The prismatic block version of the High Temperature Reactor (HTR) considered as a candidate Very High Temperature Reactor (VHTR)design may use burnable poison pins in locations at some corners of the fuel blocks (i.e., assembly equivalent structures). The presence of any highly absorbing materials, such as these burnable poisons, within fuel blocks for hexagonal geometry, graphite-moderated High Temperature Reactors (HTRs) causes a local inter-block flux depression that most nodal diffusion-based method have failed to properly model or otherwise represent. The location of these burnable poisons near vertices results in an asymmetry in the morphology of the assemblies (or blocks). Hencemore » the resulting inadequacy of traditional homogenization methods, as these “spread” the actually local effect of the burnable poisons throughout the assembly. Furthermore, the actual effect of the burnable poison is primarily local with influence in its immediate vicinity, which happens to include a small region within the same assembly as well as similar regions in the adjacent assemblies. Traditional homogenization methods miss this artifact entirely. This paper presents a novel method for treating the local effect of the burnable poison explicitly in the context of a modern nodal method.« less

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 solidmore » 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.« less

Burnable poisons are used in nuclear reactors to produce a more level distribution of power in the reactor core and to reduce to necessity for a large control system. An ideal burnable poison would burn at the same rate as the fuel. In this study, separation of neutron-absorbing isotopes was investigated in order to eliminate isotopes that remain as absorbers at the end of fuel life, thus reducing useful fuel life. The isotopes Gd-157, Dy-164, and Er-167 were found to have desirable properties. These isotopes were separated from naturally occurring elements by means of plasma separation to evaluate feasibility andmore » cost. It was found that pure Gd-157 could save approximately $6 million at the end of four years. However, the cost of separation, using the existing facility, made separation cost- ineffective. Using a magnet with three times the field strength is expected to reduce the cost by a factor of ten, making isotopically separated burnable poisons a favorable method of increasing fuel life in commercial reactors, in particular Generation-IV reactors. The project also investigated various burnable poison configurations, and studied incorporation of metallic burnable poisons into fuel cladding.« less

Burnable poisons are used in all modern nuclear reactors to permit higher loading of fuel without the necessity of an overly large control rod system. This not only permits a longer core life but can also be used to level the power distribution. Commercial nuclear reactors commonly use B{sub 4}C in separate non-fueled rods and more recently, zirconium boride coatings on the fuel pellets or gadolinium oxide mixed with the fuel. Although the advantages are great, there are problems with using these materials. Boron, which is an effective neutron absorber, transmutes to lithium and helium upon absorption of a neutron.more » Helium is insoluble and is eventually released to the interior of the fuel rod, where it produces an internal pressure. When sufficiently high, this pressure stress could cause separation of the cladding from the fuel, causing overly high centerline temperatures. Gadolinium has several very strongly absorbing isotopes, but not all have large cross sections and result in residual burnable poison reactivity worth at the end of the fuel life. Even if the amount of this residual absorber is small and the penalty in operation small, the cost of this penalty, even if only several days, can be very high. The objective of this investigation was to study the performance of single isotopes in order to reduce the residual negative reactivity left over at the end of the fuel cycle. Since the behavior of burnable poisons can be strongly influenced by their configuration, four forms for the absorbers were studied: homogeneously mixed with the fuel, mixed with only the outer one-third of the fuel pellet, coated on the perimeter of the fuel pellets, and alloyed with the cladding. In addition, the numbers of fuel rods containing burnable poison were chosen as 8, 16, 64, and 104. Other configurations were chosen for a few special cases. An enrichment of 4.5 wt% {sup 235}U was chosen for most cases for study in order to achieve a 4-year fuel cycle. A standard

The University of Florida (UF) is carrying out basic research on a new class of thermally stable boron containing materials which appear to have special properties that will greatly enhance the performance of Burnable Poison Rod Assemblies (BPRA) and also Spent Fuel Containers (SFC). This new material ('Carborane') has the special properties of containing a tailored amount of boron, an extremely high hydrogen content, and being extremely stable to high temperatures. 'Carborane' reduces the water displacement penalty by 59% by the hydrogen present in the 'Carborane'. In addition to increasing safety margins, a cost benefit of approximately $500,000 per two-yearmore » cycle is projected from reduced enrichments, resulting from the use of this burnable poison material, making it no longer necessary to offset the water displacement reactivity penalty. This research program is supported by a Department of Energy NEER grant. (authors)« less

2006-07-01

The design challenges of the fertile-free based fuel (FFF) can be addressed by careful and elaborate use of burnable poisons (BP). Practical fully FFF core design for PWR reactor has been reported in the past [1]. However, the burnable poison option used in the design resulted in significant end of cycle reactivity penalty due to incomplete BP depletion. Consequently, excessive Pu loading were required to maintain the target fuel cycle length, which in turn decreased the Pu burning efficiency. A systematic evaluation of commercially available BP materials in all configurations currently used in PWRs is the main objective of thismore » work. The BP materials considered are Boron, Gd, Er, and Hf. The BP geometries were based on Wet Annular Burnable Absorber (WABA), Integral Fuel Burnable Absorber (IFBA), and Homogeneous poison/fuel mixtures. Several most promising combinations of BP designs were selected for the full core 3D simulation. All major core performance parameters for the analyzed cases are very close to those of a standard PWR with conventional UO{sub 2} fuel including possibility of reactivity control, power peaking factors, and cycle length. The MTC of all FFF cores was found at the full power conditions at all times and very close to that of the UO{sub 2} core. The Doppler coefficient of the FFF cores is also negative but somewhat lower in magnitude compared to UO{sub 2} core. The soluble boron worth of the FFF cores was calculated to be lower than that of the UO{sub 2} core by about a factor of two, which still allows the core reactivity control with acceptable soluble boron concentrations. The main conclusion of this work is that judicial application of burnable poisons for fertile free fuel has a potential to produce a core design with performance characteristics close to those of the reference PWR core with conventional UO{sub 2} fuel.

In prismatic block High Temperature Reactors (HTR), highly absorbing material such a burnable poison (BP) cause local flux depressions and large gradients in the flux across the blocks which can be a challenge to capture accurately with traditional homogenization methods. The purpose of this paper is to quantify the error associated with spatial homogenization, spectral condensation and discretization and to highlight what is needed for improved neutronics treatments of burnable poisons for the prismatic HTR. A new triangular based mesh is designed to separate the BP regions from the fuel assembly. A set of packages including Serpent (Monte Carlo), Xuthosmore » (1storder Sn), Pronghorn (diffusion), INSTANT (Pn) and RattleSnake (2ndorder Sn) is used for this study. The results from the deterministic calculations show that the cross sections generated directly in Serpent are not sufficient to accurately reproduce the reference Monte Carlo solution in all cases. The BP treatment produces good results, but this is mainly due to error cancellation. However, the Super Cell (SC) approach yields cross sections that are consistent with cross sections prepared on an “exact” full core calculation. In addition, very good agreement exists between the various deterministic transport and diffusion codes in both eigenvalue and power distributions. Future research will focus on improving the cross sections and quantifying the error cancellation.« less

A conceptual design for a 50 MWe sodium cooled, U-Pu-Zr metallic fuelled, fast reactor core, which aims at a core lifetime of 30 years, has been performed [1]. As for the compensation for a large burn-up reactivity through 30 years, an axially movable reflector, which is located around the core, carries the major part of it and a burnable poison does the rest. This concept has achieved not only a long core lifetime but also a high discharged burn-up. On this study, a conceptual design for a small fast reactor loading U-Zr metallic fuelled core instead of U-Pu-Zr fuelled coremore » has been conducted, based on the original core arrangement of 4S reactor [2]. Within the range of this study including safety requirements, adopting the burnable poison would be effective to construct a core concept that achieves both a long lifetime and a high discharged burn-up.

The analysis was performed for an infinite lattice with a leakage in the form of buckling and (U-Np)N fuel with 20% uranium enrichment. The combination of {sup 7}Li as a coolant and {sup 6}Li as a burnable poison results in a favorable criticality behavior during burnup.

2010-05-18

In High Temperature Reactors, burnable absorbers are utilized to manage the excess reactivity at the early stage of the fuel cycle. In this study QUADRISO particles are proposed to manage the initial xcess reactivity of High Temperature Reactors. The QUADRISO concept synergistically couples the decrease of the burnable poison with the decrease of the fissile materials at the fuel particle level. This echanism is set up by introducing a burnable poison layer around the fuel kernel in ordinary TRISO particles or by mixing the burnable poison with any of the TRISO coated layers. At the beginning of life, the nitialmore » excess reactivity is small because some neutrons are absorbed in the burnable poison and they are prevented from entering the fuel kernel. At the end of life, when the absorber is almost depleted, ore eutrons stream into the fuel kernel of QUADRISO particles causing fission reactions. The mechanism has been applied to a prismatic High Temperature Reactor with europium or erbium burnable absorbers, showing a significant reduction in the initial excess reactivity of the core.« less

Control requirements for advanced pressurized water reactor designs must be met with heavy loadings of burnable poison rods, the required reactivity hold-down typically amounting to 30% or more in a poisoned subassembly. Two apparent choices for poisons are natural boron rods and natural gadolinium rods. Studied and analyzed is the effect of these two poisons on the hot-to-cold reactivity upswing. Compared with an upswing of 2.9% in a nonpoisoned assembly, the upswing in the gadolinium-poisoned assembly is 3.0%, and the upswing in the boron-poisoned assembly is 8.8%. Thus the hot-to-cold control penalty is almost nil for the choice of gadoliniummore » and is considerable for the choice of boron.« less

The principal focus of this work is on developing a practical tool for designing the minimum amount of burnable poisons (BPs) for a pressurized water reactor using a typical Three Mile Island Unit 1 2-yr cycle as the reference design. The results of this study are to be applied to future reload designs. A new method, the Modified Power Shape Forced Diffusion (MPSFD) method, is presented that initially computes the BP cross section to force the power distribution into a desired shape. The method employs a simple formula that expresses the BP cross section as a function of the differencemore » between the calculated radial power distributions (RPDs) and the limit set for the maximum RPD. This method places BPs into all fresh fuel assemblies (FAs) having an RPD greater than the limit. The MPSFD method then reduces the BP content by reducing the BPs in fresh FAs with the lowest RPDs. Finally, the minimum BP content is attained via a heuristic fine-tuning procedure.This new BP design program has been automated by incorporating the new MPSFD method in conjunction with the heuristic fine-tuning program. The program has automatically produced excellent results for the reference core, and has the potential to reduce fuel costs and save manpower.« less

Verification of commercial low enriched uranium light water reactor fuel takes place at the fuel fabrication facility as part of the overall international nuclear safeguards solution to the civilian use of nuclear technology. The fissile mass per unit length is determined nondestructively by active neutron coincidence counting using a neutron collar. A collar comprises four slabs of high density polyethylene that surround the assembly. Three of the slabs contain {sup 3}He filled proportional counters to detect time correlated fission neutrons induced by an AmLi source placed in the fourth slab. Historically, the response of a particular collar design to amore » particular fuel assembly type has been established by careful cross-calibration to experimental absolute calibrations. Traceability exists to sources and materials held at Los Alamos National Laboratory for over 35 years. This simple yet powerful approach has ensured consistency of application. Since the 1980's there has been a steady improvement in fuel performance. The trend has been to higher burn up. This requires the use of both higher initial enrichment and greater concentrations of burnable poisons. The original analytical relationships to correct for varying fuel composition are consequently being challenged because the experimental basis for them made use of fuels of lower enrichment and lower poison content than is in use today and is envisioned for use in the near term. Thus a reassessment of the correction factors is needed. Experimental reassessment is expensive and time consuming given the great variation between fuel assemblies in circulation. Fortunately current modeling methods enable relative response functions to be calculated with high accuracy. Hence modeling provides a more convenient and cost effective means to derive correction factors which are fit for purpose with confidence. In this work we use the Monte Carlo code MCNPX with neutron coincidence tallies to calculate the influence

To solve in-core fuel management optimization problem, GARCO-PSU (Genetic Algorithm Reactor Core Optimization - Pennsylvania State Univ.) is developed. This code is applicable for all types and geometry of PWR core structures with unlimited number of fuel assembly (FA) types in the inventory. For this reason an innovative genetic algorithm is developed with modifying the classical representation of the genotype. In-core fuel management heuristic rules are introduced into GARCO. The core re-load design optimization has two parts, loading pattern (LP) optimization and burnable poison (BP) placement optimization. These parts depend on each other, but it is difficult to solve themore » combined problem due to its large size. Separating the problem into two parts provides a practical way to solve the problem. However, the result of this method does not reflect the real optimal solution. GARCO-PSU achieves to solve LP optimization and BP placement optimization simultaneously in an efficient manner.

Parametric Study of the Effect of Burnable Poison Rods for PWR Burnup Credit

The Interim Staff Guidance on burnup credit (ISG-8) issued by the United States Nuclear Regulatory Commission's (U.S. NRC) Spent Fuel Project Office recommends restricting the use of burnup credit to assemblies that have not used burnable absorbers. This recommended restriction eliminates a large portion of the currently discharged spent fuel assemblies from cask loading, and thus severely limits the practical usefulness of burnup credit. In the absence of readily available information on burnable poison rod (BPR) design specifications and usage in U.S. pressurized-water-reactors (PWRs), and the subsequent reactivity effect of BPR exposure on discharged spent nuclear fuel (SNF), NRC staffmore » has indicated a need for additional information in these areas. In response, this report presents a parametric study of the effect of BPR exposure on the reactivity of SNF for various BPR designs, fuel enrichments, and exposure conditions, and documents BPR design specifications. Trends in the reactivity effects of BPRs are established with infinite pin-cell and assembly array calculations with the SCALE and HELIOS code packages, respectively. Subsequently, the reactivity effects of BPRs for typical initial enrichment and burnup combinations are quantified based on three-dimensional (3-D) KENO V.a Monte Carlo calculations with a realistic rail-type cask designed for burnup credit. The calculations demonstrate that the positive reactivity effect due to BPR exposure increases nearly linearly with burnup and is dependent on the number, poison loading, and design of the BPRs and the initial fuel enrichment. Expected typical reactivity increases, based on one-cycle BPR exposure, were found to be less than 1% {Delta}k. Based on the presented analysis, guidance is offered on an appropriate approach for calculating bounding SNF isotopic data for assemblies exposed to BPRs. Although the analyses do not address the issue of validation of depletion methods for assembly designs with

The objective of this study was to develop an unique methodology and a practical tool for designing burnable poison (BP) pattern for a given PWR core. Two techniques were studied in developing this tool. First, the deterministic technique called Modified Power Shape Forced Diffusion (MPSFD) method followed by a fine tuning algorithm, based on some heuristic rules, was developed to achieve this goal. Second, an efficient and a practical genetic algorithm (GA) tool was developed and applied successfully to Burnable Poisons (BPs) placement optimization problem for a reference Three Mile Island-1 (TMI-1) core. This thesis presents the step by step progress in developing such a tool. The developed deterministic method appeared to perform as expected. The GA technique produced excellent BP designs. It was discovered that the Beginning of Cycle (BOC) Kinf of a BP fuel assembly (FA) design is a good filter to eliminate invalid BP designs created during the optimization process. By eliminating all BP designs having BOC Kinf above a set limit, the computational time was greatly reduced since the evaluation process with reactor physics calculations for an invalid solution is canceled. Moreover, the GA was applied to develop the BP loading pattern to minimize the total Gadolinium (Gd) amount in the core together with the residual binding at End-of-Cycle (EOC) and to keep the maximum peak pin power during core depletion and Soluble boron concentration at BOC both less than their limit values. The number of UO2/Gd2O3 pins and Gd 2O3 concentrations for each fresh fuel location in the core are the decision variables and the total amount of the Gd in the core and maximum peak pin power during core depletion are in the fitness functions. The use of different fitness function definition and forcing the solution movement towards to desired region in the solution space accelerated the GA runs. Special emphasize is given to minimizing the residual binding to increase core lifetime as

An accurate and computationally efficient two or three-dimensional neutron diffusion model will be necessary for the development, safety parameters computation, and fuel cycle analysis of a prismatic Very High Temperature Reactor (VHTR) design under Next Generation Nuclear Plant Project (NGNP). For this purpose, an analytical nodal Green’s function solution for the transverse integrated neutron diffusion equation is developed in two and three-dimensional hexagonal geometry. This scheme is incorporated into HEXPEDITE, a code first developed by Fitzpatrick and Ougouag. HEXPEDITE neglects non-physical discontinuity terms that arise in the transverse leakage due to the transverse integration procedure application to hexagonal geometry andmore » cannot account for the effects of burnable poisons across nodal boundaries. The test code being developed for this document accounts for these terms by maintaining an inventory of neutrons by using the nodal balance equation as a constraint of the neutron flux equation. The method developed in this report is intended to restore neutron conservation and increase the accuracy of the code by adding these terms to the transverse integrated flux solution and applying the nodal Green’s function solution to the resulting equation to derive a semi-analytical solution.« less

Inert matrix fuels (IMF) with plutonium may play a significant role to dispose of stockpiles of separated plutonium from military or civilian origin. For reasons of reactivity control of such fuels, burnable poisons (BP) will have to be used. The impact of different possible BP candidates (B, Eu, Er and Gd) on the achievable burnup as well as on safety and non-proliferation aspects of IMF are analyzed. To this end, cell burnup calculations have been performed and burnup dependent reactivity coefficients (boron worth, fuel temperature and moderator void coefficient) were calculated. All BP candidates were analyzed for one initial BP concentration and a range of different initial plutonium-concentrations (0.4-1.0 g cm-3) for reactor-grade plutonium isotopic composition as well as for weapon-grade plutonium. For the two most promising BP candidates (Er and Gd), a range of different BP concentrations was investigated to study the impact of BP concentration on fuel burnup. A set of reference fuels was identified to compare the performance of uranium-fuels, MOX and IMF with respect to (1) the fraction of initial plutonium being burned, (2) the remaining absolute plutonium concentration in the spent fuel and (3) the shift in the isotopic composition of the remaining plutonium leading to differences in the heat and neutron rate produced. In the case of IMF, the remaining Pu in spent fuel is unattractive for a would be proliferator. This underlines the attractiveness of an IMF approach for disposal of Pu from a non-proliferation perspective.

Limestone represents the main raw material for ordinary Portland cement clinker production. In this study eight natural limestones from different geological environments were chosen to prepare raw meals for clinker manufacturing, aiming to define a parameter controlling the burnability. First, limestones were characterized by X-Ray Fluorescence, X-Ray Powder Diffraction and Optical Microscopy to assess their suitability for clinker production and their petrographic features. The average domains size and the microstrain of calcite were also determined by X-Ray Powder Diffraction line profile analysis. Then, each limestone was admixed with clay minerals to achieve the adequate chemical composition for clinker production. Raw meals were thermally threated at seven different temperatures, from 1000 to 1450 °C, to evaluate their behaviour on heating by ex situ X-Ray Powder Diffraction and to observe the final clinker morphology by Scanning Electron Microscopy. Results indicate the calcite microstrain is a reliable parameter to predict the burnability of the raw meals, in terms of calcium silicates growth and lime consumption. In particular, mixtures prepared starting from high-strained calcite exhibit a better burnability. Later, when the melt appears this correlation vanishes; however differences in the early burnability still reflect on the final clinker composition and texture.

CONFU-B assemblies are PWR assemblies containing standard Uranium fuel rods and TRU bearing inert material fuel rods and are designed to achieve net TRU destruction over a 4.5-year irradiation. These highly heterogeneous assemblies tend to exhibit large intra-assembly power peaking factors (IAPPF). Neutronic strategies to reduce IAPPF are developed. The IAPPF are calculated at the assembly level using CASMO4, and these are used to calculate the most restrictive thermal margin (the Minimum Departure from Nucleate Boiling Ratio, MDNBR) using a whole-core VIPRE-01 model. This paper examines two strategies to manage the thermal margin of a CONFU-B assembly while retaining themore » TRU destruction performance: use of neutron poisons and tailored enrichment schemes. Burnable poisons can be used to suppress BOL reactivity of fresh CONFU-B assemblies with only minor impact on MDNBR and TRU destruction performance. Tailored enrichment, along with the use of soluble boron, can achieve significant improvements in MDNBR, but at some cost to TRU destruction performance. (authors)« less

Based on the results of the reactor physics assessment, conversion of the Advanced Test Reactor (ATR) at the Idaho National Laboratory (INL) can be potentially accomplished in two ways, by either using U-10Mo monolithic or U-7Mo dispersion type plates in the ATR fuel element. Both designs, however, would require incorporation of the burnable absorber in several plates of the fuel element to compensate for the excess reactivity and to flatten the radial power profile. Several different types of burnable absorbers were considered initially, but only borated compounds, such as B4C, ZrB2 and Al-B alloys, were selected for testing primarily duemore » to the length of the ATR fuel cycle and fuel manufacturing constraints. To assess and compare irradiation performance of the U-Mo fuels with different burnable absorbers we have designed and manufactured 28 RERTR miniplates (20 fueled and 8 non-fueled) containing fore-mentioned borated compounds. These miniplates will be tested in the ATR as part of the RERTR-13 experiment, which is described in this paper. Detailed plate design, compositions and irradiations conditions are discussed.« less

Poison ivy, poison oak, and poison sumac are now classified in the genus Toxicodendron which is readily distinguished from Rhus. In the United States, there are two species of poison oak, Toxicodendron diversilobum (western poison oak) and Toxicodendron toxicarium (eastern poison oak). There are also two species of poison ivy, Toxicodendron rydbergii, a nonclimbing subshrub, and Toxicodendron radicans, which may be either a shrub or a climbing vine. There are nine subspecies of T. radicans, six of which are found in the United States. One species of poison sumac, Toxicodendron vernix, occurs in the United States. Distinguishing features of these plants and characteristics that separate Toxicodendron from Rhus are outlined in the text and illustrated in color plates.

To investigate the characteristics of acute poisonings caused by various poisons in Guangxi, China. A retrospective investigation was performed in 5859 cases of acute poisonings who were admitted to 63 hospitals in 11 cities, as well as 531 types of poisons involved. The poisons were categorized into 6 groups; each group of cases was stratified by the rural or urban settings, frequency of poisoning, and cause of poisoning to analyze the numbers of cases and constituent ratios. Most types of poisons (68.74%) belonged to drugs (217 types) and pesticides (148 types). Most cases of poisonings (61.63%) were caused by pesticides (n = 2547) and chemicals (n = 1064). Pesticides, poisons of plant origins, and poisons of animal origins were responsible for most of the cases in rural settings; 88.46%, 79.10%, and 66.74% of the cases of these poison categories happened in rural settings. Chemicals, drugs, and other poisons were responsible for most of the cases in urban settings; 70.20%, 61.74%, and 63.73% of the cases of these poison categories happened in urban settings. The numbers of cases in 5-year-poisoning groups were the highest in all categories of poisons, accounting for 85.24%, 88.57%, 55.16%, 70.79%, 68.36%, and 66.44%of cases of respective categories. Most cases of poisonings by chemicals, poisons of animal origin, and other poisons were accident-related (86.24%, 72.66%, and 46.71%of the poison categories). Most cases of poisonings by pesticides and drugs were suicide-related (59.39% and 33.52% of the poison categories). Most cases by poisons of plant origin were caused by accidental ingestion (70.36% of the poison category). Most of the acute poisonings in Guangxi area are caused by pesticides and chemicals; the most common causes of poisoning are accidents, accidental ingestion, and suicide. There are significant differences in the causes of acute poisonings between the urban and rural settings.

Scombroid fish poisoning: an overlooked marine food poisoning.

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

PubMed

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.

Can poison control data be used for pharmaceutical poisoning surveillance?

2011-05-01

To determine the association between the frequencies of pharmaceutical exposures reported to a poison control center (PCC) and those seen in the emergency department (ED). A statewide population-based retrospective comparison of frequencies of ED pharmaceutical poisonings with frequencies of pharmaceutical exposures reported to a regional PCC. ED poisonings, identified by International Classification of Diseases, Version 9 (ICD-9) codes, were grouped into substance categories. Using a reproducible algorithm facilitated by probabilistic linkage, codes from the PCC classification system were mapped into the same categories. A readily identifiable subset of PCC calls was selected for comparison. Correlations between frequencies of quarterly exposures by substance categories were calculated using Pearson correlation coefficients and partial correlation coefficients with adjustment for seasonality. PCC reported exposures correlated with ED poisonings in nine of 10 categories. Partial correlation coefficients (r(p)) indicated strong associations (r(p)>0.8) for three substance categories that underwent large changes in their incidences (opiates, benzodiazepines, and muscle relaxants). Six substance categories were moderately correlated (r(p)>0.6). One category, salicylates, showed no association. Limitations Imperfect overlap between ICD-9 and PCC codes may have led to miscategorization. Substances without changes in exposure frequency have inadequate variability to detect association using this method. PCC data are able to effectively identify trends in poisonings seen in EDs and may be useful as part of a pharmaceutical poisoning surveillance system. The authors developed an algorithm-driven technique for mapping American Association of Poison Control Centers codes to ICD-9 codes and identified a useful subset of poison control exposures for analysis.
Scombroid poisoning: a review.

PubMed

Hungerford, James M

2010-08-15

Scombroid poisoning, also called histamine fish poisoning, is an allergy-like form of food poisoning that continues to be a major problem in seafood safety. The exact role of histamine in scombroid poisoning is not straightforward. Deviations from the expected dose-response have led to the advancement of various possible mechanisms of toxicity, none of them proven. Histamine action levels are used in regulation until more is known about the mechanism of scombroid poisoning. Scombroid poisoning and histamine are correlated but complicated. Victims of scombroid poisoning respond well to antihistamines, and chemical analyses of fish implicated in scombroid poisoning generally reveal elevated levels of histamine. Scombroid poisoning is unique among the seafood toxins since it results from product mishandling rather than contamination from other trophic levels. Inadequate cooling following harvest promotes bacterial histamine production, and can result in outbreaks of scombroid poisoning. Fish with high levels of free histidine, the enzyme substrate converted to histamine by bacterial histidine decarboxylase, are those most often implicated in scombroid poisoning. Laboratory methods and screening methods for detecting histamine are available in abundance, but need to be compared and validated to harmonize testing. Successful field testing, including dockside or on-board testing needed to augment HACCP efforts will have to integrate rapid and simplified detection methods with simplified and rapid sampling and extraction. Otherwise, time-consuming sample preparation reduces the impact of gains in detection speed on the overall analysis time. Published by Elsevier Ltd.

Using Poison Center Exposure Calls to Predict Methadone Poisoning Deaths

PubMed Central

Dasgupta, Nabarun; Davis, Jonathan; Jonsson Funk, Michele; Dart, Richard

2012-01-01

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, R2 = 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. PMID:22829925

To review history, biology, and medical aspects associated with fish and shellfish poisoning. Current literature, various Web sites, and Halstead's Volume II of Poisonous and Venomous Marine Animals. Determined by author. Determined by author. Fish and shellfish poisoning occur through the natural event of the food chain. Fish and shellfish consume algae that contain toxin-producing dinoflagellates. As a result they become contaminated and the toxin is concentrated as it moves up the food chain. Fish and shellfish can tolerate high levels of toxins, thereby appearing healthy while posing a significant danger to man. The toxin cannot be detected by sight, smell, or taste and is not destroyed by cooking or freezing. Thus man becomes an unsuspecting victim. There are several types of poisoning that occur through fish and shellfish consumption. They are ciguatera and scombroid fish poisoning; and paralytic, diarrheic, neurotoxic, and amnesic shellfish poisoning. A different toxin produces each of these poisonings; however, sources and symptoms may be similar among these poisonings making them difficult to diagnose. These intoxications can vary in severity from mild to fatal depending on the type and amount of toxin ingested. Age and underlying illnesses may also contribute to the outcome of these poisonings. Though people are aware of health warnings and may think they are important, it is human nature to think that "this could not possibly happen to me". Therefore, they fail to make the necessary changes required to reduce the incidence of fish and shellfish poisoning.
Lithium Poisoning.

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 supratherapeutic drug concentrations to clinical toxicity such as confusion, ataxia, or seizures. Lithium poisoning has a low mortality rate; however, chronic lithium poisoning can require a prolonged hospital length of stay from impaired mobility and cognition and associated nosocomial complications. Persistent neurological deficits, in particular cerebellar, are described and the incidence and risk factors for its development are poorly understood, but it appears to be uncommon in uncomplicated acute poisoning. Lithium is readily dialyzable, and rationale support extracorporeal treatments to reduce the risk or the duration of toxicity in high-risk exposures. There is disagreement in the literature regarding factors that define patients most likely to benefit from treatments that enhance lithium elimination, including specific plasma lithium concentration thresholds. In the case of extracorporeal treatments, there are observational data in its favor, without evidence from randomized controlled trials (none have been performed), which may lead to conservative practices and

We evaluated the safety and efficacy of a 1:1 mixture of pentadecylcatechol (PDC) and heptadecylcatechol (HDC) diacetate in reducing hypersensitivity to poison ivy and poison oak. The study was double-blind, parallel, randomized, and placebo controlled. The 44 subjects receiving the active drug ingested a cumulative dose of 306.5 mg over a five-week period. Subsequently, 14 patients were continued on a maintenance phase, ingesting an additional 960 mg of drug. The PDC-HDC diacetate was well tolerated, with no significant side effects. Evaluation of efficacy compared poststudy and prestudy reactions to patch tests using urushiol in doses of 0.025, 0.05, 0.125, 0.25, and 0.5 micrograms applied to the forearm. The results indicated that the induction phase as well as the maintenance phase did not induce a statistically significant hyposensitivity to urushiol, and we were thus unable to decrease sensitivity to poison ivy and poison oak in humans using orally ingested PDC-HDC diacetate.

Poison ivy and poison oak are the most common causes of allergic contact dermatitis in North America. We investigated whether a new topical lotion containing 5% quaternium-18 bentonite prevents experimentally induced poison ivy and poison oak allergic contact dermatitis. A single-blind, paired comparison, randomized, multicenter investigation was used to evaluate the effectiveness and safety of quaternium-18 bentonite lotion in preventing experimentally induced poison ivy and poison oak allergic contact dermatitis in susceptible volunteers. One hour before both forearms were patch tested with urushiol, the allergenic resin from poison ivy and poison oak, 5% quaternium-18 bentonite lotion was applied on one forearm. The test patches were removed after 4 hours and the sites interpreted for reaction 2, 5, and 8 days later. The difference in reactions between treated and untreated patch test sites was statistically analyzed. Two hundred eleven subjects with a history of allergic contact dermatitis to poison ivy and poison oak were studied. One hundred forty-four subjects had positive reactions to urushiol. The test sites pretreated with quaternium-18 bentonite lotion had absent or significantly reduced reactions to the urushiol compared with untreated control sites (p < 0.0001) on all test days. When it occurred, the reaction consistently appeared later on treated than on control sites (p < 0.0001). One occurrence of mild, transient erythema at the application site was the only side effect from the quaternium-18 bentonite lotion. Quaternium-18 bentonite lotion was effective in preventing or diminishing experimentally produced poison ivy and poison oak allergic contact dermatitis.

Histamine poisoning (scombroid fish poisoning): an allergy-like intoxication.

PubMed

Taylor, S L; Stratton, J E; Nordlee, J A

1989-01-01

Histamine poisoning results from the consumption of foods, typically certain types of fish and cheeses, that contain unusually high levels of histamine. Spoiled fish of the families, Scombridae and Scomberesocidae (e.g. tuna, mackerel, bonito), are commonly implicated in incidents of histamine poisoning, which leads to the common usage of the term, "scombroid fish poisoning", to describe this illness. However, certain non-scombroid fish, most notably mahi-mahi, bluefish, and sardines, when spoiled are also commonly implicated in histamine poisoning. Also, on rare occasions, cheeses especially Swiss cheese, can be implicated in histamine poisoning. The symptoms of histamine poisoning generally resemble the symptoms encountered with IgE-mediated food allergies. The symptoms include nausea, vomiting, diarrhea, an oral burning sensation or peppery taste, hives, itching, red rash, and hypotension. The onset of the symptoms usually occurs within a few minutes after ingestion of the implicated food, and the duration of symptoms ranges from a few hours to 24 h. Antihistamines can be used effectively to treat this intoxication. Histamine is formed in foods by certain bacteria that are able to decarboxylate the amino acid, histidine. However, foods containing unusually high levels of histamine may not appear to be outwardly spoiled. Foods with histamine concentrations exceeding 50 mg per 100 g of food are generally considered to be hazardous. Histamine formation in fish can be prevented by proper handling and refrigerated storage while the control of histamine formation in cheese seems dependent on insuring that histamine-producing bacteria are not present in significant numbers in the raw milk.

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.

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.

The toxicity of a number of chemicals are discussed in relation to their effects on farm animals. Arsenic has been a common cause of accidental poisoning of animals because it often is used to kill insects, parasites, weeds and rodents. It may be acute or chronic, depending on the amount consumed. The common symptoms are loss of flesh; a bright-red coloration of the mucous membranes; digestive disturbance, irregular pulse, and depression. Livestock may be affected by excess amounts of fluorides. An excessive amount of F interferes with the normal calcification of the bones and teeth. Animals may get lead poisoningmore » by chewing or licking lead-painted objects, lead storage batteries, and discarded painting materials. Orchard sprays also contain lead compounds. Symptoms include inflammation of the mucous membranes, loss of appetite, diarrhea, grinding of teeth, and salivation. Lead may also affect the nervous system causing animals to walk in circles and run into objects because of blindness. Molybdenum poisoning may occur in animals that graze on forage plants containing excessive amounts of the element. Some of the symptoms of chronic molybdenum poisoning are profuse diarrhea, and general weakness. Nitrate poisoning may be produced by a number of plants and fertilizer. The symptoms include staggering gait, tremors, rapid breathing and marked dilation of pupils. Salt poisoning may occur from the excessive consumption of sodium chloride. Symptoms include hypersensitivity to touch, loss of appetite and loss of coordination. Selenium poisoning is caused by the ingestion of plants that have absorbed selenium from the soils. Symptoms include loss of hair and rough horns, long and deformed hoofs, and sloughing of hoofs.« less
EPIDEMIOLOGY OF ACCIDENTAL POISONING

PubMed Central

Bissell, D. M.; McInnes, Robert S.

1960-01-01

In San Jose, California, studies of cases of accidental poisoning showed that the greatest hazard was to children 1 through 3 years of age. Drugs accounted for half the cases, household products for another third, and insecticides and rodenticides and others for the remainder. Most often poison material was within easy reach of the children. An analysis of families in which an accident occurred indicated that accidental poisoning might happen to any family. Since there was little after-effect of poisoning in cases in which treatment was obtained promptly, education directed toward getting prompt treatment seems most advisable. Community agencies interested in poison control need to focus their attention on parents of pre-school children. PMID:13801023
Pick your poison: what's new in poison control for the preschooler.

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.

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.

Gadolinia, {sup 135}Xe, {sup 149}Sm, control rod, and soluble boron are five neutron poisons that may appear in light water reactor assemblies. Reliable neutron poison worth estimation is useful for evaluating core operating strategies, fuel cycle economics, and reactor safety design. Based on physical presence, neutron poisons can be divided into two categories: local poisons and global poisons. Gadolinia and control rod are local poisons, and {sup 135}Xe, {sup 149}Sm, and soluble boron are global poisons. The first-order perturbation method is commonly used to estimate nuclide worths in fuel assemblies. It is well known, however, that the first-order perturbation methodmore » was developed for small perturbations, such as the perturbation due to weak absorbers, and that neutron poisons are not weak absorbers. The authors have developed an improved method to replace the first-order perturbation method, which yields very poor results, for estimating local poison worths. It has also been shown that the first-order perturbation method seems adequate to estimate worths for global poisons caused by flux compensation.« less

Acute carbon monoxide (CO) poisoning is the most common cause of poisoning and poisoning-related death in the United States. It manifests as broad spectrum of symptoms ranging from mild headache, nausea, and fatigue to dizziness, syncope, coma, seizures resulting in cardiovascular collapse, respiratory failure, and death. Cardiovascular complications of CO poisoning has been well reported and include myocardial stunning, left ventricular dysfunction, pulmonary edema, and arrhythmias. Acute myocardial ischemia has also been reported from increased thrombogenicity due to CO poisoning. Myocardial toxicity from CO exposure is associated with increased short-term and long-term mortality. Carboxyhemoglobin (COHb) levels do not correlate well with the clinical severity of CO poisoning. Supplemental oxygen remains the cornerstone of therapy for CO poisoning. Hyperbaric oxygen therapy increases CO elimination and has been used with wide variability in patients with evidence of neurological and myocardial injury from CO poisoning, but its benefit in limiting or reversing cardiac injury is unknown. We present a comprehensive review of literature on cardiovascular manifestations of CO poisoning and propose a diagnostic algorithm for managing patients with CO poisoning.

Over the last decade, use of phenethylamines has become increasingly prevalent. This study aimed to describe typical aspects of phenethylamine poisoning in order to better inform patient care. Phenethylamine poisoning cases reported to the Poison Control Center of Angers, France, from January, 2007 to December, 2013 were examined. Clinical findings were examined in 105 patients, including phenethylamine used, symptoms and final outcome. Patients were predominantly male (80%), with mean age 26±8 years. MDMA (38%), amphetamine (18%) and methamphetamine (14%) were the most commonly reported. Synthetic cathinones (10%) and the 2C series (7%) were also found. Substances most commonly associated with phenethylamine poisoning were cannabis (27%), ethanol (20%) and cocaine (9%). The most frequently reported symptoms included anxiety and hallucinations (49%), mydriasis and headache (41%), tachycardia (40%) and hypertension (15%). Complications such as seizures (7%), cardiac arrest (5%), toxic myocarditis (1%) and hemorrhagic stroke (1%) were also observed. Of the cases, the Poison Severity Score was: null or low, 66%, moderate, 21%, severe or fatal, 13%. Of the patients, 77% received hospital care and 12.4% were admitted to an intensive care unit. Analytical confirmations were obtained for all severe cases. While 93% of patients recovered, there were 5 deaths and 2 patients presented with neurological sequelae. Phenethylamine poisonings may be severe in young and healthy individuals. Physicians, toxicologists and analysts should be aware of new phenethylamine consumption trends in order to inform management of patient care and to contribute to a more responsive drug policy.

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 < 6 years of age were involved in 43.1% of cases; 74.0% of calls were made by the public and 23.7% by physicians; 74.8% of exposures were unintentional and 9.1% intentional. Chemicals were involved in 35.8% of all cases (single and multiple substances), pharmaceuticals in 48.8%, bites and stings in 3.8%, and plants and mushrooms in 1.6%. Substances most frequently involved were analgesics, cleaning products and antimicrobials. Clinical severity was moderate/major in 3.4%. Substances most frequently involved in moderate/major exposures were corrosives, insecticides and 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.
What is the definition of a poisoning?

PubMed

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.

Childhood poisonings are common, placing a substantial burden on health services. Case-control studies have found inconsistent evidence about modifiable risk factors for poisonings among children aged 0-4 years. This study quantifies associations between poison prevention practices and medically attended poisonings in children aged 0-4 years. Multicentre case-control study conducted at hospitals, minor injury units and family practices from four study centres in England between 2010 and 2013. Participants comprised 567 children presenting with unintentional poisoning occurring at home and 2320 community control participants matched on age, sex, date of event and study centre. Parents/caregivers provided data on safety practices, safety equipment use, home hazards and potential confounders by means of self-completion questionnaires. Data were analysed using conditional logistic regression. Compared with community controls, parents of poisoned children were significantly more likely not to store medicines out of reach (adjusted OR (AOR) 1.59; 95% CI 1.21 to 2.09; population attributable fraction (PAF) 15%), not to store medicines safely (locked or out of reach (AOR 1.83; 95% CI 1.38 to 2.42; PAF 16%) and not to have put all medicines (AOR 2.11; 95% CI 1.54 to 2.90; PAF 20%) or household products (AOR 1.79, 95% CI 1.29 to 2.48; PAF 11%) away immediately after use. Not storing medicines out of reach or locked away and not putting medicines and household products away immediately after use increased the odds of secondary care attended poisonings in children aged 0-4 years. If associations are causal, implementing these poison prevention practices could each prevent between 11% and 20% of poisonings. Published by the BMJ Publishing Group Limited.

The purpose of this paper is to provide a solution to a decades old safeguards problem in the verification of the fissile concentration in fresh light water reactor (LWR) fuel assemblies. The problem is that the burnable poison (e.g. Gd 2O 3) addition to the fuel rods decreases the active neutron assay for the fuel assemblies.

The technique makes use of the 238U atoms in the fuel rods to self-interrogate themore » 235U mass. The innovation for the new approach is that the 238U spontaneous fission (SF) neutrons from the rods induces fission reactions (IF) in the 235U that are time correlated with the SF source neutrons. Thus, the coincidence gate counting rate benefits from both the nu-bar of the 238U SF (2.07) and the 235U IF (2.44) for a fraction of the IF reactions. Whereas, the 238U SF background has no time-correlation boost. The higher the detection efficiency, the higher the correlated boost because background neutron counts from the SF are being converted to signal doubles. This time-correlation in the IF signal increases signal/background ratio that provides a good precision for the net signal from the 235U mass.

2012-10-15

Black-spot poison ivy is an uncommon presentation of poison ivy (Toxicodendron) allergic contact dermatitis. A 78-year-old sought evaluation of a black spot present on her right hand amid pruritic vesicles. The presentation of a black spot on the skin in a clinical context suggesting poison ivy is indicative of black-spot poison ivy. Dermoscopy revealed a jagged, centrally homogeneous, dark brown lesion with a red rim. A skin sample was obtained and compared against a poison ivy standard using ultra-fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS). This finding confirmed the presence of multiple urushiol congeners in the skin sample. Black-spot poison ivy may be added to the list of diagnoses that show a specific dermoscopic pattern.
Scombroid Poisoning: A Practical Approach.

Guergué-Díaz de Cerio, O; Barrutia-Borque, A; Gardeazabal-García, J

2016-09-01

Scombroid poisoning is a common cause of food poisoning worldwide. It is caused by ingestion of oily fish contaminated with bacteria that trigger the formation of high concentrations of histamine. Scombroid poisoning manifests mainly as a skin complaint (flushing that spreads downward and/or an erythematous urticarial rash affecting the face and upper trunk). Although the clinical course is usually self-limiting and benign, vascular compromise, bronchospasm, and arrhythmias have been described. It is important to establish a differential diagnosis that includes conditions such as fish allergy. Oral antihistamines are the mainstay of treatment. Scombroid poisoning is best prevented by refrigerating fish properly. The practical review of scombroid poisoning provided here is intended for dermatologists. Copyright © 2016 AEDV.

[Acute poisonings in Poland during the period 1997-1999. An analysis of files from the Krakow Poison Information Center].

PubMed

Kotwica, Małgorzata; Rogaczewska, Anna

2002-01-01

This work analyses the 1997-1999 data received from Polish poison units at Gdańsk, Kraków, Lublin, Łódź, Poznań, Rzeszów, Tarnów, Sosnowiec, Warszawa, Wrocław on patients hospitalised there and patients treated at other hospitals but consulted by specialists of those centres. The analysis shows that drugs constituted the most frequent cause of the poisonings (over 45% all poisonings). Poisonings with: alcohols accounted for 17.6%, gases (primarily by carbon monoxide) for 5.3%, pesticides for 4.5%, substances of abuse for 4.1%, and with organic solvents for 4.0% total poisonings. Suicidal poisonings constituted about 36% total poisonings, accidental over 25%, poisonings resulting for street-drugs and alcohol abuse over 23%, chemical emergency or fire 1%, while occupational poisonings constituted only 0.9% total poisonings. In 1997-1999, the highest numbers of deaths were recorded after intake of: drugs (102), ethylene glycol (39), alcohols (49, including 16 after intake of methanol and 33 after intake of ethanol), pesticides (15 deaths).

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.

2015-01-01

Organophosphorus(OP) poisoning, in addition to its cholinergic manifestations shows metabolic derangements leading to hyperglycemia. Apart from inhibiting acetylcholinesterase it also induces oxidative stress to exhibit this manifestation. The present study aims to assess the glycemic status of OP poisoned patients and its association with various factors in OP poisoning like oxidative stress and dose of atropine. This is a prospective study which recruited 102 patients above 18 years of age with history of OP poisoning. They were categorized into 3 grades-mild, moderate and severe based on the Peradeniya Organophosphorus Poisining Scale. The routine biochemical parameters along with serum malondialdehyde (MDA) and cholinesterase were estimated in the study group. Hyperglycemia and glycosuria were observed, with majority cases of hyperglycemia (57%) noticed in the severe group. There was a rise in the random plasma glucose (RPG), serum malondialdehyde (MDA), total dose of atropine across the groups along with a fall in the serum cholinesterase with increase in severity of poisoning. The fall in plasma glucose at the time of discharge was significant in all three groups when compared to the admission random plasma glucose(RPG) level. This transient hyperglycemia exhibited a significant positive association with serum MDA and dose of atropine administered during treatment (p<0.05). Glycemic status in OP poisoning may play a role in identifying the severity of poisoning at the time of admission.

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.
Identification and treatment of poison ivy dermatitis.

Briant, D; Brouder, G

1983-01-01

Poison ivy dermatitis is an acute self-limiting problem of two or three weeks' duration that can cause significant discomfort. Poison ivy, poison oak and poison sumac cause more cases of allergic contact dermatitis than all the other contact allergens combined. Treatment of poison ivy dermatitis depends on the severity of the reaction. The nurse practitioner can manage the majority of poison ivy cases. However, if there is systemic involvement, a physician consultation is necessary. The patient can best be assisted by assessing the severity of the dermatitis, prescribing an appropriate supportive therapy and teaching preventive measures.
Circumstances of Accidental Poisoning in Childhood

PubMed Central

Jackson, R. H.; Walker, J. H.; Wynne, N. A.

1968-01-01

Of 377 children with accidental poisoning, the commonest ages were 1, 2, and 3. The most important contributory factor was that the poison was kept in an inappropriate place. Most containers were closed, but the children found them easy to open. In some cases the container itself was unsuitable for the contents. The frequency of poisoning in childhood might be reduced in six main ways: (1) a reduction in the quantity of drugs kept in the home; (2) the provision of drug cupboards; (3) the provision of containers that are difficult for children to open, or individually foil-wrapping tablets; (4) making tablets less attractive to children; (5) clear identification of potential poisons; and (6) increasing parental awareness of the circumstances under which poisoning occurs. A plea is made for further sociomedical research into the prevention of poisoning. PMID:5682329
Childhood self-poisoning: a one-year review.

2012-11-01

Self-poisoning in children is a serious health concern accounting for 2% and 5% of childhood deaths in the developed and developing world, respectively. Type of poison and intent varies between age groups, with alcohol poisoning becoming increasingly common in teenagers. The aim of the study was to identify the characteristics of paediatric self-poisoning at Ninewells Hospital, Dundee, as a function of age, sex, intent and type of poison. Data from patients under the age of 17 presenting to Ninewells Hospital's Emergency Department with self-poisoning from 1 December 2008 to 30 November 2009 inclusive were identified, classified and analysed using chi-square testing. Overall there was no significant difference in gender. However, females significantly dominated in the ≥12<17 years age group, with older females also significantly more likely to deliberately self-poison. Alcohol was the sole cause of accidental self-poisoning in this age group while paracetamol was used in the majority of cases of deliberate self-poisoning. In the <6 years age group, household chemical ingestion and over-the-counter medications were the most common poisons. The findings reflect previous published data and national trends. The prevalence of alcohol abuse in the ≥12<17 years age group is a major public health issue that must be addressed.

Exposure to toxic gases which can induce serious health effects, can occur in the working as well as in general environment, including home. The severity of gas poisoning is determined by its physical and chemical characteristics, intensity and duration of exposure, and concomitant diseases and injuries in the poisoned person. Manifestations of gas toxic action involve simple asphyxia, local irritation of respiratory mucosa, systemic toxicity, and a combination of these mechanisms. This article describes the characteristics, modes of exposure and health effects of most common gases causing poisoning at home. These include gas fuels, carbon monoxide, ammonia, chlorine, and fire gases such as nitrogen and sulphur oxides, hydrogen cyanide and phosgene. First aid as well as preventive measures to avoid exposure to toxic gases and prevent fire at home are also given. The Croatian Poison Control Centre gathered data on toxic gas exposures in households between November 2005 and July 2006. During this period 30 persons (3 % of the total number of cases) were exposed to toxic gases at home, including carbon monoxide, irritating vapours from cleaning agents and disinfectants, gas fuels, septic tank gases, tear-gas, and chlorofluorocarbons from refrigerators.
[Three cases of scombroid poisoning].

2018-01-01

Scombroid poisoning is a poorly known type of food poisoning due to the presence of histamine in spoiled fish of the Scombridae family. We report 3 cases of scombroid poisoning seen at the Fréjus-Saint-Raphaël hospital in the Var region. Within around thirty minutes of eating a meal containing tuna, three patients presented varied symptoms: malaise, itchy rash, headache, and for two of them, nausea. The diagnosis of scombroid poisoning was based on the circumstances in which the clinical signs appeared and on the signs themselves. The patients were given antihistamines and one injection of intravenous corticosteroids, and symptoms regressed rapidly within a few hours. The symptoms of scombroid poisoning appear within a few minutes after eating fish of the Scombridae family and related species. The first symptoms are cutaneous, with flush, pruritus, and erythema of the face and trunk having an urticarial appearance, together with faintness. Gastrointestinal symptoms include nausea, vomiting, abdominal cramps and occasionally diarrhea. Symptoms subside within a few hours. Histamine is present in the flesh of these fish due to decarboxylation of histidine through the action of Gram-negative bacteria whose development is enhanced by heat and sun. Scombroid poisoning is one of the most common types of poisoning caused by eating fish but it is underdiagnosed by dermatologists. The diagnosis is made by measuring histamine levels in the incriminated fish or in the patient's plasma. Copyright © 2017 Elsevier Masson SAS. All rights reserved.
Scombroid Poisoning

An outbreak of scombroid poisoning occurred in San Francisco in the fall of 1977. The vehicle was sashimi prepared from spoiled tuna fish. Prompt public health measures prevented further consumption of the implicated food. Laboratory studies showed the presence in the tuna of bacterial species capable of producing large amounts of histamine, a substance strongly implicated in scombroid poisoning. Chemical analysis showed that histamine is very unevenly distributed in the flesh of spoiling tuna, therefore accounting for the sometimes random occurrence of disease among people eating the same food at the same table.

1976-01-01

Poisoning occurring in animals caused by agents such as arsenic, lead, tin, and other necrotizing substances is often accompanied by a Clostridial septicemia. The toxins of the Clostridia involved bring about clinical signs and pathologic changes that differ considerably from those caused by the poisonous agent; thereby overshadowing those produced by the poison. The Clostridia involved most frequently are Clostridium septicum, sordelli, and novyi. Therapy in cases of poisoning by necrotizing substances should include measures to prevent possible Clostridial involvement.
The influence of petrography, mineralogy and chemistry on burnability and reactivity of quicklime produced in Twin Shaft Regenerative (TSR) kilns from Neoarchean limestone (Transvaal Supergroup, South Africa)

This study evaluates the influence of chemical, mineralogical and petrographic features of the Neoarchean limestone from the Ouplaas Mine (Griqualand West, South Africa) on its burnability and quicklime reactivity, considering the main use as raw material for high-grade lime production in twin shaft regenerative (TSR) kilns. This limestone consists of laminated clotted peloidal micrite and fenestrate microbial boundstone with herringbone calcite and organic carbon (kerogen) within stylolites. Diagenetic modifications include hypidiotopic dolomite, micrite to microsparite recrystallization, stylolites, poikilotopic calcite, chert and saddle dolomite replacements. Burning and technical tests widely attest that the Neoarchean limestone is sensitive to high temperature, showing an unusual and drastically pronounced sintering or overburning tendency. The slaking reactivity, according to EN 459-2 is high for lime burnt at 1050 °C, but rapidly decreases for lime burnt at 1150 °C. The predominant micritic microbial textures, coupled with the organic carbon, are key-factors influencing the low burnability and the high sintering tendency. The presence of burial cementation, especially poikilotopic calcite, seems to promote higher burnability, either in terms of starting calcination temperature, or in terms of higher carbonate dissociation rate. In fact, the highest calcination velocity determined by thermal analysis is consistent with the highest slaking reactivity of the lower stratum of the quarry, enriched in poikilotopic calcite. Secondly, locally concentered dolomitic marly limestones, and sporadic back shales negatively affects the quicklime reactivity, as well. This study confirms that a multidisciplinary analytical approach is essential for selecting the best raw mix for achieving the highest lime reactivity in TSR kilns.

2007-10-01

In September 1998, legislation was introduced in the United Kingdom to limit paracetamol pack sizes to 16 tablets of 500 mg at general sales outlets and 32 tablets of 500 mg at pharmacies. The effect of the regulations on severity of paracetamol poisoning is unclear. The aim of this study was to describe trends in the severity of paracetamol poisoning and to assess the impact of the 1998 Regulations on the enquiries to a UK poisons centre. We extracted data about the age, sex and number of tablets or capsules of paracetamol ingested by patients notified to Guy's and St Thomas' Poisons Unit (London, UK) between 1996 and 2004. During the study period, there were approximately 140 000 patients with suspected paracetamol poisoning, accounting for around 11% of all patients reported to the poisons unit. The median number of tablets fell from 25 to 20 for males and 20 to 16 for females after 1998. There was also a reduction in the proportion of patients who ingested 17-32 tablets (from 36% to 30%) and 33-100 tablets (from 25% to 19%). Following the 1998 Regulations there was a decline in the severity, but not frequency, of paracetamol poisoning cases reported to Guy's and St Thomas' Poisons Unit. It is unclear whether the decline in severity was a direct consequence of the regulations.
Common causes of poisoning: etiology, diagnosis and treatment.

2013-10-01

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.

The analysis of 1,026 reports of suspected pesticide poisonings to the regional Poison Control Centre at the Hospital for Sick Children, Toronto consisted of 597 (58.2%) cases less than six years of age. Age was the strongest predictor: there was a risk of 3.1 that young children would encounter rodenticide poisoning compared to that of insecticides; a ten-fold risk of having symptoms from pesticide poisoning if the victim was over five years of age; an increased risk of 5.9 of exposure to moderate or large amounts of pesticide, compared to small quantities, for those over five years of age; and there was less treatment referral for young children, and a 5.7 risk of being referred if the victim was over the age of five years. Other significant predictor variables include the type of person making the inquiry (lay or physician/nurse), the calendar season of the event, and the location (metropolitan or nonmetropolitan) of the event.

Savander, V. I.; Shumskiy, B. E., E-mail: borisshumskij@yandex.ru; Pinegin, A. A.

The possibility of decreasing the vapor fraction at the VVER-1200 fuel assembly outlet by shaping the axial power density field is considered. The power density field was shaped by axial redistribution of the concentration of the burnable gadolinium poison in the Gd-containing fuel rods. The mathematical modeling of the VVER-1200 core was performed using the NOSTRA computer code.

Acute allergic contact dermatitis due to poison ivy or poison oak is a common presenting complaint in the practices of many primary care physicians. While the clinical features are well described, reported treatment regimens vary in both topical and systemic therapies. We review herein the variability of presenting morphologic features of the disease and common treatment regimens, with attention given to complications of therapy. We also comment on the correct botanical designation, incidence, and immune mechanisms of the disease state and review measures to avoid allergic contact dermatitis due to poison ivy and poison oak.

Summer has its own special poisoning hazards for the vacationer, gardener or outdoorsman. Because of the comparative variety of accidental human poisonings from contact with these seasonal toxic substances, either artificial or natural, many family physicians are unfamiliar with their effects. Some of us, unfortunately, will be called upon to deal with them over the next few months. This article highlights some of the hazards, outlines their toxicology and summarizes the treatment of the poisoned patient. PMID:20468771

Information on childhood poisonings in Cyprus is limited. Our objective was to examine the epidemiology of poisonings among children in Cyprus. All children up to 15 years of age admitted for poisoning to the Archbishop Makarios Hospital in Nicosia, Cyprus between 2005 and 2008 were included in our study. All hospital poisoning records were reviewed. A total of 257 children were admitted for poisoning. The mean age of children was 3.1 years, of which 83.7% were below the age of 5 years old, while 53% were boys. The poisoning hospitalizations accounted for about 3% of all admissions to the pediatric department during the study period (4 years). The annual cumulative incidence of childhood poisoning hospitalizations was 116 per 100,000 children. Medications accounted for 46.1% of all poisonings, the most frequent cause being paracetamol (9.8%), cardiovascular medications (5.3%), antitussive medications (4.5%), and other painkillers (4.1%). Another 37.6% of hospitalizations involved household products such as household cleaning products (11.8%), petroleum products (11.0%), and rodenticides (5.7%). Among children who ingested petroleum distillates, 55.6% developed clinical symptomatology. The vast majority of cases were accidental (93.8%). Suicidal cases involved children 8-14 years old, mainly girls, and the most frequent poisoning ingested was paracetamol (46.7%). Poisoning hospitalizations represent an important cause of morbidity among children in Cyprus. Preventive strategies should include the education of caregivers on the handling of medications and household products as well as legislation requiring child-resistant packaging for all medications and household products including petroleum distillates.

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.

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.

Weaver, Lindell K; Deru, Kayla

2007-07-01

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.

The purpose of this current investigation was to describe the distribution characteristics of pesticides poisoning in Hangzhou during 2006-2013. The registration data of pesticide poisoning in Hangzhou during 2006-2013 were collected from health disserve surveillance information system which was part of China information system for disease control and prevention. The statistical analysis method included Pearson Chi-square test and Cochran-Armitage trend test. There were totally 6232 cases with pesticide poisoning during 2006-2013, of which 414 cases died. The fatality rate of poisoning patients was 6.64%. The pesticides, especially organophosphorus pesticides, were the main poison that caused poisoning, and patients with pesticide poisoning accounted for 80.60% of all the poisoning patient. There was more female patients than male patients among non-productive pesticide poisoning, but on the contrary among productive pesticide poisoning. The incidence of pesticides poisoning had significant increase in the third season. Occupational pesticide poisoning and non-occupational pesticide poisoning had the different distribution character. Non-occupational pesticide poisoning was the chief reason of pesticide poisoning. The pesticides, especially organophosphorus pesticides, were the main poisons threatening the health of people in Hangzhou, and the effective prevention and control measures should be taken immediately.

This study has been carried out to assess the health damages due to pesticide use and its related risk factors among Korean farmers. Data regarding pesticide handling and poisoning symptoms were collected by means of a questionnaire filled in by 1,032 farmers from two provinces. The results showed that during summer farming 21.9% of the subjects experienced suspected pesticide poisoning. 18.8% mild poisoning, and 2% more serious poisoning. Univariate and logistic regression analyses between "no poisoning", including the "suspected poisoning" and "poisoning" groups, were performed to select significant variables related to pesticide poisoning. Four variables were significantly associated: sex, days of consecutive pesticide use, hours of pesticide use per day, having received safety education (weakly associated), and compliance with safety guidelines for application. Safety education was weakly associated with poisoning, while age, education, wearing protective gear, and compliance with safety guidelines for personal hygiene after pesticide use were not significant risk factors to determine pesticide poisoning.

Common Travel Medicine sources generally do not provide information on the risk of methanol poisoning among travellers who visit Indonesia. The aim of this analysis was to increase knowledge on this topic through reports from bibliographic databases and Internet sources. Case reports and studies on methanol poisoning in Indonesia were retrieved through PubMed, Embase and Google Scholar database searching. The Google search was used to retrieve the Web Media articles reporting fatal and non-fatal methanol poisoning in Indonesia, in a timeframe from 01.01.2009 to 03.03.2013. Three case reports of methanol poisoning involving four travellers to Indonesia were found in bibliographic databases. The media sources searching identified 14 articles published online, reporting 22 cases of methanol poisoning among travellers after consumption of local alcohol beverages. The total number of death cases was 18. Some sources report also a large number of cases among the local population. Methanol poisoning is likely to be an emerging public health problem in Indonesia, with an associated morbidity and mortality among travellers and local people. Some strategies can be implemented to prevent or reduce harm among travellers. Copyright © 2013 Elsevier Ltd. All rights reserved.

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.

Since ancient times poisoning has been treated medicinally. Clinical toxicology, in the narrow sense of the term, developed from the foundation of specialized medical treatment units for poisoning and the formation of the first poison information centers in the second half of the twentieth century. Historically, the first poison information centers were often localized at pediatric clinics or departments of internal medicine. It became increasingly more obvious that this pooling of competences made sense. This article gives a general introduction in clinical toxicology and presents the functions and key activities of emergency poison centers. The organisation and work of a poisons centre is demonstrated on the basis of the Poisons Information Center (GIZ) North annual report for 2011. In a short summary the basic principles of clinical toxicology are elucidated: the primary removal of poisons by gastric lavage and administration of activated charcoal, secondary removal of poisons by enhanced elimination using hemodialysis, hemoperfusion, multi-dose activated charcoal and molecular adsorbent recirculating systems (MARS) and the indications for administration of specific antidotes or antivenins (antisera against poisoning by poisonous animals). Gastric lavage is indicated within 1 h after ingestion of a potentially life-threatening dose of a poison. In cases of poisoning with substances which penetrate the central nervous system (CNS) gastric lavage should be performed only after endotracheal intubation due to the risk of aspiration. The basic management of poisoned patients by emergency medicine personnel out of hospital and on the way to hospital is presented. The Bremen list, a compilation of the five antidotes, atropine, 4-dimethylaminophenol (4-DMAP), tolonium chloride, naloxone and activated charcoal for out of hospital treatment by emergency doctors is presented. In all, even questionable cases of poisoning consultation at emergency poison centers is

Methanol poisoning has become a considerable problem in Iran. Liver can show some features of poisoning after methanol ingestion. Therefore, our concern was to examine liver tissue histopathology in fatal methanol poisoning cases in Iranian population. In this study, 44 cases of fatal methanol poisoning were identified in a year. The histological changes of the liver were reviewed. The most striking features of liver damage by light microscopy were micro-vesicular steatosis, macro-vesicular steatosis, focal hepatocyte necrosis, mild intra-hepatocyte bile stasis, feathery degeneration and hydropic degeneration. Blood and vitreous humor methanol concentrations were examined to confirm the proposed history of methanol poisoning. The majority of cases were men (86.36%). In conclusion, methanol poisoning can cause histological changes in liver tissues. Most importantly in cases with mean blood and vitreous humor methanol levels greater than 127 ± 38.9 mg/dL more than one pathologic features were detected.

There is a rising trend of fatal poisonings due to medicinal opioids in several countries. The present study evaluates the drug and alcohol findings as well as the cause and manner of death in opioid-related post-mortem cases in Finland from 2000 to 2008. During this period, fatal poisonings by prescription opioids (buprenorphine, codeine, dextropropoxyphene, fentanyl, methadone, oxycodone, tramadol) increased as a share of all drug poisonings from 9.5% to 32.4%, being 22.3% over the whole period. A detailed study including the most prevalent opioids was carried out for the age group of 14-44 years, which is the most susceptible age for drug abuse in Finland. Poisonings by the weak opioids, codeine and tramadol, were found to be associated with large, often suicidal overdoses resulting in high drug concentrations in blood. Methadone poisonings were associated with accidental overdoses with the drug concentration in blood remaining within a therapeutic range. The manner of death was accidental in 43%, 55% and 94% of cases in codeine, tramadol and methadone poisonings, respectively. The median concentration of codeine and the median codeine/morphine concentration ratio were higher in codeine poisonings (1.4 and 22.5 mg/l, respectively) than in other causes of death (0.09 and 5.9 mg/l, respectively). The median concentrations of tramadol and O-desmethyltramadol were higher in tramadol poisonings (5.3 and 0.8 mg/l, respectively) than in other causes of death (0.6 and 0.2 mg/l, respectively). In methadone poisonings, the median concentration of methadone (0.35 mg/l) was not different from that in other causes of death (0.30 mg/l). Sedative drugs and/or alcohol were very frequently found in fatal poisonings involving these prescription opioids. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

The clinical features of 12 children who incurred non-accidental salt poisoning are reported. The children usually presented to hospital in the first six months of life with unexplained hypernatraemia and associated illness. Most of the children suffered repetitive poisoning before detection. The perpetrator was believed to the mother for 10 children, the father for one, and either parent for one. Four children had serum sodium concentrations above 200 mmol/l. Seven children had incurred other fabricated illness, drug ingestion, physical abuse, or failure to thrive/neglect. Two children died; the other 10 remained healthy in alternative care. Features are described that should lead to earlier detection of salt poisoning; the importance of checking urine sodium excretion, whenever hypernatraemia occurs, is stressed. PMID:8503665

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.

The aim of this study was to explore the epidemiologic characteristics of unintentional poisoning cases and the factors associated with inpatient mortality. Data were retrieved from the National Health Insurance database from 2005 to 2007. Patients with diagnosis classifications of ICD-9-CM E850-E869 (unintentional poisoning) were selected. SPSS 18.0 software was used for the analysis. In Taiwan between 2005 and 2007, a total of 11,523 patients were hospitalised due to unintentional poisoning, with a hospitalisation rate of 16.83 per 100,000, of which 60.1% and 39.9% were attributable to drug poisoning and solid, liquid and gas substance poisoning, respectively. The hospitalisation rate in men was higher than that of women. The age group of 45-64 had the highest hospitalisation rate of 52.85 per 100,000. The inpatient mortality rate increased with the presence of the following factors: age of 65 or older, surgery or procedure, a higher Charlson Comorbidity Index (CCI), short length of hospital stays, acute respiratory failure, alcohol poisoning, pesticide poisoning and a higher-level hospital visited. Methanol, herbicides and organophosphorus pesticide intoxications are associated with higher mortality rates. Therefore, when caring for patients poisoned by the above agents, healthcare professionals should look out for their clinical development to ensure quality of care and to reduce mortality.

Lithium is an effective drug in the treatment of bipolar disorder and other psychiatric and neurological diseases. Unfortunately, its therapeutic index is narrow. There are three types of lithium poisoning: acute poisoning (in untreated patients), acute on chronic poisoning, when an overdose is taken accidentally or with suicidal intent, in patients under treatment and chronic poisoning (patient treated with lithium) when drug intake is correct but excessive in relation to its elimination (increased dose or more often reduced clearance) resulting in lithium overload. In this last condition, the clinical presentation is primary neurological while therapy involves the nephrologist provided that lithium clearance is mainly renal and hemodialysis is the most effective method for removal.

Carbon monoxide poisoning from portable electric generators.

Hampson, Neil B; Zmaeff, Jennette L

2005-01-01

While the overall death rate from unintentional carbon monoxide (CO) poisoning has decreased in the United States due to improved automobile emissions controls and a decline in CO poisonings from motor vehicles, exposures have not changed from some sources of CO. One of these is the operation of portable electrical generators in poorly ventilated spaces. This study sought to describe the population poisoned from CO produced by portable electric generators, and to determine the reasons that generators are operated in a hazardous fashion. Cases of CO poisoning referred for treatment with hyperbaric oxygen at Virginia Mason Medical Center in Seattle from November 1978 to March 2004 were reviewed. Those cases that resulted from portable generator use were selected for analysis. Sixty-three patients aged 2 to 85 years were treated for CO poisoning from portable electric generators. They included 34 males and 29 females who were poisoned in 37 separate incidents. Thirty-four lost consciousness with the exposure. Of the 63 total patients, 60 spoke English. Generators were typically used when normal electrical service was disrupted by a storm or in remote locations. In 29 of 37 incidents, the generator was operated in the home environment, most commonly in the garage. Lack of awareness of the dangers of CO poisoning or lack of knowledge of ventilation requirements were the most commonly identified reasons. CO poisoning from portable electric generators occurs in a characteristic population, in a few typical locations and for a limited number of reasons. This information may help target prevention efforts for this form of poisoning, such as warning labels or educational programs.

By comparing our data for the period 1985-2008 with findings from a previous report covering the period 1975-1984, we aimed to share our experience with poisoning cases in order to contribute toward its prevention, diagnosis and treatment. The records of patients admitted to the Pediatric Intensive Care Unit with acute poisoning between November 1985 and October 2008 were evaluated retrospectively. The records of 2251 patients with acute poisoning could be retrieved. Poisoning mostly occurred in the home (92%), via the oral route (92.5%) and by a single intoxicant (81.3%). Two distinct peaks were observed: in boys between 1-5 years of age and in girls between 13-16 years of age. It was noted that 67.4% of poisoning cases were accidental, whereas 25.9% were suicidal and 6.7% were a result of a therapeutic error. Nearly two-thirds (64%) of cases were drug-related, while 36% were non-drug-related. Analgesics-antipyretics ranked first among the drug-related cases, whereas ingestion of a corrosive substance was most common among cases with non-drug poisoning. Colchicine was associated with the highest fatality, while among the causes of non-drug poisoning, carbon monoxide was the deadliest. The overall mortality rate in this study was 1.9%. Mortality from non-drug poisoning was higher than from drug-related causes (3.9% vs. 1.3%). Almost all cases of poisoning below the age of 6 years are potentially preventable. The results of this study highlight the need for reforms in industrial and health policies, with the aim of increasing awareness regarding potential toxins, appropriate storage of potential toxins, and general precautions to promote safety in the home.

Acute poisoning is frequently encountered at emergency department. This study was to investigate the epidemiology and characteristics of patients with acute poisoning who were treated at the Emergency Center, Fujian Provincial Hospital, China. We retrospectively analyzed the gender, age, causes of poisoning, types of poisons, poisoning route, emergency diagnoses, outcomes, and prognoses of these patients. Altogether 2867 patients with acute poisoning were treated from January 2004 to December 2009. The ratio of male to female was 1:1.04, and their average age was 33.8 years. Of the 2867 patients, 76.39% were between 18 and 40 years old. The incidence of acute poisoning was as high as 11.33% in January each year. The incidence of poisoning was in a descending order: alcohol poisoning (54.55%), medication poisoning (25.95%), pesticide poisoning (5.65%), and drug poisoning (4.88%). Most (56.44%) of the patients with drug poisoning were under 25 years and their mean age was significantly lower than that of patients with medication poisoning or alcohol poisoning (P < 0.01). Approximately 69.54% of the patients were followed up after emergency treatment, 30.39% were hospitalized, and four patients died. Acute poisoning is largely alcohol poisoning and medication poisoning in a city. The emergency green channel "pre-hospital emergency care-emergency department-hospital treatment" can significantly improve the survival rate of patients with acute poisoning.
Interpersonal problem-solving deficits in self-poisoning patients.

Self-poisoning patients (n = 40) were compared with psychiatric patients (n = 40) and nonpatient controls (n = 20) on measures of interpersonal problem-solving skills and locus of control in an effort to determine the importance of these cognitive and personality variables in self-poisoning behavior. The psychiatric and self-poisoning groups showed deficits on measures assessing interpersonal problem solving when compared with nonpatient controls. The self-poisoning group performed below the level of the psychiatric patients on all except one test, on which they performed at the level of the psychiatric group. Locus of control did not differentiate self-poisoning patients from nonpatient controls, and it was concluded that this variable is not an important factor in self-poisoning behavior.

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

The aim of this research was to study the role and trend of antidepressant use as a method of suicide in completed self-poisoning suicides in patients with affective disorders during a 23-year follow up period. The data consisted of 483 completed self-poisoning suicides from 1988 to 2011 in the province of Oulu in Northern Finland (286 men and 197 women). Of the self-poisoning victims, 26.9% (n=130) had hospital-treated unipolar depression and 3.1% (n=15) hospital-treated bipolar disorder. Further, 53.8% (n=70) of those with unipolar depression and 53.3% (n=8) of those with bipolar depression died by suicide using antidepressants. During the 23-year follow-up period, the proportion of those using antidepressants doubled among all self-poisoning victims of suicide. A significant decline was observed in the use of tricyclic antidepressants in self- poisoning suicides while a linear increase was found in the use of SSRIs (selective serotonin reuptake inhibitors) and other antidepressants. During recent years one in five self-poisoning suicides involved the use of antiepileptics. A limitation of our study was that the psychiatric diagnoses only include hospital inpatient episodes. In conclusion, the use of new antidepressants has increased rapidly, but the risk of their use in self-poisoning suicide has perhaps been underestimated. Copyright © 2017 Elsevier Ireland Ltd.

To provide scientific evidence of making measures for prevention of pesticide poisoning, the investigation on the condition of pesticide poisoning was carried out in Quzhou. Registration data of pesticide poisoning from 2008 to 2010 in Quzhou were collected and statistically analyzed by SPSS 12.0. During the three years, there were 1222 cases reported for pesticide poisoning. Among them, the number of occupational poisoning was 225 (1 case died), with fatality rate of 0.44%. The number of non-occupational poisoning was 997 (77 cases died), and its fatality rate was 7.72% . The incidence of occupational poisoning and non-occupational poisoning accounted for 18.4% and 81.6% respectively. Male patients were in the majority in occupational pesticides poisoning (accounting for 76.4%), female patients in non-occupational poisoning (accounting for 52.1%). The pesticide poisoning mainly occurred from July to September. Occupational poisoning and non-occupational poisoning cases mainly concentrated in over 65 age group, accounting for 36.0% (81 cases) and 26.3% (262 cases) respectively. Insecticide ranks the first in the terms of total poisoning cases caused by pesticide, and organophosphate poisoning ranks the first in all insecticides. Pesticides poisoning has badly threatened the public health in Quzhou, attention should be paid to non-occupational poisoning. The pesticides poisoning was mainly caused by organophosphate insecticides.
Lead poisoning in six captive avian species

Red-winged blackbirds (Agelaius phoeniceus), brown-headed cowbirds (Molothrus ater), common grackles (Quiscalus quiscula), mallards (Anas platyrhynchos), northern bobwhites (Colinus virginianus), and eastern screech-owls (Otus asio) were poisoned with a concentration of lead (Pb) acetate in the diet which was increased by 60% each week until half of the birds in each treatment group died; surviving birds and all control birds except screech-owis were then killed by euthanasia. An additional group of mallards was poisoned with Pb shot. The gizzards of mallards poisoned either way usually were stained with bile; some of these birds also had proventricular impaction. Most poisoned birds of the other species were emaciated but lacked other gross lesions caused by Pb poisoning. In birds other than mallards, Pb poisoning could not be diagnosed without histological or hematological examinations or analysis of tissues. Poisoned birds of all six species could be reliably separated from control birds by an increase in the protoporphyrin concentrations in the blood and by a decrease in the activity of delta-aminolevulinic acid dehydratase (ALAD) in red blood cells. Hepatic iron (Fe) concentrations varied so much among individual birds that even though median hepatic Fe concentrations increased in poisoned birds, hepatic Fe concentrations were not useful in identifying poisoned birds. Renal intranuclear inclusion bodies occurred in 83% of all birds dying from Pb poisoning. Nephrosis, myocardial necrosis, and arterial fibrinoid necrosis were occasionally present. Median hepatic Pb concentrations varied from 20 ppm (wet wt) in male red-winged blackbirds to 111 ppm in female northern bobwhites. Median renal Pb concentrations varied from 22 ppm in redwinged blackbirds to 190 ppm in female northern bobwhites. Hepatic and renal Pb concentrations varied substantially among birds within each species. Median hepatic and renal Pb concentrations of birds that died were not statistically

This study analyses the incidences and patterns of paraquat poisoning from calls received at the Malaysia National Poison Centre (NPC) since 2004 following the ban of the herbicide (2004-2006) and subsequent restriction up to year 2015. Related reported cases to the centre over twelve years (2004-2015) were retrieved and studied in respect to socio-demographic characteristics, mode and type of poisonings, exposure routes and location of incident. Ages of poisoned victims range from 10 months old to 98 years with males being intoxicated more frequently than females (ratio male to female = 2.7). The age group mainly involved in the poisoning was 20-39 years. The most common mode was intentional (62.8%) followed by unintentional (36.9%). Among the 1232 reported cases, suicidal poisoning was the highest (57.2%); accidental poisoning (30.8%) and occupational poisoning (3.3%). The findings showed an upward trend of suicidal poisoning over the years, clearly emphasizing the need for more stringent and effective enforcement to ensure the safe use of paraquat.

New Zealand has a number of plants, both native and introduced, contact with which can lead to poisoning. The New Zealand National Poisons Centre (NZNPC) frequently receives enquiries regarding exposures to poisonous plants. Poisonous plants can cause harm following inadvertent ingestion, via skin contact, eye exposures or inhalation of sawdust or smoked plant matter. The purpose of this article is to determine the 15 most common poisonous plant enquiries to the NZNPC and provide a review of current literature, discussing the symptoms that might arise upon exposure to these poisonous plants and the recommended medical management of such poisonings. Call data from the NZNPC telephone collection databases regarding human plant exposures between 2003 and 2010 were analysed retrospectively. The most common plants causing human poisoning were selected as the basis for this review. An extensive literature review was also performed by systematically searching OVID MEDLINE, ISI Web of Science, Scopus and Google Scholar. Further information was obtained from book chapters, relevant news reports and web material. For the years 2003-2010 inclusive, a total of 256,969 enquiries were received by the NZNPC. Of these enquiries, 11,049 involved exposures to plants and fungi. The most common poisonous plant enquiries, in decreasing order of frequency, were: black nightshade (Solanum nigrum), arum lily (Zantedeschia aethiopica), kowhai (Sophora spp.), euphorbia (Euphorbia spp.), peace lily (Spathiphyllum spp.), agapanthus (Agapanthus spp.), stinking iris (Iris foetidissima), rhubarb (Rheum rhabarbarum), taro (Colocasia esculentum), oleander (Nerium oleander), daffodil (Narcissus spp.), hemlock (Conium maculatum), karaka (Corynocarpus laevigatus), foxglove (Digitalis purpurea) and ongaonga/New Zealand tree nettle (Urtica ferox). The combined total of enquiries for these 15 species was 2754 calls (representing approximately 25% of all enquiries regarding plant exposures). The signs

Poisoning due to pesticides is an important public health problem worldwide due its morbidity and mortality. In Colombia, there are no exact data on mortality due to pesticide poisoning. To estimate the trend of mortality rate due to pesticide poisoning in Colombia between 1998 and 2011. We carried out a descriptive analysis with the database reports of death as unintentional poisoning, self-inflicted intentional poisoning, aggression with pesticides, and poisoning with non-identified intentionality, population projections between 1998 and 2011, and rurality indexes. Crude and age-adjusted mortality rates were estimated and trends and Spearman coefficients were evaluated. A total of 4,835 deaths were registered (age-adjusted mortality rate of 2.38 deaths per 100,000 people). Mortality rates were higher in rural areas, for self-inflicted intentional poisoning, in men and in age groups between 15 and 39 years old. The trend has been decreasing since 2002. Municipality mortality rates due to unintentional poisoning and aggression correlated significantly with the rurality index in less rural municipalities. Mortality rates due to pesticide poisoning presented a mild decrease between 1998 and 2011. It is necessary to adjust and reinforce the measures conducive to reducing pesticide exposure in order to avoid poisoning and reduce mortality.

Tourists and native inhabitants of tropical and subtropical regions differ significantly with regard to the risk and nature of incidents involving venomous and poisonous animals. While the indigenous population encounters such risks daily during work and other activities, tourists are usually endangered while swimming or diving, or by ingesting toxin-containing fish and/or other seafood. Whether abroad or at home, allergic reactions to the stings of bees, wasps and hornets are probably the most common manifestations of an encounter with a "poisonous animal". Travellers should be well acquainted with the dangers entailed in encountering or ingesting a venomous or poisonous animal--prevention is the most important measure.

Doxorubicin and idarubicin are very effective anticancer drugs in the treatment of human hematological malignancies and solid tumors. These agents are well known topoisomerase II poisons; however, some anthracycline analogs recently have been shown to poison topoisomerase I. In the present work, we assayed novel disaccharide analogs and the parent drug, idarubicin, for their poisoning effects of human topoisomerase I and topoisomerases IIalpha and IIbeta. Drugs were evaluated with a DNA cleavage assay in vitro and with a yeast system to test whether the agents were able to poison the enzymes in vivo. We have found that the test agents are potent poisons of both topoisomerases IIalpha and IIbeta. The axial orientation of the second sugar relative to the first one of the novel disaccharide analogs was shown to be required for poisoning activity and cytotoxicity. Interestingly, idarubicin and the new analogs stimulated topoisomerase I-mediated DNA cleavage at low levels in vitro. As expected, the cytotoxic level of the drug was highly affected by the content of topoisomerase II; nevertheless, the test agents had a yeast cell-killing activity that also was weakly dependent on cellular topoisomerase I content. The results are relevant for the full understanding of the molecular mechanism of topoisomerase poisoning by anticancer drugs, and they define structural determinants of anthracyclines that may help in the rational design of new compounds directed against topoisomerase I.
Hyperbaric oxygen therapy for carbon monoxide poisoning.

PubMed

Weaver, Lindell K

2014-01-01

Despite established exposure limits and safety standards, and the availability of carbon monoxide (CO) alarms, each year 50,000 people in the United States visit emergency departments for CO poisoning. Carbon monoxide poisoning can occur from brief exposures to high levels of CO, or from longer exposures to lower levels. Common symptoms include headaches, nausea and vomiting, dizziness, general malaise, and altered mental status. Some patients may have chest pain, shortness of breath and myocardial ischemia, and may require mechanical ventilation and treatment of shock. Individuals poisoned by CO often go on to develop neurological problems, including cognitive sequelae, anxiety and depression, persistent headaches, dizziness, sleep problems, motor weakness, vestibular and balance problems, gaze abnormalities, peripheral neuropathies, hearing loss, tinnitus and Parkinsonian-like syndrome. While breathing oxygen hastens the removal of carboxyhemoglobin (COHb), hyperbaric oxygen (HBO2) hastens COHb elimination and favorably modulates inflammatory processes instigated by CO poisoning, an effect not observed with breathing normobaric oxygen. Hyperbaric oxygen improves mitochondrial function, inhibits lipid peroxidation transiently, impairs leukocyte adhesion to injured microvasculature, and reduces brain inflammation caused by the CO-induced adduct formation of myelin basic protein. Based upon three supportive randomized clinical trials in humans and considerable evidence from animal studies, HBO2 should be considered for all cases of acute symptomatic CO poisoning. Hyperbaric oxygen is indicated for CO poisoning complicated by cyanide poisoning, often concomitantly with smoke inhalation.

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.

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.
Sodium fluoroacetate poisoning.

PubMed

Proudfoot, Alex T; Bradberry, Sally M; Vale, J Allister

2006-01-01

Sodium fluoroacetate was introduced as a rodenticide in the US in 1946. However, its considerable efficacy against target species is offset by comparable toxicity to other mammals and, to a lesser extent, birds and its use as a general rodenticide was therefore severely curtailed by 1990. Currently, sodium fluoroacetate is licensed in the US for use against coyotes, which prey on sheep and goats, and in Australia and New Zealand to kill unwanted introduced species. The extreme toxicity of fluoroacetate to mammals and insects stems from its similarity to acetate, which has a pivotal role in cellular metabolism. Fluoroacetate combines with coenzyme A (CoA-SH) to form fluoroacetyl CoA, which can substitute for acetyl CoA in the tricarboxylic acid cycle and reacts with citrate synthase to produce fluorocitrate, a metabolite of which then binds very tightly to aconitase, thereby halting the cycle. Many of the features of fluoroacetate poisoning are, therefore, largely direct and indirect consequences of impaired oxidative metabolism. Energy production is reduced and intermediates of the tricarboxylic acid cycle subsequent to citrate are depleted. Among these is oxoglutarate, a precursor of glutamate, which is not only an excitatory neurotransmitter in the CNS but is also required for efficient removal of ammonia via the urea cycle. Increased ammonia concentrations may contribute to the incidence of seizures. Glutamate is also required for glutamine synthesis and glutamine depletion has been observed in the brain of fluoroacetate-poisoned rodents. Reduced cellular oxidative metabolism contributes to a lactic acidosis. Inability to oxidise fatty acids via the tricarboxylic acid cycle leads to ketone body accumulation and worsening acidosis. Adenosine triphosphate (ATP) depletion results in inhibition of high energy-consuming reactions such as gluconeogenesis. Fluoroacetate poisoning is associated with citrate accumulation in several tissues, including the brain. Fluoride

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

Risk factors for acute pesticide poisoning in Sri Lanka.

PubMed

van der Hoek, Wim; Konradsen, Flemming

2005-06-01

This report describes the characteristics of patients with acute pesticide poisoning in a rural area of Sri Lanka and, for intentional self-poisoning cases, explores the relative importance of the different determinants. Data were collected for 239 acute pesticide-poisoning cases, which were admitted to two rural hospitals in Sri Lanka. Sociodemographic characteristics, negative life events and agricultural practices of the intentional self-poisoning cases were compared with a control group. Most cases occurred among young adults and the large majority (84%) was because of intentional self-poisoning. Case fatality was 18% with extremely high case fatality for poisoning with the insecticide endosulfan and the herbicide paraquat. Cases were generally younger than controls, of lower educational status and were more often unemployed. No agricultural risk factors were found but a family history of pesticide poisoning and having ended an emotional relationship in the past year was clearly associated with intentional self-poisoning. The presence of mental disorders could only be assessed for a subsample of the cases and controls and this showed that alcohol dependence was a risk factor. This study shows that acute pesticide poisoning in Sri Lanka is determined by a combination of sociodemographic and psychological factors. Suggestions are given for interventions that could control the morbidity and mortality due to acute pesticide poisoning in developing countries.

To understand the situations of pesticide poisoning in Huzhou and take preventive strategy and measures against the pesticide poisoning. Case reports between 2006 and 2009 in the data base of reporting system for occupational diseases were computed by Excel for windows and statistical significance by SPSS12.0. A total of 2298 patients were reported from 2006 to 2009. Among them, the incidence of occupational poisoning accounted for 25.59% (588 cases), including 4 fatalities (fatality rate, 0.68%). Male patients (458 cases, 77.89%) were more than female ones (130 cases, 22.11%) in occupational pesticides poisoning. Summer and autumn were the most seasons in occupational pesticides poisoning occurring. The incidence of non-occupational pesticides poisoning accounted for 74.41% (1710, cases), including 112 fatalities (fatality rate, 6.55%). Female patients (952 cases, 55.67%) were more than male ones (758 cases, 44.33%) in non-occupational pesticides poisoning. 15 - 55 years were the highest incidences among non-occupational pesticides poisoning patients. Insecticides especially organophosphorus insecticides such as methamidophos, parathion, and omethoate comprised a higher proportion, accounting for 79.98% of the pesticides poisoning. The incidence and the fatality rate of occupational pesticide poisoning were reduced in the city. However, more attention should be paid to non-occupational pesticides poisoning. To decrease the numbers of pesticide poisoning and the risks of death, the relevant departments should take preventive strategy and measures against the pesticide poisoning.

Lead poisoning is an intoxication resulting from absorption of hazardous levels of lead into body tissues. Lead pellets from shot shells, when ingested, are the most common source of lead poisoning in migratory birds. Other far less common sources include lead fishing sinkers, mine wastes, paint pigments, bullets, and other lead objects that are swallowed.
webPOISONCONTROL: can poison control be automated?

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.

Pesticide poisoning is very common in Nepal. Hospital based studies from various parts of Nepal have shown that poisoning with organophosphorus compounds is the most common type of poisoning. Current study is undertaken to see the pattern of organophosphorus poisoning and to identify the common risk factors among the cases. If the risk factors are modifiable, attempts in addressing the risk factors and decreasing the likelihood of poisoning will certainly be fruitful in reducing the morbidity and mortality associated with organophosphorus poisoning. To assess the risk factors of organophosphorus poisoning which is major public health problem in Nepal. A community based retrospective study of 75 cases of organophosphate poisoning who were brought to the emergency department of Dhulikhel hospital over the period of 3 years. Basic information was collected from hospital records and home visits were made to study the risk factors. Data were collected through interviews of the study population and their family members using a pre-designed questionnaire. In this study 75 cases and their families were interviewed of which there were 59% males and 42% females (M/F ratio of 1:1.4). The majority (40%) of the poisoning cases were in the age group 25-34 years. Lower literacy level showed positive association with the incidence of poisoning. Occupation wise vast majority (80%) of the cases were engaged in agricultural work. Suicidal attempts by ingesting organophosphate compounds were high in farmers and females. In this study, majority of the poisoning were attempts of intentional self harm. Agriculture workers and females are high risk groups and may be associated with the fact that they have easy access to the poison. Interventions directed towards health education, counseling, and enforcement of laws restricting the availability and use of harmful pesticides may help in reducing such events in future.

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

A 4-year-old girl was brought into the emergency department vomiting after having had ingested a laundry detergent capsule (LDC) from under the sink at her house. What is the risk of LDC poisoning? What can be done to treat these children? Laundry detergent capsules are relatively new to supermarket shelves in North America, and there has been an emergence of case reports in the literature describing LDC poisoning, which is worse than poisoning from other laundry detergents. Very little is known about the mechanisms causing these severe reactions, which include airway compromise and esophageal perforation, but the attractive appearance of these capsules and easy access at home has governments and health officials concerned about an increase in poisoning. No residual problems have been associated with these cases to date; however, further research is needed to assess long-term effects.
Suspected poisoning of domestic animals by pesticides.

Caloni, Francesca; Cortinovis, Cristina; Rivolta, Marina; Davanzo, Franca

2016-01-01

A retrospective study was carried out by reviewing all suspected cases of domestic animal poisoning attributed to pesticides, reported to the Milan Poison Control Centre (MPCC) between January 2011 and December 2013. During this period, pesticides were found to be responsible for 37.3% of all suspected poisoning enquiries received (815). The most commonly species involved was the dog (71.1% of calls) followed by the cat (15.8%), while a limited number of cases involved horses, goats and sheep. Most cases of exposure (47.1%) resulted in mild to moderate clinical signs. The outcome was reported in 59.9% of these cases, with death occurring in 10.4% of them. Insecticides (40.8%) proved to be the most common group of pesticides involved and exposure to pyrethrins-pyrethroids accounted for the majority of calls. According to the MPCC data, there has been a decrease in the number of suspected poisonings cases attributed to pesticides that have been banned by the EU, including aldicarb, carbofuran, endosulfan and paraquat. In contrast, there has been an increase of suspected poisoning cases attributed to the neonicotinoids, imidacloprid and acetamiprid, probably due to their widespread use in recent years. Cases of suspected poisoning that involved exposure to rodenticides accounted for 27.6% of calls received by the MPCC and anticoagulant rodenticides were the primary cause of calls, with many cases involving brodifacoum and bromadiolone. Herbicides were involved in 14.2% of calls related to pesticides and glyphosate was the main culprit in cases involving dogs, cats, horses, goats and sheep. As far as exposure to molluscicides (11.5%) and fungicides (5.9%), most of the cases involved dogs and the suspected poisoning agents were metaldehyde and copper compounds respectively. The data collected are useful in determining trends in poisoning episodes and identifying newly emerging toxicants, thus demonstrating the prevalence of pesticides as causative agents in animal
A Narrative Review of Acute Adult Poisoning in Iran

2017-01-01

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. PMID:28761199

Was it poisoning?

The aim of post-mortem toxicology is to help establish the role that drugs or other poisons played in a death, or in events immediately before death. If self-poisoning is suspected then the diagnosis may be straightforward and all that may be required is confirmation of the agents involved. If the cause of death is not immediately obvious, however, then suspicion of possible poisoning is of course crucial. Blood sampling (needle aspiration, peripheral vein, e.g. femoral, ideally after proximal ligation) before opening the body, minimises the risk of sample contamination with, for example, gut contents or urine. The site of blood sampling should always be recorded. Other specimens (stomach contents, urine, liver, vitreous humor) may also be valuable and may be needed to corroborate unexpected or unusual findings in the absence of other evidence. The availability of ante-mortem specimens should not preclude post-mortem sampling. Appropriate sample preservation, transport, and storage are mandatory. Interpretation of post-mortem toxicology must take into account what is known of the clinical pharmacology, including pharmacokinetics, and toxicology of the agent(s) in question, the circumstances under which death occurred including the possible mechanism(s) of exposure, and other factors such as the sample(s) analysed and the analytical methods used. It was thought that concentrations of poisons measured in blood obtained at autopsy reflected the situation peri-mortem. However, we now know that changes may occur in the composition of body fluids, even peripheral blood, after death. Such changes are likely to be greater with centrally-acting drugs such as clozapine with large volumes of distribution, and may perhaps be minimised by prompt refrigeration of the body and performing the autopsy quickly. Better training in analytical toxicology is needed for pathologists and others who may be called upon to interpret toxicological data for the Courts. Undue reliance on

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.

Data from the National Vital Statistics System, Mortality File. The age-adjusted rate for opioid-analgesic poisoning deaths nearly quadrupled from 1.4 per 100,000 in 1999 to 5.4 per 100,000 in 2011. Although the opioid-analgesic poisoning death rates increased each year from 1999 through 2011, the rate of increase has slowed since 2006. Natural and semisynthetic opioid analgesics, such as hydrocodone, morphine, and oxycodone, were involved in 11,693 drug-poisoning deaths in 2011, up from 2,749 deaths in 1999. Benzodiazepines were involved in 31% of the opioid-analgesic poisoning deaths in 2011, up from 13% of the opioid-analgesic poisoning deaths in 1999. During the past decade, adults aged 55-64 and non-Hispanic white persons experienced the greatest increase in the rates of opioid-analgesic poisoning deaths. Poisoning is the leading cause of injury death in the United States (1). Drugs-both illicit and pharmaceutical-are the major cause of poisoning deaths, accounting for 90% of poisoning deaths in 2011. Misuse or abuse of prescription drugs, including opioid-analgesic pain relievers, is responsible for much of the recent increase in drug-poisoning deaths (2). This report highlights trends in drug-poisoning deaths involving opioid analgesics (referred to as opioid-analgesic poisoning deaths) and updates previous Data Briefs on this topic.

The aim of the presented study was to trace the trends and characteristics of acute poisonings in Poland, including the rate, type, and causal agents, over a long period of time (1970-2000) to define the dynamics of changes and major causes of poisoning-related mortality. The analysis was based on the data obtained from the patients' records submitted by all poison centers in Poland (Gdańsk, Kraków, Lublin, Łódź, Poznań, Sosnowiec, Rzeszów, Warszawa, and Wroclaw). Drugs were the most frequent group of chemical substances, responsible for more than 50% of all admissions because of acute poisonings. From 1980, the rate of drug poisonings showed a slightly downward trend from 56.4% in 1980 to 48.8% in 2000. Ranked second with respect to the prevalence rate were alcohol poisonings. A clear upward trend from 8.0% in 1980 to as high as 30.8% in 2000 was noted in this category. Poisonings with carbon monoxide became less frequent, ranging from 15.3 to 5.1%, respectively in the aforesaid years. The percentage of poisonings with pesticides, corrosives and metal compounds have been reduced in recent years. The greatest number of lethal outcomes was also due to poisonings with alcohols and drugs. The highest mortality ratio was recorded for ethylene glycol, methanol and Amanita phalloides poisonings. A constantly growing number of acute poisonings in Poland makes it necessary for all the medical and other professionals involved (clinical toxicologists, diagnostic laboratory staff, and poison information specialists) to enhance and coordinate their efforts. These activities should be focused on: (a) better and faster accessibility of all information on the agent of poisoning, possible health effects, and methods of treatment to support the medical staff; (b) selection of the most effective methods to eliminate poisons from the system and improve further therapy, and (c) better accessibility of antidotes.

The agricultural industry is the largest economic sector in Palestine and is characterized by extensive and unregulated use of pesticides. The objective of this study was to analyze phone calls received by the Poison Control and Drug Information Center (PCDIC) in Palestine regarding pesticide poisoning. All phone calls regarding pesticide poisoning received by the PCDIC from 2006 to 2010 were descriptively analyzed. Statistical Package for Social Sciences (SPSS version 16) was used in statistical analysis and to create figures. A total of 290 calls regarding pesticide poisoning were received during the study period. Most calls (83.8%) were made by physicians. The average age of reported cases was 19.6 ± 15 years. Pesticide poisoning occurred mostly in males (56.9%). Pesticide poisoning was most common (75, 25.9%) in the age category of 20-29.9 years. The majority (51.7%) of the cases were deliberate self-harm while the remaining was accidental exposure. The majority of phone calls (250, 86.2%) described oral exposure to pesticides. Approximately one third (32.9%) of the cases had symptoms consistent with organophosphate poisoning. Gastric lavage (31.7%) was the major decontamination method used, while charcoal was only utilized in 1.4% of the cases. Follow up was performed in 45.5% of the cases, two patients died after hospital admission while the remaining had positive outcome. Pesticide poisoning is a major health problem in Palestine, and the PCDIC has a clear mission to help in recommending therapy and gathering information.

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

Lead poisoning is a historic universal disease. Acute or chronic lead exposure may cause reversible or even permanent damages in human beings. Environmental lead exposure is a global health concern in children. Occupational lead poisoning is still a health issue, particularly in developing countries. During the last decades, new methods and medications have been advocated for the prevention and treatment of lead poisoning. This review deals mainly with recent developments in the management of lead poisoning. Sources of lead exposure are introduced, and methods for the primary prevention of lead poisoning are discussed. Details for the screening of adults and children are also explained to serve as a practical guideline for the secondary prevention. Standard chelation therapy in different groups and up-to-date less toxic new medications for the treatment of lead poisoning are finally discussed. Our published clinical research on the therapeutic effects of garlic tablets in mild to moderate occupational lead poisoning will also be discussed.

Answer Laundry detergent capsules are relatively new to supermarket shelves in North America, and there has been an emergence of case reports in the literature describing LDC poisoning, which is worse than poisoning from other laundry detergents. Very little is known about the mechanisms causing these severe reactions, which include airway compromise and esophageal perforation, but the attractive appearance of these capsules and easy access at home has governments and health officials concerned about an increase in poisoning. No residual problems have been associated with these cases to date; however, further research is needed to assess long-term effects. PMID:24336541
Accidental poisoning with "Chinese chalk".

We present a 1.5-year old, 11 kg, female infant with a history of bronchial hyper-responsiveness who accidentally ingested half of a "Chinese chalk". A day later, the infant showed vomiting, cough, fever, drowsiness, and irritability and her clinical conditions progressively worsened. She was admitted to the emergency department with cough, respiratory distress, and hepatomegaly. It has been reported that the chalk may contain deltamethrin and cypermethrin. The patient was successfully treated with supportive therapy. This report identifies "Chinese chalk" as a potential source of accidental poisoning in children and should be considered as part of the differential diagnoses in the emergency rooms since poisoning with these compounds may be misdiagnosed as organophosphate poisoning due to the presentation of similar symptoms.

Poisoning: fact or fiction?

PubMed

Flanagan, Robert J

2012-01-01

Analytical toxicology is a complex discipline. Simply detecting a poison in a biological sample does not necessarily mean that the individual from whom the sample was obtained had been poisoned. An analysis can prove exposure and perhaps give an indication of the magnitude of exposure, but the results have to be placed in proper context. Even if sampling was ante-mortem an analysis does not necessarily prove the effects that the drug or poison had on the victim immediately before or at the time of sampling. Tolerance is one big issue, the mechanism of exposure (how the drug got into the body) is another, and of course with post-mortem work there are always additional considerations such as site of sample collection and the possibility of post-mortem change in analyte concentration. There are also questions of quality and reliability, and whether a particular analysis and the interpretation placed upon the result are appropriate in a particular case.

Pesticide poisoning is a major cause of death in the world. The objective of this study was to examine the trends of pesticide poisoning deaths and their epidemiologic characteristics in South Korea. We evaluated the age-standardized mortality rates from pesticide-related deaths (intentional self-poisoning, accidental poisoning, assault, undetermined intent poisoning) in South Korea from 1996 through 2005, using registered death data obtained from the Korea National Statistical Office. The regional rurality index was calculated and correlation analyses were used to estimate the association with pesticide poisoning mortality. The number of pesticide poisoning deaths from 1996 through 2005 was 25,360, which accounted for 58.3% of the total poisoning fatalities. The age-standardized mortality rates by pesticide poisoning significantly increased from 4.42 to 6.42 per 100,000 population, whereas the total death rate was decreased in the same period. Intentional self-poisoning was the majority cause of death from pesticides (84.8% of total pesticide poisoning deaths). The majority of the pesticide poisoning deaths were men, over 50 years old, with education less than middle school, and residing in rural areas. The rate of pesticide poisoning deaths was the highest in the farming period and was significantly correlated with the rurality index of each region. Pesticide poisoning deaths substantially increased during the 10-year study period, and showed demographic, seasonal and regional variations. More intensive intervention efforts to reduce pesticide mortality should become a public health priority in South Korea.
Alkaloid-Containing Plants Poisonous to Cattle and Horses in Europe.

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.

Scombroid fish poisoning in Israel, 2005-2007.

PubMed

Lavon, Ophir; Lurie, Yael; Bentur, Yedidia

2008-11-01

Scombroid fish poisoning is an acute illness caused by consumption of fish containing high concentrations of histamine. Improper handling of fish leads to bacterial contamination. Bacterial enzymes convert histidine to histamine. Symptoms develop quickly and resemble an immunoglobulin E-mediated allergic reaction. The diagnosis is often missed. Serious complications (e.g., bronchospasm, hypotension) are infrequent. To evaluate the prevalence and characteristics of scombroid fish poisoning in Israel as reported to the national poison information center. We conducted a retrospective poison center chart review from January 2005 to December 2007. During the study period, 21 events of scombroid poisoning involving 46 patients were recorded. Tuna was the commonest fish consumed (84.7%). Clinical manifestations developed within 20 minutes in 65.2% of the patients. The main clinical manifestations included rash (41%), flushing (37%), gastrointestinal complaints (37%) and headache (30.4%). About 25% had abnormal vital signs; two patients developed hypotension. Treatment was supportive and included mainly H1-antagonists (65.2%) and fluids (13%). Five patients were initially misdiagnosed as having an allergic reaction and were treated with corticosteroids (four patients) and epinephrine (one patient). Scombroid fish poisoning should be suspected in patients with histamine-like manifestations that are temporally related to fish (mainly tuna) consumption, especially in outbreaks. Although scombroid poisoning is often self-limited and responds well to antihistamines, prolonged observation may be required as severe toxicity can supervene. Proper handling of fish and urgent notification of the Ministry of Health are mandatory in order to prevent this potentially serious public heath problem.
Metal Poisons in Waste Tanks (U)

1996-10-14

Many of the storage tanks with waste from processing fissile materials contain, along with the fissile material, metals which may serve as nuclear criticality poisons. It would be advantageous to the criticality evaluation of these wastes if it can be demonstrated that the poisons remain with the fissile materials and if an always safe poison-to-fissile ratio can be established. The first task, demonstrating that the materials stay together, is the job of the chemist, the second, demonstrating an always safe ratio, is the job of the physicist. The latter task is the object of this paper
Pancreatitis in wild zinc-poisoned waterfowl

USGS Publications Warehouse

Sileo, Louis; Beyer, W. Nelson; Mateo, Rafael

2003-01-01

Four waterfowl were collected in the TriState Mining District (Oklahoma, Kansas and Missouri, USA), an area known to be contaminated with lead, cadmium and zinc (Zn). They were part of a larger group of 20 waterfowl collected to determine the exposure of birds to metal contamination at the site. The four waterfowl (three Branta canadensis, one Anas platyrhynchos) had mild to severe degenerative abnormalities of the exocrine pancreas, as well as tissue (pancreas, liver) concentrations of Zn that were considered toxic. The mildest condition was characterized by generalized atrophy of exocrine cells that exhibited cytoplasmic vacuoles and a relative lack of zymogen. The most severe condition was characterized by acini with distended lumens and hyperplastic exocrine tissue that completely lacked zymogen; these acini were widely separated by immature fibrous tissue. Because the lesions were nearly identical to the lesions reported in chickens and captive waterfowl that had been poisoned with ingested Zn, and because the concentrations of Zn in the pancreas and liver of the four birds were consistent with the concentrations measured in Zn-poisoned birds, we concluded that these waterfowl were poisoned by Zn. This may be the first reported case of zinc poisoning in free-ranging wild birds poisoned by environmental Zn.

The goal of this retrospective cohort study of pediatric patients exposed to flumazenil was to identify the frequency of seizures. Included patient were those aged 12 years or younger who received flumazenil, who had evidence of clinical poisoning as defined by an altered mental status, and who were reported to the California Poison Control System for the period 1999 to 2008. Data variables were age, sex, seizure, death, acute exposure to a benzodiazepine, drugs of exposure, long-term use of benzodiazepines, history of a seizure disorder, mental status before flumazenil administration, and poison center recommendation of flumazenil (yes/no). Eighty-three patients were included. Forty-eight (58%) of this subset were female. Median age was 2 years (range, 3 months-12 years). Seventy (84%) patients were younger than 5 years. Of the 83 patients, 68 (82%) were allegedly exposed to a benzodiazepine; whereas, 12 (15%) had been allegedly exposed to a proconvulsant drug. No flumazenil-related seizures occurred (0% with 95% confidence interval, 0%-4%). The California Poison Control System recommended flumazenil use in 60 (72%) of the 83 cases, and 48 of these had been allegedly exposed to a benzodiazepine. No flumazenil-associated seizures occurred among allegedly benzodiazepine- and non-benzodiazepine-poisoned pediatric patients aged 12 years or younger.

Methanol poisoning results in neurological complications including visual disturbances, bilateral putaminal hemorrhagic necrosis, parkinsonism, cerebral edema, coma, or seizures. Almost all reported cases of methanol poisoning are caused by oral ingestion of methanol. However, recently there was an outbreak of methanol poisoning via non-oral exposure that resulted in severe neurological complications to a few workers at industrial sites in Korea. We present 3 patients who had severe neurological complications resulting from non-oral occupational methanol poisoning. Even though initial metabolic acidosis and mental changes were improved with hemodialysis, all of the 3 patients presented optic atrophy and ataxia or parkinsonism as neurological complications resulting from methanol poisoning. In order to manage it adequately, as well as to prevent it, physicians should recognize that methanol poisoning by non-oral exposure can cause neurologic complications.

Caustic products are responsible for the most serious cases of poisoning, which are always emergency cases. Application of current intervention procedures has decreased both morbidity and mortality. Water-diluted bleach, the ingestion of which remains extremely frequent, is a moderate irritant rather than a caustic product. Emission of gas produced when mixing bleach with other agents can be responsible for choking gas poisoning. Anionic and nonionic detergents are mostly dangerous because of their foam-producing properties. Mercury vapours and methanol are other potentially hazardous products.

We examined the causes and mortality of poisoning in the province of Mazandaran. In all, 1751 poisoning cases referred to four main hospitals over a three-year period (1997-2000) were included. More poisoning cases were females (55.5%) than males (45.5%) but the proportional mortality for males was greater than for females (65% versus 35%). The greatest proportion of poisonings occurred between the ages of 16 and 25 years. Most frequent was intentional poisoning, followed by accidental and occupational poisoning. Medicines were the most common cause, followed by chemicals such as pesticides. Poisoning by opiates, aluminium or zinc phosphide, rodenticides, petroleum and ethanol intoxication was also observed. Pesticide poisoning was most frequently fatal.

OBJECTIVES: Most data on self-poisoning in rural Asia have come from secondary hospitals. We aimed to: assess how transfers from primary to secondary hospitals affected estimates of case-fatality ratio (CFR); determine whether there was referral bias according to gender or poison; and estimate the annual incidence of all self-poisoning, and of fatal self-poisoning, in a rural developing-world setting. METHODS: Self-poisoning patients admitted to Anuradhapura General Hospital, Sri Lanka, were reviewed on admission from 1 July to 31 December 2002. We audited medical notes of self-poisoning patients admitted to 17 of the 34 surrounding peripheral hospitals for the same period. FINDINGS: A total of 742 patients were admitted with self-poisoning to the secondary hospital; 81 died (CFR 10.9%). 483 patients were admitted to 17 surrounding peripheral hospitals. Six patients (1.2%) died in peripheral hospitals, 249 were discharged home, and 228 were transferred to the secondary hospital. There was no effect of gender or age on likelihood of transfer; however, patients who had ingested oleander or paraquat were more likely to be transferred than were patients who had taken organophosphorus pesticides or other poisons. Estimated annual incidences of self-poisoning and fatal self-poisoning were 363 and 27 per 100,000 population, respectively, with an overall CFR of 7.4% (95% confidence interval 6.0-9.0). CONCLUSION: Fifty per cent of patients admitted to peripheral hospitals were discharged home, showing that CFRs based on secondary hospital data are inflated. However, while incidence of self-poisoning is similar to that in England, fatal self-poisoning is three times more common in Sri Lanka than fatal self-harm by all methods in England. Population based data are essential for making international comparisons of case fatality and incidence, and for assessing public health interventions. PMID:16628300

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

Poison ivy, Toxicodendron radicans, and poison oaks, T. diversilobum and T. pubescens, are perennial woody species of the Anacardiaceae and are poisonous, containing strong allergens named urushiols that cause allergic contact dermatitis. Poison ivy is a species distributed from North America to East Asia, while T. diversilobum and T. pubescens are distributed in western and eastern North America, respectively. Phylogreography and population structure of these species remain unclear. Here, we developed microsatellite markers, via constructing a magnetic enriched microsatellite library, from poison ivy. We designed 51 primer pairs, 42 of which successfully yielded products that were subsequently tested for polymorphism in poison oak, and three subspecies of poison ivy. Among the 42 loci, 38 are polymorphic, while 4 are monomorphic. The number of alleles and the expected heterozygosity ranged from 1 to 12 and from 0.10 to 0.87, respectively, in poison ivy, while varied from 2 to 8 and, from 0.26 to 0.83, respectively in poison oak. Genetic analysis revealed distinct differentiation between poison ivy and poison oak, whereas slight genetic differentiation was detected among three subspecies of poison ivy. These highly polymorphic microsatellite fingerprints enable biologists to explore the population genetics, phylogeography, and speciation in Toxicodendron.

Lead poisoning was diagnosed post-mortem in 34 simian primates, 11 parrots, and 3 Australian fruit bats at the National Zoological Park. Diagnoses were made by the finding of acid-fast intranuclear inclusion bodies in renal epithelia or hepatocytes and, in most cases, by finding excess lead in samples of liver. The estimated prevalence of lead intoxication among autopsied primates and parrots was 44% and 50% respectively. Leaded paint was found in many animal enclosures at this zoo and it was available to all the lead-poisoned animals in this study. The finding of renal intranuclear inclusion bodies in animals at several zoos,more » scattered reports of lead intoxication of animals dwelling in various zoos, the occurrence of leaded paint in many zoos and the high incidence of lead poisoning at this zoo, indicated that lead poisoning of zoo animals is much more common than was previously thought.« less

2011-01-01

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.

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.

Recent Advances in the Treatment of Organophosphorous Poisonings

PubMed Central

Balali-Mood, Mahdi; Saber, Hamidreza

2012-01-01

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. Given the signs and symptoms of organophosphorous poisoning, health professionals should remain updated about the recent advances in treatment of organophosphorous poisoning

Abstract We designed a population-based retrospective cohort study to investigate the association between the event of benzodiazepine (BZD) poisoning and the risk of acute pancreatitis. In the present study, 12,893 patients with BZD poisoning during 2000 to 2011 were enrolled and matched with 4 comparison patients according to mean age and sex. We determined the cumulative incidences and adjusted hazard ratios of acute pancreatitis. A significant association was observed between BZD poisoning and acute pancreatitis. After adjustment for potential risk factors, the patients with BZD poisoning had a 5.33-fold increased risk of acute pancreatitis compared with the controls without BZD poisoning (HR = 5.33, 95% CI = 2.26–12.60). The results revealed that acute pancreatitis in patients with BZD poisoning occurred in a follow-up time of ≤1 month (HR = 50.0, P < .001), and the risk of acute pancreatitis was no different between the patients with and without BZD poisoning when the follow-up time was >1 month (HR = 1.07, P > .05). This population-based study revealed the positive correlation between the event of BZD poisoning and an increased risk of acute pancreatitis. The findings warrant further large-scale and in-depth investigation. PMID:26717383

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.

Novel psychoactive substances or 'legal highs' can be defined as psychoactive substances that have been developed to avoid existing drug control measures. Consistency of name, but with change in the content of the product, may cause harm. This could result in clusters of users being poisoned and developing unexpected physical and psychiatric symptoms. We describe such an event and the clinical phenotypes of a cluster of patients poisoned with a novel psychoactive substance in 'ivory wave' and analyze data from the National Poisons Information Service (NPIS) to estimate use across the United Kingdom. In addition, the likely active ingredient in this cluster of 'ivory wave' poisonings was identified. An analysis of consecutive patients attending the Royal Infirmary of Edinburgh emergency department in July and August 2010 with self-reported 'ivory wave' use was performed. Over a similar time frame, poisons enquiries regarding 'ivory wave' to the UK NPIS, by telephone and via the internet-based TOXBASE(®) poisons database ( www.toxbase.org ), were analyzed. A sample of 'ivory wave' powder and biological fluids from poisoned patients were investigated to determine the active ingredient. Thirty four emergency attendances due to 'ivory wave' toxicity were identified. The mean +/- SD (range) age was 28.6 +/- 7.8 (16-44) years. Patients demonstrated a toxidrome which lasted several days, characterized by tachycardia (65%), tachypnoea (76%), dystonia (18%), rhabdomyolysis (96%), leucocytosis (57%), agitation (62%), hallucinations (50%), insomnia (32%) and paranoia (21%). Enquiries to NPIS suggest that 'ivory wave' poisoning occurred throughout the United Kingdom. A sample of 'ivory wave' powder was analyzed and found to contain desoxypipradrol, which was also identified in biological fluids from 4 out of 5 patients tested. A cluster of cases presenting after use of a novel psychoactive substance was identified in Edinburgh and desoxypipradrol was identified as the likely
Residential carbon monoxide poisoning from motor vehicles.

Although morbidity and mortality from accidental carbon monoxide (CO) poisoning are high in the United States, identification of common but poorly recognized sources should help prevention efforts. The study aimed to describe CO poisoning of home occupants due to a vehicle left running in an attached garage. News stories reporting incidents of US CO poisoning were collected daily from March 2007 to September 2009 via a news.Google.com search and data extracted. Patients were individuals reported in the media to have been poisoned with CO in their home by a vehicle running in the attached garage. Main outcome measures were frequency of occurrence, geographic distribution, patient demographics, and mortality. Of 837 CO poisoning incidents reported in US news media over 2 and a half years, 59 (8%) were the result of a vehicle left running in the garage. The elderly were disproportionately affected, with incidents most common in states with larger elderly populations and 29% of cases with age specified occurring in individuals older than 80 years. Among those older than 80 years, 15 of 17 were found dead at the scene. Residential CO poisoning from a vehicle running in the garage is common, disproportionately affects the elderly, has a high mortality rate, and should be preventable with a residential CO alarm.

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.

Jatropha curcas L. is an inedible plant belonging to the Euphorbiaceae family that is growing in subtropical zones of all continents. We report a series of 24 cases of poisoning with J. curcas seeds or fruits reported to poison centers in Paris and Marseille between December 2000 and June 2014. Fifteen adults and 9 children ingested J. curcas seeds or fruits. All patients experienced gastrointestinal disorders, within the first hours following ingestion: nausea, vomiting, diarrhea and abdominal pain. Laboratory investigations performed in 10 patients revealed minor abnormalities: CK elevation (8 cases), dehydration (5 cases) with moderate elevation of serum creatinine levels (3 cases), and mildly increased serum bilirubin (8 cases). Complete remission of all clinical signs was observed within 48 hours in the 20 cases for which the outcome was known. Previously published cases of J. curcas poisoning were very similar to ours: As in our series, gastrointestinal disorders were always present. They were sometimes associated with neurological or cardiovascular signs, and hepatic or renal disorders; these were generally interpreted as complications of severe gastroenteritis, although direct toxic effects could not be formally excluded. In most cases, simple supportive measures were sufficient to ensure complete recovery within 24-48 hours. J Curcas poisoning incidence is certainly increasing because the plant is cultivated to produce biodiesel and is now largely present in most subtropical countries. As a consequence, local health professionals should be informed of the toxic properties of this plant.

A specific surveillance program has been set up to monitor avian scavenger populations in the French Pyrenean Mountains, hosting a high proportion of the French populations. The two main purposes of the study were to identify all causes of death and to investigate poisoning cases. All 170 birds found dead during the 7-year program were submitted to full necropsy, X-Ray, parasitological investigations and consistent analytical toxicology screenings (Cholinesterase inhibitors, anticoagulant rodenticides, organochlorine insecticides, Pb, Cd). Over the study period, 8 Bearded Vultures, 120 Griffon Vultures, 8 Egyptian Vultures and 34 Red kites were eventually collected. Mortality events were often multifactorial, but poisoning was by far the most common cause of death (24.1%), followed by trauma/fall (12%), bacterial diseases and starvation (8%) and electrocution (6%). Illicit use of banned pesticides was identified as a common cause of poisoning (53% of all poisoning cases) and lead poisoning was also identified as a significant toxicant issue (17% of all poisoning cases). Lead isotopic signature could be associated primarily with ammunition. Last, a positive association between trauma and lead contamination was detected, indicating that lead could be a significant contributor to different causes of death. These results urge for severe restrictions on the use of lead ammunition to prevent scavengers from detrimental exposure. Copyright © 2015 Elsevier Inc. All rights reserved.
Pharmacological treatment of cardiac glycoside poisoning.

2016-03-01

Cardiac glycosides are an important cause of poisoning, reflecting their widespread clinical usage and presence in natural sources. Poisoning can manifest as varying degrees of toxicity. Predominant clinical features include gastrointestinal signs, bradycardia and heart block. Death occurs from ventricular fibrillation or tachycardia. A wide range of treatments have been used, the more common including activated charcoal, atropine, β-adrenoceptor agonists, temporary pacing, anti-digoxin Fab and magnesium, and more novel agents include fructose-1,6-diphosphate (clinical trial in progress) and anticalin. However, even in the case of those treatments that have been in use for decades, there is debate regarding their efficacy, the indications and dosage that optimizes outcomes. This contributes to variability in use across the world. Another factor influencing usage is access. Barriers to access include the requirement for transfer to a specialized centre (for example, to receive temporary pacing) or financial resources (for example, anti-digoxin Fab in resource poor countries). Recent data suggest that existing methods for calculating the dose of anti-digoxin Fab in digoxin poisoning overstate the dose required, and that its efficacy may be minimal in patients with chronic digoxin poisoning. Cheaper and effective medicines are required, in particular for the treatment of yellow oleander poisoning which is problematic in resource poor countries. © 2015 The British Pharmacological Society.

Abstract The present study evaluated the dementia risk after carbon monoxide poisoning (CO poisoning). Using the National Health Insurance Research Database of Taiwan, a total of 9041 adults newly diagnosed with CO poisoning from 2000 to 2011 were identified as the CO poisoning cohort. Four-fold (N = 36,160) of non-CO poisoning insured people were randomly selected as controls, frequency-matched by age, sex, and hospitalization year. Incidence and hazard ratio (HR) of dementia were measured by the end 2011. The dementia incidence was 1.6-fold higher in the CO exposed cohort than in the non-exposed cohort (15.2 vs 9.76 per 10,000 person-years; n = 62 vs 174) with an adjusted HR of 1.50 (95% CI = 1.11–2.04). The sex- and age-specific hazards were higher in male patients (adjusted HR = 1.74, 95% CI = 1.20–2.54), and those aged <=49 years (adjusted HR = 2.62, 95% CI = 1.38–4.99). CO exposed patients with 7-day or longer hospital stay had an adjusted HR of 2.18 (95% CI = 1.42, 3.36). The CO poisoning patients on hyperbaric oxygen (HBO2) therapy had an adjusted HR of 1.80 (95% CI = 0.96–3.37). This study suggests that CO poisoning may have association with the risk of developing dementia, which is significant for severe cases. The effectiveness of HBO2 therapy remains unclear in preventing dementia. Patients with CO poisoning are more prevalent with depression. PMID:26735545

Do poison center triage guidelines affect healthcare facility referrals?

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 < 0.001) and iron (p = 0.0013). The model explained 31.7% of the referral variation for acetaminophen but only 4.1% of the variation for iron. There is great 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 poisoning appears after ingestion of contaminated fish from tropical coral reefs. Due to the diversity of clinical symptoms and the absence of a specific test in humans, the diagnosis is often difficult. A retrospective study of 10 patients consulting for a clinical and epidemiological picture compatible with ciguatera poisoning after a trip to tropical countries between 1993 and 2000. Most infections but one were acquired in the Caribbean area and there were 8 females. Clinical manifestations started within the first 24 hours after fish ingestion. Chief symptoms were diarrhea and nausea, followed by neurological symptoms, mainly limbs paresthesias that persisted for several weeks. The severity of clinical symptoms was variable and not related to age or initial symptoms. Ciguatera poisoning has to be considered in the diagnosis of acute gastroenteritis affecting travellers to tropical areas.

Organophosphates and carbamates are insecticides that are associated with high human mortality. The purpose of this study is to investigate the prognostic factors affecting survival in patients with cholinesterase inhibitor (CI) poisoning. This study included 92 patients with CI poisoning in the period from January 2005 to August 2013. We divided these patients into 2 groups (survivors vs. non-survivors), compared their clinical characteristics, and analyzed the predictors of survival. The mean age of the included patients was 56 years (range, 16-88). The patients included 57 (62%) men and 35 (38%) women. When we compared clinical characteristics between the survivor group (n=81, 88%) and non-survivor group (n=11, 12%), there were no differences in renal function, pancreatic enzymes, or serum cholinesterase level, except for serum bicarbonate level and APACHE II score. The serum bicarbonate level was lower in non-survivors than in survivors (12.45±2.84 vs. 18.36±4.73, P<0.01). The serum APACHE II score was higher in non-survivors than in survivors (24.36±5.22 vs. 12.07±6.67, P<0.01). The development of pneumonia during hospitalization was higher in non-survivors than in survivors (n=9, 82% vs. n=31, 38%, P<0.01). In multiple logistic regression analysis, serum bicarbonate concentration, APACHE II score, and pneumonia during hospitalization were the important prognostic factors in patients with CI poisoning. Serum bicarbonate and APACHE II score are useful prognostic factors in patients with CI poisoning. Furthermore, pneumonia during hospitalization was also important in predicting prognosis in patients with CI poisoning. Therefore, prevention and active treatment of pneumonia is important in the management of patients with CI poisoning.

To observe and analyze the performance of forensic science in the cases of suxa- methonium chloride poisoning, and to improve the identification of suxamethonium chloride poisoning. Fifty-four cases of suxamethonium chloride poisoning were collected. The rules of determination of suxamethonium chloride poisoning were observed by the retrospective analysis of pathological and toxicological changes as well as case features. The pathological features of suxamethonium chloride poisoning were similar to the general changes of sudden death, which mainly included acute pulmonary congestion and edema, and partly showed myocardial disarray and fracture. Suxamethonium chloride could be detected in the heart blood of all cases and in skin tissue of part cases. Suxa-methonium chloride poisoning has the characteristics with fast death and covert means, which are difficult to rescue and easily miss inspection. For the cases of sudden death or suspicious death, determination of suxamethonium chloride should be taken as a routine detection index to prevent missing inspection.

Histamine (Scombroid) Fish Poisoning: a Comprehensive Review.

PubMed

Feng, Charles; Teuber, Suzanne; Gershwin, M Eric

2016-02-01

Histamine fish poisoning, also known as scombroid poisoning, is the most common cause of ichythyotoxicosis worldwide and results from the ingestion of histamine-contaminated fish in the Scombroidae and Scomberesocidae families, including mackerel, bonito, albacore, and skipjack. This disease was first described in 1799 in Britain and re-emerged in the medical literature in the 1950s when outbreaks were reported in Japan. The symptoms associated with histamine fish poisoning are similar to that of an allergic reaction. In fact, such histamine-induced reactions are often misdiagnosed as IgE-mediated fish allergy. Indeed, histamine fish poisoning is still an underrecognized disease. In this review, we discuss the epidemiology, pathophysiology, evaluation, and treatment of scombroid disease. Because more than 80% of fish consumed in the USA is now imported from other countries, the disease is intimately linked with the global fish trade (National Marine Fisheries Service, 2012). Preventing future scombroid outbreaks will require that fishermen, public health officials, restaurant workers, and medical professionals work together to devise international safety standards and increase awareness of the disease. The implications of scombroid poisoning go far beyond that of fish and have broader implications for the important issues of food safety.
Paracetamol poisoning in children and hepatotoxicity.

1. Paracetamol is one of the most common drugs that children accidentally ingest. Unlike the situation in adults, death and hepatotoxicity in children from paracetamol poisoning are exceedingly uncommon events. A review of the literature has revealed only seven deaths and fourteen cases of hepatotoxicity in children, with most of the cases resulting from chronic poisoning and not acute poisoning. 2. Children may be less prone to paracetamol hepatotoxicity because of developmental differences in the drug's metabolism and its pathways of detoxification. In the therapeutic setting of treatment of fever and pain in children, paracetamol is regarded as a drug with a higher therapeutic index, and as such, there seems to be little concern with strict adherence to dosage regimes. 3. Scrutiny of the above paediatric cases associated with chronic paracetamol poisoning suggests that the margin of safety of frequent therapeutic doses of paracetamol in infants and young children to be a lot lower than previously appreciated. This review highlights the need to re-evaluate the safety of paracetamol in the context of chronic therapy in infants and young children. PMID:1931463

Ciguatera fish poisoning is the most frequently reported seafood toxin illness associated with the ingestion of contaminated tropical fish. Diagnosis relies on a history of recent tropical fish ingestion and subsequent development of gastrointestinal, cardiovascular, and neurological symptoms. Ciguatera poisoning usually has a self-limited time course, and its management involves symptomatic control and supportive care. This case report presents an uncommon case of ciguatera poisoning with prolonged intractable seizures refractory to standard antiseizure medications. The patient also had significant functional decline that responded to rigorous inpatient rehabilitation not previously described in literature.

Local public health departments have a wide array of responsibilities, including coordinating childhood lead poisoning prevention activities. This study was conducted in an effort to understand how local public health officers prioritized lead poisoning prevention activities and the barriers to the delivery of childhood lead poisoning prevention services delivered through local health departments. A telephone survey was conducted of health officers in Michigan, a state with a high burden of environmental lead. Analysis included Spearman rank correlation and Fisher's exact test. No association was found between the local risk of lead poisoning and the priority placed by local health departments on lead poisoning prevention activities. Similarly, there was no association between the local risk of lead poisoning and the availability of services. Only 60% of local health departments offered blood lead testing, environmental investigation, and case management. Most (74%) believed that lead poisoning is inadequately addressed within the area served by their local health department. New strategies of providing lead poisoning prevention activities are needed to achieve the federal and state goals of eliminating childhood lead poisoning over the next decade.
[Poisonings with paracetamol, salicylates and dextromethorphan – problem evaluation based on data from Toxicological Laboratory and Poison Information Center in Krakow in 2010-2015].

The aim of the paper was to study frequency of laboratory determinations and toxicological information related to over-the-counter drugs (OTC): paracetamol (acetaminophen), salicylates and dextromethorphan. The research was based on data from Toxicological Laboratory and Poison Information Center UJ CM in Krakow in years 2010-2015. Paracetamol was determined averagely 102 times a year, more than 50% (57 cases) were positive with confirmation of poisoning. The least number of paracetamol poisoning was noted in 2011 (35 cases), the most were in 2015 (98 cases). In the time span there were averagely 40 salicylates check measurements a year, less than 50% (15 cases) were positive. Dextromethorphane was confirmed averagely in 31 patients a year, decrease of the drug intoxications was noted in 2013-2015. Paracetamol and dextromethorphan were the most often the cause of poisoning in group of patients 13-18 years old, salicylates – more than 30 years. In the group of small children there were only a few poisonings with paracetamol. Toxicological information data related to paracetamol, salicylates and dextromethorphan were similar to data from toxicological laboratory. Mean year numbers of drug poisoning information were: 90 (paracetamol), 14 (salicylates), 30 (dextromethorphan). The differences were in patients age distribution. Acute poisonings with OTC were related mainly to paracetamol, young patients (13- 18 years) and young adults (19-29 years). Salicylates poisoning information were related mainly to the group of adult patients (> 30 years), dextromethorphan was abused mainly by oung patients (13-18 years). There were no observed poisonings with salicylates and dextromethorphan in children, but there were toxicological information about paracetamol and salicylates poisoning and overdose in group of children (1-6 years).

The Extracorporeal Treatments in Poisoning (EXTRIP) Workgroup conducted a systematic literature review using a standardized process to develop evidence-based recommendations on the use of extracorporeal treatment (ECTR) in patients with phenytoin poisoning. The authors reviewed all articles, extracted data, summarized findings, and proposed structured voting statements following a predetermined format. A 2-round modified Delphi method was used to reach a consensus on voting statements, and the RAND/UCLA Appropriateness Method was used to quantify disagreement. 51 articles met the inclusion criteria. Only case reports, case series, and pharmacokinetic studies were identified, yielding a very low quality of evidence. Clinical data from 31 patients and toxicokinetic grading from 46 patients were abstracted. The workgroup concluded that phenytoin is moderately dialyzable (level of evidence = C) despite its high protein binding and made the following recommendations. ECTR would be reasonable in select cases of severe phenytoin poisoning (neutral recommendation, 3D). ECTR is suggested if prolonged coma is present or expected (graded 2D) and it would be reasonable if prolonged incapacitating ataxia is present or expected (graded 3D). If ECTR is used, it should be discontinued when clinical improvement is apparent (graded 1D). The preferred ECTR modality in phenytoin poisoning is intermittent hemodialysis (graded 1D), but hemoperfusion is an acceptable alternative if hemodialysis is not available (graded 1D). In summary, phenytoin appears to be amenable to extracorporeal removal. However, because of the low incidence of irreversible tissue injury or death related to phenytoin poisoning and the relatively limited effect of ECTR on phenytoin removal, the workgroup proposed the use of ECTR only in very select patients with severe phenytoin poisoning.

Objectives. To evaluate the gravity and mortality of those patients admitted to the intensive care unit for poisoning. Also, the applicability and predicted capacity of prognostic scales most frequently used in ICU must be evaluated. Methods. Multicentre study between 2008 and 2013 on all patients admitted for poisoning. Results. The results are from 119 patients. The causes of poisoning were medication, 92 patients (77.3%), caustics, 11 (9.2%), and alcohol, 20 (16,8%). 78.3% attempted suicides. Mean age was 44.42 ± 13.85 years. 72.5% had a Glasgow Coma Scale (GCS) ≤8 points. The ICU mortality was 5.9% and the hospital mortality was 6.7%. The mortality from caustic poisoning was 54.5%, and it was 1.9% for noncaustic poisoning (p < 0.001). After adjusting for SAPS-3 (OR: 1.19 (1.02–1.39)) the mortality of patients who had ingested caustics was far higher than the rest (OR: 560.34 (11.64–26973.83)). There was considerable discrepancy between mortality predicted by SAPS-3 (26.8%) and observed (6.7%) (Hosmer-Lemeshow test: H = 35.10; p < 0.001). The APACHE-II (7,57%) and APACHE-III (8,15%) were no discrepancies. Conclusions. Admission to ICU for poisoning is rare in our country. Medication is the most frequent cause, but mortality of caustic poisoning is higher. APACHE-II and APACHE-III provide adequate predictions about mortality, while SAPS-3 tends to overestimate.

The aim of this study was to assess the mean of histamine concentration in food poisoning. Systematic review and meta-analysis of reports published between 1959 and 2013. Main criteria for inclusion of studies were: all report types that present outbreaks of "histamine poisoning' or "scombroid syndrome" from food, including histamine content and type of food. Health status of people involved must be nonpathological. Fifty-five (55) reports were included, these studies reported 103 incidents. All pooled analyses were based on random effect model; histamine mean concentration in poisoning samples was 1107.21 mg/kg with confidence interval for the meta-mean of 422.62-2900.78 mg/kg; heterogeneity index (I2) was 100% (P < 0.0001); prediction interval was 24.12-50822.78 mg/kg. Fish involved in histamine poisoning was mainly tuna or Istiophoridae species. No clues of association between concomitant conditions (female sex, alcohol consumption, previous medication, and consumption of histamine releasing food) and histamine poisoning, were highlighted. This is the first systematic review and meta-analysis that analyzes all the available data on histamine poisoning outbreaks evaluating the histamine concentration in food involved. Histamine mean concentration in poisoning samples was fairly high. Our study suffers from some limitations, which are intrinsic of the studies included, for instance the lack of a complete anamnesis of each poisoning episode. Protocol registration: Methods were specified in advance and have been published as a protocol in PROSPERO database (18/07/2012 -CRD42012002566).
Organophosphorus poisoning (acute).

PubMed

2007-03-01

Acute organophosphorus poisoning occurs after dermal, respiratory, or oral exposure to either low-volatility pesticides (e.g. chlorpyrifos, dimethoate) or high-volatility nerve gases (e.g. sarin, tabun). Most cases occur in resource-poor countries as a result of occupational or deliberate exposure to organophosphorus pesticides. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute organophosphorus poisoning? We searched: Medline, Embase, The Cochrane Library and other important databases up to August 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 22 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: activated charcoal, alpha2 adrenergic receptor agonists, atropine, benzodiazepines, butyrylcholinesterase replacement therapy, cathartics, extracorporeal clearance, gastric lavage, glycopyrronium bromide, ipecacuanha, magnesium sulphate, milk or other home remedies, N-methyl-D-aspartate receptor antagonists, organophosphorus hydrolases, oximes, sodium bicarbonate, washing the poisoned person and removing contaminated clothing.
Liver histopathology of fatal phosphine poisoning.

Saleki, Sepideh; Ardalan, Farid Azmoudeh; Javidan-Nejad, Abdullah

2007-03-02

Two commonly used pesticides in agriculture are phosphides of aluminium and zinc. Both of these metal phosphides act through elaboration of toxic phosphine gas. The poisoning in Iran is mostly oral and suicidal. Phosphine is rapidly absorbed throughout the gastrointestinal tract after ingestion and it is partly carried to the liver by the portal vein. In this study the liver histopathology of fatal poisoning is scrutinized. A descriptive, retrospective study was performed on 38 fatal phosphine poisonings. The slides of liver specimens of the cases were retrieved and studied separately by two pathologists. The poisoning was suicidal in 33 (86.5%) of cases. Portal inflammation was negligible in 37 cases and only in one of the cases, a moderate degree of chronic inflammation accompanied by granuloma formation was observed. Major histopathologic findings were as follows: mild sinusoidal congestion; 12 cases (31.6%), severe sinusoidal congestion; 25 cases (45.8%), central vein congestion; 23 cases (60.5%), centrilobular necrosis; 3 cases (7.9%), hepatocytes nuclear fragmentation; 6 cases (15.8%), sinusoidal clusters of polymorphonuclear leukocytes; 12 cases (31.6%), and mild macrovesicular steatosis; 5 cases (13.2%). Fine isomorphic cytoplasmic vacuoles were observed in 36 cases (94.7%). These vacuoles were distributed uniformly in all hepatic zones in the majority (75%) of cases. This study reveals that the main histopathologic findings of fatal phosphine poisoning in the liver are fine cytoplasmic vacuolization of hepatocytes and sinusoidal congestion.
[Dieffenbachia poisoning in an infant].

Plant poisoning is becoming an increasingly common reason to consult a doctor. A 7-month-old infant was sent to the emergency room by her general practitioner with a suspected apparent life-threatening event (ALTE). Her parents reported the sudden development of fluctuating restlessness and listlessness, superficial breathing, vomiting, drowsiness and episodes of loss of consciousness. On physical examination we saw a pale, listless and variably responsive girl. During admission for observation, she improved within a few hours, although she had one episode of blood admixture with the stool. After discharge from hospital, the infant's grandmother suggested that the symptoms could be due to poisoning from a Dieffenbachia plant. The literature supports this explanation. Young parents and doctors appear to know little about plant toxicity in general and Dieffenbachia in particular. In small children with poorly-understood symptoms, the possibility plant poisoning should be considered.

This study aimed to investigate the characteristics of pesticide poisoning in Jiangsu Province, China, and to provide a scientific basis for developing effective interventional measures and preventive strategies. From 2006 to 2015, a total of 35,308 cases of pesticide poisoning were reported in Jiangsu Province. Non-occupational poisoning accounted for 73.79% of all poisoning cases. A comparison of the data collected before (2006) and after (2015) this study showed a decrease in non-occupational pesticide poisoning. Pesticide poisoning showed an age central tendency of 30 to 44 years, area central tendency for northern Jiangsu, and seasonal central tendency of occupational pesticide poisoning in autumn. Pesticide poisoning remains a major health concern in China. Government agencies together with scientists should focus their efforts on the prevention of potential threats to vulnerable groups such as the elderly, women, and children.

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 (p<0.001). Organophosphates were the most common cause of poisoning 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.

A pressurized water reactor is described having a core containing Pu/sup 240/ in which the effective microscopic neutronabsorption cross section of Pu/sup 240/ in unconverted condition decreases as the time of operation of the reactor increases, in order to compensate for loss of reactivity resulting from fission product buildup during reactor operation. This means serves to improve the efficiency of the reactor operation by reducing power losses resulting from control rods and burnable poisons. (AEC)

Poisoning is considered a significant health problem in the elderly. This study aimed to portray the pattern of poisoning in the elderly population of Tehran. This cross-sectional study included all patients aged 60 years and older with acute poisoning who attended the emergency department of the Loghman-Hakim hospital over a six-month period (n=299). Episodes of poisoning were more common in men (70.9%) and the majority of incidents took place in the patient's own home (84.3%). Most episodes were accidental (53.2%) followed by attempted suicide (32.4%). Opioids and opiate products accounted for 54.02% of the non-pharmaceutical substances that were involved in episodes of poisoning. Overdose with opioids and opiate products, was higher in male patients than in female patients. The most frequently involved drug groups were benzodiazepines, antidepressants, and analgesics. The most common cause of accidental poisoning was overdose by drug abusers. The Poisoning Severity Score was minor in 25.4%, moderate in 52.2%, and severe in 17.1% of patients. Asymptomatic patients accounted for 5.4% of the total. Unfortunately, 11.7% of patients died. The main agents involved in the fatal cases were opioids and opiate products. The commonest method of accidental poisoning was overdose in opioid and opiate abusers. Attempted suicide was also very common comprising about one third of all cases. The high mortality observed in this study warrants attention to the risk factors and prognostic factors of poisoning in elderly.
Occupational lead poisoning: can it be eliminated?

PubMed

Kaufman, J D; Burt, J; Silverstein, B

1994-11-01

The continued occurrence of occupational lead poisoning and overexposure in the United States represents a serious challenge to the occupational health community. We outline a proposed action strategy which integrates case-based surveillance, hazard surveillance, increased requirements for biological monitoring, and targeted educational activities, with a goal of eliminating occupational lead poisoning. The system provides a simple mechanism for monitoring compliance in lead-using employers, in order to identify employers for enforcement action. Lead poisoning should be viewed as an eradicable condition; successfully solving the persistent lead overexposure problem can serve as a model for approaching other occupational diseases.

Effect of Neutron Absorbers Mixed in or Coating the Fuel of a 1-MWt Lithium-Cooled Space Reactor

DOE Office of Scientific and Technical Information (OSTI.GOV)

Amiri, Benjamin W.; Los Alamos National Laboratory, Los Alamos, NM 87545; Poston, David I.

2005-02-06

The goal of this study was to determine the effect of various neutron poisons (boron, dysprosium, erbium, and gadolinium) on a 1-MWt, lithium-cooled liquid-metal reactor. The isotopes were considered to be in-fuel poisons, as well as poisons coating the fuel. One way to quantify the effectiveness of a poison in meeting accident-condition requirements is by defining the safety margin as the difference between keff at the beginning of life and keff during the accident scenarios. The isotope that showed the most potential in increasing the safety margin for the wet-sand/water case was 157Gd. The safety margin was 10%-20% greater usingmore » 157Gd as an in-fuel poison as opposed to a coating, depending on the poison quantity. However, the most limiting condition (i.e., the accident scenario with the highest keff, thus the lowest safety margin) is when the reactor is submerged in wet sand. None of the isotopes considered significantly affected the safety margin for the dry-sand case. However, the poison isotopes considered may have applicability for meeting the wet-sand/water keff requirements or as burnable poisons in a moderated system. The views expressed in this document are those of the author and do not necessarily reflect agreement by the government.« less
Lead poisoning in children.

Warniment, Crista; Tsang, Katrina; Galazka, Sim S

2010-03-15

The prevalence and severity of childhood lead poisoning have been greatly reduced since the removal of lead from paint and gasoline in the 1970s. Despite these efforts, approximately 310,000 U.S. children younger than five years have elevated blood lead levels. Health care professionals should perform targeted screening for lead poisoning in children who are Medicaid-enrolled or -eligible, foreign born, or identified as high risk by the Centers for Disease Control and Prevention (CDC) location-specific recommendations or by a personal risk questionnaire. Venous sampling is the preferred method for measuring blood lead levels, but a carefully collected finger-stick sample is an acceptable alternative. Capillary samples of elevated levels should be confirmed by a venous sample. The CDC recommends that the threshold for follow-up and intervention of lead poisoning be a blood lead level of 10 microg per dL or higher. Recommendations for treatment of elevated blood levels include a thorough environmental investigation, laboratory testing when appropriate, iron supplementation for iron-deficient children, and chelation therapy for blood lead levels of 45 microg per dL or more. Prevention consists of education and avoidance of lead-contaminated products.

Carbon monoxide is responsible for a large number of accidental domestic poisoning and deaths throughout the world. Domestic carbon monoxide poisoning is rarely reported in India and remains an under recognized problem. The diagnosis of carbon monoxide poisoning is usually based on autopsy findings, circumstantial evidence and estimation of carboxy-haemoglobin in blood. We report a case of fatal accidental carbon monoxide poisoning in a bathroom where an LPG gas water heater was installed recently. Cherry pink discolouration of the body and organs on autopsy suggested carbon monoxide poisoning. Laboratory analysis of blood by UV visible spectrophotometry revealed presence of dangerous levels of carboxy-haemoglobin. Effective preventive measures can help in bringing down the mortality and morbidity associated with carbon monoxide poisoning.

2006-04-01

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.

Fountain, J S; Reith, D M; Holt, A

2014-02-01

To identify poisons information resources most commonly utilized by Australasian Emergency Department staff, and examine attitudes regarding the benefits and user experience of the electronic products used. A survey tool was mailed to six Emergency Departments each in New Zealand and Australia to be answered by medical and nursing staff. Eighty six (71.7%) responses were received from the 120 survey forms sent: 70 (81%) responders were medical staff, the remainder nursing. Electronic resources were the most accessed poisons information resource in New Zealand; Australians preferring discussion with a colleague; Poisons Information Centers were the least utilized resource in both countries. With regard to electronic resources, further differences were recognized between countries in: ease of access, ease of use, quality of information and quantity of information, with New Zealand better in all four themes. New Zealand ED staff favored electronic poisons information resources while Australians preferred discussion with a colleague. That Poisons Information Centers were the least utilized resource was surprising. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.
Effect of catalysts on dc corona discharge poisoning

NASA Astrophysics Data System (ADS)

Pekárek, S.

2011-02-01

The processes of ozone generation in non-thermal plasma produced by an electrical discharge in air at atmospheric pressure are burdened by the presence of nitrogen oxides, which on the one hand contribute to ozone generation and on the other hand are responsible for unpleasant discharge poisoning. The term discharge poisoning refers to the situation when the discharge ozone formation completely breaks down. Discharge poisoning can be affected by placing a catalyst in the discharge chamber. For the dc hollow needle to mesh corona discharge enhanced by the flow of air through the needle electrode we studied the effect of titanium dioxide TiO2, ZSM-5 zeolite or Cu++ZSM-5 zeolite on discharge poisoning by monitoring the ozone, nitrogen monoxide and nitrogen dioxide discharge production. We found that placing globules of any of these catalysts on the mesh decreases the energy density of the onset of discharge poisoning, and this energy density is smallest for a discharge with globules of a TiO2 on the mesh.

Acute poisoning is a frequent accident in childhood, particularly in children under 4 years of age. This was a descriptive study with data collected from standardized forms of the Poison Control Center and patient record charts. All the cases of acute poisoning in children aged 0 to 14 years during the period 2008 to 2012 were selected. The variables studied comprised characteristics of the events and toxic agents, clinical development, and outcome. A total of 657 cases of acute poisoning, with higher frequency in the age-group from 1 to 4 years (48.7%) and male sex (53.4%), were recorded. The occurrences were accidental in 92% of the cases, and 5.8% were due to suicide attempts. Among the toxic agents, medications (28.5%), venomous animals (19.3%), nonvenomous animals (10%), household cleaning products (9.0%), and raticide agents (8.7%) predominated. The majority of cases were characterized as light (73.5%) and around 18% required hospitalization, and there was low lethality (0.5%). PMID:27335994

To provide an overview of the clinical presentation, diagnosis, management, and treatment with advanced practice nursing implications of black-spot poison ivy phenomenon. Case presentation and comprehensive literature review on black-spot poison ivy. Black-spot poison ivy is a rare phenomenon and usually poses a diagnostic challenge. It usually presents after exposure to a higher concentration of uroshiol on Toxicodendron plants. Patients present with black-spot deposits on the epidermis with underlying poison ivy dermatitis. The black deposits cannot be washed off the skin and are followed by itchy blisters. They eventually peel off and the skin heals without scarring. An understanding of the pathophysiology, clinical presentation, treatment, and management of this rare phenomenon is important for the nurse practitioner (NP) to be able to make an accurate diagnosis and initiate appropriate treatment without delay. The NP's recognition and differentiation of it from other skin disorders including melanoma is paramount. ©2011 The Author(s) Journal compilation ©2011 American Academy of Nurse Practitioners.
Education of young children concerning poison prevention.

Butts, J D; Beck, C L

1986-01-01

Every year about 5,000 fatal accidental poisonings occur in the United States. About 50 percent of those who die are children under the age of 5 years. Medications, house plants, and household cleaning agents are the three leading causes of accidental poisonings in this age range. Since there is an always changing population of children under the age of 5 years, there is a continuing need for education. A committee of the Student American Kentucky Pharmaceutical Association decided to become actively involved in filling the need for education by writing and performing a poison prevention puppet play. The 10-minute play is suitable for small volunteer organizations. It requires only a small financial outlay, and two persons with minimal training can present the play. The play has been shown to more than 6,000 youngsters in the past 2 years. Responses to followup surveys of both the teachers and the students have shown a positive effect on the children's attitudes toward poison prevention.
Scombroid poisoning: mini-review with case histories.

PubMed

Russell, F E; Maretić, Z

1986-01-01

Scombroid poisoning has become an almost world-wide medical problem. It is probably the most common cause of fish poisoning, although frequently misdiagnosed as "Salmonella infection'. While there remains some question as to the definitive etiology, there is little doubt that the poisoning is caused by the ingestion of certain mackerel-like fishes whose tissues have undergone a number of changes provoked by bacteria, and involving the conversion of histidine to histamine, potentiated by diamines. Improper storage of the fishes, usually at temperatures above 20 degrees C, appears to be the most important predisposing factor. The organisms most commonly involved are Proteus sp., Clostridium sp., Escherichia sp., Salmonella sp. and Shigella sp. Twenty-five cases of scombroid poisoning are presented. The clinical manifestations were very similar in most cases, consisting of: alterations in taste; anxiety; hyperemia, particularly of the face and neck; nausea; pruritus; headache; certain other symptoms and signs. Most patients responded to antihistamitics, and all cases were self-limiting.
Lead poisoning in a Mississippi sandhill crane

Lead poisoning from the ingestion of spent lead shot is well documented in waterfowl (Sanderson and Bellrose 1986) and has been reported in other wetland (Locke et al. 1991, Windingstad et al. 1984) and upland (Hunter and Rosen 1965, Locke and Bagley 1967) avian species. Ingested fishing weights have been implicated in lead poisoning of Trumpeter Swans (Cygnus buccinator) (Blus et al. 1989), Common Loons (Gavia immer) (Locke et al. 1982, Franson and Cliplef 1992, Pokras and Chafe1 1992), Mute Swans (Cygnus olor) (Birkhead 1982), and Sandhill Cranes (Grus canadensis) (Windingstad et al. 1984). The significance of lead poisoning as a mortality factor in avian species other than waterfowl is probably underestimated (Locke and Friend 1992), and any cause of mortality becomes particularly important in species with small population sizes. We report here the first known case of lead poisoning in a Mississippi Sandhill Crane (Grus canadensis pulla), a critically endangered subspecies.
Acute abdominal pain and constipation due to lead poisoning.

Mongolu, S; Sharp, P

2013-01-01

Although uncommon, lead poisoning should be considered as a differential diagnosis in cases of unexplained acute abdominal pain in both adults and children. We present the case of a 35-year-old Asian male who presented with abdominal pain and constipation secondary to lead poisoning. Initially, the source of lead exposure was not apparent; this was later found to be due to ingestion of an Ayurvedic herbal medicine for the treatment of infertility. Lead poisoning due to the ingestion of Ayurvedic remedies is well described. We discuss the diagnosis, pathophysiology and treatment of lead poisoning. This case illustrates one of the rarer medical causes of acute abdominal pain and emphasizes the need to take a thorough history (including specific questioning regarding the use of over-the-counter and traditional/ herbal remedies) in cases of suspected poisoning or drug toxicity.

The aim of the study was to evaluate carbohydrate metabolism in patients hospitalised because of acute intoxication with xenobiotics. An analysis of 3628 patients (1553 females and 2075 males; age: 40.6 +/- 15.9 y) hospitalized at the Ward of Toxicology and Environmental Diseases because of acute poisoning in 2004-2006 was done. The patients with diabetes mellitus diagnosed prior to hospitalisation were excluded from the analysis. The blood ethanol concentration was measured, medication drugs and/or psychoactive substance screening test were performed in all patients on admission. Fasting glucose level on admission and control level on second or third day of hospitalisation were determined. Risk ratio of hyperglycaemia according to toxic agent was assessed using multiple regression model considering age, gender, and the patient education. In 18.2% (398 males and 254 females) of the patients the blood glucose level on admission was > or = 7.8 mmol/l; in u 3.6% (78 males and 50 females) > or = 11.1 mmol/l. In 24 (0.6%) of the patients glycaemia on admission was < or = 3.5 mmol/l. Control fasting glucose level of > or = 7.0 mmol/l was determined in 115 males and 76 female patients. 42% elevation in risk of hyperglycaemia was noted in acute carbon monoxide poisoning (OR = 1.42; 95% PU: 1.11-1.82). In ethanol intoxicated patients 12% drop in risk of hyperglycaemia was noted (OR = 0.88; 95% PU: 0.72-1.07). Benzodiazepine poisoning diminished risk of hyperglycaemia in 36% (OR=0.64; 95%PU: 0.48-0.84). Risk of hyperglycaemia in poisoning by medicines co-ingested with ethanol was always lower compared to poisoning with the single agent. A higher risk of hyperglycaemia was related to acute carbon monoxide poisoning whereas lower risk of hyperglycaemia was attributed to benzodiazepines and alcohol. A frequency of hypoglycaemia in the group of poisoned patients was much more lower compared to hyperglycaemia.

Organophosphate poisoning is a major public health problem in South Africa. Individuals get exposed to organophosphate in both the domestic and industrial spheres. A cross-sectional study was conducted using retrospective, secondary data of organophosphate poisoning cases over a 3-year period, reported at the Tshwane District surveillance office. Data were analysed using Microsoft Excel, and Epi Info version 7 was used for descriptive statistics. A total of 207 cases were reported with ages ranging from 10 months to 59 years. Most of the cases were men (58.9%). Intentional poisoning accounted for 51% of cases. Unintentional poisoning accounted for 21.7% of cases, and 26.5% of cases had unknown circumstances of poisoning. A significant number (50.2%) of intentional poisonings were suicide related. Nonsuicidal cases accounted for 47.4% of cases, and deliberate unlawful poisoning accounted for 2.4% of cases. The mortality rate for the whole group was 3.4%. Improvement in data collection on organophosphate poisoning is essential to properly measure the burden of the problem. More effective regulatory controls for pesticide use are needed in South Africa.

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.
Rabbitfish ("aras"): an unusual source of ciguatera poisoning.

Ciguatera poisoning is the commonest fish-borne seafood intoxication. It is endemic to warm water tropical areas and is caused by consumption of bottom-dwelling shore reef fish, mostly during spring and summer. The causative agent, ciguatoxin, is a heat-stable ester complex that becomes concentrated in fish feeding on toxic dinoflagellates. The common clinical manifestations are a combination of gastrointestinal and neurologic symptoms. Severe poisoning may be associated with seizures and respiratory paralysis. To describe a series of patients who sustained ciguatera poisoning in an uncommon region and from an unexpected source. Two families complained of a sensation of "electrical currents," tremors, muscle cramps, nightmares, hallucinations, agitation, anxiety and nausea of varying severity several hours after consuming rabbitfish ("aras"). These symptoms lasted between 12 and 30 hours and resolved completely. The temporal relationship to a summer fish meal, the typical clinical manifestations along with the known feeding pattern of the rabbitfish suggested ciguatera poisoning. The Eastern Mediterranean basin is an unusual region and the rabbitfish an unusual source for ciguatera poisoning. There are no readily available and reliable means for detecting ciguatoxin in humans. A high index of suspicion is needed for diagnosis and a thorough differential diagnosis is essential to eliminate other poisonings, decompression sickness and encephalitis. Supportive therapy is the mainstay of treatment.

Experience with soluble neutron poisons for criticality control at ICPP

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wilson, R.E.; Mortimer, S.R.

1978-01-01

Soluble neutron poisons assure criticality control in two of the headend fuel reprocessing systems at the Idaho Chemical Processing Plant. Soluble poisons have been used successfully since 1964 and will be employed in the projected new headend processes. The use of soluble poisons (1) greatly increases the process output (2) allows versatility in the size of fuel assemblies processed and (3) allows the practical reprocessing of some fuels. The safety limit for all fluids entering the U-Zr alloy dissolver is 3.6 g/liter boron. To allow for possible deviations in the measurement systems and drift between analytical sampling periods, the standardmore » practice is to use 3.85 g/liter boron as the lower limit. This dissolver has had 4000 successful hours of operation using soluble poisons. The electrolytic dissolution process depends on soluble gadolinium for criticality safety. This system is used to process high enriched uranium clad in stainless steel. Electrolytic dissolution takes advantage of the anodic corrosion that occurs when a large electrical current is passed through the fuel elements in a corrosive environment. Three control methods are used on each headend system. First, the poison is mixed according to standard operating procedures and the measurements are affirmed by the operator's supervisor. Second, the poisoned solution is stirred, sampled, analyzed, and the analysis reported while still in the mix tank. Finally, a Nuclear Poison Detection System (NPDS) must show an acceptable poison concentration before the solution can be transferred. The major disadvantage of using soluble poisons is the need for very sophisticated control systems and procedures, which require extensive checkout. The need for a poisoned primary heating and cooling system means a secondary system is needed as well. Experience has shown, however, that production enhancement more than makes up for the problems.« less

To estimate the mortality rate due to occupational pesticide poisoning in Brazil. Data on diagnoses of death from pesticide poisoning between 2000 and 2009 were obtained from the Mortality Information System. ICD-10 codes T60.0-T60.4, T60.8 and T60.9, Y18, X487 and Z578 as the main or secondary cause of death; data on work-related deaths were obtained from the death certificate, from the fields , and whether cases were agricultural workers. Homicides and suicides were excluded. To calculate mortality, the number of agricultural workers was obtained from the Brazilian Institute of Geography and Statistics, National System of Accounts estimates. There were 2,052 deaths recorded as caused by pesticide poisoning in Brazil, between 2000 and 2009, of which 36.2% (n = 743) had no occupation data. Of the remaining 1,309, 679 (51.9%) were agricultural workers. Mortality from occupational pesticide poisoning declined from 0.56/100.000 (2000-2001) to 0.39/100.000 (2008-2009) workers during the study period, and there was a larger decrease among men compared with women. Males had a higher mortality from this type of poisoning than women in all study years. Most deaths were caused by organophosphates and carbamate pesticides poisoning. During the study period the number of cases declined in all regions, except for the Northeast. Improvement in the quality of Death Certificate records is needed, particularly for occupation and the assessment of causes of death as work related, crucial for work injuries control and prevention programs. Special attention is required in the Northeast region.
Scombroid-type poisoning induced by the ingestion of smoked kahawai.

PubMed

Foo, L Y

1975-05-28

Three incidents of presumptive scombroid poisoning were reported in the Wellington area in 1973. Two of these cases were attributed to canned mackerel and the third to smoked kahawai. The marked similarity of the symptoms of the kahawai poisoning to those of the other two outbreaks of scombroid fish poisoning and the relief following anti-histamine therapy suggests that the poisoning arose from a similar source. Analysis of the extracts from the smoked kahawai revealed an abnormally high level of histamine and the presence of an unknown toxin. The unknown substance resembled saurine, the toxin that has been incriminated in scromboid poisoning, thus suggesting that scombroid intoxication may not be confined to fish belonging to the sub-order Scombroidei.

Minimal physical requirements for crystal growth self-poisoning

DOE PAGES

Whitelam, Stephen; Dahal, Yuba Raj; Schmit, Jeremy D.

2016-02-10

Self-poisoning is a kinetic trap that can impair or prevent crystal growth in a wide variety of physical settings. In this paper, we use dynamic mean-field theory and computer simulation to argue that poisoning is ubiquitous because its emergence requires only the notion that a molecule can bind in two (or more) ways to a crystal; that those ways are not energetically equivalent; and that the associated binding events occur with sufficiently unequal probability. If these conditions are met then the steady-state growth rate is in general a non-monotonic function of the thermodynamic driving force for crystal growth, which ismore » the characteristic of poisoning. Finally, our results also indicate that relatively small changes of system parameters could be used to induce recovery from poisoning.« less

To investigate the toxin characteristics of toxins in patients of acute poisoning in the Guangxi area. A retrospective study was conducted. The data of acute poisoning cases and the causative toxins collected from 63 hospitals of Guangxi, including 36 city hospitals, 12 county hospitals, and 15 township health centers from January 2005 to December 2009 were collected. The data were descriptively analyzed and classified by year. A total of 6005 cases with acute poisoning induced by 532 kinds of poisons were enrolled. The 532 kinds of toxin were classified by high-occurrence (producing poisoning for 5 continuous years), low-occurrence (leading to poisoning for 2-4 continuous years) and newly occurred categories (leading to poisoning only in 1 year). The numbers of poisons of these 3 categories accounted for 10.15% (54 kinds), 29.70% (158 kinds), 60.15% (320 kinds) of total number of poisons, respectively. There were 4688 (78.07%), 780 (12.99%), and 537 (8.94%) cases for each category respectively. And the poisoning cases of each toxin involved from 8 to 837, 2 to 25, and 1 to 69 cases respectively. 77.78% (42/54) of high-occurrence poisons affect more than 20 cases, and 89.87% (142/158), 98.75% (316/320) of low-occurrence and new-occurrence poisons involved less than 10 cases. In the dynamic analyses for 5 years, frequency of toxin caused by high-occurrence, low-occurrence and newly occurred poisons in 5 years were 5 times, 2.6 times, and 1 time, respectively. The number of poisons caused by the high-occurrence toxin each year were same, but the average-annual growth rates of poison numbers caused by the low-occurrence and new-occurrence poisons each year were 17.61% and 20.10%. The average-annual growth rates of poisoning cases caused by the 3 categories of poisons were 14.08%, 16.53%, 31.96%, and the average-annual growth rates of poisoning cases caused by each categories were 10.28%, 1.13%, 11.45%, respectively.

To seek the characteristics of pesticide poisoning in emergency departments. Twenty-five hospitals were selected. Among them, they were 14 province or city level and 11 county level. The object of study was the patients with pesticide poisoning who were first visit to a doctor (including transfer to the above emergency departments of hospitals) from July 1, 2001 to June 30, 2002. There were 2 261 cases of pesticide poisoning that ranked third place of total acute poisoning cases at the same period. Gender ratio was 1 male to 1.47 female. Among 1 618 patients who first visited to emergency departments (excluding transfer), 43.9% were by emergency ambulance. 68.3% of total cases were caused by intentional exposure to pesticides, of which female accounted for 75.8%. Young people aged 15 to approximately 34 years accounted for 47.5% of all cases. Children (0 to approximately 14 years) also had relatively high pesticide poisoning rates, particularly an accident pesticide poisoning for 1- to approximately 4-year-old children accounted for 65.9% of total acute poisoning in the age group. 98.2% of all cases needed urgent medical treatment, and 52.4% were hospitalized. The leading occupation of patients was farmers followed by housekeepers, students and preschoolers. Insecticides poisoning accounted for 60.1% of all pesticides. The fatality rate in emergency department was 3.9%. 60.8% case was collected from county hospital. Pesticide poisoning rank first place of total acute poisoning cases in county hospital.

Alcohol use disorders are frequently associated with self-intoxication in attempted suicide. In France since 2008, the off-label use of baclofen for treatment of alcohol dependence has greatly increased, leading to temporary regulation of use of the drug. At the request of the national authorities, the French Poison Control Centers carried out a retrospective survey to give an overview of baclofen exposure in this population. A retrospective study was carried out from January 2008 to December 2013, focusing on baclofen exposures in alcohol-dependent patients managed by the nine national French Poison Control Centers. 294 observations of baclofen exposures in alcohol-dependent patients were identified in our database. Of these, 220 were suicide attempts by self-poisoning and 74 were unintentional. The mean age of patients was 41.7 years, with a sex-ratio of 1.6. Patients attempting suicide with baclofen were younger than those with unintentional exposures, and 43.6% of them were women (vs 22.9%, p < 0.01). The mean supposed ingested dose was higher (480.7 mg) in patients who attempted suicide (vs 192.5 mg, p < 0.0001). 21.8% of intentional exposures involved baclofen alone. Psychiatric comorbidity (50.4%) was more frequent in the group of self-poisoning (p < 0.001). 132 patients were coded as severely exposed (60.0%). Nine victims died, but the causal link between self-poisoning with baclofen and fatal outcome should be interpreted with particular caution. Baclofen self-poisoning by alcohol-dependent patients is a serious concern for the French health authorities. Our results are similar to those previously published, suggesting that most patients with baclofen overdose should be admitted to an intermediate or intensive care unit as the clinical course requires close monitoring. Because suicidal ideation and suicide attempts are more prevalent in people with substance use disorders than in the general population, and because of the lack of

To provide scientific evidence of making measures for prevention of pesticide poisoning, the investigation on the condition of pesticides poisoning was carried out in Wuhan. Registration data of pesticide poisoning from 2002 to 2010 in Wuhan were collected and statistically analyzed by SAS 9.1. During the nine years, there were 4713 cases reported for pesticide poisoning. Among them, the number of occupational poisoning was 2737 (2 cases died), with fatality rate of 0.07%. The number of non-occupational poisoning was 1976 (159 cases died), and its fatality rate was 8.05%. The incidence of occupational poisoning and non-occupational poisoning accounted for 58.1% and 41.9%, respectively. Insecticides especially organophosphorus insecticides, such as parathion, dichlorvos, and methamidophos accounted for 70.6% of the poisoning. Occupational poisoning took place mainly in man, accounting for 68.8%, Non-occupational or life poisoning in contrast mainly occurred in women with a proportion of 66.8%. The majority of the occupational poisoning were 30-59 year-old patients (2239 cases, 81.8%). The majority of the non-occupational poisoning were 30-44 year-old patients (665 cases, 33.6%) and - 70 years old patients (209 cases, 10.6%). High incidence of occupational pesticide poisoning, the regional distribution of Caidian (1016 cases, 37.1% ) highest, followed by the Dongxihu, Hannan and Huangpi. The pesticide poisoning mainly occurred from July to September. The occupational poisoning was mainly caused by poor protection, long working hours, and practice not implemented. The non-occupational poisoning was mainly caused by suicide. The majority of the occupational poisoning in Wuhan was middle-aged men. The pesticide poisoning was main caused by insecticides.

Many partially sighted children use the mouth, lips, and tongue as an aid in identifying objects—this has been termed discriminatory pica. Investigation of a case of lead poisoning in a pupil at a residential school for the blind led to the discovery of others with asymptomatic lead poisoning, all of whom had the same habit. All the children recovered without treatment when they abandoned their habit of discrimination by use of the mouth. Authorities responsible for schools for the blind should be aware of this risk.

Nonequilibrium quasiparticles represent a significant source of decoherence in superconducting quantum circuits. Here we investigate the mechanism of quasiparticle poisoning in devices subjected to local quasiparticle injection. We find that quasiparticle poisoning is dominated by the propagation of pair-breaking phonons across the chip. We characterize the energy dependence of the time scale for quasiparticle poisoning. Finally, we observe that incorporation of extensive normal metal quasiparticle traps leads to a more than order-of-magnitude reduction in quasiparticle loss for a given injected quasiparticle power.

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.

Objective: To analyze the characteristics of acute pesticide poisoning in Ningbo, and to provide scientific basis for the prevention and control strategy. Methods: In February 2017, the pesticide poisoning report card of Ningbo from 2011 to 2016 was drawn from the China Disease Control and prevention information system. The data of the report card was organized by Excel and analyzed by SPSS19.0 software. Results: 2593 cases of acute pesticide poisoning were reported in Ningbo from 2011 to 2016, 125 deaths, and the case fatality rate was 4.82%. The productive pesticide poisoning and unproductive pesticide poisoning were 299 and 2294, respectively, the ratio was 1: 7.67. The case fatality rate were 0.33% and 5.41%, respectively. The difference was statistically significant (χ(2)=14.83, P<0.01). The productive Pesticide poisoning mainly occurred from July to September (55.85%) , the unproductive pesticides mainly occurred from April to June (30.64%) and July to September (30.34%). The seasonal distribution of the pesticide poisoning in the two groups was statistically significant (χ2=82.21, P<0.01). The productive pesticide poisoning in male (80.27%) was significantly higher than the proportion of unproductive pesticide poisoning (52.09%) , the differences in gender composition between the two types of pesticide poisoning was significant (χ2=84.97, P<0.01). The productive pesticide poisoning from 55 to 65 years old group was in the largest number (35.45%) , and the distribution of unproductive pesticide poisoning was uniform in each age group including 25 years old and above, the difference in age composition between two types of pesticide poisoning was statistically significant (χ2=177.84, P<0.01). All of the 10 counties of Ningbo had reports of pesticide poisoning. The counties with more reports were Ninghai county (18.28%) , Fenghua district (14.69%) and Yuyao (12.42%).

The process gas released from the fuel pellets of uranium fuel during fuel burn-up reduces the thermal conductivity of the rod-shell gap, enhances hydrogen embrittlement of the cladding material, causes it's carbonization, as well as transport processes in the fuel. In this study a technique of investigating the thermal desorption of gases from the UO2 fuel material were perfected in the temperature range 300-2000 K for uniform sample heating rate of 15 K/min in vacuum. The characteristic kinetic dependences are acquired for the gas emission from UO2 samples, containing simulators of fission products (SFP) and the burnable neutron absorber (BNA). Depending on the amount of SFP and BNA contained in the sample thermal desorption gas spectra (TDGS) vary. The composition of emitted gas varies, as well as the number of peaks in the TDGS and the peaks shift to higher temperatures. This indicates that introduction of SFPs and BNA alters the sample material structure and cause the creation of so- called traps which have different bonding energies to the gases. The traps can be a grid of dislocations, voids, and contained in the UO2 matrix SFP and BNA. Similar processes will occur in the fuel pellets in the real conditions of the Nuclear Power Plant as well.

All children aged under 15 years admitted to hospital in Newcastle upon Tyne between 1974 and 1981 with a diagnosis of poisoning were studied. After the introduction in 1976 of child resistant containers for salicylates and paracetamol, salicylate poisonings fell dramatically. The other most important medicines to cause poisoning in young children were tricyclic antidepressants, benzodiazapines, Lomotil (diphenoxylate and atropine), and iron preparations; these should also be packaged in child resistant containers by regulation. Few children had symptoms after poisoning with household products, but bleach, turpentine, and paraffin might also be packaged in child resistant containers. The numbers of adolescent girls admitted after deliberate self poisoning and of teenage boys admitted after ingestion of alcohol increased over the study period. PMID:6134564
Poisoning by Herbs and Plants: Rapid Toxidromic Classification and Diagnosis.

PubMed

Diaz, James H

2016-03-01

The American Association of Poison Control Centers has continued to report approximately 50,000 telephone calls or 8% of incoming calls annually related to plant exposures, mostly in children. Although the frequency of plant ingestions in children is related to the presence of popular species in households, adolescents may experiment with hallucinogenic plants; and trekkers and foragers may misidentify poisonous plants as edible. Since plant exposures have continued at a constant rate, the objectives of this review were (1) to review the epidemiology of plant poisonings; and (2) to propose a rapid toxidromic classification system for highly toxic plant ingestions for field use by first responders in comparison to current classification systems. Internet search engines were queried to identify and select peer-reviewed articles on plant poisonings using the key words in order to classify plant poisonings into four specific toxidromes: cardiotoxic, neurotoxic, cytotoxic, and gastrointestinal-hepatotoxic. A simple toxidromic classification system of plant poisonings may permit rapid diagnoses of highly toxic versus less toxic and nontoxic plant ingestions both in households and outdoors; direct earlier management of potentially serious poisonings; and reduce costly inpatient evaluations for inconsequential plant ingestions. The current textbook classification schemes for plant poisonings were complex in comparison to the rapid classification system; and were based on chemical nomenclatures and pharmacological effects, and not on clearly presenting toxidromes. Validation of the rapid toxidromic classification system as compared to existing chemical classification systems for plant poisonings will require future adoption and implementation of the toxidromic system by its intended users.

Warnings unheeded: a history of child lead poisoning.

Child lead poisoning has been a major public health issue only for the last 20-25 years. However, awareness that lead-based paint is a source of lead poisoning in children dates back to the first few years of the twentieth century. Articles in medical journals and textbooks appeared in the United States and elsewhere, recounting cases of children poisoned by the lead paint in their homes on woodwork, baby cribs, and other furniture. The number of positively diagnosed cases was limited both by the imprecision of diagnostic tools and physicians' lack of familiarity with the signs and symptoms of plumbism in children. Nevertheless, a number of hospitals and at least one large city health department recorded numerous cases of child lead poisoning in the 1920s and 1930s. The mounting evidence in those years made it clear that child lead poisoning was a serious public health hazard. And the activities and statements of the lead industry's representatives left little doubt that they were aware of the dangers of lead paint. Nevertheless, the lead paint companies continued to manufacture and sell their product well past 1940. Images FIGURE 1 PMID:2683817

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.

To compare cases of poisoning according to age to detect differences in frequency of visits to the emergency department, patient characteristics, case management, and immediate outcome in terms of related mortality. Descriptive study of a retrospective series of patients who visited a university hospital emergency department for treatment of poisoning between 2009 and 2014. We collected patient characteristics and data related to the event, case management, and poisoning-related death. Patients were grouped according to age (cut-off 65 y). Of a total of 3847 poisoning episodes, 341 (8.9%) were in patients aged 65 years or older. The percentage of women among these older patients (61.3%) was greater than among younger patients (36.3%; P<.001). Poisoning was accidental in older patients more often than younger ones (64.4% vs 9.5%, respectively; P<.001), occurred more often in the home (82.1% vs 37%, P<.001), and more often required active treatment (73.3% vs 57.4%; P<.001) and admission to hospital (21.4% vs 7.3%, P<.001). The related mortality rate was also higher in the older patients (2.1% vs 0.1% in younger patients, P<.001). The percentage of poisonings in patients aged 65 years or older is not negligible. Poisoning in patients of advanced age tends to be accidental and take place in the home. Older patients more often require active treatment and hospital admission; poisoning-related death is more common in older patients than younger ones.

Objectives. Carbon monoxide (CO) poisoning is a leading cause of morbidity and mortality during natural disasters. On January 26–27, 2009, a severe ice storm occurred in Kentucky, causing widespread, extended power outages and disrupting transportation and communications. After the storm, CO poisonings were reported throughout the state. The objectives of this investigation were to determine the extent of the problem, identify sources of CO poisoning, characterize cases, make recommendations to reduce morbidity and mortality, and develop prevention strategies. Methods. We obtained data from the Kentucky Regional Poison Center (KRPC), hyperbaric oxygen treatment (HBOT) facilities, and coroners. Additionally, the Kentucky Department for Public Health provided statewide emergency department (ED) and hospitalization data. Results. During the two weeks after the storm, KRPC identified 144 cases of CO poisoning; exposure sources included kerosene heaters, generators, and propane heaters. Hospitals reported 202 ED visits and 26 admissions. Twenty-eight people received HBOT. Ten deaths were attributed to CO poisoning, eight of which were related to inappropriate generator location. Higher rates of CO poisoning were reported in areas with the most ice accumulation. Conclusions. Although CO poisonings are preventable, they continue to occur in postdisaster situations. Recommendations include encouraging use of CO alarms, exploring use of engineering controls on generators to decrease CO exposure, providing specific information regarding safe use and placement of CO-producing devices, and using multiple communication methods to reach people without electricity.

Gadolinia is utilized in light water power reactors as burnable poison for reserving excess reactivity. Good gadolinia worth estimation is useful for evaluating fuel bundle designs, core operating strategies, and fuel cycle economics. The authors have developed an improved perturbation method based on exact perturbation theory for gadolinia worth calculations in fuel bundles. The method predicts much more accurate gadolinia worth than the first-order perturbation method (commonly used to estimate nuclide worths) for bundles containing fresh or partly burned gadolinia.

The objective of this study is to estimate the numbers and rate of emergency department visits in South Korea that are the result of pesticide poisoning and to describe their epidemiologic characteristics. Data collected from the National Emergency Department Information System were used to estimate the number of emergency department visits due to pesticide poisoning in South Korea for the period spanning 2006 through 2009. Emergency department visits for pesticide poisoning were defined by ICD-10 codes (T60.0-T60.9). National estimates and their 95% confidence intervals were calculated per 100 000 population. Among the 65 877 total poisoning-related emergency department visits in the data, 11 985 (18.2%) were emergency department visits resulting from pesticide poisoning. During the study period, the annual average rate of emergency department visits for pesticide poisoning was 26.8 per 100 000 population. Intentional pesticide poisoning (51.4%) was more frequent than unintentional. The fatality rate from intentional pesticide poisoning was also higher than that from unintentional or cases where the intention was unknown. In terms of age-specific rates of emergency department visits for pesticide poisoning, they increased with age, as did the gap between men and women. This study provide estimates for emergency department visits due to pesticide poisoning at the national level and suggests that pesticide poisonings, both intentional and unintentional, require significant public health interventions in South Korea.

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

Every year about 5,000 fatal accidental poisonings occur in the United States. About 50 percent of those who die are children under the age of 5 years. Medications, house plants, and household cleaning agents are the three leading causes of accidental poisonings in this age range. Since there is an always changing population of children under the age of 5 years, there is a continuing need for education. A committee of the Student American Kentucky Pharmaceutical Association decided to become actively involved in filling the need for education by writing and performing a poison prevention puppet play. The 10-minute play is suitable for small volunteer organizations. It requires only a small financial outlay, and two persons with minimal training can present the play. The play has been shown to more than 6,000 youngsters in the past 2 years. Responses to followup surveys of both the teachers and the students have shown a positive effect on the children's attitudes toward poison prevention. Images p92-a PMID:3080798
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.

Vetter, J

2004-09-01

One of the most poisonous species amongst higher plants is Conium maculatum. It is a very common nitrophile weed species, belonging to the Apiaceae (formerly Umbelliferae) family. It contains some piperidine alkaloids (coniine, N-methyl-coniine, conhydrine, pseudoconhydrine, gamma-coniceine), which are formed by the cyclisation of an eight-carbon chain derived from four acetate units. gamma-Coniceine is the precursor of the other hemlock alkaloids. All vegetative organs, flowers and fruits contain alkaloids. The concentrations (both absolute and relative) of the different alkaloids depend on plant varieties, on ecological conditions and on the age of the plant. The characteristic biological effects of the plants are summarised on cattle, sheep, goat, swine, rabbit, elk, birds and insects and the symptoms of the human toxicosis (some cases of poisonings) are discussed according to the literature data. The general symptoms of hemlock poisoning are effects on nervous system (stimulation followed by paralysis of motor nerve endings and CNS stimulation and later depression), vomiting, trembling, problems in movement, slow and weak later rapid pulse, rapid respiration, salivation, urination, nausea, convulsions, coma and death.

Background propanil pesticide poisoning can produce methaemoglobinaemia, tissue hypoxia, and depression of CNS and respiratory system. It has been recorded only rarely worldwide and most current poison texts consider propanil to be of low toxicity. However, propanil self-poisoning is a significant clinical problem in parts of Sri Lanka and a not uncommon cause of death. Aim of study to report the clinical features and management of severe propanil poisoning. Patients and Methods we report a retrospective case series of patients who were treated in the intensive care unit (ICU) of and/or died in Anuradhapura General Hospital between 1998 and early 2002. Results sixteen patients were identified. Common manifestations of toxicity included confusion, reduced conscious level, cyanosis, and respiratory depression. Marked haemolysis was noted in several patients. Nine deaths occurred due to respiratory depression and cardiorespiratory arrest. Management was difficult given the lack of IV methylene blue, inability to measure methaemoglobin levels, and paucity of ICU beds. Conclusions this series indicates that propanil poisoning can be a severe form of self-poisoning, particularly in resource-poor settings. We have now initiated the establishment of a prospective series of propanil poisoned patients to further describe its clinical features, responsiveness to therapy, and case fatality rate.

The development of contact sensitivity to poison ivy urushiol in Hartley guinea pigs was inhibited by i.v. injection of the diacetate esters of poison ivy and oak urushiols into guinea pigs 2 weeks prior to attempted sensitization with homologous antigen. Immune tolerance to urushiols of poison ivy and oak developed in 80% or more of the treated animals and persisted for the duration of the study, 8 weeks. The tolerance was immunologically specific for urushiols since the tolerant animals were sensitizable to the unrelated sensitizer 2, 4-dinitrochlorobenzene. Guinea pigs already sensitive to urushiol were also desensitized or hyposensitizied by i.v. injection of urushiol acetates in successively increasing doses. After receiving the equivalent of 16 mg of poison ivy and oak urushiols in the acetate form over a period of 12 weeks, 54% of a group of guinea pigs were desensitized to poison ivy. all of the remaining 46% of the guinea pigs still sensitive to poison ivy were substantially hyposensitized (no longer responded to 1.5 or 0.80 microgram test doses of PDC). A control group of guinea pigs was not hyposensitized by injection of vehicle, and remained highly sensitive throughout the 15 week study. The majority of treated animals (less than 80%) were also hyposensitized to poison sumac and cashew nut shell liquid allergens.
Estimates of acute pesticide poisoning in agricultural workers in less developed countries.

The benefits of crop protection products have to be balanced against the risks to farmers and other agricultural workers handling and applying them. The extent of acute pesticide poisoning in these workers, particularly in less developed countries, has often been based on inadequate information. A number of approaches have been taken by researchers to acquire information on pesticide poisoning. These have resulted in worldwide (global) estimates and regional, localised or field assessments. The methods include descriptive epidemiology, cross-sectional and case studies. Attempts to estimate global pesticide poisonings have often been based upon extrapolations and assumptions from chemical-related fatalities in a small number of countries; such estimates do not provide reliable data. Epidemiological studies, relying mainly on hospital and poison centre data, have been biased towards the more severe poisonings, whereas field studies indicate that occupational pesticide poisoning is associated with less severe and minor effects. Many reports do not adequately distinguish between intentional, accidental and occupational pesticide poisoning statistics or are dominated by cases of intentional (suicidal) poisoning which, by their nature, result in severe or fatal results. The majority of reports do not adequately describe whether individual cases are minor, moderate or severe poisonings. In order to assess information on acute pesticide poisoning in agricultural workers in less developed countries and to draw conclusions on the extent and severity of occupational poisoning, the most recent (post-1990) literature was reviewed. Data were also derived from the World Health Organization (WHO), United Nations Environment Programme (UNEP) and the International Labour Office (ILO). The collected information was analysed to assess the extent and severity of occupational acute pesticide poisoning in less developed countries. Occupational acute pesticide poisonings in these

This study was conducted to describe the national magnitude and characteristics of acute pesticide poisoning among workers and customers in retail establishments. Analyses included retail employees 15-64 years of age and customers with acute pesticide poisoning identified from the Sentinel Event Notification System for Occupational Risks-Pesticides (SENSOR-Pesticides) and California Department of Pesticide Regulation from 1998 to 2004. Pesticide poisoning incidence rates and incidence rate ratios (IRR) were calculated. A total of 325 cases of acute pesticide poisoning were identified. Of these cases, 287 (88%) were retail employees and 38 (12%) were customers. Overall, retail employees had a significantly lower acute pesticide poisoning incidence rate compared with non-agricultural, non-retail employees (IRR=0.53; 95% confidence interval 0.47, 0.59). However, significantly elevated pesticide poisoning incidence rates were observed for four retail occupations (janitors, stock handlers/baggers, bakery/deli clerks, and shipping/receiving handlers). In addition, workers employed in two retail industry sectors (farm supply stores and hardware stores) had significantly elevated acute pesticide poisoning incidence rates. Incidence rates among the retail employees demonstrated a quadratic trend, monotonically decreasing from 1998 to 2000 and monotonically increasing from 2000 to 2003. The rates appear to have leveled off in 2003 and 2004. Preventive measures to decrease acute pesticide poisoning incidence in the retail sector include adoption of unbreakable and tear-resistant container requirements, increased utilization of integrated pest management strategies, and advisement to store managers, employees, and customers about poisoning prevention.

In Korea, registration of paraquat-containing herbicides was canceled in November 2011, and sales thereof were completely banned in November 2012. We evaluated the effect of the paraquat ban on the epidemiology and mortality of herbicide-induced poisoning. This retrospective study analyzed patients treated for herbicide poisoning at 17 emergency departments in South Korea between January 2010 and December 2014. The overall and paraquat mortality rates were compared pre- and post-ban. Factors associated with herbicide mortality were evaluated using logistic analysis. To determine if there were any changes in the mortality rates before and after the paraquat sales ban and the time point of any such significant changes in mortality, R software, version 3.0.3 (package, bcp) was used to perform a Bayesian change point analysis. We enrolled 2257 patients treated for herbicide poisoning (paraquat=46.8%). The overall and paraquat poisoning mortality rates were 40.6% and 73.0%, respectively. The decreased paraquat poisoning mortality rate (before, 75% vs. after, 67%, p=0.014) might be associated with increased intentionality. The multivariable logistic analysis revealed the paraquat ban as an independent predictor that decreased herbicide poisoning mortality (p=0.035). There were two major change points in herbicide mortality rates, approximately 3 months after the initial paraquat ban and 1 year after complete sales ban. This study suggests that the paraquat ban decreased intentional herbicide ingestion and contributed to lowering herbicide poisoning-associated mortality. The change point analysis suggests a certain timeframe was required for the manifestation of regulatory measures outcomes. © Copyright: Yonsei University College of Medicine 2017
Pesticide poisoning: a major health problem in Sri Lanka.

PubMed

Van der Hoek, W; Konradsen, F; Athukorala, K; Wanigadewa, T

1998-01-01

Acute pesticide poisoning is a major public health problem in Sri Lanka. In several agricultural districts, it precedes all other causes of death in government hospitals. Most of the acute poisoning cases are intentional (suicide) and occur among young adults, mainly males. Poisoning due to occupational exposure is also common, but less well documented. In an irrigation area in Sri Lanka a very high incidence of serious pesticide poisoning was observed, with 68% due to intentional ingestion of liquid pesticides. It is argued that the easy availability and widespread use of highly hazardous pesticides is the most important reason for this high number of poisoning cases. The frequent application of highly hazardous pesticides in high concentrations was often irrational and posed serious health and financial risks to the farmers. Sales promotion activities and credit facilities promoted this excessive pesticide use, which was not counteracted by an agricultural extension service. Hazardous practices when spraying pesticides were due to the impossibility of applying recommended protective measures under the local conditions, rather than to lack of knowledge. Current emphasis on programs that promote the safe use of pesticides through education and training of farmers will be ineffective in Sri Lanka because knowledge is already high and most poisoning cases are intentional. Instead, enforcement of legislation to restrict availability of the most hazardous pesticides would result in an immediate health benefit. Improved agricultural extension services to promote alternative non-chemical methods of pest control is the most important strategy, in the long term, to prevent acute pesticide poisoning.
Intravenous Poison Hemlock Injection Resulting in Prolonged Respiratory Failure and Encephalopathy.

Poison hemlock (Conium maculatum) is a common plant with a significant toxicity. Data on this toxicity is sparse as there have been few case reports and never a documented poisoning after intravenous injection. We present a case of intravenous poison hemlock injection encountered in the emergency department. We describe a 30-year-old male who presented to the emergency department after a brief cardiac arrest after injecting poison hemlock. The patient had return of spontaneous circulation in the emergency department but had prolonged muscular weakness and encephalopathy later requiring tracheostomy. Intravenous injection of poison hemlock alkaloids can result in significant toxicity, including cardiopulmonary arrest, prolonged weakness, and encephalopathy.

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.

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

Abstract Admission rate and length of stay (LOS) are two hospital performance indicators that affect the quality of care, patients’ satisfaction, bed turnover, and health cost expenditures. The aim of the study was to identify factors associated with higher admission rates and extended average LOS among acutely poisoned children at a single poison center, central Saudi Arabia. This is a cross-sectional, poison and medical chart review between 2009 and 2011. Exposures were child characteristics, that is, gender, age, body mass index (BMI), health history, and Canadian 5-level triage scale. Poison incident characteristics were, that is, type, exposure route, amount, form, home remedy, and arrival time to center. Admission status and LOS were obtained from records. Chronic poisoning, plant allergies, and venomous bites were excluded. Bivariate and regression analyses were applied. Significance at P < 0.05. Of the 315 eligible cases, (72%) were toddlers with equal gender distribution, (58%) had normal BMI, and (77%) were previously healthy. Poison substances were pharmaceutical drugs (63%) versus chemical products (37%). Main exposure route was oral (98%). Home remedy was observed in (21.9%), which were fluids, solutes, and/or gag-induced vomiting. Almost (52%) arrived to center >1 h. Triage levels: non-urgent cases (58%), less urgent (11%), urgent (18%), emergency (12%), resuscitative (1%). Admission rate was (20.6%) whereas av. LOS was 13 ± 22 h. After adjusting and controlling for confounders, older children (adj.OR = 1.19) and more critical triage levels (adj.OR = 1.35) were significantly associated with higher admission rates compared to younger children and less critical triage levels (adj.P = 0.006) and (adj.P = 0.042) respectively. Home remedy prior arrival was significantly associated with higher av. LOS (Beta = 9.48, t = 2.99), compared to those who directly visited the center, adj.P = 0.003. Hospital administrators
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.   PMID:9285467
Ciguatera poisoning in Vanuatu.

2003-02-01

Ciguatera poisoning is endemic in many tropical and subtropical countries. We conducted a retrospective study of admissions to two hospitals on the islands of Vanuatu in the southwestern Pacific region. We estimated the annual hospital admission rate for fish poisoning to be 65 (95% confidence interval [CI] = 55-75)/100,000 population on the island of Santo and 29 (95% CI = 19-43)/100,000 population on the island of Ambae. Hospital admission was more common in males 20-29 years old. Death was a rare complication. In the face of increases in both tourism and in the global trade in tropical and exotic fish, physicians in both endemic and non-endemic areas should be familiar with the epidemiology and clinical features of this important condition.

This case report presents two British medical students who contracted ciguatera poisoning while on elective in the Cook Islands. Thirty-six hours after consuming two reef fish they developed paraesthesia of the mouth, hands and feet, myalgia, pruritis and cold allodynia. Neurological examination was normal. Diagnosis of ciguatera poisoning was made on history of reef fish consumption and classical clinical presentation. Management was symptomatic (antihistamines) and both students made a full recovery within 10 weeks. PMID:24966268

Fish implicated in outbreaks of scombroid poisoning have usually undergone prolonged storage at an inadequate temperature. We report an outbreak of scombroid poisoning in which fish stored on ice for two days caused illness after standing at room temperature for only three to four hours; fish from the same catch did not cause illness after standing at room temperature only one hour. This outbreak suggests scombrotoxins may be produced more rapidly than previously thought possible. PMID:3631369

Scombroid poisoning is a form of toxicity caused by the ingestion of spoiled dark-flesh fishes, mainly of the scombroid family. The clinical picture is secondary to histamine toxicity, manifested as flushing, headache, palpitations, and abdominal cramps. The diagnosis is established on the basis of these typical clinical manifestations and fish-ingestion history. We report a case of a man with scombroid poisoning. He was diagnosed after presentation of two similar patients with the same epidemiological history.

During August-September 2004, four major hurricanes hit Florida, resulting in widespread power outages affecting several million households. Carbon monoxide (CO) poisonings during this period were investigated to identify ways to prevent future poisoning. Medical records from ten hospitals (two with hyperbaric oxygen chambers) were reviewed to identify individuals diagnosed with unintentional CO poisoning between August 13 and October 15, 2004. Multiple attempts were made to interview one person from each nonfatal incident. Medical examiner records and reports of investigations conducted by the U.S. Consumer Product Safety Commission of six fatal poisonings from five additional incidents were also reviewed. A total of 167 people treated for nonfatal CO poisoning were identified, representing 51 incidents. A portable, gasoline-powered generator was implicated in nearly all nonfatal incidents and in all fatal poisonings. Generators were most often located outdoors, followed by inside the garage, and inside the home. Telephone interviews with representatives of 35 (69%) incidents revealed that concerns about theft or exhaust most often influenced the choice of location. Twenty-six (74%) households did not own a generator before the hurricanes, and 86% did not have a CO detector at the time of the poisoning. Twenty-one (67%) households reported reading or hearing CO education messages before the incident. Although exposure to public education messages may have encouraged more appropriate use of generators, a substantial number of people were poisoned even when the devices were operated outdoors. Additional educational efforts and engineering solutions that reduce CO emission from generators should be the focus of public health activities.

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 <18 years with 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 < .001). Globally, there are substantial differences in the use and appropriateness of GID procedures in the management of pediatric poisonings. International best practices need to be better implemented.

Olanzapine is a second generation antipsychotic of thienobenzodiazepin group, which is used in the treatment of schizophrenia, bipolar disorder, and others, mainly psychiatric. Its multireceptor action (antagonism to dopaminergic D1, D2, D4, serotoninergic 5-HT2A, 5-HT2C, histaminergic H1, cholinergic M1-5, and a1--adrenergic receptors) results in multiple clinical symptoms in the course of acute poisoning. Evaluation of incidence and intensity of clinical symptoms in patients with of acute olanzapine intoxication. The pathophysiological mechanisms of particular symptoms are also described. 26 patients (mean age 37.7 +/- 15.3 years) hospitalized in 2005-2008 in toxicological centers in Krakow and Gdansk because of acute olanzapine poisoning (all patients had the toxic serum level of olanzapine above 100 ng/mL). The study group consisted of 11 men (29.3 +/- 8.5 years) and 13 women (44.9 +/- 16.4 years); 1 man and 1 woman were poisoned twice. Prospective analysis (using descriptive statistics) of data taken from medical anamnesis and results of physical examination, considering the following ones: consciousness disturbances (Glasgow Coma Scale, Matthew's scale, qualitative disturbances), vital signs (arterial blood pressure, heart rate, breathing rate, temperature), neurological findings (muscular tension, tendon reflexes, extrapyramidal symptoms, pupils) and others (oral and bronchial secretion, Poisoning Severity Score). The mean dose of ingested olanzapine in the study group was 352.5 +/- 220.0 mg, while the mean time since ingestion to hospital admission was 4.4 +/- 3.5 h. The half of the patients took other medicines together with olanzapine, and 23% consumed alcohol, as well. The following intensity of quantitative consciousness disturbances according to Matthew's scale were observed: grade 0 - 8%, I - 15%, II - 23%, III - 50%, and IV - 4%. The minimal and maximal values of blood pressure were: 102/63 +/- 16/14 and 163/ 97 +/- 27/18 mmHg, respectively; heart

Olanzapine is an atypical antipsychotic used for many years in the treatment of schizophrenia and bipolar disorder. Poisonings with this medicine can results with cardiotoxic effects in the form of ECG abnormalities. To evaluate the nature and incidence of electrocardiographic abnormalities in patients with acute olanzapine poisoning. 23 adult (mean age 38.4 +/- 15.5 years) patients with acute olanzapine poisoning, including 10 men (30.4 +/- 8.1 years) and 11 women (45.7 +/- 17.2 years), where 1 man and 1 woman were poisoned twice. The toxic serum level of olanzapine (above 100 ng/mL) was confirmed in each patient. Evaluation of electrocardiograms performed in patients in the first day of hospitalization with automatic measurement of durations of PQ, QRS and QTc and the identification of arrhythmias and conduction disorders on the basis of visual analysis of the ECG waveforms. Statistical analysis of the results using the methods of descriptive statistics. The mean durations of PQ, QRS and QTc in the study group were as follows: 135 +/- 23 ms, 91 +/- 12 ms, and 453 +/- 48 ms, respectively. The most common ECG abnormalities were prolonged QTc and supraventricular tachycardia (including sinus tachycardia) - each 22%; less common were ST-T changes (17%) and supraventricular premature complexes (9%), and only in individual cases (4%) ventricular premature complexes, bundle branch block, sinus bradycardia and atrial fibrillation were present. In the course of acute olanzapine poisonings: (1) prolonged QTc interval is quite common, but rarely leads to torsade de pointes tachycardia; (2) fast supraventricular rhythms are also common, but rarely cause irregular tachyarrhythmias, eg. atrial fibrillation; (3) conduction disorders (atrioventricular blocks, bundle branch blocks) are not typical abnormalities; (4) the observed ECG abnormalities emphasize the need of continuous ECG monitoring in these patients.
Characteristics of non-fatal self-poisoning in Sri Lanka: a systematic review

PubMed Central

2013-01-01

Background The rate of non-fatal self-poisoning in Sri Lanka has increased in recent years, with associated morbidity and economic cost to the country. This review examines the published literature for the characteristics and factors associated with non-fatal self-poisoning in Sri Lanka. Methods Electronic searches were conducted in Psychinfo, Proquest, Medline and Cochrane databases from inception to October 2011. Results 26 publications (representing 23 studies) were eligible to be included in the review. A majority of studies reported non-fatal self-poisoning to be more common among males, with a peak age range of 10–30 years. Pesticide ingestion was the most commonly used method of non-fatal self-poisoning. However three studies conducted within the last ten years, in urban areas of the country, reported non-fatal self-poisoning by medicinal overdose to be more common, and also reported non-fatal self-poisoning to be more common among females. Interpersonal conflict was the most commonly reported short-term stressor associated with self-poisoning. Alcohol misuse was reported among males who self-poisoned, and data regarding other psychiatric morbidity was limited. Conclusions The findings indicate that pesticide ingestion is the commonest method of non-fatal self-poisoning in Sri Lanka, and it is more common among young males, similar to other Asian countries. However there appears to be an emerging pattern of increasing medicinal overdoses, paralleled by a gender shift towards increased female non-fatal self-poisoning in urban areas. Many non-fatal self-poisoning attempts appear to occur in the context of acute interpersonal stress, with short premeditation, and associated with alcohol misuse in males. Similar to other Asian countries, strategies to reduce non-fatal self-poisoning in Sri Lanka require integrated intervention programs with several key aspects, including culturally appropriate interventions to develop interpersonal skills in young people

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

Acute poisoning is a significant health problem all over the world. In Malaysia, nationwide data on poisoning pattern is scarce and incomplete. The objectives of our study were to determine the pattern of acute drug and chemical poisoning at Penang General Hospital (PGH), in the northern region of Malaysia, and to compare poisoning characteristics between different ethnic groups. The study was a retrospective case review of all poisoned patients admitted to PGH during the years 2000-2002. We collected data concerning demographic parameters of patients, information about the agent(s) implicated, and circumstances surrounding the event. There were 493 poisoning incidents. Nearly two-thirds of the poisoned cases involved female patients. The predominant mode of poisoning was intentional (51.5%). The age group 15.1-30 years ranked at the top, constituting 55.2% of all cases. Drugs were the predominant agents implicated. Among cases associated with drugs, paracetamol was the main causative agent (44.7%). Chinese patients constituted 37.7% of all poisoning cases, followed by the Indians (31.6%) and Malays (26.6%). Between ethnic groups, Indian patients were found to have the highest rate of poisoning admission of 75.2 per 100,000 persons.
Food poisoning as an in-flight safety hazard.

The leading cause by far of airline pilot incapacitations is gastrointestinal illness resulting from "food poisoning". This potentially hazardous condition is inadequately dealt with by the airlines today and strikes equally in all pilot age groups. Sufficient incidents are occurring to justify more stringent aircrew meal standards and regulations. Aircrew heart attack and stroke concerns pale into insignificance relative to the far more common food poisoning incapacitations. Specific regulations on aircrew feeding should be promulgated by the Federal Aviation Administration and the regulatory authorities in other countries to preclude simultaneous-onset in-flight incapacitations due to common-source food poisoning.

The media can have a profound impact on human behavior. A sensational murder by ethylene glycol (EG) poisoning occurred in our state. The regional media provided extensive coverage of the murder. We undertook this investigation to evaluate our incidence of EG poisoning during the timeframe of before the first report linking a death to ethylene glycol to shortly after the first murder trial. Descriptive statistics and linear regression were used to describe and analyze the number of EG cases over time. A search of the leading regional newspaper's archives established the media coverage timeline. Between 2000 and 2004, our poison center (PC) handled a steady volume of unintentional exposures to EG [range: 105-123 per year, standard deviation (SD)=7.22]. EG exposures thought to be suicidal in intent increased from 12 cases in 2000 to 121 cases in 2004. In the 19 months prior to the first media report of this story, our PC handled a mean of 1 EG case with suicidal intent per month [range: 0-2, SD=.69]. In the month after the first media report, our PC handled 5 EG cases with suicidal intent. When media coverage was most intense (2004), our PC received a mean of 10 EG suicidal-intent calls per month [range: 5-17, SD=3.55]. Although uncommon, reports of malicious EG poisonings also increased during this same period from 2 in 2000 to 14 in 2004. Media coverage of stories involving poisonings may result in copycat events, applicable to both self-poisonings and concern for malicious poisonings. Poison centers should be aware of this phenomenon, pay attention to local media and plan accordingly if a poisoning event receives significant media coverage. The media should be more sensitive to the content of their coverage and avoid providing "how to" poisoning information.

Previous animal studies have reported that acute anticholinesterase pesticide (organophosphate and carbamate) poisoning may affect thyroid hormones. However, there is no human study investigating the association between hypothyroidism and anticholinesterase pesticide poisoning, and therefore, we conducted a retrospective nationwide population-based cohort study to delineate this issue. We identified 10,372 anticholinesterase pesticide poisoning subjects and matched 31,116 non-anticholinesterase pesticide poisoning subjects between 2003 and 2012 from the Nationwide Poisoning Database and the Longitudinal Health Insurance Database 2000, respectively, in a 1:3 ratio by index date, age, and sex for this study. We compared the cumulative incidence of hypothyroidism between the two cohorts by following up until 2013. Independent predictors for hypothyroidism were also investigated. In total, 75 (0.72%) anticholinesterase pesticide poisoning subjects and 184 (0.59%) non-anticholinesterase pesticide poisoning subjects were diagnosed with hypothyroidism during the follow-up. Cox proportional hazard regression analysis showed that anticholinesterase pesticide poisoning subjects had higher risk for hypothyroidism than did non-anticholinesterase pesticide poisoning subjects (adjusted hazard ratio: 1.47, 95% confidence interval: 1.11-1.95) after adjusting for age, sex, hypertension, malignancy, liver disease, renal disease, atrial fibrillation or flutter, thyroiditis, goiter, other endocrine disorders, and mental disorder. Stratified analysis showed that anticholinesterase pesticide poisoning subjects had higher risk for hypothyroidism than did non-anticholinesterase pesticide poisoning subjects in terms of the age subgroup of 40-64 years, female sex, past history of goiter, follow-up of <1 month, and anticholinesterase pesticide poisoning subjects without atropine treatment (incidence rate ratio [IRR]: 1.66, 95% confidence interval: 1.20-2.30).

Pesticide poisoning from agricultural labor has been recognized as a major public health problem among farmers worldwide. The objective of this study was to examine the incidence of acute occupational pesticide poisoning among male farmers in South Korea. A nationwide sampling survey of male farmers was conducted in South Korea. This survey used a stratified multistage probability sampling design and adopted the face-to-face interview method. A total of 1,958 male farmers were interviewed in order to estimate the incidence of acute occupational pesticide poisoning in rural areas in 2010. Based on a self-reported definition, the incidence rate in 2010 and the lifetime hospitalization rate due to acute occupational pesticide poisoning among male farmers were estimated. The incidence rate of acute occupational pesticide poisoning was 24.7 (95% CI 22.1-27.2) per 100 male farmers, which corresponds to 209,512 cases across South Korea in 2010. About 12% of the pesticide poisoning cases included either visiting a medical doctor or hospitalization. The lifetime rate of hospitalization due to occupational pesticide poisoning was 6.1 (95% CI 4.9-7.3) among male farmers. Poisoning occurred mainly when farmers were applying pesticides during summer. Our nationwide sampling survey demonstrated that acute occupational pesticide poisonings are highly prevalent among male South Korean farmers. Intensive intervention efforts to reduce occupational pesticide poisoning are urgently needed in South Korea. Copyright © 2012 Wiley Periodicals, Inc.

To explore the dose-effect relationship between vitamin C and paraquat (PQ) poisoning rats.  Methods: A total of 40 Sprague-Dawley (SD) rats were randomly divided into 4 groups: a control group, a PQ poisoning group, a vitamin C group 1 and a vitamin C group 2 (n=10 in each group). 150 mg/kg PQ was perfused into rat stomach to establish PQ poisoning rat model. In PQ poisoning group, 30 mg/kg methylprednisolone and 2.5 mg/kg cyclophosphamide were injected peritoneally on the basis of PQ poisoning rat model. In vitamin C1 and C2 group, vitamin C was injected at a dosage of 5 or 500 mg/kg, respectively. The control group only received normal saline (NS). The malondialdehyde (MDA), liver and kidney function as well as arterial blood gas in the blood were examined 36 h later. At the end, the rats were killed and took the liver tissues for pathological examination and weight ratio calculation. The glutathione peroxidase (GSH-PX), ctychrome C (Cyt C) in the liver tissues were detected by chromatometry, and the Bcl-2 was detected by Western blot.  Results: Compared with the PQ poisoning group, the MDA and Cyt C were decreased, the GSH-PX was increased, and liver and kidney functions were improved in the vitamin C group 1 (all P<0.01); but in the vitamin C group 2, the MDA increased and liver/kidney functions were impaired (all P<0.01). The expression of Bcl-2 in the PQ poisoning group was lower than that in the control group; compared with the PQ poisoning group, it was increased in the vitamin C1 group, while it was decreased in the vitamin C group 2 (both P<0.01). There was no obvious difference in the lung function, wet/dry weight ratio and pathological changes between the poisoning group and experimental groups (all P>0.05).  Conclusion: Vitamin C at the low dose shows a certain degree of protection for the liver and kidney in the PQ poisoning rats model through it antioxidative activity and anit-apoptosis activity, while vitamin C at the high does may promote

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.

Respiratory hazards significantly contribute to the burden of occupational disease among farmers. Pesticide exposure has been linked to an increased prevalence of respiratory symptoms in several farming populations. The purpose of this study was to evaluate the association between respiratory symptoms and pesticide poisoning in a cross-sectional survey of farm residents. A total of 761 farm operators and their spouses, representing 479 farms in northeastern Colorado, were recruited from 1993 to 1997. A personal interview asked whether the resident had experienced a pesticide poisoning and several respiratory conditions including cough, allergy, wheeze, and organic dust toxic syndrome (ODTS). Spirometry testing was performed on 196 individuals. Logistic regression was used to model the association of pesticide poisoning with respiratory conditions, and linear regression was used to model the relationship of pesticide poisoning and forced vital capacity (FVC) and forced expiratory volume (FEV1). In unadjusted models, pesticide poisoning was associated with all four respiratory conditions, and stayed significant in adjusted models of allergies and cough in non-smokers. In age- and gender-adjusted models, pesticide poisoning was significantly associated with lower FVC and FEV1 in current smokers and in those who were not heavy drinkers. Although this study should be reproduced in a larger sample, it suggests that further evaluation of the respiratory effects of pesticide exposure is warranted.

To describe the external causes of death and mortality trends due to injuries and poisoning in Mexican adolescents, from 1979 to 1997. This is a descriptive study of deaths occurring in Mexico from 1979 to 1997. Data were abstracted, coded, and entered in electronic format, by Instituto Nacional de Estadística, Geografía e Informática (National Institute of Statistics, Geography, and Informatics, INEGI). Data were analyzed during the second half of year 2000, in Jalisco, at the Research Unit of Epidemiologic and Adolescent Health Services, of Instituto Mexicano del Seguro Social (Mexican Institute of Social Security, IMSS). Injuries and poisoning ranked first as causes of adolescent mortality in Mexico (rate = 13.35/100,000), decreasing 41.4% from 1979 to 1997. However, an increasing trend was observed for homicides and suicides (9.5% y 104.0%, respectively). The most frequent mechanisms of injury were: motor vehicles, firearms, intoxications, suffocation, and drowning. Injuries and poisoning in developing countries show differences from those reported in developed countries. Further studies should be conducted to find preventive measures consistent with the sociocultural and environmental determinants of injuries and poisoning.

Poisoning does not occur either in 0.1 M KOH supernatant at CdO, but a partially reversible poisoning results from .0001 M CdCl2 and traces of fatty acid are present. Evidence indicates that the catastrophic poisoning affects the four-electron O2 reduction more than it does the one-electron H3O(+) discharge.

The recent discoveries of ricin, a deadly biologic toxin, at a South Carolina postal facility, a White House mail facility, and a US senator's office has raised concerns among public health officials, physicians, and citizens. Ricin is one of the most potent and lethal substances known, particularly when inhaled. The ease with which the native plant (Ricinus communis) can be obtained and the toxin extracted makes ricin an attractive weapon. To summarize the literature on ricin poisoning and provide recommendations based on our best professional judgment for clinicians and public health officials that are faced with deliberate release of ricin into the environment. LITERATURE ACQUISITION: Using PubMed, we searched MEDLINE and OLDMEDLINE databases (January 1950-August 2005). The Chemical and Biological Information Analysis Center database was searched for historical and military literature related to ricin toxicity. Book chapters, unpublished reports, monographs, relevant news reports, and Web material were also reviewed to find nonindexed articles. Most literature on ricin poisoning involves castor bean ingestion and experimental animal research. Aerosol release of ricin into the environment or adulteration of food and beverages are pathways to exposure likely to be exploited. Symptoms after ingestion (onset within 12 hours) are nonspecific and may include nausea, vomiting, diarrhea, and abdominal pain and may progress to hypotension, liver failure, renal dysfunction, and death due to multiorgan failure or cardiovascular collapse. Inhalation (onset of symptoms is likely within 8 hours) of ricin is expected to produce cough, dyspnea, arthralgias, and fever and may progress to respiratory distress and death, with few other organ system manifestations. Biological analytic methods for detecting ricin exposure are undergoing investigation and may soon be available through reference laboratories. Testing of environmental samples is available through federal reference

Plant poisoning occurs less commonly in dogs and cats than in herbivorous livestock, but numerous cases have been documented worldwide, most of them caused by common and internationally widely cultivated ornamental garden and house plants. Few cases of poisoning of cats and dogs have been reported in southern Africa, but many of the plants that have caused poisoning in these species elsewhere are widely available in the subregion and are briefly reviewed in terms of toxic principles, toxicity, species affected, clinical signs, and prognosis. The list includes Melia azedarach (syringa), Brunfelsia spp. (yesterday, today and tomorrow), Datura stramonium (jimsonweed, stinkblaar), a wide variety of lilies and lily-like plants, cycads, plants that contain soluble oxalates, plants containing cardiac glycosides and other cardiotoxins and euphorbias (Euphorbia pulcherrima, E. tirucalli). Poisoning by plant products such as macadamia nuts, onions and garlic, grapes and raisins, cannabis (marijuana, dagga) or hashish and castor oil seed or seedcake is also discussed. Many of the poisonings are not usually fatal, but others frequently result in death unless rapid action is taken by the owner and the veterinarian, underlining the importance of awareness of the poisonous potential of a number of familiar plants.

We report four cases of scombroid poisoning. During a lunch meeting three males had the same dish: a club sandwich with raw tuna. All developed erythema over the face and neck within two hours of eating the tuna. The severity of symptoms varied. Other symptoms were profuse sweating, a feeling of intense thirst and palpitations. The symptoms disappeared after few hours. Samples obtained from the tuna revealed histamine levels above the recommended FDA levels. We also report a case with similar symptoms after eating canned tuna in a mixed salad. Scombroid poisoning has been associated with the consumption of dark-flesh fish with high levels of histidine, which can be converted to histamine by decarboxylase from Gram-negative bacteria in the fish. The fish most often implicated is tuna. It is of great importance to increase the awareness of this type of poisoning for correct diagnosis and to prevent other cases by improving storage.

Cases of poisoning account for a distinct share of accidents in Germany, which is particularly high for accidents involving children. Cases of poisoning resulting from suicidal intent or abuse are not counted as accidents. Compared to other cases of disease and accidents, the numerical documentation of cases of poisoning is inadequate. Presently, there is no institution in Germany that could make available representative and meaningful data on the current state of poisoning. Owing to intensive scientific cooperation between the poison information centers (funded by the federal states) and the Poison and Product Documentation Center at the Federal Institute for Risk Assessment (BfR DocCenter) as well as to international cooperation, harmonized and standardized tools have been developed for the appropriate documentation and reporting of procedures to account for poisoning accidents. The first evaluation for 2005-2012 based on published and processed figures for the Federal Republic of Germany yielded the following results: Of approximately 230,000 telephone inquiries received in 2012, about 207,000 involved exposure of humans to different noxae. An annual increase of 3-5 % was recorded. For 2011, analyses of subsets processed by means of standardized methods yielded the following results: Medicines were involved in about 39 % of the cases recorded (of these, medicinal products for humans in 99 %); chemical/physicochemical agents in about 26 % (of these, cleaning and maintenance products in 46 %); products of daily use in about 14 % (of these, cosmetics in 40 %); and plants in about 10 %. More than 90 % of cases were acute poisoning and less than 5 %, chronic poisoning. Regarding the degree of severity of poisoning, an asymptomatic course was reported for 44 % of the cases; minor manifestations were experienced in 30 %, moderate ones in 6 %, and severe manifestations in 2 % of the cases recorded. Fatal cases were rare (< 0.1 %). The

Descriptive analysis of national mortality data, National Hospital Discharge Survey data, and American Association of Poison Control Centers national data for 1985 through 1990. There were 341 fatalities from agricultural and horticultural chemicals over the 6-year period, of which 64% were suicides, 28% were unintentional, and 8% were of undetermined intent. There were 25,418 hospitalizations; 78% were reported to be unintentional. Both deaths and hospitalizations occurred more frequently in males, and rates were higher in nonwhites than in whites. There were 338,170 poison exposures reported to poison centers for fungicides, herbicides, pesticides/insecticides, and rodenticides. Life-threatening manifestations or long-term sequelae occurred in 782 cases, and 97 deaths were reported. Pesticides and insecticides accounted for 72% of the poison center cases and 63% of the fatalities. Although they accounted for only 8% of poison exposures, herbicide deaths were disproportionately high (25%). Poisonings with agricultural and horticultural chemicals are an important public health problem. Prevention efforts need to incorporate the fact that many serious cases, such as paraquat poisonings, are suicidal in nature.

Amitraz is a pesticide used worldwide on animals and in agriculture. It contains triazapentadiene, which is a centrally acting alpha-2 adrenergic agonist. Amitraz poisoning is fairly uncommon in humans and occurs via oral, dermal or inhalational routes. Only a limited number of case reports of human intoxication have been published and most of them are of accidental ingestion by children. A twenty-year-old Sri Lankan female presented following self-ingestion of 20 ml of amitraz resulting in 37.8 mg/ kg of amitraz poisoning. She lost consciousness after 20 min of ingestion, developed bradycardia and hypotension, which needed intravenous fluid resuscitation and dobutamine. Gastric lavage was performed. Her bradycardia persisted for 36 h and she was drowsy for 48 h. She did not develop respiratory depression, convulsions or hypothermia and the urine output was normal. Arterial blood gas revealed mild respiratory alkalosis. She recovered fully within 48 h and was discharged on day 3. The clinical manifestations of amitraz (impaired consciousness, drowsiness, vomiting, disorientation, miosis, mydriasis, hypotension, bradycardia, respiratory depression, hypothermia, generalized seizures, hyperglycemia and glycosuria) can be explained by the agonist action of amitraz on α1 and α2 receptors. Management of amitraz poisoning is still considered to be supportive and symptomatic with monitoring of nervous system, cardiovascular and respiratory systems. Activated charcoal may still be considered for treatment and the place for gastric lavage is controversial. Atropine is effective for symptomatic bradycardia and inotropic support is needed for hypotension that does not respond to fluid resuscitation. Diazepam or Lorazepam is used for convulsions and some patients may require intubation and ICU care. Several α2 adrenergic antagonists like yohimbine have been tried on animals, which have successfully reversed the effects of amitraz. Since the majority of amitraz

Acute poisoning of chemical etiology is a significant global public health problem. The aim of this study was the analysis of the toxicoepidemiological structure of psychopharmacological drugs poisoning in Azerbaijan. We collected and analyzed the data on all cases of acute poisoning by psychopharmacological drugs (codes of categories T42/T43 ICD-10) undergoing inpatient treatment at the Center of Clinical Toxicology in Baku, Azerbaijan in 2009-2016. The total number of patients with acute intoxication by psychopharmacological drugs was 3,413, which was 48.3% of all cases of poisoning by drugs, medicaments and biological substances (T36-T50). The predominance of women was registered in all age groups. 1114 patients or 32.6% were in 15-24 years old age group. The highest percentage of poisonings at category T42 of ICD-10 were benzodiazepine-type drugs (35.8%), and at category T43 - antipsychotic and neuroleptic drugs (19.2%). In the structure of benzodiazepine poisoning, the first and second ranked places belonged to phenazepam (71.0%) and clonazepam - 16.6%. In addition, another 120 cases (5.5%) of poisonings in the T42 cohort were caused by "Z drugs", which have similar therapeutic effect to benzodiazepines (zolpidem and zopiclone). Among the antipsychotic and neuroleptic poisonings, thioridazine, trifluoperazine, levomepromazine, chlorpromazine, and periciazine accounted for 91% of all cases of intoxication in this cohort. Barbiturates, in view of their toxicity and narrow range of therapeutic dosages, now lost their importance as antiepileptic and hypnotic drugs. Only 4.9% of all cases of poisoning, classified under category T42, was due to the use of barbiturates (mainly phenobarbital). Poisonings with iminostilbenes were presented by carbamazepine poisoning only. Most patients in this cohort received this anticonvulsant drug as prescribed by a doctor. Acute intoxications by tricyclic antidepressants in 91.5% were presented by cases of amitriptyline poisoning

The aim of our study was to investigate the etiological and demographical characteristics of acute adult poisoning cases admitted to a university hospital in Tabriz, Iran. This retrospective study was performed on 1342 poisoning admissions to a university hospital from 2003 to 2005, by data collection from the medical records of patients. Poisonings were 5.40% of the total admissions. There was a predominance of female patients (55.7%) compared to male patients (44.3%) with a female-to-male ratio of 1.2:1. Most poisonings occurred in the age range of 11-20 years (38.9%). Drugs were the most common cause of poisonings (60.8%). Among the drug poisonings, benzodiazepines (40.31%) were the most frequent agents, followed by antidepressants (31.98%). The seasonal distribution in poisoning patients suggested a peak in spring (28%) and summer (27.5%). In 9.8% of cases accidental and in 90.2% intentional poisonings were evident. Most suicide attempts were made by women (58.51%) and unmarried people (51.4%).The mean duration of hospitalization was 3.02 +/- 2.8 days. There were 28 (2.3%) deaths; the majority (13 cases) was due to pesticides. This was a university hospital-based study, so these results may not be representative of the general population. Despite this drawback, these data still provide important information on the characteristics of the poisoning in this part of Iran. To prevent such poisonings, the community education about the danger of central nervous system-acting drugs and reducing the exposure period of people to pesticides are recommended.

Outpatient treatment of acute poisonings in Oslo: poisoning pattern, factors associated with hospitalization, and mortality

PubMed Central

2012-01-01

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

Case report about a 29-year old US-American patient who suddenly flew to Germany due to a schizoaffektive disorder. During a stay in our psychiatric hospital she refused food, liquid and medication because of fear of being poisoned. After four days her general condition had worsened rapidly so that parenteral nutrition was discussed. Surprisingly her poisoning delusion could be overcome by offering American "Junk-Food". From this moment on compliance in taking of medication improved too, so that renormalisation of her condition was achieved.

An epidemic of scopolamine poisonings occurred in Oslo in 2008 among users of illicit drugs, caused by fake Rohypnol pills. The clinical features, diagnostic process, and handling of the epidemic are presented. Suspected cases of scopolamine poisoning were extracted by reviewing registration forms from an ongoing prospective clinical study of acute poisonings in Oslo. Medical records of extracted contacts were examined and cases included according to specified clinical criteria. Forty-four cases of probable scopolamine poisoning were registered. Main clinical features were mydriasis, visual hallucinations, plucking behavior, agitation, and coma. No clinical diagnosis of anticholinergic syndrome was made prior to forensic analysis of the tablets, the most frequent diagnosis up to this point being unspecified drug-induced psychosis. Later in the epidemic, scopolamine poisoning became the dominating diagnosis. Ten patients were admitted to psychiatric hospitals, the rest recovered in medical units, or left health care against medical advice. Scopolamine poisonings are rare, but the resulting anticholinergic syndrome is well described. The syndrome was not recognized until the forensic analysis result strikingly changed how the patients were diagnosed and handled. A unique aspect of this epidemic was the intoxicating agent being scopolamine-containing tablets looking like Rohypnol, sold and used under the impression of being the latter. Recognizing the anticholinergic syndrome is important to provide proper treatment. Forensic analysis was the key to correct diagnosis in this outbreak, demonstrating its importance in verifying an epidemic of poisoning by fake drugs.

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.
Scombroid poisoning.

The symptoms of scombroid poisoning resemble an acute allergic reaction. Tuna, albacore, mackerel and bonito are implicated, as are nonscombroid fish such as mahi-mahi and bluefish. The histamine content of affected fish is high, but the pathophysiology is more complex than the mere ingestion of histamine. Antihistamines and cimetidine appear to be effective in controlling symptoms. Prevention consists of prompt and adequate refrigeration of dark-meated fish.

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. 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. 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%. 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.

Poisoning is a crucial public health problem which needs serious approach and response to treatment. In case of poisoning, proper first aid is lifesaving and application should be applied in every condition. This research was conducted in order to evaluate first aid knowledge of university students for poisoning. The research was conducted between the dates of May 2013-June 2013 with the permission gained from the University Rectorship. The cohort of the research contained 4,560 students who received education in Istanbul. The sample of the study included 936 students who accepted to participate in the research and attended the school during the research. The data were collected by using a questionnaire form, which had 21 questions prepared by researchers. Analysis of the data was carried out with a percentage evaluation method and chi square tests in a computer environment. In our study, 92.6% of students (n=867) knew the phone number of the ambulance in case of emergency. In addition, 57.3% of students (n=536) knew the phone number of the poison hotline, and it was seen that they answered correctly the questions regarding the relation between body system and indications of poisoning. It was determined that the students who received education in medical departments answered the questions correctly more than the students who had education in other departments. (p≤0.001, p≤0.01). It was observed that the university students in medical departments had more first aid knowledge on poisoning cases compared to the students in other departments who did not have sufficient information regarding these issues. It is thought that first aid education in all departments of universities, both poisoning and other first aid issues, should be conveyed to all students.

Poisonous plants have a devastating impact on the livestock industry as well as human health. To fully understand the effects of poisonous plants, multiple scientific disciplines are required. Chemical analysis of plant secondary compounds is key to identifying the responsible toxins, characterizing their metabolism, and understanding their effects on animals and humans. In this review, we highlight some of the successes in studying poisonous plants and mitigating their toxic effects. We also highlight some of the remaining challenges and opportunities with regards to the chemical analysis of poisonous plants.

Pesticide poisoning is a significant burden on health care systems in many low-income countries. This study evaluates cases of registered pesticide poisonings treated in selected rural (N = 101) and urban (N = 212) health facilities in Uganda from January 2010 to August 2016. In the urban setting, pesticides were the most prevalent single poison responsible for intoxications (N = 212 [28.8%]). Self-harm constituted a significantly higher proportion of the total number of poisonings in urban (63.3%) compared with rural areas (25.6%) where unintentional poisonings prevailed. Men were older than women and represented a majority of around 60% of the cases in both the urban and rural settings. Unintentional cases were almost the only ones seen below the age of 10, whereas self-harm dominated among adolescents and young persons from 10 to 29 years of age. Organophosphorus insecticides accounted for 73.0% of the poisonings. Urban hospitals provided a more intensive treatment and had registered fever complications than rural health care settings. To minimize self-harm with pesticides, a restriction of pesticide availability as shown to be effective in other low-income countries is recommended. Training of health care workers in proper diagnosis and treatment of poisonings and improved equipment in the health care settings should be strengthened.

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.

Previously, an average of less than one case per month was reported in the county. During the same period, OHD learned that eight intravenous-methamphetamine users (IVMUs) in Oregon thought to have NANB hepatitis had also been recently diagnosed with lead poisoning. A statewide media campaign describing the lead poisoning outbreak was conducted to alert IVMUs, physicians, and county health departments. In addition, OHD implemented a reportingmore » system for suspected and confirmed lead poisoning cases.

Pharmacological poisonings in young children are avoidable. Previous studies report calls to poisons centres, presentations to emergency departments (ED) or hospital admissions. There are limited data assessing concurrent management of poisonings across all three settings. We aimed to describe accidental pharmacological poisonings in young children across our Poisons Information Centre (PIC), EDs and hospitals. A population-based study in New South Wales, Australia, of PIC calls, ED presentations and hospital admissions for accidental pharmacological poisoning in children aged <5 years, 2007-2013. We examined trends, medicines responsible and subsequent management. Medicines were coded using ICD10-AM diagnosis codes (T36-50). Over 2007-2013, pharmacological poisonings accounted for 67,816 PIC calls, 7739 ED presentations and 2082 admissions. Rates (per 10,000 children) of PIC calls declined from 220 to 178; ED presentations were stable (∼22-24), with a decrease in emergency cases offset by an increase in semi- or non-urgent presentations; hospital admissions declined (8-5). Most PIC calls related to "non-opioid analgesics" (25%), and "topical agents" (18%). Nearly every day, one child aged <5 years was admitted to hospital for poisoning. "Benzodiazepines", "other and unspecified antidepressants", "uncategorised antihypertensives", and "4-aminophenol derivatives" accounted for over one-third of all admissions. Most PIC calls (90%) were advised to stay home, 6% referred to hospital. One-quarter of ED presentations resulted in admission. Poisonings reported to PIC and hospitals declined, however, non-urgent ED presentations increased. Strategies to reduce therapeutic errors and access to medicines, and education campaigns to improve Poisons Centre call rates to prevent unnecessary ED presentations are needed.

Statistical analyses based on incidence rate were carried out for organic solvent poisonings occurring in Japan. We used the published data of "Typical cases of occupational diseases" and "Current situation of occupational disease occurrence" in the "Industrial Hygiene Guidebook (Roudoueisei no Shiori)". The number of workers as a population of occupational solvent handlers was obtained from the Ministry of Health, Labour and Welfare, Japan. The annual incidences of solvent poisoning from 1995 to 2006, poisoning, death-by-poisoning, and secondary poisoning were 3.3-5.4, 0.0-0.83, and 0.0-0.34 cases/(100,000 solvent handlers × yr), respectively. Annual incidence classified by manufacturing, construction, and other services were 2.5, 52.0, and 6.1, respectively. Manufacturing showed a small increase from 1999 to 2003, and stopped increasing after 2004. Construction had a peak in 2000. Other services notably decreased from 14.4 in 1999 to 2.5 in 2006. The monthly distribution of the number of poisoning cases was prominent in January. Annual incidences of poisoning, death-by-poisoning, and secondary poisoning were 3.9, 0.5, 0.2 for toluene, 3.5, 0.5, 0.3 for xylene, and 16.4, 4.7, 2.3 for trichloroethylene, respectively. The annual incidences classified by industry and solvents showed no change for manufacturing, whereas that for construction notably decreased from 88.6 in 2000 to 12.0 in 2006.

An outbreak of scombroid poisoning occurred in San Francisco in the fall of 1977. The vehicle was sashimi prepared from spoiled tuna fish. Prompt public health measures prevented further consumption of the implicated food. Laboratory studies showed the presence in the tuna of bacterial species capable of producing large amounts of histamine, a substance strongly implicated in scombroid poisoning. Chemical analysis showed that histamine is very unevenly distributed in the flesh of spoiling tuna, therefore accounting for the sometimes random occurrence of disease among people eating the same food at the same table.

The role of pesticide poisoning in risk of injuries may operate through a link between pesticide-induced depressive symptoms and reduced engagement in safety behaviors. The authors conducted structural equation modeling of cross-sectional data to examine the pattern of associations between pesticide poisoning, depressive symptoms, safety knowledge, safety behaviors, and injury. Interviews of 1637 Colorado farm operators and their spouses from 964 farms were conducted during 1993-1997. Pesticide poisoning was assessed based on a history of ever having been poisoned. The Center for Epidemiologic Studies-Depression scale was used to assess depressive symptoms. Safety knowledge and safety behaviors were assessed using ten items for each latent variable. Outcomes were safety behaviors and injuries. A total of 154 injuries occurred among 1604 individuals with complete data. Pesticide poisoning, financial problems, health, and age predicted negative affect/somatic depressive symptoms with similar effect sizes; sex did not. Depression was more strongly associated with safety behavior than was safety knowledge. Two safety behaviors were significantly associated with an increased risk of injury. This study emphasizes the importance of financial problems and health on depression, and provides further evidence for the link between neurological effects of past pesticide poisoning on risk-taking behaviors and injury.

Ciguatera fish poisoning (CFP) is the most prevalent non-bacterial food-borne form of poisoning in French Polynesia, which results from the consumption of coral reef fish naturally contaminated with ciguatoxins produced by dinoflagellates in the genus Gambierdiscus . Since the early 2000s, this French territory has also witnessed the emergence of atypical forms of ciguatera, known as ciguatera shellfish poisoning (CSP), associated with the consumption of marine invertebrates. In June 2014, nine tourists simultaneously developed a major and persistent poisoning syndrome following the consumption of the gastropod Tectus niloticus collected in Anaho, a secluded bay of Nuku Hiva Island (Marquesas Archipelago, French Polynesia). The unusual nature and severity of this event prompted a multidisciplinary investigation in order to characterize the etiology and document the short/long-term health consequences of this mass-poisoning event. This paper presents the results of clinical investigations based on hospital medical records, medical follow-up conducted six and 20 months post-poisoning, including a case description. This study is the first to describe the medical signature of T. niloticus poisoning in French Polynesia and contributed to alerting local authorities about the potential health hazards associated with the consumption of this gastropod, which is highly prized by local communities in Pacific island countries and territories.

Managing aluminum phosphide poisonings

2011-01-01

Aluminum phosphide (AlP) is a cheap, effective and commonly used pesticide. However, unfortunately, it is now one of the most common causes of poisoning among agricultural pesticides. It liberates lethal phosphine gas when it comes in contact either with atmospheric moisture or with hydrochloric acid in the stomach. The mechanism of toxicity includes cellular hypoxia due to the effect on mitochondria, inhibition of cytochrome C oxidase and formation of highly reactive hydroxyl radicals. The signs and symptoms are nonspecific and instantaneous. The toxicity of AlP particularly affects the cardiac and vascular tissues, which manifest as profound and refractory hypotension, congestive heart failure and electrocardiographic abnormalities. The diagnosis of AlP usually depends on clinical suspicion or history, but can be made easily by the simple silver nitrate test on gastric content or on breath. Due to no known specific antidote, management remains primarily supportive care. Early arrival, resuscitation, diagnosis, decrease the exposure of poison (by gastric lavage with KMnO4, coconut oil), intensive monitoring and supportive therapy may result in good outcome. Prompt and adequate cardiovascular support is important and core in the management to attain adequate tissue perfusion, oxygenation and physiologic metabolic milieu compatible with life until the tissue poison levels are reduced and spontaneous circulation is restored. In most of the studies, poor prognostic factors were presence of acidosis and shock. The overall outcome improved in the last decade due to better and advanced intensive care management.

2012-01-01

Background Acute poisoning is a major public health issue in many parts of the world. The epidemiology and the mortality rate is higher in low and middle income countries, including Sri Lanka. The aim of this study was to provide details about the epidemiology of acute poisoning in a rural Sri Lankan district and to identify the changing patterns and epidemiology of poisoning. Methods A prospective study was conducted from September 2008 to January 2010 in all hospitals with inpatient facilities in Anuradhapura district of North Central Province of Sri Lanka. Acute poisoning data was extracted from patient charts. Selected data were compared to the data collected from a 2005 study in 28 hospitals. Results There were 3813 poisoned patients admitted to the hospitals in the Anuradhapura district over 17 months. The annual population incidence was 447 poisoning cases per 100,000 population. The total number of male and female patients was approximately similar, but the age distribution differed by gender. There was a very high incidence of poisoning in females aged 15–19, with an estimated cumulative incidence of 6% over these five years. Although, pesticides are still the most common type of poison, medicinal drug poisonings are now 21% of the total and have increased 1.6 fold since 2005. Conclusions Acute poisoning remains a major public health problem in rural Sri Lanka and pesticide poisoning remains the most important poison. However, cases of medicinal drug poisoning have recently dramatically increased. Youth in these rural communities remain very vulnerable to acute poisoning and the problem is so common that school-based primary prevention programs may be worthwhile.

As copper sulphate pentahydrate (CSP) is a common compound used in agriculture and industry, chronic occupational exposures to CSP are well known, but acute poisoning is rare in the Western world. This case report describes acute poisoning of a 33-year-old woman who attempted suicide by ingesting an unknown amount of CSP. On admission to the hospital, she had symptoms and signs of severe hemorrhagic gastroenteritis, dehydration, renal dysfunction and methaemoglobinaemia with normal serum copper level. Therapy included early gastric lavage, fluid replacement, vasoactive drugs, furosemide, antiemetic drugs, ranitidine, and antidotes methylene blue and 2,3-dimercaptopropane-1-sulphonate (DMPS). However, the patient developed severe intravascular haemolysis, acute severe hepatic and renal failure, as well as adrenal insufficiency. After prolonged, but successful hospital treatment, including haemodialysis and IV hydrocortisone, the patient was discharged with signs of mild renal and liver impairment. Our conclusion is that in severe cases of copper poisoning early supportive measures are essential. In addition, antidotes such as methylene blue for methaemoglobinaemia and chelating agent such as DMPS improve morbidity and survival of severely poisoned victims.

To investigate the epidemiological characteristics of acute pesticide poisoning in Jinan, China and to provide effective proposals for the prevention and control of pesticide poisoning. Reported cases of acute pesticide poisoning from 2007 to 2013 in Jinan were collected and subjected to statistical analysis using SPSS 17. A total of 4852 cases of acute pesticide poisoning were reported from 2007 to 2013 in Jinan. The fatality rate was 14.10%. The incidence of non-occupational poisoning accounted for 94.23% (4 572/4 852). The incidence of occupational poisoning showed a decreasing trend from 2007 to 2013, with most cases poisoned by insecticides (236 cases, accounting for 82.86% of all cases of occupational poisoning). Among non-occupational poisoning cases, fatality rate was higher in cases aged 60 years or over than in those under 60 years; fatality rate was higher among male cases (16.11%) than among female cases (13.79%); herbicides had a significantly higher lethal rate (22.25%) than insecticides (14.02%) (P < 0.05). More attention should be paid to acute pesticide poisoning in Jinan, and effective management measures should be taken immediately.

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, increasing until

Background 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. Methods and Findings We calculated directly age-standardised mortality rates for paracetamol poisoning in England and Wales from 1993 to 2004.

To investigate the effects of controlling the specific dangerous pesticides on prevention of acute pesticide poisoning in rural area. The data of reported cases of pesticide poisoning were analyzed to find out the specific dangerous pesticide in acute pesticide poisoning. Then the occurrence of occupational pesticide poisoning and fatality of non-occupational pesticide poisoning were estimated under the hypothesis of removing the specific dangerous pesticides. The data indicated that parathion (including methyl parathion) was the specific dangerous pesticide inducing occupational pesticide poisoning. After removing the use of parathion, the hazard of pesticides which caused occupational pesticide poisoning would be significantly decreased (P < 0.01). Parathion was also the most dangerous pesticide which caused non-occupational pesticide poisoning, with its fatality up to 15.8%. If parathion was well controlled, the fatality of non-occupational pesticide poisoning would be declined from 9.4% to 7.4%. The analyses of related literatures also revealed the similar results. The occurrence of occupational pesticide poisoning and fatality of non-occupational pesticide poisoning may decrease if the most dangerous pesticides are well supervised.
A review of lead poisoning in swans

USGS Publications Warehouse

Blus, L.J.

1994-01-01

Nearly 10,000 swans of six species or subspecies from 14 countries have died from poisoning caused by lead that originated from ingestion of fishing weights, shotgun pellets (shot), or contaminated vegetation or sediments associated with mining and smelting wastes. Lead contamination in mute swans in England caused local population declines during the late 1970s and 1980s. More tundra swans died from lead poisoning than any other species. The extreme record involved an estimated 7200 tundra swans that died over five winters at one locality in North Carolina. The recent legislation to ban lead fishing weights in most of England and Wales and recent replacement of lead shot with steel shot for waterfowl hunting in the United States and a few areas of Europe, including Denmark, are expected to reduce the incidence of lead poisoning in swans.
Deaths from pesticide poisoning in England and Wales: 1945-1989.

1. Data on deaths from pesticide poisoning occurring in England and Wales between 1945 and 1989 (no data are available for 1954) have been collated; pesticides were responsible for only 1012 (1.1%) of the 87,385 deaths from poisoning (excluding those due to carbon monoxide) occurring over this 44 year period. At least 73% of all pesticide fatalities were due to suicide and overall there was a predominance of males (male:female ratio 2.4:1). No deaths from pesticide poisoning in children under 10 years have been reported since 1974 although almost 50% of suspected pesticide poisoning incidents involve this age group. 2. Herbicides were responsible for 787 (78%) fatal poisonings, 110 (11%) were caused by insecticides, 69 (6.8%) by rodenticides, 30 (3.0%) by wood preservatives and 16 (1.6%) by other pesticides. 3. The herbicide, paraquat, was responsible for 570 of 1012 (56%) deaths and, although there has been a progressive decline in the annual number of deaths from paraquat poisoning since 1982, paraquat remains the most common cause of fatal pesticide poisoning in England and Wales. 4. Sodium chlorate caused 113 (11.2%) deaths, most of these fatalities occurring between 1965 and 1983; only one death has been recorded since 1984. The phenoxyacetate herbicides resulted in 50 deaths; 2,4-D was implicated most commonly. Sixty-eight deaths were due to organophosphorus insecticides; demeton-S-methyl, malathion and mevinphos were involved most frequently. Only eight deaths resulted from organochlorine insecticides and two of these also involved an organophosphorus insecticide.(ABSTRACT TRUNCATED AT 250 WORDS)

To describe the epidemiological characteristics of acute pesticide poisoning in Shaoxing, China during 2006-2011 and to provide a reference for the prevention and control of pesticide poisoning. The data on pesticide poisoning in Shaoxing during 2006-2011 were obtained from the China Information System for Disease Control and Prevention and were then analyzed. A total of 2024 cases of acute pesticide poisoning were reported in Shaoxing during 2006-2011, and 44 cases were missed, accounting for 2.1% (44/2068) of all cases. Among the 2024 cases, 119 (5.9%) died; the fatality rates of productive poisoning and unproductive poisoning were 1.0% (3/289) and 6.7% (116/1735), respectively. The reported cases included 1038 (51.3%) females and 986 (48.7%) males, and there were no significant differences in the ratio between male and female cases of acute pesticide poisoning from 2006 to 2011 (χ2 = 9.16, P = 0.10). The 2024 cases had a mean age of 47.0±18.7 years; the male cases had a significantly higher mean age than the female cases (50.7±19.0 vs 43.4±17.8 years, t = 9.01, P < 0.001). Among the 2024 cases, 289 (14.3%) suffered productive poisoning, and 1735 (85.7%) suffered unproductive poisoning. In the 986 male cases, 219 (22.2%) suffered productive poisoning; in the 1038 female cases, 968 (93.3%) suffered unproductive poisoning. The pesticides that caused poisoning included insecticide (86.7%, 1754/2024), herbicide (5.1%, 104/2024), rodenticide (3.6%, 72/2024), and bactericide, mixed preparation, biochemical pesticides, and other four categories of pesticides (4.6%, 94/2024); of the 1754 cases caused by insecticide, 1455 (83.0%) were attributed to organophosphorus insecticide. The incidence of unproductive acute pesticide poisoning is high in Shaoxing, and it mainly affects females. Most cases of acute pesticide poisoning are aged 30∼60 years. Insecticide is the main cause of poisoning. It is necessary to enhance health knowledge popularization and safety
Hot charcoal vomitus in aluminum phosphide poisoning - A case report of internal thermal reaction in aluminum phosphide poisoning and review of literature

Aluminium phosphide (ALP) poisoning is a commonly encountered poisoning in emergency departments in most developing countries. Many papers have revealed metabolic derangements in this poisoning and also examined contributing factors leading to death, but only few have reported physical damage. Some case reports have described a complication that has been frequently termed ‘ignition’. The exact mechanism of this phenomenon has not been fully elucidated. An exothermic reaction during therapeutic administration of chemicals may contribute to this problem, but the incidence has occurred in the absence of treatment or drug administration. Here, we report a 34-year-old woman with ALP poisoning who presented with hot charcoal vomitus, a sign of internal thermal event, leading to the thermal burning of the patient's face and internal damage resulting in death. We reviewed all reported cases with similar complication to demonstrate varied characteristics of patients and to propose the possible mechanisms leading to this event. PMID:26257417

The distinctive yellow Lance Armstrong 'Live Strong' silicon wristbands, which support cancer research, have reached iconic status and spawned substantial interest from other organizations seeking to capitalize on the same awareness opportunity. To promote the national toll-free Poison Help telephone number, a regional poison information center developed and introduced a Poison Help wristband. The RPIC worked with a marketing firm to design the Poison Help wristband, conduct a feasibility analysis to determine the financial viability of the project and develop a plan to market and sell the wristbands. The wristbands were a unique color, contained the words Poison Help and the national toll-free telephone number. Approximately 50,000 wristbands were distributed in the first four months. By developing a practical application for a popular item, the RPIC increased poison center awareness and, as a secondary benefit, generated revenue to support other poison prevention education endeavors.

The histamine content and the total vagal stimulating activities in various fish samples involved in an outbreak of food poisoning were compared. There was a close correlation between the two levels and there was lack of potentiation between histamine and other non-active fractions. The role of histamine in scombroid poisoning is discussed in the light of these results.

BACKGROUND Ethylene glycol poisoning remains an important presentation to Emergency Departments. Quick diagnosis and treatment are essential to prevent renal failure and life-threating complications. CASE REPORT In this case report, we present a patient who was admitted unconscious to the hospital. Ethylene glycol poisoning was immediately suspected, because the patient had previously been hospitalized with similar symptoms after intake of antifreeze coolant. A urine sample was sent for microscopy and showed multiple calcium oxalate monohydrate (COM) crystals, which supported the clinical suspicion of ethylene glycol poisoning. The patient was treated with continuous intravenous ethyl alcohol infusion and hemodialysis. Two days after admission, the patient was awake and in clinical recovery. CONCLUSIONS Demonstration of COM crystals using microscopy of a urine sample adds valuable information supporting the clinical suspicion of ethylene glycol poisoning, and may serve as an easy, quick, and cheap method that can be performed in any emergency setting.

Epidemiologic data related to agricultural pesticide poisoning cases in Burkina Faso were collected. The study was carried out using retrospective (from January 2002 to June 2010) surveys conducted among farmers and healthcare centers. One hundred and fifty-three (153) pest control products were recorded during the survey and 56 active ingredients were identified. Out of the 153 pest control products, 49 (i.e. 32%) were authorized for sale in Burkina Faso. The main risk factors are socio-demographic characteristics of farmers, their low education level, and some attitudes and practices on using agricultural pesticides. Pesticide poisonings are relatively frequent and their management was not always efficacious. Actions are needed to reduce pesticide poisoning as a global public health problem and to improve management of pesticide poisoning. To this purpose, advanced investigations should be carried out over a longer period of time to complement the present pilot study. PMID:24678256

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
