RESUMEN
OBJECTIVE: The aim of this retrospective study was to analyze the clinical signs, confirmed or suspected toxicants, treatments and outcomes of poisoning cases in dogs presented over a 5-year period to the emergency service of a small animal referral center. MATERIAL AND METHODS: Medical records of 634 dogs were evaluated for a history of confirmed or presumed poisoning, suspected toxicant, clinical signs, treatment, and patient outcome. The probability of poisoning was graded based on the patient history, clinical findings, toxicologic examination and - in some cases - investigation of gastrointestinal contents. RESULTS: Most dogs were hospitalized (77%) due to poisoning with mostly unknown toxicants (33%), food residues (18%), rodenticides (10%), tremorgenic mycotoxins (8%), medications (7%) and various plants (7%), followed by recreational drugs (5%), chemicals (4%), molluscicides (3%), antiparasitics (2%), feces (2%), nuts (2%), or toxins of animal origin (1%). Patients were presented predominantly showing neurologic signs (56%), reduced general condition (39%), and cardiovascular or hydration status abnormalities (26%). The survival rate was 97%. Most dogs were clinically unremarkable at the time of hospital discharge (70%). An additional 18% of the survivors had no apparent complications by the time of discharge. Toxicant-related complications (20.5%) included hemorrhage (4%), hepatic (4%), renal (4%), respiratory (3%), gastrointestinal (3%), cardiovascular (3%), and/or central nervous system (3%) complications, or clinically relevant hypoglycemia (0.3%). CONCLUSION AND CLINICAL RELEVANCE: In the present study, poisoning in dogs was mostly associated with the ingestion of food residues, but the causative toxicant remained unidentified in many cases. Neurological signs were the major clinical presentation. The survival rate (97%) in this study was higher compared to those reported by other investigators.

OBJECTIVES: The aims of this study were to describe the clinical picture and progression in cats with alpha-chloralose (AC) intoxication and to determine if treatment with intravenous (IV) lipid emulsion (ILE) influenced either the serum concentration of AC or the clinical signs. METHODS: Cats with suspected AC poisoning admitted to a university small animal hospital were included. The cats were randomised into two groups: one receiving 20% ILE at a dose of 300 mg/kg as a 2 min bolus, followed by a 1500 mg/kg continuous rate infusion over 30 mins (IL+ group) and the other receiving IV fluid therapy with Ringer's acetate (IL- group). Serum samples were drawn at 0, 2, 12 and 24 h after admission. Samples were tested for AC with a novel validated, quantitative, ultra-high-performance liquid chromatography-tandem mass spectrometry method. Vital and predefined clinical signs were noted at the times of sampling and patients were scored using a previously described intoxication severity score. Telephone interviews were conducted after discharge to assess outcome. RESULTS: A total of 25 cats were enrolled: 13 cats in the IL+ group and 12 in the IL- group. The most common clinical signs at presentation were tremor (n = 22, 88.0%), cranial nerve deficits (n = 20, 80.0%) and bradycardia (n = 19, 76.0%). No significant difference in AC concentration or change in intoxication score over time was found between the IL+ and IL- groups at any time point (P >0.05). All cats recovered within 72 h. CONCLUSIONS AND RELEVANCE: ILE did not have any effect on the AC serum concentration or clinical signs in AC-poisoned cats. All cats survived until follow-up. In cats with an acute onset of the described neurological signs, AC intoxication is an important differential diagnosis with an excellent prognosis.

OBJECTIVE: In this retrospective study, patient records of dogs suffering from poisoning with coumarin derivatives were evaluated to characterize the clinical appearance more precisely. MATERIAL UND METHODS: Retrospective data analysis included 52 dogs with hemostaseologically proven anticoagulant rodenticide poisoning which were treated as inpatients at the Clinic for Small Animals between September 2011 and October 2018. RESULTS: In only 2 dogs (4%) the intake of poison could be observed with certainty. The most common clinical signs observed were reduced general behavior (79%), pallor of the mucosa (79%), anorexia (60%), and dyspnea/tachypnea (60%). In contrast, macroscopically visible internal and external bleedings occurred less frequently. Initially, all cases showed a highly altered prothrombin time and most patients a considerably prolonged activated partial thromboplastin time. Anemia was present in 75% of patients. All dogs included in the study received initially an intravenous treatment with 10 mg/kg vitamin K1. Pretreatment with 1 mg/kg prednisolone was given for prophylaxis of possible incompatibility reactions. No patient showed signs of anaphylactic reaction. Transfusions of whole blood or concentrated red cells were given to only 10 of the 52 animals; only one received 2 transfusions of erythrocytes. 94% of the animals could be discharged home for outpatient therapy after a median length of hospitalization of 3 days (1-9 days) with physiological or almost physiological coagulation test results. CONCLUSION: Anticoagulant rodenticide poisoning is often associated with non-specific symptoms and good prognosis if treated adequately. CLINICAL RELEVANCE: Coagulation diagnostics is always indicated in cases with unclear disorders. In life-threatening emergencies, immediate intravenous infusion of high-dose vitamin K1 is a very effective treatment and results in a rapid increase in coagulation factor activity.

OBJECTIVE: To discuss the clinical presentation and successful treatment of a suspected case of intermediate syndrome due to organophosphate (OP) poisoning in a dog. CASE SUMMARY: Two dogs presented with acute cholinergic signs after ingesting an OP insecticide containing 50% acephate. Clinical signs consistent with acute cholinergic crisis resolved in both dogs within 24 hours postingestion. One dog developed an onset of neurological signs consistent with intermediate syndrome approximately 24 hours postingestion. This patient's clinical signs resolved with the use of pralidoxime chloride. NEW OR UNIQUE INFORMATION PROVIDED: OP poisoning most commonly presents as an acute cholinergic crisis, with rare instances of animals developing intermediate syndrome. Few reports of successful treatment and recovery from intermediate syndrome exist in the veterinary literature, particularly with instances in which 2 dogs within the same exposure setting were treated for acute cholinergic signs and only 1 progressed to an intermediate syndrome. This report also highlights the importance of early intervention with pralidoxime chloride prior to the onset of aging.

Exposure to phytotoxins that are present in imported ornamental or native plants is an important cause of animal disease. Factors such as animal behaviors (especially indoor pets), climate change, and an increase in the global market for household and ornamental plants led to the appearance of new, previously unreported plant poisonings in Europe. This has resulted in an increase in the incidence of rarely reported intoxications. This review presents some of the emerging and well-established plant species that are responsible for poisoning episodes in companion animals and livestock in Europe. The main plant species are described, and the mechanism of action of the primary active agents and their clinical effects are presented. Data reflecting the real incidence of emerging poisoning cases from plant toxins are scarce to nonexistent in most European countries due to a lack of a centralized reporting/poison control system. The diversity of plant species and phytotoxins, as well as the emerging nature of certain plant poisonings, warrant a continuous update of knowledge by veterinarians and animal owners. The taxonomy and active agents present in these plants should be communicated to ensure awareness of the risks these toxins pose for domestic animals.

Researchers have begun studying the impact of human opioid and cannabinoid use on dog populations. These studies have used data from an animal poison control center (APCC) and there are concerns that due to the illicit nature and social stigma concerning the use of these drugs, owners may not always be forthcoming with veterinarians or APCC staff regarding pet exposures to these toxicants. As a result, models derived from APCC data that examine the predictability of opioid and cannabinoid dog poisonings using pet demographic and health disorder information may help veterinarians or APCC staff more reliably identify these toxicants when examining or responding to a call concerning a dog poisoned by an unknown toxicant. The fitting of epidemiologically informed statistical models has been useful for identifying factors associated with various health conditions and as predictive tools. However, machine learning, including lasso regression, has many useful features as predictive tools, including the ability to incorporate large numbers of independent variables. Consequently, the objectives of our study were: 1) identify pet demographic and health disorders associated with opioid and cannabinoid dog poisonings using ordinary and mixed logistic regression models; and 2) compare the predictive performance of these models to analogous lasso logistic regression models. Data were obtained from reports of dog poisoning events collected by the American Society for the Prevention of Cruelty to Animals' (ASPCA) Animal Poisoning Control Center, from 2005-2014. We used ordinary and mixed logistic regression models as well as lasso logistic regression models with and without controlling for autocorrelation at the state level to train our models on half the dataset and test their predictive performance on the remainder. Although epidemiologically informed logistic regression models may require substantial knowledge of the disease systems being investigated, they had the same predictive abilities as lasso logistic regression models. All models had relatively high predictive parameters except for positive predictive values, due to the rare nature of calls concerning opioid and cannabinoid poisonings. Ordinary and mixed logistic regression models were also substantially more parsimonious than their lasso equivalents while still allowing for the epidemiological interpretation of model coefficients. Controlling for autocorrelation had little effect on the predictive performance of all models, but it did reduce the number of variables included in lasso models. Several disorder variables were associated with opioid and cannabinoid calls that were consistent with the acute effects of these toxicants. These models may help build diagnostic evidence concerning dog exposure to opioids and cannabinoids, saving time and resources when investigating these cases.

BACKGROUND: After changes in European Union biocide legislation, the Dutch Poisons Information Center observed a strong increase in information requests concerning dogs and cats exposed to α-chloralose. To investigate whether α-chloralose-based rodenticides are safe for non-professional use, additional information regarding poisoning scenarios and clinical course was collected. METHODS: Veterinarians reporting α-chloralose exposure over a 2.5-year period were contacted by mail for follow-up information concerning exposure scenario, product formulation, clinical course and treatment, and outcome. In total, information was collected for 96 dogs and 41 cats. RESULTS: Fifty-three of 96 dogs and 17 of 19 cats known to have been exposed to α-chloralose-based rodenticides developed signs of central nervous system (CNS) depression or sensory-induced CNS excitation. Mortality in dogs and cats following exposure was 1% and 18%, respectively. An additional 22 cats presented with clinical signs suggestive of α-chloralose poisoning, with a mortality of 5%. LIMITATIONS: Exposure to α-chloralose was not confirmed by biochemical analyses. CONCLUSION: Dogs and especially cats were at risk of poisoning from α-chloralose. If criteria such as acute toxicity and risk of (secondary) poisoning are applied during the approval of α-chloralose-based rodenticides, similar to anticoagulant-based rodenticides, it can be concluded that α-chloralose is also not safe for non-professional use.

This study describes the spontaneous and experimental salinomycin poisoning associated with the use of florfenicol and warns about the effects of the administration of antibiotics to animals that receive ionophores in the feed as growth promoters. A batch with 1,200 finishing pigs fed a diet containing 30ppm of salinomycin received florfenicol (60ppm via feed) to control respiratory diseases. Twenty-seven pigs had difficulty walking, tip-toe walking, muscle tremors, and anorexia seven days after the start of treatment. Twenty-two animals died, 10 recovered, and two were sent to the Laboratory of Animal Pathology of CAV-UDESC to be necropsied. The experimental reproduction of the disease was carried out to clarify the possible influence of florfenicol on salinomycin poisoning using 12 pigs divided into four groups with three animals each, treated for 16 days with diets containing no additives (Group 1), 50ppm of salinomycin (Group 2), 40ppm of florfenicol (Group 3), and 50ppm of salinomycin and 40ppm of florfenicol (Group 4). Only animals in Group 4 became ill. The clinical disease was reproduced from the ingestion of 24.67mg/kg/LW of salinomycin and 19.74mg/kg/LW of florfenicol. Both natural and experimental salinomycin poisoning associated with the use of florfenicol caused a condition of myopathy characterized in histology by hyaline degeneration and floccular necrosis of skeletal fibers, with macrophage infiltrate, associated with the figures of regeneration in skeletal muscles and multifocal areas of the proliferation of fibroblasts, being more intense in the longissimus dorsi and semimembranosus muscles. Therefore, florfenicol can cause the accumulation of ionophore salinomycin in the animal organism, resulting in a condition of toxic myopathy.
O presente trabalho descreve as intoxicações espontânea e experimental por salinomicina associada ao uso de florfenicol e alerta sobre os efeitos da administração de antibióticos aos animais que recebem ionóforos na ração como promotores de crescimento. Um lote com 1.200 suínos em fase de terminação, alimentados com ração contendo 30ppm de salinomicina, recebeu florfenicol (60ppm via ração) para o controle de doenças respiratórias. Sete dias após o início do tratamento, 27 suínos apresentaram dificuldade de locomoção, "caminhar em brasa", tremores musculares e anorexia. Vinte e dois animais morreram, 10 recuperaram-se e dois foram encaminhados ao Laboratório de Patologia Animal (CAV-UDESC) para serem necropsiados. Para esclarecer a possível influência do florfenicol na toxicidade da salinomicina foi realizada a reprodução experimental da doença utilizando 12 suínos, divididos em 4 grupos com 3 animais cada, tratados por 16 dias com rações contendo: Grupo 1 = sem aditivos, Grupo 2 = 50ppm de salinomicina, Grupo 3 = 40ppm de florfenicol e Grupo 4 = 50ppm de salinomicina e 40ppm de florfenicol. Somente os animais do Grupo 4 adoeceram. A doença clínica foi reproduzida a partir da ingestão de 24,67mg/kg/PV de salinomicina e 19,74 mg/kg/PV de florfenicol. Tanto a intoxicação natural quanto a experimental por salinomicina associada ao uso de florfenicol provocaram um quadro de miopatia caracterizado na histologia por degeneração hialina e necrose flocular das fibras esqueléticas, com infiltrado macrofágico, associada às figuras de regeneração na musculatura esquelética e áreas multifocais de proliferação de fibroblastos, sendo mais intensas nos músculos longissimus dorsi e semimembranoso. Conclui-se que, o florfenicol tem a capacidade de ocasionar o acúmulo do ionóforo salinomicina no organismo animal, resultando em um quadro de miopatia tóxica.

An epidemiological study on animal poisoning due to plants and zootoxins has been carried out by the Poison Control Centre of Milan (CAV) in collaboration with the University of Milan (Italy). During the period January 2015-March 2019, the CAV received 932 calls on animal poisonings, 12.66% (n = 118) of which were related to plants and zootoxins. Among these, 95 enquiries (80.51%) concerned exposures to plants and 23 (19.49%) to zootoxins. The dog was the species most frequently involved (67.80% of the calls, n = 80), followed by the cat (26.27%, n = 31). As for the plants, several poisoning episodes were related to glycoside-, alkaloid-, oxalate- and diterpenoid-containing species. Cycas revoluta, Euphorbia pulcherrima and Hydrangea macrophylla were the most often reported plants. The outcome has been reported for half of the episodes (51.58%, n = 49) and it was fatal for 3 animals (6.12%). Regarding the zootoxins, the majority of the enquiries were related to asp viper (Vipera aspis), but exposures to pine processionary moth (Thaumetopoea pityocampa), common toad (Bufo), fire salamander (Salamandra), and jellyfish (phylum Cnidaria) were also reported. The outcome was known in 65.22% of the cases with just one fatal episode. This epidemiological investigation depicts an interesting overview on the issue of plant and zootoxin exposures in domestic animals, highlighting the relevance of these agents as causes of animal poisoning and providing useful information for prevention and diagnosis.

This study evaluated the most common toxic agents affecting domestic cats, the clinical signs of toxicity, and the therapeutic approaches for recovery. A survey on poisoning in cats was conducted among small animal veterinary practitioners from 2017 to 2018. Of the 748 completed questionnaires, 543 (72.6%) were evaluated. Pesticides and household cleaning supplies were the most common causes of poisoning in cats. The toxicant groups included pesticides and household cleaning supplies (organophosphates), human drugs (acetaminophen), plants/plant derivatives (lily), and veterinary drugs (tramadol). The major clinical signs for these four groups of toxicants were (1) acetaminophen poisoning, which caused oxidative erythrocyte damage; (2) muscarinic and nicotinic cholinergic syndrome, which resulted from organophosphate poisoning; (3) acute kidney injury, which resulted from intoxication of lily; and (4) serotonin syndrome, which resulted from tramadol toxicosis. Interventions for treating poisoning in cats were based on the clinical presentation of animals. In the present study, the significant toxins identified to be dangerous for cats were characterized using the obtained data in Brazil as well as the main associated clinical signs and therapy recommended by veterinarians.(AU)
Objetiva-se com este trabalho caracterizar os principais toxicantes para gatos domésticos, bem como os prevalentes sinais clínicos e a terapêutica associada. Uma pesquisa sobre envenenamento em gatos foi realizada entre médicos veterinários no período de 2017 a 2018. Dos 748 questionários preenchidos, 543 (72,6%) foram avaliados. Pesticidas e domissanitários foram os principais causadores de intoxicação em gatos. Entre os grupos tóxicos, destacaram-se, na categoria pesticidas e domissanitários (organofosforados), medicamentos humanos (acetaminofeno), plantas e derivados de planta (lírio) e medicamentos veterinários (tramadol). Os principais sinais clínicos para os quatro grupos de substâncias tóxicas foram: (1) intoxicação por acetaminofeno, que causou dano eritrocitário oxidativo; (2) síndrome colinérgica muscarínica e nicotínica, resultante do envenenamento por organofosforado; (3) lesão renal aguda, causada pela intoxicação por lírio; e (4) síndrome serotoninérgica, resultante da exposição ao tramadol. As intervenções realizadas para o tratamento dos envenenamentos foram justificáveis mediante a apresentação clínica dos animais. Por meio dos dados obtidos, puderam-se caracterizar os principais tóxicos para gatos no Brasil, bem como os principais sinais clínicos associados e a terapêutica preconizada pelos médicos veterinários.(AU)

The use of pyrethroids has increased over recent years, and corresponds to a higher exposure of animals to pesticide residues in the environment and diet. Here, an outbreak of pyrethroid poisoning in beef cattle was reported occurring in Midwestern Brazil. After veterinary evaluation, it was observed that the bovines presented common pyrethroid intoxication symptoms. Aiming to identify the cattle poising by pyrethroid, earwax samples were collected from two groups: exposed and nonexposed animals from the same farm. Blind earwax analyses of the bovines were carried out using headspace/gas chromatography-mass spectrometry (HS/GC-MS). The HS/GC-MS analysis detected the presence of bifenthrin in the earwax analysis of the exposed animals, confirmed by the comparison of its MS fragments with a bifenthrin standard, and also by its retention time relative to the internal standard. In summary, HS/GC-MS analysis of earwax emerges as a tool that can be used in the detection and monitoring of bifenthrin poisoning in cattle, as a useful veterinary diagnosis that ensures animal health and the safety of their products.

OBJECTIVE: To evaluate the frequency of clinical signs, dose ingested, and outcome in a large group of dogs with bromethalin ingestion. DESIGN: Retrospective cohort study of dogs from 2010 to 2016. SETTING: Three university teaching hospitals and 1 private practice. ANIMALS: A total of 192 dogs with bromethalin ingestion. MEASUREMENTS AND MAIN RESULTS: Total 192 cases were identified, of which 25 dogs developed clinical signs. Five cases initially had severe neurological signs and were euthanized. A sum of 187 dogs survived to discharge. The total ingested dose was recorded in 59 dogs with a median (interquartile range) 0.2 mg/kg (0.28 mg/kg). The remaining 133 dogs had confirmed ingestion reported by owners (witnessed ingestion or colored feces) but the total dose could not be calculated. The median (interquartile range) time to presentation for all dogs was 2 hours (4.8 h). A majority of patients were treated on an outpatient basis (121/192) and 71 of 192 were treated as inpatients with 58 of 71 receiving fluid diuresis. Decontamination was performed in 179 dogs including emesis induction (14), activated charcoal administration (42), and both (123). Emesis was successful in 128 dogs and apomorphine was the most common emetic agent (121). Mild to severe clinical signs at admission were reported in 19 cases including vomiting (6), tremors (5), lethargy (4), ataxia (3), weakness (2), diarrhea (2), collapse (2), and and anorexia (2). One case developed ataxia and tremors within 72 hours of admission. CONCLUSIONS AND CLINICAL RELEVANCE: Symptoms of bromethalin toxicosis are uncommon, and most ingested doses are well below the reported dose expected to cause clinical signs. In this patient population, prognosis was excellent unless severe clinical signs were noted, which carried a high euthanasia rate. Effects of treatment on outcome could not be evaluated due to the low number of patients that developed clinical signs.

OBJECTIVE: To describe the clinical features, clinicopathological features, treatment, and outcome of dogs presented for albuterol exposure. DESIGN: Retrospective case series from January 2007 to December 2017. SETTING: Tertiary veterinary facility. ANIMALS: Thirty-six client-owned dogs presenting for known or suspected albuterol exposure secondary to chewing on albuterol metered-dose inhalers (MDIs). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: All dogs presented with clinical signs attributable to albuterol exposure. The most common physical examination abnormality was sinus tachycardia, noted in 34 of 36 (94%) dogs. Twenty-seven patients (75%) were admitted to the hospital for therapy, with a median length of hospitalization of 20.5 hours (16.75-24.5). Thirty-two of 36 dogs had serum electrolytes evaluated at admission, with 22 of 32 (69%) presenting with hypokalemia ([K+] < 3.62 mmol/L]). Hyperlactatemia ([lactate] > 2.80 mmol/L) was noted in 23 of 28 (82%) dogs. A negative correlation was found between serum lactate and potassium (r = -0.64, r2 = 0.40, P = 0.0003). Hyperglycemia ([glucose] > 6.44 mmol/L) was noted in 20 of 30 (67%) dogs. Beta antagonist therapy was utilized in 20 of 36 (56%) of dogs. CONCLUSIONS: Although uncommon, albuterol intoxication can lead to significant clinical and electrolyte abnormalities. Albuterol-induced hypokalemia and associated tachyarrhythmias can be successfully managed, and albuterol intoxication has an excellent prognosis for survival to discharge. A minimum database should be evaluated in all dogs presenting for suspected albuterol exposure, with lactate and glucose monitored carefully in dogs with moderate or severe hypokalemia given the correlation found.

Selenium (Se) is a metalloid that exists as a red amorphous powder, reddish crystal, silver-gray crystal, or brown-black solid. Its potency as a nutrient and a toxicant is such that few people have seen the pure element. It is easy to lose sight of the narrow margin between too little and too much. The most common cause of selenosis is accidental or intentional overuse of supplements. Many target organs and effects of Se toxicity are similar to those of Se deficiency, so laboratory confirmation is necessary. Prevention consists of minimizing exposure to seleniferous feedstuffs and optimizing dietary factors that might aggravate selenosis.

Water is the most important nutrient for rangeland livestock. However, competition with municipalities, industry, and other water users often results in grazing livestock being forced to use water supplies that are less than perfect. Surface water in western rangleands are often contaminated by mineral extraction, irrigation runoff and other human activities. Mineral contaminants in drinking water are additive with similar contaminants in feedstuffs. The goal of this and the subsequent article is to provide producers and veterinarians with the basic background to make informed decisions about whether a given water supply is "safe" for livestock.
