    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.

    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.

    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.

    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.

    Southern Africa is inherently rich in flora, where the habitat and climatic conditions range from arid environments to lush, sub-tropical greenery. Needless to say, with such diversity in plant life there are numerous indigenous poisonous plants, and when naturalised exotic species and toxic garden varieties are added the list of potential poisonous plants increases. The economically important poisonous plants affecting livestock and other plant poisonings of veterinary significance are briefly reviewed. In addition, a synopsis of the more common plant poisonings in humans is presented. Many of the plants mentioned in this review are also used ethnobotanically for treatment of disease in humans and animals and it is essential to be mindful of their toxic potential.

    The 9th International Symposium on Poisonous Plants (ISOPP9) was held July 15-21, 2013, at the Inner Mongolia Agricultural University in Hohhot, Inner Mongolia Autonomous Region of China. The symposium consisted of three days of oral and poster presentations, followed by a tour of the Xilinhot Region of the Mongolian Grasslands, encompassing grazing conditions consisting of desert, grassland, and steppes. This was the first time that an ISOPP meeting has been held in Asia and provided an opportunity for visitors from outside China to become aware of livestock poisonings caused by plant species with which they were previously not familiar while at the same time demonstrating that many of the problems experienced around the world have a common etiology. Presentations focused on botany, veterinary science, toxicology, mechanism of action, and chemistry. As is appropriate for the Journal of Agricultural and Food Chemistry, this cluster of papers consists of selected oral and poster presentations in which the chemistry of the toxins played a significant role. The symposium revealed that there is considerable scope for isolation, structural elucidation, and analysis of the toxins from the numerous poisonous plant species that have been identified in China. It became apparent that there are abundant opportunities for chemists both within China and abroad to collaborate with Chinese scientists working on biological aspects of livestock poisonings.

    2004-06-01

    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).

    Plant exposures are among the most frequently reported cases to poison control centres worldwide. This is a growing condition due to recent societal trends oriented towards the consumption of wild plants as food, cosmetics, or medicine. At least three general causes of plant poisoning can be identified: plant misidentification, introduction of new plant-based supplements and medicines with no controls about their safety, and the lack of regulation for the trading of herbal and phytochemical products. Moreover, an efficient screening for the occurrence of plants poisonous to humans is also desirable at the different stages of the food supply chain: from the raw material to the final transformed product. A rapid diagnosis of intoxication cases is necessary in order to provide the most reliable treatment. However, a precise taxonomic characterization of the ingested species is often challenging. In this review, we provide an overview of the emerging DNA-based tools and technologies to address the issue of poisonous plant identification. Specifically, classic DNA barcoding and its applications using High Resolution Melting (Bar-HRM) ensure high universality and rapid response respectively, whereas High Throughput Sequencing techniques (HTS) provide a complete characterization of plant residues in complex matrices. The pros and cons of each approach have been evaluated with the final aim of proposing a general user's guide to molecular identification directed to different stakeholder categories interested in the diagnostics of poisonous plants.

    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

    The plant exposures are one of the most frequent poisonings reported to poison control centres. The diagnosis of intoxicated patients is usually based on the morphological analysis of ingested plant portions; this procedure requires experience in systematic botany, because the plant identification is based on few evident traits. The objective of this research is to test DNA barcoding approach as a new universal tool to identify toxic plants univocally and rapidly. Five DNA barcode regions were evaluated: three cpDNA sequences (trnH-psbA, rpoB and matK) and two nuclear regions (At103 and sqd1). The performance of these markers was evaluated in three plant groups: (1) a large collection of angiosperms containing different toxic substances, (2) congeneric species showing different degrees of toxicity and (3) congeneric edible and poisonous plants. Based on assessments of PCR, sequence quality and resolution power in species discrimination, we recommend the combination of plastidial and nuclear markers to identify toxic plants. Concerning plastidial markers, matK and trnH-psbA showed consistent genetic variability. However, in agreement with CBOL Plant Working Group, we selected matK as the best marker, because trnH-psbA showed some problems in sequences sizes and alignments. As a final and relevant observation, we also propose the combination of matK with a nuclear marker such as At103 to distinguish toxic hybrids form parental species. In conclusion, our data support the claim that DNA barcoding is a powerful tool for poisonous plant identifications.

  2. Plant poisonings in livestock in Brazil and South Africa

    2015-03-01

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

    Full Text Available   Background. In attempt to provoke hallucinations two adolescents were poisoned with thorn apple. This plant could be easily found near urban and rural areas such as fields and dykes. It spreads around as a weed and its seeds are found even in bird’s food. In nowadays these seeds could be found in seedman’s shops offered for sale as decorative plants. While free acces to the internet enables the targeted population, in this case mostly adolescents, to gather large amount of information on hallucinogenic effects of seeds described above. It does not provide them with information on negative side effects which causes urgent visits at intensive care units of hospitals. The fact that the abuse of thorn apple’s seeds causes intoxications is more and more often described in scientific literature. In 1997/98 the paediatricians from Maribor described three cases of accidental poisoning of adolescents. In Slovenia there are only four out of twelve pediatric departments which haven’t had any case of poisoning of that kind yet.Results. Clinical data – simptoms of central and peripherial anticholinergic syndrom and the history (heteroanamnesy showed the possibility of poisoning with plant’s alkaloids with anticholinergic activity which was comfirmed by doctor on duty. She provided me in person with exact, specific and detailed description of seeds consumed by two young men. Physostigmine salicilate is the drug of choice and it is used in cases of serious poisoning.Conclusions. After serious clinical simptoms at the beginning both adolescents recovered well and after three days of medical supervision they were released from the hospital without any consequences harmful to their health.

    2015-12-08

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

    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.

    Given the variety of existing plant species in the environment, it is remarkable that people have adjusted as well as they have to the many plants that can cause uncomfortable skin reactions. With a basic understanding of the types of reaction and the common plants that cause each type, physicians can help patients discover the source of the dermatitis and thus prevent reexposure. In immediate contact dermatitis, welts form rapidly after patients brush against an offending plant, but the urticarial rash is short-lived. In irritant contact dermatitis, the skin is traumatized mechanically (eg, with cactus spines) or chemically (eg, with capsaicin from hot peppers), producing a more persistent skin reaction. Phytophotodermatitis occurs when the skin is exposed to sunlight after contact with an offending plant; reactions are erythema, pruritus, vesiculation, and subsequent hyperpigmentation. Allergic contact dermatitis, typified by the rash of poison ivy, is a cell-mediated immune response that occurs in previously sensitized persons. Erythema, vesiculation, and pruritus, which usually heal without causing pigmentary changes, may last for several weeks.

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

    A relationship between sensitivity to poison oak or poison ivy and mango dermatitis has been suggested by previous publications. The observation that acute allergic contact dermatitis can arise on first exposure to mango in patients who have been sensitized beforehand by contact with other urushiol-containing plants has been documented previously. We report 17 American patients employed in mango picking at a summer camp in Israel, who developed a rash of varying severity. All patients were either in contact with poison ivy/oak in the past or lived in areas where these plants are endemic. None recalled previous contact with mango. In contrast, none of their Israeli companions who had never been exposed to poison ivy/oak developed mango dermatitis. These observations suggest that individuals with known history of poison ivy/oak allergy, or those residing in area where these plants are common, may develop allergic contact dermatitis from mango on first exposure. We hypothesize that previous oral exposure to urushiol in the local Israeli population might establish immune tolerance to these plants.

    Data from the American Association of Poison Control Centers (AAPCC) and the Cincinnati-based Drug and Poison Information Center (DPIC) were analyzed to determine the incidence and trends of human plant poisonings since the year 2000. Approximately 3.4% of the approximately 4.3 million annual calls to the AAPCC centers involved plants, with a higher fraction (4.5%) for pediatric exposures. Nearly 70% of plant exposures occurred in children under six. Only 8% of cases required treatment in a health-care facility, and only 0.1% (in 2008) were considered severe outcomes. The most prominent groups of plants involved in exposures are those containing oxalates, and the most common symptom is gastroenteritis. The top 12 identified plants (in descending order) nationally were Spathiphyllum species (peace lilly), Philodendron species (philodendron), Euphorbia pulcherrima (poinssettia), Ilex species (holly), Phytolacca americana (pokeweed), Toxicodendron radicans (poison ivy), Capsicum (pepper), Ficus (rubber tree, weeping fig), Crassula argentea (jade plant), Diffenbachia (dumb cane), Epipremnum areum (pothos) and Schlumbergera bridesii (Christmas cactus). Broad overlaps between the DPIC and the AAPCC incidence data were noted, with essentially the same plant species in each dataset. The nature of the various toxins, the symptomatology and potential treatments are discussed for the highest ranking plant species. Copyright © 2011 Elsevier Inc. All rights reserved.

    ObjectivePoisonous plants are a deadly threat to public health in China. The traditional clinical diagnosis of the toxic plants isinefficient, fallible, and dependent upon experts. In this study, we tested the performance of DNA barcodes for identification of the most threatening poisonous plants in China. MethodsSeventy-four accessions of 27 toxic plant species in 22 genera and 17 families were sampled andthree DNA barcodes (matK,rbcL, and ITS) were amplified, sequenced and tested.Three methods, Blast,pairwise global alignment (PWG)distance, and Tree-Building were tested for discrimination power. ResultsThe primer universality of all the three markers was high. Except in the case of ITS for Hemerocallisminor, the three barcodes were successfully generated from all the selected species. Among the three methodsapplied, Blast showed the lowest discrimination rate,whereasPWGDistance and Tree-Building methods were equally effective. The ITS barcode showed highest discrimination rates using the PWG Distance and Tree-Building methods. When the barcodes were combined, discrimination rates were increased for the Blast method. ConclusionDNA barcoding technique provides us a fast tool for clinical identification of poisonous plants in China.We suggestmatK,rbcL, ITS used in combination as DNA barcodes for authentication of poisonous plants.

Also known as prussic acid, it has killed countless humans throughout history in accidents and during the Holocaust. Hydrogen cyanide is also used by plants to defend themselves against insects and other herbivorous animals. Many plants produce chemicals called cyanogenic glycosides that can be converted into hydrogen cyanide when the plant is eaten. This is an ancient and efficient defense against all sorts of h...

    In recent years recorded cases of plant poisoning have become rare, this may in part be due to the possibility of plant ingestion not being indicated at the beginning of an investigation. Aconitum napellus (aconite, Wolfsbane, Monkshood) is one of the most poisonous plants in the UK. It contains various potent alkaloids such as aconitine, isoaconitine, lycaconitine and napelline. Ingestion of Aconitum plant extracts can result in severe, potentially fatal toxic effects. This paper describes the analytical findings in a recent death in the UK. resulting from deliberate ingestion of Aconitum napellus extract. The concentrations of aconitine measured by HPLC-DAD in the post mortem femoral blood and urine were 10.8 micrograms/L and 264 micrograms/L, respectively. The aconitine concentration in the ante mortem urine was 334 micrograms/L and was estimated to be 6 micrograms/L in the ante mortem serum. Hence, accidental, suicidal or homicidal poisoning due to the ingestion of plant material remains a possibility and should be borne in mind when investigating sudden or unexplained death.

    Quinolizidine and piperidine alkaloid teratogens from Lupinus, Conium, and Nicotiana genera have been identified as causes of birth defects in livestock induced by poisonous plants. Many defects now known to be related to poisonous plant ingestion were once thought to have a genetic origin. This supposition delayed diagnosis, reporting, and understanding of such birth defects, because breeders and producers feared the news would make it difficult to sell breeding stock. Defects caused by quinolizidine and piperidine teratogens include cleft palate and contracture-type skeletal defects such as arthrogryposis, scoliosis, torticollis, and kyphosis. Teratogens have been identified, differences in susceptibility to teratogenic compounds among livestock species have been elucidated, periods of gestation when specific types of birth defects occur have been determined, and information about mechanism of action has been developed.

    Practically all human populations are environmentally exposed to cadmium (Cd), mostly through plant-derived food. A growing body of epidemiological evidence suggests that there is no margin of safety between current Cd exposure levels and the threshold for adverse health effects and, hence, there is an urgent need to lower human Cd intake. Here we review recent studies on rice (Oryza sativa) and Cd-hyperaccumulating plants that have led to important insights into the processes controlling the passage of Cd from the soil to edible plant organs. The emerging molecular understanding of Cd uptake, root retention, root-to-shoot translocation and grain loading will enable the development of low Cd-accumulating crops.

    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.

  11. Chronic cadmium poisoning in a pigment manufacturing plant

    De Silva, P.E.; Donnan, M.B.

    1981-02-01

    When the working environment in a small cadmium-pigment manufacturing plant was investigated, cadmium concentrations in respirable dust were found to be considerably above the hygiene standard recommended by the British Occupational Hygiene Society. Cadmium concentrations in blood and urine of exposed workers, both present and past employees, were determined. The six men who had worked in the production plant for seven years or more all showed signs of renal tubular damage. On the basis of the results of the investigations on individuals in this study, it is suggested that urinary cadmium concentrations should be kept below 15 microgram/day to avoid the possibility of renal damage, and that the insoluble respirable fraction of cadmium dust should not be regarded as merely nuisance dust.

    The present investigation was carried out to evaluate the toxic effects of traditional Ethiopian fish poisoning plant Birbira [vernacular name (local native language, Amharic); Milletia ferruginea] seed extract on aquatic macroinvertebrates, Baetidae (Mayflies) and Hydropsychidae (Caddisflies), under laboratory conditions. In Ethiopia, toxic plant; Milletia ferruginea pulverized seeds have been used for fish poisoning since time immemorial. Macroinvertebrates are important biological indicators of alteration in the natural water sources. Milletia ferruginea seed extract was applied at concentrations of 125, 250, 500 1000 and 2000 ppm on Hydropsychididae whereas Baetidae were exposed at various concentrations viz., 31.25, 62.5, 125, 250 & 500 ppm. Milletia ferruginea seeds crude extract of lethal doses (LCso and LC90) required for Baetidae 49.29 mg/l and 172.52 mg/l were respectively and the respective doses (LC50 and LC90) against Hydropsychidae were 679.64 mg/l and 2383.93 mg/l. The present investigation end result demonstrated that Milletia ferruginea seed extracts were extremely toxic to Baetidae than Hydropsychididae. As a result, application of Milletia ferruginea seed extracts into the rivers/streams for fish poisoning possibly leads to contamination and disruption of food chain in the aquatic ecosystem. Therefore, the concerned authorities should launch appropriate awareness campaign among the local inhabitants and fisherman about adverse effect of Birbira seed extracts. Furthermore, providing alternative ecofriendly techniques for fish harvesting may possibly bring constructive out come in the near future.

    Plant food supplements (PFS) are products of increasing popularity and wide-spread distribution. Nevertheless, information about their risks is limited. To fill this gap, a poisons centres-based study was performed as part of the EU project PlantLIBRA. Multicentre retrospective review of data from selected European and Brazilian poisons centres, involving human cases of adverse effects due to plants consumed as food or as ingredients of food supplements recorded between 2006 and 2010. Ten poisons centres provided a total of 75 cases. In 57 cases (76%) a PFS was involved; in 18 (24%) a plant was ingested as food. The 10 most frequently reported plants were Valeriana officinalis, Camellia sinensis, Paullinia cupana, Melissa officinalis, Passiflora incarnata, Mentha piperita, Glycyrrhiza glabra, Ilex paraguariensis, Panax ginseng, and Citrus aurantium. The most frequently observed clinical effects were neurotoxicity and gastro-intestinal symptoms. Most cases showed a benign clinical course; however, five cases were severe. PFS-related adverse effects seem to be relatively infrequent issues for poisons centres. Most cases showed mild symptoms. Nevertheless, the occurrence of some severe adverse effects and the increasing popularity of PFS require continuous active surveillance, and further research is warranted.

    An adult man entered an oil separator room to remove waste oil from a vacuum pump in a geothermal power plant. He suddenly collapsed and died soon after. Since hydrogen sulfide gas was detected in the atmosphere at the scene of the accident, poisoning by this gas was suspected and toxicological analysis of sulfide and thiosulfate in blood, brain, lung, femoral muscle was made using the extractive alkylation technique combined with gas chromatography/mass spectrometry (GC/MS). The concentrations of sulfide in these tissues were similar to those previously reported for fatal cases of hydrogen sulfide gas. The concentration of thiosulfate in the blood was at least 48 times higher than the level in control samples. Based on these results, the cause of death was attributed to hydrogen sulfide gas poisoning.

    Plant intoxications in wildlife are difficult to diagnose, are overlooked, or are sometimes even neglected. Hence, factors that induce wild animals to ingest poisonous plants have not been sufficiently documented. An outbreak of glycoprotein storage disease in sambar deer ( Cervus unicolor ), induced by ingestion of the swainsonine-containing plant, common wireweed (Sida carpinifolia), is reported. Nine out of 55 deer held by a zoo in Brazil were affected. The poisoning was characterized by emaciation and neurologic signs followed by unexpected death in some of the animals. Animals presented abnormal consciousness, posterior paresis, and musculoskeletal weakness; less evident were vestibulo-cerebellar signs. Histologically, there was vacuolation of neurons and epithelial cells of the pancreatic acines, thyroid follicules, and renal tubules. Furthermore, in the central nervous system were axonal degeneration, necrosis, and loss of neurons. Three factors may lead to the ingestion of S. carpinifolia by sambar deer: 1) A grazing field with only S. carpinifolia as a source of forage; 2) a large number of animals kept in this field; and 3) a hierarchy within a cervid group in which dominant males isolated and displaced juvenile and weaker adult males, leaving them with access to only S. carpinifolia.

    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.

    Scorpions, especially in urban areas of tropical and subtropical regions, present a common risk of poisoning. In Mexico, scorpion envenomation is considered a public health problem. Despite the frequency of scorpion sting cases, there are to date no uniform criteria for their treatment. In Mexican traditional medicine, different plant species have been widely used as a remedy for treating scorpion poisoning. The aim of this work was to evaluate the effect of Bouvardia ternifolia, Aristolochia elegans and Vitex mollis extracts on Centruroides limpidus limpidus venom lethality in mice, and to determine their antagonist activity on guinea pig ileum. The hexane and methanol extract from B. ternifolia modified the LD50 of C. limpidus limpidus venom from 0.750 +/- 0.08 to 1.64 +/- 0.19 and 1.16 +/- 0.14 mg/kg, respectively. The extracts of A. elegans produced lower antitoxic activity, while extracts of V. mollis did not show any protection. On in vitro test, addition of B. ternifolia and A. elegans extracts strongly inhibited, in a concentration-dependent manner, the ileum contractions induced by venom. In general, the results demonstrated the effectiveness of these two plant species in modifying the lethality of C. limpidus limpidus venom in mice.

    Cardioactive steroids (CASs) are found in plants, animals, and insects. Their affinity for Na+-K+ ATPase is attenuated by the type of lactone at carbon 17 (C17) of the steroid backbone: those with 5-membered lactone rings, or cardenolides, are derived mostly from plants with 6-membered rings or from animals with bufadienolides. A systematic review of CAS poisoning was performed to compare the mortality rate of cardenolides and bufadienolides. MEDLINE was searched for articles using commonly reported names of CASs, and keywords were limited to human cases only. We searched cases from 1982 to 2003, so that supportive care was similar and digoxin-specific Fab was available. Identified reports of CAS poisoning were read to exclude cases involving licensed pharmaceuticals. Inclusion criteria included hyperkalemia, gastrointestinal symptoms, electrocardiographic evidence of CAS toxicity, digoxin serum concentration, or history of exposure to a substance containing a CAS. Clinical data was collected, including information about treatment with digoxin-specific Fab and treatment outcome. Fifty-nine articles, describing 924 patients, were identified. Eight hundred ninety-seven patients (97%) ingested a CAS with a 5-membered lactone ring, and mortality was 6% (n = 54). Twenty-seven patients (2.9%) ingested a CAS with a 6-membered lactone ring, and mortality was 29.6% (n = 8). The difference in mortality rates was statistically significant (p < 0.001, [X2]). CASs with 6-member rings accounted for the highest percentage of nonsuicidal exposures. Although cardenolides accounted for the majority of exposures, bufadienolides were five times more lethal than cardenolides.

    The diagnosis of lead poisoning in horses living on farmland in the vicinity of a battery recycling plant was based on clinical signs as well as on laboratory findings. Chemical analysis of six surface soils (0-15 cm) and herbage samples taken at different distances to the recycling plant showed very high total lead levels in the closest sites to the facility and a clear decrease with distance. Total lead levels in soil samples ranged from 127 to 5657 mg kg{sup -1}, with more than 70% of lead extractable by EDTA in the most polluted soils. Lead levels in the aerial part of herbage samples were in the range of 113-4741 mg kg{sup -1}. A water washing pre-treatment of the vegetal samples considerably diminished the concentration of lead, suggesting that airborne lead particles from the facility emissions were fixed on the shoots. The analysis of samples taken from six dead horses showed lead concentrations, expressed as mg kg{sup -1} (d.w.), as follows: blood: 0.20-0.89; liver: 2.5-15; kidney: 1.70-6.75. Lead intake levels, estimated according to the ingestion rate of Grammineae forage, illustrates that the apported lead through the ingestion of vegetation growing in the closest sites to the recycling plant was approximately 99.5 mg Pb/kg body weight/day surpassing the fatal dosage for horses of 2.4 mg Pb/kg body weight/day reported by Hammond and Aronson, Ann NY Acad Sci, 1964; 111: 595-611.

    Ayurveda involves the use of drugs obtained from plants, animals, and mineral origin. All the three sources of drugs can be divided under poisonous and nonpoisonous category. There are various crude drugs, which generally possess unwanted impurities and toxic substances, which can lead to harmful health problems. Many authors have reported that not all medicinal plants are safe to use since they can bear many toxic and harmful phytoconstituents in them. Śodhana (detoxification/purification) is the process, which involves the conversion of any poisonous drug into beneficial, nonpoisonous/nontoxic ones. Vatsanābha (Aconitum species), Semecarpus anacardium, Strychnos nux-vomica, Acorus calamus, Abrus precatorius etc., are some of the interesting examples of toxic plants, which are still used in the Indian system of medicine. Aconite, bhilawanols, strychnine, β-asarone, abrin are some of the toxic components present in these plants and are relatively toxic in nature. Śodhana process involves the purification as well as reduction in the levels of toxic principles which sometimes results in an enhanced therapeutic efficacy.

    Full Text Available Ayurveda involves the use of drugs obtained from plants, animals, and mineral origin. All the three sources of drugs can be divided under poisonous and nonpoisonous category. There are various crude drugs, which generally possess unwanted impurities and toxic substances, which can lead to harmful health problems. Many authors have reported that not all medicinal plants are safe to use since they can bear many toxic and harmful phytoconstituents in them. Śodhana (detoxification/purification is the process, which involves the conversion of any poisonous drug into beneficial, nonpoisonous/nontoxic ones. Vatsanābha (Aconitum species, Semecarpus anacardium, Strychnos nux-vomica, Acorus calamus, Abrus precatorius etc., are some of the interesting examples of toxic plants, which are still used in the Indian system of medicine. Aconite, bhilawanols, strychnine, β-asarone, abrin are some of the toxic components present in these plants and are relatively toxic in nature. Śodhana process involves the purification as well as reduction in the levels of toxic principles which sometimes results in an enhanced therapeutic efficacy. The present review is designed to extensively discuss and understand the scientific basis of the alternative use of toxic plants as a medicine after their purification process.

    The use of archery to hunt appears relatively late in human history. It is poorly understood but the application of poisons to arrows to increase lethality must have occurred shortly after developing bow hunting methods; these early multi-stage transitions represent cognitive shifts in human evolution. This paper is a synthesis of widely-scattered literature in anthropology, entomology, and chemistry, dealing with San ("Bushmen") arrow poisons. The term San (or Khoisan) covers many indigenous groups using so-called 'click languages' in southern Africa. Beetles are used for arrow poison by at least eight San groups and one non-San group. Fieldwork and interviews with Ju|'hoan and Hai||om hunters in Namibia revealed major differences in the nature and preparation of arrow poisons, bow and arrow construction, and poison antidote. Ju|'hoan hunters use leaf-beetle larvae of Diamphidia Gerstaecker and Polyclada Chevrolat (Chrysomelidae: Galerucinae: Alticini) collected from soil around the host plants Commiphora africana (A. Rich.) Engl. and Commiphora angolensis Engl. (Burseracaeae). In the Nyae Nyae area of Namibia, Ju|'hoan hunters use larvae of Diamphidia nigroornata Ståhl. Larvae and adults live above-ground on the plants and eat leaves, but the San collect the underground cocoons to extract the mature larvae. Larval hemolymph is mixed with saliva and applied to arrows. Hai||om hunters boil the milky plant sap of Adenium bohemianum Schinz (Apocynaceae) to reduce it to a thick paste that is applied to their arrows. The socio-cultural, historical, and ecological contexts of the various San groups may determine differences in the sources and preparation of poisons, bow and arrow technology, hunting behaviors, poison potency, and perhaps antidotes.

    Datura stramonium is a widely used poisonous plant with great medicinal and economic value. Its chloroplast (cp) genome is 155,871 bp in length with a typical quadripartite structure of the large (LSC, 86,302 bp) and small (SSC, 18,367 bp) single-copy regions, separated by a pair of inverted repeats (IRs, 25,601 bp). The genome contains 113 unique genes, including 80 protein-coding genes, 29 tRNAs and four rRNAs. A total of 11 forward, 9 palindromic and 13 tandem repeats were detected in the D. stramonium cp genome. Most simple sequence repeats (SSR) are AT-rich and are less abundant in coding regions than in non-coding regions. Both SSRs and GC content were unevenly distributed in the entire cp genome. All preferred synonymous codons were found to use A/T ending codons. The difference in GC contents of entire genomes and of the three-codon positions suggests that the D. stramonium cp genome might possess different genomic organization, in part due to different mutational pressures. The five most divergent coding regions and four non-coding regions (trnH-psbA, rps4-trnS, ndhD-ccsA, and ndhI-ndhG) were identified using whole plastome alignment, which can be used to develop molecular markers for phylogenetics and barcoding studies within the Solanaceae. Phylogenetic analysis based on 68 protein-coding genes supported Datura as a sister to Solanum. This study provides valuable information for phylogenetic and cp genetic engineering studies of this poisonous and medicinal plant.

    The currative properties of aromatic and medicinal plants have been recognized since ancient times and, more recently, the antimicrobial activity of plant essential oils has been used in several applications, including food preservation. The purpose of this study was to create directly comparable, quantitative data on the antimicrobial activity of some plant essential oils prepared in the National Institute of Research-Development for Chemistry and Petrochemistry, Bucharest to be used for the further development of food packaging technology, based on their antibacterial and antifungal activity. The essential oils extracted from thyme (Thymus vulgaris L.), basil (Ocimum basilicum L.), coriander (Coriandrum sativum L.), rosemary (Rosmarinus officinalis L.), sage (Salvia officinalis L.), fennel (Foeniculum vulgare L.), spearmint (Mentha spicata L.) and carraway (Carum carvi L.) were investigated for their antimicrobial activity against eleven different bacterial and three fungal strains belonging to species reported to be involved in food poisoning and/or food decay: S. aureus ATCC 25923, S. aureus ATCC 6538, S. aureus ATCC 25913, E. coli ATCC 25922, E. coli ATCC 35218, Salmonella enterica serovar Enteritidis Cantacuzino Institute Culture Collection (CICC) 10878, Listeria monocytogenes ATCC 19112, Bacillus cereus CIP 5127, Bacillus cereus ATCC 11778, Candida albicans ATCC 10231, Aspergillus niger ATCC 16404, Penicillium spp. CICC 251 and two E. coli and Salmonella enterica serovar Enteritidis clinical isolates. The majority of the tested essential oils exibited considerable inhibitory capacity against all the organisms tested, as supported by growth inhibition zone diameters, MICs and MBC's. Thyme, coriander and basil oils proved the best antibacterial activity, while thyme and spearmint oils better inhibited the fungal species.

    2012-04-01

    The objective of this review is to provide a report on toxic plants causing reproductive problems in ruminants in Brazil. Aspidosperma pyrifolium causes abortion or stillbirth in goats, as well as most likely in sheep and cattle, in the semiarid regions of Northeastern Brazil. Intoxications by Ateleia glazioveana, Tetrapterys acutifolia and T. multiglandulosa result in abortion and neonatal mortality in cattle and sheep, and the same signs have been experimentally observed in goats. These three plants can also cause cardiac fibrosis and a nervous disease with spongiosis of the central nervous system. Other plants known to cause abortion include Enterolobium contortisiliquum, E. gummiferum, Stryphnodendron coriaceum, S. obovatum and S. fissuratum. These plants can also cause digestive signs and photosensitization. Abortions have been reported in animals intoxicated by nitrates and nitrites as well. Infertility, abortions and the birth of weak offspring have been reported in animals intoxicated by plants containing swainsonine, including Ipomoea spp., Turbina cordata and Sida carpinifolia. Trifolium subterraneum causes estrogenism in cattle. Mimosa tenuiflora and, most likely, M. ophthalmocentra cause malformations and embryonic mortality in goats, sheep and cattle in the semiarid regions of Northeastern Brazil.

The major difficult points and problems for the implementation of morphological identification are: lack of accreditation organizations, methods and standards; no residual poisoning food remained or the morphology of food being damaged after processing; the value of identifying ordinary commercial poisonous animal and plant food and eating common poisonous animal and plant food by mistake is small;morphological identification of processed animal and plant food was difficult; the same type of toxic components have different biological problems. For this reason, a more completed set of diagnostic criteria was proposed: morphological identification should be taken as supplementary diagnostic criteria;the scope of laboratory diagnosis should be extended; a general statement on diagnostic criteria was proposed. Suggestions of setting a national directory on poisonous animal and plant foods, and strengthening the study on laboratory diagnostic indicators and test methods for toxins and other biological samples

    In successive years, three members of the same family (a man and woman aged 46 years and their son, aged 20) constantly developed severe pruritic, erythematous, vesicular and bullous dermatitis in the spring and summer after working in the garden. Although the findings were consistent with a photophytotoxic dermatitis, the causative plant remained unclear. Oral therapy with high doses ofprednisolone was necessary. When the man travelled to the USA and visited a doctor there, he recognised the symptoms as those of contact dermatitis caused by poison ivy (Toxicodendron radicans), a plant that is found sporadically in the wild state in Europe. Their grandparents had brought the plant back from a trip to the USA and planted it in the garden because of the beautiful fall colours. The family identified the plant via a search on Internet and eliminated it from the garden completely. Since then, the family has no longer suffered from contact-allergy dermatitis.

  7. Dying Hunters, Poison Plants, and Mute Slaves-Nature and Tradition in Contemporary Nuosu Yi Poetry

    Directory of Open Access Journals (Sweden)

    2009-03-01

    Full Text Available Themes of nature and traditional culture are common in the works of ethnic poets from a subgroup of the large Yi ethnic group of southwest China known as the Nuosu. Nuosu culture is synonymous with the Liangshan Mountains of southern Sichuan Province. Since the 1980s several dozen Nuosu poets have emerged to form what can be called the 'Liangshan School' of contemporary Chinese poetry. Drawing on theory from Ethnopoetics, Ecoliterature, and Folkloristics the paper introduces major themes in the works of these Nuosu poets and introduces poems by three poets who distinctly utilize nature imagery from a common pool of Yi cultural traditions. These traditions include oral literature, ritual, folk costume, and traditional ideas about social hierarchy and gender relations. Much of the nature imagery is related to folk knowledge of native animals and plants. A major theme in the poetry is the response to changes in tradition and the local environment brought about by rapid growth and development in China.

    Full Text Available ABSTRACT: Amorimiapubiflora (Malpighiaceae, which contains sodium monofluoroacetate (MFA is the main cause of "sudden death" in cattle in the Brazilian state of Mato Grosso. This research investigated the induction of resistance to the poisoning in sheep by the continuous administration of non-toxic doses of the plant and also the possibility to transfer this resistance to other sheep by the transfaunation of ruminal fluid. For this a group of four sheep (G1 received daily doses of 0.5g kg-1 for 20 days and after an interval of 15 days were challenged with three daily doses of 1g kg-1 for 3 days. Also the transfer of resistance to A. pubiflora poisoning was evaluated by transfaunation of rumen fluid (100ml for 10 days from G1 sheep to five sheep (G2, followed by challenge with the dose of 1g kg-1 for 3 days (G2D2 and after a three-day interval they received a single dose of 3g kg-1 (G2D3. The degree of resistance was evaluated by monitoring the onset of clinical signs, heart rate, and outcome of the poisoning compared with the control groups, which were challenged with three daily doses of 1g kg1 (G3 and with a single dose of 3g kg-1 (G4. Clinical parameters evaluated in Groups G1 and G2 were significantly less pronounced than those observed in G3 and G4 (control (P<0.05. Sheep in G4 (control died after receiving a single dose of 3g kg-1, while those in G2 (transfaunated survived. These findings demonstrated that consumption of non-toxic doses of A. pubiflora induced resistance in sheep and that this resistance can be transferred by transfaunation. New experiments are needed to determine the most efficient ways to induce resistance and to use this technique in the field to prevent the poisoning.

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

    Science.gov (United States)

    Ogada, Darcy L

    2014-08-01

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

  6. Marijuana poisoning.

    2013-02-01

    The plant Cannabis sativa has been used for centuries for the effects of its psychoactive resins. The term "marijuana" typically refers to tobacco-like preparations of the leaves and flowers. The plant contains more than 400 chemicals but the cannabinoid δ-9-tetrahydrocannabinol (THC) is the major psychoactive constituent. "Hashish" is the resin extracted from the tops of flowering plants and generally has a much higher THC concentration. Marijuana is the most commonly used illicit drug in the United States. Currently, several states have passed legislation to decriminalize possession of small amounts of marijuana for both medical and personal use and several other states have similar legislation under consideration. The most common form of marijuana use in humans is inhalation of the smoke of marijuana cigarettes, followed by ingestion. In animals, although secondhand smoke inhalation is possible, the most common source of exposure is through ingestion of the owner's marijuana supply. The minimum lethal oral dose for dogs for THC is more than 3 g/kg. Although the drug has a high margin of safety, deaths have been seen after ingestion of food products containing the more concentrated medical-grade THC butter. There are two specific cannabinoid receptors in humans and dogs, CB1 (primarily in central nervous system) and CB2 (peripheral tissues). In animals, following oral ingestion, clinical effects begin within 60 minutes. All of the neuropharmacologic mechanisms by which cannabinoids produce psychoactive effects have not been identified. However, CB1 activity is believed to be responsible for the majority of cannabinoid clinical effects. Highly lipid soluble, THC is distributed in fat, liver, brain, and renal tissue. Fifteen percent of THC is excreted into the urine and the rest is eliminated in the feces through biliary excretion. Clinical signs of canine intoxication include depression, hypersalivation, mydriasis, hypermetria, vomiting, urinary incontinence

    poisoning is that the animals that eat these plants develop the habit of eating them compulsively and, by social facilitation, induce other animals of the same species to eat them. Clinical signs of the poisoning are rough hair coat, weight loss, and nervous signs associated mainly with cerebellar and brain stem lesions. Weight losses or decreased weight gains still occurring also in animals with chronic clinical signs removed from the areas where the plants occur. Reproductive losses are also reported. Chronically affected animals, also without still ingesting the plant, are more susceptible to gastrointestinal parasites. Cerebellar atrophy has been observed grossly in chronic cases. Main histologic lesions are vacuolation of neurons, epithelial cells of the pancreas and kidney, thyroid follicular cells, hepatocytes, and macrophages of lymphoid organs. To control the poisoning animals must be removed immediately from the areas invaded by the plant. The only preventive measure to prevent the ingestion of the plant is their elimination from invaded areas or through conditioned food aversion.

    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.

    Two experiments, each with 10 pregnant ewes (8 treated and 2 controls) were performed to determine if nursing lambs of lactating ewes become intoxicated when the ewes ingest Ipomoea asarifolia but do not show clinical signs themselves. In the first experiment the sheep grazed I. asarifolia in the field while in the second, sheep were maintained in individual bays consuming dry I. asarifolia at 10% and 20% into their ration. In both experiments the lambs remained confined, consuming only their mother's milk. Four of 8 lambs in the grazing experiment and the 4 nursing lambs from the ewes given 20% I. asarifolia showed signs of I. asarifolia poisoning. These results confirm that the tremorgenic compound of I. asarifolia or its toxic metabolites are eliminated in milk and can intoxicate nursing lambs.

    2011-07-01

    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.

  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.

    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.

    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.

    In order to verify effects of different grassland vegetation restorations on species composition, diversity and biomass of poisonous plants in alpine meadow, the sample plots of natural grassland were imposed with sward ripping, reseeding, fertilization and integrated treatments. The results showed that there were significant differences in species compositions and proportions of poisonous plants in different sample plots (P〈0.05). Compared with the control, the species number and Shannon-Wiener index of poisonous plants in the communities were reduced significantly by treatments of reseeding, sward ripping and fertilization (P〈0.05). The order of species number and Shannon-Wiener index of poisonous plants in different sample plots was reseeding〈fertilization=integrated treatments sward ripping 〈 control and rcseeding〈sward ripping〈fertilization〈control〈integrated treatments, respectively. At the same time, reseeding, fertilization and integrated treatments reduced the aboveground biomass of poisonous plants effectively (P〈0.05), but the sward ripping increased their aboveground biomass (P〉0.05). The order of aboveground biomass of poisonous plants was reseeding 〈 integrated treatments 〈 fertilization control〈ward ripping. In the reseeding plots, Elymus nutans became a single dominant community so that the species number, diversity index and aboveground biomass of poisonous plants were dropped to the lowest points. Thus, to improve the degraded grassland of noxious and miscellaneous grass type, reseeding is regarded as one of the optimal measures for grassland restoration.%通过对高寒草甸天然草地实施划破、补播、施肥及综合处理,探讨了不同草地植被恢复措施对高寒草甸有毒植物物种组成、多样性及生物量的影响。结果表明,不同处理草地中,有毒植物的组成及比例差异显著(P〈0.05)。与对照相比,补播、划破和施肥均不同程度地降低了群落

    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.

    2003-12-17

    There is natural intoxication of livestock by the ingestion of Ipomoea carnea (Convolvulaceae) in Brazil and other parts of the world. The alkaloidal glycosidase inhibitors swainsonine, 2-epi-lentiginosine, and calystegines B(1), B(2), B(3), and C(1) have been identified as constituents of this plant. Swainsonine is a potent inhibitor of rat lysosomal alpha-mannosidase, with an IC(50) value of 0.02 microM, whereas calystegines B(1), B(2), and C(1) are potent inhibitors of rat lysosomal beta-glucosidase, with IC(50) values of 2.1, 0.75, and 0.84 microM, respectively. The action of swainsonine results in a lysosomal storage disorder that closely mimics alpha-mannosidosis in humans. To determine whether the toxicity of I. carnea to livestock is due to purely swainsonine or due to a combination of effects by swainsonine and calystegines, intracellular lysosomal glycosidase activities in normal human lymphoblasts grown with inhibitors in the medium were examined. Incubation of lymphoblasts with 0.1 microM swainsonine for 3 days resulted in approximately 60% reduction of alpha-mannosidase activity. On the other hand, calystegines B(2) and C(1) showed no inhibition of beta-glucosidase up to 1 mM; instead inclusion of calystegines B(2) and C(1) at 100 microM in the culture medium increased its activity by 1.5- and 1.6-fold, respectively. Calystegines B(2) and C(1) seem to act as chemical chaperones, enhancing correct folding of the enzyme and enabling smooth trafficking to the lysosome. The lysosomal beta-glucosidase inhibitory calystegines seem to have little risk of inducing intoxication of livestock.

    Poison ivy causes more allergic contact dermatitis (ACD) than any other cause. Although physicians rightfully focus on the treatment of the dermatitis, prevention will be aided by recognition of the foreboding plant. Likewise, many other plants can masquerade as poison ivy and cause one to needlessly curtail his or her activities because of fear of a bad reaction. The most common poison ivy pretenders in the United States are discussed, and distinguishing plant characteristics are highlighted.

    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.

    Two people out of three who accidentally ate boiled aconite leaves died in 2012. This was a typical case of aconite poisoning in Japan: Aconite (Aconitum spp.) was mistakenly collected instead of Anemone flaccida, an edible wild plant. The leaves of these plants are quite similar to each other. Chemical analyses of the aconite plant left at the scene suggested intake of a fatal amount of aconitine alkaloids by each person. The collector, who died, had missed the botanical differences between the two plants, even though he owned a wild plant guidebook. A. flaccida should be collected with its flowers in order to aid positive indentification and avoid aconite poisoning.

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

    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.

    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.

  14. 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

    The poisoning information database (PIDB) provides clinical toxicological information on commonly encountered toxic substances in Korea. The aim of this study was to estimate the coverage rate of the PIDB by comparing the database with the distribution of toxic substances that real poisoning patients presented to 20 emergency departments. Development of the PIDB started in 2007, and the number of toxic substances increased annually from 50 to 470 substances in 2014. We retrospectively reviewed the medical records of patients with toxic exposure who visited 20 emergency departments in Korea from January to December 2013. Identified toxic substances were classified as prescription drug, agricultural chemical, household product, animal or plant, herbal drug, or other. We calculated the coverage rate of the PIDB for both the number of poisoning cases and the kinds of toxic substances. A total of 10,887 cases of intoxication among 8,145 patients was collected. The 470 substances registered in the PIDB covered 89.3% of 8,891 identified cases related to poisoning, while the same substances only covered 45.3% of the 671 kinds of identified toxic substances. According to category, 211 prescription drugs, 58 agricultural chemicals, 28 household products, and 32 animals or plants were not covered by the PIDB. This study suggested that the PIDB covered a large proportion of real poisoning cases in Korea. However, the database should be continuously extended to provide information for even rare toxic substances.

    Objective To investigate the'incidence of occupational chronic cadmium poisoning in cadmium battery plants and the correlation between working age and the three key diagnosis indicators, including urinary cadmium, urinary retinol binding protein and urinary β2 microglobulin, and to provide the scientific evidence for prevention and control of cadmium poisoning. Methods Forty- five cases diagnosed with cadmium poisoning were served as the study objects, and the diagnosis data were collected for comprehensive analysis by vocational health care investigation, risk factors in site detection and vocational health examination. Results The concentration of cadmium in workplace air was 0.001 ~0.848 mg/m3, which was higher than that of the requirement of "Operational Site Harm Factor Occupation Contact Limiting Value" (GBZ2.1 - 2007). Among the 45 cases, RBP was linearly correlated with β2MG content, while urinary cadmium, RBP and β2MG were not linearly correlated with working age. The incidence of accompanying kidney stone was higher in those poisoning cases. Conclusions RBP has greater diagnostic significance for patients with occupational chronic cadmium poisoning, but the diagnostic value of β2MG is subject to decline. It is necessary to strengthen the control of occupational cadmium hazards and control occupational hazards at its sources by replacing cadmium battery with other batteries.%目的 探讨镉电池厂职业性慢性镉中毒发病情况,尿镉、尿视黄醇结合蛋白(RBP)和尿β2微球蛋白(β2MG)与工龄的关系,为镉中毒的防治提供科学依据.方法 回顾分析45例职业性慢性镉中毒病例,采用职业卫生学调查、工作场所职业病危害因素现场检测和职业健康检查进行综合分析.结果 工作场所空气中镉浓度0.001~0.848mg/m3,超过《工作场所有害因素职业接触限值》GBZ2.1 ~ 2007的要求;45例病例中,RBP与β2MG含量有直线相关关系,尿镉与RBP、β2MG及工龄之间均

  20. 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.

    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.

    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.

  6. 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.

    1984-09-01

    Naturally occurring cases of poisoning of cattle by Cestrum parqui were characterised by ataxia, depression, recumbency, convulsions and death. Three cattle were dosed experimentally by intrarumenal administration of fresh plant material. One calf died 48 h after receiving 30 g (wet weight) of plant/kg bodyweight. Doses of 11 and 17 g/kg caused only mild intoxication, with dullness and anorexia lasting 2 days. In natural and experimental cases the main lesion was hepatic periacinar necrosis. Elevated levels of plasma aspartate transaminase and prolonged prothrombin times were demonstrated in experimental cases. Haemorrhage beneath the serosa and into the intestinal lumen occurred in field cases, but not in the experimental. It is concluded that C. parqui poisoning in cattle is a primary hepatotoxicity.

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

    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.

  18. Hemlock alkaloids from Socrates to poison aloes.

    Science.gov (United States)

    Reynolds, Tom

    2005-06-01

    Hemlock (Conium maculatum L. Umbelliferae) has long been known as a poisonous plant. Toxicity is due to a group of piperidine alkaloids of which the representative members are coniine and gamma-coniceine. The latter is the more toxic and is the first formed biosynthetically. Its levels in relation to coniine vary widely according to environmental conditions and to provenance of the plants. Surprisingly, these piperidine alkaloids have turned up in quite unrelated species in the monocotyledons as well as the dicotyledons. Aloes, for instance, important medicinal plants, are not regarded as poisonous although some species are very bitter. Nevertheless a small number of mostly local species contain the alkaloids, especially gamma-coniceine and there have been records of human poisoning. The compounds are recognized by their characteristic mousy smell. Both acute and chronic symptoms have been described. The compounds are neurotoxins and death results from respiratory failure, recalling the effects of curare. Chronic non-lethal ingestion by pregnant livestock leads to foetal malformation. Both acute and chronic toxicity are seen with stock in damp meadows and have been recorded as problems especially in North America. The alkaloids derive biosynthetically from acetate units via the polyketide pathway in contrast to other piperidine alkaloids which derive from lysine.

    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.

    A couple suffered for 5 years from recurrent eruptions with vesicles and bullae after contact with an unknown "climbing weed" in their private garden in Germany. After this plant was identified as poison ivy and eradicated, their skin problems were solved. This is the first report of poison ivy in this setting. Urushiols in poison ivy are not only strong allergens but also potent irritants. Negative patch tests in the husband suggest that the bullous dermatitis was a toxic reaction.

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

    This is the second in a series of three review articles on animal poisoning in Europe and focuses on cases in pet animals and horses in five European countries (Belgium, France, Greece, Italy and Spain) reported over the last decade. In the participating countries, dogs were the most commonly poisoned species, particularly younger animals. The majority of cases in companion animals resulted from exposure to insecticides, although rodenticides (especially anticoagulants and strychnine) posed a significant risk. In all five countries, horses and cats appeared to be more susceptible to plant toxins. Intoxications with herbicides, metals, household products and drugs for veterinary and human use were reported sporadically. The review demonstrates the importance of increased awareness so as to minimise poisoning episodes and emphasises the need to establish a European system for the recording of poisoning data. 2009 Elsevier Ltd.

    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.

  8. Arsenic poisoning in livestock.

    el Bahri, L; Ben Romdane, S

    1991-06-01

    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).

  9. 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.

    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.

    de 53.473 bovinos, 4.799 caprinos, 9.149 ovinos e 7.060 equídeos.A survey on toxic plants for ruminants and equidae was performed on the municipalities of Juazeiro do Norte, Crato, Barbalha, and Missão Velha on the Ceará state, Northeastern Brazil. Twenty one interviews were realized with farmers, veterinary practitioners, agronomists and agriculture technicians. Poisonings by Ipomoea asarifolia mentioned in 38% and 19% interviews as toxic for bovines and sheep, respectively, and Enterolobium contotisiliquum, mentioned as toxic for cattle (47.6% of the interviews and sheep (4.7%, were more frequent. Also occur in the region poisonings by Mascagnia rigida (38% of the interviews, Anadenanthera colubrina var. cebil (=A. macrocarpa (14%, Ricinus communis (14%, Thiloa glaucocarpa (9%, and Sorghum halepense (4% in cattle, Mimosa tenuiflora in cattle, sheep, and goats (38%, Brachiaria decumbens in sheep and cattle (38%, Manihot spp. in cattle and goats (28% , and Leucaena leucocephala in sheep and horses (4%. Several plants previously unknown as toxic, but mentioned by the respondents as poisonous, were given to experimental animals at different doses. Only Casearia commersoniana was toxic to goats at the daily doses of 20g kg-1 body weight during 2-4 days. Clinical signs, similar to those reported by the farmers, were stiffness, mild bloat, polaquiuria, vocalization, jugular engorgement and pulsation, swaying gait, falling, spasticity, paddling movements, opisthotonos, and tachyicardia and dyspnea followed by bradycardia and bradypnea. Deaths occurred 6 and 19 hours after first clinical signs. No significant gross or histologic lesions were observed. It is concluded that poisonings by plants are important cause of losses in the region, which has a population of 53,473 bovines, 4,799 goats, 9,149 sheep, and 7,060 equidae.

    2002-03-10

    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).

    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.

    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...

    2008-03-01

    Accidental aconitine poisoning is extremely rare in North America. This report describes the confirmation of a case of accidental aconitine poisoning using a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. The case involved a 25-year-old man who died suddenly following a recreational outing with friends where he consumed a number of wild berries and plants including one that was later identified as Monkshood (Aconitum napellus). Postmortem blood and urine samples were available for analysis. All routine urine and blood toxicology screens were negative. The LC-MS/MS method allowed sensitive quantification of aconitine, the main toxin in A. napellus, and showed 3.6 and 149 microg/L in blood and urine, respectively. These concentrations were similar to that reported in other aconitine-related deaths. This case illustrates the dangers of consuming unidentified plants, and documents concentrations of aconitine in blood and urine in a fatal case of A. napallus-related poisoning.

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

    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.

  4. Digitalis poisoning: historical and forensic aspects.

    Burchell, H B

    1983-02-01

    Since the introduction of digitalis into therapy approximately 200 years ago, there have been continuing admonitions concerning its toxicity. Over 400 years ago, herbalists listed the plant as being poisonous. In fiction, the homicidal use of digitalis has appeared in the writings of Mary Webb, Dorothy Sayers and Agatha Christie. Ten instances in real life of alleged homicide by digitalis and trials of the accused are listed. The drug has been used with suicidal intent rather infrequently, compared with other medications. Possibly, it is more commonly used for such a purpose in France than in England or the United States. The fraudulent use of digitalis in the support of claims for disability because of heart disease has occurred, and one large conspiracy of physicians and lawyers in the swindle of insurance companies during the 1930s is a shameful episode in the record of these professions. Although innocent, one professor of medicine who was involved committed suicide. Two pharmaceutical (manufacturing) blunders that occurred in Belgium and Holland with mislabeling are mentioned. These resulted in numerous deaths and the profession seemed rather slow to recognize the nature of these small epidemics of poisoning. Instances of psychiatric illness with digitalis seem well documented. The story of digitalis toxicity continues into the present and physicians should be vigilant regarding the drug's potential for poisoning that can result from prescribing digitalis with ignorance of proper dosage, pharmacodynamics or drug interactions, as well as from accidental overdose as in children and use with self-destructive or homicidal intent.

    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.

    Doxylamine is an antihistamine of the ethanolamine class. It is used primarily as a sleep-inducing agent. Only a few reports can be found in the literature about lethal intoxications with doxylamine, but many with combined intoxications. Doxylamine is, aside from diphenhydramine, the only chemically defined active ingredient in some sleeping medications which is available without a prescription in the Federal Republic of Germany. Two cases of doxylamine poisoning are presented, in which high doxylamine concentrations were found in the blood and organs.

    Neonatal mercury poisoning, especially that due to merbromin ingestion, is uncommon. We describe the case of a 10 day old newborn infant who was given mercurochrome orally for 7 days due to misunderstanding of medical instructions. Initial symptoms included loss of appetite and low weight increase. Elevated blood mercury concentrations were found. Chelating therapy with dimercaprol was initiated and the patient's evolution was good. We discuss the potential toxicity of mercury and emphasise the importance of the transmission of information by physicians, especially to the immigrant population.

    Juniper tar (cade oil) is distilled from the branches and wood of Juniperus oxycedrus. It contains etheric oils, triterpene and phenols, and is used for many purposes in folk medicine. A case is reported of a previously healthy man who ingested a spoonful of home-made extract of Juniperus oxycedrus. The poisoning caused fever, severe hypotension, renal failure, hepatotoxicity, and severe cutaneous burns on the face. After supportive and symptomatic treatment, the patient improved and was discharged in a good condition on the eleventh day.

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

    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.

  18. 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.

    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.

    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.

    Full Text Available Organophosphates, which can cause occupational poisoning due to inappropriate personal protective measures, are widely used insecticides in agricultural regions of southern Turkey. Therefore, the classical clinical findings of this cholinergic poisoning are myosis, excessive secretions, bradicardia and fasciculations are easy to be recognized by local medical stuff. Diseases and conditions related to alcoholism such as mental and social impairments, coma, toxicity, withdrawal, and delirium are frequent causes of emergency visits of chronic alcoholic patients. Here we present a case diagnosed and treated as organophosphate poisoning although it was an alcohol withdrawal in the beginning and became delirium tremens, due to similar symptoms.

    2010-03-01

    The lack of a reference Veterinary Poison Control Centre for the European Union (EU) means that clinicians find it difficult to obtain information on poisoning episodes. This three-part review collates published and unpublished data obtained from Belgium, France, Greece, Italy and Spain over the last decade in order to provide a broader toxicoepidemiological perspective. The first article critically evaluates the national situation in the five European countries and concludes that information for livestock and poultry is limited and fragmentary compared to other animal groups. The analysis has revealed that clinical cases of poisoning are only occasionally studied in depth and that cattle are the species most frequently reported. Several plants and mycotoxins, a few pesticides and metals, together with contaminants of industrial origin, such as dioxins, are responsible for most of the recorded cases. 2009 Elsevier Ltd.

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

    Science.gov (United States)

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

    2006-01-01

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

    2014-09-01

    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.

  7. Fatal aluminium phosphide poisoning

    Directory of Open Access Journals (Sweden)

    Meena Mahesh Chand

    2015-06-01

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

    2009-04-01

    Poisoning by Sida carpinifolia belongs to a group of plant-induced phenotype which resembles lysosomal storage diseases. Saanen goats were fed aerial parts of green S. carpinifolia for up to 3 months. Concentrates complemented the nutritional requirements. Urine and blood samples were collected for oligosaccharide study (by thin layer chromatography-TLC) and hemogram analysis, respectively. Abnormal excretion of oligosaccharides was observed from the 2nd day of S. carpinifolia ingestion until one day after withdrawal of the plant from the diet. There were no changes in hemogram. Clinical signs were typical of poisoning caused by plants of this group and were seen from the 37th day on S. carpinifolia diet until seven days after withdrawal of the plant, when signs gradually became scarce and less evident. Results presented here suggest that detection of urinary oligosaccharides by TLC may be an useful method to assess swainsonine-containing plants exposure or an early diagnostic tool for poisoning by these plants.

    1989-04-01

    19 adults were patch tested to urushiol, the allergen in poison ivy/oak, to determine their sensitivity to this allergen after working in a cashew nut shell oil (CNSO) processing plant. The cashew nut tree and poison ivy/oak are in the same botanical family. Anacardiaceae, and they share similar chemicals which cause allergic contact dermatitis. 13 of the 19 workers had a preemployment history of poison ivy sensitivity, with 10 developing CNSO dermatitis. After working in this factory for several months, 9 of the 13 noticed a decreased sensitivity or no sensitivity to poison ivy/oak. When tested to urushiol extract, only 3 reacted positively, 2 minimally. These results imply that hyposensitization to poison ivy/oak occurred in these employees after development of hardening to cashew nut shell oil.

    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 Toxic effects that occur after acute organophosphate poisoning (OP can manifest three phases, namely, acute cholinergic crisis, intermediate syndrome and delayed-type polyneuropathy. Clinical signs and symptoms of organophosphate poisoning depend on the accumulation of acetylcholine at the nerve junction. Organophosphate poisoning causes three main clinical findings; acute cholinergic crisis consisting of muscarinic, nicotinic and central nervous system symptoms, intermediate syndrome with recurrence of cholinergic symptoms or muscle weakness without fasciculation 24-96 hours after poisoning and delayed-type polyneuropathy that can usually occur several days or weeks after acute exposure to organic phosphorus compounds. In this article, intermediate syndrome, which is a late complication, has been reviewed. [Archives Medical Review Journal 2016; 25(1.000: 70-83

    The history of curare is both curious and convoluted. A product of South American culture it emerged in the sixteenth century from the mists of antiquity at the same time as quinine, coca, and chocolate. Like quinine, at first came the extract but no plant, and later the plant but no chemical compound. It took more than 300 years and the efforts of many explorers and scientists to resolve the problem. These included Condamine, Humboldt, Brodie, Waterton, Bernard, Dale, Walker, and King. Finally, the pure compound d-tubocurarine was isolated from the liana Chondrodendron and synthesised. Its specific physiological action was blockade of the effect of acetylcholine at the neuro-muscular junction. Such a paralytic poison could be used to kill oneself or others. The bizarre plot to kill the Prime Minister, Lloyd George, during the First World War is described. Fortunately this nefarious plan was thwarted by the Secret Service!

    Briant, D; Brouder, G

    1983-01-01

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

  4. 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.

  5. The effectiveness of different interventions to promote poison prevention behaviours in households with children: a network meta-analysis.

    Full Text Available There is evidence from 2 previous meta-analyses that interventions to promote poison prevention behaviours are effective in increasing a range of poison prevention practices in households with children. The published meta-analyses compared any intervention against a "usual care or no intervention" which potentially limits the usefulness of the analysis to decision makers. We aim to use network meta-analysis to simultaneously evaluate the effectiveness of different interventions to increase prevalence of safe storage of i Medicines only, ii Other household products only, iii Poisons (both medicines and non-medicines, iv Poisonous plants; and v Possession of poison control centre (PCC telephone number in households with children.Data on the effectiveness of poison prevention interventions was extracted from primary studies identified in 2 newly-undertaken systematic reviews. Effect estimates were pooled across studies using a random effects network meta-analysis model.28 of the 47 primary studies identified were included in the analysis. Compared to usual care intervention, the intervention with education and low cost/free equipment elements was most effective in promoting safe storage of medicines (odds ratio 2.51, 95% credible interval 1.01 to 6.00 while interventions with education, low cost/free equipment, home safety inspection and fitting components were most effective in promoting safe storage of other household products (2.52, 1.12 to 7.13, safe storage of poisons (11.10, 1.60 to 141.50 and possession of PCC number (38.82, 2.19 to 687.10.

    Science.gov (United States)

    Ligabue-Braun, Rodrigo; Carlini, Célia Regina

    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.

  13. Industrial fluoride pollution: chronic fluoride poisoning in Cornwall Island cattle

    Energy Technology Data Exchange (ETDEWEB)

    Krook, L.; Maylin, G.A.

    1979-04-01

    An aluminum plant on the south bank of the St. Lawrence River, southwest of Cornwall Island, Ontario, Canada, has emitted 0.816 metric tons of fluoride daily since 1973. Considerably higher amounts were emitted from 1959 to 1973. The plant was designated as the major source of fluoride emissions impacting on Cornwall Island. Cattle located on this island showed signs of chronic fluoride poisoning. This poisoning was manifested clinically by stunted growth and dental fluorosis to a degree of severe interference with drinking and mastication. This Cornwall Island herds study indicates that the established tolerance level of fluoride for performance of dairy and beef cattle is not valid since the tolerance level was set based on experiments with healthy calves which were exposed to dietary fluoride from 3 to 4 months of age and not on cattle which were chronically exposed to fluoride from conception to death. 56 references.

    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.

    Within 3 days two female patients presented with an eruption featuring erythema, edema, vesicles and bullae. We suspected poison ivy allergy which was subsequently proven by history and positive patch tests. In Germany the risk of specific hypersensitivity to Toxicodendron species is low, since the distribution of such plants is confined to botanical gardens. Other species belonging to the family of Anacardiaceae contain urushiols as well (e.g., mango, cashew) and may cause allergic contact dermatitis.

    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.

    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.

    Between October 1982 and June 1983, 43 patients were identified with symptomatic lead poisoning in three Arab villages of the Nablus district. 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.

    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.

    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

    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.

    2015-05-01

    This article reports the case of a 62-year-old male patient who ingested the roots of Monkshood (Aconitum napellus) and white hellebore (Veratrum album) dissolved in alcohol with a suicidal intention and suffered cardiotoxic and neurotoxic symptoms. After contacting the Poison Information Centre ventricular arrhythmia was treated with high-dose magnesium sulphate as the only antiarrhythmic agent and subsequently a stable sinus rhythm could be established after approximately 3 h. Aconitum napellus is considered the most poisonous plant in Europe and it is found in gardens, the Alps and the Highlands. Poisoning is mainly caused by the alkaloid aconite that leads to persistent opening and activation of voltage-dependent sodium channels resulting in severe cardiac and neurological toxicity. As no specific antidote is known so far, poisoning is associated with a high mortality. The therapy with high-dose magnesium sulphate is based on in vitro and animal experiments as well as limited clinical case reports.

    Paraquat is quick-acting and non-selective, killing green plant tissue on contact; it is also toxic to human beings and animals. In this study, we developed a urine metabonomic method by gas chromatography-mass spectrometry to evaluate the effect of acute paraquat poisoning on rats. Pattern recognition analysis, including both partial least squares discriminate analysis and principal component analysis revealed that acute paraquat poisoning induced metabolic perturbations. Compared with the control group, the levels of benzeneacetic acid and hexadecanoic acid of the acute paraquat poisoning group (intragastric administration 36 mg/kg) increased, while the levels of butanedioic acid, pentanedioic acid, altronic acid decreased. Based on these urinary metabolomics data, support vector machine was applied to discriminate the metabolomic change of paraquat groups from the control group, which achieved 100% classification accuracy. In conclusion, metabonomic method combined with support vector machine can be used as a useful diagnostic tool in paraquat-poisoned rats.

    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.

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

    Full Text Available The aim of this study was to describe the bone changes observed after a daily oral administration of the calcinogenic plant Solanum malacoxylon (syn. S. glaucophyllum (Sm during 9 days. The Sm-poisoned rabbits had an increase of bone resorption in the endosteal surface of the cortical zone and also in the surface covered by osteoblasts of the primary and secondary spongiosa of the trabecular bone compartment. Moreover, the epiphyseal growth plates in long bones appeared narrower than in the control rabbits, with reduction of the proliferative and hyperthrophic chondrocyte zones. The electron microscopic study revealed a significant decrease of proteoglycans in the hyperthrophic chondrocyte zone evidenced by a significant reduction of rutenium red positive granules in the poisoned rabbit. Altogether, these data suggest that cell differentiation may play a pivotal role in the pathogenesis of Sm-induced bone lesions.

    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.

    Ferula communis (L.), a plant belonging to Apiaceae, is widely present in Sardinia, Italy. Currently, interest in F. communis focuses on the presence of two chemotypes in the wild. One chemotype is poisonous to animals, whereas the other chemotype is non-poisonous. Polyphenol oxidase (PPO) has been extracted and partially purified from the two chemotypes of F. communis. The biochemical characterization of the enzymes showed significant differences. In particular, while the two PPOs were not able to use 6- and 7-hydroxycoumarin as substrates, they showed distinct specificity for 6,7- and 7,8-dihydroxycoumarin. Significant differences in the enzyme behavior towards common PPO inhibitors were also observed. In addition, activation energy and activation energy for denaturation were determined, showing significant differences between FP-PPO and FNP-PPO, particularly for denaturation kinetics. The possible roles of the two PPOs in determining differences in composition and toxicity of the two F. communis chemotypes are also discussed.

    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 report...

    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.

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

    ância das intoxicações por plantas na região Norte do Brasil.A survey about the presence of toxic plants and the occurrence of outbreaks of poisoning in ruminants and equidae was performed in 12 municipalities of the central region of the state of Rondônia. Ninety eight persons were interviewed, including farmers, veterinary practitioners, agronomists, and agrarian technicians. Thirty four farmers reported poisoning by toxic plants, including poisoning by Palicourea marcgravii (12 outbreaks, Palicourea grandiflora and Enterolobium contortisiliquum (seven outbreaks each, and Palicourea juruana, Brachiaria radicans, Brachiaria brizantha, and Manihot esculenta (two outbreaks each. In sheep, farmers reported two outbreaks of photosensitization caused by Brachiaria decumbens and one outbreak of sudden death caused by Palicourea grandiflora. In the 34 outbreaks, 374 (8,9% bovines were affected and 311 (7.4% died, from a total of 4.192 cattle exposed. In the three outbreaks in sheep, 28 animals were affected and 20 died out of 250 exposed. Amorimia sp., previously misidentified as Mascagnia sepium, a previously unreported toxic plant, was identified as a cause of sudden death in sheep and cattle in 32% of the farms. Fifteen outbreaks of colic in horses grazing Panicum maximum (cultivars 'Massai', 'Tanzânia', and 'Mombaça' during the rainy season were also reported. It is concluded that poisoning by toxic plants is an important cause of economic losses in livestock in the region studied. With the results of this research the number of known toxic plant for ruminants in central region of Rondônia increased from one to nine, indicating that more research is necessary for the knowledge of poisonous plants for livestock in the Brazilian Amazonic region.

    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.

    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.

    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.

    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

    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.

    Brown, Jason L.; Morales, Victor; Summers, Kyle

    2008-01-01

    We report an unusual example of reproductive parasitism in amphibians. Dendrobates variabilis, an Amazonian poison frog, oviposits at the surface of the water in small pools in plants and deposits tadpoles within the pools. Tadpoles are highly cannibalistic and consume young tadpoles if they are accessible. Deposition of embryos and tadpoles in the same pool is common. Genetic analyses indicate that tadpoles are frequently unrelated to embryos in the same pool. A pool choice experiment in the field demonstrated that males carrying tadpoles prefer to place them in pools with embryos, facilitating reproductive parasitism via cannibalism. PMID:19042178

  16. The treatment of acetaminophen poisoning

    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.

  17. 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

  18. 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.

    2010-06-23

    Cattle grazing in arid rangelands of Australia suffer periodic extensive and serious poisoning by the plant species Pimelea trichostachya, P. simplex, and P. elongata. Pimelea poisoning (also known as St. George disease and Marree disease) has been attributed to the presence of the diterpenoid orthoester simplexin in these species. However, literature relating to previous studies is complicated by taxonomic revisions, and the presence of simplexin has not previously been verified in all currently recognized taxa capable of inducing pimelea poisoning syndrome, with no previous chemical studies of P. trichostachya (as currently classified) or P. simplex subsp. continua. We report here the isolation of simplexin from P. trichostachya and the development of a liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) method to measure simplexin concentrations in pimelea plant material. Simplexin was quantified by positive-ion atmospheric pressure chemical ionization (APCI) LC-MS/MS with selected reaction monitoring (SRM) of the m/z 533.3 > 253.3 transition. LC-MS/MS analysis of the four poisonous taxa P. trichostachya, P. elongata, P. simplex subsp. continua, and P. simplex subsp. simplex showed similar profiles with simplexin as the major diterpenoid ester component in all four taxa accompanied by varying amounts of related orthoesters. Similar analyses of P. decora, P. haematostachya, and P. microcephala also demonstrated the presence of simplexin in these species but at far lower concentrations, consistent with the limited reports of stock poisoning associated with these species. The less common, shrubby species P. penicillaris contained simplexin at up to 55 mg/kg dry weight and would be expected to cause poisoning if animals consumed sufficient plant material.

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

    Renier, J.A.

    2002-04-17

    water reactor fuel core was chosen for the study, and state-of-the-art neutronic reactor core computer codes were used for analysis. Power distribution, fuel burnup, reactivity due to burnable poisons and other fission products, spectrum shift, core reactivity, moderator void coefficients, as well as other parameters were calculated as a function of time and fuel burnup. The results not only showed advantages of separation of burnable poison isotopes but revealed benefits to be achieved by careful selection of the configuration of even naturally occurring elements used as burnable poisons. The savings in terms of additional days of operation is shown in Figure 1, where the savings is plotted for each of six favorable isotopes in the four configurations. The benefit of isotope separation is most dramatic for dysprosium, but even the time savings in the case of gadolinium is several days. For a modern nuclear plant, one day's worth of electricity is worth about one million dollars, so the resulting savings of only a few days is considerable. It is also apparent that the amount of savings depends upon the configuration of the burnable poison.

In cattle, 7.4% of the diseases diagnosed were caused by poisonous plants. Outbreaks were caused by Centhraterum brachylepis (1, Brachiaria spp. (1, Crotalaria retusa (2, Ipomoea batatas (1, Marsdenia sp. (1, grass containing nitrites (3 outbreaks, 1 by Echinochloa polystachya and 2 by Pennisetum purpureum, Palicourea aeneofusca (1, Prosopis juliflora (3, Nerium oleander (1, and Mimosa tenuiflora (7. In sheep, 13% of the diseases diagnosed were caused by toxic plants. Four outbreaks were caused by Ipomoea asarifolia, 3 by Brachiaria spp., 2 by Crotalaria retusa, 2 by Tephrosia cinerea, 1 by Panicum dichotomiflorum, 1 by Mascagnia rigida, and 20 by Mimosa tenuiflora. In goats, 6.4% of the diseases were caused by toxic plants. Seven outbreaks were caused by Mimosa tenuiflora, 1 by Ipomoea asarifolia, 1 by Ipomoea carnea, 1 by Ipomoea riedelli, 3 by Prosopis juliflora, 1 by Arrabidaea corallina, 2 by Aspidosperma pyrifolium, and 2 by Turbina cordata. In horses, 14% of the diagnosed diseases were due to plants poisonings including 12 outbreaks caused by Crotalaria retusa and one by Turbina cordata. Annual losses in the state of Paraíba by deaths of livestock are estimated in 3,895 cattle, 8,374 sheep, 6,390 goats, and 366 horses, which represent about US$ 1,380,000. Epidemiologic, clinical and pathologic aspects of poisonings by Crotalaria retusa in cattle, Brachiaria spp. in sheep, Prosopis juliflora in cattle and goats, Nerium oleander in cattle, Opuntia ficus-indica in goats, and Turbina cordata in horses and goats are reported.

    2016-01-01

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

    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.

    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.

    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.

    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.

    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.

  16. Chronic mercury poisoning: Report of two siblings

    Full Text Available 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.

    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.

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

    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.

    2009-06-01

    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.

    da planta pelos ovinos e, as folhas mantiveram sua toxicidade quando dessecadas.Simarouba versicolor St. Hil. is a semideciduous tree belonging to the Simaroubaceae family. An outbreak of poisoning in cattle by shoots of S. versicolor present in the pasture in Mato Grosso do Sul and experimental reproduction of the poisoning was described. This study aimed to verify experimentally whether sheep could be used as a clinical-pathological model in the study of the poisoning caused by S. versicolor, to determine if there develops resistance induced by ingestion of small and repeated doses of the leaves, and if the plant keeps its toxicity when dried. Two experiments were conducted: Experiment 1 with green leaves or dried and powdered leave of S. versicolor, given in single doses of 5g/kg, 5g/kg and 3g/kg to three sheep (Sheep 1, 2 and 3 respectively. Experiment 2 was made with different daily doses of dried and powdered leaves of S. versicolor; to four sheep was given 1.5g/kg, 0.75g/kg, 0.6g/kg and 0.3g/kg, and the positive control (Sheep 4 received 3g/kg. The administration was suspended when the animals showed clinical signs of poisoning. After twelve days of recovery, the surviving sheep were challenged with the same daily dose given previously, to assess the development of resistance. Clinical signs observed in both experiments were characterized by anorexia, congested ocular mucosa, polydipsia, drooling, loose stools which evolved into fetid greenish watery diarrhea, lateral decumbency and death of Sheep 1 to 7. The main histological lesions observed were necrosis of lymphoid tissue (lymph nodes, spleen, Peyer's patches and necrotizing enteritis. With the results it can be concluded that sheep can be used as experimental model for the clinic-pathological aspects of poisoning by S. versicolor. The method used has not shown resistance to the daily consumption of the plant by the sheep, and the leaves kept their toxicity when dried.

  1. 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.

    In Europe, as opposed to North America, poison-ivy rash is hardly known. For this reason a detailed review of the allergenic members of the Anacardiaceae family is given, and the misleading nomenclature of "poison ivy", "poison oak", and some other species of this family are discussed. An up-to-date representation of the chemical structure of the allergenic substance group (denoted as "Urushiol") from this family is provided as well as botanical information regarding the plants themselves. Prevention of this dangerous sensitization and the therapy of this allergic reaction are discussed. The four cases presented are as follows: a young German woman who became sensitized to poison ivy or poison oak while in the USA and showed a cross reaction to other Rhus species (R. copallina, R. javanica (semialata), R. trichocarpa) as well as to Choerospondias axillaris var. japonica and to mangoes; a landscape gardener with an occupationally acquired allergy to Anacardium occidentale; and two control persons giving positive results to skin tests with Urushiol and Rhus trichocarpa respectively, to which the source of sensitization could not be clarified. Tests with three kinds of pistachio and two native-European Anacardiaceae (Rhus typhina and Cotinus coggygria) yielded negative results in each case. Prophylaxis to sensitization requires familiarity with the numerous Anacardiaceae and derivative products to which one could come in contact. These substances, summarized in a table, include mango, cashew and "sweet pepper".

  7. Lead poisoning in captive wild animals

    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.

    2016-01-01

    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.

    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

    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 Nitrite poisoning in pigs was suspected when 4 of 18 pigs died in a piggery near Ellisras in the Northern Province. The pigs showed typical brownish discolouration of the blood at autopsy. It was established that they ingested vegetable tops and weeds from the adjacent garden as part of their daily ration. Of the available plants, only Capsella bursa-pastoris contained nitrites. The drinking water and some of the other plants tested positive for nitrates but not for nitrites. This is the first report of suspected nitrite poisoning in pigs caused by Capsella bursa-pastoris.

  7. Aluminum phosphide poisoning: an unsolved riddle.

    Science.gov (United States)

    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.

    2014-12-01

    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.

  9. Toad poisoning in three dogs: case reports

    Directory of Open Access Journals (Sweden)

    CM Barbosa

    2009-01-01

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

    Livestock poisoning by plants is a frequent occurrence which determines severe losses, such as the fall in the milk and meat production, the cost of expensive treatments, the state of immunosuppression, or even the animal's death. Cattle ingest toxic plants only when there is food shortage, when they cannot select what they eat, or when they ingest food for preference, which is the case of Hovenia dulcis fruits, very rich in sucrose. This plant is widely distributed in the southern and southeastern Brazilian regions. In literature, there are some cases of severe human liver injury associated with a long-term of H. dulcis leaf and fruit tea intake, and only one report regarding spontaneous poisoning of goats caused by this plant ingestion. However, its toxic effects associated with spontaneous ingestion by cattle have never been reported. This paper reports the first case of spontaneous poisoning in cattle by H. dulcis, which occurred in a dairy farm in southwest Paraná, Brazil. Three cattle individuals showed anorexia, ruminal atony, severe diarrhea and neurological tournament, head pressing, blindness, ataxia, and circling. The necropsy of the animals was done, and the remaining alterations were restricted to the digestive system and brain. The clinical signs presented by the animals are characteristic of polioencephalomalacia (PEM), caused by changes in the thiamine metabolism. Furthermore, clinical signs, gross, and microscopic lesions as well as the large amount of the plant throughout the digestive segment led to a diagnosis.

    Contact with poison ivy (Toxicodendron radicans) is one of the most widely reported ailments at poison centers in the United States, and this plant has been introduced throughout the world, where it occurs with other allergenic members of the cashew family (Anacardiaceae). Approximately 80% of humans develop dermatitis upon exposure to the carbon-based active compound, urushiol. It is not known how poison ivy might respond to increasing concentrations of atmospheric carbon dioxide (CO(2)), but previous work done in controlled growth chambers shows that other vines exhibit large growth enhancement from elevated CO(2). Rising CO(2) is potentially responsible for the increased vine abundance that is inhibiting forest regeneration and increasing tree mortality around the world. In this 6-year study at the Duke University Free-Air CO(2) Enrichment experiment, we show that elevated atmospheric CO(2) in an intact forest ecosystem increases photosynthesis, water use efficiency, growth, and population biomass of poison ivy. The CO(2) growth stimulation exceeds that of most other woody species. Furthermore, high-CO(2) plants produce a more allergenic form of urushiol. Our results indicate that Toxicodendron taxa will become more abundant and more "toxic" in the future, potentially affecting global forest dynamics and human health.

    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.

    @@ 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.

    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 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.

    2009-01-01

    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

    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.

    A black spot in the epidermis over a blister of poison ivy dermatitis is an uncommon finding. Four patients with the phenomenon are described. Histologic and histochemical studies were made on biopsy material and the blackish deposit on the skin surface was compared with black deposits in and on leaves of the species of poison ivy. This examination revealed a yellow, amorphous substance on the stratum corneum of the lesions and a similar substance in and on leaves of the poison ivy plant, Toxicodendron radicans ssp. negundo. Associated with the pigmentary deposits there were distinct changes of acute irritant contact dermatitis superimposed upon allergic contact dermatitis. Our findings support the view that the black material is the oleoresin of the plant, and that this substance behaves both as an irritant and an allergen.

    Full Text Available Pyrrolizidine alkaloids (PAs are natural phytotoxins found in thousands of plant species around the world. They are probably the most common poisonous plants affecting livestock, wildlife and humans. The disease occurs almost entirely as a consequence of chronic poisoning and in general ends fatally. In the present study, PAs poisoning was investigated in a gazelle with hepatic encephalopathy associated with severe neurologic signs. The main clinical signs included head pressing, progressive depression and weakness, ataxia and reluctance to move, turn the head to the left and to paddle, hyperesthesia and decreased food intake. Histopathological examination revealed major lesions in the liver consisting of severe hepatocyte megalocytosis and hypertrophy with nuclei enlargement, mild bile duct hyperplasia, centriacinar fatty change and hepatocellular necrosis. Moreover, pulmonary congestion and edema with endothelium necrosis and alveolar septa thickening, severe congestion in vessels of the brain and meninges, and myocardial necrosis were observed.

    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.

    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.

    2008-01-01

    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.

    An outbreak of methylmercury poisoning took place in the fall and winter of 1971 to 1972 in Iraq. Six thousand five hundred and thirty cases were admitted to hospitals throughout the country and 459 died in hospital. The outbreak was the result of eating homemade bread prepared from wheat treated with a methylmercury fungicide. The wheat was intended for planting purposes only. Signs and symptoms of poisonings in adults indicate that the major site of action of this form of mercury is the central nervous system. Severe brain damage also resulted from prenatal exposure when the mother ingested large amounts of the contaminated bread. The frequency of signs and symptoms in an exposed population was found to be related to the estimated maximum blood levels, i.e., the concentration in blood at the end of exposure. A small percentage of the population exhibited a significant increase in complaints of paresthesia at maximum blood levels in the range of 240 to 480 ng Hg/ml. At higher blood levels a greater proportion of the population complained of paresthesia and other signs and symptoms became apparent.

    We present a case of acute lethal poisoning by oil of "epazote" (oil of chenopodium), in a 2 y 9 m female. The volatile oil was administered according to the advice of a "curandera" (female healer), in a total quantity of 40 ml. Clinical features of the poisoning were: vomiting, deep coma, seizures, mydriasis, apnea, metabolic acidosis, neurogenic shock and death. The EEG suggested a diffuse encephalopathy, the CT scan with an image of severe brain edema and ventricular collapse. Relevant postmortem findings were brain edema and neuronal necrosis, pneumonia, enteritis, pericholangitis, mild pancreatitis and tubular necrosis. The phytochemical analysis of volatile oil identified ascaridol, the main active compound of the chenopodium herbs, in a quantity of 39 mg/ml (1,560 mg in the dose administered), and Chenopodium graveolens as the plant employed to prepare it. According to the age of the patient, 60 mg of ascaridol would be the recommended dose formerly used in the treatment of parasitic disease. Thus 1,560 mg was 26 times higher than the recommended dose, and exceeded by 56% the dose of 1,000 mg reported as lethal in humans.

    A case of fatal poisoning due to ingestion of the plant Rumex crispus (curled dock) is described. The patient, a 53-year-old male, presented with gastrointestinal symptoms, severe hypocalcemia, metabolic acidosis and acute hepatic insufficiency. Despite therapeutic measures, the patient died 72 h after ingestion of the plant material. Noteworthy among the pathological findings were centrolobular hepatic necrosis and birefringent crystals in the liver and kidneys that were identified by histochemical techniques and scanning electron microscopy. These observations are compared with other reports in the medical literature, with an emphasis on the risk involved in the use of these plants for culinary or medicinal purposes.

    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.

  6. Acute Lantana camara poisoning in a Boer goat kid : case report

    Directory of Open Access Journals (Sweden)

    A. Ide

    1998-07-01

    Full Text Available Acute Lantana camara poisoning in a Boer goat kid is described. The animal was part of a flock of boer goats that was introduced from the Kalahari thornveld, where the plant does not occur, to an area where the plant grew abundantly. At necropsy, the animal was severely icteric, dehydrated and constipated, with hepatosis, distention of the gall-bladder and nephrosis, but no skin lesions. Histopathological findings of the liver confirmed moderate hepatosis with single-cell necrosis and bile stasis. The pathology is consistent with that described in acute Lantana poisoning in cattle, sheep and goats. The absence of photosensitisation may be attributed to relatively mild liver damage, or the rapid course of this toxicosis.

    2013-01-01

    Background: In 2010, Médecins Sans Frontières discovered a lead poisoning outbreak linked to artisanal gold processing in northwestern Nigeria. The outbreak has killed approximately 400 young children and affected thousands more. Objectives: Our aim was to undertake an interdisciplinary geological- and health-science assessment to clarify lead sources and exposure pathways, identify additional toxicants of concern and populations at risk, and examine potential for similar lead poisoning globally. Methods: We applied diverse analytical methods to ore samples, soil and sweep samples from villages and family compounds, and plant foodstuff samples. Results: Natural weathering of lead-rich gold ores before mining formed abundant, highly gastric-bioaccessible lead carbonates. The same fingerprint of lead minerals found in all sample types confirms that ore processing caused extreme contamination, with up to 185,000 ppm lead in soils/sweep samples and up to 145 ppm lead in plant foodstuffs. Incidental ingestion of soils via hand-to-mouth transmission and of dusts cleared from the respiratory tract is the dominant exposure pathway. Consumption of water and foodstuffs contaminated by the processing is likely lesser, but these are still significant exposure pathways. Although young children suffered the most immediate and severe consequences, results indicate that older children, adult workers, pregnant women, and breastfed infants are also at risk for lead poisoning. Mercury, arsenic, manganese, antimony, and crystalline silica exposures pose additional health threats. Conclusions: Results inform ongoing efforts in Nigeria to assess lead contamination and poisoning, treat victims, mitigate exposures, and remediate contamination. Ore deposit geology, pre-mining weathering, and burgeoning artisanal mining may combine to cause similar lead poisoning disasters elsewhere globally.

  8. Using Poison Center Data for Postdisaster Surveillance

    2015-01-01

    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.

    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.

    Gathering and eating mushrooms and other plants containing psychoactive substances has become increasingly popular among young people experimenting with drugs. Dried fly agaric Amanita muscaria fruiting bodies were eaten by five young persons (18-21 years of age) at a party in order to evoke hallucinations. Visual and auditory hallucinations occurred in four of them, whereas a 18-year-old girl lost consciousness. The following morning, she went to the Clinic of Toxicology. Due to the fact that not all the active substances present in the fly agaric have been identified, and some of them have an effect after a period of latency, the patient was admitted for several days of observation during which check-up examinations were performed. After four days without any problems, she was discharged. The poisoning regressed with no organ complications. The remaining persons who had eaten the fly agaric were free from any complaints.

  10. Transdermal carbamate poisoning – a case of misuse

    Directory of Open Access Journals (Sweden)

    Lalit Kumar Rajbanshi

    2017-01-01

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

    Full Text Available Many wild plants around us have beneficial effects on our body and can be used as food. People are more and more interested in the medicinal plants. Many of them began gathering and preparing plants for the relief of symptoms of diseases or as a food dietary. Due to the lack of knowledge of plants, mistaking plants that contain toxins for medical plants may happen and cause adverse effects or even poisoning. The Poison Control Centre in Ljubljana keeps records of patients who have been admitted to the department because of adverse effects from the ingestion of certain plants. We analysed 64 cases, which were registered by the Poison Control Centre between January 2000 and December 2013. The aim of the present study was to determine which plants cause the most intoxications in Slovenia.

    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.

    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%.

    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.

    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.

  8. 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.

    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.

    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.

  15. Pralidoxime in carbaryl poisoning: an animal model.

    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.

A total of 1199 cases were submitted, but a diagnosis of intoxication was only established in 13.5% of cases. In these cases, overexposures to minerals, metals, and poisonous plants were determined as the most commonly diagnosed poisonings in cattle in California. Nitrate/nitrite poisoning was the most commonly diagnosed plant-associated intoxication, followed by gossypol and oleander. This study details the diagnostic challenges and treatment options for the most commonly diagnosed intoxications. To ensure proper treatment and prevention of new cases, accurate diagnosis is necessary, and therefore this review provides an essential tool for the food animal practitioner. Available toxicological analyses are offered at select laboratories, which can be time consuming and expensive, yet the potential for residues in consumed animal products and implications for human health necessitate testing and consultation. Any potential exposure to a toxicant in cattle should be reviewed to determine whether a residue hazard exists. Therapy focuses on immediate removal of the toxicant from the environment and from the gastrointestinal tract. With few antidotes available, most are cost prohibitive to treat numerous affected cattle. In addition, most antidotes will require extra-label drug use and establishment of meat and milk withdrawal times.Keywords: toxins, toxicology, poisonous plants, bovine

    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.

    Bongkrekic acid(BA) is a fatal bacterial toxin which was found in poisonous fermented cocnut product in indonesia in 1934 and the molecular structure was identified as C28H33O7 in 1960,In the 1950s,food poisoning outbreak of undnown cause occurred cause in the northeast part of China.A new toxin-producing bacterium,pseudomonas cocovenans subsp.Farinofermentans.was identified as the causal pathioge,and its metabolite BA was isolated.purfied and identified in 1979 and 1984.After that ,deteriorated tremella poisoning and viegar jelly poisoning were identified as being caused by the consumption of BA-contaminated foods.About 103 food poisoning outbreaks occurred in 16 provinces in China from 1985 to 1994,A total of 301 (out of 667) patients died.The overall fatality rate(45.13%) was the highest among all microbiological food poisonings in China.Various fermented cereal foods,deteriorated fresh tremella,potato products,sticky rice flur,polished glutious rice,sweet potato starch,noodles and vinegar jelly were in volved in the outbreaks,BA Was detected form leftover fermented corn flour,deteriorated tremella and the P.Cocovenenans subsp.farinofermentans was identifed as the source bascteria.The toxigenic strains have been found not only from the leftover food samples collected from the outbreaks.but also from normal fresh cultivated tremella in Henan and corn flour products from supermarkets in Beijing,TLC,HPLC,and MaAb-ELISA were used to detect BA in the food samples,The minimum detected levels were 0.25,0.1 and 0.2mg/kg,respectively,Further studies showed that Ba could be producted at 26 C for 5 days in potato dextrose agar(PDA) medium.Exposure to ultravioled ligh significantly reduced the level of BA in fresh tremella(96.7%-97.3%) as well as the toxin-producing ability of toxigenic stains in culture medium.
