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

    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

    High weight percent Gd/sub 2/O/sub 3/ has given excellent results when applied as burnable poison in pressurized water reactors for advanced fuel management tasks. Poisoning of up to 9 weight% Gd/sub 2/O/sub 3/ has been implemented in commercial reload cores to match the requirements of full low leakage loading and cycle extension strategies. Operational performance has confirmed that the high degree of accuracy achieved for calculational methods for standard loading applications also applies for highly Gd poisoned cores. The UO/sub 2/-Gd/sub 2/O/sub 3/ fabrication process has been rationalized by the use of direct pelletizing.

    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). Hence 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.

  5. Development of Improved Burnable Poisons for Commercial Nuclear Power Reactors

    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. 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 pressurized

    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), Xuthos (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.

    Highlights: Black-Right-Pointing-Pointer A fuel rod optimization for the coupled bundle-core design in a BWR is developed. Black-Right-Pointing-Pointer An algorithm to minimize the rod power peaking factor is used. Black-Right-Pointing-Pointer The fissile content is divided in two factors. Black-Right-Pointing-Pointer A reactor physics analysis of these factors is performed. Black-Right-Pointing-Pointer The algorithm is applied to a typical BWR fuel lattice. - Abstract: The main goals in nuclear fuel lattice design are: (1) minimizing the rod power peaking factor (PPF) in order that the power level distribution is the most uniform; (2) obtaining a prescribed target value for the multiplication factor (k) at the end of the irradiation in order that the fuel lattice reaches the desired reactivity; and (3) obtaining a prescribed target value for the k at the beginning of the irradiation in order that the reactivity excess is neither a high value (to ease the maneuvering of the control systems) nor a low value (to avoid the penalization of the high cost of the burnable poison content). In this work a simple algorithm to design the burnable poison bearing nuclear fuel lattice is presented. This algorithm is based on a reactor physics analysis. The algorithm is focused on finding the radial distribution of the fuel rods having different fissile and burnable poison contents in order to obtain: (1) an adequate minimum PPF; (2) a prescribed target value of the k at the end of the irradiation; and (3) a prescribed target value of the k at the beginning of the irradiation. This algorithm is based on the factorization of the fissile and burnable poison contents of each fuel rod and on the application of the first-order perturbation theory. The performance of the algorithm is demonstrated with the design of a fuel lattice composed of uranium dioxide (UO{sub 2}) and gadolinium dioxide (Gd{sub 2}O{sub 3}) for boiling water reactors (BWR). This algorithm has been accomplished

    The University of Florida (UF) is carrying out basic research on a new class of thermally stable boron containing materials that from early indications appear to have special properties that will greatly enhance the performance of Burnable Poison Rod Assemblies (BPRA(tm)s) and address one of the major disadvantages of the use of boron shims. The new class of polymer materials, poly-acetylenic carbonyl-siloxane, termed ''Carborane'', were developed by Dr. T. Keller of the Naval Research Laboratory (NRL). Dr. T. Keller is cooperating in this research effort. Other classes of boron containing polymer materials are also under review. Displacement of water by the boron shims incurs an ''end of cycle reactivity penalty'' since at the end of cycle the moderator coefficient is strongly negative. ''Carborane'' has the property of being able to contain a tailored amount of boron while maintaining an extremely high hydrogen content, and at the same time being extremely stable to high temperatures and to neutron irradiation. Tests run by the NRL have shown that ''Carborane'' is stable to about 1000 C. The high hydrogen and carbon content contained in the ''Carborane'' Polymer offsets the large fuel cycle reactivity penalty which occurs with current generation BPRA(tm)s, as a result of the reactivity loss resulting from the BPRA(tm)s displacement of moderator water in the guide tubes of Pressurized Water Reactor (PWR) assemblies. Current generation BPRA utilize B{sub 4}C in an Al{sub 2}O{sub 3} matrix. In an attempt to minimize the reactivity penalty from water displacement, Westinghouse has developed a costly annular BPRA, called the Wet Annular Burnable Absorber (WABA) assembly. This burnable poison rod design reduces the moderator displacement by 22% by the use of a central annular water hole. The ''Carborane'' matrix proposed by the University of Florida

    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 a 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 of

    Highlights: • New advanced burnable poison rods (BPR) are suggested for low boron operation in PWR. • The new SMR cores have long cycle length of ∼4.5 EFPYs with low boron concentration. • The SMR core satisfies all the design targets and constraints. - Abstract: In this paper, new small long-cycle PWR (Pressurized Water Reactor) cores for low boron concentration operation are designed by employing advanced burnable poison rods (BPRs) in which the BISO (Bi-Isotropic) particles of burnable poison are distributed in a SiC matrix. The BPRs are designed by adjusting the kernel diameter, the kernel material and the packing fraction to effectively reduce the excess reactivity in order to reduce the boron concentration in the coolant and achieve a flat change in excess reactivity over a long operational cycle. In addition, axial zoning of the BPRs was suggested to improve the core performances, and it was shown that the suggested axial zoning of BPRs considerably extends the cycle length compared to a core with no BPR axial zoning. The results of the core physics analyses showed that the cores using BPRs with a B{sub 4}C kernel have long cycle lengths of ∼4.5 EFPYs (Effective Full Power Years), small maximum CBCs (Critical Boron Concentration) lower than 370 ppm, low power peaking factors, and large shutdown margins of control element assemblies.

  11. 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 staff 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 BPRs

    A tendency to increase the discharge burnup of nuclear fuel for Advanced Pressurized Water Reactors (PWR) has been a characteristic of its operation for many years. It will be able to burn at very high burnup of about 70 GWd/t with UO{sub 2} fuels. The U-235 enrichment must be higher than 5 %, which leads to the necessity of using an extremely efficient burnable poison like Gadolinium oxide. Using gadolinium isotope is significant due to its particular depletion behavior (''Onion-Skin'' effect). In this paper, the MCNPX2.7 code is used to calculate the important neutronic parameters of the next generation fuels of PWR. K-infinity, local peaking factor and fission rate distributions are calculated for a PWR assembly which burn at very high burnup reaching 70 GWd/t. The calculations are performed using the recently released evaluated Gadolinium cross section data. The results obtained are close to those of a LWR next generation fuel benchmark problem. This demonstrates that the calculation scheme used is able to accurately model a PWR assembly that operates at high burnup values.

    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 and 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.

    In block-type high temperature gas-cooled reactors (HTGRs), insertion depth of control rods (CRs) into a core should be retained shallow to keep fuel temperature below 1495 {sup o}C through a burnup period, and hence excess reactivity should be reduced through a different method. Loading burnable poisons (BPs) into the core is considered as a method to resolve this problem as in case of light water reactors (LWRs). Effectiveness of BPs on reactivity control in LWRs has been validated by experimental data, however, this has not been done yet for HTGRs, because there was not enough burnup characteristics data for HTGRs required for the validation. The High Temperature Engineering Test Reactor (HTTR) is a block-type HTGRs and it adopts rod-type BPs to control reactivity. The HTTR has been operated up to middle burnup, and thereby the experimental data was expected to show effect of the BPs on the reactivity control. Hence, in order to validate effectiveness of rod-type BPs on reactivity control in the HTTR, we investigated on the HTTR results whether the BPs have functioned as designed. As a result, the CRs insertion depth has been retained shallow within allowable range, and then effectiveness of rod-type BPs on reactivity control in the HTTR was validated.

    In this research, for the first time, a new optimization method, i.e., strength Pareto evolutionary algorithm II (SPEA-II), is developed for the burnable poison placement (BPP) optimization of a nuclear reactor core. In the BPP problem, an optimized placement map of fuel assemblies with burnable poison is searched for a given core loading pattern according to defined objectives. In this work, SPEA-II coupled with a nodal expansion code is used for solving the BPP problem of Kraftwerk Union AG (KWU) pressurized water reactor. Our optimization goal for the BPP is to achieve a greater multiplication factor (K-e-f-f) for gaining possible longer operation cycles along with more flattening of fuel assembly relative power distribution, considering a safety constraint on the radial power peaking factor. For appraising the proposed methodology, the basic approach, i.e., SPEA, is also developed in order to compare obtained results. In general, results reveal the acceptance performance and high strength of SPEA, particularly its new version, i.e., SPEA-II, in achieving a semioptimized loading pattern for the BPP optimization of KWU pressurized water reactor.

    Safeguards inspection measurements must be performed in a timely manner in order to detect the diversion of significant quantities of nuclear material. A shorter measurement time can increase the number of items that a nuclear safeguards inspector can reliably measure during a period of access to a nuclear facility. In turn, this improves the reliability of the acquired statistical sample, which is used to inform decisions regarding compliance. Safeguards inspection measurements should also maintain independence from facility operator declarations. Existing neutron collars employ thermal neutron interrogation for safeguards inspection measurements of fresh fuel assemblies. A new fast neutron collar has been developed for safeguards inspection measurements of fresh low-enriched uranium (LEU) fuel assemblies containing gadolinia (Gd2O3) burnable poison rods. The Euratom Fast Collar (EFC) was designed with high neutron detection efficiency to make a fast (Cd) mode measurement viable whilst meeting the high counting precision and short assay time requirements of the Euratom safeguards inspectorate. A fast mode measurement reduces the instrument sensitivity to burnable poison rod content and therefore reduces the applied poison correction, consequently reducing the dependence on the operator declaration of the poison content within an assembly. The EFC non-destructive assay (NDA) of typical modern European pressurized water reactor (PWR) fresh fuel assembly designs have been simulated using Monte Carlo N-particle extended transport code (MCNPX) simulations. Simulations predict that the EFC can achieve 2% relative statistical uncertainty on the doubles neutron counting rate for a fast mode measurement in an assay time of 600 s (10 min) with the available 241AmLi (α,n) interrogation source strength of 5.7×104 s-1. Furthermore, the calibration range of the new collar has been extended to verify 235U content in variable PWR fuel designs in the presence of up to 32

    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 nitial 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.

    Burnable poison rods, made of B{sub 4}C- Al{sub 2} O{sub 3} pellets with 5.01 mg/cm{sup 3} {sup 10} B concentration, have been manufactured for a set of experiments in the IPEN/MB-01 zero-power reactor. Several core parameters which are affected by the burnable poisons rods have been measured. The principal results, for the situation in which the burnable poison rods are located near the absorber rods of a control rod, are they cause a 29% rod worth shadowing, a reduction of 39% in the local void coefficient of reactivity, a reduction of 4.8% in the isothermal temperature coefficient of reactivity, and a reduction of 9% in the thermal neutron flux in the region where the burnable poison rods are located. These experimental results will be used for the validation of burnable poison calculation methods in the CTMSP. (author)

    Thorium has higher neutron absorption cross section than that of U-238. Thus, the thorium mixed uranium oxide nuclear fuel can reduce the initial excessive reactivity and the long-live radio-wastes with increasing the fuel utilization efficiency. In this study, a preliminary study on the application of the thorium/uranium mixed fuel is performed for the alternative of the PLUS7 fuel assembly which includes burnable poison. A conceptual design without geometrical change is proposed and the reactor characteristics are analyzed. In this study, a fuel assembly using the uranium/thorium mixed fuel was designed to substitute the assembly which includes burnable poison. The reactor characteristics, which are k{sub inf}, power distribution and plutonium production rate, were evaluated and the results are compared with the E1 assembly which is used in the OPR1000 reactor. The results show that the proposed design can efficiently reduce the excessive reactivity, peak power, and plutonium production with increasing the fuel utilization period.

    All of cobalt-60 sources are imported to Korea. CANDU units are generally used to produce cobalt-60 at Bruce and Point Lepreau in Canada and Embalse in Argentina. China has started production of cobalt-60 using its CANDU 6 Qinshan Phase III nuclear power plant in 2009. For cobalt-60 production, the reactor's full complement of stainless steel adjusters is replaced with neutronically equivalent cobalt-59 adjusters, which are essentially invisible to reactor operation. With its very high neutron flux and optimized fuel burn-up, the CANDU has a very high cobalt-60 production rate in a relatively short time. This makes CANDU an excellent vehicle for bulk cobalt-60 production. Several studies have been performed to produce cobalt-60 using adjuster rod at Wolsong nuclear power plant. This study proposed new concept for producing cobalt-60 and performed the feasibility study. Bundle typed cobalt loading concept is proposed and evaluated the feasibility to fuel management without physics and system design change. The requirement to load cobalt bundle to the core was considered and several channels are nominated. The production of cobalt-60 source is very depend on the flux level and burnup directly.

    The search of an optimization of the French electronuclear network operations leads to a necessary optimization of the core performances. All the economic studies performed by the utilities had shown that there is a real gain to minimize shut down periods for refueling. So, increasing the cycle length from 12 to 18 months will present a gain of shut down for a three years operation period. The theoretical burnable absorber will be a fuel admixed material bringing the required initial negative reactivity with a burn-up kinetic well suited to the fuel and allowing the lowest residual penalty as possible. The residual penalty us defined in this case by the non complete burn up of the poison, by the low of fissile material and by the accumulate of residual isotopes or nuclides. Because of the well known use of gadolinium as burnable absorber for BWR`s and PWR`s operations, the search for the best compromise to optimize all the above stress is pointed towards the rare earths. In the nuclides family, considering criteria such as cross sections, natural abundance and availability only five nuclides can play the role as burnable absorbers, namely: gadolinium, samarium, dysprosium, europium and erbium. The study presented here will show that only gadolinium and erbium will be considered to control the reactivity of the PWR`s. (author). 58 refs., 65 figs., 47 tabs.

    A 33-year-old man was admitted 8 hours after voluntary ingestion of 1875 mg of chlorophacinone (C'Operat 750 mL). The examination revealed excitation and nausea, with a normal prothrombin index (PI). Comprehensive testing for abused and therapeutic drugs in blood confirmed chlorophacinone (maximum plasma level: 27.6 mg/L), an antivitamin K (AVK) rodenticide. In a search for easy toxicological management of chlorophacinone poisoning treated by phytomenadione and a cytochrome P450 inducer (phenobarbital), PI and chlorophacinone plasma levels were monitored concomitantly during 17 days. A simple HPLC procedure for the determination of chlorophacinone in human plasma is reported for that purpose. Under phenobarbital 200 mg/day, chlorophacinone exhibited an apparent elimination half-life (3.27 days) shorter than in previously reported cases. If PI is useful for planning phytomenadione treatment and used for therapeutic monitoring of AVK, the chlorophacinone concentrations follow-up may provide a better estimation of the duration of hospitalisation. Chlorophacinone accumulation in target cells or existence of an unidentified metabolite may explain persistence of the hypocoagulability syndrome at low plasmatic concentrations of chlorophacinone. This case illustrates how toxicological management may facilitate toxicokinetics and therapeutic data acquisition.

    Full Text Available Exposure to toxic metals remains a wide spread occupational and environmental problems in world. Due to their widespread use in human activities such as industry, agriculture and even as medicine numerous health risks may be associated with exposure to these substances. Lead, arsenic and cadmium generally interferes with a number of body functions such as the haematopoietic system, central nervous system (CNS, liver and kidneys. Over the past few decades there have been growing awareness and concern that the toxic biochemical and functional effects are occurring at lower level of metal exposure than those that produce overt clinical and pathological signs and symptoms. Despite many years of research we are still far from an effective treatment of chronic heavy metal poisoning. The main therapeutic option for chronic metal poisoning relies in chelation therapy. Chelating agents are capable of linking together metal ions to form complex structures which can be easily excreted from the body. They have been used clinically as antidotes for acute and chronic poisoning. 2, 3-dimercaprol (BAL has long been the mainstay of chelation therapy of lead or arsenic poisoning. Meso 2, 3, -dimercaptosuccinic acid (DMSA has been tried successfully in animals as well as in few cases of human lead or arsenic poisoning. However, one of the major disadvantages of chelation with DMSA has been its inability to remove heavy metal from the intracellular sites because of its lipophobic nature. Further, it does not provide protection in terms of clinical/ biochemical recovery. A new trend in chelation therapy has emerged to use combined treatment. This includes use of structurally different chelating agents or a combination of an antioxidant and a chelator to provide better clinical/biochemical recovery in addition to mobilization of heavy metal form intracellular sites. The present review article attempts to provide update information about the current strategies being

    Full Text Available 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.

    Burnable absorber is used for reducing reactivity swing and power peaking in high performance research reactors. Development of the HANARO fuel element with burnable absorber was started in the U-Mo fuel development program at HANARO, but detailed full core analysis was not performed because the current HANARO fuel management system is uncertain to analysis the HANARO core with burnable absorber. A sophisticated reactor physics system is required to analysis the core. The McCARD code was selected and the detailed McCARD core models, in which the basic HANARO core model was developed by one of the McCARD developers, are used in this study. The development of nuclear fuel requires a long time and correct developing direction especially by the nuclear analysis. This paper presents a preliminary nuclear analysis to promote the fuel development. Based on the developed fuel, the further nuclear analysis will improve reactor performance and safety. Basic nuclear analysis for the HANARO and the AHR were performed for getting the proper fuel elements with burnable absorber. Addition of 0.3 - 0.4% Cd to the fuel meat is promising for the current HANARO fuel element. Small addition of burnable absorber may not change any fuel characteristics of the HANARO fuel element, but various basic tests and irradiation tests at the HANARO core are required.

    We describe a clinical decision support system (CDSS) designed to provide timely information germane to poisoning. The CDSS aids medical decision making through recommendations to clinicians for immediate evaluation. The system is implemented as a rule-based expert system with two major components: the knowledge base and the inference engine. The knowledge base serves as the database which contains relevant poisoning information and rules that are used by the inference engine in making decisions. This expert system accepts signs and symptoms observed from a patient as input and presents a list of possible poisoning types with the corresponding management procedures which may be considered in making the final diagnosis. A knowledge acquisition tool (KAT) that allows toxicological experts to update the knowledge base was also developed. This article describes the architecture of the fully featured system, the design of the CDSS and the KAT as web applications, the utilisation of the inferencing mechanism of C Language Integrated Production System (CLIPS), which is an expert system shell that helps the system in decision-making tasks, the methods used as well as problems encountered. We also present the results obtained after testing the system and propose some recommendations for future work.

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

    Poisons centres throughout Italy and Europe vary considerably in terms of their institutions and organisation. The European Association of Poisons Centres and Clinical Toxicologists (EAPCCT) has laid down the activities that a poisons centre must carry out, specifying minimum and maximum standards required. These directions allow an evaluation of the service provided. In 2002 Milan Poisons Centre began a project aiming to introduce concepts and methodology proper of the quality systems within poisons centres' institutional activity. Concluded, the project resulted in the centre's certification and the documentation of its procedures: this may now contribute to help define the status and activity of poisons centres in Italy.

    Reducing critical boron concentration in a commercial pressurized water reactor core offers many advantages in view of safety and economics. This paper presents a preliminary investigation of a reduced-boron pressurized water reactor core to achieve a clearly negative moderator temperature coefficient at hot zero power using the newly-proposed 'Burnable absorber-Integrated Guide Thimble' (BigT) absorbers. The reference core is based on a commercial OPR1000 equilibrium configuration. The reduced-boron ORP1000 configuration was determined by simply replacing commercial gadolinia-based burnable absorbers with the optimized BigT-loaded design. The equilibrium cores in this study were directly searched via repetitive Monte Carlo depletion calculations until convergence. The results demonstrate that, with the same fuel management scheme as in the reference core, application of the BigT absorbers can effectively reduce the critical boron concentration at the beginning of cycle by about 65 ppm. More crucially, the analyses indicate promising potential of the reduced-boron OPR1000 core with the BigT absorbers, as its moderator temperature coefficient at the beginning of cycle is clearly more negative and all other vital neutronic parameters are within practical safety limits. All simulations were completed using the Monte Carlo Serpent code with the ENDF/B-VII.0 library.

  20. Ciguatera poisoning: a global issue with common management problems.

    2001-12-01

    Ciguatera poisoning, a toxinological syndrome comprising an enigmatic mixture of gastrointestinal, neurocutaneous and constitutional symptoms, is a common food-borne illness related to contaminated fish consumption. As many as 50000 cases worldwide are reported annually, and the condition is endemic in tropical and subtropical regions of the Pacific Basin, Indian Ocean and Caribbean. Isolated outbreaks occur sporadically but with increasing frequency in temperate areas such as Europe and North America. Increase in travel between temperate countries and endemic areas and importation of susceptible fish has led to its encroachment into regions of the world where ciguatera has previously been rarely encountered. In the developed world, ciguatera poses a public health threat due to delayed or missed diagnosis. Ciguatera is frequently encountered in Australia. Sporadic cases are often misdiagnosed or not medically attended to, leading to persistent or recurrent debilitating symptoms lasting months to years. Without treatment, distinctive neurologic symptoms persist, occasionally being mistaken for multiple sclerosis. Constitutional symptoms may be misdiagnosed as chronic fatigue syndrome. A common source outbreak is easier to recognize and therefore notify to public health organizations. We present a case series of four adult tourists who developed ciguatera poisoning after consuming contaminated fish in Vanuatu. All responded well to intravenous mannitol. This is in contrast to a fifth patient who developed symptoms suggestive of ciguatoxicity in the same week as the index cases but actually had staphylococcal endocarditis with bacteraemia. In addition to a lack of response to mannitol, clinical and laboratory indices of sepsis were present in this patient. Apart from ciguatera, acute gastroenteritis followed by neurological symptoms may be due to paralytic or neurotoxic shellfish poisoning, scombroid and pufferfish toxicity, botulism, enterovirus 71, toxidromes and

    Full Text Available Background: Paraquat (PQ poisoning is highly fatal; and therefore, clinicians should be familiar with prompt approach to and poor prognostic features of this type of poisoning. Hence, in this study, clinical profile, management and outcome of a series of patients with PQ poisoning are presented. Methods: A retrospective review of medical records of patients poisoned with PQ who were treated at Clinical Toxicology Department of Razi Hospital in Ahwaz, Iran during 2005 to 2008 was performed.  Results: Forty-two patients (66.7% men were studied. Majority of them (83.3% were between 15-29 years of age. Most of PQ poisonings occurred following suicidal ideation (39 patients; 92.9%. The most common on-admission clinical findings of the patients were vomiting (69% and respiratory distress (47.6%. Activated charcoal was given to 35 patients (83.3%. N-acetyl cysteine (100 mg/kg IV stat, vitamin E (100 IU daily IV and vitamin C (500 mg daily IV were given to all patients. Exploratory endoscopy for plausible mucosal ulcers was carried out for 23 patients (54.8%. Pantoprazole (40 mg twice daily was given to all patients and for 7 patients with upper gastrointestinal (GI irritation and GI bleeding, higher doses of pantoprazole (8 mg/hour was administered. All patients received pulse therapy with methyl prednisolone (1g daily for three days and cyclophosphamide (15 mg/kg daily for two days. Twenty patients died. Comparing death and survival, death was significantly higher in patients with respiratory distress (100 vs. 0.0 %, P < 0.001, renal dysfunction (85.0 vs. 9.1 %, P < 0.001 and hepatic dysfunction (75.0 vs. 4.5 %, P < 0.001. Conclusion: PQ poisoning creates a life-threatening clinical situation, which requires quick and proper treatment. Based on this research, mortality rate is greater in the presence of renal, hepatic and respiratory dysfunction.

    1999-06-01

    In vitro experiments were performed to investigated the extend of adsorption of ciprofloxacin to kaolin, magnesium trislilicate and to a starch obtained from the tubers of Tacca involucrata (Tacca starch) and to explore the effect of varying pH on this adsorption. Activated charcoal, a standard adsorbent and antidote in the management of poisoning due to a variety of chemical agents was employed as a comparing standard. The results of the study indicate that kaolin and magnesium trisilicate adsorbed ciprofloxacin effectively while the adsorption of the drug on the starch was relatively low. Adsorption was dependent upon the quantity of the adsorbed used. Kaolin or magnesium trisilicate could serve as an effective antidotal alternative to activated charcoal in the management of ciprofloxacin poisoning. Except in cases of poisoning due to ciprofloxacin, the concurrent administration of the drug with kaolin or magnesium trisilicate may be contraindicated. Tacca starch, however, may not really be recommended for the management of ciprofloxacin poisoning.

    Seven hundred and seventy-six cases were studied during a six-month period to see if induction of emesis could be successfully managed at home by telephone. Emesis was successful in 98.8% of cases. In 6.7% of all cases, symptoms were found at 4-hour follow-up that were referrable to the ingestion, but all were considered to be of minor consequence. No complications of vomiting occurred. Twenty-four hour follow-up investigation indicated no significant complications of induction of emesis or complications from managing the patient by telephone. It is our conclusion that, with appropriate telephone supervision, home-induced emesis of ingestions expected to produce mild to moderate symptoms is as effective as emergency room or physician office management of cases. Furthermore, the absence of adverse affects of complications arising from the induction of emesis at home in our cases confirms that this form of management is quite safe.

    The use of an extracorporeal treatment (ECTR) in a poisoned patient may be life-saving in a limited number of scenarios. The decision-processes surrounding the use of ECTR in poisoning is complex: most nephrologists are not trained to assess a poisoned patient while clinical toxicologists rarely prescribe ECTRs. Deciding on which ECTR is most appropriate for a poison requires a good understanding of the poison's physicochemical and pharmacokinetic properties. Further, a detailed understanding of the capabilities and limitations of the different ECTRs can be useful to select the most appropriate ECTR for a given clinical situation. This manuscript provides a stepwise approach to assess the usefulness of ECTRs in poisoning.

    2013-05-01

    Full Text Available Poisoning morbidity and mortality is high in the developing world. Systems for care of poisoned patients differ markedly between countries. In this paper a comparison of two very different systems for the care of poisoned patients, is presented. Specifically, the role of poison centers and poison treatment centers in the US and Iran are contrasted. A systematic literature search was undertaken utilizing the PubMed, Scopus, and Google Scholar and the keywords “poison centers”, “treatment” “Iran” “United States of America” and 100 publications were identified. From these, relevant data were found in 23 publications. The information was double-checked and data were summarized herein.We find that the system of the care of poisoned patients relies heavily on certified poison centers in the US and that only a few hospitals have well developed medical toxicology services. In contrast, in Iran, the poison center system is somehow less developed and the care of poisoned patients is provided in centralized high volume hospital poison units.Although both the US and Iran have highly developed systems for the care of poisoned patients they are distinctly different. Comparative studies based on these systems could provide important data for developing countries with more rudimentary poison control and treatment facilities.

    This project will demonstrate the feasibility of using atomic layer deposition (ALD) to apply ultrathin neutron-absorbing, corrosion-resistant layers consisting of ceramics, metals, or combinations thereof, on particles for enhanced nuclear fuel pellets. Current pellet coating technology utilizes chemical vapor deposition (CVD) in a fluidized bed reactor to deposit thick, porous layers of C (or PyC) and SiC. These graphitic/carbide materials degrade over time owing to fission product bombardment, active oxidation, thermal management issues, and long-term irradiation effects. ALD can be used to deposit potential ceramic barrier materials of interest, including ZrO{sub 2}, Y{sub 2}O{sub 3}:ZrO{sub 2} (YSZ), Al{sub 2}O{sub 3}, and TiO{sub 2}, or neutron-absorbing materials, namely B (in BN or B{sub 2}O{sub 3}) and Gd (in Gd{sub 2}O{sub 3}).

    The most important tasks of modern analytic toxicology can be summarized as follows: identification and quantification of toxicants potentially responsible for the intoxication of an emergency patient; confirmation or exclusion of poisoning diagnoses; grading and prognosis of an intoxication; monitoring of elimination therapies; testing for drugs of abuse; exclusion of the presence of central depressants before organ explanation or discontinuation of life support; checking the compliance of patients with prescribed drug therapy; therapeutic drug monitoring. The interpretation of toxicologic results is one of the most difficult tasks in toxicology. It is not always possible to relate symptoms and blood concentrations of drugs and poisons. In many cases, it is necessary to monitor biochemical parameters in the management of poisoned patient.

    Full Text Available Para-chloronitrobenzene (p-CNB, a hazardous and toxic substance, is widely used as an intermediary in chemical industries. p-CNB can cause methaemoglobinaemia due to electron-withdrawing properties of the nitro and chlorine groups. We present a case of a 23-year-old man suffering from thermal burns and p-CNB poisoning. In this case, severe methaemoglobinaemia was caused by the absorption of p-CNB through the burn wounds. Despite active treatment, such as the antidote of methylene blue, the patient’s methaemoglobinaemia progressed, with slowly increasing methaemoglobin (MetHb level. This case highlights the complexity and difficulty of managing this type of injury. To our knowledge, this case can be the first case report describing methaemoglobinaemia induced by p-CNB in a patient with thermal burns.

    A review of US poison center data for 2004 showed over 8,000 ingestions of methylphenidate. A guideline that determines the conditions for emergency department referral and prehospital care could potentially optimize patient outcome, avoid unnecessary emergency department visits, reduce health care costs, and reduce life disruption for patients and caregivers. An evidence-based expert consensus process was used to create the guideline. Relevant articles were abstracted by a trained physician researcher. The first draft of the guideline was created by the lead author. The entire panel discussed and refined the guideline before distribution to secondary reviewers for comment. The panel then made changes based on the secondary review comments. The objective of this guideline is to assist poison center personnel in the appropriate out-of-hospital triage and initial out-of-hospital management of patients with suspected ingestions of methylphenidate by 1) describing the process by which a specialist in poison information should evaluate an exposure to methylphenidate, 2) identifying the key decision elements in managing cases of methylphenidate ingestion, 3) providing clear and practical recommendations that reflect the current state of knowledge, and 4) identifying needs for research. This review focuses on the ingestion of more than a single therapeutic dose of methylphenidate and the effects of an overdose and is based on an assessment of current scientific and clinical information. The expert consensus panel recognizes that specific patient care decisions may be at variance with this guideline and are the prerogative of the patient and the health professionals providing care, considering all of the circumstances involved. This guideline does not substitute for clinical judgment. Recommendations are in chronological order of likely clinical use. The grade of recommendation is in parentheses. 1) All patients with suicidal intent, intentional abuse, or in cases in which

  6. Effects of limestone petrography and calcite microstructure on OPC clinker raw meals burnability

    Science.gov (United States)

    Galimberti, Matteo; Marinoni, Nicoletta; Della Porta, Giovanna; Marchi, Maurizio; Dapiaggi, Monica

    2016-12-01

    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.

    Ciguatera Fish Poisoning (CFP) is the most frequently reported seafood-toxin illness in the world. It causes substantial human health, social, and economic impacts. The illness produces a complex array of gastrointestinal, neurological and neuropsychological, and cardiovascular symptoms, which may last days, weeks, or months. This paper is a general review of CFP including the human health effects of exposure to ciguatoxins (CTXs), diagnosis, human pathophysiology of CFP, treatment, detection of CTXs in fish, epidemiology of the illness, global dimensions, prevention, future directions, and recommendations for clinicians and patients. It updates and expands upon the previous review of CFP published by Friedman et al. (2008) and addresses new insights and relevant emerging global themes such as climate and environmental change, international market issues, and socioeconomic impacts of CFP. It also provides a proposed universal case definition for CFP designed to account for the variability in symptom presentation across different geographic regions. Information that is important but unchanged since the previous review has been reiterated. This article is intended for a broad audience, including resource and fishery managers, commercial and recreational fishers, public health officials, medical professionals, and other interested parties.

    Objective: To provide a management approach for adults with calcium channel blocker poisoning. Data Sources, Study Selection, and Data Extraction: Following the Appraisal of Guidelines for Research & Evaluation II instrument, initial voting statements were constructed based on summaries outlining the evidence, risks, and benefits. Data Synthesis: We recommend 1) for asymptomatic patients, observation and consideration of decontamination following a potentially toxic calcium channel blocker ingestion (1D); 2) as first-line therapies (prioritized based on desired effect), IV calcium (1D), high-dose insulin therapy (1D–2D), and norepinephrine and/or epinephrine (1D). We also suggest dobutamine or epinephrine in the presence of cardiogenic shock (2D) and atropine in the presence of symptomatic bradycardia or conduction disturbance (2D); 3) in patients refractory to the first-line treatments, we suggest incremental doses of high-dose insulin therapy if myocardial dysfunction is present (2D), IV lipid-emulsion therapy (2D), and using a pacemaker in the presence of unstable bradycardia or high-grade arteriovenous block without significant alteration in cardiac inotropism (2D); 4) in patients with refractory shock or who are periarrest, we recommend incremental doses of high-dose insulin (1D) and IV lipid-emulsion therapy (1D) if not already tried. We suggest venoarterial extracorporeal membrane oxygenation, if available, when refractory shock has a significant cardiogenic component (2D), and using pacemaker in the presence of unstable bradycardia or high-grade arteriovenous block in the absence of myocardial dysfunction (2D) if not already tried; 5) in patients with cardiac arrest, we recommend IV calcium in addition to the standard advanced cardiac life-support (1D), lipid-emulsion therapy (1D), and we suggest venoarterial extracorporeal membrane oxygenation if available (2D). Conclusion: We offer recommendations for the stepwise management of calcium channel blocker

    Background: Organophosphorus compound poisoning (OPCP) is a major public health problem in developing countries like India. Atropine and oximes remain the main-stay of management. Magnesium sulfate (MgSO4) has shown benefit in the management of OPCP. Aims: This study was designed to assess the effect of MgSO4 on outcome in OPCP patients admitted to Intensive Care Unit (ICU). Settings and Design: Double-blind prospective randomized clinical trial in an ICU of tertiary care institution. Methods: One hundred patients (50 in each group) of OPCP, confirmed by history and syndrome of OPCP with low plasma pseudocholinesterase, aged between 18 and 60 years were studied. Magnesium group (Group M) received 4 g of 20% MgSO4 infusion over 30 min at admission to ICU, control group (Group C) received normal saline placebo in the same manner. Patients were assessed for the need for intubation, requirement of atropine, duration of mechanical ventilation, duration of ICU stay, and its effect on mortality. Statistical Analysis: Chi-square test and Fisher's exact test for categorical data, independent sample t-test, and paired t-test for nominal data. Results: Demographics and basal serum magnesium levels were comparable. Atropine requirement was higher in Group C (74.82 ± 22.39 mg) compared to Group M (53.11 ± 45.83 mg) (P < 0.001). A total of 33 patients in Group C and 23 patients in Group M required intubation, respectively (P = 0.043). The mean duration of mechanical ventilation was 4.51 ± 2 days in Group C compared to 4.13 ± 1.6 days in Group M (P = 0.45). ICU stay was 5.36 ± 2.018 days in Group C compared to 4.54 ± 1.581 days in Group M (P = 0.026). There was no significant difference in mortality between the groups. Conclusion: Four grams of MgSO4 given to OPCP patients within 24 h of admission to ICU, decreases atropine requirement, need for intubation, and ICU stay.

    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 due 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.

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

    Mercury poisoning cases have been reported in many parts of the world, resulting in many deaths every year. Mercury compounds are classified in different chemical types such as elemental, inorganic and organic forms. Long term exposure to mercury compounds from different sources e.g. water, food, soil and air lead to toxic effects on cardiovascular, pulmonary, urinary, gastrointestinal, neurological systems and skin. Mercury level can be measured in plasma, urine, feces and hair samples. Urinary concentration is a good indicator of poisoning of elemental and inorganic mercury, but organic mercury (e.g. methyl mercury) can be detected easily in feces. Gold nanoparticles (AuNPs) are a rapid, cheap and sensitive method for detection of thymine bound mercuric ions. Silver nanoparticles are used as a sensitive detector of low concentration Hg2+ ions in homogeneous aqueous solutions. Besides supportive therapy, British anti lewisite, dimercaprol (BAL), 2,3-dimercaptosuccinic acid (DMSA. succimer) and dimercaptopropanesulfoxid acid (DMPS) are currently used as chelating agents in mercury poisoning. Natural biologic scavengers such as algae, azolla and other aquatic plants possess the ability to uptake mercury traces from the environment.

    A 44-year-old man took the tuber of Alocasia macronhiza by mistake. Several minutes after ingestion of the tuber, he presented with numbness of lip, sore throat, nausea, vomiting, salivation, dyspnea, and dysphonia. Twenty minutes after poisoning, he was hospitalized and diagnosed as having acute laryngeal edema. He received diphenhydramine 20 mg and dexamethasone 5 mg via IV push, followed by an IV infusion of dexaroethasone 10 mg. Meanwhile oxygen inhalation, liver protective treatment, and other symptomatic treatment were given. Five hours after poisoning, his symptoms gradually resolved and, 50 days later, he recovered. Alocasia macronhiza is a poisonous plant of Alocasia Sckott in the family Araceae, and it contains sapotoxin and calcium oxalate which can induce neurological and gastrointestinal disorder after ingestion of the plant. The latent period from exposure to onset of symptoms is 10 to 30 minutes and death might occur in patients with severe poisoning. Skin contact or eye contact with Alocasia macronhiza juice can cause pruritus, conjunctivitis, and even blindness. Inhalation of Alocasia macronhiza powder can lead to severe mucosal irritation in the eye, nasal cavity, and throat. Poisoning could be diagnosed by the history of contact with the plant and clinical manifestations. There is no specific antidote for Alocasia macronhiza poisoning and main management is symptomatic treatment.%1例44岁男性误食海芋块根,数分钟后出现口唇麻木、咽喉疼痛、恶心、呕吐、流涎、呼吸困难、发音困难等症状,中毒后20 min入院,诊断为急性喉头水肿.给予静脉推注苯海拉明20 mg、地塞米松5mg和静脉滴注地塞米松10 ng等处理,并行吸氧、保肝等对症治疗.中毒5h后症状逐渐好转,50 d后痊愈.海芋是天南星科海芋属有毒植物,含有皂素毒苷及草酸钙等.口服后可致神经和胃肠系统症状,潜伏期一般为10~30 min,严重者可致死亡;皮肤或者眼接触海芋汁

    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.

    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.

    Poisoning with methanol and ethylene glycol can cause serious morbidity and mortality. Specific treatment involves the use of antidotes (fomepizole or ethanol) with or without extracorporeal elimination techniques. A prospective audit of patients with methanol or ethylene glycol poisoning reported by telephone to the National Poisons Information Service (NPIS) in the UK was conducted during the 2010 calendar year and repeated during the 2012 calendar year. The study was conducted to determine the frequency of clinically significant systemic toxicity and requirement for antidote use and to compare outcomes and rates of adverse reaction and other problems in use between ethanol and fomepizole. The NPIS received 1315 enquiries involving methanol or ethylene glycol, relating to 1070 individual exposures over the 2-year period. Of the 548 enquiries originating from hospitals, 329 involved systemic exposures (enteral or parenteral as opposed to topical exposure), of which 216 (66%) received an antidote (204 for ethylene glycol and 12 for methanol), and 90 (27%) extracorporeal treatment (86 for ethylene glycol and 4 for methanol). Comparing ethanol with fomepizole, adverse reactions (16/131 vs. 2/125, p ethylene glycol or methanol results in hospitalisation at least 2-3 times per week on average in the UK. No difference in outcome was detected between ethanol and fomepizole-treated patients, but ethanol was associated with more frequent adverse reactions.

  16. ATR LEU Monolithic Foil-Type Fuel with Integral Cladding Burnable Absorber – Neutronics Performance Evaluation

    2012-03-01

    The Advanced Test Reactor (ATR), currently operating in the United States, is used for material testing at very high neutron fluxes. Powered with highly enriched uranium (HEU), the ATR has a maximum thermal power rating of 250 MWth. Because of the large test volumes located in high flux areas, the ATR is an ideal candidate for assessing the feasibility of converting HEU driven reactor cores to low-enriched uranium (LEU) cores. The burnable absorber - 10B, was added in the inner and outer plates to reduce the initial excess reactivity, and to improve the peak ratio of the inner/outer heat flux. The present work investigates the LEU Monolithic foil-type fuel with 10B Integral Cladding Burnable Absorber (ICBA) design and evaluates the subsequent neutronics operating effects of this proposed fuel designs. The proposed LEU fuel specification in this work is directly related to both the RERTR LEU Development Program and the Advanced Test Reactor (ATR) LEU Conversion Project at Idaho National Laboratory (INL).

    An analysis model using MICBURN-3/CASMO-3 is established for the enriched gadolinia burnable absorber rods. A homogenized cross section editing code, PROLOG, is modified so that it can handle such a fuel assembly that includes two different types of gadolinia rods. Study shows that Gd-155 and Gd-157 are almost same in suppressing the excess reactivity and it is recommended to enrich both odd number isotopes, Gd-155 and Gd-157. It is estimated that the cycle length increases by 2 days if enriched gadolinia rods are used in the commercial nuclear power plant such as YGN-3 of which the cycle length is assumed 2 years. For the advanced integral reactor SMART in which ultra long cycle length and soluble boron-free operation concept is applied, natural gadolinia burnable absorber rods fail to control the excess reactivity. On the other hand, enriched gadolinia rods are successful in controling the excess reactivity. To minimize power peakings, various placements of gadolinia rods are tested. Also initial reactivity holddown and gadolinia burnout time are parametrized with respect to the number of gadolinia rods and gadolinia weight fractions.

    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.

    2015-10-01

    Amitraz is used as an ectoparasiticide for dogs and cattle. Human poisoning due to amitraz may be misdiagnosed as organophosphate/carbamate (OPC) toxicity, since amitraz poisoning shares several clinical features (miosis, bradycardia and hypotension) encountered with OPC poisoning. A 19-year-old man with an alleged history of suicidal ingestion of a pesticide presented with drowsiness and was found to have constricted pupils, hypotension and bradycardia. He was diagnosed as a case of OPC poisoning and was treated with atropine and pralidoxime prior to presentation to our centre. Absence of a hypersecretory state, and the presence of hyperglycaemia and hypothermia along with a normal serum cholinesterase level suggested an alternate possibility. Retrieval of the poison container confirmed the diagnosis of amitraz poisoning. The patient made a rapid recovery with supportive management. Clinician awareness is key to successful management of this poisoning, which carries a good prognosis.

    The starting microstructure of a fuel plate will impact how it performs during irradiation. As a result, microstructural characterization has been performed on as-fabricated monolithic fuel plates to determine the changes in fuel plate microstructure that may result from changes in fabrication parameters. Particular focus has been given to the fuel plate U-10Mo/Zr and Zr/AA6061 cladding interfaces, since the integrity of these interfaces will play a big role in determining the overall performance of the fuel plate during irradiation. In addition, burnable absorber materials for potential incorporation into monolithic fuel plates have been characterized to identify their as-fabricated microstructures. This information will be important when trying to understand the PIE data from fuel plates with burnable absorbers that are irradiated in future irradiation experiments. This paper will focus on the microstructures observed using optical metallography, X-ray diffraction, and scanning and transmission electron microscopy for monolithic fuel plates exposed to different fabrication parameters and for as-fabricated burnable absorber materials.

  15. Incorporation of Integral Fuel Burnable Absorbers Boron and Gadolinium into Zirconium-Alloy Fuel Clad Material

    Long-lived fuels require the use of higher enrichments of 235U or other fissile materials. Such high levels of fissile material lead to excessive fuel activity at the beginning of life. To counteract this excessive activity, integral fuel burnable absorbers (IFBA) are added to some rods in the fuel assembly. The two commonly used IFBA elements are gadolinium, which is added as gadolinium-oxide to the UO2 powder, and boron, which is applied as a zirconium-diboride coating on the UO2 pellets using plasma spraying or chemical vapor deposition techniques. The incorporation of IFBA into the fuel has to be performed in a nuclear-regulated facility that is physically separated from the main plant. These operations tend to be very costly because of their small volume and can add from 20 to 30% to the manufacturing cost of the fuel. Other manufacturing issues that impact cost and performance are maintaining the correct levels of dosing, the reduction in fuel melting point due to gadolinium-oxide additions, and parasitic neutron absorption at fuel's end-of-life. The goal of the proposed research is to develop an alternative approach that involves incorporation of boron or gadolinium into the outer surface of the fuel cladding material rather than as an additive to the fuel pellets. This paradigm shift will allow for the introduction of the IFBA in a non-nuclear regulated environment and will obviate the necessity of additional handling and processing of the fuel pellets. This could represent significant cost savings and potentially lead to greater reproducibility and control of the burnable fuel in the early stages of the reactor operation. The surface alloying is being performed using the IBEST (Ion Beam Surface Treatment) process developed at Sandia National Laboratories. IBEST involves the delivery of energetic ion beam pulses onto the surface of a material, near-surface melting, and rapid solidification. The non-equilibrium nature of such processing allows for

    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.

Cycle length increases by 8 days if enriched gadolinia rods are used in the commercial nuclear power plant such as YGN-3 with 2 year-cycle-length. The nuclear characteristics such as soluble boron concentrations and power distributions are almost same. The maximum power of the gadolinia rods are slightly increased but gadolinia contents are reduced. For SMART with ultra longer cycle length and soluble boron-free operation concept cycle length can be extended by maximum 90 days due to increased fuel loading.

    Paralytic shellfish poisoning (PSP) is the foodborne intoxication associated with the consumption of seafood contaminated with naturally occurring neurotoxins known as paralytic shellfish toxins. To protect public health from this potentially fatal syndrome, harvesting closures are implemented when toxins exceed the regulatory action level. Traditional monitoring programs established by state shellfish authorities allow for timely closures in state waters with minimal negative impacts on industry. However, such monitoring programs are not feasible in federal offshore waters given their distance from shore and the range of their spatial coverage. Thus innovative management strategies were investigated for these offshore resources. Georges Bank, an offshore resource with an estimated market value of more than 3 billion in Atlantic surfclams and ocean quahogs, has been closed to harvesting following a temporary ban in 1989 and a subsequent indefinite closure in 1990 due to the risk of PSP. As a means of managing this risk and allowing harvest of safe shellfish from this important resource, the Onboard Screening Dockside Testing Protocol (referred to as the Protocol) was developed by the US Food and Drug Administration (FDA), National Marine Fisheries Service (NMFS), state shellfish control authorities, and industry. The Protocol, which sets forth control measures to ensure product safety and public health protection, was endorsed by the Interstate Shellfish Sanitation Conference (ISSC) for pilot testing. Briefly, the pilot study Protocol required that (1) the fishing vessel receive a permit from NMFS to harvest in closed waters, (2) a miniμm of five shellfish samples per intended harvest lot be tested for PSP toxins onboard, and (3) harvesting only occur when the samples tested from the intended fishing area are negative using the Jellett Rapid Tests or Abraxis Shipboard ELISA kits. Finally, product landed under the Protocol was confirmed to be safe for consumption

    Mercury is a widespread heavy metal with potential severe impacts on human health. Exposure conditions to mercury and profile of toxicity among humans depend on the chemical forms of the mercury: elemental or metallic mercury, inorganic or organic mercury compounds. This article aims to reviewing and synthesizing the main knowledge of the mercury toxicity and its organic compounds that clinicians should know. Acute inhalation of metallic or inorganic mercury vapours mainly induces pulmonary diseases, whereas chronic inhalation rather induces neurological or renal disorders (encephalopathy and interstitial or glomerular nephritis). Methylmercury poisonings from intoxicated food occurred among some populations resulting in neurological disorders and developmental troubles for children exposed in utero. Treatment using chelating agents is recommended in case of symptomatic acute mercury intoxication; sometimes it improves the clinical effects of chronic mercury poisoning. Although it is currently rare to encounter situations of severe intoxication, efforts remain necessary to decrease the mercury concentration in the environment and to reduce risk on human health due to low level exposure (dental amalgam, fish contamination by organic mercury compounds…). In case of occupational exposure to mercury and its compounds, some disorders could be compensated in France. Clinicians should work with toxicologists for the diagnosis and treatment of mercury intoxication.

    Full Text Available Plant poisoning is a common presentation in paediatric practice and an important cause of preventable mortality and morbidity in Sri Lanka. The burden of plant poisoning is largely underexplored. The current multicenter study based in rural Sri Lanka assessed clinical profiles, poison related factors, clinical management, complications, outcomes, and risk factors associated with plant poisoning in the paediatric age group. Among 325 children, 57% were male with 64% being below five years of age. 99.4% had ingested the poison. Transfer rate was 66.4%. Most had unintentional poisoning. Commonest poison plant was Jatropha circus and poisoning event happened mostly in home garden. 29% of parents practiced harmful first-aid practices. 32% of children had delayed presentations to which the commonest reason was lack of parental concern regarding urgency of seeking medical care. Presence of poisonous plants in home garden was the strongest risk factor for plant poisoning. Mortality rate was 1.2% and all cases had Oleander poisoning. The study revealed the value of community awareness regarding risk factors and awareness among healthcare workers regarding the mostly benign nature of plant poisoning in children in view of limiting incidence of plant poisoning and reducing expenditure on patient management.

  14. Is Validation of Indigenous Ecological Knowledge a Disrespectful Process? A Case Study of Traditional Fishing Poisons and Invasive Fish Management from the Wet Tropics, Australia

    Directory of Open Access Journals (Sweden)

    2011-09-01

    Full Text Available Despite the growing recognition of the contribution that indigenous ecological knowledge (IEK can make to contemporary 'western' science-based natural resource management (NRM, integration of the two knowledge systems has not reached its full potential in Australia. One explanation is that there is an implicit requirement for IEK to be validated by western scientific knowledge (SK, which has stalled its application and perpetuated the primacy of SK over IEK. Consequently, there is little experience of IEK validation, indigenous peoples' perspectives of the process, and no formal frameworks to achieve mutual and equitable validation of both IEK and SK. In this paper we assess the opportunities and limitations of validation processes using a case study of traditional fishing poisons for invasive fish management in the Wet Tropics World Heritage Area of Australia. The study was conducted within a coresearch approach between the Aboriginal holders of the IEK, who are among the paper's authors, and science-based biologists. We jointly carried out scientific laboratory trials that demonstrated that fishing poisons are effective at immobilizing invasive tilapia. Retrospective interviews with indigenous coresearchers showed that they did not find the experience of validation disrespectful, but instead empowering and necessary for their IEK to be understood and appreciated by scientists and included in NRM. Based on our experiences and knowledge of socialization theory we present a framework for the potential future design of collaborative validation processes to facilitate the integration of IEK into mainstream NRM, and the acceptance of SK within indigenous communities in Australia.

  15. Ciguatera poisoning.

    Achaibar, Kira C; Moore, Simon; Bain, Peter G

    2007-10-01

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

    Full Text Available El presente artículo hace una revisión del manejo clínico de la intoxicación por plomo en la niñez. Se menciona las definiciones de las diferentes técnicas de medición usadas para la determinación de plomo, y se destacan sus ventajas y posibles limitaciones. La medición de los niveles de plomo sanguíneo puede realizarse utilizando muestra de sangre anticoagulada por espectrofotometría de absorción atómica voltametría anódica. Sin embargo, un método más eficiente para medir las concentraciones de plomo en hueso es mediante fluorescencia de Rayos X o para la determinación sistémica en un nivel bioquímico una técnica adecuada es la determinación de los niveles de plomo en orina. El tratamiento incluye la eliminación de la fuente de exposición, cambios en los hábitos de los niños y una dieta adecuada en calcio y hierro. La quelación con edetato de calcio y succimer elimina el plomo del esqueleto, el cual es eliminado por riñón; puede salvar vidas cuando la intoxicación es importante, y existe una reducción a corto plazo seguida de un aumento subsecuente de los niveles de plomo sanguíneo. En casos graves suele requerirse de dosis repetidas. La terapia de quelación puede ser necesaria en casos de niveles de plomo sanguíneo por arriba de 45 µg/dl. La quelación reduce los niveles de plomo sanguíneo y los síntomas asociados, sin embargo, la disminución cognoscitiva puede ser irreversible, por lo que la utilización de medidas preventivas es mucho mejor que las de curación.This paper reviews the clinical management of children with lead poisoning. A first step is to define the measures to be used in their assessment and be aware of the limitations. Measurements of blood lead levels can be made on anti-coagulated whole blood samples using either: atomic absorption spectroscopy or anodic stripping voltametry. However a more accurate method is fluorescent RX'ray of the skeleton or systematic biochemical tests of lead

    This study was conducted to evaluate the availability of antidotes/key emergency drugs in tertiary care hospitals of the Punjab province, and to assess the knowledge of health care professionals in the stocking and administration of antidotes in the proper management of poisoning cases. Seventeen (n=17) tertiary care hospitals of Punjab Pakistan were selected. Two performas (A and B) were designed for 26 antidotes/key emergency drugs and given to the hospital pharmacists and physicians respectively. It was observed that Activated Charcoal, being the universal antidote was found only in 6 hospitals (41%). Digoxin Immune Fab, Edentate Calcium disodium and Glucagon were not available in emergency department of any hospital and even not included in the formulary of any hospital. About 80% pharmacists were aware of the method of preparation of Activated Charcoal and 85% physicians were familiar with its route of administration. Data showed that tertiary care hospitals of Punjab do not stock antidotes according to national drug policy. Moreover the study strongly suggests the development of health care centers and professional by organizing antidote awareness programs, continuous education and record keeping of poisonous cases and availability of emergency drugs around the clock.

    An analysis model using MICBURN-3/CASMO-3 is established for the enriched gadolinia burnable absorber rods. A homogenized cross section editing code, PROLOG, is modified so that it can handle such a fuel assembly that includes two different types of gadolinia rods. Study shows that Gd-155 and Gd-157 are almost same in suppressing the excess reactivity and it is recommended to enrich both odd number isotopes, Gd-155 and Gd-157. It is estimated that the cycle length increases by 2 days if enriched gadolinia rods are used in the commercial nuclear power plant such as YGN-3 of which the cycle length is assumed 2 years. For the advanced integral reactor SMART in which ultra long cycle length and soluble boron-free operation concept is applied, natural gadolinia burnable absorber rods fail to control the excess reactivity. On the other hand, enriched gadolinia rods are successful in controling the excess reactivity. To minimize power peakings, various placements of gadolinia rods are tested. Also initial reactivity holddown and gadolinia burnout time are parametrized with respect to the number of gadolinia rods and gadolinia weight fractions.

    We present two events of carbon monoxide (CO) poisoning, which spread out through ventilation pipes to kill or injure neighbors. This is a previously undocumented poisoning process. In the first event, three people died and eight others suffered CO poisoning from a gas-powered water heater in an apartment building. Similar to the first event, three people expired and three others were injured by CO poisoning in the second event. We subsequently determined the cause of these tragedies were due to obstructions at the openings of ventilation pipes. CO is one of the most common causes of poisoning worldwide and these cases often result in tragedy. Early recognition of CO poisoning resulting from obstructed ventilation pipes will facilitate proper management and prevent possible lethal disasters. Additionally, all clinicians and other paramedical personnel ought to raise the suspicion of chemical-related casualties when encountering clusters of patients from a single locale.

    Full Text Available Poisoning is one of the commonest modes of suicide in India. Supervasmol poisoning is one of the commonest modes of suicidal attempt in our region. The common cause for consumption of hair dye is by suicidal intent or accidental oral ingestion. There is no specific antidote for Supervasmol poisoning. Management is only symptomatic and supportive with emergency tracheostomy in majority of cases. Hence, we conducted this study to emphasize the role of ENT surgeon in Supervasmol poisoning. STUDY DESIGN Prospective study. MATERIALS AND METHODS We present a total of 79 cases of Supervasmol poisoning who attended the Emergency Department of Narayana Medical College and General Hospital, Nellore. RESULTS All patients were between age group 15-35 yrs. Females are more than males. More patients were in second decade; 55 cases presented in acute phase, 51 patients underwent tracheostomy and four patients were brought dead. CONCLUSION Emergency tracheostomy is a life saving measure in severe stridor

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

    Venomous snakebite is an emergency condition with high morbidity and mortality in childhood. Nearly all venomous snakes in Turkey are members of the Viperidae family and show poisonous local and hematotoxic effects. A total of 77 children (mean age 9.9 +/- 2.9 years; age range 3-14 years) with venomous snakebites were investigated. General characteristics of the children, species of the snakes, localization of the bite, clinical and laboratory findings, treatment approaches, complications and prognosis were evaluated. The male to female ratio was 1.4. Ninety-one per cent of cases were from rural areas. Most of the bites were seen in May and June. Mean duration between snakebites and admissions to our department was 13 +/- 6.5 h. According to a clinical grading score, 57.1% of patients presented to us as grade II. Mean leukocyte count, aspartate aminotransferase, lactate dehydrogenase, creatinine phosphokinase and protrombin time levels were above the normal ranges and mean activated partial tromboplastin time was below the normal range. Platelet counts inversely correlated with the grading score and duration of hospitalization. The most common complication that occurred during the treatment was tissue necrosis (13%). The mean hospital stay time was 6.3 +/- 6 days. Three children with disseminated intravascular coagulation died. Fasciotomies were performed to seven (9.1%) children due to compartment syndrome. Of 10 children with tissue necrosis, three (3.9%) had finger amputation and seven (9.1%) had toe amputation. Higher grading score on admission, platelet count below 120 000/mm3, AST over 50 IU/L and existence of evident ecchymosis were found as significant risk factors for development of serious complications by logistic regression analysis. Snakebite poisoning is an emergency medical condition that is particularly important in childhood. The envenomations are still considerable public health problems with a high morbidity and mortality in rural areas of Turkey.

    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.

  12. Cleistanthus collinus poisoning

    Anugrah Chrispal

    2012-01-01

    Full Text Available Cleistanthus collinus, a toxic shrub, is used for deliberate self-harm in rural South India. MEDLINE (PUBMED and Google were searched for published papers using the search/ MeSH terms "Cleistanthus collinus," "Euphorbiaceae," "Diphyllin," "Cleistanthin A," Cleistanthin B" and "Oduvanthalai." Non-indexed journals and abstracts were searched by tracing citations in published papers. The toxic principles in the leaf include arylnaphthalene lignan lactones - Diphyllin and its glycoside derivatives Cleistanthin A and B. Toxin effect in animal models demonstrate neuromuscular blockade with muscle weakness, distal renal tubular acidosis (dRTA and type 2 respiratory failure with conflicting evidence of cardiac involvement. Studies suggest a likely inhibition of thiol/thiol enzymes by the lignan-lactones, depletion of glutathione and ATPases in tissues. V-type H+ ATPase inhibition in the renal tubule has been demonstrated. Mortality occurs in up to 40% of C. collinus poisonings. Human toxicity results in renal tubular dysfunction, commonly dRTA, with resultant hypokalemia and normal anion gap metabolic acidosis. Aggressive management of these metabolic derangements is crucial. Acute respiratory distress syndrome (ARDS is seen in severe cases. Cardiac rhythm abnormalities have been demonstrated in a number of clinical studies, though the role of temporary cardiac pacemakers in reducing mortality is uncertain. Consumption of decoctions of C. collinus leaves, hypokalemia, renal failure, severe metabolic acidosis, ARDS and cardiac arrhythmias occur in severe poisonings and predict mortality. Further study is essential to delineate mechanisms of organ injury and interventions, including antidotes, which will reduce mortality.

    Burnable absorbers are not used in current operating WWERs, but in order to optimize the fuel cycle and enhance operational safety, one should also introduce gadolinium or a similar burnable absorber in these reactors. For this purpose adequate tools for properly calculating local effects in hexagonal geometries should be developed and validated. The present gives main results in validating the WIMS-D/4 lattice code for Gd burnable absorber bearing WWER lattices. To validate the code experimental and calculational benchmarks proposed in a IAEA Coordinated Research Program were solved. A code system for the optimization of the Gd axial distribution in a WWER reactor was developed and it also presented here. (author)

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

    Results: The original search yielded 239 articles, of which 52 articles described human cases. After following the inclusion and exclusion criteria, 32 studies describing 310 cases (151 females, 175 children of human poisoning with amitraz were included in this systematic review. The most commonly reported clinical features of amitraz poisoning were altered sensorium, miosis, hyperglycaemia, bradycardia, vomiting, respiratory failure, hypotension and hypothermia. Amitraz poisoning carried a good prognosis with only six reported deaths (case fatality rate, 1.9%. Nearly 20 and 11.9 per cent of the patients required mechanical ventilation and inotropic support, respectively. The role of decontamination methods, namely, gastric lavage and activated charcoal was unclear. Interpretation & conclusions: Our review shows that amitraz is an important agent for accidental or suicidal poisoning in both adults and children. It has a good prognosis with supportive management.

    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. PMID:28049252

    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

    Full Text Available Acute organic insecticide poisoning is a major health problem all over the world, particularly in the developing countries, where organophosphates (OPs are the most common suicidal poisons with high morbidity and mortality and account for a large proportion of patients admitted to intensive care units. Other insecticides less commonly used are organocarbamates, organochlorides, and pyrethroids, which are less toxic and are associated with less morbidity and mortality. Patients with poisoning present with a wide spectrum of gastrointestinal, neurological, and cardiac manifestations. A strong clinical suspicion is necessary to make an early diagnosis and to start appropriate therapy. Treatment is primarily supportive and includes decontamination, anticholinergics, protection of the airway, and cardiac and respiratory support. The use of oximes has been controversial and may be associated with higher mortality owing to a higher incidence of type-II paralysis. They may have other toxic side effects. This paper reviews the literature on OP poisoning.

    1997-01-01

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

  5. Hydroxocobalamin in cyanide poisoning.

    Science.gov (United States)

    Thompson, John P; Marrs, Timothy C

    2012-12-01

    On theoretical grounds, hydroxocobalamin is an attractive antidote for cyanide poisoning as cobalt compounds have the ability to bind and detoxify cyanide. This paper reviews the pharmacokinetic and pharmacodynamic aspects of hydroxocobalamin, its efficacy in human cyanide poisoning and its adverse effects. PubMed was searched for the period 1952 to April 2012. A total of 71 papers were identified in this way; and none was excluded. PHARMACOKINETICS AND PHARMACODYNAMICS: Pharmacokinetic studies in dogs and humans suggest a two-compartment model, with first order elimination kinetics. Pharmacodynamic studies in animals suggest that hydroxocobalamin would be a satisfactory antidote for human cyanide poisoning. EFFICACY IN HUMAN POISONING: There is limited evidence that hydroxocobalamin alone is effective in severe poisoning by cyanide salts. The evidence for the efficacy of hydroxocobalamin in smoke inhalation is complicated by lack of evidence for the importance of cyanide exposure in fires and the effects of other chemicals as well as confounding effects of other therapeutic measures, including hyperbaric oxygen. Evidence that hydroxocobalamin is effective in poisoning due to hydrogen cyanide alone is lacking; extrapolation of efficacy from poisoning by ingested cyanide salts may not be valid. The rate of absorption may be greater with inhaled hydrogen cyanide and the recommended slow intravenous administration of hydroxocobalamin may severely limit its clinical effectiveness in these circumstances. Both animal and human data suggest that hydroxocobalamin is lacking in clinically significant adverse effects. However, in one human volunteer study, delayed but prolonged rashes were observed in one-sixth of subjects, appearing 7 to 25 days after administration of 5 g or more of hydroxocobalamin. Rare adverse effects have included dyspnoea, facial oedema, and urticaria. Limited data on human poisonings with cyanide salts suggest that hydroxocobalamin is an effective

    Accidental poisoning in children shows a trend towards poisoning with various newer drugs and chemicals used in the household. Sixty-one cases of accidental poisoning in children were seen in Sree Avittam Thirunal Hospital, (S.A.T.H.), Trivandrum, South India during the year 1982, constituting 0.61% of the total pediatric admissions. Dapsone poisoning constituted 9.8% of the total accidental poisonings, emphasising the need for safe storage of drugs out of the reach of young children. Dapsone poisoning with resultant methaemoglobinaemia responded well to intravenous ascorbic acid and other supportive measures.

    2013-12-01

    Poisonous plant research in the United States began over 100 years ago as a result of livestock losses from toxic plants as settlers migrated westward with their flocks, herds, and families. Major losses were soon associated with poisonous plants, such as locoweeds, selenium accumulating plants, poison-hemlock, larkspurs, Veratrum, lupines, death camas, water hemlock, and others. Identification of plants associated with poisoning, chemistry of the plants, physiological effects, pathology, diagnosis, and prognosis, why animals eat the plants, and grazing management to mitigate losses became the overarching mission of the current Poisonous Plant Research Laboratory. Additionally, spin-off benefits resulting from the animal research have provided novel compounds, new techniques, and animal models to study human health conditions (biomedical research). The Poisonous Plant Research Laboratory has become an international leader of poisonous plant research as evidenced by the recent completion of the ninth International Symposium on Poisonous Plant Research held July 2013 in Hohhot, Inner Mongolia, China. In this article, we review plants that negatively impact embryo/fetal and neonatal growth and development, with emphasis on those plants that cause birth defects. Although this article focuses on the general aspects of selected groups of plants and their effects on the developing offspring, a companion paper in this volume reviews current understanding of the physiological, biochemical, and molecular mechanisms of toxicoses and teratogenesis.

    We report a prospective and descriptive study about childhood acute poisoning with kerosene in Djibouti. Acute poisoning is a common and stable occurrence in low socioeconomic groups in Africa, where negligence is the main cause of poisoning. The respiratory system was the main target, with 41% of patients having pneumonia, which may become life-threatening, but with low mortality rate. Asymptomatic patients (35%) can be discharged, while those with pulmonary or neurological signs must be admitted for observation and supportive treatment based on oxygen administration. Our study suggests management and provides a discussion for therapeutic options and emphasizes the importance of prevention.

  5. The treatment of acetaminophen poisoning

    Energy Technology Data Exchange (ETDEWEB)

    Prescott, L.F.; Critchley, J.A.

    1983-01-01

    Acetaminophen has become a very popular over-the-counter analgesic in some countries and as a result it is used increasingly as an agent for self-poisoning. Without treatment only a minority of patients develop severe liver damage and 1 to 2% die in hepatic failure. Until Mitchell and his colleagues discovered the biochemical mechanisms of toxicity in 1973 there was no effective treatment. They showed that the metabolic activation of acetaminophen resulted in the formation of a reactive arylating intermediate, and that hepatic reduced glutathione played an essential protective role by preferential conjugation and inactivation of the metabolite. Early treatment with sulphydryl compounds and glutathione precursors has been dramatically effective in preventing liver damage, renal failure, and death following acetaminophen overdosage. It seems likely that these agents act primarily by stimulating glutathione synthesis. Inhibition of the metabolic activation of acetaminophen is another potential therapeutic approach that has not yet been put to the test clinically. The clinical management of acetaminophen poisoning has been transformed and it is particularly gratifying to have effective treatment based on a well established biochemical mechanism of toxicity. It is likely that effective treatment will be developed for toxicity caused through similar mechanisms by other agents.

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

    2014-01-01

    Hemoperfusion is an extracorporeal treatment based on adsorption, historically reserved for the treatment of acute poisonings. Its use was popularized in the 1970s after several in vitro and animal experiments had demonstrated its efficacy, and was even preferred over hemodialysis in the management of overdosed patients. With the advent of new and more efficient dialytic modalities, hemoperfusion is now less frequently performed in the Western world. However, hemoperfusion still remains popular in developing countries. The present article reviews the technique of hemoperfusion, the factors influencing poison clearance through adsorption and its current applications.

    2016-06-01

    Full Text Available BACKGROUND Organophosphate insecticides/pesticides are used widely throughout the world. The organophosphorus poisoning is a very serious condition that needs rapid treatment. Emergent and appropriate management is always desirable to prevent the serious complications and high mortality. In this study, we determine the clinical presentation and outcome of organophosphorus poisoning in our institute. MATERIAL AND METHODS This study carried out in Medicine Department, SIMS, Shimoga, from January 1st, 2016 to April 20th 2016. A total of 100 cases of OP poisoning were studied. We included all patients of organophosphate poisoning presented either with signs of muscarinic involvement or signs of nicotinic involvement. Outcome measured according to W.H.O. classification of severity. RESULT Out of a total 100 patients of organophosphate poisoning were admitted, among these 44% were males and 56% females. Average age was 28.9±8.8 years. Nausea and vomiting was the most common clinical feature found in 93% of the patients followed by salivation seen in 91% and Miosis in 87%. According to W.H.O. Classification for Severity of Organophosphate poisoning. Mild 46%, 37% cases were moderate and 17% were severe. Overall mortality rate was 19%. CONCLUSION Present study shows the importance of WHO staging of severity of organophosphorus compound poisoning as mortality increases with severity. Study also showed that delayed arrival, lack of ICU facility and lack of preliminary management at the early stage are the causes of increased mortality in OP compound poisoning. OP compound poisoning needs rapid diagnosis, early and effective treatment to decrease the severity and mortality. These finding shows need for improvement in primary health care facility to decrease morbidity and mortality

  11. Animal poisoning in Italy: 10 years of epidemiological data from the Poison Control Centre of Milan.

    2012-04-21

    From 2000 to 2010, the Poison Control Centre of Milan (CAV), in collaboration with the University of Milan, Faculty of Veterinary Medicine, Department of Veterinary Sciences and Technologies for Food Safety, Toxicology Section, collected epidemiological information related to animal poisoning and classified it in an organised and computerised data bank. Data recorded were predominantly related to small animals and to some extent to horses, ruminants and other food-production animals. Few calls were registered involving exotics and no information was recorded on wildlife. The dog was reported to be the most common species involved in animal poisoning, and pesticides constituted the primary group of toxicants. In the case of pets, 'drugs' including veterinary parasiticide and drugs for human use constituted the second class of toxicants responsible for poisoning followed by household products, plants, zootoxins and metals. With regard to horses and farm animals, the second group consisted of phytotoxins, even if only episodically. In Italy, published data on this subject are scarce but this information is crucial for better management of the poisoning of domestic animals in an effort to reduce mortality.

  12. Toxidrome-based Approach to Common Poisonings

    Directory of Open Access Journals (Sweden)

    Bruno Mégarbane

    2014-03-01

    Full Text Available Poisoning remains a major cause of hospital admission into the emergency department and intensive care unit. Proper diagnosis is the cornerstone for optimal management of poisoned patients. Since the definitive analytical confirmation of the nature of the toxicant involved in the poisoning cannot be rapidly obtained in the majority of healthcare facilities, diagnosis relies on the medical history and the rigorous clinical examination of the patients well as results of the routine biological tests and the electrocardiogram. Identification of the toxidromes addresses not only the correct diagnosis but also rules out other differential diagnoses. Despite no definitive predictive value, this clinical approach facilitates making decision on empirical treatments and emergent antidotes. Pharmacodynamic tests using specific antidotes including naloxone for opioids and flumazenil for benzodiazepines and its analogues are also helpful to assess the final diagnosis in comatose patients. The objective of this article is to review the toxidrome-based approach to common poisonings before toxicological analysis enables the confirmation of the initially suspected toxic etiology.

Formic acid is diluted and used for coagulation of rubber latex. Easy availability makes formic acid a common poison. The aim of this article is to study the case of formic acid poisoning, its complications and management. Patient was managed symptomatically. Antidote was not used and no nasogastric aspiration was done. Patient had dysphagia; nutrition was maintained with open gastrostomy done on day 5 and subsequent enteral feeding. Measures to prevent anticipated complications were undertaken. Stricture of the esophagus is a common complication leading to long-term morbidity. After initial management, all patients should be on follow-up for prevention and management of strictures. Workers should be educated on complications of formic acid poisoning and easy availability should be curtailed by enforcing remedial measures.

    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.

  18. Arsenic poisoning in livestock.

    Arsenic is an important heavy metal intoxicant to livestock. Arsenical pesticides present significant hazards to animal health. The toxicity of arsenic varies with several factors--its chemical form, oxidation states, solubility. The phenylarsonic compounds are the least toxic and are used as feed additives in swine and poultry rations. However, roxarsone has a higher absolute toxicity than arsanilic acid. The mechanism of action is related to its reaction with sulfhydryl groups values to enzyme function and to its ability to uncouple oxydative phosphorylation. Most animals excrete arsenic quite readily. Toxicoses caused by inorganic and aliphatic organic arsenicals result in a different clinical syndrome than that from the phenylarsonic compounds. Arsenic poisoning may be confused with other types of intoxication. The specific antidote for inorganic arsenical poisoning is dimercaprol (BAL).

  19. Calcium channel blocker poisoning

    Directory of Open Access Journals (Sweden)

    2005-04-01

    Full Text Available Background: Calcium channel blockers act at L-type calcium channels in cardiac and vascular smooth muscles by preventing calcium influx into cells with resultant decrease in vascular tone and cardiac inotropy, chronotropy and dromotropy. Poisoning with calcium channel blockers results in reduced cardiac output, bradycardia, atrioventricular block, hypotension and shock. The findings of hypotension and bradycardia should suggest poisoning with calcium channel blockers.Conclusions: Treatment includes immediate gastric lavage and whole-bowel irrigation in case of ingestion of sustainedrelease products. All patients should receive an activated charcoal orally. Specific treatment includes calcium, glucagone and insulin, which proved especially useful in shocked patients. Supportive care including the use of catecholamines is not always effective. In the setting of failure of pharmacological therapy transvenous pacing, balloon pump and cardiopulmonary by-pass may be necessary.

    for months and years, there is a possibility that every medic can encounter its unusual symptoms, requiring specific treatment. The following toxins cause the poisoning: ciguatoxin, meitotoxin, ostreotoxin, domoic acid and some other unspecified toxins. They are lipid soluble, thermo stable and cannot be decomposed by culinary processing. These toxins have neurotoxic, cardiotoxic, hemolytic properties and cause diarrheic syndrome. Clinical presentation is characterized by average latent period of 12 hours after the consummation, vomiting and diarrhea next 24 hours and neurological symptoms that appear at the beginning of the poisoning with paresthesias along the body, changing feeling of hot and cold, strong myalgia. Disturbances in cardiac rhythm and conduction, strong dehydration or shock are possible in severe cases. Light cases pass over in several days, but, more often the poisoning has a chronic course – from 3-4 months to 1 year, with prevalence of neurologic symptoms: myalgia, paresthesias, skin itching with scratches, depression. The management is not specific and includes stomach lavage with activated charcoal, fluids replacement during the first 24 hours, corticosteroids, antiallergics, high doses of vitamins from group B (Vit. B1, Vit. B6, Vit. B12, mannitol IV, nootropic medicaments, antidepressants and other symptomatic medicaments. The prophylaxis is done by examining every fish with specific test for detecting ciguateratoxin.

    Since natural history museums existed, there have been problems concerning how to protect the collections from damages caused by insects. In 1740s', French Chemist Becoeur started to use arsenic-soap to protect his taxidermy specimens against insects. But in the years of 1770s', it was discovered the terrible strong arsenic poison which was dangerous to human beings. Finally taxidermy specimens leave the use of ar- senic and borax to history and use Eulan in their place.

    Symptomatic arsenic poisoning is not often seen in occupational exposure settings. Attempted homicide and deliberate long-term poisoning have resulted in chronic toxicity. Skin pigmentation changes, palmar and plantar hyperkeratoses, gastrointestinal symptoms, anemia, and liver disease are common. Noncirrhotic portal hypertension with bleeding esophageal varices, splenomegaly, and hypersplenism may occur. A metallic taste, gastrointestinal disturbances, and Mee's lines may be seen. Bone marrow depression is common. 'Blackfoot disease' has been associated with arsenic-contaminated drinking water in Taiwan; Raynaud's phenomenon and acrocyanosis also may occur. Large numbers of persons in areas of India, Pakistan, and several other countries have been chronically poisoned from naturally occurring arsenic in ground water. Toxic delirium and encephalopathy can be present. CCA-treated wood (chromated copper arsenate) is not a health risk unless burned in fireplaces or woodstoves. Peripheral neuropathy may also occur. Workplace exposure or chronic ingestion of arsenic-contaminated water or arsenical medications is associated with development of skin, lung, and other cancers. Treatment may incklude the use of chelating agents such as dimercaprol (BAL), dimercaptosuccinic acid (DMSA), and dimercaptopanesulfonic acid (DMPS).

  6. Organophosphate poisoning : A review

    Full Text Available Organophosphate pesticides are used extensively worldwide, and poisoning by these agents, particularly in developing nations is a public health problem. Organophosphorous nerve agents are still considered as potential threat in both military or terrorism situations. The mechanism of toxicity is the inhibition of acetylcholinesterase, resulting in accumulation of the neurotransmitter acetylcholine and continued stimulation of acetylcholine receptors both in central and peripheral nervous systems. Beside acute cholinergic crisis, organophosphates are capable of producing several subacute or chronic neurological syndromes. The well described intermediate syndrome (IMS emerges 1-4 days after an apparently well treated cholinergic crisis. The standard treatment consists of reactivation of inhibited acetylcholinesterase with an oxime antidote (pralidoxime, obidoxime, HI-6 and Hlo7 and reversal of the biochemical effects of acetylcholine with atropine. The newer oximes HI-6 and Hlo& are much more suitable and efficacious acetylcholinesterase reactivator for severe acute nerve agent induced poisoning than currently used pralidoxime or obidoxime. Patients who receive treatment promptly usually recover from acute toxicity but may suffer from neurologic sequelae.

    2012-01-01

    We present practical poisoning and name-server block- ing attacks on standard DNS resolvers, by off-path, spoofing adversaries. Our attacks exploit large DNS responses that cause IP fragmentation; such long re- sponses are increasingly common, mainly due to the use of DNSSEC. In common scenarios, where DNSSEC is partially or incorrectly deployed, our poisoning attacks allow 'com- plete' domain hijacking. When DNSSEC is fully de- ployed, attacker can force use of fake name server; we show exploits of this allowing off-path traffic analy- sis and covert channel. When using NSEC3 opt-out, attacker can also create fake subdomains, circumvent- ing same origin restrictions. Our attacks circumvent resolver-side defenses, e.g., port randomisation, IP ran- domisation and query randomisation. The (new) name server (NS) blocking attacks force re- solver to use specific name server. This attack allows Degradation of Service, traffic-analysis and covert chan- nel, and also facilitates DNS poisoning. We validated the attac...

    Welch, Kevin D; Panter, Kip E; Gardner, Dale R; Stegelmeier, Bryan L

    2012-06-01

    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

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

    2014-08-01

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

    Carbamate insecticide is a leading cause of poisoning in Thailand. The objective of this study was to characterize the clinical manifestations and modes of occupational exposure in carbamate poisoning cases. We retrospectively studied all the cases of carbamate poisoning due to occupational exposure recorded in the Ramathibodi Poison Center Toxic Exposure Surveillance system during 2005 to 2010. Demographic data, clinical manifestations and severity were analyzed statistically. During the study period, 3,183 cases were identified, of which 170 (5.3%) were deemed to be due to occupational exposure. Ninety-six cases (56.5%) and 35 cases (20.6%) were poisoned by carbofuran and methomyl, respectively. Carbofuran is sold as a 3% grain and applied by sowing; methomyl is sold as a liquid and is applied by spraying. The majority of poisoned patients did not wear personal protective equipment (PPE) while applying the carbamates. The clinical manifestations of occupational carbofuran poisoning recorded were nausea and vomiting (82.3%), headaches (56.3%) and miosis (19.8%). The clinical manifestations of methomyl poisoning were nausea and vomiting (74.3%), headaches (57.1%) and palpitations (11.4%). Most patients in both groups had mild symptoms. Only one case in each group required endotracheal intubation and mechanical ventilation support. There were no deaths and the lengths of hospitalization ranged from 2 hours to 2 days. Occupational carbamate poisoning cases in our series were mostly mild and the patients recovered quickly. There were only rare cases of serious symptoms. Lack of knowledge and inadequate PPE were the major factors contributing to occupational poisoning. Educating agricultural workers about correct precautions and pesticide use could minimize this type of poisoning.

    Full Text Available Organophosphate (OP poisoning is very common form of poisoning in Indian population because of its availability and easy access. Intoxication occurs following the absorption of OP agents through gastrointestinal tract, skin and respiratory tract and rarely by intramuscular or intravenous route. The clinical features depend on the amount of the poison consumed, it′s concentration, the route of administration and the time of instituting therapy. We are reporting a case of an intravenous monochrotophos poisoning, an unusual way of intoxication, which was managed in our ICU.

    Acute poisonings in USA are a leading cause of cardiac arrest, especially in youngsters. Primary survey and cardiopulmonary resuscitation for poisoning is based on ABCDE procedure. One of the most common manifestation of acute poisoning is coma. An open airway should be ensured. Endotracheal intubation should be performed by an experienced person. The mouth-to mouth method of artificial respiration can be applied ultimately. In case of cyanide, hydrogen sulfide, organophosphates and corrosives poisonings a special caution is needed and pocket mask or self-inflating bag with a face mask should be rather used. A quick poison identification and a contact with regional poison information centre regarding patient management are crucial. Different procedures include prolonged cardiopulmonary resuscitation.

  18. Neurology of acute organophosphate poisoning

    2009-01-01

    Full Text Available Acute organophosphate (OP poisoning is one of the most common poisonings in emergency medicine and toxicological practice in some of the less-developed nations in South Asia. Traditionally, OP poisoning comes under the domain of emergency physicians, internists, intensivists, and toxicologists. However, some of the complications following OP poisoning are neurological and involve neurologists. The pathophysiological basis for the clinical manifestations of OP poisoning is inactivation of the enzyme, acetylcholinesterase at the peripheral nicotinic and muscarinic and central nervous system (CNS nerve terminals and junctions. Nicotinic manifestations occur in severe cases and late in the course; these comprise of fasciculations and neuromuscular paralysis. There is a good correlation between the electrophysiological abnormalities and the severity of the clinical manifestations. Neurophysiological abnormalities characteristic of nicotinic junctions (mainly neuromuscular junction dysfunction include: (1 single, supramaximal electrical-stimulus-induced repetitive response/s, (2 decrement-increment response to high frequency (30 Hz repetitive nerve stimulation (RNS, and (3 decremental response to high frequency (30 Hz RNS. Atropine ameliorates muscarinic manifestations. Therapeutic agents that can ameliorate nicotinic manifestations, mainly neuromuscular, are oximes. However, the evidence for this effect is inconclusive. This may be due to the fact that there are several factors that determine the therapeutic effect of oximes. These factors include: The OP compound responsible for poisoning, duration of poisoning, severity of poisoning, and route of exposure. There is also a need to study the effect of oximes on the neurophysiological abnormalities.

    2000-10-01

    Full Text Available Organophosphorous compounds, the anticholinesterases, produce significant morbidity and mortality in India. Although exact estimates are not available, hospital based statistics suggest that nearly half of the admissions to emergency with acute poisoning are due to organophosphates. Following accidental or suicidal exposure, these anticholinesterases lead to three well defined neurological syndromes i.e. initial life threatening acute cholinergic crisis which often requires management in intensive care unit, intermediate syndrome in which cranial nerve palsies, proximal muscle weakness and respiratory muscle weakness are common and patients often require respiratory support and delayed organophosphate induced polyneuropathy. In addition to these three classical neurological syndromes following acute exposure and in some following low dose chronic exposure, several neurobehavioural changes have been observed and these have been termed together as ′chronic organophosphate induced neuropsychiatric disorders′ (COPIND. Organo-phosphate compounds produce significant pesticide related illness in developing countries. There is, thus, a need to determine exact extent of the problem and to develop appropriate strategies to manage these cases with available resources in these countries.

    1979-01-01

    Over a period of years interested individuals have submitted many dead or moribund herons of various species to our laboratory to learn whether the birds had been affected by diseases or organochlorine poisoning. Residue concentrations in carcasses of birds and mammals are considered the best measure of sublethal exposure, whereas residues in brains are best to use for diagnosing death by most organochlorine chemicals.... The purpose of the present paper is to document the occurrence and concentration of organochlorine residues in the brains of herons from various areas in the United States. By comparing these residue concentrations with laboratory-determined diagnostic lethal levels, we conclude that some herons were killed by organochlorine poisoning; others were at least seriously endangered by the residues they carried. Complete results of carcass analyses for these and other herons, as well as further details? on residues in brains, will be reported elsewhere. Overall, we analyzed carcasses or brains of more than 70 herons found dead or moribund and 36 others taken in planned collections. Residue levels in carcasses of many herons were not high enough to warrant analysis of brains. In the present paper we compare carcass and brain residues of dieldrin in 23 herons of which both carcass and brain were analyzed.

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

    Although the multi-component weight loss supplement Redotex is banned in the United States, the supplement can be obtained in Mexico. The intent of this report was to describe the pattern of Redotex calls received by a statewide poison center system. Cases were all Redotex calls received by Texas poison centers during 2000-2008. The distribution of total calls and those involving ingestion of the supplement were determined for selected demographic and clinical factors. Of 34 total Redotex calls received, 55.9% came from the 14 Texas counties that border Mexico. Of the 22 reported Redotex ingestions, 77.3% of the patients were female and 45.5% 20 years or more. Of the 17 ingestions involving no co-ingestants, 52.9% were already at or en route to a health care facility, 41.2% were managed on site, and 5.9% was referred to a health care facility. The final medical outcome was no effect in 23.5% cases, minor effect in 5.9%, moderate effect in 11.8%, not followed but minimal clinical effects possible in 47.1%, and unable to follow but judged to be potentially toxic in 11.8%. Most Redotex calls to the Texas poison center system originated from counties bordering Mexico.

    In the course of their clinical work or during leisure activity, family physicians occasionally may encounter patients with injuries from marine creatures. Poisoning, envenomation, and direct trauma are all possible in the marine environment. Ciguatera poisoning can result from ingestion of predatory fish that have accumulated biotoxins. Symptoms can be gastrointestinal or neurologic, or mixed. Management is mostly symptomatic. Scombroid poisoning results from ingestion of fish in which histamine-like substances have developed because of improper refrigeration. Gastrointestinal and systemic symptoms occur. Treatment is based on antihistamines. Envenomations from jellyfish in U.S. waters and the Caribbean are painful but rarely deadly. Household vinegar deactivates the nematocysts, and manual removal of tentacles is important. Treatment is symptomatic. Heat immersion may help with the pain. Stingrays cause localized damage and a typically severe envenomation. The venom is deactivated by heat. The stingray spine, including the venom gland, typically is difficult to remove from the victim, and radiographs may be necessary to localize the spine or fragment. Surgical débridement occasionally is needed. Direct trauma can result from contact with marine creatures. Hemorrhage and tissue damage occasionally are severe. Infections with organisms unique to the marine environment are possible; antibiotic choices are based on location and type of injury. Shark attacks, although rare, require immediate attention.

    The development of recycling process of defective (U,Gd)O{sub 2} scrap is one of the important subject in this project. Among the several burnable absorbers, Gd has a very large neutron absorption cross-section. Therefore, gadolinia bearing UO{sub 2} fuel, (U,Gd)O{sub 2}, has been widely used as a burnable absorber in light water reactors. During the pellet fabrication process, fairly amount of defective (U,Gd)O{sub 2} pellets are produced and it is necessary to recycle the scraps. Generally, the defective scraps are powdered through the oxidation in air in the temperature range of 450 to 550 deg C and then mixed with co-milled powder, and further processed to fabricate (U,Gd)O{sub 2} pellets. In addition, the sintered pellet properties are closely depend on the powder property of oxidized M{sub 3}O{sub 8} powder. Therefore, the careful investigate of oxidation kinetics and related powder property of (U,Gd)O{sub 2} is very important. The oxidation behavior of UO{sub 2}-6wt% Gd{sub 2}O{sub 3} and UO{sub 2}-12wt% Gd{sub 2}O{sub 3} has been studied in the temperature range from 350 to 700 deg C using TGA and XRD techniques in air. UO{sub 2} was necessarily oxidized to U{sub 3}O{sub 8} regardless of oxidation temperature and its weight gain was 4wt%. However, (U,Gd)O{sub 2} exhibit a different oxidation behavior ; The final phase and saturated weight gain depends on oxidation temperature. The saturated weight gain increases with oxidation temperature up to 500deg C and thereafter decreases with temperature. In addition, the amount of weight gain obtained at 500 deg C was smaller in UO{sub 2}-12wt% Gd{sub 2}O{sub 3} than in UO{sub 2}-6wt% Gd{sub 2}O{sub 3} and the final phase at the saturated weight gain was M{sub 3}O{sub 8} in UO{sub 2}-6wt% Gd{sub 2}O{sub 3} but the mixture of M{sub 4}O{sub 9} and M{sub 3}O{sub 8} in UO{sub 2}-12wt% Gd{sub 2}O{sub 3}. It is supposed that Gd substitution for U decreases the equilibrium O/M ratio and thereby enhance the stability of M

    Highlights: • Comprehensive introduction and supplementary concepts as a review paper. • Developing an integrated long-term fuel management strategy for a SMR. • High reliable 3-D core modeling over fuel pins against the traditional LRM. • Verifying the expert rules of large PWRs for an advanced small PWR. • Investigating large numbers of safety parameters coherently. - Abstract: In this paper, long-term fuel management (FM) strategies are introduced and analyzed for a new advanced Pressurized Light Water Reactor (PWR) type of Small Modular Reactors (SMRs). The FM strategies are developed to be safe and practical for implementation as much as possible. Safety performances, economy of fuel, and Quality Assurance (QA) of periodic equilibrium conditions are chosen as the main goals. Flattening power density distribution over fuel pins is the major method to ensure safety performance; also maximum energy output or permissible discharging burn up indicates economy of fuel fabrication costs. Burn up effects from BOC to EOC have been traced, studied, and highly visualized in both of transport lattice cell calculations and diffusion core calculations. Long-term characteristics are searched to gain periodical equilibrium characteristics. They are fissile changes, neutron spectrum, refueling pattern, fuel cycle length, core excess reactivity, average, and maximum burn up of discharged fuels, radial Power Peaking Factors (PPF), total PPF, radial and axial power distributions, batch effects, and enrichment effects for fine regulations. Traditional linear reactivity model have been successfully simulated and adapted via fine core and burn up calculations. Effects of high burnable neutron poison and soluble boron are analyzed. Different numbers of batches via different refueling patterns have been studied and visualized. Expert rules for large type PWRs have been influenced and well tested throughout accurate equilibrium core calculations.

    Ciguatera, an ichtyosarcotoxism linked to the consumption of usually healthy coral fish is a common poisoning in the Pacific, Caribbean and Indian Ocean where it is endemic. However, increased tourism and commercial transportation of tropical fish for consumption make it an unexceptional intoxication in countries away from its endemic area. Environmental stresses such as climate changes also contribute to the expansion of its geographical area. The non-specific clinical symptomatology is characterized by the occurrence of gastrointestinal, cardiovascular, nervous and general signs few hours after eating a ciguatoxic fish. The diagnosis is clinical and relatively easy in endemic areas but much less for physicians who are rarely confronted with, which is a source of prolonged diagnostic delays and a significant increase in spending. Treatment of ciguatera is symptomatic but new treatments, still experimental, give a real hope for the future.

  1. Fatal aluminium phosphide poisoning

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

    Borron, Stephen W; Baud, Frederic J

    2012-08-01

    Cyanide poisoning can present in multiple ways, given its widespread industrial use, presence in combustion products, multiple physical forms, and chemical structures. The primary target of toxicity is mitochondrial cytochrome oxidase. The onset and severity of poisoning depend on the route, dose, physicochemical structure and other variables. Common poisoning features include dyspnea, altered respiratory patterns, abnormal vital signs, altered mental status, seizures, and lactic acidosis. Our present knowledge supports cyanide poisoning treatment based on excellent supportive care with adjunctive antidotal therapy. Multiple antidotes exist and vary in regional availability. All currently marketed antidotes appear to be effective. Antidotal mechanisms include chelation, formation of stable, less toxic complexes, methemoglobin induction, and sulfane sulfur supplementation for detoxification by endogenous rhodanese. Each antidote has advantages and disadvantages. For example, hydroxocobalamin is safer than the methemoglobin inducers in patients with smoke inhalation. Research for new, safer and more effective cyanide antidotes continues.

    Full Text Available BACKGROUND : Organophophorous poisoning constitutes one of the most frequent poisoning in clinical practice all over the country and especially in this area where agriculture is the chief economic occupation. Acute organophophorous poisoning ranks foremost in the list of agents which causes acute pesticide poisoning in the developing countries. Acute poisoning, accidental or due to deliberate ingestion or inhalation of these organophosphate chemicals is an important and one of the most common medical emergencies. Hence the present stud y is undertaken to assess severity of poisoning, management and outcome of organophosphorous poisoning cases admitted in Government General Hospital, Kakinada, A. P. AIMS/OBJECTIVES: 1. Assessment of severity of Organophosphorous poisoning according to Dri esbach’s criteria 2. To study the morbidity and mortality in these patients. MATERIALS AND METHOD S: In this descriptive study fifty patients with organophosphorous insecticide poisoning were evaluated by clinical examination. They were investigated, treate d and their treatment outcome were analyzed. RESULTS: 1. Chlorpyriphos and monocrotophos(together 66% were the most commonly used pesticides. 2. 82% cases reached the hospital within 6 hours for commencement of treatment and were mostly of moderate to se vere degree of OP poisoning while mild cases of accidental poisoning reached after 12 hours. Hence the mortality is high in the former group only. 3. When the severity of poisoning was graded by applying Dreisbach's criteria at the time of admission 34% ha d severe degree of poisoning, 26% had moderate poisoning while 40% of cases presented with mild degree of poisoning. (Most of the cases were accidental inhalation and skin contact exposure. 4.

    To determine the standing of mortality by poisoning in children in the Mexican Republic, in the years from 1979-1994. Secondary sources were employed. Analyzed variables were: age, sex, year, external cause of trauma and poisoning according to the 9th International Classification of Diseases: E850-E858, E860-E869 and E905. Tendencies by specific causes were analyzed with a Poisson regression model and relative risk by age, sex and district were obtained. A total of 11,272 children under 15 years of age were recorded. The main causes were poisoning and toxic reactions caused by venomous plants or animals (E905); accidental poisoning by household gas or carbon monoxide (E868); and accidental poisoning by other drugs (E858). The relative risk was highest in age group Aguascalientes consistently presented the highest risk values and the state of Nuevo Leon, the lowest. Poisoning is an important cause of child mortality. Considering that most of these deaths can potentially be prevented since they occur at home it is recommended that responsible adults can build protection into their environment and into the way society operates. Prevention should involve a multidisciplinary approach since the phenomenon has multiple causes and possible solutions.

  15. Pharmacokinetic Studies on Oximes in Organophosphate Poisoning: A Mini Review

    Directory of Open Access Journals (Sweden)

    Girish Thunga

    2014-09-01

    Full Text Available Organophosphate (OP poisoning is one of the most common causes of poisoning in developing countries especially in Southeastern Asia. Poisoning with phosphorus-containing organic chemicals or OP compounds can be managed with antidotes like oximes which are potential reactivators of acetylcholinesterase (AChE. The efficacy of oxime therapy in OP poisoned patients mainly depends upon various factors such as different dose plans, infusion rate of oximes, genetic differences of patients, type of oxime used and chemical nature of the OP compound ingested. Studies on pralidoxime kinetics in OP poisoned patients have shown that reactivation of AChE depends on the plasma concentration of oximes as well as OP compounds. The plasma concentration of oximes mainly depends on the dose plan from intermittent injection to continuous infusion after a loading dose. The incontrovertible fact is that the intermittent dosing of oximes results in deep troughs in blood pralidoxime/oxime levels (BPL whereas continuous infusion of oximes maintains steady state plasma concentrations. Many published literature also highlighted pralidoxime via continuous infusion results in better outcomes with minimum fluctuation in BPL compared to intermittent dosing. At therapeutic doses, adverse effects of oximes are reported to be minimal. But high BPL is associated with some common adverse effects including dizziness, blurred vision and diastolic hypertension. Considering all the facts, it is important to note that kinetic studies of oximes are useful not only in deciding the dose regimen, but also in predicting the possible side-effects.

    Full Text Available Organophosphate poisoning is an important medical emergency exist in agriculture-oriented countries such as India. This case report describes the treatment strategies followed for a management of suicidal intoxication of a pregnant woman by chlorpyrifos compound at a secondary care public hospital, Udhagamandalam, India. The patient was unable to perceive fetal movements and had classic clinical symptoms of organophosphate poisoning such as excess salivation and pinpoint pupil. The patient was administered with 2 g of pralidoxime and 10 ampoules of atropine sulfate (1.2 mg each. The fetotoxic evaluation showed fetal death. The antidote given to the patient was according to the criteria given by the World Health Organization. The late admission of the patient may be considered as a reason for fetal death. Psychosocial, educational programs are highly recommended for the population in this region to reduce the number of intentional poisoning attempts.

    Full Text Available Objective: The scale of the problem of poisoning is enormous hence clinico epidemiological spectrum of all poisoning cases need to explore to generate the management tool. Methods: This prospective study was done at two medicine units (Unit 5 and 10 of Dhaka Medical College Hospital from July to December 2010 where all poisoning cases were seen. A total of 2890 patients were admitted out of which 600 were taken into the study. Results: Among the poisoning cases 29% were pesticide, 27% travel related poisoning, and 20% benzodiazepine. 70% of poisoning occurred below 30 years of age and male: female ratio was 3:2. Incidence of poisoning was highest among students (31% and housewives (25%. Majority of the patients were from urban area (76% and most common intention was suicidal (66%. Familial disharmony was the prime cause (63% behind poisoning. 42% cases got admitted between 5-8 hours of poisoning and more than 80% patients were admitted in the hospital directly without getting any first aid anywhere. Sixty-eight percent had Glasgow coma scale (GCS score above 10 during admission. Cardinal clinical features of poisoning were nausea/vomiting (63%, drowsiness (56%, miosis (31%. Seventy percent patients were treated with only general and supportive treatment and specific antidotes were used in 30% cases. Case fatality for pesticide, benzodiazepine/anti-psychotic, rodenticide and snake bite was 6.9%, 2.2%, 8.3% and 3.3% respectively. Conclusion: To assess the magnitude of problem, awareness of the public for prevention, immediate first aid measures and quick hospital admission is crucial component of poisoning.

  19. Neurotoxic Shellfish Poisoning

    Directory of Open Access Journals (Sweden)

    Roberta Hammond

    2008-07-01

    Full Text Available Neurotoxic shellfish poisoning (NSP is caused by consumption of molluscan shellfish contaminated with brevetoxins primarily produced by the dinoflagellate, Karenia brevis. Blooms of K. brevis, called Florida red tide, occur frequently along the Gulf of Mexico. Many shellfish beds in the US (and other nations are routinely monitored for presence of K. brevis and other brevetoxin-producing organisms. As a result, few NSP cases are reported annually from the US. However, infrequent larger outbreaks do occur. Cases are usually associated with recreationally-harvested shellfish collected during or post red tide blooms. Brevetoxins are neurotoxins which activate voltage-sensitive sodium channels causing sodium influx and nerve membrane depolarization. No fatalities have been reported, but hospitalizations occur. NSP involves a cluster of gastrointestinal and neurological symptoms: nausea and vomiting, paresthesias of the mouth, lips and tongue as well as distal paresthesias, ataxia, slurred speech and dizziness. Neurological symptoms can progress to partial paralysis; respiratory distress has been recorded. Recent research has implicated new species of harmful algal bloom organisms which produce brevetoxins, identified additional marine species which accumulate brevetoxins, and has provided additional information on the toxicity and analysis of brevetoxins. A review of the known epidemiology and recommendations for improved NSP prevention are presented.

However, several other manifestations are described. We review the spectrum of symptoms and signs in OP poisoning as well as the different approaches to clinical features in these patients. Materials and Methods: Articles were obtained by electronic search of PubMed® between 1966 and April 2014 using the search terms organophosphorus compounds or phosphoric acid esters AND poison or poisoning AND manifestations. Results: Of the 5026 articles on OP poisoning, 2584 articles pertained to human poisoning; 452 articles focusing on clinical manifestations in human OP poisoning were retrieved for detailed evaluation. In addition to the traditional approach of symptoms and signs of OP poisoning as peripheral (muscarinic, nicotinic and central nervous system receptor stimulation, symptoms were alternatively approached using a time-based classification. In this, symptom onset was categorized as acute (within 24-h, delayed (24-h to 2-week or late (beyond 2-week. Although most symptoms occur with minutes or hours following acute exposure, delayed onset symptoms occurring after a period of minimal or mild symptoms, may impact treatment and timing of the discharge following acute exposure. Symptoms and signs were also viewed as an organ specific as cardiovascular, respiratory or neurological manifestations. An organ specific approach enables focused management of individual organ dysfunction that may vary with different OP compounds. Conclusions: Different approaches to the symptoms and signs in OP poisoning may better our understanding of the underlying mechanism that in turn may assist with the management of acutely poisoned patients.

    A medical visit for plant ingestion is rare in the pediatric emergency services but may involve a high toxicity. The botanical toxicology training of health staff is often very limited, and it can be difficult to make a diagnosis or decide on the appropriate treatment. To study the epidemiological and clinical characteristics of poisoning due to plant ingestion in order to increase the knowledge of the health professional. A descriptive retrospective study was conducted on patients seen in a pediatric emergency department after the ingestion of plant substances from January 2008 to December 2012. During the period of study, 18 patients had ingested possible toxic plants. In 14 cases, it was considered to be potentially toxic: broom, oleander, mistletoe, butcher's-broom, and vulgar bean (2), Jerusalem tomato, castor (2), Jimson weed, potus, marijuana, and mushrooms with digestive toxicity (2). Among the potentially toxic cases, the ingestion was accidental in 10 patients, 2 cases were classed as infantile mistreatment, 1 case had recreational intention, and another one suicidal intentions. The ingestion of oleander, castor and Jimson weed had major toxicity. The potential gravity of the ingestion of plant substances and the variety of the exposure mechanism requires the pediatrician to bear in mind this possibility, and to be prepared for its diagnosis and management. Specific preventive information measures need to be designed for the families and for the regulation of toxic plants in playgrounds. Copyright © 2014 Asociación Española de Pediatría.

    TOMÁŠ IFKA

    2012-03-01

    Full Text Available The influence of CaO and P2O5 upon the reactivity of cement raw meal was investigated in this paper. Ash of bone meal containing Ca3(PO42 - 3CaO·P2O5 was used as the source of P2O5. Two series of samples with different content of the ash of bone meal were prepared. In the first series, the ash of bone was added into cement raw meal. The second series of samples were prepared by considering ash as one of CaO sources. Therefore, the total content of CaO in cement raw meal was kept constant, while the amount of P2O5 increased. These different series of samples were investigated by analyzing free lime content in the clinkers. The XRD analysis and Electron Micro Probe Analyzer analysis of the clinkers were also carried out. Two parameters were used to characterize the reactivity of cement raw meal: content of free lime and Burnability Index (BI calculated from free lime content in both series of samples burnt at 1350 ºC, 1400 ºC, 1450 ºC and 1500 ºC. According to the first parameter, P2O5 content that drastically makes worse the reactivity of cement raw meal was found at 1.11 wt.% in the first series, while this limit has reached 1.52 wt.% in the second one. According to the BI, the limit of P2O5 was found at 1.42 wt. % in the first series and 1, 61 wt.% in the second one. Furthermore, EPMA has demonstrated the presence of P2O5 in both calcium silicate phases forming thus solid solutions.

    2015-06-01

    Until very recently, toxicity was not considered a trait observed in birds, but works published in the last two decades started to shed light on this subject. Poisonous birds are rare (or little studied), and comprise Pitohui and Ifrita birds from Papua New Guinea, the European quail, the Spoor-winged goose, the Hoopees, the North American Ruffed grouse, the Bronzewings, and the Red warbler. A hundred more species are considered unpalatable or malodorous to humans and other animals. The present review intends to present the current understanding of bird toxicity, possibly pointing to an ignored research field. Whenever possible, biochemical characteristics of these poisons and their effects on humans and other animals are discussed, along with historical aspects of poison discovery and evolutionary hypothesis regarding their function.

    Full Text Available Due to climate and socio-economic issues in Turkey, the incidence of carbon monoxide (CO poisoning is high, especially in winter. Clinical manifestations may vary depending on the type of CO source, concentration and duration of exposure. The symptoms of CO poisoning predominantly manifest in lots of organs and systems with high oxygen utilization, especially the brain and the heart. The primary aim in oxygen therapy is to eliminate CO and to reduce its toxic effects. In this context, normobaric and hyperbaric oxygen therapy are used to achieve these goals. Normobaric oxygen (NBO treatment is an easily accessible and relatively not expensive modality, where hyperbaric oxygen (HBO therapy requires specific equipment, certified staff and is available only in some centers. Additionally, HBO treatment has several additional advantages over NBO treatment. Despite its benefits, it is compulsory to search for some criteria in selecting patients to be treated because of the limited availability and access of hyperbaric facilities. For an effective evaluation and an optimal treatment, advanced education of the healthcare professionals on the use of oxygen delivery modalities in the management of CO poisoning is imperative. In this review, it has been aimed to outline the significance of oxygen treatment modalities and to determine patient selection criteria for HBO treatment in the management of CO poisoning which continues to be an important threat to community health care.

    Clinical features of mercury poisoning are nonspecific, and a detailed history is very valuable. The silvery, shiny appearance of mercury makes it very exciting and attractive for children. The overall half-life of elemental mercury in the body averages approximately 2 months. Chelation therapy with dimercaptosuccinic acid is the treatment of choice if the urine or blood level of mercury is high or the symptoms are profound. Here, we describe a 14-year-old boy with fever, respiratory distress, and body rash. Investigation leading to a diagnosis of mercury poisoning was made only after his mother presented with the similar symptoms a few days later.

    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.

  17. Cartap hydrochloride poisoning: A clinical experience

    Full Text Available Cartap hydrochloride, a nereistoxin analog, is a commonly used low toxicity insecticide. We describe a patient who presented to the emergency department with alleged history of ingestion of Cartap hydrochloride as an act of deliberate self-harm. The patient was managed conservatively. To our knowledge this is the first case report of Cartap hydrochloride suicidal poisoning. Cartap toxicity has been considered to be minimal, but a number of animal models have shown significant neuromuscular toxicity resulting in respiratory failure. It is hypothesized that the primary effect of Cartap hydrochloride is through inhibition of the [ 3 H]-ryanodine binding to the Ca 2+ release channel in the sarcoplasmic reticulum in a dose-dependent manner and promotion of extracellular Ca 2+ influx and induction of internal Ca 2+ release. This results in tonic diaphragmatic contraction rather than paralysis. This is the basis of the clinical presentation of acute Cartap poisoning as well as the treatment with chelators namely British Anti Lewisite and sodium dimercaptopropane sulfonate.

  19. Acute aluminium phosphide poisoning, what is new?

    Directory of Open Access Journals (Sweden)

    Yatendra Singh

    2014-01-01

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

    The Act on Nature Conservation of 16.04.2004 (Official Journal, 2004, No 92, item 880) imposes on private individuals the duty to register some animals. The data collected by Kraków municipal authorities and delivered to the Poison Information Centre (Colleglum Medicum, Jagiellonian University) indicate that there are following species in private hands in the city and its surroundings: 11 individuals of Naja naja, 2--Hydrodynates gigas and 55-- Dendrobates spp. According to these information the employees of the PIC elaborated the advice on the treatment of specific animals' poisoning. In the period May 2003 - May 2004 (before the above Act came into force) there were 143 individuals from Brachypelma genus and 3 scorpions (Pandinus imperator) registered in Krakow. These species produce venoms which take local effect. According to art. 64 (1) of the above Act it is compulsory to register amphibians, reptiles, birds and mammals. However, it would be desirable to introduce the duty to register also dangerous species of invertebrates and fishes. It would provide the complete list of poisonous animals kept in private hands. Thus, it would be possible to estimate any possible threats and to elaborate adequate treatment in case of specific animals' poisoning.

Because of the clustering of clinical poisoning by household units, investigation was focussed on potential sources common to all members of the households. After excluding water, olive oil and a variety of foodstuff, lead in high concentrations was discovered in locally ground flour in all affected households. The source of poisoning was lead poured into the fissures between the metal housing and the driveshaft of the millstone. Significant lead contamination of freshly ground flour was demonstrated in 23% of the 146 community flour mills operating in West Bank villages. Since the completion of these studies, similar outbreaks of lead poisoning caused by contaminated flourmills have been identified in the Upper Galilee and in Spain. As the methods of milling in the Mediterranean area are similar, a coordinated international effort is needed in order to eliminate this health hazard from countries where similar community stone mills are still in use.

    This review article is the third in a series on animal poisoning in Europe and represents a collation of published and non-published wildlife poisoning data from Belgium, France, Greece, Italy and Spain over the last 10 years. Birds, particularly waterfowl and raptors, were more commonly reported as victims of poisoning than wild mammals. In addition to specific but important toxicological disasters, deliberate primary or secondary poisonings are of concern to all countries. Metals (particularly lead arising from sporting/hunting activities) and pesticides (mainly anticholinesterases and anticoagulants) are frequent causes of poisoning, and often have fatal consequences. A more unified and consistent approach throughout European countries to improve the reporting and the analytical confirmation of wildlife poisoning would help to reduce the number of cases of malicious or negligent animal poisoning. 2009 Elsevier Ltd.

    2016-05-01

    Full Text Available BACKGROUND Acute poisoning with various substances is a common medical emergency everywhere. WHO estimates poisoning as one of the common causes of increased mortality and morbidity. Acute ingestion of poisonous substance is associated with high mortality unless an effective intervention is done. METHODS In this study, in an attempt to understand the profile of poisoning cases admitted in Kanyakumari Government Medical College, we have enrolled all the poisoning cases admitted in the Intensive Medical Care Unit in the time period of January 2015 to December 2015. It is a retrospective study and the data was collected from the medical records department. RESULTS A total of 502 cases were admitted of which 79.48% were males and 20.52% were females. Among them, 93.40% were due to intentional poisoning and 6.60% were due to accidental poisoning. The observed mortality rate was 14.34%. The poisoning cases clustered in the age group of 20–39 years, accounting to 57.17% of the total cases. Intentional poisoning was observed more in males in the age group of 20–29 years (81.32%. Organophosphorus compounds (28.68% followed by oleander seed (21.91%, followed by rat killer (Zinc phosphide (17.53%, Aluminium phosphide (7.57%, Tablet poisoning (5.78%, Pyrethroid (1.6%, carbamate (1% were the commonly used poison agents. CONCLUSION Pesticides are the most commonly used poisoning agents in rural India. Lack of knowledge and easy availability of such compounds make them a common source of poison. Incidence of poisoning is more among males compared to females because of increased occupational stress faced by them.

    Research designed to isolate and identify the bioactive compounds responsible for the toxicity of plants to livestock that graze them has been extremely successful. The knowledge gained has been used to design management techniques to prevent economic losses, predict potential outbreaks of poisoning, and treat affected animals. The availability of these compounds in pure form has now provided scientists with tools to develop animal models for human diseases, study modes of action at the molecular level, and apply such knowledge to the development of potential drug candidates for the treatment of a number of genetic and infectious conditions. These advances are illustrated by specific examples of biomedical applications of the toxins of Veratrum californicum (western false hellebore), Lupinus species (lupines), and Astragalus and Oxytropis species (locoweeds).

    Full Text Available Aim of the study: To present clinical and analytical aspects associated with sodium azide poisoning. The problems were verified on the basis of a case of sodium azide poisoning which was unique due to its circumstances and the development of an analytical method applied for medico-legal practice. Material and methods : The object of the study was a toxicological analysis of biological specimens collected from a woman who ingested two doses of sodium azide purchased over the Internet, in a suicide attempt. After the ingestion of the first dose, the clinical management in the form of symptomatic treatment indicated a possibility of recovery. However, the ingestion of a second dose of the xenobiotic, already in the hospital, caused death. Toxicological findings were obtained with the dedicated technique of gas chromatography-mass spectrometry (GC-EI-MS-MS after extraction combined with derivatization using pentafluorobenzyl bromide (PFBBr. Results : Post-mortem toxicological studies demonstrated sodium azide in the blood (0.18 mg/l and urine (6.50 mg/l samples collected from the woman. Conclusions : Cases of sodium azide poisoning are rare and difficult to treat, but a review of the literature over a longer interval of time shows that they continue to occur. Therefore, case studies of sodium azide poisoning, together with descriptions of research methodology, can be useful both in clinical terms and in the preparation of toxicological expert opinions for medico-legal purposes.

    Full Text Available Acute agrochemical poisoning is a leading cause of mortality and morbidity in India. Pendimethalin (herbicide and Pancycuron (fungicide are frequently used worldwide and considered quite a remarkably safe one for humans. Their acute toxicity is not yet widely known. Here we are reporting cases of their acute poisoning in young. To the best of our knowledge not a single such case of their poisoning has been reported so far in india. Such poisoning by entirely new compounds is an emerging problem in the tropics. In this communication we are reporting such unusual and entirely new toxicities and trying to highlight the need of their early recognition and timely management in rural regions where health facilities are already at the stake.

    It is likely that lead poisoning via drinking water is often overlooked because of its supposed rarity and nonspecific early symptoms, which result in delayed management. One case of severe lead poisoning via drinking water is reported. The diagnosis was long missed and a particularly long chelating treatment was required. The clinical features included lead colic, a Burton's lead line, anemia, polyneuritis and arterial hypertension. Eighteen courses of calcium EDTA were required to obtain 'biological recovery'. The poisoning was linked to a very long water supply lead pipe and potomania secondary to alcohol withdrawal. This case report illustrates how difficult the early recognition of lead poisoning can be, and underlines the need to inquire about a toxic aetiology, particularly via the environment, of otherwise unexplained pathological conditions.

    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.

    Organophosphate poisoning is a serious clinical entity and considerable morbidity and mortality. Several factors have been identified to predict outcomes of organophosphate poisoning. Organophosphates are lipophilic and therefore predicted to have a large volume of distribution and to rapidly distribute into tissue and fat. Thus, toxic effects of organophosphate would be expected to last longer in obese patients. We investigated the relationship between obesity and clinical course in 112 acute organophosphate-poisoned patients from an initial medical record review of 234 patients. One hundred twenty-two patients were excluded: 6 were children, 14 had an uncertain history of exposure and of uncertain agent, 10 were transferred to another hospital, 67 were discharged from the emergency department because their toxicity was mild, 21 had carbamate poisoning, and 4 did not have height or weight checked. Clinical features, body mass index, Glasgow Coma Scale, laboratory findings, serum cholinesterase activity, electrocardiogram finding, management, and outcomes were examined. The lipid solubility of the implicated organophosphate was characterized by its octanol/water coefficient. Forty of 112 patients were obese. Obese patients who were poisoned by high lipophilicity organophosphate compounds had a need for longer use of mechanical ventilation, intensive care unit care, and total length of admission. Body mass index can provide a guide to physicians in predicting clinical course and management in organophosphate-poisoned patients.

    Kerr, L A

    1990-10-01

    Insecticides, nitrates, gossypol, copper, and plants are a few of the common toxicoses observed in livestock in a particular specie due to various factors. Some species may have anatomical or physiological uniquenesses making them more susceptible to certain agents. Another specie may be exposed to some agents more frequently than others, increasing the likelihood of toxicosis in that specie. Once recognized, therapy is often unrewarding due to the advanced stage of the condition when first recognized, the stress involved in administering the treatment, and the unfeasibility of multiple treatments on many animals. Because of the poor response to treatment and the large number of animals potentially at risk, prevention assumes a greater importance in food animals than in companion animals. Prevention consists of making the diagnosis, findings and removing the source of the toxicant, and educating the owner on how future problems can be avoided.

    Thermal management is critical to space exploration efforts. In particular, efficient transfer and control of heat flow is essential when operating high energy sources such as nuclear reactors. Thermal energy must be transferred to various energy conversion devices, and to radiators for safe and efficient rejection of excess thermal energy. Applications for space power demand exceptionally long periods of time with equipment that is accessible for limited maintenance only. Equally critical is the hostile and alien environment which includes high radiation from the reactor and from space (galactic) radiation. In space or lunar applications high vacuum is an issue, while in Martian operations the systems will encounter a CO2 atmosphere. The effect of contact at high temperature with local soil (regolith) in surface operations on the moon or other terrestrial bodies (Mars, asteroids) must be considered.

    2015-01-01

    Full Text Available Paraquat (1, 1′-dimethyl-4, 4′-dipyridylium is a bipyridilium herbicide used widely in our country and is a highly toxic compound. This compound is very notorious to cause rapid development of renal, liver, and respiratory failure with very high mortality due to lack of specific antidote and dearth of high-quality evidence-based treatment. Respiratory system involvement is the most common cause of death in these people. We hereby report a fatal case of a 30-year-old male with a history of paraquat consumption. The patient developed oliguric renal failure, deterioration of liver function, and acute respiratory distress syndrome over next few days. Different treatment modalities were tried to manage patient′s condition. In this case, none of the strategies worked well, and death ensued due to multi-organ dysfunction syndrome.

    2015-02-01

    Organophosphates (OPs) and carbamates have a wide variety of applications, most commonly as pesticides used to eradicate agricultural pests or control populations of disease-carrying vectors. Some OP and carbamates have therapeutic indications such as physostigmine. Certain organophosphorus compounds, known as nerve agents, have been employed in chemical warfare and terrorism incidents. Both classes inhibit acetylcholinesterase (AChE) enzymes, leading to excess acetylcholine accumulation at nerve terminals. In the setting of toxicity from either agent class, clinical syndromes result from excessive nicotinic and muscarinic neurostimulation. The toxic effects from OPs and carbamates differ with respect to reversibility, subacute, and chronic effects. Decontamination, meticulous supportive care, aggressive antimuscarinic therapy, seizure control, and administration of oximes are cornerstones of management. Copyright © 2015 Elsevier Inc.

    2014-11-01

    Full Text Available BACKGROUND AND OBJECTIVES: Organophosphorus compound poisoning is the most common medico toxic emergency in India the increase in pesticide use in agriculture has paralleled the increase in the use of these products for deliberate self-warm. Respiratory failure is the most common complication of OP poisoning leading to death. Early recognition and prompt ventilator support may improve survival. Owing to limited availability of resources, all OP poisoning patients are not managed in ICUs in Indian setup. It is therefore important that clinical features and criteria to predict the need for ventilator support be identified at initial examination. Hence this study was undertaken to assess the severity of organophosphorus compound poisoning both clinically by using Peradeniya scoring and by estimating serum choline esterase levels. METHODS: Cross sectional study was done at basaveswar teaching and general hospital attached to MR Medical College. Cases with history of exposure to organophosphorus compound within previous 24 hours were chosen after applying inclusion and exclusion criteria. Patients were evaluated for Peradeniya OP poisoning scale and serum cholinesterase levels for assessment of severity of poisoning. Serum cholinesterase levels and Peradeniya OP poisoning scale were studied to predict the need for ventilator support. The results were analyzed using Chi-square test. STATISTICAL ANALYSIS: It was done using pearson’s chi square test. RESULTS: In this study requirement of ventilator support was seen in 36% of patients. Mortality in our study was 18%. Only 15.6% of patients with mild grade of poisoning according to Peradeniya OP poisoning scale required ventilator support, whereas 84.4% did not require ventilator support. Most of patients with moderate (70.6% and severe poisoning (100% according to Peradeniya OP poisoning scale required ventilator support. 93.7% of patients with serum cholinesterase levels more than 50% did not require

    Full Text Available Many cases of carbon monoxide poisoning in Taiwan are due to burning charcoal. Nevertheless, few reports have analyzed the mortality rate of these patients who survive to reach a hospital and die despite intensive treatment. Therefore, this study examined the clinical features, physiological markers, and outcomes after carbon monoxide poisoning and the associations between these findings.We analyzed the records of 261 patients who were referred for management of carbon monoxide intoxication between 2000 and 2010. Patients were grouped according to status at discharge as alive (survivor, n = 242 or dead (non-survivor, n = 19. Demographic, clinical, laboratory, and mortality data were obtained for analysis.Approximately half of the cases (49.4% attempted suicide by burning charcoal. Most of the patients were middle-aged adults (33±19 years, and were referred to our hospital in a relatively short period of time (6±10 hours. Carbon monoxide produced many serious complications after exposure: fever (26.1%, hypothermia (9.6%, respiratory failure (34.1%, shock (8.4%, myocardial infarction (8.0%, gastrointestinal upset (34.9%, hepatitis (18.4%, renal failure (25.3%, coma (18.0% and rhabdomyolysis (21.8%. Furthermore, the non-survivors suffered greater incidences of hypothermia (P<0.001, respiratory failure (P<0.001, shock (P<0.001, hepatitis ((P=0.016, renal failure (P=0.003, coma (P<0.001 than survivors. All patients were treated with high concentration of oxygen therapy using non-rebreather mask. However, hyperbaric oxygen therapy was only used in 18.8% of the patients. In a multivariate-Cox-regression model, it was revealed that shock status was a significant predictor for mortality after carbon monoxide poisoning (OR 8.696, 95% CI 2.053-37.370, P=0.003. Finally, Kaplan-Meier analysis confirmed that patients with shock suffered greater cumulative mortality than without shock (Log-rank test, Chi-square 147.404, P<0.001.The mortality rate for

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

    Deaths from drug overdose have become the leading cause of injury death in the United States, where the poison center system is available to provide real-time advice and collect data about a variety of poisonings. In 2012, emergency medical providers were confronted with new poisonings, such as bath salts (substituted cathinones) and Spice (synthetic cannabinoid drugs), as well as continued trends in established poisonings such as from prescription opioids. This article addresses current trends in opioid poisonings; new substances implicated in poisoning cases, including unit-dose laundry detergents, bath salts, Spice, and energy drinks; and the role of poison centers in public health emergencies such as the Fukushima radiation incident.

  16. Efficacy of pralidoxime in organophosphorus poisoning: Revisiting the controversy in Indian setting

    Directory of Open Access Journals (Sweden)

    I Banerjee

    2014-01-01

    Full Text Available Context: Poisoning with organophosphorus (OP compounds constitutes a global public health problem. Standard treatment of OP poisoning involves use of atropine and pralidoxime. While efficacy of atropine is well-established, clinical experience with pralidoxime in management of OP poisoning is controversial. Aims: To explore the efficacy of add-on pralidoxime with atropine over atropine alone in the management of OP poisoning. Settings and Design: An open-label, parallel-group, randomized clinical trial was conducted in a tertiary care district hospital in West Bengal. Materials and Methods: Patients presenting with features of OP poisoning were randomly allocated to receive atropine or atropine-plus-pralidoxime. Efficacy was assessed by analyzing mortality, requirement for ventilator support and the duration of stay in hospital. Statistical analysis: Chi-square test was done to compare the efficacy parameters between the two groups. A two-tailed P-value <0.05 was considered as statistically significant. Results: During the study period, 150 patients were screened following which 120 patients were randomized to either of the treatment arms. Add-on pralidoxime therapy did not offer any appreciable benefit over atropine alone in terms of reducing mortality (18.33% (11/60 versus 13.33% (8/60 and ventilator requirement (5% (3/60 versus 8.33% (5/60. However, patients randomized in the add-on pralidoxime arm experienced longer duration of hospital stay (7.02 ± 1.12 days than those receiving atropine-alone therapy (5.68 ± 1.87 days (P < 0.001. Conclusion: The present study suggested that add-on pralidoxime with atropine therapy did not offer any appreciable benefit over atropine alone in management of OP poisoning. However, further trials are needed to explore different dosing regimens of pralidoxime in order to determine its efficacy in OP poisoning.

    No therapy has been proved to be effective for patients with severe chloroquine poisoning, which is usually fatal. In a retrospective study of 51 cases, we found that ingestion of more than 5 g of chloroquine was an accurate predictor of a fatal outcome, and therefore chose this dose as the criterion for severe chloroquine poisoning. We selected as a control group 11 consecutive patients who had ingested more than 5 g of chloroquine between July 1983 and December 1985. We then undertook a prospective study to determine whether a better outcome could be obtained with immediate mechanical ventilation and the administration of diazepam and epinephrine. Eleven consecutive patients who ingested more than 5 g of chloroquine in 1986 received this combination therapy. Ten of these patients survived, whereas only one control had survived (P = 0.0003). There was no significant difference between the combination-therapy and control groups in age (29 +/- 3 vs. 27 +/- 2 years), amount of chloroquine ingested (7.5 +/- 0.5 vs. 8.5 +/- 0.8 g), systolic arterial pressure (74 +/- 2 vs. 74 +/- 3 mm Hg), or QRS duration (0.14 +/- 0.01 vs. 0.14 +/- 0.01 second). In our combination-therapy group, blood chloroquine levels ranged from 40 to 80 mumol per liter, whereas a literature search showed that no patient in whom blood levels were more than 25 mumol per liter had survived. These preliminary data suggest that combining early mechanical ventilation with the administration of diazepam and epinephrine may be effective in the treatment of severe chloroquine poisoning.

    Cortina, Tatiana Judith; Ferrero, Hilario Andrés

    2013-01-01

    Hydrofluoric acid is a highly dangerous substance with industrial and domestically appliances. Clinical manifestations of poisoning depend on exposure mechanism, acid concentration and exposed tissue penetrability. Gastrointestinal tract symptoms do not correlate with injury severity. Patients with history of hydrofluoric acid ingestion should undergo an endoscopy of the upper gastrointestinal tract. Intoxication requires immediate intervention because systemic toxicity can take place. We present a 5 year old girl who accidentally swallowed 5 ml of 20% hydrofluoric acid. We performed gastrointestinal tract endoscopy post ingestion, which revealed erythematous esophagus and stomach with erosive lesions. Two months later, same study was performed and revealed esophagus and stomach normal mucous membrane.

    Indigo, also known in Morocco as Nila, is a dye widely used in the coloring of Moroccan handicrafts. It is obtained from fermentation reactions on the leaves and branches of true indigo, Indigofera tinctoria, which is a widespread plant in tropical Africa and Asia. We report a case of fatal poisoning in a 3-year-old child after administration of indigo for therapeutic purposes. Death resulted from multiple organ failure. The toxicity of this compound is little known in the literature and deserves to be explored through toxicokinetic and toxicodynamic studies, in order to better determine the toxic constituents of the dye.

    2012-01-01

    Full Text Available Haloperidol, a butyrophenone neuroleptic drug, is an antipsychotic used in the treatment of adult schizophrenia and mania. It is used in children with neurological disorders like chorea and developmental disorders such as hyperactivity. With the advent of newer selective neuroleptics use of haloperidol is now on decline. However, in adults it is still the preferred drug especially in resource challenged settings. Extrapyramidal reactions occur frequently with haloperidol predominantly as parkinsonian symptoms. There are few case reports of accidental haloperidol poisoning in children and this one of them.

    Assessment of quality indicators allows clinicians to evaluate clinical assistance with a standard, to detect deficiencies and to improve medical assistance. Patients who came to emergency services of a tertiary level hospital for suspicion of poisoning from January 2011 to June 2012 were assessed using 20 quality indicators of pediatric poisoning. Data collection was performed by retrospective review of clinical reports. A total of 393 patients were admitted for suspicion of poisoning (0.3% of all admissions).The standard was reached in 11 indicators and not reached in 6: administration of activated charcoal within 2hours of poison ingestion (standard=90%, result=83.5%); attention within the first 15minutes of arriving in the emergency service (standard=90%, result=60.4%); start of gastrointestinal decontamination within 20minutes of arrival in emergency services (standard=90%, result=29.7%); performing of electrocardiogram on the patients poisoned with cardiotoxic substances (standard=95%, result=87%); judicial communication of cases of poisoning that could conceal a crime (standard=95%, result=31.3%), and collection of the minimal set of information of poisoned patients (standard=90%, result=1.9%). Three indicators could not be evaluated as a consequence of the limited number of cases where they could be applied (<5). The main deficiencies are related to delay in assistance, collection of information and completion of judicial reports. Giving these patients priority, designing a checklist to collect the main points of their management, and creating obligatory fields for data in computerized medical records, are the main actions available to achieve pediatric poisoning quality indicators in this emergency service.

    2015-03-01

    Full Text Available Background:Poisoning with ethylene glycol (EG can be fatal even if appropriate treatments are delivered. EG poisoning usually causes central nervous system depression, cardiovascular dysfunction, metabolic acidosis and acute renal failure (ARF. Case Report:A 33-year-old man was referred to the emergency department with reduced consciousness and dyspnea of four-hour duration due to unknown reason. The patient had no history of diabetes, hypertension, cardiac disease or asthma. He was tachycardic, tachypneic and hypertensive. Laboratory investigations revealed hyperglycemia, high serum creatinine, hyponatremia, hyperkalemia, leukocytosis and high anion gap metabolic acidosis (HAGMA. He was initially managed as diabetic ketoacidosis (DKA. Alternative diagnoses of toxic alcohols poisoning was considered as there was no improvement. EG ingestion was confirmed when the relatives found an empty bottle of automotive brake oil, a poly glycol-based product, in the patient’s room. Although he was treated with ethanol and hemodialysis, renal failure worsened and finally he succumbed to death due to severe sepsis on the seventh day of EG ingestion. Discussion: This case illustrates the difficulties posed by high toxicity as well as unraveled and delayed diagnosis of EG poisoning. High anion gap and high osmolal gap are characteristics of EG poisoning. Transient pancreatitis caused by EG and insulin resistance due to ARF are the possible explanations for hyperglycemia secondary to EG poisoning. Conclusion:EG poisoning may manifest with hyperglycemia and HAGMA resembling DKA. It is important for the clinician to have high degree of suspicion for EG poisoning in case of HAGMA and ARF refractory to common treatments.

    This retrospective study evaluated the frequency, etiology, therapy and prognosis of animal poisoning registered from 2003 to 2012. The relevant cases reported to the Swiss Toxicological Information Center (STIC) were compared with those from previously examined periods. Human medicines not approved for animals and pesticides represented the most common causes of poisoning in dogs. Novel cases occurred as a consequence of the exposure of dogs to ricinus fertilizers, grape residues from wineries, pepper lachrymatory spray and dry bouillon. Cats are still freequently poisoned by pyrethroid drugs that should be administered only to dogs. Agrochmical products are the main source of toxicities in farm animals. Most poisonings in horses and exotic animals took place due to toxic plants. In addition, two tigers died of a secondary poisoning after ingestion of meat from euthanized calves.

    The majority of the literature on poisonous plant species in China is published in Chinese and not available to the majority of interested researchers and grassland managers in other countries. Therefore, a review of the Chinese literature was conducted to summarize the occurrence of poisonous plant species on temperate grasslands in China. We reviewed the literature to obtain general information on poisonous species but focus on locoweeds (Astragalus and Oxytropis spp.), drunken horse grass [Achnatherum inebrians (Hance) Keng ex Tzvelev] and langdu (Stellera chamaejasme L.) for information on their toxins, distribution and ecology, control methods and alternate uses. Of the almost 1300 poisonous species found on grasslands in China, these species are responsible for an estimated 80% of all livestock losses. This includes loss of performance as well as mortality. The locoweeds are a complex made up of Oxytropis and Astragalus species. The toxic principle in this complex, as well as in drunken horse grass, is the result of an endophyte fungus whereas in langdu it is produced by the plant. All these species are native to the grasslands, which suggest they have been a problem ever since herding began. Over that period of at least several millennia, herders would have learned and adapted to the presence of poisonous species. Strategies were developed and therapies employed to allow the animals to cope before and after poisoning. Nevertheless, grazing management could still be refined that would allow the use of the toxic legumes, while preventing poisonous symptoms, as has been tested elsewhere.

    Travel-related poisoning is an emerging social and public health emergency in Bangladesh but its cause and significance have not been determined. To investigate this syndrome we performed a prospective clinical study and retrospective analysis of hospital records in a general medicine unit of a public tertiary care teaching hospital in Dhaka, Bangladesh, using toxicological analysis by fluorescence polarization immunoassay (FPIA) and liquid chromatography coupled to time-of-flight mass spectrometry (LC-TOF MS). The participants of the prospective study were 130 consecutive patients aged 16-80 years who were admitted with central nervous system depression (Glasgow Coma Score 3-14) after using public transportation, in the absence of other abnormalities, from January through June 2004, and a convenience sample of 15 such patients admitted during 3 days in May 2006. In 2004-2006, travel-related poisoning increased from 6.1 to 9.5% of all admissions (210-309 of 3266-3843 per year), representing 46.6-55.7% of all admitted poisoning cases. Incidents were associated with bus (76%), taxi, train, and air travel, or local markets; 98% of patients remembered buying or accepting food or drinks before losing consciousness. Direct financial damage (missing property) was diverse and frequently existential. Among 94 urine samples analyzed by FPIA, 74% tested positive for benzodiazepines. Among 15 urine samples analyzed by LC-TOF MS, lorazepam was detected in all; five also contained diazepam or metabolites; nitrazepam was present in three. FPIA results obtained for these 15 samples were below the recommended cut-off in eight (53%; lorazepam only). Our findings show that the massive medicosocial emergency of travel-related poisoning in Bangladesh is the result of drug-facilitated organized crime and that benzodiazepine drugs are used to commit these crimes, suggesting modifications to the local emergency management of the victims of this type of poisoning. They also highlight the

    Beyer, W.N.; Spann, J.W.; Sileo, L.; Franson, J.C.

    1988-01-01

    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-owls 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-aminoievulinic 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 III ppm in female northern bobwhites. Median renal Pb concentrations varied from 22 ppm in red-winged 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

    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.

  2. Chronic lead poisoning in horses

    Energy Technology Data Exchange (ETDEWEB)

    Knight, H.D.; Burau, R.G.

    1973-05-01

    Chronic lead poisoning in horses was manifested as anorexia, loss of body weight, muscular weakness, anemia, laryngeal hemiplegia, and, terminally, inhalation pneumonia. Some deaths were sudden and unexplained. The lead content in liver specimens from 10 horses was greater than that considered indicative of lead intoxication; however, the lead content of blood was equivocal. The most conclusive laboratory finding was increased urine lead concentration after chelation therapy. The concentration of lead in a sample of vegetation considered to be representative of what a horse would eat if he was grazing in the area sampled was 325 ppM (oven-dry basis). It was determined that a 450-kg horse grazing grass of this lead content would consume 2.9 Gm of lead daily (6.4 mg/kg of body weight), an amount considered toxic for horses. Leaching lowered the calcium content of the forage but failed to reduce the lead concentration of the plants significantly, thus opening the possibility that winter rains might have influenced the onset of poisoning. Airborne fallout from a nearby lead smelter was proposed as the primary mode of pasture contamination.

  3. Arsenic – Poison or medicine?

    Directory of Open Access Journals (Sweden)

    Karolina Kulik-Kupka

    2016-04-01

    Full Text Available Arsenic (As is commonly known as a poison. Only a few people know that As has also been widely used in medicine. In the past years As and its compounds were used as a medicine for the treatment of such diseases as diabetes, psoriasis, syphilis, skin ulcers and joint diseases. Nowadays As is also used especially in the treatment of patients with acute promyelocytic leukemia. The International Agency for Research on Cancer (IARC has recognized arsenic as an element with carcinogenic effect evidenced by epidemiological studies, but as previously mentioned it is also used in the treatment of neoplastic diseases. This underlines the specificity of the arsenic effects. Arsenic occurs widely in the natural environment, for example, it is present in soil and water, which contributes to its migration to food products. Long exposure to this element may lead to liver damages and also to changes in myocardium. Bearing in mind that such serious health problems can occur, monitoring of the As presence in the environmental media plays a very important role. In addition, the occupational risk of As exposure in the workplace should be identified and checked. Also the standards for As presence in food should be established. This paper presents a review of the 2015 publications based on the Medical database like PubMed and Polish Medical Bibliography. It includes the most important information about arsenic in both forms, poison and medicine. Med Pr 2016;67(1:89–96

  4. Congenital abnormalities in methylmercury poisoning

    1975-04-01

    This study was undertaken to determine the teratogenic potential of methylmercury on chick embryogenesis. Methylmercuric chloride was dissolved in sodium bicarbonate (0.2%) and administered to the chick embryos at doses ranging from 0.0009 to 0.010 mg per egg. The injections were made at days 2 and 3 on incubation (Groups A and B). All the embryos including controls were examined on the 7th day of incubation. Methylmercury poisoning was observed to be both embryolethal and teratogenic. Within the two groups, embryolethality was higher in Group A. The following congenital abnormalities were observed: exencephaly, shortened and twisted limbs, microphthalmia, shortened and twisted neck, beak abnormalities, everted viscera, reduced body size and hemorrhage all over the body. Exencephaly and limb abnormalities were very common. No differences in the incidence and types of gross abnormalities within both the groups (A and B) were noted. The incidence of malformations among the controls was low. The results of present investigation show that methylmercury poisoning is both embryolethal and teratogenic to early chick embryogenesis.

    Limited information exists about epidemiology and management of mushroom poisoning. We analyzed and described epidemiology, clinical presentation, and clinical course of mushroom-poisoned patients admitted to emergency departments (EDs) of the Province of Parma, Italy. Data from the database of mycological service were matched with clinical information retrieved from hospitals' database, from January 1, 1996 to December 31, 2016. Mycologist consultation was obtained in 379/443 identified mushroom poisonings. A remarkable seasonality was found, with significant peak in autumn. Thanks to the collaboration, the implicated species could be identified in 397 cases (89.6%); 108 cases (24.4%) were due to edible mushrooms, Boletus edulis being the most represented (63 cases). Overall, 408 (92%) cases presented with gastrointestinal toxicity. Twenty cases of amatoxin poisoning were recorded (11 Amanita phalloides and 9 Lepiota brunneoincarnata). One liver transplantation was needed. We observed 13 cases of cholinergic toxicity and 2 cases of hallucinogenic toxicity. Finally, 46 cases were due to "mixed" toxicities, and a total of 69 needed hospitalization. Early identification and management of potentially life-threatening cases is challenging in the ED, so that a mycologist service on call is highly advisable, especially during periods characterized by the highest incidence of poisoning.

    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

    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.

    Mercury exists as organic inorganic and elementary forms in nature and is one of the most toxic metals that are poisonous for human beings. Mercury is commonly used in many different sectors of industry such as in insects formulas, agriculture products, lamps, batteries, paper, dyes, electrical/electronic devices, jewelry, and in dentistry. In this study, two siblings (one a 7-year-old boy and the other a 13 years old girl) are reported who developed chronic mercury poisoning as a result of long-term contact with batteries. Our aim is to emphasize the importance of mercury poisoning that is extremely rarely seen in childhood.

    Allergic contact dermatitis caused by the Toxicodendron (formerly Rhus) species-poison ivy, poison oak, and poison sumac-affects millions of North Americans every year. In certain outdoor occupations, for example, agriculture and forestry, as well as among many outdoor enthusiasts, Toxicodendron dermatitis presents a significant hazard. This review considers the epidemiology, identification, immunochemistry, pathophysiology, clinical features, treatment, and prevention of this common dermatologic problem. Recent research in prevention is emphasized, and resources to help in the identification of plants are provided in the bibliography. The literature was searched using a MEDLINE query for "Toxicodendron dermatitis", and the identified article bibliographies were searched as well.

    Full Text Available Lead is a relatively ubiquitous heavy metal with particular features such as resistance to corrosion, high malleability and wide variety of industrial applications. In medicine, however, it is considered as a slow-acting toxic substance affecting multiple body systems, specifically functioning as a potent neurotoxin in the central nervous system. Lead poisoning may be acute or chronic and can be due to occupational or environmental exposures. The history of lead poisoning dates back to ancient times. The present paper briefly describes the worldwide historical accounts of lead poisoning with a special focus on Iran.

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

  1. Potassium Permanganate Poisoning: A Nonfatal Outcome

    Full Text Available Acute poisoning by potassium permanganate is a rare condition with high morbidity and mortality. Diagnosis of the condition relies on a history of exposure or ingestion and a high degree of clinical suspicion. Oxygen desaturation and the presence of methemoglobin are also helpful indicators. Since no specific antidote is available, treatment is mainly supportive. Few cases have been reported in the literature following potassium permanganate ingestion, whether intentional or accidental, and most of the patients in these cases had unfavorable outcomes, which was not the case in our patient. Our patient, a 73-year-old male, purchased potassium permanganate over the counter mistaking it for magnesium salt, which he frequently used as a laxative. Several hours after he ingested it, he was admitted to the endocrine department at King Hussein Medical Center, Jordan, with acute rapidly evolving shortness of breath. During hospitalization, his liver function tests deteriorated. Since he was diagnosed early and managed promptly he had a favorable outcome.

  2. Organophosphorus and carbamate insecticide poisoning.

    Science.gov (United States)

    Vale, Allister; Lotti, Marcello

    2015-01-01

    Both organophosphorus (OP) and carbamate insecticides inhibit acetylcholinesterase (AChE), which results in accumulation of acetylcholine (ACh) at autonomic and some central synapses and at autonomic postganglionic and neuromuscular junctions. As a consequence, ACh binds to, and stimulates, muscarinic and nicotinic receptors, thereby producing characteristic features. With OP insecticides (but not carbamates), "aging" may also occur by partial dealkylation of the serine group at the active site of AChE; recovery of AChE activity requires synthesis of new enzyme in the liver. Relapse after apparent resolution of cholinergic symptoms has been reported with OP insecticides and is termed the intermediate syndrome. This involves the onset of muscle paralysis affecting particularly upper-limb muscles, neck flexors, and cranial nerves some 24-96 hours after OP exposure and is often associated with the development of respiratory failure. OP-induced delayed neuropathy results from phosphorylation and subsequent aging of at least 70% of neuropathy target esterase. Cramping muscle pain in the lower limbs, distal numbness, and paresthesiae are followed by progressive weakness, depression of deep tendon reflexes in the lower limbs and, in severe cases, in the upper limbs. The therapeutic combination of oxime, atropine, and diazepam is well established experimentally in the treatment of OP pesticide poisoning. However, there has been controversy as to whether oximes improve morbidity and mortality in human poisoning. The explanation may be that the solvents in many formulations are primarily responsible for the high morbidity and mortality; oximes would not be expected to reduce toxicity in these circumstances. even if given in appropriate dose. © 2015 Elsevier B.V.

  3. Pesticide Poisoning of Honeybees: A Review of Symptoms, Incident Classification, and Causes of Poisoning

    Directory of Open Access Journals (Sweden)

    Kiljanek Tomasz

    2016-12-01

    Full Text Available During the 2000s, the problem of pesticide poisoning of honeybees seemed to be almost solved. The number of cases has decreased in comparison to the 1970s. The problem of acute honeybee poisoning, however, has not disappeared, but instead has transformed into a problem of poisoning from ‘traditional’ pesticides like organophosphorus pesticides or pyrethroids, to poisoning from additional sources of ‘modern’ systemic neonicotinoids and fipronil. In this article, the biological activity of pesticides was reviewed. The poisoning symptoms, incident definitions, and monitoring systems, as well as the interpretation of the analytical results, were also reviewed. The range of pesticides, and the detected concentrations of pesticides in poisoned honeybee samples, were reviewed. And, for the first time, cases of poisoning related to neonicotinoids were reviewed. The latter especially is of practical importance and could be helpful to analysts and investigators of honeybee poisoning incidents. It is assumed that secondary poisoning induced by plant collected materials contaminated with systemic pesticides occurs. Food stored in a hive and contaminated with systemic pesticides consumed continuously by the same generation of winter bees, may result in sub-lethal intoxication. This leads to abnormal behaviour identified during acute intoxication. The final result is that the bees discontinue their social role in the honeybee colony super organism, and colony collapse disorder (CCD takes place. The process described above refers primarily to robust and strong colonies that were able to collect plenty of food due to effective plant protection.

    A procedure is described for the analysis of urushiol content of pharmaceutical preparations containing extracts of poison ivy (Toxicodendron radicans) and poison oak (T. diversilobum) in vegetable oils. The procedure involves extraction of the urushiols from the oily solutions using 90% methanol in water followed by GLC analysis of the extracts. Recoveries of both poison ivy and poison oak urushiols from solutions in corn oil, olive oil, sesame seed oil, and cottonseed oil were calculated. Correlation coefficients (r2) ranged from 0.97 to 1.00, and the coefficients of variations ranged from 3.08 to 7.90%.

    Purpose : To evaluate whether the early pulmonary irradiation can prevent or decrease the pulmonary damage and contribute to improve ultimate survival in paraquat lung. Materials and Methods : From Jun. 1987 to Aug. 1993, thirty patients with paraquat poisoning were evaluated. Fourteen of these patients were received pulmonary irradiation(RT). All of the patients ere managed with aggressive supportive treatment such as gastric lavage, forced diuresis, antioxidant agents and antifibrosis agents. Ingested amounts of paraquat were estimated into three groups(A: minimal < about 5cc, B: mouthful 5-50 cc, C: Large > 50cc). Pulmonary irradiation was started within 24 hours after admission(from day 1 to day 11 after ingestion of paraquat). Both whole lungs were irradiated with AP/PA parallel opposing fields using C0-60 teletherapy machine. A total of 10Gy(2Gy/fr. X 5 days)was delivered without correction of lung density. Results : In group A, all patients were alive regardless of pulmonary irradiation and in group C, all of the patients were died due o multi-organ failure, especially pulmonary fibrosis regardless of pulmonary irradiation. However, in group B, six of 7 patients(86%) with no RT were died due to respiratory failure, but 4 of 8 patients with RT were alive and 4 of 5 patients who received pulmonary irradiation within 4 days after ingestion of paraquat were all alive though radiological pulmonary fibrosis. All 3 patients who were received pulmonary irradiation after 4 days after ingestion were died due to pulmonary fibrosis in spite of recovery from renal and hepatic toxicity. Conclusion : It is difficult to find out the effect of pulmonary irradiation on the course of the paraquat lung because the precise plasma and urine paraquat concentration were not available between control and irradiation groups. But early pulmonary irradiation within 4 days after paraquat poisoning with aggressive supportive treatment appears to decrease pulmonary toxicity and contribute

  6. Plant-animal interactions in larkspur poisoning in cattle.

    Ralphs, M H; Olsen, J D; Pfister, J A; Manners, G D

    1988-09-01

    Larkspur (Delphinium spp.) toxicity in cattle seriously impedes the efficient use of productive mountain rangelands. Larkspurs contain complex diterpenoid alkaloids that cause acute intoxication and death from respiratory paralysis. Alkaloids and their concentrations vary among larkspur species, plant parts and phenological growth stages, thus causing great variability in toxicity. Ingestion rate of larkspur by the cow, alkaloid toxicity and concentration in the plant and the kinetics of absorption and excretion interact to determine whether a cow is poisoned. Plant and animal factors influencing consumption and subsequent intoxication must be further elucidated to devise management strategies to reduce liverstock losses.

    Allergic contact dermatitis from poison ivy, oak, or sumac is common among people who work or exercise outdoors. The plants, classified in the genus Rhus or Toxicodendron, contain allergens that can cause reactions ranging from mild pruritus to severe urticaria or generalized maculopapular eruptions. Initial management includes cleansing, cold compresses, and, possibly, oral antihistamines for symptomatic relief. Topical corticosteroids are given for localized nonfacial eruptions; systemic corticosteroids are used for severe eruptions. Prevention involves avoiding contact with the plants and washing exposed skin within 2 hours.

    2010-03-01

    Full Text Available Medical audit in general consists of seven steps like choosing topic, setting criterion and standard, collecting first data, comparing data with standard, introducing change, collecting second data and reflecting. Its three basic premise are improvement of patient care by using existing knowledge, team work with ongoing educational process and change management and promotion of blame-free culture maintaining confidentiality. Audit mostly relates to a particular practice and is therefore not generalisable. An audit of residents' late evening routine notes of organophosphate poisoning patients is reported here, as the change introduced appears relevant to the situation of developing countries. Organophosphate poisoning patients should be managed in intensive care unit with close monitoring, as inadvertent stoppage or slowing of atropine infusion may occur, particularly at night, leading to reappearance of poisoning manifestations, which may cause respiratory failure and death. If they are managed in wards, residents-on-duty can check the clinical and intravenous drip status in the late evening and communicate with nurses and relatives to be particularly vigilant. In the audit done, such regular ten pm notes of organophosphate poisoning about the clinical and drip status and communication by residents were increased from 15.5% in the first to 81.7% in the second data collection (p < 0.01 after the introduction of the change. The ten pm note is being continued for about two years now. Implementation of ten pm note of organophosphate poisoning patients admitted in medical wards is feasible and appears useful to improve the quality of health care delivery and learning of residents. Keywords: atrophine, audit, audit steps, organophosphate mortality, organophosphate poisoning.

  11. Cyanide poisoning after bitter almond ingestion

    2013-01-01

    Full Text Available Plants are responsible for 5% poisoning recorded by Poison Control Centers. Among all known toxic plants, some present a real danger if ingested. We report the case of a five years old child, who presented, after ten bitter almonds ingestion, consciousness disorders progressing to coma with generalized tonic-clonic seizures, miosis and metabolic acidosis. Bitter almonds and nuclei of stone fruits or other rosaceae (apricot, peach, plum contain cyanogenic glycosides, amygdalin, that yields hydrogen cyanide when metabolized in the body. Swallowing six to ten bitter almonds may cause serious poisoning, while the ingestion of fifty could kill a man. The binding of cyanide ions on cytochrome oxidase lead to a non hypoxemic hypoxia by blocking the cellular respiratory chain. Therapeutic measures include, oxygen support, correction of acidosis and cyanide antidote by hydroxocobalamin in case of serious poisoning.

    Energy Technology Data Exchange (ETDEWEB)

    Zook, B.C.; Sauer, R.M.; Garner, F.M.

    1972-07-01

    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, 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.

    2009-09-01

    Full Text Available Colchicine is a drug that has been used primarily in several diseases. Colchicine poisoning is an infrequent but potentially life-threatening problem characterized by multiorgan involvement. We present seven children with colchicine poisoning. Their ages ranged between 1 and 9 years. In six children, the amount of colchicine consumed was between 0.16 and 0.39 mg/kg; the most frequent findings were diarrhea and vomiting. In one patient, the ingested amount was unknown. One of the patients died and all others recovered without sequelae. The severity of colchicine poisoning tends to be related to the dosage of ingested drug and the time of admission to hospital. Symptomatic treatment should be started as soon as possible in colchicine poisoning. (Journal of Current Pediatrics 2009; 7: 96-100

  1. Causes of rhabdomyolysis in acute poisonings

    Directory of Open Access Journals (Sweden)

    Janković Snežana R.

    2013-01-01

    Full Text Available Background/Aim. Rhabdomyolysis (RM is potentially lethal syndrome, but there are no enough published data on its frequency and characteristics in acute poisonings. The aim of this study was to determine the causes and severity of RM in acute poisonings. Methods. Patients hospital charts were retrospectively screened during a one-year period in order to identify patients with RM among 656 patients treated due to acute poisonings with different agents. All the patients with RM were selected. Entrance criterion was the value of creatine kinase (CK over 250 U/L. The severity of RM was assessed according to the Poison Severity Score. The patients were divided into three groups: the first one with mild RM (CK from 250 to 1,500 U/L, the second with moderate RM (CK from 1,500 to 10,000 U/L and the third with severe RM (CK greater than 10,000 U/L. Results. RM occurred in 125 (19% of the patients with acute poisonings. It was mainly mild (61%, or moderate (36%, and only in 3% of the patients was severe RM. The incidence of RM was the highest in poisonings with opiates (41%, pesticides (38%, neuroleptics (26%, anticonvulsants (26%, ethyl alcohol (20%, and gases (19%. Psychotropic agents were the most common causes of poisoning, and consequently of RM. Fatal outcomes were registered in 32 (25.60% of all RM patients. The incidence of fatal outcomes in poisonings with mild, moderate and severe RM was 19.73%, 31.11% and 75%, respectively. Conclusion. RM syndrome occurs at a relatively high rate in acute poisonings. Although agent’s toxicity is crucial for the outcome, severe RM and its complications may significantly influence the clinical course and prognosis of poisoning. Routine analysis of CK, as a relevant marker for RM may indicate the development of RM in acute poisoning and initiate prompt therapeutic measures in preventing acute renal failure as the most frequent consequence of extensive rhabdomyolysis.

    Full Text Available Background: 2, 4-dichlorophenoxyacetic acid, (2, 4-D is a selective herbicide available as the acids, esters and several salts which vary in their chemical properties, environmental behaviour, and to a lesser extent toxicity. The salt and ester forms are derivatives of the parent acid. It is widely used as a weed killer. The 2, 4-D dimethylamine is one of the salts of this group. Case Presentation: We report a case of ingestion of 2, 4-D herbicide intentionally. The patient had presented in a local hospital but transferred to our hospital in a state of deep coma. CT scan head showed diffuse cerebral oedema. The patient recovered completely after treatment with forced alkaline diuresis. Discussion: Anticholinesterase compounds are the most commonly used insecticide and the commonest compound used as poison in India. This case report emphasizes that not all poisonings are caused by anticholinesterase compounds. The initial clinical manifestations of 2, 4-dichlorophenoxyacetic acid (2, 4-D poisoning are very similar to alcohol, sedative drugs, or aromatic chlorinated hydrocarbons making it even more difficult for the treating physician to suspect poisoning due to these compounds. It is thus important to identify the correct compound for proper management. Prompt diagnosis and correct treatment can save the life of a patient. The poisoning is also sometimes confused with poisoning due to anticholinesterase compound. Conclusion: 2, 4-D is a poison which carries a high mortality. Prolonged coma, metabolic complications, skeletal muscle injury and myotonia are some of the complications of 2, 4-D. Forced alkaline diuresis resulted in saving our patient which otherwise had poor prognosis.

    Full Text Available Purpose: Acute exposure to a systemic poison represents an important segment of medical emergencies. We aimed to estimate the likelihood of systemic poison-induced morbidity in a population admitted in a tertiary referral center from North East Romania, based on the determinant factors. Methodology: This was a prospective observational cohort study on adult poisoned patients. Demographic, clinical and laboratory characteristics were recorded in all patients. We analyzed three groups of patients, based on the associated morbidity during hospitalization. We identified significant differences between groups and predictors with significant effects on morbidity using multiple multinomial logistic regressions. ROC analysis proved that a combination of tests could improve diagnostic accuracy of poison-related morbidity. Main findings: Of the 180 patients included, aged 44.7 ± 17.2 years, 51.1% males, 49.4% had no poison-related morbidity, 28.9% developed a mild morbidity, and 21.7% had a severe morbidity, followed by death in 16 patients (8.9%. Multiple complications and deaths were recorded in patients aged 53.4 ± 17.6 years (p .001, with a lower Glasgow Coma Scale (GCS score upon admission and a significantly higher heart rate (101 ± 32 beats/min, p .011. Routine laboratory tests were significantly higher in patients with a recorded morbidity. Multiple logistic regression analysis demonstrated that a GCS < 8, a high white blood cells count (WBC, alanine aminotransferase (ALAT, myoglobin, glycemia and brain natriuretic peptide (BNP are strongly predictive for in-hospital severe morbidity. Originality: This is the first Romanian prospective study on adult poisoned patients, which identifies the factors responsible for in-hospital morbidity using logistic regression analyses, with resulting receiver operating characteristic (ROC curves. Conclusion: In acute intoxication with systemic poisons, we identified several clinical and laboratory variables

    The burnability of raw materials and the quality of clinkers can be affected while too much quartz in raw material. Quartz will be brought in raw materials inevitably while the all components of waste concrete were used in cement production. Different proportions of slag were mixed in raw material in the experiment, the effect of slag on the clinker property and the burnability of raw material whose silicon materials were ISO standard sand was studied. The ethanol-glycol method was used to analyze the content of f-CaO, clinker minerals were identified by XRD, mineral morphology was observed by metalloscope, cement paste specimen were produced to test the compressive strength of hydrated clinker. The result showed that the burnability of raw materials with high quartz content was notably improved while adding the slag, slag also improved the formation of clinker mineral, while the amount of slag in raw materials was 3% ,hydrated clinker has the highest comprehensive strength; clinker produced more C-S-H gel and AFt in early hydration and C-S-H gel can be much denser in late hydration while moderate slag added in the raw materials.%利用含砂废弃混凝土原料煅烧水泥熟料,不可避免地会由细骨料砂引入结晶度较高的结晶态SiO2,不仅影响生料易烧性,而且影响硅酸盐矿物的组成和形貌,降低熟料质量.以ISO标准砂为硅质原料配制高结晶态SiO2含量的生料,按不同比例掺入矿渣,煅烧至不同温度;利用化学分析、XRD、岩相分析、SEM等方法,研究矿渣对水泥生料易烧性、熟料矿物组成和显微结构、熟料水化强度发展及水化产物形貌的影响.结果表明,适量矿渣的掺入可显著改善高结晶态SiO2含量水泥生料的易烧性,促进熟料矿物形成和发育;矿渣掺量为3%时,熟料水化后强度最高;适量矿渣可使熟料水化早期产生较多的C-S-H凝胶和钙矾石,而后期水化产物中C-S-H凝胶更密实,提高水泥强度.

  10. Aluminum phosphide poisoning: an unsolved riddle.

    Anand, R; Binukumar, B K; Gill, Kiran Dip

    2011-08-01

    Aluminum phosphide (ALP), a widely used insecticide and rodenticide, is also infamous for the mortality and morbidity it causes in ALP-poisoned individuals. The toxicity of metal phosphides is due to phosphine liberated when ingested phosphides come into contact with gut fluids. ALP poisoning is lethal, having a mortality rate in excess of 70%. Circulatory failure and severe hypotension are common features of ALP poisoning and frequent cause of death. Severe poisoning also has the potential to induce multi-organ failure. The exact site or mechanism of its action has not been proved in humans. Rather than targeting a single organ to cause gross damage, ALP seems to work at the cellular level, resulting in widespread damage leading to multiorgan dysfunction (MOD) and death. There has been proof in vitro that phosphine inhibits cytochrome c oxidase. However, it is unlikely that this interaction is the primary cause of its toxicity. Mitochondria could be the possible site of maximum damage in ALP poisoning, resulting in low ATP production followed by metabolic shutdown and MOD; also, owing to impairment in electron flow, there could be free radical generation and damage, again producing MOD. Evidence of reactive oxygen species-induced toxicity owing to ALP has been observed in insects and rats. A similar mechanism could also play a role in humans and contribute to the missing link in the pathogenesis of ALP toxicity. There is no specific antidote for ALP poisoning and supportive measures are all that are currently available.

    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.

  12. Toad poisoning in three dogs: case reports

    Directory of Open Access Journals (Sweden)

    2009-01-01

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

    Self-poisoning with plant seeds or fruits is a common method of self-harm in South Asia. While most deaths follow ingestion of Thevetia peruviana (yellow oleander) seeds, other plants are locally common. During review of fatal injuries seen in a teaching hospital in eastern Sri Lanka, we noted cases of fatal self-poisoning with Cerbera manghas (sea mango, pink eyed cerbera, odollam tree) fruits. We reviewed the post-mortem records of the Batticaloa Teaching Hospital and extracted data on all cases of fatal injury. During 2001 and 2002, 315 post mortems for injury were performed in Batticaloa Teaching Hospital. Intentional self-harm was responsible for 48.6% of cases. While T. peruviana was responsible for 33 deaths, C. manghas self-poisoning caused seven deaths. C. manghas cases had typical features of cardenolide poisoning with cardiac dysrhythmias and hyperkalemia. In the absence of pacing facilities and anti-digoxin Fab, management involved administration of atropine and of insulin and dextrose to lower serum potassium concentrations. C. manghas self-poisoning has only previously been reported from Kerala and Tamil Nadu in south India. While uncommon in other parts of Sri Lanka, it has become a common method of self-harm in one east coast district, accounting for 20% of fatal self-harm with plants in one hospital. Management was inadequate with the available resources, emphasising the need for an affordable antitoxin for plant cardenolide poisoning.

    Full Text Available Background: To investigate the risk factors of child lead poisoning in China. Methods: A document retrieval was performed using MeSH (Medical subject heading terms and key words. The Newcastle-Ottawa Scale (NOS was used to assess the quality of the studies, and the pooled odd ratios with a 95% confidence interval were used to identify the risk factors. We employed Review Manager 5.2 and Stata 10.0 to analyze the data. Heterogeneity was assessed by both the Chi-square and I2 tests, and publication bias was evaluated using a funnel plot and Egger’s test. Results: Thirty-four articles reporting 13,587 lead-poisoned children met the inclusion criteria. Unhealthy lifestyle and behaviors, environmental pollution around the home and potential for parents’ occupational exposure to lead were risk factors of child lead poisoning in the pooled analyses. Our assessments yielded no severe publication biases. Conclusions: Seventeen risk factors are associated with child lead poisoning, which can be used to identify high-risk children. Health education and promotion campaigns should be designed in order to minimize or prevent child lead poisoning in China.

    The purpose of this retrospective study was to analyse the etiology, frequency and outcome of toxicological cases recorded by the consultation service of the Swiss Toxicological Information Centre (STIC) hotline over a 10-year period, from 1997 to 2006. A detailed analysis of this database indicates that common human drugs not intended for use in animals, as well as pesticides and toxic plants represent the most prominent hazards involved in the reported cases of animal poisonings. The comparison with a previous survey from the years 1976 - 1985 revealed new toxic risks due to the accidental uptake of cannabis products, castor seeds or chocolate by dogs. In addition, there is a striking increase of serious poisonings with pyrethroids in cats. The follow-up reports delivered by veterinarians also reflect novel pharmacological and technological trends in the management of poisonings.

    Lead is a metal that has no biological function useful for the human body. In Korea, non-occupational exposure to lead has mostly occurred through taking oriental medicine. However, in this paper we report a case of lead poisoning caused by ingesting talisman material. A 16-year-old male patient complained of severe abdominal pain after taking cinnabar, a talisman material. He was diagnosed with lead poisoning accompanied by acute hepatitis. We confirmed that the cinnabar the patient took contained about 10% elemental lead. After symptom management, the patients' symptoms, liver function test results, and blood lead concentration level improved. Lead poisoning can be accompanied by hepatitis, although rarely. As we have confirmed that cinnabar as a talisman material is harmful to the human body, measures to prevent its misuse are needed.

    In this study nine cases of thallium poisoning in a series of homicidal poisoning were analyzed in order to provide more information concerning thallium poisoning. It was found that the most common clinical feature of thallium poisoning was peripheral neuropathy and paraesthesia was more common than amyasthenia. Understanding of these clinical characteristics of thallium poisoning was helpful to early identification and differential diagnosis. Since the early administration of Prussian Blue, as a specific antidote for thallium poisoning, can substantially improve the prognosis, it is of great importance to establish a correct and early diagnosis.

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

    2006-10-01

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

    2009-01-01

    @@ The idea that to eat certain two foods simultaneously is to get poisoned has been entertained by柄Chinese people for many years. There are about 184 pairs of the so-called poisonous food-combinations, and 180 of them are mentioned in Chinese Ancient Materia Medica, Ben-Tsao-Gung-Mu (本草纲目) or other books. (1a,2a) This belief was based upon some personal sketch, old-fashioned doctors' notes, stories and other false facts. Although these statements were originated without any experimental ground, yet many of the Chinese, even at present time, still believe them firmly. Whenever any poisoning outbreak occurs accidentally after having taken the so-called poisonous food-combination, they always attribute the cause of the poisoning to the two foods served simultaneously.

    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.

  5. Prairie dog poisoning in northern Great Plains: An analysis of programs and policies

    Roemer, David M.; Forrest, Steven C.

    1996-05-01

    This paper describes the programs and policies regarding prairie dog control in the northern Great Plains states of Montana, South Dakota, and Wyoming. The poisoning programs of federal and state agencies are described, along with the statutes and legal mandates that shape agency management of prairie dogs. Current policies on National Grasslands and other federal lands typically limit prairie dogs to small percentages of available potential habitat, to the detriment of prairie dogs and associated species. State programs to assist landowners in prairie dog control differ greatly, employing cost-share incentives (Wyoming) and regulatory fines (South Dakota) to encourage the poisoning of prairie dogs. Prairie dog control is not actively funded or practiced by state or county agencies in Montana. We document federal and state involvement in more than 1 million acres of prairie dog poisoning in the study area during 1978 1992. In combination with undocumented poisoning by private landowners, plague, and shooting, prairie dogs may be experiencing net regional declines, contributing to the disintegration of the prairie dog ecosystem. We recommend that Animal Damage Control operations concerning prairie dogs be terminated, on the basis that they duplicate state programs and are at cross purposes with federal wildlife management programs that seek to perpetuate and/or recover wildlife species that depend on the prairie dog ecosystem. We further recommend that federal range improvement funds be offered as subsidies for the integration of prairie dogs in range management, as opposed to funding prairie dog eradication programs.

    Our environment hosts a vast diversity of venomous and poisonous animals and plants. Clinical toxinology is devoted to understanding, preventing and treating their effects in humans and domestic animals. In Sri Lanka, yellow oleander (Thevetia peruviana, Sinhala 'kaneru'), a widespread and accessible ornamental shrub, is a popular means of self-harm. Its toxic glycosides resemble those of foxglove, against which therapeutic antibodies have been raised. A randomised placebo-controlled trial proved that this treatment effectively reversed kaneru cardiotoxicity. There are strong scientific grounds for the use of activated charcoal, but encouraging results with multiple-dose activated charcoal were not confirmed by a recent more powerful study. Venom of Russell's viper (Daboia siamensis) in Burma (Myanmar) produces lethal effects in human victims. The case of a 17-year-old rice farmer is described with pathophysiological interpretations. During the first 9 days of hospital admission he suffered episodes of shock, coagulopathy, bleeding, acute renal failure, local tissue necrosis, generally increased capillary permeability and acute symptomatic hypoglycaemia with evidence of acute pituitary/adrenal insufficiency. Antivenom rapidly restored haemostatic function but failed to correct other effects of venom toxins incurred during the 3h before he could be treated.

    Lead in its various forms has been used for thousands of years, originally in cooking utensils and glazes and more recently in many industrial and commercial applications. However, lead is a potent, potentially deadly toxin that damages many organs in the body and can affect all animals, including humans. By the mid 1990s, lead had been removed from many products in the United States, such as paint and fuel, but it is still commonly used in ammunition for hunting upland game birds, small mammals, and large game animals, as well as in fishing tackle. Wild birds, such as mourning doves, bald eagles, California condors, and loons, can die from the ingestion of one lead shot, bullet fragment, or sinker. According to a recent study on loon mortality, nearly half of adult loons found sick or dead during the breeding season in New England were diagnosed with confirmed or suspected lead poisoning from ingestion of lead fishing weights. Recent regulations in some states have restricted the use of lead ammunition on certain upland game hunting areas, as well as lead fishing tackle in areas frequented by common loons and trumpeter swans. A variety of alternatives to lead are available for use in hunting, shooting sports, and fishing activities.

    Full Text Available Background: Marine neurotoxins as of Marine biotoxins are natural toxins that produced mainly by dinoflagellates, diatoms and several species of invertebrates and fish. Marine poisoning results from the ingestion of marine animals contain these toxins and causes considerable adverse effects. Materials and methods: This review provides some facts about the structures of marine neurotoxins, their molecular target and pharmacology, analytical methods for their detection and quantitation, diagnosis and laboratory testing, clinical manifestations, as well as prevention and treatment, if were obtainable. Furthermore, we focus on marine poisoning and various associated neurological syndromes like ciguatera, tetrodotoxin poisoning, and paralytic shellfish poisoning, after ingestion of the common marine toxins. Results: A number of neurotoxins that prescribed according to their potency (LD50 are: Maitotoxin, Ciguatoxins and Palytoxin, Tetrodotoxin and Saxitoxin, Brevetoxins, Azaspiracid, Yessotoxin, Cooliatoxin, Domoic acid and Conotoxins, Respectively. The primary target of most marine neurotoxins is voltage gated sodium channels and the resulting block of ion conductance through these channels. Moreover, these compounds interact with voltage-gated potassium and calcium channels and modulate the flux of stated ions into many cell types. As well, the target recognized for palytoxin is the Na+- K+ /ATPase. Conclusion: Results of reviewed studies revealed that, the Ciguatera is the commonest syndrome of marine poisoning, but is rarely lethal. Puffer fish poisoning results from the ingestion of fish containing tetrodotoxin and paralytic shellfish poisoning are less common, but have a higher fatality rate than ciguatera. Despite their high toxicity, no much research has been done on some of the toxins, like maitotoxin. In addition, there have remained unknown the pharmacological effects, mechanism of action and molecular target of some toxins such as

    Full Text Available Paralytic shellfish poisoning (PSP, due to saxitoxin and related compounds, typically results from the consumption of filter-feeding molluscan shellfish that concentrate toxins from marine dinoflagellates. In addition to these microalgal sources, saxitoxin and related compounds, referred to in this review as STXs, are also produced in freshwater cyanobacteria and have been associated with calcareous red macroalgae. STXs are transferred and bioaccumulate throughout aquatic food webs, and can be vectored to terrestrial biota, including humans. Fisheries closures and human intoxications due to STXs have been documented in several non-traditional (i.e. non-filter-feeding vectors. These include, but are not limited to, marine gastropods, both carnivorous and grazing, crustacea, and fish that acquire STXs through toxin transfer. Often due to spatial, temporal, or a species disconnection from the primary source of STXs (bloom forming dinoflagellates, monitoring and management of such non-traditional PSP vectors has been challenging. A brief literature review is provided for filter feeding (traditional and nonfilter feeding (non-traditional vectors of STXs with specific reference to human effects. We include several case studies pertaining to management actions to prevent PSP, as well as food poisoning incidents from STX(s accumulation in non-traditional PSP vectors.

    1997-05-01

    The NRC staff has reviewed a report, submitted by DOE to determine whether the use of a commercial light-water reactor (CLWR) to irradiate a limited number of tritium-producing burnable absorber rods (TPBARs) in lead test assemblies (LTAs) raises generic issues involving an unreviewed safety question. The staff has prepared this safety evaluation to address the acceptability of these LTAs in accordance with the provision of 10 CFR 50.59 without NRC licensing action. As summarized in Section 10 of this safety evaluation, the staff has identified issues that require NRC review. The staff has also identified a number of areas in which an individual licensee undertaking irradiation of TPBAR LTAs will have to supplement the information in the DOE report before the staff can determine whether the proposed irradiation is acceptable at a particular facility. The staff concludes that a licensee undertaking irradiation of TPBAR LTAs in a CLWR will have to submit an application for amendment to its facility operating license before inserting the LTAs into the reactor.

    Organophosphates are insecticides which are widely used as a suicidal agent in Iran. They are associated with different types of cardiac complications including cardiac arrest and arrhythmia, however their role in cardiac injury is not known yet. The aim of this study was to investigate the presence of myocardial damage in patients with cholinesterase poisoning.It was a prospective study conducted from January 2008 to March 2010. Cohorts of patients with cholinesterase poisoning due to suicidal attempt who have been referred to Loghman hospital were selected. Patients who have taken more than one poison or were used concomitant drugs were excluded. Physical examination was performed on admission to discover warning sign. Peripheral arterial blood gases, creatine kinase, creatine kinase-myocardial band, troponin-T measurements were performed in all cases. There were 24 patients, 7 of them women, with the mean age of 41.2±15.05 who were included in this study. Non-survivors had significantly higher levels of systolic blood pressure, partial pressure of oxygen in arterial blood, partial pressure of carbon dioxide, bicarbonate Glasgow Coma Scale scoring and longer duration of mechanical ventilation. Our findings showed that cardiac injury is an important cause of death in organophosphate poisoning. It could be hypothesized that cardiac injury is a strong predictor of death in patients with organophosphate poisoning.

  13. Pancreatitis in wild zinc-poisoned waterfowl

    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.

  14. Hypotension in Severe Dimethoate Self-Poisoning

    Introduction Acute self-poisoning with the organophosphorus (OP) pesticide dimethoate has a human case fatality three-fold higher than poisoning with chlorpyrifos despite similar animal toxicity. The typical clinical presentation of severe dimethoate poisoning is quite distinct from that of chlorpyrifos and other OP pesticides: many patients present with hypotension that progresses to shock and death within 12–48 h post-ingestion. The pathophysiology of this syndrome is not clear. Case reports We present here three patients with proven severe dimethoate poisoning. Clinically, all had inappropriate peripheral vasodilatation and profound hypotension on presentation, which progressed despite treatment with atropine, i.v. fluids, pralidoxime chloride, and inotropes. All died 2.5–32 h post-admission. Continuous cardiac monitoring and quantification of troponin T provided little evidence for a primary cardiotoxic effect of dimethoate. Conclusion Severe dimethoate self-poisoning causes a syndrome characterized by marked hypotension with progression to distributive shock and death despite standard treatments. A lack of cardiotoxicity until just before death suggests that the mechanism is of OP-induced low systemic vascular resistance (SVR). Further invasive studies of cardiac function and SVR, and post-mortem histology, are required to better describe this syndrome and to establish the role of vasopressors and high-dose atropine in therapy.

    2010-02-01

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

    Objective To describe the use of poison center data for public health surveillance from the poison center, local, state, and federal public health perspectives and to generate meaningful discussion on how to address the challenges to collaboration. Introduction Since 2008, poisoning has become the leading cause of injury-related death in the United States (US); since 1980, the poisoning-related fatality rate in the US has almost tripled.1 Many poison-related injuries and deaths are reported to regional poison centers (PCs) which receive about 2.4 million reports of human chemical and poison exposures annually.2 Federal, state, and local public health (PH) agencies often collaborate with poison centers and use PC data for public health surveillance of poisoning-related health issues. Many state and local PH agencies have partnerships with regional PCs for direct access to local PC data which help them perform this function. At the national level, CDC conducts public health surveillance for exposures and illnesses of public health significance using the National Poison Data System (NPDS), the national PC reporting database. Though most PC and PH officials agree that PC data play an important role in PH practice and surveillance, collaboration between PH agencies and PCs has been hindered by numerous challenges. To address these challenges and bolster collaboration, the Poison Center and Public Health Collaborations Community of Practice (CoP) was created in 2010 by CDC as a means to share experiences, identify best practices, and facilitate relationships among federal, state and local public health agencies and PCs. To date, the Poison Center and Public Health Collaborations CoP includes over 200 members from state and local public health, regional PCs, CDC, the American Association of Poison Control Centers (AAPCC), and the Environmental Protection Agency (EPA). A leadership team was created with representatives of the many stakeholders of the community to drive its

    Ergotamine is a well known pharmacological remedy applied in neurology (treatment of vascular headache) and in obstetrics (abortive remedy, uterus atony). But today it is rarely used, because of new safer anti-migraine medicine (triptanes) which cause fewer side effects. According to obstetrical indications ergotamine is applied only in hospital treatment. For that reason, cases of intoxication by this class of drugs are rarely observed. Ergotamine causes constriction of the blood vessels through the blockade of alpha-receptors and stimulation of the serotonin-receptors on the walls of blood vessels both in the central nervous system and in peripheral circulation. Intoxication/overdose symptoms may appear on application of therapeutic dose by sensitive patients, mostly by patients with migraine headache using ergotamine preparation for relief of migraine attacks. In the Regional Centre of Clinical Toxicology, a 21-year-old patient was hospitalized. She took about 20 tablets of Cafergot (complex preparation containing 1mg ergotamine tartare and 100mg caffeine). During her stay on the ward, typical symptoms of severe poisoning were observed: nausea, severe vomiting, dizziness, decreased blood pressure without perceptible pulse, narrowing of the blood vessels in the extremities of the body (peripheral vasoconstriction) - paresthesia, digital cyanosis, refrigeration of legs, angina. Due to taking once of a great dose of the drug by the patient, violent process of intoxication, possibility of dangerous complication and also the unavailability of specific antidotes and lack of efficient methods of extracorporeal elimination of the drug, the patient was intensively controlled and symptomatic treatments according to the law of intensive therapy was applied.

    A 31-year-old man with a history of alcohol abuse presented to the accident and emergency department complaining of blurred vision. 4 h previously he had drunk 300 mL de-icer fluid. Electrolytes, urea, creatinine, glucose, and blood-gas analysis were normal. Measured osmolality, however, was 368 mosmol/kg with a calculated osmolality of 300 mosmol/kg, which indicated a greatly increased osmolar gap. He was therefore given 150 mL whisky and admitted. Methanol was later reported as 200 mg/dL. Ethylene glycol was not detected, but another glycol, propylene glycol, was present at 47 mg/dL. 10 h after ingestion an intravenous infusion of ethanol was started and he was hemodialysed for 7 h. After dialysis he was given a further 100 mL whisky and the rate of ethanol infusion was reduced to 11 g per h. Methanol and ethanol were measured twice daily until methanol was under 10/mg/dL: The recommendation is that blood ethanol be maintained between 100 and 200 mg/dL during treatment of methanol poisoning. This concentration was not achieved, presumably because of the high rate of ethanol metabolism often found in alcoholics. Antifreeze solutions commonly contain methanol and ethylene glycol. Sometimes propylene glycol is substituted because it has properties similar to those of ethylene glycol but is less toxic. The authors postulate that propylene glycol inhibited the metabolism of methanol in the patient, thus sparing him from the toxic effects of methanol.

    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.

    2007-01-01

    The paper presents toxicological characteristics of 198 cases of acute parenteral heroin intoxication, analyzes the clinically encountered range of blood and urinary concentrations of its metabolites. The principal causes of death are elucidated in victims of heroin poisoning at the hospital stage. Where there is a relationship of death probability to the detection of morphine in the victims' biological fluids is considered; its blood and urinary concentrations are determined, which undoubtedly suggests the occurrence of poisoning-related death. It has been established that death from poisoning by heroin may occur in the whole range of its detectable concentrations. There is no doubt that the blood morphine concentrations of at least 2.0 microg/ml should be considered to be fatal.

    Terrorist use of organophosphorus-based nerve agents and toxic industrial chemicals against civilian populations constitutes a real threat, as demonstrated by the terrorist attacks in Japan in the 1990 s or, even more recently, in the Syrian civil war. Thus, development of more effective countermeasures against acute organophosphorus poisoning is urgently needed. Here, we have generated and validated zebrafish models for mild, moderate and severe acute organophosphorus poisoning by exposing zebrafish larvae to different concentrations of the prototypic organophosphorus compound chlorpyrifos-oxon. Our results show that zebrafish models mimic most of the pathophysiological mechanisms behind this toxidrome in humans, including acetylcholinesterase inhibition, N-methyl-D-aspartate receptor activation, and calcium dysregulation as well as inflammatory and immune responses. The suitability of the zebrafish larvae to in vivo high-throughput screenings of small molecule libraries makes these models a valuable tool for identifying new drugs for multifunctional drug therapy against acute organophosphorus poisoning.

    The role of public health surveillance in disaster response continues to expand as timely, accurate information is needed to mitigate the impact of disasters. Health surveillance after a disaster involves the rapid assessment of the distribution and determinants of disaster-related deaths, illnesses, and injuries in the affected population. Public health disaster surveillance is one mechanism that can provide information to identify health problems faced by the affected population, establish priorities for decision makers, and target interventions to meet specific needs. Public health surveillance traditionally relies on a wide variety of data sources and methods. Poison center (PC) data can serve as data sources of chemical exposures and poisonings during a disaster. In the US, a system of 57 regional PCs serves the entire population. Poison centers respond to poison-related questions from the public, health care professionals, and public health agencies. The Centers for Disease Control and Prevention (CDC) uses PC data during disasters for surveillance of disaster-related toxic exposures and associated illnesses to enhance situational awareness during disaster response and recovery. Poison center data can also be leveraged during a disaster by local and state public health to supplement existing surveillance systems. Augmenting traditional surveillance data (ie, emergency room visits and death records) with other data sources, such as PCs, allows for better characterization of disaster-related morbidity and mortality. Poison center data can be used during a disaster to detect outbreaks, monitor trends, track particular exposures, and characterize the epidemiology of the event. This timely and accurate information can be used to inform public health decision making during a disaster and mitigate future disaster-related morbidity and mortality. PMID:25205009

    Full Text Available BACKGROUND Accidents including poisoning are one of the leading causes of morbidity and mortality among children in the west. Poisoning, while never accounting for a large number of accidental deaths, have acquired prominence now because they have not decreased at the same rate as the infectious diseases. METHODS An observational study was done in Department of Paediatrics KIMS Bangalore to know the incidence and pattern of childhood poisoning, to know the morbidity and mortality resulting from childhood poisoning. 86 children aged between 0-18 years were admitted to the paediatric intensive care unit with history of poisoning during the 2-year period of the study (Nov 13-Nov 15 were included. Diagnosis of poisoning was made on the basis of history and examination findings, Relevant investigations were done and Profile of patients with poisoning, their symptoms, type of poisoning and outcome were analysed. RESULTS The average duration of stay in the hospital was 2.7 days. Poisoning was accidental in 80 (93% patients whereas suicidal intent was present in only 6 (7% patients. Total 5 (5.8% patients died of which 4 were due to insecticide and pesticide poisoning and one was due to kerosene poisoning. CONCLUSION In the present study the probable reason for higher incidence of poisoning by insecticides & pesticides could be the involvement of higher age group and more involvement of adolescent children.

    Toloxatone is a new monoamine oxidase inhibitor. One hundred and twenty two cases of poisoning with this drug are reported. In this series, the minimal toxic dose was 2 g. The first symptoms appeared about one hour after ingestion. In most cases, only drowsiness and mild adrenergic effects were observed. In a few cases of massive overdose, coma, pyramidal irritation, and myoclonic jerks occurred. In 3 cases of severe poisoning, toloxatone was associated with tricyclic antidepressants. Symptoms were similar to those reported in intoxications associating classical monoamine oxidase inhibitors and tricyclic antidepressants: muscular rigidity, hyperthermia and cardiovascular collapse. Two of these patients died.

    One hundred and three children with kerosene poisoning were studied. The majority of the patients were under five years of age and included a newborn baby. More patients were seen in spring and fewer in winter months. Most of the patients were children of poor families living in overcrowded conditions. Negligence and ignorance were the main causes of poisoning. Respiratory and central nervous systems were mainly involved. Chest X-ray abnormalities were frequently seen. The patients were treated symptomatically. Only one patient died, he had been in a coma on admission to the hospital. All other patients had rapid and complete recoveries. PMID:7567734

    A case of group poisoning from the consumption of the fish Sarpa salpa, caught in the Mediterranean coastal waters of Israel, is presented. Mullets and rabbitfish caught at the same site caused no harm. This is the third case of ciguatera poisoning in the region and the first to be transferred by a fish which is not a Red Sea immigrant. It implies that toxic algae dinoflagellates, originating from the Red Sea, crossed the Suez Canal and found their way to the Mediterranean coastal waters.

    1994-01-01

    The case of a zoo keeper who was bitten on the left finger by a venomous snake (Vipera xanthina) is reported. The administration of antivenom prevented the development of systemic poisoning but had no effect on the extent of the local complications. A compartment syndrome with a concomitant severe reaction at the bite site required fasciotomy of the upper and lower arm. The extensor tendon of the involved finger ruptured spontaneously, many weeks after wound healing was completed. Therefore, delayed local complications following snake bites may occur, even if signs of systemic poisoning are missing.

    Full Text Available Sulphur mustard is a chemical warfare agent, which was largelyused during the World War One and in Iraq-Iran conflict. It mayalso be used as a chemical terrorism agent. Therefore, medicalprofessions should have sufficient knowledge and be preparedfor medical intervention of any such chemical attack.Sulphur mustard exerts direct toxic effects on the eyes, skin,and respiratory tract, with subsequent systemic actions on thenervous, immunologic, hematologic, digestive, and reproductivesystems. It is an alkylating agent that affects DNA synthesis andthus, delayed complications have been considered since theWorld War One. Cases of malignancies in the target organs particularlyin hematopoietic, respiratory, and digestive systemswere reported. Common delayed respiratory complications includechronic bronchitis, bronchiectasis, frequent bronchopneumonia,and pulmonary fibrosis, all of which tend to deterioratewith time. Severe dry skin, delayed keratitis, and reduction ofnatural killer cells with subsequent increased risk of infectionsand malignancies are also among the most distressing long-termconsequences of sulphur mustard intoxication. However, despiteextensive research that has been conducted on Iranian veteransduring the past decades, major gaps continue to remain in thesulphur mustard literature. Immunological and neurological dysfunctionsand the relationship between exposure to sulphur mustardand mutagenicity, carcinogenicity, and teratogenicity areimportant fields that require further studies, particularly on Iranianveterans with chronic health problems caused by sulphurmustard poisoning. There is also a paucity of information on themedical management of acute and delayed toxic effects of sulphurmustard poisoning, a subject that greatly challenges themedical professions.

    Full Text Available Background: Tramadol, an analgesic drug abused by opioid addicts, is also abused accidentally or for suicidal purposes. Tramadol poisoning can induce CNS depression, seizures, coma, and ultimately death. Case: In this report, a 30-year-old male was admitted to the emergency department due to suicidal attempt with ingestion of 14000 mg (140 tablet 100 mg of tramadol. He had history of suicidal attempts in past years as well as depression in his past medical history, but he had not abused tramadol and other drugs in his history. There was no history of epilepsy or head trauma in. He presented with generalized seizures two hours post ingestion, and, then, he was referred to hospital four hours later. Generalized seizures were poorly controlled by multiple medications. Due to respiratory arrest, endotracheal tube was inserted and he was admitted to the ICU immediately. At admission, he experienced hypovolemic shock, hypoglycemia, coma, apnea, refractory seizures, muscle spasms, acute respiratory distress syndrome, coagolative disorder, rhabdomyolysis, and acute renal failure. Despite medical managements, he died 38 days after ingestion. Conclusion: In this report, despite using inhalational anesthetic drugs, seizures continued and were very poorly controlled. Cause of death in this patient can be seen as the side effects of tramadol poisoning.

  6. Ciguatera fish poisoning in the Caribbean islands and Western Atlantic.

    Science.gov (United States)

    Pottier, I; Vernoux, J P; Lewis, R J

    2001-01-01

    Ciguatera fish poisoning (ciguatera), a common poisoning caused by fish ingestion, is reviewed in the Western Atlantic and the Caribbean waters. It is endemic from Florida coasts (northern limit) to Martinique Island (southern limit), with outbreaks occurring from time to time. In the Caribbean, ciguatera causes a polymorphic syndrome with gastrointestinal, cardiovascular, and neurological signs and symptoms. Neurological and muscular dysfunctions can be treated by intravenous injection of D-mannitol. The lipid-soluble toxins involved are ciguatoxins that are likely produced by the dinoflagellate Gambierdiscus toxicus. G. toxicus strains are endemic in the Caribbean Sea and in theWestern Atlantic. Although it is likely that blooms of G. toxicus are ingested by herbivorous fishes, they are not implicated in ciguatera in the Caribbean. Rather, large carnivores (barracudas, jacks, snappers, groupers), consumers of smaller benthic fish, are often involved in ciguatera. Fish toxicity depends on fishing area and depth, fish size and tissues, and climatic disturbances. Ciguatoxins have been isolated and purified from Caribbean fish species. The structure of two epimers, C-CTX-1 and C-CTX-2 from horse-eye jack, comprise 14 trans-fused ether-linked rings and a hemiketal in terminal ring. Caribbean ciguatoxins are mainly detected in the laboratory by chicken, mouse, mosquito, or cell bioassays, and by analytical HPLC/tandem mass spectrometry down to parts per billion (ppb). A ciguatera management plan that integrates epidemiology, treatment, and a simple method of detection is required to ensure the protection of consumers.

    Raw or dried gallbladders of cyprinid fish have long been ingested as a traditional medicine in the Asian countries, particularly in China, for ameliorating visual acuity, rheumatism, and general health; however, sporadic poisoning incidences have occurred after their ingestion. The poisoning causes complex symptoms in patients, including acute renal failure, liver dysfunction, paralysis, and convulsions of limbs. The causative substance for the poisoning was isolated, and its basic properties were examined. The purified toxin revealed a minimum lethal dose of 2.6 mg/20 g in mouse, when injected intraperitoneally. The main symptoms were paralysis and convulsions of the hind legs, along with other neurological signs. Liver biopsy of the euthanized mice clearly exhibited hepatocytes necrosis and infiltration of neutrophils and lymphocytes, suggesting the acute dysfunction of the liver. Blood tests disclosed the characteristics of acute renal failure and liver injury. Infrared (IR) spectrometry, fast atom bombardment (FAB) mass spectrometry, and 1H- and 13C-nuclear magnetic resonance (NMR) analysis indicated, a molecular formula of C27H48O8S, containing a sulfate ester group for the toxin. Thus, we concluded that the structure of carp toxin to be 5α-cyprinol sulfate (5α-cholestane-3α, 7α, 12α, 26, 27-pentol 26-sulfate). This indicated that carp toxin is a nephro- and hepato- toxin, which could be the responsible toxin for carp bile poisoning in humans.

    2016-02-01

    Full Text Available 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%.

    2013-09-01

    Full Text Available This work aims to analyze the epidemiological profile of human poisoning by rodenticides in Brazil and Regions, in the period 2000 to 2008. This is a descriptive epidemiological study based on secondary data from the National System of Toxic- harmacological Information. Calculations were performed in the incidence rate and fatality rate. The North and Northeast regions had the highest mortality rates for the period. Children from 1 to 4 years had high incidence in all regions except in Northeast, where teenagers were most affected. The rodenticide poisoning was more incident in urban areas and among females, and had attempt suicide as predominant circumstance. Although most cases have evolved for healing, there was almost 40% unconfirmed healing in the South region and 57% of ignored evolution in Southeast. Deaths caused by ingestion of rodenticides were below 5%. The rodenticide poisoning has remained in Brazil with a major public health problem and, despite the differences in the country, the poisoning profile did not change significantly between different regions.

  15. Brachiaria spp. poisoning of ruminants in Brazil

    Directory of Open Access Journals (Sweden)

    B. Riet-Correa

    2011-03-01

    Full Text Available Brachiaria species are the most important grasses for cattle production in Brazil. However, a limiting factor for the use of Brachiaria spp. is their toxicity. Most outbreaks of hepatogenous photosensitization are caused by B. decumbens; however B. brizantha, B. humidicola and B. ruziziensis can also cause poisoning. The poisoning affects cattle, sheep, goats and buffalo. Sheep are more susceptible than other animal species and the young are more susceptible than adults. There are differences in susceptibility among animals of the same species and it has been suggested that this resistance is genetic. Also has been suggested that buffalo and probably some sheep are resilient, i.e. when poisoned these animals have histologic lesions and high GGT serum concentrations, but do not show clinical signs. In general, saponin concentrations are higher in growing plants, but outbreaks occur all over the year, probably due to unexplained rise in saponin concentration in the plant. A clinical syndrome of progressive weight loss and death, without photosensitization, has been reported in cattle poisoned by B. decumbens. Main preventive measures are based on the selection of resistant or resilient animals and on the development of Brachiaria species or varieties with low saponin concentration.

    Directory of Open Access Journals (Sweden)

    Radenkova-Saeva J.

    2014-06-01

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

    2017-01-01

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

    Mercury is a toxic metal that is widely used in everyday life. It has organic and inorganic forms that are both toxic. As acute mercury poisoning is uncommon, diagnosis is difficult if the exposure is not manifest. It has usually a slow onset and non-specific symptoms. In this paper we report a patient who developed polyarthritis after mercury exposure.

    1994-01-01

    Parathion(phosphorothioic acid O, O-diethyl O-[4-nitrophenyl] ester) is a broad spectrum organophosphorus insecticide, used on a variety of crops and occasionally for mosquito control, and is highly toxic to birds (Smith 1987). Intentional poisoning with parathion is reported to have killed more than 8000 red-winged blackbirds (Agelaius phoeniceus), common grackles (Quiscalus quiscula), brown-headed cowbirds (Molothrus ater) and European starlings (Sturnus vulgaris) in two separate instances (Stone et al. 1984). Use of parathion on wheat fields has resulted in the mortality of about 1600 Canada geese (Branta canadensis) and other waterfowl in one instance (White et al. 1982) and about 200 Canada geese in another (Flickinger et al. 1991). More than 200 laughing gulls (Larus atricilla) died near cotton fields treated with parathion (White et al. 1979). Secondary poisoning of raptors resulting from the consumption of prey exposed to parathion, has been reported experimentally and in the field. Stone et al. (1984) found two dead red-tailed hawks (Buteo jamaicensis), a Cooper's hawk (Accipiter cooperii) and an American kestrel (Falco sparverius) that had fed on blackbirds killed by parathion. One of four American kestrels died after being fed cricket frogs (Acris crepitans) that had been exposed to 10ppm parathion for 96 hr (Fleming et al. 1982). The Mississippi kite (Ictinia mississippensis) is highly insectivorous (Brown and Amadon 1968) and is thus subject to secondary poisoning resulting from consumption of insects exposed to pesticides. I report here an instance of secondary parathion poisoning in wild Mississippi kites.

    Chloracetanilide herbicides (alachlor, butachlor, metachlor) are used widely. Although there are much data about chronic low dose exposure to chloracetanilide in humans and animals, there are few data about acute chloracetanilide poisoning in humans. This study investigated the clinical feature of patients following acute oral exposure to chloracetanilide. We retrospectively reviewed the data on the patients who were admitted to two university hospitals from January 2006 to December 2010. Thirty-five patients were enrolled. Among them, 28, 5, and 2 cases of acute alachlor, metachlor, butachlor poisoning were included. The mean age was 49.8 ± 15.4 yr. The poison severity score (PSS) was 17 (48.6%), 10 (28.6%), 5 (14.3%), 2 (5.7%), and 1 (2.9%) patients with a PSS of 0, 1, 2, 3, and 4, respectively. The age was higher for the symptomatic patients (1-4 PSS) than that for the asymptomatic patients (0 PSS) (43.6 ± 15.2 vs 55.7 ± 13.5). The arterial blood HCO₃⁻ was lower in the symptomatic patients (1-4 PSS) than that in the asymptomatic patients (0 PSS). Three patients were a comatous. One patient died 24 hr after the exposure. In conclusion, although chloracetanilide poisoning is usually of low toxicity, elder patients with central nervous system symptoms should be closely monitored and cared after oral exposure.

    Conclusion: The most common drugs causing hypotension and cardiac arrhythmias were clonidine, CCBs, drotaverine and the veterinary drug “veratrine”. Drotaverine, clonidine and CCBs were the most common drugs causing death. Poisonings with these agents are rare in other countries. Measures to reduce the availability of drotaverine and veratrine should be taken in Russia.

    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.

    2007-02-01

    Poisoning from organophosphates and carbamates is a significant cause of morbidity and mortality worldwide. Concerns have been expressed over the safety and efficacy of the use of oximes such as pralidoxime (2-PAM) in patients with carbamate poisoning in general, and more so with carbaryl poisoning specifically. The goal of the present study was to evaluate the role of 2-PAM in a mouse model of lethal carbaryl poisoning. Female ICR Swiss Albino mice weighing 25-30 g were acclimated to the laboratory and housed in standard conditions. One hundred and ten mice received an LD50 dose of carbaryl subcutaneously. Ten minutes later, they were randomized by block randomization to one of eight treatment groups: normal saline control, atropine alone, 100 mg/kg 2-PAM with and without atropine, 50 mg/kg 2-PAM with and without atropine, and 25 mg/kg 2-PAM with and without atropine. All medications were given intraperitoneally and the atropine dose was constant at 4 mg/kg. The single objective endpoint was defined as survival to 24 hours. Fatalities were compared using a Chi squared or Fisher's exact test. Following an LD50 of carbaryl, 60% of the animals died. Atropine alone statistically improved survival (15% lethality). High dose 2-PAM with and without atropine was numerically worse, but not statistically different from control. While the middle dose of 2-PAM was no different than control, the addition of atropine improved survival (10% fatality). Low-dose 2-PAM statistically improved survival (25% lethality). Atropine further reduced lethality to 10%. When appropriately dosed, 2-PAM alone protects against carbaryl poisoning in mice. Failure to demonstrate this benefit in other models may be the result of oxime overdose.

  12. Accidental fatal poisoning of a dog by Dieffenbachia picta (dumb cane).

    Loretti, Alexandre Paulino; da Silva Ilha, Marcia Regina; Ribeiro, Rita Elaine Streda

    2003-10-01

    A single case of accidental fatal poisoning by Dieffenbachia picta, (dumb cane) (Araceae) in a 9-y-old female Poodle is described. Clinical signs included severe, locally extensive erosive/ulcerative glossitis accompanied by marked dyspnea of acute onset. The animal did not respond to emergency procedures to relieve severe respiratory distress; fatal asphyxiation ensued from edema of the glottis a few hours after the first clinical signs were observed. According to the owner, the dog had access to a tall, potted dumb cane plant and chewed the thick stem of the plant intensely. The owner did not authorize a necropsy of the animal. The diagnosis of Dieffenbachia picta poisoning was based on the history of accidental consumption of dumb cane and clinical signs. A comparison of this single case with other reports of dumb cane poisoning suggests that dogs poisoned by Dieffenbachia species usually recover uneventfully with conservative management and that death from asphyxiation is a rare but possible consequence of this intoxication. Severe edematous swelling of the glottis with occlusion of the larynx airway passage can occur in those cases in which large amounts of sap are quickly squeezed from the plant during intense chewing. Death would occur if owners do not seek veterinary care immediately and if emergency procedures are not instituted on time.

    To assess the evidence regarding the efficacy and safety of intravenous fat emulsion (IFE) in the management of poisoned patients. We performed a systematic review of the literature with no time or language restriction. The electronic databases were searched from their inception until June 1, 2009 (Medline, EMBASE, ISI web of science, Biological abstract, LILACS, ChemIndex, Toxnet, and Proquest). We also examined the references of identified articles and the gray literature. The target interventions eligible for inclusion were administration of any IFE before, during, or after poisoning in human or animals. All types of studies were reviewed. Eligibility for inclusion and study quality scores, based on criteria by Jadad and the STROBE statement, were evaluated by independent investigators. The primary outcome was mortality. Secondary outcomes included neurologic, hemodynamic, and electrocardiographic variables, as well as adverse effects. Of the 938 publications identified by the search strategies, 74 met the inclusion criteria. We identified 23 animal trials, 50 human, and 1 animal case reports. Overall, the quality of evidence was weak and significant heterogeneity prevented data pooling. Available data suggest some benefits of IFE in bupivacaine, verapamil, chlorpromazine, and some tricyclic antidepressants and beta-blockers toxicity. No trial assessed the safety of IFE in the treatment of acute poisoning. The evidence for the efficacy of IFE in reducing mortality and improving hemodynamic, electrocardiographic, and neurological parameters in the poisoned patients is solely based on animal studies and human case reports. The safety of IFE has not been established.

    Accidents are a daily concern in the paediatric ward because of their frequency, diversity and severity. Acute accidental poisoning (AAP) accounts for an important portion of these. To help improvement management of AAP, we conducted a retrospective study covering a period of 2 years from January 2005 to December 2006 at Charles de Gaulle Paediatric University Hospital in Ouagadougou. Of 9390 admissions during the study period, 123 children, or 1.3%, were admitted for poisoning. A cumulative average of 11 were admitted monthly, with a peak of 16 patients in April 2005 and 2006, together. AAP was most common among children aged 1 to 4 years. Their mean age was 3 years and ranged from 6 days to 12 years. Boys outnumbered girls, with a sex ratio of 1.2. Mothers of more than half (61%) of the children poisoned worked in the home. Household products accounted for 44.7% of AAPs, followed by drug (22.7%) and food (22%) poisoning. Kerosene and other petroleum products topped the list of household products, with 54.5%. Tranquilizers (46.4%) and dairy products (37%) dominated the drug and food poisoning categories. Immediate outcome was fatal in 3% of cases, and three quarters of these deaths occurred during drug poisoning of children aged 1 to 4 years. The mean hospital stay was 2 days, and ranged from 0 to 9 days. Health officials, the media, and community outreach must all help to increase awareness about the dangers of poisoning and of preventive measures.

    Created in the wake of the September 11, 2001 terrorist attacks, Maine's Office of Public Health Emergency Preparedness within the Maine Center for Disease Control and Prevention undertook a major reorganization of epidemiology and laboratory services and began developing relationships with key partners and stakeholders, and a knowledgeable and skilled public health emergency preparedness workforce. In 2003, these newly implemented initiatives were tested extensively during a mass arsenic poisoning at the Gustav Adolph Lutheran Church in the rural northern community of New Sweden, Maine. This episode serves as a prominent marker of how increased preparedness capabilities, as demonstrated by the rapid identification and administration of antidotes and effective collaborations between key partners, can contribute to the management of broader public health emergencies in rural areas.

    In November 2006, a Russian dissident died from radioactive Polonium-210 (210Po) poisoning in London. Providing reassuring messages during a public health incident may be ineffective for individuals with high health anxiety (hypochondriasis). Members of the public who called a 24-hour telephone helpline were offered a follow-up call by a health protection specialist for reassurance. A psychiatrist attempted to contact those callers who were unable to be reassured by the health protection specialist. Of 872 individuals contacted for reassurance, seven (0.6%) could not be reassured. The psychiatrist contacted four of these individuals. Three had a history of health-related anxiety and two attributed somatic symptoms to 210Po exposure. For individuals with hypochondriasis, reassurance during major public health incidents may be ineffective. Having a psychiatrist available was helpful in managing individuals with excessive health anxiety.

    Morbidity and mortality related to acute poisoning is a serious health concern worldwide. Paraquat is known to be responsible for a number of acute poisonings in south India. The study aims at presenting the various aspects of paraquat poisoning that include patient profile, clinical presentation, end-organ complications, and observations at autopsy. The present registry-based retrospective research was conducted in a tertiary care teaching hospital in south India. All the confirmed cases of paraquat poisoning were included in the present study. The postmortem and hospital records of these patients were retrieved and relevant information was collected and analyzed. Paraquat poisonings constituted 14.4% of the total poisoning fatalities during the study period. Equal number of males and females were observed in the present study. The victims were aged between 17 and 65 years (mean ± SD = 30.2 ± 13.1 years). Manner of death was suicidal in 92.9% cases. Common presenting symptoms after ingestion of paraquat included vomiting, followed by difficulty in breathing. In the present series, overall survival post paraquat consumption ranged between 10 h and 25 days. Half of the victims died within 2 days of consumption of poison. The underlying cause of death included acute renal failure (ARF), adult respiratory distress syndrome (ARDS), multiorgan failure (MOF), acute liver failure, etc., In all the cases, brain was congested and edematous, and visceral organs showed marked congestion at autopsy. Lungs were congested with marked edema in 10 cases. It is recommended that the availability of this highly toxic substance be restricted so as to prevent its misuse as a method of suicide.
