Sample records for acute pesticide poisoning

  1. [Acute poisoning by pesticides in children].

    Leveau, P

    2016-07-01

    Acute pesticide poisoning in children is rare but potentially serious. Some clinical patterns (toxidromes) are suggestive of the drug class: cholinergic crisis for organophosphate or carbamate insecticides; neurological syndrome for rodenticides; digestive and respiratory syndrome for herbicides. Treatment is symptomatic and only a few patients are treated with an antidote: atropine and pralidoxime for organophosphate insecticides, vitamin K for anticoagulant rodenticides. PMID:27266642

  2. Acute pesticide poisoning--a global public health problem

    Konradsen, Flemming

    2007-01-01

    Acute pesticide poisoning has become a major public health problem worldwide, following the intensification of agriculture and the promotion of agro-chemicals in low and middle income countries, with more than 300,000 deaths each year. The easy availability of highly toxic pesticides in the homes...... of farming communities has made pesticides the preferred means of suicide with an extremely high case fatality. Similarly, the extensive use of pesticides exposes the community to both long-term and acute occupational health problems. A concerted effort is urgently needed to address the situation....

    2006-01-01

    Background: Acute organophosphorus (OP) pesticide poisoning is a major clinical problem in the developing world. Textbooks ascribe most deaths to respiratory failure occurring in one of two distinct clinical syndromes - acute cholinergic respiratory failure or the intermediate syndrome. The delayed failure appears to be due to respiratory muscle weakness, but its pathophysiology is not yet clear.

    Full Text Available Organophosphates and carbamates (OPs/CMs are known for their acetylcholinesterase inhibiting character. A cross-sectional study of pesticide handling practices and self-perceived symptoms of acute pesticide poisoning was conducted using questionnaire-based interviews with 89 pesticide sprayers in Boeung Cheung Ek (BCE Lake, Phnom Penh, Cambodia. The study showed that 50% of the pesticides used belonged to WHO class I + II and personal protection among the farmers were inadequate. A majority of the farmers (88% had experienced symptoms of acute pesticide poisoning, and this was significantly associated with the number of hours spent spraying with OPs/CMs (OR = 1.14, CI 95%: 1.02–1.28. The higher educated farmers reduced their risk of poisoning by 55% for each extra personal protective measure they adapted (OR = 0.45, CI 95%: 0.22–0.91. These findings suggest that improving safe pesticide management practices among the farmers and enforcing the effective banning of the most toxic pesticides will considerably reduce the number of acute pesticide poisoning episodes.

  7. Pesticides poisoning

    Pesticides are chemical toxicants which are used to kill by their toxic actions, the pest organisms, known to incur significant economic losses or threaten human life, his health and that of his domesticated animals. These toxicants are seldom species-specific. The presence of these or their metabolites may scientific be vouched not only in the environment they are used, but in the entire ecosystem, in the subsoil, in the underwater reservoirs and in the food chain of all non-target species including man, his friends i.e. predator and parasite organisms which be uses against the pests, and in his cherished domesticated animals. In the present paper a survey is made of different groups of toxic chemicals generally used to manage pests, in the ecosystem, food chain and tissues and body parts of non-target species including man and the ones dear to him. Toxicology and biochemistry of these toxic materials and their important metabolites are also briefly discussed with special reference to ways and means through which these poison the above non-target species.

  8. Pharmacotherapy to protect the neuromuscular junction after acute organophosphorus pesticide poisoning.

    Bird, Steven B; Krajacic, Predrag; Sawamoto, Keigo; Bunya, Naofumi; Loro, Emanuele; Khurana, Tejvir S

    2016-06-01

    Organophosphorus (OP) pesticide poisoning is a leading cause of morbidity and mortality in the developing world, affecting an estimated three million people annually. Much of the morbidity is directly related to muscle weakness, which develops 1-4 days after poisoning. This muscle weakness, termed the intermediate syndrome (IMS), leads to respiratory, bulbar, and proximal limb weakness and frequently necessitates the use of mechanical ventilation. While not entirely understood, the IMS is most likely due to persistently elevated acetylcholine (ACh), which activates nicotinic ACh receptors at the neuromuscular junction (NMJ). Thus, the NMJ is potentially a target-rich area for the development of new therapies for acute OP poisoning. In this manuscript, we discuss what is known about the IMS and studies investigating the use of nicotinic ACh receptor antagonists to prevent or mitigate NMJ dysfunction after acute OP poisoning.

    2016-08-01

    Organophosphorus poisoning is a major global health problem with hundreds of thousands of deaths each year. Research interest in N-acetylcysteine has grown among increasing evidence of the role of oxidative stress in organophosphorus poisoning. We aimed to assess the safety and efficacy of N-acetylcysteine as an adjuvant treatment in patients with acute organophosphorus poisoning. This was a randomized, controlled, parallel-group trial on 30 patients suffering from acute organophosphorus poisoning, who were admitted to the Poison Control Center of Tanta University Emergency Hospital, Tanta, Egypt, between April and September 2014. Interventions included oral N-acetylcysteine (600 mg three times daily for 3 days) as an added treatment to the conventional measures versus only the conventional treatment. Outcome measures included mortality, total dose of atropine administered, duration of hospitalization and the need for ICU admission and/or mechanical ventilation. A total of 46 patients were screened and 30 were randomized. No significant difference was found between both groups regarding demographic characteristics and the nature or severity of baseline clinical manifestations. No major adverse effects to N-acetylcysteine therapy were reported. Malondialdehyde significantly decreased and reduced glutathione significantly increased only in the NAC-treated patients. The patients on NAC therapy required less atropine doses than those who received only the conventional treatment; however, the length of hospital stay showed no significant difference between both groups. The study concluded that the use of N-acetylcysteine as an added treatment was apparently safe, and it reduced atropine requirements in patients with acute organophosphorus pesticide poisoning.

    Full Text Available OBJETIVO: Describir la epidemiología de la intoxicación aguda por plaguicidas (IAP en el Hospital General O'Horán de Mérida, Yucatán, México. MATERIAL Y MÉTODOS: Se revisaron los expedientes de 33 pacientes ³ 13 años, tratados en una unidad de cuidados intensivos (UCI, entre 1994 y 1998. Se recopilaron variables demográficas y clínicas relevantes, y se aplicó estadística descriptiva. RESULTADOS: En la población estudiada predominó el sexo masculino (82% del medio rural (70%, y la edad media fue de 34 ± 15.8 años. El intento de suicidio fue causa frecuente de IAP (79%, y en 33% de los casos la intoxicación se produjo por la utilización de organofosforados. La mortalidad fue de 12%. CONCLUSIONES: La IAP fue baja entre los sujetos del medio rural, por lo que los resultados de este estudio parecen no reflejar la realidad del problema. Es importante añadir que los plaguicidas son utilizados con relativa frecuencia para el intento de suicidio.OBJECTIVE: To describe the epidemiologic pattern of acute pesticide poisoning (APP in a general hospital in Merida, Yucatan, Mexico. MATERIAL AND METHODS: From 1994 to 1998, 33 patients 13 years of age or older with diagnosis of APP were studied. Descriptive statistics were used to analyze information. RESULTS: Males were frequently affected (82%, specially those coming from rural areas (60%. The mean age of the group was 34 ± 15.8 years. In 79% of the cases, pesticides were used to commit suicide and 33% of poisoning cases were due to organophospate pesticides. The mortality rate was 12%. CONCLUSIONS: In this small sample, acute poisoning from pesticides in the agricultural setting may be underestimated, since it was less frequent than in the general population. APP was more commonly used by indigent people to commit suicide.

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

    Cao YuPing

    2006-10-01

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

  14. Relationship between Acute Organophosphorus Pesticide Poisoning and Damages Induced by Free Radicals

    2002-01-01

    Objective To study the relationship between abnormal reactions of free radicals in bodies of patients with acute organophosphorus pesticide poisoning (AOPP) and damages induced by free radicals. Methods 58 AOPP patients and 58 healthy adult volunteers (HAV) were enrolled in an independent samples control design, in which spectrophotometric methods were used to determine the concentrations of nitric oxide (NO) and lipoperoxides (LPO) in plasma, and LPO in erythrocytes, vitamin C (VC), vitamin E (VE) and b-carotene (b-CAR) in plasma as well as activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and acetylcholinesterase (AChE) in erythrocytes. Results Compared with the average values of every biochemical parameter in the HAV group, the average values of LPO in plasma and in erythrocytes, and NO in plasma in the AOPP group were significantly increased (P=0.000001), while the average values of VC, VE, a-CAR in plasma as well as SOD, CAT, GSH-Px and AChE in erythrocytes in the AOPP group were significantly decreased (P=0.000001). The findings of Pearson product-moment correlation analysis between the value of AChE in erythrocytes and the values of above biochemical parameters for 58 AOPP patients showed that there was a significant linear negative correlation between AChE in erythrocytes and LPO, NO in plasma, and LPO in erythrocytes (P=0.000001~0.001319), while there was a significant linear positive correlation between AChE in erythrocytes and VC, VE, a-CAR in plasma as well as SOD, CAT, GSH-Px in erythrocytes (P=0.000013~0.000824). The results of discriminant analysis of above chemical parameters for 58 AOPP patients and 58 HAV suggested that the correct rates of discriminant analysis were increased to 100 % when the values of AChE and LPO in plasma and in erythrocytes, or AChE and others, were jointly used for the discriminant analysis. Conclusion The findings of the present study suggest that a series of free radical

  16. Profile of acute mixed organophosphorus poisoning.

    2009-06-01

    Organophosphorus (OP) pesticide self-poisoning is a major clinical and public health problem across much of rural Asia and responsible for two thirds of suicidal deaths. However, clinical reports or evidence for the management of mixed poisoning are lacking. Patients are often treated based on the type of symptoms they exhibit, and there are no specific guidelines available to treat mixed poisoning. In this case series, we report 3 acute OP poisoning cases with mixed poisons such as organochlorine, fungicide, copper sulfate, and kerosene. All 3 patients were treated successfully, with a greater focus on OP poisoning with pralidoxime and atropine infusion along with standard decontamination procedures. Because patients developed complications due to the concomitant poisons ingested, they were later treated symptomatically, and in one case, D-penicillamine was administered as antidote for copper poisoning. Mixed poisoning especially with OP compounds makes the diagnosis difficult because the clinical symptoms of OP predominate, whereas damage produced by other pesticides is late to develop and often neglected. Common treatment procedures are focused mainly on the OP poisoning ignoring the complications of other concomitant pesticides ingested. Treating physicians should be prepared and consider the possibility of mixed poisoning prevalent in that region before initiating therapy. PMID:19497478

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

    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.

  4. Searching for the universal reactivator for treatment of pesticide poisoning

    According to the present knowledge, none of the currently available oximes (pralidoxime, obidoxime, trimedoxime, MMB-4 or HI-6) originally developed for the treatment of the nerve agent poisonings is able to treat organophosphorus pesticide poisoning. Among them, obidoxime seems to be the best candidate, however, its high toxicity disfavors its application in the high quantities. As byproduct of our searching for the new nerve agent reactivators, we found that oxime K027 seems to be very promising in the case of the treatment of organophosphorus pesticide poisonings. Its reactivation potency is similar or better than that of obidoxime, and moreover, its acute toxicity is lower. Thanks to these results, this oxime seems to be the best candidate for future use as universal reactivator for the treatment of poisonings caused by organophosphorus pesticides.

  6. Massive acute arsenic poisonings.

    Lech, Teresa; Trela, Franciszek

    2005-07-16

    Arsenic poisonings are still important in the field of toxicology, though they are not as frequent as about 20-30 years ago. In this paper, the arsenic concentrations in ante- and post-mortem materials, and also forensic and anatomo-pathological aspects in three cases of massive acute poisoning with arsenic(III) oxide (two of them with unexplained criminalistic background, in which arsenic was taken for amphetamine and one suicide), are presented. Ante-mortem blood and urine arsenic concentrations ranged from 2.3 to 6.7 microg/ml, respectively. Post-mortem tissue total arsenic concentrations were also detected in large concentrations. In case 3, the contents of the duodenum contained as much as 30.1% arsenic(III) oxide. The high concentrations of arsenic detected in blood and tissues in all presented cases are particularly noteworthy in that they are very rarely detected at these concentrations in fatal arsenic poisonings.

  8. Determinants of lethality from suicidal pesticide poisoning in metropolitan HsinChu.

    Sheu, J J; Wang, J D; Wu, Y K

    1998-12-01

    Acute pesticide poisoning is a global health problem, especially in developing countries. Although Taiwan has quickly industrialized during the last several decades, pesticide use is still prevalent in the agricultural sector. We reviewed 187 consecutive hospitalized cases of the Provincial HsinChu Hospital from January 1989 through December 1995 to explore the determinants of acute pesticide poisoning in Metropolitan HsinChu. The annual incidence rate of acute pesticide poisoning was 3.2/100,000 with an overall fatality rate of 23% which was more severe than the rates found in developed countries. The major agents involved were organophosphates, and the major cause of poisoning was suicide. Alcohol abuse, history of major medical illnesses, and history of suicide were significantly associated with suicidal poisoning; quarrel was the immediate risk factor. Causes of poisoning (suicide vs non-suicide) and selection of the pesticides were major determinants of lethality. More stringent legislation and enforcement regarding the sale and distribution of extremely toxic pesticides are needed to reduce fatalities due to acute pesticide poisoning. PMID:9830692

  14. Neurology of acute organophosphate poisoning

    Singh Gagandeep

    2009-01-01

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

  15. Correlation between Cholinesterase and Paraoxonase 1 Activities: Case Series of Pesticide Poisoning Subjects

    S Austin Richard

    2013-08-01

    Full Text Available Introduction: Acute exposure to pesticide due to suicidal poisoning is the most extensive cause of pesticide exposure, compared with all other causes including agricultural or industrial exposure. Organophosphate (OP and carbamate group of pesticides can inhibit acetylcholinesterase; on the other hand, paraoxonase1 can detoxify organophosphate poisoning by hydrolyzing organophosphate metabolites. Methods: We have compared the serum paraoxonase1 status and cholinesterase activity of subjects who attempted to commit suicide by consuming OP pesticide. Cholinesterase and paraoxonase1 activity were measured spectrophotometrically using butyrylthiocholine and phenyl acetate as substrates, respectively. Results: A positive correlation was found between serum paraoxonase1 activity and cholinesterase activity among pesticide consumed subjects. Conclusion: Our results suggest that subjects with higher paraoxonase1 activity may have a better chance of detoxifying the lethal effect of acute organophosphate poisoning.

  15. Pesticide poisoning in the developing world--a minimum pesticides list

    Eddleston, Michael; Karalliedde, Lakshman; Buckley, Nick;

    2002-01-01

    In parts of the developing world, pesticide poisoning causes more deaths than infectious diseases. Use of pesticides is poorly regulated and often dangerous; their easy availability also makes them a popular method of self-harm. In 1985, the UN Food and Agriculture Organisation (FAO) produced a...... voluntary code of conduct for the pesticide industry in an attempt to limit the harmful effects of pesticides. Unfortunately, a lack of adequate government resources in the developing world makes this code ineffective, and thousands of deaths continue today. WHO has recommended that access to highly toxic...... pesticides be restricted--where this has been done, suicide rates have fallen. Since an Essential Drugs List was established in 1977, use of a few essential drugs has rationalised drug use in many regions. An analogous Minimum Pesticides List would identify a restricted number of less dangerous pesticides to...

  16. Pattern of pesticide storage before pesticide self-poisoning in rural Sri Lanka

    Eddleston Michael

    2009-11-01

    Full Text Available Abstract Background Deliberate self-poisoning with agricultural pesticides is the commonest means of suicide in rural Asia. It is mostly impulsive and facilitated by easy access to pesticides. The aim of this large observational study was to investigate the immediate source of pesticides used for self-harm to help inform suicide prevention strategies such as reducing domestic access to pesticides. Methods The study was conducted in a district hospital serving an agricultural region of Sri Lanka. Patients who had self-poisoned with pesticides and were admitted to the adult medical wards were interviewed by study doctors following initial resuscitation to identify the source of pesticides they have ingested. Results Of the 669 patients included in the analysis, 425 (63.5% were male; the median age was 26 (IQR 20-36. In 511 (76% cases, the pesticides had been stored either inside or immediately outside the house; among this group only eight patients obtained pesticides that were kept in a locked container. Ten percent (n = 67 of the patients used pesticides stored in the field while 14% (n = 91 purchased pesticides from shops within a few hours of the episode. The most common reasons for choosing the particular pesticide for self-harm were its easy accessibility (n = 311, 46% or its popularity as a suicide agent in their village (n = 290, 43%. Conclusion Three quarters of people who ingested pesticides in acts of self-harm used products that were available within the home or in close proximity; relatively few patients purchased the pesticide for the act. The study highlights the importance of reducing the accessibility of toxic pesticides in the domestic environment.

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

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

    2010-09-01

    This descriptive and retrospective study was conducted at the poisoning ward of Imam teaching hospital, Sari, Iran, with the aim of evaluating the pattern of poisoning. Hence, the medical profiles of 2057 patients, who were admitted, were carefully reviewed during the period from April 2006 to March 2008 for 2 years. During this period, 2057 cases, 53.9% female and 46.1% male, were admitted with the indication of acute poisoning. The greatest proportion of poisoning occurred between the ages of 18 and 29 years, with suicidal intentions. Most cases of poisoning were intentional (85%). The most common agents involved in acute poisoning were drugs (77.7%), especially sedatives/hypnotics such as benzodiazepines, followed by opioid analgesics. Organophosphate and carbamate insecticides were the third major agent that induced poisoning. Twenty-seven patients (1.3%) who were mostly females and young adults died. Death mostly occurred due to organophosphate and carbamate insecticides (19 cases) poisoning, followed by sedatives/hypnotics like benzodiazepines (3 cases). High prevalence of intentional overdose and mortality among young adults requires considerable attention and further studies to find out the underlying causes. In addition, strict rules must be followed regarding the sale of central nervous system drugs and pesticides, particularly organophosphate and carbamate insecticides. Establishing poison information centers in different parts of the country, preparing national treatment guidelines, training healthcare providers, and ensuring easy availability of the antidotes are also recommended.

    2014-07-01

    We report a case of 30 year old alcoholic male admitted with vomiting, drowsiness, limb weakness and fasciculations after alleged history of consumption of 30 ml of chlorpyriphos insecticide. He had low serum cholinesterase levels. With standard treatment for organophosphorus poisoning (OPP), he improved gradually until day 5, when he developed neck and limb weakness and respiratory distress. This intermediate syndrome was treated with oximes, atropine and artificial ventilation. During treatment, his ECG showed fresh changes of ST elevation. High CPK & CPK-MB levels, septal hypokinesia on 2D echo suggested acute coronary syndrome. Coronary angiography was postponed due to his bedridden and obtunded status. The patient finally recovered fully by day 15 and was discharged. Acute coronary syndrome is a rare occurrence in OP poisoning. The present case thus emphasises the need for careful electrocardiographic and enzymatic monitoring of all patients of organophosphorus poisoning to prevent potential cardiac complication which can prove fatal.

    2012-05-01

    Full Text Available Acute poisonings are a frequent complaint in emergency departments and therapy which prevents the absorption of toxic products taken orally is often indicated: one such option is gastric lavage. Gastric lavage is a digestive decontamination technique whose goal is to remove the maximum amount of poison from the stomach and prevent its absorption. The procedure involves inserting a gastric tube into the stomach through the mouth or nose; firstly to aspirate all the stomach contents and then to perform gastric washing manoeuvres. The effectiveness of gastric lavage is limited and involves a risk of iatrogenesis, and therefore the indications and contraindications should be carefully considered and the technique carried out meticulously to increase its effectiveness and reduce complications, primarily bronchoaspiration. Gastric lavage may be used in conjunction with other digestive decontamination techniques such as administration of activated charcoal. This gastric lavage protocol is based on a review of the literature on this procedure and is supported by the expertise of our research group in gastrointestinal decontamination techniques in patients with acute poisoning.

  7. Acute aluminium phosphide poisoning, what is new?

    Yatendra Singh

    2014-01-01

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

    A 3-year-old boy had persistent cortical blindness following acute carbon monoxide poisoning. He was believed to have suffered anoxic brain damage due to incomplete combustion of the briquette-type solid fuel. Computed tomographic (CT) scan of the brain and visual evoked potentials (VEP) in the early stage were normal. However, on the 20th hospital day CT scan showed leukomalacia and VEP showed an absence of N1-, and P1-waves which was well correlated with the clinical feature at that time. PMID:4083389

    Of the more than 5000 species of mushrooms known, 100 types are toxic and approximately 10% of these toxic types can cause fatal toxicity. A type of mushroom called Amanita phalloides is responsible for 95% of toxic mushroom poisonings. In this article, we report 2 cases of mushroom poisonings caused by Lactarius volemus, known as Tirmit by the local people. The patient and his wife were admitted to the emergency room with abdominal pain, nausea, and vomiting 20 hours after consuming Lactarius volemus, an edible type of mushroom. The patients reported that they had been collecting this mushroom from the mountains and eating them for several years but had never developed any clinicopathology to date. Further examination of the patients revealed a very rare case of acute pancreatitis due to mushroom intoxication. The male patient was admitted to the intensive care unit while his wife was followed in the internal medicine service, because of her relative mild clinical symptoms. Both patients recovered without sequelae and were discharged. In this article, we aimed to emphasize that gastrointestinal symptoms are often observed in mushroom intoxications and can be confused with acute pancreatitis, thus leading to misdiagnosis of patients. Early diagnosis and appropriate treatment can improve patients’ prognosis and prevent the development of complications. PMID:26835473

    Paraquat is a highly effective contact herbicide that is marketed worldwide as a fantastical, non-selective compound for broadleaf weed control. As compared to most pesticides, paraquat is extremely toxic to humans and the lack of strategies to manage paraquat poisoning has resulted in high fatality rates. The rats were randomly divided into acute paraquat poisoning group and control group. The paraquat group rats were given 36 mg/kg paraquat by intragastric administration. The influence of acute paraquat poisoning on the activities of CYP450 isoforms CYP2B6, CYP1A2, CYP2C9, CYP2D6, CYP3A4 and CYP2C19 were evaluated by cocktail method, they were responded by the changes of pharmacokinetic parameters of bupropion, phenacetin, tolbutamide, metoprolol, midazolam and omeprazole. The six probe drugs were given to rats through intragastric administration, and the plasma concentrations were determined by UPLC-MS/MS. In the results of paraquat group compared to control group, there was statistical pharmacokinetic difference for bupropion, tolbutamide, metoprolol, midazolam and omeprazole. Acute paraquat poisoning may induce the activities of CYP2C19, and inhibit of CYP2B6, CYP2C9, CYP2D6 and CYP3A4 in rats. This may give advising for reasonable drug use after acute paraquat poisoning.

  15. Community uptake of safe storage boxes to reduce self-poisoning from pesticides in rural Sri Lanka

    van der Hoek Wim

    2007-01-01

    Full Text Available Abstract Background Acute poisoning by agricultural pesticides is a well established global public health problem. Keeping pesticides under safe storage is now promoted as a potential way to reduce the number of severe poisoning cases. However, there have been no published studies documenting the feasibility of such an approach. Therefore, the objective of the study presented here was to determine community perceptions and use of in-house safe storage boxes for pesticides in rural Sri Lanka. Methods Boxes with a lock, to be used for the in-house safe storage of pesticides, were distributed to 200 randomly selected farming households in two agricultural communities. A baseline survey determined pesticide storage practices and household characteristics prior to distribution. The selected households were encouraged to make use of the box at community meetings and during a single visit to each household one month after distribution. No further encouragement was offered. A follow-up survey assessed storage practices seven months into the project. Results Following the distribution of the boxes the community identified a number of benefits including the protection of pesticide containers against exposure from the rain and sun and a reduced risk of theft. Data were analysed for 172 households that reported agricultural use of pesticides at follow-up. Of these, 141 (82% kept pesticides in the house under lock against 3 (2% at baseline. As expected, the distribution of boxes significantly reduced the number of households storing pesticides in the field, from 79 (46% at baseline to 4 (2% at follow-up. There was a significant increase in the number of households keeping pesticides safe from children between baseline (64% and seven months after the distribution of boxes (89%. The same was true for adults although less pronounced with 51% at baseline and 66% at follow-up. Conclusion The farming community appreciated the storage boxes and made storage of

  19. Acute carbon monoxide poisoning alters hemorheological parameters in human.

    Ozturk, Baris; Arihan, Okan; Coskun, Figen; Dikmenoglu-Falkmarken, Neslihan H

    2016-01-01

    Acute carbon monoxide (CO) poisoning seriously hinders oxygen delivery to tissues. This harmful effect of CO may be aggravated by accompanying changes in the viscosity of blood. We had previously reported increased plasma viscosity in people chronically exposed to CO. This study was planned to test our hypothesis that acute CO poisoning increases blood viscosity. For this purpose four main parameters contributing to blood viscosity - hematocrit, erythrocyte deformability, erythrocyte aggregation and plasma viscosity - were determined in patients with acute CO poisoning and compared with healthy controls. Plasma viscosity and erythrocyte aggregation tendency were lower in the CO group (p <  0.05). Erythrocyte deformability was also lower in CO group (p <  0.05). Our results indicate that acute CO poisoning has diverse effects on hemorheological parameters such as attenuating hematocrit value, plasma viscosity, erythrocyte aggregation tendency and erythrocyte deformability.

  20. Acute human self-poisoning with imidacloprid compound: a neonicotinoid insecticide.

    Fahim Mohamed

    Full Text Available BACKGROUND: Deliberate self-poisoning with older pesticides such as organophosphorus compounds are commonly fatal and a serious public health problem in the developing world. The clinical consequences of self-poisoning with newer pesticides are not well described. Such information may help to improve clinical management and inform pesticide regulators of their relative toxicity. This study reports the clinical outcomes and toxicokinetics of the neonicotinoid insecticide imidacloprid following acute self-poisoning in humans. METHODOLOGY/PRINCIPAL FINDINGS: Demographic and clinical data were prospectively recorded in patients with imidacloprid exposure in three hospitals in Sri Lanka. Blood samples were collected when possible for quantification of imidacloprid concentration. There were 68 patients (61 self-ingestions and 7 dermal exposures with exposure to imidacloprid. Of the self-poisoning patients, the median time to presentation was 4 hours (IQR 2.3-6.0 and median amount ingested was 15 mL (IQR 10-50 mL. Most patients only developed mild symptoms such as nausea, vomiting, headache and diarrhoea. One patient developed respiratory failure needing mechanical ventilation while another was admitted to intensive care due to prolonged sedation. There were no deaths. Median admission imidacloprid concentration was 10.58 ng/L; IQR: 3.84-15.58 ng/L, Range: 0.02-51.25 ng/L. Changes in the concentration of imidacloprid in serial blood samples were consistent with prolonged absorption and/or saturable elimination. CONCLUSIONS: Imidacloprid generally demonstrates low human lethality even in large ingestions. Respiratory failure and reduced level of consciousness were the most serious complications, but these were uncommon. Substitution of imidacloprid for organophosphorus compounds in areas where the incidence of self-poisoning is high may help reduce deaths from self-poisoning.

    Objective: To assess the emergency care outcomes of acute chemical poisoning cases in tertiary care settings in Rawalpindi, Pakistan. Methods: The data were extracted from an injury surveillance study conducted in the emergency departments (ED) of three tertiary care hospitals of Rawalpindi city from July 2007 to June 2008. The World Health Organization standard reporting questionnaire (one page) was used for recording information. Associations of patients' characteristics with ED care outcomes, i.e., admitted vs. discharged were assessed using logistic regression models. Results: Of 62 530 injury cases reported, chemical poisoning was identified in 434 (0.7%) cases. The most frequent patient characteristics were poisoning at home (61.9%), male gender (58.6%), involving self-harm (46.0%), and youth aged 20–29 years (43.3%). Over two-thirds of acute poisoning cases (69.0%) were admitted. Acute poisoning cases were more likely to be admitted if they were youth aged 10–19 years [odds ratio (OR)=4.41], when the poisoning occurred at home (OR=21.84), and was related to self-harm (OR=18.73) or assault (OR=7.56). Conclusions: Findings suggest that controlling access of poisonous substances in youth and at homes might reduce related ED care burden. Safety promotion agencies and emergency physicians can use these findings to develop safety messages.

    2007-12-01

    Full Text Available Abstract Background Evidence is accumulating that pesticide self-poisoning is one of the most commonly used methods of suicide worldwide, but the magnitude of the problem and the global distribution of these deaths is unknown. Methods We have systematically reviewed the worldwide literature to estimate the number of pesticide suicides in each of the World Health Organisation's six regions and the global burden of fatal self-poisoning with pesticides. We used the following data sources: Medline, EMBASE and psycINFO (1990–2007, papers cited in publications retrieved, the worldwide web (using Google and our personal collections of papers and books. Our aim was to identify papers enabling us to estimate the proportion of a country's suicides due to pesticide self-poisoning. Results We conservatively estimate that there are 258,234 (plausible range 233,997 to 325,907 deaths from pesticide self-poisoning worldwide each year, accounting for 30% (range 27% to 37% of suicides globally. Official data from India probably underestimate the incidence of suicides; applying evidence-based corrections to India's official data, our estimate for world suicides using pesticides increases to 371,594 (range 347,357 to 439,267. The proportion of all suicides using pesticides varies from 4% in the European Region to over 50% in the Western Pacific Region but this proportion is not concordant with the volume of pesticides sold in each region; it is the pattern of pesticide use and the toxicity of the products, not the quantity used, that influences the likelihood they will be used in acts of fatal self-harm. Conclusion Pesticide self-poisoning accounts for about one-third of the world's suicides. Epidemiological and toxicological data suggest that many of these deaths might be prevented if (a the use of pesticides most toxic to humans was restricted, (b pesticides could be safely stored in rural communities, and (c the accessibility and quality of care for poisoning

    2014-11-01

    Full Text Available : OBJECTIVES: To determine the common agents, clinical features and outcomes of acute poisoning. MATERIALS AND METHODS: A retrospective study of patients of acute poisoning of more than 14 years age admitted through emergency with a history of intentional, self-inflicted and suicidal poisoning in SRMS-IMS from Jan 2010 to Dec 2012. RESULTS: A total of 58 cases were included with a common age of affection 16 to 25 years and male to female ratio 1.63: 1. Poisoning cases occur throughout the year with maximum prevalence in May and minimum in June. Organophosphorus was the most common poison followed by aluminium phosphide. Vomiting was the most common symptoms followed by altered sensorium. 70.68% patients were discharged, 20.68% expired and 8.62% left against medical advice. Aluminium phosphide was the most common toxin consumed by dead patients. CONCLUSION: Acute poisoning is commonly affecting young population and is caused by variety of toxin. High mortality is associated with aluminum phosphide.

    Full Text Available Context We report a case of massive poisoning with meprobamate leading to acute pancreatitis. Case report A 43-year-old patient with a history of schizophrenia and multiple suicide attempts was admitted to the intensive care unit for severe poisoning with meprobamate (voluntary ingestion of 60 g. On admission, the patient was deeply comatose with low blood pressure and hypothermia. Laboratory analysis revealed leukocytosis and high lipase and amylase serum levels. There was no eosinophilia. Abdominal computed tomography showed pancreatitis grade A. The patient was intubated and ventilated, and intravenous dopamine was infused. The patient regained consciousness and was extubated five days later. Improvement in pancreatic tests was noted several days later. The outcome was favorable. Discussion According to the Naranjo probability scale, meprobamate-induced acute pancreatitis was probable. Acute pancreatitis in meprobamate poisoning is exceptional. The pathogenesis of pancreatitis-induced meprobamate poisoning may be explained by two mechanisms: stimulation of pancreatic secretion secondary to cholinergic activation and pancreatic ductal hypertension. Conclusions The signs of severe meprobamate toxicity are numerous including cardiovascular and central nervous symptoms. Acute pancreatitis should also be added as a possible manifestation of meprobamate poisoning.

    Full Text Available Abstract Background Poisoned patients are often treated in and discharged from pre-hospital health care settings. Studies of poisonings should therefore not only include hospitalized patients. Aims: To describe the acutely poisoned patients treated by ambulance personnel and in an outpatient clinic; compare patients transferred to a higher treatment level with those discharged without transfer; and study the one-week mortality after pre-hospital discharge. Methods A one-year multi-centre study with prospective inclusion of all acutely poisoned patients ≥ 16 years of age treated in ambulances, an outpatient clinic, and hospitals in Oslo. Results A total of 3757 health service contacts from 2997 poisoning episodes were recorded: 1860 were treated in ambulances, of which 15 died and 750 (40% were discharged without transfer; 956 were treated in outpatient clinic, of which 801 (84% were discharged without transfer; and 941 episodes were treated in hospitals. Patients discharged alive after ambulance treatment were mainly poisoned by opiates (70%, were frequently comatose (35%, had respiratory depression (37%, and many received naloxone (49%. The majority of the patients discharged from the outpatient clinic were poisoned by ethanol (55%, fewer were comatose (10%, and they rarely had respiratory depression (4%. Among the hospitalized, pharmaceutical poisonings were most common (58%, 23% were comatose, and 7% had respiratory depression. Male patients comprised 69% of the pre-hospital discharges, but only 46% of the hospitalized patients. Except for one patient, who died of a new heroin overdose two days following discharge from an ambulance, there were no deaths during the first week after the poisonings in the 90% of the pre-hospital discharged patients with known identity. Conclusion More than half of the poisoned patients treated in pre-hospital treatment settings were discharged without transfer to higher levels. These poisonings were more often

    or by their chemical family (organochlorates, organophosphates, carbamates, pyrethroids, Bipyridilium compounds, inorganic salts…. All of them are biocides, which normally implies a high toxicity for humans, which has been a cause for concern since the mid-XX century due to the widespread and indiscriminate use of these products. Exposure to pesticides can have effects that are acute, chronic and long-term. Some organochlorate compounds (such as DDT were the first to be used in massive fumigations to fight malaria and have had to be banned because of their capacity for bioaccumulation and environmental persistence. The danger represented by the widespread presence of these agents has been demonstrated in numerous episodes of human toxic epidemics, producers of a high morbidity/mortality, described for nearly all chemical families: organochlorate insecticides and fungicides, organophosphate and carbamate insecticides, organomercurial fungicides and inorganic salts. These episodes have above all been caused through the ingestion of foodstuffs and in the occupational field. Other causes of health concern are their carcinogenic capacity and occasional reproductive alterations. The principal characteristics of some of the most relevant families are presented.

    Mary Kasule

    2009-04-01

    Full Text Available Background: This study sought to characterise acute poisoning cases seen in three health districts of Botswana.Method: A retrospective review of patients’ records was conducted and included patients treated from January 2004 to December 2005. Data on the demographic status of the patients, information about the poisonous agent(s involved, and the circumstances and outcomes of the poisoning incidents were recorded on a pre-tested data collection form.Results: A total of 590 cases of acute poisoning were included in the analysis. The most affected age category was that of children aged less than six years, who constituted 33.4% of the cases. Most incidents were recorded in the urban district of Gaborone. Seventy-eight percent (78% of the incidents were accidental, with the remainder being intentional. The poisonous agents involved were pharmaceuticals (26.6%, natural toxins (25.6%, household products (14.6%, foods (14.4%, alcohol (6.9%, traditional medicines (4.7%, unspecified agents (3.2%, and agrochemicals (2.7%. The most common route of poison exposure was by oral (82.2%, followed by dermal contact (16.5%, while the inhalation of gases occurred in 1.2% of cases. An incidence rate of 4.7/1000, a case fatality rate of 3.8/100, and 1.5% of deaths were recorded over the two-year period.Conclusion: In conclusion, it can be stated that acute poisoning involved mainly young children and resulted in an incidence rate of 4.7/1000, a case fatality rate of 3.8/100, and 1.5% of deaths over the two-year period. There were differences based on age category, gender and residence of the victims, the types of toxic agents involved, as well as the circumstances and the outcomes of the poisoning incidents. Given the fact that pharmaceuticals, natural toxins, household products and foods were the agents most commonly involved, targeted interventions should take these differences into account in addressing the problem of acute poisoning.

    2010-03-01

    Full Text Available Abstract Background Mercury poisoning can occur as a result of occupational hazard or suicide attempt. This article presents a 36-year-old case admitted to emergency department (ED due to exposure to metallic mercury. Case Presentatıon A 36-year-old woman presented to the ED with a three-day history of abdominal pain, diarrhea and fever. One week ago her daughter had brought mercury in the liquid form from the school. She had put it on the heating stove. One day later, her 14-month old sister baby got fever and died before admission to the hospital. Her blood pressure was 134/87 mmHg; temperature, 40.2°C; heart rate 105 bpm and regular; respiration, 18 bpm; O2 saturation, 96%. Nothing was remarkable on examination and routine laboratory tests. As serine or urinary mercury levels could not be tested in the city, symptomatic chelation treatment with N-acetyl cysteine (NAC was instituted with regard to presumptive diagnosis and history. At the 7th day of admission she was discharged without any sequelae or complaint. At the discharge day blood was drawn and sent for mercury levels which turned out to be 30 μg/dL (normal range: 0 - 10 μg/dL. Conclusion Public education on poisoning and the potential hazards of mercury are of vital importance for community health.

    2004-09-01

    We describe a case of refractory status epilepticus presenting to a rural general hospital in Sri Lanka. This patient's condition was precipitated by intentional self-poisoning with the organochlorine insecticide endosulfan. Although rarely seen in developed countries, pesticide poisoning particularly with endosulfan is an important cause of difficult-to-manage seizures in Asian countries. In this case report, we discuss the management of status epilepticus and refractory status epilepticus. Further, we specifically discuss the clinical pharmacology and toxicology of endosulfan.

    2014-03-01

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

  4. Acute Toxicity of Four Organophosphorus Pesticide Products

    2012-01-01

    Acute toxicity of phoxim,acephate,isofenphos-methyl and isocarbophos on male SD rats of clean grade was carried out by gastric lavage method at room temperature of 18℃. These rats are 4 to 5 months old with body weight of 180 to 220 kg. The results indicate that the orders of the toxicity of these four pesticides on SD rats are isofenphos-methyl,isocarbophos,acephate,phoxim. We found that the median lethal concentration of phoxim in 24 h,48 h,72 h and 96 h is 3. 892 g /kg,3. 051 g /kg,2. 618 g /kg and 2. 458 g /kg respectively; the median lethal concentration of isofenphos-methyl in 24 h,48 h,72 h and 96 h is 0. 015 g /kg,0. 013g /kg,0. 012g /kg and 0. 011 g /kg respectively; the median lethal concentration of isocarbophos in 24 h,48 h,72 h and 96 h is 0. 049 g /kg,0. 046 g /kg,0. 043 g /kg,0. 041 g /kg respectively; and the median lethal concentration of acephate in 24 h,48 h,72 h and 96 h is 0. 137 g /kg,0. 113 g /kg,0. 100 g /kg,0. 085 g /kg respectively. Finally,we evaluated the characteristics of toxicity effect and safe concentration of these pesticides to SD rats.

    2014-01-01

    Full Text Available Background: Organophosphorus poisoning remains an important cause of morbidity and mortality, but no definite parameters have been identified as predictors of outcome. Prediction of morbidity at presentation might help in decision making in places of limited resources like rural settings in developing countries. Materials and Methods: A total of 76 cases were included in this retrospective cohort study. Logged relative risk of requirement of mechanical ventilation and hospital stay >7 days was measured in patients with serum acetylcholinesterase (s. acetylcholinesterase 1000, presenting in 12 and in patients with SpO 2 7 days. Conclusion: S. acetylcholinesterase, SpO 2 at room air, GCS, and duration of exposure at presentation can be used to identify the requirement of special care in acute organophosphorus poisoning. This can aid in decision making regarding admission to intensive care unit and referral in the places with limited resources.

    Abu Saleh Ahmed

    2014-03-01

    Full Text Available Background:Acute poisoning with organophosphorus (OP pesticides is a common method of suicide and entails considerable mortality in Bangladesh. The objective of this study was to evaluate the effects and outcomes of a protocol for treatment of OP poisoning that included titrated incremental atropine as loading dose and slow infusion for maintenance.  Methods:In this prospective descriptive case series, definitive OP poisoned patients were enrolled in an adult medicine unit of Dhaka Medical College Hospital from April 2006 to April 2007. Clinical examinations were done as soon as the patient entered the ward. Patient’s demographics, comorbid conditions and the occurrence of specific clinical outcomes including death, need for assisted ventilation and clinical complications were recorded. The patients were treated according to the protocol. Results: A total of 56 patients were enrolled over the study period. The median age of the study population was 22.5 years. Most patients were men (67.8%. The most common clinical presentation was miosis (58.9%. In total, 11 patients died (19.6%. Intermediate syndrome developed in 12 patients (21.4% and 6 of them died. Assisted ventilation was required in 16 cases (28.5. Patients with diastolic blood pressure ≤ 70 mmHg and/or GCS ≤ 10 were significantly less likely to survive (P = 0.02, 0.006, respectively. Moreover, early respiratory failure (P < 0.001 and the need for assisted ventilation (P < 0.001 were significantly higher among deceased cases. The mortality rate in this study was similar to previous studies. The frequency of atropine toxicity in the present study (1.8% was considerably lower than conventional regimen used in previous studies. Conclusion:Using the new protocol, lower rate of atropine toxicity developed in victims. Hence, the new protocol appears to be safer and its effectiveness should be further evaluated in case control studies in Bangladesh.    How to cite this article: Ahmed AS

Kidney function recovered with supportive care. Nephrotoxic mushroom poisoning should be considered as a cause of acute kidney i...

  11. CT of the brain in acute carbon monoxide poisoning

    Cerebral computed tomographic (CT) findings of acute carbon monoxide (Co) poisoning were analized in thirty-six cases treated with hyperbraric oxygen therapy and their relationship with prognosis was evaluated. The cases were classified into there groups, early stage, interval form, and non-interval form groups. In all groups, the initial abnormality was low density areas presumably due to edema, demyelination and/or softening. It was seen in the globus pallidus and/or white matter. Following these initial changes, cerebral hemorrhage, ventricular dilatation, and cerebral atrophy developed in a few cases. The frequency of abnormal CT findings was higher in the interval form group (85 %) or non-interval group (83 %) than the early stage group (41 %). The prognosis was good in most cases with normal CT findings. The possibility of recovery diminished in the patients with abnormal CT findings. The prognosis was particularly poor in cases showing abnormality both in globus pallidus and white matter. We conclude that CT is useful not only for detecting the pathologic change but also for predicting the prognosis of the patient with acute Co poisoning. (author)

    Full Text Available Background : Aluminum phosphide (AlP is used as a fumigant. It produces phosphine gas, which is a mitochondrial poison. Unfortunately, there is no known antidote for AlP intoxication, and also, there are few data about its prognostic factors. AIMS: The aim of this study was to determine the impact of the Simplified Acute Physiology Score II (SAPS II in the prediction of outcome in patients with acute AlP poisoning requiring admission to the Intensive Care Unit (ICU. Materials and Methods : This was a prospective study in patients with acute AlP poisoning, admitted to the ICU over a period of 12 months. The demographic data were collected and SAPSII was recorded. The patients were divided into survival and non-survival groups due to outcome. Statistical Analysis : The data were expressed as mean ± SD for continuous or discrete variables and as frequency and percentage for categorical variables. The results were compared between the two groups using SPSS software. Results : During the study period, 39 subjects were admitted to the ICU with acute AlP poisoning. All 39 patients required endotracheal intubation and mechanical ventilation in addition to gastric decontamination with sodium bicarbonate, permanganate potassium, and activated charcoal, therapy with MgSO 4 and calcium gluconate and adequate hydration. Among these patients, 26 (66.7% died. SAPSII was significantly higher in the non-survival group than in the survival group (11.88 ± 4.22 vs. 4.31 ± 2.06, respectively (P < 0.001. Conclusion : SAPSII calculated within the first 24 hours was recognized as a good prognostic indicator among patients with acute AlP poisoning requiring ICU admission.

    2012-01-01

    Full Text Available Introduction. Caffeine is indicated in the treatment of migraine headaches, as well as neonatal apnea and bradycardia syndrome. In mild poisoning, the most prevalent symptoms are nausea, vomiting, diarrhea, tremor, anxiety and headache. In more severe cases, symptoms consist of heart rythym abnormalities, myocardial infarction and seizures. Due to its common lipolytic effect, caffeine is used in mesotherapy, usually in combination with drugs of similar effect. We presented a patient with acute iatrogenic caffeine poisoning. Case report. A 51-year-old woman, with preexisting hypertension and hypertensive cardiomyopathy was subjected to cosmetic treatment in order to remove fat by intradermal caffeine injections. During the treatment the patient felt sickness, an urge to vomit, and a pronounced deterioration of general condition. Upon examination, the patient exhibited somnolence, hypotension and nonsustained ventricular tachycardia, which was sufficient enough evidence for further hospitalization. On admission to the intensive care unit the patient was anxious with increased heart rate, normotensive, with cold, damp skin, and visible traces of injection sites with surrounding hematomas on the anterior abdominal wall. Paroxysmal supraventricular tachycardia (PSVT on electrocardiographic monitoring was found. The laboratory analysis determined a lowered potassium level of 2.1 mmol/L (normal range 3,5 - 5.2 mmol/L, and a toxicological analysis (liquid chromatography with ultraviolet detection proved a toxic concentration of caffeine in plasma - 85.03 mg/L (toxic concentration over 25 mg/L. On application of intensive therapy, antiarrhythmics, and substitution of potassium, as well as both symptomatic and supportive therapy, there was a significant recovery. The patient was discharged without any sequele within four days. Conclusion. A presented rare iatrogenic acute caffeine poisoning occured due to massive absorption of caffeine from the

    2012-07-01

    Aluminium phosphide (AlP) poisoning has a high mortality due to cardiovascular involvement. In this study, we evaluated the frequency of cardiac manifestations and electrocardiographic (ECG) findings in 20 patients with acute AlP poisoning, who were admitted to the intensive care unit (ICU) in Tehran, Iran, over a period of 6 months (between October 2008 and April 2009). The sex, age, cause and manner of ingestion, number of ingested AlP tablets, cardiac and ECG manifestations, creatine phosphokinase (CPK), CPK-myocardial band (CPK-mb) and troponin-T (TnT) were extracted from the patients' files. All data were analysed with Statistical Package for the Social Sciences (SPSS) software. The majority (60%) of patients were male. The mean age was 27 ± 8.7 years. The mortality rate was 40%. In all of the patients, the cause of poisoning was intentional suicide and ingestion was the route of exposure. The mean number of ingested AlP tablets per patient was 2.2 ± 1.1. The average time interval between admission and cardiovascular manifestations or ECG findings was 168.8 ± 116.2 min. The range of systolic (SBP) and diastolic blood pressure was 60-130 mmHg and 40-70 mmHg, respectively. Dysrhythmia was observed in nine (45%) cases. Elevation of the ST segment was seen in nine cases (45%). Seven patients (35%) had prolonged QTc intervals. Bundle branch block (BBB) was observed in four (20%) patients. In nine (45%) patients, the serum cardiac TnT qualitative assay was positive. There were no significant differences between normal and abnormal ECG groups according to sex, age, number and manner of ingested AlP tablets and SBP. There was a significant correlation between cardiac manifestations and ECG findings and TnT-positive results with mortality in acute AlP poisoning. PMID:22687771

  17. Poisoning of raptors with organophosphorus and carbamate pesticides with emphasis on Canada, U.S. and U.K.

    We reviewed cases of raptor mortality resulting from cholinesterase-inhibiting pesticides. We compiled records from the U.S., U.K. and Canada for the period 1985-95 (520 incidents) and surveyed the relevant literature to identify the main routes of exposure and those products that led to the greatest number of poisoning cases. A high proportion of cases in the U.K. resulted from abusive uses of pesticides (willful poisoning). The proportion was smaller in North America where problems with labeled uses of pesticides were as frequent as abuse cases. Poisoning resulting from labeled use was possible with a large number of granular pesticides and some seed treatments through secondary poisoning or through the ingestion of contaminated invertebrates, notably earthworms. With the more toxic products, residue levels in freshly-sprayed insects were high enough to cause mortality. The use of organophosphorus products as avicides and for the topical treatment of livestock appeared to be common routes of intoxication. The use of insecticides in dormant oils also gave rise to exposure that can be lethal or which can debilitate birds and increase their vulnerability. A few pesticides of high toxicity were responsible for the bulk of poisoning cases. Based on limited information, raptors appeared to be more sensitive than other bird species to organophosphorus and carbamate pesticides. Some of the more significant risk factors that resulted in raptor poisonings were: insectivory and vermivory; opportunistic taking of debilitated prey; scavenging, especially if the gastrointestinal tracts are consumed; presence in agricultural areas; perceived status as pest species; and flocking or other gregarious behavior at some part of their life cycle. Lethal or sublethal poisoning should always be considered in the diagnosis of dead or debilitated raptors even when another diagnosis (e.g., electrocution, car or building strike) is apparent. Many cases of poisoning are not currently

  19. Brain CT scan in acute carbon monoxide poisoning

    The brain CT findings in 19 patients with acute carbon monoxide poisoning was analysed and the emphasis was placed on the relationship between CT findings and prognosis. Five had a normal manifestation in CT ; eight had the findings of ovoid or patchy low density area in globus pallidus, bilateral or unlateral, during the second day to fifth week after poisoning, and the low density areas were decreasing and blurring in edge in follow up and at last disappeared during 3 - 14 weeks in three cases of them ; nine showed the appearance of diffuse low density of white matter and of globus pallidus in some of them ; two had an appearance of brain atrophy. The pathology of CT findings mentioned above may be brain edema, necrosis, malacia and degeneration in gray matter and globus pallidus. The result suggested the cases with normal CT manifestation, cerebral edema and decreasing and disappearing low density area had a good prognosis, in contrary, the cases with persistant low density in globus pallidus had a poorer prognosis.

  20. Pesticides and children

    Prevention and control of damage to health, crops, and property by insects, fungi, and noxious weeds are the major goals of pesticide applications. As with use of any biologically active agent, pesticides have unwanted side-effects. In this review, we will examine the thesis that adverse pesticide effects are more likely to occur in children who are at special developmental and behavioral risk. Children's exposures to pesticides in the rural and urban settings and differences in their exposure patterns are discussed. The relative frequency of pesticide poisoning in children is examined. In this connection, most reported acute pesticide poisonings occur in children younger than age 5. The possible epidemiological relationships between parental pesticide use or exposure and the risk of adverse reproductive outcomes and childhood cancer are discussed. The level of consensus among these studies is examined. Current concerns regarding neurobehavioral toxicity and endocrine disruption in juxtaposition to the relative paucity of toxicant mechanism-based studies of children are explored

    WANG Qiwei; HUANG Xiaojiang; LIU Liang

    2007-01-01

    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.

  8. Acute poisoning with clenbuterol--a case report.

    Chodorowski, Z; Sein Anand, J

    1997-01-01

    In the paper we have described a case of acute, unintentional intoxication with clenbuterol, a selective beta 2-agonist. A 21-year-old bodybuilder to improve his physical fitness and to increase his muscle bulk was using clenbuterol in a dose of two tablets (20 mg) daily for a week before poisoning. On a day of acute intoxication he drank orange juice containing 48 tablets (4.8 g) of clenbuterol, which had been placed there by his friends. The patient was admitted to our clinic with tachycardia at rate 160 bpm, headache, dizziness, tremor, sweats, muscle weakness, agitation. Serum potassium concentration was 2.6 mmol/L, blood glucose level 18.7 mmol/L. All the symptoms and biochemical abnormalities disappeared after intravenous treatment with propranolol (1.0 mg) and potassium chloride (60 mmol) within five hour period. This case indicates that more attention should be paid to clenbuterol widely used as a stimulant by athletes, especially by bodybuilders. PMID:9478104

  13. Neurological Effects of Acute Carbon Monoxide Poisoning in Children

    Coskun YARAR

    2009-11-01

    Full Text Available Carbon monoxide poisoning (COP is one of the most common causes of mortality and morbidity due to poisoning in all over the world. Although the incidence of COP has not been known exactly in the childhood, almost one-third of CO exposures occurred in children. The data regarding COP in children are inconclusive. Children may be more vulnerable to CO exposure than adults as a result of their high respiration and metabolic rates, high oxygen metabolism, and immature central nervous system. Recent researches proposed new theories about neurological effects of CO toxicity. The clinical presentations associated acute COP may be various and nonspecific. Unrecognized CO exposure may lead to significant morbidity and mortality. CO exposed children often become symptomatic earlier, and recover more rapidly, than similarly CO exposed adults. Mild clinical signs and symptoms associated with COP are headache, dizziness, weakness, lethargy, and myalgia; however, severe signs and symptoms such as blurred vision, syncope, convulsion, coma, cardiopulmonary arrest and death can also accompany with COP. Neurologic manifestations can include altered mental status at different degrees, neck stiffness, tremor, ataxia, and positive Babinski's sign. Delayed neurologic sequels (DNS of COP might be seen in children like adults. DNS symptoms and signs in children include memory problems, mental retardation, mutism, fecal and urinary incontinence, motor deficits, facial palsy, psychosis, chronic headache, seizures, and epilepsy. After CO exposure children must be cared to detect and treat DNS. Although hyperbaric oxygen therapy (HBOT is reported to prevent development of DNS, its indications, application duration and procedures are controversial in both of the children and adults. Although their predictive values are limited, exposing to CO more than eight hours and suffering from CO-induced coma, cardiac arrest, lactic acidosis, high COHb levels, and pathologic findings

    The purpose of the study was to define characteristics of children with acute carbon monoxide poisoning. Eighty children hospitalized with acute carbon monoxide poisoning were recruited prospectively over a period of 12 months. Sociodemographic features, complaints and laboratory data were recorded. When the patient was discharged, necessary preventive measures to be taken were explained to parents. One month later, the parents were questioned during a control examination regarding the precautions that they took. The ages of the cases were between one month and 16 yr. Education levels were low in 86.2% of mothers and 52.6% of fathers. All families had low income and 48.8% did not have formal housing. The source of the acute carbon monoxide poisoning was stoves in 71.2% of cases and hot-water heaters in 28.8% of cases. Three or more people were poisoned at home in 85.1% of the cases. The most frequent symptoms of poisoning were headache and vertigo (58.8%). Median carboxyhemoglobin levels at admission to the hospital and discharge were measured as 19.5% and 1.1% (P carbon monoxide poisoning are usually from families with low socioeconomic and education levels. Education about prevention should be provided to all people who are at risk of carbon monoxide poisoning before a poisoning incident occurs. PMID:26713060

    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 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. This non-conventional practice is not recommended. PMID:26717371

  16. Edaravone attenuates brain damage in rats after acute CO poisoning through inhibiting apoptosis and oxidative stress.

    2016-03-01

    Acute carbon monoxide (CO) poisoning is the most common cause of death from poisoning all over the world and may result in neuropathologic and neurophysiologic changes. Acute brain damage and delayed encephalopathy are the most serious complication, yet their pathogenesis is poorly understood. The present study aimed to evaluate the neuroprotective effects of Edaravone against apoptosis and oxidative stress after acute CO poisoning. The rat model of CO poisoning was established in a hyperbaric oxygen chamber by exposed to CO. Ultrastructure changes were observed by transmission electron microscopy (TEM). TUNEL stain was used to assess apoptosis. Immunohistochemistry and immunofluorescence double stain were used to evaluate the expression levels of heme oxygenase-1 (HO-1) and nuclear factor erythroid 2-related factor 2 (Nrf-2) protein and their relationship. By dynamically monitored the carboxyhemoglobin (HbCO) level in blood, we successfully established rat model of severe CO poisoning. Ultrastructure changes, including chromatin condensation, cytoplasm dissolution, vacuoles formation, nucleus membrane and cell organelles decomposition, could be observed after CO poisoning. Edaravone could improve the ultrastructure damage. CO poisoning could induce apoptosis. Apoptotic cells were widely distributed in cortex, striatum and hippocampus. Edaravone treatment attenuated neuronal apoptosis as compared with the poisoning group (P < 0.01). Basal expressions of HO-1 and Nrf-2 proteins were found in normal brain tissue. CO poisoning could activate HO-1/Nrf-2 pathway, start oxidative stress response. After the administration of Edaravone, the expression of HO-1 and Nrf-2 significantly increased (P < 0.01). These findings suggest that Edaravone may inhibit apoptosis, activate the Keapl-Nrf/ARE pathway, and thus improve the ultrastructure damage and neurophysiologic changes following acute CO poisoning. © 2014 Wiley Periodicals, Inc.

  17. Successful Treatment of Acute Lethal Dose of Acrylamide Poisoning

    Ali Banagozar Mohammadi

    2015-03-01

    Full Text Available Background: Acrylamide (C3H5NO is a vinyl monomer. This water-soluble crystalline solid is a colorless, odorless agent which is used in scientific laboratories and some industries. Acrylamide has cellular oxidative effects. Acute or chronic poisoning with this agent happens as a result of skin, respiratory, or oral contacts. Clinical manifestations depend on the dose, duration, and frequency of contact. Management of these patients consists of conservative and palliative therapies to reduce the oxidative effects. Case: The case was a 29-year-old girl with a Master of Sciences degree in genetics who worked in a university research center with previous history of depression. She had ingested 100cc of 30% Acrylamide solution for intentional suicide attempt. The patient was successfully managed using N-acetyl cysteine, vitamin C, and melatonin. Conclusion: Early diagnosis and appropriate treatment with recommended agents together with supportive therapies can save the life of patients exposed to potentially lethal doses of acrylamide, although intentional or accidental.

  19. Salvianolic Acids Attenuate Rat Hippocampal Injury after Acute CO Poisoning by Improving Blood Flow Properties

    Li Guan

    2015-01-01

    Full Text Available Carbon monoxide (CO poisoning causes the major injury and death due to poisoning worldwide. The most severe damage via CO poisoning is brain injury and mortality. Delayed encephalopathy after acute CO poisoning (DEACMP occurs in forty percent of the survivors of acute CO exposure. But the pathological cause for DEACMP is not well understood. And the corresponding therapy is not well developed. In order to investigate the effects of salvianolic acid (SA on brain injury caused by CO exposure from the view point of hemorheology, we employed a rat model and studied the dynamic of blood changes in the hemorheological and coagulative properties over acute CO exposure. Compared with the groups of CO and 20% mannitol + CO treatments, the severe hippocampal injury caused by acute CO exposure was prevented by SA treatment. These protective effects were associated with the retaining level of hematocrit (Hct, plasma viscosity, fibrinogen, whole blood viscosities and malondialdehyde (MDA levels in red blood cells (RBCs. These results indicated that SA treatment could significantly improve the deformation of erythrocytes and prevent the damage caused by CO poisoning. Meanwhile, hemorheological indexes are good indicators for monitoring the pathological dynamic after acute CO poisoning.

Pesticide self-poisoning is a major public health and clinical problem in rural Asia, where it has led to case fatality ratios 20-30 times higher than self-poisoning in the developed world. One approach to reducing access to pesticides is for households to store pesticides in lockable "safe-storage" containers. However, before this approach can be promoted, evidence is required on its effectiveness and safety. Methods/Design A community-based cluster randomised controlled trial has been set up in 44,000 households in the North Central Province, Sri Lanka. A census is being performed, collecting baseline demographic data, socio-economic status, pesticide usage, self-harm and alcohol. Participating villages are then randomised and eligible households in the intervention arm given a lockable safe storage container for agrochemicals. The primary outcome will be incidence of pesticide self-poisoning over three years amongst individuals aged 14 years and over. 217,944 person years of follow-up are required in each arm to detect a 33% reduction in pesticide self-poisoning with 80% power at the 5% significance level. Secondary outcomes will include the incidence of all pesticide poisoning and total self-harm. Discussion This paper describes a large effectiveness study of a community intervention to reduce the burden of intentional poisoning in rural Sri Lanka. The study builds on a strong partnership between provincial health services, local and international researchers, and local communities. We discuss issues in relation to randomisation and contamination, engaging control villages, the intervention, and strategies to improve adherence.

    Mercury is a toxic heavy metal and occurs in organic and inorganic forms. Inorganic mercury includes elemental mercury and mercury salts. Mercury salts are usually white powder or crystals, and widely used in indigenous medicines and folk remedies in Asia. Inorganic mercury poisoning causes acute kidney injury (AKI) and gastrointestinal manifestations and can be life-threatening. We describe a case with unknown substance poisoning who developed AKI and disseminated intravascular coagulation (...

    Carbon monoxide poisoning, a public health problem of considerable significance, is a relatively frequent event today, resulting in thousands of hospitalizations annually. A 70-year-old lady was seen in the emergency department with a provisional diagnosis of carbon monoxide poisoning. The previous night, she slept in a tightly closed room heated with coal ember. She was found unconscious in the morning with poor ventilation. She had a rare presentation of popliteal vein thrombosis, pulmonary emboli, and possible tissue necrosis with carbon monoxide poisoning. Oxygen treatment with low-molecular-weight heparin (nadroparine) and warfarin therapy resulted in an improvement in both popliteal and pulmonary circulations. In conclusion, the presence of pulmonary emboli should be sought in patients with carbon monoxide poisoning.

Sixteen cases were treated during this period at the University of Mississippi Medical Center and 6 received Hyperbaric Oxygen therapy. These 6 cases and the mechanisms of CO poisoning are discussed and recommendations for emergency management are reviewed.10 references.

  6. Profile of acute carbon monoxide poisoning in the west province of Iran

    Objective: To document the epidemiology and risk factors of acute carbon monoxide (CO) poisoning in the west of Iran and specify potentially presentable characteristics. Study Design: Observational study. Place and Duration of Study: Imam Khomeini Hospital of Kermanshah, Iran, from July 2006 to March 2008. Methodology: This study was conducted using the records of 143 cases of CO poisoning referred to the only centre for the reference of poisoning cases. Intent, age groups, source of poisoning and clinical presentation were noted and described as frequency. Results: One-hundred forty two cases (99.3%), were accidental and only one case (0.7%) was suicidal. Mortality was (21.7%, n=31). The highest mortality was found in the age groups of 20-30 years and below 10 years. The greatest frequency happened in autumn and winter. The clinical symptoms and manifestations of CO poisoning included headache (35.3%), nausea (25.4%), vomiting (21%), dyspnea (10.3%), and decrease in level of consciousness (8%). Gas water heaters (35%), room heaters (32%), stoves (24%) and other items (9%) were the principal sources of the individuals' exposure to CO. Conclusion: CO poisoning is a serious public health problem in west of Iran (Kermanshah). The number of CO poisoning cases was highest in the colder seasons of the year, whereas the majority of the poisoning cases could be prevented. (author)

    Poisoning represents one of the most common medical emergencies in childhood, and epidemiological properties differ from country to country. Thus, special epidemiological surveillance for each country is necessary to determine the problem according to which preventive measures can be taken. The purpose of this study was to clarify the characteristics of acute poisoning cases admitted to a pediatric referral hospital. All poisoned patients under 17 years of age, except for cases food poisoning, presenting to the Emergency Department (ED) from January 1995 to December 2000 were determined. The information about each case was recorded on standardized forms and a retrospective chart review survey was done. Complete epidemiological and clinical data were obtained for 489 patients. The mean age of all poisoned patients (mean +/- standard deviation) was 5.96 +/- 4.87 years, and the age range was 0.01 to 17 years. Three hundred and thirty-one children, forming 63.6% of all patients, were under five years of age. Slightly more boys (52.3%) than girls were intoxicated at ages less than 10 years, after which more girls (79%) than boys were involved. The majority of all cases were due to accidental poisoning (78.1% of all poisonings) which occurred mostly in children under five years of age (73.3%). While accidental poisonings (97.1%) were the most common mode of poisoning between 1-5 years, self-poisonings (67.3%) had the highest ratio in cases over 10 years of age. In patients younger than one year of age, 74.2% of all poisonings were due to therapeutical error. Drugs were the most frequent offending agent (57.7%), followed by ingestion of a caustic/corrosive substance (16.8%) and carbon monoxide (CO) intoxication (9.4%). Analgesics were the most common agents, forming 23.7% of all poisonings due to drugs, followed by ingestion of multiple drugs and tricyclic antidepressants at ratios of 21.6% and 9.6%, respectively. The most common route of poisoning was ingestion of the

  8. Pesticide exposure in children.

    2012-12-01

    This statement presents the position of the American Academy of Pediatrics on pesticides. Pesticides are a collective term for chemicals intended to kill unwanted insects, plants, molds, and rodents. Children encounter pesticides daily and have unique susceptibilities to their potential toxicity. Acute poisoning risks are clear, and understanding of chronic health implications from both acute and chronic exposure are emerging. Epidemiologic evidence demonstrates associations between early life exposure to pesticides and pediatric cancers, decreased cognitive function, and behavioral problems. Related animal toxicology studies provide supportive biological plausibility for these findings. Recognizing and reducing problematic exposures will require attention to current inadequacies in medical training, public health tracking, and regulatory action on pesticides. Ongoing research describing toxicologic vulnerabilities and exposure factors across the life span are needed to inform regulatory needs and appropriate interventions. Policies that promote integrated pest management, comprehensive pesticide labeling, and marketing practices that incorporate child health considerations will enhance safe use. PMID:23184103

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

  10. Impact of chronic and acute pesticide exposures on periphyton communities

    Aquatic ecosystems face variable exposure to pesticides, especially during floodings which are associated with short bursts of high contaminant concentrations that influence biological systems. A study was undertaken to highlight the impact of the herbicide diuron applied in mixture with the fungicide tebuconazole on natural periphyton during flooding events. Periphyton were grown in two series of two lotic outdoor mesocosms: one series was non-contaminated while the other was exposed to chronic contamination. After 4 weeks, one channel of each series was exposed to three successive pulses, with each pulse followed by one week of recovery. Impacts on periphyton were assessed by using Denaturing Gel Gradient Electrophoresis to characterize eukaryotic community structure. At a functional scale, photosynthetic efficiency was quantified during each pulse, and the induced tolerance to diuron was estimated by performing short-term inhibition tests based on photosynthetic efficiency. Moreover, pesticide concentrations in the water column and periphyton matrix were measured. Diuron was adsorbed in the periphyton during each pulse and desorbed 13 h after pulse end. The different pulses affected the eukaryotic community structures of the control biofilms, but not of the chronically exposed ones. During the first pulse, photosynthetic efficiency was correlated with pesticide concentration in the water phase, and there was no difference between periphyton from chronically contaminated channels and control channels. However, during the second and third pulses, the photosynthetic efficiency of periphyton chronically exposed to pesticides appeared to be less impacted by the acute pulsed exposure of pesticide. These changes were consistent with the acquisition of induced tolerance to diuron since only after the third pulse that periphyton from chronic channel became tolerant to diuron. Our experimental study indicates that the effects of pulsed acute exposures to pesticides on

    Full Text Available Background: Poisoning is one of the important reasons for children’s admission to hospital. Knowledge of epidemiology of poisoning in each region plays an important role in planning prevention, care, and treatment of patients. This study was conducted to determine the characteristics of acute poisoning epidemiology in children attending pediatric wards of Amirkabir Hospital in Arak in a five-year period (March 2008 to March 2012. Methods: This descriptive cross-sectional study was conducted on 224 children admitted for poisoning. Data were retrospectively collected from patients’ files and analyzed using SPSS 16 software. Results: Of the total population, 54.9% were boys and the rest were girls. Mean age of children was 3.54±2.99 years, and the most common age range was 1-3 years (50.9%. The highest rate of children’s admission due to poisoning was in the winter (30.8%. The most common causes of poisoning included drugs (65.2%, kerosene (7.1%, and food poisoning (5.4%. The most common poisoning drugs, included benzodiazepines (21.9%, gastrointestinal drugs (19.9%, opioid analgesics (15.1%. The most prevalent drugs were methadone, metoclopramide, and clonazepam. At admission, the most common presenting symptoms were neurological (51.3%, and gastrointestinal symptoms (38.4%. Conclusion: High prevalence of poisoning with groups of drugs mentioned could indicate community-wide excessive use of these drugs, as well as negligence of families in keeping them out of children’s reach. Therefore, raising knowledge and awareness about variety of poisoning and how to prevent them, through holding workshops, national media, schools, and health centers can be a valuable step toward upkeep of children’s health.

    BACKGROUND: Health effects of pesticides are easily diagnosed when acute poisonings occurs, nevertheless, consequences from chronic exposure can only be observed when neuropsychiatric, neurodegenerative or oncologic pathologies appear. Therefore, early monitoring of this type of exposure is especially relevant to avoid the consequences of pathologies previously described; especially concerning workers exposed to pesticides on the job. For acute organophosphate pesticides (OPP) exposure, two b...

  15. ACUTE ACCIDENTAL POISONING IN CHILDREN: A HOSPITAL-BASED RETROSPECTIVE STUDY

    Kameshore

    2014-10-01

    Full Text Available INTRODUCTION: Acute accidental poisoning in children is a big problem anywhere in the world. Studies done elsewhere in India showed a wide range of incidence of the problem. Hence, it was felt important to study its magnitude and associated characteristics as of now. OBJECTIVE: The current study was taken up to know the magnitude among children admitted in JNIMS, Imphal which is a newly established medical institute and also to study the characteristics like age, gender, type of poison, duration of hospital-stay and outcome of the cases. MATERIALS & METHODS: Retrospective data of all acute accidental poisoning cases among children admitted in the Pediatrics Ward, JNIMS, Imphal during the period July 2008 - December 2013 were analyzed by using descriptive statistics. RESULT: Of all the 13,663 children admitted, 148 cases were because of acute accidental poisoning giving an incidence rate of 1.08%. The male is to female ratio was 1.31:1. The last three years of the study period showed a slightly increasing trend in the incidence. Children aged 1-4 years were the most commonly affected (65.54%. Kerosene oil was by far the commonest (42% of all the poisonous substances consumed. Food poisoning, poisoning with organic compounds, poisoning with medicinal drugs and poisoning with corrosives comprised 21%, 12%, 9% and 8% respectively of all the cases. There was no mortality. DISCUSSION: The incidence rate of 1.08% as found out from the current study was on the lower side as compared to reports of previous studies done in other parts of the country. Yet, it was two-fold of the incidence reported from RIMS which is situated in the same State. Parental negligence in storing poisonous substances in the household was implicated. They need to be made aware for keeping harmful poisonous substances in safe places out of the reach of children. CONCLUSION: Community-based studies are recommended for estimating more accurately the magnitude of the problem in the

    Mushroom exposures are increasing worldwide. The incidence and fatality of mushroom poisoning are reported to be increasing. Several new syndromes in mushroom poisoning have been described. Rhabdomyolytic mushroom poisoning is one of new syndromes. Russula subnigricans mushroom can cause delayed-onset rhabdomyolysis with acute kidney injury in the severely poisoned patient. There are few reports on the toxicity of R. subnigricans. This report represents the first record of R. subnigricans poisoning with rhabdomyolysis in Korea, describing a 51-year-old man who suffered from rhabdomyolysis, acute kidney injury, severe hypocalcemia, respiratory failure, ventricular tachycardia, cardiogenic shock, and death. Mushroom poisoning should be considered in the evaluation of rhabdomyolysis of unknown cause. Furthermore, R. subnigricans should be considered in the mushroom poisoning with rhabdomyolysis.

    Carbon monoxide (CO) is the leading cause of death due to poisoning. Although uncommon, CO poisoning does occur during pregnancy and can result in fetal mortality and neurological malformations in fetuses who survive to term. Uncertainty arises regarding the use of hyperbaric oxygen (HBO) as a treatment for the pregnant patient because of possible adverse effects on the fetus that could be induced by oxygen at high partial pressures. While the dangers of hyperoxia to the fetus have been demonstrated in animal models, careful review of animal studies and human clinical experience indicates that the short duration of hyperoxic exposure attained during HBO therapy for CO poisoning can be tolerated by the fetus in all stages of pregnancy and reduces the risk of death or deformity to the mother and fetus. A case is presented of acute CO poisoning during pregnancy that was successfully treated with HBO. Recommendations are suggested for the use of HBO during pregnancy.

    A method for the determination of 200 pesticides and pesticide metabolites in honeybee samples has been developed and validated. Almost 98% of compounds included in this method are approved to use within European Union, as active substances of plant protection products or veterinary medicinal products used by beekeepers to control mites Varroa destructor in hives. Many significant metabolites, like metabolites of imidacloprid, thiacloprid, fipronil, methiocarb and amitraz, are also possible to detect. The sample preparation was based on the buffered QuEChERS method. Samples of bees were extracted with acetonitrile containing 1% acetic acid and then subjected to clean-up by dispersive solid phase extraction (dSPE) using a new Z-Sep+ sorbent and PSA. The majority of pesticides, including neonicotionoids and their metabolites, were analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS) but some of pesticides, especially pyrethroid insecticides, were analyzed by gas chromatography tandem mass spectrometry (GC-MS/MS). The procedure was validated according to the Guidance document SANCO/12571/2013 at four concentration levels: 1, 5, 10 and 100 ng/g bees and verified in the international proficiency test. The analysis of bee samples spiked at the limit of quantification (LOQ) showed about 98% mean recovery value (trueness) and 97% of analytes showed recovery in the required range of 70-120% and RSDr (precision) below 20%. Linearity and matrix effects were also established. The LOQs of pesticides were in the range of 1-100 ng/g. The developed method allows determination of insecticides at concentrations of 10 ng/g or less, except abamectin and tebufenozide. LOQ values are lower than the median lethal doses LD50 for bees. The method was used to investigate more than 70 honeybee poisoning incidents. Data about detected pesticides and their metabolites are included. PMID:26830634

    Full Text Available Hydrogen sulfide (H2S is the second leading cause of toxin related death (after carbon monoxide in the workplace. H2S is absorbed by the upper respiratory tract mucosa, and it causes histotoxic hypoxemia and respiratory depression. Cocktail method was used to evaluate the influences of acute H2S poisoning on the activities of cytochrome P450 isoforms CYP2B6, CYP2D6, CYP3A4, CYP1A2, CYP2C19, and CYP2C9, which were reflected by the changes of pharmacokinetic parameters of six specific probe drugs, bupropion, metoprolol, midazolam, phenacetin, omeprazole, and tolbutamide, respectively. The experimental rats were randomly divided into two groups, control group and acute H2S poisoning group (inhaling 300 ppm for 2 h. The mixture of six probes was given to rats by oral administration and the blood samples were obtained at a series of time points through the caudal vein. The concentrations of probe drugs in rat plasma were measured by LC-MS. The results for acute H2S poisoning and control groups were as follows: there was a statistically significant difference in the AUC and Cmax for bupropion, metoprolol, phenacetin, and tolbutamide, while there was no statistical pharmacokinetic difference for midazolam and omeprazole. Acute H2S poisoning could inhibit the activity of CYP2B6, CYP2D6, CYP1A2, and CYP2C9 in rats.

  2. Oral administration of lactulose: a novel therapy for acute carbon monoxide poisoning via increasing intestinal hydrogen production.

    Fan, Dan-Feng; Hu, Hui-Jun; Sun, Xue-Jun; Meng, Xiang-En; Zhang, Yu; Pan, Shu-Yi

    2016-01-01

    It has been known that the pathophysiology of carbon monoxide (CO) poisoning is related to hypoxia, the increased production of reactive oxygen species (ROS) and oxidative stress. Studies have shown that the novel, safe and effective free radical scavenger, hydrogen, has neuroprotective effects in both acute CO poisoning and delayed neuropsychological sequelae in CO poisoning. Orally administered lactulose, which may be used by some intestinal bacteria as a food source to produce endogenous hydrogen, can ameliorate oxidative stress. Based on the available findings, we hypothesize that oral administration of lactulose may be a novel therapy for acute CO poisoning via increasing intestinal hydrogen production. PMID:27000012

Results A total of 2298 patients were reported from 2006 to 2009.Among them, the incidence of occupational poisoing accounted for 25.59% (588 cases), including 4 fatalities (fatality rate, 0.68% ). Male patients (458 cases, 77.89% ) were more than femal ones ( 130 cases, 22.11% ) in occupational pesticides poisoning. Summer and autumn were the most seasons in occupational pesticides poisoning occurring. The incidence of non-occupational pesticides poisoning accounted for 74.41% ( 1710 cases ),including 112 fatalities (fatality rate, 6.55%). Femal patients (952 cases, 55.67% ) were more than male ones (758 cases, 44.33% ) in non-occupational pesticides poisoning. 15-55 years were the highest incidences among non-occupational pesticides poisoning patients. Insecticides especially organophosphorus insecticides such as methamidophos, parathion, and omethoate comprised a higher proportion, accounting for 79.98% of the pesticides poisoning. Conclusion The incidence and the fatality rate of occupational pesticide poisoning were reduced in the city. However, more attention should be paied to non-occupational pesticides poisoning. To decrease the numbers of pesticide poisoning and the risks of death, the relevant departments should take preventive strategy and measures against the pesticide poisoning.%目的 了解湖州市农药中毒的危害现状,为农药中毒预防控制提供依据.方法 将2006至2009年每年应用"中国疾病预防控制信息系统"的子系统"健康危害因素检测信息系统"所建立的农药中毒报告数据库导入Excel,进行汇总统计,使用SPSS 12.0软件进行统计分析.结果 2006至2009

In mild poisoning, the most prevalent symptoms are nausea, vomiting, diarrhea, tremor, anxiety and headache. In more severe cases, symptoms consist of heart rythym abnormalities, myocardial infarction and seizures. Due to its common lipolytic effect, caffeine is used in mesotherapy, usually in combination with drugs of similar effect. We presented a patient wit...

  5. The Acute Oral Toxicity of Commonly Used Pesticides in Iran, to Honeybees (Apis Mellifera Meda

    Rasuli Farhang

    2015-06-01

    Full Text Available The honey bee is credited with approximately 85% of the pollinating activity necessary to supply about one-third of the world’s food supply. Well over 50 major crops depend on these insects for pollination. The crops produce more abundantly when honey bees are plentiful. Worker bees are the ones primarily affected by pesticides. Poisoning symptoms can vary depending on the developmental stage of the individual bee, and the kind of chemical employed. The oral toxicity of these insecticides: (phosalone and pirimicarb, acaricide (propargite, insecticide and acaricide (fenpropathrin, fungicides, and bactericides (copper oxychloride and the Bordeaux mixture, were evaluated for the purposes of this research. The results showed that fenpropathrin had high acute oral toxicity (LC50-24h and LC50-48 were 0.54 and 0.3 ppm, respectively. Propargite had 7785 ppm (active ingredient for LC50-24h and 6736 ppm (active ingredient for LC50-48h in honeybees and is therefore, non-toxic to Apis mellifera. On the other hand, copper oxychloride had minimum acute oral toxicity to honeybees (LC50-24h and LC50-48 were 4591.5 and 5407.9 ppm, respectively and was therefore considered non-toxic. Also, the Bordeaux mixture was safe to use around honeybees. Phosalone and primicarb were considered highly and moderately toxic to honeybees, respectively.

    Objective:To understand the distribution features and economic losses of the hospitalized children with acute poisoning, scientific basis was provided to prevent and control the acute poisoning in children.Methods:A retrospective analysis of 38 cases of acute poisoning in children admitted to the pediatric in Heji Hospital affiliated to Changzhi Medical College from 2007 to 2012.Results:In the children with poisoning,25 cases were male,while 13 caseswere female.Children were divided into four groups according to the age:<1,1~4,5~9,and 10~14,whose distribution were respectively 6 cases,20 cases,4 cases,8 cases.Rural and urban poisoning proportion was 1.38:1.The peak was in September and the indoor poisoning accounted for 86.84%.34.21% poisoning was caused by the drug in acute poisoning,while the same with the chemical poisoning.The economic losses of acute poisoning caused by pesticide was(5 171.03 ±4 843.46)RMB on average,which was the highest.The economic losses caused by plant was (2 062.63±715.78)RMB on average, which was the second highest.Conclusion:The number of male children with acute poisoning in the hospital were larger than the female, and mainly concentrated in 1~4 years old,who lived in rural rather than the city.In addition,drug poisoning was the main type of acute poisoning.Pesticide poisoning made the largest economic loss.Measures should be taken to prevent and control the acute poisoning according to its epidemiological characteristics.%目的:了解急性中毒住院患儿的分布特征和经济损失,为儿童急性中毒的预防、控制提供科学依据。方法:回顾性分析38例儿童急性中毒病例。结果:38例中毒患儿中,男25例,女13例;<1岁、1~4岁、5~9岁、10~14岁年龄组分别为6、20、4、8例;农村、城市中毒比例1.38∶1;9月份为发病高峰期;发生在户内占86.84%。急性中毒中药物中毒和化学性中毒各占34.21%。急性中毒的经济损失

  7. Does the clock make the poison? Circadian variation in response to pesticides.

    Louisa A Hooven

    Full Text Available BACKGROUND: Circadian clocks govern daily physiological and molecular rhythms, and putative rhythms in expression of xenobiotic metabolizing (XM genes have been described in both insects and mammals. Such rhythms could have important consequences for outcomes of chemical exposures at different times of day. To determine whether reported XM gene expression rhythms result in functional rhythms, we examined daily profiles of enzyme activity and dose responses to the pesticides propoxur, deltamethrin, fipronil, and malathion. METHODOLOGY/PRINCIPAL FINDINGS: Published microarray expression data were examined for temporal patterns. Male Drosophila were collected for ethoxycoumarin-O-deethylase (ECOD, esterase, glutathione-S-transferase (GST, and, and uridine 5'-diphosphoglucosyltransferase (UGT enzyme activity assays, or subjected to dose-response tests at four hour intervals throughout the day in both light/dark and constant light conditions. Peak expression of several XM genes cluster in late afternoon. Significant diurnal variation was observed in ECOD and UGT enzyme activity, however, no significant daily variation was observed in esterase or GST activity. Daily profiles of susceptibility to lethality after acute exposure to propoxur and fipronil showed significantly increased resistance in midday, while susceptibility to deltamethrin and malathion varied little. In constant light, which interferes with clock function, the daily variation in susceptibility to propoxur and in ECOD and UGT enzyme activity was depressed. CONCLUSIONS/SIGNIFICANCE: Expression and activities of specific XM enzymes fluctuate during the day, and for specific insecticides, the concentration resulting in 50% mortality varies significantly during the day. Time of day of chemical exposure should be an important consideration in experimental design, use of pesticides, and human risk assessment.

  9. Magnetic resonance (MR) imaging in delayed encephalopathy of acute carbon monoxide poisoning - comparison with CT -

    Eleven magnetic resonance (MR) and computed tomographic (CT) imaging were performed in nine patients with mild to moderate degree of delayed neuropsychiatric symptoms following acute carbon monoxide (CO) poisoning, to evaluate the capability of MR in demonstrating any additional finding to CT. The MR images were obtained using 0.15 Tesla resistive system with various combination of three pulse sequences, including partial saturation recovery, T2-weighted spin echo and inversion recovery. Bilateral white matter abnormalities suggesting demyelination were demonstrated in 4 patients with MR and in only 2 patients with CT. The contrast discrimination between normal and abnormal white matter proved to be better with T2-weighted spin echo and inversion recovery than with partial saturation recovery and CT. But necrosis of the globus pallidus (1 patient) and diffuse atrophy (3 patients) were equally demonstrated on both MR and CT. It is suggested that MR be used as a initial imaging method in the evaluation of the delayed encephalopathy following acute CO poisoning, especially for the detection of the possible white matter lesions. Acute carbon monoxide (CO) poisoning produces hypoxia by displacing oxygen from hemoglobin and preventing its release from hemoglobin in tissues, often resulting in fetal event. Victims who survive acute CO poisoning may have various delayed symptoms and signs. Occasionally, an apparent recovery is followed within two days to three weeks by a sudden neurological deterioration. The degree of neuropsychiatric symptoms depends upon the extent and severity of the pathologic changes in the brain. The pathologic effects of CO poisoning are present in almost all organs of patients. However, the most important changes occur in the brain, which consist of necrosis of the globus pallidus and reticular zone of the substantia nigra, and the degeneration of the cerebral white matter. The diagnostic superiority of magnetic resonance (MR) over CT has already

  10. Ulinastatin suppresses endoplasmic reticulum stress and apoptosis in the hippocampus of rats with acute paraquat poisoning

    Hai-feng Li

    2015-01-01

    Full Text Available Lung injury is the main manifestation of paraquat poisoning. Few studies have addressed brain damage after paraquat poisoning. Ulinastatin is a protease inhibitor that can effectively stabilize lysosomal membranes, prevent cell damage, and reduce the production of free radicals. This study assumed that ulinastatin would exert these effects on brain tissues that had been poisoned with paraquat. Rat models of paraquat poisoning were intraperitoneally injected with ulinastatin. Simultaneously, rats in the control group were administered normal saline. Hematoxylin-eosin staining showed that most hippocampal cells were contracted and nucleoli had disappeared in the paraquat group. Fewer cells in the hippocampus were concentrated and nucleoli had disappeared in the ulinastatin group. Western blot assay showed that expressions of GRP78 and cleaved-caspase-3 were significantly lower in the ulinastatin group than in the paraquat group. Immunohistochemical findings showed that CHOP immunoreactivity was significantly lower in the ulinastatin group than in the paraquat group. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining showed that the number of apoptotic cells was reduced in the paraquat and ulinastatin groups. These data confirmed that endoplasmic reticular stress can be induced by acute paraquat poisoning. Ulinastatin can effectively inhibit this stress as well as cell apoptosis, thereby exerting a neuroprotective effect.

  11. Using bosentan to treat paraquat poisoning-induced acute lung injury in rats.

    Zhongchen Zhang

    Full Text Available BACKGROUND: Paraquat poisoning is well known for causing multiple organ function failure (MODS and high mortality. Acute lung injury and advanced pulmonary fibrosis are the most serious complications. Bosentan is a dual endothelin receptor antagonist. It plays an important role in treating PF. There is no related literature on the use of bosentan therapy for paraquat poisoning. OBJECTIVE: To study the use of bosentan to treat acute lung injury and pulmonary fibrosis as induced by paraquat. METHOD: A total of 120 adult Wister male rats were randomly assigned to three groups: the paraquat poisoning group (rats were intragastrically administered with paraquat at 50 mg/kg body weight once at the beginning; the bosentan therapy group (rats were administered bosentan at 100 mg/kg body weight by intragastric administration half an hour after paraquat was administered, then the same dose was administered once a day; and a control group (rats were administered intragastric physiological saline. On the 3rd, 7th, 14th, and 21st days following paraquat exposure, rats were sacrificed, and samples of lung tissue and venous blood were collected. The levels of transforming growth factor-β1 (TGF-β1, endothelin-1 (ET-1, and hydroxyproline (HYP in the plasma and lung homogenate were determined. Optical and electronic microscopes were used to examine pathological changes. RESULT: The TGF-β1, ET-1, and HYP of the paraquat poisoning group were significantly higher than in the control group, and they were significantly lower in the 21st day therapy group than in the paraquat poisoning group on the same day. Under the optical and electronic microscopes, lung tissue damage was observed to be more severe but was then reduced after bosentan was administered. CONCLUSION: Bosentan can reduce inflammation factor release. It has a therapeutic effect on acute lung injury as induced by paraquat.

    2014-10-01

    Full Text Available Delayed encephalopathy after acute carbon monoxide poisoning (DEACMP is a syndrome constituted by acute dementia, psychiatric symptoms, pyramidal and extrapyramidal symptoms, which can be developed after the original clinical symptoms of carbon monoxide poisoning recovered. Lots of studies have been done to explain the mechanisms of DEACMP, and more and more researches have demonstrated that the immunological mechanism may be involved in or play an important role on the pathogenesis of the process. This article will review the researches of immunological mechanism of DEACMP in recent years and give some prompts to clinical study in the future. doi: 10.3969/j.issn.1672-6731.2014.10.006

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

    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.

  16. Sequential CT change of the globus pallidus in acute carbon monoxide poisoning

    We presented CT findings in the globus pallidus of three cases of acute CO poisoning. The initial low density lesions in the bilateral globus pallidus became isodense two to three weeks after the onset, and later appeared again as low density spots. These changes on CT were similar to the so-called ''fogging effect'' that is often found in cases of cerebral infarcts. (author)

    Organophosphorous (OP) pesticides are used frequently in agriculture, particularly in Asian countries over the past decades. Poisoning by these agents, either as acute or chronic in these nations, is a serious health problem. OP pesticides residue in fruits and vegetables that may not induce early clinical features, could also affect the human health. Therefore, medical and health professionals should be aware and learn more on the toxicology, prevention and proper management of OP poisoning....

  3. Acute Copper Sulfate Poisoning: Case Report and Review of Literature

    Mahesh Chand Meena

    2014-09-01

    Full Text Available Background: Copper sulfate ingestion is a relatively popular method for committing suicide in Indian subcontinent. It causes a high mortality rate, and so a growing concern has been raised to identify the severe alarming signs suggestive of poor prognosis and to improve treatment approaches. Case report: A 22-year-old unmarried man working as a painter was found unconscious at his friend residence. The patient developed hypotension, hemorrhagic gastroenteritis with hematemesis and melena, renal and hepatic failure, severe metabolic acidosis and intravascular hemolysis during admission at hospital. His signs were refractory to treatment with fluid replacement therapy, vasoactive drugs, antiemetic drugs, ranitidine, furosemide, methylene blue and 2,3 dimercaptopropane-1-sulphonate. He died six hours post-admission. In post-mortem examinations, there were multiple sub-pleural and sub-epicardial hemorrhages and the gastrointestinal mucosa was congested, hemorrhagic, and greenish blue in color. The liver, on histological examination, showed sub-massive hepatic necrosis. On toxicological analyses, copper sulfate was detected in preserved viscera and results for other heavy metals were negative. Conclusion: Hypotension, cyanosis, uremia and jaundice can be considered as signs of poor prognosis in copper sulfate poisoning. Copper sulfate ingestion is life-threatening due to its deleterious effects on the upper GI, kidneys, liver and blood. Having no time to waste, aggressive treatments should be immediately instituted and signs of poor prognosis should be kept in mind.

    E. C. Du Plessis

    2011-04-01

    Full Text Available Toxicity in cattle by the shrub Nolletia gariepina was induced experimentally by intraruminal administration of 3 g/kg dried, milled plant material as a single dose. The animals had to be starved for 24 hours before dosing, as dosing on a full rumen did not induce any signs of toxicity during 5 days of observation and clinical pathology monitoring. Clinical signs were not specific and varied according to the duration (acute versus subacute of the toxicological process. Clinical pathological parameters indicated renal and to a lesser extent hepatic damage, with raised serum concentrations of urea, creatinine, aspartate aminotransferase (AST and gamma glutamyl transferase (GGT. Increased urinary sodium and potassium concentration and GGT activity, as well as proteinuria, were evident. Histological and electron microscopic examinations revealed acute renal tubular epithelial cell degeneration and necrosis, especially of the proximal convoluted tubules. Mild hepatocellular degeneration was also noticeable.

  6. Acute methoxetamine and amphetamine poisoning with fatal outcome: A case report

    Marek Wiergowski

    2014-08-01

    Full Text Available Methoxetamine (MXE is a psychoactive substance distributed mostly via the Internet and is not liable to legal regulation in Poland. MXE has a toxicity profile similar to that of ketamine but longer-lasting effects. The paper describes a case of acute poisoning that resulted from recreational use of MXE and amphetamine and ended in death. In mid-July 2012, a 31-year old man was admitted to the clinical toxicology unit in Gdańsk because of poisoning with an unknown psychoactive substance. The patient was transported to the emergency department (ED at 5:15 a.m. in a very poor general condition, in a deep coma, with acute respiratory failure, hyperthermia (> 39°C and generalized seizures. Laboratory tests showed marked leukocytosis, signs of massive rhabdomyolysis, hepatic failure and beginning of acute renal failure. Despite intensive therapy, the patient died 4 weeks after the poisoning in the course of multi-organ dysfunction syndrome. Chemical and toxicological studies of serum and urine samples collected on the poisoning day at 1:40 p.m. confirmed that amphetamine and MXE had been taken earlier that day. Concentration of amphetamine in the serum (0.06 μg/ml was within the non-toxic range, while MXE (0.32 μg/ml was within the toxic range of concentrations. Amphetamine was also detected in the patient's hair, which suggested a possibility of its use within the last dozen weeks or so. The serious clinical course of intoxication and co-existence of amphetamine and MXE in the patient's blood and urine suggest the possibility of adverse interactions between them.

CONCLUSIONS: Despite clear reactivation of red cell acetylcholinesterase in diethyl organophosphorus pesticide poisoned patients, we found no evidence that this regimen improves survival or reduces need for intubation in patients with organophosphorus insecticide poisoning. The reason for this failure to benefit patients was not apparent. Further studies of different dose regimens or different oximes are required.

  9. Duration of an induced resistance of sheep to acute poisoning by Crotalaria retusa seeds

    Lisanka Angelo Maia

    2014-06-01

    Full Text Available The aim of this study was to determine the duration of the resistance after the end of the ingestion of non-toxic doses of Crotalaria retusa seeds. Ten sheep were divided into 3 groups of 3 animals each and a control group with 1 sheep. To induce resistance, sheep in groups 1, 2 and 3 received 20 daily doses of 2g kg-1 of C. retusa seeds, followed by 7 daily doses of 4g kg-1. To determine the duration of resistance the sheep in groups 1, 2 and 3 were challenged orally, 3, 7 and 15 days, respectively, after receiving the last dose of 4g kg-1, with a single dose of 5g kg-1. Sheep of groups 1 and 2 did not develop overt signs of poisoning. Two sheep of group 3, challenged 15 days after the end of the resistance induction period, showed signs of acute poisoning and died. These results suggest that the induced resistance of sheep to acute poisoning by C. retusa seeds is of short duration, from 7 to 15 days.

  10. Effects of acute organophosphate poisoning on pituitary target gland hormones at admission, discharge and three months after poisoning: A hospital based pilot study

    Pinaki Dutta

    2015-01-01

    Full Text Available Background: Organophosphate compound (OPC poisoning is common in the developing countries such as India. The acute and later effects of OPC poisoning on pituitary and target gland hormones is largely unknown. Materials and Methods: This prospective study was conducted at Postgraduate Institute of Medical Education and Research between January 2012 and March 2013. Fourteen patients (8 males, age 18-50 years with acute OPC poisoning were included in the study based on the history and clinical features, documented decreased in plasma cholinesterase activity or presence of the OPC in gastric lavage/blood samples. The hormonal parameters were done at baseline, at the time of discharge and at three months of follow-up. Results: A total of 14 patients out of 46 with the mean age of 30.1 ± 10.3 years were finally eligible for the study. Hormonal alterations at admission were similar to sick euhormonal syndrome. Overall 7 of them had nine hormonal deficits at three months of follow up, 4 having sub normal basal cortisol level and two each had low testosterone and growth hormone and only one had thyroxine deficiency. Conclusion: Acute organophosphate poisoning results in endocrine dysfunction akin to sick euhormonal syndrome. However, in a small subset of patients, varying level of hormonal insufficiency may occur either at admission or later. These observations need re-validation in a larger group of patients with specific OPC.

    1998-06-01

    Acute drug poisonings of the child is a major problem for health authorities all over the world, and are responsible for serious morbidity with mortality risks. The present retrospective study has involved 150 cases of drug poisoning observed in the Casablanca children's hospital over a period of 7 years. Most intoxication cases are accidental (84%), (mostly in children of 1 to 5 years old 74.6%), willful (11.3%), or iatrogenic (4.7%). Happening most often at home (95%) with a high frequency between 5 and 6 p.m. (24%) and 11 a 12 p.m. (13.3%), time of strong hunger. The large majority of drugs wer psychotropic agents (56%), principally diazepins (39%). Followed by oral contraceptive (8%), antihistaminics (8%), analgesics (7%), antibiotics (4%) and others (11%).

    2011-01-01

    Mushroom poisonings in Poland are quite common, especially in summer and autumn, but fly agaric (Amanita muscaria) and panther cap (Amanita pantherina) are rather rare cause of these intoxications. Fly agaric is a cause of deliberate poisoning, whereas panther cap poisoning also happens accidentally. The main toxins of these two mushrooms are ibotenic acid (pantherine, agarine), muscimol, muscazone and muscaridine. The other bioactive substances are stizolobic and stizolobinic acids and aminodicarboxyethylthiopropanoic acids. All these compounds are responsible for diverse picture of intoxication. An analysis of patients with Amanita muscaria and Amanita pantherina poisoning hospitalized in the Poznan Departament of Toxicology revealed that symptoms occurred after 30 minutes to 2 hours with vomiting, hallucinations, restlessness, increased psychomotor drive and central nervous system depression. Other antycholinergic symptoms like tachycardia and increased blood pressure, mydriasis, dry and red skin were seen only in a few cases. Acute respiratory failure was the most dangerous symptom observed in the course of poisoning. PMID:22010435

    To conduct a kinetic study of paraquat (PQ), we investigated 9 patients with acute PQ intoxication. All of them ingested more than 20 ml of undiluted PQ herbicide to commit suicide and arrived at our hospital early, not later than 7 h after PQ ingestion. The urine dithionite test for PQ in all of the nine patients was strongly positive at emergency room. Blood samples were obtained every 30 min for the first 2~3 h and then every 1 or 2 h, as long as the clinical progression was stable among the patients for 30 h after PQ ingestion. The area under the plasma concentration-time curve (AUCinf), which was extrapolated to infinity, was calculated using the trapezoidal rule. Toxicokinetic parameters, such as the terminal elimination half-life, apparent oral clearance, and apparent volume of distribution (Vd/F) were calculated. The maximum PQ concentration (Cmax) and the time to reach maximum PQ concentration (Tmax) were also obtained. Plasma PQ concentrations in nine patients were well described by a bi-exponential curve with a mean terminal elimination half-life of 13.1±6.8 h. Cmax and AUCinf were 20.8±25.7 mg/l and 172.5±160.3 h·mg/l, respectively. Apparent volume of distribution and apparent oral clearance were 50.9±61.3 l/kg and 173.4±111.2 l/h, respectively. There were a significant correlation (r =0.84; p<0.05) between the PQ amount ingested and Cmax. AUCinf also showed a significant correlation (r =0.83; p<0.05) with the PQ amount ingested. These correlations provide evidence that PQ has dose-linear toxicokinetic characteristics. PMID:26807021

    2015-01-01

    The honey bee is credited with approximately 85% of the pollinating activity necessary to supply about one-third of the world’s food supply. Well over 50 major crops depend on these insects for pollination. The crops produce more abundantly when honey bees are plentiful. Worker bees are the ones primarily affected by pesticides. Poisoning symptoms can vary depending on the developmental stage of the individual bee, and the kind of chemical employed. The oral toxicity of these insecticides: (p...

  16. Ultrastructural effects of acute tetraethyllead poisoning on nerve cells of the rabbit brain

    Niklowitz, W.J.

    1974-08-01

    A study of the ultrastructural alterations of nerve cell components in specific areas of the brain of the rabbit after acute poisoning with tetraethyllead (TEL). A single dose of 100 mg/kg of TEL caused neurological disorders such as convulsions after a latency of 12 to 18 h. An electron microscopic study revealed that the nerve cells of the areas investigated contained different stages of degenerative changes not demonstrated by light microscopy. These appear to be dependent on location and antedate the neurological disorders. The cytopathogenesis is discussed in the light of these findings and available biochemical data.

  18. Association of Pesticide Exposure with Neurologic Dysfunction and Disease

    Kamel, Freya; Hoppin, Jane A

    2004-01-01

    Poisoning by acute high-level exposure to certain pesticides has well-known neurotoxic effects, but whether chronic exposure to moderate levels of pesticides is also neurotoxic is more controversial. Most studies of moderate pesticide exposure have found increased prevalence of neurologic symptoms and changes in neurobehavioral performance, reflecting cognitive and psychomotor dysfunction. There is less evidence that moderate exposure is related to deficits in sensory or motor function or per...

    Pesticide formulation includes solvents (methanol and xylene) and antifreeze (ethylene glycol) whose metabolites are anions such as formic acid, hippuric acid, and oxalate. However, the effect of the anion gap on clinical outcome in acute pesticide intoxication requires clarification. In this prospective study, we compared the anion gap and other parameters between surviving versus deceased patients with acute pesticide intoxication. The following parameters were assessed in 1,058 patients with acute pesticide intoxication: blood chemistry (blood urea nitrogen, creatinine, glucose, lactic acid, liver enzymes, albumin, globulin, and urate), urinalysis (ketone bodies), arterial blood gas analysis, electrolytes (Na(+), K(+), Cl(-) HCO3 (-), Ca(++)), pesticide field of use, class, and ingestion amount, clinical outcome (death rate, length of hospital stay, length of intensive care unit stay, and seriousness of toxic symptoms), and the calculated anion gap. Among the 481 patients with a high anion gap, 52.2% had a blood pH in the physiologic range, 35.8% had metabolic acidosis, and 12.1% had acidemia. Age, anion gap, pesticide field of use, pesticide class, seriousness of symptoms (all P < 0.001), and time lag after ingestion (P = 0.048) were significant risk factors for death in univariate analyses. Among these, age, anion gap, and pesticide class were significant risk factors for death in a multiple logistic regression analysis (P < 0.001). In conclusions, high anion gap is a significant risk factor for death, regardless of the accompanying acid-base balance status in patients with acute pesticide intoxication. PMID:27366016

  20. Assessing the connection between organophosphate pesticide poisoning and mental health: A comparison of neuropsychological symptoms from clinical observations, animal models and epidemiological studies.

    Stallones, Lorann; Beseler, Cheryl L

    2016-01-01

    Psychiatry and psychology are beginning to recognize the importance of lead, mercury and heavy metals as causal partners in the development of mental disorders. Further, mental health researchers and clinicians are embracing the idea that the combined effects of genetics and environmental exposures can result in perturbations in brain neurochemistry leading to psychiatric disorders. The purpose of this review is to examine the biological foundations for the epidemiological observations previously identified by reviewing the toxicology literature and relating it to epidemiological studies addressing the role of poisoning with organophosphate pesticides (OPs) in neurobehavioral and neuropsychological disorders. The goal of this review is to raise awareness in the mental health community about the possibility that affective disorders might be the result of contributions from environmental and occupational pesticide poisoning.

  4. Brain temperature measured by 1H-magnetic resonance spectroscopy in acute and subacute carbon monoxide poisoning

    Brain temperature (BT) is associated with the balance between cerebral blood flow and metabolism according to the ''heat-removal'' theory. The present study investigated whether BT is abnormally altered in acute and subacute CO-poisoned patients by using 1H-magnetic resonance spectroscopy (MRS). Eight adult CO-poisoned patients underwent 3-T magnetic resonance imaging in the acute and subacute phases after CO exposure. MRS was performed on deep cerebral white matter in the centrum semiovale, and MRS-based BT was estimated by the chemical shift difference between water and the N-acetyl aspartate signal. We defined the mean BT + 1.96 standard deviations of the BT in 15 healthy controls as the cutoff value for abnormal BT increases (p < 0.05) in CO-poisoned patients. BT of CO-poisoned patients in both the acute and subacute phases was significantly higher than that of the healthy control group. However, BT in the subacute phase was significantly lower than in the acute phase. On the other hand, no significant difference in body temperature was observed between acute and subacute CO-poisoned patients. BT weakly correlated with body temperature, but this correlation was not statistically significant (rho = 0.304, p = 0.2909). The present results suggest that BT in CO-poisoned patients is abnormally high in the acute phase and remains abnormal in the subacute phase. BT alteration in these patients may be associated with brain perfusion and metabolism rather than other factors such as systemic inflammation and body temperature. (orig.)

    Ciguatoxins (CTXs) cause long-term disturbance of cerebral functions. The primary mechanism of neurotoxicity is related to their interaction with voltage-gated sodium channels. However, until now, the neurological targets for CTXs in the brain of intact animals have not been described. In our study, 1 day following oral exposure to 0.26 ng/g of Pacific ciguatoxin 1 (P-CTX-1), we performed in vivo electrophysiological recordings in the rat anterior cingulate cortex (ACC) and identified the increase in spontaneous firings and enhanced responses to visceral noxious stimulation. Local field recordings characterized the P-CTX-1-induced synaptic potentiation and blockage of the induction of electrical stimulation-induced long-term potentiation in the medial thalamus (MT)-ACC pathway. Furthermore, intracerebroventricular administration of P-CTX-1 at doses of 1.0, 5.0, and 10 nM produced a dose-dependent increase in ACC neuronal firings and MT-ACC synaptic transmission. Further studies showed upregulated Na(+) channel expression in astrocytes under pathological conditions. We hypothesized that the astrocytes might have been activated in the ciguatera poisoning in vivo. Increases in glial fibrillary acid protein expression were detected in reactive astrocytes in the rat ACC. The activation of astroglia was further indicated by activation of the gap junction protein connexin 43 and upregulation of excitatory amino acid transporter 2 expression suggesting that glutamate was normally rapidly cleared from the synaptic cleft during acute ciguatera poisoning. However, neurotoxicity and reactive astrogliosis were not detected in the ACC after 7 days of P-CTX-1 exposure. The present results are the first characterization of P-CTX-1-invoked brain cortex neuronal excitotoxicity in vivo and supported the theme that neuron and astroglia signals might play roles in acute ciguatera poisoning.

    Of the more than 5000 species of mushrooms known, 100 types are toxic and approximately 10% of these toxic types can cause fatal toxicity. A type of mushroom called Amanita phalloides is responsible for 95% of toxic mushroom poisonings. In this article, we report 2 cases of mushroom poisonings caused by Lactarius volemus, known as Tirmit by the local people. The patient and his wife were admitted to the emergency room with abdominal pain, nausea, and vomiting 20 hours after consuming Lactarius volemus, an edible type of mushroom. The patients reported that they had been collecting this mushroom from the mountains and eating them for several years but had never developed any clinicopathology to date. Further examination of the patients revealed a very rare case of acute pancreatitis due to mushroom intoxication. The male patient was admitted to the intensive care unit while his wife was followed in the internal medicine service, because of her relative mild clinical symptoms. Both patients recovered without sequelae and were discharged. In this article, we aimed to emphasize that gastrointestinal symptoms are often observed in mushroom intoxications and can be confused with acute pancreatitis, thus leading to misdiagnosis of patients. Early diagnosis and appropriate treatment can improve patients' prognosis and prevent the development of complications. PMID:26835473

    2016-01-01

    Objective. This study examined the hypothesis that correlations exist between the carbon monoxide exposure time and the carboxyhemoglobin concentration at the site of carbon monoxide poisoning, using a pulse carbon monoxide oximeter in rural areas or the carboxyhemoglobin concentration measured at a given medical institution. Background. In previous studies, no definitive relationships between the arterial blood carboxyhemoglobin level and the severity of carbon monoxide poisoning have been observed. Method. The subjects included patients treated for acute carbon monoxide poisoning in whom a medical emergency team was able to measure the carboxyhemoglobin level at the site of poisoning. We examined the relationship between the carboxyhemoglobin level at the site of poisoning and carbon monoxide exposure time and the relationships between the arterial blood carboxyhemoglobin level and carbon monoxide exposure time. Results. A total of 10 patients met the above criteria. The carboxyhemoglobin levels at the site of poisoning were significantly and positively correlated with the exposure time (rs = 0.710, p = 0.021), but the arterial blood carboxyhemoglobin levels were not correlated with the exposure time. Conclusion. In rural areas, the carboxyhemoglobin level measured at the site of carbon monoxide poisoning correlated with the exposure time. PMID:27239377

    Acute poisonings by medical, narcotic substances and alcohol are actual in Russia in the recent years. Comparison of analytic facilities of modern analytical techniques: chromatographic (HPLC, GC, GC-MS) and immuno-chemical (FPIA) in clinical toxicology for urgent diagnostics, assessment of the severity of acute poisoning and the efficacy of the treatment in patients with acute poisonings by psychotropic drugs, narcotics and alcohol have been done. The object of the study were serum, blood, urine of 611 patients with acute poisonings by amitriptyline, clozapine, carbamazepine, opiates and also alcohol. Threshold concentrations (threshold, critical and lethal) of the toxicants and their active metabolites which corresponded to different degrees of poisoning severity have been determined. The most comfortable and informative screening method for express diagnostics and assessment of severity of acute poisonings by psychotropic drugs and narcotics showed the HPLC with using automatic analyzers. FPIA using the automatic analyzer could be applied for screening studies, if group identification is enough. GC-FID method is advisable in case of poisoning by medical substances and narcotics in view of repeated investigation for assessment of the efficacy of the therapy. GC-MS could be advisable for confirming the results of other methods. GC-TCD possess high sensitivity and specificity and is optimal for express differential diagnostics and quantitative assessment of acute poisoning by ethanol and other alcohols. PMID:16225131

  12. Study on decorporating and detoxicating acute depleted uranium poison with some flavonoids

    In order to investigate decorporating and detoxicating acute depleted uranium poison of flavonoids, the decorporation effect of flavonoids with catechol group, chelating agent of catechols amino carboxylic acid type (8102) and dimethyl sulfoxide (DMSO) were studied under DU exposure and Wistar rats as animal model. In 3d later after injecting DU with dose of 20 mg/kg and then injecting flavonoids with dose of 10 mg/kg in abdomen, the mortality, uranium contents, kidney function and pathological observation of kidney were investigated. It has been found that nearly 20% mortality occurs both in the T2 and in T1 groups meanwhile 30% mortality occurs in the control group. But death has not been observed in 8102 group. The concentration of excreted urine uranium increases and the level of serum uranium decreases when T2 used. The retention of uranium in kidney with T2 group also increases. Large reducing of urea nitrogen and creatinine in serum has been observed in 8102 and F1 groups, and reducing of creatinine has also been observed in F2, T1 and T2 groups. The serious injury of kidney has not been observed in T2 group. The protection efficiency can be listed as T2> 8102>T1>F1>QU. It has been revealed that flavonoid T2 is the most effective protector from the damage and poison of DU. (authors)

  13. Paraquat poisoning: an experimental model of dose-dependent acute lung injury due to surfactant dysfunction

    M.F.R. Silva

    1998-03-01

    Full Text Available Since the most characteristic feature of paraquat poisoning is lung damage, a prospective controlled study was performed on excised rat lungs in order to estimate the intensity of lesion after different doses. Twenty-five male, 2-3-month-old non-SPF Wistar rats, divided into 5 groups, received paraquat dichloride in a single intraperitoneal injection (0, 1, 5, 25, or 50 mg/kg body weight 24 h before the experiment. Static pressure-volume (PV curves were performed in air- and saline-filled lungs; an estimator of surface tension and tissue works was computed by integrating the area of both curves and reported as work/ml of volume displacement. Paraquat induced a dose-dependent increase of inspiratory surface tension work that reached a significant two-fold order of magnitude for 25 and 50 mg/kg body weight (P<0.05, ANOVA, sparing lung tissue. This kind of lesion was probably due to functional abnormalities of the surfactant system, as was shown by the increase in the hysteresis of the paraquat groups at the highest doses. Hence, paraquat poisoning provides a suitable model of acute lung injury with alveolar instability that can be easily used in experimental protocols of mechanical ventilation

  14. Computed tomography of delayed encephalopathy of acute carbon monoxide poisoning - correlation with clinical findings -

    Cerebral computed tomography (CT) findings were described in twenty-six cases with the late sequelae of acute carbon monoxide poisoning and were computed with the neurological symptoms and signs. The CT findings include symmetrical periventricular white matter low density in five cases, globes pallidus low density in six cases, ventricular dilatation in seven cases, ventricular dilatation and sulci widening in three cases, and normal findings in ten cases. Only one case showed low densities in both periventricular white matter and globes pallidus. Late sequelae of the interval from of carbon monoxide poisoning were clinically categorized as cortical dysfunction, parkinsonian feature, and cerebella dysfunction. The severity of the clinical symptoms and signs of neurological sequelae is generally correlated with presence and multiplicity of abnormal brain CT findings. But of fourteen cases showing the parkinsonian feature, only five cases had low density of globes pallidus in brain CT. Another case showing small unilateral low density of globes pallidus had no parkinsonian feature but showed mild cortical dysfunction.

    Full Text Available Abstract Background Self-poisoning with pesticides is a major reason for high suicide rates in rural areas of many developing countries. Safer storage of pesticides may be one means of prevention. We have conducted a study to assess the acceptability and use of lockable boxes for storing pesticides in rural Sri Lanka. Methods Four hundred lockable metal storage boxes were given to farming households, 100 in each of four villages. Assessment interviews were conducted by Sumithrayo (NGO field workers immediately after boxes were supplied (T1, 11 – 14 weeks later (T2, 30 weeks later (T3, and 18 months later (T4. Data on suicide and self-harm were collected from local police and hospitals. Results At T1 only 1.8% (7/396 of households reported locking up pesticides, 72.5% (279/385 easy access to pesticides for adults and 50.4% (195/387 easy access for children. At T3 most informants in households using pesticides reported using the box all (82.3%, 298/362 or most of the time (7.2%, 26/362. Informants usually reported always locking the box (92.8%, 336/362 and most boxes were locked on inspection (93.6%, 339/362. By T4 there was some reduction in reporting that the box was kept locked all of the time (75.2%, 267/355 and the box being locked on inspection (73.8%, 262/355. Easy child access to the key was reported in relatively few households (10.7% at T4, although interviewers judged that this was possible in rather more (20.6%. Most informants regarded the box as useful (100% at T3 and 99.4% at T4, with convenience for storage, security, avoiding wastage, and protection of children being major factors. A message on the box about how to deal with bad feelings and the importance of safer storage was well received. The locks had been broken or the key lost in a few households. Conclusion Introduction of lockable boxes for storing pesticides to farming households in Sri Lanka appeared to be acceptable. Most households used the boxes responsibly

    Objective: To discuss the clinical and imaging characteristics of delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods: The clinical data of 14 patients with DEACMP were respectively analyzed. Results: Initial symptom included mentally falling (MMSE rate < 20 points) in 14 patients (100%), incontinence of urine in 11 patients (78%). Relatively significant increase of hematoma (HCT) (average level 0.503±0.027) was found in 6 patients. Three kinds of brain magnetic resonance imaging (MRI) appearance including diffuse white matter lesion, cortical lesion and basal nuclei lesion often existed in association. Therapy for improving circulation was given in 14 patients, and therapy with hormone was given in 9 patients; with 85% improvement rate. 5 patients without hormone therapy but with improving circulation therapy also received improvement. Conclusion: High level of HCT might be one of the causes of DECACMP due to acute disturbance of brain micro-circulation.. Close monitoring the change of HCT levels should be adopted for at least 3-6 months during therapy. Therapy for improving circulation and for anti-agglutination of platelets should be performed besides the routine high-tension oxygen therapy. Low FA value on DTI indicates the occurrence of a demyelization change in the brain long tract fibers, which indicated therapeutic effect of hormone treatment. And, therefore it would be better to perform DTI scan before therapy for individualized therapy. (authors)

    Full Text Available BACKGROUND: Intermediate syndrome (IMS is a major cause of death from respiratory failure following acute organophosphate poisoning. The objective of this study was to determine repetitive nerve stimulation (RNS predictors of IMS that would assist in patient management and clinical research. METHODS AND FINDINGS: Seventy-eight consenting symptomatic patients with organophosphate poisoning were assessed prospectively with daily physical examination and RNS. RNS was done on the right and left median and ulnar nerves at 1, 3, 10, 15, 20, and 30 Hz. The study was conducted as a prospective observational cohort study in the Central Province, Sri Lanka. IMS was diagnosed in ten out of 78 patients using a priori clinical diagnostic criteria, and five of them developed respiratory failure. All ten patients showed progressive RNS changes correlating with the severity of IMS. A decrement-increment was observed at intermediate and high frequencies preceding the onset of clinical signs of IMS. As the patient developed clinical signs of IMS, decrement-increment was progressively noted at low and intermediate frequencies and a combination of decrement-increment and repetitive fade or severe decrement was noted at high frequencies. Severe decrement preceded respiratory failure in four patients. Thirty patients developed forme fruste IMS with less severe weakness not progressing to respiratory failure whose RNS was characterized by decrement-increment or a combination of decrement-increment and repetitive fade but never severe decrements. CONCLUSIONS: Characteristic changes in RNS, preceding the development of IMS, help to identify a subgroup of patients at high risk of developing respiratory failure. The forme fruste IMS with the characteristic early changes on RNS indicates that IMS is a spectrum disorder. RNS changes are objective and precede the diagnosis and complications of IMS. Thus they may be useful in clinical management and research.

    Full Text Available Intermediate syndrome is a common complication found in patients with organo-phosphorus poisoning. The aim of this study was to find its incidence in this tribal dominated area of Chhattisgarh state. This is a retrospective study carried out at the ICU of a teaching Medical College hospital. In a period of one year, 720 cases of acute poisoning were admitted in the medical ICU ward, out of which, 682 cases (94.7% were of organo-phosphorus poisoning. 64 cases (9.3% had signs & symptoms of intermediate syndrome, which included inability to flex the neck, respiratory difficulty, convulsions and other features. All the 64 cases of intermediate syndrome required ventilatory support. Male: female ratio was 8:10. The commonest compound implicated in poisoning was Fenthion. Mortality was 18%. Patients with respiratory muscle weakness & proximal muscle paresis were the definitive predictors for the development of intermediate syndrome. Early recognition & prompt treatment has often proved successful, but, in mixed poisoning, recovery is variable and unpredictable.

    2015-10-01

    Results: Incidence was high among males (60.36% compared to females (39.64%. Most of the cases of acute poisoning were in the age group 10 to 30 years (60.95% followed by 30 to 50 years age group (30.77%. A majority of poisoning cases (27.2% were due to organophosphorus (OPC insecticide. Total mortality was found to be 5.32%. Mortality rate due to Paraquat, Abrus Pretorius seeds was significantly high compared with OPC because there is no specific antidote. Time lapse had a very significant role in the mortality in cases of poisoning. Conclusions: Poisoning is common with young males. The mortality is high, in cases of self-poisoning with parquet and abrus seeds. Despite the highest consumption rate, no mortality was observed with organophosphorus because of early medical intervention and specific antidote. Early medical care in a tertiary care hospital will help to reduce significant mortality in India. [Int J Res Med Sci 2015; 3(10.000: 2654-2657

  4. Determination of as by instrumental neutron activation analysis in sectional hair samples for forensic purposes. Chronic or acute poisoning?

    Complete text of publication follows. Autopsy of 29-year old woman suspicious of having committed suicide by ingestion of As2O3 yielded contradictory findings. All pathological findings as well as clinical symptoms suggested acute poisoning, while a highly elevated. As level of 26.4 μg g-1 in her hair collected at the autopsy (measured with ICP-MS) indicated chronic poisoning. To elucidate this discrepancy, INAA with proven accuracy of sectional hair samples obtained from a hair-brush from the left estate of the deceased person was performed. Levels of As found in this work in the range of 0.06-0.26 μg g-1 excluded chronic poisoning, because the person died after approximately 14 hours after the As2O3 ingestion. Two reasons for the discordant As results are considered: (1) accidental, non-removed contamination of hair on the As2O3 ingestion; (2) erroneous performance of ICP-MS. A brief review is also presented of As determination in hair for forensic purposes, including supposed, and until now frequently discussed, poisoning of Napoleon Bonaparte.

    Full Text Available Organophosphates (Ops. are the most widely used insecticides available today. These are a group of insecticides used in chemical sprays to kill bugs, and insects in orchards, vineyards, vegetables and cereal crops. The present study examined effects of the pesticide Methyl parathion, Dichlorvos and Chlorpyrifos on adult zebra fish were exposed to various concentrations (5, 10 & 25mg/L for 24 and 48hrs acute toxic study. Chlorpyrifos showed mortality in all concentrations and Methyl parathion and Dichlorvos showed the same in 25 mg/L. LC 50 value for Methyl parathion and Dichlorvos was 5 & 10 mg/L respectively. The total protein, LPO content was increased except SOD, Catalase in the brain tissue of the treated fishes.  There was no significant decrease in the GPX activity at 5ppm test groups. The GPX activity decreased significantly in test group treated with 10ppm and a significant difference was found between 5ppm and 10ppm test groups. The histopathological studies of brain tissue showed that neuronal degeneration and tissue damages in the brain of treated fishes when compared with the control. Ops. produce toxicity by inhibiting the cholinesterase enzymes in the nervous system. Monitoring of acetyl cholinesterase (AChE inhibition has been widely used in terrestrial and freshwater aquatic systems as an indicator of OP exposure and effects.

    Objective To investigate the incidence of pesticide poisoning with mixed preparation and risk factors contributing to it.Methods Twenty-five administrative villages were studied in three townships of Jiangsu and Shandong Provinces with cluster sampling.The sampled villages were divided into study group (12 villages) and control group (13 villages) with approximately equal number of people each.Pesticide sprayers in the study group applied mixed preparation containing organophosphorous and dimethrin and those in the control group applied single organophosphorous preparation.All the sprayers in sampled villages were interviewed with a same questionnaire about their situation of pesticide spraying during the observation period.Cases of pesticide poisoning were ascertained by seniors physicians in occupational diseases after group discussion.Results Incidence of pesticide poisoning was higher in 2 179 sprayers of the study group (10.10‰) than that in 2 615 of the control group (2.29‰), with a highly statistically difference (χ2=12.46,P<0.01) and an risk ratio (RR) of 4.45 (95% CI=1.94~10.05) adjusted for other risk factors by logistic regression.Other risk factors for pesticide poisoning with mixed preparation were smoking or taking food during spraying, leaking or breakdown of sprayers, without washing their whole body as soon as possible after spraying, poor personal protection, spraying for a long time, spraying by women and spraying pesticide on cotton.Conclusions If toxicity of mixed preparation of single pesticide showed a synergistic or additional effect, risk of poisoning by spraying mixed preparation increased.Health education and technical training should be strengthened for pesticide sprayers.%目的查明混配农药中毒的发病水平和农药中毒的危险因素。方法采用整群抽样方法,在江苏省和山东省的3个乡随机抽取25个行政村,按大约1∶1的人数比例分为研究组(12个行政村)与对照

  8. Acute oral and percutaneous toxicity of pesticides to mallards: Correlations with mammalian toxicity data

    Hudson, R.H.; Haegele, M.A.; Tucker, R.K.

    1979-01-01

    Acute oral (po) and 24-hr percutaneous (perc) LD50 values for 21 common pesticides (19 anticholinesterases, of which 18 were organophosphates, and one was a carbamate; one was an organochlorine central nervous system stimulant; and one was an organonitrogen pneumotoxicant) were determined in mallards (Anas platyrhynchos). Three of the pesticides tested were more toxic percutaneously than orally. An index to the percutaneous hazard of a pesticide, the dermal toxicity index (DTI = po LD50/perc LD50 ? 100), was also calculated for each pesticide. These toxicity values in mallards were compared with toxicity data for rats from the literature. Significant positive correlations were found between log po and log percutaneous LD50 values in mallards (r = 0.65, p 0.10). Variations in percutaneous methodologies are discussed with reference to interspecies variation in toxicity values. It is recommended that a mammalian DTI value approaching 30 be used as a guideline for the initiation of percutaneous toxicity studies in birds, when the po LD50 and/or projected percutaneous LD50 are less than expected field exposure levels.

    Full Text Available Abstract Objectives Changes in poisoning trends may affect both complications and outcomes in patients with acute poisoning. This study reports the treatments given and the frequency of complications, also related to treatment, mortality and sequelae related to various toxic agents. Methods All acute poisonings in adults (≥16 years admitted to the five hospitals in Oslo were included consecutively during one year (2008 to 2009 in an observational cross-sectional multicenter study. A standardized form was completed by the treating physician, which covered the study aims. Results There were 1065 admissions in 912 patients. The median length of hospital stay was one day, and 49% were observed in an intensive care unit (ICU. Active treatment was given to 83%, and consisted of supportive therapy (70%, antidote(s (38%, activated charcoal (16% and gastric lavage (9%. The most commonly used antidotes were flumazenil (19%, naloxone (17% and N-acetylcysteine (11%. The rate of treatment-related complications was 2.4% (21/884. Neither flumazenil, naloxone, nor the combination, was associated with convulsions or other complications. Among those receiving N-acetylcysteine, 5% (6/120 developed allergic reactions, one of which mandated discontinuation of treatment. Nineteen percent presented in a coma. Complications developed in 30%, compared with 18% in a 2003 study, mainly respiratory depression (12%, prolonged QTc interval (6% and hypotension (5%. Eight patients died (0.8% and five (0.5% survived with permanent sequelae, mainly anoxic brain damage. Discussion Few patients stayed more than two days. The use of the ICU was liberal, considering that only one out of five presented in a coma. Antidotes were frequently given diagnostically. Although N-acetylcysteine induced allergic reactions, most were mild and treatment discontinuation was only necessary once. The frequency of complications had almost doubled in five years, although the poisoning pattern was

    Three species of freshwater Brazilian fishes (pacu, Piaractus mesopotamicus; piavussu, Leporinus macrocephalus, and curimbatá, Prochilodus lineatus) were exposed to an acute dose of 5 ppm methyl parathion organophosphate pesticide. Three to five individuals per species were exposed, one at a time, to 40 liters tap water spiked with Folidol 600. Pesticide concentrations and cholinesterase (ChE) activities were evaluated in serum, liver, brain, heart, and muscle. The bioconcentration of methyl parathion was similar for all studied fishes. Brain tissue showed the highest pesticide concentration, reaching 80 ppm after exposure for 30 min to methyl parathion. Three to 5 hours of 5 ppm methyl parathion exposure provoked the death of all P. lineatus at 92% brain AChE inhibition, whereas fish from the other two species survived for up to 78 hours with less than 80% brain AChE inhibition. Our results indicate that acute toxic effects of methyl parathion to fish are correlated with brain AChE sensitivity to methyl paraoxon. PMID:26339593

METHODS: The study was done in patients admitted with history of poisoning under the department of medicine at RRMCH Hospital , Bengaluru from December 2013 to November 2014. This study includes 84 poisoning Patients who we re admitted to ICU care. Detailed history , clinical examination and laboratory inv est igations were done in all patients. Ventilator support and supportive treatment was instituted to required patients as p er our ICU criteria of intubation and Ventilation. Data was collected in structured format and analyzed. RESULTS: Majority of the cases were due to organophosphorus compound poisoning ( n=47 , 61% . Others had consumed drugs which included analgesics , carbomates , anti - hypertensive , spirit , benzodiazepines. A mongst these , 4 had consumed aluminum phosphide and all 4 of them died. In some history did not reveal the identity of the drugs. The most common indication for mechanical ventilation in these patients was respiratory failure due to OP poisoning. CONCLUSIO N: Pesticides were the main cause of poisoning ( 68.97% . The reasons being agriculture based economics , poverty due to poor agricultural yield and easy availability of pesticides. Patient education by conducting community based public awareness camps and l ectures might also help in bringing down the incidence of poisoning. The mortality could be decreased by enhanced ICU care , better medical management , appropriate supportive therapy and further restrictions on the highly toxic pesticides.

    Full Text Available O Brasil é um dos líderes mundiais em consumo de agrotóxicos e os trabalhadores expostos são numerosos e diversificados. As intoxicações agudas são a face mais visível do impacto destes produtos na saúde. A avaliação dos vários sistemas oficiais de informação que notificam os casos de intoxicações concluiu que nenhum deles responde adequadamente ao papel de sistema de vigilância. Na prática, só se registram os casos agudos e mais graves. Uma importante lacuna é a informação de exposição a agrotóxicos: a avaliação da única fonte oficial (os Receituários Agronômicos revelou muitas limitações. A revisão das publicações brasileiras aponta um crescimento quantitativo e qualitativo dos estudos nesta área, com vários tipos de abordagens. O impacto da intensa carga química e o enorme contingente de trabalhadores expostos são duas importantes razões para o desenvolvimento da pesquisa epidemiológica sobre intoxicações por agrotóxicos, que no Brasil ainda tem um vasto campo para se desenvolver.Brazil is one of the world leaders in pesticide consumption and exposed workers are numerous and diversified. Acute poisonings are just the most visible aspect of pesticide impact on human health. An assessment of many official information systems that notify pesticide poisoning concluded that none of them performed appropriately the role of a surveillance system. Only acute and severe cases are notified. One of the main gaps concerns exposure information: the only official source (the Agronomic Prescriptions has many limitations and is not available for research. A review of published articles in Brazil shows a quantitative and qualitative increase of studies in this area with many different approaches. The impact of such a high chemical burden and the huge numbers of workers exposed are two important reasons for the development of an epidemiological research on pesticide poisoning, an issue that has still a vast field to

In this study, we developed a validated QSAR model to predict acute oral toxicity of 329 pesticides to rats because a few QSAR models have been devoted to predict the Lethal Dose 50 (LD50) of pesticides on rats. This QSAR model is based on 17 molecular descriptors, and is robust, externally predictive and...

  15. Determination of As by instrumental neutron activation analysis in sectioned hair samples for forensic purposes: chronic or acute poisoning?

    Autopsy of 29-year old woman suspicious of committing suicide by the ingestion of As2O3 yielded contradictory findings. All pathological findings as well as clinical symptoms suggested acute poisoning, while a highly elevated As level of 26.4 μg g-1 in her hair collected at the autopsy, which was determined with inductively coupled plasma mass spectrometry indicated chronic poisoning. To elucidate this discrepancy, instrumental neutron activation analysis (INAA) with proven accuracy was performed of another set of sectioned hair samples. Levels of As found by INAA in the range of 0.16-0.26 μg g-1 excluded chronic poisoning, because the person died after approximately 14 h after the As2O3 ingestion. Two reasons for the discordant As results obtained by ICP-MS and INAA are considered: (1) accidental, non-removed contamination of hair on the As2O3 ingestion; (2) erroneous performance of ICP-MS.

  16. The Antidotal Effects of High-dosage γ-Aminobutyric Acid on Acute Tetramine Poisoning as Compared with Sodium Dimercaptopropane Sulfonate

    SUN Peng; HAN Jiyuan; WENG Yuying

    2007-01-01

    To investigate the therapeutic effect of high-dosage γ-aminobutyric acid (GABA) on acute tetramine (TET) poisoning, 50 Kunming mice were divided into 5 groups at random and the antidotal effects of GABA or sodium dimercaptopropane sulfonate (Na-DMPS) on poisoned mice in different groups were observed in order to compare the therapeutic effects of high-dosage GABA with those of Na-DMPS. Slices of brain tissue of the poisoned mice were made to examine pathological changes of cells. The survival analysis was employed. Our results showed that both high-dosage GABA and Na-DMPS could obviously prolong the survival time, delay onset of convulsion and muscular twitch, and ameliorate the symptoms after acute tetramine poisoning in the mice.Better effects could be achieved with earlier use of high dosage GABA or Na-DMPS. There was no significant difference in prolonging the survival time between high-dose GABA and Na-DMPS used immediately after poisioning. It is concluded that high-dosage GABA can effectively antagonize acute toxicity of teramine in mice. And it is suggested that high-dosage GABA may be used as an excellent antidote for acute TET poisoning in clinical practice. The indications and correct dosage for clinical use awaits to be further studied.

  17. Temperature-dependent acute toxicity of methomyl pesticide on larvae of 3 Asian amphibian species.

    2015-10-01

    Relative to other animal taxa, ecotoxicological studies on amphibians are scarce, even though amphibians are experiencing global declines and pollution has been identified as an important threat. Agricultural lands provide important habitats for many amphibians, but often these lands are contaminated with pesticides. The authors determined the acute toxicity, in terms of 96-h median lethal concentrations, of the carbamate pesticide methomyl on larvae of 3 Asian amphibian species, the Asian common toad (Duttaphrynus melanostictus), the brown tree frog (Polypedates megacephalus), and the marbled pygmy frog (Microhyla pulchra), at 5 different temperatures (15 °C, 20 °C, 25 °C, 30 °C, and 35 °C) to examine the relationships between temperature and toxicity. Significant interspecific variation in methomyl sensitivity and 2 distinct patterns of temperature-dependent toxicity were found. Because high proportions of malformation among the surviving tadpoles were observed, a further test was carried out on the tree frog to determine effect concentrations using malformation as the endpoint. Concentrations as low as 1.4% of the corresponding 96-h median lethal concentrations at 25 °C were sufficient to cause malformation in 50% of the test population. As the toxicity of pesticides may be significantly amplified at higher temperatures, temperature effects should not be overlooked in ecotoxicological studies and derivation of safety limits in environmental risk assessment and management.

    Jensen, Bodil Hamborg; Petersen, Annette; Christensen, Tue

    2009-01-01

    Organophosphorus and carbamate pesticides are acetylcholinesterase-inhibiting pesticides and as such have a common mode of action. We assessed the cumulative acute exposure of the population of Denmark to 25 organophosphorus and carbamate pesticide residues from the consumption of fruit, vegetables...... and cereals. The probabilistic approach was used in the assessments. Residue data obtained from the Danish monitoring programme carried out in the period 2004-2007, which included 6704 samples of fruit, vegetables and cereals, were used in the calculations. Food consumption data were obtained from...... the nationwide dietary survey conducted in 2000-2002. Contributions from 43 commodities were included in the calculations. We used the relative potency factor (RPF) approach to normalize the toxicity of the various organophosphorus and carbamate pesticides to the two index compounds chlorpyriphos...

  8. Hazardous pesticides in Central America.

    Wesseling, C; Aragón, A; Castillo, L; Corriols, M; Chaverri, F; de la Cruz, E; Keifer, M; Monge, P; Partanen, T J; Ruepert, C; van Wendel de Joode, B

    2001-01-01

    Pesticides are an extensively documented occupational and environmental hazard in Central America. Yet, severe problems persist. Toxic pesticide use in the Region increased during 1985-1999. High exposure levels and ineffectiveness of personal protective equipment evidence the difficulties for risk reduction. Acute poisonings remain a severe problem. Delayed and/or long-lasting health effects include dermatoses, cancer, and genotoxic, neurotoxic, and respiratory effects. The use of hazardous pesticides persists through deficiencies in government-driven assessment and risk management; excessive focus on regional harmonization; short-term economic interests; strong links between industry and governments; aggressive marketing; weak trade unions; and failure of universities to reach decision makers. Regulation based on local data is lacking. An agreement of the Ministries of Health for restricting the most toxic pesticides in Central America has potential for progress. The most effective way to reduce risk is to greatly reduce pesticide use. Actions needed include development of multidisciplinary strategies for local studies on health and environmental impact of pesticides; development of sustainable nonchemical agricultural technologies; evaluation of interventions; extending and sharing of expertise within the Region; strengthening of unions and communities; and redefining the role of industry toward development of safer products, with responsible marketing and reliable information.

    2015-01-01

    This study evaluated the relationships among copeptin, ischemia-modified albumin (IMA), and extent of myocardial injury in patients with acute carbon monoxide poisoning (ACOP). A total of 110 patients with different degrees of ACOP were selected as the poisoning group, and 30 healthy individuals as the control group. The levels of troponin I (cTnI), IMA, and copeptin were detected. Based on the presence of complications, the patients were assigned to the complication (26 patients) or non-complication (84 patients) group. Levels of cTnI, IMA, and copeptin were compared among the control, complication, and non-complication groups. Compared with the control group, in the 2 h after admission, the IMA levels decreased and copeptin levels increased in the poisoning group; these changes were more significant in patients with severe ACOP than in those with mild ACOP, and the difference was statistically significant (P < 0.05). There were no differences in the IMA and copeptin levels between the groups 7 days after admission; the cTnI levels increased more significantly in patients with severe ACOP than in patients with mild and moderate ACOP, and the differences were statistically significant (P < 0.05). In the complication group, at 7 days after admission, the IMA levels decreased whereas the copeptin and cTnI levels were significantly higher than in the non-complication group, with a statistically significant difference (P < 0.05). IMA was negatively correlated with copeptin. IMA and copeptin detection is clinically useful in the early diagnosis and prognosis of ACOP-related myocardial injury and in guiding early clinical drug application. PMID:26345979

    The agrarian population in low- and middle-income countries suffers from a number of adverse health effects due to pesticide exposure. In Zanzibar, the government subsidizes pesticides to enhance local rice production. The objectives of this study were to assess Zanzibar smallholder rice farmers' pesticide use and self-reported health symptoms in relation to pesticide exposure, training, and use of protective measures and to raise awareness for future local policy formulation. An exploratory cross-sectional interviewer-administered study was conducted among 99 rice farmers. Participants were selected based on convenience sampling and stratified by expected exposure category. The study participants reported using pesticides in World Health Organization (WHO) Class II. Of pesticide users, 61% reported one or more symptoms of possible acute pesticide poisoning. Only 50% of pesticide users had received training in safe handling and application of pesticides, but those who had displayed a higher use of protective measures. Farmers who did not use protective measures were more likely to have reported skin irritation and headache, which, together with eye irritation, were the most commonly reported acute symptoms. The main sociodemographic differences between the expected exposure categories of pesticide users and nonusers were in gender and education level. Scaling up of training in safe handling and application of pesticides is needed. Further studies are required to better understand the mechanisms behind the choice to use pesticides or not.

    Objective To analyze the incidence and risk factors of unplanned extubation(UE) in organophosphorus pesticide poisoning patients with endotracheal intubation. Methods The prevalence and risk factors of UE in 43 organophosphorus pesticide poisoning patients with endotracheal intubation were retrospectively analyzed. Results The incidence of UE in organophosphorus pesticide poisoning patients with endotracheal intubation was 30.23 percent. Logistic regression analysis showed that Ramsay sedation score (OR=0.079) and sputum scab score (OR =7.029) were the risk factors of UE. Conclusions The incidence of UE in organophosphorus pesticide poisoning patients is relatively high. Ramsay sedation score and sputum scab score are the independent risk factors of UE. Effective sedation measures and airway management may reduce the incidence of UE and increase the successful rescue rate of organophosphorus pesticide poisoning patients.%目的 总结有机磷农药中毒气管插管患者非计划性拔管(Unplanned extubation,UE)的发生率,分析UE发生的相关原因.方法 回顾性分析2009年1月至2010年12月我科收治的43例有机磷农药中毒气管插管患者年龄、性别、Ramsay评分、阿托品日平均用量、气道痰痴评分、使用气管导管型号等临床资料,评估UE发生率并筛查UE的临床危险因素.结果 本组有机磷农药中毒气管插患者UE发生率为30.23%,单因素分析显示,UE组与非UE组Ramsay评分、阿托品日平均用量及气道痰痴评分差异有统计学意义,Logistics逐步回归分析显示Ramsay评分(OR=0.079)和气道痰痴评分(OR=7.029)与UE的发生独立相关.结论 有机磷农药中毒气管插患者UE发生率较高,Ramsay评分低和气道痰痂评分高是发生UE的独立危险因素.有效镇静和强化气道管理可能有助于减少UE的发生,提高有机磷农药中毒患者的救治成功率.

  18. Effect of a brief outreach educational intervention on the translation of acute poisoning treatment guidelines to practice in rural Sri Lankan hospitals: a cluster randomized controlled trial.

    Lalith Senarathna

    Full Text Available BACKGROUND: In developing countries, including Sri Lanka, a high proportion of acute poisoning and other medical emergencies are initially treated in rural peripheral hospitals. Patients are then usually transferred to referral hospitals for further treatment. Guidelines are often used to promote better patient care in these emergencies. We conducted a cluster randomized controlled trial (ISRCTN73983810 which aimed to assess the effect of a brief educational outreach ('academic detailing' intervention to promote the utilization of treatment guidelines for acute poisoning. METHODS AND FINDINGS: This cluster RCT was conducted in the North Central Province of Sri Lanka. All peripheral hospitals in the province were randomized to either intervention or control. All hospitals received a copy of the guidelines. The intervention hospitals received a brief out-reach academic detailing workshop which explained poisoning treatment guidelines and guideline promotional items designed to be used in daily care. Data were collected on all patients admitted due to poisoning for 12 months post-intervention in all study hospitals. Information collected included type of poison exposure, initial investigations, treatments and hospital outcome. Patients transferred from peripheral hospitals to referral hospitals had their clinical outcomes recorded. There were 23 intervention and 23 control hospitals. There were no significant differences in the patient characteristics, such as age, gender and the poisons ingested. The intervention hospitals showed a significant improvement in administration of activated charcoal [OR 2.95 (95% CI 1.28-6.80]. There was no difference between hospitals in use of other decontamination methods. CONCLUSION: This study shows that an educational intervention consisting of brief out-reach academic detailing was effective in changing treatment behavior in rural Sri Lankan hospitals. The intervention was only effective for treatments with

  19. Chronic Arsenic Poisoning Probably Caused by Arsenic-Based Pesticides: Findings from an Investigation Study of a Household

    2016-01-01

    Full Text Available In addition to naturally occurring arsenic, man-made arsenic-based compounds are other sources of arsenic exposure. In 2013, our group identified 12 suspected arsenicosis patients in a household (32 living members. Of them, eight members were diagnosed with skin cancer. Interestingly, all of these patients had lived in the household prior to 1989. An investigation revealed that approximately 2 tons of arsenic-based pesticides had been previously placed near a well that had supplied drinking water to the family from 1973 to 1989. The current arsenic level in the well water was 620 μg/L. No other high arsenic wells were found near the family’s residence. Based on these findings, it is possible to infer that the skin lesions exhibited by these family members were caused by long-term exposure to well water contaminated with arsenic-based pesticides. Additionally, biochemical analysis showed that the individuals exposed to arsenic had higher levels of aspartate aminotransferase and γ-glutamyl transpeptidase than those who were not exposed. These findings might indicate the presence of liver dysfunction in the arsenic-exposed individuals. This report elucidates the effects of arsenical compounds on the occurrence of high levels of arsenic in the environment and emphasizes the severe human health impact of arsenic exposure.

    2011-01-01

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

  1. Contributing Factors for Acute Illness/Injury from Childhood Pesticide Exposure in North Carolina, USA, 2007–2013

    Nirmalla Barros

    2016-02-01

    Full Text Available Between 2007 and 2013, there were 685 events with evidence of a relationship between pesticide exposure and acute illness/injury among persons less than 18 years old in North Carolina (United States. Median age of children affected was 4.3 years (range: 0.2–17.9. Distribution by gender was similar across all age groups. One fatality and four high severity events were observed. The greatest proportion (42% of events had ocular exposures, followed by dermal (25% and inhalation (18% exposures. When more than one route of exposure occurred, dermal and ocular routes were the most common (46%. Almost all events took place indoors and 32 events involved contact with pets. Insecticides (53% and insect repellants (31% were the most frequent agents contributing to these events. Manual application of pesticides contributed to the greatest number of events (25%, while application through a pressurized can and use of a trigger pump were involved in 21% and 15% of events, respectively. Additional contributors were due to inappropriate storage of pesticides and improper use of the pesticide. These contributing factors can be removed or minimized if pesticides are stored outside the residence or out of the reach of children and pets, and adequate ventilation is ensured whenever pesticides are applied.

Of these, 90% of fatal poisoning occurs in developing countries mainly among agricultural workers. It is estimated that more than 50,000 people die every year from toxic exposure in India. OBJECTIVES 1. To study the current trend of poisoning in a District of West Bengal. 2. To know the burden of pesticide poisoning in society. MATERIAL AND METHODS A hospital based retrospective cross sectional study was conducted in a district hospital of West Bengal. Ethical clearance was taken from Ethics Committee. All the registered cases of poisoning in a district hospital during the study period were included in the study. Data was collected from medico-legal register and respective case sheets using pre-structured and validated questionnaire containing demographic and medico-legal aspects of poisoning for the period of 2 years (March 2014-March 2016. Data was analysed using the SPSS version 16 software. Descriptive statistics were reported as mean (SD for continuous variables and frequency (percentage for categorical variables. RESULT Total 7280 patients reported to casualty department over two years; 5.21% were reported to be the poisoning cases. Out of total 380 poisoning cases, 84 (22.10% patients died. Maximum poisoning cases were from rural area falling mainly in the age group of 21-30 and above 50 years. Organ phosphorus poisoning was noted in 46.42% of reported cases. CONCLUSIONS Based on the study findings, we could understand the trend of poisoning in the study area. It is very important to identify these changing trends in the study area, as it will be helpful for policy makers to equip health care institutions which can lead to better management of cases and reduction in the mortality related to poisoning

    Full Text Available Context: India is a developing country in south Asia. Rural population of this country is mostly dependant on agriculture. Pesticides, mainly the organophosphorus compounds are the most frequently used substances in agriculture and thus are easily accessible. Animal bites such as snake bite, scorpion bites are also common, as people here are mainly involved in the field work. Aims: This includes, knowing the pattern of poisoning in India along with various parameters, such as mode of poisoning, type of poison, outcome of the poisoning, the most vulnerable age group involved in poisoning, so that the study will help in rapid clinical diagnosis and immediate treatment of the cases leading to decreased mortality and morbidity. Setting and design: Retrospective observational study. Materials and Methods: The study was conducted at Govt. Hospital, Yavatmal. Poisoning cases reported to casualty and post-mortem cases of poisoning brought to the hospital from 01/06/2003 to 30/05/2004 were included in the study. Result: Total 1003 patients studied; acute poisoning in the age group of 21-30 years was the most common with higher frequency in males. Most common mode was suicidal. Most common agent responsible for poisoning was organophosphorus compounds followed by snake bite. Overall mortality due to poisoning was 12%. It was highest in insecticidal poisoning. Conclusion: It was seen that adults between 21 and 30 years of age were more prone to suicidal poisoning with organophosphorous compounds followed by accidental poisoning due to snake bite. Steps are needed to be taken to educate the people, to improve their socioeconomic status and also to provide better treatment facilities at grass root level.

    Quantitative Structure Activity Relationship (QSAR) models are expected to play an important role in the risk assessment of chemicals on humans and the environment. In this study, we developed a validated QSAR model to predict acute oral toxicity of 329 pesticides to rats because a few QSAR models have been devoted to predict the Lethal Dose 50 (LD50) of pesticides on rats. This QSAR model is based on 17 molecular descriptors, and is robust, externally predictive and characterized by a good applicability domain. The best results were obtained with a 17/9/1 Artificial Neural Network model trained with the Quasi Newton back propagation (BFGS) algorithm. The prediction accuracy for the external validation set was estimated by the Q(2)ext and the root mean square error (RMS) which are equal to 0.948 and 0.201, respectively. 98.6% of external validation set is correctly predicted and the present model proved to be superior to models previously published. Accordingly, the model developed in this study provides excellent predictions and can be used to predict the acute oral toxicity of pesticides, particularly for those that have not been tested as well as new pesticides.

    Abstract Background: Highly hazardous organophosphorus (OP) insecticides are responsible for most pesticide poisoning deaths. As they are removed from agricultural practice, they are often replaced by carbamate insecticides of perceived lower toxicity. However, relatively little is known about poisoning with these insecticides. Methods: We prospectively studied 1288 patients self-poisoned with carbamate insecticides admitted to six Sri Lankan hospitals. Clinical outcomes were recorded for each patient and plasma carbamate concentration measured in a sample to confirm the carbamate ingested. Findings: Patients had ingested 3% carbofuran powder (719), carbosulfan EC25 liquid (25% w/v, 389), or fenobucarb EC50 liquid (50% w/v, 127) formulations, carbamate insecticides of WHO Toxicity Classes Ib, II, and II, respectively. Intubation and ventilation was required for 183 (14.2%) patients while 71 (5.5%) died. Compared with carbofuran, poisoning with carbosulfan or fenobucarb was associated with significantly higher risk of death [carbofuran 2.2%; carbosulfan 11.1%, OR 5.5 (95% CI 3.0–9.8); fenobucarb 6.3%, OR 3.0 (1.2–7.1)] and intubation [carbofuran 6.1%; carbosulfan 27.0%, OR 5.7 (3.9–8.3); fenobucarb 18.9%, OR 3.6 (2.1–6.1)]. The clinical presentation and cause of death did not differ markedly between carbamates. Median time to death was similar: carbofuran 42.3 h (IQR 5.5–67.3), carbosulfan 21.3 h (11.5–71.3), and fenobucarb 25.3 h (17.3–72.1) (p = 0.99); no patients showed delayed onset of toxicity akin to the intermediate syndrome seen after OP insecticide poisoning. For survivors, median duration of intubation was 67.8 h (IQR 27.5–118.8) with no difference in duration between carbamates. Reduced GCS at presentation was associated with worse outcome although some patients with carbosulfan died after presentation with normal GCS. Conclusions: We did not find carbamate insecticide self-poisoning to vary markedly according to the carbamate

    Background. Acute carbon monoxide poisoning (ACOP) is a significant cause of morbidity and mortality in many countries. Twelve Hand Jing Points (THJP) have been believed to be effective to treat all kinds of emergency calls in traditional Chinese medicine (TCM) for more than 3000 years. This randomized controlled trial (RCT) is designed to evaluate the effectiveness of THJP in curing acute carbon monoxide poisoning in first aid treatment. This paper reports the protocol of the trial. Methods/Design. This RCT is a multicenter, randomized, controlled study undergoing in China. The compliant patients are divided into the bloodletting group and standard of care group. With first aid treatments given to both of the groups, the bloodletting group is bleeding at THJP upon being hospitalized. Primary outcomes and secondary outcomes will be measured and compared between these two groups. Before treatment, immediately after treatment, and 30 minutes, 1 hour, and 4 hours after treatment, patients' basic vital signs and state of consciousness were observed. Before treatment and 1 and 4 hours after treatment, carboxyhemoglobin concentration in venous blood samples was detected. Discussion. The objective of this study is to provide convincing evidence to clarify the efficacy and safety of THJP for early treatment of acute carbon monoxide poisoning. PMID:26339271

    Weaver, Lindell K; Deru, Kayla

    2016-01-01

    Carbon monoxide (CO) poisoning is common, but it has rarely been reported to cause ischemic colitis. In this case, a 34-year-old female with depression presented to an emergency department after a period of unconsciousness, with urinary and bowel incontinence, following exposure to car exhaust. Her carboxyhemoglobin level was 23%. She had metabolic acidosis. She was transferred to our facility for hyperbaric oxygen treatment, where she had intractable nausea/vomiting with abdominal pain and bright-red bleeding per rectum. She exhibited lower abdominal tenderness and hypoactive bowel sounds. Vital signs were: temperature 36.8 degrees C; blood pressure 137/ 86 mmHg; heart rate 114 beats/minute; respiratory rate 28 breaths/minute. The patient's electrocardiogram showed sinus tachycardia with T-wave inversions in leads I, aVL and V3-V6. The troponin I level peaked at 3.7 ng/ml. Echocardiogram showed a reduced ejection fraction of 30%-35%, with akinesis in the posterior lateral and distal anterior distributions. Computed tomography of the abdomen revealed diffuse colonic mural thickening, supporting mesenteric ischemia. Sigmoidoscopy showed edematous friable pale mucosa from rectum to distal sigmoid colon. Hyperbaric oxygen was deferred based on the patient's status. Over three days, the initial hematochezia progressed to melena and then resolved. Adenosine cardiac stress MRI was normal. She was transferred to the psychiatry service and discharged four days later. Four years later, she has no gastrointestinal, cardiac or cognitive problems. PMID:27265995

    Full Text Available This article reports cases of nitrate poisoning in Indian indigenous cattle breeds comprising two Gir cows aging 4 years each, and one Barugur cow at 1.5 years of age. The cattle with case history of sudden death and oozing of partially clotted blood from the anal opening were brought to the Central University Laboratory (CUL, Center for Animal Health Studies (CAHS, Tamil Nadu Veterinary and Animal Sciences University (TANUVAS for diagnostic investigation with a suspicion of anthrax. According to anamnesis, all the animals were clinically normal and did not reveal any abnormality on the previous day. The animals were fed with recently harvested sorghum leaves and stalks. Smears examined for anthrax were found negative. Biological test (mice inoculation for anthrax was also negative. Gross lesions on necropsy examination of the carcases were suggestive of nitrate intoxication. Finally, nitrate intoxication of these cattle was confirmed by chemical and toxicological analysis of fodder, rumen content, aqueous humor, liver, kidney and urine.

    Marashi, Sayed Mahdi; Nasri Nasrabadi, Zeynab; Jafarzadeh, Mostafa; Mohammadi, Sogand

    2016-07-01

    A 40-year-old male patient with suicidal ingestion of one tablet of aluminium phosphide was referred to the department of toxicology emergency of Baharloo Hospital, Tehran, Iran. The garlic odor was smelled from the patient and abdominal pain and continuous vomiting as well as agitation and heartburn were the first signs and symptoms. Systolic and diastolic blood pressures at the arrival time were 95 and 67 mmHg, respectively. Gastric lavage with potassium permanganate (1:10,000), and 2 vials of sodium bicarbonate through a nasogastric tube was started for the patient and the management was continued with free intravenous infusion of 1 liter of NaCl 0.9% serum plus NaHCO3, hydrocortisone acetate (200 mg), calcium gluconate (1 g) and magnesium sulfate (1 g). Regarding the large intravenous fluid therapy and vasoconstrictor administering (norepinephrine started by 5 µg/min and continued till 15 µg/min), there were no signs of response and the systolic blood pressure was 49 mmHg. At this time, hydroxyethyl starch (HES) (6% hetastarch 600/0.75 in 0.9% sodium chloride) with a dose of 600 cc in 6 hours was started for the patient. At the end of therapy with HES, the patient was stable with systolic and diastolic blood pressure of 110 and 77 mmHg, respectively. He was discharged on the 6th day after the psychological consultation, with normal clinical and paraclinical examinations. This is the first report of using HES in the management of AlP poisoning and its benefit to survive the patient. PMID:27424021

    2011-01-01

    Full Text Available Background: Poisoning with various substances is a global problem. It is one of the most important reasons for emergency admission in the hospital. The earlier the initial resuscitations, gastric decontamination and use of specific antidotes, the better is the outcome. Epidemiology of poisoning differs from region to region. This study was carried out to determine the pattern and severity of poisoning in a tertiary care hospital. Objective: To characterize the poisoning cases admitted in Enam Medical College Hospital. Materials and Methods: All cases admitted to the emergency department of Enam Medical College Hospital during the period of April to December, 2010 were evaluated retrospectively. We reviewed data obtained from the hospital medical records and included the following factors: demographic characteristics, etiology and outcome of the acutely poisoned patients. Total 84 poisoning cases were found and they were included in the study. Results: The overall case fatality rate was 3.5%. More detailed data from 2010 reveals that two-thirds of the patients were 20-30 years old, 53% male and 47% female. Organophosphorus was the most common cause (73.9% followed by unknown poisoning (9.5%, sedative (5.9%, harpic (4.7%, aluminium phosphide (2.4%, savlon (1.2%, paracetamol (1.2% and amitryptiline (1.2%. 90.5% cases were suicidal and 9.5% were homicidal. Conclusion: This study provides important information on the characteristics of the poisoning in this region. Community education about the danger of the drugs and reduction of exposure to pesticides are recommended.

  15. DNA pooling base genome-wide association study identifies variants at NRXN3 associated with delayed encephalopathy after acute carbon monoxide poisoning.

    Wenqiang Li

    Full Text Available Delayed encephalopathy after acute carbon monoxide poisoning (DEACMP is more characteristic of anoxic encephalopathy than of other types of anoxia. Those who have the same poisoning degree and are of similar age and gender have a greater risk of getting DEACMP. This has made it clear that there are obvious personal differences. Genetic factors may play a very important role. The authors performed a genome-wide association study involving pooling of DNA obtained from 175 patients and 244 matched acute carbon monoxide poisoning without delayed encephalopathy controls. The Illumina HumanHap 660 Chip array was used for DNA pools. Allele frequencies of all SNPs were compared between delayed encephalopathy after acute carbon monoxide poisoning and control groups and ranked. A total of 123 SNPs gave an OR >1.4. Of these, 46 mapped in or close to known genes. Forty-eight SNPs located in 19 genes were associated with DEACMP after correction for 5% FDR in the genome-wide association of pooled DNA. Two SNPs (rs11845632 and rs2196447 locate in the Neurexin 3 gene were selected for individual genotyping in all samples and another cohort consisted of 234 and 271 controls. There were significant differences in the genotype and allele frequencies of rs11845632 and rs2196447 between the DEACMP group and controls group (all P-values <0.05. This study describes a positive association between Neurexin 3 and controls in the Han Chinese population, and provides genetic evidence to support the susceptibility of DEACMP, which may be the resulting interaction of environmental and genetic factors.

  16. THE ROLE OF EARLY HAEMOPERFUSION/HAEMODIALYSIS WITH STEROIDS, CYCLOPHOSPHAMIDE, N ACETYL CYSTEINE AND EVEROLIMUS IN ACUTE PARAQUAT POISONING: IS THERE STILL HOPE?

    Rajesh

    2016-01-01

    Full Text Available BACKGROUND Acute Paraquat poisoning is associated with very high mortality rate. There are no standardized treatment protocols and no effective antidote. AIMS In the absence of an effective antidote, early removal of paraquat by haemoperfusion/haemodialysis and addition of immunosuppressive agents, anti-oxidants and anti-fibrotic agents to counter the effect of paraquat may be beneficial. We present our experience of using Haemoperfusion/Haemodialysis in combination with pulse steroids, intravenous cyclophosphamide N Acetylcysteine infusion and Everolimus in such patients. MAIN METHODS AND RESULTS This study is conducted in two phases, during the first phase, the patients with paraquat poisoning are treated by the physicians as done in usual practice. In the second phase, standardized protocols were followed and patients received either early Haemoperfusion or Haemodialysis along with steroids, cyclophosphamide, N acetyl cysteine and Everolimus. We noted that with the use of standardized treatment protocol, the survival rate of severe paraquat poisoning has increased from 8% to 45.8%. CONCLUSION Early Haemoperfusion/haemodialysis when used in combination with steroids, Cyclophosphamide, N acetyl infusion and Everolimus may be an effective treatment strategy in patients with severe paraquat poisoning.

The magnitude of overdose ranged from 1.5 to 43 (median 8 times the usual dose in adults. Twelve cases (30% had attributable symptoms. The majority of these were minor and included gastrointestinal complaints and liver function test and blood count abnormalities. Symptoms were experienced by patients who took at least 1.5-times their usual daily thiopurine dose. Overdoses over two or more consecutive days, even if of modest size, were less well tolerated. One case of azathioprine and allopurinol co-ingestion over consecutive days led to agranulocytosis. Decontamination measures were undertaken in 11 cases (10 activated charcoal, 1 gastric lavage and these developed fewer symptoms than untreated patients. This study shows that acute overdoses with thiopurines have a favourable outcome in the majority of cases and provides preliminary evidence that gastrointestinal decontamination with activated charcoal may reduce symptom development after overdose of these substances if patients present to medical services soon after ingestion.

    Literature regarding acute human toxicity of thiopurines is limited to a handful of case reports. Our objectives were to describe all cases of overdose with thiopurines reported to the Swiss Toxicological Information Centre between 1995-2013. A retrospective analysis was performed to determine circumstances, magnitude, management and outcome of overdose with these substances. A total of 40 cases (14 paediatric) were reported (azathioprine, n = 35; 6-mercaptopurine, n = 5). Of these, 25 were with suicidal intent, 12 were accidental and 3 were iatrogenic errors. The magnitude of overdose ranged from 1.5 to 43 (median 8) times the usual dose in adults. Twelve cases (30%) had attributable symptoms. The majority of these were minor and included gastrointestinal complaints and liver function test and blood count abnormalities. Symptoms were experienced by patients who took at least 1.5-times their usual daily thiopurine dose. Overdoses over two or more consecutive days, even if of modest size, were less well tolerated.

    The accidental intoxications constitute more and more a serious problem among young children in the developing countries because of their frequency and difficulties for taking care of those victims. The objective of our work was to study acute intoxications among children in order to determine the frequency, to identify the products in question and to determine the impact of those accidents in the future life of the victims. The study was carried out in the Paediatric Service of the CHU Gabriel Touré from January 2001 to June 2002. We enrolled 89 children from 0 to 15 years of age. Information on our patients was recorded on investigational questionnaire and completed with data from their entry and hospitalization records. Among 8237 children hospitalized during the study period, 89 of them had acute intoxication i.e. 1.08%. Children less than five years of age were more frequent with 85.4% with a male prevalence of 61.8%. Antimalarial drugs and petroleum were the most accused products. Administration of milk and provoked vomiting were the attitudes and practices of the entourage of the victims when intoxication occurs. The evolution was favourable in 67.2% of the cases with a hospital lethality of 13.7%. PMID:19617084

  20. Health Aspects of Organophosphorous Pesticides in Asian Countries

    B Balali-Mood

    2012-10-01

    Full Text Available Organophosphorous (OP pesticides are used frequently in agriculture, particularly in Asian countries over the pastdecades. Poisoning by these agents, either as acute or chronic in these nations, is a serious health problem. OP pesticidesresidue in fruits and vegetables that may not induce early clinical features, could also affect the human health.Therefore, medical and health professionals should be aware and learn more on the toxicology, prevention and proper management of OP poisoning. The well-known mechanism of OP toxicity is the inhibition of acetyl cholinesterase,resulting in an accumulation of acetylcholine and continued stimulation of acetylcholine receptors. Therefore, they arealso called anticholinesterase agents. Determination of blood acetyl cholinesterase and butyryl cholinesterase activities remains a mainstay for the rapid initial screening of OP pesticides. Quantitative analysis of OP and their degradation products in plasma and urine by mass spectrometric methods is a more specific method, but is expensive and limited to specialized laboratories. Therefore, history of OP pesticides exposure and clinical manifestations of a cholinergic syndrome is sufficient for management of the exposed patients. However, electrophysiological tests may be requiredfor the diagnosis of delayed neuropathy of OP poisoning. The standard management of OP poisoning includes decontamination,atropine sulphate with an oxime. Recent advances focus on blood alkalinisation and magnesium sulphate as promising adjunctive therapies. Preventive measures in OP exposure are of great importance in human health in developing countries. Therefore, regulations and controls on safe use of OP particularly in Asian countries are recommended.

  2. Pesticide knowledge, practice and attitude and how it affects the health of small-scale farmers in Uganda

    Oesterlund, Anna H; Thomsen, Jane F; Sekimpi, Deogratias K;

    2014-01-01

    BACKGROUND: Over the past years there has been an increase in the use of pesticides in developing countries. This study describes pesticide use among small-scale farmers in Uganda and analyses predictors of pesticide poisoning (intoxication) symptoms. METHOD: A cross-sectional study was conducted...... using a standardized questionnaire. Some 317 small-scale farmers in two districts in Uganda were interviewed about pesticide use, knowledge and attitude, symptoms of intoxication, personal protective equipment (PPE) and hygiene. The risk of reporting symptoms was analysed using logistic regression...... countries, small-scale farmers in Uganda do not use the most hazardous pesticides (WHO class 1a and 1b). However use of WHO class II pesticides and those of lower toxicity is seen in combination with inadequate knowledge and practice among the farmers. This poses a danger of acute intoxications, chronic...

  3. Pesticide Health and Safety Challenges Facing Informal Sector Workers: A Case of Small-scale Agricultural Workers in Tanzania.

    2016-08-01

    The Tanzania informal sector is growing fast, with precarious working conditions and particular hazards for women and children in agriculture. Hazardous agricultural chemicals including pesticides are mostly imported and have been used for many years. Despite the role played by pesticides in food security and vector control, these chemicals are responsible for acute and chronic illnesses among communities. The availability of obsolete persistent organic pesticides on the open market indicates existence of an inadequate regulatory system. People who get injured or ill in the agriculture sector in Tanzania receive health services in primary health care facilities where professionals have little or no knowledge of pesticides. We are presenting the pesticide health and safety challenges faced by small-scale farmers who fall in the informal sector. Achievements that have been made by the government and other players to reduce and prevent pesticide exposures and poisoning are also outlined. PMID:27406110

  4. Carbon monoxide poisoning

    Dolan, Michael C.

    1985-01-01

    Carbon monoxide poisoning is a significant cause of illness and death. Its protean symptoms probably lead to a gross underestimation of its true incidence. Low levels of carbon monoxide aggravate chronic cardiopulmonary problems, and high levels are associated with cardiac arrhythmias and cerebral edema. Patients who survive acute poisoning are at risk of delayed neurologic sequelae. The measurement of carboxyhemoglobin levels does not reveal the tissue levels of carbon monoxide but is useful...

    The global problem of acute poisoning has steadily increased over the past few years. It is an important cause of morbidity and mortality in developing countries. Better preventive and management strategies can be developed if the incidence and pattern of acute poisoning is known. The study aims at analyzing the pattern, cause and mortality rate of poisoning. The study was conducted in a rural area in South India. This retrospective study was conducted from January 2003-December 2003. The data was analysed using descriptive statistics. Out of the 225 cases 139 were males and 86 females. Poisoning was common in the age group of 21-30 years which was 84 cases and 11-20 years was 73 cases. The poisons consumed were as follows: Organophosphorous 135 cases, aluminum and zinc phosphide 50 cases, phenobarbitone 18 cases, benzodiazepines 7 cases, paracetamol 2 cases, miscellaneous 13 cases. 94% were suicides and 6% accidental. Mortality rate was 12.8%. Establishment of strict policies against the sale and availability of pesticides and over the counter drugs is an effective way to control organophosphorous and drug poisoning. PMID:21036199

  6. Pesticide exposure - Indian scene

    Use of pesticides in India began in 1948 when DDT was imported for malaria control and BHC for locust control. India started pesticide production with manufacturing plant for DDT and benzene hexachloride (BHC) (HCH) in the year 1952. In 1958, India was producing over 5000 metric tonnes of pesticides. Currently, there are approximately 145 pesticides registered for use, and production has increased to approximately 85,000 metric tonnes. Rampant use of these chemicals has given rise to several short-term and long-term adverse effects of these chemicals. The first report of poisoning due to pesticides in India came from Kerala in 1958 where, over 100 people died after consuming wheat flour contaminated with parathion. Subsequently several cases of pesticide-poisoning including the Bhopal disaster have been reported. Despite the fact that the consumption of pesticides in India is still very low, about 0.5 kg/ha of pesticides against 6.60 and 12.0 kg/ha in Korea and Japan, respectively, there has been a widespread contamination of food commodities with pesticide residues, basically due to non-judicious use of pesticides. In India, 51% of food commodities are contaminated with pesticide residues and out of these, 20% have pesticides residues above the maximum residue level values on a worldwide basis. It has been observed that their long-term, low-dose exposure are increasingly linked to human health effects such as immune-suppression, hormone disruption, diminished intelligence, reproductive abnormalities, and cancer. In this light, problems of pesticide safety, regulation of pesticide use, use of biotechnology, and biopesticides, and use of pesticides obtained from natural plant sources such as neem extracts are some of the future strategies for minimizing human exposure to pesticides

  7. Acute and sublethal effects of sequential exposure to the pesticide azinphos-methyl on juvenile earthworms (Eisenia andrei).

    2012-04-01

    The use of organophosphate pesticides is an integral part of commercial farming activities and these substances have been implicated as a major source of environmental contamination and may impact on a range of non-target fauna. The extent to which soil dwelling non-target organisms are affected by exposure to the organophosphate azinphos-methyl was investigated through monitoring selected biomarker responses and life cycle effects under laboratory conditions in the earthworm Eisenia andrei. Standard acute toxicity tests were conducted followed by a sequential exposure regime experiment, in order to assess the effects of multiple pesticide applications on biomarker (cholinesterase activity and neutral red retention time), life-cycle (growth and reproduction) and behaviour (avoidance and burrowing activity) responses. The present study indicates that the time between exposure events was a more important variable than concentration and that a longer interval between exposures may mitigate the effects of pesticide exposure provided that the exposure concentration is low. Additionally, it was shown that E. andrei was unable to avoid the presence of azinphos-methyl in soil, even at concentrations as high as 50% of the LC(50) value, indicating that the presence of azinphos-methyl in the soil pose a realistic threat to earthworms and other soil dwelling organisms. The ChE inhibition test showed a high percentage inhibition of the enzyme in all exposure groups that survived and NRR times of exposed organisms were lower than that of the controls. The present study yielded important results that contribute to the understanding of biological impacts of pesticide pollution on the environment. Extrapolating these results can aid in optimising pesticide application regimes to mitigate the environmental effects thereof and thus ensuring sustained soil biodiversity in agricultural areas.

    2013-04-01

    Full Text Available Arsine is one of the most potent hemolytic agents. It is important to clarify arsine metabolism as well as its chemical interactions with biological components. The aim of the present study was to clarify arsine metabolism by arsenic speciation analysis in serum and urine from an acute poisoning patient with hematuria, anemia, and renal and liver dysfunction. Speciation analysis of arsenics in serum and urine was performed using HPLC-ICP-MS. The total arsenic (T-As concentration in serum was 244.8 μg/l at admission and 97.1 μg/l at discharge. In the speciation analysis, four kinds of As compounds derived from arsine metabolism were detected in serum and urine. The concentration of arsenite (AsIII, arsenate (AsV, monomethylarsonic acid (MMA, and dimethylarsinic acid (DMA in serum at admission were 45.8, 5.2, 17.9 and 9.3 μg/l, respectively. The concentrations of AsIII, AsV, and MMA decreased with biological half time (BHT of 30.1, 43.0, and 96.3 h, respectively. Only DMA was increased at discharge. The urinary AsIII, AsV, MMA and DMA concentrations were 223.0, 12.1, 317.5 and 1053.5 μg/l at discharge, and decreased with BHT of 15.1, 20.8, 14.7, and 16.0 d, respectively. The results indicate that arsine was quickly metabolized to AsIII and subsequently up to DMA, with the result that the toxic effects of inorganic arsenic were added to those of arsine toxicity.

  9. Sampling strategies for estimating acute and chronic exposures of pesticides in streams

    Crawford, Charles G.

    2004-01-01

    The Food Quality Protection Act of 1996 requires that human exposure to pesticides through drinking water be considered when establishing pesticide tolerances in food. Several systematic and seasonally weighted systematic sampling strategies for estimating pesticide concentrations in surface water were evaluated through Monte Carlo simulation, using intensive datasets from four sites in northwestern Ohio. The number of samples for the strategies ranged from 4 to 120 per year. Sampling strategies with a minimal sampling frequency outside the growing season can be used for estimating time weighted mean and percentile concentrations of pesticides with little loss of accuracy and precision, compared to strategies with the same sampling frequency year round. Less frequent sampling strategies can be used at large sites. A sampling frequency of 10 times monthly during the pesticide runoff period at a 90 km 2 basin and four times monthly at a 16,400 km2 basin provided estimates of the time weighted mean, 90th, 95th, and 99th percentile concentrations that fell within 50 percent of the true value virtually all of the time. By taking into account basin size and the periodic nature of pesticide runoff, costs of obtaining estimates of time weighted mean and percentile pesticide concentrations can be minimized.

    Full Text Available Abstract Background Acute poisoning with organophosphorus compounds (OPs is a major global clinical problem in the developing countries. There have been many animal studies and few human surveys on the effects of organophosphorus pesticide (OP poisoning on thermoregulation. The aim of this prospective study was to document the pattern of tympanic temperature changes among OP poisoned patients throughout the length of their hospital stay. Methods 60 patients with diagnose of organophosphate poisoning were included in this study. Questioner was filled out by trained nurses including demographic, clinical and paraclinical data. Tympanic temperature and Pulse rate data of the cases were collected on five- occasions after admission. Results There were 41 (68.3% male and 19 (31.7% female, with a mean age of 34.4 ±19.4 years (range 13–89 years. Forty five patients had intentional poisoning for suicidal attempt. At the time of entry, the mean tympanic temperature, pulse rate, respiratory rate and blood pressure (systolic and diastolic of the OP poisoned patients were respectively 37.1+/−0.6°C (36.0- 39.5, 91+/−18 (55–145, 18+/−5.6 (8–44, 116+/−20 mm Hg (70–170 and 75+/−11.6 mm Hg (40–110. 41.7% of the cases had serum butyryl cholinesterase activities (BChE ≥ 50% normal (≥1600 mU/ml. Our patients had normal temperature at the time entry (mean = 37.1. Tympanic temperature decreasing below 36°C was not detected among the patients during the study period. A rise in mean tympanic temperature was found after atropine administration. Conclusion Our study showed hypothermia was not considerable factor among organophosphate poisoned patients, although more studies with similar situations in tropical countries are needed.

  15. The diagnostic value of apparent diffusion coefficient value on the delayed encephalopathy after acute carbon monoxide poisoning

    Objective: To investigate the diagnostic value of ADC on delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods: Forty healthy subjects with normal head MRI appearance and 32 cases with DEACMP were recruited and scanned using MRI. ADC values in bilateral globus pallidus, cerebral white matter (peri-ventricle, centrum semioval) and cortex were measured respectively. According to conventional MRI, 32 DEACMP patients were divided into abnormal and normal signal intensity groups, and followed up more than one year. Thirteen cases without evident symptoms and 3 cases with little headache and dizziness were good prognosis group. Fifteen cases with disturbance of intelligence and mental anomaly and one case with manifested unresponsive, inability in life self-care, urinary and fecal incontinence were poor prognosis group. Independent samples t-test was used to compared all parts of brain ADC values between DEACMP group and normal control, abnormal and normal signal intensity groups, normal signal intensity group and normal control, good and poor prognosis groups. Results: According to MRI findings, DEACMP were classified into three types: type 1: showing white matter involvement; type 2: showing neural nuclei involvement and type 3: showing brain cortex involvement. The ADC values [peri-ventricle white matter (0.62±0.06) x 10-3 mm2/s, the globus pallidus (0.67± 0.05) x 10-3 mm2/s, centrum semioval(0.57±0.07) x 10-3 mm2/s] in DEACMP group were statistically different with those [(0.74±0.03) x 10-3, (0.74±0.04) x 10-3, (0.73±0.05) x 10-3 mm2/s] in normal people (t=2.82,2.89,2.98, P-3 mm2/s, centrum semioval(0.52±0.09) x 10-3 mm2/s] in 20 cases with abnormal signal on routine MRI were statistically different with the ADC values [(0.66±0.05) x 10-3, (0.62±0.06) x 10-3 mm2/s] in 12 cases without abnormal signal (t=4.45,3.98, P-3 mm2/s, centrum semioval (0.58±0.05) x 10-3 mm2/s] in good prognosis group, the ADC value of 16 cases [(0.56±0.02) x

  16. Poison control services in China

    The following aspects are discussed: the public health problems of acute poisoning in China in recent years; the characteristics of acute poisoning; the negative effects of poison cases on the society and economy. The four stages of development of a poison control system in China are: (1) clinical hospital as the only facility used for detoxification; (2) institutes and hospitals of occupational medicine got involved in the program; (3) the traditional model of poison control changed to the modern National Poison Control Center (NPCC), and its network got established and it began to play a key role; (4) establishment of a multi-disciplinary network for dealing with emergencies in which chemical poison control is an important component. Introduction of the operations of the NPCC: the functions of the center are a 24 h hotline service, clinical consultants service, poison identification and diagnosis, laboratory analysis, education for public, training for physicians, coordination of anti-dotes, and the development of a network of poison control centers for dealing with chemical emergencies. The work practice and achievement of NPCC and its network in the field of poison control during the last 3 years is discussed. Lessons from SARS infection: to extend the network, to strengthen multi-disciplinary cooperation, enhance communication between centers, to pay attention to capacity building, to improve reporting systems, and to share resources

  17. Acute toxic effects of three pesticides on Pseudomonas putida monitored by microcalorimeter.

    Chen, Hui-Lun; Yao, Jun; Wang, Fei; Bramanti, Emilia; Maskow, Thomas; Zaray, Gyula

    2009-02-01

    A series of calorimetric experiments were performed to investigate the toxic effects of beta-cypermethrin (BCP), bensulfuron-methyl (BSM) and prometryne (PM) on Pseudomonas putida (P. putida). The metabolic action of P. putida on the three pesticides was studied by obtaining power-time curves. The growth of P. putida was inhibited completely in each case when the concentrations of pesticides were up to 80 micro g mL(- 1). The relationships between the inhibitory ratio (k) and doses of contaminants were approximately linear for the three pesticides. The total heat dissipated per milliliter (Q(total)) for the pesticides decreased during the course of the experiment. The OD(600) of P. putida growth in the absence and presence of pesticides was also obtained. The power-time curves of P. putida growth coincided with its turbidity curves. This elucidates that microcalorimetric method agrees well with the routine microbiological method. Among these three pesticides, BSM was found to be the most toxic with an IC(50) of 19.24 micro g mL(- 1) against P. putida. PM exhibited moderate virulence with an IC(50) of 27.86 micro g mL(- 1) and BCP had the lowest toxicity with an IC(50) of 39.64 micro g mL(- 1). PMID:19130374

  10. Assessment of acute pesticide toxicity with selected biochemical variables in suicide attempting subjects

    Pesticide induced changes were assessed in thirty two subjects of attempted suicide cases. Among all, the farmers and their families were recorded as most frequently suicide attempting. The values obtained from seven biochemical variables of 29 years old (average age) hospitalized subjects were compared to the same number and age matched normal volunteers. The results revealed major differences in the mean values of the selected parameters. The mean difference calculate; alkaline phosphatase (178.7 mu/l), Bilirubin (7.5 mg/dl), GPT (59.2 mu/l) and glucose (38.6 mg/dl) were higher than the controls, which indicate the hepatotoxicity induced by the pesticides in suicide attempting individuals. Increase in serum creatinine and urea indicated renal malfunction that could be linked with pesticide induced nephrotoxicity among them. (author)

    The aim of the study was to determine whether serum ischemia-modified albumin (IMA) levels in patients with carbon monoxide (CO) poisoning were higher compared with a control group of healthy volunteers. In addition, the study sought to determine if there was a correlation between serum IMA levels and carboxyhemoglobin (COHB) levels and other critical neurological findings (CNFs). In this prospective study, the IMA levels of 100 patients with CO poisoning and 50 control individuals were compared. In addition, the IMA and COHB levels were analyzed according to absence or presence CNFs in patients with CO poisoning. The levels of IMA (mg/dL) on admittance, and during the 1(st) hour and 3(rd) hour, in patients with CO poisoning (49.90 ± 35.43, 30.21 ± 14.81, and 21.87 ± 6.03) were significantly higher, compared with the control individuals (17.30 ± 2.88). The levels of IMA in the 6(th) hour were not higher compared with control individuals. The levels of IMA on admittance, and during the 1(st) hour, 3(rd) hour, and 6(th) hour, and COHB (%) levels in patients who had CNFs were higher compared with IMA levels and COHB levels in patients who had no CNFs (p < 0.001). However, when the multivariate model was created, it was observed that IMA level on admittance was a poor indicator for prediction of CNFs (odds ratio = 1.05; 95% confidence interval, 1.01-1.08). We therefore concluded that serum IMA levels could be helpful in the diagnosis of CO poisoning. However, we believe that IMA levels cannot be used to predict which patients will develop CNFs due to CO poisoning. PMID:27185603

    Full Text Available Abstract Background The case fatality for intentional self-poisoning in rural Asia is 10–30 times higher than in the West, mostly due to the use of highly toxic poisons. Activated charcoal is a widely available intervention that may – if given early – bind to poisons in the stomach and prevent their absorption. Current guidelines recommend giving a single dose of charcoal (SDAC if patients arrive within an hour of ingestion. Multiple doses (MDAC may increase poison elimination at a later time by interrupting any enterohepatic or enterovascular circulations. The effectiveness of SDAC or MDAC is unknown. Since most patients present to hospital after one hour, we considered MDAC to have a higher likelihood of clinical benefit and set up a study to compare MDAC with no charcoal. A third arm of SDAC was added to help determine whether any benefit noted from MDAC resulted from the first dose or all doses. Methods/design We set up a randomised controlled trial assessing the effectiveness of superactivated charcoal in unselected adult self-poisoning patients admitted to the adult medical wards of three Sri Lankan secondary hospitals. Patients were randomised to standard treatment or standard treatment plus either a single 50 g dose of superactivated charcoal dissolved in 300 ml of water or six doses every four hours. All patients with a history of poison ingestion were approached concerning the study and written informed consent taken from each patient, or their relative (for unconscious patients or those 72 hrs post-ingestion, and previous recruitment. The primary outcome was in-hospital mortality; secondary outcomes included the occurrence of serious complications (need for intubation, time requiring assisted ventilation, fits, cardiac dysrhythmias. Analysis will be on an intention-to-treat basis; the effects of reported time to treatment after poisoning and status on admission will also be assessed. Discussion This trial will provide important

    2010-01-01

    Full Text Available Pesticides are used extensively throughout the world in agriculture and in pest control as well as for community health purposes. Organophosphate (OP pesticide self-poisoning is an important clinical problem in rural regions of the developing world that kills an estimated 200,000 people every year. Unintentional poisoning kills far fewer people but is an apparent problem in places where highly toxic OP pesticides are available. Neurologic dysfunction is the best documented health effect of pesticide exposure. High-level exposure has both acute and long-term neurologic signs and symptoms, and adverse effects have been reported in most type of pesticides, including organophosphate (OP, carbamate, organochlorine, and pyrethroid insecticides, herbicides, fungicides, and fumigants. Acute OP pesticide exposure can involve in wide range of both central and peripheral neurologic symptoms. Increased neurologic symptom prevalence may provide early evidence of neurologic dysfunctions, before clinically measurable signs are evident. In this study, we analyzed the cross-sectional data on neurologic signs and symptoms from 225 rural children, both males (n = 132 and females (n = 93 who were occupationally and paraoccupationally exposed to methyl OPs (dichlorvos, fenthion, malathion, methyl parathion and ethyl OPs (chlorpyrifos, diazinon, ethyl parathion as they belonged to agricultural families handling, mixing, and spraying the OP pesticides. The children completed a specially designed questionnaire (Q16 on neurologic symptoms associated with pesticide exposure with their parental help. A suitable reference group consisting of rural children (n = 50 never involved in pesticide handling (neither outdoor nor indoor belonging to similar socioeconomic strata included in the study to compare the prevalence of various neurologic symptoms between the two groups. Among all the neurologic self-reported symptoms, headache, watering in eyes, and burning sensation in

  19. Is plasma β-glucuronidase a novel human biomarker for monitoring anticholinesterase pesticides exposure? A Malaysian experience

    A cross-sectional study was conducted to investigate the effects of acute and chronic pesticide exposure on the plasma β-glucuronidase enzyme activity among five patients of acute pesticide poisoning in Tengku Ampuan Rahimah Hospital, Klang, 230 farmers in the MADA area, Kedah and 49 fishermen in Setiu, Terengganu. The duration of pesticide exposure among the patients was unknown, but the plasma samples from patients were collected on day one in the hospital. The duration of pesticide exposure among the farmers was between 1 and 45 years. The β-glucuronidase activity was compared with plasma cholinesterase activity in the same individual. The plasma cholinesterase activity was measured using Cholinesterase (PTC) Reagent set kit (Teco Diagnostics, UK) based on colorimetric method, while the plasma β-glucuronidase activity was measured fluorometrically based on β-glucuronidase assay. The plasma cholinesterase activity was significantly reduced (p 0.05). The plasma β-glucuronidase activity among the farmers was significantly elevated (p 0.05). The plasma cholinesterase activity was positively correlated with the plasma β-glucuronidase activity among the farmers (r = 0.205, p 0.05). Thus, plasma β-glucuronidase enzyme activity can be measured as a biomarker for the chronic exposure of pesticide. However, further studies need to be performed to confirm whether plasma β-glucuronidase can be a sensitive biomarker for anticholinesterase pesticide poisoning

    2008-12-01

    Full Text Available Unintentional poisoning occurred mainly among children. The leading cause of such poisoning in Brazil, among consumer products was household cleaning products. For this study 2810 calls made to two poison control centers in the State of Rio de Janeiro between January 2000 and December 2002 were analyzed. Children under five were the most vulnerable group. More boys under 10 suffered accidental poisoning than girls, although above this age, the distribution was inverted. The calls received by poison control centers were mainly from health services within the first two hours following poisoning. The most frequent exposure routes were ingestion (90.4%, followed by inhalation (4.3%, skin and eye contact (2.4% and 2% respectively. The products involved were bleach, petroleum derivates, rodenticides and pesticides. The main causes were products within the children's reach, storage in soft drink bottles, food mixed with rodenticides, incorrect product use, and kitchen utensils used for measured cleaning products. The most common outcome was that the patient was cured, although a lot of cases were lost to follow-up. Education programs are necessary in order to avoid these poisonings.Intoxicações não-intencionais ocorrem principalmente na infância.

    Objective In vivo Proton Magnetic Resonance Spectroscopy (1H-MRS) can be used to evaluate the levels of specific neurochemical biomarkers of pathological mechanisms in the brain. Methods We conducted T2-Weighted Magnetic Resonance Imaging (MRI) and 1H-MRS with a 3.0-Tesla animal MRI system to investigate the early microstructural and metabolic profiles in vivo in the striatum of rats following carbon monoxide (CO) poisoning. Results Compared to baseline, we found significant cortical surface deformation, cerebral edema changes, which were indicated by the unclear gray/white matter border, and lateral ventricular volume changes in the brain. A significant reduction in the metabolite to total creatine (Cr) ratios of N-acetylaspartate (NAA) was observed as early as 1 h after the last CO administration, while the lactate (Lac) levels increased marginally. Both the Lac/Cr and NAA/Cr ratios leveled off at 6 h and showed no subsequent significant changes. In addition, compared to the control, the choline (Cho)/Cr ratio was slightly reduced in the early stages and significantly increased after 6 h. In addition, a pathological examination revealed mild cerebral edema on cessation of the insult and more severe cerebral injury after additional CO poisoning. Conclusion The present study demonstrated that 1H-MRS of the brain identified early metabolic changes after CO poisoning. Notably, the relationship between the increased Cho/Cr ratio in the striatum and delayed neuropsychologic sequelae requires further research.

  9. Pesticide exposure--Indian scene.

    Gupta, P K

    2004-05-20

    Use of pesticides in India began in 1948 when DDT was imported for malaria control and BHC for locust control. India started pesticide production with manufacturing plant for DDT and benzene hexachloride (BHC) (HCH) in the year 1952. In 1958, India was producing over 5000 metric tonnes of pesticides. Currently, there are approximately 145 pesticides registered for use, and production has increased to approximately 85,000 metric tonnes. Rampant use of these chemicals has given rise to several short-term and long-term adverse effects of these chemicals. The first report of poisoning due to pesticides in India came from Kerala in 1958 where, over 100 people died after consuming wheat flour contaminated with parathion. Subsequently several cases of pesticide-poisoning including the Bhopal disaster have been reported. Despite the fact that the consumption of pesticides in India is still very low, about 0.5 kg/ha of pesticides against 6.60 and 12.0 kg/ha in Korea and Japan, respectively, there has been a widespread contamination of food commodities with pesticide residues, basically due to non-judicious use of pesticides. In India, 51% of food commodities are contaminated with pesticide residues and out of these, 20% have pesticides residues above the maximum residue level values on a worldwide basis. It has been observed that their long-term, low-dose exposure are increasingly linked to human health effects such as immune-suppression, hormone disruption, diminished intelligence, reproductive abnormalities, and cancer. In this light, problems of pesticide safety, regulation of pesticide use, use of biotechnology, and biopesticides, and use of pesticides obtained from natural plant sources such as neem extracts are some of the future strategies for minimizing human exposure to pesticides.

    2016-03-01

    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.

    conflitantes, não permitindo concluir se a coagulação intravascular disseminada tem participação na patogênese das hemorragias nessa intoxicação. A citopatologia e histopatologia da medula óssea dos quatro bovinos intoxicados revelaram acentuada diminuição no número de células hematopoéticas das três linhagens medulares, caracterizando insuficiência medular por aplasia; conclui-se que apenas eventos da hemostasia primária devidos a trombocitopenia são responsáveis pelas hemorragias. Na hemocultura de três dos bovinos intoxicados houve crescimento de Klebsiella oxytoca, Staphylococcus hyicus e Staphylococcus aureus, indicando que a septicemia, facilitada pela neutropenia, pode ter participação na causa da morte de bovinos na intoxicação aguda pela ingestão de P. aquilinum. Aspectos adicionais de interesse na reprodução da intoxicação aguda por samambaia em bovinos deste relato incluem o desenvolvimento de hematúria na doença aguda e a apresentação da chamada forma laríngea da doença.This experiment was design to address the following points in relation to the acute poisoning by bracken fern (Pteridium aquilinum in cattle: 1 the severity of the thrombocytopenia in different stages of the intoxication and its relationship to possible deficits in the secondary hemostasis, 2 the relationship between neutropenia and the morphological signs of septicemia occasionally found at necropsy, and 3 the mechanism of anemia and its relationship with blood loss, medium life of erythrocytes and the progress of the disease. The fresh green upper parts of P. aquilinum were fed to four mixed breed calves with average age of 18 months and weights ranging from 190 to 215 kg. A calf of similar age and weight was kept together with the other four under the same conditions, except for the ingestion of P. aquilinum. The four fern-fed calves died with typical features of acute bracken fern poisoning after being fed with the plant for 53-58 days daily doses of 8.0, 8

    Epidemiologic data on acute chemical poisonings in South Caucasus region are extremely limited. The purpose of this joint prospective study was evaluation and analyzes the rate and characteristics of acute chemical poisoning cases in Azerbaijan and Georgia. This investigation was performed on data of poisoned patients admitted to Republican Toxicology Center of Ministry of Health of Azerbaijan in Baku city and poisoned patients admitted to medical hospitals in Tbilisi (Georgia) from 1st January to 31st December, 2007. Total were 1182 hospitalizations in Republican Toxicology Center's (RTC) intensive care unit and 1646 poisoned patients admitted to medical hospitals in Tbilisi (Georgia). The mean lengths of hospitalization were 3.2 days in Azerbaijan and 1.2 days in Georgia. Acute intoxications were more frequent amount males (51% in Azerbaijan to 67% in Georgia) and in 20-40 age group. Among the pharmaceuticals poisonings by antiepileptic, sedative-hypnotic and antiparkinsonism drugs (T42) and poisonings by psychotropic drugs (T43) were the most frequent. The other cases of poisonings were inhalation of carbon monoxide (T58) - 173 hospitalization in Azerbaijan and 77 hospitalization in Georgia; toxic effect of alcohol (T51) - 50 admissions in Azerbaijan and 697 admissions in Georgia; poisoning by narcotics and psychodysleptics (T40) - 50 cases in Azerbaijan and 36 cases in Georgia; toxic effect of corrosive substances (T54) 176 patients in Azerbaijan to 56 patients in Georgia; toxic effect of pesticides (T60) - 39 patients in Azerbaijan to 11 patients in Georgia; toxic effect of contact with venomous animals (T63) - 70 patients in Azerbaijan to 23 patients in Georgia and toxic effect of other noxious substances eaten as food (T62) - 7 patients in Azerbaijan to 85 patients in Georgia The mortality rates were 3.1% in Azerbaijan and 0.74% in Georgia. Corrosive liquids (especially - concentrated acetic acid) poisonings were most often fatal (41% of total mortality) in

    2015-03-01

    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. PMID:26753326

    [Aims] Honey bee is one of the most important insects for plant pollination, but the honey bees are underlying the phenomenon of colony collapse disorder (CCD), one of the factors causing this problem is the much use of pesticides in agricultural production. Totally 300 pesticides were tested for their acute omi toxicity to honey bee (Apis mellifera) by dietary method in the paper, the objective of this study is to understand the status of toxicity of common used pesticides.[Restults] The results indicated that the pesticides with very high toxicity, high toxicity, moderate toxicity and low toxicity pesticides accounted for 14.7, 35.6, 10.7, 39% respectively, the high toxic and very high toxic pesticide covered more than 50%, and these pesticides were mainly the insecticides, while the fungicides and herbicides with relative low toxicity.The toxicity of different pesticide formulations with the same active ingredients (AI) to zebra fish maybe varied for the difference in AI content, formulation type and processing technique. Regarding to the biological pesticides, some of them still have high toxicity to honeybee. [Conclusions] These results suggested that the pesticides with high toxicity to honey bee covered a large proportion of common used pesticides in China, therefore, some precautions should be involved as we used the pesticides, particularly for insecticides to reduce or avoid the side effects on honey bee.%[目的]蜜蜂是一种重要的传粉昆虫,近年来世界各地出现了严重的种群衰退现象,原因之一是农业生产过程中使用了大量农药.采用摄入法测定f300个农药制剂对蜜蜂的急性经口毒性,旨在了解我国常用农药对蜜蜂的毒风险情况.[结果]结果表明:对蜜蜂的急性经口毒性表现剧毒、高毒、中毒、低毒的农药制剂分别占14.7%、35.6%、10.7%、39%,高毒和剧毒农药产品达50%以上,但这些制剂主要为杀虫剂,占整个杀虫剂的74.1%,杀菌剂和除草剂

    Hyperbaric oxygen therapy is the primary treatment for arterial gas embolism, decompression sickness and acute carbon monoxide poisoning. Though there has been a proliferation of hyperbaric centers throughout the United States, a scarcity of centers equipped to treat emergency indications makes transport of patients necessary. To locate and characterize hyperbaric chambers capable of treating emergency cases, a survey of centers throughout the entire United States was conducted. Using Google, Yahoo, HyperbaricLink and the UHMS directory, a database for United States chambers was created. Four researchers called clinicians from the database to administer the survey. All centers were contacted for response until four calls went unreturned or a center declined to be included. The survey assessed chamber readiness to respond to high-acuity patients, including staff availability, use of medical equipment such as ventilators and intravenous infusion devices, and responding yes to treating hyperbaric emergencies within a 12-month period. Only 43 (11.9%, N = 361) centers had equipment, intravenous infusion pumps and ventilators, and staff necessary to treat high-acuity patients. Considering that a primary purpose of hyperbaric oxygen therapy is the treatment of arterial gas embolism and decompression sickness, more hyperbaric centers nationwide should be able to accommodate these emergency cases quickly and safely.

    Among the human pathologies produced by venomous animals, bee stings constitute the largest number of accidents in several countries, exceeding the mortality rate caused by other venomous animals such as snakes, spiders or scorpions. The clinical picture after the bee sting may include anaphylaxis or poisoning. The latter is produced by massive attacks and is a serious problem that may put the patient's life at risk. People that are poisoned display hemolysis, rhabdomiolysis and acute renal failure that together with other systemic failures can bring about death. The knowledge of the physiopathological mechanisms involved in the massive attack of bees is crucial for health care professionals as to date we do not have antivenoms with proven clinical efficacy. In this review we include the bee's biological aspects, venom composition and its relation with the occurrence and severity of accidents as well as epidemiological data that can be useful for this type of accidents.

  19. Benzodiazepine poisoning in elderly

    Perković-Vukčević Nataša

    2016-01-01

    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.

  3. Acute Poisonings from Synthetic Cannabinoids - 50 U.S. Toxicology Investigators Consortium Registry Sites, 2010-2015.

    Riederer, Anne M; Campleman, Sharan L; Carlson, Robert G; Boyer, Edward W; Manini, Alex F; Wax, Paul M; Brent, Jeffrey A

    2016-01-01

    Recent reports suggest that acute intoxications by synthetic cannabinoids are increasing in the United States (1,2). Synthetic cannabinoids, which were research compounds in the 1980s, are now produced overseas; the first shipment recognized to contain synthetic cannabinoids was seized at a U.S. border in 2008 (3). Fifteen synthetic cannabinoids are Schedule I controlled substances (3), but enforcement is hampered by the continual introduction of new chemical compounds (1,3). Studies of synthetic cannabinoids indicate higher cannabinoid receptor binding affinities, effects two to 100 times more potent than Δ(9)-tetrahydrocannabinol (the principal psychoactive constituent of cannabis), noncannabinoid receptor binding, and genotoxicity (4,5). Acute synthetic cannabinoid exposure reportedly causes a range of mild to severe neuropsychiatric, cardiovascular, renal, and other effects (4,6,7); chronic use might lead to psychosis (6,8). During 2010-2015, physicians in the Toxicology Investigators Consortium (ToxIC) treated 456 patients for synthetic cannabinoid intoxications; 277 of the 456 patients reported synthetic cannabinoids as the sole toxicologic agent. Among these 277 patients, the most common clinical signs of intoxication were neurologic (agitation, central nervous system depression/coma, and delirium/toxic psychosis). Relative to all cases logged by 50 different sites in the ToxIC Case Registry, there was a statistically significant association between reporting year and the annual proportion of synthetic cannabinoid cases. In 2015, reported cases of synthetic cannabinoid intoxication increased at several ToxIC sites, corroborating reported upward trends in the numbers of such cases (1,2) and underscoring the need for prevention.

  6. Glyphosate poisoning.

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

    2004-01-01

    Glyphosate is used extensively as a non-selective herbicide by both professional applicators and consumers and its use is likely to increase further as it is one of the first herbicides against which crops have been genetically modified to increase their tolerance. Commercial glyphosate-based formulations most commonly range from concentrates containing 41% or more glyphosate to 1% glyphosate formulations marketed for domestic use. They generally consist of an aqueous mixture of the isopropylamine (IPA) salt of glyphosate, a surfactant, and various minor components including anti-foaming and colour agents, biocides and inorganic ions to produce pH adjustment. The mechanisms of toxicity of glyphosate formulations are complicated. Not only is glyphosate used as five different salts but commercial formulations of it contain surfactants, which vary in nature and concentration. As a result, human poisoning with this herbicide is not with the active ingredient alone but with complex and variable mixtures. Therefore, It is difficult to separate the toxicity of glyphosate from that of the formulation as a whole or to determine the contribution of surfactants to overall toxicity. Experimental studies suggest that the toxicity of the surfactant, polyoxyethyleneamine (POEA), is greater than the toxicity of glyphosate alone and commercial formulations alone. There is insufficient evidence to conclude that glyphosate preparations containing POEA are more toxic than those containing alternative surfactants. Although surfactants probably contribute to the acute toxicity of glyphosate formulations, the weight of evidence is against surfactants potentiating the toxicity of glyphosate. Accidental ingestion of glyphosate formulations is generally associated with only mild, transient, gastrointestinal features. Most reported cases have followed the deliberate ingestion of the concentrated formulation of Roundup (The use of trade names is for product identification purposes only and

  12. Comparison of two pre-exposure treatment regimens in acute organophosphate (paraoxon) poisoning in rats: Tiapride vs. pyridostigmine

    Recently, the FDA approved the medical use of oral pyridostigmine as prophylactic treatment of possible nerve agent exposure: the concept is to block the cholinesterase transitorily using the carbamate (pyridostigmine) in order to deny access to the active site of the enzyme to the irreversible inhibitor (nerve agent) on subsequent exposure. We have shown previously that tiapride is in vitro a weak inhibitor of acetylcholinesterase and that in rats administration of tiapride before the organophosphate paraoxon significantly decreases mortality. The purpose of the present study was to compare tiapride- and pyridostigmine-based pretreatment strategies, either alone or in combination with pralidoxime reactivation, by using a prospective, non-blinded study in a rat model of acute high-dose paraoxon exposure. Groups 1-6 received 1 μMol paraoxon (∼ LD75) groups 2-6 received in addition: G2 50 μMol tiapride 30 min before paraoxon; G3 50 μMol tiapride 30 min before paraoxon and 50 μMol pralidoxime 1 min after paraoxon; G4 1 μMol pyridostigmine 30 min before paraoxon; G5 1 μMol pyridostigmine 30 min before paraoxon and 50 μMol pralidoxime 1 min after paraoxon; G6 50 μMol pralidoxime 1 min after paraoxon; Mortality data were compared using Kaplan-Meier plots and logrank tests. Mortality is statistically significantly influenced by all treatment strategies. Tiapride pretreatment followed by pralidoxime treatment (G3) is aux par with pyridostigmine pretreatment followed by pralidoxime treatment (G5). Tiapride pretreatment only (G2) is inferior to pyridostigmine pretreatment only (G4). The best results are achieved with pyridostigmine pretreatment only or pralidoxime treatment only (G4 and G6)

Methods This hospital based descriptive study of first 100 patients from both sexes who presented to Pediatric department, CHK from 1st January 2006 till 31st December 2008 with exposure to a known poisonous agent and fulfilling other inclusion criteria were included in the study. Data regarding their demographic profile and potential risk factors was collected on a well structured proforma, cases were followed until discharge or expiry. Data was analyzed using frequencies, proportions, group means, median and standard deviations. Results The male to female ratio in our study was 1.2:1, with kerosene (50% being the most common household agent followed by medicines (38%, insecticides (7% and bathroom cleaners (5%. Factors such as mother's education level, number of siblings and storage place of poison correlated significantly with the cases of accidental poisoning. Most of the children (70% presented within 3 hours of ingestion. Dyspnea was the most common symptom observed. The mortality rate in our study was 3%. Conclusions Children belonging to age group 2-3 years are the most susceptible both in terms of morbidity and mortality. Preventive strategies need to be adopted at a national level to spread awareness among parents.

    Pesticides are frequently used substances worldwide, even when the use of some of them is forbidden due to the recognized adverse effect they have on the health of not only the people who apply the pesticides, but also of those that consume the contaminated products. The objectives of this study were to know the health issues of farm workers chronically exposed to pesticides, to evaluate possible damage at genetic level, as well as to explore some hepatic, renal, and hematological alterations. A transversal comparative study was performed between 2 groups, one composed of 25 farm workers engaged in pesticide spraying, and a control group of 21 workers not exposed to pesticides; both groups belonged to the Nextipac community in Jalisco, Mexico. Each member of both groups underwent a full medical history. Blood samples were taken from all farm workers in order to obtain a complete blood count and chemistry, clinical chemistry, lipid profile, liver and kidney function tests, erythrocyte cholinesterase quantification, lipid peroxidation profile, and free DNA fragment quantification. For the information analysis, central tendency and dispersion measurements were registered. In order to know the differences between groups, a cluster multivariate method was used, as well as prevalence reasons. The most used pesticides were mainly organophosphates, triazines and organochlorine compounds. The exposed group showed acute poisoning (20% of the cases) and diverse alterations of the digestive, neurological, respiratory, circulatory, dermatological, renal, and reproductive system probably associated to pesticide exposure. More importantly, they presented free DNA fragments in plasma (90.8 vs 49.05 ng/mL) as well as a higher level of lipid peroxidation (41.85 vs. 31.91 nmol/mL) in comparison with those data from unexposed farm workers. These results suggest that there exist health hazards for those farm workers exposed to pesticides, at organic and cellular levels. PMID:22315932

  9. Recent advances in evaluation of oxime efficacy in nerve agent poisoning by in vitro analysis

    The availability of highly toxic organophosphorus (OP) warfare agents (nerve agents) underlines the necessity for an effective medical treatment. Acute OP toxicity is primarily caused by inhibition of acetylcholinesterase (AChE). Reactivators (oximes) of inhibited AChE are a mainstay of treatment, however, the commercially available compounds, obidoxime and pralidoxime, are considered to be rather ineffective against various nerve agents, e.g. soman and cyclosarin. This led to the synthesis and investigation of numerous oximes in the past decades. Reactivation of OP-inhibited AChE is considered to be the most important reaction of oximes. Clinical data from studies with pesticide-poisoned patients support the assumption that the various reactions between AChE, OP and oxime, i.e. inhibition, reactivation and aging, can be investigated in vitro with human AChE. In contrast to animal experiments such in vitro studies with human tissue enable the evaluation of oxime efficacy without being affected by species differences. In the past few years numerous in vitro studies were performed by different groups with a large number of oximes and methods were developed for extrapolating in vitro data to different scenarios of human nerve agent poisoning. The present status in the evaluation of new oximes as antidotes against nerve agent poisoning will be discussed

  12. Pesticide acute toxicity is a better correlate of U.S. grassland bird declines than agricultural intensification.

    Pierre Mineau

    Full Text Available Common agricultural birds are in decline, both in Europe and in North America. Evidence from Europe suggests that agricultural intensification and, for some species, the indirect effects of pesticides mediated through a loss of insect food resource is in part responsible. On a state-by-state basis for the conterminous Unites States (U.S., we looked at several agronomic variables to predict the number of grassland species increasing or declining according to breeding bird surveys conducted between 1980 and 2003. Best predictors of species declines were the lethal risk from insecticide use modeled from pesticide impact studies, followed by the loss of cropped pasture. Loss of permanent pasture or simple measures of agricultural intensification such as the proportion of land under crop or the proportion of farmland treated with herbicides did not explain bird declines as well. Because the proportion of farmland treated with insecticides, and more particularly the lethal risk to birds from the use of current insecticides feature so prominently in the best models, this suggests that, in the U.S. at least, pesticide toxicity to birds should be considered as an important factor in grassland bird declines.

    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.

    Full Text Available Background: Organophosphorus (OP pesticides poisoning can result from occupational, accidental or intentional exposure. Clinical manifestations include cholinergic syndromes, central nervous (CNS system and cardiovascular disorders. Death is usually due to cardiovascular and respiratory failure. Aim: To evaluate various parameters that can predict outcome of patients in OP poisoning. Materials and Methods: A prospective study conducted in Department of Medicine, Adichunchingiri Institute Of medical Sciences and Research Centre, Karnataka, over period of 1 year. Diagnosis of OP poisoning was based on clinical history of exposure to OP compound and low serum pseudocholinesterase levels. Results: In the present study 133 patients were enrolled, out of which 98.5% were suicidal cases and only 1.5% had accidental exposure. Majority of cases were young male, with F/M ratio 1:3.2. Mortality rates were higher in younger people and in patients who required prolonged ventilator support. The mortality rate was directly proportional to amount of poison consumed, lag time, organ failure (Acute Renal Failure and plasma pseudocholinesterase levels. Acute complications were frequently noted and were related to morbidity and mortality. No strict relationship was found between liver dysfunction, electrolyte disturbance and clinical outcome. Conclusion: This case study concluded that mortality is directly proportionate to the lag time, amount of OP substances consumed, clinical severity, pseudocholinesterase levels, Acute renal failure and duration of ventilatory support. This study highlights the importance of rapid diagnosis, and initiation of early and effective treatment, which may result in less number complications and also decreases the mortality rates.

  17. A systematic review of aluminium phosphide poisoning.

    Mehrpour, Omid; Jafarzadeh, Mostafa; Abdollahi, Mohammad

    2012-03-01

    Every year, about 300,000 people die because of pesticide poisoning worldwide. The most common pesticide agents are organophosphates and phosphides, aluminium phosphide (AlP) in particular. AlP is known as a suicide poison that can easily be bought and has no effective antidote. Its toxicity results from the release of phosphine gas as the tablet gets into contact with moisture. Phosphine gas primarily affects the heart, lungs, gastrointestinal tract, and kidneys. Poisoning signs and symptoms include nausea, vomiting, restlessness, abdominal pain, palpitation, refractory shock, cardiac arrhythmias, pulmonary oedema, dyspnoea, cyanosis, and sensory alterations. Diagnosis is based on clinical suspicion, positive silver nitrate paper test to phosphine, and gastric aspirate and viscera biochemistry. Treatment includes early gastric lavage with potassium permanganate or a combination with coconut oil and sodium bicarbonate, administration of charcoal, and palliative care. Specific therapy includes intravenous magnesium sulphate and oral coconut oil. Moreover, acidosis can be treated with early intravenous administration of sodium bicarbonate, cardiogenic shock with fluid, vasopresor, and refractory cardiogenic shock with intra-aortic baloon pump or digoxin. Trimetazidine may also have a useful role in the treatment, because it can stop ventricular ectopic beats and bigeminy and preserve oxidative metabolism. This article reviews the epidemiological, toxicological, and clinical/pathological aspects of AlP poisoning and its management. PMID:22450207

  20. Pesticide illness, farm practices, and neurological symptoms among farm residents in Colorado

    The purpose of this study is to evaluate the association between pesticides and neurological symptoms among a population exposed to organophosphate chemicals as a result of agricultural use. Chronic squealed of acute pesticide poisoning from organophosphate compounds include a variety of neurological symptoms including restlessness, irritability, and trouble sleeping. Individuals who have had an acute pesticide poisoning have been reported to suffer a wide range of neurological symptoms that occur from weeks to months after the initial episode. Data for this study came from a cross-sectional survey of farmers and their spouses conducted in an eight-county area in northeastern Colorado. Neurological characteristics were assessed to determine their relationship with previously reported pesticide-related illnesses. Symptoms that were significantly associated with previous poisoning were difficulty concentrating [OR 2.07, 95% confidence interval (CI) 1.22, 3.50]; relatives noticing person had trouble remembering things (OR 2.54, 95% CI 1.47, 4.39); making notes to remember things (OR .18, 95% CI 1.20, 3.97); finding it hard to understand the meaning of newspapers, magazines, and books (OR 1.90, 95% CI 1.01, 3.60); felt irritable OR 1.84, 95% CI 1.08, 3.12); felt depressed (OR 2.82, 95% CI 1.65, 4.81); ad heart palpitations without exertion (OR 2.83, 95% CI 1.22, 6.54); sleeping more than usual (OR 3.58, 95% CI 1.95, 6.58); difficulty moving fingers or grasping things (OR 2.08, 95% CI 1.06, 3.24); and headaches at least once a week (OR 1.85, 95% CI 1.06, 3.24).

  7. [Poisoning in swine].

    Heinritzi, K

    1986-01-01

    For clinical interests it is advisable to subdivide cases of swine poisoning in such as caused by food, drugs and environmental poisonings. This division gives pointers to aetiologic connections and special measures necessary for the clearing of the processes. With food poisoning mycotoxicoses play an evermore important role, whereas poisonings by trace elements are on the decrease. Sodium chloride poisoning often results primarily from insufficient water supply. With environmental poisonings carbon monoxide and cyanamide intoxication are presented. Poisonings caused by drugs are mainly the result of an overdose, of segregation in food or of non-licensed drugs. A relatively unknown swine poisoning by a drug against coccidiosis--licensed for poultry--is described. PMID:2943054

  12. The effects of acute joint exposure to radiation and certain pesticides on the peripheric blood in rats

    The effect of joint external γ-radiation and some pesticides on the peripheric blood is studied. Lindane, trichlorfon and tetramethylthiuram disulfide are used as toxic chemicals. It is shown that the combined effect has caused, like radiation, stable leukopenia, but less expressed than the effect of gamma radiation. It is especially obvious in the case of combining ionizing radiation and TMTD when the number of leukocytes averaged by 25% more than in the case of injury by radiation alone. Lymphocytes are most sensitive blood cell elements earily responsing to radiation and chemical organism injuries, both qualitatively and quantitatively. The results of analyzing the dynamics of the most qualitative and quantitative paramaters of leukocytes permit to state the summation of mutual effects of factors of radiation and chemical nature

    1993-01-01

    A 65 year old patient admitted with carbon monoxide poisoning developed acute pulmonary oedema during treatment with hyperbaric oxygen. After initial recovery he developed extensive intestinal ischaemia which rapidly led to death. It is suggested that intestinal vasoconstriction due to left ventricular failure made the gut much more vulnerable to the hypoxic effects of carbon monoxide than the brain and heart.

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

    Gerstner, H.B.; Huff, J.E.

    1977-01-01

    Clinical aspects of mercury poisoning are described for elemental mercury, inorganic mercury compounds, and organic mercury compounds. Critical targets of poisoning by elemental mercury are the lungs and the central nervous system. A case of acute pulmonary injury and a case of chronic brain injury are described. The effects of inorganic mercury compounds are chiefly injuries to the alimentary canal and kidneys. Two cases of acute intoxication from these compounds are described. An epidemiologic study on Africans suffering from the nephrotic syndrome showed that aminomercuric chloride was the causative agent. Organic mercury compounds are discussed with regard to the following: individual cases of the methylmercury syndrome in adults; individual cases of prenatal methylmercury intoxication; epidemic outbreaks of methylmercury poisoning; epidemiology of methylmercury poisoning through dressed seed grain; and epidemic outbreaks of poisonings by organomercurials other than methylmercury.

  5. Acute toxicity of resmethrin, malathion and methoprene to larval and juvenile American lobsters (Homarus amemcanus) and analysis of pesticide levels in surface waters after Scourge™, Anvil™ and Altsoid™ application

    Zulkosky, Ann M.; Ruggieri, Joseph P.; Terracciano, Stephen A.; Brownawell, Bruce J.; McElroy, Anne E.

    2005-01-01

    Acute toxicity and immune response, combined with temperature stress effects, were evaluated in larval and juvenile American lobsters (Homarus americanus) exposed to malathion, resmethrin and methoprene. These pesticides were used to control West Nile virus in New York in 1999, the same year the American lobster population collapsed in western Long Island Sound (LIS). Whereas the suite of pesticides used for mosquito control changed in subsequent years, a field study was also conducted to determine pesticide concentrations in surface waters on Long Island and in LIS after operational applications. The commercial formulations used in 2002 and 2003—Scourge, Anvil and Altosid—contain the active ingredients resmethrin, sumithrin and methoprene, respectively. Concentrations of the synergist piperonyl butoxide (PBO) were also measured as a proxy for pesticide exposure. Acute mortality in Stage I-II larval lobsters demonstrated that they are extremely sensitive to continuous resmethrin exposure. Resmethrin LC50s for larval lobsters determined under flow-through conditions varied from 0.26–0.95 μg L−1 in 48- and 96-h experiments at 16°C, respectively. Increased temperature (24°C) did not significantly alter resmethrin toxicity. Malathion and methoprene were less toxic than resmethrin. The 48-h LC50 for malathion was 3.7 μg L−1 and methoprene showed no toxicity at the highest (10 μg L−1) concentration tested. Phenoloxidase activity was used as a measure of immune response for juvenile lobsters exposed to sublethal pesticide concentrations. In continuous exposures to sublethal doses of resmethrin (0.03 μg L−1) or malathion (1 μg L−1) for 7 d at 16 or 22°C, temperature had a significant effect on phenoloxidase activity (P ≤ 0.006) whereas pesticide exposure did not (P = 0.880). The analytical methods developed using high performance liquid chromatography coupled to time-of-flight mass spectroscopy (LC-TOF-MS) provided high sensitivity with mass

    Hanson, Niklas; Stark, John D

    2012-04-01

    Traditionally, ecological risk assessments (ERA) of pesticides have been based on risk ratios, where the predicted concentration of the chemical is compared to the concentration that causes biological effects. The concentration that causes biological effect is mostly determined from laboratory experiments using endpoints on the level of the individual (e.g., mortality and reproduction). However, the protection goals are mostly defined at the population level. To deal with the uncertainty in the necessary extrapolations, safety factors are used. Major disadvantages with this simplified approach is that it is difficult to relate a risk ratio to the environmental protection goals, and that the use of fixed safety factors can result in over- as well as underprotective assessments. To reduce uncertainty and increase value relevance in ERA, it has been argued that population models should be used more frequently. In the present study, we have used matrix population models for 3 daphnid species (Ceriodaphnia dubia, Daphnia magna, and D. pulex) to reduce uncertainty and increase value relevance in the ERA of a pesticide (spinosad). The survival rates in the models were reduced in accordance with data from traditional acute mortality tests. As no data on reproductive effects were available, the conservative assumption that no reproduction occurred during the exposure period was made. The models were used to calculate the minimum population size and the time to recovery. These endpoints can be related to the European Union (EU) protection goals for aquatic ecosystems in the vicinity of agricultural fields, which state that reversible population level effects are acceptable if there is recovery within an acceptable (undefined) time frame. The results of the population models were compared to the acceptable (according to EU documents) toxicity exposure ratio (TER) that was based on the same data. At the acceptable TER, which was based on the most sensitive species (C. dubia

  10. Methodology for determining toxicity of pesticides to wild vertebrates

    DeWitt, James B.

    1966-01-01

    The effects of pesticidal contamination of wildlife habitats may be expected to be proportional to the toxicity of the compounds, the rate and manner of application, persistence of the basic chemical and/or any toxic metabolites, and the extent to which these substances are stored in animal tissues or concentrated by successive elements of wildlife food chains. Measurement of these effects under field conditions is difficult, but the need for field studies may be reduced or eliminated by controlled laboratory tests. Representatives of the birds, mammals and aquatic animals in treated areas should be examined at all stages in the life cycle. Suitable species include laboratory rats, rabbits, dogs, bobwhite or coturnix quail, ringneck pheasant, trout, sunfish, oysters. The quantity of pesticide (ppm in diet or environment; mg/kg consumed) should be determined which produces acute or chronic poisoning or which shows measurable sublethal effects on growth or reproduction. Tissues (including gonads and eggs) should be analysed at each degree of exposure.

  13. Fatal poisonings in Oslo: a one-year observational study

    Heyerdahl Fridtjof

    2010-06-01

    Full Text Available Abstract Background Acute poisonings are common and are treated at different levels of the health care system. Since most fatal poisonings occur outside hospital, these must be included when studying characteristics of such deaths. The pattern of toxic agents differs between fatal and non-fatal poisonings. By including all poisoning episodes, cause-fatality rates can be calculated. Methods Fatal and non-fatal acute poisonings in subjects aged ≥16 years in Oslo (428 198 inhabitants were included consecutively in an observational multi-centre study including the ambulance services, the Oslo Emergency Ward (outpatient clinic, and hospitals, as well as medico-legal autopsies from 1st April 2003 to 31st March 2004. Characteristics of fatal poisonings were examined, and a comparison of toxic agents was made between fatal and non-fatal acute poisoning. Results In Oslo, during the one-year period studied, 103 subjects aged ≥16 years died of acute poisoning. The annual mortality rate was 24 per 100 000. The male-female ratio was 2:1, and the mean age was 44 years (range 19-86 years. In 92 cases (89%, death occurred outside hospital. The main toxic agents were opiates or opioids (65% of cases, followed by ethanol (9%, tricyclic anti-depressants (TCAs (4%, benzodiazepines (4%, and zopiclone (4%. Seventy-one (69% were evaluated as accidental deaths and 32 (31% as suicides. In 70% of all cases, and in 34% of suicides, the deceased was classified as drug or alcohol dependent. When compared with the 2981 non-fatal acute poisonings registered during the study period, the case fatality rate was 3% (95% C.I., 0.03-0.04. Methanol, TCAs, and antihistamines had the highest case fatality rates; 33% (95% C.I., 0.008-0.91, 14% (95% C.I., 0.04-0.33, and 10% (95% C.I., 0.02-0.27, respectively. Conclusions Three per cent of all acute poisonings were fatal, and nine out of ten deaths by acute poisonings occurred outside hospital. Two-thirds were evaluated as accidental

  15. DDE poisoning in an adult bald eagle

    Garcelon, D.K.; Thomas, N.J.

    1997-01-01

    A 12-year-old female bald eagle (Haliaeetus leucocephalus) was found in May 1993 on Santa Catalina Island, California (USA), in a debilitated condition, exhibiting ataxia and tremors; it died within hours. On necropsy, the bird was emaciated but had no evidence of disease or physical injury. Chemical analyses were negative for organophosphorus pesticides and lead poisoning. High concentrations of DDE (wet weight basis) were found in the brain (212 ppm), liver (838 ppm), and serum (53 ppm). Mobilization of DDE, from depleted fat deposits, probably resulted in the lethal concentration in the eagle's brain.

  5. PROFILE OF POISONING CASES IN A TERTIARY CARE HOSPITAL, TAMILNADU

    Karikalan

    2014-10-01

    Full Text Available BACKGROUND AND OBJECTIVES: Poisoning is an important public health problem causing significant morbidity and mortality throughout the world. Knowledge of general pattern of poisoning in a particular region will help in early diagnosis and treatment of cases, thus decreasing the rate of mortality and morbidity. Information available in our locality with regard to acute poisoning is limited. The present study was carried out with the objective to investigate the pattern of acute poisoning cases in a tertiary care hospital in Coimbatore, Tamilnadu. MATERIALS AND METHODS: A retrospective analysis of all acute poisoning cases admitted to the emergency department of Karpagam Faculty of Medical Sciences and Research from April 2003 to March 2004 was done to study the pattern of poisoning. Data regarding age, sex, marital status, occupation, religion, locality, route of exposure, time elapsed after intake, circumstances of poisoning, name of poisonous substance, chemical type, duration of hospitalization and outcome were collected and analyzed. RESULTS: All reported cases were found to be suicidal poisoning. Majority of cases were in the age group of 11 – 20 years. Females (112 cases, 70% outnumbered males (48 cases, 30%. Students attempted to commit suicide much commoner than others followed by house wives and daily wage laborers. The commonest poison consumed was cow dung powder. The mortality rate was higher among those consumed rat killer poison (37.5%. CONCLUSION: This study adds information to the existing data which may help to develop prevention strategies. Health education to adolescents at school and college level about poisoning, regular counseling program for all high school children either by an in house trained faculty or a child psychologist and early detection of risk taking behavior in adolescents may to some extent prevent deliberate self-harm in teenagers. Ban on cow dung powder sales in grocery shops should be followed by district

  7. Intentional and unintentional poisoning in Pakistan: a pilot study using the Emergency Departments surveillance project

    2015-01-01

    Background Acute poisoning is one of the most common reasons for emergency department visits around the world. In Pakistan, the epidemiological data on poisoning is limited due to an under developed poison information surveillance system. We aim to describe the characteristics associated with intentional and unintentional poisoning in Pakistan presenting to emergency departments. Methods The data was extracted from the Pakistan National Emergency Department Surveillance (Pak-NEDS) which was an active surveillance conducted between November 2010 and March 2011. All patients, regardless of age, who presented with poisoning to any of Pakistan's seven major tertiary care centers' emergency departments, were included. Information about patient demographics, type of poisoning agent, reason for poisoning and outcomes were collected using a standard questionnaire. Results Acute poisoning contributed to 1.2% (n = 233) of patients with intentional and unintentional injuries presenting to EDs of participating centers. Of these, 68% were male, 54% were aged 19 to 44 and 19% were children and adolescents (drug/medicine (27%), alcohol (16.7%) and food/plant (6%). In half of all patients the poisoning was intentional. A total of 11.6% of the patients were admitted and 6.6% died. Conclusion Poisoning causes more morbidity and mortality in young adults in Pakistan compared to other age groups, half of which is intentional. Improving mental health, regulatory control for hazardous chemicals and better access to care through poison information centers and emergency departments will potentially help control the problem.

  8. Organophosphorus and carbamate insecticide poisoning.

    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.

    2008-01-01

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

  16. Arsenic – Poison or medicine?

    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

  17. VIGILANCE POISON: Illegal poisoning and lead intoxication are the main factors affecting avian scavenger survival in the Pyrenees (France).

    Berny, Philippe; Vilagines, Lydia; Cugnasse, Jean-Marc; Mastain, Olivier; Chollet, Jean-Yves; Joncour, Guy; Razin, Martine

    2015-08-01

    A specific surveillance program has been set up to monitor avian scavenger populations in the French Pyrenean Mountains, hosting a high proportion of the French populations. The two main purposes of the study were to identify all causes of death and to investigate poisoning cases. All 170 birds found dead during the 7-year program were submitted to full necropsy, X-Ray, parasitological investigations and consistent analytical toxicology screenings (Cholinesterase inhibitors, anticoagulant rodenticides, organochlorine insecticides, Pb, Cd). Over the study period, 8 Bearded Vultures, 120 Griffon Vultures, 8 Egyptian Vultures and 34 Red kites were eventually collected. Mortality events were often multifactorial, but poisoning was by far the most common cause of death (24.1%), followed by trauma/fall (12%), bacterial diseases and starvation (8%) and electrocution (6%). Illicit use of banned pesticides was identified as a common cause of poisoning (53% of all poisoning cases) and lead poisoning was also identified as a significant toxicant issue (17% of all poisoning cases). Lead isotopic signature could be associated primarily with ammunition. Last, a positive association between trauma and lead contamination was detected, indicating that lead could be a significant contributor to different causes of death. These results urge for severe restrictions on the use of lead ammunition to prevent scavengers from detrimental exposure. PMID:25913360

    Full Text Available Foram revisados casos de intoxicação por samambaia (Pteridium aquilinum em bovinos de 10 pequenas propriedades rurais de sete municípios da Região Central do Rio Grande do Sul. O estudo abrangeu 6.256 necrospias de bovinos realizadas num período de 43 anos e incluiu 15 necropsias de bovinos que morreram em conseqüência da intoxicação aguda por samambaia. As taxas de morbidade e mortalidade foram 17,9% e a letalidade era virtualmente de 100%. Em 40% das propriedades a doença ocorreu em pequenos surtos afetando vários bovinos; em 60% das propriedades apenas um bovino era afetado. Os principais sinais clínicos incluíam febre (40-42ºC, apatia, salivação e hemorragias, principalmente pelas gengivas, pela cavidade nasal e pelo trato gastrintestinal. Múltiplas petéquias eram observadas nas mucosas e na pele. Ocasionalmente observou-se hematúria e sangue no leite. A doença era invariavelmente fatal após um curso clínico de dois dias. Alterações hematológicas consistiam de leucopenia por neutropenia, anemia normocítica normocrômica e trombocitopenia arregenerativa. Os achados de necropsia incluíam hemorragias de intensidade variável em vários órgãos e infartos no fígado. Tanto as hemorragias quanto os infartos foram confirmados histologicamente; agregados de bacilos e vasos trombosados foram observados em associação com os infartos. Aplasia da medula óssea era um achado consistente nos quatro casos em que esse órgão foi examinado.Cases of acute poisoning by bracken fern (Pteridium aquilinum in cattle from 10 small farms of seven municipalities of the Central Region of Rio Grande do Sul State, Brazil, were reviewed.
