apoptosis in the hippocampus of rats with acute paraquat poisoning

    Full Text Available Lung injury is the main manifestation of paraquat poisoning. Few studies have addressed brain damage after paraquat poisoning. Ulinastatin is a protease inhibitor that can effectively stabilize lysosomal membranes, prevent cell damage, and reduce the production of free radicals. This study assumed that ulinastatin would exert these effects on brain tissues that had been poisoned with paraquat. Rat models of paraquat poisoning were intraperitoneally injected with ulinastatin. Simultaneously, rats in the control group were administered normal saline. Hematoxylin-eosin staining showed that most hippocampal cells were contracted and nucleoli had disappeared in the paraquat group. Fewer cells in the hippocampus were concentrated and nucleoli had disappeared in the ulinastatin group. Western blot assay showed that expressions of GRP78 and cleaved-caspase-3 were significantly lower in the ulinastatin group than in the paraquat group. Immunohistochemical findings showed that CHOP immunoreactivity was significantly lower in the ulinastatin group than in the paraquat group. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining showed that the number of apoptotic cells was reduced in the paraquat and ulinastatin groups. These data confirmed that endoplasmic reticular stress can be induced by acute paraquat poisoning. Ulinastatin can effectively inhibit this stress as well as cell apoptosis, thereby exerting a neuroprotective effect.

  4. Using bosentan to treat paraquat poisoning-induced acute lung injury in rats.

    Directory of Open Access Journals (Sweden)

    Zhongchen Zhang

    Full Text Available BACKGROUND: Paraquat poisoning is well known for causing multiple organ function failure (MODS and high mortality. Acute lung injury and advanced pulmonary fibrosis are the most serious complications. Bosentan is a dual endothelin receptor antagonist. It plays an important role in treating PF. There is no related literature on the use of bosentan therapy for paraquat poisoning. OBJECTIVE: To study the use of bosentan to treat acute lung injury and pulmonary fibrosis as induced by paraquat. METHOD: A total of 120 adult Wister male rats were randomly assigned to three groups: the paraquat poisoning group (rats were intragastrically administered with paraquat at 50 mg/kg body weight once at the beginning; the bosentan therapy group (rats were administered bosentan at 100 mg/kg body weight by intragastric administration half an hour after paraquat was administered, then the same dose was administered once a day; and a control group (rats were administered intragastric physiological saline. On the 3rd, 7th, 14th, and 21st days following paraquat exposure, rats were sacrificed, and samples of lung tissue and venous blood were collected. The levels of transforming growth factor-β1 (TGF-β1, endothelin-1 (ET-1, and hydroxyproline (HYP in the plasma and lung homogenate were determined. Optical and electronic microscopes were used to examine pathological changes. RESULT: The TGF-β1, ET-1, and HYP of the paraquat poisoning group were significantly higher than in the control group, and they were significantly lower in the 21st day therapy group than in the paraquat poisoning group on the same day. Under the optical and electronic microscopes, lung tissue damage was observed to be more severe but was then reduced after bosentan was administered. CONCLUSION: Bosentan can reduce inflammation factor release. It has a therapeutic effect on acute lung injury as induced by paraquat.

    In Oslo, the majority of patients with acute poisoning are treated in primary care, at an emergency outpatient clinic with limited diagnostic and treatment resources. We describe the poisonings currently seen in this setting. We compare our findings with previous studies, with special concern for the appearance of new toxic agents, and changes in overall numbers and patterns of poisoning. Observational study. Patients above the age of 12 years presenting at Oslo Accident and Emergency Outpatient Clinic (Oslo Legevakt) with acute poisoning were included consecutively from October 2011 through September 2012. Physicians and nurses registered data on preset forms. Main outcome measures were toxic agents, age, sex, intention, referral and time of presentation. There were 2923 episodes of acute poisoning in 2261 patients. Median age of the patients was 32 years, and 1430 (63%) were males. The most frequent toxic agents were ethanol in 1684 (58%) episodes, heroin in 542 (19 %), benzodiazepines in 521 (18%), amphetamine in 275 (9%), fire smoke in 192 (7%), gamma-hydroxybutyrate (GHB) in 144 (5%), and cannabis in 143 (5%). In 904 (31%) poisonings there were more than one toxic agent. In 493 episodes (17%), the patient was hospitalised, and in 60 episodes (2%) admitted to a psychiatric ward. Most poisonings, 2328 (80%), were accidental overdoses with substances of abuse, 276 (9%) were suicide attempts, and 312 (11%) were accidents. Among ethanol poisonings in patients above the age of 26 years, 685/934 (73%) were in males, and 339/934 (36%) presented during weekends. However, among ethanol poisonings in patients under the age of 26 years, 221/451 (49 ) were in females, and 297/451 (66%) presented during weekends. The poisonings treated in this primary care setting were mostly due to accidental overdoses with ethanol or other substances of abuse. There is a disconcerting weekend drinking pattern among adolescents and young adults, with young females presenting as often as

    Full Text Available Background: Copper sulfate ingestion is a relatively popular method for committing suicide in Indian subcontinent. It causes a high mortality rate, and so a growing concern has been raised to identify the severe alarming signs suggestive of poor prognosis and to improve treatment approaches. Case report: A 22-year-old unmarried man working as a painter was found unconscious at his friend residence. The patient developed hypotension, hemorrhagic gastroenteritis with hematemesis and melena, renal and hepatic failure, severe metabolic acidosis and intravascular hemolysis during admission at hospital. His signs were refractory to treatment with fluid replacement therapy, vasoactive drugs, antiemetic drugs, ranitidine, furosemide, methylene blue and 2,3 dimercaptopropane-1-sulphonate. He died six hours post-admission. In post-mortem examinations, there were multiple sub-pleural and sub-epicardial hemorrhages and the gastrointestinal mucosa was congested, hemorrhagic, and greenish blue in color. The liver, on histological examination, showed sub-massive hepatic necrosis. On toxicological analyses, copper sulfate was detected in preserved viscera and results for other heavy metals were negative. Conclusion: Hypotension, cyanosis, uremia and jaundice can be considered as signs of poor prognosis in copper sulfate poisoning. Copper sulfate ingestion is life-threatening due to its deleterious effects on the upper GI, kidneys, liver and blood. Having no time to waste, aggressive treatments should be immediately instituted and signs of poor prognosis should be kept in mind.

    Full Text Available Background/Aim. Although chlorpromazine (CPZ is an antipsychotic drug widely used in clinical practice for a long time, its mechanism of action has not been entirely defined. An extremely difficult managing of patients acutely poisoned with CPZ is additional reason for detailed studying its toxicity mechanisms. In this clinical study, we investigated whether the oxidative stress (OS mediates CPZ toxic effects in the exposed patients. Methods. The patients were organized into 3 groups: the T-group - hospitalized patients receiving therapeutic doses of 75-150 mg CPZ/day; the overdosed group, divided into two subgroups: the group M and the group S - mildly (CPZ serum concentration: 0.21 ± 0.05 mg/L and severely (CPZ serum concentration: 2.66 ± 0.25 mg/L poisoned patients, respectively, and the group C (control group of healthy volunteers. Oxidative stress parameters [total antioxidative status (TAS and malondialdehyde (MDA in plasma] and superoxide dismutase (SOD activity in erythrocytes were measured spectrophotometrically, and CPZ concentrations in serum were monitored chromatographically. One set of measurements was performed in the group C and T, whereas two sets of measurements (after 24 hours and 48 hours were done in the poisoned patients, groups M and S. Results. A decrease of TAS and increase of SOD activity were obtained in both subgroups of the poisoned patients, compared to the controls and the group receiving therapeutic doses of CPZ. A significant increase of MDA was achieved in severely poisoned patients, compared to all other groups. Conclusion. Changed oxidative stress parameters in patients poisoned with chlorpromazine indicate involvement of oxidative stress in the toxicity mechanism(s of chlorpromazine.

    The increase in agricultural activity that Chile experienced in the past 20 years resulted in a boost in the use of pesticides. Despite pesticides' productivity benefits, they caused health problems such as the increased frequency of episodes of acute poisoning, which constitutes a relevant problem in terms of occupational health. The Chilean authorities require several preventive measures at workplaces, which are not always implemented, increasing the risk of intoxications in farmers. So far in Chile, there are no studies concerning the public health care expenses associated with acute work-related pesticide intoxications. From the societal perspective, there are costs involved if the worker needs to take sick leave and families incur costs to take care of their sick members. This study aimed to determine the costs associated with health care services used by people who suffered from work-related acute pesticide poisoning, as well as the economic costs for the families of the workers involved, and finally the costs of these episodes for the employer/industrial sector. This study considered a 3-year period (January 2009 to December 2011). Three sources of data were reviewed: reported cases at the Regional Health Authority, for the profile of the intoxications; registers of patients attended in public hospitals, for data on costs of health care services; and public information of living conditions nationwide. The overall costs of a single case depend on the severity of intoxication, days of sick leave, and type of health care needed. Most cases (77%) would be ambulatory and would be assisted at an emergency room, with an average cost of US $330 per case. Those cases that might need hospitalization (23%) and, therefore, more days off work have an average cost of US $1158 per case. Taking into account the number of patients reported each year in the country, the cost per annum would be about US $185,000, but considering the underreporting of intoxications and

    To determine accidental factors, clinical presentation and medical care in cases of seafarers presenting phosphine poisoning symptoms on board a bulk carrier. To consider primary prevention of this pathology, which can have extremely severe consequences. To analyse circumstances resulting in toxic exposure to phosphine in the sea transport sector. To obtain information from medical reports regarding the seafarer's rescue. To identify the causes of this accidental poisoning and how to establish an early, appropriate diagnosis thus avoiding other cases. In February 2008, on board a bulk carrier with a cargo of peas, a 56-year-old seafarer with intense abdominal and chest pains, associated with dizziness, was rescued by helicopter 80 miles away from the coast. Despite being admitted rapidly to hospital, his heart rate decreased associated with respiratory distress. He lost consciousness and convulsed. He finally died of pulmonary oedema, major metabolic acidosis and acute multi organ failure. The following day, the captain issued a rescue call from the same vessel for a 41-year-old man also with abdominal pain, vomiting and dizziness. The ECG only revealed type 1 Brugada syndrome. Then 11 other seafarers were evacuated for observation. 3 showed clinical abnormalities. Collective poisoning was suspected. Medical team found out that aluminium phosphide pellets had been put in the ship's hold for pest control before the vessel's departure. Seafarers were poisoned by phosphine gas spreading through cabins above the hold. It was found that the compartments and ducts were not airtight. Unfortunately, a seafarer on board a bulk carrier died in 2008 because of acute phosphine poisoning. Fumigation performed using this gas needs to be done with extreme care. Systematic checks need to be carried out before sailing to ensure that the vessel's compartments are airtight.

    Full Text Available Introduction. During the last few years, intravenous lipid emulsions have been effectively used in treatment of acute poisonings with lipophilic substances, including verapamil. Case report. A 37-year-old women presented 1 hour after ingestion of 2.8 g verapamil with hypotension and complete heart block. Because of the applied standard therapy failure and further patients impairment, Intralipid® 20% was used. Sinus rhythm was restored, arterial blood pressure increased and verapamile concentrations, both total and free decreased. Conclusion. Intravenous lipid emulsion can be important in treatment of severe acute intoxication and cardiotoxicity caused by verapamil.

    The duration of hemodialysis (HD) in methanol poisoning (MP) is dependent on the methanol concentration, the operational parameters used during HD, and the presence and severity of metabolic acidosis. However, methanol assays are not easily available, potentially leading to undue extension or premature termination of treatment. Here we provide a prediction model for the duration of high-efficiency HD in MP. In a retrospective cohort study, we identified 71 episodes of MP in 55 individuals who were treated with alcohol dehydrogenase inhibition and HD. Four patients had residual visual abnormality at discharge and only one patient died. In 46 unique episodes of MP with high-efficiency HD the mean methanol elimination half-life (T1/2) during HD was 108 min in women, significantly different from the 129 min in men. In a training set of 28 patients with MP, using the 90th percentile of gender-specific elimination T1/2 (147 min in men and 141 min in women) and a target methanol concentration of 4 mmol/l allowed all cases to reach a safe methanol of under 6 mmol/l. The prediction model was confirmed in a validation set of 18 patients with MP. High-efficiency HD time in hours can be estimated using 3.390 × (Ln (MCi/4)) for women and 3.534 × (Ln (MCi/4)) for men, where MCi is the initial methanol concentration in mmol/l, provided that metabolic acidosis is corrected.

  16. Acute oxalate nephropathy caused by ethylene glycol poisoning

    2012-12-01

    Full Text Available Ethylene glycol (EG is a sweet-tasting, odorless organic solvent found in many agents, such as anti-freeze. EG is composed of four organic acids: glycoaldehyde, glycolic acid, glyoxylic acid and oxalic acid in vivo. These metabolites are cellular toxins that can cause cardio-pulmonary failure, life-threatening metabolic acidosis, central nervous system depression, and kidney injury. Oxalic acid is the end product of EG, which can precipitate to crystals of calcium oxalate monohydrate in the tubular lumen and has been linked to acute kidney injury. We report a case of EG-induced oxalate nephropathy, with the diagnosis confirmed by kidney biopsy, which showed acute tubular injury of the kidneys with extensive intracellular and intraluminal calcium oxalate monohydrate crystal depositions.

    Full Text Available Methoxetamine (MXE is a psychoactive substance distributed mostly via the Internet and is not liable to legal regulation in Poland. MXE has a toxicity profile similar to that of ketamine but longer-lasting effects. The paper describes a case of acute poisoning that resulted from recreational use of MXE and amphetamine and ended in death. In mid-July 2012, a 31-year old man was admitted to the clinical toxicology unit in Gdańsk because of poisoning with an unknown psychoactive substance. The patient was transported to the emergency department (ED at 5:15 a.m. in a very poor general condition, in a deep coma, with acute respiratory failure, hyperthermia (> 39°C and generalized seizures. Laboratory tests showed marked leukocytosis, signs of massive rhabdomyolysis, hepatic failure and beginning of acute renal failure. Despite intensive therapy, the patient died 4 weeks after the poisoning in the course of multi-organ dysfunction syndrome. Chemical and toxicological studies of serum and urine samples collected on the poisoning day at 1:40 p.m. confirmed that amphetamine and MXE had been taken earlier that day. Concentration of amphetamine in the serum (0.06 μg/ml was within the non-toxic range, while MXE (0.32 μg/ml was within the toxic range of concentrations. Amphetamine was also detected in the patient's hair, which suggested a possibility of its use within the last dozen weeks or so. The serious clinical course of intoxication and co-existence of amphetamine and MXE in the patient's blood and urine suggest the possibility of adverse interactions between them.

  19. INAA determination of As in sectional hair samples for forensic purposes: Chronic or acute poisoning?

    2009-01-01

    Autopsy of a 29-year old woman suspect of having committed suicide by ingestion of As 2 O 3 yielded contradictory findings. ICP-MS revealed a highly elevated As level in hair collected during the autopsy , viz. 26.4 μg.g -1 , indicating chronic arsenic poisoning, whereas all clinical symptoms and pathological findings suggested acute poisoning. To elucidate this discrepancy, INAA of sectional hair samples obtained from a hair-brush of the deceased woman was performed. The As levels found, viz. 0.06 to 0.26 μg.g -1 , ruled out chronic poisoning because the woman died approximately 14 hours after ingestion of As 2 O 3 . Two reasons for the discordant results are considered: (1) accidental, non-removed contamination of hair during As 2 O 3 ingestion; (2) wrong ICP-MS procedure. A brief review is also presented of As determination in hair for forensic purposes, including the issue of the supposed and still frequently discussed poisoning of Napoleon Bonaparte

    Full Text Available Background: Tramadol is an analgesic drug being abused today a lot. Excessive ingestion will lead to hazardous complications such as convulsion and occasionally respiratory apnea. The aim of this study based on frequency respiratory apnea in patients with acute tramadol poisoning hospitalized in Farshchian Hospital of Hamadan, Iran from Jan 2014 to Dec 2015. Methods: All patients with tramadol poisoning who hospitalized and treated at poisoning ward were enrolled into the study. Their demographic data including age, gender, drug ingestion dose, and respiratory apnea leading to taking naloxone or intubation collected and analyzed statistically by SPSS software. Results: Overall, 350 patients aged between 14 to 68 yr old were investigated. About 75% of them were male and among them, 81.14% had deliberate self-poisoning. 4.86% developed apnea whose average tramadol consumption was 4158.83 mg. In patients who had not apnea, the average tramadol consumption was 122.38 mg, that was statistically significant difference (P<0.001. Conclusion: Although apnea development frequency in patients with excessive tramadol ingestion is rare, it is significant as a potentially life-threatening risk, occasionally ignored.

    To analyze clinical feature and evaluate long-term outcome of patients with thallium poisoning. An observational series of cases with acute thallium poisoning was analyzed retrospectively in West China Hospital of Sichuan University between 2000 and 2010. The clinical data including symptom, determination of thallium level, treatment, neurophysiological examination, and neuropsychological evaluation were analyzed. The patients were followed up until December 2012. Seven men and six women were enrolled in the study. The median patient age was 37 years (range: 15-53 years). The median duration of hospitalization was 44 days (range: 7-72). All the patients were misdiagnosed initially. One patient died in the hospital. The other 12 patients were followed for a median of 7 years (range: 1-12 years) after discharge from hospital. One patient died from leukemia in the first year of follow-up. Long-term outcome results showed peripheral neuropathy improved substantially. However, many patients have mild or moderate sequelae in sensory nerve fibers of distal lower extremity. A sural nerve biopsy in one patient revealed shrunken axons, distorted myelin sheath, and myelinated fibers loss. During follow-up period, problem of intelligence (4/12 patients, 33%), memory impairment (4/12, 33%), anxiety (6/12, 50%), and depression (5/12, 42%) were demonstrated. Neurological symptoms may lead to misdiagnosis of thallium poisoning. Mild or moderate neurological sequelae may last for a long time after thallium poisoning.

    To analyze severe acute occupational poisoning accidents related to organic solvents reported in China between 1989 and 2003, and to study the characteristics of severe acute occupational poisoning accidents and provide scientific evidences for prevention and control strategies. The data from the national occupational poisoning case reporting system were analyzed with descriptive methods. (1) There were 58 severe acute occupational poisoning accidents related to organic solvents for 15 years with 393 workers poisoned and 48 workers died. The total poisoning rate was 51.2%, and the total mortality was 12.2%. The average poisoning age was (30.9 +/- 8.8) years old and the average death age was (30.6 +/- 12.0) years old. (2) There were 11 types of chemicals that caused these poisoning accidents, and most of the accidents were caused by benzene and homologs. (3) Most of the accidents occurred in manufacture, chemical industry, construction industry, transportation and storage industry, service and commerce. The risk was higher in some jobs than in others, such as paint spraying and cleanout. The poisoning accidents occurred more frequently from April to July each year. (4) The main causes of the accidents were poor ventilation (23.6%), lack of personal protection equipment (21.2%), lack of safety education (19.2%), and lack of safety work practice (15.8%) etc. The ventilation at the workplace involved in organic solvents should be maintained and the skin contacting directly with the organic solvents should be avoided, and it is encouraged to replace the poison with the nontoxic or lower toxic chemicals.

    Pinaki Dutta

    2015-01-01

    Full Text Available Background: Organophosphate compound (OPC poisoning is common in the developing countries such as India. The acute and later effects of OPC poisoning on pituitary and target gland hormones is largely unknown. Materials and Methods: This prospective study was conducted at Postgraduate Institute of Medical Education and Research between January 2012 and March 2013. Fourteen patients (8 males, age 18-50 years with acute OPC poisoning were included in the study based on the history and clinical features, documented decreased in plasma cholinesterase activity or presence of the OPC in gastric lavage/blood samples. The hormonal parameters were done at baseline, at the time of discharge and at three months of follow-up. Results: A total of 14 patients out of 46 with the mean age of 30.1 ± 10.3 years were finally eligible for the study. Hormonal alterations at admission were similar to sick euhormonal syndrome. Overall 7 of them had nine hormonal deficits at three months of follow up, 4 having sub normal basal cortisol level and two each had low testosterone and growth hormone and only one had thyroxine deficiency. Conclusion: Acute organophosphate poisoning results in endocrine dysfunction akin to sick euhormonal syndrome. However, in a small subset of patients, varying level of hormonal insufficiency may occur either at admission or later. These observations need re-validation in a larger group of patients with specific OPC.

    Full Text Available Objective: To investigate the prognostic value of the time-dependent changes of hematological parameters in patients with acute organophosphate poisoning. Methods: All patients admitted to emergency departments from 2010 through 2013 due to organophosphate poisoning were enrolled in the study. Demographic data, route of exposure, serum cholinesterase levels, complete blood count results of 5 consecutive days, mechanical ventilation requirement, length of stay in hospital, and outcomes were recorded. Results: Mechanically ventilated patients had higher leukocyte and neutrophil counts than nonventilated patients during the whole follow-up period, and both of them had a trend of decrease in both patient groups. There was no difference between patient groups in terms of lymphocyte counts at day 1, but mechanically ventilated patients had lower lymphocyte counts than nonventilated patients after day 2. Hemoglobin levels had a trend of decrease during the whole follow-up period in both patient groups. Conclusion: The parameters obtained from complete blood count can be used as sensitive follow-up parameters in patients with acute organophosphate poisoning by serial measurement.

    Because of the paucity of information on the epidemiology of acute poisoning requiring intensive medical care, all such patients treated on the medical intensive care unit of the university hospital in Frankfurt am Main, Germany, between January 1993 and December 1999, were retrospectively evaluated. Of the total of 6211 patients, 147 (80 women, 67 men, mean age 41 years, 2,3 %) were treated for acute intoxication in the intensive care unit. Reasons for admission to the intensive care unit were the need for ventilator treatment or intensive monitoring of vital functions. 52 % of the patients (n = 76) had attempted suicide, most of them using anti-depressive drugs (n = 19), paracetamol (n = 16), or benzodiazepines (n = 9). Two patients (2,6 %) died. 48 % of the patients (n = 71) were admitted because of accidental poisoning. Leading toxic agents in this group were heroin (n = 19), alcohol (n = 18) and digitalis (n = 12). 11 patients had taken herbicides, animal poisons or chemicals used at work or for house cleaning. In this cohort, three i. v. drug abusers (4,2 %) had died. Depending on the agents used, a variety of treatments (charcoal, antidots, extracorporal therapy) were undertaken. Due to excellent care in the prehospital phase and in the emergency room the number of patients requiring treatment on the intensive care unit was rather low. The mortality was in the range of other reports.

    Effects of neurophathologic changes and expression of Glu and 60 nNOS were observed in acute isocarbophos and phoxim poisoning in mice. KM male mice were randomly divided into three groups, which were control, non-treated and Huperzine A (HupA)-treated groups. The control group was given tween-80. Nontreated group was given isocarbophos (14.7 mg/kg) or phoxim (1702 mg/kg). HupA-treated group was given HupA 2h before phoxim or isocarbophos. Twenty-four hours after exposure, the whole brain was removed and adjacent coronal sections was obtained. One part of sections were stained with toluidine blue. The part of sections were used to assessed the expression of Glu and nNOS in the cortex and hippocampal of brain by immunohistochemistry. Compared to control group, non-treated group was observed nissal body nembers reduced and dyeing light. The animals of HupA protective group were observed nissal body nembers reduced, but the lesional degree was lighter obviously than non-treated group. The statistically reduced of the expression of Glu (PHupA-treated groups. Whereas for phoxim treatment, no changes were observed. HupA have protective effect against glutamatergic systems disorder caused by Isocarbophos poisoning. Administration of HupA have no effects of the neurotransmitter changes induces by acute poisoning of phoxim. It is different for the toxic effect mechanism of the two organophosphate.

    Psychiatry and psychology are beginning to recognize the importance of lead, mercury and heavy metals as causal partners in the development of mental disorders. Further, mental health researchers and clinicians are embracing the idea that the combined effects of genetics and environmental exposures can result in perturbations in brain neurochemistry leading to psychiatric disorders. The purpose of this review is to examine the biological foundations for the epidemiological observations previously identified by reviewing the toxicology literature and relating it to epidemiological studies addressing the role of poisoning with organophosphate pesticides (OPs) in neurobehavioral and neuropsychological disorders. The goal of this review is to raise awareness in the mental health community about the possibility that affective disorders might be the result of contributions from environmental and occupational pesticide poisoning.

    To evaluate the efficacy of the native flumazenil for acute self-poisoning with benzodiazepines. One hundred and twenty-six patients with unconsciousness from benzodiazepines-induced self-poisoning were randomly divided into two groups: flumazenil group(Group II, 63 cases) were treated with flumazenil, and conventional-medicine group(Group I, 63 cases) with placebo(glucose, vitamin C, KCl). A modified Glasgow Coma Scale(MGCS) and Observer's Assessment of Alertness/Sedation Scale(OAA/S) were used in the assessment of consciousness. MGCS were increased by 5.3, 8.0, 9.4 and 7.3 at 15 min, 30 min, 60 min and 180 min after intravenous flumazenil(P treatment. Flumazenil might improve benzodiazepines-induced unconsciousness markedly and may be the most effective antagonist of benzodiazepines.

    We experienced two cases of acute lead poisoning due to occupational exposure to lead. The patients were engaged in stripping off antirust compounds including Pb from a bridge and re-painting it at the same work place. Both patients exhibited colic, arthralgia, and anemia. Blood lead levels were 73.1 microg/dl and 96.3 microg/dl. Intravenous CaEDTA chelation therapy was therefore performed. After chelation, blood lead levels decreased and symptoms gradually disappeared. Although the patients were working with protective equipment, the workplace was in the mountains and there was no water for washing. The patients were thus unable to washing their hands and faces. We assume that they swallowed lead dust left on their hands and faces when they removed their clothing, and believe that this poisoning occurred due to lack of knowledge sufficient for protection.

    Glufosinate ammonium poisoning can cause neurological complications even after a symptom-free period. We prospectively investigated the predictors of neurologic complications in acute glufosinate ammonium poisoning and the change of serum ammonia level as a predictor of patient's presence and recovery of neurologic complication. This prospective observational study collected data from consecutive patients diagnosed with acute glufosinate ammonium poisoning between September 2014 and June 2016. Serum ammonia was serially measured. The patients were divided into two groups: the neurologic complication group and the nonneurologic complication group. We also defined 25 other insecticide- or herbicide-poisoned patients as controls. The neurologic complication group included 18 patients (72.0%). The latency period for neurologic complications was within 48-h postingestion. The peak ammonia level was statistically higher in the neurologic complication group than in the control group ( p glufosinate ammonium poisoning, serial serum ammonia level measurements are needed and a serum peak ammonia level greater than 90 μg/dL is a predictor of neurologic complications. Also, it is important to treat the hyperammonemia in acute glufosinate ammonium poisoning.

    Full Text Available We report a case of acute baclofen poisoning in a 23-year-old female patient, who committed suicide, which led to the development of a deep coma. The electroencephalogram on the first day recorded the phenomenon of “burst suppression”, which was seen as a sign of a dying brain. Subsequent studies have shown positive changes of the electroencephalogram and regression of neurological symptoms. Thus, the phenomenon of “burst suppression” in the depression of consciousness to deep coma and given adequate treatment, can be reversible.

    The non-destructive determination of mercury in human tissues after acute poisoning based on the use of a γ-ray spectometer with a Ge(Li) semiconductor detector is described. Samples were irradiated at a thermal neutron flux density of about 10 12 n cm -2 s -1 for 4 hrs. From the results of the preliminary experiments the following conclusions have been drawn. The mercury losses should be negligible when drying of the biological samples at 80 deg C. To irradiate samples for mercury determination is preferable in silica tubes than in polyethylene ones.

    Rhabdomyolysis is most frequently caused by soft tissue injury with trauma to the extremities. Non-traumatic rhabdomyolysis may be caused by alcohol or drug abuse, infection, collagen disease, or intensive exercise, but incidence is low. In particular, rhabdomyolysis resulting from carbon monoxide poisoning is especially rare. If caught before death, carbon monoxide poisoning has been shown to cause severe muscle necrosis and severe muscle damage leading to acute renal failure. In cases of carbon-monoxide-induced rhabdomyolsis leading to acute compartment syndrome in the buttocks and sciatic nerve injury are rare. We have experience treating patients with acute compartment syndrome due to rhabdomyolysis following carbon monoxide poisoning. We report the characteristic features of muscle necrosis observed during a decompression operation and magnetic resonance imaging findings with a one-year follow-up in addition to a review of the literature.

    The incidence and clinical aspects of seizures remain to be elucidated in patients with acute pesticide intoxication. The present study included subjects who ingested pesticide with the intention of committing suicide and were treated at Soonchunhyang University Hospital (Cheonan, Korea) between January 2011 and December 2014. We analyzed the incidence and characterized the type and frequency of seizure, from the medical records of 464 patients with acute pesticide intoxication, according to the pesticide class. The effect of seizure on the clinical outcome was assessed. The incidence of seizure was 31.5% in patients who ingested glufosinate ammonium {2-amino-4-[hydroxyl (methyl) phosphinoyl] butyrate; ammonium DL-homoalanin-4-yl (methyl) phosphinate}, followed by those who ingested pyrethroid (5.9%) or glycine derivatives (5.4%). All of the seizures developed between 12 and 24 h of pesticide ingestion and had ceased by 72 h after seizure initiation, following treatment with antiseizure medication. Generalized tonic-clonic seizures were the most commonly observed (85.7% of the cases). Multivariable logistic regression analysis showed that the effect of seizure on mortality was not statistically significant. In conclusion, glufosinate ammonium herbicide is the most common seizurogenic pesticide class. Seizure itself was not a risk factor for mortality in patients with acute glufosinate ammonium intoxication.

    Brain temperature (BT) is associated with the balance between cerebral blood flow and metabolism according to the ''heat-removal'' theory. The present study investigated whether BT is abnormally altered in acute and subacute CO-poisoned patients by using {sup 1}H-magnetic resonance spectroscopy (MRS). Eight adult CO-poisoned patients underwent 3-T magnetic resonance imaging in the acute and subacute phases after CO exposure. MRS was performed on deep cerebral white matter in the centrum semiovale, and MRS-based BT was estimated by the chemical shift difference between water and the N-acetyl aspartate signal. We defined the mean BT + 1.96 standard deviations of the BT in 15 healthy controls as the cutoff value for abnormal BT increases (p < 0.05) in CO-poisoned patients. BT of CO-poisoned patients in both the acute and subacute phases was significantly higher than that of the healthy control group. However, BT in the subacute phase was significantly lower than in the acute phase. On the other hand, no significant difference in body temperature was observed between acute and subacute CO-poisoned patients. BT weakly correlated with body temperature, but this correlation was not statistically significant (rho = 0.304, p = 0.2909). The present results suggest that BT in CO-poisoned patients is abnormally high in the acute phase and remains abnormal in the subacute phase. BT alteration in these patients may be associated with brain perfusion and metabolism rather than other factors such as systemic inflammation and body temperature. (orig.)

    Ciguatoxins (CTXs) cause long-term disturbance of cerebral functions. The primary mechanism of neurotoxicity is related to their interaction with voltage-gated sodium channels. However, until now, the neurological targets for CTXs in the brain of intact animals have not been described. In our study, 1 day following oral exposure to 0.26 ng/g of Pacific ciguatoxin 1 (P-CTX-1), we performed in vivo electrophysiological recordings in the rat anterior cingulate cortex (ACC) and identified the increase in spontaneous firings and enhanced responses to visceral noxious stimulation. Local field recordings characterized the P-CTX-1-induced synaptic potentiation and blockage of the induction of electrical stimulation-induced long-term potentiation in the medial thalamus (MT)-ACC pathway. Furthermore, intracerebroventricular administration of P-CTX-1 at doses of 1.0, 5.0, and 10 nM produced a dose-dependent increase in ACC neuronal firings and MT-ACC synaptic transmission. Further studies showed upregulated Na(+) channel expression in astrocytes under pathological conditions. We hypothesized that the astrocytes might have been activated in the ciguatera poisoning in vivo. Increases in glial fibrillary acid protein expression were detected in reactive astrocytes in the rat ACC. The activation of astroglia was further indicated by activation of the gap junction protein connexin 43 and upregulation of excitatory amino acid transporter 2 expression suggesting that glutamate was normally rapidly cleared from the synaptic cleft during acute ciguatera poisoning. However, neurotoxicity and reactive astrogliosis were not detected in the ACC after 7 days of P-CTX-1 exposure. The present results are the first characterization of P-CTX-1-invoked brain cortex neuronal excitotoxicity in vivo and supported the theme that neuron and astroglia signals might play roles in acute ciguatera poisoning.

    To explore the clinical efficacy of early application of sequential gastrointestinal lavage in patients with acute paraquat poisoning by analyzing the clinical data of 97 patients. A total of 97 eligible patients with acute paraquat poisoning were divided into conventional treatment group (n = 48) and sequential treatment group (n = 49). The conventional treatment group received routine gastric lavage with water. Then 30 g of montmorillonite powder, 30 g of activated charcoal, and mannitol were given to remove intestinal toxins once a day for five days. The sequential treatment group received 60 g of montmorillonite powder for oral administration, followed by small-volume low-pressure manual gastric lavage with 2.5%bicarbonate liquid. Then 30 g of activated charcoal, 30 g of montmorillonite powder, and polyethylene glycol electrolyte lavage solution were given one after another for gastrointestinal lavage once a day for five days. Both groups received large doses of corticosteroids, blood perfusion, and anti-oxidation treatment. The levels of serum potassium, serum amylase (AMY) alanine aminotransferase (ALT), total bilirubin (TBIL), blood urea nitrogen (BUN), creatinine (Cr), lactate (Lac), and PaO₂of patients were determined at 1, 3, 5, 7, and 10 days. Laxative time, mortality, and survival time of dead cases were evaluated in the two groups. The incidence rates of hypokalemia (110 U/L) were significantly lower in the sequential treatment group than in the conventional treatment group (P 80 U/L), TBIL (>34.2 µmol/L), BUN (>7.2 mmol/L), and Cr (>177 µmol/L) between the two groups (P>0.05). However, the highest levels of ALT, TBIL, BUN, Cr, and Lac were significantly lower in the sequential treatment group than in the conventional treatment group (P treatment group had significantly lower incidence of PaO₂(treatment group (P poisoning.

  8. Role of biomarkers of nephrotoxic acute kidney injury in deliberate poisoning and envenomation in less developed countries.

    Mohamed, Fahim; Endre, Zoltan H; Buckley, Nicholas A

    2015-07-01

    Acute kidney injury (AKI) has diverse causes and is associated with increased mortality and morbidity. In less developed countries (LDC), nephrotoxic AKI (ToxAKI) is common and mainly due to deliberate ingestion of nephrotoxic pesticides, toxic plants or to snake envenomation. ToxAKI shares some pathophysiological pathways with the much more intensively studied ischaemic AKI, but in contrast to ischaemic AKI, most victims are young, previously healthy adults. Diagnosis of AKI is currently based on a rise in serum creatinine. However this may delay diagnosis because of the kinetics of creatinine. Baseline creatinine values are also rarely available in LDC. Novel renal injury biomarkers offer a way forward because they usually increase more rapidly in AKI and are normally regarded as absent or very low in concentration, thereby reducing the need for a baseline estimate. This should increase sensitivity and speed of diagnosis. Specificity should also be increased for urine biomarkers since many originate from the renal tubular epithelium. Earlier diagnosis of ToxAKI should allow earlier initiation of appropriate therapy. However, translation of novel biomarkers of ToxAKI into clinical practice requires better understanding of non-renal factors in poisoning that alter biomarkers and the influence of dose of nephrotoxin on biomarker performance. Further issues are establishing LDC population-based normal ranges and assessing sampling and analytical parameters for low resource settings. The potential role of renal biomarkers in exploring ToxAKI aetiologies for chronic kidney disease of unknown origin (CKDu) is a high research priority in LDC. Therefore, developing more sensitive biomarkers for early diagnosis of nephrotoxicity is a critical step to making progress against AKI and CKDu in the developing world. © 2015 The British Pharmacological Society.

    Mass or cluster methanol poisonings are frequently reported from around the world. The comparative effectiveness of ethanol and fomepizole as antidotes for methanol poisoning is unknown due to the difficulty of performing a randomized controlled trial. During an outbreak of mass poisonings in the Czech Republic in 2012-2014, we compared the effects of antidotes on the frequency of health sequelae and mortality. The study was designed as a cross-sectional case series and quasi-case-control study. Patients with a diagnosis of methanol poisoning on admission to hospitals were identified for the study. Diagnosis was established when (i) a history of recent ingestion of illicit spirits was available and serum methanol was higher than 6.2 mmol/L (20 mg/dL), or (ii) there was a history/clinical suspicion of methanol poisoning, and serum methanol was above the limit of detection with at least two of the following: pH poisoning and other key parameters, was selected. Data were obtained from 100 hospitalized patients with confirmed poisoning: 25 patients treated with fomepizole were compared with 68 patients receiving ethanol (seven patients did not receive any antidote). More severely acidotic (p 12 h; p = 0.028) patients received fomepizole more often than ethanol, as reflected in the higher number of fomepizole-treated patients being intubated (p = 0.009). No association was found between the type of antidote and the survival in either the case series (p = 0.205) or the quasi-control groups (p = 0.705) in which patients were very closely matched to minimize confounding by allocation. In the multivariate analysis, positive serum ethanol (odds ratio [OR], 10.8; 95% confidence interval [CI], 2.9-39.9) and arterial blood pH (OR, 3.7; 95% CI, 1.3-10.5) on admission were the only independent variables for the survival. The median intensive care unit length of stay was 6 (range, 2-22) days in the fomepizole group and 4 (range, 1-33) days in the ethanol group (p = 0.131). There

    The duration of hemodialysis (HD) sessions for the treatment of acute ethylene glycol poisoning is dependent on concentration, the operational parameters used during HD, and the presence and severity of metabolic acidosis. Ethylene glycol assays are not readily available, potentially leading to undue extension or premature termination of HD. We report a prediction model for the duration of high-efficiency HD sessions based retrospectively on a cohort study of 26 cases of acute ethylene glycol poisoning in 24 individuals treated by alcohol dehydrogenase competitive inhibitors, cofactors and HD. Two patients required HD for more than 14 days, and two died. In 19 cases, the mean ethylene glycol elimination half-life during high-efficiency HD was 165 minutes (95% confidence interval of 151-180 minutes). In a training set of 12 patients with acute ethylene glycol poisoning, using the 90th percentile half-life (195 minutes) and a target ethylene glycol concentration of 2 mmol/l (12.4 mg/dl) allowed all cases to reach a safe ethylene glycol under 3 mmol/l (18.6 mg/dl). The prediction model was then validated in a set of seven acute ethylene glycol poisonings. Thus, the HD session time in hours can be estimated using 4.7 x (Ln [the initial ethylene glycol concentration (mmol/l)/2]), provided that metabolic acidosis is corrected.

    1,2,3-Trichloropropane is widely used in industrial and agricultural production. However 1,2,3-trichloropropane poisoning has been rarely encountered in clinical practices. Here, a 45-year-old farmer who suffered fulminant hepatic failure due to ingestion of 1,2,3-trichloropropane has been reported and literature about 1,2,3-trichloropane poisoning has been reviewed. For this case, reduced glutathione, vitamin K, pantoprazole were infused intravenously, and transfusion of blood plasma, platelets and red blood cells were carried out. Unfortunately, the patient's family gave up treatment and they left the hospital with the patient because of the low chance of recovery 20 hr after admission. Based on blood toxicology screening, patient history and rapid deterioration of the patient, the cause of fulminant hepatic failure was determined to be acute intoxication of 1,2,3-trichloropropane by unintentional toxicity. 1,2,3-trichloropropane has histopathological toxic effects on many organs and this toxic effect occurs within a short period after ingestion, with liver as the major affected organ. © 2010 The Author.

    2014-11-01

    Full Text Available Background: This toxicological investigation involves a report on the death of four occupants of a sport utility vehicle on one of the major busy Federal roads of Nigeria where they were held for up to three hours in a traffic jam while the car was steaming. Methods: Autopsy was executed using the standard procedure and toxicological analysis was done using simple spectrophotometric method to establish the level of carboxyhaemoglobin (HbCO in peripheral blood in the four occupants. Results: The autopsy report indicated generalized cyanosis, sub-conjuctival hemorrhages, marked laryngo-trachea edema with severe hyperemia with frothy fluid discharges characteristic of carbon monoxide poisoning. Toxicological report of the level of HbCO in part per million (ppm in the peripheral blood of the four occupants was A= 650 ppm; B= 500 ppm; C= 480 ppm, and D= 495 ppm against the maximum permissible level of 50 ppm. Conclusion: The sudden death of the four occupants was due to excessive inhalation of the carbon monoxide gas from the exhaust fumes leaking into the cabin of the car. The poor road network, numerous potholes, and traffic jam in most of roads in Nigeria could have exacerbated a leaky exhaust of the smoky second hand SUV car leading to the acute carbon monoxide poisoning.

  13. Paraquat poisoning: an experimental model of dose-dependent acute lung injury due to surfactant dysfunction

    1998-03-01

    Full Text Available Since the most characteristic feature of paraquat poisoning is lung damage, a prospective controlled study was performed on excised rat lungs in order to estimate the intensity of lesion after different doses. Twenty-five male, 2-3-month-old non-SPF Wistar rats, divided into 5 groups, received paraquat dichloride in a single intraperitoneal injection (0, 1, 5, 25, or 50 mg/kg body weight 24 h before the experiment. Static pressure-volume (PV curves were performed in air- and saline-filled lungs; an estimator of surface tension and tissue works was computed by integrating the area of both curves and reported as work/ml of volume displacement. Paraquat induced a dose-dependent increase of inspiratory surface tension work that reached a significant two-fold order of magnitude for 25 and 50 mg/kg body weight (P<0.05, ANOVA, sparing lung tissue. This kind of lesion was probably due to functional abnormalities of the surfactant system, as was shown by the increase in the hysteresis of the paraquat groups at the highest doses. Hence, paraquat poisoning provides a suitable model of acute lung injury with alveolar instability that can be easily used in experimental protocols of mechanical ventilation

    2015-06-01

    Full Text Available Background: Pyrethroids are generally of low toxicity to humans, but in suicidal poisonings which are usually associated with ingestion of high doses, they lead to severe systemic effects. Case Report: A 30-year old woman presented to emergency department with a history of intentional ingestion of about 15 mL of prallethrin around 3 days earlier. She complained of shortness of breath along with chest pain for the last 2 days. She reported no vomiting or stomach pain prior to presentation to hospital. On chest auscultation, breath sounds were mildly decreased in bilateral infrascapular areas with generalized crepitation. Arterial blood gas analysis revealed respiratory alkalosis. Chest X ray and computed tomography of thorax revealed widespread confluent areas of consolidation with interlobular septal thickening involving bilateral parahilar regions suggestive of acute respiratory distress syndrome (ARDS. The patient did not respond to broad spectrum antibiotic coverage, diuretics and oxygen inhalation. Intravenous methylprednisolone (2 mg/kg/day divided 6 hourly was started and slowly tapered off during the next days. The patient discharged after 3 weeks in good health. Discussion: As pyrethroids can affect sodium channels, the osmotic gradient of alveolar epithelium probably disrupts and therefore, alveolar infiltrations gradually spread over lungs. In addition, there is a possibility of hypersensitivity reactions to pyrethroids, which can cause progressive inflammation and involve respiratory tract in severe cases. Conclusion: Pyrethroid poisoning can lead to ARDS. Steroid therapy may help such patients tide over the pulmonary crisis.

    The 2 antidotes for acute cyanide poisoning in the United States must be administered by intravenous injection. In the out-of-hospital setting, intravenous injection is not practical, particularly for mass casualties, and intramuscular injection would be preferred. The purpose of this study is to determine whether sodium nitrite and sodium thiosulfate are effective cyanide antidotes when administered by intramuscular injection. We used a randomized, nonblinded, parallel-group study design in 3 mammalian models: cyanide gas inhalation in mice, with treatment postexposure; intravenous sodium cyanide infusion in rabbits, with severe hypotension as the trigger for treatment; and intravenous potassium cyanide infusion in pigs, with apnea as the trigger for treatment. The drugs were administered by intramuscular injection, and all 3 models were lethal in the absence of therapy. We found that sodium nitrite and sodium thiosulfate individually rescued 100% of the mice, and that the combination of the 2 drugs rescued 73% of the rabbits and 80% of the pigs. In all 3 species, survival in treated animals was significantly better than in control animals (log rank test, Pcyanide poisoning in 3 clinically relevant animal models of out-of-hospital emergency care.

    Cerebral computed tomography (CT) findings were described in twenty-six cases with the late sequelae of acute carbon monoxide poisoning and were computed with the neurological symptoms and signs. The CT findings include symmetrical periventricular white matter low density in five cases, globes pallidus low density in six cases, ventricular dilatation in seven cases, ventricular dilatation and sulci widening in three cases, and normal findings in ten cases. Only one case showed low densities in both periventricular white matter and globes pallidus. Late sequelae of the interval from of carbon monoxide poisoning were clinically categorized as cortical dysfunction, parkinsonian feature, and cerebella dysfunction. The severity of the clinical symptoms and signs of neurological sequelae is generally correlated with presence and multiplicity of abnormal brain CT findings. But of fourteen cases showing the parkinsonian feature, only five cases had low density of globes pallidus in brain CT. Another case showing small unilateral low density of globes pallidus had no parkinsonian feature but showed mild cortical dysfunction.

    Visual disturbances due to the toxic effect of formic acid in acute methanol poisonings are generally transient. The subjective symptoms of visual toxicity may resolve within few weeks and fundoscopic signs of acute optic neuropathy subside within 1-2 months; therefore, the prevalence of long-term visual sequelae in the population of survivors of poisonings may be underestimated. To study the prevalence and character of long-term visual sequelae of acute methanol poisonings based on the data from the Czech mass methanol outbreak in 2012. A total of 50 patients with confirmed methanol poisoning were included in this longitudinal cross-sectional study, median age: 48 (range, 23-73) years. The following tests were performed: optical coherence tomography or OCT with evaluation of the retinal nerve fibers layer (RNFL), visual evoked potentials (VEP), magnetic resonance imaging (MRI) of brain, complete ocular examination (visual acuity/field, color vision, contrast sensitivity, and fundus), neurological examinations, and biochemical tests. Of 50 patients, 7/50 (14%) were discharged with diagnosed visual sequelae and 6/50 (12%) were discharged with both visual and central nervous system sequelae of poisoning. On the follow-up examination, 20/50 (40%) of the patients had long-term visual sequelae, with 8% of blindness. A total of 38% of the patients had abnormal (28% borderline) findings on RNFL, and 40% had abnormal (18% borderline) VEP. Among the patients discharged without detected visual sequelae, 8/37 (22%) had abnormal RNFL and VEP. Patients with visual sequelae had brain lesions more often (70% vs. 27%, p methanol, ethanol, HCO3-, formate, pH, anion gap, and base deficit (all p methanol poisonings in general.

    The mechanism underlying delayed neuropsychological sequelae (DNS) after acute carbon monoxide (CO) poisoning is unclear. There are no effective treatments for DNS. As part of a new generation of antioxidants, edaravone has been reported to improve clinical outcomes in patients exhibiting ischemic strokes. There has been little data about edaravone in relationship to DNS prevention and treatment. We hypothesized that edaravone could ameliorate DNS: Here we test that hypothesis in rabbits Rabbits were randomly divided into sham control,DNS group, saline group and edaravone group. DNS model was made by intraperitoneal injection of CO. Normal saline or edaravone (1 mg/kg, twice daily, a total of one course for 14 days) was infused through the ear vein from Day 15 since the DNS model was established. Serum superoxide dismutase (SOD) activity and malondialdehyde (MDA) were measured in each group. Magnetic resonance spectroscopy (MRS) was used to examine regions of the brain for various compounds. The apoptotic index and neuronal density in the hippocampal CA1 area were also investigated. SOD activity decreased significantly and MDA content increased substantially in the DNS group and saline group when compared with the sham control (p edaravone group, serum SOD activity significantly increased and MDA levels significantly decreased when compared with DNS and saline group (p edaravone group (p edaravone group was significantly lower than that of the DNS and saline groups (p edaravone group was significantly higher than that of the DNS and saline group in the hippocampal CA1 area (p edaravone could ameliorate DNS after acute carbon monoxide poisoning in rabbits. These results suggest free radicals could be involved in the underlying mechanisms of DNS. Furthermore, brain MRS shows promise as a tool for early diagnosis for DNS.

    Data about etiologic and demographic characteristics of acute poisoning in adults in Qatar are lacking. This prospective observational study was undertaken to analyze characteristics and possible determinants of acute poisoning in adults in Qatar. During 2010, 18,073 patients attended the emergency department of Hamad General Hospital, a teaching hospital in Qatar. Out of them, 599 (3.3%) patients were diagnosed as "poisoning case" with either chemical or pharmaceutical substances. The prevalence rate of poisoning incidence was 35.3/100,000 population. Seven patients died, corresponding with a case-fatality rate of 0.39/1000. The majority were male (65%) and the mean age was 34 years. The poisons involved were mainly chemicals (61.6%) and pharmaceuticals (38.4%). Female, mainly single, suffered more intentional poisoning compared to male. Of the patients aged 60 years and above (7.2%), the majority (95.3%) suffered unintentional poisoning with pharmaceuticals; 56% with warfarin, 12% with digoxin and 7% with insulin. Multivariate analysis shows that female gender, single status, younger than 35 years of age, being poisoned by pharmaceutical products, and the need for hospitalization are significant determinants for acute intentional poisoning after adjusting all other possible covariates. The findings of this study can be used to establish awareness and prophylactic campaigns in Qatar.

    To elucidate the altered gene network in the brains of carbon monoxide (CO) poisoned rats after treatment with hyperbaric oxygen (HBO₂). RNA sequencing (RNA-seq) analysis was performed to examine differentially expressed genes (DEGs) in brain tissue samples from nine male rats: a normal control group; a CO poisoning group; and an HBO₂ treatment group (three rats/group). Reverse transcription polymerase chain reaction (RT-PCR) and real-time quantitative PCR were used for validation of the DEGs in another 18 male rats (six rats/group). RNA-seq revealed that two genes were upregulated (4.18 and 8.76 log to the base 2 fold change) (p⟨0.05) in the CO-poisoned rats relative to the control rats; two genes were upregulated (3.88 and 7.69 log to the base 2 fold change); and 23 genes were downregulated (3.49-15.12 log to the base 2 fold change) (p⟨0.05) in the brains of the HBO₂-treated rats relative to the CO-poisoned rats. Target prediction of DEGs by gene network analysis and analysis of pathways affected suggested that regulation of gene expressions of dopamine metabolism and nitric oxide (NO) synthesis were significantly affected by CO poisoning and HBO₂ treatment. Results of RT-PCR and real-time quantitative PCR indicated that four genes (Pomc, GH-1, Pr1 and Fshβ) associated with hormone secretion in the hypothalamic-pituitary system have potential as markers for prognosis of CO. This study is the first RNA-seq analysis profile of HBO₂ treatment on rats with acute CO poisoning. It concludes that changes of hormone secretion in the hypothalamic-pituitary system, dopamine metabolism and NO synthesis involved in brain damage and behavior abnormalities after CO poisoning and HBO₂ therapy may regulate these changes.

    Objective: To discuss the clinical and imaging characteristics of delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods: The clinical data of 14 patients with DEACMP were respectively analyzed. Results: Initial symptom included mentally falling (MMSE rate < 20 points) in 14 patients (100%), incontinence of urine in 11 patients (78%). Relatively significant increase of hematoma (HCT) (average level 0.503±0.027) was found in 6 patients. Three kinds of brain magnetic resonance imaging (MRI) appearance including diffuse white matter lesion, cortical lesion and basal nuclei lesion often existed in association. Therapy for improving circulation was given in 14 patients, and therapy with hormone was given in 9 patients; with 85% improvement rate. 5 patients without hormone therapy but with improving circulation therapy also received improvement. Conclusion: High level of HCT might be one of the causes of DECACMP due to acute disturbance of brain micro-circulation.. Close monitoring the change of HCT levels should be adopted for at least 3-6 months during therapy. Therapy for improving circulation and for anti-agglutination of platelets should be performed besides the routine high-tension oxygen therapy. Low FA value on DTI indicates the occurrence of a demyelization change in the brain long tract fibers, which indicated therapeutic effect of hormone treatment. And, therefore it would be better to perform DTI scan before therapy for individualized therapy. (authors)

    Full Text Available Intermediate syndrome (IMS is a major cause of death from respiratory failure following acute organophosphate poisoning. The objective of this study was to determine repetitive nerve stimulation (RNS predictors of IMS that would assist in patient management and clinical research.Seventy-eight consenting symptomatic patients with organophosphate poisoning were assessed prospectively with daily physical examination and RNS. RNS was done on the right and left median and ulnar nerves at 1, 3, 10, 15, 20, and 30 Hz. The study was conducted as a prospective observational cohort study in the Central Province, Sri Lanka. IMS was diagnosed in ten out of 78 patients using a priori clinical diagnostic criteria, and five of them developed respiratory failure. All ten patients showed progressive RNS changes correlating with the severity of IMS. A decrement-increment was observed at intermediate and high frequencies preceding the onset of clinical signs of IMS. As the patient developed clinical signs of IMS, decrement-increment was progressively noted at low and intermediate frequencies and a combination of decrement-increment and repetitive fade or severe decrement was noted at high frequencies. Severe decrement preceded respiratory failure in four patients. Thirty patients developed forme fruste IMS with less severe weakness not progressing to respiratory failure whose RNS was characterized by decrement-increment or a combination of decrement-increment and repetitive fade but never severe decrements.Characteristic changes in RNS, preceding the development of IMS, help to identify a subgroup of patients at high risk of developing respiratory failure. The forme fruste IMS with the characteristic early changes on RNS indicates that IMS is a spectrum disorder. RNS changes are objective and precede the diagnosis and complications of IMS. Thus they may be useful in clinical management and research.

    The methods of light microscopy, immunohistochemistry, and electron microscopy were employed to study the morphofunctional changes in epithelium of bronchial and respiratory segments of the rat lungs used as models of acute fatal poisoning with household gas. It was shown that this toxic effect induces the pathological process involving all the elements of the epithelial layer in the bronchial and respiratory segments of the lungs of experimental animals. At the ultrastructural level, mitochondria and endoplasmic reticulum structures are affected, with the death of epithelial cells leading to the damage of the aerohematic barrier. The toxic effect of the gaseous mixture on the membranes causes the destruction of various elements of the epithelial layer. The results of this study help to understand the mechanisms of death in the case of acute fatal poisoning with household gas.

    To analyze the impact of quality-indicator-based measures for improving quality of care for acute poisoning in pediatric emergency departments. Recent assessments of quality indicators were compared with benchmark targets and with results from previous studies. The first study evaluated 6 basic indicators in the pediatric emergency departments of members of to the working group on poisoning of the Spanish Society of Pediatric Emergency Medicine (GTI-SEUP). The second study evaluated 20 indicators in a single emergency department of GTI-SEUP members. Based on the results of those studies, the departments implemented the following corrective measures: creation of a team for gastric lavage follow-up, preparation of a new GTI-SEUP manual on poisoning, implementation of a protocol for poisoning incidents, and creation of specific poisoning-related fields for computerized patient records. The benchmark targets were reached on 4 quality indicators in the first study. Improvements were seen in the availability of protocols, as indicators exceeded the target in all the pediatric emergency departments (vs 29.2% of the departments in an earlier study, P < .001). No other significant improvements were observed. In the second study the benchmarks were reached on 13 indicators. Improvements were seen in compliance with incident reporting to the police (recently, 44.4% vs 19.2% previously, P = .036), case registration in the minimum basic data set (51.0% vs 1.9%, P < .001), and a trend toward increased administration of activated carbon within 2 hours (93.1% vs 83.5%, P = .099). No other significant improvements were seen. The corrective measures led to improvements in some quality indicators. There is still room for improvement in these emergency departamens' care of pediatric poisoning.

    Agricultural pesticide use in Viet Nam has more than tripled since 1990. However, pesticide legislation and regulations have not been developed in response to this large increase in usage, as a result of which pesticides pose a serious threat to human health and the environment. This paper identifies the need to improve pesticide regulations in Viet Nam through a comparative analysis of pesticide regulations in Viet Nam and the United States of America, where the rate of acute poisoning among agricultural workers is much lower than in Viet Nam and where information pertaining to pesticide regulations is made accessible to the public. The analysis identified several measures that would help to improve Viet Nam's pesticide regulations. These include enhancing pesticide legislation, clarifying the specific roles and active involvement of both the environmental and health sectors; performing a comprehensive risk-benefit evaluation of pesticide registration and management practices; improving regulations on pesticide suspension and cancellation, transport, storage and disposal; developing import and export policies and enhancing pesticide-related occupational safety programmes.

    A previously healthy 2-year-old girl was admitted with generalized convulsive status epilepticus. She was in a stupor and could respond only to painful stimuli. She also had severe metabolic acidosis. Although initial liver function tests were normal, they were found to be moderately high on the fifth day of admission; however, they dropped to their normal ranges on the twelfth day of admission. Initially, the patient was diagnosed as having idiopathic status epilepticus, and classic anticonvulsant agents, including diazepam, phenytoin, and then phenobarbital, were given. However, her seizures did not subside, and diazepam infusion was initiated. After initiation of diazepam infusion, the seizures were completely controlled. On the fourth day of admission, her parents said that she had accidentally received 20 tablets (a total dose of 2000 mg) of isoniazid just before admission to our hospital. Later, we injected 200 mg of pyridoxine intravenously. During follow-up, her general condition improved, and anticonvulsant agents were discontinued because an electroencephalogram was found to be norma. She was discharged from the hospital on the twelfth day of admission. At the fourth month of follow-up, she was seizure free. Because of this case, we would like to re-emphasize that acute isoniazid poisoning should also be considered in a child with unexplained status epilepticus.

    We describe a case of an acute lethal poisoning with hydrocarbons resulting from massive accidental inhalation of gasoline vapors. The victim, a 50-year-old man was found unconscious inside a control room for the transport of unleaded fuel. Complete autopsy was performed and showed evidence of congestion and edema of the lungs. Toxicological investigation was therefore fundamental to confirm exposure to fumes of gasoline. Both venous and arterial blood showed high values of volatiles in particular for benzene (39.0 and 30.4 μg/mL, respectively), toluene (23.7 and 20.4 μg/mL), and xylene isomers (29.8 and 19.3 μg/mL). The relatively low values found in the lungs are consistent with the fact that the subject, during the rescue, underwent orotracheal intubation followed by resuscitation techniques, while the low concentrations for all substances found in urine and kidneys could point to a death that occurred in a very short time after first contact with the fumes of gasoline. © 2012 American Academy of Forensic Sciences.

    The long-term mortality after prehospital treatment for acute poisoning has not been studied previously. Thus, we aimed to estimate the five-year mortality and examine the causes of death and predictors of death for all acutely poisoned patients treated in ambulances, the emergency outpatient clinic, and hospitals in Oslo during 2003-2004. A prospective cohort study included all adults (≥16 years; n=2045, median age=35 years, male=58%) who were discharged after treatment for acute poisoning in ambulances, the emergency outpatient clinic, and the four hospitals in Oslo during one year. The patients were observed until the end of 2008. Standardized mortality rates (SMRs) were calculated and multivariate Cox regression analysis was applied. The study comprised 2045 patients; 686 treated in ambulances, 646 treated in the outpatient clinic, and 713 treated in hospitals. After five years, 285 (14%) patients had died (four within one week). The SMRs after ambulance, outpatient, and hospital treatment were 12 (CI 9-14), 10 (CI 8-12), and 6 (CI 5-7), respectively. The overall SMR was 9 (CI 8-10), while the SMR after opioid poisoning was 27 (CI 21-32). The most frequent cause of death was accidents (38%). In the regression analysis, opioids as the main toxic agents (HR 2.3, CI 1.6-3.0), older age (HR 1.6, CI 1.5-1.7), and male sex (HR 1.4, CI 1.1-1.9) predicted death, whereas the treatment level did not predict death. The patients had high mortality compared with the general population. Those treated in hospital had the lowest mortality. Opioids were the major predictor of death.

    Full Text Available Background: The biological behaviour and clinical significance of mercury toxicity vary according to its chemical structure. Mercury differs in its degree of toxicity and in its effects on the nervous, digestive and immune systems as well as on organs such as the lungs, kidneys, skin, eyes and heart. Human exposure occurs mainly through inhalation of elemental mercury vapours during industrial and artisanal processes such as artisanal and small-scale gold mining. Case presentation: A 52-years-old female, housewife, with a body mass index of 25.3 kg/cm2, without smoking or alcohol habits or any important clinical or chronic cardiovascular history, was admitted to the emergency room due to probable accidental poisoning by butane gas. Clinical manifestations with a headache, dizziness, cough, and dyspnoea of medium to small efforts. An initial physical exploration with Glasgow scored at 15, with arrhythmic heart sounds, pulmonary fields with bilateral subcrepitant rales and right basal predominance. Electrocardiographic findings were as follows: a cardiac frequency of 50 beats per minute and atrioventricular dissociation. Laboratory parameters were: white blood cells at 15.8 × 109/L; aspartate aminotransferase at 38 U/L; lactate dehydrogenase at 1288 U/L; creatine-kinase at 115 U/L; CK-MB fraction at 28 U/L; and other biochemical parameters were within the reference values. A radiographic evaluation showed flow cephalization, diffuse bilateral infiltrates with right basal predominance. In addition, the patient presented data of low secondary expenditure to third-degree atrioventricular (AV block for which the placement of a transvenous pacemaker was decided, substantially improving the haemodynamic parameters. Subsequently, after a family interrogation, the diagnosis of mercury inhalation poisoning was established. An initial detection of mercury concentration (Hg(0 was carried out, reporting 243.5 µg/L. In view of this new evidence, mercury

    2017-01-01

    Lithium is a commonly prescribed treatment for bipolar affective disorder. However, treatment is complicated by lithium's narrow therapeutic index and the influence of kidney function, both of which increase the risk of toxicity. Therefore, careful attention to dosing, monitoring, and titration...... is required. The cause of lithium poisoning influences treatment and 3 patterns are described: acute, acute-on-chronic, and chronic. Chronic poisoning is the most common etiology, is usually unintentional, and results from lithium intake exceeding elimination. This is most commonly due to impaired kidney...... function caused by volume depletion from lithium-induced nephrogenic diabetes insipidus or intercurrent illnesses and is also drug-induced. Lithium poisoning can affect multiple organs; however, the primary site of toxicity is the central nervous system and clinical manifestations vary from asymptomatic...

    Five cases of acute accidental poisoning with White Hellebore are reported. All cases occurred several minutes after the ingestion of home-made gentian wine. The clinical signs were nausea, vomiting, abdominal pain, hypotension and bradycardia. The initial ECG showed sinus bradycardia in 4 cases. In one patient, complete atrioventricular block with an ectopic atrial bradycardia and an intermittent idioventricular rhythm was recorded. Symptomatic treatment and/or atropine led to recovery within a few hours. These symptoms suggested poisoning with a veratrum alkaloid. The White Hellebore (Veratrum Album L.) and the Yellow Gentian (Gentiana Lutea L.) often grow side by side in the fields; it is easy to confuse the two plants before they flower if one is not a botanist. Each gentian wine was analysed by thin layer chromatography and chemical ionisation spectrometry. All the wines contained Veratrum alkaloids.

    Objectives Changes in poisoning trends may affect both complications and outcomes in patients with acute poisoning. This study reports the treatments given and the frequency of complications, also related to treatment, mortality and sequelae related to various toxic agents. Methods All acute poisonings in adults (≥16 years) admitted to the five hospitals in Oslo were included consecutively during one year (2008 to 2009) in an observational cross-sectional multicenter study. A standardized form was completed by the treating physician, which covered the study aims. Results There were 1065 admissions in 912 patients. The median length of hospital stay was one day, and 49% were observed in an intensive care unit (ICU). Active treatment was given to 83%, and consisted of supportive therapy (70%), antidote(s) (38%), activated charcoal (16%) and gastric lavage (9%). The most commonly used antidotes were flumazenil (19%), naloxone (17%) and N-acetylcysteine (11%). The rate of treatment-related complications was 2.4% (21/884). Neither flumazenil, naloxone, nor the combination, was associated with convulsions or other complications. Among those receiving N-acetylcysteine, 5% (6/120) developed allergic reactions, one of which mandated discontinuation of treatment. Nineteen percent presented in a coma. Complications developed in 30%, compared with 18% in a 2003 study, mainly respiratory depression (12%), prolonged QTc interval (6%) and hypotension (5%). Eight patients died (0.8%) and five (0.5%) survived with permanent sequelae, mainly anoxic brain damage. Discussion Few patients stayed more than two days. The use of the ICU was liberal, considering that only one out of five presented in a coma. Antidotes were frequently given diagnostically. Although N-acetylcysteine induced allergic reactions, most were mild and treatment discontinuation was only necessary once.

    Full Text Available OBJECTIVES Confirmation of Kudoa septempunctata (K. septempunctata as the pathogenic agent causing acute food poisoning remains under debate owing to inconsistencies in the reproducibility of experimental evidence. Higher intake of olive flounder infected with K. septempunctata would result in increased diagnosis of food poisoning by K. septempunctata, if the latter was one of the causal agents of acute food poisoning. The aim was to evaluate the relationship between the shipping amount of olive flounder aquacultured from Jejudo and the incidence of K. septempunctata food poisoning in 2015, Korea. METHODS Data of shipping amounts between March 2014 and February 2016 and of monthly reported events of Kudoa food poisoning were taken from Jejudo Fish-Culture Fisheries Cooperatives and Korea Centers for Disease Control and Prevention, respectively. Non-parametric correlation analyses were conducted. RESULTS Shipping amounts indicated the seasonal changes according to variation of consumption. Spearman’s rho and Kendall’s tau-a between the monthly shipping amounts and the reported events in 2015 were 0.39 (p=0.21 and 0.27 (p=0.20, respectively. CONCLUSIONS An independent relationship was noted between the shipping amount and the reported events, which contrasted with the claim that the virulence of K. septempunctata caused acute food poisoning.

    The effects of activated charcoal (AC) mixed with cathartics for gastric decontamination in the management of organophosphate (OP) poisoning remain unknown due to limited clinical evidence. This exploratory study assessed the effectiveness of premixed AC-sorbitol as a treatment for OP poisoning. This retrospective observational case study included patients who either did not receive AC-sorbitol or received a single dose of AC-sorbitol within 24 h after OP ingestion. The patients were divided into three groups: no AC-sorbitol treatment, patients who received AC-sorbitol within 1 h of OP ingestion, and patients who received AC-sorbitol more than 1 h after OP ingestion. Mortality, the development of respiratory failure, and the duration of mechanical ventilation were used as outcome measurements for effectiveness, whereas aspiration pneumonia and electrolyte imbalance were employed as safety measurements. Among 262 patients with OP poisoning, 198 were included. Of these, 133 patients did not receive AC-sorbitol, whereas 14 and 51 patients received AC-sorbitol within 1 h or more than 1 h after ingestion, respectively. The time from ingestion to hospital arrival and time from ingestion to administration of atropine and pralidoxime differed among the groups, whereas other characteristics, including age, amount ingested, and type of ingested OP, were similar among the groups. Univariate and multivariate analysis demonstrated that the administration of AC-sorbitol was not associated with outcome measures for effectiveness and did not significantly increase either aspiration pneumonia or electrolyte imbalances during hospitalization. The administration of AC-sorbitol exerted neither beneficial nor harmful effects on the outcomes of OP-poisoned patients regardless of the time from OP ingestion to administration, compared with those of patients who did not receive AC-sorbitol. However, this study enrolled a small number of patients who received AC-sorbitol; further qualified

  8. Determination of As by instrumental neutron activation analysis in sectioned hair samples for forensic purposes: chronic or acute poisoning?

    2011-01-01

    Autopsy of 29-year old woman suspicious of committing suicide by the ingestion of As 2 O 3 yielded contradictory findings. All pathological findings as well as clinical symptoms suggested acute poisoning, while a highly elevated As level of 26.4 μg g -1 in her hair collected at the autopsy, which was determined with inductively coupled plasma mass spectrometry indicated chronic poisoning. To elucidate this discrepancy, instrumental neutron activation analysis (INAA) with proven accuracy was performed of another set of sectioned hair samples. Levels of As found by INAA in the range of 0.16-0.26 μg g -1 excluded chronic poisoning, because the person died after approximately 14 h after the As 2 O 3 ingestion. Two reasons for the discordant As results obtained by ICP-MS and INAA are considered: (1) accidental, non-removed contamination of hair on the As 2 O 3 ingestion; (2) erroneous performance of ICP-MS.

    2016-10-01

    The European Plant Protection Products Regulation 1107/2009 requires that registrants establish whether pesticide metabolites pose a risk to the environment. Fish acute toxicity assessments may be carried out to this end. Considering the total number of pesticide (re-) registrations, the number of metabolites can be considerable, and therefore this testing could use many vertebrates. EFSA's recent "Guidance on tiered risk assessment for plant protection products for aquatic organisms in edge-of-field surface waters" outlines opportunities to apply non-testing methods, such as Quantitative Structure Activity Relationship (QSAR) models. However, a scientific evidence base is necessary to support the use of QSARs in predicting acute fish toxicity of pesticide metabolites. Widespread application and subsequent regulatory acceptance of such an approach would reduce the numbers of animals used. The work presented here intends to provide this evidence base, by means of retrospective data analysis. Experimental fish LC50 values for 150 metabolites were extracted from the Pesticide Properties Database (http://sitem.herts.ac.uk/aeru/ppdb/en/atoz.htm). QSAR calculations were performed to predict fish acute toxicity values for these metabolites using the US EPA's ECOSAR software. The most conservative predicted LC50 values generated by ECOSAR were compared with experimental LC50 values. There was a significant correlation between predicted and experimental fish LC50 values (Spearman rs = 0.6304, p < 0.0001). For 62% of metabolites assessed, the QSAR predicted values are equal to or lower than their respective experimental values. Refined analysis, taking into account data quality and experimental variation considerations increases the proportion of sufficiently predictive estimates to 91%. For eight of the nine outliers, there are plausible explanation(s) for the disparity between measured and predicted LC50 values. Following detailed consideration of the robustness of

    Full Text Available Objectives This study focused on the assessment of acute toxicity caused by Osthol, a major component of environment-friendly biological pesticides, by using two aquatic organisms. Methods The assessment of acute toxicity caused by Osthol was conducted in Daphnia magna and by examining the morphological abnormalities in Danio rerio embryos. Results The median effective concentration value of Osthol in D. magna 48 hours after inoculation was 19.3 μM. The median lethal concentration of D. rerio embryo at 96 hours was 30.6 μM. No observed effect concentration and predicted no effect concentration values of Osthol in D. magna and D. rerio were calculated as 5.4 and 0.19 μM, respectively. There was an increase in the morphological abnormalities in D. rerio embryo due to Osthol over time. Coagulation, delayed hatching, yolk sac edema, pericardial edema, and pigmentation were observed in embryos at 24–48 hours. Symptoms of scoliosis and head edema occurred after 72 hours. In addition, bent tails, ocular defects, and symptoms of collapse were observed in fertilized embryo tissue within 96 hours. Ocular defects and pigmentation were the additional symptoms observed in this study. Conclusions Because Osthol showed considerable toxicity levels continuous toxicity evaluation in agro-ecosystems is necessary when bio-pesticides containing Osthol are used.

    The National Health Interview Survey (NHIS) is a multipurpose household survey of the U.S. civilian non-institutionalized population conducted annually since 1957. From 1986 to 1994, over 450,000 U.S. workers, age 18 years and older, participated in a probability sampling of the entire non-institutionalized U.S. population; variables collected included a range of measures of acute and chronic disability. The objective of the present study was to assess predictors of health status, and acute and chronic disability for farmers and pesticide applicators (pesticide-exposed workers) compared to all other U.S. workers using the 1986-1994 NHIS. After adjustment for sample weights and design effects using SUDAAN, several measures of acute and chronic disability and health status were modeled with multiple logistic regression. Farmers (n = 9576) were significantly older compared to all other U.S. workers (n = 453,219) and pesticide applicators (n = 180). Farmers and pesticide applicators had a higher proportion of males, whites, and Hispanics and were less educated. After adjusting for age, gender, race-ethnicity, and education, compared to all other workers, farmers were significantly less likely to report acute and chronic disability and health conditions, while pesticide applicators were more likely to report chronic disability, health conditions, and poor health. Given the cross-sectional nature of the data and the significant job demands of farming, both leading to a relative healthy worker effect, the present results indicate that at any point in time, farmers report less acute and chronic disability, compared to other U.S. workers, whereas pesticide applicators report similar or poorer health.

    The agrarian population in low- and middle-income countries suffers from a number of adverse health effects due to pesticide exposure. In Zanzibar, the government subsidizes pesticides to enhance local rice production. The objectives of this study were to assess Zanzibar smallholder rice farmers' pesticide use and self-reported health symptoms in relation to pesticide exposure, training, and use of protective measures and to raise awareness for future local policy formulation. An exploratory cross-sectional interviewer-administered study was conducted among 99 rice farmers. Participants were selected based on convenience sampling and stratified by expected exposure category. The study participants reported using pesticides in World Health Organization (WHO) Class II. Of pesticide users, 61% reported one or more symptoms of possible acute pesticide poisoning. Only 50% of pesticide users had received training in safe handling and application of pesticides, but those who had displayed a higher use of protective measures. Farmers who did not use protective measures were more likely to have reported skin irritation and headache, which, together with eye irritation, were the most commonly reported acute symptoms. The main sociodemographic differences between the expected exposure categories of pesticide users and nonusers were in gender and education level. Scaling up of training in safe handling and application of pesticides is needed. Further studies are required to better understand the mechanisms behind the choice to use pesticides or not.

    The recreational usage of dextrometorphan, the popular antitussive medicine, has become alarming in Poland. The euphoric and hallucinogenic activity of this drug manifests after high doses, usually ranging from 225 to 1500 mg that may lead to acute poisoning. Currently, dextrometh-orphan is considered as addictive substance. In this article we describe the symptoms of acute dextrometorphan poisoning that have been observed in 11 patients, aged between 16 and 31 years that have been treated in the Department of Toxicology and Internal Diseases Raszeja Hospital in Poznan. In the course of intoxication the most frequent symptom was balance disturbation (12.50%), impaired motoric coordination (11.36%), confusion (11.36%) and papillary dilation (11.36%). Agitation (9.09%), tachycardia (7.95%), hallucinations (6.82%), disartria (5.68%) and hypertension (4.55%) were less common. The doses of dextromethorphan ranged from 4.28 to 16.67 mg/kg. All the patients were treated symptomatically. They recovered without sequelae and were discharged after 1-3 days of hospitalization.

    Objective: To investigate the etiological and demographical characteristics of acute adult poisoning cases in eastern Turkey. Methods: The retrospective study was conducted at the Emergency Department of Yuzuncu Yil University, School of Medicine, and comprised data related to the period between 2007 and 2009. The data obtained included age, gender, referrals, manner of poisoning, manner of application, the department which followed up on the patients, duration of hospital stay. All data was noted on proforma. SPSS 15 was used for statistical analysis. Results: Of the total cases visiting the Emergency Department, 1207 (1.1%) related to poisoning. Of them, 880 (72.9%) had attempted suicide; 858 (71.1%) were female; 349 (29%) were male. The average age of the females was 25.4+-8.5 years, and that of the males 28.3+-14.3 years. Single-medicine was noted in poisoning 544 (45.1%) patients. Other poisoning types were multidrugs 373 (30.9%); rat poisoning, insecticide and pesticides, 145 (12%); corrosives 38 (3.1%); and weed, mushroomang; food 47 (3.8%). Oral poisoning was noted in 1141 (94.5%) cases. A total of 1019 (84.4%) patients received treatment and were followed up in the Emergency Department. Six (0.6%) patients died. Conclusion: There is a need to generate more awareness about the hazards of domestic cleaning products and to keep it away at some distinct place to minimised chances of confusion. (author)

    Pesticides are frequently responsible for human poisoning and often the information on the involved substance is lacking. The great variety of pesticides that could be responsible for intoxication makes necessary the development of powerful and versatile analytical methodologies, which allows the identification of the unknown toxic substance. Here we developed a methodology for simultaneous identification and quantification in human blood of 109 highly toxic pesticides. The application of this analytical scheme would help in minimizing the cost of this type of chemical identification, maximizing the chances of identifying the pesticide involved. In the methodology that we present here, we use a liquid-liquid extraction, followed by one single purification step, and quantitation of analytes by a combination of liquid and gas chromatography, both coupled to triple quadrupole mass spectrometry, which is operated in the mode of multiple reaction monitoring. The methodology has been fully validated, and its applicability has been demonstrated in two recent cases involving one self-poisoning fatality and one non-fatal homicidal attempt.

    This paper aimed to analyze the effects of respiratory training on pulmonary function during the rehabilitation period for acute organic fluorine-poisoned patients treated by non-invasive positive pressure ventilation (NIPPV). Sixty-two acute organic fluorine-poisoned patients admitted to the Xinxiang Central Hospital, Xinxiang City, China, from May 2012 to March 2016 were selected and randomly divided into an observation group and a control group, with 31 cases in each. Both groups received NIPPV. The patients in the control group exercised daily, while the patients in the observation group received contracting lips-abdominal breathing training. The therapeutic effects, pulmonary ventilation function, serum levels of α-antitrypsin1 (α-AT1), surfactant protein D (SP-D), neutrophil elastase (NE), transforming growth factor beta 1 (TGF-β1), and quality of life were analyzed and compared between the two groups both before and after the administration of treatment. The total effective rate of the observation group was 93.55%, which was significantly higher when compared with the control group (74.19%) (P less than 0.05). The levels of forced expiratory volume in one second (FEV1), FEV1/FVC ratio, vital capacity (VC), carbon monoxide diffusion capacity (DLco), and maximal voluntary ventilation (MVV) of the observation group were better when compared with the control group and had statistical significance (P less than 0.05). Before treatment, the serum levels of α-AT1, SP-D, NE, and TGF-β1, and quality of life had no statistical significance in either group (P>0.05); after treatment, these indexes and the quality of life for the observation group were significantly higher when compared with the control group, with statistical significance (P less than 0.05). The respiratory training in acute organic fluorine-poisoned patients treated by NIPPV can improve the serum indexes, dilute toxicity, and recover pulmonary function, which play key roles in improving the

    In recent years, there has been increasing interest in the role of intravenous lipid formulations as potential antidotes in patients with severe cardiotoxicity caused by drug toxicity. The aim of this study was to conduct a comprehensive bibliometric analysis of all human and animal studies featuring lipid emulsion as an antidote for the treatment of acute poisoning. The Scopus database search was performed on 5 February 2016 to analyse the research output related to intravenous lipid emulsion as an antidote for the treatment of acute poisoning. Research indicators used for analysis included total number of articles, date (year) of publication, total citations, value of the h-index, document types, countries of publication, journal names, collaboration patterns and institutions. A total of 594 articles were retrieved from Scopus database for the period of 1955-2015. The percentage share of global intravenous lipid emulsion research output showed that research output was 85.86% in 2006-2015 with yearly average growth in this field of 51 articles per year. The USA, United Kingdom (UK), France, Canada, New Zealand, Germany, Australia, China, Turkey and Japan accounted for 449 (75.6%) of all the publications. The total number of citations for all documents was 9,333, with an average of 15.7 citations per document. The h-index of the retrieved documents for lipid emulsion research as antidote for the treatment of acute poisoning was 49. The USA and the UK achieved the highest h-indices, 34 and 14, respectively. New Zealand produced the greatest number of documents with international collaboration (51.9%) followed by Australia (50%) and Canada (41.4%) out of the total number of publications for each country. In summary, we found an increase in the number of publications in the field of lipid emulsion after 2006. The results of this study demonstrate that the majority of publications in the field of lipid emulsion were published by high-income countries. Researchers from

    Full Text Available Context: India is a developing country in south Asia. Rural population of this country is mostly dependant on agriculture. Pesticides, mainly the organophosphorus compounds are the most frequently used substances in agriculture and thus are easily accessible. Animal bites such as snake bite, scorpion bites are also common, as people here are mainly involved in the field work. Aims: This includes, knowing the pattern of poisoning in India along with various parameters, such as mode of poisoning, type of poison, outcome of the poisoning, the most vulnerable age group involved in poisoning, so that the study will help in rapid clinical diagnosis and immediate treatment of the cases leading to decreased mortality and morbidity. Setting and design: Retrospective observational study. Materials and Methods: The study was conducted at Govt. Hospital, Yavatmal. Poisoning cases reported to casualty and post-mortem cases of poisoning brought to the hospital from 01/06/2003 to 30/05/2004 were included in the study. Result: Total 1003 patients studied; acute poisoning in the age group of 21-30 years was the most common with higher frequency in males. Most common mode was suicidal. Most common agent responsible for poisoning was organophosphorus compounds followed by snake bite. Overall mortality due to poisoning was 12%. It was highest in insecticidal poisoning. Conclusion: It was seen that adults between 21 and 30 years of age were more prone to suicidal poisoning with organophosphorous compounds followed by accidental poisoning due to snake bite. Steps are needed to be taken to educate the people, to improve their socioeconomic status and also to provide better treatment facilities at grass root level.

    Cyanide is rapidly reacting and causes arrest of aerobic metabolism. The symptoms are diffuse and lethal and require high clinical suspicion. Remediation of symptoms and mortality is highly dependent on quick treatment with a cyanide antidote. Presently, there are two widely accepted antidotes: sodium thiosulfate and hydroxocobalamin. These treatments act on different components of cyanide's metabolism. Here, we present two cases resulting from the same source of cyanide poisoning and the use of both antidotes separately used with differing outcomes.

    In developing countries, including Sri Lanka, a high proportion of acute poisoning and other medical emergencies are initially treated in rural peripheral hospitals. Patients are then usually transferred to referral hospitals for further treatment. Guidelines are often used to promote better patient care in these emergencies. We conducted a cluster randomized controlled trial (ISRCTN73983810) which aimed to assess the effect of a brief educational outreach ('academic detailing') intervention to promote the utilization of treatment guidelines for acute poisoning. This cluster RCT was conducted in the North Central Province of Sri Lanka. All peripheral hospitals in the province were randomized to either intervention or control. All hospitals received a copy of the guidelines. The intervention hospitals received a brief out-reach academic detailing workshop which explained poisoning treatment guidelines and guideline promotional items designed to be used in daily care. Data were collected on all patients admitted due to poisoning for 12 months post-intervention in all study hospitals. Information collected included type of poison exposure, initial investigations, treatments and hospital outcome. Patients transferred from peripheral hospitals to referral hospitals had their clinical outcomes recorded. There were 23 intervention and 23 control hospitals. There were no significant differences in the patient characteristics, such as age, gender and the poisons ingested. The intervention hospitals showed a significant improvement in administration of activated charcoal [OR 2.95 (95% CI 1.28-6.80)]. There was no difference between hospitals in use of other decontamination methods. This study shows that an educational intervention consisting of brief out-reach academic detailing was effective in changing treatment behavior in rural Sri Lankan hospitals. The intervention was only effective for treatments with direct clinician involvement, such as administering activated

  14. Lead poisoning

    1952-01-01

    Three cases of acute lead poisoning of cattle herds via ingestion are reported, and reference is made to several other incidents of lead in both humans and animals. The quantity of lead which was found in the livers of the dead cows varied from 6.5 to 19 mg/kg, while 1160 mg/kg of lead in the liver was found for a young cow which was poisoned experimentally with 5 gms of lead acetate per day; hence, there appears to be great variability in the amounts deposited that can lead to intoxication and death. No evidence was found for a lead seam around the teeth, prophyrinuria, or basophil granules in the erythrocytes during acute or chronic lead poisoning of cattle or horses examined. Reference is made to attempts of finding the boundary line between increased lead absorption and lead intoxication in humans, and an examination of 60 laborers in an offset-printing office containing a great deal of inhalable lead (0.16 to 1.9 mg/cu m air) is reviewed. Physical deviation, basophylic granulation of erythrocytes, increased lead content of the urine, and porphyrinuria only indicate an increased absorption of lead; the use of the term intoxication is justified if, in addition, there are complaints of lack of appetite, constipation, fatigue, abdominal pain, and emaciation.

  15. Acute poisoning following ingestion of medicines: initial management. How to treat life-threatening complications and to evaluate the risk of delayed effects and psychological distress.

    Science.gov (United States)

    2010-12-01

    Acute poisoning following ingestion of medications, both intentional and unintentional, is frequent and more or less severe. It is often unclear whether a toxic dose has been ingested. This review examines the initial management of patients with suspected acute poisoning, based on a review of the literature using the standard Prescrire methodology. We examined clinical practice guidelines, which are mostly based on observational, pharmacological and toxicological data, as well as empirical data. Few comparative trials are available. In life-threatening situations, the first priority is to call an emergency response mobile unit and to implement life-support techniques, i.e., resuscitation for cardiorespiratory arrest; respiratory support if necessary; and the left lateral head-down position and glucose injection if the patient is unconscious. Prompt, initial measures may also include: anticonvulsant injection for status epilepticus (diazepam, for example); a sedative for extreme agitation (diazepam or clorazepate if there is no risk of respiratory depression; otherwise haloperidol); atropine for severe bradycardia; elevating the legs for hypotension; and naloxone in case of respiratory depression due to opioids. Drug poisoning can be life-threatening.The extent of the risk should be assessed by questioning the patient and close contacts, examining the immediate environment, and carrying out a clinical examination to identify a major toxic condition. The severity of poisoning is assessed by gathering all information about the patient, the drug(s) ingested, the circumstances of ingestion, and any other substances ingested at the same time. A poison control centre may be called to assist with diagnosis, to predict the clinical consequences, and to guide patient management. Activated charcoal can reduce the gastrointestinal absorption of some drugs. It should be given as soon as possible, preferably within 2 hours after ingestion of a drug known to be adsorbed by

    Full Text Available Purpose: Several criteria have been suggested to estimate the intoxication severity, yet so far no system of clinical criteria has been developed to determine the duration of hospitalisation. The forecast is linked to the influence of the extended corrected QT interval and GCS (Glasgow Coma Scale on the frequency of the developing acute pulmonary insufficiency and lethality. The average duration of hospital treatment is also crucial. First of all, it is determined by the intoxication severity and lasts from 3 to 26 days. The aim of this study is to develop an individual forecast about the duration of hospitalisation for patients suffering from acute exogenous intoxication with organophosphorus pesticides (OPP. Materials/Methods: The subjects are 160 patients. We use statistical regression analysis to study the significance of 5 of the most typical clinical indicators of organophosphorus intoxication on the duration of hospitalisation: type of conscience, presence of spasms, pulmonary oedema, shock and multi-organ insufficiency syndrome (MOIS. To forecast the treatment length, we obtain simplified mathematical expressions in the form of score estimates. Results: The significance of the clinical indicators “MOIS”, “conscience” and “spasm” has been confirmed. A forecast matrix that gives the opportunity to forecast the personal duration of hospital treatment for each patient has been built.

    Carbon monoxide is a toxic gas for humans and is still a silent killer in both developed and developing countries. The aim of this case series was to evaluate early radiological images as a predictor of subsequent neuropsychological sequelae, following carbon monoxide poisoning. After carbon monoxide exposure, early computed tomography scans and magnetic resonance imaging findings of a 52-year-old woman showed bilateral lesions in the globus pallidus. This patient was discharged and followed for 90 days. The patient recovered without any neurological sequela. In a 58-year-old woman exposed to carbon monoxide, computed tomography showed lesions in bilateral globus pallidus and periventricular white matter. Early magnetic resonance imaging revealed changes similar to that like in early tomography images. The patient recovered and was discharged from hospital. On the 27th day of exposure, the patient developed disorientation and memory impairment. Late magnetic resonance imaging showed diffuse hyperintensity in the cerebral white matter. White matter lesions which progress to demyelination and end up in neuropsychological sequelae cannot always be diagnosed by early computed tomography and magnetic resonance imaging in carbon monoxide poisoning.

    Up to date information on poisoning trends is important. This study reports the epidemiology of all hospitalized acute poisonings in Oslo, including mortality, follow-up referrals, and whether the introduction of over-the-counter sales of paracetamol outside pharmacies had an impact on the frequency of poisonings. All acute poisonings of adults (≥16 years) treated at the five hospitals in Oslo from April 2008 to April 2009 were included consecutively in an observational cross-sectional multicentre study. A standardized form was completed by the treating physician, which covered the study aims. All deaths by poisoning in and outside hospitals were registered at the Institute of Forensic Medicine. There were 1065 hospital admissions of 912 individuals; 460 (50%) were male, and the median age was 36 years. The annual incidence was 2.0 per 1000. The most frequent toxic agents were ethanol (18%), benzodiazepines (15%), paracetamol (11%), and opioids (11%). Physicians classified 46% as possible or definite suicide attempts, 37% as accidental overdoses with substances of abuse (AOSA), and 16% as other accidents. Twenty-four per cent were discharged without any follow-up and the no follow-up odds were highest for AOSA. There were 117 deaths (eight in hospital), of which 75% were males, and the median age was 41 years. Thus, the annual mortality rate was 25 per 100 000 and the in-hospital mortality was 0.8%. Opioids were the most frequent cause of death. The incidence of hospitalized acute poisonings in Oslo was similar to that in 2003 and there was an equal sex distribution. Compared with a study performed in Oslo in 2003, there has been an increase in poisonings with a suicidal intention. The in-hospital mortality was low and nine out of ten deaths occurred outside hospitals. Opioids were the leading cause of death, so preventive measures should be encouraged among substance abusers. The number of poisonings caused by paracetamol remained unchanged after the

    Poisoning exposures continue to be a significant cause of morbidity and mortality worldwide. The lack of facilities, treatment resources, and antidotes in hospitals may affect the treatments provided and outcomes. This study aimed to determine the availability of gastrointestinal (GI) decontamination, stabilisation, elimination enhancement resources, and antidotes for the management of acute toxic exposures and poisonings in emergency departments (EDs) among various types of governmental and private hospitals in Palestine. A cross-sectional study using semi-structured questionnaire was performed. Data were collected based on hospital resources; GI decontamination, stabilisation, elimination enhancement resources and antidotes from Palestinian hospitals. Eighteen hospitals (94.7%) have responded. Among them, paracetamol poisoning was the most frequently reported cases by EDs (mean frequency score = 7.6 ± 2.1), followed by bee stings (mean = 6.9 ± 2.7) and organophosphate poisoning (mean = 6.7 ± 2.7). The availabilities of most resources related to GI decontamination items varied substantially with hospital type, but these differences were not statistical significant. The availability of stabilisation resources was not significantly different between hospitals types. For the availability of techniques used to enhance the elimination of toxic substances, there were variations between the hospitals types. However, these differences were not statistical significant, except for haemodialysis (p = 0.003) which was more available in governmental hospitals. For the availability of antidotes, none of the hospitals had sufficient stock of all antidotes listed. In relation to hospital type, there was variability in the availability of antidotes, but this did not reach statistical significance, except for deferoxamine (p management of acute toxic exposure and poisoning. The implementation of a minimum list of antidotes and treatment resources would be useful to increase the

    The "opening" of the post-totalitarian societies of Eastern Europe increased the illegal spread of psychoactive substances (PAS) in the past decade. We studied psychoactive substance acute poisoning (PAS AP)--types of toxic agents involved, incidence rates, and their changes--as indirect indicators of the characteristics, magnitude and development of the problem in Bulgaria during the 1990-2000 period of socioeconomic transition and crisis after collapse of communism. The study analyzed retrospectively the caseload of all 571 PAS acute poisonings that occurred in the territory: 417 men (73%) and 154 women (27%); mean age 24.07y (range 10-75). The number of all AP and PAS AP showed a marked increase during the last 3years of the studied period, especially in 2000. The average PAS AP incidence rate for 1998-2000 (13.50/100,000) compared to the mean value for the preceding period 1990-1997 (5.76/100,000) showed a 2.34 fold increase. Acute alcohol intoxication was 62.7%, of all PASAP; the opioid 15.2% (heroin 11.0%, other opioids 4.2%); prescribed and over the counter drugs 12.6%; inhalants 1.1%; cannabis 1.1%; and cocaine 0.7%. Amphetamine (or amphetamine-like), hallucinogens and phencyclidine (or phencyclidine-like) AP were not encountered. The average percentage of alcohol AP for 1998-2000 compared to the preceding 1990-1997 dropped from 78.12% to 44.72% (1.75 fold), while that of opioids rose from 6.59% to 26.47% (4.02 fold), and that of the other drugs group from 12.22% to 21.78% (1.78 fold increase). The new non-alcoholic PAS AP (heroin, cocaine, inhalants and cannabis AP, as indirect indicators of narcotic exposure) showed a rapid increase. The data showed they are expanding and catching up with alcohol as a new cause of substance-related problems, thus becoming one of the important health and social problems of post-totalitarian society.

    A shipyard worker was poisoned by hydrogen sulfide (H2S), and rescued after 15-20 min. He regained consciousness after 2 days. Three days later his condition deteriorated, and he was more or less comatose for a month. When he woke up, he was amnesic, nearly blind, had reduced hearing, and had a moderate spastic tetraparesis and ataxia. Two months after the accident, he had greatly improved. Audiograms showed hearing loss with maximum at 2000 Hz and significantly poorer speech discrimination. EEG showed generalized dysrhythmia. At follow-up 5 years later he had not been able to resume his work, and had slight motor, memory and visual symptoms. CT and MRI showed slight cerebral atrophy. EEG and evoked responses were normal.

  3. Acute and chronic methyl mercury poisoning impairs rat adrenal and testicular function

    Animals poisoned with methyl mercury (CH/sub 3/Hg) exhibit stress intolerance and decreased sexual activity, which suggest both adrenal and testicular dysfunction. Adrenal and testicular function was studied in male rats after treatment with CH/sub 3/Hg. In animals treated chronically, the adrenal glands were markedly hyperplastic with enlargement of the zona fasciculata. The mean basal serum levels of corticosterone were similar in experimental (17.8 ..mu..g/dl) and control (16.8 ..mu..g/dl) groups. However, with ether stress, experimental animals had a subnormal response, and the mean serum levels of corticosterone increased to only 23.9 ..mu../dl compared to 40.6 ..mu..g/dl in the controls. Exogenous ACTH stimulation produced a mean level of 19.0 ..mu..g/dl in the CH/sub 3/Hg-treated animals and 49.7 ..mu..g/dl in the controls. In vitro studies demonstrated a defect in the conversion of cholesterol to pregnenolone. A profound impairment in swimming was partially reversed with glucocorticoid therapy. In animals treated with CH/sub 3/Hg, serum testosterone was lower than normal in the basal state. Human chorionic gonadotropin stimulation increased the mean serum concentration of testosterone to 23.4 ng/ml in controls, but it was only 4.50 ng/ml in experimental animals. The data indicate that CH/sub 3/Hg poisoning impairs adrenal and testicular steroid hormone secretion, which accounts in part for the diminished stress tolerance and decreased sexual activity observed in CH/sub 3/Hg-intoxicated animals.

    Recent news from Syria on a possible use of chemical warfare agents made the headlines. Furthermore, the motivation of terrorists to cause maximal harm shifts these agents into the public focus. For incidents with mass casualties appropriate medical countermeasures must be available. At present, the most important threats arise from nerve agents and sulfur mustard. At first, self-protection and protection of medical units from contamination is of utmost importance. Volatile nerve agent exposure, e.g. sarin, results in fast development of cholinergic crisis. Immediate clinical diagnosis can be confirmed on-site by assessment of acetylcholinesterase activity. Treatment with autoinjectors that are filled with 2mg atropine and an oxime (at present obidoxime, pralidoxime, TMB-4 or HI-6) are not effective against all nerve agents. A more aggressive atropinisation has to be considered and more effective oximes (if possible with a broad spectrum or a combination of different oximes) as well as alternative strategies to cope with high acetylcholine levels at synaptic sites should be developed. A further gap exists for the treatment of patients with sustained cholinergic crisis that has to be expected after exposure to persistent nerve agents, e.g. VX. The requirement for long-lasting artificial ventilation can be reduced with an oxime therapy that is optimized by using the cholinesterase status for guidance or by measures (e.g. scavengers) that are able to reduce the poison load substantially in the patients. For sulfur mustard poisoning no specific antidote is available until now. Symptomatic measures as used for treatment of burns are recommended together with surgical or laser debridement. Thus, huge amounts of resources are expected to be consumed as wound healing is impaired. Possible depots of sulfur mustard in tissues may aggravate the situation. More basic knowledge is necessary to improve substantially therapeutic options. The use of stem cells may provide a new

    Organophosphorus pesticides (OPs) and carbamate pesticides (CPs) are among the most widely used pesticides in China, playing a major role in protecting agricultural commodities. In this study, we determined the cumulative acute exposure to OPs and CPs of Shanghai residents from vegetables and fruits (VFs). The food consumption data were obtained from the Shanghai Food Consumption Survey (SHFCS) of 2012-14 including a total of 1973 participants aged 2-90 years. The pesticide residue data were obtained from the Shanghai monitoring programme during 2008-11 with 34 organophosphates and 11 carbamates analysed in a total of 5335 samples of VFs. A probabilistic approach was performed as recommended by the EFSA, using the optimistic model with non-detects set as zero and with processing factors (PFs) being used and the pessimistic model with non-detects replaced by limit of detection (LOD) and without PFs. We used the relative potency factor (RPF) method to normalise the various pesticides to the index compound (IC) of methamidophos and chlorpyrifos separately. Only in the pessimistic model using methamidophos as the IC was there was small risk of exposure exceeding the ARfD (3 µg kg - 1 bw day - 1 ) in the populations of preschool children (0.029%), school-age children (0.022%) and adults (0.002%). There were no risk of exposure exceeding the ARfD of methamidophos in the optimistic model and of chlorpyrifos (100 µg kg - 1 bw day - 1 ) in both optimistic and pessimistic models in all three populations. Considering the Chinese habits of overwhelmingly eating processed food (vegetables being cooked, and fruits being washed or peeled), we conclude that little acute risk was found for the exposure to VF-sourced OPs and CPs in Shanghai.

    Our previous findings revealed that increased oxidative stress, apoptosis and necrosis were implicated in acute fluoride (F - ) induced cardiac dysfunction apart from hypocalcemia and hyperkalemia. Cardiac intermediate filaments (desmin and vimentin) and cytoskeleton linker molecule vinculin plays an imperative role in maintaining the architecture of cardiac cytoskeleton. In addition, AMPK is a stress activated kinase that regulates the energy homeostasis during stressed state. The present study was aimed to examine the role of cytoskeletal proteins and AMPK signaling molecules in acute F - induced cardiotoxicity in rats. In order to study this, male Wistar rats were treated with single oral doses of 45 and 90mg/kgF - for 24h. Acute F - intoxicated rats showed declined cytoskeletal protein expression of desmin, vimentin and vinculin in a dose dependent manner compared to control. A significant increase in phosphorylation of AMPKα (Thr172), AMPKß1 (Ser108) and Acetyl-coA carboxylase (ACC) (Ser79) in the myocardium and associated ATP deprivation were found in acute F - intoxicated rats. Further, ultra-structural studies confirmed myofibril lysis with interruption of Z lines, dilated sarcoplasmic reticulum and damaged mitochondrion were observed in both the groups of F - intoxicated rats. Taken together, these findings reveal that acute F - exposure causes sudden heart failure by altering the expression of cytoskeletal proteins and AMPK signaling molecules.

  1. Pesticide exposure - Indian scene

    International Nuclear Information System (INIS)

    Gupta, P.K.

    2004-01-01

    Use of pesticides in India began in 1948 when DDT was imported for malaria control and BHC for locust control. India started pesticide production with manufacturing plant for DDT and benzene hexachloride (BHC) (HCH) in the year 1952. In 1958, India was producing over 5000 metric tonnes of pesticides. Currently, there are approximately 145 pesticides registered for use, and production has increased to approximately 85,000 metric tonnes. Rampant use of these chemicals has given rise to several short-term and long-term adverse effects of these chemicals. The first report of poisoning due to pesticides in India came from Kerala in 1958 where, over 100 people died after consuming wheat flour contaminated with parathion. Subsequently several cases of pesticide-poisoning including the Bhopal disaster have been reported. Despite the fact that the consumption of pesticides in India is still very low, about 0.5 kg/ha of pesticides against 6.60 and 12.0 kg/ha in Korea and Japan, respectively, there has been a widespread contamination of food commodities with pesticide residues, basically due to non-judicious use of pesticides. In India, 51% of food commodities are contaminated with pesticide residues and out of these, 20% have pesticides residues above the maximum residue level values on a worldwide basis. It has been observed that their long-term, low-dose exposure are increasingly linked to human health effects such as immune-suppression, hormone disruption, diminished intelligence, reproductive abnormalities, and cancer. In this light, problems of pesticide safety, regulation of pesticide use, use of biotechnology, and biopesticides, and use of pesticides obtained from natural plant sources such as neem extracts are some of the future strategies for minimizing human exposure to pesticides

    ámetros oficiales de monitorización deben ser reevaluados para mejor protección de los trabajadores. La ocurrencia de intoxicaciones a partir de la percepción de los trabajadores estuvo dentro de lo esperado, pero la estimación con base en la clasificación de la OMS captó una proporción mayor de casos.OBJECTIVE: To describe the occupational exposure to acute poisoning by pesticides, especially organophosphates, and its incidence. METHODS: A descriptive study was carried out on 290 family fruit farmers in the municipality of Bento Gonçalves, Southern Brazil, conducted in two stages in 2006. Two hundred and forty-one of these workers completed the two stages, which corresponded to periods of low use and intense use of pesticides. Data on the property, occupational exposure to pesticides, sociodemographic data and frequency of health problems were gathered using a standardized questionnaire. Poisoning was characterized by reports of episodes, symptoms relating to pesticides and plasma cholinesterase examinations. Cases were classified according to the matrix proposed by the World Health Organization (WHO. RESULTS: On average, each property used 12 different types of pesticides, consisting mainly of glyphosate and organophosphates. Most of the workers used tractors for pesticide application (87%, set aside the containers for selective garbage collection (86% and used protective equipment during activities involving pesticides (= 94%. Among these family farmers, 4% reported occurrences of poisoning by pesticides over the 12 months preceding the investigation, and 19% at some time during their lives. According to the criterion proposed by WHO, 11% were classified as probable cases of acute poisoning. Among the workers who had used organophosphates over the ten-day period preceding the examination, 2.9% presented two or more symptoms relating to pesticides and a 20% reduction in cholinesterase. CONCLUSIONS: The poisoning occurrences according to the workers' perceptions were

    Full Text Available This article reports cases of nitrate poisoning in Indian indigenous cattle breeds comprising two Gir cows aging 4 years each, and one Barugur cow at 1.5 years of age. The cattle with case history of sudden death and oozing of partially clotted blood from the anal opening were brought to the Central University Laboratory (CUL, Center for Animal Health Studies (CAHS, Tamil Nadu Veterinary and Animal Sciences University (TANUVAS for diagnostic investigation with a suspicion of anthrax. According to anamnesis, all the animals were clinically normal and did not reveal any abnormality on the previous day. The animals were fed with recently harvested sorghum leaves and stalks. Smears examined for anthrax were found negative. Biological test (mice inoculation for anthrax was also negative. Gross lesions on necropsy examination of the carcases were suggestive of nitrate intoxication. Finally, nitrate intoxication of these cattle was confirmed by chemical and toxicological analysis of fodder, rumen content, aqueous humor, liver, kidney and urine.

    A 53-year-old woman ingested about 300 mL of 95% methanol. After immediate ethanol antagonist therapy and hemodialysis, she recovered completely. Few days later, the plasma concentration of methanol and formate was measured. A gas chromatography was used for the plasma methanol concentration measurement, and a colorimetric method was used for plasma formate concentration measurement (Formate Colorimetric Assay Kit; BioVision, California, USA). Patient's plasma methanol concentration before hemodialysis was 676.9 mg/dL and plasma formate concentration was 16.9 mg/dL. By removing blood methanol and formate using hemodialysis before formate accumulations in the body, the patient was discharged without any sequelae. We were able to obtain correlation between a gas chromatography and colorimetric method without gas chromatography-mass spectrometry, with good correlation coefficients. The sensitivity was sufficient for analyzing blood sample. Monitoring formate concentration is useful in determining the treatment and evaluating the prognosis of methanol poisoning. We suggest that this colorimetric method is useful in a facility with no access to a gas chromatography in order to measure a plasma formate concentration.

    Full Text Available Severe mercury intoxication is very rare in developed countries, but still occurs as the result of volatile substance abuse, suicide attempts, occupational hazards, or endemic food ingestion as reported in the cases of public health disasters in Iraq and in Minamata Bay, Japan. Here, we describe the dramatic physical and cognitive decline of a 23-year-old patient caused by a severe methyl mercury (MeHg intoxication of unknown origin. We show serial magnetic resonance imaging (MRI of the patient’s brain, as well as ex vivo analyses of blood and cerebrospinal fluid including multicolor flow cytometric measurements, functional assays of hemostaseologic efficacy, and evaluation of regulatory effector molecules. Together with the clinical history, our findings show the progressive neuronal degeneration accompanying the deterioration of the patient. Moreover, the ex vivo analyses display alterations of thrombocyte function and coagulation, as well as an immunological milieu facilitating autoimmunity. Despite the successful reduction of the MeHg concentration in the patient’s blood with erythrocyte apheresis and chelator therapy, his condition did not improve and led to a persistent vegetative state. This case illustrates the neurotoxicity of MeHg following severe intoxication for the first time by serial MRI. Data on immune-cell and thrombocyte function as well as on coagulation in mercury poisoning reveal potential implications for anticoagulation and immunomodulatory treatment.

    The objective was to develop alginate beads that could adsorb lead ions in gastric pH, in view to preconize their use in gastric lavage following lead poisoning. The swelling measurements of both, dry and hydrated beads, were carried out in simulated gastric fluid (SGF). The sorption kinetics was examined at lead concentrations ranging from 50 to 200mg/l. Calcium released during the sorption process was investigated. The swelling rate of the dry beads increased considerably with time increase and reached the equilibrium at 736% after 240min; concerning the hydrated beads, the equilibrium swelling reached 139% after 180min. The adsorption of Pb (II) in SGF by dry beads increased with the increase of time and initial lead concentration. The adsorption kinetics of Pb ions by hydrated alginate beads indicated a rapid binding of Pb ions to the sorbent during the first 15min for all the concentrations, followed by a slow increase until the equilibrium was reached after 90min. The adsorption capacity of Pb ions increased with the increase of the storage time in water at 4°C and with the weight. The amount of Ca 2+ released by the beads increased with the increase of Pb ions a rate. Copyright © 2017 Elsevier B.V. All rights reserved.

    2016-01-01

    Full Text Available Barium is a heavy divalent alkaline earth metal that has been known as a muscle poison. Barium can cause human toxicity, which may lead to significant hypokalemia and have serious consequences. This paper reports a case of unprecedented barium intoxication in which the patient, who suffered from depression, swallowed at least 3.0 g barium chloride to commit suicide. On admission, the patient presented with nausea, vomiting, stomach burning feeling, dizziness, and weakness. Emergency biochemical testing showed that the patient was suffering from severe hypokalemia (K+ 1.7 mmol/L. His electrocardiogram (ECG prompted atrioventricular blocking, ventricular tachycardia, prolongation of PR interval, ST segment depression with U waves, and T wave inversion. Intravenous potassium supplements were given immediately to correct hypokalemia and regular monitoring of vital signs and fluid balance was arranged. After all-out rescue of our hospital personnel, the condition of the patient is currently stable and he is gradually recovering. This case exemplifies the weaknesses of the management of toxic substances and the lack of mental health education for young people. We hope to get more attention for the supervision of toxic substances and the healthy development of young people.

    Full Text Available Background. Acute carbon monoxide poisoning (ACOP is a significant cause of morbidity and mortality in many countries. Twelve Hand Jing Points (THJP have been believed to be effective to treat all kinds of emergency calls in traditional Chinese medicine (TCM for more than 3000 years. This randomized controlled trial (RCT is designed to evaluate the effectiveness of THJP in curing acute carbon monoxide poisoning in first aid treatment. This paper reports the protocol of the trial. Methods/Design. This RCT is a multicenter, randomized, controlled study undergoing in China. The compliant patients are divided into the bloodletting group and standard of care group. With first aid treatments given to both of the groups, the bloodletting group is bleeding at THJP upon being hospitalized. Primary outcomes and secondary outcomes will be measured and compared between these two groups. Before treatment, immediately after treatment, and 30 minutes, 1 hour, and 4 hours after treatment, patients’ basic vital signs and state of consciousness were observed. Before treatment and 1 and 4 hours after treatment, carboxyhemoglobin concentration in venous blood samples was detected. Discussion. The objective of this study is to provide convincing evidence to clarify the efficacy and safety of THJP for early treatment of acute carbon monoxide poisoning.

    Data on emergency interventions in poisonings are scarce. Objective To determine the effectiveness of antidote therapy in acute poisoning-related emergency medical services (EMS) interventions. A prospective observational study included all poisoning-related intervention cases over 3 years (1999-2001) in the Celje region, Slovenia, covering 125,000 inhabitants. Data were recorded on an EMS form. Psychoactive agents were present in 56.5% out of 244 poisoning-related EMS interventions. Prescription drugs were a cause of intoxication in 93 (39.2%) cases alone or in combination with alcohol or illegal drugs. More than one fifth of poisonings were due to the use of illegal drugs in 52 (21.9%) cases, 43 (18.1%) out of them heroin related. At the time of EMS arrival, more patients who ingested illegal drugs were in coma or comatose than the rest. 24 (45.3%) vs. 32 (17.3%) of poisoned patients were in coma (p < 0.001). Glasgow Coma Scale (GCS) at the first contact was lower in patients who ingested illegal drugs than in the remaining patients (9.0 vs. 11.6, p = 0.001). In 23.2% of the cases, an antidote was administered. In 29 (12.2%) naloxone and in 16 (6.7%) flumazenil was administered. Mean GCS after intervention was higher in all cases but significantly higher in illegal drug cases, 13.4 vs. 12.2 (p = 0.001), with a mean positive change in GCS of 4.5 vs. 0.6 (p < 0.001). In illegal drug users, mean change after antidote administration was 8.2 vs. 0.5 without antidote administration (p < 0.001). High rate of successful antidote use during the intervention indicated the importance of good EMS protocols and the presence of a skilled doctor in the EMS team.

    Full Text Available Delayed encephalopathy after acute carbon monoxide poisoning (DEACMP is more characteristic of anoxic encephalopathy than of other types of anoxia. Those who have the same poisoning degree and are of similar age and gender have a greater risk of getting DEACMP. This has made it clear that there are obvious personal differences. Genetic factors may play a very important role. The authors performed a genome-wide association study involving pooling of DNA obtained from 175 patients and 244 matched acute carbon monoxide poisoning without delayed encephalopathy controls. The Illumina HumanHap 660 Chip array was used for DNA pools. Allele frequencies of all SNPs were compared between delayed encephalopathy after acute carbon monoxide poisoning and control groups and ranked. A total of 123 SNPs gave an OR >1.4. Of these, 46 mapped in or close to known genes. Forty-eight SNPs located in 19 genes were associated with DEACMP after correction for 5% FDR in the genome-wide association of pooled DNA. Two SNPs (rs11845632 and rs2196447 locate in the Neurexin 3 gene were selected for individual genotyping in all samples and another cohort consisted of 234 and 271 controls. There were significant differences in the genotype and allele frequencies of rs11845632 and rs2196447 between the DEACMP group and controls group (all P-values <0.05. This study describes a positive association between Neurexin 3 and controls in the Han Chinese population, and provides genetic evidence to support the susceptibility of DEACMP, which may be the resulting interaction of environmental and genetic factors.

  13. Relationship between exposure duration, carboxyhemoglobin, blood glucose, pyruvate and lactate and the severity of intoxication in 39 cases of acute carbon monoxide poisoning in man

    The relationship between exposure duration, COHb, blood glucose, pyruvate and lactate and the severity of intoxication was investigated in a group of 39 cases of acute CO poisoning treated in the Clinical Toxicology Center in Lodz, Poland. On the basis of clinical criteria the patients were classified into cases of mild, moderate, severe and very severe CO poisoning. COHb and carbohydrate metabolites were estimated in venous blood taken immediately after admission of the patient to hospital prior to treatment. The severity of intoxication did not correlate with blood COHb; variation in exposure duration seems to be responsible for this phenomenon. Severe and very severe poisonings were associated with longer exposures and were accompanied by a markedly higher blood lactate level, compared to mild and moderate cases. Blood pyruvate depended less than lactate on the severity of intoxication. Blood glucose depended neither on exposure duration nor on the severity of intoxication. Among the carbohydrate metabolic parameters studied, blood lactate determination can be helpful in the evaluation of the severity of CO poisoning in man.

    Hydroxocobalamin is a Food and Drug Administration-approved antidote for cyanide poisoning. Cobinamide is a potential antidote that contains 2 cyanide-binding sites. To our knowledge, no study has directly compared hydroxocobalamin with cobinamide in a severe, cyanide-toxic large-animal model. Our objective is to compare the time to return of spontaneous breathing in swine with acute cyanide-induced apnea treated with intravenous hydroxocobalamin, intravenous cobinamide, or saline solution (control). Thirty-three swine (45 to 55 kg) were intubated, anesthetized, and instrumented (continuous mean arterial pressure and cardiac output monitoring). Anesthesia was adjusted to allow spontaneous breathing with FiO2 of 21% during the experiment. Cyanide was continuously infused intravenously until apnea occurred and lasted for 1 minute (time zero). Animals were then randomly assigned to receive intravenous hydroxocobalamin (65 mg/kg), cobinamide (12.5 mg/kg), or saline solution and monitored for 60 minutes. A sample size of 11 animals per group was selected according to obtaining a power of 80%, an α of .05, and an SD of 0.17 in mean time to detect a 20% difference in time to spontaneous breathing. We assessed differences in time to death among groups, using Kaplan-Meier estimation methods, and compared serum lactate, blood pH, cardiac output, mean arterial pressure, respiratory rate, and minute ventilation time curves with repeated-measures ANOVA. Baseline weights and vital signs were similar among groups. The time to apnea and cyanide dose required to achieve apnea were similar. At time zero, mean cyanide blood and lactate concentrations and reduction in mean arterial pressure from baseline were similar. In the saline solution group, 2 of 11 animals survived compared with 10 of 11 in the hydroxocobalamin and cobinamide groups (Pcyanide concentrations became undetectable at the end of the study in both antidote-treated groups, and no statistically significant differences

    Neurotrophins are the family of proteins which stimulate and regulate the process of neurogenesis. Several factors belong to the family, mainly nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT 3), and neurotrophin-4/5 (NT-4/5). Acute poisoning with carbon monoxide (CO), which usually is accompanied by neurologic symptoms, can potentially change the secretion profile of neurotrophins. Aim of the study. The main goal of the study is to assess the changes of NGF and BDNF plasma levels during an acute phase of CO poisoning as well as immediately after recovery. Additionally, the relationship among neurotrophin levels and selected aspects of clinical course of CO poisoning were studied. The study group consisted of 18 patients (mean age: 31.8±10.3 years) hospitalized in Toxicology Department of University Hospital in Cracow because of acute CO poisoning. There were 10 women (mean age: 30.2±6.9 years) and 8 men (mean age 33.9±13.7 years) in the group. The levels of NGF and BDNF were evaluated using immunoenzymatic method (ELISA) in plasma samples taken thrice in each patient. The sample 1. was taken during hospital admission, the sample 2. about 12-36 hours after admission, and the sample 3. just before the hospital discharging (usually, on the 3rd-4th day). The clinical data were collected from patients’ anamnesis, physical examination and neuropsychological evaluation. The statistical analysis were performed using tools comprised in STATISTICA 12.0 PL (StatSoft Polska, Cracow, Poland) software. The majority of NGF plasma levels were less than 14 pg/mL (values below the limit of quantification), contrary to the sole case of 34.3 pg/mL. BDNF plasma levels ranged from 4.8 ng/mL to above 48 ng/mL, i.e. they were higher than the upper limit of measurement range for the plasma dilution which had been used. The comparison of NGF and BDNF plasma levels in the study group with their analogues in healthy volunteers taken from the

    Full Text Available Literature regarding acute human toxicity of thiopurines is limited to a handful of case reports. Our objectives were to describe all cases of overdose with thiopurines reported to the Swiss Toxicological Information Centre between 1995-2013. A retrospective analysis was performed to determine circumstances, magnitude, management and outcome of overdose with these substances. A total of 40 cases (14 paediatric were reported (azathioprine, n = 35; 6-mercaptopurine, n = 5. Of these, 25 were with suicidal intent, 12 were accidental and 3 were iatrogenic errors. The magnitude of overdose ranged from 1.5 to 43 (median 8 times the usual dose in adults. Twelve cases (30% had attributable symptoms. The majority of these were minor and included gastrointestinal complaints and liver function test and blood count abnormalities. Symptoms were experienced by patients who took at least 1.5-times their usual daily thiopurine dose. Overdoses over two or more consecutive days, even if of modest size, were less well tolerated. One case of azathioprine and allopurinol co-ingestion over consecutive days led to agranulocytosis. Decontamination measures were undertaken in 11 cases (10 activated charcoal, 1 gastric lavage and these developed fewer symptoms than untreated patients. This study shows that acute overdoses with thiopurines have a favourable outcome in the majority of cases and provides preliminary evidence that gastrointestinal decontamination with activated charcoal may reduce symptom development after overdose of these substances if patients present to medical services soon after ingestion.

    Full Text Available Pesticides is a collective term for a group of chemicals used predominantly in agriculture and against vectors in vectorborne diseases such as malaria, filariasis, etc. Organophosphates (OP have become nowadays the most widely used pesticides among the world. However, they are very highly toxic to humans. Poisoning with OP is a life - threatening condition. It is responsible for the symptoms due to a cholinergic effects. The Acetylcholinesterase (ACHE enzyme inhibition leads to an acetylcholine accumulation, which causes symptoms such as diarrhea, sweating, vomiting, small pupils, muscle tremors, increased saliva and tears production and confusion. Other type of pesticides are also common used in agriculture. Glyphosate is a broad‐spectrum systemic herbicide used to kill weeds. It is promoted by the manufacturer as having no risks to human health. We present two patients with a fatal pesticide poisoning. First patient drank OP agent, which was decanted in a non-original bottle. Despite the intensive treatment, including high doses of atropine, and toxogonine, patient died after 6 days due to acute respiratory failure. The second one, tried to commit suicide by drinking 2 glasses of a pesticide called ‘Roundap’ (glyphosate. Short time after admission to a hospital, a myocardial infarction occurred. The patient died the same day, due to a cardiac arrest.

    Askar, A.; Treptow, H.

    1982-01-15

    In the present study information about food poisoning is compared and reviewed. From the viewpoint of a food technologist the toxic substances are represented in four sections: 1. Residues of substances used by plants and animals: pesticides, antibiotics, sexual hormones and psychopharmaces. 2. Environmental contaminants: heavy metals, radionuclides and polycyclic hydrocarbons. 3. Substances developing during the manufacture: food additives, asbest, parts of packing materials, and residual solvents. 4. Substances arising from processing: smoked and roasted food, non enzymatic reaction, oxidized and heated fats and irradiated foods. The mere presence of toxic substances does not make food unsafe or poisonous. Dangerous, because of their toxic or carcinogenic effects are: Pesticides (especially chlorinated organic pesticides), heavy metals (especially lead, mercury and cadmium), polycyclic hydrocarbons (3,4-benzpyren), nitrosamines and vinyl chloride. The other components are only dangerous if they are present in large ammounts. A good and responsible practise of agriculture and food manufacture processes, a watchful and competent official food control and well informed consumers can limit the danger of food poisoning and human health.

  1. Speciation analysis of arsenic compounds in the serum and urine of a patient with acute arsine poisoning

    Full Text Available Arsine is one of the most potent hemolytic agents. It is important to clarify arsine metabolism as well as its chemical interactions with biological components. The aim of the present study was to clarify arsine metabolism by arsenic speciation analysis in serum and urine from an acute poisoning patient with hematuria, anemia, and renal and liver dysfunction. Speciation analysis of arsenics in serum and urine was performed using HPLC-ICP-MS. The total arsenic (T-As concentration in serum was 244.8 μg/l at admission and 97.1 μg/l at discharge. In the speciation analysis, four kinds of As compounds derived from arsine metabolism were detected in serum and urine. The concentration of arsenite (AsIII, arsenate (AsV, monomethylarsonic acid (MMA, and dimethylarsinic acid (DMA in serum at admission were 45.8, 5.2, 17.9 and 9.3 μg/l, respectively. The concentrations of AsIII, AsV, and MMA decreased with biological half time (BHT of 30.1, 43.0, and 96.3 h, respectively. Only DMA was increased at discharge. The urinary AsIII, AsV, MMA and DMA concentrations were 223.0, 12.1, 317.5 and 1053.5 μg/l at discharge, and decreased with BHT of 15.1, 20.8, 14.7, and 16.0 d, respectively. The results indicate that arsine was quickly metabolized to AsIII and subsequently up to DMA, with the result that the toxic effects of inorganic arsenic were added to those of arsine toxicity.

    2007-10-01

    Ciguatera is a form of poisoning that occurs after eating tropical and subtropical ciguatoxic fish. The ciguatoxins are a family of heat stable, lipid soluble cyclic polyether compounds that bind to and open voltage-sensitive Na(+) channels at resting membrane potential, resulting in neural hyperexcitability, as well as swelling of the nodes of Ranvier. The authors describe a 45-year-old man who developed acute gastrointestinal symptoms in Antigua soon after eating red snapper and grouper, potentially "ciguatoxic fish". This was followed by neurological symptoms 24-48 hours later, including temperature reversal (paradoxical dysaesthesia), intense pruritus and increased nociception as a result of a small fibre peripheral neuropathy. The patient's symptoms and small fibre neuropathy improved over a period of 10 months.

    The following aspects are discussed: the public health problems of acute poisoning in China in recent years; the characteristics of acute poisoning; the negative effects of poison cases on the society and economy. The four stages of development of a poison control system in China are: (1) clinical hospital as the only facility used for detoxification; (2) institutes and hospitals of occupational medicine got involved in the program; (3) the traditional model of poison control changed to the modern National Poison Control Center (NPCC), and its network got established and it began to play a key role; (4) establishment of a multi-disciplinary network for dealing with emergencies in which chemical poison control is an important component. Introduction of the operations of the NPCC: the functions of the center are a 24 h hotline service, clinical consultants service, poison identification and diagnosis, laboratory analysis, education for public, training for physicians, coordination of anti-dotes, and the development of a network of poison control centers for dealing with chemical emergencies. The work practice and achievement of NPCC and its network in the field of poison control during the last 3 years is discussed. Lessons from SARS infection: to extend the network, to strengthen multi-disciplinary cooperation, enhance communication between centers, to pay attention to capacity building, to improve reporting systems, and to share resources

    Pesticide induced changes were assessed in thirty two subjects of attempted suicide cases. Among all, the farmers and their families were recorded as most frequently suicide attempting. The values obtained from seven biochemical variables of 29 years old (average age) hospitalized subjects were compared to the same number and age matched normal volunteers. The results revealed major differences in the mean values of the selected parameters. The mean difference calculate; alkaline phosphatase (178.7 mu/l), Bilirubin (7.5 mg/dl), GPT (59.2 mu/l) and glucose (38.6 mg/dl) were higher than the controls, which indicate the hepatotoxicity induced by the pesticides in suicide attempting individuals. Increase in serum creatinine and urea indicated renal malfunction that could be linked with pesticide induced nephrotoxicity among them. (author)

    The availability of antidotes may be considered essential and lifesaving in the management of certain poisonings. Surveys carried out in a number of countries have demonstrated inadequate availability of a variety of poisoning antidotes. The purpose of this study was to determine the availability of antidote stocking at hospitals, based on published guidelines for antidote stocking, and to evaluate the impact of hospital types on the availability of antidotes for the management of acute toxic exposures and poisonings in Malaysia. A questionnaire on the availability of antidotes was sent to all government accident and emergency departments in Malaysia. The list of commonly required antidotes and essential drugs was compiled from published guidelines. Collected data were analysed in SPSS version 16 using descriptive and comparative analysis. The response rate was 59.06%. None of the responding hospitals stocked all of the antidotes on the lists. In relation to hospital type, there was great variability in the availability of antidotes (there were significant differences between hospitals for 13 antidotes). The availabilities of most antidotes were far better in the General Hospitals and the District Hospitals with specialists compared to District Hospitals without specialists. Calcium gluconate, sodium bicarbonate, atropine sulphate, naloxone, flumazenil, vitamin K, and pyridoxine were available at all general hospitals. Atropine sulphate and naloxone were available at all district hospitals with specialists. Most Malaysian government hospitals stocked some important antidotes. Raising awareness of the importance of antidotes by education, regular review of antidote storage, distribution plans, and appropriate legislation might provide solutions. Coordination between Malaysian hospitals and the National Poison Centre at Universiti Sains Malaysia is also important.

    Intentional self-poisonings with seeds from the yellow oleander tree (Thevetia peruviana) are widely reported. Activated charcoal has been suggested to benefit patients with yellow oleander poisoning by reducing absorption and/or facilitating elimination. Two recent randomised controlled trials (RCTs) assessing the efficacy of activated charcoal reported conflicting outcomes in terms of mortality. The effect of activated charcoal on the pharmacokinetics of Thevetia cardenolides has not been assessed. This information may be useful for determining whether further studies are necessary. Serial blood samples were obtained from patients enrolled in a RCT assessing the relative efficacy of single dose (SDAC) and multiple doses (MDAC) of activated charcoal compared to no activated charcoal (NoAC). The concentration of Thevetia cardenolides was estimated using a digoxin immunoassay. The effect of activated charcoal on cardenolide pharmacokinetics was compared between treatment groups using the AUC24, the 24h Mean Residence Time (MRT24), and regression lines obtained from serial concentration points adjusted for exposure. Erratic and prolonged absorption patterns were noted in each patient group. The apparent terminal half-life was highly variable, with a median time of 42.9h. There was a reduction in MRT24 and the apparent terminal half-life estimated from linear regression in patients administered activated charcoal compared to the control group (NoAC). This effect was approximately equal in patients administered MDAC or SDAC. Activated charcoal appears to favourably influence the pharmacokinetic profile of Thevetia cardenolides in patients with acute self-poisoning, which may have clinical benefits. Given the conflicting clinical outcomes noted in previous RCTs, this mechanistic data supports the need for further studies to determine whether a subgroup of patients (eg. those presenting soon after poisoning) will benefit from activated charcoal.

    A cross-sectional study was conducted to investigate the effects of acute and chronic pesticide exposure on the plasma β-glucuronidase enzyme activity among five patients of acute pesticide poisoning in Tengku Ampuan Rahimah Hospital, Klang, 230 farmers in the MADA area, Kedah and 49 fishermen in Setiu, Terengganu. The duration of pesticide exposure among the patients was unknown, but the plasma samples from patients were collected on day one in the hospital. The duration of pesticide exposure among the farmers was between 1 and 45 years. The β-glucuronidase activity was compared with plasma cholinesterase activity in the same individual. The plasma cholinesterase activity was measured using Cholinesterase (PTC) Reagent set kit (Teco Diagnostics, UK) based on colorimetric method, while the plasma β-glucuronidase activity was measured fluorometrically based on β-glucuronidase assay. The plasma cholinesterase activity was significantly reduced (p 0.05). The plasma β-glucuronidase activity among the farmers was significantly elevated (p 0.05). The plasma cholinesterase activity was positively correlated with the plasma β-glucuronidase activity among the farmers (r = 0.205, p 0.05). Thus, plasma β-glucuronidase enzyme activity can be measured as a biomarker for the chronic exposure of pesticide. However, further studies need to be performed to confirm whether plasma β-glucuronidase can be a sensitive biomarker for anticholinesterase pesticide poisoning

    Over the past years there has been an increase in the use of pesticides in developing countries. This study describes pesticide use among small-scale farmers in Uganda and analyses predictors of pesticide poisoning (intoxication) symptoms. A cross-sectional study was conducted using a standardized questionnaire. Some 317 small-scale farmers in two districts in Uganda were interviewed about pesticide use, knowledge and attitude, symptoms of intoxication, personal protective equipment (PPE) and hygiene. The risk of reporting symptoms was analysed using logistic regression analysis. The most frequently used pesticides belonged to WHO class II. The farmers had poor knowledge about pesticide toxicity, and the majority did not use appropriate PPE nor good hygiene when handling pesticides. There was no significant association between the number of times of spraying with pesticides and self-reported symptoms of pesticide poisoning. The only significant association was between blowing and sucking the nozzle of the knapsack sprayer and self-reported symptoms of pesticide intoxication (OR: 2.13. 95% CI: 1.09 - 4.18). Unlike the practice in several other developing countries, small-scale farmers in Uganda do not use the most hazardous pesticides (WHO class 1a and 1b). However use of WHO class II pesticides and those of lower toxicity is seen in combination with inadequate knowledge and practice among the farmers. This poses a danger of acute intoxications, chronic health problems and environmental pollution. Training of farmers in Integrated Pest Management (IPM) methods, use of proper hygiene and personal protective equipment when handling pesticides should be promoted.

In this prospective study, the IMA levels of 100 patients with CO poisoning and 50 control individuals were compared. In addition, the IMA and COHB levels were analyzed according to absence or presence CNFs in patients with CO poisoning. The levels of IMA (mg/dL on admittance, and during the 1st hour and 3rd hour, in patients with CO poisoning (49.90 ± 35.43, 30.21 ± 14.81, and 21.87 ± 6.03 were significantly higher, compared with the control individuals (17.30 ± 2.88. The levels of IMA in the 6th hour were not higher compared with control individuals. The levels of IMA on admittance, and during the 1st hour, 3rd hour, and 6th hour, and COHB (% levels in patients who had CNFs were higher compared with IMA levels and COHB levels in patients who had no CNFs (p < 0.001. However, when the multivariate model was created, it was observed that IMA level on admittance was a poor indicator for prediction of CNFs (odds ratio = 1.05; 95% confidence interval, 1.01–1.08. We therefore concluded that serum IMA levels could be helpful in the diagnosis of CO poisoning. However, we believe that IMA levels cannot be used to predict which patients will develop CNFs due to CO poisoning.

    The employment of a purpose-made capillary electrophoresis (CE) instrument with capacitively coupled contactless conductivity detection (C 4 D) as a simple and cost-effective solution for clinical screening of paraquat in plasma samples for early-stage diagnosis of acute herbicide poisoning is reported. Paraquat was determined using an electrolyte composed of 10mM histidine adjusted to pH 4 with acetic acid. A detection limit of 0.5mg/L was achieved. Good agreement between results from CE-C 4 D and the confirmation method (HPLC-UV) was obtained, with relative errors for the two pairs of data better than 20% for 31 samples taken from paraquat-intoxicated patients. The results were used by medical doctors for identification and prognosis of acute paraquat poisoning cases. The objective of the work is the deployment of the developed approach in rural areas in Vietnam as a low-cost solution to reduce the mortality rate due to accidental or suicidal ingestion of paraquat.

    Endosulfan, an organochlorine (OC) insecticide, is a widely used agricultural pesticide, despite its life threatening toxic effects. In this review, the pharmacokinetics of endosulfan, mechanism of endosulfan toxicity, clinical presentations and management, histopathological findings, and toxicological analysis are described, in addition to its environmental toxicity. The toxic effects of endosulfan can affect many organs and systems presenting in a wide array of signs and symptoms. Although termed a restricted OC-classed pesticide, it continues to be used, especially in the developing world, owing to its beneficial effects on agriculture. Several cases of endosulfan poisoning have been reported from different regions of the world. Whether accidental or intentional, endosulfan ingestion proves to be fatal unless immediate, aggressive treatment is initiated. Management is mainly supportive as no antidote exists for endosulfan poisoning as yet. The use of endosulfan needs to be strictly regulated and eventually banned worldwide altogether to lower the current morbidity and mortality resulting from this pesticide. Additionally, monitoring biological samples, using non-invasive techniques such as breast milk sampling, can provide an effective method of observing the elimination of this environmentally persistent organic pollutant from the general population.

    Full Text Available BACKGROUND Yellow oleander (Cascabela thevetia is a poisonous plant that is widely found in India. All parts of the C. thevetia plant are toxic to humans as they contain cardiac glycosides. MATERIALS AND METHODS 100 patients with alleged history of yellow oleander seed poisoning who came to Kanyakumari Government Medical College Hospital during the period of 2013-16 were enrolled in this study. Patients presenting with multiple poison consumption and those with previous history of heart disease were excluded from the study. A detailed history of the number of seeds consumed, the time of consumption, detailed clinical assessment, routine blood investigations and a 12-lead ECG were recorded. ECG was recorded at the time of admission and every 12th hourly to detect any cardiac arrhythmias. RESULTS Most symptomatic patients had conduction defects affecting the SA node, the AV node or both. Patients showing cardiac arrhythmias had significantly higher mean serum potassium concentrations ranging from 4.5-5.2 mEq/L. Yellow oleander seed poisoning is common among young females (56%. There is a poor correlation between the number of seeds ingested and the severity of cardiotoxicity. Arrhythmias has occurred after ingestion of one or two seeds; some patients are asymptomatic even after consuming five or more seeds without requiring specialised treatments. This could be explained on the basis that crushed seeds are more dangerous than whole seeds. CONCLUSION Most of these young previously healthy patients had conduction defects affecting the SA or AV nodes. Relatively, few had the atrial tachyarrhythmias or ventricular ectopic beats that are typical of digoxin poisoning. Yellow oleander induced arrhythmias were associated with high serum potassium levels when compared to patient without arrhythmias.

    Previous studies have demonstrated that acute poisoning from exposure to organophosphate (OP) pesticides in agricultural workers causes adverse health effects. However, neuropsychological and cognitive effects of chronic occupational exposure to OP pesticides remain controversial. To identify, evaluate, and systematize existing evidence regarding chronic exposure to OP pesticides and neuropsychological effects in farmworkers. Using the PubMed search engine, a systematic review process was implemented and replicated according to the PRISMA statement. Eligibility criteria included workers over 18 years of age exposed to OP pesticides as well as assessment of neuropsychological and cognitive functioning. Search terms were in English and Spanish languages and included organophosphate and workers. Of the search results, 33 of 1,256 articles meet eligibility criteria. Twenty-four studies found an association between chronic occupational exposure to OP pesticides and low neuropsychological performance in workers. We classified nine of the studies to have study design limitations. Studies indicated occupational exposure to OP pesticides is linked to difficulties in executive functions, psychomotor speed, verbal, memory, attention, processing speed, visual-spatial functioning, and coordination. Nine studies find no relationship between OP pesticides exposure and neuropsychological performance. Overall, evidence suggests an association between chronic occupational exposure to OP pesticides and neuropsychological effects. However, there is no consensus about the specific cognitive skills affected.

    Adequate consumption of fruits and vegetables is a part of recommendations for a healthy diet. The aim of the present study was to assess acute cumulative dietary exposure to organophosphorus and carbamate pesticides via fruit and vegetable consumption by the population of schoolchildren aged 11-12 years and the level of risk for their health. Cumulative probabilistic risk assessment methodology with the index compound approach was applied. Slovenia, primary schools. Schoolchildren (n 1145) from thirty-one primary schools in Slovenia. Children were part of the PRO GREENS study 2009/10 which assessed 11-year-olds' consumption of fruit and vegetables in ten European countries. The cumulative acute exposure amounted to 8.3 (95% CI 7.7, 10.6) % of the acute reference dose (ARfD) for acephate as index compound (100 µg/kg body weight per d) at the 99.9th percentile for daily intake and to 4.5 (95% CI 3.5, 4.7) % of the ARfD at the 99.9th percentile for intakes during school time and at lunch. Apples, bananas, oranges and lettuce contributed most to the total acute pesticides intake. The estimations showed that acute dietary exposure to organophosphorus and carbamate pesticides is not a health concern for schoolchildren with the assessed dietary patterns of fruit and vegetable consumption.

  8. Copper sulphate poisoning in horses

    In the archives of the Clinic for Internal Diseases of Domestic Animals at the Veterinary Faculty of Zagreb University some thirty cases of horse disease diagnosed as copper sulphate poisoning were noted. The data correspond in many respects to the clinical findings of copper sulphate poisoning in other domestic animals. A series of experimental horse poisonings were undertaken in order to determine the toxicity of copper sulphate. The research results are as follows: Horses are sensitive to copper sulphate. Even a single application of 0.125 g/kg body weight in 1% concentration by means of incubation into the stomach causes stomach and gut disturbances and other poisoning symptoms. Poisoning occurs in two types: acute and chronic. The former appears after one to three applications of copper sulphate solution and is characterized by gastroenteritis, haemolysis, jaundice and haemoglobinuria with signs of consecutive damage of kidney, liver and other organs. The disease, from the first application to death lasts for two weeks. Chronic poisoning is caused by ingestion of dry copper sulphate in food (1% solution dried on hay or clover) for two or more months. There are chronic disturbances of stomach and gut and loss of weight, and consecutive (three to four) haemolytic crises similar to those of acute poisoning. From the beginning of poisoning to death six or more months can elapse.

    Following a line of work we studied 1,140 acute poisoning (AP) attended at the Internal Medicine Emergency Department at 12 de Octubre Hospital, Madrid, in 1997. The incidence increased up to 157/100,000 inhabitants. Mean age was 36 years (SD: 15 y), median, 32 years. Self-inflicted AP: 1,052 cases (92%); the suicide attempt was the most common type (509, 48%). Among males, the alcoholic intoxication (332, 59%) predominated. Among accidental AP (88 cases), 90% occurred at home. Poisons: drugs. Drugs were used for 78% of suicide attempts. The relative incidence of benzodiazepines increased (47%) and that of antidepressive drugs decreased (11%). A remarkable increase in the "other drugs" group was noted, as well as the association of drugs and non-drugs (10%). Alcohol use increased significantly (249 cases more than in 1994), as well as drugs although to a lesser extent, breaking the trend observed in the last few years. Cocaine is now the most common (among women heroin is still the leading cause); 5 AP were caused by synthesis drugs (extasis, MDMA) and an increase was observed with "other drugs". suicide attempts: depression (30%) and previous attempts (19%); ethylism: alcoholism (40%); AP with other drugs: drug abuse (52%). Admitted to ICU: 1.4%. The mortality rate decreased to 0.08%.

    Sodium dimercaptopropanesulphonate (DMPS) and sodium dimercaptosuccinate (DMS) were discovered to be effective antidotes for acute poisoning of insecticides SCD [sodium ammonium dimethyl-2-(propane-1,3-dithiosulfate) monohydrate], nereistoxin (4-N,N-dimethylamino-1,2-dithiolane) and cartap (dihydronereistoxin dicarbamate). In mice, DMPS (250 mg/kg) or DMS (1000 mg/kg) ip 20 min before SCD increased LD50 of ig SCD from 97 to 374 or 251 mg/kg, respectively. The prophylactic effect of DMPS was better than that of DMS. Administration of DMPS prior to cartap increased LD50 of ig cartap from 130 to 375 mg/kg. The therapeutic effect of DMPS was also demonstrated in SCD-poisoned conscious rabbits. DMPS 62.5 mg/kg or DMS 500 mg/kg iv completely antagonized the neuromuscular blockade and respiratory depression caused by SCD, nereistoxin and cartap in anesthetized rabbits. The antagonism of SCD-induced neuromuscular blockade by cysteine (400 mg/kg, iv) was less effective and of shorter duration than that by DMPS and DMS. Dimercaprol 50 mg/kg im showed little effect on SCD-induced paralysis. The antagonistic actions of sulfhydryl compounds on neuromuscular blockade induced by these insecticides probably belong to chemical antagonism.

    Benzodiazepines are among the most frequently ingested drugs in self-poisonings. Elderly may be at greater risk compared with younger individuals due to impaired metabolism and increased sensitivity to benzodiazepines. The aim of this study was to assess toxicity of benzodiazepines in elderly attempted suicide. A retrospective study of consecutive presentations to hospital after self-poisoning with benzodiazepines was done. Collected data consisted of patient's characteristics (age, gender), benzodiazepine ingested with its blood concentrations at admission, clinical findings including vital signs and Glasgow coma score, routine blood chemistry, complications of poisoning, details of management, length of hospital stay and outcome. According the age, patients are classified as young (15-40-year old), middle aged (41-65-year old) and elderly (older than 65). During a 2-year observational period 387 patients were admitted because of pure benzodiazepine poisoning. The most frequently ingested drug was bromazepam, the second was diazepam. The incidence of coma was significantly higher, and the length of hospital stay significantly longer in elderly. Respiratory failure and aspiration pneumonia occurred more frequently in old age. Also, flumazenil was more frequently required in the group of elderly patients. Massive benzodiazepines overdose in elderly may be associated with a significant morbidity, including deep coma with aspiration pneumonia, respiratory failure, and even death. Flumazenil is indicated more often to reduce CNS depression and prevent complications of prolonged unconsciousness, but supportive treatment and proper airway management of comatose patients is the mainstay of the treatment of acute benzodiazepine poisoning.

  4. Effect of acute pesticide exposure on bee spatial working memory using an analogue of the radial-arm maze

    Samuelson, Elizabeth E. W.; Chen-Wishart, Zachary P.; Gill, Richard J.; Leadbeater, Ellouise

    2016-12-01

    Pesticides, including neonicotinoids, typically target pest insects by being neurotoxic. Inadvertent exposure to foraging insect pollinators is usually sub-lethal, but may affect cognition. One cognitive trait, spatial working memory, may be important in avoiding previously-visited flowers and other spatial tasks such as navigation. To test this, we investigated the effect of acute thiamethoxam exposure on spatial working memory in the bumblebee Bombus terrestris, using an adaptation of the radial-arm maze (RAM). We first demonstrated that bumblebees use spatial working memory to solve the RAM by showing that untreated bees performed significantly better than would be expected if choices were random or governed by stereotyped visitation rules. We then exposed bees to either a high sub-lethal positive control thiamethoxam dose (2.5 ng-1 bee), or one of two low doses (0.377 or 0.091 ng-1) based on estimated field-realistic exposure. The high dose caused bees to make more and earlier spatial memory errors and take longer to complete the task than unexposed bees. For the low doses, the negative effects were smaller but statistically significant, and dependent on bee size. The spatial working memory impairment shown here has the potential to harm bees exposed to thiamethoxam, through possible impacts on foraging efficiency or homing.

    Development of an acute oral toxicity test with a terrestrial-phase amphibian was considered necessary to remove the uncertainty within the field of agrochemical risk assessments. The bullfrog (Lithobates catesbeianus) was selected for use as it is a representative of the family Ranidae and historically this species has been used as an amphibian test model species. Prior to definitive study, oral gavage methods were developed with fenthion and tetraethyl pyrophosphate. Dimethoate and malathion were subsequently tested with both male and female juvenile bullfrogs in comprehensive acute oral median lethal dose (LD50) studies. Juvenile bullfrogs were administered a single dose of the test article via oral gavage of a single gelatin capsule of dimethoate technical (dimethoate) or neat liquid Fyfanon ® Technical (synonym malathion), returned to their respective aquaria, and monitored for survival for 14 d. The primary endpoint was mortality, whereas behavioral responses, food consumption, body weight, and snout-vent length (SVL) were used to evaluate indications of sublethal toxicity (secondary endpoints). Acute oral LD50 values (95% fiducial interval) for dimethoate were 1459 (1176-1810, males) and 1528 (1275-1831, females), and for malathion they were 1829 (1480-2259, males) and 1672 (1280-2183, females) mg active substance/kg body weight, respectively. Based on the results of these studies, the methodology for the acute oral gavage administration of test items to terrestrial-phase amphibians was demonstrated as being a practical method of providing data for risk assessments.

    Full Text Available Bees are potential pollinators of wide variety of crops. The European dark bee, Apis mellifera mellifera (L. is widely used for crop pollination. However, pesticide usage in modern agriculture has threatened the plant-bee pollinator interaction. There is lack of data regarding lethal time, insecticide concentration and poisoning symptoms, especially for formulated insecticides that are widely used in insect management. This study shows that the intrinsic toxicity of insecticides (LC50 to A. mellifera mellifera (L. was in the following order: imidacloprid (0.0070 > fipronil (0.0125 > indoxacarb (0.0266> cypermethrin (0.0370 > dimethoate (0.0385. The lethal time (LT50 values (h in the ascending order of toxicity of insecticides were as follows: fipronil (6.56, cypermethrin (6.69, dimethoate (8.00, imidacloprid (9.85 and indoxacarb (13.45. Distinct poisoning symptoms observed in A. mellifera mellifera were extended proboscis, expanded wings, unhooked wings, extended legs and twisted bodies, defecation on cage covers, sting in release-out position and anus with excreta. All the tested pesticides are harmful to the honey bee except azadirachtin. The tested pesticides exhibited different poisoning symptoms in bees, which could be useful for beekeepers in identifying the cause of colony mortality. In conclusion, the pesticide toxicological research on bees is an important safety aspect for beneficial organisms. This study reveals a realistic acute toxicity in the field of commonly used insecticides. The information is important for insecticide selection in order to minimize direct killing of foraging honey bees while maintaining effective management of crop pests.

    Organophosphorous (OP) compounds have been used as pesticides and chemical warfare nerve agents. Despite administration of well known antidotes (atropine and oximes), morbidity and mortality of OP poisoning were still high. Besides, oximes are very expensive and not available in most developing countries. It was thus aimed to study the effects of cheap available antidotes; sodium bicarbonate and magnesium sulfate in OP poisoning. In addition to the standard antidotal treatment, out of 117 patients (63M, 47F) aged 25.2 ± 9.5 years with moderate to severe acute OP pesticide poisoning 59 were given sodium bicarbonate 5 mEq/kg in 60 min. followed by 5-6 mEq/kg/day to obtain arterial blood pH of 7.45 to 7.55. Arterial blood pH increased significantly (p less than 0.01) to 7.48 ± 0.05 compared to the controls (7.32 ± 0.06). Morbidity based on hospitalization days reduced significantly (p less than 0.05) from 5.62 ± 3.4 in the controls to 3.1 ± 2.6 days in the sodium bicarbonate group. Total atropine dose was also significantly (p less than 0.05) lower in the test group. Mortality was lower, but not significantly due to the low numbers (5 and 2 of the controls and test group, respectively). Sodium bicarbonate appeared to be effective and could be added to the treatment regime of OP poisoning. Magnesium sulfate was administered four gram intravenously only for the first 24 hr of hospitalization day for the patients with moderate to severe OP poisoning in a pilot study. The results were promising and thus further investigations are continued.(author)

    Emergency Medical Services (EMS) were founded by the government to perform tasks aimed at providing people with help in life-threatening conditions. The system comprises two constituent parts. The first one is public administrative bodies which are to organise, plan, coordinate and supervise the completion of the tasks. The other constituent is EMS units which keep people, resources and units in readiness. Supportive services, which include: the State Fire Service (SFS) and the National Firefighting and Rescue System (NFRS), are of great importance for EMS because they are eligible for providing acute medical care (professional first aid). Acute medical care covers actions performed by rescue workers to help people in life-threatening conditions. Rescue workers provide acute medical care in situations when EMS are not present on the spot and the injured party can be accessed only with the use of professional equipment by trained workers of NFRS. Whenever necessary, workers of supportive services can assist paramedics' actions. Cooperation of all units of EMS and NFRS is very important for rescue operations in the integrated rescue system. Time is a key aspect in delivering first aid to a person in life-threatening conditions. Fast and efficient first aid given by the accident's witness, as well as acute medical care performed by a rescue worker can prevent death and minimise negative effects of an injury or intoxication. It is essential that people delivering first aid and acute medical care should act according to acknowledged and standardised procedures because only in this way can the process of decision making be sped up and consequently, the number of possible complications following accidents decreased. The present paper presents an analysis of legal regulations concerning the management of chemical burn and inhalant intoxication in acute medical care procedures of the State Fire Service. It was observed that the procedures for rescue workers entitled to

    Full Text Available Introduction: Carbon monoxide is known as the silent killer, being colorless, odourless, and tasteless. Initially non-irritating, it is very difficult for people to detect Carbon monoxide is a product of incomplete combustion of organic matter due to insufficient oxygen supply that prevents complete oxidation of carbon to C02. During World War II, Nazis used gas vans to kill an estimated over 700,000 prisoners by carbon monoxide poisoning. This method was also used in the gas chambers ofseveral death camps. The true number of incidents of carbon monoxide poisoning is unknown, since many non-lethal exposures go undetected From the available data, carbon monoxide poisoning is the most common cause of injury and death due to poisoning worldwide. Clinical features and management: The signs of carbon monoxide poisoning vary with concentration and length of exposure. Subtle cardiovascular or neurobehavioural effects occur at low concentration. The onset of chronic poisoning is usually insidious and easily mistaken for viral prodrome, depression, or gastroenteritis in children. The classic sign of carbon monoxide poisoning which is actually more often seen in the dead than the living is appearing red-cheeked and healthy. Cherry pink colour develops in nails, skin and mucosa. In acute poisoning, common abnormalities of posture and tone are cogwheel rigidity, opisthotonus, spasticity or flaccidity and seizures. Retinal haemorrhages and the classic cherry red skin colour are seldom seen. Different people andpopulations may have different carbon monoxide tolerance levels. On average, exposures at 100ppm or greater is dangerous to human health. Treatment and prevention: The mainstay of treatment is 100% oxygen administration until the COHb level is normal When the patient is stable enough to be transported, hyperbaric oxygen (HBOT should be considered This treatment is safe and well tolerated Public education about the danger of carbon monoxide, with

A citopatologia e histopatologia da medula óssea dos quatro bovinos intoxicados revelaram acentuada diminuição no número de células hematopoéticas das três linhagens medulares, caracterizando insuficiência medular por aplasia; conclui-se que apenas eventos da hemostasia primária devidos a trombocitopenia são responsáveis pelas hemorragias. Na hemocultura de três dos bovinos intoxicados houve crescimento de Klebsiella oxytoca, Staphylococcus hyicus e Staphylococcus aureus, indicando que a septicemia, facilitada pela neutropenia, pode ter participação na causa da morte de bovinos na intoxicação aguda pela ingestão de P. aquilinum. Aspectos adicionais de interesse na reprodução da intoxicação aguda por samambaia em bovinos deste relato incluem o desenvolvimento de hematúria na doença aguda e a apresentação da chamada forma laríngea da doença.This experiment was design to address the following points in relation to the acute poisoning by bracken fern (Pteridium aquilinum in cattle: 1 the severity of the thrombocytopenia in different stages of the intoxication and its relationship to possible deficits in the secondary hemostasis, 2 the relationship between neutropenia and the morphological signs of septicemia occasionally found at necropsy, and 3 the mechanism of anemia and its relationship with blood loss, medium life of erythrocytes and the progress of the disease. The fresh green upper parts of P. aquilinum were fed to four mixed breed calves with average age of 18 months and weights ranging from 190 to 215 kg. A calf of similar age and weight was kept together with the other four under the same conditions, except for the ingestion of P. aquilinum. The four fern-fed calves died with typical features of acute bracken fern poisoning after being fed with the plant for 53-58 days daily doses of 8.0, 8

    2016-01-01

    Full Text Available Background/Aim. Benzodiazepines are among the most frequently ingested drugs in self-poisonings. Elderly may be at greater risk compared with younger individuals due to impaired metabolism and increased sensitivity to benzodiazepines. The aim of this study was to assess toxicity of benzodiazepines in elderly attempted suicide. Methods. A retrospective study of consecutive presentations to hospital after self-poisoning with benzodiazepines was done. Collected data consisted of patient's characteristics (age, gender, benzodiazepine ingested with its blood concentrations at admission, clinical findings including vital signs and Glasgow coma score, routine blood chemistry, complications of poisoning, details of management, length of hospital stay and outcome. According the age, patients are classified as young (15-40-year old, middle aged (41-65-year old and elderly (older than 65. Results. During a 2-year observational period 387 patients were admitted because of pure benzodiazepine poisoning. The most frequently ingested drug was bromazepam, the second was diazepam. The incidence of coma was significantly higher, and the length of hospital stay significantly longer in elderly. Respiratory failure and aspiration pneumonia occurred more frequently in old age. Also, flumazenil was more frequently required in the group of elderly patients. Conclusion. Massive benzodiazepines overdose in elderly may be associated with a significant morbidity, including deep coma with aspiration pneumonia, respiratory failure, and even death. Flumazenil is indicated more often to reduce CNS depression and prevent complications of prolonged unconsciousness, but supportive treatment and proper airway management of comatose patients is the mainstay of the treatment of acute benzodiazepine poisoning.

    Cases of thallium poisoning are rare and neuropsychological assessment has only been reported in detail in one other case. In the case reported here, neuropsychological assessments were carried out three, 12, and 54 months after diagnosis of thallium poisoning in a man who had acutely shown a number of neurological signs including confusion and disorientation and generalised slowing of EEG which was more prominent on the left. Evidence suggested that he had been exposed to thallium over a period of weeks. Neuropsychological assessment indicated an unexpected weakness in verbal abilities which persisted. This finding is consistent with the only other published case report which details neuropsychological effects after a single large dose of thallium and which also found a lateralised impairment.

  17. Fatal aluminium phosphide poisoning

    Directory of Open Access Journals (Sweden)

    Meena Mahesh Chand

    2015-06-01

    Full Text Available Aluminium phosphide (AlP is a cheap solid fumigant and a highly toxic pesticide which is commonly used for grain preservation. AlP has currently aroused interest with a rising number of cases in the past four decades due to increased use for agricultural and non-agricultural purposes. Its easy availability in the markets has increased also its misuse for committing suicide. Phosphine inhibits cellular oxygen utilization and can induce lipid peroxidation. Poisoning with AlP has often occurred in attempts to commit suicide, and that more often in adults than in teenagers. This is a case of suicidal consumption of aluminium phosphide by a 32-year-old young medical anesthetist. Toxicological analyses detected aluminium phosphide. We believe that free access of celphos tablets in grain markets should be prohibited by law.

    To observe the changes in the expression of connective tissue growth factor (CTGF), type I collagen (Col I), and type III collagen (Col III) among the rats with acute paraquat (PQ) poisoning and the intervention effect of pyrrolidine dithiocarbamate (PDTC) on their expression, and to investigate the mechanism of PQ-induced pulmonary fibrosis and the intervention effect of PDTC on the disease. Sprague-Dawley rats were randomly divided into control group (n = 6), PQ group (n = 36), and PQ + PDTC group (n = 36). The PQ group and PQ + PDTC group were given a single dose of saline-diluted PQ (80 mg/kg) by gavage; 2 h later, the PQ + PDTC group was intraperitoneally injected with a single dose of PDTC (100 mg/kg), and the PQ group was intraperitoneally injected with the same amount of saline. The control group was given saline (1 ml/kg) by gavage and was intraperitoneally injected with the same amount of saline 2h later. At 1, 3, 7, 14, 25, and 56 days after operation, the protein expression of CTGF was evaluated by Western blot; the mRNA expression of CTGF, Col I, and Col III was analyzed by real-time quantitative PCR; the content of hydroxyproline in lung tissue was measured, and the pathological changes of lung tissue of the poisoned rats were observed. The protein expression of CTGF in the PQ group increased as the time went on, slowly from the 3rd to the 14th day and rapidly from the 28th to the 56th day, significantly higher than that in the control group at each time point (P < 0.05 or P < 0.01). The mRNA expression of CTGF in the PQ group began to rise markedly on the 1st day, increased rapidly from the 3rd to the 14th day, and remained at a relatively high level from the 28th to the 56th day, significantly higher than that in the control group at each time point (P < 0.01). The mRNA expression of Col I in the PQ group changed little on the 1st and 3rd day, increased slightly on the 7th day, and increased greatly from the 14th to the 56th day, significantly

    European legislation requires reporting from Member States on acute poisoning incidents involving pesticides. However, standard rules for data collection and reporting have not yet been set out. The new categorization system presented in this paper is aimed at enabling Member States to gather comparable data and provide standard reporting on pesticide poisoning exposures. European Regulations providing separate official categorization of biocidal and plant protection pesticides, were used as a basis to build up a unified pesticide categorization and coding system. Data on selected pesticide exposures collected by Poison Control Centres in six EU countries were reviewed, categorized and reported according to the proposed system. The resulting pesticide categorization system has two dimensions. The first part identifies the main category of use, i.e. biocide/plant protection pesticide/unknown, and the secondary category of use, e.g. Rodenticides, Insecticides and acaricides. The second part of the system is organized into two levels: level one identifies chemical grouping, e.g. Coumarins, Pyrethrins/pyrethroids, while level two identifies the active compound by using its Chemical Abstract Service Registry Number. The system was used to provide a unified categorization to compare exposures to plant protection and biocidal Rodenticides and Pyrethrins/pyrethroids Insecticides and acaricides identified by six EU member states. The developed pesticide categorization system was successfully applied to data extracted from different databases and was able to make the required information comparable. The data reported filling in common templates containing a pre-ordinate list of active compounds categorized according the proposed system, highlighted different capabilities in data collection and recording, showing that some of the collaborating centres were not able to distinguish between main categories of pesticide products or provide information on active compounds.

    BACKGROUND: Between 1950 and 1995 suicide rates in Sri Lanka increased 8-fold to a peak of 47 per 100,000 in 1995. By 2005, rates had halved. We investigated whether Sri Lanka's regulatory controls on the import and sale of pesticides that are particularly toxic to humans were responsible...... with these declines. CONCLUSION: These data indicate that in countries where pesticides are commonly used in acts of self-poisoning, import controls on the most toxic pesticides may have a favourable impact on suicide. In Asia, there are an estimated 300,000 deaths from pesticide self-poisoning annually. National...

    In recent years, industrial employment of cadmium has increased considerably. Cadmium is now present in the environment and has caused acute and chronic poisoning. Inhalation of cadmium vapor or dust causes pulmonary damage while the kidney is the critical organ in absorption of cadmium. The element accumulates in the kidney and causes tubular damage or 200 ppm in the renal cortex. In animal experiments, cadmium may cause raised blood pressure, sterility and malignant tumors. On account of the pronounced tendency of cadmium to accumulate and its toxicity, it is important to trace sources and to reduce exposure of the population. 62 references.

    Full Text Available BACKGROUND The state of Andhra Pradesh, particularly the coastal districts are an area of intensive agricultural production. Pesticide use is high, and the state has one of the highest reported rates of pesticide poisoning in India. The resources for treating this number of cases in government hospitals are limited and likely to have an impact on patient outcome. The present study was carried out in one such hospital of the state. Amongst these pesticides, insecticides constitute an important group, and organophosphorus compounds are possibly the insecticides widely used, all over the world. MATERIALS AND METHODS Hundred patients of pesticide poisoning admitted into the medical ward of Government General Hospital, Kakinada during the period of August 2010 to July 2014 were studied. Detailed history was taken in each case from patient and attendants. A meticulous physical examination was done on each of them at the time of admission. The diagnosis of poisoning was suspected from the characteristic garlic and kerosene like odour, characteristic signs and symptoms of poisoning and corroborative evidence collected in the form of packets or containers obtained from the site by family members or bystanders. RESULTS Out of the 14 patients who died, 11 died due to organophosphate poisoning, 2 patients died due to organochlorine poisoning and 1 patient died due to herbicide poisoning. Out of the 11 patients who expired due to organophosphate poisoning, 10 patients had pseudocholinesterase value ≤1 unit/mL. The remaining one (1 patient who died, had a pseudocholinesterase value of 2.2 units/mL. Of the 11 patients who died due to organophosphate poisoning, Monocrotophos recorded highest number of deaths (6 cases, followed by dimethoate, which was responsible for 2 deaths. Methyl parathion, Profenophos and Chlorpyriphos caused 1 death each. An organochlorine compound, Endosulfan caused 2 deaths. Paraquat, a herbicide was responsible for 1 death

    We describe a case of a 43-yr-old female with severe multiorgan injury after accidental poisoning with Colchicum autumnale, which was mistaken for wild garlic (Allium ursinum). Both plants grow on damp meadows and can be confused in the spring when both plants have leaves but no blossoms. The autumn crocus contains colchicine, which inhibits cellular division. Treatment consisted of supportive care, antibiotic therapy, and granulocyte-directed growth factor. The patient was discharged from the hospital after three weeks. Three years after recovery from the acute poisoning, the patient continued to complain of muscle weakness and intermittent episodes of hair loss.

    2011-01-01

    Alcohol-based hand sanitizers (ABHSs) have been widely used in homes, workplaces and schools to prevent the spread of infectious diseases. We report a young child unintentionally ingested ABHS at a school, resulting in intoxication. The child was a 6-year-old girl who had been brought to the emergency department (ED) for hypothermia, altered mental status (AMS), periods of hypoventilation, hypothermia and vomiting. Computed tomography of her head revealed nothing abnormal in intracranial pathology. Urine drug screening was negative. Alcohol level was 205 mg/dL on admission. Other abnormal values included potassium of 2.8 mEq/L, osmolality of 340 mOsm/kg and no hypoglycemia. Further investigation revealed that the patient had gone frequently to the class restroom for ingestion of unknown quantities of ABHSs during the day. The patient was admitted for one day for intravenous fluid hydration and close observation of her mental status. The patient was discharged from the hospital the next day without any complications. Despite the large safety margin of ABHSs, emergency physicians need to be aware of the potential risk of ingestion of a large amount of such products in children and consider it in the assessment and management of school-age children with acute AMS.

    Alcohol-based hand sanitizers have become widely available because of widespread usage in schools, hospitals, and workplaces and by consumers. We report what we believe is the first unintentional ingestion in a small child producing significant intoxication. A 4-year-old 14-kg girl was brought to the emergency department with altered mental status after a history of ingesting an alcohol-based hand sanitizer. Physical examination revealed an obtunded child with periods of hypoventilation and a hematoma in the central portion of her forehead from a fall at home that occurred after the ingestion. Abnormal vital signs included a heart rate of 139 beats/min and temperature of 96.3 degrees F, decreasing to 93.6 degrees F. Abnormal laboratory values consisted of potassium of 2.6 mEq/L and a serum alcohol of 243 mg/dL. A computed tomography scan of her brain without contrast showed no acute intracranial abnormality. A urine drug screen for common drugs of abuse was reported as negative. The child was intubated, placed on mechanical ventilation, and admitted for medical care. She recovered over the next day without sequelae. As with other potentially toxic products, we would recommend caution and direct supervision of use when this product is available to young children.

    Pesticides are frequently used substances worldwide, even when the use of some of them is forbidden due to the recognized adverse effect they have on the health of not only the people who apply the pesticides, but also of those that consume the contaminated products. The objectives of this study were to know the health issues of farm workers chronically exposed to pesticides, to evaluate possible damage at genetic level, as well as to explore some hepatic, renal, and hematological alterations. A transversal comparative study was performed between 2 groups, one composed of 25 farm workers engaged in pesticide spraying, and a control group of 21 workers not exposed to pesticides; both groups belonged to the Nextipac community in Jalisco, Mexico. Each member of both groups underwent a full medical history. Blood samples were taken from all farm workers in order to obtain a complete blood count and chemistry, clinical chemistry, lipid profile, liver and kidney function tests, erythrocyte cholinesterase quantification, lipid peroxidation profile, and free DNA fragment quantification. For the information analysis, central tendency and dispersion measurements were registered. In order to know the differences between groups, a cluster multivariate method was used, as well as prevalence reasons. The most used pesticides were mainly organophosphates, triazines and organochlorine compounds. The exposed group showed acute poisoning (20% of the cases) and diverse alterations of the digestive, neurological, respiratory, circulatory, dermatological, renal, and reproductive system probably associated to pesticide exposure. More importantly, they presented free DNA fragments in plasma (90.8 vs 49.05 ng/mL) as well as a higher level of lipid peroxidation (41.85 vs. 31.91 nmol/mL) in comparison with those data from unexposed farm workers. These results suggest that there exist health hazards for those farm workers exposed to pesticides, at organic and cellular levels.

  16. Comparison of two pre-exposure treatment regimens in acute organophosphate (paraoxon) poisoning in rats: Tiapride vs. pyridostigmine

    Recently, the FDA approved the medical use of oral pyridostigmine as prophylactic treatment of possible nerve agent exposure: the concept is to block the cholinesterase transitorily using the carbamate (pyridostigmine) in order to deny access to the active site of the enzyme to the irreversible inhibitor (nerve agent) on subsequent exposure. We have shown previously that tiapride is in vitro a weak inhibitor of acetylcholinesterase and that in rats administration of tiapride before the organophosphate paraoxon significantly decreases mortality. The purpose of the present study was to compare tiapride- and pyridostigmine-based pretreatment strategies, either alone or in combination with pralidoxime reactivation, by using a prospective, non-blinded study in a rat model of acute high-dose paraoxon exposure. Groups 1-6 received 1 μMol paraoxon (∼ LD 75 ) groups 2-6 received in addition: G 2 50 μMol tiapride 30 min before paraoxon; G 3 50 μMol tiapride 30 min before paraoxon and 50 μMol pralidoxime 1 min after paraoxon; G 4 1 μMol pyridostigmine 30 min before paraoxon; G 5 1 μMol pyridostigmine 30 min before paraoxon and 50 μMol pralidoxime 1 min after paraoxon; G 6 50 μMol pralidoxime 1 min after paraoxon; Mortality data were compared using Kaplan-Meier plots and logrank tests. Mortality is statistically significantly influenced by all treatment strategies. Tiapride pretreatment followed by pralidoxime treatment (G 3 ) is aux par with pyridostigmine pretreatment followed by pralidoxime treatment (G 5 ). Tiapride pretreatment only (G 2 ) is inferior to pyridostigmine pretreatment only (G 4 ). The best results are achieved with pyridostigmine pretreatment only or pralidoxime treatment only (G 4 and G 6 )

    In 2011, German hospitals treated approximately 205 000 patients suffering from acute poisoning. Change is seen over time both in the types of poisoning that occur and in the indications for specific treatment. This article is based on a selective review of the literature, with special attention to the health reports of the German federal government, the annual reports of the GIZ-Nord Poisons Center (the poison information center for the four northwestern states of Germany, i.e. Bremen, Hamburg, Lower Saxony and Schleswig-Holstein), and the recommendations of international medical associations. From 1996 to 2011, the GIZ-Nord Poisons Center answered more than 450 000 inquiries, most of which involved exposures to medical drugs, chemicals, plants, foods, or cosmetics. Poisoning was clinically manifest in only a fraction of these cases. Ethanol intoxication is the commonest type of acute poisoning and suicide by medical drug overdose is the commonest type of suicide by poisoning. Death from acute poisoning is most commonly the result of either smoke inhalation or illegal drug use. Severe poisoning is only rarely due to the ingestion of chemicals (particularly detergents and cleaning products), cosmetics, or plant matter. Medical procedures that are intended to reduce the absorption of a poison or enhance its elimination are now only rarely indicated. Antidotes (e.g., atropine, 4-dimethylaminophenol, naloxone, toluidine blue) are available for only a few kinds of poisoning. Randomized clinical trials of treatment have been carried out for only a few substances. Most exposures to poisons can be treated with general emergency care and, if necessary, with symptomatic intensive-care measures. Poison information centers help ensure that cases of poisoning are dealt with efficiently. The data they collect are a useful aid to toxicological assessment and can serve as a point of departure for research projects.

    Organophosphates (OPs) pesticides are among the most toxic synthetic chemicals purposefully added in the environment. The common use of OP insecticides in public health and agriculture results in an environmental pollution and a number of acute and chronic poisoning events. Present study was aimed to evaluate the potential of monocrotophos and quinalphos to effect the redox status and glutathione (GSH) homeostasis in rat tissues and find out whether antioxidant vitamins have some protection on the pesticide-induced alterations. The results showed that these pesticides alone or in combination, caused decrease in the levels of GSH and the corresponding increase in the levels of GSSG, decreasing the GSH/GSSG ratio. The results also showed that NADPH/NADP(+) and NADH/NAD(+) ratios were decreased in the liver and brain of rats on exposure with mococrotophos, quinalphos, and their mixture. These pesticides, alone or in combination, caused alterations in the activities of GSH reductase and glucose-6-phosphate dehydrogenase in the rat tissues. However, the expression of the GSH recycling enzymes did not show significant alterations as compared to control. From the results, it can be concluded that these pesticides generate oxidative stress but their effects were not synergistic when given together and prior feeding of antioxidant vitamins tend to reduce the toxicities of these pesticides.

    Ciguatera poisoning appears after ingestion of contaminated fish from tropical coral reefs. Due to the diversity of clinical symptoms and the absence of a specific test in humans, the diagnosis is often difficult. A retrospective study of 10 patients consulting for a clinical and epidemiological picture compatible with ciguatera poisoning after a trip to tropical countries between 1993 and 2000. Most infections but one were acquired in the Caribbean area and there were 8 females. Clinical manifestations started within the first 24 hours after fish ingestion. Chief symptoms were diarrhea and nausea, followed by neurological symptoms, mainly limbs paresthesias that persisted for several weeks. The severity of clinical symptoms was variable and not related to age or initial symptoms. Ciguatera poisoning has to be considered in the diagnosis of acute gastroenteritis affecting travellers to tropical areas.

    Autopsy findings of game that died presumably due to poisoning by arsenic are presented. Corrosive gastroenteritis with edema and ecchymosis of the mucosa, and partly ulceration of the stomach, and fatty degeneration of the kidneys and liver were found in hares and stags. Arsenic was detected in the gastric content, liver, and other organs. These cases were diagnosed as acute to subacute poisoning by arsenic. Catarrhal gastrointestinal mucosa, pseudomembranes, in the esophagus, inflammatory edema of the nasal septum and laryngeai mucosa, and sometimes liver cirrhosis and edema of the spleen were found in red deer, roes, and hares. In these cases, poisoning by arsenic could not be identified as the primary cause of death. The symptoms of the poisoning were similar to cause of death. The symptoms of the poisoning were similar to those observed in game around a smelter prior to the installation of an efficient arsenic trap.

    Wild mushroom poisoning is often reported to cause acute liver or renal failure. However, acute rhabdomyolysis caused by wild mushroom poisoning has rarely been reported. We describe 7 patients of 1 family with Russula subnigricans Hongo poisoning. Their clinical manifestations varied from gastrointestinal symptoms to rhabdomyolysis, with 1 fatality. Our report provides supporting evidence that rhabdomyolysis may result from ingestion of R subnigricans mushrooms. A key to survival for patients with rhabdomyolysis caused by R subnigricans poisoning may be early recognition and intensive supportive care. Copyright © 2015 Wilderness Medical Society.

    Full Text Available Poison hemlock (Conium maculatum is a plant that is poisonous for humans and animals. Accidental ingestion of the plant may result in central nervous system depression, respiratory failure, acute rhabdomyolysis, acute renal failure and even death. The main treatment of hemlock poisoning is supportive care. The case of a 6-year-old girl who was admitted to the emergency department with complaints of burning sensation in mouth, hypersalivation, tremor in hands and ataxia after ingestion of poison hemlock is presented here with clinical and laboratory features. In this case, we aim to report that accidental ingestion of plants resembling vegetables that are consumed daily can lead to serious complications and even death.

    The study aims to provide a comprehensive trend of pesticide poisoning cases in the Philippines as well as pesticide exposures, and risk factors related to the adverse effects of pesticide. Records were gathered from the National Poison Control and Management Center (NPCMC), the Philippine General Hospital, De La Salle Medical Center, and other hospitals, and reviewed research studies conducted in the Philippines. Based on hospital surveys, the number of pesticide cases as well as mortality trends have been increasing. Studies from 2006 to 2010 showed that human health especially those of the farmers is at risk due to pesticide exposure. Illnesses and symptoms such as headache, skin abnormalities, fatigue, fever, and weaknesses were the common health complaints experienced by the farmers as reported in the research studies. Moreover, the studies showed risk factors to pesticide exposure, work practices, and pesticide residues in environmental media that could be contributory to pesticide poisoning cases. Government agencies should intensify their surveillance and regulation on both household and agricultural pesticides. The state of pesticide-related illnesses mirrors the poor safety practices among farmers as well as lack of necessary supervision from the government agencies.

    This is a case report concerning a veterinarian who spilled detomidine and butorphanol on dermatitic hands while sedating a horse. This resulted in acute poisoning from which the patient spontaneously recovered with supportive management. Veterinarians often suffer from occupational dermatitis and handle strong sedatives with no gloves while working around unpredictable animals. Thus, this group is at risk of accidental self-poisoning from this method.

    2007-01-01

    The availability of highly toxic organophosphorus (OP) warfare agents (nerve agents) underlines the necessity for an effective medical treatment. Acute OP toxicity is primarily caused by inhibition of acetylcholinesterase (AChE). Reactivators (oximes) of inhibited AChE are a mainstay of treatment, however, the commercially available compounds, obidoxime and pralidoxime, are considered to be rather ineffective against various nerve agents, e.g. soman and cyclosarin. This led to the synthesis and investigation of numerous oximes in the past decades. Reactivation of OP-inhibited AChE is considered to be the most important reaction of oximes. Clinical data from studies with pesticide-poisoned patients support the assumption that the various reactions between AChE, OP and oxime, i.e. inhibition, reactivation and aging, can be investigated in vitro with human AChE. In contrast to animal experiments such in vitro studies with human tissue enable the evaluation of oxime efficacy without being affected by species differences. In the past few years numerous in vitro studies were performed by different groups with a large number of oximes and methods were developed for extrapolating in vitro data to different scenarios of human nerve agent poisoning. The present status in the evaluation of new oximes as antidotes against nerve agent poisoning will be discussed

    Full Text Available The available antidotal therapy against acute poisoning by organophosphates involves the use of atropine alone or in combination with one of the oximes, e.g. 2-PAM, Obidoxime, TMB-4 or HI-6. Each of these oximes has some limitation, raising the question of the universal antidotal efficacy against poisoning by all OPs/nerve agents. In the present study, newly synthesized bis quaternary 2-(hydroxyimino-N-(pyridin-3yl acetamide derivatives (HNK-series oximes were evaluated for their antidotal efficacy against DDVP intoxicated Swiss mice, in terms of the Protection Index (PI and AChE reactivation in brain and serum. The inhibition concentration (IC50 was determined in brain and serum after optimizing the time point for maximum inhibition (60 min post DDVP exposure. AChE reactivation efficacy of the HNK series was evaluated at IC50 and compared with 2-PAM. HNK-102 showed a ~2 times better Protection Index (PI as compared to 2-PAM against DDVP toxicity. IC50 at 60 min DDVP post exposure was found to be approximately one fifth and one half of the LD50 dose for brain and serum AChE, respectively. Out of three HNK oximes, HNK-102 & 106 at 0.20 LD50 dose significantly reactivated DDVP intoxicated brain AChE (p<0.05 as compared to 2-PAM at double IC50 dose of DDVP. In light of double PI and higher AChE reactivation, HNK 102 was found to be a better oxime than 2-PAM in the treatment of acute poisoning by DDVP.

  13. Pesticide acute toxicity is a better correlate of U.S. grassland bird declines than agricultural intensification.

    Directory of Open Access Journals (Sweden)

    Pierre Mineau

    Full Text Available Common agricultural birds are in decline, both in Europe and in North America. Evidence from Europe suggests that agricultural intensification and, for some species, the indirect effects of pesticides mediated through a loss of insect food resource is in part responsible. On a state-by-state basis for the conterminous Unites States (U.S., we looked at several agronomic variables to predict the number of grassland species increasing or declining according to breeding bird surveys conducted between 1980 and 2003. Best predictors of species declines were the lethal risk from insecticide use modeled from pesticide impact studies, followed by the loss of cropped pasture. Loss of permanent pasture or simple measures of agricultural intensification such as the proportion of land under crop or the proportion of farmland treated with herbicides did not explain bird declines as well. Because the proportion of farmland treated with insecticides, and more particularly the lethal risk to birds from the use of current insecticides feature so prominently in the best models, this suggests that, in the U.S. at least, pesticide toxicity to birds should be considered as an important factor in grassland bird declines.

    Arsenic (As) is commonly known as a poison. Only a few people know that As has also been widely used in medicine. In the past years As and its compounds were used as a medicine for the treatment of such diseases as diabetes, psoriasis, syphilis, skin ulcers and joint diseases. Nowadays As is also used especially in the treatment of patients with acute promyelocytic leukemia. The International Agency for Research on Cancer (IARC) has recognized arsenic as an element with carcinogenic effect evidenced by epidemiological studies, but as previously mentioned it is also used in the treatment of neoplastic diseases. This underlines the specificity of the arsenic effects. Arsenic occurs widely in the natural environment, for example, it is present in soil and water, which contributes to its migration to food products. Long exposure to this element may lead to liver damages and also to changes in myocardium. Bearing in mind that such serious health problems can occur, monitoring of the As presence in the environmental media plays a very important role. In addition, the occupational risk of As exposure in the workplace should be identified and checked. Also the standards for As presence in food should be established. This paper presents a review of the 2015 publications based on the Medical database like PubMed and Polish Medical Bibliography. It includes the most important information about arsenic in both forms, poison and medicine. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

    A wide range of plants contain nicotinic and nicotinic-like alkaloids. Of this diverse group, those that have been reported to cause human poisoning appear to have similar mechanisms of toxicity and presenting patients therefore have comparable toxidromes. This review describes the taxonomy and principal alkaloids of plants that contain nicotinic and nicotinic-like alkaloids, with particular focus on those that are toxic to humans. The toxicokinetics and mechanisms of toxicity of these alkaloids are reviewed and the clinical features and management of poisoning due to these plants are described. This review was compiled by systematically searching OVID MEDLINE and ISI Web of Science. This identified 9,456 papers, excluding duplicates, all of which were screened. Reviewed plants and their principal alkaloids. Plants containing nicotine and nicotine-like alkaloids that have been reported to be poisonous to humans include Conium maculatum, Nicotiana glauca and Nicotiana tabacum, Laburnum anagyroides, and Caulophyllum thalictroides. They contain the toxic alkaloids nicotine, anabasine, cytisine, n-methylcytisine, coniine, n-methylconiine, and gamma-coniceine. These alkaloids act agonistically at nicotinic-type acetylcholine (cholinergic) receptors (nAChRs). The nicotinic-type acetylcholine receptor can vary both in its subunit composition and in its distribution within the body (the central and autonomic nervous systems, the neuromuscular junctions, and the adrenal medulla). Agonistic interaction at these variable sites may explain why the alkaloids have diverse effects depending on the administered dose and duration of exposure. Nicotine and nicotine-like alkaloids are absorbed readily across all routes of exposure and are rapidly and widely distributed, readily traversing the blood-brain barrier and the placenta, and are freely distributed in breast milk. Metabolism occurs predominantly in the liver followed by rapid renal elimination. Following acute exposure

    The purpose of this study is to evaluate the association between pesticides and neurological symptoms among a population exposed to organophosphate chemicals as a result of agricultural use. Chronic squealed of acute pesticide poisoning from organophosphate compounds include a variety of neurological symptoms including restlessness, irritability, and trouble sleeping. Individuals who have had an acute pesticide poisoning have been reported to suffer a wide range of neurological symptoms that occur from weeks to months after the initial episode. Data for this study came from a cross-sectional survey of farmers and their spouses conducted in an eight-county area in northeastern Colorado. Neurological characteristics were assessed to determine their relationship with previously reported pesticide-related illnesses. Symptoms that were significantly associated with previous poisoning were difficulty concentrating [OR 2.07, 95% confidence interval (CI) 1.22, 3.50]; relatives noticing person had trouble remembering things (OR 2.54, 95% CI 1.47, 4.39); making notes to remember things (OR .18, 95% CI 1.20, 3.97); finding it hard to understand the meaning of newspapers, magazines, and books (OR 1.90, 95% CI 1.01, 3.60); felt irritable OR 1.84, 95% CI 1.08, 3.12); felt depressed (OR 2.82, 95% CI 1.65, 4.81); ad heart palpitations without exertion (OR 2.83, 95% CI 1.22, 6.54); sleeping more than usual (OR 3.58, 95% CI 1.95, 6.58); difficulty moving fingers or grasping things (OR 2.08, 95% CI 1.06, 3.24); and headaches at least once a week (OR 1.85, 95% CI 1.06, 3.24). Stepwise regression was used o identify the best explanatory model of pesticide-related illness. Variables that were associated with increased odds of illness were being ale, being depressed, sleeping too much, and using crop organophosphates

    The purpose of this study was to determine the extent to which poison center triage guidelines influence healthcare facility referral rates for acute, unintentional acetaminophen-only poisoning and acute, unintentional adult formulation iron poisoning. Managers of US poison centers were interviewed by telephone to determine their center's triage threshold value (mg/kg) for acute iron and acute acetaminophen poisoning in 1997. Triage threshold values and healthcare facility referral rates were fit to a univariate logistic regression model for acetaminophen and iron using maximum likelihood estimation. Triage threshold values ranged from 120-201 mg/kg (acetaminophen) and 16-61 mg/kg (iron). Referral rates ranged from 3.1% to 24% (acetaminophen) and 3.7% to 46.7% (iron). There was a statistically significant inverse relationship between the triage value and the referral rate for acetaminophen (p variability in poison center triage values and referral rates for iron and acetaminophen poisoning. Guidelines can account for a meaningful proportion of referral variation. Their influence appears to be substance dependent. These data suggest that efforts to determine and utilize the highest, safe, triage threshold value could substantially decrease healthcare costs for poisonings as long as patient medical outcomes are not compromised.

    Full Text Available Abstract Background In Great Britain (GB, data collected on pesticide associated illness focuses on acute episodes such as poisonings caused by misuse or abuse. This study aimed to investigate the extent and nature of pesticide-related illness presented and diagnosed in Primary Care and the feasibility of establishing a routine monitoring system. Methods A checklist, completed by General Practitioners (GP for all patients aged 18+ who attended surgery sessions, identified patients to be interviewed in detail on exposures and events that occurred in the week before their symptoms appeared. Results The study covered 59320 patients in 43 practices across GB and 1335 detailed interviews. The annual incidence of illness reported to GPs because of concern about pesticide exposure was estimated to be 0.04%, potentially 88400 consultations annually, approximately 1700 per week. The annual incidence of consultations where symptoms were diagnosed by GPs as likely to be related to pesticide exposure was 0.003%, an annual estimate of 6630 consultations i.e. about 128 per week. 41% of interviewees reported using at least one pesticide at home in the week before symptoms occurred. The risk of having symptoms possibly related to pesticide exposure compared to unlikely was associated with home use of pesticides after adjusting for age, gender and occupational pesticide exposure (OR = 1.88, 95% CI 1.51 – 2.35. Conclusion GP practices were diverse and well distributed throughout GB with similar symptom consulting patterns as in the Primary Care within the UK. Methods used in this study would not be feasible for a routine surveillance system for pesticide related illness. Incorporation of environmental health into Primary Care education and practice is needed.

    Purpose: To decrease the effect of water elimination and the effect of burn-up residue boron, thereby reduce the effect of burnable poison rods as the neutron poisons at the final stage of reactor core lifetime. Constitution: In a burnable poison rod according to the present invention, a hollow burnable poison material is filled in an external fuel can, an inner fuel can mounted with a carbon rod is inserted to the hollow portion of the burnable poison material and helium gases are charged in the outer fuel can. In such a burnable poison rod, the reactivity worths after the burning are reduced to one-half as compared with the conventional case. Accordingly, since the effect of the burnable poison as the neutron poisons is reduced at the final stage of the reactor core of lifetime, the excess reactivity of the reactor core is increased.

    The effect of joint external γ-radiation and some pesticides on the peripheric blood is studied. Lindane, trichlorfon and tetramethylthiuram disulfide are used as toxic chemicals. It is shown that the combined effect has caused, like radiation, stable leukopenia, but less expressed than the effect of gamma radiation. It is especially obvious in the case of combining ionizing radiation and TMTD when the number of leukocytes averaged by 25% more than in the case of injury by radiation alone. Lymphocytes are most sensitive blood cell elements earily responsing to radiation and chemical organism injuries, both qualitatively and quantitatively. The results of analyzing the dynamics of the most qualitative and quantitative paramaters of leukocytes permit to state the summation of mutual effects of factors of radiation and chemical nature

    Accidental self-poisoning or deliberate use in suicidal intent of organophosphorus pesticides (OPP), which are widely used in agriculture, represent a health problem worldwide. Symptoms of poisoning are characterized by acute cholinergic crisis caused by inhibition of acetylcholinesterase. A 75-year-old male patient ingested 20ml of an OPP solution containing 10% methamidophos in suicidal intent. In the course of poisoning typical clinical symptoms of cholinergic crisis (miosis, bradycardia, hypotension, hypersalivation and impairment of neurologic status) were evident. Butyryl (plasma) cholinesterase (BChE) and red blood cell acetylcholinesterase (RBC-AChE) revealed decreased activities, thus specific treatment with the enzyme reactivator obidoxime was started. Inhibitory activity of the patient's plasma indicated significant amounts of persisting methamidophos in the circulation and was still found on day 4 after ingestion. Due to missing spontaneous breathing on day 6, obidoxime was administered again. Afterwards a significant increase of RBC-AChE activity was found. The patient was extubated on day 10 and a restitution ad integrum was achieved. In conclusion, obidoxime is a potent reactivator of OPP-inhibited AChE. A repetitive and prolonged administration of obidoxime should be considered in cases of severe methamidophos poisoning and should be tailored with an advanced analytical biomonitoring.

    , tremors, hypothermia, and bradycardia. Higher dosages may additionally cause nystagmus, agitation, tachypnea, tachycardia, ataxia, hyperexcitability, and seizures. Treatment of marijuana ingestion in animals is largely supportive. Vital signs including temperature and heart rate and rhythm must be continually monitored. Stomach content and urine can be tested for cannabinoids. Gas chromatography and mass spectrometry can be utilized for THC detection but usually may take several days and are not practical for initiation of therapy. Human urine drug-screening tests can be unreliable for confirmation of marijuana toxicosis in dogs owing to the interference of a large number of the metabolites in canine urine. False negatives may also arise if testing occurs too recently following THC ingestion. Thus, the use of human urine drug-screening tests in dogs remains controversial. No specific antidote presently exists for THC poisoning. Sedation with benzodiazepines may be necessary if dogs are severely agitated. Intravenous fluids may be employed to counter prolonged vomiting and to help control body temperature. Recently, the use of intralipid therapy to bind the highly lipophilic THC has been utilized to help reduce clinical signs. The majority of dogs experiencing intoxication after marijuana ingestion recover completely without sequellae. Differential diagnoses of canine THC toxicosis include human pharmaceuticals with central nervous system stimulatory effects, drugs with central nervous system depressant effects, macrolide parasiticides, xylitol, and hallucinogenic mushrooms.

    Neonicotinoids are novel systemic pesticides acting as agonists on the nicotinic acetylcholine receptors (nAChRs) of insects. Experimental studies have revealed that neonicotinoids pose potential risks for the nervous systems of non-target species, but the brain regions responsible for their behavioral effects remain incompletely understood. This study aimed to assess the neurobehavioral effects of clothianidin (CTD), a later neonicotinoid developed in 2001 and widely used worldwide, and to explore the target regions of neonicotinoids in the mammalian brain. A single-administration of 5 or 50mg/kg CTD to male C57BL/6N mice at or below the no-observed-adverse-effect level (NOAEL) induced an acute increase in anxiety during the elevated plus-maze test. In addition, mice in the CTD-administered group spontaneously emitted human-audible vocalizations (4-16kHz), which are behavioral signs of aversive emotions, and showed increased numbers of c-fos immunoreactive cells in the paraventricular thalamic nucleus and dentate gyrus of the hippocampus. In conclusion, mice exposed to NOAEL-dose CTD would be rendered vulnerable to a novel environment via the activation of thalamic and hippocampal regions related to stress responses. These findings should provide critical insight into the neurobehavioral effects of neonicotinoids on mammals. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Este trabalho é parte de um estudo mais amplo sobre as conseqüências para a saúde da exposição a pesticidas. Em 1997, no Município de Paty do Alferes, Rio de Janeiro, 55 agricultores foram entrevistados sobre o uso de pesticidas, equipamentos de proteção e medidas de higiene, ocorrência de intoxicações, destino das embalagens vazias e o tipo de orientação técnica recebida pelos usuários destes produtos. Os pesticidas mais usados foram inseticidas como a abamectina, os compostos organofosforados e os piretróides, e os fungicidas como o mancozeb, o clorotalonil e produtos à base de cobre. Entre os trabalhadores envolvidos no preparo e/ou aplicação de pesticidas, 92% informaram não usar qualquer tipo de equipamento de proteção individual. 62% dos agricultores entrevistados informaram já ter "passado mal" ao preparar ou aplicar pesticidas. Os sintomas mais freqüentemente citados foram dor de cabeça, enjôo, vômitos, vertigem, irritação da pele e visão embaçada. Destes agricultores, 21% necessitaram de assistência médica e em mais da metade dos casos (51%, em que os lavradores identificaram os pesticidas que usavam quando "passaram mal", foram citados inseticidas organofosforados da classe toxicológica I.This survey is part of a more comprehensive study on the health consequences of pesticide exposure.
