    The paper discussed a case of acute zinc intoxication in a 48-year old welder, after four days of cutting zinc-plated pipes with an oxy-acetylene torch, in poorly ventilated places. The zinc fever has been diagnosed on the basis of the symptoms and confirmed by laboratory findings: high zinc blood and erythrocyte concentration and increased urinary excretion of zinc. One year the intoxication the manifestations of the psycho-organic syndrome with predilection to pseudoneurotic reactions were still present. The non-standard factor in this case is the very short time of exposure to zinc oxide and the occurrence of chronic encephalopathy is also singular.

    The acutely poisoned patient remains a common problem facing doctors working in acute medicine in the United Kingdom and worldwide. This review examines the initial management of the acutely poisoned patient. Aspects of general management are reviewed including immediate interventions, investigations, gastrointestinal decontamination techniques, use of antidotes, methods to increase poison elimination, and psychological assessment. More common and serious poisonings caused by paracetamol, salicylates, opioids, tricyclic antidepressants, selective serotonin reuptake inhibitors, benzodiazepines, non-steroidal anti-inflammatory drugs, and cocaine are discussed in detail. Specific aspects of common paediatric poisonings are reviewed. PMID:15811881

    Intoxication by pyrimethamine is rare compare to these of patients who ingest a massive dose of amino-4-quinoleine. Clinic manifestations can be delayed and they are specially based on haematologic disorder as shown by literature data. Others organs can be concerned. The authors would like to present the case of a patient with a severe pancytopenia accompanied with: ocular blow like hyperhaemia of conjunctiva then iris siderosis. skin attack as Gũnther's disease. Etiologic treatment by folinic acid is the only deduction. Recovery is complete.

    In acute poisoning the maintenance or reconstitution of vital functions is the first and most critical action. All subsequent therapies and the prognosis depend on the identification of the causative agent and on information about substance-specific toxicity. Despite incomplete evidence the concept of harm reduction by decreased absorption of the toxicants and by shortening the course of illness is consistent with toxicokinetic-dynamic principles and is therefore still used by clinical toxicologists. All these treatment options have to be seen within the context of the prognosis and the time course of an individual case of poisoning. Treatment options of gastrointestinal decontamination are (in decreasing order of importance) single-dose activated charcoal, whole bowel irritation, and gastric lavage. Induced emesis by ipecac syrup is not practiced anymore. Enhanced elimination techniques are multiple-dose activated charcoal, urine alkalinization, and extracorporeal techniques such as hemodialysis and hemoperfusion. Enhanced elimination is only beneficial in toxicants with long half-life. Antidotes are directed against specific agents and therefore may be used only in a limited number of cases. The procurement of specific antidotes, often hardly available and not approved, is facilitated if the supply is organized in a transparent and standardized manner.

    Dapsone (DDS-diamino diphenyl sulphone) is a sulfone antibiotic being used for a variety of clinical conditions. Poisoning in children by DDS is rarely reported. Poisoning in acute cases will be frequently unrecognized due to relative lack of severe signs and symptoms. Methemoglobinemia is the major life-threatening situation associated with poisoning of DDS. Hence, any delay for medical attention can lead to increased rate of mortality. In this case, we describe acute DDS poisoning in a 3-year-old child and the successful management using intravenous methylene blue. PMID:26488029

    A case of carbon monoxide poisoning is presented with unusual complications; some of which have not been reported previously. A 48-years-old Asian male presented to the emergency department with dyspnoea, altered state of consciousness and pale discolouration of skin after being locked inside a factory room with burning coal. Patient was in acute respiratory distress. Arterial blood gas analysis showed respiratory acidosis with hypoxaemia. On 3rd day, patient developed dark coloured urine and right upper limb ischaemia. Acute renal failure was diagnosed. A doppler ultrasound showed stenosis of radial and ulnar arteries. 0n 8th day, patient regained consciousness and complained of loss of vision. An MRI of the brain revealed bilateral occipital venous infarcts. Cortical venous infarcts and arterial stenosis are rare complications of acute carbon monoxide poisoning.

    Acute organophosphorus poisoning continues to be a detrimental problem and a potential cause of mortality especially in developing countries. Inhibition of acetylcholinesterase enzyme is the main mechanism of toxicity of such pesticides and measurement of acetylcholinesterase activity is the commonly used laboratory diagnosis approved for the purpose. It is now proved beyond any doubt that early intervention is beneficial for cases of acute organophosphorus poisoning and, therefore, considerable current interest has been generated for development of point of care testing tool for screening of the same. However, to the best of our knowledge so far the matter is not reviewed from the view of point of care testing tool development. In this paper, this subject is reviewed highlighting the methodological aspects and point of care testing tool development in the context of organophosphorus poisoning.

    Paraquat concentration-time data have been used to predict the clinical outcome following ingestion. However, these studies have included only small populations, although paraquat poisoning has a very high mortality rate. The purpose of this study was to develop a simple and reliable model to predict survival according to the time interval post-ingestion in patients with acute paraquat poisoning. Data were retrospectively collected for patients who were admitted with paraquat poisoning to Soonchunhyang University Choenan Hospital between January 2005 and December 2012. Plasma paraquat levels were measured using high-performance liquid chromatography. To validate the model we developed, we used external data from 788 subjects admitted to the Presbyterian Medical Center, Jeonju, Korea, between January 2007 and December 2012. Two thousand one hundred thirty six patients were included in this study. The overall survival rate was 44% (939/2136). The probability of survival for any specified time and concentration could be predicted as (exp(logit))/(1+exp(logit)), where logit = 1.3544+[-3.4688 × log10(plasma paraquat μg/M[Formula: see text])]+[-2.3169 × log10(hours since ingestion)]. The external validation study showed that our model was highly accurate for the prediction of survival (C statics 0.964; 95% CI [0.952-0.975]). We have developed a model that is effective for predicting survival after paraquat intoxication.

    Chemical substances have an important threat due to extensive use in medicine, agriculture, industry and environment. In this retrospective study, etiological and demographic characteristics of acute poisoning cases admitted to a hospital in Iran were investigated. We compared these data with those reported from other parts of the country and the international experiences to evaluate any difference if exists. 7 052 poisoned cases admitted to the hospital from April 2006 to March 2013, by data collected from the medical record in poison center section. According to our results there is a predominance of male patients and the majority of the poisoned patients were between 20-30 years old. Drug poisoning was the most common cause of poisonings. The most frequently involved drugs were benzodiazepines and antidepressants. The seasonal distribution of our study showed a peak in summer. To prevent acute poisonings, the social education about the risk assessment of central nervous system-acting drugs and reduction of the exposure period of people to pesticides are recommended. This study suggested a proper educational program for the public and primary care units. Our results provide useful information for preventive strategies.

    Objectives: Datura Stramonium (DS) is a common weed along roadsides, in cornfields and pastures and in waste areas. It belongs to the family Solanaceae and its toxic components are tropane belladonna alkaloids. It has been used voluntarily by teenagers for its hallucinogenic effect. The plant is named in Iran as Tatoore. Symptoms and signs of acute D. Stramonium poisoning usually are similar to anticholinergic syndrome. This study is done in order to clarify the status of this poisoning in our region. Materials and Methods: This study is a case series on all patients admitted to Imam Reza Hospital, Mashhad, Iran, with acute D. Stramonium poisoning between 2008 and 2011. We observed their symptoms, signs, routine laboratory test results and treatment used to control their symptoms. Results: There were 19 patients included in our study. Children were poisoned more commonly than teenagers and poisoning in adults was rare. All of the children ingested the plant accidentally. The most presenting symptom was irritability and the most common sign was sinus tachycardia. There was not any presentation of seizure or coma. Most of the symptoms were controlled by parenteral benzodiazepines and there were no need to use of cholinergic agents such as physostigmine. Conclusion: Our study showed most of D. Stramonium poisoned population in our region are children. We suggest decreasing accessibility to the plant in order to decrease the incidence of its poisoning. PMID:25050235

    Boric acid comes as colourless, odourless white powder and, if ingested, has potential fatal effects including metabolic acidosis, acute renal failure and shock. An 82-year-old male was brought to the emergency room 3 h after unintentional ingestion of a large amount of boric acid. Clinical course was monitored by collecting data at admittance, 12 h after admission, every 24 h for 5 days and again 1 week after admission. During the first 132 h, serum and urinary concentrations of boric acid were measured. Serum boric acid levels decreased from 1800 to 530 microg/ml after haemodialysis and from 530 to 30 microg/ml during the forced diuresis period. During dialysis, boric acid clearance averaged 235 ml/min with an extraction ratio of 70%. The overall patient's condition steadily improved over 84 h after admission. In conclusion, early treatment with forced diuresis and haemodialysis may be considered for boric acid poisoning, even if signs of renal dysfunction are not apparent, to prevent severe renal damage and its complications.

    Aluminum phosphide poisoning is common in our region. It can cause severe metabolic acidosis and persistent hypotension, which lead to cardiogenic shock and subsequently mortality. Oliguric or anuric acute kidney injury is seen in almost all patients with aluminum phosphide poisoning. Renal replacement therapies are recommended in these patients to improve metabolic acidosis and increase the rate of survival. We report 2 cases of severe acute aluminum phosphide poisoning treated successfully with peritoneal dialysis.

    This study describes the epidemiology of acute lead poisoning in western Canadian cattle over the 16-year period of 1998 to 2013 and reports background bovine tissue lead concentrations. Case records from Prairie Diagnostic Services, Western College of Veterinary Medicine, identified 525 cases of acute lead toxicity over the investigational period. Poisonings were influenced by year (P < 0.0001) and month (P < 0.0001). Submissions were highest in 2009 (15.6%), 2001 (11.2%), and 2006 (9.9%). Most cases were observed during May, June, and July (62.3%). Cattle 6 months of age and younger were frequently poisoned (53.5%; P < 0.0001). Beef breeds were predominantly poisoned. Mean toxic lead concentrations (mg/kg wet weight) in the blood, liver, and kidney were 1.30 ± 1.70 (n = 301), 33.5 ± 80.5 (n = 172), and 56.3 ± 39.7 (n = 61). Mean normal lead concentrations in the blood, liver, and kidney were 0.036 ± 0.003 mg/kg (n= 1081), 0.16 ± 0.63 mg/kg (n = 382), and 0.41 ± 0.62 mg/kg (n = 64).

    It is estimated that there are over 5,000 species of mushrooms worldwide. Some of them are edible and some are poisonous due to containing significant toxins. In more than 95% of mushroom toxicity cases, poisoning occurs as a result of misidentification of the mushroom by an amateur mushroom hunter. The severity of mushroom poisoning may vary, depending on the geographic location where the mushroom is grown, growth conditions, the amount of toxin delivered, and the genetic characteristics of the mushroom. Amanita phalloides is the most common and fatal cause of mushroom poisoning. This mushroom contains amanitins, which are powerful hepatotoxins that inhibit RNA polymerase II in liver. Mushroom poisoning is a relatively rare cause of acute liver failure. A 63-year-old male patient was admitted to the emergency room with weakness, nausea, vomiting, and diarrhea. He reported ingesting several wild mushrooms about 36 hours earlier. In this article we report a case of lethal Amanita phalloides intoxication from stored mushrooms.

    Objective: Methadone poisoning is common in our society, mainly in drug addicts. One of its lethal complications is pulmonary edema. Therefore, we evaluated the prevalence of pulmonary edema in the deceased cases with methadone poisoning and its possible relationship with some medical variables. Methods: In this cross-sectional study which was done in 2014, we have investigated the deceased patients with methadone toxicity who underwent autopsy at Isfahan Forensic Medicine Department (Iran). All variables including age, gender, and autopsy findings were recorded and analyzed. Demographic characteristics and medical complications of the patients were compared between the patients with or without pulmonary edema in the autopsy findings. Findings: There were 64 cases who died with methadone poisoning during the 1-year study period. The average age of cases (±standard deviation) was 32.1 ± 10.29 years, among which 92.2% were male. Based on the autopsy findings, 64.1% were diagnosed with pulmonary edema. There was no statistically significant relationship between pulmonary edema and age, gender, history of addiction, and hepatic or cardiovascular complications. Conclusion: Pulmonary edema is a common finding in deceased methadone poisoning cases and must be considered and ruled out in patients with acute methadone toxicity. PMID:27843967

    Introduction: A variety of factors have influenced the significant incidence of morbidity and mortality of acute poisoning and the timely recognition and properly management of critically ill poisoned patients is a key component. The aim of this study is to reveal the reasons for ICU admission of acutely poisoned patients, the main factors influencing the course and outcome of patients in relation with clinical approaches applied, available resources and infrastructure of treatment. Materials and Methods: This is a retrospective study based on most reachable variables extracted from patients’ medical records and ED registers of patients admitted at the medical ICU of “Mother Teresa” University Hospital in Tirana over two (2012-2013) years. Demography, time of exposure, etiology and circumstances of poisonings, assessment and treatment, reasons for ICU admission, course and outcome were duly obtained. Results: The number of ICU treated patients was 118, consisting in 47.4% (56) males and 52.5% (62) females which represented 10.2% of poisoned patients admitted during this two-year-period in ED and 9.2% of other etiology ICU admitted patients. Mean was 42.6 years for males, and 38 years for females. About 55.9% were urban residents and 44% rural ones. The elapsed time from toxic exposure to treatment initiation had varied between 2-6 hours, 44% arrived in the hospital <4 hours. The toxic exposures were intentional in 87.2% of cases, with a male:female ratio was 0.8:1. Agrochemicals such as Aluminum phosphide and organophosphates were involved in 77.1% of cases. Cardiovascular collapse and respiratory failure were the main clinical syndromes encountered. Mechanical ventilation was required in 31.4% of patients. The length of ICU stay was 2.73 (0.96) days and the mortality was 54.2%. Conclusion: This study evidenced that highly lethal toxicants used in poisoning acts such as agrochemicals, high rate of suicide, notwithstanding the infrastructure and resources

    2013-03-01

    We describe a case of an acute lethal poisoning with hydrocarbons resulting from massive accidental inhalation of gasoline vapors. The victim, a 50-year-old man was found unconscious inside a control room for the transport of unleaded fuel. Complete autopsy was performed and showed evidence of congestion and edema of the lungs. Toxicological investigation was therefore fundamental to confirm exposure to fumes of gasoline. Both venous and arterial blood showed high values of volatiles in particular for benzene (39.0 and 30.4 μg/mL, respectively), toluene (23.7 and 20.4 μg/mL), and xylene isomers (29.8 and 19.3 μg/mL). The relatively low values found in the lungs are consistent with the fact that the subject, during the rescue, underwent orotracheal intubation followed by resuscitation techniques, while the low concentrations for all substances found in urine and kidneys could point to a death that occurred in a very short time after first contact with the fumes of gasoline.

    The aim of this study is to report ophthalmic findings of acute mercury poisoning in 48 adults referred to emergency department. Full ophthalmologic examination including the best corrected visual acuity, external eye examination, reaction to light, a slit-lamp examination, funduscopy, intraocular pressure measurements, and visual field (VF) and color vision (CV) tests were performed at the presentation and repeated after 6 months. The parametric values of VF test, the mean deviation (MD), and pattern standard deviation (PSD) were recorded in order to compare patients and the 30 healthy controls. The mean parameter of color confusion index in patients was found to be statistically different than controls (p < 0.01). The MD and PSD in patients were different from controls statistically significant (p < 0.01 and p < 0.01, respectively). There was no correlation between the ocular findings and the urine and blood mercury levels. Methyl mercury, held in the school laboratory for experimental purpose, may be a source of poisoning. In this case series, we showed that acute exposure to mercury had hazardous effect on the visual system, especially CV and VF. We propose that emphasizing the public education on the potential hazards of mercury is crucial for preventive community health.

    This paper describes the accidental poisoning of five workers by cadmium fume. The men were dismantling a frame of girders in a confined space by cutting bolts with an oxyacetylene burner. They were unaware at the time that the bolts were cadmium-plated or that this presented a serious industrial hazard. The paper sets out to give an appreciation of acute cadmium poisoning, the characteristics and uses of cadmium, and a review of the literature. The clinical picture of these cases is described, with the pathology of the fatal case which showed severe pulmonary oedema, alveolar metaplasia of the lung, and bilateral cortical necrosis of the kidneys. The lungs contained 0·25 g. cadmium oxide (CdO) per 100 g. wet specimen. An attempted estimation of the fatal dose of CdO fume is made. From the post-mortem findings, using an assumption that 11% of inhaled CdO will be retained in the lungs, approximately 51·7 mg. CdO fume must have been inhaled by the fatal case. As he worked for five hours with a probable ventilatory rate of 20 l./min. the concentration of CdO in the air breathed would be of the order of 8·6 mg./m.3. An estimation of the dose from a study of the working conditions proved unsatisfactory due to certain variables listed in the text. Images PMID:5928153

    Paraquat is commonly used herbicide by farmers in North West Rajasthan. Despite its easy availability, poisoning of its not common. Fatal dose of paraquat is so small that >10 ml poison can damage lungs permanently. Diagnosis is often difficult without proper history, absence of specific clinical feature and lack of diagnostic test. Inhalation exposures represent one of the most important routes of poisoning. We are reporting a case of inhaled paraquat poisoning with complication of irreversible acute kidney, liver and lung injury. PMID:27042505

    Zinc vapour poisoning by inhalation in the form of zinc fever is more frequent than oral zinc product poisoning, the product used in therapy. The main aim of the study was the evaluation of clinical manifestation present after Zincteral ingestion as well as attempt to find the relationship between the presence and aggravation of the clinical manifestation and zinc level in the blood. The course of acute clinical suicidal poisoning by ingestion of Zincteral 50 tablets (10.0 g) and 100 tablets (20.0 g) is presented. The clinical picture revealed the following symptoms and signs: tachycardia, changes of arterial BP, vascular shock; dyspeptic nausea, vomiting cramps in abdominal region, diarrhoea. Damage of the parenchymatous organs, mainly liver was evident. In pregnant woman (9-week-pregnancy) on the 12-th day of her stay in the Clinic complete miscarriage took place accompanied by haemorrhage from reproductive organs. The kind and exacerbation of the clinical manifestations in relation to the zinc level in body fluid were analysed.

  3. Chronic Neuropsychological Sequelae of Cholinesterase Inhibitors in the Absence of Structural Brain Damage: Two Cases of Acute Poisoning

    Roldán-Tapia, Lola; Leyva, Antonia; Laynez, Francisco; Santed, Fernando Sánchez

    2005-01-01

    Here we describe two cases of carbamate poisoning. Patients AMF and PVM were accidentally poisoned by cholinesterase inhibitors. The medical diagnosis in both cases was overcholinergic syndrome, as demonstrated by exposure to cholinesterase inhibitors. The widespread use of cholinesterase inhibitors, especially as pesticides, produces a great number of human poisoning events annually. The main known neurotoxic effect of these substances is cholinesterase inhibition, which causes cholinergic overstimulation. Once AMF and PVM had recovered from acute intoxication, they were subjected to extensive neuropsychological evaluation 3 and 12 months after the poisoning event. These assessments point to a cognitive deficit in attention, memory, perceptual, and motor domains 3 months after intoxication. One year later these sequelae remained, even though the brain magnetic resonance imaging (MRI) and computed tomography (CT) scans were interpreted as being within normal limits. We present these cases as examples of neuropsychological profiles of long-term sequelae related to acute poisoning by cholinesterase inhibitor pesticides and show the usefulness of neuropsychological assessment in detecting central nervous system dysfunction in the absence of biochemical or structural markers.

    A coupled column system was developed for the simultaneous determination of both rodenticides fluoroacetamide and tetramine in this paper by gas chromatography/mass spectrometry (GC/MS). A short length of strong polar column (1.5 m of Innowax) was coupled to the top of a 30 m of DB-5 ms with a quartz capillary column connector. Peak width at half height (W(h)) was used to evaluate the band broadening of the coupled column system. The length of the short couple column and oven temperature program were discussed according to W(h). The precisions of the coupled column were analyzed with peak area and retention time. Good linear correlations were found for both rodenticides. Typical samples were discussed for each rodenticide and some poisoning cases were presented.

  6. A Case of Mushroom Poisoning with Russula subnigricans: Development of Rhabdomyolysis, Acute Kidney Injury, Cardiogenic Shock, and Death

    2016-01-01

    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) poisoning is still complicated by a high mortality and morbidity rate. Diagnosis can be obvious but is most of time difficult and sometimes remained unknown. It is usually based on clinical signs and must be confirmed by assessment of CO level in room air or in patient's expired breathing or blood and detection of a source. Mild neurological sequelae are very common. Normobaric oxygen is the first line treatment. Comatose and pregnant patients must undergo hyperbaric oxygen. All CO poisoning has to be declared to sanitary authority, which will in turn conduct a technical inspection to remove the source. The patient must be informed that he is at risk of new poisoning and of neurological complications. Progress in prevention and research in therapeutics are needed in order to reduce CO related morbidity.

    Acute organophosphate poisoning (OP) shows several severe clinical symptoms due to its strong blocking effect on cholinesterase. Acute pancreatitis is one of the complications associated with acute OP, but this association still may not be widely recognized. We report here the case of a 73-year-old man who had repeated abdominal pain during and after the treatment of acute OP. Hyperamylasemia and a 7-cm pseudocyst in the pancreatic tail were noted on investigations. We diagnosed pancreatic pseudocyst that likely was secondary to an episode of acute pancreatitis following acute OP. He was initially treated with a long-term intravenous hyperalimentation, protease inhibitors and octerotide, but eventually required surgical intervention, a cystgastrostomy. Acute pancreatitis and hyperamylasemia are known to be possible complications of acute OP. It is necessary to examine and assess pancreatic damage in patients with acute OP.

    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

    Phostoxin is a mixture of aluminium phosphide and ammonium carbonate. When exposed to water, it releases phosphorus hydrogen (PH3), a highly-poisonous gas. In Morocco, death rate from suicide due to self-administration of phostoxin pills is high. Clinical signs include abrupt digestive and nervous disorders. Pulmonary oedema or cardiogenic shock dominate early prognosis. Liver and renal damage is secondary. Prevention requires both legal constraints and regulation of sales.

    The authors reviewed the clinical manifestations, complications, and the prognosis affected by Lilly Cyanide Antidote in 21 victims of acute cyanide poisoning over a 10-year period. The clinical signs and symptoms in cyanide poisoning are variable. Among 21 cases, loss of consciousness (15), metabolic acidosis (14), and cardiopulmonary failure (9) were the three leading manifestations of cyanide intoxication. Anoxic encephalopathy (6) was not uncommon in the severely intoxicated victims. Diabetes insipidus (1) or clinical signs and symptoms mimicking diabetes insipidus (3) may be an ominous sign to encephalopathy victims. The major cause of fatal cyanide poisoning is the intentional ingestion of cyanide compounds as part of a suicide attempt. Decrease of arteriovenous difference of O2 partial pressure may be a clue for the suspicion of cyanide intoxication. Although the authors cannot show a statistically significant difference (P = .47) for the Lilly cyanide antidote kit in terms of improving the survival rate for victims of cyanide poisoning, the antidote kit was always mandatory in our study in the cases of severely intoxicated victims who survived. Early diagnosis, prompt, intensive therapy with antidote, and supportive care are still the golden rules for the treatment of acute cyanide poisoning, whether in the ED or on the scene.

    Lead colic is a rare cause of abdominal pain. The diagnosis of lead poisoning is most often mentioned in at risk populations (children, psychotic). We report the case of a 2 year old child that was presented for acute abdomen. Abdominal plain radiograph showed multiple intra-colonic metallic particles and suggested lead poisoning diagnosis. Anamnesis found a notion of pica and consumption of peeling paint. Elevated blood lead levels (BLL) confirmed the diagnosis. The lead poisoning is a public health problem especially in children, but its manifestation by a lead colic is rare and could simulate an acute abdomen table.

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

    Barium is a heavy divalent alkaline earth metal that has been known as a muscle poison. Barium can cause human toxicity, which may lead to significant hypokalemia and have serious consequences. This paper reports a case of unprecedented barium intoxication in which the patient, who suffered from depression, swallowed at least 3.0 g barium chloride to commit suicide. On admission, the patient presented with nausea, vomiting, stomach burning feeling, dizziness, and weakness. Emergency biochemical testing showed that the patient was suffering from severe hypokalemia (K+ 1.7 mmol/L). His electrocardiogram (ECG) prompted atrioventricular blocking, ventricular tachycardia, prolongation of PR interval, ST segment depression with U waves, and T wave inversion. Intravenous potassium supplements were given immediately to correct hypokalemia and regular monitoring of vital signs and fluid balance was arranged. After all-out rescue of our hospital personnel, the condition of the patient is currently stable and he is gradually recovering. This case exemplifies the weaknesses of the management of toxic substances and the lack of mental health education for young people. We hope to get more attention for the supervision of toxic substances and the healthy development of young people. PMID:27840643

    GlySH-surfactant herbicide (GlySH), one of the most commonly used herbicides worldwide, has been considered as minimally toxic to humans. However, clinical toxicologists occasionally encounter cases of severe systemic toxicity. The US Environmental Protection Agency (EPA) states that ‘GlySH’ is of relatively low oral and acute dermal toxicity. It does not have anticholinesterase effect and no organophosphate-like central nervous system (CNS) effects. The clinical features range from skin and throat irritation to hypotension and death. Severe GlySH-surfactant poisoning is manifested by gastroenteritis, respiratory disturbances, altered mental status, hypotension refractory to the treatment, renal failure, and shock.[1] GlySH intoxication has a case fatality rate 3.2–29.3%. Pulmonary toxicity and renal toxicity seem to be responsible for mortality. Metabolic acidosis, abnormal chest X-ray, arrhythmias, and elevated serum creatinine levels are useful prognostic factors for predicting GlySH mortality.[2] There is no antidote and the mainstay of treatment for systemic toxicity is decontamination and aggressive supportive therapy. We report a case of acute pulmonary edema, which is a rare but severe manifestation of oral GlySH poisoning, where patient survived with aggressive supportive therapy. PMID:25948977

    A cross-sectional study was conducted to evaluate the electrocardiographic changes in 107 patients of acute organophosphorus poisoning admitted at casuality ward of MGM Medical College, Kisanganj from June 2007 to June 2010. Electrocardiographic changes were recorded before the administration of atropine. Prolonged Q-Tc interval was the commonest ECG abnormality, found in 67 patients (62.6%), followed by sinus tachycardia in 36 patients (33.6%). Sinus bradycardia was found in 33 patients (30.8%). Elevation of ST segment was seen in 27 patients (25.2%). T wave inversion was seen in 21 patients (19.6%). First-degree heart block (P-R interval >0.20 seconds) occurred in 9 cases (8.4%). Atrial fibrillation was seen in 5 patients (4.6%). Ventricular tachycardia was seen in 6 cases (5.6%) and ventricular premature complexes in 3 patients (2.8%). Of these 6 cases of ventricular tachycardia 1 responded to intravenous lignocaine, and the other 5 developed ventricular fibrillation leading to death despite other resuscitative measures. All the electrocardiographical abnormalities returned to normal before the patients were discharged. Seventeen patients died. The cause of death was ventricular fibrillation in 5 patients and non-cardiogenic pulmonary oedema in others. In conclusion it can be said that ECG should be carefully recorded and analysed in all patients of acute organophosphorus poisoning, and depending upon these changes and other clinical and biochemical parameters, the patients should immediately be shifted to well equipped ICU for better care which will reduce the mortality rate caused by these highly lethal poisons.

    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

    We present a case of severe acute nicotine poisoning in an 8 year old boy with moderate eczema after topical application of a traditional remedy from a book published in Bangladesh. Symptoms consistent with nicotine poisoning developed within 30 minutes of application of the remedy. The child subsequently improved with supportive care and was discharged after five days with no neurological sequelae. Diagnosis of nicotine poisoning was not initially made due to difficulty in obtaining an accurate history via an interpreter from the parents who did not speak English. Samples taken 12 hours after application of the remedy showed a serum nicotine of 89 µg/l, serum cotinine of 1430 µg/l, urine nicotine of 1120 µg/l, and a urine cotinine of 6960 µg/l confirming acute nicotine poisoning.

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

    A case of triphenyltin acetate (TPTA) poisoning is described. The patient, who had been exposed mainly to cutaneous absorption, showed acute stages of an urticarial eruption, signs of hepatic injury, slight glucose intolerance, and electroencephalographic abnormalities. Concomitant with the highest concentrations of tin in plasma and the peak of tin excretion in urine, neutrophils did not show the normal increase in actin polymerisation after stimulation with a chemotactic peptide (100 nM fMLP). The peak of urinary excretion of tin occurred between the fifth and the sixth day after poisoning; subsequently, the rate of excretion became slow, suggesting biphasic kinetics with the possibility of a cumulative trend.

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

    Background. Acute poisoning represents one of the most common medical emergencies in childhood. In view of paucity of literature on accidental poisoning among children in Egypt, this study was designed to describe the pattern of childhood poisoning in Zagazig University Hospitals. Patients and Methods. This retrospective study included 300 children up to 12 years with acute poisoning admitted to the Pediatric Department and Poisoning Treatment Unit, Zagazig University Hospitals, from January 2011 to August 2012. Complete epidemiological and clinical data were recorded and analyzed. Results. Three hundred of poisoned children were enrolled in this study. Children from 1 to 6 years were more liable to poisoning (81%). More boys than girls were poisoned at all age groups. The majority of all cases (99%) were due to accidental poisoning. Overall, 32% of the poisoned cases were living in Zagazig city while 68% were living in the rural areas. The presenting symptoms were classic in 60% of the cases. Pesticides, therapeutic drugs, and cleaning and disinfectant agents were the most frequent poisoning agents (28.7%, 22.7%, and 17.0%, resp.). In 86.0% of cases, observation with or without supportive measures together with decontamination and specific antidote therapy whenever needed was sufficient. Conclusion. Most of the poisonings were due to accidental ingestions by infants and young children. Pesticides and medications were the most commonly involved agents. PMID:27351009

    Acute poisonings during pregnancy pose a particular challenge to health care providers because of the potential for an immediate life threat or possible life-long implications for both the mother and fetus, including teratogenicity of the poison or its antidote. We describe recent consequential exposures among pregnant women in the USA. We identified all poisoning cases involving pregnant women that were catalogued by the medical toxicology services across the 37 sites of the Toxicology Investigators Consortium (ToxIC) Registry of the American College of Medical Toxicology between January 2010 and December 2012. Of 17,529 exposure cases reported in the ToxIC Registry, 103 (0.6 %) involved pregnant women, 80 % of whom were symptomatic and about a quarter displayed a specific toxidrome. The majority of cases (n = 53; 51.5 %) involved intentional exposures, most commonly to pharmaceutical agents, followed by unintentional pharmaceutical exposures (10 %) and withdrawal syndromes (9 %). Non-opioid analgesics were the most common class of agents encountered (31 %), followed by sedative-hypnotics/muscle relaxants (18 %), opioids (17 %), anti-convulsants (10 %), and anti-depressants (10 %). Over a third of cases involved exposure to multiple substances, and 32 % involved exposure to more than one drug class. The most commonly administered antidotes were N-acetylcysteine (23 %), sodium bicarbonate (10 %), flumazenil (4 %), and physostigmine (4 %). About half of acute poisoning cases among pregnant women presenting for emergency care involved intentional exposures, mostly with over-the-counter analgesics and psychoactive medications. Clinicians should be cognizant of the unique circumstances, maternal and fetal risks, and management principles of the acutely poisoned pregnant woman.

    Parkinsonism is a rare complication in patients with organophosphate poisoning. To date there have been two cases of transient parkinsonism after acute and severe cholinergic crisis, both of which were successfully treated using amantadine, an anti-parkinsonism drug. We report on an 81-year-old woman who was admitted for the treatment of acute severe organophosphate poisoning. Although acute cholinergic crisis was treated successfully with large doses of atropine and 2-pyridine aldoxime methiodide (PAM), extrapyramidal manifestations were noticed on hospital day 6. The neurological symptoms worsened, and the diagnosis of parkinsonism was made by a neurologist on hospital day 9. Immediately, biperiden (5mg), an anti-parkinsonism drug, was administered intravenously, and her symptoms markedly improved. From the following day, biperiden (5 mg/day) was given intramuscularly for eight days. Subsequently, neurological symptoms did not relapse, and no drugs were required. Our patient is the third case of parkinsonism developing after an acute severe cholinergic crisis and the first case successfully treated with biperiden. Patients should be carefully observed for the presence of neurological signs in this kind of poisoning. If present, an anti-parkinsonism drug should be considered.

    The current study reported the case of a 35-year-old male that presented with antifreeze poisoning. The clinical manifestations, laboratory investigations and treatments were analyzed, and the obtained results were compared with those in previous reports. Subsequent to consuming antifreeze, the patient mainly presented nausea and agitation, without disturbance of consciousness. Laboratory investigations indicated severe metabolic acidosis, renal dysfunction and hyperkalemia. The patient underwent hemodialysis and his condition was significantly improved on the day of admission. Renal function gradually deteriorated, but was eventually improved due to treatment, including hemodialysis, mannitol for catharsis, furosemide for diuresis, Xuebijing for the removal of blood stasis and detoxication, and reduced glutathione for the protection of major organs. The patient was discharged 1 month after hospital admission. In conclusion, the significance and clinical manifestations of antifreeze poisoning should be identified in clinical practice, and active hemodialysis should be provided. The aim of the current study was to summarize the clinical manifestations and treatments of patients with antifreeze poisoning, and to advance the recognition of antifreeze poisoning. PMID:28352354

    The aim of this study was to investigate effectiveness of the poisoning severity score (PSS), Glasgow coma scale (GCS), and corrected QT (QTc) interval in predicting outcomes in acute organophosphates (OP) poisoning. Over a period of 2 years, 62 patients with OP poisoning were admitted to emergency department (ED) of Erciyes University Medical School Hospital. The age, sex, cause of contact, compound involved, time elapsed between exposure and admission to the ED, duration of hospital stay, and cardiac manifestations at the time of presentation were recorded. GCS and poisoning severity score (PSS) was calculated for each patient. Electrocardiogram (ECG) analysis included the rate, rhythm, ST-T abnormalities, conduction defects, and measurement of PR and QT intervals. Sixty-two patients with OP poisoning presented to our ED from January 2007 to December 2008 from which 54 patients were included in the study. The mean age was 34.1 +/- 14.8 years. Of the cases, 53.7% were female. Twenty-six patients had a prolonged QTc interval. Mean PSS of men and women was 1.8 +/- 1.0. No statistically significant correlation was found between the PSS and QTc intervals of the cases. A significant correlation was determined between the GCS and PSS of grade 3 and grade 4 cases. GCS is a parameter that helps clinician to identify advanced grade OP poisoning patients in the initial assessment in the ED. However, ECG findings, such as prolonged QTc interval, are not effective in determination of short-term prognosis and show no relationship with PSS.

    In recent years, the number of cases of acute poisoning has increased in China, yet; currently, there is no detailed report published that addresses acute poisoning in the mainland of China. We collected biological samples from 466 cases of suspected acute poisoning at the hospitals in Shanghai, China, and examined them using spectroscopy, chromatography and chromatography/mass spectrometry. Of the 466 cases, 230 cases (100 men and 130 women) were positively confirmed as acute poisonings. There were 80 types of compounds identified in this study. Medications were the most frequent substances identified, and the other substances included pesticides, multiple compounds, volatile compounds, natural toxins, and others. The results of this study indicate a need for strengthening the education about and management of the rational and safe use of drugs in Shanghai.

    Acute lead poisoning is not a common pathology seen in the pediatrician's office. Lead poisoning symptoms can be digestive or neurological, and they can be confused with other pathologies. That is the reason why it should be considered and, in case of doubt, complementary studies to confirm lead poisoning should be requested. This is the case of a nine-year-old child that comes to the office with a strong abdominal pain and vomiting, and after a close physical examination and a detailed anamnesis, a suspicious diagnosis of "acute" lead poisoning is obtained. Therefore, the infant is hospitalized, and after taking a venous sampling to confirm the lead level, a chelation therapy is performed under the toxicology expert's supervision.

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

  18. Gastrointestinal decontamination in the acutely poisoned patient

    PubMed Central

    2011-01-01

    Objective To define the role of gastrointestinal (GI) decontamination of the poisoned patient. Data Sources A computer-based PubMed/MEDLINE search of the literature on GI decontamination in the poisoned patient with cross referencing of sources. Study Selection and Data Extraction Clinical, animal and in vitro studies were reviewed for clinical relevance to GI decontamination of the poisoned patient. Data Synthesis The literature suggests that previously, widely used, aggressive approaches including the use of ipecac syrup, gastric lavage, and cathartics are now rarely recommended. Whole bowel irrigation is still often recommended for slow-release drugs, metals, and patients who "pack" or "stuff" foreign bodies filled with drugs of abuse, but with little quality data to support it. Activated charcoal (AC), single or multiple doses, was also a previous mainstay of GI decontamination, but the utility of AC is now recognized to be limited and more time dependent than previously practiced. These recommendations have resulted in several treatment guidelines that are mostly based on retrospective analysis, animal studies or small case series, and rarely based on randomized clinical trials. Conclusions The current literature supports limited use of GI decontamination of the poisoned patient. PMID:21992527

    The authors present a case of a college student who suffered acute gallium poisoning as a result of accidental exposure to gallium halide complexes. This is extremely rare and has never been reported in the literature. Acute symptoms after the incident, which initially presented as dermatitis and appeared relatively not life-threatening, rapidly progressed to dangerous episodes of tachycardia, tremors, dyspnea, vertigo, and unexpected black-outs. Had there been effective emergency medical care protocols, diagnostic testing, treatment and antidotes, the latent manifestations of irreversible cardiomyopathy may have been prevented. Given how quickly exposure led to morbidity, this article aims to raise an awareness of the toxic potential of gallium. This has particular relevance for workers involved in the production of semiconductors where there is a potential for accidental exposure to gallium by-products during device processing. It may also have implications for dentists who use gallium alloys to replace mercury containing amalgam. In the absence of threshold limit values and exposure limits for humans, as well as emergency medical guidelines for treatment of poisoning, the case calls on the National Institute for Occupational Safety and Health and the Occupational Safety and Health Administration to establish guidelines and medical management protocols specific for gallium.

    Organophosphate (OP) pesticide poisoning is a global health problem with over 250,000 deaths per year. OPs affect neuronal signaling through acetylcholine (Ach) neurotransmission via inhibition of acetylcholinesterase (AChE), leading to accumulation of Ach at the synaptic cleft and excessive stimulation at post-synaptic receptors. Mortality due to OP agents is attributed to respiratory dysfunction, including central apnea. Cholinergic circuits are integral to many aspects of the central control of respiration, however it is unclear which mechanisms predominate during acute OP intoxication. A more complete understanding of the cholinergic aspects of both respiratory control as well as neural modification of pulmonary function is needed to better understand OP-induced respiratory dysfunction. In this article, we review the physiologic mechanisms of acute OP exposure in the context of the known cholinergic contributions to the central control of respiration. We also discuss the potential central cholinergic contributions to the known peripheral physiologic effects of OP intoxication.

    Acute lead poisoning can present a difficult diagnostic dilemma, with symptoms that mimic those of hepatitis, nephritis, and encephalopathy. The authors report two cases in intravenous methamphetamine users who presented with abnormal liver function values, low hematocrit values, basophilic stippling of red blood cells, and elevated blood lead levels. Both patients excreted large amounts of lead in their urine after treatment with edetic acid, followed by resolution of their symptoms. Lead contamination was proved in one drug sample. Basophilic stippling of the red blood cells was the one key laboratory result that led to the definitive diagnosis in both cases.

    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.

    The methomyl is increasingly involved in suicidal and autolytic attempts. Intoxication with carbamate (CM) compounds is still a frequent cause for admission in the Emergency department of the medical assistance center (MAC) in Tunis, Tunisia. The aim of this study was to describe the demographics, clinical features and hospital course of patients presenting with CM intoxication to the ED of MAC in Tunis, Tunisia. This was a retrospective study about 52 cases of acute poisoning by methomyl, compiled in the MAC from 1st January, 2009 to December 31, 2012. Intoxications were all oral, mostly intentional (33 cases: 65%) and in young patients (29 years old). Females outnumbered males by almost 2:1. The most frequent symptom was hypotension (41 cases: 80%), followed by miosis (39 cases: 75%), rhabdomyolysis (29 cases: 55%), vomiting (18 cases: 43%), bronchorrhea (14 cases: 27%), diarrhea (11 cases: 21%) and fasciculations (8 cases: 17%). Treatments included gastric lavage in 16 patients (32%), assisted ventilation in 8 cases (17%) and atropine in 44 patients (85%). Seven patients died during hospitalization. Pesticide poisoning is a significant public health problem and some preventive measures must be strictly enforced to limit this kind of intoxication.

    Aluminum phosphide (AlP) as 3 g tablet is widely used in Iran to protect stored food grains from pests. Hyperglycemia following its ingestion has been already reported in the recent years but severe hypoglycemia is uncommon. Here, we report a 19 year old male who attempted suicide with one tablet of AlP and demonstrated severe hypoglycemia. Despite restoration of blood glucose concentration to normal, he failed to respond to supportive treatment and died. The possible mechanisms leading to severe hypoglycemia are discussed. Though severe hypoglycemia is rare following AlP poisoning, physicians managing such patients should be aware of it.

    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 < 0.001). When families were called for re-evaluation, it was determined that most of them had taken the necessary precautions after the poisoning incident (86.3%). This study determined that children with acute childhood 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.

    Objective Acute accidental poisoning in children is still an important public health problem. The epidemiological investigation specific for each country is necessary to determine the extent and characteristics of the problem. The aim of our study was to elucidate the current pattern of acute poisoning among children. Methods The present retrospective study describes the epidemiology of acute accidental poisoning in children (less than 10 years old) admitted to the Emergency Department of two teaching hospitals during a period of two years. Findings Three hundred and forty four children under 10 years old were admitted to emergency department of two teaching hospitals due to acute accidental poisoning. Drugs were the most common agents causing the poisoning (58.1%), followed by Hydrocarbons (13.1%), and opioids (9.3%). Common signs were neurological (42.6%) with lethargy being the most common (39.1%). 50.6% of cases were discharged from hospital within 6-12 hours, 91.6% of them without any complication. Conclusion Accidental poisonings are still a significant cause of morbidity among children in developing countries. Regarding the high prevalence of pharmaceutical drug poisoning and because lethargic was the most frequent neurological sign, comprehensive toxicology screen tests should be included as part of the routine evaluation of children presenting to an ED with an apparent life-threatening event.

    Paraquat is one of the most widely used herbicides in the world and is highly toxic to humans and animals. In this study, we developed a serum metabolomic method based on GC/MS to evaluate the effects of acute paraquat poisoning on rats. Pattern recognition analysis, including both principal component analysis and partial least squares-discriminate analysis revealed that acute paraquat poisoning induced metabolic perturbations. Compared with the control group, the level of octadecanoic acid, L-serine, L-threonine, L-valine, and glycerol in the acute paraquat poisoning group (36 mg/kg) increased, while the levels of hexadecanoic acid, D-galactose, and decanoic acid decreased. These findings provide an overview of systematic responses to paraquat exposure and metabolomic insight into the toxicological mechanism of paraquat. Our results indicate that metabolomic methods based on GC/MS may be useful to elucidate the mechanism of acute paraquat poisoning through the exploration of biomarkers.

    Colchicine poisoning is a rare event. Its outcome is, compared to other drug intoxications, often serious or even fatal. Intaxications with colchicine may occur by ingestion of tablets as well as by consumption of meadow saffron leaves (Colchicum autumnale) that are often mistakenly collected instead of the leaves of ramson herb (Allium ursinum). Colchicine poisoning typically shows three phases: initially gastrointestinal symptoms predominate, in the second phase multiorgan failure may occur possibly leading to death. In case the patient survives, the third phase of recovery follows during which the patients often present with hair loss. The fatal dose of acute colchicine poisoning is estimated at about 0.9 mg/kg. Since hemodialysis and hemoperfusion are not effective measures because of the high volume of distribution, an aggressive primary decontamination with gastric lavage and activated charcoal is required as early as possible. A promising new aspect in the treatment of heavy colchicine overdose is the immunotherapy with colchicine-specific fab-fragments. At present this treatment is still in an experimental stage and has been applied so far to one patient with beneficial effects. Unfortunately colchicine-specific antibodies are not yet commercially available.

    The aim of this retrospective epidemiological study was to investigate the demographical, etiological and clinical characteristics of acute drug poisonings in Iasi County, Romania. All patients were referred and admitted in the Toxicology Clinic of "Sf. Ioan" Emergency Clinic Hospital Iasi, Romania. Between 2003 and 2009, 811 cases of acute drug poisonings were recorded, counting for 28.43% from the total number of poisonings. The majority of these poisonings resulted in mild (51.94%) and medium (28.35%) clinical forms, while 19.71% were coma situations. In all, 63.51% of patients originated from urban areas, 39.94% were unemployed and the patients were predominantly women (66.46%). A high percentage (97.27%) were suicide attempts, using only one type of drug (65.88%) and the 21-30 years group (29.8%) records the highest incidence, for both women and men. The most frequently involved drugs were benzodiazepines 13.69%, anticonvulsive drugs 8.63%, barbiturates 8.51% and cardiovascular drugs 5.92%. Drugs combinations were recorded in 32.92% of cases and 1.2% were combinations between drugs and other substances. Mortality was the outcome in 0.3% of the total registered number of acute drug poisonings. This study underlines that in order to provide a proper management of these situations, a Regional Poison Information Center is absolutely necessary.

    Most poisonings from pesticides do not have a specific antidote, making decontamination the most important intervention. For maximal benefit to the patient, skin, eye, and gastric decontamination should be undertaken while specifics of the poisoning are being determined. As in most illnesses and injuries, the history of the poisoning is of great importance and will determine specific needs for decontamination and therapy, if any exist. Protection of health care workers during the decontamination process is important and frequently overlooked. Skin decontamination is primarily accomplished with large volumes of water, soap, and shampoo. Gastric decontamination by lavage is indicated if ingestion of the poisoning has occurred within 60 minutes of patient presentation. Activated charcoal, combined with a cathartic, is also indicated in most poisonings presenting within 60 minutes of ingestion. With large volume ingestion poisonings, activated charcoal may be used after 60 minutes, but little data exist to support this practice. Syrup of ipecac is no longer recommended for routine use. The cholinergic syndrome "all faucets on" characterizes poisoning by organophosphates and carbamates. Organochlorine insecticides (lindane and other treatments for scabies and lice) can produce seizures with excessive use or use on large areas of nonintact skin. Non-dipyridyl herbicides, biocides (including pyrethrins, pyrethroids, and Bacillus thuringiensis) rarely produce anything other than mild skin, eye, and/or gastrointestinal irritation on topical exposure or ingestion.

    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 (DIC). Renal biopsy showed acute tubular necrosis. Later, the consumed substance was proven to be mercuric chloride. His renal failure improved over time, and his creatinine normalized after 2 months. PMID:27194836

    Cyanide poisoning presents in many forms. Industrial intoxications occur due to extensive use of cyanide compounds as reaction products. Smoke inhalation, a polyintoxication, is most often responsible for domestic cyanide poisonings. Suicidal poisonings are rare. Cyanogenic compounds may produce acute or subacute toxicity. Signs of cyanide poisoning include headache, vertigo, agitation, confusion, coma, convulsions and death. Definitive laboratory confirmation is generally delayed. Elevated plasma lactate, associated with cardiovascular collapse, should suggest cyanide intoxication. Immediate treatment includes 100% oxygen, assisted ventilation, decontamination, correction of acidosis and blood pressure support. Antidotes include oxygen, hydroxocobalamin, di-cobalt EDTA and methaemoglobin-inducers. Hydroxocobalamin is an attractive antidote due to its rapid cyanide binding and its lack of serious side-effects, even in the absence of cyanide intoxication. Sodium thiosulphate acts more slowly than other antidotes and is indicated in subacute cyanogen poisoning and as an adjunct to acute cyanide poisoning. Initial evaluation of antidotal efficacy is based on correction of hypotension and lactic acidosis; the final analysis rests on the degree of permanent central nervous system injury.

    Foci of myolysis of cardiac muscle fibers are suggested to be used for evaluation of thanatogenetic significance of ethanol concentration in cadaveric blood. This sign of acute ethanol poisoning is absent in case of other cause of death in a state of ethanol intoxication, even in the presence of high ethanolemia. Therefore, foci of myolysis are a sign of ethanol tolerance.

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

    Introduction Pediatric poisonings represent a major and preventable cause of morbidity and mortality throughout the world. Epidemiologic information about poisoning among children in many lower- and middle-income countries is scarce. This study describes the epidemiology of acute poisonings in children presenting to Ain Shams University's Poisoning Treatment Center (ASU-PTC) in Cairo and determines the causative agents and characteristics of acute poisoning in several pediatric age groups. Methods This retrospective study involved acutely poisoned patients, 0 to 18 years of age, who presented to the ASU-PTC between 1/1/2009 and 12/31/2013. Data were extracted from electronic records maintained by the ASU-PTC. Collected data included demographics, substance of exposure, circumstances of the poisoning, patient disposition, and outcome. Results During the 5-year study period, 38,470 patients meeting our criteria were treated by the ASU-PTC; 19,987 (52%) were younger than 6 years of age; 4,196 (11%) were 6 to 12 years; and 14,287 (37%) were >12 years. Unintentional poisoning accounted for 68.5% of the ingestions, though among adolescents 84.1% of ingestions were with self-harm intent. In all age groups, the most frequent causative drugs were non-opioid analgesics, antipyretics, and antirheumatics. The most common nonpharmaceutical agents were corrosives in preschool children and pesticides in adolescents. Most patients had no/minor effects (29,174 [75.8%]); hospitalization rates were highest among adolescents. There were 119 deaths (case fatality rate of 0.3), primarily from pesticide ingestion. Conclusion Poisoning in preschool children is mainly unintentional and commonly due to nonpharmaceutical agents while poisoning in adolescents is mainly intentional (self-harm). Pesticides, mainly organophosphorous compounds and carbamates, were the most frequent agent leading to morbidity and mortality. PMID:26653953

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.

    Objective To chart follow-up of patients after acute poisoning by substances of abuse, register whether patients referred to specialist health services attended, and whether patients contacted a general practitioner (GP) after the poisoning episode. Design Observational cohort study. Setting A primary care emergency outpatient clinic in Oslo, Norway. Subjects Patients ≥12 years treated for acute poisoning by substances of abuse were included consecutively from October 2011 to September 2012. Main outcome measures Follow-up initiated at discharge, proportion of cases in which referred patients attended within three months, and proportion of cases in which the patient consulted a GP the first month following discharge. Results There were 2343 episodes of acute poisoning by substances of abuse. In 391 (17%) cases the patient was hospitalised, including 49 (2%) in psychiatric wards. In 235 (10%) cases the patient was referred to specialist health services, in 91 (4%) advised to see their GP, in 82 (3%) to contact social services, in 74 (3%) allotted place in a homeless shelter, and in 93 (4%) other follow-up was initiated. In 1096 (47%) cases, the patient was discharged without follow-up, and in a further 324 (14%), the patient self-discharged. When referred to specialist health services, in 200/235 (85%) cases the patient attended within three months. Among all discharges, in 527/1952 (27%) cases the patient consulted a GP within one month. When advised to see their GP, in 45/91 (49%) cases the patient did. Conclusion Attendance was high for follow-up initiated after acute poisoning by substances of abuse. Key Points Despite poor long-term prognosis, patients treated for acute poisoning by substances of abuse are frequently not referred to follow-up.Nearly all patients referred to specialist health services attended, indicating the acute poisoning as an opportune moment for intervention.Advising patients to contact their GP was significantly associated with

    Social factors may affect the available sources of toxic substances and causes of poisoning; and these factors may change over time. Additionally, understanding the characteristics of patients with acute toxic poisoning is important for treating such patients. Therefore, this study investigated the characteristics of patients with toxic poisoning. Patients visiting one of 3 hospitals in 2003 and 2011 were included in this study. Data on all patients who were admitted to the emergency departments with acute toxic poisoning were retrospectively obtained from medical records. Total 939 patients were analyzed. The average age of patients was 40.0 ± 20 yr, and 335 (36.9%) patients were men. Among the elements that did not change over time were the facts that suicide was the most common cause, that alcohol consumption was involved in roughly 1 of 4 cases, and that there were more women than men. Furthermore, acetaminophen and doxylamine remained the most common poisoning agents. In conclusion, the average patient age and psychotic drug poisoning has increased over time, and the use of lavage treatment has decreased.

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

    Introduction: Acute corrosive poisonings are caused by ingestion of corrosive chemicals which are most commonly used as household agents. Intoxications with these kind of agents produce numerous and severe post-corrosive complications of the upper gastrointestinal tract. On the other hand, our experience showed that corrosive agents may also cause injuries of the respiratory system, which makes the treatment very hard and additionally complicates the severe clinical condition of the patient. Objective: The aim of the study is to show the incidence of respiratory complications in acute corrosive poisonings, the need of various clinical investigations and also the treatment and final outcome of these kind of poisoning. Methods: We retrospectively analyzed clinical records of 415 patients hospitalized and treated at the University clinic for toxicology and urgent internal medicine, in Skopje, Republic of Macedonia, in the period between 2007 and 2011. The protocol consisted of methods for analyzing the systemic complications, with an accent on the post-corrosive respiratory complications. Results: From the total number of patients even 98 (23.61%) exhibited systemic complications, from which 51 (52.04%) are respiratory complications. The majority of patients are female (n=40, 78.43%) and the most common complication is pneumonia (n=47). The youngest patient in this study was 14 and the oldest was 87 years old. Conclusion: Besides the gastrointestinal complications in the acute corrosive poisonings respiratory complications are also very often. They complicate the clinical state of patient and very often lead to fatal endings. PMID:24944527

    This article describes a recent case of ciguatera poisoning treated with intravenous mannitol. Mannitol has been used with good effect in non-controlled studies in acutely severely poisoned patients, but is not described in the treatment of chronic or milder poisoning. Our patient was a 35-year-old Niuean man who had eaten a ciguatoxic fish two weeks previously. His symptoms were not severe but were very unpleasant and restricted his ability to work. He was given a single dose of mannitol (0.66g/kg) as an intravenous infusion over two hours. His symptoms dramatically improved within 24 hours, and within a few days he felt virtually back to his former self. He experienced no side effects to the mannitol. It is suggested that intravenous mannitol may prove to be a useful treatment for mild to moderate ciguatera poisoning, and for patients who present late for treatment.

    Objectives The objective of this study was to assess the pattern and outcome of acute cholinesterase inhibitors substances (CIS) poisoning cases, in a cohort from a regional tertiary care hospital. Methods cases admitted in the Toxicology Clinic of “Sf. Spiridon” Emergency Clinic Hospital Iasi, Romania between 1983 and 2013 were studied. Results a total number of 606 patients were included. The reason for exposures was intentional in 70% of cases and the commonest route of poisoning was oral in 92.2%. The highest percent of cases was females (56.4), the age group 20–29 (25.4%) and the majority (66.7%) coming from rural areas, 28.2% being agricultural workers. 36.6% of cases were severe clinical forms. Overall mortality rates were 3.8%, more than half of the death patients (65.2%) had concomitant alcohol intake. It was a significant statistical association between decrease level of serum cholinesterase on admittance and severe forms (p 0.000) and between survival and deaths groups (p 0.000). The pattern of poisoning described by our retrospective study suggests that CIS poisoning are mainly preventable. The main effective goals for prevention are restriction in free accessibility to toxic pesticides, together with sustained efforts in education concerning the life-threatening danger of pesticide poisoning.

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

    Scuba diving is becoming an increasingly popular recreation. Divers are traveling further afield, often to remote dive locations. These locations are often home to poisonous marine creatures such as stonefish. A case of acute stonefish poisoning in a scuba diver is described, including his treatment, the difficulties encountered with his management and evacuation, and his subsequent return to full health. The proper management of stonefish poisoning is reviewed, and the implications for divers traveling to remote locations are given.

    In 1995-96, the Occupational Medicine Service of the province of Ragusa, Sicily, examined all cases of pesticide poisonings among persons seen in two local emergency departments, identifying 86 cases due to unintentional pesticide exposure. Methomyl, a highly toxic carbamate, was indicated for 51% of all cases. The most frequently reported symptoms included nausea and vomiting (48%), excessive perspiration (33%), and dyspnea (16%). Fifty-nine cases (69%) were hospitalized, 5 in intensive care. The methomyl cases occurred more frequently during summer months while the cases from all other pesticides showed no seasonal patterns. These observations point out the relevance of identifying acute pesticide poisonings in the province of Ragusa and suggest that ongoing registration of these events should be a public health priority.

    Hexavalent chromium compounds are most commonly used in printing, dyeing, plastics and rayon manufacturing. Poisoning in children by ammonium dichromate, an odorless and bright orange-red crystal, are rarely reported. Acute poisoning will result in death due to multi-organ failure. The target organs that are affected by this poison are the respiratory system, kidneys, liver, eyes and skin. On ingestion, initially there is a relative lack of severe symptoms and signs. Hence, the delay in seeking medical attention could lead to the increased rate of mortality. In this case study, we report the ingestion of ammonium dichromate by a child. Despite appropriate management, such as hepatic supportive measures and plasma transfusion, the toxicity progressed to multi-organ failure and death.

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

    The aim of this study was to examine epidemiologic data regarding acute herbicide or insecticide poisoning in adults from 2011 to 2014 at the national level in South Korea. Further, the association between governmental regulations involving pesticides and changes in pesticide poisoning occurrences over time was determined. Data were obtained from the emergency department (ED)-based Injury In-depth Surveillance system conducted by the Korea Center for Disease Control and Prevention (KCDC). Governmental regulations on pesticides were downloaded from the homepage of the Korea Rural Development Administration. Pesticides were classified according to guidelines provided by the World Health Organization (WHO) and by the respective Resistance Action Committee (RAC). Trends in the number of ED presentations and case fatality rate (CFR) due to pesticide poisoning were investigated. The overall CFR due to poisoning from herbicides or insecticides in adults in South Korea was 16.8% during 2011-2014. However, CFR significantly decreased over the 4-year period. The ED presentations of paraquat (PQ) poisoning fell significantly, whereas poisoning due to glyphosate, glufosinate, or combined herbicides increased markedly over the 4 years. Between 2011 and 2013, PQ was the most common pesticide poisoning, whereas glyphosate became the most frequent in 2014. PQ produced the highest rate of fatality followed by endosulfan. Although the frequency of PQ poisoning decreased, which may be attributed to governmental regulations, the CFR and incidence of pesticide poisoning in adults remain a public health concern that needs to be addressed.

    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.

    Abstract Self-induced poisoning with chemicals is one of the most commonly used suicide methods. Suicide attempts using massive pure sodium ferrocyanide and methanol are rare. This article discusses the management of acute intentional self-poisoning using sodium ferrocyanide and methanol. We present a case of acute self-induced poisoning using sodium ferrocyanide and methanol admitted to our hospital 2 hours after ingestion. He was deeply unconscious and unresponsive to painful stimuli. The laboratory findings showed acute kidney injury and severe metabolic acidosis. We took effective measures including endotracheal intubation and mechanical ventilation to ensure the vital signs were stable. Subsequently, we treated the patient using gastric lavage, bicarbonate, ethanol, plasmapheresis (plasma exchange), and continuous renal replacement therapy (CRRT) successfully. He gradually recovered from poisoning and was discharged without abnormalities on the 6th day. Follow-up for 3 months revealed no sequelae. Blood purification including plasmapheresis and CRRT is an effective method to scavenge toxicants from the body for acute self-poisoning with sodium ferrocyanide and methanol. Treatment strategies in the management of poisoning, multiple factors including the removal efficiency of toxin, the protection of vital organs, and the maintenance of homeostasis must be considered.

    Chemical food poisoning is a periodic menace both for the health of the consumers and for trade. It can be intentional or unintentional. In the latter case, poisoning may have a very large attack rate and it may be caused by sophistication (e.g., the methanol poisoning in Italy in 1985) or by environmental pollution (e.g., the Iraq accident in 1971-1972 due to mercury-contaminated flour). As a general statement, they are acute events, often noticed by outbreaks of unexplained deaths or sickness. The purposed lines for intervention (monitoring and biological testing) and some related problems are briefly described. Emphasis is placed on biological of suspected food items by a sensitive method to detect the presence of a noxious agent of unknown origin. The basic principle is to administer the highest amount possible of the suspected food to two different species of rodents for 5 days. Finally it should be noted that the characteristics and severity of every episode depend on the food and the chemical involved; thus only general suggestions may be given.

    Cases of deaths in manure or septic tanks are rare in legal-medical practice, more frequently as unfortunate occupational accidents. Poisoning with toxic gases, especially with hydrogen sulfide, is reported as the cause of death, while the exhaustion of oxygen in the air is omitted with the simultaneous excess of carbon dioxide. In such cases, determination of the direct cause of death constitutes a big problem because post-mortem examination does not reveal the specific changes. A case of acute collective poisoning by gases in a manure storage tank is presented of 5 agricultural workers, 2 of whom died. While explaining the cause of poisoning and deaths, toxicological blood tests were performed in the victims of the accident, as well as gases inside the manure storage tank. The post-mortem examinations and toxicological blood tests performed did not allow determination of the direct cause of death. Toxicological tests of gases from inside the manure tank showed a very low concentration of oxygen, with a simultaneous very high concentration of carbon dioxide, and a considerable level of hydrogen sulfide. The cause of fainting of three and deaths of two workers was not the poisoning with hydrogen sulfide, but oxygen deficiency in the air of the tank.

    Acute severe organophosphate poisoning is a serious complication seen in developing and agricultural countries. Pralidoxime and high dose atropine are the standard treatments. There is no consensus about acute severe organophosphate poisonings that are unresponsive to pralidoxime, atropine, and supportive therapies. We report a case of acute severe organophosphate poisoning that was unresponsive to standard treatments and successfully treated with high-volume continuous venovenous hemodiafiltration and therapeutic plasma exchange combined with lipid infusion.

    Most cases of acute hydrogen sulfide (H2S) poisoning in China are caused by sewage processing. With the rapid development of urbanization in China, H2S poisoning is showing an increasing trend. Here, we report a case of survival from severe H2S poisoning. A 40-year-old worker was found in the underground sewer lines. He was unresponsive with bilaterally dilated pupils and had poor oxygen saturation. After intubation, he was transferred to the intensive care unit. He developed respiratory failure, acute myocardial infarction, ventricular arrhythmia and left ventricular function impairment, requiring artificial ventilation with highly concentrated oxygen, hyperbaric oxygen treatment and drug therapy. Consequently, he completely recovered from the respiratory and cardiac failure. Cases of survival after severe H2S intoxication have been rarely reported. Such exposures may bring about severe myocardial impairment, which is most likely to benefit from angiotensin-converting enzyme inhibition and β-blocker.

    Limited work has focused on occupational exposures that may increase the risk of cyanide poisoning by ingestion. A retrospective chart review of all admissions for acute cyanide poisoning by ingestion for the years 1988 to 2008 was conducted in a tertiary university hospital serving the largest population in the country working in jewelry and textile facilities. Of the 9 patients admitted to the hospital during the study period, 8 (7 males, 1 female; age 36 ± 11 years, mean ± SD) attempted suicide by ingestion of potassium cyanide used in their profession as goldsmiths or textile industry workers. Five patients had severe neurologic impairment and severe metabolic acidosis (pH 7.02 ± 0.08, mean ± SD) with high anion gap (23 ± 4 mmol/L, mean ± SD). Of the 5 severely intoxicated patients, 3 received antidote therapy (sodium thiosulfate or hydroxocobalamin) and resumed full consciousness in less than 8 hours. All patients survived without major sequelae. Cyanide intoxication by ingestion in our patients was mainly suicidal and occurred in specific jobs where potassium cyanide is used. Metabolic acidosis with high anion is a good surrogated marker of severe cyanide poisoning. Sodium thiosulfate and hydroxocobalamin are both safe and effective antidotes.

    About 5% of the patients admitted to emergency departments with poisonings are seriously ill and need admission to intensive care units (ICUs). This paper presents the result of three multicentric studies carried out in Spain during the last ten years. A study was made of 6 ICUs in 1980, 41 in 1987 and 15 in 1990 with a total of 596 patients. The average age (36) remained stable throughout, but the number of female cases decreased each time. The most frequent cause (79%) was attempted suicide. The products used most frequently were therapeutic drugs (82, 71 and 58%) followed by drugs of abuse, and then agricultural, household and industrial products. We observed a progressive decrease in barbiturates (54, 15 and 2%) and an increase in benzodiazepines and cyclic antidepressants. Therapeutic methods used were mostly gastric lavage (64%), activated charcoal (35%), forced diuresis (43%), extracorporeal therapy (11%) and antidotes. The mortality rate fluctuated between 6.4 and 9.1%, being significantly higher with poisoning by non-therapeutic drugs. In conclusion, the most common poisoning admitted to our ICUs was by psychoactive drugs in suicide attempts. We observed the under-use of activated charcoal and an excessive usage of kidney and extracorporeal methods. The prognosis was worse for poisonings with non-therapeutic drugs.

    The median nerve somatosensory evoked potentials (SEP), pattern reversal visual evoked potentials (VEP), and brain stem auditory evoked potentials (BAEP) were studied in 109 healthy adults and in 88 patients with acute carbon monoxide (CO) poisoning. The upper limits for normal values of peak and interpeak latencies of multimodalities of evoked potentials in the reference group were established by a stepwise multiple regression analysis. SEP changes selectively affecting N32 and N60 were found in 78.8% of patients. There was prolonged PI00 latency of VEP in 58.2% of the cases examined. The prevalence of BAEP abnormalities in comatose patients (36%) was significantly higher than that (8.6%) in conscious patients. BAEP abnormalities were most frequently seen in comatose patients who had diminished brain stem reflexes (77.8%). It has been found that a consistent abnormality involving N2O and subsequent peaks in SEP, a remarkable prolongation of PI00 latency in VEP, or a prolongation of Ill-V interpeak latency in BAEP as well as the reoccurrence of evoked potential abnormalities after initial recovery all indicate unfavorable outcomes in patients with acute CO poisoning. The multimodality evoked potentials have proved to be sensitive indicators in the evaluation of brain dysfunction and in the prediction of prognosis of acute CO poisoning and the development of delayed encephalopathy. 16 refs., 4 figs., 6 tabs.

    Their frequency is estimated with difficulty, although on autopsy pulmonary edema is found almost routinely. It is a major complication of overdoses (48 p. 100 of severe intoxications). Their formation can be suspected, when after the first phase of respiratory depressions, with coma, myosis, and a variable latent period, a second attack of respiratory insufficiency occurs with tachypnea, and cyanosis. The chest X-ray shows diffuse alveolar infiltration, sparing the apices. The heart being generally of normal size. Rapid disappearance of this infiltrate (24 to 48 hours) enables the elimination of two diagnoses: pneumonia due to inhalation of gastric fluid, an infectious pneumonia. Their pathogenesis remains very debatable: - in the majority of cases abrupt L.V.F. can be eliminated: -on the other hand it could be an allergic accident of the anaphylactic type, or local liberation of histamine, or a local toxic action on the pulmonary capillaries; - hypoxia, secondary to respiratory depression, could lead to pulmonary edema, by the same mechanism as at altitude; - finally, owing to the central neurological disorders a neurogenic theory can be put forward. Their treatment is essentially a combination of Nalorphine with oxygen therapy (by mask, or if necessary by assisted, controlled ventilation) with prevention of inhalation of gastric fluid (gastric emptying) or curative treatment of possible aspiration by antibiotics, and cortico-steroids. Diuretics can be useful, as well as cardiotonics.

    Methods: This study concerns the third of a series of three examinations of hand strength and vibration thresholds in a two year period after acute OP poisoning among 48 Nicaraguan men. The first two examinations were performed at hospital discharge and seven weeks after poisoning, and the present examination two years later. Twenty eight cattle ranchers and fishermen who had never experienced pesticide poisoning were examined as controls, also three times over the two year period. The poisonings were categorised as caused by "non-neuropathic" OPs and "neuropathic" OPs, each subdivided in moderate and severe poisonings. Results: Men poisoned with OP insecticides had persistent reduced hand strength. We previously reported weakness at hospital discharge for OP poisoned in all categories that worsened seven weeks later for those severely poisoned with neuropathic OPs. Strength improved over time, but the poisoned were still weaker than controls two years after the poisoning, most noticeably among the subjects most severely poisoned with neuropathic OPs. Also, index finger and toe vibration thresholds were slightly increased at the end of the two year period, among men with OP poisonings in all categories, but patterns of onset and evolvement of impairment of vibration sensitivity were less clear than with grip and pinch strength. Conclusions: Persistent, mainly motor, impairment of the peripheral nervous system was found in men two years after OP poisoning, in particular in severe occupational and intentional poisonings with neuropathic OPs. This finding is possibly due to remaining organophosphate induced delayed polyneuropathy. PMID:14691285

    Organophosphate pesticides have emerged as a common cause of poisoning, particularly in developing countries. The most common electrocardiographic abnormalities observed in organophosphate poisoning are sinus tachycardia, QT interval prolongation, and, very rarely, ventricular arrhythmias. We report a case of organophosphate poisoning associated with atrial fibrillation, right bundle branch block, QT interval prolongation, and intermittent narrow QRS complexes that were most likely due to automaticity from the region of the left posterior fascicle.

    Carbon monoxide poisoning is potentially lethal, and early recognition and treatment is essential. An 18-year-old man was admitted due to syncope and a carboxyhaemoglobin level of 17% after water pipe tobacco smoking. He received normo- and hyperbaric oxygen as treatment and was discharged after two days without neurological sequelae. This case is the first in Denmark, but recently seven similar cases have been reported. The number of young people smoking water pipe tobacco is increasing, and we fear that more cases like this will occur in the future.

    Background Poisoning is becoming a real health care burden for developing countries like India. An improved knowledge of the patterns of poisonings, as well as the clinical course and outcomes of these cases can help to formulate better preventive and management strategies. Aim To study the demographic and clinical profiles of patients admitted to the ICU with acute poisoning and to study the factors that predict their mortality. Materials and Methods Retrospective two years (September 1, 2010 to August 31, 2012) study of all consecutive patients admitted to the Intensive Care Unit (ICU) with acute poisoning at a tertiary care hospital in Northern India. Results Out of the 67 patients admitted to the ICU during the study period, the majority were young (median age 29 years) males (69%) who had consumed poison intentionally. Pesticides were the most commonly employed poison, notably organophosphorus compounds (22 patients, 32.8%) and aluminium phosphide (14 patients, 20.9%). While the overall mortality from all poisonings was low (18%), aluminium phosphide was highly toxic, with a mortality rate of 35%. The factors at ICU admission that were found to be associated with a significant risk of death were, high APACHE II and SOFA scores (p =0.0001 and p=0.006, respectively), as well as the need for mechanical ventilation and drugs for vasoactive support (p=0.012 and p= 0.0001, respectively). Conclusion Use of pesticides for intentional poisoning continues to be rampant in Northern India, with many patients presenting in a critical condition to tertiary level hospitals. Pesticide regulations laws, educational awareness, counseling and poison information centers will help to curtail this public health problem. PMID:26557594

    Paraquat (PQ) is a highly toxic herbicide that harms the liver, kidney, lungs and heart, and results in a variety of complications. The majority of patients with severe PQ poisoning may succumb to multiple organ failure, and the mortality rate is high. Although a large number of studies have been performed investigating PQ poisoning, cases of mumps caused by PQ-induced poisoning are rare. In the present case report, a 45-year-old female who ingested PQ was admitted to the Emergency Department of Liaocheng People's Hospital (Liaocheng, China). During the development of the disease, mumps was caused by a cavity ulcer following PQ poisoning. To the best of our knowledge, cases of mumps following PQ poisoning are rare.

    Although many Asians regard puffer fish as a delicacy since ancient times, puffer fish (Lageocephalus scitalleratus) is also a well-known source of possibly lethal food poisoning. The fish is gaining popularity in Singapore and can be found in quite a few restaurants now. Puffer fish contains tetrodotoxin (TTX), a potent poison affecting the neural pathway. Puffer fish poisoning may cause a constellation of symptoms, such as giddiness, numbness and tingling sensation of the mouth, paresthesia, and muscle weakness. Severe cases may present with respiratory depression, circulatory failure, and death. TTX poisonings have been reported in Japan, Taiwan, Hong Kong, Bangladesh, and the United States (Haque et al. 2008). We report a case of mild poisoning and suggest observation for such cases.

    Objective To evaluate potential oxidative stress in patients with acute phosphide poisoning and the effect of vitamin C. Methods Participants were females and divided into three groups; group I: healthy volunteers group II: healthy volunteers received vitamin C, group III: patients with acute phosphide poisoning received the supportive and symptomatic treatment and group IV: patients with acute phosphide poisoning received the supportive and symptomatic treatment in addition to vitamin C. All the participants were subjected to thorough history, clinical examination, ECG and laboratory investigations were carried on collected blood and gastric lavage samples on admission. Blood samples were divided into two parts, one for measurement of routine investigations and the second part was used for evaluation of malondialdehyde and total thiol levels before and after receiving the treatment regimen. Results Most of the cases in this study were among the age group of 15–25 years, females, single, secondary school education, from rural areas and suicidal. All vital signs were within normal range and the most common complaint was vomiting and abdominal pain. All cases in this study showed normal routine investigations. The mean MDA levels after receiving treatment decreased significantly in groups II and IV. The mean total thiol levels increased significantly after receiving treatment in groups II and IV. Conclusion It can be concluded that vitamin C has a potential benefit due to its antioxidant property on zinc phosphide induced-oxidative stress in acute zinc phosphide poisoned patients.

    BACKGROUND--There is little information on the incidence of acute lung injury or changes in the pulmonary circulation in acute liver failure. The aim of this study was to record the incidence of acute lung injury in fulminant hepatic failure caused by paracetamol poisoning, to document the associated pulmonary circulatory changes, and to assess the impact of lung injury on patient outcome. METHODS--The degree of lung injury was retrospectively assessed by a standard scoring system (modified from Murray) in all patients with fulminant hepatic failure caused by paracetamol poisoning, admitted to the intensive care unit over a one year period. The severity of liver failure and illness, other organ system failure, and patient outcome were also analysed. RESULTS--Twenty four patients with paracetamol-induced liver failure were admitted and nine developed lung injury of whom eight (33%) had severe injury (Murray score > 2.5). In two patients hypoxaemia contributed to death. Patients with lung injury had higher median encephalopathy grades (4 v 2 in the non-injured group) and APACHE II scores (29 v 16). Circulatory failure, requiring vasoconstrictor support, occurred in all patients with lung injury but in only 40% of those without. Cerebral oedema, as detected by abnormal rises in intracranial pressure, also occurred in all patients with lung injury but in only 27% of the non-injured patients. The incidence of renal failure requiring renal replacement therapy was similar in both groups (67% and 47%). Pulmonary artery occlusion pressures were normal in the lung injury group. Cardiac output was high (median 11.2 1/min), systemic vascular resistance low (median 503 dynes/s/cm-5), and pulmonary vascular resistance low (median 70 dynes/s/cm-5), but not significantly different from the group without lung injury. Mortality was much higher in the lung injury group than in the non-injured group (89% v 13%). CONCLUSIONS--Acute lung injury was common in patients with paracetamol

    Abstract Background: Tetramine (tetramethylene disulphotetramine, TETS) and fluoroacetamide (FAA) are known as illegal rodenticides with high toxicity to animal species and human beings, which could lead to severe clinical features, including reduction of consciousness, convulsions, coma, and even death. Methods and Results: We presented 2 cases that involved rodenticides poisoning. Even though the patients showed severe manifestations, they were initially misdiagnosed, resulting in 2 persons finally died from TETS and FAA poisoning in homicide cases. Conclusion: From the clinical and forensic experience of these 2 cases, we suggest that physicians should consider TETS and FAA poisoning when patients present generalized seizures, especially in some cases without clear cause and diagnosis of disease. Early diagnosis and treatment are essential for positive management and criminal investigation in intentional poisoning cases. Moreover, clinical toxicology education should be reinforced.

    The objective of the present study was to improve forensic medical diagnostics of the cases of death associated with morphine poisoning based on the investigation into the biochemical changes in blood and pericardial fluid as well as morphological changes in the myocardial structures. The studies were carried out with the use of thin-layer chromatography, colorimetric and morphological methods including hematoxylin and eosin, Lee's methylene blue, and van Gieson's picrofuscin staining. These techniques were supplemented by light and polarization microscopy. The study has demonstrated the presence of morphine in 99.16% of the blood and pericardial samples obtained in the cases of poisoning. The comparison of the results of biochemical and pathomorphological studies of the myocardium made it possible to evaluate the functional and morphological conditions of the heart in the case of acute morphine poisoning during the period of chronic drug intoxication.

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

    ABSTRACT The clinical syndrome of rhabdomyolysis is caused by injury of skeletal muscles resulting in release of intracellular muscle constituents. Drug poisoning is one of the causes of severe rhabdomyolysis. Severe electrolyte disorders and acute renal failure may occur in rhabdomyolysis, leading to life-threatening situations. Early initiation of renal replacement therapy can help improve outcome. In the present retrospective study, medical records of 181 patients suspected of rhabdomyolysis from Loghman-Hakim Hospital in the period of 2004 to 2005 were reviewed. A creatinine phosphokinase (CPK) value of greater than five times normal (>/=975 IU/L) was the basis for confirmation of a rhabdomyolysis diagnosis. An increased serum creatinine level of more than 30% was the basis for acute renal failure diagnosis. Out of 156 patients, 100 were male with an age range of 13 to 78 years. One hundred and two (92%) patients had CPK >975 U/L, and 36 patients (28.6%) had a 30% or more increase in their creatinine level during their admission days. Mean fluid intake was the same in patients with renal failure and those without renal failure. In 8.3% of the cases, multiple drug poisoning was observed. The most common compound overdose associated with rhabdomyolysis was opium. It is concluded that fluid therapy alone is not adequate in the management of acute renal failure in rhabdomyolysis. Therefore, other etiological factors are involved that remain to be elucidated by further studies.

    Background Lead is a metal that has no biological function useful for the human body. In Korea, non-occupational exposure to lead has mostly occurred through taking oriental medicine. However, in this paper we report a case of lead poisoning caused by ingesting talisman material. Case presentation A 16-year-old male patient complained of severe abdominal pain after taking cinnabar, a talisman material. He was diagnosed with lead poisoning accompanied by acute hepatitis. We confirmed that the cinnabar the patient took contained about 10% elemental lead. After symptom management, the patients’ symptoms, liver function test results, and blood lead concentration level improved. Conclusion Lead poisoning can be accompanied by hepatitis, although rarely. As we have confirmed that cinnabar as a talisman material is harmful to the human body, measures to prevent its misuse are needed. PMID:24472628

    Organophosphorus (OP) pesticides are a broad class of acetylcholinesterase inhibitors that are responsible for tremendous morbidity and mortality worldwide, contributing to an estimated 300,000 deaths annually. Current pharmacotherapy for acute OP poisoning includes the use of atropine, an oxime, and benzodiazepines. However, even with such therapy, the mortality from these agents is as high as 40%. It is increasingly recognized that not all OPs are the same. Significant differences exist in their toxicity, lipophilicity, and response to oxime therapy. Other non-muscarinic effects of OP pesticides exist, such as acute and chronic neuromuscular junction failure and central respiratory failure. In part because most of the mortality from these chemicals takes place in the developing world, little National Institutes of Health (NIH) research has been directed towards these agents. However, the similar mechanism of action of OP pesticides and the military nerve agents, along with increasing concerns about chemical terrorism has lead to the formation of the NIH Countermeasures Against Chemical Threats (CounterACT) Program. As part of the CounterACT Program, the NIH has recently designated six OP pesticides as "threat agents". This concept paper describes some of the knowledge gaps related to non-muscarinic effects of OP pesticides and highlights needed areas of further research. Leveraging the current NIH interest in these chemicals to medical necessities in the developing world offers the possibility of delivering new therapeutics where they are needed on a daily basis.

    α-Pyrrolidinovalerophenone (α-PVP) is a synthetic cathinone belonging to the group of "second generation" pyrrolidinophenones that becomes more and more popular as a designer psychostimulant. Here we provide toxicological analytical support for a severe poisoning with α-PVP. Serum and urine samples that were sent to our laboratory were subjected to a general unknown screening procedure. The procedure includes immunoassay-based screening of drugs of abuse in serum and systematic toxicological analysis of urine and serum after neutral and basic liquid-liquid extraction followed by gas chromatography-mass spectrometry (GC-MS). Whereas the immunoassay delivered negative results, analyzing the urine sample by GC-MS in full scan mode disclosed the presence of α-PVP and its metabolites α-(2″-oxo-pyrrolidino)valerophenone (2″-oxo-α-PVP) and 1-phenyl-2-(pyrrolidin-1-yl)pentan-1-ol (OH-α-PVP). In the acetylated urine sample we found additionally N,N-bis-dealkyl-PVP. In serum, α-PVP could be detected after solid phase extraction and a concentration of 29ng/mL was determined. Other forensic relevant substances were not detected. The presented data can explain the psychotic symptoms and behavioural pattern of the subject after abuse of α-PVP, leading to a clinical condition similar to excited delirium syndrome.

    Ciguatera poisoning causes mainly gastrointestinal and neurological effects of variable severity. However, symptoms of peripheral neuropathy with paresthesias and paradoxical disturbance of thermal sensation are the hallmark. Electrophysiological studies are often normal, except in severe cases. We report four people who developed mild ciguatera poisoning after barracuda ingestion. Electrophysiological studies documented normocalcemic latent tetany. These findings are consistent with ciguatoxin's mechanism of toxicity, which involves inactivation of voltage-gated Na(+) channels and eventually increases nerve membrane excitability.

    Aluminum phosphide (AlP) is a solid fumigant widely used in Iran as a grain preservative. When reacted with water or acids, AIP produces phosphine gas, a mitochondrial poison that interferes with oxidative phosphorylation and protein synthesis. Poisoning by AIP is one of the most important causes of fatal chemical toxicity in Iran. There are few studies in the medical literature addressing prognostic factors associated with AlP poisoning. In this prospective study conducted across a 14-month period commencing on 21st March 2006, we enrolled all patients admitted to the ICU of Loghman-Hakim Hospital Poison Center (Tehran, Iran) with AIP poisoning, no history of diabetes mellitus diagnosed before hospitalization, and normal body mass index. We recorded patient-specific demographic information, blood glucose level on presentation (before treatment), arterial blood gas (ABG) analysis, time elapsed between ingestion and presentation, ingested dose, duration of intensive care admission, and outcome data related to each presentation. We enrolled the group of patients who survived the intoxication as a control group and compared their blood glucose levels with those who died because of AlP poisoning. Data were analyzed by Statistical Product and Service Solutions (SPSS) software (Version 12; Chicago, Ilinois, USA) using logistic regression, Pearson correlation coefficient and Student's t-test. P values of 0.05 or less were considered as the statistical significant levels. Forty-five patients (21 women and 24 men) with acute AlP poisoning were included in the study. The mean age was 27.3 +/- 11.5 years (range: 14-62 years). Thirteen patients survived (29%) and 32 expired (71%). AlP poisoning followed deliberate ingestion in all patients. The time elapsed between ingestion and arrival at the hospital was 3.2 +/- 0.4 h. There was no significant difference between survived and non-survived groups according to age, gender, and time to treatment. However, the difference between

    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.

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

    Ingestion of paraquat causes multi-organ failure. Prognosis is best estimated through measurement of blood paraquat concentrations but this facility is not available in most hospitals. We studied the prognostic significance of abnormal pancreatic enzymes for survival. Patients with acute paraquat poisoning were recruited. An extensive series of blood tests including serum amylase were serially checked. Patients were sorted according to their serum amylase activity (normal [<220 U/L], mildly elevated [220 to 660 U/L], elevated [>660 U/L]), and survival compared between groups. 177 patients were enrolled to the study, of whom 67 died and 110 survived. 122 (70.62%), 27 (15.25%) and 25 (14.13%) patients were in the normal, mildly elevated and elevated amylase activity groups, respectively. The case fatality in the elevated group was 100% compared to 17% in the normal group (P < 0.001). We found four independent factors for paraquat death prediction: amylase, PaCO2, leukocyte number, and neutrophil percentage. Models using pancreatic enzyme activity showed good prediction power. We have found that abnormal pancreatic enzymes are useful prognostic marker of death after acute paraquat poisoning. Including serum amylase activity into a prognostic model provides a good prognostication.

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

    Small numbers of the papers have studied the association between organophosphate (OP) poisoning and the subsequent acute kidney injury (AKI). Therefore, we used the National Health Insurance Research Database (NHIRD) to study whether patients with OP poisoning are associated with a higher risk to have subsequent AKI.The retrospective cohort study comprised patients aged ≥20 years with OP poisoning and hospitalized diagnosis during 2000-2011 (N = 8924). Each OP poisoning patient was frequency-matched to 4 control patients based on age, sex, index year, and comorbidities of diabetes, hypertension, hyperlipidemia, chronic obstructive pulmonary disease, coronary artery disease, and stroke (N = 35,696). We conducted Cox proportional hazard regression analysis to estimate the effects of OP poisoning on AKI risk.The overall incidence of AKI was higher in the patients with OP poisoning than in the controls (4.85 vs 3.47/1000 person-years). After adjustment for age, sex, comorbidity, and interaction terms, patients with OP poisoning were associated with a 6.17-fold higher risk of AKI compared with the comparison cohort. Patients with highly severe OP poisoning were associated with a substantially increased risk of AKI.The study found OP poisoning is associated with increased risk of subsequent AKI. Future studies are encouraged to evaluate whether long-term effects exist and the best guideline to prevent the continuously impaired renal function.

    Black ducks and mallards were found to be highly susceptible to phosphorus poisoning. 3 mg. of white phosphorus per kg. of body weight given in a single dose resulted in death of a black duck in 6 hours. Pathologic changes in both acute and chronic poisoning were studied. Data are presented showing that diagnosis can be made accurately by chemical analysis of stored tissues in cases of phosphorus poisoning.

    Tetraethyl lead (TEL) poisoning has declined sharply with decreasing consumption of gasoil and other chemicals contained TEL. Here we reported group TEL poisoning in the plastic weaving factory. We investigated 16 cases with the typical nerves disorder which is similar to organotin poisoning, and the result suggested that the poisoning may cause by applied “white oil” contented TEL. Despite its rareness, our cases emphasize that clinicians should pay attention to the difference from the treatment of organic tin poisoning. PMID:27162692

  14. Is there a relationship between the blood cholinesterase and QTc interval in the patients with acute organophosphate poisoning?

    Organophosphates cause poisoning as a result of the excessive accumulation of acetylcholine at the cholinergic synapses due to inhibition of acetylcholinesterase (ChE). In the literature, it has been reported that there have been electrocardiographic abnormalities, including QT-interval prolongation in most patients with acute organophosphate poisoning (OPP), and a relation between blood ChE level and clinical severity in acute OPP. The aim of this study is to assess the relationship between blood ChE level and QTc interval in the patients with acute OPP. This retrospective study consists of 20 patients admitted to the emergency intensive care unit. A total of 93 QTc interval and blood ChE measures obtained on the same day from 20 cases were compared for their correlation. There were prolonged QTc intervals in 35.4% of the ECGs. There was a negative correlation between QTc interval and blood ChE measures. In following up the patients with acute OPP, QTc interval may be useful when blood ChE levels are low and may provide complementary information concerning the severity of poisoning. However, further prospective studies, supporting the present results, are needed.

    Organophosphorus and carbamate pesticides are cholinesterase (ChE) inhibiting chemicals that have been responsible for avian die-offs. Identification of chemicals implicated in these die-offs is difficult and sometimes conclusions are solely circumstantial. However, when marked depression (inhibition) of brain ChE activity accompanies organophosphorus or carbamate residues in body tissues or ingesta, cause-effect diagnosis is enhanced. To achieve this end, normal brain ChE activity is estimated for controls of the affected species and then die-off specimens are individually evaluated for evidence of ChE inhibition. This approach to evaluation of antiChE poisoning may also be used to monitor exposure of vertebrates to field application of organophosphorus or carbamate pesticides. Problems associated with this kind of evaluation, and the main topic of this report, include variability of brain ChE activity among species, postmortem influences of ambient conditions (storage or field) on ChE activity, and differential patterns of ChE activity when inhibited by organophosphorus or carbamate compounds. Other topics discussed are the ChE assay procedure, example case reports and interpretation, and research needed for improving the diagnostic utility of ChE activity in a field situation.

    This article describes a case of Chinaberry tree poisoning diagnosed in a dog. The initial clinical signs were variable and included tremors (muscular seizures) and a moderate limp in the dog's back leg, which evolved to a more severe condition in the following hours. Abdominal radiographic evaluation was requested, and abundant small, foreign, radio-dense bodies were detected, which were associated with Chinaberry tree fruits after surgical extraction. Adequate treatment was established, and the patient recovered completely. In addition, we compare clinical and gross postmortem findings in other similar cases reported in the literature. There is a general lack of information of such poisoning in pets.

    Introduction The aim of this study was to investigate the relationship between the admission blood glucose level following acute poisoning, severity of acute poisoning and clinical outcome. Material and methods This prospective study was conducted on 345 deliberate self-poisoning patients. Standard demographic and clinical information; admission blood glucose level; poisoning severity score and outcome were recorded. Patients with a history of diabetes mellitus, receipt of pre-sampling intravenous dextrose solution or glucocorticoids, and poisoning with toxic agents which produce hyper- or hypoglycaemia were excluded. Results Mean age of the patients was 27.5 ±8.6 years. Females outnumbered males (57.9%). Oral ingestion of more than one drug (46.7%) and opiates (14.2%) were the main causes of poisoning. Blood glucose values ranged from 50 mg/dl to 396 mg/dl. Hyper- and hypoglycaemia were observed in 23.8% and 13.91% respectively. A total of 24.41% and 22.92% of the patients in hyper- and hypoglycaemic groups had grade 3 and 4 severity score in comparison with 4.18% in the normoglycaemic group. Development of complications and death were 14.64% and 10.42% in patients with hyper- and hypoglycaemia versus 3.73% in patients with normoglycaemia. A significant difference between normoglycaemic and hyperglycaemic patients in the severity of poisoning and clinical outcome was observed (P < 0.001). Conclusions Admission blood glucose levels may have a relationship with the severity of poisoning and clinical outcome following acute poisoning. PMID:22291737

    Ammonium dichromate is an inorganic compound frequently used in screen and color printing. Being a strong oxidizing agent, it causes oxygen free radical injury resulting in organ failure. We report a 25-year-old female who presented with acute kidney injury after consumption of ammonium dichromate. She was managed successfully with hemodialysis and supportive measures. This case is reported to highlight the toxicity of ammonium dichromate.

    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.

  20. Medical treatment of acute poisoning with organophosphorus and carbamate pesticides.

    Organophosphorus compounds (OPs) are used as pesticides and developed as warfare nerve agents such as tabun, soman, sarin, VX and others. Exposure to even small amounts of an OP can be fatal and death is usually caused by respiratory failure. The mechanism of OP poisoning involves inhibition of acetylcholinesterase (AChE) leading to inactivation of the enzyme which has an important role in neurotransmission. AChE inhibition results in the accumulation of acetylcholine at cholinergic receptor sites, producing continuous stimulation of cholinergic fibers throughout the nervous systems. During more than five decades, pyridinium oximes have been developed as therapeutic agents used in the medical treatment of poisoning with OP. They act by reactivation of AChE inhibited by OP. However, they differ in their activity in poisoning with pesticides and warfare nerve agents and there is still no universal broad-spectrum oxime capable of protecting against all known OP. In spite of enormous efforts devoted to development of new pyridinium oximes as potential antidotes against poisoning with OP only four compounds so far have found its application in human medicine. Presently, a combination of an antimuscarinic agent, e.g. atropine, AChE reactivator such as one of the recommended pyridinium oximes (pralidoxime, trimedoxime, obidoxime and HI-6) and diazepam are used for the treatment of OP poisoning in humans. In this article the available data related to medical treatment of poisoning with OP pesticides are reviewed and the current recommendations are presented.

    Of a total of 205 poisoning deaths in our hospital in 2003, 83 cases were due to Aluminium phosphide poisoning and were further analyzed. Most vulnerable age group was 21-40 years and M:F ratio was 2:1. On naked eye examination, almost all the vital organs were found to be congested. On microscopic study, the liver showed central venous congestion, degeneration, haemorrhage, sinusoidal dilation, bile stasis, centrilobular necrosis, Kupffer cell hyperplasia, infiltration by mononuclear cells and fatty change. Microscopy of the lungs revealed alveolar thickening, oedema, dilated capillaries, collapsed alveoli and haemorrhage. In the kidney, changes were degeneration, infiltration, tubular dilation and cloudy swelling. Changes in the brain included congestion and coagulative necrosis and in the stomach, congestion and haemorrhage. Easy availability of this cheap and highly toxic substance was responsible for the sudden spurt of poisoning with aluminium phosphide.

    The duration of hemodialysis (HD) in methanol poisoning (MP) is dependent on the methanol concentration, the operational parameters used during HD, and the presence and severity of metabolic acidosis. However, methanol assays are not easily available, potentially leading to undue extension or premature termination of treatment. Here we provide a prediction model for the duration of high-efficiency HD in MP. In a retrospective cohort study, we identified 71 episodes of MP in 55 individuals who were treated with alcohol dehydrogenase inhibition and HD. Four patients had residual visual abnormality at discharge and only one patient died. In 46 unique episodes of MP with high-efficiency HD the mean methanol elimination half-life (T1/2) during HD was 108 min in women, significantly different from the 129 min in men. In a training set of 28 patients with MP, using the 90th percentile of gender-specific elimination T1/2 (147 min in men and 141 min in women) and a target methanol concentration of 4 mmol/l allowed all cases to reach a safe methanol of under 6 mmol/l. The prediction model was confirmed in a validation set of 18 patients with MP. High-efficiency HD time in hours can be estimated using 3.390 × (Ln (MCi/4)) for women and 3.534 × (Ln (MCi/4)) for men, where MCi is the initial methanol concentration in mmol/l, provided that metabolic acidosis is corrected.

    Aconitum napellus is an extremely dangerous plant that contains various toxic diterpenoid alkaloids, mainly aconitine primarily concentrated in the roots. We report a case of acute intoxication of a 21-year-old man admitted to our Emergency Department after the ingestion, in order to sleep, of three homemade Aconitum napellus capsules. Capsules were measured to contain 237 mg of root and 19 microg of aconitine. The patient experienced the first symptoms on wakening 5 hours later with generalized paresthesia, nausea, diarrhea, vertigo, thoracic pain dyspnea, and dyschromatopsia. At admission, 7 hours after intake electrocardiographic analysis showed a sinusal bradycardia with polymorphic and bigeminal ventricular extrasystolia. Cardiovascular and neurological symptoms disappeared, respectively within 11 and 13 hours of ingestion. The patient was discharged from the ICU on day 2. Plasmatic concentrations at H7, H9, H14 H19, and after ingestion were, respectively, of 1.75, 0.75, 0.35, and 0.02 ng/mL. The calculated half-life of aconitine was 3 hours. To our knowledge, this is the first reported case with an aconitine toxicokinetic-effect relationship. The authors stress that clinicians must be aware of possible occurrence of acute poisoning with Aconitum napellus in European countries and in the United States as herbal medicine is becoming increasingly popular.

    Elemental mercury exposure occurs frequently and is potentially a toxic, particularly in children. Children are often attracted to elemental mercury because of its color, density, and tendency to form beads. Clinical manifestations of elemental mercury intoxication vary depending on its form, concentration, route of ingestion, and the duration of exposure. We present data on 179 pediatric cases of elemental mercury poisoning from exposure to mercury in schools in two different provinces of Turkey. Of all patients, 160 children had both touched/played with the mercury and inhaled its vapors, while 26 children had only inhaled the mercury vapor, two children reported having tasted the mercury. The median duration of exposure was 5 min (min 1-max 100), and 11 (6 %) children were exposed to the mercury for more than 24 h at home. More than half of the children (51.9 %) were asymptomatic at admission. Headache was the most common presenting complaint. The results of physical and neurological examinations were normal in 80 (44.6 %) children. Mid-dilated/dilated pupils were the most common neurological abnormality, and this sign was present in 90 (50.2 %) children. Mercury levels were measured in 24-h urine samples daily, and it was shown that the median urinary level of mercury was 29.80 μg/L (min, 2.40 μg/L; max, 4,687 μg/L). A positive correlation was also found between the duration of exposure and urinary mercury levels (r = 0.23, p = 0.001). All patients were followed up for 6 months. On the first follow-up visit performed 1 month after discharge, the neurological examinations of all patients were normal except for those patients with peripheral neuropathy and visual field defects. On the last follow-up visit at the sixth month, only two children still experienced visual field defects. In conclusion, this study is one of the largest case series of mercury intoxication of students in schools. Elemental mercury exposure can be potentially toxic, and its

    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 C max 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.

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

    Antidotes for toxicological emergencies can be life-saving. However, there is no nationwide estimation of the antidotes stocking amount in Korea. This study tried to estimate the quantities of stocking antidotes at emergency department (ED). An expert panel of clinical toxicologists made a list of 18 emergency antidotes. The quantity was estimated by comparing the antidote utilization frequency in a multicenter epidemiological study and the nation-wide EDs' data of National Emergency Department Information System (NEDIS). In an epidemiological study of 11 nationwide EDs from January 2009 to December 2010, only 92 (1.9%) patients had been administered emergency antidotes except activated charcoal among 4,870 cases of acute adult poisoning patients. Comparing with NEDIS data, about 1,400,000 patients visited the 124 EDs nationwide due to acute poisoning and about 103,348 adult doses of the 18 emergency antidotes may be required considering poisoning severity score. Of these, 13,224 (1.9%) adult doses of emergency antidotes (575 of atropine, 144 of calcium gluconate or other calcium salts, 2,587 of flumazenil, 3,450 of N-acetylcysteine, 5,893 of pralidoxime, 287 of hydroxocobalamin, 144 of sodium nitrite, and 144 of sodium thiosulfate) would be needed for maintaining the present level of initial treatment with emergency antidotes at EDs in Korea.

    OBJECTIVES: To describe the epidemiology of carbon monoxide (CO) poisoning in a defined population, identifying those at greatest risk from acute poisoning resulting in admission to hospital or death. METHODS: A retrospective study with routinely collected information, set in the former West Midlands Regional Health Authority; population of 5.2 million. The data comprised 939 deaths and 701 hospital admissions due to CO poisoning between January 1988 to December 1994. The main outcome measures were age and sex standardised incidence rates (SIRs) for non-intentional, suicidal, and undetermined poisonings for health authorities and the linear relation with socioeconomic deprivation. RESULTS: Overall rate of non-intentional poisonings over the 7 year period was 7.6/100,000, an annual rate of 1.1/100,000. The 7 year rates were highest in people > or = 85; men 24.0/100,000 and women 19.7/100,000. For suicides the 7 year rate was 19.6/100,000, an annual rate of 2.8/100,000. The 7 year rates were highest for men of 35-39, 64.1/100,000, and for women aged 45-49, 15.3/100,000. None of the causes of poisoning were related to deprivation. Non-intentional poisonings showed a strong seasonal variation with the highest rates being recorded in the months October to March. Increased rates of poisoning were found in the rural districts of the West Midlands. There seems to have been a decline in suicides coinciding with the introduction of three way catalytic converters on cars. CONCLUSIONS: Elderly people and the very young are at the greatest risk from non- intentional CO poisoning and rates are highest in the winter months. Although deaths from non-intentional CO poisoning are declining nationally, in the West Midlands they have remained stable and hospital admissions are increasing. It is not solely an urban phenomenon with rates for non-intentional CO poisoning and suicides higher in the rural districts. Health authorities need to consider all populations in any prevention

    Retrograde amnesia is a recognised neurological complication of carbon monoxide poisoning. This article describes the case of a female found dead in her bath where initial post-mortem findings and the surrounding circumstances raised strong suspicions of homicide, especially when there was contradictory evidence from her husband who was the only other person present. He was later diagnosed as having retrograde amnesia between his two visits to the bathroom to attend to his wife which caused him to merge them into one event, thus arousing suspicions of foul play. The discussion explores the current clinical views on non-fatal carbon monoxide poisoning as well as problems of interpretation of information derived from case work.

    Acute organophosphate (OP) poisoning causes respiratory failure through two mechanisms: central apnea and pulmonary dysfunction. The vagus nerve is involved in both the central control of respiratory rhythm as well as the control of pulmonary vasculature, airways and secretions. We used a rat model of acute OP poisoning with and without a surgical vagotomy to explore the role of the vagus in OP-induced respiratory failure. Dichlorvos (2,2-dichlorovinyl dimethyl phosphate) injection (100mg/kg subcutaneously, 3 x LD50) resulted in progressive hypoventilation and apnea in all animals, irrespective of whether or not the vagi were intact. However, vagotomized animals exhibited a more rapidly progressive decline in ventilation and oxygenation. Artificial mechanical ventilation initiated at onset of apnea resulted in improvement in oxygenation and arterial pressure in poisoned animals with no difference between vagus intact or vagotomized animals. Our observations suggest that vagal mechanisms have a beneficial effect during the poisoning process. We speculate that vagally mediated feedback signals from the lung to the brainstem serve as a modest protective mechanism against central respiratory depressive effects of the poison and that bulbar-generated efferent vagal signals do not cause sufficient pulmonary dysfunction to impair pulmonary gas exchange.

    The International Code of Conduct on the Distribution and Use of Pesticides of the Food and Agriculture Organization (FAO) of the United Nations has been for 20 years the most acknowledged international initiative for reducing negative impact from pesticide use in developing countries. We analyzed pesticide use and poisoning in Central America, particularly in Costa Rica and Nicaragua, and evaluated whether registration decisions are based on such data, in accordance with the FAO Code. Extensive use of very hazardous pesticides continues in Central America and so do poisonings with organophosphates, carbamates, endosulfan and paraquat as the main causative agents. Central American governments do not carry out or commission scientific risk assessments. Instead, guidelines from international agencies are followed for risk management through the registration process. Documentation of pesticide poisonings during several decades never induced any decision to ban or restrict a pesticide. However, based on the official surveillance systems, in 2000, the ministers of health of the seven Central American countries agreed to ban or restrict twelve of these pesticides. Now, almost 4 years later, restrictions have been implemented in El Salvador and in Nicaragua public debate is ongoing. Chemical and agricultural industries do not withdraw problematic pesticides voluntarily. In conclusion, the registration processes in Central America do not comply satisfactorily with the FAO Code. However, international regulatory guidelines are important in developing countries, and international agencies should strongly extend its scope and influence, limiting industry involvement. Profound changes in international and national agricultural policies, steering towards sustainable agriculture based on non-chemical pest management, are the only way to reduce poisonings.

    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.

    Since 1995, Nicaragua has adopted several legal instruments to comply with children's rights, including international conventions and a minimum working age of 14 years. However, records from the Ministry of Health's Pesticide Program show continuing occupational acute pesticide poisonings (APP) among children five to 14-years-old from 1995 to 2006. We reviewed and described all reported APPs and estimated the yearly incidence and underreporting rates. Of 2069 APP cases, 432 were occupational. Annual incidence rates (range: 1-4.7/100,000) have been decreasing since 1997. Six fatal and most non-fatal cases were related to work in tobacco and basic grain crops. Based on underreporting data, we estimate actual incidence during the period studied to be 18,516 (95% CI, 3840-33,204) cases among five- to fourteen-year-olds. With regard to child labor and pesticide exposure, children's rights violations still exist and must be abolished in both formal employment and in the informal economy, including in family-based agricultural activities.

    A case of serial killing by poisoning by a 59-year-old practical nurse is discussed. Following a report by an emergency-room doctor of an attempted murder, police performed an investigation into all deaths of patients in the nurse's care. Earlier, a medico-legal cause-of-death investigation had been performed on two of these cadavers, but in the other three cases the death certificate had been issued after a medical investigation only. In two of these latter cases, the body had been cremated, but fixed histological samples taken at medical autopsy were available, while in one case the person had died recently and the body was thereafter exhumed and autopsied. All of the suspected victims were older people who required nursing, and the nurse's course of action was consistent in all cases. In the absence of ordinary post-mortem toxicology samples in the medical cases, extraordinary evidence--paraffin-embedded liver tissue samples originally taken for histology at autopsy--was successfully recovered in two cases and analyzed for drugs. In all five cases, drugs not prescribed to the patient were detected, including digoxin, dixyrazine, citalopram, venlafaxine, and benzodiazepines (diazepam, chlordiazepoxide, temazepam, and oxazepam). The nurse was eventually found guilty of five murders by poisoning, five attempted murders, and three aggravated assaults. The nurse was sentenced to life imprisonment.

    The objective of this study was to explore work-related risk factors of acute occupational pesticide poisoning among male farmers according to the severity of the poisoning. A nationwide sampling survey of male farmers was conducted in South Korea in 2011. A total of 1,958 male farmers were interviewed. Severity of occupational pesticide poisoning in 2010 was evaluated according to symptoms, types of treatment, and number of pesticide poisoning incidents per individual. A multinomial logistic regression model was used to estimate the odds ratio with 95% confidence intervals for risk factors of acute occupational pesticide poisoning. We found that the risk of acute occupational pesticide poisoning increased with lifetime days of pesticide application (OR = 1.74; 95% CI = 1.32-2.29), working a farm of three or more acres in size (OR = 1.49), not wearing personal protective equipment such as gloves (OR = 1.29) or masks (OR = 1.39). Those who engaged in inappropriate work behaviors such as not following pesticide label instructions (OR = 1.61), applying the pesticide in full sun (OR = 1.48), and applying the pesticide upwind (OR = 1.54) had a significantly increased risk of pesticide poisoning. There was no significant risk difference by type of farming. In addition, the magnitude of these risk factors did not differ significantly by severity of acute pesticide poisoning. In fact, our findings suggest that work-related risk factors contributed to the development of acute occupational pesticide poisoning without relation to its severity. Therefore, prevention strategies for reducing occupational pesticide poisoning, regardless of severity, should be recommended to all types of farming and the level of poisoning severity.

    Abstract Background: Lead is a toxic element of the environment which leads to major complications once it enters the blood stream, affecting multiple organs and systems of the body. Methods: We present the case of a 16-year-old girl, diagnosed with lead poisoning after occupational exposure due to the fact that the girl was actively involved in the family's pottery business. History revealed that the girl participated in the process of pottery, her father was also diagnosed with lead poisoning 2 years before. The patient's personal history underlined that approximately 1 year ago she presented with severe abdominal pain, being diagnosed with acute appendicitis and she underwent appendectomy, but the pain persisted, thus due to family history of lead poisoning, the suspicion of saturnine colic rose, and she was diagnosed with lead poisoning. The main symptoms and signs were severe abdominal pain, vomiting, and arterial hypertension. The clinical evolution was favorable under symptomatic treatment and chelation therapy. Results: Lead toxicity is a life-threatening condition because of its severe acute and chronic complications. In children, there is no safe blood lead level, prevention methods are, therefore, very important in order to avoid toxic multiorganic effects of this metal. Conclusion: Even though the diagnosis of lead poisoning remains difficult in children, it must also be taken into consideration by the clinician facing a child with gastrointestinal or neurological involvement.

    Paraquat and diquat are classified as bipyridyl compounds not only leads to acute organ damage, but also to a variety of complications. Patients with severe paraquat-induced poisoning may succumb to multiple organ failure involving the circulatory and respiratory systems. Deliberate self-poisoning with paraquat continues to be a major public health concern in many developing countries. At present there is no specific antidote to paraquat poisoning, hence the need to more focus on prevention and in cases of poisoning aggressive decontamination to prevent further absorption. This article presented a 12-year-old male with acute kidney injury following the ingestion of paraquat in suicidal attempt and serves to explore the complications associated with paraquat poisoning and current recommended treatment PMID:27689124

  2. Acupuncture for poison ivy contact dermatitis. A clinical case report.

    1988-01-01

    Poison ivy contact dermatitis is fairly common in the suburbia of this country among amateur gardeners and children. It commonly inflicts its poison on the exposed parts of the limbs. The vesicular or bullous skin lesions are quite disturbingly itchy. Scratching the itchy lesions often spreads the condition by transplanting the remanent resinous toxin to other parts of the body. Though they are usually self-limiting, the intense itch is the main motivation for a patient to seek medical care. The conventional treatment is basically ineffective. During the summer of 1987 we treated four such cases of dermatitis with acupuncture upon their request to mollify their unbearable itch. They originally consulted with us for other problems. There were three males and one female. Their ages were between 29 and 63. Three cases were relatively mild and the fourth one was fairly severe. In the milder cases, their itch subsided in a few hours and skin lesions were healed in about two days after one treatment. In the severe case the itch subsided in about two days and most of the skin lesions dried up in four days after the first treatment and were healed almost completely after three sessions of acupuncture treatment. The plausible anti-inflammatory mechanism of acupuncture with the involvement of ACTH and/or cortisol was discussed.

    The present study was undertaken with a view to improving forensic medical diagnostics of intoxication with poisonous mushrooms in the cases of patients' death in a hospital. A total of 15 protocols of forensic medical examination of the corpses of the people who had died from acute poisoning were available for the analysis. The deathly toxins were amanitin and muscarine contained in various combinations in the death cap (Amanita phalloides) and the early false morels (Gyromitra esculenta and G. gigas). The main poisoning season in the former case was May and in the latter case August and September (93.4%). The mortality rate in the case of group intoxication (such cases accounted for 40% of the total) amounted to 28.6%. 40% of the deceased subjects consumed mushrooms together with alcohol. The poisoning caused the development of either phalloidin- or gyromitrin-intoxication syndromes (after consumption of Amanita phalloides and Gyromitra esculenta respectively). It is emphasized that the forensic medical experts must substantiate the diagnosis of poisoning with mushroom toxins based on the results of the chemical-toxicological and/or forensic chemical investigations. The relevant materials taken from the victim or the corpse should be dispatched for analysis not only within the first day but also on days 2-4 after intoxication. The mycological and genetic analysis must include the detection and identification of mushroom microparticles and spores in the smears from the oral cavity, vomiting matter, wash water, gastric and intestinal contents. In addition, the macro- and microscopic morphological signs, clinical data (major syndromes, results of laboratory studies, methods of treatment) should be taken into consideration as well as the time (season) of mushroom gathering, simultaneous poisoning in a group of people, and other pertinent information.

    Paraquat poisoning is very severe. Most victims, including those who have ingested a small amount, will die from Paraquat poisoning. The cause of death in the majority of such cases is lung fibrosis. Paraquat poisoning in patients with positive human immunodeficiency virus (HIV) infection status has seldom been reported. Herein, we report a case of an HIV patient with Paraquat poisoning who had an excellent outcome even without standard treatment. Currently, only 3 such cases have been reported in the literature and in each case there was a good outcome, which was not expected according to predictive models. A possible mechanism may involve the relative lack of functional macrophages in HIV patients, which would tend to result in much less severe lung injury. None of the available predictive models of Paraquat poisoning appear to be appropriate for HIV patients.Paraquat poisoning in HIV patients may have better survival due to less lung injury.

    Although exposure to animal venom and poison, such as snakebites, bee stings, and contact, with toads, is a common problem, reported deaths are rare. The present report discusses 18 fatal cases in China. Causes of death were grouped into 6 categories, including 1 case of tetrodotoxin poisoning, 1 case of gallbladder poisoning, 3 cases of snake venom toxicity, 4 cases of melittin toxicity, 4 cases of cantharidin poisoning and 5 cases of venenum bufonis poisoning. The epidemiology of each venom-induced death, the mechanism of exposure to venom, and the target organs and tissues affected by these toxic animals were here systematically reviewed. Such details are important to even suspected cases of venom damage. The associated problems related to forensic medicine, such as manner of death and possible attribution to the toxic effects of various animals, are also discussed herein.

    Background: Poisoning is a major public health problem and is one of the most frequent causes of emergency hospital admissions. The aim of this study was to identify the main risk factors for unintentional childhood poisoning in Tehran, Iran and to suggest possible causes and preventative measures. Methods: In this case-control study (case, n=140; control, n=280), two controls were selected for every case. Controls were matched by age, sex, and date of hospital attendance. All children and their guardians were then interviewed by the same person using a standard questionnaire that covered the demographic, behavioral, and risk factors associated with accidental poisonings. Results: The most common type of poisoning was related to narcotics (58.6%); and among the narcotics, methadone was the most prevalent poisoning agent (74.7%). Multivariate conditional logistic regression model revealed that addiction in the family (OR=14.6; 95% CI:6.2-34.6), previous poisoning (OR=7; 95% CI:2.4- 20.2), maternal occupation (OR=4; 95% CI:1.3- 12.3), and inaccessibility of poisoning products (OR=0.03; 95% CI:0.01- 0.12) were the main risk factors in unintentional childhood poisoning. Conclusion: Addiction in the family as a risk factor and inaccessibility of poisoning products as a protecting factor were recognized to have the highest correlation with the unintentional child poisoning. These two factors were considered as priorities in health education programs. PMID:27453885

    Cantharidin is a poisonous substance secreted by blister beetles, including the ‘Spanish fly’. Historically, cantharidin was used as an aphrodisiac, vesicant and abortifacient. Symptoms of poisoning include gastrointestinal and genitourinary mucosal irritation along with renal dysfunction. We present the case of a reckless 23-year-old soldier who accepted the challenge of eating a beetle (Berberomeloe majalis). Six hours later he was admitted to the emergency room with abdominal pain, dysuria, gross haematuria with clots, hypotension, fever and renal insufficiency. With intravenous fluid therapy, he recovered clinically. Laboratory parameters returned to normal within 1 week. PMID:26019851

    Substance poisoning, such as toluene intoxication, has seldom been reported in the relevant literature. The documented cerebral neuroimaging has mostly described reversible symmetrical white matter changes in both the cerebral and cerebellar hemispheres. This paper presents 2 patients with toluene poisoning, whose brain magnetic resonance imaging studies showed a similar picture that included extra involvement over the corpus callosum; however, such corpus callosum involvement has never been mentioned and is quite rare in the literature. We discussed the underlying neuropathological pathways in this article. Hopefully, these cases will provide first-line clinicians with some valuable information with regard to toluene intoxication and clinical neuroimaging presentations.

    Despite improvements to intensive care management and specific pharmacological treatments (atropine, oxime, diazepam), the mortality associated with organophosphate (OP) poisoning has not substantially decreased. The objective of this examination was to describe the role of fresh frozen plasma (FFP) in acute OP poisoning. After a deliberate ingestion of malathion, a 55-year-old male suffering from miosis, somnolence, bradycardia, muscular fasciculations, rales on auscultation, respiratory insufficiency, as well as from an inhibition of red blood cell acetylcholinesterase (AChE) and plasma butyrylcholinesterase (BuChE), was admitted to hospital. Malathion was confirmed in a concentration of 18.01 mg L(-1). Apart from supportive measures (including mechanical ventilation for four days), antidotal treatment with atropine, oxime-pralidoxime methylsulphate (Contrathion(R)), and diazepam was administered, along with FFP. The potentially beneficial effects of FFP therapy included a prompt increase of BuChE activity (from 926 IU L(-1) to 3277 IU L(-1); reference range from 7000 IU L(-1) to 19000 IU L(-1)) and a reduction in the malathion concentration, followed by clinical recovery. Due to BuChE replacement, albumin content, and volume restitution, FFP treatment may be used as an alternative approach in patients with acute OP poisoning, especially when oximes are not available.

    Two cases of acute valproic acid poisoning with central nervous system depression and raised ammonia level without hepatotoxicity were reported. They were treated successfully with the use of the antidotes: L-carnitine and other supportive measures. Clinical manifestation and progress was described, and discussion is focused on the use of L-carnitine in valproic acid-induced hyperammonemia, from its mechanism to the clinical experiences in the literature. Based on the favorable response of our two cases and the literature review, we recommend the administration of intravenous L-carnitine in patients of valproic acid overdose with hyperammonemia or valproic acid-induced hyperammonemic encephalopathy and hepatotoxicity at a dose of 50 mg/kg every 8 h for the first initial 24 h with further individual assessment.

    Introduction. Overdose of potassium is not as frequently encountered in clinical practice as hyperkalaemia due to acute or chronic renal disease. However, potassium overdoses leading to serious consequences do occur. Case Presentation. A 20-year-old nurse student presented with a cardiac arrest with asystole rhythm. Beside the patient were found four 50-mL syringes and empty vials of potassium chloride (20 mL, 10%). After initial resuscitation with epinephrine, 125 mL of a 4.2% intravenous solution of sodium bicarbonate were injected which resulted in the recovery of an effective cardiac activity. The patient recovered without sequelae. Conclusion. The difficulty in this case was to recognize the potassium poisoning. The advanced resuscitation with the use of a specific treatment helped to resuscitate the patient. PMID:23326708

    Background Intoxication with Amanita phalloides is associated with high morbidity and mortality. Treatment therapies include general support, toxin elimination, pharmacotherapy with agents such as the hepatoprotective agent silibinin, and, in extreme states, liver transplantation. Despite these therapeutic interventions, mortality remains relatively high. Case Reports We present reports of 2 patients with severe hepatic failure following intoxication with Amanita phalloides. Both patients were admitted to the intensive care unit; 1 patient suffered from hepatic failure solely, and the second patient experienced severe 5-organ failure. In addition to conventional intensive care treatment, both patients were treated additively with classical homeopathy. The 2 patients survived without any residual pathological sequelae. Conclusion Based on the 2 cases, including 1 extreme situation, we suggest that adjunctive homeopathic treatment has a role in the treatment of acute Amanita phalloides–induced toxicity following mushroom poisoning. Additional studies may clarify a more precise dosing regimen, standardization, and better acceptance of homeopathic medicine in the intensive care setting. PMID:24940137

    2013-01-01

    Although renal calcium crystal deposits (nephrocalcinosis) may occur in acute phosphate poisoning as well as type 1 renal tubular acidosis (RTA), hyperphosphatemic hypocalcemia is common in the former while normocalcemic hypokalemia is typical in the latter. Here, as a unique coexistence of these two seperated clinical entities, we report a 30-yr-old woman presenting with carpal spasm related to hypocalcemia (ionized calcium of 1.90 mM/L) due to acute phosphate poisoning after oral sodium phosphate bowel preparation, which resolved rapidly after calcium gluconate intravenously. Subsequently, type 1 RTA due to Sjögren's syndrome was unveiled by sustained hypokalemia (3.3 to 3.4 mEq/L), persistent alkaline urine pH (> 6.0) despite metabolic acidosis, and medullary nephrocalcinosis. Through this case report, the differential points of nephrocalcinosis and electrolyte imbalances between them are discussed, and focused more on diagnostic tests and managements of type 1 RTA.

    A 62-year-old male died of colchicine poisoning after accidental ingestion of Colchicum autumnale (meadow saffron). He ate a salad of plant with green leaves regarded as wild garlic (Allium ursinum). A few hours later he developed symptoms of gastroenteritis and was admitted to hospital. In spite of gastric lavage, activated charcoal and supportive measures, multi-organ system failure developed over the next two days. Laboratory analysis showed highly elevated blood concentrations of hepatic enzymes, creatine kinase, lactate dehydrogenase and blood urea nitrogen, as well as leukocytopenia and thrombocytopenia. Mechanical ventilation, dopamine, noradrenaline, crystalloid solutions and fresh frozen plasma were applied but despite treatment the patient died five days after the ingestion. Post-mortem examination revealed hepatic centrilobular necrosis, nephrotoxic acute tubular necrosis, petechial bleeding in fatty tissue, blunt and shortened intestinal villi and cerebral toxic edema. Botanical identification of incriminated plant gave Colchicum autumnale which confirmed colchicine poisoning. Although the accidental ingestion of Colchicum autumnale is rare and to our knowledge only five such cases have been described in detail, this is the second fatal case in Croatia described in the last 3 years.

    Sodium azide poisonings are a rare reason for hospitalization in toxicological units. They are observed as rarely as once within a number of years per hospital. Consequently, an algorithm for the optimum procedure of treating such intoxications does not exist and, as a result, there is a need to describe every single clinical case. A female, aged 55, was directed to the toxicological unit from a county hospital after swallowing four tablets of sodium azide, 150 mg each, in the form of preservative for fresh milk samples. Two hours after the incident a gastric lavage was performed and the tableting blend was retrieved. In the clinical examination higher concentration of lactic acid, ALAT and TSH were observed. In the ECG record unspecific aberrations in the ST segment were noticed. Due to the patient's general good condition and the fact that the tableting blend had been retrieved from the gastric rinse, further use of the antidote indicated in the therapy of cyanide intoxications was abandoned. Symptomatic treatment was used along with the patient's eight-day observation. In the described case the early decontamination prevented the development of acute poisoning.

    A 66-year-old man suffered the symptoms of severe lead poisoning for 2 years before diagnosis. The man had a blood lead level (PbB) on admission to hospital of 98 microg/dL. A detailed investigation revealed that the poisoning occurred as a result of drinking a homemade red wine, for which analyses showed a lead concentration up to 14 mg/L--70 times the Australian maximum limit for lead in wine. The source of the lead was a highly corroded enamel bathtub in which grape crushings and juice were stored for a week prior to bottling. The corrosion of the enamel surface of the bathtub had resulted in pitted patches up to 1 mm in depth along the side of the bathtub. Powdering of the tub surface was evident below a level where wine had been in contact with the sides of the tub. The homemade wine had a pH of 3.8, which would have greatly contributed to the solubilization of metals from the glaze. We conducted a test in which commercial red wine of similar pH and containing < 0.2 mg/L lead was placed in this tub for 7 days. Subsequent testing revealed a lead level of 310 mg/L. This high lead concentration is consistent with the surface area of enamel on the bathtub being in contact with a small liquid volume as in the case of the leaching test using commercial red wine. This case study highlights the importance of the use of food-grade materials for the preparation and storage of homemade beverages or food. PMID:11335194

    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

    Mitochondria are essential for survival. Their primary function is to support aerobic respiration and to provide energy for intracellular metabolic pathways. Paraquat is a redox cycling agent capable of generating reactive oxygen species. The aim of the present study was to evaluate changes in cortical and striatal mitochondrial function in an experimental model of acute paraquat toxicity and to compare if the brain areas and the molecular mechanisms involved were similar to those observed after chronic exposure. Sprague-Dawley rats received paraquat (25 mg/Kg i.p.) or saline and were sacrificed after 24 h. Paraquat treatment decreased complex I and IV activity by 37 and 21 % respectively in striatal mitochondria. Paraquat inhibited striatal state 4 and state 3 KCN-sensitive respiration by 80 % and 62 % respectively, indicating a direct effect on respiratory chain. An increase of 2.2 fold in state 4 and 2.3 fold in state 3 in KCN-insensitive respiration was observed in striatal mitochondria from paraquat animals, suggesting that paraquat redox cycling also consumed oxygen. Paraquat treatment increased hydrogen peroxide production (150 %), TBARS production (42 %) and cardiolipin oxidation/depletion (12 %) in striatal mitochondria. Also, changes in mitochondrial polarization was induced after paraquat treatment. However, no changes were observed in any of these parameters in cortical mitochondria from paraquat treated-animals. These results suggest that paraquat treatment induced a clear striatal mitochondrial dysfunction due to both paraquat redox cycling reactions and impairment of the mitochondrial electron transport, causing oxidative damage. As a consequence, mitochondrial dysfunction could probably lead to alterations in cellular bioenergetics.

    Organophosphate (OP) and carbamate (CM) are the most commonly used pesticides against insects. Little is known regarding the relationship between dementia and acute OP and CM poisoning. A nationwide population-based cohort study was conducted from the National Health Insurance Research Database in Taiwan. The incidence and relative risk of dementia were assessed in patients hospitalized for acute OP and CM poisoning from 2000 to 2011. The comparison cohort was matched with the poisoned cohort at a 4:1 ratio based on age, sex, and the year of hospitalization. During the follow-up period, the incidence of dementia was 29.4 per 10,000 person-years in the poisoned group, and represented a 1.98-fold increased risk of dementia compared with the control cohort (95% confidence interval, 1.59-2.47). This study provides evidence on the association between dementia and acute OP and CM poisoning. Regular follow-up of poisoned patients for dementia is suggested.

    OBJECTIVES: To assess in a developing Asian country the impact of pesticide regulation on the number of deaths from poisoning. These regulations, which were implemented in Sri Lanka from the 1970s, aimed to reduce the number of deaths - the majority from self-poisoning - by limiting the availability and use of highly toxic pesticides. METHODS: Information on legislative changes was obtained from the Ministry of Agriculture, national and district hospital admission data were obtained from the Sri Lanka Health Statistics Unit, and individual details of deaths by pesticide poisoning were obtained from a manual review of patients' notes and intensive care unit records in Anuradhapura. FINDINGS: Between 1986 and 2000, the total national number of admissions due to poisoning doubled, and admissions due to pesticide poisoning increased by more than 50%. At the same time, the case fatality proportion (CFP) fell for total poisonings and for poisonings due to pesticides. In 1991_92, 72% of pesticide-induced deaths in Anuradhapura were caused by organophosphorus (OP) and carbamate pesticides - in particular, the WHO class I OPs monocrotophos and methamidophos. From 1991, the import of these pesticides was reduced gradually until they were banned for routine use in January 1995, with a corresponding fall in deaths. Unfortunately, their place in agricultural practice was taken by the WHO class II organochlorine endosulfan, which led to a rise in deaths from status epilepticus - from one in 1994 to 50 in 1998. Endosulfan was banned in 1998, and over the following three years the number of endosulfan deaths fell to three. However, at the end of the decade, the number of deaths from pesticides was at a similar level to that of 1991, with WHO class II OPs causing the most deaths. Although these drugs are less toxic than class I OPs, the management of class II OPs remains difficult because they are, nevertheless, still highly toxic, and their toxicity is exacerbated by the paucity

    Two of the approximately 100 large, mature, red drum found dead or dying in Florida's Indian River and Mosquito Lagoon were examined. Determinations were made of serum electrolyte concentrations, total proteins, albumins, globulins, creatinine values, and enzyme activity. Concentrations of copper, zinc, arsenic, chromium, cadmium, mercury, lead, and selenium were determined by atomic aborption. The outstanding histological lesions were found in the gills of a moribund specimen. Results indicate that the acute episode was triggered by ingestion of copper, zinc, and arsenic. However, cadmium, mercury and chromium may have been contributory by binding with metallothionein and thus lowering tolerance to metal poisoning. (JMT)

    The first well-documented outbreak of acute methyl mercury (MeHg) poisoning by consumption of contaminated fish occurred in Minamata, Japan, in 1953. The clinical picture was officially recognized and called Minamata disease (MD) in 1956. However, 50 years later there are still arguments about the definition of MD in terms of clinical symptoms and extent of lesions. We provide a historical review of this epidemic and an update of the problem of MeHg toxicity. Since MeHg dispersed from Minamata to the Shiranui Sea, residents living around the sea were exposed to low-dose MeHg through fish consumption for about 20 years (at least from 1950 to 1968). These patients with chronic MeHg poisoning continue to complain of distal paresthesias of the extremities and the lips even 30 years after cessation of exposure to MeHg. Based on findings in these patients the symptoms and lesions in MeHg poisoning are reappraised. The persisting somatosensory disorders after discontinuation of exposure to MeHg were induced by diffuse damage to the somatosensory cortex, but not by damage to the peripheral nervous system, as previously believed.

  5. Legalon® SIL: the antidote of choice in patients with acute hepatotoxicity from amatoxin poisoning.

    More than 90% of all fatal mushroom poisonings worldwide are due to amatoxin containing species that grow abundantly in Europe, South Asia, and the Indian subcontinent. Many cases have also been reported in North America. Initial symptoms of abdominal cramps, vomiting, and a severe cholera-like diarrhea generally do not manifest until at least six to eight hours following ingestion and can be followed by renal and hepatic failure. Outcomes range from complete recovery to fulminant organ failure and death which can sometimes be averted by liver transplant. There are no controlled clinical studies available due to ethical reasons, but uncontrolled trials and case reports describe successful treatment with intravenous silibinin (Legalon® SIL). In nearly 1,500 documented cases, the overall mortality in patients treated with Legalon® SIL is less than 10% in comparison to more than 20% when using penicillin or a combination of silibinin and penicillin. Silibinin, a proven antioxidative and anti-inflammatory acting flavonolignan isolated from milk thistle extracts, has been shown to interact with specific hepatic transport proteins blocking cellular amatoxin re-uptake and thus interrupting enterohepatic circulation of the toxin. The addition of intravenous silibinin to aggressive intravenous fluid management serves to arrest and allow reversal of the manifestation of fulminant hepatic failure, even in severely poisoned patients. These findings together with the available clinical experience justify the use of silibinin as Legalon® SIL in Amanita poisoning cases.

    Background Poisoning is a common presentation in the emergency department. Oral exposures to organophosphorus compounds are especially frequent in rural and agricultural regions of South Asia and throughout the developing world. Case presentation Here we report a case of deliberate self-harm with an organophosphorus pesticide via the relatively uncommon parenteral route. A young woman injected herself with chlorpyriphos. Although the cholinergic effects were mild, cellulitis and abscess development were noted as a result. Conclusion Resource limited agricultural countries like Nepal present health care workers with numerous challenges in poisoning management. This case represents a rare but potentially morbid method of agrochemical poison exposure. PMID:24321121

    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.

    Dofetilide is a class III antiarrhythmic used for treating atrial dysrhythmias. Though its adverse effects are well described in routine use, very little is known about dofetilide toxicity in overdose. This is a retrospective case series of consecutive patients reported to our poison center after dofetilide overdose. Twenty-seven cases were included. Seventeen patients were treated at a healthcare facility, and of these, eight were admitted. Twenty-one patients took one extra capsule, four took someone else's medication, one took three extra capsules, and one had a large intentional overdose. Ten patients had co-ingestants reported, including three QT-prolonging agents. No one required cardioversion, defibrillation, CPR, or overdrive pacing. The patient who reported taking 90 times his usual dose in suicide attempt was the only patient to have significant clinical effects. He experienced an 8-beat run of non-sustained ventricular tachycardia, frequent multifocal PVCs, and ventricular bigeminy. He received magnesium sulfate and potassium chloride supplementation. In this series, unintentional small overdoses did not result in significant clinical effects and were often managed successfully at home, despite the fact that information showing a single capsule can cause torsades. This study is limited by its small sample size, retrospective design, and reliance on incomplete information.

    BACKGROUND Herbicides are commonly ingested for self-harm; however, relatively little has been published on poisoning with herbicides other than paraquat and glyphosate. We report here a case series of patients with acute exposure to a combination herbicide (brand name Tiller Gold or Whip Super) containing the selective phenoxy herbicide fenoxaprop-P-ethyl, the sulfonylurea herbicide ethoxysulfuron and the safener isoxadifen ethyl. METHOD Clinical data on all patients presenting with Tiller Gold or Whip Super poisoning to two General Hospital in Sri Lanka from 2002-2008 were collected prospectively until discharge. RESULTS Eighty-six patients with a history of Tiller Gold or Whip Super ingestion were included. The median time to presentation was 4 hours post-ingestion (IQR 2 to 10 hrs) and the median volume ingested was 22.5ml (IQR: 20-60; n=64). Most patients demonstrated limited clinical signs of poisoning and none required mechanical ventilation or intensive care treatment. The main clinical features were an epigastric burning sensation and vomiting; however, most of those who vomited had received gastric lavage or forced emesis. Eight patients had a reduced level of consciousness on admission (GCS 9 -14) that resolved without intervention over several hours. Only symptomatic and supportive care was required. The median hospital stay was 1 day (IQR: 1 to 2) and the case fatality was zero (95% CI: zero to 4.2%). This low case fatality compared favorably with the case fatality of other common herbicides in our cohort: paraquat >40%, propanil >10%, 4-chloro-2-methylphenoxyacetic acid (MCPA) > 5% and glyphosate >2%. CONCLUSION This combination herbicide product appears to be safe in patients with acute self-poisoning, particularly in comparison with other herbicides, and causing few clinical features PMID:19663557

    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.

    Hydrogen sulfide (H2S) is the second leading cause of toxin-related deaths in the operational site. Its main target organs of toxic effects are the central nervous system and respiratory system. In this study, we developed a serum metabonomic method, based on gas chromatography-mass spectrometry (GC/MS), to evaluate the effect of acute poisoning by hydrogen sulfide on rats. Pattern recognition analysis, including both principal component analysis (PCA) and partial least squares-discriminate analysis (PLS-DA), revealed that acute hydrogen sulfide poisoning induced metabolic perturbations. Compared to the control group, the level of urea, glucose, glyceryl stearate in rat serum of the poisoning group increased after two hours, and the level of glucose, docosahexaenoic acid, glyceryl stearate and arachidonic acid in rat serum of the poisoning group increased after 48 h, while the L-valine, galactose, L-tyrosine levels decreased. Our results indicate that metabonomic methods based on GC/MS may be useful to elucidate acute hydrogen sulfide poisoning through the exploration of biomarkers.

    Nitrobenzene is a nitrite compound often used in polishes or solvents. Its toxic effects are due to its ability to induce methaemoglobinaemia. The clinical presentation of this poisoning varies according to the concentration of methaemoglobin level in blood. The importance of early identification of the compound on the basis of clinical suspicion corroborative with methaemoglobin level with timely intervention is required to prevent fatal outcome. It is also important to take care of the secondary cycling of nitrobenzene from body stores to prevent secondary recurrence of symptoms in patients after heavy exposure. Here author reports a rare case of accidental poisoning with nitrobenzene presented with respiratory distress and cyanosis. On investigation, he was diagnosed to have cardiogenic pulmonary oedema and multiorgan dysfunction. The urgent institution of methylene blue as specific antidote along with haemodynamic and ventilatory support was proved crucial for life saving of the patient.

    The present report describes two cases of paraquat poisoning by skin absorption. The cases involved contractual workers who were spraying paraquat in an orchard. Whilst spraying, some solution adhered to their skin. The skin developed erythema followed by blistering and hemorrhaging hemorrhagic diabrosis. Six days later the patients were admitted to the Department of Poisoning and Occupational Disease, Qilu Hospital of Shandong University (Jinan, China) with 3 and 2% total body surface area (TBSA) burns, respectively. Surgical debridement was performed and immunosuppressants were administered during the patients’ treatment. The patients were treated successfully and had made a complete recovery following 21 days. From these cases it was examined how paraquat may cause skin injuries and occasionally poisoning. To the best of our knowledge, cases of paraquat poisoning are rare in China. A review of the relevant literature was performed. PMID:24250726

    This study aimed to observe the clinical curative effect of penehyclidine hydrochloride (PHC) combined with hemoperfusion in treating acute severe organophosphorus pesticide poisoning. We randomly divided 61 patients with severe organophosphorus pesticide poisoning into an experimental group (N = 31) and a control group (N = 30), and we compared the coma-recovery time, mechanical ventilation time, healing time, hospital expenses, and mortality between the two groups. The coma-recovery time, mechanical ventilation time, and healing time were lower in the experimental group than in the control group (P < 0.05), while the hospitalization expenses were higher in the experimental group than in the control group (P < 0.01); moreover, no significant difference was observed in the mortality rate between the two groups. Thus, PHC combined with hemoperfusion exerts a better therapeutic effect in acute severe organophosphorus pesticide poisoning than PHC alone.

    Datura stramonium L. (DS) is a wild-growing plant widely distributed and easily accessible. It contains a variety of toxic anticholinergic alkaloids such as atropine, hyoscamine, and scopolamine. Voluntary or accidental ingestion can produce severe anticholinergic poisoning. We report an unusual case of DS intoxication occurring in a geophagous young child after accidental ingestion of the plant. Our case is original because of the young age of the victim and the underlying geophagia facilitating the occurrence of poisoning.

    Mercury has a number of unique and fascinating properties. It is present in the environment in several forms, both organic and inorganic. Each of these forms has somewhat unique properties that differentiate them from the other forms, but all are toxic to humans in one way or the others. Mercury has been proven to be a potential source of poisoning in children as a result of the inappropriate handling of a liquid mercury. The cases of metallic mercury vapor intoxication not associated with occupational exposure may occur in school science laboratories, from mercury dust and powders, from latex paint containing a mercury-based fungicide, and from normal wear or installation of dental amalgam fillings. Another source of toxic mercury exposure can be broken thermometers, barometers, or sphygmomanometers that may occur in the home, and children are often victims of environmental exposure. In this paper, we present three members of a family who were exposed to mercury brought home from school by a family member. Since the mercury exposure was not known, the initial presentation and clinical picture suggested a misdiagnosis, a contagious infectious disease, because the onset of symptoms occurred at different times in the same family members. A subsequent change to a diagnosis of mercury intoxication and chelation therapy with meso-2,3-dimercaptosuccinic acid was started.

    We report a fatal case of combined α-pyrrolidinovalerophenone (α-PVP) and 2-(methylamino)-1-phenylpentan-1-one (pentedrone) poisoning. A 28-year-old man was taken to hospital in asystole. Despite resuscitation efforts over 30 min, he died. The forensic autopsy showed pulmonary edema and moderately advanced atherosclerotic lesions of the arteries. Microscopic observation revealed chronic changes in the heart. Confirmation of the presence of pentedrone, α-PVP, and its metabolite 1-phenyl-2-(pyrrolidin-1-yl)pentan-1-ol (OH-α-PVP) in tissues and fluids were achieved using gas chromatography-mass spectrometry analysis after liquid-liquid extraction. A quantitative validated liquid chromatography-mass spectrometry method was used to determine the concentrations of the above designer drugs in postmortem samples. Pentedrone, α-PVP, and OH-α-PVP concentrations were 8,794, 901 and 185 ng/mL in whole blood, respectively; 100,044, 2,610 and 2,264 ng/g in the liver, respectively; 22,102, 462 and 294 ng/g in the kidney, respectively; 13,248, 120 and 91 ng/g in the brain, respectively and 500,534, 4,190 and 47 ng/g in the stomach contents, respectively. This is the first known reported death attributed to the combined use of α-PVP and pentedrone. Additionally, this article is the first to report the distribution of pentedrone in postmortem human samples.

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

    We report the case of a 56-year-old woman who was accidentally poisoned when she ingested choke cherries whose pulp contained cyanide, and describe the acute clinical picture, the neurological sequelae and the neuroradiological findings. After recovery from coma, the patient showed signs of a parkinsonian syndrome, retrobulbar neuritis and sensory-motor neuropathy. MRI showed abnormal signal intensities involving the basal ganglia. Since no memory deficits were observed, we argue that the parkinsonian syndrome was caused by cyanide intoxication rather than by subcortical damage due to hypoxia.

    We hypothesized that Tabun poisoning, as well as other organophosphorous treatment, cause specific organs' oxidative changes that have not previously been substantiated investigated. In this regard, a marker for nitrosative-oxidative stress in the main haemodynamic organs (heart and kidney) could reveal the existence of such changes. In this study, for the first time we studied the nitrosative/oxidative stress in heart and kidney after acute Tabun (Ethyl N,N- Dimethylphosphoramidocyanidate) poisoning measuring by immunohistochemistry the expression of 3-nitrotyrosine--a marker for nitrosative-oxidative stress. We investigated nitrotyrozine expression in three different groups of animals (with at least 3 animals in each group): the first group was treated with 0.5 LD50 Tabun and organs were collected after 24 h; the second group received vehicle for the same period; in the third group a highly specific re-activator was applied immediately after Tabun application. Heart and kidney were collected after 24 h. The levels of nitrotyrozine production significantly increased (more than 3 times) in cardiomyocytes after Tabun. The application of re-activator slightly reduced these levels not reaching the basal heart levels. Nitrotyrozine expression in kidney increased more than 2 times after Tabun and application of re-activator did not change it significantly. In conclusion, our study evidently demonstrated that Tabun trigger oxidative-nitrosative stress in heart and kidney and these cellular effects should be protected by an additional anti-oxidant therapy, since acetylcholinesterase re-activator is not efficient in this manner.

    Two patients, a 4-year-old girl and her brother 1 1/2 year-old, with cyanide poisoning are reported. They vomited and became comatose 9 hours after ingestion of boiled cassava. At a community hospital, they were intubated and given ventilatory support. The girl was transferred to Ramathibodi Intensive Care Unit. At 19 hours after ingestion, sodium nitrite and sodium thiosulfate were given as well as other supportive treatment. She recovered with normal breathing on the next day. The boy was referred to Ramathibodi 4 hours later. On arrival, he appeared normal except for the bitter almond breathe. Only supportive treatment was given. Their blood cyanide levels on arrival were 0.56 and 0.32 microgram/ml (normal value < 0.3 microgram/ml) respectively confirming the diagnosis of cyanide poisoning. Other abnormal laboratory findings included metabolic acidosis and lactic acidemia. The pathogenesis and management of cyanide poisoning are reviewed.

    In a dairy herd of 21 cows which were on pasture during the day at the end of May 2002, four eight years old cows were suddenly inappetent and showed severe diarrhoea consisting of black discolorate feces. A few days after the onset of the disease, three affected cows exhibited neurological disorders. These cows were admitted to the IInd Medical Clinic of the University for Veterinary Medicine in Vienna. Following clinical signs were observed: circulatory weakness, anorexia, atony of the rumen, diarrhoea and in accordance with acute lead poisoning typical signs of the central nervous system. One cow died and the other two animals were euthanized. Results of blood testing were anaemia, basophil spotting of erythrocytes, increase of liver enzymes and CK, hypocalcaemia, decrease of potassium and phosphate. The cerebrospinal fluid of two cows showed increased CK-, LDH- and AST-values. The lead contents of whole blood samples were between 0.486 and 0.928 mg/kg, of liver samples 13.3 to 114.4 mg/kg, of kidney samples 172.2 to 448 mg/kg and of rumen content 59 mg/kg fresh matter. At necropsy, enteritis, liver fluke disease and severe interstitial and alveolar pulmonary emphysema were found. Pathohistologically typical ischaemic necrosis of neurons predominantly at the tips of the gyri, disseminated petechial hemorrhages and moderate diffuse neovascularisation, but no acid-fast intranucleolar inclusion bodies in the renal tubules were observed. As causative agent of the acute lead poisoning a residue on combustion, taken up by the cows on the pasture, was confirmed. The ash residue was formed by combustion of three tires which contained 450 g heavy weights of 96.5% lead for wheel balance. The lead content of the ash residue was between 2.9 and 28 g/kg dry matter.

    The 91 patients over the age of 10 (57 women and 32 men) with severe self-poisoning admitted to the ICU of a general hospital in Barcelona during the period 1974-1980 have been retrospectively studied. Previous suicidal attempts have been identified among 32 patients; 26 patients presented a history of personality disorders, and 19 had a neurological disease, a chronic physical illness, or a history of alcoholism. Sedative-hypnotic drugs were involved in about half the number of cases, and one fifth of total cases were due to tricyclic antidepressants and phenothiazines. Paracetamol was only involved in 2 cases, and heroin in another 2 cases. Many of the most severe morbidity manifestations were related to overdoses by intermediate-acting barbiturates. Two out of a total of 5 deaths were related to butalbitone overdose. Butalbitone had been ingested as a fixed-dose combination containing butalbitone, propyphenazone, and caffeine, which is freely dispensed as an analgesic in Spain.

    Since they are available in open markets and pharmacies, pesticides have been widely used all over the country. (Un)intentional poisoning with these compounds is one of the most common causes of chemical poisoning, especially in rural agricultural areas. Pesticide poisonings reported by various countries showed that it is a worldwide health problem with 250,000-370,000 associated deaths each year. In this study, medico-legal deaths between the years 2001 and 2011 in Ankara and nearby cities in Turkey were investigated retrospectively. The autopsies were partly carried out by Ankara Branch of Council of Forensic Medicine. Data were collected from reports of the Morgue Department whose toxicological analyses were performed in the Chemistry Department. The data revealed that 70 cases out of 10,720 autopsied ones had been attributed to fatal pesticide poisoning. The age range was 1-80 years (mean ± SD, 41.33 ± 17.42 years). Most of the cases (60%) were reported from Ankara. Insecticides were the most common (94%) cause of fatal pesticide poisonings, most of them (63%) being organophosphate insecticides. The percentages of pesticide-induced deaths are quite high in our society and should therefore not be underestimated. Accordingly, intensive efforts to reduce occupational and intentional pesticide poisonings are urgently needed in Ankara and nearby cities.

    Organophosphorus and carbamate compounds have largely replaced chlorinated hydrocarbons for pesticidal use in the United States, and many cases of poisoning resulting from exposure to these anticholinesterase agents have occurred in free-living birds. Although lead shot has been prohibited for waterfowl hunting throughout the United States since 1991, lead poisoning from the ingestion of spent lead shot is still occasionally seen in wild birds, and lead poisoning from the ingestion of fishing sinkers is an emerging issue of concern. A thorough history, a complete necropsy evaluation, and appropriate laboratory analysis of tissues are required to diagnose toxicoses in wild birds, including those caused by anticholinesterase compounds and lead. The interpretation of brain cholinesterase (ChE) activity results depends on the methods of analysis and comparison with expected normal enzyme activities in brain tissue from the same species. Although lead residues in tissues vary among species, many lead poisoned birds have tissue residues that are much higher than the lower threshold commonly accepted for a diagnosis of lead poisoning. We review histories, necropsy findings, and analytical methodologies and results for selected anticholinesterase and lead poisoning cases diagnosed in wild raptors, waterfowl, and loons.

  15. Toxicology in the Old Testament. Did the High Priest Alcimus die of acute aconitine poisoning?

    2002-01-01

    The Bible contains several interesting contributions to the history of neurology, as is the case of the High Priest Alkimos, who died suddenly in 159 BC. He was regarded as a stereotypical stroke victim for a long time. The reports on his death in the Septauginta and the later 'Jewish Antiquities' of Flavius Josephus present some typical symptoms of stroke (collapse, loss of speech and death within a short time), but they also describe severe pains, which are very unusual among patients with stroke. Similar symptoms can be found in the case of the Roman emperor Claudius, who was poisoned by his spouse Agrippina. It was thought that she used aconitine, an ingredient of the monkshood plant (Aconitum napellus L.), which imitates an apoplectic insult, but also causes vehement pains. It was therefore possible that something similar had happened to Alkimos, as aconitine was a common poison in ancient times and the surroundings of his death may confirm the suspicion. Reigning during a time of great upheaval, Alkimos was able to maintain his high office chiefly because of the help of the Seleucides. He has just begun construction work on the temple of Jerusalem, an order, which was regarded as a sacrilege by his foes. This impression was enhanced by his subsequent illness which could be considered as a divine punishment.

  16. Combined administration of hyperbaric oxygen and hydroxocobalamin improves cerebral metabolism after acute cyanide poisoning in rats.

    Hyperbaric oxygen therapy (HBOT) or intravenous hydroxocobalamin (OHCob) both abolish cyanide (CN)-induced surges in interstitial brain lactate and glucose concentrations. HBOT has been shown to induce a delayed increase in whole blood CN concentrations, whereas OHCob may act as an intravascular CN scavenger. Additionally, HBOT may prevent respiratory distress and restore blood pressure during CN intoxication, an effect not seen with OHCob administration. In this report, we evaluated the combined effects of HBOT and OHCob on interstitial lactate, glucose, and glycerol concentrations as well as lactate-to-pyruvate ratio in rat brain by means of microdialysis during acute CN poisoning. Anesthetized rats were allocated to three groups: 1) vehicle (1.2 ml isotonic NaCl intra-arterially); 2) potassium CN (5.4 mg/kg intra-arterially); 3) potassium CN, OHCob (100 mg/kg intra-arterially) and subsequent HBOT (284 kPa in 90 min). OHCob and HBOT significantly attenuated the acute surges in interstitial cerebral lactate, glucose, and glycerol concentrations compared with the intoxicated rats given no treatment. Furthermore, the combined treatment resulted in consistent low lactate, glucose, and glycerol concentrations, as well as in low lactate-to-pyruvate ratios compared with CN intoxicated controls. In rats receiving OHCob and HBOT, respiration improved and cyanosis disappeared, with subsequent stabilization of mean arterial blood pressure. The present findings indicate that a combined administration of OHCob and HBOT has a beneficial and persistent effect on the cerebral metabolism during CN intoxication.

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

    A case of organophosphate (OP) poisoning was admitted to the emergency room. The patient accepted treatment with pralidoxime (PAM), atropine, and supporting therapy. It was observed that even after 22 h after treatment, 960 mg of atropine was not enough for the patient to be atropinized. However, a 160-mg follow-up treatment of anisodamine was quite enough for atropinization after 4 h. As a case report, more studies are required before any definite conclusion can be reached regarding the use of anisodamine as a potential substitute for high-dose atropine in cases of OP poisoning.

    Introduction Poisoning is one of the most important health issues in the world. There is no exact statistic regarding the epidemiology of poisoning in Iran. The aim of this systematic review was to study the epidemiology of poisoning of adults in Iran. Methods All the published papers regarding the epidemiology and patterns of adult poisonings in different parts of Iran were reviewed in bibliographical databases, including SID, Iran Medex, Medlib, Magiran and Embase, Scopus, PubMed, and Google Scholar, without time limitation up to March 21, 2016. We searched for the terms poisoning, Iran, and epidemiology. After the final analysis, 38 articles that fulfilled all the required conditions were selected. Result In this article, we show that in most Iranian cities, except Ahvaz, pharmaceutical drugs, especially psychiatric pharmaceutical drugs, are the most common cause of poisoning in adults. In the Southwest region of Iran, poisoning due to envenomation is a very common. Although pesticide and opioid poisonings are less common, they are an important cause of death due to poisoning in Iran. Conclusion Pharmaceutical drugs are the most common cause of poisoning in most Iranian cities and it is recommended not to store pharmaceutical drugs at home and to set special rules regarding proper description of pharmaceutical drugs. More public health instruction is essential in the Southwest cities of Iran in order to reduce animal poisonings. PMID:27790337

    Approximately ten species of dangerously poisonous plants are found in Finland. Severe plant poisonings are very rare. Edible plants eaten raw or wrongly processed may cause severe symptoms. As first aid, activated charcoal should be given to the person who has eaten a plant causing a risk of significant poisoning. In case of exposure to topically irritating plant fluids, the exposed person's eyes must be irrigated and mouth or skin washed with copious amounts of water. In combination with solar UV radiation, light-sensitizing plants cause local burns. The diagnosis of plant poisoning is usually based on incidental information; the plant should be identified in order to make the correct treatment decisions.

    Different hospitals produce different cultures-products of relationships between people of different staff categories and people from external community groups. These relationships demonstrate unique social dynamics in rural peripheral hospitals that form a major part of the health care system in Sri Lanka and other developing countries. Understanding the existing social dynamics might be useful when trying to implement new treatment guidelines that can involve behavior change. We aimed to explore the existing social dynamics in peripheral hospitals in rural Sri Lanka by examining the treatment related to cases of acute self-poisoning that is a common, highly interactive medical emergency. These hospitals demonstrate higher levels of community influence in treatment decisions and closer interactions between hospital staff. We argue that health care teamwork is effective in peripheral hospitals, resulting in benefits to all staff, who see these hospitals as better places to work and train, in contrast to a commonly held belief that such rural hospitals are disadvantaged and difficult places.

    This study reports the case of a 44-year-old woman with oral oxalic acid poisoning. As the illness progressed, the patient exhibited severe metabolic acidosis, large-area esophageal mucosa injury and acute kidney injury, which required dialysis. A guide wire slipped out of position during the process of hemodialysis and moved back and forth in the veins, but was removed successfully by interventional endovascular treatment. However, the patient's esophageal mucosa exfoliated, which lead to severe benign esophageal stenosis and dysphagia. Balloon distention was conducted twice in the upper digestive tract using X-ray location in combination with a dumb-bell bladder and interventional wire. The patient exhibited convulsions, shock, embolism and loss of consciousness while undergoing the second balloon distention procedure. Following symptomatic treatment, the patient eventually remained in a stable condition, the digestive tract expansion procedure was not resumed and a jejunostomy was performed in order to facilitate enteral nutrition, which was administered via the jejunum and had little stimulatory effect on the pancreas. Following various treatments, the patient's condition improved markedly, with renal function returning to normal. PMID:26889241

    We describe a series of four cases of childhood lead poisoning and two cases of adult lead toxicity in a professional family exposed to lead dust and fume during renovation of a rural farmhouse. Initial blood lead levels in the children ranged from 2.70 to 4.20 microM/L (56 to 87 microns/dl) and all four required chelation therapy. Lead-based paint poisoning, a well recognized entity among young children in poor, urban neighborhoods, is not confined exclusively to such areas.

    The present study was designed to assess the usefulness of measuring plasma levels of copeptin (a peptide co-released with the hypothalamic stress hormone vasopressin) as a biomarker for the severity of carbon monoxide (CO) poisoning and for predicting delayed neurological sequelae (DNS). Seventy-two patients with CO poisoning and 72 sex and age matched healthy individuals were recruited. Plasma copeptin levels were measured on admission from CO poisoning patients and for healthy individuals at study entry by using a sandwich immunoassay. The CO poisoning patients were divided into two groups according to severity (unconscious and conscious) and occurrence of DNS. The mean plasma copeptin levels (52.5±18.5 pmol/L) in the unconscious group were significantly higher than in the conscious group (26.3±12.7 pmol/L) (P<0.001). Plasma copeptin levels of more than 39.0 pmol/L detected CO poisoning with severe neurological symptoms e.g. unconsciousness (sensitivity 84.6% and specificity 81.4%). The plasma copeptin levels were higher in patients with DNS compared to patients without DNS (52.2±20.6 pmol/L vs. 27.9±14.8 pmol/L, P<0.001). Plasma copeptin levels higher than 40.5 pmol/L predicted the development of DNS (sensitivity 77.8%, specificity 82.1%). Plasma copeptin levels were identified as an independent predictor for intoxication severity [odds ratio (OR) 1.261, 95% confidence interval (CI) 1.112-1.638, P=0.002] and DNS (OR 1.313, 95% CI 1.106-1.859, P=0.001). Thus, plasma copeptin levels independently related to intoxication severity and were identified as a novel biomarker for predicting DNS after acute CO poisoning.

    Between January 1993 and July 1996, a total of 2827 intentional cases of poisoning were registered in the University Hospitals of Leuven, Belgium. Ten of these cases were fatal. This study was set up to evaluate the substances involved, the circumstances, the features and the characteristics of the patients who died due to intentional poisoning. The male to female ratio of these fatal cases was 9 : 1. The median age was 43 years. Two groups of substances were revealed to be associated with fatal outcome. The first group consisted of chemicals (seven lethal cases): cholinesterase inhibitors ( =3), methanol ( =2) and paraquat ( =2). The second group consisted of benzodiazepines (three lethal cases). In the cases of poisoning with chemicals, death was directly related to product toxicity and the severity of the poisoning, whilst with benzodiazepines, which are considered to be relatively safe drugs even when taken in overdose, there was a clear relationship between a fatal outcome and a delay between ingestion and medical support. Product toxicity, complications and a delay in medical support may be considered as predictors for the effectiveness and efficacy of treatment and may influence which medical treatments need to be administered.

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

    The primary aimed of this study was to investigate the potential protective effects of methanolic extract of citrus peel (MECP) on acute cyanide (KCN) poisoning-induced seizures and oxidative stress in rats. The intraperitoneal LD50 value of KCN (6.3 mg/Kg bwt), based on 24 hrs mortality, was significantly increased by 9, 52 or 113% by oral administration of MECP (500 mg/Kg bwt) pre-administered for 1, 2 and 3 days, respectively, in rats in a time-dependent manner. Intraperitoneal injection of the sublethal dose of KCN (3 mg/Kg bwt) into rats increased, 24 hrs later, lipid peroxidation (LPO), nitric oxide (NO), glutamate levels and acetylcholinesterase (AChE) activity in hippocampus, striatum and cerebral cortex. KCN also decreased brain glutathione (GSH) level and superoxide dismutase (SOD) and catalase (CAT) activities in these animals. Pre-treatment of rats with MECP inhibited KCN-induced increases in LPO, NO, and glutamate levels and AChE activity as well as decreases in brain GSH level and SOD and CAT activities. In addition, KCN significantly decreased norepinephrine, dopamine and serotonin levels in different brain regions which were resolved by MECP. From the present results, it can be concluded that the neuroprotective effects of MECP against KCN-induced seizures and oxidative stress may be due to the inhibition of oxidative stress overproduction and maintenance of antioxidant defense mechanisms.

    1. Urinary metabolites from human subjects acutely poisoned with p-chloro-nitrobenzene (p-CNB) were identified by g.l.c.-mass spectrometry. 2. Eight substances, namely, a very large amount of N-acetyl-S-(4-nitrophenyl)-L-cysteine, relatively large quantities of p-chloroaniline, 2-chloro-5-nitrophenol and p-chloroformanilide produced by pyrolysis of a substance originating from p-CNB, small amounts of 2-amino-5-chlorophenol and 2,4-dichloroaniline, and traces of p-chloroacetanilide and 4-chloro-2-hydroxyacetanilide, were detected in urine samples. 3. All of the absorbed p-CNB was metabolized prior to excretion, as the parent compound was not found in urine. 4. N-Acetylated metabolites of p-chloroaniline and 2-amino-5-chlorophenol, resulting from p-CNB by metabolism, were found in only one of eight individuals indicating that this pathway is weak or may be absent in some humans. 5. A scheme for the pattern of metabolic pathways of p-CNB is proposed, and chlorination was considered to be a possible novel metabolic pathway.

    Two variants of thanatogenesis were formulated in cases of death of acute alcohol intoxication; according to the above variants, different combinations of macro- and micro signs as well as of biochemical indices of carbohydrates content in the hepatic tissues and blood are revealed during cadaver examinations. The diagnostic value of the mentioned signs demands that the thanatogenesis specific features must be taken into account in each separate case.

    Genetic polymorphisms influence the metabolism of ethanol and methanol, but the potential effects of genetic predisposition on the clinical course, outcome and short-term health sequelae of acute methanol poisoning are unknown. To evaluate the role of the MEOS system in methanol poisoning, we analysed the effect of three polymorphisms (RsaI - rs2031920; PstI - rs3813867; insertion/deletion I/D) within the CYP2E1 enzyme (MEOS system) in 50 adult survivors of methanol poisoning and compared their genotype frequencies with 460 controls. The minor allele frequencies of all three polymorphisms were below 5% in both groups. We did not detect significant differences in the genotype frequencies between survivors of methanol poisoning and controls (p = 0.34 for the RsaI variant; p = 0.59 for the PstI variant and p = 0.21 for the I/D polymorphism). The carriers of at least one minor allele in the CYP2E1 gene had less severe clinical symptoms and better short-term outcome after acute poisoning. Variants within the CYP2E1 gene are likely not significant genetic determinants of acute methanol poisoning (if survivors are analysed), but they may influence the severity of methanol poisoning and its visual/central nervous system (CNS) outcome.

    Superwarfarin poisoning is usually due to chronic occult small-dose exposures and can easily be misdiagnosed and may lead to serious complications. The diagnosis can be confirmed by a concordant history and analyses of blood and urine specimens with the liquid chromatography with tandem mass spectrometry (LC-MS/MS) technique. Several months of continuous treatment with high doses of daily oral vitamin K, as well as other supportive measures, are warranted, especially when repeated laboratory measurements to help predict the treatment period are not available. In this paper, a case of superwarfarin poisoning due to chronic repetitive occupational dermal exposure to commercial rodenticides is presented. PMID:27093901

  16. Saint Ioannis Lampadistis, the first possible case of blindness due to organic mercury poisoning in history.

    PubMed

    Saint Ioannis Lampadistis is a Cypriot saint of the Greek Orthodox Church, widely venerated in his island of origin. He lived during the 11th century and was blinded by ingesting contaminated fish in the mountainous area of Galata, withdrew from civil life when he was 18, and died at the age of 22. The reason for his blindness remains unknown, though it is widely attributed to an unknown poison related to the copper mines of the region. As fish is the end reservoir of organic mercury, it is quite possible that his blindness was the result of heavy metal toxicity. Organic mercury is associated with CNS atrophy and hypoplasia, and blindness is a frequent presenting symptom. While not much is known about the saint's clinical symptoms (as his ecclestiastical biography focuses on his example and miracles), organic mercury poisoning could explain his sudden loss of vision, thus possibly making him the first-recorded case of organic mercury poisoning in history.

    Toxic epidermal necrolysis (TEN) is a life-threatening, typically drug-induced, mucocutaneous disease. Whether paraquat, one of the most widely used herbicides, could induce TEN is not known. We describe 2 paraquat-poisoned patients with TEN. Both patients presented erythema after hospital discharge following initial paraquat poisoning and then developed a widespread eruption of diffuse erythema on almost the whole body, with bullae, epidermal necrosis and sloughing. They were successfully treated with intravenous immunoglobulin and methylprednisolone. These clinical features were consistent with TEN caused by medications with a high risk to induce Stevens-Johnson syndrome/TEN. Moreover, it is suggested that both skin exposure and ingestion of paraquat could induce TEN. To our knowledge, this is the first case report of TEN related to paraquat poisoning.

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

    Clonidine poisoning's clinical feature is well documented in the medical literature, but the minimal toxic dose has not yet been established. The effectiveness of naloxone is also controversial. The authors describe a clonidine overdose in a 9-year-old boy (25 kg) during a growth hormone test: he received tenfold the prescribed clonidine dose (0.23 mg instead of 0.023 mg) with 6.2 mg betaxolol. About 40 min later, he became drowsy and then complained of low blood pressure, bradycardia, and myosis. By maintaining the Trendelenburg position, administering fluids as well as salbutamol and naloxone (three doses of 0.2 mg were required), he recovered and was discharged from the hospital on day 2. The minimal clonidine toxic dose, the clinical picture, and the effectiveness of naloxone administration are discussed in this paper.

    Munchausen syndrome by proxy (MSBP), also known as fabricated or induced illness in a child by a caretaker, is a form of abuse where a caregiver deliberately produces or feigns illness in a person under his or her care, so that the proxy will receive medical care that gratifies the caregiver. The affected children are often hospitalized for long periods and endure repetitive, painful and expensive diagnostic attempts. We present an analytically confirmed case of MSBP by alimemazine. A 3-year-old boy was brought repetitively to a Pediatric Emergency Department by his mother because he presented limb tremors, dysarthria, obnubilation, and ataxia and generalized tonic-clonic seizures coinciding with intermittent fever. Neither the rest of the physical examination nor the complementary tests showed any significant alterations. MSBP was suspected and a routine systematic toxicological analysis in urine and blood was requested. Alimemazine was detected in all biological samples. The administration of this drug was never mentioned by the mother and the subsequent interview with her corroborated the suspicion of MSBP. Clinically, after separation from the mother, the child's neurological symptoms gradually improved until the complete disappearance of the cerebellar symptoms. Alimemazine was quantified in serum, urine, gastric content and cerebrospinal fluid samples by gas chromatography-mass spectrometry (maximum serum level was 0.42μg/ml). Hair quantification of alimemazine was performed by ultra-performance liquid chromatography-tandem mass spectrometry in different segments of hair. The results confirmed regular substance use during the at least eight last months (8.8, 14.7, 19.7 and 4.6ng/mg hair starting from most proximal segment). This patient represents the first case published with analytical data of alimemazine in blood, urine, gastric content, cerebrospinal fluid and hair, which allowed us to prove an acute and repetitive poisoning with alimemazine as evidence

    Lead (Pb) poisoning of cattle has been relatively common in Australia and sump oil has been identified as an important cause of Pb toxicity for cattle because they seem to have a tendency to drink it. Lead-free petrol has been available in Australia since 1975, so the aim of this study was to assess the current risk to cattle from drinking used automotive oils. Sump or gear box oil was collected from 56 vehicles being serviced. The low levels of Pb found suggest that the removal of leaded petrol from the Australian market as a public health measure has benefited cattle by eliminating the risk of acute poisoning from used engine oil.

    We encountered a patient in a restless excitable state after eating boiled jimson weed grown in the patient's garden. The patient mistook the weed for Angelica keiskei. Pupillary dilation (7/7mm), weak light reflex, body temperature of 37 degrees C, respiratory frequency of 19/min, blood pressure of 138/88 mmHg, pulse rate of 108/min, and hot feeling were observed. No abnormalities nor special findings were detected by general examination of the peripheral blood, biochemical examination of the blood, general examination of the urine, or electrocardiography. Atropine and scopolamine, which are tropane alkaloids, were detected by the GC/MS. The retention time of atropine-TMS was 17.0 min, and the mass spectra were m/z 124, 82, and 140. The retention time of scopolamine-TMS was 17.7 min, and the mass spectra were m/z 138, 108, 154 and 375. At the time of consultation, the serum concentrations of atropine and scopolamine were 31.3 ng/ml, and 30.6 ng/ml, respectively, and decreased to 6.7 ng/ml and 8.5 ng/ml, respectively, after 2 hours. The patient underwent injection of activated carbon after gastrolavage with 2,000 ml warm water, and neostigmine was administered. The patient awoke the following morning, and was discharged with mild pupillary dilation 2 days after poisoning.

    The aim of this article was to study the role of serum formate (S-formate) in diagnosing methanol poisoning. A prospective study was undertaken of 38 patients from the Czech methanol mass poisoning in 2012 - median age 51 [interquartile range (IQR) 37-62] years with confirmed methanol poisoning. S-formate was measured enzymatically. The receiver operating characteristics (ROC) curve was used to examine the predictive ability of S-formate. Asymptomatic patients had median S-formate of 1.9 (IQR 1.5-2.4) mmol/L. The median S-formate was 15.2 (IQR 13.9-17.6) mmol/L in symptomatic subjects with visual disturbances, 15.4 (12.1-18.0) mmol/L in subjects with dyspnoea and 15.7 (IQR 12.8-18.5) mmol/L in comatose patients. The differences in serum formate concentrations in symptomatic patients depending on clinical features were not significant (all p > 0.05). Patients with long-term visual sequelae of poisoning had median S-formate of 16.1 (IQR 14.3-19.9) mmol/L; with central nervous system (CNS) sequelae, patients had 15.9 (IQR 14.2-19.5) mmol/L. In lethal cases, the median S-formate was 15.2 (IQR 13.8-15.9) mmol/L. The probability of a poor outcome (death or survival with sequelae) was higher than 90% in patients with S-formate ≥17.5 mmol/L, S-lactate ≥7.0 mmol/L and/or pH <6.87. The ROC analysis showed that the corresponding areas under the curve (AUC) were 0.64 (0.44-0.85 CI 95%) for S-formate, 0.75 (0.56-0.93 CI 95%) for 'S-formate+S-lactate' and only 0.54 (0.38-0.69 CI 95%) for serum methanol, which is lower than for S-formate (p < 0.05). The measurement of S-formate is an important tool in the laboratory diagnostics and clinical management of acute methanol poisoning. S-formate ≥3.7 mmol/L can lead to the first clinical signs of visual toxicity, indicating haemodialysis. S-formate ≥11-12 mmol/L is associated with visual/CNS sequelae and a lethal outcome.

    The case of a 55-year-old man who attempted suicide by ingesting <100 mL of 28% sodium chlorite solution is presented. On arrival in the intensive care unit, the patient appeared cyanotic with lowered consciousness and displayed anuria and chocolate brown serum.Initial laboratory tests revealed 40% of methemoglobin. The formation of methemoglobin was effectively treated with methylene blue (10% after 29 hours).To remove the toxin, and because of the anuric acute renal failure, the patient received renal replacement therapy. Despite these therapeutic measures, the patient developed hemolytic anemia and disseminated intravascular coagulation, which were treated with red blood cell transfusion and intermittent hemodialysis. These interventions led to the improvement of his condition and the patient eventually fully recovered. Patient gave written informed consent.This is the third known case of chlorite poisoning that has been reported. Based upon this case, we suggest the management of sodium chlorite poisoning to comprise the early administration of methylene blue, in addition to renal replacement therapy and transfusion of red blood cells.

    Accidental self-poisoning or deliberate use in suicidal intent of organophosphorus pesticides (OPP), which are widely used in agriculture, represent a health problem worldwide. Symptoms of poisoning are characterized by acute cholinergic crisis caused by inhibition of acetylcholinesterase. A 75-year-old male patient ingested 20ml of an OPP solution containing 10% methamidophos in suicidal intent. In the course of poisoning typical clinical symptoms of cholinergic crisis (miosis, bradycardia, hypotension, hypersalivation and impairment of neurologic status) were evident. Butyryl (plasma) cholinesterase (BChE) and red blood cell acetylcholinesterase (RBC-AChE) revealed decreased activities, thus specific treatment with the enzyme reactivator obidoxime was started. Inhibitory activity of the patient's plasma indicated significant amounts of persisting methamidophos in the circulation and was still found on day 4 after ingestion. Due to missing spontaneous breathing on day 6, obidoxime was administered again. Afterwards a significant increase of RBC-AChE activity was found. The patient was extubated on day 10 and a restitution ad integrum was achieved. In conclusion, obidoxime is a potent reactivator of OPP-inhibited AChE. A repetitive and prolonged administration of obidoxime should be considered in cases of severe methamidophos poisoning and should be tailored with an advanced analytical biomonitoring.

    A retrospective analysis of telephone enquiries to the Veterinary Poisons Information Service found 772 cases with follow-up concerning suspected metaldehyde slug bait ingestion in dogs between 1985 and 2010. Half the enquiries occurred in the summer months. The amount and strength of the slug bait ingested was rarely known. In 56, cases the quantity consumed was estimated and was on average 229.6 grams of bait. Clinical signs developed in 77.3 per cent of dogs; common signs were convulsions, hypersalivation, twitching, hyperaesthesia, tremor, vomiting, hyperthermia and ataxia. Only 4.6 per cent of dogs developed hepatic changes, and only one developed renal impairment. The average time to onset of signs was 2.9 hours post-ingestion, with 50.3 per cent of dogs developing effects within one hour. Increased muscle activity (twitching, convulsions) lasted on average 15.2 hours. Recovery time was reported in 61 cases and occurred on average at 39.3 hours. Common treatments were gut decontamination, anticonvulsants, anaesthetics and intravenous fluids. Of the dogs that were treated with sedatives, 45.8 per cent required more than one sedative or anaesthetic agent. Methocarbamol was rarely used, probably due to unavailability. The outcome was reported in 762 dogs; 21.7 per cent remained asymptomatic, 61.7 per cent recovered and 16 per cent of dogs died or were euthanased. Where known (only six cases), the fatal dose of bait ranged from 4.2 to 26.7 g/kg (average 11.8 g/kg).

    Aluminum phosphide (AlP) is a solid fumigant which is widely used for a suicide attempt in Iran. Although neurologic symptoms are commonly reported, cerebrovascular stenosis is rare in AlP poisoning. We described ischemic stroke as a delayed complication of AlP intoxication. A 30-year-old man was admitted because of sudden onset left side hemiplegia, 11 days after intentional ingestion of three rice tablets. Investigations revealed in situ thrombosis in right middle cerebral artery (MCA) while other causes of stroke in young adults were excluded. Ischemic stroke should be considered as a delayed complication of AlP intoxication even after the acute phase of intoxication.

    Acute hepatitis E is an endemic disease, commonly reported in Indian subcontinent, China, Africa, Central America, and so forth. It is a self-limiting disease like other acute hepatitis except in pregnant patient. Although sporadic hepatitis E is noted all over the world, most of them are associated with travel history to HEV-endemic area. In Korea, Hepatitis E is rarely reported. Moreover, sporadic acute hepatitis E without travel history to HEV-endemic area is very rare. We experienced three sporadic cases of acute hepatitis E, without travel history. All of them presented acute hepatitis symptoms, elevated aminotransferase, and positive IgM HEV Ab. Symptoms and aminotransferase levels were normalized during hospitalization and IgM HEV Ab converted negative after 4-8 months. We report three sporadic cases of onset-acute hepatitis E without travel history to HEV-endemic area.

    Aluminum phosphide is one of the commonest poisons encountered in agricultural areas, and manner of death in the victims is often suicidal and rarely homicidal or accidental. This paper presents an unusual case, where two humans (owner and housemaid) and eight dogs were found dead in the morning hours inside a room of a house, used as shelter for stray dogs. There was allegation by the son of the owner that his father had been killed. Crime scene visit by forensic pathologists helped to collect vital evidence. Autopsies of both the human victims and the dogs were conducted. Toxicological analysis of viscera, vomitus, leftover food, and chemical container at the crime scene tested positive for aluminum phosphide. The cause of death in both humans and dogs was aluminum phosphide poisoning. Investigation by police and the forensic approach to the case helped in ascertaining the manner of death, which was accidental.

    Domestic kitchen food handling risk factors for sporadic salmonella food poisoning are largely unknown. We compared food consumption and food handling practices, opportunities for cross contamination and refrigerator temperature control, in 99 households in South East Wales in 1997/8 with a case of salmonella food poisoning, and control households matched for electoral ward. On univariate analyses, cases were significantly more likely than control respondents to have purchased free-range eggs in the preceding week, and more likely than control households to have handled frozen whole chicken in the previous week, and to handle raw chicken portions at least weekly. In multivariate analysis, only consumption of raw eggs and handling free-range eggs were significant risk factors, independent of the age structure of the family and of the season.

    The study included 147 patients with toxico-hypoxic encephalopathy resulting from acute poisoning. It was shown that intensive therapy with cytoflavin (20 ml in 400 ml of 5% glucose solution twice daily for 7 days) reduced severity of hypoxic brain lesions and suppression of CNS as apparent from the improvement of its bioelectric activity. The recovery of CNS regulatory action on the life-sustaining systems of the body promoted normalization of the respiratory component of oxygen transport. The improvement of the patients' conditions in the acute phase contributed to accelerated recovery of cognitive-amnestic functions and social adaptation. Cytoflavin therapy improved the clinical picture of toxico-hypoxic encephalopathy due to the reduction in the duration of the comatose state from 45.3 +/- 8.2 to 27.7 +/- 6.9 hr and the decrease in the frequency of secondary pulmonary complications from 72.7 to 35.9%.

    Many conditions affect the salivary glands. Acute sialadenitis is infectious or inflammatory disorders of the salivary glands. The exact frequency of submandibular sialadenitis is unclear. The acute conditions more typically involve the parotid and submandibular glands. During an acute inflammatory process, there is swelling of the affected gland, overlying pain, gland tenderness, fever, and on occasion difficulty in opening the mouth. Initial treatment should include rehydration oral antistaphylococcal antibiotic should be started while awaiting culture results. Hygiene and repeated massaging of the gland when tenderness had subsided. The present report describes a case of acute submandibular sialadenitis in a 70-year-old female. PMID:22888457

    Acute carbon dioxide (CO2) poisoning causes no specific features that are revealed upon autopsy, and the pathophysiological mechanism of this syndrome is unclear. To address this issue, in the present study, we exposed rats to CO2 concentrations ranging from 10% to 60% and determined the effects on mRNA expression. According to the results of Gene Ontology (GO) and cluster analyses of microarrays data, we selected the following genes for further analysis: alkylglycerone phosphate synthase (Agps), hypocretin (Hcrt), tyrosine hydroxylase (Th), heat shock protein beta 2 (Hspb2), and opioid receptor delta 1 (Oprd1) expressed in the frontal cortex and renin (Ren), pancreatic polypeptide (Ppy), corticotropin releasing hormone receptor 2 (Crhr2), carbonic anhydrase 1 (Car1), and hypocretin receptor 1 (Hcrtr1) expressed in the hypothalamus. We found significant differences between the expression levels of Agps and Hspb2 mRNAs in the frontal cortex and that of Ppy, Crhr2 mRNAs in the hypothalamus in the presence of high concentrations of CO2. Further investigation of these genes may clarify the pathophysiology of acute CO2 poisoning and facilitate the development of novel forensic tests that can diagnose the cause of death.

    Motor neuron hyperexcitability (MNH) indicates a disorder characterized by an ectopic motor nerve discharge on electromyogram (EMG). Here, we present a series of three cases of subacute MNH with mercury poisoning. The first case showed hyperhidrosis, insomnia, generalied myokymia, cramps, tremor, weight loss, and myokymic and neuromyotonic discharges, followed by encephalopathy with confusion, hallucinations, and memory decrease. The second case was similar to the former but without encephalopathic features. The third case showed widespread fasciculation, fatigue, insomnia, weight loss, and autonomic dysfunction, including constipation, micturition difficulty, and impotence, with multiple fibrillation, unstable fasciculation, widened motor neuron potential, and an incremental response at high-rate stimulation in repetitive nerve stimulation. Based on the symptoms, the three cases were diagnosed as Morvan's syndrome, Isaacs' syndrome, and Lambert-Eaton myasthenic syndrome with ALS-like syndrome, respectively. Mercury poisoning in the three cases was confirmed by analysis of blood and urine samples. All cases recovered several months after chelation therapy and were in good condition at follow-up. Very few cases of MNH linked with mercury exposure have been reported in the literature. The mechanism of mercury-induced MNH may be associated with ion channel dysfunction.

    Objective Despite the rapid industrialisation and urbanisation over the past 30 years, agriculture is one of the largest economic sectors in China and the unregulated use of pesticides result in extensive pesticide poisoning. The objective of this study was to analyse pesticide poisoning cases registration received by Zhejiang Provincial Center for Disease Control and Prevention, China. Design Register-based study. Setting Cases registered regarding pesticide poisoning. Data were obtained from the Occupational Disease Surveillance and Reporting Systems in Zhejiang province from 2006 to 2010, which contains anonymous records representing general population of Zhejiang province, China. Participants All cases registered as pesticide poisoning were identified. Primary outcome Monthly and age-group pesticide poisoning death rates were calculated. Results A total of 20 097 pesticide poisoning cases with 1413 deaths were recorded during the study period. There were 10 513 male pesticide poisoning cases with 782 deaths, and 9584 females with 631 deaths. Pesticide poisoning occurred mostly in non-occupational exposure (79.86%), in which the majority (85.77%) of the cases was of intentional pesticide poisoning. The occupational exposure was most common in men during the farming season. The death rate increased stepwise with age, and the pesticide suicide rate was higher in the older age group. Conclusions Pesticide poisoning remains a major health problem in China, and further recommendations to reduce the pesticide poisoning are required. PMID:24270833

    Sodium 3,5,6-trichloropyridin-2-ol (STCP) is an important intermediate for synthesizing organophosphate insecticide chlorpyrifos. At present, chlorpyrifos is one of the world's largest species of pesticide products. Many studies have focused on the toxicity of chlorpyrifos, but few reports have looked at the toxicity mechanism of STCP. Even fewer studies have looked at STCP poisoning. With increasing production and usage of STCP, the chances of such poisoning will increase. In this study, we present a report on four workers who helped in the industrial manufacture of STCP and who were affected by exposure to it. We hope that these case studies will provide a foundation for further research into STCP.

    A literature review performed by the EXtracorporeal TReatments In Poisoning (EXTRIP) workgroup highlighted deficiencies in the existing literature, especially the reporting of case studies. Although general reporting guidelines exist for case studies, there are none in the specific field of extracorporeal treatments in toxicology. Our goal was to construct and propose a checklist that systematically outlines the minimum essential items to be reported in a case study of poisoned patients undergoing extracorporeal treatments. Through a modified two-round Delphi technique, panelists (mostly chosen from the EXTRIP workgroup) were asked to vote on the pertinence of a set of items to identify those considered minimally essential for reporting complete and accurate case reports. Furthermore, independent raters validated the clarity of each selected items between each round of voting. All case reports containing data on extracorporeal treatments in poisoning published in Medline in 2011 were reviewed during the external validation rounds. Twenty-one panelists (20 from the EXTRIP workgroup and an invited expert on pharmacology reporting guidelines) participated in the modified Delphi technique. This group included journal editors and experts in nephrology, clinical toxicology, critical care medicine, emergency medicine, and clinical pharmacology. Three independent raters participated in the validation rounds. Panelists voted on a total of 144 items in the first round and 137 items in the second round, with response rates of 96.3% and 98.3%, respectively. Twenty case reports were evaluated at each validation round and the independent raters' response rate was 99.6% and 98.8% per validation round. The final checklist consists of 114 items considered essential for case study reporting. This methodology of alternate voting and external validation rounds was useful in developing the first reporting guideline for case studies in the field of extracorporeal treatments in poisoning

    Diabetic ketoacidosis in children causes serious morbidity and mortality, especially if it is not recognized on time in the initial diagnosis. However, there are other diseases that can appear to be a metabolic disorder of this kind and be ignored if it is not suspected. We present a clinical case with hyperglycemic ketoacidosis due to the contact with organophosphate; we had to use a continuous infusion of insulin to control the metabolic disorder without repercussions after the girl came home.

    Arsenic poisoning is one of the more important causes of heavy metal poisoning in domestic animals. Two species--dogs and cattle--are intoxicated more frequently than other animals; yet sporadic instances of poisoning have been observed in cats, horses, and pigs. Cases observed by veterinary clinicians are either peracute, acute, or chronic intoxications. Frequently the initial and only indication that a severe problem exists with peracute poisoning in a cattle herd is dead animals. Chronic intoxications are also observed in cattle. Acute intoxication is the most common form of arsenic poisoning observed and documented in the dog. Also intoxicated dogs were younger, i.e., 2-6 months of age. Arsenic is a severe alimentary tract irritant in domestic animals, and treatment in most instances consists mainly of symptomatic and supportive treatment. The source of intoxication, when it can be determined, is usually dips, sprays, powders, or vegetation contaminated by pesticides containing arsenic. PMID:908297

    Tolperisone (Mydocalm) is a centrally acting muscle relaxant with few sedative side effects that is used for the treatment of chronic pain conditions. We describe three cases of suicidal tolperisone poisoning in three healthy young subjects in the years 2006, 2008 and 2009. In all cases, macroscopic and microscopic autopsy findings did not reveal the cause of death. Systematic toxicological analysis (STA) including immunological tests, screening for volatile substances and blood, urine and gastric content screening by GC-MS and HPLC-DAD demonstrated the presence of tolperisone in all cases. In addition to tolperisone, only the analgesics paracetamol (acetaminophen), ibuprofen and naproxen could be detected. The blood ethanol concentrations were all lower than 0.10 g/kg. Tolperisone was extracted by liquid-liquid extraction using n-chlorobutane as the extraction solvent. The quantification was performed by GC-NPD analysis of blood, urine and gastric content. Tolperisone concentrations of 7.0 mg/l, 14 mg/l and 19 mg/l were found in the blood of the deceased. In the absence of other autopsy findings, the deaths in these three cases were finally explained as a result of lethal tolperisone ingestion. To the best of our knowledge, these three cases are the first reported cases of suicidal tolperisone poisonings.

    Mercury is an extremely toxic heavy metal that can devastate central nervous system. We present the case of a 15 year old adolescent with mercury intoxication following 4 days of exposure to elemental mercury at home who was consulted by department of pediatrics with complaints of demonstrated emotional lability, memory impairment, disinhibition, and impulsivity. Olanzapin 2,5 mg/day was initiated. Her neuropsychological performance was evaluated by a neuropsychological test battery at initial examination. Deterioration in neuropsychological functions like interference effect and attention (Stroop Test TBAG form), verbal fluency and switching to other category (Verbal Fluency Test, /(VFT), verbal short term and long term memory and recognition (Auditory Verbal Learning Test, /(AVLT) was detected. In 9 months follow up period her complaints resolved. Initial neuropsychological deficits were also fully recovered at follow up. There was an increase in intelligence scores with increased ability to pay and sustain attention. She had better performance at Stroop Test TBAG form, VFT and AVLT which was similar to her normal peers. In this case report, the clinical aspects of central nervous system involvement in mercury intoxication and protection from potential toxic effects of laboratory materials like mercury at schools were discussed. School administrators should be aware of and parents and students should be given necessary protective information.

    Podostroma cornu-damae is a rare, deadly fungus. However, it can be easily mistaken for antler Ganoderma lucidum. In this case report, two patients made tea with the fungus and drank it over a 2-week period. Both patients presented with bicytopenia, and one patient had desquamation of the palms and soles. Both were treated with prophylactic antibiotics and granulocyte colony-stimulating factor. One patient was admitted to the intensive care unit and received a platelet transfusion. Both patients were discharged without complications. Podostroma cornu-damae infections caused by intoxication were successfully treated using our treatment strategy, which consisted of prophylactic antibiotics, platelet transfusion, and granulocyte colony-stimulating factor. We believe this report can guide future treatment. PMID:27752639

    OBJECTIVES: To investigate an unusual outbreak of tetrodotoxin poisoning in Leizhou, southeast China, a case series analysis was conducted to identify the source of illness. METHODS: A total of 22 individuals experienced symptoms of poisoning, including tongue numbness, dizziness, nausea and limb numbness and weakness. Two toxic species, Amoya caninus and Yongeichthys nebulosus, were morphologically identified from the batches of gobies consumed by the patients. Tetrodotoxin levels in the blood and Goby fish samples were detected using liquid chromatography-tandem mass spectrometry. RESULTS: The tetrodotoxin levels in the remaining cooked Goby fish were determined to be 2090.12 µg/kg. For Amoya caninus, the toxicity levels were 1858.29 µg/kg in the muscle and 1997.19 µg/kg in the viscera and for Yongeichthys nebulosus, they were 2783.00 µg/kg in the muscle and 2966.21 µg/kg in the viscera. CONCLUSION: This outbreak demonstrates an underestimation of the risk of Goby fish poisoning. Furthermore, the relationships among the toxic species, climates and marine algae present should be clarified in the future. PMID:25672425

    2002-01-01

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

    Law-evading herbs may induce poisoning symptoms, especially when they contain synthetic cannabinoids. However, their detailed pharmacological effects have not yet been clarified. Some reports have previously described symptoms of poisoning, but only a few reports have so far described shock and myocardial damage (MD). We experienced a case of shock and MD in a patient who had smoked law-evading herbs. A 61-year-old male presented at an emergency department 8 hours after smoking law-evading herbs (Rush Trip, High Men Monster) with chest pain. A vasopressor agent was administered to treat shock and antiarrhythmic drugs were administered due to ventricular arrhythmia. The contents of the law-evading herbs were unknown, so an in-hospital follow-up was conducted to treat the patient's symptoms. The follow-up blood test showed an increased level of cardiac enzymes, which thereafter demonstrated a spontaneous remission. The systemic conditions tended to improve and the patient was discharged from the hospital on the 5th hospital day. The contents of the law-evading herbs in question were thereafter,analyzed, and synthetic cannabinoids (JWH-210, JWH-081 and JWH-122) as well as caffeine were detected. The cause for the poisoning symptoms were suspected to be the presence of synthetic cannabinoids and caffeine. Such law-evading herbs may contain synthetic cannabinoids and caffeine which both may induce shock and MD.

    We report the case of a 16 years old female patient, with a pregnancy history of 11.4 weeks by ultrasound and intrauterine fetal death. In a private clinic were prescribed methotrexate 500 mg intramuscular single dose, and vaginal misoprostol. She had a clinical feature of five days of evolution characterized by fever of 39 degrees C, nausea, general attack and vomiting. The initial diagnosis was severe sepsis secondary to septic abortion, oral candidiasis and acute poisoning by methotrexate. After that, she was referred to the Instituto Nacional de Perinatologia, where stayed with fever for four days, and was managed with hydration, antibiotics, folinic acid and alkalizing. Her recovery was gradual. She was discharged after 12 days with significant clinical improvement. The literature review describes that the use of methotrexate for abortion purpose with therapeutic-dose presents a similar adverse effects to those found in our patient, however there are no case reports that describe the use of this drug in macrodosis for the same purpose, and their cytotoxic effects. We present this case because the patient used a macrodosis of this antimetabolite and due to the premature and empirical management with folinic acid, joined with alkalinization of urine, is the ideal treatment and as it is illustrated in our case.

    In recent years, there has been increasing interest in the role of intravenous lipid formulations as potential antidotes in patients with severe cardiotoxicity caused by drug toxicity. The aim of this study was to conduct a comprehensive bibliometric analysis of all human and animal studies featuring lipid emulsion as an antidote for the treatment of acute poisoning. The Scopus database search was performed on 5 February 2016 to analyse the research output related to intravenous lipid emulsion as an antidote for the treatment of acute poisoning. Research indicators used for analysis included total number of articles, date (year) of publication, total citations, value of the h-index, document types, countries of publication, journal names, collaboration patterns and institutions. A total of 594 articles were retrieved from Scopus database for the period of 1955-2015. The percentage share of global intravenous lipid emulsion research output showed that research output was 85.86% in 2006-2015 with yearly average growth in this field of 51 articles per year. The USA, United Kingdom (UK), France, Canada, New Zealand, Germany, Australia, China, Turkey and Japan accounted for 449 (75.6%) of all the publications. The total number of citations for all documents was 9,333, with an average of 15.7 citations per document. The h-index of the retrieved documents for lipid emulsion research as antidote for the treatment of acute poisoning was 49. The USA and the UK achieved the highest h-indices, 34 and 14, respectively. New Zealand produced the greatest number of documents with international collaboration (51.9%) followed by Australia (50%) and Canada (41.4%) out of the total number of publications for each country. In summary, we found an increase in the number of publications in the field of lipid emulsion after 2006. The results of this study demonstrate that the majority of publications in the field of lipid emulsion were published by high-income countries. Researchers from

    Pentachlorophenol (PCP) is a pesticide commonly used as a wood preservative. Although exposure has been well controlled in large chemical manufacturing plants, over-exposures have recently becomes a concern at smaller facilities. Five cases of PCP poisoning, including two fatalities, occurred in two small wood preservative plants. All cases presented with fever, including severe hyperpyrexia in two; an increased anion gap and renal insufficiency were noted in two others. PCP may uncouple oxidative phosphorylation, resulting in a poisoning syndrome characterized by hyperpyrexia, diaphoresis, tachycardia, tachypnea, abdominal pain, nausea, and even death.

    We report 2 cases of teenagers who were poisoned with Jimson weed (Datura stramonium) and presented to the emergency department with a severe acute anticholinergic toxidrome after ingestion of several hundred seeds. The patients presented with visual hallucinations, disorientation, incomprehensible and nonsensical speech, and dilated sluggish pupils. Both patients required restraints for combativeness until adequate sedation with lorazepam and haloperidol was achieved. Jimson weed is found in southern Canada and the United States and can cause acute anticholinergic poisoning and death in humans and animals. The treatment of choice for anticholinergic poisoning is mainly supportive care and gastrointestinal decontamination with activated charcoal. Jimson weed intoxication should be considered in cases of patients presenting with unexplained peripheral and central anticholinergic symptoms including delirium, agitation and seizures, especially among younger patients and partygoers. It is important that health care professionals recognize that Jimson weed is a toxic, indigenous, "wild" growing plant, subject to misuse and potentially serious intoxication requiring hospitalization.

    Intoxications due to organophosphate insecticides are common in our country, since agriculture has an important place. Besides the well known acute cholinergic toxicity, these compounds may cause late-onset distal polyneuropathy occurring two to three weeks after the acute exposure. An eight-year-old boy and a 13-year-old girl admitted to the hospital with gait disturbances. Beginning 15 and 20 days, respectively, after organophosphate ingestion. Neurologic examination revealed bilateral dropped foot, absent Achilles tendon reflexes and peripheral sensory loss. Electromyography demonstrated motor weighed sensory-motor polyneuropathy with axonal degeneration significant in the distal parts of bilateral lower extremities. Biochemical, radiological findings and magnetic resonance imagings were normal. The two cases were taken under a physiotherapy program. The two cases are presented here since organophosphate poisonings are common in our country, and since late-onset polyneuropathy is not a well known clinical presentation as acute toxicity.

    Five adults were treated successfully for severe theophylline poisoning due to intentional overdosage. Clinical features included nausea, tremor, delirium, hypotension and cardiac arrhythmias, metabolic acidosis, hyperglycemia, hypokalemia and hypophosphatemia. No seizures or deaths occurred despite very high serum theophylline concentrations (between 96 and 194 μg per ml). Extreme elevations of plasma catecholamines were documented and are implicated in the toxicity. β-Blockade with intravenous administration of propranolol hydrochloride was the most effective therapy for theophylline-induced hypotension. All patients were treated with resin hemoperfusion, which resulted in significant clinical improvement and rapid lowering of the serum theophylline level. PMID:6506685

    Datura poisonings have been previously described but remain rare in forensic practice. Here, we present a homicide case involving Datura poisoning, which occurred during a robbery. Toxicological results were obtained by second autopsy performed after one previous autopsy and full body embalmment. A 35-year-old man presented with severe stomach and digestive pain, became unconscious and ultimately died during a trip in Asia. A first autopsy conducted in Asia revealed no trauma, intoxication or pathology. The corpse was embalmed with methanol/formalin. A second autopsy was performed in France, and toxicology samples were collected. Scopolamine, atropine, and hyoscyamine were found in the vitreous humor, in addition to methanol. Police investigators questioned the local travel guide, who admitted to having added Datura to a drink to stun and rob his victim. The victim's death was attributed to disordered heart rhythm due to severe anticholinergic syndrome following fatal Datura intoxication. This is a recent case of a rare homicide involving Datura that highlights general information on Datura and discusses forensic interpretation after a previous autopsy and body embalmment.

    BACKGROUND Previous reports suggest that homoplantaginin, one of the compounds isolated from Salvia plebeia, has a protective and therapeutic effect on hepatocyte injury. We present a case of serious liver and kidney damage due to incorrect use of Salvia plebeia in a patient with a history of thyroid tumorectomy, who was successfully treated for poisoning with blood purification and systemic, comprehensive critical care. CASE REPORT A 54-year-old female patient with salvia intoxication combined with multiple organ dysfunction was transported to our emergency center by ambulance after presenting with nausea, vomiting, and skin yellowing. On arrival, she exhibited fatigue, dizziness, lightheadedness, yellowish discoloration of her skin, breathing difficulties, and low back pain, all of which was suggestive of salvia intoxication combined with multiple organ dysfunction. The treatment strategy was to immediately speed up the excretion of toxins and administered blood purification therapy. She also displayed disseminated intravascular coagulation (DIC), which was successfully treated with plasma infusion of blood coagulation factor combined with LMWH acupuncture therapy. CONCLUSIONS Salvia plebeia should only be considered for use in patients who have infectious disease or oxidative stress related disease and only at an appropriate dose. In addition, for patients with salvia poisoning, prompt administration of blood purification therapy and systemic comprehensive measures involving multiple supportive therapies can save such patients.

    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.

    This study examined the effects of Y-27632, a selective Rho-kinase inhibitor, on organophosphate-induced acute toxicity in rats. Rats were randomly divided into four groups as control (corn oil), dichlorvos (30 mg kg(-1) i.p.), 1 and 10 mg kg(-1) Y-27632 + dichlorvos groups. Cholinergic signs (fatigue, tremor, cyanosis, hyper-secretion, fasciculations) were observed in all the rats in the dichlorvos group and the mortality rate was 50%. No cholinergic findings and deaths were observed in the control and Y-27632 groups. Plasma cholinesterase activities were suppressed with dichlorvos and these reductions were attenuated with Y-27632 pretreatment. There was a marked increase in plasma malondialdehyde level in the dichlorvos group, but Y-27632 pretreatment abolished this elevation. Dichlorvos markedly depressed cardiac paraoxonase activity, but these changes were not markedly modified with Y-27632. Total antioxidant capacities, total oxidant status, oxidative stress index, total free sulfhydryl groups and catalase activities in plasma and cardiac tissues were not markedly different between the groups. No significant changes were observed with cardiac myeloperoxidase activities or plasma arylesterase and ceruloplasmin activities. In conclusion, our results suggest that Rho-kinase pathway is involved in organophosphate intoxication, and a decrease in cardiac paraoxonase activities may play a role in the pathogenesis of acute organophosphate poisoning in rats.

    There is no report on the effects of sustained low-efficiency dialysis (SLED) plus hemoperfusion (HP) (SLED + HP) in patients with acute severe organophosphate (OP) poisoning (ASOPP). This study was designed to compare the therapeutic effectiveness between SLED + HP and continuous hemofiltration (CHF) plus HP (CHF + HP) in patients with ASOPP. In order to assess the two treatment methods, 56 patients with ASOPP were divided into CHF + HP group and SLED + HP group. The biochemical indicators, in-hospital duration, hemodynamic parameters, Acute Physiology, and Chronic Health Evaluation (APACHE II) score, and survival and mortality rates were compared. In both groups after treatment, the levels of serum creatine kinase isozyme MB, creatine kinase, creatinine, glutamic-oxalacetic transaminease, and glutamate-pyruvate transaminase, and the APACHE II scores on the first, second, and seventh day decreased (P < 0.05), whereas the levels of serum acetylcholinesterase increased. The two groups showed no statistical differences in in-hospital duration, biochemical indicators, APACHE II score, hemodynamic parameters, survival rate, or the mortality rate (P > 0.05). In conclusion, SLED has similar hemodynamic stability to CHF and the two treatment methods have similar effects on ASOPP patients. More importantly, SLED plus HP is relatively economical and convenient for patients with ASOPP in clinical practice.

    Cyanide is a toxic compound which inhibits the cellular utilization of oxygen. A number of substances can give rise to cyanide intoxication, which in some cases may have a delayed onset. The symptoms are non-specific and reflect cellular hypoxia. Several strategies may be employed in the treatment. Hydroxycobalamine is an effective and non-toxic antidote. On the basis of a case story, the toxicology, symptoms and treatment of cyanide poisoning are discussed.

    We report a case of sudden death due to n-butane poisoning after the inhalation of anti-perspiration aerosol deodorant. The deceased was a 15-year-old boy who was found unresponsive on the road, and was pronounced dead after 1.25h. A spray can of anti-perspiration deodorant and vinyl bags were found in a thicket near the scene. An autopsy revealed pulmonary edema, cerebral edema and congestion of the organs. Using qualitative gas chromatography/mass spectrometry, the existence of n-butane was ascertained. The concentration of n-butane (in microl/ml or microl/g) was estimated to be 15.3 in the blood, 13.3 in the brain, 26.6 in the liver, 7.5 in the lung, and 13.6 in the kidney. These n-butane levels in the blood and in the tissues were higher than those of previous reports of death associated with n-butane inhalation. We concluded that the cause of death was n-butane poisoning and presumed that n-butane in the can of anti-perspiration aerosol deodorant induced fatal cardiac arrhythmia.

    An unusual death caused by carbon monoxide poisoning after the detonation of explosives in an underground mine was investigated by the Office of the Medical Investigator of the State of New Mexico. The 50-year-old miner had 18 years of mining experience but no documented safety training. He collapsed approximately 20 minutes after entering the mine and working at the bottom of the single vertical shaft. The tight confines of the mine shaft hindered rescue personnel from reaching him, and the body was not recovered until 2 days later. The autopsy showed severe coronary artery atherosclerosis with remote and resolving myocardial microinfarcts, as well as the characteristic pink lividity of carbon monoxide poisoning, which was confirmed by laboratory analysis. Detailed investigation of the scene revealed no sources of carbon monoxide other than the explosives. The case represents an uncommon cause of death in mining that may have been avoided through the use of proper safety procedures, and illustrates the importance of recognizing the many sources of carbon monoxide.

  6. Acute and chronic methyl mercury poisoning impairs rat adrenal and testicular function

    Animals poisoned with methyl mercury (CH/sub 3/Hg) exhibit stress intolerance and decreased sexual activity, which suggest both adrenal and testicular dysfunction. Adrenal and testicular function was studied in male rats after treatment with CH/sub 3/Hg. In animals treated chronically, the adrenal glands were markedly hyperplastic with enlargement of the zona fasciculata. The mean basal serum levels of corticosterone were similar in experimental (17.8 ..mu..g/dl) and control (16.8 ..mu..g/dl) groups. However, with ether stress, experimental animals had a subnormal response, and the mean serum levels of corticosterone increased to only 23.9 ..mu../dl compared to 40.6 ..mu..g/dl in the controls. Exogenous ACTH stimulation produced a mean level of 19.0 ..mu..g/dl in the CH/sub 3/Hg-treated animals and 49.7 ..mu..g/dl in the controls. In vitro studies demonstrated a defect in the conversion of cholesterol to pregnenolone. A profound impairment in swimming was partially reversed with glucocorticoid therapy. In animals treated with CH/sub 3/Hg, serum testosterone was lower than normal in the basal state. Human chorionic gonadotropin stimulation increased the mean serum concentration of testosterone to 23.4 ng/ml in controls, but it was only 4.50 ng/ml in experimental animals. The data indicate that CH/sub 3/Hg poisoning impairs adrenal and testicular steroid hormone secretion, which accounts in part for the diminished stress tolerance and decreased sexual activity observed in CH/sub 3/Hg-intoxicated animals.

  7. Limitations and challenges in treatment of acute chemical warfare agent poisoning.

    2013-12-05

    Recent news from Syria on a possible use of chemical warfare agents made the headlines. Furthermore, the motivation of terrorists to cause maximal harm shifts these agents into the public focus. For incidents with mass casualties appropriate medical countermeasures must be available. At present, the most important threats arise from nerve agents and sulfur mustard. At first, self-protection and protection of medical units from contamination is of utmost importance. Volatile nerve agent exposure, e.g. sarin, results in fast development of cholinergic crisis. Immediate clinical diagnosis can be confirmed on-site by assessment of acetylcholinesterase activity. Treatment with autoinjectors that are filled with 2mg atropine and an oxime (at present obidoxime, pralidoxime, TMB-4 or HI-6) are not effective against all nerve agents. A more aggressive atropinisation has to be considered and more effective oximes (if possible with a broad spectrum or a combination of different oximes) as well as alternative strategies to cope with high acetylcholine levels at synaptic sites should be developed. A further gap exists for the treatment of patients with sustained cholinergic crisis that has to be expected after exposure to persistent nerve agents, e.g. VX. The requirement for long-lasting artificial ventilation can be reduced with an oxime therapy that is optimized by using the cholinesterase status for guidance or by measures (e.g. scavengers) that are able to reduce the poison load substantially in the patients. For sulfur mustard poisoning no specific antidote is available until now. Symptomatic measures as used for treatment of burns are recommended together with surgical or laser debridement. Thus, huge amounts of resources are expected to be consumed as wound healing is impaired. Possible depots of sulfur mustard in tissues may aggravate the situation. More basic knowledge is necessary to improve substantially therapeutic options. The use of stem cells may provide a new

    Ciguatera Fish Poisoning (CFP), a significant public health problem in the Pacific, is intrinsically linked to the health of coral reef ecosystems. Incidence data on CFP could therefore be used, in theory, as indicators of disruption to coral reefs. Some disruptions, such as increasing sea surface temperatures, result from global environmental change--therefore suggesting that CFP is likely to become an increasing public health problem in the region. The proactive management of increasing numbers of cases will depend on an understanding of the ecology of the disease, sound health surveillance systems to report cases of CFP including appropriate case definitions, and quantifiable correlations between case numbers and environmental variables. Here, we briefly review the knowledge about these components in Pacific Island Countries and Territories (PICTs), including summarising regional variation in symptoms of CFP cases, investigating media as an enhanced surveillance tool, and summarising regional environmental drivers of CFP cases. We conclude that CFP could be an important indicator of the health of reef ecosystems in the face of global climate change and more novel approaches such as combining environmental and health data, need to be implemented to improve surveillance of CFP.

  9. The Kidney in Lead Poisoning

    Kidney damage due to lead is still an interesting problem of industrial toxicology. In spite of abundant literature data, much still remains to be explained. There are controversial opinions, not only on the type of renal lesions due to lead, but also on whether lead affects the kidney at all. In this paper our clinical observations on the effect of lead upon the kidney in 53 patients suffering from lead poisoning are presented. In 44 patients (40 men and four women) lead poisoning was due to occupation, and in nine (five men and four women) to the use of lead-glazed pottery. The length of exposure varied from two months to 35 years. In all cases the diagnosis of lead poisoning was made clinically and confirmed by laboratory tests. Permanent changes in the form of chronic nephropathy were observed in only two patients. These were the two cases in which exposure to lead was the longest and most intense. Twenty-three patients showed functional renal lesions tending to normalize. In addition to the cases of organic nephropathy, blood pressure was persistently raised in one further patient; in two patients a raised blood pressure was observed only in the acute stage of poisoning. On the basis of these findings we consider that lead intoxication can cause renal lesions. These lesions are for the most part functional and temporary. In cases of long and severe exposure and repeated lead intoxication, organic renal lesions seem possible. The disturbances of renal function observed in this study may be ascribed to disordered intrarenal circulation, due to the spastic effect of lead on intrarenal blood vessels, and to a direct toxic or indirect hypoxic effect of lead on the tubules. When investigating renal function, we have observed that the timing of individual tests is of paramount importance. Some lesions are subject to changes in the natural course of lead poisoning, and unless this is borne in mind, apparently contradictory results may be obtained. PMID:13739013

    Methylmercury (MM) is a very potent neurotoxic agent. Its role in polluting the environment is well documented. A vast amount of study over the past several decades has finally provided insight into many aspects of its effect. Exposure to MM may be through ingestion of poisoned fish or inadvertent misuse of grain treated with the poison as a fungicide. Major epidemics have occurred in Japan (Fetal Minamata disease), Iraq, Pakistan, Guatemala, and Ghana. Sporadic incidences have occurred in the United States and Canada. There is no effective antidote to counteract the effect of MM on the central nervous system, although the information documented should provide hope for more effective therapy in acute cases.

    Blister formation and eccrine sweat gland necrosis is a cutaneous manifestation associated with states of impaired consciousness, most frequently reported after overdoses of central nervous system depressants, particularly phenobarbital. The case of a 45-year-old woman who developed "coma blisters" at six distinct anatomic sites after confirmed (laboratory) phenobarbital poisoning, associated with other central nervous system depressants (clonazepam, promethazine, oxcarbazepine and quetiapine), is presented. A biopsy from the left thumb blister taken on day 4 revealed focal necrosis of the epidermis and necrosis of sweat gland epithelial cells; direct immunofluorescence was strongly positive for IgG in superficial blood vessel walls but negative for IgM, IgA, C3 and C1q. The patient was discharged on day 21 with no sequelae.

    The outbreak of methylmercury poisoning in the geographic areas around Minamata Bay, Kumamoto, Japan in the 1950s has become known as Minamata disease. Based on earlier reports and extensive pathological studies on autopsied cases at the Kumamoto University School of Medicine, destructive lesions in the anterior portion of the calcarine cortex and depletion predominantly of granular cells in the cerebellar cortex came to be recognized as the hallmark and diagnostic yardstick of methylmercury poisoning in humans. As the number of autopsy cases of Minamata disease increased, it became apparent that the cerebral lesion was not restricted to the calcarine cortex but was relatively widespread. Less severe lesions, believed to be responsible for the motor symptoms of Minamata patients, were often found in the precentral, postcentral, and lateral temporal cortices. These patients also frequently presented with signs of sensory neuropathy affecting the distal extremities. Because of few sufficiently comprehensive studies, peripheral nerve degeneration has not been universally accepted as a cause of the sensory disturbances in Minamata patients. The present paper describes both biopsy and autopsy findings of the peripheral nerves in a male fisherman who died at the age of 64 years and showed the characteristic central nervous system lesions of Minamata disease at autopsy. A sural nerve biopsy with electron microscopy performed 1 month prior to his death showed endoneurial fibrosis and regenerated myelin sheaths. At autopsy the dorsal roots and sural nerve showed endoneurial fibrosis, loss of nerve fibers, and presence of Büngner's bands. The spinal cord showed Wallerian degeneration of the fasciculus gracilis (Goll's tract) with relative preservation of neurons in sensory ganglia. These findings support the contention that there is peripheral nerve degeneration in Minamata patients due to toxic injury from methylmercury.

    A 53-year-old woman ingested about 300 mL of 95% methanol. After immediate ethanol antagonist therapy and hemodialysis, she recovered completely. Few days later, the plasma concentration of methanol and formate was measured. A gas chromatography was used for the plasma methanol concentration measurement, and a colorimetric method was used for plasma formate concentration measurement (Formate Colorimetric Assay Kit; BioVision, California, USA). Patient's plasma methanol concentration before hemodialysis was 676.9 mg/dL and plasma formate concentration was 16.9 mg/dL. By removing blood methanol and formate using hemodialysis before formate accumulations in the body, the patient was discharged without any sequelae. We were able to obtain correlation between a gas chromatography and colorimetric method without gas chromatography-mass spectrometry, with good correlation coefficients. The sensitivity was sufficient for analyzing blood sample. Monitoring formate concentration is useful in determining the treatment and evaluating the prognosis of methanol poisoning. We suggest that this colorimetric method is useful in a facility with no access to a gas chromatography in order to measure a plasma formate concentration.

    Zinc phosphide (ZnP) containing rodenticide poisoning is a recognized cause of acute liver failure (ALF) in India. When standard conservative measures fail, the sole option is liver transplantation. Records of 41 patients admitted to a single centre with ZnP-induced ALF were reviewed to identify prognostic indicators for requirement of liver transplantation. Patients were analyzed in two groups: group I (n = 22) consisted of patients who either underwent a liver transplant (n = 14) or died without a transplant (n = 8); group II (n = 19) comprised those who survived without liver transplantation. International normalized ratio (INR) in group I was 9 compared to 3 in group II (p < 0.001). Encephalopathy occurred only in group I. Model for End-Stage Liver Disease (MELD) score in group I was 41 compared to 24 in group II (p < 0.001). MELD score of 36 (sensitivity of 86.7 %, specificity of 90 %) or a combination of INR of 6 and encephalopathy (sensitivity of 100 %, specificity of 83 %) were the best indicators of mortality. Such patients should undergo urgent liver transplantation.

    Everywhere today, poisonings present a significant and continuous increase of incidence in illness. Poisonings with organophosphates are more and more often. We do not have accurate statistics for this problem. The aim of this work was to present the clinical characteristics of poisoning with organophosphates, treated in University Clinical Centre in Prishtina. With the retrospective method, 23 patients were analyzed, 18 female and 5 male. Out of these, to (43.5%) have had tentative suicide, while 13 (56%) were accidentally exposed to poison. Poisoning with organophosphates was present in 3.8% of the overall number of poisonings. Organophosphate that was found in the analyzed poisoned patients was malathion (known here as Etiol). Average hospitalization time was 8.8 days (1 - 50 days range), average age of the patients was 27.1 years. Mortality scale was 52.1%. All these patients were treated with atropine. Atropine was given in intravenous way during 4.2 +/- 3.5 days and the average total dose was 82 +/- 61.5 mg. Pralidoxime antidote was not given to any of the patients. In adults, the poisoning was done mainly with the aim of suicide. Poisoned children with Etiol are in larger numbers from rural areas.

    Two men aged 19 and 21 years ingested 1 g and 4 g respectively from 3 kg of a white crystalline powder that they thought was a substance of abuse. It was later identified as almost pure arsenic trioxide. Both had nausea and vomiting and one developed acute renal failure. Each was treated with 2,3-dimercaptopropanesulphonate (DMPS), and made a full recovery with no evidence of prolonged renal or neurological impairment. The DMPS-arsenic complex is probably associated with lower penetration into the CNS and as a consequence treatment with DMPS may result in lower acute and chronic neurotoxicity than treatment with the currently standard recommended chelating agent dimercaprol (British Anti-Lewisite; BAL).

    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.

In the process of a comparative valuation of the using of heptral (ademethionin) and remaxol in the intensive therapy of alcohol poisonings it has been revealed that the using of remaxol led to improvement of the clinic of that poisonings, what had been registered as a decrease of frequency and duration of an alcohol delirium from 33,9% to 10,8%, a decrease of frequency of secondary lung complication from 18,5 to 3,1%, a decrease of a duration of treatment in intensive care unit from 7,3 +/- 0,6 to 5,6 +/- 0,3 and a hospital treatment duration from 11,8 +/- 0,5 to 9,0 +/- 0,3 days. Biochemical investigation has shown that using as heptral, as remaxol led to improvement of lever damages due to alcohol. However remaxol compared with heptral was better in the treatment of metabolic violations.

  17. Digoxin-Specific Antibody Fragment Dosing: A Case Series.

    PubMed

    Chhabra, Neeraj; Valento, Matthew; Bryant, Sean M; Aks, Steven E

    Digoxin-specific antibody fragments (DSFab) are used for the treatment of poisoning by cardiac glycosides, such as pharmaceutical digoxin. Dosing of this therapy for chronic and acute poisonings is based on the steady-state serum concentrations of digoxin, historical data in acute ingestions, or empiric regimens purportedly based on the average requirements. Empiric dosing for adult patients involves utilization of 3-6 vials for chronic poisoning and 10-20 vials for acute poisoning. The aim of this study was to describe the average dosing requirements based on the steady-state serum concentration of digoxin or historical data and compare this with the empiric dosing regimens. We performed a retrospective analysis of cases over an 11-year period presented to the Illinois Poison Center where administration of DSFab was recommended. We identified 140 cases of chronic digoxin poisoning and 26 cases or acute digoxin poisoning for analysis. The average dose of DSFab recommended in the cases of chronic digoxin poisoning was 3.05 vials (SD ± 1.31). The average dose of DSFab recommended in the cases of acute digoxin poisoning was 6.33 vials (SD ± 5.26). These values suggest that empiric dosing regimens may overestimate the need for DSFab in cases of both chronic and acute poisonings of pharmaceutical digoxin.

    A 26-year-old man was found dead in his car. All doors and windows were locked inside. The ignition key was in the "on" position; but the engine was not running and the fuel tank was empty. His post-mortem lividity was cherry-pink, and marked congestion was observed in the lungs and brain macroscopically. Massive intracardiac blood containing a small amount of cruor was found in the heart. In histological examination of the heart, partial disarrangement or necrosis was found in the myocardium. The liver cells showed derangement and degenerative changes, with focal lymphocyte infiltration in the portal regions, although they were not severe. The chemical tests showed that the blood concentration of carboxyhemoglobin was 46.6%. Stimulants were also detected from his blood and urine; the concentrations of methamphetamine and amphetamine were 3.25 and 0.84 microg/ml, respectively, for his cardiac blood. Therefore, it seemed reasonable to judge that the cause of his death was carbon monoxide poisoning; the cardiomyopathy and the presence of stimulants in blood might facilitate his death. Upon careful investigation of his car, it was disclosed that exhaust gas, leaked from small holes of the exhaust pipe due to rust-through, invaded the interior through four holes on the floor of the car during parking with the engine being on for the purpose of air-conditioning of the interior. It is very common to commit suicide by introducing exhaust gas into an interior of a closed motor car, but the present accidental case of carbon monoxide poisoning in a car seems rare and worthwhile reporting.

    In children presenting to hospital with gastrointestinal symptoms, diseases such as intussusception and acute appendicitis require particular attention and careful examination. Early diagnosis and proper treatment are important because of possible severe complications such as peritonitis and death. Intussusception and appendicitis share similar clinical manifestations. More importantly, the presence of acute appendicitis together with intussusception in children is very rare. We describe an interesting case of a 38-month-old boy who presented with abdominal pain in the right lower quadrant. His vital signs were stable and laboratory test findings showed no specific alterations. We detected tenderness in the right lower quadrant. A computed tomography scan showed an ileocolic intussusception with no strangulation and diffuse wall thickening of the appendix trapped within the intussusception. The patient underwent an appendectomy and manual reduction. PMID:26157700

    The primary objective of this article is to find new effective methods of diagnosis of urgent liver transplantation after Amanita phalloides intoxication amongst pediatric patients. The research was carried out using a medical database of pediatric patients who suffered from acute liver failure after amatoxin consumption. After data preprocessing and attribute selection steps, a two-phase experiment was conducted, which incorporated a wide variety of data mining algorithms. The results deliver two equivalent classification models with simple decision structure and reasonable quality of surgery prediction.

    In recent years, the number of drug- or toxin-related criminal cases has gradually increased, and accordingly the establishment of precise forensic autopsy examinations and appropriate chemical analysis is of urgent importance so that such cases are not overlooked. To this end, the author has set up a general instructional objective comprising "preparation of the most suitable analytical procedures for elucidation of drug- and/or poison-related cases in a forensic medicine laboratory". Specific objectives within the general instructional objective consist of the following: 1) securing adequate manpower, 2) swift acquisition and accumulation of the latest scientific information, 3) sufficient examinations during forensic autopsy, 4) appropriate collection and storage of human tissues, 5) enforcement of preliminary tests and routine examinations, 6) selection of proper analytical procedures and instruments for qualitative and quantitative analysis, 7) establishment of reliable quantitative analysis, 8) signification of quantitative data, 9) preparation of an accurate analytical report. In our laboratory, we have been able to analyze many kinds of acidic and basic substances as well as volatile hydrocarbons, alcohol and carboxyhemoglobin through the use of absorptimetry, gas chromatography, gas chromatography/mass spectrometry and high performance liquid chromatography, however it is thought that more skillful techniques should be developed as soon as possible with regard to the analysis of inorganic and water-soluble agents.

    Background: Organophosphorus compound poisoning (OPCP) is a major public health problem in developing countries like India. Atropine and oximes remain the main-stay of management. Magnesium sulfate (MgSO4) has shown benefit in the management of OPCP. Aims: This study was designed to assess the effect of MgSO4 on outcome in OPCP patients admitted to Intensive Care Unit (ICU). Settings and Design: Double-blind prospective randomized clinical trial in an ICU of tertiary care institution. Methods: One hundred patients (50 in each group) of OPCP, confirmed by history and syndrome of OPCP with low plasma pseudocholinesterase, aged between 18 and 60 years were studied. Magnesium group (Group M) received 4 g of 20% MgSO4 infusion over 30 min at admission to ICU, control group (Group C) received normal saline placebo in the same manner. Patients were assessed for the need for intubation, requirement of atropine, duration of mechanical ventilation, duration of ICU stay, and its effect on mortality. Statistical Analysis: Chi-square test and Fisher's exact test for categorical data, independent sample t-test, and paired t-test for nominal data. Results: Demographics and basal serum magnesium levels were comparable. Atropine requirement was higher in Group C (74.82 ± 22.39 mg) compared to Group M (53.11 ± 45.83 mg) (P < 0.001). A total of 33 patients in Group C and 23 patients in Group M required intubation, respectively (P = 0.043). The mean duration of mechanical ventilation was 4.51 ± 2 days in Group C compared to 4.13 ± 1.6 days in Group M (P = 0.45). ICU stay was 5.36 ± 2.018 days in Group C compared to 4.54 ± 1.581 days in Group M (P = 0.026). There was no significant difference in mortality between the groups. Conclusion: Four grams of MgSO4 given to OPCP patients within 24 h of admission to ICU, decreases atropine requirement, need for intubation, and ICU stay. PMID:28298783

    The superwarfarin-type anticoagulant rodenticides are used throughout the world and distinguish themselves from warfarin for its high potency and long acting anticoagulant activity. Easy access to these products enables the accidental or deliberate human poisoning. A case of voluntary rodenticide poisoning (RATIBRONÂ) by a woman who ingested an estimated 27.5 mg of bromadiolone total quantity for two weeks, with minor bleeding episodes, whose reversal of the anticoagulant effect with the correction of the abnormal values of the clotting tests took about one month to reverse is reported here. The correction of the haemostasis defects takes usually a long time and there are no treatment guidelines, but a gradually vitamin K dosage reduction, as out patients, along with the monitoring of the International Normalized Ratio levels, allows a safe evaluation of the therapeutic response.

At one of the patients biopsy was performed twice at the other three times. Patient having jaundice were admitted to hospital because of the suspected acute viral hepatitis. Laboratory findings have shown an acute parenchymal lesion. By light microscopy at one of them mid-zonal, at the other centro-lobular necrosis of hepatic cells further lipoid droplets of the cytoplasma of hepatocytes were revealed. Electronmicroscopically in the first biopsy specimens, and at one of the ptients at the second biopsy as well mostly damage to the mitochondria (enormous osmiophilia of the matrix, presence of osmiophil granules) and enlargement of the tubules of the endoplasmic reticulum could be seen. The controll clinical and morphological findings evidenced the reversible character of the process. Authors stress the differences existing between hepatic lesions caused by CCl4 at different persons on one side, and at rat and human liver on the other.

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

    Organophosphorus (OP) pesticides are a diverse class of acetylcholinesterase (AChE) inhibitors that are responsible for tremendous morbidity and mortality worldwide, killing approximately 300,000 people annually. Enzymatic hydrolysis of OPs is a potential therapy for acute poisoning. OpdA, an OP hydrolase isolated from Agrobacterium radiobacter, has been shown to decrease lethality in rodent models of OP poisoning. This study investigated the effects of OpdA on AChE activity, plasma concentrations of OP, and signs of toxicity after administration of dichlorvos to nonhuman primates. A dose of 75 mg/kg dichlorvos given orally caused apnea within 10 minutes with a progressive decrease in heart rate. Blood AChE activity decreased to zero within ten minutes. Respirations and AChE activity did not recover. The mean dichlorvos concentration rose to a peak of 0.66 μg/ml. Treated monkeys received 1.2 mg/kg OpdA iv immediately after poisoning with dichlorvos. In Opda-treated animals, heart and respiratory rates were unchanged from baseline over a 240-minute observation period. AChE activity slowly declined, but remained above 25% of baseline for the entire duration. Dichlorvos concentrations reached a mean peak of 0.19 μg/ml at 40 minutes after poisoning and decreased to a mean of 0.05 μg/ml at 240 minutes. These results show that OpdA hydrolyzes dichlorvos in an African Green Monkey model of lethal poisoning, delays AChE inhibition, and prevents lethality. PMID:24447378

    Although many cases of fatal hydrogen sulfide poisoning have been reported, in most of these cases, it resulted from the accidental inhalation of hydrogen sulfide gas. In recent years, we experienced 17 autopsy cases of fatal hydrogen sulfide poisoning due to the inhalation of intentionally generated hydrogen sulfide gas. In this study, the concentrations of sulfide and thiosulfate in blood, urine, cerebrospinal fluid and pleural effusion were examined using GC/MS. The sulfide concentrations were blood: 0.11-31.84, urine: 0.01-1.28, cerebrospinal fluid: 0.02-1.59 and pleural effusion: 2.00-8.59 (μg/ml), while the thiosulfate concentrations were blood: 0-0.648, urine: 0-2.669, cerebrospinal fluid: 0.004-0.314 and pleural effusion: 0.019-0.140 (μmol/ml). In previous reports, the blood concentration of thiosulfate was said to be higher than that of sulfide in hydrogen sulfide poisoning cases, although the latter was higher than the former in 8 of the 14 cases examined in this study. These results are believed to be strongly influenced by the atmospheric concentration of hydrogen sulfide the victims were exposed to and the time interval between exposure and death.

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

    Mechanical cardiopulmonary resuscitation (m-CPR) devices are an alternative to manual CPR, but their efficacy has been subject to debate. We present a case of a patient with full-neurologic recovery after prolonged m-CPR. The patient presented with severe hypothermia (internal temperature 24°C) and poisoning (sedatives/hypnotics). Hepatic perfusion and metabolism are considered keys to restore spontaneous circulation. During this period no problems related to the device or patient positioning were encountered. Delivery of high-quality CPR and prolonged resuscitation were achieved. We confirm that ventilations asynchronous with chest compressions can be a problem. Reduction in chest measurements can hamper lung ventilation. A synchronous mode of manual ventilation (30 : 2) seems to be the best solution. The patient had an initial period of manual CPR. No damage to any organ or structure was noted. This case is of further interest because our EMS helicopters can fly 24 hours a day and m-CPR devices could play an important role as a "bridge" in patients when active rewarming by cardiopulmonary bypass is indicated (CPB).

    We report a case of fatal outcome poisoning by massive exposure to hydrogen sulfide of a sewer worker. This rare event was associated with a moderate intoxication of two members of the rescue team. The death was due to asystole and massive lung oedema. Autopsy analysis showed diffuse necrotic lesions in lungs. Hydrogen sulfide is a direct and systemic poison, produced by organic matter decomposition. The direct toxicity mechanism is still unclear. The systemic toxicity is due to an acute toxicity by oxygen depletion at cellular level. It is highly diffusable and potentially very dangerous. At low concentration, rotten egg smell must trigger hydrogen sulfide suspicion since at higher concentration it is undetectable, making intoxication possible. In case of acute intoxication, there is an almost instantaneous cardiovascular failure and a rapid death. Hydrogen sulfide exposure requires prevention measures and more specifically the use of respiratory equipment for members of the rescue team.

    Acute kidney injury (AKI) has diverse causes and is associated with increased mortality and morbidity. In less developed countries (LDC), nephrotoxic AKI (ToxAKI) is common and mainly due to deliberate ingestion of nephrotoxic pesticides, toxic plants or to snake envenomation. ToxAKI shares some pathophysiological pathways with the much more intensively studied ischaemic AKI, but in contrast to ischaemic AKI, most victims are young, previously healthy adults. Diagnosis of AKI is currently based on a rise in serum creatinine. However this may delay diagnosis because of the kinetics of creatinine. Baseline creatinine values are also rarely available in LDC. Novel renal injury biomarkers offer a way forward because they usually increase more rapidly in AKI and are normally regarded as absent or very low in concentration, thereby reducing the need for a baseline estimate. This should increase sensitivity and speed of diagnosis. Specificity should also be increased for urine biomarkers since many originate from the renal tubular epithelium. Earlier diagnosis of ToxAKI should allow earlier initiation of appropriate therapy. However, translation of novel biomarkers of ToxAKI into clinical practice requires better understanding of non-renal factors in poisoning that alter biomarkers and the influence of dose of nephrotoxin on biomarker performance. Further issues are establishing LDC population-based normal ranges and assessing sampling and analytical parameters for low resource settings. The potential role of renal biomarkers in exploring ToxAKI aetiologies for chronic kidney disease of unknown origin (CKDu) is a high research priority in LDC. Therefore, developing more sensitive biomarkers for early diagnosis of nephrotoxicity is a critical step to making progress against AKI and CKDu in the developing world. PMID:26099916

    This paper describes two fatalities, three non-fatal intentional and three accidental oral ingestions of yew (Taxus baccata) leaves. In all cases the post-mortem external examinations showed no signs of violence. Internal examinations revealed small green, needle-like particles on the tongue, in the esophagus and in the stomach. Yew leaves were also identified in the stomach contents, whereas Taxus leaves were cut into small pieces and then ingested in one case. The analytical method used was based on a liquid-liquid-extraction under alkaline conditions followed by LC-MS/MS analysis (QTRAP 5500). Chromatographic separation was achieved by HPLC on a Kinetex C18 2.6u (100×3) mm. The analytical method allows the simultaneous identification and quantification of the commercially available yew alkaloids taxoids (m/z): paclitaxel (854.2→105.0/286.1), 10-deacetyltaxol (10-DAT: 812.2→105.0/286.1), baccatin III (BAC III: 604.0→105.0/327.0), 10-deacetylbaccatin III (10-DAB III: 562.1→105.0/327.0), cephalomannine [taxol B] (562.1→105.0/327.0) and of 3,5-dimethoxyphenol (3,5-DMP: 155.0→111.9/122.9) also encompassing the qualitative analysis of the alkaloidal diterpenoids (Q1→194.0/107.0); reference mass spectra obtained from a yew leaves extract: monoacetyltaxine (MAT: 568.4), taxine B (584.2), monohydroxydiacetyltaxine (MHDAT: 626.4), triacetyltaxine (TAT: 652.4), monohydroxytriacetyltaxine (MHTAT: 668.4). In both fatalities, paclitaxel, 10-DAT and cephalomannine were not identified in urine, cardiac and femoral blood but all taxoids and 3,5-DMP were present in stomach content and excreted into the bile. In urine, highest 3,5-DMP concentration was 7500 μg/L and 23,000 μg/L after enzymatic hydrolysis, respectively. In intentional and accidental poisonings, when electrocardiogram (ECG) examinations revealed ventricular tachycardia and/or prolonged QRS intervals, taxines were identified in plasma/serum, even after the ingestion of a few number of yew leaves

    2008-01-01

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

    The renewed interest in mycology has been reflected in growing use of wild mushrooms in culinary, driven by its nutritional, organoleptic and commercial value. However, the international scientific literature describes several syndromes of poisoning by mushrooms. We live, therefore, a paradigm conducive to an increase of mycetism, whose diagnosis requires a high level of suspicion and knowledge of clinical profiles. In Portugal, the real dimension of this problem is unknown. Although some mycetisms, such as the hepatotoxic syndrome, have high morbidity and mortality, their relative incidences are unknown. Add up to the shortage of international scientific literature, often outdated and inappropriate to clinical practice. In this context, this article provides an updated epidemiological and clinical perspective emphasizing a narrative and descriptive information on the forms of presentation, differential diagnosis and therapeutic approach, with the ultimate goal of the elaboration of a national diagram-oriented approach to decision-making diagnosis. We analyzed all the clinical records of patients admitted into ten hospitals between 1990 and 2008, notified with the code 988.1 of GDH (acute poisoning by mushrooms). There were registered demographic data, way of presentation, time between ingestion and onset of symptoms, the annual distribution, clinical profile, clinical and analytical treatment performed and complications. We identified 93 cases of acute poisoning by mushrooms, with equal gender distribution and inclusion of individuals of all age groups (from 1 to 85 years), but with greater representation from 21 to 50 years. There was a bimodal seasonal pattern, with a higher peak between September and December and a second in the spring. The hepatotoxic profile presentation corresponded to 63.4% and 31.7% of the cases to gastroenteritis syndrome. The mortality in cases of hepatotoxicity was 11.8%.

    Fulminant hepatic failure (FHF), also known as fulminant hepatitis, is a rare and extremely serious condition with a high mortality rate. Its rapid evolution and complexity in managing the treatment, creates the need to provide some immediate care by a team that specialises in intensive care. This acute decompensation is usually associated with other disorders, such as coagulopathy and hepatic encephalopathy, being responsible for major complications that can lead to organ failure. In our region the most common origin is unknown, followed by acute infection with hepatitis B. The treatment of this syndrome is based on the general measures applicable to any critically ill patient: treat the cause and early detection of extrahepatic complications, urgent liver transplantation being one of the alternatives with a better prognosis. This article presents a case report describing the monitoring of an Irish woman of 20 years who was transferred from a hospital in Ibiza to a hospital in Barcelona, with a suspected diagnosis of FHF. Following the conceptual model of Virginia Henderson, the collaborative problems and nursing diagnoses are described, presenting a care plan according to NANDA (North American Nursing Association), NIC (Nursing Intervention Classification), NOC (Nursing Outcomes Classification). This case helps to establish an individualised care plan that provides guidance to nurse professionals in critical patient care by increasing the knowledge of FHF.

    We present four young patients with acute severe solar retinopathy after observation of the total eclipse on January 4, 2011 without appropriate eye protection. Funduscopic findings were accompanied by optical coherence tomography (OCT) investigation of the macula. All our patients were young (range 14-29 years). In three of the four patients we have been able to repeat OCT evaluation revealing that the retinal changes were reversible, but delineating mild pathology in the retinal pigment epithelium and photoreceptors. Best-corrected visual acuity in the fourth case was 6/24. In addition, macular edema, which has been previously described in literature, could not be demonstrated by OCT. In the two cases we performed an early fluorescein angiogram, no pathology was seen.

    There are currently no FDA-approved antidotes for H2S/sulfide intoxication. Sodium nitrite, if given prophylactically to Swiss Webster mice, was shown to be highly protective against the acute toxic effects of sodium hydrosulfide (∼LD40 dose) with both agents administered by intraperitoneal injections. However, sodium nitrite administered after the toxicant dose did not detectably ameliorate sulfide toxicity in this fast-delivery, single-shot experimental paradigm. Nitrite anion was shown to rapidly produce NO in the bloodstream, as judged by the appearance of EPR signals attributable to nitrosylhemoglobin and methemoglobin, together amounting to less than 5% of the total hemoglobin present. Sulfide-intoxicated mice were neither helped by the supplemental administration of 100% oxygen nor were there any detrimental effects. Compared to cyanide-intoxicated mice, animals surviving sulfide intoxication exhibited very short knockdown times (if any) and full recovery was extremely fast (∼15 min) irrespective of whether sodium nitrite was administered. Behavioral experiments testing the ability of mice to maintain balance on a rotating cylinder showed no motor impairment up to 24 h post sulfide exposure. It is argued that antagonism of sulfide inhibition of cytochrome c oxidase by NO is the crucial antidotal activity of nitrite rather than formation of methemoglobin.

    Fifteen cases of acute ciguatera poisoning were subjected to electrical studies on the sural and common peroneal nerves. Significant slowing of sensory conduction velocity and prolongation of the absolute refractory, relative refractory and supernormal periods were recorded. These findings indirectly suggest that ciguatoxin causes an abnormally prolonged sodium channel opening in nerve membranes.

    We describe here a paradigmatic case of mushroom poisoning mimicking a stroke. A 64-year old male was referred to the emergency department (ED) for a car accident. He was found diaphoretic, hypotensive, bradycardic, and slightly confused at presentation. No signs of trauma were observed on physical examination. The patient had weakness of the right limbs and bilateral severe myosis. The lab tests were normal, except for leukocytosis, mild hyperglycemia, mild hyperazotemia and moderate hypokalemia. The clinical picture, with the exception of miosis, was thereby suggestive for a stroke, which was also considered the cause of the car accident. The patients' wife, who was brought later to the ED, reported that the husband had suffered a stroke 4 years earlier, with residual right hemiparesis. She also referred that the patient showed signs of diaphoresis and confusion, and the car was intentionally driven into the ditch. Among other details, she referred that the husband ate mushrooms that she had personally collected 2 hours before taking the drive. Two mg of atropine, intravenous rehydration and potassium were hence administered in the suspicion of a cholinergic toxydrome, and complete clinical remission was rapidly obtained. Among the mixture of mushrooms eaten by the patient, a mycologist identified Armillaria Mellea (an edible mushroom) and notably Inocybe Fastigiata, a toxic muscarine-containing mushroom, easily confounded with Armillaria. After observation and oral rehydration, the patient was discharged.

    Cases of mushroom poisoning in Thailand have increased annually. During 2008 to 2014, the cases reported to the National Institute of Health included 57 deaths; at least 15 died after ingestion of amanitas, the most common lethal wild mushrooms inhabited. Hence, the aims of this study were to identify mushroom samples from nine clinically reported cases during the 7-year study period based on nuclear ITS sequence data and diagnose lethal peptide toxins using a reversed phase LC-MS method. Nucleotide similarity was identified using BLAST search of the NCBI database and the Barcode of Life Database (BOLD). Clade characterization was performed by maximum likelihood and Bayesian phylogenetic approaches. Based on BLAST and BOLD reference databases our results yielded high nucleotide similarities of poisonous mushroom samples to A. exitialis and A. fuliginea. Detailed phylogenetic analyses showed that all mushroom samples fall into their current classification. Detection of the peptide toxins revealed the presence of amatoxins and phallotoxins in A. exitialis and A. fuliginea. In addition, toxic α-amanitin was identified in a new provisional species, Amanita sp.1, with the highest toxin quantity. Molecular identification confirmed that the mushrooms ingested by the patients were members of the lethal amanitas in the sections Amanita and Phalloideae. In Thailand, the presence of A. exitialis was reported here for the first time and all three poisonous mushroom species provided new and informative data for clinical studies.

    Objective—To identify host and environment characteristics associated with poison exposure among preschool children in Thailand. Setting—A matched case-control study in 20 public hospitals in Khon Kaen province. Methods—Cases comprised 100 consecutive preschool children attending hospital between September 1997 and February 1999 because of reported exposure to a poison. Controls were three children matched by age, sex and area of residence to each case, who had never attended a hospital for this reason. Risk factors were elicited by interviewing the children's caregivers at their homes using a structured questionnaire and analyzed using conditional logistic regression. Results—Number of siblings, whether the child was "medicine eating" and "rushing to explore new objects", the child's activities while the caregiver was working during the daytime, the child's distance from the caregiver while the caregiver was working, whether the child was taken to a non-agricultural worksite, and the number of used containers around the residence, were all statistically significant in univariate analyses. However, when all significant variables were included in a multivariate model, only "medicine eating" and the number of used containers around the residence remained statistically significant. Conclusion—Attention to "medicine eating" and used containers through increased supervision could be a protective factor against poison exposure for these children. To reduce risk, caregivers should not refer to medicines as foods and used containers should be systematically collected for disposal or recycling. PMID:11565987

    Cyanobacteria (also called blue-green algae) are ubiquitous in aquatic environments. Some species produce potent toxins that can sicken or kill people, domestic animals, and wildlife. Dogs are particularly vulnerable to cyanotoxin poisoning because of their tendency to swim in and drink contaminated water during algal blooms or to ingestalgal mats.. Here, we summarize reports of suspected or confirmed canine cyanotoxin poisonings in the U.S. from three sources: (1) The Harmful Algal Bloom-related Illness Surveillance System (HABISS) of the National Center for Environmental Health (NCEH), Centers for Disease Control and Prevention (CDC); (2) Retrospective case files from a large, regional veterinary hospital in California; and (3) Publicly available scientific and medical manuscripts; written media; and web-based reports from pet owners, veterinarians, and other individuals. We identified 231 discreet cyanobacteria harmful algal bloom (cyanoHAB) events and 368 cases of cyanotoxinpoisoning associated with dogs throughout the U.S. between the late 1920s and 2012. The canine cyanotoxin poisoning events reviewed here likely represent a small fraction of cases that occur throughout the U.S. each year. PMID:24064718

    2007-10-01

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

    2009-01-01

    Introduction Numerous pathogens can cause infective endocarditis, including Haemophilus parainfluenzae. H. parainfluenzae is part of the H. aphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae group that may cause about 3% of the total endocarditis cases, and is characterized by a subacute course and large vegetations. Case presentation Acute H. parainfluenzae endocarditis developed in a 54-year-old woman, with no underlying predisposing factors. The patient presented with fever of 3 days duration and a severe headache. Magnetic resonance imaging of the brain revealed multiple cerebral emboli with hemorrhagic foci. Upon suspicion of endocarditis, cardiac transesophageal ultrasonography was performed and revealed massive vegetations. The patient underwent emergency mitral valve replacement, and was further treated with ceftriaxone. Blood cultures grew H. parainfluenzae only after valve replacement, and a 6-week course of ceftriaxone was prescribed. Conclusion We underline the typical presentation of large vegetations in H. parainfluenzae endocarditis, which are associated with embolic phenomena and resulting severity. Although the majority of the few cases reported in the literature are subacute in progress, our case further underlines the possibility that H. parainfluenzae endocarditis may develop rapidly. Thus, awareness of the imaging characteristics of the pathogen may enhance early appropriate diagnosis and therapeutic response. PMID:19830211

    Ciguatera is a foodborne poisoning caused by eating seafood from tropical and subtropical reef areas. According to official data from the local health department, cases of ciguatera in French Polynesia are estimated to involve 240 to 400 persons per 100 000 inhabitants. Associated with a wide spectrum of gastrointestinal, cardiovascular, nervous, and general signs, ciguatera is usually benign although some forms can lead to hospitalization. The purpose of this report is to describe two unusual cases involving patients who developed acute polyradiculoneuritis with Guillain-Barré-syndrome-like peripheral nervous system deficits on the seventh day of ciguatera after ingestion of moray eel. The hypothesis of an immune-allergic reaction is raised especially in the light of rapid improvement of the patient who received polyvalent immunoglobulin treatment.

    Acute normovolaemic haemodilution (ANH) is a technique used to preserve a patient's owns red blood cells and reduce the incidence of heterogeneous blood transfusion. This paper describes the use of the technique in a dog and a kitten. A significant benefit of ANH can be shown in the canine case presented. The dog lost 1800 ml of blood during surgery but the haematocrit was only reduced to 33% 6 hours after the end of surgery. The kitten, however, did not benefit from ANH. It lost a small volume of blood during surgery and developed complications. This paper also describes some of the potential complications that may occur. To the best of my knowledge, this is the 1st clinical description of ANH in a dog and a cat.

    There is a wide variation and lack of evidence in current recommendations for atropine dosing schedules leading to subsequent variation in clinical practice. Therefore, we sought to examine the safety and effectiveness of a titrated vs. ad hoc atropine treatment regimen in a cohort of patients with acute cholinesterase inhibitor pesticide poisoning. A prospective cohort study was conducted in three district secondary referral hospitals in Sri Lanka using a structured data collection form that collected details of clinical symptoms and outcomes of cholinesterase inhibitor pesticide poisoning, atropine doses, and signs of atropinization. We compared two hospitals that used a titrated dosing protocol based on a structured monitoring sheet for atropine infusion with another hospital using an ad hoc regime. During the study, 272 symptomatic patients with anticholinesterase poisoning requiring atropine were admitted to the three hospitals. Outcomes of death and ventilation were analyzed for all patients, 226 patients were prospectively assessed for atropine toxicity. At baseline, patients in the titrated dose cohort had clinical signs consistent with greater toxicity. This in part may be due to ingestion of more toxic organophosphates. They received less pralidoxime and atropine, and were less likely to develop features of atropine toxicity, such as delirium (1% vs. 17%), hallucinations (1% vs. 35%), or either (1% vs. 35%) and need for patient restraint (3% vs. 48%) compared with the ad hoc dose regime. After adjusting for the pesticides ingested, there was no difference in mortality and ventilatory rates between protocols. Ad hoc high dose atropine regimens are associated with more frequent atropine toxicity without any obvious improvement in patient outcome compared with doses titrated to clinical effect. Atropine doses should be titrated against response and toxicity. Further education and the use of a structured monitoring sheet may assist in more appropriate

  12. Glyphosate poisoning.

    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

    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.

    Methyl and ethyl alcohol poisoning are still responsible for high morbidity and mortality rates. The purpose of this retrospective study was to examine ethyl and methyl alcohol poisoning related deaths in Ankara and surrounding cities between 2001 and 2011 and compare them with previous studied conducted in Turkey and other countries. For this purpose, 10,720 medico-legal autopsy cases performed in Ankara Branch of the Council of Forensic Medicine were reviewed in terms of alcohol poisonings. The deaths due to methanol and ethanol poisoning were 74 (0.69% of all medico-legal autopsies performed) and the distribution among them was 35 (47.3%) for methanol poisoning and 39 (52.7%) for ethanol poisoning. Overwhelming majority of the cases were male (n = 67, 90.5%). The mean age of the victims was 44.9 ± 10.9 years and ranging from 21 to 92 years. The age group of 35-49 years was the mostly affected. Most of the cases were seen in 2004 (n = 12, 16.2%). The levels of postmortem blood alcohol levels were available for all cases and the mean alcohol levels were 322.8 ± 155.5 mg/dL ranging from 74 to 602 mg/dL for methanol and 396.8 ± 87.1 mg/dL and ranging from 136 to 608 mg/dL for ethanol. Early diagnosis is essential for successful treatment in methanol and ethanol poisoning. Besides increased awareness, more sensitive/specific diagnostic tools, and the prompt approach to the poisoned individual should be implemented in the hospitals.

    A double-wattled cassowary died following a clinical course of severe diarrhea, anorexia, and polydypsia. At necropsy, prolapse of the penis, severe enteritis, and swelling of the kidneys with subcapsular heavy deposits of urates were noted. Histologic lesions comprised nephrosis, interstitial edemia of the muscle, and sloughing of the intestinal villi. Leaves collected from the gizzard were identified as coast live oak (Quercus agrifolia). Diagnosis of oak poisoning was made based on the renal lesions and the finding of a high content of tannins in the liver and gastrointestinal tract. Oak poisoning has not been reported previously in avian species.

    Cyanide poisoning has existed for centuries. In most cases, cyanide is combined with other toxic substances; for example with carbon monoxide in fire smoke. Cases of pure cyanide poisoning are rare, and usually due to accidental exposure. Their treatment is based on oxygenation and the infusion of hydroxocobalamin. The seriousness of this type of poisoning calls for a rapid and specific response, which demonstrates the usefulness of non-hospital based medical treatment. The authors report here the case of a man who was the victim of occupational poisoning with sodium cyanide and who was treated at the workplace by fire-fighters and the Service Mobile d’Urgence et Reanimation emergency ambulance service.

    Levothyroxine (LT), T4, poisoning is rarely associated with a severe outcome. However, cases with significant complications have been reported. The aim of this study was to identify factors associated with symptoms of poisoning including late-onset symptoms. All enquiries to the Danish Poison Information Centre (DPIC) concerning LT poisoning between March 2007 and September 2012 were reviewed and the following parameters were recorded: age, dose, time from ingestion, multiple drug intake and symptoms. To evaluate the frequency of late-onset symptoms, a subgroup of patients without initial symptoms were contacted. A total of 181 patients were registered (112 children). Ingested LT dose ranged from 10 to 9000 mcg (median 275 mcg). A total of 29 of 181 (16%) patients were symptomatic at the time of enquiry, and there was no difference in ingested LT dose between asymptomatic and symptomatic patients, neither in children nor in adults (age 16-92 years) (p < 0.68 and p < 0.47, respectively). In total, 153 of 181 (85%) patients did not have symptoms of poisoning at the time of enquiry; however, in 9 of 21 (43%) patients, we were able to contact, late-onset symptoms existed. In none of the cases, hospital contact was needed and there were no reports of long-term sequelae. Acute LT poisoning often follows a benign course. The occurrence of symptoms appears not to be dose dependent. Late-onset symptoms seem to be common. However, all symptoms resolved spontaneously without need of medical care.

    A number of cases of acute myopericarditis mimicking acute myocardial infarction (AMI) have previously been reported in the literature. However, to the best of our knowledge, such a case resulting from Mycobacterium tuberculosis infection has not previously been described. The present study reports the case of a 21-year-old male patient presenting with acute chest pain, in whom focal ST-segment elevation and elevated cardiac enzymes mimicked a diagnosis of AMI. However, acute tuberculous myopericarditis was diagnosed on the basis of a variety of imaging examinations, laboratory tests, as well as the changes observed in electrocardiograms (ECGs) and in the cardiac enzyme levels. The case highlights the importance of a detailed collection of medical history, comprehensive explanations of serial ECGs, thoracic computed tomography, echocardiogram and coronary angiography in the diagnosis and differentiation of acute tuberculous myopericarditis mimicking AMI.

    A retrospective analysis of poisoning calls received by the National Poisons Information Centre showed a total of 2719 calls over a period of three years (April 1999-March 2002). The queries were made on poisoning management (92%) and information (8%) about various products and functioning of the centre. The data were analysed with respect to age, sex, mode and type of poisoning. The agents belonged to various groups: household products, agricultural pesticides, industrial chemicals, drugs, plants, animal bites and stings, miscellaneous and unknown groups respectively. The age ranged from less than 1 to 70 years, with the highest incidence in the range of 14-40 years, with males (57%) outnumbering females (43%). The most common mode of poisoning was suicidal (53%), followed by accidental (47%). The route of exposure was mainly oral (88%). Dermal (5%), inhalation and ocular exposure contributed 7% to the total. The highest incidence of poisoning was due to household agents (44.1%) followed by drugs (18.8%), agricultural pesticides (12.8%), industrial chemicals (8.9%), animals bites and stings (4.7%), plants (1.7%), unknown (2.9%) and miscellaneous groups (5.6%). Household products mainly comprised of pyrethroids, rodenticides, carbamates, phenyl, detergents, corrosives etc. Drugs implicated included benzodiazepines, anticonvulsants, analgesics, antihistamines, tricyclic antidepressants, thyroid hormones and oral contraceptives. Among the agricultural pesticides, aluminium phosphide was the most commonly consumed followed by organochlorines, organophosphates, ethylene dibromide, herbicides and fungicides. Copper sulphate and nitrobenzene were common among industrial chemicals. The bites and stings group comprised of snake bites, scorpion, wasp and bee stings. Poisoning due to plants was low, but datura was the most commonly ingested. An alarming feature of the study was the high incidence of poisoning in children (36.5%). The age ranged from less than 1 to 18 years

    may follow in time, accompanied rather frequently by arterial hypertension. A study of some of the cases followed for several years demonstrated this progressive evolution of lead nephropathy. A functional and transitory impairment of renal function is very probably caused by an impairment of intrarenal circulation, resulting from marked vasoconstriction of the renal vessels, forming part of the generalized vasoconstriction of lead poisoning. Prolonged exposure and frequently recurring episodes of acute poisoning may lead to progressive impairment of renal function and to the development of organic lesions. Special attention should be paid to renal function tests in all cases with prolonged exposure to lead in order to prevent the development of severe lead nephropathy. PMID:5663423

    Sodium dimercaptopropanesulphonate (DMPS) and sodium dimercaptosuccinate (DMS) were discovered to be effective antidotes for acute poisoning of insecticides SCD [sodium ammonium dimethyl-2-(propane-1,3-dithiosulfate) monohydrate], nereistoxin (4-N,N-dimethylamino-1,2-dithiolane) and cartap (dihydronereistoxin dicarbamate). In mice, DMPS (250 mg/kg) or DMS (1000 mg/kg) ip 20 min before SCD increased LD50 of ig SCD from 97 to 374 or 251 mg/kg, respectively. The prophylactic effect of DMPS was better than that of DMS. Administration of DMPS prior to cartap increased LD50 of ig cartap from 130 to 375 mg/kg. The therapeutic effect of DMPS was also demonstrated in SCD-poisoned conscious rabbits. DMPS 62.5 mg/kg or DMS 500 mg/kg iv completely antagonized the neuromuscular blockade and respiratory depression caused by SCD, nereistoxin and cartap in anesthetized rabbits. The antagonism of SCD-induced neuromuscular blockade by cysteine (400 mg/kg, iv) was less effective and of shorter duration than that by DMPS and DMS. Dimercaprol 50 mg/kg im showed little effect on SCD-induced paralysis. The antagonistic actions of sulfhydryl compounds on neuromuscular blockade induced by these insecticides probably belong to chemical antagonism.

  7. Acute coronary ischemia during alcohol withdrawal: a case report

    PubMed Central

    2011-01-01

    Introduction The potential of alcohol withdrawal to cause acute coronary events is an area that needs the urgent attention of clinicians and researchers. Case presentation We report the case of a 52-year-old heavy-alcohol-using Sri Lankan man who developed electocardiogram changes suggestive of an acute coronary event during alcohol withdrawal. Despite the patient being asymptomatic, subsequent echocardiogram showed evidence of ischemic myocardial dysfunction. We review the literature on precipitation of myocardial ischemia during alcohol withdrawal and propose possible mechanisms. Conclusions Alcohol withdrawal is a commonly observed phenomenon in hospitals. However, the number of cases reported in the literature of acute coronary events occurring during withdrawal is few. Many cases of acute ischemia or sudden cardiac deaths may be attributed to other well known complications of delirium tremens. This is an area needing the urgent attention of clinicians and epidemiologists. PMID:21838872

    Introduction Transfusion-related acute lung injury is emerging as a common cause of transfusion-related adverse events. However, awareness about this entity in the medical fraternity is low and it, consequently, remains a very under-reported and often an under-diagnosed complication of transfusion therapy. Case presentation We report a case of a 46-year old woman who developed acute respiratory and hemodynamic instability following a single unit blood transfusion in the postoperative period. Investigation results were non-specific and a diagnosis of transfusion-related acute lung injury was made after excluding other possible causes of acute lung injury. She responded to symptomatic management with ventilatory and vasopressor support and recovered completely over the next 72 hours. Conclusion The diagnosis of transfusion-related acute lung injury relies on excluding other causes of acute pulmonary edema following transfusion, such as sepsis, volume overload, and cardiogenic pulmonary edema. All plasma containing blood products have been implicated in transfusion-related acute lung injury, with the majority being linked to whole blood, packed red blood cells, platelets, and fresh-frozen plasma. The pathogenesis of transfusion-related acute lung injury may be explained by a "two-hit" hypothesis, involving priming of the inflammatory machinery and then activation of this primed mechanism. Treatment is supportive, with prognosis being substantially better than for most other causes of acute lung injury. PMID:18957111

    Patients with 47, XXY karyotype (Klinefelter syndrome) appear to have increased risk of developing cancer, especially male breast cancer, germ cell tumours and non Hodgkin lymphomas, but rarely acute myeloid leukaemia. We report a patient with acute basophilic leukaemia with 47, XXY karyotype in both the tumour and constitutional cells. Acute basophilic leukaemia is very rare disease comprising less than 1% of all acute myeloid leukaemias. Morphological characteristic of leukaemic blast cells is moderately basophilic cytoplasm containing a variable number of coarse basophilic granules. The most characteristic cytochemical reaction is metachromatic positivity with toluidine blue. Blast are myeloperoxidase negative. Also leukemic blasts express myeloid and monocyte markers. There is no consistent chromosomal abnormality identified in this leukaemia. This is the first reported case of acute basophilic leukaemia in patient with Klinefelter syndrome. In this article the medical history of the patient is given and the possible connection between Klinefelter syndrome and acute myeloid leukaemia is discussed.

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

    Background Delayed encephalopathy after acute carbon monoxide (CO) poisoning (DEACMP) commonly occurs after recovering from acute CO poisoning. This study was performed to assess the efficacy of the combined application of dexamethasone and hyperbaric oxygen (HBO) therapy in patients with DEACMP. Patients and methods A total of 120 patients with DEACMP were recruited and randomly assigned into the experimental group (receiving dexamethasone 5 mg/day or 10 mg/day plus HBO therapy) and control group (HBO therapy as monotherapy). Meanwhile, the conventional treatments were provided for all the patients. We used the Mini-Mental State Examination (MMSE) scale to assess the cognitive function, the National Institutes of Health Stroke Scale (NIHSS) to assess the neurological function and the remission rate (RR) to assess the clinical efficacy. Myelin basic protein (MBP) in the cerebrospinal fluid (CSF) was also measured. Results After 4 weeks of treatment, compared to the control group, the experimental group had a significantly higher remission rate (P=0.032), a significantly higher average MMSE score (P=0.037) and a significantly lower average NIHSS score (P=0.002). Meanwhile, there was a trend toward better improvement with dexamethasone 10 mg/day, and the level of MBP in the CSF of patients was significantly lower in the experimental group than in the control group (P<0.0001). The addition of dexamethasone did not significantly increase the incidence of adverse events. Conclusion These results indicate that the combined application of dexamethasone and HBO therapy could yield better efficacy for patients with DEACMP and should be viewed as a potential new therapy.

    Patient: Female, 28 Final Diagnosis: Acute transverse myelitis Symptoms: Ascending paralysis Medication: — Clinical Procedure: — Specialty: Infectious Diseases Objective: Rare disease Background: Acute transverse myelitis (ATM) is an uncommon and often overlooked complication of certain bacterial and viral infections that can have a rapid onset and result in severe neurological deficits. Case Report: This case report describes a previously healthy 28-year-old woman who presented to the trauma center after developing acute paralysis and paresthesias of all four extremities within the span of hours. The initial presumptive diagnosis was spinal cord contusion due to a fall versus an unknown mechanism of trauma, but eventual laboratory studies revealed Salmonella bacteremia, indicating a probable diagnosis of parainfectious ATM. Conclusions: This case illustrates the importance of considering the diagnosis of parainfectious ATM in patients presenting with acute paralysis with incomplete or unobtainable medical histories.

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

    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

    Organophosphorus (OP) compound poisoning is a major global public health problem. Acute OP insecticide self-poisoning kills over 200,000 people every year, the majority from self-harm in rural Asia. Highly toxic OP nerve agents (e.g., sarin) are a significant current terrorist threat, as shown by attacks in Damascus during 2013. These anticholinesterase compounds are classically considered to cause an acute cholinergic syndrome with decreased consciousness, respiratory failure, and, in the case of insecticides, a delayed intermediate syndrome that requires prolonged ventilation. Acute respiratory failure, by central and peripheral mechanisms, is the primary cause of death in most cases. However, preclinical and clinical research over the last two decades has indicated a more complex picture of respiratory complications after OP insecticide poisoning, including onset of delayed neuromuscular junction dysfunction during the cholinergic syndrome, aspiration causing pneumonia and acute respiratory distress syndrome, and the involvement of solvents in OP toxicity. The treatment of OP poisoning has not changed over the last 50 years. However, a better understanding of the multiple respiratory complications of OP poisoning offers additional therapeutic opportunities. PMID:25419614

    Foot drop is defined as the weakness of the foot and ankle dorsiflexion. Acute unilateral foot drop is a well-documented entity, whereas bilateral foot drop is rarely documented. Slowly progressing bilateral foot drop may occur with various metabolic causes, parasagittal intracranial pathologies, and cauda equina syndrome. Acute onset of bilateral foot drop due to disc herniation is extremely rare. Here we present two cases of acute bilateral foot drop due to disc herniation. The first patient was a 45-year-old man presented with acute bilateral foot drop, without any sign of the cauda equina syndrome. Lumbar magnetic resonance imaging of the patient revealed L4-5 disc herniation. To our knowledge, this is the first presented case of acute bilateral foot drop without any signs of cauda equina syndrome caused by L4-5 disc herniation. The second patient was a 50-year-old man who was also presented with acute bilateral foot drop, and had T12-L1 disc herniation with intradural extension. Also this is the first presented case of T12-L1 disc herniation with intradural extension causing acute bilateral foot drop. We performed emergent decompressive laminectomy to both of the patients and extrude disc materials were excised. Both of the patients were recovered with favorable outcome. PMID:25972945

    What is already known about this subject Poisoning with β-blockers can result in cardiovascular and central nervous system effects. Although much has been reported about metoprolol poisoning's cardiovascular complications, little attention has been paid to acute myocardial infarction (AMI) accompanied by elevated cardiac markers. What this study adds This case report demonstrates for the first time an association of metoprolol poisoning with acute myocardial infarction in a patient with a previous history of coronary artery disease. Metoprolol poisoning can induce acute myocardial reinfarction in patients with prior AMI or known coronary artery disease. In other words, metoprolol overdose can trigger myocardial ischaemia and dysrhythmia in patients with coronary artery disease. Aim To demonstrate that β-blocker poisoning results in cardiovascular and central nervous system findings. Methods A 56-year-old woman was brought to the emergency department, having been admitted to hospital with 1500 mg of metoprolol ingestion 2 h previously. She had undergone percutanerous transluminal coronary angioplasty and stenting because of acute myocardial infarction (AMI). Her ECG revealed ST segment elevation in inferior leads and junctional dysrhythmia. Her clinical symptoms relieved after pacing and hospitalization and she was discharged. Results Our patient demonstrated findings of AMI with hypotension and bradycardia that appeared to result from metoprolol poisoning. Although one patient has been reported to have AMI associated with metoprolol poisoning, our patient is unique with her ECG changes and elevated cardiac markers: this is the first time that AMI characterized by elevated cardiac markers associated with metoprolol toxicity has been reported. Conclusions Emergency physicians should bear in mind that AMI can accompany the presentation of metoprolol overdose in those with coronary artery disease. In other words, metoprolol poisoning can trigger myocardial ischaemia

    A 61-year-old male patient was admitted because of unexplained abdominal pain and anemia. His past medical history was unremarkable except for having taken herbal medicine to treat facial palsy two months ago. The result of health examination performed about a month ago showed increased serum aspartate and alanine aminotransferase level, and he was diagnosed with toxic hepatitis by herbal medicine. When the patient presented to the outpatient department three weeks ago, follow-up liver function test results showed improvement but he complained of abdominal pain. Despite extensive blood chemistry tests and computed tomography, the cause of pain could not be found. After much deliberation, serum lead level and herbal medicines analysis was performed based on the fact that he took herbal medicine two months ago, and he could finally be diagnosed with lead poisoning. Since the serum lead level was high enough to be indicated for lead chelating therapy, conservative management was given. When a patient with toxic hepatitis due to herbal medication presents with abdominal pain, the possibility of lead poisoning should always be taken into consideration.

    Acute disseminated encephalomyelitis (ADEM) is a disease of the central nervous system (CNS) mainly affecting children. It usually occurs within 2 days to 4 weeks following a triggering factor such a viral infection or an immunization. Clinical presentation is characterized by an acute encephalopathy and by multifocal neurologic abnormalities. In the absence of specific biologic marker, the diagnosis of ADEM is based on clinical, biological and radiological data including cerebrospinal fluid (CSF) analysis and magnetic resonance imaging (MRI). Brain MRI typically shows multifocal lesions predominantly involving the white matter. Treatment is based on high doses of steroids. Intravenous immunoglobulins or plasmapheresis are sometimes required. The prognosis is usually favorable but neurological sequellae can occur.

    A 43-year-old male, with no previous history of mental illness, was diagnosed with coronary heart disease, after which he became acutely depressed and attempted suicide by ingesting an organophosphate pesticide. He was admitted to an intensive care unit and treated with pralidoxime, atropine, and oxygen. His coronary occlusion pattern required early coronary artery bypass grafting (CABG) surgery. His family, apprehensive of a repeat suicidal attempt, requested surgery be performed as soon as possible. He recovered well from the OP poisoning and was mentally fit to express informed consent 2 weeks after admission. Seventeen days after poisoning, he underwent coronary artery bypass grafting and recovered uneventfully. Six years later, he remains in excellent health. We report this case because to the best of our knowledge there is no literature regarding CABG performed soon after organophosphate poisoning.

    There are several common causes of acute pancreatitis, principally excessive alcohol intake and gallstones, and there are many rare causes. However, cases of pancreatitis still occur in the absence of any recognizable factors, and these cases of idiopathic pancreatitis suggest the presence of unrecognized etiologies. Five cases of acute pancreatitis in four patients came to attention due to a strong temporal association with exposure to nerve stimulators and energy drinks. Given that these cases of pancreatitis were otherwise unexplained, and given that these exposures were not clearly known to be associated with pancreatitis, we performed a search for precedent cases and for mechanistic bases. No clear precedent cases were found in PubMed and only scant, weak precedent cases were found in public-health databases. However, there was a coherent body of intriguing literature in support of a mechanistic basis for these exposures playing a role in the etiology of pancreatitis. PMID:26600983

    Background Delayed encephalopathy after acute carbon monoxide (CO) poisoning (DEACMP) is one of the most serious complications after CO poisoning. This study was conducted to explore the efficacy of the combined application of N-Butylphthalide and hyperbaric oxygenation therapy (HBO) on cognitive dysfunction in patients with DEACMP. Material/Methods A total of 184 patients with DEACMP were randomly assigned to either receive HBO or N-Butylphthalide and HBO. Meanwhile, all patients received conventional treatment. The total remission rate (RR) was used to assess the clinical efficacy. The Mini-Mental State Examination (MMSE) was used to assess the cognitive function, and the National Institutes of Health Stroke Scale (NIHSS) was used to assess the neurological function. Results Finally, there were 90 and 94 patients in the control and experimental groups, respectively. After eight weeks of treatment, the total RR in the experimental group (47.9%) was significantly higher than that in the control group (33.3%). Compared to the control group, significantly more patients in the experimental group had MMSE scores of 24–30. The lower NIHSS score in the experimental group showed that N-Butylphthalide had the effect of preservation and restoration of neurological function. No obvious drug toxicity or liver and kidney dysfunction was observed, and there was no significant change in the level of blood glucose and blood lipids. Conclusions These results indicated that the combined application of N-Butylphthalide and HBO could significantly improve the cognitive dysfunction of patients with DEACMP and have great clinical efficacy, which should be further studied.

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

    Background Suicide in Sri Lanka is a major public health problem and in 1995 the country had one of the highest rates of suicide worldwide. Since then reductions in overall suicide rates have been largely attributed to efforts to regulate a range of pesticides. The evolution, context, events and implementation of the key policy decisions around regulation are examined. Methods This study was undertaken as part of a broader analysis of policy in two parts—an explanatory case study and stakeholder analysis. This article describes the explanatory case study that included an historical narrative and in-depth interviews. Results A timeline and chronology of policy actions and influence were derived from interview and document data. Fourteen key informants were interviewed and four distinct policy phases were identified. The early stages of pesticide regulation were dominated by political and economic considerations and strongly influenced by external factors. The second phase was marked by a period of local institution building, the engagement of local stakeholders, and expanded links between health and agriculture. During the third phase the problem of self-poisoning dominated the policy agenda and closer links between stakeholders, evidence and policymaking developed. The fourth and most recent phase was characterized by strong local capacity for policymaking, informed by evidence, developed in collaboration with a powerful network of stakeholders, including international researchers. Conclusions The policy response to extremely high rates of suicide from intentional poisoning with pesticides shows a unique and successful example of policymaking to prevent suicide. It also highlights policy action taking place ‘under the radar’, thus avoiding policy inertia often associated with reforms in lower and middle income countries. PMID:24362640

    1975-10-09

    The authors report ten cases of acute recurrent pericarditis observed over a period of 5 years and emphasize the frequency of these relapses involving 15 to 20% of cases of acute pericarditis. Usually, no cause is found and, althrough an immunological mechanism has been suggested, there is no common test which may confirm or disprove this theory. The risk of ultimate constrictive pericarditis is minimal and this risk is thus not taken into consideration in deciding on treatment. On the other hand, the undesirable effects of corticosteroids which favour relapses, seem to be demonstrated. The use of corticosteroids in cases of acute pericarditis should thus be exceptional and one should prefer non-steroid anti-inflammatory drugs. Immunosuppressors and pericardectomy should be reserved for the rare forms where the disease progresses and relapses continue after cortisone has been stopped.

    Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed.

    2007-01-01

    Background Acute encephalomyelopathy occurring after an allogeneic bone marrow transplant for leukaemia is a diagnostic emergency. The diagnosis can be challenging since there is a wide set of alternative diagnoses, including opportunistic infections and relapse of the leukaemia. Case presentation A 13-year old girl presented with a severe acute myelopathy and encephalopathy. She was in prolonged remission from a central nervous system and bone marrow relapse of an acute lymphoblastic leukaemia, treated with allogeneic bone marrow transplantation. Neuroimaging showed multifocal grey and white matter lesions of demyelinating appearance in the brain and entire spine. Immunophenotyping and cytogenetic investigations of the girl's cerebrospinal fluid lymphocytosis excluded a late central nervous system relapse of her leukaemia. The diagnosis was acute disseminated encephalomyelitis. With standard immunosuppressive therapy, the girl had early cerebral recovery but a prolonged period of recovery from her myelopathy. Conclusion Acute disseminated encephalomyelitis should be considered in the differential diagnosis of acute encephalomyelopathy after bone marrow transplantation for leukaemia. Demyelinating syndromes such as acute disseminated encephalomyelitis may be late sequelae of bone marrow transplantation. PMID:17411447

    We report a case of acute calculous cholecystitis through scrub typhus. A 69-year-old woman presented with a history of general myalgia, fever, and right abdominal pain. She referred to our hospital for surgical treatment of clinically suspected acute cholecystitis. Physicians concluded the cause of cholecystitis as gall bladder (GB) stone and proper antibiotics treatment of scrub typhus was started later. The patient developed acute respiratory distress syndrome and multi organ failure through scrub typhus. Five days after admission, the patient was treated with proper antibiotics and discharged on the 13th day after starting doxycycline treatment without any sequelae. In areas endemic for tsutsugamushi disease, even though a patient with GB stone presents with symptoms of acute cholecystitis, careful history and physical examination are required to reveal the existence of eschars or skin eruptions.

    Background: Organophosphate (OP) insecticides are widely used in both agricultural and landscape pest control, and the potential for human exposure to these compounds is significant. Objectives: The aims of this study were to investigate the effects of acute poisoning with the OP methamidophos and the effects of antidotal therapy with atropine and pralidoxime on rat thyroid tissue ultrastructure. Methods: In this single-blind, ex vivo study, male Wistar albino rats weighing 220 to 230 g were divided into 4 treatment groups. Group 1 received a median lethal dose of methamidophos (30 mg/kg) via oral gavage. Group 2 received saline via oral gavage and served as the control group for group 1. Group 3 received methamidophos (30 mg/kg) via oral gavage, and after 8 minutes atropine 0.05 mg/kg and pralidoxime chloride (2-FAM) (40 mg/kg) were administered intraperitoneally (IP). Atropine was titrated to reverse signs of cholinergic excess. Group 4 received saline via oral gavage followed by IP injections and served as the control for group 3. Rat thyroid tissues were examined using electron microscopy, and the histologic changes were examined by a histopathologist who was blinded to treatment. All rats were euthanized by intracardiac blood collection. The rats in groups 1 and 2 were euthanized 8 minutes after treatment. The rats in groups 3 and 4 were euthanized 96 hours after treatment. Results: Thirty-four male rats (aged 16 weeks) were included in the study. The rats were grouped accordingly: group 1 (n = 10); group 2 (n = 7); group 3 (n = 10); and group 4 (n = 7). The mean (SD) pseudocholinesterase (FCE) activity was significantly lower in the methamidophos-treated rats (group 1) compared with the corresponding control group (group 2) (32.6 [17.0] vs 579.4 [59.0] U/L, respectively; P < 0.001). PCE activity was significantly higher in rats treated with atropine and 2-PAM (group 3) (392.5 [39.4] U/L; P < 0.001) compared with those not receiving antidotal therapy (group 1

    Neonatal suppurative parotitis is very rare. One review of the English-language literature spanning 35 years found only 32 cases. Most cases are managed conservatively with antibiotic therapy; early antibiotic treatment reduces the need for surgery. The predominant organism is Staphylococcus aureus. We report a new case of neonatal suppurative parotitis in a 3-week-old boy. The patient was diagnosed on the basis of parotid swelling, a purulent exudate from a Stensen duct, and the growth of pathogenic bacteria in culture. He responded well to 9 days of intravenous antibiotic therapy. We also discuss the microbiologic and clinical patterns of this disease.

    Between 1994 and 2006, a total of 280 cases of varying degrees of tetrodotoxin poisoning following ingestion of the toxic eggs of the horseshoe crab, Carcinoscorpius rotundicauda, were admitted to the medical service of Chon Buri Hospital. The severity of the poisoning was classified into four stages based on clinical signs and symptoms of human tetrodotoxication. Of 245 available medical records; 100 were in stage 1, 74 were in stage 2, 3 were in stage 3 and 68 were in stage 4. The frequencies of symptoms and signs included the following : circumoral and lingual numbness (98%), hands and feet numbness (94.7%), weakness (59.6%), dizziness and vertigo (54.3%), nausea and vomiting (52.6%), transient hypertension (39.6%), respiratory paralysis (27.7%), fixed dilated pupils (14.7%), ophthalmoplegia (12.2%), blood pressure lower than 90/60 mmHg (5.7%), and polyuria (0.4%). All patients received symptomatic and supportive treatment. Endotracheal intubation and mechanical ventilation were considered when paralysis was progressing rapidly. The results of treatment are as follows: 239 patients (97.5%) showed complete recovery, 5 patients (2%) died, and 1 patient (0.4%) suffered anoxic brain damage. Horseshoe crab poisoning occurs both sporadically and epidemically in Chon Buri. Seasonal variation in the number of cases of poisoning was observed with a peak from December through March.

  15. Analysis of hydrogen cyanide in air in a case of attempted cyanide poisoning.

    PubMed

    Magnusson, R; Nyholm, S; Åstot, C

    2012-10-10

    A 32-year-old man attempted to poison his ex-girlfriend with hydrogen cyanide by hiding the pesticide Uragan D2 in her car. During the police investigation, chemical analysis of the air inside the car was performed. Hydrogen cyanide was detected through on-site air analysis using a portable Fourier transform infrared (FTIR) spectroscopy gas analyzer and colorimetric gas detection tubes. Furthermore, impinger air-sampling was performed for off-site sample preparation and analysis by gas chromatography-mass spectrometry (GC-MS). All three independent techniques demonstrated the presence of hydrogen cyanide, at concentrations of 14-20 ppm. Owing to the high volatility of hydrogen cyanide, the temperature and the time since exposure have a substantial effect on the likelihood of detecting hydrogen cyanide at a crime scene. The prevailing conditions (closed space, low temperature) must have supported the preservation of HCN in the car thus enabling the identification even though the analysis was performed several days after the hydrogen cyanide source was removed. This paper demonstrates the applicability of combining on-site FTIR measurements and off-site GC-MS analysis of a crime scene in order to ensure fast detection as well as unambiguous identification for forensic purposes of hydrogen cyanide in air.

    2004-03-01

    Cyanide has gained historical notoriety as a poison used with intent to cause fatality. Its occurrence in industry is confined to a small number of uses in a relatively narrow range of industries, including the manufacture of Perspex and nylon and in electroplating. With proper controls in these settings, episodes of poisoning are extremely rare. However, because of the potential for a fatal outcome, procedures for the treatment of acute poisoning are essential. Antidotes include methaemoglobin generators, direct binding agents and sulphur donors, but there is a lack of international consensus about the treatment of choice. This article reviews the mechanisms and treatment of cyanide intoxication and emphasizes the importance of having agreed local procedures for the emergency treatment of poisoning.

    Jejunal pseudo-diverticulosis is a rare acquired herniation of the mucosa and submucosa through weakened areas of the muscularis mucosa of the mesenteric aspect of the bowel. They are asymptomatic in the majority of cases; however, they can present with a wide spectrum of non-specific symptoms such as chronic abdominal discomfort, postprandial flatulence, diarrhoea, malabsorption and steattorhoea. In up to 15% of cases, more serious acute complications may arise such as the development of intestinal obstruction, haemorrhage or as in our case, localized peritonitis secondary to perforation. Perforation carries an overall mortality rate of up to 40% and exploratory laparotomy followed by copious lavage with segmental resection and primary anastomosis remains the mainstay of managing such sequalae of jejunal pseudo-diverticulosis. Our case report highlights the importance of maintaining a high clinical suspicion of a perforated jejunal diverticulum in an elderly patient presenting with an acute abdomen. PMID:27765806

    Two cases of paralytic shellfish poisoning after ingestion of mussels occurred in October 1977 in Nova Scotia. The incidence of this type of poisoning is relatively high among persons living on the coast of the Bay of Fundy and the estuary of the St. Lawrence River. The causative organism, Gonyaulax tamarensis, elaborates an endotoxin, saxitoxin, that blocks neuromuscular transmission in the motor axon and muscle membrane while leaving the end-plate unaffected; it also suppresses conduction in the atrioventricular node and inhibits the respiratory centre. The clinical manifestations are unique and include numbness of the lips, tongue and fingertips within minutes of ingestion of the poisoned shellfish, then numbness of the legs, arms and neck, with general muscular incoordination, and finally respiratory distress and muscular paralysis. Treatment is symptomatic and prevention can only occur by public education. Images FIG. 2 FIG. 3 PMID:570450

  3. Neuroprotective effects of currently used antidotes in tabun-poisoned rats.

    PubMed

    Kassa, Jirí; Krejèová, Gabriela

    2003-06-01

    The neuroprotective effects of antidotes (atropine, pralidoxime/atropine, obidoxime/atropine and HI-6/atropine mixtures) on rats poisoned with tabun at a lethal dose (220 microg/kg intramuscularly; 100% of LD50 value) were studied. The tabun-induced neurotoxicity was monitored using a functional observational battery and an automatic measurement of motor activity. The neurotoxicity of tabun was monitored at 24 hr and 7 days after tabun challenge. The results indicate that atropine alone is not able to protect the rats from the lethal effects of tabun. Three non-treated tabun-poisoned rats and one tabun-poisoned rat treated with atropine alone died within 24 hr. On the other hand, atropine combined with all tested oximes allows all tabun-poisoned rats to survive at least 7 days following tabun challenge. Obidoxime combined with atropine seems to be the most effective antidotal treatment for the elimination of tabun-induced neurotoxicity in the case of lethal poisoning among tested antidotal mixtures. The antidotal mixture consisting of atropine and HI-6 is significantly less effective than the combination of atropine with obidoxime in the elimination of tabun-induced neurotoxicity in rats at 24 hr following tabun challenge. Pralidoxime in combination with atropine appears to be practically ineffective to decrease tabun-induced neurotoxicity at 24 hours as well as 7 days following tabun poisoning. Due to its neuroprotective effects, obidoxime seems to be the most effective and most suitable oxime for the antidotal treatment of acute tabun exposure among currently used oximes. Thus, the replacement of obidoxime by a more effective acetylcholinesterase reactivator for soman poisoning, the oxime HI-6, can to a small extent diminish the neuroprotective efficacy of antidotal treatment in the case of acute tabun poisonings.

    Renal enlargement at time of diagnosis of acute leukemia is very unusual. We here in report 2 pediatric cases of acute leukemia who had their renal affection as the first presenting symptom with no evidences of blast cells in blood smear and none of classical presentation of acute leukemia. The first case is a 4-year-old girl who presented with pallor and abdominal enlargement. Magnetic resonance imaging showed bilateral symmetrical homogenous enlarged kidneys suggestive of infiltration. Complete blood picture (CBC) revealed white blood count 11 × 10⁹/L, hemoglobin 8.7 g/dL and platelet count 197 × 10⁹/L. Bone marrow aspiration was performed, and diagnosed precursor B-cell ALL was made. The child had an excellent response to modified CCG 1991 standard risk protocol of chemotherapy with sustained remission, but unfortunately relapsed 11 month after the end of therapy. The second child was 13-month old, presented with pallor, vomiting, abdominal enlargement, and oliguria 2 days before admission. Initial CBC showed bicytopenia, elevated blood urea, creatinine, and serum uric acid, while abdominal ultrasonography revealed bilateral renal enlargement. Bone marrow examination was done and showed 92% blast of biphenotypic nature. So, biphynotypic leukemia with bilateral renal enlargement and acute renal failure was subsequently diagnosed. The patients admitted to ICU and received supportive care and prednisolone. Renal function normalized and chemotherapy was started. The child achieved complete remission with marked reduction of kidney size but, unfortunately she died from sepsis in consolidation phase of therapy. This case demonstrates an unusual early renal enlargement in childhood acute leukemia. Renal involvement of acute leukemia should be considered in child presenting with unexplained bilateral renal enlargement with or without renal function abnormalities and bone marrow examination should be included in the workup.

    Low volatile organophosphorous nerve agents such as VX, will most likely enter the body via the skin. The pharmacokinetics of drugs such as oximes, atropine and diazepam, are not aligned with the variable and persistent toxicokinetics of the agent. Repeated administration of these drugs showed to improve treatment efficacy compared to a single injection treatment. Because of the effectiveness of continuous treatment, it was investigated to what extent a subchronic pretreatment with carbamate (pyridostigmine or physostigmine combined with either procyclidine or scopolamine) would protect against percutaneous VX exposure. Inclusion of scopolamine in the pretreatment prevented seizures in all animals, but none of the pretreatments affected survival time or the onset time of cholinergic signs. These results indicate that percutaneous poisoning with VX requires additional conventional treatment in addition to the current pretreatment regimen. Decontamination of VX-exposed skin is one of the most important countermeasures to mitigate the effects of the exposure. To evaluate the window of opportunity for decontamination, the fielded skin decontaminant Reactive Skin Decontaminant Lotion (RSDL) was tested at different times in hairless guinea pigs percutaneously challenged with 4× LD50 VX in IPA. The results showed that RSDL decontamination at 15 min after exposure could not prevent progressive blood cholinesterase inhibition and therefore would still require additional treatment. A similar decontamination regimen with RSDL at 90 min showed that it still might effectively increase the time window of opportunity for treatment. In conclusion, the delay in absorption presents a window of opportunity for decontamination and treatment. The continuous release of VX from the skin presents a significant challenge for efficacious therapy, which should ideally consist of thorough decontamination and continuous treatment.

    Despite the present-day extensive application of aripiprazole, there are many cases of its overdose and of poisoning with this compound. The objective of the present study was to detect and quantify aripiprazole in the internal organs and biological fluids of the laboratory animals in case of acute intoxication. The experiments were carried out on white mice of both sexes weighing 20.5 and 25.7 g. Aripiprazole was isolated from the liver, kidneys, brain, and heart as described by A.A. Vasil'eva and from the plasma and urine by the newly developed original methods. Aripiprazole was identified and quantitatively determined in the extracts from the aforementioned organs and tissues with the use of HPLC. The data obtained on the completeness of extraction from the liver, kidneys , and brain of the laboratory animals indicate that aripiprazole accumulated in the highest concentrations in the brain and kidneys within 24 hours after acute poisoning. Ist content was significantly lower in the liver while no traces of aripiprazole were found in the heart of the mice. The methods for aripiprazole isolation from the urine and blood plasma are described. The maximum amounts of aripiprazole were detected in blood plasma within 24 hours after acute intoxication. It is concluded that the proposed methods for aripiprazole isolation from the biological fluids (blood plasma and urine) can be included in the scheme of the chemical toxicological analysis of this compound.

    Obesity represents a global hazard that predisposes to many serious health problems. Various solutions have been proposed to overcome obesity ranging from dietary balance to bariatric surgery. Intragastric balloons are a widely used measure to decrease weight, although they are advocated as safe devices, some major complications have been reported. We report a case of acute pancreatitis after insertion of a gastric balloon for weight reduction. Abdominal pain associated with nausea and vomiting maybe due to acute pancreatitis caused by compression of the pancreas by the balloon. It is advisable that physicians recognise these complications early to avoid serious and severe end-results.

    Postoperative acute cholecystitis is a rare complication of orthopaedic surgery and is unrelated to the biliary tract. In particular, in the case of immediate postoperative state after surgery such as kyphoplasty at the thoracic vertebra, symptoms related to inflammation mimic those of abdominal origin, so the diagnosis and the treatment of acute cholecystitis can be delayed leading to a fatal outcome. It is important that physicians should be aware of the postoperative patient's condition in order to make an early diagnosis and determine treatment. PMID:23060986

    A case of staphylococcal food poisoning was observed in two individuals of the same family after consumption of primosale, a semiripened sheep cheese produced in Sicily. Staphylococcus aureus isolated from the cheese produced enterotoxin C (SEC) and carried both the enterotoxin C (sec) and the toxic shock syndrome toxin (tsst-1) gene. Following this case, an extensive survey was conducted on 971 food samples (raw milk, cheese, meat, and food preparations). S. aureus was detected in 102 of 971 food samples, from all types of food with the exception of ricotta cheese. The tsst-1 gene was present in 42% of the strains, either alone or in combination with other toxin genes. The enterotoxin C gene was the most represented enterotoxin, but it was only found in dairy products. Six S. aureus isolates carried the sea gene alone, two isolates carried both sea and seb, and one isolate carried both sea and sec. A significant percentage (46%) of all isolates carried a toxin gene, creating significant concern that virulent S. aureus can be transmitted through food in Sicily.

    Attention has been paid to neurobehavioral effects of occupational and environmental exposures to chemicals such as pesticides, heavy metals and organic solvents. The area of research that includes neurobehavioral methods and effects in occupational and environmental health has been called "Occupational and Environmental Neurology and Behavioral Medicine." The methods, by which early changes in neurological, cognitive and behavioral function can be assessed, include neurobehavioral test battery, neurophysiological methods, questionnaires and structured interview, biochemical markers and imaging techniques. The author presents his observations of neurobehavioral and neurophysiological effects in Tokyo subway sarin poisoning cases as well as in pesticide users (tobacco farmers) in Malaysia in relation to Green Tobacco Sickness (GTS). In sarin cases, a variety effects were observed 6-8 months after exposure, suggesting delayed neurological effects. Studies on pesticide users revealed that organophosphorus and dithiocarbamate affected peripheral nerve conduction and postural balance; subjective symptoms related to GTS were also observed, indicating the effects of nicotine absorbed from wet tobacco leaves. In addition, non-neurological effects of pesticides and other chemicals are presented, in relation to genetic polymorphism and oxidative stress.

    We have prospectively studied 158 cases of acute hepatitis delta observed during the last 7 years in a general hospital. Among them 136 were male and 22 female. The mean age was 22.7 years with a range between 16 and 61 years. The epidemiologic factors were drug addiction by parenteral route in 145 cases (92%), sexual transmission in 5 (3%), post transfusional in 2 (1%) and unknown in 6 (4%). With respect to the delta type infection, 105 cases (66%) were coinfections with type B and delta, and 53 patients had a type delta superinfection (34%). The clinical course was a fulminant hepatitis in three cases (two cases of coinfection B and delta an one case of delta superinfection), and an acute benign hepatitis in 155 patients. The follow-up of 118 patients revealed that 96% of coinfections by type B and delta evolved to the chronicity showing findings of active chronic hepatitis or hepatic cirrhosis. It should be noted that in 4 cases of superinfection delta type (11%) the HBsAg was negative after several months of positivity. In these patients the level of transaminases normalized and the hepatic histology evidenced alterations of chronic active hepatitis (2 cases) and hepatic cirrhosis (2 cases) without identification of tissular delta antigen.

    The increasing availability of e-cigarettes is a potential toxicological concern. E-cigarettes appeared on the Polish market in 2006, and since 2009 they have been widely available with a new source of nicotine, the so-called e-liquid. In this paper two cases of suicidal oral and intravenous poisonings with the e-liquid are described. The clinical courses of these poisonings are presented. Nicotine and cotinine concentrations in the patient's blood were determined using high performance liquid chromatography with diode array detection. In the course of intoxication patient No. 1, classic symptoms of acute nicotine poisoning without convulsions were observed. Nicotine and cotinine concentrations measured in serum were 0.096 and 4.4mg/L, respectively. The case of patient No. 2, admission with no typical symptoms of nicotine poisoning was identified, except unconsciousness and slow respiration. Nicotine and cotinine concentrations in the serum at the time of No. 2 admissions were determined to be 0.8 and 1.3mg/L, respectively. With the increasing number of e-liquid poisonings cases, it should be aware that these products can be a readily available source of poison.

    Background In 2010, Médecins Sans Frontières (MSF) investigated reports of high mortality in young children in Zamfara State, Nigeria, leading to confirmation of villages with widespread acute severe lead poisoning. In a retrospective analysis, we aimed to determine venous blood lead level (VBLL) thresholds and risk factors for encephalopathy using MSF programmatic data from the first year of the outbreak response. Methods and Findings We included children aged ≤5 years with VBLL ≥45 µg/dL before any chelation and recorded neurological status. Odds ratios (OR) for neurological features were estimated; the final model was adjusted for age and baseline VBLL, using random effects for village of residence. 972 children met inclusion criteria: 885 (91%) had no neurological features; 34 (4%) had severe features; 47 (5%) had reported recent seizures; and six (1%) had other neurological abnormalities. The geometric mean VBLLs for all groups with neurological features were >100 µg/dL vs 65.9 µg/dL for those without neurological features. The adjusted OR for neurological features increased with increasing VBLL: from 2.75, 95%CI 1.27–5.98 (80–99.9 µg/dL) to 22.95, 95%CI 10.54–49.96 (≥120 µg/dL). Neurological features were associated with younger age (OR 4.77 [95% CI 2.50–9.11] for 1–<2 years and 2.69 [95%CI 1.15–6.26] for 2–<3 years, both vs 3–5 years). Severe neurological features were seen at VBLL <105 µg/dL only in those with malaria. Interpretation Increasing VBLL (from ≥80 µg/dL) and age 1–<3 years were strongly associated with neurological features; in those tested for malaria, a positive test was also strongly associated. These factors will help clinicians managing children with lead poisoning in prioritising therapy and developing chelation protocols. PMID:24740291

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

    Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease that is characterized by its chronic course and the involvement of many organs and systems. The most common abnormality in the respiratory system of SLE patients is lupus pleuritis. Less common is parenchymal involvement, which may present as acute lupus pneumonitis (ALP) or chronic interstitial lung disease. Other possible pulmonary manifestations of SLE include pulmonary embolism, diffuse alveolar haemorrhage, acute reversible hypoxaemia, and shrinking lung syndrome. We present the case report of a young woman with previously diagnosed membranous glomerulonephritis with nephrotic syndrome and antiphospholipid syndrome, who was admitted with marked of shortness of breath. The diagnostic process, including imaging studies and laboratory tests, enabled us to confirm a diagnosis of ALP. After initiation of treatment with high doses of methyloprednisolone, nearly complete remission of pulmonary changes was observed. We also perform a literature review regarding acute lupus pneumonitis.

    Organophosphate poisoning is associated with a high mortality rate due to respiratory failure, dysrhythmias, and multi-organ failure. We report two cases of survival after "in-the field" antidote treatment of very severe organophosphate poisonings. Two patients orally ingested large amounts of the organophosphorous agent oxydemeton-methyl in suicide attempts, resulting in the hypercholinergic syndrome in both. Resuscitation included early administration of antidote by emergency medical personnel as well as high-dose atropine. Plasma levels of pseudo cholinesterase were initially very low in both patients. Long-term mechanical ventilation was necessary, and both patients developed aspiration pneumonia. At discharge, no major neurological deficits were present. Prompt antidote treatment and aggressive supportive emergency and intensive care unit therapy contribute to improved survival after acute organophosphate poisoning. We believe that in cases of mass poisonings--for example, terrorist activity--therapy must be available on the scene as soon as possible. This also may require decentralized antidote storage.

    The study represents an attempt at employing segmental hair analysis in complex poisonings with xenobiotic mixtures of heroine - cocaine - amphetamines in the context of the cause of death as a consequence of complex interaction mechanisms which occurred prior to death. Two cases of complex poisonings: heroine - cocaine and heroine - cocaine - amphetamines were analyzed and documented with macro- and microscopic examinations and complex toxicological examinations, including the analysis of classic biological material, i.e. samples of selective blood, and alternative material, i.e. hair samples. Determinations of opioids, cocaine and its metabolite and amphetamines in the hair biological matrix were performed using high performance liquid chromatography--atmospheric pressure chemical ionization--tandem mass spectrometry (HPLC-APCI-MS-MS). Segmental hair analysis of the investigated cases indicated a prolonged intake of similar psychoactive substances and a developed adaptation of the addicted to interaction mechanisms, which, however, led gradually to multiorgan anatomopathological changes, and in consequence to death.

    Hepatic retransplant constitutes 10-20% of all orthotopic hepatic transplants. The piggy-back technique was used in hepatectomy with conservation of the retrohepatic vena cava. A side-to-side cavo-cavostomy technique is described in the case of hepatic congestion or acute Budd Chiari syndrome post-transplant. This is an extremely serious condition and can result in death. We present the first case of hepatic retransplant performed in Hospital Hermanos Ameijeiras in a patient who received who received his first transplant due to non-resectable hepatocarcinoma and who required retransplant due to acute rejection and graft dysfunction. During retransplant, the Belghiti side-to-side anastomosis technique was used to resolve the acute Budd Chiari syndrome that presented itself. Post-surgical evolution at 18 months was satisfactory without evidence of complications of the graft. Acute Budd Chiari syndrome post-transplant can satisfactorily be resolved with the Belghiti technique, although it is preferable to take prophylactic measures to avoid it.

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

    Staphylococcal enterotoxins (SEs) are important causative agents in gastroenteritidis and food poisoning cases. They are serologically grouped into five major classical types, i.e., SEA, SEB, SEC, SED, and SEE. In addition, new SEs, such as SEG through SEM, have recently been identified and characterized. In an attempt to survey the distribution of classical and new SEs in organisms responsible for staphylococcal infections in Taiwan, we developed PCR primers for the genes that define the SEK, SEL, and SEM types. Bacterial strains other than sek, sel, and sem Staphylococcus aureus, including strains of other Staphylococcus species, did not generate any false-positive results when examined with these primers. The expression potential for the sek, sel, and sem types were also determined by reverse transcription-PCR. Together with the PCR primers specific for the classical SEs and other new SEs, including SEG, SEH, SEI, and SEJ, we surveyed the SE genes in S. aureus strains isolated from food poisoning cases. For 147 S. aureus isolates originating from food poisoning cases, 109 (74.1%) were positive for one or more SE genes. Of them, the major classical enterotoxin type was sea (28.6%), followed by seb (20.4%), sec (8.2%), and sed (2.0%). For the new SE types, sei (30.6%) was detected the most often, followed by sek (18.4%), sem (12.9%), and sel (8.2%). Also, 64 (43.5%) of the total bacterial strains had more than one enterotoxin gene.

    In 1955, a benzene mass-poisoning was detected in a shoe factory in Finland. One hundred and forty-seven persons were heavily exposed, and more than 100 had abnormal blood counts. One died and 10 required hospital treatment. This paper deals with a re-examination of the involved workers nine years later. One hundred and twenty-five persons attended for re-examination. Eight had died, two refused, and 11 could not be located. The possibility of death due to benzene poisoning having occurred among these persons was ruled out by checking the national death register. Each of the subjects underwent a haematological examination which included the haemoglobin value and the erythrocyte, reticulocyte, leucocyte, and thrombocyte counts. A differential count of the leucocytes was also made. A randomly chosen group of 86 persons served as a control group. The thrombocytes of the whole patient group and the erythrocytes of the men were significantly lower than those of the controls, whereas the leucocytes of the whole group and the erythrocytes of the women failed to show any statistical difference. In a multiple discriminant function analysis, considering all three counts at the same time, only the men differed slightly from the controls at the re-examination. The analysis also showed that the prognosis of the severe cases did not differ from that of the mild ones, provided the acute stage had been passed. Some illustrative case reports are added. One patient developed leukaemia after a latency of seven years, whereas most of the others—chosen because of grave symptoms in the initial stage—have recovered. The results are discussed from the point of view of prognosis. PMID:5946130

    Background: Higher temperatures have been associated with higher salmonellosis notifications worldwide. Aims: The objective of this paper is to assess the seasonal pattern of Salmonella cases among humans. Material and Methods: The relationship between ambient maximum temperature and reports of confirmed cases of Salmonella in the Republic of Macedonia and Skopje during the summer months (i.e. June, July, August and September) beginning in 1998 through 2008 was investigated. The monthly number of reported Salmonella cases and ambient maximum temperatures for Skopje were related to the national number of cases and temperatures recorded during the same timeframe using regression statistical analyses. The Poisson regression model was adapted for the analysis of the data. Results: While a decreasing tendency was registered at the national level, the analysis for Skopje showed an increasing tendency for registration of new salmonella cases. Reported incidents of salmonellosis, were positively associated (P<0.05) with temperature during the summer months. By increasing of the maximum monthly mean temperature of 1° C in Skopje, the salmonellosis incidence increased by 5.2% per month. Conclusions: The incidence of Salmonella cases in the Macedonian population varies seasonally: the highest values of the Seasonal Index for Salmonella cases were registered in the summer months, i.e. June, July, August and September.

    Acute hemorrhagic leukoencephalitis (AHLE) is a rare demyelinating disease characterized by an acute rapidly progressive fulminant inflammation of the white matter. In this case report, we introduce a case of AHLE in children with an interesting and lengthy process and successful treatment. A previously healthy 13-year-old girl was admitted to the hospital because of fever and loss of consciousness. After 4 days, she was referred to our pediatric intensive care unit in Mashhad, Iran. On admission, she had right-sided parotiditis. With a diagnosis of AHLE, our patient was treated with methylprednisolone, intravenous immunoglobulin, acyclovir, and plasmapheresis. AHLE is a rare and severe demyelinating disease, the mortality and morbidity of which can be decreased by early detection and treatment with steroid therapy, intravenous immunoglobulin, acyclovir, and plasmapheresis.

Aluminum phosphide poisoning causes metabolic acidosis, arrhythmia, acute respiratory distress syndrome and shock, and there is no specific antidote. A 17-year-old male patient was referred to our hospital because of aluminum phosphide poisoning with 1500 mg of aluminum phosphide tablets. The patient’s consciousness was clear but he was somnolent. Vital parameters were as follows: blood pressure: 85/56 mmHg, pulse: 88 beats/min, SpO2: 94%, temperature: 36.4°C. Because of hypotension, noradrenaline and dopamine infusions were started. The patient was intubated because of respiratory distress and loss of consciousness. Severe metabolic acidosis was determined in the arterial blood gas, and metabolic acidosis was corrected by sodium bicarbonate treatment. In addition to supportive therapy of the poisoning, haemodialysis was performed. Cardiac arrest occurred during follow-ups in the intensive care unit, and sinus rhythm was achieved after 10 min of cardiopulmonary resuscitation. The patient was discharged after three sessions of haemodialysis on the ninth day. As a result, haemodialysis contributed to symptomatic treatment of aluminum phosphide poisoning in this case report.

The patient was discharged after three sessions of haemodialysis on the ninth day. As a result, haemodialysis contributed to symptomatic treatment of aluminum phosphide poisoning in this case report.

  13. Amitraz: a mimicker of organophosphate poisoning.

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

    The ability of the newly developed bispyridinium compound K203 and its fluorinated analogue KR-22836 to reduce tabun-induced acute neurotoxic signs and symptoms was compared with the currently available reactivator of acetylcholinesterase-obidoxime. Tabun-induced neurotoxicity and the neuroprotective effects of all tested oximes in combination with atropine in rats poisoned with tabun at a sublethal dose (200 μg/kg intramuscularly (i.m.); 80% of LD(50) value) were monitored by a functional observational battery at 24 hr after tabun challenge. The results indicate that all tested oximes combined with atropine were able to survive tabun-poisoned rats 24 hr after tabun challenge while one non-treated tabun-poisoned rat died within 24 hr after tabun poisoning. All tested oximes combined with atropine were able to decrease tabun-induced neurotoxicity in the case of sublethal poisoning but they did not eliminate all tabun-induced acute neurotoxic signs and symptoms. While the ability to reduce tabun-induced acute neurotoxicity of obidoxime and K203 was similar, the neuroprotective efficacy of KR-22836 was slightly higher compared to other tested oximes. Thus, the newly developed fluorinated analogue of K203, called KR-22836, is able to slightly increase the neuroprotective effectiveness of antidotal treatment of acute tabun poisonings compared to K203 and currently available obidoxime.

  15. Propylene Glycol Poisoning From Excess Whiskey Ingestion: A Case of High Osmolal Gap Metabolic Acidosis.

    2015-01-01

    In this report, we describe a case of high anion gap metabolic acidosis with a significant osmolal gap attributed to the ingestion of liquor containing propylene glycol. Recently, several reports have characterized severe lactic acidosis occurring in the setting of iatrogenic unintentional overdosing of medications that use propylene glycol as a diluent, including lorazepam and diazepam. To date, no studies have explored potential effects of excess propylene glycol in the setting of alcohol intoxication. Our patient endorsed drinking large volumes of cinnamon flavored whiskey, which was likely Fireball Cinnamon Whisky. To our knowledge, this is the first case of propylene glycol toxicity from an intentional ingestion of liquor containing propylene glycol.

    F10 is an oligonucleotide based on the thymidylate synthase (TS) inhibitory 5-fluorouracil (5-FU) metabolite, 5-fluoro-2'-deoxyuridine-5'-O-monophosphate. We sought to determine the activity of F10 against preclinical models of acute lymphoblastic leukemia (ALL). F10 treatment resulted in robust induction of apoptosis that could not be equaled by 100 fold more 5-FU. F10 was more potent than Ara-C and doxorubicin against a panel of murine and human ALL cells with an average IC50 value of 1.48 nM (range 0.07 to 5.4 nM). F10 was more than 1000 times more potent than 5-FU. In vivo, F10 treatment significantly increased survival in 2 separate syngeneic ALL mouse models and 3 separate xenograft models. F10 also protected mice from leukemia-induced weight loss. In ALL cells made resistant to Ara-C, F10 remained highly active in vitro and in vivo. Using labeled F10, uptake by the ALL cell lines DG75 and SUP-B15 was rapid and profoundly temperature-dependent. Both cell lines demonstrated increased uptake compared to normal murine lineage- depleted marrow cells. Consistent with this decreased uptake, F10 treatment did not alter the ability of human hematopoietic stem cells to engraft in immunodeficient mice.

    Sorafenib is a multikinase inhibitor that is used for the treatment of metastatic renal-cell carcinoma. We report the case of a patient with painless acute pancreatitis associated with sorafenib treatment. The patient was a 71-year-old man who had undergone surgery for left renal carcinoma and tumor thrombus in the inferior vena cava and right atrium (IVC-RA). After a follow-up period of 3 years, he developed right adrenal metastasis and received interferon (IFN)-alpha treatment. One year later, progression of the adrenal metastasis was observed, and he was admitted to a hospital for treatment with sorafenib, which was administered at a dose of 800 mg/day. Two weeks later, he developed painless acute pancreatitis associated with sorafenib treatment. Thereafter, sorafenib treatment was discontinued, and he was treated with conservative therapy. Three weeks later, he was discharged. Even though painless acute pancreatitis associated with sorafenib treatment is rare, the possible development of painless acute pancreatitis in patients undergoing sorafenib treatment must be kept in mind.

    Two small boys were admitted to the Lions Gate Hospital in coma and acute respiratory distress. They improved and the first boy was sent home; after two nights he was back in hospital in a worsened state. Poisoning with organic phosphate was suspected, and after investigation some flannelette sheets were taken from his home for testing. They proved to have been contaminated with parathion (“nerve gas”) in the hold of a ship sailing from Antwerp to Vancouver; the parathion had been offloaded in California. The remainder of the sheets were traced. The symptomatology and treatment of organic phosphate ester poisoning and the chemical testing of parathion are discussed. PMID:14272498

  2. Sodium fluoroacetate poisoning.

    2006-01-01

    liberated from fluoroacetate, citrate and fluorocitrate are calcium chelators and there are both animal and clinical data to support hypocalcaemia as a mechanism of fluoroacetate toxicity. However, the available evidence suggests the fluoride component does not contribute. Acute poisoning with sodium fluoroacetate is uncommon. Ingestion is the major route by which poisoning occurs. Nausea, vomiting and abdominal pain are common within 1 hour of ingestion. Sweating, apprehension, confusion and agitation follow. Both supraventricular and ventricular arrhythmias have been reported and nonspecific ST- and T-wave changes are common, the QTc may be prolonged and hypotension may develop. Seizures are the main neurological feature. Coma may persist for several days. Although several possible antidotes have been investigated, they are of unproven value in humans. The immediate, and probably only, management of fluoroacetate poisoning is therefore supportive, including the correction of hypocalcaemia.

  3. A drug from poison: how the therapeutic effect of arsenic trioxide on acute promyelocytic leukemia was discovered.

    2013-06-01

    It is surprising that, while arsenic trioxide (ATO) is now considered as "the single most active agent in patients with acute promyelocytic leukemia (APL)", the most important discoverer remains obscure and his original papers have not been cited by a single English paper. The discovery was made during the Cultural Revolution when most Chinese scientists and doctors struggled to survive. Beginning with recipes from a countryside practitioner that were vague in applicable diseases, Zhang TingDong and colleagues proposed in the 1970s that a single chemical in the recipe is most effective and that its target is APL. More than 20 years of work by Zhang and colleagues eliminated the confusions about whether and how ATO can be used effectively. Other researchers, first in China and then in the West, followed his lead. Retrospective analysis of data from his own group proved that APL was indeed the most sensitive target. Removal of a trace amount of mercury chloride from the recipe by another group in his hospital proved that only ATO was required. Publication of Western replication in 1998 made the therapy widely accepted, though neither Western, nor Chinese authors of English papers on ATO cited Zhang's papers in the 1970s. This article focuses on the early papers of Zhang, but also suggests it worth further work to validate Chinese reports of ATO treatment of other cancers, and infers that some findings published in Chinese journals are of considerable value to patients and that doctors from other countries can benefit from the clinical experience of Chinese doctors with the largest population of patients.

    The purpose of this investigation was to determine the cause of death of a 13-year-old girl, where none was immediately evident. Our analysis showed it to be a very unusual case of a drug-facilitated sexual assault (DFSA), which led to the tragic death of the young rape victim and then to the suicide of the rapist. The incapacitating agent used was chloroform. The post-mortem analysis revealed a blood concentration of 833.9 mg/l for the girl, whereas the quantitation of chloroform in various fluids and viscera of the rapist proved that he had recently been handling the solvent (with concentrations in fat tissues 20 times higher than in his blood). This case draws attention to the need for broad searches for volatile substances in such investigations.

  6. Acute pancreatitis with saw palmetto use: a case report

    PubMed Central

    2011-01-01

    Introduction Saw palmetto is a phytotherapeutic agent commercially marketed for the treatment of benign prostatic hyperplasia. Evidence suggests that saw palmetto is a safe product, and mild gastrointestinal adverse effects have been reported with its use. We report a case of acute pancreatitis, possibly secondary to the use of saw palmetto. Case presentation A 61-year-old Caucasian man with a history of benign prostatic hyperplasia and gastroesophageal reflux disease developed epigastric pain associated with nausea 36 hours prior to presentation. He denied drinking alcohol prior to the development of his symptoms. His home medications included saw palmetto, lansoprazole and multivitamins. Laboratory results revealed elevated lipase and amylase levels. An abdominal ultrasound demonstrated a nondilated common bile duct, without choledocholithiasis. Computed tomography of his abdomen showed the pancreatic tail with peripancreatic inflammatory changes, consistent with acute pancreatitis. Our patient's condition improved with intravenous fluids and pain management. On the fourth day of hospitalization his pancreatic enzymes were within normal limits: he was discharged home and advised to avoid taking saw palmetto. Conclusion It is our opinion that a relationship between saw palmetto and the onset of acute pancreatitis is plausible, and prescribers and users of saw palmetto should be alert to the possibility of such adverse reactions.

    It takes about 2 weeks for the onset of antidepressant action of drugs while electroconvulsive therapy though faster, is a cumbersome procedure requiring an anaesthetist and at least a minor operation theatre. Recent studies have shown that Ketamine, when given to severely depressed patients in the dose of 0.5 mg/kg as a slow intravenous infusion over 40 minutes, brought about acute relief from depression and amelioration of suicidal risk within a few hours. The improvement, however, was transient and lasted for up to a week but could be sustained by further weekly or biweekly injections. As the dose of ketamine administered was found to be safe, it was now tried in the intramuscular route in two severely depressed patients with similar rapid improvement. The cases are reported here which pave way for an easier mode of treating acute depression. PMID:23825857

    Acute erythroleukemia (AEL) is a rare form of acute myeloid leukemia (AML) often associated with a poor prognosis. It is more frequent in elderly patients, limiting the use aggressive therapies. Azacitidine is a hypomethylating agent with recognized efficacy in high risk myelodysplasia and AML in the elderly. Here we report 5 cases of AEL treated with Azacitidine. The cohort included 4 men and 1 woman, median age 70. One patient had been refractory to intensive chemotherapy, the others received Azacitidine as first line. Treatment was well tolerated. Four patients achieved transfusion independence. Two patients achieved complete remission and 1 achieved partial remission. After a median follow up time of 20 months, the median survival of the cohort was 20 months. Three patients died of disease progression. These results confirm the therapeutic value of Azacitidine in AEL. PMID:24371777

    Primary hyperparathyroidism (PHPT) is a disorder of calcium homeostasis. We report the case of a 17-year-old adolescent male, who presented with an acute psychosis coinciding with severe hypercalcemia and markedly elevated intact parathyroid hormone (iPTH) level and low vitamin D level. A Sestamibi scan showed a positive signal inferior to the left lobe of the thyroid gland. He had only a partial response to the initial medical and psychiatric management. The enlarged parathyroid gland was resected surgically and postoperatively serum calcium and iPTH levels normalized. The histopathology was compatible with a benign adenoma. Patient's acute psychotic symptoms resolved gradually after surgery; however he remained under psychiatric care for the behavioral issues for about 6 months after surgery. While psychosis is a rare clinical manifestation of hypercalcemia secondary to PHPT in pediatric population, it should be considered as a clinical clue in an otherwise asymptomatic pediatric patient.

    Acyclovir has been a frequently used antiviral agent in the clinical treatment of leukemia, acute encephalitis, malignant tumor and herpes simplex. The adverse effects of this drug have been widely described in clinical practice. In the present study, a case of a 35-year-old female patient diagnosed with herpes simplex, who developed acute renal injury following treatment with valacyclovir hydrochloride, is described. Kidney biopsy, light microscopy and laboratory examination were performed, and all findings revealed the signs of evident vacuolar degeneration of capillary endothelial and renal tubular epithelial cells, erythrocyte aggregation in partial renal tubule and microvilli exfoliation from epithelial cells. Renal interstitial edema was clearly identified. The clinical evidence observed from this female patient indicated that renal functions should be closely monitored during valacyclovir hydrochloride administration. A variety of effective measures, such as hydration, alkalizing urine, promoting the discharge of medication and the use of antagonists are recommended following the administration of antiviral agents.

    Since 2008, the Institut Catala de la Salut (ICS) introduced the nurses management plan for acute pathology, in primary care centres. In the implementation of this system of organization, the ICS introduced various diseases protocols with performance algorithms. To raise awareness of the the practice of acute pathology, we present a clinical case. An urgent consultation of a 30 year-old male, with fever, sore throat and cough, which was managed and resolved by a nurse. The aim of this new management plan is that nursing is the first health professional to take care of patient coming to primary care centre without a scheduled visit, to avoid saturating the general clinic or hospital emergencies. This new organisational system involves an increase in the responsibilities of nursing in the diagnosis and treatment of patients.

    In past year drug abuse becomes more and more general in Hungary. In addition to consume traditional drugs, other substances are used frequently too. One of them is the Datura stramonium, which contains alkaloids (mostly atropine), and can result in hallucinations. Therefore Datura stramonium is seemingly becoming popular as a hallucinogenic drug. The consumption of any part of the plant causes atropine intoxication, thus anticholinergic delirium. Differential diagnosis of Datura intoxication can be difficult in the everyday medical practise. In our paper the symptomatology, diagnosis, differential diagnosis, and therapy of Datura intoxication are discussed and we report one of our cases.

    Paraphenylene diamine (PPD) hair dye poisoning is a common health problem in the Middle East and Indian subcontinent. It is the most common cause of suicide intent especially among females. We hereby present a 27-year-old female who presented with a clinical feature of PPD poisoning due to a suicidal attempt, and she died soon after arrival. She had survived a previous suicide attempt with PPD 4 years before. This time she also intentionally tried to kill her four children using PPD. One child died, one recovered after dialysis for acute kidney injury and the other two survived without any further intervention. This case illustrates that PPD poisoning may be used in filicide and suicide intent and that all patients who committed suicide should be reviewed and assessed by clinical psychiatrist.

    Benzalkonium chloride is commonly found in household products. This retrospective study examined 245 cases of feline exposure to benzalkonium chloride-containing products reported to the Veterinary Poisons Information Service (VPIS). A single route of exposure was reported in 188 cats (ingestion 126, skin 58, buccal 4); 57 cats had multiple routes. The common products involved were household antibacterial cleaners (43.6 per cent), household disinfectants (22.3 per cent) and patio cleaners (17.5 per cent). The most common signs were hypersalivation/drooling (53.9 per cent), tongue ulceration (40.4 per cent), hyperthermia (40.4 per cent) and oral ulceration (22.9 per cent). The mean time recorded for onset of the first clinical sign was 6.4 hours (range five minutes to 48 hours, median 4.5 hours, n=60), however, the VPIS was not contacted until 14.0 ± 13.2 hours after exposure (n=120). This figure also reflects the time of presentation. The most common treatments given were antibiotics (82.0 per cent), fluids (50.2 per cent), analgesia (45.3 per cent), gastroprotectants (31.0 per cent), dermal decontamination (24.1 per cent) and steroids (22.7 per cent). 13 cats (5.3 per cent) received syringe or nasogastric feeding. Of 245 cats, 12 (4.9 per cent) remained asymptomatic, 230 (93.9 per cent) recovered and three died (1.2 per cent). The time to recovery ranged from 1 to 360 hours (n=67) with a mean of 100.4 ± 82.0 hours (4.2 ± 3.4 days, median 72 hours).
