Assessment of quality indicators allows clinicians to evaluate clinical assistance with a standard, to detect deficiencies and to improve medical assistance. Patients who came to emergency services of a tertiary level hospital for suspicion of poisoning from January 2011 to June 2012 were assessed using 20 quality indicators of pediatric poisoning. Data collection was performed by retrospective review of clinical reports. A total of 393 patients were admitted for suspicion of poisoning (0.3% of all admissions).The standard was reached in 11 indicators and not reached in 6: administration of activated charcoal within 2hours of poison ingestion (standard=90%, result=83.5%); attention within the first 15minutes of arriving in the emergency service (standard=90%, result=60.4%); start of gastrointestinal decontamination within 20minutes of arrival in emergency services (standard=90%, result=29.7%); performing of electrocardiogram on the patients poisoned with cardiotoxic substances (standard=95%, result=87%); judicial communication of cases of poisoning that could conceal a crime (standard=95%, result=31.3%), and collection of the minimal set of information of poisoned patients (standard=90%, result=1.9%). Three indicators could not be evaluated as a consequence of the limited number of cases where they could be applied (de Pediatría. Published by Elsevier Espana. All rights reserved.

To determine the epidemiological profile and risk factors of voluntary poisoning by pesticides. 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. 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%. 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.

Digoxin poisoning still remains a common cause of morbidity and mortality. Fortunately, digoxin-specific Fab fragments are commercially available as an antidote. However, these Fab fragments are several thousand dollars per vial. There is a standardized formula to calculate appropriate Fab fragment dosage based on the serum digoxin concentration. This can greatly reduce the amount of Fab fragment administered. There is also an empiric dosing guideline recommending 6-10 vials be given; however, this may result in higher amounts of Fab fragments being administered than required. We performed this study to assess the amounts of digoxin-specific Fab fragments administered in the treatment of digoxin poisonings recorded in a poison control system database from January 1, 2000, to December 31, 2009, in which digoxin serum concentrations were available. This was a retrospective study of 278 patients, 107 with acute poisonings (group A) and 171 following chronic poisoning (group B). In group A, the calculated Fab dose was higher than the calculated dose based on available concentrations in 39 (36%) of group A and 15 (9%) of group B patients. The average wholesale price cost of the excessive dosages ranged from $4818 to as high as $50,589 per patient. Our data suggests that clinician education on digoxin poisoning and the use of the standardized formula to calculate the Fab dose may decrease over utilization and decrease costs associated with the administration of digoxin-specific Fab fragments in the treatment of digoxin poisonings.

Full Text Available Abstract Background The national incidence of and risk factors for hospitalized poisonings in renal transplant recipients has not been reported. Methods Historical cohort study of 39,628 renal transplant recipients in the United States Renal Data System between 1 July 1994 and 30 June 1998. Associations with time to hospitalizations for a primary diagnosis of poisonings (ICD-9 codes 960.x-989.x within three years after renal transplant were assessed by Cox Regression. Results The incidence of hospitalized poisonings was 2.3 patients per 1000 person years. The most frequent causes of poisonings were immunosuppressive agents (25.3%, analgesics/antipyretics (14.1%, psychotropic agents (10.0%, and insulin/antidiabetic agents (7.1%. In Cox Regression analysis, low body mass index (BMI, 28.3 kg/m2, adjusted hazard ratio (AHR, 3.02, 95% CI, 1.45–6.28, and allograft rejection, AHR 1.83, 95% CI, 1.15–2.89, were the only factors independently associated with hospitalized poisonings. Hospitalized poisonings were independently associated with increased mortality (AHR, 1.54, 95% CI 1.22–1.92, p = 0.002. Conclusions Hospitalized poisonings were associated with increased mortality after renal transplantation. However, almost all reported poisonings in renal transplant recipients were due to the use of prescribed medications. Allograft rejection and low BMI were the only independent risk factors for poisonings identified in this population.

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 Carbon monoxide (CO poisoning may cause toxicity to the cardiovascular system. However, the association between CO poisoning and the risk of major adverse cardiovascular events (MACE remains unestablished. We investigated the incidence of MACE after CO poisoning in Taiwan and evaluated whether CO-poisoned individuals had a higher risk of MACE than did the general population.Using Taiwan's National Health Insurance Research Database (NHIRD during 2005-2013, a nationwide population-based cohort study was conducted among patients who experienced CO poisoning between 2005 and 2013. CO poisoning was defined according to the International Classification of Diseases, Ninth Revision, Clinical Modification codes. The study cohort comprised patients with CO poisoning between 2005 and 2010 (N = 13,939. Each patient was matched according to age, sex and index date with four randomly selected controls from the comparison cohort (N = 55,756. All patients were followed from the study date until MACE development, death, or the end of 2013. The hazard ratios for MACE were compared between the two cohorts by using Cox proportional hazards regressions analyses.Incident cases of MACE were identified from the NHIRD. After adjustment for potential confounders, the study cohort was independently associated with a higher MACE risk (adjusted hazard ratio, 2.00; 95% confidence interval, 1.83-2.18.This population-based cohort study indicated that patients with CO poisoning have a higher risk of MACE than do individuals without CO poisoning.

AIMS: To identify risk factors in the development of side-effects to N-acetylcysteine (NAC) in patients with paracetamol poisoning. METHODS: A retrospective study was carried out based upon the hospital charts of 529 consecutive patients admitted with paracetamol poisoning, all treated with NAC...... 2.9 times (95% CI 2.1, 4.7) more likely to develop side-effects (Chi-square: P = 0.004). Side-effects were of similar severity in asthmatics and nonasthmatics. A history of medical allergy was not a risk factor. Serum paracetamol was lower in patients with side-effects than in those without (Mann......-Whitney: P = 0.00006). CONCLUSIONS: Asthma must be considered a risk factor in the development of side-effects to NAC. However, the side-effects are easily managed and there is no reason to withhold NAC from any patient with paracetamol poisoning. Paracetamol itself seems to offer some protection against...

Intentional self-poisoning that is widely used all over the world is one of the most common methods of suicide. This study aim was to determine the rate of attempted intentional self-poisoning and to identify high risk persons in the west of Iran (Kermanshah). A total of 3138 people (1279 M and 1859 F) studied. The average annual rate of suicide in Kermanshah was 153 persons per 100 000 people. The most number of attempted intentional self-poisoning (55.5%) were in the 20-29 year age group. The most popular toxic substances for self-poisoning were drugs (71%) and oil and fuels (15%), respectively. The most number of intentional self-poisoning suicides are attempted by drugs. By considering the high rate of intentional self-poisoning, low age of suicide attempts and also its high mortality rate in Kermanshah, it is necessary to stop the opportunity to buy over-the-counter (OTC) drugs, especially those being most misused.

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.

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.

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.

The aim of this study is to assess the nature and quality of services provided by poison information center established at a tertiary-care teaching hospital, Mysore. This was a prospective observational study. The poison information center was officially established in September 2010 and began its functioning thereafter. The center is equipped with required resources and facility (e.g., text books, Poisindex, Drugdex, toll free telephone service, internet and online services) to provide poison information services. The poison information services provided by the center were recorded in documentation forms. The documentation form consists of numerous sections to collect information on: (a) Type of population (children, adult, elderly or pregnant) (b) poisoning agents (c) route of exposure (d) type of poisoning (intentional, accidental or environmental) (e) demographic details of patient (age, gender and bodyweight) (f) enquirer details (background, place of call and mode of request) (g) category and purpose of query and (h) details of provided service (information provided, mode of provision, time taken to provide information and references consulted). The nature and quality of poison information services provided was assessed using a quality assessment checklist developed in accordance with DSE/World Health Organization guidelines. Chi-Square test (χ(2)). A total of 419 queries were received by the center. A majority (n = 333; 79.5%) of the queries were asked by the doctors to provide optimal care (n = 400; 95.5%). Most of the queries were received during ward rounds (n = 201; 48.0%), followed by direct access (n = 147; 35.1%). The poison information services were predominantly provided through verbal communication (n = 352; 84.0%). Upon receipt of queries, the required service was provided immediately (n = 103; 24.6%) or within 10-20 min (n = 296; 70.6%). The queries were mainly related to intentional poisoning (n = 258; 64.5%), followed by accidental poisoning

Priority setting for risk assessment-The benefit of human experience

International Nuclear Information System (INIS)

Alonzo, Cristina; Laborde, Amalia

2005-01-01

The chemical risk assessment process plays an essential role in the potential human health risk evaluation. Setting priorities for this purpose is critical for better use of the available human and material resources. It has been generally accepted that all new chemicals require safety evaluation before manufacture and sale. This is a difficult task due to the large number of chemicals directly consumed by man, as well as those that are widely used. At present, more than 50% of chemicals do not have the minimum data requirements for risk assessment. Production and release volumes are well-established prioritization criteria, although volume itself does not directly reflect the likelihood of human exposure. This quantitative approach applied in setting priorities may be influenced by human experience. Human data provided by epidemiological investigations have been accepted as the most credible evidence for human toxicity although analytical studies are expensive and require long-term follow up. Unfortunately, some epidemiological studies continue to have difficulties with exposure documentation, controlling bias and confounding, and are not able to provide predictions of risk until humans are exposed. Clinical toxicology services and Poison Centres around the world accumulate a great amount of toxicological-related information that may contribute to the evidence-based medicine and research and so collaborate with all the risk assessment disciplines. The information obtained from these services and centers has the potential to prioritize existing chemical assessment processes or to influence scheduling of classes of chemicals. Prioritization process may be improved by evaluating Poisons Centres statistics about frequency of cases, severity of effects, detection of unusual circumstances of exposure, as well as vulnerable sub-populations. International efforts for the harmonization of these data offer a useful tool to take advantage of this global information. Case

Long-term consequences of arsenic poisoning during infancy due to contaminated milk powder

Directory of Open Access Journals (Sweden)

Grandjean Philippe

2006-10-01

Full Text Available Abstract Arsenic toxicity is a global health problem affecting many millions of people. The main source of exposure is drinking water contaminated by natural geological sources. Current risk assessment is based on the recognized carcinogenicity of arsenic, but neurotoxic risks have been overlooked. In 1955, an outbreak of arsenic poisoning occurred among Japanese infants, with more than 100 deaths. The source was contaminated milk powder produced by the Morinaga company. Detailed accounts of the Morinaga dried milk poisoning were published in Japanese only, and an overview of this poisoning incident and its long-term consequences is therefore presented. From analyses available, the arsenic concentration in milk made from the Morinaga milk powder is calculated to be about 4–7 mg/L, corresponding to daily doses slightly above 500 μg/kg body weight. Lower exposures would result from using diluted milk. Clinical poisoning cases occurred after a few weeks of exposure, with a total dose of about 60 mg. This experience provides clear-cut evidence for hazard assessment of the developmental neurotoxicity. At the present time, more than 600 surviving victims, now in their 50s, have been reported to suffer from severe sequelae, such as mental retardation, neurological diseases, and other disabilities. Along with more recent epidemiological studies of children with environmental arsenic exposures, the data amply demonstrate the need to consider neurotoxicity as a key concern in risk assessment of inorganic arsenic exposure.

Lithium Poisoning

DEFF Research Database (Denmark)

Baird-Gunning, Jonathan; Lea-Henry, Tom; Hoegberg, Lotte C G

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...

Risk Assessment of Shellfish Toxins

Directory of Open Access Journals (Sweden)

Rex Munday

2013-11-01

Full Text Available Complex secondary metabolites, some of which are highly toxic to mammals, are produced by many marine organisms. Some of these organisms are important food sources for marine animals and, when ingested, the toxins that they produce may be absorbed and stored in the tissues of the predators, which then become toxic to animals higher up the food chain. This is a particular problem with shellfish, and many cases of poisoning are reported in shellfish consumers each year. At present, there is no practicable means of preventing uptake of the toxins by shellfish or of removing them after harvesting. Assessment of the risk posed by such toxins is therefore required in order to determine levels that are unlikely to cause adverse effects in humans and to permit the establishment of regulatory limits in shellfish for human consumption. In the present review, the basic principles of risk assessment are described, and the progress made toward robust risk assessment of seafood toxins is discussed. While good progress has been made, it is clear that further toxicological studies are required before this goal is fully achieved.

The relationship between arsenic exposure and DNA damage in patients with acute or chronic arsenic poisoning was analyzed. Urinary 8-hydroxydeoxyguanine (8-OHdG) concentrations were measured as an indication of oxidative DNA damage. A remarkable increase in 8-OHdG in the urine was observed in 60% of 52 patients with acute arsenic poisoning from the accidental oral intake of the arsenic trioxide. This was two- to threefold higher than levels in normal healthy subjects (n = 248). There was a clear relationship between arsenic concentrations in urine after acute poisoning and elevated levels of 8-OHdG. Levels of urinary 8-OHdG returned to normal within 180 days after the acute arsenic poisoning event. In patients chronically poisoned by the consumption of well water with elevated levels of arsenate [As(V)], elevated 8-OHdG concentrations in urine were also observed. A significant correlation between the 8-OHdG levels and arsenic levels in the urine was observed in 82 patients with chronic poisoning. Thus, evidence of oxidative DNA damage occurred in acute arsenic poisoning by arsenite [As(III)] and in chronic arsenic poisoning by As(V). In chronic poisoning patients provided low-arsenic drinking water, evidence of DNA damage subsided between 9 months and 1 year after the high levels of arsenic intake were reduced. The initial level of arsenic exposure appeared to dictate the length of this recovery period. These data indicate that some aspects of chronic and acute arsenic poisoning may be reversible with the cessation of exposure. This knowledge may contribute to our understanding of the risk elevation from arsenic carcinogenesis and perhaps be used in a prospective fashion to assess individual risk

The Toxic Exposure Surveillance System (TESS) is a uniform data set of US poison centers cases. Categories of information include the patient, the caller, the exposure, the substance(s), clinical toxicity, treatment, and medical outcome. The TESS database was initiated in 1985, and provides a baseline of more than 36.2 million cases through 2003. The database has been utilized for a number of safety evaluations. Consideration of the strengths and limitations of TESS data must be incorporated into data interpretation. Real-time toxicovigilance was initiated in 2003 with continuous uploading of new cases from all poison centers to a central database. Real-time toxicovigilance utilizing general and specific approaches is systematically run against TESS, further increasing the potential utility of poison center experiences as a means of early identification of potential public health threats

Toxicovigilance: A new approach for the hazard identification and risk assessment of toxicants in human beings

International Nuclear Information System (INIS)

Descotes, Jacques; Testud, Francois

2005-01-01

The concept of toxicovigilance encompasses the active detection, validation and follow-up of clinical adverse events related to toxic exposures in human beings. Poison centers are key players in this function as poisoning statistics are essential to define the cause, incidence and severity of poisonings occurring in the general population. In addition, the systematic search for unexpected shifts in the recorded causes of poisonings, e.g., following the introduction of a new product, or change in the formulation or recommended use of an old product, allows for a rapid detection of potential adverse health consequences and the implementation of preventive or corrective measures. However, toxicovigilance is genuinely a medical and not only a statistical approach of human toxicity issues. In contrast to epidemiology, toxicovigilance is based on the in-depth medical assessment of acute or chronic intoxications on an individual basis, which requires detailed information that poison centers can rarely obtain via emergency telephone calls and that epidemiologists cannot collect or process. Validation of this medical information must primarily be based on toxicological expertise to help identify causal links between otherwise unexplained pathological conditions and documented toxic exposures. Thus, toxicovigilance can contribute to hazard identification and risk assessment by providing medically validated data which are often overlooked in the process of risk assessment. So far, very few structured toxicovigilance systems have been set up and hopefully national and international initiatives will bridge this gap in our knowledge of the toxicity of many chemicals and commercial products in human beings

Storm-Related Carbon Monoxide Poisoning: An Investigation of Target Audience Knowledge and Risk Behaviors.

Damon, Scott A; Poehlman, Jon A; Rupert, Douglas J; Williams, Peyton N

Carbon monoxide (CO) poisonings in the United States consistently occur when residents improperly use portable gasoline-powered generators and other tools following severe storms and power outages. However, protective behaviors-such as installing CO alarms and placing generators more than 20 feet away from indoor structures-can prevent these poisonings. This study identified knowledge, attitudes, and beliefs that lead consumers to adopt risk and protective behaviors for storm-related CO poisoning and post-storm generator use. Four focus groups (32 participants in total) were conducted with generator owners in winter and summer storm-prone areas to explore home safety, portable generator use, CO poisoning knowledge, and generator safety messages. Discussions were transcribed, and findings analyzed using an ordered meta-matrix approach. Although most generator owners were aware of CO poisoning, many were unsure what constitutes a safe location for generator operation and incorrectly stated that enclosed areas outside the home-such as attached garages, sheds, and covered porches-were safe. Convenience and access to appliances often dictated generator placement. Participants were receptive to installing CO alarms in their homes but were unsure where to place them. These findings suggest a deficit in understanding how to operate portable generators safely and a need to correct misconceptions around safe placement. In terms of behavioral price, the simple installation and maintenance of inexpensive CO alarms may be the most important strategy for ultimately protecting homes from both storm-related and other CO exposures.

Conclusion: Children with CO poisoning had good outcomes in this series. Although improperly vented exhaust from water heaters and house fires were the most common causes, intentional poisoning by parents through charcoal burning was also an important factor. Early identification of DNS risk factors might help to provide better care.

An Outbreak of Foxglove Leaf Poisoning

Full Text Available Comfrey (Symphytum officinale leaves resemble those of foxglove (Digitalis purpurea when the plant is not in bloom and, therefore, cardiac glycoside poisoning may occur when people confuse foxglove with comfrey. We report an outbreak of foxglove leaf poisoning following the use of alleged “comfrey” herbal tea. Nine patients were involved and initially presented with nausea, vomiting, diarrhea and dizziness. Significant cardiotoxicity developed later among the 3 patients who also had mild hyperkalemia. Peak serum digoxin concentration measured by immunoassay was elevated in all patients and ranged from 4.4 ng/mL to 139.5 ng/mL. Patients with severe cardiotoxicity were treated with temporary cardiac pacing. Moreover, 40–80 mg of digoxin-specific antibody therapy was given without any effect. All patients recovered uneventfully. Our report highlights the potential risk of misidentification of herbs; in this case, D. purpurea was mistaken for S. officinale. Physicians should be aware that cardiac glycoside poisoning could arise from such misidentification. Public education about the toxicity of D. purpurea poisoning may reduce the risk of misidentification and subsequent poisoning.

Increased Incidence and Altered Risk Demographics of Childhood Lead Poisoning: Predicting the Impacts of the CDC’s 5 µg/dL Reference Value in Massachusetts (USA)

Handler, Phoebe; Brabander, Daniel

2012-01-01

In May 2012, the CDC adopted a new sliding scale reference value for childhood lead poisoning, reducing the former 10 µg/dL benchmark by half. Using Massachusetts (MA) as a model state, we estimated the change in the population of 9–47 month-olds at risk for lead poisoning. We then examined the impact of the 5 µg/dL reference value on the demographic characteristics of lead risk in MA communities. We find that the new CDC benchmark will lead to a 1470% increase in childhood lead poisoning cases among 9–47 month-olds in MA, with nearly 50% of the examined communities experiencing an increased prevalence of lead poisoning. Further, the top 10 MA communities with BLLs ≥5 µg/dL have significantly fewer foreign-born residents and significantly larger white populations than the highest risk communities formerly identified by the MA Childhood Lead Poisoning Prevention Program. The CDC’s new 5 µg/dL lead poisoning benchmark will drastically increase the number of children with elevated BLLs and alter the distribution and demographics high-risk communities in MA.

The aim of this study was to assess the role of blood lactate levels at admission in carbon monoxide (CO)-poisoned patients for establishing severity of poisoning and short term prognosis. All cases of CO poisoning visited in the emergency department during the years 2012 and 2013 were retrieved from the hospital database. The concentration of COHb and lactate was assessed in arterial blood in all patients with suspected CO poisoning, along with the plasma concentration of troponin I (TnI). The control population for TnI results consisted in 125 blood donors. Twenty three (61%) out of 38 CO-poisoned patients underwent hyperbaric oxygen (HBO) treatment, and 10 (26%) were admitted to a hospital ward. A significant correlation was found between lactate and COHb (r=0.54; p99th percentile compared to 2% controls (p=0.003). The odds ratio for detectable TnI and TnI >99th percentile in CO-poisoned patients were 13.1 (p<0.001) and 7.6 (p=0.006), respectively. Initial blood lactate level may be useful for risk stratification of CO-poisoned patients, especially for predicting hospitalization. Copyright © 2014 The Canadian Society of Clinical Chemists.

Carbon monoxide poisoning (COP) causes hypoxic injury and inflammatory and immunological reactions in the brain and local organs including the pancreas. Therefore, it is plausible that COP may increase the risk for developing diabetes mellitus (DM), but studies on this possible association are limited. We conducted a nationwide study in Taiwan to fill the data gap. We used the Nationwide Poisoning Database and the Longitudinal Health Insurance Database 2000 to identify all COP patients diagnosed between 1999 and 2012 (the study cohort) and then construct a comparison cohort of patients without COP through matching at 1:3 by the index date and age. The risk for DM between the two cohorts was compared by following up until 2013. We also investigated the independent predictors for DM in all the patients. During the study period, 22,308 COP patients were identified, and 66,924 non-COP patients were included in the comparison cohort accordingly. Patients with COP had an increased risk for DM with an adjusted hazard ratio (AHR) of 1.92 (95% confidence interval [CI]: 1.79–2.06) after adjusting for age, sex, comorbidities, and monthly income, especially in the subgroups of age increased risk for DM was highest in the first month after COP (AHR= 3.38; 95% CI: 2.29–4.99) and lasted even after 4 years (AHR= 1.82; 95% CI: 1.62–2.04). We found that COP, older age, male sex, hypertension, hyperlipidemia, hyperuricemia, and low monthly income were independent predictors for DM. Intervention studies are needed to validate the results and delineate the detailed mechanisms. PMID:28969020

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].

Wong, Anselm; Graudins, Andis

2017-09-01

Paracetamol (acetaminophen) poisoning is the most common cause of acute liver failure in the developed world. A paracetamol treatment nomogram has been used for over four decades to help determine whether patients will develop hepatotoxicity without acetylcysteine treatment, and thus indicates those needing treatment. Despite this, a small proportion of patients still develop hepatotoxicity. More accurate risk predictors would be useful to increase the early detection of patients with the potential to develop hepatotoxicity despite acetylcysteine treatment. Similarly, there would be benefit in early identification of those with a low likelihood of developing hepatotoxicity, as this group may be safely treated with an abbreviated acetylcysteine regimen. To review the current literature related to risk prediction tools that can be used to identify patients at increased risk of hepatotoxicity. A systematic literature review was conducted using the search terms: "paracetamol" OR "acetaminophen" AND "overdose" OR "toxicity" OR "risk prediction rules" OR "hepatotoxicity" OR "psi parameter" OR "multiplication product" OR "half-life" OR "prothrombin time" OR "AST/ALT (aspartate transaminase/alanine transaminase)" OR "dose" OR "biomarkers" OR "nomogram". The search was limited to human studies without language restrictions, of Medline (1946 to May 2016), PubMed and EMBASE. Original articles pertaining to the theme were identified from January 1974 to May 2016. Of the 13,975 articles identified, 60 were relevant to the review. Paracetamol treatment nomograms: Paracetamol treatment nomograms have been used for decades to help decide the need for acetylcysteine, but rarely used to determine the risk of hepatotoxicity with treatment. Reported paracetamol dose and concentration: A dose ingestion >12 g or serum paracetamol concentration above the treatment thresholds on the paracetamol nomogram are associated with a greater risk of hepatotoxicity.

Methanol poisoning continues to be a serious public health issue in Taiwan, but very little work has been done to study the outcomes of methanol toxicity in the Asian population. In this study, we examined the value of multiple clinical variables in predicting mortality after methanol exposure. We performed a retrospective observational study on patients with acute poisoning who were admitted to the Chang Gung Memorial Hospital over a period of 9 years (2000-2008). Out of the 6,347 patients, only 32 suffered methanol intoxication. The demographic, clinical, laboratory, and mortality data were obtained for analysis. Most patients were middle aged (46.1±13.8 years), male (87.5%), and habitual alcohol consumers (75.0%). All the poisonings were from an oral exposure (96.9%), except for one case of intentionally injected methanol (3.1%). After a latent period of 9.3±10.1 hours, many patients began to experience hypothermia (50.0%), hypotension (15.6%), renal failure (59.4%), respiratory failure (50.0%), and consciousness disturbance (Glasgow coma scale [GCS] score 10.5±5.4). Notably, the majority of patients were treated with ethanol antidote (59.4%) and hemodialysis (58.1%). The remaining 41.6% of patients did not meet the indications for ethanol therapy. At the end of analysis, there were six (18.8%), 15 (46.9%), and eleven (34.4%) patients alive, alive with chronic complications, and dead, respectively. In a multivariate Cox regression model, it was revealed that the GCS score (odds ratio [OR] 0.816, 95% confidence interval [CI] 0.682-0.976) (P=0.026), hypothermia (OR 168.686, 95% CI 2.685-10,595.977) (P=0.015), and serum creatinine level (OR 4.799, 95% CI 1.321-17.440) (P=0.017) were significant risk factors associated with mortality. The outcomes (mortality rate 34.4%) of the Taiwanese patients subjected to intensive detoxification protocols were comparable with published data from other international poison centers. Furthermore, the analytical results indicate

Prevention is an essential aspect in paediatric poisonings, especially when recurrent episodes are detected. The aims of this article are to detect the recurrence rate for suspected poisoning in emergency consultations, as well as to identify the cases in which specific preventive measures are indicated, and to determine whether the creation of a specific item for recurrent episodes in the computerised medical records system facilitates its detection. A retrospective study was conducted on patients less than 18 years of age treated in the emergency room due to suspected poisoning during 2013 and 2014. Patients were divided according to the presence or absence of previous episodes. From January 2014, a specific item is present in the computerised medical records of the poisoned patient, where the history of previous episodes is registered. The preventive measures used between both groups were compared. A total of 731 consultations were recorded for suspected poisoning. A history of previous episodes was detected in 9% of cases. Medical injury reports and follow-up in outpatient clinics were more often performed in patients with recurrent episodes than in patients without them (28.8% vs 18.0%, P=.034, and 65.2% vs. 18.8%, P<.001, respectively). In 2013, the recurrence rate was 5.9% vs 12% in 2014 (P=.004). The recurrence rate observed is significant. Although preventive measures are more frequently indicated in these patients, their application is low. The creation of a specific item for recurrent episodes in a computerised medical records system facilitates their detection. Copyright © 2016 Asociación Española de Pediatría.

and symptoms resulting from poisoning from these plants are discussed. Medical treatment recommendations are made. Poisoning following ingestion or other forms of exposures to plants in New Zealand is relatively common, particularly among children. However, serious adverse reactions are comparatively rare. Accurate plant identification and details on the type of exposure can be important in assessing the likely risks. Effective medical management of these poisonings can be achieved by following the principles outlined in this review.

Using poison center exposure calls to predict methadone poisoning deaths.

Directory of Open Access Journals (Sweden)

Nabarun Dasgupta

Full Text Available PURPOSE: There are more drug overdose deaths in the Untied States than motor vehicle fatalities. Yet the US vital statistics reporting system is of limited value because the data are delayed by four years. Poison centers report data within an hour of the event, but previous studies suggested a small proportion of poisoning deaths are reported to poison centers (PC. In an era of improved electronic surveillance capabilities, exposure calls to PCs may be an alternate indicator of trends in overdose mortality. METHODS: We used PC call counts for methadone that were reported to the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS® System in 2006 and 2007. US death certificate data were used to identify deaths due to methadone. Linear regression was used to quantify the relationship of deaths and poison center calls. RESULTS: Compared to decedents, poison center callers tended to be younger, more often female, at home and less likely to require medical attention. A strong association was found with PC calls and methadone mortality (b=0.88, se=0.42, t=9.5, df=1, p<0.0001, R(2 =0.77. These findings were robust to large changes in a sensitivity analysis assessing the impact of underreporting of methadone overdose deaths. CONCLUSIONS: Our results suggest that calls to poison centers for methadone are correlated with poisoning mortality as identified on death certificates. Calls received by poison centers may be used for timely surveillance of mortality due to methadone. In the midst of the prescription opioid overdose epidemic, electronic surveillance tools that report in real-time are powerful public health tools.

The lack of nationwide public databases on poisoning in cattle makes it difficult to investigate this issue. Hence, we conducted an epidemiological study using the data on cattle poisoning provided by an insurance company (2000-2005), to determine the mortality rate due to poisoning in cattle in Spain and to assess the influence of the following variables: type of farming, age, sex, time of year, year and region. We observed a mortality rate of 23.25 per 100,000 animals in Spain with a higher rate in beef than dairy cattle (32.14 vs. 4.51 per 100,000 animals). There were also differences in the mortality rate between breeding cattle and future breeders, affecting dairy and beef cattle in a different way. In dairy cattle, we found differences between the years analysed. In beef cattle, the time of year with highest risk of poisoning was the last quarter (19.45 per 100,000 animals), while the lowest mortality rate was observed in the first quarter (1.33 per 100,000). There were pronounced differences between regions in beef cattle, differences being non-significant in dairy cattle. Lastly, in beef cattle, no differences were found between sexes. In summary, the mortality rate due to poisoning in cattle in Spain is low, and the risk of poisoning is determined by the farming system, animals’ stage of development, time of year and region.

Radiation Dose-Response Relationships and Risk Assessment

International Nuclear Information System (INIS)

Strom, Daniel J.

2005-01-01

The notion of a dose-response relationship was probably invented shortly after the discovery of poisons, the invention of alcoholic beverages, and the bringing of fire into a confined space in the forgotten depths of ancient prehistory. The amount of poison or medicine ingested can easily be observed to affect the behavior, health, or sickness outcome. Threshold effects, such as death, could be easily understood for intoxicants, medicine, and poisons. As Paracelsus (1493-1541), the 'father' of modern toxicology said, 'It is the dose that makes the poison.' Perhaps less obvious is the fact that implicit in such dose-response relationships is also the notion of dose rate. Usually, the dose is administered fairly acutely, in a single injection, pill, or swallow; a few puffs on a pipe; or a meal of eating or drinking. The same amount of intoxicants, medicine, or poisons administered over a week or month might have little or no observable effect. Thus, before the discovery of ionizing radiation in the late 19th century, toxicology ('the science of poisons') and pharmacology had deeply ingrained notions of dose-response relationships. This chapter demonstrates that the notion of a dose-response relationship for ionizing radiation is hopelessly simplistic from a scientific standpoint. While useful from a policy or regulatory standpoint, dose-response relationships cannot possibly convey enough information to describe the problem from a quantitative view of radiation biology, nor can they address societal values. Three sections of this chapter address the concepts, observations, and theories that contribute to the scientific input to the practice of managing risks from exposure to ionizing radiation. The presentation begins with irradiation regimes, followed by responses to high and low doses of ionizing radiation, and a discussion of how all of this can inform radiation risk management. The knowledge that is really needed for prediction of individual risk is presented

Assessing the need for communication training for specialists in poison information.

Effective communication has been shown to be essential to physician-patient communication and may be even more critical for poison control center (PCC) calls because of the absence of visual cues, the need for quick and accurate information exchange, and possible suboptimal conditions such as call surges. Professionals who answer poison control calls typically receive extensive training in toxicology but very little formal training in communication. An instrument was developed to assess the perceived need for communication training for specialists in poison information (SPIs) with input from focus groups and a panel of experts. Requests to respond to an online questionnaire were made to PCCs throughout the United States and Canada. The 537 respondents were 70% SPIs or poison information providers (PIPs), primarily educated in nursing or pharmacy, working across the United States and Canada, and employed by their current centers an average of 10 years. SPIs rated communication skills as extremely important to securing positive outcomes for PCC calls even though they reported that their own training was not strongly focused on communication and existing training in communication was perceived as only moderately useful. Ratings of the usefulness of 21 specific training units were consistently high, especially for new SPIs but also for experienced SPIs. Directors rated the usefulness of training for experienced SPIs higher for 5 of the 21 challenges compared to the ratings of SPIs. Findings support the need for communication training for SPIs and provide an empirical basis for setting priorities in developing training units.

Psychiatric comorbidity and its impact on mortality in patients who attempted suicide by paraquat poisoning during 2000-2010.

Directory of Open Access Journals (Sweden)

Chemin Lin

Full Text Available Paraquat poisoning is a lethal method of suicide used around the world. Although restricting its accessibility had been widely discussed, the underlying psychopathological mechanism of paraquat self-poisoning and its association with mortality have not yet been explicitly evaluated.We included all patients admitted to a tertiary general hospital in Taiwan between 2000 and 2010 following a suicide attempt by paraquat self-administration. Diagnoses were made upon psychiatric consultation based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV criteria. The risk of mortality was calculated by logistic regression with various psychiatric or medical covariates.The consultation-liaison psychiatry team assessed 157 patients who attempted suicide by paraquat poisoning. Mood disorders (54.0%, including dysthymic (26.7% and major depressive disorders (24.7%, were the most common psychiatric diagnoses among the self-poisoning patients. Among those who attempted suicide, 87 patients (58.0% died and dysthymic disorder (OR = 5.58, 95% CI: 1.13-27.69; p < 0.05 significantly increased the mortality risk after adjustment for relevant medical variables, including age, gender, severity index of paraquat poisoning (SIPP, and risk for respiratory failure.Awareness of comorbid psychiatric illnesses, especially dysthymic disorder, is vital in the prevention and treatment of suicide by paraquat poisoning.

Full Text Available Abstract Background Poisoning is a significant public health problem worldwide and is one of the most common reasons for visiting emergency departments (EDs, but factors that help to predict overall poisoning-related fatality have rarely been elucidated. Using 1512 subjects from a hospital-based study, we sought to describe the demographic and clinical characteristics of poisoning patients and to identify predictors for poisoning-related fatality. Methods Between January 2001 and December 2002 we prospectively recruited poisoning patients through the EDs of two medical centers in southwest Taiwan. Interviews were conducted with patients within 24 hours after admission to collect relevant information. We made comparisons between survival and fatality cases, and used logistic regressions to identify predictors of fatality. Results A total of 1512 poisoning cases were recorded at the EDs during the study period, corresponding to an average of 4.2 poisonings per 1000 ED visits. These cases involved 828 women and 684 men with a mean age of 38.8 years, although most patients were between 19 and 50 years old (66.8%, and 29.4% were 19 to 30 years. Drugs were the dominant poisoning agents involved (49.9%, followed by pesticides (14.5%. Of the 1512 patients, 63 fatalities (4.2% occurred. Paraquat exposure was associated with an extremely high fatality rate (72.1%. The significant predictors for fatality included age over 61 years, insufficient respiration, shock status, abnormal heart rate, abnormal body temperature, suicidal intent and paraquat exposure. Conclusion In addition to well-recognized risk factors for fatality in clinical settings, such as old age and abnormal vital signs, we found that suicidal intent and ingestion of paraquat were significant predictors of poisoning-related fatality. Identification of these predictors may help risk stratification and the development of preventive interventions.

Full Text Available Audience: This oral boards case is appropriate for all emergency medicine learners (residents, interns, and medical students. Introduction: Carbon monoxide (CO is a colorless and odorless gas that typically results from combustion. It binds hemoglobin, dissociating oxygen, causing headache, weakness, confusion and possible seizure or coma. Pulse oxygen levels may be falsely elevated. Practitioners should maintain a high index of suspicion for carbon monoxide poisoning. If caught early CO poisoning is reversible with oxygen or hyperbaric oxygen therapy. Objectives: The learner will assess a patient with altered mental status and weakness, ultimately identifying that the patient has carbon monoxide poisoning. The learner will treat the patient with oxygen and admit/transfer the patient for hyperbaric oxygenation. Method: Oral boards case

Full Text Available Aim: Carbon monoxide (CO is often referred to as the “silent killer” because its victims cannot see it, smell it or taste it. CO is responsible for a large percentage of the accidental poisonings and deaths reported throughout the world. CO poisoning therefore is considered a serious global health threat. The aim of the present study was to describe the cases of CO poisoning in a rural areas of Adana, Turkey between 2002 and 2015 based on data collected from incident reports. Methods: The cases of accidental CO poisoning were statistically analyzed. During that period, 74 incidents occurred and 154 people were poisoned by accidental CO poisoning. Results: The results of this analysis indicate that men and adults aged ≥65 years were more likely to die from CO poisoning than others. The number of CO poisoning cases was highest during the heating season. The majority (72% of poisoning resulting in hospitalization with a life-threatening condition or death occurred within the home. Conclusion: CO poisoning is a serious danger. People must be informed about this hazard. By educating risk groups about the dangers of CO poisoning, it is possible to save many lives as well as reduce the health risks.

Epidemiological data on food poisonings in Japan focused on Salmonella, 1998-2004.

In Japan, the numbers and cases of food poisonings must be reported as required by the Food Sanitation Law. This paper focuses on Salmonella, one of the leading food-borne pathogens in Japan, and it analyses the reported food poisoning data to assess the nature of Salmonella-associated food-borne disease. Obviously, these data do not exactly reflect the burden of food-borne illness associated with Salmonella; however, trends in Salmonella food poisoning and implicated foods could be identified for the purpose of setting priorities to mitigate the risk of food-borne salmonellosis. Summary information of Salmonella food poisoning investigation reports submitted by health departments of all prefectures and major cities between January 1998 and December 2004 was analysed. Both the number of reports and the cases of Salmonella food poisoning decreased drastically from 1999 (831 Salmonella food poisoning reports with 11,877 cases) to 2001 (265 reports with 7011 cases), increased in 2002, and then decreased again in 2003 and 2004 (231 reports with 3793 cases in 2004). About 80% of the Salmonella food poisoning reports and cases were associated with Salmonella enteritidis throughout the study period. Food vehicles were identified in 17-25% of the Salmonella food poisoning reports. Between 1998 and 2002, 45-60% of the Salmonella food poisoning cases were associated with eggs; however, the percentage dropped to 24.2% in 2003. The number of Salmonella food poisoning reports associated with beef, pork and poultry meat, and raw vegetables, which have been frequently reported in other countries, were very limited. Among the identified locations of disease break outs, 30-49% occurred in restaurant settings and the percentage of cases in restaurants increased during the study period. Thirteen to 41% of the Salmonella food poisoning cases occurred within the home, and the percentage declined. Phage types 1 and 4 were the predominant S. enteritidis isolated in 1998 and 1999; however

Kerosene oil poisoning is one of common presentations to emergency departments among children in rural territories of developing countries. This study aimed to describe clinical manifestations, reasons for delayed presentations, harmful first aid practices, complications, and risk factors related to kerosene oil poisoning among children in rural Sri Lanka. This multicenter study was conducted in North-Central province of Sri Lanka involving all in-patient children with acute kerosene oil poisoning. Data were collected over seven years from thirty-six hospitals in the province. Data collection was done by pretested, multistructured questionnaires and a qualitative study. Male children accounted for 189 (60.4%) while 283 (93%) children were below five years. The majority of parents belonged to farming community. Most children ingested kerosene oil in home kitchen. Mortality rate was 0.3%. Lack of transport facilities and financial resources were common reasons for delayed management. Hospital transfer rate was 65.5%. Thirty percent of caregivers practiced harmful first aid measures. Commonest complication was chemical pneumonitis. Strongest risk factors for kerosene oil poisoning were unsafe storage, inadequate supervision, and inadequate house space. Effect of safe storage and community education in reducing the burden of kerosene oil poisoning should be evaluated. Since many risk factors interact to bring about the event of poisoning in a child, holistic approaches to community education in rural settings are recommended.

Full Text Available Abstract Background Delayed neuropsychological sequelae (DNS commonly occur after recovery from acute carbon monoxide (CO poisoning. The preventive role and the indications for hyperbaric oxygen therapy in the acute setting are still controversial. Early identification of patients at risk in the Emergency Department might permit an improvement in quality of care. We conducted a retrospective study to identify predictive risk factors for DNS development in the Emergency Department. Methods We retrospectively considered all CO-poisoned patients admitted to the Emergency Department of Careggi University General Hospital (Florence, Italy from 1992 to 2007. Patients were invited to participate in three follow-up visits at one, six and twelve months from hospital discharge. Clinical and biohumoral data were collected; univariate and multivariate analysis were performed to identify predictive risk factors for DNS. Results Three hundred forty seven patients were admitted to the Emergency Department for acute CO poisoning from 1992 to 2007; 141/347 patients participated in the follow-up visit at one month from hospital discharge. Thirty four/141 patients were diagnosed with DNS (24.1%. Five/34 patients previously diagnosed as having DNS presented to the follow-up visit at six months, reporting a complete recovery. The following variables (collected before or upon Emergency Department admission were associated to DNS development at one month from hospital discharge in the univariate analysis: CO exposure duration >6 hours, a Glasgow Coma Scale (GCS score Conclusions Our study identified several potential predictive risk factors for DNS. Treatment algorithms based on an appropriate risk-stratification of patients in the Emergency Department might reduce DNS incidence; however, more studies are needed. Adequate follow-up after hospital discharge, aimed at correct recognition of DNS, is also important.

Acute pesticide poisoning and pesticide registration in Central America

Wesseling, Catharina; Corriols, Marianela; Bravo, Viria

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

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

Accidental poisoning with detomidine and butorphanol.

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.

Sodium monofluoroacetate (1080) risk assessment and risk communication

International Nuclear Information System (INIS)

Eason, Charles

2002-01-01

Sodium monofluoroacetate (1080) is a vertebrate pesticide widely used for possum control in New Zealand. Fluoroacetate is also a toxic component of poisonous plants found in Australia, South Africa, South America, and India. Because of its importance and effectiveness in pest control and the highly toxic nature of this compound, its acute sub-lethal and target organ toxicity have been extensively studied. In relation to its use as a pesticide its environmental fate, persistence, non-target impacts and general toxicology have been and continue to be extensively studied. Toxic baits must be prepared and used with extreme care, otherwise humans, livestock, and non-target wildlife will be put at risk. The high risk of secondary poisoning of dogs is a cause for concern. 1080 acts by interfering with cellular energy production. Possums die from heart failure, usually within 6-18 h of eating baits. Long-term exposure to sub-lethal doses can have harmful effects and strict safety precautions are enforced to protect contractors and workers in the bait manufacturing industry. Considerable care is taken when using 1080 to ensure that the risks of using it are outweighed by the ecological benefits achieved from its use. When its use is controversial, risk communicators must take care not to trivialise the toxicity of the compound. The benefits of 1080 use in conservation, pest control, and disease control should be weighed up alongside the risks of using 1080 and other techniques for pest control

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.

Nuclear fuel saving assessment of poison-free control in LWRs [light water reactors

International Nuclear Information System (INIS)

Abu-Zaied, G.

1988-01-01

If neutron losses to control absorbers are to be eliminated, an alternative reactivity control system has to be introduced. Due to improved neutron economy, the fuel utilization of these other alternatives is better than for a conventional poison-controlled PWR [pressurized water reactor]. It is the objective in this work to assess the uranium savings attributable to reactivity control without poison. An investigation into the savings due to the elimination of PWR control by neutron capture has been carried out. The most important finding was that up to a 30% savings in natural uranium can be achieved if fuel to moderator ratio, V f /V m , of SSC [spectral-shift-control] core at EOC [end of cycle] is similar to the standard core V f /V m

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.

Neuropsychology of thallium poisoning

McMillan, T; Jacobson, R; Gross, M

1997-01-01

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.

Cortinovis, Cristina; Caloni, Francesca

2015-12-08

Alkaloids, nitrogen-containing secondary plant metabolites, are of major interest to veterinary toxicology because of their occurrence in plant species commonly involved in animal poisoning. Based on epidemiological data, the poisoning of cattle and horses by alkaloid-containing plants is a relatively common occurrence in Europe. Poisoning may occur when the plants contaminate hay or silage or when forage alternatives are unavailable. Cattle and horses are particularly at risk of poisoning by Colchicum autumnale (meadow saffron), Conium maculatum (poison hemlock), Datura stramonium (jimson weed), Equisetum palustre (marsh horsetail), Senecio spp. (ragwort and groundsel) and Taxus baccata (European yew). This review of poisonous alkaloid-containing plants describes the distribution of these plants, conditions under which poisoning occurs, active toxic principles involved and subsequent clinical signs observed.

To investigate the efficacy of the one-piece ostomy bags for severe organophosphate poisoned patients after catharsis. Sixty cases of severe organophosphate poisoned patients who were given rhubarb catharsis after thorough nasal lavage were divided into two groups. The observation group used the one-piece ostomy bags whilst the control group used the disposable changing mats. The perineal skin changes, average daily hours of care, and cost of care rates were compared between the two groups. The rates of perineal skin changes were lower in the observation group than the control group (p ostomy bag in poisoned patients after the catharsis can prevent the risk of nursing by protecting and promoting the care quality, reducing the nursing workload and improving their work efficiency. It can enhance the nurses' self-esteem, reduce patients' expenses and provide an objective basis for assessing the treatments.

Paraquat poisoning causes multiple organ injury and high mortality due to severe toxicity and lack of effective treatment. Xuebijing (XBJ) injection, a traditional Chinese medicine preparation of five Chinese herbs (Radix Salviae Miltiorrhiae, Rhizoma Chuanxiong, Flos Carthami, Angelica Sinensis and Radix Paeoniae Rubra), has an anti-inflammatory effect and is widely used in the treatment of sepsis. This retrospective study was designed to evaluate the effects of XBJ combined with conventional therapy on mortality risk of patients with acute paraquat poisoning. Out of 68 patients, 27 were treated with conventional therapy (control group) and 41 were treated with intravenous administration of XBJ (100 ml, twice a day, up to 7 days) plus conventional therapy (XBJ group). Vital organ function, survival time within 28 days and adverse events during the treatment were reviewed. Results indicated that XBJ treatment significantly increased median survival time among patients ingesting 10-30 ml of paraquat (P=0.02) compared with the control group. After adjustment for covariates, XBJ treatment was associated significantly with a lower mortality risk (adjusted HR 0.242, 95% CI 0.113 to 0.516, P=0.001) compared with the control group. Additionally, compared with Day 1, on Day 3 the value of PaO2/FiO2 was significantly decreased, and the values of serum alanine aminotransferase, creatinine and troponin T were significantly increased in the control group (all Ptreatment is associated with decreased mortality risk of patients with moderate paraquat poisoning, which may be attributed to improved function of vital organs with no severe adverse events.

Toad poisoning in three dogs: case reports

Directory of Open Access Journals (Sweden)

CM Barbosa

2009-01-01

Full Text Available Toad poisoning is frequent in dogs, but has been infrequently addressed in published case reports and review articles. Dogs can be poisoned when they bite a toad or otherwise ingest the venom. The venom effects manifest soon after the accident, since the toxin is rapidly absorbed by the mucous membrane of the digestive system. Hospital records of three dogs, diagnosed with toad poisoning, were retrospectively reviewed from January 2005 to July 2007. Poisoned dogs may present only local irritation or systemic signs in the gastrointestinal, cardiac and neurological systems. All three cases presented herein had clinical signs of gastrointestinal alterations including vomiting, sialorrhea and diarrhea. Two dogs developed abnormal cardiac rhythm and two exhibited neurological signs. A poisoned animal requires emergency care and symptomatic therapy with intense monitoring of its clinical parameters. Although there have been reports on the low mortality of dogs poisoned by toads, one animal died even after appropriate therapy. The severity of clinical signs and the risk of death must be considered by the veterinarian.

2017-01-01

The aim of this study was to assess cardiological manifestations of carbon monoxide (CO) poisoning. Background/introduction: Carbon monoxide intoxication is one of the most important toxicological causes of morbidity and mortality worldwide. Early clinical manifestation of CO poisoning is cardiotoxicity. We enrolled 75 patients (34 males and 41 females, mean age 37.6 ± 17.7 y/o) hospitalized due to CO poisoning. Laboratory tests including troponin I, blood pressure measurements, HR and electrocardiograms (ECG) were collected. Pach's scale scoring and grading system was used to establish severity of poisoning. Grade of poisoning is positively correlated with troponin I levels and systolic blood pressure. Moreover, troponin levels are significantly correlated with exposition time, lactates and are higher in tachycardiac, hypertensive and positive ECG subpopulations. COHb levels are indicative of exposure but do not correlate with grade of poisoning. The main cause of CO poisoning were bathroom heaters - 83%, only 11% of examined intoxicated population were equipped with CO detectors. Complex cardiological screening covering troponin levels, ECG, blood pressure and heart rate measurements as well as complete blood count with particular attention to platelet parameters should be performed in each case where CO intoxication is suspected. More emphasis on education on CO poisoning is needed.

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.

Each year, more than 200 people in the United States die from carbon monoxide (CO) poisoning. Poisoning has occurred at motels, hotels, and resorts. Congressional mandate requires smoke alarms in all guest rooms; however, smoke alarms do not detect CO. Data on patients poisoned at hotels, motels, and resorts were evaluated at a hyperbaric medicine service. In 2005, legal databases and online news databanks were searched to discover additional incidents. Only victims evaluated in hospitals or declared dead at the scene were included. Cases of intentional poisoning and poisoning from fires were excluded. Between 1989 and 2004, 68 incidents of CO poisoning occurring at hotels, motels, and resorts were identified, resulting in 772 accidentally poisoned: 711 guests, 41 employees or owners, and 20 rescue personnel. Of those poisoned, 27 died, 66 had confirmed sequelae, and 6 had sequelae resulting in a jury verdict. Lodging-operated, faulty room heating caused 45 incidents, pool/spa boilers 16, CO entrained from outdoors 5, and unreported sources caused 2 incidents. Public verdicts have averaged $4.8 million per incident (range, $1 million to $17.5 million). Poisoning occurred at hotels of all classes. Despite these incidents, most properties did not install CO alarms, and requirements for CO alarms at hotels, motels, and resorts are rare. Guests of motels, hotels, and resorts remain at risk for injury or death from CO poisoning. Measures to prevent CO poisoning of guests and employees of the lodging industry should be evaluated.

Ayurveda, Indian traditional system of medicine, is practiced commonly in South East Asia and in many parts of the world. Many ayurvedic drugs contain heavy metals and may lead to metal toxicity. Of these, chronic lead poisoning is the most common. Chronic arsenic poisoning following the use of ayurvedic medication, though reported, is rare. We describe three patients who presented with features of chronic arsenic poisoning following prolonged ayurvedic medication use. The diagnosis of chronic arsenic poisoning was confirmed by high arsenic levels in the blood, urine, hair, and nails in all the three patients and in ayurvedic drug in two patients. The ayurvedic medication was discontinued and treatment with D-penicillamine started. At 6 months after treatment, blood arsenic levels returned to normal with clinical recovery in all of them. Arsenic poisoning following ayurvedic medication is much less common than lead poisoning, though mineral ayurvedic medicines may lead to it. We used D-penicillamine as chelator and all of them recovered. Whether withdrawal of medication alone or D-penicillamine also played a role in recovery is unclear and needs to be assessed.

A free webPOISONCONTROL app allows the public to determine the appropriate triage of poison ingestions without calling poison control. If accepted and safe, this alternative expands access to reliable poison control services to those who prefer the Internet over the telephone. This study assesses feasibility, safety, and user-acceptance of automated online triage of asymptomatic, nonsuicidal poison ingestion cases. The user provides substance name, amount, age, and weight in an automated online tool or downloadable app, and is given a specific triage recommendation to stay home, go to the emergency department, or call poison control for further guidance. Safety was determined by assessing outcomes of consecutive home-triaged cases with follow-up and by confirming the correct application of algorithms. Case completion times and user perceptions of speed and ease of use were measures of user-acceptance. Of 9256 cases, 73.3% were triaged to home, 2.1% to an emergency department, and 24.5% directed to call poison control. Children younger than 6 years were involved in 75.2% of cases. Automated follow-up was done in 31.2% of home-triaged cases; 82.3% of these had no effect. No major or fatal outcomes were reported. More than 91% of survey respondents found the tool quick and easy to use. Median case completion time was 4.1 minutes. webPOISONCONTROL augments traditional poison control services by providing automated, accurate online access to case-specific triage and first aid guidance for poison ingestions. It is safe, quick, and easy to use. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

Occupational carbon monoxide poisoning in the State of Washington, 1994-1999.

Science.gov (United States)

Lofgren, Don J

2002-04-01

Carbon monoxide poisonings continue to be significant and preventable for a number of work operations. This study assesses occupational carbon monoxide morbidity and mortality for the state of Washington based on a review of workers' compensation records for the years 1994-1999. The study characterizes sources, industries, and causative factors, and further attempts to identify work operations most at risk. Records were identified by both injury source and diagnostic codes. The study limits itself to non-fire-related carbon monoxide poisonings and primarily those from acute exposure. A decline in the number of claims was not evident, but the number of incidents per year showed a slight decline. Carbon monoxide poisonings were found to occur throughout all types of industries. The greatest number of claims was found in agriculture, followed by construction and wholesale trade, with these three accounting for more than half the claims and nearly half of the incidents. The more severe poisonings did not necessarily occur in industries with the greatest number of incidents. The major source for carbon monoxide poisoning was forklift trucks, followed by auto/truck/bus, portable saws, and more than 20 other sources. Fruit packing and storage had the highest number of incidents mostly due to fuel-powered forklift activity, with nearly half of the incidents occurring in cold rooms. Adverse health effects as measured by carboxyhemoglobin, hyperbaric oxygen treatment, unconsciousness, and number and cost of claims were indexed by source. Though several specific work operations were identified, the episodic nature of carbon monoxide poisonings, as well as the diverse industries and sources, and the opportunity for a severe poisoning in any number of operations, poses challenges for effective intervention.

2009-01-01

Quebec launched a public health campaign for the Montreal region to prevent carbon monoxide poisoning. The objectives of the campaign were to communicate the dangers of carbon monoxide poisoning, its potential sources, its effects on public health, and the means to prevent poisoning. Its purpose was to inform the public of the risks and strategies to be used in case of carbon monoxide poisoning and to lay out the merits of household carbon monoxide alarms. The communication was done by way of the media, in cooperation with community organizations and school boards. Other tools used in the campaign included the Internet, flyers and press releases. A poll taken in 2008 showed that 59 per cent of the respondents had one or more sources for carbon monoxide in their homes, including fireplaces, and that 28 per cent had a functioning alarm for carbon monoxide detection. A future survey will be held to follow-up on the evolution of the campaign. The development of various activities will help decrease the risk of carbon monoxide poisoning. tabs., figs.

Histamine fish poisoning revisited.

Science.gov (United States)

Lehane, L; Olley, J

2000-06-30

Histamine (or scombroid) fish poisoning (HFP) is reviewed in a risk-assessment framework in an attempt to arrive at an informed characterisation of risk. Histamine is the main toxin involved in HFP, but the disease is not uncomplicated histamine poisoning. Although it is generally associated with high levels of histamine (> or =50 mg/100 g) in bacterially contaminated fish of particular species, the pathogenesis of HFP has not been clearly elucidated. Various hypotheses have been put forward to explain why histamine consumed in spoiled fish is more toxic than pure histamine taken orally, but none has proved totally satisfactory. Urocanic acid, like histamine, an imidazole compound derived from histidine in spoiling fish, may be the "missing factor" in HFP. cis-Urocanic acid has recently been recognised as a mast cell degranulator, and endogenous histamine from mast cell degranulation may augment the exogenous histamine consumed in spoiled fish. HFP is a mild disease, but is important in relation to food safety and international trade. Consumers are becoming more demanding, and litigation following food poisoning incidents is becoming more common. Producers, distributors and restaurants are increasingly held liable for the quality of the products they handle and sell. Many countries have set guidelines for maximum permitted levels of histamine in fish. However, histamine concentrations within a spoiled fish are extremely variable, as is the threshold toxic dose. Until the identity, levels and potency of possible potentiators and/or mast-cell-degranulating factors are elucidated, it is difficult to establish regulatory limits for histamine in foods on the basis of potential health hazard. Histidine decarboxylating bacteria produce histamine from free histidine in spoiling fish. Although some are present in the normal microbial flora of live fish, most seem to be derived from post-catching contamination on board fishing vessels, at the processing plant or in the

Childhood lead poisoning in a Somali refugee resettlement community in New Hampshire.

Despite the gradual decrease in childhood lead poisoning in the United States, the risk for lead poisoning among African refugee children who resettle in the United States remains elevated. Communication methods implemented by resettlement agencies in the public health system for preventing childhood lead poisoning in this at-risk population warrant further investigation. We utilized structured interviews with key stakeholders (resettlement agencies, social service agencies developed by African refugees and resettled Somali refugees) involved in the refugee resettlement process to (1) describe the agency's role in the refugee resettlement process; (2) examine communication methods utilized and barriers experienced by the public health system in reference to childhood lead poisoning; (3) describe the refugee population's perception of childhood lead poisoning; (4) examine general challenges experienced by the public health system and the refugee population during the resettlement process; and (5) describe stakeholders' recommendations to improve health communication efforts. Based on our findings, we propose that communities are important determinants in health-related problems for refugee populations. Each community has its own environment and public health system that interacts with each other to influence health risks and risk perceptions of its populations. We advocate that understanding a community's ecology and implementing a culture-centered approach is essential for the public health system to help educate and prevent communication inequalities and health disparities among an at-risk African refugee population. This action can reduce a population's resistance to communication and help build a community's capacity to address a persistent public health problem, such as childhood lead poisoning.

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.

Traditional chinese medicine Xuebijing treatment is associated with decreased mortality risk of patients with moderate paraquat poisoning.

Full Text Available Paraquat poisoning causes multiple organ injury and high mortality due to severe toxicity and lack of effective treatment. Xuebijing (XBJ injection, a traditional Chinese medicine preparation of five Chinese herbs (Radix Salviae Miltiorrhiae, Rhizoma Chuanxiong, Flos Carthami, Angelica Sinensis and Radix Paeoniae Rubra, has an anti-inflammatory effect and is widely used in the treatment of sepsis. This retrospective study was designed to evaluate the effects of XBJ combined with conventional therapy on mortality risk of patients with acute paraquat poisoning. Out of 68 patients, 27 were treated with conventional therapy (control group and 41 were treated with intravenous administration of XBJ (100 ml, twice a day, up to 7 days plus conventional therapy (XBJ group. Vital organ function, survival time within 28 days and adverse events during the treatment were reviewed. Results indicated that XBJ treatment significantly increased median survival time among patients ingesting 10-30 ml of paraquat (P=0.02 compared with the control group. After adjustment for covariates, XBJ treatment was associated significantly with a lower mortality risk (adjusted HR 0.242, 95% CI 0.113 to 0.516, P=0.001 compared with the control group. Additionally, compared with Day 1, on Day 3 the value of PaO2/FiO2 was significantly decreased, and the values of serum alanine aminotransferase, creatinine and troponin T were significantly increased in the control group (all P<0.05, but these values were significant improved in the XBJ group (all P<0.05. Only one patient had skin rash with itch within 30 minutes after injection and no severe adverse events were found in the XBJ group. In conclusion, XBJ treatment is associated with decreased mortality risk of patients with moderate paraquat poisoning, which may be attributed to improved function of vital organs with no severe adverse events.

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. A large-scale study of the effectiveness

Common causes of poisoning: etiology, diagnosis and treatment.

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.

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.

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

The role of poison control centers in CBRN incidents

International Nuclear Information System (INIS)

Borron, S. W.; Haynes, J.; Young, P.

2009-01-01

Poison Control Centers (PCCs) have historically played a limited, parallel role in management of CBRN incidents; they are frequently called for advice by the public or health care providers when such incidents occur, but in many cases are not considered an integral part of the CBRN disaster emergency response team, lacking a 'place' in the Incident Command Structure (ICS). This is unfortunate, as PCCs represent an important public health resource. The roughly 60 centers in the U.S. are available 24/7, 365 days/year. Telephones are manned by professionals, including pharmacists and nurses with additional specialized training in poisoning response. PCC medical directors are generally trained in Emergency Medicine, Pediatrics or Preventive Medicine, with subspecialty training in Medical Toxicology. Many toxicologists attend specialized training in the radiation emergency management at REAC/TS. PCCs have extensive databases for poisoning management coupled with GIS surveillance. This combination of expertise and information renders PCCs well prepared to advice on decontamination and treatment of CBRN-contaminated victims. Their toxicology expertise allows their participation in risk assessment. PCCs are highly trusted by the community, enhancing their role in risk communication. We recently initiated a program that provides guidance on activation of PCCs by the Region 6 Regional Response Team (RRT6), Co-Chaired by the US Environmental Protection Agency (EPA) and the US Coast Guard, serving as the federal component of the National Response System for the states of Arkansas, Louisiana, New Mexico, Oklahoma, and Texas. The program will be described, with emphasis on how PCCs may work within ICS.(author)

Scombroid fish poisoning: an overlooked marine food poisoning.

Wu, M L; Yang, C C; Yang, G Y; Ger, J; Deng, J F

1997-08-01

Scombroid fish poisoning is a food-borne chemical intoxication caused by certain spoiled fish that contain a large amount of histamine and some biogenic diamines. It has gradually become a world-wide medical problem and probably is the most common cause of fish poisoning. As the data on the incidents of scombroid fish poisoning in Taiwan remains scarce, we report 2 incidents of scombroid fish poisoning in Northern Taiwan. We collected data of the 2 outbreaks of suspected fish poisoning which were reported to us in 1996. An epidemiological investigation was undertaken. Questionnaire interviews were given to persons who ate lunch in the same cafeteria in outbreak 2. The leftover fish were sent for species identification and toxin analysis. The first incident involving 4 women occurred in March 1996. All cases experienced flush, dizziness, blurred vision and skin rashes after eating lunch. A non-scombroid fish of Makaira with histamine levels as high as 84.13 mg/100 g flesh was implicated in this incident. In August 1996, another incident involving some cases who ate lunch at the same cafeteria were investigated. A total of 146 questionnaires were distributed with a return of 132 questionnaires (90.4%). Fifty-five employees reported positive signs or symptoms; 48 persons who ate fish and 7 women who did not eat fish were ill. Fish was the only food associated with the illness with an attack rate of 73.8% (p < 0.001). The incriminated fish was later identified as a scombroid fish of Euthynnus with a histamine content of 271.9 mg/100 g flesh in 1 leftover piece and 118.5 mg/100 g flesh in another piece. Most cases in these 2 outbreaks received treatment with antihistamines and had rapid and complete recovery. The diagnosis of scombroid fish poisoning could be misdiagnosed as food allergy or bacterial food poisoning if physicians are not aware of such poisoning. The nonspecific but characteristic symptomatology of histamine food poisoning and previous consumption of fish

Full Text Available Abstract Background Suicide is an important social tragic phenomenon which occurs by different tools or methods in different communities. Considering deliberate poisoning as a common and important method in Ilam province for suicide, the present study was launched to epidemiologically assess committing suicide in Ilam province, Iran, based on intentional poisoning. Methods By a retrospective study, all the recorded data associated with intentional poisoning suicide in Ilam Province during 1993–2013 were analyzed. All the demographic variables and the suicides’ outcomes were analyzed using the Chi-Square test, and the univariate and multivariate logistic regression models. Results Totally, 6794 cases of suicide (annual incidence rate of 87.28/ 100, 000 associated with poisoning were evaluated. The incidence rate of suicide attempts was 84.63/ 100, 000 (94.51 in female and 74.98 in male and the incidence rate of completed suicide was 2.17/ 100, 000 (1.94 in female and 2.40 in male. Also, the highest rates of attempted and completed suicide (annual incidence rate of 172.42 and 4.14, respectively were attributed to the age group of 15–24 year. Conclusion Females had a greater tendency to commit suicide by poisoning, and the lower level of education, the age group of 15–24 years and single individuals were more associated with suicide using poisonings. The incidence of attempted suicide in females and completed suicide in males was higher in this method. Considering the high rate of suicide by poisoning, further attention and supervision on the sale and reserve of drugs and poisons is necessary. Meanwhile, it seems that due to momentary emotions during the pubertal stage, the risk of committing suicide is increased especially among unemployed individuals; therefore, performing an extensive psychotherapy intervention is needed in the societies with younger populations.

The aim of the study was to compare the hospital management and direct costs of self-poisoning in six United Kingdom hospitals and to investigate whether hospital management influences outcome. This was a prospective descriptive study carried out at three teaching hospitals and three district general hospitals in North West England on adults (aged 16 or over) presenting to the study centres with deliberate self-poisoning over a 5-month period. Data were based on demographic and clinical characteristics, management of the current episode, direct costs and repetition of self-poisoning within 12 weeks of index episode. There were 1778 episodes of self-poisoning during the study period. There were marked differences in management between centres. There was a fivefold difference in the rate of admission to a medical bed (16.5%-81.3%), and a twofold difference in the rate of psychosocial assessment (28.5%-57.7%). These differences remained after adjustment for demographic and clinical factors. Hospital costs per episode varied from pound 228 to pound 422 and repetition rate ranged from 10% to 16%. Psychosocial assessment was associated with a twofold reduction in the risk of repetition. The marked variability of services for self-poisoning continue. It seems likely that this is having a detrimental effect on patient outcomes. Large scale intervention studies are required to inform both clinical practice and service provision.

The National Poison Data System (NPDS) is a database and surveillance system for US poison centers (PCs) call data. The Centers for Disease Control and Prevention (CDC) and American Association of Poison Control Centers (AAPCC) use NPDS to identify incidents of potential public health significance. State health departments are notified by CDC of incidents identified by NPDS to be of potential public health significance. Our objective was to describe the public health impact of CDC's notifications and the use of NPDS data for surveillance. We described how NPDS data informed three public health responses: the Deepwater Horizon incident, national exposures to laundry detergent pods, and national exposures to e-cigarettes. Additionally, we extracted survey results of state epidemiologists regarding NPDS incident notification follow-up from 1 January 2015 to 31 December 2016 to assess current public health application of NPDS data using Epi Info 7.2 and analyzed data using SAS 9.3. We assessed whether state health departments were aware of incidents before notification, what actions were taken, and whether CDC notifications contributed to actions. NPDS data provided evidence for industry changes to improve laundry detergent pod containers safety and highlighted the need to regulate e-cigarette sale and manufacturing. NPDS data were used to improve situational awareness during the 2010 Deepwater Horizon oil spill. Of 59 health departments and PCs who responded to CDC notifications about anomalies (response rate = 49.2%), 27 (46%) reported no previous awareness of the incident, and 20 (34%) said that notifications contributed to public health action. Monitoring NPDS data for anomalies can identify emerging public health threats and provide evidence-based science to support public health action and policy changes.

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

Science.gov (United States)

Ogada, Darcy L

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.

Case definitions for human poisonings postulated to palytoxins exposure.

A series of case reports and anecdotal references describe the adverse effects on human health ascribed to the marine toxin palytoxin (PLTX) after different exposure routes. They include poisonings after oral intake of contaminated seafood, but also inhalation and cutaneous/systemic exposures after direct contact with aerosolized seawater during Ostreopsis blooms and/or through maintaining aquaria containing cnidarian zoanthids. The symptoms commonly recorded during PLTX intoxication are general malaise and weakness, associated with myalgia, respiratory effects, impairment of the neuromuscular apparatus and abnormalities in cardiac function. Systemic symptoms are often recorded together with local damages whose intensity varies according to the route and length of exposure. Gastrointestinal malaise or respiratory distress is common for oral and inhalational exposure, respectively. In addition, irritant properties of PLTX probably account for the inflammatory reactions typical of cutaneous and inhalational contact. Unfortunately, the toxin identification and/or quantification are often incomplete or missing and cases of poisoning are indirectly ascribed to PLTXs, according only to symptoms, anamnesis and environmental/epidemiological investigations (i.e. zoanthid handling or ingestion of particular seafood). Based on the available literature, we suggest a "case definition of PLTX poisonings" according to the main exposure routes, and, we propose the main symptoms to be checked, as well as, hemato-clinical analysis to be carried out. We also suggest the performance of specific analyses both on biological specimens of patients, as well as, on the contaminated materials responsible for the poisoning. A standardized protocol for data collection could provide a more rapid and reliable diagnosis of palytoxin-poisoning, but also the collection of necessary data for the risk assessment for this family of toxins.

There are few Spanish studies on acute poisoning in the elderly despite the associated risk factors of this group of patients. 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.

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.

Full Text Available Paracetamol is one of the most commonly used analgesics and antipyretics available without limits as preparations of the OTC group (over the counter drugs. Overdose and poisoning with this drug always brings about the risk of acute hepatic failure. The objective of the study was a retrospective evaluation of patients hospitalized in the Paediatric Clinic during the period 2004–2012 due to poisoning with paracetamol.The analysis covered 44 patients hospitalized in the Paediatric Clinic during 2004–2012 due to poisoning with paracetamol. Patients were divided into three groups: intentional poisonings, accidental poisonings, and drug overdose.During the period of the study, 44 patients aged 2.1–17.1, poisoned with paracetamol, were hospitalized. Among these patients there were 30 (68.2% cases of intentional poisonings, 10 (22.7% of accidental poisonings, and only 4 patients (9.1% were children hospitalized after a paracetamol overdose. The majority of patients in all groups were females (93.3%.Paracetamol intoxication may occur after exceeding a single allowable dose, in the case of intentional poisoning, more rarely after exceeding the daily dose, in the case of intense pain complaints, or in the treatment of persistent fever.Based on the analysis performed, an increase was observed in the frequency of poisoning with paracetamol, especially intentional poisoning. Unlimited access to paracetamol as an OTC drug should be reconsidered.

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.

Ciguatera and scombroid fish poisonings are common causes of fish-related foodborne illness in the United States; however, existing surveillance systems underestimate the overall human health impact. This study aimed to describe existing data on ciguatera and scombroid fish poisonings from outbreak and poison control center reports and to estimate the overall number of ciguatera and scombroid fish-poisoning illnesses, hospitalizations, and deaths in the United States. We analyzed outbreak data from the Foodborne Disease Outbreak Surveillance Systems (FDOSS) from 2000 to 2007 and poison control center call data from the National Poison Data System (NPDS) from 2005 to 2009 for reports of ciguatera and scombroid fish poisonings. Using a statistical model with many inputs, we adjusted the outbreak data for undercounting due to underreporting and underdiagnosis to generate estimates. Underreporting and underdiagnosis multipliers were derived from the poison control call data and the published literature. Annually, an average of 15 ciguatera and 28 scombroid fish-poisoning outbreaks, involving a total of 60 and 108 ill persons, respectively, were reported to FDOSS (2000-2007). NPDS reported an average of 173 exposure calls for ciguatoxin and 200 exposure calls for scombroid fish poisoning annually (2005-2009). After adjusting for undercounting, we estimated 15,910 (90% credible interval [CrI] 4140-37,408) ciguatera fish-poisoning illnesses annually, resulting in 343 (90% CrI 69-851) hospitalizations and three deaths (90% CrI 1-7). We estimated 35,142 (90% CrI: 10,496-78,128) scombroid fish-poisoning illnesses, resulting in 162 (90% CrI 0-558) hospitalizations and 0 deaths. Ciguatera and scombroid fish poisonings affect more Americans than reported in surveillance systems. Although additional data can improve these assessments, the estimated number of illnesses caused by seafood intoxication illuminates this public health problem. Efforts, including education, can reduce

2004-10-01

Full Text Available Abstract Background Accidental poisoning is one of the leading causes of injury in the United States, second only to motor vehicle accidents. According to the Centers for Disease Control and Prevention, the rates of accidental poisoning mortality have been increasing in the past fourteen years nationally. In Texas, mortality rates from accidental poisoning have mirrored national trends, increasing linearly from 1981 to 2001. The purpose of this study was to determine if there are spatiotemporal clusters of accidental poisoning mortality among Texas counties, and if so, whether there are variations in clustering and risk according to gender and race/ethnicity. The Spatial Scan Statistic in combination with GIS software was used to identify potential clusters between 1980 and 2001 among Texas counties, and Poisson regression was used to evaluate risk differences. Results Several significant (p Conclusion The findings of the present study provide evidence for the existence of accidental poisoning mortality clusters in Texas, demonstrate the persistence of these clusters into the present decade, and show the spatiotemporal variations in risk and clustering of accidental poisoning deaths by gender and race/ethnicity. By quantifying disparities in accidental poisoning mortality by place, time and person, this study demonstrates the utility of the spatial scan statistic combined with GIS and regression methods in identifying priority areas for public health planning and resource allocation.

Objective: To investigate the causes of peripheral vascular thrombosis in patients with paraquat poisoning. Methods: The patients with paraquat poisoning who were admitted to our department in recent two years were observed to screen out the patients with large vessel thrombosis. The data on toxic exposure history, clinical features, and treatment were collected to analyze the causes of thrombosis in the patients with paraquat poisoning. Results: Three patients had typical lower limb thrombosis. There was one case of right common femoral vein thrombosis, one case of bilateral calf muscle vein thrombosis, and one case of right calf superficial vein thrombosis and right calf muscle vein thrombosis. Conclusions: After paraquat poisoning, the blood is in a hypercoagulable state and prolonged bed rest may increase the risk of thrombosis.

The Current State of Poison Control Centers in Pakistan and the Need for Capacity Building

Full Text Available Background: Chemical exposure is a major health problem globally. Poison control centers (PCCs play a leading role both in developed and developing countries in the prevention and control of poisonous chemical exposures. In this study, we aimed to assess the current state of PCCs in Pakistan and highlight capacity building needs in these centers. Methods: A cross-sectional survey of the two registered PCCs was done during August – December 2011. Necessary services of the PCCs were evaluated and the data were recorded on a predesigned checklist. Results: Both PCCs are affiliated to a tertiary care hospital. Clinical services to poisoned patients were available 24 hours a day / 7 days a week. Information on common local products was available to poison center staff. Both centers were involved in undergraduate and post graduate teaching. Telephone poison information service was not available in either of centers. There was a limited capacity for qualitative and analytical toxicology. Common antidotes were available. There were limited surveillance activities to capture toxic risks existing in the community and also a deficiency was observed in chemical disaster planning. Conclusion: PCCs in Pakistan need capacity building for specialized training in toxicology, toxicovigilance, chemical disaster planning, analytical laboratory tests and telephone service for consultation in poisoning cases.   How to cite this article: Khan NU, Mir MU, Khan UR, Khan AR, Ara J, Raja K, et al.

Toxic Mixtures in Time-The Sequence Makes the Poison.

Science.gov (United States)

Ashauer, Roman; O'Connor, Isabel; Escher, Beate I

"The dose makes the poison". This principle assumes that once a chemical is cleared out of the organism (toxicokinetic recovery), it no longer has any effect. However, it overlooks the other process of re-establishing homeostasis, toxicodynamic recovery, which can be fast or slow depending on the chemical. Therefore, when organisms are exposed to two toxicants in sequence, the toxicity can differ if their order is reversed. We test this hypothesis with the freshwater crustacean Gammarus pulex and four toxicants that act on different targets (diazinon, propiconazole, 4,6-dinitro-o-cresol, 4-nitrobenzyl chloride). We found clearly different toxicity when the exposure order of two toxicants was reversed, while maintaining the same dose. Slow toxicodynamic recovery caused carry-over toxicity in subsequent exposures, thereby resulting in a sequence effect-but only when toxicodynamic recovery was slow relative to the interval between exposures. This suggests that carry-over toxicity is a useful proxy for organism fitness and that risk assessment methods should be revised as they currently could underestimate risk. We provide the first evidence that carry-over toxicity occurs among chemicals acting on different targets and when exposure is several days apart. It is therefore not only the dose that makes the poison but also the exposure sequence.

Pharmaceutical drug poisonings, especially those that are intentional, are a serious problem for adolescents and young adults. Poison control center data is a viable tool to track intentional drug poisonings in near real-time. To determine intentional drug poisoning rates among adolescents and young adults in Ohio using poison control center data. We analyzed data from 2002 to 2014 obtained by Ohio's three poison control centers. Inclusion variables were calls made to the centers that had appropriate subject age (10-29 years old), subject sex, involved substance (all drug classes), and medical outcome (no effect, minor effect, moderate effect, major effect, and death). Intentional drug poisoning reports were also separated into subgroups to compare suspected suicide reports to misuse and abuse reports. Finally, resident population estimates were used to generate 2014 intentional drug poisoning rates for each county in Ohio. The most common age group for intentional drug poisonings was 18-24. Females reported more suspected suicide drug poisonings while males reported more misuse/abuse drug poisonings. The most reported drug class across all ages was analgesics. Of the 88 counties in Ohio, Hamilton, Williams, Washington, and Guernsey counties had the highest rates of intentional drug poisonings. The high report rate of suspected suicides and analgesic class drugs demonstrates the need for preventative measures for adolescents and young adults in Ohio. Any interventions, along with legislative changes, will need to take place in our local communities.

CANDU reactors have been analyzed and evaluated for the postulated in-core LOCA while the reactor is operating normally with low moderator poison concentration. However, when the reactor is operating with relatively large amounts of boron and/or gadolinium poisons in the moderator, the assessment for fuel integrity was required for pressure tube rupture (PTR) accident. The methodology of in-core LOCA analysis with poisoned moderator is developed to determine the effective trip parameters, evaluate the fuel integrity, and establish the standard reactor start-up model for CANDU reactor recently. The developed methodology and results are presented

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.

Successful public health media campaigns promote messages, increase awareness, engage the public, and encourage behavior change. Between 2004 and 2006, the Lead Poisoning Prevention Program of the New York City Department of Health and Mental Hygiene conducted a media campaign grounded in social learning theory and the social marketing model to increase parents' awareness of childhood lead poisoning, ways to protect their children, and property owners' legal responsibility to fix peeling lead paint safely, and increase awareness of regulatory changes and encourage enforcement of New York City's Local Law 1 of 2004. Campaign materials were focus group tested and the campaign was refined annually. The campaign ran city-wide and in targeted high-risk neighborhoods. Neighborhoods and media venue (bus, train, kiosk, and store) changed annually, based on population risk factors and venue availability. Exposure to the campaign, campaign-related knowledge, and behavior were assessed using pre- and postcampaign street intercept surveys. Results showed that campaign reached the targeted population, and had an impact on knowledge of lead poisoning prevention measures as evidenced by increased knowledge of lead paint exposures sources in one year and increased knowledge of preventive behaviors in another year; these improvements were observed for both genders and most ethnic, primary language, educational attainment, and age groups in each year. Lessons learned indicate that well-targeted media campaigns, designed with audience participation, can reach parents through various venues, and improve key knowledge areas. Evaluation challenges faced include high levels of knowledge at baseline, competing media messages, and balancing between program needs and evaluation design. © 2015 Society for Public Health Education.

Deliberate self-poisoning is a serious problem in Morocco, including in the Souss-Massa-Drâa region. However, our understanding of the problem of suicidal poisoning remains limited. This paper aims to describe the characteristics of patients, toxic substances and poisoning and to identify the risk factors influencing patient outcomes. A retrospective study was conducted of all cases of deliberate self-poisoning recorded between 1981 and 2007 by the Centre Anti-Poison et de Pharmacovigilance du Maroc. 1,130 cases of self-poisoning were identified. The mean age was 25 ± 10.1 years and the sex ratio was 0.4. Paraphenylenediamine was the most common cause of death (48 deaths), followed by hydrochloric acid (15 deaths). A close relationship was found between progression to healing and female adolescents and between progression to death and men in other age groups. The study also found that patients who used paraphenylenediamine were twelve times more likely to die (CI95%: 7.4%-19.2%) than those who used other substances. Patients with respiratory and cardiovascular conditions had a relative risk of 9.8 (CI95%: 6.3%-16%) and 3.6 (CI95%: 2.3%-5.7%). Of the 937 cases with known outcome, 89 died (9.5%).

Objective: To investigate the CT features of pulmonary injury in paraquat poisoning. Methods: The chest CT image of lung injury in 6 cases of paraquat poisoning were analyzed retrospectively. According to different period of poisoning, the 6 cases were divided into 3 types:the early stage of poisoning (within 2 d), the middle stage of poisoning (3-14 d), the late stage of poisoning (>14 d). A comparison between CT signs and the pathological features of patients was made. Results: Among this 6 cases, 3 cases died, 2 cases pulmonary fibrosis was noted, 1 cases recovered. According to different period of poisoning, the 6 cases were divided into 3 stages: in the early stage of poisoning (within 2 d), 3 cases of all patients showed nothing remarkable, 2 cases showed ground-glass opacity, 1 case showed fuzzy lung-marking.In the middle stage of poisoning (3-14 d), all 6 cases showed ground-glass opacity, mosaic attenuation; 6 cases showed pulmonary consolidation; 4 cases showed subpleural lines; 4 cases showed bronchiectasis; 2 cases showed mid-lower pleural effusion. In the late stage of poisoning (>14 d), 4 cases showed pulmonary consolidation and pulmonary fibrosis, 3 cases showed ground-glass opacity and mosaic attenuation, 1 case showed mid-lower pleural effusion; 1 case showed mediastinal emphysema. Conclusion: The clinical pathology process of paraquat poisoning was in line with CT finding which was related with clinical stage and was helpful for clinical assessment of paraquat poisoning promptly and to guide the clinical treatment.

Environmental risk assessment of white phosphorus from the use of munitions - a probabilistic approach.

White phosphorus (P(4)) is a highly toxic compound used in various pyrotechnic products. Ammunitions containing P(4) are widely used in military training areas where the unburned products of P(4) contaminate soil and local ponds. Traditional risk assessment methods presuppose a homogeneous spatial distribution of pollutants. The distribution of P(4) in military training areas is heterogeneous, which reduces the probability of potential receptors being exposed to the P(4) by ingestion, for example. The current approach to assess the environmental risk from the use of P(4) suggests a Bayesian network (Bn) as a risk assessment tool. The probabilistic reasoning supported by a Bn allows us to take into account the heterogeneous distribution of P(4). Furthermore, one can combine empirical data and expert knowledge, which allows the inclusion of all kinds of data that are relevant to the problem. The current work includes an example of the use of the Bn as a risk assessment tool where the risk for P(4) poisoning in humans and grazing animals at a military shooting range in Northern Norway was calculated. P(4) was detected in several craters on the range at concentrations up to 5.7g/kg. The risk to human health was considered acceptable under the current land use. The risk for grazing animals such as sheep, however, was higher, suggesting that precautionary measures may be advisable.

The Israel National Poison Information Center (IPIC), Rambam Health Care Campus, provides 24 hour telephone consultations in clinical toxicology as well as drug and teratogen information. It participates in research, teaching and regulatory activities, and also provides laboratory services. To report data on the epidemiology of poisonings and poison exposures in Israel. We made computerized queries and descriptive analyses of the medical records database of the IPIC during 2012. A total of 31,519 poison exposure cases were recorded, a 157.6% increase compared with 1995. Children snake venom. Four fatalities were recorded; all were intentional exposures in adults (corrosive, medications, energy drink). Poison exposures and poisonings have increased significantly and have contributed substantially to morbidity and mortality in Israel. The IPIC database is a valuable national resource for the collection and monitoring of poisoning exposure cases. It can be used as a real-time surveillance system for the benefit of public health. It is recommended that reporting to the IPIC become mandatory and its activities be adequately supported by national resources.

Intentional and unintentional poisoning are among the most common reasons for referrals to emergency department (ED). Therefore, the present study was designed to evaluate epidemiologic features and effective risk factors of intentional and unintentional poisoning in children. This prospective cross-sectional study was carried out in ED of Loghman Hakim Hospital, greatest referral poison center of Iran, Tehran during March to August 2014. Demographic data, medical history, history of psychiatric disease in child, the cause of poisoning, parents' educational level, household monthly income, location of residence, history of addiction or divorce in family, and the poisoning intentionality were gathered. Data were analyzed using SPSS 18 and appropriate statistical tests based on the purpose of study. 414 participants with the mean age of 4.2 ± 3.43 years were included (57.5% male). Children in the 0-4 year(s) age range had the most frequency with 281 (67.9%) cases. 29 (7%) cases were intentional (62% female, 76% in the 10-14 years old group). Methadone with 123 (29.7%) cases was the most frequent toxic agent in general and in unintentional cases. 10-14 years of age (p = 0.001), and the history of psychiatric disease in children (p <0.001), had a direct correlation with probability of intentional poisoning. While, history of addiction in the family showed an indirect correlation with this probability (p = 0.045). Based on the results of this study, most cases of poisoning in the children were unintentional methadone intoxication in boys in the 0-4 age range with a history of a psychiatric disease, and those who had a history of addiction in the family. In addition, the most powerful risk factor for the children's intentional poisoning was their history of psychiatric disease. The history of addiction in the child's family had indirect correlation with intentional intoxications.

Management of acute organophosphorus pesticide poisoning.

Eddleston, Michael; Buckley, Nick A; Eyer, Peter; Dawson, Andrew H

2008-02-16

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.

Pakistan has one of the highest prevalence of poisoning in the world. However, limited data exist on the frequency of poisons implicated in homicidal, suicidal, and accidental cases in North-West Pakistan (Khyber Pakhtunkhwa). This retrospective study of 353 cases and biological specimens of poisoning received at the department of Forensic medicine and toxicology, Khyber Medical College Peshawar from 13 districts of Khyber Pakhtunkhwa. Frequency of poisoning was assessed by testing each specimen for 17 different poisons. Of all the specimens, 250 (70.8%) specimens tested positive and the rest didn't show any indication of poisoning (n=103, 29.2%). The most frequent poisons detected were benzodiazepines (total n=75), organophosphates (total n=58), phencyclidine (total n=30) and morphine (total n=23). Gender had a significant association with benzodiazepines (p=0.011), tricyclic antidepressants (p=0.001), and organophosphates (ppoisoning in females while benzodiazepines were the most common cause of poisoning in males. Poisoning by benzodiazepines, organophosphates and phencyclidine are the most common causes of intoxication in population of Khyber Pakhtunkhwa. Source of poisoning varies with gender for organophosphates, benzodiazepines and tricyclic antidepressants.

Variability in the management of lithium poisoning.

Roberts, Darren M; Gosselin, Sophie

2014-01-01

Three patterns of lithium poisoning are recognized: acute, acute-on-chronic, and chronic. Intravenous fluids with or without an extracorporeal treatment are the mainstay of treatment; their respective roles may differ depending on the mode of poisoning being treated. Recommendations for treatment selection are available but these are based on a small number of observational studies and their uptake by clinicians is not known. Clinician decision-making in the treatment of four cases of lithium poisoning was assessed at a recent clinical toxicology meeting using an audience response system. Variability in treatment decisions was evident in addition to discordance with published recommendations. Participants did not consistently indicate that hemodialysis was the first-line treatment, instead opting for a conservative approach, and continuous modalities were viewed favorably; this is in contrast to recommendations in some references. The development of multidisciplinary consensus guidelines may improve the management of patients with lithium poisoning but prospective randomized controlled trials are required to more clearly define the role of extracorporeal treatments. © 2014 Wiley Periodicals, Inc.

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.

Ciguatera fish poisoning (CFP) is endemic in certain tropical and subtropical regions of the world. CFP had not been described on the West Africa Coast until a 2004 outbreak in the Canary Islands. In 2008-2009, two additional outbreaks of ciguatera occurred. Individuals afflicted had consumed lesser amberjack (Seriola rivoliana) captured from nearby waters. Caribbean ciguatoxin-1 (C-CTX-1) was confirmed in fish samples by LC-MS/MS. Ciguatoxic fish in this region may pose a new health risk for the seafood consumer. Copyright © 2010 Elsevier Ltd.

Full Text Available Objectives: Poisoned patients are at risk of impaired ventilation in many situations. The purpose of this descriptive study was to investigate the impact of educational workshops on nurses' knowledge, confidence, and attitude in taking care of poisoned patients. Materials and Methods: This descriptive study was performed on 60 nursing staff in the intensive care unit (ICU for poisoned patients in Imam Reza (p hospital, Mashhad, Iran. Data was gathered by a researcher-designed questionnaire. Studied scales included perceived importance and novelty of educational meeting, matching with professional and educational needs, illustration of practical and knowledge weaknesses and strength and finally satisfaction in holding regular workshops annually. Two, half day workshops were held and various items were taught with various methods. The knowledge of participants was assessed by pretests and post-tests consisting of 12 items related to workshop topics. The impact of these educational meetings was evaluated and the results were analyzed by the SPSS software. Results: According to the results, workshops improved awareness of nurses about their weakness and strength points, professional knowledge and their interest and attention; likewise all participants had the same opinion about a strong need to hold similar workshops more than once and preferably 2 to 3 times annually. Conclusion: It seems that short educational courses in small groups for reviewing the old data and recent findings in the context of critical care are useful in order to promote the knowledge and skills of ICU staff in taking care of poisoned patients

Poison control centers and clinical toxicologists serve many roles within public health; however, the degree to which these entities collaborate is unknown. The objective of this survey was to identify successful collaborations of public health agencies with clinical toxicologists and poison control centers. Four areas including outbreak identification, syndromic surveillance, terrorism preparedness, and daily public health responsibilities amenable to poison control center resources were assessed. An online survey was sent to the directors of poison control centers, state epidemiologists, and the most senior public health official in each state and selected major metropolitan areas. This survey focused on three areas: service, structure within the local or state public health system, and remuneration. Questions regarding remuneration and poison control center location within the public health structure were asked to assess if these were critical factors of successful collaborations. Senior state and local public health officials were excluded because of a low response rate. The survey was completed in October 2007. A total of 111 respondents, 61 poison control centers and 50 state epidemiologists, were eligible for the survey. Sixty-nine (62%) of the 111 respondents, completed and returned the survey. Thirty-three (54%) of the 61 poison control centers responded, and 36 of the 50 state epidemiologists (72%) responded. The most frequent collaborations were terrorism preparedness and epidemic illness reporting. Additional collaborations also exist. Important collaborations exist outside of remuneration or poison control centers being a formal part of the public health structure. Poison control centers have expanded their efforts to include outbreak identification, syndromic surveillance, terrorism preparedness, and daily public health responsibilities amenable to poison control center resources. Collaboration in these areas and others should be expanded. Published

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.

Gastric Lavage in Acute Organophosphorus Pesticide poisoning (GLAOP – a randomised controlled trial of multiple vs. single gastric lavage in unselected acute organophosphorus pesticide poisoning

Directory of Open Access Journals (Sweden)

Cao YuPing

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

Suicide and unintentional poisoning mortality trends in the United States, 1987-2006: two unrelated phenomena?

Directory of Open Access Journals (Sweden)

Frost James L

2010-11-01

Full Text Available Abstract Background Two counter trends in injury mortality have been separately reported in the US in recent times - a declining suicide rate and a rapidly rising unintentional poisoning mortality rate. Poisoning suicides are especially difficult to detect, and injury of undetermined intent is the underlying cause-of-death category most likely to reflect this difficulty. We compare suicide and poisoning mortality trends over two decades in a preliminary assessment of their independence and implications for suicide misclassification. Methods Description of overall and gender- and age-specific trends using national mortality data from WISQARS, the Web-based Injury Statistics Query and Reporting System, maintained by the Centers for Disease Control and Prevention (CDC. Subjects were the 936,633 residents dying in the 50 states and the District of Columbia between 1987 and 2006 whose underlying cause of death was classified as suicide, unintentional poisoning, or injury mortality of undetermined intent. Results The official US suicide rate declined 18% between 1987 and 2000, from 12.71 to 10.43 deaths per 100,000 population. It then increased to 11.15 deaths per 100,000 by 2006, a 7% rise. By contrast to these much smaller rate changes for suicide, the unintentional poisoning mortality rate rose more than fourfold between 1987 and 2006, from 2.19 to 9.22 deaths per 100,000. Only the population aged 65 years and older showed a sustained decline in the suicide rate over the entire observation period. Consistently highest in gender-age comparisons, the elderly male rate declined by 35%. The elderly female rate declined by 43%. Unlike rate trends for the non-elderly, both declines appeared independent of corresponding mortality trends for unintentional poisoning and poisoning of undetermined intent. The elderly also deviated from younger counterparts by having a smaller proportion of their injury deaths of undetermined intent classified as poisoning

Kipping, Ruth; Eastcott, Howard; Sarangi, Joyshri

2006-12-01

Ciguatera toxin causes a range of gastrointestinal, cardiovascular and neurological symptoms that occur within 1-6 h of ingesting fish with the toxin and can last for days, months or years. It is a well-recognized problem in the tropics. Avon Health Protection Team investigated food poisoning on a ship at Avonmouth, which was thought by the crew to be related to a white snapper fish from the Caribbean. The symptoms were initially thought to be scombroid fish poisoning but were consistent with ciguatera fish poisoning. Cases of fish poisoning from fish imported from the Caribbean and Pacific or travellers returning from tropical countries may be ciguatera fish poisoning, but mistakenly diagnosed as scombroid fish poisoning.

Berg, Daniel R; Eckstein, Erin T; Steiner, Matt S; Gavard, Jeffrey A; Gross, Gilad A

2012-03-01

We assessed the screening and remediation of home lead hazards prenatally in a high-risk population, hypothesizing that average blood-lead level and the number of poisonings would drop by 25%. One hundred fifty-two women underwent prenatal home inspections by certified lead inspectors. The hazards that were identified were remediated. The blood-lead levels of children of participating women were compared with matched control subjects. Blood-lead levels were obtained from 60 children and compared with matched control subjects. The average blood-lead level of children in the treatment group was 2.70 μg/dL vs 3.73 μg/dL in control subjects (P = .019). The percentage of children with levels >10 μg/dL in the treatment group was 0% vs 4.2% in control subjects (P = .128). Screening and remediation of houses of pregnant women is effective to reduce the average blood-lead level and number of children that exceed the federal level of concern for lead poisoning in a high-risk population.

Glenn, Lauren

2015-01-01

Accidental childhood poisonings are a major public health concern despite many efforts to alleviate this problem. While the rate of pediatric fatalities due to poisonings have decreased over the last two decades, poison control centers around the US have collectively fielded over one million calls with regard to toxic exposures in the preschool age group. According to the American Association of Poison Control Centers nearly half of all human exposures reported last year involved children under six. By focusing poison prevention efforts on the preschooler, we can attempt to decrease morbidity and mortality in the most vulnerable age group affected. Although the subject is still prevalent, current discussion on this topic is limited. Newer literature discusses past initiatives such as child resistant packaging and sticker deterrent programs and addresses their efficacy. This article revisits older mechanisms of prevention as well as the science behind the human motivation to change one's own practice and behavior. Copyright © 2015 Elsevier Inc. All rights reserved.

There is little information on poisonings managed at military and Veterans Administration (VA) hospitals. This investigation described and compared poisonings reported to Texas poison centers that were managed at military and VA hospitals. Retrospective analysis of poison centre data. Cases were poisonings among patients aged 18 years or more reported to Texas poison centers during 2000-2015 where management occurred at a military or VA hospital. The distribution of exposures for various demographic and clinical factors was determined for military and veterans hospitals and comparisons were made between the two groups. There were 4353 and 1676 poisonings managed at military and VA hospitals, resepctively. Males accounted for 50.5% of the military hospital patients and 84.9% of the VA hospital patients. The mean age for military hospital patients was 31 years and for VA hospital patients was 50 years. The proportion of poisonings managed at military hospitals and VA hospitals, respectively, were intentional (70.0% vs 64.1%), particularly suspected attempted suicide (57.3% vs 47.7%), and unintentional (25.0% vs 30.5%). More than one substance was reported in 37.7% of military and 33.2% of VA hospital poisonings. The most commonly reported substance categories for poisonings managed at military and VA hospitals, respectively, were analgesics (28.4% vs 19.7%), sedatives/hypnotics/antipsychotics (24.7% vs 23.4%), antidepressants (18.7% vs 19.7%) and alcohol (11.3% vs 10.6%). A number of differences were observed between poisonings managed at military and VA hospitals. These differing patterns of poisonings may need to be taken into account in the education, prevention and treatment of poisonings at these hospitals and among the populations they serve.

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

[Plant poisoning cases in Turkey].

Oztekin-Mat, A

1994-01-01

In Turkey, the majority of the population live in rural areas where they use wild plants as food and medicine. The confusion of an edible plant with a poisonous one give rise to serious poisoning which may even result in death. The incidence of plant poisoning in Turkey is about 6% and especially high among children between ages of 2 and 11 living in rural areas. The number of species that cause poisoning is around twenty and Hyoscyamus niger (Solanaceae), Colchicum species (Liliaceae), Conium maculatum (Umbelliferae) and Prunus species (Rosaceae) are the most important. Mushroom poisoning is more frequent in spring and fall. The main reasons are their widespread usage as food and the inexperience of the gatherers in distinguishing the edibles from the poisonous. Amanita phalloides, A. verna, A. muscaria, A. pantherina are responsible for severe cases of poisoning.

Full Text Available Introduction: Intentional and unintentional poisoning are among the most common reasons for referrals to emergency department (ED. Therefore, the present study was designed to evaluate epidemiologic features and effective risk factors of intentional and unintentional poisoning in children. Methods: This prospective cross-sectional study was carried out in ED of Loghman Hakim Hospital, greatest referral poison center of Iran, Tehran during March to August 2014. Demographic data, medical history, history of psychiatric disease in child, the cause of poisoning, parents’ educational level, household monthly income, location of residence, history of addiction or divorce in family, and the poisoning intentionality were gathered. Data were analyzed using SPSS 18 and appropriate statistical tests based on the purpose of study. Results: 414 participants with the mean age of 4.2 ± 3.43 years were included (57.5% male. Children in the 0-4 year(s age range had the most frequency with 281 (67.9% cases. 29 (7% cases were intentional (62% female, 76% in the 10-14 years old group. Methadone with 123 (29.7% cases was the most frequent toxic agent in general and in unintentional cases. 10-14 years of age (p = 0.001, and the history of psychiatric disease in children (p <0.001, had a direct correlation with probability of intentional poisoning. While, history of addiction in the family showed an indirect correlation with this probability (p = 0.045. Conclusion: Based on the results of this study, most cases of poisoning in the children were unintentional methadone intoxication in boys in the 0-4 age range with a history of a psychiatric disease, and those who had a history of addiction in the family. In addition, the most powerful risk factor for the children’s intentional poisoning was their history of psychiatric disease. The history of addiction in the child’s family had indirect correlation with intentional intoxications.

Determinants of U.S. poison center utilization.

Science.gov (United States)

Litovitz, Toby; Benson, Blaine E; Youniss, Jessica; Metz, Edward

2010-06-01

High poison center utilization has been associated with decreased emergency department usage and hospitalization rates. However, utilization requires awareness of the poison center. Penetrance, defined as the number of human poison exposures reported to a poison center per 1,000 population, has been used as a marker of poison center awareness. To identify factors that influence poison center penetrance to optimize the life- and cost-saving benefits of poison control centers. Human poison exposures that were reported to the National Poison Data System in 2001 were analyzed to identify and rank factors affecting poison center penetrance. Overall penetrance correlated with pediatric penetrance (R(2) = 0.75, p poison center that were already in or en route to a healthcare facility at the time of the call to the poison center (R(2) = 0.41, p poison center service populations were associated with lower penetrance (R(2) = 0.23, p poison center (multiple regression). Positive predictors included the percentage of the population younger than 5 years, the percentage of the adult population with a bachelor's degree, poison center certification, poison center educator FTEs (full time equivalents), Asian population percentage, and population density. The inverse correlation between pediatric penetrance and healthcare facility utilization supports prior observations of excessive healthcare utilization when a poison center is not called. Since race, language and distance are barriers to poison center utilization, and since healthcare utilization increases when poison center penetrance declines, low penetrance suggests a lack of awareness of the poison center rather than a low incidence of poisonings. Strategies to raise penetrance should be informed by an understanding of the barriers to utilization - language, Black/African American race, distance from the poison center, poverty, and lower education levels.

Guidotti, Tee

2006-01-01

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.

Gastric lavage in patients with acute poisoning

Directory of Open Access Journals (Sweden)

Montserrat Amigó Tadín

2012-05-01

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.

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.

1983-01-01

Purpose: To rapidly control the chain reaction due to thermal neutrons in a reactor core by using gaseous poisons as back-up means for control rod drives. Constitution: Gaseous poisons having a large neutron absorption cross section are used as back-up means for control rod drives. Upon failure of control rod insertion, the gaseous poisons are injected into the lower portion of the reactor core to control the reactor power. As the gaseous poisons, vapors at a high temperature and a higher pressure than that of the coolants in the reactor core are injected to control the reactor power due to the void effects. Since the gaseous poisons thus employed rapidly reach the reactor core and form gas bubbles therein, the deccelerating effect of the thermal neutrons is decreased to reduce the chain reaction.

2009-01-01

Full Text Available Chelation therapy has been the major treatment for heavy metal poisoning. Various chelating agents have been developed and tested for treatment of heavy metal intoxications, including mercury poisoning. It has been clearly shown that chelating agents could rescue the toxicity caused by heavy metal intoxication, but the potential preventive role of chelating agents against heavy metal poisoning has not been explored much. Recent paper by Siddiqi and colleagues has suggested a protective role of chelating agents against mercury poisoning, which provides a promising research direction for broader application of chelation therapy in prevention and treatment of mercury poisoning.

The herbicide paraquat is associated with a high mortality rate. It produces multiorgan damage through the induction of acute oxidative stress, by generation of reactive oxygen species that cause oxidative damage to biomolecules. In addition to general supportive measures, the management of paraquat poisoning includes gastric washing, forced diuresis, haemodialysis and the use of antioxidants, such as N-acetylcysteine. However, this drug is rather unavailable in Venezuela and S-carboxymethylcysteine has been used. We report 35 patients with mild to severe paraquat poisoning, which beside standard supportive treatment received 1500 mg S-carboxymethylcysteine, up to 2-3 w. The mortality rate was 22.86% (8 deaths/35 cases) and was related to the severity of paraquat poisoning (as assessed by urine dithionite tests). We conclude that S-carboxymethylcysteine is a reliable alternative in managing patients with paraquat poisoning.

In May 2010, a team of national and international organizations was assembled to investigate children's deaths due to lead poisoning in villages in northwestern Nigeria. Our goal was to determine the cause of the childhood lead poisoning outbreak, investigate risk factors for child mortality, and identify children data. Multivariate logistic regression techniques were used to determine risk factors for childhood mortality. We surveyed 119 family compounds. Of 463 children 45 µg/dL), and incidence of convulsions among children before death (82%) suggest that most of the recent childhood deaths in the two surveyed villages were caused by acute lead poisoning from gold ore-processing activities. Control measures included environmental remediation, chelation therapy, public health education, and control of mining activities.

Over 2 million human exposure calls are reported annually to United States regional poison information centers. All exposures are documented electronically and submitted to the American Association of Poison Control Center's National Poison Data System. This database represents the largest data source available on the epidemiology of pharmaceutical and non-pharmaceutical poisoning exposures. The accuracy of these data is critical; however, research has demonstrated that inconsistencies and inaccuracies exist. This study outlines the methods and results of a training program that was developed and implemented to enhance the quality of data collection using acetaminophen exposures as a model. Eleven poison centers were assigned randomly to receive either passive or interactive education to improve medical record documentation. A task force provided recommendations on educational and training strategies and the development of a quality-measurement scorecard to serve as a data collection tool to assess poison center data quality. Poison centers were recruited to participate in the study. Clinical researchers scored the documentation of each exposure record for accuracy. Results. Two thousand two hundred cases were reviewed and assessed for accuracy of data collection. After training, the overall mean quality scores were higher for both the passive (95.3%; + 1.6% change) and interactive intervention groups (95.3%; + 0.9% change). Data collection accuracy improved modestly for the overall accuracy score and significantly for the substance identification component. There was little difference in accuracy measures between the different training methods. Despite the diversity of poison centers, data accuracy, specifically substance identification data fields, can be improved by developing a standardized, systematic, targeted, and mandatory training process. This process should be considered for training on other important topics, thus enhancing the value of these data in

Burnable poison rod

International Nuclear Information System (INIS)

Natsume, Tomohiro.

1988-01-01

Purpose: To increase the reactor core lifetime by decreasing the effect of neutron absorption of burnable poison rods by using material with less neutron absorbing effect. Constitution: Stainless steels used so far as the coating material for burnable poison rods have relatively great absorption in the thermal neutral region and are not preferred in view of the neutron economy. Burnable poison rods having fuel can made of zirconium alloy shows absorption the thermal neutron region lower by one digit than that of stainless steels but they shows absorption in the resonance region and the cost is higher. In view of the above, the fuel can of the burnable poison material is made of aluminum or aluminu alloy. This can reduce the neutron absorbing effect by stainless steel fuel can and effectively utilize neutrons that have been wastefully absorbed and consumed in stainless steels. (Takahashi, M.)

Potential use of hyperoxygenated solution as a treatment strategy for carbon monoxide poisoning.

Directory of Open Access Journals (Sweden)

Xingxing Sun

Full Text Available AIM: Carbon monoxide (CO poisoning can cause permanent damage in tissues that are sensitive to hypoxia. We explored the feasibility and efficacy of using a hyperoxygenated solution (HOS to treat severe acute CO poisoning in an animal model. METHODS: Male Sprague-Dawley rats were subjected to CO poisoning. The HOS was administered into the femoral vein of these rats through a catheter (10 ml/kg. Carboxyhemoglobin (COHb and blood gases were used to assess the early damage caused by CO poisoning. S100β was measured to predict the development of late cognitive sequelae of CO. The Morris water maze test was performed to assess cognitive function, and Nissl staining was performed to observe histologic change. RESULTS: The COHb concentrations rapidly decreased at 5 min after the HOS administration; however, the PaO2 and SaO2 in rats treated with HOS increased significantly 5 min after the HOS administration. The S100β concentrations, which increased significantly after CO poisoning, increased at a much slower rate in the rats treated with HOS (HOS group compared with the rats treated with O2 inhalation (O2 group. The escape latency in the place navigation test was shortened after CO poisoning on days 11-15 and days 26-30, and the swimming time in quadrant 4 in the spatial probe test on days 15 and 30 after CO poisoning was prolonged in the rats treated with HOS injection compared with the rats treated with oxygen inhalation or normal saline injection. The neuronal degeneration in the HOS group was alleviated than that in the CO or O2 group. CONCLUSION: HOS efficiently alleviates the brain damage in acute CO-poisoned rats and thus may serve as a new way to treat human patients with CO poisoning in clinical practice.

Social referencing "Mr. Yuk": the use of emotion in a poison prevention program.

Science.gov (United States)

Pooley, Amanda J; Fiddick, Laurence

2010-05-01

To assess whether disgust, the emotion depicted on poison control "Mr. Yuk" stickers, conveys an age-appropriate message to young children. Two preliminary studies (both N = 48) were conducted with adults to assess what facial expressions of emotion they associated with child and adult violations of precautionary rules. Subsequently, 20 3-year-olds and 35 4-year-olds were tested on age-appropriate scenarios to determine what facial expressions of emotion they associate with accidental poisonings. Adults associated violations of precautionary rules, regardless of whether they involved children or adults and physical injury or accidental poisonings, with facial expressions of fear, not disgust. The study conducted with children indicated that they likewise anticipated facial expressions of fear in response to accidental poisonings. The disgust displayed on Mr. Yuk stickers does not appear to convey a valid emotional message, regardless of whether the stickers are used for preventive or educational purposes.

Long term mortality study of chromate pigment workers who suffered lead poisoning

Energy Technology Data Exchange (ETDEWEB)

Davies, J.M.

1984-05-01

Long term mortality was studied in a group of 57 chromate pigment workers who suffered clinical lead poisoning, mostly between 1930 and 1945. One death was attributed to lead poisoning and there were significant excesses of deaths from nephritis (observed/expected 3/0.24) and cerebrovascular disease (9/2.20), as well as non-significant excesses for respiratory diseases (7/3.59) and accidents and violence (3/1.13). The deaths from nephritis followed long spells of service exceeding 10 years. Poisoning appeared to have more adverse long term effects on older workers: 15 men aged 40 or over at the time of acute poisoning experienced generally high mortality, and 30 years later or by the end of 1981 only two survived instead of the seven expected. The risk of cerebrovascular disease appeared to be unrelated to duration of exposure and affected even men employed for under one year. Excluding the 57 lead poisoned men, other contemporary workers at the factories showed no excess mortality from cerebrovascular disease.

French law as regards renunciation to mining concessions calls for the mining operator to first undertake analyses of the risks represented by their underground mining works. The problem of gas migration to the surface is especially significant in the context of coal mines. This is because mine gas can migrate to the earth's surface, then present significant risks: explosion, suffocation or gas poisoning risks. As part of the scheduled closure of all coal mining operations in France, INERIS has drawn up, at the request of national mining operator Charbonnages de France, a general methodology for assessing the risk linked to gas in the context of closed coal mines. This article presents the principles of this methodology. An application example based on a true case study is then described. This is completed by a presentation of the preventive and monitoring resources recommended and usually applied in order to manage the risk linked to gaseous emissions. (authors)

Dog poisoning with furadan 35-ST (carbamate insecticide

Directory of Open Access Journals (Sweden)

Aleksić Jelena

2011-01-01

Full Text Available The first case of poisoning of a dog with Furadan 35-ST in Serbia is described. The active ingredient of Furadan 35-ST is carbofuran (2,3-dihydro-2,2-dimethyl-7- benzofuranyl methyl carbamate, a carbamate insecticide, acaricide and nematocide. This highly poisonous substance is classified by the World Health Organisation into Class 1 b and in Serbia into Group 1 of The List of Poisons. Pathological assessment revealed hyperaemia and degenerative and necrotic changes in the liver, kidneys and heart. In addition, lysis of the nuclei in the motor neurons, loss of tigroid substance and pericellular oedema in the ventral horns of the spinal cord, and acute pancreatitis were found. In addition to the non-specific changes (hyperaemia, degenerative and necrotic changes in the parenchymal organs, the ones in the ventral horns of the spinal cord and acute pancreatitis may lead to carbamate poisoning being suspected. The diagnosis was established on the grounds of toxicological-chemical conformation of carbofuran by means of GC-MS in addition to the macroscopic, microscopic findings in tissue samples taken from the stomach and the liver, which confirmed the suspicion of the dog having been poisoned with the carbamate insecticide. In the current case the results of the diagnostic procedures provided foundations for the initiation of criminal proceedings.

Black ducks and mallards were found to be highly susceptible to phosphorus poisoning. 3 mg. of white phosphorus per kg. of body weight given in a single dose resulted in death of a black duck in 6 hours. Pathologic changes in both acute and chronic poisoning were studied. Data are presented showing that diagnosis can be made accurately by chemical analysis of stored tissues in cases of phosphorus poisoning.

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.

Copper sulphate poisoning in horses

Energy Technology Data Exchange (ETDEWEB)

Bauer, M

1975-01-01

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.

What is the definition of a poisoning?

Science.gov (United States)

Uges, D R

2001-03-01

New insights in medicine and acceptable treatments necessitates an adjustment of the existing definition of clinical or forensic poisoning to: 'An individual's medical or social unacceptable condition as a consequence of being under influence of an exogenous substance in a dose too high for the person concerned'. For medical and legal purposes it is important to know how the victim became poisoned. In general, there are three ways of causing medical poisoning: accidental poisoning, including iatrogenic poisoning, experimental and intentional poisoning. Nowadays iatrogenic intoxication, poisoning caused by the Münchhausen's syndrome (by proxy) and experimental poisoning (designer drugs) have a major place in contemporary toxicology. Although some toxicologists use the word 'intoxication' only overdoses with central effects, in this article 'intoxication' and 'poisoning' are considered to be synonymous.

To determine the prevalence of lead (Pb) poisoning at birth in Morelos, analyze its distribution by social marginalization level, and estimate the association with the use of lead glazed ceramics (LGC). Blood lead level (BLL) in umbilical cord was measured in a representative sample of 300 randomly selected births at the Morelos Health Services and state IMSS. The prevalence of Pb poisoning at birth (BLL> 5μg/dL) was 14.7% (95%CI: 11.1, 19.3) and 22.2% (95%CI: 14.4, 32.5) in the most socially marginalized municipalities. 57.1% (95%CI: 51.3, 62.7) of the mothers used LGC during pregnancy, and the frequency of use was significantly associated with BLL. This is the first study to document the proportion of newborns with Pb poisoning who are at risk of experiencing the related adverse effects. It is recommended to monitor BLL at birth and take action to reduce this exposure, especially in socially marginalized populations.

A Rare but Potentially Fatal Poisoning; Aluminum Phosphide Poisoning

Directory of Open Access Journals (Sweden)

Orkun Tolunay

2017-04-01

Full Text Available Phosphide, a very toxic gas, is used in our country as aluminium phosphide tablets impregnated in clay. It is widely used since it has a very high diffusion capacity, whereby it can eradicate all living creatures in any form of their life cycle and does not leave any remnants in agricultural products. Aluminum phosphide poisoning is among intoxications for which there are still no true antidotes. Mortality rate varies between 30% and 100%. This paper presents a case of aluminum phosphide poisoning caused by the uncompleted suicide attempt. A 14-year-old girl, who swallowed aluminum phosphate tablets, was brought to the emergency department with the complaints of nausea and vomiting. The patient was treated with gastric lavage and activated charcoal. Since the patient ingested a lethal amount of aluminum phosphide, she was referred to the pediatric intensive care unit. The patient was discharged in stable condition after supportive care and monitoring. Specific antidotes are life-saving in poisonings. However, this case was presented to show how general treatment principles and quick access to health services affect the result of treatment. Also, we aimed to highlight the uncontrolled selling of aluminum phosphate, which results in high mortality rates in case of poisoning.

Calculated risks

International Nuclear Information System (INIS)

Rodricks, J.V.

1992-01-01

This book is a clear, practical, and balanced view of toxicology and risk management. The introduction argues the case for risks assessment and outlines the benefits and problems associated with chemical exposure. The first part of the book covers the basic science and the sources of human exposure to chemicals. Absorption, distribution, metabolism, and excretion are covered in some detail. The subsequent chapter gives a lively discussion of toxicity studies and then describes slow and fast poisons. The author gives the arguments for as well as against animal testing. There is much public bewilderment caused by reports of cancer-causing pesticides in apple juice and poisons emanating from nearby hazardous waste sites. The author believes that too much has been written in an attempt to expose governmental and corporate ignorance, negligence, and corruption. This book is less of a polemic, and more of a clear, unbiased clarification of the scientific basis for our concerns and uncertainties. It should serve to refocus the debate

Waterpipe smoking may increasingly account for unintentional carbon monoxide poisoning, a serious health hazard with high morbidity and mortality. We aimed at identifying waterpipe smoking as a cause for carbon monoxide poisoning in a large critical care database of a specialty care referral center. This retrospective cohort study included patients with a history of exposure to waterpipe smoking and carbon monoxide blood gas levels >10% or presence of clinical symptoms compatible with CO poisoning admitted between January 2013 and December 2016. Patients' initial symptoms and carbon monoxide blood levels were retrieved from records and neurologic status was assessed before and after hyperbaric oxygen treatment. Sixty-one subjects with carbon monoxide poisoning were included [41 males, 20 females; mean age 23 (SD ± 6) years; range 13-45] with an initial mean carboxyhemoglobin of 26.93% (SD ± 9.72). Most common symptoms included syncope, dizziness, headache, and nausea; 75% had temporary syncope. Symptoms were not closely associated with blood COHb levels. CO poisoning after waterpipe smoking may present in young adults with a wide variability of symptoms from none to unconsciousness. Therefore diagnosis should be suspected even in the absence of symptoms.

2010-11-01

A rational medical, occupational and toxicological approach is instrumental to select objectively among pregnant women exposed to chemicals at the workplace those who should be withdrawn or benefit from improvements of working conditions. Risk assessment is based on a comprehensive review of compounds' hazards and a thorough evaluation of the actual exposure including biomonitoring whenever as possible. Since 1996, the Lyon Poison Center has been conducting a prospective follow-up of pregnant women exposed to chemicals at the workplace. Of these, 206 exposed to organic solvents since conception were selected and matched with 206 exposed to a non-embryotoxic agent. Total withdrawal from the workplace was recommended in 22% of cases, but exposure was not considered to be hazardous to pregnancy in 51%. Overall, no increase in adverse outcomes was found. Maintaining pregnant women at their workplace, particularly most of the laboratory technicians, is reasonably possible after careful toxicological risk assessment. Copyright © 2010 Elsevier Inc.

Kaufmann, R.B.; Staes, Catherine J.; Matte, Thomas D.

2003-01-01

This study was conducted to describe trends in US lead poisoning-relate deaths between 1979 and 1998. The predictive value of relevant ICD-9 codes was also evaluated. Multiple cause-of-death files were searched for record containing relevant ICD-9 codes, and underlying causes and demographic characteristics were assessed. For 1979-1988, death certificates were reviewed; lead source information was abstracted and accuracy of coding was determined. An estimated 200 lead poisoning-related deaths occurred from 1979 to 1998. Most were among males (74%), Blacks (67%), adults of age ≥45 years (76%), and Southerners (70%). The death rate was significantly lower in more recent years. An alcohol-related code was a contributing cause for 28% of adults. Only three of nine ICD-9 codes for lead poisoning were highl predictive of lead poisoning-related deaths. In conclusion, lead poisoning-related death rates have dropped dramatically since earlier decades and are continuing to decline. However, the findings imply that moonshine ingestion remains a source of high-dose lead exposure in adults

CIGUATERA POISONING: PACIFIC DISEASE, FOODBORNE POISONING FROM FISH IN WARM SEAS AND OCEANS. Review

Full Text Available Purpose: The review is provoked because of lack of awareness of the medical practitioners in Bulgaria concerning of the ethnology, pathogenesis, clinical symptoms and treatment of the ciguatera fish poisoning (CFP. This can be a source of prolonged diagnostic delays, as some cases reporting in another country in Europe, for example Germany, Spain and UK. Varna is the sea town with many sailor crews returning from tropical and subtropical regions, or CFP can affect people who travel to the Pacific and Caribbean or ate exotic fish from supermarket. The information of this fish food-borne poisoning is part of student’s education in discipline “Marine medicine” in Medical University, Varna. Materials and methods: To present better information from different authors and last scientific data, we made review of published materials of 58 issues to construct definition, history, etiology, pathogenesis (toxins and mechanisms of action, clinical symptoms, treatment and prevention of the Ciguatera or ichtyosarcotoxicosis, a wide spread food-born poisoning. Results: Ciguatera poisoning is ichtyosarcotoxicosis, a wide-spread foodborne poisoning in people after consumption of flesh of different kinds of fishes in which toxins produced by poisonous microorganisms (Dinoflagellates have accumulated. The poisoning develops by accumulating toxins higher up the food chain starting with toxin producing dinoflagellates (species: Gambierdiscus toxicus, Prorocentrum concavum, Pr. lima, Ostreoposis lenticularis, Ostr. Siamensis and others, continuing with the poisoned algae (species: Portieria, Halymenia, Turbinaria, Sargassum, and after that involving small crustacea and small fishes to greater fishes (vector fishes, genus Herbivores and Carnivores, in which the toxins have been stored in amount, great enough to cause foodborne poisoning in humans. This poisoning is widespread in tropical and subtropical regions, but because of its delayed toxic effects, lasting

Venomous and Poisonous Australian Animals of Veterinary Importance: A Rich Source of Novel Therapeutics

Science.gov (United States)

Allavena, Rachel E.

2014-01-01

Envenomation and poisoning by terrestrial animals (both vertebrate and invertebrate) are a significant economic problem and health risk for domestic animals in Australia. Australian snakes are some of the most venomous animals in the world and bees, wasps, ants, paralysis ticks, and cane toads are also present as part of the venomous and poisonous fauna. The diagnosis and treatment of envenomation or poisoning in animals is a challenge and can be a traumatic and expensive process for owners. Despite the potency of Australian venoms, there is potential for novel veterinary therapeutics to be modeled on venom toxins, as has been the case with human pharmaceuticals. A comprehensive overview of envenomation and poisoning signs in livestock and companion animals is provided and related to the potential for venom toxins to act as therapeutics. PMID:25143943

In the period from 1987 to 1996, 103 patients with suicidal benzodiazepines poisoning were treated, including 62 women and 41 men from 16 to 79 (mean 34) years old. 23 persons were poisoned only by benzodiazepines, in 80 remaining cases intoxications were mixed eg. including benzodiazepines and alcohol, tricyclic antidepressants, barbiturates, opioids, phenothiazines. The main causes of suicides were mainly depression, drug addiction and alcoholism. Nobody died in the benzodiazepines group, while mortality rate in the group of mixed poisoning was 4%. Prescribing benzodiazepines by physicians was quite often not justified and facilitated, among others, accumulation of the dose sufficient for suicide attempt. Flumazenil was efficient for leading out from coma in 86% of cases with poisoning only by benzodiazepines and 13% of cases with mixed intoxications mainly containing benzodiazepines and alcohol or carbamazepine.

2005-12-01

To develop an understanding of factors acting as barriers and motivators to parental uptake of child poison safety strategies. A qualitative study involving semistructured interviews and focus groups. A grounded theory approach was used for the collection and analysis of data. Sixty five parents of children under 5 years of age, some of whom had experienced an unintentional child poisoning incident. A range of knowledge based, environmental, and behavioral barriers to comprehensive parental uptake of poison safety practices were identified. As a result there tended to be only partial implementation of safety initiatives in the home. Selection of safety practices was often guided by the interests and behaviors of the child. This made the child vulnerable to changes in the home environment, inadequate supervision, and/or shifts in their own behavior and developmental ability. Personal or vicarious exposure of a parent to a child poisoning incident was a significant motivator for parental review of safety practices. Environmental measures targeting child resistant containers, warning labels, and lockable poisons cupboards will support parents' efforts to maintain poison safety. Additional education campaigns using stories of actual poisoning incidents may help to increase awareness of risk and encourage increased uptake.

2014-01-01

Aconite roots (roots or root tubers of the Aconitum species) are eaten as root vegetables and used to prepare herbal soups and meals, mainly for their purported health benefits. Aconite roots contain aconitine and other Aconitum alkaloids, which are well known cardiotoxins and neurotoxins. To better understand why Aconitum alkaloid poisoning related to the culinary uses of aconite roots can occur and characterize the risks posed by these “food supplements”, relevant published reports were reviewed. From 1995 to 2013, there were eight reports of aconite poisoning after consumption of these herbal soups and meals, including two reports of large clusters of cases (n = 19–45) and two reports of cases (n = 15–156) managed by two hospitals over a period of 4.5 to 5 years. The herbal formulae used did not adhere to the suggested guidelines, with regarding to the doses (50–500 g instead of 3–30 g per person) and types (raw instead of processed) of aconite roots used. The quantities of Aconitum alkaloids involved were huge, taking into consideration the doses of aconite roots used to prepare herbal soups/meals and the amounts of aconite roots and herbal soups/meals consumed. In a large cluster of cases, despite simmering raw “caowu” (the root tuber of A. kusnezoffii) in pork broth for 24 h, all 19 family members who consumed this soup and boiled “caowu” developed poisoning. Severe or even fatal aconite poisoning can occur after consumption of herbal soups and foods prepared from aconite roots. Even prolonged boiling may not be protective if raw preparations and large quantities of aconite roots are used. The public should be warned of the risk of severe poisoning related to the culinary and traditional medicinal uses of aconite roots. PMID:25184557

The quantities of Aconitum alkaloids involved were huge, taking into consideration the doses of aconite roots used to prepare herbal soups/meals and the amounts of aconite roots and herbal soups/meals consumed. In a large cluster of cases, despite simmering raw “caowu” (the root tuber of A. kusnezoffii in pork broth for 24 h, all 19 family members who consumed this soup and boiled “caowu” developed poisoning. Severe or even fatal aconite poisoning can occur after consumption of herbal soups and foods prepared from aconite roots. Even prolonged boiling may not be protective if raw preparations and large quantities of aconite roots are used. The public should be warned of the risk of severe poisoning related to the culinary and traditional medicinal uses of aconite roots.

Over the past decade, smoking behaviors have changed in the US. Hookah or waterpipe smoking is increasing, especially among youth and young adults. Social media sites describe the "hookah high" or "buzz", which may be related to nicotine, carbon monoxide, or other inhalants in hookah smoke. Most important is the risk of carbon monoxide poisoning. Case reports include a high number of victims presenting with loss of consciousness from either syncope or seizures. Anaphylaxis and a very rare respiratory hypersensitivity reaction, acute eosinophilic pneumonia, have also been reported from hookah smoking in previously healthy young adults. This article provides background information on hookah smoking, describes hookah-induced acute injuries that could precipitate poison center calls, and offers suggestions for exposure characterization.

To characterize poison exposures in young Israeli military personnel as reported to the national poison center. Retrospective poison center chart review over a 14-year period. Cases included were Israeli soldiers aged 18-21 years, the compulsory military service age required by the Israeli law. 1770 records of poison exposures in young military personnel were identified. Most exposed individuals involved males (n = 1268, 71.6%). Main routes of exposure were ingestion (n = 854, 48.3%), inhalation (n = 328, 18.6%) and ocular (n = 211, 11.9%). Accidents or misuse (n = 712, 40.2%) were the most frequently reported circumstances, followed by suicide attempts (370, 20.9%), and bites and stings (161, 9.1%). More than half of the cases involved chemicals (n = 939, 53.1%); hydrocarbons, gases and corrosives were the main causative agents. Pharmaceuticals (mainly analgesics) were involved in 519 (29.3%) cases, venomous animals (mainly scorpions, centipedes, and snakes) in 79 (4.5%). Clinical manifestations were reported in 666 (37.6%) cases, mostly gastrointestinal, neurologic, and respiratory. The vast majority of cases (1634, 92.3%) were asymptomatic or mildly affected; no fatalities were recorded. In 831 (46.9%) cases the clinical toxicologist recommended referral to an emergency department; ambulatory observation was recommended in 563 (31.8%) cases, and hospitalization in 86 (4.9%). Our data show that poison exposures among young soldiers involve mainly males, accidents, misuse and suicides, oral route and chemicals; most exposures were asymptomatic or with mild severity. Repeated evaluations of poison center data pertaining to military personnel is advised for identifying trends in poison exposure and characteristics in this particular population.

Within a short period, 14 cases of lead poisoning in the dogs have been encountered. A detailed record appears justified as no published reference can be found to this condition occurring in Britain and because reports from other countries stress the similarity of the clinical manifestations of lead poisoning to those of the common infections of the dog. Five of the 14 clinical cases of lead poisoning are described. The available literature is reviewed and the diagnosis and significance of the condition discussed. 19 references, 2 tables.

Occupational Metallic Mercury Poisoning in Gilders

Directory of Open Access Journals (Sweden)

M Vahabzadeh

2016-04-01

Full Text Available Occupational exposure to elemental mercury vapor usually occurs through inhalation during its utilizations. This leads to a variety of adverse health effects. In some Islamic cities, this type of poisoning may occur during gilding of shrines using elemental mercury with gold. Herein, we report on three male patients aged 20–53 years, who were diagnosed with occupational metallic mercury poisoning due to gilding of a shrine. All patients presented with neuro-psychiatric disorders such as anxiety, loss of memory and concentration, and sleep disorders with high urinary mercury concentrations of 326–760 μg/L upon referring, 3–10 days after cessation of elemental mercury exposure. Following chelating therapy, the patients recovered clinically and their mercury concentrations declined to non-toxic level (<25 μg/L. Health, environmental and labor authorities, as well as the gilders should be aware of the toxicity risk of exposure to metalic mercury during gilding in closed environments and act accordingly.

Many substances deemed too dangerous for commercial use are still available to the general public. The purchase of these substances may potentially place members of the general public at risk for serious poisonings. This study was designed to document the large variety of dangerous poisons readily available on a popular online auction Web site. Methods. Over a 10-month period, the online auction Web site eBays was searched daily using the terms "poison" and "contents." Product name, active ingredients, what form the product is in, amount in container, and relative toxicity rating (Clinical Toxicology of Commercial Products, Gosselin, et al.) were recorded. If available, pictures of the products were saved. One hundred twenty-one individual products were identified. Fifty-five were in solid/tablet form, 37 were powders, and 29 were liquids. Product containers were full for 56 items and partially full for 65. Twenty-four products contained ingredients rated as "supertoxic" and included strychnine (10), arsenic trioxide (8), cyanide (2) and nicotine, pilocarpine, phosphorus, powdered conium maculatum (1 each). Sixty-three products contained "extremely toxic" ingredients including thallium, picrotoxin, soluble barium, antimony, mercury, arsenates, podophyllin, fluoride, zinc phosphide, atropine, scopolamine, and plant extracts of gelsemium, aconite, larkspur, and croton. Twenty-one products contained "very toxic" ingredients including lead, copper, camphor, caffeine, theobromine, creosote, pyrogallic acid, sparteine, quinine, lindane, warfarin, phenol, and digitalis. The remaining 13 were "moderately-slightly toxic." While the viability of the labeled ingredients could not be verified, the transportation, handling, and potential utilization of these dangerous poisons by the general public could result in serious poisonings.

Clinical Profile of Acute Accidental Poisoning Among Children- A Retrospective Study

Directory of Open Access Journals (Sweden)

Tabassum Khatoon

2017-12-01

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.

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

Risk assessment

International Nuclear Information System (INIS)

Kinchin, G.H.

1983-01-01

After defining risk and introducing the concept of individual and societal risk, the author considers each of these, restricting considerations to risk of death. Some probabilities of death arising from various causes are quoted, and attention drawn to the care necessary in making comparisons between sets of data and to the distinction between voluntary and involuntary categories and between early and delayed deaths. The presentation of information on societal risk is discussed and examples given. The history of quantified risk assessment is outlined, particularly related to the nuclear industry, the process of assessing risk discussed: identification of hazard causes, the development of accident chains and the use of event trees, the evaluation of probability through the collection of data and their use with fault trees, and the assessment of consequences of hazards in terms of fatalities. Reference is made to the human element and common-made failures, and to studies supporting the development of reliability assessment techniques. Acceptance criteria are discussed for individual and societal risk in the nuclear field, and it is shown that proposed criteria lead to risks conservative by comparison with risks from day-to-day accidents and other potentially hazardous industries.

Involvement of personality traits in susceptibility to suicidal behaviour has attracted considerable research interest over the past decades. This study was motivated by reports that emotionality may play a potentially confounding role in the association between the personality profile and suicidal behaviour. We assessed the association between personality traits, as measured using the Temperament and Character Inventory (TCI), and suicidal behaviour, while controlling for the effects of Affective Temperaments, measured using the Temperament Evaluation of the Memphis, Pisa, Paris and San Diego auto-questionnaire (TEMPS-A) in a sample of 140 consecutive self-poisoning nonlethal suicide (SNS) attempters admitted to the Emergency Toxicology Clinic, comparing them with a sample of 140 age and sex matched healthy controls. After controlling for Affective Temperaments, the temperament dimension of Novelty Seeking (NS) and the character dimensions of Self-directedness and Self-transcendence remained significantly associated with SNS attempts. NS, in particular, was most consistently and uniquely associated with suicidal behaviour. The present study conveys the difficulty in disentangling the personality profile of SNS attempters from their emotionality. We conclude that the risk associated with certain personality traits is often entirely mediated by Affective Temperaments and few dimensions independently contribute to the risk of self-poisoning nonlethal suicidal behaviour.

Risk assessment is used in many industries to identify and manage risks. Initially developed for use on aeronautical and nuclear systems, risk assessment has been applied to transportation, chemical, computer, financial, and security systems among others. It is used to gain an understanding of the weaknesses or vulnerabilities in a system so modification can be made to increase operability, efficiency, and safety and to reduce failure and down-time. Risk assessment results are primary inputs to risk-informed decision making; where risk information including uncertainty is used along with other pertinent information to assist management in the decision-making process. Therefore, to be useful, a risk assessment must be directed at specific objectives. As the world embraces the globalization of trade and manufacturing, understanding the associated risk become important to decision making. Applying risk assessment techniques to a global system of development, manufacturing, and transportation can provide insight into how the system can fail, the likelihood of system failure and the consequences of system failure. The risk assessment can identify those elements that contribute most to risk and identify measures to prevent and mitigate failures, disruptions, and damaging outcomes. In addition, risk associated with public and environment impact can be identified. The risk insights gained can be applied to making decisions concerning suitable development and manufacturing locations, supply chains, and transportation strategies. While risk assessment has been mostly applied to mechanical and electrical systems, the concepts and techniques can be applied across other systems and activities. This paper provides a basic overview of the development of a risk assessment.

Heterogeneous burnable poisons:

International Nuclear Information System (INIS)

Leiva, Sergio; Agueda, Horacio; Russo, Diego

1989-01-01

The use of materials possessing high neutron absorption cross-section commonly known as 'burnable poisons' have its origin in BWR reactors with the purpose of improving the efficiency of the first fuel load. Later on, it was extended to PWR to compensate of initial reactivity without infringing the requirement of maintaining a negative moderator coefficient. The present tendency is to increase the use of solid burnable poisons to extend the fuel cycle life and discharge burnup. There are two concepts for the burnable poisons utilization: 1) heterogeneously distributions in the form of rods, plates, etc. and 2) homogeneous dispersions of burnable poisons in the fuel. The purpose of this work is to present the results of sinterability studies, performed on Al 2 O 3 -B 4 C and Al 2 O 3 -Gd 2 O 3 systems. Experiments were carried on pressing at room temperature mixtures of powders containing up to 5 wt % of B 4 C or Gd 2 O 3 in Al 2 O 3 and subsequently sintering at 1750 deg C in reducing atmosphere. Evaluation of density, porosity and microstructures were done and a comparison with previous experiences is shown. (Author) [es

Sabatier Catalyst Poisoning Investigation

Nallette, Tim; Perry, Jay; Abney, Morgan; Knox, Jim; Goldblatt, Loel

2013-01-01

The Carbon Dioxide Reduction Assembly (CRA) on the International Space Station (ISS) has been operational since 2010. The CRA uses a Sabatier reactor to produce water and methane by reaction of the metabolic CO2 scrubbed from the cabin air and the hydrogen byproduct from the water electrolysis system used for metabolic oxygen generation. Incorporating the CRA into the overall air revitalization system has facilitated life support system loop closure on the ISS reducing resupply logistics and thereby enhancing longer term missions. The CRA utilizes CO2 which has been adsorbed in a 5A molecular sieve within the Carbon Dioxide Removal Assembly, CDRA. There is a potential of compounds with molecular dimensions similar to, or less than CO2 to also be adsorbed. In this fashion trace contaminants may be concentrated within the CDRA and subsequently desorbed with the CO2 to the CRA. Currently, there is no provision to remove contaminants prior to entering the Sabatier catalyst bed. The risk associated with this is potential catalyst degradation due to trace organic contaminants in the CRA carbon dioxide feed acting as catalyst poisons. To better understand this risk, United Technologies Aerospace System (UTAS) has teamed with MSFC to investigate the impact of various trace contaminants on the CRA catalyst performance at relative ISS cabin air concentrations and at about 200/400 times of ISS concentrations, representative of the potential concentrating effect of the CDRA molecular sieve. This paper summarizes our initial assessment results.

Fission product poisoning in KS-150 reactor operation

1978-01-01

A three-dimensional model of the KS-150 reactor was used to study reactivity changes induced by reactor poisoning with fission products Xe 135 and Sm 149 . A comparison of transients caused by the poisoning showed the following differences: (1) the duration of the transient Xe poisoning (2 days) is shorter by one order of magnitude than the duration of Sm poisoning (20 days); however, the level of Xe poisoning is greater approximately by one order than the level of the Sm poisoning; (2) the level of steady-state Xe poisoning depends on the output level of the reactor; steady-state Sm poisoning does not depend on this level; (3) following reactor shutdown Xe poisoning may increase to the maximum value of up to Δrhosub(Xe)=20% and will then gradually decrease; Sm poisoning may reach maximum values of up to Δrhosub(Sm)=2% and does not decrease.

Williams, Pamela R D; Dotson, G Scott; Maier, Andrew

2012-10-16

Human health risk assessments continue to evolve and now focus on the need for cumulative risk assessment (CRA). CRA involves assessing the combined risk from coexposure to multiple chemical and nonchemical stressors for varying health effects. CRAs are broader in scope than traditional chemical risk assessments because they allow for a more comprehensive evaluation of the interaction between different stressors and their combined impact on human health. Future directions of CRA include greater emphasis on local-level community-based assessments; integrating environmental, occupational, community, and individual risk factors; and identifying and implementing common frameworks and risk metrics for incorporating multiple stressors.

Paraphenylene diamine (PPD) hair dye poisoning is a common health problem in the Middle East and Indian subcontinent. It is the most common cause of suicide intent especially among females. We hereby present a 27-year-old female who presented with a clinical feature of PPD poisoning due to a suicidal attempt, and she died soon after arrival. She had survived a previous suicide attempt with PPD 4 years before. This time she also intentionally tried to kill her four children using PPD. One child died, one recovered after dialysis for acute kidney injury and the other two survived without any further intervention. This case illustrates that PPD poisoning may be used in filicide and suicide intent and that all patients who committed suicide should be reviewed and assessed by clinical psychiatrist. © The Author(s) 2012.

Soman poisoning increases neural progenitor proliferation and induces long-term glial activation in mouse brain

2005-01-01

To date, only short-term glial reaction has been extensively studied following soman or other warfare neurotoxicant poisoning. In a context of cell therapy by neural progenitor engraftment to repair brain damage, the long-term effect of soman on glial reaction and neural progenitor division was analyzed in the present study. The effect of soman poisoning was estimated in mouse brains at various times ranging from 1 to 90 days post-poisoning. Using immunochemistry and dye staining techniques (hemalun-eosin staining), the number of degenerating neurons, the number of dividing neural progenitors, and microglial, astroglial or oligodendroglial cell activation were studied. Soman poisoning led to rapid and massive (post-soman day 1) death of mature neurons as assessed by hemalun-eosin staining. Following this acute poisoning phase, a weak toxicity effect on mature neurons was still observed for a period of 1 month after poisoning. A massive short-termed microgliosis peaked on day 3 post-poisoning. Delayed astrogliosis was observed from 3 to 90 days after soman poisoning, contributing to glial scar formation. On the other hand, oligodendroglial cells or their precursors were practically unaffected by soman poisoning. Interestingly, neural progenitors located in the subgranular zone of the dentate gyrus (SGZ) or in the subventricular zone (SVZ) of the brain survived soman poisoning. Furthermore, soman poisoning significantly increased neural progenitor proliferation in both SGZ and SVZ brain areas on post-soman day 3 or day 8, respectively. This increased proliferation rate was detected up to 1 month after poisoning

2006-01-01

The purpose of our study was to develop a method to identify and prioritize "high-risk" buildings in Chicago that could be targeted for childhood lead poisoning prevention activities. We defined "high-risk" buildings as those where multiple children younger than 6 years with elevated blood lead levels (BLLs) had lived and where lead hazards were previously identified on environmental inspection. By linking 1997-2003 Chicago elevated blood lead surveillance, environmental inspection, and building footprint data, we found that 49,362 children younger than 6 years with elevated BLLs lived at 30,742 buildings. Of those, 67 were "high-risk" buildings and these were associated with 994 children with elevated BLLs. On average, 15 children with elevated BLLs had lived in each building (range: 10-53, median: 13). Almost two thirds (n = 43) of the high-risk buildings had two or more referrals for inspection to the same apartment or housing unit; of those, 40 percent (n = 17) failed to maintain lead-safe status after compliance. Linking blood lead surveillance, environmental inspection, and building footprint databases allowed us to identify individual high-risk buildings. This approach prioritizes lead hazard control efforts and may help health, housing, and environmental agencies in targeting limited resources to increase lead-safe housing for children.

Full Text Available Context Symptoms of methadone poisoning, as one of the most dangerous types of poisoning, are very serious in children. Objectives The aim of this study was to describe causes and clinical symptoms of methadone poisoning in children admitted to hospitals in Iran. Data Sources Relevant studies published in national and international journals before January 29, 2016 were identified by studying the available databases, including PubMed, Web of Sciences, Google Scholar, Scopus, SID, Iranmedex, MagIran, and Irandoc. Study Selection After excluding duplicate, irrelevant, and low-quality articles, relevant papers were entered into the meta-analysis. The prevalence, mean, and standard deviation of methadone poisoning symptoms in children were statistically analyzed, using Stata version 11, and causes of methadone poisoning were presented in tables. Data Extraction Studies with unknown sample sizes, abstracts without access to full text, articles with quality assessment scores below 15.5, and studies carried out on non-Iranian populations were excluded from the meta-analysis. Results During the initial advanced search, 1594 articles were identified. After quality assessment, 12 papers were found eligible for the final systematic review and meta-analysis, based on the inclusion and exclusion criteria. The reported symptoms included drowsiness, vomiting, apnea, cyanosis, seizure, ataxia, and delirium. In the meta-analysis, prevalence of symptoms in referred patients was estimated at 44% (0.95% confidence interval, 0.288 to 0.609. The causes of poisoning in children included accidental feeding by parents, storage of drugs in inappropriate containers, parental addiction, and low educational level of parents. Conclusions It is important to keep methadone in a suitable container away from children. Also, it is essential to focus on educating parents on health issues of their children.

Full Text Available Snake bite envenomation is not uncommon in Taiwan. This study focuses on the pattern of poisonous snake bites and their management in southern Taiwan over a 5-year period. The case histories of 37 patients with poisonous snake bites admitted to the Kaohsiung Medical University Hospital between June 2001 and July 2005 were analyzed retrospectively. Three patients, bitten by unknown species of venomous snakes, were excluded from this study. The frequency of snake bites from each species of snake, the local and systemic manifestations of snake bite, treatment of complications and final outcomes were analyzed. Of the remaining 34 patients, 11 (32.4% were bitten by bamboo vipers, 10 (29.4% by Russell's pit vipers, 8 (23.5% by Taiwan cobras and 5 (14.7% by Taiwan Habu. The majority of snake bites (28 occurred between May and November. Those affected were mainly outdoor hikers (14 and workers (9. The antivenin requirements for treatment in the emergency room were in accordance with standard procedures. No mortality was noted among those envenomed by poisonous snakes. Although poisonous snake bite is not a common life-threatening emergency in the study area, we observed both an environmental risk and a seasonal incidence of snake bite. Keeping the varied clinical manifestations of snake bite in mind is important for effective management. Ready availability and appropriate use of antivenin, close monitoring of patients, institution of ventilatory support and early referral to a larger hospital when required, all help reduce mortality.

Full Text Available Objective: Aim of this study was to retrospectively evaluate poisoning cases in an intensive care unit (ICU in order to determine the profile of poisoning cases, update epidemiological data in Adiyaman, and contribute to data about poisoning in our country. Methods: Between 01-01-2012 and 31-12-2013 174 patients (116 males, 58 females with a mean age of 23.7 years were treated. Demographic characteristics, reasons and ways of poisoning, types of toxic substances, length of their ICU stay and prognosis were evaluated. Results: 2733 patients admitted to the intensive care unit were 174 poisoning cases. Poisoning ways were suicide by drug overdose (n=162, 93.1%, and accidental poisoning (n=12,6.9%.119 patients (66.5% had single drug intake, thirty-three patients (18.4% with multiple drug intake, and 16 (8.9% were poisoned by organic phosphates. The most common drug used for suicide was antidepressants (n=87.5%. 32 patients (18.4% took analgesics and anti-inflammatory drugs. A total of 152 patients taking the drug, 22 patients were poisoned by other means. The median length of patient stay was 2 days (range 1-20 days. Ninety-nine patients (56.9% recovered and were discharged.72 patients (41.4% were admitted to inpatient after intensive care unit. Patients were followed up by asking poisoning suicidal psychiatric consultation.1 patient was followed up for 20 days in intensive care due to alcohol poisoning but was died.2 patients (1.1% were referred to a center forward. Conclusion: Majority of the patients were females, who took drugs with suicidal intention. Frequent use of antidepressants, which are not subject to control by authorities, to commit suicide was remarkable.

Comfrey: assessing the low-dose health risk.

Science.gov (United States)

Abbott, P J

The regular use of comfrey as part of the diet or for medicinal purposes may be a potential health risk as a result of the presence of naturally-occurring pyrrolizidine alkaloids. The majority of these alkaloids are hepatotoxic in both animals and humans, and some have been shown to induce tumours in experimental animals. In this article, the toxic properties of pyrrolizidine alkaloids are reviewed briefly, with particular reference to their presence in comfrey. The acute and long-term health risks at the normally-low levels of comfrey consumption are evaluated and discussed. On the basis of the data that are available currently, the small but significant long-term risk that is associated with the consumption of comfrey justifies the need to limit its intake. This is being achieved by controls under various state Poisons Acts, but also requires further education on the potential dangers of naturally-occurring chemicals of plant origin.

Operational risk assessment.

Science.gov (United States)

McKim, Vicky L

2017-06-01

In the world of risk management, which encompasses the business continuity disciplines, many types of risk require evaluation. Financial risk is most often the primary focus, followed by product and market risks. Another critical area, which typically lacks a thorough review or may be overlooked, is operational risk. This category encompasses many risk exposure types including those around building structures and systems, environmental issues, nature, neighbours, clients, regulatory compliance, network, data security and so on. At times, insurance carriers will assess internal hazards, but seldom do these assessments include more than a cursory look at other types of operational risk. In heavily regulated environments, risk assessments are required but may not always include thorough assessments of operational exposures. Vulnerabilities may linger or go unnoticed, only to become the catalyst for a business disruption at a later time, some of which are so severe that business recovery becomes nearly impossible. Businesses may suffer loss of clients as the result of a prolonged disruption of services. Comprehensive operational risk assessments can assist in identifying such vulnerabilities, exposures and threats so that the risk can be minimised or removed. This paper lays out how an assessment of this type can be successfully conducted.

Full Text Available Chelation therapy has been the major treatment for heavy metal poisoning. Various chelating agents have been developed and tested for treatment of heavy metal intoxications, including mercury poisoning. It has been clearly shown that chelating agents could rescue the toxicity caused by heavy metal intoxication, but the potential preventive role of chelating agents against heavy metal poisoning has not been explored much. Recent paper by Siddiqi and colleagues has suggested a protective role of chelating agents against mercury poisoning, which provides a promising research direction for broader application of chelation therapy in prevention and treatment of mercury poisoning.

Italian Poison Centers answer to approximately 100,000 calls per year. Potentially, this activity is a huge source of data for toxicovigilance and for syndromic surveillance. During the last decade, surveillance systems for early detection of outbreaks have drawn the attention of public health institutions due to the threat of terrorism and high-profile disease outbreaks. Poisoning surveillance needs the ongoing, systematic collection, analysis, interpretation, and dissemination of harmonised data about poisonings from all Poison Centers for use in public health action to reduce morbidity and mortality and to improve health. The entity-relationship model for a Poison Center relational database is extremely complex and not studied in detail. For this reason, not harmonised data collection happens among Italian Poison Centers. Entities are recognizable concepts, either concrete or abstract, such as patients and poisons, or events which have relevance to the database, such as calls. Connectivity and cardinality of relationships are complex as well. A one-to-many relationship exist between calls and patients: for one instance of entity calls, there are zero, one, or many instances of entity patients. At the same time, a one-to-many relationship exist between patients and poisons: for one instance of entity patients, there are zero, one, or many instances of entity poisons. This paper shows a relational model for a poison center database which allows the harmonised data collection of poison centers calls.

Suicidal intention, psychosocial factors and referral to further treatment: A one-year cross-sectional study of self-poisoning

Directory of Open Access Journals (Sweden)

Drottning Per

2010-07-01

Full Text Available Abstract Background Patients treated for self-poisoning have an increased risk of death, both by natural and unnatural causes. The follow-up of these patients is therefore of great importance. The aim of this study was to explore the differences in psychosocial factors and referrals to follow-up among self-poisoning patients according to their evaluated intention. Methods A cross-sectional multicenter study of all 908 admissions to hospital because of self-poisoning in Oslo during one year was completed. Fifty-four percent were females, and the median age was 36 years. The patients were grouped according to evaluated intention: suicide attempts (moderate to high suicide intent, appeals (low suicide intent and substance-use related poisonings. Multinomial regression analyses compared patients based on their evaluated intention; suicide attempts were used as the reference. Results Of all self-poisoning incidents, 37% were suicide attempts, 26% were appeals and 38% were related to substance use. Fifty-five percent of the patients reported previous suicide attempts, 58% reported previous or current psychiatric treatment and 32% reported daily substance use. Overall, patients treated for self-poisoning showed a lack of social integration. Only 33% were employed, 34% were married or cohabiting and 53% were living alone. Those in the suicide attempt and appeal groups had more previous suicide attempts and reported more psychiatric treatment than those with poisoning related to substance use. One third of all patients with substance use-related poisoning reported previous suicide attempts, and one third of suicide attempt patients reported daily substance use. Gender distribution was the only statistically significant difference between the appeal patients and suicide attempt patients. Almost one in every five patients was discharged without any plans for follow-up: 36% of patients with substance use-related poisoning and 5% of suicide attempt patients

The phase-out of leaded gasoline began in Jakarta, Indonesia on July 1, 2001. We evaluated mean blood lead levels (BLLs) and the prevalence of elevated BLLs of Jakarta school children and assessed risk factors for lead exposure in these children before the beginning of the phase-out activities. The study involved a population-based, cross-sectional blood lead survey that included capillary blood lead sampling and a brief questionnaire on risk factors for lead poisoning. A cluster survey design was used. Forty clusters, defined as primary schools in Jakarta, and 15 2nd- and 3rd-grade children in each cluster were randomly selected for participation in the study. The average age of children in this study was 8.6 years (range 6-12) and the geometric mean BLL of the children was 8.6 {mu}g/dl (median: 8.6 {mu}g/dl; range: 2.6-24.1 {mu}g/dl) (n=397). Thirty-five percent of children had BLLs {>=}10 {mu}g/dl and 2.4% had BLLs {>=}20 {mu}g/dl. Approximately one-fourth of children had BLLs 10-14.9 {mu}g/dl. In multivariate models, level of education of the child's primary caregiver, water collection method, home varnishing and occupational recycling of metals, other than lead, by a family member were predictors of log BLLs after adjustment for age and sex. BLLs of children who lived near a highway or major intersection were significantly higher than those of children who lived near a street with little or no traffic when level of education was not included in the model. Water collection method was a significant predictor of BLLs {>=}10 {mu}g/dl after adjustment for age and sex. BLLs in children in this study were moderately high and consistent with BLLs of children in other countries where leaded gasoline is used. With the phase-out of leaded gasoline, BLLs of children in Jakarta are expected to rapidly decline as they have in other countries that have phased lead out of gasoline.

Iwasaki, Toshio; Hasegawa, Koji.

1979-01-01

Purpose: To improve the response function in the reactor scram with no wide space by injecting poisons in soluble poison guide tubes to such a liquid level as giving no effect on usual reactor operation. Constitution: Soluble poison guide tubes in a reactor are connected at their upper ends to a buffer tank and at their lower ends to a pressurizer by way of a header and an injection valve. The header is connected by way of a valve with a level meter, one end of which is connected to the buffer tank. During reactor operation, the injection valve is closed and the soluble poisons in the pressurizer vessel is maintained at a pressurized state and, while on the other hand, soluble poisons are injected by way of the header to the lower end of the soluble poison guide tubes by the opening of a valve, which is thereafter closed. Upon scram, a valve is closed to protect the level meter and pressurized poisons are rapidly filled in the guide tubes by the release of the injection valve. (Kawakami, Y.)

The fuel assemblies with burnable poison are widely used on power reactors, but there are not commonly used on research reactors. This paper shows a neutronic analysis of the advantages and disadvantages of the burnable poison usage on research reactors. This paper analyses both burnable poison design used on research reactors: Boron on the lateral wall and Cadmium wires. Both designs include a parametric study on the design parameters like the amount and geometry of the burnable poison. This paper presents the design flexibility using burnable poisons, it does not find an optimal or final design, which it will strongly depend on the core characteristics and fuel management strategy.

Rothwell, Erin; Ellington, Lee; Planalp, Sally; Crouch, Barbara

2012-01-01

The use of the telephone for providing health care is growing. A significant amount of social meaning is derived from visual information, and the absence of visual stimuli provides unique barriers to communication and increases the risks for misunderstandings and distractions. Understanding challenges to telephone communication can provide insight into training opportunities for overcoming these difficulties and improving patient care. The purpose of this research was to explore through focus groups the challenges of phone communication perceived by specialists in poison information. General types of challenges to effective phone communication included developing new communication skills to compensate for lack of visual information, difficulty assessing caller understanding, difficulty managing caller misunderstandings, maintaining distinctive assessments for routine calls, and managing the multifaceted aspects of job stress. The desire for training to enhance telehealth and cultural competency skills was also mentioned, and these findings might provide guidance for the development of training opportunities for telehealth professionals.

Blood lead (B-Pb), one of the most used toxicological biomarker all kind, has serious limitations. Thus, the objective is to evaluate whether plasma lead (P-Pb) is more adequate. A long-term follow-up study of five cases of lead poisoning. P-Pb was analysed by inductively coupled plasma mass spectrometry. Kinetics after end of exposure was modelled. P-Pb at severe poisoning was about 20 μg/L; haematological effects at about 5 μg/L. Biological half-time of P-Pb was about 1 month; B-Pb decay was much slower. P-Pb is a valuable biomarker of exposure to and risk, particularly at high exposure.

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.

Poisoning of animals by industrial fumes

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.

Amphetamine abuse in human beings has increased, resulting in many reports of toxicity and death. In the US over 4 million people have abused amphetamines at least once, thus small animals are exposed to increased accidental poisoning risk. This report describes an acute amphetamine poisoning in a dog due to ingestion of 15 mg/kg fenproporex, leading to typical signs of catecholamines release and effects in different organ systems. Similar clinical and laboratory findings observed in human beings are reviewed and physiopathogenic mechanisms discussed, as well as the therapeutic approaches available in veterinary medicine.

Poisoning of water fowl due to the intake of lead shot is not rare in the USA. In order to study this kind of poisoning more closely domestic fowl were given varying amounts of lead shot and lead powder. This treatment did not provoke any symptoms of poisoning. Chemical analyses of different organs, muscles, skeleton and eggs yielded low lead values. It is concluded that the low toxicity of lead administered as lead shot to the domestic fowl is due to a low absorption rate from the gastro-intestinal tract.

2015-03-01

Full Text Available Information on intoxication of livestock by plants in Brazil, in terms of cause, clinical signs and pathology, is compared with information on livestock poisoning by plants in South Africa. Plant poisoning, including mycotoxicosis, is considered to be one of three major causes of death in livestock in Brazil, which is one of the top beef producing countries in the world, with a cattle population of more than 200 million. Cattle production in South Africa is on a more modest scale, but with some 600 species of plants and fungi known to cause toxicity in livestock, as opposed to some 130 species in Brazil, the risk to livestock in South Africa appears to be much greater. The comparisons discussed in this communication are largely restricted to ruminants.

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 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.

GM Risk Assessment

Sparrow, Penny A. C.

GM risk assessments play an important role in the decision-making process surrounding the regulation, notification and permission to handle Genetically Modified Organisms (GMOs). Ultimately the role of a GM risk assessment will be to ensure the safe handling and containment of the GMO; and to assess any potential impacts on the environment and human health. A risk assessment should answer all ‘what if’ scenarios, based on scientific evidence.

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.

It is proposed to employ a liquid poison injection system as an emergency shut down device for R-5 reactor. The liquid poison consists of gadolinium nitrate solution, which is injected into twenty poison tubes made of zircaloy that are located in between the regular lattice positions in R-5 reactor. The calculational model adopted to estimate the reactivity worth of the poison tubes so as to hold the reactor subcritical by 50 mk at full tank, is described. Similar reactivity estimates have also been carried out for R-5 poison tubes installed in Zerlina reactor in order to assess the adequacy of the calculational mode. The results of the calculations are compared with experimental values for single poison tubes. (author)

Interrupted time-series analysis of regulations to reduce paracetamol (acetaminophen poisoning.

Directory of Open Access Journals (Sweden)

Oliver W Morgan

2007-04-01

Full Text Available Paracetamol (acetaminophen poisoning is the leading cause of acute liver failure in Great Britain and the United States. Successful interventions to reduced harm from paracetamol poisoning are needed. To achieve this, the government of the United Kingdom introduced legislation in 1998 limiting the pack size of paracetamol sold in shops. Several studies have reported recent decreases in fatal poisonings involving paracetamol. We use interrupted time-series analysis to evaluate whether the recent fall in the number of paracetamol deaths is different to trends in fatal poisoning involving aspirin, paracetamol compounds, antidepressants, or nondrug poisoning suicide.We calculated directly age-standardised mortality rates for paracetamol poisoning in England and Wales from 1993 to 2004. We used an ordinary least-squares regression model divided into pre- and postintervention segments at 1999. The model included a term for autocorrelation within the time series. We tested for changes in the level and slope between the pre- and postintervention segments. To assess whether observed changes in the time series were unique to paracetamol, we compared against poisoning deaths involving compound paracetamol (not covered by the regulations, aspirin, antidepressants, and nonpoisoning suicide deaths. We did this comparison by calculating a ratio of each comparison series with paracetamol and applying a segmented regression model to the ratios. No change in the ratio level or slope indicated no difference compared to the control series. There were about 2,200 deaths involving paracetamol. The age-standardised mortality rate rose from 8.1 per million in 1993 to 8.8 per million in 1997, subsequently falling to about 5.3 per million in 2004. After the regulations were introduced, deaths dropped by 2.69 per million (p = 0.003. Trends in the age-standardised mortality rate for paracetamol compounds, aspirin, and antidepressants were broadly similar to paracetamol

Poison or cure: meanings of medication in schizophrenia.

Science.gov (United States)

Rosenfield, Paul J

2007-01-01

Antipsychotic medications provide tremendous relief to many individuals with schizophrenia, but can have significant costs, including adverse metabolic, neurological, and psychological effects. Prescribers and consumers of these medications often have different perceptions of the safety and utility of medications, ranging from "poison" to "cure." While much of the literature on the meaning of medication in schizophrenia discusses patients' negative perceptions of medication, poor insight, and other risk factors for nonadherence, a variety of additional factors should be considered, including both doctors' and patients' perspectives. Historical, cultural, and scientific, as well as individual factors, influence both the prescribing and taking of antipsychotic medications. The relationship between doctors and patients, as informed by these factors, plays a central role in the creation of the meanings of medications. An understanding of this relationship can help to establish more collaborative treatment relationships, beyond the dichotomy of poison or cure.

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.

Transdermal carbamate poisoning – a case of misuse

Directory of Open Access Journals (Sweden)

Lalit Kumar Rajbanshi

2017-01-01

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.

Offshore risk assessment

CERN Document Server

Vinnem, Jan-Erik

2014-01-01

  Offshore Risk Assessment was the first book to deal with quantified risk assessment (QRA) as applied specifically to offshore installations and operations. Risk assessment techniques have been used for more than three decades in the offshore oil and gas industry, and their use is set to expand increasingly as the industry moves into new areas and faces new challenges in older regions.   This updated and expanded third edition has been informed by a major R&D program on offshore risk assessment in Norway and summarizes research from 2006 to the present day. Rooted with a thorough discussion of risk metrics and risk analysis methodology,  subsequent chapters are devoted to analytical approaches to escalation, escape, evacuation and rescue analysis of safety and emergency systems.   Separate chapters analyze the main hazards of offshore structures: fire, explosion, collision, and falling objects as well as structural and marine hazards. Risk mitigation and control are discussed, as well as an illustrat...

Demographic consequences of poison-related mortality in a threatened bird of prey.

Directory of Open Access Journals (Sweden)

Simone Tenan

Full Text Available Evidence for decline or threat of wild populations typically comes from multiple sources and methods that allow optimal integration of the available information, representing a major advance in planning management actions. We used integrated population modelling and perturbation analyses to assess the demographic consequences of the illegal use of poison for an insular population of Red Kites, Milvus milvus. We first pooled into a single statistical framework the annual census of breeding pairs, the available individual-based data, the average productivity and the number of birds admitted annually to the local rehabilitation centre. By combining these four types of information we were able to increase estimate precision and to obtain an estimate of the proportion of breeding adults, an important parameter that was not directly measured in the field and that is often difficult to assess. Subsequently, we used perturbation analyses to measure the expected change in the population growth rate due to a change in poison-related mortality. We found that poison accounted for 0.43 to 0.76 of the total mortality, for yearlings and older birds, respectively. Results from the deterministic population model indicated that this mortality suppressed the population growth rate by 20%. Despite this, the population was estimated to increase, albeit slowly. This positive trend was likely maintained by a very high productivity (1.83 fledglings per breeding pair possibly promoted by supplementary feeding, a situation which is likely to be common to many large obligate or facultative European scavengers. Under this hypothetical scenario of double societal costs (poisoning of a threatened species and feeding programs, increasing poison control would help to lower the public cost of maintaining supplementary feeding stations.

Depletion optimization of lumped burnable poisons in pressurized water reactors

International Nuclear Information System (INIS)

Kodah, Z.H.

1982-01-01

Techniques were developed to construct a set of basic poison depletion curves which deplete in a monotonical manner. These curves were combined to match a required optimized depletion profile by utilizing either linear or non-linear programming methods. Three computer codes, LEOPARD, XSDRN, and EXTERMINATOR-2 were used in the analyses. A depletion routine was developed and incorporated into the XSDRN code to allow the depletion of fuel, fission products, and burnable poisons. The Three Mile Island Unit-1 reactor core was used in this work as a typical PWR core. Two fundamental burnable poison rod designs were studied. They are a solid cylindrical poison rod and an annular cylindrical poison rod with water filling the central region.These two designs have either a uniform mixture of burnable poisons or lumped spheroids of burnable poisons in the poison region. Boron and gadolinium are the two burnable poisons which were investigated in this project. Thermal self-shielding factor calculations for solid and annular poison rods were conducted. Also expressions for overall thermal self-shielding factors for one or more than one size group of poison spheroids inside solid and annular poison rods were derived and studied. Poison spheroids deplete at a slower rate than the poison mixture because each spheroid exhibits some self-shielding effects of its own. The larger the spheroid, the higher the self-shielding effects due to the increase in poison concentration

over a period of 2 years. RESULTS AND CONCLUSION: The overall suicide rate was 71.4 per 100 000 population; the highest burden was among men. Most people died through hanging (81, 54%) and self-poisoning (46, 31%). Of the 46 who died from self-poisoning, 78.3% had taken pesticides and 19.7% had eaten...... poisonous plants. Eighty per cent of the self-poisoning cases obtained the poisonous substance in or in close proximity to the home, highlighting the importance of safe storage in the domestic environment. Of the 110 fatal and non-fatal self-poisoning cases, 87 (57.5%) were taken for treatment; 50 (57.......4%) went to government hospitals and 37 (42.5%) to private facilities. This indicates the importance of including the private sector in the efforts to improve case management. Furthermore, the fact that 31 (67%) of the self-poisoning patients, who eventually died, were alive after 4 h provides an incentive...

Why Do Parents with Toddlers Store Poisonous Products Safely?

Directory of Open Access Journals (Sweden)

Tinneke M. J. Beirens

2010-01-01

Full Text Available Unintentional poisoning is a major cause of nonfatal injuries in children aged 0–24 months. Associations between self-reported habits on the child safe storage of medication and cleaning products and family, and psychosocial factors were assessed, using a model based on the Protection Motivation Theory. By identifying correlates of safety behavior in this manner, more insight in factors which influence this behavior is obtained. Health promotion activities in order to promote safety behavior should address these factors in order to increase the effectiveness of the health message. Data were gathered from a cross-sectional survey using self-administered questionnaires, mailed to a population sample of 2470 parents with toddlers. The results indicate that the promotion of safe storage of medication and cleaning products should address the family situation, personal cognitive factors as well as social factors. Interventions should particularly focus on parents' self-efficacy of storing poisonous products in a child safe manner and on the vulnerability of their child in their home concerning an unintentional poisoning incident.

Cardiac Glycoside Plants Self-Poisoning

2014-06-01

Full Text Available Cardiac glycosides are found in a diverse group of plants including Digitalis purpurea and Digitalis lanata (foxgloves, Nerium oleander, Convallaria majalis (lily of the valley, Strophanthus gratus, etc. Nerium Oleander is an indoor and ornamental plant of an evergreen shrub. It’s widespread in countries with a Mediterranean climate. Oleander is one of the most poisonous plants known to humans. All parts of the nerium oleander are poisonous, primarily due to the contained cardiac glycosides - oleandrin, nerin, digitoxigenin, and olinerin of which oleandrin is the principal toxin. The bark contains the toxic substances of rosagenin which causes strychnine-like effects. Signs of poisoning appear a few hours after the adoption of the parts of the plant. Two cases of Nerium Oleander poisoning were presented. Clinical picture included gastrointestinal, cardiovascular and central nervous system effects. The clinical symptoms were characterized by nausea, vomiting, salivation, colic, diarrhoea, ventricular tachycardia, dysrhythmia, heart block, ataxia, drowsiness, muscular tremor. Treatment included administration of activated charcoal, symptomatic and supportive care.

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

Purpose: To enable to optionally vary the excess reactivity and fuel reactivity. Method: Burnable poisons with a large neutron absorption cross section are contained in fuel material, by which the excess reactivity at the initial stage in the reactor is suppressed by the burnable poisons and the excess reactivity is released due to the reduction in the atomic number density of the burnable poisons accompanying the burning. The burnable poison comprises spherical or rod-like body made of a single material or spherical or rod-like member made of a plurality kind of materials laminated in a layer. These spheres or rods are dispersed in the fuel material. By adequately selecting the shape, combination and the arrangement of the burnable poisons, the axial power distribution of the fuel rods are flattened. (Moriyama, K.)

2009-01-01

In the nights of 19 to 21 August, 2006, highly toxic waste products were dumped at various sites in Abidjan, and numerous cases of poisoning were reported to the health authorities, who were unprepared for such a problem. The research group on Environment and Health in Urban Environment from the Swiss Center of Scientific Research and its partners at the Swiss Tropical Institute undertook this study whose objectives were to: describe the epidemiologic profile of the people poisoned; identify the main clinical symptoms and the risk factors for poisoning; and recommend steps to attenuate the effects and to prevent intermediate- and long-term consequences. This cross-sectional study examined the populations living around the discharge sites (n=6). The sample size was calculated at 619 people per site, to identify a 1% risk and a standard error of 0.4%, because of variability of the human impact factor at the different sites. Households were chosen at each site by the transect technique. Six teams, each including a physician, a public health agent and a local guide collected the data, after specific training. A pilot investigation made it possible to validate the final questionnaire. Of 4573 people surveyed, 4344 people, about 95%, were home during the toxic waste discharge. In all, 2369 (51.8%) had signs of poisoning. Sex, district of residence, and presence at home at the time of the discharge were all statistically related to poisoning. The distribution of poison victims according to health centre shows that 1297 people (64.4%) visited a health center AA(3/4) 615 of them (about 47.4%) a public or official centre, and 778 (about 60%), an unofficial centre; 379 (29.2%) were managed by an NGO, 159 individuals (12.3%) by mobile units, 63 individuals (4.8%) by the unofficial public health centre, and 35 (2.7%) at an unspecified site. Of those who sought care, 673 people (about 51.8%) received a medical prescription, and 815 (or 62.7%) had been given the drug directly

Concept of risk: risk assessment and nuclear safety

International Nuclear Information System (INIS)

Thompson, P.B.

1980-01-01

The dissertation is a critical examination of risk assessment and its role in public policy. Nuclear power safety safety issues are selected as the primary source of illustrations and examples. The dissertation examines how risk assessment studies develop a concept of risk which becomes decisive for policy choices. Risk-assessment techniques are interpreted as instruments which secure an evaluation of risk which, in turn, figures prominently in technical reports on nuclear power. The philosophical critique is mounted on two levels. First, an epistemological critique surveys distinctions between the technical concept of risk and more familiar senses of risk. The critique shows that utilization of risk assessment re-structures the concept of risk. The technical concept is contrasted to the function of risk within a decision-maker's conceptual agenda and hierarchy of values. Second, an ethical critique exposes the value commitments of risk assessment recommendations. Although some of these values might be defended for policy decisions, the technical character of risk assessment obfuscates normative issues. Risk assessment is shown to be a form of factual enquiry which, nonetheless, represents a commitment to a specific selection of ethical and social values. Risk assessment should not be interpreted as a primary guide to decision unless the specific values incorporated into its concept of risk are stated explicitly and justified philosophically. Such a statement would allow value questions which have been sublimated by the factual tone of the analytic techniques to be debated on clear, social and ethical grounds

Burnable poison management in a HTR

Pedersen, J

1971-09-21

It is the purpose with this paper to describe the state-of-the-art of burnable poison investigations made within the Dragon Project and to give the results of a number of calculations, which show that it is possible to control the large initial surplus reactivity of the first core and the radial power distribution with two types of burnable poison sticks with Gadolinium (one type of stick to be used in the inner core region, the other in the outer core region), where the poison will burn away so that keff always stays around the desired value 1.03, and with the radial form-factor not exceeding 1.20. The calculations made for this paper are not too accurate, especially the chosen timestep for calculating the burn-up of the burnable poison stick proved to be too large. Nevertheless, the calculations are good enough to draw the above mentioned conclusions, although they have not given the concentration of Gadolinium to be used in the burnable poison sticks very accurately.

Whilst lead poisoning in raptors, scavenging birds and waterfowl is well studied and common knowledge, there is surprisingly little literature detailing the risk to mammalian scavengers and captive carnivores fed hunted meat. This case report describes the death of two captive cheetahs (Acinonyx jubatus jubatus) following acute onset of nervous symptoms. Clinical signs included hyper-excitability, seizures, arched back, tail held abnormally high and hyper-salivation. Necropsy findings included bullets or a bullet in their stomachs. Kidney and liver lead levels from one cheetah (15.6 ppm and 17 ppm respectively) were consistent with a diagnosis of lead poisoning; liver from the second cheetah was not available for testing. Both animals were routinely fed hunted antelope or game birds. This is the first report of oral lead poisoning in captive large carnivores, although these are unlikely to be the first cases. Without awareness of the risks of feeding hunted game, lead exposure will continue to be an underdiagnosed reality in the rehabilitation of endangered carnivores.

Quebec launched a public health campaign for the Montreal region to prevent carbon monoxide poisoning. The objectives of the campaign were to communicate the dangers of carbon monoxide poisoning, its potential sources, its effects on public health, and the means to prevent poisoning. Its purpose was to inform the public of the risks and strategies to be used in case of carbon monoxide poisoning and to lay out the merits of household carbon monoxide alarms. The communication was done by way of the media, in cooperation with community organizations and school boards. Other tools used in the campaign included the Internet, flyers and press releases. A poll taken in 2008 showed that 59 per cent of the respondents had one or more sources for carbon monoxide in their homes, including fireplaces, and that 28 per cent had a functioning alarm for carbon monoxide detection. A future survey will be held to follow-up on the evolution of the campaign. The development of various activities will help decrease the risk of carbon monoxide poisoning. tabs., figs.

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 Apart from approved or planned poisoning with agricultural purpose, an increase in the number of cases of intentional animal poisoning (primarily referring to cats and dogs has been detected in Serbia, and it is suspected that their number is significantly larger than the one shown by the official statistics data. Under the conditions prescribed by the Criminal Code of the Republic of Serbia, such activities may represent the crime of killing and torture of animals, but also the crime of causing a general danger. It would be impossible to conduct the procedure of discovering and proving these criminal offences and the responsibility of their perpetrators without findings and opinion of forensic veterinary-medicine experts. They play an important role when it comes to site inspection, crime scene processing, collecting the samples from the crime scene, processing of samples and autopsy and exhumation of a potentially poisoned animal body. Just like other evidence in criminal procedure, findings and opinion of experts of veterinary medicine are estimated in accordance with the principle of free assessment of evidence. However, due to the specificity of such cases of killing and torture of animals, their impact on court’s decision on the existence of criminal offence and perpetrator’s liability is crucial. In this paper, the authors discuss the scope of animal poisoning in Serbia, particularly in Belgrade, analyze possible criminal - legal consequences of these illegal activities and point out to a significant role that experts of veterinary medical profession have in discovering and proving such cases and the liability of their perpetrators.

The number of cases of lead poisoning (LP), a widely known disease with various aetiologies, being reported globally has decreased over the years due to both limited domestic applications of lead and enforcement of stringent safety measures. However, a new presentation of lead poisoning, lead-contaminated opium (LCO), is gradually emerging in our region. This study aimed to determine the prevalence and clinical effects of lead toxicity associated with opium use. Between November 2006 and December 2007, all patients diagnosed with LP at a central laboratory in Tehran, Iran, were assessed for potential causes of poisoning. Patients with a history of LCO abuse were evaluated and recruited for the study. Overall, there were 240 patients with LP, and poisoning from LCO was diagnosed in 25 patients. The duration of addiction was between three months and 40 years, and the duration of symptoms was 28.1 ± 17.7 days. Mean blood lead levels of the patients were 145 ± 61 (range 61-323) μg/dL. The average creatinine and haemoglobin levels were 77.4 ± 8.1 μmol/L and 105 ± 25 g/L, respectively. The association between the duration of addiction and levels of lead in blood was not statistically significant (r = -0.142, p = 0.54). The most common symptoms were gastrointestinal complaints, followed by musculoskeletal complaints with muscle weakness (92%). Anorexia was also a leading complaint. The results of our study suggest that the possibility of LP should be considered with high suspicion among opium users presenting with acute abdominal symptoms.

Full Text Available Amitraz is an insecticide compound used worldwide for controlling pests, especially in agricultural and livestock areas. However, amitraz poisoning in Colombia is rare. This article reports the case of an 18-year-old female patient who was admitted in the emergency service 3 hours after the intake of an unknown amount of Triatox® (amitraz. The patient presented with a depressed level of consciousness, respiratory distress, hypotension, bradycardia, myosis and metabolic acidosis compensated with respiratory alkalosis. Initial treatment was provided using life support measures in the emergency ward, and subsequent transfer and support in the intensive care unit. She was discharged 24 hours after admission. This case considers the clinical similarity between amitraz poisoning and poisoning caused by other more frequent toxic compounds such as carbamates, organophosphates and opioids, which require different management.

State of risk assessment

1978-03-01

In view of the growing importance assumed in recent years by scientific work on the calculation, quantification, evaluation and acceptance as well as behavior in the face of risks in general and more specifically, the risks of large industrial plants, the report attempts to provide a survey of the current situation, results and evaluation of this new branch of research, risk assessment. The emphasis of the report is on the basic discussion and criticism of the theoretical and methodological approaches used in the field of risk assessment (section 3). It is concerned above all with - methodical problems of determining and quantifying risks (3.1) - questions of the possibility of risk evaluation and comp arison (3.1, 3.2) - the premises of normative and empirical studies on decision making under risk (3.2, 3.3) - investigations into society's acceptance of risks involved in the introduction of new technologies (3.4) - attempts to combine various aspects of the field of risk assessment in a unified concept (3.5, 3.6, 3.7). Because risk assessment is embedded in the framework of decision theory and technology assessment, it can be implicitly evaluated at a more general level within this framework, as far as its possibilities and weaknesses of method and application are concerned (section 4). Sections 2 and 5 deal with the social context of origin and utilization of risk assessment. Finally, an attempt is made at a summary indicating the possible future development of risk assessment.

Burnable poison rods attached to spent fuels are contained in a containing box and transported to a receiving pool. The burnable poison rod-containing box is provisionally situated by the operation to a handling device to a provisional setting rack in a cutting pool and attached to a cutting guide of a cutting device upon cutting. The burnable poison rod is cut only in a cutting pool water and tritium generated upon cutting is dissolved into the cutting pool water. Diffusion of tritium is thus restricted. Further, the cutting pool is isolated by a partition device from the receiving pool during cutting of the burnable poison rod. Accordingly, water in which tritium is dissolved is inhibited from moving to the receiving pool and prevail of tritium contamination can be avoided. (T.M.)

Emergencies due to snakebites, although unusual in Spain, are potentially serious. Of the 13 species native to the Iberian peninsula, only 5 are poisonous: 2 belong to the Colubridae family and 3 to the Viperidae family. Bites from these venemous snakes can be life-threatening, but the venomous species can be easily identified by attending to certain physical traits. Signs denoting poisoning from vipers, and the appropriate treatment to follow, have changed in recent years.

Risk assessment and risk management of mycotoxins.

Science.gov (United States)

2012-01-01

Risk assessment is the process of quantifying the magnitude and exposure, or probability, of a harmful effect to individuals or populations from certain agents or activities. Here, we summarize the four steps of risk assessment: hazard identification, dose-response assessment, exposure assessment, and risk characterization. Risk assessments using these principles have been conducted on the major mycotoxins (aflatoxins, fumonisins, ochratoxin A, deoxynivalenol, and zearalenone) by various regulatory agencies for the purpose of setting food safety guidelines. We critically evaluate the impact of these risk assessment parameters on the estimated global burden of the associated diseases as well as the impact of regulatory measures on food supply and international trade. Apart from the well-established risk posed by aflatoxins, many uncertainties still exist about risk assessments for the other major mycotoxins, often reflecting a lack of epidemiological data. Differences exist in the risk management strategies and in the ways different governments impose regulations and technologies to reduce levels of mycotoxins in the food-chain. Regulatory measures have very little impact on remote rural and subsistence farming communities in developing countries, in contrast to developed countries, where regulations are strictly enforced to reduce and/or remove mycotoxin contamination. However, in the absence of the relevant technologies or the necessary infrastructure, we highlight simple intervention practices to reduce mycotoxin contamination in the field and/or prevent mycotoxin formation during storage.

Lead poisoning

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.

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. This retrospective study involved acutely poisoned patients, 0-18 years of age, who presented to the ASU-PTC between 1 January 2009 and 31 December 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. 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; 4196 (11%) were 6-12 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. Poisoning in preschool children is mainly unintentional and commonly due to nonpharmaceutical agents whereas poisoning in adolescents is mainly intentional (self-harm). Pesticides, mainly organophosphorous compounds and carbamates, were the most frequent agents leading to morbidity and mortality.

This article provides an overview of the Poisonous Plant Research Laboratory (PPRL), about the unique services and activities of the PPRL and the potential assistance that they can provide to plant poisoning incidences. The PPRL is a federal research laboratory. It is part of the Agricultural Research Service, the in-house research arm of the U.S. Department of Agriculture. The mission of the PPRL is to identify toxic plants and their toxic compounds, determine how the plants poison animals, and develop diagnostic and prognostic procedures for poisoned animals. Furthermore, the PPRL's mission is to identify the conditions under which poisoning occurs and develop management strategies and treatments to reduce losses. Information obtained through research efforts at the PPRL is mostly used by the livestock industry, natural resource managers, veterinarians, chemists, plant and animal scientists, extension personnel, and other state and federal agencies. PPRL currently has 9 scientists and 17 support staff, representing various disciplines consisting of toxicology, reproductive toxicology, veterinary medicine, chemistry, animal science, range science, and plant physiology. This team of scientists provides an interdisciplinary approach to applied and basic research to develop solutions to plant intoxications. While the mission of the PPRL primarily impacts the livestock industry, spinoff benefits such as development of animal models, isolation and characterization of novel compounds, elucidation of biological and molecular mechanisms of action, national and international collaborations, and outreach efforts are significant to biomedical researchers. The staff at the PPRL has extensive knowledge regarding a number of poisonous plants. Although the focus of their knowledge is on plants that affect livestock, oftentimes, these plants are also poisonous to humans, and thus, similar principles could apply for cases of human poisonings. Consequently, the information provided

Laboratories that work with biological agents need to manage their safety risks to persons working the laboratories and the human and animal community in the surrounding areas. Biosafety guidance defines a wide variety of biosafety risk mitigation measures, which include measures which fall under the following categories: engineering controls, procedural and administrative controls, and the use of personal protective equipment; the determination of which mitigation measures should be used to address the specific laboratory risks are dependent upon a risk assessment. Ideally, a risk assessment should be conducted in a manner which is standardized and systematic which allows it to be repeatable and comparable. A risk assessment should clearly define the risk being assessed and avoid over complication.

Food poisoning due to wild wasp broods ingestion has long been noted in the upstream region of the Lancang river valley, Yunnan province, China. This study describes the epidemiological and clinical features of the poisoning and possible causes. Surveillance data collected between 2008 and 2016 were analyzed to produce demographic data on patients, information on clinical presentations, wasp species identification, and estimations of possible risk factors for symptomatic cases. Eleven poisoning events were associated with the ingestion of wild wasp broods, including 46 exposed persons with 31 symptomatic living cases and 8 deceased cases that were reported in the Yunnan province between 2008 and 2016. Poisoning cases were only detected in the upstream region of the Lancang river valley in the autumn. The severity of the symptoms was correlated with an evident dose-effect relationship regarding the quantity ingested. The mean latent period from wild wasp broods ingestion to the onset of the symptoms was 10 h for symptomatic living cases and 7 h for deceased cases, respectively. Both gastrointestinal and neurological symptoms were commonly observed in the poisoning cases. The toxin source may be indirectly caused by the wasp broods due to the prevalence of local poisonous plants, such as Tripterygium wilfordii Hook F, Tripterygium hypoglaucum Hutch and Vaccinium bracteatum Thunb. Educational programs at the start of wasp harvest season in September in the high-risk area should be carried out to reduce the incidence of poisonings. Copyright © 2018 Elsevier Ltd.

Nitric acid (HNO 3 ) is a corrosive fluid that, when in contact with reducing agents, generates nitrogen oxides that are responsible for inhalation poisoning. We present two cases of poisoning from nitric acid gas inhalation resulting from occupational exposure. Imaging findings were similar in both cases, consistent with adult respiratory distress syndrome (ARDS): bilaterally diffuse alveolar opacities on the chest X-ray and a cobblestone pattern on computed tomography (CT).one of the patients died while the other evolved satisfactorily after treatment with n-acetyl cysteine and mechanical ventilation. The diagnosis of nitric acid poisoning was made on the basis of the history of exposure and the way in which the radiological findings evolved.

Burnable poison management in light water reactor lattices

Energy Technology Data Exchange (ETDEWEB)

Buenemann, D; Mueller, A

1970-07-01

For a better reactivity control and power flattening as well as for an increase in dynamic stability the use of burnable poisons in light water reactors has been considered. The main goals for a burnable poison management and its technological realisation are discussed. The poison is assumed to be in the form of separate poison rods or homogeneous or inhomogeneous poisoning in the fuel rods. A new concept with a central poison rod within the fuel rod is discussed. The balance-equation for the needed concentration of burnable poisons for reactivity central as well as the problems of optimization of lumped poisons are treated in connection with the fuel lattice burnup. A first approximation for the design is found. For the calculation of the microburnup of lumped poison and fuel the special code NEUTRA has been developed. The burnup-equation can be chosen either in a simplified burnup-version with 2 pseudo fission products for each fissionable isotope or with an extended system of burnup equations to be used at sophisticated calculations. These burnup equations are coupled to S{sub N}-routines optionally for cylindrical or x-y-geometry for the proper calculation of the microscopic isotope density-, flux-, and power distributions. The theoretical predictions have been checked by means of special experiments so as to determine the accuracy of the computations. Even for a relatively long burnup of the fuel the predicted values are found to be within the experimental error in the case of lumped rods containing a cadmium-alloy or boron carbide. (auth)

To identify age-adjusted poisoning episode rates, and poison control center contacts due to poisonings in children under 6 years old based on 1997-1999 National Health Interview Survey data; and compare findings with 1997-1999 Toxic Exposure Surveillance System data. Secondary analysis of National Health Interview Survey poisoning episode data for children 5 years and younger. Respondents were asked about poison exposures during the previous 3 months. Based on National Health Interview Survey population weighted data there were 196/10,000 poisonings to young children < 6 years. These exposures resulted primarily from harmful solid or liquid substances. A poison control center was called in 86% of exposures to children < 4 years, but only in 70% of the 4-5 year old exposures. The odds of a poison control center not being called were 3.2 times greater for 4-5 year olds (compared to < or = 3 years) and 4.5 times greater for African-American (compared with White-Americans). Comparison of National Health Interview Survey data with data in the 1997-1999 Annual Reports of the Toxic Exposure Surveillance System revealed the number of estimated exposures in the National Health Interview Survey data were approximately half those reported in the Toxic Exposure Surveillance System data. In both datasets, children 1-2 years of age had the highest percent of poisoning exposures. Using multiple datasets to explore poisoning rates in young children provides a broader perspective. Differences in findings reflect divergent data collection methods and biases inherent in each database. Although the majority of National Health Interview Survey respondents reporting contacting a poison control center for a poisoning exposure, rates are lower in specific subgroups indicating a need for targeted educational efforts.

Introduction Poisoning, specifically unintentional poisoning, is a major public health problem in the United States (U.S.). Published literature that presents epidemiology of all forms of poisoning mortalities (i.e., unintentional, suicide, homicide) together is limited. This report presents data and summarizes the evidence on poisoning mortality by demographic and geographic characteristics to describe the burden of poisoning mortality and the differences among sub-populations in the U.S. for a 5-year period. Methods Using mortality data from the Center for Disease Control and Prevention's Web-based Injury Statistics Query and Reporting System, we presented the age-specific and age-adjusted unintentional and intentional (suicide, homicide) poisoning mortality rates by sex, age, race, and state of residence for the most recent years (2003–2007) of available data. Annual percentage changes in deaths and rates were calculated, and linear regression using natural log were used for time-trend analysis. Results There were 121,367 (rate=8.18 per 100,000) unintentional poisoning deaths. Overall, the unintentional poisoning mortality rate increased by 46.9%, from 6.7 per 100,000 in 2003 to 9.8 per100.000 in 2007, with the highest mortality rate among those aged 40–59 (rate=15.36), males (rate=11.02) and whites (rate=8.68). New Mexico (rate=18.2) had the highest rate. Unintentional poisoning mortality rate increased significantly among both sexes, and all racial groups except blacks (p<0.05 time-related trend for rate). Among a total of 29,469 (rate=1.97) suicidal poisoning deaths, the rate increased by 9.9%, from 1.9 per 100,000 in 2003 to 2.1 per 100,000 in 2007, with the highest rate among those aged 40–59 (rate=3.92), males (rate=2.20) and whites (rate=2.24). Nevada (rate=3.9) had the highest rate. Mortality rate increased significantly among females and whites only (p<0.05 time-related trend for rate). There were 463 (rate=0.03) homicidal poisoning deaths and the

The use of lead (Pb) ammunition in the form of shot pellets has been identified as a Pb exposure risk in wildlife and their human consumers. We explore the hypothesis that Pb shot ban enforcement reduces the risk of avian Pb poisoning as well as Pb exposure in game meat consumers. We assessed compliance with a partial ban on Pb shot commencing in 2003 by examination of 937 waterbirds harvested by hunters between 2007 and 2012 in the Ebro delta (Spain). Prevalence of Pb shot ingestion was determined, as were Pb concentrations in liver and muscle tissue to evaluate the potential for Pb exposure in game meat consumers. Hunted birds with only embedded Pb shot (no steel) declined from 26.9% in 2007-08 to meat (0.1μg/g wet weight) in the 2008-09 season, when Pb shot ingestion prevalence was also at a minimum (5.1%). Effective restrictions in Pb ammunition use have a dual benefit since this reduces Pb exposure for game meat consumers due to embedded ammunition as well as reducing Pb poisoning in waterbirds.

Fuel assembly and burnable poison rod

International Nuclear Information System (INIS)

Hirukawa, Koji.

1993-01-01

In a fuel assembly having burnable poison rods arranged therein, the burnable poison comprises an elongate small outer tube and an inner tube coaxially disposed within the outer tube. Upper and lower end tubes each sealed at one end are connected to both of the upper and lower ends in the inner and the outer tubes respectively. A coolant inlet hole is disposed to the lower end tube, while a coolant leakage hole is disposed to the upper end tube. Burnable poison members are filled in an annular space. Further, the burnable poison-filling region is disposed excepting portions for 1/20 - 1/12 of the effective fuel length at each of the upper and the lower ends of the fuel rod. Then, the concentration of the burnable poisons in a region above a boundary defined at a position 1/3 - 1/2, from beneath, of the effective fuel length is made smaller than that in the lower region. This enables to suppress excess reactions of fuels to reduce the mass of the burnable neutron. Excellent reactivity control performance at the initial stage of the burning can be attained. (T.M.)

Along with its positive attributes as an adsorbent of radioiodine in nuclear plant air cleaning systems, silver zeolite has the disadvantage of being susceptible to poisoning. (Poisoning is defined as the reduction of efficiency in radioiodine removal.) In view of the gravimetric and infrared spectroscopy data presented, π-bonded hydrocarbons, oxygenated organics, and halocarbons appear to be probable poisons of a silver zeolite filtration system

The use of dietary supplements has increased and is associated with adverse effects. Indications for use include recreation, body image concerns, mood enhancement, or control of medical conditions. The risk of adverse effects may be enhanced if agents are used improperly. The objective of this study was to determine the frequency of abuse and misuse of 4 dietary substances among adolescents reported nationally to poison centers. Secondary outcomes included an assessment of medical outcomes, clinical effects, location of treatments provided, and treatments administered. This descriptive retrospective review assessed data concerning the use of garcinia (Garcinia cambogia), guarana (Paullinia cupana), salvia (Salvia divinorum), and St John's wort (Hypericum perforatum) among adolescents reported nationally to poison centers from 2003 to 2014. Adolescents with a singlesubstance exposure to one of the substances of interest coded as intentional abuse or misuse were included. Poison center calls for drug information or those with unrelated clinical effects were excluded. Data were collected from the National Poison Data System. There were 84 cases: 7 cases of Garcinia cambogia, 28 Paullinia cupana, 23 Salvia divinorum, and 26 Hypericum perforatum. Garcinia cambogia was used more frequently by females (100% versus 0%), and Paullinia cupana and Salvia divinorum were used more frequently by males (61% versus 36% and 91% versus 9%, respectively). Abuse, driven by Salvia divinorum, was more common overall than misuse. Abuse was also more common among males than females (p <0.001). Use of these agents fluctuated over time. Overall, use trended down since 2010, except for Garcinia cambogia use. In 62 cases (73.8%), the medical outcome was minor or had no effect or was judged as nontoxic or minimally toxic. Clinical effects were most common with Paullinia cupana and Salvia divinorum. Treatment sites included emergency department (n = 33; 39.3%), non-healthcare facility (n = 24

Exploration Health Risks: Probabilistic Risk Assessment

Science.gov (United States)

Rhatigan, Jennifer; Charles, John; Hayes, Judith; Wren, Kiley

2006-01-01

Maintenance of human health on long-duration exploration missions is a primary challenge to mission designers. Indeed, human health risks are currently the largest risk contributors to the risks of evacuation or loss of the crew on long-duration International Space Station missions. We describe a quantitative assessment of the relative probabilities of occurrence of the individual risks to human safety and efficiency during space flight to augment qualitative assessments used in this field to date. Quantitative probabilistic risk assessments will allow program managers to focus resources on those human health risks most likely to occur with undesirable consequences. Truly quantitative assessments are common, even expected, in the engineering and actuarial spheres, but that capability is just emerging in some arenas of life sciences research, such as identifying and minimize the hazards to astronauts during future space exploration missions. Our expectation is that these results can be used to inform NASA mission design trade studies in the near future with the objective of preventing the higher among the human health risks. We identify and discuss statistical techniques to provide this risk quantification based on relevant sets of astronaut biomedical data from short and long duration space flights as well as relevant analog populations. We outline critical assumptions made in the calculations and discuss the rationale for these. Our efforts to date have focussed on quantifying the probabilities of medical risks that are qualitatively perceived as relatively high risks of radiation sickness, cardiac dysrhythmias, medically significant renal stone formation due to increased calcium mobilization, decompression sickness as a result of EVA (extravehicular activity), and bone fracture due to loss of bone mineral density. We present these quantitative probabilities in order-of-magnitude comparison format so that relative risk can be gauged. We address the effects of

Ciguatera fish poisoning: Incidence, health costs and risk perception on Moorea Island (Society archipelago, French Polynesia).

Ciguatera Fish Poisoning (CFP) is a non-bacterial seafood poisoning well characterized in the remote archipelagos of French Polynesia, yet poorly documented in the Society archipelago, most notably on Moorea, the second most populated island in French Polynesia, which counts a high proportion of fishermen fishing on a regular basis. To address this knowledge gap, a holistic study of the ciguatera issue was conducted on Moorea. First, ciguatera risk was analysed in terms of incidence rate, fish species most commonly involved and risk stratification in Moorea lagoon based on 2007-2013 epidemiological data. A mean incidence rate of 8 cases per 10,000 inhabitants for the study period and an average under-reporting rate of 54% were found. Taking into account hospitalization and medication fees, and loss of productive days, the health-related costs due to CFP were estimated to be USD $1613 and $749 for each reported and unreported case, respectively, with an overall cost of USD $241,847 for the study period. Comparison of the present status of CFP on Moorea with a risk map established in the late 1970's showed that the spatial distribution of the risk has stayed relatively stable in time, with the north shore of the island remaining the most prone to ciguatera. Evaluation of the current knowledge on CFP among different populations groups, i.e. fishermen, residents and visitors, was also conducted through direct and indirect interviews. About half of the fishermen interviewed were actually able to identify risky fishing areas. While, overall, the CFP risk perception in the fishing community of Moorea seemed accurate, although not scientifically complete, it was sufficient for the safe practice of their fishing activities. This may be due in part to adaptive responses adopted by 36% of the fishermen interviewed, such as the avoidance of either high-risk fishing sites or toxic species. At the residents and visitors' level, the study points out a striking lack of awareness

A Narrative Review of Acute Adult Poisoning in Iran

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.

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.

Vikram Singh Grewal

2017-01-01

Full Text Available Introduction: Food poisoning is an acute gastroenteritis caused by ingestion of food or drink contaminated with either living bacteria or their toxins or inorganic chemical substances and poisons derived from plants and animals, commonly occurring as explosive outbreaks. The authors investigated an outbreak of food poisoning reported from a working men's hostel in urban area of Pune, Maharashtra. Materials and Methods: A retrospective cohort study design was adopted to investigate the outbreak. Of the total 170 members, 68 had symptoms of food poisoning. Remaining 102 unexposed members were also interviewed as part of the study. Data for environmental and laboratory parameters were also collected. Results: The point source outbreak indicated cooked chicken as the source with a risk ratio of 3.34 (95% confidence interval: 2.02–5.54 and attributable fraction for chicken was 75.3%. As is the case with 70% of food poisoning outbreaks, laboratory confirmation of causative organism could not be established, due to lack of specimens. However, the clinicoepidemiological profile of the patients displays a median incubation period of 8 h (range 5–17 h, along with the clinical symptomatology of a self-limiting disease of diarrhea, abdominal cramps, and nausea; suggested the implicating organisms to be either Clostridium perfringens or Bacillus cereus. Conclusion: The defaulting environmental parameters of compromised sanitary conditions, inadequate storage in refrigerator, improper storage of raw food, and unsafe cooking practices were enhancing factors, which need to be mandatorily addressed in bulk cooking.

Aim: To evaluate the clinical features of zinc phosphide poisoning and to investigate whether outcome could be prognosticated based on abdominal radiography on presentation. Materials and methods: All zinc phosphide-poisoned patients who were referred to Loghman-Hakim Hospital between March 2011 and September 2013 were retrospectively reviewed. Data regarding patients' demographic characteristics, characteristics of the poisoning, abdominal radiography results, and patients' outcome were recorded. Results: In 102 patients, the most common presenting signs/symptoms were nausea and vomiting (60%). Four patients died and another seven had developed complications during their hospitalization (metabolic acidosis, liver abnormalities, or acute renal failure). Nineteen patients had radio-opaque abdominal radiographs, nine of whom had died or developed complications (p = 0.001). Plain abdominal radiography had a sensitivity and specificity of 81% and 89% in predicting the patients' death or further development of complications. The positive and negative predictive values were 47% and 97%, respectively. Conclusion: Plain abdominal radiography is a very good tool for prognostication in patients with zinc phosphide poisoning. Immediate abdominal radiography can help stratify patients into high- or low-risk groups and determine treatment strategies. - Highlights: • ZP poisoning may cause severe symptoms or death although less frequent compared to ALP. • ZP-poisoned patients may deteriorate within the first 72 hours post-ingestion. • Abdominal radiography is a good tool to predict death/complications in these patients

Aluminum-based spent nuclear fuel (Al-SNF) from foreign and domestic research reactors is being consolidated at the Savannah River Site (SRS) for ultimate disposal in the Mined Geologic Disposal System (MGDS). Most of the aluminum-based fuel material contains highly enriched uranium (HEU) (more than 20 percent 235U), which challenges the preclusion of criticality events for disposal periods exceeding 10,000 years. Recent criticality analyses have shown that the addition of neutron absorbing materials (poisons) is needed in waste packages containing DOE SNF canisters fully loaded with Al-SNF under flooded and degraded configurations to demonstrate compliance with the requirement that Keff less than 0.95. Compatibility of poison matrix materials and the Al-SNF, including their relative degradation rate and solubility, are important to maintain criticality control. An assessment of the viability of poison and matrix materials has been conducted, and an experimental corrosion program has been initiated to provide data on degradation rates of poison and matrix materials and Al-SNF materials under repository relevant vapor and aqueous environments. Initial testing includes Al6061, Type 316L stainless steel, and A516Gr55 in synthesized J-13 water vapor at 50 degrees C, 100 degrees C, and 200 degrees C and in condensate water vapor at 100 degrees C.

Benson, B E; Smith, C A; McKinney, P E; Litovitz, T L; Tandberg, W D

2001-01-01

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.

Ciguatera fish poisoning is common in tropical and sub-tropical areas and larger fish (> 10 kg) are more susceptible to toxin accumulation with age. Although the coastal climate of northern New South Wales is considered sub-tropical, prior to 2014 there has only been 1 documented outbreak of ciguatera fish poisoning from fish caught in the region. During February and March 2014, 2 outbreaks of ciguatera fish poisoning involved 4 and 9 individuals, respectively, both following consumption of Spanish mackerel from northern New South Wales coastal waters (Evans Head and Scotts Head). Affected individuals suffered a combination of gastrointestinal and neurological symptoms requiring hospital treatment. At least 1 individual was symptomatic up to 7 months later. Liquid chromatography-tandem mass spectrometry detected the compound Pacific ciguatoxin-1B at levels up to 1.0 µg kg(-1) in fish tissue from both outbreaks. During April 2015, another outbreak of ciguatera fish poisoning was reported in 4 individuals. The fish implicated in the outbreak was caught further south than the 2014 outbreaks (South West Rocks). Fish tissue was unavailable for analysis; however, symptoms were consistent with ciguatera fish poisoning. To our knowledge, these cases are the southernmost confirmed sources of ciguatera fish poisoning in Australia. Educational outreach to the fishing community, in particular recreational fishers was undertaken after the Evans Head outbreak. This highlighted the outbreak, species of fish involved and the range of symptoms associated with ciguatera fish poisoning. Further assessment of the potential for ciguatoxins to occur in previously unaffected locations need to be considered in terms of food safety.

The long-term goal of the Integrated Risk Assessment program (IRAP) is to estimate risks to workers, the public, organizations, and groups with reserved rights to Site access, the ecosystem, and natural resources to aid in managing environmental restoration and waste management at the Hanford Site. For each of these, information is needed about current risks, risks during cleanup, and endstate risks. The objective is three-fold: to determine if and when to remediate, and to what extent; to identify information unavailable but needed to make better cleanup decisions; to establish technology performance criteria for achieving desired cleanup levels; to understand costs and benefits of activities from a Site-wide perspective. The no-intervention risk, assessment is the initial evaluation of public health risks conducted under IRAP. The objective is to identify types of activities that the US Department of Energy (DOE) must accomplish for closure of the Hanford Site, defined as no further DOE intervention. There are two primary conclusions from the no-intervention risk assessment. First, some maintenance and operations activities at Hanford must be continued to protect the public from grave risks. However, when large Hanford expenditures are compared to cleanup progress, funds expended for maintenance and operations must be put in proper perspective. Second, stakeholder's emphasis on public risks at Hanford, as indicated by remediation priorities, are not in line with those estimated. The focus currently is on compliance with regulations, and on dealing with issues which are visible to stakeholders

To review the clinical features and laboratory investigations of ciguatera patients in Hong Kong between 2004 and 2007 in order to show the timely sampling of implicated fish from ciguatera victims and application of validated mouse bioassay for confirming suspected clinical cases of ciguatera. Diagnosis of the ciguatera victims was based on history of coral fish consumption and clinical presentations stated in official guidelines for clinical diagnosis of ciguatera fish poisoning in Hong Kong. Food remnants of coral fish samples were collected swiftly from ciguatera victims between 2004 and 2007 for ciguatoxins (CTXs) analysis. Major clinical symptoms in ciguatera patients included gastrointestinal and neurological effects including limb numbness and diarrhoea, which developed at 0.5 to 15 hours after consumption of fish. In most cases, neurological symptoms were more common than gastrointestinal symptoms. A broad range of attack rate (10%-100%) was observed in each ciguatera outbreak. Validated mouse bioassay on ether extracts of the food remnant samples confirmed that all were CTXs-positive (ciguatera cases. Consistency between clinical and laboratory analysis for ciguatera poisoning illustrates the application of laboratory mouse bioassay in a timely fashion for confirming ciguatera poisoning cases and implementing effective public health measures. With further improvement in laboratory techniques, features of ciguatera fish poisoning cases can be better defined. Further studies are needed to determine the risk of each class of CTXs (Pacific-, Indian- and Caribbean-CTXs) in Hong Kong.

Background Acute kidney injury (AKI) is common after severe paraquat poisoning and usually heralds a fatal outcome. The rapid large increases in serum creatinine (Cr) exceed that which can be explained by creatinine kinetics based on loss of glomerular filtration rate (GFR). Methods and Findings This prospective multi-centre study compared the kinetics of two surrogate markers of GFR, serum creatinine and serum cystatin C (CysC), following paraquat poisoning to understand and assess renal functional loss after paraquat poisoning. Sixty-six acute paraquat poisoning patients admitted to medical units of five hospitals were included. Relative changes in creatinine and CysC were monitored in serial blood and urine samples, and influences of non-renal factors were also studied. Results Forty-eight of 66 patients developed AKI (AKIN criteria), with 37 (56%) developing moderate to severe AKI (AKIN stage 2 or 3). The 37 patients showed rapid increases in creatinine of >100% within 24 hours, >200% within 48 hours and >300% by 72 hours and 17 of the 37 died. CysC concentration increased by 50% at 24 hours in the same 37 patients and then remained constant. The creatinine/CysC ratio increased 8 fold over 72 hours. There was a modest fall in urinary creatinine and serum/urine creatinine ratios and a moderate increase in urinary paraquat during first three days. Conclusion Loss of renal function contributes modestly to the large increases in creatinine following paraquat poisoning. The rapid rise in serum creatinine most probably represents increased production of creatine and creatinine to meet the energy demand following severe oxidative stress. Minor contributions include increased cyclisation of creatine to creatinine because of acidosis and competitive or non-competitive inhibition of creatinine secretion. Creatinine is not a good marker of renal functional loss after paraquat poisoning and renal injury should be evaluated using more specific biomarkers of renal injury

Hepatotoxic Seafood Poisoning (HSP Due to Microcystins: A Threat from the Ocean?

Directory of Open Access Journals (Sweden)

Evangelos Briasoulis

2013-08-01

Full Text Available Cyanobacterial blooms are a major and growing problem for freshwater ecosystems worldwide that increasingly concerns public health, with an average of 60% of blooms known to be toxic. The most studied cyanobacterial toxins belong to a family of cyclic heptapeptide hepatotoxins, called microcystins. The microcystins are stable hydrophilic cyclic heptapeptides with a potential to cause cell damage following cellular uptake via organic anion-transporting proteins (OATP. Their intracellular biologic effects presumably involve inhibition of catalytic subunits of protein phosphatases (PP1 and PP2A and glutathione depletion. The microcystins produced by cyanobacteria pose a serious problem to human health, if they contaminate drinking water or food. These toxins are collectively responsible for human fatalities, as well as continued and widespread poisoning of wild and domestic animals. Although intoxications of aquatic organisms by microcystins have been widely documented for freshwater ecosystems, such poisonings in marine environments have only occasionally been reported. Moreover, these poisonings have been attributed to freshwater cyanobacterial species invading seas of lower salinity (e.g., the Baltic or to the discharge of freshwater microcystins into the ocean. However, recent data suggest that microcystins are also being produced in the oceans by a number of cosmopolitan marine species, so that Hepatotoxic Seafood Poisoning (HSP is increasingly recognized as a major health risk that follows consumption of contaminated seafood.

Bad news about an old poison. A case of nicotine poisoning due to both ingestion and injection of the content of an electronic cigarette refill

Full Text Available There are increasing concerns about the escalating use of electronic cigarettes (e-cigarettes. In particular, smokers have been advised by important agencies such as the US Food and Drug Administration about the potential harm to the health of these products, being now considered as drug delivery devices. The leading issues supporting this statement include the repeated inhalation of propylene glycol that is used as a diluent in refills, accidental poisoning, as well as evidence that ecigarettes may promote continued smoking since their use may compromise quitting motivations. Some authors have minimized these risks, considering the potential advantages of these devices for public health. Here we describe the first case of nicotine poisoning due to both ingestion and intravenous injection of the content of an e-cigarette refill, incorrectly mixed with methadone, bottled in a generic vial.

Chronic copper poisoning in lambs

Energy Technology Data Exchange (ETDEWEB)

Ross, D B

1964-08-08

This communication presented evidence of the elevation of plasma GOT (glutamic oxaloacetic transaminase or aspartate transaminase) concentration during the development of copper toxicity in some experimental lambs, and also demonstrated that plasma GOT concentration can be used to assess the course of the disease during treatment. A group of Kerry Hill lambs were fed 1 1/2 lb per day of a proprietary concentrate containing 40 parts of copper per million on a dry-matter basis in addition to hay and water ad lib. Data was included for the plasma GOT concentrations of the lambs, bled weekly after weaning from pasture to this diet. There was some variation between the individual lambs, and in one there was no increase in plasma GOT by the 20th week when all the surviving lambs were slaughtered. The concentrations of copper found in the caudate lobe of the liver and in the kidney cortex post mortem were given. The overall findings showed that the liver gave a reliable indication of the copper status of an animal whereas the kidney cortex copper concentration was a better criterion for the diagnosis of copper poisoning and was in agreement with the results of Eden, Todd, and Grocey and Thompson. Observations demonstrated the benefits resulting from the early diagnosis of chronic copper poisoning in lambs, when treatment of affected animals may be commenced before the haemolytic crisis develops. Treatment included reducing the copper intake and dosing with ammonium molybdate and sodium sulfate, and the plasma GOT concentration may be used to assess the rate of recovery. 4 references, 3 tables.

The following paper is an informal summary of salient points made in the presentation entitled open-quotes An Integrated Risk Assessment Approach: Risk Assessment in the Programmatic Environmental Impact Statement (PEIS).close quotes. This presentation was given at the U.S. DOE Integrated Planning Workshop in Denver, Colorado on June 2, 1994. Integrated decision analysis is very important in environmental restoration and waste management in the evaluation of such things as land use planning, waste load forecasting, cost analyses, and technology development activities. Integrated risk assessment is an approach that addresses multiple components of risk, including: risks from surplus facilities as well as typical environmental restoration sites, risks to the public, risks to workers, ecological risk, risks before, during and after remediation activities, and others

Suspected lead poisoning in two captive cheetahs (Acinonyx jubatus jubatus in South Africa, in 2008 and 2013

Directory of Open Access Journals (Sweden)

Michelle A. North

2015-08-01

Full Text Available Whilst lead poisoning in raptors, scavenging birds and waterfowl is well studied and common knowledge, there is surprisingly little literature detailing the risk to mammalian scavengers and captive carnivores fed hunted meat. This case report describes the death of two captive cheetahs (Acinonyx jubatus jubatus following acute onset of nervous symptoms. Clinical signs included hyper-excitability, seizures, arched back, tail held abnormally high and hyper-salivation. Necropsy findings included bullets or a bullet in their stomachs. Kidney and liver lead levels from one cheetah (15.6 ppm and 17 ppm respectively were consistent with a diagnosis of lead poisoning; liver from the second cheetah was not available for testing. Both animals were routinely fed hunted antelope or game birds. This is the first report of oral lead poisoning in captive large carnivores, although these are unlikely to be the first cases. Without awareness of the risks of feeding hunted game, lead exposure will continue to be an underdiagnosed reality in the rehabilitation of endangered carnivores.

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

Assessment of cardiovascular risk.

LENUS (Irish Health Repository)

Cooney, Marie Therese

2010-10-01

Atherosclerotic cardiovascular disease (CVD) is the most common cause of death worldwide. Usually atherosclerosis is caused by the combined effects of multiple risk factors. For this reason, most guidelines on the prevention of CVD stress the assessment of total CVD risk. The most intensive risk factor modification can then be directed towards the individuals who will derive the greatest benefit. To assist the clinician in calculating the effects of these multiple interacting risk factors, a number of risk estimation systems have been developed. This review address several issues regarding total CVD risk assessment: Why should total CVD risk be assessed? What risk estimation systems are available? How well do these systems estimate risk? What are the advantages and disadvantages of the current systems? What are the current limitations of risk estimation systems and how can they be resolved? What new developments have occurred in CVD risk estimation?

Erbium: alternative poison? stabilisation additive? what future?

International Nuclear Information System (INIS)

Porta, J.; Asou, M.

2001-01-01

Erbium was proposed as alternative poison to gadolinium at a very early stage. The potential interest of this poison compared to gadolinium is that it presents a relatively low ( 167 Er) absorption cross section in the thermal range and a non-negligible resonance integral that lead to a relatively slow consumption kinetic rather adapted to long or even very long cycles. The poisoning mode adapted to this poison, homogeneous in low concentration (< 3 %), does not downgrade the power distribution, on the one hand, as the absorption is low and spatially homogeneous, and the thermal conductivity, on the other hand, as the addition in the fuel oxide is in low quantity. A review of knowledge acquired as regards Er, from the 1960's to now, is presented. (authors)

Acute Poisoning with Methadone (Dolphin (Review

2017-01-01

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.

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.

Many of the wastes from processing fissile materials contain metals which may serve as nuclear criticality poisons. It would be advantageous to the criticality evaluation of these wastes to demonstrate that the poisons remain with the fissile materials and to demonstrate an always safe poison-to-fissile ratio. The first task, demonstrating that the materials stay together, is the job of the chemist, the second, calculating an always safe ratio, is an object of this paper

2011-07-01

Organophosphate acetylcholine esterase inhibitor poisoning is a major health problem in children. We report an unusual cause of organophosphate acetylcholine esterase inhibitor poisoning. Two children were admitted to the pediatric intensive care unit due to organophosphate acetylcholine esterase inhibitor poisoning after exposure from a home-made shampoo that was used for the treatment of head lice. Owing to no obvious source of poisoning, the diagnosis of organophosphate acetylcholine esterase inhibitor poisoning in one of these patients was delayed. Both patients had an uneventful recovery. Organophosphate acetylcholine esterase inhibitor poisoning from home-made shampoo is possible. In cases where the mode of poisoning is unclear, direct questioning about the use of home-made shampoo is warranted, in these cases the skin and particularly the scalp should be rinsed thoroughly as soon as possible.

Mahdi Balali-Mood

2012-06-01

Full Text Available Organophosphorous compounds have been employed as pesticides and chemical warfare nerve agents. Toxicity of organophosphorous compounds is a result of excessive cholinergic stimulation through inhibition of acetyl cholinesterase. Clinical manifestations include cholinergic syndromes, central nervous system and cardiovascular disorders. Organophosphorous pesticide poisonings are common in developing worlds including Iran and Sri Lanka. Nerve agents were used during the Iraq-Iran war in 1983-1988 and in a terrorist attack in Japan in 1994-1995. Following decontamination, depending on the severity of intoxication the administration of atropine to counteract muscarinic over-stimulation, and an oxime to reactivate acetyl cholinesterase are indicated. Supportive and intensive care therapy including diazepam to control convulsions and mechanical respiration may be required. Recent investigations have revealed that intravenous infusion of sodium bicarbonate to produce mild to moderate alkalinization is effective. Gacyclidine; an antiglutamatergic compound, was also proved to be beneficial in conjunction with atropine, pralidoxime, and diazepam in nerve agent poisoning. Intravenous magnesium sulfate decreased hospitalization duration and improved outcomes in patients with organophosphorous poisoning. Bio-scavengers including fresh frozen plasma or albumin have recently been suggested as a useful therapy through clearing of free organophosphates. Hemofiltration and antioxidants are also suggested for organophosphorous poisoning. Recombinant bacterial phosphotriesterases and hydrolases that are able to transfer organophosphorous-degrading enzymes are very promising in delayed treatment of organophosphorous poisoning. Recently, encapsulation of drugs or enzymes in nanocarriers has also been proposed.

Vo, Kathy; Smollin, Craig

2015-06-01

Online social networking services such as Facebook provide a novel medium for the dissemination of public health information by poison control centers in the United States. We performed a cross-sectional study of poison control center Facebook pages to describe and assess the use of this medium. Facebook pages associated with poison control centers were identified during a continuous two-week period from December 24, 2012 to January 7, 2013. Data were extracted from each page, including affiliated poison control center; page duration, measured in years since registration; number of subscribers; number of postings by general toxicological category; and measures of user-generated activity including "likes", "shares", and comments per posting. Among the 56 US poison control centers, 39 Facebook pages were identified, of which 29 were currently active. The total number of active pages has increased by 140% from 2009 to 2013 (average of 25% per year). The total number of all subscribers to active pages was 11,211, ranging from 40 to 2,456 (mean 387, SD 523), equal to 0.006% of all Facebook users in the United States. The number of subscribers per page was associated with page duration, number of postings, and type of postings. The types of toxicological postings were public education (45%), self-promotion (28%), childhood safety (12%), drugs of abuse (8%), environmental poisonings (6%), and general overdoses (1%). Slightly over half of all poison control centers in the United States are supplementing their outreach and education efforts through Facebook. In general, the more active the poison control center on Facebook, the more page followers and follower engagement gained.

Full Text Available Background: There is no clear data on the adherence of emergency medical services (EMS paramedics and hospital staff rather than those working in poisoning centers to the guidelines for managing acutely poisoned patients in developing countries. Methods: During a 6-month period, all EMS-managed poisoned patients along with those initially managed in a non-poisoning center before being referred to a poisoning hospital in Tehran, Iran, were instructed. Then the indications for administrating the activated charcoal (AC as well as performing gastric lavage (GL and tracheal intubation were studied and compared to the recommended guidelines. Results: A total of 3347 cases, including 1859 males (55.6%, were evaluated. There were significant differences between expected and performed endotracheal intubations in both EMS and other medical centers (P-value = 0.002 and 0.001, respectively as well as the administration of GL and AC in other medical centers (P-values= 0.003 and 0.03, respectively. Conclusion: More extensive educational programs should be established to improve the preliminary management of poisoned patients performed by EMS paramedics and staff of hospitals other than poisoning centers.

The aim of this paper is the application of terahertz (THz) spectroscopy combined with chemometrics techniques to distinguish poisonous and non-poisonous herbs which both have a similar appearance. Spectra of one poisonous and two non-poisonous herbs (Gelsemium elegans, Lonicera japonica Thunb, and Ficus Hirta Vahl) were obtained in the range 0.2-1.4 THz by using a THz time-domain spectroscopy system. Principal component analysis (PCA) was used for feature extraction. The prediction accuracy of classification is between 97.78 to 100%. The results demonstrate an efficient and applicative method to distinguish poisonous herbs, and it may be implemented by using THz spectroscopy combined with chemometric algorithms.

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.
